1 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3 * sort.c (quicksort): Added condition to protect the algorithm
4 from crashing the interpreter if the less predicate is buggy.
6 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
8 * fports.c (fport_write): fix line-buffering mode again.
9 (scm_open_file): recognise 'l' for line-buffering.
10 (scm_setvbuf): recognise _IOLBF for line-buffering.
12 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
14 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
17 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
20 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
22 * fports.c (fport_write): use memcpy instead of strncpy, in case
23 the data contains NUL.
25 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
27 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
29 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
30 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
31 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
32 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
33 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
34 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
35 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
36 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
37 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
38 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
39 scm_sym_ as prefix for symbols.
41 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
43 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
44 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
45 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
46 scm_sym_atcall_cc): Made global.
48 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
50 * eval.c (scm_sym_args): Made global.
52 * objects.c (scm_set_object_procedure_x): Disallow setting of
53 procedures for pure generic functions.
55 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
57 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
58 Scheme name from lseek to seek, but lseek was added recently so
59 it shouldn't be a big problem.
60 * ports.c, gdbint.c, ioext.c: changed callers.
62 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
64 * fports.c (fport_input_waiting): if select is used, return 1
65 instead of whatever FD_ISSET expands to. maybe it will be useful
66 to interpret the value from the input_waiting ptob procedure as a
67 lower bound on the number of bytes available.
69 * Mikael asked for a few names to be changed...
71 * ports.c (scm_make_port_type): take the write procedure as the
72 second argument instead of the flush procedure.
73 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
74 fflush -> flush, read_flush -> end_input, fclose -> close,
75 fill_buffer -> fill_input, ftruncate -> truncate,
76 input_waiting_p -> input_waiting.
78 * ports.c (end_input_void_port): was read_flush_void_port.
79 (scm_set_port_end_input): was scm_set_port_flush_input.
80 (scm_set_port_flush): was scm_set_port_write.
81 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
82 (scm_end_input): was scm_read_flush.
83 (scm_fill_input): was scm_fill_buffer.
84 (scm_flush): was scm_fflush.
85 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
86 (fport_end_input): was local_read_flush.
87 (fport_flush): was local_fflush.
88 (fport_close): was local_fclose.
89 (fport_truncate): was local_ftruncate.
90 (fport_seek): was local_seek.
91 (fport_free): was local_free.
92 (fport_fill_input): was fport_fill_buffer.
93 * strports.c (st_end_input): was st_read_flush.
94 (st_truncate): was st_ftruncate.
95 * vports.c: (sf_flush): was sfflush.
96 (sf_close): was sfclose.
97 (sf_fill_input): was sf_fill_buffer.
99 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
102 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
104 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
105 forms now contain the expressions to be dispatched upon instead of
106 depending on a surrounding lambda or let; Generic function
107 dispatch has been optimized; `apply' on a generic function now
108 works a little bit strangely. It uses a trick so that the type
109 dispatch code in SCM_CEVAL can be reused.
111 * objects.h, objects.c (scm_apply_generic_env): Added (used by
113 (scm_operator_p): Added.
114 (scm_sym_atdispatch): Added.
115 (scm_set_object_procedure_x): Modified to handle the new style
117 (scm_object_procedures): New debugging procedure.
119 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
121 * eval.c, eval.h (scm_sym_args): Added.
123 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
125 * feature.c, feature.h (scm_c_run_hook): Added.
127 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
128 cdrxnoap and loopnoap instead of begin and loop.
130 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
132 * ports.c (scm_putc, scm_puts),
133 * unif.c (scm_uniform_array_write): use scm_lfwrite.
134 * ports.c (scm_putc): change type of first argument from int to char.
136 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
138 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
139 SCM_IM_HASH_DISPATCH.
141 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
142 (scm_si_redfined, scm_si_hashsets): Moved.
144 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
145 flag which combines type and status info so that the class
146 redefinition protocol has zero cost during normal execution.
148 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
150 * ports.h (scm_ptob_descriptor): include a write procedure again.
151 it's more efficient for unbuffered fports (e.g., sockets.)
153 * ports.c (scm_puts): use ptob->write.
154 * vports.c (scm_make_sfptob): set write proc in ptob.
155 * strports.c (scm_make_stptob): set write proc in ptob.
156 * ports.c (write_void_port): new procedure.
157 * vports.c (sf_write): new procedure.
158 * ports.c (scm_lfwrite): use ptob->write.
159 * strports.c (st_write): new procedure.
160 * fports.c (fport_write): new procedure.
161 (scm_make_fptob): set write in ptob to fport_write.
162 * ports.h: prototype for scm_set_port_write.
163 * ports.c (scm_make_port_type): initialise ptob write procedure.
164 (scm_set_port_write): new proc.
166 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
168 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
169 until we've verified that it is actually a port. (Thanks to
172 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
174 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
175 code, particularly an unnecessary test (len != size, where len ==
176 size). (Was this leftovers from debugging code, or have I missed
179 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
180 size. (Thanks to James Dean Palmer.)
182 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
183 (Thanks to Lorentey Karoly.)
185 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
187 * eval.c (scm_m_expand_body): Use scm_cons_source.
189 * struct.c (scm_print_struct): Use vtable name.
191 * print.c (scm_init_print): Set name of print state type.
193 * stacks.c (scm_init_stacks): Set name of stack type.
195 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
197 * eval.c (SCM_CEVAL): Removed old implementation of internal
200 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
202 * debug.c, debug.h (scm_reverse_lookup): Added.
203 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
204 internal procedure definitions; Don't use scm_i_inner_name.
206 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
209 * eval.h: Added prototypes for multi language support functions.
211 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
212 improper lists in the low-level representation, since that will
213 cause a begin to be prepended at macro expansion.
215 * eval.c (scm_cons_source): Version of cons which copies source
216 properties from an existing cell.
217 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
219 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
220 procedure source before calling scm_unmemocopy instead of faking
223 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
225 Ported `internal defines' fix from SCM. Original ChangeLog entry:
227 1998-07-09 Radey Shouman <radey@colorage.com>
229 * eval.c (ceval_1): Modifications to allow rewriting of interal
230 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
231 body of which it is the CAR is macro expanded by m_expand_body,
232 which rewrites internal DEFINE.
234 (m_expand_body): Added.
236 (m_macroexp1): Added argument to control error checking:
237 m_expand_body may speculatively expand forms in the wrong
238 environments. Made argument number checks conditional on
241 (m_body): Added, error checks bodies and inserts the ISYM tokens.
243 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
246 (m_cond): (m_case): (m_quote): Modified to avoid destructively
247 changing their argument forms. Since m_expand_body
248 speculatively macro expands forms the process must be
251 (m_ident_eqp): Fixed to use proper environment.
253 (renamed_ident): Added DEFER_INTS_EGC.
255 Added prototypes for static functions.
261 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
262 is false, do not produce an error for unbound variables, return a
263 pointer to cell_undef instead.
265 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
269 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
270 destructively changing their argument forms. Since m_expand_body
271 speculatively macro expands forms the process must be reversible.
273 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
274 SCM_IM_LET introduced by named lets.
276 (scm_m_letstar): Use scm_m_body instead of bodycheck.
278 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
279 scm_letrec. scm_letrec1 does not check for a null binding and
280 takes an additional argument to specify the ISYM of the body. Use
281 scm_m_body instead of bodycheck.
283 (scm_m_let): Use scm_m_body instead of bodycheck.
285 (scm_m_expand_body, scm_macroexp): New.
287 (unmemocopy): Account for ISYMs introduced by scm_m_body.
289 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
290 check=1. Throw error for internal defined that have not been
291 rewritten by scm_m_expand_body.
293 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
294 Removed prototype for SCM_APPLY.
296 * tags.h: Added extern declaration of scm_isymnames.
298 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
300 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
302 * lang.c: New file: Beginning of multi-language support.
304 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
306 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
307 (scm_dynamic_wind): Added argument checking for the after guard so
308 that we don't add garbage on the dynwind chain.
309 (scm_swap_bindings): Added.
311 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
312 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
313 (scm_isymnames): New isyms for multi-language support.
315 * eval.c (scm_nil, scm_t): New symbols.
316 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
317 forms for multi-language support.
319 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
321 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
323 Renamed functions in the random function library interface
324 from scm_i_XXX --> scm_c_XXX.
326 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
328 * ports.c (scm_putc): fix line-buffering.
330 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
332 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
333 scm_set_ptob_XXX --> scm_set_port_XXX.
335 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
337 * ports.c, ports.h (scm_make_port_type): New interface for
338 creation of port types (replaces scm_newptob). Just as for the
339 smobs, we need to separate the internal representation of smob
340 types from the interface, so that we easily can add new fields and
341 rearrange things without caring about backward compatibility.
342 This change was forced by the need in GOOPS to create classes
343 representing port types.
344 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
345 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
346 scm_set_ptob_seek, scm_set_ptob_truncate,
347 scm_set_ptob_input_waiting_p): New setters.
348 (scm_newptob): Rewritten to use scm_make_port_type. For backward
350 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
351 (scm_prinport): Removed.
352 (scm_port_print): Added.
353 (scm_print_port_mode): Added.
354 (void_port_ptob, print_void_port, close_void_port, noop0):
355 Removed. Removed #include "genio.h" Added #include "objects.h",
358 * fports.c (prinfport): Moved code from ports.c.
360 (scm_fptob): Removed. Instead use new interface.
361 (scm_make_fptob): Added. (Need to create basic ports in a
362 specific order in ports.c.)
364 * strports.c (scm_stptob, prinstpt, noop0): Removed
365 (scm_make_stptob): Added.
367 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
368 (scm_make_sfport): Added.
370 * filesys.c (scm_dir_print): Don't use the port printing code.
371 Instead provide specific directory printer.
373 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
375 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
378 * smob.c (scm_smob_print): Handle non-existing type name nicely.
379 Removed #include "genio.h"
381 * objects.c (scm_make_port_classes): New function ptr.
383 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
385 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
387 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
388 allow the 1st argument to be a fdes or filename as well as a
389 port (as in the filesys.c version).
391 * filesys.c (scm_truncate_file): removed.
393 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
395 * readline.c, readline.h: Removed.
397 * objects.c, objects.h (scm_port_class): Added.
398 (scm_class_of): Look up port class in scm_port_class.
399 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
400 SCM_INOUT_PCLASS_INDEX): Added.
403 * Makefile.am: Removed genio.c, genio.x.
407 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
409 * init.c: Make sure that scm_post_boot_init_modules is called only
410 once. (Important when using a dumped image.; Thanks to Bernard
413 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
415 * guardians.c (scm_guardian_zombify): Separate scanning for
416 zombies from marking the pairs of the free list.
418 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
419 use the macros. (Thanks to Michael Livshin.)
421 * eval.c (scm_m_lambda): Let bodycheck check the body of the
422 lambda. Let your sins be purified by the blood of the lambda.
423 (Thanks to Eric Hanchrow.)
425 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
426 (Thanks to Valdis Kletnieks.)
428 Fixes for EMX from Mikael Ståldal.
430 * filesys.c: #include <io.h>, if we have it.
431 * scmconfig.h.in: Regenerated.
433 * stime.c (ftime): Delete declaration for this function --- let
434 the system supply it.
436 Cleanups from John Bley.
438 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
440 * gsubr.c: Don't include "gsubr.h" twice.
442 Cleanups for compilation on Irix 6, from David Kaelbling.
444 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
445 regex_t pointer. This is what the callers have, mostly.
446 (scm_regexp_exec): Don't forget to pass the `rx' argument to
447 scm_regexp_error_msg.
449 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
450 int. That way, if we get a warning on this line, it's more likely
451 that we're really missing bits we care about.
453 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
456 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
457 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
458 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
459 cast at all is more appropriate in every case. At the moment, we
460 assume everywhere that SCM is an integral type anyway.
462 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
464 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
465 read_pos after scm_fill_buffer.
467 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
470 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
471 fports.c (fport_fill_buffer): implement the interface change.
473 * ports.c (scm_fill_buffer): interface change: no longer increments
474 read_pos past the character that's returned. it seems clearer to
475 leave it to the caller to decide what to do (thanks Jim).
477 * vports.c (sf_fill_buffer): put the read char into the buffer
478 as well as returning it.
480 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure
483 1999-07-13 Gary Houston <ghouston@easynet.co.uk>
485 * strports.c (scm_strprint_obj): simplify. start with initial
487 (st_seek): don't allow string to be extended if seeking past
488 the end of a read-only port.
490 1999-07-12 Gary Houston <ghouston@easynet.co.uk>
492 * strports.c (st_seek): change the resize checks.
494 * ports.c (scm_ftruncate): throw error if offset works out negative.
496 * strports.c (st_flush): increase string size in blocks of
497 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
498 it's greater and reset read_buf_size.
499 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
500 to be maintained for output ports too (it holds the written
501 part of the string, while write_buf may have unwritten buffer
503 (st_truncate): rewritten.
504 (top of file): added a few notes.
506 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
508 Patch from Greg Badros:
509 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
510 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
511 (function pointer) argument to scm_make_gsubr and scm_make_subr
512 calls. This avoids warnings in C++ programs using guile-snarf.
514 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
516 * strports.c (st_grow_port): set pt->read_pos. set
517 pt->read_buf_size one less than pt->write_buf_size if there's
518 an unwritten char at the end of the string. similarly for
520 (st_resize_port): renamed from st_grow_port.
521 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
522 seek from read_end instead of write_end for SEEK_END.
523 (st_ftruncate): calculate current length using readbuf, not write
525 (scm_strport_to_string): use read_buf_size for length.
526 (stfill_buffer): don't re-initialise the readbuf.
528 1999-07-05 Gary Houston <ghouston@easynet.co.uk>
530 * strports.c (scm_strport_to_string): new procedure.
531 (scm_call_with_output_string, scm_strprint_obj): use
532 scm_strport_to_string.

721 surrounded by parens. It's more readable.
723 * eval.c (scm_map, scm_for_each): Verify that all arguments are
724 proper lists, and of the appropriate lengths.

770 instead of stepping through an array.
771 (scm_gc_sweep): Update offset used to find start of weak vector to
773 (scm_init_storage): Set scm_weak_vectors to EOL.
775 Fix from Ken Raeburn <raeburn@raeburn.org>:
776 * gc.c (already_in_gc): New variable.
777 (scm_igc): Set and clear already_in_gc; abort if it's set at

782 Fix from Gary Houston:
783 * fports.c (local_seek): Signal an error if the seek fails.
784 * ports.c (scm_lseek): Don't check return value of port's seek

797 ChangeLog entries and the patch from two different places...
799 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
801 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
802 it shows up as terrible performance, as we GC constantly.
804 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
805 newline. A bit faster, and definitely hairier.
806 (scm_read_line): Count newlines here instead.
808 * strings.c (scm_take_str): New function.
809 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h

814 * ports.h (SCM_BUFLINE): New flag for ports.
815 * init.c (scm_init_standard_ports): Request line-buffering on
816 the standard output port.

819 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
820 and there's a newline to be written, flush the port.
822 Gary Houston's open-buffer port patches:
824 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
826 * ports.c: (scm_lseek): clear buffers even if just reading current
829 * fports.c (local_fclose): call local_fflush unconditionally.

835 strports.c: take care of rw_active and rw_randow.
836 fports.c: scm_fport_drain_input: removed. do it all in ports.c.
837 strports.c (scm_mkstrport): check that pos is reasonable.
838 ioext.c (scm_ftell, scm_fseek): use lseek.
839 (SCM_CLEAR_BUFFERS): macro deleted.

846 strports.c (st_seek, st_grow_port): new procs.
847 fports.h (scm_port): change size types from int to off_t.
848 ports.c (scm_init_ports): initialise the seek symbols here
849 instead of in ioext.c.
850 strports.c (scm_call_with_output_string): start with an empty
851 string, so seek and ftruncate can be used.
853 gdbint.c: adjust string port usage.
855 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
857 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
858 equivalent to fflush for the read buffer.
859 * ports.c (scm_newptob): set read_flush.
860 ports.c (void_port_ptob): set read_flush.
861 fports.c (local_read_flush): new proc. add to ptob.
862 strport.c (st_read_flush): likewise.
863 vport.c (sf_read_flush): likewise.
864 fports.h (struct scm_fport): remove random member. there's nothing
865 left but fdes. leaving it as a struct to allow for future changes.
866 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
867 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
868 ptob proc if the read buffer is filled.
870 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
872 * ports.h (scm_port): add a rw_random member and replace
873 reading and writing members with rw_active member.
874 SCM_PORT_READ/SCM_PORT_WRITE: new values.
876 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
878 * ports.h (struct scm_port_table): add writing and reading members
879 to replace write_needs_seek: it isn't good enough for non-fports.
880 ports.c, ioext.c, fports.c: corresponding changes.
881 (struct scm_port_table): give it a typedef and rename to scm_port.
882 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
883 corresponding changes.
885 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
887 * ports.c (scm_newptob): bugfix: set seek member.
888 * * (scm_lseek): new procedure, using code from ioext.c:scm_fseek

893 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
894 signals (it was only being done for handlers installed from Scheme).
895 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
896 waiting for input caused an EINTR error from read.
898 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
900 * ports.h (struct scm_port_table): make all the char members
901 unsigned, so they convert to int without becoming negative if large.
903 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
905 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
906 with threads enabled. rename this procedure to
907 fport_wait_for_input and take a port instead of a fdes.
908 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
910 * readline.c (scm_readline): Applied a patch from Greg Harvey to
911 get readline support working again: use fdopen to get FILE objects.
913 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
915 * gc.c (scm_init_storage): install an atexit proc to flush the
917 (cleanup): the new proc. it sets a global variable which can be
918 checked by the ptob flush procs to avoid trying to throw
919 exceptions during exit. not very pleasant but it seems more reliable.
920 * fports.c (local_fflush): check terminating variable and if set
921 don't throw exception.
922 * CHECKME: that the atexit proc is installed if unexec used.
924 * throw.c (scm_handle_by_message): don't flush all ports here.
925 it still causes bus errors.
927 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
930 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
932 * ports.c (scm_char_ready_p): check the port buffer and call the
933 ptob entry if needed.
935 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
936 ptob initialisers. use it in char-ready
938 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
940 * vports.c (sfflush): modified to write a char (since softports
941 currently use shortbuf.)
943 * fports.c (scm_standard_stream_to_port): moved to init.c and
946 * init.c (scm_init_standard_ports): make stdout and stderr
947 unbuffered if connected to a terminal. with stdio they
948 were line-buffered by default.
950 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
953 * ports.h (scm_ptobfuns): change fflush return to void.
954 change flush proc definitions.
956 * strports.c (scm_call_with_output_string): get size from
957 buffer instead of port stream.
958 (st_flush): new proc.
960 * ports.h (struct scm_port_table): added write_end member,
961 as an optimisation. set it where write_buf_size is set.
963 * ports.h (struct scm_port_table): change stream from void *
964 back to SCM. SCM presumably must be large enough to hold a
965 pointer (and probably vice versa but who knows.)
966 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
968 (scm_puts): rewritten
969 * fports.c (local_ffwrite, local_fputs): removed.
970 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)
971 * vports.c (sfputc, sfputs, sfwrite) likewise.

981 * ports.h (scm_ptobfuns): add seek function pointer.
982 * fports.c: set it to local_seek, new procedure.
985 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
986 use ptob for seek. take ptob instead of fport arg.
988 * ports.h (struct scm_port_table): new member write_needs_seek,
989 replaces reading member in fport struct.
991 * vports.c (sfgetc): store the getted char into the buffer.
992 rename to sf_fill_buffer and install it for fill-buffer in ptob.
993 the Scheme interface is still a procedure that gets a char.
994 (scm_make_soft_port): set up the port buffer (shortbuf).
996 * fports.c (local_fgetc, local_fgets): deleted.
997 * strports.c (stgetc): likewise.
998 * ports.c: scm_generic_fgets: likewise.
1000 * ports.h (scm_ptobfuns): add fill_buffer.
1001 * ports.c (scm_newptob): assign it.
1002 * strports.c (scm_mkstrport): set up the buffer.
1003 put just the string into the stream, not cons (pos stream).
1004 (stfill_buffer): new proc.
1006 * ports.h: fport buffer moved into port table: to be
1007 used for all port types.
1009 1998-12-20 Gary Houston <ghouston@easynet.co.uk>

1016 scm_getpeername, scm_recv, scm_send, scm_recvfrom,
1018 use SCM_FPORT_FDES. use SCM_OPFPORTP not SCM_FPORTP.
1020 * posix.c (scm_getgroups): use SCM_ALLOW/DEFER_INTS.
1021 (scm_ttyname): use SCM_FPORT_FDES.
1022 (scm_tcgetpgrp, scm_tcsetpgrp): likewise.
1024 * filesys.c (scm_chown): use SCM_FPORT_FDES.
1025 (scm_chmod, scm_stat, scm_truncate_file: likewise.
1027 * ioext.c (scm_isatty_p): use SCM_FPORT_FDES.
1028 (scm_fdes_to_ports): modified.
1029 (scm_fdopen): use scm_fdes_to_port.
1031 * ports.c (scm_init_ports): don't try to flush ports using
1032 atexit(). it's too late, errors will cause SEGV.
1034 * fports.c (scm_fport_buffer_add): new procedure.
1036 * fports.h (SCM_FDES_RANDOM_P): new macro. use it in
1037 scm_fdes_to_port and scm_redirect_port.
1039 * ioext.c (scm_redirect_port): use setvbuf to set buffers in the
1040 new port. reset fp->random.
1042 * fports.c (scm_fdes_to_port), ports.c (scm_void_port),
1043 filesys.c (scm_opendir):
1044 restore defer interrupts while the port is constructed.
1045 * (scm_setvbuf): if mode is _IOFBF and size is not supplied,
1046 derive buffer size from fdes or use a default.
1047 (scm_fdes_to_port): use setvbuf instead of creating the buffers
1050 vports.c (various places): use SCM_SSTREAM.
1051 strports.c: likewise.
1052 * gdbint.c: likewise.
1053 * ports.h (SCM_SSTREAM): new macro.
1055 * fports.c (scm_input_waiting_p): use scm_return_first, since port

1202 * strop.c (scm_string_capitalize_x): Use the SCM object `s' in

1282 1999-03-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1284 * numbers.c (isfinite): Define this macro if not defined: Return a

1338 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1340 Most of this batch of changes is about how to deal with extended
1341 types when an object system is loaded into Guile. A nice object
1342 system is capable of representing Guile's types as class objects.
1344 For example, we want a regular expression to be of class <regex>.
1345 But regular expressions are smobs which aren't under direct
1346 control of the object system, so there has to be some mechanism
1347 which informs the object system that a new class should be created
1348 which can represent the smob type. I call this a "wrapper class".
1350 * objects.c: #include "smob.h";
1351 (scm_class_keyword): Removed. (Class is automatically created by
1353 (scm_smob_class): Array of smob classes indexed by smobnum.
1354 (scm_make_extended_class): "Plugin" function pointer for creation
1355 of wrapper classes for smob and struct types.
1356 (scm_class_of): Handle compiled closures. (Currently regarded as
1358 Use scm_smob_class to handle smob types;
1359 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
1360 through scm_smob_class;
1363 * smob.c (scm_newsmob): Also create a wrapper class if
1364 scm_smob_class has been initialized.
1366 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
1367 type code and smobnum.
1369 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
1370 (scm_struct_table): Weak key table with auxilliary information for
1371 struct types. Currently used for names and wrapper classes.
1372 (scm_struct_ihashq): Hash function for structs.
1373 (scm_struct_create_handle): Get/create entry in scm_struct_table.
1374 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
1375 for accessing names of vtables. The record implementation in
1376 boot-9.scm currently uses the setter to record the name of record
1377 types. When the object system is initialized, it can use this
1378 information to create wrapper classes with suitable names.
1379 (scm_init_struct): Allocate scm_struct_table.
1380 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
1381 (struct tags are a finite resource and we might want to restrict
1382 the use of tags to vtables only. E.g., Goops only uses tags for
1384 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
1386 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
1389 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
1390 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
1391 Used for access of struct table entries.
1393 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
1394 (scm_hash_fold): New procedure. Used to process all entries in a
1395 hash table (in no particular order).
1397 Argh! For the umpteenth time I got compilation errors because of
1398 the "intuitive" name `kw'. This has to have an end:
1400 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
1401 "kw" --> "keywords" everywhere.
1402 (I doubt that this will cause big compatibility problems since the
1403 application interface is unaffected.)
1405 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
1407 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1409 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
1410 column inums to native form.
1412 Improvement of backtraces: Introduces a new stack narrowing
1413 specifier, #t, for the inner cut. (See further in the comments in

1417 (Used to flag certain system procedures which shouldn't turn up in
1420 * eval.c (scm_sym_system_module): New symbol. (Used to flag
1421 modules which aren't "user" modules and the code of which

1425 Extract the lookup closure from an environment.
1426 (scm_system_module_env_p): New function: Return non-#f if MODULE

1432 * debug.c (scm_procedure_name): Use name property in the default
1435 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
1437 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
1439 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
1440 procedure throughout.
1442 * print.c (scm_iprin1): Removed extraneous space when printing
1443 procedure-with-setters.
1445 Entity and operator setter slots were introduced as a complement
1446 to the <procedure-with-setter> type in order to support entities
1447 and operators with setters in a reasonable and efficient way.
1448 * procs.c (scm_procedure, scm_setter): Handle entity and operator
1451 * objects.h (SCM_OPERATOR_SETTER, SCM_ENTITY_SETTER): New macros.

1463 * objects.h (SCM_OBJ_CLASS_REDEF): New macro: Find class slots
1464 directly through the instance.
1466 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
1468 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
1469 scm_struct_i_flags instead of scm_vtable_index_layout!
1471 * list.c (scm_list_star): New procedure.
1473 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1552 * dynl.c, dynl-dld.c, dynl-dl.c, dynl-shl.c (sysdep_dynl_link,
1553 sysdep_dynl_unlink, sysdep_dynl_func): Arguments FNAME, SUBR, and
1554 SYMB now point to const.
1556 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1558 * print.c (scm_iprin1): Use scm_procedure_name instead of
1559 scm_procedure_property for compiled closures.
1561 * tags.h (scm_tc7_pws): New procedure type. Four representations
1562 for procedure-with-setters were considered before selecting this
1565 1. A closure where the CODE and ENV slots are used to represent
1566 the getter and a new SETTER slot is used for the setter. The
1567 original getter is stored as a `getter' procedure property. For
1568 closure getters, the CODE and ENV slots contains a copy of the
1569 getter's CODE and ENV slots. For subr getters, the CODE contains
1572 2. A compiled closure with a call to the getter in the cclo
1573 procedure. The getter and setter are stored in slots 1 and 2.
1575 3. An entity (i.e. a struct with an associated procedure) with a
1576 call to the getter in the entity procedure and the setter stored
1577 in slot 0. The original getter is stored in slot 1.
1579 4. A new primitive procedure type supported in the evaluator. The
1580 getter and setter are stored in a GETTER and SETTER slot. A call
1581 to this procedure type results in a retrieval of the getter and a
1582 jump back to the correct eval dispatcher.
1584 Representation 4 was selected because of efficiency and
1587 Rep 1 has the advantage that there is zero penalty for closure
1588 getters, but primitive getters will get considerable overhead
1589 because the procedure-with-getter will be a closure which calls
1592 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
1593 <procedure-with-setter>, but together with rep 2 it suffers from a
1594 three level dispatch for non-GOOPS getters:
1596 cclo/struct --> dispatch proc --> getter
1598 This is because the dispatch procedure must take an extra initial
1599 argument (cclo for rep 2, struct for rep 3).
1601 Rep 4 has the single disadvantage that it uses up one tc7 type
1602 code, but the plan for uniform vectors will very likely free tc7
1603 codes, so this is probably no big problem. Also note that the
1604 GETTER and SETTER slots can live directly on the heap, using the
1605 new four-word cells.
1607 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,
1608 SCM_SETTER): New macros.

1627 * evalext.c, evalext.h (scm_m_generalized_set_x): New memoizing
1629 (scm_init_evalext): Call scm_make_gsubr for
1630 scm_m_generalized_set_x.
1632 * eval.c, debug.c, tags.h (SCM_IM_SET_X): Renamed from SCM_IM_SET.
1634 * eval.h: Declare scm_s_set_x, scm_sym_set_x;
1636 * eval.c: Renamed "set" --> "set_x" in various names for
1637 consistency of name correspondence between Scheme and C;
1638 Renamed scm_i_set_x --> scm_sym_set_x and made global.
1639 Renamed s_set_x --> scm_s_set_x and made global.
1641 1999-01-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1643 * random.c (scm_i_random_bignum): Made independent of endianness.

1661 scm_rstate from seed.
1662 (scm_copy_random_state, scm_seed_to_random_state): New functions.
1663 (scm_make_random_state): Removed.
1665 * random.c (scm_make_random_state): Use scm_i_make_rstate().

1669 * random.c: Bugfix: Retrieve and store most significant 32 bits in
1670 different order if the machine is bigendian.

1673 1999-01-11 Roland Orre <mdj@mdj.nada.kth.se>
1675 * sort.c (scm_merge, scm_merge_list_x): Bugfix: Place elements
1676 from first arg before equal elements in second arg in result.
1677 (scm_merge_list_step): Bugfix: Don't presume that arguments in a C
1678 function call are executed in a well defined order.
1680 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
1682 * alloca.c (alloca): Cast value returned by malloc. (Thanks to
1685 1999-01-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1687 * random.c: Removed alloca includes.
1689 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
1691 * Makefile.in: This changed, for some reason I don't really
1692 understand, when I ran automake in the top level directory. This
1693 may be contamination by Cygnus internal releases. If you re-run
1694 automake and this change gets reverted, don't worry about it.
1696 1999-01-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1698 * sort.c, sort.h: New files: Implement slib's and scsh's sort
1699 interfaces. Author: Roland Orre.

1703 * init.c: #include "sort.h";
1704 (scm_boot_guile_1): Call scm_init_sort ().
1706 * numbers.h: Added #include "libguile/print.h".
1708 * numbers.c: Formatted according to Guile conventions;
1709 Renamed s_bignum --> scm_s_bignum.
1711 * random.c, random.h: New files: Random number support.
1712 Interface same as slib's.
1714 * Makefile.am: Added random.c, random.h, random.x.
1716 * init.c: #include "random.h";
1717 (scm_boot_guile_1): Call scm_init_random ().
1719 1998-12-23 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1721 * Makefile.am: New files: guardians.c, guardians.x, guardians.h
1723 * guardians.c, guardians.h (scm_make_guardian,
1724 scm_guardian_gc_init, scm_guardian_zombify, scm_guard,
1725 scm_get_one_zombie, scm_init_guardian): This is an implementation
1726 of guardians as described in R. Kent Dybvig, Carl Bruggeman, and
1727 David Eby (1993) "Guardians in a Generation-Based Garbage
1728 Collector" ACM SIGPLAN Conference on Programming Language Design
1729 and Implementation, June 1993 ftp://ftp.cs.indiana.edu
1730 /pub/scheme-repository/doc/pubs/guardians.ps.gz
1731 Author: Michael N. Livshin.
1733 * gc.h (SCM_MARKEDP, SCM_NMARKEDP): New macros.
1735 * gc.c (scm_igc): Call scm_guardian_gc_init and
1736 scm_guardian_zombify.

1740 1998-12-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1742 * macros.c (scm_makacro, scm_makmacro, scm_makmmacro): Added
1745 1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1747 Move the procedure slots of entities to invisible slots (so that
1748 we can have operator class objects which themselves are entities).
1749 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
1750 SCM_STRUCTF_ENTITY): New constants.
1752 * struct.c (scm_make_struct): Allocate "invisible" room for
1753 procedures if SCM_STRUCTF_ENTITY is set in vtable.
1755 * gc.c (scm_gc_mark): Mark entity procedures.
1757 * struct.c, struct.h (scm_alloc_struct): Renamed from alloc_struct
1759 (scm_struct_init): Renamed from init_struct and made global.

1762 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0,
1763 SCM_ENTITY_PROC_3): Adjusted for new location of procedure slots.
1765 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
1767 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
1768 of syntactic forms, similar to SCM_PROC.
1769 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
1770 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
1771 for the name symbols when needed.
1773 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
1775 * Makefile.in: Regenerated.
1777 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
1779 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
1780 take the address of _into; it might be a register. Just have
1781 scm_debug_newcell return the new cell.
1782 * gc.c (scm_debug_newcell): Just return the new cell, instead of
1783 taking the address of a place to store it as an argument.
1784 * gc.h (scm_debug_newcell): Change declaration.
1785 (Thanks to Greg Harvey.)
1787 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1789 * ramap.c (array-copy-in-order!, array-map-in-order): New names.
1790 Replaces old names serial-array-copy! and serial-array-map!.

1796 * smob.c (freeprint): New function.
1797 (freecell): Use it to print freed objects, for slightly easier
1800 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1802 * backtrace.c (display_frame): Made more robust. Doesn't throw an
1803 error if no source properties can be found for a frame. (Thanks
1804 to Christian Lynbech.)
1806 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1808 * objects.h: Removed slots direct_supers and direct_slots from the
1809 definitions of the rudimentary classes described by objects.h.
1811 * objects.c, objects.h (scm_entity_p): New procedure. Together
1812 with the predicates scm_procedure_p and scm_struct_p, this
1813 predicate makes it possible to differ between structs, entities
1816 * modules.c, modules.h (scm_resolve_module): New function.
1818 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1820 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
1821 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
1824 * objects.c (scm_entity_p): New procedure.
1826 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
1827 for asubrs, rpsubrs, lsubrs and lsubr_2s.
1829 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1831 * procprop.h (scm_i_procedure_arity): Added declaration.
1833 * procprop.c (scm_i_procedure_arity): Made global; New code to
1834 handle operators and entities.
1835 (scm_procedure_property): No need to call scm_procedure_p since
1836 scm_i_procedure_arity now does all necessary type checking.
1837 Added #include "objects.h".
1839 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
1840 s_add_hook_x --> s_remove_hook_x.
1841 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
1842 Added #include "procprop.h"
1844 * feature.c, feature.h (scm_reset_hook_x): New procedure.
1845 (scm_make_hook): Optional argument defines number of arguments to
1847 (scm_make_named_hook): Take number of args as second arg.
1848 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
1849 boot-9.scm for a while); First arg is the hook. The rest are
1850 arguments passed on to the hook procedures.
1852 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
1854 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
1855 scm_logbit_p): Do the computation in ulongs. This is not as nice
1856 as doing it in bignums, but at least it's good enough for
1857 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
1859 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
1860 subexpressions. (Thanks to Charbel Jacquin.)
1862 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
1864 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
1865 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
1866 (scm_make_named_hook): New function.
1868 * feature.c: Added #include "eval.h".
1870 * modules.c (scm_make_module): Beautify the module.
1872 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1874 * modules.c, modules.h: New files: C interface to modules. (This
1875 is necessary in order to interface the object system to Guile
1876 properly. The guts of these modules will be replaced by the new
1877 module system in the future.)
1879 * init.c: Added #include "modules.h"
1880 (scm_boot_guile_1): Call scm_init_modules.
1881 (invoke_main_func): Call scm_post_boot_init_modules.
1883 * Makefile.am: Added modules.c, modules.x, modules.h.
1885 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
1887 * procs.c: #include "objects.h"
1888 (scm_procedure_p): Return #t also on structs which are operators.
1890 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
1891 <operator-metaclass> and <entity-class> to <standard-class>,
1892 <operator-class> and <entity> in order to conform with STKlos
1895 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
1896 which isn't an operator.
1897 (SCM_APPLY): Ditto, but jump to badproc.
1899 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
1901 * eval.c (SCM_CEVAL): Allow structs implanted in code.
1902 Previously, structs implanted in code were interpreted as forms
1903 the operator of which was a gloc. We solve this by checking for
1904 the zero in the emulated vcell in the struct vtable. Since
1905 implanted structs always will look like forms with a gloc
1906 operator, execution will only be slowed down by maximally one
1907 extra test-and-branch per application.
1909 * evalext.c (scm_definedp): Removed check for isyms; Added a
1910 second optional argument: It is now possible to supply an
1911 evaluation environment in which to look for the symbol.
1913 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1915 * readline.c (scm_init_readline): Set
1916 rl_basic_word_break_characters. (Thanks to Ian Grant.)
1918 * coop.c (coop_condition_variable_wait): Removed
1919 (coop_condition_variable_wait_mutex): Folded logic of
1920 coop_mutex_unlock into coop_condition_variable_wait_mutex to
1921 prevent condvar signal lossage. Previously, another thread could
1922 start to run after unlocking the mutex but before putting the
1923 current thread on the wait queue. If that thread then would
1924 signal the first, the signal would be lost. (Thanks to Christian
1927 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1929 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
1932 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1934 * objects.c (scm_i_make_class_object): Renamed from
1935 make_class_object; exported; error checking moved to
1936 scm_make_class_object and scm_make_subclass_object.
1937 (scm_make_class_object, scm_make_subclass_object): Use
1938 scm_i_make_class_object.
1939 (scm_make_subclass_object): Let the subclass have same metaclass
1942 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1944 * debug.c (scm_debug_options): Bugfix: Set the value of
1945 scm_stack_checking_enabled_p after setting debug options;
1946 #include "stackchk.h". (Thanks to Richard Polton.)
1948 1998-11-13 Radey Shouman <rshouman@metro2000.com>
1950 * unif.c (scm_array_contents): removed unnecessary test for 0
1953 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1955 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
1956 Replaced by macro `collect' in boot-9.scm.
1958 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1960 * eval.c (scm_copy_tree): Copy source properties if existent.
1962 * debug.c (scm_start_stack): Copy source when evaluating. (If we
1963 don't, we may end up passing memoized source to a transformer.)
1965 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1967 * stack.c (get_applybody): Help function which lookups the first
1968 body form of the apply closure.
1969 (read_frames): Prevent the source of the first form of the apply
1970 closure from being recorded. This would only be confusing.
1972 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
1973 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
1975 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
1977 * stacks.c (read_frame): Bugfix: Removed lingering `else'
1979 (read_frames): Use SCM_MACROEXPP.
1981 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1983 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
1984 don't contain interesting information since all arguments are
1985 present in the frame which applies the compiled closure anyway.);
1986 Skip the transformer application frames.
1988 * print.c (scm_iprin1): Print gsubrs as primitives.
1990 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1992 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
1994 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
1995 that we can identify these in a backtrace. (This change doesn't
1996 introduce any significant speed penalty.)
1998 * eval.c: Added note about `serial-map' using scm_map.
2000 * read.c, read.h (scm_read_options, scm_read_opts): Removed
2001 readline options. They should reside in their own options array.
2003 * readline.c, readline.h (scm_readline_options,
2004 scm_readline_opts): Moved readline options here.
2006 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2008 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
2009 SCM_ROCHARS instead of SCM_CHARS.
2011 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
2012 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
2014 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2016 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
2017 This is quite important since the latter clears the
2018 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
2019 every single character read...
2021 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2023 * print.c (scm_iprin1): Removed suspect looking (and indeed
2024 malevolent) semicolon after test for user supplied closure print
2025 procedure. (Thanks to Telford Tendys.)
2027 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
2028 (scm_memq, scm_memv, scm_member): Do argument checking *before*
2029 starting to search the list. Removed call to sloppy_mem_check.
2031 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
2032 procedures: Same as scm_delq_x et al, but delete maximally one
2035 * options.c (scm_options, scm_init_options): GC-protect option
2036 values of type SCM. (Thanks to Telford Tendys.)
2038 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2040 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
2041 make sure that there always is a "real" scm_lookupcar.
2043 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2045 * read.c, read.h (scm_read_opts): New read options
2046 "history-length" and "history-file".
2047 (scm_read_options): Stifle history to history length.
2049 * readline.c (scm_read_history, scm_write_history): New procedures.
2051 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2053 * eval.h (scm_macro_eval_x): Removed declaration.
2055 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
2056 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
2057 Renamed and made global.
2059 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
2060 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
2062 * evalext.c, evalext.h: New files. Contain non-R5RS things
2063 having to do with evaluation.
2065 * evalext.c (scm_serial_map): New procedure: Version of `map'
2066 which guarantees that the procedure is applied to the lists in
2068 (scm_m_sequence_to_list): New syntax: Version of `begin' which
2069 returns a list of the results of the body forms instead of the
2070 result of the last body form.
2071 (scm_definedp, scm_m_undefine): Moved from eval.c
2073 * evalext.h (scm_m_sequence_to_list): Added declaration.
2075 * macros.c, macros.h: New files.
2076 (scm_procedure_to_syntax, scm_procedure_to_macro,
2077 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
2078 scm_macro_name, scm_macro_transformer): Moved from eval.c
2079 (scm_make_synt): Moved from eval.c
2081 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
2083 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
2086 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
2088 * debug.c, print.c: Added #include "macros.h".
2090 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2092 This change adds the ability to use `unread-char' multiple times
2093 without interspersed reads and adds the new procedure
2094 `unread-string'. The change is optimized for the common case of
2095 unreading a single character. This is also the reason behind the
2096 choice to store characters in the port itself: in most cases no
2097 extra malloc is required.
2099 The amount of code in some macros in ports.h has been increased to
2100 the extent that they would fit better as C functions, but, since
2101 this code belongs to the port representation, such functions
2102 should be placed in ports.c which would cause calls back and forth
2103 between ports.c and genio.c. That is not good for performance.
2104 Also, keeping them as macros allows the compiler to do some
2105 optimizations which are needed to make the current interface
2106 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
2108 One benchmark (Guile startup time) indicates an increase of
2109 loading speed of 1%. Another (reading (using `read') boot-9.scm
2110 10 times) shows no change in performance.
2112 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
2113 made to find a beautiful solution.)
2115 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
2116 (SCM_TRY_CLRDY): New macro: Only clear the first unread
2117 character. (SCM_CLRDY clears all.)
2118 (SCM_N_READY_CHARS): New macro: Returns number of unread
2119 characters in a port. Returns wrong answer if SCM_CRDYP is false.
2120 (struct scm_port_table): New fields: `entry' contains port table
2121 index, `cp' points to last unread char, `cbuf' is the buffer for
2122 unread chars, `cbufend' points after end of the character buffer.
2124 * ports.h, ports.c (scm_unread_string): New procedure.
2125 (scm_grow_port_cbuf): New function.
2127 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
2129 (scm_generic_fgets), fports.c (local_fgets): Use a loop
2130 to read unread characters. Use SCM_TRY_CLRDY instead of
2133 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
2135 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
2137 * genio.c, genio.h (scm_ungets): New function.
2139 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
2142 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2144 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
2145 declarations. (Thanks to Russ McManus.)
2147 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2149 * numbers.c (num2long): As a software archeologist, I'm proud of
2150 this finding! :) Preliminary dating suggests an almost 4 year old
2151 remnant from the SCM ancestor. The sample has been removed from
2152 the finding site and is now safely stored in the repository.
2154 * numbers.h: Removed prototype for num2long.
2156 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
2158 * gh_data.c (gh_scm2doubles): Make it possible to pass result
2159 array as second arg.
2160 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
2161 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
2162 * gh.h: Updated and added prototypes.
2164 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
2166 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
2168 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
2170 * guile-snarf.in: Never generate an empty file. (Thanks to
2173 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
2174 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
2175 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
2176 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
2177 gh_new_procedure5_0): Specify argument types, to appease C++
2178 compilers. (Thanks to Brad Bowman.)
2180 Bug reports from Russ McManus:
2181 * guile-snarf.in: If the CPP environment variable is set, use that
2182 as the C preprocessor, instead of the preprocessor autoconf
2184 * snarf.h (SCM_PROC): Cast the function pointer passed to
2185 scm_make_gsubr, to satisfy C++.
2187 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2188 Use the handler passed, instead of ignoring it and using
2189 gh_standard_handler. (Thanks to Etienne Bernard.)
2191 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
2193 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
2196 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>

2213 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
2216 * script.c (scm_compile_shell_switches): Define
2217 use-emacs-interface in the root module, so the repl code can see
2218 it. See today's change to top-repl in ice-9/boot-9.scm.
2220 * filesys.c (set_element, get_element): Make sure that `element'
2221 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2222 Boekemeier and Jorgen "forcer" Schaefer.)
2224 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2226 * chars.c (scm_charnames): In ASCII character name table, make
2227 newlines print as #\newline by default, not #\nl.
2229 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2230 alphabetical order. Oh thrills. But it helps me know how far
2231 along in the compilation I am.
2232 * Makefile.in: Regenerated.
2234 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2236 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2237 #bytes(...) to #y(...), and syntax for short vectors from
2238 #short(...) to #h(...). This may seem nutty, but, like the other
2239 uniform vectors, byte vectors and short vectors want to have the
2240 same print and read syntax (and, more basic, want to have read
2241 syntax!). Changing the read syntax to use multiple characters
2242 after the hash sign breaks with the conventions used in R5RS and
2243 the conventions used for the other uniform vectors. It also
2244 introduces complexity in the current reader, both on the C and
2245 Scheme levels. (The Right solution is probably to change the
2246 syntax and prototypes for uniform vectors entirely.)
2248 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
2250 Don't use local_fgets on sockets; ftell doesn't work on sockets.
2251 (Thanks to Jorgen "forcer" Schaefer.)
2252 * ports.h (SCM_NOFTELL): New flag.
2253 * fports.c (local_fgets): If it's set, use the generic fgets.
2254 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
2256 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2258 * script.c (scm_compile_shell_switches): Add handling of -q switch
2259 (inhibit loading of user init file).
2260 (scm_shell_usage): Add usage text for -q switch.
2261 (scm_compile_shell_switches): Always load user init file first if
2262 it is loaded at all.
2264 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
2266 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
2267 and is now broken under NetBSD. I can't fathom what it's trying
2268 to do, so I've replaced it with something that I do understand,
2269 which seems to work, and which isn't broken on NetBSD. "Progress?
2270 You Decide." (Thanks to Perry Metzger.)
2272 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
2273 signed/unsigned comparison.
2275 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
2277 Warning fixes from Greg Harvey:
2278 * unif.c (scm_array_set_x): initializer for pos
2279 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
2280 * struct.c (scm_struct_ref, scm_struct_set_x): Added
2281 initializers for field_type, since EGCS so desparately wants to
2283 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
2284 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
2285 when GUILE_DEBUG is defined.
2286 * dynwind.h (scm_wind_chain): Same.
2287 * ports.h (scm_pt_size, scm_pt_member): Same.
2288 * print.h (scm_current_pstate): Same.
2289 * procs.h (scm_make_cclo): Same.
2291 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
2293 Handle short and long long uniform arrays properly. (Thanks to
2295 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
2296 raeql_1): Add cases for scm_tc7_svect (short vectors) and
2297 scm_tc7_llvect (long long vectors).
2299 Change the way libguile and boot-9.scm are timestamped, to try to
2300 get rid of these spurious mismatch warnings. Now both
2301 libguile/versiondat.h and ice-9/version.scm are generated directly
2302 by the configuration process, rather than having version.scm
2303 generated directly, and libguile/versiondat.h generated by the
2304 Makefile, which is generated by configure. It seems that
2305 sometimes the Makefile would change, but versiondat.h depends on
2306 Makefile.in, not Makefile, so it wouldn't get rebuilt.
2307 * Makefile.am (versiondat.h): Target removed; this is generated
2308 directly by the configure script now.
2309 (BUILT_SOURCES): Remove versiondat.h.
2310 * versiondat.h.in: New file, transformed by the configure script
2312 * Makefile.in: Regenerated.
2314 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
2315 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
2316 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
2317 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2318 if we want to use them in a header file some day, we can. (Thanks
2319 to Michael Livshin.)
2321 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2322 SCM numbers, so we won't have rollover problems; the range of a
2323 signed long in milliseconds is about 25 days. (Thanks to Karl
2326 Don't redefine sleep and usleep; fix this problem now.
2327 * coop.c (sleep, usleep): Remove declarations; we don't use or
2328 redefine these any more.
2329 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2330 job of usleep and sleep in a thread-friendly way. We can use
2331 these in the rest of Guile. Define versions for systems both with
2332 and without iselect.
2333 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2334 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2335 we're just using it, not redefining it, we can use a K&R style
2337 (sleep): Declare this, too, if the system hasn't.
2338 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2339 scm_uthread_sleep if they're available; otherwise, just call the
2341 * scmconfig.h.in: Regenerated.
2343 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2345 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2347 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2349 * threads.c: Doc fix.
2351 The argument type of usleep varies from system to system,
2352 as does the return type. We really shouldn't be redefining usleep
2353 at all, but I don't have time to clean that up before the 1.3.
2354 release. It's on the schedule for afterwards. (Thanks to Julian
2356 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2358 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2359 * scmconfig.h: Regenerated.
2361 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2362 right way to handle system variation. Autoconf's approach is the
2364 * simpos.h (scm_software_type): Declaration deleted.
2366 * script.c (scm_find_executable): Don't test if unix is #defined
2367 here; first, NetBSD doesn't #define it, and second, it's the wrong
2368 way to go about these things. (Thanks to Perry Metzger.)
2369 (dld_find_executable): Delete this MSDOS support code. This isn't
2370 the way we want to support this; it needs to be rethunk at a
2373 * genio.c (scm_do_read_line): Don't just politely check that the
2374 line was either non-empty or EOF. Abort if it's empty and not
2377 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2379 * scmconfig.h.in: Regenerated.
2381 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2384 * genio.c (scm_do_read_line): Count lines correctly when the file
2385 doesn't end in a newline.
2387 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
2389 * genio.c (scm_do_read_line): Maintain the line count correctly.
2390 (Thanks to Harvey J. Stein and Greg Harvey.)
2392 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
2395 * numbers.c (big2str): Protect t from garbage collection until
2396 we're done. (Thanks to Gary Houston.)
2398 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
2400 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
2402 * Makefile.in: Regenerated.
2404 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
2405 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
2408 Do magic to mix reads and writes on stdio FILE-based ports.
2409 (Thanks to Christian Lynbech.)
2410 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
2412 (pre_read, pre_write): New functions.
2413 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
2414 local_fputs): Call them.
2415 (local_fflush): Mark the port as ready for reading and writing.
2416 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
2417 flags on new port objects. This might not be accurate --- who
2418 knows what state the FILE * is in when we get it --- but it won't
2419 do extraneous calls to fflush or fseek, so it's no worse than the
2420 behavior before this change.
2421 * ports.h: Add comment.
2423 Centralize the creation of port objects based on stdio FILE * in
2424 fports.c; don't just throw them together anywhere.
2425 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
2426 what the rest of Guile wants. Don't set the revealed count;
2427 that's only appropriate for stdin, stdout, stderr.
2428 (scm_standard_stream_to_port): This function does set the revealed
2430 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
2431 not scm_stdio_to_port.
2432 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
2433 * fports.c (scm_open_file): Same.
2434 * posix.c (scm_pipe): Same.
2435 * socket.c (scm_sock_fd_to_port): Same.
2436 * ioext.c (scm_fdopen): Same.
2437 (scm_freopen): Moved from here to...
2438 * fports.c (scm_freopen): ... here. This is really something that
2439 munges the internals of an fport, so it should go here.
2440 * fports.h (scm_stdio_to_port): Adjust prototype.
2441 (scm_standard_stream_to_port, scm_freopen): New protoypes.
2442 * ioext.h (scm_freopen): Prototype removed.
2444 * filesys.c (set_element, get_element): This can work on both pipe
2445 and file ports, so use SCM_FPORTP to typecheck, instead of testing
2448 * scmconfig.h.in: Regenerated.
2450 Change the definition of the functions in scm_ptobfuns so that
2451 they get passed the port object, not the port's stream.
2452 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
2453 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
2454 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
2455 Pass the port itself to the scm_ptobs function.
2456 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
2457 scm_generic_fgets): Same.
2458 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
2459 getc_void_port, fgets_void_port, close_void_port): Just change the
2460 argument names; these functions don't really do anything.
2461 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
2462 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
2463 port as an argument, and use SCM_STREAM to get the stdio FILE *.
2464 Also, use prototyped definitions, and get rid of the extra
2466 (scm_fptob, scm_pipob): We don't need casts here any more.
2467 * strports.c (prinstpt): Use prototype declarations.
2468 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
2469 and use SCM_STREAM to get the string info. Also, use prototyped
2470 definitions, and get rid of the extra declarations.
2471 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
2474 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
2475 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
2477 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
2478 scm_fgets, for consistency.
2479 (scm_fptop, scm_pipob): References updated.
2481 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
2483 Include the source location in error messages for scripts.
2484 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
2485 stack is still there when we catch the error.
2486 * throw.c (handler_message): If we are handling an error with a
2487 message, then put together the proper arguments and call
2488 scm_display_error, instead of scm_display_error_message. That
2489 displays source location, if it can find it.
2491 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
2493 * gc.c (scm_unprotect_object): Change this so that calls to
2494 scm_protect_object and scm_unprotect_object nest properly.
2495 (scm_protect_object): Doc fixes.
2497 * strings.c (scm_string_set_x): Require the argument to be a
2498 writable string, not a substring or a symbol.
2499 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
2500 (Thanks to John Redford and Charbel Jacquin.)
2502 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
2504 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
2506 * eval.c (safe_setjmp): Remove this misunderstanding.
2507 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
2510 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
2512 * libguile.h: Mark these as C declarations, for compilation by C++
2515 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
2516 __cplusplus clause. I seriously doubt this ever worked the way
2517 the author seems to have intended.
2519 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
2521 Utterly needless cleanups to hopelessly messy code.
2522 * ports.c: Doc fixes.
2523 (scm_fflush): Moved to ...
2524 * genio.c (scm_fflush): ... here, amongst all the other port
2525 method invocation functions.
2526 * genio.h, ports.h: The prototype moves too.
2528 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
2530 * backtrace.c (display_error_body): The current frame does not
2531 always have a parent frame; consider a function called directly
2532 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
2535 * alloca.c (alloca): Undo yesterday's changes, and simply call
2536 malloc directly for storage, and abort if we don't get what we
2537 want. The situation is much simpler --- just call malloc. Emacs
2538 has bizarre/evil requirements (signal handlers might malloc unless
2539 you set this global flag, so you have to set the flag around all
2540 calls to malloc) which we are certainly not going to conform to,
2541 so we can do the simple and obvious thing.
2543 * coop.c (coop_condition_variable_wait): Make this function
2544 static. It's only useful internally --- you should never just
2545 wait on a condition variable.
2546 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
2548 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2550 * unif.c (scm_array_set_x): Accept any kind of number as an
2551 element for a uniform vector of doubles. This is more consistent
2552 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
2554 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
2555 works; I can't conveniently test it myself. (Thanks to Dvid
2556 Tillman for the bug report.)
2558 * init.c: Doc fixes.
2560 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
2561 from here, not from scm_compile_shell_switches (which is a pretty
2562 dumb place to do it).
2563 (scm_load_startup_files): New function.
2564 (scm_ice_9_already_loaded): Variable moved to here from script.c.
2565 * script.c (scm_compile_shell_switches): Don't load the startup
2567 (scm_ice_9_already_loaded): Variable moved.
2568 * init.c (scm_load_startup_files): Prototype for new function.
2569 * gh_init.c (gh_enter): Doc fix.
2571 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2573 Some anti-warning changes from Greg Harvey.
2574 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
2575 warnings when it doesn't understand our NORETURN declarations in
2577 * posix.c (scm_mknod): Similar.
2579 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2581 * posix.c (scm_getpwuid): If we can't find an entry, return our
2582 own message, instead of using scm_syserror --- the getpwMUMBLE
2583 functions don't set `errno' to anything interesting.
2585 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2587 Get rid of warnings from the cooperative threading system.
2588 * threads.h (scm_single_thread_p, scm_yield,
2589 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
2590 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
2591 scm_wait_condition_variable, scm_signal_condition_variable): Add
2592 prototypes for these Scheme-visible functions.
2593 * coop-defs.h (coop_next_runnable_thread,
2594 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
2595 Prototypes for these here, even though they're from iselect.c.
2596 (coop_condition_variable_wait, coop_join): Add prototypes.
2597 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
2598 scm_threads_free_condvar): Make these smob functions static.
2599 * coop-threads.h (coop_init): Give this a real prototype.
2600 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
2601 (coop_next_runnable_thread): No need to provide prototype; it's in
2604 * scmconfig.h.in: .detarenegeR
2606 * iselect.c, threads.c: Doc fixes.
2608 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2610 * Makefile.in: Regenerated with a patched automake, to get
2611 dependency generation right when using EGCS.
2613 * inet_aton.c (inet_aton): Add prototype, to remove compiler
2614 warning. (Thanks to Robert Pluim.)
2616 * inet_aton.c (inet_aton): Reassure the compiler that the
2617 arguments to the <ctype.h> macros are all unsigned characters, not
2620 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2622 Getting rid of more warnings...
2623 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
2624 today's change to ../configure.in.
2625 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
2626 * scmconfig.h.in: Regenertaded.de.,.__
2627 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
2628 (scm_localtime, scm_mktime): Use a const char * to manipulate the
2631 * readline.c: Doc fix.
2632 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
2633 * readline.h (scm_filename_completion_function): Add prototype.
2634 (scm_init_readline): Make this into a prototype.
2636 * readline.c (scm_filename_completion_function): Use SCM_PROC to
2637 declare this, instead of calling scm_make_subr manually.
2639 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
2641 * readline.h (scm_init_readline): Add prototype for this.
2642 (scm_init_readline): Make this a real prototype.
2644 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
2646 Warning fixes from Maciej Stachowiak:
2647 * backtrace.h (scm_display_application, scm_backtrace): Add
2649 * debug.c (scm_m_start_stack): Make this function static.
2650 * fluids.h (scm_fluid_p): Add prototype.
2651 * procprop.c (scm_i_procedure_arity): Make this function static.
2652 * regex-posix.c (scm_regexp_error_msg): Make this function static.
2653 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
2654 * root.h (scm_dynamic_root): Add external prototype.
2655 * scmsigs.h (scm_usleep): Add external prototype.
2656 * script.h (scm_init_script): Use prototype, not K&R decl.
2657 * stacks.h (scm_stack_id): Add external prototype.
2658 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
2660 1998-09-30 Mark Galassi <rosalia@cygnus.com>
2662 * gh.h: took out the definitions of vset and vref, since they are
2663 replaced by the proper vector routines that correspond to the R4RS
2666 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
2668 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
2669 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
2670 third argument, a C expression that should result in a SCM value,
2671 which is used to initialize the variable. Reimplemented
2672 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
2675 * version.h (scm_libguile_config_stamp): Add prototype.
2676 (From Maciej Stachowiak.)
2678 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
2680 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
2681 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
2683 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
2685 * print.c (scm_iprin1): Rather than having one i, and using it in
2686 several places, declare a fresh i local to each block where it is
2687 used, and give it a signedness appropriate to its use in each case.
2688 (scm_iprlist): Same.
2690 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
2691 comparison warnings.
2693 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
2694 signed/unsigned clashes.
2696 * posix.h (scm_tmpnam): Added prototype.
2698 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
2699 scm_make_subclass_object): Add external prototypes.
2701 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
2702 comparison is okay here.
2704 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
2706 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
2707 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
2709 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
2712 * load.c (swap_port): Make this function static.
2714 * load.c (scm_search_path): Make max_path_len and max_ext_len
2715 unsigned, since they're compared against string sizes.
2717 * load.c (init_build_info): Make i unsigned.
2719 * ioext.h (scm_read_line): Add prototype.
2721 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
2722 scm_hash_fn_remove_x): Make hash bucket index local variable k
2723 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
2724 accurately as possible.
2726 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
2727 comparisons, and range checking to make sure those casts are
2730 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
2731 signed/unsigned comparisons.
2733 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
2734 avoid signed/unsigned comparisons.
2735 * smob.h (scm_numsmob): Change extern declaration to match.
2737 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
2738 avoid signed/unsigned comparisons.
2739 * ports.h (scm_numptob): Change extern declaration to match.
2740 (scm_current_load_port, scm_set_port_line_x,
2741 scm_set_port_column_x): New prototypes.
2743 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
2744 test code, and it causes warnings.
2746 * gh.h (gh_int2scmb, gh_uniform_vector_length,
2747 gh_uniform_vector_ref): Added prototypes.
2749 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
2750 debugging support unconditionally. That's backtrace.c, stack.c,
2751 debug.c, and srcprop.c.
2752 (EXTRA_libguile_la_SOURCES): Omit those from here.
2753 * Makefile.in: Regenerated.
2755 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2757 * options.c (scm_options): Bugfix: Allow empty list of options!
2759 * debug.c, debug.h (scm_single_step): Removed.
2760 (scm_with_traps): New procedure. This procedure could easily be
2761 written in Scheme but needs to be highly optimized.
2763 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
2765 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
2766 Check SCM_TRAPS_P before trapping.
2768 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
2770 Changes to avoid signed/unsigned comparison warnings.
2771 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
2772 (scm_gc_sweep): Make n and j local to the blocks they're used in,
2773 so they can have appropriate types for each application. Make i
2774 signed. Use initializers in some spots. I'll probably pay for
2776 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
2777 (scm_must_realloc): Make nm unsigned.
2778 (init_heap_seg): Make new_seg_index and n_new_objects signed.
2779 (scm_init_storage): Use prototype-style definition, and make the
2781 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
2782 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
2784 * filesys.c (scm_readlink): Make local vars rv and size ints, to
2785 avoid signed/unsigned comparison warnings, and because the return
2786 value of readlink may be -1. Don't bother casting the third
2787 argument to readlink.
2789 * filesys.c (scm_dirname, scm_basename): Move these to their own
2790 page, at the end of the file.
2791 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
2793 * eval.h (scm_eval_options_interface): Add external prototype for this.
2794 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
2796 * eval.c (scm_lookupcar1): Make this static.
2798 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
2799 Make these prototype declarations, not K&R-style.
2801 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
2802 unsigned comparison warning.
2804 * appinit.c: File removed. It had a single function in it, empty,
2805 whose reason for existence is explained in no documentation or
2806 comment. I think it's there as a default for some Tcl-style
2807 initialization, but Tcl abandoned that approach a while ago.
2808 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
2809 (BUILT_SOURCES): Remove appinit.x.
2810 * Makefile.in: Regenerated.
2812 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
2814 * Makefile.in: Regenerated using the last public version of
2815 automake, not the hacked Cygnus version.
2817 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
2819 Remove Totoro kludge.
2820 * Makefile.in, scmconfig.h.in: Regenerated.
2821 * init.c, readline.c: Don't check if TOTORO is #defined.
2823 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
2825 * Makefile.am: Adjust for new thread configuration system.
2826 (INCLUDES): Include the value of THREAD_CPPFLAGS.
2827 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
2829 (THREAD_LIBS): Definition deleted; automake will generate such
2830 things automatically.
2831 * Makefile.in: Regenerated.
2833 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
2835 Simplify smob and port marking; set the mark bit in the generic
2836 marking code, and make marker routines only responsible for
2837 turning up outgoing pointers.
2838 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
2839 before calling the marking function. Don't call the marking
2840 function if it's zero.
2841 * markers.c (scm_mark0): Just return #f. This function isn't
2842 necessary at all now, but it's harmless to call it. We'll leave
2843 it in so other folks' code doesn't croak at link time.
2844 (scm_markcdr): Don't call SCM_SETGC8MARK.
2845 * async.c (mark_async): Don't call SCM_SETGC8MARK.
2846 * dynl.c (mark_dynl_obj): Same.
2847 * root.c (mark_root): Same.
2848 * srcprop.c (marksrcprops): Same.
2849 * unif.c (markra): Same.
2850 * variable.c (scm_markvar): Same.
2851 * ports.c (scm_markstream): Same.
2852 (void_port_ptob): Specify zero for our marking function.
2853 * debug.c (debugobjsmob): Same.
2854 * dynwind.c (guardsmob): Same.
2855 * filesys.c (dir_smob): Same.
2856 * fluids.c (fluid_smob): Same.
2857 * fports.c (scm_fptob, scm_pipob): Same.
2858 * mallocs.c (mallocsmob): Same.
2859 * regex-posix.c (regex_t_smob): Same.
2860 * smob.c (freecell, flob, bigob): Same.
2861 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
2862 * throw.c (jbsmob, lazy_catch_funs): Same.
2864 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2866 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
2867 scm_copy_tree on code in order not to let memoized code to leak
2868 out. Thus, scm_copy_tree needs to copy vectors as well since
2869 quasiquote can introduce evaluated code also inside vector
2872 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2874 * eval.c (scm_copy_tree): Removed ability to copy vectors.
2876 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
2877 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
2880 * unif.c: Say that ivect and uvect are of type signed and unsigned
2881 long instead of int in commentary so that it correctly describes
2884 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2886 * stime.c: Removed declaration of strptime. (It should be
2887 declared by the system headers. If it turns out that some systems
2888 don't, we'll handle that then.) (Thanks to Greg Troxel.)
2890 * stime.h: Renamed TIMEH --> STIMEH
2892 * backtrace.c (scm_display_error, scm_display_backtrace): In order
2893 to increase portability, don't use structure assignment.
2894 (Thanks to Nicolas Neuss.)
2896 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
2898 (finalize_fd_sets): Added empty statement after last case label.
2899 (Thanks to Nicolas Neuss.)
2901 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
2904 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
2906 * init.c, readline.c: OK, I won't have these readline.x bug
2907 reports anymore. We've had them since April. The current reason
2908 is a completely unintelligible failure of totoro.red-bean.com to
2909 do the test for rl_getc_function in libreadline correctly. This
2910 kludge overrides the test if we're on totoro so that the snapshot
2911 generation process can work.
2913 * readline.c: Define a strdup replacement if not existent on system.
2915 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2917 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
2918 This change makes scm_make_vector R5RS compatible. We cannot keep
2919 the third argument since people want to be able to deduce the form
2920 of the C function call only by looking at R5RS. (At the same time
2921 we have removed some unnecessary complexity!)
2923 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
2924 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
2925 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
2926 argument in call to scm_make_vector.
2928 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2930 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
2931 This macro is useful in applications.
2933 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2935 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
2936 (scm_parse_path, scm_search_path): New Scheme level procedures.
2938 * load.h (scm_internal_parse_path, scm_parse_path,
2939 scm_search_path): Declared.
2941 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2943 * filesys.c (dirname, basename): New procedures.
2945 * init.c (scm_boot_guile_1): Removed condition around
2948 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
2949 new data type (guards) for representation of C level guards and
2950 data on the wind chain.
2951 (scm_internal_dynamic_wind): New function.
2953 * dynwind.h: Declare scm_internal_dynamic_wind.
2955 * root.h (scm_root_state): Added scm_cur_loadp.
2957 * root.c (mark_root): Added comment about cur_loadp.
2959 * load.c: #include "dynwind.h";
2960 (scm_primitive_load): Use scm_inner_dynamic_wind to update
2963 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
2965 * ports.c (current-load-port): New procedure.
2967 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2969 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
2970 not a tty, return #f.
2972 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
2973 to Julian Satchell and Roland Kaufmann.)
2975 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
2976 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
2978 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2980 * debug.h, debug.c (scm_start_stack): New function. Implements
2981 the guts of old scm_m_start_stack.
2983 * debug.c (scm_m_start_stack): Use scm_start_stack.
2985 * init.c (scm_start_stack, scm_restart_stack): Renamed to
2986 start_stack and restart_stack. (These have static scope.)
2988 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2990 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
2991 readline functions to come in release 2.3. (Thanks to Chet
2993 (handle_errors): Use the above functions.
2995 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2997 * readline.c: Improvements for readline support: Handle errors
2998 better; Implement before-read-hook.
3000 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3002 * init.c (scm_boot_guile_1), readline.c: Test for
3003 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
3004 assure that we have version >= 2.1.)
3006 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
3008 * readline.c (scm_readline): Defer interrupts while we're calling
3011 * readline.c (scm_add_history): Bugfix: Do strdup before giving
3012 away the string to add_history.
3013 (completion_function): Do completion for readline. (Thanks to
3015 (scm_filename_completion_function): New procedure: Filename
3017 (current_input_getc): New function. Use this one instead of
3018 standard getc from readline.
3020 * throw.c, throw.h (scm_handle_by_throw): New function: This
3021 handler throws errors to next handler on the dynwind chain.
3023 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
3025 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
3028 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3030 * procprop.c (scm_i_procedure_arity): New function. Returns arity
3032 (scm_procedure_properties): Modified to return arity together with
3034 (scm_procedure_property): Added the read-only property `arity'.
3035 (scm_set_procedure_property_x): It is an error to set the `arity'
3038 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
3039 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
3041 * procprop.h (scm_sym_arity): New symbol.
3043 * objects.c (scm_set_object_procedure_x): New procedure: Use this
3044 to set the dispatch procedure of an operator or entity object.
3046 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
3047 Made procedure slots read-only.
3049 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
3050 scm_tcs_cons_gloc case in zero args switch; Fixed args
3051 construction for operators in scm_tcs_cons_gloc case in two args
3054 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3056 * fluids.c: Removed use of assert.h (in order to avoid
3059 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
3061 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
3063 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
3064 change makes the evaluator safer at the cost of evaluation speed.
3065 It handles the case when the user has added a non-immediate
3066 improper end of the application form, e.g., `(+ 0 . x)'.
3067 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
3068 minimize the extra cost as much as possible. The new code is
3069 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
3070 problem with structs planted directly in the code (e.g. by a
3071 macro). This no longer causes segmentation fault. (Thanks to
3074 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
3075 arg `proc' in order to be able to throw errors; New argument
3078 * Removed extra #include "debug.h"
3080 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
3082 * scmsigs.c: Declare usleep as returning void on some systems.
3083 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
3086 * coop.c (usleep): Return void on some systems.
3088 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3090 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
3092 * coop.c: Changed return type of usleep to int.
3094 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
3095 isn't found in the OS.
3097 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
3098 isn't enabled. (Thought that I had made this change ages ago...)
3100 * iselect.c: Declare bzero if not defined by OS.
3102 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3104 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
3105 condition. (Thanks to John Tobey.)
3107 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
3108 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
3111 * __scm.h: Start the long-term project of moving to POSIX threads.
3112 Phase 1: Classification of all critical sections.
3113 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
3114 for A sections. (See comments in __scm.h for details.)
3116 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
3117 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
3119 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3121 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
3122 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
3123 (libpath.h, versiondat.h): Replaced dependency on Makefile with
3124 dependencies on $(srcdir)/Makefile.in
3125 $(top_builddir)/config.status in order to avoid circularity.
3127 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
3128 from argc if argc was 0 initially.
3130 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
3131 in generation of libpath.h.
3133 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
3135 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
3136 libguile from 2 to 3.
3138 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
3140 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
3142 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
3144 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
3145 scm_set_port_column_x, scm_port_filename,
3146 scm_set_port_filename_x): Removed optional arguments. Added
3147 proper argument checking.
3149 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
3150 stack size in machine words.
3152 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
3153 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
3154 to Ole Myren Röhne.)
3156 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
3158 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
3159 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
3161 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
3164 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
3165 procedure apply: Copy argument lists before pushing them unto the
3166 environment so that the environment won't get mutated due to
3167 manipulation of procedure arguments. This should perhaps be
3168 regarded as a temporary solution until someone finds a more
3169 efficient one. (Thanks to Maciej Stachowiak.)
3171 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
3173 * script.c (scm_compile_shell_switches): Use "guile" as default
3174 zero arg if argc is NULL.
3176 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
3178 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
3179 is zero. (Thanks to Dirk Herrmann.)
3181 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
3183 * ports.c (scm_add_to_port_table): First line is now line 0
3184 (was 1). (Interface changed according to suggestion by Per
3187 * backtrace.c (display_header): Add 1 to line and column numbers
3188 when presenting them to the user.
3190 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3191 from debug.c --> eval.c
3193 * eval.h, eval.c (scm_eval_options_interface): New options
3195 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3196 i.e. stacks for new threads.
3198 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3200 * eval.c (unsafe_setjmp): Removed with #if 0.
3202 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3205 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3206 to avoid compiler warnings.
3208 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3210 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3212 * throw.c (handler_message): Print message on current error port
3213 instead of default error port. (Thanks to Maciej Stachowiak.)
3215 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3217 * ports.c (scm_add_to_port_table): allocate in units of
3218 struct scm_port_table *, not struct scm_port_table.
3219 * posix.c (scm_close_pipe): remove the port from the port table
3221 Thanks to Rob Engle for both fixes.
3223 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3225 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3226 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3228 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3230 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3232 * backtrace.c (display_error_body, display_backtrace_body),
3233 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
3234 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
3235 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3236 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
3239 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
3240 don't receive the jmpbuf arg anylonger.
3241 (scm_catch): Don't accept a #f tag.
3242 (scm_throw): Check that key is a symbol.
3243 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
3245 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
3247 * async.c (async_pending): Removed declaration.
3249 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3251 * dynwind.c (scm_wind_chain): New debug function.
3253 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
3254 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
3255 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
3256 extra layer of functions around the body and handler of a thread.
3257 This extra layer makes sure that the handler is called in the
3258 dynamic context of the surround (= empty dynwind list), but under
3259 the *dynamic root* of the body. We can not use the dynamic root
3260 of the surround since that root belongs to another thread => stack
3261 is not handled correctly. It may seem ugly to use this extra
3262 layer, but the extra cost in terms of execution time is really
3263 negligible compared to the total amount of time required to create
3264 a thread, and it would reduce maintainability to duplicate the
3265 crucial and complicated steps performed by cwdr.
3267 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
3268 (SCM_ALLOW_INTS): Added thread switching code before interrupts
3269 get re-enabled. The important effect of this is that interrupts
3270 are blocked during thread switching so that thread data structures
3271 don't risk getting messed up by an unfortunate signal.
3272 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
3273 seems to do more aggressive optimization which actually move
3274 instructions around in these macros in a fatal way. Therefore:
3275 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
3276 just superstitious...)
3277 (SCM_TICK): Maybe do a context switch and take care of asyncs.
3278 This macro should be used instead of SCM_ASYNC_TICK since the
3279 latter doesn't do context switches any more.
3281 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
3282 instead of SCM_ASYNC_TICK.
3284 * coop.c, iselect.c: Since thread switches are now performed with
3285 interrupts masked, we can't use the old mechanism of delivering
3286 signals immediately when they arrive. Signals must instead be
3287 delivered when the asyncs run *after* the end of the critical
3288 section in scm_internal_select. But this also means after context
3289 switch so that the signal will be delivered to a different thread.
3290 To avoid this, I have changed the protocol of
3291 coop_wait_for_runnable_thread and friends so that they are allowed
3292 to return the original thread. So, if a signal arrives during
3293 scm_internal_select, we won't any longer be forced do a context
3294 switch, but can remain in the same thread and deliver the signal
3297 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
3298 scm_asyncs_pending and made it global.
3300 * iselect.c: Small fixes.
3302 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
3303 coop_condition_variable_init, coop_condition_variable_wait,
3304 coop_condition_variable_signal): Changed return type from `void'
3305 to `int'. This is to adhere closer to the pthreads interface.
3306 This, in turn, is part of an attempt to provide C versions of the
3307 mutex and condition variable primitives which can be part of a
3308 frontend to COOP or pthreads.
3310 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
3311 coop_condition_variable_destroy): New functions.
3313 * coop-threads.c (scm_wait_condition_variable): Use
3314 coop_condition_variable_wait_mutex.
3316 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
3317 Definitions moved to coop-defs.h.
3319 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3320 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3321 scm_cond_destroy): New C interface to mutecis and cond vars.
3323 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3325 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3327 * iselect.c: Now several threads can wait on the same file
3328 descriptor. The behaviour is compatible with OS select: All
3329 threads waiting for the fd return with the same status.
3331 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3333 * coop-threads.c, threads.h (scm_spawn_thread): New function.
3334 Can spawn a thread from application C code.
3336 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3338 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3339 gh_doubles2scm): New functions.
3341 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3343 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3344 commented-out version of gh_eval_str()
3346 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3348 * socket.c (scm_bind): free soka after use.
3350 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3352 * stime.c (tzvar): new variable.
3353 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3354 avoid memory leaks when allocating.
3356 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3358 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3361 * gc.c, tags.h: Doc fixes.
3363 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3365 * eval.c (macro-eval!): Removed. This function was a design bug.
3366 It allowed memoized code to leak out to the scheme level. Most
3367 things that you could do with `macro-eval!' can be done with
3370 1997-12-20 Tim Pierce <twp@skepsis.com>
3372 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3373 scm_fgets now depends on ftell(3) to know how many bytes were
3376 1997-12-15 Tim Pierce <twp@skepsis.com>
3378 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3379 dealing with strings.
3381 1997-12-13 Tim Pierce <twp@skepsis.com>
3383 Make %read-line more suitable for implementing read-line efficiently.
3384 * ioext.c (scm_read_line): Strip the terminating newline from a
3385 string, and return a cons of the string and its terminator.
3387 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
3388 of the string that is read is stored in this memory location.
3389 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
3390 * genio.c, genio.h (scm_do_read_line): Update caller.
3391 * ports.h (scm_ptobfuns): Update typedef.
3392 * fports.c (scm_fptob, scm_pipob): Update struct.
3394 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3396 * filesys.c (set_element): Return file descriptor.
3397 (fill_select_type): Return the highest file descriptor.
3398 (scm_select): Tell select about the highest file descriptor. On
3399 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
3400 Therefore the extra overhead for calculating the maximum fd seems
3401 to be more than compensated. Is this correct? In any case,
3402 scm_internal_select will be much faster with this info.
3403 (scm_select, fill_select_type, set_element): Don't accept any kind
3404 of object in the file descriptor list or vector.
3406 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3408 * iselect.c (finalize_fd_sets): Bugfix.
3410 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3412 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
3413 when using scm_internal_select (since we might switch to another
3416 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3418 * simpos.c (scm_system): always define: use sysmissing if not
3419 available. Check for HAVE_SYSTEM instead of _Windows (does
3420 Windows lack system or does it have an unusable one?).
3421 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
3422 Let the argument be optional: if not supplied, call system(NULL).
3424 * ports.c (scm_close_port): relax the type check from OPPORTP to
3425 PORTP; closing a closed port is allowed.
3427 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
3429 * fports.c (scm_fgets): Return if the last char in a chunk is
3430 newline. When fgets returns a string whose length is `size-1', it
3431 is ambiguous whether a whole line was retrieved, so we must check
3432 explicitly whether a line terminator is present.
3434 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3436 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
3437 before taking the CDR. (Thanks to Harald Meland.)
3439 * filesys.c (scm_stat): Slightly optimized.
3441 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
3443 * ports.c (scm_close_port): Make sure the port is open before
3446 * guile-snarf.in: Pass args through to gcc in a way that preserves
3447 whitespace boundaries. (Thanks to Greg Badros.)
3449 1997-12-02 Tim Pierce <twp@skepsis.com>
3451 * stacks.c (scm_frame_procedure): Reverse the logic in the return
3452 statement. (Thanks to Doug Evans for pointing this out.)
3454 1997-12-01 Tim Pierce <twp@skepsis.com>
3456 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
3458 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
3460 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
3461 errno macro expansion of this field name. (errno is a C
3462 preprocessor macro on some systems.)
3464 1997-11-29 Tim Pierce <twp@skepsis.com>
3466 * iselect.c: Doc fix.
3468 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
3470 * init.c (scm_start_stack): Removed initialization of
3471 scm_the_last_stack_var.
3473 * backtrace.h: Declare scm_the_last_stack_var.
3475 * backtrace.c: Define scm_the_last_stack_var.
3477 * root.c (mark_root): Don't mark the_last_stack_var.
3479 * root.h (scm_root_state): Removed the_last_stack_var.
3481 * throw.c: Added #include "fluids.h"
3482 (ss_handler): `the-last-stack' is now a fluid.
3484 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
3485 --> the_last_stack_fluid.
3487 * backtrace.c: Added #include "fluids.h"
3488 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
3489 (scm_backtrace): `the-last-stack' is now a fluid.
3491 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
3492 after scm_init_fluids.
3494 1997-11-28 Tim Pierce <twp@skepsis.com>
3496 * iselect.c: #ifdef USE_THREADS around thread-related includes.
3498 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
3499 DLSYM_ADDS_USCORE to decide whether to add an underscore.
3501 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3503 * iselect.c (coop_next_runnable_thread,
3504 coop_wait_for_runnable_thread): Disable interrupts so that no
3505 async is executed before a potential error_revive.
3506 (scm_internal_select): Disable interrupts during the parts of the
3507 code which manipulate the sleep queue and the file descriptors.
3509 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3511 * Makefile.am: Added iselect.c and iselect.h.
3513 * coop.c (coop_qinit): Initialize fields used by
3514 scm_internal_select.
3515 (coop_qget, coop_qget, coop_tmp_queue): Made global.
3516 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
3517 replacement in iselect.c.
3518 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
3519 coop_join): If GUILE_ISELECT enabled, use
3520 coop_wait_for_runnable_thread instead of
3521 coop_next_runnable_thread.
3522 (usleep, sleep): New replacements for system functions if
3523 GUILE_ISELECT is enabled.
3525 * coop-threads.h: Declare coop_wait_for_runnable_thread.
3527 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
3529 * filesys.c: Added #include "iselect.h". Moved FD-macros to
3530 iselect.h. Implement Scheme level `select' using
3531 scm_internal_select. (See NEWS.)
3533 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
3535 * init.c: Call scm_init_iselect.
3537 * iselect.h, iselect.c: New files. Implements
3538 scm_internal_select. (See NEWS.)
3540 1997-11-27 Tim Pierce <twp@skepsis.com>
3542 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
3543 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
3544 and scm_must_free, since ultimately the string returned will be copied
3545 by scm_makfrom0str anyway. Also, read any characters that may have
3546 been pushed onto the port with scm_ungetc.
3547 * ports.c (scm_generic_fgets): Same as for scm_fgets.
3548 * ioext.c (scm_read_line): Free string after Guilifying it.
3549 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.

3560 gh_repl (argc, argv).
3562 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
3564 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
3565 and to invoke scm_shell().
3566 (gh_launch_pad): took out the loading of boot-9.scm from here,
3567 since it is probably best to let the user control that. In fact,
3568 gh_repl() now invokes scm_shell() which does that.
3570 1997-11-23 Mark Galassi <rosalia@cygnus.com>
3572 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
3575 1997-11-22 Tim Pierce <twp@twp.tezcat.com>

3594 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
3595 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
3597 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
3599 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
3600 configure.in was changed).
3602 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
3604 * Makefile.am (modinclude_HEADERS): Include readline.h here.
3605 * Makefile.in: Regenerated.
3607 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
3609 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
3610 OPORT is an `open' port, not an output port.
3612 * filesys.c (scm_close, set_element, get_element, scm_chown,
3613 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use

3618 scm_set_port_filename_x, scm_port_mode,
3619 scm_close_all_ports_except, scm_set_current_output_port,
3620 scm_set_current_error_port): Likewise
3621 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
3622 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
3624 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
3625 * backtrace.c (display_backtrace_body): Likewise
3626 * fports (scm_setvbuf): Likewise
3627 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,

3634 Minor problems with substring-related tag changes.
3635 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
3636 exactly what we want to leave in to detect substrings.
3637 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
3638 * tags.h: Fix diagrams and comments describing the S tag bit;
3639 remove vestigial remarks about the D tag bit.
3640 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
3641 * strings.c: Formatting tweaks.
3643 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
3644 variable first; then SCHEME_LOAD_PATH, with a warning message.
3645 (scm_parse_path): New function.
3646 * script.c: Doc fixes.
3648 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
3650 Readline support, from Daniel Risacher.
3651 * readline.c, readline.h: New files.
3652 * init.c: #include "readline.h".
3653 (scm_boot_guile_1): Call scm_init_readline, if we have it.
3654 * Makefile.am (libguile_la_SOURCES): Include readline.c.
3655 * Makefile.in: Regenerated.
3656 * scmconfig.h.in: Regenerated, after change to ../configure.
3658 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3660 * gh.h: gh_vector_set -> gh_vector_set_x
3662 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3664 * gh_data.c (gh_vector_set_x): changed name to make it consistent
3665 with the ! -> _x mapping when going from Scheme to C.
3667 1997-10-19 Mark Galassi <rosalia@cygnus.com>
3669 * gh.h (gh_reverse):
3677 (gh_assoc): added these gh_ functions implemented as macros.
3679 * gh_predicates.c (gh_null_p):
3680 (gh_string_equal_p): added these two missing predicates.
3682 * gh_list.c (gh_append):
3687 (gh_set_cdr_x): added these routines as I go through and try to
3688 complete the picture R4RS functions that should be mirrored in the
3691 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3693 * tags.h (scm_tc7_substring): Changed the comment and code to
3694 conform with the changes below. Folks! We have suddenly two new
3695 free tc7 codes!!! Jummy, jummy!
3697 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
3699 * Makefile.in: Rebuilt.

3725 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
3726 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
3728 Don't include "mbstrings.h".
3729 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
3730 (SCM_SYMBOL_SLOTS): Define as 4.

3733 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
3734 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,

3755 1997-10-12 Mark Galassi <rosalia@cygnus.com>
3757 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
3759 * gh_test_c.c (c_vector_test): some improvements on the vector
3762 * gh.h (gh_vector): this used to exist but do the wrong thing.
3763 Now it (almost) does the right thing, though it takes a list
3764 instead of the individual arguments. I need to see how it could
3766 (gh_list_to_vector): added this function as a macro. Corresponds
3767 to Scheme's (list->vector ...).
3768 (gh_vector_to_list): added this function as a macro. Corresponds
3769 to Scheme's (vector->list ...).
3771 * gh_data.c (gh_vector_ref): renamed from gh_vref to
3772 gh_vector_ref, so that it resembles the Scheme routines more.
3773 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
3774 resembles the Scheme routines more.
3775 (gh_make_vector): this used to be (stupidly) called gh_vector().
3776 This is the right name, since it does the same thing as the Scheme
3777 (make-vector ...) procedure.
3779 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
3781 * ports.h: #include "libguile/print.h"

3784 Some indentation fixes.
3786 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
3787 longer a user field; New field: class_flags.
3789 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
3791 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
3793 * gh_data.c (gh_bool2scm): new function which replaces
3794 gh_int2scmb(), which is now tagged as obsolete.
3796 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
3798 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
3799 macros should by convention not test for NIMPness.)
3800 (SCM_COERCE_OPORT): Adjust indentation.
3802 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
3803 SCM_NIMP test before SCM_PRINT_STATE_P.
3805 * struct.c, struct.h, gc.c: Renamed:
3806 scm_struct_i_layout --> scm_vtable_index_layout
3807 scm_struct_i_vcell --> scm_vtable_index_vcell
3808 scm_struct_i_vtable --> scm_vtable_index_vtable
3809 scm_struct_i_printer --> scm_vtable_index_printer
3810 scm_struct_i_vtable_offset --> scm_vtable_offset_user
3812 * struct.c (scm_print_struct): Use new printer slot; Default
3813 printing: Also output hex code of vtable so that type identity
3814 will be indicated as well.
3815 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
3816 Removed struct_printer_var; Removed struct-vtable-offset;
3817 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
3818 vtable-offset-user): New constants.
3820 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
3821 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.

3823 the type represented by this vtable.
3825 * print.c (scm_iprin1): Don't print arguments of macro
3826 transformers. (They are always: exp env.); Bugfix: Unmemoize
3827 transformer source with correct environment.
3829 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
3831 Streamlining of call-with-dynamic-root:
3833 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
3834 there is now only one catch.
3835 (cwdr_outer_body): Removed.
3836 (cwdr_handler): New function.
3837 (scm_internal_cwdr): New function to perform the function of cwdr
3838 but take args that are more useful to C code. Also, the handler
3839 is now invoked *outside* of the new dynamic root, like the docs
3840 say. We no longer have to catch absolutely all errors, the caller
3841 is responsible for using a handler that does not throw, if he
3843 (cwdr): Reimplemented in terms of scm_internal_cwdr.
3844 * root.h (scm_internal_cwdr): New prototype.
3846 Even more but risky streamlining:
3848 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
3849 allocation of the jumpbuf of a root continuation. The changes
3850 below are controlled by it. They are now deactivated.
3851 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
3852 the JMPBUF of the scm_rootcont to NULL before returning.
3854 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
3855 when they are non-NULL.
3856 (scm_gc_mark): Likewise, mark only when non-NULL.
3858 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
3859 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
3861 * gc.c (scm_done_malloc): New function.
3862 gc.h (scm_done_malloc): New prototype.
3864 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.

3871 a certain value is acceptable as a port argument.
3872 (scm_print_state_vtable): New variable.
3873 (scm_free_print_state): Set `revealed' field to false.
3874 (scm_iprin1): Call user supplied closure printer with
3875 scm_printer_apply. Print in the traditional way when there isn't
3876 one or when it returns #f.
3877 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
3878 Accept a port/print-state pair in addition to just a port.
3879 (scm_prin1): Don't return the print_state to the pool when it has
3881 (scm_printer_apply): Set `revealed' field of print_state to true.
3882 (scm_init_print): Set scm_print_state_vtable.
3883 (print_state_fluid, print_state_fluid_num): Removed.
3885 * throw.h (scm_handle_by_proc_catching_all): New prototype
3886 throw.c (scm_handle_by_proc_catching_all): New function
3888 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
3890 * Makefile.in: Regenerated with automake 1.2c.
3892 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
3894 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
3895 was looping endlessly.
3897 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
3899 * strports.c (scm_eval_string): Don't close the port.
3901 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
3902 former returns a nice normal integer. (Thanks to Daniel
3905 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
3907 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
3908 makefile variable as a build parameter called LIBS. The
3909 build-guile program will use this, for the time being.
3910 * Makefile.in: Regenerated.
3912 Thanks to Shiro Kawai:
3913 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
3914 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
3917 * Makefile.in: Regenerated with automake 1.2a.
3919 * script.c (scm_compile_shell_switches): If we hit the -c or --
3920 arguments, don't set the car of (command-line) to scm_usage_name,
3921 the prettified name of the guile executable; give it the full
3922 path, the way shells usually handle $0.
3924 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3926 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
3927 Scheme-level name `array-map' and renamed `serial-array-map' to
3928 `serial-array-map!'.
3930 * backtrace.c: Introduced exception handlers which now enclose
3931 `display-error' and `display-backtrace' so that error reporting
3932 won't get into infinite loops if an error occurs during displaying
3933 of the error. This can very easily happen with user supplied
3934 print call-back routines.
3936 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3938 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
3939 the names `serial-array-map' and `array-map' should be removed.)
3941 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
3943 * init.c (scm_boot_guile_1): Added scm_init_objects ().
3944 Added #include "objects.h"
3946 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
3947 Add #include "feature.h".
3949 * Makefile.am (libguile_la_SOURCES): Added objects.c.
3950 (modinclude_HEADERS): Added objects.h.
3952 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
3953 This test is needed at many places in the code and should be
3954 abstracted. (Motivated by the need of this test in libguiletk.)
3956 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
3957 (scm_eval_string), load.c (scm_primitive_load,
3958 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
3959 Use SCM_EOF_OBJECT_P.
3961 * eval.c (scm_init_eval): Add feature `delay'.
3963 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3965 * scmhob.h: Removed.
3967 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3969 * list.h (SCM_LISTn): New macros. Make list creation in C code
3970 prettier. The idea comes from STk.
3972 * sequences.h, sequences.c, append.h, append.c: Removed. These
3973 files implemented non-R4RS operations which would encourage
3974 non-portable programming style and less easy-to-read code.
3976 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
3979 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
3980 sequences.h, #include append.h.
3982 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and

3987 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
3989 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
3991 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3993 * eval.c: Added #include "objects.h"
3995 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
3998 * smob.c (scm_smob_prehistory): Create two objectsmobs with
3999 adjacent smob numbers.
4001 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4003 * procprop.h: Added declaration of scm_i_inner_name.
4005 * gsubr.c: New global symbol scm_i_inner_name.
4007 * debug.c (scm_procedure_name): Try procedure property
4008 `inner-name' if `name' fails.
4010 * print.c (scm_iprin1): Use scm_macro_name.
4012 * eval.c (scm_m_define): Give names to macros as well; Only the
4013 first top-level definition gives a procedure/macro a name.
4014 Otherwise confusing names can turn up in backtraces.
4015 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
4016 `name'; Give names to macros as well.
4018 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
4019 (scm_macro_transformer): Use SCM_CLOSUREP instead of
4022 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4024 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
4026 (prinmacro): Removed. The code has been moved/merged into print.c
4027 in order to decrease code redundancy. We want macros to print in
4028 a way equivalent to procedures, and it would be silly to duplicate
4029 the required code. (We don't want to maintain two places.)
4030 (macrosmob): Print field is now a NULL pointer.
4032 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
4033 scm_macro_transformer): New prototypes.
4034 (scm_tc16_macro): Declared.
4036 * print.c (scm_iprin1): Added code for printing of macros. Macros
4037 are now printed in a way equivalent to procedures.
4039 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
4041 * procs.h (scm_closure_p): Added declaration.
4043 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4045 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
4046 Shouldn't pass "heap" as the subr name.
4048 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
4050 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
4051 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
4052 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
4053 gh_equal_p): Use SCM_NFALSEP, instead of testing against
4054 SCM_BOOL_T. Any non-false value is true.
4056 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4058 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
4059 scm_gensym): Added prototypes.
4061 * symbols.c (scm_gensym): New function. This will speed up
4062 certain types of applications (such as macro systems) which
4063 generate lots of symbols.
4065 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4067 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
4069 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
4071 * unif.c (scm_shap2ra): tighten the checking of the array dimension
4072 specifier, since (2) or (2 . 3) would cause SEGV.
4073 (scm_transpose_array): more argument checking fixes.
4075 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
4077 * Makefile.in: Regenerated.
4079 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
4081 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
4083 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4085 * error.c, error.h (scm_error_callback): Removed (see NEWS).
4087 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
4089 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
4090 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
4093 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
4094 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
4095 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
4096 scm_array_p, scm_array_rank, scm_array_dimensions,
4097 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
4098 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
4099 scm_array_prototype): Added case scm_tc7_wvect.
4101 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
4103 * errno.h: prototype for scm_strerror.
4104 * error.c (scm_strerror): new procedure.
4106 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4108 * list.c (scm_list_append_x): Allow non-pair as last argument.
4109 This is consistent with the R4RS append and is probably the
4110 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
4112 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4114 * stime.h: prototype for scm_times.
4115 * stime.c (scm_times): new procedure.
4116 * ioext.c (scm_fseek): if the first argument is a file descriptor
4118 (scm_ftell): if the first argument is a file descriptor call lseek
4120 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
4121 * filesys.c (scm_chmod): if the first argument is a file descriptor,
4123 (scm_chown): if the first argument is a port or file descriptor,
4125 (scm_truncate_file): new procedure.
4126 Add DEFER/ALLOW INTS to a few other procedures.
4127 (scm_fsync): new procedure.
4128 (scm_open_fdes): new procedure.
4129 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
4131 (scm_fcntl): the first argument can now be a file descriptor. The
4132 third argument is now optional.
4134 * posix.c (scm_execl, scm_execlp): make the filename argument
4135 compulsory, since omitting it causes SEGV.
4136 (scm_sync): return unspecified instead of #f.
4137 (scm_execle): new procedure.
4138 (environ_list_to_c): new procedure.
4139 (scm_environ): use environ_list_to_c. disable interrupts.
4140 (scm_convert_exec_args): take pos and subr arguments and
4141 improve error checking.
4143 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4145 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
4146 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
4147 argument to SCM_ASSERT. Furthermore, the name of the function
4148 should be passed as first argument when signalling
4149 SCM_WNA. (Thanks to Thomas Morgan)
4151 * gsubr.c (scm_gsubr_apply): From Radey Shouman
4152 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
4153 dispatches on the number of actual args has a default case
4154 reporting an internal error. This is a vestige from a version
4155 that mallocated a SCM vector to hold the arguments. In the
4156 current version this check is too late: if it ever happens we will
4157 have already overstepped the bounds of the array.
4159 Also, the patch [...] adds a check for too many actual arguments."
4161 mdj: Removed check for "internal programming error".
4163 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4165 * gh_io.c (gh_write): New function.
4167 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
4168 throw.c (scm_internal_stack_catch): New sibling to the other catch
4169 functions. Code moved from gh_eval.c.
4170 throw.h: Added header.
4171 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
4172 scm_internal_stack_catch.
4174 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4176 * ioext.h: fix up prototypes.
4177 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
4178 Scheme name is now dup->fdes.
4179 (scm_dup_to_fdes): make the second argument optional and
4180 fold in the functionality of scm_primitive_dup.
4181 (scm_primitive_dup): deleted.
4183 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
4185 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
4186 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
4187 ultrix are defined. Use setvbuf instead of setbuf.
4188 (scm_setvbuf): new procedure.
4189 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
4190 (scm_setfileno): moved from ioext.c.
4191 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
4192 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.

4196 * fluids.c (scm_fluid_p): New function.
4197 * fluids.h (scm_fluid_p): New prototype.

4201 * print.c (scm_iprin1): Enter printed structures into the print
4202 state as nested data while they are printed.
4203 (print_state_fluid, print_state_fluid_num): New variables.
4204 (scm_init_print): Initialize them.
4205 (scm_iprin): If print_state_fluid carries a print_state, use that
4206 instead of creating a new one.
4207 (scm_printer_apply, apply_stub, struct apply_data): New
4208 definitions to help with calling printer functions written in
4210 * print.h (scm_printer_apply): New prototype.
4212 * struct.c (scm_print_struct): Use scm_printer_apply to call the

4223 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
4224 SCM_ASSERT: arg comes before pos.
4226 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4228 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
4229 to a list of length zero correctly.
4231 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

4247 * ioext.h: removed scm_duplicate_port prototype.
4249 * ioext.c (scm_primitive_dup2): return the new file descriptor
4250 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
4252 (scm_fdopen): bug fix: don't try to make port unbuffered until its
4253 stream has been set.
4254 (scm_duplicate_port): deleted, there's now an implementation in
4256 (scm_primitive_dup2): do nothing if newfd == oldfd.
4258 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
4260 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the

4266 * fluids.c (next_fluid_num): don't do
4267 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
4269 * ports.h: prototypes too.
4270 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
4272 * fports.h: prototype too.
4273 * fports.c (scm_evict_ports): moved from ioext.c.
4275 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
4277 * ports.c (scm_close_port): return a boolean instead of unspecified.
4278 throw an error if an error other than EBADF occurs.
4280 * filesys.h: scm_close prototype.
4281 * filesys.c (scm_close): new procedure, can close file descriptors
4282 and ports (scsh compatible).
4284 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
4287 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
4289 * fluids.c, fluid.h: New files.
4290 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
4291 (modinclude_HEADERS): Added "fluids.h"

4300 (scm_make_root): Call scm_copy_fluids to make fluid bindings
4301 unique for the new root when it has a parent.
4303 * smob.h: Include "libguile/print.h" to make scm_print_state
4306 * dynl.c (free_dynl_obj): New function to free the dynamic object
4307 data. (dynl_smob): Use it.
4308 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
4309 the dynamic object data below the linking of the object to avoid
4310 memory leak when the linking code throws an error. Now the code
4311 leaks a whole dynamically linked library when must_malloc throws,
4312 but that should be much less likely.
4314 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
4316 Changes to compile under gnu-win32, from Marcus Daniels:

4318 (scm_localtime): Change SCM_EOF to SCM_EOL.
4319 (scm_mktime): Likewise.

4332 (scm_setpwent): For setpwent.
4333 (scm_setegid): For setegid.
4334 * net_db.c (scm_inet_netof): Don't include unless support

4350 scm_misc_error, not SCM_EOF.
4352 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
4353 arguments for formatting the error message, not SCM_BOOL_F. I
4354 think this is left over from the (eq? '() #f) days.
4356 * read.c (recsexpr): Give this a dummy definition if
4357 DEBUG_EXTENSIONS isn't #defined.
4359 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
4361 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

4371 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
4372 alloca.lo will be included in @LIBLOBJS@. Something better than
4373 this should be possible.
4374 * Makefile.in: Regenerated.
4376 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4378 * simpos.h: prototype for scm_primitive_exit.
4379 * simpos.c (scm_primitive_exit): new procedure, terminates the

4384 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
4385 argument and logior its components together, so the user doesn't
4386 have to do this explicitly. Also, if regexp/basic is supplied, then
4387 turn off REG_EXTENDED.
4388 (scm_init_regex_posix): New regexp/basic symbol.
4389 (REG_BASIC): #define this if it is not already present.

4405 * Makefile.in: Regenerated.
4407 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
4408 flag; I don't think we support it.
4409 (scm_make_regexp): Make sure the user doesn't pass the
4412 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
4414 (scm_init_regex_posix): Define constants for the REG_mumble flags;

4424 (versiondat.h): Print a message, but don't print all the commands.
4425 * load.c: #include "alist.h".
4426 (init_build_info): New function.
4427 (scm_init_load): Call it.

4432 * root.c: Establish a reliable catch-all handler for the new root.
4433 After all the Scheme handler function might signal an error too,
4434 and we don't want to lose that.
4435 (cwdr_inner_body): Renamed from cwdr_body.
4436 (cwdr_outer_body): New function, to establish the user's handler,
4437 and pass control to cwdr_inner_body.
4438 (cwdr): Establish the reliable catch-all handler here, and pass
4439 control to cwdr_outer_body.
4440 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
4441 the user's handler through to cwdr_outer_body.

4448 across this. Only works on GCC. Otherwise, we hope for the best.
4449 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
4450 the feeling that real thread systems will not need this...
4452 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
4454 Try to detect when people are using one version of libguile and a

4466 primitive definitions under their Scheme names.
4468 * Makefile.am (libguile_la_LDFLAGS): Update library version to
4469 1:2. Helps avoid confusion between installed and uninstalled libs.
4471 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
4474 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
4475 backslash from definition; this should be used like: GDB_INTERFACE;
4477 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4479 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
4480 new port unbuffered until its stream has been set.
4482 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
4484 * ports.h: new prototype.
4485 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
4487 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
4489 Make things compile neatly under Sun's C compiler.
4490 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
4491 * extchrs.c (xmbtowc): Make the second arg a normal char, not
4492 unsigned, because that's what the ANSI function takes.
4493 * extchrs.h (xmbtowc): Corresponding change to prototype.
4494 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
4496 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
4497 argument plain char *.
4498 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
4500 * tag.c (scm_tag): Remove unreachable statement.
4501 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
4502 top of the word, it should be unsigned.
4504 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
4505 is defined, to avoid warnings; it's only used in the
4506 conflict-checking code. Which might go away anyway.
4507 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
4508 conditionals; put the label definition in an #if too, to stifle
4511 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
4512 ChangeLog-threads in the distribution.
4513 * Makefile.in: Regenerated.
4515 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4517 * guile-snarf.in: Changed regexp to support CPPs that insert
4518 whitespace between lexical tokens (which munges the `%%%' snarf
4521 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4523 * load.c (scm_init_load_path): Append $(datadir)/guile to
4524 %load-path, so modules do not have to be installed in Guile's
4525 current version directory.
4527 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
4529 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
4530 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
4531 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
4532 call the sysdep functions with deferred ints.
4533 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
4534 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
4535 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
4538 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
4541 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
4543 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
4545 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
4547 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
4550 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
4552 * eval.c (scm_lookupcar1): New procedure to cope with a race
4553 condition during lookup (when using threads).
4554 (scm_lookupcar): Implement in terms of scm_lookupcar1.
4555 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
4558 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
4560 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
4561 supplied. (Change from Tim Pierce.)
4563 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
4565 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
4566 23:47:01 1997" changelog: Slots are now initialized with `#f' by
4567 default and not `()'. `#f' is the canonical non-value in Scheme,
4570 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4572 * struct.c (struct_printer): New variable that holds a handle on
4573 the Scheme variable *struct-printer*. This variable can be set by
4574 Scheme code to override the printing of structures.
4575 (scm_print_struct): If struct_printer is set, call it. If it is
4576 not set, or returns #f, print the structure in the old fashion.
4577 Include "eval.h" for scm_apply.
4579 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
4581 * struct.c (scm_struct_ref, scm_struct_set_x): Use
4582 scm_struct_i_n_words to get the number of fields, not
4583 -scm_struct_n_extra_words.
4585 On the route to fancier struct printing:
4586 * struct.c (scm_print_struct): New function to print a structure.
4587 Include "genio.h" to support it. This function doesn't do
4588 anything interesting right now, but I think it should be here
4590 * struct.h: Include "print.h" and add prototype for
4592 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
4593 print structures ourself.
4595 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4597 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
4598 before applying the handler in case it doesn't return.
4600 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
4602 * scmsigs.h, async.h: updated.
4604 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
4607 * posix.c (scm_uname): interpret only negative values as an error.
4608 Solaris normally returns a positive value.
4610 * script.c (scm_compile_shell_switches): if we are not going into
4611 an interactive repl, set scm_mask_ints to zero so that asyncs can
4614 * simpos.c (scm_system): don't ignore/unignore signals around
4617 * posix.c (scm_open_pipe): don't ignore/unignore signals around
4620 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
4621 done in boot-9.scm instead.
4623 * scmsigs.c, async.c: Major rewriting of signal handling code.
4624 (scm_sigaction): new procedure.
4625 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
4627 (scm_raise): return unspecified, throw error on failure.
4629 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4631 * regex-posix.c (scm_init_regex_posix): Register the "regex"
4632 feature, to help boot-9.scm decide whether to import the regex
4635 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
4637 * eval.c: Include scmconfig.h at the beginning of the file so that
4638 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
4641 * regex-posix.c: #include "_scm.h" before conditionally #including
4642 <regex.h>; the former defines HAVE_REGCOMP.
4644 * regex-posix.c: #include <regex.h> conditionally, so the file is
4645 CPP'able (for dependency scanning) even on systems that don't have
4648 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
4650 Add new R4RS-compliant syntax for keywords.
4651 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
4652 regardless of the setting of the `keywords' read option.
4653 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
4654 can be re-read no matter what the setting of the `keywords' read
4657 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
4659 Add support for POSIX regular expressions.
4661 * regex-posix.c, regex-posix.h: New files. (Some code
4662 is taken liberally from rx/rgx.c in the old Guile dist.)
4664 * init.c: Include regex-posix.h.
4665 (scm_boot_guile_1): Call scm_init_regex_posix.
4667 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
4668 Add regex-posix.[ch] sources.
4669 * Makefile.in: Regenerated.
4671 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
4672 to do this automatically? It didn't for me, bleh.)
4674 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
4676 * fports.c (print_pipe_port): New function.
4677 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
4678 latter doesn't even take the right arguments.
4680 * Makefile.am: Increment shared lib revision number. I think
4681 sometimes the uninstalled Guile finds the installed shared lib;
4682 Gord says doing this might help. As things turned out, I can't
4683 say whether it does.
4684 * Makefile.in: Regenerated.
4686 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
4687 passing it as the closure argument to scm_boot_guile. (Bill
4690 * ports.c (print_void_port, putc_void_port, puts_void_port,
4691 write_void_port, flush_void_port, getc_void_port, close_void_port,
4692 noop0): Use ANSI prototypes instead of K&R declarations, so the
4693 initialization of void_port_ptob gets aggressively type-checked.
4694 Fix arguments of print_void_port and write_void_port. (Bill

4728 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
4730 * script.c (scm_find_executable): Use prototype-style definition
4731 here; apparently it's not quite right to have const in a prototype
4732 and then use a K&R declaration. I wonder if stuff like this will
4733 go away if we compile with -Wrequire-prototypes, or whatever that
4734 is... (Bernard URBAN)
4736 * scmhob.h: New text from Bernard URBAN.
4738 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4740 * script.c: Don't #define const on hpux. Configure takes care of
4741 this. (Thanks to Larry Schwimmer.)
4743 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
4744 decide whether to #include <unistd.h>, instead of listing a bunch
4745 of systems. Don't #include stdio twice. Removed dyked-out
4746 definition of scm_find_impl_file.
4748 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
4750 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
4751 library version info to 1:0.

4758 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
4759 throw.c: Update copyright years; these files have been worked on
4760 significantly in 1997, but only had copyright years for 1996.
4761 Also, change name of copyright holder on some from Mikael
4762 Djurfeldt to Free Software Foundation; he has signed papers
4763 assigning the changes to the FSF.
4765 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
4766 reason not to give the user the option.
4768 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
4769 Return #f on end-of-file when scanning table (i.e. when called
4770 with no arguments). Try to catch errors, when we can.
4771 * posix.c (scm_getgrgid, scm_getpwuid): Same.
4773 * script.h (scm_shell_usage, scm_compile_shell_switches): New
4774 external declarations. These are useful.
4776 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
4778 * posix.c: don't include <sys/select.h> or define macros for
4779 select, since they were not used in this file.
4781 * filesys.c (scm_select): make the fifth parameter microseconds,
4782 not milliseconds. let the fourth parameter be either a real value
4783 or an integer or #f. The first, second and third arguments can
4784 now be vectors: the type of the corresponding return set will be
4786 (set_element, get_element): new static procedures.
4788 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
4790 * strports.c (scm_eval_string): New function.
4791 (scm_eval_0str): Trivially re-implemented in terms of
4793 * strports.h (scm_eval_string): New extern decl.
4795 * net_db.c (h_errno): Add extern decl for this.
4797 * fports.c (local_pclose): New function.
4798 (scm_pipob): Use it in the initializer here.
4801 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
4802 Use a meaningful error message when signalling an error. For
4803 this, scm_gethost must check h_errno rather than errno.
4805 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
4807 * Makefile.in: Regenerated, using automake-1.1p.
4809 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
4811 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
4812 not SCM_UNSPECIFIED.
4814 * script.c (scm_compile_shell_switches): don't append (quit) if
4816 (scm_shell): call scm_exit_status and exit on the result of the
4819 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
4821 Ensure that shared substrings are handled properly when passed to
4822 a system call or other foreign function. Many thanks to Tim
4824 * symbols.h (SCM_COERCE_SUBSTR): new macro.
4825 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
4826 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
4827 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

4842 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
4844 * error.c (scm_error): Add newline to error message.
4846 * init.c (scm_init_standard_ports): Doc fix.
4848 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4850 * dynl-shl.c: Completely replaced with new code from Bernard
4853 * script.c (scm_ice_9_already_loaded): New variable.
4854 (scm_compile_shell_switches): Use it.
4856 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4858 * filesys.c (scm_input_waiting_p): add missing third argument to

4862 calling gmtime in case they share a buffer.
4863 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
4866 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
4868 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
4870 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
4872 * Makefile.am (check-local): New target, which causes 'make check'
4873 to run gh_test_c and gh_test_repl, with some trivial input.
4874 * Makefile.in: Rgnrtd.
4876 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
4878 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
4881 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
4883 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
4884 sure how this was supposed to work.
4885 (scm_async_click): don't send SCM_TICK_SIGNAL.
4886 (scm_init_async): don't initialize %tick-thunk.
4888 * the following change doesn't affect the Scheme interface:
4889 gc-thunk is called at the end of garbage collection. however it's
4890 no longer implemented by pretending it's a signal.
4892 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
4893 system async corresponding to scm_gc_thunk.
4894 * async.h: declare scm_gc_async.
4895 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
4896 gc-thunk directly, instead of going through a signal handler.
4897 (scm_gc_async): new variable, points to the GC system-async.
4898 (scm_init_async): save the GC async as scm_gc_async instead
4899 of using system_signal_asyncs.
4900 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
4902 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>

4905 Don't screw up if we're interrupted.
4906 * Makefile.in: Regeneradet.
4908 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
4910 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
4912 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
4913 we're not using AM_INIT_GUILE_MODULE any more.
4914 * Makefile.in: Reneregated.
4916 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>

4922 Get 'make dist' to work again.
4923 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
4924 * Makefile.in: Regenerated, like a surry without a fringe on top.
4926 Changes for reduced Guile distribution: one configure script,
4928 * configure.in, configure: Removed.
4929 * acconfig.h, acinclude.m4: Moved to parent directory, where the
4930 real configure script lives.
4931 * Makefile.in, scmconfig.h.in: Regenerated.
4933 * init.c: #include "script.h", to get prototype for script.c's
4936 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
4938 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
4939 scm_must_malloc, not raw malloc.
4941 * script.c (scm_compile_shell_switches): Dyke out debugging output
4944 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4946 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
4948 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
4949 system has them. Hope this is safe. Previously
4950 sys/timeb.h was included if HAVE_FTIME was defined or if
4951 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
4952 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
4954 * ioext.c (scm_setfileno): add missing third argument to
4955 scm_misc_error call.
4957 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
4959 * eq.c (scm_equal_p): Correctly compare strings of different
4960 varieties. (Thanks to Tim Pierce.)
4962 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
4964 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
4965 #! block comment must occur on a line all by itself.
4967 Move most of the guts of shell command processing into libguile,
4968 so guile.c can be very small (and eventuallly auto-generated. (I
4969 mean, generated mechanically, not self-generated. Hmm.))
4970 * guile.c, script.c, script.h: New source files.
4971 * init.c (scm_boot_guile_1): Call scm_init_script.
4972 * libguile.h: #include "script.h".
4973 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
4974 targets, for new executable.
4975 (libguile_la_SOURCES): Mention script.c.
4976 (modinclude_HEADERS): Add script.h.
4977 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
4978 not dynamic linking is enabled. This is because we're generating
4979 executables now. Move CY_AC_WITH_THREADS call after those, so the
4980 values of cy_cv_threads_libs captures the libs chosen above.
4981 * Makefile.in, configure, aclocal.m4: Regenerated.
4983 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
4984 We don't maintain this interface any more, and it just confuses
4987 * alloca.c: #include <scmconfig.h>, not <config.h>.
4988 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
4989 it'll get included in disties.
4991 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
4993 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
4994 be distributed, because they confuse people.
4995 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
4997 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
4999 * configure.in: check for presence of gethostent (not present on
5000 OpenBSD by default).
5001 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
5002 * configure, scmconfig.h.in: Regenerated.
5004 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5006 * backtrace.c (scm_backtrace): Split message string across
5007 newlines properly. GCC is more tolerant of this than other
5010 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
5012 Merge threads directory into libguile.
5013 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
5014 threads.h: New source files.
5015 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
5016 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
5018 (modinclude_HEADERS): Add threads.h, coop-defs.h.
5019 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5020 coop-threads.c.cygnus, coop-threads.h.cygnus.
5021 * configure.in: If we're using threads, include threads.o in
5023 * _scm.h, libguile.h: threads.h lives in this directory now.
5024 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5025 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
5026 currently used, but brought along for information's sake.
5027 * ChangeLog-threads: log from old 'threads' directory.
5028 * Makefile.in, configure: Rebuilt.
5030 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
5032 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
5035 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
5037 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
5039 Merge GH interface library into libguile.
5040 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
5041 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
5042 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
5043 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
5045 (EXTRA_libguile_la_SOURCES): ... here.
5046 (pkginclude_HEADERS): Add variable, to get gh.h installed.
5047 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
5048 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
5049 New variables, describing how to build the gh test programs.
5050 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
5051 build the test programs, and we probably should have been linking
5052 libguile.la against them all along, to support AIX shared libs.
5053 Add cflags for threads to CFLAGS; add libs for threads to new
5054 variable THREAD_LIBS, used in Makefile.am.
5055 * ChangeLog-gh: log from old `gh' subdirectory.
5056 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
5058 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
5060 * acconfig.h: Undo change of Apr 9; including the definition of
5061 PACKAGE in the guile headers conflicts with applications' own
5063 * scmconfig.h.in: Regenerated.
5065 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

5072 when PROC is receiving no arguments.
5074 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
5076 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
5077 have S_IFSOCK. This is the case under Ultrix.
5079 * posix.c (scm_status_exit_val, scm_status_exit_val,
5080 scm_status_term_sig, scm_status_stop_sig): Modified to work with
5081 Ultrix versions of WIFSTOPPED, etc., which assume that their
5082 arguments are lvalues (hmm).
5084 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5086 * eval.c: Doc fixes.
5088 * throw.c: Doc fixes; rearranged.
5090 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
5092 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
5094 * acconfig.h: Added entry for PACKAGE.
5095 * scmconfig.h.in: Regenerated.
5097 Changes to work with automake-1.1n, which has better libtool support.
5098 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5099 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
5101 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
5103 * Makefile.in: Rebuild.
5105 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5107 * stime.c (scm_mktime): take an optional zone argument.
5108 (scm_localtime): check putenv return value.
5109 (scm_strftime, scm_strptime): moved from posix.c. move #include
5111 stime.h, posix.h: update prototypes.
5112 (bdtime2c, setzone, restorezone): new static procedures.
5113 (scm_mktime, scm_strftime): use them.
5114 (scm_strftime): don't call mktime before strftime. Use
5115 filltime for return value.
5116 (filltime): convert NULL zname to #f.
5117 (scm_strptime): return a count of characters consumed, not
5118 the remaining string.
5120 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5122 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
5123 (scm_mktime): likewise.
5125 Uncomment localtime and mktime.
5127 * configure.in: add AC_STRUCT_TIMEZONE.
5129 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5131 * stime.c (scm_init_stime): don't define ticks/sec.
5132 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5133 return value problem and is still portable.)
5135 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5137 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
5138 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5139 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
5140 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
5141 cpp_err_symbols.c): Corresponding changes.
5142 * Makefile.in: Regenerated.
5144 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5146 * posix.c (scm_putenv): don't check HAVE_PUTENV.
5147 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
5148 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
5149 * putenv.c: new file, from sh-utils 1.12.
5151 * posix.c (scm_environ): use malloc in place of scm_must_malloc
5152 since allocation isn't for Scheme objects.
5153 (scm_putenv): copy strings before placing in the environment.
5155 * stime.c (scm_current_time): throw an error if time returns -1,
5156 instead of returning #f.
5157 (scm_get_internal_real_time, scm_get_internal_real_time): use
5158 scm_long2num for return value instead of SCM_MAKINUM.
5160 * stime.h: prototypes updated.
5162 * stime.c (scm_time_in_msec): apparently unused, deleted.
5164 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5166 * configure.in: check for gettimeofday.
5168 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
5169 which may be more usefully portable than a gettimeofday interface.
5171 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
5173 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
5175 * Makefile.in: Regenerated.
5177 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5179 * stime.c (filltime): recovered static procedure.
5180 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
5183 * posix.h: add prototype for scm_close_pipe, remove prototypes for
5184 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5186 * posix.c (scm_mknod): split the mode argument into type and perms
5187 arguments, like the extra fields returned by stat.
5189 * fports.c (scm_pipob): set the close, free and print procedures.
5190 (scm_close_pipe): new procedure.
5192 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5193 define them in boot-9.scm
5195 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5197 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5198 wan't defined. Don't include fd.h.
5200 * Previously fd.h was regenerated whenever configure was run,
5201 forcing a couple of files to be recompiled.
5203 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5204 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5205 Check for _fileno as well as _file.
5207 * ioext.c: don't fd.h.
5208 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5211 * Change the stratigy for getting information about errno
5212 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5213 generating lists of symbols during the build process, which will
5214 not always work, include comprehensive lists in the distribution.
5215 To help keep the lists up to date, the "check_signals" and
5216 "check_errnos" make targets can be used.
5218 * configure.in: don't check for a command to extract errno codes.
5219 * Makefile.am: update file lists, remove errnos.list and errnos.c
5220 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5221 check_errnos targets.
5222 (CLEANFILES): remove errnos.c and errnos.list, add
5223 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
5224 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
5225 * errnos.default: deleted.
5226 * cpp_signal.c: new file.
5227 * cpp_errno.c: renamed from errnos_get.c.
5228 * cpp_err_symbols, cpp_sig_symbols: new files.
5229 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
5230 * error.c (scm_init_error): #include cpp_err_symbols instead of
5232 * posix.c (scm_init_posix): don't intern signal symbols. #include
5235 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5237 * strop.c (scm_i_index): allow the lower bound to be equal to the
5238 length of the string, so a null string doesn't always give an error.
5240 * posix.h: new prototypes.
5241 * posix.c (scm_status_exit_val, scm_status_term_sig,
5242 scm_status_stop_sig): new functions, as in scsh. They break down
5243 process status values as returned by waitpid.
5245 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
5247 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
5248 configure doesn't know about it.
5250 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5252 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
5254 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
5255 which defines C variables with global linkage.
5257 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5259 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
5262 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
5264 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
5265 has time to check why this doesn't work well with continuations.
5267 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
5269 * Fix shell syntax error; some shells won't tolerate
5270 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
5272 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5274 * posix.c (scm_uname): throw an error if uname fails instead
5277 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
5279 * error.c (err_head, scm_errno, scm_perror): obsolete procedures

5286 * acconfig.h: Removed PACKAGE.
5288 * scmconfig.h.in: Regenerated.
5290 * snarf.h: g++ says it's non-portable not to specify the first
5291 argument in a varargs declaration. I introduced the first
5292 argument by using preprocessor conditionals.
5294 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
5296 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
5297 (scm_freopen): use RO string macros for filename and modes.

5311 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
5314 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,

5316 support for byte vectors.
5318 * print.c (scm_iprin1): Limit number of vector elements printed
5319 according to pstate->length.
5321 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>

5326 * error.h: prototype for scm_error_scm.
5328 * error.c (scm_error_scm): new procedure, reimplements scm-error
5329 in C and uses scm_error.
5331 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5333 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5334 pointer to the Scheme variable read-hash-procedures and intern it
5335 in scm_init_read. Modify scm_read_hash_extend and
5336 scm_get_hash_procedure to use the pointer.
5338 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5340 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5341 (SCM_KEYWORD_STYLE): defined.
5343 * read.c (scm_read_opts): add a keywords option. This isn't a
5344 boolean option, in case someone wants to add support for DSSSL
5346 Setup scm_keyword_prefix symbol.
5347 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5349 I've left keyword support disabled by default, since it doesn't
5350 seem to break the module system and it gives R4RS standard behaviour.
5351 It can be reactivated with (read-set! keywords 'prefix).
5353 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5355 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
5356 before constructing arbiter.
5358 * eval.c (scm_m_define): Bugfix: Check that the object is a
5359 closure before setting the procedure property!
5361 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
5363 * ports.c: Removed `ungetc-char-ready?'.

5367 * read.c (scm_init_read): intitialise scm_read_hash_procedures
5368 (idea from Mikael: make it a pair so scm_permanent object only
5370 (scm_read_hash_extend): don't call scm_permanent_object.
5371 (ideas from Mikael): if chr is already in the list, replace its
5372 procedure instead of appending it again. If proc is #f, remove
5374 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5376 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
5378 * gdbint.c (gdb_read): update scm_lreadr usage.

5392 for extended # processing.
5393 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
5394 scm_read_token): remove case_i, sharp arguments. Change callers.

5403 to determine whether to convert symbol case.
5404 (default_case_i): definition removed.
5405 * read.c (scm_read_token): if case_i, downcase ic before doing
5408 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5410 * configure.in: Added configuration option `guile-debug'.
5411 Configure with --enable-guile-debug if you want a bunch of extra
5412 functions used for debugging when developing Guile.
5414 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
5416 * procs.c (make-cclo): New undocumented debugging procedure: Make
5417 compiled closure with internal procedure PROC and length LENGTH.
5418 Only compiled if GUILE_DEBUG is defined.
5420 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
5422 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
5424 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
5426 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
5427 with 3 or more args internally to the evaluator.
5429 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5431 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
5432 with 3 or more args internally to the evaluator. This is mainly
5433 because we don't want to pass entry and exit points of the
5434 debug support twice, but it also seems to increase the speed of
5435 the evaluator for such calls (e. g. (+ 1 2 3)).
5437 * backtrace.c (scm_display_application): New procedure:
5438 display-application; Set fancy printing parameters individually
5439 for different types of display (backtrace, error, application).
5440 (These should of course be customizable!)
5442 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
5443 clear the CHECK-flags.
5445 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5447 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5449 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5451 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
5452 from pairs with a GLOC in the car.
5454 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
5455 otherwise `symbol-hash' will behave badly.
5456 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
5457 we get segmentation fault!
5459 * symbols.c: Added #include "weaks.h". New functions:
5460 `builtin-bindings' and `builtin-weak-bindings'. (These will be
5461 moved to an extraneous library when we split libguile.)
5463 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5465 * filesys.c (scm_stat): stat now takes fport arguments too as
5466 documented in the manual.
5468 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5470 * debug.c (scm_single_step): Bugfix: Call continuation with
5471 scm_call_continuation instead of throwing to it.
5473 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
5475 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
5476 argument wasn't declared to be optional.
5478 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5480 * stime.c (scm_init_stime): Add feature "current-time".
5482 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5484 * throw.h: prototype for scm_exit_status.
5485 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
5486 args to derive an exit status. Allows (quit) to work from a
5488 (scm_exit_status): new function.
5491 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5493 * eval.c (scm_deval): Removed some old code.
5494 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
5496 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
5499 * symbols.c (msymbolize): Bugfix: Must initialize property list to
5502 * procs.c: Introduce the existent C function scm_thunk_p at the
5503 Scheme level as well.
5505 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5507 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
5508 used from C to easily lookup the value of a symbol in the current
5511 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5513 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
5514 scm_init_unif in this file. This will also fix a previous problem
5517 * configure.in: Added AM_MAINTAINER_MODE
5519 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5521 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
5524 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5526 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
5527 source files that are not always included in libguile but should
5528 have their dependencies calculated by automake. This variable is
5529 recognized by automake, no further magic is needed.
5530 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
5531 to deal exclusively with *.lo files, as it seems. The *.o files
5532 are built automatically when the corresponding *.lo file gets
5535 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
5537 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
5540 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
5542 * unif.c (scm_array_set_x): minor change to argument error checking.
5544 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
5546 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
5547 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
5548 They should only be included in the library at configure.in's
5550 (libguile_la_LDADD): Include the appropriate .lo files here.
5551 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
5552 so we know when to build them (and their .lo bretheren).
5553 * configure.in (LIBLOBJS): New substituted variable. We let
5554 configure decide which .o files to include in LIBOBJS, and then
5555 put the corresponding list of .lo files in LIBLOBJS. The latter
5556 is what we pass to libtool.
5557 * Makefile.in, configure: regenerated.
5559 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
5561 * symbols.c (scm_sysintern0): New function. Contains the core of
5562 old scm_sysintern but doesn't take a second value argument.
5563 (scm_sysintern): Now uses scm_sysintern0.
5564 (scm_sysintern_no_module_lookup): Renamed to
5565 scm_sysintern0_no_module_lookup and doesn't take a second value
5566 argument any longer.
5568 * symbols.h (scm_sysintern0: Added declaration.
5570 * options.c (scm_init_opts): Use scm_sysintern0 instead of
5571 scm_sysintern when interning option keys. Otherwise we risk
5572 destroying the values of already interned variables.
5574 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
5575 scheme-level boolean (use SCM_NFALSEP).
5577 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
5579 (scm_backtrace): New function. (C version of old function from
5580 boot-9.scm) Motivation: Make it possible to display backtraces
5581 without depending on boot-9.scm. (I'm uncertain if this
5582 motivation is good enough...)
5584 * root.h (scm_root_state): Add member the_last_stack_var.
5585 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
5587 * root.c (mark_root): Mark scm_the_last_stack_var.
5589 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
5592 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
5594 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
5595 1. mark_lazy_catch didn't mark the smob.
5596 2. Both functions above have standard variants:
5597 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
5598 free_lazy_catch --> scm_free0.
5600 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
5602 * throw.c (scm_internal_lazy_catch): New function.
5603 (scm_lazy_catch): Rewritten to use it.
5604 (scm_ithrow): Handle the new lazy catch representation.
5605 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
5606 that doesn't have a jmpbuf is a lazy catch clause.
5607 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
5608 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
5609 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
5611 (scm_init_throw): Register the new lazy-catch smob type.
5612 * throw.h (scm_internal_lazy_catch): decl for new function.
5614 * throw.c (scm_internal_catch): Doc fixes.
5616 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
5617 configure.in. Including this might cause problems if applications
5618 that link against libguile include their own copies of alloca, but
5619 if they're using autoconf, they should be adding libguile to LIBS
5620 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
5621 the copy in libguile, and things will be okay. (I think.)
5623 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5625 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
5627 strop.h: move prototypes too.
5629 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5631 * posix.c (scm_init_posix): don't intern EINTR since it's now done
5634 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
5635 etc. I deleted them from filesys.c long ago, but didn't
5636 notice they were here too (although ineffective since
5637 sys/stat.h wasn't included).
5639 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
5641 * eval.c: Don't define alloca in GCC case. gcc will automatically
5642 use __builtin_alloca if appropriate.
5644 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5646 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
5647 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
5648 that values of automatic variables are preserved. See comments
5649 for safe_setjmp for details.
5651 Change from Thomas Morgan:
5652 * variable.c: Include eq.h.
5653 (var_equal): New function.
5654 (variable_smob): Use var_equal as the discriminator for variables.
5656 * throw.c (s_throw): Remove extraneous declaration.
5658 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
5659 * eval.c: Add necessary CPP cruft to support that.
5660 * configure, Makefile.in, scmconfig.h.in: regenerated.
5662 Change from Thomas Morgan:
5663 * procprop.c (scm_procedure_properties): Convert the Scheme
5664 boolean returned by scm_procedure_p into a C boolean before using
5665 it as a condition for SCM_ASSERT.
5666 (scm_procedure_property): Likewise.
5668 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
5669 indications of Unixness.
5672 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5674 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
5676 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5678 * read.c (scm_lreadr): use scm_misc_error to improve one of the
5679 "unknown # object" error messages.
5681 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
5682 (scm_i_index) and declare it static. Add a 'direction' argument
5683 to indicate what way the search should go.
5684 (scm_i_index): throw out-of-range error instead of wrong-type-arg
5686 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
5687 strop.h: remove scm_i_index, scm_i_rindex prototypes.
5689 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5691 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
5693 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
5694 to avoid clash with various scsh forks.
5696 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
5698 The following two changes (ramap.c, throw.c) are motivated by the
5699 apparent unportability of forward declarations of static arrays of
5700 the form `static foo bar[];'.
5702 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
5703 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
5705 * throw.c (scm_throw): Moved above scm_ithrow.
5707 * options.h: Removed the extern declarations of scm_yes_sym and
5708 scm_no_sym since these are static.
5710 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5712 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
5714 * Makefile.am: remove AWK=@AWK@.
5715 Add a rule for generating errnos.list.
5716 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
5718 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
5719 don't extract errnos, just set a variable (avoids the
5720 need to recompile error.c just because configure is run.)
5722 * unif.h: update prototypes.
5723 * unif.c (scm_uniform_array_read,write): change the offset and
5724 length arguments to start and end, for consistency.
5726 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
5728 * ioext.h: update prototypes.
5729 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
5730 scm_read_line_x, it's a more general procedure using an
5731 interface from scsh. read-line and read-line! are now defined
5733 Note that the new read-line trims the terminator
5734 by default, previously it was appended to the returned string. An
5735 optional argument specifies how to process the terminator (scsh
5736 compatible). For the old behaviour: (read-line port 'concat).
5737 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
5738 returns a pair, but is converted to multiple values if the scsh
5741 socket.h: update prototypes.
5742 * socket.c (scm_recvfrom): for consistency with other procedures,
5743 take start and end as separate optional arguments.
5744 (scm_recv, scm_recvfrom): don't allow the second argument
5745 to be a size, only a buffer. Change the scheme names to
5746 recv! and recvfrom!. Don't return the buffer.
5748 * ioext.h, posix.h: move prototypes too.
5749 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
5750 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
5751 "read.h" and "unif.h".
5752 * ioext.c: include "chars.h"
5754 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
5756 * dynl.c: The dynamic linking and module registration functions
5757 are now defined even when dynamic linking is not available for the
5758 host system. Some of their functionality can be done without
5759 dynamic linking; when it's really needed, they throw errors.
5761 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
5763 * configure.in: Only define DYNAMIC_LINKING when one of the system
5764 dependent functions is detected.
5765 * dynl.c (scm_dynamic_func): New function to get the address of a
5766 function in a dynamic object.
5767 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
5768 produced by scm_dynamic_func as the thing to call.
5770 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
5772 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
5773 (scm_register_module_xxx, scm_registered_modules,
5774 scm_clear_registered_modules): New functions.
5776 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
5778 * symbols.c (scm_sysintern): Renamed to
5779 scm_sysintern_no_module_lookup.
5780 (scm_sysintern): New function to take the place of the old
5781 scm_sysintern. It uses the current toplevel lookup closure to give
5782 the symbol its value. This is a temporary hack to put packages
5783 like gtcltk into their own module.
5784 (scm_can_use_top_level_lookup_closure_var): New variable to tell
5785 us whether `scm_top_level_lookup_closure_var' has been initialized
5787 * eval.c (scm_init_eval): Set it.
5789 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5791 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
5792 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
5794 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
5796 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
5797 scm_sys_dup): deleted: FD capability will be added to other
5799 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
5800 scm_fd_free, fd_smob, scm_intern_fd.
5801 (scm_open): renamed from scm_sys_open. Return a port instead of
5802 an FD object. Make the mode argument optional.
5803 (scm_sys_create): deleted, it's just a special case of open.
5804 (scm_init_filesys): move interning of constants O_CREAT etc.,
5805 here (were previously using SCM_CONST_LONG macro).
5806 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
5808 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
5809 include "fports.h" and <stdio.h>
5810 (scm_stat, scm_select): don't support FD objects.
5812 * error.h: adjust scm_syserror_msg prototype.
5813 * error.c (scm_syserror_msg): take an extra argument for errno.
5814 Using the global value didn't always work, since it could be
5815 reset by procedure calls in the message or args arguments.
5817 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
5818 I don't understand why the check was there (and what about the
5821 * strop.c (scm_string_copy): allow shared substrings to be copied.
5823 * unif.h: corresponding change to prototypes.
5824 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
5825 recognize two new optional arguments: offset and length. Allow
5826 the port argument to be an integer (file descriptor, for scsh).
5827 Include <unistd.h> for "read" prototype.
5829 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5831 * socket.c: don't include filesys.h.
5833 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
5835 * Makefile.am: add AWK=@AWK@ (?)
5837 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
5839 Add a rule to generate errnos.c from errnos.
5840 * error.c (scm_init_error): include errnos.c.
5841 * errnos_cnvt.awk: new file, converts the list of errno codes to
5843 * errnos_get.c: new file.
5844 * errnos.default: new file, contains errnos to try if they can't
5845 be extracted from errno.h.
5846 * configure.in: if using GCC, try and extract errno codes from
5850 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
5852 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
5853 * Makefile.am: Made libguile into a libtool library.
5854 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
5855 Set libtool_libs to indicate that libguile is a libtool library.
5856 See guile/ChangeLog for details.
5857 * .cvsignore: ignore "*.lo", the libtool library objects.
5859 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5861 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
5862 use htons in getservbyport argument.
5864 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5866 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
5867 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
5870 * objprop.c (scm_object_property): No need to take the CDR of the
5871 value returned by scm_object_properties, since Aug 20 change.
5873 * configure.in: When checking for struct linger, #include
5874 <sys/types.h> as well as <sys/socket.h>. I've never known
5875 <sys/types.h> to cause any portability problems, and Solaris's
5876 <sys/socket.h> needs it.
5877 * configure: Rebuilt.
5879 I think the Sun compiler has chosen a perverse way to interpret
5880 ANSI declarations combined with K&R definitions. We'll
5881 appease it a little bit. But when it invades France, we fight.
5882 * print.c (scm_iprlist): Change 'tlr' argument to an int.
5883 * print.h (scm_iprlist): Here too.
5884 * numbers.c (scm_divbigdig): Change definition to match
5885 declaration in numbers.h.
5886 * unif.c (scm_makflo): Change definition to match declaration in
5889 * init.c (scm_boot_guile): Don't return the value of
5890 scm_boot_guile_1. This function doesn't return a value;
5891 scm_boot_guile_1 doesn't return a value (or return at all).
5893 * eval.c (unmemocopy): Add a semicolon to appease the Sun
5896 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
5897 compile. I have a feeling this function is a bad idea anyway ---
5898 one should always test for features, not systems.
5900 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
5901 semicolons. Only pure luck kept this from being noticed earlier.
5903 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
5905 * socket.c (scm_recvfrom): Added missing semicolon.
5907 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5909 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
5910 the buffer and start and end positions for scsh networking
5913 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
5915 * configure.in: Revert previous change to this file; the problem
5916 is due to transient automake weirdness.
5917 * configure: Rebuilt.
5919 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
5920 PLUGIN/guile.libs. configure generates the latter from the former.
5921 * Makefile.in: Rebuilt.
5923 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
5924 need this if we install scripts, like guile-snarf.
5925 * configure: Rebuilt.
5927 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5929 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
5931 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
5933 * socket.c (scm_addr_vector): fix faulty scm_listify.
5935 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
5937 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
5938 style block comment is no longer considered an error.
5940 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
5942 * PLUGIN/guile.libs.in: New file.
5943 * PLUGIN/guile.libs: Removed from repository.
5944 * configure.in: Create PLUGIN/guile.libs from
5945 PLUGIN/guile.libs.in. This is for including additonal libraries
5946 needed for dynamic linking.
5947 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
5948 instead of PLUGIN/guile.libs.
5950 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
5952 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
5954 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
5955 occurrences of the given element from the list, not just the
5956 first. This is how the Emacs Lisp functions behave, how the
5957 analogous Common Lisp functions behave, and (I believe) how the
5958 older Maclisp functions worked. I realize that this change may
5959 break code, but it seemed better to break it before the Guile
5962 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
5963 Their prototypes were already present in gc.h, but they weren't
5965 (scm_init_storage): Initialize scm_protects.
5966 * root.c (scm_protects): New element of scm_sys_protects.
5968 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
5970 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
5972 * libguile.h: Added #include "libguile/net_db.h".
5974 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
5975 30 change. That file is only meant for communication between the
5976 configuration process and load.c. If code linked against libguile
5977 wants to get at the paths mentioned in libpath.h, it can call
5978 functions declared in load.h.
5980 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5982 * libguile.h: Removed #include "libguile/fdsocket.h"
5984 * net_db.c: Added #include <sys/socket.h>.
5986 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
5988 * filesys.c (scm_input_waiting_p): use select in preference to
5989 FIONREAD, since the latter doesn't detect EOF.
5990 Throw error if neither select nor FIONREAD available.
5992 * socket.c (scm_connect): take a port, not a fd object.
5993 (scm_fill_sockaddr): throw an error if fam is not recognised.
5994 (scm_bind): use scm_fill_sockaddr.
5995 (scm_listen): take a port, not a fd object.
5996 (scm_accept): take and return a port. return #f in the car if
5997 address can't be got
5998 (scm_sock_fd_to_port): new procedure.
5999 (scm_socket): use scm_sock_fd_to_port.
6000 (scm_addr_vector): throw error if unrecognised address type.
6001 take an extra argument with the calling procedure name.
6002 (scm_getsockname): take a port. return #f if address can't be got.
6003 (scm_getpeername): take a port. return #f if address can't be got.
6004 (scm_recvfrom): take a port. return #f for address component if can't
6006 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
6007 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
6009 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
6011 * throw.c (scm_internal_catch): Make body funcs and handler funcs
6012 use separate data pointers, to allow them to be designed
6013 independently and reused.
6014 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
6015 Renamed from catch_body, catch_handler, and uncaught_throw; made
6017 (struct scm_catch_body_data): Renamed from catch_body_data; moved
6019 (scm_catch): Use the above.
6020 (scm_throw): Don't bother printing a message for an uncaught
6021 throw; we establish a default handler in init.
6022 * throw.h (scm_internal_catch): Prototype updated.
6023 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
6025 (struct scm_body_thunk_data): New structure, used as data
6026 argument to scm_body_thunk.
6027 * init.c (struct main_func_closure): New structure, packaging up
6028 the data to pass to the user's main function.
6029 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
6030 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
6031 scm_internal_catch to establish a catch-all handler, using
6032 scm_handle_by_message. This replaces the special-case code in
6034 (invoke_main_func): Body function for scm_internal_catch; invoke
6035 the user's main function, using the main_func_closure pointer to
6036 decide what to pass it.
6037 * root.c (struct cwdr_body_data): Remove handler_proc member.
6038 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
6039 (cwdr_handler): Removed.
6041 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6043 * socket.h (SCM_P): update bind prototype.
6044 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
6045 include "feature.h".
6046 (scm_socket): return a port, not a file descriptor object.
6047 include "fports.h" and <unistd.h>
6048 (scm_bind): take a port, not a file descriptor object.
6049 take an extra argument for address args.
6051 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
6052 INADDR_NONE, INADDR_LOOPBACK.
6054 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6056 * init.c: include net_db.h and not fdsocket.h.
6057 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
6059 * Makefile.am: corresponding changes.
6060 * socket.h: renamed from fdsocket.h, fix names.
6061 * net_db.h: renamed from socket.h, fix names.
6062 * socket.c: renamed from fdsocket.c.
6063 remove _sys from procedure names.
6064 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
6065 add "socket" to features list.
6066 * net_db.c: renamed from socket.c.
6067 remove _sys from procedure names.
6068 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
6069 add "net-db" to features list.
6070 include "net_db.h". don't include <sys/socket.h> or
6073 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6075 * tags.h (scm_tags): Removed comma at end of last enumerator.
6077 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
6079 Don't use GCC extensions to allocate space for debugging frames.
6080 (Here he goes again! Why do we put up with this?!)
6081 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
6082 an scm_debug_info structure, not an in-line array of them. Add
6083 'info' member, to say how many vect elements we've used, for eval
6085 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
6086 a new variable debug_info_end to mark the end of vect, instead of
6087 the address of the 'info' pointer itself.
6088 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
6089 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
6090 (SCM_APPLY): Explicitly allocate space for debug.vect.
6091 * debug.c (scm_m_start_stack): Same, for vframe.vect.
6092 * stacks.c: Adjusted for new debug frame structure.
6093 (RELOC_INFO, RELOC_FRAME): New macros.
6094 (stack_depth, read_frames): Use them, and new scm_debug_frame
6095 element 'info', instead of magically knowing that eval frames have
6096 an info pointer sitting after vect.
6097 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
6099 (scm_init_stacks): Formatting tweaks.
6101 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
6103 Give GCC more control flow information, so it can be sure that
6104 variables aren't used uninitialized.
6105 * error.h (scm_error, scm_syserror, scm_syserror_msg,
6106 scm_sysmissing, scm_num_overflow, scm_out_of_range,
6107 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
6108 scm_misc_error): Tell GCC that these functions never return.
6109 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
6110 out the field type, call abort if SCM_ASSERT returns, to placate
6112 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
6113 scm_wta ever returns. We can't handle this case anyway, and this
6114 gives the optimizer more information.
6115 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
6116 scm_wta ever returns.
6118 In some cases, the code is fine, but GCC isn't smart enough to
6119 figure that out; this usually happens when one variable is only
6120 initialized and used when a particular condition holds true, and
6121 we know that condition will never change within a given invocation
6122 of the function. In this case, we simply initialize the variables
6123 to placate the compiler, hopefully to a value which will cause a
6124 crash if it is ever actually used.
6125 * print.c (scm_iprin1): Initialize mw_pos.
6126 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
6127 * throw.c (scm_ithrow): Initialize dynpair.
6128 * unif.c (scm_uniform_vector_ref): Initialize cra.
6129 * struct.c (init_struct): Initialize prot.
6130 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
6132 * strports.c (scm_eval_0str): Don't return uninitialized garbage
6133 if EXPR contains no expressions.
6135 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6137 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
6138 cause an infinite loop (???). So much for the algebraic
6139 equivalency of variable-sized arrays and alloca...
6141 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
6143 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
6144 a SCM boolean, not a C boolean.
6146 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
6148 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
6149 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
6150 rules for raising scm_mtrigger. Previously, unfortunate but not
6151 unlikely circumstances could result in almost constant invokation
6152 of the gc. Now, this situations should be less likely, but they
6153 are not prevented completely.
6155 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
6157 * numbers.c (scm_fuck): Procedure removed; looks like old test
6159 * numbers.h: Prototype removed.
6161 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
6163 * debug.h (scm_debug_frame): Change `vect' member from an in-line
6164 array to a pointer, to match my Nov 21 change in eval.c.
6166 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6168 * libguile.h: Added #include "libguile/backtrace.h", #include
6169 "libguile/stacks.h".
6171 * strings.c (scm_string scm_make_string scm_string_ref
6172 scm_string_set_x scm_string_equal_p scm_string_append):
6173 Bugfix according to scm patch from Aubrey Jaffer:
6174 Corrected long-standing
6175 (not (eqv? (integer->char 128)
6176 (string-ref (make-string 1 (integer->char 128)) 0)))
6177 bug found by John Kozak <jk@noontide.demon.co.uk>.
6179 * strports.c, strports.h: Make scm_eval_0str return the value of
6180 the last expression evaluated (previously, it returned void).
6182 * strports.c, strports.h: New function: scm_read_0str. Does what
6185 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6187 * simpos.c (scm_getenv): return #f if string can't be found in the
6188 environment instead of throwing an exception, for compatibility
6189 with numerous other systems.
6191 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6193 * Makefile.am (.c.x): Use guile-snarf.
6194 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6196 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6198 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6200 * backtrace.c (scm_display_error_message): Made non-static, and
6201 renamed from display_error_message.
6202 * backtrace.h (scm_display_error_message): Added extern decl.
6203 * throw.c (uncaught_throw): Use it to display the error message.
6205 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6207 * inet_aton.c: Use #if 0, not #ifdef 0.
6209 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6211 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6212 to convert the returned value.
6213 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6214 the offset argument.
6216 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6218 Add new interface to catch/throw, usable from C as well as
6220 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6221 (scm_internal_catch): New function, replaces...
6222 (scm_catch_apply): Deleted.
6223 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6224 mechanism which is a bit more code, but can be used nicely from C
6225 and implement the Scheme semantics as well.
6226 (scm_internal_catch): This is the replacement; it's named after
6227 the analogous function in Emacs.
6228 (scm_catch): Reimplemented in terms of the above.
6229 (struct catch_body_data, catch_body, catch_handler): New
6230 functions, used by scm_catch.
6231 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6232 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6233 support for new cwdr.
6235 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6238 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6240 * acconfig.h: Added DYNAMIC_LINKING symbol.
6241 * configure.in: Add option and checks for dynamic linking.
6242 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6243 dynl.h: New files for dynamic linking support.
6244 * Makefile.am (libguile_a_SOURCES):
6246 (modinclude_HEADERS): Added "dynl.h".
6247 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
6249 * init.c (scm_boot_guile_1): Call
6250 scm_init_dynamic_linking to initialize dynamic linking support.
6252 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
6254 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
6255 (as we Schemers say). It needs to be global, so that I can tweak
6256 it for the proper operation of unexec.
6257 (scm_boot_guile_1_live): New variable, see above.
6259 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
6261 * guile-snarf.sh: Removed.
6262 * PLUGIN/guile.libs: Added dependency for -lm.
6263 * acinclude.m4: Renamed from aclocal.m4.
6264 * PLUGIN/greet: Removed.
6265 * Makefile.am, aclocal.m4: New files.
6266 * configure.in: Updated for Automake.
6268 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
6270 * eval.c (scm_definedp): Use top_level_lookup_closure_var
6271 and not top_level_lookup_thunk_var.
6273 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
6275 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
6277 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
6279 * eval.c (scm_definedp): Incompatibly changed to be a builtin
6280 Scheme function, instead of syntax. Single argument is now a
6283 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6285 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
6286 scm_ra_divide): Properly terminate statements passed as arguments
6287 to IVDEP macros. (Thanks to Bernard Urban.)
6289 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
6290 with non-constant sizes. (Thanks to Bernard Urban.)
6292 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6294 It's an "eval closure", not an "eval thunk." A thunk is a
6295 function of no arguments.
6296 * root.h (struct scm_root_state): Renamed
6297 top_level_lookup_closure_var from top_level_lookup_thunk_var.
6298 (scm_top_level_lookup_closure_var): Renamed from
6299 scm_top_level_lookup_thunk_var.
6300 * root.c (mark_root): Uses changed.
6301 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
6302 * init.c (scm_start_stack): Uses changed.
6303 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
6304 Change scheme-visible name to *top-level-lookup-closure* from
6305 *top-level-lookup-thunk*.
6307 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
6309 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
6310 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
6312 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
6314 * gc.c (struct scm_heap_seg_data): Doc fixes.
6316 * gc.c (scm_gc_sweep): Empty all segments' freelists before
6317 sweeping. Then, prepend each segment's free cells to its
6318 freelist, rather than wiping out the old value. (Thanks to Marius
6321 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6322 scm_check_freelist, scm_debug_newcell): New functions and
6323 variables, for debugging freelist problems.
6324 * pairs.h (SCM_NEWCELL): New debugging version added.
6325 * gc.h (scm_debug_newcell): Added extern declaration, used by
6326 debugging version of SCM_NEWCELL.
6328 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6330 On some systems <libc.h> conflicts with <unistd.h>, and should not
6331 be #included at all.
6332 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6333 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6334 * configure.in: Call it.
6335 * posix.c, filesys.c: Use its results to decide whether or not to
6337 * configure, scmconfig.h.in: Rebuilt with autoconf and
6340 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6342 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6343 pointer to the stdio stream before calling scm_setbuf0, so the
6344 latter will be able to retrieve it. I'm surprised this didn't
6345 segfault earlier. (Thanks to Christopher Lee.)
6347 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6349 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6352 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6354 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6355 number of stack narrowing specifier pairs. The first specifier in
6356 a pair controls inner border, the second the outer border. A
6357 number means cut that number of frames, a procedure object means
6358 cut until that object is found in operator position in a frame.
6360 * root.c (cwdr): Bugfix.
6362 * read.c: Recording of positions disabled by default.
6364 * procs.c (scm_closure_p): New function.
6366 * posix.c (scm_tmpnam): New function.
6368 * load.c: Added #include "throw.h".
6369 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6372 * load.c, load.h (scm_read_and_eval_x): New function.
6374 * eval.c: Renamed debug option "deval" to "debug".
6376 (scm_eval_x): `eval!' is no longer accessible from the scheme
6377 level. Motivation: We can't allow operations which introduce
6378 glocs into the scheme level. Guile's type system can't handle
6379 these as data. Use `eval' or `read-and-eval!' as replacement.
6381 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6382 SCM_CONSP since this is a macro!; Set vframe.prev to
6383 scm_last_debug_frame instead of 0. In this way we can look
6384 "above" the virtual start stack frame if we wish.
6385 (scm_debug_hang): New function: Useful for debugging Guile in
6386 certain tricky situations. Will probably be removed later...
6388 * debug.h: Changed semantics of debug option "backtrace". This
6389 option now only indicates whether we want automatic backtrace at
6392 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6394 * ports.c: #include "filesys.h"
6395 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
6397 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
6398 Motivation: This is system specific code which is related to file
6399 I/O. It also may use select. Added code by Gary Houston to
6400 detect presence of character in stdio buffers.
6402 * libguile.h: #include "libguile/libpath.h"
6404 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
6405 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
6406 SCM_SITE_DIR; Install libpath.h among the other include files.
6408 * load.c, load.h (scm_sys_package_data_dir): New function.
6410 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6412 * stacks.h: Bugfix: Don't use tail-array length field as stack
6413 length field! This screwed GC.
6415 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6417 * _scm.h: Added #ifndef around definition of macros min and max.
6419 * __scm.h: Added hooks for threads to plugin to in ints protection
6420 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
6421 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
6422 the main code in these macros duplicated and spread over multiple
6423 files. Renamed SCM_THREADS_SWITCHING_CODE ->
6424 SCM_THREAD_SWITCHING_CODE.
6426 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
6428 * snarf.h: New file.
6429 * guile-snarf.sh: New file.
6430 * Makefile.in (inner_h_files): Added snarf.h
6431 (ancillary, install, uninstall, distclean): Added actions for
6433 (.c.x): Use guile-snarf.
6434 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
6435 (gen_c_files): Note that these depend on guile-snarf.
6436 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
6437 now in "snarf.h". Added #include "snarf.h" to get them.
6438 * libguile.h: Added #include "snarf.h".
6439 (Patches applied and tweaked by Jim Blandy.)
6441 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6443 * socket.c: Use K&R style declaration for 'close'; the GNU coding
6444 standards suggest against providing prototypes for system
6445 functions. Thanks to Greg Troxel.
6447 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6449 * strports.c (scm_eval_0str): New function.
6450 #include "read.h", to get prototype for scm_read.
6451 * Makefile.in (strports.o): Update dependencies.
6452 * strports.h: New prototype.
6454 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
6455 scheme name from "int?" to "integer?". It seems to do the job.
6456 * numbers.h: Rename prototype too.
6457 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
6460 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
6461 scm_num_eq_p): Rename these according to R4RS conventions: call
6462 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
6463 to making libguile R4RS compliant without ice-9...
6465 * load.c (scm_sys_search_load_path): Search for files under all
6466 extensions listed in the %load-extensions variable. If FILENAME
6467 is absolute, return it unchanged, without searching the load path.
6468 (scm_loc_load_extensions): New variable, pointing to
6469 %load-extensions' value cell.
6470 (scm_init_load): Initialize it, and the value it points to.
6471 (scm_primitive_load_path): Improve error reporting.
6473 * load.c (scm_loc_load_hook): New variable, pointing to value cell
6474 of new Scheme variable %load-hook.
6475 (scm_primitive_load): Apply %load-hook to filename.
6477 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
6479 * configure.in: add tests for figuring out whether buffered data
6480 is available in a FILE structure, which is needed by char-ready.
6482 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
6485 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
6486 exceptions using misc_error instead of syserror. It seems a bit
6487 odd to throw an exception if a string can't be found in the
6488 environment, but it's consistent with open-file, stat etc.
6489 (simpos.h): remove sys_ from getenv.
6491 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
6492 occurs, throw an error instead of returning errno. Return value
6494 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
6496 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
6498 * filesys.c (scm_stat2scm): derive file type and permissions from
6499 the stat mode and append them to the returned vector.
6500 There isn't much overhead in doing this and it avoids the need to
6501 work with S_IRUSR et al. in Scheme.
6502 Define symbols scm_sym_regular etc.
6503 (scm_init_filesys): don't intern S_IRUSR etc.
6505 * load.c: change s_try_load and s_try_load_path to s_primitive_load
6506 and s_primitive_load_path.
6508 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
6510 * error.h: don't declare error symbols. prototype for scm_misc_error.
6512 * stackchk.c (scm_stack_overflow_key): defined here instead of in
6515 * error.c: use SCM_SYMBOL to set up error keys.
6516 scm_misc_error: new procedure.
6518 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
6520 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
6521 between `#!' and `!#' is ignored.
6522 (skip_scsh_block_comment): New function.
6524 * feature.c (scm_set_program_arguments): New argument, FIRST.
6525 * feature.h: Update prototype.
6526 * init.c (scm_boot_guile_1): Pass new argument to
6527 scm_set_program_arguments.
6529 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6531 * init.c (scm_start_stack): Don't initialize scm_progargs here.
6532 (scm_boot_guile): Call scm_set_program_arguments here, later than
6533 the old initialization.
6535 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
6536 initialization procedure.
6537 - Delete in, out, err arguments; there are other perfectly good
6538 ways to override these when desired.
6539 - Delete result argument; this function shouldn't ever return.
6540 - Rename init_func argument to main_func, for less confusion.
6541 - Delete boot_cmd argument; main_func is more general.
6542 -Add 'closure' argument, to help people pass data to main_func
6543 without resorting to global variables.
6544 - Abort if reentered; don't bother returning an error code.
6545 - Call scm_init_standard_ports to set up the default/current
6546 standard ports; no need to pass them to scm_start_stack.
6547 - Remove code to evaluate the boot_cmd, and start the repl; let
6548 the user do something like that in main_func if they want.
6549 - Remove code to package up a return value; main_func can do any
6551 - Call exit (0), instead of returning.
6552 (scm_start_stack): Don't initialize the I/O ports here; that's
6553 weird. Delete in, out, err arguments. Move guts to
6554 scm_init_standard_ports, scm_stdio_to_port.
6555 (scm_init_standard_ports): New function, to set up current and
6556 default standard ports.
6557 (scm_start_stack, scm_restart_stack): Make these static.
6558 * init.h (scm_boot_guile): Adjust declaration.
6559 (scm_start_stack, scm_restart_stack): Remove externally
6560 visible declarations for these.
6561 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
6563 * fports.c (scm_stdio_to_port): New function. Its guts used to be
6564 written out several times in scm_start_stack.
6565 * fports.h: New declaration for the above.
6567 * feature.c (scm_set_program_arguments): New function.
6568 * feature.h: New declaration for the above.
6570 * ports.c: Formatting tweak.
6572 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
6574 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
6575 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
6576 for obtaining the address of a car or cdr field. Motivation:
6577 &SCM_CXR make assumptions about the internal structure of the
6580 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
6581 Motivation: see SCM_CXRLOC.
6583 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
6584 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
6585 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
6586 Motivation: Safer use. Some other macros are defined in terms of
6587 these operations. If these are defined using the SCM_SETCXR
6588 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
6589 to inefficiency and an <e1> with side-effects could potentially
6590 break. Also, these particular operations are heavily utilized in
6591 the garbage collector. In unoptimized code there will be a
6594 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
6595 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
6596 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
6597 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
6598 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
6599 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
6600 vports.c: Cleaned up use of pairs: Don't make any special
6601 assumptions about the internal structure of selectors and
6602 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
6603 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
6604 (Among other things, this change makes it easier to build Guile
6605 with certain compilers which have problems with casted lvalues.)
6607 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6609 * stacks.c: Improve selection of relevant stack frames when making
6610 a stack object. Introduce one level of indirection in the stack
6611 object to make it possible to "narrow" to a certain region of the
6612 stack. This facilitates making use of more clever algorithms (not
6613 implemented) for selecting relevant frames and gives a cleaner
6614 design since selection of frames can be done independently of
6615 extraction of frames from the real stack.
6616 (scm_stack_id): Also take #t as argument which means look at
6619 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
6620 Turn n_tail into an integer directly representing current number
6621 of frames in stack. Add field tail.
6623 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
6625 * debug.c (scm_make_memoized): Made it available at scheme level.
6626 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
6627 SCM_NIMP before applying heavier predicates in argument checking.
6628 (scm_local_eval): Also take memoized object as argument.
6630 * backtrace.c (scm_display_error): Just a safety measure: Stacks
6631 aren't created with zero length, but should such a strange
6632 creature suddenly turn up...
6634 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
6636 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
6637 `del', for the sake of C++ compilers. (Patch applied by JimB.)
6639 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
6641 * variable.c (scm_make_variable): Make the name hint optional, as
6643 (anonymous_variable_sym): Renamed from variable_sym. All uses
6646 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
6647 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
6648 of scm_primitive_load_path was also changed to
6649 "primitive-load-path", from "%try-load-path". Callers changed.
6650 We'd like to respect the convention that a function named
6651 "try-mumble" should behave just like the function called "mumble",
6652 but return #f instead of signalling some error.
6653 * load.h: Rename prototypes.
6655 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6657 * print.c (make_print_state, grow_print_state), print.h: Modified
6658 the print state representation: Don't use a tail array for
6659 recording of circular references. Resizing of the print state
6660 structure invalidates the print state pointer. To avoid passing
6661 around an indirect print state reference to all printing
6662 functions, we instead let the print state reference a resizable
6665 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
6667 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
6668 Don't crash when passed an improper list terminated by a
6669 non-immediate value.
6671 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
6673 Allocate data for structures on an eight-byte boundary, as
6674 required by the tagging system.
6675 * struct.c (alloc_struct): New function.
6676 (scm_make_struct, scm_make_vtable_vtable): Call it.
6677 * struct.h (scm_struct_n_extra_words): Bump to 3.
6678 (scm_struct_i_ptr): New "field".
6679 * gc.c (scm_gc_sweep): When we need to free the data, use the
6680 information stored by alloc_struct to find the beginning of the
6681 block allocated to the structure, so we can free it.
6683 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6685 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
6688 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
6689 (scm_debug_info): New member: id.
6691 * stacks.c: Stacks are now represented as structs; Stacks have an
6692 id given to them by `start-stack'.
6693 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
6695 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
6696 Changed stack representation.
6698 * debug.c (scm_procedure_name): Try procedure property `name' for
6699 compiled closures aswell.
6701 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
6703 * eval.c: scm_i_name moved to gsubr.c
6704 (scm_m_define): Record names of all kinds of procedure
6705 objects. (Earlier, only closures were recorded.)
6707 * procprop.h: Added declaration of scm_i_name.
6709 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
6710 (scm_make_gsubr): Record names of compiled closures.
6712 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6714 * debug.c, debug.h: Removed obsolete code.
6716 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
6717 stacks.c: Renamed regs --> scm_contregs.
6719 * print.c (scm_free_print_state): Cleanup print state before
6720 returning it to pool. It is better to do it here than in
6721 scm_prin1 since scm_prin1 is called often.
6723 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
6724 s_set_source_property_x): Check that first argument is a pair or a
6727 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
6728 scm_i_line, scm_i_column and scm_i_breakpoint global.
6730 * init.c: Added #include "backtrace.h" and #include "stacks.h".
6731 (scm_boot_guile_1): Added calls to scm_init_backtrace and
6734 * debug.h: Added debug object smob declaration and macro
6737 * configure.in: Build with backtrace.o and stacks.o if debug
6740 * Makefile.in: Added entries for new files: backtrace.c,
6741 backtrace.h, stacks.c and stacks.h.
6743 * symbols.c (scm_sym2ovcell): Fixed documentation.
6745 * _scm.h (min, max): Added.
6747 * async.c: Moved `min' macro to _scm.h.
6749 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
6750 SCM_BACKTRACE_INDENT.
6752 * eval.c: Added new debug options `maxdepth' and `indent'.
6754 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
6756 * print.h: Added selector SCM_PRINT_STATE.
6758 * print.c: New functions: scm_make_print_state,
6759 scm_free_print_state.
6761 * print.h: Added declarations for scm_make_print_state,
6762 scm_free_print_state.
6764 * debug.c (scm_m_start_stack): New acro.
6766 * debug.h: Small cleanup.
6768 * init.c (scm_boot_guile_1): Moved scm_init_debug below
6771 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

6796 More prototype-related changes from Marius Vollmer:
6797 * gdb_interface.h: Wrapped header file in #ifdef/#endif
6798 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
6799 * ports.h (ptobfuns): Added prototypes. This means some casting in
6801 * fports.c: Added casts for initializations, since the functions
6802 are defined to take FILE * as their stream argument, not SCM.
6803 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
6804 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
6805 to `char *str_data' to conform to prototype.
6807 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
6809 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
6811 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
6813 * stime.c, stime.h: use SCM_P method.
6815 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
6817 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
6818 be given at least two arguments. Insist that lst's last element
6819 be a list, but don't make any requirements of its predecessors.
6821 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
6823 * eval.c (scm_nconc2last): Revert last change; there seems to be
6824 other stuff going on here.
6826 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
6828 * eval.c (scm_nconc2last): Make sure that each element of lst
6829 (which is a list of argument lists, except for the tail) is a
6830 proper list, i.e., finite and terminated by '().
6832 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6834 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
6837 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
6838 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
6841 * vectors.c (scm_make_vector): Fill vectors with the undefined
6842 value, to help make Guile Scheme code more portable to other
6845 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
6846 * symbols.h, tags.h: Doc fixes.
6848 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
6850 * async.c (scm_take_signal): Doc fixes.
6852 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
6854 * numbers.c (scm_divbigint): When the remainder is zero, we don't
6855 want to subtract it from the modulus; we just want to leave it
6858 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
6860 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
6863 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
6865 * throw.c (scm_catch_apply): Finished implementation of
6868 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
6870 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
6872 (scm_init_filesys): set "i/o-extensions" feature.
6875 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
6877 * Makefile.in (root.o): Correct dependencies.
6879 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
6881 * Makefile.in: Added dependency entry for root.o.
6883 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
6884 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
6886 * init.c (scm_start_stack): Set initial root continuation number
6889 * procs.c: New function: scm_thunk_p.
6891 * procs.h: Added declarations of scm_thunk_p.
6893 * root.c: Renamed `call-with-new-root' -->
6894 `call-with-dynamic-root'.
6895 (cwdr): Removed allocation of new root state. This should be done
6896 separately by use of scm_make_root.
6897 (scm_apply_with_dynamic_root): New function: Does what it
6898 sounds like. Needed when spawning threads.
6900 * root.h: Added member last_debug_frame to root state.
6901 Added #include "libguile/debug.h"
6903 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
6904 arguments. The motivation is that code in root.c needs catch
6905 functionality, and we want to avoid code duplication.
6906 New functions: scm_catch, scm_lazy_catch. These are wrappers for
6907 scm_catch_apply. scm_lazy_catch is intended to introduce catch
6908 handlers that run without popping the stack into the dynwind
6911 * throw.h: Added prototypes for scm_catch_apply and
6914 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6916 * root.h (scm_root, scm_set_root): Decouple thread support details
6917 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
6918 SCM_SET_THREAD_LOCAL_DATA.
6920 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
6921 and tortoise scanning loop.
6923 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
6925 * Makefile.in: Rebuild dependencies.
6927 * libguile.h: #include "libguile/print.h" before "smob.h", since
6928 the latter uses the print_state structure.
6930 * throw.c (scm_ithrow): Use the correct variable when checking to
6931 see if a given element of scm_dynwinds is a valid catch.
6933 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
6934 structure, abort; don't just silently ignore the garbage.
6936 * _scm.h: #include "print.h" here, since it seems to be used just
6938 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
6939 strports.c, unif.h: Don't #include "print.h".
6941 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6943 * feature.h (scm_loc_features): Removed external declaration.
6944 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
6946 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6948 * feature.c (scm_init_feature): Added threads feature (needs to be
6949 initialized here, since features doesn't exist when
6950 scm_init_threads is called).
6952 * libguile.h: Added #include "libguile/../threads/threads.h".
6953 (This is a kludge to get thread support working. This should be
6956 * configure.in, acconfig.h: Added flags for thread support.
6958 * scmsigs.c: Define `signal' to be `pthread_signal' if using
6961 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
6962 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
6965 * _scm.h: Added conditional #include "threads.h"
6967 * __scm.h (SCM_ASYNC_TICK): Added call to macro
6968 SCM_THREADS_SWITCHING_CODE.
6970 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
6971 allocate the basic dynamic root object.
6972 (scm_boot_guile): Added call to scm_init_root.
6974 * root.c, root.h: Added root smob.
6975 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
6976 functions: Implements dynamic roots mostly according to spec in
6977 SCM manual. Main difference is that the second argument is a
6978 throw handler rather than an error "thunk".
6980 * root.h: Added declaration of scm_init_root.
6982 * root.c: Added #include "genio.h", #include "smob.h", #include
6983 "pairs.h", #include "throw.h", #include "dynwind.h", #include
6985 (scm_init_root): Added #include "root.x".
6987 * throw.c: Added #include "stackchk.h"
6988 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
6989 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
6990 can be used in scm_call_with_new_root; Added reenabling of stack
6991 checking when catching a throw.
6993 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
6995 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
6997 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
6998 element is not found, as per R4RS.
7000 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7002 * list.c: Doc fixes throughout.
7004 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7006 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
7007 declare the char * to be const. Avoids a warning in rgx.c.
7009 * ports.h: spelling fix.
7011 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
7014 * load.c (scm_sys_try_load_path): throw an error if file not found
7015 (like it says it in NEWS).
7017 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7019 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
7020 PROPS slot to '(), not #f; it's an empty alist.
7022 * throw.h, throw.c: Use SCM_P instead of #if hair.
7024 Remove special support for uncaught throws; see throw.c for
7026 * throw.c (uncaught_throw): New function.
7027 (scm_ithrow): Call uncaught_throw if we don't find a throw
7028 target; don't mess with scm_bad_throw_vcell.
7029 (scm_bad_throw_vcell): Variable deleted.
7030 (scm_init_throw): Don't initialize it.
7032 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
7035 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7037 * numbers.c (scm_istr2int): If the number is short (as most
7038 numbers are), just call scm_small_istr2int to deal with it.
7039 (scm_small_istr2int): New function, created by un-#ifdefing the
7040 non-bignum version of scm_istr2int and renaming it.
7042 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
7044 * load.c (scm_sys_try_load): don't check whether value returned
7045 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
7046 Change the Scheme name from %try-load to primitive-load.
7048 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
7049 Can avoid passing a message, allowing it to be derived in the
7050 error handler (e.g., if we want to throw to the key both from
7053 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
7055 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
7056 references now have a new appearance which is more compact and
7057 also gives a clue about what the target of the reference is.
7058 By setting parameters in the print state, more fancy printing can
7059 be achieved. This is used by the (not yet commited) backtrace
7062 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
7064 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
7067 * print.c: Added #include "struct.h". Removed function
7070 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
7071 scm_iprin1. Removed prototype for scm_prlist.
7073 * arbiters.c (prinarb),
7074 async.c (print_async),
7075 debug.c (prindebugobj, prinmemoized),
7076 eval.c (prinprom, prinmacro),
7077 filesys.c (scm_fd_print, scm_dir_print),
7079 mallocs.c (prinmalloc),
7080 numbers.c, numbers.h (scm_floprint, scm_bigprint),
7081 smob.h (scm_smobfuns),
7082 srcprop.c (prinsrcprops),
7084 unif.c, unif.h (scm_raprin1, rapr1),
7085 variable.c (prin_var): Changed argument `int writing' to
7086 `scm_print_state *pstate'.
7088 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
7089 that it will be called before scm_init_print.
7091 * print.c (scm_prin1): Print states are now allocated when calling
7092 scm_prin1 and then passed around to all printing functions as an
7093 argument. A cache `print_state_pool' enables reuse of print
7095 (scm_make_print_state): New function.
7096 (scm_iprin1): Adaption to print states.
7097 (scm_iprlist): An initial "hare and tortoise" scan brings down
7098 time complexity to O (depth * N). (Better time complexity will be
7099 achieved when the printing code is completely rewritten.)
7101 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7103 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
7104 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
7105 it gets done whether or not the cache variable has a value.
7107 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7109 Distinguish #f and ().
7110 * __scm.h: #undef SICP.
7111 * pairs.h (SCM_EOL): Delete this definition, equating it with
7113 * tags.h (SCM_EOL): Give it a new definition here; I think I found
7114 the value it used to have. Doc fixes, too.
7116 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
7118 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
7119 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
7120 Lord's implementation of structs, allowing for tail arrays as
7121 described in the manual. Also fixed some bugs. (Both the interface
7122 and the implementation should be improved.)
7124 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
7126 * print.c, print.h: Closures now print like #<procedure foo (x)>.
7127 People who whish to see the source can do `(print-enable 'source)'.
7128 Removed #ifdef DEBUG_EXTENSIONS.
7130 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7132 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
7133 integer (assuming for now accepting an integer is a good thing).
7135 * error.c, fports.c: replace use of %S in lgh_error args with %s.
7136 %S will be used instead for write'ing arguments.
7138 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
7139 asserts. fix a few other asserts.
7140 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
7141 scm_uniform_vector_ref, scm_array_set_x,
7142 scm_dimensions_to_unform_array): change args in
7143 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
7144 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
7145 scm_substring_fill_x): likewise.
7146 gsubr.c (scm_gsubr_apply): likewise.
7147 eval.c (SCM_APPLY): likewise.
7149 * eval.c (4 places): replace scm_everr with lgh_error or
7152 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
7153 scm_memory_error): new procedures.
7154 scm_everr: deleted. can use scm_wta, dropping first two args.
7155 scm_error: convert NULL subr to SCM_BOOL_F.
7157 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
7160 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
7163 * error.c, error.h: new error keys: scm_arg_type_key,
7164 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
7166 scm_wta: reimplement using lgh_error instead of scm_everr.
7168 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
7170 * gdbint.c: scm_lread now has one more argument.
7172 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
7173 scm_port_\1; Added mutator scm_set_port_filename_x (used when
7174 loading source from non-file ports, which, e. g., happens when
7175 using the Emacs interface).
7177 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
7180 * read.c: Added code for recording of positions of source code
7181 expressions; New functions: recsexpr, scm_lreadrecparen;
7182 _scm_make_srcprops --> scm_make_srcprops
7183 (scm_flush_ws): Removed updating of positions counters. This work
7184 is already done by scm_gen_getc
7186 * read.h: Added prototype for scm_lreadrecparen
7188 * print.c: Added #include "alist.h"
7190 * eval.c: Added #include "hash.h"
7192 * eq.c: Added #include "ramap.h"
7194 * options.c: Documentation fixes.
7196 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
7197 (scm_init_srcprop): Adjusted size of initial source-whash. Name
7198 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7199 --> scm_make_srcprops
7201 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7202 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7203 function calls in the definition of the whash access macros.
7205 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7207 * init.c (scm_boot_guile): Add level of indirection to
7208 scm_boot_guile_1() to ensure that stack base pointer is properly
7209 initialized. There was no guarantee that variable i was the
7210 highest/lowest variable on stack (i.e. the call frame of
7211 scm_boot_guile was not completely protected from gc).
7213 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7215 * ports.h (scm_port_table): put back file_name, it will be used to
7216 support debugging. Undo related changes in fports.c, ioext.c,
7219 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7221 * ports.h (scm_port_table): remove file_name member for now, it seems
7223 * fports.c (scm_open_file): don't set file_name in PTAB.
7224 (prinfport): don't use file_name in PTAB.
7225 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7226 * ports.c (scm_add_to_port_table): don't intialize file_name.
7227 (scm_port_file_name): remove for now.
7228 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7230 * fports.h (scm_mkfile): prototype deleted.
7231 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7233 * debug.c, unif.c: use scm_out_of_range instead of
7234 wta for range errors (ASSERT still needs work).
7236 * error.c, error.h (scm_out_of_range): new procedure.
7238 * error.c, error.h (scm_out_of_range_key): new key.
7240 * posix.c (scm_sync): #else was missing.
7242 * error.c, error.h: append _key to names scm_num_overflow and
7245 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
7246 of consing an empty list.
7247 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
7248 of macros, saves code and string space.
7249 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
7250 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
7251 lower case. Rename scm_syserror_m to scm_syserror_msg.
7252 error.h: prototypes for new procedures.
7254 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
7256 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
7258 * error.c, error.h: setup scm_num_overflow key.
7260 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
7261 Remove definition of SCM_OVSCM_FLOW.
7263 * fports.c (scm_open_file): use SCM_SYSERROR_M.
7265 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
7266 explicit message and args.
7268 * error.c, error.h, __scm.h: change system_error_sym to
7271 * error.c (system_error_sym): remove leading %% from the Scheme name
7274 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
7276 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7278 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
7279 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
7280 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
7281 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
7282 renamed. (These were introduced by unsupervised name
7285 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7287 * print.c: Added code for detection of circular references during
7288 printing. (init_ref_stack, grow_ref_stack): New functions. Added
7289 a hook for printing of closures (accessible via print options).
7290 This leads to a split of calls to scm_iprin1 into two classes:
7291 elementary print operations (e. g. the code which prints a smob)
7292 still use scm_iprin1 while top level calls (like scm_display) use
7293 scm_prin1. scm_prin1 begins by clearing the data structure used
7294 to record reference information.
7296 * print.h: Added declarations of scm_prin1 and scm_prlist.
7298 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
7300 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
7302 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
7304 * error.c (err_head): scm_iprin1 --> scm_prin1
7306 * debug.c: Adjusted header comment.
7310 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7312 * strerror.c: Doc fix.
7314 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7316 * gdbint.c (gdb_read): Now possible to run during GC.
7317 (unmark_port, remark_port): New functions.
7319 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7321 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7322 of allocating a new string object. Also, increase size by
7323 the factor 2 instead of 1.5.
7325 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7327 * __scm.h (SCM_P): Corrected to run under traditional C.
7329 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7332 * async.c: Calls to scm_sysintern corrected.
7334 * async.h (scm_async_clock): Redundant declaration removed.
7336 * continuations.c (scm_dynthrow): Redundant declaration removed.
7338 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
7339 Definition typos corrected.
7341 * debug.h: Missing declarations of functions in debug.c added
7344 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7345 Missing declarations to functions in eval.c added.
7347 * filesys.c: Possibly uninitialized variable rv.
7349 * gc.h (scm_object_addr, scm_unhash_name): Missing
7350 declarations of functions defined in gc.c added.
7352 * genio.c: Possible typos str_data -> wstr_data. ???
7354 * genio.c: Possibly unintended shadowing of local variable
7355 `int c' (gotos out of scope of inner `c'). ???
7357 * init.c: Uninitialized `SCM last' may be used.
7359 * ioext.h: (scm_sys_isatty_p): Typo.
7361 * list.h (scm_list_head): Missing prototype for function in
7364 * numbers.c (scm_two_doubles): Changed from extern to static
7365 (is used only within numbers.c).
7367 * numbers.h: Repeated declarations removed.
7369 * ports.h (scm_close_all_ports_except): Declaration for the
7370 function defined in ports.c added.
7372 * posix.h: Missing declarations added.
7374 * procs.h (scm_make_subr_opt): Missing declaration added.
7376 * socket.h (scm_sys_gethost): Missing declaration added.
7378 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7380 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7381 Missing declarations added.
7383 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
7385 * struct.c: Uninitialized variable `SCM answer' may be used.
7387 * unif.c (l2ra): Declaration prototype.
7389 * unif.c (scm_array_equal_p): Dummy definition removed (it is
7390 defined in ramap.c).
7392 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
7393 Redundant declarations removed (they are in ramap.h).
7395 * variable.h (scm_make_udvariable,
7396 scm_make_undefined_variable): Declaration corrected to
7397 correspond variable.c.
7399 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
7400 Missing declarations added.
7402 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
7404 * Makefile.in (distclean): Don't forget to delete fd.h.
7406 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7408 * fd.h.in, tags.h: Trivial cleanups.
7410 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
7411 marksweep.h just declared functions from gc.c.
7412 * gc.h, libguile.h: Don't #include "marksweep.h".
7413 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7414 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
7415 dependencies updated.
7417 * libguile.h: Don't #include "files.h"; it's been deleted.
7419 * files.c (scm_sys_delete_file): Moved to filesys.c.
7420 File is now empty; deleted.
7422 * filesys.c: scm_sys_delete_file is now here. Remove
7423 #if's; they seem to rely on remnants of an old portability
7424 regimen. If the problems come up again, solve them properly,
7425 using autoconf. Specifically: Don't test M_SYSV, and #define
7426 remove to be unlink if it's #defined; don't use remove just
7427 because HAVE_STDC_HEADERS is #defined.
7428 * filesys.h: Add declarations for scm_sys_delete_file.
7429 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7430 files.o, files.h, files.c, and files.x.
7431 * init.c: Don't #include "files.h", and don't call scm_init_files.
7433 Use SCM_P instead of PROTO; the latter intrudes on the user's
7435 * params.h: Deleted; definition of SCM_P moved to...
7436 * __scm.h: ... here, where it replaces PROTO macro.
7437 * libguile.h, smob.h: Don't #include "params.h".
7438 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
7439 smob.h: Fix prototypes accordingly.
7440 * Makefile.in: Update dependencies.
7441 (inner_h_files): Remove params.h.
7443 * gc.c: #include "gc.h"; every module should include its header,
7444 to let the compiler cross-check the declarations against the
7447 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
7448 simpos.h: #include "libguile/__scm.h".
7450 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
7452 * init.c: Don't forget to #include smob.h and init.h.
7453 * Makefile.in: Dependencies updated.
7455 * smob.h: Use PROTO instead of #if __STDC__.
7457 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
7459 * __scm.h: Doc fixes.
7461 * __scm.h, libguile.h: Use "quotes" in the #includes, not
7462 <angles>; this allows `make depends' to work properly.
7464 * libguile.h: #include smob.h and pairs.h before the others; they
7465 define typedefs used by other headers.
7467 C files should #include only the header files they need, not
7468 libguile.h (which #includes all the header files); the pointless
7469 recompilation was wasting my time.
7470 * Makefile.in (all .o dependency lists): Regenerated.
7471 * libguile.h: Don't try to get a definition for size_t here...
7472 * __scm.h: Do it here.
7473 * _scm.h: Since this is the internal libguile header, put things
7474 here that all (or a majority) of the libguile files will want.
7475 Don't #include <libguile.h> here; that generates dependencies on
7476 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
7477 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
7478 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

7575 * weaks.c: Get "weaks.h".
7577 * stackchk.h: #include "libguile/debug.h",
7579 * print.h, read.h: #include "options.h", since everyone who uses
7580 either of these files will need that.
7582 * smob.h: #include "ports.h", "genio.h", and "print.h", since
7583 anyone who uses this file will need them to define the smob
7584 printing functions. Also, get markers.h, since people will need
7585 to #define the mark functions.
7587 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
7588 * ports.h: ... to here.
7590 * ports.h (scm_port_table_size): Explicitly give type as 'int';
7591 don't rely on archaic C default type rules.
7593 * fports.h: #include "libguile/ports.h", since you need that in
7594 order to parse this.
7596 * genio.h: #include "libguile/print.h", because you need that to
7597 parse this; don't bother #including "ports.h", since print.h gets
7600 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
7602 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
7603 this; it's now a reference to an element of *scm_root.
7605 * debug.h: Don't #include "options.h"; the compiler won't be able
7606 to find that once the headers are installed; instead, #include
7607 "libguile/options.h".
7608 * gc.h: Same, with marksweep.h.
7609 * mbstrings.h: Same, with symbols.h.
7610 * scmhob.h: Same, with _scm.h.
7611 * smob.h: Same, with params.h.
7613 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
7614 C files; there's no need for this, and it forces recompilations
7617 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
7619 * error.c (scm_error): declare scm_error_callback.
7621 * error.h: prototype for scm_error_callback.
7623 * __scm.h: define lgh_error.
7624 (SCM_SYSERROR): redefine using lgh_error.
7626 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
7628 * error.c (scm_error): new procedure.
7630 * error.h: prototype for scm_error.
7632 * Makefile.in (install): install scmconfig.h from the current
7633 directory, not $(srcdir).
7635 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7637 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7638 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7639 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
7640 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
7641 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
7642 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
7643 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
7644 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
7645 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7646 vports.h, weaks.h: #include "libguile/__scm.h", not
7647 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
7648 dependencies are within libguile properly.
7650 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7652 * Makefile.in (.c.x): Simplify; there's no need to run this rule
7653 when scmconfig.h doesn't exist.
7655 * load.c (scm_sys_try_load): Correct spelling.
7657 * feature.c (scm_loc_features): Make this static.
7659 * Makefile.in (libpath.h): Omit trailing slash from path. We
7660 shouldn't require it of users, so why put it here?
7662 Move code to initialize and search %load-path from ice-9 to C
7663 code, so we can use the load-path to find the ice-9 boot code;
7664 this makes it easier to run Guile without installing it. See
7665 corresponding changes in guile/Makefile.in.
7666 * feature.c: Move stuff concerned with the load path to load.c.
7667 (scm_compiled_library_path): Deleted.
7668 Don't #include libpath.h here.
7669 * feature.h: Don't mention scm_compiled_library_path.
7670 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
7671 <sys/stat.h>, and <unistd.h> (if present).
7672 (R_OK): #define if the system hasn't deigned to.
7673 (scm_loc_load_path): New variable.
7674 (scm_init_load_path, scm_sys_search_load_path,
7675 scm_sys_try_load_path): New functions.
7676 (scm_init_load): Initialize scm_loc_load_path to point to the
7677 value cell of the Scheme %load-path variable.
7678 * load.h: Add declarations for scm_sys_search_load_path,
7679 scm_sys_try_load_path.
7680 * init.c: Call scm_init_load_path.
7681 * Makefile.in (feature.o, load.o): Dependencies updated.
7683 * load.c, load.h: Rewrite using PROTO macro.
7685 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7687 * gc.c (scm_cellp): New function: C predicate to determine if an
7688 SCM value can be regarded as a pointer to a cell on the heap.
7690 * gc.h: Added declaration of scm_cellp.
7692 * gdb_interface.h: New file: The GDB interface header from the GDB
7695 * gdbint.c: New file: GDB interface.
7697 * gdbint.h: New file: GDB interface.
7699 * libguile.h: Added #include <libguile/gdbint.h>.
7701 * init.c (scm_boot_guile): Added scm_init_gdbint.
7703 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
7704 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
7705 found if object files and source are kept separate).
7707 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
7709 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
7711 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
7713 * configure.in: Don't substitute the values of TCL_SRC_DIR and
7714 TK_SRC_DIR; they're not relevant any more.
7716 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
7717 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
7719 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
7721 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
7722 search path, so we can find the <libguile/MUMBLE.h> headers.
7724 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
7726 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
7727 implicit in the .c.o rule.
7728 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
7731 Put the library path in a header file, instead of passing it on
7732 the command line in every compilation.
7733 * Makefile.in (libpath.h): New target.
7734 (feature.o): Depend on libpath.h.
7735 (clean): Delete libpath.h.
7736 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
7737 * feature.c: ... #include "libpath.h" here.
7738 * .cvsignore: Ignore libpath.h.
7740 Don't install the unwashed masses of Guile header files in the
7741 main #include path; put most of them in a subdirectory called
7742 'libguile'. This avoids naming conflicts between Guile header
7743 files and system header files (of which there were a few).
7744 * Makefile.in (pkgincludedir): Deleted.
7745 (innerincludedir): New variable; this and $(includedir) are enough.
7746 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
7747 (installed_h_files): Divide this up. Now this variable lists
7748 those header files which should go into $(includedir) (i.e. appear
7749 directly in the #include path), and ...
7750 (inner_h_files): ... this new variable says which files appear in
7751 a subdirectory, and are referred to as <libguile/mumble.h>.
7752 (h_files): List them both.
7753 (install): Create innerincludedir, not pkgincludedir. Put
7754 the installed_h_files and inner_h_files in their proper places.
7755 (uninstall): Corresponding changes.
7756 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7757 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7758 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
7759 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
7760 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
7761 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,

7764 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7765 vports.h, weaks.h: Find __scm.h in its new location.
7766 * __scm.h: Find scmconfig.h and tags.h in their new locations
7767 (they're both "inner" files).
7769 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
7771 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
7773 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7775 * posix.c: Doc fixes.
7777 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
7779 * socket.c: Don't include a prototype for inet_aton; just use a
7780 K&R style declaration, to avoid warnings but minimize the chance
7781 of conflicts with the system.
7783 On NextStep, <utime.h> doesn't define struct utime, unless we
7784 #define _POSIX_SOURCE before #including it.
7785 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
7786 * acconfig.h: New comment text for above CPP symbol.
7787 * configure.in: Call it.
7788 * posix.c: #define _POSIX_SOURCE if it seems necessary.
7790 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
7792 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
7793 testing for __EMX__.
7795 * posix.c: #include <libc.h>, if it exists.
7797 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
7798 don't even know if the latter exists.
7800 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
7801 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
7802 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
7804 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
7806 (scm_init_posix): Use them when initializing the Scheme constants
7809 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
7811 * Makefile.in (libdir, includedir, bindir): Use the
7812 autoconf-supplied values, instead of deriving them ourselves.
7813 (pkgincludedir, datadir, pkgdatadir): New variables.
7814 (install, uninstall): Put the header files in a special
7815 subdirectory, not in the main search path.
7817 * Makefile.in (ALL_CFLAGS): Provide the proper value for
7818 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
7820 * Makefile.in (IMPLPATH): Deleted; never used.
7822 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
7823 on the Tcl/Tk source any more.
7824 (INCLUDE_CFLAGS): Remove references to the above.
7826 * Makefile.in (version.o): Corrected dependencies.
7828 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
7830 * libguile.h: #include "version.h"
7832 * init.c (scm_boot_guile): Call scm_init_version.
7833 * gscm.c (gscm_run_scm): Call scm_init_version.
7835 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
7836 GUILE_VERSION): AC_DEFINE these.
7837 (acconfig.h): #undef the above symbols.
7839 * Makefile.in (libobjs): Add version.o.
7840 (installed_h_files): Add version.h.
7841 (c_files): Add version.c.
7842 (gen_c_files): Add version.x.
7843 (version.o): New rule.
7844 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
7845 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
7846 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
7847 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
7848 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
7849 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
7850 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
7851 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,

7853 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
7854 weaks.o): Add version.h to dependency lists.
7855 (markers.o): Remove duplicate rule.
7857 * version.h: New file.
7859 * version.c: New file.
7861 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7863 * symbols.c (scm_strhash): scm_downcase is now a function, not an
7864 array; use it appropriately. Since GCC is quite happy to
7865 subscript functions, it never warned us about this; we should use
7866 -Wpointer-arith in the future. I guess we never tested
7869 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
7871 * socket.c: Doc and copyright fixes.
7873 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7875 * debug.c: Fixed and improved gdb support.
7877 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7879 * socket.c: Added declaration of inet_aton to avoid compiler
7880 warning. (Hope this solution is correct.)
7882 * stime.c: Added declaration of ftime. (This is missing in
7885 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
7887 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
7889 * Makefile.in (c_files): add strerror.c.
7891 * strerror.c: new file from Emacs' sysdep.c.
7892 maybe configure should also check for sys_errlist.
7894 * configure.in (AC_REPLACE_FUNCS): add strerror.
7896 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7898 * debug.c (scm_init_debug): Added initialization for
7899 scm_evaluator_traps.
7901 * debug.h, debug.c: Various name changes.
7902 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
7903 "debug-options-interface". See commentary in options.c.
7905 * options.h, options.c: Options now have documentation strings.
7906 Also added a long explanatory commentary.
7908 * eval.c, print.h, print.c, read.h, read.c: Modifications to
7911 * gscm.c, init.c, root.c, throw.c: Bug fixes:
7912 last_debug_info_frame is now updated in all cases.
7914 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
7917 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7919 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
7920 Added option STACK_CHECKING.
7922 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7924 * Makefile.in: Added {debug,options,srcprop}.{h,c}
7926 * __scm.h: Removed symbols for debugging support.
7928 * acconfig.h: Added symbols for debugging support.
7930 * configure.in: Added user option for debugging support.
7931 --enable-debug will include the debugging code into libguile.a.
7933 * continuations.c (scm_make_cont): Enlarged the #if 0 around
7934 scm_relocate_chunk_to_heap.
7936 * debug.c: New file: low-level debugging support. It also
7937 includes support for debugging with gdb. (The extensions to gdb
7938 are written by Per Bothner at Cygnus.)
7940 * debug.h: New file: low-level debugging support.
7942 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
7943 argument pairs. Extensive modifications to the debugging
7944 evaluator. Added "SECTION:" commentaries to clarify what happens
7945 when, during double compilation. Renamed EVALIMP --> EVALIM.
7946 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
7947 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
7948 the beginning of the file. New procedure: scm_unmemocopy.
7949 Added some global state variables needed by the debugging
7950 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
7951 check_entry, check_apply, check_exit, debug_options and
7952 evaluator_traps. New acro: undefine.
7954 * eval.h: Renamed EVAL --> XEVAL.
7956 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
7957 --> scm_make_weak_key_hash_table.
7959 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
7960 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
7962 * libguile.h: Conditionally include debug.h
7964 * objprop.c (scm_object_properties, scm_set_object_properties_x):
7965 scm_object_properties shouldn't return handle. `handle' now gets
7966 initialized in scm_set_object_properties_x. scm_object_properties
7967 doesn't any longer create an entry in scm_object_whash.
7969 * options.c: New file: handling of run time options.
7971 * options.h: New file: handling of run time options.
7973 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
7975 * print.c: New procedure: scm_print_options
7977 * print.h: Defines for print options.
7979 * read.c: New procedure: scm_read_options
7981 * read.h: Defines for reader options.
7983 * root.h: Added scm_source_whash among scm_sys_protects.
7985 * srcprop.c: New file: source properties.
7987 * srcprop.h: New file: source properties.
7989 * throw.c (jbsmob): Jump buffers are now correctly allocated.
7990 (Bug found by A. Green.)
7992 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
7994 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
7996 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
7998 * libguile.h: #include "objprop.h"; I guess this was forgotten.
8000 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
8001 and should be called by the final client.
8003 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
8005 * gc.h: Use the PROTO macro when declaring functions.
8006 * gc.c: Use the PROTO macro when declaring static functions.
8007 Remove the CPP hair around function definitions.
8009 * gc.c (scm_init_storage): Initialize scm_asyncs.
8011 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
8012 preprocessor symbol; "__scm.h" is where it might get #defined.
8013 * __scm.h: Similar: #include <scmconfig.h> before testing
8016 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
8018 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
8020 * init.c (scm_boot_guile): Add init_func argument; call
8021 (*init_func) instead of calling scm_appinit; it's ucky to
8022 hard-code names for the user's procedures.
8023 * init.h (scm_boot_guile): Adjust declaration.
8025 * __scm.h (PROTO): New macro, for declaring functions with
8028 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
8029 eliminate all the __STDC__ conditionals.
8030 (scm_boot_guile): Add declaration.
8031 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
8032 Remove __STDC__ conditionals around function definitions; the
8033 declarations in init.h will provide the same information, more
8036 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
8037 complain about it in the error message; the error message is
8038 adequate without that note, and there's nothing the user can do
8041 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
8043 * Makefile.in (ancillary): Drop def.sed.
8045 * posix.c (scm_init_posix): Use numeric values, rather than
8046 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
8047 F_OK. The symbols aren't available on some systems, and I'm
8048 pretty sure their values are fixed by common widespread practice.
8049 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
8051 More functions unavailable on some systems.
8052 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
8053 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
8055 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8056 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
8057 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
8058 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
8059 stub that signals an error as the #else.
8061 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
8063 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
8065 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
8067 * unif.c: include ramap.h.
8069 * read.c (endif): case_insensative_p renamed case_insensitive_p.
8071 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
8073 * ports.c: include sys/ioctl.h.
8075 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
8077 * configure.in: check for sys/ioctl.h.
8079 * ports.c: include <malloc.h> not "malloc.h".
8081 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8083 * fports.c: remove ttyname and tmpnam declarations.
8085 * posix.c: fewer ttyname declarations.
8087 * fports.c: include <string.h> not "string.h".
8089 * init.c, ioext.c: include string.h and unistd.h.
8091 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8093 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
8094 genio.c, simpos.c, vports.c: include string.h.
8096 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
8098 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
8100 (scm_addr_buffer_size): change type from scm_sizet to int.
8101 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
8102 from scm_sizet to int.
8104 * error.c: include unistd.h.
8106 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
8109 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
8111 * __scm.hd, def.sed: deleted.
8113 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
8115 Changes for NeXT, suggested by Robert Brown.
8116 * configure.in: Call AC_TYPE_MODE_T.
8117 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
8118 NeXT. Put header file list in alphabetical order.
8119 * configure, scmconfig.h.in: Regenerated.
8120 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
8122 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
8125 * acconfig.h: New file, providing documentation for the CPP
8126 symbols defined in configure.in
8127 * acconfig-1.5.h: Removed; superceded by the above.
8129 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
8131 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
8133 * fports.c (scm_open_file): don't return #f, throw error.
8135 * ioext.c (fileno): renamed from %fileno.
8136 (soft-fileno): deleted.
8138 * ports.c (scm_port_revealed): don't need to check for -1 from
8140 (scm_set_port_revealed_x): return unspecified, not #f.
8142 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
8144 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
8146 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
8148 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
8150 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8152 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
8153 This is necessary on Ultrix, and doesn't hurt portability.
8155 * Makefile.in (dist-dir): New target, implementing a new dist system.
8156 (installed_h_files): Put in alphabetical order.
8157 Remove duplicate entries for markers.h and unif.h.
8158 (c_files): Remove duplicate entries for markers.c.
8159 (ancillary): Renamed from anillery; all uses changed. Remove
8160 PLUGIN; it's a directory, and needs special treatment in dist-dir.
8161 Remove all the ../doc/* files; doc/Makefile.in handles that.
8163 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
8165 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
8166 every if must have an else, or else the whole command has a
8167 non-zero exit code whenever the if's condition is false.
8169 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
8171 * posix.c: include string.h.
8173 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
8175 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
8178 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
8179 Remove leading % from scheme names.
8180 Do not return error values, call SCM_SYSERROR or similar.
8182 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
8184 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
8186 * struct.c (scm_init_struct): new file.
8188 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
8190 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
8191 (scm_list_head): added list-head for rapidly chopping argument
8192 lists off of longer lists (and similar).
8194 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
8196 * objprop.c (scm_object_property): assq the cdr of the whash
8197 handle for obj, not the handle itself.
8199 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
8201 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
8202 weak hash tables last of all marking to avoid an obscure gc bug.
8203 WARNING: circular lists stored in a weak hash table will hose us.
8205 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
8207 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
8208 new functions similar to scm_substring_move_left_x and
8209 scm_substring_move_right_x.
8211 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
8213 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
8216 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
8218 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
8220 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
8222 * strports.c (scm_strprint_obj): convenience function. C for
8223 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
8225 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
8226 removed to a separate library
8228 * init.c (scm_boot_guile): copied from guile-tcl.c.
8229 Initialization specific to tcl interpreters removed.
8231 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
8233 * ports.c (scm_ports_prehistory): size malloced here doesn't
8234 matter so long as it is non-0 (got rid of "* 4").
8236 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
8238 * gscm.h: gscm_mkarray eliminated (presumably was not being used
8239 since its definition was bogus).
8241 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
8243 * mallocs.[ch]: back again (for rx at least).
8245 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
8247 * ports.c: removed functions relating to the mapping between ports
8248 and descriptors. (That stuff is unix-specific and should be collected
8249 in a separate library).
8251 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
8252 (Tom Mckay@avanticorp.com)
8254 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
8256 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
8257 handled correctly (SCM_FREEP was applied to them) -- test for
8258 NIMP. Keys in weak hash tables were spuriously (though harmlessly)

8426 initialization to fix a race condition.
8428 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
