3 * script.c (scm_compile_shell_switches): Add handling of -q switch
4 (inhibit loading of user init file).
5 (scm_shell_usage): Add usage text for -q switch.
6 (scm_compile_shell_switches): Always load user init file first if
9 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
11 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
12 and is now broken under NetBSD. I can't fathom what it's trying
13 to do, so I've replaced it with something that I do understand,
14 which seems to work, and which isn't broken on NetBSD. "Progress?
15 You Decide." (Thanks to Perry Metzger.)
17 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
18 signed/unsigned comparison.
20 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
22 Warning fixes from Greg Harvey:
23 * unif.c (scm_array_set_x): initializer for pos
24 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
25 * struct.c (scm_struct_ref, scm_struct_set_x): Added
26 initializers for field_type, since EGCS so desparately wants to
28 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
29 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
30 when GUILE_DEBUG is defined.
31 * dynwind.h (scm_wind_chain): Same.
32 * ports.h (scm_pt_size, scm_pt_member): Same.
33 * print.h (scm_current_pstate): Same.
34 * procs.h (scm_make_cclo): Same.
36 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
38 Handle short and long long uniform arrays properly. (Thanks to
40 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
41 raeql_1): Add cases for scm_tc7_svect (short vectors) and
42 scm_tc7_llvect (long long vectors).
44 Change the way libguile and boot-9.scm are timestamped, to try to
45 get rid of these spurious mismatch warnings. Now both
46 libguile/versiondat.h and ice-9/version.scm are generated directly
47 by the configuration process, rather than having version.scm
48 generated directly, and libguile/versiondat.h generated by the
49 Makefile, which is generated by configure. It seems that
50 sometimes the Makefile would change, but versiondat.h depends on
51 Makefile.in, not Makefile, so it wouldn't get rebuilt.
52 * Makefile.am (versiondat.h): Target removed; this is generated
53 directly by the configure script now.
54 (BUILT_SOURCES): Remove versiondat.h.
55 * versiondat.h.in: New file, transformed by the configure script
57 * Makefile.in: Regenerated.
59 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
60 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
61 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
62 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
63 if we want to use them in a header file some day, we can. (Thanks
66 * stime.c (scm_get_internal_real_time): Do the arithmetic using
67 SCM numbers, so we won't have rollover problems; the range of a
68 signed long in milliseconds is about 25 days. (Thanks to Karl
71 Don't redefine sleep and usleep; fix this problem now.
72 * coop.c (sleep, usleep): Remove declarations; we don't use or
73 redefine these any more.
74 (scm_thread_usleep, scm_thread_sleep): New functions which do the
75 job of usleep and sleep in a thread-friendly way. We can use
76 these in the rest of Guile. Define versions for systems both with
78 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
79 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
80 we're just using it, not redefining it, we can use a K&R style
82 (sleep): Declare this, too, if the system hasn't.
83 (scm_sleep, scm_usleep): Use scm_thread_sleep and
84 scm_uthread_sleep if they're available; otherwise, just call the
86 * scmconfig.h.in: Regenerated.
88 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
90 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
92 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
96 The argument type of usleep varies from system to system,
97 as does the return type. We really shouldn't be redefining usleep
98 at all, but I don't have time to clean that up before the 1.3.
99 release. It's on the schedule for afterwards. (Thanks to Julian
101 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
103 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
104 * scmconfig.h: Regenerated.
106 * simpos.c (scm_software_type): Procedure deleted. This isn't the
107 right way to handle system variation. Autoconf's approach is the
109 * simpos.h (scm_software_type): Declaration deleted.
111 * script.c (scm_find_executable): Don't test if unix is #defined
112 here; first, NetBSD doesn't #define it, and second, it's the wrong
113 way to go about these things. (Thanks to Perry Metzger.)
114 (dld_find_executable): Delete this MSDOS support code. This isn't
115 the way we want to support this; it needs to be rethunk at a
118 * genio.c (scm_do_read_line): Don't just politely check that the
119 line was either non-empty or EOF. Abort if it's empty and not
122 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
124 * scmconfig.h.in: Regenerated.
126 * libguile.h: Don't omit the dynamic linking functions. (Thanks
129 * genio.c (scm_do_read_line): Count lines correctly when the file
130 doesn't end in a newline.
132 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
134 * genio.c (scm_do_read_line): Maintain the line count correctly.
135 (Thanks to Harvey J. Stein and Greg Harvey.)
137 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
140 * numbers.c (big2str): Protect t from garbage collection until
141 we're done. (Thanks to Gary Houston.)
143 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
145 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
147 * Makefile.in: Regenerated.
149 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
150 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
153 Do magic to mix reads and writes on stdio FILE-based ports.
154 (Thanks to Christian Lynbech.)
155 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
157 (pre_read, pre_write): New functions.
158 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
159 local_fputs): Call them.
160 (local_fflush): Mark the port as ready for reading and writing.
161 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
162 flags on new port objects. This might not be accurate --- who
163 knows what state the FILE * is in when we get it --- but it won't
164 do extraneous calls to fflush or fseek, so it's no worse than the
165 behavior before this change.
166 * ports.h: Add comment.
168 Centralize the creation of port objects based on stdio FILE * in
169 fports.c; don't just throw them together anywhere.
170 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
171 what the rest of Guile wants. Don't set the revealed count;
172 that's only appropriate for stdin, stdout, stderr.
173 (scm_standard_stream_to_port): This function does set the revealed
175 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
176 not scm_stdio_to_port.
177 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
178 * fports.c (scm_open_file): Same.
179 * posix.c (scm_pipe): Same.
180 * socket.c (scm_sock_fd_to_port): Same.
181 * ioext.c (scm_fdopen): Same.
182 (scm_freopen): Moved from here to...
183 * fports.c (scm_freopen): ... here. This is really something that
184 munges the internals of an fport, so it should go here.
185 * fports.h (scm_stdio_to_port): Adjust prototype.
186 (scm_standard_stream_to_port, scm_freopen): New protoypes.
187 * ioext.h (scm_freopen): Prototype removed.
189 * filesys.c (set_element, get_element): This can work on both pipe
190 and file ports, so use SCM_FPORTP to typecheck, instead of testing
193 * scmconfig.h.in: Regenerated.
195 Change the definition of the functions in scm_ptobfuns so that
196 they get passed the port object, not the port's stream.
197 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
198 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
199 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
200 Pass the port itself to the scm_ptobs function.
201 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
202 scm_generic_fgets): Same.
203 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
204 getc_void_port, fgets_void_port, close_void_port): Just change the
205 argument names; these functions don't really do anything.
206 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
207 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
208 port as an argument, and use SCM_STREAM to get the stdio FILE *.
209 Also, use prototyped definitions, and get rid of the extra
211 (scm_fptob, scm_pipob): We don't need casts here any more.
212 * strports.c (prinstpt): Use prototype declarations.
213 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
214 and use SCM_STREAM to get the string info. Also, use prototyped
215 definitions, and get rid of the extra declarations.
216 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
219 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
220 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
222 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
223 scm_fgets, for consistency.
224 (scm_fptop, scm_pipob): References updated.
226 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
228 Include the source location in error messages for scripts.
229 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
230 stack is still there when we catch the error.
231 * throw.c (handler_message): If we are handling an error with a
232 message, then put together the proper arguments and call
233 scm_display_error, instead of scm_display_error_message. That
234 displays source location, if it can find it.
236 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
238 * gc.c (scm_unprotect_object): Change this so that calls to
239 scm_protect_object and scm_unprotect_object nest properly.
240 (scm_protect_object): Doc fixes.
242 * strings.c (scm_string_set_x): Require the argument to be a
243 writable string, not a substring or a symbol.
244 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
245 (Thanks to John Redford and Charbel Jacquin.)
247 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
249 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
251 * eval.c (safe_setjmp): Remove this misunderstanding.
252 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
255 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
257 * libguile.h: Mark these as C declarations, for compilation by C++
260 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
261 __cplusplus clause. I seriously doubt this ever worked the way
262 the author seems to have intended.
264 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
266 Utterly needless cleanups to hopelessly messy code.
267 * ports.c: Doc fixes.
268 (scm_fflush): Moved to ...
269 * genio.c (scm_fflush): ... here, amongst all the other port
270 method invocation functions.
271 * genio.h, ports.h: The prototype moves too.
273 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
275 * backtrace.c (display_error_body): The current frame does not
276 always have a parent frame; consider a function called directly
277 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
280 * alloca.c (alloca): Undo yesterday's changes, and simply call
281 malloc directly for storage, and abort if we don't get what we
282 want. The situation is much simpler --- just call malloc. Emacs
283 has bizarre/evil requirements (signal handlers might malloc unless
284 you set this global flag, so you have to set the flag around all
285 calls to malloc) which we are certainly not going to conform to,
286 so we can do the simple and obvious thing.
288 * coop.c (coop_condition_variable_wait): Make this function
289 static. It's only useful internally --- you should never just
290 wait on a condition variable.
291 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
293 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
295 * unif.c (scm_array_set_x): Accept any kind of number as an
296 element for a uniform vector of doubles. This is more consistent
297 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
299 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
300 works; I can't conveniently test it myself. (Thanks to Dvid
301 Tillman for the bug report.)
305 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
306 from here, not from scm_compile_shell_switches (which is a pretty
307 dumb place to do it).
308 (scm_load_startup_files): New function.
309 (scm_ice_9_already_loaded): Variable moved to here from script.c.
310 * script.c (scm_compile_shell_switches): Don't load the startup
312 (scm_ice_9_already_loaded): Variable moved.
313 * init.c (scm_load_startup_files): Prototype for new function.
314 * gh_init.c (gh_enter): Doc fix.
316 1998-10-03 <jimb@savonarola.red-bean.com>
318 Some anti-warning changes from Greg Harvey.
319 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
320 warnings when it doesn't understand our NORETURN declarations in
322 * posix.c (scm_mknod): Similar.
324 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
326 * posix.c (scm_getpwuid): If we can't find an entry, return our
327 own message, instead of using scm_syserror --- the getpwMUMBLE
328 functions don't set `errno' to anything interesting.
330 1998-10-03 <jimb@savonarola.red-bean.com>
332 Get rid of warnings from the cooperative threading system.
333 * threads.h (scm_single_thread_p, scm_yield,
334 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
335 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
336 scm_wait_condition_variable, scm_signal_condition_variable): Add
337 prototypes for these Scheme-visible functions.
338 * coop-defs.h (coop_next_runnable_thread,
339 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
340 Prototypes for these here, even though they're from iselect.c.
341 (coop_condition_variable_wait, coop_join): Add prototypes.
342 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
343 scm_threads_free_condvar): Make these smob functions static.
344 * coop-threads.h (coop_init): Give this a real prototype.
345 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
346 (coop_next_runnable_thread): No need to provide prototype; it's in
349 * scmconfig.h.in: .detarenegeR
351 * iselect.c, threads.c: Doc fixes.
353 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
355 * Makefile.in: Regenerated with a patched automake, to get
356 dependency generation right when using EGCS.
358 * inet_aton.c (inet_aton): Add prototype, to remove compiler
359 warning. (Thanks to Robert Pluim.)
361 * inet_aton.c (inet_aton): Reassure the compiler that the
362 arguments to the <ctype.h> macros are all unsigned characters, not
365 1998-10-03 <jimb@savonarola.red-bean.com>
367 Getting rid of more warnings...
368 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
369 today's change to ../configure.in.
370 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
371 * scmconfig.h.in: Regenertaded.de.,.__
372 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
373 (scm_localtime, scm_mktime): Use a const char * to manipulate the
376 * readline.c: Doc fix.
377 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
378 * readline.h (scm_filename_completion_function): Add prototype.
379 (scm_init_readline): Make this into a prototype.
381 * readline.c (scm_filename_completion_function): Use SCM_PROC to
382 declare this, instead of calling scm_make_subr manually.
384 1998-10-02 <jimb@savonarola.red-bean.com>
386 * readline.h (scm_init_readline): Add prototype for this.
387 (scm_init_readline): Make this a real prototype.
389 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
391 Warning fixes from Maciej Stachowiak:
392 * backtrace.h (scm_display_application, scm_backtrace): Add
394 * debug.c (scm_m_start_stack): Make this function static.
395 * fluids.h (scm_fluid_p): Add prototype.
396 * procprop.c (scm_i_procedure_arity): Make this function static.
397 * regex-posix.c (scm_regexp_error_msg): Make this function static.
398 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
399 * root.h (scm_dynamic_root): Add external prototype.
400 * scmsigs.h (scm_usleep): Add external prototype.
401 * script.h (scm_init_script): Use prototype, not K&R decl.
402 * stacks.h (scm_stack_id): Add external prototype.
403 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
405 1998-09-30 Mark Galassi <rosalia@cygnus.com>
407 * gh.h: took out the definitions of vset and vref, since they are
408 replaced by the proper vector routines that correspond to the R4RS
411 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
413 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
414 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
415 third argument, a C expression that should result in a SCM value,
416 which is used to initialize the variable. Reimplemented
417 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
420 * version.h (scm_libguile_config_stamp): Add prototype.
421 (From Maciej Stachowiak.)
423 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
425 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
426 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
428 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
430 * print.c (scm_iprin1): Rather than having one i, and using it in
431 several places, declare a fresh i local to each block where it is
432 used, and give it a signedness appropriate to its use in each case.
435 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
438 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
439 signed/unsigned clashes.
441 * posix.h (scm_tmpnam): Added prototype.
443 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
444 scm_make_subclass_object): Add external prototypes.
446 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
447 comparison is okay here.
449 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
451 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
452 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
454 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
457 * load.c (swap_port): Make this function static.
459 * load.c (scm_search_path): Make max_path_len and max_ext_len
460 unsigned, since they're compared against string sizes.
462 * load.c (init_build_info): Make i unsigned.
464 * ioext.h (scm_read_line): Add prototype.
466 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
467 scm_hash_fn_remove_x): Make hash bucket index local variable k
468 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
469 accurately as possible.
471 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
472 comparisons, and range checking to make sure those casts are
475 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
476 signed/unsigned comparisons.
478 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
479 avoid signed/unsigned comparisons.
480 * smob.h (scm_numsmob): Change extern declaration to match.
482 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
483 avoid signed/unsigned comparisons.
484 * ports.h (scm_numptob): Change extern declaration to match.
485 (scm_current_load_port, scm_set_port_line_x,
486 scm_set_port_column_x): New prototypes.
488 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
489 test code, and it causes warnings.
491 * gh.h (gh_int2scmb, gh_uniform_vector_length,
492 gh_uniform_vector_ref): Added prototypes.
494 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
495 debugging support unconditionally. That's backtrace.c, stack.c,
496 debug.c, and srcprop.c.
497 (EXTRA_libguile_la_SOURCES): Omit those from here.
498 * Makefile.in: Regenerated.
500 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
502 * options.c (scm_options): Bugfix: Allow empty list of options!
504 * debug.c, debug.h (scm_single_step): Removed.
505 (scm_with_traps): New procedure. This procedure could easily be
506 written in Scheme but needs to be highly optimized.
508 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
510 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
511 Check SCM_TRAPS_P before trapping.
513 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
515 Changes to avoid signed/unsigned comparison warnings.
516 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
517 (scm_gc_sweep): Make n and j local to the blocks they're used in,
518 so they can have appropriate types for each application. Make i
519 signed. Use initializers in some spots. I'll probably pay for
521 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
522 (scm_must_realloc): Make nm unsigned.
523 (init_heap_seg): Make new_seg_index and n_new_objects signed.
524 (scm_init_storage): Use prototype-style definition, and make the
526 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
527 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
529 * filesys.c (scm_readlink): Make local vars rv and size ints, to
530 avoid signed/unsigned comparison warnings, and because the return
531 value of readlink may be -1. Don't bother casting the third
532 argument to readlink.
534 * filesys.c (scm_dirname, scm_basename): Move these to their own
535 page, at the end of the file.
536 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
538 * eval.h (scm_eval_options_interface): Add external prototype for this.
539 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
541 * eval.c (scm_lookupcar1): Make this static.
543 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
544 Make these prototype declarations, not K&R-style.
546 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
547 unsigned comparison warning.
549 * appinit.c: File removed. It had a single function in it, empty,
550 whose reason for existence is explained in no documentation or
551 comment. I think it's there as a default for some Tcl-style
552 initialization, but Tcl abandoned that approach a while ago.
553 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
554 (BUILT_SOURCES): Remove appinit.x.
555 * Makefile.in: Regenerated.
557 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
559 * Makefile.in: Regenerated using the last public version of
560 automake, not the hacked Cygnus version.
562 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
564 Remove Totoro kludge.
565 * Makefile.in, scmconfig.h.in: Regenerated.
566 * init.c, readline.c: Don't check if TOTORO is #defined.
568 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
570 * Makefile.am: Adjust for new thread configuration system.
571 (INCLUDES): Include the value of THREAD_CPPFLAGS.
572 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
574 (THREAD_LIBS): Definition deleted; automake will generate such
575 things automatically.
576 * Makefile.in: Regenerated.
578 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
580 Simplify smob and port marking; set the mark bit in the generic
581 marking code, and make marker routines only responsible for
582 turning up outgoing pointers.
583 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
584 before calling the marking function. Don't call the marking
585 function if it's zero.
586 * markers.c (scm_mark0): Just return #f. This function isn't
587 necessary at all now, but it's harmless to call it. We'll leave
588 it in so other folks' code doesn't croak at link time.
589 (scm_markcdr): Don't call SCM_SETGC8MARK.
590 * async.c (mark_async): Don't call SCM_SETGC8MARK.
591 * dynl.c (mark_dynl_obj): Same.
592 * root.c (mark_root): Same.
593 * srcprop.c (marksrcprops): Same.
594 * unif.c (markra): Same.
595 * variable.c (scm_markvar): Same.
596 * ports.c (scm_markstream): Same.
597 (void_port_ptob): Specify zero for our marking function.
598 * debug.c (debugobjsmob): Same.
599 * dynwind.c (guardsmob): Same.
600 * filesys.c (dir_smob): Same.
601 * fluids.c (fluid_smob): Same.
602 * fports.c (scm_fptob, scm_pipob): Same.
603 * mallocs.c (mallocsmob): Same.
604 * regex-posix.c (regex_t_smob): Same.
605 * smob.c (freecell, flob, bigob): Same.
606 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
607 * throw.c (jbsmob, lazy_catch_funs): Same.
609 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
611 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
612 scm_copy_tree on code in order not to let memoized code to leak
613 out. Thus, scm_copy_tree needs to copy vectors as well since
614 quasiquote can introduce evaluated code also inside vector
617 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
619 * eval.c (scm_copy_tree): Removed ability to copy vectors.
621 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
622 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
625 * unif.c: Say that ivect and uvect are of type signed and unsigned
626 long instead of int in commentary so that it correctly describes
629 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
631 * stime.c: Removed declaration of strptime. (It should be
632 declared by the system headers. If it turns out that some systems
633 don't, we'll handle that then.) (Thanks to Greg Troxel.)
635 * stime.h: Renamed TIMEH --> STIMEH
637 * backtrace.c (scm_display_error, scm_display_backtrace): In order
638 to increase portability, don't use structure assignment.
639 (Thanks to Nicolas Neuss.)
641 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
643 (finalize_fd_sets): Added empty statement after last case label.
644 (Thanks to Nicolas Neuss.)
646 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
649 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
651 * init.c, readline.c: OK, I won't have these readline.x bug
652 reports anymore. We've had them since April. The current reason
653 is a completely unintelligible failure of totoro.red-bean.com to
654 do the test for rl_getc_function in libreadline correctly. This
655 kludge overrides the test if we're on totoro so that the snapshot
656 generation process can work.
658 * readline.c: Define a strdup replacement if not existent on system.
660 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
662 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
663 This change makes scm_make_vector R5RS compatible. We cannot keep
664 the third argument since people want to be able to deduce the form
665 of the C function call only by looking at R5RS. (At the same time
666 we have removed some unnecessary complexity!)
668 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
669 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
670 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
671 argument in call to scm_make_vector.
673 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
675 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
676 This macro is useful in applications.
678 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
680 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
681 (scm_parse_path, scm_search_path): New Scheme level procedures.
683 * load.h (scm_internal_parse_path, scm_parse_path,
684 scm_search_path): Declared.
686 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
688 * filesys.c (dirname, basename): New procedures.
690 * init.c (scm_boot_guile_1): Removed condition around
693 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
694 new data type (guards) for representation of C level guards and
695 data on the wind chain.
696 (scm_internal_dynamic_wind): New function.
698 * dynwind.h: Declare scm_internal_dynamic_wind.
700 * root.h (scm_root_state): Added scm_cur_loadp.
702 * root.c (mark_root): Added comment about cur_loadp.
704 * load.c: #include "dynwind.h";
705 (scm_primitive_load): Use scm_inner_dynamic_wind to update
708 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
710 * ports.c (current-load-port): New procedure.
712 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
714 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
715 not a tty, return #f.
717 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
718 to Julian Satchell and Roland Kaufmann.)
720 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
721 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
723 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
725 * debug.h, debug.c (scm_start_stack): New function. Implements
726 the guts of old scm_m_start_stack.
728 * debug.c (scm_m_start_stack): Use scm_start_stack.
730 * init.c (scm_start_stack, scm_restart_stack): Renamed to
731 start_stack and restart_stack. (These have static scope.)
733 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
735 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
736 readline functions to come in release 2.3. (Thanks to Chet
738 (handle_errors): Use the above functions.
740 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
742 * readline.c: Improvements for readline support: Handle errors
743 better; Implement before-read-hook.
745 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
747 * init.c (scm_boot_guile_1), readline.c: Test for
748 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
749 assure that we have version >= 2.1.)
751 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
753 * readline.c (scm_readline): Defer interrupts while we're calling
756 * readline.c (scm_add_history): Bugfix: Do strdup before giving
757 away the string to add_history.
758 (completion_function): Do completion for readline. (Thanks to
760 (scm_filename_completion_function): New procedure: Filename
762 (current_input_getc): New function. Use this one instead of
763 standard getc from readline.
765 * throw.c, throw.h (scm_handle_by_throw): New function: This
766 handler throws errors to next handler on the dynwind chain.
768 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
770 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
773 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
775 * procprop.c (scm_i_procedure_arity): New function. Returns arity
777 (scm_procedure_properties): Modified to return arity together with
779 (scm_procedure_property): Added the read-only property `arity'.
780 (scm_set_procedure_property_x): It is an error to set the `arity'
783 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
784 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
786 * procprop.h (scm_sym_arity): New symbol.
788 * objects.c (scm_set_object_procedure_x): New procedure: Use this
789 to set the dispatch procedure of an operator or entity object.
791 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
792 Made procedure slots read-only.
794 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
795 scm_tcs_cons_gloc case in zero args switch; Fixed args
796 construction for operators in scm_tcs_cons_gloc case in two args
799 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
801 * fluids.c: Removed use of assert.h (in order to avoid
804 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
806 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
808 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
809 change makes the evaluator safer at the cost of evaluation speed.
810 It handles the case when the user has added a non-immediate
811 improper end of the application form, e.g., `(+ 0 . x)'.
812 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
813 minimize the extra cost as much as possible. The new code is
814 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
815 problem with structs planted directly in the code (e.g. by a
816 macro). This no longer causes segmentation fault. (Thanks to
819 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
820 arg `proc' in order to be able to throw errors; New argument
823 * Removed extra #include "debug.h"
825 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
827 * scmsigs.c: Declare usleep as returning void on some systems.
828 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
831 * coop.c (usleep): Return void on some systems.
833 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
835 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
837 * coop.c: Changed return type of usleep to int.
839 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
840 isn't found in the OS.
842 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
843 isn't enabled. (Thought that I had made this change ages ago...)
845 * iselect.c: Declare bzero if not defined by OS.
847 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
849 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
850 condition. (Thanks to John Tobey.)
852 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
853 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
856 * __scm.h: Start the long-term project of moving to POSIX threads.
857 Phase 1: Classification of all critical sections.
858 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
859 for A sections. (See comments in __scm.h for details.)
861 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
862 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
864 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
866 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
867 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
868 (libpath.h, versiondat.h): Replaced dependency on Makefile with
869 dependencies on $(srcdir)/Makefile.in
870 $(top_builddir)/config.status in order to avoid circularity.
872 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
873 from argc if argc was 0 initially.
875 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
876 in generation of libpath.h.
878 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
880 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
881 libguile from 2 to 3.
883 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
885 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
887 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
889 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
890 scm_set_port_column_x, scm_port_filename,
891 scm_set_port_filename_x): Removed optional arguments. Added
892 proper argument checking.
894 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
895 stack size in machine words.
897 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
898 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
899 to Ole Myren Röhne.)
901 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
903 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
904 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
906 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
909 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
910 procedure apply: Copy argument lists before pushing them unto the
911 environment so that the environment won't get mutated due to
912 manipulation of procedure arguments. This should perhaps be
913 regarded as a temporary solution until someone finds a more
914 efficient one. (Thanks to Maciej Stachowiak.)
916 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
918 * script.c (scm_compile_shell_switches): Use "guile" as default
919 zero arg if argc is NULL.
921 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
923 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
924 is zero. (Thanks to Dirk Herrmann.)
926 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
928 * ports.c (scm_add_to_port_table): First line is now line 0
929 (was 1). (Interface changed according to suggestion by Per
932 * backtrace.c (display_header): Add 1 to line and column numbers
933 when presenting them to the user.
935 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
936 from debug.c --> eval.c
938 * eval.h, eval.c (scm_eval_options_interface): New options
940 (SCM_EVAL_STACK): New option: Size of newly created stacks,
941 i.e. stacks for new threads.
943 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
945 * eval.c (unsafe_setjmp): Removed with #if 0.
947 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
950 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
951 to avoid compiler warnings.
953 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
955 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
957 * throw.c (handler_message): Print message on current error port
958 instead of default error port. (Thanks to Maciej Stachowiak.)
960 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
962 * ports.c (scm_add_to_port_table): allocate in units of
963 struct scm_port_table *, not struct scm_port_table.
964 * posix.c (scm_close_pipe): remove the port from the port table
966 Thanks to Rob Engle for both fixes.
968 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
970 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
971 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
973 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
975 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
977 * backtrace.c (display_error_body, display_backtrace_body),
978 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
979 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
980 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
981 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
984 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
985 don't receive the jmpbuf arg anylonger.
986 (scm_catch): Don't accept a #f tag.
987 (scm_throw): Check that key is a symbol.
988 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
990 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
992 * async.c (async_pending): Removed declaration.
994 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
996 * dynwind.c (scm_wind_chain): New debug function.
998 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
999 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
1000 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
1001 extra layer of functions around the body and handler of a thread.
1002 This extra layer makes sure that the handler is called in the
1003 dynamic context of the surround (= empty dynwind list), but under
1004 the *dynamic root* of the body. We can not use the dynamic root
1005 of the surround since that root belongs to another thread => stack
1006 is not handled correctly. It may seem ugly to use this extra
1007 layer, but the extra cost in terms of execution time is really
1008 negligible compared to the total amount of time required to create
1009 a thread, and it would reduce maintainability to duplicate the
1010 crucial and complicated steps performed by cwdr.
1012 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
1013 (SCM_ALLOW_INTS): Added thread switching code before interrupts
1014 get re-enabled. The important effect of this is that interrupts
1015 are blocked during thread switching so that thread data structures
1016 don't risk getting messed up by an unfortunate signal.
1017 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
1018 seems to do more aggressive optimization which actually move
1019 instructions around in these macros in a fatal way. Therefore:
1020 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
1021 just superstitious...)
1022 (SCM_TICK): Maybe do a context switch and take care of asyncs.
1023 This macro should be used instead of SCM_ASYNC_TICK since the
1024 latter doesn't do context switches any more.
1026 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
1027 instead of SCM_ASYNC_TICK.
1029 * coop.c, iselect.c: Since thread switches are now performed with
1030 interrupts masked, we can't use the old mechanism of delivering
1031 signals immediately when they arrive. Signals must instead be
1032 delivered when the asyncs run *after* the end of the critical
1033 section in scm_internal_select. But this also means after context
1034 switch so that the signal will be delivered to a different thread.
1035 To avoid this, I have changed the protocol of
1036 coop_wait_for_runnable_thread and friends so that they are allowed
1037 to return the original thread. So, if a signal arrives during
1038 scm_internal_select, we won't any longer be forced do a context
1039 switch, but can remain in the same thread and deliver the signal
1042 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
1043 scm_asyncs_pending and made it global.
1045 * iselect.c: Small fixes.
1047 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
1048 coop_condition_variable_init, coop_condition_variable_wait,
1049 coop_condition_variable_signal): Changed return type from `void'
1050 to `int'. This is to adhere closer to the pthreads interface.
1051 This, in turn, is part of an attempt to provide C versions of the
1052 mutex and condition variable primitives which can be part of a
1053 frontend to COOP or pthreads.
1055 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
1056 coop_condition_variable_destroy): New functions.
1058 * coop-threads.c (scm_wait_condition_variable): Use
1059 coop_condition_variable_wait_mutex.
1061 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
1062 Definitions moved to coop-defs.h.
1064 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
1065 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
1066 scm_cond_destroy): New C interface to mutecis and cond vars.
1068 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1070 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
1072 * iselect.c: Now several threads can wait on the same file
1073 descriptor. The behaviour is compatible with OS select: All
1074 threads waiting for the fd return with the same status.
1076 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1078 * coop-threads.c, threads.h (scm_spawn_thread): New function.
1079 Can spawn a thread from application C code.
1081 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1083 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
1084 gh_doubles2scm): New functions.
1086 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
1088 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
1089 commented-out version of gh_eval_str()
1091 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
1093 * socket.c (scm_bind): free soka after use.
1095 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
1097 * stime.c (tzvar): new variable.
1098 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
1099 avoid memory leaks when allocating.
1101 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
1103 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
1106 * gc.c, tags.h: Doc fixes.
1108 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1110 * eval.c (macro-eval!): Removed. This function was a design bug.
1111 It allowed memoized code to leak out to the scheme level. Most
1112 things that you could do with `macro-eval!' can be done with
1115 1997-12-20 Tim Pierce <twp@skepsis.com>
1117 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
1118 scm_fgets now depends on ftell(3) to know how many bytes were
1121 1997-12-15 Tim Pierce <twp@skepsis.com>
1123 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
1124 dealing with strings.
1126 1997-12-13 Tim Pierce <twp@skepsis.com>
1128 Make %read-line more suitable for implementing read-line efficiently.
1129 * ioext.c (scm_read_line): Strip the terminating newline from a
1130 string, and return a cons of the string and its terminator.
1132 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
1133 of the string that is read is stored in this memory location.
1134 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
1135 * genio.c, genio.h (scm_do_read_line): Update caller.
1136 * ports.h (scm_ptobfuns): Update typedef.
1137 * fports.c (scm_fptob, scm_pipob): Update struct.
1139 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1141 * filesys.c (set_element): Return file descriptor.
1142 (fill_select_type): Return the highest file descriptor.
1143 (scm_select): Tell select about the highest file descriptor. On
1144 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
1145 Therefore the extra overhead for calculating the maximum fd seems
1146 to be more than compensated. Is this correct? In any case,
1147 scm_internal_select will be much faster with this info.
1148 (scm_select, fill_select_type, set_element): Don't accept any kind
1149 of object in the file descriptor list or vector.
1151 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1153 * iselect.c (finalize_fd_sets): Bugfix.
1155 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1157 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1158 when using scm_internal_select (since we might switch to another
1161 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1163 * simpos.c (scm_system): always define: use sysmissing if not
1164 available. Check for HAVE_SYSTEM instead of _Windows (does
1165 Windows lack system or does it have an unusable one?).
1166 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1167 Let the argument be optional: if not supplied, call system(NULL).
1169 * ports.c (scm_close_port): relax the type check from OPPORTP to
1170 PORTP; closing a closed port is allowed.
1172 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1174 * fports.c (scm_fgets): Return if the last char in a chunk is
1175 newline. When fgets returns a string whose length is `size-1', it
1176 is ambiguous whether a whole line was retrieved, so we must check
1177 explicitly whether a line terminator is present.
1179 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1181 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
1182 before taking the CDR. (Thanks to Harald Meland.)
1184 * filesys.c (scm_stat): Slightly optimized.
1186 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
1188 * ports.c (scm_close_port): Make sure the port is open before
1191 * guile-snarf.in: Pass args through to gcc in a way that preserves
1192 whitespace boundaries. (Thanks to Greg Badros.)
1194 1997-12-02 Tim Pierce <twp@skepsis.com>
1196 * stacks.c (scm_frame_procedure): Reverse the logic in the return
1197 statement. (Thanks to Doug Evans for pointing this out.)
1199 1997-12-01 Tim Pierce <twp@skepsis.com>
1201 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
1203 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
1205 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
1206 errno macro expansion of this field name. (errno is a C
1207 preprocessor macro on some systems.)
1209 1997-11-29 Tim Pierce <twp@skepsis.com>
1211 * iselect.c: Doc fix.
1213 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
1215 * init.c (scm_start_stack): Removed initialization of
1216 scm_the_last_stack_var.
1218 * backtrace.h: Declare scm_the_last_stack_var.
1220 * backtrace.c: Define scm_the_last_stack_var.
1222 * root.c (mark_root): Don't mark the_last_stack_var.
1224 * root.h (scm_root_state): Removed the_last_stack_var.
1226 * throw.c: Added #include "fluids.h"
1227 (ss_handler): `the-last-stack' is now a fluid.
1229 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
1230 --> the_last_stack_fluid.
1232 * backtrace.c: Added #include "fluids.h"
1233 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
1234 (scm_backtrace): `the-last-stack' is now a fluid.
1236 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
1237 after scm_init_fluids.
1239 1997-11-28 Tim Pierce <twp@skepsis.com>
1241 * iselect.c: #ifdef USE_THREADS around thread-related includes.
1243 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
1244 DLSYM_ADDS_USCORE to decide whether to add an underscore.
1246 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1248 * iselect.c (coop_next_runnable_thread,
1249 coop_wait_for_runnable_thread): Disable interrupts so that no
1250 async is executed before a potential error_revive.
1251 (scm_internal_select): Disable interrupts during the parts of the
1252 code which manipulate the sleep queue and the file descriptors.
1254 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1256 * Makefile.am: Added iselect.c and iselect.h.
1258 * coop.c (coop_qinit): Initialize fields used by
1259 scm_internal_select.
1260 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1261 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1262 replacement in iselect.c.
1263 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1264 coop_join): If GUILE_ISELECT enabled, use
1265 coop_wait_for_runnable_thread instead of
1266 coop_next_runnable_thread.
1267 (usleep, sleep): New replacements for system functions if
1268 GUILE_ISELECT is enabled.
1270 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1272 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1274 * filesys.c: Added #include "iselect.h". Moved FD-macros to
1275 iselect.h. Implement Scheme level `select' using
1276 scm_internal_select. (See NEWS.)
1278 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1280 * init.c: Call scm_init_iselect.
1282 * iselect.h, iselect.c: New files. Implements
1283 scm_internal_select. (See NEWS.)
1285 1997-11-27 Tim Pierce <twp@skepsis.com>
1287 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1288 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1289 and scm_must_free, since ultimately the string returned will be copied
1290 by scm_makfrom0str anyway. Also, read any characters that may have
1291 been pushed onto the port with scm_ungetc.
1292 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1293 * ioext.c (scm_read_line): Free string after Guilifying it.
1294 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
1296 1997-11-26 Anthony Green <green@hoser.cygnus.com>
1298 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
1300 * gh.h: Safely wrap prototypes for c++ usage.
1302 1997-11-25 Mark Galassi <rosalia@cygnus.com>
1304 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
1305 gh_repl (argc, argv).
1307 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1309 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1310 and to invoke scm_shell().
1311 (gh_launch_pad): took out the loading of boot-9.scm from here,
1312 since it is probably best to let the user control that. In fact,
1313 gh_repl() now invokes scm_shell() which does that.
1315 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1317 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
1320 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
1322 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
1323 yesterday's underscore patch. (Thanks to Marius Vollmer for
1326 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
1328 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
1329 DLSYM_ADDS_USCORE is not defined.
1331 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
1333 * gh_data.c (gh_uniform_vector_length):
1334 (gh_uniform_vector_ref): started implementing the uniform types in
1337 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
1339 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1340 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1342 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1344 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1345 configure.in was changed).
1347 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
1349 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1350 * Makefile.in: Regenerated.
1352 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1354 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1355 OPORT is an `open' port, not an output port.
1357 * filesys.c (scm_close, set_element, get_element, scm_chown,
1358 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
1359 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
1360 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
1361 scm_close_port, scm_port_line, scm_set_port_line_x,
1362 scm_port_column, scm_set_port_column_x, scm_port_filename,
1363 scm_set_port_filename_x, scm_port_mode,
1364 scm_close_all_ports_except, scm_set_current_output_port,
1365 scm_set_current_error_port): Likewise
1366 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1367 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
1369 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
1370 * backtrace.c (display_backtrace_body): Likewise
1371 * fports (scm_setvbuf): Likewise
1372 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
1373 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
1374 scm_getpeername, scm_send, scm_sendto): Likewise
1375 * unif.c (scm_uniform_array_write): Likewise
1377 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
1379 Minor problems with substring-related tag changes.
1380 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1381 exactly what we want to leave in to detect substrings.
1382 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1383 * tags.h: Fix diagrams and comments describing the S tag bit;
1384 remove vestigial remarks about the D tag bit.
1385 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
1386 * strings.c: Formatting tweaks.
1388 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1389 variable first; then SCHEME_LOAD_PATH, with a warning message.
1390 (scm_parse_path): New function.
1391 * script.c: Doc fixes.
1393 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1395 Readline support, from Daniel Risacher.
1396 * readline.c, readline.h: New files.
1397 * init.c: #include "readline.h".
1398 (scm_boot_guile_1): Call scm_init_readline, if we have it.
1399 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1400 * Makefile.in: Regenerated.
1401 * scmconfig.h.in: Regenerated, after change to ../configure.
1403 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1405 * gh.h: gh_vector_set -> gh_vector_set_x
1407 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1409 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1410 with the ! -> _x mapping when going from Scheme to C.
1412 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1414 * gh.h (gh_reverse):
1422 (gh_assoc): added these gh_ functions implemented as macros.
1424 * gh_predicates.c (gh_null_p):
1425 (gh_string_equal_p): added these two missing predicates.
1427 * gh_list.c (gh_append):
1432 (gh_set_cdr_x): added these routines as I go through and try to
1433 complete the picture R4RS functions that should be mirrored in the
1436 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1438 * tags.h (scm_tc7_substring): Changed the comment and code to
1439 conform with the changes below. Folks! We have suddenly two new
1440 free tc7 codes!!! Jummy, jummy!
1442 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
1444 * Makefile.in: Rebuilt.
1445 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
1447 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
1448 * unif.c (scm_vector_set_length_x): Don't handle multibyte
1450 * tag.c (scm_utag_mb_string, scm_utag_mb_substring): Removed.

1462 * eq.c (scm_equal_p): Use SCM_TYP7S, not SCM_TYP7SD.
1463 * tags.h (SCM_TYP7SD): Removed.
1464 (SCM_TYP7D): Removed.
1465 (scm_tc7_mb_string): Removed.
1466 (scm_tc7_mb_substring): Removed.

1469 Don't include "mbstrings.h".
1470 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
1471 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
1473 Don't include "mbstrings.h".
1474 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
1475 (SCM_SYMBOL_SLOTS): Define as 4.
1476 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.

1497 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
1498 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
1500 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1502 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1504 * gh_test_c.c (c_vector_test): some improvements on the vector
1507 * gh.h (gh_vector): this used to exist but do the wrong thing.
1508 Now it (almost) does the right thing, though it takes a list
1509 instead of the individual arguments. I need to see how it could
1511 (gh_list_to_vector): added this function as a macro. Corresponds
1512 to Scheme's (list->vector ...).
1513 (gh_vector_to_list): added this function as a macro. Corresponds
1514 to Scheme's (vector->list ...).
1516 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1517 gh_vector_ref, so that it resembles the Scheme routines more.
1518 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1519 resembles the Scheme routines more.
1520 (gh_make_vector): this used to be (stupidly) called gh_vector().
1521 This is the right name, since it does the same thing as the Scheme
1522 (make-vector ...) procedure.
1524 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1526 * ports.h: #include "libguile/print.h"
1528 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
1529 Some indentation fixes.
1531 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
1532 longer a user field; New field: class_flags.
1534 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
1536 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
1538 * gh_data.c (gh_bool2scm): new function which replaces
1539 gh_int2scmb(), which is now tagged as obsolete.
1541 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1543 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1544 macros should by convention not test for NIMPness.)
1545 (SCM_COERCE_OPORT): Adjust indentation.
1547 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1548 SCM_NIMP test before SCM_PRINT_STATE_P.
1550 * struct.c, struct.h, gc.c: Renamed:
1551 scm_struct_i_layout --> scm_vtable_index_layout
1552 scm_struct_i_vcell --> scm_vtable_index_vcell
1553 scm_struct_i_vtable --> scm_vtable_index_vtable
1554 scm_struct_i_printer --> scm_vtable_index_printer
1555 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1557 * struct.c (scm_print_struct): Use new printer slot; Default
1558 printing: Also output hex code of vtable so that type identity
1559 will be indicated as well.
1560 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1561 Removed struct_printer_var; Removed struct-vtable-offset;
1562 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1563 vtable-offset-user): New constants.
1565 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
1566 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
1567 If this slot contains a procedure, use that to print structures of
1568 the type represented by this vtable.
1570 * print.c (scm_iprin1): Don't print arguments of macro
1571 transformers. (They are always: exp env.); Bugfix: Unmemoize
1572 transformer source with correct environment.
1574 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1576 Streamlining of call-with-dynamic-root:
1578 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
1579 there is now only one catch.
1580 (cwdr_outer_body): Removed.
1581 (cwdr_handler): New function.
1582 (scm_internal_cwdr): New function to perform the function of cwdr
1583 but take args that are more useful to C code. Also, the handler
1584 is now invoked *outside* of the new dynamic root, like the docs
1585 say. We no longer have to catch absolutely all errors, the caller
1586 is responsible for using a handler that does not throw, if he
1588 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1589 * root.h (scm_internal_cwdr): New prototype.
1591 Even more but risky streamlining:
1593 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1594 allocation of the jumpbuf of a root continuation. The changes
1595 below are controlled by it. They are now deactivated.
1596 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1597 the JMPBUF of the scm_rootcont to NULL before returning.
1599 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1600 when they are non-NULL.
1601 (scm_gc_mark): Likewise, mark only when non-NULL.
1603 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1604 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1606 * gc.c (scm_done_malloc): New function.
1607 gc.h (scm_done_malloc): New prototype.
1609 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
1610 (struct scm_print_state) [revealed]: New field.
1611 (scm_print_state_vtable): Make visible to the outside world for
1612 type checking purposes.
1613 (scm_valid_oport_value_p): New prototype.
1615 * print.c (scm_valid_oport_value_p): New function to check whether
1616 a certain value is acceptable as a port argument.
1617 (scm_print_state_vtable): New variable.
1618 (scm_free_print_state): Set `revealed' field to false.
1619 (scm_iprin1): Call user supplied closure printer with
1620 scm_printer_apply. Print in the traditional way when there isn't
1621 one or when it returns #f.
1622 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1623 Accept a port/print-state pair in addition to just a port.
1624 (scm_prin1): Don't return the print_state to the pool when it has
1626 (scm_printer_apply): Set `revealed' field of print_state to true.
1627 (scm_init_print): Set scm_print_state_vtable.
1628 (print_state_fluid, print_state_fluid_num): Removed.
1630 * throw.h (scm_handle_by_proc_catching_all): New prototype
1631 throw.c (scm_handle_by_proc_catching_all): New function
1633 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1635 * Makefile.in: Regenerated with automake 1.2c.
1637 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1639 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1640 was looping endlessly.
1642 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1644 * strports.c (scm_eval_string): Don't close the port.
1646 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1647 former returns a nice normal integer. (Thanks to Daniel
1650 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1652 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1653 makefile variable as a build parameter called LIBS. The
1654 build-guile program will use this, for the time being.
1655 * Makefile.in: Regenerated.
1657 Thanks to Shiro Kawai:
1658 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1659 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1662 * Makefile.in: Regenerated with automake 1.2a.
1664 * script.c (scm_compile_shell_switches): If we hit the -c or --
1665 arguments, don't set the car of (command-line) to scm_usage_name,
1666 the prettified name of the guile executable; give it the full
1667 path, the way shells usually handle $0.
1669 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1671 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1672 Scheme-level name `array-map' and renamed `serial-array-map' to
1673 `serial-array-map!'.
1675 * backtrace.c: Introduced exception handlers which now enclose
1676 `display-error' and `display-backtrace' so that error reporting
1677 won't get into infinite loops if an error occurs during displaying
1678 of the error. This can very easily happen with user supplied
1679 print call-back routines.
1681 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1683 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1684 the names `serial-array-map' and `array-map' should be removed.)
1686 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1688 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1689 Added #include "objects.h"
1691 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1692 Add #include "feature.h".
1694 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1695 (modinclude_HEADERS): Added objects.h.
1697 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1698 This test is needed at many places in the code and should be
1699 abstracted. (Motivated by the need of this test in libguiletk.)
1701 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1702 (scm_eval_string), load.c (scm_primitive_load,
1703 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1704 Use SCM_EOF_OBJECT_P.
1706 * eval.c (scm_init_eval): Add feature `delay'.
1708 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1710 * scmhob.h: Removed.
1712 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1714 * list.h (SCM_LISTn): New macros. Make list creation in C code
1715 prettier. The idea comes from STk.
1717 * sequences.h, sequences.c, append.h, append.c: Removed. These
1718 files implemented non-R4RS operations which would encourage
1719 non-portable programming style and less easy-to-read code.
1721 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1724 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1725 sequences.h, #include append.h.
1727 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1730 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1732 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1734 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1736 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1738 * eval.c: Added #include "objects.h"
1740 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1743 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1744 adjacent smob numbers.
1746 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1748 * procprop.h: Added declaration of scm_i_inner_name.
1750 * gsubr.c: New global symbol scm_i_inner_name.
1752 * debug.c (scm_procedure_name): Try procedure property
1753 `inner-name' if `name' fails.
1755 * print.c (scm_iprin1): Use scm_macro_name.
1757 * eval.c (scm_m_define): Give names to macros as well; Only the
1758 first top-level definition gives a procedure/macro a name.
1759 Otherwise confusing names can turn up in backtraces.
1760 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1761 `name'; Give names to macros as well.
1763 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1764 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1767 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1769 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
1771 (prinmacro): Removed. The code has been moved/merged into print.c
1772 in order to decrease code redundancy. We want macros to print in
1773 a way equivalent to procedures, and it would be silly to duplicate
1774 the required code. (We don't want to maintain two places.)
1775 (macrosmob): Print field is now a NULL pointer.
1777 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1778 scm_macro_transformer): New prototypes.
1779 (scm_tc16_macro): Declared.
1781 * * print.c (scm_iprin1): Added code for printing of macros. Macros
1782 are now printed in a way equivalent to procedures.
1784 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1786 * procs.h (scm_closure_p): Added declaration.
1788 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1790 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
1791 Shouldn't pass "heap" as the subr name.
1793 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1795 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
1796 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
1797 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1798 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1799 SCM_BOOL_T. Any non-false value is true.
1801 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1803 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1804 scm_gensym): Added prototypes.
1806 * symbols.c (scm_gensym): New function. This will speed up
1807 certain types of applications (such as macro systems) which
1808 generate lots of symbols.
1810 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1812 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
1814 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
1816 * unif.c (scm_shap2ra): tighten the checking of the array dimension
1817 specifier, since (2) or (2 . 3) would cause SEGV.
1818 (scm_transpose_array): more argument checking fixes.
1820 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1822 * Makefile.in: Regenerated.
1824 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1826 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
1828 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1830 * error.c, error.h (scm_error_callback): Removed (see NEWS).
1832 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
1834 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
1835 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
1838 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
1839 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1840 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
1841 scm_array_p, scm_array_rank, scm_array_dimensions,
1842 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
1843 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
1844 scm_array_prototype): Added case scm_tc7_wvect.
1846 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
1848 * errno.h: prototype for scm_strerror.
1849 * error.c (scm_strerror): new procedure.
1851 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1853 * list.c (scm_list_append_x): Allow non-pair as last argument.
1854 This is consistent with the R4RS append and is probably the
1855 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1857 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1859 * stime.h: prototype for scm_times.
1860 * stime.c (scm_times): new procedure.
1861 * ioext.c (scm_fseek): if the first argument is a file descriptor
1863 (scm_ftell): if the first argument is a file descriptor call lseek
1865 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
1866 * filesys.c (scm_chmod): if the first argument is a file descriptor,
1868 (scm_chown): if the first argument is a port or file descriptor,
1870 (scm_truncate_file): new procedure.
1871 Add DEFER/ALLOW INTS to a few other procedures.
1872 (scm_fsync): new procedure.
1873 (scm_open_fdes): new procedure.
1874 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
1876 (scm_fcntl): the first argument can now be a file descriptor. The
1877 third argument is now optional.
1879 * posix.c (scm_execl, scm_execlp): make the filename argument
1880 compulsory, since omitting it causes SEGV.
1881 (scm_sync): return unspecified instead of #f.
1882 (scm_execle): new procedure.
1883 (environ_list_to_c): new procedure.
1884 (scm_environ): use environ_list_to_c. disable interrupts.
1885 (scm_convert_exec_args): take pos and subr arguments and
1886 improve error checking.
1888 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1890 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1891 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1892 argument to SCM_ASSERT. Furthermore, the name of the function
1893 should be passed as first argument when signalling
1894 SCM_WNA. (Thanks to Thomas Morgan)
1896 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1897 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1898 dispatches on the number of actual args has a default case
1899 reporting an internal error. This is a vestige from a version
1900 that mallocated a SCM vector to hold the arguments. In the
1901 current version this check is too late: if it ever happens we will
1902 have already overstepped the bounds of the array.
1904 Also, the patch [...] adds a check for too many actual arguments."
1906 mdj: Removed check for "internal programming error".
1908 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1910 * gh_io.c (gh_write): New function.
1912 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
1913 throw.c (scm_internal_stack_catch): New sibling to the other catch
1914 functions. Code moved from gh_eval.c.
1915 throw.h: Added header.
1916 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
1917 scm_internal_stack_catch.
1919 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1921 * ioext.h: fix up prototypes.
1922 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
1923 Scheme name is now dup->fdes.
1924 (scm_dup_to_fdes): make the second argument optional and
1925 fold in the functionality of scm_primitive_dup.
1926 (scm_primitive_dup): deleted.
1928 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1930 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
1931 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
1932 ultrix are defined. Use setvbuf instead of setbuf.
1933 (scm_setvbuf): new procedure.
1934 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
1935 (scm_setfileno): moved from ioext.c.
1936 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
1937 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
1939 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1941 * fluids.c (scm_fluid_p): New function.
1942 * fluids.h (scm_fluid_p): New prototype.
1944 Sat Jul 26 21:33:37 1997 Marius Vollmer <mvo@zagadka.ping.de>
1946 * print.c (scm_iprin1): Enter printed structures into the print
1947 state as nested data while they are printed.
1948 (print_state_fluid, print_state_fluid_num): New variables.
1949 (scm_init_print): Initialize them.
1950 (scm_iprin): If print_state_fluid carries a print_state, use that
1951 instead of creating a new one.
1952 (scm_printer_apply, apply_stub, struct apply_data): New
1953 definitions to help with calling printer functions written in
1955 * print.h (scm_printer_apply): New prototype.
1957 * struct.c (scm_print_struct): Use scm_printer_apply to call the
1958 user defined struct printer.
1960 * dynwind.c (scm_dowinds): Handle fluids on the wind list.
1961 * fluids.h (scm_internal_with_fluids, scm_with_fluids,
1962 scm_swap_fluids, scm_swap_fluids_reverse): New prototypes.
1963 * fluids.c (scm_internal_with_fluids, scm_with_fluids,
1964 scm_swap_fluids, scm_swap_fluids_reverse): New functions.
1966 Fri Jul 25 12:05:46 1997 Marius Vollmer <mvo@zagadka.ping.de>
1968 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
1969 SCM_ASSERT: arg comes before pos.
1971 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1973 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
1974 to a list of length zero correctly.
1976 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1978 Supply an `fgets' method for port objects to do fast line i/o.
1979 * ioext.c (scm_read_line): New function.
1980 * genio.c (scm_gen_read_line): New function.
1981 * fports.c (scm_fgets): New function.
1982 (scm_fptob, scm_pipob): Add scm_fgets method.

1990 Mon Jul 21 04:03:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1992 * ioext.h: removed scm_duplicate_port prototype.
1994 * ioext.c (scm_primitive_dup2): return the new file descriptor
1995 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
1997 (scm_fdopen): bug fix: don't try to make port unbuffered until its
1998 stream has been set.
1999 (scm_duplicate_port): deleted, there's now an implementation in
2001 (scm_primitive_dup2): do nothing if newfd == oldfd.
2003 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
2005 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
2008 * ioext.h: new prototypes.
2009 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
2011 * fluids.c (next_fluid_num): don't do
2012 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
2014 * ports.h: prototypes too.
2015 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
2017 * fports.h: prototype too.
2018 * fports.c (scm_evict_ports): moved from ioext.c.
2020 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2022 * ports.c (scm_close_port): return a boolean instead of unspecified.
2023 throw an error if an error other than EBADF occurs.
2025 * filesys.h: scm_close prototype.
2026 * filesys.c (scm_close): new procedure, can close file descriptors
2027 and ports (scsh compatible).
2029 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
2032 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
2034 * fluids.c, fluid.h: New files.
2035 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
2036 (modinclude_HEADERS): Added "fluids.h"
2038 * init.c: Include "fluids.h". (scm_boot_guile_1): Added call to
2039 scm_init_fluids to initialize the fluid machine.
2040 (scm_start_stack): Initialize the fluids of the first root with
2041 scm_make_initial_fluids.
2043 * root.h: Added "fluids" member to scm_root_state.
2044 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
2045 (scm_make_root): Call scm_copy_fluids to make fluid bindings
2046 unique for the new root when it has a parent.
2048 * smob.h: Include "libguile/print.h" to make scm_print_state
2051 * dynl.c (free_dynl_obj): New function to free the dynamic object
2052 data. (dynl_smob): Use it.
2053 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
2054 the dynamic object data below the linking of the object to avoid
2055 memory leak when the linking code throws an error. Now the code
2056 leaks a whole dynamically linked library when must_malloc throws,
2057 but that should be much less likely.
2059 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
2061 Changes to compile under gnu-win32, from Marcus Daniels:
2062 * stime.c (tzset): If tzset isn't provided, make it a NOP.
2063 (scm_localtime): Change SCM_EOF to SCM_EOL.
2064 (scm_mktime): Likewise.
2065 * socket.c: Don't include sys/un.h unless autoconf tells
2066 us Unix domain sockets are available.
2067 (scm_fill_sockaddr): Ignore Unix domain code.
2068 (scm_addr_vector): Likewise.
2069 (scm_init_addr_buffer): Likewise.
2070 (scm_socketpair): Don't include unless socketpair was
2071 found during autoconf.
2072 * simpos.c (SYSTNAME): Treat cygwin like Unix.
2073 * scmsigs.c (scm_pause): Don't include unless pause was found
2075 * posix.c (scm_getgroups): Don't include unless support function
2076 was found during autoconf (in this case, getgroups).
2077 (scm_setpwent): For setpwent.
2078 (scm_setegid): For setegid.
2079 * net_db.c (scm_inet_netof): Don't include unless support
2080 function was found during autoconf (in this case, inet_netof).
2081 (scm_lnaof): For inet_lnaof.
2082 (scm_inet_makeaddr): For inet_makeaddr.
2083 (scm_getnet): For getnetent, getnetbyname, getnetbyaddr.

2094 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
2095 scm_misc_error, not SCM_EOF.
2097 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
2098 arguments for formatting the error message, not SCM_BOOL_F. I
2099 think this is left over from the (eq? '() #f) days.
2101 * read.c (recsexpr): Give this a dummy definition if
2102 DEBUG_EXTENSIONS isn't #defined.
2104 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
2106 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
2109 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>
2111 * root.c (cwdr_outer_body): Bugfix: Pass `c' instead of `&c' to
2114 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
2116 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
2117 alloca.lo will be included in @LIBLOBJS@. Something better than
2118 this should be possible.
2119 * Makefile.in: Regenerated.
2121 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2123 * simpos.h: prototype for scm_primitive_exit.
2124 * simpos.c (scm_primitive_exit): new procedure, terminates the
2125 process without unwinding the stack.
2127 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
2129 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
2130 argument and logior its components together, so the user doesn't
2131 have to do this explicitly. Also, if regexp/basic is supplied, then
2132 turn off REG_EXTENDED.
2133 (scm_init_regex_posix): New regexp/basic symbol.
2134 (REG_BASIC): #define this if it is not already present.
2136 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2138 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
2139 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
2140 (CLEANFILES): New target, clean versiondat.h, libpath.h.
2141 (DISTCLEANFILES): New target, clean *.x.
2142 * Makefile.in: Regenerated.
2144 Tue Jun 24 00:29:07 1997 Jim Blandy <jimb@floss.red-bean.com>

2147 years in usage message.
2149 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
2150 * Makefile.in: Regenerated.
2152 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
2153 flag; I don't think we support it.
2154 (scm_make_regexp): Make sure the user doesn't pass the
2157 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
2159 (scm_init_regex_posix): Define constants for the REG_mumble flags;
2160 name them according to the SCSH convention: regexp/mumble.
2162 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
2164 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
2166 * Makefile.am (libpath.h): Include the values of all the standard
2167 Makefile directory variables. Print a message, but don't print
2169 (versiondat.h): Print a message, but don't print all the commands.
2170 * load.c: #include "alist.h".
2171 (init_build_info): New function.
2172 (scm_init_load): Call it.
2173 * Makefile.in: Regenerated.
2175 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
2177 * root.c: Establish a reliable catch-all handler for the new root.
2178 After all the Scheme handler function might signal an error too,
2179 and we don't want to lose that.
2180 (cwdr_inner_body): Renamed from cwdr_body.
2181 (cwdr_outer_body): New function, to establish the user's handler,
2182 and pass control to cwdr_inner_body.
2183 (cwdr): Establish the reliable catch-all handler here, and pass
2184 control to cwdr_outer_body.
2185 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
2186 the user's handler through to cwdr_outer_body.
2187 * throw.c (scm_handle_by_message): Move guts into....
2188 (handler_message): New static function.
2189 (scm_handle_by_message_noexit): New function.
2190 * throw.h (scm_handle_by_message_noexit): New prototype.
2192 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
2193 across this. Only works on GCC. Otherwise, we hope for the best.
2194 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2195 the feeling that real thread systems will not need this...
2197 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2199 Try to detect when people are using one version of libguile and a
2200 different version of ice-9. People have been skewing things and
2201 sending in bug reports.
2202 * Makefile.am (versiondat.h): New file to generate.
2203 * version.c: #include "versiondat.h", to get version info.
2204 (scm_libguile_config_stamp): New function.
2205 * script.c: #include "version.h".
2206 (scm_compile_switches): Call scm_version to get version number.
2207 * scmconfig.h.in, Makefile.in: Regenerated.
2208 * Makefile.in: Regenerated.
2210 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
2211 primitive definitions under their Scheme names.
2213 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2214 1:2. Helps avoid confusion between installed and uninstalled libs.
2216 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2219 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2220 backslash from definition; this should be used like: GDB_INTERFACE;
2222 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2224 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
2225 new port unbuffered until its stream has been set.
2227 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2229 * ports.h: new prototype.
2230 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
2232 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
2234 Make things compile neatly under Sun's C compiler.
2235 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
2236 * extchrs.c (xmbtowc): Make the second arg a normal char, not
2237 unsigned, because that's what the ANSI function takes.
2238 * extchrs.h (xmbtowc): Corresponding change to prototype.
2239 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2241 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2242 argument plain char *.
2243 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2245 * tag.c (scm_tag): Remove unreachable statement.
2246 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2247 top of the word, it should be unsigned.
2249 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2250 is defined, to avoid warnings; it's only used in the
2251 conflict-checking code. Which might go away anyway.
2252 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2253 conditionals; put the label definition in an #if too, to stifle
2256 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2257 ChangeLog-threads in the distribution.
2258 * Makefile.in: Regenerated.
2260 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2262 * guile-snarf.in: Changed regexp to support CPPs that insert
2263 whitespace between lexical tokens (which munges the `%%%' snarf
2266 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2268 * load.c (scm_init_load_path): Append $(datadir)/guile to
2269 %load-path, so modules do not have to be installed in Guile's
2270 current version directory.
2272 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2274 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2275 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2276 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2277 call the sysdep functions with deferred ints.
2278 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2279 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2280 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2283 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2286 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2288 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2290 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2292 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2295 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2297 * eval.c (scm_lookupcar1): New procedure to cope with a race
2298 condition during lookup (when using threads).
2299 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2300 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2303 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2305 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2306 supplied. (Change from Tim Pierce.)
2308 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2310 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2311 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2312 default and not `()'. `#f' is the canonical non-value in Scheme,
2315 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2317 * struct.c (struct_printer): New variable that holds a handle on
2318 the Scheme variable *struct-printer*. This variable can be set by
2319 Scheme code to override the printing of structures.
2320 (scm_print_struct): If struct_printer is set, call it. If it is
2321 not set, or returns #f, print the structure in the old fashion.
2322 Include "eval.h" for scm_apply.
2324 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2326 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2327 scm_struct_i_n_words to get the number of fields, not
2328 -scm_struct_n_extra_words.
2330 On the route to fancier struct printing:
2331 * struct.c (scm_print_struct): New function to print a structure.
2332 Include "genio.h" to support it. This function doesn't do
2333 anything interesting right now, but I think it should be here
2335 * struct.h: Include "print.h" and add prototype for
2337 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2338 print structures ourself.
2340 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2342 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2343 before applying the handler in case it doesn't return.
2345 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2347 * scmsigs.h, async.h: updated.
2349 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2352 * posix.c (scm_uname): interpret only negative values as an error.
2353 Solaris normally returns a positive value.
2355 * script.c (scm_compile_shell_switches): if we are not going into
2356 an interactive repl, set scm_mask_ints to zero so that asyncs can
2359 * simpos.c (scm_system): don't ignore/unignore signals around
2362 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2365 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2366 done in boot-9.scm instead.
2368 * scmsigs.c, async.c: Major rewriting of signal handling code.
2369 (scm_sigaction): new procedure.
2370 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2372 (scm_raise): return unspecified, throw error on failure.
2374 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2376 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2377 feature, to help boot-9.scm decide whether to import the regex
2380 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2382 * eval.c: Include scmconfig.h at the beginning of the file so that
2383 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2386 * regex-posix.c: #include "_scm.h" before conditionally #including
2387 <regex.h>; the former defines HAVE_REGCOMP.
2389 * regex-posix.c: #include <regex.h> conditionally, so the file is
2390 CPP'able (for dependency scanning) even on systems that don't have
2393 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2395 Add new R4RS-compliant syntax for keywords.
2396 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2397 regardless of the setting of the `keywords' read option.
2398 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2399 can be re-read no matter what the setting of the `keywords' read
2402 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2404 Add support for POSIX regular expressions.
2406 * regex-posix.c, regex-posix.h: New files. (Some code
2407 is taken liberally from rx/rgx.c in the old Guile dist.)
2409 * init.c: Include regex-posix.h.
2410 (scm_boot_guile_1): Call scm_init_regex_posix.
2412 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2413 Add regex-posix.[ch] sources.
2414 * Makefile.in: Regenerated.
2416 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2417 to do this automatically? It didn't for me, bleh.)
2419 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2421 * fports.c (print_pipe_port): New function.
2422 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2423 latter doesn't even take the right arguments.
2425 * Makefile.am: Increment shared lib revision number. I think
2426 sometimes the uninstalled Guile finds the installed shared lib;
2427 Gord says doing this might help. As things turned out, I can't
2428 say whether it does.
2429 * Makefile.in: Regenerated.
2431 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2432 passing it as the closure argument to scm_boot_guile. (Bill
2435 * ports.c (print_void_port, putc_void_port, puts_void_port,
2436 write_void_port, flush_void_port, getc_void_port, close_void_port,
2437 noop0): Use ANSI prototypes instead of K&R declarations, so the
2438 initialization of void_port_ptob gets aggressively type-checked.
2439 Fix arguments of print_void_port and write_void_port. (Bill

2473 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2475 * script.c (scm_find_executable): Use prototype-style definition
2476 here; apparently it's not quite right to have const in a prototype
2477 and then use a K&R declaration. I wonder if stuff like this will
2478 go away if we compile with -Wrequire-prototypes, or whatever that
2479 is... (Bernard URBAN)
2481 * scmhob.h: New text from Bernard URBAN.
2483 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2485 * script.c: Don't #define const on hpux. Configure takes care of
2486 this. (Thanks to Larry Schwimmer.)
2488 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2489 decide whether to #include <unistd.h>, instead of listing a bunch
2490 of systems. Don't #include stdio twice. Removed dyked-out
2491 definition of scm_find_impl_file.
2493 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2495 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2496 library version info to 1:0.
2497 * Makefile.in: Regenerated.
2499 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,
2500 gdb_interface.h, gdbint.c, gdbint.h, gh_data.c, gh_init.c,
2501 gh_io.c, gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c,

2503 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2504 throw.c: Update copyright years; these files have been worked on
2505 significantly in 1997, but only had copyright years for 1996.
2506 Also, change name of copyright holder on some from Mikael
2507 Djurfeldt to Free Software Foundation; he has signed papers
2508 assigning the changes to the FSF.
2510 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2511 reason not to give the user the option.
2513 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2514 Return #f on end-of-file when scanning table (i.e. when called
2515 with no arguments). Try to catch errors, when we can.
2516 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2518 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2519 external declarations. These are useful.
2521 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2523 * posix.c: don't include <sys/select.h> or define macros for
2524 select, since they were not used in this file.
2526 * filesys.c (scm_select): make the fifth parameter microseconds,
2527 not milliseconds. let the fourth parameter be either a real value
2528 or an integer or #f. The first, second and third arguments can
2529 now be vectors: the type of the corresponding return set will be
2531 (set_element, get_element): new static procedures.
2533 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2535 * strports.c (scm_eval_string): New function.
2536 (scm_eval_0str): Trivially re-implemented in terms of
2538 * strports.h (scm_eval_string): New extern decl.
2540 * net_db.c (h_errno): Add extern decl for this.
2542 * fports.c (local_pclose): New function.
2543 (scm_pipob): Use it in the initializer here.
2546 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2547 Use a meaningful error message when signalling an error. For
2548 this, scm_gethost must check h_errno rather than errno.
2550 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2552 * Makefile.in: Regenerated, using automake-1.1p.
2554 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2556 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2557 not SCM_UNSPECIFIED.
2559 * script.c (scm_compile_shell_switches): don't append (quit) if
2561 (scm_shell): call scm_exit_status and exit on the result of the
2564 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2566 Ensure that shared substrings are handled properly when passed to
2567 a system call or other foreign function. Many thanks to Tim
2569 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2570 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2571 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2572 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
2573 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
2574 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
2575 (scm_display_error_message): use RO macros when strings may be RO.
2576 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
2577 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
2578 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
2579 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
2580 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
2581 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
2582 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
2583 scm_strftime), vports.c (scm_make_soft_port): use
2584 SCM_COERCE_SUBSTR to make sure shared substrings are
2587 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2589 * error.c (scm_error): Add newline to error message.
2591 * init.c (scm_init_standard_ports): Doc fix.
2593 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2595 * dynl-shl.c: Completely replaced with new code from Bernard
2598 * script.c (scm_ice_9_already_loaded): New variable.
2599 (scm_compile_shell_switches): Use it.
2601 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2603 * filesys.c (scm_input_waiting_p): add missing third argument to
2606 * stime.c (scm_localtime): copy the result of localtime before
2607 calling gmtime in case they share a buffer.
2608 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2611 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2613 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2615 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2617 * Makefile.am (check-local): New target, which causes 'make check'
2618 to run gh_test_c and gh_test_repl, with some trivial input.
2619 * Makefile.in: Rgnrtd.
2621 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2623 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2626 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2628 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2629 sure how this was supposed to work.
2630 (scm_async_click): don't send SCM_TICK_SIGNAL.
2631 (scm_init_async): don't initialize %tick-thunk.
2633 * the following change doesn't affect the Scheme interface:
2634 gc-thunk is called at the end of garbage collection. however it's
2635 no longer implemented by pretending it's a signal.
2637 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2638 system async corresponding to scm_gc_thunk.
2639 * async.h: declare scm_gc_async.
2640 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2641 gc-thunk directly, instead of going through a signal handler.
2642 (scm_gc_async): new variable, points to the GC system-async.
2643 (scm_init_async): save the GC async as scm_gc_async instead
2644 of using system_signal_asyncs.
2645 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2647 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2649 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2650 Don't screw up if we're interrupted.
2651 * Makefile.in: Regeneradet.
2653 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2655 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2657 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2658 we're not using AM_INIT_GUILE_MODULE any more.
2659 * Makefile.in: Reneregated.
2661 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2663 Functions for finding variable bindings, grace à Tim Pierce.
2664 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2665 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2667 Get 'make dist' to work again.
2668 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2669 * Makefile.in: Regenerated, like a surry without a fringe on top.
2671 Changes for reduced Guile distribution: one configure script,
2673 * configure.in, configure: Removed.
2674 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2675 real configure script lives.
2676 * Makefile.in, scmconfig.h.in: Regenerated.
2678 * init.c: #include "script.h", to get prototype for script.c's
2681 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2683 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2684 scm_must_malloc, not raw malloc.
2686 * script.c (scm_compile_shell_switches): Dyke out debugging output
2689 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2691 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2693 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2694 system has them. Hope this is safe. Previously
2695 sys/timeb.h was included if HAVE_FTIME was defined or if
2696 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2697 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2699 * ioext.c (scm_setfileno): add missing third argument to
2700 scm_misc_error call.
2702 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2704 * eq.c (scm_equal_p): Correctly compare strings of different
2705 varieties. (Thanks to Tim Pierce.)
2707 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2709 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2710 #! block comment must occur on a line all by itself.
2712 Move most of the guts of shell command processing into libguile,
2713 so guile.c can be very small (and eventuallly auto-generated. (I
2714 mean, generated mechanically, not self-generated. Hmm.))
2715 * guile.c, script.c, script.h: New source files.
2716 * init.c (scm_boot_guile_1): Call scm_init_script.
2717 * libguile.h: #include "script.h".
2718 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2719 targets, for new executable.
2720 (libguile_la_SOURCES): Mention script.c.
2721 (modinclude_HEADERS): Add script.h.
2722 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2723 not dynamic linking is enabled. This is because we're generating
2724 executables now. Move CY_AC_WITH_THREADS call after those, so the
2725 values of cy_cv_threads_libs captures the libs chosen above.
2726 * Makefile.in, configure, aclocal.m4: Regenerated.
2728 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2729 We don't maintain this interface any more, and it just confuses
2732 * alloca.c: #include <scmconfig.h>, not <config.h>.
2733 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2734 it'll get included in disties.
2736 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2738 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2739 be distributed, because they confuse people.
2740 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2742 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2744 * configure.in: check for presence of gethostent (not present on
2745 OpenBSD by default).
2746 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2747 * configure, scmconfig.h.in: Regenerated.
2749 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2751 * backtrace.c (scm_backtrace): Split message string across
2752 newlines properly. GCC is more tolerant of this than other
2755 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
2757 Merge threads directory into libguile.
2758 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
2759 threads.h: New source files.
2760 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
2761 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2763 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2764 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2765 coop-threads.c.cygnus, coop-threads.h.cygnus.
2766 * configure.in: If we're using threads, include threads.o in
2768 * _scm.h, libguile.h: threads.h lives in this directory now.
2769 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2770 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2771 currently used, but brought along for information's sake.
2772 * ChangeLog-threads: log from old 'threads' directory.
2773 * Makefile.in, configure: Rebuilt.
2775 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2777 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2780 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2782 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2784 Merge GH interface library into libguile.
2785 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
2786 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2787 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2788 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2790 (EXTRA_libguile_la_SOURCES): ... here.
2791 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2792 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2793 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2794 New variables, describing how to build the gh test programs.
2795 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2796 build the test programs, and we probably should have been linking
2797 libguile.la against them all along, to support AIX shared libs.
2798 Add cflags for threads to CFLAGS; add libs for threads to new
2799 variable THREAD_LIBS, used in Makefile.am.
2800 * ChangeLog-gh: log from old `gh' subdirectory.
2801 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2803 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2805 * acconfig.h: Undo change of Apr 9; including the definition of
2806 PACKAGE in the guile headers conflicts with applications' own
2808 * scmconfig.h.in: Regenerated.
2810 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
2812 * filesys.c (scm_fcntl): New function from Roland McGrath.

2814 * filesys.h: Added prototype.
2816 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
2817 when PROC is receiving no arguments.
2819 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2821 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2822 have S_IFSOCK. This is the case under Ultrix.
2824 * posix.c (scm_status_exit_val, scm_status_exit_val,
2825 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2826 Ultrix versions of WIFSTOPPED, etc., which assume that their
2827 arguments are lvalues (hmm).
2829 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2831 * eval.c: Doc fixes.
2833 * throw.c: Doc fixes; rearranged.
2835 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
2837 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
2839 * acconfig.h: Added entry for PACKAGE.
2840 * scmconfig.h.in: Regenerated.
2842 Changes to work with automake-1.1n, which has better libtool support.
2843 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2844 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
2846 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
2848 * Makefile.in: Rebuild.
2850 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2852 * stime.c (scm_mktime): take an optional zone argument.
2853 (scm_localtime): check putenv return value.
2854 (scm_strftime, scm_strptime): moved from posix.c. move #include
2856 stime.h, posix.h: update prototypes.
2857 (bdtime2c, setzone, restorezone): new static procedures.
2858 (scm_mktime, scm_strftime): use them.
2859 (scm_strftime): don't call mktime before strftime. Use
2860 filltime for return value.
2861 (filltime): convert NULL zname to #f.
2862 (scm_strptime): return a count of characters consumed, not
2863 the remaining string.
2865 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2867 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
2868 (scm_mktime): likewise.
2870 Uncomment localtime and mktime.
2872 * configure.in: add AC_STRUCT_TIMEZONE.
2874 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2876 * stime.c (scm_init_stime): don't define ticks/sec.
2877 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2878 return value problem and is still portable.)
2880 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2882 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2883 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2884 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2885 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2886 cpp_err_symbols.c): Corresponding changes.
2887 * Makefile.in: Regenerated.
2889 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2891 * posix.c (scm_putenv): don't check HAVE_PUTENV.
2892 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
2893 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
2894 * putenv.c: new file, from sh-utils 1.12.
2896 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2897 since allocation isn't for Scheme objects.
2898 (scm_putenv): copy strings before placing in the environment.
2900 * stime.c (scm_current_time): throw an error if time returns -1,
2901 instead of returning #f.
2902 (scm_get_internal_real_time, scm_get_internal_real_time): use
2903 scm_long2num for return value instead of SCM_MAKINUM.
2905 * stime.h: prototypes updated.
2907 * stime.c (scm_time_in_msec): apparently unused, deleted.
2909 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2911 * configure.in: check for gettimeofday.
2913 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2914 which may be more usefully portable than a gettimeofday interface.
2916 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2918 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
2920 * Makefile.in: Regenerated.
2922 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2924 * stime.c (filltime): recovered static procedure.
2925 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
2928 * posix.h: add prototype for scm_close_pipe, remove prototypes for
2929 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2931 * posix.c (scm_mknod): split the mode argument into type and perms
2932 arguments, like the extra fields returned by stat.
2934 * fports.c (scm_pipob): set the close, free and print procedures.
2935 (scm_close_pipe): new procedure.
2937 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2938 define them in boot-9.scm
2940 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2942 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
2943 wan't defined. Don't include fd.h.
2945 * Previously fd.h was regenerated whenever configure was run,
2946 forcing a couple of files to be recompiled.
2948 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
2949 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
2950 Check for _fileno as well as _file.
2952 * ioext.c: don't fd.h.
2953 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
2956 * Change the stratigy for getting information about errno
2957 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
2958 generating lists of symbols during the build process, which will
2959 not always work, include comprehensive lists in the distribution.
2960 To help keep the lists up to date, the "check_signals" and
2961 "check_errnos" make targets can be used.
2963 * configure.in: don't check for a command to extract errno codes.
2964 * Makefile.am: update file lists, remove errnos.list and errnos.c
2965 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
2966 check_errnos targets.
2967 (CLEANFILES): remove errnos.c and errnos.list, add
2968 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
2969 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
2970 * errnos.default: deleted.
2971 * cpp_signal.c: new file.
2972 * cpp_errno.c: renamed from errnos_get.c.
2973 * cpp_err_symbols, cpp_sig_symbols: new files.
2974 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
2975 * error.c (scm_init_error): #include cpp_err_symbols instead of
2977 * posix.c (scm_init_posix): don't intern signal symbols. #include
2980 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
2982 * strop.c (scm_i_index): allow the lower bound to be equal to the
2983 length of the string, so a null string doesn't always give an error.
2985 * posix.h: new prototypes.
2986 * posix.c (scm_status_exit_val, scm_status_term_sig,
2987 scm_status_stop_sig): new functions, as in scsh. They break down
2988 process status values as returned by waitpid.
2990 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
2992 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
2993 configure doesn't know about it.
2995 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2997 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
2999 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
3000 which defines C variables with global linkage.
3002 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3004 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
3007 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
3009 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
3010 has time to check why this doesn't work well with continuations.
3012 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
3014 * Fix shell syntax error; some shells won't tolerate
3015 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
3017 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3019 * posix.c (scm_uname): throw an error if uname fails instead
3022 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
3024 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
3027 * async.c (scm_ints_disabled): definition moved from error.c.
3029 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3031 * acconfig.h: Removed PACKAGE.
3033 * scmconfig.h.in: Regenerated.
3035 * snarf.h: g++ says it's non-portable not to specify the first
3036 argument in a varargs declaration. I introduced the first
3037 argument by using preprocessor conditionals.
3039 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
3041 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
3042 (scm_freopen): use RO string macros for filename and modes.
3043 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
3045 * posix.c (scm_getgrgid): simplify conversion of name to C string.
3046 (scm_mknod): use RO string macros for path.
3048 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
3049 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
3051 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
3052 use SCM_ROSTRINGP and SCM_ROCHARS.
3054 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3056 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
3059 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
3060 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
3061 support for byte vectors.
3063 * print.c (scm_iprin1): Limit number of vector elements printed
3064 according to pstate->length.
3066 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3068 * backtrace.c (scm_display_error_message): don't segv if message
3071 * error.h: prototype for scm_error_scm.
3073 * error.c (scm_error_scm): new procedure, reimplements scm-error
3074 in C and uses scm_error.
3076 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3078 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
3079 pointer to the Scheme variable read-hash-procedures and intern it
3080 in scm_init_read. Modify scm_read_hash_extend and
3081 scm_get_hash_procedure to use the pointer.
3083 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3085 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
3086 (SCM_KEYWORD_STYLE): defined.
3088 * read.c (scm_read_opts): add a keywords option. This isn't a
3089 boolean option, in case someone wants to add support for DSSSL
3091 Setup scm_keyword_prefix symbol.
3092 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
3094 I've left keyword support disabled by default, since it doesn't
3095 seem to break the module system and it gives R4RS standard behaviour.
3096 It can be reactivated with (read-set! keywords 'prefix).
3098 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3100 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
3101 before constructing arbiter.
3103 * eval.c (scm_m_define): Bugfix: Check that the object is a
3104 closure before setting the procedure property!
3106 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
3108 * ports.c: Removed `ungetc-char-ready?'.
3110 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
3112 * read.c (scm_init_read): intitialise scm_read_hash_procedures
3113 (idea from Mikael: make it a pair so scm_permanent object only
3115 (scm_read_hash_extend): don't call scm_permanent_object.
3116 (ideas from Mikael): if chr is already in the list, replace its
3117 procedure instead of appending it again. If proc is #f, remove
3119 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
3121 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
3123 * gdbint.c (gdb_read): update scm_lreadr usage.
3125 * load.h: update prototypes.
3127 * load.c (scm_primitive_load, scm_read_and_eval_x,
3128 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
3130 * read.h: add prototype for scm_read_hash_extend. Change args for
3133 * read.c (scm_read_hash_procedures): new variable.
3134 (scm_read_hash_extend): new procedure.
3135 (scm_get_hash_procedure): new procedure.
3136 (scm_lreadr): use scm_get_hash_procedure instead of an argument
3137 for extended # processing.
3138 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
3139 scm_read_token): remove case_i, sharp arguments. Change callers.
3141 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
3143 * read.h (SCM_N_READ_OPTIONS): increase to 3.
3144 (SCM_CASE_INSENSITIVE_P): define.
3146 * read.c: add case-insensitive option to scm_read_opts.
3147 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
3148 to determine whether to convert symbol case.
3149 (default_case_i): definition removed.
3150 * read.c (scm_read_token): if case_i, downcase ic before doing
3153 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3155 * configure.in: Added configuration option `guile-debug'.
3156 Configure with --enable-guile-debug if you want a bunch of extra
3157 functions used for debugging when developing Guile.
3159 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3161 * procs.c (make-cclo): New undocumented debugging procedure: Make
3162 compiled closure with internal procedure PROC and length LENGTH.
3163 Only compiled if GUILE_DEBUG is defined.
3165 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3167 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3169 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3171 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3172 with 3 or more args internally to the evaluator.
3174 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3176 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3177 with 3 or more args internally to the evaluator. This is mainly
3178 because we don't want to pass entry and exit points of the
3179 debug support twice, but it also seems to increase the speed of
3180 the evaluator for such calls (e. g. (+ 1 2 3)).
3182 * backtrace.c (scm_display_application): New procedure:
3183 display-application; Set fancy printing parameters individually
3184 for different types of display (backtrace, error, application).
3185 (These should of course be customizable!)
3187 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3188 clear the CHECK-flags.
3190 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3192 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3194 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3196 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3197 from pairs with a GLOC in the car.
3199 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3200 otherwise `symbol-hash' will behave badly.
3201 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3202 we get segmentation fault!
3204 * symbols.c: Added #include "weaks.h". New functions:
3205 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3206 moved to an extraneous library when we split libguile.)
3208 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3210 * filesys.c (scm_stat): stat now takes fport arguments too as
3211 documented in the manual.
3213 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3215 * debug.c (scm_single_step): Bugfix: Call continuation with
3216 scm_call_continuation instead of throwing to it.
3218 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3220 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3221 argument wasn't declared to be optional.
3223 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3225 * stime.c (scm_init_stime): Add feature "current-time".
3227 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3229 * throw.h: prototype for scm_exit_status.
3230 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3231 args to derive an exit status. Allows (quit) to work from a
3233 (scm_exit_status): new function.
3236 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3238 * eval.c (scm_deval): Removed some old code.
3239 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3241 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3244 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3247 * procs.c: Introduce the existent C function scm_thunk_p at the
3248 Scheme level as well.
3250 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3252 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3253 used from C to easily lookup the value of a symbol in the current
3256 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3258 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3259 scm_init_unif in this file. This will also fix a previous problem
3262 * configure.in: Added AM_MAINTAINER_MODE
3264 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3266 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3269 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3271 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3272 source files that are not always included in libguile but should
3273 have their dependencies calculated by automake. This variable is
3274 recognized by automake, no further magic is needed.
3275 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3276 to deal exclusively with *.lo files, as it seems. The *.o files
3277 are built automatically when the corresponding *.lo file gets
3280 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3282 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3285 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3287 * unif.c (scm_array_set_x): minor change to argument error checking.
3289 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3291 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3292 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3293 They should only be included in the library at configure.in's
3295 (libguile_la_LDADD): Include the appropriate .lo files here.
3296 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3297 so we know when to build them (and their .lo bretheren).
3298 * configure.in (LIBLOBJS): New substituted variable. We let
3299 configure decide which .o files to include in LIBOBJS, and then
3300 put the corresponding list of .lo files in LIBLOBJS. The latter
3301 is what we pass to libtool.
3302 * Makefile.in, configure: regenerated.
3304 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3306 * symbols.c (scm_sysintern0): New function. Contains the core of
3307 old scm_sysintern but doesn't take a second value argument.
3308 (scm_sysintern): Now uses scm_sysintern0.
3309 (scm_sysintern_no_module_lookup): Renamed to
3310 scm_sysintern0_no_module_lookup and doesn't take a second value
3311 argument any longer.
3313 * symbols.h (scm_sysintern0: Added declaration.
3315 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3316 scm_sysintern when interning option keys. Otherwise we risk
3317 destroying the values of already interned variables.
3319 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3320 scheme-level boolean (use SCM_NFALSEP).
3322 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3324 (scm_backtrace): New function. (C version of old function from
3325 boot-9.scm) Motivation: Make it possible to display backtraces
3326 without depending on boot-9.scm. (I'm uncertain if this
3327 motivation is good enough...)
3329 * root.h (scm_root_state): Add member the_last_stack_var.
3330 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3332 * root.c (mark_root): Mark scm_the_last_stack_var.
3334 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3337 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3339 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3340 1. mark_lazy_catch didn't mark the smob.
3341 2. Both functions above have standard variants:
3342 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3343 free_lazy_catch --> scm_free0.
3345 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3347 * throw.c (scm_internal_lazy_catch): New function.
3348 (scm_lazy_catch): Rewritten to use it.
3349 (scm_ithrow): Handle the new lazy catch representation.
3350 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3351 that doesn't have a jmpbuf is a lazy catch clause.
3352 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3353 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3354 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3356 (scm_init_throw): Register the new lazy-catch smob type.
3357 * throw.h (scm_internal_lazy_catch): decl for new function.
3359 * throw.c (scm_internal_catch): Doc fixes.
3361 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3362 configure.in. Including this might cause problems if applications
3363 that link against libguile include their own copies of alloca, but
3364 if they're using autoconf, they should be adding libguile to LIBS
3365 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3366 the copy in libguile, and things will be okay. (I think.)
3368 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3370 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3372 strop.h: move prototypes too.
3374 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3376 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3379 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3380 etc. I deleted them from filesys.c long ago, but didn't
3381 notice they were here too (although ineffective since
3382 sys/stat.h wasn't included).
3384 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3386 * eval.c: Don't define alloca in GCC case. gcc will automatically
3387 use __builtin_alloca if appropriate.
3389 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3391 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3392 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3393 that values of automatic variables are preserved. See comments
3394 for safe_setjmp for details.
3396 Change from Thomas Morgan:
3397 * variable.c: Include eq.h.
3398 (var_equal): New function.
3399 (variable_smob): Use var_equal as the discriminator for variables.
3401 * throw.c (s_throw): Remove extraneous declaration.
3403 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3404 * eval.c: Add necessary CPP cruft to support that.
3405 * configure, Makefile.in, scmconfig.h.in: regenerated.
3407 Change from Thomas Morgan:
3408 * procprop.c (scm_procedure_properties): Convert the Scheme
3409 boolean returned by scm_procedure_p into a C boolean before using
3410 it as a condition for SCM_ASSERT.
3411 (scm_procedure_property): Likewise.
3413 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3414 indications of Unixness.
3417 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3419 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3421 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3423 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3424 "unknown # object" error messages.
3426 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3427 (scm_i_index) and declare it static. Add a 'direction' argument
3428 to indicate what way the search should go.
3429 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3431 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3432 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3434 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3436 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3438 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3439 to avoid clash with various scsh forks.
3441 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3443 The following two changes (ramap.c, throw.c) are motivated by the
3444 apparent unportability of forward declarations of static arrays of
3445 the form `static foo bar[];'.
3447 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3448 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3450 * throw.c (scm_throw): Moved above scm_ithrow.
3452 * options.h: Removed the extern declarations of scm_yes_sym and
3453 scm_no_sym since these are static.
3455 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3457 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3459 * Makefile.am: remove AWK=@AWK@.
3460 Add a rule for generating errnos.list.
3461 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3463 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3464 don't extract errnos, just set a variable (avoids the
3465 need to recompile error.c just because configure is run.)
3467 * unif.h: update prototypes.
3468 * unif.c (scm_uniform_array_read,write): change the offset and
3469 length arguments to start and end, for consistency.
3471 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3473 * ioext.h: update prototypes.
3474 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3475 scm_read_line_x, it's a more general procedure using an
3476 interface from scsh. read-line and read-line! are now defined
3478 Note that the new read-line trims the terminator
3479 by default, previously it was appended to the returned string. An
3480 optional argument specifies how to process the terminator (scsh
3481 compatible). For the old behaviour: (read-line port 'concat).
3482 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3483 returns a pair, but is converted to multiple values if the scsh
3486 socket.h: update prototypes.
3487 * socket.c (scm_recvfrom): for consistency with other procedures,
3488 take start and end as separate optional arguments.
3489 (scm_recv, scm_recvfrom): don't allow the second argument
3490 to be a size, only a buffer. Change the scheme names to
3491 recv! and recvfrom!. Don't return the buffer.
3493 * ioext.h, posix.h: move prototypes too.
3494 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3495 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3496 "read.h" and "unif.h".
3497 * ioext.c: include "chars.h"
3499 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3501 * dynl.c: The dynamic linking and module registration functions
3502 are now defined even when dynamic linking is not available for the
3503 host system. Some of their functionality can be done without
3504 dynamic linking; when it's really needed, they throw errors.
3506 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3508 * configure.in: Only define DYNAMIC_LINKING when one of the system
3509 dependent functions is detected.
3510 * dynl.c (scm_dynamic_func): New function to get the address of a
3511 function in a dynamic object.
3512 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3513 produced by scm_dynamic_func as the thing to call.
3515 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3517 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3518 (scm_register_module_xxx, scm_registered_modules,
3519 scm_clear_registered_modules): New functions.
3521 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3523 * symbols.c (scm_sysintern): Renamed to
3524 scm_sysintern_no_module_lookup.
3525 (scm_sysintern): New function to take the place of the old
3526 scm_sysintern. It uses the current toplevel lookup closure to give
3527 the symbol its value. This is a temporary hack to put packages
3528 like gtcltk into their own module.
3529 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3530 us whether `scm_top_level_lookup_closure_var' has been initialized
3532 * eval.c (scm_init_eval): Set it.
3534 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3536 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3537 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3539 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3541 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3542 scm_sys_dup): deleted: FD capability will be added to other
3544 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3545 scm_fd_free, fd_smob, scm_intern_fd.
3546 (scm_open): renamed from scm_sys_open. Return a port instead of
3547 an FD object. Make the mode argument optional.
3548 (scm_sys_create): deleted, it's just a special case of open.
3549 (scm_init_filesys): move interning of constants O_CREAT etc.,
3550 here (were previously using SCM_CONST_LONG macro).
3551 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3553 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3554 include "fports.h" and <stdio.h>
3555 (scm_stat, scm_select): don't support FD objects.
3557 * error.h: adjust scm_syserror_msg prototype.
3558 * error.c (scm_syserror_msg): take an extra argument for errno.
3559 Using the global value didn't always work, since it could be
3560 reset by procedure calls in the message or args arguments.
3562 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3563 I don't understand why the check was there (and what about the
3566 * strop.c (scm_string_copy): allow shared substrings to be copied.
3568 * unif.h: corresponding change to prototypes.
3569 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3570 recognize two new optional arguments: offset and length. Allow
3571 the port argument to be an integer (file descriptor, for scsh).
3572 Include <unistd.h> for "read" prototype.
3574 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3576 * socket.c: don't include filesys.h.
3578 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3580 * Makefile.am: add AWK=@AWK@ (?)
3582 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3584 Add a rule to generate errnos.c from errnos.
3585 * error.c (scm_init_error): include errnos.c.
3586 * errnos_cnvt.awk: new file, converts the list of errno codes to
3588 * errnos_get.c: new file.
3589 * errnos.default: new file, contains errnos to try if they can't
3590 be extracted from errno.h.
3591 * configure.in: if using GCC, try and extract errno codes from
3595 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3597 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3598 * Makefile.am: Made libguile into a libtool library.
3599 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3600 Set libtool_libs to indicate that libguile is a libtool library.
3601 See guile/ChangeLog for details.
3602 * .cvsignore: ignore "*.lo", the libtool library objects.
3604 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3606 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3607 use htons in getservbyport argument.
3609 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3611 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3612 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3615 * objprop.c (scm_object_property): No need to take the CDR of the
3616 value returned by scm_object_properties, since Aug 20 change.
3618 * configure.in: When checking for struct linger, #include
3619 <sys/types.h> as well as <sys/socket.h>. I've never known
3620 <sys/types.h> to cause any portability problems, and Solaris's
3621 <sys/socket.h> needs it.
3622 * configure: Rebuilt.
3624 I think the Sun compiler has chosen a perverse way to interpret
3625 ANSI declarations combined with K&R definitions. We'll
3626 appease it a little bit. But when it invades France, we fight.
3627 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3628 * print.h (scm_iprlist): Here too.
3629 * numbers.c (scm_divbigdig): Change definition to match
3630 declaration in numbers.h.
3631 * unif.c (scm_makflo): Change definition to match declaration in
3634 * init.c (scm_boot_guile): Don't return the value of
3635 scm_boot_guile_1. This function doesn't return a value;
3636 scm_boot_guile_1 doesn't return a value (or return at all).
3638 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3641 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3642 compile. I have a feeling this function is a bad idea anyway ---
3643 one should always test for features, not systems.
3645 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3646 semicolons. Only pure luck kept this from being noticed earlier.
3648 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3650 * socket.c (scm_recvfrom): Added missing semicolon.
3652 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3654 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3655 the buffer and start and end positions for scsh networking
3658 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3660 * configure.in: Revert previous change to this file; the problem
3661 is due to transient automake weirdness.
3662 * configure: Rebuilt.
3664 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3665 PLUGIN/guile.libs. configure generates the latter from the former.
3666 * Makefile.in: Rebuilt.
3668 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3669 need this if we install scripts, like guile-snarf.
3670 * configure: Rebuilt.
3672 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3674 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3676 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3678 * socket.c (scm_addr_vector): fix faulty scm_listify.
3680 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3682 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3683 style block comment is no longer considered an error.
3685 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3687 * PLUGIN/guile.libs.in: New file.
3688 * PLUGIN/guile.libs: Removed from repository.
3689 * configure.in: Create PLUGIN/guile.libs from
3690 PLUGIN/guile.libs.in. This is for including additonal libraries
3691 needed for dynamic linking.
3692 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3693 instead of PLUGIN/guile.libs.
3695 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3697 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3699 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3700 occurrences of the given element from the list, not just the
3701 first. This is how the Emacs Lisp functions behave, how the
3702 analogous Common Lisp functions behave, and (I believe) how the
3703 older Maclisp functions worked. I realize that this change may
3704 break code, but it seemed better to break it before the Guile
3707 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3708 Their prototypes were already present in gc.h, but they weren't
3710 (scm_init_storage): Initialize scm_protects.
3711 * root.c (scm_protects): New element of scm_sys_protects.
3713 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3715 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3717 * libguile.h: Added #include "libguile/net_db.h".
3719 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3720 30 change. That file is only meant for communication between the
3721 configuration process and load.c. If code linked against libguile
3722 wants to get at the paths mentioned in libpath.h, it can call
3723 functions declared in load.h.
3725 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3727 * libguile.h: Removed #include "libguile/fdsocket.h"
3729 * net_db.c: Added #include <sys/socket.h>.
3731 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3733 * filesys.c (scm_input_waiting_p): use select in preference to
3734 FIONREAD, since the latter doesn't detect EOF.
3735 Throw error if neither select nor FIONREAD available.
3737 * socket.c (scm_connect): take a port, not a fd object.
3738 (scm_fill_sockaddr): throw an error if fam is not recognised.
3739 (scm_bind): use scm_fill_sockaddr.
3740 (scm_listen): take a port, not a fd object.
3741 (scm_accept): take and return a port. return #f in the car if
3742 address can't be got
3743 (scm_sock_fd_to_port): new procedure.
3744 (scm_socket): use scm_sock_fd_to_port.
3745 (scm_addr_vector): throw error if unrecognised address type.
3746 take an extra argument with the calling procedure name.
3747 (scm_getsockname): take a port. return #f if address can't be got.
3748 (scm_getpeername): take a port. return #f if address can't be got.
3749 (scm_recvfrom): take a port. return #f for address component if can't
3751 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3752 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3754 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3756 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3757 use separate data pointers, to allow them to be designed
3758 independently and reused.
3759 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3760 Renamed from catch_body, catch_handler, and uncaught_throw; made
3762 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3764 (scm_catch): Use the above.
3765 (scm_throw): Don't bother printing a message for an uncaught
3766 throw; we establish a default handler in init.
3767 * throw.h (scm_internal_catch): Prototype updated.
3768 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3770 (struct scm_body_thunk_data): New structure, used as data
3771 argument to scm_body_thunk.
3772 * init.c (struct main_func_closure): New structure, packaging up
3773 the data to pass to the user's main function.
3774 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3775 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3776 scm_internal_catch to establish a catch-all handler, using
3777 scm_handle_by_message. This replaces the special-case code in
3779 (invoke_main_func): Body function for scm_internal_catch; invoke
3780 the user's main function, using the main_func_closure pointer to
3781 decide what to pass it.
3782 * root.c (struct cwdr_body_data): Remove handler_proc member.
3783 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3784 (cwdr_handler): Removed.
3786 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3788 * socket.h (SCM_P): update bind prototype.
3789 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3790 include "feature.h".
3791 (scm_socket): return a port, not a file descriptor object.
3792 include "fports.h" and <unistd.h>
3793 (scm_bind): take a port, not a file descriptor object.
3794 take an extra argument for address args.
3796 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3797 INADDR_NONE, INADDR_LOOPBACK.
3799 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3801 * init.c: include net_db.h and not fdsocket.h.
3802 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3804 * Makefile.am: corresponding changes.
3805 * socket.h: renamed from fdsocket.h, fix names.
3806 * net_db.h: renamed from socket.h, fix names.
3807 * socket.c: renamed from fdsocket.c.
3808 remove _sys from procedure names.
3809 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3810 add "socket" to features list.
3811 * net_db.c: renamed from socket.c.
3812 remove _sys from procedure names.
3813 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3814 add "net-db" to features list.
3815 include "net_db.h". don't include <sys/socket.h> or
3818 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3820 * tags.h (scm_tags): Removed comma at end of last enumerator.
3822 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3824 Don't use GCC extensions to allocate space for debugging frames.
3825 (Here he goes again! Why do we put up with this?!)
3826 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3827 an scm_debug_info structure, not an in-line array of them. Add
3828 'info' member, to say how many vect elements we've used, for eval
3830 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3831 a new variable debug_info_end to mark the end of vect, instead of
3832 the address of the 'info' pointer itself.
3833 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3834 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3835 (SCM_APPLY): Explicitly allocate space for debug.vect.
3836 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3837 * stacks.c: Adjusted for new debug frame structure.
3838 (RELOC_INFO, RELOC_FRAME): New macros.
3839 (stack_depth, read_frames): Use them, and new scm_debug_frame
3840 element 'info', instead of magically knowing that eval frames have
3841 an info pointer sitting after vect.
3842 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3844 (scm_init_stacks): Formatting tweaks.
3846 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3848 Give GCC more control flow information, so it can be sure that
3849 variables aren't used uninitialized.
3850 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3851 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3852 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3853 scm_misc_error): Tell GCC that these functions never return.
3854 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3855 out the field type, call abort if SCM_ASSERT returns, to placate
3857 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3858 scm_wta ever returns. We can't handle this case anyway, and this
3859 gives the optimizer more information.
3860 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3861 scm_wta ever returns.
3863 In some cases, the code is fine, but GCC isn't smart enough to
3864 figure that out; this usually happens when one variable is only
3865 initialized and used when a particular condition holds true, and
3866 we know that condition will never change within a given invocation
3867 of the function. In this case, we simply initialize the variables
3868 to placate the compiler, hopefully to a value which will cause a
3869 crash if it is ever actually used.
3870 * print.c (scm_iprin1): Initialize mw_pos.
3871 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3872 * throw.c (scm_ithrow): Initialize dynpair.
3873 * unif.c (scm_uniform_vector_ref): Initialize cra.
3874 * struct.c (init_struct): Initialize prot.
3875 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3877 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3878 if EXPR contains no expressions.
3880 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3882 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3883 cause an infinite loop (???). So much for the algebraic
3884 equivalency of variable-sized arrays and alloca...
3886 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3888 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3889 a SCM boolean, not a C boolean.
3891 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3893 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3894 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3895 rules for raising scm_mtrigger. Previously, unfortunate but not
3896 unlikely circumstances could result in almost constant invokation
3897 of the gc. Now, this situations should be less likely, but they
3898 are not prevented completely.
3900 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3902 * numbers.c (scm_fuck): Procedure removed; looks like old test
3904 * numbers.h: Prototype removed.
3906 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3908 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3909 array to a pointer, to match my Nov 21 change in eval.c.
3911 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3913 * libguile.h: Added #include "libguile/backtrace.h", #include
3914 "libguile/stacks.h".
3916 * strings.c (scm_string scm_make_string scm_string_ref
3917 scm_string_set_x scm_string_equal_p scm_string_append):
3918 Bugfix according to scm patch from Aubrey Jaffer:
3919 Corrected long-standing
3920 (not (eqv? (integer->char 128)
3921 (string-ref (make-string 1 (integer->char 128)) 0)))
3922 bug found by John Kozak <jk@noontide.demon.co.uk>.
3924 * strports.c, strports.h: Make scm_eval_0str return the value of
3925 the last expression evaluated (previously, it returned void).
3927 * strports.c, strports.h: New function: scm_read_0str. Does what
3930 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3932 * simpos.c (scm_getenv): return #f if string can't be found in the
3933 environment instead of throwing an exception, for compatibility
3934 with numerous other systems.
3936 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3938 * Makefile.am (.c.x): Use guile-snarf.
3939 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
3941 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
3943 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3945 * backtrace.c (scm_display_error_message): Made non-static, and
3946 renamed from display_error_message.
3947 * backtrace.h (scm_display_error_message): Added extern decl.
3948 * throw.c (uncaught_throw): Use it to display the error message.
3950 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
3952 * inet_aton.c: Use #if 0, not #ifdef 0.
3954 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
3956 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
3957 to convert the returned value.
3958 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
3959 the offset argument.
3961 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3963 Add new interface to catch/throw, usable from C as well as
3965 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
3966 (scm_internal_catch): New function, replaces...
3967 (scm_catch_apply): Deleted.
3968 * throw.c (scm_catch_apply): Deleted; replaced with a more general
3969 mechanism which is a bit more code, but can be used nicely from C
3970 and implement the Scheme semantics as well.
3971 (scm_internal_catch): This is the replacement; it's named after
3972 the analogous function in Emacs.
3973 (scm_catch): Reimplemented in terms of the above.
3974 (struct catch_body_data, catch_body, catch_handler): New
3975 functions, used by scm_catch.
3976 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
3977 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
3978 support for new cwdr.
3980 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
3983 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
3985 * acconfig.h: Added DYNAMIC_LINKING symbol.
3986 * configure.in: Add option and checks for dynamic linking.
3987 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
3988 dynl.h: New files for dynamic linking support.
3989 * Makefile.am (libguile_a_SOURCES):
3991 (modinclude_HEADERS): Added "dynl.h".
3992 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
3994 * init.c (scm_boot_guile_1): Call
3995 scm_init_dynamic_linking to initialize dynamic linking support.
3997 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
3999 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
4000 (as we Schemers say). It needs to be global, so that I can tweak
4001 it for the proper operation of unexec.
4002 (scm_boot_guile_1_live): New variable, see above.
4004 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
4006 * guile-snarf.sh: Removed.
4007 * PLUGIN/guile.libs: Added dependency for -lm.
4008 * acinclude.m4: Renamed from aclocal.m4.
4009 * PLUGIN/greet: Removed.
4010 * Makefile.am, aclocal.m4: New files.
4011 * configure.in: Updated for Automake.
4013 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
4015 * eval.c (scm_definedp): Use top_level_lookup_closure_var
4016 and not top_level_lookup_thunk_var.
4018 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
4020 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
4022 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
4024 * eval.c (scm_definedp): Incompatibly changed to be a builtin
4025 Scheme function, instead of syntax. Single argument is now a
4028 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4030 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
4031 scm_ra_divide): Properly terminate statements passed as arguments
4032 to IVDEP macros. (Thanks to Bernard Urban.)
4034 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
4035 with non-constant sizes. (Thanks to Bernard Urban.)
4037 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4039 It's an "eval closure", not an "eval thunk." A thunk is a
4040 function of no arguments.
4041 * root.h (struct scm_root_state): Renamed
4042 top_level_lookup_closure_var from top_level_lookup_thunk_var.
4043 (scm_top_level_lookup_closure_var): Renamed from
4044 scm_top_level_lookup_thunk_var.
4045 * root.c (mark_root): Uses changed.
4046 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
4047 * init.c (scm_start_stack): Uses changed.
4048 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
4049 Change scheme-visible name to *top-level-lookup-closure* from
4050 *top-level-lookup-thunk*.
4052 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
4054 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
4055 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
4057 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
4059 * gc.c (struct scm_heap_seg_data): Doc fixes.
4061 * gc.c (scm_gc_sweep): Empty all segments' freelists before
4062 sweeping. Then, prepend each segment's free cells to its
4063 freelist, rather than wiping out the old value. (Thanks to Marius
4066 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
4067 scm_check_freelist, scm_debug_newcell): New functions and
4068 variables, for debugging freelist problems.
4069 * pairs.h (SCM_NEWCELL): New debugging version added.
4070 * gc.h (scm_debug_newcell): Added extern declaration, used by
4071 debugging version of SCM_NEWCELL.
4073 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4075 On some systems <libc.h> conflicts with <unistd.h>, and should not
4076 be #included at all.
4077 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
4078 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
4079 * configure.in: Call it.
4080 * posix.c, filesys.c: Use its results to decide whether or not to
4082 * configure, scmconfig.h.in: Rebuilt with autoconf and
4085 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4087 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
4088 pointer to the stdio stream before calling scm_setbuf0, so the
4089 latter will be able to retrieve it. I'm surprised this didn't
4090 segfault earlier. (Thanks to Christopher Lee.)
4092 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4094 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
4097 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4099 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
4100 number of stack narrowing specifier pairs. The first specifier in
4101 a pair controls inner border, the second the outer border. A
4102 number means cut that number of frames, a procedure object means
4103 cut until that object is found in operator position in a frame.
4105 * root.c (cwdr): Bugfix.
4107 * read.c: Recording of positions disabled by default.
4109 * procs.c (scm_closure_p): New function.
4111 * posix.c (scm_tmpnam): New function.
4113 * load.c: Added #include "throw.h".
4114 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
4117 * load.c, load.h (scm_read_and_eval_x): New function.
4119 * eval.c: Renamed debug option "deval" to "debug".
4121 (scm_eval_x): `eval!' is no longer accessible from the scheme
4122 level. Motivation: We can't allow operations which introduce
4123 glocs into the scheme level. Guile's type system can't handle
4124 these as data. Use `eval' or `read-and-eval!' as replacement.
4126 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
4127 SCM_CONSP since this is a macro!; Set vframe.prev to
4128 scm_last_debug_frame instead of 0. In this way we can look
4129 "above" the virtual start stack frame if we wish.
4130 (scm_debug_hang): New function: Useful for debugging Guile in
4131 certain tricky situations. Will probably be removed later...
4133 * debug.h: Changed semantics of debug option "backtrace". This
4134 option now only indicates whether we want automatic backtrace at
4137 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4139 * ports.c: #include "filesys.h"
4140 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
4142 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
4143 Motivation: This is system specific code which is related to file
4144 I/O. It also may use select. Added code by Gary Houston to
4145 detect presence of character in stdio buffers.
4147 * libguile.h: #include "libguile/libpath.h"
4149 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4150 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4151 SCM_SITE_DIR; Install libpath.h among the other include files.
4153 * load.c, load.h (scm_sys_package_data_dir): New function.
4155 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4157 * stacks.h: Bugfix: Don't use tail-array length field as stack
4158 length field! This screwed GC.
4160 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4162 * _scm.h: Added #ifndef around definition of macros min and max.
4164 * __scm.h: Added hooks for threads to plugin to in ints protection
4165 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4166 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4167 the main code in these macros duplicated and spread over multiple
4168 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4169 SCM_THREAD_SWITCHING_CODE.
4171 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4173 * snarf.h: New file.
4174 * guile-snarf.sh: New file.
4175 * Makefile.in (inner_h_files): Added snarf.h
4176 (ancillary, install, uninstall, distclean): Added actions for
4178 (.c.x): Use guile-snarf.
4179 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4180 (gen_c_files): Note that these depend on guile-snarf.
4181 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4182 now in "snarf.h". Added #include "snarf.h" to get them.
4183 * libguile.h: Added #include "snarf.h".
4184 (Patches applied and tweaked by Jim Blandy.)
4186 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4188 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4189 standards suggest against providing prototypes for system
4190 functions. Thanks to Greg Troxel.
4192 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4194 * strports.c (scm_eval_0str): New function.
4195 #include "read.h", to get prototype for scm_read.
4196 * Makefile.in (strports.o): Update dependencies.
4197 * strports.h: New prototype.
4199 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4200 scheme name from "int?" to "integer?". It seems to do the job.
4201 * numbers.h: Rename prototype too.
4202 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4205 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4206 scm_num_eq_p): Rename these according to R4RS conventions: call
4207 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4208 to making libguile R4RS compliant without ice-9...
4210 * load.c (scm_sys_search_load_path): Search for files under all
4211 extensions listed in the %load-extensions variable. If FILENAME
4212 is absolute, return it unchanged, without searching the load path.
4213 (scm_loc_load_extensions): New variable, pointing to
4214 %load-extensions' value cell.
4215 (scm_init_load): Initialize it, and the value it points to.
4216 (scm_primitive_load_path): Improve error reporting.
4218 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4219 of new Scheme variable %load-hook.
4220 (scm_primitive_load): Apply %load-hook to filename.
4222 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4224 * configure.in: add tests for figuring out whether buffered data
4225 is available in a FILE structure, which is needed by char-ready.
4227 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4230 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4231 exceptions using misc_error instead of syserror. It seems a bit
4232 odd to throw an exception if a string can't be found in the
4233 environment, but it's consistent with open-file, stat etc.
4234 (simpos.h): remove sys_ from getenv.
4236 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4237 occurs, throw an error instead of returning errno. Return value
4239 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4241 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4243 * filesys.c (scm_stat2scm): derive file type and permissions from
4244 the stat mode and append them to the returned vector.
4245 There isn't much overhead in doing this and it avoids the need to
4246 work with S_IRUSR et al. in Scheme.
4247 Define symbols scm_sym_regular etc.
4248 (scm_init_filesys): don't intern S_IRUSR etc.
4250 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4251 and s_primitive_load_path.
4253 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4255 * error.h: don't declare error symbols. prototype for scm_misc_error.
4257 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4260 * error.c: use SCM_SYMBOL to set up error keys.
4261 scm_misc_error: new procedure.
4263 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4265 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4266 between `#!' and `!#' is ignored.
4267 (skip_scsh_block_comment): New function.
4269 * feature.c (scm_set_program_arguments): New argument, FIRST.
4270 * feature.h: Update prototype.
4271 * init.c (scm_boot_guile_1): Pass new argument to
4272 scm_set_program_arguments.
4274 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4276 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4277 (scm_boot_guile): Call scm_set_program_arguments here, later than
4278 the old initialization.
4280 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4281 initialization procedure.
4282 - Delete in, out, err arguments; there are other perfectly good
4283 ways to override these when desired.
4284 - Delete result argument; this function shouldn't ever return.
4285 - Rename init_func argument to main_func, for less confusion.
4286 - Delete boot_cmd argument; main_func is more general.
4287 -Add 'closure' argument, to help people pass data to main_func
4288 without resorting to global variables.
4289 - Abort if reentered; don't bother returning an error code.
4290 - Call scm_init_standard_ports to set up the default/current
4291 standard ports; no need to pass them to scm_start_stack.
4292 - Remove code to evaluate the boot_cmd, and start the repl; let
4293 the user do something like that in main_func if they want.
4294 - Remove code to package up a return value; main_func can do any
4296 - Call exit (0), instead of returning.
4297 (scm_start_stack): Don't initialize the I/O ports here; that's
4298 weird. Delete in, out, err arguments. Move guts to
4299 scm_init_standard_ports, scm_stdio_to_port.
4300 (scm_init_standard_ports): New function, to set up current and
4301 default standard ports.
4302 (scm_start_stack, scm_restart_stack): Make these static.
4303 * init.h (scm_boot_guile): Adjust declaration.
4304 (scm_start_stack, scm_restart_stack): Remove externally
4305 visible declarations for these.
4306 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4308 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4309 written out several times in scm_start_stack.
4310 * fports.h: New declaration for the above.
4312 * feature.c (scm_set_program_arguments): New function.
4313 * feature.h: New declaration for the above.
4315 * ports.c: Formatting tweak.
4317 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4319 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4320 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4321 for obtaining the address of a car or cdr field. Motivation:
4322 &SCM_CXR make assumptions about the internal structure of the
4325 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4326 Motivation: see SCM_CXRLOC.
4328 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4329 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4330 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4331 Motivation: Safer use. Some other macros are defined in terms of
4332 these operations. If these are defined using the SCM_SETCXR
4333 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4334 to inefficiency and an <e1> with side-effects could potentially
4335 break. Also, these particular operations are heavily utilized in
4336 the garbage collector. In unoptimized code there will be a
4339 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4340 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4341 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4342 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,

4344 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4345 vports.c: Cleaned up use of pairs: Don't make any special
4346 assumptions about the internal structure of selectors and
4347 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4348 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4349 (Among other things, this change makes it easier to build Guile
4350 with certain compilers which have problems with casted lvalues.)
4352 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4354 * stacks.c: Improve selection of relevant stack frames when making
4355 a stack object. Introduce one level of indirection in the stack
4356 object to make it possible to "narrow" to a certain region of the
4357 stack. This facilitates making use of more clever algorithms (not
4358 implemented) for selecting relevant frames and gives a cleaner
4359 design since selection of frames can be done independently of
4360 extraction of frames from the real stack.
4361 (scm_stack_id): Also take #t as argument which means look at
4364 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4365 Turn n_tail into an integer directly representing current number
4366 of frames in stack. Add field tail.
4368 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4370 * debug.c (scm_make_memoized): Made it available at scheme level.
4371 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4372 SCM_NIMP before applying heavier predicates in argument checking.
4373 (scm_local_eval): Also take memoized object as argument.
4375 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4376 aren't created with zero length, but should such a strange
4377 creature suddenly turn up...
4379 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4381 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4382 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4384 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4386 * variable.c (scm_make_variable): Make the name hint optional, as
4388 (anonymous_variable_sym): Renamed from variable_sym. All uses
4391 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4392 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4393 of scm_primitive_load_path was also changed to
4394 "primitive-load-path", from "%try-load-path". Callers changed.
4395 We'd like to respect the convention that a function named
4396 "try-mumble" should behave just like the function called "mumble",
4397 but return #f instead of signalling some error.
4398 * load.h: Rename prototypes.
4400 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4402 * print.c (make_print_state, grow_print_state), print.h: Modified
4403 the print state representation: Don't use a tail array for
4404 recording of circular references. Resizing of the print state
4405 structure invalidates the print state pointer. To avoid passing
4406 around an indirect print state reference to all printing
4407 functions, we instead let the print state reference a resizable
4410 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4412 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4413 Don't crash when passed an improper list terminated by a
4414 non-immediate value.
4416 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4418 Allocate data for structures on an eight-byte boundary, as
4419 required by the tagging system.
4420 * struct.c (alloc_struct): New function.
4421 (scm_make_struct, scm_make_vtable_vtable): Call it.
4422 * struct.h (scm_struct_n_extra_words): Bump to 3.
4423 (scm_struct_i_ptr): New "field".
4424 * gc.c (scm_gc_sweep): When we need to free the data, use the
4425 information stored by alloc_struct to find the beginning of the
4426 block allocated to the structure, so we can free it.
4428 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4430 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4433 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4434 (scm_debug_info): New member: id.
4436 * stacks.c: Stacks are now represented as structs; Stacks have an
4437 id given to them by `start-stack'.
4438 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4440 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4441 Changed stack representation.
4443 * debug.c (scm_procedure_name): Try procedure property `name' for
4444 compiled closures aswell.
4446 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4448 * eval.c: scm_i_name moved to gsubr.c
4449 (scm_m_define): Record names of all kinds of procedure
4450 objects. (Earlier, only closures were recorded.)
4452 * procprop.h: Added declaration of scm_i_name.
4454 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4455 (scm_make_gsubr): Record names of compiled closures.
4457 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4459 * debug.c, debug.h: Removed obsolete code.
4461 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4462 stacks.c: Renamed regs --> scm_contregs.
4464 * print.c (scm_free_print_state): Cleanup print state before
4465 returning it to pool. It is better to do it here than in
4466 scm_prin1 since scm_prin1 is called often.
4468 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4469 s_set_source_property_x): Check that first argument is a pair or a
4472 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4473 scm_i_line, scm_i_column and scm_i_breakpoint global.
4475 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4476 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4479 * debug.h: Added debug object smob declaration and macro
4482 * configure.in: Build with backtrace.o and stacks.o if debug
4485 * Makefile.in: Added entries for new files: backtrace.c,
4486 backtrace.h, stacks.c and stacks.h.
4488 * symbols.c (scm_sym2ovcell): Fixed documentation.
4490 * _scm.h (min, max): Added.
4492 * async.c: Moved `min' macro to _scm.h.
4494 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4495 SCM_BACKTRACE_INDENT.
4497 * eval.c: Added new debug options `maxdepth' and `indent'.
4499 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4501 * print.h: Added selector SCM_PRINT_STATE.
4503 * print.c: New functions: scm_make_print_state,
4504 scm_free_print_state.
4506 * print.h: Added declarations for scm_make_print_state,
4507 scm_free_print_state.
4509 * debug.c (scm_m_start_stack): New acro.
4511 * debug.h: Small cleanup.
4513 * init.c (scm_boot_guile_1): Moved scm_init_debug below
4516 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

4536 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
4537 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
4538 declare functions with prototypes. (Patch thanks to Marius
4541 More prototype-related changes from Marius Vollmer:
4542 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4543 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4544 * ports.h (ptobfuns): Added prototypes. This means some casting in
4546 * fports.c: Added casts for initializations, since the functions
4547 are defined to take FILE * as their stream argument, not SCM.
4548 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4549 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4550 to `char *str_data' to conform to prototype.
4552 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4554 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4556 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4558 * stime.c, stime.h: use SCM_P method.
4560 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4562 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4563 be given at least two arguments. Insist that lst's last element
4564 be a list, but don't make any requirements of its predecessors.
4566 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4568 * eval.c (scm_nconc2last): Revert last change; there seems to be
4569 other stuff going on here.
4571 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4573 * eval.c (scm_nconc2last): Make sure that each element of lst
4574 (which is a list of argument lists, except for the tail) is a
4575 proper list, i.e., finite and terminated by '().
4577 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4579 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4582 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4583 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4586 * vectors.c (scm_make_vector): Fill vectors with the undefined
4587 value, to help make Guile Scheme code more portable to other
4590 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4591 * symbols.h, tags.h: Doc fixes.
4593 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4595 * async.c (scm_take_signal): Doc fixes.
4597 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4599 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4600 want to subtract it from the modulus; we just want to leave it
4603 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4605 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4608 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4610 * throw.c (scm_catch_apply): Finished implementation of
4613 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4615 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4617 (scm_init_filesys): set "i/o-extensions" feature.
4620 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4622 * Makefile.in (root.o): Correct dependencies.
4624 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4626 * Makefile.in: Added dependency entry for root.o.
4628 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4629 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4631 * init.c (scm_start_stack): Set initial root continuation number
4634 * procs.c: New function: scm_thunk_p.
4636 * procs.h: Added declarations of scm_thunk_p.
4638 * root.c: Renamed `call-with-new-root' -->
4639 `call-with-dynamic-root'.
4640 (cwdr): Removed allocation of new root state. This should be done
4641 separately by use of scm_make_root.
4642 (scm_apply_with_dynamic_root): New function: Does what it
4643 sounds like. Needed when spawning threads.
4645 * root.h: Added member last_debug_frame to root state.
4646 Added #include "libguile/debug.h"
4648 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4649 arguments. The motivation is that code in root.c needs catch
4650 functionality, and we want to avoid code duplication.
4651 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4652 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4653 handlers that run without popping the stack into the dynwind
4656 * throw.h: Added prototypes for scm_catch_apply and
4659 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4661 * root.h (scm_root, scm_set_root): Decouple thread support details
4662 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4663 SCM_SET_THREAD_LOCAL_DATA.
4665 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4666 and tortoise scanning loop.
4668 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4670 * Makefile.in: Rebuild dependencies.
4672 * libguile.h: #include "libguile/print.h" before "smob.h", since
4673 the latter uses the print_state structure.
4675 * throw.c (scm_ithrow): Use the correct variable when checking to
4676 see if a given element of scm_dynwinds is a valid catch.
4678 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4679 structure, abort; don't just silently ignore the garbage.
4681 * _scm.h: #include "print.h" here, since it seems to be used just
4683 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4684 strports.c, unif.h: Don't #include "print.h".
4686 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4688 * feature.h (scm_loc_features): Removed external declaration.
4689 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4691 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4693 * feature.c (scm_init_feature): Added threads feature (needs to be
4694 initialized here, since features doesn't exist when
4695 scm_init_threads is called).
4697 * libguile.h: Added #include "libguile/../threads/threads.h".
4698 (This is a kludge to get thread support working. This should be
4701 * configure.in, acconfig.h: Added flags for thread support.
4703 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4706 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4707 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4710 * _scm.h: Added conditional #include "threads.h"
4712 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4713 SCM_THREADS_SWITCHING_CODE.
4715 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4716 allocate the basic dynamic root object.
4717 (scm_boot_guile): Added call to scm_init_root.
4719 * root.c, root.h: Added root smob.
4720 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4721 functions: Implements dynamic roots mostly according to spec in
4722 SCM manual. Main difference is that the second argument is a
4723 throw handler rather than an error "thunk".
4725 * root.h: Added declaration of scm_init_root.
4727 * root.c: Added #include "genio.h", #include "smob.h", #include
4728 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4730 (scm_init_root): Added #include "root.x".
4732 * throw.c: Added #include "stackchk.h"
4733 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4734 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4735 can be used in scm_call_with_new_root; Added reenabling of stack
4736 checking when catching a throw.
4738 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4740 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4742 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4743 element is not found, as per R4RS.
4745 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4747 * list.c: Doc fixes throughout.
4749 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4751 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4752 declare the char * to be const. Avoids a warning in rgx.c.
4754 * ports.h: spelling fix.
4756 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4759 * load.c (scm_sys_try_load_path): throw an error if file not found
4760 (like it says it in NEWS).
4762 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4764 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4765 PROPS slot to '(), not #f; it's an empty alist.
4767 * throw.h, throw.c: Use SCM_P instead of #if hair.
4769 Remove special support for uncaught throws; see throw.c for
4771 * throw.c (uncaught_throw): New function.
4772 (scm_ithrow): Call uncaught_throw if we don't find a throw
4773 target; don't mess with scm_bad_throw_vcell.
4774 (scm_bad_throw_vcell): Variable deleted.
4775 (scm_init_throw): Don't initialize it.
4777 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4780 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4782 * numbers.c (scm_istr2int): If the number is short (as most
4783 numbers are), just call scm_small_istr2int to deal with it.
4784 (scm_small_istr2int): New function, created by un-#ifdefing the
4785 non-bignum version of scm_istr2int and renaming it.
4787 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4789 * load.c (scm_sys_try_load): don't check whether value returned
4790 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4791 Change the Scheme name from %try-load to primitive-load.
4793 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4794 Can avoid passing a message, allowing it to be derived in the
4795 error handler (e.g., if we want to throw to the key both from
4798 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4800 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4801 references now have a new appearance which is more compact and
4802 also gives a clue about what the target of the reference is.
4803 By setting parameters in the print state, more fancy printing can
4804 be achieved. This is used by the (not yet commited) backtrace
4807 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4809 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4812 * print.c: Added #include "struct.h". Removed function
4815 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4816 scm_iprin1. Removed prototype for scm_prlist.
4818 * arbiters.c (prinarb),
4819 async.c (print_async),
4820 debug.c (prindebugobj, prinmemoized),
4821 eval.c (prinprom, prinmacro),
4822 filesys.c (scm_fd_print, scm_dir_print),
4824 mallocs.c (prinmalloc),
4825 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4826 smob.h (scm_smobfuns),
4827 srcprop.c (prinsrcprops),
4829 unif.c, unif.h (scm_raprin1, rapr1),
4830 variable.c (prin_var): Changed argument `int writing' to
4831 `scm_print_state *pstate'.
4833 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4834 that it will be called before scm_init_print.
4836 * print.c (scm_prin1): Print states are now allocated when calling
4837 scm_prin1 and then passed around to all printing functions as an
4838 argument. A cache `print_state_pool' enables reuse of print
4840 (scm_make_print_state): New function.
4841 (scm_iprin1): Adaption to print states.
4842 (scm_iprlist): An initial "hare and tortoise" scan brings down
4843 time complexity to O (depth * N). (Better time complexity will be
4844 achieved when the printing code is completely rewritten.)
4846 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4848 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4849 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4850 it gets done whether or not the cache variable has a value.
4852 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4854 Distinguish #f and ().
4855 * __scm.h: #undef SICP.
4856 * pairs.h (SCM_EOL): Delete this definition, equating it with
4858 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4859 the value it used to have. Doc fixes, too.
4861 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4863 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4864 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4865 Lord's implementation of structs, allowing for tail arrays as
4866 described in the manual. Also fixed some bugs. (Both the interface
4867 and the implementation should be improved.)
4869 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4871 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4872 People who whish to see the source can do `(print-enable 'source)'.
4873 Removed #ifdef DEBUG_EXTENSIONS.
4875 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4877 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4878 integer (assuming for now accepting an integer is a good thing).
4880 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4881 %S will be used instead for write'ing arguments.
4883 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4884 asserts. fix a few other asserts.
4885 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4886 scm_uniform_vector_ref, scm_array_set_x,
4887 scm_dimensions_to_unform_array): change args in
4888 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4889 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4890 scm_substring_fill_x): likewise.
4891 gsubr.c (scm_gsubr_apply): likewise.
4892 eval.c (SCM_APPLY): likewise.
4894 * eval.c (4 places): replace scm_everr with lgh_error or
4897 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4898 scm_memory_error): new procedures.
4899 scm_everr: deleted. can use scm_wta, dropping first two args.
4900 scm_error: convert NULL subr to SCM_BOOL_F.
4902 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4905 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4908 * error.c, error.h: new error keys: scm_arg_type_key,
4909 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4911 scm_wta: reimplement using lgh_error instead of scm_everr.
4913 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4915 * gdbint.c: scm_lread now has one more argument.
4917 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4918 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4919 loading source from non-file ports, which, e. g., happens when
4920 using the Emacs interface).
4922 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4925 * read.c: Added code for recording of positions of source code
4926 expressions; New functions: recsexpr, scm_lreadrecparen;
4927 _scm_make_srcprops --> scm_make_srcprops
4928 (scm_flush_ws): Removed updating of positions counters. This work
4929 is already done by scm_gen_getc
4931 * read.h: Added prototype for scm_lreadrecparen
4933 * print.c: Added #include "alist.h"
4935 * eval.c: Added #include "hash.h"
4937 * eq.c: Added #include "ramap.h"
4939 * options.c: Documentation fixes.
4941 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
4942 (scm_init_srcprop): Adjusted size of initial source-whash. Name
4943 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
4944 --> scm_make_srcprops
4946 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
4947 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
4948 function calls in the definition of the whash access macros.
4950 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
4952 * init.c (scm_boot_guile): Add level of indirection to
4953 scm_boot_guile_1() to ensure that stack base pointer is properly
4954 initialized. There was no guarantee that variable i was the
4955 highest/lowest variable on stack (i.e. the call frame of
4956 scm_boot_guile was not completely protected from gc).
4958 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
4960 * ports.h (scm_port_table): put back file_name, it will be used to
4961 support debugging. Undo related changes in fports.c, ioext.c,
4964 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4966 * ports.h (scm_port_table): remove file_name member for now, it seems
4968 * fports.c (scm_open_file): don't set file_name in PTAB.
4969 (prinfport): don't use file_name in PTAB.
4970 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
4971 * ports.c (scm_add_to_port_table): don't intialize file_name.
4972 (scm_port_file_name): remove for now.
4973 * gc.c (scm_gc_mark): don't mark PTAB file_name.
4975 * fports.h (scm_mkfile): prototype deleted.
4976 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
4978 * debug.c, unif.c: use scm_out_of_range instead of
4979 wta for range errors (ASSERT still needs work).
4981 * error.c, error.h (scm_out_of_range): new procedure.
4983 * error.c, error.h (scm_out_of_range_key): new key.
4985 * posix.c (scm_sync): #else was missing.
4987 * error.c, error.h: append _key to names scm_num_overflow and
4990 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
4991 of consing an empty list.
4992 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
4993 of macros, saves code and string space.
4994 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
4995 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
4996 lower case. Rename scm_syserror_m to scm_syserror_msg.
4997 error.h: prototypes for new procedures.
4999 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
5001 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
5003 * error.c, error.h: setup scm_num_overflow key.
5005 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
5006 Remove definition of SCM_OVSCM_FLOW.
5008 * fports.c (scm_open_file): use SCM_SYSERROR_M.
5010 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
5011 explicit message and args.
5013 * error.c, error.h, __scm.h: change system_error_sym to
5016 * error.c (system_error_sym): remove leading %% from the Scheme name
5019 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
5021 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5023 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
5024 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
5025 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
5026 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
5027 renamed. (These were introduced by unsupervised name
5030 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5032 * print.c: Added code for detection of circular references during
5033 printing. (init_ref_stack, grow_ref_stack): New functions. Added
5034 a hook for printing of closures (accessible via print options).
5035 This leads to a split of calls to scm_iprin1 into two classes:
5036 elementary print operations (e. g. the code which prints a smob)
5037 still use scm_iprin1 while top level calls (like scm_display) use
5038 scm_prin1. scm_prin1 begins by clearing the data structure used
5039 to record reference information.
5041 * print.h: Added declarations of scm_prin1 and scm_prlist.
5043 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
5045 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
5047 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
5049 * error.c (err_head): scm_iprin1 --> scm_prin1
5051 * debug.c: Adjusted header comment.
5055 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
5057 * strerror.c: Doc fix.
5059 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5061 * gdbint.c (gdb_read): Now possible to run during GC.
5062 (unmark_port, remark_port): New functions.
5064 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
5066 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
5067 of allocating a new string object. Also, increase size by
5068 the factor 2 instead of 1.5.
5070 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
5072 * __scm.h (SCM_P): Corrected to run under traditional C.
5074 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
5077 * async.c: Calls to scm_sysintern corrected.
5079 * async.h (scm_async_clock): Redundant declaration removed.
5081 * continuations.c (scm_dynthrow): Redundant declaration removed.
5083 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
5084 Definition typos corrected.
5086 * debug.h: Missing declarations of functions in debug.c added
5089 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
5090 Missing declarations to functions in eval.c added.
5092 * filesys.c: Possibly uninitialized variable rv.
5094 * gc.h (scm_object_addr, scm_unhash_name): Missing
5095 declarations of functions defined in gc.c added.
5097 * genio.c: Possible typos str_data -> wstr_data. ???
5099 * genio.c: Possibly unintended shadowing of local variable
5100 `int c' (gotos out of scope of inner `c'). ???
5102 * init.c: Uninitialized `SCM last' may be used.
5104 * ioext.h: (scm_sys_isatty_p): Typo.
5106 * list.h (scm_list_head): Missing prototype for function in
5109 * numbers.c (scm_two_doubles): Changed from extern to static
5110 (is used only within numbers.c).
5112 * numbers.h: Repeated declarations removed.
5114 * ports.h (scm_close_all_ports_except): Declaration for the
5115 function defined in ports.c added.
5117 * posix.h: Missing declarations added.
5119 * procs.h (scm_make_subr_opt): Missing declaration added.
5121 * socket.h (scm_sys_gethost): Missing declaration added.
5123 * socket.h: Redundant declarations removed (they are in fdsocket.h).
5125 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
5126 Missing declarations added.
5128 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
5130 * struct.c: Uninitialized variable `SCM answer' may be used.
5132 * unif.c (l2ra): Declaration prototype.
5134 * unif.c (scm_array_equal_p): Dummy definition removed (it is
5135 defined in ramap.c).
5137 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
5138 Redundant declarations removed (they are in ramap.h).
5140 * variable.h (scm_make_udvariable,
5141 scm_make_undefined_variable): Declaration corrected to
5142 correspond variable.c.
5144 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
5145 Missing declarations added.
5147 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5149 * Makefile.in (distclean): Don't forget to delete fd.h.
5151 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5153 * fd.h.in, tags.h: Trivial cleanups.
5155 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5156 marksweep.h just declared functions from gc.c.
5157 * gc.h, libguile.h: Don't #include "marksweep.h".
5158 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5159 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5160 dependencies updated.
5162 * libguile.h: Don't #include "files.h"; it's been deleted.
5164 * files.c (scm_sys_delete_file): Moved to filesys.c.
5165 File is now empty; deleted.
5167 * filesys.c: scm_sys_delete_file is now here. Remove
5168 #if's; they seem to rely on remnants of an old portability
5169 regimen. If the problems come up again, solve them properly,
5170 using autoconf. Specifically: Don't test M_SYSV, and #define
5171 remove to be unlink if it's #defined; don't use remove just
5172 because HAVE_STDC_HEADERS is #defined.
5173 * filesys.h: Add declarations for scm_sys_delete_file.
5174 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5175 files.o, files.h, files.c, and files.x.
5176 * init.c: Don't #include "files.h", and don't call scm_init_files.
5178 Use SCM_P instead of PROTO; the latter intrudes on the user's
5180 * params.h: Deleted; definition of SCM_P moved to...
5181 * __scm.h: ... here, where it replaces PROTO macro.
5182 * libguile.h, smob.h: Don't #include "params.h".
5183 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5184 smob.h: Fix prototypes accordingly.
5185 * Makefile.in: Update dependencies.
5186 (inner_h_files): Remove params.h.
5188 * gc.c: #include "gc.h"; every module should include its header,
5189 to let the compiler cross-check the declarations against the
5192 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5193 simpos.h: #include "libguile/__scm.h".
5195 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5197 * init.c: Don't forget to #include smob.h and init.h.
5198 * Makefile.in: Dependencies updated.
5200 * smob.h: Use PROTO instead of #if __STDC__.
5202 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5204 * __scm.h: Doc fixes.
5206 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5207 <angles>; this allows `make depends' to work properly.
5209 * libguile.h: #include smob.h and pairs.h before the others; they
5210 define typedefs used by other headers.
5212 C files should #include only the header files they need, not
5213 libguile.h (which #includes all the header files); the pointless
5214 recompilation was wasting my time.
5215 * Makefile.in (all .o dependency lists): Regenerated.
5216 * libguile.h: Don't try to get a definition for size_t here...
5217 * __scm.h: Do it here.
5218 * _scm.h: Since this is the internal libguile header, put things
5219 here that all (or a majority) of the libguile files will want.
5220 Don't #include <libguile.h> here; that generates dependencies on
5221 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5222 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5223 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5320 * weaks.c: Get "weaks.h".
5322 * stackchk.h: #include "libguile/debug.h",
5324 * print.h, read.h: #include "options.h", since everyone who uses
5325 either of these files will need that.
5327 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5328 anyone who uses this file will need them to define the smob
5329 printing functions. Also, get markers.h, since people will need
5330 to #define the mark functions.
5332 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5333 * ports.h: ... to here.
5335 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5336 don't rely on archaic C default type rules.
5338 * fports.h: #include "libguile/ports.h", since you need that in
5339 order to parse this.
5341 * genio.h: #include "libguile/print.h", because you need that to
5342 parse this; don't bother #including "ports.h", since print.h gets
5345 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5347 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5348 this; it's now a reference to an element of *scm_root.
5350 * debug.h: Don't #include "options.h"; the compiler won't be able
5351 to find that once the headers are installed; instead, #include
5352 "libguile/options.h".
5353 * gc.h: Same, with marksweep.h.
5354 * mbstrings.h: Same, with symbols.h.
5355 * scmhob.h: Same, with _scm.h.
5356 * smob.h: Same, with params.h.
5358 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5359 C files; there's no need for this, and it forces recompilations
5362 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5364 * error.c (scm_error): declare scm_error_callback.
5366 * error.h: prototype for scm_error_callback.
5368 * __scm.h: define lgh_error.
5369 (SCM_SYSERROR): redefine using lgh_error.
5371 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5373 * error.c (scm_error): new procedure.
5375 * error.h: prototype for scm_error.
5377 * Makefile.in (install): install scmconfig.h from the current
5378 directory, not $(srcdir).
5380 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5382 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5383 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5384 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
5385 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
5386 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
5387 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5388 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5389 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5390 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5391 vports.h, weaks.h: #include "libguile/__scm.h", not
5392 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5393 dependencies are within libguile properly.
5395 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5397 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5398 when scmconfig.h doesn't exist.
5400 * load.c (scm_sys_try_load): Correct spelling.
5402 * feature.c (scm_loc_features): Make this static.
5404 * Makefile.in (libpath.h): Omit trailing slash from path. We
5405 shouldn't require it of users, so why put it here?
5407 Move code to initialize and search %load-path from ice-9 to C
5408 code, so we can use the load-path to find the ice-9 boot code;
5409 this makes it easier to run Guile without installing it. See
5410 corresponding changes in guile/Makefile.in.
5411 * feature.c: Move stuff concerned with the load path to load.c.
5412 (scm_compiled_library_path): Deleted.
5413 Don't #include libpath.h here.
5414 * feature.h: Don't mention scm_compiled_library_path.
5415 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5416 <sys/stat.h>, and <unistd.h> (if present).
5417 (R_OK): #define if the system hasn't deigned to.
5418 (scm_loc_load_path): New variable.
5419 (scm_init_load_path, scm_sys_search_load_path,
5420 scm_sys_try_load_path): New functions.
5421 (scm_init_load): Initialize scm_loc_load_path to point to the
5422 value cell of the Scheme %load-path variable.
5423 * load.h: Add declarations for scm_sys_search_load_path,
5424 scm_sys_try_load_path.
5425 * init.c: Call scm_init_load_path.
5426 * Makefile.in (feature.o, load.o): Dependencies updated.
5428 * load.c, load.h: Rewrite using PROTO macro.
5430 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5432 * gc.c (scm_cellp): New function: C predicate to determine if an
5433 SCM value can be regarded as a pointer to a cell on the heap.
5435 * gc.h: Added declaration of scm_cellp.
5437 * gdb_interface.h: New file: The GDB interface header from the GDB
5440 * gdbint.c: New file: GDB interface.
5442 * gdbint.h: New file: GDB interface.
5444 * libguile.h: Added #include <libguile/gdbint.h>.
5446 * init.c (scm_boot_guile): Added scm_init_gdbint.
5448 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5449 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5450 found if object files and source are kept separate).
5452 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5454 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5456 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5458 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5459 TK_SRC_DIR; they're not relevant any more.
5461 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5462 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5464 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5466 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5467 search path, so we can find the <libguile/MUMBLE.h> headers.
5469 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5471 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5472 implicit in the .c.o rule.
5473 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5476 Put the library path in a header file, instead of passing it on
5477 the command line in every compilation.
5478 * Makefile.in (libpath.h): New target.
5479 (feature.o): Depend on libpath.h.
5480 (clean): Delete libpath.h.
5481 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5482 * feature.c: ... #include "libpath.h" here.
5483 * .cvsignore: Ignore libpath.h.
5485 Don't install the unwashed masses of Guile header files in the
5486 main #include path; put most of them in a subdirectory called
5487 'libguile'. This avoids naming conflicts between Guile header
5488 files and system header files (of which there were a few).
5489 * Makefile.in (pkgincludedir): Deleted.
5490 (innerincludedir): New variable; this and $(includedir) are enough.
5491 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5492 (installed_h_files): Divide this up. Now this variable lists
5493 those header files which should go into $(includedir) (i.e. appear
5494 directly in the #include path), and ...
5495 (inner_h_files): ... this new variable says which files appear in
5496 a subdirectory, and are referred to as <libguile/mumble.h>.
5497 (h_files): List them both.
5498 (install): Create innerincludedir, not pkgincludedir. Put
5499 the installed_h_files and inner_h_files in their proper places.
5500 (uninstall): Corresponding changes.
5501 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5502 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5503 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5504 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5505 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5506 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5507 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5508 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5509 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5510 vports.h, weaks.h: Find __scm.h in its new location.
5511 * __scm.h: Find scmconfig.h and tags.h in their new locations
5512 (they're both "inner" files).
5514 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5516 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5518 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5520 * posix.c: Doc fixes.
5522 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5524 * socket.c: Don't include a prototype for inet_aton; just use a
5525 K&R style declaration, to avoid warnings but minimize the chance
5526 of conflicts with the system.
5528 On NextStep, <utime.h> doesn't define struct utime, unless we
5529 #define _POSIX_SOURCE before #including it.
5530 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5531 * acconfig.h: New comment text for above CPP symbol.
5532 * configure.in: Call it.
5533 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5535 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5537 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5538 testing for __EMX__.
5540 * posix.c: #include <libc.h>, if it exists.
5542 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5543 don't even know if the latter exists.
5545 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5546 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5547 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5549 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5551 (scm_init_posix): Use them when initializing the Scheme constants
5554 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5556 * Makefile.in (libdir, includedir, bindir): Use the
5557 autoconf-supplied values, instead of deriving them ourselves.
5558 (pkgincludedir, datadir, pkgdatadir): New variables.
5559 (install, uninstall): Put the header files in a special
5560 subdirectory, not in the main search path.
5562 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5563 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5565 * Makefile.in (IMPLPATH): Deleted; never used.
5567 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5568 on the Tcl/Tk source any more.
5569 (INCLUDE_CFLAGS): Remove references to the above.
5571 * Makefile.in (version.o): Corrected dependencies.
5573 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5575 * libguile.h: #include "version.h"
5577 * init.c (scm_boot_guile): Call scm_init_version.
5578 * gscm.c (gscm_run_scm): Call scm_init_version.
5580 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5581 GUILE_VERSION): AC_DEFINE these.
5582 (acconfig.h): #undef the above symbols.
5584 * Makefile.in (libobjs): Add version.o.
5585 (installed_h_files): Add version.h.
5586 (c_files): Add version.c.
5587 (gen_c_files): Add version.x.
5588 (version.o): New rule.
5589 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5590 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

5599 weaks.o): Add version.h to dependency lists.
5600 (markers.o): Remove duplicate rule.
5602 * version.h: New file.
5604 * version.c: New file.
5606 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5608 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5609 array; use it appropriately. Since GCC is quite happy to
5610 subscript functions, it never warned us about this; we should use
5611 -Wpointer-arith in the future. I guess we never tested
5614 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5616 * socket.c: Doc and copyright fixes.
5618 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>

5622 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5624 * socket.c: Added declaration of inet_aton to avoid compiler
5625 warning. (Hope this solution is correct.)
5627 * stime.c: Added declaration of ftime. (This is missing in
5630 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5632 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5634 * Makefile.in (c_files): add strerror.c.
5636 * strerror.c: new file from Emacs' sysdep.c.
5637 maybe configure should also check for sys_errlist.
5639 * configure.in (AC_REPLACE_FUNCS): add strerror.
5641 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5643 * debug.c (scm_init_debug): Added initialization for
5644 scm_evaluator_traps.
5646 * debug.h, debug.c: Various name changes.
5647 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5648 "debug-options-interface". See commentary in options.c.
5650 * options.h, options.c: Options now have documentation strings.
5651 Also added a long explanatory commentary.
5653 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5656 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5657 last_debug_info_frame is now updated in all cases.
5659 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5662 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5664 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5665 Added option STACK_CHECKING.
5667 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5669 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5671 * __scm.h: Removed symbols for debugging support.
5673 * acconfig.h: Added symbols for debugging support.
5675 * configure.in: Added user option for debugging support.
5676 --enable-debug will include the debugging code into libguile.a.
5678 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5679 scm_relocate_chunk_to_heap.
5681 * debug.c: New file: low-level debugging support. It also
5682 includes support for debugging with gdb. (The extensions to gdb
5683 are written by Per Bothner at Cygnus.)
5685 * debug.h: New file: low-level debugging support.
5687 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5688 argument pairs. Extensive modifications to the debugging
5689 evaluator. Added "SECTION:" commentaries to clarify what happens
5690 when, during double compilation. Renamed EVALIMP --> EVALIM.
5691 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5692 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5693 the beginning of the file. New procedure: scm_unmemocopy.
5694 Added some global state variables needed by the debugging
5695 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5696 check_entry, check_apply, check_exit, debug_options and
5697 evaluator_traps. New acro: undefine.
5699 * eval.h: Renamed EVAL --> XEVAL.
5701 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5702 --> scm_make_weak_key_hash_table.
5704 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5705 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5707 * libguile.h: Conditionally include debug.h
5709 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5710 scm_object_properties shouldn't return handle. `handle' now gets
5711 initialized in scm_set_object_properties_x. scm_object_properties
5712 doesn't any longer create an entry in scm_object_whash.
5714 * options.c: New file: handling of run time options.
5716 * options.h: New file: handling of run time options.
5718 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5720 * print.c: New procedure: scm_print_options
5722 * print.h: Defines for print options.
5724 * read.c: New procedure: scm_read_options
5726 * read.h: Defines for reader options.
5728 * root.h: Added scm_source_whash among scm_sys_protects.
5730 * srcprop.c: New file: source properties.
5732 * srcprop.h: New file: source properties.
5734 * throw.c (jbsmob): Jump buffers are now correctly allocated.

5737 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5739 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5741 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5743 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5745 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5746 and should be called by the final client.
5748 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5750 * gc.h: Use the PROTO macro when declaring functions.
5751 * gc.c: Use the PROTO macro when declaring static functions.
5752 Remove the CPP hair around function definitions.
5754 * gc.c (scm_init_storage): Initialize scm_asyncs.
5756 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5757 preprocessor symbol; "__scm.h" is where it might get #defined.
5758 * __scm.h: Similar: #include <scmconfig.h> before testing
5761 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5763 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5765 * init.c (scm_boot_guile): Add init_func argument; call
5766 (*init_func) instead of calling scm_appinit; it's ucky to
5767 hard-code names for the user's procedures.
5768 * init.h (scm_boot_guile): Adjust declaration.
5770 * __scm.h (PROTO): New macro, for declaring functions with
5773 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5774 eliminate all the __STDC__ conditionals.
5775 (scm_boot_guile): Add declaration.
5776 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5777 Remove __STDC__ conditionals around function definitions; the
5778 declarations in init.h will provide the same information, more
5781 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5782 complain about it in the error message; the error message is
5783 adequate without that note, and there's nothing the user can do
5786 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5788 * Makefile.in (ancillary): Drop def.sed.
5790 * posix.c (scm_init_posix): Use numeric values, rather than
5791 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5792 F_OK. The symbols aren't available on some systems, and I'm
5793 pretty sure their values are fixed by common widespread practice.
5794 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5796 More functions unavailable on some systems.
5797 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5798 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5800 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5801 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5802 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5803 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5804 stub that signals an error as the #else.
5806 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
5808 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
5810 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
5812 * unif.c: include ramap.h.

5822 * configure.in: check for sys/ioctl.h.
5824 * ports.c: include <malloc.h> not "malloc.h".
5826 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5828 * fports.c: remove ttyname and tmpnam declarations.
5830 * posix.c: fewer ttyname declarations.
5832 * fports.c: include <string.h> not "string.h".
5834 * init.c, ioext.c: include string.h and unistd.h.
5836 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5838 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
5839 genio.c, simpos.c, vports.c: include string.h.
5841 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
5843 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
5845 (scm_addr_buffer_size): change type from scm_sizet to int.
5846 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
5847 from scm_sizet to int.
5849 * error.c: include unistd.h.
5851 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
5854 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
5856 * __scm.hd, def.sed: deleted.
5858 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
5860 Changes for NeXT, suggested by Robert Brown.
5861 * configure.in: Call AC_TYPE_MODE_T.
5862 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
5863 NeXT. Put header file list in alphabetical order.
5864 * configure, scmconfig.h.in: Regenerated.
5865 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
5867 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
5870 * acconfig.h: New file, providing documentation for the CPP
5871 symbols defined in configure.in
5872 * acconfig-1.5.h: Removed; superceded by the above.
5874 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
5876 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
5878 * fports.c (scm_open_file): don't return #f, throw error.
5880 * ioext.c (fileno): renamed from %fileno.
5881 (soft-fileno): deleted.
5883 * ports.c (scm_port_revealed): don't need to check for -1 from
5885 (scm_set_port_revealed_x): return unspecified, not #f.
5887 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
5889 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
5891 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
5893 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
5895 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5897 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5898 This is necessary on Ultrix, and doesn't hurt portability.
5900 * Makefile.in (dist-dir): New target, implementing a new dist system.
5901 (installed_h_files): Put in alphabetical order.
5902 Remove duplicate entries for markers.h and unif.h.
5903 (c_files): Remove duplicate entries for markers.c.
5904 (ancillary): Renamed from anillery; all uses changed. Remove
5905 PLUGIN; it's a directory, and needs special treatment in dist-dir.
5906 Remove all the ../doc/* files; doc/Makefile.in handles that.
5908 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5910 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5911 every if must have an else, or else the whole command has a
5912 non-zero exit code whenever the if's condition is false.
5914 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
5916 * posix.c: include string.h.
5918 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
5920 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
5923 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
5924 Remove leading % from scheme names.
5925 Do not return error values, call SCM_SYSERROR or similar.
5927 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
5929 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
5931 * struct.c (scm_init_struct): new file.
5933 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
5935 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
5936 (scm_list_head): added list-head for rapidly chopping argument
5937 lists off of longer lists (and similar).

5941 * objprop.c (scm_object_property): assq the cdr of the whash
5942 handle for obj, not the handle itself.
5944 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
5946 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
5947 weak hash tables last of all marking to avoid an obscure gc bug.
5948 WARNING: circular lists stored in a weak hash table will hose us.
5950 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
5952 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
5953 new functions similar to scm_substring_move_left_x and
5954 scm_substring_move_right_x.
5956 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
5958 * init.c (scm_boot_guile): prevent gc with scm_block_gc not

5963 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
5965 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
5967 * strports.c (scm_strprint_obj): convenience function. C for
5968 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
5970 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
5971 removed to a separate library
5973 * init.c (scm_boot_guile): copied from guile-tcl.c.
5974 Initialization specific to tcl interpreters removed.
5976 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
5978 * ports.c (scm_ports_prehistory): size malloced here doesn't
5979 matter so long as it is non-0 (got rid of "* 4").
5981 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
5983 * gscm.h: gscm_mkarray eliminated (presumably was not being used
5984 since its definition was bogus).
5986 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
5988 * mallocs.[ch]: back again (for rx at least).
5990 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
5992 * ports.c: removed functions relating to the mapping between ports
5993 and descriptors. (That stuff is unix-specific and should be collected
5994 in a separate library).
5996 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
5997 (Tom Mckay@avanticorp.com)
5999 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
6001 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
6002 handled correctly (SCM_FREEP was applied to them) -- test for
6003 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
6004 being overwritten with #f. (brown@grettir.bibliotech.com)
6006 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
6008 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs

6023 Generalized assoc and hash-table functions.
6024 Factored pairs.c into multiple files.

6036 NOTE: don't use a alist here.
6037 (scm_set_procedure_properties_x): fix type checking throughout this file.

6047 * vports.c (scm_make_soft_port): allocate a port table entry
6048 (possibly triggering gc) before setting the tag of the corresponding
6051 * pairs.c (scm_delq_x): never throw an error.
6053 * vectors.c (scm_make_vector): made the default vector fill argument
6054 into '() (much more useful than the previous value, "#unspecified")
6056 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
6058 * ports.c (scm_add_to_port_table): Added fields
6059 to port table entries: file_name, line_num, col.
6060 Update these in open_file, gen_getc and gen_ungetc.
6061 Added procedures to access those fields.
6063 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
6065 * procs.c (scm_make_subr_opt): new entry point for making

6095 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
6097 * feature.c (scm_compiled_library_path): moved here from repl.c.
6098 This file is for stuff relating specifically to Scheme libraries
6101 * eval.c (scm_m_define): don't give warning about redefinition, don't
6104 NOTE: this should throw a resumable exception with parameters --
6105 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
6107 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
6109 * error.c: scm_warn eliminated.

6129 because it changes size.
6131 (stputc stwrite): check/change the strings length with interrupts
6134 * objprop.c (scm_set_object_property_x &c): use the generic
6135 hashing functions and be threadsafe.

6138 (per suggestion jaffer@gnu.ai.mit.edu).
6140 * mbstrings.c (scm_multi_byte_string): guard against argument list
6143 * strings.c (scm_make_string): loop cleanup

6171 initialization to fix a race condition.
6173 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
6174 object, not in a global.
6175 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)

6194 Thu Feb 15 11:39:09 1996 Tom Lord <lord@beehive>
6196 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
6197 set the multi_byte flag correctly in symbols. This is wrong.
6198 intern_obbary_soft and msymbolize should take an extra parameter.
6199 Also, weird multibyte symbols don't print correctly.
6200 The weird symbol syntax is also a bit bogus (emacs doesn't quite
6203 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
6205 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means
6206 use the system symhash. == #t means create an uninterned symbol.
6208 Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>
6210 * strings.c (scm_make_shared_substring): build'em.
6211 It might better to keep a table of these and use one
6212 less cons-pair per shared-substring.

6282 * lvectors.c (scm_get_lvector_hook):
6283 In guile-ii, the lvector code was broken. It was fixed in guile-iii.
6284 It seems to me like if it is broken again in guile-iv...Here is a patch.
6285 "! || (LENGTH (keyvec) == 0))"
6286 (From: Mikael Djurfeldt <mdj@nada.kth.se>)
6289 * gscm.c (gscm_sys_default_verbosity):
6290 incorrectly declared for non-__STDC__
6291 (Tom_Mckay@avanticorp.com)

6294 to make it easier to port to systems that use
6295 more than a single structure field to hold a descriptor.
6297 * debug.c (change_mode): Avoid GNUCism "int foo[n];"
6298 Give a warning, not an error, for unrecognized modes.
6300 * eval.c (SCM_CEVAL):
