1 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
3 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
4 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
7 Do magic to mix reads and writes on stdio FILE-based ports.
8 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
10 (pre_read, pre_write): New functions.
11 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
12 local_fputs): Call them.
13 (local_fflush): Mark the port as ready for reading and writing.
14 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
15 flags on new port objects. This might not be accurate --- who
16 knows what state the FILE * is in when we get it --- but it won't
17 do extraneous calls to fflush or fseek, so it's no worse than the
18 behavior before this change.
19 * ports.h: Add comment.
21 Centralize the creation of port objects based on stdio FILE * in
22 fports.c; don't just throw them together anywhere.
23 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
24 what the rest of Guile wants. Don't set the revealed count;
25 that's only appropriate for stdin, stdout, stderr.
26 (scm_standard_stream_to_port): This function does set the revealed
28 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
29 not scm_stdio_to_port.
30 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
31 * fports.c (scm_open_file): Same.
32 * posix.c (scm_pipe): Same.
33 * socket.c (scm_sock_fd_to_port): Same.
34 * ioext.c (scm_fdopen): Same.
35 (scm_freopen): Moved from here to...
36 * fports.c (scm_freopen): ... here. This is really something that
37 munges the internals of an fport, so it should go here.
38 * fports.h (scm_stdio_to_port): Adjust prototype.
39 (scm_standard_stream_to_port, scm_freopen): New protoypes.
40 * ioext.h (scm_freopen): Prototype removed.
42 * filesys.c (set_element, get_element): This can work on both pipe
43 and file ports, so use SCM_FPORTP to typecheck, instead of testing
46 * scmconfig.h.in: Regenerated.
48 Change the definition of the functions in scm_ptobfuns so that
49 they get passed the port object, not the port's stream.
50 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
51 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
52 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
53 Pass the port itself to the scm_ptobs function.
54 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
55 scm_generic_fgets): Same.
56 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
57 getc_void_port, fgets_void_port, close_void_port): Just change the
58 argument names; these functions don't really do anything.
59 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
60 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
61 port as an argument, and use SCM_STREAM to get the stdio FILE *.
62 Also, use prototyped definitions, and get rid of the extra
64 (scm_fptob, scm_pipob): We don't need casts here any more.
65 * strports.c (prinstpt): Use prototype declarations.
66 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
67 and use SCM_STREAM to get the string info. Also, use prototyped
68 definitions, and get rid of the extra declarations.
69 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
72 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
73 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
75 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
76 scm_fgets, for consistency.
77 (scm_fptop, scm_pipob): References updated.
79 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
81 Include the source location in error messages for scripts.
82 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
83 stack is still there when we catch the error.
84 * throw.c (handler_message): If we are handling an error with a
85 message, then put together the proper arguments and call
86 scm_display_error, instead of scm_display_error_message. That
87 displays source location, if it can find it.
89 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
91 * gc.c (scm_unprotect_object): Change this so that calls to
92 scm_protect_object and scm_unprotect_object nest properly.
93 (scm_protect_object): Doc fixes.
95 * strings.c (scm_string_set_x): Require the argument to be a
96 writable string, not a substring or a symbol.
97 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
98 (Thanks to John Redford and Charbel Jacquin.)
100 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
102 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
104 * eval.c (safe_setjmp): Remove this misunderstanding.
105 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
108 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
110 * libguile.h: Mark these as C declarations, for compilation by C++
113 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
114 __cplusplus clause. I seriously doubt this ever worked the way
115 the author seems to have intended.
117 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
119 Utterly needless cleanups to hopelessly messy code.
120 * ports.c: Doc fixes.
121 (scm_fflush): Moved to ...
122 * genio.c (scm_fflush): ... here, amongst all the other port
123 method invocation functions.
124 * genio.h, ports.h: The prototype moves too.
126 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
128 * backtrace.c (display_error_body): The current frame does not
129 always have a parent frame; consider a function called directly
130 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
133 * alloca.c (alloca): Undo yesterday's changes, and simply call
134 malloc directly for storage, and abort if we don't get what we
135 want. The situation is much simpler --- just call malloc. Emacs
136 has bizarre/evil requirements (signal handlers might malloc unless
137 you set this global flag, so you have to set the flag around all
138 calls to malloc) which we are certainly not going to conform to,
139 so we can do the simple and obvious thing.
141 * coop.c (coop_condition_variable_wait): Make this function
142 static. It's only useful internally --- you should never just
143 wait on a condition variable.
144 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
146 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
148 * unif.c (scm_array_set_x): Accept any kind of number as an
149 element for a uniform vector of doubles. This is more consistent
150 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
152 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
153 works; I can't conveniently test it myself. (Thanks to Dvid
154 Tillman for the bug report.)
158 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
159 from here, not from scm_compile_shell_switches (which is a pretty
160 dumb place to do it).
161 (scm_load_startup_files): New function.
162 (scm_ice_9_already_loaded): Variable moved to here from script.c.
163 * script.c (scm_compile_shell_switches): Don't load the startup
165 (scm_ice_9_already_loaded): Variable moved.
166 * init.c (scm_load_startup_files): Prototype for new function.
167 * gh_init.c (gh_enter): Doc fix.
169 1998-10-03 <jimb@savonarola.red-bean.com>
171 Some anti-warning changes from Greg Harvey.
172 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
173 warnings when it doesn't understand our NORETURN declarations in
175 * posix.c (scm_mknod): Similar.
177 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
179 * posix.c (scm_getpwuid): If we can't find an entry, return our
180 own message, instead of using scm_syserror --- the getpwMUMBLE
181 functions don't set `errno' to anything interesting.
183 1998-10-03 <jimb@savonarola.red-bean.com>
185 Get rid of warnings from the cooperative threading system.
186 * threads.h (scm_single_thread_p, scm_yield,
187 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
188 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
189 scm_wait_condition_variable, scm_signal_condition_variable): Add
190 prototypes for these Scheme-visible functions.
191 * coop-defs.h (coop_next_runnable_thread,
192 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
193 Prototypes for these here, even though they're from iselect.c.
194 (coop_condition_variable_wait, coop_join): Add prototypes.
195 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
196 scm_threads_free_condvar): Make these smob functions static.
197 * coop-threads.h (coop_init): Give this a real prototype.
198 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
199 (coop_next_runnable_thread): No need to provide prototype; it's in
202 * scmconfig.h.in: .detarenegeR
204 * iselect.c, threads.c: Doc fixes.
206 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
208 * Makefile.in: Regenerated with a patched automake, to get
209 dependency generation right when using EGCS.
211 * inet_aton.c (inet_aton): Add prototype, to remove compiler
212 warning. (Thanks to Robert Pluim.)
214 * inet_aton.c (inet_aton): Reassure the compiler that the
215 arguments to the <ctype.h> macros are all unsigned characters, not
218 1998-10-03 <jimb@savonarola.red-bean.com>
220 Getting rid of more warnings...
221 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
222 today's change to ../configure.in.
223 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
224 * scmconfig.h.in: Regenertaded.de.,.__
225 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
226 (scm_localtime, scm_mktime): Use a const char * to manipulate the
229 * readline.c: Doc fix.
230 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
231 * readline.h (scm_filename_completion_function): Add prototype.
232 (scm_init_readline): Make this into a prototype.
234 * readline.c (scm_filename_completion_function): Use SCM_PROC to
235 declare this, instead of calling scm_make_subr manually.
237 1998-10-02 <jimb@savonarola.red-bean.com>
239 * readline.h (scm_init_readline): Add prototype for this.
240 (scm_init_readline): Make this a real prototype.
242 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
244 Warning fixes from Maciej Stachowiak:
245 * backtrace.h (scm_display_application, scm_backtrace): Add
247 * debug.c (scm_m_start_stack): Make this function static.
248 * fluids.h (scm_fluid_p): Add prototype.
249 * procprop.c (scm_i_procedure_arity): Make this function static.
250 * regex-posix.c (scm_regexp_error_msg): Make this function static.
251 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
252 * root.h (scm_dynamic_root): Add external prototype.
253 * scmsigs.h (scm_usleep): Add external prototype.
254 * script.h (scm_init_script): Use prototype, not K&R decl.
255 * stacks.h (scm_stack_id): Add external prototype.
256 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
258 1998-09-30 Mark Galassi <rosalia@cygnus.com>
260 * gh.h: took out the definitions of vset and vref, since they are
261 replaced by the proper vector routines that correspond to the R4RS
264 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
266 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
267 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
268 third argument, a C expression that should result in a SCM value,
269 which is used to initialize the variable. Reimplemented
270 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
273 * version.h (scm_libguile_config_stamp): Add prototype.
274 (From Maciej Stachowiak.)
276 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
278 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
279 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
281 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
283 * print.c (scm_iprin1): Rather than having one i, and using it in
284 several places, declare a fresh i local to each block where it is
285 used, and give it a signedness appropriate to its use in each case.
288 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
291 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
292 signed/unsigned clashes.
294 * posix.h (scm_tmpnam): Added prototype.
296 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
297 scm_make_subclass_object): Add external prototypes.
299 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
300 comparison is okay here.
302 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
304 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
305 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
307 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
310 * load.c (swap_port): Make this function static.
312 * load.c (scm_search_path): Make max_path_len and max_ext_len
313 unsigned, since they're compared against string sizes.
315 * load.c (init_build_info): Make i unsigned.
317 * ioext.h (scm_read_line): Add prototype.
319 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
320 scm_hash_fn_remove_x): Make hash bucket index local variable k
321 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
322 accurately as possible.
324 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
325 comparisons, and range checking to make sure those casts are
328 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
329 signed/unsigned comparisons.
331 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
332 avoid signed/unsigned comparisons.
333 * smob.h (scm_numsmob): Change extern declaration to match.
335 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
336 avoid signed/unsigned comparisons.
337 * ports.h (scm_numptob): Change extern declaration to match.
338 (scm_current_load_port, scm_set_port_line_x,
339 scm_set_port_column_x): New prototypes.
341 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
342 test code, and it causes warnings.
344 * gh.h (gh_int2scmb, gh_uniform_vector_length,
345 gh_uniform_vector_ref): Added prototypes.
347 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
348 debugging support unconditionally. That's backtrace.c, stack.c,
349 debug.c, and srcprop.c.
350 (EXTRA_libguile_la_SOURCES): Omit those from here.
351 * Makefile.in: Regenerated.
353 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
355 * options.c (scm_options): Bugfix: Allow empty list of options!
357 * debug.c, debug.h (scm_single_step): Removed.
358 (scm_with_traps): New procedure. This procedure could easily be
359 written in Scheme but needs to be highly optimized.
361 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
363 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
364 Check SCM_TRAPS_P before trapping.
366 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
368 Changes to avoid signed/unsigned comparison warnings.
369 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
370 (scm_gc_sweep): Make n and j local to the blocks they're used in,
371 so they can have appropriate types for each application. Make i
372 signed. Use initializers in some spots. I'll probably pay for
374 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
375 (scm_must_realloc): Make nm unsigned.
376 (init_heap_seg): Make new_seg_index and n_new_objects signed.
377 (scm_init_storage): Use prototype-style definition, and make the
379 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
380 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
382 * filesys.c (scm_readlink): Make local vars rv and size ints, to
383 avoid signed/unsigned comparison warnings, and because the return
384 value of readlink may be -1. Don't bother casting the third
385 argument to readlink.
387 * filesys.c (scm_dirname, scm_basename): Move these to their own
388 page, at the end of the file.
389 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
391 * eval.h (scm_eval_options_interface): Add external prototype for this.
392 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
394 * eval.c (scm_lookupcar1): Make this static.
396 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
397 Make these prototype declarations, not K&R-style.
399 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
400 unsigned comparison warning.
402 * appinit.c: File removed. It had a single function in it, empty,
403 whose reason for existence is explained in no documentation or
404 comment. I think it's there as a default for some Tcl-style
405 initialization, but Tcl abandoned that approach a while ago.
406 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
407 (BUILT_SOURCES): Remove appinit.x.
408 * Makefile.in: Regenerated.
410 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
412 * Makefile.in: Regenerated using the last public version of
413 automake, not the hacked Cygnus version.
415 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
417 Remove Totoro kludge.
418 * Makefile.in, scmconfig.h.in: Regenerated.
419 * init.c, readline.c: Don't check if TOTORO is #defined.
421 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
423 * Makefile.am: Adjust for new thread configuration system.
424 (INCLUDES): Include the value of THREAD_CPPFLAGS.
425 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
427 (THREAD_LIBS): Definition deleted; automake will generate such
428 things automatically.
429 * Makefile.in: Regenerated.
431 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
433 Simplify smob and port marking; set the mark bit in the generic
434 marking code, and make marker routines only responsible for
435 turning up outgoing pointers.
436 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
437 before calling the marking function. Don't call the marking
438 function if it's zero.
439 * markers.c (scm_mark0): Just return #f. This function isn't
440 necessary at all now, but it's harmless to call it. We'll leave
441 it in so other folks' code doesn't croak at link time.
442 (scm_markcdr): Don't call SCM_SETGC8MARK.
443 * async.c (mark_async): Don't call SCM_SETGC8MARK.
444 * dynl.c (mark_dynl_obj): Same.
445 * root.c (mark_root): Same.
446 * srcprop.c (marksrcprops): Same.
447 * unif.c (markra): Same.
448 * variable.c (scm_markvar): Same.
449 * ports.c (scm_markstream): Same.
450 (void_port_ptob): Specify zero for our marking function.
451 * debug.c (debugobjsmob): Same.
452 * dynwind.c (guardsmob): Same.
453 * filesys.c (dir_smob): Same.
454 * fluids.c (fluid_smob): Same.
455 * fports.c (scm_fptob, scm_pipob): Same.
456 * mallocs.c (mallocsmob): Same.
457 * regex-posix.c (regex_t_smob): Same.
458 * smob.c (freecell, flob, bigob): Same.
459 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
460 * throw.c (jbsmob, lazy_catch_funs): Same.
462 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
464 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
465 scm_copy_tree on code in order not to let memoized code to leak
466 out. Thus, scm_copy_tree needs to copy vectors as well since
467 quasiquote can introduce evaluated code also inside vector
470 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
472 * eval.c (scm_copy_tree): Removed ability to copy vectors.
474 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
475 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
478 * unif.c: Say that ivect and uvect are of type signed and unsigned
479 long instead of int in commentary so that it correctly describes
482 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
484 * stime.c: Removed declaration of strptime. (It should be
485 declared by the system headers. If it turns out that some systems
486 don't, we'll handle that then.) (Thanks to Greg Troxel.)
488 * stime.h: Renamed TIMEH --> STIMEH
490 * backtrace.c (scm_display_error, scm_display_backtrace): In order
491 to increase portability, don't use structure assignment.
492 (Thanks to Nicolas Neuss.)
494 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
496 (finalize_fd_sets): Added empty statement after last case label.
497 (Thanks to Nicolas Neuss.)
499 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
502 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
504 * init.c, readline.c: OK, I won't have these readline.x bug
505 reports anymore. We've had them since April. The current reason
506 is a completely unintelligible failure of totoro.red-bean.com to
507 do the test for rl_getc_function in libreadline correctly. This
508 kludge overrides the test if we're on totoro so that the snapshot
509 generation process can work.
511 * readline.c: Define a strdup replacement if not existent on system.
513 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
515 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
516 This change makes scm_make_vector R5RS compatible. We cannot keep
517 the third argument since people want to be able to deduce the form
518 of the C function call only by looking at R5RS. (At the same time
519 we have removed some unnecessary complexity!)
521 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
522 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
523 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
524 argument in call to scm_make_vector.
526 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
528 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
529 This macro is useful in applications.
531 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
533 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
534 (scm_parse_path, scm_search_path): New Scheme level procedures.
536 * load.h (scm_internal_parse_path, scm_parse_path,
537 scm_search_path): Declared.
539 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
541 * filesys.c (dirname, basename): New procedures.
543 * init.c (scm_boot_guile_1): Removed condition around
546 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
547 new data type (guards) for representation of C level guards and
548 data on the wind chain.
549 (scm_internal_dynamic_wind): New function.
551 * dynwind.h: Declare scm_internal_dynamic_wind.
553 * root.h (scm_root_state): Added scm_cur_loadp.
555 * root.c (mark_root): Added comment about cur_loadp.
557 * load.c: #include "dynwind.h";
558 (scm_primitive_load): Use scm_inner_dynamic_wind to update
561 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
563 * ports.c (current-load-port): New procedure.
565 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
567 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
568 not a tty, return #f.
570 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
571 to Julian Satchell and Roland Kaufmann.)
573 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
574 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
576 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
578 * debug.h, debug.c (scm_start_stack): New function. Implements
579 the guts of old scm_m_start_stack.
581 * debug.c (scm_m_start_stack): Use scm_start_stack.
583 * init.c (scm_start_stack, scm_restart_stack): Renamed to
584 start_stack and restart_stack. (These have static scope.)
586 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
588 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
589 readline functions to come in release 2.3. (Thanks to Chet
591 (handle_errors): Use the above functions.
593 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
595 * readline.c: Improvements for readline support: Handle errors
596 better; Implement before-read-hook.
598 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
600 * init.c (scm_boot_guile_1), readline.c: Test for
601 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
602 assure that we have version >= 2.1.)
604 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
606 * readline.c (scm_readline): Defer interrupts while we're calling
609 * readline.c (scm_add_history): Bugfix: Do strdup before giving
610 away the string to add_history.
611 (completion_function): Do completion for readline. (Thanks to
613 (scm_filename_completion_function): New procedure: Filename
615 (current_input_getc): New function. Use this one instead of
616 standard getc from readline.
618 * throw.c, throw.h (scm_handle_by_throw): New function: This
619 handler throws errors to next handler on the dynwind chain.
621 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
623 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
626 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
628 * procprop.c (scm_i_procedure_arity): New function. Returns arity
630 (scm_procedure_properties): Modified to return arity together with
632 (scm_procedure_property): Added the read-only property `arity'.
633 (scm_set_procedure_property_x): It is an error to set the `arity'
636 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
637 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
639 * procprop.h (scm_sym_arity): New symbol.
641 * objects.c (scm_set_object_procedure_x): New procedure: Use this
642 to set the dispatch procedure of an operator or entity object.
644 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
645 Made procedure slots read-only.
647 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
648 scm_tcs_cons_gloc case in zero args switch; Fixed args
649 construction for operators in scm_tcs_cons_gloc case in two args
652 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
654 * fluids.c: Removed use of assert.h (in order to avoid
657 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
659 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
661 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
662 change makes the evaluator safer at the cost of evaluation speed.
663 It handles the case when the user has added a non-immediate
664 improper end of the application form, e.g., `(+ 0 . x)'.
665 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
666 minimize the extra cost as much as possible. The new code is
667 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
668 problem with structs planted directly in the code (e.g. by a
669 macro). This no longer causes segmentation fault. (Thanks to
672 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
673 arg `proc' in order to be able to throw errors; New argument
676 * Removed extra #include "debug.h"
678 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
680 * scmsigs.c: Declare usleep as returning void on some systems.
681 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
684 * coop.c (usleep): Return void on some systems.
686 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
688 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
690 * coop.c: Changed return type of usleep to int.
692 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
693 isn't found in the OS.
695 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
696 isn't enabled. (Thought that I had made this change ages ago...)
698 * iselect.c: Declare bzero if not defined by OS.
700 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
702 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
703 condition. (Thanks to John Tobey.)
705 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
706 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
709 * __scm.h: Start the long-term project of moving to POSIX threads.
710 Phase 1: Classification of all critical sections.
711 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
712 for A sections. (See comments in __scm.h for details.)
714 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
715 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
717 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
719 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
720 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
721 (libpath.h, versiondat.h): Replaced dependency on Makefile with
722 dependencies on $(srcdir)/Makefile.in
723 $(top_builddir)/config.status in order to avoid circularity.
725 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
726 from argc if argc was 0 initially.
728 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
729 in generation of libpath.h.
731 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
733 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
734 libguile from 2 to 3.
736 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
738 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
740 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
742 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
743 scm_set_port_column_x, scm_port_filename,
744 scm_set_port_filename_x): Removed optional arguments. Added
745 proper argument checking.
747 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
748 stack size in machine words.
750 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
751 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
752 to Ole Myren Röhne.)
754 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
756 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
757 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
759 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
762 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
763 procedure apply: Copy argument lists before pushing them unto the
764 environment so that the environment won't get mutated due to
765 manipulation of procedure arguments. This should perhaps be
766 regarded as a temporary solution until someone finds a more
767 efficient one. (Thanks to Maciej Stachowiak.)
769 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
771 * script.c (scm_compile_shell_switches): Use "guile" as default
772 zero arg if argc is NULL.
774 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
776 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
777 is zero. (Thanks to Dirk Herrmann.)
779 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
781 * ports.c (scm_add_to_port_table): First line is now line 0
782 (was 1). (Interface changed according to suggestion by Per
785 * backtrace.c (display_header): Add 1 to line and column numbers
786 when presenting them to the user.
788 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
789 from debug.c --> eval.c
791 * eval.h, eval.c (scm_eval_options_interface): New options
793 (SCM_EVAL_STACK): New option: Size of newly created stacks,
794 i.e. stacks for new threads.
796 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
798 * eval.c (unsafe_setjmp): Removed with #if 0.
800 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
803 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
804 to avoid compiler warnings.
806 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
808 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
810 * throw.c (handler_message): Print message on current error port
811 instead of default error port. (Thanks to Maciej Stachowiak.)
813 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
815 * ports.c (scm_add_to_port_table): allocate in units of
816 struct scm_port_table *, not struct scm_port_table.
817 * posix.c (scm_close_pipe): remove the port from the port table
819 Thanks to Rob Engle for both fixes.
821 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
823 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
824 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
826 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
828 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
830 * backtrace.c (display_error_body, display_backtrace_body),
831 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
832 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
833 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
834 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
837 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
838 don't receive the jmpbuf arg anylonger.
839 (scm_catch): Don't accept a #f tag.
840 (scm_throw): Check that key is a symbol.
841 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
843 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
845 * async.c (async_pending): Removed declaration.
847 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
849 * dynwind.c (scm_wind_chain): New debug function.
851 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
852 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
853 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
854 extra layer of functions around the body and handler of a thread.
855 This extra layer makes sure that the handler is called in the
856 dynamic context of the surround (= empty dynwind list), but under
857 the *dynamic root* of the body. We can not use the dynamic root
858 of the surround since that root belongs to another thread => stack
859 is not handled correctly. It may seem ugly to use this extra
860 layer, but the extra cost in terms of execution time is really
861 negligible compared to the total amount of time required to create
862 a thread, and it would reduce maintainability to duplicate the
863 crucial and complicated steps performed by cwdr.
865 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
866 (SCM_ALLOW_INTS): Added thread switching code before interrupts
867 get re-enabled. The important effect of this is that interrupts
868 are blocked during thread switching so that thread data structures
869 don't risk getting messed up by an unfortunate signal.
870 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
871 seems to do more aggressive optimization which actually move
872 instructions around in these macros in a fatal way. Therefore:
873 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
874 just superstitious...)
875 (SCM_TICK): Maybe do a context switch and take care of asyncs.
876 This macro should be used instead of SCM_ASYNC_TICK since the
877 latter doesn't do context switches any more.
879 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
880 instead of SCM_ASYNC_TICK.
882 * coop.c, iselect.c: Since thread switches are now performed with
883 interrupts masked, we can't use the old mechanism of delivering
884 signals immediately when they arrive. Signals must instead be
885 delivered when the asyncs run *after* the end of the critical
886 section in scm_internal_select. But this also means after context
887 switch so that the signal will be delivered to a different thread.
888 To avoid this, I have changed the protocol of
889 coop_wait_for_runnable_thread and friends so that they are allowed
890 to return the original thread. So, if a signal arrives during
891 scm_internal_select, we won't any longer be forced do a context
892 switch, but can remain in the same thread and deliver the signal
895 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
896 scm_asyncs_pending and made it global.
898 * iselect.c: Small fixes.
900 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
901 coop_condition_variable_init, coop_condition_variable_wait,
902 coop_condition_variable_signal): Changed return type from `void'
903 to `int'. This is to adhere closer to the pthreads interface.
904 This, in turn, is part of an attempt to provide C versions of the
905 mutex and condition variable primitives which can be part of a
906 frontend to COOP or pthreads.
908 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
909 coop_condition_variable_destroy): New functions.
911 * coop-threads.c (scm_wait_condition_variable): Use
912 coop_condition_variable_wait_mutex.
914 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
915 Definitions moved to coop-defs.h.
917 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
918 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
919 scm_cond_destroy): New C interface to mutecis and cond vars.
921 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
923 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
925 * iselect.c: Now several threads can wait on the same file
926 descriptor. The behaviour is compatible with OS select: All
927 threads waiting for the fd return with the same status.
929 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
931 * coop-threads.c, threads.h (scm_spawn_thread): New function.
932 Can spawn a thread from application C code.
934 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
936 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
937 gh_doubles2scm): New functions.
939 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
941 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
942 commented-out version of gh_eval_str()
944 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
946 * socket.c (scm_bind): free soka after use.
948 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
950 * stime.c (tzvar): new variable.
951 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
952 avoid memory leaks when allocating.
954 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
956 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
959 * gc.c, tags.h: Doc fixes.
961 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
963 * eval.c (macro-eval!): Removed. This function was a design bug.
964 It allowed memoized code to leak out to the scheme level. Most
965 things that you could do with `macro-eval!' can be done with
968 1997-12-20 Tim Pierce <twp@skepsis.com>
970 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
971 scm_fgets now depends on ftell(3) to know how many bytes were
974 1997-12-15 Tim Pierce <twp@skepsis.com>
976 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
977 dealing with strings.
979 1997-12-13 Tim Pierce <twp@skepsis.com>
981 Make %read-line more suitable for implementing read-line efficiently.
982 * ioext.c (scm_read_line): Strip the terminating newline from a
983 string, and return a cons of the string and its terminator.
985 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
986 of the string that is read is stored in this memory location.
987 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
988 * genio.c, genio.h (scm_do_read_line): Update caller.
989 * ports.h (scm_ptobfuns): Update typedef.
990 * fports.c (scm_fptob, scm_pipob): Update struct.
992 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
994 * filesys.c (set_element): Return file descriptor.
995 (fill_select_type): Return the highest file descriptor.
996 (scm_select): Tell select about the highest file descriptor. On
997 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
998 Therefore the extra overhead for calculating the maximum fd seems
999 to be more than compensated. Is this correct? In any case,
1000 scm_internal_select will be much faster with this info.
1001 (scm_select, fill_select_type, set_element): Don't accept any kind
1002 of object in the file descriptor list or vector.
1004 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1006 * iselect.c (finalize_fd_sets): Bugfix.
1008 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1010 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1011 when using scm_internal_select (since we might switch to another
1014 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1016 * simpos.c (scm_system): always define: use sysmissing if not
1017 available. Check for HAVE_SYSTEM instead of _Windows (does
1018 Windows lack system or does it have an unusable one?).
1019 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1020 Let the argument be optional: if not supplied, call system(NULL).
1022 * ports.c (scm_close_port): relax the type check from OPPORTP to
1023 PORTP; closing a closed port is allowed.
1025 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1027 * fports.c (scm_fgets): Return if the last char in a chunk is
1028 newline. When fgets returns a string whose length is `size-1', it
1029 is ambiguous whether a whole line was retrieved, so we must check
1030 explicitly whether a line terminator is present.
1032 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1034 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
1035 before taking the CDR. (Thanks to Harald Meland.)
1037 * filesys.c (scm_stat): Slightly optimized.
1039 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
1041 * ports.c (scm_close_port): Make sure the port is open before
1044 * guile-snarf.in: Pass args through to gcc in a way that preserves

1083 --> the_last_stack_fluid.
1085 * backtrace.c: Added #include "fluids.h"

1115 replacement in iselect.c.
1116 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1117 coop_join): If GUILE_ISELECT enabled, use
1118 coop_wait_for_runnable_thread instead of
1119 coop_next_runnable_thread.
1120 (usleep, sleep): New replacements for system functions if
1121 GUILE_ISELECT is enabled.
1123 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1125 * coop-defs.h (coop_t): Added fields used by scm_internal_select.

1140 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1141 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1142 and scm_must_free, since ultimately the string returned will be copied
1143 by scm_makfrom0str anyway. Also, read any characters that may have
1144 been pushed onto the port with scm_ungetc.
1145 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1146 * ioext.c (scm_read_line): Free string after Guilifying it.

1162 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1163 and to invoke scm_shell().
1164 (gh_launch_pad): took out the loading of boot-9.scm from here,
1165 since it is probably best to let the user control that. In fact,
1166 gh_repl() now invokes scm_shell() which does that.
1168 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1170 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()

1195 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1197 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when

1205 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1207 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1208 OPORT is an `open' port, not an output port.

1217 scm_close_all_ports_except, scm_set_current_output_port,
1218 scm_set_current_error_port): Likewise
1219 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1220 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):

1234 exactly what we want to leave in to detect substrings.
1235 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1236 * tags.h: Fix diagrams and comments describing the S tag bit;
1237 remove vestigial remarks about the D tag bit.

1260 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1262 * gh_data.c (gh_vector_set_x): changed name to make it consistent

1286 complete the picture R4RS functions that should be mirrored in the
1289 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1291 * tags.h (scm_tc7_substring): Changed the comment and code to
1292 conform with the changes below. Folks! We have suddenly two new
1293 free tc7 codes!!! Jummy, jummy!

1357 * gh_test_c.c (c_vector_test): some improvements on the vector
1360 * gh.h (gh_vector): this used to exist but do the wrong thing.
1361 Now it (almost) does the right thing, though it takes a list
1362 instead of the individual arguments. I need to see how it could
1364 (gh_list_to_vector): added this function as a macro. Corresponds
1365 to Scheme's (list->vector ...).

1373 (gh_make_vector): this used to be (stupidly) called gh_vector().
1374 This is the right name, since it does the same thing as the Scheme
1375 (make-vector ...) procedure.

1394 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1396 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1397 macros should by convention not test for NIMPness.)
1398 (SCM_COERCE_OPORT): Adjust indentation.
1400 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added

1424 transformers. (They are always: exp env.); Bugfix: Unmemoize
1425 transformer source with correct environment.

1434 (cwdr_handler): New function.
1435 (scm_internal_cwdr): New function to perform the function of cwdr
1436 but take args that are more useful to C code. Also, the handler
1437 is now invoked *outside* of the new dynamic root, like the docs
1438 say. We no longer have to catch absolutely all errors, the caller
1439 is responsible for using a handler that does not throw, if he
1441 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1442 * root.h (scm_internal_cwdr): New prototype.
1444 Even more but risky streamlining:
1446 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1447 allocation of the jumpbuf of a root continuation. The changes
1448 below are controlled by it. They are now deactivated.
1449 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1450 the JMPBUF of the scm_rootcont to NULL before returning.
1452 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1453 when they are non-NULL.

1471 (scm_free_print_state): Set `revealed' field to false.
1472 (scm_iprin1): Call user supplied closure printer with

1474 one or when it returns #f.
1475 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1476 Accept a port/print-state pair in addition to just a port.
1477 (scm_prin1): Don't return the print_state to the pool when it has
1479 (scm_printer_apply): Set `revealed' field of print_state to true.
1480 (scm_init_print): Set scm_print_state_vtable.
1481 (print_state_fluid, print_state_fluid_num): Removed.

1488 * Makefile.in: Regenerated with automake 1.2c.
1490 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1492 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1493 was looping endlessly.
1495 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1497 * strports.c (scm_eval_string): Don't close the port.
1499 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1500 former returns a nice normal integer. (Thanks to Daniel
1503 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1505 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1506 makefile variable as a build parameter called LIBS. The
1507 build-guile program will use this, for the time being.
1508 * Makefile.in: Regenerated.
1510 Thanks to Shiro Kawai:
1511 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1512 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1515 * Makefile.in: Regenerated with automake 1.2a.
1517 * script.c (scm_compile_shell_switches): If we hit the -c or --
1518 arguments, don't set the car of (command-line) to scm_usage_name,
1519 the prettified name of the guile executable; give it the full
1520 path, the way shells usually handle $0.

1524 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1525 Scheme-level name `array-map' and renamed `serial-array-map' to
1526 `serial-array-map!'.
1528 * backtrace.c: Introduced exception handlers which now enclose
1529 `display-error' and `display-backtrace' so that error reporting
1530 won't get into infinite loops if an error occurs during displaying
1531 of the error. This can very easily happen with user supplied
1532 print call-back routines.
1534 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1536 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1537 the names `serial-array-map' and `array-map' should be removed.)
1539 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1541 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1542 Added #include "objects.h"
1544 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1545 Add #include "feature.h".
1547 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1548 (modinclude_HEADERS): Added objects.h.
1550 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1551 This test is needed at many places in the code and should be
1552 abstracted. (Motivated by the need of this test in libguiletk.)
1554 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1555 (scm_eval_string), load.c (scm_primitive_load,
1556 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1557 Use SCM_EOF_OBJECT_P.
1559 * eval.c (scm_init_eval): Add feature `delay'.
1561 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1563 * scmhob.h: Removed.
1565 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1567 * list.h (SCM_LISTn): New macros. Make list creation in C code
1568 prettier. The idea comes from STk.
1570 * sequences.h, sequences.c, append.h, append.c: Removed. These
1571 files implemented non-R4RS operations which would encourage
1572 non-portable programming style and less easy-to-read code.
1574 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1577 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1578 sequences.h, #include append.h.
1580 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1583 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1585 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1587 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1589 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1591 * eval.c: Added #include "objects.h"
1593 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1596 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1597 adjacent smob numbers.
1599 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1601 * procprop.h: Added declaration of scm_i_inner_name.
1603 * gsubr.c: New global symbol scm_i_inner_name.
1605 * debug.c (scm_procedure_name): Try procedure property
1606 `inner-name' if `name' fails.
1608 * print.c (scm_iprin1): Use scm_macro_name.
1610 * eval.c (scm_m_define): Give names to macros as well; Only the
1611 first top-level definition gives a procedure/macro a name.
1612 Otherwise confusing names can turn up in backtraces.
1613 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1614 `name'; Give names to macros as well.
1616 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1617 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1620 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1622 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
1624 (prinmacro): Removed. The code has been moved/merged into print.c
1625 in order to decrease code redundancy. We want macros to print in
1626 a way equivalent to procedures, and it would be silly to duplicate
1627 the required code. (We don't want to maintain two places.)
1628 (macrosmob): Print field is now a NULL pointer.
1630 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1631 scm_macro_transformer): New prototypes.
1632 (scm_tc16_macro): Declared.
1634 * * print.c (scm_iprin1): Added code for printing of macros. Macros
1635 are now printed in a way equivalent to procedures.
1637 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1639 * procs.h (scm_closure_p): Added declaration.
1641 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1643 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
1644 Shouldn't pass "heap" as the subr name.
1646 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1648 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
1649 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
1650 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1651 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1652 SCM_BOOL_T. Any non-false value is true.
1654 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1656 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1657 scm_gensym): Added prototypes.
1659 * symbols.c (scm_gensym): New function. This will speed up
1660 certain types of applications (such as macro systems) which
1661 generate lots of symbols.
1663 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1665 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
1667 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
1669 * unif.c (scm_shap2ra): tighten the checking of the array dimension
1670 specifier, since (2) or (2 . 3) would cause SEGV.
1671 (scm_transpose_array): more argument checking fixes.
1673 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1675 * Makefile.in: Regenerated.
1677 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1679 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
1681 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1683 * error.c, error.h (scm_error_callback): Removed (see NEWS).
1685 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
1687 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
1688 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
1691 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
1692 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1693 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
1694 scm_array_p, scm_array_rank, scm_array_dimensions,
1695 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
1696 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
1697 scm_array_prototype): Added case scm_tc7_wvect.
1699 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
1701 * errno.h: prototype for scm_strerror.
1702 * error.c (scm_strerror): new procedure.
1704 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1706 * list.c (scm_list_append_x): Allow non-pair as last argument.
1707 This is consistent with the R4RS append and is probably the
1708 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1710 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1712 * stime.h: prototype for scm_times.
1713 * stime.c (scm_times): new procedure.
1714 * ioext.c (scm_fseek): if the first argument is a file descriptor
1716 (scm_ftell): if the first argument is a file descriptor call lseek
1718 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
1719 * filesys.c (scm_chmod): if the first argument is a file descriptor,
1721 (scm_chown): if the first argument is a port or file descriptor,
1723 (scm_truncate_file): new procedure.
1724 Add DEFER/ALLOW INTS to a few other procedures.
1725 (scm_fsync): new procedure.
1726 (scm_open_fdes): new procedure.
1727 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
1729 (scm_fcntl): the first argument can now be a file descriptor. The
1730 third argument is now optional.
1732 * posix.c (scm_execl, scm_execlp): make the filename argument
1733 compulsory, since omitting it causes SEGV.
1734 (scm_sync): return unspecified instead of #f.
1735 (scm_execle): new procedure.
1736 (environ_list_to_c): new procedure.
1737 (scm_environ): use environ_list_to_c. disable interrupts.
1738 (scm_convert_exec_args): take pos and subr arguments and
1739 improve error checking.
1741 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1743 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1744 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1745 argument to SCM_ASSERT. Furthermore, the name of the function
1746 should be passed as first argument when signalling
1747 SCM_WNA. (Thanks to Thomas Morgan)
1749 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1750 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1751 dispatches on the number of actual args has a default case
1752 reporting an internal error. This is a vestige from a version
1753 that mallocated a SCM vector to hold the arguments. In the
1754 current version this check is too late: if it ever happens we will
1755 have already overstepped the bounds of the array.
1757 Also, the patch [...] adds a check for too many actual arguments."
1759 mdj: Removed check for "internal programming error".
1761 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1763 * gh_io.c (gh_write): New function.
1765 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
1766 throw.c (scm_internal_stack_catch): New sibling to the other catch
1767 functions. Code moved from gh_eval.c.
1768 throw.h: Added header.
1769 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
1770 scm_internal_stack_catch.
1772 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1774 * ioext.h: fix up prototypes.
1775 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
1776 Scheme name is now dup->fdes.
1777 (scm_dup_to_fdes): make the second argument optional and
1778 fold in the functionality of scm_primitive_dup.
1779 (scm_primitive_dup): deleted.
1781 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1783 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
1784 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
1785 ultrix are defined. Use setvbuf instead of setbuf.
1786 (scm_setvbuf): new procedure.
1787 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
1788 (scm_setfileno): moved from ioext.c.
1789 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
1790 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
1792 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1794 * fluids.c (scm_fluid_p): New function.
1795 * fluids.h (scm_fluid_p): New prototype.

1799 * print.c (scm_iprin1): Enter printed structures into the print
1800 state as nested data while they are printed.
1801 (print_state_fluid, print_state_fluid_num): New variables.
1802 (scm_init_print): Initialize them.
1803 (scm_iprin): If print_state_fluid carries a print_state, use that
1804 instead of creating a new one.
1805 (scm_printer_apply, apply_stub, struct apply_data): New
1806 definitions to help with calling printer functions written in
1808 * print.h (scm_printer_apply): New prototype.
1810 * struct.c (scm_print_struct): Use scm_printer_apply to call the
1811 user defined struct printer.
1813 * dynwind.c (scm_dowinds): Handle fluids on the wind list.
1814 * fluids.h (scm_internal_with_fluids, scm_with_fluids,

1821 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
1822 SCM_ASSERT: arg comes before pos.
1824 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1826 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
1827 to a list of length zero correctly.
1829 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1831 Supply an `fgets' method for port objects to do fast line i/o.

1833 * genio.c (scm_gen_read_line): New function.
1834 * fports.c (scm_fgets): New function.
1835 (scm_fptob, scm_pipob): Add scm_fgets method.

1845 * ioext.h: removed scm_duplicate_port prototype.
1847 * ioext.c (scm_primitive_dup2): return the new file descriptor
1848 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
1850 (scm_fdopen): bug fix: don't try to make port unbuffered until its
1851 stream has been set.
1852 (scm_duplicate_port): deleted, there's now an implementation in
1854 (scm_primitive_dup2): do nothing if newfd == oldfd.
1856 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
1858 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
1861 * ioext.h: new prototypes.
1862 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
1864 * fluids.c (next_fluid_num): don't do
1865 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
1867 * ports.h: prototypes too.
1868 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
1870 * fports.h: prototype too.
1871 * fports.c (scm_evict_ports): moved from ioext.c.
1873 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
1875 * ports.c (scm_close_port): return a boolean instead of unspecified.
1876 throw an error if an error other than EBADF occurs.
1878 * filesys.h: scm_close prototype.

1880 and ports (scsh compatible).
1882 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
1885 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
1887 * fluids.c, fluid.h: New files.
1888 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
1889 (modinclude_HEADERS): Added "fluids.h"

1897 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
1898 (scm_make_root): Call scm_copy_fluids to make fluid bindings
1899 unique for the new root when it has a parent.
1901 * smob.h: Include "libguile/print.h" to make scm_print_state
1904 * dynl.c (free_dynl_obj): New function to free the dynamic object
1905 data. (dynl_smob): Use it.
1906 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
1907 the dynamic object data below the linking of the object to avoid
1908 memory leak when the linking code throws an error. Now the code
1909 leaks a whole dynamically linked library when must_malloc throws,
1910 but that should be much less likely.
1912 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
1914 Changes to compile under gnu-win32, from Marcus Daniels:
1915 * stime.c (tzset): If tzset isn't provided, make it a NOP.
1916 (scm_localtime): Change SCM_EOF to SCM_EOL.
1917 (scm_mktime): Likewise.
1918 * socket.c: Don't include sys/un.h unless autoconf tells
1919 us Unix domain sockets are available.
1920 (scm_fill_sockaddr): Ignore Unix domain code.
1921 (scm_addr_vector): Likewise.
1922 (scm_init_addr_buffer): Likewise.
1923 (scm_socketpair): Don't include unless socketpair was

1926 * scmsigs.c (scm_pause): Don't include unless pause was found
1928 * posix.c (scm_getgroups): Don't include unless support function
1929 was found during autoconf (in this case, getgroups).
1930 (scm_setpwent): For setpwent.
1931 (scm_setegid): For setegid.
1932 * net_db.c (scm_inet_netof): Don't include unless support
1933 function was found during autoconf (in this case, inet_netof).
1934 (scm_lnaof): For inet_lnaof.
1935 (scm_inet_makeaddr): For inet_makeaddr.

1947 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
1948 scm_misc_error, not SCM_EOF.
1950 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
1951 arguments for formatting the error message, not SCM_BOOL_F. I
1952 think this is left over from the (eq? '() #f) days.
1954 * read.c (recsexpr): Give this a dummy definition if
1955 DEBUG_EXTENSIONS isn't #defined.
1957 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
1959 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
1962 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>

1967 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
1969 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
1970 alloca.lo will be included in @LIBLOBJS@. Something better than
1971 this should be possible.
1972 * Makefile.in: Regenerated.
1974 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1976 * simpos.h: prototype for scm_primitive_exit.
1977 * simpos.c (scm_primitive_exit): new procedure, terminates the
1978 process without unwinding the stack.
1980 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
1982 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
1983 argument and logior its components together, so the user doesn't
1984 have to do this explicitly. Also, if regexp/basic is supplied, then
1985 turn off REG_EXTENDED.
1986 (scm_init_regex_posix): New regexp/basic symbol.
1987 (REG_BASIC): #define this if it is not already present.
1989 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1991 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
1992 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
1993 (CLEANFILES): New target, clean versiondat.h, libpath.h.
1994 (DISTCLEANFILES): New target, clean *.x.
1995 * Makefile.in: Regenerated.

1999 * script.c (scm_compile_shell_switches): Add 1997 to copyright
2000 years in usage message.

2003 * Makefile.in: Regenerated.
2005 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
2006 flag; I don't think we support it.
2007 (scm_make_regexp): Make sure the user doesn't pass the
2010 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
2012 (scm_init_regex_posix): Define constants for the REG_mumble flags;
2013 name them according to the SCSH convention: regexp/mumble.
2015 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
2017 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
2019 * Makefile.am (libpath.h): Include the values of all the standard
2020 Makefile directory variables. Print a message, but don't print
2022 (versiondat.h): Print a message, but don't print all the commands.
2023 * load.c: #include "alist.h".
2024 (init_build_info): New function.
2025 (scm_init_load): Call it.
2026 * Makefile.in: Regenerated.
2028 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
2030 * root.c: Establish a reliable catch-all handler for the new root.
2031 After all the Scheme handler function might signal an error too,
2032 and we don't want to lose that.
2033 (cwdr_inner_body): Renamed from cwdr_body.
2034 (cwdr_outer_body): New function, to establish the user's handler,
2035 and pass control to cwdr_inner_body.
2036 (cwdr): Establish the reliable catch-all handler here, and pass
2037 control to cwdr_outer_body.
2038 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
2039 the user's handler through to cwdr_outer_body.
2040 * throw.c (scm_handle_by_message): Move guts into....
2041 (handler_message): New static function.
2042 (scm_handle_by_message_noexit): New function.
2043 * throw.h (scm_handle_by_message_noexit): New prototype.
2045 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
2046 across this. Only works on GCC. Otherwise, we hope for the best.
2047 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2048 the feeling that real thread systems will not need this...
2050 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2052 Try to detect when people are using one version of libguile and a
2053 different version of ice-9. People have been skewing things and
2054 sending in bug reports.
2055 * Makefile.am (versiondat.h): New file to generate.
2056 * version.c: #include "versiondat.h", to get version info.
2057 (scm_libguile_config_stamp): New function.
2058 * script.c: #include "version.h".
2059 (scm_compile_switches): Call scm_version to get version number.
2060 * scmconfig.h.in, Makefile.in: Regenerated.
2061 * Makefile.in: Regenerated.
2063 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
2064 primitive definitions under their Scheme names.
2066 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2067 1:2. Helps avoid confusion between installed and uninstalled libs.
2069 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2072 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2073 backslash from definition; this should be used like: GDB_INTERFACE;
2075 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2077 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
2078 new port unbuffered until its stream has been set.
2080 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2082 * ports.h: new prototype.
2083 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
2085 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
2087 Make things compile neatly under Sun's C compiler.
2088 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
2089 * extchrs.c (xmbtowc): Make the second arg a normal char, not
2090 unsigned, because that's what the ANSI function takes.
2091 * extchrs.h (xmbtowc): Corresponding change to prototype.
2092 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2094 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2095 argument plain char *.
2096 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2098 * tag.c (scm_tag): Remove unreachable statement.
2099 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2100 top of the word, it should be unsigned.
2102 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2103 is defined, to avoid warnings; it's only used in the
2104 conflict-checking code. Which might go away anyway.
2105 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2106 conditionals; put the label definition in an #if too, to stifle
2109 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2110 ChangeLog-threads in the distribution.
2111 * Makefile.in: Regenerated.
2113 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2115 * guile-snarf.in: Changed regexp to support CPPs that insert
2116 whitespace between lexical tokens (which munges the `%%%' snarf
2119 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2121 * load.c (scm_init_load_path): Append $(datadir)/guile to
2122 %load-path, so modules do not have to be installed in Guile's
2123 current version directory.
2125 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2127 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2128 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2129 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2130 call the sysdep functions with deferred ints.
2131 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2132 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2133 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2136 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2139 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2141 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2143 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2145 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2148 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2150 * eval.c (scm_lookupcar1): New procedure to cope with a race
2151 condition during lookup (when using threads).
2152 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2153 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2156 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2158 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2159 supplied. (Change from Tim Pierce.)
2161 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2163 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2164 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2165 default and not `()'. `#f' is the canonical non-value in Scheme,
2168 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2170 * struct.c (struct_printer): New variable that holds a handle on
2171 the Scheme variable *struct-printer*. This variable can be set by
2172 Scheme code to override the printing of structures.
2173 (scm_print_struct): If struct_printer is set, call it. If it is
2174 not set, or returns #f, print the structure in the old fashion.
2175 Include "eval.h" for scm_apply.
2177 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2179 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2180 scm_struct_i_n_words to get the number of fields, not
2181 -scm_struct_n_extra_words.
2183 On the route to fancier struct printing:
2184 * struct.c (scm_print_struct): New function to print a structure.
2185 Include "genio.h" to support it. This function doesn't do
2186 anything interesting right now, but I think it should be here
2188 * struct.h: Include "print.h" and add prototype for
2190 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2191 print structures ourself.
2193 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2195 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2196 before applying the handler in case it doesn't return.
2198 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2200 * scmsigs.h, async.h: updated.
2202 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2205 * posix.c (scm_uname): interpret only negative values as an error.
2206 Solaris normally returns a positive value.
2208 * script.c (scm_compile_shell_switches): if we are not going into
2209 an interactive repl, set scm_mask_ints to zero so that asyncs can
2212 * simpos.c (scm_system): don't ignore/unignore signals around
2215 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2218 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2219 done in boot-9.scm instead.
2221 * scmsigs.c, async.c: Major rewriting of signal handling code.
2222 (scm_sigaction): new procedure.
2223 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2225 (scm_raise): return unspecified, throw error on failure.
2227 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2229 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2230 feature, to help boot-9.scm decide whether to import the regex
2233 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2235 * eval.c: Include scmconfig.h at the beginning of the file so that
2236 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2239 * regex-posix.c: #include "_scm.h" before conditionally #including
2240 <regex.h>; the former defines HAVE_REGCOMP.
2242 * regex-posix.c: #include <regex.h> conditionally, so the file is
2243 CPP'able (for dependency scanning) even on systems that don't have
2246 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2248 Add new R4RS-compliant syntax for keywords.
2249 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2250 regardless of the setting of the `keywords' read option.
2251 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2252 can be re-read no matter what the setting of the `keywords' read
2255 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2257 Add support for POSIX regular expressions.
2259 * regex-posix.c, regex-posix.h: New files. (Some code
2260 is taken liberally from rx/rgx.c in the old Guile dist.)
2262 * init.c: Include regex-posix.h.
2263 (scm_boot_guile_1): Call scm_init_regex_posix.
2265 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2266 Add regex-posix.[ch] sources.
2267 * Makefile.in: Regenerated.
2269 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2270 to do this automatically? It didn't for me, bleh.)
2272 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2274 * fports.c (print_pipe_port): New function.
2275 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2276 latter doesn't even take the right arguments.
2278 * Makefile.am: Increment shared lib revision number. I think
2279 sometimes the uninstalled Guile finds the installed shared lib;
2280 Gord says doing this might help. As things turned out, I can't
2281 say whether it does.
2282 * Makefile.in: Regenerated.
2284 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2285 passing it as the closure argument to scm_boot_guile. (Bill
2288 * ports.c (print_void_port, putc_void_port, puts_void_port,
2289 write_void_port, flush_void_port, getc_void_port, close_void_port,
2290 noop0): Use ANSI prototypes instead of K&R declarations, so the
2291 initialization of void_port_ptob gets aggressively type-checked.
2292 Fix arguments of print_void_port and write_void_port. (Bill

2326 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2328 * script.c (scm_find_executable): Use prototype-style definition
2329 here; apparently it's not quite right to have const in a prototype
2330 and then use a K&R declaration. I wonder if stuff like this will
2331 go away if we compile with -Wrequire-prototypes, or whatever that
2332 is... (Bernard URBAN)
2334 * scmhob.h: New text from Bernard URBAN.
2336 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2338 * script.c: Don't #define const on hpux. Configure takes care of
2339 this. (Thanks to Larry Schwimmer.)
2341 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2342 decide whether to #include <unistd.h>, instead of listing a bunch
2343 of systems. Don't #include stdio twice. Removed dyked-out
2344 definition of scm_find_impl_file.
2346 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2348 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2349 library version info to 1:0.
2350 * Makefile.in: Regenerated.
2352 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

2356 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2357 throw.c: Update copyright years; these files have been worked on
2358 significantly in 1997, but only had copyright years for 1996.
2359 Also, change name of copyright holder on some from Mikael
2360 Djurfeldt to Free Software Foundation; he has signed papers
2361 assigning the changes to the FSF.
2363 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2364 reason not to give the user the option.
2366 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2367 Return #f on end-of-file when scanning table (i.e. when called
2368 with no arguments). Try to catch errors, when we can.
2369 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2371 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2372 external declarations. These are useful.
2374 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2376 * posix.c: don't include <sys/select.h> or define macros for
2377 select, since they were not used in this file.
2379 * filesys.c (scm_select): make the fifth parameter microseconds,
2380 not milliseconds. let the fourth parameter be either a real value
2381 or an integer or #f. The first, second and third arguments can
2382 now be vectors: the type of the corresponding return set will be
2384 (set_element, get_element): new static procedures.
2386 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2388 * strports.c (scm_eval_string): New function.
2389 (scm_eval_0str): Trivially re-implemented in terms of
2391 * strports.h (scm_eval_string): New extern decl.
2393 * net_db.c (h_errno): Add extern decl for this.
2395 * fports.c (local_pclose): New function.
2396 (scm_pipob): Use it in the initializer here.
2399 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2400 Use a meaningful error message when signalling an error. For
2401 this, scm_gethost must check h_errno rather than errno.
2403 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2405 * Makefile.in: Regenerated, using automake-1.1p.
2407 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2409 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2410 not SCM_UNSPECIFIED.
2412 * script.c (scm_compile_shell_switches): don't append (quit) if
2414 (scm_shell): call scm_exit_status and exit on the result of the
2417 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2419 Ensure that shared substrings are handled properly when passed to
2420 a system call or other foreign function. Many thanks to Tim
2422 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2423 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2424 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2425 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

2442 * error.c (scm_error): Add newline to error message.
2444 * init.c (scm_init_standard_ports): Doc fix.
2446 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2448 * dynl-shl.c: Completely replaced with new code from Bernard
2451 * script.c (scm_ice_9_already_loaded): New variable.
2452 (scm_compile_shell_switches): Use it.
2454 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2456 * filesys.c (scm_input_waiting_p): add missing third argument to
2459 * stime.c (scm_localtime): copy the result of localtime before
2460 calling gmtime in case they share a buffer.
2461 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2464 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2466 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2468 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2470 * Makefile.am (check-local): New target, which causes 'make check'
2471 to run gh_test_c and gh_test_repl, with some trivial input.
2472 * Makefile.in: Rgnrtd.
2474 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2476 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2479 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2481 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2482 sure how this was supposed to work.
2483 (scm_async_click): don't send SCM_TICK_SIGNAL.
2484 (scm_init_async): don't initialize %tick-thunk.
2486 * the following change doesn't affect the Scheme interface:
2487 gc-thunk is called at the end of garbage collection. however it's
2488 no longer implemented by pretending it's a signal.
2490 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2491 system async corresponding to scm_gc_thunk.
2492 * async.h: declare scm_gc_async.
2493 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2494 gc-thunk directly, instead of going through a signal handler.
2495 (scm_gc_async): new variable, points to the GC system-async.
2496 (scm_init_async): save the GC async as scm_gc_async instead
2497 of using system_signal_asyncs.
2498 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2500 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2502 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2503 Don't screw up if we're interrupted.
2504 * Makefile.in: Regeneradet.
2506 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2508 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2510 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2511 we're not using AM_INIT_GUILE_MODULE any more.
2512 * Makefile.in: Reneregated.
2514 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2516 Functions for finding variable bindings, grace à Tim Pierce.
2517 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2518 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2520 Get 'make dist' to work again.
2521 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2522 * Makefile.in: Regenerated, like a surry without a fringe on top.
2524 Changes for reduced Guile distribution: one configure script,
2526 * configure.in, configure: Removed.
2527 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2528 real configure script lives.
2529 * Makefile.in, scmconfig.h.in: Regenerated.
2531 * init.c: #include "script.h", to get prototype for script.c's
2534 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2536 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2537 scm_must_malloc, not raw malloc.
2539 * script.c (scm_compile_shell_switches): Dyke out debugging output
2542 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2544 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2546 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2547 system has them. Hope this is safe. Previously
2548 sys/timeb.h was included if HAVE_FTIME was defined or if
2549 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2550 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2552 * ioext.c (scm_setfileno): add missing third argument to
2553 scm_misc_error call.
2555 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2557 * eq.c (scm_equal_p): Correctly compare strings of different
2558 varieties. (Thanks to Tim Pierce.)
2560 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2562 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2563 #! block comment must occur on a line all by itself.
2565 Move most of the guts of shell command processing into libguile,
2566 so guile.c can be very small (and eventuallly auto-generated. (I
2567 mean, generated mechanically, not self-generated. Hmm.))
2568 * guile.c, script.c, script.h: New source files.
2569 * init.c (scm_boot_guile_1): Call scm_init_script.
2570 * libguile.h: #include "script.h".
2571 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2572 targets, for new executable.
2573 (libguile_la_SOURCES): Mention script.c.
2574 (modinclude_HEADERS): Add script.h.
2575 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2576 not dynamic linking is enabled. This is because we're generating
2577 executables now. Move CY_AC_WITH_THREADS call after those, so the
2578 values of cy_cv_threads_libs captures the libs chosen above.
2579 * Makefile.in, configure, aclocal.m4: Regenerated.
2581 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2582 We don't maintain this interface any more, and it just confuses
2585 * alloca.c: #include <scmconfig.h>, not <config.h>.
2586 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2587 it'll get included in disties.
2589 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2591 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2592 be distributed, because they confuse people.
2593 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2595 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2597 * configure.in: check for presence of gethostent (not present on
2598 OpenBSD by default).
2599 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2600 * configure, scmconfig.h.in: Regenerated.
2602 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2604 * backtrace.c (scm_backtrace): Split message string across
2605 newlines properly. GCC is more tolerant of this than other

2610 Merge threads directory into libguile.
2611 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
2612 threads.h: New source files.

2614 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2616 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2617 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2618 coop-threads.c.cygnus, coop-threads.h.cygnus.
2619 * configure.in: If we're using threads, include threads.o in
2621 * _scm.h, libguile.h: threads.h lives in this directory now.
2622 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2623 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2624 currently used, but brought along for information's sake.
2625 * ChangeLog-threads: log from old 'threads' directory.
2626 * Makefile.in, configure: Rebuilt.
2628 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2630 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2633 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2635 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2637 Merge GH interface library into libguile.
2638 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
2639 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2640 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2641 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2643 (EXTRA_libguile_la_SOURCES): ... here.
2644 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2645 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2646 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2647 New variables, describing how to build the gh test programs.
2648 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2649 build the test programs, and we probably should have been linking
2650 libguile.la against them all along, to support AIX shared libs.
2651 Add cflags for threads to CFLAGS; add libs for threads to new
2652 variable THREAD_LIBS, used in Makefile.am.
2653 * ChangeLog-gh: log from old `gh' subdirectory.
2654 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2656 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2658 * acconfig.h: Undo change of Apr 9; including the definition of
2659 PACKAGE in the guile headers conflicts with applications' own
2661 * scmconfig.h.in: Regenerated.
2663 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

2670 when PROC is receiving no arguments.
2672 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2674 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2675 have S_IFSOCK. This is the case under Ultrix.
2677 * posix.c (scm_status_exit_val, scm_status_exit_val,
2678 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2679 Ultrix versions of WIFSTOPPED, etc., which assume that their
2680 arguments are lvalues (hmm).
2682 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2684 * eval.c: Doc fixes.
2686 * throw.c: Doc fixes; rearranged.
2688 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
2690 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
2692 * acconfig.h: Added entry for PACKAGE.
2693 * scmconfig.h.in: Regenerated.
2695 Changes to work with automake-1.1n, which has better libtool support.
2696 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2697 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
2699 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
2701 * Makefile.in: Rebuild.
2703 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2705 * stime.c (scm_mktime): take an optional zone argument.
2706 (scm_localtime): check putenv return value.
2707 (scm_strftime, scm_strptime): moved from posix.c. move #include
2709 stime.h, posix.h: update prototypes.
2710 (bdtime2c, setzone, restorezone): new static procedures.
2711 (scm_mktime, scm_strftime): use them.
2712 (scm_strftime): don't call mktime before strftime. Use
2713 filltime for return value.
2714 (filltime): convert NULL zname to #f.
2715 (scm_strptime): return a count of characters consumed, not
2716 the remaining string.
2718 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2720 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
2721 (scm_mktime): likewise.
2723 Uncomment localtime and mktime.
2725 * configure.in: add AC_STRUCT_TIMEZONE.
2727 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2729 * stime.c (scm_init_stime): don't define ticks/sec.
2730 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2731 return value problem and is still portable.)
2733 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2735 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2736 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2737 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2738 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2739 cpp_err_symbols.c): Corresponding changes.
2740 * Makefile.in: Regenerated.
2742 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2744 * posix.c (scm_putenv): don't check HAVE_PUTENV.
2745 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
2746 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
2747 * putenv.c: new file, from sh-utils 1.12.
2749 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2750 since allocation isn't for Scheme objects.
2751 (scm_putenv): copy strings before placing in the environment.
2753 * stime.c (scm_current_time): throw an error if time returns -1,
2754 instead of returning #f.
2755 (scm_get_internal_real_time, scm_get_internal_real_time): use
2756 scm_long2num for return value instead of SCM_MAKINUM.
2758 * stime.h: prototypes updated.
2760 * stime.c (scm_time_in_msec): apparently unused, deleted.
2762 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2764 * configure.in: check for gettimeofday.
2766 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2767 which may be more usefully portable than a gettimeofday interface.
2769 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2771 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not

2775 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2777 * stime.c (filltime): recovered static procedure.
2778 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
2781 * posix.h: add prototype for scm_close_pipe, remove prototypes for
2782 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2784 * posix.c (scm_mknod): split the mode argument into type and perms
2785 arguments, like the extra fields returned by stat.
2787 * fports.c (scm_pipob): set the close, free and print procedures.
2788 (scm_close_pipe): new procedure.
2790 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2791 define them in boot-9.scm
2793 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2795 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
2796 wan't defined. Don't include fd.h.
2798 * Previously fd.h was regenerated whenever configure was run,
2799 forcing a couple of files to be recompiled.
2801 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
2802 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
2803 Check for _fileno as well as _file.
2805 * ioext.c: don't fd.h.
2806 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
2809 * Change the stratigy for getting information about errno
2810 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
2811 generating lists of symbols during the build process, which will
2812 not always work, include comprehensive lists in the distribution.
2813 To help keep the lists up to date, the "check_signals" and
2814 "check_errnos" make targets can be used.
2816 * configure.in: don't check for a command to extract errno codes.
2817 * Makefile.am: update file lists, remove errnos.list and errnos.c
2818 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
2819 check_errnos targets.
2820 (CLEANFILES): remove errnos.c and errnos.list, add
2821 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
2822 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
2823 * errnos.default: deleted.
2824 * cpp_signal.c: new file.
2825 * cpp_errno.c: renamed from errnos_get.c.
2826 * cpp_err_symbols, cpp_sig_symbols: new files.
2827 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
2828 * error.c (scm_init_error): #include cpp_err_symbols instead of
2830 * posix.c (scm_init_posix): don't intern signal symbols. #include
2833 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
2835 * strop.c (scm_i_index): allow the lower bound to be equal to the
2836 length of the string, so a null string doesn't always give an error.
2838 * posix.h: new prototypes.
2839 * posix.c (scm_status_exit_val, scm_status_term_sig,
2840 scm_status_stop_sig): new functions, as in scsh. They break down
2841 process status values as returned by waitpid.
2843 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
2845 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
2846 configure doesn't know about it.
2848 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2850 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
2852 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
2853 which defines C variables with global linkage.
2855 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2857 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
2860 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
2862 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
2863 has time to check why this doesn't work well with continuations.
2865 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
2867 * Fix shell syntax error; some shells won't tolerate
2868 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
2870 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2872 * posix.c (scm_uname): throw an error if uname fails instead
2875 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
2877 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
2880 * async.c (scm_ints_disabled): definition moved from error.c.
2882 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2884 * acconfig.h: Removed PACKAGE.
2886 * scmconfig.h.in: Regenerated.
2888 * snarf.h: g++ says it's non-portable not to specify the first
2889 argument in a varargs declaration. I introduced the first
2890 argument by using preprocessor conditionals.
2892 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
2894 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
2895 (scm_freopen): use RO string macros for filename and modes.
2896 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
2898 * posix.c (scm_getgrgid): simplify conversion of name to C string.
2899 (scm_mknod): use RO string macros for path.
2901 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
2902 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
2904 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2905 use SCM_ROSTRINGP and SCM_ROCHARS.
2907 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2909 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
2912 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
2913 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
2914 support for byte vectors.
2916 * print.c (scm_iprin1): Limit number of vector elements printed
2917 according to pstate->length.
2919 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2921 * backtrace.c (scm_display_error_message): don't segv if message
2924 * error.h: prototype for scm_error_scm.
2926 * error.c (scm_error_scm): new procedure, reimplements scm-error
2927 in C and uses scm_error.
2929 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2931 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
2932 pointer to the Scheme variable read-hash-procedures and intern it
2933 in scm_init_read. Modify scm_read_hash_extend and
2934 scm_get_hash_procedure to use the pointer.
2936 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2938 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
2939 (SCM_KEYWORD_STYLE): defined.
2941 * read.c (scm_read_opts): add a keywords option. This isn't a
2942 boolean option, in case someone wants to add support for DSSSL
2944 Setup scm_keyword_prefix symbol.
2945 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
2947 I've left keyword support disabled by default, since it doesn't
2948 seem to break the module system and it gives R4RS standard behaviour.
2949 It can be reactivated with (read-set! keywords 'prefix).
2951 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2953 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
2954 before constructing arbiter.
2956 * eval.c (scm_m_define): Bugfix: Check that the object is a
2957 closure before setting the procedure property!
2959 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
2961 * ports.c: Removed `ungetc-char-ready?'.
2963 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
2965 * read.c (scm_init_read): intitialise scm_read_hash_procedures
2966 (idea from Mikael: make it a pair so scm_permanent object only
2968 (scm_read_hash_extend): don't call scm_permanent_object.
2969 (ideas from Mikael): if chr is already in the list, replace its
2970 procedure instead of appending it again. If proc is #f, remove
2972 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
2974 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
2976 * gdbint.c (gdb_read): update scm_lreadr usage.
2978 * load.h: update prototypes.
2980 * load.c (scm_primitive_load, scm_read_and_eval_x,
2981 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
2983 * read.h: add prototype for scm_read_hash_extend. Change args for
2986 * read.c (scm_read_hash_procedures): new variable.
2987 (scm_read_hash_extend): new procedure.
2988 (scm_get_hash_procedure): new procedure.
2989 (scm_lreadr): use scm_get_hash_procedure instead of an argument
2990 for extended # processing.
2991 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
2992 scm_read_token): remove case_i, sharp arguments. Change callers.
2994 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
2996 * read.h (SCM_N_READ_OPTIONS): increase to 3.
2997 (SCM_CASE_INSENSITIVE_P): define.
2999 * read.c: add case-insensitive option to scm_read_opts.
3000 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
3001 to determine whether to convert symbol case.
3002 (default_case_i): definition removed.
3003 * read.c (scm_read_token): if case_i, downcase ic before doing
3006 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3008 * configure.in: Added configuration option `guile-debug'.
3009 Configure with --enable-guile-debug if you want a bunch of extra
3010 functions used for debugging when developing Guile.
3012 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3014 * procs.c (make-cclo): New undocumented debugging procedure: Make
3015 compiled closure with internal procedure PROC and length LENGTH.
3016 Only compiled if GUILE_DEBUG is defined.
3018 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3020 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3022 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3024 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3025 with 3 or more args internally to the evaluator.
3027 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3029 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3030 with 3 or more args internally to the evaluator. This is mainly
3031 because we don't want to pass entry and exit points of the
3032 debug support twice, but it also seems to increase the speed of
3033 the evaluator for such calls (e. g. (+ 1 2 3)).
3035 * backtrace.c (scm_display_application): New procedure:
3036 display-application; Set fancy printing parameters individually
3037 for different types of display (backtrace, error, application).
3038 (These should of course be customizable!)
3040 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3041 clear the CHECK-flags.
3043 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3045 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3047 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3049 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3050 from pairs with a GLOC in the car.
3052 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3053 otherwise `symbol-hash' will behave badly.
3054 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3055 we get segmentation fault!
3057 * symbols.c: Added #include "weaks.h". New functions:
3058 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3059 moved to an extraneous library when we split libguile.)
3061 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3063 * filesys.c (scm_stat): stat now takes fport arguments too as
3064 documented in the manual.
3066 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3068 * debug.c (scm_single_step): Bugfix: Call continuation with
3069 scm_call_continuation instead of throwing to it.
3071 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3073 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3074 argument wasn't declared to be optional.
3076 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3078 * stime.c (scm_init_stime): Add feature "current-time".
3080 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3082 * throw.h: prototype for scm_exit_status.
3083 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3084 args to derive an exit status. Allows (quit) to work from a
3086 (scm_exit_status): new function.
3089 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3091 * eval.c (scm_deval): Removed some old code.
3092 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3094 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3097 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3100 * procs.c: Introduce the existent C function scm_thunk_p at the
3101 Scheme level as well.
3103 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3105 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3106 used from C to easily lookup the value of a symbol in the current
3109 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3111 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3112 scm_init_unif in this file. This will also fix a previous problem
3115 * configure.in: Added AM_MAINTAINER_MODE
3117 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3119 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3122 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3124 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3125 source files that are not always included in libguile but should
3126 have their dependencies calculated by automake. This variable is
3127 recognized by automake, no further magic is needed.
3128 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3129 to deal exclusively with *.lo files, as it seems. The *.o files
3130 are built automatically when the corresponding *.lo file gets
3133 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3135 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3138 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3140 * unif.c (scm_array_set_x): minor change to argument error checking.
3142 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3144 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3145 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3146 They should only be included in the library at configure.in's
3148 (libguile_la_LDADD): Include the appropriate .lo files here.
3149 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3150 so we know when to build them (and their .lo bretheren).
3151 * configure.in (LIBLOBJS): New substituted variable. We let
3152 configure decide which .o files to include in LIBOBJS, and then
3153 put the corresponding list of .lo files in LIBLOBJS. The latter
3154 is what we pass to libtool.
3155 * Makefile.in, configure: regenerated.
3157 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3159 * symbols.c (scm_sysintern0): New function. Contains the core of
3160 old scm_sysintern but doesn't take a second value argument.
3161 (scm_sysintern): Now uses scm_sysintern0.
3162 (scm_sysintern_no_module_lookup): Renamed to
3163 scm_sysintern0_no_module_lookup and doesn't take a second value
3164 argument any longer.
3166 * symbols.h (scm_sysintern0: Added declaration.
3168 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3169 scm_sysintern when interning option keys. Otherwise we risk
3170 destroying the values of already interned variables.
3172 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3173 scheme-level boolean (use SCM_NFALSEP).
3175 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3177 (scm_backtrace): New function. (C version of old function from
3178 boot-9.scm) Motivation: Make it possible to display backtraces
3179 without depending on boot-9.scm. (I'm uncertain if this
3180 motivation is good enough...)
3182 * root.h (scm_root_state): Add member the_last_stack_var.
3183 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3185 * root.c (mark_root): Mark scm_the_last_stack_var.
3187 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3190 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3192 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3193 1. mark_lazy_catch didn't mark the smob.
3194 2. Both functions above have standard variants:
3195 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3196 free_lazy_catch --> scm_free0.
3198 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3200 * throw.c (scm_internal_lazy_catch): New function.
3201 (scm_lazy_catch): Rewritten to use it.
3202 (scm_ithrow): Handle the new lazy catch representation.
3203 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3204 that doesn't have a jmpbuf is a lazy catch clause.
3205 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3206 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3207 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3209 (scm_init_throw): Register the new lazy-catch smob type.
3210 * throw.h (scm_internal_lazy_catch): decl for new function.
3212 * throw.c (scm_internal_catch): Doc fixes.
3214 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3215 configure.in. Including this might cause problems if applications
3216 that link against libguile include their own copies of alloca, but
3217 if they're using autoconf, they should be adding libguile to LIBS
3218 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3219 the copy in libguile, and things will be okay. (I think.)
3221 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3223 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3225 strop.h: move prototypes too.
3227 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3229 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3232 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3233 etc. I deleted them from filesys.c long ago, but didn't
3234 notice they were here too (although ineffective since
3235 sys/stat.h wasn't included).
3237 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3239 * eval.c: Don't define alloca in GCC case. gcc will automatically
3240 use __builtin_alloca if appropriate.
3242 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3244 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3245 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3246 that values of automatic variables are preserved. See comments
3247 for safe_setjmp for details.
3249 Change from Thomas Morgan:
3250 * variable.c: Include eq.h.
3251 (var_equal): New function.
3252 (variable_smob): Use var_equal as the discriminator for variables.
3254 * throw.c (s_throw): Remove extraneous declaration.
3256 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3257 * eval.c: Add necessary CPP cruft to support that.
3258 * configure, Makefile.in, scmconfig.h.in: regenerated.
3260 Change from Thomas Morgan:
3261 * procprop.c (scm_procedure_properties): Convert the Scheme
3262 boolean returned by scm_procedure_p into a C boolean before using
3263 it as a condition for SCM_ASSERT.
3264 (scm_procedure_property): Likewise.
3266 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3267 indications of Unixness.
3270 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3272 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3274 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3276 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3277 "unknown # object" error messages.
3279 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3280 (scm_i_index) and declare it static. Add a 'direction' argument
3281 to indicate what way the search should go.
3282 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3284 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3285 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3287 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3289 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3291 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3292 to avoid clash with various scsh forks.
3294 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3296 The following two changes (ramap.c, throw.c) are motivated by the
3297 apparent unportability of forward declarations of static arrays of
3298 the form `static foo bar[];'.
3300 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3301 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3303 * throw.c (scm_throw): Moved above scm_ithrow.
3305 * options.h: Removed the extern declarations of scm_yes_sym and
3306 scm_no_sym since these are static.
3308 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3310 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3312 * Makefile.am: remove AWK=@AWK@.
3313 Add a rule for generating errnos.list.
3314 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3316 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3317 don't extract errnos, just set a variable (avoids the
3318 need to recompile error.c just because configure is run.)
3320 * unif.h: update prototypes.
3321 * unif.c (scm_uniform_array_read,write): change the offset and
3322 length arguments to start and end, for consistency.
3324 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3326 * ioext.h: update prototypes.
3327 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3328 scm_read_line_x, it's a more general procedure using an
3329 interface from scsh. read-line and read-line! are now defined
3331 Note that the new read-line trims the terminator
3332 by default, previously it was appended to the returned string. An
3333 optional argument specifies how to process the terminator (scsh
3334 compatible). For the old behaviour: (read-line port 'concat).
3335 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3336 returns a pair, but is converted to multiple values if the scsh
3339 socket.h: update prototypes.
3340 * socket.c (scm_recvfrom): for consistency with other procedures,
3341 take start and end as separate optional arguments.
3342 (scm_recv, scm_recvfrom): don't allow the second argument
3343 to be a size, only a buffer. Change the scheme names to
3344 recv! and recvfrom!. Don't return the buffer.
3346 * ioext.h, posix.h: move prototypes too.
3347 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3348 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3349 "read.h" and "unif.h".
3350 * ioext.c: include "chars.h"
3352 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3354 * dynl.c: The dynamic linking and module registration functions
3355 are now defined even when dynamic linking is not available for the
3356 host system. Some of their functionality can be done without
3357 dynamic linking; when it's really needed, they throw errors.
3359 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3361 * configure.in: Only define DYNAMIC_LINKING when one of the system
3362 dependent functions is detected.
3363 * dynl.c (scm_dynamic_func): New function to get the address of a
3364 function in a dynamic object.
3365 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3366 produced by scm_dynamic_func as the thing to call.
3368 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3370 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3371 (scm_register_module_xxx, scm_registered_modules,
3372 scm_clear_registered_modules): New functions.
3374 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3376 * symbols.c (scm_sysintern): Renamed to
3377 scm_sysintern_no_module_lookup.
3378 (scm_sysintern): New function to take the place of the old
3379 scm_sysintern. It uses the current toplevel lookup closure to give
3380 the symbol its value. This is a temporary hack to put packages
3381 like gtcltk into their own module.
3382 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3383 us whether `scm_top_level_lookup_closure_var' has been initialized
3385 * eval.c (scm_init_eval): Set it.
3387 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3389 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3390 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3392 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3394 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3395 scm_sys_dup): deleted: FD capability will be added to other
3397 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3398 scm_fd_free, fd_smob, scm_intern_fd.
3399 (scm_open): renamed from scm_sys_open. Return a port instead of
3400 an FD object. Make the mode argument optional.
3401 (scm_sys_create): deleted, it's just a special case of open.
3402 (scm_init_filesys): move interning of constants O_CREAT etc.,
3403 here (were previously using SCM_CONST_LONG macro).
3404 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3406 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3407 include "fports.h" and <stdio.h>
3408 (scm_stat, scm_select): don't support FD objects.
3410 * error.h: adjust scm_syserror_msg prototype.
3411 * error.c (scm_syserror_msg): take an extra argument for errno.
3412 Using the global value didn't always work, since it could be
3413 reset by procedure calls in the message or args arguments.
3415 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3416 I don't understand why the check was there (and what about the
3419 * strop.c (scm_string_copy): allow shared substrings to be copied.
3421 * unif.h: corresponding change to prototypes.
3422 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3423 recognize two new optional arguments: offset and length. Allow
3424 the port argument to be an integer (file descriptor, for scsh).
3425 Include <unistd.h> for "read" prototype.
3427 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3429 * socket.c: don't include filesys.h.
3431 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3433 * Makefile.am: add AWK=@AWK@ (?)
3435 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3437 Add a rule to generate errnos.c from errnos.
3438 * error.c (scm_init_error): include errnos.c.
3439 * errnos_cnvt.awk: new file, converts the list of errno codes to
3441 * errnos_get.c: new file.
3442 * errnos.default: new file, contains errnos to try if they can't
3443 be extracted from errno.h.
3444 * configure.in: if using GCC, try and extract errno codes from
3448 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3450 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3451 * Makefile.am: Made libguile into a libtool library.
3452 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3453 Set libtool_libs to indicate that libguile is a libtool library.
3454 See guile/ChangeLog for details.
3455 * .cvsignore: ignore "*.lo", the libtool library objects.
3457 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3459 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3460 use htons in getservbyport argument.
3462 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3464 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3465 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3468 * objprop.c (scm_object_property): No need to take the CDR of the
3469 value returned by scm_object_properties, since Aug 20 change.
3471 * configure.in: When checking for struct linger, #include
3472 <sys/types.h> as well as <sys/socket.h>. I've never known
3473 <sys/types.h> to cause any portability problems, and Solaris's
3474 <sys/socket.h> needs it.
3475 * configure: Rebuilt.
3477 I think the Sun compiler has chosen a perverse way to interpret
3478 ANSI declarations combined with K&R definitions. We'll
3479 appease it a little bit. But when it invades France, we fight.
3480 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3481 * print.h (scm_iprlist): Here too.
3482 * numbers.c (scm_divbigdig): Change definition to match
3483 declaration in numbers.h.
3484 * unif.c (scm_makflo): Change definition to match declaration in
3487 * init.c (scm_boot_guile): Don't return the value of
3488 scm_boot_guile_1. This function doesn't return a value;
3489 scm_boot_guile_1 doesn't return a value (or return at all).
3491 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3494 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3495 compile. I have a feeling this function is a bad idea anyway ---
3496 one should always test for features, not systems.
3498 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3499 semicolons. Only pure luck kept this from being noticed earlier.
3501 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3503 * socket.c (scm_recvfrom): Added missing semicolon.
3505 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3507 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3508 the buffer and start and end positions for scsh networking
3511 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3513 * configure.in: Revert previous change to this file; the problem
3514 is due to transient automake weirdness.
3515 * configure: Rebuilt.
3517 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3518 PLUGIN/guile.libs. configure generates the latter from the former.
3519 * Makefile.in: Rebuilt.
3521 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3522 need this if we install scripts, like guile-snarf.
3523 * configure: Rebuilt.
3525 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3527 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3529 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3531 * socket.c (scm_addr_vector): fix faulty scm_listify.
3533 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3535 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3536 style block comment is no longer considered an error.
3538 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3540 * PLUGIN/guile.libs.in: New file.
3541 * PLUGIN/guile.libs: Removed from repository.
3542 * configure.in: Create PLUGIN/guile.libs from
3543 PLUGIN/guile.libs.in. This is for including additonal libraries
3544 needed for dynamic linking.
3545 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3546 instead of PLUGIN/guile.libs.
3548 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3550 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3552 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3553 occurrences of the given element from the list, not just the
3554 first. This is how the Emacs Lisp functions behave, how the
3555 analogous Common Lisp functions behave, and (I believe) how the
3556 older Maclisp functions worked. I realize that this change may
3557 break code, but it seemed better to break it before the Guile
3560 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3561 Their prototypes were already present in gc.h, but they weren't
3563 (scm_init_storage): Initialize scm_protects.
3564 * root.c (scm_protects): New element of scm_sys_protects.
3566 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3568 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3570 * libguile.h: Added #include "libguile/net_db.h".
3572 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3573 30 change. That file is only meant for communication between the
3574 configuration process and load.c. If code linked against libguile
3575 wants to get at the paths mentioned in libpath.h, it can call
3576 functions declared in load.h.
3578 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3580 * libguile.h: Removed #include "libguile/fdsocket.h"
3582 * net_db.c: Added #include <sys/socket.h>.
3584 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3586 * filesys.c (scm_input_waiting_p): use select in preference to
3587 FIONREAD, since the latter doesn't detect EOF.
3588 Throw error if neither select nor FIONREAD available.
3590 * socket.c (scm_connect): take a port, not a fd object.
3591 (scm_fill_sockaddr): throw an error if fam is not recognised.
3592 (scm_bind): use scm_fill_sockaddr.
3593 (scm_listen): take a port, not a fd object.
3594 (scm_accept): take and return a port. return #f in the car if
3595 address can't be got
3596 (scm_sock_fd_to_port): new procedure.
3597 (scm_socket): use scm_sock_fd_to_port.
3598 (scm_addr_vector): throw error if unrecognised address type.
3599 take an extra argument with the calling procedure name.
3600 (scm_getsockname): take a port. return #f if address can't be got.
3601 (scm_getpeername): take a port. return #f if address can't be got.
3602 (scm_recvfrom): take a port. return #f for address component if can't
3604 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3605 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3607 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3609 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3610 use separate data pointers, to allow them to be designed
3611 independently and reused.
3612 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3613 Renamed from catch_body, catch_handler, and uncaught_throw; made
3615 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3617 (scm_catch): Use the above.
3618 (scm_throw): Don't bother printing a message for an uncaught
3619 throw; we establish a default handler in init.
3620 * throw.h (scm_internal_catch): Prototype updated.
3621 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3623 (struct scm_body_thunk_data): New structure, used as data
3624 argument to scm_body_thunk.
3625 * init.c (struct main_func_closure): New structure, packaging up
3626 the data to pass to the user's main function.
3627 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3628 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3629 scm_internal_catch to establish a catch-all handler, using
3630 scm_handle_by_message. This replaces the special-case code in
3632 (invoke_main_func): Body function for scm_internal_catch; invoke
3633 the user's main function, using the main_func_closure pointer to
3634 decide what to pass it.
3635 * root.c (struct cwdr_body_data): Remove handler_proc member.
3636 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3637 (cwdr_handler): Removed.
3639 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3641 * socket.h (SCM_P): update bind prototype.
3642 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3643 include "feature.h".
3644 (scm_socket): return a port, not a file descriptor object.
3645 include "fports.h" and <unistd.h>
3646 (scm_bind): take a port, not a file descriptor object.
3647 take an extra argument for address args.
3649 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3650 INADDR_NONE, INADDR_LOOPBACK.
3652 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3654 * init.c: include net_db.h and not fdsocket.h.
3655 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3657 * Makefile.am: corresponding changes.
3658 * socket.h: renamed from fdsocket.h, fix names.
3659 * net_db.h: renamed from socket.h, fix names.
3660 * socket.c: renamed from fdsocket.c.
3661 remove _sys from procedure names.
3662 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3663 add "socket" to features list.
3664 * net_db.c: renamed from socket.c.
3665 remove _sys from procedure names.
3666 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3667 add "net-db" to features list.
3668 include "net_db.h". don't include <sys/socket.h> or
3671 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3673 * tags.h (scm_tags): Removed comma at end of last enumerator.
3675 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3677 Don't use GCC extensions to allocate space for debugging frames.
3678 (Here he goes again! Why do we put up with this?!)
3679 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3680 an scm_debug_info structure, not an in-line array of them. Add
3681 'info' member, to say how many vect elements we've used, for eval
3683 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3684 a new variable debug_info_end to mark the end of vect, instead of
3685 the address of the 'info' pointer itself.
3686 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3687 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3688 (SCM_APPLY): Explicitly allocate space for debug.vect.
3689 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3690 * stacks.c: Adjusted for new debug frame structure.
3691 (RELOC_INFO, RELOC_FRAME): New macros.
3692 (stack_depth, read_frames): Use them, and new scm_debug_frame
3693 element 'info', instead of magically knowing that eval frames have
3694 an info pointer sitting after vect.
3695 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3697 (scm_init_stacks): Formatting tweaks.
3699 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3701 Give GCC more control flow information, so it can be sure that
3702 variables aren't used uninitialized.
3703 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3704 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3705 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3706 scm_misc_error): Tell GCC that these functions never return.
3707 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3708 out the field type, call abort if SCM_ASSERT returns, to placate
3710 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3711 scm_wta ever returns. We can't handle this case anyway, and this
3712 gives the optimizer more information.
3713 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3714 scm_wta ever returns.
3716 In some cases, the code is fine, but GCC isn't smart enough to
3717 figure that out; this usually happens when one variable is only
3718 initialized and used when a particular condition holds true, and
3719 we know that condition will never change within a given invocation
3720 of the function. In this case, we simply initialize the variables
3721 to placate the compiler, hopefully to a value which will cause a
3722 crash if it is ever actually used.
3723 * print.c (scm_iprin1): Initialize mw_pos.
3724 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3725 * throw.c (scm_ithrow): Initialize dynpair.
3726 * unif.c (scm_uniform_vector_ref): Initialize cra.
3727 * struct.c (init_struct): Initialize prot.
3728 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3730 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3731 if EXPR contains no expressions.
3733 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3735 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3736 cause an infinite loop (???). So much for the algebraic
3737 equivalency of variable-sized arrays and alloca...
3739 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3741 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3742 a SCM boolean, not a C boolean.
3744 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3746 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3747 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3748 rules for raising scm_mtrigger. Previously, unfortunate but not
3749 unlikely circumstances could result in almost constant invokation
3750 of the gc. Now, this situations should be less likely, but they
3751 are not prevented completely.
3753 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3755 * numbers.c (scm_fuck): Procedure removed; looks like old test
3757 * numbers.h: Prototype removed.
3759 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3761 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3762 array to a pointer, to match my Nov 21 change in eval.c.
3764 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3766 * libguile.h: Added #include "libguile/backtrace.h", #include
3767 "libguile/stacks.h".
3769 * strings.c (scm_string scm_make_string scm_string_ref
3770 scm_string_set_x scm_string_equal_p scm_string_append):
3771 Bugfix according to scm patch from Aubrey Jaffer:
3772 Corrected long-standing
3773 (not (eqv? (integer->char 128)
3774 (string-ref (make-string 1 (integer->char 128)) 0)))
3775 bug found by John Kozak <jk@noontide.demon.co.uk>.
3777 * strports.c, strports.h: Make scm_eval_0str return the value of
3778 the last expression evaluated (previously, it returned void).
3780 * strports.c, strports.h: New function: scm_read_0str. Does what
3783 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3785 * simpos.c (scm_getenv): return #f if string can't be found in the
3786 environment instead of throwing an exception, for compatibility
3787 with numerous other systems.
3789 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3791 * Makefile.am (.c.x): Use guile-snarf.
3792 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
3794 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
3796 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3798 * backtrace.c (scm_display_error_message): Made non-static, and
3799 renamed from display_error_message.
3800 * backtrace.h (scm_display_error_message): Added extern decl.
3801 * throw.c (uncaught_throw): Use it to display the error message.
3803 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
3805 * inet_aton.c: Use #if 0, not #ifdef 0.
3807 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
3809 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
3810 to convert the returned value.
3811 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
3812 the offset argument.
3814 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3816 Add new interface to catch/throw, usable from C as well as
3818 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
3819 (scm_internal_catch): New function, replaces...
3820 (scm_catch_apply): Deleted.
3821 * throw.c (scm_catch_apply): Deleted; replaced with a more general
3822 mechanism which is a bit more code, but can be used nicely from C
3823 and implement the Scheme semantics as well.
3824 (scm_internal_catch): This is the replacement; it's named after
3825 the analogous function in Emacs.
3826 (scm_catch): Reimplemented in terms of the above.
3827 (struct catch_body_data, catch_body, catch_handler): New
3828 functions, used by scm_catch.
3829 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
3830 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
3831 support for new cwdr.
3833 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
3836 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
3838 * acconfig.h: Added DYNAMIC_LINKING symbol.
3839 * configure.in: Add option and checks for dynamic linking.
3840 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
3841 dynl.h: New files for dynamic linking support.
3842 * Makefile.am (libguile_a_SOURCES):
3844 (modinclude_HEADERS): Added "dynl.h".
3845 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
3847 * init.c (scm_boot_guile_1): Call
3848 scm_init_dynamic_linking to initialize dynamic linking support.
3850 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
3852 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
3853 (as we Schemers say). It needs to be global, so that I can tweak
3854 it for the proper operation of unexec.
3855 (scm_boot_guile_1_live): New variable, see above.
3857 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
3859 * guile-snarf.sh: Removed.
3860 * PLUGIN/guile.libs: Added dependency for -lm.
3861 * acinclude.m4: Renamed from aclocal.m4.
3862 * PLUGIN/greet: Removed.
3863 * Makefile.am, aclocal.m4: New files.
3864 * configure.in: Updated for Automake.
3866 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
3868 * eval.c (scm_definedp): Use top_level_lookup_closure_var
3869 and not top_level_lookup_thunk_var.
3871 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
3873 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
3875 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
3877 * eval.c (scm_definedp): Incompatibly changed to be a builtin
3878 Scheme function, instead of syntax. Single argument is now a
3881 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3883 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
3884 scm_ra_divide): Properly terminate statements passed as arguments
3885 to IVDEP macros. (Thanks to Bernard Urban.)
3887 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
3888 with non-constant sizes. (Thanks to Bernard Urban.)
3890 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3892 It's an "eval closure", not an "eval thunk." A thunk is a
3893 function of no arguments.
3894 * root.h (struct scm_root_state): Renamed
3895 top_level_lookup_closure_var from top_level_lookup_thunk_var.
3896 (scm_top_level_lookup_closure_var): Renamed from
3897 scm_top_level_lookup_thunk_var.
3898 * root.c (mark_root): Uses changed.
3899 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
3900 * init.c (scm_start_stack): Uses changed.
3901 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
3902 Change scheme-visible name to *top-level-lookup-closure* from
3903 *top-level-lookup-thunk*.
3905 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
3907 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
3908 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
3910 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
3912 * gc.c (struct scm_heap_seg_data): Doc fixes.
3914 * gc.c (scm_gc_sweep): Empty all segments' freelists before
3915 sweeping. Then, prepend each segment's free cells to its
3916 freelist, rather than wiping out the old value. (Thanks to Marius
3919 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
3920 scm_check_freelist, scm_debug_newcell): New functions and
3921 variables, for debugging freelist problems.
3922 * pairs.h (SCM_NEWCELL): New debugging version added.
3923 * gc.h (scm_debug_newcell): Added extern declaration, used by
3924 debugging version of SCM_NEWCELL.
3926 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3928 On some systems <libc.h> conflicts with <unistd.h>, and should not
3929 be #included at all.
3930 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
3931 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
3932 * configure.in: Call it.
3933 * posix.c, filesys.c: Use its results to decide whether or not to
3935 * configure, scmconfig.h.in: Rebuilt with autoconf and
3938 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
3940 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
3941 pointer to the stdio stream before calling scm_setbuf0, so the
3942 latter will be able to retrieve it. I'm surprised this didn't
3943 segfault earlier. (Thanks to Christopher Lee.)
3945 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3947 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
3950 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3952 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
3953 number of stack narrowing specifier pairs. The first specifier in
3954 a pair controls inner border, the second the outer border. A
3955 number means cut that number of frames, a procedure object means
3956 cut until that object is found in operator position in a frame.
3958 * root.c (cwdr): Bugfix.
3960 * read.c: Recording of positions disabled by default.
3962 * procs.c (scm_closure_p): New function.
3964 * posix.c (scm_tmpnam): New function.
3966 * load.c: Added #include "throw.h".
3967 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
3970 * load.c, load.h (scm_read_and_eval_x): New function.
3972 * eval.c: Renamed debug option "deval" to "debug".
3974 (scm_eval_x): `eval!' is no longer accessible from the scheme
3975 level. Motivation: We can't allow operations which introduce
3976 glocs into the scheme level. Guile's type system can't handle
3977 these as data. Use `eval' or `read-and-eval!' as replacement.
3979 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
3980 SCM_CONSP since this is a macro!; Set vframe.prev to
3981 scm_last_debug_frame instead of 0. In this way we can look
3982 "above" the virtual start stack frame if we wish.
3983 (scm_debug_hang): New function: Useful for debugging Guile in
3984 certain tricky situations. Will probably be removed later...
3986 * debug.h: Changed semantics of debug option "backtrace". This
3987 option now only indicates whether we want automatic backtrace at
3990 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3992 * ports.c: #include "filesys.h"
3993 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
3995 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
3996 Motivation: This is system specific code which is related to file
3997 I/O. It also may use select. Added code by Gary Houston to
3998 detect presence of character in stdio buffers.
4000 * libguile.h: #include "libguile/libpath.h"
4002 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4003 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4004 SCM_SITE_DIR; Install libpath.h among the other include files.
4006 * load.c, load.h (scm_sys_package_data_dir): New function.
4008 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4010 * stacks.h: Bugfix: Don't use tail-array length field as stack
4011 length field! This screwed GC.
4013 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4015 * _scm.h: Added #ifndef around definition of macros min and max.
4017 * __scm.h: Added hooks for threads to plugin to in ints protection
4018 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4019 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4020 the main code in these macros duplicated and spread over multiple
4021 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4022 SCM_THREAD_SWITCHING_CODE.
4024 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4026 * snarf.h: New file.
4027 * guile-snarf.sh: New file.
4028 * Makefile.in (inner_h_files): Added snarf.h
4029 (ancillary, install, uninstall, distclean): Added actions for
4031 (.c.x): Use guile-snarf.
4032 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4033 (gen_c_files): Note that these depend on guile-snarf.
4034 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4035 now in "snarf.h". Added #include "snarf.h" to get them.
4036 * libguile.h: Added #include "snarf.h".
4037 (Patches applied and tweaked by Jim Blandy.)
4039 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4041 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4042 standards suggest against providing prototypes for system
4043 functions. Thanks to Greg Troxel.
4045 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4047 * strports.c (scm_eval_0str): New function.
4048 #include "read.h", to get prototype for scm_read.
4049 * Makefile.in (strports.o): Update dependencies.
4050 * strports.h: New prototype.
4052 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4053 scheme name from "int?" to "integer?". It seems to do the job.
4054 * numbers.h: Rename prototype too.
4055 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4058 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4059 scm_num_eq_p): Rename these according to R4RS conventions: call
4060 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4061 to making libguile R4RS compliant without ice-9...
4063 * load.c (scm_sys_search_load_path): Search for files under all
4064 extensions listed in the %load-extensions variable. If FILENAME
4065 is absolute, return it unchanged, without searching the load path.
4066 (scm_loc_load_extensions): New variable, pointing to
4067 %load-extensions' value cell.
4068 (scm_init_load): Initialize it, and the value it points to.
4069 (scm_primitive_load_path): Improve error reporting.
4071 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4072 of new Scheme variable %load-hook.
4073 (scm_primitive_load): Apply %load-hook to filename.
4075 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4077 * configure.in: add tests for figuring out whether buffered data
4078 is available in a FILE structure, which is needed by char-ready.
4080 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4083 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4084 exceptions using misc_error instead of syserror. It seems a bit
4085 odd to throw an exception if a string can't be found in the
4086 environment, but it's consistent with open-file, stat etc.
4087 (simpos.h): remove sys_ from getenv.
4089 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4090 occurs, throw an error instead of returning errno. Return value
4092 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4094 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4096 * filesys.c (scm_stat2scm): derive file type and permissions from
4097 the stat mode and append them to the returned vector.
4098 There isn't much overhead in doing this and it avoids the need to
4099 work with S_IRUSR et al. in Scheme.
4100 Define symbols scm_sym_regular etc.
4101 (scm_init_filesys): don't intern S_IRUSR etc.
4103 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4104 and s_primitive_load_path.
4106 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4108 * error.h: don't declare error symbols. prototype for scm_misc_error.
4110 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4113 * error.c: use SCM_SYMBOL to set up error keys.
4114 scm_misc_error: new procedure.
4116 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4118 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4119 between `#!' and `!#' is ignored.
4120 (skip_scsh_block_comment): New function.
4122 * feature.c (scm_set_program_arguments): New argument, FIRST.
4123 * feature.h: Update prototype.
4124 * init.c (scm_boot_guile_1): Pass new argument to
4125 scm_set_program_arguments.
4127 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4129 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4130 (scm_boot_guile): Call scm_set_program_arguments here, later than
4131 the old initialization.
4133 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4134 initialization procedure.
4135 - Delete in, out, err arguments; there are other perfectly good
4136 ways to override these when desired.
4137 - Delete result argument; this function shouldn't ever return.
4138 - Rename init_func argument to main_func, for less confusion.
4139 - Delete boot_cmd argument; main_func is more general.
4140 -Add 'closure' argument, to help people pass data to main_func
4141 without resorting to global variables.
4142 - Abort if reentered; don't bother returning an error code.
4143 - Call scm_init_standard_ports to set up the default/current
4144 standard ports; no need to pass them to scm_start_stack.
4145 - Remove code to evaluate the boot_cmd, and start the repl; let
4146 the user do something like that in main_func if they want.
4147 - Remove code to package up a return value; main_func can do any
4149 - Call exit (0), instead of returning.
4150 (scm_start_stack): Don't initialize the I/O ports here; that's
4151 weird. Delete in, out, err arguments. Move guts to
4152 scm_init_standard_ports, scm_stdio_to_port.
4153 (scm_init_standard_ports): New function, to set up current and
4154 default standard ports.
4155 (scm_start_stack, scm_restart_stack): Make these static.
4156 * init.h (scm_boot_guile): Adjust declaration.
4157 (scm_start_stack, scm_restart_stack): Remove externally
4158 visible declarations for these.
4159 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4161 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4162 written out several times in scm_start_stack.
4163 * fports.h: New declaration for the above.
4165 * feature.c (scm_set_program_arguments): New function.
4166 * feature.h: New declaration for the above.
4168 * ports.c: Formatting tweak.
4170 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4172 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4173 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4174 for obtaining the address of a car or cdr field. Motivation:
4175 &SCM_CXR make assumptions about the internal structure of the
4178 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4179 Motivation: see SCM_CXRLOC.
4181 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4182 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4183 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4184 Motivation: Safer use. Some other macros are defined in terms of
4185 these operations. If these are defined using the SCM_SETCXR
4186 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4187 to inefficiency and an <e1> with side-effects could potentially
4188 break. Also, these particular operations are heavily utilized in
4189 the garbage collector. In unoptimized code there will be a
4192 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4193 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4194 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4195 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4196 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4197 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4198 vports.c: Cleaned up use of pairs: Don't make any special
4199 assumptions about the internal structure of selectors and
4200 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4201 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4202 (Among other things, this change makes it easier to build Guile
4203 with certain compilers which have problems with casted lvalues.)
4205 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4207 * stacks.c: Improve selection of relevant stack frames when making
4208 a stack object. Introduce one level of indirection in the stack
4209 object to make it possible to "narrow" to a certain region of the
4210 stack. This facilitates making use of more clever algorithms (not
4211 implemented) for selecting relevant frames and gives a cleaner
4212 design since selection of frames can be done independently of
4213 extraction of frames from the real stack.
4214 (scm_stack_id): Also take #t as argument which means look at
4217 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4218 Turn n_tail into an integer directly representing current number
4219 of frames in stack. Add field tail.
4221 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4223 * debug.c (scm_make_memoized): Made it available at scheme level.
4224 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4225 SCM_NIMP before applying heavier predicates in argument checking.
4226 (scm_local_eval): Also take memoized object as argument.
4228 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4229 aren't created with zero length, but should such a strange
4230 creature suddenly turn up...
4232 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4234 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4235 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4237 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4239 * variable.c (scm_make_variable): Make the name hint optional, as
4241 (anonymous_variable_sym): Renamed from variable_sym. All uses
4244 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4245 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4246 of scm_primitive_load_path was also changed to
4247 "primitive-load-path", from "%try-load-path". Callers changed.
4248 We'd like to respect the convention that a function named
4249 "try-mumble" should behave just like the function called "mumble",
4250 but return #f instead of signalling some error.
4251 * load.h: Rename prototypes.
4253 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4255 * print.c (make_print_state, grow_print_state), print.h: Modified
4256 the print state representation: Don't use a tail array for
4257 recording of circular references. Resizing of the print state
4258 structure invalidates the print state pointer. To avoid passing
4259 around an indirect print state reference to all printing
4260 functions, we instead let the print state reference a resizable
4263 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4265 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4266 Don't crash when passed an improper list terminated by a
4267 non-immediate value.
4269 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4271 Allocate data for structures on an eight-byte boundary, as
4272 required by the tagging system.
4273 * struct.c (alloc_struct): New function.
4274 (scm_make_struct, scm_make_vtable_vtable): Call it.
4275 * struct.h (scm_struct_n_extra_words): Bump to 3.
4276 (scm_struct_i_ptr): New "field".
4277 * gc.c (scm_gc_sweep): When we need to free the data, use the
4278 information stored by alloc_struct to find the beginning of the
4279 block allocated to the structure, so we can free it.
4281 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4283 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4286 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4287 (scm_debug_info): New member: id.
4289 * stacks.c: Stacks are now represented as structs; Stacks have an
4290 id given to them by `start-stack'.
4291 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4293 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4294 Changed stack representation.
4296 * debug.c (scm_procedure_name): Try procedure property `name' for
4297 compiled closures aswell.
4299 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4301 * eval.c: scm_i_name moved to gsubr.c
4302 (scm_m_define): Record names of all kinds of procedure
4303 objects. (Earlier, only closures were recorded.)
4305 * procprop.h: Added declaration of scm_i_name.
4307 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4308 (scm_make_gsubr): Record names of compiled closures.
4310 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4312 * debug.c, debug.h: Removed obsolete code.
4314 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4315 stacks.c: Renamed regs --> scm_contregs.
4317 * print.c (scm_free_print_state): Cleanup print state before
4318 returning it to pool. It is better to do it here than in
4319 scm_prin1 since scm_prin1 is called often.
4321 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4322 s_set_source_property_x): Check that first argument is a pair or a
4325 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4326 scm_i_line, scm_i_column and scm_i_breakpoint global.
4328 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4329 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4332 * debug.h: Added debug object smob declaration and macro
4335 * configure.in: Build with backtrace.o and stacks.o if debug
4338 * Makefile.in: Added entries for new files: backtrace.c,
4339 backtrace.h, stacks.c and stacks.h.
4341 * symbols.c (scm_sym2ovcell): Fixed documentation.
4343 * _scm.h (min, max): Added.
4345 * async.c: Moved `min' macro to _scm.h.
4347 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4348 SCM_BACKTRACE_INDENT.
4350 * eval.c: Added new debug options `maxdepth' and `indent'.
4352 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4354 * print.h: Added selector SCM_PRINT_STATE.
4356 * print.c: New functions: scm_make_print_state,
4357 scm_free_print_state.
4359 * print.h: Added declarations for scm_make_print_state,
4360 scm_free_print_state.
4362 * debug.c (scm_m_start_stack): New acro.
4364 * debug.h: Small cleanup.
4366 * init.c (scm_boot_guile_1): Moved scm_init_debug below

4391 declare functions with prototypes. (Patch thanks to Marius
4394 More prototype-related changes from Marius Vollmer:
4395 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4396 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4397 * ports.h (ptobfuns): Added prototypes. This means some casting in
4399 * fports.c: Added casts for initializations, since the functions
4400 are defined to take FILE * as their stream argument, not SCM.
4401 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4402 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4403 to `char *str_data' to conform to prototype.
4405 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4407 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4409 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4411 * stime.c, stime.h: use SCM_P method.
4413 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4415 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4416 be given at least two arguments. Insist that lst's last element
4417 be a list, but don't make any requirements of its predecessors.
4419 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4421 * eval.c (scm_nconc2last): Revert last change; there seems to be
4422 other stuff going on here.
4424 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4426 * eval.c (scm_nconc2last): Make sure that each element of lst
4427 (which is a list of argument lists, except for the tail) is a
4428 proper list, i.e., finite and terminated by '().
4430 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4432 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4435 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4436 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4439 * vectors.c (scm_make_vector): Fill vectors with the undefined
4440 value, to help make Guile Scheme code more portable to other
4443 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4444 * symbols.h, tags.h: Doc fixes.
4446 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4448 * async.c (scm_take_signal): Doc fixes.
4450 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4452 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4453 want to subtract it from the modulus; we just want to leave it
4456 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4458 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4461 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4463 * throw.c (scm_catch_apply): Finished implementation of
4466 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4468 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4470 (scm_init_filesys): set "i/o-extensions" feature.
4473 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4475 * Makefile.in (root.o): Correct dependencies.
4477 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4479 * Makefile.in: Added dependency entry for root.o.
4481 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4482 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4484 * init.c (scm_start_stack): Set initial root continuation number
4487 * procs.c: New function: scm_thunk_p.
4489 * procs.h: Added declarations of scm_thunk_p.
4491 * root.c: Renamed `call-with-new-root' -->
4492 `call-with-dynamic-root'.
4493 (cwdr): Removed allocation of new root state. This should be done
4494 separately by use of scm_make_root.
4495 (scm_apply_with_dynamic_root): New function: Does what it
4496 sounds like. Needed when spawning threads.
4498 * root.h: Added member last_debug_frame to root state.
4499 Added #include "libguile/debug.h"
4501 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4502 arguments. The motivation is that code in root.c needs catch
4503 functionality, and we want to avoid code duplication.
4504 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4505 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4506 handlers that run without popping the stack into the dynwind
4509 * throw.h: Added prototypes for scm_catch_apply and
4512 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4514 * root.h (scm_root, scm_set_root): Decouple thread support details
4515 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4516 SCM_SET_THREAD_LOCAL_DATA.
4518 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4519 and tortoise scanning loop.
4521 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4523 * Makefile.in: Rebuild dependencies.
4525 * libguile.h: #include "libguile/print.h" before "smob.h", since
4526 the latter uses the print_state structure.
4528 * throw.c (scm_ithrow): Use the correct variable when checking to
4529 see if a given element of scm_dynwinds is a valid catch.
4531 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4532 structure, abort; don't just silently ignore the garbage.
4534 * _scm.h: #include "print.h" here, since it seems to be used just
4536 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4537 strports.c, unif.h: Don't #include "print.h".
4539 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4541 * feature.h (scm_loc_features): Removed external declaration.
4542 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4544 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4546 * feature.c (scm_init_feature): Added threads feature (needs to be
4547 initialized here, since features doesn't exist when
4548 scm_init_threads is called).
4550 * libguile.h: Added #include "libguile/../threads/threads.h".
4551 (This is a kludge to get thread support working. This should be
4554 * configure.in, acconfig.h: Added flags for thread support.
4556 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4559 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4560 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4563 * _scm.h: Added conditional #include "threads.h"
4565 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4566 SCM_THREADS_SWITCHING_CODE.
4568 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4569 allocate the basic dynamic root object.
4570 (scm_boot_guile): Added call to scm_init_root.
4572 * root.c, root.h: Added root smob.
4573 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4574 functions: Implements dynamic roots mostly according to spec in
4575 SCM manual. Main difference is that the second argument is a
4576 throw handler rather than an error "thunk".
4578 * root.h: Added declaration of scm_init_root.
4580 * root.c: Added #include "genio.h", #include "smob.h", #include
4581 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4583 (scm_init_root): Added #include "root.x".
4585 * throw.c: Added #include "stackchk.h"
4586 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4587 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4588 can be used in scm_call_with_new_root; Added reenabling of stack
4589 checking when catching a throw.
4591 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4593 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4595 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4596 element is not found, as per R4RS.
4598 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4600 * list.c: Doc fixes throughout.
4602 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4604 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4605 declare the char * to be const. Avoids a warning in rgx.c.
4607 * ports.h: spelling fix.
4609 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4612 * load.c (scm_sys_try_load_path): throw an error if file not found
4613 (like it says it in NEWS).
4615 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4617 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4618 PROPS slot to '(), not #f; it's an empty alist.
4620 * throw.h, throw.c: Use SCM_P instead of #if hair.
4622 Remove special support for uncaught throws; see throw.c for
4624 * throw.c (uncaught_throw): New function.
4625 (scm_ithrow): Call uncaught_throw if we don't find a throw
4626 target; don't mess with scm_bad_throw_vcell.
4627 (scm_bad_throw_vcell): Variable deleted.
4628 (scm_init_throw): Don't initialize it.
4630 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4633 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4635 * numbers.c (scm_istr2int): If the number is short (as most
4636 numbers are), just call scm_small_istr2int to deal with it.
4637 (scm_small_istr2int): New function, created by un-#ifdefing the
4638 non-bignum version of scm_istr2int and renaming it.
4640 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4642 * load.c (scm_sys_try_load): don't check whether value returned
4643 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4644 Change the Scheme name from %try-load to primitive-load.
4646 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4647 Can avoid passing a message, allowing it to be derived in the
4648 error handler (e.g., if we want to throw to the key both from
4651 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4653 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4654 references now have a new appearance which is more compact and
4655 also gives a clue about what the target of the reference is.
4656 By setting parameters in the print state, more fancy printing can
4657 be achieved. This is used by the (not yet commited) backtrace
4660 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4662 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4665 * print.c: Added #include "struct.h". Removed function
4668 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4669 scm_iprin1. Removed prototype for scm_prlist.
4671 * arbiters.c (prinarb),
4672 async.c (print_async),
4673 debug.c (prindebugobj, prinmemoized),
4674 eval.c (prinprom, prinmacro),
4675 filesys.c (scm_fd_print, scm_dir_print),
4677 mallocs.c (prinmalloc),
4678 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4679 smob.h (scm_smobfuns),
4680 srcprop.c (prinsrcprops),
4682 unif.c, unif.h (scm_raprin1, rapr1),
4683 variable.c (prin_var): Changed argument `int writing' to
4684 `scm_print_state *pstate'.
4686 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4687 that it will be called before scm_init_print.
4689 * print.c (scm_prin1): Print states are now allocated when calling
4690 scm_prin1 and then passed around to all printing functions as an
4691 argument. A cache `print_state_pool' enables reuse of print
4693 (scm_make_print_state): New function.
4694 (scm_iprin1): Adaption to print states.
4695 (scm_iprlist): An initial "hare and tortoise" scan brings down
4696 time complexity to O (depth * N). (Better time complexity will be
4697 achieved when the printing code is completely rewritten.)
4699 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4701 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4702 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4703 it gets done whether or not the cache variable has a value.
4705 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4707 Distinguish #f and ().
4708 * __scm.h: #undef SICP.
4709 * pairs.h (SCM_EOL): Delete this definition, equating it with
4711 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4712 the value it used to have. Doc fixes, too.
4714 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4716 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4717 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4718 Lord's implementation of structs, allowing for tail arrays as
4719 described in the manual. Also fixed some bugs. (Both the interface
4720 and the implementation should be improved.)
4722 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4724 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4725 People who whish to see the source can do `(print-enable 'source)'.
4726 Removed #ifdef DEBUG_EXTENSIONS.
4728 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4730 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4731 integer (assuming for now accepting an integer is a good thing).
4733 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4734 %S will be used instead for write'ing arguments.
4736 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4737 asserts. fix a few other asserts.
4738 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4739 scm_uniform_vector_ref, scm_array_set_x,
4740 scm_dimensions_to_unform_array): change args in
4741 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4742 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4743 scm_substring_fill_x): likewise.
4744 gsubr.c (scm_gsubr_apply): likewise.
4745 eval.c (SCM_APPLY): likewise.
4747 * eval.c (4 places): replace scm_everr with lgh_error or
4750 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4751 scm_memory_error): new procedures.
4752 scm_everr: deleted. can use scm_wta, dropping first two args.
4753 scm_error: convert NULL subr to SCM_BOOL_F.
4755 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4758 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4761 * error.c, error.h: new error keys: scm_arg_type_key,
4762 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4764 scm_wta: reimplement using lgh_error instead of scm_everr.
4766 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4768 * gdbint.c: scm_lread now has one more argument.
4770 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4771 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4772 loading source from non-file ports, which, e. g., happens when
4773 using the Emacs interface).
4775 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4778 * read.c: Added code for recording of positions of source code
4779 expressions; New functions: recsexpr, scm_lreadrecparen;
4780 _scm_make_srcprops --> scm_make_srcprops
4781 (scm_flush_ws): Removed updating of positions counters. This work
4782 is already done by scm_gen_getc
4784 * read.h: Added prototype for scm_lreadrecparen
4786 * print.c: Added #include "alist.h"
4788 * eval.c: Added #include "hash.h"
4790 * eq.c: Added #include "ramap.h"
4792 * options.c: Documentation fixes.
4794 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
4795 (scm_init_srcprop): Adjusted size of initial source-whash. Name
4796 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
4797 --> scm_make_srcprops
4799 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
4800 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
4801 function calls in the definition of the whash access macros.
4803 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
4805 * init.c (scm_boot_guile): Add level of indirection to
4806 scm_boot_guile_1() to ensure that stack base pointer is properly
4807 initialized. There was no guarantee that variable i was the
4808 highest/lowest variable on stack (i.e. the call frame of
4809 scm_boot_guile was not completely protected from gc).
4811 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
4813 * ports.h (scm_port_table): put back file_name, it will be used to
4814 support debugging. Undo related changes in fports.c, ioext.c,
4817 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4819 * ports.h (scm_port_table): remove file_name member for now, it seems
4821 * fports.c (scm_open_file): don't set file_name in PTAB.
4822 (prinfport): don't use file_name in PTAB.
4823 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
4824 * ports.c (scm_add_to_port_table): don't intialize file_name.
4825 (scm_port_file_name): remove for now.
4826 * gc.c (scm_gc_mark): don't mark PTAB file_name.
4828 * fports.h (scm_mkfile): prototype deleted.
4829 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
4831 * debug.c, unif.c: use scm_out_of_range instead of
4832 wta for range errors (ASSERT still needs work).
4834 * error.c, error.h (scm_out_of_range): new procedure.
4836 * error.c, error.h (scm_out_of_range_key): new key.
4838 * posix.c (scm_sync): #else was missing.
4840 * error.c, error.h: append _key to names scm_num_overflow and
4843 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
4844 of consing an empty list.
4845 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
4846 of macros, saves code and string space.
4847 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
4848 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
4849 lower case. Rename scm_syserror_m to scm_syserror_msg.
4850 error.h: prototypes for new procedures.
4852 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
4854 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
4856 * error.c, error.h: setup scm_num_overflow key.
4858 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
4859 Remove definition of SCM_OVSCM_FLOW.
4861 * fports.c (scm_open_file): use SCM_SYSERROR_M.
4863 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
4864 explicit message and args.
4866 * error.c, error.h, __scm.h: change system_error_sym to
4869 * error.c (system_error_sym): remove leading %% from the Scheme name
4872 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
4874 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4876 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
4877 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
4878 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
4879 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
4880 renamed. (These were introduced by unsupervised name
4883 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4885 * print.c: Added code for detection of circular references during
4886 printing. (init_ref_stack, grow_ref_stack): New functions. Added
4887 a hook for printing of closures (accessible via print options).
4888 This leads to a split of calls to scm_iprin1 into two classes:
4889 elementary print operations (e. g. the code which prints a smob)
4890 still use scm_iprin1 while top level calls (like scm_display) use
4891 scm_prin1. scm_prin1 begins by clearing the data structure used
4892 to record reference information.
4894 * print.h: Added declarations of scm_prin1 and scm_prlist.
4896 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
4898 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
4900 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
4902 * error.c (err_head): scm_iprin1 --> scm_prin1
4904 * debug.c: Adjusted header comment.
4908 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4910 * strerror.c: Doc fix.
4912 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4914 * gdbint.c (gdb_read): Now possible to run during GC.
4915 (unmark_port, remark_port): New functions.
4917 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
4919 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
4920 of allocating a new string object. Also, increase size by
4921 the factor 2 instead of 1.5.
4923 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
4925 * __scm.h (SCM_P): Corrected to run under traditional C.
4927 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
4930 * async.c: Calls to scm_sysintern corrected.
4932 * async.h (scm_async_clock): Redundant declaration removed.
4934 * continuations.c (scm_dynthrow): Redundant declaration removed.
4936 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
4937 Definition typos corrected.
4939 * debug.h: Missing declarations of functions in debug.c added
4942 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
4943 Missing declarations to functions in eval.c added.
4945 * filesys.c: Possibly uninitialized variable rv.
4947 * gc.h (scm_object_addr, scm_unhash_name): Missing
4948 declarations of functions defined in gc.c added.
4950 * genio.c: Possible typos str_data -> wstr_data. ???
4952 * genio.c: Possibly unintended shadowing of local variable
4953 `int c' (gotos out of scope of inner `c'). ???
4955 * init.c: Uninitialized `SCM last' may be used.
4957 * ioext.h: (scm_sys_isatty_p): Typo.
4959 * list.h (scm_list_head): Missing prototype for function in
4962 * numbers.c (scm_two_doubles): Changed from extern to static
4963 (is used only within numbers.c).
4965 * numbers.h: Repeated declarations removed.
4967 * ports.h (scm_close_all_ports_except): Declaration for the
4968 function defined in ports.c added.
4970 * posix.h: Missing declarations added.
4972 * procs.h (scm_make_subr_opt): Missing declaration added.
4974 * socket.h (scm_sys_gethost): Missing declaration added.
4976 * socket.h: Redundant declarations removed (they are in fdsocket.h).
4978 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
4979 Missing declarations added.
4981 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
4983 * struct.c: Uninitialized variable `SCM answer' may be used.
4985 * unif.c (l2ra): Declaration prototype.
4987 * unif.c (scm_array_equal_p): Dummy definition removed (it is
4988 defined in ramap.c).
4990 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
4991 Redundant declarations removed (they are in ramap.h).
4993 * variable.h (scm_make_udvariable,
4994 scm_make_undefined_variable): Declaration corrected to
4995 correspond variable.c.
4997 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
4998 Missing declarations added.
5000 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5002 * Makefile.in (distclean): Don't forget to delete fd.h.
5004 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5006 * fd.h.in, tags.h: Trivial cleanups.
5008 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5009 marksweep.h just declared functions from gc.c.
5010 * gc.h, libguile.h: Don't #include "marksweep.h".
5011 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5012 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5013 dependencies updated.
5015 * libguile.h: Don't #include "files.h"; it's been deleted.
5017 * files.c (scm_sys_delete_file): Moved to filesys.c.
5018 File is now empty; deleted.
5020 * filesys.c: scm_sys_delete_file is now here. Remove
5021 #if's; they seem to rely on remnants of an old portability
5022 regimen. If the problems come up again, solve them properly,
5023 using autoconf. Specifically: Don't test M_SYSV, and #define
5024 remove to be unlink if it's #defined; don't use remove just
5025 because HAVE_STDC_HEADERS is #defined.
5026 * filesys.h: Add declarations for scm_sys_delete_file.
5027 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5028 files.o, files.h, files.c, and files.x.
5029 * init.c: Don't #include "files.h", and don't call scm_init_files.
5031 Use SCM_P instead of PROTO; the latter intrudes on the user's
5033 * params.h: Deleted; definition of SCM_P moved to...
5034 * __scm.h: ... here, where it replaces PROTO macro.
5035 * libguile.h, smob.h: Don't #include "params.h".
5036 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5037 smob.h: Fix prototypes accordingly.
5038 * Makefile.in: Update dependencies.
5039 (inner_h_files): Remove params.h.
5041 * gc.c: #include "gc.h"; every module should include its header,
5042 to let the compiler cross-check the declarations against the
5045 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5046 simpos.h: #include "libguile/__scm.h".
5048 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5050 * init.c: Don't forget to #include smob.h and init.h.
5051 * Makefile.in: Dependencies updated.
5053 * smob.h: Use PROTO instead of #if __STDC__.
5055 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5057 * __scm.h: Doc fixes.
5059 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5060 <angles>; this allows `make depends' to work properly.
5062 * libguile.h: #include smob.h and pairs.h before the others; they
5063 define typedefs used by other headers.
5065 C files should #include only the header files they need, not
5066 libguile.h (which #includes all the header files); the pointless
5067 recompilation was wasting my time.
5068 * Makefile.in (all .o dependency lists): Regenerated.
5069 * libguile.h: Don't try to get a definition for size_t here...
5070 * __scm.h: Do it here.
5071 * _scm.h: Since this is the internal libguile header, put things
5072 here that all (or a majority) of the libguile files will want.
5073 Don't #include <libguile.h> here; that generates dependencies on
5074 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5075 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5076 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5172 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
5173 * weaks.c: Get "weaks.h".
5175 * stackchk.h: #include "libguile/debug.h",
5177 * print.h, read.h: #include "options.h", since everyone who uses
5178 either of these files will need that.
5180 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5181 anyone who uses this file will need them to define the smob
5182 printing functions. Also, get markers.h, since people will need
5183 to #define the mark functions.
5185 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5186 * ports.h: ... to here.
5188 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5189 don't rely on archaic C default type rules.
5191 * fports.h: #include "libguile/ports.h", since you need that in
5192 order to parse this.
5194 * genio.h: #include "libguile/print.h", because you need that to
5195 parse this; don't bother #including "ports.h", since print.h gets
5198 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5200 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5201 this; it's now a reference to an element of *scm_root.
5203 * debug.h: Don't #include "options.h"; the compiler won't be able
5204 to find that once the headers are installed; instead, #include
5205 "libguile/options.h".
5206 * gc.h: Same, with marksweep.h.
5207 * mbstrings.h: Same, with symbols.h.
5208 * scmhob.h: Same, with _scm.h.
5209 * smob.h: Same, with params.h.
5211 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5212 C files; there's no need for this, and it forces recompilations
5215 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5217 * error.c (scm_error): declare scm_error_callback.
5219 * error.h: prototype for scm_error_callback.
5221 * __scm.h: define lgh_error.
5222 (SCM_SYSERROR): redefine using lgh_error.
5224 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5226 * error.c (scm_error): new procedure.
5228 * error.h: prototype for scm_error.
5230 * Makefile.in (install): install scmconfig.h from the current
5231 directory, not $(srcdir).
5233 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5235 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5236 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5237 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

5243 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5244 vports.h, weaks.h: #include "libguile/__scm.h", not
5245 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5246 dependencies are within libguile properly.
5248 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5250 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5251 when scmconfig.h doesn't exist.
5253 * load.c (scm_sys_try_load): Correct spelling.
5255 * feature.c (scm_loc_features): Make this static.
5257 * Makefile.in (libpath.h): Omit trailing slash from path. We
5258 shouldn't require it of users, so why put it here?
5260 Move code to initialize and search %load-path from ice-9 to C
5261 code, so we can use the load-path to find the ice-9 boot code;
5262 this makes it easier to run Guile without installing it. See
5263 corresponding changes in guile/Makefile.in.
5264 * feature.c: Move stuff concerned with the load path to load.c.
5265 (scm_compiled_library_path): Deleted.
5266 Don't #include libpath.h here.
5267 * feature.h: Don't mention scm_compiled_library_path.
5268 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5269 <sys/stat.h>, and <unistd.h> (if present).
5270 (R_OK): #define if the system hasn't deigned to.
5271 (scm_loc_load_path): New variable.
5272 (scm_init_load_path, scm_sys_search_load_path,
5273 scm_sys_try_load_path): New functions.
5274 (scm_init_load): Initialize scm_loc_load_path to point to the
5275 value cell of the Scheme %load-path variable.
5276 * load.h: Add declarations for scm_sys_search_load_path,
5277 scm_sys_try_load_path.
5278 * init.c: Call scm_init_load_path.
5279 * Makefile.in (feature.o, load.o): Dependencies updated.
5281 * load.c, load.h: Rewrite using PROTO macro.
5283 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5285 * gc.c (scm_cellp): New function: C predicate to determine if an
5286 SCM value can be regarded as a pointer to a cell on the heap.
5288 * gc.h: Added declaration of scm_cellp.
5290 * gdb_interface.h: New file: The GDB interface header from the GDB
5293 * gdbint.c: New file: GDB interface.
5295 * gdbint.h: New file: GDB interface.
5297 * libguile.h: Added #include <libguile/gdbint.h>.
5299 * init.c (scm_boot_guile): Added scm_init_gdbint.
5301 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5302 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5303 found if object files and source are kept separate).
5305 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5307 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5309 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5311 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5312 TK_SRC_DIR; they're not relevant any more.
5314 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5315 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5317 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5319 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5320 search path, so we can find the <libguile/MUMBLE.h> headers.
5322 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5324 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5325 implicit in the .c.o rule.
5326 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5329 Put the library path in a header file, instead of passing it on
5330 the command line in every compilation.
5331 * Makefile.in (libpath.h): New target.
5332 (feature.o): Depend on libpath.h.
5333 (clean): Delete libpath.h.
5334 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5335 * feature.c: ... #include "libpath.h" here.
5336 * .cvsignore: Ignore libpath.h.
5338 Don't install the unwashed masses of Guile header files in the
5339 main #include path; put most of them in a subdirectory called
5340 'libguile'. This avoids naming conflicts between Guile header
5341 files and system header files (of which there were a few).
5342 * Makefile.in (pkgincludedir): Deleted.
5343 (innerincludedir): New variable; this and $(includedir) are enough.
5344 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5345 (installed_h_files): Divide this up. Now this variable lists
5346 those header files which should go into $(includedir) (i.e. appear
5347 directly in the #include path), and ...
5348 (inner_h_files): ... this new variable says which files appear in
5349 a subdirectory, and are referred to as <libguile/mumble.h>.
5350 (h_files): List them both.
5351 (install): Create innerincludedir, not pkgincludedir. Put
5352 the installed_h_files and inner_h_files in their proper places.
5353 (uninstall): Corresponding changes.
5354 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5355 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5356 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5357 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5358 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5359 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5360 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5361 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5362 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5363 vports.h, weaks.h: Find __scm.h in its new location.
5364 * __scm.h: Find scmconfig.h and tags.h in their new locations
5365 (they're both "inner" files).
5367 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5369 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5371 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5373 * posix.c: Doc fixes.
5375 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5377 * socket.c: Don't include a prototype for inet_aton; just use a
5378 K&R style declaration, to avoid warnings but minimize the chance
5379 of conflicts with the system.
5381 On NextStep, <utime.h> doesn't define struct utime, unless we
5382 #define _POSIX_SOURCE before #including it.
5383 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5384 * acconfig.h: New comment text for above CPP symbol.
5385 * configure.in: Call it.
5386 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5388 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5390 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5391 testing for __EMX__.
5393 * posix.c: #include <libc.h>, if it exists.
5395 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5396 don't even know if the latter exists.
5398 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5399 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5400 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5402 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5404 (scm_init_posix): Use them when initializing the Scheme constants
5407 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5409 * Makefile.in (libdir, includedir, bindir): Use the
5410 autoconf-supplied values, instead of deriving them ourselves.
5411 (pkgincludedir, datadir, pkgdatadir): New variables.
5412 (install, uninstall): Put the header files in a special
5413 subdirectory, not in the main search path.
5415 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5416 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5418 * Makefile.in (IMPLPATH): Deleted; never used.
5420 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5421 on the Tcl/Tk source any more.
5422 (INCLUDE_CFLAGS): Remove references to the above.
5424 * Makefile.in (version.o): Corrected dependencies.
5426 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5428 * libguile.h: #include "version.h"
5430 * init.c (scm_boot_guile): Call scm_init_version.
5431 * gscm.c (gscm_run_scm): Call scm_init_version.
5433 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5434 GUILE_VERSION): AC_DEFINE these.
5435 (acconfig.h): #undef the above symbols.
5437 * Makefile.in (libobjs): Add version.o.
5438 (installed_h_files): Add version.h.
5439 (c_files): Add version.c.
5440 (gen_c_files): Add version.x.
5441 (version.o): New rule.
5442 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5443 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
5444 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
5445 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
5446 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
5447 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
5448 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
5449 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
5450 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
5451 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5452 weaks.o): Add version.h to dependency lists.
5453 (markers.o): Remove duplicate rule.
5455 * version.h: New file.
5457 * version.c: New file.
5459 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5461 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5462 array; use it appropriately. Since GCC is quite happy to
5463 subscript functions, it never warned us about this; we should use
5464 -Wpointer-arith in the future. I guess we never tested
5467 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5469 * socket.c: Doc and copyright fixes.
5471 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5473 * debug.c: Fixed and improved gdb support.
5475 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5477 * socket.c: Added declaration of inet_aton to avoid compiler
5478 warning. (Hope this solution is correct.)
5480 * stime.c: Added declaration of ftime. (This is missing in
5483 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5485 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5487 * Makefile.in (c_files): add strerror.c.
5489 * strerror.c: new file from Emacs' sysdep.c.
5490 maybe configure should also check for sys_errlist.
5492 * configure.in (AC_REPLACE_FUNCS): add strerror.
5494 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5496 * debug.c (scm_init_debug): Added initialization for
5497 scm_evaluator_traps.
5499 * debug.h, debug.c: Various name changes.
5500 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5501 "debug-options-interface". See commentary in options.c.
5503 * options.h, options.c: Options now have documentation strings.
5504 Also added a long explanatory commentary.
5506 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5509 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5510 last_debug_info_frame is now updated in all cases.
5512 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5515 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5517 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5518 Added option STACK_CHECKING.
5520 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5522 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5524 * __scm.h: Removed symbols for debugging support.
5526 * acconfig.h: Added symbols for debugging support.
5528 * configure.in: Added user option for debugging support.
5529 --enable-debug will include the debugging code into libguile.a.
5531 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5532 scm_relocate_chunk_to_heap.
5534 * debug.c: New file: low-level debugging support. It also
5535 includes support for debugging with gdb. (The extensions to gdb
5536 are written by Per Bothner at Cygnus.)
5538 * debug.h: New file: low-level debugging support.
5540 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5541 argument pairs. Extensive modifications to the debugging
5542 evaluator. Added "SECTION:" commentaries to clarify what happens
5543 when, during double compilation. Renamed EVALIMP --> EVALIM.
5544 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5545 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5546 the beginning of the file. New procedure: scm_unmemocopy.
5547 Added some global state variables needed by the debugging
5548 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5549 check_entry, check_apply, check_exit, debug_options and
5550 evaluator_traps. New acro: undefine.
5552 * eval.h: Renamed EVAL --> XEVAL.
5554 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5555 --> scm_make_weak_key_hash_table.
5557 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5558 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5560 * libguile.h: Conditionally include debug.h
5562 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5563 scm_object_properties shouldn't return handle. `handle' now gets
5564 initialized in scm_set_object_properties_x. scm_object_properties
5565 doesn't any longer create an entry in scm_object_whash.
5567 * options.c: New file: handling of run time options.
5569 * options.h: New file: handling of run time options.
5571 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5573 * print.c: New procedure: scm_print_options
5575 * print.h: Defines for print options.
5577 * read.c: New procedure: scm_read_options
5579 * read.h: Defines for reader options.
5581 * root.h: Added scm_source_whash among scm_sys_protects.
5583 * srcprop.c: New file: source properties.
5585 * srcprop.h: New file: source properties.
5587 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5588 (Bug found by A. Green.)
5590 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5592 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5594 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5596 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5598 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5599 and should be called by the final client.
5601 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5603 * gc.h: Use the PROTO macro when declaring functions.
5604 * gc.c: Use the PROTO macro when declaring static functions.
5605 Remove the CPP hair around function definitions.
5607 * gc.c (scm_init_storage): Initialize scm_asyncs.
5609 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5610 preprocessor symbol; "__scm.h" is where it might get #defined.
5611 * __scm.h: Similar: #include <scmconfig.h> before testing
5614 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5616 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5618 * init.c (scm_boot_guile): Add init_func argument; call
5619 (*init_func) instead of calling scm_appinit; it's ucky to
5620 hard-code names for the user's procedures.
5621 * init.h (scm_boot_guile): Adjust declaration.
5623 * __scm.h (PROTO): New macro, for declaring functions with
5626 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5627 eliminate all the __STDC__ conditionals.
5628 (scm_boot_guile): Add declaration.
5629 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5630 Remove __STDC__ conditionals around function definitions; the
5631 declarations in init.h will provide the same information, more
5634 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5635 complain about it in the error message; the error message is
5636 adequate without that note, and there's nothing the user can do
5639 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5641 * Makefile.in (ancillary): Drop def.sed.
5643 * posix.c (scm_init_posix): Use numeric values, rather than
5644 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5645 F_OK. The symbols aren't available on some systems, and I'm
5646 pretty sure their values are fixed by common widespread practice.
5647 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5649 More functions unavailable on some systems.
5650 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5651 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5653 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5654 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5655 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5656 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5657 stub that signals an error as the #else.
5659 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
5661 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
5663 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
5665 * unif.c: include ramap.h.
5667 * read.c (endif): case_insensative_p renamed case_insensitive_p.
5669 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
5671 * ports.c: include sys/ioctl.h.
5673 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
5675 * configure.in: check for sys/ioctl.h.
5677 * ports.c: include <malloc.h> not "malloc.h".
5679 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5681 * fports.c: remove ttyname and tmpnam declarations.
5683 * posix.c: fewer ttyname declarations.
5685 * fports.c: include <string.h> not "string.h".
5687 * init.c, ioext.c: include string.h and unistd.h.
5689 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5691 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
5692 genio.c, simpos.c, vports.c: include string.h.
5694 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
5696 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
5698 (scm_addr_buffer_size): change type from scm_sizet to int.
5699 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
5700 from scm_sizet to int.
5702 * error.c: include unistd.h.
5704 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
5707 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
5709 * __scm.hd, def.sed: deleted.
5711 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
5713 Changes for NeXT, suggested by Robert Brown.
5714 * configure.in: Call AC_TYPE_MODE_T.
5715 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
5716 NeXT. Put header file list in alphabetical order.
5717 * configure, scmconfig.h.in: Regenerated.
5718 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
5720 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
5723 * acconfig.h: New file, providing documentation for the CPP
5724 symbols defined in configure.in
5725 * acconfig-1.5.h: Removed; superceded by the above.
5727 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
5729 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
5731 * fports.c (scm_open_file): don't return #f, throw error.
5733 * ioext.c (fileno): renamed from %fileno.
5734 (soft-fileno): deleted.
5736 * ports.c (scm_port_revealed): don't need to check for -1 from
5738 (scm_set_port_revealed_x): return unspecified, not #f.
5740 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
5742 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
5744 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
5746 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
5748 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5750 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5751 This is necessary on Ultrix, and doesn't hurt portability.
5753 * Makefile.in (dist-dir): New target, implementing a new dist system.
5754 (installed_h_files): Put in alphabetical order.
5755 Remove duplicate entries for markers.h and unif.h.
5756 (c_files): Remove duplicate entries for markers.c.
5757 (ancillary): Renamed from anillery; all uses changed. Remove
5758 PLUGIN; it's a directory, and needs special treatment in dist-dir.
5759 Remove all the ../doc/* files; doc/Makefile.in handles that.
5761 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5763 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5764 every if must have an else, or else the whole command has a

6024 initialization to fix a race condition.
6026 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
