3 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
4 #bytes(...) to #y(...), and syntax for short vectors from
5 #short(...) to #h(...). This may seem nutty, but, like the other
6 uniform vectors, byte vectors and short vectors want to have the
7 same print and read syntax (and, more basic, want to have read
8 syntax!). Changing the read syntax to use multiple characters
9 after the hash sign breaks with the conventions used in R5RS and
10 the conventions used for the other uniform vectors. It also
11 introduces complexity in the current reader, both on the C and
12 Scheme levels. (The Right solution is probably to change the
13 syntax and prototypes for uniform vectors entirely.)
15 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
17 Don't use local_fgets on sockets; ftell doesn't work on sockets.
18 (Thanks to Jorgen "forcer" Schaefer.)
19 * ports.h (SCM_NOFTELL): New flag.
20 * fports.c (local_fgets): If it's set, use the generic fgets.
21 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
23 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
25 * script.c (scm_compile_shell_switches): Add handling of -q switch
26 (inhibit loading of user init file).
27 (scm_shell_usage): Add usage text for -q switch.
28 (scm_compile_shell_switches): Always load user init file first if
31 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
33 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
34 and is now broken under NetBSD. I can't fathom what it's trying
35 to do, so I've replaced it with something that I do understand,
36 which seems to work, and which isn't broken on NetBSD. "Progress?
37 You Decide." (Thanks to Perry Metzger.)
39 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
40 signed/unsigned comparison.
42 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
44 Warning fixes from Greg Harvey:
45 * unif.c (scm_array_set_x): initializer for pos
46 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
47 * struct.c (scm_struct_ref, scm_struct_set_x): Added
48 initializers for field_type, since EGCS so desparately wants to
50 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
51 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
52 when GUILE_DEBUG is defined.
53 * dynwind.h (scm_wind_chain): Same.
54 * ports.h (scm_pt_size, scm_pt_member): Same.
55 * print.h (scm_current_pstate): Same.
56 * procs.h (scm_make_cclo): Same.
58 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
60 Handle short and long long uniform arrays properly. (Thanks to
62 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
63 raeql_1): Add cases for scm_tc7_svect (short vectors) and
64 scm_tc7_llvect (long long vectors).
66 Change the way libguile and boot-9.scm are timestamped, to try to
67 get rid of these spurious mismatch warnings. Now both
68 libguile/versiondat.h and ice-9/version.scm are generated directly
69 by the configuration process, rather than having version.scm
70 generated directly, and libguile/versiondat.h generated by the
71 Makefile, which is generated by configure. It seems that
72 sometimes the Makefile would change, but versiondat.h depends on
73 Makefile.in, not Makefile, so it wouldn't get rebuilt.
74 * Makefile.am (versiondat.h): Target removed; this is generated
75 directly by the configure script now.
76 (BUILT_SOURCES): Remove versiondat.h.
77 * versiondat.h.in: New file, transformed by the configure script
79 * Makefile.in: Regenerated.
81 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
82 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
83 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
84 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
85 if we want to use them in a header file some day, we can. (Thanks
88 * stime.c (scm_get_internal_real_time): Do the arithmetic using
89 SCM numbers, so we won't have rollover problems; the range of a
90 signed long in milliseconds is about 25 days. (Thanks to Karl
93 Don't redefine sleep and usleep; fix this problem now.
94 * coop.c (sleep, usleep): Remove declarations; we don't use or
95 redefine these any more.
96 (scm_thread_usleep, scm_thread_sleep): New functions which do the
97 job of usleep and sleep in a thread-friendly way. We can use
98 these in the rest of Guile. Define versions for systems both with
100 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
101 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
102 we're just using it, not redefining it, we can use a K&R style
104 (sleep): Declare this, too, if the system hasn't.
105 (scm_sleep, scm_usleep): Use scm_thread_sleep and
106 scm_uthread_sleep if they're available; otherwise, just call the
108 * scmconfig.h.in: Regenerated.
110 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
112 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
114 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
116 * threads.c: Doc fix.
118 The argument type of usleep varies from system to system,
119 as does the return type. We really shouldn't be redefining usleep
120 at all, but I don't have time to clean that up before the 1.3.
121 release. It's on the schedule for afterwards. (Thanks to Julian
123 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
125 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
126 * scmconfig.h: Regenerated.
128 * simpos.c (scm_software_type): Procedure deleted. This isn't the
129 right way to handle system variation. Autoconf's approach is the
131 * simpos.h (scm_software_type): Declaration deleted.
133 * script.c (scm_find_executable): Don't test if unix is #defined
134 here; first, NetBSD doesn't #define it, and second, it's the wrong
135 way to go about these things. (Thanks to Perry Metzger.)
136 (dld_find_executable): Delete this MSDOS support code. This isn't
137 the way we want to support this; it needs to be rethunk at a
140 * genio.c (scm_do_read_line): Don't just politely check that the
141 line was either non-empty or EOF. Abort if it's empty and not
144 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
146 * scmconfig.h.in: Regenerated.
148 * libguile.h: Don't omit the dynamic linking functions. (Thanks
151 * genio.c (scm_do_read_line): Count lines correctly when the file
152 doesn't end in a newline.
154 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
156 * genio.c (scm_do_read_line): Maintain the line count correctly.
157 (Thanks to Harvey J. Stein and Greg Harvey.)
159 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
162 * numbers.c (big2str): Protect t from garbage collection until
163 we're done. (Thanks to Gary Houston.)
165 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
167 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
169 * Makefile.in: Regenerated.
171 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
172 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
175 Do magic to mix reads and writes on stdio FILE-based ports.
176 (Thanks to Christian Lynbech.)
177 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
179 (pre_read, pre_write): New functions.
180 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
181 local_fputs): Call them.
182 (local_fflush): Mark the port as ready for reading and writing.
183 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
184 flags on new port objects. This might not be accurate --- who
185 knows what state the FILE * is in when we get it --- but it won't
186 do extraneous calls to fflush or fseek, so it's no worse than the
187 behavior before this change.
188 * ports.h: Add comment.
190 Centralize the creation of port objects based on stdio FILE * in
191 fports.c; don't just throw them together anywhere.
192 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
193 what the rest of Guile wants. Don't set the revealed count;
194 that's only appropriate for stdin, stdout, stderr.
195 (scm_standard_stream_to_port): This function does set the revealed
197 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
198 not scm_stdio_to_port.
199 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
200 * fports.c (scm_open_file): Same.
201 * posix.c (scm_pipe): Same.
202 * socket.c (scm_sock_fd_to_port): Same.
203 * ioext.c (scm_fdopen): Same.
204 (scm_freopen): Moved from here to...
205 * fports.c (scm_freopen): ... here. This is really something that
206 munges the internals of an fport, so it should go here.
207 * fports.h (scm_stdio_to_port): Adjust prototype.
208 (scm_standard_stream_to_port, scm_freopen): New protoypes.
209 * ioext.h (scm_freopen): Prototype removed.
211 * filesys.c (set_element, get_element): This can work on both pipe
212 and file ports, so use SCM_FPORTP to typecheck, instead of testing
215 * scmconfig.h.in: Regenerated.
217 Change the definition of the functions in scm_ptobfuns so that
218 they get passed the port object, not the port's stream.
219 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
220 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
221 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
222 Pass the port itself to the scm_ptobs function.
223 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
224 scm_generic_fgets): Same.
225 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
226 getc_void_port, fgets_void_port, close_void_port): Just change the
227 argument names; these functions don't really do anything.
228 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
229 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
230 port as an argument, and use SCM_STREAM to get the stdio FILE *.
231 Also, use prototyped definitions, and get rid of the extra
233 (scm_fptob, scm_pipob): We don't need casts here any more.
234 * strports.c (prinstpt): Use prototype declarations.
235 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
236 and use SCM_STREAM to get the string info. Also, use prototyped
237 definitions, and get rid of the extra declarations.
238 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
241 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
242 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
244 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
245 scm_fgets, for consistency.
246 (scm_fptop, scm_pipob): References updated.
248 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
250 Include the source location in error messages for scripts.
251 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
252 stack is still there when we catch the error.
253 * throw.c (handler_message): If we are handling an error with a
254 message, then put together the proper arguments and call
255 scm_display_error, instead of scm_display_error_message. That
256 displays source location, if it can find it.
258 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
260 * gc.c (scm_unprotect_object): Change this so that calls to
261 scm_protect_object and scm_unprotect_object nest properly.
262 (scm_protect_object): Doc fixes.
264 * strings.c (scm_string_set_x): Require the argument to be a
265 writable string, not a substring or a symbol.
266 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
267 (Thanks to John Redford and Charbel Jacquin.)
269 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
271 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
273 * eval.c (safe_setjmp): Remove this misunderstanding.
274 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
277 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
279 * libguile.h: Mark these as C declarations, for compilation by C++
282 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
283 __cplusplus clause. I seriously doubt this ever worked the way
284 the author seems to have intended.
286 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
288 Utterly needless cleanups to hopelessly messy code.
289 * ports.c: Doc fixes.
290 (scm_fflush): Moved to ...
291 * genio.c (scm_fflush): ... here, amongst all the other port
292 method invocation functions.
293 * genio.h, ports.h: The prototype moves too.
295 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
297 * backtrace.c (display_error_body): The current frame does not
298 always have a parent frame; consider a function called directly
299 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
302 * alloca.c (alloca): Undo yesterday's changes, and simply call
303 malloc directly for storage, and abort if we don't get what we
304 want. The situation is much simpler --- just call malloc. Emacs
305 has bizarre/evil requirements (signal handlers might malloc unless
306 you set this global flag, so you have to set the flag around all
307 calls to malloc) which we are certainly not going to conform to,
308 so we can do the simple and obvious thing.
310 * coop.c (coop_condition_variable_wait): Make this function
311 static. It's only useful internally --- you should never just
312 wait on a condition variable.
313 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
315 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
317 * unif.c (scm_array_set_x): Accept any kind of number as an
318 element for a uniform vector of doubles. This is more consistent
319 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
321 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
322 works; I can't conveniently test it myself. (Thanks to Dvid
323 Tillman for the bug report.)
327 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
328 from here, not from scm_compile_shell_switches (which is a pretty
329 dumb place to do it).
330 (scm_load_startup_files): New function.
331 (scm_ice_9_already_loaded): Variable moved to here from script.c.
332 * script.c (scm_compile_shell_switches): Don't load the startup
334 (scm_ice_9_already_loaded): Variable moved.
335 * init.c (scm_load_startup_files): Prototype for new function.
336 * gh_init.c (gh_enter): Doc fix.
338 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
340 Some anti-warning changes from Greg Harvey.
341 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
342 warnings when it doesn't understand our NORETURN declarations in
344 * posix.c (scm_mknod): Similar.
346 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
348 * posix.c (scm_getpwuid): If we can't find an entry, return our
349 own message, instead of using scm_syserror --- the getpwMUMBLE
350 functions don't set `errno' to anything interesting.
352 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
354 Get rid of warnings from the cooperative threading system.
355 * threads.h (scm_single_thread_p, scm_yield,
356 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
357 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
358 scm_wait_condition_variable, scm_signal_condition_variable): Add
359 prototypes for these Scheme-visible functions.
360 * coop-defs.h (coop_next_runnable_thread,
361 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
362 Prototypes for these here, even though they're from iselect.c.
363 (coop_condition_variable_wait, coop_join): Add prototypes.
364 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
365 scm_threads_free_condvar): Make these smob functions static.
366 * coop-threads.h (coop_init): Give this a real prototype.
367 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
368 (coop_next_runnable_thread): No need to provide prototype; it's in
371 * scmconfig.h.in: .detarenegeR
373 * iselect.c, threads.c: Doc fixes.
375 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
377 * Makefile.in: Regenerated with a patched automake, to get
378 dependency generation right when using EGCS.
380 * inet_aton.c (inet_aton): Add prototype, to remove compiler
381 warning. (Thanks to Robert Pluim.)
383 * inet_aton.c (inet_aton): Reassure the compiler that the
384 arguments to the <ctype.h> macros are all unsigned characters, not
387 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
389 Getting rid of more warnings...
390 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
391 today's change to ../configure.in.
392 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
393 * scmconfig.h.in: Regenertaded.de.,.__
394 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
395 (scm_localtime, scm_mktime): Use a const char * to manipulate the
398 * readline.c: Doc fix.
399 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
400 * readline.h (scm_filename_completion_function): Add prototype.
401 (scm_init_readline): Make this into a prototype.
403 * readline.c (scm_filename_completion_function): Use SCM_PROC to
404 declare this, instead of calling scm_make_subr manually.
406 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
408 * readline.h (scm_init_readline): Add prototype for this.
409 (scm_init_readline): Make this a real prototype.
411 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
413 Warning fixes from Maciej Stachowiak:
414 * backtrace.h (scm_display_application, scm_backtrace): Add
416 * debug.c (scm_m_start_stack): Make this function static.
417 * fluids.h (scm_fluid_p): Add prototype.
418 * procprop.c (scm_i_procedure_arity): Make this function static.
419 * regex-posix.c (scm_regexp_error_msg): Make this function static.
420 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
421 * root.h (scm_dynamic_root): Add external prototype.
422 * scmsigs.h (scm_usleep): Add external prototype.
423 * script.h (scm_init_script): Use prototype, not K&R decl.
424 * stacks.h (scm_stack_id): Add external prototype.
425 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
427 1998-09-30 Mark Galassi <rosalia@cygnus.com>
429 * gh.h: took out the definitions of vset and vref, since they are
430 replaced by the proper vector routines that correspond to the R4RS
433 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
435 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
436 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
437 third argument, a C expression that should result in a SCM value,
438 which is used to initialize the variable. Reimplemented
439 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
442 * version.h (scm_libguile_config_stamp): Add prototype.
443 (From Maciej Stachowiak.)
445 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
447 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
448 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
450 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
452 * print.c (scm_iprin1): Rather than having one i, and using it in
453 several places, declare a fresh i local to each block where it is
454 used, and give it a signedness appropriate to its use in each case.
457 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
460 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
461 signed/unsigned clashes.
463 * posix.h (scm_tmpnam): Added prototype.
465 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
466 scm_make_subclass_object): Add external prototypes.
468 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
469 comparison is okay here.
471 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
473 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
474 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
476 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
479 * load.c (swap_port): Make this function static.
481 * load.c (scm_search_path): Make max_path_len and max_ext_len
482 unsigned, since they're compared against string sizes.
484 * load.c (init_build_info): Make i unsigned.
486 * ioext.h (scm_read_line): Add prototype.
488 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
489 scm_hash_fn_remove_x): Make hash bucket index local variable k
490 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
491 accurately as possible.
493 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
494 comparisons, and range checking to make sure those casts are
497 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
498 signed/unsigned comparisons.
500 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
501 avoid signed/unsigned comparisons.
502 * smob.h (scm_numsmob): Change extern declaration to match.
504 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
505 avoid signed/unsigned comparisons.
506 * ports.h (scm_numptob): Change extern declaration to match.
507 (scm_current_load_port, scm_set_port_line_x,
508 scm_set_port_column_x): New prototypes.
510 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
511 test code, and it causes warnings.
513 * gh.h (gh_int2scmb, gh_uniform_vector_length,
514 gh_uniform_vector_ref): Added prototypes.
516 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
517 debugging support unconditionally. That's backtrace.c, stack.c,
518 debug.c, and srcprop.c.
519 (EXTRA_libguile_la_SOURCES): Omit those from here.
520 * Makefile.in: Regenerated.
522 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
524 * options.c (scm_options): Bugfix: Allow empty list of options!
526 * debug.c, debug.h (scm_single_step): Removed.
527 (scm_with_traps): New procedure. This procedure could easily be
528 written in Scheme but needs to be highly optimized.
530 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
532 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
533 Check SCM_TRAPS_P before trapping.
535 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
537 Changes to avoid signed/unsigned comparison warnings.
538 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
539 (scm_gc_sweep): Make n and j local to the blocks they're used in,
540 so they can have appropriate types for each application. Make i
541 signed. Use initializers in some spots. I'll probably pay for
543 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
544 (scm_must_realloc): Make nm unsigned.
545 (init_heap_seg): Make new_seg_index and n_new_objects signed.
546 (scm_init_storage): Use prototype-style definition, and make the
548 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
549 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
551 * filesys.c (scm_readlink): Make local vars rv and size ints, to
552 avoid signed/unsigned comparison warnings, and because the return
553 value of readlink may be -1. Don't bother casting the third
554 argument to readlink.
556 * filesys.c (scm_dirname, scm_basename): Move these to their own
557 page, at the end of the file.
558 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
560 * eval.h (scm_eval_options_interface): Add external prototype for this.
561 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
563 * eval.c (scm_lookupcar1): Make this static.
565 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
566 Make these prototype declarations, not K&R-style.
568 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
569 unsigned comparison warning.
571 * appinit.c: File removed. It had a single function in it, empty,
572 whose reason for existence is explained in no documentation or
573 comment. I think it's there as a default for some Tcl-style
574 initialization, but Tcl abandoned that approach a while ago.
575 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
576 (BUILT_SOURCES): Remove appinit.x.
577 * Makefile.in: Regenerated.
579 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
581 * Makefile.in: Regenerated using the last public version of
582 automake, not the hacked Cygnus version.
584 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
586 Remove Totoro kludge.
587 * Makefile.in, scmconfig.h.in: Regenerated.
588 * init.c, readline.c: Don't check if TOTORO is #defined.
590 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
592 * Makefile.am: Adjust for new thread configuration system.
593 (INCLUDES): Include the value of THREAD_CPPFLAGS.
594 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
596 (THREAD_LIBS): Definition deleted; automake will generate such
597 things automatically.
598 * Makefile.in: Regenerated.
600 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
602 Simplify smob and port marking; set the mark bit in the generic
603 marking code, and make marker routines only responsible for
604 turning up outgoing pointers.
605 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
606 before calling the marking function. Don't call the marking
607 function if it's zero.
608 * markers.c (scm_mark0): Just return #f. This function isn't
609 necessary at all now, but it's harmless to call it. We'll leave
610 it in so other folks' code doesn't croak at link time.
611 (scm_markcdr): Don't call SCM_SETGC8MARK.
612 * async.c (mark_async): Don't call SCM_SETGC8MARK.
613 * dynl.c (mark_dynl_obj): Same.
614 * root.c (mark_root): Same.
615 * srcprop.c (marksrcprops): Same.
616 * unif.c (markra): Same.
617 * variable.c (scm_markvar): Same.
618 * ports.c (scm_markstream): Same.
619 (void_port_ptob): Specify zero for our marking function.
620 * debug.c (debugobjsmob): Same.
621 * dynwind.c (guardsmob): Same.
622 * filesys.c (dir_smob): Same.
623 * fluids.c (fluid_smob): Same.
624 * fports.c (scm_fptob, scm_pipob): Same.
625 * mallocs.c (mallocsmob): Same.
626 * regex-posix.c (regex_t_smob): Same.
627 * smob.c (freecell, flob, bigob): Same.
628 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
629 * throw.c (jbsmob, lazy_catch_funs): Same.
631 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
633 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
634 scm_copy_tree on code in order not to let memoized code to leak
635 out. Thus, scm_copy_tree needs to copy vectors as well since
636 quasiquote can introduce evaluated code also inside vector
639 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
641 * eval.c (scm_copy_tree): Removed ability to copy vectors.
643 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
644 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
647 * unif.c: Say that ivect and uvect are of type signed and unsigned
648 long instead of int in commentary so that it correctly describes
651 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
653 * stime.c: Removed declaration of strptime. (It should be
654 declared by the system headers. If it turns out that some systems
655 don't, we'll handle that then.) (Thanks to Greg Troxel.)
657 * stime.h: Renamed TIMEH --> STIMEH
659 * backtrace.c (scm_display_error, scm_display_backtrace): In order
660 to increase portability, don't use structure assignment.
661 (Thanks to Nicolas Neuss.)
663 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
665 (finalize_fd_sets): Added empty statement after last case label.
666 (Thanks to Nicolas Neuss.)
668 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
671 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
673 * init.c, readline.c: OK, I won't have these readline.x bug
674 reports anymore. We've had them since April. The current reason
675 is a completely unintelligible failure of totoro.red-bean.com to
676 do the test for rl_getc_function in libreadline correctly. This
677 kludge overrides the test if we're on totoro so that the snapshot
678 generation process can work.
680 * readline.c: Define a strdup replacement if not existent on system.
682 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
684 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
685 This change makes scm_make_vector R5RS compatible. We cannot keep
686 the third argument since people want to be able to deduce the form
687 of the C function call only by looking at R5RS. (At the same time
688 we have removed some unnecessary complexity!)
690 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
691 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
692 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
693 argument in call to scm_make_vector.
695 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
697 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
698 This macro is useful in applications.
700 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
702 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
703 (scm_parse_path, scm_search_path): New Scheme level procedures.
705 * load.h (scm_internal_parse_path, scm_parse_path,
706 scm_search_path): Declared.
708 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
710 * filesys.c (dirname, basename): New procedures.
712 * init.c (scm_boot_guile_1): Removed condition around
715 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
716 new data type (guards) for representation of C level guards and
717 data on the wind chain.
718 (scm_internal_dynamic_wind): New function.
720 * dynwind.h: Declare scm_internal_dynamic_wind.
722 * root.h (scm_root_state): Added scm_cur_loadp.
724 * root.c (mark_root): Added comment about cur_loadp.
726 * load.c: #include "dynwind.h";
727 (scm_primitive_load): Use scm_inner_dynamic_wind to update
730 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
732 * ports.c (current-load-port): New procedure.
734 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
736 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
737 not a tty, return #f.
739 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
740 to Julian Satchell and Roland Kaufmann.)
742 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
743 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
745 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
747 * debug.h, debug.c (scm_start_stack): New function. Implements
748 the guts of old scm_m_start_stack.
750 * debug.c (scm_m_start_stack): Use scm_start_stack.
752 * init.c (scm_start_stack, scm_restart_stack): Renamed to
753 start_stack and restart_stack. (These have static scope.)
755 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
757 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
758 readline functions to come in release 2.3. (Thanks to Chet
760 (handle_errors): Use the above functions.
762 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
764 * readline.c: Improvements for readline support: Handle errors
765 better; Implement before-read-hook.
767 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
769 * init.c (scm_boot_guile_1), readline.c: Test for
770 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
771 assure that we have version >= 2.1.)
773 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
775 * readline.c (scm_readline): Defer interrupts while we're calling
778 * readline.c (scm_add_history): Bugfix: Do strdup before giving
779 away the string to add_history.
780 (completion_function): Do completion for readline. (Thanks to
782 (scm_filename_completion_function): New procedure: Filename
784 (current_input_getc): New function. Use this one instead of
785 standard getc from readline.
787 * throw.c, throw.h (scm_handle_by_throw): New function: This
788 handler throws errors to next handler on the dynwind chain.
790 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
792 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
795 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
797 * procprop.c (scm_i_procedure_arity): New function. Returns arity
799 (scm_procedure_properties): Modified to return arity together with
801 (scm_procedure_property): Added the read-only property `arity'.
802 (scm_set_procedure_property_x): It is an error to set the `arity'
805 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
806 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
808 * procprop.h (scm_sym_arity): New symbol.
810 * objects.c (scm_set_object_procedure_x): New procedure: Use this
811 to set the dispatch procedure of an operator or entity object.
813 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
814 Made procedure slots read-only.
816 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
817 scm_tcs_cons_gloc case in zero args switch; Fixed args
818 construction for operators in scm_tcs_cons_gloc case in two args
821 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
823 * fluids.c: Removed use of assert.h (in order to avoid
826 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
828 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
830 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
831 change makes the evaluator safer at the cost of evaluation speed.
832 It handles the case when the user has added a non-immediate
833 improper end of the application form, e.g., `(+ 0 . x)'.
834 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
835 minimize the extra cost as much as possible. The new code is
836 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
837 problem with structs planted directly in the code (e.g. by a
838 macro). This no longer causes segmentation fault. (Thanks to
841 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
842 arg `proc' in order to be able to throw errors; New argument
845 * Removed extra #include "debug.h"
847 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
849 * scmsigs.c: Declare usleep as returning void on some systems.
850 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
853 * coop.c (usleep): Return void on some systems.
855 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
857 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
859 * coop.c: Changed return type of usleep to int.
861 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
862 isn't found in the OS.
864 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
865 isn't enabled. (Thought that I had made this change ages ago...)
867 * iselect.c: Declare bzero if not defined by OS.
869 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
871 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
872 condition. (Thanks to John Tobey.)
874 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
875 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
878 * __scm.h: Start the long-term project of moving to POSIX threads.
879 Phase 1: Classification of all critical sections.
880 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
881 for A sections. (See comments in __scm.h for details.)
883 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
884 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
886 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
888 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
889 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
890 (libpath.h, versiondat.h): Replaced dependency on Makefile with
891 dependencies on $(srcdir)/Makefile.in
892 $(top_builddir)/config.status in order to avoid circularity.
894 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
895 from argc if argc was 0 initially.
897 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
898 in generation of libpath.h.
900 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
902 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
903 libguile from 2 to 3.
905 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
907 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
909 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
911 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
912 scm_set_port_column_x, scm_port_filename,
913 scm_set_port_filename_x): Removed optional arguments. Added
914 proper argument checking.
916 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
917 stack size in machine words.
919 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
920 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
921 to Ole Myren Röhne.)
923 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
925 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
926 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
928 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
931 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
932 procedure apply: Copy argument lists before pushing them unto the
933 environment so that the environment won't get mutated due to
934 manipulation of procedure arguments. This should perhaps be
935 regarded as a temporary solution until someone finds a more
936 efficient one. (Thanks to Maciej Stachowiak.)
938 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
940 * script.c (scm_compile_shell_switches): Use "guile" as default
941 zero arg if argc is NULL.
943 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
945 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
946 is zero. (Thanks to Dirk Herrmann.)
948 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
950 * ports.c (scm_add_to_port_table): First line is now line 0
951 (was 1). (Interface changed according to suggestion by Per
954 * backtrace.c (display_header): Add 1 to line and column numbers
955 when presenting them to the user.
957 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
958 from debug.c --> eval.c
960 * eval.h, eval.c (scm_eval_options_interface): New options
962 (SCM_EVAL_STACK): New option: Size of newly created stacks,
963 i.e. stacks for new threads.
965 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
967 * eval.c (unsafe_setjmp): Removed with #if 0.
969 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
972 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
973 to avoid compiler warnings.
975 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
977 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
979 * throw.c (handler_message): Print message on current error port
980 instead of default error port. (Thanks to Maciej Stachowiak.)
982 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
984 * ports.c (scm_add_to_port_table): allocate in units of
985 struct scm_port_table *, not struct scm_port_table.
986 * posix.c (scm_close_pipe): remove the port from the port table
988 Thanks to Rob Engle for both fixes.
990 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
992 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
993 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
995 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
997 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
999 * backtrace.c (display_error_body, display_backtrace_body),
1000 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
1001 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
1002 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
1003 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
1006 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
1007 don't receive the jmpbuf arg anylonger.
1008 (scm_catch): Don't accept a #f tag.
1009 (scm_throw): Check that key is a symbol.
1010 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
1012 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
1014 * async.c (async_pending): Removed declaration.
1016 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1018 * dynwind.c (scm_wind_chain): New debug function.
1020 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
1021 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
1022 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
1023 extra layer of functions around the body and handler of a thread.
1024 This extra layer makes sure that the handler is called in the
1025 dynamic context of the surround (= empty dynwind list), but under
1026 the *dynamic root* of the body. We can not use the dynamic root
1027 of the surround since that root belongs to another thread => stack
1028 is not handled correctly. It may seem ugly to use this extra
1029 layer, but the extra cost in terms of execution time is really
1030 negligible compared to the total amount of time required to create
1031 a thread, and it would reduce maintainability to duplicate the
1032 crucial and complicated steps performed by cwdr.
1034 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
1035 (SCM_ALLOW_INTS): Added thread switching code before interrupts
1036 get re-enabled. The important effect of this is that interrupts
1037 are blocked during thread switching so that thread data structures
1038 don't risk getting messed up by an unfortunate signal.
1039 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
1040 seems to do more aggressive optimization which actually move
1041 instructions around in these macros in a fatal way. Therefore:
1042 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
1043 just superstitious...)
1044 (SCM_TICK): Maybe do a context switch and take care of asyncs.
1045 This macro should be used instead of SCM_ASYNC_TICK since the
1046 latter doesn't do context switches any more.
1048 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
1049 instead of SCM_ASYNC_TICK.
1051 * coop.c, iselect.c: Since thread switches are now performed with
1052 interrupts masked, we can't use the old mechanism of delivering
1053 signals immediately when they arrive. Signals must instead be
1054 delivered when the asyncs run *after* the end of the critical
1055 section in scm_internal_select. But this also means after context
1056 switch so that the signal will be delivered to a different thread.
1057 To avoid this, I have changed the protocol of
1058 coop_wait_for_runnable_thread and friends so that they are allowed
1059 to return the original thread. So, if a signal arrives during
1060 scm_internal_select, we won't any longer be forced do a context
1061 switch, but can remain in the same thread and deliver the signal
1064 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
1065 scm_asyncs_pending and made it global.
1067 * iselect.c: Small fixes.
1069 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
1070 coop_condition_variable_init, coop_condition_variable_wait,
1071 coop_condition_variable_signal): Changed return type from `void'
1072 to `int'. This is to adhere closer to the pthreads interface.
1073 This, in turn, is part of an attempt to provide C versions of the
1074 mutex and condition variable primitives which can be part of a
1075 frontend to COOP or pthreads.
1077 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
1078 coop_condition_variable_destroy): New functions.
1080 * coop-threads.c (scm_wait_condition_variable): Use
1081 coop_condition_variable_wait_mutex.
1083 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
1084 Definitions moved to coop-defs.h.
1086 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
1087 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
1088 scm_cond_destroy): New C interface to mutecis and cond vars.
1090 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1092 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
1094 * iselect.c: Now several threads can wait on the same file
1095 descriptor. The behaviour is compatible with OS select: All
1096 threads waiting for the fd return with the same status.
1098 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1100 * coop-threads.c, threads.h (scm_spawn_thread): New function.
1101 Can spawn a thread from application C code.
1103 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1105 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
1106 gh_doubles2scm): New functions.
1108 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
1110 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
1111 commented-out version of gh_eval_str()
1113 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
1115 * socket.c (scm_bind): free soka after use.
1117 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
1119 * stime.c (tzvar): new variable.
1120 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
1121 avoid memory leaks when allocating.
1123 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
1125 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
1128 * gc.c, tags.h: Doc fixes.
1130 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1132 * eval.c (macro-eval!): Removed. This function was a design bug.
1133 It allowed memoized code to leak out to the scheme level. Most
1134 things that you could do with `macro-eval!' can be done with
1137 1997-12-20 Tim Pierce <twp@skepsis.com>
1139 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
1140 scm_fgets now depends on ftell(3) to know how many bytes were
1143 1997-12-15 Tim Pierce <twp@skepsis.com>
1145 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
1146 dealing with strings.
1148 1997-12-13 Tim Pierce <twp@skepsis.com>
1150 Make %read-line more suitable for implementing read-line efficiently.
1151 * ioext.c (scm_read_line): Strip the terminating newline from a
1152 string, and return a cons of the string and its terminator.
1154 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
1155 of the string that is read is stored in this memory location.
1156 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
1157 * genio.c, genio.h (scm_do_read_line): Update caller.
1158 * ports.h (scm_ptobfuns): Update typedef.
1159 * fports.c (scm_fptob, scm_pipob): Update struct.
1161 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1163 * filesys.c (set_element): Return file descriptor.
1164 (fill_select_type): Return the highest file descriptor.
1165 (scm_select): Tell select about the highest file descriptor. On
1166 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
1167 Therefore the extra overhead for calculating the maximum fd seems
1168 to be more than compensated. Is this correct? In any case,
1169 scm_internal_select will be much faster with this info.
1170 (scm_select, fill_select_type, set_element): Don't accept any kind
1171 of object in the file descriptor list or vector.
1173 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1175 * iselect.c (finalize_fd_sets): Bugfix.
1177 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1179 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1180 when using scm_internal_select (since we might switch to another
1183 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1185 * simpos.c (scm_system): always define: use sysmissing if not
1186 available. Check for HAVE_SYSTEM instead of _Windows (does
1187 Windows lack system or does it have an unusable one?).
1188 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1189 Let the argument be optional: if not supplied, call system(NULL).
1191 * ports.c (scm_close_port): relax the type check from OPPORTP to
1192 PORTP; closing a closed port is allowed.
1194 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1196 * fports.c (scm_fgets): Return if the last char in a chunk is
1197 newline. When fgets returns a string whose length is `size-1', it
1198 is ambiguous whether a whole line was retrieved, so we must check
1199 explicitly whether a line terminator is present.
1201 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1203 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
1204 before taking the CDR. (Thanks to Harald Meland.)
1206 * filesys.c (scm_stat): Slightly optimized.
1208 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
1210 * ports.c (scm_close_port): Make sure the port is open before
1213 * guile-snarf.in: Pass args through to gcc in a way that preserves
1214 whitespace boundaries. (Thanks to Greg Badros.)
1216 1997-12-02 Tim Pierce <twp@skepsis.com>
1218 * stacks.c (scm_frame_procedure): Reverse the logic in the return
1219 statement. (Thanks to Doug Evans for pointing this out.)
1221 1997-12-01 Tim Pierce <twp@skepsis.com>
1223 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
1225 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
1227 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
1228 errno macro expansion of this field name. (errno is a C
1229 preprocessor macro on some systems.)
1231 1997-11-29 Tim Pierce <twp@skepsis.com>
1233 * iselect.c: Doc fix.
1235 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
1237 * init.c (scm_start_stack): Removed initialization of
1238 scm_the_last_stack_var.
1240 * backtrace.h: Declare scm_the_last_stack_var.
1242 * backtrace.c: Define scm_the_last_stack_var.
1244 * root.c (mark_root): Don't mark the_last_stack_var.
1246 * root.h (scm_root_state): Removed the_last_stack_var.
1248 * throw.c: Added #include "fluids.h"
1249 (ss_handler): `the-last-stack' is now a fluid.
1251 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
1252 --> the_last_stack_fluid.
1254 * backtrace.c: Added #include "fluids.h"
1255 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
1256 (scm_backtrace): `the-last-stack' is now a fluid.
1258 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
1259 after scm_init_fluids.
1261 1997-11-28 Tim Pierce <twp@skepsis.com>
1263 * iselect.c: #ifdef USE_THREADS around thread-related includes.
1265 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
1266 DLSYM_ADDS_USCORE to decide whether to add an underscore.
1268 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1270 * iselect.c (coop_next_runnable_thread,
1271 coop_wait_for_runnable_thread): Disable interrupts so that no
1272 async is executed before a potential error_revive.
1273 (scm_internal_select): Disable interrupts during the parts of the
1274 code which manipulate the sleep queue and the file descriptors.
1276 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1278 * Makefile.am: Added iselect.c and iselect.h.
1280 * coop.c (coop_qinit): Initialize fields used by
1281 scm_internal_select.
1282 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1283 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1284 replacement in iselect.c.
1285 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1286 coop_join): If GUILE_ISELECT enabled, use
1287 coop_wait_for_runnable_thread instead of
1288 coop_next_runnable_thread.
1289 (usleep, sleep): New replacements for system functions if
1290 GUILE_ISELECT is enabled.
1292 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1294 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1296 * filesys.c: Added #include "iselect.h". Moved FD-macros to
1297 iselect.h. Implement Scheme level `select' using
1298 scm_internal_select. (See NEWS.)
1300 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1302 * init.c: Call scm_init_iselect.
1304 * iselect.h, iselect.c: New files. Implements
1305 scm_internal_select. (See NEWS.)
1307 1997-11-27 Tim Pierce <twp@skepsis.com>
1309 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1310 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1311 and scm_must_free, since ultimately the string returned will be copied
1312 by scm_makfrom0str anyway. Also, read any characters that may have
1313 been pushed onto the port with scm_ungetc.
1314 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1315 * ioext.c (scm_read_line): Free string after Guilifying it.
1316 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
1318 1997-11-26 Anthony Green <green@hoser.cygnus.com>
1320 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
1322 * gh.h: Safely wrap prototypes for c++ usage.
1324 1997-11-25 Mark Galassi <rosalia@cygnus.com>
1326 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
1327 gh_repl (argc, argv).
1329 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1331 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1332 and to invoke scm_shell().
1333 (gh_launch_pad): took out the loading of boot-9.scm from here,
1334 since it is probably best to let the user control that. In fact,
1335 gh_repl() now invokes scm_shell() which does that.
1337 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1339 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
1342 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
1344 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
1345 yesterday's underscore patch. (Thanks to Marius Vollmer for
1348 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
1350 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
1351 DLSYM_ADDS_USCORE is not defined.
1353 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
1355 * gh_data.c (gh_uniform_vector_length):
1356 (gh_uniform_vector_ref): started implementing the uniform types in
1359 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
1361 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1362 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1364 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1366 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1367 configure.in was changed).
1369 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
1371 * Makefile.am (modinclude_HEADERS): Include readline.h here.

1374 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1376 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1377 OPORT is an `open' port, not an output port.
1379 * filesys.c (scm_close, set_element, get_element, scm_chown,
1380 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
1381 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
1382 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
1383 scm_close_port, scm_port_line, scm_set_port_line_x,
1384 scm_port_column, scm_set_port_column_x, scm_port_filename,
1385 scm_set_port_filename_x, scm_port_mode,
1386 scm_close_all_ports_except, scm_set_current_output_port,
1387 scm_set_current_error_port): Likewise
1388 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1389 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
1391 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
1392 * backtrace.c (display_backtrace_body): Likewise
1393 * fports (scm_setvbuf): Likewise
1394 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
1395 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
1396 scm_getpeername, scm_send, scm_sendto): Likewise
1397 * unif.c (scm_uniform_array_write): Likewise
1399 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
1401 Minor problems with substring-related tag changes.
1402 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1403 exactly what we want to leave in to detect substrings.
1404 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1405 * tags.h: Fix diagrams and comments describing the S tag bit;
1406 remove vestigial remarks about the D tag bit.
1407 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
1408 * strings.c: Formatting tweaks.
1410 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1411 variable first; then SCHEME_LOAD_PATH, with a warning message.
1412 (scm_parse_path): New function.
1413 * script.c: Doc fixes.
1415 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1417 Readline support, from Daniel Risacher.
1418 * readline.c, readline.h: New files.

1421 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1422 * Makefile.in: Regenerated.
1423 * scmconfig.h.in: Regenerated, after change to ../configure.
1425 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1427 * gh.h: gh_vector_set -> gh_vector_set_x
1429 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1431 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1432 with the ! -> _x mapping when going from Scheme to C.
1434 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1436 * gh.h (gh_reverse):
1444 (gh_assoc): added these gh_ functions implemented as macros.

1447 (gh_string_equal_p): added these two missing predicates.
1449 * gh_list.c (gh_append):
1454 (gh_set_cdr_x): added these routines as I go through and try to
1455 complete the picture R4RS functions that should be mirrored in the
1458 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1460 * tags.h (scm_tc7_substring): Changed the comment and code to
1461 conform with the changes below. Folks! We have suddenly two new
1462 free tc7 codes!!! Jummy, jummy!
1464 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
1466 * Makefile.in: Rebuilt.
1467 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
1469 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
1470 * unif.c (scm_vector_set_length_x): Don't handle multibyte
1472 * tag.c (scm_utag_mb_string, scm_utag_mb_substring): Removed.

1484 * eq.c (scm_equal_p): Use SCM_TYP7S, not SCM_TYP7SD.
1485 * tags.h (SCM_TYP7SD): Removed.
1486 (SCM_TYP7D): Removed.
1487 (scm_tc7_mb_string): Removed.
1488 (scm_tc7_mb_substring): Removed.

1493 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
1495 Don't include "mbstrings.h".
1496 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
1497 (SCM_SYMBOL_SLOTS): Define as 4.
1498 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.

1519 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
1520 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
1522 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1524 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1526 * gh_test_c.c (c_vector_test): some improvements on the vector
1529 * gh.h (gh_vector): this used to exist but do the wrong thing.
1530 Now it (almost) does the right thing, though it takes a list
1531 instead of the individual arguments. I need to see how it could
1533 (gh_list_to_vector): added this function as a macro. Corresponds
1534 to Scheme's (list->vector ...).
1535 (gh_vector_to_list): added this function as a macro. Corresponds
1536 to Scheme's (vector->list ...).
1538 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1539 gh_vector_ref, so that it resembles the Scheme routines more.
1540 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1541 resembles the Scheme routines more.
1542 (gh_make_vector): this used to be (stupidly) called gh_vector().
1543 This is the right name, since it does the same thing as the Scheme
1544 (make-vector ...) procedure.
1546 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1548 * ports.h: #include "libguile/print.h"
1550 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
1551 Some indentation fixes.
1553 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
1554 longer a user field; New field: class_flags.
1556 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
1558 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
1560 * gh_data.c (gh_bool2scm): new function which replaces
1561 gh_int2scmb(), which is now tagged as obsolete.
1563 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1565 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1566 macros should by convention not test for NIMPness.)
1567 (SCM_COERCE_OPORT): Adjust indentation.
1569 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1570 SCM_NIMP test before SCM_PRINT_STATE_P.
1572 * struct.c, struct.h, gc.c: Renamed:
1573 scm_struct_i_layout --> scm_vtable_index_layout
1574 scm_struct_i_vcell --> scm_vtable_index_vcell
1575 scm_struct_i_vtable --> scm_vtable_index_vtable
1576 scm_struct_i_printer --> scm_vtable_index_printer
1577 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1579 * struct.c (scm_print_struct): Use new printer slot; Default
1580 printing: Also output hex code of vtable so that type identity
1581 will be indicated as well.
1582 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1583 Removed struct_printer_var; Removed struct-vtable-offset;
1584 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1585 vtable-offset-user): New constants.
1587 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
1588 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
1589 If this slot contains a procedure, use that to print structures of
1590 the type represented by this vtable.
1592 * print.c (scm_iprin1): Don't print arguments of macro
1593 transformers. (They are always: exp env.); Bugfix: Unmemoize
1594 transformer source with correct environment.
1596 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1598 Streamlining of call-with-dynamic-root:
1600 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
1601 there is now only one catch.
1602 (cwdr_outer_body): Removed.
1603 (cwdr_handler): New function.
1604 (scm_internal_cwdr): New function to perform the function of cwdr
1605 but take args that are more useful to C code. Also, the handler
1606 is now invoked *outside* of the new dynamic root, like the docs
1607 say. We no longer have to catch absolutely all errors, the caller
1608 is responsible for using a handler that does not throw, if he
1610 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1611 * root.h (scm_internal_cwdr): New prototype.
1613 Even more but risky streamlining:
1615 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1616 allocation of the jumpbuf of a root continuation. The changes
1617 below are controlled by it. They are now deactivated.
1618 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1619 the JMPBUF of the scm_rootcont to NULL before returning.
1621 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1622 when they are non-NULL.
1623 (scm_gc_mark): Likewise, mark only when non-NULL.
1625 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1626 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1628 * gc.c (scm_done_malloc): New function.
1629 gc.h (scm_done_malloc): New prototype.
1631 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
1632 (struct scm_print_state) [revealed]: New field.
1633 (scm_print_state_vtable): Make visible to the outside world for
1634 type checking purposes.
1635 (scm_valid_oport_value_p): New prototype.
1637 * print.c (scm_valid_oport_value_p): New function to check whether
1638 a certain value is acceptable as a port argument.
1639 (scm_print_state_vtable): New variable.
1640 (scm_free_print_state): Set `revealed' field to false.
1641 (scm_iprin1): Call user supplied closure printer with
1642 scm_printer_apply. Print in the traditional way when there isn't
1643 one or when it returns #f.
1644 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1645 Accept a port/print-state pair in addition to just a port.
1646 (scm_prin1): Don't return the print_state to the pool when it has
1648 (scm_printer_apply): Set `revealed' field of print_state to true.
1649 (scm_init_print): Set scm_print_state_vtable.
1650 (print_state_fluid, print_state_fluid_num): Removed.
1652 * throw.h (scm_handle_by_proc_catching_all): New prototype
1653 throw.c (scm_handle_by_proc_catching_all): New function
1655 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1657 * Makefile.in: Regenerated with automake 1.2c.
1659 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1661 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1662 was looping endlessly.
1664 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1666 * strports.c (scm_eval_string): Don't close the port.
1668 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1669 former returns a nice normal integer. (Thanks to Daniel
1672 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1674 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1675 makefile variable as a build parameter called LIBS. The
1676 build-guile program will use this, for the time being.
1677 * Makefile.in: Regenerated.
1679 Thanks to Shiro Kawai:
1680 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1681 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1684 * Makefile.in: Regenerated with automake 1.2a.
1686 * script.c (scm_compile_shell_switches): If we hit the -c or --
1687 arguments, don't set the car of (command-line) to scm_usage_name,
1688 the prettified name of the guile executable; give it the full
1689 path, the way shells usually handle $0.
1691 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1693 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1694 Scheme-level name `array-map' and renamed `serial-array-map' to
1695 `serial-array-map!'.
1697 * backtrace.c: Introduced exception handlers which now enclose
1698 `display-error' and `display-backtrace' so that error reporting
1699 won't get into infinite loops if an error occurs during displaying
1700 of the error. This can very easily happen with user supplied
1701 print call-back routines.
1703 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1705 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1706 the names `serial-array-map' and `array-map' should be removed.)
1708 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1710 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1711 Added #include "objects.h"
1713 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1714 Add #include "feature.h".
1716 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1717 (modinclude_HEADERS): Added objects.h.
1719 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1720 This test is needed at many places in the code and should be
1721 abstracted. (Motivated by the need of this test in libguiletk.)
1723 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1724 (scm_eval_string), load.c (scm_primitive_load,
1725 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1726 Use SCM_EOF_OBJECT_P.
1728 * eval.c (scm_init_eval): Add feature `delay'.
1730 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1732 * scmhob.h: Removed.
1734 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1736 * list.h (SCM_LISTn): New macros. Make list creation in C code
1737 prettier. The idea comes from STk.
1739 * sequences.h, sequences.c, append.h, append.c: Removed. These
1740 files implemented non-R4RS operations which would encourage
1741 non-portable programming style and less easy-to-read code.
1743 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1746 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1747 sequences.h, #include append.h.
1749 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1752 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1754 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1756 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1758 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1760 * eval.c: Added #include "objects.h"
1762 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1765 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1766 adjacent smob numbers.
1768 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1770 * procprop.h: Added declaration of scm_i_inner_name.
1772 * gsubr.c: New global symbol scm_i_inner_name.
1774 * debug.c (scm_procedure_name): Try procedure property
1775 `inner-name' if `name' fails.
1777 * print.c (scm_iprin1): Use scm_macro_name.
1779 * eval.c (scm_m_define): Give names to macros as well; Only the
1780 first top-level definition gives a procedure/macro a name.
1781 Otherwise confusing names can turn up in backtraces.
1782 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1783 `name'; Give names to macros as well.
1785 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1786 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1789 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1791 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
1793 (prinmacro): Removed. The code has been moved/merged into print.c
1794 in order to decrease code redundancy. We want macros to print in
1795 a way equivalent to procedures, and it would be silly to duplicate
1796 the required code. (We don't want to maintain two places.)
1797 (macrosmob): Print field is now a NULL pointer.
1799 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1800 scm_macro_transformer): New prototypes.
1801 (scm_tc16_macro): Declared.
1803 * * print.c (scm_iprin1): Added code for printing of macros. Macros
1804 are now printed in a way equivalent to procedures.
1806 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1808 * procs.h (scm_closure_p): Added declaration.
1810 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1812 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
1813 Shouldn't pass "heap" as the subr name.
1815 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1817 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
1818 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
1819 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1820 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1821 SCM_BOOL_T. Any non-false value is true.
1823 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1825 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1826 scm_gensym): Added prototypes.
1828 * symbols.c (scm_gensym): New function. This will speed up
1829 certain types of applications (such as macro systems) which
1830 generate lots of symbols.
1832 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1834 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
1836 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
1838 * unif.c (scm_shap2ra): tighten the checking of the array dimension
1839 specifier, since (2) or (2 . 3) would cause SEGV.
1840 (scm_transpose_array): more argument checking fixes.
1842 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1844 * Makefile.in: Regenerated.
1846 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1848 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
1850 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1852 * error.c, error.h (scm_error_callback): Removed (see NEWS).
1854 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
1856 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
1857 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
1860 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
1861 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1862 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
1863 scm_array_p, scm_array_rank, scm_array_dimensions,
1864 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
1865 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
1866 scm_array_prototype): Added case scm_tc7_wvect.
1868 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
1870 * errno.h: prototype for scm_strerror.
1871 * error.c (scm_strerror): new procedure.
1873 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1875 * list.c (scm_list_append_x): Allow non-pair as last argument.
1876 This is consistent with the R4RS append and is probably the
1877 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1879 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1881 * stime.h: prototype for scm_times.
1882 * stime.c (scm_times): new procedure.
1883 * ioext.c (scm_fseek): if the first argument is a file descriptor
1885 (scm_ftell): if the first argument is a file descriptor call lseek
1887 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
1888 * filesys.c (scm_chmod): if the first argument is a file descriptor,
1890 (scm_chown): if the first argument is a port or file descriptor,
1892 (scm_truncate_file): new procedure.
1893 Add DEFER/ALLOW INTS to a few other procedures.
1894 (scm_fsync): new procedure.
1895 (scm_open_fdes): new procedure.
1896 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
1898 (scm_fcntl): the first argument can now be a file descriptor. The
1899 third argument is now optional.
1901 * posix.c (scm_execl, scm_execlp): make the filename argument
1902 compulsory, since omitting it causes SEGV.
1903 (scm_sync): return unspecified instead of #f.
1904 (scm_execle): new procedure.
1905 (environ_list_to_c): new procedure.
1906 (scm_environ): use environ_list_to_c. disable interrupts.
1907 (scm_convert_exec_args): take pos and subr arguments and
1908 improve error checking.
1910 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1912 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1913 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1914 argument to SCM_ASSERT. Furthermore, the name of the function
1915 should be passed as first argument when signalling
1916 SCM_WNA. (Thanks to Thomas Morgan)
1918 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1919 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1920 dispatches on the number of actual args has a default case
1921 reporting an internal error. This is a vestige from a version
1922 that mallocated a SCM vector to hold the arguments. In the
1923 current version this check is too late: if it ever happens we will
1924 have already overstepped the bounds of the array.
1926 Also, the patch [...] adds a check for too many actual arguments."
1928 mdj: Removed check for "internal programming error".
1930 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1932 * gh_io.c (gh_write): New function.
1934 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
1935 throw.c (scm_internal_stack_catch): New sibling to the other catch
1936 functions. Code moved from gh_eval.c.
1937 throw.h: Added header.
1938 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
1939 scm_internal_stack_catch.
1941 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1943 * ioext.h: fix up prototypes.
1944 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
1945 Scheme name is now dup->fdes.
1946 (scm_dup_to_fdes): make the second argument optional and
1947 fold in the functionality of scm_primitive_dup.
1948 (scm_primitive_dup): deleted.
1950 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1952 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
1953 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
1954 ultrix are defined. Use setvbuf instead of setbuf.
1955 (scm_setvbuf): new procedure.
1956 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
1957 (scm_setfileno): moved from ioext.c.
1958 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
1959 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
1961 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1963 * fluids.c (scm_fluid_p): New function.
1964 * fluids.h (scm_fluid_p): New prototype.
1966 Sat Jul 26 21:33:37 1997 Marius Vollmer <mvo@zagadka.ping.de>
1968 * print.c (scm_iprin1): Enter printed structures into the print
1969 state as nested data while they are printed.
1970 (print_state_fluid, print_state_fluid_num): New variables.
1971 (scm_init_print): Initialize them.
1972 (scm_iprin): If print_state_fluid carries a print_state, use that
1973 instead of creating a new one.
1974 (scm_printer_apply, apply_stub, struct apply_data): New
1975 definitions to help with calling printer functions written in
1977 * print.h (scm_printer_apply): New prototype.
1979 * struct.c (scm_print_struct): Use scm_printer_apply to call the
1980 user defined struct printer.
1982 * dynwind.c (scm_dowinds): Handle fluids on the wind list.
1983 * fluids.h (scm_internal_with_fluids, scm_with_fluids,
1984 scm_swap_fluids, scm_swap_fluids_reverse): New prototypes.
1985 * fluids.c (scm_internal_with_fluids, scm_with_fluids,
1986 scm_swap_fluids, scm_swap_fluids_reverse): New functions.
1988 Fri Jul 25 12:05:46 1997 Marius Vollmer <mvo@zagadka.ping.de>
1990 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
1991 SCM_ASSERT: arg comes before pos.
1993 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1995 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
1996 to a list of length zero correctly.

2012 Mon Jul 21 04:03:42 1997 Gary Houston <ghouston@actrix.gen.nz>
2014 * ioext.h: removed scm_duplicate_port prototype.
2016 * ioext.c (scm_primitive_dup2): return the new file descriptor
2017 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
2019 (scm_fdopen): bug fix: don't try to make port unbuffered until its
2020 stream has been set.
2021 (scm_duplicate_port): deleted, there's now an implementation in
2023 (scm_primitive_dup2): do nothing if newfd == oldfd.
2025 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
2027 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the

2031 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
2033 * fluids.c (next_fluid_num): don't do
2034 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
2036 * ports.h: prototypes too.
2037 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
2039 * fports.h: prototype too.
2040 * fports.c (scm_evict_ports): moved from ioext.c.
2042 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2044 * ports.c (scm_close_port): return a boolean instead of unspecified.
2045 throw an error if an error other than EBADF occurs.
2047 * filesys.h: scm_close prototype.
2048 * filesys.c (scm_close): new procedure, can close file descriptors
2049 and ports (scsh compatible).
2051 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
2054 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
2056 * fluids.c, fluid.h: New files.
2057 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
2058 (modinclude_HEADERS): Added "fluids.h"

2067 (scm_make_root): Call scm_copy_fluids to make fluid bindings
2068 unique for the new root when it has a parent.
2070 * smob.h: Include "libguile/print.h" to make scm_print_state
2073 * dynl.c (free_dynl_obj): New function to free the dynamic object
2074 data. (dynl_smob): Use it.
2075 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
2076 the dynamic object data below the linking of the object to avoid
2077 memory leak when the linking code throws an error. Now the code
2078 leaks a whole dynamically linked library when must_malloc throws,
2079 but that should be much less likely.
2081 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
2083 Changes to compile under gnu-win32, from Marcus Daniels:
2084 * stime.c (tzset): If tzset isn't provided, make it a NOP.
2085 (scm_localtime): Change SCM_EOF to SCM_EOL.
2086 (scm_mktime): Likewise.
2087 * socket.c: Don't include sys/un.h unless autoconf tells
2088 us Unix domain sockets are available.
2089 (scm_fill_sockaddr): Ignore Unix domain code.
2090 (scm_addr_vector): Likewise.
2091 (scm_init_addr_buffer): Likewise.
2092 (scm_socketpair): Don't include unless socketpair was
2093 found during autoconf.
2094 * simpos.c (SYSTNAME): Treat cygwin like Unix.
2095 * scmsigs.c (scm_pause): Don't include unless pause was found
2097 * posix.c (scm_getgroups): Don't include unless support function
2098 was found during autoconf (in this case, getgroups).
2099 (scm_setpwent): For setpwent.
2100 (scm_setegid): For setegid.
2101 * net_db.c (scm_inet_netof): Don't include unless support
2102 function was found during autoconf (in this case, inet_netof).
2103 (scm_lnaof): For inet_lnaof.
2104 (scm_inet_makeaddr): For inet_makeaddr.

2116 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
2117 scm_misc_error, not SCM_EOF.
2119 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
2120 arguments for formatting the error message, not SCM_BOOL_F. I
2121 think this is left over from the (eq? '() #f) days.
2123 * read.c (recsexpr): Give this a dummy definition if
2124 DEBUG_EXTENSIONS isn't #defined.
2126 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
2128 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

2138 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
2139 alloca.lo will be included in @LIBLOBJS@. Something better than
2140 this should be possible.
2141 * Makefile.in: Regenerated.
2143 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2145 * simpos.h: prototype for scm_primitive_exit.
2146 * simpos.c (scm_primitive_exit): new procedure, terminates the
2147 process without unwinding the stack.
2149 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
2151 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
2152 argument and logior its components together, so the user doesn't
2153 have to do this explicitly. Also, if regexp/basic is supplied, then
2154 turn off REG_EXTENDED.
2155 (scm_init_regex_posix): New regexp/basic symbol.
2156 (REG_BASIC): #define this if it is not already present.
2158 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2160 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.

2172 * Makefile.in: Regenerated.
2174 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
2175 flag; I don't think we support it.
2176 (scm_make_regexp): Make sure the user doesn't pass the
2179 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
2181 (scm_init_regex_posix): Define constants for the REG_mumble flags;
2182 name them according to the SCSH convention: regexp/mumble.
2184 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
2186 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
2188 * Makefile.am (libpath.h): Include the values of all the standard
2189 Makefile directory variables. Print a message, but don't print
2191 (versiondat.h): Print a message, but don't print all the commands.
2192 * load.c: #include "alist.h".
2193 (init_build_info): New function.
2194 (scm_init_load): Call it.
2195 * Makefile.in: Regenerated.
2197 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
2199 * root.c: Establish a reliable catch-all handler for the new root.
2200 After all the Scheme handler function might signal an error too,
2201 and we don't want to lose that.
2202 (cwdr_inner_body): Renamed from cwdr_body.
2203 (cwdr_outer_body): New function, to establish the user's handler,
2204 and pass control to cwdr_inner_body.
2205 (cwdr): Establish the reliable catch-all handler here, and pass
2206 control to cwdr_outer_body.
2207 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
2208 the user's handler through to cwdr_outer_body.
2209 * throw.c (scm_handle_by_message): Move guts into....
2210 (handler_message): New static function.
2211 (scm_handle_by_message_noexit): New function.
2212 * throw.h (scm_handle_by_message_noexit): New prototype.
2214 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
2215 across this. Only works on GCC. Otherwise, we hope for the best.
2216 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2217 the feeling that real thread systems will not need this...
2219 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2221 Try to detect when people are using one version of libguile and a
2222 different version of ice-9. People have been skewing things and
2223 sending in bug reports.
2224 * Makefile.am (versiondat.h): New file to generate.
2225 * version.c: #include "versiondat.h", to get version info.
2226 (scm_libguile_config_stamp): New function.

2229 * scmconfig.h.in, Makefile.in: Regenerated.
2230 * Makefile.in: Regenerated.
2232 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
2233 primitive definitions under their Scheme names.
2235 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2236 1:2. Helps avoid confusion between installed and uninstalled libs.
2238 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2241 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2242 backslash from definition; this should be used like: GDB_INTERFACE;
2244 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2246 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
2247 new port unbuffered until its stream has been set.
2249 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2251 * ports.h: new prototype.
2252 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
2254 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
2256 Make things compile neatly under Sun's C compiler.
2257 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
2258 * extchrs.c (xmbtowc): Make the second arg a normal char, not
2259 unsigned, because that's what the ANSI function takes.
2260 * extchrs.h (xmbtowc): Corresponding change to prototype.
2261 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2263 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2264 argument plain char *.
2265 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2267 * tag.c (scm_tag): Remove unreachable statement.
2268 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2269 top of the word, it should be unsigned.
2271 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2272 is defined, to avoid warnings; it's only used in the
2273 conflict-checking code. Which might go away anyway.
2274 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2275 conditionals; put the label definition in an #if too, to stifle
2278 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2279 ChangeLog-threads in the distribution.
2280 * Makefile.in: Regenerated.
2282 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2284 * guile-snarf.in: Changed regexp to support CPPs that insert
2285 whitespace between lexical tokens (which munges the `%%%' snarf
2288 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2290 * load.c (scm_init_load_path): Append $(datadir)/guile to
2291 %load-path, so modules do not have to be installed in Guile's
2292 current version directory.
2294 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2296 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2297 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2298 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2299 call the sysdep functions with deferred ints.
2300 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2301 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2302 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2305 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2308 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2310 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2312 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2314 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2317 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2319 * eval.c (scm_lookupcar1): New procedure to cope with a race
2320 condition during lookup (when using threads).
2321 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2322 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2325 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2327 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2328 supplied. (Change from Tim Pierce.)
2330 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2332 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2333 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2334 default and not `()'. `#f' is the canonical non-value in Scheme,
2337 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2339 * struct.c (struct_printer): New variable that holds a handle on
2340 the Scheme variable *struct-printer*. This variable can be set by
2341 Scheme code to override the printing of structures.
2342 (scm_print_struct): If struct_printer is set, call it. If it is
2343 not set, or returns #f, print the structure in the old fashion.
2344 Include "eval.h" for scm_apply.
2346 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2348 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2349 scm_struct_i_n_words to get the number of fields, not
2350 -scm_struct_n_extra_words.
2352 On the route to fancier struct printing:
2353 * struct.c (scm_print_struct): New function to print a structure.
2354 Include "genio.h" to support it. This function doesn't do
2355 anything interesting right now, but I think it should be here
2357 * struct.h: Include "print.h" and add prototype for
2359 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2360 print structures ourself.
2362 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2364 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2365 before applying the handler in case it doesn't return.
2367 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2369 * scmsigs.h, async.h: updated.
2371 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2374 * posix.c (scm_uname): interpret only negative values as an error.
2375 Solaris normally returns a positive value.
2377 * script.c (scm_compile_shell_switches): if we are not going into
2378 an interactive repl, set scm_mask_ints to zero so that asyncs can
2381 * simpos.c (scm_system): don't ignore/unignore signals around
2384 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2387 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2388 done in boot-9.scm instead.
2390 * scmsigs.c, async.c: Major rewriting of signal handling code.
2391 (scm_sigaction): new procedure.
2392 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2394 (scm_raise): return unspecified, throw error on failure.
2396 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2398 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2399 feature, to help boot-9.scm decide whether to import the regex
2402 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2404 * eval.c: Include scmconfig.h at the beginning of the file so that
2405 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2408 * regex-posix.c: #include "_scm.h" before conditionally #including
2409 <regex.h>; the former defines HAVE_REGCOMP.
2411 * regex-posix.c: #include <regex.h> conditionally, so the file is
2412 CPP'able (for dependency scanning) even on systems that don't have
2415 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2417 Add new R4RS-compliant syntax for keywords.
2418 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2419 regardless of the setting of the `keywords' read option.
2420 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2421 can be re-read no matter what the setting of the `keywords' read
2424 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2426 Add support for POSIX regular expressions.
2428 * regex-posix.c, regex-posix.h: New files. (Some code
2429 is taken liberally from rx/rgx.c in the old Guile dist.)
2431 * init.c: Include regex-posix.h.
2432 (scm_boot_guile_1): Call scm_init_regex_posix.
2434 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2435 Add regex-posix.[ch] sources.
2436 * Makefile.in: Regenerated.
2438 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2439 to do this automatically? It didn't for me, bleh.)
2441 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2443 * fports.c (print_pipe_port): New function.
2444 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2445 latter doesn't even take the right arguments.
2447 * Makefile.am: Increment shared lib revision number. I think
2448 sometimes the uninstalled Guile finds the installed shared lib;
2449 Gord says doing this might help. As things turned out, I can't
2450 say whether it does.
2451 * Makefile.in: Regenerated.
2453 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2454 passing it as the closure argument to scm_boot_guile. (Bill
2457 * ports.c (print_void_port, putc_void_port, puts_void_port,
2458 write_void_port, flush_void_port, getc_void_port, close_void_port,
2459 noop0): Use ANSI prototypes instead of K&R declarations, so the
2460 initialization of void_port_ptob gets aggressively type-checked.
2461 Fix arguments of print_void_port and write_void_port. (Bill

2495 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2497 * script.c (scm_find_executable): Use prototype-style definition
2498 here; apparently it's not quite right to have const in a prototype
2499 and then use a K&R declaration. I wonder if stuff like this will
2500 go away if we compile with -Wrequire-prototypes, or whatever that
2501 is... (Bernard URBAN)
2503 * scmhob.h: New text from Bernard URBAN.
2505 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2507 * script.c: Don't #define const on hpux. Configure takes care of
2508 this. (Thanks to Larry Schwimmer.)
2510 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2511 decide whether to #include <unistd.h>, instead of listing a bunch
2512 of systems. Don't #include stdio twice. Removed dyked-out
2513 definition of scm_find_impl_file.
2515 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2517 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2518 library version info to 1:0.
2519 * Makefile.in: Regenerated.
2521 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,
2522 gdb_interface.h, gdbint.c, gdbint.h, gh_data.c, gh_init.c,
2523 gh_io.c, gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c,

2525 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2526 throw.c: Update copyright years; these files have been worked on
2527 significantly in 1997, but only had copyright years for 1996.
2528 Also, change name of copyright holder on some from Mikael
2529 Djurfeldt to Free Software Foundation; he has signed papers
2530 assigning the changes to the FSF.
2532 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2533 reason not to give the user the option.
2535 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2536 Return #f on end-of-file when scanning table (i.e. when called
2537 with no arguments). Try to catch errors, when we can.
2538 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2540 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2541 external declarations. These are useful.
2543 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2545 * posix.c: don't include <sys/select.h> or define macros for
2546 select, since they were not used in this file.
2548 * filesys.c (scm_select): make the fifth parameter microseconds,
2549 not milliseconds. let the fourth parameter be either a real value
2550 or an integer or #f. The first, second and third arguments can
2551 now be vectors: the type of the corresponding return set will be
2553 (set_element, get_element): new static procedures.
2555 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2557 * strports.c (scm_eval_string): New function.
2558 (scm_eval_0str): Trivially re-implemented in terms of
2560 * strports.h (scm_eval_string): New extern decl.
2562 * net_db.c (h_errno): Add extern decl for this.
2564 * fports.c (local_pclose): New function.
2565 (scm_pipob): Use it in the initializer here.
2568 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2569 Use a meaningful error message when signalling an error. For
2570 this, scm_gethost must check h_errno rather than errno.
2572 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2574 * Makefile.in: Regenerated, using automake-1.1p.
2576 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2578 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2579 not SCM_UNSPECIFIED.
2581 * script.c (scm_compile_shell_switches): don't append (quit) if
2583 (scm_shell): call scm_exit_status and exit on the result of the
2586 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2588 Ensure that shared substrings are handled properly when passed to
2589 a system call or other foreign function. Many thanks to Tim
2591 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2592 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2593 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2594 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
2595 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
2596 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
2597 (scm_display_error_message): use RO macros when strings may be RO.
2598 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
2599 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
2600 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
2601 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
2602 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
2603 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
2604 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
2605 scm_strftime), vports.c (scm_make_soft_port): use
2606 SCM_COERCE_SUBSTR to make sure shared substrings are
2609 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2611 * error.c (scm_error): Add newline to error message.
2613 * init.c (scm_init_standard_ports): Doc fix.
2615 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2617 * dynl-shl.c: Completely replaced with new code from Bernard
2620 * script.c (scm_ice_9_already_loaded): New variable.
2621 (scm_compile_shell_switches): Use it.
2623 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2625 * filesys.c (scm_input_waiting_p): add missing third argument to
2628 * stime.c (scm_localtime): copy the result of localtime before
2629 calling gmtime in case they share a buffer.
2630 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2633 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2635 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2637 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2639 * Makefile.am (check-local): New target, which causes 'make check'
2640 to run gh_test_c and gh_test_repl, with some trivial input.
2641 * Makefile.in: Rgnrtd.
2643 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2645 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2648 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2650 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2651 sure how this was supposed to work.
2652 (scm_async_click): don't send SCM_TICK_SIGNAL.
2653 (scm_init_async): don't initialize %tick-thunk.
2655 * the following change doesn't affect the Scheme interface:
2656 gc-thunk is called at the end of garbage collection. however it's
2657 no longer implemented by pretending it's a signal.
2659 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2660 system async corresponding to scm_gc_thunk.
2661 * async.h: declare scm_gc_async.
2662 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2663 gc-thunk directly, instead of going through a signal handler.
2664 (scm_gc_async): new variable, points to the GC system-async.
2665 (scm_init_async): save the GC async as scm_gc_async instead
2666 of using system_signal_asyncs.
2667 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2669 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2671 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2672 Don't screw up if we're interrupted.
2673 * Makefile.in: Regeneradet.
2675 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2677 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2679 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2680 we're not using AM_INIT_GUILE_MODULE any more.
2681 * Makefile.in: Reneregated.
2683 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2685 Functions for finding variable bindings, grace à Tim Pierce.
2686 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2687 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2689 Get 'make dist' to work again.
2690 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2691 * Makefile.in: Regenerated, like a surry without a fringe on top.
2693 Changes for reduced Guile distribution: one configure script,
2695 * configure.in, configure: Removed.
2696 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2697 real configure script lives.
2698 * Makefile.in, scmconfig.h.in: Regenerated.
2700 * init.c: #include "script.h", to get prototype for script.c's
2703 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2705 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2706 scm_must_malloc, not raw malloc.
2708 * script.c (scm_compile_shell_switches): Dyke out debugging output
2711 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2713 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2715 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2716 system has them. Hope this is safe. Previously
2717 sys/timeb.h was included if HAVE_FTIME was defined or if
2718 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2719 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2721 * ioext.c (scm_setfileno): add missing third argument to
2722 scm_misc_error call.
2724 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2726 * eq.c (scm_equal_p): Correctly compare strings of different
2727 varieties. (Thanks to Tim Pierce.)
2729 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2731 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2732 #! block comment must occur on a line all by itself.
2734 Move most of the guts of shell command processing into libguile,
2735 so guile.c can be very small (and eventuallly auto-generated. (I
2736 mean, generated mechanically, not self-generated. Hmm.))
2737 * guile.c, script.c, script.h: New source files.
2738 * init.c (scm_boot_guile_1): Call scm_init_script.
2739 * libguile.h: #include "script.h".
2740 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2741 targets, for new executable.
2742 (libguile_la_SOURCES): Mention script.c.
2743 (modinclude_HEADERS): Add script.h.
2744 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2745 not dynamic linking is enabled. This is because we're generating
2746 executables now. Move CY_AC_WITH_THREADS call after those, so the
2747 values of cy_cv_threads_libs captures the libs chosen above.
2748 * Makefile.in, configure, aclocal.m4: Regenerated.
2750 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2751 We don't maintain this interface any more, and it just confuses
2754 * alloca.c: #include <scmconfig.h>, not <config.h>.
2755 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2756 it'll get included in disties.
2758 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2760 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2761 be distributed, because they confuse people.
2762 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2764 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2766 * configure.in: check for presence of gethostent (not present on
2767 OpenBSD by default).
2768 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2769 * configure, scmconfig.h.in: Regenerated.
2771 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2773 * backtrace.c (scm_backtrace): Split message string across
2774 newlines properly. GCC is more tolerant of this than other
2777 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
2779 Merge threads directory into libguile.
2780 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
2781 threads.h: New source files.
2782 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
2783 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2785 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2786 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2787 coop-threads.c.cygnus, coop-threads.h.cygnus.
2788 * configure.in: If we're using threads, include threads.o in
2790 * _scm.h, libguile.h: threads.h lives in this directory now.
2791 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2792 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2793 currently used, but brought along for information's sake.
2794 * ChangeLog-threads: log from old 'threads' directory.
2795 * Makefile.in, configure: Rebuilt.
2797 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2799 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2802 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2804 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2806 Merge GH interface library into libguile.
2807 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
2808 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2809 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2810 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2812 (EXTRA_libguile_la_SOURCES): ... here.
2813 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2814 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2815 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2816 New variables, describing how to build the gh test programs.
2817 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2818 build the test programs, and we probably should have been linking
2819 libguile.la against them all along, to support AIX shared libs.
2820 Add cflags for threads to CFLAGS; add libs for threads to new
2821 variable THREAD_LIBS, used in Makefile.am.
2822 * ChangeLog-gh: log from old `gh' subdirectory.
2823 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2825 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2827 * acconfig.h: Undo change of Apr 9; including the definition of
2828 PACKAGE in the guile headers conflicts with applications' own
2830 * scmconfig.h.in: Regenerated.
2832 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
2834 * filesys.c (scm_fcntl): New function from Roland McGrath.
2835 (scm_init_filesys): New symbols for use with fcntl.
2836 * filesys.h: Added prototype.
2838 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
2839 when PROC is receiving no arguments.
2841 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2843 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2844 have S_IFSOCK. This is the case under Ultrix.
2846 * posix.c (scm_status_exit_val, scm_status_exit_val,
2847 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2848 Ultrix versions of WIFSTOPPED, etc., which assume that their
2849 arguments are lvalues (hmm).
2851 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2853 * eval.c: Doc fixes.
2855 * throw.c: Doc fixes; rearranged.
2857 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
2859 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
2861 * acconfig.h: Added entry for PACKAGE.
2862 * scmconfig.h.in: Regenerated.
2864 Changes to work with automake-1.1n, which has better libtool support.
2865 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2866 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
2868 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
2870 * Makefile.in: Rebuild.
2872 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2874 * stime.c (scm_mktime): take an optional zone argument.
2875 (scm_localtime): check putenv return value.
2876 (scm_strftime, scm_strptime): moved from posix.c. move #include
2878 stime.h, posix.h: update prototypes.
2879 (bdtime2c, setzone, restorezone): new static procedures.
2880 (scm_mktime, scm_strftime): use them.
2881 (scm_strftime): don't call mktime before strftime. Use
2882 filltime for return value.
2883 (filltime): convert NULL zname to #f.
2884 (scm_strptime): return a count of characters consumed, not
2885 the remaining string.
2887 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2889 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
2890 (scm_mktime): likewise.
2892 Uncomment localtime and mktime.
2894 * configure.in: add AC_STRUCT_TIMEZONE.
2896 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2898 * stime.c (scm_init_stime): don't define ticks/sec.
2899 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2900 return value problem and is still portable.)
2902 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2904 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2905 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2906 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2907 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2908 cpp_err_symbols.c): Corresponding changes.
2909 * Makefile.in: Regenerated.
2911 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2913 * posix.c (scm_putenv): don't check HAVE_PUTENV.
2914 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
2915 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
2916 * putenv.c: new file, from sh-utils 1.12.
2918 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2919 since allocation isn't for Scheme objects.
2920 (scm_putenv): copy strings before placing in the environment.
2922 * stime.c (scm_current_time): throw an error if time returns -1,
2923 instead of returning #f.
2924 (scm_get_internal_real_time, scm_get_internal_real_time): use
2925 scm_long2num for return value instead of SCM_MAKINUM.
2927 * stime.h: prototypes updated.
2929 * stime.c (scm_time_in_msec): apparently unused, deleted.
2931 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2933 * configure.in: check for gettimeofday.
2935 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2936 which may be more usefully portable than a gettimeofday interface.
2938 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2940 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
2942 * Makefile.in: Regenerated.
2944 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2946 * stime.c (filltime): recovered static procedure.
2947 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
2950 * posix.h: add prototype for scm_close_pipe, remove prototypes for
2951 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2953 * posix.c (scm_mknod): split the mode argument into type and perms
2954 arguments, like the extra fields returned by stat.
2956 * fports.c (scm_pipob): set the close, free and print procedures.
2957 (scm_close_pipe): new procedure.
2959 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2960 define them in boot-9.scm
2962 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2964 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
2965 wan't defined. Don't include fd.h.
2967 * Previously fd.h was regenerated whenever configure was run,
2968 forcing a couple of files to be recompiled.
2970 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
2971 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
2972 Check for _fileno as well as _file.
2974 * ioext.c: don't fd.h.
2975 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
2978 * Change the stratigy for getting information about errno
2979 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
2980 generating lists of symbols during the build process, which will
2981 not always work, include comprehensive lists in the distribution.
2982 To help keep the lists up to date, the "check_signals" and
2983 "check_errnos" make targets can be used.
2985 * configure.in: don't check for a command to extract errno codes.
2986 * Makefile.am: update file lists, remove errnos.list and errnos.c
2987 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
2988 check_errnos targets.
2989 (CLEANFILES): remove errnos.c and errnos.list, add
2990 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
2991 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
2992 * errnos.default: deleted.
2993 * cpp_signal.c: new file.
2994 * cpp_errno.c: renamed from errnos_get.c.
2995 * cpp_err_symbols, cpp_sig_symbols: new files.
2996 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
2997 * error.c (scm_init_error): #include cpp_err_symbols instead of
2999 * posix.c (scm_init_posix): don't intern signal symbols. #include
3002 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
3004 * strop.c (scm_i_index): allow the lower bound to be equal to the
3005 length of the string, so a null string doesn't always give an error.
3007 * posix.h: new prototypes.
3008 * posix.c (scm_status_exit_val, scm_status_term_sig,
3009 scm_status_stop_sig): new functions, as in scsh. They break down
3010 process status values as returned by waitpid.
3012 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
3014 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
3015 configure doesn't know about it.
3017 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3019 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
3021 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
3022 which defines C variables with global linkage.
3024 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3026 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
3029 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
3031 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
3032 has time to check why this doesn't work well with continuations.
3034 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
3036 * Fix shell syntax error; some shells won't tolerate
3037 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
3039 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3041 * posix.c (scm_uname): throw an error if uname fails instead
3044 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
3046 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
3049 * async.c (scm_ints_disabled): definition moved from error.c.
3051 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3053 * acconfig.h: Removed PACKAGE.
3055 * scmconfig.h.in: Regenerated.
3057 * snarf.h: g++ says it's non-portable not to specify the first
3058 argument in a varargs declaration. I introduced the first
3059 argument by using preprocessor conditionals.
3061 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
3063 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
3064 (scm_freopen): use RO string macros for filename and modes.
3065 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
3067 * posix.c (scm_getgrgid): simplify conversion of name to C string.
3068 (scm_mknod): use RO string macros for path.
3070 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
3071 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
3073 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
3074 use SCM_ROSTRINGP and SCM_ROCHARS.
3076 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3078 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
3081 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
3082 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
3083 support for byte vectors.
3085 * print.c (scm_iprin1): Limit number of vector elements printed
3086 according to pstate->length.
3088 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3090 * backtrace.c (scm_display_error_message): don't segv if message
3093 * error.h: prototype for scm_error_scm.
3095 * error.c (scm_error_scm): new procedure, reimplements scm-error
3096 in C and uses scm_error.
3098 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3100 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
3101 pointer to the Scheme variable read-hash-procedures and intern it
3102 in scm_init_read. Modify scm_read_hash_extend and
3103 scm_get_hash_procedure to use the pointer.
3105 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3107 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
3108 (SCM_KEYWORD_STYLE): defined.
3110 * read.c (scm_read_opts): add a keywords option. This isn't a
3111 boolean option, in case someone wants to add support for DSSSL
3113 Setup scm_keyword_prefix symbol.
3114 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
3116 I've left keyword support disabled by default, since it doesn't
3117 seem to break the module system and it gives R4RS standard behaviour.
3118 It can be reactivated with (read-set! keywords 'prefix).
3120 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3122 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
3123 before constructing arbiter.
3125 * eval.c (scm_m_define): Bugfix: Check that the object is a
3126 closure before setting the procedure property!
3128 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
3130 * ports.c: Removed `ungetc-char-ready?'.
3132 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
3134 * read.c (scm_init_read): intitialise scm_read_hash_procedures
3135 (idea from Mikael: make it a pair so scm_permanent object only
3137 (scm_read_hash_extend): don't call scm_permanent_object.
3138 (ideas from Mikael): if chr is already in the list, replace its
3139 procedure instead of appending it again. If proc is #f, remove
3141 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
3143 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
3145 * gdbint.c (gdb_read): update scm_lreadr usage.
3147 * load.h: update prototypes.
3149 * load.c (scm_primitive_load, scm_read_and_eval_x,
3150 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
3152 * read.h: add prototype for scm_read_hash_extend. Change args for
3155 * read.c (scm_read_hash_procedures): new variable.
3156 (scm_read_hash_extend): new procedure.
3157 (scm_get_hash_procedure): new procedure.
3158 (scm_lreadr): use scm_get_hash_procedure instead of an argument
3159 for extended # processing.
3160 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
3161 scm_read_token): remove case_i, sharp arguments. Change callers.
3163 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
3165 * read.h (SCM_N_READ_OPTIONS): increase to 3.
3166 (SCM_CASE_INSENSITIVE_P): define.
3168 * read.c: add case-insensitive option to scm_read_opts.
3169 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
3170 to determine whether to convert symbol case.
3171 (default_case_i): definition removed.
3172 * read.c (scm_read_token): if case_i, downcase ic before doing
3175 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3177 * configure.in: Added configuration option `guile-debug'.
3178 Configure with --enable-guile-debug if you want a bunch of extra
3179 functions used for debugging when developing Guile.
3181 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3183 * procs.c (make-cclo): New undocumented debugging procedure: Make
3184 compiled closure with internal procedure PROC and length LENGTH.
3185 Only compiled if GUILE_DEBUG is defined.
3187 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3189 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3191 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3193 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3194 with 3 or more args internally to the evaluator.
3196 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3198 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3199 with 3 or more args internally to the evaluator. This is mainly
3200 because we don't want to pass entry and exit points of the
3201 debug support twice, but it also seems to increase the speed of
3202 the evaluator for such calls (e. g. (+ 1 2 3)).
3204 * backtrace.c (scm_display_application): New procedure:
3205 display-application; Set fancy printing parameters individually
3206 for different types of display (backtrace, error, application).
3207 (These should of course be customizable!)
3209 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3210 clear the CHECK-flags.
3212 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3214 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3216 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3218 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3219 from pairs with a GLOC in the car.
3221 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3222 otherwise `symbol-hash' will behave badly.
3223 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3224 we get segmentation fault!
3226 * symbols.c: Added #include "weaks.h". New functions:
3227 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3228 moved to an extraneous library when we split libguile.)
3230 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3232 * filesys.c (scm_stat): stat now takes fport arguments too as
3233 documented in the manual.
3235 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3237 * debug.c (scm_single_step): Bugfix: Call continuation with
3238 scm_call_continuation instead of throwing to it.
3240 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3242 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3243 argument wasn't declared to be optional.
3245 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3247 * stime.c (scm_init_stime): Add feature "current-time".
3249 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3251 * throw.h: prototype for scm_exit_status.
3252 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3253 args to derive an exit status. Allows (quit) to work from a
3255 (scm_exit_status): new function.
3258 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3260 * eval.c (scm_deval): Removed some old code.
3261 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3263 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3266 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3269 * procs.c: Introduce the existent C function scm_thunk_p at the
3270 Scheme level as well.
3272 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3274 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3275 used from C to easily lookup the value of a symbol in the current
3278 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3280 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3281 scm_init_unif in this file. This will also fix a previous problem
3284 * configure.in: Added AM_MAINTAINER_MODE
3286 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3288 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3291 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3293 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3294 source files that are not always included in libguile but should
3295 have their dependencies calculated by automake. This variable is
3296 recognized by automake, no further magic is needed.
3297 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3298 to deal exclusively with *.lo files, as it seems. The *.o files
3299 are built automatically when the corresponding *.lo file gets
3302 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3304 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3307 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3309 * unif.c (scm_array_set_x): minor change to argument error checking.
3311 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3313 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3314 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3315 They should only be included in the library at configure.in's
3317 (libguile_la_LDADD): Include the appropriate .lo files here.
3318 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3319 so we know when to build them (and their .lo bretheren).
3320 * configure.in (LIBLOBJS): New substituted variable. We let
3321 configure decide which .o files to include in LIBOBJS, and then
3322 put the corresponding list of .lo files in LIBLOBJS. The latter
3323 is what we pass to libtool.
3324 * Makefile.in, configure: regenerated.
3326 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3328 * symbols.c (scm_sysintern0): New function. Contains the core of
3329 old scm_sysintern but doesn't take a second value argument.
3330 (scm_sysintern): Now uses scm_sysintern0.
3331 (scm_sysintern_no_module_lookup): Renamed to
3332 scm_sysintern0_no_module_lookup and doesn't take a second value
3333 argument any longer.
3335 * symbols.h (scm_sysintern0: Added declaration.
3337 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3338 scm_sysintern when interning option keys. Otherwise we risk
3339 destroying the values of already interned variables.
3341 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3342 scheme-level boolean (use SCM_NFALSEP).
3344 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3346 (scm_backtrace): New function. (C version of old function from
3347 boot-9.scm) Motivation: Make it possible to display backtraces
3348 without depending on boot-9.scm. (I'm uncertain if this
3349 motivation is good enough...)
3351 * root.h (scm_root_state): Add member the_last_stack_var.
3352 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3354 * root.c (mark_root): Mark scm_the_last_stack_var.
3356 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3359 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3361 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3362 1. mark_lazy_catch didn't mark the smob.
3363 2. Both functions above have standard variants:
3364 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3365 free_lazy_catch --> scm_free0.
3367 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3369 * throw.c (scm_internal_lazy_catch): New function.
3370 (scm_lazy_catch): Rewritten to use it.
3371 (scm_ithrow): Handle the new lazy catch representation.
3372 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3373 that doesn't have a jmpbuf is a lazy catch clause.
3374 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3375 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3376 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3378 (scm_init_throw): Register the new lazy-catch smob type.
3379 * throw.h (scm_internal_lazy_catch): decl for new function.
3381 * throw.c (scm_internal_catch): Doc fixes.
3383 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3384 configure.in. Including this might cause problems if applications
3385 that link against libguile include their own copies of alloca, but
3386 if they're using autoconf, they should be adding libguile to LIBS
3387 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3388 the copy in libguile, and things will be okay. (I think.)
3390 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3392 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3394 strop.h: move prototypes too.
3396 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3398 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3401 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3402 etc. I deleted them from filesys.c long ago, but didn't
3403 notice they were here too (although ineffective since
3404 sys/stat.h wasn't included).
3406 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3408 * eval.c: Don't define alloca in GCC case. gcc will automatically
3409 use __builtin_alloca if appropriate.
3411 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3413 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3414 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3415 that values of automatic variables are preserved. See comments
3416 for safe_setjmp for details.
3418 Change from Thomas Morgan:
3419 * variable.c: Include eq.h.
3420 (var_equal): New function.
3421 (variable_smob): Use var_equal as the discriminator for variables.
3423 * throw.c (s_throw): Remove extraneous declaration.
3425 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3426 * eval.c: Add necessary CPP cruft to support that.
3427 * configure, Makefile.in, scmconfig.h.in: regenerated.
3429 Change from Thomas Morgan:
3430 * procprop.c (scm_procedure_properties): Convert the Scheme
3431 boolean returned by scm_procedure_p into a C boolean before using
3432 it as a condition for SCM_ASSERT.
3433 (scm_procedure_property): Likewise.
3435 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3436 indications of Unixness.
3439 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3441 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3443 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3445 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3446 "unknown # object" error messages.
3448 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3449 (scm_i_index) and declare it static. Add a 'direction' argument
3450 to indicate what way the search should go.
3451 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3453 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3454 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3456 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3458 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3460 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3461 to avoid clash with various scsh forks.
3463 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3465 The following two changes (ramap.c, throw.c) are motivated by the
3466 apparent unportability of forward declarations of static arrays of
3467 the form `static foo bar[];'.
3469 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3470 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3472 * throw.c (scm_throw): Moved above scm_ithrow.
3474 * options.h: Removed the extern declarations of scm_yes_sym and
3475 scm_no_sym since these are static.
3477 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3479 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3481 * Makefile.am: remove AWK=@AWK@.
3482 Add a rule for generating errnos.list.
3483 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3485 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3486 don't extract errnos, just set a variable (avoids the
3487 need to recompile error.c just because configure is run.)
3489 * unif.h: update prototypes.
3490 * unif.c (scm_uniform_array_read,write): change the offset and
3491 length arguments to start and end, for consistency.
3493 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3495 * ioext.h: update prototypes.
3496 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3497 scm_read_line_x, it's a more general procedure using an
3498 interface from scsh. read-line and read-line! are now defined
3500 Note that the new read-line trims the terminator
3501 by default, previously it was appended to the returned string. An
3502 optional argument specifies how to process the terminator (scsh
3503 compatible). For the old behaviour: (read-line port 'concat).
3504 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3505 returns a pair, but is converted to multiple values if the scsh
3508 socket.h: update prototypes.
3509 * socket.c (scm_recvfrom): for consistency with other procedures,
3510 take start and end as separate optional arguments.
3511 (scm_recv, scm_recvfrom): don't allow the second argument
3512 to be a size, only a buffer. Change the scheme names to
3513 recv! and recvfrom!. Don't return the buffer.
3515 * ioext.h, posix.h: move prototypes too.
3516 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3517 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3518 "read.h" and "unif.h".
3519 * ioext.c: include "chars.h"
3521 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3523 * dynl.c: The dynamic linking and module registration functions
3524 are now defined even when dynamic linking is not available for the
3525 host system. Some of their functionality can be done without
3526 dynamic linking; when it's really needed, they throw errors.
3528 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3530 * configure.in: Only define DYNAMIC_LINKING when one of the system
3531 dependent functions is detected.
3532 * dynl.c (scm_dynamic_func): New function to get the address of a
3533 function in a dynamic object.
3534 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3535 produced by scm_dynamic_func as the thing to call.
3537 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3539 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3540 (scm_register_module_xxx, scm_registered_modules,
3541 scm_clear_registered_modules): New functions.
3543 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3545 * symbols.c (scm_sysintern): Renamed to
3546 scm_sysintern_no_module_lookup.
3547 (scm_sysintern): New function to take the place of the old
3548 scm_sysintern. It uses the current toplevel lookup closure to give
3549 the symbol its value. This is a temporary hack to put packages
3550 like gtcltk into their own module.
3551 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3552 us whether `scm_top_level_lookup_closure_var' has been initialized
3554 * eval.c (scm_init_eval): Set it.
3556 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3558 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3559 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3561 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3563 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3564 scm_sys_dup): deleted: FD capability will be added to other
3566 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3567 scm_fd_free, fd_smob, scm_intern_fd.
3568 (scm_open): renamed from scm_sys_open. Return a port instead of
3569 an FD object. Make the mode argument optional.
3570 (scm_sys_create): deleted, it's just a special case of open.
3571 (scm_init_filesys): move interning of constants O_CREAT etc.,
3572 here (were previously using SCM_CONST_LONG macro).
3573 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3575 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3576 include "fports.h" and <stdio.h>
3577 (scm_stat, scm_select): don't support FD objects.
3579 * error.h: adjust scm_syserror_msg prototype.
3580 * error.c (scm_syserror_msg): take an extra argument for errno.
3581 Using the global value didn't always work, since it could be
3582 reset by procedure calls in the message or args arguments.
3584 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3585 I don't understand why the check was there (and what about the
3588 * strop.c (scm_string_copy): allow shared substrings to be copied.
3590 * unif.h: corresponding change to prototypes.
3591 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3592 recognize two new optional arguments: offset and length. Allow
3593 the port argument to be an integer (file descriptor, for scsh).
3594 Include <unistd.h> for "read" prototype.
3596 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3598 * socket.c: don't include filesys.h.
3600 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3602 * Makefile.am: add AWK=@AWK@ (?)
3604 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3606 Add a rule to generate errnos.c from errnos.
3607 * error.c (scm_init_error): include errnos.c.
3608 * errnos_cnvt.awk: new file, converts the list of errno codes to
3610 * errnos_get.c: new file.
3611 * errnos.default: new file, contains errnos to try if they can't
3612 be extracted from errno.h.
3613 * configure.in: if using GCC, try and extract errno codes from
3617 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3619 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3620 * Makefile.am: Made libguile into a libtool library.
3621 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3622 Set libtool_libs to indicate that libguile is a libtool library.
3623 See guile/ChangeLog for details.
3624 * .cvsignore: ignore "*.lo", the libtool library objects.
3626 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3628 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3629 use htons in getservbyport argument.
3631 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3633 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3634 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3637 * objprop.c (scm_object_property): No need to take the CDR of the
3638 value returned by scm_object_properties, since Aug 20 change.
3640 * configure.in: When checking for struct linger, #include
3641 <sys/types.h> as well as <sys/socket.h>. I've never known
3642 <sys/types.h> to cause any portability problems, and Solaris's
3643 <sys/socket.h> needs it.
3644 * configure: Rebuilt.
3646 I think the Sun compiler has chosen a perverse way to interpret
3647 ANSI declarations combined with K&R definitions. We'll
3648 appease it a little bit. But when it invades France, we fight.
3649 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3650 * print.h (scm_iprlist): Here too.
3651 * numbers.c (scm_divbigdig): Change definition to match
3652 declaration in numbers.h.
3653 * unif.c (scm_makflo): Change definition to match declaration in
3656 * init.c (scm_boot_guile): Don't return the value of
3657 scm_boot_guile_1. This function doesn't return a value;
3658 scm_boot_guile_1 doesn't return a value (or return at all).
3660 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3663 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3664 compile. I have a feeling this function is a bad idea anyway ---
3665 one should always test for features, not systems.
3667 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3668 semicolons. Only pure luck kept this from being noticed earlier.
3670 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3672 * socket.c (scm_recvfrom): Added missing semicolon.
3674 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3676 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3677 the buffer and start and end positions for scsh networking
3680 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3682 * configure.in: Revert previous change to this file; the problem
3683 is due to transient automake weirdness.
3684 * configure: Rebuilt.
3686 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3687 PLUGIN/guile.libs. configure generates the latter from the former.
3688 * Makefile.in: Rebuilt.
3690 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3691 need this if we install scripts, like guile-snarf.
3692 * configure: Rebuilt.
3694 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3696 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3698 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3700 * socket.c (scm_addr_vector): fix faulty scm_listify.
3702 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3704 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3705 style block comment is no longer considered an error.
3707 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3709 * PLUGIN/guile.libs.in: New file.
3710 * PLUGIN/guile.libs: Removed from repository.
3711 * configure.in: Create PLUGIN/guile.libs from
3712 PLUGIN/guile.libs.in. This is for including additonal libraries
3713 needed for dynamic linking.
3714 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3715 instead of PLUGIN/guile.libs.
3717 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3719 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3721 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3722 occurrences of the given element from the list, not just the
3723 first. This is how the Emacs Lisp functions behave, how the
3724 analogous Common Lisp functions behave, and (I believe) how the
3725 older Maclisp functions worked. I realize that this change may
3726 break code, but it seemed better to break it before the Guile
3729 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3730 Their prototypes were already present in gc.h, but they weren't
3732 (scm_init_storage): Initialize scm_protects.
3733 * root.c (scm_protects): New element of scm_sys_protects.
3735 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3737 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3739 * libguile.h: Added #include "libguile/net_db.h".
3741 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3742 30 change. That file is only meant for communication between the
3743 configuration process and load.c. If code linked against libguile
3744 wants to get at the paths mentioned in libpath.h, it can call
3745 functions declared in load.h.
3747 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3749 * libguile.h: Removed #include "libguile/fdsocket.h"
3751 * net_db.c: Added #include <sys/socket.h>.
3753 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3755 * filesys.c (scm_input_waiting_p): use select in preference to
3756 FIONREAD, since the latter doesn't detect EOF.
3757 Throw error if neither select nor FIONREAD available.
3759 * socket.c (scm_connect): take a port, not a fd object.
3760 (scm_fill_sockaddr): throw an error if fam is not recognised.
3761 (scm_bind): use scm_fill_sockaddr.
3762 (scm_listen): take a port, not a fd object.
3763 (scm_accept): take and return a port. return #f in the car if
3764 address can't be got
3765 (scm_sock_fd_to_port): new procedure.
3766 (scm_socket): use scm_sock_fd_to_port.
3767 (scm_addr_vector): throw error if unrecognised address type.
3768 take an extra argument with the calling procedure name.
3769 (scm_getsockname): take a port. return #f if address can't be got.
3770 (scm_getpeername): take a port. return #f if address can't be got.
3771 (scm_recvfrom): take a port. return #f for address component if can't
3773 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3774 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3776 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3778 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3779 use separate data pointers, to allow them to be designed
3780 independently and reused.
3781 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3782 Renamed from catch_body, catch_handler, and uncaught_throw; made
3784 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3786 (scm_catch): Use the above.
3787 (scm_throw): Don't bother printing a message for an uncaught
3788 throw; we establish a default handler in init.
3789 * throw.h (scm_internal_catch): Prototype updated.
3790 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3792 (struct scm_body_thunk_data): New structure, used as data
3793 argument to scm_body_thunk.
3794 * init.c (struct main_func_closure): New structure, packaging up
3795 the data to pass to the user's main function.
3796 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3797 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3798 scm_internal_catch to establish a catch-all handler, using
3799 scm_handle_by_message. This replaces the special-case code in
3801 (invoke_main_func): Body function for scm_internal_catch; invoke
3802 the user's main function, using the main_func_closure pointer to
3803 decide what to pass it.
3804 * root.c (struct cwdr_body_data): Remove handler_proc member.
3805 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3806 (cwdr_handler): Removed.
3808 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3810 * socket.h (SCM_P): update bind prototype.
3811 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3812 include "feature.h".
3813 (scm_socket): return a port, not a file descriptor object.
3814 include "fports.h" and <unistd.h>
3815 (scm_bind): take a port, not a file descriptor object.
3816 take an extra argument for address args.
3818 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3819 INADDR_NONE, INADDR_LOOPBACK.
3821 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3823 * init.c: include net_db.h and not fdsocket.h.
3824 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3826 * Makefile.am: corresponding changes.
3827 * socket.h: renamed from fdsocket.h, fix names.
3828 * net_db.h: renamed from socket.h, fix names.
3829 * socket.c: renamed from fdsocket.c.
3830 remove _sys from procedure names.
3831 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3832 add "socket" to features list.
3833 * net_db.c: renamed from socket.c.
3834 remove _sys from procedure names.
3835 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3836 add "net-db" to features list.
3837 include "net_db.h". don't include <sys/socket.h> or
3840 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3842 * tags.h (scm_tags): Removed comma at end of last enumerator.
3844 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3846 Don't use GCC extensions to allocate space for debugging frames.
3847 (Here he goes again! Why do we put up with this?!)
3848 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3849 an scm_debug_info structure, not an in-line array of them. Add
3850 'info' member, to say how many vect elements we've used, for eval
3852 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3853 a new variable debug_info_end to mark the end of vect, instead of
3854 the address of the 'info' pointer itself.
3855 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3856 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3857 (SCM_APPLY): Explicitly allocate space for debug.vect.
3858 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3859 * stacks.c: Adjusted for new debug frame structure.
3860 (RELOC_INFO, RELOC_FRAME): New macros.
3861 (stack_depth, read_frames): Use them, and new scm_debug_frame
3862 element 'info', instead of magically knowing that eval frames have
3863 an info pointer sitting after vect.
3864 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3866 (scm_init_stacks): Formatting tweaks.
3868 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3870 Give GCC more control flow information, so it can be sure that
3871 variables aren't used uninitialized.
3872 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3873 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3874 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3875 scm_misc_error): Tell GCC that these functions never return.
3876 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3877 out the field type, call abort if SCM_ASSERT returns, to placate
3879 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3880 scm_wta ever returns. We can't handle this case anyway, and this
3881 gives the optimizer more information.
3882 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3883 scm_wta ever returns.
3885 In some cases, the code is fine, but GCC isn't smart enough to
3886 figure that out; this usually happens when one variable is only
3887 initialized and used when a particular condition holds true, and
3888 we know that condition will never change within a given invocation
3889 of the function. In this case, we simply initialize the variables
3890 to placate the compiler, hopefully to a value which will cause a
3891 crash if it is ever actually used.
3892 * print.c (scm_iprin1): Initialize mw_pos.
3893 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3894 * throw.c (scm_ithrow): Initialize dynpair.
3895 * unif.c (scm_uniform_vector_ref): Initialize cra.
3896 * struct.c (init_struct): Initialize prot.
3897 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3899 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3900 if EXPR contains no expressions.
3902 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3904 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3905 cause an infinite loop (???). So much for the algebraic
3906 equivalency of variable-sized arrays and alloca...
3908 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3910 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3911 a SCM boolean, not a C boolean.
3913 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3915 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3916 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3917 rules for raising scm_mtrigger. Previously, unfortunate but not
3918 unlikely circumstances could result in almost constant invokation
3919 of the gc. Now, this situations should be less likely, but they
3920 are not prevented completely.
3922 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3924 * numbers.c (scm_fuck): Procedure removed; looks like old test
3926 * numbers.h: Prototype removed.
3928 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3930 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3931 array to a pointer, to match my Nov 21 change in eval.c.
3933 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3935 * libguile.h: Added #include "libguile/backtrace.h", #include
3936 "libguile/stacks.h".
3938 * strings.c (scm_string scm_make_string scm_string_ref
3939 scm_string_set_x scm_string_equal_p scm_string_append):
3940 Bugfix according to scm patch from Aubrey Jaffer:
3941 Corrected long-standing
3942 (not (eqv? (integer->char 128)
3943 (string-ref (make-string 1 (integer->char 128)) 0)))
3944 bug found by John Kozak <jk@noontide.demon.co.uk>.
3946 * strports.c, strports.h: Make scm_eval_0str return the value of
3947 the last expression evaluated (previously, it returned void).
3949 * strports.c, strports.h: New function: scm_read_0str. Does what
3952 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3954 * simpos.c (scm_getenv): return #f if string can't be found in the
3955 environment instead of throwing an exception, for compatibility
3956 with numerous other systems.
3958 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3960 * Makefile.am (.c.x): Use guile-snarf.
3961 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
3963 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
3965 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3967 * backtrace.c (scm_display_error_message): Made non-static, and
3968 renamed from display_error_message.
3969 * backtrace.h (scm_display_error_message): Added extern decl.
3970 * throw.c (uncaught_throw): Use it to display the error message.
3972 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
3974 * inet_aton.c: Use #if 0, not #ifdef 0.
3976 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
3978 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
3979 to convert the returned value.
3980 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
3981 the offset argument.
3983 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3985 Add new interface to catch/throw, usable from C as well as
3987 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
3988 (scm_internal_catch): New function, replaces...
3989 (scm_catch_apply): Deleted.
3990 * throw.c (scm_catch_apply): Deleted; replaced with a more general
3991 mechanism which is a bit more code, but can be used nicely from C
3992 and implement the Scheme semantics as well.
3993 (scm_internal_catch): This is the replacement; it's named after
3994 the analogous function in Emacs.
3995 (scm_catch): Reimplemented in terms of the above.
3996 (struct catch_body_data, catch_body, catch_handler): New
3997 functions, used by scm_catch.
3998 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
3999 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
4000 support for new cwdr.
4002 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
4005 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
4007 * acconfig.h: Added DYNAMIC_LINKING symbol.
4008 * configure.in: Add option and checks for dynamic linking.
4009 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
4010 dynl.h: New files for dynamic linking support.
4011 * Makefile.am (libguile_a_SOURCES):
4013 (modinclude_HEADERS): Added "dynl.h".
4014 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
4016 * init.c (scm_boot_guile_1): Call
4017 scm_init_dynamic_linking to initialize dynamic linking support.
4019 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
4021 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
4022 (as we Schemers say). It needs to be global, so that I can tweak
4023 it for the proper operation of unexec.
4024 (scm_boot_guile_1_live): New variable, see above.
4026 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
4028 * guile-snarf.sh: Removed.
4029 * PLUGIN/guile.libs: Added dependency for -lm.
4030 * acinclude.m4: Renamed from aclocal.m4.
4031 * PLUGIN/greet: Removed.
4032 * Makefile.am, aclocal.m4: New files.
4033 * configure.in: Updated for Automake.
4035 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
4037 * eval.c (scm_definedp): Use top_level_lookup_closure_var
4038 and not top_level_lookup_thunk_var.
4040 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
4042 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
4044 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
4046 * eval.c (scm_definedp): Incompatibly changed to be a builtin
4047 Scheme function, instead of syntax. Single argument is now a
4050 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4052 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
4053 scm_ra_divide): Properly terminate statements passed as arguments
4054 to IVDEP macros. (Thanks to Bernard Urban.)
4056 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
4057 with non-constant sizes. (Thanks to Bernard Urban.)
4059 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4061 It's an "eval closure", not an "eval thunk." A thunk is a
4062 function of no arguments.
4063 * root.h (struct scm_root_state): Renamed
4064 top_level_lookup_closure_var from top_level_lookup_thunk_var.
4065 (scm_top_level_lookup_closure_var): Renamed from
4066 scm_top_level_lookup_thunk_var.
4067 * root.c (mark_root): Uses changed.
4068 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
4069 * init.c (scm_start_stack): Uses changed.
4070 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
4071 Change scheme-visible name to *top-level-lookup-closure* from
4072 *top-level-lookup-thunk*.
4074 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
4076 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
4077 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
4079 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
4081 * gc.c (struct scm_heap_seg_data): Doc fixes.
4083 * gc.c (scm_gc_sweep): Empty all segments' freelists before
4084 sweeping. Then, prepend each segment's free cells to its
4085 freelist, rather than wiping out the old value. (Thanks to Marius
4088 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
4089 scm_check_freelist, scm_debug_newcell): New functions and
4090 variables, for debugging freelist problems.
4091 * pairs.h (SCM_NEWCELL): New debugging version added.
4092 * gc.h (scm_debug_newcell): Added extern declaration, used by
4093 debugging version of SCM_NEWCELL.
4095 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4097 On some systems <libc.h> conflicts with <unistd.h>, and should not
4098 be #included at all.
4099 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
4100 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
4101 * configure.in: Call it.
4102 * posix.c, filesys.c: Use its results to decide whether or not to
4104 * configure, scmconfig.h.in: Rebuilt with autoconf and
4107 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4109 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
4110 pointer to the stdio stream before calling scm_setbuf0, so the
4111 latter will be able to retrieve it. I'm surprised this didn't
4112 segfault earlier. (Thanks to Christopher Lee.)
4114 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4116 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
4119 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4121 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
4122 number of stack narrowing specifier pairs. The first specifier in
4123 a pair controls inner border, the second the outer border. A
4124 number means cut that number of frames, a procedure object means
4125 cut until that object is found in operator position in a frame.
4127 * root.c (cwdr): Bugfix.
4129 * read.c: Recording of positions disabled by default.
4131 * procs.c (scm_closure_p): New function.
4133 * posix.c (scm_tmpnam): New function.
4135 * load.c: Added #include "throw.h".
4136 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
4139 * load.c, load.h (scm_read_and_eval_x): New function.
4141 * eval.c: Renamed debug option "deval" to "debug".
4143 (scm_eval_x): `eval!' is no longer accessible from the scheme
4144 level. Motivation: We can't allow operations which introduce
4145 glocs into the scheme level. Guile's type system can't handle
4146 these as data. Use `eval' or `read-and-eval!' as replacement.
4148 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
4149 SCM_CONSP since this is a macro!; Set vframe.prev to
4150 scm_last_debug_frame instead of 0. In this way we can look
4151 "above" the virtual start stack frame if we wish.
4152 (scm_debug_hang): New function: Useful for debugging Guile in
4153 certain tricky situations. Will probably be removed later...
4155 * debug.h: Changed semantics of debug option "backtrace". This
4156 option now only indicates whether we want automatic backtrace at
4159 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4161 * ports.c: #include "filesys.h"
4162 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
4164 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
4165 Motivation: This is system specific code which is related to file
4166 I/O. It also may use select. Added code by Gary Houston to
4167 detect presence of character in stdio buffers.
4169 * libguile.h: #include "libguile/libpath.h"
4171 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4172 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4173 SCM_SITE_DIR; Install libpath.h among the other include files.
4175 * load.c, load.h (scm_sys_package_data_dir): New function.
4177 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4179 * stacks.h: Bugfix: Don't use tail-array length field as stack
4180 length field! This screwed GC.
4182 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4184 * _scm.h: Added #ifndef around definition of macros min and max.
4186 * __scm.h: Added hooks for threads to plugin to in ints protection
4187 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4188 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4189 the main code in these macros duplicated and spread over multiple
4190 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4191 SCM_THREAD_SWITCHING_CODE.
4193 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4195 * snarf.h: New file.
4196 * guile-snarf.sh: New file.
4197 * Makefile.in (inner_h_files): Added snarf.h
4198 (ancillary, install, uninstall, distclean): Added actions for
4200 (.c.x): Use guile-snarf.
4201 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4202 (gen_c_files): Note that these depend on guile-snarf.
4203 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4204 now in "snarf.h". Added #include "snarf.h" to get them.
4205 * libguile.h: Added #include "snarf.h".
4206 (Patches applied and tweaked by Jim Blandy.)
4208 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4210 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4211 standards suggest against providing prototypes for system
4212 functions. Thanks to Greg Troxel.
4214 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4216 * strports.c (scm_eval_0str): New function.
4217 #include "read.h", to get prototype for scm_read.
4218 * Makefile.in (strports.o): Update dependencies.
4219 * strports.h: New prototype.
4221 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4222 scheme name from "int?" to "integer?". It seems to do the job.
4223 * numbers.h: Rename prototype too.
4224 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4227 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4228 scm_num_eq_p): Rename these according to R4RS conventions: call
4229 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4230 to making libguile R4RS compliant without ice-9...
4232 * load.c (scm_sys_search_load_path): Search for files under all
4233 extensions listed in the %load-extensions variable. If FILENAME
4234 is absolute, return it unchanged, without searching the load path.
4235 (scm_loc_load_extensions): New variable, pointing to
4236 %load-extensions' value cell.
4237 (scm_init_load): Initialize it, and the value it points to.
4238 (scm_primitive_load_path): Improve error reporting.
4240 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4241 of new Scheme variable %load-hook.
4242 (scm_primitive_load): Apply %load-hook to filename.
4244 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4246 * configure.in: add tests for figuring out whether buffered data
4247 is available in a FILE structure, which is needed by char-ready.
4249 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4252 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4253 exceptions using misc_error instead of syserror. It seems a bit
4254 odd to throw an exception if a string can't be found in the
4255 environment, but it's consistent with open-file, stat etc.
4256 (simpos.h): remove sys_ from getenv.
4258 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4259 occurs, throw an error instead of returning errno. Return value
4261 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4263 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4265 * filesys.c (scm_stat2scm): derive file type and permissions from
4266 the stat mode and append them to the returned vector.
4267 There isn't much overhead in doing this and it avoids the need to
4268 work with S_IRUSR et al. in Scheme.
4269 Define symbols scm_sym_regular etc.
4270 (scm_init_filesys): don't intern S_IRUSR etc.
4272 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4273 and s_primitive_load_path.
4275 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4277 * error.h: don't declare error symbols. prototype for scm_misc_error.
4279 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4282 * error.c: use SCM_SYMBOL to set up error keys.
4283 scm_misc_error: new procedure.
4285 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4287 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4288 between `#!' and `!#' is ignored.
4289 (skip_scsh_block_comment): New function.
4291 * feature.c (scm_set_program_arguments): New argument, FIRST.
4292 * feature.h: Update prototype.
4293 * init.c (scm_boot_guile_1): Pass new argument to
4294 scm_set_program_arguments.
4296 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4298 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4299 (scm_boot_guile): Call scm_set_program_arguments here, later than
4300 the old initialization.
4302 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4303 initialization procedure.
4304 - Delete in, out, err arguments; there are other perfectly good
4305 ways to override these when desired.
4306 - Delete result argument; this function shouldn't ever return.
4307 - Rename init_func argument to main_func, for less confusion.
4308 - Delete boot_cmd argument; main_func is more general.
4309 -Add 'closure' argument, to help people pass data to main_func
4310 without resorting to global variables.
4311 - Abort if reentered; don't bother returning an error code.
4312 - Call scm_init_standard_ports to set up the default/current
4313 standard ports; no need to pass them to scm_start_stack.
4314 - Remove code to evaluate the boot_cmd, and start the repl; let
4315 the user do something like that in main_func if they want.
4316 - Remove code to package up a return value; main_func can do any
4318 - Call exit (0), instead of returning.
4319 (scm_start_stack): Don't initialize the I/O ports here; that's
4320 weird. Delete in, out, err arguments. Move guts to
4321 scm_init_standard_ports, scm_stdio_to_port.
4322 (scm_init_standard_ports): New function, to set up current and
4323 default standard ports.
4324 (scm_start_stack, scm_restart_stack): Make these static.
4325 * init.h (scm_boot_guile): Adjust declaration.
4326 (scm_start_stack, scm_restart_stack): Remove externally
4327 visible declarations for these.
4328 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4330 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4331 written out several times in scm_start_stack.
4332 * fports.h: New declaration for the above.
4334 * feature.c (scm_set_program_arguments): New function.
4335 * feature.h: New declaration for the above.
4337 * ports.c: Formatting tweak.
4339 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4341 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4342 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4343 for obtaining the address of a car or cdr field. Motivation:
4344 &SCM_CXR make assumptions about the internal structure of the
4347 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4348 Motivation: see SCM_CXRLOC.
4350 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4351 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4352 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4353 Motivation: Safer use. Some other macros are defined in terms of
4354 these operations. If these are defined using the SCM_SETCXR
4355 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4356 to inefficiency and an <e1> with side-effects could potentially
4357 break. Also, these particular operations are heavily utilized in
4358 the garbage collector. In unoptimized code there will be a
4361 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4362 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4363 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,

4366 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4367 vports.c: Cleaned up use of pairs: Don't make any special
4368 assumptions about the internal structure of selectors and
4369 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4370 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4371 (Among other things, this change makes it easier to build Guile
4372 with certain compilers which have problems with casted lvalues.)
4374 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4376 * stacks.c: Improve selection of relevant stack frames when making
4377 a stack object. Introduce one level of indirection in the stack
4378 object to make it possible to "narrow" to a certain region of the
4379 stack. This facilitates making use of more clever algorithms (not
4380 implemented) for selecting relevant frames and gives a cleaner
4381 design since selection of frames can be done independently of
4382 extraction of frames from the real stack.
4383 (scm_stack_id): Also take #t as argument which means look at
4386 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4387 Turn n_tail into an integer directly representing current number
4388 of frames in stack. Add field tail.
4390 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4392 * debug.c (scm_make_memoized): Made it available at scheme level.
4393 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4394 SCM_NIMP before applying heavier predicates in argument checking.
4395 (scm_local_eval): Also take memoized object as argument.
4397 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4398 aren't created with zero length, but should such a strange
4399 creature suddenly turn up...
4401 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4403 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4404 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4406 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4408 * variable.c (scm_make_variable): Make the name hint optional, as
4410 (anonymous_variable_sym): Renamed from variable_sym. All uses
4413 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4414 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4415 of scm_primitive_load_path was also changed to
4416 "primitive-load-path", from "%try-load-path". Callers changed.
4417 We'd like to respect the convention that a function named
4418 "try-mumble" should behave just like the function called "mumble",
4419 but return #f instead of signalling some error.
4420 * load.h: Rename prototypes.
4422 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4424 * print.c (make_print_state, grow_print_state), print.h: Modified
4425 the print state representation: Don't use a tail array for
4426 recording of circular references. Resizing of the print state
4427 structure invalidates the print state pointer. To avoid passing
4428 around an indirect print state reference to all printing
4429 functions, we instead let the print state reference a resizable
4432 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4434 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4435 Don't crash when passed an improper list terminated by a
4436 non-immediate value.
4438 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4440 Allocate data for structures on an eight-byte boundary, as
4441 required by the tagging system.
4442 * struct.c (alloc_struct): New function.
4443 (scm_make_struct, scm_make_vtable_vtable): Call it.
4444 * struct.h (scm_struct_n_extra_words): Bump to 3.
4445 (scm_struct_i_ptr): New "field".
4446 * gc.c (scm_gc_sweep): When we need to free the data, use the
4447 information stored by alloc_struct to find the beginning of the
4448 block allocated to the structure, so we can free it.
4450 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4452 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4455 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4456 (scm_debug_info): New member: id.
4458 * stacks.c: Stacks are now represented as structs; Stacks have an
4459 id given to them by `start-stack'.
4460 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4462 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4463 Changed stack representation.
4465 * debug.c (scm_procedure_name): Try procedure property `name' for
4466 compiled closures aswell.
4468 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4470 * eval.c: scm_i_name moved to gsubr.c
4471 (scm_m_define): Record names of all kinds of procedure
4472 objects. (Earlier, only closures were recorded.)
4474 * procprop.h: Added declaration of scm_i_name.
4476 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4477 (scm_make_gsubr): Record names of compiled closures.
4479 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4481 * debug.c, debug.h: Removed obsolete code.
4483 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4484 stacks.c: Renamed regs --> scm_contregs.
4486 * print.c (scm_free_print_state): Cleanup print state before
4487 returning it to pool. It is better to do it here than in
4488 scm_prin1 since scm_prin1 is called often.
4490 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4491 s_set_source_property_x): Check that first argument is a pair or a
4494 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4495 scm_i_line, scm_i_column and scm_i_breakpoint global.
4497 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4498 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4501 * debug.h: Added debug object smob declaration and macro
4504 * configure.in: Build with backtrace.o and stacks.o if debug
4507 * Makefile.in: Added entries for new files: backtrace.c,
4508 backtrace.h, stacks.c and stacks.h.
4510 * symbols.c (scm_sym2ovcell): Fixed documentation.
4512 * _scm.h (min, max): Added.
4514 * async.c: Moved `min' macro to _scm.h.
4516 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4517 SCM_BACKTRACE_INDENT.
4519 * eval.c: Added new debug options `maxdepth' and `indent'.
4521 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4523 * print.h: Added selector SCM_PRINT_STATE.
4525 * print.c: New functions: scm_make_print_state,
4526 scm_free_print_state.
4528 * print.h: Added declarations for scm_make_print_state,
4529 scm_free_print_state.
4531 * debug.c (scm_m_start_stack): New acro.
4533 * debug.h: Small cleanup.
4535 * init.c (scm_boot_guile_1): Moved scm_init_debug below

4563 More prototype-related changes from Marius Vollmer:
4564 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4565 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4566 * ports.h (ptobfuns): Added prototypes. This means some casting in
4568 * fports.c: Added casts for initializations, since the functions
4569 are defined to take FILE * as their stream argument, not SCM.
4570 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4571 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4572 to `char *str_data' to conform to prototype.
4574 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4576 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4578 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4580 * stime.c, stime.h: use SCM_P method.
4582 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4584 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4585 be given at least two arguments. Insist that lst's last element
4586 be a list, but don't make any requirements of its predecessors.
4588 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4590 * eval.c (scm_nconc2last): Revert last change; there seems to be
4591 other stuff going on here.
4593 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4595 * eval.c (scm_nconc2last): Make sure that each element of lst
4596 (which is a list of argument lists, except for the tail) is a
4597 proper list, i.e., finite and terminated by '().
4599 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4601 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4604 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4605 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4608 * vectors.c (scm_make_vector): Fill vectors with the undefined
4609 value, to help make Guile Scheme code more portable to other
4612 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4613 * symbols.h, tags.h: Doc fixes.
4615 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>

4619 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4621 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4622 want to subtract it from the modulus; we just want to leave it
4625 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4627 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to

4632 * throw.c (scm_catch_apply): Finished implementation of
4635 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4637 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4639 (scm_init_filesys): set "i/o-extensions" feature.
4642 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4644 * Makefile.in (root.o): Correct dependencies.
4646 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4648 * Makefile.in: Added dependency entry for root.o.
4650 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4651 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4653 * init.c (scm_start_stack): Set initial root continuation number
4656 * procs.c: New function: scm_thunk_p.
4658 * procs.h: Added declarations of scm_thunk_p.
4660 * root.c: Renamed `call-with-new-root' -->
4661 `call-with-dynamic-root'.
4662 (cwdr): Removed allocation of new root state. This should be done
4663 separately by use of scm_make_root.
4664 (scm_apply_with_dynamic_root): New function: Does what it
4665 sounds like. Needed when spawning threads.
4667 * root.h: Added member last_debug_frame to root state.
4668 Added #include "libguile/debug.h"
4670 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4671 arguments. The motivation is that code in root.c needs catch
4672 functionality, and we want to avoid code duplication.
4673 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4674 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4675 handlers that run without popping the stack into the dynwind
4678 * throw.h: Added prototypes for scm_catch_apply and
4681 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4683 * root.h (scm_root, scm_set_root): Decouple thread support details
4684 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4685 SCM_SET_THREAD_LOCAL_DATA.
4687 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4688 and tortoise scanning loop.
4690 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4692 * Makefile.in: Rebuild dependencies.
4694 * libguile.h: #include "libguile/print.h" before "smob.h", since
4695 the latter uses the print_state structure.
4697 * throw.c (scm_ithrow): Use the correct variable when checking to
4698 see if a given element of scm_dynwinds is a valid catch.
4700 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4701 structure, abort; don't just silently ignore the garbage.
4703 * _scm.h: #include "print.h" here, since it seems to be used just
4705 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4706 strports.c, unif.h: Don't #include "print.h".
4708 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4710 * feature.h (scm_loc_features): Removed external declaration.
4711 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4713 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4715 * feature.c (scm_init_feature): Added threads feature (needs to be
4716 initialized here, since features doesn't exist when
4717 scm_init_threads is called).
4719 * libguile.h: Added #include "libguile/../threads/threads.h".
4720 (This is a kludge to get thread support working. This should be
4723 * configure.in, acconfig.h: Added flags for thread support.
4725 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4728 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4729 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4732 * _scm.h: Added conditional #include "threads.h"
4734 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4735 SCM_THREADS_SWITCHING_CODE.
4737 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4738 allocate the basic dynamic root object.
4739 (scm_boot_guile): Added call to scm_init_root.
4741 * root.c, root.h: Added root smob.
4742 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4743 functions: Implements dynamic roots mostly according to spec in
4744 SCM manual. Main difference is that the second argument is a
4745 throw handler rather than an error "thunk".
4747 * root.h: Added declaration of scm_init_root.
4749 * root.c: Added #include "genio.h", #include "smob.h", #include
4750 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4752 (scm_init_root): Added #include "root.x".
4754 * throw.c: Added #include "stackchk.h"
4755 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4756 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4757 can be used in scm_call_with_new_root; Added reenabling of stack
4758 checking when catching a throw.
4760 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4762 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4764 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4765 element is not found, as per R4RS.
4767 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4769 * list.c: Doc fixes throughout.
4771 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4773 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4774 declare the char * to be const. Avoids a warning in rgx.c.
4776 * ports.h: spelling fix.
4778 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4781 * load.c (scm_sys_try_load_path): throw an error if file not found
4782 (like it says it in NEWS).
4784 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4786 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4787 PROPS slot to '(), not #f; it's an empty alist.
4789 * throw.h, throw.c: Use SCM_P instead of #if hair.
4791 Remove special support for uncaught throws; see throw.c for
4793 * throw.c (uncaught_throw): New function.
4794 (scm_ithrow): Call uncaught_throw if we don't find a throw
4795 target; don't mess with scm_bad_throw_vcell.
4796 (scm_bad_throw_vcell): Variable deleted.
4797 (scm_init_throw): Don't initialize it.
4799 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4802 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4804 * numbers.c (scm_istr2int): If the number is short (as most
4805 numbers are), just call scm_small_istr2int to deal with it.
4806 (scm_small_istr2int): New function, created by un-#ifdefing the
4807 non-bignum version of scm_istr2int and renaming it.
4809 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4811 * load.c (scm_sys_try_load): don't check whether value returned
4812 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4813 Change the Scheme name from %try-load to primitive-load.
4815 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4816 Can avoid passing a message, allowing it to be derived in the
4817 error handler (e.g., if we want to throw to the key both from
4820 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4822 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4823 references now have a new appearance which is more compact and
4824 also gives a clue about what the target of the reference is.
4825 By setting parameters in the print state, more fancy printing can
4826 be achieved. This is used by the (not yet commited) backtrace
4829 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4831 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4834 * print.c: Added #include "struct.h". Removed function
4837 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4838 scm_iprin1. Removed prototype for scm_prlist.
4840 * arbiters.c (prinarb),
4841 async.c (print_async),
4842 debug.c (prindebugobj, prinmemoized),
4843 eval.c (prinprom, prinmacro),
4844 filesys.c (scm_fd_print, scm_dir_print),
4846 mallocs.c (prinmalloc),
4847 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4848 smob.h (scm_smobfuns),
4849 srcprop.c (prinsrcprops),
4851 unif.c, unif.h (scm_raprin1, rapr1),
4852 variable.c (prin_var): Changed argument `int writing' to
4853 `scm_print_state *pstate'.
4855 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4856 that it will be called before scm_init_print.
4858 * print.c (scm_prin1): Print states are now allocated when calling
4859 scm_prin1 and then passed around to all printing functions as an
4860 argument. A cache `print_state_pool' enables reuse of print
4862 (scm_make_print_state): New function.
4863 (scm_iprin1): Adaption to print states.
4864 (scm_iprlist): An initial "hare and tortoise" scan brings down
4865 time complexity to O (depth * N). (Better time complexity will be
4866 achieved when the printing code is completely rewritten.)
4868 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4870 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4871 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4872 it gets done whether or not the cache variable has a value.
4874 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4876 Distinguish #f and ().
4877 * __scm.h: #undef SICP.
4878 * pairs.h (SCM_EOL): Delete this definition, equating it with
4880 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4881 the value it used to have. Doc fixes, too.
4883 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4885 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4886 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4887 Lord's implementation of structs, allowing for tail arrays as
4888 described in the manual. Also fixed some bugs. (Both the interface
4889 and the implementation should be improved.)
4891 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4893 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4894 People who whish to see the source can do `(print-enable 'source)'.
4895 Removed #ifdef DEBUG_EXTENSIONS.
4897 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4899 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4900 integer (assuming for now accepting an integer is a good thing).
4902 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4903 %S will be used instead for write'ing arguments.
4905 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4906 asserts. fix a few other asserts.
4907 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4908 scm_uniform_vector_ref, scm_array_set_x,
4909 scm_dimensions_to_unform_array): change args in
4910 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4911 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4912 scm_substring_fill_x): likewise.
4913 gsubr.c (scm_gsubr_apply): likewise.
4914 eval.c (SCM_APPLY): likewise.
4916 * eval.c (4 places): replace scm_everr with lgh_error or
4919 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4920 scm_memory_error): new procedures.
4921 scm_everr: deleted. can use scm_wta, dropping first two args.
4922 scm_error: convert NULL subr to SCM_BOOL_F.
4924 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4927 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4930 * error.c, error.h: new error keys: scm_arg_type_key,
4931 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4933 scm_wta: reimplement using lgh_error instead of scm_everr.
4935 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4937 * gdbint.c: scm_lread now has one more argument.
4939 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4940 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4941 loading source from non-file ports, which, e. g., happens when
4942 using the Emacs interface).
4944 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4947 * read.c: Added code for recording of positions of source code
4948 expressions; New functions: recsexpr, scm_lreadrecparen;
4949 _scm_make_srcprops --> scm_make_srcprops
4950 (scm_flush_ws): Removed updating of positions counters. This work
4951 is already done by scm_gen_getc
4953 * read.h: Added prototype for scm_lreadrecparen
4955 * print.c: Added #include "alist.h"
4957 * eval.c: Added #include "hash.h"
4959 * eq.c: Added #include "ramap.h"
4961 * options.c: Documentation fixes.
4963 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
4964 (scm_init_srcprop): Adjusted size of initial source-whash. Name
4965 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
4966 --> scm_make_srcprops
4968 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
4969 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
4970 function calls in the definition of the whash access macros.
4972 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
4974 * init.c (scm_boot_guile): Add level of indirection to
4975 scm_boot_guile_1() to ensure that stack base pointer is properly
4976 initialized. There was no guarantee that variable i was the
4977 highest/lowest variable on stack (i.e. the call frame of
4978 scm_boot_guile was not completely protected from gc).
4980 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
4982 * ports.h (scm_port_table): put back file_name, it will be used to
4983 support debugging. Undo related changes in fports.c, ioext.c,
4986 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4988 * ports.h (scm_port_table): remove file_name member for now, it seems
4990 * fports.c (scm_open_file): don't set file_name in PTAB.
4991 (prinfport): don't use file_name in PTAB.
4992 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
4993 * ports.c (scm_add_to_port_table): don't intialize file_name.
4994 (scm_port_file_name): remove for now.
4995 * gc.c (scm_gc_mark): don't mark PTAB file_name.
4997 * fports.h (scm_mkfile): prototype deleted.
4998 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
5000 * debug.c, unif.c: use scm_out_of_range instead of
5001 wta for range errors (ASSERT still needs work).
5003 * error.c, error.h (scm_out_of_range): new procedure.
5005 * error.c, error.h (scm_out_of_range_key): new key.
5007 * posix.c (scm_sync): #else was missing.
5009 * error.c, error.h: append _key to names scm_num_overflow and
5012 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
5013 of consing an empty list.
5014 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
5015 of macros, saves code and string space.
5016 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
5017 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
5018 lower case. Rename scm_syserror_m to scm_syserror_msg.
5019 error.h: prototypes for new procedures.
5021 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
5023 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
5025 * error.c, error.h: setup scm_num_overflow key.
5027 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
5028 Remove definition of SCM_OVSCM_FLOW.
5030 * fports.c (scm_open_file): use SCM_SYSERROR_M.
5032 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
5033 explicit message and args.
5035 * error.c, error.h, __scm.h: change system_error_sym to
5038 * error.c (system_error_sym): remove leading %% from the Scheme name
5041 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
5043 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5045 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
5046 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
5047 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
5048 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
5049 renamed. (These were introduced by unsupervised name
5052 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5054 * print.c: Added code for detection of circular references during
5055 printing. (init_ref_stack, grow_ref_stack): New functions. Added
5056 a hook for printing of closures (accessible via print options).
5057 This leads to a split of calls to scm_iprin1 into two classes:
5058 elementary print operations (e. g. the code which prints a smob)
5059 still use scm_iprin1 while top level calls (like scm_display) use
5060 scm_prin1. scm_prin1 begins by clearing the data structure used
5061 to record reference information.
5063 * print.h: Added declarations of scm_prin1 and scm_prlist.
5065 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
5067 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
5069 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
5071 * error.c (err_head): scm_iprin1 --> scm_prin1
5073 * debug.c: Adjusted header comment.
5077 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
5079 * strerror.c: Doc fix.
5081 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5083 * gdbint.c (gdb_read): Now possible to run during GC.
5084 (unmark_port, remark_port): New functions.
5086 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
5088 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
5089 of allocating a new string object. Also, increase size by
5090 the factor 2 instead of 1.5.
5092 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
5094 * __scm.h (SCM_P): Corrected to run under traditional C.
5096 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
5099 * async.c: Calls to scm_sysintern corrected.
5101 * async.h (scm_async_clock): Redundant declaration removed.
5103 * continuations.c (scm_dynthrow): Redundant declaration removed.
5105 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
5106 Definition typos corrected.
5108 * debug.h: Missing declarations of functions in debug.c added
5111 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
5112 Missing declarations to functions in eval.c added.
5114 * filesys.c: Possibly uninitialized variable rv.
5116 * gc.h (scm_object_addr, scm_unhash_name): Missing
5117 declarations of functions defined in gc.c added.
5119 * genio.c: Possible typos str_data -> wstr_data. ???
5121 * genio.c: Possibly unintended shadowing of local variable
5122 `int c' (gotos out of scope of inner `c'). ???
5124 * init.c: Uninitialized `SCM last' may be used.
5126 * ioext.h: (scm_sys_isatty_p): Typo.
5128 * list.h (scm_list_head): Missing prototype for function in
5131 * numbers.c (scm_two_doubles): Changed from extern to static
5132 (is used only within numbers.c).
5134 * numbers.h: Repeated declarations removed.
5136 * ports.h (scm_close_all_ports_except): Declaration for the
5137 function defined in ports.c added.
5139 * posix.h: Missing declarations added.
5141 * procs.h (scm_make_subr_opt): Missing declaration added.
5143 * socket.h (scm_sys_gethost): Missing declaration added.
5145 * socket.h: Redundant declarations removed (they are in fdsocket.h).
5147 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
5148 Missing declarations added.
5150 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
5152 * struct.c: Uninitialized variable `SCM answer' may be used.
5154 * unif.c (l2ra): Declaration prototype.
5156 * unif.c (scm_array_equal_p): Dummy definition removed (it is
5157 defined in ramap.c).
5159 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
5160 Redundant declarations removed (they are in ramap.h).
5162 * variable.h (scm_make_udvariable,
5163 scm_make_undefined_variable): Declaration corrected to
5164 correspond variable.c.
5166 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
5167 Missing declarations added.
5169 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5171 * Makefile.in (distclean): Don't forget to delete fd.h.
5173 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5175 * fd.h.in, tags.h: Trivial cleanups.
5177 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5178 marksweep.h just declared functions from gc.c.
5179 * gc.h, libguile.h: Don't #include "marksweep.h".
5180 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5181 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5182 dependencies updated.
5184 * libguile.h: Don't #include "files.h"; it's been deleted.
5186 * files.c (scm_sys_delete_file): Moved to filesys.c.
5187 File is now empty; deleted.
5189 * filesys.c: scm_sys_delete_file is now here. Remove
5190 #if's; they seem to rely on remnants of an old portability
5191 regimen. If the problems come up again, solve them properly,
5192 using autoconf. Specifically: Don't test M_SYSV, and #define
5193 remove to be unlink if it's #defined; don't use remove just
5194 because HAVE_STDC_HEADERS is #defined.
5195 * filesys.h: Add declarations for scm_sys_delete_file.
5196 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5197 files.o, files.h, files.c, and files.x.
5198 * init.c: Don't #include "files.h", and don't call scm_init_files.
5200 Use SCM_P instead of PROTO; the latter intrudes on the user's
5202 * params.h: Deleted; definition of SCM_P moved to...
5203 * __scm.h: ... here, where it replaces PROTO macro.
5204 * libguile.h, smob.h: Don't #include "params.h".
5205 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5206 smob.h: Fix prototypes accordingly.
5207 * Makefile.in: Update dependencies.
5208 (inner_h_files): Remove params.h.
5210 * gc.c: #include "gc.h"; every module should include its header,
5211 to let the compiler cross-check the declarations against the
5214 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5215 simpos.h: #include "libguile/__scm.h".
5217 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5219 * init.c: Don't forget to #include smob.h and init.h.
5220 * Makefile.in: Dependencies updated.
5222 * smob.h: Use PROTO instead of #if __STDC__.
5224 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5226 * __scm.h: Doc fixes.
5228 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5229 <angles>; this allows `make depends' to work properly.
5231 * libguile.h: #include smob.h and pairs.h before the others; they
5232 define typedefs used by other headers.
5234 C files should #include only the header files they need, not
5235 libguile.h (which #includes all the header files); the pointless
5236 recompilation was wasting my time.
5237 * Makefile.in (all .o dependency lists): Regenerated.
5238 * libguile.h: Don't try to get a definition for size_t here...
5239 * __scm.h: Do it here.
5240 * _scm.h: Since this is the internal libguile header, put things
5241 here that all (or a majority) of the libguile files will want.
5242 Don't #include <libguile.h> here; that generates dependencies on
5243 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5244 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5245 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5344 * stackchk.h: #include "libguile/debug.h",
5346 * print.h, read.h: #include "options.h", since everyone who uses
5347 either of these files will need that.
5349 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5350 anyone who uses this file will need them to define the smob
5351 printing functions. Also, get markers.h, since people will need
5352 to #define the mark functions.
5354 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5355 * ports.h: ... to here.
5357 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5358 don't rely on archaic C default type rules.
5360 * fports.h: #include "libguile/ports.h", since you need that in
5361 order to parse this.
5363 * genio.h: #include "libguile/print.h", because you need that to
5364 parse this; don't bother #including "ports.h", since print.h gets
5367 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5369 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5370 this; it's now a reference to an element of *scm_root.
5372 * debug.h: Don't #include "options.h"; the compiler won't be able
5373 to find that once the headers are installed; instead, #include
5374 "libguile/options.h".
5375 * gc.h: Same, with marksweep.h.
5376 * mbstrings.h: Same, with symbols.h.
5377 * scmhob.h: Same, with _scm.h.
5378 * smob.h: Same, with params.h.
5380 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5381 C files; there's no need for this, and it forces recompilations
5384 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5386 * error.c (scm_error): declare scm_error_callback.
5388 * error.h: prototype for scm_error_callback.
5390 * __scm.h: define lgh_error.
5391 (SCM_SYSERROR): redefine using lgh_error.
5393 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5395 * error.c (scm_error): new procedure.
5397 * error.h: prototype for scm_error.
5399 * Makefile.in (install): install scmconfig.h from the current
5400 directory, not $(srcdir).
5402 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5404 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5405 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5406 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
5407 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
5408 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,

5412 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5413 vports.h, weaks.h: #include "libguile/__scm.h", not
5414 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5415 dependencies are within libguile properly.
5417 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5419 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5420 when scmconfig.h doesn't exist.
5422 * load.c (scm_sys_try_load): Correct spelling.
5424 * feature.c (scm_loc_features): Make this static.
5426 * Makefile.in (libpath.h): Omit trailing slash from path. We
5427 shouldn't require it of users, so why put it here?
5429 Move code to initialize and search %load-path from ice-9 to C
5430 code, so we can use the load-path to find the ice-9 boot code;
5431 this makes it easier to run Guile without installing it. See
5432 corresponding changes in guile/Makefile.in.
5433 * feature.c: Move stuff concerned with the load path to load.c.
5434 (scm_compiled_library_path): Deleted.
5435 Don't #include libpath.h here.
5436 * feature.h: Don't mention scm_compiled_library_path.
5437 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5438 <sys/stat.h>, and <unistd.h> (if present).
5439 (R_OK): #define if the system hasn't deigned to.
5440 (scm_loc_load_path): New variable.
5441 (scm_init_load_path, scm_sys_search_load_path,
5442 scm_sys_try_load_path): New functions.
5443 (scm_init_load): Initialize scm_loc_load_path to point to the
5444 value cell of the Scheme %load-path variable.
5445 * load.h: Add declarations for scm_sys_search_load_path,
5446 scm_sys_try_load_path.
5447 * init.c: Call scm_init_load_path.
5448 * Makefile.in (feature.o, load.o): Dependencies updated.
5450 * load.c, load.h: Rewrite using PROTO macro.
5452 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5454 * gc.c (scm_cellp): New function: C predicate to determine if an
5455 SCM value can be regarded as a pointer to a cell on the heap.
5457 * gc.h: Added declaration of scm_cellp.
5459 * gdb_interface.h: New file: The GDB interface header from the GDB
5462 * gdbint.c: New file: GDB interface.
5464 * gdbint.h: New file: GDB interface.
5466 * libguile.h: Added #include <libguile/gdbint.h>.
5468 * init.c (scm_boot_guile): Added scm_init_gdbint.
5470 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5471 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5472 found if object files and source are kept separate).
5474 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5476 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5478 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5480 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5481 TK_SRC_DIR; they're not relevant any more.
5483 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5484 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5486 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5488 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5489 search path, so we can find the <libguile/MUMBLE.h> headers.
5491 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5493 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5494 implicit in the .c.o rule.
5495 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5498 Put the library path in a header file, instead of passing it on
5499 the command line in every compilation.
5500 * Makefile.in (libpath.h): New target.
5501 (feature.o): Depend on libpath.h.
5502 (clean): Delete libpath.h.
5503 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5504 * feature.c: ... #include "libpath.h" here.
5505 * .cvsignore: Ignore libpath.h.
5507 Don't install the unwashed masses of Guile header files in the
5508 main #include path; put most of them in a subdirectory called
5509 'libguile'. This avoids naming conflicts between Guile header
5510 files and system header files (of which there were a few).
5511 * Makefile.in (pkgincludedir): Deleted.
5512 (innerincludedir): New variable; this and $(includedir) are enough.
5513 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5514 (installed_h_files): Divide this up. Now this variable lists
5515 those header files which should go into $(includedir) (i.e. appear
5516 directly in the #include path), and ...
5517 (inner_h_files): ... this new variable says which files appear in
5518 a subdirectory, and are referred to as <libguile/mumble.h>.
5519 (h_files): List them both.
5520 (install): Create innerincludedir, not pkgincludedir. Put
5521 the installed_h_files and inner_h_files in their proper places.
5522 (uninstall): Corresponding changes.
5523 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5524 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5525 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5526 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5527 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5528 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5529 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5530 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5531 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5532 vports.h, weaks.h: Find __scm.h in its new location.
5533 * __scm.h: Find scmconfig.h and tags.h in their new locations
5534 (they're both "inner" files).
5536 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5538 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5540 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5542 * posix.c: Doc fixes.
5544 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5546 * socket.c: Don't include a prototype for inet_aton; just use a
5547 K&R style declaration, to avoid warnings but minimize the chance
5548 of conflicts with the system.
5550 On NextStep, <utime.h> doesn't define struct utime, unless we
5551 #define _POSIX_SOURCE before #including it.
5552 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5553 * acconfig.h: New comment text for above CPP symbol.
5554 * configure.in: Call it.
5555 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5557 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5559 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5560 testing for __EMX__.
5562 * posix.c: #include <libc.h>, if it exists.
5564 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5565 don't even know if the latter exists.
5567 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5568 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5569 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5571 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5573 (scm_init_posix): Use them when initializing the Scheme constants
5576 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5578 * Makefile.in (libdir, includedir, bindir): Use the
5579 autoconf-supplied values, instead of deriving them ourselves.
5580 (pkgincludedir, datadir, pkgdatadir): New variables.
5581 (install, uninstall): Put the header files in a special
5582 subdirectory, not in the main search path.
5584 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5585 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5587 * Makefile.in (IMPLPATH): Deleted; never used.
5589 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5590 on the Tcl/Tk source any more.
5591 (INCLUDE_CFLAGS): Remove references to the above.
5593 * Makefile.in (version.o): Corrected dependencies.
5595 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5597 * libguile.h: #include "version.h"
5599 * init.c (scm_boot_guile): Call scm_init_version.
5600 * gscm.c (gscm_run_scm): Call scm_init_version.
5602 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5603 GUILE_VERSION): AC_DEFINE these.
5604 (acconfig.h): #undef the above symbols.
5606 * Makefile.in (libobjs): Add version.o.
5607 (installed_h_files): Add version.h.
5608 (c_files): Add version.c.
5609 (gen_c_files): Add version.x.
5610 (version.o): New rule.
5611 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5612 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

5621 weaks.o): Add version.h to dependency lists.
5622 (markers.o): Remove duplicate rule.
5624 * version.h: New file.
5626 * version.c: New file.
5628 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5630 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5631 array; use it appropriately. Since GCC is quite happy to
5632 subscript functions, it never warned us about this; we should use
5633 -Wpointer-arith in the future. I guess we never tested
5636 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5638 * socket.c: Doc and copyright fixes.
5640 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5642 * debug.c: Fixed and improved gdb support.
5644 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5646 * socket.c: Added declaration of inet_aton to avoid compiler
5647 warning. (Hope this solution is correct.)
5649 * stime.c: Added declaration of ftime. (This is missing in
5652 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5654 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5656 * Makefile.in (c_files): add strerror.c.
5658 * strerror.c: new file from Emacs' sysdep.c.
5659 maybe configure should also check for sys_errlist.
5661 * configure.in (AC_REPLACE_FUNCS): add strerror.
5663 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5665 * debug.c (scm_init_debug): Added initialization for
5666 scm_evaluator_traps.
5668 * debug.h, debug.c: Various name changes.
5669 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5670 "debug-options-interface". See commentary in options.c.
5672 * options.h, options.c: Options now have documentation strings.
5673 Also added a long explanatory commentary.
5675 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5678 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5679 last_debug_info_frame is now updated in all cases.
5681 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5684 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5686 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5687 Added option STACK_CHECKING.
5689 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5691 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5693 * __scm.h: Removed symbols for debugging support.
5695 * acconfig.h: Added symbols for debugging support.
5697 * configure.in: Added user option for debugging support.
5698 --enable-debug will include the debugging code into libguile.a.
5700 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5701 scm_relocate_chunk_to_heap.
5703 * debug.c: New file: low-level debugging support. It also
5704 includes support for debugging with gdb. (The extensions to gdb
5705 are written by Per Bothner at Cygnus.)
5707 * debug.h: New file: low-level debugging support.
5709 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5710 argument pairs. Extensive modifications to the debugging
5711 evaluator. Added "SECTION:" commentaries to clarify what happens
5712 when, during double compilation. Renamed EVALIMP --> EVALIM.
5713 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5714 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5715 the beginning of the file. New procedure: scm_unmemocopy.
5716 Added some global state variables needed by the debugging
5717 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5718 check_entry, check_apply, check_exit, debug_options and
5719 evaluator_traps. New acro: undefine.
5721 * eval.h: Renamed EVAL --> XEVAL.
5723 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5724 --> scm_make_weak_key_hash_table.
5726 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5727 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5729 * libguile.h: Conditionally include debug.h
5731 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5732 scm_object_properties shouldn't return handle. `handle' now gets
5733 initialized in scm_set_object_properties_x. scm_object_properties
5734 doesn't any longer create an entry in scm_object_whash.
5736 * options.c: New file: handling of run time options.
5738 * options.h: New file: handling of run time options.
5740 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5742 * print.c: New procedure: scm_print_options
5744 * print.h: Defines for print options.
5746 * read.c: New procedure: scm_read_options
5748 * read.h: Defines for reader options.
5750 * root.h: Added scm_source_whash among scm_sys_protects.
5752 * srcprop.c: New file: source properties.
5754 * srcprop.h: New file: source properties.

5757 (Bug found by A. Green.)
5759 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5761 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5763 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5765 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5767 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5768 and should be called by the final client.
5770 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5772 * gc.h: Use the PROTO macro when declaring functions.
5773 * gc.c: Use the PROTO macro when declaring static functions.
5774 Remove the CPP hair around function definitions.
5776 * gc.c (scm_init_storage): Initialize scm_asyncs.
5778 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5779 preprocessor symbol; "__scm.h" is where it might get #defined.
5780 * __scm.h: Similar: #include <scmconfig.h> before testing
5783 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5785 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5787 * init.c (scm_boot_guile): Add init_func argument; call
5788 (*init_func) instead of calling scm_appinit; it's ucky to
5789 hard-code names for the user's procedures.
5790 * init.h (scm_boot_guile): Adjust declaration.
5792 * __scm.h (PROTO): New macro, for declaring functions with
5795 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5796 eliminate all the __STDC__ conditionals.
5797 (scm_boot_guile): Add declaration.
5798 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5799 Remove __STDC__ conditionals around function definitions; the
5800 declarations in init.h will provide the same information, more
5803 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5804 complain about it in the error message; the error message is
5805 adequate without that note, and there's nothing the user can do
5808 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5810 * Makefile.in (ancillary): Drop def.sed.
5812 * posix.c (scm_init_posix): Use numeric values, rather than
5813 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5814 F_OK. The symbols aren't available on some systems, and I'm
5815 pretty sure their values are fixed by common widespread practice.
5816 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5818 More functions unavailable on some systems.
5819 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5820 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5822 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5823 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5824 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5825 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5826 stub that signals an error as the #else.
5828 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
5830 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
5832 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
5834 * unif.c: include ramap.h.
5836 * read.c (endif): case_insensative_p renamed case_insensitive_p.
5838 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
5840 * ports.c: include sys/ioctl.h.
5842 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
5844 * configure.in: check for sys/ioctl.h.
5846 * ports.c: include <malloc.h> not "malloc.h".
5848 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5850 * fports.c: remove ttyname and tmpnam declarations.
5852 * posix.c: fewer ttyname declarations.
5854 * fports.c: include <string.h> not "string.h".
5856 * init.c, ioext.c: include string.h and unistd.h.
5858 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5860 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
5861 genio.c, simpos.c, vports.c: include string.h.
5863 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
5865 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
5867 (scm_addr_buffer_size): change type from scm_sizet to int.
5868 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
5869 from scm_sizet to int.
5871 * error.c: include unistd.h.
5873 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
5876 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
5878 * __scm.hd, def.sed: deleted.
5880 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
5882 Changes for NeXT, suggested by Robert Brown.
5883 * configure.in: Call AC_TYPE_MODE_T.
5884 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
5885 NeXT. Put header file list in alphabetical order.
5886 * configure, scmconfig.h.in: Regenerated.
5887 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
5889 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
5892 * acconfig.h: New file, providing documentation for the CPP
5893 symbols defined in configure.in
5894 * acconfig-1.5.h: Removed; superceded by the above.
5896 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
5898 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
5900 * fports.c (scm_open_file): don't return #f, throw error.
5902 * ioext.c (fileno): renamed from %fileno.
5903 (soft-fileno): deleted.
5905 * ports.c (scm_port_revealed): don't need to check for -1 from
5907 (scm_set_port_revealed_x): return unspecified, not #f.
5909 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
5911 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
5913 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
5915 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
5917 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5919 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5920 This is necessary on Ultrix, and doesn't hurt portability.
5922 * Makefile.in (dist-dir): New target, implementing a new dist system.
5923 (installed_h_files): Put in alphabetical order.
5924 Remove duplicate entries for markers.h and unif.h.
5925 (c_files): Remove duplicate entries for markers.c.
5926 (ancillary): Renamed from anillery; all uses changed. Remove
5927 PLUGIN; it's a directory, and needs special treatment in dist-dir.
5928 Remove all the ../doc/* files; doc/Makefile.in handles that.
5930 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5932 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5933 every if must have an else, or else the whole command has a
5934 non-zero exit code whenever the if's condition is false.
5936 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
5938 * posix.c: include string.h.
5940 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
5942 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
5945 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
5946 Remove leading % from scheme names.
5947 Do not return error values, call SCM_SYSERROR or similar.
5949 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
5951 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
5953 * struct.c (scm_init_struct): new file.
5955 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
5957 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
5958 (scm_list_head): added list-head for rapidly chopping argument
5959 lists off of longer lists (and similar).

5963 * objprop.c (scm_object_property): assq the cdr of the whash
5964 handle for obj, not the handle itself.
5966 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
5968 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
5969 weak hash tables last of all marking to avoid an obscure gc bug.
5970 WARNING: circular lists stored in a weak hash table will hose us.
5972 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
5974 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
5975 new functions similar to scm_substring_move_left_x and
5976 scm_substring_move_right_x.
5978 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
5980 * init.c (scm_boot_guile): prevent gc with scm_block_gc not

5985 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
5987 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
5989 * strports.c (scm_strprint_obj): convenience function. C for
5990 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
5992 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
5993 removed to a separate library
5995 * init.c (scm_boot_guile): copied from guile-tcl.c.
5996 Initialization specific to tcl interpreters removed.
5998 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
6000 * ports.c (scm_ports_prehistory): size malloced here doesn't
6001 matter so long as it is non-0 (got rid of "* 4").
6003 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
6005 * gscm.h: gscm_mkarray eliminated (presumably was not being used
6006 since its definition was bogus).
6008 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
6010 * mallocs.[ch]: back again (for rx at least).
6012 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
6014 * ports.c: removed functions relating to the mapping between ports
6015 and descriptors. (That stuff is unix-specific and should be collected
6016 in a separate library).
6018 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
6019 (Tom Mckay@avanticorp.com)
6021 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
6023 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
6024 handled correctly (SCM_FREEP was applied to them) -- test for
6025 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
6026 being overwritten with #f. (brown@grettir.bibliotech.com)
6028 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
6030 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs

6033 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
6035 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak

6045 Generalized assoc and hash-table functions.
6046 Factored pairs.c into multiple files.
6048 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
6050 * gscm.c (gscm_run_scm): got rid of objprop.
6052 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>

6058 NOTE: don't use a alist here.
6059 (scm_set_procedure_properties_x): fix type checking throughout this file.

6069 * vports.c (scm_make_soft_port): allocate a port table entry
6070 (possibly triggering gc) before setting the tag of the corresponding
6073 * pairs.c (scm_delq_x): never throw an error.
6075 * vectors.c (scm_make_vector): made the default vector fill argument
6076 into '() (much more useful than the previous value, "#unspecified")
6078 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
6080 * ports.c (scm_add_to_port_table): Added fields
6081 to port table entries: file_name, line_num, col.
6082 Update these in open_file, gen_getc and gen_ungetc.
6083 Added procedures to access those fields.
6085 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
6087 * procs.c (scm_make_subr_opt): new entry point for making

6101 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
6102 (scm_gc_stats): return an assoc of useful data. Replaces "room"
6103 and the stats reporting formerlly built into repl.

6117 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
6119 * feature.c (scm_compiled_library_path): moved here from repl.c.
6120 This file is for stuff relating specifically to Scheme libraries
6123 * eval.c (scm_m_define): don't give warning about redefinition, don't
6126 NOTE: this should throw a resumable exception with parameters --
6127 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
6129 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
6131 * error.c: scm_warn eliminated.

6143 between the call to procedurep and use.
6145 * error.c (scm_everr):
6147 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
6150 * strports.c: don't reveal the port's string to the caller
6151 because it changes size.
6153 (stputc stwrite): check/change the strings length with interrupts
6156 * objprop.c (scm_set_object_property_x &c): use the generic
6157 hashing functions and be threadsafe.
6159 * eval.c (scm_unmemocar): do this operation in a thread-safe way.
6160 (per suggestion jaffer@gnu.ai.mit.edu).
6162 * mbstrings.c (scm_multi_byte_string): guard against argument list
6165 * strings.c (scm_make_string): loop cleanup
6167 * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer

6181 functions. hash, hashq, hashv, hashx.
6183 * tags.h: made wvect an option bit of vector.

6187 * symbols.c: made the basic symbol table operations atomic.
6189 * root.c &c.: collected stack-specific global state.

6193 initialization to fix a race condition.
6195 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
6196 object, not in a global.
6197 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)

6214 * async.c: New support for interrupt handlers.
6216 Thu Feb 15 11:39:09 1996 Tom Lord <lord@beehive>
6218 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
6219 set the multi_byte flag correctly in symbols. This is wrong.
6220 intern_obbary_soft and msymbolize should take an extra parameter.
6221 Also, weird multibyte symbols don't print correctly.
6222 The weird symbol syntax is also a bit bogus (emacs doesn't quite
6225 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
6227 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means
6228 use the system symhash. == #t means create an uninterned symbol.
6230 Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>
6232 * strings.c (scm_make_shared_substring): build'em.
6233 It might better to keep a table of these and use one
6234 less cons-pair per shared-substring.
6236 Tue Feb 6 17:45:21 1996 Tom Lord <lord@beehive>
6238 * strings.c (scm_string_shared_substring): create shared

6301 segv. (kawai@sail.t.u-tokyo.ac.jp)
6304 * lvectors.c (scm_get_lvector_hook):
6305 In guile-ii, the lvector code was broken. It was fixed in guile-iii.
6306 It seems to me like if it is broken again in guile-iv...Here is a patch.

6311 * gscm.c (gscm_sys_default_verbosity):
6312 incorrectly declared for non-__STDC__
6313 (Tom_Mckay@avanticorp.com)
6315 * ports.c (scm_setfileno): Tweak the macro a bit
6316 to make it easier to port to systems that use
6317 more than a single structure field to hold a descriptor.
6319 * debug.c (change_mode): Avoid GNUCism "int foo[n];"
6320 Give a warning, not an error, for unrecognized modes.

6353 * numbers.c (scm_num_eq_p): Non-__STDC__ declaration of
6354 scm_num_eq_p() was scm_equal_p().

6373 Works around a compiler bug on some machines. (Tom_Mckay@avanticorp.com)
6375 * lvectors.c (scm_lvector_set_x): avoid VELTS (VELTS (...)[..]) which
6376 can turn into an obscure gc bug.
6378 * chars.c (scm_char_p): fixed PROC call.
6380 * gscm.h (gscm_vset): use scm_vector_set_x not (the missing)
6383 Tue Jan 23 13:29:40 1996 Tom Lord <lord@beehive>
6385 * elisp.c (new file): dynamic scoping and other bits for
6386 elisp. Don't use this yet unless you specificly want to
6387 hack on elisp emulation.
6389 * dynwind.c (scm_dowinds): When entering or leaving a dynamic
6390 scope created by scm_with_dynamic_bindings_operation_x, swap

6399 * eval.c (SCM_CEVAL): if the function position evaluates
6400 to a macro, process it accordingly. (Previously, macros were
6401 handled only if the function position was a symbol naming a
6402 variable bound to a macro).

6422 for multi-byte strings. Moved the string tag.
6424 * chars.h chars.c repl.c (many functions): made scm_upcase and

6438 * guile.c (gscm_is_gscm_type): New function. (Without this how will we
6439 know that it's safe to pass an object to gscm_get_type?)
