1 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
3 * fports.c (fport_input_waiting): if select is used, return 1
4 instead of whatever FD_ISSET expands to. maybe it will be useful
5 to interpret the value from the input_waiting ptob procedure as a
6 lower bound on the number of bytes available.
8 * Mikael asked for a few names to be changed...
10 * ports.c (scm_make_port_type): take the write procedure as the
11 second argument instead of the flush procedure.
12 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
13 fflush -> flush, read_flush -> end_input, fclose -> close,
14 fill_buffer -> fill_input, ftruncate -> truncate,
15 input_waiting_p -> input_waiting.
17 * ports.c (end_input_void_port): was read_flush_void_port.
18 (scm_set_port_end_input): was scm_set_port_flush_input.
19 (scm_set_port_flush): was scm_set_port_write.
20 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
21 (scm_end_input): was scm_read_flush.
22 (scm_fill_input): was scm_fill_buffer.
23 (scm_flush): was scm_fflush.
24 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
25 (fport_end_input): was local_read_flush.
26 (fport_flush): was local_fflush.
27 (fport_close): was local_fclose.
28 (fport_truncate): was local_ftruncate.
29 (fport_seek): was local_seek.
30 (fport_free): was local_free.
31 (fport_fill_input): was fport_fill_buffer.
32 * strports.c (st_end_input): was st_read_flush.
33 (st_truncate): was st_ftruncate.
34 * vports.c: (sf_flush): was sfflush.
35 (sf_close): was sfclose.
36 (sf_fill_input): was sf_fill_buffer.
38 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
41 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
43 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
44 forms now contain the expressions to be dispatched upon instead of
45 depending on a surrounding lambda or let; Generic function
46 dispatch has been optimized; `apply' on a generic function now
47 works a little bit strangely. It uses a trick so that the type
48 dispatch code in SCM_CEVAL can be reused.
50 * objects.h, objects.c (scm_apply_generic_env): Added (used by
52 (scm_operator_p): Added.
53 (scm_sym_atdispatch): Added.
54 (scm_set_object_procedure_x): Modified to handle the new style
56 (scm_object_procedures): New debugging procedure.
58 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
60 * eval.c, eval.h (scm_sym_args): Added.
62 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
64 * feature.c, feature.h (scm_c_run_hook): Added.
66 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
67 cdrxnoap and loopnoap instead of begin and loop.
69 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
71 * ports.c (scm_putc, scm_puts),
72 * unif.c (scm_uniform_array_write): use scm_lfwrite.
73 * ports.c (scm_putc): change type of first argument from int to char.
75 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
77 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
80 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
81 (scm_si_redfined, scm_si_hashsets): Moved.
83 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
84 flag which combines type and status info so that the class
85 redefinition protocol has zero cost during normal execution.
87 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
89 * ports.h (scm_ptob_descriptor): include a write procedure again.
90 it's more efficient for unbuffered fports (e.g., sockets.)
92 * ports.c (scm_puts): use ptob->write.
93 * vports.c (scm_make_sfptob): set write proc in ptob.
94 * strports.c (scm_make_stptob): set write proc in ptob.
95 * ports.c (write_void_port): new procedure.
96 * vports.c (sf_write): new procedure.
97 * ports.c (scm_lfwrite): use ptob->write.
98 * strports.c (st_write): new procedure.
99 * fports.c (fport_write): new procedure.
100 (scm_make_fptob): set write in ptob to fport_write.
101 * ports.h: prototype for scm_set_port_write.
102 * ports.c (scm_make_port_type): initialise ptob write procedure.
103 (scm_set_port_write): new proc.
105 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
107 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
108 until we've verified that it is actually a port. (Thanks to
111 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
113 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
114 code, particularly an unnecessary test (len != size, where len ==
115 size). (Was this leftovers from debugging code, or have I missed
118 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
119 size. (Thanks to James Dean Palmer.)
121 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
122 (Thanks to Lorentey Karoly.)
124 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
126 * eval.c (scm_m_expand_body): Use scm_cons_source.
128 * struct.c (scm_print_struct): Use vtable name.
130 * print.c (scm_init_print): Set name of print state type.
132 * stacks.c (scm_init_stacks): Set name of stack type.
134 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
136 * eval.c (SCM_CEVAL): Removed old implementation of internal
139 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
141 * debug.c, debug.h (scm_reverse_lookup): Added.
142 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
143 internal procedure definitions; Don't use scm_i_inner_name.
145 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
148 * eval.h: Added prototypes for multi language support functions.
150 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
151 improper lists in the low-level representation, since that will
152 cause a begin to be prepended at macro expansion.
154 * eval.c (scm_cons_source): Version of cons which copies source
155 properties from an existing cell.
156 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
158 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
159 procedure source before calling scm_unmemocopy instead of faking
162 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
164 Ported `internal defines' fix from SCM. Original ChangeLog entry:
166 1998-07-09 Radey Shouman <radey@colorage.com>
168 * eval.c (ceval_1): Modifications to allow rewriting of interal
169 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
170 body of which it is the CAR is macro expanded by m_expand_body,
171 which rewrites internal DEFINE.
173 (m_expand_body): Added.
175 (m_macroexp1): Added argument to control error checking:
176 m_expand_body may speculatively expand forms in the wrong
177 environments. Made argument number checks conditional on
180 (m_body): Added, error checks bodies and inserts the ISYM tokens.
182 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
185 (m_cond): (m_case): (m_quote): Modified to avoid destructively
186 changing their argument forms. Since m_expand_body
187 speculatively macro expands forms the process must be
190 (m_ident_eqp): Fixed to use proper environment.
192 (renamed_ident): Added DEFER_INTS_EGC.
194 Added prototypes for static functions.
200 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
201 is false, do not produce an error for unbound variables, return a
202 pointer to cell_undef instead.
204 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
208 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
209 destructively changing their argument forms. Since m_expand_body
210 speculatively macro expands forms the process must be reversible.
212 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
213 SCM_IM_LET introduced by named lets.
215 (scm_m_letstar): Use scm_m_body instead of bodycheck.
217 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
218 scm_letrec. scm_letrec1 does not check for a null binding and
219 takes an additional argument to specify the ISYM of the body. Use
220 scm_m_body instead of bodycheck.
222 (scm_m_let): Use scm_m_body instead of bodycheck.
224 (scm_m_expand_body, scm_macroexp): New.
226 (unmemocopy): Account for ISYMs introduced by scm_m_body.
228 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
229 check=1. Throw error for internal defined that have not been
230 rewritten by scm_m_expand_body.
232 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
233 Removed prototype for SCM_APPLY.
235 * tags.h: Added extern declaration of scm_isymnames.
237 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
239 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
241 * lang.c: New file: Beginning of multi-language support.
243 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
245 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
246 (scm_dynamic_wind): Added argument checking for the after guard so
247 that we don't add garbage on the dynwind chain.
248 (scm_swap_bindings): Added.
250 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
251 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
252 (scm_isymnames): New isyms for multi-language support.
254 * eval.c (scm_nil, scm_t): New symbols.
255 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
256 forms for multi-language support.
258 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
260 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
262 Renamed functions in the random function library interface
263 from scm_i_XXX --> scm_c_XXX.
265 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
267 * ports.c (scm_putc): fix line-buffering.
269 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
271 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
272 scm_set_ptob_XXX --> scm_set_port_XXX.
274 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
276 * ports.c, ports.h (scm_make_port_type): New interface for
277 creation of port types (replaces scm_newptob). Just as for the
278 smobs, we need to separate the internal representation of smob
279 types from the interface, so that we easily can add new fields and
280 rearrange things without caring about backward compatibility.
281 This change was forced by the need in GOOPS to create classes
282 representing port types.
283 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
284 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
285 scm_set_ptob_seek, scm_set_ptob_truncate,
286 scm_set_ptob_input_waiting_p): New setters.
287 (scm_newptob): Rewritten to use scm_make_port_type. For backward
289 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
290 (scm_prinport): Removed.
291 (scm_port_print): Added.
292 (scm_print_port_mode): Added.
293 (void_port_ptob, print_void_port, close_void_port, noop0):
294 Removed. Removed #include "genio.h" Added #include "objects.h",
297 * fports.c (prinfport): Moved code from ports.c.
299 (scm_fptob): Removed. Instead use new interface.
300 (scm_make_fptob): Added. (Need to create basic ports in a
301 specific order in ports.c.)
303 * strports.c (scm_stptob, prinstpt, noop0): Removed
304 (scm_make_stptob): Added.
306 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
307 (scm_make_sfport): Added.
309 * filesys.c (scm_dir_print): Don't use the port printing code.
310 Instead provide specific directory printer.
312 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
314 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
317 * smob.c (scm_smob_print): Handle non-existing type name nicely.
318 Removed #include "genio.h"
320 * objects.c (scm_make_port_classes): New function ptr.
322 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
324 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
326 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
327 allow the 1st argument to be a fdes or filename as well as a
328 port (as in the filesys.c version).
330 * filesys.c (scm_truncate_file): removed.
332 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
334 * readline.c, readline.h: Removed.
336 * objects.c, objects.h (scm_port_class): Added.
337 (scm_class_of): Look up port class in scm_port_class.
338 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
339 SCM_INOUT_PCLASS_INDEX): Added.
342 * Makefile.am: Removed genio.c, genio.x.
346 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
348 * init.c: Make sure that scm_post_boot_init_modules is called only
349 once. (Important when using a dumped image.; Thanks to Bernard
352 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
354 * guardians.c (scm_guardian_zombify): Separate scanning for
355 zombies from marking the pairs of the free list.
357 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
358 use the macros. (Thanks to Michael Livshin.)
360 * eval.c (scm_m_lambda): Let bodycheck check the body of the
361 lambda. Let your sins be purified by the blood of the lambda.
362 (Thanks to Eric Hanchrow.)
364 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
365 (Thanks to Valdis Kletnieks.)
367 Fixes for EMX from Mikael Ståldal.
369 * filesys.c: #include <io.h>, if we have it.
370 * scmconfig.h.in: Regenerated.
372 * stime.c (ftime): Delete declaration for this function --- let
373 the system supply it.
375 Cleanups from John Bley.
377 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
379 * gsubr.c: Don't include "gsubr.h" twice.
381 Cleanups for compilation on Irix 6, from David Kaelbling.
383 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
384 regex_t pointer. This is what the callers have, mostly.
385 (scm_regexp_exec): Don't forget to pass the `rx' argument to
386 scm_regexp_error_msg.
388 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
389 int. That way, if we get a warning on this line, it's more likely
390 that we're really missing bits we care about.
392 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
395 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
396 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
397 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
398 cast at all is more appropriate in every case. At the moment, we
399 assume everywhere that SCM is an integral type anyway.
401 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
403 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
404 read_pos after scm_fill_buffer.
406 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
409 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
410 fports.c (fport_fill_buffer): implement the interface change.
412 * ports.c (scm_fill_buffer): interface change: no longer increments
413 read_pos past the character that's returned. it seems clearer to
414 leave it to the caller to decide what to do (thanks Jim).
416 * vports.c (sf_fill_buffer): put the read char into the buffer
417 as well as returning it.
419 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure
422 1999-07-13 Gary Houston <ghouston@easynet.co.uk>
424 * strports.c (scm_strprint_obj): simplify. start with initial
426 (st_seek): don't allow string to be extended if seeking past
427 the end of a read-only port.
429 1999-07-12 Gary Houston <ghouston@easynet.co.uk>
431 * strports.c (st_seek): change the resize checks.
433 * ports.c (scm_ftruncate): throw error if offset works out negative.
435 * strports.c (st_flush): increase string size in blocks of
436 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
437 it's greater and reset read_buf_size.
438 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
439 to be maintained for output ports too (it holds the written
440 part of the string, while write_buf may have unwritten buffer
442 (st_truncate): rewritten.
443 (top of file): added a few notes.
445 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
447 Patch from Greg Badros:
448 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
449 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
450 (function pointer) argument to scm_make_gsubr and scm_make_subr
451 calls. This avoids warnings in C++ programs using guile-snarf.
453 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
455 * strports.c (st_grow_port): set pt->read_pos. set
456 pt->read_buf_size one less than pt->write_buf_size if there's
457 an unwritten char at the end of the string. similarly for
459 (st_resize_port): renamed from st_grow_port.
460 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
461 seek from read_end instead of write_end for SEEK_END.
462 (st_ftruncate): calculate current length using readbuf, not write
464 (scm_strport_to_string): use read_buf_size for length.

469 * strports.c (scm_strport_to_string): new procedure.
470 (scm_call_with_output_string, scm_strprint_obj): use
471 scm_strport_to_string.
472 used SCM_INUM0 instead of SCM_MAKINUM (0) in a few places.
474 1999-07-08 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
476 * symbols.c (scm_gensym): Bugfix. (Thanks to Johannes Hjorth.)
478 Fri Jun 25 22:14:32 1999 Greg Badros <gjb@cs.washington.edu>
480 * smob.c: added scm_make_smob_type_mfpe (), scm_set_smob_mfpe ();
481 use scm_make_smob_type_mfpe to initialize "free", "flo", "bigpos",
482 and "bigneg" smob types.
484 * smob.h: Add do ... while(0) idiom to SCM_NEWSMOB. Added
485 SCM_RETURN_NEWSMOB macro. Added protos for new functions in
488 * *.c: Use scm_make_smob_type_mfpe, instead of scm_newsmob, and
489 use SCM_NEWSMOB or SCM_RETURN_NEWSMOB in constructors instead of
490 SCM_NEWCELL and setting the CAR/CDR by hand.

577 1999-06-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
579 * struct.c, struct.h:
581 In order to support different kinds of deallocation, a destructor

645 qualifier for char* argument, to match prototypes. Thanks to Mark
648 1999-06-21 Jim Blandy <jimb@savonarola.red-bean.com>
650 * dynl.c (no_dynl_error, sysdep_dynl_link, sysdep_dynl_unlink,

656 Patch from Greg Harvey:
657 * eq.c, eval.c, list.c, ramap.c, vectors.c: Always write parens
658 around the condition of an `if', `while', etc., even if the
659 condition is a macro invocation that expands to something
660 surrounded by parens. It's more readable.
662 * eval.c (scm_map, scm_for_each): Verify that all arguments are
663 proper lists, and of the appropriate lengths.
664 (check_map_args): New function. (Thanks to Greg Harvey for the

698 Fix from Ken Raeburn <raeburn@raeburn.org>:
699 * weaks.c (scm_make_weak_vector): Add another extra slot before
700 vector contents, to be used only during garbage collection.
701 * weaks.h (SCM_WVECT_GC_CHAIN): New macro to access it.
702 * gc.c (scm_weak_vectors): Now a SCM instead of a SCM*, and now
704 (scm_weak_size, scm_n_weak): Deleted.
705 (scm_igc): Use SCM_WVECT_GC_CHAIN to build up a chain of weak
706 vectors without allocating new storage during GC, using
707 scm_weak_vectors as the head of the chain.
708 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
709 instead of stepping through an array.
710 (scm_gc_sweep): Update offset used to find start of weak vector to
712 (scm_init_storage): Set scm_weak_vectors to EOL.
714 Fix from Ken Raeburn <raeburn@raeburn.org>:
715 * gc.c (already_in_gc): New variable.
716 (scm_igc): Set and clear already_in_gc; abort if it's set at
719 1999-06-14 Jim Blandy <jimb@savonarola.red-bean.com>
721 Fix from Gary Houston:
722 * fports.c (local_seek): Signal an error if the seek fails.
723 * ports.c (scm_lseek): Don't check return value of port's seek
724 function; it's its job to signal an error if there's a problem.
726 1999-06-12 Jim Blandy <jimb@savonarola.red-bean.com>
728 * strports.c (scm_call_with_output_string): Don't include the

731 * ioext.c (scm_read_line): Switch to reading properly.
733 * fports.c, fports.h, gc.c, gdbint.c, ioext.c, ports.c, ports.h,
734 scmsigs.c, strports.c, vports.c: Install the sources which
735 actually correspond to the changes described below. I got the
736 ChangeLog entries and the patch from two different places...
738 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
740 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
741 it shows up as terrible performance, as we GC constantly.
743 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
744 newline. A bit faster, and definitely hairier.
745 (scm_read_line): Count newlines here instead.
747 * strings.c (scm_take_str): New function.
748 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h

753 * ports.h (SCM_BUFLINE): New flag for ports.
754 * init.c (scm_init_standard_ports): Request line-buffering on
755 the standard output port.

759 and there's a newline to be written, flush the port.
761 Gary Houston's open-buffer port patches:
763 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
765 * ports.c: (scm_lseek): clear buffers even if just reading current
768 * fports.c (local_fclose): call local_fflush unconditionally.

774 strports.c: take care of rw_active and rw_randow.
775 fports.c: scm_fport_drain_input: removed. do it all in ports.c.
776 strports.c (scm_mkstrport): check that pos is reasonable.
777 ioext.c (scm_ftell, scm_fseek): use lseek.
778 (SCM_CLEAR_BUFFERS): macro deleted.
779 ioext.c (redirect_port: use ptob fflush, read_flush.
780 ports.h (scm_ptobfuns): add ftruncate.
781 ports.c (scm_newptob): set ftruncate.
783 * ports.c (scm_ftruncate): new procedure.

785 strports.c (st_seek, st_grow_port): new procs.
786 fports.h (scm_port): change size types from int to off_t.
787 ports.c (scm_init_ports): initialise the seek symbols here
788 instead of in ioext.c.
789 strports.c (scm_call_with_output_string): start with an empty
790 string, so seek and ftruncate can be used.
792 gdbint.c: adjust string port usage.
794 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
796 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
797 equivalent to fflush for the read buffer.
798 * ports.c (scm_newptob): set read_flush.
799 ports.c (void_port_ptob): set read_flush.
800 fports.c (local_read_flush): new proc. add to ptob.
801 strport.c (st_read_flush): likewise.
802 vport.c (sf_read_flush): likewise.
803 fports.h (struct scm_fport): remove random member. there's nothing
804 left but fdes. leaving it as a struct to allow for future changes.
805 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
806 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
807 ptob proc if the read buffer is filled.
809 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
811 * ports.h (scm_port): add a rw_random member and replace
812 reading and writing members with rw_active member.
813 SCM_PORT_READ/SCM_PORT_WRITE: new values.
815 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
817 * ports.h (struct scm_port_table): add writing and reading members
818 to replace write_needs_seek: it isn't good enough for non-fports.
819 ports.c, ioext.c, fports.c: corresponding changes.
820 (struct scm_port_table): give it a typedef and rename to scm_port.
821 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
822 corresponding changes.
824 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
826 * ports.c (scm_newptob): bugfix: set seek member.
827 * * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
828 and generalised to all port types.
830 1999-04-18 Gary Houston <ghouston@easynet.co.uk>
832 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
833 signals (it was only being done for handlers installed from Scheme).
834 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
835 waiting for input caused an EINTR error from read.
837 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
839 * ports.h (struct scm_port_table): make all the char members
840 unsigned, so they convert to int without becoming negative if large.
842 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
844 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
845 with threads enabled. rename this procedure to
846 fport_wait_for_input and take a port instead of a fdes.
847 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
849 * readline.c (scm_readline): Applied a patch from Greg Harvey to
850 get readline support working again: use fdopen to get FILE objects.
852 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
854 * gc.c (scm_init_storage): install an atexit proc to flush the
856 (cleanup): the new proc. it sets a global variable which can be
857 checked by the ptob flush procs to avoid trying to throw
858 exceptions during exit. not very pleasant but it seems more reliable.
859 * fports.c (local_fflush): check terminating variable and if set
860 don't throw exception.
861 * CHECKME: that the atexit proc is installed if unexec used.
863 * throw.c (scm_handle_by_message): don't flush all ports here.
864 it still causes bus errors.
866 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
869 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
871 * ports.c (scm_char_ready_p): check the port buffer and call the
872 ptob entry if needed.
874 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
875 ptob initialisers. use it in char-ready
877 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
879 * vports.c (sfflush): modified to write a char (since softports
880 currently use shortbuf.)
882 * fports.c (scm_standard_stream_to_port): moved to init.c and
885 * init.c (scm_init_standard_ports): make stdout and stderr
886 unbuffered if connected to a terminal. with stdio they
887 were line-buffered by default.
889 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
892 * ports.h (scm_ptobfuns): change fflush return to void.
893 change flush proc definitions.
895 * strports.c (scm_call_with_output_string): get size from
896 buffer instead of port stream.
897 (st_flush): new proc.
899 * ports.h (struct scm_port_table): added write_end member,
900 as an optimisation. set it where write_buf_size is set.
902 * ports.h (struct scm_port_table): change stream from void *
903 back to SCM. SCM presumably must be large enough to hold a
904 pointer (and probably vice versa but who knows.)
905 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
907 (scm_puts): rewritten
908 * fports.c (local_ffwrite, local_fputs): removed.
909 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)

920 * ports.h (scm_ptobfuns): add seek function pointer.
921 * fports.c: set it to local_seek, new procedure.
924 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
925 use ptob for seek. take ptob instead of fport arg.
927 * ports.h (struct scm_port_table): new member write_needs_seek,
928 replaces reading member in fport struct.
930 * vports.c (sfgetc): store the getted char into the buffer.
931 rename to sf_fill_buffer and install it for fill-buffer in ptob.
932 the Scheme interface is still a procedure that gets a char.
933 (scm_make_soft_port): set up the port buffer (shortbuf).
935 * fports.c (local_fgetc, local_fgets): deleted.
936 * strports.c (stgetc): likewise.
937 * ports.c: scm_generic_fgets: likewise.
939 * ports.h (scm_ptobfuns): add fill_buffer.
940 * ports.c (scm_newptob): assign it.

942 put just the string into the stream, not cons (pos stream).
943 (stfill_buffer): new proc.
945 * ports.h: fport buffer moved into port table: to be
946 used for all port types.

955 scm_getpeername, scm_recv, scm_send, scm_recvfrom,
957 use SCM_FPORT_FDES. use SCM_OPFPORTP not SCM_FPORTP.
959 * posix.c (scm_getgroups): use SCM_ALLOW/DEFER_INTS.
960 (scm_ttyname): use SCM_FPORT_FDES.
961 (scm_tcgetpgrp, scm_tcsetpgrp): likewise.
963 * filesys.c (scm_chown): use SCM_FPORT_FDES.

989 vports.c (various places): use SCM_SSTREAM.
990 strports.c: likewise.
991 * gdbint.c: likewise.
992 * ports.h (SCM_SSTREAM): new macro.
994 * fports.c (scm_input_waiting_p): use scm_return_first, since port

1017 ports.c fports.c ioext.c posix.c socket.c net_db.c filesys.c:
1018 removed all uses of SCM_DEFER/ALLOW ints for now. they were mainly
1019 just protecting errno. some may need to be put back.

1223 * numbers.c (isfinite): Define this macro if not defined: Return a
1224 non-zero value if X is finite. (From ISO C 9x standard.)

1277 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1279 Most of this batch of changes is about how to deal with extended
1280 types when an object system is loaded into Guile. A nice object
1281 system is capable of representing Guile's types as class objects.
1283 For example, we want a regular expression to be of class <regex>.
1284 But regular expressions are smobs which aren't under direct
1285 control of the object system, so there has to be some mechanism
1286 which informs the object system that a new class should be created
1287 which can represent the smob type. I call this a "wrapper class".
1289 * objects.c: #include "smob.h";
1290 (scm_class_keyword): Removed. (Class is automatically created by
1292 (scm_smob_class): Array of smob classes indexed by smobnum.
1293 (scm_make_extended_class): "Plugin" function pointer for creation
1294 of wrapper classes for smob and struct types.
1295 (scm_class_of): Handle compiled closures. (Currently regarded as
1297 Use scm_smob_class to handle smob types;
1298 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
1299 through scm_smob_class;
1302 * smob.c (scm_newsmob): Also create a wrapper class if
1303 scm_smob_class has been initialized.
1305 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
1306 type code and smobnum.
1308 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
1309 (scm_struct_table): Weak key table with auxilliary information for
1310 struct types. Currently used for names and wrapper classes.
1311 (scm_struct_ihashq): Hash function for structs.
1312 (scm_struct_create_handle): Get/create entry in scm_struct_table.
1313 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
1314 for accessing names of vtables. The record implementation in
1315 boot-9.scm currently uses the setter to record the name of record
1316 types. When the object system is initialized, it can use this
1317 information to create wrapper classes with suitable names.
1318 (scm_init_struct): Allocate scm_struct_table.
1319 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
1320 (struct tags are a finite resource and we might want to restrict
1321 the use of tags to vtables only. E.g., Goops only uses tags for
1323 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
1325 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
1328 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
1329 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
1330 Used for access of struct table entries.
1332 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
1333 (scm_hash_fold): New procedure. Used to process all entries in a
1334 hash table (in no particular order).
1336 Argh! For the umpteenth time I got compilation errors because of
1337 the "intuitive" name `kw'. This has to have an end:
1339 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
1340 "kw" --> "keywords" everywhere.
1341 (I doubt that this will cause big compatibility problems since the
1342 application interface is unaffected.)
1344 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
1346 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1348 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
1349 column inums to native form.
1351 Improvement of backtraces: Introduces a new stack narrowing
1352 specifier, #t, for the inner cut. (See further in the comments in
1353 stacks.c:narrow_stack ().)
1355 * procprop.c, procprop.h (scm_sym_system_procedure): New symbol.
1356 (Used to flag certain system procedures which shouldn't turn up in
1359 * eval.c (scm_sym_system_module): New symbol. (Used to flag
1360 modules which aren't "user" modules and the code of which
1361 shouldn't turn up in backtraces.)

1364 Extract the lookup closure from an environment.
1365 (scm_system_module_env_p): New function: Return non-#f if MODULE
1368 * stacks.c: #include "eval.h"; #include "procprop.h";

1371 * debug.c (scm_procedure_name): Use name property in the default
1374 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
1376 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
1378 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
1379 procedure throughout.
1381 * print.c (scm_iprin1): Removed extraneous space when printing
1382 procedure-with-setters.
1384 Entity and operator setter slots were introduced as a complement
1385 to the <procedure-with-setter> type in order to support entities
1386 and operators with setters in a reasonable and efficient way.
1387 * procs.c (scm_procedure, scm_setter): Handle entity and operator
1390 * objects.h (SCM_OPERATOR_SETTER, SCM_ENTITY_SETTER): New macros.

1400 1999-03-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1402 * objects.h (SCM_OBJ_CLASS_REDEF): New macro: Find class slots
1403 directly through the instance.
1405 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
1407 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
1408 scm_struct_i_flags instead of scm_vtable_index_layout!
1410 * list.c (scm_list_star): New procedure.
1412 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1414 * debug.c (scm_init_debug): Added scheme level constant

1493 SYMB now point to const.
1495 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1497 * print.c (scm_iprin1): Use scm_procedure_name instead of
1498 scm_procedure_property for compiled closures.
1500 * tags.h (scm_tc7_pws): New procedure type. Four representations
1501 for procedure-with-setters were considered before selecting this
1504 1. A closure where the CODE and ENV slots are used to represent
1505 the getter and a new SETTER slot is used for the setter. The
1506 original getter is stored as a `getter' procedure property. For
1507 closure getters, the CODE and ENV slots contains a copy of the
1508 getter's CODE and ENV slots. For subr getters, the CODE contains
1511 2. A compiled closure with a call to the getter in the cclo
1512 procedure. The getter and setter are stored in slots 1 and 2.
1514 3. An entity (i.e. a struct with an associated procedure) with a
1515 call to the getter in the entity procedure and the setter stored
1516 in slot 0. The original getter is stored in slot 1.
1518 4. A new primitive procedure type supported in the evaluator. The
1519 getter and setter are stored in a GETTER and SETTER slot. A call
1520 to this procedure type results in a retrieval of the getter and a
1521 jump back to the correct eval dispatcher.
1523 Representation 4 was selected because of efficiency and
1526 Rep 1 has the advantage that there is zero penalty for closure
1527 getters, but primitive getters will get considerable overhead
1528 because the procedure-with-getter will be a closure which calls
1531 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
1532 <procedure-with-setter>, but together with rep 2 it suffers from a
1533 three level dispatch for non-GOOPS getters:
1535 cclo/struct --> dispatch proc --> getter
1537 This is because the dispatch procedure must take an extra initial
1538 argument (cclo for rep 2, struct for rep 3).
1540 Rep 4 has the single disadvantage that it uses up one tc7 type
1541 code, but the plan for uniform vectors will very likely free tc7
1542 codes, so this is probably no big problem. Also note that the
1543 GETTER and SETTER slots can live directly on the heap, using the
1544 new four-word cells.
1546 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,

1575 * eval.c: Renamed "set" --> "set_x" in various names for
1576 consistency of name correspondence between Scheme and C;
1577 Renamed scm_i_set_x --> scm_sym_set_x and made global.
1578 Renamed s_set_x --> scm_s_set_x and made global.
1580 1999-01-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1582 * random.c (scm_i_random_bignum): Made independent of endianness.

1600 scm_rstate from seed.
1601 (scm_copy_random_state, scm_seed_to_random_state): New functions.
1602 (scm_make_random_state): Removed.
1604 * random.c (scm_make_random_state): Use scm_i_make_rstate().

1612 1999-01-11 Roland Orre <mdj@mdj.nada.kth.se>
1614 * sort.c (scm_merge, scm_merge_list_x): Bugfix: Place elements
1615 from first arg before equal elements in second arg in result.
1616 (scm_merge_list_step): Bugfix: Don't presume that arguments in a C
1617 function call are executed in a well defined order.
1619 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
1621 * alloca.c (alloca): Cast value returned by malloc. (Thanks to
1624 1999-01-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1626 * random.c: Removed alloca includes.
1628 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
1630 * Makefile.in: This changed, for some reason I don't really
1631 understand, when I ran automake in the top level directory. This
1632 may be contamination by Cygnus internal releases. If you re-run
1633 automake and this change gets reverted, don't worry about it.
1635 1999-01-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1637 * sort.c, sort.h: New files: Implement slib's and scsh's sort

1650 * random.c, random.h: New files: Random number support.
1651 Interface same as slib's.
1653 * Makefile.am: Added random.c, random.h, random.x.
1655 * init.c: #include "random.h";

1658 1998-12-23 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1660 * Makefile.am: New files: guardians.c, guardians.x, guardians.h
1662 * guardians.c, guardians.h (scm_make_guardian,
1663 scm_guardian_gc_init, scm_guardian_zombify, scm_guard,
1664 scm_get_one_zombie, scm_init_guardian): This is an implementation
1665 of guardians as described in R. Kent Dybvig, Carl Bruggeman, and
1666 David Eby (1993) "Guardians in a Generation-Based Garbage
1667 Collector" ACM SIGPLAN Conference on Programming Language Design
1668 and Implementation, June 1993 ftp://ftp.cs.indiana.edu
1669 /pub/scheme-repository/doc/pubs/guardians.ps.gz
1670 Author: Michael N. Livshin.
1672 * gc.h (SCM_MARKEDP, SCM_NMARKEDP): New macros.
1674 * gc.c (scm_igc): Call scm_guardian_gc_init and
1675 scm_guardian_zombify.

1679 1998-12-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1681 * macros.c (scm_makacro, scm_makmacro, scm_makmmacro): Added
1684 1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1686 Move the procedure slots of entities to invisible slots (so that
1687 we can have operator class objects which themselves are entities).
1688 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
1689 SCM_STRUCTF_ENTITY): New constants.
1691 * struct.c (scm_make_struct): Allocate "invisible" room for
1692 procedures if SCM_STRUCTF_ENTITY is set in vtable.
1694 * gc.c (scm_gc_mark): Mark entity procedures.

1701 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0,
1702 SCM_ENTITY_PROC_3): Adjusted for new location of procedure slots.
1704 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
1706 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
1707 of syntactic forms, similar to SCM_PROC.
1708 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
1709 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
1710 for the name symbols when needed.
1712 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
1714 * Makefile.in: Regenerated.
1716 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
1718 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
1719 take the address of _into; it might be a register. Just have
1720 scm_debug_newcell return the new cell.
1721 * gc.c (scm_debug_newcell): Just return the new cell, instead of
1722 taking the address of a place to store it as an argument.
1723 * gc.h (scm_debug_newcell): Change declaration.
1724 (Thanks to Greg Harvey.)
1726 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1728 * ramap.c (array-copy-in-order!, array-map-in-order): New names.
1729 Replaces old names serial-array-copy! and serial-array-map!.

1735 * smob.c (freeprint): New function.
1736 (freecell): Use it to print freed objects, for slightly easier
1739 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1741 * backtrace.c (display_frame): Made more robust. Doesn't throw an
1742 error if no source properties can be found for a frame. (Thanks
1743 to Christian Lynbech.)
1745 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1747 * objects.h: Removed slots direct_supers and direct_slots from the
1748 definitions of the rudimentary classes described by objects.h.
1750 * objects.c, objects.h (scm_entity_p): New procedure. Together
1751 with the predicates scm_procedure_p and scm_struct_p, this
1752 predicate makes it possible to differ between structs, entities
1755 * modules.c, modules.h (scm_resolve_module): New function.
1757 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1759 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
1760 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
1763 * objects.c (scm_entity_p): New procedure.
1765 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
1766 for asubrs, rpsubrs, lsubrs and lsubr_2s.
1768 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1770 * procprop.h (scm_i_procedure_arity): Added declaration.
1772 * procprop.c (scm_i_procedure_arity): Made global; New code to
1773 handle operators and entities.
1774 (scm_procedure_property): No need to call scm_procedure_p since
1775 scm_i_procedure_arity now does all necessary type checking.
1776 Added #include "objects.h".
1778 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
1779 s_add_hook_x --> s_remove_hook_x.
1780 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
1781 Added #include "procprop.h"
1783 * feature.c, feature.h (scm_reset_hook_x): New procedure.
1784 (scm_make_hook): Optional argument defines number of arguments to
1786 (scm_make_named_hook): Take number of args as second arg.
1787 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
1788 boot-9.scm for a while); First arg is the hook. The rest are
1789 arguments passed on to the hook procedures.
1791 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
1793 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
1794 scm_logbit_p): Do the computation in ulongs. This is not as nice
1795 as doing it in bignums, but at least it's good enough for
1796 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
1798 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
1799 subexpressions. (Thanks to Charbel Jacquin.)
1801 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
1803 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
1804 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
1805 (scm_make_named_hook): New function.
1807 * feature.c: Added #include "eval.h".
1809 * modules.c (scm_make_module): Beautify the module.
1811 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1813 * modules.c, modules.h: New files: C interface to modules. (This
1814 is necessary in order to interface the object system to Guile
1815 properly. The guts of these modules will be replaced by the new
1816 module system in the future.)
1818 * init.c: Added #include "modules.h"
1819 (scm_boot_guile_1): Call scm_init_modules.
1820 (invoke_main_func): Call scm_post_boot_init_modules.
1822 * Makefile.am: Added modules.c, modules.x, modules.h.
1824 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
1826 * procs.c: #include "objects.h"
1827 (scm_procedure_p): Return #t also on structs which are operators.
1829 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
1830 <operator-metaclass> and <entity-class> to <standard-class>,
1831 <operator-class> and <entity> in order to conform with STKlos
1834 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
1835 which isn't an operator.
1836 (SCM_APPLY): Ditto, but jump to badproc.
1838 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
1840 * eval.c (SCM_CEVAL): Allow structs implanted in code.
1841 Previously, structs implanted in code were interpreted as forms
1842 the operator of which was a gloc. We solve this by checking for
1843 the zero in the emulated vcell in the struct vtable. Since
1844 implanted structs always will look like forms with a gloc
1845 operator, execution will only be slowed down by maximally one
1846 extra test-and-branch per application.
1848 * evalext.c (scm_definedp): Removed check for isyms; Added a
1849 second optional argument: It is now possible to supply an
1850 evaluation environment in which to look for the symbol.
1852 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1854 * readline.c (scm_init_readline): Set
1855 rl_basic_word_break_characters. (Thanks to Ian Grant.)
1857 * coop.c (coop_condition_variable_wait): Removed
1858 (coop_condition_variable_wait_mutex): Folded logic of
1859 coop_mutex_unlock into coop_condition_variable_wait_mutex to
1860 prevent condvar signal lossage. Previously, another thread could
1861 start to run after unlocking the mutex but before putting the
1862 current thread on the wait queue. If that thread then would
1863 signal the first, the signal would be lost. (Thanks to Christian
1866 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1868 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
1871 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1873 * objects.c (scm_i_make_class_object): Renamed from
1874 make_class_object; exported; error checking moved to
1875 scm_make_class_object and scm_make_subclass_object.
1876 (scm_make_class_object, scm_make_subclass_object): Use
1877 scm_i_make_class_object.
1878 (scm_make_subclass_object): Let the subclass have same metaclass
1881 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1883 * debug.c (scm_debug_options): Bugfix: Set the value of
1884 scm_stack_checking_enabled_p after setting debug options;
1885 #include "stackchk.h". (Thanks to Richard Polton.)
1887 1998-11-13 Radey Shouman <rshouman@metro2000.com>
1889 * unif.c (scm_array_contents): removed unnecessary test for 0
1892 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1894 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
1895 Replaced by macro `collect' in boot-9.scm.
1897 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1899 * eval.c (scm_copy_tree): Copy source properties if existent.
1901 * debug.c (scm_start_stack): Copy source when evaluating. (If we
1902 don't, we may end up passing memoized source to a transformer.)
1904 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1906 * stack.c (get_applybody): Help function which lookups the first
1907 body form of the apply closure.
1908 (read_frames): Prevent the source of the first form of the apply
1909 closure from being recorded. This would only be confusing.
1911 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
1912 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
1914 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
1916 * stacks.c (read_frame): Bugfix: Removed lingering `else'
1918 (read_frames): Use SCM_MACROEXPP.
1920 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1922 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
1923 don't contain interesting information since all arguments are
1924 present in the frame which applies the compiled closure anyway.);
1925 Skip the transformer application frames.
1927 * print.c (scm_iprin1): Print gsubrs as primitives.
1929 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1931 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
1933 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
1934 that we can identify these in a backtrace. (This change doesn't
1935 introduce any significant speed penalty.)
1937 * eval.c: Added note about `serial-map' using scm_map.
1939 * read.c, read.h (scm_read_options, scm_read_opts): Removed
1940 readline options. They should reside in their own options array.
1942 * readline.c, readline.h (scm_readline_options,
1943 scm_readline_opts): Moved readline options here.
1945 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1947 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
1948 SCM_ROCHARS instead of SCM_CHARS.
1950 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
1951 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
1953 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1955 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
1956 This is quite important since the latter clears the
1957 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
1958 every single character read...
1960 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1962 * print.c (scm_iprin1): Removed suspect looking (and indeed
1963 malevolent) semicolon after test for user supplied closure print
1964 procedure. (Thanks to Telford Tendys.)
1966 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
1967 (scm_memq, scm_memv, scm_member): Do argument checking *before*
1968 starting to search the list. Removed call to sloppy_mem_check.
1970 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
1971 procedures: Same as scm_delq_x et al, but delete maximally one
1974 * options.c (scm_options, scm_init_options): GC-protect option
1975 values of type SCM. (Thanks to Telford Tendys.)
1977 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1979 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
1980 make sure that there always is a "real" scm_lookupcar.
1982 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1984 * read.c, read.h (scm_read_opts): New read options
1985 "history-length" and "history-file".
1986 (scm_read_options): Stifle history to history length.
1988 * readline.c (scm_read_history, scm_write_history): New procedures.
1990 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1992 * eval.h (scm_macro_eval_x): Removed declaration.
1994 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
1995 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
1996 Renamed and made global.
1998 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
1999 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
2001 * evalext.c, evalext.h: New files. Contain non-R5RS things
2002 having to do with evaluation.
2004 * evalext.c (scm_serial_map): New procedure: Version of `map'
2005 which guarantees that the procedure is applied to the lists in
2007 (scm_m_sequence_to_list): New syntax: Version of `begin' which
2008 returns a list of the results of the body forms instead of the
2009 result of the last body form.
2010 (scm_definedp, scm_m_undefine): Moved from eval.c
2012 * evalext.h (scm_m_sequence_to_list): Added declaration.
2014 * macros.c, macros.h: New files.
2015 (scm_procedure_to_syntax, scm_procedure_to_macro,
2016 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
2017 scm_macro_name, scm_macro_transformer): Moved from eval.c
2018 (scm_make_synt): Moved from eval.c
2020 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
2022 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
2025 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
2027 * debug.c, print.c: Added #include "macros.h".
2029 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2031 This change adds the ability to use `unread-char' multiple times
2032 without interspersed reads and adds the new procedure
2033 `unread-string'. The change is optimized for the common case of
2034 unreading a single character. This is also the reason behind the
2035 choice to store characters in the port itself: in most cases no
2036 extra malloc is required.
2038 The amount of code in some macros in ports.h has been increased to
2039 the extent that they would fit better as C functions, but, since
2040 this code belongs to the port representation, such functions
2041 should be placed in ports.c which would cause calls back and forth
2042 between ports.c and genio.c. That is not good for performance.
2043 Also, keeping them as macros allows the compiler to do some
2044 optimizations which are needed to make the current interface
2045 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
2047 One benchmark (Guile startup time) indicates an increase of
2048 loading speed of 1%. Another (reading (using `read') boot-9.scm
2049 10 times) shows no change in performance.
2051 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
2052 made to find a beautiful solution.)
2054 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
2055 (SCM_TRY_CLRDY): New macro: Only clear the first unread
2056 character. (SCM_CLRDY clears all.)
2057 (SCM_N_READY_CHARS): New macro: Returns number of unread
2058 characters in a port. Returns wrong answer if SCM_CRDYP is false.
2059 (struct scm_port_table): New fields: `entry' contains port table
2060 index, `cp' points to last unread char, `cbuf' is the buffer for
2061 unread chars, `cbufend' points after end of the character buffer.
2063 * ports.h, ports.c (scm_unread_string): New procedure.
2064 (scm_grow_port_cbuf): New function.
2066 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
2068 (scm_generic_fgets), fports.c (local_fgets): Use a loop
2069 to read unread characters. Use SCM_TRY_CLRDY instead of
2072 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
2074 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
2076 * genio.c, genio.h (scm_ungets): New function.
2078 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
2081 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2083 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
2084 declarations. (Thanks to Russ McManus.)
2086 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2088 * numbers.c (num2long): As a software archeologist, I'm proud of
2089 this finding! :) Preliminary dating suggests an almost 4 year old
2090 remnant from the SCM ancestor. The sample has been removed from
2091 the finding site and is now safely stored in the repository.
2093 * numbers.h: Removed prototype for num2long.
2095 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
2097 * gh_data.c (gh_scm2doubles): Make it possible to pass result
2098 array as second arg.
2099 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
2100 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
2101 * gh.h: Updated and added prototypes.
2103 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
2105 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
2107 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
2109 * guile-snarf.in: Never generate an empty file. (Thanks to
2112 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
2113 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
2114 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
2115 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
2116 gh_new_procedure5_0): Specify argument types, to appease C++
2117 compilers. (Thanks to Brad Bowman.)
2119 Bug reports from Russ McManus:
2120 * guile-snarf.in: If the CPP environment variable is set, use that
2121 as the C preprocessor, instead of the preprocessor autoconf
2123 * snarf.h (SCM_PROC): Cast the function pointer passed to
2124 scm_make_gsubr, to satisfy C++.
2126 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2127 Use the handler passed, instead of ignoring it and using
2128 gh_standard_handler. (Thanks to Etienne Bernard.)
2130 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
2132 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
2135 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>
2137 * __scm.h, alist.c, async.c, async.h, backtrace.h, chars.c,

2152 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
2155 * script.c (scm_compile_shell_switches): Define
2156 use-emacs-interface in the root module, so the repl code can see
2157 it. See today's change to top-repl in ice-9/boot-9.scm.
2159 * filesys.c (set_element, get_element): Make sure that `element'
2160 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2161 Boekemeier and Jorgen "forcer" Schaefer.)
2163 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2165 * chars.c (scm_charnames): In ASCII character name table, make
2166 newlines print as #\newline by default, not #\nl.
2168 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2169 alphabetical order. Oh thrills. But it helps me know how far
2170 along in the compilation I am.
2171 * Makefile.in: Regenerated.
2173 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2175 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2176 #bytes(...) to #y(...), and syntax for short vectors from
2177 #short(...) to #h(...). This may seem nutty, but, like the other
2178 uniform vectors, byte vectors and short vectors want to have the
2179 same print and read syntax (and, more basic, want to have read
2180 syntax!). Changing the read syntax to use multiple characters
2181 after the hash sign breaks with the conventions used in R5RS and
2182 the conventions used for the other uniform vectors. It also
2183 introduces complexity in the current reader, both on the C and
2184 Scheme levels. (The Right solution is probably to change the
2185 syntax and prototypes for uniform vectors entirely.)
2187 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
2189 Don't use local_fgets on sockets; ftell doesn't work on sockets.
2190 (Thanks to Jorgen "forcer" Schaefer.)
2191 * ports.h (SCM_NOFTELL): New flag.
2192 * fports.c (local_fgets): If it's set, use the generic fgets.
2193 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
2195 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2197 * script.c (scm_compile_shell_switches): Add handling of -q switch
2198 (inhibit loading of user init file).
2199 (scm_shell_usage): Add usage text for -q switch.
2200 (scm_compile_shell_switches): Always load user init file first if
2201 it is loaded at all.
2203 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
2205 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
2206 and is now broken under NetBSD. I can't fathom what it's trying
2207 to do, so I've replaced it with something that I do understand,
2208 which seems to work, and which isn't broken on NetBSD. "Progress?
2209 You Decide." (Thanks to Perry Metzger.)
2211 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
2212 signed/unsigned comparison.
2214 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
2216 Warning fixes from Greg Harvey:
2217 * unif.c (scm_array_set_x): initializer for pos
2218 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
2219 * struct.c (scm_struct_ref, scm_struct_set_x): Added
2220 initializers for field_type, since EGCS so desparately wants to
2222 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
2223 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
2224 when GUILE_DEBUG is defined.
2225 * dynwind.h (scm_wind_chain): Same.
2226 * ports.h (scm_pt_size, scm_pt_member): Same.
2227 * print.h (scm_current_pstate): Same.
2228 * procs.h (scm_make_cclo): Same.
2230 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
2232 Handle short and long long uniform arrays properly. (Thanks to
2234 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
2235 raeql_1): Add cases for scm_tc7_svect (short vectors) and
2236 scm_tc7_llvect (long long vectors).
2238 Change the way libguile and boot-9.scm are timestamped, to try to
2239 get rid of these spurious mismatch warnings. Now both
2240 libguile/versiondat.h and ice-9/version.scm are generated directly
2241 by the configuration process, rather than having version.scm
2242 generated directly, and libguile/versiondat.h generated by the
2243 Makefile, which is generated by configure. It seems that
2244 sometimes the Makefile would change, but versiondat.h depends on
2245 Makefile.in, not Makefile, so it wouldn't get rebuilt.
2246 * Makefile.am (versiondat.h): Target removed; this is generated
2247 directly by the configure script now.
2248 (BUILT_SOURCES): Remove versiondat.h.
2249 * versiondat.h.in: New file, transformed by the configure script
2251 * Makefile.in: Regenerated.
2253 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
2254 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
2255 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
2256 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2257 if we want to use them in a header file some day, we can. (Thanks
2258 to Michael Livshin.)
2260 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2261 SCM numbers, so we won't have rollover problems; the range of a
2262 signed long in milliseconds is about 25 days. (Thanks to Karl
2265 Don't redefine sleep and usleep; fix this problem now.
2266 * coop.c (sleep, usleep): Remove declarations; we don't use or
2267 redefine these any more.
2268 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2269 job of usleep and sleep in a thread-friendly way. We can use
2270 these in the rest of Guile. Define versions for systems both with
2271 and without iselect.
2272 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2273 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2274 we're just using it, not redefining it, we can use a K&R style
2276 (sleep): Declare this, too, if the system hasn't.
2277 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2278 scm_uthread_sleep if they're available; otherwise, just call the
2280 * scmconfig.h.in: Regenerated.
2282 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2284 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2286 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2288 * threads.c: Doc fix.
2290 The argument type of usleep varies from system to system,
2291 as does the return type. We really shouldn't be redefining usleep
2292 at all, but I don't have time to clean that up before the 1.3.
2293 release. It's on the schedule for afterwards. (Thanks to Julian
2295 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2297 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2298 * scmconfig.h: Regenerated.
2300 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2301 right way to handle system variation. Autoconf's approach is the
2303 * simpos.h (scm_software_type): Declaration deleted.
2305 * script.c (scm_find_executable): Don't test if unix is #defined
2306 here; first, NetBSD doesn't #define it, and second, it's the wrong
2307 way to go about these things. (Thanks to Perry Metzger.)
2308 (dld_find_executable): Delete this MSDOS support code. This isn't
2309 the way we want to support this; it needs to be rethunk at a
2312 * genio.c (scm_do_read_line): Don't just politely check that the
2313 line was either non-empty or EOF. Abort if it's empty and not
2316 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2318 * scmconfig.h.in: Regenerated.
2320 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2323 * genio.c (scm_do_read_line): Count lines correctly when the file
2324 doesn't end in a newline.
2326 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
2328 * genio.c (scm_do_read_line): Maintain the line count correctly.
2329 (Thanks to Harvey J. Stein and Greg Harvey.)
2331 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
2334 * numbers.c (big2str): Protect t from garbage collection until
2335 we're done. (Thanks to Gary Houston.)
2337 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
2339 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
2341 * Makefile.in: Regenerated.
2343 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
2344 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
2347 Do magic to mix reads and writes on stdio FILE-based ports.
2348 (Thanks to Christian Lynbech.)
2349 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
2351 (pre_read, pre_write): New functions.
2352 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
2353 local_fputs): Call them.
2354 (local_fflush): Mark the port as ready for reading and writing.
2355 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
2356 flags on new port objects. This might not be accurate --- who
2357 knows what state the FILE * is in when we get it --- but it won't
2358 do extraneous calls to fflush or fseek, so it's no worse than the
2359 behavior before this change.
2360 * ports.h: Add comment.
2362 Centralize the creation of port objects based on stdio FILE * in
2363 fports.c; don't just throw them together anywhere.
2364 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
2365 what the rest of Guile wants. Don't set the revealed count;
2366 that's only appropriate for stdin, stdout, stderr.
2367 (scm_standard_stream_to_port): This function does set the revealed
2369 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
2370 not scm_stdio_to_port.
2371 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
2372 * fports.c (scm_open_file): Same.
2373 * posix.c (scm_pipe): Same.
2374 * socket.c (scm_sock_fd_to_port): Same.
2375 * ioext.c (scm_fdopen): Same.
2376 (scm_freopen): Moved from here to...
2377 * fports.c (scm_freopen): ... here. This is really something that
2378 munges the internals of an fport, so it should go here.
2379 * fports.h (scm_stdio_to_port): Adjust prototype.
2380 (scm_standard_stream_to_port, scm_freopen): New protoypes.
2381 * ioext.h (scm_freopen): Prototype removed.
2383 * filesys.c (set_element, get_element): This can work on both pipe
2384 and file ports, so use SCM_FPORTP to typecheck, instead of testing
2387 * scmconfig.h.in: Regenerated.
2389 Change the definition of the functions in scm_ptobfuns so that
2390 they get passed the port object, not the port's stream.
2391 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
2392 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
2393 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
2394 Pass the port itself to the scm_ptobs function.
2395 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
2396 scm_generic_fgets): Same.
2397 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
2398 getc_void_port, fgets_void_port, close_void_port): Just change the
2399 argument names; these functions don't really do anything.
2400 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
2401 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
2402 port as an argument, and use SCM_STREAM to get the stdio FILE *.
2403 Also, use prototyped definitions, and get rid of the extra
2405 (scm_fptob, scm_pipob): We don't need casts here any more.
2406 * strports.c (prinstpt): Use prototype declarations.
2407 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
2408 and use SCM_STREAM to get the string info. Also, use prototyped
2409 definitions, and get rid of the extra declarations.
2410 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
2413 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
2414 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
2416 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
2417 scm_fgets, for consistency.
2418 (scm_fptop, scm_pipob): References updated.
2420 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
2422 Include the source location in error messages for scripts.
2423 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
2424 stack is still there when we catch the error.
2425 * throw.c (handler_message): If we are handling an error with a
2426 message, then put together the proper arguments and call
2427 scm_display_error, instead of scm_display_error_message. That
2428 displays source location, if it can find it.
2430 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
2432 * gc.c (scm_unprotect_object): Change this so that calls to
2433 scm_protect_object and scm_unprotect_object nest properly.
2434 (scm_protect_object): Doc fixes.
2436 * strings.c (scm_string_set_x): Require the argument to be a
2437 writable string, not a substring or a symbol.
2438 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
2439 (Thanks to John Redford and Charbel Jacquin.)
2441 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
2443 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
2445 * eval.c (safe_setjmp): Remove this misunderstanding.
2446 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
2449 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
2451 * libguile.h: Mark these as C declarations, for compilation by C++
2454 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
2455 __cplusplus clause. I seriously doubt this ever worked the way
2456 the author seems to have intended.
2458 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
2460 Utterly needless cleanups to hopelessly messy code.
2461 * ports.c: Doc fixes.
2462 (scm_fflush): Moved to ...
2463 * genio.c (scm_fflush): ... here, amongst all the other port
2464 method invocation functions.
2465 * genio.h, ports.h: The prototype moves too.
2467 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
2469 * backtrace.c (display_error_body): The current frame does not
2470 always have a parent frame; consider a function called directly
2471 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
2474 * alloca.c (alloca): Undo yesterday's changes, and simply call
2475 malloc directly for storage, and abort if we don't get what we
2476 want. The situation is much simpler --- just call malloc. Emacs
2477 has bizarre/evil requirements (signal handlers might malloc unless
2478 you set this global flag, so you have to set the flag around all
2479 calls to malloc) which we are certainly not going to conform to,
2480 so we can do the simple and obvious thing.
2482 * coop.c (coop_condition_variable_wait): Make this function
2483 static. It's only useful internally --- you should never just
2484 wait on a condition variable.
2485 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
2487 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2489 * unif.c (scm_array_set_x): Accept any kind of number as an
2490 element for a uniform vector of doubles. This is more consistent
2491 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
2493 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
2494 works; I can't conveniently test it myself. (Thanks to Dvid
2495 Tillman for the bug report.)
2497 * init.c: Doc fixes.
2499 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
2500 from here, not from scm_compile_shell_switches (which is a pretty
2501 dumb place to do it).
2502 (scm_load_startup_files): New function.
2503 (scm_ice_9_already_loaded): Variable moved to here from script.c.
2504 * script.c (scm_compile_shell_switches): Don't load the startup
2506 (scm_ice_9_already_loaded): Variable moved.
2507 * init.c (scm_load_startup_files): Prototype for new function.
2508 * gh_init.c (gh_enter): Doc fix.
2510 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2512 Some anti-warning changes from Greg Harvey.
2513 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
2514 warnings when it doesn't understand our NORETURN declarations in
2516 * posix.c (scm_mknod): Similar.
2518 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2520 * posix.c (scm_getpwuid): If we can't find an entry, return our
2521 own message, instead of using scm_syserror --- the getpwMUMBLE
2522 functions don't set `errno' to anything interesting.
2524 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2526 Get rid of warnings from the cooperative threading system.
2527 * threads.h (scm_single_thread_p, scm_yield,
2528 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
2529 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
2530 scm_wait_condition_variable, scm_signal_condition_variable): Add
2531 prototypes for these Scheme-visible functions.
2532 * coop-defs.h (coop_next_runnable_thread,
2533 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
2534 Prototypes for these here, even though they're from iselect.c.
2535 (coop_condition_variable_wait, coop_join): Add prototypes.
2536 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
2537 scm_threads_free_condvar): Make these smob functions static.
2538 * coop-threads.h (coop_init): Give this a real prototype.
2539 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
2540 (coop_next_runnable_thread): No need to provide prototype; it's in
2543 * scmconfig.h.in: .detarenegeR
2545 * iselect.c, threads.c: Doc fixes.
2547 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2549 * Makefile.in: Regenerated with a patched automake, to get
2550 dependency generation right when using EGCS.
2552 * inet_aton.c (inet_aton): Add prototype, to remove compiler
2553 warning. (Thanks to Robert Pluim.)
2555 * inet_aton.c (inet_aton): Reassure the compiler that the
2556 arguments to the <ctype.h> macros are all unsigned characters, not
2559 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2561 Getting rid of more warnings...
2562 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
2563 today's change to ../configure.in.
2564 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
2565 * scmconfig.h.in: Regenertaded.de.,.__
2566 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
2567 (scm_localtime, scm_mktime): Use a const char * to manipulate the
2570 * readline.c: Doc fix.
2571 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
2572 * readline.h (scm_filename_completion_function): Add prototype.
2573 (scm_init_readline): Make this into a prototype.
2575 * readline.c (scm_filename_completion_function): Use SCM_PROC to
2576 declare this, instead of calling scm_make_subr manually.
2578 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
2580 * readline.h (scm_init_readline): Add prototype for this.
2581 (scm_init_readline): Make this a real prototype.
2583 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
2585 Warning fixes from Maciej Stachowiak:
2586 * backtrace.h (scm_display_application, scm_backtrace): Add
2588 * debug.c (scm_m_start_stack): Make this function static.
2589 * fluids.h (scm_fluid_p): Add prototype.
2590 * procprop.c (scm_i_procedure_arity): Make this function static.
2591 * regex-posix.c (scm_regexp_error_msg): Make this function static.
2592 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
2593 * root.h (scm_dynamic_root): Add external prototype.
2594 * scmsigs.h (scm_usleep): Add external prototype.
2595 * script.h (scm_init_script): Use prototype, not K&R decl.
2596 * stacks.h (scm_stack_id): Add external prototype.
2597 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
2599 1998-09-30 Mark Galassi <rosalia@cygnus.com>
2601 * gh.h: took out the definitions of vset and vref, since they are
2602 replaced by the proper vector routines that correspond to the R4RS
2605 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
2607 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
2608 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
2609 third argument, a C expression that should result in a SCM value,
2610 which is used to initialize the variable. Reimplemented
2611 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
2614 * version.h (scm_libguile_config_stamp): Add prototype.
2615 (From Maciej Stachowiak.)
2617 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
2619 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
2620 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
2622 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
2624 * print.c (scm_iprin1): Rather than having one i, and using it in
2625 several places, declare a fresh i local to each block where it is
2626 used, and give it a signedness appropriate to its use in each case.
2627 (scm_iprlist): Same.
2629 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
2630 comparison warnings.
2632 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
2633 signed/unsigned clashes.
2635 * posix.h (scm_tmpnam): Added prototype.
2637 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
2638 scm_make_subclass_object): Add external prototypes.
2640 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
2641 comparison is okay here.
2643 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
2645 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
2646 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
2648 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
2651 * load.c (swap_port): Make this function static.
2653 * load.c (scm_search_path): Make max_path_len and max_ext_len
2654 unsigned, since they're compared against string sizes.
2656 * load.c (init_build_info): Make i unsigned.
2658 * ioext.h (scm_read_line): Add prototype.
2660 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
2661 scm_hash_fn_remove_x): Make hash bucket index local variable k
2662 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
2663 accurately as possible.
2665 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
2666 comparisons, and range checking to make sure those casts are
2669 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
2670 signed/unsigned comparisons.
2672 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
2673 avoid signed/unsigned comparisons.
2674 * smob.h (scm_numsmob): Change extern declaration to match.
2676 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
2677 avoid signed/unsigned comparisons.
2678 * ports.h (scm_numptob): Change extern declaration to match.
2679 (scm_current_load_port, scm_set_port_line_x,
2680 scm_set_port_column_x): New prototypes.
2682 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
2683 test code, and it causes warnings.
2685 * gh.h (gh_int2scmb, gh_uniform_vector_length,
2686 gh_uniform_vector_ref): Added prototypes.
2688 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
2689 debugging support unconditionally. That's backtrace.c, stack.c,
2690 debug.c, and srcprop.c.
2691 (EXTRA_libguile_la_SOURCES): Omit those from here.
2692 * Makefile.in: Regenerated.
2694 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2696 * options.c (scm_options): Bugfix: Allow empty list of options!
2698 * debug.c, debug.h (scm_single_step): Removed.
2699 (scm_with_traps): New procedure. This procedure could easily be
2700 written in Scheme but needs to be highly optimized.
2702 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
2704 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
2705 Check SCM_TRAPS_P before trapping.
2707 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
2709 Changes to avoid signed/unsigned comparison warnings.
2710 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
2711 (scm_gc_sweep): Make n and j local to the blocks they're used in,
2712 so they can have appropriate types for each application. Make i
2713 signed. Use initializers in some spots. I'll probably pay for
2715 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
2716 (scm_must_realloc): Make nm unsigned.
2717 (init_heap_seg): Make new_seg_index and n_new_objects signed.
2718 (scm_init_storage): Use prototype-style definition, and make the
2720 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
2721 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
2723 * filesys.c (scm_readlink): Make local vars rv and size ints, to
2724 avoid signed/unsigned comparison warnings, and because the return
2725 value of readlink may be -1. Don't bother casting the third
2726 argument to readlink.
2728 * filesys.c (scm_dirname, scm_basename): Move these to their own
2729 page, at the end of the file.
2730 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
2732 * eval.h (scm_eval_options_interface): Add external prototype for this.
2733 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
2735 * eval.c (scm_lookupcar1): Make this static.
2737 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
2738 Make these prototype declarations, not K&R-style.
2740 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
2741 unsigned comparison warning.
2743 * appinit.c: File removed. It had a single function in it, empty,
2744 whose reason for existence is explained in no documentation or
2745 comment. I think it's there as a default for some Tcl-style
2746 initialization, but Tcl abandoned that approach a while ago.
2747 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
2748 (BUILT_SOURCES): Remove appinit.x.
2749 * Makefile.in: Regenerated.
2751 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
2753 * Makefile.in: Regenerated using the last public version of
2754 automake, not the hacked Cygnus version.
2756 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
2758 Remove Totoro kludge.
2759 * Makefile.in, scmconfig.h.in: Regenerated.
2760 * init.c, readline.c: Don't check if TOTORO is #defined.
2762 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
2764 * Makefile.am: Adjust for new thread configuration system.
2765 (INCLUDES): Include the value of THREAD_CPPFLAGS.
2766 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
2768 (THREAD_LIBS): Definition deleted; automake will generate such
2769 things automatically.
2770 * Makefile.in: Regenerated.
2772 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
2774 Simplify smob and port marking; set the mark bit in the generic
2775 marking code, and make marker routines only responsible for
2776 turning up outgoing pointers.
2777 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
2778 before calling the marking function. Don't call the marking
2779 function if it's zero.
2780 * markers.c (scm_mark0): Just return #f. This function isn't
2781 necessary at all now, but it's harmless to call it. We'll leave
2782 it in so other folks' code doesn't croak at link time.
2783 (scm_markcdr): Don't call SCM_SETGC8MARK.
2784 * async.c (mark_async): Don't call SCM_SETGC8MARK.
2785 * dynl.c (mark_dynl_obj): Same.
2786 * root.c (mark_root): Same.
2787 * srcprop.c (marksrcprops): Same.
2788 * unif.c (markra): Same.
2789 * variable.c (scm_markvar): Same.
2790 * ports.c (scm_markstream): Same.
2791 (void_port_ptob): Specify zero for our marking function.
2792 * debug.c (debugobjsmob): Same.
2793 * dynwind.c (guardsmob): Same.
2794 * filesys.c (dir_smob): Same.
2795 * fluids.c (fluid_smob): Same.
2796 * fports.c (scm_fptob, scm_pipob): Same.
2797 * mallocs.c (mallocsmob): Same.
2798 * regex-posix.c (regex_t_smob): Same.
2799 * smob.c (freecell, flob, bigob): Same.
2800 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
2801 * throw.c (jbsmob, lazy_catch_funs): Same.
2803 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2805 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
2806 scm_copy_tree on code in order not to let memoized code to leak
2807 out. Thus, scm_copy_tree needs to copy vectors as well since
2808 quasiquote can introduce evaluated code also inside vector
2811 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2813 * eval.c (scm_copy_tree): Removed ability to copy vectors.
2815 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
2816 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
2819 * unif.c: Say that ivect and uvect are of type signed and unsigned
2820 long instead of int in commentary so that it correctly describes
2823 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2825 * stime.c: Removed declaration of strptime. (It should be
2826 declared by the system headers. If it turns out that some systems
2827 don't, we'll handle that then.) (Thanks to Greg Troxel.)
2829 * stime.h: Renamed TIMEH --> STIMEH
2831 * backtrace.c (scm_display_error, scm_display_backtrace): In order
2832 to increase portability, don't use structure assignment.
2833 (Thanks to Nicolas Neuss.)
2835 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
2837 (finalize_fd_sets): Added empty statement after last case label.
2838 (Thanks to Nicolas Neuss.)
2840 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
2843 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
2845 * init.c, readline.c: OK, I won't have these readline.x bug
2846 reports anymore. We've had them since April. The current reason
2847 is a completely unintelligible failure of totoro.red-bean.com to
2848 do the test for rl_getc_function in libreadline correctly. This
2849 kludge overrides the test if we're on totoro so that the snapshot
2850 generation process can work.
2852 * readline.c: Define a strdup replacement if not existent on system.
2854 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2856 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
2857 This change makes scm_make_vector R5RS compatible. We cannot keep
2858 the third argument since people want to be able to deduce the form
2859 of the C function call only by looking at R5RS. (At the same time
2860 we have removed some unnecessary complexity!)
2862 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
2863 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
2864 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
2865 argument in call to scm_make_vector.
2867 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2869 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
2870 This macro is useful in applications.
2872 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2874 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
2875 (scm_parse_path, scm_search_path): New Scheme level procedures.
2877 * load.h (scm_internal_parse_path, scm_parse_path,
2878 scm_search_path): Declared.
2880 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2882 * filesys.c (dirname, basename): New procedures.
2884 * init.c (scm_boot_guile_1): Removed condition around
2887 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
2888 new data type (guards) for representation of C level guards and
2889 data on the wind chain.
2890 (scm_internal_dynamic_wind): New function.
2892 * dynwind.h: Declare scm_internal_dynamic_wind.
2894 * root.h (scm_root_state): Added scm_cur_loadp.
2896 * root.c (mark_root): Added comment about cur_loadp.
2898 * load.c: #include "dynwind.h";
2899 (scm_primitive_load): Use scm_inner_dynamic_wind to update
2902 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
2904 * ports.c (current-load-port): New procedure.
2906 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2908 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
2909 not a tty, return #f.
2911 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
2912 to Julian Satchell and Roland Kaufmann.)
2914 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
2915 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
2917 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2919 * debug.h, debug.c (scm_start_stack): New function. Implements
2920 the guts of old scm_m_start_stack.
2922 * debug.c (scm_m_start_stack): Use scm_start_stack.
2924 * init.c (scm_start_stack, scm_restart_stack): Renamed to
2925 start_stack and restart_stack. (These have static scope.)
2927 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2929 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
2930 readline functions to come in release 2.3. (Thanks to Chet
2932 (handle_errors): Use the above functions.
2934 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2936 * readline.c: Improvements for readline support: Handle errors
2937 better; Implement before-read-hook.
2939 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2941 * init.c (scm_boot_guile_1), readline.c: Test for
2942 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
2943 assure that we have version >= 2.1.)
2945 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
2947 * readline.c (scm_readline): Defer interrupts while we're calling
2950 * readline.c (scm_add_history): Bugfix: Do strdup before giving
2951 away the string to add_history.
2952 (completion_function): Do completion for readline. (Thanks to
2954 (scm_filename_completion_function): New procedure: Filename
2956 (current_input_getc): New function. Use this one instead of
2957 standard getc from readline.
2959 * throw.c, throw.h (scm_handle_by_throw): New function: This
2960 handler throws errors to next handler on the dynwind chain.
2962 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
2964 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
2967 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2969 * procprop.c (scm_i_procedure_arity): New function. Returns arity
2971 (scm_procedure_properties): Modified to return arity together with
2973 (scm_procedure_property): Added the read-only property `arity'.
2974 (scm_set_procedure_property_x): It is an error to set the `arity'
2977 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
2978 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
2980 * procprop.h (scm_sym_arity): New symbol.
2982 * objects.c (scm_set_object_procedure_x): New procedure: Use this
2983 to set the dispatch procedure of an operator or entity object.
2985 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
2986 Made procedure slots read-only.
2988 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
2989 scm_tcs_cons_gloc case in zero args switch; Fixed args
2990 construction for operators in scm_tcs_cons_gloc case in two args
2993 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2995 * fluids.c: Removed use of assert.h (in order to avoid
2998 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
3000 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
3002 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
3003 change makes the evaluator safer at the cost of evaluation speed.
3004 It handles the case when the user has added a non-immediate
3005 improper end of the application form, e.g., `(+ 0 . x)'.
3006 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
3007 minimize the extra cost as much as possible. The new code is
3008 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
3009 problem with structs planted directly in the code (e.g. by a
3010 macro). This no longer causes segmentation fault. (Thanks to
3013 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
3014 arg `proc' in order to be able to throw errors; New argument
3017 * Removed extra #include "debug.h"
3019 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
3021 * scmsigs.c: Declare usleep as returning void on some systems.
3022 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
3025 * coop.c (usleep): Return void on some systems.
3027 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3029 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
3031 * coop.c: Changed return type of usleep to int.
3033 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
3034 isn't found in the OS.
3036 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
3037 isn't enabled. (Thought that I had made this change ages ago...)
3039 * iselect.c: Declare bzero if not defined by OS.
3041 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3043 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
3044 condition. (Thanks to John Tobey.)
3046 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
3047 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
3050 * __scm.h: Start the long-term project of moving to POSIX threads.
3051 Phase 1: Classification of all critical sections.
3052 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
3053 for A sections. (See comments in __scm.h for details.)
3055 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
3056 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
3058 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3060 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
3061 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
3062 (libpath.h, versiondat.h): Replaced dependency on Makefile with
3063 dependencies on $(srcdir)/Makefile.in
3064 $(top_builddir)/config.status in order to avoid circularity.
3066 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
3067 from argc if argc was 0 initially.
3069 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
3070 in generation of libpath.h.
3072 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
3074 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
3075 libguile from 2 to 3.
3077 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
3079 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
3081 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
3083 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
3084 scm_set_port_column_x, scm_port_filename,
3085 scm_set_port_filename_x): Removed optional arguments. Added
3086 proper argument checking.
3088 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
3089 stack size in machine words.
3091 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
3092 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
3093 to Ole Myren Röhne.)
3095 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
3097 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
3098 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
3100 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
3103 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
3104 procedure apply: Copy argument lists before pushing them unto the
3105 environment so that the environment won't get mutated due to
3106 manipulation of procedure arguments. This should perhaps be
3107 regarded as a temporary solution until someone finds a more
3108 efficient one. (Thanks to Maciej Stachowiak.)
3110 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
3112 * script.c (scm_compile_shell_switches): Use "guile" as default
3113 zero arg if argc is NULL.
3115 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
3117 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
3118 is zero. (Thanks to Dirk Herrmann.)
3120 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
3122 * ports.c (scm_add_to_port_table): First line is now line 0
3123 (was 1). (Interface changed according to suggestion by Per
3126 * backtrace.c (display_header): Add 1 to line and column numbers
3127 when presenting them to the user.
3129 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3130 from debug.c --> eval.c
3132 * eval.h, eval.c (scm_eval_options_interface): New options
3134 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3135 i.e. stacks for new threads.
3137 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3139 * eval.c (unsafe_setjmp): Removed with #if 0.
3141 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3144 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3145 to avoid compiler warnings.
3147 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3149 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3151 * throw.c (handler_message): Print message on current error port
3152 instead of default error port. (Thanks to Maciej Stachowiak.)
3154 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3156 * ports.c (scm_add_to_port_table): allocate in units of
3157 struct scm_port_table *, not struct scm_port_table.
3158 * posix.c (scm_close_pipe): remove the port from the port table
3160 Thanks to Rob Engle for both fixes.
3162 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3164 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3165 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3167 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3169 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3171 * backtrace.c (display_error_body, display_backtrace_body),
3172 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
3173 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
3174 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3175 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
3178 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
3179 don't receive the jmpbuf arg anylonger.
3180 (scm_catch): Don't accept a #f tag.
3181 (scm_throw): Check that key is a symbol.
3182 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
3184 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
3186 * async.c (async_pending): Removed declaration.
3188 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3190 * dynwind.c (scm_wind_chain): New debug function.
3192 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
3193 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
3194 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
3195 extra layer of functions around the body and handler of a thread.
3196 This extra layer makes sure that the handler is called in the
3197 dynamic context of the surround (= empty dynwind list), but under
3198 the *dynamic root* of the body. We can not use the dynamic root
3199 of the surround since that root belongs to another thread => stack
3200 is not handled correctly. It may seem ugly to use this extra
3201 layer, but the extra cost in terms of execution time is really
3202 negligible compared to the total amount of time required to create
3203 a thread, and it would reduce maintainability to duplicate the
3204 crucial and complicated steps performed by cwdr.
3206 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
3207 (SCM_ALLOW_INTS): Added thread switching code before interrupts
3208 get re-enabled. The important effect of this is that interrupts
3209 are blocked during thread switching so that thread data structures
3210 don't risk getting messed up by an unfortunate signal.
3211 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
3212 seems to do more aggressive optimization which actually move
3213 instructions around in these macros in a fatal way. Therefore:
3214 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
3215 just superstitious...)
3216 (SCM_TICK): Maybe do a context switch and take care of asyncs.
3217 This macro should be used instead of SCM_ASYNC_TICK since the
3218 latter doesn't do context switches any more.
3220 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
3221 instead of SCM_ASYNC_TICK.
3223 * coop.c, iselect.c: Since thread switches are now performed with
3224 interrupts masked, we can't use the old mechanism of delivering
3225 signals immediately when they arrive. Signals must instead be
3226 delivered when the asyncs run *after* the end of the critical
3227 section in scm_internal_select. But this also means after context
3228 switch so that the signal will be delivered to a different thread.
3229 To avoid this, I have changed the protocol of
3230 coop_wait_for_runnable_thread and friends so that they are allowed
3231 to return the original thread. So, if a signal arrives during
3232 scm_internal_select, we won't any longer be forced do a context
3233 switch, but can remain in the same thread and deliver the signal
3236 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
3237 scm_asyncs_pending and made it global.
3239 * iselect.c: Small fixes.
3241 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
3242 coop_condition_variable_init, coop_condition_variable_wait,
3243 coop_condition_variable_signal): Changed return type from `void'
3244 to `int'. This is to adhere closer to the pthreads interface.
3245 This, in turn, is part of an attempt to provide C versions of the
3246 mutex and condition variable primitives which can be part of a
3247 frontend to COOP or pthreads.
3249 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
3250 coop_condition_variable_destroy): New functions.
3252 * coop-threads.c (scm_wait_condition_variable): Use
3253 coop_condition_variable_wait_mutex.
3255 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
3256 Definitions moved to coop-defs.h.
3258 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3259 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3260 scm_cond_destroy): New C interface to mutecis and cond vars.
3262 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3264 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3266 * iselect.c: Now several threads can wait on the same file
3267 descriptor. The behaviour is compatible with OS select: All
3268 threads waiting for the fd return with the same status.
3270 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3272 * coop-threads.c, threads.h (scm_spawn_thread): New function.
3273 Can spawn a thread from application C code.
3275 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3277 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3278 gh_doubles2scm): New functions.
3280 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3282 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3283 commented-out version of gh_eval_str()
3285 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3287 * socket.c (scm_bind): free soka after use.
3289 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3291 * stime.c (tzvar): new variable.
3292 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3293 avoid memory leaks when allocating.
3295 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3297 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3300 * gc.c, tags.h: Doc fixes.
3302 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3304 * eval.c (macro-eval!): Removed. This function was a design bug.
3305 It allowed memoized code to leak out to the scheme level. Most
3306 things that you could do with `macro-eval!' can be done with
3309 1997-12-20 Tim Pierce <twp@skepsis.com>
3311 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3312 scm_fgets now depends on ftell(3) to know how many bytes were
3315 1997-12-15 Tim Pierce <twp@skepsis.com>
3317 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3318 dealing with strings.
3320 1997-12-13 Tim Pierce <twp@skepsis.com>
3322 Make %read-line more suitable for implementing read-line efficiently.
3323 * ioext.c (scm_read_line): Strip the terminating newline from a
3324 string, and return a cons of the string and its terminator.
3326 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
3327 of the string that is read is stored in this memory location.
3328 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
3329 * genio.c, genio.h (scm_do_read_line): Update caller.
3330 * ports.h (scm_ptobfuns): Update typedef.
3331 * fports.c (scm_fptob, scm_pipob): Update struct.
3333 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3335 * filesys.c (set_element): Return file descriptor.
3336 (fill_select_type): Return the highest file descriptor.
3337 (scm_select): Tell select about the highest file descriptor. On
3338 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
3339 Therefore the extra overhead for calculating the maximum fd seems
3340 to be more than compensated. Is this correct? In any case,
3341 scm_internal_select will be much faster with this info.
3342 (scm_select, fill_select_type, set_element): Don't accept any kind
3343 of object in the file descriptor list or vector.
3345 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3347 * iselect.c (finalize_fd_sets): Bugfix.
3349 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3351 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
3352 when using scm_internal_select (since we might switch to another
3355 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3357 * simpos.c (scm_system): always define: use sysmissing if not
3358 available. Check for HAVE_SYSTEM instead of _Windows (does
3359 Windows lack system or does it have an unusable one?).
3360 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
3361 Let the argument be optional: if not supplied, call system(NULL).
3363 * ports.c (scm_close_port): relax the type check from OPPORTP to
3364 PORTP; closing a closed port is allowed.
3366 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
3368 * fports.c (scm_fgets): Return if the last char in a chunk is
3369 newline. When fgets returns a string whose length is `size-1', it
3370 is ambiguous whether a whole line was retrieved, so we must check
3371 explicitly whether a line terminator is present.
3373 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3375 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
3376 before taking the CDR. (Thanks to Harald Meland.)
3378 * filesys.c (scm_stat): Slightly optimized.
3380 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
3382 * ports.c (scm_close_port): Make sure the port is open before
3385 * guile-snarf.in: Pass args through to gcc in a way that preserves
3386 whitespace boundaries. (Thanks to Greg Badros.)
3388 1997-12-02 Tim Pierce <twp@skepsis.com>
3390 * stacks.c (scm_frame_procedure): Reverse the logic in the return
3391 statement. (Thanks to Doug Evans for pointing this out.)
3393 1997-12-01 Tim Pierce <twp@skepsis.com>
3395 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
3397 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
3399 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
3400 errno macro expansion of this field name. (errno is a C
3401 preprocessor macro on some systems.)
3403 1997-11-29 Tim Pierce <twp@skepsis.com>
3405 * iselect.c: Doc fix.
3407 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
3409 * init.c (scm_start_stack): Removed initialization of
3410 scm_the_last_stack_var.
3412 * backtrace.h: Declare scm_the_last_stack_var.
3414 * backtrace.c: Define scm_the_last_stack_var.
3416 * root.c (mark_root): Don't mark the_last_stack_var.
3418 * root.h (scm_root_state): Removed the_last_stack_var.
3420 * throw.c: Added #include "fluids.h"
3421 (ss_handler): `the-last-stack' is now a fluid.
3423 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
3424 --> the_last_stack_fluid.
3426 * backtrace.c: Added #include "fluids.h"
3427 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
3428 (scm_backtrace): `the-last-stack' is now a fluid.
3430 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
3431 after scm_init_fluids.
3433 1997-11-28 Tim Pierce <twp@skepsis.com>
3435 * iselect.c: #ifdef USE_THREADS around thread-related includes.
3437 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
3438 DLSYM_ADDS_USCORE to decide whether to add an underscore.
3440 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3442 * iselect.c (coop_next_runnable_thread,
3443 coop_wait_for_runnable_thread): Disable interrupts so that no
3444 async is executed before a potential error_revive.
3445 (scm_internal_select): Disable interrupts during the parts of the
3446 code which manipulate the sleep queue and the file descriptors.
3448 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3450 * Makefile.am: Added iselect.c and iselect.h.
3452 * coop.c (coop_qinit): Initialize fields used by
3453 scm_internal_select.
3454 (coop_qget, coop_qget, coop_tmp_queue): Made global.
3455 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
3456 replacement in iselect.c.
3457 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
3458 coop_join): If GUILE_ISELECT enabled, use
3459 coop_wait_for_runnable_thread instead of
3460 coop_next_runnable_thread.
3461 (usleep, sleep): New replacements for system functions if
3462 GUILE_ISELECT is enabled.
3464 * coop-threads.h: Declare coop_wait_for_runnable_thread.
3466 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
3468 * filesys.c: Added #include "iselect.h". Moved FD-macros to
3469 iselect.h. Implement Scheme level `select' using
3470 scm_internal_select. (See NEWS.)
3472 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
3474 * init.c: Call scm_init_iselect.
3476 * iselect.h, iselect.c: New files. Implements
3477 scm_internal_select. (See NEWS.)
3479 1997-11-27 Tim Pierce <twp@skepsis.com>
3481 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
3482 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
3483 and scm_must_free, since ultimately the string returned will be copied
3484 by scm_makfrom0str anyway. Also, read any characters that may have
3485 been pushed onto the port with scm_ungetc.
3486 * ports.c (scm_generic_fgets): Same as for scm_fgets.
3487 * ioext.c (scm_read_line): Free string after Guilifying it.
3488 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
3490 1997-11-26 Anthony Green <green@hoser.cygnus.com>
3492 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
3494 * gh.h: Safely wrap prototypes for c++ usage.
3496 1997-11-25 Mark Galassi <rosalia@cygnus.com>
3498 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
3499 gh_repl (argc, argv).
3501 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
3503 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
3504 and to invoke scm_shell().
3505 (gh_launch_pad): took out the loading of boot-9.scm from here,
3506 since it is probably best to let the user control that. In fact,
3507 gh_repl() now invokes scm_shell() which does that.
3509 1997-11-23 Mark Galassi <rosalia@cygnus.com>
3511 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
3514 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
3516 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
3517 yesterday's underscore patch. (Thanks to Marius Vollmer for
3520 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
3522 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
3523 DLSYM_ADDS_USCORE is not defined.
3525 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
3527 * gh_data.c (gh_uniform_vector_length):
3528 (gh_uniform_vector_ref): started implementing the uniform types in
3531 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
3533 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
3534 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
3536 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
3538 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
3539 configure.in was changed).
3541 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
3543 * Makefile.am (modinclude_HEADERS): Include readline.h here.
3544 * Makefile.in: Regenerated.
3546 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
3548 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
3549 OPORT is an `open' port, not an output port.
3551 * filesys.c (scm_close, set_element, get_element, scm_chown,
3552 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
3553 SCM_COERCE_OUTPORT to cope with the printstate/port magic.

3573 Minor problems with substring-related tag changes.
3574 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
3575 exactly what we want to leave in to detect substrings.
3576 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
3577 * tags.h: Fix diagrams and comments describing the S tag bit;
3578 remove vestigial remarks about the D tag bit.

3580 * strings.c: Formatting tweaks.
3582 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment

3592 (scm_boot_guile_1): Call scm_init_readline, if we have it.
3593 * Makefile.am (libguile_la_SOURCES): Include readline.c.
3594 * Makefile.in: Regenerated.
3595 * scmconfig.h.in: Regenerated, after change to ../configure.
3597 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3599 * gh.h: gh_vector_set -> gh_vector_set_x
3601 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3603 * gh_data.c (gh_vector_set_x): changed name to make it consistent
3604 with the ! -> _x mapping when going from Scheme to C.
3606 1997-10-19 Mark Galassi <rosalia@cygnus.com>
3608 * gh.h (gh_reverse):
3616 (gh_assoc): added these gh_ functions implemented as macros.
3618 * gh_predicates.c (gh_null_p):
3619 (gh_string_equal_p): added these two missing predicates.
3621 * gh_list.c (gh_append):
3626 (gh_set_cdr_x): added these routines as I go through and try to
3627 complete the picture R4RS functions that should be mirrored in the
3630 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3632 * tags.h (scm_tc7_substring): Changed the comment and code to
3633 conform with the changes below. Folks! We have suddenly two new
3634 free tc7 codes!!! Jummy, jummy!

3667 Don't include "mbstrings.h".
3668 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
3669 (SCM_SYMBOL_SLOTS): Define as 4.

3691 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
3692 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
3694 1997-10-12 Mark Galassi <rosalia@cygnus.com>
3696 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
3698 * gh_test_c.c (c_vector_test): some improvements on the vector
3701 * gh.h (gh_vector): this used to exist but do the wrong thing.
3702 Now it (almost) does the right thing, though it takes a list
3703 instead of the individual arguments. I need to see how it could
3705 (gh_list_to_vector): added this function as a macro. Corresponds
3706 to Scheme's (list->vector ...).
3707 (gh_vector_to_list): added this function as a macro. Corresponds
3708 to Scheme's (vector->list ...).
3710 * gh_data.c (gh_vector_ref): renamed from gh_vref to
3711 gh_vector_ref, so that it resembles the Scheme routines more.
3712 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
3713 resembles the Scheme routines more.
3714 (gh_make_vector): this used to be (stupidly) called gh_vector().
3715 This is the right name, since it does the same thing as the Scheme
3716 (make-vector ...) procedure.
3718 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
3720 * ports.h: #include "libguile/print.h"
3722 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
3723 Some indentation fixes.
3725 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
3726 longer a user field; New field: class_flags.
3728 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
3730 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
3732 * gh_data.c (gh_bool2scm): new function which replaces
3733 gh_int2scmb(), which is now tagged as obsolete.
3735 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
3737 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
3738 macros should by convention not test for NIMPness.)
3739 (SCM_COERCE_OPORT): Adjust indentation.
3741 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
3742 SCM_NIMP test before SCM_PRINT_STATE_P.
3744 * struct.c, struct.h, gc.c: Renamed:
3745 scm_struct_i_layout --> scm_vtable_index_layout
3746 scm_struct_i_vcell --> scm_vtable_index_vcell
3747 scm_struct_i_vtable --> scm_vtable_index_vtable
3748 scm_struct_i_printer --> scm_vtable_index_printer
3749 scm_struct_i_vtable_offset --> scm_vtable_offset_user
3751 * struct.c (scm_print_struct): Use new printer slot; Default
3752 printing: Also output hex code of vtable so that type identity
3753 will be indicated as well.
3754 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
3755 Removed struct_printer_var; Removed struct-vtable-offset;
3756 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
3757 vtable-offset-user): New constants.
3759 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
3760 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
3761 If this slot contains a procedure, use that to print structures of
3762 the type represented by this vtable.
3764 * print.c (scm_iprin1): Don't print arguments of macro
3765 transformers. (They are always: exp env.); Bugfix: Unmemoize
3766 transformer source with correct environment.
3768 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
3770 Streamlining of call-with-dynamic-root:
3772 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
3773 there is now only one catch.
3774 (cwdr_outer_body): Removed.
3775 (cwdr_handler): New function.
3776 (scm_internal_cwdr): New function to perform the function of cwdr
3777 but take args that are more useful to C code. Also, the handler
3778 is now invoked *outside* of the new dynamic root, like the docs
3779 say. We no longer have to catch absolutely all errors, the caller
3780 is responsible for using a handler that does not throw, if he
3782 (cwdr): Reimplemented in terms of scm_internal_cwdr.
3783 * root.h (scm_internal_cwdr): New prototype.
3785 Even more but risky streamlining:
3787 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
3788 allocation of the jumpbuf of a root continuation. The changes
3789 below are controlled by it. They are now deactivated.
3790 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
3791 the JMPBUF of the scm_rootcont to NULL before returning.
3793 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
3794 when they are non-NULL.
3795 (scm_gc_mark): Likewise, mark only when non-NULL.
3797 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
3798 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
3800 * gc.c (scm_done_malloc): New function.
3801 gc.h (scm_done_malloc): New prototype.
3803 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
3804 (struct scm_print_state) [revealed]: New field.

3806 type checking purposes.
3807 (scm_valid_oport_value_p): New prototype.
3809 * print.c (scm_valid_oport_value_p): New function to check whether
3810 a certain value is acceptable as a port argument.
3811 (scm_print_state_vtable): New variable.
3812 (scm_free_print_state): Set `revealed' field to false.
3813 (scm_iprin1): Call user supplied closure printer with
3814 scm_printer_apply. Print in the traditional way when there isn't
3815 one or when it returns #f.
3816 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
3817 Accept a port/print-state pair in addition to just a port.
3818 (scm_prin1): Don't return the print_state to the pool when it has
3820 (scm_printer_apply): Set `revealed' field of print_state to true.
3821 (scm_init_print): Set scm_print_state_vtable.
3822 (print_state_fluid, print_state_fluid_num): Removed.
3824 * throw.h (scm_handle_by_proc_catching_all): New prototype
3825 throw.c (scm_handle_by_proc_catching_all): New function
3827 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
3829 * Makefile.in: Regenerated with automake 1.2c.
3831 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
3833 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
3834 was looping endlessly.
3836 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
3838 * strports.c (scm_eval_string): Don't close the port.
3840 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
3841 former returns a nice normal integer. (Thanks to Daniel
3844 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
3846 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
3847 makefile variable as a build parameter called LIBS. The
3848 build-guile program will use this, for the time being.
3849 * Makefile.in: Regenerated.
3851 Thanks to Shiro Kawai:
3852 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
3853 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
3856 * Makefile.in: Regenerated with automake 1.2a.
3858 * script.c (scm_compile_shell_switches): If we hit the -c or --
3859 arguments, don't set the car of (command-line) to scm_usage_name,
3860 the prettified name of the guile executable; give it the full
3861 path, the way shells usually handle $0.
3863 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3865 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
3866 Scheme-level name `array-map' and renamed `serial-array-map' to
3867 `serial-array-map!'.
3869 * backtrace.c: Introduced exception handlers which now enclose
3870 `display-error' and `display-backtrace' so that error reporting
3871 won't get into infinite loops if an error occurs during displaying
3872 of the error. This can very easily happen with user supplied
3873 print call-back routines.
3875 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3877 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
3878 the names `serial-array-map' and `array-map' should be removed.)
3880 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
3882 * init.c (scm_boot_guile_1): Added scm_init_objects ().
3883 Added #include "objects.h"
3885 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
3886 Add #include "feature.h".
3888 * Makefile.am (libguile_la_SOURCES): Added objects.c.
3889 (modinclude_HEADERS): Added objects.h.
3891 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
3892 This test is needed at many places in the code and should be
3893 abstracted. (Motivated by the need of this test in libguiletk.)
3895 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
3896 (scm_eval_string), load.c (scm_primitive_load,
3897 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
3898 Use SCM_EOF_OBJECT_P.
3900 * eval.c (scm_init_eval): Add feature `delay'.
3902 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3904 * scmhob.h: Removed.
3906 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3908 * list.h (SCM_LISTn): New macros. Make list creation in C code
3909 prettier. The idea comes from STk.
3911 * sequences.h, sequences.c, append.h, append.c: Removed. These
3912 files implemented non-R4RS operations which would encourage
3913 non-portable programming style and less easy-to-read code.
3915 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
3918 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
3919 sequences.h, #include append.h.
3921 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
3924 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
3926 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
3928 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
3930 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3932 * eval.c: Added #include "objects.h"
3934 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
3937 * smob.c (scm_smob_prehistory): Create two objectsmobs with
3938 adjacent smob numbers.
3940 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3942 * procprop.h: Added declaration of scm_i_inner_name.
3944 * gsubr.c: New global symbol scm_i_inner_name.
3946 * debug.c (scm_procedure_name): Try procedure property
3947 `inner-name' if `name' fails.
3949 * print.c (scm_iprin1): Use scm_macro_name.
3951 * eval.c (scm_m_define): Give names to macros as well; Only the
3952 first top-level definition gives a procedure/macro a name.
3953 Otherwise confusing names can turn up in backtraces.
3954 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
3955 `name'; Give names to macros as well.
3957 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
3958 (scm_macro_transformer): Use SCM_CLOSUREP instead of
3961 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3963 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
3965 (prinmacro): Removed. The code has been moved/merged into print.c
3966 in order to decrease code redundancy. We want macros to print in
3967 a way equivalent to procedures, and it would be silly to duplicate
3968 the required code. (We don't want to maintain two places.)
3969 (macrosmob): Print field is now a NULL pointer.
3971 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
3972 scm_macro_transformer): New prototypes.
3973 (scm_tc16_macro): Declared.
3975 * print.c (scm_iprin1): Added code for printing of macros. Macros
3976 are now printed in a way equivalent to procedures.
3978 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
3980 * procs.h (scm_closure_p): Added declaration.
3982 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3984 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
3985 Shouldn't pass "heap" as the subr name.
3987 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
3989 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
3990 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
3991 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
3992 gh_equal_p): Use SCM_NFALSEP, instead of testing against
3993 SCM_BOOL_T. Any non-false value is true.
3995 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3997 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
3998 scm_gensym): Added prototypes.
4000 * symbols.c (scm_gensym): New function. This will speed up
4001 certain types of applications (such as macro systems) which
4002 generate lots of symbols.
4004 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4006 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
4008 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
4010 * unif.c (scm_shap2ra): tighten the checking of the array dimension
4011 specifier, since (2) or (2 . 3) would cause SEGV.
4012 (scm_transpose_array): more argument checking fixes.
4014 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
4016 * Makefile.in: Regenerated.
4018 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
4020 * Makefile.in: Regenerated, so it uses "tar", not "gtar".

4047 * list.c (scm_list_append_x): Allow non-pair as last argument.
4048 This is consistent with the R4RS append and is probably the
4049 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
4051 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4053 * stime.h: prototype for scm_times.

4071 third argument is now optional.
4073 * posix.c (scm_execl, scm_execlp): make the filename argument
4074 compulsory, since omitting it causes SEGV.
4075 (scm_sync): return unspecified instead of #f.
4076 (scm_execle): new procedure.
4077 (environ_list_to_c): new procedure.
4078 (scm_environ): use environ_list_to_c. disable interrupts.
4079 (scm_convert_exec_args): take pos and subr arguments and
4080 improve error checking.

4084 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
4085 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
4086 argument to SCM_ASSERT. Furthermore, the name of the function
4087 should be passed as first argument when signalling
4088 SCM_WNA. (Thanks to Thomas Morgan)
4090 * gsubr.c (scm_gsubr_apply): From Radey Shouman
4091 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
4092 dispatches on the number of actual args has a default case
4093 reporting an internal error. This is a vestige from a version
4094 that mallocated a SCM vector to hold the arguments. In the
4095 current version this check is too late: if it ever happens we will
4096 have already overstepped the bounds of the array.
4098 Also, the patch [...] adds a check for too many actual arguments."
4100 mdj: Removed check for "internal programming error".
4102 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4104 * gh_io.c (gh_write): New function.
4106 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
4107 throw.c (scm_internal_stack_catch): New sibling to the other catch

4119 fold in the functionality of scm_primitive_dup.
4120 (scm_primitive_dup): deleted.
4122 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
4124 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
4125 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
4126 ultrix are defined. Use setvbuf instead of setbuf.
4127 (scm_setvbuf): new procedure.
4128 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
4129 (scm_setfileno): moved from ioext.c.

4143 (scm_init_print): Initialize them.
4144 (scm_iprin): If print_state_fluid carries a print_state, use that
4145 instead of creating a new one.

4147 definitions to help with calling printer functions written in
4149 * print.h (scm_printer_apply): New prototype.

4165 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4167 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
4168 to a list of length zero correctly.
4170 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

4188 * ioext.c (scm_primitive_dup2): return the new file descriptor
4189 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
4191 (scm_fdopen): bug fix: don't try to make port unbuffered until its
4192 stream has been set.
4193 (scm_duplicate_port): deleted, there's now an implementation in

4246 data. (dynl_smob): Use it.
4247 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
4248 the dynamic object data below the linking of the object to avoid
4249 memory leak when the linking code throws an error. Now the code
4250 leaks a whole dynamically linked library when must_malloc throws,
4251 but that should be much less likely.
4253 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
4255 Changes to compile under gnu-win32, from Marcus Daniels:

4293 think this is left over from the (eq? '() #f) days.
4295 * read.c (recsexpr): Give this a dummy definition if
4296 DEBUG_EXTENSIONS isn't #defined.
4298 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
4300 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

4326 turn off REG_EXTENDED.
4327 (scm_init_regex_posix): New regexp/basic symbol.
4328 (REG_BASIC): #define this if it is not already present.

4375 (cwdr_outer_body): New function, to establish the user's handler,
4376 and pass control to cwdr_inner_body.

4388 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
4389 the feeling that real thread systems will not need this...
4391 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
4393 Try to detect when people are using one version of libguile and a

4405 primitive definitions under their Scheme names.
4407 * Makefile.am (libguile_la_LDFLAGS): Update library version to
4408 1:2. Helps avoid confusion between installed and uninstalled libs.
4410 * scmconfig.h.in: Regenerated. (Needed after June 3 change to

4421 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
4423 * ports.h: new prototype.

4433 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
4435 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
4436 argument plain char *.

4439 * tag.c (scm_tag): Remove unreachable statement.
4440 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
4441 top of the word, it should be unsigned.
4443 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
4444 is defined, to avoid warnings; it's only used in the
4445 conflict-checking code. Which might go away anyway.
4446 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
4447 conditionals; put the label definition in an #if too, to stifle
4450 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
4451 ChangeLog-threads in the distribution.
4452 * Makefile.in: Regenerated.

4462 * load.c (scm_init_load_path): Append $(datadir)/guile to

4482 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
4484 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
4486 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
4489 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
4491 * eval.c (scm_lookupcar1): New procedure to cope with a race
4492 condition during lookup (when using threads).
4493 (scm_lookupcar): Implement in terms of scm_lookupcar1.
4494 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
4497 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
4499 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
4500 supplied. (Change from Tim Pierce.)
4502 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
4504 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
4505 23:47:01 1997" changelog: Slots are now initialized with `#f' by
4506 default and not `()'. `#f' is the canonical non-value in Scheme,
4509 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4511 * struct.c (struct_printer): New variable that holds a handle on
4512 the Scheme variable *struct-printer*. This variable can be set by
4513 Scheme code to override the printing of structures.
4514 (scm_print_struct): If struct_printer is set, call it. If it is
4515 not set, or returns #f, print the structure in the old fashion.
4516 Include "eval.h" for scm_apply.
4518 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
4520 * struct.c (scm_struct_ref, scm_struct_set_x): Use
4521 scm_struct_i_n_words to get the number of fields, not
4522 -scm_struct_n_extra_words.
4524 On the route to fancier struct printing:
4525 * struct.c (scm_print_struct): New function to print a structure.
4526 Include "genio.h" to support it. This function doesn't do
4527 anything interesting right now, but I think it should be here
4529 * struct.h: Include "print.h" and add prototype for
4531 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
4532 print structures ourself.
4534 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4536 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
4537 before applying the handler in case it doesn't return.
4539 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
4541 * scmsigs.h, async.h: updated.
4543 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
4546 * posix.c (scm_uname): interpret only negative values as an error.
4547 Solaris normally returns a positive value.
4549 * script.c (scm_compile_shell_switches): if we are not going into
4550 an interactive repl, set scm_mask_ints to zero so that asyncs can
4553 * simpos.c (scm_system): don't ignore/unignore signals around
4556 * posix.c (scm_open_pipe): don't ignore/unignore signals around
4559 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
4560 done in boot-9.scm instead.
4562 * scmsigs.c, async.c: Major rewriting of signal handling code.
4563 (scm_sigaction): new procedure.
4564 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
4566 (scm_raise): return unspecified, throw error on failure.
4568 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4570 * regex-posix.c (scm_init_regex_posix): Register the "regex"
4571 feature, to help boot-9.scm decide whether to import the regex
4574 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
4576 * eval.c: Include scmconfig.h at the beginning of the file so that
4577 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
4580 * regex-posix.c: #include "_scm.h" before conditionally #including
4581 <regex.h>; the former defines HAVE_REGCOMP.
4583 * regex-posix.c: #include <regex.h> conditionally, so the file is
4584 CPP'able (for dependency scanning) even on systems that don't have
4587 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
4589 Add new R4RS-compliant syntax for keywords.
4590 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
4591 regardless of the setting of the `keywords' read option.
4592 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
4593 can be re-read no matter what the setting of the `keywords' read
4596 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
4598 Add support for POSIX regular expressions.
4600 * regex-posix.c, regex-posix.h: New files. (Some code
4601 is taken liberally from rx/rgx.c in the old Guile dist.)
4603 * init.c: Include regex-posix.h.
4604 (scm_boot_guile_1): Call scm_init_regex_posix.
4606 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
4607 Add regex-posix.[ch] sources.
4608 * Makefile.in: Regenerated.
4610 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
4611 to do this automatically? It didn't for me, bleh.)
4613 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
4615 * fports.c (print_pipe_port): New function.
4616 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
4617 latter doesn't even take the right arguments.
4619 * Makefile.am: Increment shared lib revision number. I think
4620 sometimes the uninstalled Guile finds the installed shared lib;
4621 Gord says doing this might help. As things turned out, I can't
4622 say whether it does.
4623 * Makefile.in: Regenerated.
4625 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
4626 passing it as the closure argument to scm_boot_guile. (Bill
4629 * ports.c (print_void_port, putc_void_port, puts_void_port,
4630 write_void_port, flush_void_port, getc_void_port, close_void_port,
4631 noop0): Use ANSI prototypes instead of K&R declarations, so the
4632 initialization of void_port_ptob gets aggressively type-checked.
4633 Fix arguments of print_void_port and write_void_port. (Bill

4667 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
4669 * script.c (scm_find_executable): Use prototype-style definition
4670 here; apparently it's not quite right to have const in a prototype
4671 and then use a K&R declaration. I wonder if stuff like this will
4672 go away if we compile with -Wrequire-prototypes, or whatever that
4673 is... (Bernard URBAN)
4675 * scmhob.h: New text from Bernard URBAN.
4677 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4679 * script.c: Don't #define const on hpux. Configure takes care of
4680 this. (Thanks to Larry Schwimmer.)
4682 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
4683 decide whether to #include <unistd.h>, instead of listing a bunch
4684 of systems. Don't #include stdio twice. Removed dyked-out
4685 definition of scm_find_impl_file.
4687 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
4689 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
4690 library version info to 1:0.
4691 * Makefile.in: Regenerated.
4693 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

4697 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
4698 throw.c: Update copyright years; these files have been worked on
4699 significantly in 1997, but only had copyright years for 1996.
4700 Also, change name of copyright holder on some from Mikael
4701 Djurfeldt to Free Software Foundation; he has signed papers
4702 assigning the changes to the FSF.
4704 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
4705 reason not to give the user the option.
4707 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
4708 Return #f on end-of-file when scanning table (i.e. when called
4709 with no arguments). Try to catch errors, when we can.
4710 * posix.c (scm_getgrgid, scm_getpwuid): Same.
4712 * script.h (scm_shell_usage, scm_compile_shell_switches): New
4713 external declarations. These are useful.
4715 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
4717 * posix.c: don't include <sys/select.h> or define macros for
4718 select, since they were not used in this file.
4720 * filesys.c (scm_select): make the fifth parameter microseconds,
4721 not milliseconds. let the fourth parameter be either a real value
4722 or an integer or #f. The first, second and third arguments can
4723 now be vectors: the type of the corresponding return set will be
4725 (set_element, get_element): new static procedures.
4727 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
4729 * strports.c (scm_eval_string): New function.
4730 (scm_eval_0str): Trivially re-implemented in terms of
4732 * strports.h (scm_eval_string): New extern decl.
4734 * net_db.c (h_errno): Add extern decl for this.
4736 * fports.c (local_pclose): New function.
4737 (scm_pipob): Use it in the initializer here.
4740 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
4741 Use a meaningful error message when signalling an error. For
4742 this, scm_gethost must check h_errno rather than errno.
4744 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
4746 * Makefile.in: Regenerated, using automake-1.1p.
4748 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
4750 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
4751 not SCM_UNSPECIFIED.
4753 * script.c (scm_compile_shell_switches): don't append (quit) if
4755 (scm_shell): call scm_exit_status and exit on the result of the
4758 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
4760 Ensure that shared substrings are handled properly when passed to
4761 a system call or other foreign function. Many thanks to Tim
4763 * symbols.h (SCM_COERCE_SUBSTR): new macro.
4764 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
4765 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
4766 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
4767 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
4768 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
4769 (scm_display_error_message): use RO macros when strings may be RO.
4770 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
4771 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
4772 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

4776 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
4777 scm_strftime), vports.c (scm_make_soft_port): use
4778 SCM_COERCE_SUBSTR to make sure shared substrings are
4781 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
4783 * error.c (scm_error): Add newline to error message.
4785 * init.c (scm_init_standard_ports): Doc fix.
4787 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4789 * dynl-shl.c: Completely replaced with new code from Bernard
4792 * script.c (scm_ice_9_already_loaded): New variable.
4793 (scm_compile_shell_switches): Use it.
4795 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4797 * filesys.c (scm_input_waiting_p): add missing third argument to
4800 * stime.c (scm_localtime): copy the result of localtime before
4801 calling gmtime in case they share a buffer.
4802 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
4805 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
4807 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
4809 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
4811 * Makefile.am (check-local): New target, which causes 'make check'
4812 to run gh_test_c and gh_test_repl, with some trivial input.
4813 * Makefile.in: Rgnrtd.
4815 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
4817 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
4820 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
4822 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
4823 sure how this was supposed to work.
4824 (scm_async_click): don't send SCM_TICK_SIGNAL.
4825 (scm_init_async): don't initialize %tick-thunk.
4827 * the following change doesn't affect the Scheme interface:
4828 gc-thunk is called at the end of garbage collection. however it's
4829 no longer implemented by pretending it's a signal.
4831 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
4832 system async corresponding to scm_gc_thunk.
4833 * async.h: declare scm_gc_async.
4834 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
4835 gc-thunk directly, instead of going through a signal handler.
4836 (scm_gc_async): new variable, points to the GC system-async.
4837 (scm_init_async): save the GC async as scm_gc_async instead
4838 of using system_signal_asyncs.
4839 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
4841 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
4843 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
4844 Don't screw up if we're interrupted.
4845 * Makefile.in: Regeneradet.
4847 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
4849 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
4851 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
4852 we're not using AM_INIT_GUILE_MODULE any more.
4853 * Makefile.in: Reneregated.
4855 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
4857 Functions for finding variable bindings, grace à Tim Pierce.
4858 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
4859 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
4861 Get 'make dist' to work again.
4862 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
4863 * Makefile.in: Regenerated, like a surry without a fringe on top.
4865 Changes for reduced Guile distribution: one configure script,
4867 * configure.in, configure: Removed.
4868 * acconfig.h, acinclude.m4: Moved to parent directory, where the
4869 real configure script lives.
4870 * Makefile.in, scmconfig.h.in: Regenerated.
4872 * init.c: #include "script.h", to get prototype for script.c's
4875 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
4877 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
4878 scm_must_malloc, not raw malloc.
4880 * script.c (scm_compile_shell_switches): Dyke out debugging output
4883 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4885 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
4887 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
4888 system has them. Hope this is safe. Previously
4889 sys/timeb.h was included if HAVE_FTIME was defined or if
4890 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
4891 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
4893 * ioext.c (scm_setfileno): add missing third argument to
4894 scm_misc_error call.
4896 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
4898 * eq.c (scm_equal_p): Correctly compare strings of different
4899 varieties. (Thanks to Tim Pierce.)
4901 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
4903 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
4904 #! block comment must occur on a line all by itself.
4906 Move most of the guts of shell command processing into libguile,
4907 so guile.c can be very small (and eventuallly auto-generated. (I
4908 mean, generated mechanically, not self-generated. Hmm.))
4909 * guile.c, script.c, script.h: New source files.
4910 * init.c (scm_boot_guile_1): Call scm_init_script.
4911 * libguile.h: #include "script.h".
4912 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
4913 targets, for new executable.
4914 (libguile_la_SOURCES): Mention script.c.
4915 (modinclude_HEADERS): Add script.h.
4916 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
4917 not dynamic linking is enabled. This is because we're generating
4918 executables now. Move CY_AC_WITH_THREADS call after those, so the
4919 values of cy_cv_threads_libs captures the libs chosen above.
4920 * Makefile.in, configure, aclocal.m4: Regenerated.
4922 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
4923 We don't maintain this interface any more, and it just confuses
4926 * alloca.c: #include <scmconfig.h>, not <config.h>.
4927 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
4928 it'll get included in disties.
4930 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
4932 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
4933 be distributed, because they confuse people.

4939 OpenBSD by default).
4940 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
4941 * configure, scmconfig.h.in: Regenerated.
4943 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
4945 * backtrace.c (scm_backtrace): Split message string across
4946 newlines properly. GCC is more tolerant of this than other

4951 Merge threads directory into libguile.
4952 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
4953 threads.h: New source files.

4959 coop-threads.c.cygnus, coop-threads.h.cygnus.
4960 * configure.in: If we're using threads, include threads.o in
4962 * _scm.h, libguile.h: threads.h lives in this directory now.
4963 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
4964 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
4965 currently used, but brought along for information's sake.
4966 * ChangeLog-threads: log from old 'threads' directory.
4967 * Makefile.in, configure: Rebuilt.
4969 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
4971 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not

4982 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
4984 (EXTRA_libguile_la_SOURCES): ... here.
4985 (pkginclude_HEADERS): Add variable, to get gh.h installed.
4986 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
4987 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
4988 New variables, describing how to build the gh test programs.
4989 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
4990 build the test programs, and we probably should have been linking
4991 libguile.la against them all along, to support AIX shared libs.
4992 Add cflags for threads to CFLAGS; add libs for threads to new
4993 variable THREAD_LIBS, used in Makefile.am.
4994 * ChangeLog-gh: log from old `gh' subdirectory.
4995 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
4997 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
4999 * acconfig.h: Undo change of Apr 9; including the definition of
5000 PACKAGE in the guile headers conflicts with applications' own
5002 * scmconfig.h.in: Regenerated.

5013 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
5015 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
5016 have S_IFSOCK. This is the case under Ultrix.
5018 * posix.c (scm_status_exit_val, scm_status_exit_val,
5019 scm_status_term_sig, scm_status_stop_sig): Modified to work with
5020 Ultrix versions of WIFSTOPPED, etc., which assume that their
5021 arguments are lvalues (hmm).
5023 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5025 * eval.c: Doc fixes.
5027 * throw.c: Doc fixes; rearranged.
5029 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.

5033 * acconfig.h: Added entry for PACKAGE.
5034 * scmconfig.h.in: Regenerated.
5036 Changes to work with automake-1.1n, which has better libtool support.
5037 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5038 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
5040 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
5042 * Makefile.in: Rebuild.
5044 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5046 * stime.c (scm_mktime): take an optional zone argument.
5047 (scm_localtime): check putenv return value.
5048 (scm_strftime, scm_strptime): moved from posix.c. move #include
5050 stime.h, posix.h: update prototypes.
5051 (bdtime2c, setzone, restorezone): new static procedures.
5052 (scm_mktime, scm_strftime): use them.
5053 (scm_strftime): don't call mktime before strftime. Use
5054 filltime for return value.
5055 (filltime): convert NULL zname to #f.
5056 (scm_strptime): return a count of characters consumed, not
5057 the remaining string.
5059 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5061 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.

5066 * configure.in: add AC_STRUCT_TIMEZONE.
5068 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5070 * stime.c (scm_init_stime): don't define ticks/sec.
5071 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5072 return value problem and is still portable.)
5074 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5076 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
5077 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5078 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
5079 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
5080 cpp_err_symbols.c): Corresponding changes.
5081 * Makefile.in: Regenerated.
5083 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5085 * posix.c (scm_putenv): don't check HAVE_PUTENV.
5086 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
5087 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
5088 * putenv.c: new file, from sh-utils 1.12.
5090 * posix.c (scm_environ): use malloc in place of scm_must_malloc
5091 since allocation isn't for Scheme objects.
5092 (scm_putenv): copy strings before placing in the environment.
5094 * stime.c (scm_current_time): throw an error if time returns -1,
5095 instead of returning #f.
5096 (scm_get_internal_real_time, scm_get_internal_real_time): use
5097 scm_long2num for return value instead of SCM_MAKINUM.
5099 * stime.h: prototypes updated.
5101 * stime.c (scm_time_in_msec): apparently unused, deleted.
5103 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5105 * configure.in: check for gettimeofday.
5107 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
5108 which may be more usefully portable than a gettimeofday interface.
5110 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
5112 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
5114 * Makefile.in: Regenerated.
5116 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5118 * stime.c (filltime): recovered static procedure.
5119 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
5122 * posix.h: add prototype for scm_close_pipe, remove prototypes for
5123 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5125 * posix.c (scm_mknod): split the mode argument into type and perms
5126 arguments, like the extra fields returned by stat.
5128 * fports.c (scm_pipob): set the close, free and print procedures.
5129 (scm_close_pipe): new procedure.
5131 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5132 define them in boot-9.scm
5134 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5136 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5137 wan't defined. Don't include fd.h.
5139 * Previously fd.h was regenerated whenever configure was run,
5140 forcing a couple of files to be recompiled.
5142 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5143 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5144 Check for _fileno as well as _file.
5146 * ioext.c: don't fd.h.
5147 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5150 * Change the stratigy for getting information about errno
5151 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5152 generating lists of symbols during the build process, which will
5153 not always work, include comprehensive lists in the distribution.
5154 To help keep the lists up to date, the "check_signals" and
5155 "check_errnos" make targets can be used.
5157 * configure.in: don't check for a command to extract errno codes.
5158 * Makefile.am: update file lists, remove errnos.list and errnos.c
5159 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5160 check_errnos targets.
5161 (CLEANFILES): remove errnos.c and errnos.list, add
5162 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
5163 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
5164 * errnos.default: deleted.
5165 * cpp_signal.c: new file.
5166 * cpp_errno.c: renamed from errnos_get.c.
5167 * cpp_err_symbols, cpp_sig_symbols: new files.
5168 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
5169 * error.c (scm_init_error): #include cpp_err_symbols instead of
5171 * posix.c (scm_init_posix): don't intern signal symbols. #include
5174 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5176 * strop.c (scm_i_index): allow the lower bound to be equal to the
5177 length of the string, so a null string doesn't always give an error.
5179 * posix.h: new prototypes.
5180 * posix.c (scm_status_exit_val, scm_status_term_sig,
5181 scm_status_stop_sig): new functions, as in scsh. They break down
5182 process status values as returned by waitpid.
5184 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
5186 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
5187 configure doesn't know about it.
5189 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5191 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
5193 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
5194 which defines C variables with global linkage.
5196 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5198 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
5201 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
5203 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
5204 has time to check why this doesn't work well with continuations.
5206 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
5208 * Fix shell syntax error; some shells won't tolerate
5209 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
5211 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5213 * posix.c (scm_uname): throw an error if uname fails instead
5216 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
5218 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
5221 * async.c (scm_ints_disabled): definition moved from error.c.
5223 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5225 * acconfig.h: Removed PACKAGE.
5227 * scmconfig.h.in: Regenerated.
5229 * snarf.h: g++ says it's non-portable not to specify the first
5230 argument in a varargs declaration. I introduced the first
5231 argument by using preprocessor conditionals.
5233 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
5235 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
5236 (scm_freopen): use RO string macros for filename and modes.
5237 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
5239 * posix.c (scm_getgrgid): simplify conversion of name to C string.
5240 (scm_mknod): use RO string macros for path.
5242 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
5243 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
5245 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5246 use SCM_ROSTRINGP and SCM_ROCHARS.
5248 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5250 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
5253 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
5254 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
5255 support for byte vectors.
5257 * print.c (scm_iprin1): Limit number of vector elements printed
5258 according to pstate->length.
5260 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5262 * backtrace.c (scm_display_error_message): don't segv if message
5265 * error.h: prototype for scm_error_scm.
5267 * error.c (scm_error_scm): new procedure, reimplements scm-error
5268 in C and uses scm_error.
5270 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5272 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5273 pointer to the Scheme variable read-hash-procedures and intern it
5274 in scm_init_read. Modify scm_read_hash_extend and
5275 scm_get_hash_procedure to use the pointer.
5277 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5279 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5280 (SCM_KEYWORD_STYLE): defined.
5282 * read.c (scm_read_opts): add a keywords option. This isn't a
5283 boolean option, in case someone wants to add support for DSSSL
5285 Setup scm_keyword_prefix symbol.
5286 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5288 I've left keyword support disabled by default, since it doesn't
5289 seem to break the module system and it gives R4RS standard behaviour.
5290 It can be reactivated with (read-set! keywords 'prefix).
5292 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5294 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
5295 before constructing arbiter.
5297 * eval.c (scm_m_define): Bugfix: Check that the object is a
5298 closure before setting the procedure property!
5300 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
5302 * ports.c: Removed `ungetc-char-ready?'.
5304 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
5306 * read.c (scm_init_read): intitialise scm_read_hash_procedures
5307 (idea from Mikael: make it a pair so scm_permanent object only
5309 (scm_read_hash_extend): don't call scm_permanent_object.
5310 (ideas from Mikael): if chr is already in the list, replace its
5311 procedure instead of appending it again. If proc is #f, remove
5313 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5315 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
5317 * gdbint.c (gdb_read): update scm_lreadr usage.
5319 * load.h: update prototypes.
5321 * load.c (scm_primitive_load, scm_read_and_eval_x,
5322 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
5324 * read.h: add prototype for scm_read_hash_extend. Change args for
5327 * read.c (scm_read_hash_procedures): new variable.
5328 (scm_read_hash_extend): new procedure.
5329 (scm_get_hash_procedure): new procedure.
5330 (scm_lreadr): use scm_get_hash_procedure instead of an argument
5331 for extended # processing.
5332 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
5333 scm_read_token): remove case_i, sharp arguments. Change callers.
5335 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
5337 * read.h (SCM_N_READ_OPTIONS): increase to 3.
5338 (SCM_CASE_INSENSITIVE_P): define.
5340 * read.c: add case-insensitive option to scm_read_opts.
5341 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
5342 to determine whether to convert symbol case.
5343 (default_case_i): definition removed.
5344 * read.c (scm_read_token): if case_i, downcase ic before doing
5347 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5349 * configure.in: Added configuration option `guile-debug'.
5350 Configure with --enable-guile-debug if you want a bunch of extra
5351 functions used for debugging when developing Guile.
5353 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
5355 * procs.c (make-cclo): New undocumented debugging procedure: Make
5356 compiled closure with internal procedure PROC and length LENGTH.
5357 Only compiled if GUILE_DEBUG is defined.
5359 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
5361 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
5363 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
5365 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
5366 with 3 or more args internally to the evaluator.
5368 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5370 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
5371 with 3 or more args internally to the evaluator. This is mainly
5372 because we don't want to pass entry and exit points of the
5373 debug support twice, but it also seems to increase the speed of
5374 the evaluator for such calls (e. g. (+ 1 2 3)).
5376 * backtrace.c (scm_display_application): New procedure:
5377 display-application; Set fancy printing parameters individually
5378 for different types of display (backtrace, error, application).
5379 (These should of course be customizable!)
5381 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
5382 clear the CHECK-flags.
5384 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5386 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5388 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5390 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
5391 from pairs with a GLOC in the car.
5393 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
5394 otherwise `symbol-hash' will behave badly.
5395 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
5396 we get segmentation fault!
5398 * symbols.c: Added #include "weaks.h". New functions:
5399 `builtin-bindings' and `builtin-weak-bindings'. (These will be
5400 moved to an extraneous library when we split libguile.)
5402 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5404 * filesys.c (scm_stat): stat now takes fport arguments too as
5405 documented in the manual.
5407 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5409 * debug.c (scm_single_step): Bugfix: Call continuation with
5410 scm_call_continuation instead of throwing to it.
5412 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
5414 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
5415 argument wasn't declared to be optional.
5417 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5419 * stime.c (scm_init_stime): Add feature "current-time".
5421 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5423 * throw.h: prototype for scm_exit_status.
5424 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
5425 args to derive an exit status. Allows (quit) to work from a
5427 (scm_exit_status): new function.
5430 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5432 * eval.c (scm_deval): Removed some old code.
5433 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
5435 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
5438 * symbols.c (msymbolize): Bugfix: Must initialize property list to
5441 * procs.c: Introduce the existent C function scm_thunk_p at the
5442 Scheme level as well.
5444 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5446 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
5447 used from C to easily lookup the value of a symbol in the current
5450 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5452 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
5453 scm_init_unif in this file. This will also fix a previous problem
5456 * configure.in: Added AM_MAINTAINER_MODE
5458 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5460 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
5463 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5465 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
5466 source files that are not always included in libguile but should
5467 have their dependencies calculated by automake. This variable is
5468 recognized by automake, no further magic is needed.
5469 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
5470 to deal exclusively with *.lo files, as it seems. The *.o files
5471 are built automatically when the corresponding *.lo file gets
5474 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
5476 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
5479 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
5481 * unif.c (scm_array_set_x): minor change to argument error checking.
5483 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
5485 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
5486 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
5487 They should only be included in the library at configure.in's
5489 (libguile_la_LDADD): Include the appropriate .lo files here.
5490 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
5491 so we know when to build them (and their .lo bretheren).
5492 * configure.in (LIBLOBJS): New substituted variable. We let
5493 configure decide which .o files to include in LIBOBJS, and then
5494 put the corresponding list of .lo files in LIBLOBJS. The latter
5495 is what we pass to libtool.
5496 * Makefile.in, configure: regenerated.
5498 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
5500 * symbols.c (scm_sysintern0): New function. Contains the core of
5501 old scm_sysintern but doesn't take a second value argument.
5502 (scm_sysintern): Now uses scm_sysintern0.
5503 (scm_sysintern_no_module_lookup): Renamed to
5504 scm_sysintern0_no_module_lookup and doesn't take a second value
5505 argument any longer.
5507 * symbols.h (scm_sysintern0: Added declaration.
5509 * options.c (scm_init_opts): Use scm_sysintern0 instead of
5510 scm_sysintern when interning option keys. Otherwise we risk
5511 destroying the values of already interned variables.
5513 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
5514 scheme-level boolean (use SCM_NFALSEP).
5516 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
5518 (scm_backtrace): New function. (C version of old function from
5519 boot-9.scm) Motivation: Make it possible to display backtraces
5520 without depending on boot-9.scm. (I'm uncertain if this
5521 motivation is good enough...)
5523 * root.h (scm_root_state): Add member the_last_stack_var.
5524 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
5526 * root.c (mark_root): Mark scm_the_last_stack_var.
5528 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
5531 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
5533 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
5534 1. mark_lazy_catch didn't mark the smob.
5535 2. Both functions above have standard variants:
5536 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
5537 free_lazy_catch --> scm_free0.
5539 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
5541 * throw.c (scm_internal_lazy_catch): New function.
5542 (scm_lazy_catch): Rewritten to use it.
5543 (scm_ithrow): Handle the new lazy catch representation.
5544 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
5545 that doesn't have a jmpbuf is a lazy catch clause.
5546 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
5547 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
5548 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
5550 (scm_init_throw): Register the new lazy-catch smob type.
5551 * throw.h (scm_internal_lazy_catch): decl for new function.
5553 * throw.c (scm_internal_catch): Doc fixes.
5555 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
5556 configure.in. Including this might cause problems if applications
5557 that link against libguile include their own copies of alloca, but
5558 if they're using autoconf, they should be adding libguile to LIBS
5559 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
5560 the copy in libguile, and things will be okay. (I think.)
5562 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5564 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
5566 strop.h: move prototypes too.
5568 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5570 * posix.c (scm_init_posix): don't intern EINTR since it's now done
5573 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
5574 etc. I deleted them from filesys.c long ago, but didn't
5575 notice they were here too (although ineffective since
5576 sys/stat.h wasn't included).
5578 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
5580 * eval.c: Don't define alloca in GCC case. gcc will automatically
5581 use __builtin_alloca if appropriate.
5583 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5585 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
5586 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
5587 that values of automatic variables are preserved. See comments
5588 for safe_setjmp for details.
5590 Change from Thomas Morgan:
5591 * variable.c: Include eq.h.
5592 (var_equal): New function.
5593 (variable_smob): Use var_equal as the discriminator for variables.
5595 * throw.c (s_throw): Remove extraneous declaration.
5597 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
5598 * eval.c: Add necessary CPP cruft to support that.
5599 * configure, Makefile.in, scmconfig.h.in: regenerated.
5601 Change from Thomas Morgan:
5602 * procprop.c (scm_procedure_properties): Convert the Scheme
5603 boolean returned by scm_procedure_p into a C boolean before using
5604 it as a condition for SCM_ASSERT.
5605 (scm_procedure_property): Likewise.
5607 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
5608 indications of Unixness.
5611 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5613 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
5615 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5617 * read.c (scm_lreadr): use scm_misc_error to improve one of the
5618 "unknown # object" error messages.
5620 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
5621 (scm_i_index) and declare it static. Add a 'direction' argument
5622 to indicate what way the search should go.
5623 (scm_i_index): throw out-of-range error instead of wrong-type-arg
5625 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
5626 strop.h: remove scm_i_index, scm_i_rindex prototypes.
5628 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5630 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
5632 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
5633 to avoid clash with various scsh forks.
5635 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
5637 The following two changes (ramap.c, throw.c) are motivated by the
5638 apparent unportability of forward declarations of static arrays of
5639 the form `static foo bar[];'.
5641 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
5642 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
5644 * throw.c (scm_throw): Moved above scm_ithrow.
5646 * options.h: Removed the extern declarations of scm_yes_sym and
5647 scm_no_sym since these are static.
5649 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5651 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
5653 * Makefile.am: remove AWK=@AWK@.
5654 Add a rule for generating errnos.list.
5655 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
5657 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
5658 don't extract errnos, just set a variable (avoids the
5659 need to recompile error.c just because configure is run.)
5661 * unif.h: update prototypes.
5662 * unif.c (scm_uniform_array_read,write): change the offset and
5663 length arguments to start and end, for consistency.
5665 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
5667 * ioext.h: update prototypes.
5668 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
5669 scm_read_line_x, it's a more general procedure using an
5670 interface from scsh. read-line and read-line! are now defined
5672 Note that the new read-line trims the terminator
5673 by default, previously it was appended to the returned string. An
5674 optional argument specifies how to process the terminator (scsh
5675 compatible). For the old behaviour: (read-line port 'concat).
5676 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
5677 returns a pair, but is converted to multiple values if the scsh
5680 socket.h: update prototypes.
5681 * socket.c (scm_recvfrom): for consistency with other procedures,
5682 take start and end as separate optional arguments.
5683 (scm_recv, scm_recvfrom): don't allow the second argument
5684 to be a size, only a buffer. Change the scheme names to
5685 recv! and recvfrom!. Don't return the buffer.
5687 * ioext.h, posix.h: move prototypes too.
5688 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
5689 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
5690 "read.h" and "unif.h".
5691 * ioext.c: include "chars.h"
5693 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
5695 * dynl.c: The dynamic linking and module registration functions
5696 are now defined even when dynamic linking is not available for the
5697 host system. Some of their functionality can be done without
5698 dynamic linking; when it's really needed, they throw errors.
5700 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
5702 * configure.in: Only define DYNAMIC_LINKING when one of the system
5703 dependent functions is detected.
5704 * dynl.c (scm_dynamic_func): New function to get the address of a
5705 function in a dynamic object.
5706 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
5707 produced by scm_dynamic_func as the thing to call.
5709 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
5711 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
5712 (scm_register_module_xxx, scm_registered_modules,
5713 scm_clear_registered_modules): New functions.
5715 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
5717 * symbols.c (scm_sysintern): Renamed to
5718 scm_sysintern_no_module_lookup.
5719 (scm_sysintern): New function to take the place of the old
5720 scm_sysintern. It uses the current toplevel lookup closure to give
5721 the symbol its value. This is a temporary hack to put packages
5722 like gtcltk into their own module.
5723 (scm_can_use_top_level_lookup_closure_var): New variable to tell
5724 us whether `scm_top_level_lookup_closure_var' has been initialized
5726 * eval.c (scm_init_eval): Set it.
5728 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5730 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
5731 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
5733 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
5735 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
5736 scm_sys_dup): deleted: FD capability will be added to other
5738 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
5739 scm_fd_free, fd_smob, scm_intern_fd.
5740 (scm_open): renamed from scm_sys_open. Return a port instead of
5741 an FD object. Make the mode argument optional.
5742 (scm_sys_create): deleted, it's just a special case of open.
5743 (scm_init_filesys): move interning of constants O_CREAT etc.,
5744 here (were previously using SCM_CONST_LONG macro).
5745 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
5747 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
5748 include "fports.h" and <stdio.h>
5749 (scm_stat, scm_select): don't support FD objects.
5751 * error.h: adjust scm_syserror_msg prototype.
5752 * error.c (scm_syserror_msg): take an extra argument for errno.
5753 Using the global value didn't always work, since it could be
5754 reset by procedure calls in the message or args arguments.
5756 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
5757 I don't understand why the check was there (and what about the
5760 * strop.c (scm_string_copy): allow shared substrings to be copied.
5762 * unif.h: corresponding change to prototypes.
5763 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
5764 recognize two new optional arguments: offset and length. Allow
5765 the port argument to be an integer (file descriptor, for scsh).
5766 Include <unistd.h> for "read" prototype.
5768 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5770 * socket.c: don't include filesys.h.
5772 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
5774 * Makefile.am: add AWK=@AWK@ (?)
5776 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
5778 Add a rule to generate errnos.c from errnos.
5779 * error.c (scm_init_error): include errnos.c.
5780 * errnos_cnvt.awk: new file, converts the list of errno codes to
5782 * errnos_get.c: new file.
5783 * errnos.default: new file, contains errnos to try if they can't
5784 be extracted from errno.h.
5785 * configure.in: if using GCC, try and extract errno codes from
5789 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
5791 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
5792 * Makefile.am: Made libguile into a libtool library.
5793 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
5794 Set libtool_libs to indicate that libguile is a libtool library.
5795 See guile/ChangeLog for details.
5796 * .cvsignore: ignore "*.lo", the libtool library objects.
5798 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5800 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
5801 use htons in getservbyport argument.
5803 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5805 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
5806 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
5809 * objprop.c (scm_object_property): No need to take the CDR of the
5810 value returned by scm_object_properties, since Aug 20 change.
5812 * configure.in: When checking for struct linger, #include
5813 <sys/types.h> as well as <sys/socket.h>. I've never known
5814 <sys/types.h> to cause any portability problems, and Solaris's
5815 <sys/socket.h> needs it.
5816 * configure: Rebuilt.
5818 I think the Sun compiler has chosen a perverse way to interpret
5819 ANSI declarations combined with K&R definitions. We'll
5820 appease it a little bit. But when it invades France, we fight.
5821 * print.c (scm_iprlist): Change 'tlr' argument to an int.
5822 * print.h (scm_iprlist): Here too.
5823 * numbers.c (scm_divbigdig): Change definition to match
5824 declaration in numbers.h.
5825 * unif.c (scm_makflo): Change definition to match declaration in
5828 * init.c (scm_boot_guile): Don't return the value of
5829 scm_boot_guile_1. This function doesn't return a value;
5830 scm_boot_guile_1 doesn't return a value (or return at all).
5832 * eval.c (unmemocopy): Add a semicolon to appease the Sun
5835 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
5836 compile. I have a feeling this function is a bad idea anyway ---
5837 one should always test for features, not systems.
5839 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
5840 semicolons. Only pure luck kept this from being noticed earlier.
5842 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
5844 * socket.c (scm_recvfrom): Added missing semicolon.
5846 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5848 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
5849 the buffer and start and end positions for scsh networking
5852 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
5854 * configure.in: Revert previous change to this file; the problem
5855 is due to transient automake weirdness.
5856 * configure: Rebuilt.
5858 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
5859 PLUGIN/guile.libs. configure generates the latter from the former.
5860 * Makefile.in: Rebuilt.
5862 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
5863 need this if we install scripts, like guile-snarf.
5864 * configure: Rebuilt.
5866 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5868 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
5870 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
5872 * socket.c (scm_addr_vector): fix faulty scm_listify.
5874 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
5876 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
5877 style block comment is no longer considered an error.
5879 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
5881 * PLUGIN/guile.libs.in: New file.
5882 * PLUGIN/guile.libs: Removed from repository.
5883 * configure.in: Create PLUGIN/guile.libs from
5884 PLUGIN/guile.libs.in. This is for including additonal libraries
5885 needed for dynamic linking.
5886 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
5887 instead of PLUGIN/guile.libs.
5889 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
5891 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
5893 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
5894 occurrences of the given element from the list, not just the
5895 first. This is how the Emacs Lisp functions behave, how the
5896 analogous Common Lisp functions behave, and (I believe) how the
5897 older Maclisp functions worked. I realize that this change may
5898 break code, but it seemed better to break it before the Guile
5901 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
5902 Their prototypes were already present in gc.h, but they weren't
5904 (scm_init_storage): Initialize scm_protects.
5905 * root.c (scm_protects): New element of scm_sys_protects.
5907 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
5909 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
5911 * libguile.h: Added #include "libguile/net_db.h".
5913 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
5914 30 change. That file is only meant for communication between the
5915 configuration process and load.c. If code linked against libguile
5916 wants to get at the paths mentioned in libpath.h, it can call
5917 functions declared in load.h.
5919 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5921 * libguile.h: Removed #include "libguile/fdsocket.h"
5923 * net_db.c: Added #include <sys/socket.h>.
5925 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
5927 * filesys.c (scm_input_waiting_p): use select in preference to
5928 FIONREAD, since the latter doesn't detect EOF.
5929 Throw error if neither select nor FIONREAD available.
5931 * socket.c (scm_connect): take a port, not a fd object.
5932 (scm_fill_sockaddr): throw an error if fam is not recognised.
5933 (scm_bind): use scm_fill_sockaddr.
5934 (scm_listen): take a port, not a fd object.
5935 (scm_accept): take and return a port. return #f in the car if
5936 address can't be got
5937 (scm_sock_fd_to_port): new procedure.
5938 (scm_socket): use scm_sock_fd_to_port.
5939 (scm_addr_vector): throw error if unrecognised address type.
5940 take an extra argument with the calling procedure name.
5941 (scm_getsockname): take a port. return #f if address can't be got.
5942 (scm_getpeername): take a port. return #f if address can't be got.
5943 (scm_recvfrom): take a port. return #f for address component if can't
5945 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
5946 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
5948 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
5950 * throw.c (scm_internal_catch): Make body funcs and handler funcs
5951 use separate data pointers, to allow them to be designed
5952 independently and reused.
5953 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
5954 Renamed from catch_body, catch_handler, and uncaught_throw; made
5956 (struct scm_catch_body_data): Renamed from catch_body_data; moved
5958 (scm_catch): Use the above.
5959 (scm_throw): Don't bother printing a message for an uncaught
5960 throw; we establish a default handler in init.
5961 * throw.h (scm_internal_catch): Prototype updated.
5962 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
5964 (struct scm_body_thunk_data): New structure, used as data
5965 argument to scm_body_thunk.
5966 * init.c (struct main_func_closure): New structure, packaging up
5967 the data to pass to the user's main function.
5968 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
5969 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
5970 scm_internal_catch to establish a catch-all handler, using
5971 scm_handle_by_message. This replaces the special-case code in
5973 (invoke_main_func): Body function for scm_internal_catch; invoke
5974 the user's main function, using the main_func_closure pointer to
5975 decide what to pass it.
5976 * root.c (struct cwdr_body_data): Remove handler_proc member.
5977 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
5978 (cwdr_handler): Removed.
5980 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
5982 * socket.h (SCM_P): update bind prototype.
5983 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
5984 include "feature.h".
5985 (scm_socket): return a port, not a file descriptor object.
5986 include "fports.h" and <unistd.h>
5987 (scm_bind): take a port, not a file descriptor object.
5988 take an extra argument for address args.
5990 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
5991 INADDR_NONE, INADDR_LOOPBACK.
5993 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
5995 * init.c: include net_db.h and not fdsocket.h.
5996 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
5998 * Makefile.am: corresponding changes.
5999 * socket.h: renamed from fdsocket.h, fix names.
6000 * net_db.h: renamed from socket.h, fix names.
6001 * socket.c: renamed from fdsocket.c.
6002 remove _sys from procedure names.
6003 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
6004 add "socket" to features list.
6005 * net_db.c: renamed from socket.c.
6006 remove _sys from procedure names.
6007 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
6008 add "net-db" to features list.
6009 include "net_db.h". don't include <sys/socket.h> or
6012 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6014 * tags.h (scm_tags): Removed comma at end of last enumerator.
6016 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
6018 Don't use GCC extensions to allocate space for debugging frames.
6019 (Here he goes again! Why do we put up with this?!)
6020 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
6021 an scm_debug_info structure, not an in-line array of them. Add
6022 'info' member, to say how many vect elements we've used, for eval
6024 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
6025 a new variable debug_info_end to mark the end of vect, instead of
6026 the address of the 'info' pointer itself.
6027 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
6028 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
6029 (SCM_APPLY): Explicitly allocate space for debug.vect.
6030 * debug.c (scm_m_start_stack): Same, for vframe.vect.
6031 * stacks.c: Adjusted for new debug frame structure.
6032 (RELOC_INFO, RELOC_FRAME): New macros.
6033 (stack_depth, read_frames): Use them, and new scm_debug_frame
6034 element 'info', instead of magically knowing that eval frames have
6035 an info pointer sitting after vect.
6036 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
6038 (scm_init_stacks): Formatting tweaks.
6040 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
6042 Give GCC more control flow information, so it can be sure that
6043 variables aren't used uninitialized.
6044 * error.h (scm_error, scm_syserror, scm_syserror_msg,
6045 scm_sysmissing, scm_num_overflow, scm_out_of_range,
6046 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
6047 scm_misc_error): Tell GCC that these functions never return.
6048 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
6049 out the field type, call abort if SCM_ASSERT returns, to placate
6051 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
6052 scm_wta ever returns. We can't handle this case anyway, and this
6053 gives the optimizer more information.
6054 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
6055 scm_wta ever returns.
6057 In some cases, the code is fine, but GCC isn't smart enough to
6058 figure that out; this usually happens when one variable is only
6059 initialized and used when a particular condition holds true, and
6060 we know that condition will never change within a given invocation
6061 of the function. In this case, we simply initialize the variables
6062 to placate the compiler, hopefully to a value which will cause a
6063 crash if it is ever actually used.
6064 * print.c (scm_iprin1): Initialize mw_pos.
6065 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
6066 * throw.c (scm_ithrow): Initialize dynpair.
6067 * unif.c (scm_uniform_vector_ref): Initialize cra.
6068 * struct.c (init_struct): Initialize prot.
6069 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
6071 * strports.c (scm_eval_0str): Don't return uninitialized garbage
6072 if EXPR contains no expressions.
6074 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6076 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
6077 cause an infinite loop (???). So much for the algebraic
6078 equivalency of variable-sized arrays and alloca...
6080 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
6082 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
6083 a SCM boolean, not a C boolean.
6085 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
6087 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
6088 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
6089 rules for raising scm_mtrigger. Previously, unfortunate but not
6090 unlikely circumstances could result in almost constant invokation
6091 of the gc. Now, this situations should be less likely, but they
6092 are not prevented completely.
6094 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
6096 * numbers.c (scm_fuck): Procedure removed; looks like old test
6098 * numbers.h: Prototype removed.
6100 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
6102 * debug.h (scm_debug_frame): Change `vect' member from an in-line
6103 array to a pointer, to match my Nov 21 change in eval.c.
6105 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6107 * libguile.h: Added #include "libguile/backtrace.h", #include
6108 "libguile/stacks.h".
6110 * strings.c (scm_string scm_make_string scm_string_ref
6111 scm_string_set_x scm_string_equal_p scm_string_append):
6112 Bugfix according to scm patch from Aubrey Jaffer:
6113 Corrected long-standing
6114 (not (eqv? (integer->char 128)
6115 (string-ref (make-string 1 (integer->char 128)) 0)))
6116 bug found by John Kozak <jk@noontide.demon.co.uk>.
6118 * strports.c, strports.h: Make scm_eval_0str return the value of
6119 the last expression evaluated (previously, it returned void).
6121 * strports.c, strports.h: New function: scm_read_0str. Does what
6124 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6126 * simpos.c (scm_getenv): return #f if string can't be found in the
6127 environment instead of throwing an exception, for compatibility
6128 with numerous other systems.
6130 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6132 * Makefile.am (.c.x): Use guile-snarf.
6133 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6135 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6137 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6139 * backtrace.c (scm_display_error_message): Made non-static, and
6140 renamed from display_error_message.
6141 * backtrace.h (scm_display_error_message): Added extern decl.
6142 * throw.c (uncaught_throw): Use it to display the error message.
6144 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6146 * inet_aton.c: Use #if 0, not #ifdef 0.
6148 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6150 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6151 to convert the returned value.
6152 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6153 the offset argument.
6155 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6157 Add new interface to catch/throw, usable from C as well as
6159 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6160 (scm_internal_catch): New function, replaces...
6161 (scm_catch_apply): Deleted.
6162 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6163 mechanism which is a bit more code, but can be used nicely from C
6164 and implement the Scheme semantics as well.
6165 (scm_internal_catch): This is the replacement; it's named after
6166 the analogous function in Emacs.
6167 (scm_catch): Reimplemented in terms of the above.
6168 (struct catch_body_data, catch_body, catch_handler): New
6169 functions, used by scm_catch.
6170 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6171 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6172 support for new cwdr.
6174 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6177 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6179 * acconfig.h: Added DYNAMIC_LINKING symbol.
6180 * configure.in: Add option and checks for dynamic linking.
6181 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6182 dynl.h: New files for dynamic linking support.
6183 * Makefile.am (libguile_a_SOURCES):
6185 (modinclude_HEADERS): Added "dynl.h".
6186 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
6188 * init.c (scm_boot_guile_1): Call
6189 scm_init_dynamic_linking to initialize dynamic linking support.
6191 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
6193 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
6194 (as we Schemers say). It needs to be global, so that I can tweak
6195 it for the proper operation of unexec.
6196 (scm_boot_guile_1_live): New variable, see above.
6198 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
6200 * guile-snarf.sh: Removed.
6201 * PLUGIN/guile.libs: Added dependency for -lm.
6202 * acinclude.m4: Renamed from aclocal.m4.
6203 * PLUGIN/greet: Removed.
6204 * Makefile.am, aclocal.m4: New files.
6205 * configure.in: Updated for Automake.
6207 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
6209 * eval.c (scm_definedp): Use top_level_lookup_closure_var
6210 and not top_level_lookup_thunk_var.
6212 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
6214 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
6216 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
6218 * eval.c (scm_definedp): Incompatibly changed to be a builtin
6219 Scheme function, instead of syntax. Single argument is now a
6222 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6224 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
6225 scm_ra_divide): Properly terminate statements passed as arguments
6226 to IVDEP macros. (Thanks to Bernard Urban.)
6228 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
6229 with non-constant sizes. (Thanks to Bernard Urban.)
6231 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6233 It's an "eval closure", not an "eval thunk." A thunk is a
6234 function of no arguments.
6235 * root.h (struct scm_root_state): Renamed
6236 top_level_lookup_closure_var from top_level_lookup_thunk_var.
6237 (scm_top_level_lookup_closure_var): Renamed from
6238 scm_top_level_lookup_thunk_var.
6239 * root.c (mark_root): Uses changed.
6240 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
6241 * init.c (scm_start_stack): Uses changed.
6242 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
6243 Change scheme-visible name to *top-level-lookup-closure* from
6244 *top-level-lookup-thunk*.
6246 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
6248 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
6249 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
6251 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
6253 * gc.c (struct scm_heap_seg_data): Doc fixes.
6255 * gc.c (scm_gc_sweep): Empty all segments' freelists before
6256 sweeping. Then, prepend each segment's free cells to its
6257 freelist, rather than wiping out the old value. (Thanks to Marius
6260 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6261 scm_check_freelist, scm_debug_newcell): New functions and
6262 variables, for debugging freelist problems.
6263 * pairs.h (SCM_NEWCELL): New debugging version added.
6264 * gc.h (scm_debug_newcell): Added extern declaration, used by
6265 debugging version of SCM_NEWCELL.
6267 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6269 On some systems <libc.h> conflicts with <unistd.h>, and should not
6270 be #included at all.
6271 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6272 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6273 * configure.in: Call it.
6274 * posix.c, filesys.c: Use its results to decide whether or not to
6276 * configure, scmconfig.h.in: Rebuilt with autoconf and
6279 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6281 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6282 pointer to the stdio stream before calling scm_setbuf0, so the
6283 latter will be able to retrieve it. I'm surprised this didn't
6284 segfault earlier. (Thanks to Christopher Lee.)
6286 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6288 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6291 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6293 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6294 number of stack narrowing specifier pairs. The first specifier in
6295 a pair controls inner border, the second the outer border. A
6296 number means cut that number of frames, a procedure object means
6297 cut until that object is found in operator position in a frame.
6299 * root.c (cwdr): Bugfix.
6301 * read.c: Recording of positions disabled by default.
6303 * procs.c (scm_closure_p): New function.
6305 * posix.c (scm_tmpnam): New function.
6307 * load.c: Added #include "throw.h".
6308 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6311 * load.c, load.h (scm_read_and_eval_x): New function.
6313 * eval.c: Renamed debug option "deval" to "debug".
6315 (scm_eval_x): `eval!' is no longer accessible from the scheme
6316 level. Motivation: We can't allow operations which introduce
6317 glocs into the scheme level. Guile's type system can't handle
6318 these as data. Use `eval' or `read-and-eval!' as replacement.
6320 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6321 SCM_CONSP since this is a macro!; Set vframe.prev to
6322 scm_last_debug_frame instead of 0. In this way we can look
6323 "above" the virtual start stack frame if we wish.
6324 (scm_debug_hang): New function: Useful for debugging Guile in
6325 certain tricky situations. Will probably be removed later...
6327 * debug.h: Changed semantics of debug option "backtrace". This
6328 option now only indicates whether we want automatic backtrace at
6331 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6333 * ports.c: #include "filesys.h"
6334 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
6336 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
6337 Motivation: This is system specific code which is related to file
6338 I/O. It also may use select. Added code by Gary Houston to
6339 detect presence of character in stdio buffers.
6341 * libguile.h: #include "libguile/libpath.h"
6343 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
6344 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
6345 SCM_SITE_DIR; Install libpath.h among the other include files.
6347 * load.c, load.h (scm_sys_package_data_dir): New function.
6349 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6351 * stacks.h: Bugfix: Don't use tail-array length field as stack
6352 length field! This screwed GC.
6354 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6356 * _scm.h: Added #ifndef around definition of macros min and max.
6358 * __scm.h: Added hooks for threads to plugin to in ints protection
6359 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
6360 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
6361 the main code in these macros duplicated and spread over multiple
6362 files. Renamed SCM_THREADS_SWITCHING_CODE ->
6363 SCM_THREAD_SWITCHING_CODE.
6365 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
6367 * snarf.h: New file.
6368 * guile-snarf.sh: New file.
6369 * Makefile.in (inner_h_files): Added snarf.h
6370 (ancillary, install, uninstall, distclean): Added actions for
6372 (.c.x): Use guile-snarf.
6373 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
6374 (gen_c_files): Note that these depend on guile-snarf.
6375 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
6376 now in "snarf.h". Added #include "snarf.h" to get them.
6377 * libguile.h: Added #include "snarf.h".
6378 (Patches applied and tweaked by Jim Blandy.)
6380 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6382 * socket.c: Use K&R style declaration for 'close'; the GNU coding
6383 standards suggest against providing prototypes for system
6384 functions. Thanks to Greg Troxel.
6386 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6388 * strports.c (scm_eval_0str): New function.
6389 #include "read.h", to get prototype for scm_read.
6390 * Makefile.in (strports.o): Update dependencies.
6391 * strports.h: New prototype.
6393 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
6394 scheme name from "int?" to "integer?". It seems to do the job.
6395 * numbers.h: Rename prototype too.
6396 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
6399 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
6400 scm_num_eq_p): Rename these according to R4RS conventions: call
6401 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
6402 to making libguile R4RS compliant without ice-9...
6404 * load.c (scm_sys_search_load_path): Search for files under all
6405 extensions listed in the %load-extensions variable. If FILENAME
6406 is absolute, return it unchanged, without searching the load path.
6407 (scm_loc_load_extensions): New variable, pointing to
6408 %load-extensions' value cell.
6409 (scm_init_load): Initialize it, and the value it points to.
6410 (scm_primitive_load_path): Improve error reporting.
6412 * load.c (scm_loc_load_hook): New variable, pointing to value cell
6413 of new Scheme variable %load-hook.
6414 (scm_primitive_load): Apply %load-hook to filename.
6416 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
6418 * configure.in: add tests for figuring out whether buffered data
6419 is available in a FILE structure, which is needed by char-ready.
6421 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
6424 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
6425 exceptions using misc_error instead of syserror. It seems a bit
6426 odd to throw an exception if a string can't be found in the
6427 environment, but it's consistent with open-file, stat etc.
6428 (simpos.h): remove sys_ from getenv.
6430 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
6431 occurs, throw an error instead of returning errno. Return value
6433 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
6435 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
6437 * filesys.c (scm_stat2scm): derive file type and permissions from
6438 the stat mode and append them to the returned vector.
6439 There isn't much overhead in doing this and it avoids the need to
6440 work with S_IRUSR et al. in Scheme.
6441 Define symbols scm_sym_regular etc.
6442 (scm_init_filesys): don't intern S_IRUSR etc.
6444 * load.c: change s_try_load and s_try_load_path to s_primitive_load
6445 and s_primitive_load_path.
6447 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
6449 * error.h: don't declare error symbols. prototype for scm_misc_error.
6451 * stackchk.c (scm_stack_overflow_key): defined here instead of in
6454 * error.c: use SCM_SYMBOL to set up error keys.
6455 scm_misc_error: new procedure.
6457 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
6459 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
6460 between `#!' and `!#' is ignored.
6461 (skip_scsh_block_comment): New function.
6463 * feature.c (scm_set_program_arguments): New argument, FIRST.
6464 * feature.h: Update prototype.
6465 * init.c (scm_boot_guile_1): Pass new argument to
6466 scm_set_program_arguments.
6468 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6470 * init.c (scm_start_stack): Don't initialize scm_progargs here.
6471 (scm_boot_guile): Call scm_set_program_arguments here, later than
6472 the old initialization.
6474 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
6475 initialization procedure.
6476 - Delete in, out, err arguments; there are other perfectly good
6477 ways to override these when desired.
6478 - Delete result argument; this function shouldn't ever return.
6479 - Rename init_func argument to main_func, for less confusion.
6480 - Delete boot_cmd argument; main_func is more general.
6481 -Add 'closure' argument, to help people pass data to main_func
6482 without resorting to global variables.
6483 - Abort if reentered; don't bother returning an error code.
6484 - Call scm_init_standard_ports to set up the default/current
6485 standard ports; no need to pass them to scm_start_stack.
6486 - Remove code to evaluate the boot_cmd, and start the repl; let
6487 the user do something like that in main_func if they want.
6488 - Remove code to package up a return value; main_func can do any
6490 - Call exit (0), instead of returning.
6491 (scm_start_stack): Don't initialize the I/O ports here; that's
6492 weird. Delete in, out, err arguments. Move guts to
6493 scm_init_standard_ports, scm_stdio_to_port.
6494 (scm_init_standard_ports): New function, to set up current and
6495 default standard ports.
6496 (scm_start_stack, scm_restart_stack): Make these static.
6497 * init.h (scm_boot_guile): Adjust declaration.
6498 (scm_start_stack, scm_restart_stack): Remove externally
6499 visible declarations for these.
6500 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
6502 * fports.c (scm_stdio_to_port): New function. Its guts used to be
6503 written out several times in scm_start_stack.
6504 * fports.h: New declaration for the above.
6506 * feature.c (scm_set_program_arguments): New function.
6507 * feature.h: New declaration for the above.
6509 * ports.c: Formatting tweak.
6511 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
6513 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
6514 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
6515 for obtaining the address of a car or cdr field. Motivation:
6516 &SCM_CXR make assumptions about the internal structure of the
6519 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
6520 Motivation: see SCM_CXRLOC.
6522 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
6523 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
6524 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
6525 Motivation: Safer use. Some other macros are defined in terms of
6526 these operations. If these are defined using the SCM_SETCXR
6527 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
6528 to inefficiency and an <e1> with side-effects could potentially
6529 break. Also, these particular operations are heavily utilized in
6530 the garbage collector. In unoptimized code there will be a
6533 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
6534 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
6535 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
6536 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
6537 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
6538 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
6539 vports.c: Cleaned up use of pairs: Don't make any special
6540 assumptions about the internal structure of selectors and
6541 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
6542 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
6543 (Among other things, this change makes it easier to build Guile
6544 with certain compilers which have problems with casted lvalues.)
6546 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6548 * stacks.c: Improve selection of relevant stack frames when making
6549 a stack object. Introduce one level of indirection in the stack
6550 object to make it possible to "narrow" to a certain region of the
6551 stack. This facilitates making use of more clever algorithms (not
6552 implemented) for selecting relevant frames and gives a cleaner
6553 design since selection of frames can be done independently of
6554 extraction of frames from the real stack.
6555 (scm_stack_id): Also take #t as argument which means look at
6558 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
6559 Turn n_tail into an integer directly representing current number
6560 of frames in stack. Add field tail.
6562 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
6564 * debug.c (scm_make_memoized): Made it available at scheme level.
6565 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
6566 SCM_NIMP before applying heavier predicates in argument checking.
6567 (scm_local_eval): Also take memoized object as argument.
6569 * backtrace.c (scm_display_error): Just a safety measure: Stacks
6570 aren't created with zero length, but should such a strange
6571 creature suddenly turn up...
6573 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
6575 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
6576 `del', for the sake of C++ compilers. (Patch applied by JimB.)
6578 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
6580 * variable.c (scm_make_variable): Make the name hint optional, as
6582 (anonymous_variable_sym): Renamed from variable_sym. All uses
6585 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
6586 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
6587 of scm_primitive_load_path was also changed to
6588 "primitive-load-path", from "%try-load-path". Callers changed.
6589 We'd like to respect the convention that a function named
6590 "try-mumble" should behave just like the function called "mumble",
6591 but return #f instead of signalling some error.
6592 * load.h: Rename prototypes.
6594 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6596 * print.c (make_print_state, grow_print_state), print.h: Modified
6597 the print state representation: Don't use a tail array for
6598 recording of circular references. Resizing of the print state
6599 structure invalidates the print state pointer. To avoid passing
6600 around an indirect print state reference to all printing
6601 functions, we instead let the print state reference a resizable
6604 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
6606 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
6607 Don't crash when passed an improper list terminated by a
6608 non-immediate value.
6610 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
6612 Allocate data for structures on an eight-byte boundary, as
6613 required by the tagging system.
6614 * struct.c (alloc_struct): New function.
6615 (scm_make_struct, scm_make_vtable_vtable): Call it.
6616 * struct.h (scm_struct_n_extra_words): Bump to 3.
6617 (scm_struct_i_ptr): New "field".
6618 * gc.c (scm_gc_sweep): When we need to free the data, use the
6619 information stored by alloc_struct to find the beginning of the
6620 block allocated to the structure, so we can free it.
6622 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6624 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
6627 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
6628 (scm_debug_info): New member: id.
6630 * stacks.c: Stacks are now represented as structs; Stacks have an
6631 id given to them by `start-stack'.
6632 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
6634 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
6635 Changed stack representation.
6637 * debug.c (scm_procedure_name): Try procedure property `name' for
6638 compiled closures aswell.
6640 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
6642 * eval.c: scm_i_name moved to gsubr.c
6643 (scm_m_define): Record names of all kinds of procedure
6644 objects. (Earlier, only closures were recorded.)
6646 * procprop.h: Added declaration of scm_i_name.
6648 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
6649 (scm_make_gsubr): Record names of compiled closures.
6651 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6653 * debug.c, debug.h: Removed obsolete code.
6655 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
6656 stacks.c: Renamed regs --> scm_contregs.
6658 * print.c (scm_free_print_state): Cleanup print state before
6659 returning it to pool. It is better to do it here than in
6660 scm_prin1 since scm_prin1 is called often.
6662 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
6663 s_set_source_property_x): Check that first argument is a pair or a
6666 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
6667 scm_i_line, scm_i_column and scm_i_breakpoint global.
6669 * init.c: Added #include "backtrace.h" and #include "stacks.h".
6670 (scm_boot_guile_1): Added calls to scm_init_backtrace and
6673 * debug.h: Added debug object smob declaration and macro
6676 * configure.in: Build with backtrace.o and stacks.o if debug
6679 * Makefile.in: Added entries for new files: backtrace.c,
6680 backtrace.h, stacks.c and stacks.h.
6682 * symbols.c (scm_sym2ovcell): Fixed documentation.
6684 * _scm.h (min, max): Added.
6686 * async.c: Moved `min' macro to _scm.h.
6688 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
6689 SCM_BACKTRACE_INDENT.
6691 * eval.c: Added new debug options `maxdepth' and `indent'.
6693 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
6695 * print.h: Added selector SCM_PRINT_STATE.
6697 * print.c: New functions: scm_make_print_state,
6698 scm_free_print_state.
6700 * print.h: Added declarations for scm_make_print_state,
6701 scm_free_print_state.
6703 * debug.c (scm_m_start_stack): New acro.
6705 * debug.h: Small cleanup.
6707 * init.c (scm_boot_guile_1): Moved scm_init_debug below
6710 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

6735 More prototype-related changes from Marius Vollmer:
6736 * gdb_interface.h: Wrapped header file in #ifdef/#endif
6737 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
6738 * ports.h (ptobfuns): Added prototypes. This means some casting in
6740 * fports.c: Added casts for initializations, since the functions
6741 are defined to take FILE * as their stream argument, not SCM.
6742 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
6743 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
6744 to `char *str_data' to conform to prototype.
6746 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
6748 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
6750 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
6752 * stime.c, stime.h: use SCM_P method.
6754 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
6756 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
6757 be given at least two arguments. Insist that lst's last element
6758 be a list, but don't make any requirements of its predecessors.
6760 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
6762 * eval.c (scm_nconc2last): Revert last change; there seems to be
6763 other stuff going on here.
6765 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
6767 * eval.c (scm_nconc2last): Make sure that each element of lst
6768 (which is a list of argument lists, except for the tail) is a
6769 proper list, i.e., finite and terminated by '().
6771 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6773 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
6776 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
6777 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
6780 * vectors.c (scm_make_vector): Fill vectors with the undefined
6781 value, to help make Guile Scheme code more portable to other
6784 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
6785 * symbols.h, tags.h: Doc fixes.
6787 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>

6791 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
6793 * numbers.c (scm_divbigint): When the remainder is zero, we don't
6794 want to subtract it from the modulus; we just want to leave it
6797 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
6799 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to

6804 * throw.c (scm_catch_apply): Finished implementation of
6807 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
6809 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
6811 (scm_init_filesys): set "i/o-extensions" feature.
6814 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
6816 * Makefile.in (root.o): Correct dependencies.
6818 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
6820 * Makefile.in: Added dependency entry for root.o.
6822 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
6823 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
6825 * init.c (scm_start_stack): Set initial root continuation number
6828 * procs.c: New function: scm_thunk_p.
6830 * procs.h: Added declarations of scm_thunk_p.
6832 * root.c: Renamed `call-with-new-root' -->
6833 `call-with-dynamic-root'.
6834 (cwdr): Removed allocation of new root state. This should be done
6835 separately by use of scm_make_root.
6836 (scm_apply_with_dynamic_root): New function: Does what it
6837 sounds like. Needed when spawning threads.
6839 * root.h: Added member last_debug_frame to root state.
6840 Added #include "libguile/debug.h"
6842 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
6843 arguments. The motivation is that code in root.c needs catch
6844 functionality, and we want to avoid code duplication.
6845 New functions: scm_catch, scm_lazy_catch. These are wrappers for
6846 scm_catch_apply. scm_lazy_catch is intended to introduce catch
6847 handlers that run without popping the stack into the dynwind
6850 * throw.h: Added prototypes for scm_catch_apply and
6853 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6855 * root.h (scm_root, scm_set_root): Decouple thread support details
6856 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
6857 SCM_SET_THREAD_LOCAL_DATA.
6859 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
6860 and tortoise scanning loop.
6862 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
6864 * Makefile.in: Rebuild dependencies.
6866 * libguile.h: #include "libguile/print.h" before "smob.h", since
6867 the latter uses the print_state structure.
6869 * throw.c (scm_ithrow): Use the correct variable when checking to
6870 see if a given element of scm_dynwinds is a valid catch.
6872 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
6873 structure, abort; don't just silently ignore the garbage.
6875 * _scm.h: #include "print.h" here, since it seems to be used just
6877 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
6878 strports.c, unif.h: Don't #include "print.h".
6880 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6882 * feature.h (scm_loc_features): Removed external declaration.
6883 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
6885 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6887 * feature.c (scm_init_feature): Added threads feature (needs to be
6888 initialized here, since features doesn't exist when
6889 scm_init_threads is called).
6891 * libguile.h: Added #include "libguile/../threads/threads.h".
6892 (This is a kludge to get thread support working. This should be
6895 * configure.in, acconfig.h: Added flags for thread support.
6897 * scmsigs.c: Define `signal' to be `pthread_signal' if using
6900 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
6901 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
6904 * _scm.h: Added conditional #include "threads.h"
6906 * __scm.h (SCM_ASYNC_TICK): Added call to macro
6907 SCM_THREADS_SWITCHING_CODE.
6909 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
6910 allocate the basic dynamic root object.
6911 (scm_boot_guile): Added call to scm_init_root.
6913 * root.c, root.h: Added root smob.
6914 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
6915 functions: Implements dynamic roots mostly according to spec in
6916 SCM manual. Main difference is that the second argument is a
6917 throw handler rather than an error "thunk".
6919 * root.h: Added declaration of scm_init_root.
6921 * root.c: Added #include "genio.h", #include "smob.h", #include
6922 "pairs.h", #include "throw.h", #include "dynwind.h", #include
6924 (scm_init_root): Added #include "root.x".
6926 * throw.c: Added #include "stackchk.h"
6927 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
6928 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
6929 can be used in scm_call_with_new_root; Added reenabling of stack
6930 checking when catching a throw.
6932 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
6934 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
6936 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
6937 element is not found, as per R4RS.
6939 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
6941 * list.c: Doc fixes throughout.
6943 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6945 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
6946 declare the char * to be const. Avoids a warning in rgx.c.
6948 * ports.h: spelling fix.
6950 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
6953 * load.c (scm_sys_try_load_path): throw an error if file not found
6954 (like it says it in NEWS).
6956 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
6958 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
6959 PROPS slot to '(), not #f; it's an empty alist.
6961 * throw.h, throw.c: Use SCM_P instead of #if hair.
6963 Remove special support for uncaught throws; see throw.c for
6965 * throw.c (uncaught_throw): New function.
6966 (scm_ithrow): Call uncaught_throw if we don't find a throw
6967 target; don't mess with scm_bad_throw_vcell.
6968 (scm_bad_throw_vcell): Variable deleted.
6969 (scm_init_throw): Don't initialize it.
6971 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
6974 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6976 * numbers.c (scm_istr2int): If the number is short (as most
6977 numbers are), just call scm_small_istr2int to deal with it.
6978 (scm_small_istr2int): New function, created by un-#ifdefing the
6979 non-bignum version of scm_istr2int and renaming it.
6981 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
6983 * load.c (scm_sys_try_load): don't check whether value returned
6984 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
6985 Change the Scheme name from %try-load to primitive-load.
6987 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
6988 Can avoid passing a message, allowing it to be derived in the
6989 error handler (e.g., if we want to throw to the key both from
6992 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
6994 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
6995 references now have a new appearance which is more compact and
6996 also gives a clue about what the target of the reference is.
6997 By setting parameters in the print state, more fancy printing can
6998 be achieved. This is used by the (not yet commited) backtrace
7001 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
7003 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
7006 * print.c: Added #include "struct.h". Removed function
7009 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
7010 scm_iprin1. Removed prototype for scm_prlist.
7012 * arbiters.c (prinarb),
7013 async.c (print_async),
7014 debug.c (prindebugobj, prinmemoized),
7015 eval.c (prinprom, prinmacro),
7016 filesys.c (scm_fd_print, scm_dir_print),
7018 mallocs.c (prinmalloc),
7019 numbers.c, numbers.h (scm_floprint, scm_bigprint),
7020 smob.h (scm_smobfuns),
7021 srcprop.c (prinsrcprops),
7023 unif.c, unif.h (scm_raprin1, rapr1),
7024 variable.c (prin_var): Changed argument `int writing' to
7025 `scm_print_state *pstate'.
7027 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
7028 that it will be called before scm_init_print.
7030 * print.c (scm_prin1): Print states are now allocated when calling
7031 scm_prin1 and then passed around to all printing functions as an
7032 argument. A cache `print_state_pool' enables reuse of print
7034 (scm_make_print_state): New function.
7035 (scm_iprin1): Adaption to print states.
7036 (scm_iprlist): An initial "hare and tortoise" scan brings down
7037 time complexity to O (depth * N). (Better time complexity will be
7038 achieved when the printing code is completely rewritten.)
7040 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7042 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
7043 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
7044 it gets done whether or not the cache variable has a value.
7046 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7048 Distinguish #f and ().
7049 * __scm.h: #undef SICP.
7050 * pairs.h (SCM_EOL): Delete this definition, equating it with
7052 * tags.h (SCM_EOL): Give it a new definition here; I think I found
7053 the value it used to have. Doc fixes, too.
7055 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
7057 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
7058 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
7059 Lord's implementation of structs, allowing for tail arrays as
7060 described in the manual. Also fixed some bugs. (Both the interface
7061 and the implementation should be improved.)
7063 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
7065 * print.c, print.h: Closures now print like #<procedure foo (x)>.
7066 People who whish to see the source can do `(print-enable 'source)'.
7067 Removed #ifdef DEBUG_EXTENSIONS.
7069 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7071 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
7072 integer (assuming for now accepting an integer is a good thing).
7074 * error.c, fports.c: replace use of %S in lgh_error args with %s.
7075 %S will be used instead for write'ing arguments.
7077 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
7078 asserts. fix a few other asserts.
7079 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
7080 scm_uniform_vector_ref, scm_array_set_x,
7081 scm_dimensions_to_unform_array): change args in
7082 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
7083 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
7084 scm_substring_fill_x): likewise.
7085 gsubr.c (scm_gsubr_apply): likewise.
7086 eval.c (SCM_APPLY): likewise.
7088 * eval.c (4 places): replace scm_everr with lgh_error or
7091 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
7092 scm_memory_error): new procedures.
7093 scm_everr: deleted. can use scm_wta, dropping first two args.
7094 scm_error: convert NULL subr to SCM_BOOL_F.
7096 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
7099 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
7102 * error.c, error.h: new error keys: scm_arg_type_key,
7103 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
7105 scm_wta: reimplement using lgh_error instead of scm_everr.
7107 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
7109 * gdbint.c: scm_lread now has one more argument.
7111 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
7112 scm_port_\1; Added mutator scm_set_port_filename_x (used when
7113 loading source from non-file ports, which, e. g., happens when
7114 using the Emacs interface).
7116 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
7119 * read.c: Added code for recording of positions of source code
7120 expressions; New functions: recsexpr, scm_lreadrecparen;
7121 _scm_make_srcprops --> scm_make_srcprops
7122 (scm_flush_ws): Removed updating of positions counters. This work
7123 is already done by scm_gen_getc
7125 * read.h: Added prototype for scm_lreadrecparen
7127 * print.c: Added #include "alist.h"
7129 * eval.c: Added #include "hash.h"
7131 * eq.c: Added #include "ramap.h"

7137 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7138 --> scm_make_srcprops
7140 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7141 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7142 function calls in the definition of the whash access macros.
7144 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7146 * init.c (scm_boot_guile): Add level of indirection to
7147 scm_boot_guile_1() to ensure that stack base pointer is properly
7148 initialized. There was no guarantee that variable i was the
7149 highest/lowest variable on stack (i.e. the call frame of
7150 scm_boot_guile was not completely protected from gc).
7152 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7154 * ports.h (scm_port_table): put back file_name, it will be used to
7155 support debugging. Undo related changes in fports.c, ioext.c,
7158 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7160 * ports.h (scm_port_table): remove file_name member for now, it seems
7162 * fports.c (scm_open_file): don't set file_name in PTAB.
7163 (prinfport): don't use file_name in PTAB.
7164 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7165 * ports.c (scm_add_to_port_table): don't intialize file_name.
7166 (scm_port_file_name): remove for now.
7167 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7169 * fports.h (scm_mkfile): prototype deleted.
7170 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7172 * debug.c, unif.c: use scm_out_of_range instead of
7173 wta for range errors (ASSERT still needs work).
7175 * error.c, error.h (scm_out_of_range): new procedure.
7177 * error.c, error.h (scm_out_of_range_key): new key.
7179 * posix.c (scm_sync): #else was missing.
7181 * error.c, error.h: append _key to names scm_num_overflow and
7184 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
7185 of consing an empty list.
7186 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
7187 of macros, saves code and string space.
7188 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
7189 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
7190 lower case. Rename scm_syserror_m to scm_syserror_msg.
7191 error.h: prototypes for new procedures.
7193 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
7195 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
7197 * error.c, error.h: setup scm_num_overflow key.
7199 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
7200 Remove definition of SCM_OVSCM_FLOW.
7202 * fports.c (scm_open_file): use SCM_SYSERROR_M.
7204 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
7205 explicit message and args.
7207 * error.c, error.h, __scm.h: change system_error_sym to
7210 * error.c (system_error_sym): remove leading %% from the Scheme name
7213 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
7215 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7217 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
7218 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
7219 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
7220 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
7221 renamed. (These were introduced by unsupervised name
7224 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7226 * print.c: Added code for detection of circular references during
7227 printing. (init_ref_stack, grow_ref_stack): New functions. Added
7228 a hook for printing of closures (accessible via print options).
7229 This leads to a split of calls to scm_iprin1 into two classes:
7230 elementary print operations (e. g. the code which prints a smob)
7231 still use scm_iprin1 while top level calls (like scm_display) use
7232 scm_prin1. scm_prin1 begins by clearing the data structure used
7233 to record reference information.
7235 * print.h: Added declarations of scm_prin1 and scm_prlist.
7237 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
7239 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
7241 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
7243 * error.c (err_head): scm_iprin1 --> scm_prin1
7245 * debug.c: Adjusted header comment.
7249 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>

7253 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7255 * gdbint.c (gdb_read): Now possible to run during GC.
7256 (unmark_port, remark_port): New functions.
7258 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7260 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7261 of allocating a new string object. Also, increase size by
7262 the factor 2 instead of 1.5.
7264 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7266 * __scm.h (SCM_P): Corrected to run under traditional C.
7268 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7271 * async.c: Calls to scm_sysintern corrected.
7273 * async.h (scm_async_clock): Redundant declaration removed.
7275 * continuations.c (scm_dynthrow): Redundant declaration removed.

7278 Definition typos corrected.
7280 * debug.h: Missing declarations of functions in debug.c added
7283 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7284 Missing declarations to functions in eval.c added.
7286 * filesys.c: Possibly uninitialized variable rv.
7288 * gc.h (scm_object_addr, scm_unhash_name): Missing
7289 declarations of functions defined in gc.c added.
7291 * genio.c: Possible typos str_data -> wstr_data. ???
7293 * genio.c: Possibly unintended shadowing of local variable
7294 `int c' (gotos out of scope of inner `c'). ???
7296 * init.c: Uninitialized `SCM last' may be used.
7298 * ioext.h: (scm_sys_isatty_p): Typo.
7300 * list.h (scm_list_head): Missing prototype for function in
7303 * numbers.c (scm_two_doubles): Changed from extern to static
7304 (is used only within numbers.c).
7306 * numbers.h: Repeated declarations removed.
7308 * ports.h (scm_close_all_ports_except): Declaration for the
7309 function defined in ports.c added.
7311 * posix.h: Missing declarations added.
7313 * procs.h (scm_make_subr_opt): Missing declaration added.
7315 * socket.h (scm_sys_gethost): Missing declaration added.
7317 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7319 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7320 Missing declarations added.
7322 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
7324 * struct.c: Uninitialized variable `SCM answer' may be used.
7326 * unif.c (l2ra): Declaration prototype.
7328 * unif.c (scm_array_equal_p): Dummy definition removed (it is
7329 defined in ramap.c).
7331 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
7332 Redundant declarations removed (they are in ramap.h).
7334 * variable.h (scm_make_udvariable,
7335 scm_make_undefined_variable): Declaration corrected to
7336 correspond variable.c.
7338 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
7339 Missing declarations added.
7341 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
7343 * Makefile.in (distclean): Don't forget to delete fd.h.
7345 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7347 * fd.h.in, tags.h: Trivial cleanups.
7349 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
7350 marksweep.h just declared functions from gc.c.
7351 * gc.h, libguile.h: Don't #include "marksweep.h".
7352 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7353 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
7354 dependencies updated.
7356 * libguile.h: Don't #include "files.h"; it's been deleted.
7358 * files.c (scm_sys_delete_file): Moved to filesys.c.
7359 File is now empty; deleted.
7361 * filesys.c: scm_sys_delete_file is now here. Remove
7362 #if's; they seem to rely on remnants of an old portability
7363 regimen. If the problems come up again, solve them properly,
7364 using autoconf. Specifically: Don't test M_SYSV, and #define
7365 remove to be unlink if it's #defined; don't use remove just
7366 because HAVE_STDC_HEADERS is #defined.
7367 * filesys.h: Add declarations for scm_sys_delete_file.
7368 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7369 files.o, files.h, files.c, and files.x.
7370 * init.c: Don't #include "files.h", and don't call scm_init_files.
7372 Use SCM_P instead of PROTO; the latter intrudes on the user's
7374 * params.h: Deleted; definition of SCM_P moved to...
7375 * __scm.h: ... here, where it replaces PROTO macro.
7376 * libguile.h, smob.h: Don't #include "params.h".
7377 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
7378 smob.h: Fix prototypes accordingly.
7379 * Makefile.in: Update dependencies.
7380 (inner_h_files): Remove params.h.
7382 * gc.c: #include "gc.h"; every module should include its header,
7383 to let the compiler cross-check the declarations against the
7386 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
7387 simpos.h: #include "libguile/__scm.h".
7389 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
7391 * init.c: Don't forget to #include smob.h and init.h.
7392 * Makefile.in: Dependencies updated.
7394 * smob.h: Use PROTO instead of #if __STDC__.
7396 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
7398 * __scm.h: Doc fixes.
7400 * __scm.h, libguile.h: Use "quotes" in the #includes, not
7401 <angles>; this allows `make depends' to work properly.
7403 * libguile.h: #include smob.h and pairs.h before the others; they
7404 define typedefs used by other headers.
7406 C files should #include only the header files they need, not
7407 libguile.h (which #includes all the header files); the pointless
7408 recompilation was wasting my time.
7409 * Makefile.in (all .o dependency lists): Regenerated.
7410 * libguile.h: Don't try to get a definition for size_t here...
7411 * __scm.h: Do it here.
7412 * _scm.h: Since this is the internal libguile header, put things
7413 here that all (or a majority) of the libguile files will want.
7414 Don't #include <libguile.h> here; that generates dependencies on
7415 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
7416 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
7417 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

7513 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
7514 * weaks.c: Get "weaks.h".
7516 * stackchk.h: #include "libguile/debug.h",
7518 * print.h, read.h: #include "options.h", since everyone who uses
7519 either of these files will need that.
7521 * smob.h: #include "ports.h", "genio.h", and "print.h", since
7522 anyone who uses this file will need them to define the smob
7523 printing functions. Also, get markers.h, since people will need
7524 to #define the mark functions.
7526 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
7527 * ports.h: ... to here.
7529 * ports.h (scm_port_table_size): Explicitly give type as 'int';
7530 don't rely on archaic C default type rules.
7532 * fports.h: #include "libguile/ports.h", since you need that in
7533 order to parse this.
7535 * genio.h: #include "libguile/print.h", because you need that to
7536 parse this; don't bother #including "ports.h", since print.h gets
7539 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
7541 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
7542 this; it's now a reference to an element of *scm_root.
7544 * debug.h: Don't #include "options.h"; the compiler won't be able
7545 to find that once the headers are installed; instead, #include
7546 "libguile/options.h".
7547 * gc.h: Same, with marksweep.h.
7548 * mbstrings.h: Same, with symbols.h.
7549 * scmhob.h: Same, with _scm.h.
7550 * smob.h: Same, with params.h.
7552 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
7553 C files; there's no need for this, and it forces recompilations
7556 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
7558 * error.c (scm_error): declare scm_error_callback.
7560 * error.h: prototype for scm_error_callback.
7562 * __scm.h: define lgh_error.
7563 (SCM_SYSERROR): redefine using lgh_error.
7565 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
7567 * error.c (scm_error): new procedure.
7569 * error.h: prototype for scm_error.
7571 * Makefile.in (install): install scmconfig.h from the current
7572 directory, not $(srcdir).
7574 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7576 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7577 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7578 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
7579 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
7580 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,

7583 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
7584 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7585 vports.h, weaks.h: #include "libguile/__scm.h", not
7586 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
7587 dependencies are within libguile properly.
7589 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7591 * Makefile.in (.c.x): Simplify; there's no need to run this rule
7592 when scmconfig.h doesn't exist.
7594 * load.c (scm_sys_try_load): Correct spelling.
7596 * feature.c (scm_loc_features): Make this static.
7598 * Makefile.in (libpath.h): Omit trailing slash from path. We
7599 shouldn't require it of users, so why put it here?
7601 Move code to initialize and search %load-path from ice-9 to C
7602 code, so we can use the load-path to find the ice-9 boot code;
7603 this makes it easier to run Guile without installing it. See
7604 corresponding changes in guile/Makefile.in.
7605 * feature.c: Move stuff concerned with the load path to load.c.
7606 (scm_compiled_library_path): Deleted.
7607 Don't #include libpath.h here.
7608 * feature.h: Don't mention scm_compiled_library_path.
7609 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
7610 <sys/stat.h>, and <unistd.h> (if present).
7611 (R_OK): #define if the system hasn't deigned to.
7612 (scm_loc_load_path): New variable.
7613 (scm_init_load_path, scm_sys_search_load_path,
7614 scm_sys_try_load_path): New functions.
7615 (scm_init_load): Initialize scm_loc_load_path to point to the
7616 value cell of the Scheme %load-path variable.
7617 * load.h: Add declarations for scm_sys_search_load_path,
7618 scm_sys_try_load_path.
7619 * init.c: Call scm_init_load_path.
7620 * Makefile.in (feature.o, load.o): Dependencies updated.
7622 * load.c, load.h: Rewrite using PROTO macro.
7624 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7626 * gc.c (scm_cellp): New function: C predicate to determine if an
7627 SCM value can be regarded as a pointer to a cell on the heap.
7629 * gc.h: Added declaration of scm_cellp.
7631 * gdb_interface.h: New file: The GDB interface header from the GDB
7634 * gdbint.c: New file: GDB interface.
7636 * gdbint.h: New file: GDB interface.
7638 * libguile.h: Added #include <libguile/gdbint.h>.
7640 * init.c (scm_boot_guile): Added scm_init_gdbint.
7642 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
7643 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
7644 found if object files and source are kept separate).
7646 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
7648 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
7650 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
7652 * configure.in: Don't substitute the values of TCL_SRC_DIR and
7653 TK_SRC_DIR; they're not relevant any more.
7655 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
7656 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
7658 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
7660 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
7661 search path, so we can find the <libguile/MUMBLE.h> headers.
7663 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
7665 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
7666 implicit in the .c.o rule.
7667 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
7670 Put the library path in a header file, instead of passing it on
7671 the command line in every compilation.
7672 * Makefile.in (libpath.h): New target.
7673 (feature.o): Depend on libpath.h.
7674 (clean): Delete libpath.h.
7675 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
7676 * feature.c: ... #include "libpath.h" here.
7677 * .cvsignore: Ignore libpath.h.
7679 Don't install the unwashed masses of Guile header files in the
7680 main #include path; put most of them in a subdirectory called
7681 'libguile'. This avoids naming conflicts between Guile header
7682 files and system header files (of which there were a few).
7683 * Makefile.in (pkgincludedir): Deleted.
7684 (innerincludedir): New variable; this and $(includedir) are enough.
7685 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
7686 (installed_h_files): Divide this up. Now this variable lists
7687 those header files which should go into $(includedir) (i.e. appear
7688 directly in the #include path), and ...
7689 (inner_h_files): ... this new variable says which files appear in
7690 a subdirectory, and are referred to as <libguile/mumble.h>.
7691 (h_files): List them both.
7692 (install): Create innerincludedir, not pkgincludedir. Put
7693 the installed_h_files and inner_h_files in their proper places.
7694 (uninstall): Corresponding changes.
7695 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7696 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7697 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
7698 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
7699 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
7700 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
7701 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
7702 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
7703 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7704 vports.h, weaks.h: Find __scm.h in its new location.
7705 * __scm.h: Find scmconfig.h and tags.h in their new locations
7706 (they're both "inner" files).
7708 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
7710 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
7712 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7714 * posix.c: Doc fixes.
7716 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
7718 * socket.c: Don't include a prototype for inet_aton; just use a
7719 K&R style declaration, to avoid warnings but minimize the chance
7720 of conflicts with the system.
7722 On NextStep, <utime.h> doesn't define struct utime, unless we
7723 #define _POSIX_SOURCE before #including it.
7724 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
7725 * acconfig.h: New comment text for above CPP symbol.
7726 * configure.in: Call it.
7727 * posix.c: #define _POSIX_SOURCE if it seems necessary.
7729 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
7731 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
7732 testing for __EMX__.
7734 * posix.c: #include <libc.h>, if it exists.
7736 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
7737 don't even know if the latter exists.
7739 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
7740 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
7741 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
7743 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
7745 (scm_init_posix): Use them when initializing the Scheme constants
7748 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
7750 * Makefile.in (libdir, includedir, bindir): Use the
7751 autoconf-supplied values, instead of deriving them ourselves.
7752 (pkgincludedir, datadir, pkgdatadir): New variables.
7753 (install, uninstall): Put the header files in a special
7754 subdirectory, not in the main search path.
7756 * Makefile.in (ALL_CFLAGS): Provide the proper value for
7757 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
7759 * Makefile.in (IMPLPATH): Deleted; never used.
7761 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
7762 on the Tcl/Tk source any more.
7763 (INCLUDE_CFLAGS): Remove references to the above.
7765 * Makefile.in (version.o): Corrected dependencies.
7767 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
7769 * libguile.h: #include "version.h"
7771 * init.c (scm_boot_guile): Call scm_init_version.
7772 * gscm.c (gscm_run_scm): Call scm_init_version.
7774 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
7775 GUILE_VERSION): AC_DEFINE these.
7776 (acconfig.h): #undef the above symbols.
7778 * Makefile.in (libobjs): Add version.o.
7779 (installed_h_files): Add version.h.
7780 (c_files): Add version.c.
7781 (gen_c_files): Add version.x.
7782 (version.o): New rule.
7783 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
7784 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
7785 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
7786 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,

7792 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
7793 weaks.o): Add version.h to dependency lists.
7794 (markers.o): Remove duplicate rule.
7796 * version.h: New file.
7798 * version.c: New file.
7800 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7802 * symbols.c (scm_strhash): scm_downcase is now a function, not an
7803 array; use it appropriately. Since GCC is quite happy to
7804 subscript functions, it never warned us about this; we should use
7805 -Wpointer-arith in the future. I guess we never tested
7808 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
7810 * socket.c: Doc and copyright fixes.
7812 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7814 * debug.c: Fixed and improved gdb support.
7816 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7818 * socket.c: Added declaration of inet_aton to avoid compiler
7819 warning. (Hope this solution is correct.)
7821 * stime.c: Added declaration of ftime. (This is missing in
7824 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
7826 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
7828 * Makefile.in (c_files): add strerror.c.
7830 * strerror.c: new file from Emacs' sysdep.c.
7831 maybe configure should also check for sys_errlist.
7833 * configure.in (AC_REPLACE_FUNCS): add strerror.
7835 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7837 * debug.c (scm_init_debug): Added initialization for
7838 scm_evaluator_traps.
7840 * debug.h, debug.c: Various name changes.
7841 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
7842 "debug-options-interface". See commentary in options.c.
7844 * options.h, options.c: Options now have documentation strings.
7845 Also added a long explanatory commentary.
7847 * eval.c, print.h, print.c, read.h, read.c: Modifications to
7850 * gscm.c, init.c, root.c, throw.c: Bug fixes:
7851 last_debug_info_frame is now updated in all cases.
7853 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
7856 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7858 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
7859 Added option STACK_CHECKING.
7861 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7863 * Makefile.in: Added {debug,options,srcprop}.{h,c}
7865 * __scm.h: Removed symbols for debugging support.
7867 * acconfig.h: Added symbols for debugging support.
7869 * configure.in: Added user option for debugging support.
7870 --enable-debug will include the debugging code into libguile.a.
7872 * continuations.c (scm_make_cont): Enlarged the #if 0 around
7873 scm_relocate_chunk_to_heap.
7875 * debug.c: New file: low-level debugging support. It also
7876 includes support for debugging with gdb. (The extensions to gdb
7877 are written by Per Bothner at Cygnus.)
7879 * debug.h: New file: low-level debugging support.
7881 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
7882 argument pairs. Extensive modifications to the debugging
7883 evaluator. Added "SECTION:" commentaries to clarify what happens
7884 when, during double compilation. Renamed EVALIMP --> EVALIM.
7885 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
7886 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
7887 the beginning of the file. New procedure: scm_unmemocopy.
7888 Added some global state variables needed by the debugging
7889 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
7890 check_entry, check_apply, check_exit, debug_options and
7891 evaluator_traps. New acro: undefine.
7893 * eval.h: Renamed EVAL --> XEVAL.
7895 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
7896 --> scm_make_weak_key_hash_table.
7898 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
7899 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
7901 * libguile.h: Conditionally include debug.h
7903 * objprop.c (scm_object_properties, scm_set_object_properties_x):
7904 scm_object_properties shouldn't return handle. `handle' now gets
7905 initialized in scm_set_object_properties_x. scm_object_properties
7906 doesn't any longer create an entry in scm_object_whash.
7908 * options.c: New file: handling of run time options.
7910 * options.h: New file: handling of run time options.
7912 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
7914 * print.c: New procedure: scm_print_options
7916 * print.h: Defines for print options.
7918 * read.c: New procedure: scm_read_options
7920 * read.h: Defines for reader options.
7922 * root.h: Added scm_source_whash among scm_sys_protects.
7924 * srcprop.c: New file: source properties.
7926 * srcprop.h: New file: source properties.
7928 * throw.c (jbsmob): Jump buffers are now correctly allocated.
7929 (Bug found by A. Green.)
7931 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
7933 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
7935 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
7937 * libguile.h: #include "objprop.h"; I guess this was forgotten.
7939 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
7940 and should be called by the final client.
7942 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
7944 * gc.h: Use the PROTO macro when declaring functions.
7945 * gc.c: Use the PROTO macro when declaring static functions.
7946 Remove the CPP hair around function definitions.
7948 * gc.c (scm_init_storage): Initialize scm_asyncs.
7950 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
7951 preprocessor symbol; "__scm.h" is where it might get #defined.
7952 * __scm.h: Similar: #include <scmconfig.h> before testing
7955 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
7957 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
7959 * init.c (scm_boot_guile): Add init_func argument; call
7960 (*init_func) instead of calling scm_appinit; it's ucky to
7961 hard-code names for the user's procedures.
7962 * init.h (scm_boot_guile): Adjust declaration.
7964 * __scm.h (PROTO): New macro, for declaring functions with
7967 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
7968 eliminate all the __STDC__ conditionals.
7969 (scm_boot_guile): Add declaration.
7970 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
7971 Remove __STDC__ conditionals around function definitions; the
7972 declarations in init.h will provide the same information, more
7975 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
7976 complain about it in the error message; the error message is
7977 adequate without that note, and there's nothing the user can do
7980 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
7982 * Makefile.in (ancillary): Drop def.sed.
7984 * posix.c (scm_init_posix): Use numeric values, rather than
7985 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
7986 F_OK. The symbols aren't available on some systems, and I'm
7987 pretty sure their values are fixed by common widespread practice.
7988 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
7990 More functions unavailable on some systems.
7991 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
7992 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
7994 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
7995 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
7996 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
7997 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
7998 stub that signals an error as the #else.
8000 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
8002 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
8004 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
8006 * unif.c: include ramap.h.
8008 * read.c (endif): case_insensative_p renamed case_insensitive_p.
8010 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
8012 * ports.c: include sys/ioctl.h.
8014 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
8016 * configure.in: check for sys/ioctl.h.
8018 * ports.c: include <malloc.h> not "malloc.h".
8020 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8022 * fports.c: remove ttyname and tmpnam declarations.
8024 * posix.c: fewer ttyname declarations.
8026 * fports.c: include <string.h> not "string.h".
8028 * init.c, ioext.c: include string.h and unistd.h.
8030 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8032 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
8033 genio.c, simpos.c, vports.c: include string.h.
8035 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
8037 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
8039 (scm_addr_buffer_size): change type from scm_sizet to int.
8040 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
8041 from scm_sizet to int.
8043 * error.c: include unistd.h.
8045 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
8048 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
8050 * __scm.hd, def.sed: deleted.
8052 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
8054 Changes for NeXT, suggested by Robert Brown.
8055 * configure.in: Call AC_TYPE_MODE_T.
8056 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
8057 NeXT. Put header file list in alphabetical order.
8058 * configure, scmconfig.h.in: Regenerated.
8059 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
8061 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
8064 * acconfig.h: New file, providing documentation for the CPP
8065 symbols defined in configure.in
8066 * acconfig-1.5.h: Removed; superceded by the above.
8068 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
8070 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
8072 * fports.c (scm_open_file): don't return #f, throw error.
8074 * ioext.c (fileno): renamed from %fileno.
8075 (soft-fileno): deleted.
8077 * ports.c (scm_port_revealed): don't need to check for -1 from
8079 (scm_set_port_revealed_x): return unspecified, not #f.
8081 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
8083 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
8085 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
8087 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
8089 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8091 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
8092 This is necessary on Ultrix, and doesn't hurt portability.
8094 * Makefile.in (dist-dir): New target, implementing a new dist system.
8095 (installed_h_files): Put in alphabetical order.
8096 Remove duplicate entries for markers.h and unif.h.
8097 (c_files): Remove duplicate entries for markers.c.
8098 (ancillary): Renamed from anillery; all uses changed. Remove
8099 PLUGIN; it's a directory, and needs special treatment in dist-dir.
8100 Remove all the ../doc/* files; doc/Makefile.in handles that.
8102 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
8104 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
8105 every if must have an else, or else the whole command has a
8106 non-zero exit code whenever the if's condition is false.
8108 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
8110 * posix.c: include string.h.
8112 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
8114 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
8117 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
8118 Remove leading % from scheme names.
8119 Do not return error values, call SCM_SYSERROR or similar.
8121 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
8123 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
8125 * struct.c (scm_init_struct): new file.
8127 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
8129 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
8130 (scm_list_head): added list-head for rapidly chopping argument
8131 lists off of longer lists (and similar).
8133 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
8135 * objprop.c (scm_object_property): assq the cdr of the whash
8136 handle for obj, not the handle itself.
8138 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
8140 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
8141 weak hash tables last of all marking to avoid an obscure gc bug.
8142 WARNING: circular lists stored in a weak hash table will hose us.
8144 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
8146 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
8147 new functions similar to scm_substring_move_left_x and
8148 scm_substring_move_right_x.
8150 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
8152 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
8155 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
8157 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
8159 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
8161 * strports.c (scm_strprint_obj): convenience function. C for
8162 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
8164 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
8165 removed to a separate library
8167 * init.c (scm_boot_guile): copied from guile-tcl.c.
8168 Initialization specific to tcl interpreters removed.
8170 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
8172 * ports.c (scm_ports_prehistory): size malloced here doesn't
8173 matter so long as it is non-0 (got rid of "* 4").
8175 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
8177 * gscm.h: gscm_mkarray eliminated (presumably was not being used
8178 since its definition was bogus).
8180 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
8182 * mallocs.[ch]: back again (for rx at least).
8184 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
8186 * ports.c: removed functions relating to the mapping between ports
8187 and descriptors. (That stuff is unix-specific and should be collected
8188 in a separate library).
8190 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
8191 (Tom Mckay@avanticorp.com)
8193 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
8195 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
8196 handled correctly (SCM_FREEP was applied to them) -- test for
8197 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
8198 being overwritten with #f. (brown@grettir.bibliotech.com)
8200 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
8202 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
8203 for a specific symbol or for all symbols.
8205 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
8207 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
8208 keys and weak values confused).
8210 Thu Mar 14 22:20:20 1996 Tom Lord <lord@beehive>
8212 * list.c (scm_last_pair): map '()=>'()
8214 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>
8216 * pairs.c, hashtab.c, list.c, alist.c append.c, sequences.c:
8217 Generalized assoc and hash-table functions.
8218 Factored pairs.c into multiple files.
8220 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
8222 * gscm.c (gscm_run_scm): got rid of objprop.
8224 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
8226 * genio.c (scm_getc):
8227 NOTE: fgetc may not be interruptable.
8229 * procprop.c (scm_stand_in_scm_proc):
8230 NOTE: don't use a alist here.
8231 (scm_set_procedure_properties_x): fix type checking throughout this file.
8233 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
8235 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
8236 after freeing part of the port table.
8238 Thu Feb 29 16:21:17 1996 Tom Lord <lord@beehive>
8240 * strports.c (scm_mkstrport):
8241 * vports.c (scm_make_soft_port): allocate a port table entry
8242 (possibly triggering gc) before setting the tag of the corresponding
8245 * pairs.c (scm_delq_x): never throw an error.
8247 * vectors.c (scm_make_vector): made the default vector fill argument
8248 into '() (much more useful than the previous value, "#unspecified")
8250 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
8252 * ports.c (scm_add_to_port_table): Added fields
8253 to port table entries: file_name, line_num, col.
8254 Update these in open_file, gen_getc and gen_ungetc.
8255 Added procedures to access those fields.
8257 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
8259 * procs.c (scm_make_subr_opt): new entry point for making
8262 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
8264 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
8266 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
8268 * numbers.c (scm_exact_p): This function no longer
8269 implements "integer?".
8271 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
8273 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
8274 (scm_gc_stats): return an assoc of useful data. Replaces "room"
8275 and the stats reporting formerlly built into repl.
8277 * repl.[ch]: removed.
8278 GC statistics keeping moved to gc.c.
8279 Other statistics keeping can be done from Scheme.

8292 This file is for stuff relating specifically to Scheme libraries
8295 * eval.c (scm_m_define): don't give warning about redefinition, don't
8298 NOTE: this should throw a resumable exception with parameters --
8299 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
8301 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.

8365 initialization to fix a race condition.
8367 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

8391 set the multi_byte flag correctly in symbols. This is wrong.
8392 intern_obbary_soft and msymbolize should take an extra parameter.
8393 Also, weird multibyte symbols don't print correctly.
8394 The weird symbol syntax is also a bit bogus (emacs doesn't quite
8397 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
