1 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
3 * genio.c (scm_do_read_line): Count lines correctly when the file
4 doesn't end in a newline.
6 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
8 * genio.c (scm_do_read_line): Maintain the line count correctly.
9 (Thanks to Harvey J. Stein and Greg Harvey.)
11 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
14 * numbers.c (big2str): Protect t from garbage collection until
15 we're done. (Thanks to Gary Houston.)
17 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
19 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
21 * Makefile.in: Regenerated.
23 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
24 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
27 Do magic to mix reads and writes on stdio FILE-based ports.
28 (Thanks to Christian Lynbech.)
29 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
31 (pre_read, pre_write): New functions.
32 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
33 local_fputs): Call them.
34 (local_fflush): Mark the port as ready for reading and writing.
35 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
36 flags on new port objects. This might not be accurate --- who
37 knows what state the FILE * is in when we get it --- but it won't
38 do extraneous calls to fflush or fseek, so it's no worse than the
39 behavior before this change.
40 * ports.h: Add comment.
42 Centralize the creation of port objects based on stdio FILE * in
43 fports.c; don't just throw them together anywhere.
44 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
45 what the rest of Guile wants. Don't set the revealed count;
46 that's only appropriate for stdin, stdout, stderr.
47 (scm_standard_stream_to_port): This function does set the revealed
49 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
50 not scm_stdio_to_port.
51 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
52 * fports.c (scm_open_file): Same.
53 * posix.c (scm_pipe): Same.
54 * socket.c (scm_sock_fd_to_port): Same.
55 * ioext.c (scm_fdopen): Same.
56 (scm_freopen): Moved from here to...
57 * fports.c (scm_freopen): ... here. This is really something that
58 munges the internals of an fport, so it should go here.
59 * fports.h (scm_stdio_to_port): Adjust prototype.
60 (scm_standard_stream_to_port, scm_freopen): New protoypes.
61 * ioext.h (scm_freopen): Prototype removed.
63 * filesys.c (set_element, get_element): This can work on both pipe
64 and file ports, so use SCM_FPORTP to typecheck, instead of testing
67 * scmconfig.h.in: Regenerated.
69 Change the definition of the functions in scm_ptobfuns so that
70 they get passed the port object, not the port's stream.
71 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
72 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
73 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
74 Pass the port itself to the scm_ptobs function.
75 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
76 scm_generic_fgets): Same.
77 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
78 getc_void_port, fgets_void_port, close_void_port): Just change the
79 argument names; these functions don't really do anything.
80 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
81 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
82 port as an argument, and use SCM_STREAM to get the stdio FILE *.
83 Also, use prototyped definitions, and get rid of the extra
85 (scm_fptob, scm_pipob): We don't need casts here any more.
86 * strports.c (prinstpt): Use prototype declarations.
87 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
88 and use SCM_STREAM to get the string info. Also, use prototyped
89 definitions, and get rid of the extra declarations.
90 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
93 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
94 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
96 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
97 scm_fgets, for consistency.
98 (scm_fptop, scm_pipob): References updated.
100 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
102 Include the source location in error messages for scripts.
103 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
104 stack is still there when we catch the error.
105 * throw.c (handler_message): If we are handling an error with a
106 message, then put together the proper arguments and call
107 scm_display_error, instead of scm_display_error_message. That
108 displays source location, if it can find it.
110 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
112 * gc.c (scm_unprotect_object): Change this so that calls to
113 scm_protect_object and scm_unprotect_object nest properly.
114 (scm_protect_object): Doc fixes.
116 * strings.c (scm_string_set_x): Require the argument to be a
117 writable string, not a substring or a symbol.
118 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
119 (Thanks to John Redford and Charbel Jacquin.)
121 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
123 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
125 * eval.c (safe_setjmp): Remove this misunderstanding.
126 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
129 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
131 * libguile.h: Mark these as C declarations, for compilation by C++
134 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
135 __cplusplus clause. I seriously doubt this ever worked the way
136 the author seems to have intended.
138 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
140 Utterly needless cleanups to hopelessly messy code.
141 * ports.c: Doc fixes.
142 (scm_fflush): Moved to ...
143 * genio.c (scm_fflush): ... here, amongst all the other port
144 method invocation functions.
145 * genio.h, ports.h: The prototype moves too.
147 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
149 * backtrace.c (display_error_body): The current frame does not
150 always have a parent frame; consider a function called directly
151 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
154 * alloca.c (alloca): Undo yesterday's changes, and simply call
155 malloc directly for storage, and abort if we don't get what we
156 want. The situation is much simpler --- just call malloc. Emacs
157 has bizarre/evil requirements (signal handlers might malloc unless
158 you set this global flag, so you have to set the flag around all
159 calls to malloc) which we are certainly not going to conform to,
160 so we can do the simple and obvious thing.
162 * coop.c (coop_condition_variable_wait): Make this function
163 static. It's only useful internally --- you should never just
164 wait on a condition variable.
165 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
167 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
169 * unif.c (scm_array_set_x): Accept any kind of number as an
170 element for a uniform vector of doubles. This is more consistent
171 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
173 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
174 works; I can't conveniently test it myself. (Thanks to Dvid
175 Tillman for the bug report.)
179 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
180 from here, not from scm_compile_shell_switches (which is a pretty
181 dumb place to do it).
182 (scm_load_startup_files): New function.
183 (scm_ice_9_already_loaded): Variable moved to here from script.c.
184 * script.c (scm_compile_shell_switches): Don't load the startup
186 (scm_ice_9_already_loaded): Variable moved.
187 * init.c (scm_load_startup_files): Prototype for new function.
188 * gh_init.c (gh_enter): Doc fix.
190 1998-10-03 <jimb@savonarola.red-bean.com>
192 Some anti-warning changes from Greg Harvey.
193 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
194 warnings when it doesn't understand our NORETURN declarations in
196 * posix.c (scm_mknod): Similar.
198 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
200 * posix.c (scm_getpwuid): If we can't find an entry, return our
201 own message, instead of using scm_syserror --- the getpwMUMBLE
202 functions don't set `errno' to anything interesting.
204 1998-10-03 <jimb@savonarola.red-bean.com>
206 Get rid of warnings from the cooperative threading system.
207 * threads.h (scm_single_thread_p, scm_yield,
208 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
209 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
210 scm_wait_condition_variable, scm_signal_condition_variable): Add
211 prototypes for these Scheme-visible functions.
212 * coop-defs.h (coop_next_runnable_thread,
213 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
214 Prototypes for these here, even though they're from iselect.c.
215 (coop_condition_variable_wait, coop_join): Add prototypes.
216 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
217 scm_threads_free_condvar): Make these smob functions static.
218 * coop-threads.h (coop_init): Give this a real prototype.
219 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
220 (coop_next_runnable_thread): No need to provide prototype; it's in
223 * scmconfig.h.in: .detarenegeR
225 * iselect.c, threads.c: Doc fixes.
227 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
229 * Makefile.in: Regenerated with a patched automake, to get
230 dependency generation right when using EGCS.
232 * inet_aton.c (inet_aton): Add prototype, to remove compiler
233 warning. (Thanks to Robert Pluim.)
235 * inet_aton.c (inet_aton): Reassure the compiler that the
236 arguments to the <ctype.h> macros are all unsigned characters, not
239 1998-10-03 <jimb@savonarola.red-bean.com>
241 Getting rid of more warnings...
242 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
243 today's change to ../configure.in.
244 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
245 * scmconfig.h.in: Regenertaded.de.,.__
246 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
247 (scm_localtime, scm_mktime): Use a const char * to manipulate the
250 * readline.c: Doc fix.
251 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
252 * readline.h (scm_filename_completion_function): Add prototype.
253 (scm_init_readline): Make this into a prototype.
255 * readline.c (scm_filename_completion_function): Use SCM_PROC to
256 declare this, instead of calling scm_make_subr manually.
258 1998-10-02 <jimb@savonarola.red-bean.com>
260 * readline.h (scm_init_readline): Add prototype for this.
261 (scm_init_readline): Make this a real prototype.
263 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
265 Warning fixes from Maciej Stachowiak:
266 * backtrace.h (scm_display_application, scm_backtrace): Add
268 * debug.c (scm_m_start_stack): Make this function static.
269 * fluids.h (scm_fluid_p): Add prototype.
270 * procprop.c (scm_i_procedure_arity): Make this function static.
271 * regex-posix.c (scm_regexp_error_msg): Make this function static.
272 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
273 * root.h (scm_dynamic_root): Add external prototype.
274 * scmsigs.h (scm_usleep): Add external prototype.
275 * script.h (scm_init_script): Use prototype, not K&R decl.
276 * stacks.h (scm_stack_id): Add external prototype.
277 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
279 1998-09-30 Mark Galassi <rosalia@cygnus.com>
281 * gh.h: took out the definitions of vset and vref, since they are
282 replaced by the proper vector routines that correspond to the R4RS
285 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
287 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
288 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
289 third argument, a C expression that should result in a SCM value,
290 which is used to initialize the variable. Reimplemented
291 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
294 * version.h (scm_libguile_config_stamp): Add prototype.
295 (From Maciej Stachowiak.)
297 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
299 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
300 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
302 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
304 * print.c (scm_iprin1): Rather than having one i, and using it in
305 several places, declare a fresh i local to each block where it is
306 used, and give it a signedness appropriate to its use in each case.
309 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
312 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
313 signed/unsigned clashes.
315 * posix.h (scm_tmpnam): Added prototype.
317 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
318 scm_make_subclass_object): Add external prototypes.
320 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
321 comparison is okay here.
323 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
325 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
326 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
328 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
331 * load.c (swap_port): Make this function static.
333 * load.c (scm_search_path): Make max_path_len and max_ext_len
334 unsigned, since they're compared against string sizes.
336 * load.c (init_build_info): Make i unsigned.
338 * ioext.h (scm_read_line): Add prototype.
340 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
341 scm_hash_fn_remove_x): Make hash bucket index local variable k
342 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
343 accurately as possible.
345 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
346 comparisons, and range checking to make sure those casts are
349 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
350 signed/unsigned comparisons.
352 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
353 avoid signed/unsigned comparisons.
354 * smob.h (scm_numsmob): Change extern declaration to match.
356 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
357 avoid signed/unsigned comparisons.
358 * ports.h (scm_numptob): Change extern declaration to match.
359 (scm_current_load_port, scm_set_port_line_x,
360 scm_set_port_column_x): New prototypes.
362 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
363 test code, and it causes warnings.
365 * gh.h (gh_int2scmb, gh_uniform_vector_length,
366 gh_uniform_vector_ref): Added prototypes.
368 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
369 debugging support unconditionally. That's backtrace.c, stack.c,
370 debug.c, and srcprop.c.
371 (EXTRA_libguile_la_SOURCES): Omit those from here.
372 * Makefile.in: Regenerated.
374 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
376 * options.c (scm_options): Bugfix: Allow empty list of options!
378 * debug.c, debug.h (scm_single_step): Removed.
379 (scm_with_traps): New procedure. This procedure could easily be
380 written in Scheme but needs to be highly optimized.
382 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
384 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
385 Check SCM_TRAPS_P before trapping.
387 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
389 Changes to avoid signed/unsigned comparison warnings.
390 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
391 (scm_gc_sweep): Make n and j local to the blocks they're used in,
392 so they can have appropriate types for each application. Make i
393 signed. Use initializers in some spots. I'll probably pay for
395 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
396 (scm_must_realloc): Make nm unsigned.
397 (init_heap_seg): Make new_seg_index and n_new_objects signed.
398 (scm_init_storage): Use prototype-style definition, and make the
400 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
401 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
403 * filesys.c (scm_readlink): Make local vars rv and size ints, to
404 avoid signed/unsigned comparison warnings, and because the return
405 value of readlink may be -1. Don't bother casting the third
406 argument to readlink.
408 * filesys.c (scm_dirname, scm_basename): Move these to their own
409 page, at the end of the file.
410 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
412 * eval.h (scm_eval_options_interface): Add external prototype for this.
413 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
415 * eval.c (scm_lookupcar1): Make this static.
417 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
418 Make these prototype declarations, not K&R-style.
420 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
421 unsigned comparison warning.
423 * appinit.c: File removed. It had a single function in it, empty,
424 whose reason for existence is explained in no documentation or
425 comment. I think it's there as a default for some Tcl-style
426 initialization, but Tcl abandoned that approach a while ago.
427 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
428 (BUILT_SOURCES): Remove appinit.x.
429 * Makefile.in: Regenerated.
431 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
433 * Makefile.in: Regenerated using the last public version of
434 automake, not the hacked Cygnus version.
436 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
438 Remove Totoro kludge.
439 * Makefile.in, scmconfig.h.in: Regenerated.
440 * init.c, readline.c: Don't check if TOTORO is #defined.
442 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
444 * Makefile.am: Adjust for new thread configuration system.
445 (INCLUDES): Include the value of THREAD_CPPFLAGS.
446 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
448 (THREAD_LIBS): Definition deleted; automake will generate such
449 things automatically.
450 * Makefile.in: Regenerated.
452 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
454 Simplify smob and port marking; set the mark bit in the generic
455 marking code, and make marker routines only responsible for
456 turning up outgoing pointers.
457 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
458 before calling the marking function. Don't call the marking
459 function if it's zero.
460 * markers.c (scm_mark0): Just return #f. This function isn't
461 necessary at all now, but it's harmless to call it. We'll leave
462 it in so other folks' code doesn't croak at link time.
463 (scm_markcdr): Don't call SCM_SETGC8MARK.
464 * async.c (mark_async): Don't call SCM_SETGC8MARK.
465 * dynl.c (mark_dynl_obj): Same.
466 * root.c (mark_root): Same.
467 * srcprop.c (marksrcprops): Same.
468 * unif.c (markra): Same.
469 * variable.c (scm_markvar): Same.
470 * ports.c (scm_markstream): Same.
471 (void_port_ptob): Specify zero for our marking function.
472 * debug.c (debugobjsmob): Same.
473 * dynwind.c (guardsmob): Same.
474 * filesys.c (dir_smob): Same.
475 * fluids.c (fluid_smob): Same.
476 * fports.c (scm_fptob, scm_pipob): Same.
477 * mallocs.c (mallocsmob): Same.
478 * regex-posix.c (regex_t_smob): Same.
479 * smob.c (freecell, flob, bigob): Same.
480 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
481 * throw.c (jbsmob, lazy_catch_funs): Same.
483 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
485 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
486 scm_copy_tree on code in order not to let memoized code to leak
487 out. Thus, scm_copy_tree needs to copy vectors as well since
488 quasiquote can introduce evaluated code also inside vector
491 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
493 * eval.c (scm_copy_tree): Removed ability to copy vectors.
495 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
496 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
499 * unif.c: Say that ivect and uvect are of type signed and unsigned
500 long instead of int in commentary so that it correctly describes
503 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
505 * stime.c: Removed declaration of strptime. (It should be
506 declared by the system headers. If it turns out that some systems
507 don't, we'll handle that then.) (Thanks to Greg Troxel.)
509 * stime.h: Renamed TIMEH --> STIMEH
511 * backtrace.c (scm_display_error, scm_display_backtrace): In order
512 to increase portability, don't use structure assignment.
513 (Thanks to Nicolas Neuss.)
515 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
517 (finalize_fd_sets): Added empty statement after last case label.
518 (Thanks to Nicolas Neuss.)
520 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
523 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
525 * init.c, readline.c: OK, I won't have these readline.x bug
526 reports anymore. We've had them since April. The current reason
527 is a completely unintelligible failure of totoro.red-bean.com to
528 do the test for rl_getc_function in libreadline correctly. This
529 kludge overrides the test if we're on totoro so that the snapshot
530 generation process can work.
532 * readline.c: Define a strdup replacement if not existent on system.
534 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
536 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
537 This change makes scm_make_vector R5RS compatible. We cannot keep
538 the third argument since people want to be able to deduce the form
539 of the C function call only by looking at R5RS. (At the same time
540 we have removed some unnecessary complexity!)
542 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
543 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
544 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
545 argument in call to scm_make_vector.
547 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
549 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
550 This macro is useful in applications.
552 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
554 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
555 (scm_parse_path, scm_search_path): New Scheme level procedures.
557 * load.h (scm_internal_parse_path, scm_parse_path,
558 scm_search_path): Declared.
560 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
562 * filesys.c (dirname, basename): New procedures.
564 * init.c (scm_boot_guile_1): Removed condition around
567 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
568 new data type (guards) for representation of C level guards and
569 data on the wind chain.
570 (scm_internal_dynamic_wind): New function.
572 * dynwind.h: Declare scm_internal_dynamic_wind.
574 * root.h (scm_root_state): Added scm_cur_loadp.
576 * root.c (mark_root): Added comment about cur_loadp.
578 * load.c: #include "dynwind.h";
579 (scm_primitive_load): Use scm_inner_dynamic_wind to update
582 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
584 * ports.c (current-load-port): New procedure.
586 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
588 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
589 not a tty, return #f.
591 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
592 to Julian Satchell and Roland Kaufmann.)
594 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
595 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
597 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
599 * debug.h, debug.c (scm_start_stack): New function. Implements
600 the guts of old scm_m_start_stack.
602 * debug.c (scm_m_start_stack): Use scm_start_stack.
604 * init.c (scm_start_stack, scm_restart_stack): Renamed to
605 start_stack and restart_stack. (These have static scope.)
607 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
609 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
610 readline functions to come in release 2.3. (Thanks to Chet
612 (handle_errors): Use the above functions.
614 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
616 * readline.c: Improvements for readline support: Handle errors
617 better; Implement before-read-hook.
619 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
621 * init.c (scm_boot_guile_1), readline.c: Test for
622 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
623 assure that we have version >= 2.1.)
625 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
627 * readline.c (scm_readline): Defer interrupts while we're calling
630 * readline.c (scm_add_history): Bugfix: Do strdup before giving
631 away the string to add_history.
632 (completion_function): Do completion for readline. (Thanks to
634 (scm_filename_completion_function): New procedure: Filename
636 (current_input_getc): New function. Use this one instead of
637 standard getc from readline.
639 * throw.c, throw.h (scm_handle_by_throw): New function: This
640 handler throws errors to next handler on the dynwind chain.
642 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
644 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
647 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
649 * procprop.c (scm_i_procedure_arity): New function. Returns arity
651 (scm_procedure_properties): Modified to return arity together with
653 (scm_procedure_property): Added the read-only property `arity'.
654 (scm_set_procedure_property_x): It is an error to set the `arity'
657 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
658 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
660 * procprop.h (scm_sym_arity): New symbol.
662 * objects.c (scm_set_object_procedure_x): New procedure: Use this
663 to set the dispatch procedure of an operator or entity object.
665 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
666 Made procedure slots read-only.
668 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
669 scm_tcs_cons_gloc case in zero args switch; Fixed args
670 construction for operators in scm_tcs_cons_gloc case in two args
673 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
675 * fluids.c: Removed use of assert.h (in order to avoid
678 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
680 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
682 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
683 change makes the evaluator safer at the cost of evaluation speed.
684 It handles the case when the user has added a non-immediate
685 improper end of the application form, e.g., `(+ 0 . x)'.
686 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
687 minimize the extra cost as much as possible. The new code is
688 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
689 problem with structs planted directly in the code (e.g. by a
690 macro). This no longer causes segmentation fault. (Thanks to
693 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
694 arg `proc' in order to be able to throw errors; New argument
697 * Removed extra #include "debug.h"
699 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
701 * scmsigs.c: Declare usleep as returning void on some systems.
702 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
705 * coop.c (usleep): Return void on some systems.
707 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
709 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
711 * coop.c: Changed return type of usleep to int.
713 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
714 isn't found in the OS.
716 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
717 isn't enabled. (Thought that I had made this change ages ago...)
719 * iselect.c: Declare bzero if not defined by OS.
721 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
723 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
724 condition. (Thanks to John Tobey.)
726 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
727 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
730 * __scm.h: Start the long-term project of moving to POSIX threads.
731 Phase 1: Classification of all critical sections.
732 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
733 for A sections. (See comments in __scm.h for details.)
735 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
736 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
738 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
740 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
741 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
742 (libpath.h, versiondat.h): Replaced dependency on Makefile with
743 dependencies on $(srcdir)/Makefile.in
744 $(top_builddir)/config.status in order to avoid circularity.
746 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
747 from argc if argc was 0 initially.
749 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
750 in generation of libpath.h.
752 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
754 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
755 libguile from 2 to 3.
757 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
759 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
761 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
763 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
764 scm_set_port_column_x, scm_port_filename,
765 scm_set_port_filename_x): Removed optional arguments. Added
766 proper argument checking.
768 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
769 stack size in machine words.
771 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
772 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
773 to Ole Myren Röhne.)
775 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
777 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
778 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
780 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
783 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
784 procedure apply: Copy argument lists before pushing them unto the
785 environment so that the environment won't get mutated due to
786 manipulation of procedure arguments. This should perhaps be
787 regarded as a temporary solution until someone finds a more
788 efficient one. (Thanks to Maciej Stachowiak.)
790 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
792 * script.c (scm_compile_shell_switches): Use "guile" as default
793 zero arg if argc is NULL.
795 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
797 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
798 is zero. (Thanks to Dirk Herrmann.)
800 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
802 * ports.c (scm_add_to_port_table): First line is now line 0
803 (was 1). (Interface changed according to suggestion by Per
806 * backtrace.c (display_header): Add 1 to line and column numbers
807 when presenting them to the user.
809 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
810 from debug.c --> eval.c
812 * eval.h, eval.c (scm_eval_options_interface): New options
814 (SCM_EVAL_STACK): New option: Size of newly created stacks,
815 i.e. stacks for new threads.
817 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
819 * eval.c (unsafe_setjmp): Removed with #if 0.
821 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
824 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
825 to avoid compiler warnings.
827 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
829 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
831 * throw.c (handler_message): Print message on current error port
832 instead of default error port. (Thanks to Maciej Stachowiak.)
834 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
836 * ports.c (scm_add_to_port_table): allocate in units of
837 struct scm_port_table *, not struct scm_port_table.
838 * posix.c (scm_close_pipe): remove the port from the port table
840 Thanks to Rob Engle for both fixes.
842 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
844 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
845 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
847 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
849 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
851 * backtrace.c (display_error_body, display_backtrace_body),
852 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
853 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
854 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
855 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
858 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
859 don't receive the jmpbuf arg anylonger.
860 (scm_catch): Don't accept a #f tag.
861 (scm_throw): Check that key is a symbol.
862 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
864 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
866 * async.c (async_pending): Removed declaration.
868 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
870 * dynwind.c (scm_wind_chain): New debug function.
872 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
873 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
874 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
875 extra layer of functions around the body and handler of a thread.
876 This extra layer makes sure that the handler is called in the
877 dynamic context of the surround (= empty dynwind list), but under
878 the *dynamic root* of the body. We can not use the dynamic root
879 of the surround since that root belongs to another thread => stack
880 is not handled correctly. It may seem ugly to use this extra
881 layer, but the extra cost in terms of execution time is really
882 negligible compared to the total amount of time required to create
883 a thread, and it would reduce maintainability to duplicate the
884 crucial and complicated steps performed by cwdr.
886 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
887 (SCM_ALLOW_INTS): Added thread switching code before interrupts
888 get re-enabled. The important effect of this is that interrupts
889 are blocked during thread switching so that thread data structures
890 don't risk getting messed up by an unfortunate signal.
891 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
892 seems to do more aggressive optimization which actually move
893 instructions around in these macros in a fatal way. Therefore:
894 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
895 just superstitious...)
896 (SCM_TICK): Maybe do a context switch and take care of asyncs.
897 This macro should be used instead of SCM_ASYNC_TICK since the
898 latter doesn't do context switches any more.
900 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
901 instead of SCM_ASYNC_TICK.
903 * coop.c, iselect.c: Since thread switches are now performed with
904 interrupts masked, we can't use the old mechanism of delivering
905 signals immediately when they arrive. Signals must instead be
906 delivered when the asyncs run *after* the end of the critical
907 section in scm_internal_select. But this also means after context
908 switch so that the signal will be delivered to a different thread.
909 To avoid this, I have changed the protocol of
910 coop_wait_for_runnable_thread and friends so that they are allowed
911 to return the original thread. So, if a signal arrives during
912 scm_internal_select, we won't any longer be forced do a context
913 switch, but can remain in the same thread and deliver the signal
916 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
917 scm_asyncs_pending and made it global.
919 * iselect.c: Small fixes.
921 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
922 coop_condition_variable_init, coop_condition_variable_wait,
923 coop_condition_variable_signal): Changed return type from `void'
924 to `int'. This is to adhere closer to the pthreads interface.
925 This, in turn, is part of an attempt to provide C versions of the
926 mutex and condition variable primitives which can be part of a
927 frontend to COOP or pthreads.
929 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
930 coop_condition_variable_destroy): New functions.
932 * coop-threads.c (scm_wait_condition_variable): Use
933 coop_condition_variable_wait_mutex.
935 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
936 Definitions moved to coop-defs.h.
938 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
939 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
940 scm_cond_destroy): New C interface to mutecis and cond vars.
942 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
944 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
946 * iselect.c: Now several threads can wait on the same file
947 descriptor. The behaviour is compatible with OS select: All
948 threads waiting for the fd return with the same status.
950 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
952 * coop-threads.c, threads.h (scm_spawn_thread): New function.
953 Can spawn a thread from application C code.
955 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
957 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
958 gh_doubles2scm): New functions.
960 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
962 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
963 commented-out version of gh_eval_str()
965 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
967 * socket.c (scm_bind): free soka after use.
969 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
971 * stime.c (tzvar): new variable.
972 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
973 avoid memory leaks when allocating.
975 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
977 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
980 * gc.c, tags.h: Doc fixes.
982 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
984 * eval.c (macro-eval!): Removed. This function was a design bug.
985 It allowed memoized code to leak out to the scheme level. Most
986 things that you could do with `macro-eval!' can be done with
989 1997-12-20 Tim Pierce <twp@skepsis.com>
991 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
992 scm_fgets now depends on ftell(3) to know how many bytes were
995 1997-12-15 Tim Pierce <twp@skepsis.com>
997 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
998 dealing with strings.
1000 1997-12-13 Tim Pierce <twp@skepsis.com>
1002 Make %read-line more suitable for implementing read-line efficiently.
1003 * ioext.c (scm_read_line): Strip the terminating newline from a
1004 string, and return a cons of the string and its terminator.
1006 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
1007 of the string that is read is stored in this memory location.
1008 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
1009 * genio.c, genio.h (scm_do_read_line): Update caller.
1010 * ports.h (scm_ptobfuns): Update typedef.
1011 * fports.c (scm_fptob, scm_pipob): Update struct.
1013 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1015 * filesys.c (set_element): Return file descriptor.
1016 (fill_select_type): Return the highest file descriptor.
1017 (scm_select): Tell select about the highest file descriptor. On
1018 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
1019 Therefore the extra overhead for calculating the maximum fd seems
1020 to be more than compensated. Is this correct? In any case,
1021 scm_internal_select will be much faster with this info.
1022 (scm_select, fill_select_type, set_element): Don't accept any kind
1023 of object in the file descriptor list or vector.
1025 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1027 * iselect.c (finalize_fd_sets): Bugfix.
1029 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1031 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1032 when using scm_internal_select (since we might switch to another
1035 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1037 * simpos.c (scm_system): always define: use sysmissing if not
1038 available. Check for HAVE_SYSTEM instead of _Windows (does
1039 Windows lack system or does it have an unusable one?).
1040 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1041 Let the argument be optional: if not supplied, call system(NULL).
1043 * ports.c (scm_close_port): relax the type check from OPPORTP to
1044 PORTP; closing a closed port is allowed.
1046 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1048 * fports.c (scm_fgets): Return if the last char in a chunk is
1049 newline. When fgets returns a string whose length is `size-1', it
1050 is ambiguous whether a whole line was retrieved, so we must check
1051 explicitly whether a line terminator is present.
1053 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1055 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
1056 before taking the CDR. (Thanks to Harald Meland.)
1058 * filesys.c (scm_stat): Slightly optimized.
1060 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
1062 * ports.c (scm_close_port): Make sure the port is open before
1065 * guile-snarf.in: Pass args through to gcc in a way that preserves

1070 * stacks.c (scm_frame_procedure): Reverse the logic in the return
1071 statement. (Thanks to Doug Evans for pointing this out.)
1073 1997-12-01 Tim Pierce <twp@skepsis.com>
1075 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
1077 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
1079 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
1080 errno macro expansion of this field name. (errno is a C
1081 preprocessor macro on some systems.)

1098 * root.h (scm_root_state): Removed the_last_stack_var.
1100 * throw.c: Added #include "fluids.h"

1103 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
1104 --> the_last_stack_fluid.
1106 * backtrace.c: Added #include "fluids.h"
1107 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
1108 (scm_backtrace): `the-last-stack' is now a fluid.
1110 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
1111 after scm_init_fluids.
1113 1997-11-28 Tim Pierce <twp@skepsis.com>
1115 * iselect.c: #ifdef USE_THREADS around thread-related includes.
1117 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
1118 DLSYM_ADDS_USCORE to decide whether to add an underscore.
1120 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1122 * iselect.c (coop_next_runnable_thread,
1123 coop_wait_for_runnable_thread): Disable interrupts so that no
1124 async is executed before a potential error_revive.
1125 (scm_internal_select): Disable interrupts during the parts of the
1126 code which manipulate the sleep queue and the file descriptors.

1133 scm_internal_select.
1134 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1135 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1136 replacement in iselect.c.
1137 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1138 coop_join): If GUILE_ISELECT enabled, use
1139 coop_wait_for_runnable_thread instead of
1140 coop_next_runnable_thread.
1141 (usleep, sleep): New replacements for system functions if
1142 GUILE_ISELECT is enabled.
1144 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1146 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1148 * filesys.c: Added #include "iselect.h". Moved FD-macros to
1149 iselect.h. Implement Scheme level `select' using
1150 scm_internal_select. (See NEWS.)
1152 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1154 * init.c: Call scm_init_iselect.
1156 * iselect.h, iselect.c: New files. Implements

1159 1997-11-27 Tim Pierce <twp@skepsis.com>
1161 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1162 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1163 and scm_must_free, since ultimately the string returned will be copied
1164 by scm_makfrom0str anyway. Also, read any characters that may have
1165 been pushed onto the port with scm_ungetc.
1166 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1167 * ioext.c (scm_read_line): Free string after Guilifying it.

1172 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
1174 * gh.h: Safely wrap prototypes for c++ usage.
1176 1997-11-25 Mark Galassi <rosalia@cygnus.com>
1178 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
1179 gh_repl (argc, argv).
1181 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1183 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1184 and to invoke scm_shell().
1185 (gh_launch_pad): took out the loading of boot-9.scm from here,
1186 since it is probably best to let the user control that. In fact,
1187 gh_repl() now invokes scm_shell() which does that.
1189 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1191 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()

1213 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1214 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1216 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1218 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1219 configure.in was changed).
1221 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
1223 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1224 * Makefile.in: Regenerated.
1226 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1228 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1229 OPORT is an `open' port, not an output port.
1231 * filesys.c (scm_close, set_element, get_element, scm_chown,
1232 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use

1238 scm_close_all_ports_except, scm_set_current_output_port,
1239 scm_set_current_error_port): Likewise
1240 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1241 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):

1253 Minor problems with substring-related tag changes.
1254 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1255 exactly what we want to leave in to detect substrings.
1256 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1257 * tags.h: Fix diagrams and comments describing the S tag bit;
1258 remove vestigial remarks about the D tag bit.

1260 * strings.c: Formatting tweaks.
1262 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment

1275 * scmconfig.h.in: Regenerated, after change to ../configure.
1277 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1279 * gh.h: gh_vector_set -> gh_vector_set_x
1281 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1283 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1284 with the ! -> _x mapping when going from Scheme to C.
1286 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1288 * gh.h (gh_reverse):

1307 complete the picture R4RS functions that should be mirrored in the
1310 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1312 * tags.h (scm_tc7_substring): Changed the comment and code to
1313 conform with the changes below. Folks! We have suddenly two new
1314 free tc7 codes!!! Jummy, jummy!

1378 * gh_test_c.c (c_vector_test): some improvements on the vector
1381 * gh.h (gh_vector): this used to exist but do the wrong thing.
1382 Now it (almost) does the right thing, though it takes a list
1383 instead of the individual arguments. I need to see how it could
1385 (gh_list_to_vector): added this function as a macro. Corresponds
1386 to Scheme's (list->vector ...).

1394 (gh_make_vector): this used to be (stupidly) called gh_vector().
1395 This is the right name, since it does the same thing as the Scheme

1432 printing: Also output hex code of vtable so that type identity
1433 will be indicated as well.
1434 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1435 Removed struct_printer_var; Removed struct-vtable-offset;
1436 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1437 vtable-offset-user): New constants.

1445 transformers. (They are always: exp env.); Bugfix: Unmemoize
1446 transformer source with correct environment.

1455 (cwdr_handler): New function.
1456 (scm_internal_cwdr): New function to perform the function of cwdr
1457 but take args that are more useful to C code. Also, the handler
1458 is now invoked *outside* of the new dynamic root, like the docs
1459 say. We no longer have to catch absolutely all errors, the caller
1460 is responsible for using a handler that does not throw, if he
1462 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1463 * root.h (scm_internal_cwdr): New prototype.
1465 Even more but risky streamlining:
1467 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1468 allocation of the jumpbuf of a root continuation. The changes
1469 below are controlled by it. They are now deactivated.
1470 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1471 the JMPBUF of the scm_rootcont to NULL before returning.
1473 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1474 when they are non-NULL.

1492 (scm_free_print_state): Set `revealed' field to false.
1493 (scm_iprin1): Call user supplied closure printer with
1494 scm_printer_apply. Print in the traditional way when there isn't
1495 one or when it returns #f.
1496 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1497 Accept a port/print-state pair in addition to just a port.
1498 (scm_prin1): Don't return the print_state to the pool when it has
1500 (scm_printer_apply): Set `revealed' field of print_state to true.
1501 (scm_init_print): Set scm_print_state_vtable.
1502 (print_state_fluid, print_state_fluid_num): Removed.

1511 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1513 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1514 was looping endlessly.
1516 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1518 * strports.c (scm_eval_string): Don't close the port.
1520 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1521 former returns a nice normal integer. (Thanks to Daniel
1524 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1526 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1527 makefile variable as a build parameter called LIBS. The
1528 build-guile program will use this, for the time being.
1529 * Makefile.in: Regenerated.
1531 Thanks to Shiro Kawai:
1532 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1533 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1536 * Makefile.in: Regenerated with automake 1.2a.
1538 * script.c (scm_compile_shell_switches): If we hit the -c or --
1539 arguments, don't set the car of (command-line) to scm_usage_name,
1540 the prettified name of the guile executable; give it the full
1541 path, the way shells usually handle $0.
1543 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1545 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1546 Scheme-level name `array-map' and renamed `serial-array-map' to
1547 `serial-array-map!'.
1549 * backtrace.c: Introduced exception handlers which now enclose
1550 `display-error' and `display-backtrace' so that error reporting
1551 won't get into infinite loops if an error occurs during displaying
1552 of the error. This can very easily happen with user supplied
1553 print call-back routines.
1555 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1557 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1558 the names `serial-array-map' and `array-map' should be removed.)
1560 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1562 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1563 Added #include "objects.h"
1565 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1566 Add #include "feature.h".
1568 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1569 (modinclude_HEADERS): Added objects.h.
1571 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1572 This test is needed at many places in the code and should be
1573 abstracted. (Motivated by the need of this test in libguiletk.)
1575 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1576 (scm_eval_string), load.c (scm_primitive_load,
1577 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1578 Use SCM_EOF_OBJECT_P.
1580 * eval.c (scm_init_eval): Add feature `delay'.
1582 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1584 * scmhob.h: Removed.
1586 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1588 * list.h (SCM_LISTn): New macros. Make list creation in C code
1589 prettier. The idea comes from STk.
1591 * sequences.h, sequences.c, append.h, append.c: Removed. These
1592 files implemented non-R4RS operations which would encourage
1593 non-portable programming style and less easy-to-read code.
1595 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1598 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1599 sequences.h, #include append.h.
1601 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1604 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1606 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1608 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1610 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1612 * eval.c: Added #include "objects.h"
1614 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1617 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1618 adjacent smob numbers.
1620 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1622 * procprop.h: Added declaration of scm_i_inner_name.
1624 * gsubr.c: New global symbol scm_i_inner_name.
1626 * debug.c (scm_procedure_name): Try procedure property
1627 `inner-name' if `name' fails.
1629 * print.c (scm_iprin1): Use scm_macro_name.
1631 * eval.c (scm_m_define): Give names to macros as well; Only the
1632 first top-level definition gives a procedure/macro a name.
1633 Otherwise confusing names can turn up in backtraces.
1634 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1635 `name'; Give names to macros as well.
1637 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1638 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1641 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1643 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
1645 (prinmacro): Removed. The code has been moved/merged into print.c
1646 in order to decrease code redundancy. We want macros to print in
1647 a way equivalent to procedures, and it would be silly to duplicate
1648 the required code. (We don't want to maintain two places.)
1649 (macrosmob): Print field is now a NULL pointer.
1651 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1652 scm_macro_transformer): New prototypes.
1653 (scm_tc16_macro): Declared.
1655 * * print.c (scm_iprin1): Added code for printing of macros. Macros
1656 are now printed in a way equivalent to procedures.
1658 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1660 * procs.h (scm_closure_p): Added declaration.
1662 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1664 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
1665 Shouldn't pass "heap" as the subr name.
1667 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1669 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
1670 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
1671 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1672 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1673 SCM_BOOL_T. Any non-false value is true.
1675 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1677 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1678 scm_gensym): Added prototypes.
1680 * symbols.c (scm_gensym): New function. This will speed up
1681 certain types of applications (such as macro systems) which
1682 generate lots of symbols.
1684 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1686 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
1688 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
1690 * unif.c (scm_shap2ra): tighten the checking of the array dimension
1691 specifier, since (2) or (2 . 3) would cause SEGV.
1692 (scm_transpose_array): more argument checking fixes.
1694 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1696 * Makefile.in: Regenerated.
1698 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1700 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
1702 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1704 * error.c, error.h (scm_error_callback): Removed (see NEWS).
1706 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
1708 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
1709 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
1712 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
1713 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1714 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
1715 scm_array_p, scm_array_rank, scm_array_dimensions,
1716 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
1717 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
1718 scm_array_prototype): Added case scm_tc7_wvect.
1720 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
1722 * errno.h: prototype for scm_strerror.
1723 * error.c (scm_strerror): new procedure.
1725 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1727 * list.c (scm_list_append_x): Allow non-pair as last argument.
1728 This is consistent with the R4RS append and is probably the
1729 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1731 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1733 * stime.h: prototype for scm_times.
1734 * stime.c (scm_times): new procedure.
1735 * ioext.c (scm_fseek): if the first argument is a file descriptor
1737 (scm_ftell): if the first argument is a file descriptor call lseek
1739 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
1740 * filesys.c (scm_chmod): if the first argument is a file descriptor,
1742 (scm_chown): if the first argument is a port or file descriptor,
1744 (scm_truncate_file): new procedure.
1745 Add DEFER/ALLOW INTS to a few other procedures.
1746 (scm_fsync): new procedure.
1747 (scm_open_fdes): new procedure.
1748 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
1750 (scm_fcntl): the first argument can now be a file descriptor. The
1751 third argument is now optional.
1753 * posix.c (scm_execl, scm_execlp): make the filename argument
1754 compulsory, since omitting it causes SEGV.
1755 (scm_sync): return unspecified instead of #f.
1756 (scm_execle): new procedure.
1757 (environ_list_to_c): new procedure.
1758 (scm_environ): use environ_list_to_c. disable interrupts.
1759 (scm_convert_exec_args): take pos and subr arguments and
1760 improve error checking.
1762 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1764 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1765 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1766 argument to SCM_ASSERT. Furthermore, the name of the function
1767 should be passed as first argument when signalling
1768 SCM_WNA. (Thanks to Thomas Morgan)
1770 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1771 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1772 dispatches on the number of actual args has a default case
1773 reporting an internal error. This is a vestige from a version
1774 that mallocated a SCM vector to hold the arguments. In the
1775 current version this check is too late: if it ever happens we will
1776 have already overstepped the bounds of the array.
1778 Also, the patch [...] adds a check for too many actual arguments."
1780 mdj: Removed check for "internal programming error".
1782 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1784 * gh_io.c (gh_write): New function.
1786 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
1787 throw.c (scm_internal_stack_catch): New sibling to the other catch
1788 functions. Code moved from gh_eval.c.
1789 throw.h: Added header.
1790 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
1791 scm_internal_stack_catch.
1793 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1795 * ioext.h: fix up prototypes.
1796 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
1797 Scheme name is now dup->fdes.
1798 (scm_dup_to_fdes): make the second argument optional and
1799 fold in the functionality of scm_primitive_dup.
1800 (scm_primitive_dup): deleted.
1802 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1804 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
1805 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
1806 ultrix are defined. Use setvbuf instead of setbuf.
1807 (scm_setvbuf): new procedure.
1808 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
1809 (scm_setfileno): moved from ioext.c.
1810 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
1811 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
1813 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1815 * fluids.c (scm_fluid_p): New function.
1816 * fluids.h (scm_fluid_p): New prototype.

1820 * print.c (scm_iprin1): Enter printed structures into the print
1821 state as nested data while they are printed.
1822 (print_state_fluid, print_state_fluid_num): New variables.
1823 (scm_init_print): Initialize them.
1824 (scm_iprin): If print_state_fluid carries a print_state, use that
1825 instead of creating a new one.
1826 (scm_printer_apply, apply_stub, struct apply_data): New
1827 definitions to help with calling printer functions written in
1829 * print.h (scm_printer_apply): New prototype.
1831 * struct.c (scm_print_struct): Use scm_printer_apply to call the
1832 user defined struct printer.
1834 * dynwind.c (scm_dowinds): Handle fluids on the wind list.
1835 * fluids.h (scm_internal_with_fluids, scm_with_fluids,

1840 Fri Jul 25 12:05:46 1997 Marius Vollmer <mvo@zagadka.ping.de>
1842 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
1843 SCM_ASSERT: arg comes before pos.
1845 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1847 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
1848 to a list of length zero correctly.
1850 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1852 Supply an `fgets' method for port objects to do fast line i/o.
1853 * ioext.c (scm_read_line): New function.
1854 * genio.c (scm_gen_read_line): New function.
1855 * fports.c (scm_fgets): New function.
1856 (scm_fptob, scm_pipob): Add scm_fgets method.

1864 Mon Jul 21 04:03:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1866 * ioext.h: removed scm_duplicate_port prototype.
1868 * ioext.c (scm_primitive_dup2): return the new file descriptor
1869 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
1871 (scm_fdopen): bug fix: don't try to make port unbuffered until its
1872 stream has been set.
1873 (scm_duplicate_port): deleted, there's now an implementation in
1875 (scm_primitive_dup2): do nothing if newfd == oldfd.
1877 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
1879 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
1882 * ioext.h: new prototypes.
1883 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
1885 * fluids.c (next_fluid_num): don't do
1886 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
1888 * ports.h: prototypes too.
1889 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
1891 * fports.h: prototype too.
1892 * fports.c (scm_evict_ports): moved from ioext.c.
1894 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
1896 * ports.c (scm_close_port): return a boolean instead of unspecified.
1897 throw an error if an error other than EBADF occurs.
1899 * filesys.h: scm_close prototype.
1900 * filesys.c (scm_close): new procedure, can close file descriptors
1901 and ports (scsh compatible).
1903 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
1906 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
1908 * fluids.c, fluid.h: New files.
1909 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
1910 (modinclude_HEADERS): Added "fluids.h"
1912 * init.c: Include "fluids.h". (scm_boot_guile_1): Added call to
1913 scm_init_fluids to initialize the fluid machine.
1914 (scm_start_stack): Initialize the fluids of the first root with
1915 scm_make_initial_fluids.
1917 * root.h: Added "fluids" member to scm_root_state.
1918 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
1919 (scm_make_root): Call scm_copy_fluids to make fluid bindings
1920 unique for the new root when it has a parent.
1922 * smob.h: Include "libguile/print.h" to make scm_print_state
1925 * dynl.c (free_dynl_obj): New function to free the dynamic object
1926 data. (dynl_smob): Use it.
1927 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
1928 the dynamic object data below the linking of the object to avoid
1929 memory leak when the linking code throws an error. Now the code
1930 leaks a whole dynamically linked library when must_malloc throws,
1931 but that should be much less likely.
1933 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
1935 Changes to compile under gnu-win32, from Marcus Daniels:
1936 * stime.c (tzset): If tzset isn't provided, make it a NOP.
1937 (scm_localtime): Change SCM_EOF to SCM_EOL.
1938 (scm_mktime): Likewise.
1939 * socket.c: Don't include sys/un.h unless autoconf tells
1940 us Unix domain sockets are available.
1941 (scm_fill_sockaddr): Ignore Unix domain code.
1942 (scm_addr_vector): Likewise.
1943 (scm_init_addr_buffer): Likewise.
1944 (scm_socketpair): Don't include unless socketpair was

1947 * scmsigs.c (scm_pause): Don't include unless pause was found
1949 * posix.c (scm_getgroups): Don't include unless support function
1950 was found during autoconf (in this case, getgroups).
1951 (scm_setpwent): For setpwent.
1952 (scm_setegid): For setegid.
1953 * net_db.c (scm_inet_netof): Don't include unless support
1954 function was found during autoconf (in this case, inet_netof).
1955 (scm_lnaof): For inet_lnaof.
1956 (scm_inet_makeaddr): For inet_makeaddr.
1957 (scm_getnet): For getnetent, getnetbyname, getnetbyaddr.

1966 Thu Jul 10 00:22:24 1997 Jim Blandy <jimb@floss.red-bean.com>
1968 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
1969 scm_misc_error, not SCM_EOF.
1971 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
1972 arguments for formatting the error message, not SCM_BOOL_F. I
1973 think this is left over from the (eq? '() #f) days.
1975 * read.c (recsexpr): Give this a dummy definition if
1976 DEBUG_EXTENSIONS isn't #defined.
1978 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
1980 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
1983 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>

1988 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
1990 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
1991 alloca.lo will be included in @LIBLOBJS@. Something better than
1992 this should be possible.
1993 * Makefile.in: Regenerated.
1995 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1997 * simpos.h: prototype for scm_primitive_exit.
1998 * simpos.c (scm_primitive_exit): new procedure, terminates the
1999 process without unwinding the stack.
2001 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
2003 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
2004 argument and logior its components together, so the user doesn't
2005 have to do this explicitly. Also, if regexp/basic is supplied, then
2006 turn off REG_EXTENDED.
2007 (scm_init_regex_posix): New regexp/basic symbol.
2008 (REG_BASIC): #define this if it is not already present.
2010 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2012 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
2013 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
2014 (CLEANFILES): New target, clean versiondat.h, libpath.h.
2015 (DISTCLEANFILES): New target, clean *.x.
2016 * Makefile.in: Regenerated.

2020 * script.c (scm_compile_shell_switches): Add 1997 to copyright
2021 years in usage message.
2023 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
2024 * Makefile.in: Regenerated.
2026 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
2027 flag; I don't think we support it.
2028 (scm_make_regexp): Make sure the user doesn't pass the
2031 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
2033 (scm_init_regex_posix): Define constants for the REG_mumble flags;
2034 name them according to the SCSH convention: regexp/mumble.
2036 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
2038 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
2040 * Makefile.am (libpath.h): Include the values of all the standard
2041 Makefile directory variables. Print a message, but don't print
2043 (versiondat.h): Print a message, but don't print all the commands.
2044 * load.c: #include "alist.h".
2045 (init_build_info): New function.
2046 (scm_init_load): Call it.
2047 * Makefile.in: Regenerated.
2049 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
2051 * root.c: Establish a reliable catch-all handler for the new root.
2052 After all the Scheme handler function might signal an error too,
2053 and we don't want to lose that.
2054 (cwdr_inner_body): Renamed from cwdr_body.
2055 (cwdr_outer_body): New function, to establish the user's handler,
2056 and pass control to cwdr_inner_body.
2057 (cwdr): Establish the reliable catch-all handler here, and pass
2058 control to cwdr_outer_body.
2059 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
2060 the user's handler through to cwdr_outer_body.
2061 * throw.c (scm_handle_by_message): Move guts into....
2062 (handler_message): New static function.
2063 (scm_handle_by_message_noexit): New function.
2064 * throw.h (scm_handle_by_message_noexit): New prototype.
2066 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
2067 across this. Only works on GCC. Otherwise, we hope for the best.
2068 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2069 the feeling that real thread systems will not need this...
2071 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2073 Try to detect when people are using one version of libguile and a
2074 different version of ice-9. People have been skewing things and
2075 sending in bug reports.
2076 * Makefile.am (versiondat.h): New file to generate.
2077 * version.c: #include "versiondat.h", to get version info.
2078 (scm_libguile_config_stamp): New function.
2079 * script.c: #include "version.h".
2080 (scm_compile_switches): Call scm_version to get version number.
2081 * scmconfig.h.in, Makefile.in: Regenerated.
2082 * Makefile.in: Regenerated.
2084 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
2085 primitive definitions under their Scheme names.
2087 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2088 1:2. Helps avoid confusion between installed and uninstalled libs.
2090 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2093 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2094 backslash from definition; this should be used like: GDB_INTERFACE;
2096 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2098 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
2099 new port unbuffered until its stream has been set.
2101 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2103 * ports.h: new prototype.
2104 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
2106 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
2108 Make things compile neatly under Sun's C compiler.
2109 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
2110 * extchrs.c (xmbtowc): Make the second arg a normal char, not
2111 unsigned, because that's what the ANSI function takes.
2112 * extchrs.h (xmbtowc): Corresponding change to prototype.
2113 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2115 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2116 argument plain char *.
2117 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2119 * tag.c (scm_tag): Remove unreachable statement.
2120 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2121 top of the word, it should be unsigned.
2123 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2124 is defined, to avoid warnings; it's only used in the
2125 conflict-checking code. Which might go away anyway.
2126 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2127 conditionals; put the label definition in an #if too, to stifle
2130 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2131 ChangeLog-threads in the distribution.
2132 * Makefile.in: Regenerated.
2134 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2136 * guile-snarf.in: Changed regexp to support CPPs that insert
2137 whitespace between lexical tokens (which munges the `%%%' snarf
2140 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2142 * load.c (scm_init_load_path): Append $(datadir)/guile to
2143 %load-path, so modules do not have to be installed in Guile's
2144 current version directory.
2146 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2148 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2149 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2150 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2151 call the sysdep functions with deferred ints.
2152 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2153 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2154 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2157 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2160 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2162 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2164 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2166 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2169 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2171 * eval.c (scm_lookupcar1): New procedure to cope with a race
2172 condition during lookup (when using threads).
2173 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2174 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2177 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2179 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2180 supplied. (Change from Tim Pierce.)
2182 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2184 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2185 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2186 default and not `()'. `#f' is the canonical non-value in Scheme,
2189 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2191 * struct.c (struct_printer): New variable that holds a handle on
2192 the Scheme variable *struct-printer*. This variable can be set by
2193 Scheme code to override the printing of structures.
2194 (scm_print_struct): If struct_printer is set, call it. If it is
2195 not set, or returns #f, print the structure in the old fashion.
2196 Include "eval.h" for scm_apply.
2198 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2200 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2201 scm_struct_i_n_words to get the number of fields, not
2202 -scm_struct_n_extra_words.
2204 On the route to fancier struct printing:
2205 * struct.c (scm_print_struct): New function to print a structure.
2206 Include "genio.h" to support it. This function doesn't do
2207 anything interesting right now, but I think it should be here
2209 * struct.h: Include "print.h" and add prototype for
2211 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2212 print structures ourself.
2214 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2216 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2217 before applying the handler in case it doesn't return.
2219 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2221 * scmsigs.h, async.h: updated.
2223 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2226 * posix.c (scm_uname): interpret only negative values as an error.
2227 Solaris normally returns a positive value.
2229 * script.c (scm_compile_shell_switches): if we are not going into
2230 an interactive repl, set scm_mask_ints to zero so that asyncs can
2233 * simpos.c (scm_system): don't ignore/unignore signals around
2236 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2239 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2240 done in boot-9.scm instead.
2242 * scmsigs.c, async.c: Major rewriting of signal handling code.
2243 (scm_sigaction): new procedure.
2244 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2246 (scm_raise): return unspecified, throw error on failure.
2248 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2250 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2251 feature, to help boot-9.scm decide whether to import the regex
2254 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2256 * eval.c: Include scmconfig.h at the beginning of the file so that
2257 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2260 * regex-posix.c: #include "_scm.h" before conditionally #including
2261 <regex.h>; the former defines HAVE_REGCOMP.
2263 * regex-posix.c: #include <regex.h> conditionally, so the file is
2264 CPP'able (for dependency scanning) even on systems that don't have
2267 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2269 Add new R4RS-compliant syntax for keywords.
2270 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2271 regardless of the setting of the `keywords' read option.
2272 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2273 can be re-read no matter what the setting of the `keywords' read
2276 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2278 Add support for POSIX regular expressions.
2280 * regex-posix.c, regex-posix.h: New files. (Some code
2281 is taken liberally from rx/rgx.c in the old Guile dist.)
2283 * init.c: Include regex-posix.h.
2284 (scm_boot_guile_1): Call scm_init_regex_posix.
2286 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2287 Add regex-posix.[ch] sources.
2288 * Makefile.in: Regenerated.
2290 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2291 to do this automatically? It didn't for me, bleh.)
2293 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2295 * fports.c (print_pipe_port): New function.
2296 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2297 latter doesn't even take the right arguments.
2299 * Makefile.am: Increment shared lib revision number. I think
2300 sometimes the uninstalled Guile finds the installed shared lib;
2301 Gord says doing this might help. As things turned out, I can't
2302 say whether it does.
2303 * Makefile.in: Regenerated.
2305 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2306 passing it as the closure argument to scm_boot_guile. (Bill
2309 * ports.c (print_void_port, putc_void_port, puts_void_port,
2310 write_void_port, flush_void_port, getc_void_port, close_void_port,
2311 noop0): Use ANSI prototypes instead of K&R declarations, so the
2312 initialization of void_port_ptob gets aggressively type-checked.
2313 Fix arguments of print_void_port and write_void_port. (Bill

2347 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2349 * script.c (scm_find_executable): Use prototype-style definition
2350 here; apparently it's not quite right to have const in a prototype
2351 and then use a K&R declaration. I wonder if stuff like this will
2352 go away if we compile with -Wrequire-prototypes, or whatever that
2353 is... (Bernard URBAN)
2355 * scmhob.h: New text from Bernard URBAN.
2357 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2359 * script.c: Don't #define const on hpux. Configure takes care of
2360 this. (Thanks to Larry Schwimmer.)
2362 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2363 decide whether to #include <unistd.h>, instead of listing a bunch
2364 of systems. Don't #include stdio twice. Removed dyked-out
2365 definition of scm_find_impl_file.
2367 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2369 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2370 library version info to 1:0.
2371 * Makefile.in: Regenerated.

2377 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2378 throw.c: Update copyright years; these files have been worked on
2379 significantly in 1997, but only had copyright years for 1996.
2380 Also, change name of copyright holder on some from Mikael
2381 Djurfeldt to Free Software Foundation; he has signed papers
2382 assigning the changes to the FSF.
2384 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2385 reason not to give the user the option.
2387 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2388 Return #f on end-of-file when scanning table (i.e. when called
2389 with no arguments). Try to catch errors, when we can.
2390 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2392 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2393 external declarations. These are useful.
2395 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2397 * posix.c: don't include <sys/select.h> or define macros for
2398 select, since they were not used in this file.
2400 * filesys.c (scm_select): make the fifth parameter microseconds,
2401 not milliseconds. let the fourth parameter be either a real value
2402 or an integer or #f. The first, second and third arguments can
2403 now be vectors: the type of the corresponding return set will be
2405 (set_element, get_element): new static procedures.
2407 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2409 * strports.c (scm_eval_string): New function.
2410 (scm_eval_0str): Trivially re-implemented in terms of
2412 * strports.h (scm_eval_string): New extern decl.
2414 * net_db.c (h_errno): Add extern decl for this.
2416 * fports.c (local_pclose): New function.
2417 (scm_pipob): Use it in the initializer here.
2420 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2421 Use a meaningful error message when signalling an error. For
2422 this, scm_gethost must check h_errno rather than errno.
2424 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2426 * Makefile.in: Regenerated, using automake-1.1p.
2428 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2430 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2431 not SCM_UNSPECIFIED.
2433 * script.c (scm_compile_shell_switches): don't append (quit) if
2435 (scm_shell): call scm_exit_status and exit on the result of the
2438 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2440 Ensure that shared substrings are handled properly when passed to
2441 a system call or other foreign function. Many thanks to Tim
2443 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2444 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2445 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2446 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

2448 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
2449 (scm_display_error_message): use RO macros when strings may be RO.
2450 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
2451 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
2452 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
2453 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
2454 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
2455 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
2456 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
2457 scm_strftime), vports.c (scm_make_soft_port): use
2458 SCM_COERCE_SUBSTR to make sure shared substrings are

2463 * error.c (scm_error): Add newline to error message.
2465 * init.c (scm_init_standard_ports): Doc fix.
2467 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2469 * dynl-shl.c: Completely replaced with new code from Bernard
2472 * script.c (scm_ice_9_already_loaded): New variable.
2473 (scm_compile_shell_switches): Use it.
2475 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2477 * filesys.c (scm_input_waiting_p): add missing third argument to
2480 * stime.c (scm_localtime): copy the result of localtime before
2481 calling gmtime in case they share a buffer.
2482 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2485 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2487 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2489 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2491 * Makefile.am (check-local): New target, which causes 'make check'
2492 to run gh_test_c and gh_test_repl, with some trivial input.
2493 * Makefile.in: Rgnrtd.
2495 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2497 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2500 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2502 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2503 sure how this was supposed to work.
2504 (scm_async_click): don't send SCM_TICK_SIGNAL.
2505 (scm_init_async): don't initialize %tick-thunk.
2507 * the following change doesn't affect the Scheme interface:
2508 gc-thunk is called at the end of garbage collection. however it's
2509 no longer implemented by pretending it's a signal.
2511 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2512 system async corresponding to scm_gc_thunk.
2513 * async.h: declare scm_gc_async.
2514 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2515 gc-thunk directly, instead of going through a signal handler.
2516 (scm_gc_async): new variable, points to the GC system-async.
2517 (scm_init_async): save the GC async as scm_gc_async instead
2518 of using system_signal_asyncs.
2519 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2521 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2523 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2524 Don't screw up if we're interrupted.
2525 * Makefile.in: Regeneradet.
2527 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2529 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2531 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2532 we're not using AM_INIT_GUILE_MODULE any more.
2533 * Makefile.in: Reneregated.
2535 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2537 Functions for finding variable bindings, grace à Tim Pierce.
2538 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2539 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2541 Get 'make dist' to work again.
2542 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2543 * Makefile.in: Regenerated, like a surry without a fringe on top.
2545 Changes for reduced Guile distribution: one configure script,
2547 * configure.in, configure: Removed.
2548 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2549 real configure script lives.
2550 * Makefile.in, scmconfig.h.in: Regenerated.
2552 * init.c: #include "script.h", to get prototype for script.c's
2555 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2557 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2558 scm_must_malloc, not raw malloc.
2560 * script.c (scm_compile_shell_switches): Dyke out debugging output
2563 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2565 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2567 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2568 system has them. Hope this is safe. Previously
2569 sys/timeb.h was included if HAVE_FTIME was defined or if
2570 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2571 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2573 * ioext.c (scm_setfileno): add missing third argument to
2574 scm_misc_error call.
2576 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2578 * eq.c (scm_equal_p): Correctly compare strings of different
2579 varieties. (Thanks to Tim Pierce.)
2581 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2583 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2584 #! block comment must occur on a line all by itself.
2586 Move most of the guts of shell command processing into libguile,
2587 so guile.c can be very small (and eventuallly auto-generated. (I
2588 mean, generated mechanically, not self-generated. Hmm.))
2589 * guile.c, script.c, script.h: New source files.
2590 * init.c (scm_boot_guile_1): Call scm_init_script.
2591 * libguile.h: #include "script.h".
2592 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2593 targets, for new executable.
2594 (libguile_la_SOURCES): Mention script.c.
2595 (modinclude_HEADERS): Add script.h.
2596 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2597 not dynamic linking is enabled. This is because we're generating
2598 executables now. Move CY_AC_WITH_THREADS call after those, so the
2599 values of cy_cv_threads_libs captures the libs chosen above.
2600 * Makefile.in, configure, aclocal.m4: Regenerated.
2602 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2603 We don't maintain this interface any more, and it just confuses
2606 * alloca.c: #include <scmconfig.h>, not <config.h>.
2607 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2608 it'll get included in disties.
2610 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2612 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2613 be distributed, because they confuse people.
2614 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2616 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2618 * configure.in: check for presence of gethostent (not present on
2619 OpenBSD by default).
2620 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2621 * configure, scmconfig.h.in: Regenerated.
2623 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2625 * backtrace.c (scm_backtrace): Split message string across
2626 newlines properly. GCC is more tolerant of this than other
2629 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
2631 Merge threads directory into libguile.
2632 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
2633 threads.h: New source files.

2635 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2637 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2638 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2639 coop-threads.c.cygnus, coop-threads.h.cygnus.
2640 * configure.in: If we're using threads, include threads.o in
2642 * _scm.h, libguile.h: threads.h lives in this directory now.
2643 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2644 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2645 currently used, but brought along for information's sake.
2646 * ChangeLog-threads: log from old 'threads' directory.
2647 * Makefile.in, configure: Rebuilt.
2649 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2651 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2654 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2656 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2658 Merge GH interface library into libguile.
2659 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
2660 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2661 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2662 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2664 (EXTRA_libguile_la_SOURCES): ... here.
2665 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2666 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2667 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2668 New variables, describing how to build the gh test programs.
2669 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2670 build the test programs, and we probably should have been linking
2671 libguile.la against them all along, to support AIX shared libs.
2672 Add cflags for threads to CFLAGS; add libs for threads to new
2673 variable THREAD_LIBS, used in Makefile.am.
2674 * ChangeLog-gh: log from old `gh' subdirectory.
2675 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2677 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2679 * acconfig.h: Undo change of Apr 9; including the definition of
2680 PACKAGE in the guile headers conflicts with applications' own
2682 * scmconfig.h.in: Regenerated.
2684 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

2690 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
2691 when PROC is receiving no arguments.
2693 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2695 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2696 have S_IFSOCK. This is the case under Ultrix.
2698 * posix.c (scm_status_exit_val, scm_status_exit_val,
2699 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2700 Ultrix versions of WIFSTOPPED, etc., which assume that their
2701 arguments are lvalues (hmm).
2703 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2705 * eval.c: Doc fixes.
2707 * throw.c: Doc fixes; rearranged.
2709 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
2711 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
2713 * acconfig.h: Added entry for PACKAGE.
2714 * scmconfig.h.in: Regenerated.
2716 Changes to work with automake-1.1n, which has better libtool support.
2717 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2718 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
2720 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
2722 * Makefile.in: Rebuild.
2724 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2726 * stime.c (scm_mktime): take an optional zone argument.
2727 (scm_localtime): check putenv return value.
2728 (scm_strftime, scm_strptime): moved from posix.c. move #include
2730 stime.h, posix.h: update prototypes.
2731 (bdtime2c, setzone, restorezone): new static procedures.
2732 (scm_mktime, scm_strftime): use them.
2733 (scm_strftime): don't call mktime before strftime. Use
2734 filltime for return value.
2735 (filltime): convert NULL zname to #f.
2736 (scm_strptime): return a count of characters consumed, not
2737 the remaining string.
2739 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2741 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
2742 (scm_mktime): likewise.
2744 Uncomment localtime and mktime.
2746 * configure.in: add AC_STRUCT_TIMEZONE.
2748 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2750 * stime.c (scm_init_stime): don't define ticks/sec.
2751 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2752 return value problem and is still portable.)
2754 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2756 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2757 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2758 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2759 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2760 cpp_err_symbols.c): Corresponding changes.
2761 * Makefile.in: Regenerated.
2763 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2765 * posix.c (scm_putenv): don't check HAVE_PUTENV.
2766 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
2767 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
2768 * putenv.c: new file, from sh-utils 1.12.
2770 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2771 since allocation isn't for Scheme objects.
2772 (scm_putenv): copy strings before placing in the environment.
2774 * stime.c (scm_current_time): throw an error if time returns -1,
2775 instead of returning #f.
2776 (scm_get_internal_real_time, scm_get_internal_real_time): use
2777 scm_long2num for return value instead of SCM_MAKINUM.
2779 * stime.h: prototypes updated.
2781 * stime.c (scm_time_in_msec): apparently unused, deleted.
2783 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2785 * configure.in: check for gettimeofday.
2787 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2788 which may be more usefully portable than a gettimeofday interface.
2790 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2792 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
2794 * Makefile.in: Regenerated.
2796 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2798 * stime.c (filltime): recovered static procedure.
2799 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
2802 * posix.h: add prototype for scm_close_pipe, remove prototypes for
2803 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2805 * posix.c (scm_mknod): split the mode argument into type and perms
2806 arguments, like the extra fields returned by stat.
2808 * fports.c (scm_pipob): set the close, free and print procedures.
2809 (scm_close_pipe): new procedure.
2811 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2812 define them in boot-9.scm
2814 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2816 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
2817 wan't defined. Don't include fd.h.
2819 * Previously fd.h was regenerated whenever configure was run,
2820 forcing a couple of files to be recompiled.
2822 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
2823 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
2824 Check for _fileno as well as _file.
2826 * ioext.c: don't fd.h.
2827 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
2830 * Change the stratigy for getting information about errno
2831 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
2832 generating lists of symbols during the build process, which will
2833 not always work, include comprehensive lists in the distribution.
2834 To help keep the lists up to date, the "check_signals" and
2835 "check_errnos" make targets can be used.
2837 * configure.in: don't check for a command to extract errno codes.
2838 * Makefile.am: update file lists, remove errnos.list and errnos.c
2839 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
2840 check_errnos targets.
2841 (CLEANFILES): remove errnos.c and errnos.list, add
2842 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
2843 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
2844 * errnos.default: deleted.
2845 * cpp_signal.c: new file.
2846 * cpp_errno.c: renamed from errnos_get.c.
2847 * cpp_err_symbols, cpp_sig_symbols: new files.
2848 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
2849 * error.c (scm_init_error): #include cpp_err_symbols instead of
2851 * posix.c (scm_init_posix): don't intern signal symbols. #include
2854 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
2856 * strop.c (scm_i_index): allow the lower bound to be equal to the
2857 length of the string, so a null string doesn't always give an error.
2859 * posix.h: new prototypes.
2860 * posix.c (scm_status_exit_val, scm_status_term_sig,
2861 scm_status_stop_sig): new functions, as in scsh. They break down
2862 process status values as returned by waitpid.
2864 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
2866 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
2867 configure doesn't know about it.
2869 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2871 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
2873 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
2874 which defines C variables with global linkage.
2876 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2878 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
2881 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
2883 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
2884 has time to check why this doesn't work well with continuations.
2886 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
2888 * Fix shell syntax error; some shells won't tolerate
2889 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
2891 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2893 * posix.c (scm_uname): throw an error if uname fails instead
2896 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
2898 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
2901 * async.c (scm_ints_disabled): definition moved from error.c.
2903 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2905 * acconfig.h: Removed PACKAGE.
2907 * scmconfig.h.in: Regenerated.
2909 * snarf.h: g++ says it's non-portable not to specify the first
2910 argument in a varargs declaration. I introduced the first
2911 argument by using preprocessor conditionals.
2913 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
2915 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
2916 (scm_freopen): use RO string macros for filename and modes.
2917 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
2919 * posix.c (scm_getgrgid): simplify conversion of name to C string.
2920 (scm_mknod): use RO string macros for path.
2922 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
2923 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
2925 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2926 use SCM_ROSTRINGP and SCM_ROCHARS.
2928 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2930 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
2933 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
2934 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
2935 support for byte vectors.
2937 * print.c (scm_iprin1): Limit number of vector elements printed
2938 according to pstate->length.
2940 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2942 * backtrace.c (scm_display_error_message): don't segv if message
2945 * error.h: prototype for scm_error_scm.
2947 * error.c (scm_error_scm): new procedure, reimplements scm-error
2948 in C and uses scm_error.
2950 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2952 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
2953 pointer to the Scheme variable read-hash-procedures and intern it
2954 in scm_init_read. Modify scm_read_hash_extend and
2955 scm_get_hash_procedure to use the pointer.
2957 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2959 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
2960 (SCM_KEYWORD_STYLE): defined.
2962 * read.c (scm_read_opts): add a keywords option. This isn't a
2963 boolean option, in case someone wants to add support for DSSSL
2965 Setup scm_keyword_prefix symbol.
2966 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
2968 I've left keyword support disabled by default, since it doesn't
2969 seem to break the module system and it gives R4RS standard behaviour.
2970 It can be reactivated with (read-set! keywords 'prefix).
2972 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2974 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
2975 before constructing arbiter.
2977 * eval.c (scm_m_define): Bugfix: Check that the object is a
2978 closure before setting the procedure property!
2980 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
2982 * ports.c: Removed `ungetc-char-ready?'.
2984 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
2986 * read.c (scm_init_read): intitialise scm_read_hash_procedures
2987 (idea from Mikael: make it a pair so scm_permanent object only
2989 (scm_read_hash_extend): don't call scm_permanent_object.
2990 (ideas from Mikael): if chr is already in the list, replace its
2991 procedure instead of appending it again. If proc is #f, remove
2993 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
2995 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
2997 * gdbint.c (gdb_read): update scm_lreadr usage.
2999 * load.h: update prototypes.
3001 * load.c (scm_primitive_load, scm_read_and_eval_x,
3002 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
3004 * read.h: add prototype for scm_read_hash_extend. Change args for
3007 * read.c (scm_read_hash_procedures): new variable.
3008 (scm_read_hash_extend): new procedure.
3009 (scm_get_hash_procedure): new procedure.
3010 (scm_lreadr): use scm_get_hash_procedure instead of an argument
3011 for extended # processing.
3012 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
3013 scm_read_token): remove case_i, sharp arguments. Change callers.
3015 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
3017 * read.h (SCM_N_READ_OPTIONS): increase to 3.
3018 (SCM_CASE_INSENSITIVE_P): define.
3020 * read.c: add case-insensitive option to scm_read_opts.
3021 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
3022 to determine whether to convert symbol case.
3023 (default_case_i): definition removed.
3024 * read.c (scm_read_token): if case_i, downcase ic before doing
3027 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3029 * configure.in: Added configuration option `guile-debug'.
3030 Configure with --enable-guile-debug if you want a bunch of extra
3031 functions used for debugging when developing Guile.
3033 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3035 * procs.c (make-cclo): New undocumented debugging procedure: Make
3036 compiled closure with internal procedure PROC and length LENGTH.
3037 Only compiled if GUILE_DEBUG is defined.
3039 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3041 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3043 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3045 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3046 with 3 or more args internally to the evaluator.
3048 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3050 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3051 with 3 or more args internally to the evaluator. This is mainly
3052 because we don't want to pass entry and exit points of the
3053 debug support twice, but it also seems to increase the speed of
3054 the evaluator for such calls (e. g. (+ 1 2 3)).
3056 * backtrace.c (scm_display_application): New procedure:
3057 display-application; Set fancy printing parameters individually
3058 for different types of display (backtrace, error, application).
3059 (These should of course be customizable!)
3061 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3062 clear the CHECK-flags.
3064 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3066 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3068 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3070 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3071 from pairs with a GLOC in the car.
3073 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3074 otherwise `symbol-hash' will behave badly.
3075 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3076 we get segmentation fault!
3078 * symbols.c: Added #include "weaks.h". New functions:
3079 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3080 moved to an extraneous library when we split libguile.)
3082 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3084 * filesys.c (scm_stat): stat now takes fport arguments too as
3085 documented in the manual.
3087 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3089 * debug.c (scm_single_step): Bugfix: Call continuation with
3090 scm_call_continuation instead of throwing to it.
3092 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3094 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3095 argument wasn't declared to be optional.
3097 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3099 * stime.c (scm_init_stime): Add feature "current-time".
3101 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3103 * throw.h: prototype for scm_exit_status.
3104 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3105 args to derive an exit status. Allows (quit) to work from a
3107 (scm_exit_status): new function.
3110 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3112 * eval.c (scm_deval): Removed some old code.
3113 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3115 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3118 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3121 * procs.c: Introduce the existent C function scm_thunk_p at the
3122 Scheme level as well.
3124 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3126 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3127 used from C to easily lookup the value of a symbol in the current
3130 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3132 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3133 scm_init_unif in this file. This will also fix a previous problem
3136 * configure.in: Added AM_MAINTAINER_MODE
3138 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3140 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3143 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3145 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3146 source files that are not always included in libguile but should
3147 have their dependencies calculated by automake. This variable is
3148 recognized by automake, no further magic is needed.
3149 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3150 to deal exclusively with *.lo files, as it seems. The *.o files
3151 are built automatically when the corresponding *.lo file gets
3154 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3156 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3159 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3161 * unif.c (scm_array_set_x): minor change to argument error checking.
3163 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3165 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3166 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3167 They should only be included in the library at configure.in's
3169 (libguile_la_LDADD): Include the appropriate .lo files here.
3170 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3171 so we know when to build them (and their .lo bretheren).
3172 * configure.in (LIBLOBJS): New substituted variable. We let
3173 configure decide which .o files to include in LIBOBJS, and then
3174 put the corresponding list of .lo files in LIBLOBJS. The latter
3175 is what we pass to libtool.
3176 * Makefile.in, configure: regenerated.
3178 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3180 * symbols.c (scm_sysintern0): New function. Contains the core of
3181 old scm_sysintern but doesn't take a second value argument.
3182 (scm_sysintern): Now uses scm_sysintern0.
3183 (scm_sysintern_no_module_lookup): Renamed to
3184 scm_sysintern0_no_module_lookup and doesn't take a second value
3185 argument any longer.
3187 * symbols.h (scm_sysintern0: Added declaration.
3189 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3190 scm_sysintern when interning option keys. Otherwise we risk
3191 destroying the values of already interned variables.
3193 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3194 scheme-level boolean (use SCM_NFALSEP).
3196 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3198 (scm_backtrace): New function. (C version of old function from
3199 boot-9.scm) Motivation: Make it possible to display backtraces
3200 without depending on boot-9.scm. (I'm uncertain if this
3201 motivation is good enough...)
3203 * root.h (scm_root_state): Add member the_last_stack_var.
3204 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3206 * root.c (mark_root): Mark scm_the_last_stack_var.
3208 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3211 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3213 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3214 1. mark_lazy_catch didn't mark the smob.
3215 2. Both functions above have standard variants:
3216 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3217 free_lazy_catch --> scm_free0.
3219 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3221 * throw.c (scm_internal_lazy_catch): New function.
3222 (scm_lazy_catch): Rewritten to use it.
3223 (scm_ithrow): Handle the new lazy catch representation.
3224 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3225 that doesn't have a jmpbuf is a lazy catch clause.
3226 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3227 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3228 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3230 (scm_init_throw): Register the new lazy-catch smob type.
3231 * throw.h (scm_internal_lazy_catch): decl for new function.
3233 * throw.c (scm_internal_catch): Doc fixes.
3235 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3236 configure.in. Including this might cause problems if applications
3237 that link against libguile include their own copies of alloca, but
3238 if they're using autoconf, they should be adding libguile to LIBS
3239 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3240 the copy in libguile, and things will be okay. (I think.)
3242 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3244 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3246 strop.h: move prototypes too.
3248 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3250 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3253 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3254 etc. I deleted them from filesys.c long ago, but didn't
3255 notice they were here too (although ineffective since
3256 sys/stat.h wasn't included).
3258 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3260 * eval.c: Don't define alloca in GCC case. gcc will automatically
3261 use __builtin_alloca if appropriate.
3263 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3265 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3266 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3267 that values of automatic variables are preserved. See comments
3268 for safe_setjmp for details.
3270 Change from Thomas Morgan:
3271 * variable.c: Include eq.h.
3272 (var_equal): New function.
3273 (variable_smob): Use var_equal as the discriminator for variables.
3275 * throw.c (s_throw): Remove extraneous declaration.
3277 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3278 * eval.c: Add necessary CPP cruft to support that.
3279 * configure, Makefile.in, scmconfig.h.in: regenerated.
3281 Change from Thomas Morgan:
3282 * procprop.c (scm_procedure_properties): Convert the Scheme
3283 boolean returned by scm_procedure_p into a C boolean before using
3284 it as a condition for SCM_ASSERT.
3285 (scm_procedure_property): Likewise.
3287 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3288 indications of Unixness.
3291 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3293 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3295 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3297 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3298 "unknown # object" error messages.
3300 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3301 (scm_i_index) and declare it static. Add a 'direction' argument
3302 to indicate what way the search should go.
3303 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3305 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3306 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3308 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3310 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3312 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3313 to avoid clash with various scsh forks.
3315 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3317 The following two changes (ramap.c, throw.c) are motivated by the
3318 apparent unportability of forward declarations of static arrays of
3319 the form `static foo bar[];'.
3321 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3322 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3324 * throw.c (scm_throw): Moved above scm_ithrow.
3326 * options.h: Removed the extern declarations of scm_yes_sym and
3327 scm_no_sym since these are static.
3329 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3331 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3333 * Makefile.am: remove AWK=@AWK@.
3334 Add a rule for generating errnos.list.
3335 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3337 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3338 don't extract errnos, just set a variable (avoids the
3339 need to recompile error.c just because configure is run.)
3341 * unif.h: update prototypes.
3342 * unif.c (scm_uniform_array_read,write): change the offset and
3343 length arguments to start and end, for consistency.
3345 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3347 * ioext.h: update prototypes.
3348 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3349 scm_read_line_x, it's a more general procedure using an
3350 interface from scsh. read-line and read-line! are now defined
3352 Note that the new read-line trims the terminator
3353 by default, previously it was appended to the returned string. An
3354 optional argument specifies how to process the terminator (scsh
3355 compatible). For the old behaviour: (read-line port 'concat).
3356 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3357 returns a pair, but is converted to multiple values if the scsh
3360 socket.h: update prototypes.
3361 * socket.c (scm_recvfrom): for consistency with other procedures,
3362 take start and end as separate optional arguments.
3363 (scm_recv, scm_recvfrom): don't allow the second argument
3364 to be a size, only a buffer. Change the scheme names to
3365 recv! and recvfrom!. Don't return the buffer.
3367 * ioext.h, posix.h: move prototypes too.
3368 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3369 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3370 "read.h" and "unif.h".
3371 * ioext.c: include "chars.h"
3373 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3375 * dynl.c: The dynamic linking and module registration functions
3376 are now defined even when dynamic linking is not available for the
3377 host system. Some of their functionality can be done without
3378 dynamic linking; when it's really needed, they throw errors.
3380 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3382 * configure.in: Only define DYNAMIC_LINKING when one of the system
3383 dependent functions is detected.
3384 * dynl.c (scm_dynamic_func): New function to get the address of a
3385 function in a dynamic object.
3386 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3387 produced by scm_dynamic_func as the thing to call.
3389 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3391 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3392 (scm_register_module_xxx, scm_registered_modules,
3393 scm_clear_registered_modules): New functions.
3395 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3397 * symbols.c (scm_sysintern): Renamed to
3398 scm_sysintern_no_module_lookup.
3399 (scm_sysintern): New function to take the place of the old
3400 scm_sysintern. It uses the current toplevel lookup closure to give
3401 the symbol its value. This is a temporary hack to put packages
3402 like gtcltk into their own module.
3403 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3404 us whether `scm_top_level_lookup_closure_var' has been initialized
3406 * eval.c (scm_init_eval): Set it.
3408 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3410 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3411 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3413 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3415 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3416 scm_sys_dup): deleted: FD capability will be added to other
3418 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3419 scm_fd_free, fd_smob, scm_intern_fd.
3420 (scm_open): renamed from scm_sys_open. Return a port instead of
3421 an FD object. Make the mode argument optional.
3422 (scm_sys_create): deleted, it's just a special case of open.
3423 (scm_init_filesys): move interning of constants O_CREAT etc.,
3424 here (were previously using SCM_CONST_LONG macro).
3425 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3427 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3428 include "fports.h" and <stdio.h>
3429 (scm_stat, scm_select): don't support FD objects.
3431 * error.h: adjust scm_syserror_msg prototype.
3432 * error.c (scm_syserror_msg): take an extra argument for errno.
3433 Using the global value didn't always work, since it could be
3434 reset by procedure calls in the message or args arguments.
3436 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3437 I don't understand why the check was there (and what about the
3440 * strop.c (scm_string_copy): allow shared substrings to be copied.
3442 * unif.h: corresponding change to prototypes.
3443 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3444 recognize two new optional arguments: offset and length. Allow
3445 the port argument to be an integer (file descriptor, for scsh).
3446 Include <unistd.h> for "read" prototype.
3448 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3450 * socket.c: don't include filesys.h.
3452 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3454 * Makefile.am: add AWK=@AWK@ (?)
3456 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3458 Add a rule to generate errnos.c from errnos.
3459 * error.c (scm_init_error): include errnos.c.
3460 * errnos_cnvt.awk: new file, converts the list of errno codes to
3462 * errnos_get.c: new file.
3463 * errnos.default: new file, contains errnos to try if they can't
3464 be extracted from errno.h.
3465 * configure.in: if using GCC, try and extract errno codes from
3469 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3471 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3472 * Makefile.am: Made libguile into a libtool library.
3473 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3474 Set libtool_libs to indicate that libguile is a libtool library.
3475 See guile/ChangeLog for details.
3476 * .cvsignore: ignore "*.lo", the libtool library objects.
3478 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3480 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3481 use htons in getservbyport argument.
3483 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3485 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3486 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3489 * objprop.c (scm_object_property): No need to take the CDR of the
3490 value returned by scm_object_properties, since Aug 20 change.
3492 * configure.in: When checking for struct linger, #include
3493 <sys/types.h> as well as <sys/socket.h>. I've never known
3494 <sys/types.h> to cause any portability problems, and Solaris's
3495 <sys/socket.h> needs it.
3496 * configure: Rebuilt.
3498 I think the Sun compiler has chosen a perverse way to interpret
3499 ANSI declarations combined with K&R definitions. We'll
3500 appease it a little bit. But when it invades France, we fight.
3501 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3502 * print.h (scm_iprlist): Here too.
3503 * numbers.c (scm_divbigdig): Change definition to match
3504 declaration in numbers.h.
3505 * unif.c (scm_makflo): Change definition to match declaration in
3508 * init.c (scm_boot_guile): Don't return the value of
3509 scm_boot_guile_1. This function doesn't return a value;
3510 scm_boot_guile_1 doesn't return a value (or return at all).
3512 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3515 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3516 compile. I have a feeling this function is a bad idea anyway ---
3517 one should always test for features, not systems.
3519 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3520 semicolons. Only pure luck kept this from being noticed earlier.
3522 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3524 * socket.c (scm_recvfrom): Added missing semicolon.
3526 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3528 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3529 the buffer and start and end positions for scsh networking
3532 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3534 * configure.in: Revert previous change to this file; the problem
3535 is due to transient automake weirdness.
3536 * configure: Rebuilt.
3538 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3539 PLUGIN/guile.libs. configure generates the latter from the former.
3540 * Makefile.in: Rebuilt.
3542 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3543 need this if we install scripts, like guile-snarf.
3544 * configure: Rebuilt.
3546 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3548 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3550 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3552 * socket.c (scm_addr_vector): fix faulty scm_listify.
3554 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3556 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3557 style block comment is no longer considered an error.
3559 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3561 * PLUGIN/guile.libs.in: New file.
3562 * PLUGIN/guile.libs: Removed from repository.
3563 * configure.in: Create PLUGIN/guile.libs from
3564 PLUGIN/guile.libs.in. This is for including additonal libraries
3565 needed for dynamic linking.
3566 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3567 instead of PLUGIN/guile.libs.
3569 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3571 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3573 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3574 occurrences of the given element from the list, not just the
3575 first. This is how the Emacs Lisp functions behave, how the
3576 analogous Common Lisp functions behave, and (I believe) how the
3577 older Maclisp functions worked. I realize that this change may
3578 break code, but it seemed better to break it before the Guile
3581 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3582 Their prototypes were already present in gc.h, but they weren't
3584 (scm_init_storage): Initialize scm_protects.
3585 * root.c (scm_protects): New element of scm_sys_protects.
3587 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3589 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3591 * libguile.h: Added #include "libguile/net_db.h".
3593 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3594 30 change. That file is only meant for communication between the
3595 configuration process and load.c. If code linked against libguile
3596 wants to get at the paths mentioned in libpath.h, it can call
3597 functions declared in load.h.
3599 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3601 * libguile.h: Removed #include "libguile/fdsocket.h"
3603 * net_db.c: Added #include <sys/socket.h>.
3605 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3607 * filesys.c (scm_input_waiting_p): use select in preference to
3608 FIONREAD, since the latter doesn't detect EOF.
3609 Throw error if neither select nor FIONREAD available.
3611 * socket.c (scm_connect): take a port, not a fd object.
3612 (scm_fill_sockaddr): throw an error if fam is not recognised.
3613 (scm_bind): use scm_fill_sockaddr.
3614 (scm_listen): take a port, not a fd object.
3615 (scm_accept): take and return a port. return #f in the car if
3616 address can't be got
3617 (scm_sock_fd_to_port): new procedure.
3618 (scm_socket): use scm_sock_fd_to_port.
3619 (scm_addr_vector): throw error if unrecognised address type.
3620 take an extra argument with the calling procedure name.
3621 (scm_getsockname): take a port. return #f if address can't be got.
3622 (scm_getpeername): take a port. return #f if address can't be got.
3623 (scm_recvfrom): take a port. return #f for address component if can't
3625 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3626 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3628 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3630 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3631 use separate data pointers, to allow them to be designed
3632 independently and reused.
3633 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3634 Renamed from catch_body, catch_handler, and uncaught_throw; made
3636 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3638 (scm_catch): Use the above.
3639 (scm_throw): Don't bother printing a message for an uncaught
3640 throw; we establish a default handler in init.
3641 * throw.h (scm_internal_catch): Prototype updated.
3642 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3644 (struct scm_body_thunk_data): New structure, used as data
3645 argument to scm_body_thunk.
3646 * init.c (struct main_func_closure): New structure, packaging up
3647 the data to pass to the user's main function.
3648 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3649 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3650 scm_internal_catch to establish a catch-all handler, using
3651 scm_handle_by_message. This replaces the special-case code in
3653 (invoke_main_func): Body function for scm_internal_catch; invoke
3654 the user's main function, using the main_func_closure pointer to
3655 decide what to pass it.
3656 * root.c (struct cwdr_body_data): Remove handler_proc member.
3657 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3658 (cwdr_handler): Removed.
3660 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3662 * socket.h (SCM_P): update bind prototype.
3663 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3664 include "feature.h".
3665 (scm_socket): return a port, not a file descriptor object.
3666 include "fports.h" and <unistd.h>
3667 (scm_bind): take a port, not a file descriptor object.
3668 take an extra argument for address args.
3670 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3671 INADDR_NONE, INADDR_LOOPBACK.
3673 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3675 * init.c: include net_db.h and not fdsocket.h.
3676 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3678 * Makefile.am: corresponding changes.
3679 * socket.h: renamed from fdsocket.h, fix names.
3680 * net_db.h: renamed from socket.h, fix names.
3681 * socket.c: renamed from fdsocket.c.
3682 remove _sys from procedure names.
3683 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3684 add "socket" to features list.
3685 * net_db.c: renamed from socket.c.
3686 remove _sys from procedure names.
3687 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3688 add "net-db" to features list.
3689 include "net_db.h". don't include <sys/socket.h> or
3692 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3694 * tags.h (scm_tags): Removed comma at end of last enumerator.
3696 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3698 Don't use GCC extensions to allocate space for debugging frames.
3699 (Here he goes again! Why do we put up with this?!)
3700 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3701 an scm_debug_info structure, not an in-line array of them. Add
3702 'info' member, to say how many vect elements we've used, for eval
3704 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3705 a new variable debug_info_end to mark the end of vect, instead of
3706 the address of the 'info' pointer itself.
3707 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3708 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3709 (SCM_APPLY): Explicitly allocate space for debug.vect.
3710 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3711 * stacks.c: Adjusted for new debug frame structure.
3712 (RELOC_INFO, RELOC_FRAME): New macros.
3713 (stack_depth, read_frames): Use them, and new scm_debug_frame
3714 element 'info', instead of magically knowing that eval frames have
3715 an info pointer sitting after vect.
3716 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3718 (scm_init_stacks): Formatting tweaks.
3720 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3722 Give GCC more control flow information, so it can be sure that
3723 variables aren't used uninitialized.
3724 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3725 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3726 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3727 scm_misc_error): Tell GCC that these functions never return.
3728 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3729 out the field type, call abort if SCM_ASSERT returns, to placate
3731 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3732 scm_wta ever returns. We can't handle this case anyway, and this
3733 gives the optimizer more information.
3734 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3735 scm_wta ever returns.
3737 In some cases, the code is fine, but GCC isn't smart enough to
3738 figure that out; this usually happens when one variable is only
3739 initialized and used when a particular condition holds true, and
3740 we know that condition will never change within a given invocation
3741 of the function. In this case, we simply initialize the variables
3742 to placate the compiler, hopefully to a value which will cause a
3743 crash if it is ever actually used.
3744 * print.c (scm_iprin1): Initialize mw_pos.
3745 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3746 * throw.c (scm_ithrow): Initialize dynpair.
3747 * unif.c (scm_uniform_vector_ref): Initialize cra.
3748 * struct.c (init_struct): Initialize prot.
3749 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3751 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3752 if EXPR contains no expressions.
3754 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3756 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3757 cause an infinite loop (???). So much for the algebraic
3758 equivalency of variable-sized arrays and alloca...
3760 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3762 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3763 a SCM boolean, not a C boolean.
3765 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3767 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3768 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3769 rules for raising scm_mtrigger. Previously, unfortunate but not
3770 unlikely circumstances could result in almost constant invokation
3771 of the gc. Now, this situations should be less likely, but they
3772 are not prevented completely.
3774 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3776 * numbers.c (scm_fuck): Procedure removed; looks like old test
3778 * numbers.h: Prototype removed.
3780 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3782 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3783 array to a pointer, to match my Nov 21 change in eval.c.
3785 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3787 * libguile.h: Added #include "libguile/backtrace.h", #include
3788 "libguile/stacks.h".
3790 * strings.c (scm_string scm_make_string scm_string_ref
3791 scm_string_set_x scm_string_equal_p scm_string_append):
3792 Bugfix according to scm patch from Aubrey Jaffer:
3793 Corrected long-standing
3794 (not (eqv? (integer->char 128)
3795 (string-ref (make-string 1 (integer->char 128)) 0)))
3796 bug found by John Kozak <jk@noontide.demon.co.uk>.
3798 * strports.c, strports.h: Make scm_eval_0str return the value of
3799 the last expression evaluated (previously, it returned void).
3801 * strports.c, strports.h: New function: scm_read_0str. Does what
3804 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3806 * simpos.c (scm_getenv): return #f if string can't be found in the
3807 environment instead of throwing an exception, for compatibility
3808 with numerous other systems.
3810 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3812 * Makefile.am (.c.x): Use guile-snarf.
3813 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
3815 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
3817 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3819 * backtrace.c (scm_display_error_message): Made non-static, and
3820 renamed from display_error_message.
3821 * backtrace.h (scm_display_error_message): Added extern decl.
3822 * throw.c (uncaught_throw): Use it to display the error message.
3824 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
3826 * inet_aton.c: Use #if 0, not #ifdef 0.
3828 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
3830 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
3831 to convert the returned value.
3832 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
3833 the offset argument.
3835 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3837 Add new interface to catch/throw, usable from C as well as
3839 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
3840 (scm_internal_catch): New function, replaces...
3841 (scm_catch_apply): Deleted.
3842 * throw.c (scm_catch_apply): Deleted; replaced with a more general
3843 mechanism which is a bit more code, but can be used nicely from C
3844 and implement the Scheme semantics as well.
3845 (scm_internal_catch): This is the replacement; it's named after
3846 the analogous function in Emacs.
3847 (scm_catch): Reimplemented in terms of the above.
3848 (struct catch_body_data, catch_body, catch_handler): New
3849 functions, used by scm_catch.
3850 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
3851 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
3852 support for new cwdr.
3854 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
3857 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
3859 * acconfig.h: Added DYNAMIC_LINKING symbol.
3860 * configure.in: Add option and checks for dynamic linking.
3861 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
3862 dynl.h: New files for dynamic linking support.
3863 * Makefile.am (libguile_a_SOURCES):
3865 (modinclude_HEADERS): Added "dynl.h".
3866 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
3868 * init.c (scm_boot_guile_1): Call
3869 scm_init_dynamic_linking to initialize dynamic linking support.
3871 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
3873 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
3874 (as we Schemers say). It needs to be global, so that I can tweak
3875 it for the proper operation of unexec.
3876 (scm_boot_guile_1_live): New variable, see above.
3878 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
3880 * guile-snarf.sh: Removed.
3881 * PLUGIN/guile.libs: Added dependency for -lm.
3882 * acinclude.m4: Renamed from aclocal.m4.
3883 * PLUGIN/greet: Removed.
3884 * Makefile.am, aclocal.m4: New files.
3885 * configure.in: Updated for Automake.
3887 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
3889 * eval.c (scm_definedp): Use top_level_lookup_closure_var
3890 and not top_level_lookup_thunk_var.
3892 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
3894 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
3896 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
3898 * eval.c (scm_definedp): Incompatibly changed to be a builtin
3899 Scheme function, instead of syntax. Single argument is now a
3902 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3904 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
3905 scm_ra_divide): Properly terminate statements passed as arguments
3906 to IVDEP macros. (Thanks to Bernard Urban.)
3908 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
3909 with non-constant sizes. (Thanks to Bernard Urban.)
3911 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3913 It's an "eval closure", not an "eval thunk." A thunk is a
3914 function of no arguments.
3915 * root.h (struct scm_root_state): Renamed
3916 top_level_lookup_closure_var from top_level_lookup_thunk_var.
3917 (scm_top_level_lookup_closure_var): Renamed from
3918 scm_top_level_lookup_thunk_var.
3919 * root.c (mark_root): Uses changed.
3920 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
3921 * init.c (scm_start_stack): Uses changed.
3922 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
3923 Change scheme-visible name to *top-level-lookup-closure* from
3924 *top-level-lookup-thunk*.
3926 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
3928 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
3929 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
3931 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
3933 * gc.c (struct scm_heap_seg_data): Doc fixes.
3935 * gc.c (scm_gc_sweep): Empty all segments' freelists before
3936 sweeping. Then, prepend each segment's free cells to its
3937 freelist, rather than wiping out the old value. (Thanks to Marius
3940 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
3941 scm_check_freelist, scm_debug_newcell): New functions and
3942 variables, for debugging freelist problems.
3943 * pairs.h (SCM_NEWCELL): New debugging version added.
3944 * gc.h (scm_debug_newcell): Added extern declaration, used by
3945 debugging version of SCM_NEWCELL.
3947 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3949 On some systems <libc.h> conflicts with <unistd.h>, and should not
3950 be #included at all.
3951 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
3952 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
3953 * configure.in: Call it.
3954 * posix.c, filesys.c: Use its results to decide whether or not to
3956 * configure, scmconfig.h.in: Rebuilt with autoconf and
3959 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
3961 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
3962 pointer to the stdio stream before calling scm_setbuf0, so the
3963 latter will be able to retrieve it. I'm surprised this didn't
3964 segfault earlier. (Thanks to Christopher Lee.)
3966 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3968 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
3971 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3973 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
3974 number of stack narrowing specifier pairs. The first specifier in
3975 a pair controls inner border, the second the outer border. A
3976 number means cut that number of frames, a procedure object means
3977 cut until that object is found in operator position in a frame.
3979 * root.c (cwdr): Bugfix.
3981 * read.c: Recording of positions disabled by default.
3983 * procs.c (scm_closure_p): New function.
3985 * posix.c (scm_tmpnam): New function.
3987 * load.c: Added #include "throw.h".
3988 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
3991 * load.c, load.h (scm_read_and_eval_x): New function.
3993 * eval.c: Renamed debug option "deval" to "debug".
3995 (scm_eval_x): `eval!' is no longer accessible from the scheme
3996 level. Motivation: We can't allow operations which introduce
3997 glocs into the scheme level. Guile's type system can't handle
3998 these as data. Use `eval' or `read-and-eval!' as replacement.
4000 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
4001 SCM_CONSP since this is a macro!; Set vframe.prev to
4002 scm_last_debug_frame instead of 0. In this way we can look
4003 "above" the virtual start stack frame if we wish.
4004 (scm_debug_hang): New function: Useful for debugging Guile in
4005 certain tricky situations. Will probably be removed later...
4007 * debug.h: Changed semantics of debug option "backtrace". This
4008 option now only indicates whether we want automatic backtrace at
4011 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4013 * ports.c: #include "filesys.h"
4014 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
4016 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
4017 Motivation: This is system specific code which is related to file
4018 I/O. It also may use select. Added code by Gary Houston to
4019 detect presence of character in stdio buffers.
4021 * libguile.h: #include "libguile/libpath.h"
4023 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4024 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4025 SCM_SITE_DIR; Install libpath.h among the other include files.
4027 * load.c, load.h (scm_sys_package_data_dir): New function.
4029 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4031 * stacks.h: Bugfix: Don't use tail-array length field as stack
4032 length field! This screwed GC.
4034 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4036 * _scm.h: Added #ifndef around definition of macros min and max.
4038 * __scm.h: Added hooks for threads to plugin to in ints protection
4039 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4040 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4041 the main code in these macros duplicated and spread over multiple
4042 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4043 SCM_THREAD_SWITCHING_CODE.
4045 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4047 * snarf.h: New file.
4048 * guile-snarf.sh: New file.
4049 * Makefile.in (inner_h_files): Added snarf.h
4050 (ancillary, install, uninstall, distclean): Added actions for
4052 (.c.x): Use guile-snarf.
4053 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4054 (gen_c_files): Note that these depend on guile-snarf.
4055 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4056 now in "snarf.h". Added #include "snarf.h" to get them.
4057 * libguile.h: Added #include "snarf.h".
4058 (Patches applied and tweaked by Jim Blandy.)
4060 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4062 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4063 standards suggest against providing prototypes for system
4064 functions. Thanks to Greg Troxel.
4066 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4068 * strports.c (scm_eval_0str): New function.
4069 #include "read.h", to get prototype for scm_read.
4070 * Makefile.in (strports.o): Update dependencies.
4071 * strports.h: New prototype.
4073 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4074 scheme name from "int?" to "integer?". It seems to do the job.
4075 * numbers.h: Rename prototype too.
4076 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4079 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4080 scm_num_eq_p): Rename these according to R4RS conventions: call
4081 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4082 to making libguile R4RS compliant without ice-9...
4084 * load.c (scm_sys_search_load_path): Search for files under all
4085 extensions listed in the %load-extensions variable. If FILENAME
4086 is absolute, return it unchanged, without searching the load path.
4087 (scm_loc_load_extensions): New variable, pointing to
4088 %load-extensions' value cell.
4089 (scm_init_load): Initialize it, and the value it points to.
4090 (scm_primitive_load_path): Improve error reporting.
4092 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4093 of new Scheme variable %load-hook.
4094 (scm_primitive_load): Apply %load-hook to filename.
4096 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4098 * configure.in: add tests for figuring out whether buffered data
4099 is available in a FILE structure, which is needed by char-ready.
4101 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4104 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4105 exceptions using misc_error instead of syserror. It seems a bit
4106 odd to throw an exception if a string can't be found in the
4107 environment, but it's consistent with open-file, stat etc.
4108 (simpos.h): remove sys_ from getenv.
4110 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4111 occurs, throw an error instead of returning errno. Return value
4113 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4115 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4117 * filesys.c (scm_stat2scm): derive file type and permissions from
4118 the stat mode and append them to the returned vector.
4119 There isn't much overhead in doing this and it avoids the need to
4120 work with S_IRUSR et al. in Scheme.
4121 Define symbols scm_sym_regular etc.
4122 (scm_init_filesys): don't intern S_IRUSR etc.
4124 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4125 and s_primitive_load_path.
4127 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4129 * error.h: don't declare error symbols. prototype for scm_misc_error.
4131 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4134 * error.c: use SCM_SYMBOL to set up error keys.
4135 scm_misc_error: new procedure.
4137 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4139 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4140 between `#!' and `!#' is ignored.
4141 (skip_scsh_block_comment): New function.
4143 * feature.c (scm_set_program_arguments): New argument, FIRST.
4144 * feature.h: Update prototype.
4145 * init.c (scm_boot_guile_1): Pass new argument to
4146 scm_set_program_arguments.
4148 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4150 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4151 (scm_boot_guile): Call scm_set_program_arguments here, later than
4152 the old initialization.
4154 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4155 initialization procedure.
4156 - Delete in, out, err arguments; there are other perfectly good
4157 ways to override these when desired.
4158 - Delete result argument; this function shouldn't ever return.
4159 - Rename init_func argument to main_func, for less confusion.
4160 - Delete boot_cmd argument; main_func is more general.
4161 -Add 'closure' argument, to help people pass data to main_func
4162 without resorting to global variables.
4163 - Abort if reentered; don't bother returning an error code.
4164 - Call scm_init_standard_ports to set up the default/current
4165 standard ports; no need to pass them to scm_start_stack.
4166 - Remove code to evaluate the boot_cmd, and start the repl; let
4167 the user do something like that in main_func if they want.
4168 - Remove code to package up a return value; main_func can do any
4170 - Call exit (0), instead of returning.
4171 (scm_start_stack): Don't initialize the I/O ports here; that's
4172 weird. Delete in, out, err arguments. Move guts to
4173 scm_init_standard_ports, scm_stdio_to_port.
4174 (scm_init_standard_ports): New function, to set up current and
4175 default standard ports.
4176 (scm_start_stack, scm_restart_stack): Make these static.
4177 * init.h (scm_boot_guile): Adjust declaration.
4178 (scm_start_stack, scm_restart_stack): Remove externally
4179 visible declarations for these.
4180 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4182 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4183 written out several times in scm_start_stack.
4184 * fports.h: New declaration for the above.
4186 * feature.c (scm_set_program_arguments): New function.
4187 * feature.h: New declaration for the above.
4189 * ports.c: Formatting tweak.
4191 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4193 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4194 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4195 for obtaining the address of a car or cdr field. Motivation:
4196 &SCM_CXR make assumptions about the internal structure of the
4199 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4200 Motivation: see SCM_CXRLOC.
4202 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4203 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4204 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4205 Motivation: Safer use. Some other macros are defined in terms of
4206 these operations. If these are defined using the SCM_SETCXR
4207 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4208 to inefficiency and an <e1> with side-effects could potentially
4209 break. Also, these particular operations are heavily utilized in
4210 the garbage collector. In unoptimized code there will be a
4213 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4214 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4215 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4216 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4217 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4218 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4219 vports.c: Cleaned up use of pairs: Don't make any special
4220 assumptions about the internal structure of selectors and
4221 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4222 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4223 (Among other things, this change makes it easier to build Guile
4224 with certain compilers which have problems with casted lvalues.)
4226 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4228 * stacks.c: Improve selection of relevant stack frames when making
4229 a stack object. Introduce one level of indirection in the stack
4230 object to make it possible to "narrow" to a certain region of the
4231 stack. This facilitates making use of more clever algorithms (not
4232 implemented) for selecting relevant frames and gives a cleaner
4233 design since selection of frames can be done independently of
4234 extraction of frames from the real stack.
4235 (scm_stack_id): Also take #t as argument which means look at
4238 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4239 Turn n_tail into an integer directly representing current number
4240 of frames in stack. Add field tail.
4242 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4244 * debug.c (scm_make_memoized): Made it available at scheme level.
4245 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4246 SCM_NIMP before applying heavier predicates in argument checking.
4247 (scm_local_eval): Also take memoized object as argument.
4249 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4250 aren't created with zero length, but should such a strange
4251 creature suddenly turn up...
4253 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4255 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4256 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4258 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4260 * variable.c (scm_make_variable): Make the name hint optional, as
4262 (anonymous_variable_sym): Renamed from variable_sym. All uses
4265 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4266 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4267 of scm_primitive_load_path was also changed to
4268 "primitive-load-path", from "%try-load-path". Callers changed.
4269 We'd like to respect the convention that a function named
4270 "try-mumble" should behave just like the function called "mumble",
4271 but return #f instead of signalling some error.
4272 * load.h: Rename prototypes.
4274 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4276 * print.c (make_print_state, grow_print_state), print.h: Modified
4277 the print state representation: Don't use a tail array for
4278 recording of circular references. Resizing of the print state
4279 structure invalidates the print state pointer. To avoid passing
4280 around an indirect print state reference to all printing
4281 functions, we instead let the print state reference a resizable
4284 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4286 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4287 Don't crash when passed an improper list terminated by a
4288 non-immediate value.
4290 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4292 Allocate data for structures on an eight-byte boundary, as
4293 required by the tagging system.
4294 * struct.c (alloc_struct): New function.
4295 (scm_make_struct, scm_make_vtable_vtable): Call it.
4296 * struct.h (scm_struct_n_extra_words): Bump to 3.
4297 (scm_struct_i_ptr): New "field".
4298 * gc.c (scm_gc_sweep): When we need to free the data, use the
4299 information stored by alloc_struct to find the beginning of the
4300 block allocated to the structure, so we can free it.
4302 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4304 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4307 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4308 (scm_debug_info): New member: id.
4310 * stacks.c: Stacks are now represented as structs; Stacks have an
4311 id given to them by `start-stack'.
4312 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4314 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4315 Changed stack representation.
4317 * debug.c (scm_procedure_name): Try procedure property `name' for
4318 compiled closures aswell.
4320 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4322 * eval.c: scm_i_name moved to gsubr.c
4323 (scm_m_define): Record names of all kinds of procedure
4324 objects. (Earlier, only closures were recorded.)
4326 * procprop.h: Added declaration of scm_i_name.
4328 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4329 (scm_make_gsubr): Record names of compiled closures.
4331 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4333 * debug.c, debug.h: Removed obsolete code.
4335 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4336 stacks.c: Renamed regs --> scm_contregs.
4338 * print.c (scm_free_print_state): Cleanup print state before
4339 returning it to pool. It is better to do it here than in
4340 scm_prin1 since scm_prin1 is called often.
4342 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4343 s_set_source_property_x): Check that first argument is a pair or a
4346 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4347 scm_i_line, scm_i_column and scm_i_breakpoint global.
4349 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4350 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4353 * debug.h: Added debug object smob declaration and macro
4356 * configure.in: Build with backtrace.o and stacks.o if debug
4359 * Makefile.in: Added entries for new files: backtrace.c,
4360 backtrace.h, stacks.c and stacks.h.
4362 * symbols.c (scm_sym2ovcell): Fixed documentation.
4364 * _scm.h (min, max): Added.
4366 * async.c: Moved `min' macro to _scm.h.
4368 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4369 SCM_BACKTRACE_INDENT.
4371 * eval.c: Added new debug options `maxdepth' and `indent'.
4373 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4375 * print.h: Added selector SCM_PRINT_STATE.
4377 * print.c: New functions: scm_make_print_state,
4378 scm_free_print_state.
4380 * print.h: Added declarations for scm_make_print_state,
4381 scm_free_print_state.
4383 * debug.c (scm_m_start_stack): New acro.
4385 * debug.h: Small cleanup.
4387 * init.c (scm_boot_guile_1): Moved scm_init_debug below

4415 More prototype-related changes from Marius Vollmer:
4416 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4417 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4418 * ports.h (ptobfuns): Added prototypes. This means some casting in
4420 * fports.c: Added casts for initializations, since the functions
4421 are defined to take FILE * as their stream argument, not SCM.
4422 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4423 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4424 to `char *str_data' to conform to prototype.
4426 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4428 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4430 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4432 * stime.c, stime.h: use SCM_P method.
4434 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4436 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4437 be given at least two arguments. Insist that lst's last element
4438 be a list, but don't make any requirements of its predecessors.
4440 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4442 * eval.c (scm_nconc2last): Revert last change; there seems to be
4443 other stuff going on here.
4445 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4447 * eval.c (scm_nconc2last): Make sure that each element of lst
4448 (which is a list of argument lists, except for the tail) is a
4449 proper list, i.e., finite and terminated by '().
4451 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4453 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4456 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4457 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4460 * vectors.c (scm_make_vector): Fill vectors with the undefined
4461 value, to help make Guile Scheme code more portable to other
4464 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4465 * symbols.h, tags.h: Doc fixes.
4467 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4469 * async.c (scm_take_signal): Doc fixes.
4471 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4473 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4474 want to subtract it from the modulus; we just want to leave it
4477 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4479 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4482 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4484 * throw.c (scm_catch_apply): Finished implementation of
4487 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4489 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4491 (scm_init_filesys): set "i/o-extensions" feature.
4494 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4496 * Makefile.in (root.o): Correct dependencies.
4498 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4500 * Makefile.in: Added dependency entry for root.o.
4502 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4503 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4505 * init.c (scm_start_stack): Set initial root continuation number
4508 * procs.c: New function: scm_thunk_p.
4510 * procs.h: Added declarations of scm_thunk_p.
4512 * root.c: Renamed `call-with-new-root' -->
4513 `call-with-dynamic-root'.
4514 (cwdr): Removed allocation of new root state. This should be done
4515 separately by use of scm_make_root.
4516 (scm_apply_with_dynamic_root): New function: Does what it
4517 sounds like. Needed when spawning threads.
4519 * root.h: Added member last_debug_frame to root state.
4520 Added #include "libguile/debug.h"
4522 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4523 arguments. The motivation is that code in root.c needs catch
4524 functionality, and we want to avoid code duplication.
4525 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4526 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4527 handlers that run without popping the stack into the dynwind
4530 * throw.h: Added prototypes for scm_catch_apply and
4533 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4535 * root.h (scm_root, scm_set_root): Decouple thread support details
4536 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4537 SCM_SET_THREAD_LOCAL_DATA.
4539 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4540 and tortoise scanning loop.
4542 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4544 * Makefile.in: Rebuild dependencies.
4546 * libguile.h: #include "libguile/print.h" before "smob.h", since
4547 the latter uses the print_state structure.
4549 * throw.c (scm_ithrow): Use the correct variable when checking to
4550 see if a given element of scm_dynwinds is a valid catch.
4552 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4553 structure, abort; don't just silently ignore the garbage.
4555 * _scm.h: #include "print.h" here, since it seems to be used just
4557 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4558 strports.c, unif.h: Don't #include "print.h".
4560 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4562 * feature.h (scm_loc_features): Removed external declaration.
4563 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4565 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4567 * feature.c (scm_init_feature): Added threads feature (needs to be
4568 initialized here, since features doesn't exist when
4569 scm_init_threads is called).
4571 * libguile.h: Added #include "libguile/../threads/threads.h".
4572 (This is a kludge to get thread support working. This should be
4575 * configure.in, acconfig.h: Added flags for thread support.
4577 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4580 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4581 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4584 * _scm.h: Added conditional #include "threads.h"
4586 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4587 SCM_THREADS_SWITCHING_CODE.
4589 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4590 allocate the basic dynamic root object.
4591 (scm_boot_guile): Added call to scm_init_root.
4593 * root.c, root.h: Added root smob.
4594 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4595 functions: Implements dynamic roots mostly according to spec in
4596 SCM manual. Main difference is that the second argument is a
4597 throw handler rather than an error "thunk".
4599 * root.h: Added declaration of scm_init_root.
4601 * root.c: Added #include "genio.h", #include "smob.h", #include
4602 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4604 (scm_init_root): Added #include "root.x".
4606 * throw.c: Added #include "stackchk.h"
4607 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4608 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4609 can be used in scm_call_with_new_root; Added reenabling of stack
4610 checking when catching a throw.
4612 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4614 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4616 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4617 element is not found, as per R4RS.
4619 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4621 * list.c: Doc fixes throughout.
4623 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4625 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4626 declare the char * to be const. Avoids a warning in rgx.c.
4628 * ports.h: spelling fix.
4630 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4633 * load.c (scm_sys_try_load_path): throw an error if file not found
4634 (like it says it in NEWS).
4636 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4638 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4639 PROPS slot to '(), not #f; it's an empty alist.
4641 * throw.h, throw.c: Use SCM_P instead of #if hair.
4643 Remove special support for uncaught throws; see throw.c for
4645 * throw.c (uncaught_throw): New function.
4646 (scm_ithrow): Call uncaught_throw if we don't find a throw
4647 target; don't mess with scm_bad_throw_vcell.
4648 (scm_bad_throw_vcell): Variable deleted.
4649 (scm_init_throw): Don't initialize it.
4651 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4654 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4656 * numbers.c (scm_istr2int): If the number is short (as most
4657 numbers are), just call scm_small_istr2int to deal with it.
4658 (scm_small_istr2int): New function, created by un-#ifdefing the
4659 non-bignum version of scm_istr2int and renaming it.
4661 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4663 * load.c (scm_sys_try_load): don't check whether value returned
4664 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4665 Change the Scheme name from %try-load to primitive-load.
4667 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4668 Can avoid passing a message, allowing it to be derived in the
4669 error handler (e.g., if we want to throw to the key both from
4672 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4674 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4675 references now have a new appearance which is more compact and
4676 also gives a clue about what the target of the reference is.
4677 By setting parameters in the print state, more fancy printing can
4678 be achieved. This is used by the (not yet commited) backtrace
4681 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4683 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4686 * print.c: Added #include "struct.h". Removed function
4689 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4690 scm_iprin1. Removed prototype for scm_prlist.
4692 * arbiters.c (prinarb),
4693 async.c (print_async),
4694 debug.c (prindebugobj, prinmemoized),
4695 eval.c (prinprom, prinmacro),
4696 filesys.c (scm_fd_print, scm_dir_print),
4698 mallocs.c (prinmalloc),
4699 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4700 smob.h (scm_smobfuns),
4701 srcprop.c (prinsrcprops),
4703 unif.c, unif.h (scm_raprin1, rapr1),
4704 variable.c (prin_var): Changed argument `int writing' to
4705 `scm_print_state *pstate'.
4707 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4708 that it will be called before scm_init_print.
4710 * print.c (scm_prin1): Print states are now allocated when calling
4711 scm_prin1 and then passed around to all printing functions as an
4712 argument. A cache `print_state_pool' enables reuse of print
4714 (scm_make_print_state): New function.
4715 (scm_iprin1): Adaption to print states.
4716 (scm_iprlist): An initial "hare and tortoise" scan brings down
4717 time complexity to O (depth * N). (Better time complexity will be
4718 achieved when the printing code is completely rewritten.)
4720 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4722 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4723 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4724 it gets done whether or not the cache variable has a value.
4726 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4728 Distinguish #f and ().
4729 * __scm.h: #undef SICP.
4730 * pairs.h (SCM_EOL): Delete this definition, equating it with
4732 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4733 the value it used to have. Doc fixes, too.
4735 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4737 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4738 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4739 Lord's implementation of structs, allowing for tail arrays as
4740 described in the manual. Also fixed some bugs. (Both the interface
4741 and the implementation should be improved.)
4743 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4745 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4746 People who whish to see the source can do `(print-enable 'source)'.
4747 Removed #ifdef DEBUG_EXTENSIONS.
4749 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4751 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4752 integer (assuming for now accepting an integer is a good thing).
4754 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4755 %S will be used instead for write'ing arguments.
4757 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4758 asserts. fix a few other asserts.
4759 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4760 scm_uniform_vector_ref, scm_array_set_x,
4761 scm_dimensions_to_unform_array): change args in
4762 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4763 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4764 scm_substring_fill_x): likewise.
4765 gsubr.c (scm_gsubr_apply): likewise.
4766 eval.c (SCM_APPLY): likewise.
4768 * eval.c (4 places): replace scm_everr with lgh_error or
4771 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4772 scm_memory_error): new procedures.
4773 scm_everr: deleted. can use scm_wta, dropping first two args.
4774 scm_error: convert NULL subr to SCM_BOOL_F.
4776 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4779 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4782 * error.c, error.h: new error keys: scm_arg_type_key,
4783 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4785 scm_wta: reimplement using lgh_error instead of scm_everr.
4787 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4789 * gdbint.c: scm_lread now has one more argument.
4791 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4792 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4793 loading source from non-file ports, which, e. g., happens when
4794 using the Emacs interface).
4796 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4799 * read.c: Added code for recording of positions of source code
4800 expressions; New functions: recsexpr, scm_lreadrecparen;
4801 _scm_make_srcprops --> scm_make_srcprops
4802 (scm_flush_ws): Removed updating of positions counters. This work
4803 is already done by scm_gen_getc
4805 * read.h: Added prototype for scm_lreadrecparen
4807 * print.c: Added #include "alist.h"
4809 * eval.c: Added #include "hash.h"
4811 * eq.c: Added #include "ramap.h"
4813 * options.c: Documentation fixes.
4815 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
4816 (scm_init_srcprop): Adjusted size of initial source-whash. Name
4817 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
4818 --> scm_make_srcprops
4820 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
4821 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
4822 function calls in the definition of the whash access macros.
4824 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
4826 * init.c (scm_boot_guile): Add level of indirection to
4827 scm_boot_guile_1() to ensure that stack base pointer is properly
4828 initialized. There was no guarantee that variable i was the
4829 highest/lowest variable on stack (i.e. the call frame of
4830 scm_boot_guile was not completely protected from gc).
4832 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
4834 * ports.h (scm_port_table): put back file_name, it will be used to
4835 support debugging. Undo related changes in fports.c, ioext.c,
4838 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4840 * ports.h (scm_port_table): remove file_name member for now, it seems
4842 * fports.c (scm_open_file): don't set file_name in PTAB.
4843 (prinfport): don't use file_name in PTAB.
4844 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
4845 * ports.c (scm_add_to_port_table): don't intialize file_name.
4846 (scm_port_file_name): remove for now.
4847 * gc.c (scm_gc_mark): don't mark PTAB file_name.
4849 * fports.h (scm_mkfile): prototype deleted.
4850 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
4852 * debug.c, unif.c: use scm_out_of_range instead of
4853 wta for range errors (ASSERT still needs work).
4855 * error.c, error.h (scm_out_of_range): new procedure.
4857 * error.c, error.h (scm_out_of_range_key): new key.
4859 * posix.c (scm_sync): #else was missing.
4861 * error.c, error.h: append _key to names scm_num_overflow and
4864 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
4865 of consing an empty list.
4866 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
4867 of macros, saves code and string space.
4868 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
4869 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
4870 lower case. Rename scm_syserror_m to scm_syserror_msg.
4871 error.h: prototypes for new procedures.
4873 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
4875 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
4877 * error.c, error.h: setup scm_num_overflow key.
4879 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
4880 Remove definition of SCM_OVSCM_FLOW.
4882 * fports.c (scm_open_file): use SCM_SYSERROR_M.
4884 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
4885 explicit message and args.
4887 * error.c, error.h, __scm.h: change system_error_sym to
4890 * error.c (system_error_sym): remove leading %% from the Scheme name
4893 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
4895 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4897 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
4898 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
4899 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
4900 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
4901 renamed. (These were introduced by unsupervised name
4904 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4906 * print.c: Added code for detection of circular references during
4907 printing. (init_ref_stack, grow_ref_stack): New functions. Added
4908 a hook for printing of closures (accessible via print options).
4909 This leads to a split of calls to scm_iprin1 into two classes:
4910 elementary print operations (e. g. the code which prints a smob)
4911 still use scm_iprin1 while top level calls (like scm_display) use
4912 scm_prin1. scm_prin1 begins by clearing the data structure used
4913 to record reference information.
4915 * print.h: Added declarations of scm_prin1 and scm_prlist.
4917 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
4919 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
4921 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
4923 * error.c (err_head): scm_iprin1 --> scm_prin1
4925 * debug.c: Adjusted header comment.
4929 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4931 * strerror.c: Doc fix.
4933 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4935 * gdbint.c (gdb_read): Now possible to run during GC.
4936 (unmark_port, remark_port): New functions.
4938 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
4940 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
4941 of allocating a new string object. Also, increase size by
4942 the factor 2 instead of 1.5.
4944 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
4946 * __scm.h (SCM_P): Corrected to run under traditional C.
4948 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
4951 * async.c: Calls to scm_sysintern corrected.
4953 * async.h (scm_async_clock): Redundant declaration removed.
4955 * continuations.c (scm_dynthrow): Redundant declaration removed.
4957 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
4958 Definition typos corrected.
4960 * debug.h: Missing declarations of functions in debug.c added
4963 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
4964 Missing declarations to functions in eval.c added.
4966 * filesys.c: Possibly uninitialized variable rv.
4968 * gc.h (scm_object_addr, scm_unhash_name): Missing
4969 declarations of functions defined in gc.c added.
4971 * genio.c: Possible typos str_data -> wstr_data. ???
4973 * genio.c: Possibly unintended shadowing of local variable
4974 `int c' (gotos out of scope of inner `c'). ???
4976 * init.c: Uninitialized `SCM last' may be used.
4978 * ioext.h: (scm_sys_isatty_p): Typo.
4980 * list.h (scm_list_head): Missing prototype for function in
4983 * numbers.c (scm_two_doubles): Changed from extern to static
4984 (is used only within numbers.c).
4986 * numbers.h: Repeated declarations removed.
4988 * ports.h (scm_close_all_ports_except): Declaration for the
4989 function defined in ports.c added.
4991 * posix.h: Missing declarations added.
4993 * procs.h (scm_make_subr_opt): Missing declaration added.
4995 * socket.h (scm_sys_gethost): Missing declaration added.
4997 * socket.h: Redundant declarations removed (they are in fdsocket.h).
4999 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
5000 Missing declarations added.
5002 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
5004 * struct.c: Uninitialized variable `SCM answer' may be used.
5006 * unif.c (l2ra): Declaration prototype.
5008 * unif.c (scm_array_equal_p): Dummy definition removed (it is
5009 defined in ramap.c).
5011 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
5012 Redundant declarations removed (they are in ramap.h).
5014 * variable.h (scm_make_udvariable,
5015 scm_make_undefined_variable): Declaration corrected to
5016 correspond variable.c.
5018 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
5019 Missing declarations added.
5021 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5023 * Makefile.in (distclean): Don't forget to delete fd.h.
5025 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5027 * fd.h.in, tags.h: Trivial cleanups.
5029 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5030 marksweep.h just declared functions from gc.c.
5031 * gc.h, libguile.h: Don't #include "marksweep.h".
5032 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5033 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5034 dependencies updated.
5036 * libguile.h: Don't #include "files.h"; it's been deleted.
5038 * files.c (scm_sys_delete_file): Moved to filesys.c.
5039 File is now empty; deleted.
5041 * filesys.c: scm_sys_delete_file is now here. Remove
5042 #if's; they seem to rely on remnants of an old portability
5043 regimen. If the problems come up again, solve them properly,
5044 using autoconf. Specifically: Don't test M_SYSV, and #define
5045 remove to be unlink if it's #defined; don't use remove just
5046 because HAVE_STDC_HEADERS is #defined.
5047 * filesys.h: Add declarations for scm_sys_delete_file.
5048 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5049 files.o, files.h, files.c, and files.x.
5050 * init.c: Don't #include "files.h", and don't call scm_init_files.
5052 Use SCM_P instead of PROTO; the latter intrudes on the user's
5054 * params.h: Deleted; definition of SCM_P moved to...
5055 * __scm.h: ... here, where it replaces PROTO macro.
5056 * libguile.h, smob.h: Don't #include "params.h".
5057 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5058 smob.h: Fix prototypes accordingly.
5059 * Makefile.in: Update dependencies.
5060 (inner_h_files): Remove params.h.
5062 * gc.c: #include "gc.h"; every module should include its header,
5063 to let the compiler cross-check the declarations against the
5066 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5067 simpos.h: #include "libguile/__scm.h".
5069 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5071 * init.c: Don't forget to #include smob.h and init.h.
5072 * Makefile.in: Dependencies updated.
5074 * smob.h: Use PROTO instead of #if __STDC__.
5076 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5078 * __scm.h: Doc fixes.
5080 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5081 <angles>; this allows `make depends' to work properly.
5083 * libguile.h: #include smob.h and pairs.h before the others; they
5084 define typedefs used by other headers.
5086 C files should #include only the header files they need, not
5087 libguile.h (which #includes all the header files); the pointless
5088 recompilation was wasting my time.
5089 * Makefile.in (all .o dependency lists): Regenerated.
5090 * libguile.h: Don't try to get a definition for size_t here...
5091 * __scm.h: Do it here.
5092 * _scm.h: Since this is the internal libguile header, put things
5093 here that all (or a majority) of the libguile files will want.
5094 Don't #include <libguile.h> here; that generates dependencies on
5095 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5096 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5097 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5194 * weaks.c: Get "weaks.h".
5196 * stackchk.h: #include "libguile/debug.h",
5198 * print.h, read.h: #include "options.h", since everyone who uses
5199 either of these files will need that.
5201 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5202 anyone who uses this file will need them to define the smob
5203 printing functions. Also, get markers.h, since people will need
5204 to #define the mark functions.
5206 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5207 * ports.h: ... to here.
5209 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5210 don't rely on archaic C default type rules.
5212 * fports.h: #include "libguile/ports.h", since you need that in
5213 order to parse this.
5215 * genio.h: #include "libguile/print.h", because you need that to
5216 parse this; don't bother #including "ports.h", since print.h gets
5219 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5221 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5222 this; it's now a reference to an element of *scm_root.
5224 * debug.h: Don't #include "options.h"; the compiler won't be able
5225 to find that once the headers are installed; instead, #include
5226 "libguile/options.h".
5227 * gc.h: Same, with marksweep.h.
5228 * mbstrings.h: Same, with symbols.h.
5229 * scmhob.h: Same, with _scm.h.
5230 * smob.h: Same, with params.h.
5232 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5233 C files; there's no need for this, and it forces recompilations
5236 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5238 * error.c (scm_error): declare scm_error_callback.
5240 * error.h: prototype for scm_error_callback.
5242 * __scm.h: define lgh_error.
5243 (SCM_SYSERROR): redefine using lgh_error.
5245 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5247 * error.c (scm_error): new procedure.
5249 * error.h: prototype for scm_error.
5251 * Makefile.in (install): install scmconfig.h from the current
5252 directory, not $(srcdir).
5254 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5256 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,

5264 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5265 vports.h, weaks.h: #include "libguile/__scm.h", not
5266 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5267 dependencies are within libguile properly.
5269 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5271 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5272 when scmconfig.h doesn't exist.
5274 * load.c (scm_sys_try_load): Correct spelling.
5276 * feature.c (scm_loc_features): Make this static.
5278 * Makefile.in (libpath.h): Omit trailing slash from path. We
5279 shouldn't require it of users, so why put it here?
5281 Move code to initialize and search %load-path from ice-9 to C
5282 code, so we can use the load-path to find the ice-9 boot code;
5283 this makes it easier to run Guile without installing it. See
5284 corresponding changes in guile/Makefile.in.
5285 * feature.c: Move stuff concerned with the load path to load.c.
5286 (scm_compiled_library_path): Deleted.
5287 Don't #include libpath.h here.
5288 * feature.h: Don't mention scm_compiled_library_path.
5289 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5290 <sys/stat.h>, and <unistd.h> (if present).
5291 (R_OK): #define if the system hasn't deigned to.
5292 (scm_loc_load_path): New variable.
5293 (scm_init_load_path, scm_sys_search_load_path,
5294 scm_sys_try_load_path): New functions.
5295 (scm_init_load): Initialize scm_loc_load_path to point to the
5296 value cell of the Scheme %load-path variable.
5297 * load.h: Add declarations for scm_sys_search_load_path,
5298 scm_sys_try_load_path.
5299 * init.c: Call scm_init_load_path.
5300 * Makefile.in (feature.o, load.o): Dependencies updated.
5302 * load.c, load.h: Rewrite using PROTO macro.
5304 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5306 * gc.c (scm_cellp): New function: C predicate to determine if an
5307 SCM value can be regarded as a pointer to a cell on the heap.
5309 * gc.h: Added declaration of scm_cellp.
5311 * gdb_interface.h: New file: The GDB interface header from the GDB
5314 * gdbint.c: New file: GDB interface.
5316 * gdbint.h: New file: GDB interface.
5318 * libguile.h: Added #include <libguile/gdbint.h>.
5320 * init.c (scm_boot_guile): Added scm_init_gdbint.
5322 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5323 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5324 found if object files and source are kept separate).
5326 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5328 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5330 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5332 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5333 TK_SRC_DIR; they're not relevant any more.
5335 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5336 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5338 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5340 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5341 search path, so we can find the <libguile/MUMBLE.h> headers.
5343 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5345 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5346 implicit in the .c.o rule.
5347 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5350 Put the library path in a header file, instead of passing it on
5351 the command line in every compilation.
5352 * Makefile.in (libpath.h): New target.
5353 (feature.o): Depend on libpath.h.
5354 (clean): Delete libpath.h.
5355 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5356 * feature.c: ... #include "libpath.h" here.
5357 * .cvsignore: Ignore libpath.h.
5359 Don't install the unwashed masses of Guile header files in the
5360 main #include path; put most of them in a subdirectory called
5361 'libguile'. This avoids naming conflicts between Guile header
5362 files and system header files (of which there were a few).
5363 * Makefile.in (pkgincludedir): Deleted.
5364 (innerincludedir): New variable; this and $(includedir) are enough.
5365 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5366 (installed_h_files): Divide this up. Now this variable lists
5367 those header files which should go into $(includedir) (i.e. appear
5368 directly in the #include path), and ...
5369 (inner_h_files): ... this new variable says which files appear in
5370 a subdirectory, and are referred to as <libguile/mumble.h>.
5371 (h_files): List them both.
5372 (install): Create innerincludedir, not pkgincludedir. Put
5373 the installed_h_files and inner_h_files in their proper places.
5374 (uninstall): Corresponding changes.
5375 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5376 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5377 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5378 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5379 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5380 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5381 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5382 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5383 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5384 vports.h, weaks.h: Find __scm.h in its new location.
5385 * __scm.h: Find scmconfig.h and tags.h in their new locations
5386 (they're both "inner" files).
5388 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5390 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5392 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5394 * posix.c: Doc fixes.
5396 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5398 * socket.c: Don't include a prototype for inet_aton; just use a
5399 K&R style declaration, to avoid warnings but minimize the chance
5400 of conflicts with the system.
5402 On NextStep, <utime.h> doesn't define struct utime, unless we
5403 #define _POSIX_SOURCE before #including it.
5404 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5405 * acconfig.h: New comment text for above CPP symbol.
5406 * configure.in: Call it.
5407 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5409 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5411 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5412 testing for __EMX__.
5414 * posix.c: #include <libc.h>, if it exists.
5416 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5417 don't even know if the latter exists.
5419 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5420 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5421 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5423 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5425 (scm_init_posix): Use them when initializing the Scheme constants
5428 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5430 * Makefile.in (libdir, includedir, bindir): Use the
5431 autoconf-supplied values, instead of deriving them ourselves.
5432 (pkgincludedir, datadir, pkgdatadir): New variables.
5433 (install, uninstall): Put the header files in a special
5434 subdirectory, not in the main search path.
5436 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5437 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5439 * Makefile.in (IMPLPATH): Deleted; never used.
5441 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5442 on the Tcl/Tk source any more.
5443 (INCLUDE_CFLAGS): Remove references to the above.
5445 * Makefile.in (version.o): Corrected dependencies.
5447 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5449 * libguile.h: #include "version.h"
5451 * init.c (scm_boot_guile): Call scm_init_version.
5452 * gscm.c (gscm_run_scm): Call scm_init_version.
5454 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5455 GUILE_VERSION): AC_DEFINE these.
5456 (acconfig.h): #undef the above symbols.
5458 * Makefile.in (libobjs): Add version.o.
5459 (installed_h_files): Add version.h.
5460 (c_files): Add version.c.
5461 (gen_c_files): Add version.x.
5462 (version.o): New rule.
5463 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5464 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
5465 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
5466 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
5467 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
5468 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
5469 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
5470 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
5471 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
5472 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5473 weaks.o): Add version.h to dependency lists.
5474 (markers.o): Remove duplicate rule.
5476 * version.h: New file.
5478 * version.c: New file.
5480 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5482 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5483 array; use it appropriately. Since GCC is quite happy to
5484 subscript functions, it never warned us about this; we should use
5485 -Wpointer-arith in the future. I guess we never tested
5488 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5490 * socket.c: Doc and copyright fixes.
5492 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5494 * debug.c: Fixed and improved gdb support.
5496 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5498 * socket.c: Added declaration of inet_aton to avoid compiler
5499 warning. (Hope this solution is correct.)
5501 * stime.c: Added declaration of ftime. (This is missing in
5504 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5506 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5508 * Makefile.in (c_files): add strerror.c.
5510 * strerror.c: new file from Emacs' sysdep.c.
5511 maybe configure should also check for sys_errlist.
5513 * configure.in (AC_REPLACE_FUNCS): add strerror.
5515 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5517 * debug.c (scm_init_debug): Added initialization for
5518 scm_evaluator_traps.
5520 * debug.h, debug.c: Various name changes.
5521 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5522 "debug-options-interface". See commentary in options.c.
5524 * options.h, options.c: Options now have documentation strings.
5525 Also added a long explanatory commentary.
5527 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5530 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5531 last_debug_info_frame is now updated in all cases.
5533 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5536 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5538 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5539 Added option STACK_CHECKING.
5541 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5543 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5545 * __scm.h: Removed symbols for debugging support.
5547 * acconfig.h: Added symbols for debugging support.
5549 * configure.in: Added user option for debugging support.
5550 --enable-debug will include the debugging code into libguile.a.
5552 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5553 scm_relocate_chunk_to_heap.
5555 * debug.c: New file: low-level debugging support. It also
5556 includes support for debugging with gdb. (The extensions to gdb
5557 are written by Per Bothner at Cygnus.)
5559 * debug.h: New file: low-level debugging support.
5561 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5562 argument pairs. Extensive modifications to the debugging
5563 evaluator. Added "SECTION:" commentaries to clarify what happens
5564 when, during double compilation. Renamed EVALIMP --> EVALIM.
5565 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5566 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5567 the beginning of the file. New procedure: scm_unmemocopy.
5568 Added some global state variables needed by the debugging
5569 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5570 check_entry, check_apply, check_exit, debug_options and
5571 evaluator_traps. New acro: undefine.
5573 * eval.h: Renamed EVAL --> XEVAL.
5575 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5576 --> scm_make_weak_key_hash_table.
5578 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5579 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5581 * libguile.h: Conditionally include debug.h
5583 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5584 scm_object_properties shouldn't return handle. `handle' now gets
5585 initialized in scm_set_object_properties_x. scm_object_properties
5586 doesn't any longer create an entry in scm_object_whash.
5588 * options.c: New file: handling of run time options.
5590 * options.h: New file: handling of run time options.
5592 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5594 * print.c: New procedure: scm_print_options
5596 * print.h: Defines for print options.
5598 * read.c: New procedure: scm_read_options
5600 * read.h: Defines for reader options.
5602 * root.h: Added scm_source_whash among scm_sys_protects.
5604 * srcprop.c: New file: source properties.
5606 * srcprop.h: New file: source properties.
5608 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5609 (Bug found by A. Green.)
5611 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5613 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5615 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5617 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5619 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5620 and should be called by the final client.
5622 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5624 * gc.h: Use the PROTO macro when declaring functions.
5625 * gc.c: Use the PROTO macro when declaring static functions.
5626 Remove the CPP hair around function definitions.
5628 * gc.c (scm_init_storage): Initialize scm_asyncs.
5630 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5631 preprocessor symbol; "__scm.h" is where it might get #defined.
5632 * __scm.h: Similar: #include <scmconfig.h> before testing
5635 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5637 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5639 * init.c (scm_boot_guile): Add init_func argument; call
5640 (*init_func) instead of calling scm_appinit; it's ucky to
5641 hard-code names for the user's procedures.
5642 * init.h (scm_boot_guile): Adjust declaration.
5644 * __scm.h (PROTO): New macro, for declaring functions with
5647 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5648 eliminate all the __STDC__ conditionals.
5649 (scm_boot_guile): Add declaration.
5650 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5651 Remove __STDC__ conditionals around function definitions; the
5652 declarations in init.h will provide the same information, more
5655 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5656 complain about it in the error message; the error message is
5657 adequate without that note, and there's nothing the user can do
5660 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5662 * Makefile.in (ancillary): Drop def.sed.
5664 * posix.c (scm_init_posix): Use numeric values, rather than
5665 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5666 F_OK. The symbols aren't available on some systems, and I'm
5667 pretty sure their values are fixed by common widespread practice.
5668 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5670 More functions unavailable on some systems.
5671 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5672 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5674 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5675 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5676 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5677 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5678 stub that signals an error as the #else.
5680 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
5682 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
5684 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
5686 * unif.c: include ramap.h.
5688 * read.c (endif): case_insensative_p renamed case_insensitive_p.
5690 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
5692 * ports.c: include sys/ioctl.h.
5694 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
5696 * configure.in: check for sys/ioctl.h.
5698 * ports.c: include <malloc.h> not "malloc.h".
5700 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5702 * fports.c: remove ttyname and tmpnam declarations.
5704 * posix.c: fewer ttyname declarations.
5706 * fports.c: include <string.h> not "string.h".
5708 * init.c, ioext.c: include string.h and unistd.h.
5710 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5712 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
5713 genio.c, simpos.c, vports.c: include string.h.
5715 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
5717 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
5719 (scm_addr_buffer_size): change type from scm_sizet to int.
5720 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
5721 from scm_sizet to int.
5723 * error.c: include unistd.h.
5725 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
5728 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
5730 * __scm.hd, def.sed: deleted.
5732 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
5734 Changes for NeXT, suggested by Robert Brown.
5735 * configure.in: Call AC_TYPE_MODE_T.
5736 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
5737 NeXT. Put header file list in alphabetical order.
5738 * configure, scmconfig.h.in: Regenerated.
5739 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
5741 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
5744 * acconfig.h: New file, providing documentation for the CPP
5745 symbols defined in configure.in
5746 * acconfig-1.5.h: Removed; superceded by the above.
5748 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
5750 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
5752 * fports.c (scm_open_file): don't return #f, throw error.
5754 * ioext.c (fileno): renamed from %fileno.
5755 (soft-fileno): deleted.
5757 * ports.c (scm_port_revealed): don't need to check for -1 from
5759 (scm_set_port_revealed_x): return unspecified, not #f.
5761 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
5763 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
5765 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
5767 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.

5771 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5772 This is necessary on Ultrix, and doesn't hurt portability.
5774 * Makefile.in (dist-dir): New target, implementing a new dist system.
5775 (installed_h_files): Put in alphabetical order.
5776 Remove duplicate entries for markers.h and unif.h.
5777 (c_files): Remove duplicate entries for markers.c.
5778 (ancillary): Renamed from anillery; all uses changed. Remove
5779 PLUGIN; it's a directory, and needs special treatment in dist-dir.
5780 Remove all the ../doc/* files; doc/Makefile.in handles that.
5782 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5784 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5785 every if must have an else, or else the whole command has a
5786 non-zero exit code whenever the if's condition is false.

5853 matter so long as it is non-0 (got rid of "* 4").
5855 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
5857 * gscm.h: gscm_mkarray eliminated (presumably was not being used
5858 since its definition was bogus).
5860 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
5862 * mallocs.[ch]: back again (for rx at least).
5864 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
5866 * ports.c: removed functions relating to the mapping between ports
5867 and descriptors. (That stuff is unix-specific and should be collected

5875 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
5876 handled correctly (SCM_FREEP was applied to them) -- test for

6045 initialization to fix a race condition.
6047 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

6074 The weird symbol syntax is also a bit bogus (emacs doesn't quite
