1 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
3 * scmconfig.h.in: Regenerated.
5 * libguile.h: Don't omit the dynamic linking functions. (Thanks
8 * genio.c (scm_do_read_line): Count lines correctly when the file
9 doesn't end in a newline.
11 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
13 * genio.c (scm_do_read_line): Maintain the line count correctly.
14 (Thanks to Harvey J. Stein and Greg Harvey.)
16 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
19 * numbers.c (big2str): Protect t from garbage collection until
20 we're done. (Thanks to Gary Houston.)
22 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
24 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
26 * Makefile.in: Regenerated.
28 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
29 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
32 Do magic to mix reads and writes on stdio FILE-based ports.
33 (Thanks to Christian Lynbech.)
34 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
36 (pre_read, pre_write): New functions.
37 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
38 local_fputs): Call them.
39 (local_fflush): Mark the port as ready for reading and writing.
40 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
41 flags on new port objects. This might not be accurate --- who
42 knows what state the FILE * is in when we get it --- but it won't
43 do extraneous calls to fflush or fseek, so it's no worse than the
44 behavior before this change.
45 * ports.h: Add comment.
47 Centralize the creation of port objects based on stdio FILE * in
48 fports.c; don't just throw them together anywhere.
49 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
50 what the rest of Guile wants. Don't set the revealed count;
51 that's only appropriate for stdin, stdout, stderr.
52 (scm_standard_stream_to_port): This function does set the revealed
54 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
55 not scm_stdio_to_port.
56 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
57 * fports.c (scm_open_file): Same.
58 * posix.c (scm_pipe): Same.
59 * socket.c (scm_sock_fd_to_port): Same.
60 * ioext.c (scm_fdopen): Same.
61 (scm_freopen): Moved from here to...
62 * fports.c (scm_freopen): ... here. This is really something that
63 munges the internals of an fport, so it should go here.
64 * fports.h (scm_stdio_to_port): Adjust prototype.
65 (scm_standard_stream_to_port, scm_freopen): New protoypes.
66 * ioext.h (scm_freopen): Prototype removed.
68 * filesys.c (set_element, get_element): This can work on both pipe
69 and file ports, so use SCM_FPORTP to typecheck, instead of testing
72 * scmconfig.h.in: Regenerated.
74 Change the definition of the functions in scm_ptobfuns so that
75 they get passed the port object, not the port's stream.
76 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
77 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
78 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
79 Pass the port itself to the scm_ptobs function.
80 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
81 scm_generic_fgets): Same.
82 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
83 getc_void_port, fgets_void_port, close_void_port): Just change the
84 argument names; these functions don't really do anything.
85 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
86 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
87 port as an argument, and use SCM_STREAM to get the stdio FILE *.
88 Also, use prototyped definitions, and get rid of the extra
90 (scm_fptob, scm_pipob): We don't need casts here any more.
91 * strports.c (prinstpt): Use prototype declarations.
92 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
93 and use SCM_STREAM to get the string info. Also, use prototyped
94 definitions, and get rid of the extra declarations.
95 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
98 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
99 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
101 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
102 scm_fgets, for consistency.
103 (scm_fptop, scm_pipob): References updated.
105 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
107 Include the source location in error messages for scripts.
108 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
109 stack is still there when we catch the error.
110 * throw.c (handler_message): If we are handling an error with a
111 message, then put together the proper arguments and call
112 scm_display_error, instead of scm_display_error_message. That
113 displays source location, if it can find it.
115 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
117 * gc.c (scm_unprotect_object): Change this so that calls to
118 scm_protect_object and scm_unprotect_object nest properly.
119 (scm_protect_object): Doc fixes.
121 * strings.c (scm_string_set_x): Require the argument to be a
122 writable string, not a substring or a symbol.
123 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
124 (Thanks to John Redford and Charbel Jacquin.)
126 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
128 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
130 * eval.c (safe_setjmp): Remove this misunderstanding.
131 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
134 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
136 * libguile.h: Mark these as C declarations, for compilation by C++
139 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
140 __cplusplus clause. I seriously doubt this ever worked the way
141 the author seems to have intended.
143 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
145 Utterly needless cleanups to hopelessly messy code.
146 * ports.c: Doc fixes.
147 (scm_fflush): Moved to ...
148 * genio.c (scm_fflush): ... here, amongst all the other port
149 method invocation functions.
150 * genio.h, ports.h: The prototype moves too.
152 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
154 * backtrace.c (display_error_body): The current frame does not
155 always have a parent frame; consider a function called directly
156 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
159 * alloca.c (alloca): Undo yesterday's changes, and simply call
160 malloc directly for storage, and abort if we don't get what we
161 want. The situation is much simpler --- just call malloc. Emacs
162 has bizarre/evil requirements (signal handlers might malloc unless
163 you set this global flag, so you have to set the flag around all
164 calls to malloc) which we are certainly not going to conform to,
165 so we can do the simple and obvious thing.
167 * coop.c (coop_condition_variable_wait): Make this function
168 static. It's only useful internally --- you should never just
169 wait on a condition variable.
170 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
172 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
174 * unif.c (scm_array_set_x): Accept any kind of number as an
175 element for a uniform vector of doubles. This is more consistent
176 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
178 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
179 works; I can't conveniently test it myself. (Thanks to Dvid
180 Tillman for the bug report.)
184 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
185 from here, not from scm_compile_shell_switches (which is a pretty
186 dumb place to do it).
187 (scm_load_startup_files): New function.
188 (scm_ice_9_already_loaded): Variable moved to here from script.c.
189 * script.c (scm_compile_shell_switches): Don't load the startup
191 (scm_ice_9_already_loaded): Variable moved.
192 * init.c (scm_load_startup_files): Prototype for new function.
193 * gh_init.c (gh_enter): Doc fix.
195 1998-10-03 <jimb@savonarola.red-bean.com>
197 Some anti-warning changes from Greg Harvey.
198 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
199 warnings when it doesn't understand our NORETURN declarations in
201 * posix.c (scm_mknod): Similar.
203 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
205 * posix.c (scm_getpwuid): If we can't find an entry, return our
206 own message, instead of using scm_syserror --- the getpwMUMBLE
207 functions don't set `errno' to anything interesting.
209 1998-10-03 <jimb@savonarola.red-bean.com>
211 Get rid of warnings from the cooperative threading system.
212 * threads.h (scm_single_thread_p, scm_yield,
213 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
214 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
215 scm_wait_condition_variable, scm_signal_condition_variable): Add
216 prototypes for these Scheme-visible functions.
217 * coop-defs.h (coop_next_runnable_thread,
218 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
219 Prototypes for these here, even though they're from iselect.c.
220 (coop_condition_variable_wait, coop_join): Add prototypes.
221 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
222 scm_threads_free_condvar): Make these smob functions static.
223 * coop-threads.h (coop_init): Give this a real prototype.
224 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
225 (coop_next_runnable_thread): No need to provide prototype; it's in
228 * scmconfig.h.in: .detarenegeR
230 * iselect.c, threads.c: Doc fixes.
232 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
234 * Makefile.in: Regenerated with a patched automake, to get
235 dependency generation right when using EGCS.
237 * inet_aton.c (inet_aton): Add prototype, to remove compiler
238 warning. (Thanks to Robert Pluim.)
240 * inet_aton.c (inet_aton): Reassure the compiler that the
241 arguments to the <ctype.h> macros are all unsigned characters, not
244 1998-10-03 <jimb@savonarola.red-bean.com>
246 Getting rid of more warnings...
247 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
248 today's change to ../configure.in.
249 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
250 * scmconfig.h.in: Regenertaded.de.,.__
251 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
252 (scm_localtime, scm_mktime): Use a const char * to manipulate the
255 * readline.c: Doc fix.
256 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
257 * readline.h (scm_filename_completion_function): Add prototype.
258 (scm_init_readline): Make this into a prototype.
260 * readline.c (scm_filename_completion_function): Use SCM_PROC to
261 declare this, instead of calling scm_make_subr manually.
263 1998-10-02 <jimb@savonarola.red-bean.com>
265 * readline.h (scm_init_readline): Add prototype for this.
266 (scm_init_readline): Make this a real prototype.
268 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
270 Warning fixes from Maciej Stachowiak:
271 * backtrace.h (scm_display_application, scm_backtrace): Add
273 * debug.c (scm_m_start_stack): Make this function static.
274 * fluids.h (scm_fluid_p): Add prototype.
275 * procprop.c (scm_i_procedure_arity): Make this function static.
276 * regex-posix.c (scm_regexp_error_msg): Make this function static.
277 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
278 * root.h (scm_dynamic_root): Add external prototype.
279 * scmsigs.h (scm_usleep): Add external prototype.
280 * script.h (scm_init_script): Use prototype, not K&R decl.
281 * stacks.h (scm_stack_id): Add external prototype.
282 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
284 1998-09-30 Mark Galassi <rosalia@cygnus.com>
286 * gh.h: took out the definitions of vset and vref, since they are
287 replaced by the proper vector routines that correspond to the R4RS
290 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
292 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
293 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
294 third argument, a C expression that should result in a SCM value,
295 which is used to initialize the variable. Reimplemented
296 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
299 * version.h (scm_libguile_config_stamp): Add prototype.
300 (From Maciej Stachowiak.)
302 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
304 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
305 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
307 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
309 * print.c (scm_iprin1): Rather than having one i, and using it in
310 several places, declare a fresh i local to each block where it is
311 used, and give it a signedness appropriate to its use in each case.
314 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
317 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
318 signed/unsigned clashes.
320 * posix.h (scm_tmpnam): Added prototype.
322 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
323 scm_make_subclass_object): Add external prototypes.
325 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
326 comparison is okay here.
328 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
330 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
331 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
333 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
336 * load.c (swap_port): Make this function static.
338 * load.c (scm_search_path): Make max_path_len and max_ext_len
339 unsigned, since they're compared against string sizes.
341 * load.c (init_build_info): Make i unsigned.
343 * ioext.h (scm_read_line): Add prototype.
345 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
346 scm_hash_fn_remove_x): Make hash bucket index local variable k
347 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
348 accurately as possible.
350 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
351 comparisons, and range checking to make sure those casts are
354 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
355 signed/unsigned comparisons.
357 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
358 avoid signed/unsigned comparisons.
359 * smob.h (scm_numsmob): Change extern declaration to match.
361 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
362 avoid signed/unsigned comparisons.
363 * ports.h (scm_numptob): Change extern declaration to match.
364 (scm_current_load_port, scm_set_port_line_x,
365 scm_set_port_column_x): New prototypes.
367 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
368 test code, and it causes warnings.
370 * gh.h (gh_int2scmb, gh_uniform_vector_length,
371 gh_uniform_vector_ref): Added prototypes.
373 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
374 debugging support unconditionally. That's backtrace.c, stack.c,
375 debug.c, and srcprop.c.
376 (EXTRA_libguile_la_SOURCES): Omit those from here.
377 * Makefile.in: Regenerated.
379 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
381 * options.c (scm_options): Bugfix: Allow empty list of options!
383 * debug.c, debug.h (scm_single_step): Removed.
384 (scm_with_traps): New procedure. This procedure could easily be
385 written in Scheme but needs to be highly optimized.
387 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
389 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
390 Check SCM_TRAPS_P before trapping.
392 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
394 Changes to avoid signed/unsigned comparison warnings.
395 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
396 (scm_gc_sweep): Make n and j local to the blocks they're used in,
397 so they can have appropriate types for each application. Make i
398 signed. Use initializers in some spots. I'll probably pay for
400 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
401 (scm_must_realloc): Make nm unsigned.
402 (init_heap_seg): Make new_seg_index and n_new_objects signed.
403 (scm_init_storage): Use prototype-style definition, and make the
405 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
406 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
408 * filesys.c (scm_readlink): Make local vars rv and size ints, to
409 avoid signed/unsigned comparison warnings, and because the return
410 value of readlink may be -1. Don't bother casting the third
411 argument to readlink.
413 * filesys.c (scm_dirname, scm_basename): Move these to their own
414 page, at the end of the file.
415 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
417 * eval.h (scm_eval_options_interface): Add external prototype for this.
418 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
420 * eval.c (scm_lookupcar1): Make this static.
422 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
423 Make these prototype declarations, not K&R-style.
425 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
426 unsigned comparison warning.
428 * appinit.c: File removed. It had a single function in it, empty,
429 whose reason for existence is explained in no documentation or
430 comment. I think it's there as a default for some Tcl-style
431 initialization, but Tcl abandoned that approach a while ago.
432 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
433 (BUILT_SOURCES): Remove appinit.x.
434 * Makefile.in: Regenerated.
436 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
438 * Makefile.in: Regenerated using the last public version of
439 automake, not the hacked Cygnus version.
441 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
443 Remove Totoro kludge.
444 * Makefile.in, scmconfig.h.in: Regenerated.
445 * init.c, readline.c: Don't check if TOTORO is #defined.
447 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
449 * Makefile.am: Adjust for new thread configuration system.
450 (INCLUDES): Include the value of THREAD_CPPFLAGS.
451 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
453 (THREAD_LIBS): Definition deleted; automake will generate such
454 things automatically.
455 * Makefile.in: Regenerated.
457 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
459 Simplify smob and port marking; set the mark bit in the generic
460 marking code, and make marker routines only responsible for
461 turning up outgoing pointers.
462 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
463 before calling the marking function. Don't call the marking
464 function if it's zero.
465 * markers.c (scm_mark0): Just return #f. This function isn't
466 necessary at all now, but it's harmless to call it. We'll leave
467 it in so other folks' code doesn't croak at link time.
468 (scm_markcdr): Don't call SCM_SETGC8MARK.
469 * async.c (mark_async): Don't call SCM_SETGC8MARK.
470 * dynl.c (mark_dynl_obj): Same.
471 * root.c (mark_root): Same.
472 * srcprop.c (marksrcprops): Same.
473 * unif.c (markra): Same.
474 * variable.c (scm_markvar): Same.
475 * ports.c (scm_markstream): Same.
476 (void_port_ptob): Specify zero for our marking function.
477 * debug.c (debugobjsmob): Same.
478 * dynwind.c (guardsmob): Same.
479 * filesys.c (dir_smob): Same.
480 * fluids.c (fluid_smob): Same.
481 * fports.c (scm_fptob, scm_pipob): Same.
482 * mallocs.c (mallocsmob): Same.
483 * regex-posix.c (regex_t_smob): Same.
484 * smob.c (freecell, flob, bigob): Same.
485 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
486 * throw.c (jbsmob, lazy_catch_funs): Same.
488 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
490 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
491 scm_copy_tree on code in order not to let memoized code to leak
492 out. Thus, scm_copy_tree needs to copy vectors as well since
493 quasiquote can introduce evaluated code also inside vector
496 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
498 * eval.c (scm_copy_tree): Removed ability to copy vectors.
500 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
501 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
504 * unif.c: Say that ivect and uvect are of type signed and unsigned
505 long instead of int in commentary so that it correctly describes
508 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
510 * stime.c: Removed declaration of strptime. (It should be
511 declared by the system headers. If it turns out that some systems
512 don't, we'll handle that then.) (Thanks to Greg Troxel.)
514 * stime.h: Renamed TIMEH --> STIMEH
516 * backtrace.c (scm_display_error, scm_display_backtrace): In order
517 to increase portability, don't use structure assignment.
518 (Thanks to Nicolas Neuss.)
520 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
522 (finalize_fd_sets): Added empty statement after last case label.
523 (Thanks to Nicolas Neuss.)
525 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
528 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
530 * init.c, readline.c: OK, I won't have these readline.x bug
531 reports anymore. We've had them since April. The current reason
532 is a completely unintelligible failure of totoro.red-bean.com to
533 do the test for rl_getc_function in libreadline correctly. This
534 kludge overrides the test if we're on totoro so that the snapshot
535 generation process can work.
537 * readline.c: Define a strdup replacement if not existent on system.
539 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
541 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
542 This change makes scm_make_vector R5RS compatible. We cannot keep
543 the third argument since people want to be able to deduce the form
544 of the C function call only by looking at R5RS. (At the same time
545 we have removed some unnecessary complexity!)
547 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
548 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
549 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
550 argument in call to scm_make_vector.
552 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
554 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
555 This macro is useful in applications.
557 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
559 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
560 (scm_parse_path, scm_search_path): New Scheme level procedures.
562 * load.h (scm_internal_parse_path, scm_parse_path,
563 scm_search_path): Declared.
565 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
567 * filesys.c (dirname, basename): New procedures.
569 * init.c (scm_boot_guile_1): Removed condition around
572 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
573 new data type (guards) for representation of C level guards and
574 data on the wind chain.
575 (scm_internal_dynamic_wind): New function.
577 * dynwind.h: Declare scm_internal_dynamic_wind.
579 * root.h (scm_root_state): Added scm_cur_loadp.
581 * root.c (mark_root): Added comment about cur_loadp.
583 * load.c: #include "dynwind.h";
584 (scm_primitive_load): Use scm_inner_dynamic_wind to update
587 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
589 * ports.c (current-load-port): New procedure.
591 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
593 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
594 not a tty, return #f.
596 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
597 to Julian Satchell and Roland Kaufmann.)
599 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
600 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
602 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
604 * debug.h, debug.c (scm_start_stack): New function. Implements
605 the guts of old scm_m_start_stack.
607 * debug.c (scm_m_start_stack): Use scm_start_stack.
609 * init.c (scm_start_stack, scm_restart_stack): Renamed to
610 start_stack and restart_stack. (These have static scope.)
612 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
614 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
615 readline functions to come in release 2.3. (Thanks to Chet
617 (handle_errors): Use the above functions.
619 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
621 * readline.c: Improvements for readline support: Handle errors
622 better; Implement before-read-hook.
624 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
626 * init.c (scm_boot_guile_1), readline.c: Test for
627 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
628 assure that we have version >= 2.1.)
630 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
632 * readline.c (scm_readline): Defer interrupts while we're calling
635 * readline.c (scm_add_history): Bugfix: Do strdup before giving
636 away the string to add_history.
637 (completion_function): Do completion for readline. (Thanks to
639 (scm_filename_completion_function): New procedure: Filename
641 (current_input_getc): New function. Use this one instead of
642 standard getc from readline.
644 * throw.c, throw.h (scm_handle_by_throw): New function: This
645 handler throws errors to next handler on the dynwind chain.
647 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
649 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
652 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
654 * procprop.c (scm_i_procedure_arity): New function. Returns arity
656 (scm_procedure_properties): Modified to return arity together with
658 (scm_procedure_property): Added the read-only property `arity'.
659 (scm_set_procedure_property_x): It is an error to set the `arity'
662 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
663 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
665 * procprop.h (scm_sym_arity): New symbol.
667 * objects.c (scm_set_object_procedure_x): New procedure: Use this
668 to set the dispatch procedure of an operator or entity object.
670 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
671 Made procedure slots read-only.
673 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
674 scm_tcs_cons_gloc case in zero args switch; Fixed args
675 construction for operators in scm_tcs_cons_gloc case in two args
678 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
680 * fluids.c: Removed use of assert.h (in order to avoid
683 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
685 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
687 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
688 change makes the evaluator safer at the cost of evaluation speed.
689 It handles the case when the user has added a non-immediate
690 improper end of the application form, e.g., `(+ 0 . x)'.
691 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
692 minimize the extra cost as much as possible. The new code is
693 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
694 problem with structs planted directly in the code (e.g. by a
695 macro). This no longer causes segmentation fault. (Thanks to
698 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
699 arg `proc' in order to be able to throw errors; New argument
702 * Removed extra #include "debug.h"
704 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
706 * scmsigs.c: Declare usleep as returning void on some systems.
707 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
710 * coop.c (usleep): Return void on some systems.
712 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
714 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
716 * coop.c: Changed return type of usleep to int.
718 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
719 isn't found in the OS.
721 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
722 isn't enabled. (Thought that I had made this change ages ago...)
724 * iselect.c: Declare bzero if not defined by OS.
726 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
728 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
729 condition. (Thanks to John Tobey.)
731 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
732 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
735 * __scm.h: Start the long-term project of moving to POSIX threads.
736 Phase 1: Classification of all critical sections.
737 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
738 for A sections. (See comments in __scm.h for details.)
740 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
741 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
743 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
745 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
746 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
747 (libpath.h, versiondat.h): Replaced dependency on Makefile with
748 dependencies on $(srcdir)/Makefile.in
749 $(top_builddir)/config.status in order to avoid circularity.
751 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
752 from argc if argc was 0 initially.
754 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
755 in generation of libpath.h.
757 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
759 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
760 libguile from 2 to 3.
762 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
764 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
766 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
768 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
769 scm_set_port_column_x, scm_port_filename,
770 scm_set_port_filename_x): Removed optional arguments. Added
771 proper argument checking.
773 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
774 stack size in machine words.
776 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
777 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
778 to Ole Myren Röhne.)
780 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
782 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
783 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
785 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
788 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
789 procedure apply: Copy argument lists before pushing them unto the
790 environment so that the environment won't get mutated due to
791 manipulation of procedure arguments. This should perhaps be
792 regarded as a temporary solution until someone finds a more
793 efficient one. (Thanks to Maciej Stachowiak.)
795 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
797 * script.c (scm_compile_shell_switches): Use "guile" as default
798 zero arg if argc is NULL.
800 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
802 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
803 is zero. (Thanks to Dirk Herrmann.)
805 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
807 * ports.c (scm_add_to_port_table): First line is now line 0
808 (was 1). (Interface changed according to suggestion by Per
811 * backtrace.c (display_header): Add 1 to line and column numbers
812 when presenting them to the user.
814 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
815 from debug.c --> eval.c
817 * eval.h, eval.c (scm_eval_options_interface): New options
819 (SCM_EVAL_STACK): New option: Size of newly created stacks,
820 i.e. stacks for new threads.
822 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
824 * eval.c (unsafe_setjmp): Removed with #if 0.
826 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
829 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
830 to avoid compiler warnings.
832 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
834 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
836 * throw.c (handler_message): Print message on current error port
837 instead of default error port. (Thanks to Maciej Stachowiak.)
839 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
841 * ports.c (scm_add_to_port_table): allocate in units of
842 struct scm_port_table *, not struct scm_port_table.
843 * posix.c (scm_close_pipe): remove the port from the port table
845 Thanks to Rob Engle for both fixes.
847 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
849 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
850 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
852 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
854 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
856 * backtrace.c (display_error_body, display_backtrace_body),
857 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
858 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
859 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
860 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
863 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
864 don't receive the jmpbuf arg anylonger.
865 (scm_catch): Don't accept a #f tag.
866 (scm_throw): Check that key is a symbol.
867 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
869 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
871 * async.c (async_pending): Removed declaration.
873 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
875 * dynwind.c (scm_wind_chain): New debug function.
877 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
878 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
879 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
880 extra layer of functions around the body and handler of a thread.
881 This extra layer makes sure that the handler is called in the
882 dynamic context of the surround (= empty dynwind list), but under
883 the *dynamic root* of the body. We can not use the dynamic root
884 of the surround since that root belongs to another thread => stack
885 is not handled correctly. It may seem ugly to use this extra
886 layer, but the extra cost in terms of execution time is really
887 negligible compared to the total amount of time required to create
888 a thread, and it would reduce maintainability to duplicate the
889 crucial and complicated steps performed by cwdr.
891 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
892 (SCM_ALLOW_INTS): Added thread switching code before interrupts
893 get re-enabled. The important effect of this is that interrupts
894 are blocked during thread switching so that thread data structures
895 don't risk getting messed up by an unfortunate signal.
896 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
897 seems to do more aggressive optimization which actually move
898 instructions around in these macros in a fatal way. Therefore:
899 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
900 just superstitious...)
901 (SCM_TICK): Maybe do a context switch and take care of asyncs.
902 This macro should be used instead of SCM_ASYNC_TICK since the
903 latter doesn't do context switches any more.
905 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
906 instead of SCM_ASYNC_TICK.
908 * coop.c, iselect.c: Since thread switches are now performed with
909 interrupts masked, we can't use the old mechanism of delivering
910 signals immediately when they arrive. Signals must instead be
911 delivered when the asyncs run *after* the end of the critical
912 section in scm_internal_select. But this also means after context
913 switch so that the signal will be delivered to a different thread.
914 To avoid this, I have changed the protocol of
915 coop_wait_for_runnable_thread and friends so that they are allowed
916 to return the original thread. So, if a signal arrives during
917 scm_internal_select, we won't any longer be forced do a context
918 switch, but can remain in the same thread and deliver the signal
921 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
922 scm_asyncs_pending and made it global.
924 * iselect.c: Small fixes.
926 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
927 coop_condition_variable_init, coop_condition_variable_wait,
928 coop_condition_variable_signal): Changed return type from `void'
929 to `int'. This is to adhere closer to the pthreads interface.
930 This, in turn, is part of an attempt to provide C versions of the
931 mutex and condition variable primitives which can be part of a
932 frontend to COOP or pthreads.
934 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
935 coop_condition_variable_destroy): New functions.
937 * coop-threads.c (scm_wait_condition_variable): Use
938 coop_condition_variable_wait_mutex.
940 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
941 Definitions moved to coop-defs.h.
943 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
944 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
945 scm_cond_destroy): New C interface to mutecis and cond vars.
947 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
949 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
951 * iselect.c: Now several threads can wait on the same file
952 descriptor. The behaviour is compatible with OS select: All
953 threads waiting for the fd return with the same status.
955 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
957 * coop-threads.c, threads.h (scm_spawn_thread): New function.
958 Can spawn a thread from application C code.
960 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
962 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
963 gh_doubles2scm): New functions.
965 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
967 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
968 commented-out version of gh_eval_str()
970 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
972 * socket.c (scm_bind): free soka after use.
974 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
976 * stime.c (tzvar): new variable.
977 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
978 avoid memory leaks when allocating.
980 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
982 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
985 * gc.c, tags.h: Doc fixes.
987 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
989 * eval.c (macro-eval!): Removed. This function was a design bug.
990 It allowed memoized code to leak out to the scheme level. Most
991 things that you could do with `macro-eval!' can be done with
994 1997-12-20 Tim Pierce <twp@skepsis.com>
996 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
997 scm_fgets now depends on ftell(3) to know how many bytes were
1000 1997-12-15 Tim Pierce <twp@skepsis.com>
1002 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
1003 dealing with strings.
1005 1997-12-13 Tim Pierce <twp@skepsis.com>
1007 Make %read-line more suitable for implementing read-line efficiently.
1008 * ioext.c (scm_read_line): Strip the terminating newline from a
1009 string, and return a cons of the string and its terminator.
1011 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
1012 of the string that is read is stored in this memory location.
1013 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
1014 * genio.c, genio.h (scm_do_read_line): Update caller.
1015 * ports.h (scm_ptobfuns): Update typedef.
1016 * fports.c (scm_fptob, scm_pipob): Update struct.
1018 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1020 * filesys.c (set_element): Return file descriptor.
1021 (fill_select_type): Return the highest file descriptor.
1022 (scm_select): Tell select about the highest file descriptor. On
1023 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
1024 Therefore the extra overhead for calculating the maximum fd seems
1025 to be more than compensated. Is this correct? In any case,
1026 scm_internal_select will be much faster with this info.
1027 (scm_select, fill_select_type, set_element): Don't accept any kind
1028 of object in the file descriptor list or vector.
1030 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1032 * iselect.c (finalize_fd_sets): Bugfix.
1034 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1036 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1037 when using scm_internal_select (since we might switch to another
1040 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1042 * simpos.c (scm_system): always define: use sysmissing if not
1043 available. Check for HAVE_SYSTEM instead of _Windows (does
1044 Windows lack system or does it have an unusable one?).
1045 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1046 Let the argument be optional: if not supplied, call system(NULL).
1048 * ports.c (scm_close_port): relax the type check from OPPORTP to
1049 PORTP; closing a closed port is allowed.
1051 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1053 * fports.c (scm_fgets): Return if the last char in a chunk is
1054 newline. When fgets returns a string whose length is `size-1', it
1055 is ambiguous whether a whole line was retrieved, so we must check
1056 explicitly whether a line terminator is present.
1058 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1060 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
1061 before taking the CDR. (Thanks to Harald Meland.)
1063 * filesys.c (scm_stat): Slightly optimized.
1065 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
1067 * ports.c (scm_close_port): Make sure the port is open before
1070 * guile-snarf.in: Pass args through to gcc in a way that preserves

1075 * stacks.c (scm_frame_procedure): Reverse the logic in the return
1076 statement. (Thanks to Doug Evans for pointing this out.)
1078 1997-12-01 Tim Pierce <twp@skepsis.com>
1080 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
1082 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
1084 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
1085 errno macro expansion of this field name. (errno is a C
1086 preprocessor macro on some systems.)

1103 * root.h (scm_root_state): Removed the_last_stack_var.
1105 * throw.c: Added #include "fluids.h"

1108 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
1109 --> the_last_stack_fluid.
1111 * backtrace.c: Added #include "fluids.h"
1112 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
1113 (scm_backtrace): `the-last-stack' is now a fluid.
1115 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
1116 after scm_init_fluids.
1118 1997-11-28 Tim Pierce <twp@skepsis.com>
1120 * iselect.c: #ifdef USE_THREADS around thread-related includes.
1122 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
1123 DLSYM_ADDS_USCORE to decide whether to add an underscore.
1125 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1127 * iselect.c (coop_next_runnable_thread,
1128 coop_wait_for_runnable_thread): Disable interrupts so that no
1129 async is executed before a potential error_revive.
1130 (scm_internal_select): Disable interrupts during the parts of the
1131 code which manipulate the sleep queue and the file descriptors.

1138 scm_internal_select.
1139 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1140 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1141 replacement in iselect.c.
1142 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1143 coop_join): If GUILE_ISELECT enabled, use
1144 coop_wait_for_runnable_thread instead of
1145 coop_next_runnable_thread.
1146 (usleep, sleep): New replacements for system functions if
1147 GUILE_ISELECT is enabled.
1149 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1151 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1153 * filesys.c: Added #include "iselect.h". Moved FD-macros to
1154 iselect.h. Implement Scheme level `select' using
1155 scm_internal_select. (See NEWS.)

1164 1997-11-27 Tim Pierce <twp@skepsis.com>
1166 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1167 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1168 and scm_must_free, since ultimately the string returned will be copied
1169 by scm_makfrom0str anyway. Also, read any characters that may have
1170 been pushed onto the port with scm_ungetc.
1171 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1172 * ioext.c (scm_read_line): Free string after Guilifying it.

1177 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
1179 * gh.h: Safely wrap prototypes for c++ usage.
1181 1997-11-25 Mark Galassi <rosalia@cygnus.com>
1183 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
1184 gh_repl (argc, argv).
1186 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1188 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1189 and to invoke scm_shell().
1190 (gh_launch_pad): took out the loading of boot-9.scm from here,
1191 since it is probably best to let the user control that. In fact,
1192 gh_repl() now invokes scm_shell() which does that.
1194 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1196 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()

1218 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1219 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1221 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1223 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1224 configure.in was changed).
1226 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
1228 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1229 * Makefile.in: Regenerated.
1231 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1233 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1234 OPORT is an `open' port, not an output port.
1236 * filesys.c (scm_close, set_element, get_element, scm_chown,
1237 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use

1242 scm_set_port_filename_x, scm_port_mode,
1243 scm_close_all_ports_except, scm_set_current_output_port,
1244 scm_set_current_error_port): Likewise
1245 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1246 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):

1258 Minor problems with substring-related tag changes.
1259 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1260 exactly what we want to leave in to detect substrings.
1261 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1262 * tags.h: Fix diagrams and comments describing the S tag bit;
1263 remove vestigial remarks about the D tag bit.

1265 * strings.c: Formatting tweaks.
1267 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1268 variable first; then SCHEME_LOAD_PATH, with a warning message.
1269 (scm_parse_path): New function.
1270 * script.c: Doc fixes.
1272 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>

1280 * scmconfig.h.in: Regenerated, after change to ../configure.
1282 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1284 * gh.h: gh_vector_set -> gh_vector_set_x
1286 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1288 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1289 with the ! -> _x mapping when going from Scheme to C.
1291 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1293 * gh.h (gh_reverse):

1311 (gh_set_cdr_x): added these routines as I go through and try to
1312 complete the picture R4RS functions that should be mirrored in the
1315 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1317 * tags.h (scm_tc7_substring): Changed the comment and code to
1318 conform with the changes below. Folks! We have suddenly two new
1319 free tc7 codes!!! Jummy, jummy!

1383 * gh_test_c.c (c_vector_test): some improvements on the vector
1386 * gh.h (gh_vector): this used to exist but do the wrong thing.
1387 Now it (almost) does the right thing, though it takes a list
1388 instead of the individual arguments. I need to see how it could
1390 (gh_list_to_vector): added this function as a macro. Corresponds
1391 to Scheme's (list->vector ...).

1399 (gh_make_vector): this used to be (stupidly) called gh_vector().
1400 This is the right name, since it does the same thing as the Scheme
1401 (make-vector ...) procedure.

1420 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1422 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1423 macros should by convention not test for NIMPness.)
1424 (SCM_COERCE_OPORT): Adjust indentation.
1426 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added

1437 printing: Also output hex code of vtable so that type identity
1438 will be indicated as well.
1439 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1440 Removed struct_printer_var; Removed struct-vtable-offset;
1441 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1442 vtable-offset-user): New constants.

1447 the type represented by this vtable.
1449 * print.c (scm_iprin1): Don't print arguments of macro
1450 transformers. (They are always: exp env.); Bugfix: Unmemoize
1451 transformer source with correct environment.
1453 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1455 Streamlining of call-with-dynamic-root:

1460 (cwdr_handler): New function.
1461 (scm_internal_cwdr): New function to perform the function of cwdr
1462 but take args that are more useful to C code. Also, the handler
1463 is now invoked *outside* of the new dynamic root, like the docs
1464 say. We no longer have to catch absolutely all errors, the caller
1465 is responsible for using a handler that does not throw, if he
1467 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1468 * root.h (scm_internal_cwdr): New prototype.
1470 Even more but risky streamlining:
1472 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1473 allocation of the jumpbuf of a root continuation. The changes
1474 below are controlled by it. They are now deactivated.
1475 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1476 the JMPBUF of the scm_rootcont to NULL before returning.
1478 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1479 when they are non-NULL.

1497 (scm_free_print_state): Set `revealed' field to false.
1498 (scm_iprin1): Call user supplied closure printer with
1499 scm_printer_apply. Print in the traditional way when there isn't
1500 one or when it returns #f.
1501 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1502 Accept a port/print-state pair in addition to just a port.
1503 (scm_prin1): Don't return the print_state to the pool when it has
1505 (scm_printer_apply): Set `revealed' field of print_state to true.
1506 (scm_init_print): Set scm_print_state_vtable.
1507 (print_state_fluid, print_state_fluid_num): Removed.

1514 * Makefile.in: Regenerated with automake 1.2c.
1516 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1518 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1519 was looping endlessly.
1521 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1523 * strports.c (scm_eval_string): Don't close the port.
1525 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1526 former returns a nice normal integer. (Thanks to Daniel
1529 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1531 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1532 makefile variable as a build parameter called LIBS. The
1533 build-guile program will use this, for the time being.
1534 * Makefile.in: Regenerated.
1536 Thanks to Shiro Kawai:
1537 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1538 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1541 * Makefile.in: Regenerated with automake 1.2a.
1543 * script.c (scm_compile_shell_switches): If we hit the -c or --
1544 arguments, don't set the car of (command-line) to scm_usage_name,
1545 the prettified name of the guile executable; give it the full
1546 path, the way shells usually handle $0.
1548 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1550 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1551 Scheme-level name `array-map' and renamed `serial-array-map' to
1552 `serial-array-map!'.
1554 * backtrace.c: Introduced exception handlers which now enclose
1555 `display-error' and `display-backtrace' so that error reporting
1556 won't get into infinite loops if an error occurs during displaying
1557 of the error. This can very easily happen with user supplied
1558 print call-back routines.
1560 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1562 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1563 the names `serial-array-map' and `array-map' should be removed.)
1565 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1567 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1568 Added #include "objects.h"
1570 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1571 Add #include "feature.h".
1573 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1574 (modinclude_HEADERS): Added objects.h.
1576 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1577 This test is needed at many places in the code and should be
1578 abstracted. (Motivated by the need of this test in libguiletk.)
1580 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1581 (scm_eval_string), load.c (scm_primitive_load,
1582 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1583 Use SCM_EOF_OBJECT_P.
1585 * eval.c (scm_init_eval): Add feature `delay'.
1587 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1589 * scmhob.h: Removed.
1591 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1593 * list.h (SCM_LISTn): New macros. Make list creation in C code
1594 prettier. The idea comes from STk.
1596 * sequences.h, sequences.c, append.h, append.c: Removed. These
1597 files implemented non-R4RS operations which would encourage
1598 non-portable programming style and less easy-to-read code.
1600 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1603 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1604 sequences.h, #include append.h.
1606 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1609 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1611 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1613 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1615 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1617 * eval.c: Added #include "objects.h"
1619 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1622 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1623 adjacent smob numbers.
1625 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1627 * procprop.h: Added declaration of scm_i_inner_name.
1629 * gsubr.c: New global symbol scm_i_inner_name.
1631 * debug.c (scm_procedure_name): Try procedure property
1632 `inner-name' if `name' fails.
1634 * print.c (scm_iprin1): Use scm_macro_name.
1636 * eval.c (scm_m_define): Give names to macros as well; Only the
1637 first top-level definition gives a procedure/macro a name.
1638 Otherwise confusing names can turn up in backtraces.
1639 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1640 `name'; Give names to macros as well.
1642 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1643 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1646 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1648 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
1650 (prinmacro): Removed. The code has been moved/merged into print.c
1651 in order to decrease code redundancy. We want macros to print in
1652 a way equivalent to procedures, and it would be silly to duplicate
1653 the required code. (We don't want to maintain two places.)
1654 (macrosmob): Print field is now a NULL pointer.
1656 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1657 scm_macro_transformer): New prototypes.
1658 (scm_tc16_macro): Declared.
1660 * * print.c (scm_iprin1): Added code for printing of macros. Macros
1661 are now printed in a way equivalent to procedures.
1663 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1665 * procs.h (scm_closure_p): Added declaration.
1667 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1669 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
1670 Shouldn't pass "heap" as the subr name.
1672 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1674 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
1675 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
1676 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1677 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1678 SCM_BOOL_T. Any non-false value is true.
1680 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1682 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1683 scm_gensym): Added prototypes.
1685 * symbols.c (scm_gensym): New function. This will speed up
1686 certain types of applications (such as macro systems) which
1687 generate lots of symbols.
1689 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1691 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
1693 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
1695 * unif.c (scm_shap2ra): tighten the checking of the array dimension
1696 specifier, since (2) or (2 . 3) would cause SEGV.
1697 (scm_transpose_array): more argument checking fixes.
1699 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1701 * Makefile.in: Regenerated.
1703 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1705 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
1707 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1709 * error.c, error.h (scm_error_callback): Removed (see NEWS).
1711 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
1713 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
1714 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
1717 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
1718 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1719 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
1720 scm_array_p, scm_array_rank, scm_array_dimensions,
1721 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
1722 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
1723 scm_array_prototype): Added case scm_tc7_wvect.
1725 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
1727 * errno.h: prototype for scm_strerror.
1728 * error.c (scm_strerror): new procedure.
1730 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1732 * list.c (scm_list_append_x): Allow non-pair as last argument.
1733 This is consistent with the R4RS append and is probably the
1734 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1736 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1738 * stime.h: prototype for scm_times.
1739 * stime.c (scm_times): new procedure.
1740 * ioext.c (scm_fseek): if the first argument is a file descriptor
1742 (scm_ftell): if the first argument is a file descriptor call lseek
1744 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
1745 * filesys.c (scm_chmod): if the first argument is a file descriptor,
1747 (scm_chown): if the first argument is a port or file descriptor,
1749 (scm_truncate_file): new procedure.
1750 Add DEFER/ALLOW INTS to a few other procedures.
1751 (scm_fsync): new procedure.
1752 (scm_open_fdes): new procedure.
1753 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
1755 (scm_fcntl): the first argument can now be a file descriptor. The
1756 third argument is now optional.
1758 * posix.c (scm_execl, scm_execlp): make the filename argument
1759 compulsory, since omitting it causes SEGV.
1760 (scm_sync): return unspecified instead of #f.
1761 (scm_execle): new procedure.
1762 (environ_list_to_c): new procedure.
1763 (scm_environ): use environ_list_to_c. disable interrupts.
1764 (scm_convert_exec_args): take pos and subr arguments and
1765 improve error checking.
1767 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1769 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1770 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1771 argument to SCM_ASSERT. Furthermore, the name of the function
1772 should be passed as first argument when signalling
1773 SCM_WNA. (Thanks to Thomas Morgan)
1775 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1776 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1777 dispatches on the number of actual args has a default case
1778 reporting an internal error. This is a vestige from a version
1779 that mallocated a SCM vector to hold the arguments. In the
1780 current version this check is too late: if it ever happens we will
1781 have already overstepped the bounds of the array.
1783 Also, the patch [...] adds a check for too many actual arguments."
1785 mdj: Removed check for "internal programming error".
1787 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1789 * gh_io.c (gh_write): New function.
1791 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
1792 throw.c (scm_internal_stack_catch): New sibling to the other catch
1793 functions. Code moved from gh_eval.c.
1794 throw.h: Added header.
1795 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
1796 scm_internal_stack_catch.
1798 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1800 * ioext.h: fix up prototypes.
1801 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
1802 Scheme name is now dup->fdes.
1803 (scm_dup_to_fdes): make the second argument optional and
1804 fold in the functionality of scm_primitive_dup.
1805 (scm_primitive_dup): deleted.
1807 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1809 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
1810 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
1811 ultrix are defined. Use setvbuf instead of setbuf.
1812 (scm_setvbuf): new procedure.
1813 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
1814 (scm_setfileno): moved from ioext.c.
1815 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
1816 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
1818 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1820 * fluids.c (scm_fluid_p): New function.
1821 * fluids.h (scm_fluid_p): New prototype.

1825 * print.c (scm_iprin1): Enter printed structures into the print
1826 state as nested data while they are printed.
1827 (print_state_fluid, print_state_fluid_num): New variables.
1828 (scm_init_print): Initialize them.
1829 (scm_iprin): If print_state_fluid carries a print_state, use that
1830 instead of creating a new one.
1831 (scm_printer_apply, apply_stub, struct apply_data): New
1832 definitions to help with calling printer functions written in
1834 * print.h (scm_printer_apply): New prototype.
1836 * struct.c (scm_print_struct): Use scm_printer_apply to call the
1837 user defined struct printer.
1839 * dynwind.c (scm_dowinds): Handle fluids on the wind list.
1840 * fluids.h (scm_internal_with_fluids, scm_with_fluids,

1845 Fri Jul 25 12:05:46 1997 Marius Vollmer <mvo@zagadka.ping.de>
1847 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
1848 SCM_ASSERT: arg comes before pos.
1850 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1852 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
1853 to a list of length zero correctly.
1855 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1857 Supply an `fgets' method for port objects to do fast line i/o.
1858 * ioext.c (scm_read_line): New function.
1859 * genio.c (scm_gen_read_line): New function.
1860 * fports.c (scm_fgets): New function.
1861 (scm_fptob, scm_pipob): Add scm_fgets method.

1871 * ioext.h: removed scm_duplicate_port prototype.
1873 * ioext.c (scm_primitive_dup2): return the new file descriptor
1874 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
1876 (scm_fdopen): bug fix: don't try to make port unbuffered until its
1877 stream has been set.
1878 (scm_duplicate_port): deleted, there's now an implementation in
1880 (scm_primitive_dup2): do nothing if newfd == oldfd.
1882 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
1884 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
1887 * ioext.h: new prototypes.
1888 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
1890 * fluids.c (next_fluid_num): don't do
1891 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
1893 * ports.h: prototypes too.
1894 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
1896 * fports.h: prototype too.
1897 * fports.c (scm_evict_ports): moved from ioext.c.
1899 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
1901 * ports.c (scm_close_port): return a boolean instead of unspecified.
1902 throw an error if an error other than EBADF occurs.
1904 * filesys.h: scm_close prototype.
1905 * filesys.c (scm_close): new procedure, can close file descriptors
1906 and ports (scsh compatible).
1908 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
1911 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
1913 * fluids.c, fluid.h: New files.
1914 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
1915 (modinclude_HEADERS): Added "fluids.h"
1917 * init.c: Include "fluids.h". (scm_boot_guile_1): Added call to
1918 scm_init_fluids to initialize the fluid machine.
1919 (scm_start_stack): Initialize the fluids of the first root with
1920 scm_make_initial_fluids.

1923 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
1924 (scm_make_root): Call scm_copy_fluids to make fluid bindings
1925 unique for the new root when it has a parent.
1927 * smob.h: Include "libguile/print.h" to make scm_print_state
1930 * dynl.c (free_dynl_obj): New function to free the dynamic object
1931 data. (dynl_smob): Use it.
1932 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
1933 the dynamic object data below the linking of the object to avoid
1934 memory leak when the linking code throws an error. Now the code
1935 leaks a whole dynamically linked library when must_malloc throws,
1936 but that should be much less likely.
1938 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
1940 Changes to compile under gnu-win32, from Marcus Daniels:
1941 * stime.c (tzset): If tzset isn't provided, make it a NOP.
1942 (scm_localtime): Change SCM_EOF to SCM_EOL.
1943 (scm_mktime): Likewise.
1944 * socket.c: Don't include sys/un.h unless autoconf tells
1945 us Unix domain sockets are available.
1946 (scm_fill_sockaddr): Ignore Unix domain code.
1947 (scm_addr_vector): Likewise.
1948 (scm_init_addr_buffer): Likewise.
1949 (scm_socketpair): Don't include unless socketpair was

1952 * scmsigs.c (scm_pause): Don't include unless pause was found
1954 * posix.c (scm_getgroups): Don't include unless support function
1955 was found during autoconf (in this case, getgroups).
1956 (scm_setpwent): For setpwent.
1957 (scm_setegid): For setegid.
1958 * net_db.c (scm_inet_netof): Don't include unless support
1959 function was found during autoconf (in this case, inet_netof).
1960 (scm_lnaof): For inet_lnaof.
1961 (scm_inet_makeaddr): For inet_makeaddr.
1962 (scm_getnet): For getnetent, getnetbyname, getnetbyaddr.

1973 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
1974 scm_misc_error, not SCM_EOF.
1976 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
1977 arguments for formatting the error message, not SCM_BOOL_F. I
1978 think this is left over from the (eq? '() #f) days.
1980 * read.c (recsexpr): Give this a dummy definition if
1981 DEBUG_EXTENSIONS isn't #defined.
1983 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
1985 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
1988 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>

1993 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
1995 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
1996 alloca.lo will be included in @LIBLOBJS@. Something better than
1997 this should be possible.
1998 * Makefile.in: Regenerated.
2000 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2002 * simpos.h: prototype for scm_primitive_exit.
2003 * simpos.c (scm_primitive_exit): new procedure, terminates the
2004 process without unwinding the stack.
2006 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
2008 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
2009 argument and logior its components together, so the user doesn't
2010 have to do this explicitly. Also, if regexp/basic is supplied, then
2011 turn off REG_EXTENDED.
2012 (scm_init_regex_posix): New regexp/basic symbol.
2013 (REG_BASIC): #define this if it is not already present.
2015 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2017 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
2018 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
2019 (CLEANFILES): New target, clean versiondat.h, libpath.h.
2020 (DISTCLEANFILES): New target, clean *.x.
2021 * Makefile.in: Regenerated.
2023 Tue Jun 24 00:29:07 1997 Jim Blandy <jimb@floss.red-bean.com>
2025 * script.c (scm_compile_shell_switches): Add 1997 to copyright
2026 years in usage message.
2028 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
2029 * Makefile.in: Regenerated.
2031 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
2032 flag; I don't think we support it.
2033 (scm_make_regexp): Make sure the user doesn't pass the
2036 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
2038 (scm_init_regex_posix): Define constants for the REG_mumble flags;
2039 name them according to the SCSH convention: regexp/mumble.
2041 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
2043 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
2045 * Makefile.am (libpath.h): Include the values of all the standard
2046 Makefile directory variables. Print a message, but don't print
2048 (versiondat.h): Print a message, but don't print all the commands.
2049 * load.c: #include "alist.h".
2050 (init_build_info): New function.
2051 (scm_init_load): Call it.
2052 * Makefile.in: Regenerated.
2054 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
2056 * root.c: Establish a reliable catch-all handler for the new root.
2057 After all the Scheme handler function might signal an error too,
2058 and we don't want to lose that.
2059 (cwdr_inner_body): Renamed from cwdr_body.
2060 (cwdr_outer_body): New function, to establish the user's handler,
2061 and pass control to cwdr_inner_body.
2062 (cwdr): Establish the reliable catch-all handler here, and pass
2063 control to cwdr_outer_body.
2064 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
2065 the user's handler through to cwdr_outer_body.
2066 * throw.c (scm_handle_by_message): Move guts into....
2067 (handler_message): New static function.
2068 (scm_handle_by_message_noexit): New function.
2069 * throw.h (scm_handle_by_message_noexit): New prototype.
2071 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
2072 across this. Only works on GCC. Otherwise, we hope for the best.
2073 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2074 the feeling that real thread systems will not need this...
2076 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2078 Try to detect when people are using one version of libguile and a
2079 different version of ice-9. People have been skewing things and
2080 sending in bug reports.
2081 * Makefile.am (versiondat.h): New file to generate.
2082 * version.c: #include "versiondat.h", to get version info.
2083 (scm_libguile_config_stamp): New function.
2084 * script.c: #include "version.h".
2085 (scm_compile_switches): Call scm_version to get version number.
2086 * scmconfig.h.in, Makefile.in: Regenerated.
2087 * Makefile.in: Regenerated.
2089 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
2090 primitive definitions under their Scheme names.
2092 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2093 1:2. Helps avoid confusion between installed and uninstalled libs.
2095 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2098 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2099 backslash from definition; this should be used like: GDB_INTERFACE;
2101 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2103 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
2104 new port unbuffered until its stream has been set.
2106 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2108 * ports.h: new prototype.
2109 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
2111 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
2113 Make things compile neatly under Sun's C compiler.
2114 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
2115 * extchrs.c (xmbtowc): Make the second arg a normal char, not
2116 unsigned, because that's what the ANSI function takes.
2117 * extchrs.h (xmbtowc): Corresponding change to prototype.
2118 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2120 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2121 argument plain char *.
2122 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2124 * tag.c (scm_tag): Remove unreachable statement.
2125 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2126 top of the word, it should be unsigned.
2128 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2129 is defined, to avoid warnings; it's only used in the
2130 conflict-checking code. Which might go away anyway.
2131 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2132 conditionals; put the label definition in an #if too, to stifle
2135 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2136 ChangeLog-threads in the distribution.
2137 * Makefile.in: Regenerated.
2139 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2141 * guile-snarf.in: Changed regexp to support CPPs that insert
2142 whitespace between lexical tokens (which munges the `%%%' snarf
2145 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2147 * load.c (scm_init_load_path): Append $(datadir)/guile to
2148 %load-path, so modules do not have to be installed in Guile's
2149 current version directory.
2151 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2153 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2154 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2155 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2156 call the sysdep functions with deferred ints.
2157 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2158 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2159 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2162 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2165 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2167 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2169 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2171 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2174 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2176 * eval.c (scm_lookupcar1): New procedure to cope with a race
2177 condition during lookup (when using threads).
2178 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2179 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2182 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2184 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2185 supplied. (Change from Tim Pierce.)
2187 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2189 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2190 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2191 default and not `()'. `#f' is the canonical non-value in Scheme,
2194 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2196 * struct.c (struct_printer): New variable that holds a handle on
2197 the Scheme variable *struct-printer*. This variable can be set by
2198 Scheme code to override the printing of structures.
2199 (scm_print_struct): If struct_printer is set, call it. If it is
2200 not set, or returns #f, print the structure in the old fashion.
2201 Include "eval.h" for scm_apply.
2203 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2205 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2206 scm_struct_i_n_words to get the number of fields, not
2207 -scm_struct_n_extra_words.
2209 On the route to fancier struct printing:
2210 * struct.c (scm_print_struct): New function to print a structure.
2211 Include "genio.h" to support it. This function doesn't do
2212 anything interesting right now, but I think it should be here
2214 * struct.h: Include "print.h" and add prototype for
2216 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2217 print structures ourself.
2219 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2221 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2222 before applying the handler in case it doesn't return.
2224 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2226 * scmsigs.h, async.h: updated.
2228 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2231 * posix.c (scm_uname): interpret only negative values as an error.
2232 Solaris normally returns a positive value.
2234 * script.c (scm_compile_shell_switches): if we are not going into
2235 an interactive repl, set scm_mask_ints to zero so that asyncs can
2238 * simpos.c (scm_system): don't ignore/unignore signals around
2241 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2244 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2245 done in boot-9.scm instead.
2247 * scmsigs.c, async.c: Major rewriting of signal handling code.
2248 (scm_sigaction): new procedure.
2249 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2251 (scm_raise): return unspecified, throw error on failure.
2253 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2255 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2256 feature, to help boot-9.scm decide whether to import the regex
2259 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2261 * eval.c: Include scmconfig.h at the beginning of the file so that
2262 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2265 * regex-posix.c: #include "_scm.h" before conditionally #including
2266 <regex.h>; the former defines HAVE_REGCOMP.
2268 * regex-posix.c: #include <regex.h> conditionally, so the file is
2269 CPP'able (for dependency scanning) even on systems that don't have
2272 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2274 Add new R4RS-compliant syntax for keywords.
2275 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2276 regardless of the setting of the `keywords' read option.
2277 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2278 can be re-read no matter what the setting of the `keywords' read
2281 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2283 Add support for POSIX regular expressions.
2285 * regex-posix.c, regex-posix.h: New files. (Some code
2286 is taken liberally from rx/rgx.c in the old Guile dist.)
2288 * init.c: Include regex-posix.h.
2289 (scm_boot_guile_1): Call scm_init_regex_posix.
2291 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2292 Add regex-posix.[ch] sources.
2293 * Makefile.in: Regenerated.
2295 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2296 to do this automatically? It didn't for me, bleh.)
2298 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2300 * fports.c (print_pipe_port): New function.
2301 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2302 latter doesn't even take the right arguments.
2304 * Makefile.am: Increment shared lib revision number. I think
2305 sometimes the uninstalled Guile finds the installed shared lib;
2306 Gord says doing this might help. As things turned out, I can't
2307 say whether it does.
2308 * Makefile.in: Regenerated.
2310 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2311 passing it as the closure argument to scm_boot_guile. (Bill
2314 * ports.c (print_void_port, putc_void_port, puts_void_port,
2315 write_void_port, flush_void_port, getc_void_port, close_void_port,
2316 noop0): Use ANSI prototypes instead of K&R declarations, so the
2317 initialization of void_port_ptob gets aggressively type-checked.
2318 Fix arguments of print_void_port and write_void_port. (Bill

2352 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2354 * script.c (scm_find_executable): Use prototype-style definition
2355 here; apparently it's not quite right to have const in a prototype
2356 and then use a K&R declaration. I wonder if stuff like this will
2357 go away if we compile with -Wrequire-prototypes, or whatever that
2358 is... (Bernard URBAN)
2360 * scmhob.h: New text from Bernard URBAN.
2362 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2364 * script.c: Don't #define const on hpux. Configure takes care of
2365 this. (Thanks to Larry Schwimmer.)
2367 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2368 decide whether to #include <unistd.h>, instead of listing a bunch
2369 of systems. Don't #include stdio twice. Removed dyked-out
2370 definition of scm_find_impl_file.
2372 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2374 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2375 library version info to 1:0.
2376 * Makefile.in: Regenerated.
2378 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

2382 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2383 throw.c: Update copyright years; these files have been worked on
2384 significantly in 1997, but only had copyright years for 1996.
2385 Also, change name of copyright holder on some from Mikael
2386 Djurfeldt to Free Software Foundation; he has signed papers
2387 assigning the changes to the FSF.
2389 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2390 reason not to give the user the option.
2392 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2393 Return #f on end-of-file when scanning table (i.e. when called
2394 with no arguments). Try to catch errors, when we can.
2395 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2397 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2398 external declarations. These are useful.
2400 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2402 * posix.c: don't include <sys/select.h> or define macros for
2403 select, since they were not used in this file.
2405 * filesys.c (scm_select): make the fifth parameter microseconds,
2406 not milliseconds. let the fourth parameter be either a real value
2407 or an integer or #f. The first, second and third arguments can
2408 now be vectors: the type of the corresponding return set will be
2410 (set_element, get_element): new static procedures.
2412 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2414 * strports.c (scm_eval_string): New function.
2415 (scm_eval_0str): Trivially re-implemented in terms of
2417 * strports.h (scm_eval_string): New extern decl.
2419 * net_db.c (h_errno): Add extern decl for this.
2421 * fports.c (local_pclose): New function.
2422 (scm_pipob): Use it in the initializer here.
2425 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2426 Use a meaningful error message when signalling an error. For
2427 this, scm_gethost must check h_errno rather than errno.
2429 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2431 * Makefile.in: Regenerated, using automake-1.1p.
2433 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2435 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2436 not SCM_UNSPECIFIED.
2438 * script.c (scm_compile_shell_switches): don't append (quit) if
2440 (scm_shell): call scm_exit_status and exit on the result of the
2443 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2445 Ensure that shared substrings are handled properly when passed to
2446 a system call or other foreign function. Many thanks to Tim
2448 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2449 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2450 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2451 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

2454 (scm_display_error_message): use RO macros when strings may be RO.
2455 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
2456 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
2457 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
2458 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
2459 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
2460 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
2461 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
2462 scm_strftime), vports.c (scm_make_soft_port): use
2463 SCM_COERCE_SUBSTR to make sure shared substrings are

2468 * error.c (scm_error): Add newline to error message.
2470 * init.c (scm_init_standard_ports): Doc fix.
2472 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2474 * dynl-shl.c: Completely replaced with new code from Bernard
2477 * script.c (scm_ice_9_already_loaded): New variable.
2478 (scm_compile_shell_switches): Use it.
2480 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2482 * filesys.c (scm_input_waiting_p): add missing third argument to
2485 * stime.c (scm_localtime): copy the result of localtime before
2486 calling gmtime in case they share a buffer.
2487 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2490 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2492 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2494 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2496 * Makefile.am (check-local): New target, which causes 'make check'
2497 to run gh_test_c and gh_test_repl, with some trivial input.
2498 * Makefile.in: Rgnrtd.
2500 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2502 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2505 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2507 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2508 sure how this was supposed to work.
2509 (scm_async_click): don't send SCM_TICK_SIGNAL.
2510 (scm_init_async): don't initialize %tick-thunk.
2512 * the following change doesn't affect the Scheme interface:
2513 gc-thunk is called at the end of garbage collection. however it's
2514 no longer implemented by pretending it's a signal.
2516 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2517 system async corresponding to scm_gc_thunk.
2518 * async.h: declare scm_gc_async.
2519 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2520 gc-thunk directly, instead of going through a signal handler.
2521 (scm_gc_async): new variable, points to the GC system-async.
2522 (scm_init_async): save the GC async as scm_gc_async instead
2523 of using system_signal_asyncs.
2524 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2526 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2528 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2529 Don't screw up if we're interrupted.
2530 * Makefile.in: Regeneradet.
2532 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2534 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2536 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2537 we're not using AM_INIT_GUILE_MODULE any more.
2538 * Makefile.in: Reneregated.
2540 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2542 Functions for finding variable bindings, grace à Tim Pierce.
2543 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2544 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2546 Get 'make dist' to work again.
2547 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2548 * Makefile.in: Regenerated, like a surry without a fringe on top.
2550 Changes for reduced Guile distribution: one configure script,
2552 * configure.in, configure: Removed.
2553 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2554 real configure script lives.
2555 * Makefile.in, scmconfig.h.in: Regenerated.
2557 * init.c: #include "script.h", to get prototype for script.c's
2560 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2562 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2563 scm_must_malloc, not raw malloc.
2565 * script.c (scm_compile_shell_switches): Dyke out debugging output
2568 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2570 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2572 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2573 system has them. Hope this is safe. Previously
2574 sys/timeb.h was included if HAVE_FTIME was defined or if
2575 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2576 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2578 * ioext.c (scm_setfileno): add missing third argument to
2579 scm_misc_error call.
2581 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2583 * eq.c (scm_equal_p): Correctly compare strings of different
2584 varieties. (Thanks to Tim Pierce.)
2586 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2588 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2589 #! block comment must occur on a line all by itself.
2591 Move most of the guts of shell command processing into libguile,
2592 so guile.c can be very small (and eventuallly auto-generated. (I
2593 mean, generated mechanically, not self-generated. Hmm.))
2594 * guile.c, script.c, script.h: New source files.
2595 * init.c (scm_boot_guile_1): Call scm_init_script.
2596 * libguile.h: #include "script.h".
2597 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2598 targets, for new executable.
2599 (libguile_la_SOURCES): Mention script.c.
2600 (modinclude_HEADERS): Add script.h.
2601 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2602 not dynamic linking is enabled. This is because we're generating
2603 executables now. Move CY_AC_WITH_THREADS call after those, so the
2604 values of cy_cv_threads_libs captures the libs chosen above.
2605 * Makefile.in, configure, aclocal.m4: Regenerated.
2607 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2608 We don't maintain this interface any more, and it just confuses
2611 * alloca.c: #include <scmconfig.h>, not <config.h>.
2612 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2613 it'll get included in disties.
2615 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2617 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2618 be distributed, because they confuse people.
2619 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2621 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2623 * configure.in: check for presence of gethostent (not present on
2624 OpenBSD by default).
2625 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2626 * configure, scmconfig.h.in: Regenerated.
2628 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2630 * backtrace.c (scm_backtrace): Split message string across
2631 newlines properly. GCC is more tolerant of this than other
2634 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
2636 Merge threads directory into libguile.
2637 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
2638 threads.h: New source files.

2640 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2642 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2643 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2644 coop-threads.c.cygnus, coop-threads.h.cygnus.
2645 * configure.in: If we're using threads, include threads.o in
2647 * _scm.h, libguile.h: threads.h lives in this directory now.
2648 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2649 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2650 currently used, but brought along for information's sake.
2651 * ChangeLog-threads: log from old 'threads' directory.
2652 * Makefile.in, configure: Rebuilt.
2654 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2656 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2659 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2661 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2663 Merge GH interface library into libguile.
2664 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
2665 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2666 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2667 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2669 (EXTRA_libguile_la_SOURCES): ... here.
2670 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2671 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2672 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2673 New variables, describing how to build the gh test programs.
2674 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2675 build the test programs, and we probably should have been linking
2676 libguile.la against them all along, to support AIX shared libs.
2677 Add cflags for threads to CFLAGS; add libs for threads to new
2678 variable THREAD_LIBS, used in Makefile.am.
2679 * ChangeLog-gh: log from old `gh' subdirectory.
2680 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2682 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2684 * acconfig.h: Undo change of Apr 9; including the definition of
2685 PACKAGE in the guile headers conflicts with applications' own
2687 * scmconfig.h.in: Regenerated.
2689 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

2693 * filesys.h: Added prototype.
2695 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
2696 when PROC is receiving no arguments.
2698 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2700 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2701 have S_IFSOCK. This is the case under Ultrix.
2703 * posix.c (scm_status_exit_val, scm_status_exit_val,
2704 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2705 Ultrix versions of WIFSTOPPED, etc., which assume that their
2706 arguments are lvalues (hmm).
2708 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2710 * eval.c: Doc fixes.
2712 * throw.c: Doc fixes; rearranged.
2714 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
2716 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
2718 * acconfig.h: Added entry for PACKAGE.
2719 * scmconfig.h.in: Regenerated.
2721 Changes to work with automake-1.1n, which has better libtool support.
2722 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2723 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
2725 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
2727 * Makefile.in: Rebuild.
2729 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2731 * stime.c (scm_mktime): take an optional zone argument.
2732 (scm_localtime): check putenv return value.
2733 (scm_strftime, scm_strptime): moved from posix.c. move #include
2735 stime.h, posix.h: update prototypes.
2736 (bdtime2c, setzone, restorezone): new static procedures.
2737 (scm_mktime, scm_strftime): use them.
2738 (scm_strftime): don't call mktime before strftime. Use
2739 filltime for return value.
2740 (filltime): convert NULL zname to #f.
2741 (scm_strptime): return a count of characters consumed, not
2742 the remaining string.
2744 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2746 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
2747 (scm_mktime): likewise.
2749 Uncomment localtime and mktime.
2751 * configure.in: add AC_STRUCT_TIMEZONE.
2753 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2755 * stime.c (scm_init_stime): don't define ticks/sec.
2756 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2757 return value problem and is still portable.)
2759 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2761 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2762 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2763 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2764 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2765 cpp_err_symbols.c): Corresponding changes.
2766 * Makefile.in: Regenerated.
2768 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2770 * posix.c (scm_putenv): don't check HAVE_PUTENV.
2771 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
2772 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
2773 * putenv.c: new file, from sh-utils 1.12.
2775 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2776 since allocation isn't for Scheme objects.
2777 (scm_putenv): copy strings before placing in the environment.
2779 * stime.c (scm_current_time): throw an error if time returns -1,
2780 instead of returning #f.
2781 (scm_get_internal_real_time, scm_get_internal_real_time): use
2782 scm_long2num for return value instead of SCM_MAKINUM.
2784 * stime.h: prototypes updated.
2786 * stime.c (scm_time_in_msec): apparently unused, deleted.
2788 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2790 * configure.in: check for gettimeofday.
2792 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2793 which may be more usefully portable than a gettimeofday interface.
2795 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2797 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
2799 * Makefile.in: Regenerated.
2801 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2803 * stime.c (filltime): recovered static procedure.
2804 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
2807 * posix.h: add prototype for scm_close_pipe, remove prototypes for
2808 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2810 * posix.c (scm_mknod): split the mode argument into type and perms
2811 arguments, like the extra fields returned by stat.
2813 * fports.c (scm_pipob): set the close, free and print procedures.
2814 (scm_close_pipe): new procedure.
2816 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2817 define them in boot-9.scm
2819 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2821 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
2822 wan't defined. Don't include fd.h.
2824 * Previously fd.h was regenerated whenever configure was run,
2825 forcing a couple of files to be recompiled.
2827 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
2828 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
2829 Check for _fileno as well as _file.
2831 * ioext.c: don't fd.h.
2832 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
2835 * Change the stratigy for getting information about errno
2836 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
2837 generating lists of symbols during the build process, which will
2838 not always work, include comprehensive lists in the distribution.
2839 To help keep the lists up to date, the "check_signals" and
2840 "check_errnos" make targets can be used.
2842 * configure.in: don't check for a command to extract errno codes.
2843 * Makefile.am: update file lists, remove errnos.list and errnos.c
2844 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
2845 check_errnos targets.
2846 (CLEANFILES): remove errnos.c and errnos.list, add
2847 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
2848 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
2849 * errnos.default: deleted.
2850 * cpp_signal.c: new file.
2851 * cpp_errno.c: renamed from errnos_get.c.
2852 * cpp_err_symbols, cpp_sig_symbols: new files.
2853 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
2854 * error.c (scm_init_error): #include cpp_err_symbols instead of
2856 * posix.c (scm_init_posix): don't intern signal symbols. #include
2859 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
2861 * strop.c (scm_i_index): allow the lower bound to be equal to the
2862 length of the string, so a null string doesn't always give an error.
2864 * posix.h: new prototypes.
2865 * posix.c (scm_status_exit_val, scm_status_term_sig,
2866 scm_status_stop_sig): new functions, as in scsh. They break down
2867 process status values as returned by waitpid.
2869 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
2871 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
2872 configure doesn't know about it.
2874 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2876 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
2878 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
2879 which defines C variables with global linkage.
2881 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2883 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
2886 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
2888 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
2889 has time to check why this doesn't work well with continuations.
2891 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
2893 * Fix shell syntax error; some shells won't tolerate
2894 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
2896 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2898 * posix.c (scm_uname): throw an error if uname fails instead
2901 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
2903 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
2906 * async.c (scm_ints_disabled): definition moved from error.c.
2908 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2910 * acconfig.h: Removed PACKAGE.
2912 * scmconfig.h.in: Regenerated.
2914 * snarf.h: g++ says it's non-portable not to specify the first
2915 argument in a varargs declaration. I introduced the first
2916 argument by using preprocessor conditionals.
2918 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
2920 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
2921 (scm_freopen): use RO string macros for filename and modes.
2922 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
2924 * posix.c (scm_getgrgid): simplify conversion of name to C string.
2925 (scm_mknod): use RO string macros for path.
2927 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
2928 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
2930 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2931 use SCM_ROSTRINGP and SCM_ROCHARS.
2933 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2935 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
2938 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
2939 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
2940 support for byte vectors.
2942 * print.c (scm_iprin1): Limit number of vector elements printed
2943 according to pstate->length.
2945 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2947 * backtrace.c (scm_display_error_message): don't segv if message
2950 * error.h: prototype for scm_error_scm.
2952 * error.c (scm_error_scm): new procedure, reimplements scm-error
2953 in C and uses scm_error.
2955 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2957 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
2958 pointer to the Scheme variable read-hash-procedures and intern it
2959 in scm_init_read. Modify scm_read_hash_extend and
2960 scm_get_hash_procedure to use the pointer.
2962 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2964 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
2965 (SCM_KEYWORD_STYLE): defined.
2967 * read.c (scm_read_opts): add a keywords option. This isn't a
2968 boolean option, in case someone wants to add support for DSSSL
2970 Setup scm_keyword_prefix symbol.
2971 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
2973 I've left keyword support disabled by default, since it doesn't
2974 seem to break the module system and it gives R4RS standard behaviour.
2975 It can be reactivated with (read-set! keywords 'prefix).
2977 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2979 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
2980 before constructing arbiter.
2982 * eval.c (scm_m_define): Bugfix: Check that the object is a
2983 closure before setting the procedure property!
2985 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
2987 * ports.c: Removed `ungetc-char-ready?'.
2989 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
2991 * read.c (scm_init_read): intitialise scm_read_hash_procedures
2992 (idea from Mikael: make it a pair so scm_permanent object only
2994 (scm_read_hash_extend): don't call scm_permanent_object.
2995 (ideas from Mikael): if chr is already in the list, replace its
2996 procedure instead of appending it again. If proc is #f, remove
2998 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
3000 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
3002 * gdbint.c (gdb_read): update scm_lreadr usage.
3004 * load.h: update prototypes.
3006 * load.c (scm_primitive_load, scm_read_and_eval_x,
3007 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
3009 * read.h: add prototype for scm_read_hash_extend. Change args for
3012 * read.c (scm_read_hash_procedures): new variable.
3013 (scm_read_hash_extend): new procedure.
3014 (scm_get_hash_procedure): new procedure.
3015 (scm_lreadr): use scm_get_hash_procedure instead of an argument
3016 for extended # processing.
3017 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
3018 scm_read_token): remove case_i, sharp arguments. Change callers.
3020 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
3022 * read.h (SCM_N_READ_OPTIONS): increase to 3.
3023 (SCM_CASE_INSENSITIVE_P): define.
3025 * read.c: add case-insensitive option to scm_read_opts.
3026 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
3027 to determine whether to convert symbol case.
3028 (default_case_i): definition removed.
3029 * read.c (scm_read_token): if case_i, downcase ic before doing
3032 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3034 * configure.in: Added configuration option `guile-debug'.
3035 Configure with --enable-guile-debug if you want a bunch of extra
3036 functions used for debugging when developing Guile.
3038 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3040 * procs.c (make-cclo): New undocumented debugging procedure: Make
3041 compiled closure with internal procedure PROC and length LENGTH.
3042 Only compiled if GUILE_DEBUG is defined.
3044 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3046 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3048 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3050 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3051 with 3 or more args internally to the evaluator.
3053 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3055 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3056 with 3 or more args internally to the evaluator. This is mainly
3057 because we don't want to pass entry and exit points of the
3058 debug support twice, but it also seems to increase the speed of
3059 the evaluator for such calls (e. g. (+ 1 2 3)).
3061 * backtrace.c (scm_display_application): New procedure:
3062 display-application; Set fancy printing parameters individually
3063 for different types of display (backtrace, error, application).
3064 (These should of course be customizable!)
3066 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3067 clear the CHECK-flags.
3069 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3071 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3073 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3075 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3076 from pairs with a GLOC in the car.
3078 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3079 otherwise `symbol-hash' will behave badly.
3080 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3081 we get segmentation fault!
3083 * symbols.c: Added #include "weaks.h". New functions:
3084 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3085 moved to an extraneous library when we split libguile.)
3087 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3089 * filesys.c (scm_stat): stat now takes fport arguments too as
3090 documented in the manual.
3092 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3094 * debug.c (scm_single_step): Bugfix: Call continuation with
3095 scm_call_continuation instead of throwing to it.
3097 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3099 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3100 argument wasn't declared to be optional.
3102 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3104 * stime.c (scm_init_stime): Add feature "current-time".
3106 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3108 * throw.h: prototype for scm_exit_status.
3109 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3110 args to derive an exit status. Allows (quit) to work from a
3112 (scm_exit_status): new function.
3115 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3117 * eval.c (scm_deval): Removed some old code.
3118 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3120 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3123 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3126 * procs.c: Introduce the existent C function scm_thunk_p at the
3127 Scheme level as well.
3129 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3131 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3132 used from C to easily lookup the value of a symbol in the current
3135 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3137 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3138 scm_init_unif in this file. This will also fix a previous problem
3141 * configure.in: Added AM_MAINTAINER_MODE
3143 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3145 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3148 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3150 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3151 source files that are not always included in libguile but should
3152 have their dependencies calculated by automake. This variable is
3153 recognized by automake, no further magic is needed.
3154 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3155 to deal exclusively with *.lo files, as it seems. The *.o files
3156 are built automatically when the corresponding *.lo file gets
3159 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3161 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3164 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3166 * unif.c (scm_array_set_x): minor change to argument error checking.
3168 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3170 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3171 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3172 They should only be included in the library at configure.in's
3174 (libguile_la_LDADD): Include the appropriate .lo files here.
3175 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3176 so we know when to build them (and their .lo bretheren).
3177 * configure.in (LIBLOBJS): New substituted variable. We let
3178 configure decide which .o files to include in LIBOBJS, and then
3179 put the corresponding list of .lo files in LIBLOBJS. The latter
3180 is what we pass to libtool.
3181 * Makefile.in, configure: regenerated.
3183 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3185 * symbols.c (scm_sysintern0): New function. Contains the core of
3186 old scm_sysintern but doesn't take a second value argument.
3187 (scm_sysintern): Now uses scm_sysintern0.
3188 (scm_sysintern_no_module_lookup): Renamed to
3189 scm_sysintern0_no_module_lookup and doesn't take a second value
3190 argument any longer.
3192 * symbols.h (scm_sysintern0: Added declaration.
3194 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3195 scm_sysintern when interning option keys. Otherwise we risk
3196 destroying the values of already interned variables.
3198 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3199 scheme-level boolean (use SCM_NFALSEP).
3201 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3203 (scm_backtrace): New function. (C version of old function from
3204 boot-9.scm) Motivation: Make it possible to display backtraces
3205 without depending on boot-9.scm. (I'm uncertain if this
3206 motivation is good enough...)
3208 * root.h (scm_root_state): Add member the_last_stack_var.
3209 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3211 * root.c (mark_root): Mark scm_the_last_stack_var.
3213 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3216 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3218 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3219 1. mark_lazy_catch didn't mark the smob.
3220 2. Both functions above have standard variants:
3221 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3222 free_lazy_catch --> scm_free0.
3224 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3226 * throw.c (scm_internal_lazy_catch): New function.
3227 (scm_lazy_catch): Rewritten to use it.
3228 (scm_ithrow): Handle the new lazy catch representation.
3229 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3230 that doesn't have a jmpbuf is a lazy catch clause.
3231 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3232 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3233 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3235 (scm_init_throw): Register the new lazy-catch smob type.
3236 * throw.h (scm_internal_lazy_catch): decl for new function.
3238 * throw.c (scm_internal_catch): Doc fixes.
3240 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3241 configure.in. Including this might cause problems if applications
3242 that link against libguile include their own copies of alloca, but
3243 if they're using autoconf, they should be adding libguile to LIBS
3244 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3245 the copy in libguile, and things will be okay. (I think.)
3247 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3249 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3251 strop.h: move prototypes too.
3253 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3255 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3258 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3259 etc. I deleted them from filesys.c long ago, but didn't
3260 notice they were here too (although ineffective since
3261 sys/stat.h wasn't included).
3263 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3265 * eval.c: Don't define alloca in GCC case. gcc will automatically
3266 use __builtin_alloca if appropriate.
3268 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3270 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3271 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3272 that values of automatic variables are preserved. See comments
3273 for safe_setjmp for details.
3275 Change from Thomas Morgan:
3276 * variable.c: Include eq.h.
3277 (var_equal): New function.
3278 (variable_smob): Use var_equal as the discriminator for variables.
3280 * throw.c (s_throw): Remove extraneous declaration.
3282 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3283 * eval.c: Add necessary CPP cruft to support that.
3284 * configure, Makefile.in, scmconfig.h.in: regenerated.
3286 Change from Thomas Morgan:
3287 * procprop.c (scm_procedure_properties): Convert the Scheme
3288 boolean returned by scm_procedure_p into a C boolean before using
3289 it as a condition for SCM_ASSERT.
3290 (scm_procedure_property): Likewise.
3292 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3293 indications of Unixness.
3296 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3298 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3300 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3302 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3303 "unknown # object" error messages.
3305 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3306 (scm_i_index) and declare it static. Add a 'direction' argument
3307 to indicate what way the search should go.
3308 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3310 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3311 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3313 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3315 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3317 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3318 to avoid clash with various scsh forks.
3320 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3322 The following two changes (ramap.c, throw.c) are motivated by the
3323 apparent unportability of forward declarations of static arrays of
3324 the form `static foo bar[];'.
3326 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3327 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3329 * throw.c (scm_throw): Moved above scm_ithrow.
3331 * options.h: Removed the extern declarations of scm_yes_sym and
3332 scm_no_sym since these are static.
3334 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3336 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3338 * Makefile.am: remove AWK=@AWK@.
3339 Add a rule for generating errnos.list.
3340 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3342 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3343 don't extract errnos, just set a variable (avoids the
3344 need to recompile error.c just because configure is run.)
3346 * unif.h: update prototypes.
3347 * unif.c (scm_uniform_array_read,write): change the offset and
3348 length arguments to start and end, for consistency.
3350 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3352 * ioext.h: update prototypes.
3353 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3354 scm_read_line_x, it's a more general procedure using an
3355 interface from scsh. read-line and read-line! are now defined
3357 Note that the new read-line trims the terminator
3358 by default, previously it was appended to the returned string. An
3359 optional argument specifies how to process the terminator (scsh
3360 compatible). For the old behaviour: (read-line port 'concat).
3361 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3362 returns a pair, but is converted to multiple values if the scsh
3365 socket.h: update prototypes.
3366 * socket.c (scm_recvfrom): for consistency with other procedures,
3367 take start and end as separate optional arguments.
3368 (scm_recv, scm_recvfrom): don't allow the second argument
3369 to be a size, only a buffer. Change the scheme names to
3370 recv! and recvfrom!. Don't return the buffer.
3372 * ioext.h, posix.h: move prototypes too.
3373 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3374 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3375 "read.h" and "unif.h".
3376 * ioext.c: include "chars.h"
3378 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3380 * dynl.c: The dynamic linking and module registration functions
3381 are now defined even when dynamic linking is not available for the
3382 host system. Some of their functionality can be done without
3383 dynamic linking; when it's really needed, they throw errors.
3385 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3387 * configure.in: Only define DYNAMIC_LINKING when one of the system
3388 dependent functions is detected.
3389 * dynl.c (scm_dynamic_func): New function to get the address of a
3390 function in a dynamic object.
3391 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3392 produced by scm_dynamic_func as the thing to call.
3394 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3396 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3397 (scm_register_module_xxx, scm_registered_modules,
3398 scm_clear_registered_modules): New functions.
3400 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3402 * symbols.c (scm_sysintern): Renamed to
3403 scm_sysintern_no_module_lookup.
3404 (scm_sysintern): New function to take the place of the old
3405 scm_sysintern. It uses the current toplevel lookup closure to give
3406 the symbol its value. This is a temporary hack to put packages
3407 like gtcltk into their own module.
3408 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3409 us whether `scm_top_level_lookup_closure_var' has been initialized
3411 * eval.c (scm_init_eval): Set it.
3413 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3415 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3416 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3418 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3420 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3421 scm_sys_dup): deleted: FD capability will be added to other
3423 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3424 scm_fd_free, fd_smob, scm_intern_fd.
3425 (scm_open): renamed from scm_sys_open. Return a port instead of
3426 an FD object. Make the mode argument optional.
3427 (scm_sys_create): deleted, it's just a special case of open.
3428 (scm_init_filesys): move interning of constants O_CREAT etc.,
3429 here (were previously using SCM_CONST_LONG macro).
3430 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3432 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3433 include "fports.h" and <stdio.h>
3434 (scm_stat, scm_select): don't support FD objects.
3436 * error.h: adjust scm_syserror_msg prototype.
3437 * error.c (scm_syserror_msg): take an extra argument for errno.
3438 Using the global value didn't always work, since it could be
3439 reset by procedure calls in the message or args arguments.
3441 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3442 I don't understand why the check was there (and what about the
3445 * strop.c (scm_string_copy): allow shared substrings to be copied.
3447 * unif.h: corresponding change to prototypes.
3448 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3449 recognize two new optional arguments: offset and length. Allow
3450 the port argument to be an integer (file descriptor, for scsh).
3451 Include <unistd.h> for "read" prototype.
3453 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3455 * socket.c: don't include filesys.h.
3457 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3459 * Makefile.am: add AWK=@AWK@ (?)
3461 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3463 Add a rule to generate errnos.c from errnos.
3464 * error.c (scm_init_error): include errnos.c.
3465 * errnos_cnvt.awk: new file, converts the list of errno codes to
3467 * errnos_get.c: new file.
3468 * errnos.default: new file, contains errnos to try if they can't
3469 be extracted from errno.h.
3470 * configure.in: if using GCC, try and extract errno codes from
3474 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3476 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3477 * Makefile.am: Made libguile into a libtool library.
3478 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3479 Set libtool_libs to indicate that libguile is a libtool library.
3480 See guile/ChangeLog for details.
3481 * .cvsignore: ignore "*.lo", the libtool library objects.
3483 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3485 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3486 use htons in getservbyport argument.
3488 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3490 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3491 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3494 * objprop.c (scm_object_property): No need to take the CDR of the
3495 value returned by scm_object_properties, since Aug 20 change.
3497 * configure.in: When checking for struct linger, #include
3498 <sys/types.h> as well as <sys/socket.h>. I've never known
3499 <sys/types.h> to cause any portability problems, and Solaris's
3500 <sys/socket.h> needs it.
3501 * configure: Rebuilt.
3503 I think the Sun compiler has chosen a perverse way to interpret
3504 ANSI declarations combined with K&R definitions. We'll
3505 appease it a little bit. But when it invades France, we fight.
3506 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3507 * print.h (scm_iprlist): Here too.
3508 * numbers.c (scm_divbigdig): Change definition to match
3509 declaration in numbers.h.
3510 * unif.c (scm_makflo): Change definition to match declaration in
3513 * init.c (scm_boot_guile): Don't return the value of
3514 scm_boot_guile_1. This function doesn't return a value;
3515 scm_boot_guile_1 doesn't return a value (or return at all).
3517 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3520 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3521 compile. I have a feeling this function is a bad idea anyway ---
3522 one should always test for features, not systems.
3524 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3525 semicolons. Only pure luck kept this from being noticed earlier.
3527 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3529 * socket.c (scm_recvfrom): Added missing semicolon.
3531 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3533 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3534 the buffer and start and end positions for scsh networking
3537 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3539 * configure.in: Revert previous change to this file; the problem
3540 is due to transient automake weirdness.
3541 * configure: Rebuilt.
3543 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3544 PLUGIN/guile.libs. configure generates the latter from the former.
3545 * Makefile.in: Rebuilt.
3547 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3548 need this if we install scripts, like guile-snarf.
3549 * configure: Rebuilt.
3551 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3553 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3555 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3557 * socket.c (scm_addr_vector): fix faulty scm_listify.
3559 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3561 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3562 style block comment is no longer considered an error.
3564 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3566 * PLUGIN/guile.libs.in: New file.
3567 * PLUGIN/guile.libs: Removed from repository.
3568 * configure.in: Create PLUGIN/guile.libs from
3569 PLUGIN/guile.libs.in. This is for including additonal libraries
3570 needed for dynamic linking.
3571 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3572 instead of PLUGIN/guile.libs.
3574 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3576 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3578 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3579 occurrences of the given element from the list, not just the
3580 first. This is how the Emacs Lisp functions behave, how the
3581 analogous Common Lisp functions behave, and (I believe) how the
3582 older Maclisp functions worked. I realize that this change may
3583 break code, but it seemed better to break it before the Guile
3586 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3587 Their prototypes were already present in gc.h, but they weren't
3589 (scm_init_storage): Initialize scm_protects.
3590 * root.c (scm_protects): New element of scm_sys_protects.
3592 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3594 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3596 * libguile.h: Added #include "libguile/net_db.h".
3598 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3599 30 change. That file is only meant for communication between the
3600 configuration process and load.c. If code linked against libguile
3601 wants to get at the paths mentioned in libpath.h, it can call
3602 functions declared in load.h.
3604 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3606 * libguile.h: Removed #include "libguile/fdsocket.h"
3608 * net_db.c: Added #include <sys/socket.h>.
3610 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3612 * filesys.c (scm_input_waiting_p): use select in preference to
3613 FIONREAD, since the latter doesn't detect EOF.
3614 Throw error if neither select nor FIONREAD available.
3616 * socket.c (scm_connect): take a port, not a fd object.
3617 (scm_fill_sockaddr): throw an error if fam is not recognised.
3618 (scm_bind): use scm_fill_sockaddr.
3619 (scm_listen): take a port, not a fd object.
3620 (scm_accept): take and return a port. return #f in the car if
3621 address can't be got
3622 (scm_sock_fd_to_port): new procedure.
3623 (scm_socket): use scm_sock_fd_to_port.
3624 (scm_addr_vector): throw error if unrecognised address type.
3625 take an extra argument with the calling procedure name.
3626 (scm_getsockname): take a port. return #f if address can't be got.
3627 (scm_getpeername): take a port. return #f if address can't be got.
3628 (scm_recvfrom): take a port. return #f for address component if can't
3630 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3631 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3633 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3635 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3636 use separate data pointers, to allow them to be designed
3637 independently and reused.
3638 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3639 Renamed from catch_body, catch_handler, and uncaught_throw; made
3641 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3643 (scm_catch): Use the above.
3644 (scm_throw): Don't bother printing a message for an uncaught
3645 throw; we establish a default handler in init.
3646 * throw.h (scm_internal_catch): Prototype updated.
3647 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3649 (struct scm_body_thunk_data): New structure, used as data
3650 argument to scm_body_thunk.
3651 * init.c (struct main_func_closure): New structure, packaging up
3652 the data to pass to the user's main function.
3653 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3654 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3655 scm_internal_catch to establish a catch-all handler, using
3656 scm_handle_by_message. This replaces the special-case code in
3658 (invoke_main_func): Body function for scm_internal_catch; invoke
3659 the user's main function, using the main_func_closure pointer to
3660 decide what to pass it.
3661 * root.c (struct cwdr_body_data): Remove handler_proc member.
3662 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3663 (cwdr_handler): Removed.
3665 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3667 * socket.h (SCM_P): update bind prototype.
3668 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3669 include "feature.h".
3670 (scm_socket): return a port, not a file descriptor object.
3671 include "fports.h" and <unistd.h>
3672 (scm_bind): take a port, not a file descriptor object.
3673 take an extra argument for address args.
3675 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3676 INADDR_NONE, INADDR_LOOPBACK.
3678 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3680 * init.c: include net_db.h and not fdsocket.h.
3681 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3683 * Makefile.am: corresponding changes.
3684 * socket.h: renamed from fdsocket.h, fix names.
3685 * net_db.h: renamed from socket.h, fix names.
3686 * socket.c: renamed from fdsocket.c.
3687 remove _sys from procedure names.
3688 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3689 add "socket" to features list.
3690 * net_db.c: renamed from socket.c.
3691 remove _sys from procedure names.
3692 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3693 add "net-db" to features list.
3694 include "net_db.h". don't include <sys/socket.h> or
3697 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3699 * tags.h (scm_tags): Removed comma at end of last enumerator.
3701 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3703 Don't use GCC extensions to allocate space for debugging frames.
3704 (Here he goes again! Why do we put up with this?!)
3705 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3706 an scm_debug_info structure, not an in-line array of them. Add
3707 'info' member, to say how many vect elements we've used, for eval
3709 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3710 a new variable debug_info_end to mark the end of vect, instead of
3711 the address of the 'info' pointer itself.
3712 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3713 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3714 (SCM_APPLY): Explicitly allocate space for debug.vect.
3715 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3716 * stacks.c: Adjusted for new debug frame structure.
3717 (RELOC_INFO, RELOC_FRAME): New macros.
3718 (stack_depth, read_frames): Use them, and new scm_debug_frame
3719 element 'info', instead of magically knowing that eval frames have
3720 an info pointer sitting after vect.
3721 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3723 (scm_init_stacks): Formatting tweaks.
3725 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3727 Give GCC more control flow information, so it can be sure that
3728 variables aren't used uninitialized.
3729 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3730 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3731 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3732 scm_misc_error): Tell GCC that these functions never return.
3733 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3734 out the field type, call abort if SCM_ASSERT returns, to placate
3736 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3737 scm_wta ever returns. We can't handle this case anyway, and this
3738 gives the optimizer more information.
3739 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3740 scm_wta ever returns.
3742 In some cases, the code is fine, but GCC isn't smart enough to
3743 figure that out; this usually happens when one variable is only
3744 initialized and used when a particular condition holds true, and
3745 we know that condition will never change within a given invocation
3746 of the function. In this case, we simply initialize the variables
3747 to placate the compiler, hopefully to a value which will cause a
3748 crash if it is ever actually used.
3749 * print.c (scm_iprin1): Initialize mw_pos.
3750 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3751 * throw.c (scm_ithrow): Initialize dynpair.
3752 * unif.c (scm_uniform_vector_ref): Initialize cra.
3753 * struct.c (init_struct): Initialize prot.
3754 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3756 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3757 if EXPR contains no expressions.
3759 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3761 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3762 cause an infinite loop (???). So much for the algebraic
3763 equivalency of variable-sized arrays and alloca...
3765 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3767 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3768 a SCM boolean, not a C boolean.
3770 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3772 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3773 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3774 rules for raising scm_mtrigger. Previously, unfortunate but not
3775 unlikely circumstances could result in almost constant invokation
3776 of the gc. Now, this situations should be less likely, but they
3777 are not prevented completely.
3779 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3781 * numbers.c (scm_fuck): Procedure removed; looks like old test
3783 * numbers.h: Prototype removed.
3785 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3787 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3788 array to a pointer, to match my Nov 21 change in eval.c.
3790 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3792 * libguile.h: Added #include "libguile/backtrace.h", #include
3793 "libguile/stacks.h".
3795 * strings.c (scm_string scm_make_string scm_string_ref
3796 scm_string_set_x scm_string_equal_p scm_string_append):
3797 Bugfix according to scm patch from Aubrey Jaffer:
3798 Corrected long-standing
3799 (not (eqv? (integer->char 128)
3800 (string-ref (make-string 1 (integer->char 128)) 0)))
3801 bug found by John Kozak <jk@noontide.demon.co.uk>.
3803 * strports.c, strports.h: Make scm_eval_0str return the value of
3804 the last expression evaluated (previously, it returned void).
3806 * strports.c, strports.h: New function: scm_read_0str. Does what
3809 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3811 * simpos.c (scm_getenv): return #f if string can't be found in the
3812 environment instead of throwing an exception, for compatibility
3813 with numerous other systems.
3815 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3817 * Makefile.am (.c.x): Use guile-snarf.
3818 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
3820 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
3822 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3824 * backtrace.c (scm_display_error_message): Made non-static, and
3825 renamed from display_error_message.
3826 * backtrace.h (scm_display_error_message): Added extern decl.
3827 * throw.c (uncaught_throw): Use it to display the error message.
3829 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
3831 * inet_aton.c: Use #if 0, not #ifdef 0.
3833 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
3835 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
3836 to convert the returned value.
3837 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
3838 the offset argument.
3840 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3842 Add new interface to catch/throw, usable from C as well as
3844 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
3845 (scm_internal_catch): New function, replaces...
3846 (scm_catch_apply): Deleted.
3847 * throw.c (scm_catch_apply): Deleted; replaced with a more general
3848 mechanism which is a bit more code, but can be used nicely from C
3849 and implement the Scheme semantics as well.
3850 (scm_internal_catch): This is the replacement; it's named after
3851 the analogous function in Emacs.
3852 (scm_catch): Reimplemented in terms of the above.
3853 (struct catch_body_data, catch_body, catch_handler): New
3854 functions, used by scm_catch.
3855 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
3856 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
3857 support for new cwdr.
3859 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
3862 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
3864 * acconfig.h: Added DYNAMIC_LINKING symbol.
3865 * configure.in: Add option and checks for dynamic linking.
3866 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
3867 dynl.h: New files for dynamic linking support.
3868 * Makefile.am (libguile_a_SOURCES):
3870 (modinclude_HEADERS): Added "dynl.h".
3871 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
3873 * init.c (scm_boot_guile_1): Call
3874 scm_init_dynamic_linking to initialize dynamic linking support.
3876 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
3878 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
3879 (as we Schemers say). It needs to be global, so that I can tweak
3880 it for the proper operation of unexec.
3881 (scm_boot_guile_1_live): New variable, see above.
3883 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
3885 * guile-snarf.sh: Removed.
3886 * PLUGIN/guile.libs: Added dependency for -lm.
3887 * acinclude.m4: Renamed from aclocal.m4.
3888 * PLUGIN/greet: Removed.
3889 * Makefile.am, aclocal.m4: New files.
3890 * configure.in: Updated for Automake.
3892 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
3894 * eval.c (scm_definedp): Use top_level_lookup_closure_var
3895 and not top_level_lookup_thunk_var.
3897 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
3899 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
3901 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
3903 * eval.c (scm_definedp): Incompatibly changed to be a builtin
3904 Scheme function, instead of syntax. Single argument is now a
3907 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3909 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
3910 scm_ra_divide): Properly terminate statements passed as arguments
3911 to IVDEP macros. (Thanks to Bernard Urban.)
3913 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
3914 with non-constant sizes. (Thanks to Bernard Urban.)
3916 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3918 It's an "eval closure", not an "eval thunk." A thunk is a
3919 function of no arguments.
3920 * root.h (struct scm_root_state): Renamed
3921 top_level_lookup_closure_var from top_level_lookup_thunk_var.
3922 (scm_top_level_lookup_closure_var): Renamed from
3923 scm_top_level_lookup_thunk_var.
3924 * root.c (mark_root): Uses changed.
3925 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
3926 * init.c (scm_start_stack): Uses changed.
3927 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
3928 Change scheme-visible name to *top-level-lookup-closure* from
3929 *top-level-lookup-thunk*.
3931 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
3933 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
3934 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
3936 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
3938 * gc.c (struct scm_heap_seg_data): Doc fixes.
3940 * gc.c (scm_gc_sweep): Empty all segments' freelists before
3941 sweeping. Then, prepend each segment's free cells to its
3942 freelist, rather than wiping out the old value. (Thanks to Marius
3945 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
3946 scm_check_freelist, scm_debug_newcell): New functions and
3947 variables, for debugging freelist problems.
3948 * pairs.h (SCM_NEWCELL): New debugging version added.
3949 * gc.h (scm_debug_newcell): Added extern declaration, used by
3950 debugging version of SCM_NEWCELL.
3952 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3954 On some systems <libc.h> conflicts with <unistd.h>, and should not
3955 be #included at all.
3956 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
3957 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
3958 * configure.in: Call it.
3959 * posix.c, filesys.c: Use its results to decide whether or not to
3961 * configure, scmconfig.h.in: Rebuilt with autoconf and
3964 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
3966 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
3967 pointer to the stdio stream before calling scm_setbuf0, so the
3968 latter will be able to retrieve it. I'm surprised this didn't
3969 segfault earlier. (Thanks to Christopher Lee.)
3971 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3973 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
3976 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3978 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
3979 number of stack narrowing specifier pairs. The first specifier in
3980 a pair controls inner border, the second the outer border. A
3981 number means cut that number of frames, a procedure object means
3982 cut until that object is found in operator position in a frame.
3984 * root.c (cwdr): Bugfix.
3986 * read.c: Recording of positions disabled by default.
3988 * procs.c (scm_closure_p): New function.
3990 * posix.c (scm_tmpnam): New function.
3992 * load.c: Added #include "throw.h".
3993 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
3996 * load.c, load.h (scm_read_and_eval_x): New function.
3998 * eval.c: Renamed debug option "deval" to "debug".
4000 (scm_eval_x): `eval!' is no longer accessible from the scheme
4001 level. Motivation: We can't allow operations which introduce
4002 glocs into the scheme level. Guile's type system can't handle
4003 these as data. Use `eval' or `read-and-eval!' as replacement.
4005 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
4006 SCM_CONSP since this is a macro!; Set vframe.prev to
4007 scm_last_debug_frame instead of 0. In this way we can look
4008 "above" the virtual start stack frame if we wish.
4009 (scm_debug_hang): New function: Useful for debugging Guile in
4010 certain tricky situations. Will probably be removed later...
4012 * debug.h: Changed semantics of debug option "backtrace". This
4013 option now only indicates whether we want automatic backtrace at
4016 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4018 * ports.c: #include "filesys.h"
4019 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
4021 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
4022 Motivation: This is system specific code which is related to file
4023 I/O. It also may use select. Added code by Gary Houston to
4024 detect presence of character in stdio buffers.
4026 * libguile.h: #include "libguile/libpath.h"
4028 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4029 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4030 SCM_SITE_DIR; Install libpath.h among the other include files.
4032 * load.c, load.h (scm_sys_package_data_dir): New function.
4034 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4036 * stacks.h: Bugfix: Don't use tail-array length field as stack
4037 length field! This screwed GC.
4039 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4041 * _scm.h: Added #ifndef around definition of macros min and max.
4043 * __scm.h: Added hooks for threads to plugin to in ints protection
4044 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4045 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4046 the main code in these macros duplicated and spread over multiple
4047 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4048 SCM_THREAD_SWITCHING_CODE.
4050 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4052 * snarf.h: New file.
4053 * guile-snarf.sh: New file.
4054 * Makefile.in (inner_h_files): Added snarf.h
4055 (ancillary, install, uninstall, distclean): Added actions for
4057 (.c.x): Use guile-snarf.
4058 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4059 (gen_c_files): Note that these depend on guile-snarf.
4060 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4061 now in "snarf.h". Added #include "snarf.h" to get them.
4062 * libguile.h: Added #include "snarf.h".
4063 (Patches applied and tweaked by Jim Blandy.)
4065 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4067 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4068 standards suggest against providing prototypes for system
4069 functions. Thanks to Greg Troxel.
4071 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4073 * strports.c (scm_eval_0str): New function.
4074 #include "read.h", to get prototype for scm_read.
4075 * Makefile.in (strports.o): Update dependencies.
4076 * strports.h: New prototype.
4078 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4079 scheme name from "int?" to "integer?". It seems to do the job.
4080 * numbers.h: Rename prototype too.
4081 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4084 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4085 scm_num_eq_p): Rename these according to R4RS conventions: call
4086 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4087 to making libguile R4RS compliant without ice-9...
4089 * load.c (scm_sys_search_load_path): Search for files under all
4090 extensions listed in the %load-extensions variable. If FILENAME
4091 is absolute, return it unchanged, without searching the load path.
4092 (scm_loc_load_extensions): New variable, pointing to
4093 %load-extensions' value cell.
4094 (scm_init_load): Initialize it, and the value it points to.
4095 (scm_primitive_load_path): Improve error reporting.
4097 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4098 of new Scheme variable %load-hook.
4099 (scm_primitive_load): Apply %load-hook to filename.
4101 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4103 * configure.in: add tests for figuring out whether buffered data
4104 is available in a FILE structure, which is needed by char-ready.
4106 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4109 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4110 exceptions using misc_error instead of syserror. It seems a bit
4111 odd to throw an exception if a string can't be found in the
4112 environment, but it's consistent with open-file, stat etc.
4113 (simpos.h): remove sys_ from getenv.
4115 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4116 occurs, throw an error instead of returning errno. Return value
4118 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4120 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4122 * filesys.c (scm_stat2scm): derive file type and permissions from
4123 the stat mode and append them to the returned vector.
4124 There isn't much overhead in doing this and it avoids the need to
4125 work with S_IRUSR et al. in Scheme.
4126 Define symbols scm_sym_regular etc.
4127 (scm_init_filesys): don't intern S_IRUSR etc.
4129 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4130 and s_primitive_load_path.
4132 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4134 * error.h: don't declare error symbols. prototype for scm_misc_error.
4136 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4139 * error.c: use SCM_SYMBOL to set up error keys.
4140 scm_misc_error: new procedure.
4142 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4144 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4145 between `#!' and `!#' is ignored.
4146 (skip_scsh_block_comment): New function.
4148 * feature.c (scm_set_program_arguments): New argument, FIRST.
4149 * feature.h: Update prototype.
4150 * init.c (scm_boot_guile_1): Pass new argument to
4151 scm_set_program_arguments.
4153 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4155 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4156 (scm_boot_guile): Call scm_set_program_arguments here, later than
4157 the old initialization.
4159 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4160 initialization procedure.
4161 - Delete in, out, err arguments; there are other perfectly good
4162 ways to override these when desired.
4163 - Delete result argument; this function shouldn't ever return.
4164 - Rename init_func argument to main_func, for less confusion.
4165 - Delete boot_cmd argument; main_func is more general.
4166 -Add 'closure' argument, to help people pass data to main_func
4167 without resorting to global variables.
4168 - Abort if reentered; don't bother returning an error code.
4169 - Call scm_init_standard_ports to set up the default/current
4170 standard ports; no need to pass them to scm_start_stack.
4171 - Remove code to evaluate the boot_cmd, and start the repl; let
4172 the user do something like that in main_func if they want.
4173 - Remove code to package up a return value; main_func can do any
4175 - Call exit (0), instead of returning.
4176 (scm_start_stack): Don't initialize the I/O ports here; that's
4177 weird. Delete in, out, err arguments. Move guts to
4178 scm_init_standard_ports, scm_stdio_to_port.
4179 (scm_init_standard_ports): New function, to set up current and
4180 default standard ports.
4181 (scm_start_stack, scm_restart_stack): Make these static.
4182 * init.h (scm_boot_guile): Adjust declaration.
4183 (scm_start_stack, scm_restart_stack): Remove externally
4184 visible declarations for these.
4185 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4187 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4188 written out several times in scm_start_stack.
4189 * fports.h: New declaration for the above.
4191 * feature.c (scm_set_program_arguments): New function.
4192 * feature.h: New declaration for the above.
4194 * ports.c: Formatting tweak.
4196 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4198 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4199 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4200 for obtaining the address of a car or cdr field. Motivation:
4201 &SCM_CXR make assumptions about the internal structure of the
4204 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4205 Motivation: see SCM_CXRLOC.
4207 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4208 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4209 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4210 Motivation: Safer use. Some other macros are defined in terms of
4211 these operations. If these are defined using the SCM_SETCXR
4212 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4213 to inefficiency and an <e1> with side-effects could potentially
4214 break. Also, these particular operations are heavily utilized in
4215 the garbage collector. In unoptimized code there will be a
4218 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4219 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4220 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4221 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4222 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4223 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4224 vports.c: Cleaned up use of pairs: Don't make any special
4225 assumptions about the internal structure of selectors and
4226 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4227 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4228 (Among other things, this change makes it easier to build Guile
4229 with certain compilers which have problems with casted lvalues.)
4231 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4233 * stacks.c: Improve selection of relevant stack frames when making
4234 a stack object. Introduce one level of indirection in the stack
4235 object to make it possible to "narrow" to a certain region of the
4236 stack. This facilitates making use of more clever algorithms (not
4237 implemented) for selecting relevant frames and gives a cleaner
4238 design since selection of frames can be done independently of
4239 extraction of frames from the real stack.
4240 (scm_stack_id): Also take #t as argument which means look at
4243 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4244 Turn n_tail into an integer directly representing current number
4245 of frames in stack. Add field tail.
4247 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4249 * debug.c (scm_make_memoized): Made it available at scheme level.
4250 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4251 SCM_NIMP before applying heavier predicates in argument checking.
4252 (scm_local_eval): Also take memoized object as argument.
4254 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4255 aren't created with zero length, but should such a strange
4256 creature suddenly turn up...
4258 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4260 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4261 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4263 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4265 * variable.c (scm_make_variable): Make the name hint optional, as
4267 (anonymous_variable_sym): Renamed from variable_sym. All uses
4270 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4271 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4272 of scm_primitive_load_path was also changed to
4273 "primitive-load-path", from "%try-load-path". Callers changed.
4274 We'd like to respect the convention that a function named
4275 "try-mumble" should behave just like the function called "mumble",
4276 but return #f instead of signalling some error.
4277 * load.h: Rename prototypes.
4279 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4281 * print.c (make_print_state, grow_print_state), print.h: Modified
4282 the print state representation: Don't use a tail array for
4283 recording of circular references. Resizing of the print state
4284 structure invalidates the print state pointer. To avoid passing
4285 around an indirect print state reference to all printing
4286 functions, we instead let the print state reference a resizable
4289 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4291 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4292 Don't crash when passed an improper list terminated by a
4293 non-immediate value.
4295 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4297 Allocate data for structures on an eight-byte boundary, as
4298 required by the tagging system.
4299 * struct.c (alloc_struct): New function.
4300 (scm_make_struct, scm_make_vtable_vtable): Call it.
4301 * struct.h (scm_struct_n_extra_words): Bump to 3.
4302 (scm_struct_i_ptr): New "field".
4303 * gc.c (scm_gc_sweep): When we need to free the data, use the
4304 information stored by alloc_struct to find the beginning of the
4305 block allocated to the structure, so we can free it.
4307 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4309 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4312 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4313 (scm_debug_info): New member: id.
4315 * stacks.c: Stacks are now represented as structs; Stacks have an
4316 id given to them by `start-stack'.
4317 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4319 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4320 Changed stack representation.
4322 * debug.c (scm_procedure_name): Try procedure property `name' for
4323 compiled closures aswell.
4325 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4327 * eval.c: scm_i_name moved to gsubr.c
4328 (scm_m_define): Record names of all kinds of procedure
4329 objects. (Earlier, only closures were recorded.)
4331 * procprop.h: Added declaration of scm_i_name.
4333 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4334 (scm_make_gsubr): Record names of compiled closures.
4336 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4338 * debug.c, debug.h: Removed obsolete code.
4340 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4341 stacks.c: Renamed regs --> scm_contregs.
4343 * print.c (scm_free_print_state): Cleanup print state before
4344 returning it to pool. It is better to do it here than in
4345 scm_prin1 since scm_prin1 is called often.
4347 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4348 s_set_source_property_x): Check that first argument is a pair or a
4351 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4352 scm_i_line, scm_i_column and scm_i_breakpoint global.
4354 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4355 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4358 * debug.h: Added debug object smob declaration and macro
4361 * configure.in: Build with backtrace.o and stacks.o if debug
4364 * Makefile.in: Added entries for new files: backtrace.c,
4365 backtrace.h, stacks.c and stacks.h.
4367 * symbols.c (scm_sym2ovcell): Fixed documentation.
4369 * _scm.h (min, max): Added.
4371 * async.c: Moved `min' macro to _scm.h.
4373 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4374 SCM_BACKTRACE_INDENT.
4376 * eval.c: Added new debug options `maxdepth' and `indent'.
4378 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4380 * print.h: Added selector SCM_PRINT_STATE.
4382 * print.c: New functions: scm_make_print_state,
4383 scm_free_print_state.
4385 * print.h: Added declarations for scm_make_print_state,
4386 scm_free_print_state.
4388 * debug.c (scm_m_start_stack): New acro.
4390 * debug.h: Small cleanup.
4392 * init.c (scm_boot_guile_1): Moved scm_init_debug below

4417 declare functions with prototypes. (Patch thanks to Marius
4420 More prototype-related changes from Marius Vollmer:
4421 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4422 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4423 * ports.h (ptobfuns): Added prototypes. This means some casting in
4425 * fports.c: Added casts for initializations, since the functions
4426 are defined to take FILE * as their stream argument, not SCM.
4427 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4428 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4429 to `char *str_data' to conform to prototype.
4431 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4433 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4435 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4437 * stime.c, stime.h: use SCM_P method.
4439 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4441 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4442 be given at least two arguments. Insist that lst's last element
4443 be a list, but don't make any requirements of its predecessors.
4445 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4447 * eval.c (scm_nconc2last): Revert last change; there seems to be
4448 other stuff going on here.
4450 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4452 * eval.c (scm_nconc2last): Make sure that each element of lst
4453 (which is a list of argument lists, except for the tail) is a
4454 proper list, i.e., finite and terminated by '().
4456 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4458 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4461 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4462 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4465 * vectors.c (scm_make_vector): Fill vectors with the undefined
4466 value, to help make Guile Scheme code more portable to other
4469 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4470 * symbols.h, tags.h: Doc fixes.
4472 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4474 * async.c (scm_take_signal): Doc fixes.
4476 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4478 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4479 want to subtract it from the modulus; we just want to leave it
4482 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4484 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4487 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4489 * throw.c (scm_catch_apply): Finished implementation of
4492 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4494 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4496 (scm_init_filesys): set "i/o-extensions" feature.
4499 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4501 * Makefile.in (root.o): Correct dependencies.
4503 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4505 * Makefile.in: Added dependency entry for root.o.
4507 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4508 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4510 * init.c (scm_start_stack): Set initial root continuation number
4513 * procs.c: New function: scm_thunk_p.
4515 * procs.h: Added declarations of scm_thunk_p.
4517 * root.c: Renamed `call-with-new-root' -->
4518 `call-with-dynamic-root'.
4519 (cwdr): Removed allocation of new root state. This should be done
4520 separately by use of scm_make_root.
4521 (scm_apply_with_dynamic_root): New function: Does what it
4522 sounds like. Needed when spawning threads.
4524 * root.h: Added member last_debug_frame to root state.
4525 Added #include "libguile/debug.h"
4527 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4528 arguments. The motivation is that code in root.c needs catch
4529 functionality, and we want to avoid code duplication.
4530 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4531 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4532 handlers that run without popping the stack into the dynwind
4535 * throw.h: Added prototypes for scm_catch_apply and
4538 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4540 * root.h (scm_root, scm_set_root): Decouple thread support details
4541 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4542 SCM_SET_THREAD_LOCAL_DATA.
4544 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4545 and tortoise scanning loop.
4547 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4549 * Makefile.in: Rebuild dependencies.
4551 * libguile.h: #include "libguile/print.h" before "smob.h", since
4552 the latter uses the print_state structure.
4554 * throw.c (scm_ithrow): Use the correct variable when checking to
4555 see if a given element of scm_dynwinds is a valid catch.
4557 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4558 structure, abort; don't just silently ignore the garbage.
4560 * _scm.h: #include "print.h" here, since it seems to be used just
4562 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4563 strports.c, unif.h: Don't #include "print.h".
4565 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4567 * feature.h (scm_loc_features): Removed external declaration.
4568 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4570 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4572 * feature.c (scm_init_feature): Added threads feature (needs to be
4573 initialized here, since features doesn't exist when
4574 scm_init_threads is called).
4576 * libguile.h: Added #include "libguile/../threads/threads.h".
4577 (This is a kludge to get thread support working. This should be
4580 * configure.in, acconfig.h: Added flags for thread support.
4582 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4585 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4586 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4589 * _scm.h: Added conditional #include "threads.h"
4591 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4592 SCM_THREADS_SWITCHING_CODE.
4594 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4595 allocate the basic dynamic root object.
4596 (scm_boot_guile): Added call to scm_init_root.
4598 * root.c, root.h: Added root smob.
4599 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4600 functions: Implements dynamic roots mostly according to spec in
4601 SCM manual. Main difference is that the second argument is a
4602 throw handler rather than an error "thunk".
4604 * root.h: Added declaration of scm_init_root.
4606 * root.c: Added #include "genio.h", #include "smob.h", #include
4607 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4609 (scm_init_root): Added #include "root.x".
4611 * throw.c: Added #include "stackchk.h"
4612 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4613 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4614 can be used in scm_call_with_new_root; Added reenabling of stack
4615 checking when catching a throw.
4617 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4619 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4621 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4622 element is not found, as per R4RS.
4624 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4626 * list.c: Doc fixes throughout.
4628 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4630 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4631 declare the char * to be const. Avoids a warning in rgx.c.
4633 * ports.h: spelling fix.
4635 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4638 * load.c (scm_sys_try_load_path): throw an error if file not found
4639 (like it says it in NEWS).
4641 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4643 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4644 PROPS slot to '(), not #f; it's an empty alist.
4646 * throw.h, throw.c: Use SCM_P instead of #if hair.
4648 Remove special support for uncaught throws; see throw.c for
4650 * throw.c (uncaught_throw): New function.
4651 (scm_ithrow): Call uncaught_throw if we don't find a throw
4652 target; don't mess with scm_bad_throw_vcell.
4653 (scm_bad_throw_vcell): Variable deleted.
4654 (scm_init_throw): Don't initialize it.
4656 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4659 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4661 * numbers.c (scm_istr2int): If the number is short (as most
4662 numbers are), just call scm_small_istr2int to deal with it.
4663 (scm_small_istr2int): New function, created by un-#ifdefing the
4664 non-bignum version of scm_istr2int and renaming it.
4666 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4668 * load.c (scm_sys_try_load): don't check whether value returned
4669 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4670 Change the Scheme name from %try-load to primitive-load.
4672 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4673 Can avoid passing a message, allowing it to be derived in the
4674 error handler (e.g., if we want to throw to the key both from
4677 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4679 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4680 references now have a new appearance which is more compact and
4681 also gives a clue about what the target of the reference is.
4682 By setting parameters in the print state, more fancy printing can
4683 be achieved. This is used by the (not yet commited) backtrace
4686 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4688 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4691 * print.c: Added #include "struct.h". Removed function
4694 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4695 scm_iprin1. Removed prototype for scm_prlist.
4697 * arbiters.c (prinarb),
4698 async.c (print_async),
4699 debug.c (prindebugobj, prinmemoized),
4700 eval.c (prinprom, prinmacro),
4701 filesys.c (scm_fd_print, scm_dir_print),
4703 mallocs.c (prinmalloc),
4704 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4705 smob.h (scm_smobfuns),
4706 srcprop.c (prinsrcprops),
4708 unif.c, unif.h (scm_raprin1, rapr1),
4709 variable.c (prin_var): Changed argument `int writing' to
4710 `scm_print_state *pstate'.
4712 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4713 that it will be called before scm_init_print.
4715 * print.c (scm_prin1): Print states are now allocated when calling
4716 scm_prin1 and then passed around to all printing functions as an
4717 argument. A cache `print_state_pool' enables reuse of print
4719 (scm_make_print_state): New function.
4720 (scm_iprin1): Adaption to print states.
4721 (scm_iprlist): An initial "hare and tortoise" scan brings down
4722 time complexity to O (depth * N). (Better time complexity will be
4723 achieved when the printing code is completely rewritten.)
4725 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4727 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4728 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4729 it gets done whether or not the cache variable has a value.
4731 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4733 Distinguish #f and ().
4734 * __scm.h: #undef SICP.
4735 * pairs.h (SCM_EOL): Delete this definition, equating it with
4737 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4738 the value it used to have. Doc fixes, too.
4740 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4742 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4743 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4744 Lord's implementation of structs, allowing for tail arrays as
4745 described in the manual. Also fixed some bugs. (Both the interface
4746 and the implementation should be improved.)
4748 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4750 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4751 People who whish to see the source can do `(print-enable 'source)'.
4752 Removed #ifdef DEBUG_EXTENSIONS.
4754 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4756 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4757 integer (assuming for now accepting an integer is a good thing).
4759 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4760 %S will be used instead for write'ing arguments.
4762 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4763 asserts. fix a few other asserts.
4764 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4765 scm_uniform_vector_ref, scm_array_set_x,
4766 scm_dimensions_to_unform_array): change args in
4767 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4768 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4769 scm_substring_fill_x): likewise.
4770 gsubr.c (scm_gsubr_apply): likewise.
4771 eval.c (SCM_APPLY): likewise.
4773 * eval.c (4 places): replace scm_everr with lgh_error or
4776 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4777 scm_memory_error): new procedures.
4778 scm_everr: deleted. can use scm_wta, dropping first two args.
4779 scm_error: convert NULL subr to SCM_BOOL_F.
4781 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4784 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4787 * error.c, error.h: new error keys: scm_arg_type_key,
4788 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4790 scm_wta: reimplement using lgh_error instead of scm_everr.
4792 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4794 * gdbint.c: scm_lread now has one more argument.
4796 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4797 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4798 loading source from non-file ports, which, e. g., happens when
4799 using the Emacs interface).
4801 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4804 * read.c: Added code for recording of positions of source code
4805 expressions; New functions: recsexpr, scm_lreadrecparen;
4806 _scm_make_srcprops --> scm_make_srcprops
4807 (scm_flush_ws): Removed updating of positions counters. This work
4808 is already done by scm_gen_getc
4810 * read.h: Added prototype for scm_lreadrecparen
4812 * print.c: Added #include "alist.h"
4814 * eval.c: Added #include "hash.h"
4816 * eq.c: Added #include "ramap.h"
4818 * options.c: Documentation fixes.
4820 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
4821 (scm_init_srcprop): Adjusted size of initial source-whash. Name
4822 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
4823 --> scm_make_srcprops
4825 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
4826 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
4827 function calls in the definition of the whash access macros.
4829 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
4831 * init.c (scm_boot_guile): Add level of indirection to
4832 scm_boot_guile_1() to ensure that stack base pointer is properly
4833 initialized. There was no guarantee that variable i was the
4834 highest/lowest variable on stack (i.e. the call frame of
4835 scm_boot_guile was not completely protected from gc).
4837 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
4839 * ports.h (scm_port_table): put back file_name, it will be used to
4840 support debugging. Undo related changes in fports.c, ioext.c,
4843 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4845 * ports.h (scm_port_table): remove file_name member for now, it seems
4847 * fports.c (scm_open_file): don't set file_name in PTAB.
4848 (prinfport): don't use file_name in PTAB.
4849 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
4850 * ports.c (scm_add_to_port_table): don't intialize file_name.
4851 (scm_port_file_name): remove for now.
4852 * gc.c (scm_gc_mark): don't mark PTAB file_name.
4854 * fports.h (scm_mkfile): prototype deleted.
4855 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
4857 * debug.c, unif.c: use scm_out_of_range instead of
4858 wta for range errors (ASSERT still needs work).
4860 * error.c, error.h (scm_out_of_range): new procedure.
4862 * error.c, error.h (scm_out_of_range_key): new key.
4864 * posix.c (scm_sync): #else was missing.
4866 * error.c, error.h: append _key to names scm_num_overflow and
4869 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
4870 of consing an empty list.
4871 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
4872 of macros, saves code and string space.
4873 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
4874 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
4875 lower case. Rename scm_syserror_m to scm_syserror_msg.
4876 error.h: prototypes for new procedures.
4878 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
4880 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
4882 * error.c, error.h: setup scm_num_overflow key.
4884 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
4885 Remove definition of SCM_OVSCM_FLOW.
4887 * fports.c (scm_open_file): use SCM_SYSERROR_M.
4889 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
4890 explicit message and args.
4892 * error.c, error.h, __scm.h: change system_error_sym to
4895 * error.c (system_error_sym): remove leading %% from the Scheme name
4898 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
4900 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4902 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
4903 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
4904 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
4905 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
4906 renamed. (These were introduced by unsupervised name
4909 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4911 * print.c: Added code for detection of circular references during
4912 printing. (init_ref_stack, grow_ref_stack): New functions. Added
4913 a hook for printing of closures (accessible via print options).
4914 This leads to a split of calls to scm_iprin1 into two classes:
4915 elementary print operations (e. g. the code which prints a smob)
4916 still use scm_iprin1 while top level calls (like scm_display) use
4917 scm_prin1. scm_prin1 begins by clearing the data structure used
4918 to record reference information.
4920 * print.h: Added declarations of scm_prin1 and scm_prlist.
4922 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
4924 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
4926 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
4928 * error.c (err_head): scm_iprin1 --> scm_prin1
4930 * debug.c: Adjusted header comment.
4934 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4936 * strerror.c: Doc fix.
4938 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4940 * gdbint.c (gdb_read): Now possible to run during GC.
4941 (unmark_port, remark_port): New functions.
4943 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
4945 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
4946 of allocating a new string object. Also, increase size by
4947 the factor 2 instead of 1.5.
4949 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
4951 * __scm.h (SCM_P): Corrected to run under traditional C.
4953 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
4956 * async.c: Calls to scm_sysintern corrected.
4958 * async.h (scm_async_clock): Redundant declaration removed.
4960 * continuations.c (scm_dynthrow): Redundant declaration removed.
4962 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
4963 Definition typos corrected.
4965 * debug.h: Missing declarations of functions in debug.c added
4968 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
4969 Missing declarations to functions in eval.c added.
4971 * filesys.c: Possibly uninitialized variable rv.
4973 * gc.h (scm_object_addr, scm_unhash_name): Missing
4974 declarations of functions defined in gc.c added.
4976 * genio.c: Possible typos str_data -> wstr_data. ???
4978 * genio.c: Possibly unintended shadowing of local variable
4979 `int c' (gotos out of scope of inner `c'). ???
4981 * init.c: Uninitialized `SCM last' may be used.
4983 * ioext.h: (scm_sys_isatty_p): Typo.
4985 * list.h (scm_list_head): Missing prototype for function in
4988 * numbers.c (scm_two_doubles): Changed from extern to static
4989 (is used only within numbers.c).
4991 * numbers.h: Repeated declarations removed.
4993 * ports.h (scm_close_all_ports_except): Declaration for the
4994 function defined in ports.c added.
4996 * posix.h: Missing declarations added.
4998 * procs.h (scm_make_subr_opt): Missing declaration added.
5000 * socket.h (scm_sys_gethost): Missing declaration added.
5002 * socket.h: Redundant declarations removed (they are in fdsocket.h).
5004 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
5005 Missing declarations added.
5007 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
5009 * struct.c: Uninitialized variable `SCM answer' may be used.
5011 * unif.c (l2ra): Declaration prototype.
5013 * unif.c (scm_array_equal_p): Dummy definition removed (it is
5014 defined in ramap.c).
5016 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
5017 Redundant declarations removed (they are in ramap.h).
5019 * variable.h (scm_make_udvariable,
5020 scm_make_undefined_variable): Declaration corrected to
5021 correspond variable.c.
5023 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
5024 Missing declarations added.
5026 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5028 * Makefile.in (distclean): Don't forget to delete fd.h.
5030 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5032 * fd.h.in, tags.h: Trivial cleanups.
5034 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5035 marksweep.h just declared functions from gc.c.
5036 * gc.h, libguile.h: Don't #include "marksweep.h".
5037 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5038 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5039 dependencies updated.
5041 * libguile.h: Don't #include "files.h"; it's been deleted.
5043 * files.c (scm_sys_delete_file): Moved to filesys.c.
5044 File is now empty; deleted.
5046 * filesys.c: scm_sys_delete_file is now here. Remove
5047 #if's; they seem to rely on remnants of an old portability
5048 regimen. If the problems come up again, solve them properly,
5049 using autoconf. Specifically: Don't test M_SYSV, and #define
5050 remove to be unlink if it's #defined; don't use remove just
5051 because HAVE_STDC_HEADERS is #defined.
5052 * filesys.h: Add declarations for scm_sys_delete_file.
5053 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5054 files.o, files.h, files.c, and files.x.
5055 * init.c: Don't #include "files.h", and don't call scm_init_files.
5057 Use SCM_P instead of PROTO; the latter intrudes on the user's
5059 * params.h: Deleted; definition of SCM_P moved to...
5060 * __scm.h: ... here, where it replaces PROTO macro.
5061 * libguile.h, smob.h: Don't #include "params.h".
5062 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5063 smob.h: Fix prototypes accordingly.
5064 * Makefile.in: Update dependencies.
5065 (inner_h_files): Remove params.h.
5067 * gc.c: #include "gc.h"; every module should include its header,
5068 to let the compiler cross-check the declarations against the
5071 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5072 simpos.h: #include "libguile/__scm.h".
5074 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5076 * init.c: Don't forget to #include smob.h and init.h.
5077 * Makefile.in: Dependencies updated.
5079 * smob.h: Use PROTO instead of #if __STDC__.
5081 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5083 * __scm.h: Doc fixes.
5085 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5086 <angles>; this allows `make depends' to work properly.
5088 * libguile.h: #include smob.h and pairs.h before the others; they
5089 define typedefs used by other headers.
5091 C files should #include only the header files they need, not
5092 libguile.h (which #includes all the header files); the pointless
5093 recompilation was wasting my time.
5094 * Makefile.in (all .o dependency lists): Regenerated.
5095 * libguile.h: Don't try to get a definition for size_t here...
5096 * __scm.h: Do it here.
5097 * _scm.h: Since this is the internal libguile header, put things
5098 here that all (or a majority) of the libguile files will want.
5099 Don't #include <libguile.h> here; that generates dependencies on
5100 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5101 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5102 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5199 * weaks.c: Get "weaks.h".
5201 * stackchk.h: #include "libguile/debug.h",
5203 * print.h, read.h: #include "options.h", since everyone who uses
5204 either of these files will need that.
5206 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5207 anyone who uses this file will need them to define the smob
5208 printing functions. Also, get markers.h, since people will need
5209 to #define the mark functions.
5211 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5212 * ports.h: ... to here.
5214 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5215 don't rely on archaic C default type rules.
5217 * fports.h: #include "libguile/ports.h", since you need that in
5218 order to parse this.
5220 * genio.h: #include "libguile/print.h", because you need that to
5221 parse this; don't bother #including "ports.h", since print.h gets
5224 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5226 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5227 this; it's now a reference to an element of *scm_root.
5229 * debug.h: Don't #include "options.h"; the compiler won't be able
5230 to find that once the headers are installed; instead, #include
5231 "libguile/options.h".
5232 * gc.h: Same, with marksweep.h.
5233 * mbstrings.h: Same, with symbols.h.
5234 * scmhob.h: Same, with _scm.h.
5235 * smob.h: Same, with params.h.
5237 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5238 C files; there's no need for this, and it forces recompilations
5241 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5243 * error.c (scm_error): declare scm_error_callback.
5245 * error.h: prototype for scm_error_callback.
5247 * __scm.h: define lgh_error.
5248 (SCM_SYSERROR): redefine using lgh_error.
5250 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5252 * error.c (scm_error): new procedure.
5254 * error.h: prototype for scm_error.
5256 * Makefile.in (install): install scmconfig.h from the current
5257 directory, not $(srcdir).
5259 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5261 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,

5272 dependencies are within libguile properly.
5274 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5276 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5277 when scmconfig.h doesn't exist.
5279 * load.c (scm_sys_try_load): Correct spelling.
5281 * feature.c (scm_loc_features): Make this static.
5283 * Makefile.in (libpath.h): Omit trailing slash from path. We
5284 shouldn't require it of users, so why put it here?
5286 Move code to initialize and search %load-path from ice-9 to C
5287 code, so we can use the load-path to find the ice-9 boot code;
5288 this makes it easier to run Guile without installing it. See
5289 corresponding changes in guile/Makefile.in.
5290 * feature.c: Move stuff concerned with the load path to load.c.
5291 (scm_compiled_library_path): Deleted.
5292 Don't #include libpath.h here.
5293 * feature.h: Don't mention scm_compiled_library_path.
5294 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5295 <sys/stat.h>, and <unistd.h> (if present).
5296 (R_OK): #define if the system hasn't deigned to.
5297 (scm_loc_load_path): New variable.
5298 (scm_init_load_path, scm_sys_search_load_path,
5299 scm_sys_try_load_path): New functions.
5300 (scm_init_load): Initialize scm_loc_load_path to point to the
5301 value cell of the Scheme %load-path variable.
5302 * load.h: Add declarations for scm_sys_search_load_path,
5303 scm_sys_try_load_path.
5304 * init.c: Call scm_init_load_path.
5305 * Makefile.in (feature.o, load.o): Dependencies updated.
5307 * load.c, load.h: Rewrite using PROTO macro.
5309 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5311 * gc.c (scm_cellp): New function: C predicate to determine if an
5312 SCM value can be regarded as a pointer to a cell on the heap.
5314 * gc.h: Added declaration of scm_cellp.
5316 * gdb_interface.h: New file: The GDB interface header from the GDB
5319 * gdbint.c: New file: GDB interface.
5321 * gdbint.h: New file: GDB interface.
5323 * libguile.h: Added #include <libguile/gdbint.h>.
5325 * init.c (scm_boot_guile): Added scm_init_gdbint.
5327 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5328 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5329 found if object files and source are kept separate).
5331 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5333 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5335 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5337 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5338 TK_SRC_DIR; they're not relevant any more.
5340 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5341 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5343 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5345 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5346 search path, so we can find the <libguile/MUMBLE.h> headers.
5348 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5350 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5351 implicit in the .c.o rule.
5352 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5355 Put the library path in a header file, instead of passing it on
5356 the command line in every compilation.
5357 * Makefile.in (libpath.h): New target.
5358 (feature.o): Depend on libpath.h.
5359 (clean): Delete libpath.h.
5360 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5361 * feature.c: ... #include "libpath.h" here.
5362 * .cvsignore: Ignore libpath.h.
5364 Don't install the unwashed masses of Guile header files in the
5365 main #include path; put most of them in a subdirectory called
5366 'libguile'. This avoids naming conflicts between Guile header
5367 files and system header files (of which there were a few).
5368 * Makefile.in (pkgincludedir): Deleted.
5369 (innerincludedir): New variable; this and $(includedir) are enough.
5370 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5371 (installed_h_files): Divide this up. Now this variable lists
5372 those header files which should go into $(includedir) (i.e. appear
5373 directly in the #include path), and ...
5374 (inner_h_files): ... this new variable says which files appear in
5375 a subdirectory, and are referred to as <libguile/mumble.h>.
5376 (h_files): List them both.
5377 (install): Create innerincludedir, not pkgincludedir. Put
5378 the installed_h_files and inner_h_files in their proper places.
5379 (uninstall): Corresponding changes.
5380 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5381 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5382 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5383 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5384 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5385 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5386 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5387 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5388 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5389 vports.h, weaks.h: Find __scm.h in its new location.
5390 * __scm.h: Find scmconfig.h and tags.h in their new locations
5391 (they're both "inner" files).
5393 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5395 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5397 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5399 * posix.c: Doc fixes.
5401 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5403 * socket.c: Don't include a prototype for inet_aton; just use a
5404 K&R style declaration, to avoid warnings but minimize the chance
5405 of conflicts with the system.
5407 On NextStep, <utime.h> doesn't define struct utime, unless we
5408 #define _POSIX_SOURCE before #including it.
5409 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5410 * acconfig.h: New comment text for above CPP symbol.
5411 * configure.in: Call it.
5412 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5414 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5416 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5417 testing for __EMX__.
5419 * posix.c: #include <libc.h>, if it exists.
5421 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5422 don't even know if the latter exists.
5424 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5425 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5426 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5428 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5430 (scm_init_posix): Use them when initializing the Scheme constants
5433 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5435 * Makefile.in (libdir, includedir, bindir): Use the
5436 autoconf-supplied values, instead of deriving them ourselves.
5437 (pkgincludedir, datadir, pkgdatadir): New variables.
5438 (install, uninstall): Put the header files in a special
5439 subdirectory, not in the main search path.
5441 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5442 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5444 * Makefile.in (IMPLPATH): Deleted; never used.
5446 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5447 on the Tcl/Tk source any more.
5448 (INCLUDE_CFLAGS): Remove references to the above.
5450 * Makefile.in (version.o): Corrected dependencies.
5452 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5454 * libguile.h: #include "version.h"
5456 * init.c (scm_boot_guile): Call scm_init_version.
5457 * gscm.c (gscm_run_scm): Call scm_init_version.
5459 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5460 GUILE_VERSION): AC_DEFINE these.
5461 (acconfig.h): #undef the above symbols.
5463 * Makefile.in (libobjs): Add version.o.
5464 (installed_h_files): Add version.h.
5465 (c_files): Add version.c.
5466 (gen_c_files): Add version.x.
5467 (version.o): New rule.
5468 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5469 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
5470 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
5471 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
5472 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
5473 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
5474 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
5475 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
5476 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
5477 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5478 weaks.o): Add version.h to dependency lists.
5479 (markers.o): Remove duplicate rule.
5481 * version.h: New file.
5483 * version.c: New file.
5485 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5487 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5488 array; use it appropriately. Since GCC is quite happy to
5489 subscript functions, it never warned us about this; we should use
5490 -Wpointer-arith in the future. I guess we never tested
5493 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5495 * socket.c: Doc and copyright fixes.
5497 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5499 * debug.c: Fixed and improved gdb support.
5501 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5503 * socket.c: Added declaration of inet_aton to avoid compiler
5504 warning. (Hope this solution is correct.)
5506 * stime.c: Added declaration of ftime. (This is missing in
5509 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5511 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5513 * Makefile.in (c_files): add strerror.c.
5515 * strerror.c: new file from Emacs' sysdep.c.
5516 maybe configure should also check for sys_errlist.
5518 * configure.in (AC_REPLACE_FUNCS): add strerror.
5520 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5522 * debug.c (scm_init_debug): Added initialization for
5523 scm_evaluator_traps.
5525 * debug.h, debug.c: Various name changes.
5526 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5527 "debug-options-interface". See commentary in options.c.
5529 * options.h, options.c: Options now have documentation strings.
5530 Also added a long explanatory commentary.
5532 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5535 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5536 last_debug_info_frame is now updated in all cases.
5538 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5541 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5543 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5544 Added option STACK_CHECKING.
5546 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5548 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5550 * __scm.h: Removed symbols for debugging support.
5552 * acconfig.h: Added symbols for debugging support.
5554 * configure.in: Added user option for debugging support.
5555 --enable-debug will include the debugging code into libguile.a.
5557 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5558 scm_relocate_chunk_to_heap.
5560 * debug.c: New file: low-level debugging support. It also
5561 includes support for debugging with gdb. (The extensions to gdb
5562 are written by Per Bothner at Cygnus.)
5564 * debug.h: New file: low-level debugging support.
5566 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5567 argument pairs. Extensive modifications to the debugging
5568 evaluator. Added "SECTION:" commentaries to clarify what happens
5569 when, during double compilation. Renamed EVALIMP --> EVALIM.
5570 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5571 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5572 the beginning of the file. New procedure: scm_unmemocopy.
5573 Added some global state variables needed by the debugging
5574 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5575 check_entry, check_apply, check_exit, debug_options and
5576 evaluator_traps. New acro: undefine.
5578 * eval.h: Renamed EVAL --> XEVAL.
5580 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5581 --> scm_make_weak_key_hash_table.
5583 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5584 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5586 * libguile.h: Conditionally include debug.h
5588 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5589 scm_object_properties shouldn't return handle. `handle' now gets
5590 initialized in scm_set_object_properties_x. scm_object_properties
5591 doesn't any longer create an entry in scm_object_whash.
5593 * options.c: New file: handling of run time options.
5595 * options.h: New file: handling of run time options.
5597 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5599 * print.c: New procedure: scm_print_options
5601 * print.h: Defines for print options.
5603 * read.c: New procedure: scm_read_options
5605 * read.h: Defines for reader options.
5607 * root.h: Added scm_source_whash among scm_sys_protects.
5609 * srcprop.c: New file: source properties.
5611 * srcprop.h: New file: source properties.
5613 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5614 (Bug found by A. Green.)
5616 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5618 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5620 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5622 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5624 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5625 and should be called by the final client.
5627 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5629 * gc.h: Use the PROTO macro when declaring functions.
5630 * gc.c: Use the PROTO macro when declaring static functions.
5631 Remove the CPP hair around function definitions.
5633 * gc.c (scm_init_storage): Initialize scm_asyncs.
5635 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5636 preprocessor symbol; "__scm.h" is where it might get #defined.
5637 * __scm.h: Similar: #include <scmconfig.h> before testing
5640 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5642 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5644 * init.c (scm_boot_guile): Add init_func argument; call
5645 (*init_func) instead of calling scm_appinit; it's ucky to
5646 hard-code names for the user's procedures.
5647 * init.h (scm_boot_guile): Adjust declaration.
5649 * __scm.h (PROTO): New macro, for declaring functions with
5652 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5653 eliminate all the __STDC__ conditionals.
5654 (scm_boot_guile): Add declaration.
5655 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5656 Remove __STDC__ conditionals around function definitions; the
5657 declarations in init.h will provide the same information, more
5660 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5661 complain about it in the error message; the error message is
5662 adequate without that note, and there's nothing the user can do
5665 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5667 * Makefile.in (ancillary): Drop def.sed.
5669 * posix.c (scm_init_posix): Use numeric values, rather than
5670 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5671 F_OK. The symbols aren't available on some systems, and I'm
5672 pretty sure their values are fixed by common widespread practice.
5673 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5675 More functions unavailable on some systems.
5676 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5677 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5679 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5680 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5681 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5682 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5683 stub that signals an error as the #else.
5685 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
5687 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
5689 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
5691 * unif.c: include ramap.h.
5693 * read.c (endif): case_insensative_p renamed case_insensitive_p.
5695 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
5697 * ports.c: include sys/ioctl.h.
5699 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
5701 * configure.in: check for sys/ioctl.h.
5703 * ports.c: include <malloc.h> not "malloc.h".
5705 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5707 * fports.c: remove ttyname and tmpnam declarations.
5709 * posix.c: fewer ttyname declarations.
5711 * fports.c: include <string.h> not "string.h".
5713 * init.c, ioext.c: include string.h and unistd.h.
5715 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5717 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
5718 genio.c, simpos.c, vports.c: include string.h.
5720 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
5722 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
5724 (scm_addr_buffer_size): change type from scm_sizet to int.
5725 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
5726 from scm_sizet to int.
5728 * error.c: include unistd.h.
5730 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
5733 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
5735 * __scm.hd, def.sed: deleted.
5737 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
5739 Changes for NeXT, suggested by Robert Brown.
5740 * configure.in: Call AC_TYPE_MODE_T.
5741 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
5742 NeXT. Put header file list in alphabetical order.
5743 * configure, scmconfig.h.in: Regenerated.
5744 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
5746 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
5749 * acconfig.h: New file, providing documentation for the CPP
5750 symbols defined in configure.in
5751 * acconfig-1.5.h: Removed; superceded by the above.
5753 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
5755 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
5757 * fports.c (scm_open_file): don't return #f, throw error.
5759 * ioext.c (fileno): renamed from %fileno.
5760 (soft-fileno): deleted.
5762 * ports.c (scm_port_revealed): don't need to check for -1 from
5764 (scm_set_port_revealed_x): return unspecified, not #f.
5766 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
5768 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
5770 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
5772 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.

5776 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5777 This is necessary on Ultrix, and doesn't hurt portability.
5779 * Makefile.in (dist-dir): New target, implementing a new dist system.
5780 (installed_h_files): Put in alphabetical order.
5781 Remove duplicate entries for markers.h and unif.h.
5782 (c_files): Remove duplicate entries for markers.c.
5783 (ancillary): Renamed from anillery; all uses changed. Remove
5784 PLUGIN; it's a directory, and needs special treatment in dist-dir.
5785 Remove all the ../doc/* files; doc/Makefile.in handles that.
5787 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5789 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5790 every if must have an else, or else the whole command has a
5791 non-zero exit code whenever the if's condition is false.

5858 matter so long as it is non-0 (got rid of "* 4").
5860 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
5862 * gscm.h: gscm_mkarray eliminated (presumably was not being used
5863 since its definition was bogus).
5865 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
5867 * mallocs.[ch]: back again (for rx at least).
5869 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
5871 * ports.c: removed functions relating to the mapping between ports
5872 and descriptors. (That stuff is unix-specific and should be collected

5880 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
5881 handled correctly (SCM_FREEP was applied to them) -- test for
5882 NIMP. Keys in weak hash tables were spuriously (though harmlessly)

6050 initialization to fix a race condition.
6052 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

6076 set the multi_byte flag correctly in symbols. This is wrong.
6077 intern_obbary_soft and msymbolize should take an extra parameter.

6079 The weird symbol syntax is also a bit bogus (emacs doesn't quite
