1 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
3 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
4 and is now broken under NetBSD. I can't fathom what it's trying
5 to do, so I've replaced it with something that I do understand,
6 which seems to work, and which isn't broken on NetBSD. "Progress?
7 You Decide." (Thanks to Perry Metzger.)
9 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
10 signed/unsigned comparison.
12 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
14 Warning fixes from Greg Harvey:
15 * unif.c (scm_array_set_x): initializer for pos
16 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
17 * struct.c (scm_struct_ref, scm_struct_set_x): Added
18 initializers for field_type, since EGCS so desparately wants to
20 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
21 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
22 when GUILE_DEBUG is defined.
23 * dynwind.h (scm_wind_chain): Same.
24 * ports.h (scm_pt_size, scm_pt_member): Same.
25 * print.h (scm_current_pstate): Same.
26 * procs.h (scm_make_cclo): Same.
28 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
30 Handle short and long long uniform arrays properly. (Thanks to
32 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
33 raeql_1): Add cases for scm_tc7_svect (short vectors) and
34 scm_tc7_llvect (long long vectors).
36 Change the way libguile and boot-9.scm are timestamped, to try to
37 get rid of these spurious mismatch warnings. Now both
38 libguile/versiondat.h and ice-9/version.scm are generated directly
39 by the configuration process, rather than having version.scm
40 generated directly, and libguile/versiondat.h generated by the
41 Makefile, which is generated by configure. It seems that
42 sometimes the Makefile would change, but versiondat.h depends on
43 Makefile.in, not Makefile, so it wouldn't get rebuilt.
44 * Makefile.am (versiondat.h): Target removed; this is generated
45 directly by the configure script now.
46 (BUILT_SOURCES): Remove versiondat.h.
47 * versiondat.h.in: New file, transformed by the configure script
49 * Makefile.in: Regenerated.
51 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
52 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
53 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
54 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
55 if we want to use them in a header file some day, we can. (Thanks
58 * stime.c (scm_get_internal_real_time): Do the arithmetic using
59 SCM numbers, so we won't have rollover problems; the range of a
60 signed long in milliseconds is about 25 days. (Thanks to Karl
63 Don't redefine sleep and usleep; fix this problem now.
64 * coop.c (sleep, usleep): Remove declarations; we don't use or
65 redefine these any more.
66 (scm_thread_usleep, scm_thread_sleep): New functions which do the
67 job of usleep and sleep in a thread-friendly way. We can use
68 these in the rest of Guile. Define versions for systems both with
70 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
71 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
72 we're just using it, not redefining it, we can use a K&R style
74 (sleep): Declare this, too, if the system hasn't.
75 (scm_sleep, scm_usleep): Use scm_thread_sleep and
76 scm_uthread_sleep if they're available; otherwise, just call the
78 * scmconfig.h.in: Regenerated.
80 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
82 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
84 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
88 The argument type of usleep varies from system to system,
89 as does the return type. We really shouldn't be redefining usleep
90 at all, but I don't have time to clean that up before the 1.3.
91 release. It's on the schedule for afterwards. (Thanks to Julian
93 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
95 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
96 * scmconfig.h: Regenerated.
98 * simpos.c (scm_software_type): Procedure deleted. This isn't the
99 right way to handle system variation. Autoconf's approach is the
101 * simpos.h (scm_software_type): Declaration deleted.
103 * script.c (scm_find_executable): Don't test if unix is #defined
104 here; first, NetBSD doesn't #define it, and second, it's the wrong
105 way to go about these things. (Thanks to Perry Metzger.)
106 (dld_find_executable): Delete this MSDOS support code. This isn't
107 the way we want to support this; it needs to be rethunk at a
110 * genio.c (scm_do_read_line): Don't just politely check that the
111 line was either non-empty or EOF. Abort if it's empty and not
114 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
116 * scmconfig.h.in: Regenerated.
118 * libguile.h: Don't omit the dynamic linking functions. (Thanks
121 * genio.c (scm_do_read_line): Count lines correctly when the file
122 doesn't end in a newline.
124 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
126 * genio.c (scm_do_read_line): Maintain the line count correctly.
127 (Thanks to Harvey J. Stein and Greg Harvey.)
129 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
132 * numbers.c (big2str): Protect t from garbage collection until
133 we're done. (Thanks to Gary Houston.)
135 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
137 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
139 * Makefile.in: Regenerated.
141 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
142 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
145 Do magic to mix reads and writes on stdio FILE-based ports.
146 (Thanks to Christian Lynbech.)
147 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
149 (pre_read, pre_write): New functions.
150 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
151 local_fputs): Call them.
152 (local_fflush): Mark the port as ready for reading and writing.
153 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
154 flags on new port objects. This might not be accurate --- who
155 knows what state the FILE * is in when we get it --- but it won't
156 do extraneous calls to fflush or fseek, so it's no worse than the
157 behavior before this change.
158 * ports.h: Add comment.
160 Centralize the creation of port objects based on stdio FILE * in
161 fports.c; don't just throw them together anywhere.
162 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
163 what the rest of Guile wants. Don't set the revealed count;
164 that's only appropriate for stdin, stdout, stderr.
165 (scm_standard_stream_to_port): This function does set the revealed
167 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
168 not scm_stdio_to_port.
169 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
170 * fports.c (scm_open_file): Same.
171 * posix.c (scm_pipe): Same.
172 * socket.c (scm_sock_fd_to_port): Same.
173 * ioext.c (scm_fdopen): Same.
174 (scm_freopen): Moved from here to...
175 * fports.c (scm_freopen): ... here. This is really something that
176 munges the internals of an fport, so it should go here.
177 * fports.h (scm_stdio_to_port): Adjust prototype.
178 (scm_standard_stream_to_port, scm_freopen): New protoypes.
179 * ioext.h (scm_freopen): Prototype removed.
181 * filesys.c (set_element, get_element): This can work on both pipe
182 and file ports, so use SCM_FPORTP to typecheck, instead of testing
185 * scmconfig.h.in: Regenerated.
187 Change the definition of the functions in scm_ptobfuns so that
188 they get passed the port object, not the port's stream.
189 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
190 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
191 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
192 Pass the port itself to the scm_ptobs function.
193 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
194 scm_generic_fgets): Same.
195 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
196 getc_void_port, fgets_void_port, close_void_port): Just change the
197 argument names; these functions don't really do anything.
198 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
199 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
200 port as an argument, and use SCM_STREAM to get the stdio FILE *.
201 Also, use prototyped definitions, and get rid of the extra
203 (scm_fptob, scm_pipob): We don't need casts here any more.
204 * strports.c (prinstpt): Use prototype declarations.
205 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
206 and use SCM_STREAM to get the string info. Also, use prototyped
207 definitions, and get rid of the extra declarations.
208 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
211 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
212 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
214 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
215 scm_fgets, for consistency.
216 (scm_fptop, scm_pipob): References updated.
218 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
220 Include the source location in error messages for scripts.
221 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
222 stack is still there when we catch the error.
223 * throw.c (handler_message): If we are handling an error with a
224 message, then put together the proper arguments and call
225 scm_display_error, instead of scm_display_error_message. That
226 displays source location, if it can find it.
228 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
230 * gc.c (scm_unprotect_object): Change this so that calls to
231 scm_protect_object and scm_unprotect_object nest properly.
232 (scm_protect_object): Doc fixes.
234 * strings.c (scm_string_set_x): Require the argument to be a
235 writable string, not a substring or a symbol.
236 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
237 (Thanks to John Redford and Charbel Jacquin.)
239 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
241 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
243 * eval.c (safe_setjmp): Remove this misunderstanding.
244 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
247 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
249 * libguile.h: Mark these as C declarations, for compilation by C++
252 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
253 __cplusplus clause. I seriously doubt this ever worked the way
254 the author seems to have intended.
256 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
258 Utterly needless cleanups to hopelessly messy code.
259 * ports.c: Doc fixes.
260 (scm_fflush): Moved to ...
261 * genio.c (scm_fflush): ... here, amongst all the other port
262 method invocation functions.
263 * genio.h, ports.h: The prototype moves too.
265 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
267 * backtrace.c (display_error_body): The current frame does not
268 always have a parent frame; consider a function called directly
269 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
272 * alloca.c (alloca): Undo yesterday's changes, and simply call
273 malloc directly for storage, and abort if we don't get what we
274 want. The situation is much simpler --- just call malloc. Emacs
275 has bizarre/evil requirements (signal handlers might malloc unless
276 you set this global flag, so you have to set the flag around all
277 calls to malloc) which we are certainly not going to conform to,
278 so we can do the simple and obvious thing.
280 * coop.c (coop_condition_variable_wait): Make this function
281 static. It's only useful internally --- you should never just
282 wait on a condition variable.
283 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
285 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
287 * unif.c (scm_array_set_x): Accept any kind of number as an
288 element for a uniform vector of doubles. This is more consistent
289 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
291 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
292 works; I can't conveniently test it myself. (Thanks to Dvid
293 Tillman for the bug report.)
297 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
298 from here, not from scm_compile_shell_switches (which is a pretty
299 dumb place to do it).
300 (scm_load_startup_files): New function.
301 (scm_ice_9_already_loaded): Variable moved to here from script.c.
302 * script.c (scm_compile_shell_switches): Don't load the startup
304 (scm_ice_9_already_loaded): Variable moved.
305 * init.c (scm_load_startup_files): Prototype for new function.
306 * gh_init.c (gh_enter): Doc fix.
308 1998-10-03 <jimb@savonarola.red-bean.com>
310 Some anti-warning changes from Greg Harvey.
311 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
312 warnings when it doesn't understand our NORETURN declarations in
314 * posix.c (scm_mknod): Similar.
316 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
318 * posix.c (scm_getpwuid): If we can't find an entry, return our
319 own message, instead of using scm_syserror --- the getpwMUMBLE
320 functions don't set `errno' to anything interesting.
322 1998-10-03 <jimb@savonarola.red-bean.com>
324 Get rid of warnings from the cooperative threading system.
325 * threads.h (scm_single_thread_p, scm_yield,
326 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
327 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
328 scm_wait_condition_variable, scm_signal_condition_variable): Add
329 prototypes for these Scheme-visible functions.
330 * coop-defs.h (coop_next_runnable_thread,
331 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
332 Prototypes for these here, even though they're from iselect.c.
333 (coop_condition_variable_wait, coop_join): Add prototypes.
334 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
335 scm_threads_free_condvar): Make these smob functions static.
336 * coop-threads.h (coop_init): Give this a real prototype.
337 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
338 (coop_next_runnable_thread): No need to provide prototype; it's in
341 * scmconfig.h.in: .detarenegeR
343 * iselect.c, threads.c: Doc fixes.
345 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
347 * Makefile.in: Regenerated with a patched automake, to get
348 dependency generation right when using EGCS.
350 * inet_aton.c (inet_aton): Add prototype, to remove compiler
351 warning. (Thanks to Robert Pluim.)
353 * inet_aton.c (inet_aton): Reassure the compiler that the
354 arguments to the <ctype.h> macros are all unsigned characters, not
357 1998-10-03 <jimb@savonarola.red-bean.com>
359 Getting rid of more warnings...
360 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
361 today's change to ../configure.in.
362 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
363 * scmconfig.h.in: Regenertaded.de.,.__
364 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
365 (scm_localtime, scm_mktime): Use a const char * to manipulate the
368 * readline.c: Doc fix.
369 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
370 * readline.h (scm_filename_completion_function): Add prototype.
371 (scm_init_readline): Make this into a prototype.
373 * readline.c (scm_filename_completion_function): Use SCM_PROC to
374 declare this, instead of calling scm_make_subr manually.
376 1998-10-02 <jimb@savonarola.red-bean.com>
378 * readline.h (scm_init_readline): Add prototype for this.
379 (scm_init_readline): Make this a real prototype.
381 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
383 Warning fixes from Maciej Stachowiak:
384 * backtrace.h (scm_display_application, scm_backtrace): Add
386 * debug.c (scm_m_start_stack): Make this function static.
387 * fluids.h (scm_fluid_p): Add prototype.
388 * procprop.c (scm_i_procedure_arity): Make this function static.
389 * regex-posix.c (scm_regexp_error_msg): Make this function static.
390 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
391 * root.h (scm_dynamic_root): Add external prototype.
392 * scmsigs.h (scm_usleep): Add external prototype.
393 * script.h (scm_init_script): Use prototype, not K&R decl.
394 * stacks.h (scm_stack_id): Add external prototype.
395 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
397 1998-09-30 Mark Galassi <rosalia@cygnus.com>
399 * gh.h: took out the definitions of vset and vref, since they are
400 replaced by the proper vector routines that correspond to the R4RS
403 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
405 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
406 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
407 third argument, a C expression that should result in a SCM value,
408 which is used to initialize the variable. Reimplemented
409 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
412 * version.h (scm_libguile_config_stamp): Add prototype.
413 (From Maciej Stachowiak.)
415 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
417 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
418 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
420 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
422 * print.c (scm_iprin1): Rather than having one i, and using it in
423 several places, declare a fresh i local to each block where it is
424 used, and give it a signedness appropriate to its use in each case.
427 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
430 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
431 signed/unsigned clashes.
433 * posix.h (scm_tmpnam): Added prototype.
435 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
436 scm_make_subclass_object): Add external prototypes.
438 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
439 comparison is okay here.
441 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
443 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
444 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
446 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
449 * load.c (swap_port): Make this function static.
451 * load.c (scm_search_path): Make max_path_len and max_ext_len
452 unsigned, since they're compared against string sizes.
454 * load.c (init_build_info): Make i unsigned.
456 * ioext.h (scm_read_line): Add prototype.
458 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
459 scm_hash_fn_remove_x): Make hash bucket index local variable k
460 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
461 accurately as possible.
463 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
464 comparisons, and range checking to make sure those casts are
467 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
468 signed/unsigned comparisons.
470 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
471 avoid signed/unsigned comparisons.
472 * smob.h (scm_numsmob): Change extern declaration to match.
474 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
475 avoid signed/unsigned comparisons.
476 * ports.h (scm_numptob): Change extern declaration to match.
477 (scm_current_load_port, scm_set_port_line_x,
478 scm_set_port_column_x): New prototypes.
480 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
481 test code, and it causes warnings.
483 * gh.h (gh_int2scmb, gh_uniform_vector_length,
484 gh_uniform_vector_ref): Added prototypes.
486 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
487 debugging support unconditionally. That's backtrace.c, stack.c,
488 debug.c, and srcprop.c.
489 (EXTRA_libguile_la_SOURCES): Omit those from here.
490 * Makefile.in: Regenerated.
492 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
494 * options.c (scm_options): Bugfix: Allow empty list of options!
496 * debug.c, debug.h (scm_single_step): Removed.
497 (scm_with_traps): New procedure. This procedure could easily be
498 written in Scheme but needs to be highly optimized.
500 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
502 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
503 Check SCM_TRAPS_P before trapping.
505 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
507 Changes to avoid signed/unsigned comparison warnings.
508 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
509 (scm_gc_sweep): Make n and j local to the blocks they're used in,
510 so they can have appropriate types for each application. Make i
511 signed. Use initializers in some spots. I'll probably pay for
513 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
514 (scm_must_realloc): Make nm unsigned.
515 (init_heap_seg): Make new_seg_index and n_new_objects signed.
516 (scm_init_storage): Use prototype-style definition, and make the
518 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
519 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
521 * filesys.c (scm_readlink): Make local vars rv and size ints, to
522 avoid signed/unsigned comparison warnings, and because the return
523 value of readlink may be -1. Don't bother casting the third
524 argument to readlink.
526 * filesys.c (scm_dirname, scm_basename): Move these to their own
527 page, at the end of the file.
528 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
530 * eval.h (scm_eval_options_interface): Add external prototype for this.
531 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
533 * eval.c (scm_lookupcar1): Make this static.
535 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
536 Make these prototype declarations, not K&R-style.
538 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
539 unsigned comparison warning.
541 * appinit.c: File removed. It had a single function in it, empty,
542 whose reason for existence is explained in no documentation or
543 comment. I think it's there as a default for some Tcl-style
544 initialization, but Tcl abandoned that approach a while ago.
545 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
546 (BUILT_SOURCES): Remove appinit.x.
547 * Makefile.in: Regenerated.
549 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
551 * Makefile.in: Regenerated using the last public version of
552 automake, not the hacked Cygnus version.
554 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
556 Remove Totoro kludge.
557 * Makefile.in, scmconfig.h.in: Regenerated.
558 * init.c, readline.c: Don't check if TOTORO is #defined.
560 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
562 * Makefile.am: Adjust for new thread configuration system.
563 (INCLUDES): Include the value of THREAD_CPPFLAGS.
564 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
566 (THREAD_LIBS): Definition deleted; automake will generate such
567 things automatically.
568 * Makefile.in: Regenerated.
570 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
572 Simplify smob and port marking; set the mark bit in the generic
573 marking code, and make marker routines only responsible for
574 turning up outgoing pointers.
575 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
576 before calling the marking function. Don't call the marking
577 function if it's zero.
578 * markers.c (scm_mark0): Just return #f. This function isn't
579 necessary at all now, but it's harmless to call it. We'll leave
580 it in so other folks' code doesn't croak at link time.
581 (scm_markcdr): Don't call SCM_SETGC8MARK.
582 * async.c (mark_async): Don't call SCM_SETGC8MARK.
583 * dynl.c (mark_dynl_obj): Same.
584 * root.c (mark_root): Same.
585 * srcprop.c (marksrcprops): Same.
586 * unif.c (markra): Same.
587 * variable.c (scm_markvar): Same.
588 * ports.c (scm_markstream): Same.
589 (void_port_ptob): Specify zero for our marking function.
590 * debug.c (debugobjsmob): Same.
591 * dynwind.c (guardsmob): Same.
592 * filesys.c (dir_smob): Same.
593 * fluids.c (fluid_smob): Same.
594 * fports.c (scm_fptob, scm_pipob): Same.
595 * mallocs.c (mallocsmob): Same.
596 * regex-posix.c (regex_t_smob): Same.
597 * smob.c (freecell, flob, bigob): Same.
598 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
599 * throw.c (jbsmob, lazy_catch_funs): Same.
601 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
603 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
604 scm_copy_tree on code in order not to let memoized code to leak
605 out. Thus, scm_copy_tree needs to copy vectors as well since
606 quasiquote can introduce evaluated code also inside vector
609 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
611 * eval.c (scm_copy_tree): Removed ability to copy vectors.
613 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
614 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
617 * unif.c: Say that ivect and uvect are of type signed and unsigned
618 long instead of int in commentary so that it correctly describes
621 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
623 * stime.c: Removed declaration of strptime. (It should be
624 declared by the system headers. If it turns out that some systems
625 don't, we'll handle that then.) (Thanks to Greg Troxel.)
627 * stime.h: Renamed TIMEH --> STIMEH
629 * backtrace.c (scm_display_error, scm_display_backtrace): In order
630 to increase portability, don't use structure assignment.
631 (Thanks to Nicolas Neuss.)
633 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
635 (finalize_fd_sets): Added empty statement after last case label.
636 (Thanks to Nicolas Neuss.)
638 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
641 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
643 * init.c, readline.c: OK, I won't have these readline.x bug
644 reports anymore. We've had them since April. The current reason
645 is a completely unintelligible failure of totoro.red-bean.com to
646 do the test for rl_getc_function in libreadline correctly. This
647 kludge overrides the test if we're on totoro so that the snapshot
648 generation process can work.
650 * readline.c: Define a strdup replacement if not existent on system.
652 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
654 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
655 This change makes scm_make_vector R5RS compatible. We cannot keep
656 the third argument since people want to be able to deduce the form
657 of the C function call only by looking at R5RS. (At the same time
658 we have removed some unnecessary complexity!)
660 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
661 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
662 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
663 argument in call to scm_make_vector.
665 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
667 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
668 This macro is useful in applications.
670 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
672 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
673 (scm_parse_path, scm_search_path): New Scheme level procedures.
675 * load.h (scm_internal_parse_path, scm_parse_path,
676 scm_search_path): Declared.
678 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
680 * filesys.c (dirname, basename): New procedures.
682 * init.c (scm_boot_guile_1): Removed condition around
685 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
686 new data type (guards) for representation of C level guards and
687 data on the wind chain.
688 (scm_internal_dynamic_wind): New function.
690 * dynwind.h: Declare scm_internal_dynamic_wind.
692 * root.h (scm_root_state): Added scm_cur_loadp.
694 * root.c (mark_root): Added comment about cur_loadp.
696 * load.c: #include "dynwind.h";
697 (scm_primitive_load): Use scm_inner_dynamic_wind to update
700 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
702 * ports.c (current-load-port): New procedure.
704 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
706 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
707 not a tty, return #f.
709 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
710 to Julian Satchell and Roland Kaufmann.)
712 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
713 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
715 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
717 * debug.h, debug.c (scm_start_stack): New function. Implements
718 the guts of old scm_m_start_stack.
720 * debug.c (scm_m_start_stack): Use scm_start_stack.
722 * init.c (scm_start_stack, scm_restart_stack): Renamed to
723 start_stack and restart_stack. (These have static scope.)
725 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
727 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
728 readline functions to come in release 2.3. (Thanks to Chet
730 (handle_errors): Use the above functions.
732 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
734 * readline.c: Improvements for readline support: Handle errors
735 better; Implement before-read-hook.
737 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
739 * init.c (scm_boot_guile_1), readline.c: Test for
740 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
741 assure that we have version >= 2.1.)
743 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
745 * readline.c (scm_readline): Defer interrupts while we're calling
748 * readline.c (scm_add_history): Bugfix: Do strdup before giving
749 away the string to add_history.
750 (completion_function): Do completion for readline. (Thanks to
752 (scm_filename_completion_function): New procedure: Filename
754 (current_input_getc): New function. Use this one instead of
755 standard getc from readline.
757 * throw.c, throw.h (scm_handle_by_throw): New function: This
758 handler throws errors to next handler on the dynwind chain.
760 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
762 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
765 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
767 * procprop.c (scm_i_procedure_arity): New function. Returns arity
769 (scm_procedure_properties): Modified to return arity together with
771 (scm_procedure_property): Added the read-only property `arity'.
772 (scm_set_procedure_property_x): It is an error to set the `arity'
775 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
776 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
778 * procprop.h (scm_sym_arity): New symbol.
780 * objects.c (scm_set_object_procedure_x): New procedure: Use this
781 to set the dispatch procedure of an operator or entity object.
783 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
784 Made procedure slots read-only.
786 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
787 scm_tcs_cons_gloc case in zero args switch; Fixed args
788 construction for operators in scm_tcs_cons_gloc case in two args
791 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
793 * fluids.c: Removed use of assert.h (in order to avoid
796 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
798 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
800 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
801 change makes the evaluator safer at the cost of evaluation speed.
802 It handles the case when the user has added a non-immediate
803 improper end of the application form, e.g., `(+ 0 . x)'.
804 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
805 minimize the extra cost as much as possible. The new code is
806 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
807 problem with structs planted directly in the code (e.g. by a
808 macro). This no longer causes segmentation fault. (Thanks to
811 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
812 arg `proc' in order to be able to throw errors; New argument
815 * Removed extra #include "debug.h"
817 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
819 * scmsigs.c: Declare usleep as returning void on some systems.
820 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
823 * coop.c (usleep): Return void on some systems.
825 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
827 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
829 * coop.c: Changed return type of usleep to int.
831 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
832 isn't found in the OS.
834 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
835 isn't enabled. (Thought that I had made this change ages ago...)
837 * iselect.c: Declare bzero if not defined by OS.
839 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
841 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
842 condition. (Thanks to John Tobey.)
844 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
845 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
848 * __scm.h: Start the long-term project of moving to POSIX threads.
849 Phase 1: Classification of all critical sections.
850 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
851 for A sections. (See comments in __scm.h for details.)
853 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
854 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
856 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
858 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
859 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
860 (libpath.h, versiondat.h): Replaced dependency on Makefile with
861 dependencies on $(srcdir)/Makefile.in
862 $(top_builddir)/config.status in order to avoid circularity.
864 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
865 from argc if argc was 0 initially.
867 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
868 in generation of libpath.h.
870 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
872 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
873 libguile from 2 to 3.
875 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
877 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
879 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
881 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
882 scm_set_port_column_x, scm_port_filename,
883 scm_set_port_filename_x): Removed optional arguments. Added
884 proper argument checking.
886 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
887 stack size in machine words.
889 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
890 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
891 to Ole Myren Röhne.)
893 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
895 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
896 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
898 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
901 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
902 procedure apply: Copy argument lists before pushing them unto the
903 environment so that the environment won't get mutated due to
904 manipulation of procedure arguments. This should perhaps be
905 regarded as a temporary solution until someone finds a more
906 efficient one. (Thanks to Maciej Stachowiak.)
908 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
910 * script.c (scm_compile_shell_switches): Use "guile" as default
911 zero arg if argc is NULL.
913 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
915 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
916 is zero. (Thanks to Dirk Herrmann.)
918 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
920 * ports.c (scm_add_to_port_table): First line is now line 0
921 (was 1). (Interface changed according to suggestion by Per
924 * backtrace.c (display_header): Add 1 to line and column numbers
925 when presenting them to the user.
927 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
928 from debug.c --> eval.c
930 * eval.h, eval.c (scm_eval_options_interface): New options
932 (SCM_EVAL_STACK): New option: Size of newly created stacks,
933 i.e. stacks for new threads.
935 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
937 * eval.c (unsafe_setjmp): Removed with #if 0.
939 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
942 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
943 to avoid compiler warnings.
945 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
947 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
949 * throw.c (handler_message): Print message on current error port
950 instead of default error port. (Thanks to Maciej Stachowiak.)
952 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
954 * ports.c (scm_add_to_port_table): allocate in units of
955 struct scm_port_table *, not struct scm_port_table.
956 * posix.c (scm_close_pipe): remove the port from the port table
958 Thanks to Rob Engle for both fixes.
960 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
962 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
963 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
965 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
967 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
969 * backtrace.c (display_error_body, display_backtrace_body),
970 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
971 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
972 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
973 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
976 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
977 don't receive the jmpbuf arg anylonger.
978 (scm_catch): Don't accept a #f tag.
979 (scm_throw): Check that key is a symbol.
980 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
982 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
984 * async.c (async_pending): Removed declaration.
986 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
988 * dynwind.c (scm_wind_chain): New debug function.
990 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
991 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
992 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
993 extra layer of functions around the body and handler of a thread.
994 This extra layer makes sure that the handler is called in the
995 dynamic context of the surround (= empty dynwind list), but under
996 the *dynamic root* of the body. We can not use the dynamic root
997 of the surround since that root belongs to another thread => stack
998 is not handled correctly. It may seem ugly to use this extra
999 layer, but the extra cost in terms of execution time is really
1000 negligible compared to the total amount of time required to create
1001 a thread, and it would reduce maintainability to duplicate the
1002 crucial and complicated steps performed by cwdr.
1004 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
1005 (SCM_ALLOW_INTS): Added thread switching code before interrupts
1006 get re-enabled. The important effect of this is that interrupts
1007 are blocked during thread switching so that thread data structures
1008 don't risk getting messed up by an unfortunate signal.
1009 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
1010 seems to do more aggressive optimization which actually move
1011 instructions around in these macros in a fatal way. Therefore:
1012 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
1013 just superstitious...)
1014 (SCM_TICK): Maybe do a context switch and take care of asyncs.
1015 This macro should be used instead of SCM_ASYNC_TICK since the
1016 latter doesn't do context switches any more.
1018 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
1019 instead of SCM_ASYNC_TICK.
1021 * coop.c, iselect.c: Since thread switches are now performed with
1022 interrupts masked, we can't use the old mechanism of delivering
1023 signals immediately when they arrive. Signals must instead be
1024 delivered when the asyncs run *after* the end of the critical
1025 section in scm_internal_select. But this also means after context
1026 switch so that the signal will be delivered to a different thread.
1027 To avoid this, I have changed the protocol of
1028 coop_wait_for_runnable_thread and friends so that they are allowed
1029 to return the original thread. So, if a signal arrives during
1030 scm_internal_select, we won't any longer be forced do a context
1031 switch, but can remain in the same thread and deliver the signal
1034 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
1035 scm_asyncs_pending and made it global.
1037 * iselect.c: Small fixes.
1039 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
1040 coop_condition_variable_init, coop_condition_variable_wait,
1041 coop_condition_variable_signal): Changed return type from `void'
1042 to `int'. This is to adhere closer to the pthreads interface.
1043 This, in turn, is part of an attempt to provide C versions of the
1044 mutex and condition variable primitives which can be part of a
1045 frontend to COOP or pthreads.
1047 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
1048 coop_condition_variable_destroy): New functions.
1050 * coop-threads.c (scm_wait_condition_variable): Use
1051 coop_condition_variable_wait_mutex.
1053 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
1054 Definitions moved to coop-defs.h.
1056 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
1057 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
1058 scm_cond_destroy): New C interface to mutecis and cond vars.
1060 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1062 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
1064 * iselect.c: Now several threads can wait on the same file
1065 descriptor. The behaviour is compatible with OS select: All
1066 threads waiting for the fd return with the same status.
1068 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1070 * coop-threads.c, threads.h (scm_spawn_thread): New function.
1071 Can spawn a thread from application C code.
1073 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1075 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
1076 gh_doubles2scm): New functions.
1078 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
1080 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
1081 commented-out version of gh_eval_str()
1083 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
1085 * socket.c (scm_bind): free soka after use.
1087 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
1089 * stime.c (tzvar): new variable.
1090 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
1091 avoid memory leaks when allocating.
1093 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
1095 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
1098 * gc.c, tags.h: Doc fixes.
1100 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1102 * eval.c (macro-eval!): Removed. This function was a design bug.
1103 It allowed memoized code to leak out to the scheme level. Most
1104 things that you could do with `macro-eval!' can be done with
1107 1997-12-20 Tim Pierce <twp@skepsis.com>
1109 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
1110 scm_fgets now depends on ftell(3) to know how many bytes were
1113 1997-12-15 Tim Pierce <twp@skepsis.com>
1115 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
1116 dealing with strings.
1118 1997-12-13 Tim Pierce <twp@skepsis.com>
1120 Make %read-line more suitable for implementing read-line efficiently.
1121 * ioext.c (scm_read_line): Strip the terminating newline from a
1122 string, and return a cons of the string and its terminator.
1124 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
1125 of the string that is read is stored in this memory location.
1126 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
1127 * genio.c, genio.h (scm_do_read_line): Update caller.
1128 * ports.h (scm_ptobfuns): Update typedef.
1129 * fports.c (scm_fptob, scm_pipob): Update struct.
1131 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1133 * filesys.c (set_element): Return file descriptor.
1134 (fill_select_type): Return the highest file descriptor.
1135 (scm_select): Tell select about the highest file descriptor. On
1136 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
1137 Therefore the extra overhead for calculating the maximum fd seems
1138 to be more than compensated. Is this correct? In any case,
1139 scm_internal_select will be much faster with this info.
1140 (scm_select, fill_select_type, set_element): Don't accept any kind
1141 of object in the file descriptor list or vector.
1143 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1145 * iselect.c (finalize_fd_sets): Bugfix.
1147 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1149 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1150 when using scm_internal_select (since we might switch to another
1153 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1155 * simpos.c (scm_system): always define: use sysmissing if not
1156 available. Check for HAVE_SYSTEM instead of _Windows (does
1157 Windows lack system or does it have an unusable one?).
1158 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1159 Let the argument be optional: if not supplied, call system(NULL).
1161 * ports.c (scm_close_port): relax the type check from OPPORTP to
1162 PORTP; closing a closed port is allowed.
1164 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1166 * fports.c (scm_fgets): Return if the last char in a chunk is
1167 newline. When fgets returns a string whose length is `size-1', it
1168 is ambiguous whether a whole line was retrieved, so we must check
1169 explicitly whether a line terminator is present.
1171 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1173 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
1174 before taking the CDR. (Thanks to Harald Meland.)
1176 * filesys.c (scm_stat): Slightly optimized.
1178 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
1180 * ports.c (scm_close_port): Make sure the port is open before
1183 * guile-snarf.in: Pass args through to gcc in a way that preserves
1184 whitespace boundaries. (Thanks to Greg Badros.)
1186 1997-12-02 Tim Pierce <twp@skepsis.com>
1188 * stacks.c (scm_frame_procedure): Reverse the logic in the return
1189 statement. (Thanks to Doug Evans for pointing this out.)
1191 1997-12-01 Tim Pierce <twp@skepsis.com>
1193 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
1195 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
1197 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
1198 errno macro expansion of this field name. (errno is a C
1199 preprocessor macro on some systems.)
1201 1997-11-29 Tim Pierce <twp@skepsis.com>
1203 * iselect.c: Doc fix.
1205 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
1207 * init.c (scm_start_stack): Removed initialization of
1208 scm_the_last_stack_var.
1210 * backtrace.h: Declare scm_the_last_stack_var.
1212 * backtrace.c: Define scm_the_last_stack_var.
1214 * root.c (mark_root): Don't mark the_last_stack_var.
1216 * root.h (scm_root_state): Removed the_last_stack_var.
1218 * throw.c: Added #include "fluids.h"
1219 (ss_handler): `the-last-stack' is now a fluid.
1221 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
1222 --> the_last_stack_fluid.
1224 * backtrace.c: Added #include "fluids.h"
1225 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
1226 (scm_backtrace): `the-last-stack' is now a fluid.
1228 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
1229 after scm_init_fluids.
1231 1997-11-28 Tim Pierce <twp@skepsis.com>
1233 * iselect.c: #ifdef USE_THREADS around thread-related includes.
1235 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
1236 DLSYM_ADDS_USCORE to decide whether to add an underscore.
1238 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1240 * iselect.c (coop_next_runnable_thread,
1241 coop_wait_for_runnable_thread): Disable interrupts so that no
1242 async is executed before a potential error_revive.
1243 (scm_internal_select): Disable interrupts during the parts of the
1244 code which manipulate the sleep queue and the file descriptors.
1246 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1248 * Makefile.am: Added iselect.c and iselect.h.
1250 * coop.c (coop_qinit): Initialize fields used by
1251 scm_internal_select.
1252 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1253 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1254 replacement in iselect.c.
1255 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1256 coop_join): If GUILE_ISELECT enabled, use
1257 coop_wait_for_runnable_thread instead of
1258 coop_next_runnable_thread.
1259 (usleep, sleep): New replacements for system functions if
1260 GUILE_ISELECT is enabled.
1262 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1264 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1266 * filesys.c: Added #include "iselect.h". Moved FD-macros to
1267 iselect.h. Implement Scheme level `select' using
1268 scm_internal_select. (See NEWS.)
1270 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1272 * init.c: Call scm_init_iselect.
1274 * iselect.h, iselect.c: New files. Implements
1275 scm_internal_select. (See NEWS.)
1277 1997-11-27 Tim Pierce <twp@skepsis.com>
1279 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1280 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1281 and scm_must_free, since ultimately the string returned will be copied
1282 by scm_makfrom0str anyway. Also, read any characters that may have
1283 been pushed onto the port with scm_ungetc.
1284 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1285 * ioext.c (scm_read_line): Free string after Guilifying it.
1286 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
1288 1997-11-26 Anthony Green <green@hoser.cygnus.com>
1290 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
1292 * gh.h: Safely wrap prototypes for c++ usage.
1294 1997-11-25 Mark Galassi <rosalia@cygnus.com>
1296 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
1297 gh_repl (argc, argv).
1299 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1301 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1302 and to invoke scm_shell().
1303 (gh_launch_pad): took out the loading of boot-9.scm from here,
1304 since it is probably best to let the user control that. In fact,
1305 gh_repl() now invokes scm_shell() which does that.
1307 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1309 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()

1315 yesterday's underscore patch. (Thanks to Marius Vollmer for
1318 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
1320 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
1321 DLSYM_ADDS_USCORE is not defined.
1323 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
1325 * gh_data.c (gh_uniform_vector_length):
1326 (gh_uniform_vector_ref): started implementing the uniform types in
1329 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
1331 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1332 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1334 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1336 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1337 configure.in was changed).
1339 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
1341 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1342 * Makefile.in: Regenerated.
1344 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1346 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1347 OPORT is an `open' port, not an output port.
1349 * filesys.c (scm_close, set_element, get_element, scm_chown,
1350 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
1351 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
1352 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
1353 scm_close_port, scm_port_line, scm_set_port_line_x,
1354 scm_port_column, scm_set_port_column_x, scm_port_filename,
1355 scm_set_port_filename_x, scm_port_mode,
1356 scm_close_all_ports_except, scm_set_current_output_port,
1357 scm_set_current_error_port): Likewise
1358 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1359 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
1361 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
1362 * backtrace.c (display_backtrace_body): Likewise
1363 * fports (scm_setvbuf): Likewise
1364 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
1365 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
1366 scm_getpeername, scm_send, scm_sendto): Likewise
1367 * unif.c (scm_uniform_array_write): Likewise
1369 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
1371 Minor problems with substring-related tag changes.
1372 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1373 exactly what we want to leave in to detect substrings.
1374 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1375 * tags.h: Fix diagrams and comments describing the S tag bit;
1376 remove vestigial remarks about the D tag bit.
1377 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
1378 * strings.c: Formatting tweaks.
1380 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1381 variable first; then SCHEME_LOAD_PATH, with a warning message.
1382 (scm_parse_path): New function.
1383 * script.c: Doc fixes.
1385 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1387 Readline support, from Daniel Risacher.
1388 * readline.c, readline.h: New files.
1389 * init.c: #include "readline.h".
1390 (scm_boot_guile_1): Call scm_init_readline, if we have it.
1391 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1392 * Makefile.in: Regenerated.
1393 * scmconfig.h.in: Regenerated, after change to ../configure.
1395 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1397 * gh.h: gh_vector_set -> gh_vector_set_x
1399 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1401 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1402 with the ! -> _x mapping when going from Scheme to C.
1404 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1406 * gh.h (gh_reverse):
1414 (gh_assoc): added these gh_ functions implemented as macros.

1417 (gh_string_equal_p): added these two missing predicates.
1419 * gh_list.c (gh_append):
1424 (gh_set_cdr_x): added these routines as I go through and try to
1425 complete the picture R4RS functions that should be mirrored in the
1428 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1430 * tags.h (scm_tc7_substring): Changed the comment and code to
1431 conform with the changes below. Folks! We have suddenly two new
1432 free tc7 codes!!! Jummy, jummy!
1434 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
1436 * Makefile.in: Rebuilt.
1437 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
1439 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.

1462 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
1463 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
1465 Don't include "mbstrings.h".
1466 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
1467 (SCM_SYMBOL_SLOTS): Define as 4.
1468 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.

1489 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
1490 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
1492 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1494 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1496 * gh_test_c.c (c_vector_test): some improvements on the vector
1499 * gh.h (gh_vector): this used to exist but do the wrong thing.
1500 Now it (almost) does the right thing, though it takes a list
1501 instead of the individual arguments. I need to see how it could
1503 (gh_list_to_vector): added this function as a macro. Corresponds
1504 to Scheme's (list->vector ...).
1505 (gh_vector_to_list): added this function as a macro. Corresponds
1506 to Scheme's (vector->list ...).
1508 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1509 gh_vector_ref, so that it resembles the Scheme routines more.
1510 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1511 resembles the Scheme routines more.
1512 (gh_make_vector): this used to be (stupidly) called gh_vector().
1513 This is the right name, since it does the same thing as the Scheme
1514 (make-vector ...) procedure.
1516 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1518 * ports.h: #include "libguile/print.h"

1521 Some indentation fixes.
1523 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
1524 longer a user field; New field: class_flags.

1528 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
1530 * gh_data.c (gh_bool2scm): new function which replaces
1531 gh_int2scmb(), which is now tagged as obsolete.
1533 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1535 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1536 macros should by convention not test for NIMPness.)
1537 (SCM_COERCE_OPORT): Adjust indentation.
1539 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1540 SCM_NIMP test before SCM_PRINT_STATE_P.
1542 * struct.c, struct.h, gc.c: Renamed:
1543 scm_struct_i_layout --> scm_vtable_index_layout
1544 scm_struct_i_vcell --> scm_vtable_index_vcell
1545 scm_struct_i_vtable --> scm_vtable_index_vtable
1546 scm_struct_i_printer --> scm_vtable_index_printer
1547 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1549 * struct.c (scm_print_struct): Use new printer slot; Default
1550 printing: Also output hex code of vtable so that type identity
1551 will be indicated as well.
1552 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1553 Removed struct_printer_var; Removed struct-vtable-offset;
1554 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1555 vtable-offset-user): New constants.
1557 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
1558 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
1559 If this slot contains a procedure, use that to print structures of
1560 the type represented by this vtable.
1562 * print.c (scm_iprin1): Don't print arguments of macro
1563 transformers. (They are always: exp env.); Bugfix: Unmemoize
1564 transformer source with correct environment.
1566 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1568 Streamlining of call-with-dynamic-root:
1570 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
1571 there is now only one catch.
1572 (cwdr_outer_body): Removed.
1573 (cwdr_handler): New function.
1574 (scm_internal_cwdr): New function to perform the function of cwdr
1575 but take args that are more useful to C code. Also, the handler
1576 is now invoked *outside* of the new dynamic root, like the docs
1577 say. We no longer have to catch absolutely all errors, the caller
1578 is responsible for using a handler that does not throw, if he
1580 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1581 * root.h (scm_internal_cwdr): New prototype.
1583 Even more but risky streamlining:
1585 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1586 allocation of the jumpbuf of a root continuation. The changes
1587 below are controlled by it. They are now deactivated.
1588 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1589 the JMPBUF of the scm_rootcont to NULL before returning.
1591 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1592 when they are non-NULL.
1593 (scm_gc_mark): Likewise, mark only when non-NULL.
1595 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1596 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1598 * gc.c (scm_done_malloc): New function.
1599 gc.h (scm_done_malloc): New prototype.
1601 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
1602 (struct scm_print_state) [revealed]: New field.
1603 (scm_print_state_vtable): Make visible to the outside world for
1604 type checking purposes.
1605 (scm_valid_oport_value_p): New prototype.
1607 * print.c (scm_valid_oport_value_p): New function to check whether
1608 a certain value is acceptable as a port argument.
1609 (scm_print_state_vtable): New variable.
1610 (scm_free_print_state): Set `revealed' field to false.
1611 (scm_iprin1): Call user supplied closure printer with
1612 scm_printer_apply. Print in the traditional way when there isn't
1613 one or when it returns #f.
1614 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1615 Accept a port/print-state pair in addition to just a port.
1616 (scm_prin1): Don't return the print_state to the pool when it has
1618 (scm_printer_apply): Set `revealed' field of print_state to true.
1619 (scm_init_print): Set scm_print_state_vtable.
1620 (print_state_fluid, print_state_fluid_num): Removed.
1622 * throw.h (scm_handle_by_proc_catching_all): New prototype
1623 throw.c (scm_handle_by_proc_catching_all): New function
1625 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1627 * Makefile.in: Regenerated with automake 1.2c.
1629 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1631 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1632 was looping endlessly.
1634 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1636 * strports.c (scm_eval_string): Don't close the port.
1638 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1639 former returns a nice normal integer. (Thanks to Daniel
1642 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1644 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1645 makefile variable as a build parameter called LIBS. The
1646 build-guile program will use this, for the time being.
1647 * Makefile.in: Regenerated.
1649 Thanks to Shiro Kawai:
1650 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1651 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1654 * Makefile.in: Regenerated with automake 1.2a.
1656 * script.c (scm_compile_shell_switches): If we hit the -c or --
1657 arguments, don't set the car of (command-line) to scm_usage_name,
1658 the prettified name of the guile executable; give it the full
1659 path, the way shells usually handle $0.
1661 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1663 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1664 Scheme-level name `array-map' and renamed `serial-array-map' to
1665 `serial-array-map!'.
1667 * backtrace.c: Introduced exception handlers which now enclose
1668 `display-error' and `display-backtrace' so that error reporting
1669 won't get into infinite loops if an error occurs during displaying
1670 of the error. This can very easily happen with user supplied
1671 print call-back routines.
1673 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1675 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1676 the names `serial-array-map' and `array-map' should be removed.)
1678 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1680 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1681 Added #include "objects.h"
1683 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1684 Add #include "feature.h".
1686 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1687 (modinclude_HEADERS): Added objects.h.
1689 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1690 This test is needed at many places in the code and should be
1691 abstracted. (Motivated by the need of this test in libguiletk.)
1693 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1694 (scm_eval_string), load.c (scm_primitive_load,
1695 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1696 Use SCM_EOF_OBJECT_P.
1698 * eval.c (scm_init_eval): Add feature `delay'.
1700 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1702 * scmhob.h: Removed.
1704 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1706 * list.h (SCM_LISTn): New macros. Make list creation in C code
1707 prettier. The idea comes from STk.
1709 * sequences.h, sequences.c, append.h, append.c: Removed. These
1710 files implemented non-R4RS operations which would encourage
1711 non-portable programming style and less easy-to-read code.
1713 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1716 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1717 sequences.h, #include append.h.
1719 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1722 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1724 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1726 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1728 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1730 * eval.c: Added #include "objects.h"
1732 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1735 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1736 adjacent smob numbers.
1738 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1740 * procprop.h: Added declaration of scm_i_inner_name.
1742 * gsubr.c: New global symbol scm_i_inner_name.
1744 * debug.c (scm_procedure_name): Try procedure property
1745 `inner-name' if `name' fails.
1747 * print.c (scm_iprin1): Use scm_macro_name.
1749 * eval.c (scm_m_define): Give names to macros as well; Only the
1750 first top-level definition gives a procedure/macro a name.
1751 Otherwise confusing names can turn up in backtraces.
1752 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1753 `name'; Give names to macros as well.
1755 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1756 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1759 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1761 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
1763 (prinmacro): Removed. The code has been moved/merged into print.c
1764 in order to decrease code redundancy. We want macros to print in
1765 a way equivalent to procedures, and it would be silly to duplicate
1766 the required code. (We don't want to maintain two places.)
1767 (macrosmob): Print field is now a NULL pointer.
1769 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1770 scm_macro_transformer): New prototypes.
1771 (scm_tc16_macro): Declared.
1773 * * print.c (scm_iprin1): Added code for printing of macros. Macros
1774 are now printed in a way equivalent to procedures.
1776 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1778 * procs.h (scm_closure_p): Added declaration.
1780 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1782 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
1783 Shouldn't pass "heap" as the subr name.
1785 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1787 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
1788 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
1789 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1790 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1791 SCM_BOOL_T. Any non-false value is true.
1793 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1795 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1796 scm_gensym): Added prototypes.
1798 * symbols.c (scm_gensym): New function. This will speed up
1799 certain types of applications (such as macro systems) which
1800 generate lots of symbols.
1802 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1804 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
1806 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
1808 * unif.c (scm_shap2ra): tighten the checking of the array dimension
1809 specifier, since (2) or (2 . 3) would cause SEGV.
1810 (scm_transpose_array): more argument checking fixes.
1812 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1814 * Makefile.in: Regenerated.
1816 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1818 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
1820 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1822 * error.c, error.h (scm_error_callback): Removed (see NEWS).
1824 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
1826 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
1827 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
1830 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
1831 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1832 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
1833 scm_array_p, scm_array_rank, scm_array_dimensions,
1834 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
1835 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
1836 scm_array_prototype): Added case scm_tc7_wvect.
1838 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
1840 * errno.h: prototype for scm_strerror.
1841 * error.c (scm_strerror): new procedure.
1843 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1845 * list.c (scm_list_append_x): Allow non-pair as last argument.
1846 This is consistent with the R4RS append and is probably the
1847 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1849 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1851 * stime.h: prototype for scm_times.
1852 * stime.c (scm_times): new procedure.
1853 * ioext.c (scm_fseek): if the first argument is a file descriptor
1855 (scm_ftell): if the first argument is a file descriptor call lseek
1857 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
1858 * filesys.c (scm_chmod): if the first argument is a file descriptor,
1860 (scm_chown): if the first argument is a port or file descriptor,
1862 (scm_truncate_file): new procedure.
1863 Add DEFER/ALLOW INTS to a few other procedures.
1864 (scm_fsync): new procedure.
1865 (scm_open_fdes): new procedure.
1866 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
1868 (scm_fcntl): the first argument can now be a file descriptor. The
1869 third argument is now optional.
1871 * posix.c (scm_execl, scm_execlp): make the filename argument
1872 compulsory, since omitting it causes SEGV.
1873 (scm_sync): return unspecified instead of #f.
1874 (scm_execle): new procedure.
1875 (environ_list_to_c): new procedure.
1876 (scm_environ): use environ_list_to_c. disable interrupts.
1877 (scm_convert_exec_args): take pos and subr arguments and
1878 improve error checking.
1880 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1882 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1883 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1884 argument to SCM_ASSERT. Furthermore, the name of the function
1885 should be passed as first argument when signalling
1886 SCM_WNA. (Thanks to Thomas Morgan)
1888 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1889 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1890 dispatches on the number of actual args has a default case
1891 reporting an internal error. This is a vestige from a version
1892 that mallocated a SCM vector to hold the arguments. In the
1893 current version this check is too late: if it ever happens we will
1894 have already overstepped the bounds of the array.
1896 Also, the patch [...] adds a check for too many actual arguments."
1898 mdj: Removed check for "internal programming error".
1900 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1902 * gh_io.c (gh_write): New function.
1904 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
1905 throw.c (scm_internal_stack_catch): New sibling to the other catch
1906 functions. Code moved from gh_eval.c.
1907 throw.h: Added header.
1908 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
1909 scm_internal_stack_catch.
1911 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1913 * ioext.h: fix up prototypes.
1914 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
1915 Scheme name is now dup->fdes.
1916 (scm_dup_to_fdes): make the second argument optional and
1917 fold in the functionality of scm_primitive_dup.
1918 (scm_primitive_dup): deleted.
1920 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1922 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
1923 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
1924 ultrix are defined. Use setvbuf instead of setbuf.
1925 (scm_setvbuf): new procedure.
1926 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
1927 (scm_setfileno): moved from ioext.c.
1928 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
1929 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
1931 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1933 * fluids.c (scm_fluid_p): New function.
1934 * fluids.h (scm_fluid_p): New prototype.
1936 Sat Jul 26 21:33:37 1997 Marius Vollmer <mvo@zagadka.ping.de>
1938 * print.c (scm_iprin1): Enter printed structures into the print
1939 state as nested data while they are printed.
1940 (print_state_fluid, print_state_fluid_num): New variables.
1941 (scm_init_print): Initialize them.
1942 (scm_iprin): If print_state_fluid carries a print_state, use that
1943 instead of creating a new one.
1944 (scm_printer_apply, apply_stub, struct apply_data): New
1945 definitions to help with calling printer functions written in
1947 * print.h (scm_printer_apply): New prototype.
1949 * struct.c (scm_print_struct): Use scm_printer_apply to call the
1950 user defined struct printer.
1952 * dynwind.c (scm_dowinds): Handle fluids on the wind list.
1953 * fluids.h (scm_internal_with_fluids, scm_with_fluids,
1954 scm_swap_fluids, scm_swap_fluids_reverse): New prototypes.
1955 * fluids.c (scm_internal_with_fluids, scm_with_fluids,
1956 scm_swap_fluids, scm_swap_fluids_reverse): New functions.
1958 Fri Jul 25 12:05:46 1997 Marius Vollmer <mvo@zagadka.ping.de>
1960 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
1961 SCM_ASSERT: arg comes before pos.
1963 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1965 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
1966 to a list of length zero correctly.
1968 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1970 Supply an `fgets' method for port objects to do fast line i/o.
1971 * ioext.c (scm_read_line): New function.
1972 * genio.c (scm_gen_read_line): New function.
1973 * fports.c (scm_fgets): New function.
1974 (scm_fptob, scm_pipob): Add scm_fgets method.

1980 * strports.c (scm_stptob): Supply generic fgets method.
1982 Mon Jul 21 04:03:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1984 * ioext.h: removed scm_duplicate_port prototype.
1986 * ioext.c (scm_primitive_dup2): return the new file descriptor
1987 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
1989 (scm_fdopen): bug fix: don't try to make port unbuffered until its
1990 stream has been set.
1991 (scm_duplicate_port): deleted, there's now an implementation in
1993 (scm_primitive_dup2): do nothing if newfd == oldfd.
1995 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
1997 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
2000 * ioext.h: new prototypes.
2001 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
2003 * fluids.c (next_fluid_num): don't do
2004 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
2006 * ports.h: prototypes too.
2007 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
2009 * fports.h: prototype too.
2010 * fports.c (scm_evict_ports): moved from ioext.c.
2012 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2014 * ports.c (scm_close_port): return a boolean instead of unspecified.
2015 throw an error if an error other than EBADF occurs.
2017 * filesys.h: scm_close prototype.
2018 * filesys.c (scm_close): new procedure, can close file descriptors
2019 and ports (scsh compatible).
2021 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
2024 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
2026 * fluids.c, fluid.h: New files.
2027 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
2028 (modinclude_HEADERS): Added "fluids.h"
2030 * init.c: Include "fluids.h". (scm_boot_guile_1): Added call to
2031 scm_init_fluids to initialize the fluid machine.
2032 (scm_start_stack): Initialize the fluids of the first root with
2033 scm_make_initial_fluids.
2035 * root.h: Added "fluids" member to scm_root_state.
2036 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
2037 (scm_make_root): Call scm_copy_fluids to make fluid bindings
2038 unique for the new root when it has a parent.
2040 * smob.h: Include "libguile/print.h" to make scm_print_state
2043 * dynl.c (free_dynl_obj): New function to free the dynamic object
2044 data. (dynl_smob): Use it.
2045 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
2046 the dynamic object data below the linking of the object to avoid
2047 memory leak when the linking code throws an error. Now the code
2048 leaks a whole dynamically linked library when must_malloc throws,
2049 but that should be much less likely.
2051 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
2053 Changes to compile under gnu-win32, from Marcus Daniels:
2054 * stime.c (tzset): If tzset isn't provided, make it a NOP.
2055 (scm_localtime): Change SCM_EOF to SCM_EOL.
2056 (scm_mktime): Likewise.
2057 * socket.c: Don't include sys/un.h unless autoconf tells
2058 us Unix domain sockets are available.
2059 (scm_fill_sockaddr): Ignore Unix domain code.
2060 (scm_addr_vector): Likewise.
2061 (scm_init_addr_buffer): Likewise.
2062 (scm_socketpair): Don't include unless socketpair was
2063 found during autoconf.
2064 * simpos.c (SYSTNAME): Treat cygwin like Unix.
2065 * scmsigs.c (scm_pause): Don't include unless pause was found
2067 * posix.c (scm_getgroups): Don't include unless support function
2068 was found during autoconf (in this case, getgroups).
2069 (scm_setpwent): For setpwent.
2070 (scm_setegid): For setegid.
2071 * net_db.c (scm_inet_netof): Don't include unless support
2072 function was found during autoconf (in this case, inet_netof).
2073 (scm_lnaof): For inet_lnaof.
2074 (scm_inet_makeaddr): For inet_makeaddr.

2086 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
2087 scm_misc_error, not SCM_EOF.
2089 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
2090 arguments for formatting the error message, not SCM_BOOL_F. I
2091 think this is left over from the (eq? '() #f) days.
2093 * read.c (recsexpr): Give this a dummy definition if
2094 DEBUG_EXTENSIONS isn't #defined.
2096 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
2098 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
2101 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>
2103 * root.c (cwdr_outer_body): Bugfix: Pass `c' instead of `&c' to
2106 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
2108 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
2109 alloca.lo will be included in @LIBLOBJS@. Something better than
2110 this should be possible.
2111 * Makefile.in: Regenerated.
2113 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2115 * simpos.h: prototype for scm_primitive_exit.
2116 * simpos.c (scm_primitive_exit): new procedure, terminates the
2117 process without unwinding the stack.
2119 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
2121 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
2122 argument and logior its components together, so the user doesn't
2123 have to do this explicitly. Also, if regexp/basic is supplied, then
2124 turn off REG_EXTENDED.
2125 (scm_init_regex_posix): New regexp/basic symbol.
2126 (REG_BASIC): #define this if it is not already present.
2128 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2130 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
2131 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
2132 (CLEANFILES): New target, clean versiondat.h, libpath.h.
2133 (DISTCLEANFILES): New target, clean *.x.
2134 * Makefile.in: Regenerated.

2139 years in usage message.
2141 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
2142 * Makefile.in: Regenerated.
2144 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
2145 flag; I don't think we support it.
2146 (scm_make_regexp): Make sure the user doesn't pass the
2149 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
2151 (scm_init_regex_posix): Define constants for the REG_mumble flags;
2152 name them according to the SCSH convention: regexp/mumble.
2154 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
2156 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
2158 * Makefile.am (libpath.h): Include the values of all the standard
2159 Makefile directory variables. Print a message, but don't print
2161 (versiondat.h): Print a message, but don't print all the commands.
2162 * load.c: #include "alist.h".
2163 (init_build_info): New function.
2164 (scm_init_load): Call it.
2165 * Makefile.in: Regenerated.
2167 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
2169 * root.c: Establish a reliable catch-all handler for the new root.
2170 After all the Scheme handler function might signal an error too,
2171 and we don't want to lose that.
2172 (cwdr_inner_body): Renamed from cwdr_body.
2173 (cwdr_outer_body): New function, to establish the user's handler,
2174 and pass control to cwdr_inner_body.
2175 (cwdr): Establish the reliable catch-all handler here, and pass
2176 control to cwdr_outer_body.
2177 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
2178 the user's handler through to cwdr_outer_body.
2179 * throw.c (scm_handle_by_message): Move guts into....
2180 (handler_message): New static function.
2181 (scm_handle_by_message_noexit): New function.
2182 * throw.h (scm_handle_by_message_noexit): New prototype.
2184 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
2185 across this. Only works on GCC. Otherwise, we hope for the best.
2186 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2187 the feeling that real thread systems will not need this...
2189 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2191 Try to detect when people are using one version of libguile and a
2192 different version of ice-9. People have been skewing things and
2193 sending in bug reports.
2194 * Makefile.am (versiondat.h): New file to generate.
2195 * version.c: #include "versiondat.h", to get version info.
2196 (scm_libguile_config_stamp): New function.
2197 * script.c: #include "version.h".
2198 (scm_compile_switches): Call scm_version to get version number.
2199 * scmconfig.h.in, Makefile.in: Regenerated.
2200 * Makefile.in: Regenerated.
2202 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
2203 primitive definitions under their Scheme names.
2205 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2206 1:2. Helps avoid confusion between installed and uninstalled libs.
2208 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2211 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2212 backslash from definition; this should be used like: GDB_INTERFACE;
2214 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2216 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
2217 new port unbuffered until its stream has been set.
2219 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2221 * ports.h: new prototype.
2222 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
2224 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
2226 Make things compile neatly under Sun's C compiler.
2227 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
2228 * extchrs.c (xmbtowc): Make the second arg a normal char, not
2229 unsigned, because that's what the ANSI function takes.
2230 * extchrs.h (xmbtowc): Corresponding change to prototype.
2231 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2233 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2234 argument plain char *.
2235 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2237 * tag.c (scm_tag): Remove unreachable statement.
2238 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2239 top of the word, it should be unsigned.
2241 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2242 is defined, to avoid warnings; it's only used in the
2243 conflict-checking code. Which might go away anyway.
2244 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2245 conditionals; put the label definition in an #if too, to stifle
2248 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2249 ChangeLog-threads in the distribution.
2250 * Makefile.in: Regenerated.
2252 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2254 * guile-snarf.in: Changed regexp to support CPPs that insert
2255 whitespace between lexical tokens (which munges the `%%%' snarf
2258 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2260 * load.c (scm_init_load_path): Append $(datadir)/guile to
2261 %load-path, so modules do not have to be installed in Guile's
2262 current version directory.
2264 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2266 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2267 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2268 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2269 call the sysdep functions with deferred ints.
2270 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2271 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2272 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2275 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2278 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2280 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2282 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2284 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2287 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2289 * eval.c (scm_lookupcar1): New procedure to cope with a race
2290 condition during lookup (when using threads).
2291 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2292 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2295 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2297 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2298 supplied. (Change from Tim Pierce.)
2300 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2302 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2303 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2304 default and not `()'. `#f' is the canonical non-value in Scheme,
2307 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2309 * struct.c (struct_printer): New variable that holds a handle on
2310 the Scheme variable *struct-printer*. This variable can be set by
2311 Scheme code to override the printing of structures.
2312 (scm_print_struct): If struct_printer is set, call it. If it is
2313 not set, or returns #f, print the structure in the old fashion.
2314 Include "eval.h" for scm_apply.
2316 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2318 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2319 scm_struct_i_n_words to get the number of fields, not
2320 -scm_struct_n_extra_words.
2322 On the route to fancier struct printing:
2323 * struct.c (scm_print_struct): New function to print a structure.
2324 Include "genio.h" to support it. This function doesn't do
2325 anything interesting right now, but I think it should be here
2327 * struct.h: Include "print.h" and add prototype for
2329 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2330 print structures ourself.
2332 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2334 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2335 before applying the handler in case it doesn't return.
2337 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2339 * scmsigs.h, async.h: updated.
2341 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2344 * posix.c (scm_uname): interpret only negative values as an error.
2345 Solaris normally returns a positive value.
2347 * script.c (scm_compile_shell_switches): if we are not going into
2348 an interactive repl, set scm_mask_ints to zero so that asyncs can
2351 * simpos.c (scm_system): don't ignore/unignore signals around
2354 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2357 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2358 done in boot-9.scm instead.
2360 * scmsigs.c, async.c: Major rewriting of signal handling code.
2361 (scm_sigaction): new procedure.
2362 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2364 (scm_raise): return unspecified, throw error on failure.
2366 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2368 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2369 feature, to help boot-9.scm decide whether to import the regex
2372 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2374 * eval.c: Include scmconfig.h at the beginning of the file so that
2375 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2378 * regex-posix.c: #include "_scm.h" before conditionally #including
2379 <regex.h>; the former defines HAVE_REGCOMP.
2381 * regex-posix.c: #include <regex.h> conditionally, so the file is
2382 CPP'able (for dependency scanning) even on systems that don't have
2385 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2387 Add new R4RS-compliant syntax for keywords.
2388 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2389 regardless of the setting of the `keywords' read option.
2390 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2391 can be re-read no matter what the setting of the `keywords' read
2394 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2396 Add support for POSIX regular expressions.
2398 * regex-posix.c, regex-posix.h: New files. (Some code
2399 is taken liberally from rx/rgx.c in the old Guile dist.)
2401 * init.c: Include regex-posix.h.
2402 (scm_boot_guile_1): Call scm_init_regex_posix.
2404 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2405 Add regex-posix.[ch] sources.
2406 * Makefile.in: Regenerated.
2408 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2409 to do this automatically? It didn't for me, bleh.)
2411 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2413 * fports.c (print_pipe_port): New function.
2414 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2415 latter doesn't even take the right arguments.
2417 * Makefile.am: Increment shared lib revision number. I think
2418 sometimes the uninstalled Guile finds the installed shared lib;
2419 Gord says doing this might help. As things turned out, I can't
2420 say whether it does.
2421 * Makefile.in: Regenerated.
2423 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2424 passing it as the closure argument to scm_boot_guile. (Bill
2427 * ports.c (print_void_port, putc_void_port, puts_void_port,
2428 write_void_port, flush_void_port, getc_void_port, close_void_port,
2429 noop0): Use ANSI prototypes instead of K&R declarations, so the
2430 initialization of void_port_ptob gets aggressively type-checked.
2431 Fix arguments of print_void_port and write_void_port. (Bill

2465 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2467 * script.c (scm_find_executable): Use prototype-style definition
2468 here; apparently it's not quite right to have const in a prototype
2469 and then use a K&R declaration. I wonder if stuff like this will
2470 go away if we compile with -Wrequire-prototypes, or whatever that
2471 is... (Bernard URBAN)
2473 * scmhob.h: New text from Bernard URBAN.
2475 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2477 * script.c: Don't #define const on hpux. Configure takes care of
2478 this. (Thanks to Larry Schwimmer.)
2480 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2481 decide whether to #include <unistd.h>, instead of listing a bunch
2482 of systems. Don't #include stdio twice. Removed dyked-out
2483 definition of scm_find_impl_file.
2485 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2487 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2488 library version info to 1:0.
2489 * Makefile.in: Regenerated.
2491 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,
2492 gdb_interface.h, gdbint.c, gdbint.h, gh_data.c, gh_init.c,
2493 gh_io.c, gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c,

2495 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2496 throw.c: Update copyright years; these files have been worked on
2497 significantly in 1997, but only had copyright years for 1996.
2498 Also, change name of copyright holder on some from Mikael
2499 Djurfeldt to Free Software Foundation; he has signed papers
2500 assigning the changes to the FSF.
2502 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2503 reason not to give the user the option.
2505 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2506 Return #f on end-of-file when scanning table (i.e. when called
2507 with no arguments). Try to catch errors, when we can.
2508 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2510 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2511 external declarations. These are useful.
2513 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2515 * posix.c: don't include <sys/select.h> or define macros for
2516 select, since they were not used in this file.
2518 * filesys.c (scm_select): make the fifth parameter microseconds,
2519 not milliseconds. let the fourth parameter be either a real value
2520 or an integer or #f. The first, second and third arguments can
2521 now be vectors: the type of the corresponding return set will be
2523 (set_element, get_element): new static procedures.
2525 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2527 * strports.c (scm_eval_string): New function.
2528 (scm_eval_0str): Trivially re-implemented in terms of
2530 * strports.h (scm_eval_string): New extern decl.
2532 * net_db.c (h_errno): Add extern decl for this.
2534 * fports.c (local_pclose): New function.
2535 (scm_pipob): Use it in the initializer here.
2538 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2539 Use a meaningful error message when signalling an error. For
2540 this, scm_gethost must check h_errno rather than errno.
2542 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2544 * Makefile.in: Regenerated, using automake-1.1p.
2546 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2548 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2549 not SCM_UNSPECIFIED.
2551 * script.c (scm_compile_shell_switches): don't append (quit) if
2553 (scm_shell): call scm_exit_status and exit on the result of the
2556 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2558 Ensure that shared substrings are handled properly when passed to
2559 a system call or other foreign function. Many thanks to Tim
2561 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2562 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2563 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2564 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
2565 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
2566 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
2567 (scm_display_error_message): use RO macros when strings may be RO.
2568 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
2569 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
2570 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
2571 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
2572 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
2573 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
2574 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
2575 scm_strftime), vports.c (scm_make_soft_port): use
2576 SCM_COERCE_SUBSTR to make sure shared substrings are
2579 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2581 * error.c (scm_error): Add newline to error message.
2583 * init.c (scm_init_standard_ports): Doc fix.
2585 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2587 * dynl-shl.c: Completely replaced with new code from Bernard
2590 * script.c (scm_ice_9_already_loaded): New variable.
2591 (scm_compile_shell_switches): Use it.
2593 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2595 * filesys.c (scm_input_waiting_p): add missing third argument to
2598 * stime.c (scm_localtime): copy the result of localtime before
2599 calling gmtime in case they share a buffer.
2600 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2603 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2605 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2607 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2609 * Makefile.am (check-local): New target, which causes 'make check'
2610 to run gh_test_c and gh_test_repl, with some trivial input.
2611 * Makefile.in: Rgnrtd.
2613 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2615 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2618 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2620 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2621 sure how this was supposed to work.
2622 (scm_async_click): don't send SCM_TICK_SIGNAL.
2623 (scm_init_async): don't initialize %tick-thunk.
2625 * the following change doesn't affect the Scheme interface:
2626 gc-thunk is called at the end of garbage collection. however it's
2627 no longer implemented by pretending it's a signal.
2629 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2630 system async corresponding to scm_gc_thunk.
2631 * async.h: declare scm_gc_async.
2632 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2633 gc-thunk directly, instead of going through a signal handler.
2634 (scm_gc_async): new variable, points to the GC system-async.
2635 (scm_init_async): save the GC async as scm_gc_async instead
2636 of using system_signal_asyncs.
2637 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2639 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2641 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2642 Don't screw up if we're interrupted.
2643 * Makefile.in: Regeneradet.
2645 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2647 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2649 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2650 we're not using AM_INIT_GUILE_MODULE any more.
2651 * Makefile.in: Reneregated.
2653 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2655 Functions for finding variable bindings, grace à Tim Pierce.
2656 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2657 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2659 Get 'make dist' to work again.
2660 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2661 * Makefile.in: Regenerated, like a surry without a fringe on top.
2663 Changes for reduced Guile distribution: one configure script,
2665 * configure.in, configure: Removed.
2666 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2667 real configure script lives.
2668 * Makefile.in, scmconfig.h.in: Regenerated.
2670 * init.c: #include "script.h", to get prototype for script.c's
2673 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2675 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2676 scm_must_malloc, not raw malloc.
2678 * script.c (scm_compile_shell_switches): Dyke out debugging output
2681 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2683 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2685 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2686 system has them. Hope this is safe. Previously
2687 sys/timeb.h was included if HAVE_FTIME was defined or if
2688 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2689 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2691 * ioext.c (scm_setfileno): add missing third argument to
2692 scm_misc_error call.
2694 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2696 * eq.c (scm_equal_p): Correctly compare strings of different
2697 varieties. (Thanks to Tim Pierce.)
2699 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2701 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2702 #! block comment must occur on a line all by itself.
2704 Move most of the guts of shell command processing into libguile,
2705 so guile.c can be very small (and eventuallly auto-generated. (I
2706 mean, generated mechanically, not self-generated. Hmm.))
2707 * guile.c, script.c, script.h: New source files.
2708 * init.c (scm_boot_guile_1): Call scm_init_script.
2709 * libguile.h: #include "script.h".
2710 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2711 targets, for new executable.
2712 (libguile_la_SOURCES): Mention script.c.
2713 (modinclude_HEADERS): Add script.h.
2714 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2715 not dynamic linking is enabled. This is because we're generating
2716 executables now. Move CY_AC_WITH_THREADS call after those, so the
2717 values of cy_cv_threads_libs captures the libs chosen above.
2718 * Makefile.in, configure, aclocal.m4: Regenerated.
2720 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2721 We don't maintain this interface any more, and it just confuses
2724 * alloca.c: #include <scmconfig.h>, not <config.h>.
2725 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2726 it'll get included in disties.
2728 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2730 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2731 be distributed, because they confuse people.
2732 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2734 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2736 * configure.in: check for presence of gethostent (not present on
2737 OpenBSD by default).
2738 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2739 * configure, scmconfig.h.in: Regenerated.
2741 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2743 * backtrace.c (scm_backtrace): Split message string across
2744 newlines properly. GCC is more tolerant of this than other
2747 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
2749 Merge threads directory into libguile.
2750 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
2751 threads.h: New source files.
2752 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
2753 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2755 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2756 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2757 coop-threads.c.cygnus, coop-threads.h.cygnus.
2758 * configure.in: If we're using threads, include threads.o in
2760 * _scm.h, libguile.h: threads.h lives in this directory now.
2761 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2762 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2763 currently used, but brought along for information's sake.
2764 * ChangeLog-threads: log from old 'threads' directory.
2765 * Makefile.in, configure: Rebuilt.
2767 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2769 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2772 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2774 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2776 Merge GH interface library into libguile.
2777 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
2778 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2779 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2780 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2782 (EXTRA_libguile_la_SOURCES): ... here.
2783 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2784 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2785 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2786 New variables, describing how to build the gh test programs.
2787 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2788 build the test programs, and we probably should have been linking
2789 libguile.la against them all along, to support AIX shared libs.
2790 Add cflags for threads to CFLAGS; add libs for threads to new
2791 variable THREAD_LIBS, used in Makefile.am.
2792 * ChangeLog-gh: log from old `gh' subdirectory.
2793 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2795 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2797 * acconfig.h: Undo change of Apr 9; including the definition of
2798 PACKAGE in the guile headers conflicts with applications' own
2800 * scmconfig.h.in: Regenerated.
2802 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

2806 * filesys.h: Added prototype.
2808 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
2809 when PROC is receiving no arguments.
2811 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2813 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2814 have S_IFSOCK. This is the case under Ultrix.
2816 * posix.c (scm_status_exit_val, scm_status_exit_val,
2817 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2818 Ultrix versions of WIFSTOPPED, etc., which assume that their
2819 arguments are lvalues (hmm).
2821 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2823 * eval.c: Doc fixes.
2825 * throw.c: Doc fixes; rearranged.
2827 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
2829 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
2831 * acconfig.h: Added entry for PACKAGE.
2832 * scmconfig.h.in: Regenerated.
2834 Changes to work with automake-1.1n, which has better libtool support.
2835 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2836 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
2838 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
2840 * Makefile.in: Rebuild.
2842 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2844 * stime.c (scm_mktime): take an optional zone argument.
2845 (scm_localtime): check putenv return value.
2846 (scm_strftime, scm_strptime): moved from posix.c. move #include
2848 stime.h, posix.h: update prototypes.
2849 (bdtime2c, setzone, restorezone): new static procedures.
2850 (scm_mktime, scm_strftime): use them.
2851 (scm_strftime): don't call mktime before strftime. Use
2852 filltime for return value.
2853 (filltime): convert NULL zname to #f.
2854 (scm_strptime): return a count of characters consumed, not
2855 the remaining string.
2857 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2859 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
2860 (scm_mktime): likewise.
2862 Uncomment localtime and mktime.
2864 * configure.in: add AC_STRUCT_TIMEZONE.
2866 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2868 * stime.c (scm_init_stime): don't define ticks/sec.
2869 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2870 return value problem and is still portable.)
2872 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2874 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2875 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2876 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2877 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2878 cpp_err_symbols.c): Corresponding changes.
2879 * Makefile.in: Regenerated.
2881 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2883 * posix.c (scm_putenv): don't check HAVE_PUTENV.
2884 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
2885 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
2886 * putenv.c: new file, from sh-utils 1.12.
2888 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2889 since allocation isn't for Scheme objects.
2890 (scm_putenv): copy strings before placing in the environment.
2892 * stime.c (scm_current_time): throw an error if time returns -1,
2893 instead of returning #f.
2894 (scm_get_internal_real_time, scm_get_internal_real_time): use
2895 scm_long2num for return value instead of SCM_MAKINUM.
2897 * stime.h: prototypes updated.
2899 * stime.c (scm_time_in_msec): apparently unused, deleted.
2901 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2903 * configure.in: check for gettimeofday.
2905 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2906 which may be more usefully portable than a gettimeofday interface.
2908 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2910 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
2912 * Makefile.in: Regenerated.
2914 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2916 * stime.c (filltime): recovered static procedure.
2917 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
2920 * posix.h: add prototype for scm_close_pipe, remove prototypes for
2921 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2923 * posix.c (scm_mknod): split the mode argument into type and perms
2924 arguments, like the extra fields returned by stat.
2926 * fports.c (scm_pipob): set the close, free and print procedures.
2927 (scm_close_pipe): new procedure.
2929 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2930 define them in boot-9.scm
2932 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2934 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
2935 wan't defined. Don't include fd.h.
2937 * Previously fd.h was regenerated whenever configure was run,
2938 forcing a couple of files to be recompiled.
2940 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
2941 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
2942 Check for _fileno as well as _file.
2944 * ioext.c: don't fd.h.
2945 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
2948 * Change the stratigy for getting information about errno
2949 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
2950 generating lists of symbols during the build process, which will
2951 not always work, include comprehensive lists in the distribution.
2952 To help keep the lists up to date, the "check_signals" and
2953 "check_errnos" make targets can be used.
2955 * configure.in: don't check for a command to extract errno codes.
2956 * Makefile.am: update file lists, remove errnos.list and errnos.c
2957 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
2958 check_errnos targets.
2959 (CLEANFILES): remove errnos.c and errnos.list, add
2960 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
2961 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
2962 * errnos.default: deleted.
2963 * cpp_signal.c: new file.
2964 * cpp_errno.c: renamed from errnos_get.c.
2965 * cpp_err_symbols, cpp_sig_symbols: new files.
2966 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
2967 * error.c (scm_init_error): #include cpp_err_symbols instead of
2969 * posix.c (scm_init_posix): don't intern signal symbols. #include
2972 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
2974 * strop.c (scm_i_index): allow the lower bound to be equal to the
2975 length of the string, so a null string doesn't always give an error.
2977 * posix.h: new prototypes.
2978 * posix.c (scm_status_exit_val, scm_status_term_sig,
2979 scm_status_stop_sig): new functions, as in scsh. They break down
2980 process status values as returned by waitpid.
2982 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
2984 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
2985 configure doesn't know about it.
2987 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2989 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
2991 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
2992 which defines C variables with global linkage.
2994 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2996 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
2999 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
3001 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
3002 has time to check why this doesn't work well with continuations.
3004 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
3006 * Fix shell syntax error; some shells won't tolerate
3007 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
3009 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3011 * posix.c (scm_uname): throw an error if uname fails instead
3014 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
3016 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
3019 * async.c (scm_ints_disabled): definition moved from error.c.
3021 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3023 * acconfig.h: Removed PACKAGE.
3025 * scmconfig.h.in: Regenerated.
3027 * snarf.h: g++ says it's non-portable not to specify the first
3028 argument in a varargs declaration. I introduced the first
3029 argument by using preprocessor conditionals.
3031 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
3033 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
3034 (scm_freopen): use RO string macros for filename and modes.
3035 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
3037 * posix.c (scm_getgrgid): simplify conversion of name to C string.
3038 (scm_mknod): use RO string macros for path.
3040 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
3041 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
3043 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
3044 use SCM_ROSTRINGP and SCM_ROCHARS.
3046 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3048 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
3051 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
3052 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
3053 support for byte vectors.
3055 * print.c (scm_iprin1): Limit number of vector elements printed
3056 according to pstate->length.
3058 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3060 * backtrace.c (scm_display_error_message): don't segv if message
3063 * error.h: prototype for scm_error_scm.
3065 * error.c (scm_error_scm): new procedure, reimplements scm-error
3066 in C and uses scm_error.
3068 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3070 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
3071 pointer to the Scheme variable read-hash-procedures and intern it
3072 in scm_init_read. Modify scm_read_hash_extend and
3073 scm_get_hash_procedure to use the pointer.
3075 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3077 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
3078 (SCM_KEYWORD_STYLE): defined.
3080 * read.c (scm_read_opts): add a keywords option. This isn't a
3081 boolean option, in case someone wants to add support for DSSSL
3083 Setup scm_keyword_prefix symbol.
3084 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
3086 I've left keyword support disabled by default, since it doesn't
3087 seem to break the module system and it gives R4RS standard behaviour.
3088 It can be reactivated with (read-set! keywords 'prefix).
3090 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3092 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
3093 before constructing arbiter.
3095 * eval.c (scm_m_define): Bugfix: Check that the object is a
3096 closure before setting the procedure property!
3098 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
3100 * ports.c: Removed `ungetc-char-ready?'.
3102 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
3104 * read.c (scm_init_read): intitialise scm_read_hash_procedures
3105 (idea from Mikael: make it a pair so scm_permanent object only
3107 (scm_read_hash_extend): don't call scm_permanent_object.
3108 (ideas from Mikael): if chr is already in the list, replace its
3109 procedure instead of appending it again. If proc is #f, remove
3111 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
3113 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
3115 * gdbint.c (gdb_read): update scm_lreadr usage.
3117 * load.h: update prototypes.
3119 * load.c (scm_primitive_load, scm_read_and_eval_x,
3120 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
3122 * read.h: add prototype for scm_read_hash_extend. Change args for
3125 * read.c (scm_read_hash_procedures): new variable.
3126 (scm_read_hash_extend): new procedure.
3127 (scm_get_hash_procedure): new procedure.
3128 (scm_lreadr): use scm_get_hash_procedure instead of an argument
3129 for extended # processing.
3130 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
3131 scm_read_token): remove case_i, sharp arguments. Change callers.
3133 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
3135 * read.h (SCM_N_READ_OPTIONS): increase to 3.
3136 (SCM_CASE_INSENSITIVE_P): define.
3138 * read.c: add case-insensitive option to scm_read_opts.
3139 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
3140 to determine whether to convert symbol case.
3141 (default_case_i): definition removed.
3142 * read.c (scm_read_token): if case_i, downcase ic before doing
3145 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3147 * configure.in: Added configuration option `guile-debug'.
3148 Configure with --enable-guile-debug if you want a bunch of extra
3149 functions used for debugging when developing Guile.
3151 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3153 * procs.c (make-cclo): New undocumented debugging procedure: Make
3154 compiled closure with internal procedure PROC and length LENGTH.
3155 Only compiled if GUILE_DEBUG is defined.
3157 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3159 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3161 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3163 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3164 with 3 or more args internally to the evaluator.
3166 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3168 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3169 with 3 or more args internally to the evaluator. This is mainly
3170 because we don't want to pass entry and exit points of the
3171 debug support twice, but it also seems to increase the speed of
3172 the evaluator for such calls (e. g. (+ 1 2 3)).
3174 * backtrace.c (scm_display_application): New procedure:
3175 display-application; Set fancy printing parameters individually
3176 for different types of display (backtrace, error, application).
3177 (These should of course be customizable!)
3179 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3180 clear the CHECK-flags.
3182 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3184 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3186 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3188 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3189 from pairs with a GLOC in the car.
3191 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3192 otherwise `symbol-hash' will behave badly.
3193 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3194 we get segmentation fault!
3196 * symbols.c: Added #include "weaks.h". New functions:
3197 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3198 moved to an extraneous library when we split libguile.)
3200 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3202 * filesys.c (scm_stat): stat now takes fport arguments too as
3203 documented in the manual.
3205 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3207 * debug.c (scm_single_step): Bugfix: Call continuation with
3208 scm_call_continuation instead of throwing to it.
3210 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3212 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3213 argument wasn't declared to be optional.
3215 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3217 * stime.c (scm_init_stime): Add feature "current-time".
3219 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3221 * throw.h: prototype for scm_exit_status.
3222 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3223 args to derive an exit status. Allows (quit) to work from a
3225 (scm_exit_status): new function.
3228 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3230 * eval.c (scm_deval): Removed some old code.
3231 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3233 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3236 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3239 * procs.c: Introduce the existent C function scm_thunk_p at the
3240 Scheme level as well.
3242 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3244 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3245 used from C to easily lookup the value of a symbol in the current
3248 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3250 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3251 scm_init_unif in this file. This will also fix a previous problem
3254 * configure.in: Added AM_MAINTAINER_MODE
3256 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3258 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3261 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3263 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3264 source files that are not always included in libguile but should
3265 have their dependencies calculated by automake. This variable is
3266 recognized by automake, no further magic is needed.
3267 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3268 to deal exclusively with *.lo files, as it seems. The *.o files
3269 are built automatically when the corresponding *.lo file gets
3272 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3274 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3277 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3279 * unif.c (scm_array_set_x): minor change to argument error checking.
3281 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3283 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3284 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3285 They should only be included in the library at configure.in's
3287 (libguile_la_LDADD): Include the appropriate .lo files here.
3288 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3289 so we know when to build them (and their .lo bretheren).
3290 * configure.in (LIBLOBJS): New substituted variable. We let
3291 configure decide which .o files to include in LIBOBJS, and then
3292 put the corresponding list of .lo files in LIBLOBJS. The latter
3293 is what we pass to libtool.
3294 * Makefile.in, configure: regenerated.
3296 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3298 * symbols.c (scm_sysintern0): New function. Contains the core of
3299 old scm_sysintern but doesn't take a second value argument.
3300 (scm_sysintern): Now uses scm_sysintern0.
3301 (scm_sysintern_no_module_lookup): Renamed to
3302 scm_sysintern0_no_module_lookup and doesn't take a second value
3303 argument any longer.
3305 * symbols.h (scm_sysintern0: Added declaration.
3307 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3308 scm_sysintern when interning option keys. Otherwise we risk
3309 destroying the values of already interned variables.
3311 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3312 scheme-level boolean (use SCM_NFALSEP).
3314 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3316 (scm_backtrace): New function. (C version of old function from
3317 boot-9.scm) Motivation: Make it possible to display backtraces
3318 without depending on boot-9.scm. (I'm uncertain if this
3319 motivation is good enough...)
3321 * root.h (scm_root_state): Add member the_last_stack_var.
3322 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3324 * root.c (mark_root): Mark scm_the_last_stack_var.
3326 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3329 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3331 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3332 1. mark_lazy_catch didn't mark the smob.
3333 2. Both functions above have standard variants:
3334 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3335 free_lazy_catch --> scm_free0.
3337 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3339 * throw.c (scm_internal_lazy_catch): New function.
3340 (scm_lazy_catch): Rewritten to use it.
3341 (scm_ithrow): Handle the new lazy catch representation.
3342 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3343 that doesn't have a jmpbuf is a lazy catch clause.
3344 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3345 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3346 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3348 (scm_init_throw): Register the new lazy-catch smob type.
3349 * throw.h (scm_internal_lazy_catch): decl for new function.
3351 * throw.c (scm_internal_catch): Doc fixes.
3353 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3354 configure.in. Including this might cause problems if applications
3355 that link against libguile include their own copies of alloca, but
3356 if they're using autoconf, they should be adding libguile to LIBS
3357 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3358 the copy in libguile, and things will be okay. (I think.)
3360 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3362 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3364 strop.h: move prototypes too.
3366 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3368 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3371 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3372 etc. I deleted them from filesys.c long ago, but didn't
3373 notice they were here too (although ineffective since
3374 sys/stat.h wasn't included).
3376 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3378 * eval.c: Don't define alloca in GCC case. gcc will automatically
3379 use __builtin_alloca if appropriate.
3381 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3383 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3384 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3385 that values of automatic variables are preserved. See comments
3386 for safe_setjmp for details.
3388 Change from Thomas Morgan:
3389 * variable.c: Include eq.h.
3390 (var_equal): New function.
3391 (variable_smob): Use var_equal as the discriminator for variables.
3393 * throw.c (s_throw): Remove extraneous declaration.
3395 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3396 * eval.c: Add necessary CPP cruft to support that.
3397 * configure, Makefile.in, scmconfig.h.in: regenerated.
3399 Change from Thomas Morgan:
3400 * procprop.c (scm_procedure_properties): Convert the Scheme
3401 boolean returned by scm_procedure_p into a C boolean before using
3402 it as a condition for SCM_ASSERT.
3403 (scm_procedure_property): Likewise.
3405 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3406 indications of Unixness.
3409 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3411 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3413 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3415 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3416 "unknown # object" error messages.
3418 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3419 (scm_i_index) and declare it static. Add a 'direction' argument
3420 to indicate what way the search should go.
3421 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3423 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3424 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3426 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3428 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3430 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3431 to avoid clash with various scsh forks.
3433 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3435 The following two changes (ramap.c, throw.c) are motivated by the
3436 apparent unportability of forward declarations of static arrays of
3437 the form `static foo bar[];'.
3439 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3440 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3442 * throw.c (scm_throw): Moved above scm_ithrow.
3444 * options.h: Removed the extern declarations of scm_yes_sym and
3445 scm_no_sym since these are static.
3447 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3449 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3451 * Makefile.am: remove AWK=@AWK@.
3452 Add a rule for generating errnos.list.
3453 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3455 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3456 don't extract errnos, just set a variable (avoids the
3457 need to recompile error.c just because configure is run.)
3459 * unif.h: update prototypes.
3460 * unif.c (scm_uniform_array_read,write): change the offset and
3461 length arguments to start and end, for consistency.
3463 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3465 * ioext.h: update prototypes.
3466 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3467 scm_read_line_x, it's a more general procedure using an
3468 interface from scsh. read-line and read-line! are now defined
3470 Note that the new read-line trims the terminator
3471 by default, previously it was appended to the returned string. An
3472 optional argument specifies how to process the terminator (scsh
3473 compatible). For the old behaviour: (read-line port 'concat).
3474 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3475 returns a pair, but is converted to multiple values if the scsh
3478 socket.h: update prototypes.
3479 * socket.c (scm_recvfrom): for consistency with other procedures,
3480 take start and end as separate optional arguments.
3481 (scm_recv, scm_recvfrom): don't allow the second argument
3482 to be a size, only a buffer. Change the scheme names to
3483 recv! and recvfrom!. Don't return the buffer.
3485 * ioext.h, posix.h: move prototypes too.
3486 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3487 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3488 "read.h" and "unif.h".
3489 * ioext.c: include "chars.h"
3491 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3493 * dynl.c: The dynamic linking and module registration functions
3494 are now defined even when dynamic linking is not available for the
3495 host system. Some of their functionality can be done without
3496 dynamic linking; when it's really needed, they throw errors.
3498 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3500 * configure.in: Only define DYNAMIC_LINKING when one of the system
3501 dependent functions is detected.
3502 * dynl.c (scm_dynamic_func): New function to get the address of a
3503 function in a dynamic object.
3504 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3505 produced by scm_dynamic_func as the thing to call.
3507 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3509 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3510 (scm_register_module_xxx, scm_registered_modules,
3511 scm_clear_registered_modules): New functions.
3513 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3515 * symbols.c (scm_sysintern): Renamed to
3516 scm_sysintern_no_module_lookup.
3517 (scm_sysintern): New function to take the place of the old
3518 scm_sysintern. It uses the current toplevel lookup closure to give
3519 the symbol its value. This is a temporary hack to put packages
3520 like gtcltk into their own module.
3521 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3522 us whether `scm_top_level_lookup_closure_var' has been initialized
3524 * eval.c (scm_init_eval): Set it.
3526 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3528 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3529 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3531 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3533 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3534 scm_sys_dup): deleted: FD capability will be added to other
3536 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3537 scm_fd_free, fd_smob, scm_intern_fd.
3538 (scm_open): renamed from scm_sys_open. Return a port instead of
3539 an FD object. Make the mode argument optional.
3540 (scm_sys_create): deleted, it's just a special case of open.
3541 (scm_init_filesys): move interning of constants O_CREAT etc.,
3542 here (were previously using SCM_CONST_LONG macro).
3543 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3545 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3546 include "fports.h" and <stdio.h>
3547 (scm_stat, scm_select): don't support FD objects.
3549 * error.h: adjust scm_syserror_msg prototype.
3550 * error.c (scm_syserror_msg): take an extra argument for errno.
3551 Using the global value didn't always work, since it could be
3552 reset by procedure calls in the message or args arguments.
3554 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3555 I don't understand why the check was there (and what about the
3558 * strop.c (scm_string_copy): allow shared substrings to be copied.
3560 * unif.h: corresponding change to prototypes.
3561 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3562 recognize two new optional arguments: offset and length. Allow
3563 the port argument to be an integer (file descriptor, for scsh).
3564 Include <unistd.h> for "read" prototype.
3566 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3568 * socket.c: don't include filesys.h.
3570 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3572 * Makefile.am: add AWK=@AWK@ (?)
3574 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3576 Add a rule to generate errnos.c from errnos.
3577 * error.c (scm_init_error): include errnos.c.
3578 * errnos_cnvt.awk: new file, converts the list of errno codes to
3580 * errnos_get.c: new file.
3581 * errnos.default: new file, contains errnos to try if they can't
3582 be extracted from errno.h.
3583 * configure.in: if using GCC, try and extract errno codes from
3587 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3589 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3590 * Makefile.am: Made libguile into a libtool library.
3591 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3592 Set libtool_libs to indicate that libguile is a libtool library.
3593 See guile/ChangeLog for details.
3594 * .cvsignore: ignore "*.lo", the libtool library objects.
3596 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3598 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3599 use htons in getservbyport argument.
3601 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3603 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3604 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3607 * objprop.c (scm_object_property): No need to take the CDR of the
3608 value returned by scm_object_properties, since Aug 20 change.
3610 * configure.in: When checking for struct linger, #include
3611 <sys/types.h> as well as <sys/socket.h>. I've never known
3612 <sys/types.h> to cause any portability problems, and Solaris's
3613 <sys/socket.h> needs it.
3614 * configure: Rebuilt.
3616 I think the Sun compiler has chosen a perverse way to interpret
3617 ANSI declarations combined with K&R definitions. We'll
3618 appease it a little bit. But when it invades France, we fight.
3619 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3620 * print.h (scm_iprlist): Here too.
3621 * numbers.c (scm_divbigdig): Change definition to match
3622 declaration in numbers.h.
3623 * unif.c (scm_makflo): Change definition to match declaration in
3626 * init.c (scm_boot_guile): Don't return the value of
3627 scm_boot_guile_1. This function doesn't return a value;
3628 scm_boot_guile_1 doesn't return a value (or return at all).
3630 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3633 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3634 compile. I have a feeling this function is a bad idea anyway ---
3635 one should always test for features, not systems.
3637 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3638 semicolons. Only pure luck kept this from being noticed earlier.
3640 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3642 * socket.c (scm_recvfrom): Added missing semicolon.
3644 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3646 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3647 the buffer and start and end positions for scsh networking
3650 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3652 * configure.in: Revert previous change to this file; the problem
3653 is due to transient automake weirdness.
3654 * configure: Rebuilt.
3656 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3657 PLUGIN/guile.libs. configure generates the latter from the former.
3658 * Makefile.in: Rebuilt.
3660 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3661 need this if we install scripts, like guile-snarf.
3662 * configure: Rebuilt.
3664 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3666 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3668 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3670 * socket.c (scm_addr_vector): fix faulty scm_listify.
3672 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3674 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3675 style block comment is no longer considered an error.
3677 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3679 * PLUGIN/guile.libs.in: New file.
3680 * PLUGIN/guile.libs: Removed from repository.
3681 * configure.in: Create PLUGIN/guile.libs from
3682 PLUGIN/guile.libs.in. This is for including additonal libraries
3683 needed for dynamic linking.
3684 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3685 instead of PLUGIN/guile.libs.
3687 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3689 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3691 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3692 occurrences of the given element from the list, not just the
3693 first. This is how the Emacs Lisp functions behave, how the
3694 analogous Common Lisp functions behave, and (I believe) how the
3695 older Maclisp functions worked. I realize that this change may
3696 break code, but it seemed better to break it before the Guile
3699 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3700 Their prototypes were already present in gc.h, but they weren't
3702 (scm_init_storage): Initialize scm_protects.
3703 * root.c (scm_protects): New element of scm_sys_protects.
3705 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3707 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3709 * libguile.h: Added #include "libguile/net_db.h".
3711 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3712 30 change. That file is only meant for communication between the
3713 configuration process and load.c. If code linked against libguile
3714 wants to get at the paths mentioned in libpath.h, it can call
3715 functions declared in load.h.
3717 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3719 * libguile.h: Removed #include "libguile/fdsocket.h"
3721 * net_db.c: Added #include <sys/socket.h>.
3723 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3725 * filesys.c (scm_input_waiting_p): use select in preference to
3726 FIONREAD, since the latter doesn't detect EOF.
3727 Throw error if neither select nor FIONREAD available.
3729 * socket.c (scm_connect): take a port, not a fd object.
3730 (scm_fill_sockaddr): throw an error if fam is not recognised.
3731 (scm_bind): use scm_fill_sockaddr.
3732 (scm_listen): take a port, not a fd object.
3733 (scm_accept): take and return a port. return #f in the car if
3734 address can't be got
3735 (scm_sock_fd_to_port): new procedure.
3736 (scm_socket): use scm_sock_fd_to_port.
3737 (scm_addr_vector): throw error if unrecognised address type.
3738 take an extra argument with the calling procedure name.
3739 (scm_getsockname): take a port. return #f if address can't be got.
3740 (scm_getpeername): take a port. return #f if address can't be got.
3741 (scm_recvfrom): take a port. return #f for address component if can't
3743 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3744 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3746 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3748 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3749 use separate data pointers, to allow them to be designed
3750 independently and reused.
3751 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3752 Renamed from catch_body, catch_handler, and uncaught_throw; made
3754 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3756 (scm_catch): Use the above.
3757 (scm_throw): Don't bother printing a message for an uncaught
3758 throw; we establish a default handler in init.
3759 * throw.h (scm_internal_catch): Prototype updated.
3760 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3762 (struct scm_body_thunk_data): New structure, used as data
3763 argument to scm_body_thunk.
3764 * init.c (struct main_func_closure): New structure, packaging up
3765 the data to pass to the user's main function.
3766 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3767 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3768 scm_internal_catch to establish a catch-all handler, using
3769 scm_handle_by_message. This replaces the special-case code in
3771 (invoke_main_func): Body function for scm_internal_catch; invoke
3772 the user's main function, using the main_func_closure pointer to
3773 decide what to pass it.
3774 * root.c (struct cwdr_body_data): Remove handler_proc member.
3775 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3776 (cwdr_handler): Removed.
3778 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3780 * socket.h (SCM_P): update bind prototype.
3781 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3782 include "feature.h".
3783 (scm_socket): return a port, not a file descriptor object.
3784 include "fports.h" and <unistd.h>
3785 (scm_bind): take a port, not a file descriptor object.
3786 take an extra argument for address args.
3788 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3789 INADDR_NONE, INADDR_LOOPBACK.
3791 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3793 * init.c: include net_db.h and not fdsocket.h.
3794 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3796 * Makefile.am: corresponding changes.
3797 * socket.h: renamed from fdsocket.h, fix names.
3798 * net_db.h: renamed from socket.h, fix names.
3799 * socket.c: renamed from fdsocket.c.
3800 remove _sys from procedure names.
3801 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3802 add "socket" to features list.
3803 * net_db.c: renamed from socket.c.
3804 remove _sys from procedure names.
3805 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3806 add "net-db" to features list.
3807 include "net_db.h". don't include <sys/socket.h> or
3810 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3812 * tags.h (scm_tags): Removed comma at end of last enumerator.
3814 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3816 Don't use GCC extensions to allocate space for debugging frames.
3817 (Here he goes again! Why do we put up with this?!)
3818 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3819 an scm_debug_info structure, not an in-line array of them. Add
3820 'info' member, to say how many vect elements we've used, for eval
3822 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3823 a new variable debug_info_end to mark the end of vect, instead of
3824 the address of the 'info' pointer itself.
3825 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3826 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3827 (SCM_APPLY): Explicitly allocate space for debug.vect.
3828 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3829 * stacks.c: Adjusted for new debug frame structure.
3830 (RELOC_INFO, RELOC_FRAME): New macros.
3831 (stack_depth, read_frames): Use them, and new scm_debug_frame
3832 element 'info', instead of magically knowing that eval frames have
3833 an info pointer sitting after vect.
3834 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3836 (scm_init_stacks): Formatting tweaks.
3838 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3840 Give GCC more control flow information, so it can be sure that
3841 variables aren't used uninitialized.
3842 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3843 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3844 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3845 scm_misc_error): Tell GCC that these functions never return.
3846 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3847 out the field type, call abort if SCM_ASSERT returns, to placate
3849 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3850 scm_wta ever returns. We can't handle this case anyway, and this
3851 gives the optimizer more information.
3852 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3853 scm_wta ever returns.
3855 In some cases, the code is fine, but GCC isn't smart enough to
3856 figure that out; this usually happens when one variable is only
3857 initialized and used when a particular condition holds true, and
3858 we know that condition will never change within a given invocation
3859 of the function. In this case, we simply initialize the variables
3860 to placate the compiler, hopefully to a value which will cause a
3861 crash if it is ever actually used.
3862 * print.c (scm_iprin1): Initialize mw_pos.
3863 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3864 * throw.c (scm_ithrow): Initialize dynpair.
3865 * unif.c (scm_uniform_vector_ref): Initialize cra.
3866 * struct.c (init_struct): Initialize prot.
3867 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3869 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3870 if EXPR contains no expressions.
3872 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3874 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3875 cause an infinite loop (???). So much for the algebraic
3876 equivalency of variable-sized arrays and alloca...
3878 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3880 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3881 a SCM boolean, not a C boolean.
3883 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3885 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3886 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3887 rules for raising scm_mtrigger. Previously, unfortunate but not
3888 unlikely circumstances could result in almost constant invokation
3889 of the gc. Now, this situations should be less likely, but they
3890 are not prevented completely.
3892 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3894 * numbers.c (scm_fuck): Procedure removed; looks like old test
3896 * numbers.h: Prototype removed.
3898 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3900 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3901 array to a pointer, to match my Nov 21 change in eval.c.
3903 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3905 * libguile.h: Added #include "libguile/backtrace.h", #include
3906 "libguile/stacks.h".
3908 * strings.c (scm_string scm_make_string scm_string_ref
3909 scm_string_set_x scm_string_equal_p scm_string_append):
3910 Bugfix according to scm patch from Aubrey Jaffer:
3911 Corrected long-standing
3912 (not (eqv? (integer->char 128)
3913 (string-ref (make-string 1 (integer->char 128)) 0)))
3914 bug found by John Kozak <jk@noontide.demon.co.uk>.
3916 * strports.c, strports.h: Make scm_eval_0str return the value of
3917 the last expression evaluated (previously, it returned void).
3919 * strports.c, strports.h: New function: scm_read_0str. Does what
3922 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3924 * simpos.c (scm_getenv): return #f if string can't be found in the
3925 environment instead of throwing an exception, for compatibility
3926 with numerous other systems.
3928 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3930 * Makefile.am (.c.x): Use guile-snarf.
3931 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
3933 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
3935 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3937 * backtrace.c (scm_display_error_message): Made non-static, and
3938 renamed from display_error_message.
3939 * backtrace.h (scm_display_error_message): Added extern decl.
3940 * throw.c (uncaught_throw): Use it to display the error message.
3942 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
3944 * inet_aton.c: Use #if 0, not #ifdef 0.
3946 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
3948 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
3949 to convert the returned value.
3950 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
3951 the offset argument.
3953 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3955 Add new interface to catch/throw, usable from C as well as
3957 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
3958 (scm_internal_catch): New function, replaces...
3959 (scm_catch_apply): Deleted.
3960 * throw.c (scm_catch_apply): Deleted; replaced with a more general
3961 mechanism which is a bit more code, but can be used nicely from C
3962 and implement the Scheme semantics as well.
3963 (scm_internal_catch): This is the replacement; it's named after
3964 the analogous function in Emacs.
3965 (scm_catch): Reimplemented in terms of the above.
3966 (struct catch_body_data, catch_body, catch_handler): New
3967 functions, used by scm_catch.
3968 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
3969 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
3970 support for new cwdr.
3972 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
3975 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
3977 * acconfig.h: Added DYNAMIC_LINKING symbol.
3978 * configure.in: Add option and checks for dynamic linking.
3979 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
3980 dynl.h: New files for dynamic linking support.
3981 * Makefile.am (libguile_a_SOURCES):
3983 (modinclude_HEADERS): Added "dynl.h".
3984 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
3986 * init.c (scm_boot_guile_1): Call
3987 scm_init_dynamic_linking to initialize dynamic linking support.
3989 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
3991 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
3992 (as we Schemers say). It needs to be global, so that I can tweak
3993 it for the proper operation of unexec.
3994 (scm_boot_guile_1_live): New variable, see above.
3996 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
3998 * guile-snarf.sh: Removed.
3999 * PLUGIN/guile.libs: Added dependency for -lm.
4000 * acinclude.m4: Renamed from aclocal.m4.
4001 * PLUGIN/greet: Removed.
4002 * Makefile.am, aclocal.m4: New files.
4003 * configure.in: Updated for Automake.
4005 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
4007 * eval.c (scm_definedp): Use top_level_lookup_closure_var
4008 and not top_level_lookup_thunk_var.
4010 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
4012 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
4014 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
4016 * eval.c (scm_definedp): Incompatibly changed to be a builtin
4017 Scheme function, instead of syntax. Single argument is now a
4020 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4022 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
4023 scm_ra_divide): Properly terminate statements passed as arguments
4024 to IVDEP macros. (Thanks to Bernard Urban.)
4026 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
4027 with non-constant sizes. (Thanks to Bernard Urban.)
4029 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4031 It's an "eval closure", not an "eval thunk." A thunk is a
4032 function of no arguments.
4033 * root.h (struct scm_root_state): Renamed
4034 top_level_lookup_closure_var from top_level_lookup_thunk_var.
4035 (scm_top_level_lookup_closure_var): Renamed from
4036 scm_top_level_lookup_thunk_var.
4037 * root.c (mark_root): Uses changed.
4038 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
4039 * init.c (scm_start_stack): Uses changed.
4040 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
4041 Change scheme-visible name to *top-level-lookup-closure* from
4042 *top-level-lookup-thunk*.
4044 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
4046 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
4047 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
4049 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
4051 * gc.c (struct scm_heap_seg_data): Doc fixes.
4053 * gc.c (scm_gc_sweep): Empty all segments' freelists before
4054 sweeping. Then, prepend each segment's free cells to its
4055 freelist, rather than wiping out the old value. (Thanks to Marius
4058 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
4059 scm_check_freelist, scm_debug_newcell): New functions and
4060 variables, for debugging freelist problems.
4061 * pairs.h (SCM_NEWCELL): New debugging version added.
4062 * gc.h (scm_debug_newcell): Added extern declaration, used by
4063 debugging version of SCM_NEWCELL.
4065 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4067 On some systems <libc.h> conflicts with <unistd.h>, and should not
4068 be #included at all.
4069 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
4070 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
4071 * configure.in: Call it.
4072 * posix.c, filesys.c: Use its results to decide whether or not to
4074 * configure, scmconfig.h.in: Rebuilt with autoconf and
4077 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4079 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
4080 pointer to the stdio stream before calling scm_setbuf0, so the
4081 latter will be able to retrieve it. I'm surprised this didn't
4082 segfault earlier. (Thanks to Christopher Lee.)
4084 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4086 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
4089 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4091 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
4092 number of stack narrowing specifier pairs. The first specifier in
4093 a pair controls inner border, the second the outer border. A
4094 number means cut that number of frames, a procedure object means
4095 cut until that object is found in operator position in a frame.
4097 * root.c (cwdr): Bugfix.
4099 * read.c: Recording of positions disabled by default.
4101 * procs.c (scm_closure_p): New function.
4103 * posix.c (scm_tmpnam): New function.
4105 * load.c: Added #include "throw.h".
4106 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
4109 * load.c, load.h (scm_read_and_eval_x): New function.
4111 * eval.c: Renamed debug option "deval" to "debug".
4113 (scm_eval_x): `eval!' is no longer accessible from the scheme
4114 level. Motivation: We can't allow operations which introduce
4115 glocs into the scheme level. Guile's type system can't handle
4116 these as data. Use `eval' or `read-and-eval!' as replacement.
4118 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
4119 SCM_CONSP since this is a macro!; Set vframe.prev to
4120 scm_last_debug_frame instead of 0. In this way we can look
4121 "above" the virtual start stack frame if we wish.
4122 (scm_debug_hang): New function: Useful for debugging Guile in
4123 certain tricky situations. Will probably be removed later...
4125 * debug.h: Changed semantics of debug option "backtrace". This
4126 option now only indicates whether we want automatic backtrace at
4129 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4131 * ports.c: #include "filesys.h"
4132 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
4134 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
4135 Motivation: This is system specific code which is related to file
4136 I/O. It also may use select. Added code by Gary Houston to
4137 detect presence of character in stdio buffers.
4139 * libguile.h: #include "libguile/libpath.h"
4141 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4142 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4143 SCM_SITE_DIR; Install libpath.h among the other include files.
4145 * load.c, load.h (scm_sys_package_data_dir): New function.
4147 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4149 * stacks.h: Bugfix: Don't use tail-array length field as stack
4150 length field! This screwed GC.
4152 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4154 * _scm.h: Added #ifndef around definition of macros min and max.
4156 * __scm.h: Added hooks for threads to plugin to in ints protection
4157 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4158 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4159 the main code in these macros duplicated and spread over multiple
4160 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4161 SCM_THREAD_SWITCHING_CODE.
4163 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4165 * snarf.h: New file.
4166 * guile-snarf.sh: New file.
4167 * Makefile.in (inner_h_files): Added snarf.h
4168 (ancillary, install, uninstall, distclean): Added actions for
4170 (.c.x): Use guile-snarf.
4171 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4172 (gen_c_files): Note that these depend on guile-snarf.
4173 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4174 now in "snarf.h". Added #include "snarf.h" to get them.
4175 * libguile.h: Added #include "snarf.h".
4176 (Patches applied and tweaked by Jim Blandy.)
4178 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4180 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4181 standards suggest against providing prototypes for system
4182 functions. Thanks to Greg Troxel.
4184 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4186 * strports.c (scm_eval_0str): New function.
4187 #include "read.h", to get prototype for scm_read.
4188 * Makefile.in (strports.o): Update dependencies.
4189 * strports.h: New prototype.
4191 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4192 scheme name from "int?" to "integer?". It seems to do the job.
4193 * numbers.h: Rename prototype too.
4194 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4197 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4198 scm_num_eq_p): Rename these according to R4RS conventions: call
4199 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4200 to making libguile R4RS compliant without ice-9...
4202 * load.c (scm_sys_search_load_path): Search for files under all
4203 extensions listed in the %load-extensions variable. If FILENAME
4204 is absolute, return it unchanged, without searching the load path.
4205 (scm_loc_load_extensions): New variable, pointing to
4206 %load-extensions' value cell.
4207 (scm_init_load): Initialize it, and the value it points to.
4208 (scm_primitive_load_path): Improve error reporting.
4210 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4211 of new Scheme variable %load-hook.
4212 (scm_primitive_load): Apply %load-hook to filename.
4214 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4216 * configure.in: add tests for figuring out whether buffered data
4217 is available in a FILE structure, which is needed by char-ready.
4219 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4222 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4223 exceptions using misc_error instead of syserror. It seems a bit
4224 odd to throw an exception if a string can't be found in the
4225 environment, but it's consistent with open-file, stat etc.
4226 (simpos.h): remove sys_ from getenv.
4228 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4229 occurs, throw an error instead of returning errno. Return value
4231 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4233 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4235 * filesys.c (scm_stat2scm): derive file type and permissions from
4236 the stat mode and append them to the returned vector.
4237 There isn't much overhead in doing this and it avoids the need to
4238 work with S_IRUSR et al. in Scheme.
4239 Define symbols scm_sym_regular etc.
4240 (scm_init_filesys): don't intern S_IRUSR etc.
4242 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4243 and s_primitive_load_path.
4245 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4247 * error.h: don't declare error symbols. prototype for scm_misc_error.
4249 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4252 * error.c: use SCM_SYMBOL to set up error keys.
4253 scm_misc_error: new procedure.
4255 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4257 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4258 between `#!' and `!#' is ignored.
4259 (skip_scsh_block_comment): New function.
4261 * feature.c (scm_set_program_arguments): New argument, FIRST.
4262 * feature.h: Update prototype.
4263 * init.c (scm_boot_guile_1): Pass new argument to
4264 scm_set_program_arguments.
4266 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4268 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4269 (scm_boot_guile): Call scm_set_program_arguments here, later than
4270 the old initialization.
4272 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4273 initialization procedure.
4274 - Delete in, out, err arguments; there are other perfectly good
4275 ways to override these when desired.
4276 - Delete result argument; this function shouldn't ever return.
4277 - Rename init_func argument to main_func, for less confusion.
4278 - Delete boot_cmd argument; main_func is more general.
4279 -Add 'closure' argument, to help people pass data to main_func
4280 without resorting to global variables.
4281 - Abort if reentered; don't bother returning an error code.
4282 - Call scm_init_standard_ports to set up the default/current
4283 standard ports; no need to pass them to scm_start_stack.
4284 - Remove code to evaluate the boot_cmd, and start the repl; let
4285 the user do something like that in main_func if they want.
4286 - Remove code to package up a return value; main_func can do any
4288 - Call exit (0), instead of returning.
4289 (scm_start_stack): Don't initialize the I/O ports here; that's
4290 weird. Delete in, out, err arguments. Move guts to
4291 scm_init_standard_ports, scm_stdio_to_port.
4292 (scm_init_standard_ports): New function, to set up current and
4293 default standard ports.
4294 (scm_start_stack, scm_restart_stack): Make these static.
4295 * init.h (scm_boot_guile): Adjust declaration.
4296 (scm_start_stack, scm_restart_stack): Remove externally
4297 visible declarations for these.
4298 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4300 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4301 written out several times in scm_start_stack.
4302 * fports.h: New declaration for the above.
4304 * feature.c (scm_set_program_arguments): New function.
4305 * feature.h: New declaration for the above.
4307 * ports.c: Formatting tweak.
4309 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4311 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4312 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4313 for obtaining the address of a car or cdr field. Motivation:
4314 &SCM_CXR make assumptions about the internal structure of the
4317 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4318 Motivation: see SCM_CXRLOC.
4320 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4321 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4322 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4323 Motivation: Safer use. Some other macros are defined in terms of
4324 these operations. If these are defined using the SCM_SETCXR
4325 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4326 to inefficiency and an <e1> with side-effects could potentially
4327 break. Also, these particular operations are heavily utilized in
4328 the garbage collector. In unoptimized code there will be a
4331 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4332 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4333 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4334 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4335 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4336 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4337 vports.c: Cleaned up use of pairs: Don't make any special
4338 assumptions about the internal structure of selectors and
4339 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4340 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4341 (Among other things, this change makes it easier to build Guile
4342 with certain compilers which have problems with casted lvalues.)
4344 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4346 * stacks.c: Improve selection of relevant stack frames when making
4347 a stack object. Introduce one level of indirection in the stack
4348 object to make it possible to "narrow" to a certain region of the
4349 stack. This facilitates making use of more clever algorithms (not
4350 implemented) for selecting relevant frames and gives a cleaner
4351 design since selection of frames can be done independently of
4352 extraction of frames from the real stack.
4353 (scm_stack_id): Also take #t as argument which means look at
4356 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4357 Turn n_tail into an integer directly representing current number
4358 of frames in stack. Add field tail.
4360 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4362 * debug.c (scm_make_memoized): Made it available at scheme level.
4363 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4364 SCM_NIMP before applying heavier predicates in argument checking.
4365 (scm_local_eval): Also take memoized object as argument.
4367 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4368 aren't created with zero length, but should such a strange
4369 creature suddenly turn up...
4371 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4373 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4374 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4376 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4378 * variable.c (scm_make_variable): Make the name hint optional, as
4380 (anonymous_variable_sym): Renamed from variable_sym. All uses
4383 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4384 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4385 of scm_primitive_load_path was also changed to
4386 "primitive-load-path", from "%try-load-path". Callers changed.
4387 We'd like to respect the convention that a function named
4388 "try-mumble" should behave just like the function called "mumble",
4389 but return #f instead of signalling some error.
4390 * load.h: Rename prototypes.
4392 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4394 * print.c (make_print_state, grow_print_state), print.h: Modified
4395 the print state representation: Don't use a tail array for
4396 recording of circular references. Resizing of the print state
4397 structure invalidates the print state pointer. To avoid passing
4398 around an indirect print state reference to all printing
4399 functions, we instead let the print state reference a resizable
4402 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4404 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4405 Don't crash when passed an improper list terminated by a
4406 non-immediate value.
4408 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4410 Allocate data for structures on an eight-byte boundary, as
4411 required by the tagging system.
4412 * struct.c (alloc_struct): New function.
4413 (scm_make_struct, scm_make_vtable_vtable): Call it.
4414 * struct.h (scm_struct_n_extra_words): Bump to 3.
4415 (scm_struct_i_ptr): New "field".
4416 * gc.c (scm_gc_sweep): When we need to free the data, use the
4417 information stored by alloc_struct to find the beginning of the
4418 block allocated to the structure, so we can free it.
4420 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4422 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4425 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4426 (scm_debug_info): New member: id.
4428 * stacks.c: Stacks are now represented as structs; Stacks have an
4429 id given to them by `start-stack'.
4430 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4432 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4433 Changed stack representation.
4435 * debug.c (scm_procedure_name): Try procedure property `name' for
4436 compiled closures aswell.
4438 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4440 * eval.c: scm_i_name moved to gsubr.c
4441 (scm_m_define): Record names of all kinds of procedure
4442 objects. (Earlier, only closures were recorded.)
4444 * procprop.h: Added declaration of scm_i_name.
4446 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4447 (scm_make_gsubr): Record names of compiled closures.
4449 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4451 * debug.c, debug.h: Removed obsolete code.
4453 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4454 stacks.c: Renamed regs --> scm_contregs.
4456 * print.c (scm_free_print_state): Cleanup print state before
4457 returning it to pool. It is better to do it here than in
4458 scm_prin1 since scm_prin1 is called often.
4460 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4461 s_set_source_property_x): Check that first argument is a pair or a
4464 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4465 scm_i_line, scm_i_column and scm_i_breakpoint global.
4467 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4468 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4471 * debug.h: Added debug object smob declaration and macro
4474 * configure.in: Build with backtrace.o and stacks.o if debug
4477 * Makefile.in: Added entries for new files: backtrace.c,
4478 backtrace.h, stacks.c and stacks.h.
4480 * symbols.c (scm_sym2ovcell): Fixed documentation.
4482 * _scm.h (min, max): Added.
4484 * async.c: Moved `min' macro to _scm.h.
4486 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4487 SCM_BACKTRACE_INDENT.
4489 * eval.c: Added new debug options `maxdepth' and `indent'.
4491 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4493 * print.h: Added selector SCM_PRINT_STATE.
4495 * print.c: New functions: scm_make_print_state,
4496 scm_free_print_state.
4498 * print.h: Added declarations for scm_make_print_state,
4499 scm_free_print_state.
4501 * debug.c (scm_m_start_stack): New acro.
4503 * debug.h: Small cleanup.
4505 * init.c (scm_boot_guile_1): Moved scm_init_debug below
4508 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

4528 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
4529 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
4530 declare functions with prototypes. (Patch thanks to Marius
4533 More prototype-related changes from Marius Vollmer:
4534 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4535 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4536 * ports.h (ptobfuns): Added prototypes. This means some casting in
4538 * fports.c: Added casts for initializations, since the functions
4539 are defined to take FILE * as their stream argument, not SCM.
4540 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4541 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4542 to `char *str_data' to conform to prototype.
4544 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4546 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4548 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4550 * stime.c, stime.h: use SCM_P method.
4552 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4554 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4555 be given at least two arguments. Insist that lst's last element
4556 be a list, but don't make any requirements of its predecessors.
4558 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4560 * eval.c (scm_nconc2last): Revert last change; there seems to be
4561 other stuff going on here.
4563 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4565 * eval.c (scm_nconc2last): Make sure that each element of lst
4566 (which is a list of argument lists, except for the tail) is a
4567 proper list, i.e., finite and terminated by '().
4569 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4571 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4574 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4575 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4578 * vectors.c (scm_make_vector): Fill vectors with the undefined
4579 value, to help make Guile Scheme code more portable to other
4582 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4583 * symbols.h, tags.h: Doc fixes.
4585 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4587 * async.c (scm_take_signal): Doc fixes.
4589 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4591 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4592 want to subtract it from the modulus; we just want to leave it
4595 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4597 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4600 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4602 * throw.c (scm_catch_apply): Finished implementation of
4605 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4607 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4609 (scm_init_filesys): set "i/o-extensions" feature.
4612 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4614 * Makefile.in (root.o): Correct dependencies.
4616 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4618 * Makefile.in: Added dependency entry for root.o.
4620 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4621 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4623 * init.c (scm_start_stack): Set initial root continuation number
4626 * procs.c: New function: scm_thunk_p.
4628 * procs.h: Added declarations of scm_thunk_p.
4630 * root.c: Renamed `call-with-new-root' -->
4631 `call-with-dynamic-root'.
4632 (cwdr): Removed allocation of new root state. This should be done
4633 separately by use of scm_make_root.
4634 (scm_apply_with_dynamic_root): New function: Does what it
4635 sounds like. Needed when spawning threads.
4637 * root.h: Added member last_debug_frame to root state.
4638 Added #include "libguile/debug.h"
4640 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4641 arguments. The motivation is that code in root.c needs catch
4642 functionality, and we want to avoid code duplication.
4643 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4644 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4645 handlers that run without popping the stack into the dynwind
4648 * throw.h: Added prototypes for scm_catch_apply and
4651 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4653 * root.h (scm_root, scm_set_root): Decouple thread support details
4654 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4655 SCM_SET_THREAD_LOCAL_DATA.
4657 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4658 and tortoise scanning loop.
4660 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4662 * Makefile.in: Rebuild dependencies.
4664 * libguile.h: #include "libguile/print.h" before "smob.h", since
4665 the latter uses the print_state structure.
4667 * throw.c (scm_ithrow): Use the correct variable when checking to
4668 see if a given element of scm_dynwinds is a valid catch.
4670 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4671 structure, abort; don't just silently ignore the garbage.
4673 * _scm.h: #include "print.h" here, since it seems to be used just
4675 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4676 strports.c, unif.h: Don't #include "print.h".
4678 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4680 * feature.h (scm_loc_features): Removed external declaration.
4681 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4683 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4685 * feature.c (scm_init_feature): Added threads feature (needs to be
4686 initialized here, since features doesn't exist when
4687 scm_init_threads is called).
4689 * libguile.h: Added #include "libguile/../threads/threads.h".
4690 (This is a kludge to get thread support working. This should be
4693 * configure.in, acconfig.h: Added flags for thread support.
4695 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4698 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4699 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4702 * _scm.h: Added conditional #include "threads.h"
4704 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4705 SCM_THREADS_SWITCHING_CODE.
4707 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4708 allocate the basic dynamic root object.
4709 (scm_boot_guile): Added call to scm_init_root.
4711 * root.c, root.h: Added root smob.
4712 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4713 functions: Implements dynamic roots mostly according to spec in
4714 SCM manual. Main difference is that the second argument is a
4715 throw handler rather than an error "thunk".
4717 * root.h: Added declaration of scm_init_root.
4719 * root.c: Added #include "genio.h", #include "smob.h", #include
4720 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4722 (scm_init_root): Added #include "root.x".
4724 * throw.c: Added #include "stackchk.h"
4725 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4726 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4727 can be used in scm_call_with_new_root; Added reenabling of stack
4728 checking when catching a throw.
4730 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4732 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4734 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4735 element is not found, as per R4RS.
4737 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4739 * list.c: Doc fixes throughout.
4741 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4743 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4744 declare the char * to be const. Avoids a warning in rgx.c.
4746 * ports.h: spelling fix.
4748 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4751 * load.c (scm_sys_try_load_path): throw an error if file not found
4752 (like it says it in NEWS).
4754 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4756 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4757 PROPS slot to '(), not #f; it's an empty alist.
4759 * throw.h, throw.c: Use SCM_P instead of #if hair.
4761 Remove special support for uncaught throws; see throw.c for
4763 * throw.c (uncaught_throw): New function.
4764 (scm_ithrow): Call uncaught_throw if we don't find a throw
4765 target; don't mess with scm_bad_throw_vcell.
4766 (scm_bad_throw_vcell): Variable deleted.
4767 (scm_init_throw): Don't initialize it.
4769 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4772 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4774 * numbers.c (scm_istr2int): If the number is short (as most
4775 numbers are), just call scm_small_istr2int to deal with it.
4776 (scm_small_istr2int): New function, created by un-#ifdefing the
4777 non-bignum version of scm_istr2int and renaming it.
4779 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4781 * load.c (scm_sys_try_load): don't check whether value returned
4782 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4783 Change the Scheme name from %try-load to primitive-load.
4785 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4786 Can avoid passing a message, allowing it to be derived in the
4787 error handler (e.g., if we want to throw to the key both from
4790 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4792 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4793 references now have a new appearance which is more compact and
4794 also gives a clue about what the target of the reference is.
4795 By setting parameters in the print state, more fancy printing can
4796 be achieved. This is used by the (not yet commited) backtrace
4799 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4801 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4804 * print.c: Added #include "struct.h". Removed function
4807 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4808 scm_iprin1. Removed prototype for scm_prlist.
4810 * arbiters.c (prinarb),
4811 async.c (print_async),
4812 debug.c (prindebugobj, prinmemoized),
4813 eval.c (prinprom, prinmacro),
4814 filesys.c (scm_fd_print, scm_dir_print),
4816 mallocs.c (prinmalloc),
4817 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4818 smob.h (scm_smobfuns),
4819 srcprop.c (prinsrcprops),
4821 unif.c, unif.h (scm_raprin1, rapr1),
4822 variable.c (prin_var): Changed argument `int writing' to
4823 `scm_print_state *pstate'.
4825 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4826 that it will be called before scm_init_print.
4828 * print.c (scm_prin1): Print states are now allocated when calling
4829 scm_prin1 and then passed around to all printing functions as an
4830 argument. A cache `print_state_pool' enables reuse of print
4832 (scm_make_print_state): New function.
4833 (scm_iprin1): Adaption to print states.
4834 (scm_iprlist): An initial "hare and tortoise" scan brings down
4835 time complexity to O (depth * N). (Better time complexity will be
4836 achieved when the printing code is completely rewritten.)
4838 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4840 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4841 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4842 it gets done whether or not the cache variable has a value.
4844 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4846 Distinguish #f and ().
4847 * __scm.h: #undef SICP.
4848 * pairs.h (SCM_EOL): Delete this definition, equating it with
4850 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4851 the value it used to have. Doc fixes, too.
4853 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4855 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4856 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4857 Lord's implementation of structs, allowing for tail arrays as
4858 described in the manual. Also fixed some bugs. (Both the interface
4859 and the implementation should be improved.)
4861 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4863 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4864 People who whish to see the source can do `(print-enable 'source)'.
4865 Removed #ifdef DEBUG_EXTENSIONS.
4867 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4869 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4870 integer (assuming for now accepting an integer is a good thing).
4872 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4873 %S will be used instead for write'ing arguments.
4875 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4876 asserts. fix a few other asserts.
4877 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4878 scm_uniform_vector_ref, scm_array_set_x,
4879 scm_dimensions_to_unform_array): change args in
4880 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4881 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4882 scm_substring_fill_x): likewise.
4883 gsubr.c (scm_gsubr_apply): likewise.
4884 eval.c (SCM_APPLY): likewise.
4886 * eval.c (4 places): replace scm_everr with lgh_error or
4889 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4890 scm_memory_error): new procedures.
4891 scm_everr: deleted. can use scm_wta, dropping first two args.
4892 scm_error: convert NULL subr to SCM_BOOL_F.
4894 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4897 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4900 * error.c, error.h: new error keys: scm_arg_type_key,
4901 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4903 scm_wta: reimplement using lgh_error instead of scm_everr.
4905 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4907 * gdbint.c: scm_lread now has one more argument.
4909 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4910 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4911 loading source from non-file ports, which, e. g., happens when
4912 using the Emacs interface).
4914 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4917 * read.c: Added code for recording of positions of source code
4918 expressions; New functions: recsexpr, scm_lreadrecparen;
4919 _scm_make_srcprops --> scm_make_srcprops
4920 (scm_flush_ws): Removed updating of positions counters. This work
4921 is already done by scm_gen_getc
4923 * read.h: Added prototype for scm_lreadrecparen
4925 * print.c: Added #include "alist.h"
4927 * eval.c: Added #include "hash.h"
4929 * eq.c: Added #include "ramap.h"
4931 * options.c: Documentation fixes.
4933 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
4934 (scm_init_srcprop): Adjusted size of initial source-whash. Name
4935 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
4936 --> scm_make_srcprops
4938 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
4939 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
4940 function calls in the definition of the whash access macros.
4942 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
4944 * init.c (scm_boot_guile): Add level of indirection to
4945 scm_boot_guile_1() to ensure that stack base pointer is properly
4946 initialized. There was no guarantee that variable i was the
4947 highest/lowest variable on stack (i.e. the call frame of
4948 scm_boot_guile was not completely protected from gc).
4950 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
4952 * ports.h (scm_port_table): put back file_name, it will be used to
4953 support debugging. Undo related changes in fports.c, ioext.c,
4956 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4958 * ports.h (scm_port_table): remove file_name member for now, it seems
4960 * fports.c (scm_open_file): don't set file_name in PTAB.
4961 (prinfport): don't use file_name in PTAB.
4962 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
4963 * ports.c (scm_add_to_port_table): don't intialize file_name.
4964 (scm_port_file_name): remove for now.
4965 * gc.c (scm_gc_mark): don't mark PTAB file_name.
4967 * fports.h (scm_mkfile): prototype deleted.
4968 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
4970 * debug.c, unif.c: use scm_out_of_range instead of
4971 wta for range errors (ASSERT still needs work).
4973 * error.c, error.h (scm_out_of_range): new procedure.
4975 * error.c, error.h (scm_out_of_range_key): new key.
4977 * posix.c (scm_sync): #else was missing.
4979 * error.c, error.h: append _key to names scm_num_overflow and
4982 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
4983 of consing an empty list.
4984 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
4985 of macros, saves code and string space.
4986 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
4987 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
4988 lower case. Rename scm_syserror_m to scm_syserror_msg.
4989 error.h: prototypes for new procedures.
4991 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
4993 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
4995 * error.c, error.h: setup scm_num_overflow key.
4997 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
4998 Remove definition of SCM_OVSCM_FLOW.
5000 * fports.c (scm_open_file): use SCM_SYSERROR_M.
5002 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
5003 explicit message and args.
5005 * error.c, error.h, __scm.h: change system_error_sym to
5008 * error.c (system_error_sym): remove leading %% from the Scheme name
5011 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
5013 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5015 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
5016 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
5017 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
5018 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
5019 renamed. (These were introduced by unsupervised name
5022 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5024 * print.c: Added code for detection of circular references during
5025 printing. (init_ref_stack, grow_ref_stack): New functions. Added
5026 a hook for printing of closures (accessible via print options).
5027 This leads to a split of calls to scm_iprin1 into two classes:
5028 elementary print operations (e. g. the code which prints a smob)
5029 still use scm_iprin1 while top level calls (like scm_display) use
5030 scm_prin1. scm_prin1 begins by clearing the data structure used
5031 to record reference information.
5033 * print.h: Added declarations of scm_prin1 and scm_prlist.
5035 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
5037 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
5039 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
5041 * error.c (err_head): scm_iprin1 --> scm_prin1
5043 * debug.c: Adjusted header comment.
5047 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
5049 * strerror.c: Doc fix.
5051 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5053 * gdbint.c (gdb_read): Now possible to run during GC.
5054 (unmark_port, remark_port): New functions.
5056 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
5058 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
5059 of allocating a new string object. Also, increase size by
5060 the factor 2 instead of 1.5.
5062 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
5064 * __scm.h (SCM_P): Corrected to run under traditional C.
5066 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
5069 * async.c: Calls to scm_sysintern corrected.
5071 * async.h (scm_async_clock): Redundant declaration removed.
5073 * continuations.c (scm_dynthrow): Redundant declaration removed.
5075 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
5076 Definition typos corrected.
5078 * debug.h: Missing declarations of functions in debug.c added
5081 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
5082 Missing declarations to functions in eval.c added.
5084 * filesys.c: Possibly uninitialized variable rv.
5086 * gc.h (scm_object_addr, scm_unhash_name): Missing
5087 declarations of functions defined in gc.c added.
5089 * genio.c: Possible typos str_data -> wstr_data. ???
5091 * genio.c: Possibly unintended shadowing of local variable
5092 `int c' (gotos out of scope of inner `c'). ???
5094 * init.c: Uninitialized `SCM last' may be used.
5096 * ioext.h: (scm_sys_isatty_p): Typo.
5098 * list.h (scm_list_head): Missing prototype for function in
5101 * numbers.c (scm_two_doubles): Changed from extern to static
5102 (is used only within numbers.c).
5104 * numbers.h: Repeated declarations removed.
5106 * ports.h (scm_close_all_ports_except): Declaration for the
5107 function defined in ports.c added.
5109 * posix.h: Missing declarations added.
5111 * procs.h (scm_make_subr_opt): Missing declaration added.
5113 * socket.h (scm_sys_gethost): Missing declaration added.
5115 * socket.h: Redundant declarations removed (they are in fdsocket.h).
5117 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
5118 Missing declarations added.
5120 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
5122 * struct.c: Uninitialized variable `SCM answer' may be used.
5124 * unif.c (l2ra): Declaration prototype.
5126 * unif.c (scm_array_equal_p): Dummy definition removed (it is
5127 defined in ramap.c).
5129 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
5130 Redundant declarations removed (they are in ramap.h).
5132 * variable.h (scm_make_udvariable,
5133 scm_make_undefined_variable): Declaration corrected to
5134 correspond variable.c.
5136 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
5137 Missing declarations added.
5139 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5141 * Makefile.in (distclean): Don't forget to delete fd.h.
5143 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5145 * fd.h.in, tags.h: Trivial cleanups.
5147 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5148 marksweep.h just declared functions from gc.c.
5149 * gc.h, libguile.h: Don't #include "marksweep.h".
5150 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5151 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5152 dependencies updated.
5154 * libguile.h: Don't #include "files.h"; it's been deleted.
5156 * files.c (scm_sys_delete_file): Moved to filesys.c.
5157 File is now empty; deleted.
5159 * filesys.c: scm_sys_delete_file is now here. Remove
5160 #if's; they seem to rely on remnants of an old portability
5161 regimen. If the problems come up again, solve them properly,
5162 using autoconf. Specifically: Don't test M_SYSV, and #define
5163 remove to be unlink if it's #defined; don't use remove just
5164 because HAVE_STDC_HEADERS is #defined.
5165 * filesys.h: Add declarations for scm_sys_delete_file.
5166 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5167 files.o, files.h, files.c, and files.x.
5168 * init.c: Don't #include "files.h", and don't call scm_init_files.
5170 Use SCM_P instead of PROTO; the latter intrudes on the user's
5172 * params.h: Deleted; definition of SCM_P moved to...
5173 * __scm.h: ... here, where it replaces PROTO macro.
5174 * libguile.h, smob.h: Don't #include "params.h".
5175 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5176 smob.h: Fix prototypes accordingly.
5177 * Makefile.in: Update dependencies.
5178 (inner_h_files): Remove params.h.
5180 * gc.c: #include "gc.h"; every module should include its header,
5181 to let the compiler cross-check the declarations against the
5184 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5185 simpos.h: #include "libguile/__scm.h".
5187 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5189 * init.c: Don't forget to #include smob.h and init.h.
5190 * Makefile.in: Dependencies updated.
5192 * smob.h: Use PROTO instead of #if __STDC__.
5194 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5196 * __scm.h: Doc fixes.
5198 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5199 <angles>; this allows `make depends' to work properly.
5201 * libguile.h: #include smob.h and pairs.h before the others; they
5202 define typedefs used by other headers.
5204 C files should #include only the header files they need, not
5205 libguile.h (which #includes all the header files); the pointless
5206 recompilation was wasting my time.
5207 * Makefile.in (all .o dependency lists): Regenerated.
5208 * libguile.h: Don't try to get a definition for size_t here...
5209 * __scm.h: Do it here.
5210 * _scm.h: Since this is the internal libguile header, put things
5211 here that all (or a majority) of the libguile files will want.
5212 Don't #include <libguile.h> here; that generates dependencies on
5213 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5214 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5215 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5292 * srcprop.c: Get "srcprop.h", "weaks.h", "hashtab.h", "debug.h",
5293 "alist.h", "smob.h".
5294 * stackchk.c: Get "stackchk.h", "genio.h".
5295 * stime.c: Get "stime.h"."libguile/continuations.h".
5296 * strings.c: Get "strings.h", "chars.h".
5297 * strop.c: Get "strop.h", "chars.h".
5298 * strorder.c: Get "strorder.h", "chars.h".
5299 * strports.c: Get "strports.h", "print.h", "eval.h", "unif.h".
5300 * struct.c: Get "struct.h", "chars.h".
5301 * symbols.c: Get "symbols.h", "mbstrings.h", "alist.h",

5305 "dynwind.h", "eval.h", "alist.h", "smob.h", "genio.h".
5306 * unif.c: Get "unif.h", "feature.h", "strop.h", "sequences.h",
5307 "smob.h", "genio.h", "eval.h", "chars.h".
5308 * variable.c: Get "variable.h", "smob.h", "genio.h".

5311 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
5312 * weaks.c: Get "weaks.h".
5314 * stackchk.h: #include "libguile/debug.h",
5316 * print.h, read.h: #include "options.h", since everyone who uses
5317 either of these files will need that.
5319 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5320 anyone who uses this file will need them to define the smob
5321 printing functions. Also, get markers.h, since people will need
5322 to #define the mark functions.
5324 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5325 * ports.h: ... to here.
5327 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5328 don't rely on archaic C default type rules.
5330 * fports.h: #include "libguile/ports.h", since you need that in
5331 order to parse this.
5333 * genio.h: #include "libguile/print.h", because you need that to
5334 parse this; don't bother #including "ports.h", since print.h gets
5337 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5339 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5340 this; it's now a reference to an element of *scm_root.
5342 * debug.h: Don't #include "options.h"; the compiler won't be able
5343 to find that once the headers are installed; instead, #include
5344 "libguile/options.h".
5345 * gc.h: Same, with marksweep.h.
5346 * mbstrings.h: Same, with symbols.h.
5347 * scmhob.h: Same, with _scm.h.
5348 * smob.h: Same, with params.h.
5350 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5351 C files; there's no need for this, and it forces recompilations
5354 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5356 * error.c (scm_error): declare scm_error_callback.
5358 * error.h: prototype for scm_error_callback.
5360 * __scm.h: define lgh_error.
5361 (SCM_SYSERROR): redefine using lgh_error.
5363 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5365 * error.c (scm_error): new procedure.
5367 * error.h: prototype for scm_error.
5369 * Makefile.in (install): install scmconfig.h from the current
5370 directory, not $(srcdir).
5372 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5374 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5375 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5376 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
5377 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
5378 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
5379 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5380 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5381 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5382 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5383 vports.h, weaks.h: #include "libguile/__scm.h", not
5384 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5385 dependencies are within libguile properly.
5387 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5389 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5390 when scmconfig.h doesn't exist.
5392 * load.c (scm_sys_try_load): Correct spelling.
5394 * feature.c (scm_loc_features): Make this static.
5396 * Makefile.in (libpath.h): Omit trailing slash from path. We
5397 shouldn't require it of users, so why put it here?
5399 Move code to initialize and search %load-path from ice-9 to C
5400 code, so we can use the load-path to find the ice-9 boot code;
5401 this makes it easier to run Guile without installing it. See
5402 corresponding changes in guile/Makefile.in.
5403 * feature.c: Move stuff concerned with the load path to load.c.
5404 (scm_compiled_library_path): Deleted.
5405 Don't #include libpath.h here.
5406 * feature.h: Don't mention scm_compiled_library_path.
5407 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5408 <sys/stat.h>, and <unistd.h> (if present).
5409 (R_OK): #define if the system hasn't deigned to.
5410 (scm_loc_load_path): New variable.
5411 (scm_init_load_path, scm_sys_search_load_path,
5412 scm_sys_try_load_path): New functions.
5413 (scm_init_load): Initialize scm_loc_load_path to point to the
5414 value cell of the Scheme %load-path variable.
5415 * load.h: Add declarations for scm_sys_search_load_path,
5416 scm_sys_try_load_path.
5417 * init.c: Call scm_init_load_path.
5418 * Makefile.in (feature.o, load.o): Dependencies updated.
5420 * load.c, load.h: Rewrite using PROTO macro.
5422 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5424 * gc.c (scm_cellp): New function: C predicate to determine if an
5425 SCM value can be regarded as a pointer to a cell on the heap.
5427 * gc.h: Added declaration of scm_cellp.
5429 * gdb_interface.h: New file: The GDB interface header from the GDB
5432 * gdbint.c: New file: GDB interface.
5434 * gdbint.h: New file: GDB interface.
5436 * libguile.h: Added #include <libguile/gdbint.h>.
5438 * init.c (scm_boot_guile): Added scm_init_gdbint.
5440 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5441 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5442 found if object files and source are kept separate).
5444 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5446 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5448 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5450 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5451 TK_SRC_DIR; they're not relevant any more.
5453 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5454 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5456 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5458 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5459 search path, so we can find the <libguile/MUMBLE.h> headers.
5461 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5463 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5464 implicit in the .c.o rule.
5465 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5468 Put the library path in a header file, instead of passing it on
5469 the command line in every compilation.
5470 * Makefile.in (libpath.h): New target.
5471 (feature.o): Depend on libpath.h.
5472 (clean): Delete libpath.h.
5473 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5474 * feature.c: ... #include "libpath.h" here.
5475 * .cvsignore: Ignore libpath.h.
5477 Don't install the unwashed masses of Guile header files in the
5478 main #include path; put most of them in a subdirectory called
5479 'libguile'. This avoids naming conflicts between Guile header
5480 files and system header files (of which there were a few).
5481 * Makefile.in (pkgincludedir): Deleted.
5482 (innerincludedir): New variable; this and $(includedir) are enough.
5483 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5484 (installed_h_files): Divide this up. Now this variable lists
5485 those header files which should go into $(includedir) (i.e. appear
5486 directly in the #include path), and ...
5487 (inner_h_files): ... this new variable says which files appear in
5488 a subdirectory, and are referred to as <libguile/mumble.h>.
5489 (h_files): List them both.
5490 (install): Create innerincludedir, not pkgincludedir. Put
5491 the installed_h_files and inner_h_files in their proper places.
5492 (uninstall): Corresponding changes.
5493 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5494 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5495 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5496 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5497 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5498 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5499 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5500 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5501 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5502 vports.h, weaks.h: Find __scm.h in its new location.
5503 * __scm.h: Find scmconfig.h and tags.h in their new locations
5504 (they're both "inner" files).
5506 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5508 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5510 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5512 * posix.c: Doc fixes.
5514 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5516 * socket.c: Don't include a prototype for inet_aton; just use a
5517 K&R style declaration, to avoid warnings but minimize the chance
5518 of conflicts with the system.
5520 On NextStep, <utime.h> doesn't define struct utime, unless we
5521 #define _POSIX_SOURCE before #including it.
5522 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5523 * acconfig.h: New comment text for above CPP symbol.
5524 * configure.in: Call it.
5525 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5527 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5529 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5530 testing for __EMX__.
5532 * posix.c: #include <libc.h>, if it exists.
5534 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5535 don't even know if the latter exists.
5537 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5538 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5539 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5541 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5543 (scm_init_posix): Use them when initializing the Scheme constants
5546 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5548 * Makefile.in (libdir, includedir, bindir): Use the
5549 autoconf-supplied values, instead of deriving them ourselves.
5550 (pkgincludedir, datadir, pkgdatadir): New variables.
5551 (install, uninstall): Put the header files in a special
5552 subdirectory, not in the main search path.
5554 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5555 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5557 * Makefile.in (IMPLPATH): Deleted; never used.
5559 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5560 on the Tcl/Tk source any more.
5561 (INCLUDE_CFLAGS): Remove references to the above.
5563 * Makefile.in (version.o): Corrected dependencies.
5565 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5567 * libguile.h: #include "version.h"
5569 * init.c (scm_boot_guile): Call scm_init_version.
5570 * gscm.c (gscm_run_scm): Call scm_init_version.
5572 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5573 GUILE_VERSION): AC_DEFINE these.
5574 (acconfig.h): #undef the above symbols.
5576 * Makefile.in (libobjs): Add version.o.
5577 (installed_h_files): Add version.h.
5578 (c_files): Add version.c.
5579 (gen_c_files): Add version.x.
5580 (version.o): New rule.
5581 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5582 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

5590 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5591 weaks.o): Add version.h to dependency lists.
5592 (markers.o): Remove duplicate rule.
5594 * version.h: New file.
5596 * version.c: New file.
5598 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5600 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5601 array; use it appropriately. Since GCC is quite happy to
5602 subscript functions, it never warned us about this; we should use
5603 -Wpointer-arith in the future. I guess we never tested
5606 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5608 * socket.c: Doc and copyright fixes.
5610 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5612 * debug.c: Fixed and improved gdb support.
5614 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5616 * socket.c: Added declaration of inet_aton to avoid compiler
5617 warning. (Hope this solution is correct.)
5619 * stime.c: Added declaration of ftime. (This is missing in
5622 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5624 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5626 * Makefile.in (c_files): add strerror.c.
5628 * strerror.c: new file from Emacs' sysdep.c.
5629 maybe configure should also check for sys_errlist.
5631 * configure.in (AC_REPLACE_FUNCS): add strerror.
5633 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5635 * debug.c (scm_init_debug): Added initialization for
5636 scm_evaluator_traps.
5638 * debug.h, debug.c: Various name changes.
5639 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5640 "debug-options-interface". See commentary in options.c.
5642 * options.h, options.c: Options now have documentation strings.
5643 Also added a long explanatory commentary.
5645 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5648 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5649 last_debug_info_frame is now updated in all cases.
5651 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5654 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5656 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5657 Added option STACK_CHECKING.
5659 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5661 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5663 * __scm.h: Removed symbols for debugging support.
5665 * acconfig.h: Added symbols for debugging support.
5667 * configure.in: Added user option for debugging support.
5668 --enable-debug will include the debugging code into libguile.a.
5670 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5671 scm_relocate_chunk_to_heap.
5673 * debug.c: New file: low-level debugging support. It also
5674 includes support for debugging with gdb. (The extensions to gdb
5675 are written by Per Bothner at Cygnus.)
5677 * debug.h: New file: low-level debugging support.
5679 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5680 argument pairs. Extensive modifications to the debugging
5681 evaluator. Added "SECTION:" commentaries to clarify what happens
5682 when, during double compilation. Renamed EVALIMP --> EVALIM.
5683 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5684 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5685 the beginning of the file. New procedure: scm_unmemocopy.
5686 Added some global state variables needed by the debugging
5687 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5688 check_entry, check_apply, check_exit, debug_options and
5689 evaluator_traps. New acro: undefine.
5691 * eval.h: Renamed EVAL --> XEVAL.
5693 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5694 --> scm_make_weak_key_hash_table.
5696 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5697 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5699 * libguile.h: Conditionally include debug.h
5701 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5702 scm_object_properties shouldn't return handle. `handle' now gets
5703 initialized in scm_set_object_properties_x. scm_object_properties
5704 doesn't any longer create an entry in scm_object_whash.
5706 * options.c: New file: handling of run time options.
5708 * options.h: New file: handling of run time options.
5710 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5712 * print.c: New procedure: scm_print_options
5714 * print.h: Defines for print options.
5716 * read.c: New procedure: scm_read_options
5718 * read.h: Defines for reader options.
5720 * root.h: Added scm_source_whash among scm_sys_protects.
5722 * srcprop.c: New file: source properties.
5724 * srcprop.h: New file: source properties.
5726 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5727 (Bug found by A. Green.)
5729 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5731 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5733 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5735 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5737 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5738 and should be called by the final client.
5740 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5742 * gc.h: Use the PROTO macro when declaring functions.
5743 * gc.c: Use the PROTO macro when declaring static functions.
5744 Remove the CPP hair around function definitions.
5746 * gc.c (scm_init_storage): Initialize scm_asyncs.
5748 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5749 preprocessor symbol; "__scm.h" is where it might get #defined.
5750 * __scm.h: Similar: #include <scmconfig.h> before testing
5753 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5755 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5757 * init.c (scm_boot_guile): Add init_func argument; call
5758 (*init_func) instead of calling scm_appinit; it's ucky to
5759 hard-code names for the user's procedures.
5760 * init.h (scm_boot_guile): Adjust declaration.
5762 * __scm.h (PROTO): New macro, for declaring functions with
5765 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5766 eliminate all the __STDC__ conditionals.
5767 (scm_boot_guile): Add declaration.
5768 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5769 Remove __STDC__ conditionals around function definitions; the
5770 declarations in init.h will provide the same information, more
5773 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5774 complain about it in the error message; the error message is
5775 adequate without that note, and there's nothing the user can do
5778 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5780 * Makefile.in (ancillary): Drop def.sed.
5782 * posix.c (scm_init_posix): Use numeric values, rather than
5783 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5784 F_OK. The symbols aren't available on some systems, and I'm
5785 pretty sure their values are fixed by common widespread practice.
5786 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5788 More functions unavailable on some systems.
5789 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5790 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5792 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5793 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5794 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5795 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5796 stub that signals an error as the #else.
5798 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
5800 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>

5831 genio.c, simpos.c, vports.c: include string.h.
5833 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
5835 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
5837 (scm_addr_buffer_size): change type from scm_sizet to int.
5838 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
5839 from scm_sizet to int.
5841 * error.c: include unistd.h.
5843 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
5846 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
5848 * __scm.hd, def.sed: deleted.
5850 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
5852 Changes for NeXT, suggested by Robert Brown.
5853 * configure.in: Call AC_TYPE_MODE_T.
5854 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
5855 NeXT. Put header file list in alphabetical order.
5856 * configure, scmconfig.h.in: Regenerated.
5857 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
5859 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
5862 * acconfig.h: New file, providing documentation for the CPP
5863 symbols defined in configure.in
5864 * acconfig-1.5.h: Removed; superceded by the above.
5866 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
5868 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
5870 * fports.c (scm_open_file): don't return #f, throw error.

5879 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
5881 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
5883 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
5885 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
5887 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5889 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5890 This is necessary on Ultrix, and doesn't hurt portability.
5892 * Makefile.in (dist-dir): New target, implementing a new dist system.
5893 (installed_h_files): Put in alphabetical order.
5894 Remove duplicate entries for markers.h and unif.h.
5895 (c_files): Remove duplicate entries for markers.c.
5896 (ancillary): Renamed from anillery; all uses changed. Remove
5897 PLUGIN; it's a directory, and needs special treatment in dist-dir.
5898 Remove all the ../doc/* files; doc/Makefile.in handles that.
5900 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5902 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5903 every if must have an else, or else the whole command has a
5904 non-zero exit code whenever the if's condition is false.
5906 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
5908 * posix.c: include string.h.
5910 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>

5915 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
5916 Remove leading % from scheme names.
5917 Do not return error values, call SCM_SYSERROR or similar.

5921 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
5923 * struct.c (scm_init_struct): new file.
5925 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
5927 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
5928 (scm_list_head): added list-head for rapidly chopping argument
5929 lists off of longer lists (and similar).

5934 handle for obj, not the handle itself.
5936 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
5938 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
5939 weak hash tables last of all marking to avoid an obscure gc bug.
5940 WARNING: circular lists stored in a weak hash table will hose us.
5942 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
5944 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):

5959 * strports.c (scm_strprint_obj): convenience function. C for
5960 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))

5966 Initialization specific to tcl interpreters removed.
5968 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
5970 * ports.c (scm_ports_prehistory): size malloced here doesn't
5971 matter so long as it is non-0 (got rid of "* 4").
5973 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
5975 * gscm.h: gscm_mkarray eliminated (presumably was not being used
5976 since its definition was bogus).
5978 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
5980 * mallocs.[ch]: back again (for rx at least).
5982 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
5984 * ports.c: removed functions relating to the mapping between ports
5985 and descriptors. (That stuff is unix-specific and should be collected
5986 in a separate library).
5988 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
5989 (Tom Mckay@avanticorp.com)
5991 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
5993 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
5994 handled correctly (SCM_FREEP was applied to them) -- test for
5995 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
5996 being overwritten with #f. (brown@grettir.bibliotech.com)

6040 (possibly triggering gc) before setting the tag of the corresponding
6043 * pairs.c (scm_delq_x): never throw an error.
6045 * vectors.c (scm_make_vector): made the default vector fill argument
6046 into '() (much more useful than the previous value, "#unspecified")

6050 * ports.c (scm_add_to_port_table): Added fields
6051 to port table entries: file_name, line_num, col.
6052 Update these in open_file, gen_getc and gen_ungetc.
6053 Added procedures to access those fields.
6055 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
6057 * procs.c (scm_make_subr_opt): new entry point for making

6090 This file is for stuff relating specifically to Scheme libraries
6093 * eval.c (scm_m_define): don't give warning about redefinition, don't
6096 NOTE: this should throw a resumable exception with parameters --
6097 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?

6121 because it changes size.
6123 (stputc stwrite): check/change the strings length with interrupts
6126 * objprop.c (scm_set_object_property_x &c): use the generic
6127 hashing functions and be threadsafe.

6163 initialization to fix a race condition.
6165 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

6189 set the multi_byte flag correctly in symbols. This is wrong.
6190 intern_obbary_soft and msymbolize should take an extra parameter.
6191 Also, weird multibyte symbols don't print correctly.
6192 The weird symbol syntax is also a bit bogus (emacs doesn't quite
6195 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
6197 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means
6198 use the system symhash. == #t means create an uninterned symbol.
6200 Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>
6202 * strings.c (scm_make_shared_substring): build'em.
6203 It might better to keep a table of these and use one

6274 * lvectors.c (scm_get_lvector_hook):
6275 In guile-ii, the lvector code was broken. It was fixed in guile-iii.
6276 It seems to me like if it is broken again in guile-iv...Here is a patch.

6290 Give a warning, not an error, for unrecognized modes.
