1 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
3 * fports.c (fport_write): use memcpy instead of strncpy, in case
6 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
8 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
10 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
11 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
12 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
13 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
14 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
15 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
16 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
17 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
18 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
19 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
20 scm_sym_ as prefix for symbols.
22 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
24 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
25 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
26 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
27 scm_sym_atcall_cc): Made global.
29 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
31 * eval.c (scm_sym_args): Made global.
33 * objects.c (scm_set_object_procedure_x): Disallow setting of
34 procedures for pure generic functions.
36 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
38 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
39 Scheme name from lseek to seek, but lseek was added recently so
40 it shouldn't be a big problem.
41 * ports.c, gdbint.c, ioext.c: changed callers.
43 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
45 * fports.c (fport_input_waiting): if select is used, return 1
46 instead of whatever FD_ISSET expands to. maybe it will be useful
47 to interpret the value from the input_waiting ptob procedure as a
48 lower bound on the number of bytes available.
50 * Mikael asked for a few names to be changed...
52 * ports.c (scm_make_port_type): take the write procedure as the
53 second argument instead of the flush procedure.
54 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
55 fflush -> flush, read_flush -> end_input, fclose -> close,
56 fill_buffer -> fill_input, ftruncate -> truncate,
57 input_waiting_p -> input_waiting.
59 * ports.c (end_input_void_port): was read_flush_void_port.
60 (scm_set_port_end_input): was scm_set_port_flush_input.
61 (scm_set_port_flush): was scm_set_port_write.
62 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
63 (scm_end_input): was scm_read_flush.
64 (scm_fill_input): was scm_fill_buffer.
65 (scm_flush): was scm_fflush.
66 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
67 (fport_end_input): was local_read_flush.
68 (fport_flush): was local_fflush.
69 (fport_close): was local_fclose.
70 (fport_truncate): was local_ftruncate.
71 (fport_seek): was local_seek.
72 (fport_free): was local_free.
73 (fport_fill_input): was fport_fill_buffer.
74 * strports.c (st_end_input): was st_read_flush.
75 (st_truncate): was st_ftruncate.
76 * vports.c: (sf_flush): was sfflush.
77 (sf_close): was sfclose.
78 (sf_fill_input): was sf_fill_buffer.
80 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
84 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
86 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
87 forms now contain the expressions to be dispatched upon instead of
88 depending on a surrounding lambda or let; Generic function
89 dispatch has been optimized; `apply' on a generic function now
90 works a little bit strangely. It uses a trick so that the type
91 dispatch code in SCM_CEVAL can be reused.
93 * objects.h, objects.c (scm_apply_generic_env): Added (used by
95 (scm_operator_p): Added.
96 (scm_sym_atdispatch): Added.
97 (scm_set_object_procedure_x): Modified to handle the new style
99 (scm_object_procedures): New debugging procedure.
101 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
103 * eval.c, eval.h (scm_sym_args): Added.
105 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
107 * feature.c, feature.h (scm_c_run_hook): Added.
109 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
110 cdrxnoap and loopnoap instead of begin and loop.
112 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
114 * ports.c (scm_putc, scm_puts),
115 * unif.c (scm_uniform_array_write): use scm_lfwrite.
116 * ports.c (scm_putc): change type of first argument from int to char.
118 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
120 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
121 SCM_IM_HASH_DISPATCH.
123 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
124 (scm_si_redfined, scm_si_hashsets): Moved.
126 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
127 flag which combines type and status info so that the class
128 redefinition protocol has zero cost during normal execution.
130 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
132 * ports.h (scm_ptob_descriptor): include a write procedure again.
133 it's more efficient for unbuffered fports (e.g., sockets.)
135 * ports.c (scm_puts): use ptob->write.
136 * vports.c (scm_make_sfptob): set write proc in ptob.
137 * strports.c (scm_make_stptob): set write proc in ptob.
138 * ports.c (write_void_port): new procedure.
139 * vports.c (sf_write): new procedure.
140 * ports.c (scm_lfwrite): use ptob->write.
141 * strports.c (st_write): new procedure.
142 * fports.c (fport_write): new procedure.
143 (scm_make_fptob): set write in ptob to fport_write.
144 * ports.h: prototype for scm_set_port_write.
145 * ports.c (scm_make_port_type): initialise ptob write procedure.
146 (scm_set_port_write): new proc.
148 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
150 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
151 until we've verified that it is actually a port. (Thanks to
154 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
156 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
157 code, particularly an unnecessary test (len != size, where len ==
158 size). (Was this leftovers from debugging code, or have I missed
161 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
162 size. (Thanks to James Dean Palmer.)
164 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
165 (Thanks to Lorentey Karoly.)
167 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
169 * eval.c (scm_m_expand_body): Use scm_cons_source.
171 * struct.c (scm_print_struct): Use vtable name.
173 * print.c (scm_init_print): Set name of print state type.
175 * stacks.c (scm_init_stacks): Set name of stack type.
177 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
179 * eval.c (SCM_CEVAL): Removed old implementation of internal
182 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
184 * debug.c, debug.h (scm_reverse_lookup): Added.
185 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
186 internal procedure definitions; Don't use scm_i_inner_name.
188 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
191 * eval.h: Added prototypes for multi language support functions.
193 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
194 improper lists in the low-level representation, since that will
195 cause a begin to be prepended at macro expansion.
197 * eval.c (scm_cons_source): Version of cons which copies source
198 properties from an existing cell.
199 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
201 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
202 procedure source before calling scm_unmemocopy instead of faking
205 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
207 Ported `internal defines' fix from SCM. Original ChangeLog entry:
209 1998-07-09 Radey Shouman <radey@colorage.com>
211 * eval.c (ceval_1): Modifications to allow rewriting of interal
212 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
213 body of which it is the CAR is macro expanded by m_expand_body,
214 which rewrites internal DEFINE.
216 (m_expand_body): Added.
218 (m_macroexp1): Added argument to control error checking:
219 m_expand_body may speculatively expand forms in the wrong
220 environments. Made argument number checks conditional on
223 (m_body): Added, error checks bodies and inserts the ISYM tokens.
225 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
228 (m_cond): (m_case): (m_quote): Modified to avoid destructively
229 changing their argument forms. Since m_expand_body
230 speculatively macro expands forms the process must be
233 (m_ident_eqp): Fixed to use proper environment.
235 (renamed_ident): Added DEFER_INTS_EGC.
237 Added prototypes for static functions.
243 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
244 is false, do not produce an error for unbound variables, return a
245 pointer to cell_undef instead.
247 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
251 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
252 destructively changing their argument forms. Since m_expand_body
253 speculatively macro expands forms the process must be reversible.
255 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
256 SCM_IM_LET introduced by named lets.
258 (scm_m_letstar): Use scm_m_body instead of bodycheck.
260 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
261 scm_letrec. scm_letrec1 does not check for a null binding and
262 takes an additional argument to specify the ISYM of the body. Use
263 scm_m_body instead of bodycheck.
265 (scm_m_let): Use scm_m_body instead of bodycheck.
267 (scm_m_expand_body, scm_macroexp): New.
269 (unmemocopy): Account for ISYMs introduced by scm_m_body.
271 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
272 check=1. Throw error for internal defined that have not been
273 rewritten by scm_m_expand_body.
275 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
276 Removed prototype for SCM_APPLY.
278 * tags.h: Added extern declaration of scm_isymnames.
280 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
282 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
284 * lang.c: New file: Beginning of multi-language support.
286 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
288 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
289 (scm_dynamic_wind): Added argument checking for the after guard so
290 that we don't add garbage on the dynwind chain.
291 (scm_swap_bindings): Added.
293 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
294 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
295 (scm_isymnames): New isyms for multi-language support.
297 * eval.c (scm_nil, scm_t): New symbols.
298 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
299 forms for multi-language support.
301 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
303 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
305 Renamed functions in the random function library interface
306 from scm_i_XXX --> scm_c_XXX.
308 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
310 * ports.c (scm_putc): fix line-buffering.
312 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
314 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
315 scm_set_ptob_XXX --> scm_set_port_XXX.
317 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
319 * ports.c, ports.h (scm_make_port_type): New interface for
320 creation of port types (replaces scm_newptob). Just as for the
321 smobs, we need to separate the internal representation of smob
322 types from the interface, so that we easily can add new fields and
323 rearrange things without caring about backward compatibility.
324 This change was forced by the need in GOOPS to create classes
325 representing port types.
326 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
327 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
328 scm_set_ptob_seek, scm_set_ptob_truncate,
329 scm_set_ptob_input_waiting_p): New setters.
330 (scm_newptob): Rewritten to use scm_make_port_type. For backward
332 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
333 (scm_prinport): Removed.
334 (scm_port_print): Added.
335 (scm_print_port_mode): Added.
336 (void_port_ptob, print_void_port, close_void_port, noop0):
337 Removed. Removed #include "genio.h" Added #include "objects.h",
340 * fports.c (prinfport): Moved code from ports.c.
342 (scm_fptob): Removed. Instead use new interface.
343 (scm_make_fptob): Added. (Need to create basic ports in a
344 specific order in ports.c.)
346 * strports.c (scm_stptob, prinstpt, noop0): Removed
347 (scm_make_stptob): Added.
349 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
350 (scm_make_sfport): Added.
352 * filesys.c (scm_dir_print): Don't use the port printing code.
353 Instead provide specific directory printer.
355 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
357 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
360 * smob.c (scm_smob_print): Handle non-existing type name nicely.
361 Removed #include "genio.h"
363 * objects.c (scm_make_port_classes): New function ptr.
365 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
367 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
369 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
370 allow the 1st argument to be a fdes or filename as well as a
371 port (as in the filesys.c version).
373 * filesys.c (scm_truncate_file): removed.
375 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
377 * readline.c, readline.h: Removed.
379 * objects.c, objects.h (scm_port_class): Added.
380 (scm_class_of): Look up port class in scm_port_class.
381 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
382 SCM_INOUT_PCLASS_INDEX): Added.
385 * Makefile.am: Removed genio.c, genio.x.
389 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
391 * init.c: Make sure that scm_post_boot_init_modules is called only
392 once. (Important when using a dumped image.; Thanks to Bernard
395 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
397 * guardians.c (scm_guardian_zombify): Separate scanning for
398 zombies from marking the pairs of the free list.
400 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
401 use the macros. (Thanks to Michael Livshin.)
403 * eval.c (scm_m_lambda): Let bodycheck check the body of the
404 lambda. Let your sins be purified by the blood of the lambda.
405 (Thanks to Eric Hanchrow.)
407 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
408 (Thanks to Valdis Kletnieks.)
410 Fixes for EMX from Mikael Ståldal.
412 * filesys.c: #include <io.h>, if we have it.
413 * scmconfig.h.in: Regenerated.
415 * stime.c (ftime): Delete declaration for this function --- let
416 the system supply it.
418 Cleanups from John Bley.
420 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
422 * gsubr.c: Don't include "gsubr.h" twice.
424 Cleanups for compilation on Irix 6, from David Kaelbling.
426 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
427 regex_t pointer. This is what the callers have, mostly.
428 (scm_regexp_exec): Don't forget to pass the `rx' argument to
429 scm_regexp_error_msg.
431 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
432 int. That way, if we get a warning on this line, it's more likely
433 that we're really missing bits we care about.
435 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
438 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
439 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
440 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
441 cast at all is more appropriate in every case. At the moment, we
442 assume everywhere that SCM is an integral type anyway.
444 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
446 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
447 read_pos after scm_fill_buffer.
449 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
452 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
453 fports.c (fport_fill_buffer): implement the interface change.
455 * ports.c (scm_fill_buffer): interface change: no longer increments
456 read_pos past the character that's returned. it seems clearer to
457 leave it to the caller to decide what to do (thanks Jim).
459 * vports.c (sf_fill_buffer): put the read char into the buffer
460 as well as returning it.
462 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure
465 1999-07-13 Gary Houston <ghouston@easynet.co.uk>
467 * strports.c (scm_strprint_obj): simplify. start with initial
469 (st_seek): don't allow string to be extended if seeking past
470 the end of a read-only port.
472 1999-07-12 Gary Houston <ghouston@easynet.co.uk>
474 * strports.c (st_seek): change the resize checks.
476 * ports.c (scm_ftruncate): throw error if offset works out negative.
478 * strports.c (st_flush): increase string size in blocks of
479 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
480 it's greater and reset read_buf_size.
481 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
482 to be maintained for output ports too (it holds the written
483 part of the string, while write_buf may have unwritten buffer
485 (st_truncate): rewritten.
486 (top of file): added a few notes.
488 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
490 Patch from Greg Badros:
491 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
492 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
493 (function pointer) argument to scm_make_gsubr and scm_make_subr
494 calls. This avoids warnings in C++ programs using guile-snarf.
496 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
498 * strports.c (st_grow_port): set pt->read_pos. set
499 pt->read_buf_size one less than pt->write_buf_size if there's
500 an unwritten char at the end of the string. similarly for
502 (st_resize_port): renamed from st_grow_port.
503 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
504 seek from read_end instead of write_end for SEEK_END.
505 (st_ftruncate): calculate current length using readbuf, not write
507 (scm_strport_to_string): use read_buf_size for length.
508 (stfill_buffer): don't re-initialise the readbuf.
510 1999-07-05 Gary Houston <ghouston@easynet.co.uk>
512 * strports.c (scm_strport_to_string): new procedure.
513 (scm_call_with_output_string, scm_strprint_obj): use
514 scm_strport_to_string.
515 used SCM_INUM0 instead of SCM_MAKINUM (0) in a few places.
517 1999-07-08 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
519 * symbols.c (scm_gensym): Bugfix. (Thanks to Johannes Hjorth.)
521 Fri Jun 25 22:14:32 1999 Greg Badros <gjb@cs.washington.edu>
523 * smob.c: added scm_make_smob_type_mfpe (), scm_set_smob_mfpe ();
524 use scm_make_smob_type_mfpe to initialize "free", "flo", "bigpos",
525 and "bigneg" smob types.
527 * smob.h: Add do ... while(0) idiom to SCM_NEWSMOB. Added
528 SCM_RETURN_NEWSMOB macro. Added protos for new functions in
531 * *.c: Use scm_make_smob_type_mfpe, instead of scm_newsmob, and

752 instead of stepping through an array.
753 (scm_gc_sweep): Update offset used to find start of weak vector to
755 (scm_init_storage): Set scm_weak_vectors to EOL.
757 Fix from Ken Raeburn <raeburn@raeburn.org>:
758 * gc.c (already_in_gc): New variable.

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

779 ChangeLog entries and the patch from two different places...
781 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
783 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
784 it shows up as terrible performance, as we GC constantly.
786 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
787 newline. A bit faster, and definitely hairier.
788 (scm_read_line): Count newlines here instead.
790 * strings.c (scm_take_str): New function.
791 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h

802 and there's a newline to be written, flush the port.
804 Gary Houston's open-buffer port patches:
806 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
808 * ports.c: (scm_lseek): clear buffers even if just reading current
811 * fports.c (local_fclose): call local_fflush unconditionally.

817 strports.c: take care of rw_active and rw_randow.
818 fports.c: scm_fport_drain_input: removed. do it all in ports.c.
819 strports.c (scm_mkstrport): check that pos is reasonable.
820 ioext.c (scm_ftell, scm_fseek): use lseek.

829 fports.h (scm_port): change size types from int to off_t.
830 ports.c (scm_init_ports): initialise the seek symbols here
831 instead of in ioext.c.
832 strports.c (scm_call_with_output_string): start with an empty
833 string, so seek and ftruncate can be used.
835 gdbint.c: adjust string port usage.
837 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
839 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
840 equivalent to fflush for the read buffer.
841 * ports.c (scm_newptob): set read_flush.
842 ports.c (void_port_ptob): set read_flush.
843 fports.c (local_read_flush): new proc. add to ptob.
844 strport.c (st_read_flush): likewise.
845 vport.c (sf_read_flush): likewise.

847 left but fdes. leaving it as a struct to allow for future changes.
848 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
849 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
850 ptob proc if the read buffer is filled.
852 1999-04-23 Gary Houston <ghouston@easynet.co.uk>

855 reading and writing members with rw_active member.
856 SCM_PORT_READ/SCM_PORT_WRITE: new values.
858 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
860 * ports.h (struct scm_port_table): add writing and reading members
861 to replace write_needs_seek: it isn't good enough for non-fports.
862 ports.c, ioext.c, fports.c: corresponding changes.
863 (struct scm_port_table): give it a typedef and rename to scm_port.
864 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
865 corresponding changes.
867 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
869 * ports.c (scm_newptob): bugfix: set seek member.
870 * * (scm_lseek): new procedure, using code from ioext.c:scm_fseek

875 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
876 signals (it was only being done for handlers installed from Scheme).
877 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
878 waiting for input caused an EINTR error from read.
880 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
882 * ports.h (struct scm_port_table): make all the char members
883 unsigned, so they convert to int without becoming negative if large.
885 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
887 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
888 with threads enabled. rename this procedure to
889 fport_wait_for_input and take a port instead of a fdes.
890 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
892 * readline.c (scm_readline): Applied a patch from Greg Harvey to
893 get readline support working again: use fdopen to get FILE objects.
895 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
897 * gc.c (scm_init_storage): install an atexit proc to flush the
899 (cleanup): the new proc. it sets a global variable which can be
900 checked by the ptob flush procs to avoid trying to throw
901 exceptions during exit. not very pleasant but it seems more reliable.
902 * fports.c (local_fflush): check terminating variable and if set
903 don't throw exception.
904 * CHECKME: that the atexit proc is installed if unexec used.
906 * throw.c (scm_handle_by_message): don't flush all ports here.
907 it still causes bus errors.
909 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
912 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
914 * ports.c (scm_char_ready_p): check the port buffer and call the
915 ptob entry if needed.
917 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
918 ptob initialisers. use it in char-ready
920 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
922 * vports.c (sfflush): modified to write a char (since softports
923 currently use shortbuf.)
925 * fports.c (scm_standard_stream_to_port): moved to init.c and
928 * init.c (scm_init_standard_ports): make stdout and stderr
929 unbuffered if connected to a terminal. with stdio they
930 were line-buffered by default.
932 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
935 * ports.h (scm_ptobfuns): change fflush return to void.
936 change flush proc definitions.
938 * strports.c (scm_call_with_output_string): get size from
939 buffer instead of port stream.
940 (st_flush): new proc.
942 * ports.h (struct scm_port_table): added write_end member,
943 as an optimisation. set it where write_buf_size is set.
945 * ports.h (struct scm_port_table): change stream from void *
946 back to SCM. SCM presumably must be large enough to hold a
947 pointer (and probably vice versa but who knows.)
948 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
950 (scm_puts): rewritten
951 * fports.c (local_ffwrite, local_fputs): removed.
952 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)

963 * ports.h (scm_ptobfuns): add seek function pointer.
964 * fports.c: set it to local_seek, new procedure.
967 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
968 use ptob for seek. take ptob instead of fport arg.
970 * ports.h (struct scm_port_table): new member write_needs_seek,
971 replaces reading member in fport struct.
973 * vports.c (sfgetc): store the getted char into the buffer.
974 rename to sf_fill_buffer and install it for fill-buffer in ptob.
975 the Scheme interface is still a procedure that gets a char.
976 (scm_make_soft_port): set up the port buffer (shortbuf).
978 * fports.c (local_fgetc, local_fgets): deleted.
979 * strports.c (stgetc): likewise.
980 * ports.c: scm_generic_fgets: likewise.
982 * ports.h (scm_ptobfuns): add fill_buffer.
983 * ports.c (scm_newptob): assign it.
984 * strports.c (scm_mkstrport): set up the buffer.
985 put just the string into the stream, not cons (pos stream).
986 (stfill_buffer): new proc.
988 * ports.h: fport buffer moved into port table: to be
989 used for all port types.
991 1998-12-20 Gary Houston <ghouston@easynet.co.uk>

998 scm_getpeername, scm_recv, scm_send, scm_recvfrom,
1000 use SCM_FPORT_FDES. use SCM_OPFPORTP not SCM_FPORTP.
1002 * posix.c (scm_getgroups): use SCM_ALLOW/DEFER_INTS.
1003 (scm_ttyname): use SCM_FPORT_FDES.
1004 (scm_tcgetpgrp, scm_tcsetpgrp): likewise.
1006 * filesys.c (scm_chown): use SCM_FPORT_FDES.
1007 (scm_chmod, scm_stat, scm_truncate_file: likewise.
1009 * ioext.c (scm_isatty_p): use SCM_FPORT_FDES.
1010 (scm_fdes_to_ports): modified.
1011 (scm_fdopen): use scm_fdes_to_port.
1013 * ports.c (scm_init_ports): don't try to flush ports using
1014 atexit(). it's too late, errors will cause SEGV.
1016 * fports.c (scm_fport_buffer_add): new procedure.
1018 * fports.h (SCM_FDES_RANDOM_P): new macro. use it in
1019 scm_fdes_to_port and scm_redirect_port.
1021 * ioext.c (scm_redirect_port): use setvbuf to set buffers in the
1022 new port. reset fp->random.

1025 filesys.c (scm_opendir):
1026 restore defer interrupts while the port is constructed.
1027 * (scm_setvbuf): if mode is _IOFBF and size is not supplied,
1028 derive buffer size from fdes or use a default.
1029 (scm_fdes_to_port): use setvbuf instead of creating the buffers
1032 vports.c (various places): use SCM_SSTREAM.
1033 strports.c: likewise.
1034 * gdbint.c: likewise.
1035 * ports.h (SCM_SSTREAM): new macro.
1037 * fports.c (scm_input_waiting_p): use scm_return_first, since port
1038 may be removed from the stack by the tail call to scm_fdes_waiting_p.
1040 * fports.h (SCM_CLEAR_BUFFERS): new macro.
1042 * filesys.c (scm_fsync): use SCM_FDES.

1184 * strop.c (scm_string_capitalize_x): Use the SCM object `s' in

1188 * strop.c (scm_substring_move_x): New function, which can handle
1189 arbitrary overlapping substrings.

1320 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1322 Most of this batch of changes is about how to deal with extended
1323 types when an object system is loaded into Guile. A nice object
1324 system is capable of representing Guile's types as class objects.
1326 For example, we want a regular expression to be of class <regex>.
1327 But regular expressions are smobs which aren't under direct
1328 control of the object system, so there has to be some mechanism
1329 which informs the object system that a new class should be created
1330 which can represent the smob type. I call this a "wrapper class".
1332 * objects.c: #include "smob.h";
1333 (scm_class_keyword): Removed. (Class is automatically created by
1335 (scm_smob_class): Array of smob classes indexed by smobnum.
1336 (scm_make_extended_class): "Plugin" function pointer for creation
1337 of wrapper classes for smob and struct types.
1338 (scm_class_of): Handle compiled closures. (Currently regarded as
1340 Use scm_smob_class to handle smob types;
1341 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
1342 through scm_smob_class;
1345 * smob.c (scm_newsmob): Also create a wrapper class if
1346 scm_smob_class has been initialized.
1348 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
1349 type code and smobnum.
1351 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
1352 (scm_struct_table): Weak key table with auxilliary information for
1353 struct types. Currently used for names and wrapper classes.
1354 (scm_struct_ihashq): Hash function for structs.
1355 (scm_struct_create_handle): Get/create entry in scm_struct_table.
1356 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
1357 for accessing names of vtables. The record implementation in
1358 boot-9.scm currently uses the setter to record the name of record
1359 types. When the object system is initialized, it can use this
1360 information to create wrapper classes with suitable names.
1361 (scm_init_struct): Allocate scm_struct_table.
1362 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
1363 (struct tags are a finite resource and we might want to restrict
1364 the use of tags to vtables only. E.g., Goops only uses tags for
1366 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
1368 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
1371 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
1372 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
1373 Used for access of struct table entries.
1375 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
1376 (scm_hash_fold): New procedure. Used to process all entries in a
1377 hash table (in no particular order).
1379 Argh! For the umpteenth time I got compilation errors because of
1380 the "intuitive" name `kw'. This has to have an end:
1382 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
1383 "kw" --> "keywords" everywhere.
1384 (I doubt that this will cause big compatibility problems since the
1385 application interface is unaffected.)
1387 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
1389 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1391 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
1392 column inums to native form.
1394 Improvement of backtraces: Introduces a new stack narrowing
1395 specifier, #t, for the inner cut. (See further in the comments in
1396 stacks.c:narrow_stack ().)
1398 * procprop.c, procprop.h (scm_sym_system_procedure): New symbol.
1399 (Used to flag certain system procedures which shouldn't turn up in
1402 * eval.c (scm_sym_system_module): New symbol. (Used to flag
1403 modules which aren't "user" modules and the code of which
1404 shouldn't turn up in backtraces.)

1414 * debug.c (scm_procedure_name): Use name property in the default
1417 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
1419 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
1421 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
1422 procedure throughout.
1424 * print.c (scm_iprin1): Removed extraneous space when printing
1425 procedure-with-setters.
1427 Entity and operator setter slots were introduced as a complement
1428 to the <procedure-with-setter> type in order to support entities
1429 and operators with setters in a reasonable and efficient way.
1430 * procs.c (scm_procedure, scm_setter): Handle entity and operator
1433 * objects.h (SCM_OPERATOR_SETTER, SCM_ENTITY_SETTER): New macros.

1443 1999-03-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1445 * objects.h (SCM_OBJ_CLASS_REDEF): New macro: Find class slots
1446 directly through the instance.
1448 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
1450 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
1451 scm_struct_i_flags instead of scm_vtable_index_layout!
1453 * list.c (scm_list_star): New procedure.
1455 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1457 * debug.c (scm_init_debug): Added scheme level constant

1474 Readline paren matching from Greg Harvey, with modifications from
1477 * readline.c (in_readline, reentry_barrier_mutex): Make these
1480 * readline.c: #include <sys/time.h> and "iselect.h", so we can
1481 control how long we're paused, and threads will run while we're
1483 (match_paren, find_matching_paren, init_bouncing_parens): New
1485 (scm_init_readline): Call init_bouncing_parens.

1540 * print.c (scm_iprin1): Use scm_procedure_name instead of
1541 scm_procedure_property for compiled closures.
1543 * tags.h (scm_tc7_pws): New procedure type. Four representations
1544 for procedure-with-setters were considered before selecting this
1547 1. A closure where the CODE and ENV slots are used to represent
1548 the getter and a new SETTER slot is used for the setter. The
1549 original getter is stored as a `getter' procedure property. For
1550 closure getters, the CODE and ENV slots contains a copy of the
1551 getter's CODE and ENV slots. For subr getters, the CODE contains
1554 2. A compiled closure with a call to the getter in the cclo
1555 procedure. The getter and setter are stored in slots 1 and 2.
1557 3. An entity (i.e. a struct with an associated procedure) with a
1558 call to the getter in the entity procedure and the setter stored
1559 in slot 0. The original getter is stored in slot 1.
1561 4. A new primitive procedure type supported in the evaluator. The
1562 getter and setter are stored in a GETTER and SETTER slot. A call
1563 to this procedure type results in a retrieval of the getter and a
1564 jump back to the correct eval dispatcher.
1566 Representation 4 was selected because of efficiency and
1569 Rep 1 has the advantage that there is zero penalty for closure
1570 getters, but primitive getters will get considerable overhead
1571 because the procedure-with-getter will be a closure which calls
1574 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
1575 <procedure-with-setter>, but together with rep 2 it suffers from a
1576 three level dispatch for non-GOOPS getters:
1578 cclo/struct --> dispatch proc --> getter
1580 This is because the dispatch procedure must take an extra initial
1581 argument (cclo for rep 2, struct for rep 3).
1583 Rep 4 has the single disadvantage that it uses up one tc7 type
1584 code, but the plan for uniform vectors will very likely free tc7
1585 codes, so this is probably no big problem. Also note that the
1586 GETTER and SETTER slots can live directly on the heap, using the
1587 new four-word cells.

1619 consistency of name correspondence between Scheme and C;
1620 Renamed scm_i_set_x --> scm_sym_set_x and made global.
1621 Renamed s_set_x --> scm_s_set_x and made global.

1658 from first arg before equal elements in second arg in result.
1659 (scm_merge_list_step): Bugfix: Don't presume that arguments in a C
1660 function call are executed in a well defined order.
1662 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
1664 * alloca.c (alloca): Cast value returned by malloc. (Thanks to
1667 1999-01-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1669 * random.c: Removed alloca includes.
1671 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
1673 * Makefile.in: This changed, for some reason I don't really
1674 understand, when I ran automake in the top level directory. This
1675 may be contamination by Cygnus internal releases. If you re-run
1676 automake and this change gets reverted, don't worry about it.
1678 1999-01-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1680 * sort.c, sort.h: New files: Implement slib's and scsh's sort

1705 * guardians.c, guardians.h (scm_make_guardian,
1706 scm_guardian_gc_init, scm_guardian_zombify, scm_guard,
1707 scm_get_one_zombie, scm_init_guardian): This is an implementation
1708 of guardians as described in R. Kent Dybvig, Carl Bruggeman, and
1709 David Eby (1993) "Guardians in a Generation-Based Garbage
1710 Collector" ACM SIGPLAN Conference on Programming Language Design
1711 and Implementation, June 1993 ftp://ftp.cs.indiana.edu
1712 /pub/scheme-repository/doc/pubs/guardians.ps.gz
1713 Author: Michael N. Livshin.

1722 1998-12-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1724 * macros.c (scm_makacro, scm_makmacro, scm_makmmacro): Added
1727 1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1729 Move the procedure slots of entities to invisible slots (so that
1730 we can have operator class objects which themselves are entities).
1731 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
1732 SCM_STRUCTF_ENTITY): New constants.
1734 * struct.c (scm_make_struct): Allocate "invisible" room for
1735 procedures if SCM_STRUCTF_ENTITY is set in vtable.
1737 * gc.c (scm_gc_mark): Mark entity procedures.

1744 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0,
1745 SCM_ENTITY_PROC_3): Adjusted for new location of procedure slots.
1747 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
1749 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
1750 of syntactic forms, similar to SCM_PROC.
1751 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
1752 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
1753 for the name symbols when needed.
1755 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
1757 * Makefile.in: Regenerated.
1759 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
1761 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
1762 take the address of _into; it might be a register. Just have
1763 scm_debug_newcell return the new cell.
1764 * gc.c (scm_debug_newcell): Just return the new cell, instead of
1765 taking the address of a place to store it as an argument.
1766 * gc.h (scm_debug_newcell): Change declaration.
1767 (Thanks to Greg Harvey.)
1769 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1779 (freecell): Use it to print freed objects, for slightly easier
1782 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1784 * backtrace.c (display_frame): Made more robust. Doesn't throw an
1785 error if no source properties can be found for a frame. (Thanks
1786 to Christian Lynbech.)
1788 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1790 * objects.h: Removed slots direct_supers and direct_slots from the
1791 definitions of the rudimentary classes described by objects.h.
1793 * objects.c, objects.h (scm_entity_p): New procedure. Together
1794 with the predicates scm_procedure_p and scm_struct_p, this
1795 predicate makes it possible to differ between structs, entities
1798 * modules.c, modules.h (scm_resolve_module): New function.
1800 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1802 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
1803 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
1806 * objects.c (scm_entity_p): New procedure.
1808 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
1809 for asubrs, rpsubrs, lsubrs and lsubr_2s.
1811 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1813 * procprop.h (scm_i_procedure_arity): Added declaration.
1815 * procprop.c (scm_i_procedure_arity): Made global; New code to
1816 handle operators and entities.
1817 (scm_procedure_property): No need to call scm_procedure_p since
1818 scm_i_procedure_arity now does all necessary type checking.
1819 Added #include "objects.h".
1821 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
1822 s_add_hook_x --> s_remove_hook_x.
1823 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
1824 Added #include "procprop.h"
1826 * feature.c, feature.h (scm_reset_hook_x): New procedure.
1827 (scm_make_hook): Optional argument defines number of arguments to
1829 (scm_make_named_hook): Take number of args as second arg.
1830 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
1831 boot-9.scm for a while); First arg is the hook. The rest are
1832 arguments passed on to the hook procedures.
1834 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
1836 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
1837 scm_logbit_p): Do the computation in ulongs. This is not as nice
1838 as doing it in bignums, but at least it's good enough for
1839 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
1841 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
1842 subexpressions. (Thanks to Charbel Jacquin.)
1844 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
1846 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
1847 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
1848 (scm_make_named_hook): New function.
1850 * feature.c: Added #include "eval.h".
1852 * modules.c (scm_make_module): Beautify the module.
1854 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1856 * modules.c, modules.h: New files: C interface to modules. (This
1857 is necessary in order to interface the object system to Guile
1858 properly. The guts of these modules will be replaced by the new
1859 module system in the future.)
1861 * init.c: Added #include "modules.h"
1862 (scm_boot_guile_1): Call scm_init_modules.
1863 (invoke_main_func): Call scm_post_boot_init_modules.
1865 * Makefile.am: Added modules.c, modules.x, modules.h.
1867 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
1869 * procs.c: #include "objects.h"
1870 (scm_procedure_p): Return #t also on structs which are operators.
1872 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
1873 <operator-metaclass> and <entity-class> to <standard-class>,
1874 <operator-class> and <entity> in order to conform with STKlos
1877 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
1878 which isn't an operator.
1879 (SCM_APPLY): Ditto, but jump to badproc.
1881 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
1883 * eval.c (SCM_CEVAL): Allow structs implanted in code.
1884 Previously, structs implanted in code were interpreted as forms
1885 the operator of which was a gloc. We solve this by checking for
1886 the zero in the emulated vcell in the struct vtable. Since
1887 implanted structs always will look like forms with a gloc
1888 operator, execution will only be slowed down by maximally one
1889 extra test-and-branch per application.
1891 * evalext.c (scm_definedp): Removed check for isyms; Added a
1892 second optional argument: It is now possible to supply an
1893 evaluation environment in which to look for the symbol.
1895 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1897 * readline.c (scm_init_readline): Set
1898 rl_basic_word_break_characters. (Thanks to Ian Grant.)
1900 * coop.c (coop_condition_variable_wait): Removed
1901 (coop_condition_variable_wait_mutex): Folded logic of
1902 coop_mutex_unlock into coop_condition_variable_wait_mutex to
1903 prevent condvar signal lossage. Previously, another thread could
1904 start to run after unlocking the mutex but before putting the
1905 current thread on the wait queue. If that thread then would
1906 signal the first, the signal would be lost. (Thanks to Christian
1909 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1911 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
1914 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1916 * objects.c (scm_i_make_class_object): Renamed from
1917 make_class_object; exported; error checking moved to
1918 scm_make_class_object and scm_make_subclass_object.
1919 (scm_make_class_object, scm_make_subclass_object): Use
1920 scm_i_make_class_object.
1921 (scm_make_subclass_object): Let the subclass have same metaclass
1924 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1926 * debug.c (scm_debug_options): Bugfix: Set the value of
1927 scm_stack_checking_enabled_p after setting debug options;
1928 #include "stackchk.h". (Thanks to Richard Polton.)
1930 1998-11-13 Radey Shouman <rshouman@metro2000.com>
1932 * unif.c (scm_array_contents): removed unnecessary test for 0
1935 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1937 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
1938 Replaced by macro `collect' in boot-9.scm.
1940 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1942 * eval.c (scm_copy_tree): Copy source properties if existent.
1944 * debug.c (scm_start_stack): Copy source when evaluating. (If we
1945 don't, we may end up passing memoized source to a transformer.)
1947 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1949 * stack.c (get_applybody): Help function which lookups the first
1950 body form of the apply closure.
1951 (read_frames): Prevent the source of the first form of the apply
1952 closure from being recorded. This would only be confusing.
1954 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
1955 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
1957 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
1959 * stacks.c (read_frame): Bugfix: Removed lingering `else'
1961 (read_frames): Use SCM_MACROEXPP.
1963 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1965 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
1966 don't contain interesting information since all arguments are
1967 present in the frame which applies the compiled closure anyway.);
1968 Skip the transformer application frames.
1970 * print.c (scm_iprin1): Print gsubrs as primitives.
1972 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1974 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
1976 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
1977 that we can identify these in a backtrace. (This change doesn't
1978 introduce any significant speed penalty.)
1980 * eval.c: Added note about `serial-map' using scm_map.
1982 * read.c, read.h (scm_read_options, scm_read_opts): Removed
1983 readline options. They should reside in their own options array.
1985 * readline.c, readline.h (scm_readline_options,
1986 scm_readline_opts): Moved readline options here.
1988 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1990 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
1991 SCM_ROCHARS instead of SCM_CHARS.
1993 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
1994 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
1996 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1998 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
1999 This is quite important since the latter clears the
2000 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
2001 every single character read...
2003 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2005 * print.c (scm_iprin1): Removed suspect looking (and indeed
2006 malevolent) semicolon after test for user supplied closure print
2007 procedure. (Thanks to Telford Tendys.)
2009 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
2010 (scm_memq, scm_memv, scm_member): Do argument checking *before*
2011 starting to search the list. Removed call to sloppy_mem_check.
2013 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
2014 procedures: Same as scm_delq_x et al, but delete maximally one
2017 * options.c (scm_options, scm_init_options): GC-protect option
2018 values of type SCM. (Thanks to Telford Tendys.)
2020 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2022 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
2023 make sure that there always is a "real" scm_lookupcar.
2025 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2027 * read.c, read.h (scm_read_opts): New read options
2028 "history-length" and "history-file".
2029 (scm_read_options): Stifle history to history length.
2031 * readline.c (scm_read_history, scm_write_history): New procedures.
2033 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2035 * eval.h (scm_macro_eval_x): Removed declaration.
2037 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
2038 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
2039 Renamed and made global.
2041 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
2042 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
2044 * evalext.c, evalext.h: New files. Contain non-R5RS things
2045 having to do with evaluation.
2047 * evalext.c (scm_serial_map): New procedure: Version of `map'
2048 which guarantees that the procedure is applied to the lists in
2050 (scm_m_sequence_to_list): New syntax: Version of `begin' which
2051 returns a list of the results of the body forms instead of the
2052 result of the last body form.
2053 (scm_definedp, scm_m_undefine): Moved from eval.c
2055 * evalext.h (scm_m_sequence_to_list): Added declaration.
2057 * macros.c, macros.h: New files.
2058 (scm_procedure_to_syntax, scm_procedure_to_macro,
2059 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
2060 scm_macro_name, scm_macro_transformer): Moved from eval.c
2061 (scm_make_synt): Moved from eval.c
2063 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
2065 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
2068 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
2070 * debug.c, print.c: Added #include "macros.h".
2072 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2074 This change adds the ability to use `unread-char' multiple times
2075 without interspersed reads and adds the new procedure
2076 `unread-string'. The change is optimized for the common case of
2077 unreading a single character. This is also the reason behind the
2078 choice to store characters in the port itself: in most cases no
2079 extra malloc is required.
2081 The amount of code in some macros in ports.h has been increased to
2082 the extent that they would fit better as C functions, but, since
2083 this code belongs to the port representation, such functions
2084 should be placed in ports.c which would cause calls back and forth
2085 between ports.c and genio.c. That is not good for performance.
2086 Also, keeping them as macros allows the compiler to do some
2087 optimizations which are needed to make the current interface
2088 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
2090 One benchmark (Guile startup time) indicates an increase of
2091 loading speed of 1%. Another (reading (using `read') boot-9.scm
2092 10 times) shows no change in performance.
2094 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
2095 made to find a beautiful solution.)
2097 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
2098 (SCM_TRY_CLRDY): New macro: Only clear the first unread
2099 character. (SCM_CLRDY clears all.)
2100 (SCM_N_READY_CHARS): New macro: Returns number of unread
2101 characters in a port. Returns wrong answer if SCM_CRDYP is false.
2102 (struct scm_port_table): New fields: `entry' contains port table
2103 index, `cp' points to last unread char, `cbuf' is the buffer for
2104 unread chars, `cbufend' points after end of the character buffer.
2106 * ports.h, ports.c (scm_unread_string): New procedure.
2107 (scm_grow_port_cbuf): New function.
2109 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
2111 (scm_generic_fgets), fports.c (local_fgets): Use a loop
2112 to read unread characters. Use SCM_TRY_CLRDY instead of
2115 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
2117 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
2119 * genio.c, genio.h (scm_ungets): New function.
2121 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
2124 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2126 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
2127 declarations. (Thanks to Russ McManus.)
2129 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2131 * numbers.c (num2long): As a software archeologist, I'm proud of
2132 this finding! :) Preliminary dating suggests an almost 4 year old
2133 remnant from the SCM ancestor. The sample has been removed from
2134 the finding site and is now safely stored in the repository.
2136 * numbers.h: Removed prototype for num2long.
2138 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
2140 * gh_data.c (gh_scm2doubles): Make it possible to pass result
2141 array as second arg.
2142 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
2143 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
2144 * gh.h: Updated and added prototypes.
2146 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
2148 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
2150 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
2152 * guile-snarf.in: Never generate an empty file. (Thanks to
2155 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
2156 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
2157 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
2158 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
2159 gh_new_procedure5_0): Specify argument types, to appease C++
2160 compilers. (Thanks to Brad Bowman.)
2162 Bug reports from Russ McManus:
2163 * guile-snarf.in: If the CPP environment variable is set, use that
2164 as the C preprocessor, instead of the preprocessor autoconf
2166 * snarf.h (SCM_PROC): Cast the function pointer passed to
2167 scm_make_gsubr, to satisfy C++.
2169 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2170 Use the handler passed, instead of ignoring it and using
2171 gh_standard_handler. (Thanks to Etienne Bernard.)
2173 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
2175 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
2178 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>

2195 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
2198 * script.c (scm_compile_shell_switches): Define
2199 use-emacs-interface in the root module, so the repl code can see
2200 it. See today's change to top-repl in ice-9/boot-9.scm.
2202 * filesys.c (set_element, get_element): Make sure that `element'
2203 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2204 Boekemeier and Jorgen "forcer" Schaefer.)
2206 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2208 * chars.c (scm_charnames): In ASCII character name table, make
2209 newlines print as #\newline by default, not #\nl.
2211 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2212 alphabetical order. Oh thrills. But it helps me know how far
2213 along in the compilation I am.
2214 * Makefile.in: Regenerated.
2216 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2218 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2219 #bytes(...) to #y(...), and syntax for short vectors from
2220 #short(...) to #h(...). This may seem nutty, but, like the other
2221 uniform vectors, byte vectors and short vectors want to have the
2222 same print and read syntax (and, more basic, want to have read
2223 syntax!). Changing the read syntax to use multiple characters
2224 after the hash sign breaks with the conventions used in R5RS and
2225 the conventions used for the other uniform vectors. It also
2226 introduces complexity in the current reader, both on the C and
2227 Scheme levels. (The Right solution is probably to change the
2228 syntax and prototypes for uniform vectors entirely.)
2230 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
2232 Don't use local_fgets on sockets; ftell doesn't work on sockets.
2233 (Thanks to Jorgen "forcer" Schaefer.)
2234 * ports.h (SCM_NOFTELL): New flag.
2235 * fports.c (local_fgets): If it's set, use the generic fgets.
2236 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
2238 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2240 * script.c (scm_compile_shell_switches): Add handling of -q switch
2241 (inhibit loading of user init file).
2242 (scm_shell_usage): Add usage text for -q switch.
2243 (scm_compile_shell_switches): Always load user init file first if
2244 it is loaded at all.
2246 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
2248 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
2249 and is now broken under NetBSD. I can't fathom what it's trying
2250 to do, so I've replaced it with something that I do understand,
2251 which seems to work, and which isn't broken on NetBSD. "Progress?
2252 You Decide." (Thanks to Perry Metzger.)
2254 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
2255 signed/unsigned comparison.
2257 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
2259 Warning fixes from Greg Harvey:
2260 * unif.c (scm_array_set_x): initializer for pos
2261 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
2262 * struct.c (scm_struct_ref, scm_struct_set_x): Added
2263 initializers for field_type, since EGCS so desparately wants to
2265 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
2266 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
2267 when GUILE_DEBUG is defined.
2268 * dynwind.h (scm_wind_chain): Same.
2269 * ports.h (scm_pt_size, scm_pt_member): Same.
2270 * print.h (scm_current_pstate): Same.
2271 * procs.h (scm_make_cclo): Same.
2273 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
2275 Handle short and long long uniform arrays properly. (Thanks to
2277 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
2278 raeql_1): Add cases for scm_tc7_svect (short vectors) and
2279 scm_tc7_llvect (long long vectors).
2281 Change the way libguile and boot-9.scm are timestamped, to try to
2282 get rid of these spurious mismatch warnings. Now both
2283 libguile/versiondat.h and ice-9/version.scm are generated directly
2284 by the configuration process, rather than having version.scm
2285 generated directly, and libguile/versiondat.h generated by the
2286 Makefile, which is generated by configure. It seems that
2287 sometimes the Makefile would change, but versiondat.h depends on
2288 Makefile.in, not Makefile, so it wouldn't get rebuilt.
2289 * Makefile.am (versiondat.h): Target removed; this is generated
2290 directly by the configure script now.
2291 (BUILT_SOURCES): Remove versiondat.h.
2292 * versiondat.h.in: New file, transformed by the configure script
2294 * Makefile.in: Regenerated.
2296 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
2297 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
2298 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
2299 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2300 if we want to use them in a header file some day, we can. (Thanks
2301 to Michael Livshin.)
2303 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2304 SCM numbers, so we won't have rollover problems; the range of a
2305 signed long in milliseconds is about 25 days. (Thanks to Karl
2308 Don't redefine sleep and usleep; fix this problem now.
2309 * coop.c (sleep, usleep): Remove declarations; we don't use or
2310 redefine these any more.
2311 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2312 job of usleep and sleep in a thread-friendly way. We can use
2313 these in the rest of Guile. Define versions for systems both with
2314 and without iselect.
2315 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2316 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2317 we're just using it, not redefining it, we can use a K&R style
2319 (sleep): Declare this, too, if the system hasn't.
2320 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2321 scm_uthread_sleep if they're available; otherwise, just call the
2323 * scmconfig.h.in: Regenerated.
2325 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2327 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2329 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2331 * threads.c: Doc fix.
2333 The argument type of usleep varies from system to system,
2334 as does the return type. We really shouldn't be redefining usleep
2335 at all, but I don't have time to clean that up before the 1.3.
2336 release. It's on the schedule for afterwards. (Thanks to Julian
2338 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2340 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2341 * scmconfig.h: Regenerated.
2343 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2344 right way to handle system variation. Autoconf's approach is the
2346 * simpos.h (scm_software_type): Declaration deleted.
2348 * script.c (scm_find_executable): Don't test if unix is #defined
2349 here; first, NetBSD doesn't #define it, and second, it's the wrong
2350 way to go about these things. (Thanks to Perry Metzger.)
2351 (dld_find_executable): Delete this MSDOS support code. This isn't
2352 the way we want to support this; it needs to be rethunk at a
2355 * genio.c (scm_do_read_line): Don't just politely check that the
2356 line was either non-empty or EOF. Abort if it's empty and not
2359 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2361 * scmconfig.h.in: Regenerated.
2363 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2366 * genio.c (scm_do_read_line): Count lines correctly when the file
2367 doesn't end in a newline.
2369 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
2371 * genio.c (scm_do_read_line): Maintain the line count correctly.
2372 (Thanks to Harvey J. Stein and Greg Harvey.)
2374 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
2377 * numbers.c (big2str): Protect t from garbage collection until
2378 we're done. (Thanks to Gary Houston.)
2380 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
2382 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
2384 * Makefile.in: Regenerated.
2386 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
2387 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
2390 Do magic to mix reads and writes on stdio FILE-based ports.
2391 (Thanks to Christian Lynbech.)
2392 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
2394 (pre_read, pre_write): New functions.
2395 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
2396 local_fputs): Call them.
2397 (local_fflush): Mark the port as ready for reading and writing.
2398 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
2399 flags on new port objects. This might not be accurate --- who
2400 knows what state the FILE * is in when we get it --- but it won't
2401 do extraneous calls to fflush or fseek, so it's no worse than the
2402 behavior before this change.
2403 * ports.h: Add comment.
2405 Centralize the creation of port objects based on stdio FILE * in
2406 fports.c; don't just throw them together anywhere.
2407 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
2408 what the rest of Guile wants. Don't set the revealed count;
2409 that's only appropriate for stdin, stdout, stderr.
2410 (scm_standard_stream_to_port): This function does set the revealed
2412 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
2413 not scm_stdio_to_port.
2414 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
2415 * fports.c (scm_open_file): Same.
2416 * posix.c (scm_pipe): Same.
2417 * socket.c (scm_sock_fd_to_port): Same.
2418 * ioext.c (scm_fdopen): Same.
2419 (scm_freopen): Moved from here to...
2420 * fports.c (scm_freopen): ... here. This is really something that
2421 munges the internals of an fport, so it should go here.
2422 * fports.h (scm_stdio_to_port): Adjust prototype.
2423 (scm_standard_stream_to_port, scm_freopen): New protoypes.
2424 * ioext.h (scm_freopen): Prototype removed.
2426 * filesys.c (set_element, get_element): This can work on both pipe
2427 and file ports, so use SCM_FPORTP to typecheck, instead of testing
2430 * scmconfig.h.in: Regenerated.
2432 Change the definition of the functions in scm_ptobfuns so that
2433 they get passed the port object, not the port's stream.
2434 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
2435 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
2436 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
2437 Pass the port itself to the scm_ptobs function.
2438 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
2439 scm_generic_fgets): Same.
2440 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
2441 getc_void_port, fgets_void_port, close_void_port): Just change the
2442 argument names; these functions don't really do anything.
2443 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
2444 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
2445 port as an argument, and use SCM_STREAM to get the stdio FILE *.
2446 Also, use prototyped definitions, and get rid of the extra
2448 (scm_fptob, scm_pipob): We don't need casts here any more.
2449 * strports.c (prinstpt): Use prototype declarations.
2450 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
2451 and use SCM_STREAM to get the string info. Also, use prototyped
2452 definitions, and get rid of the extra declarations.
2453 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
2456 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
2457 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
2459 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
2460 scm_fgets, for consistency.
2461 (scm_fptop, scm_pipob): References updated.
2463 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
2465 Include the source location in error messages for scripts.
2466 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
2467 stack is still there when we catch the error.
2468 * throw.c (handler_message): If we are handling an error with a
2469 message, then put together the proper arguments and call
2470 scm_display_error, instead of scm_display_error_message. That
2471 displays source location, if it can find it.
2473 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
2475 * gc.c (scm_unprotect_object): Change this so that calls to
2476 scm_protect_object and scm_unprotect_object nest properly.
2477 (scm_protect_object): Doc fixes.
2479 * strings.c (scm_string_set_x): Require the argument to be a
2480 writable string, not a substring or a symbol.
2481 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
2482 (Thanks to John Redford and Charbel Jacquin.)
2484 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
2486 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
2488 * eval.c (safe_setjmp): Remove this misunderstanding.
2489 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
2492 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
2494 * libguile.h: Mark these as C declarations, for compilation by C++
2497 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
2498 __cplusplus clause. I seriously doubt this ever worked the way
2499 the author seems to have intended.
2501 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
2503 Utterly needless cleanups to hopelessly messy code.
2504 * ports.c: Doc fixes.
2505 (scm_fflush): Moved to ...
2506 * genio.c (scm_fflush): ... here, amongst all the other port
2507 method invocation functions.
2508 * genio.h, ports.h: The prototype moves too.
2510 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
2512 * backtrace.c (display_error_body): The current frame does not
2513 always have a parent frame; consider a function called directly
2514 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
2517 * alloca.c (alloca): Undo yesterday's changes, and simply call
2518 malloc directly for storage, and abort if we don't get what we
2519 want. The situation is much simpler --- just call malloc. Emacs
2520 has bizarre/evil requirements (signal handlers might malloc unless
2521 you set this global flag, so you have to set the flag around all
2522 calls to malloc) which we are certainly not going to conform to,
2523 so we can do the simple and obvious thing.
2525 * coop.c (coop_condition_variable_wait): Make this function
2526 static. It's only useful internally --- you should never just
2527 wait on a condition variable.
2528 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
2530 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2532 * unif.c (scm_array_set_x): Accept any kind of number as an
2533 element for a uniform vector of doubles. This is more consistent
2534 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
2536 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
2537 works; I can't conveniently test it myself. (Thanks to Dvid
2538 Tillman for the bug report.)
2540 * init.c: Doc fixes.
2542 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
2543 from here, not from scm_compile_shell_switches (which is a pretty
2544 dumb place to do it).
2545 (scm_load_startup_files): New function.
2546 (scm_ice_9_already_loaded): Variable moved to here from script.c.
2547 * script.c (scm_compile_shell_switches): Don't load the startup
2549 (scm_ice_9_already_loaded): Variable moved.
2550 * init.c (scm_load_startup_files): Prototype for new function.
2551 * gh_init.c (gh_enter): Doc fix.
2553 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2555 Some anti-warning changes from Greg Harvey.
2556 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
2557 warnings when it doesn't understand our NORETURN declarations in
2559 * posix.c (scm_mknod): Similar.
2561 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2563 * posix.c (scm_getpwuid): If we can't find an entry, return our
2564 own message, instead of using scm_syserror --- the getpwMUMBLE
2565 functions don't set `errno' to anything interesting.
2567 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2569 Get rid of warnings from the cooperative threading system.
2570 * threads.h (scm_single_thread_p, scm_yield,
2571 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
2572 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
2573 scm_wait_condition_variable, scm_signal_condition_variable): Add
2574 prototypes for these Scheme-visible functions.
2575 * coop-defs.h (coop_next_runnable_thread,
2576 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
2577 Prototypes for these here, even though they're from iselect.c.
2578 (coop_condition_variable_wait, coop_join): Add prototypes.
2579 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
2580 scm_threads_free_condvar): Make these smob functions static.
2581 * coop-threads.h (coop_init): Give this a real prototype.
2582 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
2583 (coop_next_runnable_thread): No need to provide prototype; it's in
2586 * scmconfig.h.in: .detarenegeR
2588 * iselect.c, threads.c: Doc fixes.
2590 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2592 * Makefile.in: Regenerated with a patched automake, to get
2593 dependency generation right when using EGCS.
2595 * inet_aton.c (inet_aton): Add prototype, to remove compiler
2596 warning. (Thanks to Robert Pluim.)
2598 * inet_aton.c (inet_aton): Reassure the compiler that the
2599 arguments to the <ctype.h> macros are all unsigned characters, not
2602 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2604 Getting rid of more warnings...
2605 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
2606 today's change to ../configure.in.
2607 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
2608 * scmconfig.h.in: Regenertaded.de.,.__
2609 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
2610 (scm_localtime, scm_mktime): Use a const char * to manipulate the
2613 * readline.c: Doc fix.
2614 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
2615 * readline.h (scm_filename_completion_function): Add prototype.
2616 (scm_init_readline): Make this into a prototype.
2618 * readline.c (scm_filename_completion_function): Use SCM_PROC to
2619 declare this, instead of calling scm_make_subr manually.
2621 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
2623 * readline.h (scm_init_readline): Add prototype for this.
2624 (scm_init_readline): Make this a real prototype.
2626 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
2628 Warning fixes from Maciej Stachowiak:
2629 * backtrace.h (scm_display_application, scm_backtrace): Add
2631 * debug.c (scm_m_start_stack): Make this function static.
2632 * fluids.h (scm_fluid_p): Add prototype.
2633 * procprop.c (scm_i_procedure_arity): Make this function static.
2634 * regex-posix.c (scm_regexp_error_msg): Make this function static.
2635 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
2636 * root.h (scm_dynamic_root): Add external prototype.
2637 * scmsigs.h (scm_usleep): Add external prototype.
2638 * script.h (scm_init_script): Use prototype, not K&R decl.
2639 * stacks.h (scm_stack_id): Add external prototype.
2640 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
2642 1998-09-30 Mark Galassi <rosalia@cygnus.com>
2644 * gh.h: took out the definitions of vset and vref, since they are
2645 replaced by the proper vector routines that correspond to the R4RS
2648 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
2650 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
2651 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
2652 third argument, a C expression that should result in a SCM value,
2653 which is used to initialize the variable. Reimplemented
2654 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
2657 * version.h (scm_libguile_config_stamp): Add prototype.
2658 (From Maciej Stachowiak.)
2660 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
2662 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
2663 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
2665 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
2667 * print.c (scm_iprin1): Rather than having one i, and using it in
2668 several places, declare a fresh i local to each block where it is
2669 used, and give it a signedness appropriate to its use in each case.
2670 (scm_iprlist): Same.
2672 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
2673 comparison warnings.
2675 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
2676 signed/unsigned clashes.
2678 * posix.h (scm_tmpnam): Added prototype.
2680 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
2681 scm_make_subclass_object): Add external prototypes.
2683 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
2684 comparison is okay here.
2686 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
2688 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
2689 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
2691 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
2694 * load.c (swap_port): Make this function static.
2696 * load.c (scm_search_path): Make max_path_len and max_ext_len
2697 unsigned, since they're compared against string sizes.
2699 * load.c (init_build_info): Make i unsigned.
2701 * ioext.h (scm_read_line): Add prototype.
2703 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
2704 scm_hash_fn_remove_x): Make hash bucket index local variable k
2705 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
2706 accurately as possible.
2708 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
2709 comparisons, and range checking to make sure those casts are
2712 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
2713 signed/unsigned comparisons.
2715 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
2716 avoid signed/unsigned comparisons.
2717 * smob.h (scm_numsmob): Change extern declaration to match.
2719 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
2720 avoid signed/unsigned comparisons.
2721 * ports.h (scm_numptob): Change extern declaration to match.
2722 (scm_current_load_port, scm_set_port_line_x,
2723 scm_set_port_column_x): New prototypes.
2725 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
2726 test code, and it causes warnings.
2728 * gh.h (gh_int2scmb, gh_uniform_vector_length,
2729 gh_uniform_vector_ref): Added prototypes.
2731 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
2732 debugging support unconditionally. That's backtrace.c, stack.c,
2733 debug.c, and srcprop.c.
2734 (EXTRA_libguile_la_SOURCES): Omit those from here.
2735 * Makefile.in: Regenerated.
2737 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2739 * options.c (scm_options): Bugfix: Allow empty list of options!
2741 * debug.c, debug.h (scm_single_step): Removed.
2742 (scm_with_traps): New procedure. This procedure could easily be
2743 written in Scheme but needs to be highly optimized.
2745 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
2747 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
2748 Check SCM_TRAPS_P before trapping.
2750 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
2752 Changes to avoid signed/unsigned comparison warnings.
2753 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
2754 (scm_gc_sweep): Make n and j local to the blocks they're used in,
2755 so they can have appropriate types for each application. Make i
2756 signed. Use initializers in some spots. I'll probably pay for
2758 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
2759 (scm_must_realloc): Make nm unsigned.
2760 (init_heap_seg): Make new_seg_index and n_new_objects signed.
2761 (scm_init_storage): Use prototype-style definition, and make the
2763 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
2764 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
2766 * filesys.c (scm_readlink): Make local vars rv and size ints, to
2767 avoid signed/unsigned comparison warnings, and because the return
2768 value of readlink may be -1. Don't bother casting the third
2769 argument to readlink.
2771 * filesys.c (scm_dirname, scm_basename): Move these to their own
2772 page, at the end of the file.
2773 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
2775 * eval.h (scm_eval_options_interface): Add external prototype for this.
2776 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
2778 * eval.c (scm_lookupcar1): Make this static.
2780 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
2781 Make these prototype declarations, not K&R-style.
2783 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
2784 unsigned comparison warning.
2786 * appinit.c: File removed. It had a single function in it, empty,
2787 whose reason for existence is explained in no documentation or
2788 comment. I think it's there as a default for some Tcl-style
2789 initialization, but Tcl abandoned that approach a while ago.
2790 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
2791 (BUILT_SOURCES): Remove appinit.x.
2792 * Makefile.in: Regenerated.
2794 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
2796 * Makefile.in: Regenerated using the last public version of
2797 automake, not the hacked Cygnus version.
2799 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
2801 Remove Totoro kludge.
2802 * Makefile.in, scmconfig.h.in: Regenerated.
2803 * init.c, readline.c: Don't check if TOTORO is #defined.
2805 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
2807 * Makefile.am: Adjust for new thread configuration system.
2808 (INCLUDES): Include the value of THREAD_CPPFLAGS.
2809 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
2811 (THREAD_LIBS): Definition deleted; automake will generate such
2812 things automatically.
2813 * Makefile.in: Regenerated.
2815 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
2817 Simplify smob and port marking; set the mark bit in the generic
2818 marking code, and make marker routines only responsible for
2819 turning up outgoing pointers.
2820 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
2821 before calling the marking function. Don't call the marking
2822 function if it's zero.
2823 * markers.c (scm_mark0): Just return #f. This function isn't
2824 necessary at all now, but it's harmless to call it. We'll leave
2825 it in so other folks' code doesn't croak at link time.
2826 (scm_markcdr): Don't call SCM_SETGC8MARK.
2827 * async.c (mark_async): Don't call SCM_SETGC8MARK.
2828 * dynl.c (mark_dynl_obj): Same.
2829 * root.c (mark_root): Same.
2830 * srcprop.c (marksrcprops): Same.
2831 * unif.c (markra): Same.
2832 * variable.c (scm_markvar): Same.
2833 * ports.c (scm_markstream): Same.
2834 (void_port_ptob): Specify zero for our marking function.
2835 * debug.c (debugobjsmob): Same.
2836 * dynwind.c (guardsmob): Same.
2837 * filesys.c (dir_smob): Same.
2838 * fluids.c (fluid_smob): Same.
2839 * fports.c (scm_fptob, scm_pipob): Same.
2840 * mallocs.c (mallocsmob): Same.
2841 * regex-posix.c (regex_t_smob): Same.
2842 * smob.c (freecell, flob, bigob): Same.
2843 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
2844 * throw.c (jbsmob, lazy_catch_funs): Same.
2846 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2848 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
2849 scm_copy_tree on code in order not to let memoized code to leak
2850 out. Thus, scm_copy_tree needs to copy vectors as well since
2851 quasiquote can introduce evaluated code also inside vector
2854 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2856 * eval.c (scm_copy_tree): Removed ability to copy vectors.
2858 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
2859 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
2862 * unif.c: Say that ivect and uvect are of type signed and unsigned
2863 long instead of int in commentary so that it correctly describes
2866 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2868 * stime.c: Removed declaration of strptime. (It should be
2869 declared by the system headers. If it turns out that some systems
2870 don't, we'll handle that then.) (Thanks to Greg Troxel.)
2872 * stime.h: Renamed TIMEH --> STIMEH
2874 * backtrace.c (scm_display_error, scm_display_backtrace): In order
2875 to increase portability, don't use structure assignment.
2876 (Thanks to Nicolas Neuss.)
2878 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
2880 (finalize_fd_sets): Added empty statement after last case label.
2881 (Thanks to Nicolas Neuss.)
2883 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
2886 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
2888 * init.c, readline.c: OK, I won't have these readline.x bug
2889 reports anymore. We've had them since April. The current reason
2890 is a completely unintelligible failure of totoro.red-bean.com to
2891 do the test for rl_getc_function in libreadline correctly. This
2892 kludge overrides the test if we're on totoro so that the snapshot
2893 generation process can work.
2895 * readline.c: Define a strdup replacement if not existent on system.
2897 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2899 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
2900 This change makes scm_make_vector R5RS compatible. We cannot keep
2901 the third argument since people want to be able to deduce the form
2902 of the C function call only by looking at R5RS. (At the same time
2903 we have removed some unnecessary complexity!)
2905 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
2906 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
2907 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
2908 argument in call to scm_make_vector.
2910 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2912 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
2913 This macro is useful in applications.
2915 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2917 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
2918 (scm_parse_path, scm_search_path): New Scheme level procedures.
2920 * load.h (scm_internal_parse_path, scm_parse_path,
2921 scm_search_path): Declared.
2923 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2925 * filesys.c (dirname, basename): New procedures.
2927 * init.c (scm_boot_guile_1): Removed condition around
2930 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
2931 new data type (guards) for representation of C level guards and
2932 data on the wind chain.
2933 (scm_internal_dynamic_wind): New function.
2935 * dynwind.h: Declare scm_internal_dynamic_wind.
2937 * root.h (scm_root_state): Added scm_cur_loadp.
2939 * root.c (mark_root): Added comment about cur_loadp.
2941 * load.c: #include "dynwind.h";
2942 (scm_primitive_load): Use scm_inner_dynamic_wind to update
2945 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
2947 * ports.c (current-load-port): New procedure.
2949 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2951 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
2952 not a tty, return #f.
2954 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
2955 to Julian Satchell and Roland Kaufmann.)
2957 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
2958 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
2960 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2962 * debug.h, debug.c (scm_start_stack): New function. Implements
2963 the guts of old scm_m_start_stack.
2965 * debug.c (scm_m_start_stack): Use scm_start_stack.
2967 * init.c (scm_start_stack, scm_restart_stack): Renamed to
2968 start_stack and restart_stack. (These have static scope.)
2970 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2972 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
2973 readline functions to come in release 2.3. (Thanks to Chet
2975 (handle_errors): Use the above functions.
2977 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2979 * readline.c: Improvements for readline support: Handle errors
2980 better; Implement before-read-hook.
2982 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2984 * init.c (scm_boot_guile_1), readline.c: Test for
2985 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
2986 assure that we have version >= 2.1.)
2988 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
2990 * readline.c (scm_readline): Defer interrupts while we're calling
2993 * readline.c (scm_add_history): Bugfix: Do strdup before giving
2994 away the string to add_history.
2995 (completion_function): Do completion for readline. (Thanks to
2997 (scm_filename_completion_function): New procedure: Filename
2999 (current_input_getc): New function. Use this one instead of
3000 standard getc from readline.
3002 * throw.c, throw.h (scm_handle_by_throw): New function: This
3003 handler throws errors to next handler on the dynwind chain.
3005 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
3007 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
3010 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3012 * procprop.c (scm_i_procedure_arity): New function. Returns arity
3014 (scm_procedure_properties): Modified to return arity together with
3016 (scm_procedure_property): Added the read-only property `arity'.
3017 (scm_set_procedure_property_x): It is an error to set the `arity'
3020 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
3021 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
3023 * procprop.h (scm_sym_arity): New symbol.
3025 * objects.c (scm_set_object_procedure_x): New procedure: Use this
3026 to set the dispatch procedure of an operator or entity object.
3028 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
3029 Made procedure slots read-only.
3031 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
3032 scm_tcs_cons_gloc case in zero args switch; Fixed args
3033 construction for operators in scm_tcs_cons_gloc case in two args
3036 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3038 * fluids.c: Removed use of assert.h (in order to avoid
3041 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
3043 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
3045 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
3046 change makes the evaluator safer at the cost of evaluation speed.
3047 It handles the case when the user has added a non-immediate
3048 improper end of the application form, e.g., `(+ 0 . x)'.
3049 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
3050 minimize the extra cost as much as possible. The new code is
3051 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
3052 problem with structs planted directly in the code (e.g. by a
3053 macro). This no longer causes segmentation fault. (Thanks to
3056 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
3057 arg `proc' in order to be able to throw errors; New argument
3060 * Removed extra #include "debug.h"
3062 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
3064 * scmsigs.c: Declare usleep as returning void on some systems.
3065 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
3068 * coop.c (usleep): Return void on some systems.
3070 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3072 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
3074 * coop.c: Changed return type of usleep to int.
3076 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
3077 isn't found in the OS.
3079 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
3080 isn't enabled. (Thought that I had made this change ages ago...)
3082 * iselect.c: Declare bzero if not defined by OS.
3084 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3086 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
3087 condition. (Thanks to John Tobey.)
3089 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
3090 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
3093 * __scm.h: Start the long-term project of moving to POSIX threads.
3094 Phase 1: Classification of all critical sections.
3095 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
3096 for A sections. (See comments in __scm.h for details.)
3098 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
3099 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
3101 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3103 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
3104 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
3105 (libpath.h, versiondat.h): Replaced dependency on Makefile with
3106 dependencies on $(srcdir)/Makefile.in
3107 $(top_builddir)/config.status in order to avoid circularity.
3109 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
3110 from argc if argc was 0 initially.
3112 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
3113 in generation of libpath.h.
3115 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
3117 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
3118 libguile from 2 to 3.
3120 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
3122 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
3124 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
3126 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
3127 scm_set_port_column_x, scm_port_filename,
3128 scm_set_port_filename_x): Removed optional arguments. Added
3129 proper argument checking.
3131 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
3132 stack size in machine words.
3134 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
3135 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
3136 to Ole Myren Röhne.)
3138 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
3140 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
3141 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
3143 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
3146 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
3147 procedure apply: Copy argument lists before pushing them unto the
3148 environment so that the environment won't get mutated due to
3149 manipulation of procedure arguments. This should perhaps be
3150 regarded as a temporary solution until someone finds a more
3151 efficient one. (Thanks to Maciej Stachowiak.)
3153 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
3155 * script.c (scm_compile_shell_switches): Use "guile" as default
3156 zero arg if argc is NULL.
3158 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
3160 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
3161 is zero. (Thanks to Dirk Herrmann.)
3163 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
3165 * ports.c (scm_add_to_port_table): First line is now line 0
3166 (was 1). (Interface changed according to suggestion by Per
3169 * backtrace.c (display_header): Add 1 to line and column numbers
3170 when presenting them to the user.
3172 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3173 from debug.c --> eval.c
3175 * eval.h, eval.c (scm_eval_options_interface): New options
3177 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3178 i.e. stacks for new threads.
3180 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3182 * eval.c (unsafe_setjmp): Removed with #if 0.
3184 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3187 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3188 to avoid compiler warnings.
3190 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3192 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3194 * throw.c (handler_message): Print message on current error port
3195 instead of default error port. (Thanks to Maciej Stachowiak.)
3197 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3199 * ports.c (scm_add_to_port_table): allocate in units of
3200 struct scm_port_table *, not struct scm_port_table.
3201 * posix.c (scm_close_pipe): remove the port from the port table
3203 Thanks to Rob Engle for both fixes.
3205 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3207 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3208 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3210 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3212 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3214 * backtrace.c (display_error_body, display_backtrace_body),
3215 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
3216 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
3217 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3218 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
3221 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
3222 don't receive the jmpbuf arg anylonger.
3223 (scm_catch): Don't accept a #f tag.
3224 (scm_throw): Check that key is a symbol.
3225 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
3227 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
3229 * async.c (async_pending): Removed declaration.
3231 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3233 * dynwind.c (scm_wind_chain): New debug function.
3235 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
3236 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
3237 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
3238 extra layer of functions around the body and handler of a thread.
3239 This extra layer makes sure that the handler is called in the
3240 dynamic context of the surround (= empty dynwind list), but under
3241 the *dynamic root* of the body. We can not use the dynamic root
3242 of the surround since that root belongs to another thread => stack
3243 is not handled correctly. It may seem ugly to use this extra
3244 layer, but the extra cost in terms of execution time is really
3245 negligible compared to the total amount of time required to create
3246 a thread, and it would reduce maintainability to duplicate the
3247 crucial and complicated steps performed by cwdr.
3249 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
3250 (SCM_ALLOW_INTS): Added thread switching code before interrupts
3251 get re-enabled. The important effect of this is that interrupts
3252 are blocked during thread switching so that thread data structures
3253 don't risk getting messed up by an unfortunate signal.
3254 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
3255 seems to do more aggressive optimization which actually move
3256 instructions around in these macros in a fatal way. Therefore:
3257 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
3258 just superstitious...)
3259 (SCM_TICK): Maybe do a context switch and take care of asyncs.
3260 This macro should be used instead of SCM_ASYNC_TICK since the
3261 latter doesn't do context switches any more.
3263 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
3264 instead of SCM_ASYNC_TICK.
3266 * coop.c, iselect.c: Since thread switches are now performed with
3267 interrupts masked, we can't use the old mechanism of delivering
3268 signals immediately when they arrive. Signals must instead be
3269 delivered when the asyncs run *after* the end of the critical
3270 section in scm_internal_select. But this also means after context
3271 switch so that the signal will be delivered to a different thread.
3272 To avoid this, I have changed the protocol of
3273 coop_wait_for_runnable_thread and friends so that they are allowed
3274 to return the original thread. So, if a signal arrives during
3275 scm_internal_select, we won't any longer be forced do a context
3276 switch, but can remain in the same thread and deliver the signal
3279 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
3280 scm_asyncs_pending and made it global.
3282 * iselect.c: Small fixes.
3284 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
3285 coop_condition_variable_init, coop_condition_variable_wait,
3286 coop_condition_variable_signal): Changed return type from `void'
3287 to `int'. This is to adhere closer to the pthreads interface.
3288 This, in turn, is part of an attempt to provide C versions of the
3289 mutex and condition variable primitives which can be part of a
3290 frontend to COOP or pthreads.
3292 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
3293 coop_condition_variable_destroy): New functions.
3295 * coop-threads.c (scm_wait_condition_variable): Use
3296 coop_condition_variable_wait_mutex.
3298 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
3299 Definitions moved to coop-defs.h.
3301 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3302 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3303 scm_cond_destroy): New C interface to mutecis and cond vars.
3305 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3307 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3309 * iselect.c: Now several threads can wait on the same file
3310 descriptor. The behaviour is compatible with OS select: All
3311 threads waiting for the fd return with the same status.
3313 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3315 * coop-threads.c, threads.h (scm_spawn_thread): New function.
3316 Can spawn a thread from application C code.
3318 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3320 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3321 gh_doubles2scm): New functions.
3323 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3325 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3326 commented-out version of gh_eval_str()
3328 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3330 * socket.c (scm_bind): free soka after use.
3332 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3334 * stime.c (tzvar): new variable.
3335 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3336 avoid memory leaks when allocating.
3338 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3340 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3343 * gc.c, tags.h: Doc fixes.
3345 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3347 * eval.c (macro-eval!): Removed. This function was a design bug.
3348 It allowed memoized code to leak out to the scheme level. Most
3349 things that you could do with `macro-eval!' can be done with
3352 1997-12-20 Tim Pierce <twp@skepsis.com>
3354 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3355 scm_fgets now depends on ftell(3) to know how many bytes were
3358 1997-12-15 Tim Pierce <twp@skepsis.com>
3360 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3361 dealing with strings.
3363 1997-12-13 Tim Pierce <twp@skepsis.com>
3365 Make %read-line more suitable for implementing read-line efficiently.
3366 * ioext.c (scm_read_line): Strip the terminating newline from a
3367 string, and return a cons of the string and its terminator.
3369 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
3370 of the string that is read is stored in this memory location.
3371 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
3372 * genio.c, genio.h (scm_do_read_line): Update caller.
3373 * ports.h (scm_ptobfuns): Update typedef.
3374 * fports.c (scm_fptob, scm_pipob): Update struct.
3376 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3378 * filesys.c (set_element): Return file descriptor.
3379 (fill_select_type): Return the highest file descriptor.
3380 (scm_select): Tell select about the highest file descriptor. On
3381 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
3382 Therefore the extra overhead for calculating the maximum fd seems
3383 to be more than compensated. Is this correct? In any case,
3384 scm_internal_select will be much faster with this info.
3385 (scm_select, fill_select_type, set_element): Don't accept any kind
3386 of object in the file descriptor list or vector.
3388 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3390 * iselect.c (finalize_fd_sets): Bugfix.
3392 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3394 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
3395 when using scm_internal_select (since we might switch to another
3398 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3400 * simpos.c (scm_system): always define: use sysmissing if not
3401 available. Check for HAVE_SYSTEM instead of _Windows (does
3402 Windows lack system or does it have an unusable one?).
3403 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
3404 Let the argument be optional: if not supplied, call system(NULL).
3406 * ports.c (scm_close_port): relax the type check from OPPORTP to
3407 PORTP; closing a closed port is allowed.
3409 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
3411 * fports.c (scm_fgets): Return if the last char in a chunk is
3412 newline. When fgets returns a string whose length is `size-1', it
3413 is ambiguous whether a whole line was retrieved, so we must check
3414 explicitly whether a line terminator is present.
3416 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3418 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
3419 before taking the CDR. (Thanks to Harald Meland.)
3421 * filesys.c (scm_stat): Slightly optimized.
3423 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
3425 * ports.c (scm_close_port): Make sure the port is open before
3428 * guile-snarf.in: Pass args through to gcc in a way that preserves
3429 whitespace boundaries. (Thanks to Greg Badros.)
3431 1997-12-02 Tim Pierce <twp@skepsis.com>
3433 * stacks.c (scm_frame_procedure): Reverse the logic in the return
3434 statement. (Thanks to Doug Evans for pointing this out.)
3436 1997-12-01 Tim Pierce <twp@skepsis.com>
3438 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
3440 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
3442 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
3443 errno macro expansion of this field name. (errno is a C
3444 preprocessor macro on some systems.)
3446 1997-11-29 Tim Pierce <twp@skepsis.com>
3448 * iselect.c: Doc fix.
3450 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
3452 * init.c (scm_start_stack): Removed initialization of
3453 scm_the_last_stack_var.
3455 * backtrace.h: Declare scm_the_last_stack_var.
3457 * backtrace.c: Define scm_the_last_stack_var.
3459 * root.c (mark_root): Don't mark the_last_stack_var.
3461 * root.h (scm_root_state): Removed the_last_stack_var.
3463 * throw.c: Added #include "fluids.h"
3464 (ss_handler): `the-last-stack' is now a fluid.
3466 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
3467 --> the_last_stack_fluid.
3469 * backtrace.c: Added #include "fluids.h"
3470 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
3471 (scm_backtrace): `the-last-stack' is now a fluid.
3473 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
3474 after scm_init_fluids.
3476 1997-11-28 Tim Pierce <twp@skepsis.com>
3478 * iselect.c: #ifdef USE_THREADS around thread-related includes.
3480 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
3481 DLSYM_ADDS_USCORE to decide whether to add an underscore.
3483 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3485 * iselect.c (coop_next_runnable_thread,
3486 coop_wait_for_runnable_thread): Disable interrupts so that no
3487 async is executed before a potential error_revive.
3488 (scm_internal_select): Disable interrupts during the parts of the
3489 code which manipulate the sleep queue and the file descriptors.
3491 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3493 * Makefile.am: Added iselect.c and iselect.h.
3495 * coop.c (coop_qinit): Initialize fields used by
3496 scm_internal_select.
3497 (coop_qget, coop_qget, coop_tmp_queue): Made global.
3498 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
3499 replacement in iselect.c.
3500 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
3501 coop_join): If GUILE_ISELECT enabled, use
3502 coop_wait_for_runnable_thread instead of
3503 coop_next_runnable_thread.
3504 (usleep, sleep): New replacements for system functions if
3505 GUILE_ISELECT is enabled.
3507 * coop-threads.h: Declare coop_wait_for_runnable_thread.
3509 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
3511 * filesys.c: Added #include "iselect.h". Moved FD-macros to
3512 iselect.h. Implement Scheme level `select' using
3513 scm_internal_select. (See NEWS.)
3515 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
3517 * init.c: Call scm_init_iselect.
3519 * iselect.h, iselect.c: New files. Implements
3520 scm_internal_select. (See NEWS.)
3522 1997-11-27 Tim Pierce <twp@skepsis.com>
3524 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
3525 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
3526 and scm_must_free, since ultimately the string returned will be copied
3527 by scm_makfrom0str anyway. Also, read any characters that may have
3528 been pushed onto the port with scm_ungetc.
3529 * ports.c (scm_generic_fgets): Same as for scm_fgets.
3530 * ioext.c (scm_read_line): Free string after Guilifying it.
3531 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
3533 1997-11-26 Anthony Green <green@hoser.cygnus.com>
3535 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
3537 * gh.h: Safely wrap prototypes for c++ usage.
3539 1997-11-25 Mark Galassi <rosalia@cygnus.com>
3541 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
3542 gh_repl (argc, argv).
3544 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
3546 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
3547 and to invoke scm_shell().
3548 (gh_launch_pad): took out the loading of boot-9.scm from here,
3549 since it is probably best to let the user control that. In fact,
3550 gh_repl() now invokes scm_shell() which does that.
3552 1997-11-23 Mark Galassi <rosalia@cygnus.com>
3554 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
3557 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
3559 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
3560 yesterday's underscore patch. (Thanks to Marius Vollmer for
3563 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
3565 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
3566 DLSYM_ADDS_USCORE is not defined.
3568 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
3570 * gh_data.c (gh_uniform_vector_length):
3571 (gh_uniform_vector_ref): started implementing the uniform types in
3574 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
3576 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
3577 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
3579 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
3581 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
3582 configure.in was changed).
3584 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
3586 * Makefile.am (modinclude_HEADERS): Include readline.h here.
3587 * Makefile.in: Regenerated.
3589 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
3591 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
3592 OPORT is an `open' port, not an output port.
3594 * filesys.c (scm_close, set_element, get_element, scm_chown,
3595 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use

3599 scm_port_column, scm_set_port_column_x, scm_port_filename,
3600 scm_set_port_filename_x, scm_port_mode,
3601 scm_close_all_ports_except, scm_set_current_output_port,
3602 scm_set_current_error_port): Likewise
3603 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
3604 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
3606 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
3607 * backtrace.c (display_backtrace_body): Likewise
3608 * fports (scm_setvbuf): Likewise
3609 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,

3612 * unif.c (scm_uniform_array_write): Likewise
3614 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
3616 Minor problems with substring-related tag changes.
3617 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
3618 exactly what we want to leave in to detect substrings.
3619 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
3620 * tags.h: Fix diagrams and comments describing the S tag bit;
3621 remove vestigial remarks about the D tag bit.
3622 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
3623 * strings.c: Formatting tweaks.
3625 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
3626 variable first; then SCHEME_LOAD_PATH, with a warning message.
3627 (scm_parse_path): New function.
3628 * script.c: Doc fixes.
3630 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
3632 Readline support, from Daniel Risacher.
3633 * readline.c, readline.h: New files.
3634 * init.c: #include "readline.h".
3635 (scm_boot_guile_1): Call scm_init_readline, if we have it.
3636 * Makefile.am (libguile_la_SOURCES): Include readline.c.
3637 * Makefile.in: Regenerated.
3638 * scmconfig.h.in: Regenerated, after change to ../configure.
3640 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3642 * gh.h: gh_vector_set -> gh_vector_set_x
3644 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3646 * gh_data.c (gh_vector_set_x): changed name to make it consistent
3647 with the ! -> _x mapping when going from Scheme to C.
3649 1997-10-19 Mark Galassi <rosalia@cygnus.com>
3651 * gh.h (gh_reverse):
3659 (gh_assoc): added these gh_ functions implemented as macros.
3661 * gh_predicates.c (gh_null_p):
3662 (gh_string_equal_p): added these two missing predicates.
3664 * gh_list.c (gh_append):
3669 (gh_set_cdr_x): added these routines as I go through and try to
3670 complete the picture R4RS functions that should be mirrored in the
3673 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3675 * tags.h (scm_tc7_substring): Changed the comment and code to
3676 conform with the changes below. Folks! We have suddenly two new
3677 free tc7 codes!!! Jummy, jummy!
3679 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
3681 * Makefile.in: Rebuilt.
3682 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
3684 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
3685 * unif.c (scm_vector_set_length_x): Don't handle multibyte

3696 * gc.c (scm_gc_mark): Don't handle mbstrings.
3697 (scm_gc_sweep): Likewise.
3698 * eval.c (SCM_CEVAL): Don't handle mbstrings.

3700 * tags.h (SCM_TYP7SD): Removed.
3701 (SCM_TYP7D): Removed.
3702 (scm_tc7_mb_string): Removed.
3703 (scm_tc7_mb_substring): Removed.
3704 * print.c (scm_iprin1): Handle char printing directly. Don't
3706 Don't include "mbstrings.h".
3707 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
3708 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
3710 Don't include "mbstrings.h".
3711 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
3712 (SCM_SYMBOL_SLOTS): Define as 4.
3713 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
3714 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
3715 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
3716 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
3717 struct.c, threads.c, throw.c, unif.c, variable.c: Use new
3718 ("gen"-less) I/O function names.

3734 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
3735 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
3737 1997-10-12 Mark Galassi <rosalia@cygnus.com>
3739 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
3741 * gh_test_c.c (c_vector_test): some improvements on the vector
3744 * gh.h (gh_vector): this used to exist but do the wrong thing.
3745 Now it (almost) does the right thing, though it takes a list
3746 instead of the individual arguments. I need to see how it could
3748 (gh_list_to_vector): added this function as a macro. Corresponds
3749 to Scheme's (list->vector ...).
3750 (gh_vector_to_list): added this function as a macro. Corresponds
3751 to Scheme's (vector->list ...).
3753 * gh_data.c (gh_vector_ref): renamed from gh_vref to
3754 gh_vector_ref, so that it resembles the Scheme routines more.
3755 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
3756 resembles the Scheme routines more.
3757 (gh_make_vector): this used to be (stupidly) called gh_vector().
3758 This is the right name, since it does the same thing as the Scheme
3759 (make-vector ...) procedure.
3761 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
3763 * ports.h: #include "libguile/print.h"
3765 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
3766 Some indentation fixes.
3768 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
3769 longer a user field; New field: class_flags.
3771 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
3773 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
3775 * gh_data.c (gh_bool2scm): new function which replaces
3776 gh_int2scmb(), which is now tagged as obsolete.
3778 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
3780 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
3781 macros should by convention not test for NIMPness.)
3782 (SCM_COERCE_OPORT): Adjust indentation.
3784 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
3785 SCM_NIMP test before SCM_PRINT_STATE_P.
3787 * struct.c, struct.h, gc.c: Renamed:
3788 scm_struct_i_layout --> scm_vtable_index_layout
3789 scm_struct_i_vcell --> scm_vtable_index_vcell
3790 scm_struct_i_vtable --> scm_vtable_index_vtable
3791 scm_struct_i_printer --> scm_vtable_index_printer
3792 scm_struct_i_vtable_offset --> scm_vtable_offset_user
3794 * struct.c (scm_print_struct): Use new printer slot; Default
3795 printing: Also output hex code of vtable so that type identity
3796 will be indicated as well.
3797 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
3798 Removed struct_printer_var; Removed struct-vtable-offset;
3799 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
3800 vtable-offset-user): New constants.
3802 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
3803 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
3804 If this slot contains a procedure, use that to print structures of
3805 the type represented by this vtable.
3807 * print.c (scm_iprin1): Don't print arguments of macro
3808 transformers. (They are always: exp env.); Bugfix: Unmemoize
3809 transformer source with correct environment.
3811 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
3813 Streamlining of call-with-dynamic-root:
3815 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
3816 there is now only one catch.
3817 (cwdr_outer_body): Removed.
3818 (cwdr_handler): New function.
3819 (scm_internal_cwdr): New function to perform the function of cwdr
3820 but take args that are more useful to C code. Also, the handler
3821 is now invoked *outside* of the new dynamic root, like the docs
3822 say. We no longer have to catch absolutely all errors, the caller
3823 is responsible for using a handler that does not throw, if he
3825 (cwdr): Reimplemented in terms of scm_internal_cwdr.
3826 * root.h (scm_internal_cwdr): New prototype.
3828 Even more but risky streamlining:
3830 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
3831 allocation of the jumpbuf of a root continuation. The changes
3832 below are controlled by it. They are now deactivated.
3833 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
3834 the JMPBUF of the scm_rootcont to NULL before returning.
3836 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
3837 when they are non-NULL.
3838 (scm_gc_mark): Likewise, mark only when non-NULL.
3840 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
3841 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
3843 * gc.c (scm_done_malloc): New function.
3844 gc.h (scm_done_malloc): New prototype.
3846 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
3847 (struct scm_print_state) [revealed]: New field.
3848 (scm_print_state_vtable): Make visible to the outside world for
3849 type checking purposes.
3850 (scm_valid_oport_value_p): New prototype.
3852 * print.c (scm_valid_oport_value_p): New function to check whether
3853 a certain value is acceptable as a port argument.
3854 (scm_print_state_vtable): New variable.
3855 (scm_free_print_state): Set `revealed' field to false.
3856 (scm_iprin1): Call user supplied closure printer with
3857 scm_printer_apply. Print in the traditional way when there isn't
3858 one or when it returns #f.
3859 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
3860 Accept a port/print-state pair in addition to just a port.
3861 (scm_prin1): Don't return the print_state to the pool when it has
3863 (scm_printer_apply): Set `revealed' field of print_state to true.
3864 (scm_init_print): Set scm_print_state_vtable.
3865 (print_state_fluid, print_state_fluid_num): Removed.
3867 * throw.h (scm_handle_by_proc_catching_all): New prototype
3868 throw.c (scm_handle_by_proc_catching_all): New function
3870 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
3872 * Makefile.in: Regenerated with automake 1.2c.
3874 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
3876 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
3877 was looping endlessly.
3879 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
3881 * strports.c (scm_eval_string): Don't close the port.
3883 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
3884 former returns a nice normal integer. (Thanks to Daniel
3887 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
3889 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
3890 makefile variable as a build parameter called LIBS. The
3891 build-guile program will use this, for the time being.
3892 * Makefile.in: Regenerated.
3894 Thanks to Shiro Kawai:
3895 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
3896 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
3899 * Makefile.in: Regenerated with automake 1.2a.
3901 * script.c (scm_compile_shell_switches): If we hit the -c or --
3902 arguments, don't set the car of (command-line) to scm_usage_name,
3903 the prettified name of the guile executable; give it the full
3904 path, the way shells usually handle $0.
3906 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3908 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
3909 Scheme-level name `array-map' and renamed `serial-array-map' to
3910 `serial-array-map!'.
3912 * backtrace.c: Introduced exception handlers which now enclose
3913 `display-error' and `display-backtrace' so that error reporting
3914 won't get into infinite loops if an error occurs during displaying
3915 of the error. This can very easily happen with user supplied
3916 print call-back routines.
3918 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3920 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
3921 the names `serial-array-map' and `array-map' should be removed.)
3923 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
3925 * init.c (scm_boot_guile_1): Added scm_init_objects ().
3926 Added #include "objects.h"
3928 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
3929 Add #include "feature.h".
3931 * Makefile.am (libguile_la_SOURCES): Added objects.c.
3932 (modinclude_HEADERS): Added objects.h.
3934 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
3935 This test is needed at many places in the code and should be
3936 abstracted. (Motivated by the need of this test in libguiletk.)
3938 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
3939 (scm_eval_string), load.c (scm_primitive_load,
3940 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
3941 Use SCM_EOF_OBJECT_P.
3943 * eval.c (scm_init_eval): Add feature `delay'.
3945 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3947 * scmhob.h: Removed.
3949 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3951 * list.h (SCM_LISTn): New macros. Make list creation in C code
3952 prettier. The idea comes from STk.
3954 * sequences.h, sequences.c, append.h, append.c: Removed. These
3955 files implemented non-R4RS operations which would encourage
3956 non-portable programming style and less easy-to-read code.
3958 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
3961 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
3962 sequences.h, #include append.h.
3964 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
3967 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
3969 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
3971 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
3973 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3975 * eval.c: Added #include "objects.h"
3977 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
3980 * smob.c (scm_smob_prehistory): Create two objectsmobs with
3981 adjacent smob numbers.
3983 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3985 * procprop.h: Added declaration of scm_i_inner_name.
3987 * gsubr.c: New global symbol scm_i_inner_name.
3989 * debug.c (scm_procedure_name): Try procedure property
3990 `inner-name' if `name' fails.
3992 * print.c (scm_iprin1): Use scm_macro_name.
3994 * eval.c (scm_m_define): Give names to macros as well; Only the
3995 first top-level definition gives a procedure/macro a name.
3996 Otherwise confusing names can turn up in backtraces.
3997 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
3998 `name'; Give names to macros as well.
4000 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
4001 (scm_macro_transformer): Use SCM_CLOSUREP instead of
4004 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4006 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
4008 (prinmacro): Removed. The code has been moved/merged into print.c
4009 in order to decrease code redundancy. We want macros to print in
4010 a way equivalent to procedures, and it would be silly to duplicate
4011 the required code. (We don't want to maintain two places.)
4012 (macrosmob): Print field is now a NULL pointer.
4014 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
4015 scm_macro_transformer): New prototypes.

4030 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
4032 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,

4040 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
4041 scm_gensym): Added prototypes.

4061 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
4063 * Makefile.in: Regenerated, so it uses "tar", not "gtar".

4076 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
4077 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,

4088 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4090 * list.c (scm_list_append_x): Allow non-pair as last argument.
4091 This is consistent with the R4RS append and is probably the
4092 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
4094 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4096 * stime.h: prototype for scm_times.
4097 * stime.c (scm_times): new procedure.

4114 third argument is now optional.
4116 * posix.c (scm_execl, scm_execlp): make the filename argument
4117 compulsory, since omitting it causes SEGV.
4118 (scm_sync): return unspecified instead of #f.
4119 (scm_execle): new procedure.
4120 (environ_list_to_c): new procedure.
4121 (scm_environ): use environ_list_to_c. disable interrupts.
4122 (scm_convert_exec_args): take pos and subr arguments and
4123 improve error checking.
4125 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4127 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
4128 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
4129 argument to SCM_ASSERT. Furthermore, the name of the function
4130 should be passed as first argument when signalling
4131 SCM_WNA. (Thanks to Thomas Morgan)
4133 * gsubr.c (scm_gsubr_apply): From Radey Shouman
4134 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
4135 dispatches on the number of actual args has a default case
4136 reporting an internal error. This is a vestige from a version
4137 that mallocated a SCM vector to hold the arguments. In the
4138 current version this check is too late: if it ever happens we will
4139 have already overstepped the bounds of the array.
4141 Also, the patch [...] adds a check for too many actual arguments."
4143 mdj: Removed check for "internal programming error".
4145 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4147 * gh_io.c (gh_write): New function.
4149 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:

4162 fold in the functionality of scm_primitive_dup.
4163 (scm_primitive_dup): deleted.

4168 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
4169 ultrix are defined. Use setvbuf instead of setbuf.

4186 (scm_init_print): Initialize them.
4187 (scm_iprin): If print_state_fluid carries a print_state, use that
4188 instead of creating a new one.

4190 definitions to help with calling printer functions written in
4192 * print.h (scm_printer_apply): New prototype.

4205 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
4206 SCM_ASSERT: arg comes before pos.
4208 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4210 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
4211 to a list of length zero correctly.
4213 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

4235 stream has been set.
4236 (scm_duplicate_port): deleted, there's now an implementation in

4289 data. (dynl_smob): Use it.
4290 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
4291 the dynamic object data below the linking of the object to avoid
4292 memory leak when the linking code throws an error. Now the code
4293 leaks a whole dynamically linked library when must_malloc throws,
4294 but that should be much less likely.
4296 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
4298 Changes to compile under gnu-win32, from Marcus Daniels:

4339 DEBUG_EXTENSIONS isn't #defined.
4341 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>

4369 turn off REG_EXTENDED.
4370 (scm_init_regex_posix): New regexp/basic symbol.
4371 (REG_BASIC): #define this if it is not already present.

4418 (cwdr_outer_body): New function, to establish the user's handler,
4419 and pass control to cwdr_inner_body.

4431 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
4432 the feeling that real thread systems will not need this...
4434 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
4436 Try to detect when people are using one version of libguile and a

4475 * extchrs.h (xmbtowc): Corresponding change to prototype.
4476 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
4478 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
4479 argument plain char *.
4480 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
4482 * tag.c (scm_tag): Remove unreachable statement.
4483 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
4484 top of the word, it should be unsigned.
4486 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
4487 is defined, to avoid warnings; it's only used in the
4488 conflict-checking code. Which might go away anyway.
4489 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
4490 conditionals; put the label definition in an #if too, to stifle
4493 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
4494 ChangeLog-threads in the distribution.
4495 * Makefile.in: Regenerated.
4497 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4499 * guile-snarf.in: Changed regexp to support CPPs that insert
4500 whitespace between lexical tokens (which munges the `%%%' snarf
4503 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4505 * load.c (scm_init_load_path): Append $(datadir)/guile to
4506 %load-path, so modules do not have to be installed in Guile's
4507 current version directory.
4509 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
4511 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
4512 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
4513 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
4514 call the sysdep functions with deferred ints.
4515 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
4516 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
4517 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
4520 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
4523 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
4525 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
4527 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
4529 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
4532 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
4534 * eval.c (scm_lookupcar1): New procedure to cope with a race
4535 condition during lookup (when using threads).
4536 (scm_lookupcar): Implement in terms of scm_lookupcar1.
4537 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
4540 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
4542 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
4543 supplied. (Change from Tim Pierce.)
4545 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
4547 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
4548 23:47:01 1997" changelog: Slots are now initialized with `#f' by
4549 default and not `()'. `#f' is the canonical non-value in Scheme,
4552 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4554 * struct.c (struct_printer): New variable that holds a handle on
4555 the Scheme variable *struct-printer*. This variable can be set by
4556 Scheme code to override the printing of structures.
4557 (scm_print_struct): If struct_printer is set, call it. If it is
4558 not set, or returns #f, print the structure in the old fashion.
4559 Include "eval.h" for scm_apply.
4561 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
4563 * struct.c (scm_struct_ref, scm_struct_set_x): Use
4564 scm_struct_i_n_words to get the number of fields, not
4565 -scm_struct_n_extra_words.
4567 On the route to fancier struct printing:
4568 * struct.c (scm_print_struct): New function to print a structure.
4569 Include "genio.h" to support it. This function doesn't do
4570 anything interesting right now, but I think it should be here
4572 * struct.h: Include "print.h" and add prototype for
4574 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
4575 print structures ourself.
4577 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4579 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
4580 before applying the handler in case it doesn't return.
4582 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
4584 * scmsigs.h, async.h: updated.
4586 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
4589 * posix.c (scm_uname): interpret only negative values as an error.
4590 Solaris normally returns a positive value.
4592 * script.c (scm_compile_shell_switches): if we are not going into
4593 an interactive repl, set scm_mask_ints to zero so that asyncs can
4596 * simpos.c (scm_system): don't ignore/unignore signals around
4599 * posix.c (scm_open_pipe): don't ignore/unignore signals around
4602 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
4603 done in boot-9.scm instead.
4605 * scmsigs.c, async.c: Major rewriting of signal handling code.
4606 (scm_sigaction): new procedure.
4607 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
4609 (scm_raise): return unspecified, throw error on failure.
4611 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4613 * regex-posix.c (scm_init_regex_posix): Register the "regex"
4614 feature, to help boot-9.scm decide whether to import the regex
4617 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
4619 * eval.c: Include scmconfig.h at the beginning of the file so that
4620 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
4623 * regex-posix.c: #include "_scm.h" before conditionally #including
4624 <regex.h>; the former defines HAVE_REGCOMP.
4626 * regex-posix.c: #include <regex.h> conditionally, so the file is
4627 CPP'able (for dependency scanning) even on systems that don't have
4630 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
4632 Add new R4RS-compliant syntax for keywords.
4633 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
4634 regardless of the setting of the `keywords' read option.
4635 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
4636 can be re-read no matter what the setting of the `keywords' read
4639 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
4641 Add support for POSIX regular expressions.
4643 * regex-posix.c, regex-posix.h: New files. (Some code
4644 is taken liberally from rx/rgx.c in the old Guile dist.)
4646 * init.c: Include regex-posix.h.
4647 (scm_boot_guile_1): Call scm_init_regex_posix.
4649 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
4650 Add regex-posix.[ch] sources.
4651 * Makefile.in: Regenerated.
4653 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
4654 to do this automatically? It didn't for me, bleh.)
4656 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
4658 * fports.c (print_pipe_port): New function.
4659 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
4660 latter doesn't even take the right arguments.
4662 * Makefile.am: Increment shared lib revision number. I think
4663 sometimes the uninstalled Guile finds the installed shared lib;
4664 Gord says doing this might help. As things turned out, I can't
4665 say whether it does.
4666 * Makefile.in: Regenerated.
4668 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
4669 passing it as the closure argument to scm_boot_guile. (Bill
4672 * ports.c (print_void_port, putc_void_port, puts_void_port,
4673 write_void_port, flush_void_port, getc_void_port, close_void_port,
4674 noop0): Use ANSI prototypes instead of K&R declarations, so the
4675 initialization of void_port_ptob gets aggressively type-checked.
4676 Fix arguments of print_void_port and write_void_port. (Bill

4710 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
4712 * script.c (scm_find_executable): Use prototype-style definition
4713 here; apparently it's not quite right to have const in a prototype
4714 and then use a K&R declaration. I wonder if stuff like this will
4715 go away if we compile with -Wrequire-prototypes, or whatever that
4716 is... (Bernard URBAN)
4718 * scmhob.h: New text from Bernard URBAN.
4720 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4722 * script.c: Don't #define const on hpux. Configure takes care of
4723 this. (Thanks to Larry Schwimmer.)
4725 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
4726 decide whether to #include <unistd.h>, instead of listing a bunch
4727 of systems. Don't #include stdio twice. Removed dyked-out
4728 definition of scm_find_impl_file.
4730 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
4732 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
4733 library version info to 1:0.
4734 * Makefile.in: Regenerated.
4736 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

4740 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
4741 throw.c: Update copyright years; these files have been worked on
4742 significantly in 1997, but only had copyright years for 1996.
4743 Also, change name of copyright holder on some from Mikael
4744 Djurfeldt to Free Software Foundation; he has signed papers
4745 assigning the changes to the FSF.
4747 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
4748 reason not to give the user the option.
4750 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
4751 Return #f on end-of-file when scanning table (i.e. when called
4752 with no arguments). Try to catch errors, when we can.
4753 * posix.c (scm_getgrgid, scm_getpwuid): Same.
4755 * script.h (scm_shell_usage, scm_compile_shell_switches): New
4756 external declarations. These are useful.
4758 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
4760 * posix.c: don't include <sys/select.h> or define macros for
4761 select, since they were not used in this file.
4763 * filesys.c (scm_select): make the fifth parameter microseconds,
4764 not milliseconds. let the fourth parameter be either a real value
4765 or an integer or #f. The first, second and third arguments can
4766 now be vectors: the type of the corresponding return set will be
4768 (set_element, get_element): new static procedures.
4770 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
4772 * strports.c (scm_eval_string): New function.
4773 (scm_eval_0str): Trivially re-implemented in terms of
4775 * strports.h (scm_eval_string): New extern decl.
4777 * net_db.c (h_errno): Add extern decl for this.
4779 * fports.c (local_pclose): New function.
4780 (scm_pipob): Use it in the initializer here.
4783 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
4784 Use a meaningful error message when signalling an error. For
4785 this, scm_gethost must check h_errno rather than errno.
4787 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
4789 * Makefile.in: Regenerated, using automake-1.1p.
4791 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
4793 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
4794 not SCM_UNSPECIFIED.
4796 * script.c (scm_compile_shell_switches): don't append (quit) if
4798 (scm_shell): call scm_exit_status and exit on the result of the
4801 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
4803 Ensure that shared substrings are handled properly when passed to
4804 a system call or other foreign function. Many thanks to Tim
4806 * symbols.h (SCM_COERCE_SUBSTR): new macro.
4807 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
4808 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
4809 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

4814 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,

4820 scm_strftime), vports.c (scm_make_soft_port): use
4821 SCM_COERCE_SUBSTR to make sure shared substrings are
4824 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
4826 * error.c (scm_error): Add newline to error message.
4828 * init.c (scm_init_standard_ports): Doc fix.
4830 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4832 * dynl-shl.c: Completely replaced with new code from Bernard
4835 * script.c (scm_ice_9_already_loaded): New variable.
4836 (scm_compile_shell_switches): Use it.
4838 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4840 * filesys.c (scm_input_waiting_p): add missing third argument to
4843 * stime.c (scm_localtime): copy the result of localtime before
4844 calling gmtime in case they share a buffer.
4845 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
4848 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
4850 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
4852 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
4854 * Makefile.am (check-local): New target, which causes 'make check'
4855 to run gh_test_c and gh_test_repl, with some trivial input.
4856 * Makefile.in: Rgnrtd.
4858 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
4860 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
4863 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
4865 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
4866 sure how this was supposed to work.
4867 (scm_async_click): don't send SCM_TICK_SIGNAL.
4868 (scm_init_async): don't initialize %tick-thunk.
4870 * the following change doesn't affect the Scheme interface:
4871 gc-thunk is called at the end of garbage collection. however it's
4872 no longer implemented by pretending it's a signal.
4874 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
4875 system async corresponding to scm_gc_thunk.
4876 * async.h: declare scm_gc_async.
4877 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
4878 gc-thunk directly, instead of going through a signal handler.
4879 (scm_gc_async): new variable, points to the GC system-async.
4880 (scm_init_async): save the GC async as scm_gc_async instead
4881 of using system_signal_asyncs.
4882 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
4884 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
4886 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
4887 Don't screw up if we're interrupted.
4888 * Makefile.in: Regeneradet.
4890 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
4892 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
4894 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
4895 we're not using AM_INIT_GUILE_MODULE any more.
4896 * Makefile.in: Reneregated.
4898 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
4900 Functions for finding variable bindings, grace à Tim Pierce.
4901 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
4902 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
4904 Get 'make dist' to work again.
4905 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
4906 * Makefile.in: Regenerated, like a surry without a fringe on top.
4908 Changes for reduced Guile distribution: one configure script,
4910 * configure.in, configure: Removed.
4911 * acconfig.h, acinclude.m4: Moved to parent directory, where the
4912 real configure script lives.
4913 * Makefile.in, scmconfig.h.in: Regenerated.
4915 * init.c: #include "script.h", to get prototype for script.c's
4918 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
4920 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
4921 scm_must_malloc, not raw malloc.
4923 * script.c (scm_compile_shell_switches): Dyke out debugging output
4926 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4928 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
4930 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
4931 system has them. Hope this is safe. Previously
4932 sys/timeb.h was included if HAVE_FTIME was defined or if
4933 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
4934 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
4936 * ioext.c (scm_setfileno): add missing third argument to
4937 scm_misc_error call.
4939 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
4941 * eq.c (scm_equal_p): Correctly compare strings of different
4942 varieties. (Thanks to Tim Pierce.)
4944 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
4946 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
4947 #! block comment must occur on a line all by itself.
4949 Move most of the guts of shell command processing into libguile,
4950 so guile.c can be very small (and eventuallly auto-generated. (I
4951 mean, generated mechanically, not self-generated. Hmm.))
4952 * guile.c, script.c, script.h: New source files.
4953 * init.c (scm_boot_guile_1): Call scm_init_script.
4954 * libguile.h: #include "script.h".
4955 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
4956 targets, for new executable.
4957 (libguile_la_SOURCES): Mention script.c.
4958 (modinclude_HEADERS): Add script.h.
4959 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
4960 not dynamic linking is enabled. This is because we're generating
4961 executables now. Move CY_AC_WITH_THREADS call after those, so the
4962 values of cy_cv_threads_libs captures the libs chosen above.
4963 * Makefile.in, configure, aclocal.m4: Regenerated.
4965 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
4966 We don't maintain this interface any more, and it just confuses
4969 * alloca.c: #include <scmconfig.h>, not <config.h>.
4970 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
4971 it'll get included in disties.
4973 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
4975 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
4976 be distributed, because they confuse people.
4977 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
4979 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
4981 * configure.in: check for presence of gethostent (not present on
4982 OpenBSD by default).
4983 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
4984 * configure, scmconfig.h.in: Regenerated.
4986 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
4988 * backtrace.c (scm_backtrace): Split message string across
4989 newlines properly. GCC is more tolerant of this than other

4998 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
5000 (modinclude_HEADERS): Add threads.h, coop-defs.h.
5001 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5002 coop-threads.c.cygnus, coop-threads.h.cygnus.
5003 * configure.in: If we're using threads, include threads.o in
5005 * _scm.h, libguile.h: threads.h lives in this directory now.
5006 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5007 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
5008 currently used, but brought along for information's sake.
5009 * ChangeLog-threads: log from old 'threads' directory.
5010 * Makefile.in, configure: Rebuilt.
5012 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
5014 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
5017 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
5019 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
5021 Merge GH interface library into libguile.

5023 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
5024 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
5025 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
5027 (EXTRA_libguile_la_SOURCES): ... here.
5028 (pkginclude_HEADERS): Add variable, to get gh.h installed.
5029 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
5030 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
5031 New variables, describing how to build the gh test programs.
5032 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
5033 build the test programs, and we probably should have been linking
5034 libguile.la against them all along, to support AIX shared libs.
5035 Add cflags for threads to CFLAGS; add libs for threads to new
5036 variable THREAD_LIBS, used in Makefile.am.
5037 * ChangeLog-gh: log from old `gh' subdirectory.
5038 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
5040 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
5042 * acconfig.h: Undo change of Apr 9; including the definition of
5043 PACKAGE in the guile headers conflicts with applications' own
5045 * scmconfig.h.in: Regenerated.

5056 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
5058 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
5059 have S_IFSOCK. This is the case under Ultrix.
5061 * posix.c (scm_status_exit_val, scm_status_exit_val,
5062 scm_status_term_sig, scm_status_stop_sig): Modified to work with
5063 Ultrix versions of WIFSTOPPED, etc., which assume that their
5064 arguments are lvalues (hmm).
5066 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5068 * eval.c: Doc fixes.
5070 * throw.c: Doc fixes; rearranged.
5072 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.

5076 * acconfig.h: Added entry for PACKAGE.
5077 * scmconfig.h.in: Regenerated.

5080 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5081 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
5083 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
5085 * Makefile.in: Rebuild.
5087 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5089 * stime.c (scm_mktime): take an optional zone argument.
5090 (scm_localtime): check putenv return value.
5091 (scm_strftime, scm_strptime): moved from posix.c. move #include
5093 stime.h, posix.h: update prototypes.
5094 (bdtime2c, setzone, restorezone): new static procedures.
5095 (scm_mktime, scm_strftime): use them.
5096 (scm_strftime): don't call mktime before strftime. Use
5097 filltime for return value.
5098 (filltime): convert NULL zname to #f.
5099 (scm_strptime): return a count of characters consumed, not
5100 the remaining string.
5102 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5104 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
5105 (scm_mktime): likewise.
5107 Uncomment localtime and mktime.
5109 * configure.in: add AC_STRUCT_TIMEZONE.
5111 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5113 * stime.c (scm_init_stime): don't define ticks/sec.
5114 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5115 return value problem and is still portable.)
5117 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5119 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
5120 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5121 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
5122 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
5123 cpp_err_symbols.c): Corresponding changes.
5124 * Makefile.in: Regenerated.
5126 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5128 * posix.c (scm_putenv): don't check HAVE_PUTENV.
5129 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
5130 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
5131 * putenv.c: new file, from sh-utils 1.12.
5133 * posix.c (scm_environ): use malloc in place of scm_must_malloc
5134 since allocation isn't for Scheme objects.
5135 (scm_putenv): copy strings before placing in the environment.
5137 * stime.c (scm_current_time): throw an error if time returns -1,
5138 instead of returning #f.
5139 (scm_get_internal_real_time, scm_get_internal_real_time): use
5140 scm_long2num for return value instead of SCM_MAKINUM.
5142 * stime.h: prototypes updated.
5144 * stime.c (scm_time_in_msec): apparently unused, deleted.
5146 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5148 * configure.in: check for gettimeofday.
5150 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
5151 which may be more usefully portable than a gettimeofday interface.
5153 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
5155 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not

5159 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5161 * stime.c (filltime): recovered static procedure.
5162 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from

5166 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5168 * posix.c (scm_mknod): split the mode argument into type and perms
5169 arguments, like the extra fields returned by stat.
5171 * fports.c (scm_pipob): set the close, free and print procedures.
5172 (scm_close_pipe): new procedure.
5174 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5175 define them in boot-9.scm
5177 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5179 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5180 wan't defined. Don't include fd.h.
5182 * Previously fd.h was regenerated whenever configure was run,
5183 forcing a couple of files to be recompiled.
5185 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5186 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5187 Check for _fileno as well as _file.
5189 * ioext.c: don't fd.h.
5190 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5193 * Change the stratigy for getting information about errno
5194 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5195 generating lists of symbols during the build process, which will
5196 not always work, include comprehensive lists in the distribution.
5197 To help keep the lists up to date, the "check_signals" and
5198 "check_errnos" make targets can be used.
5200 * configure.in: don't check for a command to extract errno codes.
5201 * Makefile.am: update file lists, remove errnos.list and errnos.c
5202 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5203 check_errnos targets.
5204 (CLEANFILES): remove errnos.c and errnos.list, add
5205 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
5206 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
5207 * errnos.default: deleted.

5210 * cpp_err_symbols, cpp_sig_symbols: new files.
5211 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
5212 * error.c (scm_init_error): #include cpp_err_symbols instead of
5214 * posix.c (scm_init_posix): don't intern signal symbols. #include
5217 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5219 * strop.c (scm_i_index): allow the lower bound to be equal to the
5220 length of the string, so a null string doesn't always give an error.
5222 * posix.h: new prototypes.
5223 * posix.c (scm_status_exit_val, scm_status_term_sig,
5224 scm_status_stop_sig): new functions, as in scsh. They break down
5225 process status values as returned by waitpid.
5227 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
5229 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
5230 configure doesn't know about it.
5232 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5234 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
5236 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
5237 which defines C variables with global linkage.
5239 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5241 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
5244 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
5246 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
5247 has time to check why this doesn't work well with continuations.
5249 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
5251 * Fix shell syntax error; some shells won't tolerate
5252 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
5254 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5256 * posix.c (scm_uname): throw an error if uname fails instead
5259 * error.h (scm_errno, scm_perror): obsolete prototypes removed.

5268 * acconfig.h: Removed PACKAGE.
5270 * scmconfig.h.in: Regenerated.
5272 * snarf.h: g++ says it's non-portable not to specify the first
5273 argument in a varargs declaration. I introduced the first
5274 argument by using preprocessor conditionals.
5276 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
5278 * ioext.c (scm_read_delimited_x): use RO string macros for delims.

5308 * error.h: prototype for scm_error_scm.
5310 * error.c (scm_error_scm): new procedure, reimplements scm-error
5311 in C and uses scm_error.
5313 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5315 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5316 pointer to the Scheme variable read-hash-procedures and intern it
5317 in scm_init_read. Modify scm_read_hash_extend and
5318 scm_get_hash_procedure to use the pointer.
5320 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5322 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5323 (SCM_KEYWORD_STYLE): defined.
5325 * read.c (scm_read_opts): add a keywords option. This isn't a
5326 boolean option, in case someone wants to add support for DSSSL
5328 Setup scm_keyword_prefix symbol.
5329 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5331 I've left keyword support disabled by default, since it doesn't
5332 seem to break the module system and it gives R4RS standard behaviour.
5333 It can be reactivated with (read-set! keywords 'prefix).
5335 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5337 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS

5350 (idea from Mikael: make it a pair so scm_permanent object only
5352 (scm_read_hash_extend): don't call scm_permanent_object.
5353 (ideas from Mikael): if chr is already in the list, replace its
5354 procedure instead of appending it again. If proc is #f, remove
5356 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5358 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.

5386 (default_case_i): definition removed.
5387 * read.c (scm_read_token): if case_i, downcase ic before doing
5390 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5392 * configure.in: Added configuration option `guile-debug'.
5393 Configure with --enable-guile-debug if you want a bunch of extra
5394 functions used for debugging when developing Guile.
5396 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
5398 * procs.c (make-cclo): New undocumented debugging procedure: Make

5411 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5413 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
5414 with 3 or more args internally to the evaluator. This is mainly
5415 because we don't want to pass entry and exit points of the
5416 debug support twice, but it also seems to increase the speed of
5417 the evaluator for such calls (e. g. (+ 1 2 3)).
5419 * backtrace.c (scm_display_application): New procedure:
5420 display-application; Set fancy printing parameters individually
5421 for different types of display (backtrace, error, application).
5422 (These should of course be customizable!)
5424 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
5425 clear the CHECK-flags.
5427 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5429 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5431 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5433 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
5434 from pairs with a GLOC in the car.
5436 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
5437 otherwise `symbol-hash' will behave badly.
5438 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
5439 we get segmentation fault!
5441 * symbols.c: Added #include "weaks.h". New functions:
5442 `builtin-bindings' and `builtin-weak-bindings'. (These will be
5443 moved to an extraneous library when we split libguile.)
5445 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5447 * filesys.c (scm_stat): stat now takes fport arguments too as
5448 documented in the manual.
5450 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5452 * debug.c (scm_single_step): Bugfix: Call continuation with
5453 scm_call_continuation instead of throwing to it.
5455 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
5457 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
5458 argument wasn't declared to be optional.
5460 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5462 * stime.c (scm_init_stime): Add feature "current-time".
5464 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5466 * throw.h: prototype for scm_exit_status.
5467 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
5468 args to derive an exit status. Allows (quit) to work from a
5470 (scm_exit_status): new function.
5473 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5475 * eval.c (scm_deval): Removed some old code.
5476 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
5478 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
5481 * symbols.c (msymbolize): Bugfix: Must initialize property list to
5484 * procs.c: Introduce the existent C function scm_thunk_p at the
5485 Scheme level as well.
5487 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5489 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
5490 used from C to easily lookup the value of a symbol in the current
5493 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5495 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
5496 scm_init_unif in this file. This will also fix a previous problem
5499 * configure.in: Added AM_MAINTAINER_MODE
5501 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5503 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
5506 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5508 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
5509 source files that are not always included in libguile but should
5510 have their dependencies calculated by automake. This variable is
5511 recognized by automake, no further magic is needed.
5512 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
5513 to deal exclusively with *.lo files, as it seems. The *.o files
5514 are built automatically when the corresponding *.lo file gets
5517 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
5519 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
5522 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
5524 * unif.c (scm_array_set_x): minor change to argument error checking.
5526 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
5528 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
5529 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
5530 They should only be included in the library at configure.in's
5532 (libguile_la_LDADD): Include the appropriate .lo files here.
5533 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
5534 so we know when to build them (and their .lo bretheren).
5535 * configure.in (LIBLOBJS): New substituted variable. We let
5536 configure decide which .o files to include in LIBOBJS, and then
5537 put the corresponding list of .lo files in LIBLOBJS. The latter
5538 is what we pass to libtool.
5539 * Makefile.in, configure: regenerated.
5541 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
5543 * symbols.c (scm_sysintern0): New function. Contains the core of
5544 old scm_sysintern but doesn't take a second value argument.
5545 (scm_sysintern): Now uses scm_sysintern0.
5546 (scm_sysintern_no_module_lookup): Renamed to
5547 scm_sysintern0_no_module_lookup and doesn't take a second value
5548 argument any longer.
5550 * symbols.h (scm_sysintern0: Added declaration.
5552 * options.c (scm_init_opts): Use scm_sysintern0 instead of
5553 scm_sysintern when interning option keys. Otherwise we risk
5554 destroying the values of already interned variables.
5556 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
5557 scheme-level boolean (use SCM_NFALSEP).
5559 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
5561 (scm_backtrace): New function. (C version of old function from
5562 boot-9.scm) Motivation: Make it possible to display backtraces
5563 without depending on boot-9.scm. (I'm uncertain if this
5564 motivation is good enough...)
5566 * root.h (scm_root_state): Add member the_last_stack_var.
5567 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
5569 * root.c (mark_root): Mark scm_the_last_stack_var.
5571 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
5574 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
5576 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
5577 1. mark_lazy_catch didn't mark the smob.
5578 2. Both functions above have standard variants:
5579 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
5580 free_lazy_catch --> scm_free0.
5582 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
5584 * throw.c (scm_internal_lazy_catch): New function.
5585 (scm_lazy_catch): Rewritten to use it.
5586 (scm_ithrow): Handle the new lazy catch representation.
5587 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
5588 that doesn't have a jmpbuf is a lazy catch clause.
5589 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
5590 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
5591 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
5593 (scm_init_throw): Register the new lazy-catch smob type.
5594 * throw.h (scm_internal_lazy_catch): decl for new function.
5596 * throw.c (scm_internal_catch): Doc fixes.
5598 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
5599 configure.in. Including this might cause problems if applications
5600 that link against libguile include their own copies of alloca, but
5601 if they're using autoconf, they should be adding libguile to LIBS
5602 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
5603 the copy in libguile, and things will be okay. (I think.)
5605 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5607 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
5609 strop.h: move prototypes too.
5611 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5613 * posix.c (scm_init_posix): don't intern EINTR since it's now done
5616 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
5617 etc. I deleted them from filesys.c long ago, but didn't
5618 notice they were here too (although ineffective since
5619 sys/stat.h wasn't included).
5621 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
5623 * eval.c: Don't define alloca in GCC case. gcc will automatically
5624 use __builtin_alloca if appropriate.
5626 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5628 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
5629 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
5630 that values of automatic variables are preserved. See comments
5631 for safe_setjmp for details.
5633 Change from Thomas Morgan:
5634 * variable.c: Include eq.h.
5635 (var_equal): New function.
5636 (variable_smob): Use var_equal as the discriminator for variables.
5638 * throw.c (s_throw): Remove extraneous declaration.
5640 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
5641 * eval.c: Add necessary CPP cruft to support that.
5642 * configure, Makefile.in, scmconfig.h.in: regenerated.
5644 Change from Thomas Morgan:
5645 * procprop.c (scm_procedure_properties): Convert the Scheme
5646 boolean returned by scm_procedure_p into a C boolean before using
5647 it as a condition for SCM_ASSERT.
5648 (scm_procedure_property): Likewise.
5650 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
5651 indications of Unixness.
5654 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5656 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
5658 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5660 * read.c (scm_lreadr): use scm_misc_error to improve one of the
5661 "unknown # object" error messages.
5663 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
5664 (scm_i_index) and declare it static. Add a 'direction' argument
5665 to indicate what way the search should go.
5666 (scm_i_index): throw out-of-range error instead of wrong-type-arg
5668 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
5669 strop.h: remove scm_i_index, scm_i_rindex prototypes.
5671 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5673 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
5675 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
5676 to avoid clash with various scsh forks.
5678 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
5680 The following two changes (ramap.c, throw.c) are motivated by the
5681 apparent unportability of forward declarations of static arrays of
5682 the form `static foo bar[];'.
5684 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
5685 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
5687 * throw.c (scm_throw): Moved above scm_ithrow.
5689 * options.h: Removed the extern declarations of scm_yes_sym and
5690 scm_no_sym since these are static.
5692 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5694 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
5696 * Makefile.am: remove AWK=@AWK@.
5697 Add a rule for generating errnos.list.
5698 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
5700 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
5701 don't extract errnos, just set a variable (avoids the
5702 need to recompile error.c just because configure is run.)
5704 * unif.h: update prototypes.
5705 * unif.c (scm_uniform_array_read,write): change the offset and
5706 length arguments to start and end, for consistency.
5708 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
5710 * ioext.h: update prototypes.
5711 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
5712 scm_read_line_x, it's a more general procedure using an
5713 interface from scsh. read-line and read-line! are now defined
5715 Note that the new read-line trims the terminator
5716 by default, previously it was appended to the returned string. An
5717 optional argument specifies how to process the terminator (scsh
5718 compatible). For the old behaviour: (read-line port 'concat).
5719 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
5720 returns a pair, but is converted to multiple values if the scsh
5723 socket.h: update prototypes.
5724 * socket.c (scm_recvfrom): for consistency with other procedures,
5725 take start and end as separate optional arguments.
5726 (scm_recv, scm_recvfrom): don't allow the second argument
5727 to be a size, only a buffer. Change the scheme names to
5728 recv! and recvfrom!. Don't return the buffer.
5730 * ioext.h, posix.h: move prototypes too.
5731 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
5732 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
5733 "read.h" and "unif.h".
5734 * ioext.c: include "chars.h"
5736 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
5738 * dynl.c: The dynamic linking and module registration functions
5739 are now defined even when dynamic linking is not available for the
5740 host system. Some of their functionality can be done without
5741 dynamic linking; when it's really needed, they throw errors.
5743 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
5745 * configure.in: Only define DYNAMIC_LINKING when one of the system
5746 dependent functions is detected.
5747 * dynl.c (scm_dynamic_func): New function to get the address of a
5748 function in a dynamic object.
5749 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
5750 produced by scm_dynamic_func as the thing to call.
5752 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
5754 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
5755 (scm_register_module_xxx, scm_registered_modules,
5756 scm_clear_registered_modules): New functions.
5758 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
5760 * symbols.c (scm_sysintern): Renamed to
5761 scm_sysintern_no_module_lookup.
5762 (scm_sysintern): New function to take the place of the old
5763 scm_sysintern. It uses the current toplevel lookup closure to give
5764 the symbol its value. This is a temporary hack to put packages
5765 like gtcltk into their own module.
5766 (scm_can_use_top_level_lookup_closure_var): New variable to tell
5767 us whether `scm_top_level_lookup_closure_var' has been initialized
5769 * eval.c (scm_init_eval): Set it.
5771 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5773 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
5774 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
5776 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
5778 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
5779 scm_sys_dup): deleted: FD capability will be added to other
5781 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
5782 scm_fd_free, fd_smob, scm_intern_fd.
5783 (scm_open): renamed from scm_sys_open. Return a port instead of
5784 an FD object. Make the mode argument optional.
5785 (scm_sys_create): deleted, it's just a special case of open.
5786 (scm_init_filesys): move interning of constants O_CREAT etc.,
5787 here (were previously using SCM_CONST_LONG macro).
5788 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
5790 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
5791 include "fports.h" and <stdio.h>
5792 (scm_stat, scm_select): don't support FD objects.
5794 * error.h: adjust scm_syserror_msg prototype.
5795 * error.c (scm_syserror_msg): take an extra argument for errno.
5796 Using the global value didn't always work, since it could be
5797 reset by procedure calls in the message or args arguments.
5799 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
5800 I don't understand why the check was there (and what about the
5803 * strop.c (scm_string_copy): allow shared substrings to be copied.
5805 * unif.h: corresponding change to prototypes.
5806 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
5807 recognize two new optional arguments: offset and length. Allow
5808 the port argument to be an integer (file descriptor, for scsh).
5809 Include <unistd.h> for "read" prototype.
5811 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5813 * socket.c: don't include filesys.h.
5815 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
5817 * Makefile.am: add AWK=@AWK@ (?)
5819 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
5821 Add a rule to generate errnos.c from errnos.
5822 * error.c (scm_init_error): include errnos.c.
5823 * errnos_cnvt.awk: new file, converts the list of errno codes to
5825 * errnos_get.c: new file.
5826 * errnos.default: new file, contains errnos to try if they can't
5827 be extracted from errno.h.
5828 * configure.in: if using GCC, try and extract errno codes from
5832 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
5834 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
5835 * Makefile.am: Made libguile into a libtool library.
5836 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
5837 Set libtool_libs to indicate that libguile is a libtool library.
5838 See guile/ChangeLog for details.
5839 * .cvsignore: ignore "*.lo", the libtool library objects.
5841 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5843 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
5844 use htons in getservbyport argument.
5846 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5848 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
5849 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
5852 * objprop.c (scm_object_property): No need to take the CDR of the
5853 value returned by scm_object_properties, since Aug 20 change.
5855 * configure.in: When checking for struct linger, #include
5856 <sys/types.h> as well as <sys/socket.h>. I've never known
5857 <sys/types.h> to cause any portability problems, and Solaris's
5858 <sys/socket.h> needs it.
5859 * configure: Rebuilt.
5861 I think the Sun compiler has chosen a perverse way to interpret
5862 ANSI declarations combined with K&R definitions. We'll
5863 appease it a little bit. But when it invades France, we fight.
5864 * print.c (scm_iprlist): Change 'tlr' argument to an int.
5865 * print.h (scm_iprlist): Here too.
5866 * numbers.c (scm_divbigdig): Change definition to match
5867 declaration in numbers.h.
5868 * unif.c (scm_makflo): Change definition to match declaration in
5871 * init.c (scm_boot_guile): Don't return the value of
5872 scm_boot_guile_1. This function doesn't return a value;
5873 scm_boot_guile_1 doesn't return a value (or return at all).
5875 * eval.c (unmemocopy): Add a semicolon to appease the Sun
5878 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
5879 compile. I have a feeling this function is a bad idea anyway ---
5880 one should always test for features, not systems.
5882 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
5883 semicolons. Only pure luck kept this from being noticed earlier.
5885 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
5887 * socket.c (scm_recvfrom): Added missing semicolon.
5889 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5891 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
5892 the buffer and start and end positions for scsh networking
5895 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
5897 * configure.in: Revert previous change to this file; the problem
5898 is due to transient automake weirdness.
5899 * configure: Rebuilt.
5901 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
5902 PLUGIN/guile.libs. configure generates the latter from the former.
5903 * Makefile.in: Rebuilt.
5905 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
5906 need this if we install scripts, like guile-snarf.
5907 * configure: Rebuilt.
5909 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5911 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
5913 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
5915 * socket.c (scm_addr_vector): fix faulty scm_listify.
5917 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
5919 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
5920 style block comment is no longer considered an error.
5922 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
5924 * PLUGIN/guile.libs.in: New file.
5925 * PLUGIN/guile.libs: Removed from repository.
5926 * configure.in: Create PLUGIN/guile.libs from
5927 PLUGIN/guile.libs.in. This is for including additonal libraries
5928 needed for dynamic linking.
5929 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
5930 instead of PLUGIN/guile.libs.
5932 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
5934 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
5936 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
5937 occurrences of the given element from the list, not just the
5938 first. This is how the Emacs Lisp functions behave, how the
5939 analogous Common Lisp functions behave, and (I believe) how the
5940 older Maclisp functions worked. I realize that this change may
5941 break code, but it seemed better to break it before the Guile
5944 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
5945 Their prototypes were already present in gc.h, but they weren't
5947 (scm_init_storage): Initialize scm_protects.
5948 * root.c (scm_protects): New element of scm_sys_protects.
5950 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
5952 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
5954 * libguile.h: Added #include "libguile/net_db.h".
5956 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
5957 30 change. That file is only meant for communication between the
5958 configuration process and load.c. If code linked against libguile
5959 wants to get at the paths mentioned in libpath.h, it can call
5960 functions declared in load.h.
5962 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5964 * libguile.h: Removed #include "libguile/fdsocket.h"
5966 * net_db.c: Added #include <sys/socket.h>.
5968 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
5970 * filesys.c (scm_input_waiting_p): use select in preference to
5971 FIONREAD, since the latter doesn't detect EOF.
5972 Throw error if neither select nor FIONREAD available.
5974 * socket.c (scm_connect): take a port, not a fd object.
5975 (scm_fill_sockaddr): throw an error if fam is not recognised.
5976 (scm_bind): use scm_fill_sockaddr.
5977 (scm_listen): take a port, not a fd object.
5978 (scm_accept): take and return a port. return #f in the car if
5979 address can't be got
5980 (scm_sock_fd_to_port): new procedure.
5981 (scm_socket): use scm_sock_fd_to_port.
5982 (scm_addr_vector): throw error if unrecognised address type.
5983 take an extra argument with the calling procedure name.
5984 (scm_getsockname): take a port. return #f if address can't be got.
5985 (scm_getpeername): take a port. return #f if address can't be got.
5986 (scm_recvfrom): take a port. return #f for address component if can't
5988 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
5989 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
5991 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
5993 * throw.c (scm_internal_catch): Make body funcs and handler funcs
5994 use separate data pointers, to allow them to be designed
5995 independently and reused.
5996 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
5997 Renamed from catch_body, catch_handler, and uncaught_throw; made
5999 (struct scm_catch_body_data): Renamed from catch_body_data; moved
6001 (scm_catch): Use the above.
6002 (scm_throw): Don't bother printing a message for an uncaught
6003 throw; we establish a default handler in init.
6004 * throw.h (scm_internal_catch): Prototype updated.
6005 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
6007 (struct scm_body_thunk_data): New structure, used as data
6008 argument to scm_body_thunk.
6009 * init.c (struct main_func_closure): New structure, packaging up
6010 the data to pass to the user's main function.
6011 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
6012 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
6013 scm_internal_catch to establish a catch-all handler, using
6014 scm_handle_by_message. This replaces the special-case code in
6016 (invoke_main_func): Body function for scm_internal_catch; invoke
6017 the user's main function, using the main_func_closure pointer to
6018 decide what to pass it.
6019 * root.c (struct cwdr_body_data): Remove handler_proc member.
6020 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
6021 (cwdr_handler): Removed.
6023 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6025 * socket.h (SCM_P): update bind prototype.
6026 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
6027 include "feature.h".
6028 (scm_socket): return a port, not a file descriptor object.
6029 include "fports.h" and <unistd.h>
6030 (scm_bind): take a port, not a file descriptor object.
6031 take an extra argument for address args.
6033 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
6034 INADDR_NONE, INADDR_LOOPBACK.
6036 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6038 * init.c: include net_db.h and not fdsocket.h.
6039 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
6041 * Makefile.am: corresponding changes.
6042 * socket.h: renamed from fdsocket.h, fix names.
6043 * net_db.h: renamed from socket.h, fix names.
6044 * socket.c: renamed from fdsocket.c.
6045 remove _sys from procedure names.
6046 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
6047 add "socket" to features list.
6048 * net_db.c: renamed from socket.c.
6049 remove _sys from procedure names.
6050 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
6051 add "net-db" to features list.
6052 include "net_db.h". don't include <sys/socket.h> or
6055 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6057 * tags.h (scm_tags): Removed comma at end of last enumerator.
6059 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
6061 Don't use GCC extensions to allocate space for debugging frames.
6062 (Here he goes again! Why do we put up with this?!)
6063 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
6064 an scm_debug_info structure, not an in-line array of them. Add
6065 'info' member, to say how many vect elements we've used, for eval
6067 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
6068 a new variable debug_info_end to mark the end of vect, instead of
6069 the address of the 'info' pointer itself.
6070 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
6071 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
6072 (SCM_APPLY): Explicitly allocate space for debug.vect.
6073 * debug.c (scm_m_start_stack): Same, for vframe.vect.
6074 * stacks.c: Adjusted for new debug frame structure.
6075 (RELOC_INFO, RELOC_FRAME): New macros.
6076 (stack_depth, read_frames): Use them, and new scm_debug_frame
6077 element 'info', instead of magically knowing that eval frames have
6078 an info pointer sitting after vect.
6079 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
6081 (scm_init_stacks): Formatting tweaks.
6083 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
6085 Give GCC more control flow information, so it can be sure that
6086 variables aren't used uninitialized.
6087 * error.h (scm_error, scm_syserror, scm_syserror_msg,
6088 scm_sysmissing, scm_num_overflow, scm_out_of_range,
6089 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
6090 scm_misc_error): Tell GCC that these functions never return.
6091 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
6092 out the field type, call abort if SCM_ASSERT returns, to placate
6094 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
6095 scm_wta ever returns. We can't handle this case anyway, and this
6096 gives the optimizer more information.
6097 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
6098 scm_wta ever returns.
6100 In some cases, the code is fine, but GCC isn't smart enough to
6101 figure that out; this usually happens when one variable is only
6102 initialized and used when a particular condition holds true, and
6103 we know that condition will never change within a given invocation
6104 of the function. In this case, we simply initialize the variables
6105 to placate the compiler, hopefully to a value which will cause a
6106 crash if it is ever actually used.
6107 * print.c (scm_iprin1): Initialize mw_pos.
6108 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
6109 * throw.c (scm_ithrow): Initialize dynpair.
6110 * unif.c (scm_uniform_vector_ref): Initialize cra.
6111 * struct.c (init_struct): Initialize prot.
6112 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
6114 * strports.c (scm_eval_0str): Don't return uninitialized garbage
6115 if EXPR contains no expressions.
6117 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6119 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
6120 cause an infinite loop (???). So much for the algebraic
6121 equivalency of variable-sized arrays and alloca...
6123 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
6125 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
6126 a SCM boolean, not a C boolean.
6128 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
6130 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
6131 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
6132 rules for raising scm_mtrigger. Previously, unfortunate but not
6133 unlikely circumstances could result in almost constant invokation
6134 of the gc. Now, this situations should be less likely, but they
6135 are not prevented completely.
6137 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
6139 * numbers.c (scm_fuck): Procedure removed; looks like old test
6141 * numbers.h: Prototype removed.
6143 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
6145 * debug.h (scm_debug_frame): Change `vect' member from an in-line
6146 array to a pointer, to match my Nov 21 change in eval.c.
6148 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6150 * libguile.h: Added #include "libguile/backtrace.h", #include
6151 "libguile/stacks.h".
6153 * strings.c (scm_string scm_make_string scm_string_ref
6154 scm_string_set_x scm_string_equal_p scm_string_append):
6155 Bugfix according to scm patch from Aubrey Jaffer:
6156 Corrected long-standing
6157 (not (eqv? (integer->char 128)
6158 (string-ref (make-string 1 (integer->char 128)) 0)))
6159 bug found by John Kozak <jk@noontide.demon.co.uk>.
6161 * strports.c, strports.h: Make scm_eval_0str return the value of
6162 the last expression evaluated (previously, it returned void).
6164 * strports.c, strports.h: New function: scm_read_0str. Does what
6167 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6169 * simpos.c (scm_getenv): return #f if string can't be found in the
6170 environment instead of throwing an exception, for compatibility
6171 with numerous other systems.
6173 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6175 * Makefile.am (.c.x): Use guile-snarf.
6176 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6178 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6180 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6182 * backtrace.c (scm_display_error_message): Made non-static, and
6183 renamed from display_error_message.
6184 * backtrace.h (scm_display_error_message): Added extern decl.
6185 * throw.c (uncaught_throw): Use it to display the error message.
6187 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6189 * inet_aton.c: Use #if 0, not #ifdef 0.
6191 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6193 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6194 to convert the returned value.
6195 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6196 the offset argument.
6198 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6200 Add new interface to catch/throw, usable from C as well as
6202 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6203 (scm_internal_catch): New function, replaces...
6204 (scm_catch_apply): Deleted.
6205 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6206 mechanism which is a bit more code, but can be used nicely from C
6207 and implement the Scheme semantics as well.
6208 (scm_internal_catch): This is the replacement; it's named after
6209 the analogous function in Emacs.
6210 (scm_catch): Reimplemented in terms of the above.
6211 (struct catch_body_data, catch_body, catch_handler): New
6212 functions, used by scm_catch.
6213 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6214 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6215 support for new cwdr.
6217 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6220 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6222 * acconfig.h: Added DYNAMIC_LINKING symbol.
6223 * configure.in: Add option and checks for dynamic linking.
6224 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6225 dynl.h: New files for dynamic linking support.
6226 * Makefile.am (libguile_a_SOURCES):
6228 (modinclude_HEADERS): Added "dynl.h".
6229 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
6231 * init.c (scm_boot_guile_1): Call
6232 scm_init_dynamic_linking to initialize dynamic linking support.
6234 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
6236 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
6237 (as we Schemers say). It needs to be global, so that I can tweak
6238 it for the proper operation of unexec.
6239 (scm_boot_guile_1_live): New variable, see above.
6241 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
6243 * guile-snarf.sh: Removed.
6244 * PLUGIN/guile.libs: Added dependency for -lm.
6245 * acinclude.m4: Renamed from aclocal.m4.
6246 * PLUGIN/greet: Removed.
6247 * Makefile.am, aclocal.m4: New files.
6248 * configure.in: Updated for Automake.
6250 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
6252 * eval.c (scm_definedp): Use top_level_lookup_closure_var
6253 and not top_level_lookup_thunk_var.
6255 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
6257 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
6259 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
6261 * eval.c (scm_definedp): Incompatibly changed to be a builtin
6262 Scheme function, instead of syntax. Single argument is now a
6265 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6267 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
6268 scm_ra_divide): Properly terminate statements passed as arguments
6269 to IVDEP macros. (Thanks to Bernard Urban.)
6271 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
6272 with non-constant sizes. (Thanks to Bernard Urban.)
6274 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6276 It's an "eval closure", not an "eval thunk." A thunk is a
6277 function of no arguments.
6278 * root.h (struct scm_root_state): Renamed
6279 top_level_lookup_closure_var from top_level_lookup_thunk_var.
6280 (scm_top_level_lookup_closure_var): Renamed from
6281 scm_top_level_lookup_thunk_var.
6282 * root.c (mark_root): Uses changed.
6283 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
6284 * init.c (scm_start_stack): Uses changed.
6285 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
6286 Change scheme-visible name to *top-level-lookup-closure* from
6287 *top-level-lookup-thunk*.
6289 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
6291 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
6292 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
6294 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
6296 * gc.c (struct scm_heap_seg_data): Doc fixes.
6298 * gc.c (scm_gc_sweep): Empty all segments' freelists before
6299 sweeping. Then, prepend each segment's free cells to its
6300 freelist, rather than wiping out the old value. (Thanks to Marius
6303 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6304 scm_check_freelist, scm_debug_newcell): New functions and
6305 variables, for debugging freelist problems.
6306 * pairs.h (SCM_NEWCELL): New debugging version added.
6307 * gc.h (scm_debug_newcell): Added extern declaration, used by
6308 debugging version of SCM_NEWCELL.
6310 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6312 On some systems <libc.h> conflicts with <unistd.h>, and should not
6313 be #included at all.
6314 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6315 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6316 * configure.in: Call it.
6317 * posix.c, filesys.c: Use its results to decide whether or not to
6319 * configure, scmconfig.h.in: Rebuilt with autoconf and
6322 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6324 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6325 pointer to the stdio stream before calling scm_setbuf0, so the
6326 latter will be able to retrieve it. I'm surprised this didn't
6327 segfault earlier. (Thanks to Christopher Lee.)
6329 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6331 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6334 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6336 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6337 number of stack narrowing specifier pairs. The first specifier in
6338 a pair controls inner border, the second the outer border. A
6339 number means cut that number of frames, a procedure object means
6340 cut until that object is found in operator position in a frame.
6342 * root.c (cwdr): Bugfix.
6344 * read.c: Recording of positions disabled by default.
6346 * procs.c (scm_closure_p): New function.
6348 * posix.c (scm_tmpnam): New function.
6350 * load.c: Added #include "throw.h".
6351 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6354 * load.c, load.h (scm_read_and_eval_x): New function.
6356 * eval.c: Renamed debug option "deval" to "debug".
6358 (scm_eval_x): `eval!' is no longer accessible from the scheme
6359 level. Motivation: We can't allow operations which introduce
6360 glocs into the scheme level. Guile's type system can't handle
6361 these as data. Use `eval' or `read-and-eval!' as replacement.
6363 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6364 SCM_CONSP since this is a macro!; Set vframe.prev to
6365 scm_last_debug_frame instead of 0. In this way we can look
6366 "above" the virtual start stack frame if we wish.
6367 (scm_debug_hang): New function: Useful for debugging Guile in
6368 certain tricky situations. Will probably be removed later...
6370 * debug.h: Changed semantics of debug option "backtrace". This
6371 option now only indicates whether we want automatic backtrace at
6374 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6376 * ports.c: #include "filesys.h"
6377 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
6379 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
6380 Motivation: This is system specific code which is related to file
6381 I/O. It also may use select. Added code by Gary Houston to
6382 detect presence of character in stdio buffers.
6384 * libguile.h: #include "libguile/libpath.h"
6386 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
6387 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
6388 SCM_SITE_DIR; Install libpath.h among the other include files.
6390 * load.c, load.h (scm_sys_package_data_dir): New function.
6392 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6394 * stacks.h: Bugfix: Don't use tail-array length field as stack
6395 length field! This screwed GC.
6397 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6399 * _scm.h: Added #ifndef around definition of macros min and max.
6401 * __scm.h: Added hooks for threads to plugin to in ints protection
6402 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
6403 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
6404 the main code in these macros duplicated and spread over multiple
6405 files. Renamed SCM_THREADS_SWITCHING_CODE ->
6406 SCM_THREAD_SWITCHING_CODE.
6408 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
6410 * snarf.h: New file.
6411 * guile-snarf.sh: New file.
6412 * Makefile.in (inner_h_files): Added snarf.h
6413 (ancillary, install, uninstall, distclean): Added actions for
6415 (.c.x): Use guile-snarf.
6416 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
6417 (gen_c_files): Note that these depend on guile-snarf.
6418 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
6419 now in "snarf.h". Added #include "snarf.h" to get them.
6420 * libguile.h: Added #include "snarf.h".
6421 (Patches applied and tweaked by Jim Blandy.)
6423 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6425 * socket.c: Use K&R style declaration for 'close'; the GNU coding
6426 standards suggest against providing prototypes for system
6427 functions. Thanks to Greg Troxel.
6429 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6431 * strports.c (scm_eval_0str): New function.
6432 #include "read.h", to get prototype for scm_read.
6433 * Makefile.in (strports.o): Update dependencies.
6434 * strports.h: New prototype.
6436 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
6437 scheme name from "int?" to "integer?". It seems to do the job.
6438 * numbers.h: Rename prototype too.
6439 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
6442 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
6443 scm_num_eq_p): Rename these according to R4RS conventions: call
6444 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
6445 to making libguile R4RS compliant without ice-9...
6447 * load.c (scm_sys_search_load_path): Search for files under all
6448 extensions listed in the %load-extensions variable. If FILENAME
6449 is absolute, return it unchanged, without searching the load path.
6450 (scm_loc_load_extensions): New variable, pointing to
6451 %load-extensions' value cell.
6452 (scm_init_load): Initialize it, and the value it points to.
6453 (scm_primitive_load_path): Improve error reporting.
6455 * load.c (scm_loc_load_hook): New variable, pointing to value cell
6456 of new Scheme variable %load-hook.
6457 (scm_primitive_load): Apply %load-hook to filename.
6459 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
6461 * configure.in: add tests for figuring out whether buffered data
6462 is available in a FILE structure, which is needed by char-ready.
6464 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
6467 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
6468 exceptions using misc_error instead of syserror. It seems a bit
6469 odd to throw an exception if a string can't be found in the
6470 environment, but it's consistent with open-file, stat etc.
6471 (simpos.h): remove sys_ from getenv.
6473 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
6474 occurs, throw an error instead of returning errno. Return value
6476 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
6478 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
6480 * filesys.c (scm_stat2scm): derive file type and permissions from
6481 the stat mode and append them to the returned vector.
6482 There isn't much overhead in doing this and it avoids the need to
6483 work with S_IRUSR et al. in Scheme.
6484 Define symbols scm_sym_regular etc.
6485 (scm_init_filesys): don't intern S_IRUSR etc.
6487 * load.c: change s_try_load and s_try_load_path to s_primitive_load
6488 and s_primitive_load_path.
6490 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
6492 * error.h: don't declare error symbols. prototype for scm_misc_error.
6494 * stackchk.c (scm_stack_overflow_key): defined here instead of in
6497 * error.c: use SCM_SYMBOL to set up error keys.
6498 scm_misc_error: new procedure.
6500 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
6502 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
6503 between `#!' and `!#' is ignored.
6504 (skip_scsh_block_comment): New function.
6506 * feature.c (scm_set_program_arguments): New argument, FIRST.
6507 * feature.h: Update prototype.
6508 * init.c (scm_boot_guile_1): Pass new argument to
6509 scm_set_program_arguments.
6511 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6513 * init.c (scm_start_stack): Don't initialize scm_progargs here.
6514 (scm_boot_guile): Call scm_set_program_arguments here, later than
6515 the old initialization.
6517 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
6518 initialization procedure.
6519 - Delete in, out, err arguments; there are other perfectly good
6520 ways to override these when desired.
6521 - Delete result argument; this function shouldn't ever return.
6522 - Rename init_func argument to main_func, for less confusion.
6523 - Delete boot_cmd argument; main_func is more general.
6524 -Add 'closure' argument, to help people pass data to main_func
6525 without resorting to global variables.
6526 - Abort if reentered; don't bother returning an error code.
6527 - Call scm_init_standard_ports to set up the default/current
6528 standard ports; no need to pass them to scm_start_stack.
6529 - Remove code to evaluate the boot_cmd, and start the repl; let
6530 the user do something like that in main_func if they want.
6531 - Remove code to package up a return value; main_func can do any
6533 - Call exit (0), instead of returning.
6534 (scm_start_stack): Don't initialize the I/O ports here; that's
6535 weird. Delete in, out, err arguments. Move guts to
6536 scm_init_standard_ports, scm_stdio_to_port.
6537 (scm_init_standard_ports): New function, to set up current and
6538 default standard ports.
6539 (scm_start_stack, scm_restart_stack): Make these static.
6540 * init.h (scm_boot_guile): Adjust declaration.
6541 (scm_start_stack, scm_restart_stack): Remove externally
6542 visible declarations for these.
6543 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
6545 * fports.c (scm_stdio_to_port): New function. Its guts used to be
6546 written out several times in scm_start_stack.
6547 * fports.h: New declaration for the above.
6549 * feature.c (scm_set_program_arguments): New function.
6550 * feature.h: New declaration for the above.
6552 * ports.c: Formatting tweak.
6554 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
6556 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
6557 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
6558 for obtaining the address of a car or cdr field. Motivation:
6559 &SCM_CXR make assumptions about the internal structure of the
6562 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
6563 Motivation: see SCM_CXRLOC.
6565 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
6566 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
6567 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
6568 Motivation: Safer use. Some other macros are defined in terms of
6569 these operations. If these are defined using the SCM_SETCXR
6570 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
6571 to inefficiency and an <e1> with side-effects could potentially
6572 break. Also, these particular operations are heavily utilized in
6573 the garbage collector. In unoptimized code there will be a
6576 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
6577 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
6578 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
6579 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
6580 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
6581 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
6582 vports.c: Cleaned up use of pairs: Don't make any special
6583 assumptions about the internal structure of selectors and
6584 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
6585 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
6586 (Among other things, this change makes it easier to build Guile
6587 with certain compilers which have problems with casted lvalues.)
6589 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6591 * stacks.c: Improve selection of relevant stack frames when making
6592 a stack object. Introduce one level of indirection in the stack
6593 object to make it possible to "narrow" to a certain region of the
6594 stack. This facilitates making use of more clever algorithms (not
6595 implemented) for selecting relevant frames and gives a cleaner
6596 design since selection of frames can be done independently of
6597 extraction of frames from the real stack.
6598 (scm_stack_id): Also take #t as argument which means look at
6601 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
6602 Turn n_tail into an integer directly representing current number
6603 of frames in stack. Add field tail.
6605 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
6607 * debug.c (scm_make_memoized): Made it available at scheme level.
6608 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
6609 SCM_NIMP before applying heavier predicates in argument checking.
6610 (scm_local_eval): Also take memoized object as argument.
6612 * backtrace.c (scm_display_error): Just a safety measure: Stacks
6613 aren't created with zero length, but should such a strange
6614 creature suddenly turn up...
6616 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
6618 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
6619 `del', for the sake of C++ compilers. (Patch applied by JimB.)
6621 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
6623 * variable.c (scm_make_variable): Make the name hint optional, as
6625 (anonymous_variable_sym): Renamed from variable_sym. All uses
6628 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
6629 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
6630 of scm_primitive_load_path was also changed to
6631 "primitive-load-path", from "%try-load-path". Callers changed.
6632 We'd like to respect the convention that a function named
6633 "try-mumble" should behave just like the function called "mumble",
6634 but return #f instead of signalling some error.
6635 * load.h: Rename prototypes.
6637 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6639 * print.c (make_print_state, grow_print_state), print.h: Modified
6640 the print state representation: Don't use a tail array for
6641 recording of circular references. Resizing of the print state
6642 structure invalidates the print state pointer. To avoid passing
6643 around an indirect print state reference to all printing
6644 functions, we instead let the print state reference a resizable
6647 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
6649 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
6650 Don't crash when passed an improper list terminated by a
6651 non-immediate value.
6653 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
6655 Allocate data for structures on an eight-byte boundary, as
6656 required by the tagging system.
6657 * struct.c (alloc_struct): New function.
6658 (scm_make_struct, scm_make_vtable_vtable): Call it.
6659 * struct.h (scm_struct_n_extra_words): Bump to 3.
6660 (scm_struct_i_ptr): New "field".
6661 * gc.c (scm_gc_sweep): When we need to free the data, use the
6662 information stored by alloc_struct to find the beginning of the
6663 block allocated to the structure, so we can free it.
6665 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6667 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
6670 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
6671 (scm_debug_info): New member: id.
6673 * stacks.c: Stacks are now represented as structs; Stacks have an
6674 id given to them by `start-stack'.
6675 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
6677 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
6678 Changed stack representation.
6680 * debug.c (scm_procedure_name): Try procedure property `name' for
6681 compiled closures aswell.
6683 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
6685 * eval.c: scm_i_name moved to gsubr.c
6686 (scm_m_define): Record names of all kinds of procedure
6687 objects. (Earlier, only closures were recorded.)
6689 * procprop.h: Added declaration of scm_i_name.
6691 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
6692 (scm_make_gsubr): Record names of compiled closures.
6694 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6696 * debug.c, debug.h: Removed obsolete code.
6698 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
6699 stacks.c: Renamed regs --> scm_contregs.
6701 * print.c (scm_free_print_state): Cleanup print state before
6702 returning it to pool. It is better to do it here than in
6703 scm_prin1 since scm_prin1 is called often.
6705 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
6706 s_set_source_property_x): Check that first argument is a pair or a
6709 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
6710 scm_i_line, scm_i_column and scm_i_breakpoint global.
6712 * init.c: Added #include "backtrace.h" and #include "stacks.h".
6713 (scm_boot_guile_1): Added calls to scm_init_backtrace and
6716 * debug.h: Added debug object smob declaration and macro
6719 * configure.in: Build with backtrace.o and stacks.o if debug
6722 * Makefile.in: Added entries for new files: backtrace.c,
6723 backtrace.h, stacks.c and stacks.h.
6725 * symbols.c (scm_sym2ovcell): Fixed documentation.
6727 * _scm.h (min, max): Added.
6729 * async.c: Moved `min' macro to _scm.h.
6731 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
6732 SCM_BACKTRACE_INDENT.
6734 * eval.c: Added new debug options `maxdepth' and `indent'.
6736 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
6738 * print.h: Added selector SCM_PRINT_STATE.
6740 * print.c: New functions: scm_make_print_state,
6741 scm_free_print_state.
6743 * print.h: Added declarations for scm_make_print_state,
6744 scm_free_print_state.
6746 * debug.c (scm_m_start_stack): New acro.
6748 * debug.h: Small cleanup.
6750 * init.c (scm_boot_guile_1): Moved scm_init_debug below
6753 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

6778 More prototype-related changes from Marius Vollmer:
6779 * gdb_interface.h: Wrapped header file in #ifdef/#endif
6780 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
6781 * ports.h (ptobfuns): Added prototypes. This means some casting in
6783 * fports.c: Added casts for initializations, since the functions
6784 are defined to take FILE * as their stream argument, not SCM.
6785 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
6786 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
6787 to `char *str_data' to conform to prototype.
6789 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
6791 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
6793 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
6795 * stime.c, stime.h: use SCM_P method.
6797 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
6799 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
6800 be given at least two arguments. Insist that lst's last element
6801 be a list, but don't make any requirements of its predecessors.
6803 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
6805 * eval.c (scm_nconc2last): Revert last change; there seems to be
6806 other stuff going on here.
6808 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
6810 * eval.c (scm_nconc2last): Make sure that each element of lst
6811 (which is a list of argument lists, except for the tail) is a
6812 proper list, i.e., finite and terminated by '().
6814 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6816 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
6819 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
6820 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
6823 * vectors.c (scm_make_vector): Fill vectors with the undefined
6824 value, to help make Guile Scheme code more portable to other
6827 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
6828 * symbols.h, tags.h: Doc fixes.
6830 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
6832 * async.c (scm_take_signal): Doc fixes.
6834 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
6836 * numbers.c (scm_divbigint): When the remainder is zero, we don't
6837 want to subtract it from the modulus; we just want to leave it
6840 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
6842 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
6845 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
6847 * throw.c (scm_catch_apply): Finished implementation of
6850 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
6852 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
6854 (scm_init_filesys): set "i/o-extensions" feature.
6857 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
6859 * Makefile.in (root.o): Correct dependencies.
6861 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
6863 * Makefile.in: Added dependency entry for root.o.
6865 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
6866 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
6868 * init.c (scm_start_stack): Set initial root continuation number
6871 * procs.c: New function: scm_thunk_p.
6873 * procs.h: Added declarations of scm_thunk_p.
6875 * root.c: Renamed `call-with-new-root' -->
6876 `call-with-dynamic-root'.
6877 (cwdr): Removed allocation of new root state. This should be done
6878 separately by use of scm_make_root.
6879 (scm_apply_with_dynamic_root): New function: Does what it
6880 sounds like. Needed when spawning threads.
6882 * root.h: Added member last_debug_frame to root state.
6883 Added #include "libguile/debug.h"
6885 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
6886 arguments. The motivation is that code in root.c needs catch
6887 functionality, and we want to avoid code duplication.
6888 New functions: scm_catch, scm_lazy_catch. These are wrappers for
6889 scm_catch_apply. scm_lazy_catch is intended to introduce catch
6890 handlers that run without popping the stack into the dynwind
6893 * throw.h: Added prototypes for scm_catch_apply and
6896 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6898 * root.h (scm_root, scm_set_root): Decouple thread support details
6899 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
6900 SCM_SET_THREAD_LOCAL_DATA.
6902 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
6903 and tortoise scanning loop.
6905 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
6907 * Makefile.in: Rebuild dependencies.
6909 * libguile.h: #include "libguile/print.h" before "smob.h", since
6910 the latter uses the print_state structure.
6912 * throw.c (scm_ithrow): Use the correct variable when checking to
6913 see if a given element of scm_dynwinds is a valid catch.
6915 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
6916 structure, abort; don't just silently ignore the garbage.
6918 * _scm.h: #include "print.h" here, since it seems to be used just
6920 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
6921 strports.c, unif.h: Don't #include "print.h".
6923 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6925 * feature.h (scm_loc_features): Removed external declaration.
6926 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
6928 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6930 * feature.c (scm_init_feature): Added threads feature (needs to be
6931 initialized here, since features doesn't exist when
6932 scm_init_threads is called).
6934 * libguile.h: Added #include "libguile/../threads/threads.h".
6935 (This is a kludge to get thread support working. This should be
6938 * configure.in, acconfig.h: Added flags for thread support.
6940 * scmsigs.c: Define `signal' to be `pthread_signal' if using
6943 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
6944 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
6947 * _scm.h: Added conditional #include "threads.h"
6949 * __scm.h (SCM_ASYNC_TICK): Added call to macro
6950 SCM_THREADS_SWITCHING_CODE.
6952 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
6953 allocate the basic dynamic root object.
6954 (scm_boot_guile): Added call to scm_init_root.
6956 * root.c, root.h: Added root smob.
6957 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
6958 functions: Implements dynamic roots mostly according to spec in
6959 SCM manual. Main difference is that the second argument is a
6960 throw handler rather than an error "thunk".
6962 * root.h: Added declaration of scm_init_root.
6964 * root.c: Added #include "genio.h", #include "smob.h", #include
6965 "pairs.h", #include "throw.h", #include "dynwind.h", #include
6967 (scm_init_root): Added #include "root.x".
6969 * throw.c: Added #include "stackchk.h"
6970 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
6971 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
6972 can be used in scm_call_with_new_root; Added reenabling of stack
6973 checking when catching a throw.
6975 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
6977 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
6979 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
6980 element is not found, as per R4RS.
6982 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
6984 * list.c: Doc fixes throughout.
6986 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6988 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
6989 declare the char * to be const. Avoids a warning in rgx.c.
6991 * ports.h: spelling fix.
6993 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
6996 * load.c (scm_sys_try_load_path): throw an error if file not found
6997 (like it says it in NEWS).
6999 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7001 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
7002 PROPS slot to '(), not #f; it's an empty alist.
7004 * throw.h, throw.c: Use SCM_P instead of #if hair.
7006 Remove special support for uncaught throws; see throw.c for
7008 * throw.c (uncaught_throw): New function.
7009 (scm_ithrow): Call uncaught_throw if we don't find a throw
7010 target; don't mess with scm_bad_throw_vcell.
7011 (scm_bad_throw_vcell): Variable deleted.
7012 (scm_init_throw): Don't initialize it.
7014 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
7017 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7019 * numbers.c (scm_istr2int): If the number is short (as most
7020 numbers are), just call scm_small_istr2int to deal with it.
7021 (scm_small_istr2int): New function, created by un-#ifdefing the
7022 non-bignum version of scm_istr2int and renaming it.
7024 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
7026 * load.c (scm_sys_try_load): don't check whether value returned
7027 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
7028 Change the Scheme name from %try-load to primitive-load.
7030 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
7031 Can avoid passing a message, allowing it to be derived in the
7032 error handler (e.g., if we want to throw to the key both from
7035 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
7037 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
7038 references now have a new appearance which is more compact and
7039 also gives a clue about what the target of the reference is.
7040 By setting parameters in the print state, more fancy printing can
7041 be achieved. This is used by the (not yet commited) backtrace
7044 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
7046 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
7049 * print.c: Added #include "struct.h". Removed function
7052 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
7053 scm_iprin1. Removed prototype for scm_prlist.
7055 * arbiters.c (prinarb),
7056 async.c (print_async),
7057 debug.c (prindebugobj, prinmemoized),
7058 eval.c (prinprom, prinmacro),
7059 filesys.c (scm_fd_print, scm_dir_print),
7061 mallocs.c (prinmalloc),
7062 numbers.c, numbers.h (scm_floprint, scm_bigprint),
7063 smob.h (scm_smobfuns),
7064 srcprop.c (prinsrcprops),
7066 unif.c, unif.h (scm_raprin1, rapr1),
7067 variable.c (prin_var): Changed argument `int writing' to
7068 `scm_print_state *pstate'.
7070 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
7071 that it will be called before scm_init_print.
7073 * print.c (scm_prin1): Print states are now allocated when calling
7074 scm_prin1 and then passed around to all printing functions as an
7075 argument. A cache `print_state_pool' enables reuse of print
7077 (scm_make_print_state): New function.
7078 (scm_iprin1): Adaption to print states.
7079 (scm_iprlist): An initial "hare and tortoise" scan brings down
7080 time complexity to O (depth * N). (Better time complexity will be
7081 achieved when the printing code is completely rewritten.)
7083 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7085 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
7086 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
7087 it gets done whether or not the cache variable has a value.
7089 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7091 Distinguish #f and ().
7092 * __scm.h: #undef SICP.
7093 * pairs.h (SCM_EOL): Delete this definition, equating it with
7095 * tags.h (SCM_EOL): Give it a new definition here; I think I found
7096 the value it used to have. Doc fixes, too.
7098 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
7100 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
7101 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
7102 Lord's implementation of structs, allowing for tail arrays as
7103 described in the manual. Also fixed some bugs. (Both the interface
7104 and the implementation should be improved.)
7106 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
7108 * print.c, print.h: Closures now print like #<procedure foo (x)>.
7109 People who whish to see the source can do `(print-enable 'source)'.
7110 Removed #ifdef DEBUG_EXTENSIONS.
7112 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7114 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
7115 integer (assuming for now accepting an integer is a good thing).
7117 * error.c, fports.c: replace use of %S in lgh_error args with %s.
7118 %S will be used instead for write'ing arguments.
7120 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
7121 asserts. fix a few other asserts.
7122 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
7123 scm_uniform_vector_ref, scm_array_set_x,
7124 scm_dimensions_to_unform_array): change args in
7125 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
7126 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
7127 scm_substring_fill_x): likewise.
7128 gsubr.c (scm_gsubr_apply): likewise.
7129 eval.c (SCM_APPLY): likewise.
7131 * eval.c (4 places): replace scm_everr with lgh_error or
7134 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
7135 scm_memory_error): new procedures.
7136 scm_everr: deleted. can use scm_wta, dropping first two args.
7137 scm_error: convert NULL subr to SCM_BOOL_F.
7139 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
7142 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
7145 * error.c, error.h: new error keys: scm_arg_type_key,
7146 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
7148 scm_wta: reimplement using lgh_error instead of scm_everr.
7150 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
7152 * gdbint.c: scm_lread now has one more argument.
7154 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
7155 scm_port_\1; Added mutator scm_set_port_filename_x (used when
7156 loading source from non-file ports, which, e. g., happens when
7157 using the Emacs interface).
7159 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
7162 * read.c: Added code for recording of positions of source code
7163 expressions; New functions: recsexpr, scm_lreadrecparen;
7164 _scm_make_srcprops --> scm_make_srcprops
7165 (scm_flush_ws): Removed updating of positions counters. This work
7166 is already done by scm_gen_getc
7168 * read.h: Added prototype for scm_lreadrecparen
7170 * print.c: Added #include "alist.h"
7172 * eval.c: Added #include "hash.h"
7174 * eq.c: Added #include "ramap.h"
7176 * options.c: Documentation fixes.

7180 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7181 --> scm_make_srcprops
7183 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7184 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7185 function calls in the definition of the whash access macros.
7187 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7189 * init.c (scm_boot_guile): Add level of indirection to
7190 scm_boot_guile_1() to ensure that stack base pointer is properly
7191 initialized. There was no guarantee that variable i was the
7192 highest/lowest variable on stack (i.e. the call frame of
7193 scm_boot_guile was not completely protected from gc).
7195 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7197 * ports.h (scm_port_table): put back file_name, it will be used to
7198 support debugging. Undo related changes in fports.c, ioext.c,
7201 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7203 * ports.h (scm_port_table): remove file_name member for now, it seems
7205 * fports.c (scm_open_file): don't set file_name in PTAB.
7206 (prinfport): don't use file_name in PTAB.
7207 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7208 * ports.c (scm_add_to_port_table): don't intialize file_name.
7209 (scm_port_file_name): remove for now.
7210 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7212 * fports.h (scm_mkfile): prototype deleted.
7213 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7215 * debug.c, unif.c: use scm_out_of_range instead of
7216 wta for range errors (ASSERT still needs work).
7218 * error.c, error.h (scm_out_of_range): new procedure.
7220 * error.c, error.h (scm_out_of_range_key): new key.
7222 * posix.c (scm_sync): #else was missing.
7224 * error.c, error.h: append _key to names scm_num_overflow and
7227 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
7228 of consing an empty list.
7229 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
7230 of macros, saves code and string space.
7231 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
7232 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
7233 lower case. Rename scm_syserror_m to scm_syserror_msg.
7234 error.h: prototypes for new procedures.
7236 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
7238 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
7240 * error.c, error.h: setup scm_num_overflow key.
7242 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
7243 Remove definition of SCM_OVSCM_FLOW.
7245 * fports.c (scm_open_file): use SCM_SYSERROR_M.
7247 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
7248 explicit message and args.
7250 * error.c, error.h, __scm.h: change system_error_sym to
7253 * error.c (system_error_sym): remove leading %% from the Scheme name
7256 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
7258 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7260 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
7261 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
7262 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
7263 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
7264 renamed. (These were introduced by unsupervised name
7267 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7269 * print.c: Added code for detection of circular references during
7270 printing. (init_ref_stack, grow_ref_stack): New functions. Added
7271 a hook for printing of closures (accessible via print options).
7272 This leads to a split of calls to scm_iprin1 into two classes:
7273 elementary print operations (e. g. the code which prints a smob)
7274 still use scm_iprin1 while top level calls (like scm_display) use
7275 scm_prin1. scm_prin1 begins by clearing the data structure used
7276 to record reference information.
7278 * print.h: Added declarations of scm_prin1 and scm_prlist.
7280 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
7282 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
7284 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
7286 * error.c (err_head): scm_iprin1 --> scm_prin1
7288 * debug.c: Adjusted header comment.
7292 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7294 * strerror.c: Doc fix.
7296 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7298 * gdbint.c (gdb_read): Now possible to run during GC.
7299 (unmark_port, remark_port): New functions.
7301 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7303 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7304 of allocating a new string object. Also, increase size by
7305 the factor 2 instead of 1.5.
7307 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7309 * __scm.h (SCM_P): Corrected to run under traditional C.
7311 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7314 * async.c: Calls to scm_sysintern corrected.
7316 * async.h (scm_async_clock): Redundant declaration removed.
7318 * continuations.c (scm_dynthrow): Redundant declaration removed.
7320 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
7321 Definition typos corrected.
7323 * debug.h: Missing declarations of functions in debug.c added
7326 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7327 Missing declarations to functions in eval.c added.
7329 * filesys.c: Possibly uninitialized variable rv.
7331 * gc.h (scm_object_addr, scm_unhash_name): Missing
7332 declarations of functions defined in gc.c added.
7334 * genio.c: Possible typos str_data -> wstr_data. ???
7336 * genio.c: Possibly unintended shadowing of local variable
7337 `int c' (gotos out of scope of inner `c'). ???
7339 * init.c: Uninitialized `SCM last' may be used.
7341 * ioext.h: (scm_sys_isatty_p): Typo.
7343 * list.h (scm_list_head): Missing prototype for function in
7346 * numbers.c (scm_two_doubles): Changed from extern to static
7347 (is used only within numbers.c).
7349 * numbers.h: Repeated declarations removed.
7351 * ports.h (scm_close_all_ports_except): Declaration for the
7352 function defined in ports.c added.
7354 * posix.h: Missing declarations added.
7356 * procs.h (scm_make_subr_opt): Missing declaration added.
7358 * socket.h (scm_sys_gethost): Missing declaration added.
7360 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7362 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7363 Missing declarations added.
7365 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
7367 * struct.c: Uninitialized variable `SCM answer' may be used.
7369 * unif.c (l2ra): Declaration prototype.
7371 * unif.c (scm_array_equal_p): Dummy definition removed (it is
7372 defined in ramap.c).
7374 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
7375 Redundant declarations removed (they are in ramap.h).
7377 * variable.h (scm_make_udvariable,
7378 scm_make_undefined_variable): Declaration corrected to
7379 correspond variable.c.
7381 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
7382 Missing declarations added.
7384 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
7386 * Makefile.in (distclean): Don't forget to delete fd.h.
7388 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7390 * fd.h.in, tags.h: Trivial cleanups.
7392 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
7393 marksweep.h just declared functions from gc.c.
7394 * gc.h, libguile.h: Don't #include "marksweep.h".
7395 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7396 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
7397 dependencies updated.
7399 * libguile.h: Don't #include "files.h"; it's been deleted.
7401 * files.c (scm_sys_delete_file): Moved to filesys.c.
7402 File is now empty; deleted.
7404 * filesys.c: scm_sys_delete_file is now here. Remove
7405 #if's; they seem to rely on remnants of an old portability
7406 regimen. If the problems come up again, solve them properly,
7407 using autoconf. Specifically: Don't test M_SYSV, and #define
7408 remove to be unlink if it's #defined; don't use remove just
7409 because HAVE_STDC_HEADERS is #defined.
7410 * filesys.h: Add declarations for scm_sys_delete_file.
7411 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7412 files.o, files.h, files.c, and files.x.
7413 * init.c: Don't #include "files.h", and don't call scm_init_files.
7415 Use SCM_P instead of PROTO; the latter intrudes on the user's
7417 * params.h: Deleted; definition of SCM_P moved to...
7418 * __scm.h: ... here, where it replaces PROTO macro.
7419 * libguile.h, smob.h: Don't #include "params.h".
7420 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
7421 smob.h: Fix prototypes accordingly.
7422 * Makefile.in: Update dependencies.
7423 (inner_h_files): Remove params.h.
7425 * gc.c: #include "gc.h"; every module should include its header,
7426 to let the compiler cross-check the declarations against the
7429 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
7430 simpos.h: #include "libguile/__scm.h".
7432 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
7434 * init.c: Don't forget to #include smob.h and init.h.
7435 * Makefile.in: Dependencies updated.
7437 * smob.h: Use PROTO instead of #if __STDC__.
7439 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
7441 * __scm.h: Doc fixes.
7443 * __scm.h, libguile.h: Use "quotes" in the #includes, not
7444 <angles>; this allows `make depends' to work properly.
7446 * libguile.h: #include smob.h and pairs.h before the others; they
7447 define typedefs used by other headers.
7449 C files should #include only the header files they need, not
7450 libguile.h (which #includes all the header files); the pointless
7451 recompilation was wasting my time.
7452 * Makefile.in (all .o dependency lists): Regenerated.
7453 * libguile.h: Don't try to get a definition for size_t here...
7454 * __scm.h: Do it here.
7455 * _scm.h: Since this is the internal libguile header, put things
7456 here that all (or a majority) of the libguile files will want.
7457 Don't #include <libguile.h> here; that generates dependencies on
7458 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
7459 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",

7557 * weaks.c: Get "weaks.h".
7559 * stackchk.h: #include "libguile/debug.h",
7561 * print.h, read.h: #include "options.h", since everyone who uses
7562 either of these files will need that.
7564 * smob.h: #include "ports.h", "genio.h", and "print.h", since
7565 anyone who uses this file will need them to define the smob
7566 printing functions. Also, get markers.h, since people will need
7567 to #define the mark functions.
7569 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
7570 * ports.h: ... to here.
7572 * ports.h (scm_port_table_size): Explicitly give type as 'int';
7573 don't rely on archaic C default type rules.
7575 * fports.h: #include "libguile/ports.h", since you need that in
7576 order to parse this.
7578 * genio.h: #include "libguile/print.h", because you need that to
7579 parse this; don't bother #including "ports.h", since print.h gets
7582 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
7584 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
7585 this; it's now a reference to an element of *scm_root.
7587 * debug.h: Don't #include "options.h"; the compiler won't be able
7588 to find that once the headers are installed; instead, #include
7589 "libguile/options.h".
7590 * gc.h: Same, with marksweep.h.
7591 * mbstrings.h: Same, with symbols.h.
7592 * scmhob.h: Same, with _scm.h.
7593 * smob.h: Same, with params.h.
7595 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
7596 C files; there's no need for this, and it forces recompilations
7599 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
7601 * error.c (scm_error): declare scm_error_callback.
7603 * error.h: prototype for scm_error_callback.
7605 * __scm.h: define lgh_error.
7606 (SCM_SYSERROR): redefine using lgh_error.
7608 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
7610 * error.c (scm_error): new procedure.
7612 * error.h: prototype for scm_error.
7614 * Makefile.in (install): install scmconfig.h from the current
7615 directory, not $(srcdir).
7617 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7619 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7620 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7621 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

7627 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7628 vports.h, weaks.h: #include "libguile/__scm.h", not
7629 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
7630 dependencies are within libguile properly.
7632 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7634 * Makefile.in (.c.x): Simplify; there's no need to run this rule
7635 when scmconfig.h doesn't exist.
7637 * load.c (scm_sys_try_load): Correct spelling.
7639 * feature.c (scm_loc_features): Make this static.
7641 * Makefile.in (libpath.h): Omit trailing slash from path. We
7642 shouldn't require it of users, so why put it here?
7644 Move code to initialize and search %load-path from ice-9 to C
7645 code, so we can use the load-path to find the ice-9 boot code;
7646 this makes it easier to run Guile without installing it. See
7647 corresponding changes in guile/Makefile.in.
7648 * feature.c: Move stuff concerned with the load path to load.c.
7649 (scm_compiled_library_path): Deleted.
7650 Don't #include libpath.h here.
7651 * feature.h: Don't mention scm_compiled_library_path.
7652 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
7653 <sys/stat.h>, and <unistd.h> (if present).
7654 (R_OK): #define if the system hasn't deigned to.
7655 (scm_loc_load_path): New variable.
7656 (scm_init_load_path, scm_sys_search_load_path,
7657 scm_sys_try_load_path): New functions.
7658 (scm_init_load): Initialize scm_loc_load_path to point to the
7659 value cell of the Scheme %load-path variable.
7660 * load.h: Add declarations for scm_sys_search_load_path,
7661 scm_sys_try_load_path.
7662 * init.c: Call scm_init_load_path.
7663 * Makefile.in (feature.o, load.o): Dependencies updated.
7665 * load.c, load.h: Rewrite using PROTO macro.
7667 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7669 * gc.c (scm_cellp): New function: C predicate to determine if an
7670 SCM value can be regarded as a pointer to a cell on the heap.
7672 * gc.h: Added declaration of scm_cellp.
7674 * gdb_interface.h: New file: The GDB interface header from the GDB
7677 * gdbint.c: New file: GDB interface.
7679 * gdbint.h: New file: GDB interface.
7681 * libguile.h: Added #include <libguile/gdbint.h>.
7683 * init.c (scm_boot_guile): Added scm_init_gdbint.
7685 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
7686 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
7687 found if object files and source are kept separate).
7689 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
7691 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
7693 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
7695 * configure.in: Don't substitute the values of TCL_SRC_DIR and
7696 TK_SRC_DIR; they're not relevant any more.
7698 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
7699 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
7701 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
7703 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
7704 search path, so we can find the <libguile/MUMBLE.h> headers.
7706 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
7708 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
7709 implicit in the .c.o rule.
7710 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
7713 Put the library path in a header file, instead of passing it on
7714 the command line in every compilation.
7715 * Makefile.in (libpath.h): New target.
7716 (feature.o): Depend on libpath.h.
7717 (clean): Delete libpath.h.
7718 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
7719 * feature.c: ... #include "libpath.h" here.
7720 * .cvsignore: Ignore libpath.h.
7722 Don't install the unwashed masses of Guile header files in the
7723 main #include path; put most of them in a subdirectory called
7724 'libguile'. This avoids naming conflicts between Guile header
7725 files and system header files (of which there were a few).
7726 * Makefile.in (pkgincludedir): Deleted.
7727 (innerincludedir): New variable; this and $(includedir) are enough.
7728 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
7729 (installed_h_files): Divide this up. Now this variable lists
7730 those header files which should go into $(includedir) (i.e. appear
7731 directly in the #include path), and ...
7732 (inner_h_files): ... this new variable says which files appear in
7733 a subdirectory, and are referred to as <libguile/mumble.h>.
7734 (h_files): List them both.
7735 (install): Create innerincludedir, not pkgincludedir. Put
7736 the installed_h_files and inner_h_files in their proper places.
7737 (uninstall): Corresponding changes.
7738 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7739 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,

7746 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7747 vports.h, weaks.h: Find __scm.h in its new location.
7748 * __scm.h: Find scmconfig.h and tags.h in their new locations
7749 (they're both "inner" files).
7751 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
7753 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
7755 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7757 * posix.c: Doc fixes.
7759 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
7761 * socket.c: Don't include a prototype for inet_aton; just use a
7762 K&R style declaration, to avoid warnings but minimize the chance
7763 of conflicts with the system.
7765 On NextStep, <utime.h> doesn't define struct utime, unless we
7766 #define _POSIX_SOURCE before #including it.
7767 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
7768 * acconfig.h: New comment text for above CPP symbol.
7769 * configure.in: Call it.
7770 * posix.c: #define _POSIX_SOURCE if it seems necessary.
7772 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
7774 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
7775 testing for __EMX__.
7777 * posix.c: #include <libc.h>, if it exists.
7779 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
7780 don't even know if the latter exists.
7782 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
7783 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
7784 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
7786 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
7788 (scm_init_posix): Use them when initializing the Scheme constants
7791 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
7793 * Makefile.in (libdir, includedir, bindir): Use the
7794 autoconf-supplied values, instead of deriving them ourselves.
7795 (pkgincludedir, datadir, pkgdatadir): New variables.
7796 (install, uninstall): Put the header files in a special
7797 subdirectory, not in the main search path.
7799 * Makefile.in (ALL_CFLAGS): Provide the proper value for
7800 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
7802 * Makefile.in (IMPLPATH): Deleted; never used.
7804 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
7805 on the Tcl/Tk source any more.
7806 (INCLUDE_CFLAGS): Remove references to the above.
7808 * Makefile.in (version.o): Corrected dependencies.
7810 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
7812 * libguile.h: #include "version.h"
7814 * init.c (scm_boot_guile): Call scm_init_version.
7815 * gscm.c (gscm_run_scm): Call scm_init_version.
7817 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
7818 GUILE_VERSION): AC_DEFINE these.
7819 (acconfig.h): #undef the above symbols.
7821 * Makefile.in (libobjs): Add version.o.
7822 (installed_h_files): Add version.h.
7823 (c_files): Add version.c.
7824 (gen_c_files): Add version.x.
7825 (version.o): New rule.
7826 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
7827 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
7828 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
7829 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
7830 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
7831 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
7832 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
7833 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
7834 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
7835 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
7836 weaks.o): Add version.h to dependency lists.
7837 (markers.o): Remove duplicate rule.
7839 * version.h: New file.
7841 * version.c: New file.
7843 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7845 * symbols.c (scm_strhash): scm_downcase is now a function, not an
7846 array; use it appropriately. Since GCC is quite happy to
7847 subscript functions, it never warned us about this; we should use
7848 -Wpointer-arith in the future. I guess we never tested
7851 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
7853 * socket.c: Doc and copyright fixes.
7855 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7857 * debug.c: Fixed and improved gdb support.
7859 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7861 * socket.c: Added declaration of inet_aton to avoid compiler
7862 warning. (Hope this solution is correct.)
7864 * stime.c: Added declaration of ftime. (This is missing in
7867 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
7869 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
7871 * Makefile.in (c_files): add strerror.c.
7873 * strerror.c: new file from Emacs' sysdep.c.
7874 maybe configure should also check for sys_errlist.
7876 * configure.in (AC_REPLACE_FUNCS): add strerror.
7878 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7880 * debug.c (scm_init_debug): Added initialization for
7881 scm_evaluator_traps.
7883 * debug.h, debug.c: Various name changes.
7884 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
7885 "debug-options-interface". See commentary in options.c.
7887 * options.h, options.c: Options now have documentation strings.
7888 Also added a long explanatory commentary.
7890 * eval.c, print.h, print.c, read.h, read.c: Modifications to
7893 * gscm.c, init.c, root.c, throw.c: Bug fixes:
7894 last_debug_info_frame is now updated in all cases.
7896 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
7899 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7901 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
7902 Added option STACK_CHECKING.
7904 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7906 * Makefile.in: Added {debug,options,srcprop}.{h,c}
7908 * __scm.h: Removed symbols for debugging support.
7910 * acconfig.h: Added symbols for debugging support.
7912 * configure.in: Added user option for debugging support.
7913 --enable-debug will include the debugging code into libguile.a.
7915 * continuations.c (scm_make_cont): Enlarged the #if 0 around
7916 scm_relocate_chunk_to_heap.
7918 * debug.c: New file: low-level debugging support. It also
7919 includes support for debugging with gdb. (The extensions to gdb
7920 are written by Per Bothner at Cygnus.)
7922 * debug.h: New file: low-level debugging support.
7924 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
7925 argument pairs. Extensive modifications to the debugging
7926 evaluator. Added "SECTION:" commentaries to clarify what happens
7927 when, during double compilation. Renamed EVALIMP --> EVALIM.
7928 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
7929 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
7930 the beginning of the file. New procedure: scm_unmemocopy.
7931 Added some global state variables needed by the debugging
7932 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
7933 check_entry, check_apply, check_exit, debug_options and
7934 evaluator_traps. New acro: undefine.
7936 * eval.h: Renamed EVAL --> XEVAL.
7938 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
7939 --> scm_make_weak_key_hash_table.
7941 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
7942 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
7944 * libguile.h: Conditionally include debug.h
7946 * objprop.c (scm_object_properties, scm_set_object_properties_x):
7947 scm_object_properties shouldn't return handle. `handle' now gets
7948 initialized in scm_set_object_properties_x. scm_object_properties
7949 doesn't any longer create an entry in scm_object_whash.
7951 * options.c: New file: handling of run time options.
7953 * options.h: New file: handling of run time options.
7955 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
7957 * print.c: New procedure: scm_print_options
7959 * print.h: Defines for print options.
7961 * read.c: New procedure: scm_read_options
7963 * read.h: Defines for reader options.
7965 * root.h: Added scm_source_whash among scm_sys_protects.
7967 * srcprop.c: New file: source properties.
7969 * srcprop.h: New file: source properties.
7971 * throw.c (jbsmob): Jump buffers are now correctly allocated.
7972 (Bug found by A. Green.)
7974 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
7976 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
7978 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
7980 * libguile.h: #include "objprop.h"; I guess this was forgotten.
7982 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
7983 and should be called by the final client.
7985 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
7987 * gc.h: Use the PROTO macro when declaring functions.
7988 * gc.c: Use the PROTO macro when declaring static functions.
7989 Remove the CPP hair around function definitions.
7991 * gc.c (scm_init_storage): Initialize scm_asyncs.
7993 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
7994 preprocessor symbol; "__scm.h" is where it might get #defined.
7995 * __scm.h: Similar: #include <scmconfig.h> before testing
7998 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
8000 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
8002 * init.c (scm_boot_guile): Add init_func argument; call
8003 (*init_func) instead of calling scm_appinit; it's ucky to
8004 hard-code names for the user's procedures.
8005 * init.h (scm_boot_guile): Adjust declaration.
8007 * __scm.h (PROTO): New macro, for declaring functions with
8010 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
8011 eliminate all the __STDC__ conditionals.
8012 (scm_boot_guile): Add declaration.
8013 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
8014 Remove __STDC__ conditionals around function definitions; the
8015 declarations in init.h will provide the same information, more
8018 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
8019 complain about it in the error message; the error message is
8020 adequate without that note, and there's nothing the user can do
8023 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
8025 * Makefile.in (ancillary): Drop def.sed.
8027 * posix.c (scm_init_posix): Use numeric values, rather than
8028 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
8029 F_OK. The symbols aren't available on some systems, and I'm
8030 pretty sure their values are fixed by common widespread practice.
8031 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
8033 More functions unavailable on some systems.
8034 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
8035 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
8037 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8038 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
8039 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
8040 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
8041 stub that signals an error as the #else.
8043 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
8045 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
8047 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
8049 * unif.c: include ramap.h.
8051 * read.c (endif): case_insensative_p renamed case_insensitive_p.
8053 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
8055 * ports.c: include sys/ioctl.h.
8057 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
8059 * configure.in: check for sys/ioctl.h.
8061 * ports.c: include <malloc.h> not "malloc.h".
8063 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8065 * fports.c: remove ttyname and tmpnam declarations.
8067 * posix.c: fewer ttyname declarations.
8069 * fports.c: include <string.h> not "string.h".
8071 * init.c, ioext.c: include string.h and unistd.h.
8073 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8075 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
8076 genio.c, simpos.c, vports.c: include string.h.
8078 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
8080 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
8082 (scm_addr_buffer_size): change type from scm_sizet to int.
8083 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
8084 from scm_sizet to int.
8086 * error.c: include unistd.h.
8088 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
8091 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
8093 * __scm.hd, def.sed: deleted.
8095 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
8097 Changes for NeXT, suggested by Robert Brown.
8098 * configure.in: Call AC_TYPE_MODE_T.
8099 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
8100 NeXT. Put header file list in alphabetical order.
8101 * configure, scmconfig.h.in: Regenerated.
8102 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
8104 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
8107 * acconfig.h: New file, providing documentation for the CPP
8108 symbols defined in configure.in
8109 * acconfig-1.5.h: Removed; superceded by the above.
8111 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
8113 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
8115 * fports.c (scm_open_file): don't return #f, throw error.
8117 * ioext.c (fileno): renamed from %fileno.
8118 (soft-fileno): deleted.
8120 * ports.c (scm_port_revealed): don't need to check for -1 from
8122 (scm_set_port_revealed_x): return unspecified, not #f.
8124 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
8126 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
8128 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
8130 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
8132 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8134 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
8135 This is necessary on Ultrix, and doesn't hurt portability.
8137 * Makefile.in (dist-dir): New target, implementing a new dist system.
8138 (installed_h_files): Put in alphabetical order.
8139 Remove duplicate entries for markers.h and unif.h.
8140 (c_files): Remove duplicate entries for markers.c.
8141 (ancillary): Renamed from anillery; all uses changed. Remove
8142 PLUGIN; it's a directory, and needs special treatment in dist-dir.
8143 Remove all the ../doc/* files; doc/Makefile.in handles that.
8145 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
8147 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
8148 every if must have an else, or else the whole command has a
8149 non-zero exit code whenever the if's condition is false.
8151 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
8153 * posix.c: include string.h.
8155 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
8157 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
8160 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
8161 Remove leading % from scheme names.
8162 Do not return error values, call SCM_SYSERROR or similar.
8164 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
8166 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
8168 * struct.c (scm_init_struct): new file.
8170 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
8172 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
8173 (scm_list_head): added list-head for rapidly chopping argument
8174 lists off of longer lists (and similar).
8176 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
8178 * objprop.c (scm_object_property): assq the cdr of the whash
8179 handle for obj, not the handle itself.
8181 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
8183 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
8184 weak hash tables last of all marking to avoid an obscure gc bug.
8185 WARNING: circular lists stored in a weak hash table will hose us.
8187 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
8189 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
8190 new functions similar to scm_substring_move_left_x and
8191 scm_substring_move_right_x.
8193 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
8195 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
8198 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
8200 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
8202 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
8204 * strports.c (scm_strprint_obj): convenience function. C for
8205 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
8207 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
8208 removed to a separate library
8210 * init.c (scm_boot_guile): copied from guile-tcl.c.
8211 Initialization specific to tcl interpreters removed.
8213 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
8215 * ports.c (scm_ports_prehistory): size malloced here doesn't
8216 matter so long as it is non-0 (got rid of "* 4").
8218 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
8220 * gscm.h: gscm_mkarray eliminated (presumably was not being used
8221 since its definition was bogus).
8223 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
8225 * mallocs.[ch]: back again (for rx at least).
8227 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
8229 * ports.c: removed functions relating to the mapping between ports
8230 and descriptors. (That stuff is unix-specific and should be collected
8231 in a separate library).
8233 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
8234 (Tom Mckay@avanticorp.com)
8236 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
8238 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
8239 handled correctly (SCM_FREEP was applied to them) -- test for
8240 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
8241 being overwritten with #f. (brown@grettir.bibliotech.com)
8243 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
8245 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
8246 for a specific symbol or for all symbols.
8248 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
8250 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
8251 keys and weak values confused).
8253 Thu Mar 14 22:20:20 1996 Tom Lord <lord@beehive>
8255 * list.c (scm_last_pair): map '()=>'()
8257 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>
8259 * pairs.c, hashtab.c, list.c, alist.c append.c, sequences.c:
8260 Generalized assoc and hash-table functions.
8261 Factored pairs.c into multiple files.

8408 initialization to fix a race condition.
8410 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
