1 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
3 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
6 * numbers.c (big2str): Protect t from garbage collection until
7 we're done. (Thanks to Gary Houston.)
9 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
11 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
13 * Makefile.in: Regenerated.
15 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
16 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
19 Do magic to mix reads and writes on stdio FILE-based ports.
20 (Thanks to Christian Lynbech.)
21 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
23 (pre_read, pre_write): New functions.
24 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
25 local_fputs): Call them.
26 (local_fflush): Mark the port as ready for reading and writing.
27 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
28 flags on new port objects. This might not be accurate --- who
29 knows what state the FILE * is in when we get it --- but it won't
30 do extraneous calls to fflush or fseek, so it's no worse than the
31 behavior before this change.
32 * ports.h: Add comment.
34 Centralize the creation of port objects based on stdio FILE * in
35 fports.c; don't just throw them together anywhere.
36 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
37 what the rest of Guile wants. Don't set the revealed count;
38 that's only appropriate for stdin, stdout, stderr.
39 (scm_standard_stream_to_port): This function does set the revealed
41 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
42 not scm_stdio_to_port.
43 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
44 * fports.c (scm_open_file): Same.
45 * posix.c (scm_pipe): Same.
46 * socket.c (scm_sock_fd_to_port): Same.
47 * ioext.c (scm_fdopen): Same.
48 (scm_freopen): Moved from here to...
49 * fports.c (scm_freopen): ... here. This is really something that
50 munges the internals of an fport, so it should go here.
51 * fports.h (scm_stdio_to_port): Adjust prototype.
52 (scm_standard_stream_to_port, scm_freopen): New protoypes.
53 * ioext.h (scm_freopen): Prototype removed.
55 * filesys.c (set_element, get_element): This can work on both pipe
56 and file ports, so use SCM_FPORTP to typecheck, instead of testing
59 * scmconfig.h.in: Regenerated.
61 Change the definition of the functions in scm_ptobfuns so that
62 they get passed the port object, not the port's stream.
63 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
64 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
65 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
66 Pass the port itself to the scm_ptobs function.
67 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
68 scm_generic_fgets): Same.
69 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
70 getc_void_port, fgets_void_port, close_void_port): Just change the
71 argument names; these functions don't really do anything.
72 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
73 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
74 port as an argument, and use SCM_STREAM to get the stdio FILE *.
75 Also, use prototyped definitions, and get rid of the extra
77 (scm_fptob, scm_pipob): We don't need casts here any more.
78 * strports.c (prinstpt): Use prototype declarations.
79 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
80 and use SCM_STREAM to get the string info. Also, use prototyped
81 definitions, and get rid of the extra declarations.
82 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
85 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
86 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
88 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
89 scm_fgets, for consistency.
90 (scm_fptop, scm_pipob): References updated.
92 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
94 Include the source location in error messages for scripts.
95 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
96 stack is still there when we catch the error.
97 * throw.c (handler_message): If we are handling an error with a
98 message, then put together the proper arguments and call
99 scm_display_error, instead of scm_display_error_message. That
100 displays source location, if it can find it.
102 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
104 * gc.c (scm_unprotect_object): Change this so that calls to
105 scm_protect_object and scm_unprotect_object nest properly.
106 (scm_protect_object): Doc fixes.
108 * strings.c (scm_string_set_x): Require the argument to be a
109 writable string, not a substring or a symbol.
110 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
111 (Thanks to John Redford and Charbel Jacquin.)
113 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
115 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
117 * eval.c (safe_setjmp): Remove this misunderstanding.
118 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
121 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
123 * libguile.h: Mark these as C declarations, for compilation by C++
126 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
127 __cplusplus clause. I seriously doubt this ever worked the way
128 the author seems to have intended.
130 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
132 Utterly needless cleanups to hopelessly messy code.
133 * ports.c: Doc fixes.
134 (scm_fflush): Moved to ...
135 * genio.c (scm_fflush): ... here, amongst all the other port
136 method invocation functions.
137 * genio.h, ports.h: The prototype moves too.
139 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
141 * backtrace.c (display_error_body): The current frame does not
142 always have a parent frame; consider a function called directly
143 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
146 * alloca.c (alloca): Undo yesterday's changes, and simply call
147 malloc directly for storage, and abort if we don't get what we
148 want. The situation is much simpler --- just call malloc. Emacs
149 has bizarre/evil requirements (signal handlers might malloc unless
150 you set this global flag, so you have to set the flag around all
151 calls to malloc) which we are certainly not going to conform to,
152 so we can do the simple and obvious thing.
154 * coop.c (coop_condition_variable_wait): Make this function
155 static. It's only useful internally --- you should never just
156 wait on a condition variable.
157 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
159 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
161 * unif.c (scm_array_set_x): Accept any kind of number as an
162 element for a uniform vector of doubles. This is more consistent
163 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
165 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
166 works; I can't conveniently test it myself. (Thanks to Dvid
167 Tillman for the bug report.)
171 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
172 from here, not from scm_compile_shell_switches (which is a pretty
173 dumb place to do it).
174 (scm_load_startup_files): New function.
175 (scm_ice_9_already_loaded): Variable moved to here from script.c.
176 * script.c (scm_compile_shell_switches): Don't load the startup
178 (scm_ice_9_already_loaded): Variable moved.
179 * init.c (scm_load_startup_files): Prototype for new function.
180 * gh_init.c (gh_enter): Doc fix.
182 1998-10-03 <jimb@savonarola.red-bean.com>
184 Some anti-warning changes from Greg Harvey.
185 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
186 warnings when it doesn't understand our NORETURN declarations in
188 * posix.c (scm_mknod): Similar.
190 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
192 * posix.c (scm_getpwuid): If we can't find an entry, return our
193 own message, instead of using scm_syserror --- the getpwMUMBLE
194 functions don't set `errno' to anything interesting.
196 1998-10-03 <jimb@savonarola.red-bean.com>
198 Get rid of warnings from the cooperative threading system.
199 * threads.h (scm_single_thread_p, scm_yield,
200 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
201 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
202 scm_wait_condition_variable, scm_signal_condition_variable): Add
203 prototypes for these Scheme-visible functions.
204 * coop-defs.h (coop_next_runnable_thread,
205 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
206 Prototypes for these here, even though they're from iselect.c.
207 (coop_condition_variable_wait, coop_join): Add prototypes.
208 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
209 scm_threads_free_condvar): Make these smob functions static.
210 * coop-threads.h (coop_init): Give this a real prototype.
211 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
212 (coop_next_runnable_thread): No need to provide prototype; it's in
215 * scmconfig.h.in: .detarenegeR
217 * iselect.c, threads.c: Doc fixes.
219 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
221 * Makefile.in: Regenerated with a patched automake, to get
222 dependency generation right when using EGCS.
224 * inet_aton.c (inet_aton): Add prototype, to remove compiler
225 warning. (Thanks to Robert Pluim.)
227 * inet_aton.c (inet_aton): Reassure the compiler that the
228 arguments to the <ctype.h> macros are all unsigned characters, not
231 1998-10-03 <jimb@savonarola.red-bean.com>
233 Getting rid of more warnings...
234 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
235 today's change to ../configure.in.
236 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
237 * scmconfig.h.in: Regenertaded.de.,.__
238 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
239 (scm_localtime, scm_mktime): Use a const char * to manipulate the
242 * readline.c: Doc fix.
243 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
244 * readline.h (scm_filename_completion_function): Add prototype.
245 (scm_init_readline): Make this into a prototype.
247 * readline.c (scm_filename_completion_function): Use SCM_PROC to
248 declare this, instead of calling scm_make_subr manually.
250 1998-10-02 <jimb@savonarola.red-bean.com>
252 * readline.h (scm_init_readline): Add prototype for this.
253 (scm_init_readline): Make this a real prototype.
255 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
257 Warning fixes from Maciej Stachowiak:
258 * backtrace.h (scm_display_application, scm_backtrace): Add
260 * debug.c (scm_m_start_stack): Make this function static.
261 * fluids.h (scm_fluid_p): Add prototype.
262 * procprop.c (scm_i_procedure_arity): Make this function static.
263 * regex-posix.c (scm_regexp_error_msg): Make this function static.
264 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
265 * root.h (scm_dynamic_root): Add external prototype.
266 * scmsigs.h (scm_usleep): Add external prototype.
267 * script.h (scm_init_script): Use prototype, not K&R decl.
268 * stacks.h (scm_stack_id): Add external prototype.
269 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
271 1998-09-30 Mark Galassi <rosalia@cygnus.com>
273 * gh.h: took out the definitions of vset and vref, since they are
274 replaced by the proper vector routines that correspond to the R4RS
277 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
279 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
280 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
281 third argument, a C expression that should result in a SCM value,
282 which is used to initialize the variable. Reimplemented
283 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
286 * version.h (scm_libguile_config_stamp): Add prototype.
287 (From Maciej Stachowiak.)
289 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
291 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
292 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
294 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
296 * print.c (scm_iprin1): Rather than having one i, and using it in
297 several places, declare a fresh i local to each block where it is
298 used, and give it a signedness appropriate to its use in each case.
301 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
304 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
305 signed/unsigned clashes.
307 * posix.h (scm_tmpnam): Added prototype.
309 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
310 scm_make_subclass_object): Add external prototypes.
312 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
313 comparison is okay here.
315 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
317 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
318 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
320 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
323 * load.c (swap_port): Make this function static.
325 * load.c (scm_search_path): Make max_path_len and max_ext_len
326 unsigned, since they're compared against string sizes.
328 * load.c (init_build_info): Make i unsigned.
330 * ioext.h (scm_read_line): Add prototype.
332 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
333 scm_hash_fn_remove_x): Make hash bucket index local variable k
334 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
335 accurately as possible.
337 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
338 comparisons, and range checking to make sure those casts are
341 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
342 signed/unsigned comparisons.
344 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
345 avoid signed/unsigned comparisons.
346 * smob.h (scm_numsmob): Change extern declaration to match.
348 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
349 avoid signed/unsigned comparisons.
350 * ports.h (scm_numptob): Change extern declaration to match.
351 (scm_current_load_port, scm_set_port_line_x,
352 scm_set_port_column_x): New prototypes.
354 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
355 test code, and it causes warnings.
357 * gh.h (gh_int2scmb, gh_uniform_vector_length,
358 gh_uniform_vector_ref): Added prototypes.
360 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
361 debugging support unconditionally. That's backtrace.c, stack.c,
362 debug.c, and srcprop.c.
363 (EXTRA_libguile_la_SOURCES): Omit those from here.
364 * Makefile.in: Regenerated.
366 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
368 * options.c (scm_options): Bugfix: Allow empty list of options!
370 * debug.c, debug.h (scm_single_step): Removed.
371 (scm_with_traps): New procedure. This procedure could easily be
372 written in Scheme but needs to be highly optimized.
374 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
376 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
377 Check SCM_TRAPS_P before trapping.
379 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
381 Changes to avoid signed/unsigned comparison warnings.
382 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
383 (scm_gc_sweep): Make n and j local to the blocks they're used in,
384 so they can have appropriate types for each application. Make i
385 signed. Use initializers in some spots. I'll probably pay for
387 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
388 (scm_must_realloc): Make nm unsigned.
389 (init_heap_seg): Make new_seg_index and n_new_objects signed.
390 (scm_init_storage): Use prototype-style definition, and make the
392 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
393 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
395 * filesys.c (scm_readlink): Make local vars rv and size ints, to
396 avoid signed/unsigned comparison warnings, and because the return
397 value of readlink may be -1. Don't bother casting the third
398 argument to readlink.
400 * filesys.c (scm_dirname, scm_basename): Move these to their own
401 page, at the end of the file.
402 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
404 * eval.h (scm_eval_options_interface): Add external prototype for this.
405 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
407 * eval.c (scm_lookupcar1): Make this static.
409 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
410 Make these prototype declarations, not K&R-style.
412 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
413 unsigned comparison warning.
415 * appinit.c: File removed. It had a single function in it, empty,
416 whose reason for existence is explained in no documentation or
417 comment. I think it's there as a default for some Tcl-style
418 initialization, but Tcl abandoned that approach a while ago.
419 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
420 (BUILT_SOURCES): Remove appinit.x.
421 * Makefile.in: Regenerated.
423 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
425 * Makefile.in: Regenerated using the last public version of
426 automake, not the hacked Cygnus version.
428 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
430 Remove Totoro kludge.
431 * Makefile.in, scmconfig.h.in: Regenerated.
432 * init.c, readline.c: Don't check if TOTORO is #defined.
434 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
436 * Makefile.am: Adjust for new thread configuration system.
437 (INCLUDES): Include the value of THREAD_CPPFLAGS.
438 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
440 (THREAD_LIBS): Definition deleted; automake will generate such
441 things automatically.
442 * Makefile.in: Regenerated.
444 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
446 Simplify smob and port marking; set the mark bit in the generic
447 marking code, and make marker routines only responsible for
448 turning up outgoing pointers.
449 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
450 before calling the marking function. Don't call the marking
451 function if it's zero.
452 * markers.c (scm_mark0): Just return #f. This function isn't
453 necessary at all now, but it's harmless to call it. We'll leave
454 it in so other folks' code doesn't croak at link time.
455 (scm_markcdr): Don't call SCM_SETGC8MARK.
456 * async.c (mark_async): Don't call SCM_SETGC8MARK.
457 * dynl.c (mark_dynl_obj): Same.
458 * root.c (mark_root): Same.
459 * srcprop.c (marksrcprops): Same.
460 * unif.c (markra): Same.
461 * variable.c (scm_markvar): Same.
462 * ports.c (scm_markstream): Same.
463 (void_port_ptob): Specify zero for our marking function.
464 * debug.c (debugobjsmob): Same.
465 * dynwind.c (guardsmob): Same.
466 * filesys.c (dir_smob): Same.
467 * fluids.c (fluid_smob): Same.
468 * fports.c (scm_fptob, scm_pipob): Same.
469 * mallocs.c (mallocsmob): Same.
470 * regex-posix.c (regex_t_smob): Same.
471 * smob.c (freecell, flob, bigob): Same.
472 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
473 * throw.c (jbsmob, lazy_catch_funs): Same.
475 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
477 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
478 scm_copy_tree on code in order not to let memoized code to leak
479 out. Thus, scm_copy_tree needs to copy vectors as well since
480 quasiquote can introduce evaluated code also inside vector
483 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
485 * eval.c (scm_copy_tree): Removed ability to copy vectors.
487 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
488 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
491 * unif.c: Say that ivect and uvect are of type signed and unsigned
492 long instead of int in commentary so that it correctly describes
495 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
497 * stime.c: Removed declaration of strptime. (It should be
498 declared by the system headers. If it turns out that some systems
499 don't, we'll handle that then.) (Thanks to Greg Troxel.)
501 * stime.h: Renamed TIMEH --> STIMEH
503 * backtrace.c (scm_display_error, scm_display_backtrace): In order
504 to increase portability, don't use structure assignment.
505 (Thanks to Nicolas Neuss.)
507 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
509 (finalize_fd_sets): Added empty statement after last case label.
510 (Thanks to Nicolas Neuss.)
512 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
515 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
517 * init.c, readline.c: OK, I won't have these readline.x bug
518 reports anymore. We've had them since April. The current reason
519 is a completely unintelligible failure of totoro.red-bean.com to
520 do the test for rl_getc_function in libreadline correctly. This
521 kludge overrides the test if we're on totoro so that the snapshot
522 generation process can work.
524 * readline.c: Define a strdup replacement if not existent on system.
526 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
528 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
529 This change makes scm_make_vector R5RS compatible. We cannot keep
530 the third argument since people want to be able to deduce the form
531 of the C function call only by looking at R5RS. (At the same time
532 we have removed some unnecessary complexity!)
534 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
535 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
536 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
537 argument in call to scm_make_vector.
539 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
541 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
542 This macro is useful in applications.
544 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
546 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
547 (scm_parse_path, scm_search_path): New Scheme level procedures.
549 * load.h (scm_internal_parse_path, scm_parse_path,
550 scm_search_path): Declared.
552 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
554 * filesys.c (dirname, basename): New procedures.
556 * init.c (scm_boot_guile_1): Removed condition around
559 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
560 new data type (guards) for representation of C level guards and
561 data on the wind chain.
562 (scm_internal_dynamic_wind): New function.
564 * dynwind.h: Declare scm_internal_dynamic_wind.
566 * root.h (scm_root_state): Added scm_cur_loadp.
568 * root.c (mark_root): Added comment about cur_loadp.
570 * load.c: #include "dynwind.h";
571 (scm_primitive_load): Use scm_inner_dynamic_wind to update
574 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
576 * ports.c (current-load-port): New procedure.
578 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
580 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
581 not a tty, return #f.
583 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
584 to Julian Satchell and Roland Kaufmann.)
586 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
587 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
589 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
591 * debug.h, debug.c (scm_start_stack): New function. Implements
592 the guts of old scm_m_start_stack.
594 * debug.c (scm_m_start_stack): Use scm_start_stack.
596 * init.c (scm_start_stack, scm_restart_stack): Renamed to
597 start_stack and restart_stack. (These have static scope.)
599 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
601 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
602 readline functions to come in release 2.3. (Thanks to Chet
604 (handle_errors): Use the above functions.
606 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
608 * readline.c: Improvements for readline support: Handle errors
609 better; Implement before-read-hook.
611 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
613 * init.c (scm_boot_guile_1), readline.c: Test for
614 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
615 assure that we have version >= 2.1.)
617 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
619 * readline.c (scm_readline): Defer interrupts while we're calling
622 * readline.c (scm_add_history): Bugfix: Do strdup before giving
623 away the string to add_history.
624 (completion_function): Do completion for readline. (Thanks to
626 (scm_filename_completion_function): New procedure: Filename
628 (current_input_getc): New function. Use this one instead of
629 standard getc from readline.
631 * throw.c, throw.h (scm_handle_by_throw): New function: This
632 handler throws errors to next handler on the dynwind chain.
634 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
636 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
639 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
641 * procprop.c (scm_i_procedure_arity): New function. Returns arity
643 (scm_procedure_properties): Modified to return arity together with
645 (scm_procedure_property): Added the read-only property `arity'.
646 (scm_set_procedure_property_x): It is an error to set the `arity'
649 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
650 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
652 * procprop.h (scm_sym_arity): New symbol.
654 * objects.c (scm_set_object_procedure_x): New procedure: Use this
655 to set the dispatch procedure of an operator or entity object.
657 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
658 Made procedure slots read-only.
660 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
661 scm_tcs_cons_gloc case in zero args switch; Fixed args
662 construction for operators in scm_tcs_cons_gloc case in two args
665 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
667 * fluids.c: Removed use of assert.h (in order to avoid
670 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
672 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
674 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
675 change makes the evaluator safer at the cost of evaluation speed.
676 It handles the case when the user has added a non-immediate
677 improper end of the application form, e.g., `(+ 0 . x)'.
678 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
679 minimize the extra cost as much as possible. The new code is
680 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
681 problem with structs planted directly in the code (e.g. by a
682 macro). This no longer causes segmentation fault. (Thanks to
685 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
686 arg `proc' in order to be able to throw errors; New argument
689 * Removed extra #include "debug.h"
691 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
693 * scmsigs.c: Declare usleep as returning void on some systems.
694 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
697 * coop.c (usleep): Return void on some systems.
699 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
701 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
703 * coop.c: Changed return type of usleep to int.
705 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
706 isn't found in the OS.
708 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
709 isn't enabled. (Thought that I had made this change ages ago...)
711 * iselect.c: Declare bzero if not defined by OS.
713 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
715 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
716 condition. (Thanks to John Tobey.)
718 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
719 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
722 * __scm.h: Start the long-term project of moving to POSIX threads.
723 Phase 1: Classification of all critical sections.
724 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
725 for A sections. (See comments in __scm.h for details.)
727 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
728 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
730 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
732 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
733 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
734 (libpath.h, versiondat.h): Replaced dependency on Makefile with
735 dependencies on $(srcdir)/Makefile.in
736 $(top_builddir)/config.status in order to avoid circularity.
738 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
739 from argc if argc was 0 initially.
741 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
742 in generation of libpath.h.
744 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
746 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
747 libguile from 2 to 3.
749 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
751 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
753 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
755 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
756 scm_set_port_column_x, scm_port_filename,
757 scm_set_port_filename_x): Removed optional arguments. Added
758 proper argument checking.
760 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
761 stack size in machine words.
763 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
764 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
765 to Ole Myren Röhne.)
767 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
769 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
770 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
772 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
775 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
776 procedure apply: Copy argument lists before pushing them unto the
777 environment so that the environment won't get mutated due to
778 manipulation of procedure arguments. This should perhaps be
779 regarded as a temporary solution until someone finds a more
780 efficient one. (Thanks to Maciej Stachowiak.)
782 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
784 * script.c (scm_compile_shell_switches): Use "guile" as default
785 zero arg if argc is NULL.
787 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
789 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
790 is zero. (Thanks to Dirk Herrmann.)
792 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
794 * ports.c (scm_add_to_port_table): First line is now line 0
795 (was 1). (Interface changed according to suggestion by Per
798 * backtrace.c (display_header): Add 1 to line and column numbers
799 when presenting them to the user.
801 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
802 from debug.c --> eval.c
804 * eval.h, eval.c (scm_eval_options_interface): New options
806 (SCM_EVAL_STACK): New option: Size of newly created stacks,
807 i.e. stacks for new threads.
809 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
811 * eval.c (unsafe_setjmp): Removed with #if 0.
813 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
816 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
817 to avoid compiler warnings.
819 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
821 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
823 * throw.c (handler_message): Print message on current error port
824 instead of default error port. (Thanks to Maciej Stachowiak.)
826 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
828 * ports.c (scm_add_to_port_table): allocate in units of
829 struct scm_port_table *, not struct scm_port_table.
830 * posix.c (scm_close_pipe): remove the port from the port table
832 Thanks to Rob Engle for both fixes.
834 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
836 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
837 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
839 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
841 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
843 * backtrace.c (display_error_body, display_backtrace_body),
844 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
845 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
846 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
847 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
850 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
851 don't receive the jmpbuf arg anylonger.
852 (scm_catch): Don't accept a #f tag.
853 (scm_throw): Check that key is a symbol.
854 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
856 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
858 * async.c (async_pending): Removed declaration.
860 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
862 * dynwind.c (scm_wind_chain): New debug function.
864 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
865 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
866 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
867 extra layer of functions around the body and handler of a thread.
868 This extra layer makes sure that the handler is called in the
869 dynamic context of the surround (= empty dynwind list), but under
870 the *dynamic root* of the body. We can not use the dynamic root
871 of the surround since that root belongs to another thread => stack
872 is not handled correctly. It may seem ugly to use this extra
873 layer, but the extra cost in terms of execution time is really
874 negligible compared to the total amount of time required to create
875 a thread, and it would reduce maintainability to duplicate the
876 crucial and complicated steps performed by cwdr.
878 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
879 (SCM_ALLOW_INTS): Added thread switching code before interrupts
880 get re-enabled. The important effect of this is that interrupts
881 are blocked during thread switching so that thread data structures
882 don't risk getting messed up by an unfortunate signal.
883 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
884 seems to do more aggressive optimization which actually move
885 instructions around in these macros in a fatal way. Therefore:
886 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
887 just superstitious...)
888 (SCM_TICK): Maybe do a context switch and take care of asyncs.
889 This macro should be used instead of SCM_ASYNC_TICK since the
890 latter doesn't do context switches any more.
892 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
893 instead of SCM_ASYNC_TICK.
895 * coop.c, iselect.c: Since thread switches are now performed with
896 interrupts masked, we can't use the old mechanism of delivering
897 signals immediately when they arrive. Signals must instead be
898 delivered when the asyncs run *after* the end of the critical
899 section in scm_internal_select. But this also means after context
900 switch so that the signal will be delivered to a different thread.
901 To avoid this, I have changed the protocol of
902 coop_wait_for_runnable_thread and friends so that they are allowed
903 to return the original thread. So, if a signal arrives during
904 scm_internal_select, we won't any longer be forced do a context
905 switch, but can remain in the same thread and deliver the signal
908 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
909 scm_asyncs_pending and made it global.
911 * iselect.c: Small fixes.
913 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
914 coop_condition_variable_init, coop_condition_variable_wait,
915 coop_condition_variable_signal): Changed return type from `void'
916 to `int'. This is to adhere closer to the pthreads interface.
917 This, in turn, is part of an attempt to provide C versions of the
918 mutex and condition variable primitives which can be part of a
919 frontend to COOP or pthreads.
921 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
922 coop_condition_variable_destroy): New functions.
924 * coop-threads.c (scm_wait_condition_variable): Use
925 coop_condition_variable_wait_mutex.
927 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
928 Definitions moved to coop-defs.h.
930 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
931 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
932 scm_cond_destroy): New C interface to mutecis and cond vars.
934 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
936 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
938 * iselect.c: Now several threads can wait on the same file
939 descriptor. The behaviour is compatible with OS select: All
940 threads waiting for the fd return with the same status.
942 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
944 * coop-threads.c, threads.h (scm_spawn_thread): New function.
945 Can spawn a thread from application C code.
947 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
949 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
950 gh_doubles2scm): New functions.
952 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
954 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
955 commented-out version of gh_eval_str()
957 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
959 * socket.c (scm_bind): free soka after use.
961 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
963 * stime.c (tzvar): new variable.
964 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
965 avoid memory leaks when allocating.
967 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
969 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
972 * gc.c, tags.h: Doc fixes.
974 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
976 * eval.c (macro-eval!): Removed. This function was a design bug.
977 It allowed memoized code to leak out to the scheme level. Most
978 things that you could do with `macro-eval!' can be done with
981 1997-12-20 Tim Pierce <twp@skepsis.com>
983 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
984 scm_fgets now depends on ftell(3) to know how many bytes were
987 1997-12-15 Tim Pierce <twp@skepsis.com>
989 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
990 dealing with strings.
992 1997-12-13 Tim Pierce <twp@skepsis.com>
994 Make %read-line more suitable for implementing read-line efficiently.
995 * ioext.c (scm_read_line): Strip the terminating newline from a
996 string, and return a cons of the string and its terminator.
998 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
999 of the string that is read is stored in this memory location.
1000 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
1001 * genio.c, genio.h (scm_do_read_line): Update caller.
1002 * ports.h (scm_ptobfuns): Update typedef.
1003 * fports.c (scm_fptob, scm_pipob): Update struct.
1005 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1007 * filesys.c (set_element): Return file descriptor.
1008 (fill_select_type): Return the highest file descriptor.
1009 (scm_select): Tell select about the highest file descriptor. On
1010 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
1011 Therefore the extra overhead for calculating the maximum fd seems
1012 to be more than compensated. Is this correct? In any case,
1013 scm_internal_select will be much faster with this info.
1014 (scm_select, fill_select_type, set_element): Don't accept any kind
1015 of object in the file descriptor list or vector.
1017 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1019 * iselect.c (finalize_fd_sets): Bugfix.
1021 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1023 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1024 when using scm_internal_select (since we might switch to another
1027 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1029 * simpos.c (scm_system): always define: use sysmissing if not
1030 available. Check for HAVE_SYSTEM instead of _Windows (does
1031 Windows lack system or does it have an unusable one?).
1032 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1033 Let the argument be optional: if not supplied, call system(NULL).
1035 * ports.c (scm_close_port): relax the type check from OPPORTP to
1036 PORTP; closing a closed port is allowed.
1038 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1040 * fports.c (scm_fgets): Return if the last char in a chunk is
1041 newline. When fgets returns a string whose length is `size-1', it
1042 is ambiguous whether a whole line was retrieved, so we must check
1043 explicitly whether a line terminator is present.
1045 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>

1128 replacement in iselect.c.
1129 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1130 coop_join): If GUILE_ISELECT enabled, use
1131 coop_wait_for_runnable_thread instead of
1132 coop_next_runnable_thread.
1133 (usleep, sleep): New replacements for system functions if
1134 GUILE_ISELECT is enabled.
1136 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1138 * coop-defs.h (coop_t): Added fields used by scm_internal_select.

1153 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1154 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1155 and scm_must_free, since ultimately the string returned will be copied
1156 by scm_makfrom0str anyway. Also, read any characters that may have
1157 been pushed onto the port with scm_ungetc.
1158 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1159 * ioext.c (scm_read_line): Free string after Guilifying it.

1175 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1176 and to invoke scm_shell().
1177 (gh_launch_pad): took out the loading of boot-9.scm from here,
1178 since it is probably best to let the user control that. In fact,
1179 gh_repl() now invokes scm_shell() which does that.
1181 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1183 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()

1210 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when

1218 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1220 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An

1230 scm_close_all_ports_except, scm_set_current_output_port,
1231 scm_set_current_error_port): Likewise
1232 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,

1273 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1275 * gh_data.c (gh_vector_set_x): changed name to make it consistent

1304 * tags.h (scm_tc7_substring): Changed the comment and code to
1305 conform with the changes below. Folks! We have suddenly two new

1370 * gh_test_c.c (c_vector_test): some improvements on the vector
1373 * gh.h (gh_vector): this used to exist but do the wrong thing.
1374 Now it (almost) does the right thing, though it takes a list
1375 instead of the individual arguments. I need to see how it could
1377 (gh_list_to_vector): added this function as a macro. Corresponds
1378 to Scheme's (list->vector ...).

1437 transformers. (They are always: exp env.); Bugfix: Unmemoize
1438 transformer source with correct environment.

1448 (scm_internal_cwdr): New function to perform the function of cwdr
1449 but take args that are more useful to C code. Also, the handler
1450 is now invoked *outside* of the new dynamic root, like the docs

1452 is responsible for using a handler that does not throw, if he
1454 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1455 * root.h (scm_internal_cwdr): New prototype.
1457 Even more but risky streamlining:
1459 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1460 allocation of the jumpbuf of a root continuation. The changes
1461 below are controlled by it. They are now deactivated.
1462 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1463 the JMPBUF of the scm_rootcont to NULL before returning.
1465 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1466 when they are non-NULL.

1487 one or when it returns #f.
1488 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1489 Accept a port/print-state pair in addition to just a port.
1490 (scm_prin1): Don't return the print_state to the pool when it has
1492 (scm_printer_apply): Set `revealed' field of print_state to true.
1493 (scm_init_print): Set scm_print_state_vtable.

1503 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1505 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1506 was looping endlessly.
1508 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1510 * strports.c (scm_eval_string): Don't close the port.
1512 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1513 former returns a nice normal integer. (Thanks to Daniel
1516 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1518 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1519 makefile variable as a build parameter called LIBS. The
1520 build-guile program will use this, for the time being.
1521 * Makefile.in: Regenerated.
1523 Thanks to Shiro Kawai:
1524 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1525 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1528 * Makefile.in: Regenerated with automake 1.2a.
1530 * script.c (scm_compile_shell_switches): If we hit the -c or --
1531 arguments, don't set the car of (command-line) to scm_usage_name,
1532 the prettified name of the guile executable; give it the full
1533 path, the way shells usually handle $0.
1535 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1537 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1538 Scheme-level name `array-map' and renamed `serial-array-map' to
1539 `serial-array-map!'.
1541 * backtrace.c: Introduced exception handlers which now enclose
1542 `display-error' and `display-backtrace' so that error reporting
1543 won't get into infinite loops if an error occurs during displaying
1544 of the error. This can very easily happen with user supplied
1545 print call-back routines.
1547 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1549 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1550 the names `serial-array-map' and `array-map' should be removed.)
1552 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1554 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1555 Added #include "objects.h"
1557 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1558 Add #include "feature.h".
1560 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1561 (modinclude_HEADERS): Added objects.h.
1563 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1564 This test is needed at many places in the code and should be
1565 abstracted. (Motivated by the need of this test in libguiletk.)
1567 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1568 (scm_eval_string), load.c (scm_primitive_load,
1569 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1570 Use SCM_EOF_OBJECT_P.
1572 * eval.c (scm_init_eval): Add feature `delay'.
1574 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1576 * scmhob.h: Removed.
1578 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1580 * list.h (SCM_LISTn): New macros. Make list creation in C code
1581 prettier. The idea comes from STk.
1583 * sequences.h, sequences.c, append.h, append.c: Removed. These
1584 files implemented non-R4RS operations which would encourage
1585 non-portable programming style and less easy-to-read code.
1587 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1590 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1591 sequences.h, #include append.h.
1593 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1596 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1598 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1600 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1602 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1604 * eval.c: Added #include "objects.h"
1606 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1609 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1610 adjacent smob numbers.
1612 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1614 * procprop.h: Added declaration of scm_i_inner_name.
1616 * gsubr.c: New global symbol scm_i_inner_name.
1618 * debug.c (scm_procedure_name): Try procedure property
1619 `inner-name' if `name' fails.
1621 * print.c (scm_iprin1): Use scm_macro_name.
1623 * eval.c (scm_m_define): Give names to macros as well; Only the
1624 first top-level definition gives a procedure/macro a name.
1625 Otherwise confusing names can turn up in backtraces.
1626 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1627 `name'; Give names to macros as well.
1629 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1630 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1633 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1635 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
1637 (prinmacro): Removed. The code has been moved/merged into print.c
1638 in order to decrease code redundancy. We want macros to print in
1639 a way equivalent to procedures, and it would be silly to duplicate
1640 the required code. (We don't want to maintain two places.)
1641 (macrosmob): Print field is now a NULL pointer.
1643 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1644 scm_macro_transformer): New prototypes.
1645 (scm_tc16_macro): Declared.
1647 * * print.c (scm_iprin1): Added code for printing of macros. Macros
1648 are now printed in a way equivalent to procedures.
1650 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1652 * procs.h (scm_closure_p): Added declaration.
1654 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1656 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
1657 Shouldn't pass "heap" as the subr name.
1659 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1661 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
1662 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
1663 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1664 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1665 SCM_BOOL_T. Any non-false value is true.
1667 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1669 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1670 scm_gensym): Added prototypes.
1672 * symbols.c (scm_gensym): New function. This will speed up
1673 certain types of applications (such as macro systems) which
1674 generate lots of symbols.
1676 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1678 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
1680 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
1682 * unif.c (scm_shap2ra): tighten the checking of the array dimension
1683 specifier, since (2) or (2 . 3) would cause SEGV.
1684 (scm_transpose_array): more argument checking fixes.
1686 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1688 * Makefile.in: Regenerated.
1690 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1692 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
1694 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1696 * error.c, error.h (scm_error_callback): Removed (see NEWS).
1698 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
1700 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
1701 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
1704 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
1705 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1706 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
1707 scm_array_p, scm_array_rank, scm_array_dimensions,
1708 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
1709 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
1710 scm_array_prototype): Added case scm_tc7_wvect.
1712 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
1714 * errno.h: prototype for scm_strerror.
1715 * error.c (scm_strerror): new procedure.
1717 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1719 * list.c (scm_list_append_x): Allow non-pair as last argument.
1720 This is consistent with the R4RS append and is probably the
1721 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1723 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1725 * stime.h: prototype for scm_times.
1726 * stime.c (scm_times): new procedure.
1727 * ioext.c (scm_fseek): if the first argument is a file descriptor
1729 (scm_ftell): if the first argument is a file descriptor call lseek
1731 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
1732 * filesys.c (scm_chmod): if the first argument is a file descriptor,
1734 (scm_chown): if the first argument is a port or file descriptor,
1736 (scm_truncate_file): new procedure.
1737 Add DEFER/ALLOW INTS to a few other procedures.
1738 (scm_fsync): new procedure.
1739 (scm_open_fdes): new procedure.
1740 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
1742 (scm_fcntl): the first argument can now be a file descriptor. The
1743 third argument is now optional.
1745 * posix.c (scm_execl, scm_execlp): make the filename argument
1746 compulsory, since omitting it causes SEGV.
1747 (scm_sync): return unspecified instead of #f.
1748 (scm_execle): new procedure.
1749 (environ_list_to_c): new procedure.
1750 (scm_environ): use environ_list_to_c. disable interrupts.
1751 (scm_convert_exec_args): take pos and subr arguments and
1752 improve error checking.
1754 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1756 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1757 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1758 argument to SCM_ASSERT. Furthermore, the name of the function
1759 should be passed as first argument when signalling
1760 SCM_WNA. (Thanks to Thomas Morgan)
1762 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1763 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1764 dispatches on the number of actual args has a default case
1765 reporting an internal error. This is a vestige from a version
1766 that mallocated a SCM vector to hold the arguments. In the
1767 current version this check is too late: if it ever happens we will
1768 have already overstepped the bounds of the array.
1770 Also, the patch [...] adds a check for too many actual arguments."
1772 mdj: Removed check for "internal programming error".
1774 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1776 * gh_io.c (gh_write): New function.
1778 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
1779 throw.c (scm_internal_stack_catch): New sibling to the other catch
1780 functions. Code moved from gh_eval.c.
1781 throw.h: Added header.
1782 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
1783 scm_internal_stack_catch.
1785 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1787 * ioext.h: fix up prototypes.
1788 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
1789 Scheme name is now dup->fdes.
1790 (scm_dup_to_fdes): make the second argument optional and
1791 fold in the functionality of scm_primitive_dup.
1792 (scm_primitive_dup): deleted.
1794 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1796 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
1797 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
1798 ultrix are defined. Use setvbuf instead of setbuf.
1799 (scm_setvbuf): new procedure.
1800 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
1801 (scm_setfileno): moved from ioext.c.
1802 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
1803 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
1805 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1807 * fluids.c (scm_fluid_p): New function.
1808 * fluids.h (scm_fluid_p): New prototype.

1812 * print.c (scm_iprin1): Enter printed structures into the print
1813 state as nested data while they are printed.
1814 (print_state_fluid, print_state_fluid_num): New variables.
1815 (scm_init_print): Initialize them.
1816 (scm_iprin): If print_state_fluid carries a print_state, use that
1817 instead of creating a new one.
1818 (scm_printer_apply, apply_stub, struct apply_data): New
1819 definitions to help with calling printer functions written in
1821 * print.h (scm_printer_apply): New prototype.
1823 * struct.c (scm_print_struct): Use scm_printer_apply to call the
1824 user defined struct printer.
1826 * dynwind.c (scm_dowinds): Handle fluids on the wind list.
1827 * fluids.h (scm_internal_with_fluids, scm_with_fluids,

1830 scm_swap_fluids, scm_swap_fluids_reverse): New functions.
1832 Fri Jul 25 12:05:46 1997 Marius Vollmer <mvo@zagadka.ping.de>
1834 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
1835 SCM_ASSERT: arg comes before pos.
1837 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1839 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
1840 to a list of length zero correctly.
1842 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1844 Supply an `fgets' method for port objects to do fast line i/o.
1845 * ioext.c (scm_read_line): New function.
1846 * genio.c (scm_gen_read_line): New function.
1847 * fports.c (scm_fgets): New function.
1848 (scm_fptob, scm_pipob): Add scm_fgets method.

1856 Mon Jul 21 04:03:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1858 * ioext.h: removed scm_duplicate_port prototype.
1860 * ioext.c (scm_primitive_dup2): return the new file descriptor
1861 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
1863 (scm_fdopen): bug fix: don't try to make port unbuffered until its
1864 stream has been set.
1865 (scm_duplicate_port): deleted, there's now an implementation in
1867 (scm_primitive_dup2): do nothing if newfd == oldfd.
1869 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
1871 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
1874 * ioext.h: new prototypes.
1875 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
1877 * fluids.c (next_fluid_num): don't do
1878 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
1880 * ports.h: prototypes too.
1881 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
1883 * fports.h: prototype too.
1884 * fports.c (scm_evict_ports): moved from ioext.c.
1886 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
1888 * ports.c (scm_close_port): return a boolean instead of unspecified.
1889 throw an error if an error other than EBADF occurs.
1891 * filesys.h: scm_close prototype.
1892 * filesys.c (scm_close): new procedure, can close file descriptors
1893 and ports (scsh compatible).
1895 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
1898 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
1900 * fluids.c, fluid.h: New files.
1901 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
1902 (modinclude_HEADERS): Added "fluids.h"
1904 * init.c: Include "fluids.h". (scm_boot_guile_1): Added call to
1905 scm_init_fluids to initialize the fluid machine.
1906 (scm_start_stack): Initialize the fluids of the first root with
1907 scm_make_initial_fluids.

1910 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
1911 (scm_make_root): Call scm_copy_fluids to make fluid bindings
1912 unique for the new root when it has a parent.
1914 * smob.h: Include "libguile/print.h" to make scm_print_state
1917 * dynl.c (free_dynl_obj): New function to free the dynamic object
1918 data. (dynl_smob): Use it.
1919 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
1920 the dynamic object data below the linking of the object to avoid
1921 memory leak when the linking code throws an error. Now the code
1922 leaks a whole dynamically linked library when must_malloc throws,
1923 but that should be much less likely.
1925 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
1927 Changes to compile under gnu-win32, from Marcus Daniels:
1928 * stime.c (tzset): If tzset isn't provided, make it a NOP.
1929 (scm_localtime): Change SCM_EOF to SCM_EOL.
1930 (scm_mktime): Likewise.
1931 * socket.c: Don't include sys/un.h unless autoconf tells
1932 us Unix domain sockets are available.
1933 (scm_fill_sockaddr): Ignore Unix domain code.
1934 (scm_addr_vector): Likewise.
1935 (scm_init_addr_buffer): Likewise.
1936 (scm_socketpair): Don't include unless socketpair was

1939 * scmsigs.c (scm_pause): Don't include unless pause was found
1941 * posix.c (scm_getgroups): Don't include unless support function
1942 was found during autoconf (in this case, getgroups).
1943 (scm_setpwent): For setpwent.
1944 (scm_setegid): For setegid.
1945 * net_db.c (scm_inet_netof): Don't include unless support
1946 function was found during autoconf (in this case, inet_netof).
1947 (scm_lnaof): For inet_lnaof.
1948 (scm_inet_makeaddr): For inet_makeaddr.
1949 (scm_getnet): For getnetent, getnetbyname, getnetbyaddr.

1960 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
1961 scm_misc_error, not SCM_EOF.
1963 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
1964 arguments for formatting the error message, not SCM_BOOL_F. I
1965 think this is left over from the (eq? '() #f) days.
1967 * read.c (recsexpr): Give this a dummy definition if
1968 DEBUG_EXTENSIONS isn't #defined.
1970 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
1972 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
1975 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>

1980 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
1982 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
1983 alloca.lo will be included in @LIBLOBJS@. Something better than
1984 this should be possible.
1985 * Makefile.in: Regenerated.
1987 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1989 * simpos.h: prototype for scm_primitive_exit.
1990 * simpos.c (scm_primitive_exit): new procedure, terminates the
1991 process without unwinding the stack.
1993 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
1995 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
1996 argument and logior its components together, so the user doesn't
1997 have to do this explicitly. Also, if regexp/basic is supplied, then
1998 turn off REG_EXTENDED.
1999 (scm_init_regex_posix): New regexp/basic symbol.
2000 (REG_BASIC): #define this if it is not already present.
2002 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2004 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
2005 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
2006 (CLEANFILES): New target, clean versiondat.h, libpath.h.
2007 (DISTCLEANFILES): New target, clean *.x.
2008 * Makefile.in: Regenerated.
2010 Tue Jun 24 00:29:07 1997 Jim Blandy <jimb@floss.red-bean.com>
2012 * script.c (scm_compile_shell_switches): Add 1997 to copyright
2013 years in usage message.
2015 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
2016 * Makefile.in: Regenerated.
2018 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
2019 flag; I don't think we support it.
2020 (scm_make_regexp): Make sure the user doesn't pass the
2023 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
2025 (scm_init_regex_posix): Define constants for the REG_mumble flags;
2026 name them according to the SCSH convention: regexp/mumble.
2028 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
2030 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
2032 * Makefile.am (libpath.h): Include the values of all the standard
2033 Makefile directory variables. Print a message, but don't print
2035 (versiondat.h): Print a message, but don't print all the commands.
2036 * load.c: #include "alist.h".
2037 (init_build_info): New function.
2038 (scm_init_load): Call it.
2039 * Makefile.in: Regenerated.
2041 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
2043 * root.c: Establish a reliable catch-all handler for the new root.
2044 After all the Scheme handler function might signal an error too,
2045 and we don't want to lose that.
2046 (cwdr_inner_body): Renamed from cwdr_body.
2047 (cwdr_outer_body): New function, to establish the user's handler,
2048 and pass control to cwdr_inner_body.
2049 (cwdr): Establish the reliable catch-all handler here, and pass
2050 control to cwdr_outer_body.
2051 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
2052 the user's handler through to cwdr_outer_body.
2053 * throw.c (scm_handle_by_message): Move guts into....
2054 (handler_message): New static function.
2055 (scm_handle_by_message_noexit): New function.
2056 * throw.h (scm_handle_by_message_noexit): New prototype.
2058 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
2059 across this. Only works on GCC. Otherwise, we hope for the best.
2060 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2061 the feeling that real thread systems will not need this...
2063 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2065 Try to detect when people are using one version of libguile and a
2066 different version of ice-9. People have been skewing things and
2067 sending in bug reports.
2068 * Makefile.am (versiondat.h): New file to generate.
2069 * version.c: #include "versiondat.h", to get version info.
2070 (scm_libguile_config_stamp): New function.
2071 * script.c: #include "version.h".
2072 (scm_compile_switches): Call scm_version to get version number.
2073 * scmconfig.h.in, Makefile.in: Regenerated.
2074 * Makefile.in: Regenerated.
2076 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
2077 primitive definitions under their Scheme names.
2079 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2080 1:2. Helps avoid confusion between installed and uninstalled libs.
2082 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2085 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2086 backslash from definition; this should be used like: GDB_INTERFACE;
2088 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2090 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
2091 new port unbuffered until its stream has been set.
2093 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2095 * ports.h: new prototype.
2096 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
2098 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
2100 Make things compile neatly under Sun's C compiler.
2101 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
2102 * extchrs.c (xmbtowc): Make the second arg a normal char, not
2103 unsigned, because that's what the ANSI function takes.
2104 * extchrs.h (xmbtowc): Corresponding change to prototype.
2105 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2107 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2108 argument plain char *.
2109 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2111 * tag.c (scm_tag): Remove unreachable statement.
2112 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2113 top of the word, it should be unsigned.
2115 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2116 is defined, to avoid warnings; it's only used in the
2117 conflict-checking code. Which might go away anyway.
2118 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2119 conditionals; put the label definition in an #if too, to stifle
2122 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2123 ChangeLog-threads in the distribution.
2124 * Makefile.in: Regenerated.
2126 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2128 * guile-snarf.in: Changed regexp to support CPPs that insert
2129 whitespace between lexical tokens (which munges the `%%%' snarf
2132 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2134 * load.c (scm_init_load_path): Append $(datadir)/guile to
2135 %load-path, so modules do not have to be installed in Guile's
2136 current version directory.
2138 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2140 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2141 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2142 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2143 call the sysdep functions with deferred ints.
2144 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2145 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2146 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2149 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2152 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2154 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2156 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2158 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2161 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2163 * eval.c (scm_lookupcar1): New procedure to cope with a race
2164 condition during lookup (when using threads).
2165 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2166 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2169 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2171 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2172 supplied. (Change from Tim Pierce.)
2174 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2176 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2177 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2178 default and not `()'. `#f' is the canonical non-value in Scheme,
2181 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2183 * struct.c (struct_printer): New variable that holds a handle on
2184 the Scheme variable *struct-printer*. This variable can be set by
2185 Scheme code to override the printing of structures.
2186 (scm_print_struct): If struct_printer is set, call it. If it is
2187 not set, or returns #f, print the structure in the old fashion.
2188 Include "eval.h" for scm_apply.
2190 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2192 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2193 scm_struct_i_n_words to get the number of fields, not
2194 -scm_struct_n_extra_words.
2196 On the route to fancier struct printing:
2197 * struct.c (scm_print_struct): New function to print a structure.
2198 Include "genio.h" to support it. This function doesn't do
2199 anything interesting right now, but I think it should be here
2201 * struct.h: Include "print.h" and add prototype for
2203 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2204 print structures ourself.
2206 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2208 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2209 before applying the handler in case it doesn't return.
2211 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2213 * scmsigs.h, async.h: updated.
2215 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2218 * posix.c (scm_uname): interpret only negative values as an error.
2219 Solaris normally returns a positive value.
2221 * script.c (scm_compile_shell_switches): if we are not going into
2222 an interactive repl, set scm_mask_ints to zero so that asyncs can
2225 * simpos.c (scm_system): don't ignore/unignore signals around
2228 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2231 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2232 done in boot-9.scm instead.
2234 * scmsigs.c, async.c: Major rewriting of signal handling code.
2235 (scm_sigaction): new procedure.
2236 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2238 (scm_raise): return unspecified, throw error on failure.
2240 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2242 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2243 feature, to help boot-9.scm decide whether to import the regex
2246 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2248 * eval.c: Include scmconfig.h at the beginning of the file so that
2249 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2252 * regex-posix.c: #include "_scm.h" before conditionally #including
2253 <regex.h>; the former defines HAVE_REGCOMP.
2255 * regex-posix.c: #include <regex.h> conditionally, so the file is
2256 CPP'able (for dependency scanning) even on systems that don't have
2259 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2261 Add new R4RS-compliant syntax for keywords.
2262 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2263 regardless of the setting of the `keywords' read option.
2264 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2265 can be re-read no matter what the setting of the `keywords' read
2268 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2270 Add support for POSIX regular expressions.
2272 * regex-posix.c, regex-posix.h: New files. (Some code
2273 is taken liberally from rx/rgx.c in the old Guile dist.)
2275 * init.c: Include regex-posix.h.
2276 (scm_boot_guile_1): Call scm_init_regex_posix.
2278 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2279 Add regex-posix.[ch] sources.
2280 * Makefile.in: Regenerated.
2282 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2283 to do this automatically? It didn't for me, bleh.)
2285 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2287 * fports.c (print_pipe_port): New function.
2288 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2289 latter doesn't even take the right arguments.
2291 * Makefile.am: Increment shared lib revision number. I think
2292 sometimes the uninstalled Guile finds the installed shared lib;
2293 Gord says doing this might help. As things turned out, I can't
2294 say whether it does.
2295 * Makefile.in: Regenerated.
2297 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2298 passing it as the closure argument to scm_boot_guile. (Bill
2301 * ports.c (print_void_port, putc_void_port, puts_void_port,
2302 write_void_port, flush_void_port, getc_void_port, close_void_port,
2303 noop0): Use ANSI prototypes instead of K&R declarations, so the
2304 initialization of void_port_ptob gets aggressively type-checked.
2305 Fix arguments of print_void_port and write_void_port. (Bill

2339 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2341 * script.c (scm_find_executable): Use prototype-style definition
2342 here; apparently it's not quite right to have const in a prototype
2343 and then use a K&R declaration. I wonder if stuff like this will
2344 go away if we compile with -Wrequire-prototypes, or whatever that
2345 is... (Bernard URBAN)
2347 * scmhob.h: New text from Bernard URBAN.
2349 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2351 * script.c: Don't #define const on hpux. Configure takes care of
2352 this. (Thanks to Larry Schwimmer.)
2354 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2355 decide whether to #include <unistd.h>, instead of listing a bunch
2356 of systems. Don't #include stdio twice. Removed dyked-out
2357 definition of scm_find_impl_file.
2359 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2361 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2362 library version info to 1:0.
2363 * Makefile.in: Regenerated.
2365 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

2369 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2370 throw.c: Update copyright years; these files have been worked on
2371 significantly in 1997, but only had copyright years for 1996.
2372 Also, change name of copyright holder on some from Mikael
2373 Djurfeldt to Free Software Foundation; he has signed papers
2374 assigning the changes to the FSF.
2376 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2377 reason not to give the user the option.
2379 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2380 Return #f on end-of-file when scanning table (i.e. when called
2381 with no arguments). Try to catch errors, when we can.
2382 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2384 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2385 external declarations. These are useful.
2387 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2389 * posix.c: don't include <sys/select.h> or define macros for
2390 select, since they were not used in this file.
2392 * filesys.c (scm_select): make the fifth parameter microseconds,
2393 not milliseconds. let the fourth parameter be either a real value
2394 or an integer or #f. The first, second and third arguments can
2395 now be vectors: the type of the corresponding return set will be
2397 (set_element, get_element): new static procedures.
2399 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2401 * strports.c (scm_eval_string): New function.
2402 (scm_eval_0str): Trivially re-implemented in terms of
2404 * strports.h (scm_eval_string): New extern decl.
2406 * net_db.c (h_errno): Add extern decl for this.
2408 * fports.c (local_pclose): New function.
2409 (scm_pipob): Use it in the initializer here.
2412 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2413 Use a meaningful error message when signalling an error. For
2414 this, scm_gethost must check h_errno rather than errno.
2416 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2418 * Makefile.in: Regenerated, using automake-1.1p.
2420 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2422 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2423 not SCM_UNSPECIFIED.
2425 * script.c (scm_compile_shell_switches): don't append (quit) if
2427 (scm_shell): call scm_exit_status and exit on the result of the
2430 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2432 Ensure that shared substrings are handled properly when passed to
2433 a system call or other foreign function. Many thanks to Tim
2435 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2436 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2437 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2438 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

2445 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
2446 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
2447 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
2448 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
2449 scm_strftime), vports.c (scm_make_soft_port): use
2450 SCM_COERCE_SUBSTR to make sure shared substrings are

2455 * error.c (scm_error): Add newline to error message.
2457 * init.c (scm_init_standard_ports): Doc fix.
2459 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2461 * dynl-shl.c: Completely replaced with new code from Bernard
2464 * script.c (scm_ice_9_already_loaded): New variable.
2465 (scm_compile_shell_switches): Use it.
2467 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2469 * filesys.c (scm_input_waiting_p): add missing third argument to
2472 * stime.c (scm_localtime): copy the result of localtime before
2473 calling gmtime in case they share a buffer.
2474 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2477 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2479 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2481 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2483 * Makefile.am (check-local): New target, which causes 'make check'
2484 to run gh_test_c and gh_test_repl, with some trivial input.
2485 * Makefile.in: Rgnrtd.
2487 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2489 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2492 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2494 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2495 sure how this was supposed to work.
2496 (scm_async_click): don't send SCM_TICK_SIGNAL.
2497 (scm_init_async): don't initialize %tick-thunk.
2499 * the following change doesn't affect the Scheme interface:
2500 gc-thunk is called at the end of garbage collection. however it's
2501 no longer implemented by pretending it's a signal.
2503 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2504 system async corresponding to scm_gc_thunk.
2505 * async.h: declare scm_gc_async.
2506 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2507 gc-thunk directly, instead of going through a signal handler.
2508 (scm_gc_async): new variable, points to the GC system-async.
2509 (scm_init_async): save the GC async as scm_gc_async instead
2510 of using system_signal_asyncs.
2511 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2513 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2515 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2516 Don't screw up if we're interrupted.
2517 * Makefile.in: Regeneradet.
2519 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2521 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2523 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2524 we're not using AM_INIT_GUILE_MODULE any more.
2525 * Makefile.in: Reneregated.
2527 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2529 Functions for finding variable bindings, grace à Tim Pierce.
2530 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2531 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2533 Get 'make dist' to work again.
2534 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2535 * Makefile.in: Regenerated, like a surry without a fringe on top.
2537 Changes for reduced Guile distribution: one configure script,
2539 * configure.in, configure: Removed.
2540 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2541 real configure script lives.
2542 * Makefile.in, scmconfig.h.in: Regenerated.
2544 * init.c: #include "script.h", to get prototype for script.c's
2547 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2549 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2550 scm_must_malloc, not raw malloc.
2552 * script.c (scm_compile_shell_switches): Dyke out debugging output
2555 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2557 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2559 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2560 system has them. Hope this is safe. Previously
2561 sys/timeb.h was included if HAVE_FTIME was defined or if
2562 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2563 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2565 * ioext.c (scm_setfileno): add missing third argument to
2566 scm_misc_error call.
2568 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2570 * eq.c (scm_equal_p): Correctly compare strings of different
2571 varieties. (Thanks to Tim Pierce.)
2573 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2575 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2576 #! block comment must occur on a line all by itself.
2578 Move most of the guts of shell command processing into libguile,
2579 so guile.c can be very small (and eventuallly auto-generated. (I
2580 mean, generated mechanically, not self-generated. Hmm.))
2581 * guile.c, script.c, script.h: New source files.
2582 * init.c (scm_boot_guile_1): Call scm_init_script.
2583 * libguile.h: #include "script.h".
2584 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2585 targets, for new executable.
2586 (libguile_la_SOURCES): Mention script.c.
2587 (modinclude_HEADERS): Add script.h.
2588 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2589 not dynamic linking is enabled. This is because we're generating
2590 executables now. Move CY_AC_WITH_THREADS call after those, so the
2591 values of cy_cv_threads_libs captures the libs chosen above.
2592 * Makefile.in, configure, aclocal.m4: Regenerated.
2594 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2595 We don't maintain this interface any more, and it just confuses
2598 * alloca.c: #include <scmconfig.h>, not <config.h>.
2599 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2600 it'll get included in disties.
2602 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2604 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2605 be distributed, because they confuse people.
2606 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2608 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2610 * configure.in: check for presence of gethostent (not present on
2611 OpenBSD by default).
2612 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2613 * configure, scmconfig.h.in: Regenerated.
2615 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2617 * backtrace.c (scm_backtrace): Split message string across
2618 newlines properly. GCC is more tolerant of this than other
2621 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
2623 Merge threads directory into libguile.
2624 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
2625 threads.h: New source files.
2626 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
2627 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2629 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2630 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2631 coop-threads.c.cygnus, coop-threads.h.cygnus.
2632 * configure.in: If we're using threads, include threads.o in
2634 * _scm.h, libguile.h: threads.h lives in this directory now.
2635 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2636 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2637 currently used, but brought along for information's sake.
2638 * ChangeLog-threads: log from old 'threads' directory.
2639 * Makefile.in, configure: Rebuilt.
2641 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2643 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2646 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2648 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2650 Merge GH interface library into libguile.
2651 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
2652 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2653 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2654 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2656 (EXTRA_libguile_la_SOURCES): ... here.
2657 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2658 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2659 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2660 New variables, describing how to build the gh test programs.
2661 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2662 build the test programs, and we probably should have been linking
2663 libguile.la against them all along, to support AIX shared libs.
2664 Add cflags for threads to CFLAGS; add libs for threads to new
2665 variable THREAD_LIBS, used in Makefile.am.
2666 * ChangeLog-gh: log from old `gh' subdirectory.
2667 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2669 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2671 * acconfig.h: Undo change of Apr 9; including the definition of
2672 PACKAGE in the guile headers conflicts with applications' own
2674 * scmconfig.h.in: Regenerated.
2676 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

2680 * filesys.h: Added prototype.
2682 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
2683 when PROC is receiving no arguments.
2685 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2687 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2688 have S_IFSOCK. This is the case under Ultrix.
2690 * posix.c (scm_status_exit_val, scm_status_exit_val,
2691 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2692 Ultrix versions of WIFSTOPPED, etc., which assume that their
2693 arguments are lvalues (hmm).
2695 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2697 * eval.c: Doc fixes.
2699 * throw.c: Doc fixes; rearranged.
2701 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
2703 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
2705 * acconfig.h: Added entry for PACKAGE.
2706 * scmconfig.h.in: Regenerated.
2708 Changes to work with automake-1.1n, which has better libtool support.
2709 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2710 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
2712 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
2714 * Makefile.in: Rebuild.
2716 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2718 * stime.c (scm_mktime): take an optional zone argument.
2719 (scm_localtime): check putenv return value.
2720 (scm_strftime, scm_strptime): moved from posix.c. move #include
2722 stime.h, posix.h: update prototypes.
2723 (bdtime2c, setzone, restorezone): new static procedures.
2724 (scm_mktime, scm_strftime): use them.
2725 (scm_strftime): don't call mktime before strftime. Use
2726 filltime for return value.
2727 (filltime): convert NULL zname to #f.
2728 (scm_strptime): return a count of characters consumed, not
2729 the remaining string.
2731 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2733 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
2734 (scm_mktime): likewise.
2736 Uncomment localtime and mktime.
2738 * configure.in: add AC_STRUCT_TIMEZONE.
2740 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2742 * stime.c (scm_init_stime): don't define ticks/sec.
2743 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2744 return value problem and is still portable.)
2746 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2748 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2749 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2750 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2751 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2752 cpp_err_symbols.c): Corresponding changes.
2753 * Makefile.in: Regenerated.
2755 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2757 * posix.c (scm_putenv): don't check HAVE_PUTENV.
2758 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
2759 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
2760 * putenv.c: new file, from sh-utils 1.12.
2762 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2763 since allocation isn't for Scheme objects.
2764 (scm_putenv): copy strings before placing in the environment.
2766 * stime.c (scm_current_time): throw an error if time returns -1,
2767 instead of returning #f.
2768 (scm_get_internal_real_time, scm_get_internal_real_time): use
2769 scm_long2num for return value instead of SCM_MAKINUM.
2771 * stime.h: prototypes updated.
2773 * stime.c (scm_time_in_msec): apparently unused, deleted.
2775 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2777 * configure.in: check for gettimeofday.
2779 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2780 which may be more usefully portable than a gettimeofday interface.
2782 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2784 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
2786 * Makefile.in: Regenerated.
2788 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2790 * stime.c (filltime): recovered static procedure.
2791 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
2794 * posix.h: add prototype for scm_close_pipe, remove prototypes for
2795 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2797 * posix.c (scm_mknod): split the mode argument into type and perms
2798 arguments, like the extra fields returned by stat.
2800 * fports.c (scm_pipob): set the close, free and print procedures.
2801 (scm_close_pipe): new procedure.
2803 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2804 define them in boot-9.scm
2806 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2808 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
2809 wan't defined. Don't include fd.h.
2811 * Previously fd.h was regenerated whenever configure was run,
2812 forcing a couple of files to be recompiled.
2814 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
2815 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
2816 Check for _fileno as well as _file.
2818 * ioext.c: don't fd.h.
2819 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
2822 * Change the stratigy for getting information about errno
2823 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
2824 generating lists of symbols during the build process, which will
2825 not always work, include comprehensive lists in the distribution.
2826 To help keep the lists up to date, the "check_signals" and
2827 "check_errnos" make targets can be used.
2829 * configure.in: don't check for a command to extract errno codes.
2830 * Makefile.am: update file lists, remove errnos.list and errnos.c
2831 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
2832 check_errnos targets.
2833 (CLEANFILES): remove errnos.c and errnos.list, add
2834 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
2835 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
2836 * errnos.default: deleted.
2837 * cpp_signal.c: new file.
2838 * cpp_errno.c: renamed from errnos_get.c.
2839 * cpp_err_symbols, cpp_sig_symbols: new files.
2840 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
2841 * error.c (scm_init_error): #include cpp_err_symbols instead of
2843 * posix.c (scm_init_posix): don't intern signal symbols. #include
2846 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
2848 * strop.c (scm_i_index): allow the lower bound to be equal to the
2849 length of the string, so a null string doesn't always give an error.
2851 * posix.h: new prototypes.
2852 * posix.c (scm_status_exit_val, scm_status_term_sig,
2853 scm_status_stop_sig): new functions, as in scsh. They break down
2854 process status values as returned by waitpid.
2856 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
2858 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
2859 configure doesn't know about it.
2861 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2863 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
2865 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
2866 which defines C variables with global linkage.
2868 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2870 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
2873 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
2875 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
2876 has time to check why this doesn't work well with continuations.
2878 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
2880 * Fix shell syntax error; some shells won't tolerate
2881 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
2883 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2885 * posix.c (scm_uname): throw an error if uname fails instead
2888 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
2890 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
2893 * async.c (scm_ints_disabled): definition moved from error.c.
2895 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2897 * acconfig.h: Removed PACKAGE.
2899 * scmconfig.h.in: Regenerated.
2901 * snarf.h: g++ says it's non-portable not to specify the first
2902 argument in a varargs declaration. I introduced the first
2903 argument by using preprocessor conditionals.
2905 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
2907 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
2908 (scm_freopen): use RO string macros for filename and modes.
2909 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
2911 * posix.c (scm_getgrgid): simplify conversion of name to C string.
2912 (scm_mknod): use RO string macros for path.
2914 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
2915 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
2917 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2918 use SCM_ROSTRINGP and SCM_ROCHARS.
2920 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2922 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
2925 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
2926 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
2927 support for byte vectors.
2929 * print.c (scm_iprin1): Limit number of vector elements printed
2930 according to pstate->length.
2932 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2934 * backtrace.c (scm_display_error_message): don't segv if message
2937 * error.h: prototype for scm_error_scm.
2939 * error.c (scm_error_scm): new procedure, reimplements scm-error
2940 in C and uses scm_error.
2942 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2944 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
2945 pointer to the Scheme variable read-hash-procedures and intern it
2946 in scm_init_read. Modify scm_read_hash_extend and
2947 scm_get_hash_procedure to use the pointer.
2949 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2951 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
2952 (SCM_KEYWORD_STYLE): defined.
2954 * read.c (scm_read_opts): add a keywords option. This isn't a
2955 boolean option, in case someone wants to add support for DSSSL
2957 Setup scm_keyword_prefix symbol.
2958 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
2960 I've left keyword support disabled by default, since it doesn't
2961 seem to break the module system and it gives R4RS standard behaviour.
2962 It can be reactivated with (read-set! keywords 'prefix).
2964 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2966 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
2967 before constructing arbiter.
2969 * eval.c (scm_m_define): Bugfix: Check that the object is a
2970 closure before setting the procedure property!
2972 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
2974 * ports.c: Removed `ungetc-char-ready?'.
2976 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
2978 * read.c (scm_init_read): intitialise scm_read_hash_procedures
2979 (idea from Mikael: make it a pair so scm_permanent object only
2981 (scm_read_hash_extend): don't call scm_permanent_object.
2982 (ideas from Mikael): if chr is already in the list, replace its
2983 procedure instead of appending it again. If proc is #f, remove
2985 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
2987 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
2989 * gdbint.c (gdb_read): update scm_lreadr usage.
2991 * load.h: update prototypes.
2993 * load.c (scm_primitive_load, scm_read_and_eval_x,
2994 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
2996 * read.h: add prototype for scm_read_hash_extend. Change args for
2999 * read.c (scm_read_hash_procedures): new variable.
3000 (scm_read_hash_extend): new procedure.
3001 (scm_get_hash_procedure): new procedure.
3002 (scm_lreadr): use scm_get_hash_procedure instead of an argument
3003 for extended # processing.
3004 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
3005 scm_read_token): remove case_i, sharp arguments. Change callers.
3007 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
3009 * read.h (SCM_N_READ_OPTIONS): increase to 3.
3010 (SCM_CASE_INSENSITIVE_P): define.
3012 * read.c: add case-insensitive option to scm_read_opts.
3013 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
3014 to determine whether to convert symbol case.
3015 (default_case_i): definition removed.
3016 * read.c (scm_read_token): if case_i, downcase ic before doing
3019 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3021 * configure.in: Added configuration option `guile-debug'.
3022 Configure with --enable-guile-debug if you want a bunch of extra
3023 functions used for debugging when developing Guile.
3025 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3027 * procs.c (make-cclo): New undocumented debugging procedure: Make
3028 compiled closure with internal procedure PROC and length LENGTH.
3029 Only compiled if GUILE_DEBUG is defined.
3031 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3033 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3035 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3037 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3038 with 3 or more args internally to the evaluator.
3040 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3042 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3043 with 3 or more args internally to the evaluator. This is mainly
3044 because we don't want to pass entry and exit points of the
3045 debug support twice, but it also seems to increase the speed of
3046 the evaluator for such calls (e. g. (+ 1 2 3)).
3048 * backtrace.c (scm_display_application): New procedure:
3049 display-application; Set fancy printing parameters individually
3050 for different types of display (backtrace, error, application).
3051 (These should of course be customizable!)
3053 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3054 clear the CHECK-flags.
3056 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3058 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3060 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3062 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3063 from pairs with a GLOC in the car.
3065 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3066 otherwise `symbol-hash' will behave badly.
3067 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3068 we get segmentation fault!
3070 * symbols.c: Added #include "weaks.h". New functions:
3071 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3072 moved to an extraneous library when we split libguile.)
3074 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3076 * filesys.c (scm_stat): stat now takes fport arguments too as
3077 documented in the manual.
3079 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3081 * debug.c (scm_single_step): Bugfix: Call continuation with
3082 scm_call_continuation instead of throwing to it.
3084 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3086 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3087 argument wasn't declared to be optional.
3089 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3091 * stime.c (scm_init_stime): Add feature "current-time".
3093 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3095 * throw.h: prototype for scm_exit_status.
3096 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3097 args to derive an exit status. Allows (quit) to work from a
3099 (scm_exit_status): new function.
3102 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3104 * eval.c (scm_deval): Removed some old code.
3105 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3107 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3110 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3113 * procs.c: Introduce the existent C function scm_thunk_p at the
3114 Scheme level as well.
3116 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3118 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3119 used from C to easily lookup the value of a symbol in the current
3122 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3124 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3125 scm_init_unif in this file. This will also fix a previous problem
3128 * configure.in: Added AM_MAINTAINER_MODE
3130 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3132 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3135 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3137 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3138 source files that are not always included in libguile but should
3139 have their dependencies calculated by automake. This variable is
3140 recognized by automake, no further magic is needed.
3141 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3142 to deal exclusively with *.lo files, as it seems. The *.o files
3143 are built automatically when the corresponding *.lo file gets
3146 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3148 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3151 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3153 * unif.c (scm_array_set_x): minor change to argument error checking.
3155 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3157 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3158 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3159 They should only be included in the library at configure.in's
3161 (libguile_la_LDADD): Include the appropriate .lo files here.
3162 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3163 so we know when to build them (and their .lo bretheren).
3164 * configure.in (LIBLOBJS): New substituted variable. We let
3165 configure decide which .o files to include in LIBOBJS, and then
3166 put the corresponding list of .lo files in LIBLOBJS. The latter
3167 is what we pass to libtool.
3168 * Makefile.in, configure: regenerated.
3170 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3172 * symbols.c (scm_sysintern0): New function. Contains the core of
3173 old scm_sysintern but doesn't take a second value argument.
3174 (scm_sysintern): Now uses scm_sysintern0.
3175 (scm_sysintern_no_module_lookup): Renamed to
3176 scm_sysintern0_no_module_lookup and doesn't take a second value
3177 argument any longer.
3179 * symbols.h (scm_sysintern0: Added declaration.
3181 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3182 scm_sysintern when interning option keys. Otherwise we risk
3183 destroying the values of already interned variables.
3185 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3186 scheme-level boolean (use SCM_NFALSEP).
3188 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3190 (scm_backtrace): New function. (C version of old function from
3191 boot-9.scm) Motivation: Make it possible to display backtraces
3192 without depending on boot-9.scm. (I'm uncertain if this
3193 motivation is good enough...)
3195 * root.h (scm_root_state): Add member the_last_stack_var.
3196 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3198 * root.c (mark_root): Mark scm_the_last_stack_var.
3200 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3203 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3205 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3206 1. mark_lazy_catch didn't mark the smob.
3207 2. Both functions above have standard variants:
3208 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3209 free_lazy_catch --> scm_free0.
3211 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3213 * throw.c (scm_internal_lazy_catch): New function.
3214 (scm_lazy_catch): Rewritten to use it.
3215 (scm_ithrow): Handle the new lazy catch representation.
3216 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3217 that doesn't have a jmpbuf is a lazy catch clause.
3218 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3219 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3220 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3222 (scm_init_throw): Register the new lazy-catch smob type.
3223 * throw.h (scm_internal_lazy_catch): decl for new function.
3225 * throw.c (scm_internal_catch): Doc fixes.
3227 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3228 configure.in. Including this might cause problems if applications
3229 that link against libguile include their own copies of alloca, but
3230 if they're using autoconf, they should be adding libguile to LIBS
3231 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3232 the copy in libguile, and things will be okay. (I think.)
3234 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3236 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3238 strop.h: move prototypes too.
3240 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3242 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3245 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3246 etc. I deleted them from filesys.c long ago, but didn't
3247 notice they were here too (although ineffective since
3248 sys/stat.h wasn't included).
3250 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3252 * eval.c: Don't define alloca in GCC case. gcc will automatically
3253 use __builtin_alloca if appropriate.
3255 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3257 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3258 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3259 that values of automatic variables are preserved. See comments
3260 for safe_setjmp for details.
3262 Change from Thomas Morgan:
3263 * variable.c: Include eq.h.
3264 (var_equal): New function.
3265 (variable_smob): Use var_equal as the discriminator for variables.
3267 * throw.c (s_throw): Remove extraneous declaration.
3269 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3270 * eval.c: Add necessary CPP cruft to support that.
3271 * configure, Makefile.in, scmconfig.h.in: regenerated.
3273 Change from Thomas Morgan:
3274 * procprop.c (scm_procedure_properties): Convert the Scheme
3275 boolean returned by scm_procedure_p into a C boolean before using
3276 it as a condition for SCM_ASSERT.
3277 (scm_procedure_property): Likewise.
3279 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3280 indications of Unixness.
3283 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3285 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3287 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3289 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3290 "unknown # object" error messages.
3292 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3293 (scm_i_index) and declare it static. Add a 'direction' argument
3294 to indicate what way the search should go.
3295 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3297 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3298 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3300 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3302 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3304 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3305 to avoid clash with various scsh forks.
3307 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3309 The following two changes (ramap.c, throw.c) are motivated by the
3310 apparent unportability of forward declarations of static arrays of
3311 the form `static foo bar[];'.
3313 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3314 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3316 * throw.c (scm_throw): Moved above scm_ithrow.
3318 * options.h: Removed the extern declarations of scm_yes_sym and
3319 scm_no_sym since these are static.
3321 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3323 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3325 * Makefile.am: remove AWK=@AWK@.
3326 Add a rule for generating errnos.list.
3327 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3329 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3330 don't extract errnos, just set a variable (avoids the
3331 need to recompile error.c just because configure is run.)
3333 * unif.h: update prototypes.
3334 * unif.c (scm_uniform_array_read,write): change the offset and
3335 length arguments to start and end, for consistency.
3337 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3339 * ioext.h: update prototypes.
3340 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3341 scm_read_line_x, it's a more general procedure using an
3342 interface from scsh. read-line and read-line! are now defined
3344 Note that the new read-line trims the terminator
3345 by default, previously it was appended to the returned string. An
3346 optional argument specifies how to process the terminator (scsh
3347 compatible). For the old behaviour: (read-line port 'concat).
3348 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3349 returns a pair, but is converted to multiple values if the scsh
3352 socket.h: update prototypes.
3353 * socket.c (scm_recvfrom): for consistency with other procedures,
3354 take start and end as separate optional arguments.
3355 (scm_recv, scm_recvfrom): don't allow the second argument
3356 to be a size, only a buffer. Change the scheme names to
3357 recv! and recvfrom!. Don't return the buffer.
3359 * ioext.h, posix.h: move prototypes too.
3360 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3361 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3362 "read.h" and "unif.h".
3363 * ioext.c: include "chars.h"
3365 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3367 * dynl.c: The dynamic linking and module registration functions
3368 are now defined even when dynamic linking is not available for the
3369 host system. Some of their functionality can be done without
3370 dynamic linking; when it's really needed, they throw errors.
3372 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3374 * configure.in: Only define DYNAMIC_LINKING when one of the system
3375 dependent functions is detected.
3376 * dynl.c (scm_dynamic_func): New function to get the address of a
3377 function in a dynamic object.
3378 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3379 produced by scm_dynamic_func as the thing to call.
3381 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3383 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3384 (scm_register_module_xxx, scm_registered_modules,
3385 scm_clear_registered_modules): New functions.
3387 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3389 * symbols.c (scm_sysintern): Renamed to
3390 scm_sysintern_no_module_lookup.
3391 (scm_sysintern): New function to take the place of the old
3392 scm_sysintern. It uses the current toplevel lookup closure to give
3393 the symbol its value. This is a temporary hack to put packages
3394 like gtcltk into their own module.
3395 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3396 us whether `scm_top_level_lookup_closure_var' has been initialized
3398 * eval.c (scm_init_eval): Set it.
3400 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3402 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3403 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3405 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3407 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3408 scm_sys_dup): deleted: FD capability will be added to other
3410 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3411 scm_fd_free, fd_smob, scm_intern_fd.
3412 (scm_open): renamed from scm_sys_open. Return a port instead of
3413 an FD object. Make the mode argument optional.
3414 (scm_sys_create): deleted, it's just a special case of open.
3415 (scm_init_filesys): move interning of constants O_CREAT etc.,
3416 here (were previously using SCM_CONST_LONG macro).
3417 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3419 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3420 include "fports.h" and <stdio.h>
3421 (scm_stat, scm_select): don't support FD objects.
3423 * error.h: adjust scm_syserror_msg prototype.
3424 * error.c (scm_syserror_msg): take an extra argument for errno.
3425 Using the global value didn't always work, since it could be
3426 reset by procedure calls in the message or args arguments.
3428 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3429 I don't understand why the check was there (and what about the
3432 * strop.c (scm_string_copy): allow shared substrings to be copied.
3434 * unif.h: corresponding change to prototypes.
3435 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3436 recognize two new optional arguments: offset and length. Allow
3437 the port argument to be an integer (file descriptor, for scsh).
3438 Include <unistd.h> for "read" prototype.
3440 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3442 * socket.c: don't include filesys.h.
3444 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3446 * Makefile.am: add AWK=@AWK@ (?)
3448 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3450 Add a rule to generate errnos.c from errnos.
3451 * error.c (scm_init_error): include errnos.c.
3452 * errnos_cnvt.awk: new file, converts the list of errno codes to
3454 * errnos_get.c: new file.
3455 * errnos.default: new file, contains errnos to try if they can't
3456 be extracted from errno.h.
3457 * configure.in: if using GCC, try and extract errno codes from
3461 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3463 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3464 * Makefile.am: Made libguile into a libtool library.
3465 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3466 Set libtool_libs to indicate that libguile is a libtool library.
3467 See guile/ChangeLog for details.
3468 * .cvsignore: ignore "*.lo", the libtool library objects.
3470 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3472 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3473 use htons in getservbyport argument.
3475 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3477 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3478 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3481 * objprop.c (scm_object_property): No need to take the CDR of the
3482 value returned by scm_object_properties, since Aug 20 change.
3484 * configure.in: When checking for struct linger, #include
3485 <sys/types.h> as well as <sys/socket.h>. I've never known
3486 <sys/types.h> to cause any portability problems, and Solaris's
3487 <sys/socket.h> needs it.
3488 * configure: Rebuilt.
3490 I think the Sun compiler has chosen a perverse way to interpret
3491 ANSI declarations combined with K&R definitions. We'll
3492 appease it a little bit. But when it invades France, we fight.
3493 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3494 * print.h (scm_iprlist): Here too.
3495 * numbers.c (scm_divbigdig): Change definition to match
3496 declaration in numbers.h.
3497 * unif.c (scm_makflo): Change definition to match declaration in
3500 * init.c (scm_boot_guile): Don't return the value of
3501 scm_boot_guile_1. This function doesn't return a value;
3502 scm_boot_guile_1 doesn't return a value (or return at all).
3504 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3507 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3508 compile. I have a feeling this function is a bad idea anyway ---
3509 one should always test for features, not systems.
3511 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3512 semicolons. Only pure luck kept this from being noticed earlier.
3514 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3516 * socket.c (scm_recvfrom): Added missing semicolon.
3518 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3520 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3521 the buffer and start and end positions for scsh networking
3524 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3526 * configure.in: Revert previous change to this file; the problem
3527 is due to transient automake weirdness.
3528 * configure: Rebuilt.
3530 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3531 PLUGIN/guile.libs. configure generates the latter from the former.
3532 * Makefile.in: Rebuilt.
3534 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3535 need this if we install scripts, like guile-snarf.
3536 * configure: Rebuilt.
3538 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3540 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3542 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3544 * socket.c (scm_addr_vector): fix faulty scm_listify.
3546 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3548 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3549 style block comment is no longer considered an error.
3551 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3553 * PLUGIN/guile.libs.in: New file.
3554 * PLUGIN/guile.libs: Removed from repository.
3555 * configure.in: Create PLUGIN/guile.libs from
3556 PLUGIN/guile.libs.in. This is for including additonal libraries
3557 needed for dynamic linking.
3558 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3559 instead of PLUGIN/guile.libs.
3561 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3563 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3565 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3566 occurrences of the given element from the list, not just the
3567 first. This is how the Emacs Lisp functions behave, how the
3568 analogous Common Lisp functions behave, and (I believe) how the
3569 older Maclisp functions worked. I realize that this change may
3570 break code, but it seemed better to break it before the Guile
3573 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3574 Their prototypes were already present in gc.h, but they weren't
3576 (scm_init_storage): Initialize scm_protects.
3577 * root.c (scm_protects): New element of scm_sys_protects.
3579 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3581 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3583 * libguile.h: Added #include "libguile/net_db.h".
3585 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3586 30 change. That file is only meant for communication between the
3587 configuration process and load.c. If code linked against libguile
3588 wants to get at the paths mentioned in libpath.h, it can call
3589 functions declared in load.h.
3591 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3593 * libguile.h: Removed #include "libguile/fdsocket.h"
3595 * net_db.c: Added #include <sys/socket.h>.
3597 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3599 * filesys.c (scm_input_waiting_p): use select in preference to
3600 FIONREAD, since the latter doesn't detect EOF.
3601 Throw error if neither select nor FIONREAD available.
3603 * socket.c (scm_connect): take a port, not a fd object.
3604 (scm_fill_sockaddr): throw an error if fam is not recognised.
3605 (scm_bind): use scm_fill_sockaddr.
3606 (scm_listen): take a port, not a fd object.
3607 (scm_accept): take and return a port. return #f in the car if
3608 address can't be got
3609 (scm_sock_fd_to_port): new procedure.
3610 (scm_socket): use scm_sock_fd_to_port.
3611 (scm_addr_vector): throw error if unrecognised address type.
3612 take an extra argument with the calling procedure name.
3613 (scm_getsockname): take a port. return #f if address can't be got.
3614 (scm_getpeername): take a port. return #f if address can't be got.
3615 (scm_recvfrom): take a port. return #f for address component if can't
3617 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3618 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3620 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3622 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3623 use separate data pointers, to allow them to be designed
3624 independently and reused.
3625 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3626 Renamed from catch_body, catch_handler, and uncaught_throw; made
3628 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3630 (scm_catch): Use the above.
3631 (scm_throw): Don't bother printing a message for an uncaught
3632 throw; we establish a default handler in init.
3633 * throw.h (scm_internal_catch): Prototype updated.
3634 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3636 (struct scm_body_thunk_data): New structure, used as data
3637 argument to scm_body_thunk.
3638 * init.c (struct main_func_closure): New structure, packaging up
3639 the data to pass to the user's main function.
3640 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3641 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3642 scm_internal_catch to establish a catch-all handler, using
3643 scm_handle_by_message. This replaces the special-case code in
3645 (invoke_main_func): Body function for scm_internal_catch; invoke
3646 the user's main function, using the main_func_closure pointer to
3647 decide what to pass it.
3648 * root.c (struct cwdr_body_data): Remove handler_proc member.
3649 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3650 (cwdr_handler): Removed.
3652 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3654 * socket.h (SCM_P): update bind prototype.
3655 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3656 include "feature.h".
3657 (scm_socket): return a port, not a file descriptor object.
3658 include "fports.h" and <unistd.h>
3659 (scm_bind): take a port, not a file descriptor object.
3660 take an extra argument for address args.
3662 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3663 INADDR_NONE, INADDR_LOOPBACK.
3665 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3667 * init.c: include net_db.h and not fdsocket.h.
3668 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3670 * Makefile.am: corresponding changes.
3671 * socket.h: renamed from fdsocket.h, fix names.
3672 * net_db.h: renamed from socket.h, fix names.
3673 * socket.c: renamed from fdsocket.c.
3674 remove _sys from procedure names.
3675 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3676 add "socket" to features list.
3677 * net_db.c: renamed from socket.c.
3678 remove _sys from procedure names.
3679 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3680 add "net-db" to features list.
3681 include "net_db.h". don't include <sys/socket.h> or
3684 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3686 * tags.h (scm_tags): Removed comma at end of last enumerator.
3688 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3690 Don't use GCC extensions to allocate space for debugging frames.
3691 (Here he goes again! Why do we put up with this?!)
3692 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3693 an scm_debug_info structure, not an in-line array of them. Add
3694 'info' member, to say how many vect elements we've used, for eval
3696 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3697 a new variable debug_info_end to mark the end of vect, instead of
3698 the address of the 'info' pointer itself.
3699 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3700 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3701 (SCM_APPLY): Explicitly allocate space for debug.vect.
3702 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3703 * stacks.c: Adjusted for new debug frame structure.
3704 (RELOC_INFO, RELOC_FRAME): New macros.
3705 (stack_depth, read_frames): Use them, and new scm_debug_frame
3706 element 'info', instead of magically knowing that eval frames have
3707 an info pointer sitting after vect.
3708 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3710 (scm_init_stacks): Formatting tweaks.
3712 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3714 Give GCC more control flow information, so it can be sure that
3715 variables aren't used uninitialized.
3716 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3717 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3718 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3719 scm_misc_error): Tell GCC that these functions never return.
3720 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3721 out the field type, call abort if SCM_ASSERT returns, to placate
3723 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3724 scm_wta ever returns. We can't handle this case anyway, and this
3725 gives the optimizer more information.
3726 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3727 scm_wta ever returns.
3729 In some cases, the code is fine, but GCC isn't smart enough to
3730 figure that out; this usually happens when one variable is only
3731 initialized and used when a particular condition holds true, and
3732 we know that condition will never change within a given invocation
3733 of the function. In this case, we simply initialize the variables
3734 to placate the compiler, hopefully to a value which will cause a
3735 crash if it is ever actually used.
3736 * print.c (scm_iprin1): Initialize mw_pos.
3737 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3738 * throw.c (scm_ithrow): Initialize dynpair.
3739 * unif.c (scm_uniform_vector_ref): Initialize cra.
3740 * struct.c (init_struct): Initialize prot.
3741 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3743 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3744 if EXPR contains no expressions.
3746 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3748 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3749 cause an infinite loop (???). So much for the algebraic
3750 equivalency of variable-sized arrays and alloca...
3752 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3754 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3755 a SCM boolean, not a C boolean.
3757 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3759 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3760 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3761 rules for raising scm_mtrigger. Previously, unfortunate but not
3762 unlikely circumstances could result in almost constant invokation
3763 of the gc. Now, this situations should be less likely, but they
3764 are not prevented completely.
3766 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3768 * numbers.c (scm_fuck): Procedure removed; looks like old test
3770 * numbers.h: Prototype removed.
3772 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3774 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3775 array to a pointer, to match my Nov 21 change in eval.c.
3777 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3779 * libguile.h: Added #include "libguile/backtrace.h", #include
3780 "libguile/stacks.h".
3782 * strings.c (scm_string scm_make_string scm_string_ref
3783 scm_string_set_x scm_string_equal_p scm_string_append):
3784 Bugfix according to scm patch from Aubrey Jaffer:
3785 Corrected long-standing
3786 (not (eqv? (integer->char 128)
3787 (string-ref (make-string 1 (integer->char 128)) 0)))
3788 bug found by John Kozak <jk@noontide.demon.co.uk>.
3790 * strports.c, strports.h: Make scm_eval_0str return the value of
3791 the last expression evaluated (previously, it returned void).
3793 * strports.c, strports.h: New function: scm_read_0str. Does what
3796 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3798 * simpos.c (scm_getenv): return #f if string can't be found in the
3799 environment instead of throwing an exception, for compatibility
3800 with numerous other systems.
3802 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3804 * Makefile.am (.c.x): Use guile-snarf.
3805 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
3807 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
3809 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3811 * backtrace.c (scm_display_error_message): Made non-static, and
3812 renamed from display_error_message.
3813 * backtrace.h (scm_display_error_message): Added extern decl.
3814 * throw.c (uncaught_throw): Use it to display the error message.
3816 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
3818 * inet_aton.c: Use #if 0, not #ifdef 0.
3820 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
3822 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
3823 to convert the returned value.
3824 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
3825 the offset argument.
3827 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3829 Add new interface to catch/throw, usable from C as well as
3831 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
3832 (scm_internal_catch): New function, replaces...
3833 (scm_catch_apply): Deleted.
3834 * throw.c (scm_catch_apply): Deleted; replaced with a more general
3835 mechanism which is a bit more code, but can be used nicely from C
3836 and implement the Scheme semantics as well.
3837 (scm_internal_catch): This is the replacement; it's named after
3838 the analogous function in Emacs.
3839 (scm_catch): Reimplemented in terms of the above.
3840 (struct catch_body_data, catch_body, catch_handler): New
3841 functions, used by scm_catch.
3842 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
3843 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
3844 support for new cwdr.
3846 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
3849 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
3851 * acconfig.h: Added DYNAMIC_LINKING symbol.
3852 * configure.in: Add option and checks for dynamic linking.
3853 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
3854 dynl.h: New files for dynamic linking support.
3855 * Makefile.am (libguile_a_SOURCES):
3857 (modinclude_HEADERS): Added "dynl.h".
3858 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
3860 * init.c (scm_boot_guile_1): Call
3861 scm_init_dynamic_linking to initialize dynamic linking support.
3863 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
3865 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
3866 (as we Schemers say). It needs to be global, so that I can tweak
3867 it for the proper operation of unexec.
3868 (scm_boot_guile_1_live): New variable, see above.
3870 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
3872 * guile-snarf.sh: Removed.
3873 * PLUGIN/guile.libs: Added dependency for -lm.
3874 * acinclude.m4: Renamed from aclocal.m4.
3875 * PLUGIN/greet: Removed.
3876 * Makefile.am, aclocal.m4: New files.
3877 * configure.in: Updated for Automake.
3879 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
3881 * eval.c (scm_definedp): Use top_level_lookup_closure_var
3882 and not top_level_lookup_thunk_var.
3884 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
3886 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
3888 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
3890 * eval.c (scm_definedp): Incompatibly changed to be a builtin
3891 Scheme function, instead of syntax. Single argument is now a
3894 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3896 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
3897 scm_ra_divide): Properly terminate statements passed as arguments
3898 to IVDEP macros. (Thanks to Bernard Urban.)
3900 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
3901 with non-constant sizes. (Thanks to Bernard Urban.)
3903 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3905 It's an "eval closure", not an "eval thunk." A thunk is a
3906 function of no arguments.
3907 * root.h (struct scm_root_state): Renamed
3908 top_level_lookup_closure_var from top_level_lookup_thunk_var.
3909 (scm_top_level_lookup_closure_var): Renamed from
3910 scm_top_level_lookup_thunk_var.
3911 * root.c (mark_root): Uses changed.
3912 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
3913 * init.c (scm_start_stack): Uses changed.
3914 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
3915 Change scheme-visible name to *top-level-lookup-closure* from
3916 *top-level-lookup-thunk*.
3918 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
3920 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
3921 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
3923 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
3925 * gc.c (struct scm_heap_seg_data): Doc fixes.
3927 * gc.c (scm_gc_sweep): Empty all segments' freelists before
3928 sweeping. Then, prepend each segment's free cells to its
3929 freelist, rather than wiping out the old value. (Thanks to Marius
3932 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
3933 scm_check_freelist, scm_debug_newcell): New functions and
3934 variables, for debugging freelist problems.
3935 * pairs.h (SCM_NEWCELL): New debugging version added.
3936 * gc.h (scm_debug_newcell): Added extern declaration, used by
3937 debugging version of SCM_NEWCELL.
3939 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3941 On some systems <libc.h> conflicts with <unistd.h>, and should not
3942 be #included at all.
3943 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
3944 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
3945 * configure.in: Call it.
3946 * posix.c, filesys.c: Use its results to decide whether or not to
3948 * configure, scmconfig.h.in: Rebuilt with autoconf and
3951 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
3953 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
3954 pointer to the stdio stream before calling scm_setbuf0, so the
3955 latter will be able to retrieve it. I'm surprised this didn't
3956 segfault earlier. (Thanks to Christopher Lee.)
3958 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3960 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
3963 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3965 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
3966 number of stack narrowing specifier pairs. The first specifier in
3967 a pair controls inner border, the second the outer border. A
3968 number means cut that number of frames, a procedure object means
3969 cut until that object is found in operator position in a frame.
3971 * root.c (cwdr): Bugfix.
3973 * read.c: Recording of positions disabled by default.
3975 * procs.c (scm_closure_p): New function.
3977 * posix.c (scm_tmpnam): New function.
3979 * load.c: Added #include "throw.h".
3980 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
3983 * load.c, load.h (scm_read_and_eval_x): New function.
3985 * eval.c: Renamed debug option "deval" to "debug".
3987 (scm_eval_x): `eval!' is no longer accessible from the scheme
3988 level. Motivation: We can't allow operations which introduce
3989 glocs into the scheme level. Guile's type system can't handle
3990 these as data. Use `eval' or `read-and-eval!' as replacement.
3992 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
3993 SCM_CONSP since this is a macro!; Set vframe.prev to
3994 scm_last_debug_frame instead of 0. In this way we can look
3995 "above" the virtual start stack frame if we wish.
3996 (scm_debug_hang): New function: Useful for debugging Guile in
3997 certain tricky situations. Will probably be removed later...
3999 * debug.h: Changed semantics of debug option "backtrace". This
4000 option now only indicates whether we want automatic backtrace at
4003 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4005 * ports.c: #include "filesys.h"
4006 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
4008 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
4009 Motivation: This is system specific code which is related to file
4010 I/O. It also may use select. Added code by Gary Houston to
4011 detect presence of character in stdio buffers.
4013 * libguile.h: #include "libguile/libpath.h"
4015 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4016 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4017 SCM_SITE_DIR; Install libpath.h among the other include files.
4019 * load.c, load.h (scm_sys_package_data_dir): New function.
4021 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4023 * stacks.h: Bugfix: Don't use tail-array length field as stack
4024 length field! This screwed GC.
4026 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4028 * _scm.h: Added #ifndef around definition of macros min and max.
4030 * __scm.h: Added hooks for threads to plugin to in ints protection
4031 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4032 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4033 the main code in these macros duplicated and spread over multiple
4034 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4035 SCM_THREAD_SWITCHING_CODE.
4037 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4039 * snarf.h: New file.
4040 * guile-snarf.sh: New file.
4041 * Makefile.in (inner_h_files): Added snarf.h
4042 (ancillary, install, uninstall, distclean): Added actions for
4044 (.c.x): Use guile-snarf.
4045 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4046 (gen_c_files): Note that these depend on guile-snarf.
4047 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4048 now in "snarf.h". Added #include "snarf.h" to get them.
4049 * libguile.h: Added #include "snarf.h".
4050 (Patches applied and tweaked by Jim Blandy.)
4052 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4054 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4055 standards suggest against providing prototypes for system
4056 functions. Thanks to Greg Troxel.
4058 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4060 * strports.c (scm_eval_0str): New function.
4061 #include "read.h", to get prototype for scm_read.
4062 * Makefile.in (strports.o): Update dependencies.
4063 * strports.h: New prototype.
4065 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4066 scheme name from "int?" to "integer?". It seems to do the job.
4067 * numbers.h: Rename prototype too.
4068 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4071 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4072 scm_num_eq_p): Rename these according to R4RS conventions: call
4073 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4074 to making libguile R4RS compliant without ice-9...
4076 * load.c (scm_sys_search_load_path): Search for files under all
4077 extensions listed in the %load-extensions variable. If FILENAME
4078 is absolute, return it unchanged, without searching the load path.
4079 (scm_loc_load_extensions): New variable, pointing to
4080 %load-extensions' value cell.
4081 (scm_init_load): Initialize it, and the value it points to.
4082 (scm_primitive_load_path): Improve error reporting.
4084 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4085 of new Scheme variable %load-hook.
4086 (scm_primitive_load): Apply %load-hook to filename.
4088 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4090 * configure.in: add tests for figuring out whether buffered data
4091 is available in a FILE structure, which is needed by char-ready.
4093 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4096 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4097 exceptions using misc_error instead of syserror. It seems a bit
4098 odd to throw an exception if a string can't be found in the
4099 environment, but it's consistent with open-file, stat etc.
4100 (simpos.h): remove sys_ from getenv.
4102 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4103 occurs, throw an error instead of returning errno. Return value
4105 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4107 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4109 * filesys.c (scm_stat2scm): derive file type and permissions from
4110 the stat mode and append them to the returned vector.
4111 There isn't much overhead in doing this and it avoids the need to
4112 work with S_IRUSR et al. in Scheme.
4113 Define symbols scm_sym_regular etc.
4114 (scm_init_filesys): don't intern S_IRUSR etc.
4116 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4117 and s_primitive_load_path.
4119 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4121 * error.h: don't declare error symbols. prototype for scm_misc_error.
4123 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4126 * error.c: use SCM_SYMBOL to set up error keys.
4127 scm_misc_error: new procedure.
4129 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4131 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4132 between `#!' and `!#' is ignored.
4133 (skip_scsh_block_comment): New function.
4135 * feature.c (scm_set_program_arguments): New argument, FIRST.
4136 * feature.h: Update prototype.
4137 * init.c (scm_boot_guile_1): Pass new argument to
4138 scm_set_program_arguments.
4140 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4142 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4143 (scm_boot_guile): Call scm_set_program_arguments here, later than
4144 the old initialization.
4146 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4147 initialization procedure.
4148 - Delete in, out, err arguments; there are other perfectly good
4149 ways to override these when desired.
4150 - Delete result argument; this function shouldn't ever return.
4151 - Rename init_func argument to main_func, for less confusion.
4152 - Delete boot_cmd argument; main_func is more general.
4153 -Add 'closure' argument, to help people pass data to main_func
4154 without resorting to global variables.
4155 - Abort if reentered; don't bother returning an error code.
4156 - Call scm_init_standard_ports to set up the default/current
4157 standard ports; no need to pass them to scm_start_stack.
4158 - Remove code to evaluate the boot_cmd, and start the repl; let
4159 the user do something like that in main_func if they want.
4160 - Remove code to package up a return value; main_func can do any
4162 - Call exit (0), instead of returning.
4163 (scm_start_stack): Don't initialize the I/O ports here; that's
4164 weird. Delete in, out, err arguments. Move guts to
4165 scm_init_standard_ports, scm_stdio_to_port.
4166 (scm_init_standard_ports): New function, to set up current and
4167 default standard ports.
4168 (scm_start_stack, scm_restart_stack): Make these static.
4169 * init.h (scm_boot_guile): Adjust declaration.
4170 (scm_start_stack, scm_restart_stack): Remove externally
4171 visible declarations for these.
4172 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4174 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4175 written out several times in scm_start_stack.
4176 * fports.h: New declaration for the above.
4178 * feature.c (scm_set_program_arguments): New function.
4179 * feature.h: New declaration for the above.
4181 * ports.c: Formatting tweak.
4183 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4185 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4186 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4187 for obtaining the address of a car or cdr field. Motivation:
4188 &SCM_CXR make assumptions about the internal structure of the
4191 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4192 Motivation: see SCM_CXRLOC.
4194 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4195 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4196 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4197 Motivation: Safer use. Some other macros are defined in terms of
4198 these operations. If these are defined using the SCM_SETCXR
4199 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4200 to inefficiency and an <e1> with side-effects could potentially
4201 break. Also, these particular operations are heavily utilized in
4202 the garbage collector. In unoptimized code there will be a
4205 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4206 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4207 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4208 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4209 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4210 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4211 vports.c: Cleaned up use of pairs: Don't make any special
4212 assumptions about the internal structure of selectors and
4213 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4214 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4215 (Among other things, this change makes it easier to build Guile
4216 with certain compilers which have problems with casted lvalues.)
4218 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4220 * stacks.c: Improve selection of relevant stack frames when making
4221 a stack object. Introduce one level of indirection in the stack
4222 object to make it possible to "narrow" to a certain region of the
4223 stack. This facilitates making use of more clever algorithms (not
4224 implemented) for selecting relevant frames and gives a cleaner
4225 design since selection of frames can be done independently of
4226 extraction of frames from the real stack.
4227 (scm_stack_id): Also take #t as argument which means look at
4230 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4231 Turn n_tail into an integer directly representing current number
4232 of frames in stack. Add field tail.
4234 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4236 * debug.c (scm_make_memoized): Made it available at scheme level.
4237 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4238 SCM_NIMP before applying heavier predicates in argument checking.
4239 (scm_local_eval): Also take memoized object as argument.
4241 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4242 aren't created with zero length, but should such a strange
4243 creature suddenly turn up...
4245 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4247 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4248 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4250 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4252 * variable.c (scm_make_variable): Make the name hint optional, as
4254 (anonymous_variable_sym): Renamed from variable_sym. All uses
4257 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4258 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4259 of scm_primitive_load_path was also changed to
4260 "primitive-load-path", from "%try-load-path". Callers changed.
4261 We'd like to respect the convention that a function named
4262 "try-mumble" should behave just like the function called "mumble",
4263 but return #f instead of signalling some error.
4264 * load.h: Rename prototypes.
4266 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4268 * print.c (make_print_state, grow_print_state), print.h: Modified
4269 the print state representation: Don't use a tail array for
4270 recording of circular references. Resizing of the print state
4271 structure invalidates the print state pointer. To avoid passing
4272 around an indirect print state reference to all printing
4273 functions, we instead let the print state reference a resizable
4276 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4278 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4279 Don't crash when passed an improper list terminated by a
4280 non-immediate value.
4282 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4284 Allocate data for structures on an eight-byte boundary, as
4285 required by the tagging system.
4286 * struct.c (alloc_struct): New function.
4287 (scm_make_struct, scm_make_vtable_vtable): Call it.
4288 * struct.h (scm_struct_n_extra_words): Bump to 3.
4289 (scm_struct_i_ptr): New "field".
4290 * gc.c (scm_gc_sweep): When we need to free the data, use the
4291 information stored by alloc_struct to find the beginning of the
4292 block allocated to the structure, so we can free it.
4294 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4296 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4299 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4300 (scm_debug_info): New member: id.
4302 * stacks.c: Stacks are now represented as structs; Stacks have an
4303 id given to them by `start-stack'.
4304 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4306 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4307 Changed stack representation.
4309 * debug.c (scm_procedure_name): Try procedure property `name' for
4310 compiled closures aswell.
4312 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4314 * eval.c: scm_i_name moved to gsubr.c
4315 (scm_m_define): Record names of all kinds of procedure
4316 objects. (Earlier, only closures were recorded.)
4318 * procprop.h: Added declaration of scm_i_name.
4320 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4321 (scm_make_gsubr): Record names of compiled closures.
4323 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4325 * debug.c, debug.h: Removed obsolete code.
4327 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4328 stacks.c: Renamed regs --> scm_contregs.
4330 * print.c (scm_free_print_state): Cleanup print state before
4331 returning it to pool. It is better to do it here than in
4332 scm_prin1 since scm_prin1 is called often.
4334 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4335 s_set_source_property_x): Check that first argument is a pair or a
4338 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4339 scm_i_line, scm_i_column and scm_i_breakpoint global.
4341 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4342 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4345 * debug.h: Added debug object smob declaration and macro
4348 * configure.in: Build with backtrace.o and stacks.o if debug
4351 * Makefile.in: Added entries for new files: backtrace.c,
4352 backtrace.h, stacks.c and stacks.h.
4354 * symbols.c (scm_sym2ovcell): Fixed documentation.
4356 * _scm.h (min, max): Added.
4358 * async.c: Moved `min' macro to _scm.h.
4360 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4361 SCM_BACKTRACE_INDENT.
4363 * eval.c: Added new debug options `maxdepth' and `indent'.

4367 * print.h: Added selector SCM_PRINT_STATE.
4369 * print.c: New functions: scm_make_print_state,
4370 scm_free_print_state.
4372 * print.h: Added declarations for scm_make_print_state,
4373 scm_free_print_state.
4375 * debug.c (scm_m_start_stack): New acro.
4377 * debug.h: Small cleanup.
4379 * init.c (scm_boot_guile_1): Moved scm_init_debug below

4407 More prototype-related changes from Marius Vollmer:
4408 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4409 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4410 * ports.h (ptobfuns): Added prototypes. This means some casting in
4412 * fports.c: Added casts for initializations, since the functions
4413 are defined to take FILE * as their stream argument, not SCM.
4414 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4415 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4416 to `char *str_data' to conform to prototype.
4418 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4420 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4422 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4424 * stime.c, stime.h: use SCM_P method.
4426 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4428 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4429 be given at least two arguments. Insist that lst's last element
4430 be a list, but don't make any requirements of its predecessors.
4432 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4434 * eval.c (scm_nconc2last): Revert last change; there seems to be
4435 other stuff going on here.
4437 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4439 * eval.c (scm_nconc2last): Make sure that each element of lst
4440 (which is a list of argument lists, except for the tail) is a
4441 proper list, i.e., finite and terminated by '().
4443 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4445 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4448 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4449 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4452 * vectors.c (scm_make_vector): Fill vectors with the undefined
4453 value, to help make Guile Scheme code more portable to other
4456 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4457 * symbols.h, tags.h: Doc fixes.
4459 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4461 * async.c (scm_take_signal): Doc fixes.
4463 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4465 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4466 want to subtract it from the modulus; we just want to leave it
4469 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4471 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4474 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4476 * throw.c (scm_catch_apply): Finished implementation of
4479 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4481 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4483 (scm_init_filesys): set "i/o-extensions" feature.
4486 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4488 * Makefile.in (root.o): Correct dependencies.
4490 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4492 * Makefile.in: Added dependency entry for root.o.
4494 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4495 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4497 * init.c (scm_start_stack): Set initial root continuation number
4500 * procs.c: New function: scm_thunk_p.
4502 * procs.h: Added declarations of scm_thunk_p.
4504 * root.c: Renamed `call-with-new-root' -->
4505 `call-with-dynamic-root'.
4506 (cwdr): Removed allocation of new root state. This should be done
4507 separately by use of scm_make_root.
4508 (scm_apply_with_dynamic_root): New function: Does what it
4509 sounds like. Needed when spawning threads.
4511 * root.h: Added member last_debug_frame to root state.
4512 Added #include "libguile/debug.h"
4514 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4515 arguments. The motivation is that code in root.c needs catch
4516 functionality, and we want to avoid code duplication.
4517 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4518 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4519 handlers that run without popping the stack into the dynwind
4522 * throw.h: Added prototypes for scm_catch_apply and
4525 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4527 * root.h (scm_root, scm_set_root): Decouple thread support details
4528 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4529 SCM_SET_THREAD_LOCAL_DATA.
4531 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4532 and tortoise scanning loop.
4534 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4536 * Makefile.in: Rebuild dependencies.
4538 * libguile.h: #include "libguile/print.h" before "smob.h", since
4539 the latter uses the print_state structure.
4541 * throw.c (scm_ithrow): Use the correct variable when checking to
4542 see if a given element of scm_dynwinds is a valid catch.
4544 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4545 structure, abort; don't just silently ignore the garbage.
4547 * _scm.h: #include "print.h" here, since it seems to be used just
4549 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4550 strports.c, unif.h: Don't #include "print.h".
4552 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4554 * feature.h (scm_loc_features): Removed external declaration.
4555 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4557 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4559 * feature.c (scm_init_feature): Added threads feature (needs to be
4560 initialized here, since features doesn't exist when
4561 scm_init_threads is called).
4563 * libguile.h: Added #include "libguile/../threads/threads.h".
4564 (This is a kludge to get thread support working. This should be
4567 * configure.in, acconfig.h: Added flags for thread support.
4569 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4572 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4573 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4576 * _scm.h: Added conditional #include "threads.h"
4578 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4579 SCM_THREADS_SWITCHING_CODE.
4581 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4582 allocate the basic dynamic root object.
4583 (scm_boot_guile): Added call to scm_init_root.
4585 * root.c, root.h: Added root smob.
4586 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4587 functions: Implements dynamic roots mostly according to spec in
4588 SCM manual. Main difference is that the second argument is a
4589 throw handler rather than an error "thunk".
4591 * root.h: Added declaration of scm_init_root.
4593 * root.c: Added #include "genio.h", #include "smob.h", #include
4594 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4596 (scm_init_root): Added #include "root.x".
4598 * throw.c: Added #include "stackchk.h"
4599 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4600 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4601 can be used in scm_call_with_new_root; Added reenabling of stack
4602 checking when catching a throw.
4604 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4606 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4608 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4609 element is not found, as per R4RS.
4611 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4613 * list.c: Doc fixes throughout.
4615 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4617 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4618 declare the char * to be const. Avoids a warning in rgx.c.
4620 * ports.h: spelling fix.
4622 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4625 * load.c (scm_sys_try_load_path): throw an error if file not found
4626 (like it says it in NEWS).
4628 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4630 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4631 PROPS slot to '(), not #f; it's an empty alist.
4633 * throw.h, throw.c: Use SCM_P instead of #if hair.
4635 Remove special support for uncaught throws; see throw.c for
4637 * throw.c (uncaught_throw): New function.
4638 (scm_ithrow): Call uncaught_throw if we don't find a throw
4639 target; don't mess with scm_bad_throw_vcell.
4640 (scm_bad_throw_vcell): Variable deleted.
4641 (scm_init_throw): Don't initialize it.
4643 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4646 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4648 * numbers.c (scm_istr2int): If the number is short (as most
4649 numbers are), just call scm_small_istr2int to deal with it.
4650 (scm_small_istr2int): New function, created by un-#ifdefing the
4651 non-bignum version of scm_istr2int and renaming it.
4653 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4655 * load.c (scm_sys_try_load): don't check whether value returned
4656 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4657 Change the Scheme name from %try-load to primitive-load.
4659 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4660 Can avoid passing a message, allowing it to be derived in the
4661 error handler (e.g., if we want to throw to the key both from
4664 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4666 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4667 references now have a new appearance which is more compact and
4668 also gives a clue about what the target of the reference is.
4669 By setting parameters in the print state, more fancy printing can
4670 be achieved. This is used by the (not yet commited) backtrace
4673 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4675 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4678 * print.c: Added #include "struct.h". Removed function
4681 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4682 scm_iprin1. Removed prototype for scm_prlist.
4684 * arbiters.c (prinarb),
4685 async.c (print_async),
4686 debug.c (prindebugobj, prinmemoized),
4687 eval.c (prinprom, prinmacro),
4688 filesys.c (scm_fd_print, scm_dir_print),
4690 mallocs.c (prinmalloc),
4691 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4692 smob.h (scm_smobfuns),
4693 srcprop.c (prinsrcprops),
4695 unif.c, unif.h (scm_raprin1, rapr1),
4696 variable.c (prin_var): Changed argument `int writing' to
4697 `scm_print_state *pstate'.
4699 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4700 that it will be called before scm_init_print.
4702 * print.c (scm_prin1): Print states are now allocated when calling
4703 scm_prin1 and then passed around to all printing functions as an
4704 argument. A cache `print_state_pool' enables reuse of print
4706 (scm_make_print_state): New function.
4707 (scm_iprin1): Adaption to print states.
4708 (scm_iprlist): An initial "hare and tortoise" scan brings down
4709 time complexity to O (depth * N). (Better time complexity will be
4710 achieved when the printing code is completely rewritten.)
4712 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4714 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4715 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4716 it gets done whether or not the cache variable has a value.
4718 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4720 Distinguish #f and ().
4721 * __scm.h: #undef SICP.
4722 * pairs.h (SCM_EOL): Delete this definition, equating it with
4724 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4725 the value it used to have. Doc fixes, too.
4727 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4729 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4730 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4731 Lord's implementation of structs, allowing for tail arrays as
4732 described in the manual. Also fixed some bugs. (Both the interface
4733 and the implementation should be improved.)
4735 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4737 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4738 People who whish to see the source can do `(print-enable 'source)'.
4739 Removed #ifdef DEBUG_EXTENSIONS.
4741 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4743 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4744 integer (assuming for now accepting an integer is a good thing).
4746 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4747 %S will be used instead for write'ing arguments.
4749 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4750 asserts. fix a few other asserts.
4751 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4752 scm_uniform_vector_ref, scm_array_set_x,
4753 scm_dimensions_to_unform_array): change args in
4754 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4755 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4756 scm_substring_fill_x): likewise.
4757 gsubr.c (scm_gsubr_apply): likewise.
4758 eval.c (SCM_APPLY): likewise.
4760 * eval.c (4 places): replace scm_everr with lgh_error or
4763 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4764 scm_memory_error): new procedures.
4765 scm_everr: deleted. can use scm_wta, dropping first two args.
4766 scm_error: convert NULL subr to SCM_BOOL_F.
4768 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4771 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4774 * error.c, error.h: new error keys: scm_arg_type_key,
4775 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4777 scm_wta: reimplement using lgh_error instead of scm_everr.
4779 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4781 * gdbint.c: scm_lread now has one more argument.
4783 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4784 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4785 loading source from non-file ports, which, e. g., happens when
4786 using the Emacs interface).
4788 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4791 * read.c: Added code for recording of positions of source code
4792 expressions; New functions: recsexpr, scm_lreadrecparen;
4793 _scm_make_srcprops --> scm_make_srcprops
4794 (scm_flush_ws): Removed updating of positions counters. This work
4795 is already done by scm_gen_getc
4797 * read.h: Added prototype for scm_lreadrecparen
4799 * print.c: Added #include "alist.h"
4801 * eval.c: Added #include "hash.h"
4803 * eq.c: Added #include "ramap.h"
4805 * options.c: Documentation fixes.
4807 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
4808 (scm_init_srcprop): Adjusted size of initial source-whash. Name
4809 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
4810 --> scm_make_srcprops
4812 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
4813 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
4814 function calls in the definition of the whash access macros.
4816 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
4818 * init.c (scm_boot_guile): Add level of indirection to
4819 scm_boot_guile_1() to ensure that stack base pointer is properly
4820 initialized. There was no guarantee that variable i was the
4821 highest/lowest variable on stack (i.e. the call frame of
4822 scm_boot_guile was not completely protected from gc).
4824 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
4826 * ports.h (scm_port_table): put back file_name, it will be used to
4827 support debugging. Undo related changes in fports.c, ioext.c,
4830 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4832 * ports.h (scm_port_table): remove file_name member for now, it seems
4834 * fports.c (scm_open_file): don't set file_name in PTAB.
4835 (prinfport): don't use file_name in PTAB.
4836 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
4837 * ports.c (scm_add_to_port_table): don't intialize file_name.
4838 (scm_port_file_name): remove for now.
4839 * gc.c (scm_gc_mark): don't mark PTAB file_name.
4841 * fports.h (scm_mkfile): prototype deleted.
4842 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
4844 * debug.c, unif.c: use scm_out_of_range instead of
4845 wta for range errors (ASSERT still needs work).
4847 * error.c, error.h (scm_out_of_range): new procedure.
4849 * error.c, error.h (scm_out_of_range_key): new key.
4851 * posix.c (scm_sync): #else was missing.
4853 * error.c, error.h: append _key to names scm_num_overflow and
4856 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
4857 of consing an empty list.
4858 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
4859 of macros, saves code and string space.
4860 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
4861 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
4862 lower case. Rename scm_syserror_m to scm_syserror_msg.
4863 error.h: prototypes for new procedures.
4865 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
4867 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
4869 * error.c, error.h: setup scm_num_overflow key.
4871 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
4872 Remove definition of SCM_OVSCM_FLOW.
4874 * fports.c (scm_open_file): use SCM_SYSERROR_M.
4876 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
4877 explicit message and args.
4879 * error.c, error.h, __scm.h: change system_error_sym to
4882 * error.c (system_error_sym): remove leading %% from the Scheme name
4885 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
4887 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4889 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
4890 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
4891 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
4892 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
4893 renamed. (These were introduced by unsupervised name
4896 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4898 * print.c: Added code for detection of circular references during
4899 printing. (init_ref_stack, grow_ref_stack): New functions. Added
4900 a hook for printing of closures (accessible via print options).
4901 This leads to a split of calls to scm_iprin1 into two classes:
4902 elementary print operations (e. g. the code which prints a smob)
4903 still use scm_iprin1 while top level calls (like scm_display) use
4904 scm_prin1. scm_prin1 begins by clearing the data structure used
4905 to record reference information.
4907 * print.h: Added declarations of scm_prin1 and scm_prlist.
4909 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
4911 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
4913 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
4915 * error.c (err_head): scm_iprin1 --> scm_prin1
4917 * debug.c: Adjusted header comment.
4921 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4923 * strerror.c: Doc fix.
4925 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4927 * gdbint.c (gdb_read): Now possible to run during GC.
4928 (unmark_port, remark_port): New functions.
4930 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
4932 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
4933 of allocating a new string object. Also, increase size by
4934 the factor 2 instead of 1.5.
4936 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
4938 * __scm.h (SCM_P): Corrected to run under traditional C.
4940 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
4943 * async.c: Calls to scm_sysintern corrected.
4945 * async.h (scm_async_clock): Redundant declaration removed.
4947 * continuations.c (scm_dynthrow): Redundant declaration removed.
4949 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
4950 Definition typos corrected.
4952 * debug.h: Missing declarations of functions in debug.c added
4955 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
4956 Missing declarations to functions in eval.c added.
4958 * filesys.c: Possibly uninitialized variable rv.
4960 * gc.h (scm_object_addr, scm_unhash_name): Missing
4961 declarations of functions defined in gc.c added.
4963 * genio.c: Possible typos str_data -> wstr_data. ???
4965 * genio.c: Possibly unintended shadowing of local variable
4966 `int c' (gotos out of scope of inner `c'). ???
4968 * init.c: Uninitialized `SCM last' may be used.
4970 * ioext.h: (scm_sys_isatty_p): Typo.
4972 * list.h (scm_list_head): Missing prototype for function in
4975 * numbers.c (scm_two_doubles): Changed from extern to static
4976 (is used only within numbers.c).
4978 * numbers.h: Repeated declarations removed.
4980 * ports.h (scm_close_all_ports_except): Declaration for the
4981 function defined in ports.c added.
4983 * posix.h: Missing declarations added.
4985 * procs.h (scm_make_subr_opt): Missing declaration added.
4987 * socket.h (scm_sys_gethost): Missing declaration added.
4989 * socket.h: Redundant declarations removed (they are in fdsocket.h).
4991 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
4992 Missing declarations added.
4994 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
4996 * struct.c: Uninitialized variable `SCM answer' may be used.
4998 * unif.c (l2ra): Declaration prototype.
5000 * unif.c (scm_array_equal_p): Dummy definition removed (it is
5001 defined in ramap.c).
5003 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
5004 Redundant declarations removed (they are in ramap.h).
5006 * variable.h (scm_make_udvariable,
5007 scm_make_undefined_variable): Declaration corrected to
5008 correspond variable.c.
5010 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
5011 Missing declarations added.
5013 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5015 * Makefile.in (distclean): Don't forget to delete fd.h.
5017 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5019 * fd.h.in, tags.h: Trivial cleanups.
5021 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5022 marksweep.h just declared functions from gc.c.
5023 * gc.h, libguile.h: Don't #include "marksweep.h".
5024 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5025 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5026 dependencies updated.
5028 * libguile.h: Don't #include "files.h"; it's been deleted.
5030 * files.c (scm_sys_delete_file): Moved to filesys.c.
5031 File is now empty; deleted.
5033 * filesys.c: scm_sys_delete_file is now here. Remove
5034 #if's; they seem to rely on remnants of an old portability
5035 regimen. If the problems come up again, solve them properly,
5036 using autoconf. Specifically: Don't test M_SYSV, and #define
5037 remove to be unlink if it's #defined; don't use remove just
5038 because HAVE_STDC_HEADERS is #defined.
5039 * filesys.h: Add declarations for scm_sys_delete_file.
5040 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5041 files.o, files.h, files.c, and files.x.
5042 * init.c: Don't #include "files.h", and don't call scm_init_files.
5044 Use SCM_P instead of PROTO; the latter intrudes on the user's
5046 * params.h: Deleted; definition of SCM_P moved to...
5047 * __scm.h: ... here, where it replaces PROTO macro.
5048 * libguile.h, smob.h: Don't #include "params.h".
5049 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5050 smob.h: Fix prototypes accordingly.
5051 * Makefile.in: Update dependencies.
5052 (inner_h_files): Remove params.h.
5054 * gc.c: #include "gc.h"; every module should include its header,
5055 to let the compiler cross-check the declarations against the
5058 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5059 simpos.h: #include "libguile/__scm.h".
5061 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5063 * init.c: Don't forget to #include smob.h and init.h.
5064 * Makefile.in: Dependencies updated.
5066 * smob.h: Use PROTO instead of #if __STDC__.
5068 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5070 * __scm.h: Doc fixes.
5072 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5073 <angles>; this allows `make depends' to work properly.
5075 * libguile.h: #include smob.h and pairs.h before the others; they
5076 define typedefs used by other headers.
5078 C files should #include only the header files they need, not
5079 libguile.h (which #includes all the header files); the pointless
5080 recompilation was wasting my time.
5081 * Makefile.in (all .o dependency lists): Regenerated.
5082 * libguile.h: Don't try to get a definition for size_t here...
5083 * __scm.h: Do it here.
5084 * _scm.h: Since this is the internal libguile header, put things
5085 here that all (or a majority) of the libguile files will want.
5086 Don't #include <libguile.h> here; that generates dependencies on
5087 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5088 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5089 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5186 * weaks.c: Get "weaks.h".
5188 * stackchk.h: #include "libguile/debug.h",
5190 * print.h, read.h: #include "options.h", since everyone who uses
5191 either of these files will need that.
5193 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5194 anyone who uses this file will need them to define the smob
5195 printing functions. Also, get markers.h, since people will need
5196 to #define the mark functions.
5198 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5199 * ports.h: ... to here.
5201 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5202 don't rely on archaic C default type rules.
5204 * fports.h: #include "libguile/ports.h", since you need that in
5205 order to parse this.
5207 * genio.h: #include "libguile/print.h", because you need that to
5208 parse this; don't bother #including "ports.h", since print.h gets
5211 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5213 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5214 this; it's now a reference to an element of *scm_root.
5216 * debug.h: Don't #include "options.h"; the compiler won't be able
5217 to find that once the headers are installed; instead, #include
5218 "libguile/options.h".
5219 * gc.h: Same, with marksweep.h.
5220 * mbstrings.h: Same, with symbols.h.
5221 * scmhob.h: Same, with _scm.h.
5222 * smob.h: Same, with params.h.
5224 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5225 C files; there's no need for this, and it forces recompilations
5228 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5230 * error.c (scm_error): declare scm_error_callback.
5232 * error.h: prototype for scm_error_callback.
5234 * __scm.h: define lgh_error.
5235 (SCM_SYSERROR): redefine using lgh_error.
5237 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5239 * error.c (scm_error): new procedure.
5241 * error.h: prototype for scm_error.
5243 * Makefile.in (install): install scmconfig.h from the current
5244 directory, not $(srcdir).
5246 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5248 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5249 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5250 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

5256 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5257 vports.h, weaks.h: #include "libguile/__scm.h", not
5258 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5259 dependencies are within libguile properly.
5261 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5263 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5264 when scmconfig.h doesn't exist.
5266 * load.c (scm_sys_try_load): Correct spelling.
5268 * feature.c (scm_loc_features): Make this static.
5270 * Makefile.in (libpath.h): Omit trailing slash from path. We
5271 shouldn't require it of users, so why put it here?
5273 Move code to initialize and search %load-path from ice-9 to C
5274 code, so we can use the load-path to find the ice-9 boot code;
5275 this makes it easier to run Guile without installing it. See
5276 corresponding changes in guile/Makefile.in.
5277 * feature.c: Move stuff concerned with the load path to load.c.
5278 (scm_compiled_library_path): Deleted.
5279 Don't #include libpath.h here.
5280 * feature.h: Don't mention scm_compiled_library_path.
5281 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5282 <sys/stat.h>, and <unistd.h> (if present).
5283 (R_OK): #define if the system hasn't deigned to.
5284 (scm_loc_load_path): New variable.
5285 (scm_init_load_path, scm_sys_search_load_path,
5286 scm_sys_try_load_path): New functions.
5287 (scm_init_load): Initialize scm_loc_load_path to point to the
5288 value cell of the Scheme %load-path variable.
5289 * load.h: Add declarations for scm_sys_search_load_path,
5290 scm_sys_try_load_path.
5291 * init.c: Call scm_init_load_path.
5292 * Makefile.in (feature.o, load.o): Dependencies updated.
5294 * load.c, load.h: Rewrite using PROTO macro.
5296 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5298 * gc.c (scm_cellp): New function: C predicate to determine if an
5299 SCM value can be regarded as a pointer to a cell on the heap.
5301 * gc.h: Added declaration of scm_cellp.
5303 * gdb_interface.h: New file: The GDB interface header from the GDB
5306 * gdbint.c: New file: GDB interface.
5308 * gdbint.h: New file: GDB interface.
5310 * libguile.h: Added #include <libguile/gdbint.h>.
5312 * init.c (scm_boot_guile): Added scm_init_gdbint.
5314 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5315 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5316 found if object files and source are kept separate).
5318 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5320 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5322 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5324 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5325 TK_SRC_DIR; they're not relevant any more.
5327 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5328 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5330 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5332 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5333 search path, so we can find the <libguile/MUMBLE.h> headers.
5335 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5337 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5338 implicit in the .c.o rule.
5339 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5342 Put the library path in a header file, instead of passing it on
5343 the command line in every compilation.
5344 * Makefile.in (libpath.h): New target.
5345 (feature.o): Depend on libpath.h.
5346 (clean): Delete libpath.h.
5347 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5348 * feature.c: ... #include "libpath.h" here.
5349 * .cvsignore: Ignore libpath.h.
5351 Don't install the unwashed masses of Guile header files in the
5352 main #include path; put most of them in a subdirectory called
5353 'libguile'. This avoids naming conflicts between Guile header
5354 files and system header files (of which there were a few).
5355 * Makefile.in (pkgincludedir): Deleted.
5356 (innerincludedir): New variable; this and $(includedir) are enough.
5357 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5358 (installed_h_files): Divide this up. Now this variable lists
5359 those header files which should go into $(includedir) (i.e. appear
5360 directly in the #include path), and ...
5361 (inner_h_files): ... this new variable says which files appear in
5362 a subdirectory, and are referred to as <libguile/mumble.h>.
5363 (h_files): List them both.
5364 (install): Create innerincludedir, not pkgincludedir. Put
5365 the installed_h_files and inner_h_files in their proper places.
5366 (uninstall): Corresponding changes.
5367 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5368 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5369 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5370 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5371 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5372 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5373 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5374 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5375 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5376 vports.h, weaks.h: Find __scm.h in its new location.
5377 * __scm.h: Find scmconfig.h and tags.h in their new locations
5378 (they're both "inner" files).
5380 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5382 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5384 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5386 * posix.c: Doc fixes.
5388 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5390 * socket.c: Don't include a prototype for inet_aton; just use a
5391 K&R style declaration, to avoid warnings but minimize the chance
5392 of conflicts with the system.
5394 On NextStep, <utime.h> doesn't define struct utime, unless we
5395 #define _POSIX_SOURCE before #including it.
5396 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5397 * acconfig.h: New comment text for above CPP symbol.
5398 * configure.in: Call it.
5399 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5401 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5403 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5404 testing for __EMX__.
5406 * posix.c: #include <libc.h>, if it exists.
5408 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5409 don't even know if the latter exists.
5411 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5412 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5413 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5415 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5417 (scm_init_posix): Use them when initializing the Scheme constants
5420 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5422 * Makefile.in (libdir, includedir, bindir): Use the
5423 autoconf-supplied values, instead of deriving them ourselves.
5424 (pkgincludedir, datadir, pkgdatadir): New variables.
5425 (install, uninstall): Put the header files in a special
5426 subdirectory, not in the main search path.
5428 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5429 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5431 * Makefile.in (IMPLPATH): Deleted; never used.
5433 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5434 on the Tcl/Tk source any more.
5435 (INCLUDE_CFLAGS): Remove references to the above.
5437 * Makefile.in (version.o): Corrected dependencies.
5439 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5441 * libguile.h: #include "version.h"
5443 * init.c (scm_boot_guile): Call scm_init_version.
5444 * gscm.c (gscm_run_scm): Call scm_init_version.
5446 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5447 GUILE_VERSION): AC_DEFINE these.
5448 (acconfig.h): #undef the above symbols.
5450 * Makefile.in (libobjs): Add version.o.
5451 (installed_h_files): Add version.h.
5452 (c_files): Add version.c.
5453 (gen_c_files): Add version.x.
5454 (version.o): New rule.
5455 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5456 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
5457 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
5458 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
5459 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
5460 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
5461 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
5462 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
5463 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
5464 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5465 weaks.o): Add version.h to dependency lists.
5466 (markers.o): Remove duplicate rule.
5468 * version.h: New file.
5470 * version.c: New file.
5472 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5474 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5475 array; use it appropriately. Since GCC is quite happy to
5476 subscript functions, it never warned us about this; we should use
5477 -Wpointer-arith in the future. I guess we never tested
5480 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5482 * socket.c: Doc and copyright fixes.
5484 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5486 * debug.c: Fixed and improved gdb support.
5488 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5490 * socket.c: Added declaration of inet_aton to avoid compiler
5491 warning. (Hope this solution is correct.)
5493 * stime.c: Added declaration of ftime. (This is missing in
5496 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5498 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5500 * Makefile.in (c_files): add strerror.c.
5502 * strerror.c: new file from Emacs' sysdep.c.
5503 maybe configure should also check for sys_errlist.
5505 * configure.in (AC_REPLACE_FUNCS): add strerror.
5507 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5509 * debug.c (scm_init_debug): Added initialization for
5510 scm_evaluator_traps.
5512 * debug.h, debug.c: Various name changes.
5513 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5514 "debug-options-interface". See commentary in options.c.
5516 * options.h, options.c: Options now have documentation strings.
5517 Also added a long explanatory commentary.
5519 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5522 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5523 last_debug_info_frame is now updated in all cases.
5525 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5528 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5530 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5531 Added option STACK_CHECKING.
5533 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5535 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5537 * __scm.h: Removed symbols for debugging support.
5539 * acconfig.h: Added symbols for debugging support.
5541 * configure.in: Added user option for debugging support.
5542 --enable-debug will include the debugging code into libguile.a.
5544 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5545 scm_relocate_chunk_to_heap.
5547 * debug.c: New file: low-level debugging support. It also
5548 includes support for debugging with gdb. (The extensions to gdb
5549 are written by Per Bothner at Cygnus.)
5551 * debug.h: New file: low-level debugging support.
5553 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5554 argument pairs. Extensive modifications to the debugging
5555 evaluator. Added "SECTION:" commentaries to clarify what happens
5556 when, during double compilation. Renamed EVALIMP --> EVALIM.
5557 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5558 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5559 the beginning of the file. New procedure: scm_unmemocopy.
5560 Added some global state variables needed by the debugging
5561 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5562 check_entry, check_apply, check_exit, debug_options and
5563 evaluator_traps. New acro: undefine.
5565 * eval.h: Renamed EVAL --> XEVAL.
5567 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5568 --> scm_make_weak_key_hash_table.
5570 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5571 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5573 * libguile.h: Conditionally include debug.h
5575 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5576 scm_object_properties shouldn't return handle. `handle' now gets
5577 initialized in scm_set_object_properties_x. scm_object_properties
5578 doesn't any longer create an entry in scm_object_whash.
5580 * options.c: New file: handling of run time options.
5582 * options.h: New file: handling of run time options.
5584 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5586 * print.c: New procedure: scm_print_options
5588 * print.h: Defines for print options.
5590 * read.c: New procedure: scm_read_options
5592 * read.h: Defines for reader options.
5594 * root.h: Added scm_source_whash among scm_sys_protects.
5596 * srcprop.c: New file: source properties.
5598 * srcprop.h: New file: source properties.
5600 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5601 (Bug found by A. Green.)
5603 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5605 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5607 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5609 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5611 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5612 and should be called by the final client.
5614 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5616 * gc.h: Use the PROTO macro when declaring functions.
5617 * gc.c: Use the PROTO macro when declaring static functions.
5618 Remove the CPP hair around function definitions.
5620 * gc.c (scm_init_storage): Initialize scm_asyncs.
5622 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5623 preprocessor symbol; "__scm.h" is where it might get #defined.
5624 * __scm.h: Similar: #include <scmconfig.h> before testing
5627 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5629 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5631 * init.c (scm_boot_guile): Add init_func argument; call
5632 (*init_func) instead of calling scm_appinit; it's ucky to
5633 hard-code names for the user's procedures.
5634 * init.h (scm_boot_guile): Adjust declaration.
5636 * __scm.h (PROTO): New macro, for declaring functions with
5639 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5640 eliminate all the __STDC__ conditionals.
5641 (scm_boot_guile): Add declaration.
5642 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5643 Remove __STDC__ conditionals around function definitions; the
5644 declarations in init.h will provide the same information, more
5647 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5648 complain about it in the error message; the error message is
5649 adequate without that note, and there's nothing the user can do
5652 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5654 * Makefile.in (ancillary): Drop def.sed.
5656 * posix.c (scm_init_posix): Use numeric values, rather than
5657 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5658 F_OK. The symbols aren't available on some systems, and I'm
5659 pretty sure their values are fixed by common widespread practice.
5660 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5662 More functions unavailable on some systems.
5663 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5664 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5666 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5667 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5668 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5669 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5670 stub that signals an error as the #else.
5672 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
5674 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
5676 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
5678 * unif.c: include ramap.h.
5680 * read.c (endif): case_insensative_p renamed case_insensitive_p.
5682 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
5684 * ports.c: include sys/ioctl.h.
5686 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
5688 * configure.in: check for sys/ioctl.h.
5690 * ports.c: include <malloc.h> not "malloc.h".
5692 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5694 * fports.c: remove ttyname and tmpnam declarations.
5696 * posix.c: fewer ttyname declarations.
5698 * fports.c: include <string.h> not "string.h".
5700 * init.c, ioext.c: include string.h and unistd.h.
5702 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5704 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
5705 genio.c, simpos.c, vports.c: include string.h.
5707 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
5709 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
5711 (scm_addr_buffer_size): change type from scm_sizet to int.
5712 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
5713 from scm_sizet to int.
5715 * error.c: include unistd.h.
5717 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
5720 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
5722 * __scm.hd, def.sed: deleted.
5724 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
5726 Changes for NeXT, suggested by Robert Brown.
5727 * configure.in: Call AC_TYPE_MODE_T.
5728 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
5729 NeXT. Put header file list in alphabetical order.
5730 * configure, scmconfig.h.in: Regenerated.
5731 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
5733 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
5736 * acconfig.h: New file, providing documentation for the CPP
5737 symbols defined in configure.in
5738 * acconfig-1.5.h: Removed; superceded by the above.
5740 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
5742 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
5744 * fports.c (scm_open_file): don't return #f, throw error.
5746 * ioext.c (fileno): renamed from %fileno.
5747 (soft-fileno): deleted.
5749 * ports.c (scm_port_revealed): don't need to check for -1 from
5751 (scm_set_port_revealed_x): return unspecified, not #f.
5753 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
5755 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
5757 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
5759 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
5761 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5763 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5764 This is necessary on Ultrix, and doesn't hurt portability.
5766 * Makefile.in (dist-dir): New target, implementing a new dist system.
5767 (installed_h_files): Put in alphabetical order.
5768 Remove duplicate entries for markers.h and unif.h.
5769 (c_files): Remove duplicate entries for markers.c.
5770 (ancillary): Renamed from anillery; all uses changed. Remove

5774 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5776 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5777 every if must have an else, or else the whole command has a

5849 * gscm.h: gscm_mkarray eliminated (presumably was not being used

5867 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
5868 handled correctly (SCM_FREEP was applied to them) -- test for

6037 initialization to fix a race condition.
6039 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

6066 The weird symbol syntax is also a bit bogus (emacs doesn't quite
