1 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
3 * libguile.h: Don't omit the dynamic linking functions. (Thanks
6 * genio.c (scm_do_read_line): Count lines correctly when the file
7 doesn't end in a newline.
9 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
11 * genio.c (scm_do_read_line): Maintain the line count correctly.
12 (Thanks to Harvey J. Stein and Greg Harvey.)
14 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
17 * numbers.c (big2str): Protect t from garbage collection until
18 we're done. (Thanks to Gary Houston.)
20 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
22 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
24 * Makefile.in: Regenerated.
26 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
27 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
30 Do magic to mix reads and writes on stdio FILE-based ports.
31 (Thanks to Christian Lynbech.)
32 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
34 (pre_read, pre_write): New functions.
35 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
36 local_fputs): Call them.
37 (local_fflush): Mark the port as ready for reading and writing.
38 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
39 flags on new port objects. This might not be accurate --- who
40 knows what state the FILE * is in when we get it --- but it won't
41 do extraneous calls to fflush or fseek, so it's no worse than the
42 behavior before this change.
43 * ports.h: Add comment.
45 Centralize the creation of port objects based on stdio FILE * in
46 fports.c; don't just throw them together anywhere.
47 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
48 what the rest of Guile wants. Don't set the revealed count;
49 that's only appropriate for stdin, stdout, stderr.
50 (scm_standard_stream_to_port): This function does set the revealed
52 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
53 not scm_stdio_to_port.
54 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
55 * fports.c (scm_open_file): Same.
56 * posix.c (scm_pipe): Same.
57 * socket.c (scm_sock_fd_to_port): Same.
58 * ioext.c (scm_fdopen): Same.
59 (scm_freopen): Moved from here to...
60 * fports.c (scm_freopen): ... here. This is really something that
61 munges the internals of an fport, so it should go here.
62 * fports.h (scm_stdio_to_port): Adjust prototype.
63 (scm_standard_stream_to_port, scm_freopen): New protoypes.
64 * ioext.h (scm_freopen): Prototype removed.
66 * filesys.c (set_element, get_element): This can work on both pipe
67 and file ports, so use SCM_FPORTP to typecheck, instead of testing
70 * scmconfig.h.in: Regenerated.
72 Change the definition of the functions in scm_ptobfuns so that
73 they get passed the port object, not the port's stream.
74 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
75 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
76 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
77 Pass the port itself to the scm_ptobs function.
78 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
79 scm_generic_fgets): Same.
80 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
81 getc_void_port, fgets_void_port, close_void_port): Just change the
82 argument names; these functions don't really do anything.
83 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
84 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
85 port as an argument, and use SCM_STREAM to get the stdio FILE *.
86 Also, use prototyped definitions, and get rid of the extra
88 (scm_fptob, scm_pipob): We don't need casts here any more.
89 * strports.c (prinstpt): Use prototype declarations.
90 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
91 and use SCM_STREAM to get the string info. Also, use prototyped
92 definitions, and get rid of the extra declarations.
93 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
96 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
97 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
99 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
100 scm_fgets, for consistency.
101 (scm_fptop, scm_pipob): References updated.
103 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
105 Include the source location in error messages for scripts.
106 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
107 stack is still there when we catch the error.
108 * throw.c (handler_message): If we are handling an error with a
109 message, then put together the proper arguments and call
110 scm_display_error, instead of scm_display_error_message. That
111 displays source location, if it can find it.
113 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
115 * gc.c (scm_unprotect_object): Change this so that calls to
116 scm_protect_object and scm_unprotect_object nest properly.
117 (scm_protect_object): Doc fixes.
119 * strings.c (scm_string_set_x): Require the argument to be a
120 writable string, not a substring or a symbol.
121 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
122 (Thanks to John Redford and Charbel Jacquin.)
124 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
126 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
128 * eval.c (safe_setjmp): Remove this misunderstanding.
129 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
132 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
134 * libguile.h: Mark these as C declarations, for compilation by C++
137 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
138 __cplusplus clause. I seriously doubt this ever worked the way
139 the author seems to have intended.
141 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
143 Utterly needless cleanups to hopelessly messy code.
144 * ports.c: Doc fixes.
145 (scm_fflush): Moved to ...
146 * genio.c (scm_fflush): ... here, amongst all the other port
147 method invocation functions.
148 * genio.h, ports.h: The prototype moves too.
150 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
152 * backtrace.c (display_error_body): The current frame does not
153 always have a parent frame; consider a function called directly
154 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
157 * alloca.c (alloca): Undo yesterday's changes, and simply call
158 malloc directly for storage, and abort if we don't get what we
159 want. The situation is much simpler --- just call malloc. Emacs
160 has bizarre/evil requirements (signal handlers might malloc unless
161 you set this global flag, so you have to set the flag around all
162 calls to malloc) which we are certainly not going to conform to,
163 so we can do the simple and obvious thing.
165 * coop.c (coop_condition_variable_wait): Make this function
166 static. It's only useful internally --- you should never just
167 wait on a condition variable.
168 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
170 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
172 * unif.c (scm_array_set_x): Accept any kind of number as an
173 element for a uniform vector of doubles. This is more consistent
174 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
176 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
177 works; I can't conveniently test it myself. (Thanks to Dvid
178 Tillman for the bug report.)
182 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
183 from here, not from scm_compile_shell_switches (which is a pretty
184 dumb place to do it).
185 (scm_load_startup_files): New function.
186 (scm_ice_9_already_loaded): Variable moved to here from script.c.
187 * script.c (scm_compile_shell_switches): Don't load the startup
189 (scm_ice_9_already_loaded): Variable moved.
190 * init.c (scm_load_startup_files): Prototype for new function.
191 * gh_init.c (gh_enter): Doc fix.
193 1998-10-03 <jimb@savonarola.red-bean.com>
195 Some anti-warning changes from Greg Harvey.
196 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
197 warnings when it doesn't understand our NORETURN declarations in
199 * posix.c (scm_mknod): Similar.
201 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
203 * posix.c (scm_getpwuid): If we can't find an entry, return our
204 own message, instead of using scm_syserror --- the getpwMUMBLE
205 functions don't set `errno' to anything interesting.
207 1998-10-03 <jimb@savonarola.red-bean.com>
209 Get rid of warnings from the cooperative threading system.
210 * threads.h (scm_single_thread_p, scm_yield,
211 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
212 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
213 scm_wait_condition_variable, scm_signal_condition_variable): Add
214 prototypes for these Scheme-visible functions.
215 * coop-defs.h (coop_next_runnable_thread,
216 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
217 Prototypes for these here, even though they're from iselect.c.
218 (coop_condition_variable_wait, coop_join): Add prototypes.
219 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
220 scm_threads_free_condvar): Make these smob functions static.
221 * coop-threads.h (coop_init): Give this a real prototype.
222 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
223 (coop_next_runnable_thread): No need to provide prototype; it's in
226 * scmconfig.h.in: .detarenegeR
228 * iselect.c, threads.c: Doc fixes.
230 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
232 * Makefile.in: Regenerated with a patched automake, to get
233 dependency generation right when using EGCS.
235 * inet_aton.c (inet_aton): Add prototype, to remove compiler
236 warning. (Thanks to Robert Pluim.)
238 * inet_aton.c (inet_aton): Reassure the compiler that the
239 arguments to the <ctype.h> macros are all unsigned characters, not
242 1998-10-03 <jimb@savonarola.red-bean.com>
244 Getting rid of more warnings...
245 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
246 today's change to ../configure.in.
247 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
248 * scmconfig.h.in: Regenertaded.de.,.__
249 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
250 (scm_localtime, scm_mktime): Use a const char * to manipulate the
253 * readline.c: Doc fix.
254 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
255 * readline.h (scm_filename_completion_function): Add prototype.
256 (scm_init_readline): Make this into a prototype.
258 * readline.c (scm_filename_completion_function): Use SCM_PROC to
259 declare this, instead of calling scm_make_subr manually.
261 1998-10-02 <jimb@savonarola.red-bean.com>
263 * readline.h (scm_init_readline): Add prototype for this.
264 (scm_init_readline): Make this a real prototype.
266 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
268 Warning fixes from Maciej Stachowiak:
269 * backtrace.h (scm_display_application, scm_backtrace): Add
271 * debug.c (scm_m_start_stack): Make this function static.
272 * fluids.h (scm_fluid_p): Add prototype.
273 * procprop.c (scm_i_procedure_arity): Make this function static.
274 * regex-posix.c (scm_regexp_error_msg): Make this function static.
275 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
276 * root.h (scm_dynamic_root): Add external prototype.
277 * scmsigs.h (scm_usleep): Add external prototype.
278 * script.h (scm_init_script): Use prototype, not K&R decl.
279 * stacks.h (scm_stack_id): Add external prototype.
280 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
282 1998-09-30 Mark Galassi <rosalia@cygnus.com>
284 * gh.h: took out the definitions of vset and vref, since they are
285 replaced by the proper vector routines that correspond to the R4RS
288 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
290 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
291 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
292 third argument, a C expression that should result in a SCM value,
293 which is used to initialize the variable. Reimplemented
294 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
297 * version.h (scm_libguile_config_stamp): Add prototype.
298 (From Maciej Stachowiak.)
300 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
302 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
303 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
305 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
307 * print.c (scm_iprin1): Rather than having one i, and using it in
308 several places, declare a fresh i local to each block where it is
309 used, and give it a signedness appropriate to its use in each case.
312 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
315 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
316 signed/unsigned clashes.
318 * posix.h (scm_tmpnam): Added prototype.
320 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
321 scm_make_subclass_object): Add external prototypes.
323 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
324 comparison is okay here.
326 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
328 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
329 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
331 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
334 * load.c (swap_port): Make this function static.
336 * load.c (scm_search_path): Make max_path_len and max_ext_len
337 unsigned, since they're compared against string sizes.
339 * load.c (init_build_info): Make i unsigned.
341 * ioext.h (scm_read_line): Add prototype.
343 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
344 scm_hash_fn_remove_x): Make hash bucket index local variable k
345 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
346 accurately as possible.
348 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
349 comparisons, and range checking to make sure those casts are
352 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
353 signed/unsigned comparisons.
355 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
356 avoid signed/unsigned comparisons.
357 * smob.h (scm_numsmob): Change extern declaration to match.
359 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
360 avoid signed/unsigned comparisons.
361 * ports.h (scm_numptob): Change extern declaration to match.
362 (scm_current_load_port, scm_set_port_line_x,
363 scm_set_port_column_x): New prototypes.
365 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
366 test code, and it causes warnings.
368 * gh.h (gh_int2scmb, gh_uniform_vector_length,
369 gh_uniform_vector_ref): Added prototypes.
371 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
372 debugging support unconditionally. That's backtrace.c, stack.c,
373 debug.c, and srcprop.c.
374 (EXTRA_libguile_la_SOURCES): Omit those from here.
375 * Makefile.in: Regenerated.
377 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
379 * options.c (scm_options): Bugfix: Allow empty list of options!
381 * debug.c, debug.h (scm_single_step): Removed.
382 (scm_with_traps): New procedure. This procedure could easily be
383 written in Scheme but needs to be highly optimized.
385 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
387 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
388 Check SCM_TRAPS_P before trapping.
390 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
392 Changes to avoid signed/unsigned comparison warnings.
393 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
394 (scm_gc_sweep): Make n and j local to the blocks they're used in,
395 so they can have appropriate types for each application. Make i
396 signed. Use initializers in some spots. I'll probably pay for
398 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
399 (scm_must_realloc): Make nm unsigned.
400 (init_heap_seg): Make new_seg_index and n_new_objects signed.
401 (scm_init_storage): Use prototype-style definition, and make the
403 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
404 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
406 * filesys.c (scm_readlink): Make local vars rv and size ints, to
407 avoid signed/unsigned comparison warnings, and because the return
408 value of readlink may be -1. Don't bother casting the third
409 argument to readlink.
411 * filesys.c (scm_dirname, scm_basename): Move these to their own
412 page, at the end of the file.
413 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
415 * eval.h (scm_eval_options_interface): Add external prototype for this.
416 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
418 * eval.c (scm_lookupcar1): Make this static.
420 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
421 Make these prototype declarations, not K&R-style.
423 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
424 unsigned comparison warning.
426 * appinit.c: File removed. It had a single function in it, empty,
427 whose reason for existence is explained in no documentation or
428 comment. I think it's there as a default for some Tcl-style
429 initialization, but Tcl abandoned that approach a while ago.
430 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
431 (BUILT_SOURCES): Remove appinit.x.
432 * Makefile.in: Regenerated.
434 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
436 * Makefile.in: Regenerated using the last public version of
437 automake, not the hacked Cygnus version.
439 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
441 Remove Totoro kludge.
442 * Makefile.in, scmconfig.h.in: Regenerated.
443 * init.c, readline.c: Don't check if TOTORO is #defined.
445 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
447 * Makefile.am: Adjust for new thread configuration system.
448 (INCLUDES): Include the value of THREAD_CPPFLAGS.
449 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
451 (THREAD_LIBS): Definition deleted; automake will generate such
452 things automatically.
453 * Makefile.in: Regenerated.
455 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
457 Simplify smob and port marking; set the mark bit in the generic
458 marking code, and make marker routines only responsible for
459 turning up outgoing pointers.
460 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
461 before calling the marking function. Don't call the marking
462 function if it's zero.
463 * markers.c (scm_mark0): Just return #f. This function isn't
464 necessary at all now, but it's harmless to call it. We'll leave
465 it in so other folks' code doesn't croak at link time.
466 (scm_markcdr): Don't call SCM_SETGC8MARK.
467 * async.c (mark_async): Don't call SCM_SETGC8MARK.
468 * dynl.c (mark_dynl_obj): Same.
469 * root.c (mark_root): Same.
470 * srcprop.c (marksrcprops): Same.
471 * unif.c (markra): Same.
472 * variable.c (scm_markvar): Same.
473 * ports.c (scm_markstream): Same.
474 (void_port_ptob): Specify zero for our marking function.
475 * debug.c (debugobjsmob): Same.
476 * dynwind.c (guardsmob): Same.
477 * filesys.c (dir_smob): Same.
478 * fluids.c (fluid_smob): Same.
479 * fports.c (scm_fptob, scm_pipob): Same.
480 * mallocs.c (mallocsmob): Same.
481 * regex-posix.c (regex_t_smob): Same.
482 * smob.c (freecell, flob, bigob): Same.
483 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
484 * throw.c (jbsmob, lazy_catch_funs): Same.
486 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
488 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
489 scm_copy_tree on code in order not to let memoized code to leak
490 out. Thus, scm_copy_tree needs to copy vectors as well since
491 quasiquote can introduce evaluated code also inside vector
494 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
496 * eval.c (scm_copy_tree): Removed ability to copy vectors.
498 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
499 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
502 * unif.c: Say that ivect and uvect are of type signed and unsigned
503 long instead of int in commentary so that it correctly describes
506 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
508 * stime.c: Removed declaration of strptime. (It should be
509 declared by the system headers. If it turns out that some systems
510 don't, we'll handle that then.) (Thanks to Greg Troxel.)
512 * stime.h: Renamed TIMEH --> STIMEH
514 * backtrace.c (scm_display_error, scm_display_backtrace): In order
515 to increase portability, don't use structure assignment.
516 (Thanks to Nicolas Neuss.)
518 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
520 (finalize_fd_sets): Added empty statement after last case label.
521 (Thanks to Nicolas Neuss.)
523 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
526 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
528 * init.c, readline.c: OK, I won't have these readline.x bug
529 reports anymore. We've had them since April. The current reason
530 is a completely unintelligible failure of totoro.red-bean.com to
531 do the test for rl_getc_function in libreadline correctly. This
532 kludge overrides the test if we're on totoro so that the snapshot
533 generation process can work.
535 * readline.c: Define a strdup replacement if not existent on system.
537 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
539 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
540 This change makes scm_make_vector R5RS compatible. We cannot keep
541 the third argument since people want to be able to deduce the form
542 of the C function call only by looking at R5RS. (At the same time
543 we have removed some unnecessary complexity!)
545 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
546 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
547 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
548 argument in call to scm_make_vector.
550 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
552 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
553 This macro is useful in applications.
555 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
557 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
558 (scm_parse_path, scm_search_path): New Scheme level procedures.
560 * load.h (scm_internal_parse_path, scm_parse_path,
561 scm_search_path): Declared.
563 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
565 * filesys.c (dirname, basename): New procedures.
567 * init.c (scm_boot_guile_1): Removed condition around
570 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
571 new data type (guards) for representation of C level guards and
572 data on the wind chain.
573 (scm_internal_dynamic_wind): New function.
575 * dynwind.h: Declare scm_internal_dynamic_wind.
577 * root.h (scm_root_state): Added scm_cur_loadp.
579 * root.c (mark_root): Added comment about cur_loadp.
581 * load.c: #include "dynwind.h";
582 (scm_primitive_load): Use scm_inner_dynamic_wind to update
585 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
587 * ports.c (current-load-port): New procedure.
589 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
591 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
592 not a tty, return #f.
594 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
595 to Julian Satchell and Roland Kaufmann.)
597 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
598 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
600 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
602 * debug.h, debug.c (scm_start_stack): New function. Implements
603 the guts of old scm_m_start_stack.
605 * debug.c (scm_m_start_stack): Use scm_start_stack.
607 * init.c (scm_start_stack, scm_restart_stack): Renamed to
608 start_stack and restart_stack. (These have static scope.)
610 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
612 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
613 readline functions to come in release 2.3. (Thanks to Chet
615 (handle_errors): Use the above functions.
617 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
619 * readline.c: Improvements for readline support: Handle errors
620 better; Implement before-read-hook.
622 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
624 * init.c (scm_boot_guile_1), readline.c: Test for
625 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
626 assure that we have version >= 2.1.)
628 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
630 * readline.c (scm_readline): Defer interrupts while we're calling
633 * readline.c (scm_add_history): Bugfix: Do strdup before giving
634 away the string to add_history.
635 (completion_function): Do completion for readline. (Thanks to
637 (scm_filename_completion_function): New procedure: Filename
639 (current_input_getc): New function. Use this one instead of
640 standard getc from readline.
642 * throw.c, throw.h (scm_handle_by_throw): New function: This
643 handler throws errors to next handler on the dynwind chain.
645 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
647 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
650 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
652 * procprop.c (scm_i_procedure_arity): New function. Returns arity
654 (scm_procedure_properties): Modified to return arity together with
656 (scm_procedure_property): Added the read-only property `arity'.
657 (scm_set_procedure_property_x): It is an error to set the `arity'
660 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
661 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
663 * procprop.h (scm_sym_arity): New symbol.
665 * objects.c (scm_set_object_procedure_x): New procedure: Use this
666 to set the dispatch procedure of an operator or entity object.
668 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
669 Made procedure slots read-only.
671 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
672 scm_tcs_cons_gloc case in zero args switch; Fixed args
673 construction for operators in scm_tcs_cons_gloc case in two args
676 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
678 * fluids.c: Removed use of assert.h (in order to avoid
681 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
683 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
685 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
686 change makes the evaluator safer at the cost of evaluation speed.
687 It handles the case when the user has added a non-immediate
688 improper end of the application form, e.g., `(+ 0 . x)'.
689 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
690 minimize the extra cost as much as possible. The new code is
691 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
692 problem with structs planted directly in the code (e.g. by a
693 macro). This no longer causes segmentation fault. (Thanks to
696 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
697 arg `proc' in order to be able to throw errors; New argument
700 * Removed extra #include "debug.h"
702 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
704 * scmsigs.c: Declare usleep as returning void on some systems.
705 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
708 * coop.c (usleep): Return void on some systems.
710 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
712 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
714 * coop.c: Changed return type of usleep to int.
716 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
717 isn't found in the OS.
719 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
720 isn't enabled. (Thought that I had made this change ages ago...)
722 * iselect.c: Declare bzero if not defined by OS.
724 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
726 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
727 condition. (Thanks to John Tobey.)
729 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
730 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
733 * __scm.h: Start the long-term project of moving to POSIX threads.
734 Phase 1: Classification of all critical sections.
735 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
736 for A sections. (See comments in __scm.h for details.)
738 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
739 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
741 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
743 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
744 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
745 (libpath.h, versiondat.h): Replaced dependency on Makefile with
746 dependencies on $(srcdir)/Makefile.in
747 $(top_builddir)/config.status in order to avoid circularity.
749 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
750 from argc if argc was 0 initially.
752 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
753 in generation of libpath.h.
755 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
757 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
758 libguile from 2 to 3.
760 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
762 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
764 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
766 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
767 scm_set_port_column_x, scm_port_filename,
768 scm_set_port_filename_x): Removed optional arguments. Added
769 proper argument checking.
771 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
772 stack size in machine words.
774 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
775 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
776 to Ole Myren Röhne.)
778 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
780 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
781 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
783 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
786 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
787 procedure apply: Copy argument lists before pushing them unto the
788 environment so that the environment won't get mutated due to
789 manipulation of procedure arguments. This should perhaps be
790 regarded as a temporary solution until someone finds a more
791 efficient one. (Thanks to Maciej Stachowiak.)
793 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
795 * script.c (scm_compile_shell_switches): Use "guile" as default
796 zero arg if argc is NULL.
798 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
800 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
801 is zero. (Thanks to Dirk Herrmann.)
803 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
805 * ports.c (scm_add_to_port_table): First line is now line 0
806 (was 1). (Interface changed according to suggestion by Per
809 * backtrace.c (display_header): Add 1 to line and column numbers
810 when presenting them to the user.
812 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
813 from debug.c --> eval.c
815 * eval.h, eval.c (scm_eval_options_interface): New options
817 (SCM_EVAL_STACK): New option: Size of newly created stacks,
818 i.e. stacks for new threads.
820 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
822 * eval.c (unsafe_setjmp): Removed with #if 0.
824 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
827 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
828 to avoid compiler warnings.
830 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
832 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
834 * throw.c (handler_message): Print message on current error port
835 instead of default error port. (Thanks to Maciej Stachowiak.)
837 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
839 * ports.c (scm_add_to_port_table): allocate in units of
840 struct scm_port_table *, not struct scm_port_table.
841 * posix.c (scm_close_pipe): remove the port from the port table
843 Thanks to Rob Engle for both fixes.
845 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
847 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
848 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
850 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
852 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
854 * backtrace.c (display_error_body, display_backtrace_body),
855 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
856 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
857 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
858 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
861 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
862 don't receive the jmpbuf arg anylonger.
863 (scm_catch): Don't accept a #f tag.
864 (scm_throw): Check that key is a symbol.
865 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
867 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
869 * async.c (async_pending): Removed declaration.
871 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
873 * dynwind.c (scm_wind_chain): New debug function.
875 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
876 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
877 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
878 extra layer of functions around the body and handler of a thread.
879 This extra layer makes sure that the handler is called in the
880 dynamic context of the surround (= empty dynwind list), but under
881 the *dynamic root* of the body. We can not use the dynamic root
882 of the surround since that root belongs to another thread => stack
883 is not handled correctly. It may seem ugly to use this extra
884 layer, but the extra cost in terms of execution time is really
885 negligible compared to the total amount of time required to create
886 a thread, and it would reduce maintainability to duplicate the
887 crucial and complicated steps performed by cwdr.
889 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
890 (SCM_ALLOW_INTS): Added thread switching code before interrupts
891 get re-enabled. The important effect of this is that interrupts
892 are blocked during thread switching so that thread data structures
893 don't risk getting messed up by an unfortunate signal.
894 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
895 seems to do more aggressive optimization which actually move
896 instructions around in these macros in a fatal way. Therefore:
897 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
898 just superstitious...)
899 (SCM_TICK): Maybe do a context switch and take care of asyncs.
900 This macro should be used instead of SCM_ASYNC_TICK since the
901 latter doesn't do context switches any more.
903 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
904 instead of SCM_ASYNC_TICK.
906 * coop.c, iselect.c: Since thread switches are now performed with
907 interrupts masked, we can't use the old mechanism of delivering
908 signals immediately when they arrive. Signals must instead be
909 delivered when the asyncs run *after* the end of the critical
910 section in scm_internal_select. But this also means after context
911 switch so that the signal will be delivered to a different thread.
912 To avoid this, I have changed the protocol of
913 coop_wait_for_runnable_thread and friends so that they are allowed
914 to return the original thread. So, if a signal arrives during
915 scm_internal_select, we won't any longer be forced do a context
916 switch, but can remain in the same thread and deliver the signal
919 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
920 scm_asyncs_pending and made it global.
922 * iselect.c: Small fixes.
924 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
925 coop_condition_variable_init, coop_condition_variable_wait,
926 coop_condition_variable_signal): Changed return type from `void'
927 to `int'. This is to adhere closer to the pthreads interface.
928 This, in turn, is part of an attempt to provide C versions of the
929 mutex and condition variable primitives which can be part of a
930 frontend to COOP or pthreads.
932 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
933 coop_condition_variable_destroy): New functions.
935 * coop-threads.c (scm_wait_condition_variable): Use
936 coop_condition_variable_wait_mutex.
938 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
939 Definitions moved to coop-defs.h.
941 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
942 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
943 scm_cond_destroy): New C interface to mutecis and cond vars.
945 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
947 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
949 * iselect.c: Now several threads can wait on the same file
950 descriptor. The behaviour is compatible with OS select: All
951 threads waiting for the fd return with the same status.
953 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
955 * coop-threads.c, threads.h (scm_spawn_thread): New function.
956 Can spawn a thread from application C code.
958 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
960 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
961 gh_doubles2scm): New functions.
963 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
965 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
966 commented-out version of gh_eval_str()
968 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
970 * socket.c (scm_bind): free soka after use.
972 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
974 * stime.c (tzvar): new variable.
975 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
976 avoid memory leaks when allocating.
978 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
980 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
983 * gc.c, tags.h: Doc fixes.
985 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
987 * eval.c (macro-eval!): Removed. This function was a design bug.
988 It allowed memoized code to leak out to the scheme level. Most
989 things that you could do with `macro-eval!' can be done with
992 1997-12-20 Tim Pierce <twp@skepsis.com>
994 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
995 scm_fgets now depends on ftell(3) to know how many bytes were
998 1997-12-15 Tim Pierce <twp@skepsis.com>
1000 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
1001 dealing with strings.
1003 1997-12-13 Tim Pierce <twp@skepsis.com>
1005 Make %read-line more suitable for implementing read-line efficiently.
1006 * ioext.c (scm_read_line): Strip the terminating newline from a
1007 string, and return a cons of the string and its terminator.
1009 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
1010 of the string that is read is stored in this memory location.
1011 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
1012 * genio.c, genio.h (scm_do_read_line): Update caller.
1013 * ports.h (scm_ptobfuns): Update typedef.
1014 * fports.c (scm_fptob, scm_pipob): Update struct.
1016 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1018 * filesys.c (set_element): Return file descriptor.
1019 (fill_select_type): Return the highest file descriptor.
1020 (scm_select): Tell select about the highest file descriptor. On
1021 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
1022 Therefore the extra overhead for calculating the maximum fd seems
1023 to be more than compensated. Is this correct? In any case,
1024 scm_internal_select will be much faster with this info.
1025 (scm_select, fill_select_type, set_element): Don't accept any kind
1026 of object in the file descriptor list or vector.
1028 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1030 * iselect.c (finalize_fd_sets): Bugfix.
1032 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1034 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1035 when using scm_internal_select (since we might switch to another
1038 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1040 * simpos.c (scm_system): always define: use sysmissing if not
1041 available. Check for HAVE_SYSTEM instead of _Windows (does
1042 Windows lack system or does it have an unusable one?).
1043 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1044 Let the argument be optional: if not supplied, call system(NULL).
1046 * ports.c (scm_close_port): relax the type check from OPPORTP to
1047 PORTP; closing a closed port is allowed.
1049 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1051 * fports.c (scm_fgets): Return if the last char in a chunk is
1052 newline. When fgets returns a string whose length is `size-1', it
1053 is ambiguous whether a whole line was retrieved, so we must check
1054 explicitly whether a line terminator is present.
1056 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1058 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
1059 before taking the CDR. (Thanks to Harald Meland.)
1061 * filesys.c (scm_stat): Slightly optimized.
1063 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
1065 * ports.c (scm_close_port): Make sure the port is open before
1068 * guile-snarf.in: Pass args through to gcc in a way that preserves

1073 * stacks.c (scm_frame_procedure): Reverse the logic in the return
1074 statement. (Thanks to Doug Evans for pointing this out.)
1076 1997-12-01 Tim Pierce <twp@skepsis.com>
1078 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
1080 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
1082 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
1083 errno macro expansion of this field name. (errno is a C
1084 preprocessor macro on some systems.)
1086 1997-11-29 Tim Pierce <twp@skepsis.com>
1088 * iselect.c: Doc fix.

1101 * root.h (scm_root_state): Removed the_last_stack_var.
1103 * throw.c: Added #include "fluids.h"
1104 (ss_handler): `the-last-stack' is now a fluid.
1106 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
1107 --> the_last_stack_fluid.
1109 * backtrace.c: Added #include "fluids.h"
1110 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
1111 (scm_backtrace): `the-last-stack' is now a fluid.
1113 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
1114 after scm_init_fluids.
1116 1997-11-28 Tim Pierce <twp@skepsis.com>
1118 * iselect.c: #ifdef USE_THREADS around thread-related includes.
1120 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
1121 DLSYM_ADDS_USCORE to decide whether to add an underscore.
1123 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1125 * iselect.c (coop_next_runnable_thread,
1126 coop_wait_for_runnable_thread): Disable interrupts so that no
1127 async is executed before a potential error_revive.
1128 (scm_internal_select): Disable interrupts during the parts of the
1129 code which manipulate the sleep queue and the file descriptors.
1131 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>

1136 scm_internal_select.
1137 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1138 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1139 replacement in iselect.c.
1140 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1141 coop_join): If GUILE_ISELECT enabled, use
1142 coop_wait_for_runnable_thread instead of
1143 coop_next_runnable_thread.
1144 (usleep, sleep): New replacements for system functions if
1145 GUILE_ISELECT is enabled.
1147 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1149 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1151 * filesys.c: Added #include "iselect.h". Moved FD-macros to
1152 iselect.h. Implement Scheme level `select' using
1153 scm_internal_select. (See NEWS.)
1155 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1157 * init.c: Call scm_init_iselect.
1159 * iselect.h, iselect.c: New files. Implements

1162 1997-11-27 Tim Pierce <twp@skepsis.com>
1164 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1165 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1166 and scm_must_free, since ultimately the string returned will be copied
1167 by scm_makfrom0str anyway. Also, read any characters that may have
1168 been pushed onto the port with scm_ungetc.
1169 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1170 * ioext.c (scm_read_line): Free string after Guilifying it.

1175 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
1177 * gh.h: Safely wrap prototypes for c++ usage.
1179 1997-11-25 Mark Galassi <rosalia@cygnus.com>
1181 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
1182 gh_repl (argc, argv).
1184 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1186 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1187 and to invoke scm_shell().
1188 (gh_launch_pad): took out the loading of boot-9.scm from here,
1189 since it is probably best to let the user control that. In fact,
1190 gh_repl() now invokes scm_shell() which does that.
1192 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1194 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()

1216 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1217 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1219 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1221 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1222 configure.in was changed).
1224 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
1226 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1227 * Makefile.in: Regenerated.
1229 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1231 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1232 OPORT is an `open' port, not an output port.
1234 * filesys.c (scm_close, set_element, get_element, scm_chown,
1235 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use

1240 scm_set_port_filename_x, scm_port_mode,
1241 scm_close_all_ports_except, scm_set_current_output_port,
1242 scm_set_current_error_port): Likewise
1243 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1244 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):

1247 * backtrace.c (display_backtrace_body): Likewise
1248 * fports (scm_setvbuf): Likewise

1256 Minor problems with substring-related tag changes.
1257 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1258 exactly what we want to leave in to detect substrings.
1259 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1260 * tags.h: Fix diagrams and comments describing the S tag bit;
1261 remove vestigial remarks about the D tag bit.

1263 * strings.c: Formatting tweaks.
1265 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1266 variable first; then SCHEME_LOAD_PATH, with a warning message.
1267 (scm_parse_path): New function.
1268 * script.c: Doc fixes.
1270 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>

1277 * Makefile.in: Regenerated.
1278 * scmconfig.h.in: Regenerated, after change to ../configure.
1280 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1282 * gh.h: gh_vector_set -> gh_vector_set_x
1284 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1286 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1287 with the ! -> _x mapping when going from Scheme to C.
1289 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1291 * gh.h (gh_reverse):

1309 (gh_set_cdr_x): added these routines as I go through and try to
1310 complete the picture R4RS functions that should be mirrored in the
1313 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1315 * tags.h (scm_tc7_substring): Changed the comment and code to
1316 conform with the changes below. Folks! We have suddenly two new
1317 free tc7 codes!!! Jummy, jummy!
1319 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>

1381 * gh_test_c.c (c_vector_test): some improvements on the vector
1384 * gh.h (gh_vector): this used to exist but do the wrong thing.
1385 Now it (almost) does the right thing, though it takes a list
1386 instead of the individual arguments. I need to see how it could
1388 (gh_list_to_vector): added this function as a macro. Corresponds
1389 to Scheme's (list->vector ...).

1397 (gh_make_vector): this used to be (stupidly) called gh_vector().
1398 This is the right name, since it does the same thing as the Scheme
1399 (make-vector ...) procedure.

1418 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1420 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1421 macros should by convention not test for NIMPness.)
1422 (SCM_COERCE_OPORT): Adjust indentation.
1424 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added

1435 printing: Also output hex code of vtable so that type identity
1436 will be indicated as well.
1437 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1438 Removed struct_printer_var; Removed struct-vtable-offset;
1439 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1440 vtable-offset-user): New constants.

1445 the type represented by this vtable.
1447 * print.c (scm_iprin1): Don't print arguments of macro
1448 transformers. (They are always: exp env.); Bugfix: Unmemoize
1449 transformer source with correct environment.
1451 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1453 Streamlining of call-with-dynamic-root:

1458 (cwdr_handler): New function.
1459 (scm_internal_cwdr): New function to perform the function of cwdr
1460 but take args that are more useful to C code. Also, the handler
1461 is now invoked *outside* of the new dynamic root, like the docs
1462 say. We no longer have to catch absolutely all errors, the caller
1463 is responsible for using a handler that does not throw, if he
1465 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1466 * root.h (scm_internal_cwdr): New prototype.
1468 Even more but risky streamlining:
1470 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1471 allocation of the jumpbuf of a root continuation. The changes
1472 below are controlled by it. They are now deactivated.
1473 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1474 the JMPBUF of the scm_rootcont to NULL before returning.
1476 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1477 when they are non-NULL.

1495 (scm_free_print_state): Set `revealed' field to false.
1496 (scm_iprin1): Call user supplied closure printer with
1497 scm_printer_apply. Print in the traditional way when there isn't
1498 one or when it returns #f.
1499 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1500 Accept a port/print-state pair in addition to just a port.
1501 (scm_prin1): Don't return the print_state to the pool when it has
1503 (scm_printer_apply): Set `revealed' field of print_state to true.
1504 (scm_init_print): Set scm_print_state_vtable.
1505 (print_state_fluid, print_state_fluid_num): Removed.

1512 * Makefile.in: Regenerated with automake 1.2c.
1514 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1516 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1517 was looping endlessly.
1519 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1521 * strports.c (scm_eval_string): Don't close the port.
1523 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1524 former returns a nice normal integer. (Thanks to Daniel
1527 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1529 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1530 makefile variable as a build parameter called LIBS. The
1531 build-guile program will use this, for the time being.
1532 * Makefile.in: Regenerated.
1534 Thanks to Shiro Kawai:
1535 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1536 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1539 * Makefile.in: Regenerated with automake 1.2a.
1541 * script.c (scm_compile_shell_switches): If we hit the -c or --
1542 arguments, don't set the car of (command-line) to scm_usage_name,
1543 the prettified name of the guile executable; give it the full
1544 path, the way shells usually handle $0.
1546 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1548 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1549 Scheme-level name `array-map' and renamed `serial-array-map' to
1550 `serial-array-map!'.
1552 * backtrace.c: Introduced exception handlers which now enclose
1553 `display-error' and `display-backtrace' so that error reporting
1554 won't get into infinite loops if an error occurs during displaying
1555 of the error. This can very easily happen with user supplied
1556 print call-back routines.
1558 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1560 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1561 the names `serial-array-map' and `array-map' should be removed.)
1563 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1565 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1566 Added #include "objects.h"
1568 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1569 Add #include "feature.h".
1571 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1572 (modinclude_HEADERS): Added objects.h.
1574 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1575 This test is needed at many places in the code and should be
1576 abstracted. (Motivated by the need of this test in libguiletk.)
1578 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1579 (scm_eval_string), load.c (scm_primitive_load,
1580 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1581 Use SCM_EOF_OBJECT_P.
1583 * eval.c (scm_init_eval): Add feature `delay'.
1585 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1587 * scmhob.h: Removed.
1589 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1591 * list.h (SCM_LISTn): New macros. Make list creation in C code
1592 prettier. The idea comes from STk.
1594 * sequences.h, sequences.c, append.h, append.c: Removed. These
1595 files implemented non-R4RS operations which would encourage
1596 non-portable programming style and less easy-to-read code.
1598 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1601 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1602 sequences.h, #include append.h.
1604 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1607 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1609 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1611 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1613 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1615 * eval.c: Added #include "objects.h"
1617 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1620 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1621 adjacent smob numbers.
1623 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1625 * procprop.h: Added declaration of scm_i_inner_name.
1627 * gsubr.c: New global symbol scm_i_inner_name.
1629 * debug.c (scm_procedure_name): Try procedure property
1630 `inner-name' if `name' fails.
1632 * print.c (scm_iprin1): Use scm_macro_name.
1634 * eval.c (scm_m_define): Give names to macros as well; Only the
1635 first top-level definition gives a procedure/macro a name.
1636 Otherwise confusing names can turn up in backtraces.
1637 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1638 `name'; Give names to macros as well.
1640 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1641 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1644 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1646 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
1648 (prinmacro): Removed. The code has been moved/merged into print.c
1649 in order to decrease code redundancy. We want macros to print in
1650 a way equivalent to procedures, and it would be silly to duplicate
1651 the required code. (We don't want to maintain two places.)
1652 (macrosmob): Print field is now a NULL pointer.
1654 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1655 scm_macro_transformer): New prototypes.
1656 (scm_tc16_macro): Declared.
1658 * * print.c (scm_iprin1): Added code for printing of macros. Macros
1659 are now printed in a way equivalent to procedures.
1661 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1663 * procs.h (scm_closure_p): Added declaration.
1665 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1667 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
1668 Shouldn't pass "heap" as the subr name.
1670 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1672 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
1673 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
1674 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1675 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1676 SCM_BOOL_T. Any non-false value is true.
1678 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1680 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1681 scm_gensym): Added prototypes.
1683 * symbols.c (scm_gensym): New function. This will speed up
1684 certain types of applications (such as macro systems) which
1685 generate lots of symbols.
1687 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1689 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
1691 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
1693 * unif.c (scm_shap2ra): tighten the checking of the array dimension
1694 specifier, since (2) or (2 . 3) would cause SEGV.
1695 (scm_transpose_array): more argument checking fixes.
1697 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1699 * Makefile.in: Regenerated.
1701 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1703 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
1705 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1707 * error.c, error.h (scm_error_callback): Removed (see NEWS).
1709 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
1711 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
1712 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
1715 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
1716 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1717 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
1718 scm_array_p, scm_array_rank, scm_array_dimensions,
1719 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
1720 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
1721 scm_array_prototype): Added case scm_tc7_wvect.
1723 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
1725 * errno.h: prototype for scm_strerror.
1726 * error.c (scm_strerror): new procedure.
1728 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1730 * list.c (scm_list_append_x): Allow non-pair as last argument.
1731 This is consistent with the R4RS append and is probably the
1732 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1734 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1736 * stime.h: prototype for scm_times.
1737 * stime.c (scm_times): new procedure.
1738 * ioext.c (scm_fseek): if the first argument is a file descriptor
1740 (scm_ftell): if the first argument is a file descriptor call lseek
1742 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
1743 * filesys.c (scm_chmod): if the first argument is a file descriptor,
1745 (scm_chown): if the first argument is a port or file descriptor,
1747 (scm_truncate_file): new procedure.
1748 Add DEFER/ALLOW INTS to a few other procedures.
1749 (scm_fsync): new procedure.
1750 (scm_open_fdes): new procedure.
1751 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
1753 (scm_fcntl): the first argument can now be a file descriptor. The
1754 third argument is now optional.
1756 * posix.c (scm_execl, scm_execlp): make the filename argument
1757 compulsory, since omitting it causes SEGV.
1758 (scm_sync): return unspecified instead of #f.
1759 (scm_execle): new procedure.
1760 (environ_list_to_c): new procedure.
1761 (scm_environ): use environ_list_to_c. disable interrupts.
1762 (scm_convert_exec_args): take pos and subr arguments and
1763 improve error checking.
1765 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1767 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1768 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1769 argument to SCM_ASSERT. Furthermore, the name of the function
1770 should be passed as first argument when signalling
1771 SCM_WNA. (Thanks to Thomas Morgan)
1773 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1774 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1775 dispatches on the number of actual args has a default case
1776 reporting an internal error. This is a vestige from a version
1777 that mallocated a SCM vector to hold the arguments. In the
1778 current version this check is too late: if it ever happens we will
1779 have already overstepped the bounds of the array.
1781 Also, the patch [...] adds a check for too many actual arguments."
1783 mdj: Removed check for "internal programming error".
1785 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1787 * gh_io.c (gh_write): New function.
1789 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
1790 throw.c (scm_internal_stack_catch): New sibling to the other catch
1791 functions. Code moved from gh_eval.c.
1792 throw.h: Added header.
1793 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
1794 scm_internal_stack_catch.
1796 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1798 * ioext.h: fix up prototypes.
1799 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
1800 Scheme name is now dup->fdes.
1801 (scm_dup_to_fdes): make the second argument optional and
1802 fold in the functionality of scm_primitive_dup.
1803 (scm_primitive_dup): deleted.
1805 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1807 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
1808 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
1809 ultrix are defined. Use setvbuf instead of setbuf.
1810 (scm_setvbuf): new procedure.
1811 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
1812 (scm_setfileno): moved from ioext.c.
1813 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
1814 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
1816 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1818 * fluids.c (scm_fluid_p): New function.
1819 * fluids.h (scm_fluid_p): New prototype.

1823 * print.c (scm_iprin1): Enter printed structures into the print
1824 state as nested data while they are printed.
1825 (print_state_fluid, print_state_fluid_num): New variables.
1826 (scm_init_print): Initialize them.
1827 (scm_iprin): If print_state_fluid carries a print_state, use that
1828 instead of creating a new one.
1829 (scm_printer_apply, apply_stub, struct apply_data): New
1830 definitions to help with calling printer functions written in
1832 * print.h (scm_printer_apply): New prototype.
1834 * struct.c (scm_print_struct): Use scm_printer_apply to call the
1835 user defined struct printer.
1837 * dynwind.c (scm_dowinds): Handle fluids on the wind list.
1838 * fluids.h (scm_internal_with_fluids, scm_with_fluids,

1843 Fri Jul 25 12:05:46 1997 Marius Vollmer <mvo@zagadka.ping.de>
1845 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
1846 SCM_ASSERT: arg comes before pos.
1848 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1850 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
1851 to a list of length zero correctly.
1853 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1855 Supply an `fgets' method for port objects to do fast line i/o.
1856 * ioext.c (scm_read_line): New function.
1857 * genio.c (scm_gen_read_line): New function.
1858 * fports.c (scm_fgets): New function.
1859 (scm_fptob, scm_pipob): Add scm_fgets method.

1867 Mon Jul 21 04:03:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1869 * ioext.h: removed scm_duplicate_port prototype.
1871 * ioext.c (scm_primitive_dup2): return the new file descriptor
1872 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
1874 (scm_fdopen): bug fix: don't try to make port unbuffered until its
1875 stream has been set.
1876 (scm_duplicate_port): deleted, there's now an implementation in
1878 (scm_primitive_dup2): do nothing if newfd == oldfd.
1880 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
1882 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
1885 * ioext.h: new prototypes.
1886 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
1888 * fluids.c (next_fluid_num): don't do
1889 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
1891 * ports.h: prototypes too.
1892 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
1894 * fports.h: prototype too.
1895 * fports.c (scm_evict_ports): moved from ioext.c.
1897 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
1899 * ports.c (scm_close_port): return a boolean instead of unspecified.
1900 throw an error if an error other than EBADF occurs.
1902 * filesys.h: scm_close prototype.
1903 * filesys.c (scm_close): new procedure, can close file descriptors
1904 and ports (scsh compatible).
1906 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
1909 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
1911 * fluids.c, fluid.h: New files.
1912 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
1913 (modinclude_HEADERS): Added "fluids.h"
1915 * init.c: Include "fluids.h". (scm_boot_guile_1): Added call to
1916 scm_init_fluids to initialize the fluid machine.
1917 (scm_start_stack): Initialize the fluids of the first root with
1918 scm_make_initial_fluids.

1921 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
1922 (scm_make_root): Call scm_copy_fluids to make fluid bindings
1923 unique for the new root when it has a parent.
1925 * smob.h: Include "libguile/print.h" to make scm_print_state
1928 * dynl.c (free_dynl_obj): New function to free the dynamic object
1929 data. (dynl_smob): Use it.
1930 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
1931 the dynamic object data below the linking of the object to avoid
1932 memory leak when the linking code throws an error. Now the code
1933 leaks a whole dynamically linked library when must_malloc throws,
1934 but that should be much less likely.
1936 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
1938 Changes to compile under gnu-win32, from Marcus Daniels:
1939 * stime.c (tzset): If tzset isn't provided, make it a NOP.
1940 (scm_localtime): Change SCM_EOF to SCM_EOL.
1941 (scm_mktime): Likewise.
1942 * socket.c: Don't include sys/un.h unless autoconf tells
1943 us Unix domain sockets are available.
1944 (scm_fill_sockaddr): Ignore Unix domain code.
1945 (scm_addr_vector): Likewise.
1946 (scm_init_addr_buffer): Likewise.
1947 (scm_socketpair): Don't include unless socketpair was

1950 * scmsigs.c (scm_pause): Don't include unless pause was found
1952 * posix.c (scm_getgroups): Don't include unless support function
1953 was found during autoconf (in this case, getgroups).
1954 (scm_setpwent): For setpwent.
1955 (scm_setegid): For setegid.
1956 * net_db.c (scm_inet_netof): Don't include unless support
1957 function was found during autoconf (in this case, inet_netof).
1958 (scm_lnaof): For inet_lnaof.
1959 (scm_inet_makeaddr): For inet_makeaddr.
1960 (scm_getnet): For getnetent, getnetbyname, getnetbyaddr.

1971 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
1972 scm_misc_error, not SCM_EOF.
1974 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
1975 arguments for formatting the error message, not SCM_BOOL_F. I
1976 think this is left over from the (eq? '() #f) days.
1978 * read.c (recsexpr): Give this a dummy definition if
1979 DEBUG_EXTENSIONS isn't #defined.
1981 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
1983 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
1986 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>

1991 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
1993 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
1994 alloca.lo will be included in @LIBLOBJS@. Something better than
1995 this should be possible.
1996 * Makefile.in: Regenerated.
1998 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2000 * simpos.h: prototype for scm_primitive_exit.
2001 * simpos.c (scm_primitive_exit): new procedure, terminates the
2002 process without unwinding the stack.
2004 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
2006 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
2007 argument and logior its components together, so the user doesn't
2008 have to do this explicitly. Also, if regexp/basic is supplied, then
2009 turn off REG_EXTENDED.
2010 (scm_init_regex_posix): New regexp/basic symbol.
2011 (REG_BASIC): #define this if it is not already present.
2013 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2015 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
2016 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
2017 (CLEANFILES): New target, clean versiondat.h, libpath.h.
2018 (DISTCLEANFILES): New target, clean *.x.
2019 * Makefile.in: Regenerated.
2021 Tue Jun 24 00:29:07 1997 Jim Blandy <jimb@floss.red-bean.com>
2023 * script.c (scm_compile_shell_switches): Add 1997 to copyright
2024 years in usage message.
2026 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
2027 * Makefile.in: Regenerated.
2029 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
2030 flag; I don't think we support it.
2031 (scm_make_regexp): Make sure the user doesn't pass the
2034 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
2036 (scm_init_regex_posix): Define constants for the REG_mumble flags;
2037 name them according to the SCSH convention: regexp/mumble.
2039 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
2041 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
2043 * Makefile.am (libpath.h): Include the values of all the standard
2044 Makefile directory variables. Print a message, but don't print
2046 (versiondat.h): Print a message, but don't print all the commands.
2047 * load.c: #include "alist.h".
2048 (init_build_info): New function.
2049 (scm_init_load): Call it.
2050 * Makefile.in: Regenerated.
2052 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
2054 * root.c: Establish a reliable catch-all handler for the new root.
2055 After all the Scheme handler function might signal an error too,
2056 and we don't want to lose that.
2057 (cwdr_inner_body): Renamed from cwdr_body.
2058 (cwdr_outer_body): New function, to establish the user's handler,
2059 and pass control to cwdr_inner_body.
2060 (cwdr): Establish the reliable catch-all handler here, and pass
2061 control to cwdr_outer_body.
2062 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
2063 the user's handler through to cwdr_outer_body.
2064 * throw.c (scm_handle_by_message): Move guts into....
2065 (handler_message): New static function.
2066 (scm_handle_by_message_noexit): New function.
2067 * throw.h (scm_handle_by_message_noexit): New prototype.
2069 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
2070 across this. Only works on GCC. Otherwise, we hope for the best.
2071 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2072 the feeling that real thread systems will not need this...
2074 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2076 Try to detect when people are using one version of libguile and a
2077 different version of ice-9. People have been skewing things and
2078 sending in bug reports.
2079 * Makefile.am (versiondat.h): New file to generate.
2080 * version.c: #include "versiondat.h", to get version info.
2081 (scm_libguile_config_stamp): New function.
2082 * script.c: #include "version.h".
2083 (scm_compile_switches): Call scm_version to get version number.
2084 * scmconfig.h.in, Makefile.in: Regenerated.
2085 * Makefile.in: Regenerated.
2087 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
2088 primitive definitions under their Scheme names.
2090 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2091 1:2. Helps avoid confusion between installed and uninstalled libs.
2093 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2096 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2097 backslash from definition; this should be used like: GDB_INTERFACE;
2099 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2101 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
2102 new port unbuffered until its stream has been set.
2104 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2106 * ports.h: new prototype.
2107 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
2109 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
2111 Make things compile neatly under Sun's C compiler.
2112 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
2113 * extchrs.c (xmbtowc): Make the second arg a normal char, not
2114 unsigned, because that's what the ANSI function takes.
2115 * extchrs.h (xmbtowc): Corresponding change to prototype.
2116 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2118 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2119 argument plain char *.
2120 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2122 * tag.c (scm_tag): Remove unreachable statement.
2123 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2124 top of the word, it should be unsigned.
2126 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2127 is defined, to avoid warnings; it's only used in the
2128 conflict-checking code. Which might go away anyway.
2129 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2130 conditionals; put the label definition in an #if too, to stifle
2133 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2134 ChangeLog-threads in the distribution.
2135 * Makefile.in: Regenerated.
2137 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2139 * guile-snarf.in: Changed regexp to support CPPs that insert
2140 whitespace between lexical tokens (which munges the `%%%' snarf
2143 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2145 * load.c (scm_init_load_path): Append $(datadir)/guile to
2146 %load-path, so modules do not have to be installed in Guile's
2147 current version directory.
2149 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2151 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2152 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2153 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2154 call the sysdep functions with deferred ints.
2155 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2156 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2157 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2160 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2163 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2165 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2167 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2169 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2172 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2174 * eval.c (scm_lookupcar1): New procedure to cope with a race
2175 condition during lookup (when using threads).
2176 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2177 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2180 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2182 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2183 supplied. (Change from Tim Pierce.)
2185 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2187 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2188 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2189 default and not `()'. `#f' is the canonical non-value in Scheme,
2192 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2194 * struct.c (struct_printer): New variable that holds a handle on
2195 the Scheme variable *struct-printer*. This variable can be set by
2196 Scheme code to override the printing of structures.
2197 (scm_print_struct): If struct_printer is set, call it. If it is
2198 not set, or returns #f, print the structure in the old fashion.
2199 Include "eval.h" for scm_apply.
2201 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2203 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2204 scm_struct_i_n_words to get the number of fields, not
2205 -scm_struct_n_extra_words.
2207 On the route to fancier struct printing:
2208 * struct.c (scm_print_struct): New function to print a structure.
2209 Include "genio.h" to support it. This function doesn't do
2210 anything interesting right now, but I think it should be here
2212 * struct.h: Include "print.h" and add prototype for
2214 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2215 print structures ourself.
2217 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2219 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2220 before applying the handler in case it doesn't return.
2222 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2224 * scmsigs.h, async.h: updated.
2226 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2229 * posix.c (scm_uname): interpret only negative values as an error.
2230 Solaris normally returns a positive value.
2232 * script.c (scm_compile_shell_switches): if we are not going into
2233 an interactive repl, set scm_mask_ints to zero so that asyncs can
2236 * simpos.c (scm_system): don't ignore/unignore signals around
2239 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2242 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2243 done in boot-9.scm instead.
2245 * scmsigs.c, async.c: Major rewriting of signal handling code.
2246 (scm_sigaction): new procedure.
2247 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2249 (scm_raise): return unspecified, throw error on failure.
2251 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2253 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2254 feature, to help boot-9.scm decide whether to import the regex
2257 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2259 * eval.c: Include scmconfig.h at the beginning of the file so that
2260 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2263 * regex-posix.c: #include "_scm.h" before conditionally #including
2264 <regex.h>; the former defines HAVE_REGCOMP.
2266 * regex-posix.c: #include <regex.h> conditionally, so the file is
2267 CPP'able (for dependency scanning) even on systems that don't have
2270 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2272 Add new R4RS-compliant syntax for keywords.
2273 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2274 regardless of the setting of the `keywords' read option.
2275 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2276 can be re-read no matter what the setting of the `keywords' read
2279 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2281 Add support for POSIX regular expressions.
2283 * regex-posix.c, regex-posix.h: New files. (Some code
2284 is taken liberally from rx/rgx.c in the old Guile dist.)
2286 * init.c: Include regex-posix.h.
2287 (scm_boot_guile_1): Call scm_init_regex_posix.
2289 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2290 Add regex-posix.[ch] sources.
2291 * Makefile.in: Regenerated.
2293 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2294 to do this automatically? It didn't for me, bleh.)
2296 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2298 * fports.c (print_pipe_port): New function.
2299 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2300 latter doesn't even take the right arguments.
2302 * Makefile.am: Increment shared lib revision number. I think
2303 sometimes the uninstalled Guile finds the installed shared lib;
2304 Gord says doing this might help. As things turned out, I can't
2305 say whether it does.
2306 * Makefile.in: Regenerated.
2308 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2309 passing it as the closure argument to scm_boot_guile. (Bill
2312 * ports.c (print_void_port, putc_void_port, puts_void_port,
2313 write_void_port, flush_void_port, getc_void_port, close_void_port,
2314 noop0): Use ANSI prototypes instead of K&R declarations, so the
2315 initialization of void_port_ptob gets aggressively type-checked.
2316 Fix arguments of print_void_port and write_void_port. (Bill

2350 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2352 * script.c (scm_find_executable): Use prototype-style definition
2353 here; apparently it's not quite right to have const in a prototype
2354 and then use a K&R declaration. I wonder if stuff like this will
2355 go away if we compile with -Wrequire-prototypes, or whatever that
2356 is... (Bernard URBAN)
2358 * scmhob.h: New text from Bernard URBAN.
2360 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2362 * script.c: Don't #define const on hpux. Configure takes care of
2363 this. (Thanks to Larry Schwimmer.)
2365 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2366 decide whether to #include <unistd.h>, instead of listing a bunch
2367 of systems. Don't #include stdio twice. Removed dyked-out
2368 definition of scm_find_impl_file.
2370 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2372 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2373 library version info to 1:0.
2374 * Makefile.in: Regenerated.

2380 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2381 throw.c: Update copyright years; these files have been worked on
2382 significantly in 1997, but only had copyright years for 1996.
2383 Also, change name of copyright holder on some from Mikael
2384 Djurfeldt to Free Software Foundation; he has signed papers
2385 assigning the changes to the FSF.
2387 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2388 reason not to give the user the option.
2390 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2391 Return #f on end-of-file when scanning table (i.e. when called
2392 with no arguments). Try to catch errors, when we can.
2393 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2395 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2396 external declarations. These are useful.
2398 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2400 * posix.c: don't include <sys/select.h> or define macros for
2401 select, since they were not used in this file.
2403 * filesys.c (scm_select): make the fifth parameter microseconds,
2404 not milliseconds. let the fourth parameter be either a real value
2405 or an integer or #f. The first, second and third arguments can
2406 now be vectors: the type of the corresponding return set will be
2408 (set_element, get_element): new static procedures.
2410 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2412 * strports.c (scm_eval_string): New function.
2413 (scm_eval_0str): Trivially re-implemented in terms of
2415 * strports.h (scm_eval_string): New extern decl.
2417 * net_db.c (h_errno): Add extern decl for this.
2419 * fports.c (local_pclose): New function.
2420 (scm_pipob): Use it in the initializer here.
2423 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2424 Use a meaningful error message when signalling an error. For
2425 this, scm_gethost must check h_errno rather than errno.
2427 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2429 * Makefile.in: Regenerated, using automake-1.1p.
2431 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2433 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2434 not SCM_UNSPECIFIED.
2436 * script.c (scm_compile_shell_switches): don't append (quit) if
2438 (scm_shell): call scm_exit_status and exit on the result of the
2441 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2443 Ensure that shared substrings are handled properly when passed to
2444 a system call or other foreign function. Many thanks to Tim
2446 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2447 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2448 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2449 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

2452 (scm_display_error_message): use RO macros when strings may be RO.
2453 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
2454 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
2455 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
2456 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
2457 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
2458 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
2459 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
2460 scm_strftime), vports.c (scm_make_soft_port): use
2461 SCM_COERCE_SUBSTR to make sure shared substrings are

2466 * error.c (scm_error): Add newline to error message.
2468 * init.c (scm_init_standard_ports): Doc fix.
2470 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2472 * dynl-shl.c: Completely replaced with new code from Bernard
2475 * script.c (scm_ice_9_already_loaded): New variable.
2476 (scm_compile_shell_switches): Use it.
2478 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2480 * filesys.c (scm_input_waiting_p): add missing third argument to
2483 * stime.c (scm_localtime): copy the result of localtime before
2484 calling gmtime in case they share a buffer.
2485 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2488 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2490 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2492 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2494 * Makefile.am (check-local): New target, which causes 'make check'
2495 to run gh_test_c and gh_test_repl, with some trivial input.
2496 * Makefile.in: Rgnrtd.
2498 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2500 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2503 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2505 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2506 sure how this was supposed to work.
2507 (scm_async_click): don't send SCM_TICK_SIGNAL.
2508 (scm_init_async): don't initialize %tick-thunk.
2510 * the following change doesn't affect the Scheme interface:
2511 gc-thunk is called at the end of garbage collection. however it's
2512 no longer implemented by pretending it's a signal.
2514 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2515 system async corresponding to scm_gc_thunk.
2516 * async.h: declare scm_gc_async.
2517 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2518 gc-thunk directly, instead of going through a signal handler.
2519 (scm_gc_async): new variable, points to the GC system-async.
2520 (scm_init_async): save the GC async as scm_gc_async instead
2521 of using system_signal_asyncs.
2522 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2524 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2526 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2527 Don't screw up if we're interrupted.
2528 * Makefile.in: Regeneradet.
2530 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2532 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2534 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2535 we're not using AM_INIT_GUILE_MODULE any more.
2536 * Makefile.in: Reneregated.
2538 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2540 Functions for finding variable bindings, grace à Tim Pierce.
2541 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2542 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2544 Get 'make dist' to work again.
2545 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2546 * Makefile.in: Regenerated, like a surry without a fringe on top.
2548 Changes for reduced Guile distribution: one configure script,
2550 * configure.in, configure: Removed.
2551 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2552 real configure script lives.
2553 * Makefile.in, scmconfig.h.in: Regenerated.
2555 * init.c: #include "script.h", to get prototype for script.c's
2558 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2560 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2561 scm_must_malloc, not raw malloc.
2563 * script.c (scm_compile_shell_switches): Dyke out debugging output
2566 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2568 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2570 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2571 system has them. Hope this is safe. Previously
2572 sys/timeb.h was included if HAVE_FTIME was defined or if
2573 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2574 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2576 * ioext.c (scm_setfileno): add missing third argument to
2577 scm_misc_error call.
2579 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2581 * eq.c (scm_equal_p): Correctly compare strings of different
2582 varieties. (Thanks to Tim Pierce.)
2584 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2586 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2587 #! block comment must occur on a line all by itself.
2589 Move most of the guts of shell command processing into libguile,
2590 so guile.c can be very small (and eventuallly auto-generated. (I
2591 mean, generated mechanically, not self-generated. Hmm.))
2592 * guile.c, script.c, script.h: New source files.
2593 * init.c (scm_boot_guile_1): Call scm_init_script.
2594 * libguile.h: #include "script.h".
2595 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2596 targets, for new executable.
2597 (libguile_la_SOURCES): Mention script.c.
2598 (modinclude_HEADERS): Add script.h.
2599 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2600 not dynamic linking is enabled. This is because we're generating
2601 executables now. Move CY_AC_WITH_THREADS call after those, so the
2602 values of cy_cv_threads_libs captures the libs chosen above.
2603 * Makefile.in, configure, aclocal.m4: Regenerated.
2605 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2606 We don't maintain this interface any more, and it just confuses
2609 * alloca.c: #include <scmconfig.h>, not <config.h>.
2610 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2611 it'll get included in disties.
2613 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2615 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2616 be distributed, because they confuse people.
2617 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2619 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2621 * configure.in: check for presence of gethostent (not present on
2622 OpenBSD by default).
2623 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2624 * configure, scmconfig.h.in: Regenerated.
2626 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2628 * backtrace.c (scm_backtrace): Split message string across
2629 newlines properly. GCC is more tolerant of this than other
2632 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
2634 Merge threads directory into libguile.
2635 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
2636 threads.h: New source files.
2637 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
2638 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2640 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2641 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2642 coop-threads.c.cygnus, coop-threads.h.cygnus.
2643 * configure.in: If we're using threads, include threads.o in
2645 * _scm.h, libguile.h: threads.h lives in this directory now.
2646 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2647 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2648 currently used, but brought along for information's sake.
2649 * ChangeLog-threads: log from old 'threads' directory.
2650 * Makefile.in, configure: Rebuilt.
2652 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2654 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2657 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2659 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2661 Merge GH interface library into libguile.
2662 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
2663 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2664 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2665 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2667 (EXTRA_libguile_la_SOURCES): ... here.
2668 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2669 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2670 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2671 New variables, describing how to build the gh test programs.
2672 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2673 build the test programs, and we probably should have been linking
2674 libguile.la against them all along, to support AIX shared libs.
2675 Add cflags for threads to CFLAGS; add libs for threads to new
2676 variable THREAD_LIBS, used in Makefile.am.
2677 * ChangeLog-gh: log from old `gh' subdirectory.
2678 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2680 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2682 * acconfig.h: Undo change of Apr 9; including the definition of
2683 PACKAGE in the guile headers conflicts with applications' own
2685 * scmconfig.h.in: Regenerated.
2687 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

2691 * filesys.h: Added prototype.
2693 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
2694 when PROC is receiving no arguments.
2696 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2698 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2699 have S_IFSOCK. This is the case under Ultrix.
2701 * posix.c (scm_status_exit_val, scm_status_exit_val,
2702 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2703 Ultrix versions of WIFSTOPPED, etc., which assume that their
2704 arguments are lvalues (hmm).
2706 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2708 * eval.c: Doc fixes.
2710 * throw.c: Doc fixes; rearranged.
2712 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
2714 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
2716 * acconfig.h: Added entry for PACKAGE.
2717 * scmconfig.h.in: Regenerated.
2719 Changes to work with automake-1.1n, which has better libtool support.
2720 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2721 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
2723 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
2725 * Makefile.in: Rebuild.
2727 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2729 * stime.c (scm_mktime): take an optional zone argument.
2730 (scm_localtime): check putenv return value.
2731 (scm_strftime, scm_strptime): moved from posix.c. move #include
2733 stime.h, posix.h: update prototypes.
2734 (bdtime2c, setzone, restorezone): new static procedures.
2735 (scm_mktime, scm_strftime): use them.
2736 (scm_strftime): don't call mktime before strftime. Use
2737 filltime for return value.
2738 (filltime): convert NULL zname to #f.
2739 (scm_strptime): return a count of characters consumed, not
2740 the remaining string.
2742 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2744 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
2745 (scm_mktime): likewise.
2747 Uncomment localtime and mktime.
2749 * configure.in: add AC_STRUCT_TIMEZONE.
2751 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2753 * stime.c (scm_init_stime): don't define ticks/sec.
2754 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2755 return value problem and is still portable.)
2757 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2759 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2760 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2761 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2762 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2763 cpp_err_symbols.c): Corresponding changes.
2764 * Makefile.in: Regenerated.
2766 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2768 * posix.c (scm_putenv): don't check HAVE_PUTENV.
2769 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
2770 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
2771 * putenv.c: new file, from sh-utils 1.12.
2773 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2774 since allocation isn't for Scheme objects.
2775 (scm_putenv): copy strings before placing in the environment.
2777 * stime.c (scm_current_time): throw an error if time returns -1,
2778 instead of returning #f.
2779 (scm_get_internal_real_time, scm_get_internal_real_time): use
2780 scm_long2num for return value instead of SCM_MAKINUM.
2782 * stime.h: prototypes updated.
2784 * stime.c (scm_time_in_msec): apparently unused, deleted.
2786 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2788 * configure.in: check for gettimeofday.
2790 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2791 which may be more usefully portable than a gettimeofday interface.
2793 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2795 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
2797 * Makefile.in: Regenerated.
2799 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2801 * stime.c (filltime): recovered static procedure.
2802 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
2805 * posix.h: add prototype for scm_close_pipe, remove prototypes for
2806 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2808 * posix.c (scm_mknod): split the mode argument into type and perms
2809 arguments, like the extra fields returned by stat.
2811 * fports.c (scm_pipob): set the close, free and print procedures.
2812 (scm_close_pipe): new procedure.
2814 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2815 define them in boot-9.scm
2817 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2819 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
2820 wan't defined. Don't include fd.h.
2822 * Previously fd.h was regenerated whenever configure was run,
2823 forcing a couple of files to be recompiled.
2825 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
2826 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
2827 Check for _fileno as well as _file.
2829 * ioext.c: don't fd.h.
2830 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
2833 * Change the stratigy for getting information about errno
2834 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
2835 generating lists of symbols during the build process, which will
2836 not always work, include comprehensive lists in the distribution.
2837 To help keep the lists up to date, the "check_signals" and
2838 "check_errnos" make targets can be used.
2840 * configure.in: don't check for a command to extract errno codes.
2841 * Makefile.am: update file lists, remove errnos.list and errnos.c
2842 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
2843 check_errnos targets.
2844 (CLEANFILES): remove errnos.c and errnos.list, add
2845 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
2846 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
2847 * errnos.default: deleted.
2848 * cpp_signal.c: new file.
2849 * cpp_errno.c: renamed from errnos_get.c.
2850 * cpp_err_symbols, cpp_sig_symbols: new files.
2851 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
2852 * error.c (scm_init_error): #include cpp_err_symbols instead of
2854 * posix.c (scm_init_posix): don't intern signal symbols. #include
2857 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
2859 * strop.c (scm_i_index): allow the lower bound to be equal to the
2860 length of the string, so a null string doesn't always give an error.
2862 * posix.h: new prototypes.
2863 * posix.c (scm_status_exit_val, scm_status_term_sig,
2864 scm_status_stop_sig): new functions, as in scsh. They break down
2865 process status values as returned by waitpid.
2867 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
2869 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
2870 configure doesn't know about it.
2872 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2874 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
2876 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
2877 which defines C variables with global linkage.
2879 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2881 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
2884 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
2886 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
2887 has time to check why this doesn't work well with continuations.
2889 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
2891 * Fix shell syntax error; some shells won't tolerate
2892 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
2894 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2896 * posix.c (scm_uname): throw an error if uname fails instead
2899 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
2901 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
2904 * async.c (scm_ints_disabled): definition moved from error.c.
2906 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2908 * acconfig.h: Removed PACKAGE.
2910 * scmconfig.h.in: Regenerated.
2912 * snarf.h: g++ says it's non-portable not to specify the first
2913 argument in a varargs declaration. I introduced the first
2914 argument by using preprocessor conditionals.
2916 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
2918 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
2919 (scm_freopen): use RO string macros for filename and modes.
2920 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
2922 * posix.c (scm_getgrgid): simplify conversion of name to C string.
2923 (scm_mknod): use RO string macros for path.
2925 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
2926 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
2928 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2929 use SCM_ROSTRINGP and SCM_ROCHARS.
2931 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2933 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
2936 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
2937 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
2938 support for byte vectors.
2940 * print.c (scm_iprin1): Limit number of vector elements printed
2941 according to pstate->length.
2943 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2945 * backtrace.c (scm_display_error_message): don't segv if message
2948 * error.h: prototype for scm_error_scm.
2950 * error.c (scm_error_scm): new procedure, reimplements scm-error
2951 in C and uses scm_error.
2953 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2955 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
2956 pointer to the Scheme variable read-hash-procedures and intern it
2957 in scm_init_read. Modify scm_read_hash_extend and
2958 scm_get_hash_procedure to use the pointer.
2960 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2962 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
2963 (SCM_KEYWORD_STYLE): defined.
2965 * read.c (scm_read_opts): add a keywords option. This isn't a
2966 boolean option, in case someone wants to add support for DSSSL
2968 Setup scm_keyword_prefix symbol.
2969 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
2971 I've left keyword support disabled by default, since it doesn't
2972 seem to break the module system and it gives R4RS standard behaviour.
2973 It can be reactivated with (read-set! keywords 'prefix).
2975 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2977 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
2978 before constructing arbiter.
2980 * eval.c (scm_m_define): Bugfix: Check that the object is a
2981 closure before setting the procedure property!
2983 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
2985 * ports.c: Removed `ungetc-char-ready?'.
2987 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
2989 * read.c (scm_init_read): intitialise scm_read_hash_procedures
2990 (idea from Mikael: make it a pair so scm_permanent object only
2992 (scm_read_hash_extend): don't call scm_permanent_object.
2993 (ideas from Mikael): if chr is already in the list, replace its
2994 procedure instead of appending it again. If proc is #f, remove
2996 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
2998 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
3000 * gdbint.c (gdb_read): update scm_lreadr usage.
3002 * load.h: update prototypes.
3004 * load.c (scm_primitive_load, scm_read_and_eval_x,
3005 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
3007 * read.h: add prototype for scm_read_hash_extend. Change args for
3010 * read.c (scm_read_hash_procedures): new variable.
3011 (scm_read_hash_extend): new procedure.
3012 (scm_get_hash_procedure): new procedure.
3013 (scm_lreadr): use scm_get_hash_procedure instead of an argument
3014 for extended # processing.
3015 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
3016 scm_read_token): remove case_i, sharp arguments. Change callers.
3018 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
3020 * read.h (SCM_N_READ_OPTIONS): increase to 3.
3021 (SCM_CASE_INSENSITIVE_P): define.
3023 * read.c: add case-insensitive option to scm_read_opts.
3024 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
3025 to determine whether to convert symbol case.
3026 (default_case_i): definition removed.
3027 * read.c (scm_read_token): if case_i, downcase ic before doing
3030 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3032 * configure.in: Added configuration option `guile-debug'.
3033 Configure with --enable-guile-debug if you want a bunch of extra
3034 functions used for debugging when developing Guile.
3036 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3038 * procs.c (make-cclo): New undocumented debugging procedure: Make
3039 compiled closure with internal procedure PROC and length LENGTH.
3040 Only compiled if GUILE_DEBUG is defined.
3042 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3044 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3046 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3048 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3049 with 3 or more args internally to the evaluator.
3051 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3053 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3054 with 3 or more args internally to the evaluator. This is mainly
3055 because we don't want to pass entry and exit points of the
3056 debug support twice, but it also seems to increase the speed of
3057 the evaluator for such calls (e. g. (+ 1 2 3)).
3059 * backtrace.c (scm_display_application): New procedure:
3060 display-application; Set fancy printing parameters individually
3061 for different types of display (backtrace, error, application).
3062 (These should of course be customizable!)
3064 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3065 clear the CHECK-flags.
3067 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3069 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3071 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3073 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3074 from pairs with a GLOC in the car.
3076 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3077 otherwise `symbol-hash' will behave badly.
3078 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3079 we get segmentation fault!
3081 * symbols.c: Added #include "weaks.h". New functions:
3082 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3083 moved to an extraneous library when we split libguile.)
3085 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3087 * filesys.c (scm_stat): stat now takes fport arguments too as
3088 documented in the manual.
3090 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3092 * debug.c (scm_single_step): Bugfix: Call continuation with
3093 scm_call_continuation instead of throwing to it.
3095 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3097 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3098 argument wasn't declared to be optional.
3100 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3102 * stime.c (scm_init_stime): Add feature "current-time".
3104 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3106 * throw.h: prototype for scm_exit_status.
3107 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3108 args to derive an exit status. Allows (quit) to work from a
3110 (scm_exit_status): new function.
3113 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3115 * eval.c (scm_deval): Removed some old code.
3116 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3118 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3121 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3124 * procs.c: Introduce the existent C function scm_thunk_p at the
3125 Scheme level as well.
3127 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3129 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3130 used from C to easily lookup the value of a symbol in the current
3133 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3135 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3136 scm_init_unif in this file. This will also fix a previous problem
3139 * configure.in: Added AM_MAINTAINER_MODE
3141 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3143 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3146 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3148 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3149 source files that are not always included in libguile but should
3150 have their dependencies calculated by automake. This variable is
3151 recognized by automake, no further magic is needed.
3152 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3153 to deal exclusively with *.lo files, as it seems. The *.o files
3154 are built automatically when the corresponding *.lo file gets
3157 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3159 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3162 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3164 * unif.c (scm_array_set_x): minor change to argument error checking.
3166 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3168 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3169 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3170 They should only be included in the library at configure.in's
3172 (libguile_la_LDADD): Include the appropriate .lo files here.
3173 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3174 so we know when to build them (and their .lo bretheren).
3175 * configure.in (LIBLOBJS): New substituted variable. We let
3176 configure decide which .o files to include in LIBOBJS, and then
3177 put the corresponding list of .lo files in LIBLOBJS. The latter
3178 is what we pass to libtool.
3179 * Makefile.in, configure: regenerated.
3181 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3183 * symbols.c (scm_sysintern0): New function. Contains the core of
3184 old scm_sysintern but doesn't take a second value argument.
3185 (scm_sysintern): Now uses scm_sysintern0.
3186 (scm_sysintern_no_module_lookup): Renamed to
3187 scm_sysintern0_no_module_lookup and doesn't take a second value
3188 argument any longer.
3190 * symbols.h (scm_sysintern0: Added declaration.
3192 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3193 scm_sysintern when interning option keys. Otherwise we risk
3194 destroying the values of already interned variables.
3196 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3197 scheme-level boolean (use SCM_NFALSEP).
3199 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3201 (scm_backtrace): New function. (C version of old function from
3202 boot-9.scm) Motivation: Make it possible to display backtraces
3203 without depending on boot-9.scm. (I'm uncertain if this
3204 motivation is good enough...)
3206 * root.h (scm_root_state): Add member the_last_stack_var.
3207 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3209 * root.c (mark_root): Mark scm_the_last_stack_var.
3211 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3214 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3216 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3217 1. mark_lazy_catch didn't mark the smob.
3218 2. Both functions above have standard variants:
3219 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3220 free_lazy_catch --> scm_free0.
3222 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3224 * throw.c (scm_internal_lazy_catch): New function.
3225 (scm_lazy_catch): Rewritten to use it.
3226 (scm_ithrow): Handle the new lazy catch representation.
3227 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3228 that doesn't have a jmpbuf is a lazy catch clause.
3229 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3230 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3231 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3233 (scm_init_throw): Register the new lazy-catch smob type.
3234 * throw.h (scm_internal_lazy_catch): decl for new function.
3236 * throw.c (scm_internal_catch): Doc fixes.
3238 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3239 configure.in. Including this might cause problems if applications
3240 that link against libguile include their own copies of alloca, but
3241 if they're using autoconf, they should be adding libguile to LIBS
3242 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3243 the copy in libguile, and things will be okay. (I think.)
3245 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3247 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3249 strop.h: move prototypes too.
3251 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3253 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3256 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3257 etc. I deleted them from filesys.c long ago, but didn't
3258 notice they were here too (although ineffective since
3259 sys/stat.h wasn't included).
3261 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3263 * eval.c: Don't define alloca in GCC case. gcc will automatically
3264 use __builtin_alloca if appropriate.
3266 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3268 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3269 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3270 that values of automatic variables are preserved. See comments
3271 for safe_setjmp for details.
3273 Change from Thomas Morgan:
3274 * variable.c: Include eq.h.
3275 (var_equal): New function.
3276 (variable_smob): Use var_equal as the discriminator for variables.
3278 * throw.c (s_throw): Remove extraneous declaration.
3280 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3281 * eval.c: Add necessary CPP cruft to support that.
3282 * configure, Makefile.in, scmconfig.h.in: regenerated.
3284 Change from Thomas Morgan:
3285 * procprop.c (scm_procedure_properties): Convert the Scheme
3286 boolean returned by scm_procedure_p into a C boolean before using
3287 it as a condition for SCM_ASSERT.
3288 (scm_procedure_property): Likewise.
3290 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3291 indications of Unixness.
3294 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3296 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3298 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3300 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3301 "unknown # object" error messages.
3303 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3304 (scm_i_index) and declare it static. Add a 'direction' argument
3305 to indicate what way the search should go.
3306 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3308 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3309 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3311 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3313 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3315 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3316 to avoid clash with various scsh forks.
3318 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3320 The following two changes (ramap.c, throw.c) are motivated by the
3321 apparent unportability of forward declarations of static arrays of
3322 the form `static foo bar[];'.
3324 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3325 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3327 * throw.c (scm_throw): Moved above scm_ithrow.
3329 * options.h: Removed the extern declarations of scm_yes_sym and
3330 scm_no_sym since these are static.
3332 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3334 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3336 * Makefile.am: remove AWK=@AWK@.
3337 Add a rule for generating errnos.list.
3338 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3340 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3341 don't extract errnos, just set a variable (avoids the
3342 need to recompile error.c just because configure is run.)
3344 * unif.h: update prototypes.
3345 * unif.c (scm_uniform_array_read,write): change the offset and
3346 length arguments to start and end, for consistency.
3348 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3350 * ioext.h: update prototypes.
3351 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3352 scm_read_line_x, it's a more general procedure using an
3353 interface from scsh. read-line and read-line! are now defined
3355 Note that the new read-line trims the terminator
3356 by default, previously it was appended to the returned string. An
3357 optional argument specifies how to process the terminator (scsh
3358 compatible). For the old behaviour: (read-line port 'concat).
3359 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3360 returns a pair, but is converted to multiple values if the scsh
3363 socket.h: update prototypes.
3364 * socket.c (scm_recvfrom): for consistency with other procedures,
3365 take start and end as separate optional arguments.
3366 (scm_recv, scm_recvfrom): don't allow the second argument
3367 to be a size, only a buffer. Change the scheme names to
3368 recv! and recvfrom!. Don't return the buffer.
3370 * ioext.h, posix.h: move prototypes too.
3371 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3372 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3373 "read.h" and "unif.h".
3374 * ioext.c: include "chars.h"
3376 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3378 * dynl.c: The dynamic linking and module registration functions
3379 are now defined even when dynamic linking is not available for the
3380 host system. Some of their functionality can be done without
3381 dynamic linking; when it's really needed, they throw errors.
3383 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3385 * configure.in: Only define DYNAMIC_LINKING when one of the system
3386 dependent functions is detected.
3387 * dynl.c (scm_dynamic_func): New function to get the address of a
3388 function in a dynamic object.
3389 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3390 produced by scm_dynamic_func as the thing to call.
3392 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3394 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3395 (scm_register_module_xxx, scm_registered_modules,
3396 scm_clear_registered_modules): New functions.
3398 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3400 * symbols.c (scm_sysintern): Renamed to
3401 scm_sysintern_no_module_lookup.
3402 (scm_sysintern): New function to take the place of the old
3403 scm_sysintern. It uses the current toplevel lookup closure to give
3404 the symbol its value. This is a temporary hack to put packages
3405 like gtcltk into their own module.
3406 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3407 us whether `scm_top_level_lookup_closure_var' has been initialized
3409 * eval.c (scm_init_eval): Set it.
3411 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3413 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3414 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3416 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3418 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3419 scm_sys_dup): deleted: FD capability will be added to other
3421 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3422 scm_fd_free, fd_smob, scm_intern_fd.
3423 (scm_open): renamed from scm_sys_open. Return a port instead of
3424 an FD object. Make the mode argument optional.
3425 (scm_sys_create): deleted, it's just a special case of open.
3426 (scm_init_filesys): move interning of constants O_CREAT etc.,
3427 here (were previously using SCM_CONST_LONG macro).
3428 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3430 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3431 include "fports.h" and <stdio.h>
3432 (scm_stat, scm_select): don't support FD objects.
3434 * error.h: adjust scm_syserror_msg prototype.
3435 * error.c (scm_syserror_msg): take an extra argument for errno.
3436 Using the global value didn't always work, since it could be
3437 reset by procedure calls in the message or args arguments.
3439 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3440 I don't understand why the check was there (and what about the
3443 * strop.c (scm_string_copy): allow shared substrings to be copied.
3445 * unif.h: corresponding change to prototypes.
3446 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3447 recognize two new optional arguments: offset and length. Allow
3448 the port argument to be an integer (file descriptor, for scsh).
3449 Include <unistd.h> for "read" prototype.
3451 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3453 * socket.c: don't include filesys.h.
3455 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3457 * Makefile.am: add AWK=@AWK@ (?)
3459 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3461 Add a rule to generate errnos.c from errnos.
3462 * error.c (scm_init_error): include errnos.c.
3463 * errnos_cnvt.awk: new file, converts the list of errno codes to
3465 * errnos_get.c: new file.
3466 * errnos.default: new file, contains errnos to try if they can't
3467 be extracted from errno.h.
3468 * configure.in: if using GCC, try and extract errno codes from
3472 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3474 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3475 * Makefile.am: Made libguile into a libtool library.
3476 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3477 Set libtool_libs to indicate that libguile is a libtool library.
3478 See guile/ChangeLog for details.
3479 * .cvsignore: ignore "*.lo", the libtool library objects.
3481 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3483 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3484 use htons in getservbyport argument.
3486 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3488 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3489 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3492 * objprop.c (scm_object_property): No need to take the CDR of the
3493 value returned by scm_object_properties, since Aug 20 change.
3495 * configure.in: When checking for struct linger, #include
3496 <sys/types.h> as well as <sys/socket.h>. I've never known
3497 <sys/types.h> to cause any portability problems, and Solaris's
3498 <sys/socket.h> needs it.
3499 * configure: Rebuilt.
3501 I think the Sun compiler has chosen a perverse way to interpret
3502 ANSI declarations combined with K&R definitions. We'll
3503 appease it a little bit. But when it invades France, we fight.
3504 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3505 * print.h (scm_iprlist): Here too.
3506 * numbers.c (scm_divbigdig): Change definition to match
3507 declaration in numbers.h.
3508 * unif.c (scm_makflo): Change definition to match declaration in
3511 * init.c (scm_boot_guile): Don't return the value of
3512 scm_boot_guile_1. This function doesn't return a value;
3513 scm_boot_guile_1 doesn't return a value (or return at all).
3515 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3518 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3519 compile. I have a feeling this function is a bad idea anyway ---
3520 one should always test for features, not systems.
3522 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3523 semicolons. Only pure luck kept this from being noticed earlier.
3525 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3527 * socket.c (scm_recvfrom): Added missing semicolon.
3529 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3531 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3532 the buffer and start and end positions for scsh networking
3535 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3537 * configure.in: Revert previous change to this file; the problem
3538 is due to transient automake weirdness.
3539 * configure: Rebuilt.
3541 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3542 PLUGIN/guile.libs. configure generates the latter from the former.
3543 * Makefile.in: Rebuilt.
3545 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3546 need this if we install scripts, like guile-snarf.
3547 * configure: Rebuilt.
3549 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3551 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3553 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3555 * socket.c (scm_addr_vector): fix faulty scm_listify.
3557 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3559 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3560 style block comment is no longer considered an error.
3562 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3564 * PLUGIN/guile.libs.in: New file.
3565 * PLUGIN/guile.libs: Removed from repository.
3566 * configure.in: Create PLUGIN/guile.libs from
3567 PLUGIN/guile.libs.in. This is for including additonal libraries
3568 needed for dynamic linking.
3569 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3570 instead of PLUGIN/guile.libs.
3572 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3574 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3576 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3577 occurrences of the given element from the list, not just the
3578 first. This is how the Emacs Lisp functions behave, how the
3579 analogous Common Lisp functions behave, and (I believe) how the
3580 older Maclisp functions worked. I realize that this change may
3581 break code, but it seemed better to break it before the Guile
3584 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3585 Their prototypes were already present in gc.h, but they weren't
3587 (scm_init_storage): Initialize scm_protects.
3588 * root.c (scm_protects): New element of scm_sys_protects.
3590 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3592 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3594 * libguile.h: Added #include "libguile/net_db.h".
3596 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3597 30 change. That file is only meant for communication between the
3598 configuration process and load.c. If code linked against libguile
3599 wants to get at the paths mentioned in libpath.h, it can call
3600 functions declared in load.h.
3602 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3604 * libguile.h: Removed #include "libguile/fdsocket.h"
3606 * net_db.c: Added #include <sys/socket.h>.
3608 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3610 * filesys.c (scm_input_waiting_p): use select in preference to
3611 FIONREAD, since the latter doesn't detect EOF.
3612 Throw error if neither select nor FIONREAD available.
3614 * socket.c (scm_connect): take a port, not a fd object.
3615 (scm_fill_sockaddr): throw an error if fam is not recognised.
3616 (scm_bind): use scm_fill_sockaddr.
3617 (scm_listen): take a port, not a fd object.
3618 (scm_accept): take and return a port. return #f in the car if
3619 address can't be got
3620 (scm_sock_fd_to_port): new procedure.
3621 (scm_socket): use scm_sock_fd_to_port.
3622 (scm_addr_vector): throw error if unrecognised address type.
3623 take an extra argument with the calling procedure name.
3624 (scm_getsockname): take a port. return #f if address can't be got.
3625 (scm_getpeername): take a port. return #f if address can't be got.
3626 (scm_recvfrom): take a port. return #f for address component if can't
3628 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3629 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3631 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3633 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3634 use separate data pointers, to allow them to be designed
3635 independently and reused.
3636 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3637 Renamed from catch_body, catch_handler, and uncaught_throw; made
3639 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3641 (scm_catch): Use the above.
3642 (scm_throw): Don't bother printing a message for an uncaught
3643 throw; we establish a default handler in init.
3644 * throw.h (scm_internal_catch): Prototype updated.
3645 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3647 (struct scm_body_thunk_data): New structure, used as data
3648 argument to scm_body_thunk.
3649 * init.c (struct main_func_closure): New structure, packaging up
3650 the data to pass to the user's main function.
3651 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3652 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3653 scm_internal_catch to establish a catch-all handler, using
3654 scm_handle_by_message. This replaces the special-case code in
3656 (invoke_main_func): Body function for scm_internal_catch; invoke
3657 the user's main function, using the main_func_closure pointer to
3658 decide what to pass it.
3659 * root.c (struct cwdr_body_data): Remove handler_proc member.
3660 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3661 (cwdr_handler): Removed.
3663 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3665 * socket.h (SCM_P): update bind prototype.
3666 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3667 include "feature.h".
3668 (scm_socket): return a port, not a file descriptor object.
3669 include "fports.h" and <unistd.h>
3670 (scm_bind): take a port, not a file descriptor object.
3671 take an extra argument for address args.
3673 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3674 INADDR_NONE, INADDR_LOOPBACK.
3676 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3678 * init.c: include net_db.h and not fdsocket.h.
3679 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3681 * Makefile.am: corresponding changes.
3682 * socket.h: renamed from fdsocket.h, fix names.
3683 * net_db.h: renamed from socket.h, fix names.
3684 * socket.c: renamed from fdsocket.c.
3685 remove _sys from procedure names.
3686 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3687 add "socket" to features list.
3688 * net_db.c: renamed from socket.c.
3689 remove _sys from procedure names.
3690 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3691 add "net-db" to features list.
3692 include "net_db.h". don't include <sys/socket.h> or
3695 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3697 * tags.h (scm_tags): Removed comma at end of last enumerator.
3699 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3701 Don't use GCC extensions to allocate space for debugging frames.
3702 (Here he goes again! Why do we put up with this?!)
3703 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3704 an scm_debug_info structure, not an in-line array of them. Add
3705 'info' member, to say how many vect elements we've used, for eval
3707 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3708 a new variable debug_info_end to mark the end of vect, instead of
3709 the address of the 'info' pointer itself.
3710 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3711 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3712 (SCM_APPLY): Explicitly allocate space for debug.vect.
3713 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3714 * stacks.c: Adjusted for new debug frame structure.
3715 (RELOC_INFO, RELOC_FRAME): New macros.
3716 (stack_depth, read_frames): Use them, and new scm_debug_frame
3717 element 'info', instead of magically knowing that eval frames have
3718 an info pointer sitting after vect.
3719 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3721 (scm_init_stacks): Formatting tweaks.
3723 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3725 Give GCC more control flow information, so it can be sure that
3726 variables aren't used uninitialized.
3727 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3728 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3729 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3730 scm_misc_error): Tell GCC that these functions never return.
3731 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3732 out the field type, call abort if SCM_ASSERT returns, to placate
3734 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3735 scm_wta ever returns. We can't handle this case anyway, and this
3736 gives the optimizer more information.
3737 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3738 scm_wta ever returns.
3740 In some cases, the code is fine, but GCC isn't smart enough to
3741 figure that out; this usually happens when one variable is only
3742 initialized and used when a particular condition holds true, and
3743 we know that condition will never change within a given invocation
3744 of the function. In this case, we simply initialize the variables
3745 to placate the compiler, hopefully to a value which will cause a
3746 crash if it is ever actually used.
3747 * print.c (scm_iprin1): Initialize mw_pos.
3748 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3749 * throw.c (scm_ithrow): Initialize dynpair.
3750 * unif.c (scm_uniform_vector_ref): Initialize cra.
3751 * struct.c (init_struct): Initialize prot.
3752 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3754 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3755 if EXPR contains no expressions.
3757 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3759 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3760 cause an infinite loop (???). So much for the algebraic
3761 equivalency of variable-sized arrays and alloca...
3763 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3765 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3766 a SCM boolean, not a C boolean.
3768 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3770 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3771 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3772 rules for raising scm_mtrigger. Previously, unfortunate but not
3773 unlikely circumstances could result in almost constant invokation
3774 of the gc. Now, this situations should be less likely, but they
3775 are not prevented completely.
3777 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3779 * numbers.c (scm_fuck): Procedure removed; looks like old test
3781 * numbers.h: Prototype removed.
3783 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3785 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3786 array to a pointer, to match my Nov 21 change in eval.c.
3788 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3790 * libguile.h: Added #include "libguile/backtrace.h", #include
3791 "libguile/stacks.h".
3793 * strings.c (scm_string scm_make_string scm_string_ref
3794 scm_string_set_x scm_string_equal_p scm_string_append):
3795 Bugfix according to scm patch from Aubrey Jaffer:
3796 Corrected long-standing
3797 (not (eqv? (integer->char 128)
3798 (string-ref (make-string 1 (integer->char 128)) 0)))
3799 bug found by John Kozak <jk@noontide.demon.co.uk>.
3801 * strports.c, strports.h: Make scm_eval_0str return the value of
3802 the last expression evaluated (previously, it returned void).
3804 * strports.c, strports.h: New function: scm_read_0str. Does what
3807 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3809 * simpos.c (scm_getenv): return #f if string can't be found in the
3810 environment instead of throwing an exception, for compatibility
3811 with numerous other systems.
3813 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3815 * Makefile.am (.c.x): Use guile-snarf.
3816 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
3818 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
3820 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3822 * backtrace.c (scm_display_error_message): Made non-static, and
3823 renamed from display_error_message.
3824 * backtrace.h (scm_display_error_message): Added extern decl.
3825 * throw.c (uncaught_throw): Use it to display the error message.
3827 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
3829 * inet_aton.c: Use #if 0, not #ifdef 0.
3831 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
3833 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
3834 to convert the returned value.
3835 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
3836 the offset argument.
3838 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3840 Add new interface to catch/throw, usable from C as well as
3842 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
3843 (scm_internal_catch): New function, replaces...
3844 (scm_catch_apply): Deleted.
3845 * throw.c (scm_catch_apply): Deleted; replaced with a more general
3846 mechanism which is a bit more code, but can be used nicely from C
3847 and implement the Scheme semantics as well.
3848 (scm_internal_catch): This is the replacement; it's named after
3849 the analogous function in Emacs.
3850 (scm_catch): Reimplemented in terms of the above.
3851 (struct catch_body_data, catch_body, catch_handler): New
3852 functions, used by scm_catch.
3853 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
3854 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
3855 support for new cwdr.
3857 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
3860 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
3862 * acconfig.h: Added DYNAMIC_LINKING symbol.
3863 * configure.in: Add option and checks for dynamic linking.
3864 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
3865 dynl.h: New files for dynamic linking support.
3866 * Makefile.am (libguile_a_SOURCES):
3868 (modinclude_HEADERS): Added "dynl.h".
3869 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
3871 * init.c (scm_boot_guile_1): Call
3872 scm_init_dynamic_linking to initialize dynamic linking support.
3874 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
3876 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
3877 (as we Schemers say). It needs to be global, so that I can tweak
3878 it for the proper operation of unexec.
3879 (scm_boot_guile_1_live): New variable, see above.
3881 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
3883 * guile-snarf.sh: Removed.
3884 * PLUGIN/guile.libs: Added dependency for -lm.
3885 * acinclude.m4: Renamed from aclocal.m4.
3886 * PLUGIN/greet: Removed.
3887 * Makefile.am, aclocal.m4: New files.
3888 * configure.in: Updated for Automake.
3890 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
3892 * eval.c (scm_definedp): Use top_level_lookup_closure_var
3893 and not top_level_lookup_thunk_var.
3895 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
3897 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
3899 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
3901 * eval.c (scm_definedp): Incompatibly changed to be a builtin
3902 Scheme function, instead of syntax. Single argument is now a
3905 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3907 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
3908 scm_ra_divide): Properly terminate statements passed as arguments
3909 to IVDEP macros. (Thanks to Bernard Urban.)
3911 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
3912 with non-constant sizes. (Thanks to Bernard Urban.)
3914 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3916 It's an "eval closure", not an "eval thunk." A thunk is a
3917 function of no arguments.
3918 * root.h (struct scm_root_state): Renamed
3919 top_level_lookup_closure_var from top_level_lookup_thunk_var.
3920 (scm_top_level_lookup_closure_var): Renamed from
3921 scm_top_level_lookup_thunk_var.
3922 * root.c (mark_root): Uses changed.
3923 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
3924 * init.c (scm_start_stack): Uses changed.
3925 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
3926 Change scheme-visible name to *top-level-lookup-closure* from
3927 *top-level-lookup-thunk*.
3929 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
3931 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
3932 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
3934 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
3936 * gc.c (struct scm_heap_seg_data): Doc fixes.
3938 * gc.c (scm_gc_sweep): Empty all segments' freelists before
3939 sweeping. Then, prepend each segment's free cells to its
3940 freelist, rather than wiping out the old value. (Thanks to Marius
3943 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
3944 scm_check_freelist, scm_debug_newcell): New functions and
3945 variables, for debugging freelist problems.
3946 * pairs.h (SCM_NEWCELL): New debugging version added.
3947 * gc.h (scm_debug_newcell): Added extern declaration, used by
3948 debugging version of SCM_NEWCELL.
3950 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3952 On some systems <libc.h> conflicts with <unistd.h>, and should not
3953 be #included at all.
3954 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
3955 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
3956 * configure.in: Call it.
3957 * posix.c, filesys.c: Use its results to decide whether or not to
3959 * configure, scmconfig.h.in: Rebuilt with autoconf and
3962 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
3964 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
3965 pointer to the stdio stream before calling scm_setbuf0, so the
3966 latter will be able to retrieve it. I'm surprised this didn't
3967 segfault earlier. (Thanks to Christopher Lee.)
3969 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3971 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
3974 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3976 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
3977 number of stack narrowing specifier pairs. The first specifier in
3978 a pair controls inner border, the second the outer border. A
3979 number means cut that number of frames, a procedure object means
3980 cut until that object is found in operator position in a frame.
3982 * root.c (cwdr): Bugfix.
3984 * read.c: Recording of positions disabled by default.
3986 * procs.c (scm_closure_p): New function.
3988 * posix.c (scm_tmpnam): New function.
3990 * load.c: Added #include "throw.h".
3991 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
3994 * load.c, load.h (scm_read_and_eval_x): New function.
3996 * eval.c: Renamed debug option "deval" to "debug".
3998 (scm_eval_x): `eval!' is no longer accessible from the scheme
3999 level. Motivation: We can't allow operations which introduce
4000 glocs into the scheme level. Guile's type system can't handle
4001 these as data. Use `eval' or `read-and-eval!' as replacement.
4003 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
4004 SCM_CONSP since this is a macro!; Set vframe.prev to
4005 scm_last_debug_frame instead of 0. In this way we can look
4006 "above" the virtual start stack frame if we wish.
4007 (scm_debug_hang): New function: Useful for debugging Guile in
4008 certain tricky situations. Will probably be removed later...
4010 * debug.h: Changed semantics of debug option "backtrace". This
4011 option now only indicates whether we want automatic backtrace at
4014 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4016 * ports.c: #include "filesys.h"
4017 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
4019 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
4020 Motivation: This is system specific code which is related to file
4021 I/O. It also may use select. Added code by Gary Houston to
4022 detect presence of character in stdio buffers.
4024 * libguile.h: #include "libguile/libpath.h"
4026 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4027 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4028 SCM_SITE_DIR; Install libpath.h among the other include files.
4030 * load.c, load.h (scm_sys_package_data_dir): New function.
4032 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4034 * stacks.h: Bugfix: Don't use tail-array length field as stack
4035 length field! This screwed GC.
4037 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4039 * _scm.h: Added #ifndef around definition of macros min and max.
4041 * __scm.h: Added hooks for threads to plugin to in ints protection
4042 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4043 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4044 the main code in these macros duplicated and spread over multiple
4045 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4046 SCM_THREAD_SWITCHING_CODE.
4048 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4050 * snarf.h: New file.
4051 * guile-snarf.sh: New file.
4052 * Makefile.in (inner_h_files): Added snarf.h
4053 (ancillary, install, uninstall, distclean): Added actions for
4055 (.c.x): Use guile-snarf.
4056 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4057 (gen_c_files): Note that these depend on guile-snarf.
4058 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4059 now in "snarf.h". Added #include "snarf.h" to get them.
4060 * libguile.h: Added #include "snarf.h".
4061 (Patches applied and tweaked by Jim Blandy.)
4063 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4065 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4066 standards suggest against providing prototypes for system
4067 functions. Thanks to Greg Troxel.
4069 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4071 * strports.c (scm_eval_0str): New function.
4072 #include "read.h", to get prototype for scm_read.
4073 * Makefile.in (strports.o): Update dependencies.
4074 * strports.h: New prototype.
4076 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4077 scheme name from "int?" to "integer?". It seems to do the job.
4078 * numbers.h: Rename prototype too.
4079 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4082 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4083 scm_num_eq_p): Rename these according to R4RS conventions: call
4084 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4085 to making libguile R4RS compliant without ice-9...
4087 * load.c (scm_sys_search_load_path): Search for files under all
4088 extensions listed in the %load-extensions variable. If FILENAME
4089 is absolute, return it unchanged, without searching the load path.
4090 (scm_loc_load_extensions): New variable, pointing to
4091 %load-extensions' value cell.
4092 (scm_init_load): Initialize it, and the value it points to.
4093 (scm_primitive_load_path): Improve error reporting.
4095 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4096 of new Scheme variable %load-hook.
4097 (scm_primitive_load): Apply %load-hook to filename.
4099 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4101 * configure.in: add tests for figuring out whether buffered data
4102 is available in a FILE structure, which is needed by char-ready.
4104 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4107 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4108 exceptions using misc_error instead of syserror. It seems a bit
4109 odd to throw an exception if a string can't be found in the
4110 environment, but it's consistent with open-file, stat etc.
4111 (simpos.h): remove sys_ from getenv.
4113 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4114 occurs, throw an error instead of returning errno. Return value
4116 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4118 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4120 * filesys.c (scm_stat2scm): derive file type and permissions from
4121 the stat mode and append them to the returned vector.
4122 There isn't much overhead in doing this and it avoids the need to
4123 work with S_IRUSR et al. in Scheme.
4124 Define symbols scm_sym_regular etc.
4125 (scm_init_filesys): don't intern S_IRUSR etc.
4127 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4128 and s_primitive_load_path.
4130 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4132 * error.h: don't declare error symbols. prototype for scm_misc_error.
4134 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4137 * error.c: use SCM_SYMBOL to set up error keys.
4138 scm_misc_error: new procedure.
4140 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4142 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4143 between `#!' and `!#' is ignored.
4144 (skip_scsh_block_comment): New function.
4146 * feature.c (scm_set_program_arguments): New argument, FIRST.
4147 * feature.h: Update prototype.
4148 * init.c (scm_boot_guile_1): Pass new argument to
4149 scm_set_program_arguments.
4151 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4153 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4154 (scm_boot_guile): Call scm_set_program_arguments here, later than
4155 the old initialization.
4157 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4158 initialization procedure.
4159 - Delete in, out, err arguments; there are other perfectly good
4160 ways to override these when desired.
4161 - Delete result argument; this function shouldn't ever return.
4162 - Rename init_func argument to main_func, for less confusion.
4163 - Delete boot_cmd argument; main_func is more general.
4164 -Add 'closure' argument, to help people pass data to main_func
4165 without resorting to global variables.
4166 - Abort if reentered; don't bother returning an error code.
4167 - Call scm_init_standard_ports to set up the default/current
4168 standard ports; no need to pass them to scm_start_stack.
4169 - Remove code to evaluate the boot_cmd, and start the repl; let
4170 the user do something like that in main_func if they want.
4171 - Remove code to package up a return value; main_func can do any
4173 - Call exit (0), instead of returning.
4174 (scm_start_stack): Don't initialize the I/O ports here; that's
4175 weird. Delete in, out, err arguments. Move guts to
4176 scm_init_standard_ports, scm_stdio_to_port.
4177 (scm_init_standard_ports): New function, to set up current and
4178 default standard ports.
4179 (scm_start_stack, scm_restart_stack): Make these static.
4180 * init.h (scm_boot_guile): Adjust declaration.
4181 (scm_start_stack, scm_restart_stack): Remove externally
4182 visible declarations for these.
4183 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4185 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4186 written out several times in scm_start_stack.
4187 * fports.h: New declaration for the above.
4189 * feature.c (scm_set_program_arguments): New function.
4190 * feature.h: New declaration for the above.
4192 * ports.c: Formatting tweak.
4194 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4196 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4197 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4198 for obtaining the address of a car or cdr field. Motivation:
4199 &SCM_CXR make assumptions about the internal structure of the
4202 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4203 Motivation: see SCM_CXRLOC.
4205 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4206 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4207 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4208 Motivation: Safer use. Some other macros are defined in terms of
4209 these operations. If these are defined using the SCM_SETCXR
4210 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4211 to inefficiency and an <e1> with side-effects could potentially
4212 break. Also, these particular operations are heavily utilized in
4213 the garbage collector. In unoptimized code there will be a
4216 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4217 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4218 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4219 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4220 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4221 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4222 vports.c: Cleaned up use of pairs: Don't make any special
4223 assumptions about the internal structure of selectors and
4224 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4225 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4226 (Among other things, this change makes it easier to build Guile
4227 with certain compilers which have problems with casted lvalues.)
4229 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4231 * stacks.c: Improve selection of relevant stack frames when making
4232 a stack object. Introduce one level of indirection in the stack
4233 object to make it possible to "narrow" to a certain region of the
4234 stack. This facilitates making use of more clever algorithms (not
4235 implemented) for selecting relevant frames and gives a cleaner
4236 design since selection of frames can be done independently of
4237 extraction of frames from the real stack.
4238 (scm_stack_id): Also take #t as argument which means look at
4241 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4242 Turn n_tail into an integer directly representing current number
4243 of frames in stack. Add field tail.
4245 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4247 * debug.c (scm_make_memoized): Made it available at scheme level.
4248 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4249 SCM_NIMP before applying heavier predicates in argument checking.
4250 (scm_local_eval): Also take memoized object as argument.
4252 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4253 aren't created with zero length, but should such a strange
4254 creature suddenly turn up...
4256 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4258 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4259 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4261 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4263 * variable.c (scm_make_variable): Make the name hint optional, as
4265 (anonymous_variable_sym): Renamed from variable_sym. All uses
4268 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4269 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4270 of scm_primitive_load_path was also changed to
4271 "primitive-load-path", from "%try-load-path". Callers changed.
4272 We'd like to respect the convention that a function named
4273 "try-mumble" should behave just like the function called "mumble",
4274 but return #f instead of signalling some error.
4275 * load.h: Rename prototypes.
4277 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4279 * print.c (make_print_state, grow_print_state), print.h: Modified
4280 the print state representation: Don't use a tail array for
4281 recording of circular references. Resizing of the print state
4282 structure invalidates the print state pointer. To avoid passing
4283 around an indirect print state reference to all printing
4284 functions, we instead let the print state reference a resizable
4287 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4289 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4290 Don't crash when passed an improper list terminated by a
4291 non-immediate value.
4293 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4295 Allocate data for structures on an eight-byte boundary, as
4296 required by the tagging system.
4297 * struct.c (alloc_struct): New function.
4298 (scm_make_struct, scm_make_vtable_vtable): Call it.
4299 * struct.h (scm_struct_n_extra_words): Bump to 3.
4300 (scm_struct_i_ptr): New "field".
4301 * gc.c (scm_gc_sweep): When we need to free the data, use the
4302 information stored by alloc_struct to find the beginning of the
4303 block allocated to the structure, so we can free it.
4305 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4307 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4310 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4311 (scm_debug_info): New member: id.
4313 * stacks.c: Stacks are now represented as structs; Stacks have an
4314 id given to them by `start-stack'.
4315 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4317 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4318 Changed stack representation.
4320 * debug.c (scm_procedure_name): Try procedure property `name' for
4321 compiled closures aswell.
4323 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4325 * eval.c: scm_i_name moved to gsubr.c
4326 (scm_m_define): Record names of all kinds of procedure
4327 objects. (Earlier, only closures were recorded.)
4329 * procprop.h: Added declaration of scm_i_name.
4331 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4332 (scm_make_gsubr): Record names of compiled closures.
4334 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4336 * debug.c, debug.h: Removed obsolete code.
4338 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4339 stacks.c: Renamed regs --> scm_contregs.
4341 * print.c (scm_free_print_state): Cleanup print state before
4342 returning it to pool. It is better to do it here than in
4343 scm_prin1 since scm_prin1 is called often.
4345 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4346 s_set_source_property_x): Check that first argument is a pair or a
4349 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4350 scm_i_line, scm_i_column and scm_i_breakpoint global.
4352 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4353 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4356 * debug.h: Added debug object smob declaration and macro
4359 * configure.in: Build with backtrace.o and stacks.o if debug
4362 * Makefile.in: Added entries for new files: backtrace.c,
4363 backtrace.h, stacks.c and stacks.h.
4365 * symbols.c (scm_sym2ovcell): Fixed documentation.
4367 * _scm.h (min, max): Added.
4369 * async.c: Moved `min' macro to _scm.h.
4371 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4372 SCM_BACKTRACE_INDENT.
4374 * eval.c: Added new debug options `maxdepth' and `indent'.
4376 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4378 * print.h: Added selector SCM_PRINT_STATE.
4380 * print.c: New functions: scm_make_print_state,
4381 scm_free_print_state.
4383 * print.h: Added declarations for scm_make_print_state,
4384 scm_free_print_state.
4386 * debug.c (scm_m_start_stack): New acro.
4388 * debug.h: Small cleanup.
4390 * init.c (scm_boot_guile_1): Moved scm_init_debug below

4418 More prototype-related changes from Marius Vollmer:
4419 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4420 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4421 * ports.h (ptobfuns): Added prototypes. This means some casting in
4423 * fports.c: Added casts for initializations, since the functions
4424 are defined to take FILE * as their stream argument, not SCM.
4425 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4426 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4427 to `char *str_data' to conform to prototype.
4429 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4431 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4433 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4435 * stime.c, stime.h: use SCM_P method.
4437 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4439 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4440 be given at least two arguments. Insist that lst's last element
4441 be a list, but don't make any requirements of its predecessors.
4443 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4445 * eval.c (scm_nconc2last): Revert last change; there seems to be
4446 other stuff going on here.
4448 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4450 * eval.c (scm_nconc2last): Make sure that each element of lst
4451 (which is a list of argument lists, except for the tail) is a
4452 proper list, i.e., finite and terminated by '().
4454 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4456 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4459 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4460 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4463 * vectors.c (scm_make_vector): Fill vectors with the undefined
4464 value, to help make Guile Scheme code more portable to other
4467 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4468 * symbols.h, tags.h: Doc fixes.
4470 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4472 * async.c (scm_take_signal): Doc fixes.
4474 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4476 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4477 want to subtract it from the modulus; we just want to leave it
4480 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4482 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4485 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4487 * throw.c (scm_catch_apply): Finished implementation of
4490 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4492 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4494 (scm_init_filesys): set "i/o-extensions" feature.
4497 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4499 * Makefile.in (root.o): Correct dependencies.
4501 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4503 * Makefile.in: Added dependency entry for root.o.
4505 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4506 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4508 * init.c (scm_start_stack): Set initial root continuation number
4511 * procs.c: New function: scm_thunk_p.
4513 * procs.h: Added declarations of scm_thunk_p.
4515 * root.c: Renamed `call-with-new-root' -->
4516 `call-with-dynamic-root'.
4517 (cwdr): Removed allocation of new root state. This should be done
4518 separately by use of scm_make_root.
4519 (scm_apply_with_dynamic_root): New function: Does what it
4520 sounds like. Needed when spawning threads.
4522 * root.h: Added member last_debug_frame to root state.
4523 Added #include "libguile/debug.h"
4525 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4526 arguments. The motivation is that code in root.c needs catch
4527 functionality, and we want to avoid code duplication.
4528 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4529 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4530 handlers that run without popping the stack into the dynwind
4533 * throw.h: Added prototypes for scm_catch_apply and
4536 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4538 * root.h (scm_root, scm_set_root): Decouple thread support details
4539 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4540 SCM_SET_THREAD_LOCAL_DATA.
4542 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4543 and tortoise scanning loop.
4545 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4547 * Makefile.in: Rebuild dependencies.
4549 * libguile.h: #include "libguile/print.h" before "smob.h", since
4550 the latter uses the print_state structure.
4552 * throw.c (scm_ithrow): Use the correct variable when checking to
4553 see if a given element of scm_dynwinds is a valid catch.
4555 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4556 structure, abort; don't just silently ignore the garbage.
4558 * _scm.h: #include "print.h" here, since it seems to be used just
4560 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4561 strports.c, unif.h: Don't #include "print.h".
4563 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4565 * feature.h (scm_loc_features): Removed external declaration.
4566 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4568 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4570 * feature.c (scm_init_feature): Added threads feature (needs to be
4571 initialized here, since features doesn't exist when
4572 scm_init_threads is called).
4574 * libguile.h: Added #include "libguile/../threads/threads.h".
4575 (This is a kludge to get thread support working. This should be
4578 * configure.in, acconfig.h: Added flags for thread support.
4580 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4583 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4584 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4587 * _scm.h: Added conditional #include "threads.h"
4589 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4590 SCM_THREADS_SWITCHING_CODE.
4592 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4593 allocate the basic dynamic root object.
4594 (scm_boot_guile): Added call to scm_init_root.
4596 * root.c, root.h: Added root smob.
4597 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4598 functions: Implements dynamic roots mostly according to spec in
4599 SCM manual. Main difference is that the second argument is a
4600 throw handler rather than an error "thunk".
4602 * root.h: Added declaration of scm_init_root.
4604 * root.c: Added #include "genio.h", #include "smob.h", #include
4605 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4607 (scm_init_root): Added #include "root.x".
4609 * throw.c: Added #include "stackchk.h"
4610 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4611 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4612 can be used in scm_call_with_new_root; Added reenabling of stack
4613 checking when catching a throw.
4615 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4617 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4619 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4620 element is not found, as per R4RS.
4622 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4624 * list.c: Doc fixes throughout.
4626 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4628 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4629 declare the char * to be const. Avoids a warning in rgx.c.
4631 * ports.h: spelling fix.
4633 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4636 * load.c (scm_sys_try_load_path): throw an error if file not found
4637 (like it says it in NEWS).
4639 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4641 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4642 PROPS slot to '(), not #f; it's an empty alist.
4644 * throw.h, throw.c: Use SCM_P instead of #if hair.
4646 Remove special support for uncaught throws; see throw.c for
4648 * throw.c (uncaught_throw): New function.
4649 (scm_ithrow): Call uncaught_throw if we don't find a throw
4650 target; don't mess with scm_bad_throw_vcell.
4651 (scm_bad_throw_vcell): Variable deleted.
4652 (scm_init_throw): Don't initialize it.
4654 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4657 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4659 * numbers.c (scm_istr2int): If the number is short (as most
4660 numbers are), just call scm_small_istr2int to deal with it.
4661 (scm_small_istr2int): New function, created by un-#ifdefing the
4662 non-bignum version of scm_istr2int and renaming it.
4664 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4666 * load.c (scm_sys_try_load): don't check whether value returned
4667 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4668 Change the Scheme name from %try-load to primitive-load.
4670 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4671 Can avoid passing a message, allowing it to be derived in the
4672 error handler (e.g., if we want to throw to the key both from
4675 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4677 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4678 references now have a new appearance which is more compact and
4679 also gives a clue about what the target of the reference is.
4680 By setting parameters in the print state, more fancy printing can
4681 be achieved. This is used by the (not yet commited) backtrace
4684 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4686 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4689 * print.c: Added #include "struct.h". Removed function
4692 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4693 scm_iprin1. Removed prototype for scm_prlist.
4695 * arbiters.c (prinarb),
4696 async.c (print_async),
4697 debug.c (prindebugobj, prinmemoized),
4698 eval.c (prinprom, prinmacro),
4699 filesys.c (scm_fd_print, scm_dir_print),
4701 mallocs.c (prinmalloc),
4702 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4703 smob.h (scm_smobfuns),
4704 srcprop.c (prinsrcprops),
4706 unif.c, unif.h (scm_raprin1, rapr1),
4707 variable.c (prin_var): Changed argument `int writing' to
4708 `scm_print_state *pstate'.
4710 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4711 that it will be called before scm_init_print.
4713 * print.c (scm_prin1): Print states are now allocated when calling
4714 scm_prin1 and then passed around to all printing functions as an
4715 argument. A cache `print_state_pool' enables reuse of print
4717 (scm_make_print_state): New function.
4718 (scm_iprin1): Adaption to print states.
4719 (scm_iprlist): An initial "hare and tortoise" scan brings down
4720 time complexity to O (depth * N). (Better time complexity will be
4721 achieved when the printing code is completely rewritten.)
4723 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4725 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4726 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4727 it gets done whether or not the cache variable has a value.
4729 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4731 Distinguish #f and ().
4732 * __scm.h: #undef SICP.
4733 * pairs.h (SCM_EOL): Delete this definition, equating it with
4735 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4736 the value it used to have. Doc fixes, too.
4738 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4740 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4741 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4742 Lord's implementation of structs, allowing for tail arrays as
4743 described in the manual. Also fixed some bugs. (Both the interface
4744 and the implementation should be improved.)
4746 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4748 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4749 People who whish to see the source can do `(print-enable 'source)'.
4750 Removed #ifdef DEBUG_EXTENSIONS.
4752 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4754 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4755 integer (assuming for now accepting an integer is a good thing).
4757 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4758 %S will be used instead for write'ing arguments.
4760 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4761 asserts. fix a few other asserts.
4762 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4763 scm_uniform_vector_ref, scm_array_set_x,
4764 scm_dimensions_to_unform_array): change args in
4765 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4766 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4767 scm_substring_fill_x): likewise.
4768 gsubr.c (scm_gsubr_apply): likewise.
4769 eval.c (SCM_APPLY): likewise.
4771 * eval.c (4 places): replace scm_everr with lgh_error or
4774 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4775 scm_memory_error): new procedures.
4776 scm_everr: deleted. can use scm_wta, dropping first two args.
4777 scm_error: convert NULL subr to SCM_BOOL_F.
4779 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4782 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4785 * error.c, error.h: new error keys: scm_arg_type_key,
4786 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4788 scm_wta: reimplement using lgh_error instead of scm_everr.
4790 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4792 * gdbint.c: scm_lread now has one more argument.
4794 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4795 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4796 loading source from non-file ports, which, e. g., happens when
4797 using the Emacs interface).
4799 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4802 * read.c: Added code for recording of positions of source code
4803 expressions; New functions: recsexpr, scm_lreadrecparen;
4804 _scm_make_srcprops --> scm_make_srcprops
4805 (scm_flush_ws): Removed updating of positions counters. This work
4806 is already done by scm_gen_getc
4808 * read.h: Added prototype for scm_lreadrecparen
4810 * print.c: Added #include "alist.h"
4812 * eval.c: Added #include "hash.h"
4814 * eq.c: Added #include "ramap.h"
4816 * options.c: Documentation fixes.
4818 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
4819 (scm_init_srcprop): Adjusted size of initial source-whash. Name
4820 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
4821 --> scm_make_srcprops
4823 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
4824 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
4825 function calls in the definition of the whash access macros.
4827 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
4829 * init.c (scm_boot_guile): Add level of indirection to
4830 scm_boot_guile_1() to ensure that stack base pointer is properly
4831 initialized. There was no guarantee that variable i was the
4832 highest/lowest variable on stack (i.e. the call frame of
4833 scm_boot_guile was not completely protected from gc).
4835 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
4837 * ports.h (scm_port_table): put back file_name, it will be used to
4838 support debugging. Undo related changes in fports.c, ioext.c,
4841 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4843 * ports.h (scm_port_table): remove file_name member for now, it seems
4845 * fports.c (scm_open_file): don't set file_name in PTAB.
4846 (prinfport): don't use file_name in PTAB.
4847 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
4848 * ports.c (scm_add_to_port_table): don't intialize file_name.
4849 (scm_port_file_name): remove for now.
4850 * gc.c (scm_gc_mark): don't mark PTAB file_name.
4852 * fports.h (scm_mkfile): prototype deleted.
4853 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
4855 * debug.c, unif.c: use scm_out_of_range instead of
4856 wta for range errors (ASSERT still needs work).
4858 * error.c, error.h (scm_out_of_range): new procedure.
4860 * error.c, error.h (scm_out_of_range_key): new key.
4862 * posix.c (scm_sync): #else was missing.
4864 * error.c, error.h: append _key to names scm_num_overflow and
4867 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
4868 of consing an empty list.
4869 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
4870 of macros, saves code and string space.
4871 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
4872 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
4873 lower case. Rename scm_syserror_m to scm_syserror_msg.
4874 error.h: prototypes for new procedures.
4876 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
4878 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
4880 * error.c, error.h: setup scm_num_overflow key.
4882 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
4883 Remove definition of SCM_OVSCM_FLOW.
4885 * fports.c (scm_open_file): use SCM_SYSERROR_M.
4887 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
4888 explicit message and args.
4890 * error.c, error.h, __scm.h: change system_error_sym to
4893 * error.c (system_error_sym): remove leading %% from the Scheme name
4896 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
4898 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4900 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
4901 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
4902 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
4903 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
4904 renamed. (These were introduced by unsupervised name
4907 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4909 * print.c: Added code for detection of circular references during
4910 printing. (init_ref_stack, grow_ref_stack): New functions. Added
4911 a hook for printing of closures (accessible via print options).
4912 This leads to a split of calls to scm_iprin1 into two classes:
4913 elementary print operations (e. g. the code which prints a smob)
4914 still use scm_iprin1 while top level calls (like scm_display) use
4915 scm_prin1. scm_prin1 begins by clearing the data structure used
4916 to record reference information.
4918 * print.h: Added declarations of scm_prin1 and scm_prlist.
4920 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
4922 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
4924 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
4926 * error.c (err_head): scm_iprin1 --> scm_prin1
4928 * debug.c: Adjusted header comment.
4932 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4934 * strerror.c: Doc fix.
4936 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4938 * gdbint.c (gdb_read): Now possible to run during GC.
4939 (unmark_port, remark_port): New functions.
4941 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
4943 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
4944 of allocating a new string object. Also, increase size by
4945 the factor 2 instead of 1.5.
4947 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
4949 * __scm.h (SCM_P): Corrected to run under traditional C.
4951 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
4954 * async.c: Calls to scm_sysintern corrected.
4956 * async.h (scm_async_clock): Redundant declaration removed.
4958 * continuations.c (scm_dynthrow): Redundant declaration removed.
4960 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
4961 Definition typos corrected.
4963 * debug.h: Missing declarations of functions in debug.c added
4966 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
4967 Missing declarations to functions in eval.c added.
4969 * filesys.c: Possibly uninitialized variable rv.
4971 * gc.h (scm_object_addr, scm_unhash_name): Missing
4972 declarations of functions defined in gc.c added.
4974 * genio.c: Possible typos str_data -> wstr_data. ???
4976 * genio.c: Possibly unintended shadowing of local variable
4977 `int c' (gotos out of scope of inner `c'). ???
4979 * init.c: Uninitialized `SCM last' may be used.
4981 * ioext.h: (scm_sys_isatty_p): Typo.
4983 * list.h (scm_list_head): Missing prototype for function in
4986 * numbers.c (scm_two_doubles): Changed from extern to static
4987 (is used only within numbers.c).
4989 * numbers.h: Repeated declarations removed.
4991 * ports.h (scm_close_all_ports_except): Declaration for the
4992 function defined in ports.c added.
4994 * posix.h: Missing declarations added.
4996 * procs.h (scm_make_subr_opt): Missing declaration added.
4998 * socket.h (scm_sys_gethost): Missing declaration added.
5000 * socket.h: Redundant declarations removed (they are in fdsocket.h).
5002 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
5003 Missing declarations added.
5005 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
5007 * struct.c: Uninitialized variable `SCM answer' may be used.
5009 * unif.c (l2ra): Declaration prototype.
5011 * unif.c (scm_array_equal_p): Dummy definition removed (it is
5012 defined in ramap.c).
5014 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
5015 Redundant declarations removed (they are in ramap.h).
5017 * variable.h (scm_make_udvariable,
5018 scm_make_undefined_variable): Declaration corrected to
5019 correspond variable.c.
5021 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
5022 Missing declarations added.
5024 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5026 * Makefile.in (distclean): Don't forget to delete fd.h.
5028 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5030 * fd.h.in, tags.h: Trivial cleanups.
5032 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5033 marksweep.h just declared functions from gc.c.
5034 * gc.h, libguile.h: Don't #include "marksweep.h".
5035 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5036 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5037 dependencies updated.
5039 * libguile.h: Don't #include "files.h"; it's been deleted.
5041 * files.c (scm_sys_delete_file): Moved to filesys.c.
5042 File is now empty; deleted.
5044 * filesys.c: scm_sys_delete_file is now here. Remove
5045 #if's; they seem to rely on remnants of an old portability
5046 regimen. If the problems come up again, solve them properly,
5047 using autoconf. Specifically: Don't test M_SYSV, and #define
5048 remove to be unlink if it's #defined; don't use remove just
5049 because HAVE_STDC_HEADERS is #defined.
5050 * filesys.h: Add declarations for scm_sys_delete_file.
5051 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5052 files.o, files.h, files.c, and files.x.
5053 * init.c: Don't #include "files.h", and don't call scm_init_files.
5055 Use SCM_P instead of PROTO; the latter intrudes on the user's
5057 * params.h: Deleted; definition of SCM_P moved to...
5058 * __scm.h: ... here, where it replaces PROTO macro.
5059 * libguile.h, smob.h: Don't #include "params.h".
5060 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5061 smob.h: Fix prototypes accordingly.
5062 * Makefile.in: Update dependencies.
5063 (inner_h_files): Remove params.h.
5065 * gc.c: #include "gc.h"; every module should include its header,
5066 to let the compiler cross-check the declarations against the
5069 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5070 simpos.h: #include "libguile/__scm.h".
5072 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5074 * init.c: Don't forget to #include smob.h and init.h.
5075 * Makefile.in: Dependencies updated.
5077 * smob.h: Use PROTO instead of #if __STDC__.
5079 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5081 * __scm.h: Doc fixes.
5083 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5084 <angles>; this allows `make depends' to work properly.
5086 * libguile.h: #include smob.h and pairs.h before the others; they
5087 define typedefs used by other headers.
5089 C files should #include only the header files they need, not
5090 libguile.h (which #includes all the header files); the pointless
5091 recompilation was wasting my time.
5092 * Makefile.in (all .o dependency lists): Regenerated.
5093 * libguile.h: Don't try to get a definition for size_t here...
5094 * __scm.h: Do it here.
5095 * _scm.h: Since this is the internal libguile header, put things
5096 here that all (or a majority) of the libguile files will want.
5097 Don't #include <libguile.h> here; that generates dependencies on
5098 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5099 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5100 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5197 * weaks.c: Get "weaks.h".
5199 * stackchk.h: #include "libguile/debug.h",
5201 * print.h, read.h: #include "options.h", since everyone who uses
5202 either of these files will need that.
5204 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5205 anyone who uses this file will need them to define the smob
5206 printing functions. Also, get markers.h, since people will need
5207 to #define the mark functions.
5209 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5210 * ports.h: ... to here.
5212 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5213 don't rely on archaic C default type rules.
5215 * fports.h: #include "libguile/ports.h", since you need that in
5216 order to parse this.
5218 * genio.h: #include "libguile/print.h", because you need that to
5219 parse this; don't bother #including "ports.h", since print.h gets
5222 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5224 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5225 this; it's now a reference to an element of *scm_root.
5227 * debug.h: Don't #include "options.h"; the compiler won't be able
5228 to find that once the headers are installed; instead, #include
5229 "libguile/options.h".
5230 * gc.h: Same, with marksweep.h.
5231 * mbstrings.h: Same, with symbols.h.
5232 * scmhob.h: Same, with _scm.h.
5233 * smob.h: Same, with params.h.
5235 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5236 C files; there's no need for this, and it forces recompilations
5239 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5241 * error.c (scm_error): declare scm_error_callback.
5243 * error.h: prototype for scm_error_callback.
5245 * __scm.h: define lgh_error.
5246 (SCM_SYSERROR): redefine using lgh_error.
5248 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5250 * error.c (scm_error): new procedure.
5252 * error.h: prototype for scm_error.
5254 * Makefile.in (install): install scmconfig.h from the current
5255 directory, not $(srcdir).
5257 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5259 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,

5267 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5268 vports.h, weaks.h: #include "libguile/__scm.h", not
5269 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5270 dependencies are within libguile properly.
5272 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5274 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5275 when scmconfig.h doesn't exist.
5277 * load.c (scm_sys_try_load): Correct spelling.
5279 * feature.c (scm_loc_features): Make this static.
5281 * Makefile.in (libpath.h): Omit trailing slash from path. We
5282 shouldn't require it of users, so why put it here?
5284 Move code to initialize and search %load-path from ice-9 to C
5285 code, so we can use the load-path to find the ice-9 boot code;
5286 this makes it easier to run Guile without installing it. See
5287 corresponding changes in guile/Makefile.in.
5288 * feature.c: Move stuff concerned with the load path to load.c.
5289 (scm_compiled_library_path): Deleted.
5290 Don't #include libpath.h here.
5291 * feature.h: Don't mention scm_compiled_library_path.
5292 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5293 <sys/stat.h>, and <unistd.h> (if present).
5294 (R_OK): #define if the system hasn't deigned to.
5295 (scm_loc_load_path): New variable.
5296 (scm_init_load_path, scm_sys_search_load_path,
5297 scm_sys_try_load_path): New functions.
5298 (scm_init_load): Initialize scm_loc_load_path to point to the
5299 value cell of the Scheme %load-path variable.
5300 * load.h: Add declarations for scm_sys_search_load_path,
5301 scm_sys_try_load_path.
5302 * init.c: Call scm_init_load_path.
5303 * Makefile.in (feature.o, load.o): Dependencies updated.
5305 * load.c, load.h: Rewrite using PROTO macro.
5307 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5309 * gc.c (scm_cellp): New function: C predicate to determine if an
5310 SCM value can be regarded as a pointer to a cell on the heap.
5312 * gc.h: Added declaration of scm_cellp.
5314 * gdb_interface.h: New file: The GDB interface header from the GDB
5317 * gdbint.c: New file: GDB interface.
5319 * gdbint.h: New file: GDB interface.
5321 * libguile.h: Added #include <libguile/gdbint.h>.
5323 * init.c (scm_boot_guile): Added scm_init_gdbint.
5325 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5326 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5327 found if object files and source are kept separate).
5329 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5331 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5333 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5335 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5336 TK_SRC_DIR; they're not relevant any more.
5338 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5339 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5341 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5343 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5344 search path, so we can find the <libguile/MUMBLE.h> headers.
5346 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5348 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5349 implicit in the .c.o rule.
5350 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5353 Put the library path in a header file, instead of passing it on
5354 the command line in every compilation.
5355 * Makefile.in (libpath.h): New target.
5356 (feature.o): Depend on libpath.h.
5357 (clean): Delete libpath.h.
5358 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5359 * feature.c: ... #include "libpath.h" here.
5360 * .cvsignore: Ignore libpath.h.
5362 Don't install the unwashed masses of Guile header files in the
5363 main #include path; put most of them in a subdirectory called
5364 'libguile'. This avoids naming conflicts between Guile header
5365 files and system header files (of which there were a few).
5366 * Makefile.in (pkgincludedir): Deleted.
5367 (innerincludedir): New variable; this and $(includedir) are enough.
5368 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5369 (installed_h_files): Divide this up. Now this variable lists
5370 those header files which should go into $(includedir) (i.e. appear
5371 directly in the #include path), and ...
5372 (inner_h_files): ... this new variable says which files appear in
5373 a subdirectory, and are referred to as <libguile/mumble.h>.
5374 (h_files): List them both.
5375 (install): Create innerincludedir, not pkgincludedir. Put
5376 the installed_h_files and inner_h_files in their proper places.
5377 (uninstall): Corresponding changes.
5378 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5379 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5380 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5381 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5382 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5383 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5384 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5385 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5386 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5387 vports.h, weaks.h: Find __scm.h in its new location.
5388 * __scm.h: Find scmconfig.h and tags.h in their new locations
5389 (they're both "inner" files).
5391 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5393 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5395 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5397 * posix.c: Doc fixes.
5399 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5401 * socket.c: Don't include a prototype for inet_aton; just use a
5402 K&R style declaration, to avoid warnings but minimize the chance
5403 of conflicts with the system.
5405 On NextStep, <utime.h> doesn't define struct utime, unless we
5406 #define _POSIX_SOURCE before #including it.
5407 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5408 * acconfig.h: New comment text for above CPP symbol.
5409 * configure.in: Call it.
5410 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5412 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5414 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5415 testing for __EMX__.
5417 * posix.c: #include <libc.h>, if it exists.
5419 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5420 don't even know if the latter exists.
5422 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5423 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5424 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5426 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5428 (scm_init_posix): Use them when initializing the Scheme constants
5431 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5433 * Makefile.in (libdir, includedir, bindir): Use the
5434 autoconf-supplied values, instead of deriving them ourselves.
5435 (pkgincludedir, datadir, pkgdatadir): New variables.
5436 (install, uninstall): Put the header files in a special
5437 subdirectory, not in the main search path.
5439 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5440 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5442 * Makefile.in (IMPLPATH): Deleted; never used.
5444 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5445 on the Tcl/Tk source any more.
5446 (INCLUDE_CFLAGS): Remove references to the above.
5448 * Makefile.in (version.o): Corrected dependencies.
5450 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5452 * libguile.h: #include "version.h"
5454 * init.c (scm_boot_guile): Call scm_init_version.
5455 * gscm.c (gscm_run_scm): Call scm_init_version.
5457 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5458 GUILE_VERSION): AC_DEFINE these.
5459 (acconfig.h): #undef the above symbols.
5461 * Makefile.in (libobjs): Add version.o.
5462 (installed_h_files): Add version.h.
5463 (c_files): Add version.c.
5464 (gen_c_files): Add version.x.
5465 (version.o): New rule.
5466 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5467 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
5468 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
5469 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
5470 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
5471 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
5472 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
5473 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
5474 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
5475 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5476 weaks.o): Add version.h to dependency lists.
5477 (markers.o): Remove duplicate rule.
5479 * version.h: New file.
5481 * version.c: New file.
5483 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5485 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5486 array; use it appropriately. Since GCC is quite happy to
5487 subscript functions, it never warned us about this; we should use
5488 -Wpointer-arith in the future. I guess we never tested
5491 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5493 * socket.c: Doc and copyright fixes.
5495 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5497 * debug.c: Fixed and improved gdb support.
5499 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5501 * socket.c: Added declaration of inet_aton to avoid compiler
5502 warning. (Hope this solution is correct.)
5504 * stime.c: Added declaration of ftime. (This is missing in
5507 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5509 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5511 * Makefile.in (c_files): add strerror.c.
5513 * strerror.c: new file from Emacs' sysdep.c.
5514 maybe configure should also check for sys_errlist.
5516 * configure.in (AC_REPLACE_FUNCS): add strerror.
5518 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5520 * debug.c (scm_init_debug): Added initialization for
5521 scm_evaluator_traps.
5523 * debug.h, debug.c: Various name changes.
5524 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5525 "debug-options-interface". See commentary in options.c.
5527 * options.h, options.c: Options now have documentation strings.
5528 Also added a long explanatory commentary.
5530 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5533 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5534 last_debug_info_frame is now updated in all cases.
5536 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5539 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5541 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5542 Added option STACK_CHECKING.
5544 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5546 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5548 * __scm.h: Removed symbols for debugging support.
5550 * acconfig.h: Added symbols for debugging support.
5552 * configure.in: Added user option for debugging support.
5553 --enable-debug will include the debugging code into libguile.a.
5555 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5556 scm_relocate_chunk_to_heap.
5558 * debug.c: New file: low-level debugging support. It also
5559 includes support for debugging with gdb. (The extensions to gdb
5560 are written by Per Bothner at Cygnus.)
5562 * debug.h: New file: low-level debugging support.
5564 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5565 argument pairs. Extensive modifications to the debugging
5566 evaluator. Added "SECTION:" commentaries to clarify what happens
5567 when, during double compilation. Renamed EVALIMP --> EVALIM.
5568 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5569 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5570 the beginning of the file. New procedure: scm_unmemocopy.
5571 Added some global state variables needed by the debugging
5572 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5573 check_entry, check_apply, check_exit, debug_options and
5574 evaluator_traps. New acro: undefine.
5576 * eval.h: Renamed EVAL --> XEVAL.
5578 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5579 --> scm_make_weak_key_hash_table.
5581 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5582 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5584 * libguile.h: Conditionally include debug.h
5586 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5587 scm_object_properties shouldn't return handle. `handle' now gets
5588 initialized in scm_set_object_properties_x. scm_object_properties
5589 doesn't any longer create an entry in scm_object_whash.
5591 * options.c: New file: handling of run time options.
5593 * options.h: New file: handling of run time options.
5595 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5597 * print.c: New procedure: scm_print_options
5599 * print.h: Defines for print options.
5601 * read.c: New procedure: scm_read_options
5603 * read.h: Defines for reader options.
5605 * root.h: Added scm_source_whash among scm_sys_protects.
5607 * srcprop.c: New file: source properties.
5609 * srcprop.h: New file: source properties.
5611 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5612 (Bug found by A. Green.)
5614 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5616 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5618 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5620 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5622 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5623 and should be called by the final client.
5625 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5627 * gc.h: Use the PROTO macro when declaring functions.
5628 * gc.c: Use the PROTO macro when declaring static functions.
5629 Remove the CPP hair around function definitions.
5631 * gc.c (scm_init_storage): Initialize scm_asyncs.
5633 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5634 preprocessor symbol; "__scm.h" is where it might get #defined.
5635 * __scm.h: Similar: #include <scmconfig.h> before testing
5638 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5640 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5642 * init.c (scm_boot_guile): Add init_func argument; call
5643 (*init_func) instead of calling scm_appinit; it's ucky to
5644 hard-code names for the user's procedures.
5645 * init.h (scm_boot_guile): Adjust declaration.
5647 * __scm.h (PROTO): New macro, for declaring functions with
5650 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5651 eliminate all the __STDC__ conditionals.
5652 (scm_boot_guile): Add declaration.
5653 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5654 Remove __STDC__ conditionals around function definitions; the
5655 declarations in init.h will provide the same information, more
5658 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5659 complain about it in the error message; the error message is
5660 adequate without that note, and there's nothing the user can do
5663 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5665 * Makefile.in (ancillary): Drop def.sed.
5667 * posix.c (scm_init_posix): Use numeric values, rather than
5668 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5669 F_OK. The symbols aren't available on some systems, and I'm
5670 pretty sure their values are fixed by common widespread practice.
5671 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5673 More functions unavailable on some systems.
5674 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5675 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5677 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5678 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5679 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5680 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5681 stub that signals an error as the #else.
5683 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
5685 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
5687 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
5689 * unif.c: include ramap.h.
5691 * read.c (endif): case_insensative_p renamed case_insensitive_p.
5693 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
5695 * ports.c: include sys/ioctl.h.
5697 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
5699 * configure.in: check for sys/ioctl.h.
5701 * ports.c: include <malloc.h> not "malloc.h".
5703 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5705 * fports.c: remove ttyname and tmpnam declarations.
5707 * posix.c: fewer ttyname declarations.
5709 * fports.c: include <string.h> not "string.h".
5711 * init.c, ioext.c: include string.h and unistd.h.
5713 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5715 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
5716 genio.c, simpos.c, vports.c: include string.h.
5718 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
5720 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
5722 (scm_addr_buffer_size): change type from scm_sizet to int.
5723 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
5724 from scm_sizet to int.
5726 * error.c: include unistd.h.
5728 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
5731 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
5733 * __scm.hd, def.sed: deleted.
5735 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
5737 Changes for NeXT, suggested by Robert Brown.
5738 * configure.in: Call AC_TYPE_MODE_T.
5739 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
5740 NeXT. Put header file list in alphabetical order.
5741 * configure, scmconfig.h.in: Regenerated.
5742 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
5744 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
5747 * acconfig.h: New file, providing documentation for the CPP
5748 symbols defined in configure.in
5749 * acconfig-1.5.h: Removed; superceded by the above.
5751 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
5753 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
5755 * fports.c (scm_open_file): don't return #f, throw error.
5757 * ioext.c (fileno): renamed from %fileno.
5758 (soft-fileno): deleted.
5760 * ports.c (scm_port_revealed): don't need to check for -1 from
5762 (scm_set_port_revealed_x): return unspecified, not #f.
5764 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
5766 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
5768 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
5770 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.

5774 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5775 This is necessary on Ultrix, and doesn't hurt portability.

5778 (installed_h_files): Put in alphabetical order.
5779 Remove duplicate entries for markers.h and unif.h.
5780 (c_files): Remove duplicate entries for markers.c.
5781 (ancillary): Renamed from anillery; all uses changed. Remove
5782 PLUGIN; it's a directory, and needs special treatment in dist-dir.
5783 Remove all the ../doc/* files; doc/Makefile.in handles that.
5785 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5787 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5788 every if must have an else, or else the whole command has a
5789 non-zero exit code whenever the if's condition is false.

5856 matter so long as it is non-0 (got rid of "* 4").
5858 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
5860 * gscm.h: gscm_mkarray eliminated (presumably was not being used
5861 since its definition was bogus).
5863 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
5865 * mallocs.[ch]: back again (for rx at least).
5867 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
5869 * ports.c: removed functions relating to the mapping between ports
5870 and descriptors. (That stuff is unix-specific and should be collected

5878 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
5879 handled correctly (SCM_FREEP was applied to them) -- test for

6048 initialization to fix a race condition.
6050 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

6077 The weird symbol syntax is also a bit bogus (emacs doesn't quite
