21 * script.c (scm_compile_shell_switches): Define
22 use-emacs-interface in the root module, so the repl code can see
23 it. See today's change to top-repl in ice-9/boot-9.scm.
25 * filesys.c (set_element, get_element): Make sure that `element'
26 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
27 Boekemeier and Jorgen "forcer" Schaefer.)
29 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
31 * chars.c (scm_charnames): In ASCII character name table, make
32 newlines print as #\newline by default, not #\nl.
34 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
35 alphabetical order. Oh thrills. But it helps me know how far
36 along in the compilation I am.
37 * Makefile.in: Regenerated.
39 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
41 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
42 #bytes(...) to #y(...), and syntax for short vectors from
43 #short(...) to #h(...). This may seem nutty, but, like the other
44 uniform vectors, byte vectors and short vectors want to have the
45 same print and read syntax (and, more basic, want to have read
46 syntax!). Changing the read syntax to use multiple characters
47 after the hash sign breaks with the conventions used in R5RS and
48 the conventions used for the other uniform vectors. It also
49 introduces complexity in the current reader, both on the C and
50 Scheme levels. (The Right solution is probably to change the
51 syntax and prototypes for uniform vectors entirely.)
53 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
55 Don't use local_fgets on sockets; ftell doesn't work on sockets.
56 (Thanks to Jorgen "forcer" Schaefer.)
57 * ports.h (SCM_NOFTELL): New flag.
58 * fports.c (local_fgets): If it's set, use the generic fgets.
59 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
61 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
63 * script.c (scm_compile_shell_switches): Add handling of -q switch
64 (inhibit loading of user init file).
65 (scm_shell_usage): Add usage text for -q switch.
66 (scm_compile_shell_switches): Always load user init file first if
69 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
71 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
72 and is now broken under NetBSD. I can't fathom what it's trying
73 to do, so I've replaced it with something that I do understand,
74 which seems to work, and which isn't broken on NetBSD. "Progress?
75 You Decide." (Thanks to Perry Metzger.)
77 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
78 signed/unsigned comparison.
80 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
82 Warning fixes from Greg Harvey:
83 * unif.c (scm_array_set_x): initializer for pos
84 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
85 * struct.c (scm_struct_ref, scm_struct_set_x): Added
86 initializers for field_type, since EGCS so desparately wants to
88 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
89 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
90 when GUILE_DEBUG is defined.
91 * dynwind.h (scm_wind_chain): Same.
92 * ports.h (scm_pt_size, scm_pt_member): Same.
93 * print.h (scm_current_pstate): Same.
94 * procs.h (scm_make_cclo): Same.
96 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
98 Handle short and long long uniform arrays properly. (Thanks to
100 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
101 raeql_1): Add cases for scm_tc7_svect (short vectors) and
102 scm_tc7_llvect (long long vectors).
104 Change the way libguile and boot-9.scm are timestamped, to try to
105 get rid of these spurious mismatch warnings. Now both
106 libguile/versiondat.h and ice-9/version.scm are generated directly
107 by the configuration process, rather than having version.scm
108 generated directly, and libguile/versiondat.h generated by the
109 Makefile, which is generated by configure. It seems that
110 sometimes the Makefile would change, but versiondat.h depends on
111 Makefile.in, not Makefile, so it wouldn't get rebuilt.
112 * Makefile.am (versiondat.h): Target removed; this is generated
113 directly by the configure script now.
114 (BUILT_SOURCES): Remove versiondat.h.
115 * versiondat.h.in: New file, transformed by the configure script
117 * Makefile.in: Regenerated.
119 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
120 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
121 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
122 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
123 if we want to use them in a header file some day, we can. (Thanks
126 * stime.c (scm_get_internal_real_time): Do the arithmetic using
127 SCM numbers, so we won't have rollover problems; the range of a
128 signed long in milliseconds is about 25 days. (Thanks to Karl
131 Don't redefine sleep and usleep; fix this problem now.
132 * coop.c (sleep, usleep): Remove declarations; we don't use or
133 redefine these any more.
134 (scm_thread_usleep, scm_thread_sleep): New functions which do the
135 job of usleep and sleep in a thread-friendly way. We can use
136 these in the rest of Guile. Define versions for systems both with
138 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
139 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
140 we're just using it, not redefining it, we can use a K&R style
142 (sleep): Declare this, too, if the system hasn't.
143 (scm_sleep, scm_usleep): Use scm_thread_sleep and
144 scm_uthread_sleep if they're available; otherwise, just call the
146 * scmconfig.h.in: Regenerated.
148 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
150 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
152 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
154 * threads.c: Doc fix.
156 The argument type of usleep varies from system to system,
157 as does the return type. We really shouldn't be redefining usleep
158 at all, but I don't have time to clean that up before the 1.3.
159 release. It's on the schedule for afterwards. (Thanks to Julian
161 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
163 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
164 * scmconfig.h: Regenerated.
166 * simpos.c (scm_software_type): Procedure deleted. This isn't the
167 right way to handle system variation. Autoconf's approach is the
169 * simpos.h (scm_software_type): Declaration deleted.
171 * script.c (scm_find_executable): Don't test if unix is #defined
172 here; first, NetBSD doesn't #define it, and second, it's the wrong
173 way to go about these things. (Thanks to Perry Metzger.)
174 (dld_find_executable): Delete this MSDOS support code. This isn't
175 the way we want to support this; it needs to be rethunk at a
178 * genio.c (scm_do_read_line): Don't just politely check that the
179 line was either non-empty or EOF. Abort if it's empty and not
182 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
184 * scmconfig.h.in: Regenerated.
186 * libguile.h: Don't omit the dynamic linking functions. (Thanks
189 * genio.c (scm_do_read_line): Count lines correctly when the file
190 doesn't end in a newline.
192 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
194 * genio.c (scm_do_read_line): Maintain the line count correctly.
195 (Thanks to Harvey J. Stein and Greg Harvey.)
197 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
200 * numbers.c (big2str): Protect t from garbage collection until
201 we're done. (Thanks to Gary Houston.)
203 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
205 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
207 * Makefile.in: Regenerated.
209 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
210 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
213 Do magic to mix reads and writes on stdio FILE-based ports.
214 (Thanks to Christian Lynbech.)
215 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
217 (pre_read, pre_write): New functions.
218 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
219 local_fputs): Call them.
220 (local_fflush): Mark the port as ready for reading and writing.
221 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
222 flags on new port objects. This might not be accurate --- who
223 knows what state the FILE * is in when we get it --- but it won't
224 do extraneous calls to fflush or fseek, so it's no worse than the
225 behavior before this change.
226 * ports.h: Add comment.
228 Centralize the creation of port objects based on stdio FILE * in
229 fports.c; don't just throw them together anywhere.
230 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
231 what the rest of Guile wants. Don't set the revealed count;
232 that's only appropriate for stdin, stdout, stderr.
233 (scm_standard_stream_to_port): This function does set the revealed
235 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
236 not scm_stdio_to_port.
237 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
238 * fports.c (scm_open_file): Same.
239 * posix.c (scm_pipe): Same.
240 * socket.c (scm_sock_fd_to_port): Same.
241 * ioext.c (scm_fdopen): Same.
242 (scm_freopen): Moved from here to...
243 * fports.c (scm_freopen): ... here. This is really something that
244 munges the internals of an fport, so it should go here.
245 * fports.h (scm_stdio_to_port): Adjust prototype.
246 (scm_standard_stream_to_port, scm_freopen): New protoypes.
247 * ioext.h (scm_freopen): Prototype removed.
249 * filesys.c (set_element, get_element): This can work on both pipe
250 and file ports, so use SCM_FPORTP to typecheck, instead of testing
253 * scmconfig.h.in: Regenerated.
255 Change the definition of the functions in scm_ptobfuns so that
256 they get passed the port object, not the port's stream.
257 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
258 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
259 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
260 Pass the port itself to the scm_ptobs function.
261 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
262 scm_generic_fgets): Same.
263 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
264 getc_void_port, fgets_void_port, close_void_port): Just change the
265 argument names; these functions don't really do anything.
266 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
267 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
268 port as an argument, and use SCM_STREAM to get the stdio FILE *.
269 Also, use prototyped definitions, and get rid of the extra
271 (scm_fptob, scm_pipob): We don't need casts here any more.
272 * strports.c (prinstpt): Use prototype declarations.
273 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
274 and use SCM_STREAM to get the string info. Also, use prototyped
275 definitions, and get rid of the extra declarations.
276 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
279 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
280 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
282 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
283 scm_fgets, for consistency.
284 (scm_fptop, scm_pipob): References updated.
286 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
288 Include the source location in error messages for scripts.
289 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
290 stack is still there when we catch the error.
291 * throw.c (handler_message): If we are handling an error with a
292 message, then put together the proper arguments and call
293 scm_display_error, instead of scm_display_error_message. That
294 displays source location, if it can find it.
296 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
298 * gc.c (scm_unprotect_object): Change this so that calls to
299 scm_protect_object and scm_unprotect_object nest properly.
300 (scm_protect_object): Doc fixes.
302 * strings.c (scm_string_set_x): Require the argument to be a
303 writable string, not a substring or a symbol.
304 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
305 (Thanks to John Redford and Charbel Jacquin.)
307 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
309 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
311 * eval.c (safe_setjmp): Remove this misunderstanding.
312 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
315 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
317 * libguile.h: Mark these as C declarations, for compilation by C++
320 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
321 __cplusplus clause. I seriously doubt this ever worked the way
322 the author seems to have intended.
324 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
326 Utterly needless cleanups to hopelessly messy code.
327 * ports.c: Doc fixes.
328 (scm_fflush): Moved to ...
329 * genio.c (scm_fflush): ... here, amongst all the other port
330 method invocation functions.
331 * genio.h, ports.h: The prototype moves too.
333 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
335 * backtrace.c (display_error_body): The current frame does not
336 always have a parent frame; consider a function called directly
337 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
340 * alloca.c (alloca): Undo yesterday's changes, and simply call
341 malloc directly for storage, and abort if we don't get what we
342 want. The situation is much simpler --- just call malloc. Emacs
343 has bizarre/evil requirements (signal handlers might malloc unless
344 you set this global flag, so you have to set the flag around all
345 calls to malloc) which we are certainly not going to conform to,
346 so we can do the simple and obvious thing.
348 * coop.c (coop_condition_variable_wait): Make this function
349 static. It's only useful internally --- you should never just
350 wait on a condition variable.
351 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
353 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
355 * unif.c (scm_array_set_x): Accept any kind of number as an
356 element for a uniform vector of doubles. This is more consistent
357 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
359 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
360 works; I can't conveniently test it myself. (Thanks to Dvid
361 Tillman for the bug report.)
365 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
366 from here, not from scm_compile_shell_switches (which is a pretty
367 dumb place to do it).
368 (scm_load_startup_files): New function.
369 (scm_ice_9_already_loaded): Variable moved to here from script.c.
370 * script.c (scm_compile_shell_switches): Don't load the startup
372 (scm_ice_9_already_loaded): Variable moved.
373 * init.c (scm_load_startup_files): Prototype for new function.
374 * gh_init.c (gh_enter): Doc fix.
376 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
378 Some anti-warning changes from Greg Harvey.
379 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
380 warnings when it doesn't understand our NORETURN declarations in
382 * posix.c (scm_mknod): Similar.
384 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
386 * posix.c (scm_getpwuid): If we can't find an entry, return our
387 own message, instead of using scm_syserror --- the getpwMUMBLE
388 functions don't set `errno' to anything interesting.
390 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
392 Get rid of warnings from the cooperative threading system.
393 * threads.h (scm_single_thread_p, scm_yield,
394 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
395 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
396 scm_wait_condition_variable, scm_signal_condition_variable): Add
397 prototypes for these Scheme-visible functions.
398 * coop-defs.h (coop_next_runnable_thread,
399 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
400 Prototypes for these here, even though they're from iselect.c.
401 (coop_condition_variable_wait, coop_join): Add prototypes.
402 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
403 scm_threads_free_condvar): Make these smob functions static.
404 * coop-threads.h (coop_init): Give this a real prototype.
405 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
406 (coop_next_runnable_thread): No need to provide prototype; it's in
409 * scmconfig.h.in: .detarenegeR
411 * iselect.c, threads.c: Doc fixes.
413 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
415 * Makefile.in: Regenerated with a patched automake, to get
416 dependency generation right when using EGCS.
418 * inet_aton.c (inet_aton): Add prototype, to remove compiler
419 warning. (Thanks to Robert Pluim.)
421 * inet_aton.c (inet_aton): Reassure the compiler that the
422 arguments to the <ctype.h> macros are all unsigned characters, not
425 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
427 Getting rid of more warnings...
428 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
429 today's change to ../configure.in.
430 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
431 * scmconfig.h.in: Regenertaded.de.,.__
432 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
433 (scm_localtime, scm_mktime): Use a const char * to manipulate the
436 * readline.c: Doc fix.
437 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
438 * readline.h (scm_filename_completion_function): Add prototype.
439 (scm_init_readline): Make this into a prototype.
441 * readline.c (scm_filename_completion_function): Use SCM_PROC to
442 declare this, instead of calling scm_make_subr manually.
444 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
446 * readline.h (scm_init_readline): Add prototype for this.
447 (scm_init_readline): Make this a real prototype.
449 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
451 Warning fixes from Maciej Stachowiak:
452 * backtrace.h (scm_display_application, scm_backtrace): Add
454 * debug.c (scm_m_start_stack): Make this function static.
455 * fluids.h (scm_fluid_p): Add prototype.
456 * procprop.c (scm_i_procedure_arity): Make this function static.
457 * regex-posix.c (scm_regexp_error_msg): Make this function static.
458 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
459 * root.h (scm_dynamic_root): Add external prototype.
460 * scmsigs.h (scm_usleep): Add external prototype.
461 * script.h (scm_init_script): Use prototype, not K&R decl.
462 * stacks.h (scm_stack_id): Add external prototype.
463 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
465 1998-09-30 Mark Galassi <rosalia@cygnus.com>
467 * gh.h: took out the definitions of vset and vref, since they are
468 replaced by the proper vector routines that correspond to the R4RS
471 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
473 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
474 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
475 third argument, a C expression that should result in a SCM value,
476 which is used to initialize the variable. Reimplemented
477 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
480 * version.h (scm_libguile_config_stamp): Add prototype.
481 (From Maciej Stachowiak.)
483 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
485 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
486 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
488 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
490 * print.c (scm_iprin1): Rather than having one i, and using it in
491 several places, declare a fresh i local to each block where it is
492 used, and give it a signedness appropriate to its use in each case.
495 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
498 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
499 signed/unsigned clashes.
501 * posix.h (scm_tmpnam): Added prototype.
503 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
504 scm_make_subclass_object): Add external prototypes.
506 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
507 comparison is okay here.
509 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
511 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
512 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
514 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
517 * load.c (swap_port): Make this function static.
519 * load.c (scm_search_path): Make max_path_len and max_ext_len
520 unsigned, since they're compared against string sizes.
522 * load.c (init_build_info): Make i unsigned.
524 * ioext.h (scm_read_line): Add prototype.
526 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
527 scm_hash_fn_remove_x): Make hash bucket index local variable k
528 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
529 accurately as possible.
531 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
532 comparisons, and range checking to make sure those casts are
535 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
536 signed/unsigned comparisons.
538 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
539 avoid signed/unsigned comparisons.
540 * smob.h (scm_numsmob): Change extern declaration to match.
542 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
543 avoid signed/unsigned comparisons.
544 * ports.h (scm_numptob): Change extern declaration to match.
545 (scm_current_load_port, scm_set_port_line_x,
546 scm_set_port_column_x): New prototypes.
548 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
549 test code, and it causes warnings.
551 * gh.h (gh_int2scmb, gh_uniform_vector_length,
552 gh_uniform_vector_ref): Added prototypes.
554 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
555 debugging support unconditionally. That's backtrace.c, stack.c,
556 debug.c, and srcprop.c.
557 (EXTRA_libguile_la_SOURCES): Omit those from here.
558 * Makefile.in: Regenerated.
560 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
562 * options.c (scm_options): Bugfix: Allow empty list of options!
564 * debug.c, debug.h (scm_single_step): Removed.
565 (scm_with_traps): New procedure. This procedure could easily be
566 written in Scheme but needs to be highly optimized.
568 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
570 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
571 Check SCM_TRAPS_P before trapping.
573 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
575 Changes to avoid signed/unsigned comparison warnings.
576 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
577 (scm_gc_sweep): Make n and j local to the blocks they're used in,
578 so they can have appropriate types for each application. Make i
579 signed. Use initializers in some spots. I'll probably pay for
581 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
582 (scm_must_realloc): Make nm unsigned.
583 (init_heap_seg): Make new_seg_index and n_new_objects signed.
584 (scm_init_storage): Use prototype-style definition, and make the
586 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
587 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
589 * filesys.c (scm_readlink): Make local vars rv and size ints, to
590 avoid signed/unsigned comparison warnings, and because the return
591 value of readlink may be -1. Don't bother casting the third
592 argument to readlink.
594 * filesys.c (scm_dirname, scm_basename): Move these to their own
595 page, at the end of the file.
596 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
598 * eval.h (scm_eval_options_interface): Add external prototype for this.
599 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
601 * eval.c (scm_lookupcar1): Make this static.
603 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
604 Make these prototype declarations, not K&R-style.
606 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
607 unsigned comparison warning.
609 * appinit.c: File removed. It had a single function in it, empty,
610 whose reason for existence is explained in no documentation or
611 comment. I think it's there as a default for some Tcl-style
612 initialization, but Tcl abandoned that approach a while ago.
613 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
614 (BUILT_SOURCES): Remove appinit.x.
615 * Makefile.in: Regenerated.
617 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
619 * Makefile.in: Regenerated using the last public version of
620 automake, not the hacked Cygnus version.
622 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
624 Remove Totoro kludge.
625 * Makefile.in, scmconfig.h.in: Regenerated.
626 * init.c, readline.c: Don't check if TOTORO is #defined.
628 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
630 * Makefile.am: Adjust for new thread configuration system.
631 (INCLUDES): Include the value of THREAD_CPPFLAGS.
632 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
634 (THREAD_LIBS): Definition deleted; automake will generate such
635 things automatically.
636 * Makefile.in: Regenerated.
638 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
640 Simplify smob and port marking; set the mark bit in the generic
641 marking code, and make marker routines only responsible for
642 turning up outgoing pointers.
643 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
644 before calling the marking function. Don't call the marking
645 function if it's zero.
646 * markers.c (scm_mark0): Just return #f. This function isn't
647 necessary at all now, but it's harmless to call it. We'll leave
648 it in so other folks' code doesn't croak at link time.
649 (scm_markcdr): Don't call SCM_SETGC8MARK.
650 * async.c (mark_async): Don't call SCM_SETGC8MARK.
651 * dynl.c (mark_dynl_obj): Same.
652 * root.c (mark_root): Same.
653 * srcprop.c (marksrcprops): Same.
654 * unif.c (markra): Same.
655 * variable.c (scm_markvar): Same.
656 * ports.c (scm_markstream): Same.
657 (void_port_ptob): Specify zero for our marking function.
658 * debug.c (debugobjsmob): Same.
659 * dynwind.c (guardsmob): Same.
660 * filesys.c (dir_smob): Same.
661 * fluids.c (fluid_smob): Same.
662 * fports.c (scm_fptob, scm_pipob): Same.
663 * mallocs.c (mallocsmob): Same.
664 * regex-posix.c (regex_t_smob): Same.
665 * smob.c (freecell, flob, bigob): Same.
666 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
667 * throw.c (jbsmob, lazy_catch_funs): Same.
669 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
671 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
672 scm_copy_tree on code in order not to let memoized code to leak
673 out. Thus, scm_copy_tree needs to copy vectors as well since
674 quasiquote can introduce evaluated code also inside vector
677 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
679 * eval.c (scm_copy_tree): Removed ability to copy vectors.
681 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
682 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
685 * unif.c: Say that ivect and uvect are of type signed and unsigned
686 long instead of int in commentary so that it correctly describes
689 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
691 * stime.c: Removed declaration of strptime. (It should be
692 declared by the system headers. If it turns out that some systems
693 don't, we'll handle that then.) (Thanks to Greg Troxel.)
695 * stime.h: Renamed TIMEH --> STIMEH
697 * backtrace.c (scm_display_error, scm_display_backtrace): In order
698 to increase portability, don't use structure assignment.
699 (Thanks to Nicolas Neuss.)
701 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
703 (finalize_fd_sets): Added empty statement after last case label.
704 (Thanks to Nicolas Neuss.)
706 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
709 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
711 * init.c, readline.c: OK, I won't have these readline.x bug
712 reports anymore. We've had them since April. The current reason
713 is a completely unintelligible failure of totoro.red-bean.com to
714 do the test for rl_getc_function in libreadline correctly. This
715 kludge overrides the test if we're on totoro so that the snapshot
716 generation process can work.
718 * readline.c: Define a strdup replacement if not existent on system.
720 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
722 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
723 This change makes scm_make_vector R5RS compatible. We cannot keep
724 the third argument since people want to be able to deduce the form
725 of the C function call only by looking at R5RS. (At the same time
726 we have removed some unnecessary complexity!)
728 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
729 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
730 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
731 argument in call to scm_make_vector.
733 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
735 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
736 This macro is useful in applications.
738 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
740 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
741 (scm_parse_path, scm_search_path): New Scheme level procedures.
743 * load.h (scm_internal_parse_path, scm_parse_path,
744 scm_search_path): Declared.
746 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
748 * filesys.c (dirname, basename): New procedures.
750 * init.c (scm_boot_guile_1): Removed condition around
753 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
754 new data type (guards) for representation of C level guards and
755 data on the wind chain.
756 (scm_internal_dynamic_wind): New function.
758 * dynwind.h: Declare scm_internal_dynamic_wind.
760 * root.h (scm_root_state): Added scm_cur_loadp.
762 * root.c (mark_root): Added comment about cur_loadp.
764 * load.c: #include "dynwind.h";
765 (scm_primitive_load): Use scm_inner_dynamic_wind to update
768 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
770 * ports.c (current-load-port): New procedure.
772 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
774 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
775 not a tty, return #f.
777 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
778 to Julian Satchell and Roland Kaufmann.)
780 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
781 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
783 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
785 * debug.h, debug.c (scm_start_stack): New function. Implements
786 the guts of old scm_m_start_stack.
788 * debug.c (scm_m_start_stack): Use scm_start_stack.
790 * init.c (scm_start_stack, scm_restart_stack): Renamed to
791 start_stack and restart_stack. (These have static scope.)
793 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
795 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
796 readline functions to come in release 2.3. (Thanks to Chet
798 (handle_errors): Use the above functions.
800 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
802 * readline.c: Improvements for readline support: Handle errors
803 better; Implement before-read-hook.
805 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
807 * init.c (scm_boot_guile_1), readline.c: Test for
808 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
809 assure that we have version >= 2.1.)
811 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
813 * readline.c (scm_readline): Defer interrupts while we're calling
816 * readline.c (scm_add_history): Bugfix: Do strdup before giving
817 away the string to add_history.
818 (completion_function): Do completion for readline. (Thanks to
820 (scm_filename_completion_function): New procedure: Filename
822 (current_input_getc): New function. Use this one instead of
823 standard getc from readline.
825 * throw.c, throw.h (scm_handle_by_throw): New function: This
826 handler throws errors to next handler on the dynwind chain.
828 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
830 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
833 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
835 * procprop.c (scm_i_procedure_arity): New function. Returns arity
837 (scm_procedure_properties): Modified to return arity together with
839 (scm_procedure_property): Added the read-only property `arity'.
840 (scm_set_procedure_property_x): It is an error to set the `arity'
843 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
844 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
846 * procprop.h (scm_sym_arity): New symbol.
848 * objects.c (scm_set_object_procedure_x): New procedure: Use this
849 to set the dispatch procedure of an operator or entity object.
851 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
852 Made procedure slots read-only.
854 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
855 scm_tcs_cons_gloc case in zero args switch; Fixed args
856 construction for operators in scm_tcs_cons_gloc case in two args
859 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
861 * fluids.c: Removed use of assert.h (in order to avoid
864 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
866 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
868 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
869 change makes the evaluator safer at the cost of evaluation speed.
870 It handles the case when the user has added a non-immediate
871 improper end of the application form, e.g., `(+ 0 . x)'.
872 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
873 minimize the extra cost as much as possible. The new code is
874 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
875 problem with structs planted directly in the code (e.g. by a
876 macro). This no longer causes segmentation fault. (Thanks to
879 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
880 arg `proc' in order to be able to throw errors; New argument
883 * Removed extra #include "debug.h"
885 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
887 * scmsigs.c: Declare usleep as returning void on some systems.
888 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
891 * coop.c (usleep): Return void on some systems.
893 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
895 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
897 * coop.c: Changed return type of usleep to int.
899 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
900 isn't found in the OS.
902 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
903 isn't enabled. (Thought that I had made this change ages ago...)
905 * iselect.c: Declare bzero if not defined by OS.
907 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
909 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
910 condition. (Thanks to John Tobey.)
912 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
913 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
916 * __scm.h: Start the long-term project of moving to POSIX threads.
917 Phase 1: Classification of all critical sections.
918 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
919 for A sections. (See comments in __scm.h for details.)
921 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
922 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
924 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
926 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
927 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
928 (libpath.h, versiondat.h): Replaced dependency on Makefile with
929 dependencies on $(srcdir)/Makefile.in
930 $(top_builddir)/config.status in order to avoid circularity.
932 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
933 from argc if argc was 0 initially.
935 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
936 in generation of libpath.h.
938 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
940 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
941 libguile from 2 to 3.
943 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
945 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
947 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
949 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
950 scm_set_port_column_x, scm_port_filename,
951 scm_set_port_filename_x): Removed optional arguments. Added
952 proper argument checking.
954 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
955 stack size in machine words.
957 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
958 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
959 to Ole Myren Röhne.)
961 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
963 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
964 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
966 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
969 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
970 procedure apply: Copy argument lists before pushing them unto the
971 environment so that the environment won't get mutated due to
972 manipulation of procedure arguments. This should perhaps be
973 regarded as a temporary solution until someone finds a more
974 efficient one. (Thanks to Maciej Stachowiak.)
976 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
978 * script.c (scm_compile_shell_switches): Use "guile" as default
979 zero arg if argc is NULL.
981 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
983 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
984 is zero. (Thanks to Dirk Herrmann.)
986 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
988 * ports.c (scm_add_to_port_table): First line is now line 0
989 (was 1). (Interface changed according to suggestion by Per
992 * backtrace.c (display_header): Add 1 to line and column numbers
993 when presenting them to the user.
995 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
996 from debug.c --> eval.c
998 * eval.h, eval.c (scm_eval_options_interface): New options
1000 (SCM_EVAL_STACK): New option: Size of newly created stacks,
1001 i.e. stacks for new threads.
1003 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
1005 * eval.c (unsafe_setjmp): Removed with #if 0.
1007 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
1010 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
1011 to avoid compiler warnings.
1013 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
1015 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
1017 * throw.c (handler_message): Print message on current error port
1018 instead of default error port. (Thanks to Maciej Stachowiak.)
1020 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
1022 * ports.c (scm_add_to_port_table): allocate in units of
1023 struct scm_port_table *, not struct scm_port_table.
1024 * posix.c (scm_close_pipe): remove the port from the port table
1026 Thanks to Rob Engle for both fixes.
1028 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1030 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
1031 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
1033 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1035 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
1037 * backtrace.c (display_error_body, display_backtrace_body),
1038 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
1039 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
1040 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
1041 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
1044 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
1045 don't receive the jmpbuf arg anylonger.
1046 (scm_catch): Don't accept a #f tag.
1047 (scm_throw): Check that key is a symbol.
1048 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
1050 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
1052 * async.c (async_pending): Removed declaration.
1054 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1056 * dynwind.c (scm_wind_chain): New debug function.
1058 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
1059 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
1060 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
1061 extra layer of functions around the body and handler of a thread.
1062 This extra layer makes sure that the handler is called in the
1063 dynamic context of the surround (= empty dynwind list), but under
1064 the *dynamic root* of the body. We can not use the dynamic root
1065 of the surround since that root belongs to another thread => stack
1066 is not handled correctly. It may seem ugly to use this extra
1067 layer, but the extra cost in terms of execution time is really
1068 negligible compared to the total amount of time required to create
1069 a thread, and it would reduce maintainability to duplicate the
1070 crucial and complicated steps performed by cwdr.
1072 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
1073 (SCM_ALLOW_INTS): Added thread switching code before interrupts
1074 get re-enabled. The important effect of this is that interrupts
1075 are blocked during thread switching so that thread data structures
1076 don't risk getting messed up by an unfortunate signal.
1077 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
1078 seems to do more aggressive optimization which actually move
1079 instructions around in these macros in a fatal way. Therefore:
1080 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
1081 just superstitious...)
1082 (SCM_TICK): Maybe do a context switch and take care of asyncs.
1083 This macro should be used instead of SCM_ASYNC_TICK since the
1084 latter doesn't do context switches any more.
1086 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
1087 instead of SCM_ASYNC_TICK.
1089 * coop.c, iselect.c: Since thread switches are now performed with
1090 interrupts masked, we can't use the old mechanism of delivering
1091 signals immediately when they arrive. Signals must instead be
1092 delivered when the asyncs run *after* the end of the critical
1093 section in scm_internal_select. But this also means after context
1094 switch so that the signal will be delivered to a different thread.
1095 To avoid this, I have changed the protocol of
1096 coop_wait_for_runnable_thread and friends so that they are allowed
1097 to return the original thread. So, if a signal arrives during
1098 scm_internal_select, we won't any longer be forced do a context
1099 switch, but can remain in the same thread and deliver the signal
1102 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
1103 scm_asyncs_pending and made it global.
1105 * iselect.c: Small fixes.
1107 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
1108 coop_condition_variable_init, coop_condition_variable_wait,
1109 coop_condition_variable_signal): Changed return type from `void'
1110 to `int'. This is to adhere closer to the pthreads interface.
1111 This, in turn, is part of an attempt to provide C versions of the
1112 mutex and condition variable primitives which can be part of a
1113 frontend to COOP or pthreads.
1115 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
1116 coop_condition_variable_destroy): New functions.
1118 * coop-threads.c (scm_wait_condition_variable): Use
1119 coop_condition_variable_wait_mutex.
1121 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
1122 Definitions moved to coop-defs.h.
1124 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
1125 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
1126 scm_cond_destroy): New C interface to mutecis and cond vars.
1128 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1130 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
1132 * iselect.c: Now several threads can wait on the same file
1133 descriptor. The behaviour is compatible with OS select: All
1134 threads waiting for the fd return with the same status.
1136 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1138 * coop-threads.c, threads.h (scm_spawn_thread): New function.
1139 Can spawn a thread from application C code.
1141 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1143 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
1144 gh_doubles2scm): New functions.
1146 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
1148 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
1149 commented-out version of gh_eval_str()
1151 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
1153 * socket.c (scm_bind): free soka after use.
1155 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
1157 * stime.c (tzvar): new variable.
1158 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
1159 avoid memory leaks when allocating.
1161 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
1163 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
1166 * gc.c, tags.h: Doc fixes.
1168 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1170 * eval.c (macro-eval!): Removed. This function was a design bug.
1171 It allowed memoized code to leak out to the scheme level. Most
1172 things that you could do with `macro-eval!' can be done with
1175 1997-12-20 Tim Pierce <twp@skepsis.com>
1177 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
1178 scm_fgets now depends on ftell(3) to know how many bytes were
1181 1997-12-15 Tim Pierce <twp@skepsis.com>
1183 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
1184 dealing with strings.
1186 1997-12-13 Tim Pierce <twp@skepsis.com>
1188 Make %read-line more suitable for implementing read-line efficiently.
1189 * ioext.c (scm_read_line): Strip the terminating newline from a
1190 string, and return a cons of the string and its terminator.
1192 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
1193 of the string that is read is stored in this memory location.
1194 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
1195 * genio.c, genio.h (scm_do_read_line): Update caller.
1196 * ports.h (scm_ptobfuns): Update typedef.
1197 * fports.c (scm_fptob, scm_pipob): Update struct.
1199 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1201 * filesys.c (set_element): Return file descriptor.
1202 (fill_select_type): Return the highest file descriptor.
1203 (scm_select): Tell select about the highest file descriptor. On
1204 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
1205 Therefore the extra overhead for calculating the maximum fd seems
1206 to be more than compensated. Is this correct? In any case,
1207 scm_internal_select will be much faster with this info.
1208 (scm_select, fill_select_type, set_element): Don't accept any kind
1209 of object in the file descriptor list or vector.
1211 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1213 * iselect.c (finalize_fd_sets): Bugfix.
1215 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1217 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1218 when using scm_internal_select (since we might switch to another
1221 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1223 * simpos.c (scm_system): always define: use sysmissing if not
1224 available. Check for HAVE_SYSTEM instead of _Windows (does
1225 Windows lack system or does it have an unusable one?).
1226 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1227 Let the argument be optional: if not supplied, call system(NULL).
1229 * ports.c (scm_close_port): relax the type check from OPPORTP to
1230 PORTP; closing a closed port is allowed.
1232 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1234 * fports.c (scm_fgets): Return if the last char in a chunk is
1235 newline. When fgets returns a string whose length is `size-1', it
1236 is ambiguous whether a whole line was retrieved, so we must check
1237 explicitly whether a line terminator is present.
1239 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1241 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
1242 before taking the CDR. (Thanks to Harald Meland.)
1244 * filesys.c (scm_stat): Slightly optimized.
1246 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
1248 * ports.c (scm_close_port): Make sure the port is open before
1251 * guile-snarf.in: Pass args through to gcc in a way that preserves
1252 whitespace boundaries. (Thanks to Greg Badros.)
1254 1997-12-02 Tim Pierce <twp@skepsis.com>
1256 * stacks.c (scm_frame_procedure): Reverse the logic in the return
1257 statement. (Thanks to Doug Evans for pointing this out.)
1259 1997-12-01 Tim Pierce <twp@skepsis.com>
1261 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
1263 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
1265 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
1266 errno macro expansion of this field name. (errno is a C
1267 preprocessor macro on some systems.)
1269 1997-11-29 Tim Pierce <twp@skepsis.com>
1271 * iselect.c: Doc fix.
1273 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
1275 * init.c (scm_start_stack): Removed initialization of
1276 scm_the_last_stack_var.
1278 * backtrace.h: Declare scm_the_last_stack_var.
1280 * backtrace.c: Define scm_the_last_stack_var.
1282 * root.c (mark_root): Don't mark the_last_stack_var.
1284 * root.h (scm_root_state): Removed the_last_stack_var.
1286 * throw.c: Added #include "fluids.h"
1287 (ss_handler): `the-last-stack' is now a fluid.
1289 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
1290 --> the_last_stack_fluid.
1292 * backtrace.c: Added #include "fluids.h"
1293 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
1294 (scm_backtrace): `the-last-stack' is now a fluid.
1296 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
1297 after scm_init_fluids.
1299 1997-11-28 Tim Pierce <twp@skepsis.com>
1301 * iselect.c: #ifdef USE_THREADS around thread-related includes.
1303 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
1304 DLSYM_ADDS_USCORE to decide whether to add an underscore.
1306 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1308 * iselect.c (coop_next_runnable_thread,
1309 coop_wait_for_runnable_thread): Disable interrupts so that no
1310 async is executed before a potential error_revive.
1311 (scm_internal_select): Disable interrupts during the parts of the
1312 code which manipulate the sleep queue and the file descriptors.
1314 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1316 * Makefile.am: Added iselect.c and iselect.h.
1318 * coop.c (coop_qinit): Initialize fields used by
1319 scm_internal_select.
1320 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1321 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1322 replacement in iselect.c.
1323 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1324 coop_join): If GUILE_ISELECT enabled, use
1325 coop_wait_for_runnable_thread instead of
1326 coop_next_runnable_thread.
1327 (usleep, sleep): New replacements for system functions if
1328 GUILE_ISELECT is enabled.
1330 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1332 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1334 * filesys.c: Added #include "iselect.h". Moved FD-macros to
1335 iselect.h. Implement Scheme level `select' using
1336 scm_internal_select. (See NEWS.)
1338 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1340 * init.c: Call scm_init_iselect.
1342 * iselect.h, iselect.c: New files. Implements
1343 scm_internal_select. (See NEWS.)
1345 1997-11-27 Tim Pierce <twp@skepsis.com>
1347 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1348 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1349 and scm_must_free, since ultimately the string returned will be copied
1350 by scm_makfrom0str anyway. Also, read any characters that may have
1351 been pushed onto the port with scm_ungetc.
1352 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1353 * ioext.c (scm_read_line): Free string after Guilifying it.
1354 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
1356 1997-11-26 Anthony Green <green@hoser.cygnus.com>
1358 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
1360 * gh.h: Safely wrap prototypes for c++ usage.
1362 1997-11-25 Mark Galassi <rosalia@cygnus.com>
1364 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
1365 gh_repl (argc, argv).
1367 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1369 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1370 and to invoke scm_shell().
1371 (gh_launch_pad): took out the loading of boot-9.scm from here,
1372 since it is probably best to let the user control that. In fact,
1373 gh_repl() now invokes scm_shell() which does that.
1375 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1377 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
1380 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
1382 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
1383 yesterday's underscore patch. (Thanks to Marius Vollmer for
1386 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
1388 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
1389 DLSYM_ADDS_USCORE is not defined.
1391 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
1393 * gh_data.c (gh_uniform_vector_length):
1394 (gh_uniform_vector_ref): started implementing the uniform types in
1397 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
1399 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1400 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1402 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1404 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1405 configure.in was changed).
1407 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
1409 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1410 * Makefile.in: Regenerated.
1412 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1414 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1415 OPORT is an `open' port, not an output port.
1417 * filesys.c (scm_close, set_element, get_element, scm_chown,
1418 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
1419 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
1420 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
1421 scm_close_port, scm_port_line, scm_set_port_line_x,
1422 scm_port_column, scm_set_port_column_x, scm_port_filename,
1423 scm_set_port_filename_x, scm_port_mode,
1424 scm_close_all_ports_except, scm_set_current_output_port,
1425 scm_set_current_error_port): Likewise
1426 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1427 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
1429 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
1430 * backtrace.c (display_backtrace_body): Likewise
1431 * fports (scm_setvbuf): Likewise
1432 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
1433 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
1434 scm_getpeername, scm_send, scm_sendto): Likewise
1435 * unif.c (scm_uniform_array_write): Likewise
1437 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
1439 Minor problems with substring-related tag changes.
1440 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1441 exactly what we want to leave in to detect substrings.
1442 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1443 * tags.h: Fix diagrams and comments describing the S tag bit;
1444 remove vestigial remarks about the D tag bit.
1445 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
1446 * strings.c: Formatting tweaks.
1448 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1449 variable first; then SCHEME_LOAD_PATH, with a warning message.
1450 (scm_parse_path): New function.
1451 * script.c: Doc fixes.
1453 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1455 Readline support, from Daniel Risacher.
1456 * readline.c, readline.h: New files.
1457 * init.c: #include "readline.h".
1458 (scm_boot_guile_1): Call scm_init_readline, if we have it.
1459 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1460 * Makefile.in: Regenerated.
1461 * scmconfig.h.in: Regenerated, after change to ../configure.
1463 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1465 * gh.h: gh_vector_set -> gh_vector_set_x
1467 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1469 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1470 with the ! -> _x mapping when going from Scheme to C.
1472 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1474 * gh.h (gh_reverse):
1482 (gh_assoc): added these gh_ functions implemented as macros.
1484 * gh_predicates.c (gh_null_p):
1485 (gh_string_equal_p): added these two missing predicates.
1487 * gh_list.c (gh_append):
1492 (gh_set_cdr_x): added these routines as I go through and try to
1493 complete the picture R4RS functions that should be mirrored in the
1496 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1498 * tags.h (scm_tc7_substring): Changed the comment and code to
1499 conform with the changes below. Folks! We have suddenly two new
1500 free tc7 codes!!! Jummy, jummy!
1502 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
1504 * Makefile.in: Rebuilt.
1505 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
1507 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
1508 * unif.c (scm_vector_set_length_x): Don't handle multibyte
1510 * tag.c (scm_utag_mb_string, scm_utag_mb_substring): Removed.
1511 (scm_tag): Don't handle multibyte strings.
1512 * read.c: Don't include mbstrings.h.
1513 (scm_lreadr): Don't handle multibyte ports.
1514 * kw.c: Don't include mbstrings.h.
1515 * init.c: Don't include mbstrings.h.
1516 (scm_boot_guile_1): Don't init mbstrings module.
1517 * hash.c (scm_hasher): Don't handle mbstrings.
1518 * gscm.c (gscm_run_scm): Don't init mbstrings module.
1519 * gc.c (scm_gc_mark): Don't handle mbstrings.
1520 (scm_gc_sweep): Likewise.
1521 * eval.c (SCM_CEVAL): Don't handle mbstrings.
1522 * eq.c (scm_equal_p): Use SCM_TYP7S, not SCM_TYP7SD.
1523 * tags.h (SCM_TYP7SD): Removed.
1524 (SCM_TYP7D): Removed.
1525 (scm_tc7_mb_string): Removed.
1526 (scm_tc7_mb_substring): Removed.
1527 * print.c (scm_iprin1): Handle char printing directly. Don't
1529 Don't include "mbstrings.h".
1530 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
1531 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
1533 Don't include "mbstrings.h".
1534 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
1535 (SCM_SYMBOL_SLOTS): Define as 4.
1536 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
1537 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
1538 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
1539 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
1540 struct.c, threads.c, throw.c, unif.c, variable.c: Use new
1541 ("gen"-less) I/O function names.
1542 * ports.c (scm_add_to_port_table): Don't set port's
1544 * ports.h (scm_port_representation_type): Removed.
1545 (scm_string_representation_type): Removed.

1547 (SCM_PORT_REPRESENTATION): Removed.
1548 (SCM_SET_PORT_REPRESENTATION): Removed.
1549 * genio.h: Use new function names.
1550 * genio.c: Don't include "extchrs.h".
1551 (scm_gen_putc, scm_gen_puts, scm_gen_write, scm_get_getc):
1553 (scm_putc, scm_puts, scm_lfwrite): No longer static.
1554 (scm_getc): No longer static; handle line and column changes.
1555 (scm_ungetc): Renamed from scm_gen_ungetc.
1556 (scm_do_read_line): Renamed from scm_gen_read_line.
1557 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
1558 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
1560 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1562 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1564 * gh_test_c.c (c_vector_test): some improvements on the vector
1567 * gh.h (gh_vector): this used to exist but do the wrong thing.
1568 Now it (almost) does the right thing, though it takes a list
1569 instead of the individual arguments. I need to see how it could
1571 (gh_list_to_vector): added this function as a macro. Corresponds
1572 to Scheme's (list->vector ...).
1573 (gh_vector_to_list): added this function as a macro. Corresponds
1574 to Scheme's (vector->list ...).
1576 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1577 gh_vector_ref, so that it resembles the Scheme routines more.
1578 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1579 resembles the Scheme routines more.
1580 (gh_make_vector): this used to be (stupidly) called gh_vector().
1581 This is the right name, since it does the same thing as the Scheme
1582 (make-vector ...) procedure.
1584 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1586 * ports.h: #include "libguile/print.h"
1588 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
1589 Some indentation fixes.
1591 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
1592 longer a user field; New field: class_flags.
1594 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
1596 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
1598 * gh_data.c (gh_bool2scm): new function which replaces
1599 gh_int2scmb(), which is now tagged as obsolete.
1601 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1603 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1604 macros should by convention not test for NIMPness.)
1605 (SCM_COERCE_OPORT): Adjust indentation.
1607 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1608 SCM_NIMP test before SCM_PRINT_STATE_P.
1610 * struct.c, struct.h, gc.c: Renamed:
1611 scm_struct_i_layout --> scm_vtable_index_layout
1612 scm_struct_i_vcell --> scm_vtable_index_vcell
1613 scm_struct_i_vtable --> scm_vtable_index_vtable
1614 scm_struct_i_printer --> scm_vtable_index_printer
1615 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1617 * struct.c (scm_print_struct): Use new printer slot; Default
1618 printing: Also output hex code of vtable so that type identity
1619 will be indicated as well.
1620 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1621 Removed struct_printer_var; Removed struct-vtable-offset;
1622 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1623 vtable-offset-user): New constants.
1625 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
1626 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
1627 If this slot contains a procedure, use that to print structures of
1628 the type represented by this vtable.
1630 * print.c (scm_iprin1): Don't print arguments of macro
1631 transformers. (They are always: exp env.); Bugfix: Unmemoize
1632 transformer source with correct environment.
1634 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1636 Streamlining of call-with-dynamic-root:
1638 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
1639 there is now only one catch.
1640 (cwdr_outer_body): Removed.
1641 (cwdr_handler): New function.
1642 (scm_internal_cwdr): New function to perform the function of cwdr
1643 but take args that are more useful to C code. Also, the handler
1644 is now invoked *outside* of the new dynamic root, like the docs
1645 say. We no longer have to catch absolutely all errors, the caller
1646 is responsible for using a handler that does not throw, if he
1648 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1649 * root.h (scm_internal_cwdr): New prototype.
1651 Even more but risky streamlining:
1653 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1654 allocation of the jumpbuf of a root continuation. The changes
1655 below are controlled by it. They are now deactivated.
1656 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1657 the JMPBUF of the scm_rootcont to NULL before returning.
1659 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1660 when they are non-NULL.
1661 (scm_gc_mark): Likewise, mark only when non-NULL.
1663 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1664 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1666 * gc.c (scm_done_malloc): New function.
1667 gc.h (scm_done_malloc): New prototype.
1669 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
1670 (struct scm_print_state) [revealed]: New field.
1671 (scm_print_state_vtable): Make visible to the outside world for
1672 type checking purposes.
1673 (scm_valid_oport_value_p): New prototype.
1675 * print.c (scm_valid_oport_value_p): New function to check whether
1676 a certain value is acceptable as a port argument.
1677 (scm_print_state_vtable): New variable.
1678 (scm_free_print_state): Set `revealed' field to false.
1679 (scm_iprin1): Call user supplied closure printer with
1680 scm_printer_apply. Print in the traditional way when there isn't
1681 one or when it returns #f.
1682 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1683 Accept a port/print-state pair in addition to just a port.
1684 (scm_prin1): Don't return the print_state to the pool when it has
1686 (scm_printer_apply): Set `revealed' field of print_state to true.
1687 (scm_init_print): Set scm_print_state_vtable.
1688 (print_state_fluid, print_state_fluid_num): Removed.
1690 * throw.h (scm_handle_by_proc_catching_all): New prototype
1691 throw.c (scm_handle_by_proc_catching_all): New function
1693 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1695 * Makefile.in: Regenerated with automake 1.2c.
1697 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1699 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1700 was looping endlessly.
1702 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1704 * strports.c (scm_eval_string): Don't close the port.
1706 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1707 former returns a nice normal integer. (Thanks to Daniel
1710 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1712 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1713 makefile variable as a build parameter called LIBS. The
1714 build-guile program will use this, for the time being.
1715 * Makefile.in: Regenerated.
1717 Thanks to Shiro Kawai:
1718 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1719 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1722 * Makefile.in: Regenerated with automake 1.2a.
1724 * script.c (scm_compile_shell_switches): If we hit the -c or --
1725 arguments, don't set the car of (command-line) to scm_usage_name,
1726 the prettified name of the guile executable; give it the full
1727 path, the way shells usually handle $0.
1729 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1731 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1732 Scheme-level name `array-map' and renamed `serial-array-map' to
1733 `serial-array-map!'.
1735 * backtrace.c: Introduced exception handlers which now enclose
1736 `display-error' and `display-backtrace' so that error reporting
1737 won't get into infinite loops if an error occurs during displaying
1738 of the error. This can very easily happen with user supplied
1739 print call-back routines.
1741 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1743 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1744 the names `serial-array-map' and `array-map' should be removed.)
1746 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1748 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1749 Added #include "objects.h"
1751 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1752 Add #include "feature.h".
1754 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1755 (modinclude_HEADERS): Added objects.h.
1757 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1758 This test is needed at many places in the code and should be
1759 abstracted. (Motivated by the need of this test in libguiletk.)
1761 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1762 (scm_eval_string), load.c (scm_primitive_load,
1763 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1764 Use SCM_EOF_OBJECT_P.
1766 * eval.c (scm_init_eval): Add feature `delay'.
1768 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1770 * scmhob.h: Removed.
1772 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1774 * list.h (SCM_LISTn): New macros. Make list creation in C code
1775 prettier. The idea comes from STk.
1777 * sequences.h, sequences.c, append.h, append.c: Removed. These
1778 files implemented non-R4RS operations which would encourage
1779 non-portable programming style and less easy-to-read code.
1781 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1784 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1785 sequences.h, #include append.h.
1787 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1790 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1792 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1794 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1796 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1798 * eval.c: Added #include "objects.h"
1800 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1803 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1804 adjacent smob numbers.
1806 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1808 * procprop.h: Added declaration of scm_i_inner_name.
1810 * gsubr.c: New global symbol scm_i_inner_name.
1812 * debug.c (scm_procedure_name): Try procedure property
1813 `inner-name' if `name' fails.
1815 * print.c (scm_iprin1): Use scm_macro_name.
1817 * eval.c (scm_m_define): Give names to macros as well; Only the
1818 first top-level definition gives a procedure/macro a name.
1819 Otherwise confusing names can turn up in backtraces.
1820 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1821 `name'; Give names to macros as well.
1823 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1824 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1827 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1829 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
1831 (prinmacro): Removed. The code has been moved/merged into print.c
1832 in order to decrease code redundancy. We want macros to print in
1833 a way equivalent to procedures, and it would be silly to duplicate
1834 the required code. (We don't want to maintain two places.)
1835 (macrosmob): Print field is now a NULL pointer.
1837 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1838 scm_macro_transformer): New prototypes.
1839 (scm_tc16_macro): Declared.
1841 * print.c (scm_iprin1): Added code for printing of macros. Macros
1842 are now printed in a way equivalent to procedures.
1844 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1846 * procs.h (scm_closure_p): Added declaration.
1848 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1850 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
1851 Shouldn't pass "heap" as the subr name.
1853 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1855 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
1856 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
1857 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1858 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1859 SCM_BOOL_T. Any non-false value is true.
1861 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1863 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1864 scm_gensym): Added prototypes.
1866 * symbols.c (scm_gensym): New function. This will speed up
1867 certain types of applications (such as macro systems) which
1868 generate lots of symbols.
1870 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1872 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
1874 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
1876 * unif.c (scm_shap2ra): tighten the checking of the array dimension
1877 specifier, since (2) or (2 . 3) would cause SEGV.
1878 (scm_transpose_array): more argument checking fixes.
1880 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1882 * Makefile.in: Regenerated.
1884 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1886 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
1888 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1890 * error.c, error.h (scm_error_callback): Removed (see NEWS).
1892 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
1894 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
1895 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
1898 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
1899 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1900 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
1901 scm_array_p, scm_array_rank, scm_array_dimensions,
1902 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
1903 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
1904 scm_array_prototype): Added case scm_tc7_wvect.
1906 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
1908 * errno.h: prototype for scm_strerror.
1909 * error.c (scm_strerror): new procedure.
1911 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1913 * list.c (scm_list_append_x): Allow non-pair as last argument.
1914 This is consistent with the R4RS append and is probably the
1915 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1917 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1919 * stime.h: prototype for scm_times.
1920 * stime.c (scm_times): new procedure.
1921 * ioext.c (scm_fseek): if the first argument is a file descriptor
1923 (scm_ftell): if the first argument is a file descriptor call lseek
1925 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
1926 * filesys.c (scm_chmod): if the first argument is a file descriptor,
1928 (scm_chown): if the first argument is a port or file descriptor,
1930 (scm_truncate_file): new procedure.
1931 Add DEFER/ALLOW INTS to a few other procedures.
1932 (scm_fsync): new procedure.
1933 (scm_open_fdes): new procedure.
1934 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
1936 (scm_fcntl): the first argument can now be a file descriptor. The
1937 third argument is now optional.
1939 * posix.c (scm_execl, scm_execlp): make the filename argument
1940 compulsory, since omitting it causes SEGV.
1941 (scm_sync): return unspecified instead of #f.
1942 (scm_execle): new procedure.
1943 (environ_list_to_c): new procedure.
1944 (scm_environ): use environ_list_to_c. disable interrupts.
1945 (scm_convert_exec_args): take pos and subr arguments and
1946 improve error checking.
1948 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1950 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1951 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1952 argument to SCM_ASSERT. Furthermore, the name of the function
1953 should be passed as first argument when signalling
1954 SCM_WNA. (Thanks to Thomas Morgan)
1956 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1957 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1958 dispatches on the number of actual args has a default case
1959 reporting an internal error. This is a vestige from a version
1960 that mallocated a SCM vector to hold the arguments. In the
1961 current version this check is too late: if it ever happens we will
1962 have already overstepped the bounds of the array.
1964 Also, the patch [...] adds a check for too many actual arguments."
1966 mdj: Removed check for "internal programming error".
1968 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1970 * gh_io.c (gh_write): New function.
1972 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
1973 throw.c (scm_internal_stack_catch): New sibling to the other catch
1974 functions. Code moved from gh_eval.c.
1975 throw.h: Added header.
1976 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
1977 scm_internal_stack_catch.
1979 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1981 * ioext.h: fix up prototypes.
1982 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
1983 Scheme name is now dup->fdes.
1984 (scm_dup_to_fdes): make the second argument optional and

2054 * ioext.c (scm_primitive_dup2): return the new file descriptor
2055 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
2057 (scm_fdopen): bug fix: don't try to make port unbuffered until its

2117 but that should be much less likely.

2137 (scm_setpwent): For setpwent.
2138 (scm_setegid): For setegid.

2162 DEBUG_EXTENSIONS isn't #defined.
2164 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>

2191 have to do this explicitly. Also, if regexp/basic is supplied, then
2192 turn off REG_EXTENDED.
2193 (scm_init_regex_posix): New regexp/basic symbol.
2194 (REG_BASIC): #define this if it is not already present.

2217 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
2219 (scm_init_regex_posix): Define constants for the REG_mumble flags;

2231 (init_build_info): New function.

2237 * root.c: Establish a reliable catch-all handler for the new root.
2238 After all the Scheme handler function might signal an error too,
2239 and we don't want to lose that.
2240 (cwdr_inner_body): Renamed from cwdr_body.
2241 (cwdr_outer_body): New function, to establish the user's handler,
2242 and pass control to cwdr_inner_body.
2243 (cwdr): Establish the reliable catch-all handler here, and pass
2244 control to cwdr_outer_body.
2245 (struct cwdr_body_data): New field, handler, to allow cwdr to pass

2250 * throw.h (scm_handle_by_message_noexit): New prototype.
2252 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
2253 across this. Only works on GCC. Otherwise, we hope for the best.
2254 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2255 the feeling that real thread systems will not need this...
2257 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2259 Try to detect when people are using one version of libguile and a

2271 primitive definitions under their Scheme names.
2273 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2274 1:2. Helps avoid confusion between installed and uninstalled libs.
2276 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2279 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2280 backslash from definition; this should be used like: GDB_INTERFACE;
2282 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2284 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
2285 new port unbuffered until its stream has been set.
2287 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2289 * ports.h: new prototype.

2299 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2301 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2302 argument plain char *.

2305 * tag.c (scm_tag): Remove unreachable statement.
2306 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2307 top of the word, it should be unsigned.
2309 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2310 is defined, to avoid warnings; it's only used in the
2311 conflict-checking code. Which might go away anyway.
2312 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2313 conditionals; put the label definition in an #if too, to stifle
2316 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2317 ChangeLog-threads in the distribution.
2318 * Makefile.in: Regenerated.

2328 * load.c (scm_init_load_path): Append $(datadir)/guile to
2329 %load-path, so modules do not have to be installed in Guile's
2330 current version directory.
2332 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2334 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2335 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2336 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always

2359 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2360 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2363 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2365 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2366 supplied. (Change from Tim Pierce.)
2368 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2370 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2371 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2372 default and not `()'. `#f' is the canonical non-value in Scheme,
2375 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2377 * struct.c (struct_printer): New variable that holds a handle on
2378 the Scheme variable *struct-printer*. This variable can be set by
2379 Scheme code to override the printing of structures.
2380 (scm_print_struct): If struct_printer is set, call it. If it is
2381 not set, or returns #f, print the structure in the old fashion.
2382 Include "eval.h" for scm_apply.
2384 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2386 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2387 scm_struct_i_n_words to get the number of fields, not
2388 -scm_struct_n_extra_words.
2390 On the route to fancier struct printing:
2391 * struct.c (scm_print_struct): New function to print a structure.
2392 Include "genio.h" to support it. This function doesn't do
2393 anything interesting right now, but I think it should be here
2395 * struct.h: Include "print.h" and add prototype for
2397 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2398 print structures ourself.
2400 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2402 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2403 before applying the handler in case it doesn't return.
2405 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>

2409 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2412 * posix.c (scm_uname): interpret only negative values as an error.
2413 Solaris normally returns a positive value.
2415 * script.c (scm_compile_shell_switches): if we are not going into
2416 an interactive repl, set scm_mask_ints to zero so that asyncs can
2419 * simpos.c (scm_system): don't ignore/unignore signals around
2422 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2425 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2426 done in boot-9.scm instead.
2428 * scmsigs.c, async.c: Major rewriting of signal handling code.
2429 (scm_sigaction): new procedure.
2430 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2432 (scm_raise): return unspecified, throw error on failure.
2434 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2436 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2437 feature, to help boot-9.scm decide whether to import the regex
2440 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2442 * eval.c: Include scmconfig.h at the beginning of the file so that
2443 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2446 * regex-posix.c: #include "_scm.h" before conditionally #including
2447 <regex.h>; the former defines HAVE_REGCOMP.
2449 * regex-posix.c: #include <regex.h> conditionally, so the file is
2450 CPP'able (for dependency scanning) even on systems that don't have
2453 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2455 Add new R4RS-compliant syntax for keywords.
2456 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2457 regardless of the setting of the `keywords' read option.
2458 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2459 can be re-read no matter what the setting of the `keywords' read
2462 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2464 Add support for POSIX regular expressions.
2466 * regex-posix.c, regex-posix.h: New files. (Some code
2467 is taken liberally from rx/rgx.c in the old Guile dist.)
2469 * init.c: Include regex-posix.h.
2470 (scm_boot_guile_1): Call scm_init_regex_posix.
2472 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2473 Add regex-posix.[ch] sources.
2474 * Makefile.in: Regenerated.
2476 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2477 to do this automatically? It didn't for me, bleh.)
2479 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2481 * fports.c (print_pipe_port): New function.
2482 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2483 latter doesn't even take the right arguments.
2485 * Makefile.am: Increment shared lib revision number. I think
2486 sometimes the uninstalled Guile finds the installed shared lib;
2487 Gord says doing this might help. As things turned out, I can't
2488 say whether it does.
2489 * Makefile.in: Regenerated.
2491 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2492 passing it as the closure argument to scm_boot_guile. (Bill
2495 * ports.c (print_void_port, putc_void_port, puts_void_port,
2496 write_void_port, flush_void_port, getc_void_port, close_void_port,
2497 noop0): Use ANSI prototypes instead of K&R declarations, so the
2498 initialization of void_port_ptob gets aggressively type-checked.
2499 Fix arguments of print_void_port and write_void_port. (Bill

2533 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2535 * script.c (scm_find_executable): Use prototype-style definition
2536 here; apparently it's not quite right to have const in a prototype
2537 and then use a K&R declaration. I wonder if stuff like this will
2538 go away if we compile with -Wrequire-prototypes, or whatever that
2539 is... (Bernard URBAN)
2541 * scmhob.h: New text from Bernard URBAN.
2543 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2545 * script.c: Don't #define const on hpux. Configure takes care of
2546 this. (Thanks to Larry Schwimmer.)
2548 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2549 decide whether to #include <unistd.h>, instead of listing a bunch
2550 of systems. Don't #include stdio twice. Removed dyked-out
2551 definition of scm_find_impl_file.
2553 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2555 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2556 library version info to 1:0.
2557 * Makefile.in: Regenerated.
2559 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

2563 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2564 throw.c: Update copyright years; these files have been worked on
2565 significantly in 1997, but only had copyright years for 1996.
2566 Also, change name of copyright holder on some from Mikael
2567 Djurfeldt to Free Software Foundation; he has signed papers
2568 assigning the changes to the FSF.
2570 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2571 reason not to give the user the option.
2573 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2574 Return #f on end-of-file when scanning table (i.e. when called
2575 with no arguments). Try to catch errors, when we can.
2576 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2578 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2579 external declarations. These are useful.
2581 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2583 * posix.c: don't include <sys/select.h> or define macros for
2584 select, since they were not used in this file.
2586 * filesys.c (scm_select): make the fifth parameter microseconds,
2587 not milliseconds. let the fourth parameter be either a real value
2588 or an integer or #f. The first, second and third arguments can
2589 now be vectors: the type of the corresponding return set will be
2591 (set_element, get_element): new static procedures.
2593 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2595 * strports.c (scm_eval_string): New function.
2596 (scm_eval_0str): Trivially re-implemented in terms of
2598 * strports.h (scm_eval_string): New extern decl.
2600 * net_db.c (h_errno): Add extern decl for this.
2602 * fports.c (local_pclose): New function.
2603 (scm_pipob): Use it in the initializer here.
2606 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2607 Use a meaningful error message when signalling an error. For
2608 this, scm_gethost must check h_errno rather than errno.
2610 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2612 * Makefile.in: Regenerated, using automake-1.1p.
2614 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2616 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2617 not SCM_UNSPECIFIED.
2619 * script.c (scm_compile_shell_switches): don't append (quit) if
2621 (scm_shell): call scm_exit_status and exit on the result of the
2624 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2626 Ensure that shared substrings are handled properly when passed to
2627 a system call or other foreign function. Many thanks to Tim
2629 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2630 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2631 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2632 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

2634 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
2635 (scm_display_error_message): use RO macros when strings may be RO.
2636 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
2637 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
2638 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

2642 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
2643 scm_strftime), vports.c (scm_make_soft_port): use
2644 SCM_COERCE_SUBSTR to make sure shared substrings are
2647 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2649 * error.c (scm_error): Add newline to error message.
2651 * init.c (scm_init_standard_ports): Doc fix.
2653 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2655 * dynl-shl.c: Completely replaced with new code from Bernard
2658 * script.c (scm_ice_9_already_loaded): New variable.
2659 (scm_compile_shell_switches): Use it.
2661 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2663 * filesys.c (scm_input_waiting_p): add missing third argument to
2666 * stime.c (scm_localtime): copy the result of localtime before
2667 calling gmtime in case they share a buffer.
2668 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2671 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2673 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2675 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2677 * Makefile.am (check-local): New target, which causes 'make check'
2678 to run gh_test_c and gh_test_repl, with some trivial input.
2679 * Makefile.in: Rgnrtd.
2681 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2683 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2686 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2688 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2689 sure how this was supposed to work.
2690 (scm_async_click): don't send SCM_TICK_SIGNAL.
2691 (scm_init_async): don't initialize %tick-thunk.
2693 * the following change doesn't affect the Scheme interface:
2694 gc-thunk is called at the end of garbage collection. however it's
2695 no longer implemented by pretending it's a signal.
2697 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2698 system async corresponding to scm_gc_thunk.
2699 * async.h: declare scm_gc_async.
2700 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2701 gc-thunk directly, instead of going through a signal handler.
2702 (scm_gc_async): new variable, points to the GC system-async.
2703 (scm_init_async): save the GC async as scm_gc_async instead
2704 of using system_signal_asyncs.
2705 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2707 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2709 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2710 Don't screw up if we're interrupted.
2711 * Makefile.in: Regeneradet.
2713 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2715 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2717 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2718 we're not using AM_INIT_GUILE_MODULE any more.
2719 * Makefile.in: Reneregated.
2721 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2723 Functions for finding variable bindings, grace à Tim Pierce.
2724 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2725 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2727 Get 'make dist' to work again.
2728 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2729 * Makefile.in: Regenerated, like a surry without a fringe on top.
2731 Changes for reduced Guile distribution: one configure script,
2733 * configure.in, configure: Removed.
2734 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2735 real configure script lives.
2736 * Makefile.in, scmconfig.h.in: Regenerated.
2738 * init.c: #include "script.h", to get prototype for script.c's
2741 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2743 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2744 scm_must_malloc, not raw malloc.
2746 * script.c (scm_compile_shell_switches): Dyke out debugging output
2749 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2751 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2753 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2754 system has them. Hope this is safe. Previously
2755 sys/timeb.h was included if HAVE_FTIME was defined or if
2756 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2757 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2759 * ioext.c (scm_setfileno): add missing third argument to
2760 scm_misc_error call.
2762 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2764 * eq.c (scm_equal_p): Correctly compare strings of different
2765 varieties. (Thanks to Tim Pierce.)
2767 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2769 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2770 #! block comment must occur on a line all by itself.
2772 Move most of the guts of shell command processing into libguile,
2773 so guile.c can be very small (and eventuallly auto-generated. (I
2774 mean, generated mechanically, not self-generated. Hmm.))
2775 * guile.c, script.c, script.h: New source files.
2776 * init.c (scm_boot_guile_1): Call scm_init_script.
2777 * libguile.h: #include "script.h".
2778 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2779 targets, for new executable.
2780 (libguile_la_SOURCES): Mention script.c.
2781 (modinclude_HEADERS): Add script.h.
2782 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2783 not dynamic linking is enabled. This is because we're generating
2784 executables now. Move CY_AC_WITH_THREADS call after those, so the
2785 values of cy_cv_threads_libs captures the libs chosen above.
2786 * Makefile.in, configure, aclocal.m4: Regenerated.
2788 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2789 We don't maintain this interface any more, and it just confuses
2792 * alloca.c: #include <scmconfig.h>, not <config.h>.
2793 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2794 it'll get included in disties.
2796 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2798 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2799 be distributed, because they confuse people.
2800 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2802 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2804 * configure.in: check for presence of gethostent (not present on
2805 OpenBSD by default).
2806 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2807 * configure, scmconfig.h.in: Regenerated.
2809 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2811 * backtrace.c (scm_backtrace): Split message string across
2812 newlines properly. GCC is more tolerant of this than other
2815 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
2817 Merge threads directory into libguile.
2818 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
2819 threads.h: New source files.
2820 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
2821 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2823 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2824 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2825 coop-threads.c.cygnus, coop-threads.h.cygnus.
2826 * configure.in: If we're using threads, include threads.o in
2828 * _scm.h, libguile.h: threads.h lives in this directory now.
2829 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2830 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2831 currently used, but brought along for information's sake.
2832 * ChangeLog-threads: log from old 'threads' directory.
2833 * Makefile.in, configure: Rebuilt.
2835 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2837 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2840 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2842 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2844 Merge GH interface library into libguile.
2845 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
2846 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2847 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2848 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2850 (EXTRA_libguile_la_SOURCES): ... here.
2851 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2852 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2853 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2854 New variables, describing how to build the gh test programs.
2855 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2856 build the test programs, and we probably should have been linking
2857 libguile.la against them all along, to support AIX shared libs.
2858 Add cflags for threads to CFLAGS; add libs for threads to new
2859 variable THREAD_LIBS, used in Makefile.am.
2860 * ChangeLog-gh: log from old `gh' subdirectory.
2861 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2863 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2865 * acconfig.h: Undo change of Apr 9; including the definition of
2866 PACKAGE in the guile headers conflicts with applications' own
2868 * scmconfig.h.in: Regenerated.
2870 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
2872 * filesys.c (scm_fcntl): New function from Roland McGrath.
2873 (scm_init_filesys): New symbols for use with fcntl.
2874 * filesys.h: Added prototype.
2876 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
2877 when PROC is receiving no arguments.
2879 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2881 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2882 have S_IFSOCK. This is the case under Ultrix.
2884 * posix.c (scm_status_exit_val, scm_status_exit_val,
2885 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2886 Ultrix versions of WIFSTOPPED, etc., which assume that their
2887 arguments are lvalues (hmm).
2889 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2891 * eval.c: Doc fixes.
2893 * throw.c: Doc fixes; rearranged.
2895 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
2897 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
2899 * acconfig.h: Added entry for PACKAGE.
2900 * scmconfig.h.in: Regenerated.
2902 Changes to work with automake-1.1n, which has better libtool support.
2903 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2904 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
2906 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
2908 * Makefile.in: Rebuild.
2910 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2912 * stime.c (scm_mktime): take an optional zone argument.
2913 (scm_localtime): check putenv return value.
2914 (scm_strftime, scm_strptime): moved from posix.c. move #include
2916 stime.h, posix.h: update prototypes.
2917 (bdtime2c, setzone, restorezone): new static procedures.
2918 (scm_mktime, scm_strftime): use them.
2919 (scm_strftime): don't call mktime before strftime. Use
2920 filltime for return value.
2921 (filltime): convert NULL zname to #f.
2922 (scm_strptime): return a count of characters consumed, not
2923 the remaining string.
2925 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2927 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
2928 (scm_mktime): likewise.
2930 Uncomment localtime and mktime.
2932 * configure.in: add AC_STRUCT_TIMEZONE.
2934 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2936 * stime.c (scm_init_stime): don't define ticks/sec.
2937 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2938 return value problem and is still portable.)
2940 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2942 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2943 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2944 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2945 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2946 cpp_err_symbols.c): Corresponding changes.
2947 * Makefile.in: Regenerated.
2949 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2951 * posix.c (scm_putenv): don't check HAVE_PUTENV.
2952 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
2953 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
2954 * putenv.c: new file, from sh-utils 1.12.
2956 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2957 since allocation isn't for Scheme objects.
2958 (scm_putenv): copy strings before placing in the environment.
2960 * stime.c (scm_current_time): throw an error if time returns -1,
2961 instead of returning #f.
2962 (scm_get_internal_real_time, scm_get_internal_real_time): use
2963 scm_long2num for return value instead of SCM_MAKINUM.
2965 * stime.h: prototypes updated.
2967 * stime.c (scm_time_in_msec): apparently unused, deleted.
2969 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2971 * configure.in: check for gettimeofday.
2973 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2974 which may be more usefully portable than a gettimeofday interface.
2976 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2978 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
2980 * Makefile.in: Regenerated.
2982 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2984 * stime.c (filltime): recovered static procedure.
2985 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
2988 * posix.h: add prototype for scm_close_pipe, remove prototypes for
2989 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2991 * posix.c (scm_mknod): split the mode argument into type and perms
2992 arguments, like the extra fields returned by stat.
2994 * fports.c (scm_pipob): set the close, free and print procedures.
2995 (scm_close_pipe): new procedure.
2997 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2998 define them in boot-9.scm
3000 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3002 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
3003 wan't defined. Don't include fd.h.
3005 * Previously fd.h was regenerated whenever configure was run,
3006 forcing a couple of files to be recompiled.
3008 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
3009 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
3010 Check for _fileno as well as _file.
3012 * ioext.c: don't fd.h.
3013 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
3016 * Change the stratigy for getting information about errno
3017 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
3018 generating lists of symbols during the build process, which will
3019 not always work, include comprehensive lists in the distribution.
3020 To help keep the lists up to date, the "check_signals" and
3021 "check_errnos" make targets can be used.
3023 * configure.in: don't check for a command to extract errno codes.
3024 * Makefile.am: update file lists, remove errnos.list and errnos.c
3025 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
3026 check_errnos targets.
3027 (CLEANFILES): remove errnos.c and errnos.list, add
3028 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
3029 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
3030 * errnos.default: deleted.

3033 * cpp_err_symbols, cpp_sig_symbols: new files.
3034 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
3035 * error.c (scm_init_error): #include cpp_err_symbols instead of
3037 * posix.c (scm_init_posix): don't intern signal symbols. #include
3040 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
3042 * strop.c (scm_i_index): allow the lower bound to be equal to the
3043 length of the string, so a null string doesn't always give an error.
3045 * posix.h: new prototypes.
3046 * posix.c (scm_status_exit_val, scm_status_term_sig,
3047 scm_status_stop_sig): new functions, as in scsh. They break down
3048 process status values as returned by waitpid.
3050 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
3052 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
3053 configure doesn't know about it.
3055 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3057 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
3059 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
3060 which defines C variables with global linkage.
3062 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3064 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
3067 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
3069 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
3070 has time to check why this doesn't work well with continuations.
3072 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
3074 * Fix shell syntax error; some shells won't tolerate
3075 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
3077 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3079 * posix.c (scm_uname): throw an error if uname fails instead
3082 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
3084 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
3087 * async.c (scm_ints_disabled): definition moved from error.c.
3089 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3091 * acconfig.h: Removed PACKAGE.
3093 * scmconfig.h.in: Regenerated.
3095 * snarf.h: g++ says it's non-portable not to specify the first
3096 argument in a varargs declaration. I introduced the first
3097 argument by using preprocessor conditionals.
3099 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
3101 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
3102 (scm_freopen): use RO string macros for filename and modes.
3103 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
3105 * posix.c (scm_getgrgid): simplify conversion of name to C string.
3106 (scm_mknod): use RO string macros for path.
3108 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
3109 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
3111 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
3112 use SCM_ROSTRINGP and SCM_ROCHARS.
3114 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3116 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
3119 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
3120 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
3121 support for byte vectors.
3123 * print.c (scm_iprin1): Limit number of vector elements printed
3124 according to pstate->length.
3126 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3128 * backtrace.c (scm_display_error_message): don't segv if message
3131 * error.h: prototype for scm_error_scm.
3133 * error.c (scm_error_scm): new procedure, reimplements scm-error
3134 in C and uses scm_error.
3136 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3138 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
3139 pointer to the Scheme variable read-hash-procedures and intern it
3140 in scm_init_read. Modify scm_read_hash_extend and
3141 scm_get_hash_procedure to use the pointer.
3143 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3145 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
3146 (SCM_KEYWORD_STYLE): defined.
3148 * read.c (scm_read_opts): add a keywords option. This isn't a
3149 boolean option, in case someone wants to add support for DSSSL
3151 Setup scm_keyword_prefix symbol.
3152 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
3154 I've left keyword support disabled by default, since it doesn't
3155 seem to break the module system and it gives R4RS standard behaviour.
3156 It can be reactivated with (read-set! keywords 'prefix).
3158 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3160 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
3161 before constructing arbiter.
3163 * eval.c (scm_m_define): Bugfix: Check that the object is a
3164 closure before setting the procedure property!
3166 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
3168 * ports.c: Removed `ungetc-char-ready?'.
3170 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
3172 * read.c (scm_init_read): intitialise scm_read_hash_procedures
3173 (idea from Mikael: make it a pair so scm_permanent object only
3175 (scm_read_hash_extend): don't call scm_permanent_object.
3176 (ideas from Mikael): if chr is already in the list, replace its
3177 procedure instead of appending it again. If proc is #f, remove
3179 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
3181 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
3183 * gdbint.c (gdb_read): update scm_lreadr usage.
3185 * load.h: update prototypes.
3187 * load.c (scm_primitive_load, scm_read_and_eval_x,
3188 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
3190 * read.h: add prototype for scm_read_hash_extend. Change args for
3193 * read.c (scm_read_hash_procedures): new variable.
3194 (scm_read_hash_extend): new procedure.
3195 (scm_get_hash_procedure): new procedure.
3196 (scm_lreadr): use scm_get_hash_procedure instead of an argument
3197 for extended # processing.
3198 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
3199 scm_read_token): remove case_i, sharp arguments. Change callers.
3201 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
3203 * read.h (SCM_N_READ_OPTIONS): increase to 3.
3204 (SCM_CASE_INSENSITIVE_P): define.
3206 * read.c: add case-insensitive option to scm_read_opts.
3207 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
3208 to determine whether to convert symbol case.
3209 (default_case_i): definition removed.
3210 * read.c (scm_read_token): if case_i, downcase ic before doing
3213 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3215 * configure.in: Added configuration option `guile-debug'.
3216 Configure with --enable-guile-debug if you want a bunch of extra
3217 functions used for debugging when developing Guile.
3219 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3221 * procs.c (make-cclo): New undocumented debugging procedure: Make
3222 compiled closure with internal procedure PROC and length LENGTH.
3223 Only compiled if GUILE_DEBUG is defined.
3225 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3227 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3229 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3231 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3232 with 3 or more args internally to the evaluator.
3234 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3236 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3237 with 3 or more args internally to the evaluator. This is mainly
3238 because we don't want to pass entry and exit points of the
3239 debug support twice, but it also seems to increase the speed of
3240 the evaluator for such calls (e. g. (+ 1 2 3)).
3242 * backtrace.c (scm_display_application): New procedure:
3243 display-application; Set fancy printing parameters individually
3244 for different types of display (backtrace, error, application).
3245 (These should of course be customizable!)
3247 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3248 clear the CHECK-flags.
3250 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3252 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3254 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3256 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3257 from pairs with a GLOC in the car.
3259 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3260 otherwise `symbol-hash' will behave badly.
3261 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3262 we get segmentation fault!
3264 * symbols.c: Added #include "weaks.h". New functions:
3265 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3266 moved to an extraneous library when we split libguile.)
3268 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3270 * filesys.c (scm_stat): stat now takes fport arguments too as
3271 documented in the manual.
3273 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3275 * debug.c (scm_single_step): Bugfix: Call continuation with
3276 scm_call_continuation instead of throwing to it.
3278 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3280 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3281 argument wasn't declared to be optional.
3283 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3285 * stime.c (scm_init_stime): Add feature "current-time".
3287 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3289 * throw.h: prototype for scm_exit_status.
3290 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3291 args to derive an exit status. Allows (quit) to work from a
3293 (scm_exit_status): new function.
3296 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3298 * eval.c (scm_deval): Removed some old code.
3299 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3301 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3304 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3307 * procs.c: Introduce the existent C function scm_thunk_p at the
3308 Scheme level as well.
3310 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3312 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3313 used from C to easily lookup the value of a symbol in the current
3316 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3318 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3319 scm_init_unif in this file. This will also fix a previous problem
3322 * configure.in: Added AM_MAINTAINER_MODE
3324 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3326 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3329 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3331 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3332 source files that are not always included in libguile but should
3333 have their dependencies calculated by automake. This variable is
3334 recognized by automake, no further magic is needed.
3335 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3336 to deal exclusively with *.lo files, as it seems. The *.o files
3337 are built automatically when the corresponding *.lo file gets
3340 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3342 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3345 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3347 * unif.c (scm_array_set_x): minor change to argument error checking.
3349 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3351 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3352 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3353 They should only be included in the library at configure.in's
3355 (libguile_la_LDADD): Include the appropriate .lo files here.
3356 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3357 so we know when to build them (and their .lo bretheren).
3358 * configure.in (LIBLOBJS): New substituted variable. We let
3359 configure decide which .o files to include in LIBOBJS, and then
3360 put the corresponding list of .lo files in LIBLOBJS. The latter
3361 is what we pass to libtool.
3362 * Makefile.in, configure: regenerated.
3364 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3366 * symbols.c (scm_sysintern0): New function. Contains the core of
3367 old scm_sysintern but doesn't take a second value argument.
3368 (scm_sysintern): Now uses scm_sysintern0.
3369 (scm_sysintern_no_module_lookup): Renamed to
3370 scm_sysintern0_no_module_lookup and doesn't take a second value
3371 argument any longer.
3373 * symbols.h (scm_sysintern0: Added declaration.
3375 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3376 scm_sysintern when interning option keys. Otherwise we risk
3377 destroying the values of already interned variables.
3379 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3380 scheme-level boolean (use SCM_NFALSEP).
3382 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3384 (scm_backtrace): New function. (C version of old function from
3385 boot-9.scm) Motivation: Make it possible to display backtraces
3386 without depending on boot-9.scm. (I'm uncertain if this
3387 motivation is good enough...)
3389 * root.h (scm_root_state): Add member the_last_stack_var.
3390 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3392 * root.c (mark_root): Mark scm_the_last_stack_var.
3394 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3397 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3399 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3400 1. mark_lazy_catch didn't mark the smob.
3401 2. Both functions above have standard variants:
3402 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3403 free_lazy_catch --> scm_free0.
3405 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3407 * throw.c (scm_internal_lazy_catch): New function.
3408 (scm_lazy_catch): Rewritten to use it.
3409 (scm_ithrow): Handle the new lazy catch representation.
3410 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3411 that doesn't have a jmpbuf is a lazy catch clause.
3412 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3413 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3414 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3416 (scm_init_throw): Register the new lazy-catch smob type.
3417 * throw.h (scm_internal_lazy_catch): decl for new function.
3419 * throw.c (scm_internal_catch): Doc fixes.
3421 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3422 configure.in. Including this might cause problems if applications
3423 that link against libguile include their own copies of alloca, but
3424 if they're using autoconf, they should be adding libguile to LIBS
3425 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3426 the copy in libguile, and things will be okay. (I think.)
3428 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3430 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3432 strop.h: move prototypes too.
3434 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3436 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3439 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3440 etc. I deleted them from filesys.c long ago, but didn't
3441 notice they were here too (although ineffective since
3442 sys/stat.h wasn't included).
3444 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3446 * eval.c: Don't define alloca in GCC case. gcc will automatically
3447 use __builtin_alloca if appropriate.
3449 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3451 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3452 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3453 that values of automatic variables are preserved. See comments
3454 for safe_setjmp for details.
3456 Change from Thomas Morgan:
3457 * variable.c: Include eq.h.
3458 (var_equal): New function.
3459 (variable_smob): Use var_equal as the discriminator for variables.
3461 * throw.c (s_throw): Remove extraneous declaration.
3463 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3464 * eval.c: Add necessary CPP cruft to support that.
3465 * configure, Makefile.in, scmconfig.h.in: regenerated.
3467 Change from Thomas Morgan:
3468 * procprop.c (scm_procedure_properties): Convert the Scheme
3469 boolean returned by scm_procedure_p into a C boolean before using
3470 it as a condition for SCM_ASSERT.
3471 (scm_procedure_property): Likewise.
3473 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3474 indications of Unixness.
3477 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3479 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3481 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3483 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3484 "unknown # object" error messages.
3486 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3487 (scm_i_index) and declare it static. Add a 'direction' argument
3488 to indicate what way the search should go.
3489 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3491 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3492 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3494 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3496 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3498 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3499 to avoid clash with various scsh forks.
3501 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3503 The following two changes (ramap.c, throw.c) are motivated by the
3504 apparent unportability of forward declarations of static arrays of
3505 the form `static foo bar[];'.
3507 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3508 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3510 * throw.c (scm_throw): Moved above scm_ithrow.
3512 * options.h: Removed the extern declarations of scm_yes_sym and
3513 scm_no_sym since these are static.
3515 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3517 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3519 * Makefile.am: remove AWK=@AWK@.
3520 Add a rule for generating errnos.list.
3521 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3523 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3524 don't extract errnos, just set a variable (avoids the
3525 need to recompile error.c just because configure is run.)
3527 * unif.h: update prototypes.
3528 * unif.c (scm_uniform_array_read,write): change the offset and
3529 length arguments to start and end, for consistency.
3531 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3533 * ioext.h: update prototypes.
3534 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3535 scm_read_line_x, it's a more general procedure using an
3536 interface from scsh. read-line and read-line! are now defined
3538 Note that the new read-line trims the terminator
3539 by default, previously it was appended to the returned string. An
3540 optional argument specifies how to process the terminator (scsh
3541 compatible). For the old behaviour: (read-line port 'concat).
3542 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3543 returns a pair, but is converted to multiple values if the scsh
3546 socket.h: update prototypes.
3547 * socket.c (scm_recvfrom): for consistency with other procedures,
3548 take start and end as separate optional arguments.
3549 (scm_recv, scm_recvfrom): don't allow the second argument
3550 to be a size, only a buffer. Change the scheme names to
3551 recv! and recvfrom!. Don't return the buffer.
3553 * ioext.h, posix.h: move prototypes too.
3554 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3555 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3556 "read.h" and "unif.h".
3557 * ioext.c: include "chars.h"
3559 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3561 * dynl.c: The dynamic linking and module registration functions
3562 are now defined even when dynamic linking is not available for the
3563 host system. Some of their functionality can be done without
3564 dynamic linking; when it's really needed, they throw errors.
3566 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3568 * configure.in: Only define DYNAMIC_LINKING when one of the system
3569 dependent functions is detected.
3570 * dynl.c (scm_dynamic_func): New function to get the address of a
3571 function in a dynamic object.
3572 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3573 produced by scm_dynamic_func as the thing to call.
3575 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3577 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3578 (scm_register_module_xxx, scm_registered_modules,
3579 scm_clear_registered_modules): New functions.
3581 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3583 * symbols.c (scm_sysintern): Renamed to
3584 scm_sysintern_no_module_lookup.
3585 (scm_sysintern): New function to take the place of the old
3586 scm_sysintern. It uses the current toplevel lookup closure to give
3587 the symbol its value. This is a temporary hack to put packages
3588 like gtcltk into their own module.
3589 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3590 us whether `scm_top_level_lookup_closure_var' has been initialized
3592 * eval.c (scm_init_eval): Set it.
3594 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3596 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3597 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3599 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3601 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3602 scm_sys_dup): deleted: FD capability will be added to other
3604 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3605 scm_fd_free, fd_smob, scm_intern_fd.
3606 (scm_open): renamed from scm_sys_open. Return a port instead of
3607 an FD object. Make the mode argument optional.
3608 (scm_sys_create): deleted, it's just a special case of open.
3609 (scm_init_filesys): move interning of constants O_CREAT etc.,
3610 here (were previously using SCM_CONST_LONG macro).
3611 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3613 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3614 include "fports.h" and <stdio.h>
3615 (scm_stat, scm_select): don't support FD objects.
3617 * error.h: adjust scm_syserror_msg prototype.
3618 * error.c (scm_syserror_msg): take an extra argument for errno.
3619 Using the global value didn't always work, since it could be
3620 reset by procedure calls in the message or args arguments.
3622 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3623 I don't understand why the check was there (and what about the
3626 * strop.c (scm_string_copy): allow shared substrings to be copied.
3628 * unif.h: corresponding change to prototypes.
3629 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3630 recognize two new optional arguments: offset and length. Allow
3631 the port argument to be an integer (file descriptor, for scsh).
3632 Include <unistd.h> for "read" prototype.
3634 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3636 * socket.c: don't include filesys.h.
3638 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3640 * Makefile.am: add AWK=@AWK@ (?)
3642 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3644 Add a rule to generate errnos.c from errnos.
3645 * error.c (scm_init_error): include errnos.c.
3646 * errnos_cnvt.awk: new file, converts the list of errno codes to
3648 * errnos_get.c: new file.
3649 * errnos.default: new file, contains errnos to try if they can't
3650 be extracted from errno.h.
3651 * configure.in: if using GCC, try and extract errno codes from
3655 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3657 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3658 * Makefile.am: Made libguile into a libtool library.
3659 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3660 Set libtool_libs to indicate that libguile is a libtool library.
3661 See guile/ChangeLog for details.
3662 * .cvsignore: ignore "*.lo", the libtool library objects.
3664 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3666 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3667 use htons in getservbyport argument.
3669 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3671 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3672 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3675 * objprop.c (scm_object_property): No need to take the CDR of the
3676 value returned by scm_object_properties, since Aug 20 change.
3678 * configure.in: When checking for struct linger, #include
3679 <sys/types.h> as well as <sys/socket.h>. I've never known
3680 <sys/types.h> to cause any portability problems, and Solaris's
3681 <sys/socket.h> needs it.
3682 * configure: Rebuilt.
3684 I think the Sun compiler has chosen a perverse way to interpret
3685 ANSI declarations combined with K&R definitions. We'll
3686 appease it a little bit. But when it invades France, we fight.
3687 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3688 * print.h (scm_iprlist): Here too.
3689 * numbers.c (scm_divbigdig): Change definition to match
3690 declaration in numbers.h.
3691 * unif.c (scm_makflo): Change definition to match declaration in
3694 * init.c (scm_boot_guile): Don't return the value of
3695 scm_boot_guile_1. This function doesn't return a value;
3696 scm_boot_guile_1 doesn't return a value (or return at all).
3698 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3701 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3702 compile. I have a feeling this function is a bad idea anyway ---
3703 one should always test for features, not systems.
3705 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3706 semicolons. Only pure luck kept this from being noticed earlier.
3708 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3710 * socket.c (scm_recvfrom): Added missing semicolon.
3712 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3714 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3715 the buffer and start and end positions for scsh networking
3718 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3720 * configure.in: Revert previous change to this file; the problem
3721 is due to transient automake weirdness.
3722 * configure: Rebuilt.
3724 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3725 PLUGIN/guile.libs. configure generates the latter from the former.
3726 * Makefile.in: Rebuilt.
3728 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3729 need this if we install scripts, like guile-snarf.
3730 * configure: Rebuilt.
3732 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3734 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3736 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3738 * socket.c (scm_addr_vector): fix faulty scm_listify.
3740 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3742 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3743 style block comment is no longer considered an error.
3745 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3747 * PLUGIN/guile.libs.in: New file.
3748 * PLUGIN/guile.libs: Removed from repository.
3749 * configure.in: Create PLUGIN/guile.libs from
3750 PLUGIN/guile.libs.in. This is for including additonal libraries
3751 needed for dynamic linking.
3752 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3753 instead of PLUGIN/guile.libs.
3755 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3757 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3759 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3760 occurrences of the given element from the list, not just the
3761 first. This is how the Emacs Lisp functions behave, how the
3762 analogous Common Lisp functions behave, and (I believe) how the
3763 older Maclisp functions worked. I realize that this change may
3764 break code, but it seemed better to break it before the Guile
3767 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3768 Their prototypes were already present in gc.h, but they weren't
3770 (scm_init_storage): Initialize scm_protects.
3771 * root.c (scm_protects): New element of scm_sys_protects.
3773 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3775 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3777 * libguile.h: Added #include "libguile/net_db.h".
3779 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3780 30 change. That file is only meant for communication between the
3781 configuration process and load.c. If code linked against libguile
3782 wants to get at the paths mentioned in libpath.h, it can call
3783 functions declared in load.h.
3785 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3787 * libguile.h: Removed #include "libguile/fdsocket.h"
3789 * net_db.c: Added #include <sys/socket.h>.
3791 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3793 * filesys.c (scm_input_waiting_p): use select in preference to
3794 FIONREAD, since the latter doesn't detect EOF.
3795 Throw error if neither select nor FIONREAD available.
3797 * socket.c (scm_connect): take a port, not a fd object.
3798 (scm_fill_sockaddr): throw an error if fam is not recognised.
3799 (scm_bind): use scm_fill_sockaddr.
3800 (scm_listen): take a port, not a fd object.
3801 (scm_accept): take and return a port. return #f in the car if
3802 address can't be got
3803 (scm_sock_fd_to_port): new procedure.
3804 (scm_socket): use scm_sock_fd_to_port.
3805 (scm_addr_vector): throw error if unrecognised address type.
3806 take an extra argument with the calling procedure name.
3807 (scm_getsockname): take a port. return #f if address can't be got.
3808 (scm_getpeername): take a port. return #f if address can't be got.
3809 (scm_recvfrom): take a port. return #f for address component if can't
3811 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3812 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3814 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3816 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3817 use separate data pointers, to allow them to be designed
3818 independently and reused.
3819 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3820 Renamed from catch_body, catch_handler, and uncaught_throw; made
3822 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3824 (scm_catch): Use the above.
3825 (scm_throw): Don't bother printing a message for an uncaught
3826 throw; we establish a default handler in init.
3827 * throw.h (scm_internal_catch): Prototype updated.
3828 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3830 (struct scm_body_thunk_data): New structure, used as data
3831 argument to scm_body_thunk.
3832 * init.c (struct main_func_closure): New structure, packaging up
3833 the data to pass to the user's main function.
3834 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3835 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3836 scm_internal_catch to establish a catch-all handler, using
3837 scm_handle_by_message. This replaces the special-case code in
3839 (invoke_main_func): Body function for scm_internal_catch; invoke
3840 the user's main function, using the main_func_closure pointer to
3841 decide what to pass it.
3842 * root.c (struct cwdr_body_data): Remove handler_proc member.
3843 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3844 (cwdr_handler): Removed.
3846 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3848 * socket.h (SCM_P): update bind prototype.
3849 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3850 include "feature.h".
3851 (scm_socket): return a port, not a file descriptor object.
3852 include "fports.h" and <unistd.h>
3853 (scm_bind): take a port, not a file descriptor object.
3854 take an extra argument for address args.
3856 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3857 INADDR_NONE, INADDR_LOOPBACK.
3859 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3861 * init.c: include net_db.h and not fdsocket.h.
3862 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3864 * Makefile.am: corresponding changes.
3865 * socket.h: renamed from fdsocket.h, fix names.
3866 * net_db.h: renamed from socket.h, fix names.
3867 * socket.c: renamed from fdsocket.c.
3868 remove _sys from procedure names.
3869 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3870 add "socket" to features list.
3871 * net_db.c: renamed from socket.c.
3872 remove _sys from procedure names.
3873 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3874 add "net-db" to features list.
3875 include "net_db.h". don't include <sys/socket.h> or
3878 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3880 * tags.h (scm_tags): Removed comma at end of last enumerator.
3882 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3884 Don't use GCC extensions to allocate space for debugging frames.
3885 (Here he goes again! Why do we put up with this?!)
3886 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3887 an scm_debug_info structure, not an in-line array of them. Add
3888 'info' member, to say how many vect elements we've used, for eval
3890 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3891 a new variable debug_info_end to mark the end of vect, instead of
3892 the address of the 'info' pointer itself.
3893 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3894 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3895 (SCM_APPLY): Explicitly allocate space for debug.vect.
3896 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3897 * stacks.c: Adjusted for new debug frame structure.
3898 (RELOC_INFO, RELOC_FRAME): New macros.
3899 (stack_depth, read_frames): Use them, and new scm_debug_frame
3900 element 'info', instead of magically knowing that eval frames have
3901 an info pointer sitting after vect.
3902 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3904 (scm_init_stacks): Formatting tweaks.
3906 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3908 Give GCC more control flow information, so it can be sure that
3909 variables aren't used uninitialized.
3910 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3911 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3912 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3913 scm_misc_error): Tell GCC that these functions never return.
3914 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3915 out the field type, call abort if SCM_ASSERT returns, to placate
3917 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3918 scm_wta ever returns. We can't handle this case anyway, and this
3919 gives the optimizer more information.
3920 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3921 scm_wta ever returns.
3923 In some cases, the code is fine, but GCC isn't smart enough to
3924 figure that out; this usually happens when one variable is only
3925 initialized and used when a particular condition holds true, and
3926 we know that condition will never change within a given invocation
3927 of the function. In this case, we simply initialize the variables
3928 to placate the compiler, hopefully to a value which will cause a
3929 crash if it is ever actually used.
3930 * print.c (scm_iprin1): Initialize mw_pos.
3931 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3932 * throw.c (scm_ithrow): Initialize dynpair.
3933 * unif.c (scm_uniform_vector_ref): Initialize cra.
3934 * struct.c (init_struct): Initialize prot.
3935 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3937 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3938 if EXPR contains no expressions.
3940 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3942 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3943 cause an infinite loop (???). So much for the algebraic
3944 equivalency of variable-sized arrays and alloca...
3946 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3948 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3949 a SCM boolean, not a C boolean.
3951 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3953 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3954 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3955 rules for raising scm_mtrigger. Previously, unfortunate but not
3956 unlikely circumstances could result in almost constant invokation
3957 of the gc. Now, this situations should be less likely, but they
3958 are not prevented completely.
3960 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3962 * numbers.c (scm_fuck): Procedure removed; looks like old test
3964 * numbers.h: Prototype removed.
3966 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3968 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3969 array to a pointer, to match my Nov 21 change in eval.c.
3971 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3973 * libguile.h: Added #include "libguile/backtrace.h", #include
3974 "libguile/stacks.h".
3976 * strings.c (scm_string scm_make_string scm_string_ref
3977 scm_string_set_x scm_string_equal_p scm_string_append):
3978 Bugfix according to scm patch from Aubrey Jaffer:
3979 Corrected long-standing
3980 (not (eqv? (integer->char 128)
3981 (string-ref (make-string 1 (integer->char 128)) 0)))
3982 bug found by John Kozak <jk@noontide.demon.co.uk>.
3984 * strports.c, strports.h: Make scm_eval_0str return the value of
3985 the last expression evaluated (previously, it returned void).
3987 * strports.c, strports.h: New function: scm_read_0str. Does what
3990 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3992 * simpos.c (scm_getenv): return #f if string can't be found in the
3993 environment instead of throwing an exception, for compatibility
3994 with numerous other systems.
3996 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3998 * Makefile.am (.c.x): Use guile-snarf.
3999 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
4001 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
4003 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4005 * backtrace.c (scm_display_error_message): Made non-static, and
4006 renamed from display_error_message.
4007 * backtrace.h (scm_display_error_message): Added extern decl.
4008 * throw.c (uncaught_throw): Use it to display the error message.
4010 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
4012 * inet_aton.c: Use #if 0, not #ifdef 0.
4014 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
4016 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
4017 to convert the returned value.
4018 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
4019 the offset argument.
4021 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4023 Add new interface to catch/throw, usable from C as well as
4025 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
4026 (scm_internal_catch): New function, replaces...
4027 (scm_catch_apply): Deleted.
4028 * throw.c (scm_catch_apply): Deleted; replaced with a more general
4029 mechanism which is a bit more code, but can be used nicely from C
4030 and implement the Scheme semantics as well.
4031 (scm_internal_catch): This is the replacement; it's named after
4032 the analogous function in Emacs.
4033 (scm_catch): Reimplemented in terms of the above.
4034 (struct catch_body_data, catch_body, catch_handler): New
4035 functions, used by scm_catch.
4036 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
4037 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
4038 support for new cwdr.
4040 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
4043 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
4045 * acconfig.h: Added DYNAMIC_LINKING symbol.
4046 * configure.in: Add option and checks for dynamic linking.
4047 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
4048 dynl.h: New files for dynamic linking support.
4049 * Makefile.am (libguile_a_SOURCES):
4051 (modinclude_HEADERS): Added "dynl.h".
4052 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
4054 * init.c (scm_boot_guile_1): Call
4055 scm_init_dynamic_linking to initialize dynamic linking support.
4057 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
4059 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
4060 (as we Schemers say). It needs to be global, so that I can tweak
4061 it for the proper operation of unexec.
4062 (scm_boot_guile_1_live): New variable, see above.
4064 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
4066 * guile-snarf.sh: Removed.
4067 * PLUGIN/guile.libs: Added dependency for -lm.
4068 * acinclude.m4: Renamed from aclocal.m4.
4069 * PLUGIN/greet: Removed.
4070 * Makefile.am, aclocal.m4: New files.
4071 * configure.in: Updated for Automake.
4073 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
4075 * eval.c (scm_definedp): Use top_level_lookup_closure_var
4076 and not top_level_lookup_thunk_var.
4078 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
4080 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
4082 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
4084 * eval.c (scm_definedp): Incompatibly changed to be a builtin
4085 Scheme function, instead of syntax. Single argument is now a
4088 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4090 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
4091 scm_ra_divide): Properly terminate statements passed as arguments
4092 to IVDEP macros. (Thanks to Bernard Urban.)
4094 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
4095 with non-constant sizes. (Thanks to Bernard Urban.)
4097 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4099 It's an "eval closure", not an "eval thunk." A thunk is a
4100 function of no arguments.
4101 * root.h (struct scm_root_state): Renamed
4102 top_level_lookup_closure_var from top_level_lookup_thunk_var.
4103 (scm_top_level_lookup_closure_var): Renamed from
4104 scm_top_level_lookup_thunk_var.
4105 * root.c (mark_root): Uses changed.
4106 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
4107 * init.c (scm_start_stack): Uses changed.
4108 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
4109 Change scheme-visible name to *top-level-lookup-closure* from
4110 *top-level-lookup-thunk*.
4112 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
4114 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
4115 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
4117 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
4119 * gc.c (struct scm_heap_seg_data): Doc fixes.
4121 * gc.c (scm_gc_sweep): Empty all segments' freelists before
4122 sweeping. Then, prepend each segment's free cells to its
4123 freelist, rather than wiping out the old value. (Thanks to Marius
4126 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
4127 scm_check_freelist, scm_debug_newcell): New functions and
4128 variables, for debugging freelist problems.
4129 * pairs.h (SCM_NEWCELL): New debugging version added.
4130 * gc.h (scm_debug_newcell): Added extern declaration, used by
4131 debugging version of SCM_NEWCELL.
4133 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4135 On some systems <libc.h> conflicts with <unistd.h>, and should not
4136 be #included at all.
4137 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
4138 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
4139 * configure.in: Call it.
4140 * posix.c, filesys.c: Use its results to decide whether or not to
4142 * configure, scmconfig.h.in: Rebuilt with autoconf and
4145 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4147 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
4148 pointer to the stdio stream before calling scm_setbuf0, so the
4149 latter will be able to retrieve it. I'm surprised this didn't
4150 segfault earlier. (Thanks to Christopher Lee.)
4152 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4154 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
4157 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4159 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
4160 number of stack narrowing specifier pairs. The first specifier in
4161 a pair controls inner border, the second the outer border. A
4162 number means cut that number of frames, a procedure object means
4163 cut until that object is found in operator position in a frame.
4165 * root.c (cwdr): Bugfix.
4167 * read.c: Recording of positions disabled by default.
4169 * procs.c (scm_closure_p): New function.
4171 * posix.c (scm_tmpnam): New function.
4173 * load.c: Added #include "throw.h".
4174 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
4177 * load.c, load.h (scm_read_and_eval_x): New function.
4179 * eval.c: Renamed debug option "deval" to "debug".
4181 (scm_eval_x): `eval!' is no longer accessible from the scheme
4182 level. Motivation: We can't allow operations which introduce
4183 glocs into the scheme level. Guile's type system can't handle
4184 these as data. Use `eval' or `read-and-eval!' as replacement.
4186 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
4187 SCM_CONSP since this is a macro!; Set vframe.prev to
4188 scm_last_debug_frame instead of 0. In this way we can look
4189 "above" the virtual start stack frame if we wish.
4190 (scm_debug_hang): New function: Useful for debugging Guile in
4191 certain tricky situations. Will probably be removed later...
4193 * debug.h: Changed semantics of debug option "backtrace". This
4194 option now only indicates whether we want automatic backtrace at
4197 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4199 * ports.c: #include "filesys.h"
4200 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
4202 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
4203 Motivation: This is system specific code which is related to file
4204 I/O. It also may use select. Added code by Gary Houston to
4205 detect presence of character in stdio buffers.
4207 * libguile.h: #include "libguile/libpath.h"
4209 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4210 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4211 SCM_SITE_DIR; Install libpath.h among the other include files.
4213 * load.c, load.h (scm_sys_package_data_dir): New function.
4215 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4217 * stacks.h: Bugfix: Don't use tail-array length field as stack
4218 length field! This screwed GC.
4220 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4222 * _scm.h: Added #ifndef around definition of macros min and max.
4224 * __scm.h: Added hooks for threads to plugin to in ints protection
4225 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4226 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4227 the main code in these macros duplicated and spread over multiple
4228 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4229 SCM_THREAD_SWITCHING_CODE.
4231 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4233 * snarf.h: New file.
4234 * guile-snarf.sh: New file.
4235 * Makefile.in (inner_h_files): Added snarf.h
4236 (ancillary, install, uninstall, distclean): Added actions for
4238 (.c.x): Use guile-snarf.
4239 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4240 (gen_c_files): Note that these depend on guile-snarf.
4241 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4242 now in "snarf.h". Added #include "snarf.h" to get them.
4243 * libguile.h: Added #include "snarf.h".
4244 (Patches applied and tweaked by Jim Blandy.)
4246 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4248 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4249 standards suggest against providing prototypes for system
4250 functions. Thanks to Greg Troxel.
4252 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4254 * strports.c (scm_eval_0str): New function.
4255 #include "read.h", to get prototype for scm_read.
4256 * Makefile.in (strports.o): Update dependencies.
4257 * strports.h: New prototype.
4259 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4260 scheme name from "int?" to "integer?". It seems to do the job.
4261 * numbers.h: Rename prototype too.
4262 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4265 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4266 scm_num_eq_p): Rename these according to R4RS conventions: call
4267 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4268 to making libguile R4RS compliant without ice-9...
4270 * load.c (scm_sys_search_load_path): Search for files under all
4271 extensions listed in the %load-extensions variable. If FILENAME
4272 is absolute, return it unchanged, without searching the load path.
4273 (scm_loc_load_extensions): New variable, pointing to
4274 %load-extensions' value cell.
4275 (scm_init_load): Initialize it, and the value it points to.
4276 (scm_primitive_load_path): Improve error reporting.
4278 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4279 of new Scheme variable %load-hook.
4280 (scm_primitive_load): Apply %load-hook to filename.
4282 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4284 * configure.in: add tests for figuring out whether buffered data
4285 is available in a FILE structure, which is needed by char-ready.
4287 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4290 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4291 exceptions using misc_error instead of syserror. It seems a bit
4292 odd to throw an exception if a string can't be found in the
4293 environment, but it's consistent with open-file, stat etc.
4294 (simpos.h): remove sys_ from getenv.
4296 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4297 occurs, throw an error instead of returning errno. Return value
4299 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4301 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4303 * filesys.c (scm_stat2scm): derive file type and permissions from
4304 the stat mode and append them to the returned vector.
4305 There isn't much overhead in doing this and it avoids the need to
4306 work with S_IRUSR et al. in Scheme.
4307 Define symbols scm_sym_regular etc.
4308 (scm_init_filesys): don't intern S_IRUSR etc.
4310 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4311 and s_primitive_load_path.
4313 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4315 * error.h: don't declare error symbols. prototype for scm_misc_error.
4317 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4320 * error.c: use SCM_SYMBOL to set up error keys.
4321 scm_misc_error: new procedure.
4323 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4325 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4326 between `#!' and `!#' is ignored.
4327 (skip_scsh_block_comment): New function.
4329 * feature.c (scm_set_program_arguments): New argument, FIRST.
4330 * feature.h: Update prototype.
4331 * init.c (scm_boot_guile_1): Pass new argument to
4332 scm_set_program_arguments.
4334 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4336 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4337 (scm_boot_guile): Call scm_set_program_arguments here, later than
4338 the old initialization.
4340 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4341 initialization procedure.
4342 - Delete in, out, err arguments; there are other perfectly good
4343 ways to override these when desired.
4344 - Delete result argument; this function shouldn't ever return.
4345 - Rename init_func argument to main_func, for less confusion.
4346 - Delete boot_cmd argument; main_func is more general.
4347 -Add 'closure' argument, to help people pass data to main_func
4348 without resorting to global variables.
4349 - Abort if reentered; don't bother returning an error code.
4350 - Call scm_init_standard_ports to set up the default/current
4351 standard ports; no need to pass them to scm_start_stack.
4352 - Remove code to evaluate the boot_cmd, and start the repl; let
4353 the user do something like that in main_func if they want.
4354 - Remove code to package up a return value; main_func can do any
4356 - Call exit (0), instead of returning.
4357 (scm_start_stack): Don't initialize the I/O ports here; that's
4358 weird. Delete in, out, err arguments. Move guts to
4359 scm_init_standard_ports, scm_stdio_to_port.
4360 (scm_init_standard_ports): New function, to set up current and
4361 default standard ports.
4362 (scm_start_stack, scm_restart_stack): Make these static.
4363 * init.h (scm_boot_guile): Adjust declaration.
4364 (scm_start_stack, scm_restart_stack): Remove externally
4365 visible declarations for these.
4366 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4368 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4369 written out several times in scm_start_stack.
4370 * fports.h: New declaration for the above.
4372 * feature.c (scm_set_program_arguments): New function.
4373 * feature.h: New declaration for the above.
4375 * ports.c: Formatting tweak.
4377 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4379 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4380 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4381 for obtaining the address of a car or cdr field. Motivation:
4382 &SCM_CXR make assumptions about the internal structure of the
4385 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4386 Motivation: see SCM_CXRLOC.
4388 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4389 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4390 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4391 Motivation: Safer use. Some other macros are defined in terms of
4392 these operations. If these are defined using the SCM_SETCXR
4393 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4394 to inefficiency and an <e1> with side-effects could potentially
4395 break. Also, these particular operations are heavily utilized in
4396 the garbage collector. In unoptimized code there will be a
4399 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4400 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4401 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4402 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4403 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4404 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4405 vports.c: Cleaned up use of pairs: Don't make any special
4406 assumptions about the internal structure of selectors and
4407 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4408 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4409 (Among other things, this change makes it easier to build Guile
4410 with certain compilers which have problems with casted lvalues.)
4412 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4414 * stacks.c: Improve selection of relevant stack frames when making
4415 a stack object. Introduce one level of indirection in the stack
4416 object to make it possible to "narrow" to a certain region of the
4417 stack. This facilitates making use of more clever algorithms (not
4418 implemented) for selecting relevant frames and gives a cleaner
4419 design since selection of frames can be done independently of
4420 extraction of frames from the real stack.
4421 (scm_stack_id): Also take #t as argument which means look at
4424 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4425 Turn n_tail into an integer directly representing current number
4426 of frames in stack. Add field tail.
4428 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4430 * debug.c (scm_make_memoized): Made it available at scheme level.
4431 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4432 SCM_NIMP before applying heavier predicates in argument checking.
4433 (scm_local_eval): Also take memoized object as argument.
4435 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4436 aren't created with zero length, but should such a strange
4437 creature suddenly turn up...
4439 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4441 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4442 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4444 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4446 * variable.c (scm_make_variable): Make the name hint optional, as
4448 (anonymous_variable_sym): Renamed from variable_sym. All uses
4451 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4452 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4453 of scm_primitive_load_path was also changed to
4454 "primitive-load-path", from "%try-load-path". Callers changed.
4455 We'd like to respect the convention that a function named
4456 "try-mumble" should behave just like the function called "mumble",
4457 but return #f instead of signalling some error.
4458 * load.h: Rename prototypes.
4460 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4462 * print.c (make_print_state, grow_print_state), print.h: Modified
4463 the print state representation: Don't use a tail array for
4464 recording of circular references. Resizing of the print state
4465 structure invalidates the print state pointer. To avoid passing
4466 around an indirect print state reference to all printing
4467 functions, we instead let the print state reference a resizable
4470 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4472 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4473 Don't crash when passed an improper list terminated by a
4474 non-immediate value.
4476 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4478 Allocate data for structures on an eight-byte boundary, as
4479 required by the tagging system.
4480 * struct.c (alloc_struct): New function.
4481 (scm_make_struct, scm_make_vtable_vtable): Call it.
4482 * struct.h (scm_struct_n_extra_words): Bump to 3.
4483 (scm_struct_i_ptr): New "field".
4484 * gc.c (scm_gc_sweep): When we need to free the data, use the
4485 information stored by alloc_struct to find the beginning of the
4486 block allocated to the structure, so we can free it.
4488 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4490 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4493 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4494 (scm_debug_info): New member: id.
4496 * stacks.c: Stacks are now represented as structs; Stacks have an
4497 id given to them by `start-stack'.
4498 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4500 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4501 Changed stack representation.
4503 * debug.c (scm_procedure_name): Try procedure property `name' for
4504 compiled closures aswell.
4506 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4508 * eval.c: scm_i_name moved to gsubr.c
4509 (scm_m_define): Record names of all kinds of procedure
4510 objects. (Earlier, only closures were recorded.)
4512 * procprop.h: Added declaration of scm_i_name.
4514 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4515 (scm_make_gsubr): Record names of compiled closures.
4517 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4519 * debug.c, debug.h: Removed obsolete code.
4521 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4522 stacks.c: Renamed regs --> scm_contregs.
4524 * print.c (scm_free_print_state): Cleanup print state before
4525 returning it to pool. It is better to do it here than in
4526 scm_prin1 since scm_prin1 is called often.
4528 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4529 s_set_source_property_x): Check that first argument is a pair or a
4532 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4533 scm_i_line, scm_i_column and scm_i_breakpoint global.
4535 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4536 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4539 * debug.h: Added debug object smob declaration and macro
4542 * configure.in: Build with backtrace.o and stacks.o if debug
4545 * Makefile.in: Added entries for new files: backtrace.c,
4546 backtrace.h, stacks.c and stacks.h.
4548 * symbols.c (scm_sym2ovcell): Fixed documentation.
4550 * _scm.h (min, max): Added.
4552 * async.c: Moved `min' macro to _scm.h.
4554 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4555 SCM_BACKTRACE_INDENT.
4557 * eval.c: Added new debug options `maxdepth' and `indent'.
4559 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4561 * print.h: Added selector SCM_PRINT_STATE.
4563 * print.c: New functions: scm_make_print_state,
4564 scm_free_print_state.
4566 * print.h: Added declarations for scm_make_print_state,
4567 scm_free_print_state.
4569 * debug.c (scm_m_start_stack): New acro.
4571 * debug.h: Small cleanup.
4573 * init.c (scm_boot_guile_1): Moved scm_init_debug below
4576 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

4596 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
4597 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
4598 declare functions with prototypes. (Patch thanks to Marius
4601 More prototype-related changes from Marius Vollmer:
4602 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4603 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4604 * ports.h (ptobfuns): Added prototypes. This means some casting in
4606 * fports.c: Added casts for initializations, since the functions
4607 are defined to take FILE * as their stream argument, not SCM.
4608 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4609 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4610 to `char *str_data' to conform to prototype.
4612 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4614 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4616 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4618 * stime.c, stime.h: use SCM_P method.
4620 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4622 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4623 be given at least two arguments. Insist that lst's last element
4624 be a list, but don't make any requirements of its predecessors.
4626 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4628 * eval.c (scm_nconc2last): Revert last change; there seems to be
4629 other stuff going on here.
4631 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4633 * eval.c (scm_nconc2last): Make sure that each element of lst
4634 (which is a list of argument lists, except for the tail) is a
4635 proper list, i.e., finite and terminated by '().
4637 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4639 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4642 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4643 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4646 * vectors.c (scm_make_vector): Fill vectors with the undefined
4647 value, to help make Guile Scheme code more portable to other
4650 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4651 * symbols.h, tags.h: Doc fixes.
4653 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4655 * async.c (scm_take_signal): Doc fixes.
4657 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4659 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4660 want to subtract it from the modulus; we just want to leave it
4663 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4665 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4668 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4670 * throw.c (scm_catch_apply): Finished implementation of
4673 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4675 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4677 (scm_init_filesys): set "i/o-extensions" feature.
4680 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4682 * Makefile.in (root.o): Correct dependencies.
4684 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4686 * Makefile.in: Added dependency entry for root.o.
4688 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4689 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4691 * init.c (scm_start_stack): Set initial root continuation number
4694 * procs.c: New function: scm_thunk_p.
4696 * procs.h: Added declarations of scm_thunk_p.
4698 * root.c: Renamed `call-with-new-root' -->
4699 `call-with-dynamic-root'.
4700 (cwdr): Removed allocation of new root state. This should be done
4701 separately by use of scm_make_root.
4702 (scm_apply_with_dynamic_root): New function: Does what it
4703 sounds like. Needed when spawning threads.
4705 * root.h: Added member last_debug_frame to root state.
4706 Added #include "libguile/debug.h"
4708 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4709 arguments. The motivation is that code in root.c needs catch
4710 functionality, and we want to avoid code duplication.
4711 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4712 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4713 handlers that run without popping the stack into the dynwind
4716 * throw.h: Added prototypes for scm_catch_apply and
4719 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4721 * root.h (scm_root, scm_set_root): Decouple thread support details
4722 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4723 SCM_SET_THREAD_LOCAL_DATA.
4725 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4726 and tortoise scanning loop.
4728 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4730 * Makefile.in: Rebuild dependencies.
4732 * libguile.h: #include "libguile/print.h" before "smob.h", since
4733 the latter uses the print_state structure.
4735 * throw.c (scm_ithrow): Use the correct variable when checking to
4736 see if a given element of scm_dynwinds is a valid catch.
4738 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4739 structure, abort; don't just silently ignore the garbage.
4741 * _scm.h: #include "print.h" here, since it seems to be used just
4743 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4744 strports.c, unif.h: Don't #include "print.h".
4746 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4748 * feature.h (scm_loc_features): Removed external declaration.
4749 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4751 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4753 * feature.c (scm_init_feature): Added threads feature (needs to be
4754 initialized here, since features doesn't exist when
4755 scm_init_threads is called).
4757 * libguile.h: Added #include "libguile/../threads/threads.h".
4758 (This is a kludge to get thread support working. This should be
4761 * configure.in, acconfig.h: Added flags for thread support.
4763 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4766 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4767 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4770 * _scm.h: Added conditional #include "threads.h"
4772 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4773 SCM_THREADS_SWITCHING_CODE.
4775 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4776 allocate the basic dynamic root object.
4777 (scm_boot_guile): Added call to scm_init_root.
4779 * root.c, root.h: Added root smob.
4780 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4781 functions: Implements dynamic roots mostly according to spec in
4782 SCM manual. Main difference is that the second argument is a
4783 throw handler rather than an error "thunk".
4785 * root.h: Added declaration of scm_init_root.
4787 * root.c: Added #include "genio.h", #include "smob.h", #include
4788 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4790 (scm_init_root): Added #include "root.x".
4792 * throw.c: Added #include "stackchk.h"
4793 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4794 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4795 can be used in scm_call_with_new_root; Added reenabling of stack
4796 checking when catching a throw.
4798 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4800 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4802 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4803 element is not found, as per R4RS.
4805 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4807 * list.c: Doc fixes throughout.
4809 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4811 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4812 declare the char * to be const. Avoids a warning in rgx.c.
4814 * ports.h: spelling fix.
4816 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4819 * load.c (scm_sys_try_load_path): throw an error if file not found
4820 (like it says it in NEWS).
4822 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4824 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4825 PROPS slot to '(), not #f; it's an empty alist.
4827 * throw.h, throw.c: Use SCM_P instead of #if hair.
4829 Remove special support for uncaught throws; see throw.c for
4831 * throw.c (uncaught_throw): New function.
4832 (scm_ithrow): Call uncaught_throw if we don't find a throw
4833 target; don't mess with scm_bad_throw_vcell.
4834 (scm_bad_throw_vcell): Variable deleted.
4835 (scm_init_throw): Don't initialize it.
4837 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4840 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4842 * numbers.c (scm_istr2int): If the number is short (as most
4843 numbers are), just call scm_small_istr2int to deal with it.
4844 (scm_small_istr2int): New function, created by un-#ifdefing the
4845 non-bignum version of scm_istr2int and renaming it.
4847 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4849 * load.c (scm_sys_try_load): don't check whether value returned
4850 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4851 Change the Scheme name from %try-load to primitive-load.
4853 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4854 Can avoid passing a message, allowing it to be derived in the
4855 error handler (e.g., if we want to throw to the key both from
4858 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4860 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4861 references now have a new appearance which is more compact and
4862 also gives a clue about what the target of the reference is.
4863 By setting parameters in the print state, more fancy printing can
4864 be achieved. This is used by the (not yet commited) backtrace
4867 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4869 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4872 * print.c: Added #include "struct.h". Removed function
4875 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4876 scm_iprin1. Removed prototype for scm_prlist.
4878 * arbiters.c (prinarb),
4879 async.c (print_async),
4880 debug.c (prindebugobj, prinmemoized),
4881 eval.c (prinprom, prinmacro),
4882 filesys.c (scm_fd_print, scm_dir_print),
4884 mallocs.c (prinmalloc),
4885 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4886 smob.h (scm_smobfuns),
4887 srcprop.c (prinsrcprops),
4889 unif.c, unif.h (scm_raprin1, rapr1),
4890 variable.c (prin_var): Changed argument `int writing' to
4891 `scm_print_state *pstate'.
4893 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4894 that it will be called before scm_init_print.
4896 * print.c (scm_prin1): Print states are now allocated when calling
4897 scm_prin1 and then passed around to all printing functions as an
4898 argument. A cache `print_state_pool' enables reuse of print
4900 (scm_make_print_state): New function.
4901 (scm_iprin1): Adaption to print states.
4902 (scm_iprlist): An initial "hare and tortoise" scan brings down
4903 time complexity to O (depth * N). (Better time complexity will be
4904 achieved when the printing code is completely rewritten.)
4906 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4908 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4909 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4910 it gets done whether or not the cache variable has a value.
4912 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4914 Distinguish #f and ().
4915 * __scm.h: #undef SICP.
4916 * pairs.h (SCM_EOL): Delete this definition, equating it with
4918 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4919 the value it used to have. Doc fixes, too.
4921 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4923 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4924 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4925 Lord's implementation of structs, allowing for tail arrays as
4926 described in the manual. Also fixed some bugs. (Both the interface
4927 and the implementation should be improved.)
4929 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4931 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4932 People who whish to see the source can do `(print-enable 'source)'.
4933 Removed #ifdef DEBUG_EXTENSIONS.
4935 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4937 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4938 integer (assuming for now accepting an integer is a good thing).
4940 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4941 %S will be used instead for write'ing arguments.
4943 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4944 asserts. fix a few other asserts.
4945 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4946 scm_uniform_vector_ref, scm_array_set_x,
4947 scm_dimensions_to_unform_array): change args in
4948 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4949 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4950 scm_substring_fill_x): likewise.
4951 gsubr.c (scm_gsubr_apply): likewise.
4952 eval.c (SCM_APPLY): likewise.
4954 * eval.c (4 places): replace scm_everr with lgh_error or
4957 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4958 scm_memory_error): new procedures.
4959 scm_everr: deleted. can use scm_wta, dropping first two args.
4960 scm_error: convert NULL subr to SCM_BOOL_F.
4962 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4965 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4968 * error.c, error.h: new error keys: scm_arg_type_key,
4969 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4971 scm_wta: reimplement using lgh_error instead of scm_everr.
4973 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4975 * gdbint.c: scm_lread now has one more argument.
4977 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4978 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4979 loading source from non-file ports, which, e. g., happens when
4980 using the Emacs interface).
4982 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4985 * read.c: Added code for recording of positions of source code
4986 expressions; New functions: recsexpr, scm_lreadrecparen;
4987 _scm_make_srcprops --> scm_make_srcprops
4988 (scm_flush_ws): Removed updating of positions counters. This work
4989 is already done by scm_gen_getc
4991 * read.h: Added prototype for scm_lreadrecparen
4993 * print.c: Added #include "alist.h"
4995 * eval.c: Added #include "hash.h"
4997 * eq.c: Added #include "ramap.h"
4999 * options.c: Documentation fixes.
5001 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
5002 (scm_init_srcprop): Adjusted size of initial source-whash. Name
5003 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
5004 --> scm_make_srcprops
5006 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
5007 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
5008 function calls in the definition of the whash access macros.
5010 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
5012 * init.c (scm_boot_guile): Add level of indirection to
5013 scm_boot_guile_1() to ensure that stack base pointer is properly
5014 initialized. There was no guarantee that variable i was the
5015 highest/lowest variable on stack (i.e. the call frame of
5016 scm_boot_guile was not completely protected from gc).
5018 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
5020 * ports.h (scm_port_table): put back file_name, it will be used to
5021 support debugging. Undo related changes in fports.c, ioext.c,
5024 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5026 * ports.h (scm_port_table): remove file_name member for now, it seems
5028 * fports.c (scm_open_file): don't set file_name in PTAB.
5029 (prinfport): don't use file_name in PTAB.
5030 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
5031 * ports.c (scm_add_to_port_table): don't intialize file_name.
5032 (scm_port_file_name): remove for now.
5033 * gc.c (scm_gc_mark): don't mark PTAB file_name.
5035 * fports.h (scm_mkfile): prototype deleted.
5036 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
5038 * debug.c, unif.c: use scm_out_of_range instead of
5039 wta for range errors (ASSERT still needs work).
5041 * error.c, error.h (scm_out_of_range): new procedure.
5043 * error.c, error.h (scm_out_of_range_key): new key.
5045 * posix.c (scm_sync): #else was missing.
5047 * error.c, error.h: append _key to names scm_num_overflow and
5050 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
5051 of consing an empty list.
5052 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
5053 of macros, saves code and string space.
5054 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
5055 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
5056 lower case. Rename scm_syserror_m to scm_syserror_msg.
5057 error.h: prototypes for new procedures.
5059 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
5061 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
5063 * error.c, error.h: setup scm_num_overflow key.
5065 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
5066 Remove definition of SCM_OVSCM_FLOW.
5068 * fports.c (scm_open_file): use SCM_SYSERROR_M.
5070 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
5071 explicit message and args.
5073 * error.c, error.h, __scm.h: change system_error_sym to
5076 * error.c (system_error_sym): remove leading %% from the Scheme name
5079 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
5081 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5083 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
5084 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
5085 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
5086 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
5087 renamed. (These were introduced by unsupervised name
5090 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5092 * print.c: Added code for detection of circular references during
5093 printing. (init_ref_stack, grow_ref_stack): New functions. Added
5094 a hook for printing of closures (accessible via print options).
5095 This leads to a split of calls to scm_iprin1 into two classes:
5096 elementary print operations (e. g. the code which prints a smob)
5097 still use scm_iprin1 while top level calls (like scm_display) use
5098 scm_prin1. scm_prin1 begins by clearing the data structure used
5099 to record reference information.
5101 * print.h: Added declarations of scm_prin1 and scm_prlist.
5103 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
5105 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
5107 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
5109 * error.c (err_head): scm_iprin1 --> scm_prin1
5111 * debug.c: Adjusted header comment.
5115 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
5117 * strerror.c: Doc fix.
5119 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5121 * gdbint.c (gdb_read): Now possible to run during GC.
5122 (unmark_port, remark_port): New functions.
5124 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
5126 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
5127 of allocating a new string object. Also, increase size by
5128 the factor 2 instead of 1.5.
5130 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
5132 * __scm.h (SCM_P): Corrected to run under traditional C.
5134 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
5137 * async.c: Calls to scm_sysintern corrected.
5139 * async.h (scm_async_clock): Redundant declaration removed.
5141 * continuations.c (scm_dynthrow): Redundant declaration removed.
5143 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
5144 Definition typos corrected.
5146 * debug.h: Missing declarations of functions in debug.c added
5149 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
5150 Missing declarations to functions in eval.c added.
5152 * filesys.c: Possibly uninitialized variable rv.
5154 * gc.h (scm_object_addr, scm_unhash_name): Missing
5155 declarations of functions defined in gc.c added.
5157 * genio.c: Possible typos str_data -> wstr_data. ???
5159 * genio.c: Possibly unintended shadowing of local variable
5160 `int c' (gotos out of scope of inner `c'). ???
5162 * init.c: Uninitialized `SCM last' may be used.
5164 * ioext.h: (scm_sys_isatty_p): Typo.
5166 * list.h (scm_list_head): Missing prototype for function in
5169 * numbers.c (scm_two_doubles): Changed from extern to static
5170 (is used only within numbers.c).
5172 * numbers.h: Repeated declarations removed.
5174 * ports.h (scm_close_all_ports_except): Declaration for the
5175 function defined in ports.c added.
5177 * posix.h: Missing declarations added.
5179 * procs.h (scm_make_subr_opt): Missing declaration added.
5181 * socket.h (scm_sys_gethost): Missing declaration added.
5183 * socket.h: Redundant declarations removed (they are in fdsocket.h).
5185 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
5186 Missing declarations added.
5188 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
5190 * struct.c: Uninitialized variable `SCM answer' may be used.
5192 * unif.c (l2ra): Declaration prototype.
5194 * unif.c (scm_array_equal_p): Dummy definition removed (it is
5195 defined in ramap.c).
5197 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
5198 Redundant declarations removed (they are in ramap.h).
5200 * variable.h (scm_make_udvariable,
5201 scm_make_undefined_variable): Declaration corrected to
5202 correspond variable.c.
5204 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
5205 Missing declarations added.
5207 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5209 * Makefile.in (distclean): Don't forget to delete fd.h.
5211 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5213 * fd.h.in, tags.h: Trivial cleanups.
5215 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5216 marksweep.h just declared functions from gc.c.
5217 * gc.h, libguile.h: Don't #include "marksweep.h".
5218 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5219 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5220 dependencies updated.
5222 * libguile.h: Don't #include "files.h"; it's been deleted.
5224 * files.c (scm_sys_delete_file): Moved to filesys.c.
5225 File is now empty; deleted.
5227 * filesys.c: scm_sys_delete_file is now here. Remove
5228 #if's; they seem to rely on remnants of an old portability
5229 regimen. If the problems come up again, solve them properly,
5230 using autoconf. Specifically: Don't test M_SYSV, and #define
5231 remove to be unlink if it's #defined; don't use remove just
5232 because HAVE_STDC_HEADERS is #defined.
5233 * filesys.h: Add declarations for scm_sys_delete_file.
5234 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5235 files.o, files.h, files.c, and files.x.
5236 * init.c: Don't #include "files.h", and don't call scm_init_files.
5238 Use SCM_P instead of PROTO; the latter intrudes on the user's
5240 * params.h: Deleted; definition of SCM_P moved to...
5241 * __scm.h: ... here, where it replaces PROTO macro.
5242 * libguile.h, smob.h: Don't #include "params.h".
5243 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5244 smob.h: Fix prototypes accordingly.
5245 * Makefile.in: Update dependencies.
5246 (inner_h_files): Remove params.h.
5248 * gc.c: #include "gc.h"; every module should include its header,
5249 to let the compiler cross-check the declarations against the
5252 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5253 simpos.h: #include "libguile/__scm.h".
5255 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5257 * init.c: Don't forget to #include smob.h and init.h.
5258 * Makefile.in: Dependencies updated.
5260 * smob.h: Use PROTO instead of #if __STDC__.
5262 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5264 * __scm.h: Doc fixes.
5266 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5267 <angles>; this allows `make depends' to work properly.
5269 * libguile.h: #include smob.h and pairs.h before the others; they
5270 define typedefs used by other headers.
5272 C files should #include only the header files they need, not
5273 libguile.h (which #includes all the header files); the pointless
5274 recompilation was wasting my time.
5275 * Makefile.in (all .o dependency lists): Regenerated.
5276 * libguile.h: Don't try to get a definition for size_t here...
5277 * __scm.h: Do it here.
5278 * _scm.h: Since this is the internal libguile header, put things
5279 here that all (or a majority) of the libguile files will want.
5280 Don't #include <libguile.h> here; that generates dependencies on
5281 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5282 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5283 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and
5285 * alist.c: Get "eq.h", "list.h", "alist.h".
5286 * append.c: Get "append.h", "list.h".
5287 * arbiters.c: Get "arbiters.h", "smob.h".
5288 * async.c: Get "async.h", "smob.h", "throw.h", "eval.h".
5289 * boolean.c: Get "boolean.h".
5290 * chars.c: Get "chars.h".
5291 * continuations.c: Get "continuations.h", "dynwind.h", "debug.h",
5293 * debug.c: Get "debug.h", "feature.h", "read.h", "strports.h",
5294 "continuations.h", "alist.h", "srcprop.h", "procprop.h", "smob.h",
5295 "genio.h", "throw.h", "eval.h".
5296 * dynwind.c: Get "dynwind.h", "alist.h", "eval.h".
5297 * eq.c: Get "eq.h", "unif.h", "smob.h", "strorder.h",
5299 * error.c: Get "error.h", "throw.h", "genio.h", "pairs.h".
5300 * eval.c: Get "eval.h", "stackchk.h", "srcprop.h", "debug.h",
5301 "hashtab.h", "procprop.h", "markers.h", "smob.h", "throw.h",
5302 "continuations.h", "eq.h", "sequences.h", "alist.h", "append.h",
5304 * fdsocket.c: Get "fdsocket.h", "unif.h", "filesys.h".
5305 * feature.c: Get "feature.h".
5306 * files.c: Get "files.h".
5307 * filesys.c: Get "filesys.h", "smob.h", "genio.h".

5380 * weaks.c: Get "weaks.h".
5382 * stackchk.h: #include "libguile/debug.h",
5384 * print.h, read.h: #include "options.h", since everyone who uses
5385 either of these files will need that.
5387 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5388 anyone who uses this file will need them to define the smob
5389 printing functions. Also, get markers.h, since people will need
5390 to #define the mark functions.
5392 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5393 * ports.h: ... to here.
5395 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5396 don't rely on archaic C default type rules.
5398 * fports.h: #include "libguile/ports.h", since you need that in
5399 order to parse this.
5401 * genio.h: #include "libguile/print.h", because you need that to
5402 parse this; don't bother #including "ports.h", since print.h gets
5405 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5407 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5408 this; it's now a reference to an element of *scm_root.
5410 * debug.h: Don't #include "options.h"; the compiler won't be able
5411 to find that once the headers are installed; instead, #include
5412 "libguile/options.h".
5413 * gc.h: Same, with marksweep.h.
5414 * mbstrings.h: Same, with symbols.h.
5415 * scmhob.h: Same, with _scm.h.
5416 * smob.h: Same, with params.h.
5418 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5419 C files; there's no need for this, and it forces recompilations
5422 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5424 * error.c (scm_error): declare scm_error_callback.
5426 * error.h: prototype for scm_error_callback.
5428 * __scm.h: define lgh_error.
5429 (SCM_SYSERROR): redefine using lgh_error.
5431 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5433 * error.c (scm_error): new procedure.
5435 * error.h: prototype for scm_error.
5437 * Makefile.in (install): install scmconfig.h from the current
5438 directory, not $(srcdir).
5440 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5442 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5443 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5444 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
5445 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
5446 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,

5449 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5450 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5451 vports.h, weaks.h: #include "libguile/__scm.h", not
5452 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5453 dependencies are within libguile properly.
5455 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5457 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5458 when scmconfig.h doesn't exist.
5460 * load.c (scm_sys_try_load): Correct spelling.
5462 * feature.c (scm_loc_features): Make this static.
5464 * Makefile.in (libpath.h): Omit trailing slash from path. We
5465 shouldn't require it of users, so why put it here?
5467 Move code to initialize and search %load-path from ice-9 to C
5468 code, so we can use the load-path to find the ice-9 boot code;
5469 this makes it easier to run Guile without installing it. See
5470 corresponding changes in guile/Makefile.in.
5471 * feature.c: Move stuff concerned with the load path to load.c.
5472 (scm_compiled_library_path): Deleted.
5473 Don't #include libpath.h here.
5474 * feature.h: Don't mention scm_compiled_library_path.
5475 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5476 <sys/stat.h>, and <unistd.h> (if present).
5477 (R_OK): #define if the system hasn't deigned to.
5478 (scm_loc_load_path): New variable.
5479 (scm_init_load_path, scm_sys_search_load_path,
5480 scm_sys_try_load_path): New functions.
5481 (scm_init_load): Initialize scm_loc_load_path to point to the
5482 value cell of the Scheme %load-path variable.
5483 * load.h: Add declarations for scm_sys_search_load_path,
5484 scm_sys_try_load_path.
5485 * init.c: Call scm_init_load_path.
5486 * Makefile.in (feature.o, load.o): Dependencies updated.
5488 * load.c, load.h: Rewrite using PROTO macro.
5490 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5492 * gc.c (scm_cellp): New function: C predicate to determine if an
5493 SCM value can be regarded as a pointer to a cell on the heap.
5495 * gc.h: Added declaration of scm_cellp.
5497 * gdb_interface.h: New file: The GDB interface header from the GDB
5500 * gdbint.c: New file: GDB interface.
5502 * gdbint.h: New file: GDB interface.
5504 * libguile.h: Added #include <libguile/gdbint.h>.
5506 * init.c (scm_boot_guile): Added scm_init_gdbint.
5508 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5509 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5510 found if object files and source are kept separate).
5512 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5514 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5516 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5518 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5519 TK_SRC_DIR; they're not relevant any more.
5521 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5522 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5524 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5526 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5527 search path, so we can find the <libguile/MUMBLE.h> headers.
5529 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5531 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5532 implicit in the .c.o rule.
5533 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5536 Put the library path in a header file, instead of passing it on
5537 the command line in every compilation.
5538 * Makefile.in (libpath.h): New target.
5539 (feature.o): Depend on libpath.h.
5540 (clean): Delete libpath.h.
5541 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5542 * feature.c: ... #include "libpath.h" here.
5543 * .cvsignore: Ignore libpath.h.
5545 Don't install the unwashed masses of Guile header files in the
5546 main #include path; put most of them in a subdirectory called
5547 'libguile'. This avoids naming conflicts between Guile header
5548 files and system header files (of which there were a few).
5549 * Makefile.in (pkgincludedir): Deleted.
5550 (innerincludedir): New variable; this and $(includedir) are enough.
5551 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5552 (installed_h_files): Divide this up. Now this variable lists
5553 those header files which should go into $(includedir) (i.e. appear
5554 directly in the #include path), and ...
5555 (inner_h_files): ... this new variable says which files appear in
5556 a subdirectory, and are referred to as <libguile/mumble.h>.
5557 (h_files): List them both.
5558 (install): Create innerincludedir, not pkgincludedir. Put
5559 the installed_h_files and inner_h_files in their proper places.
5560 (uninstall): Corresponding changes.
5561 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5562 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5563 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5564 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5565 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5566 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5567 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5568 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5569 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5570 vports.h, weaks.h: Find __scm.h in its new location.
5571 * __scm.h: Find scmconfig.h and tags.h in their new locations
5572 (they're both "inner" files).
5574 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5576 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).

5580 * posix.c: Doc fixes.
5582 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5584 * socket.c: Don't include a prototype for inet_aton; just use a
5585 K&R style declaration, to avoid warnings but minimize the chance
5586 of conflicts with the system.
5588 On NextStep, <utime.h> doesn't define struct utime, unless we
5589 #define _POSIX_SOURCE before #including it.
5590 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5591 * acconfig.h: New comment text for above CPP symbol.
5592 * configure.in: Call it.
5593 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5595 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5597 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5598 testing for __EMX__.
5600 * posix.c: #include <libc.h>, if it exists.
5602 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5603 don't even know if the latter exists.
5605 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5606 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5607 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5609 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5611 (scm_init_posix): Use them when initializing the Scheme constants
5614 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5616 * Makefile.in (libdir, includedir, bindir): Use the
5617 autoconf-supplied values, instead of deriving them ourselves.
5618 (pkgincludedir, datadir, pkgdatadir): New variables.
5619 (install, uninstall): Put the header files in a special
5620 subdirectory, not in the main search path.
5622 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5623 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5625 * Makefile.in (IMPLPATH): Deleted; never used.
5627 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5628 on the Tcl/Tk source any more.
5629 (INCLUDE_CFLAGS): Remove references to the above.
5631 * Makefile.in (version.o): Corrected dependencies.
5633 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5635 * libguile.h: #include "version.h"
5637 * init.c (scm_boot_guile): Call scm_init_version.
5638 * gscm.c (gscm_run_scm): Call scm_init_version.
5640 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5641 GUILE_VERSION): AC_DEFINE these.
5642 (acconfig.h): #undef the above symbols.
5644 * Makefile.in (libobjs): Add version.o.

5648 (version.o): New rule.
5649 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5650 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

5659 weaks.o): Add version.h to dependency lists.
5660 (markers.o): Remove duplicate rule.
5662 * version.h: New file.
5664 * version.c: New file.
5666 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5668 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5669 array; use it appropriately. Since GCC is quite happy to
5670 subscript functions, it never warned us about this; we should use
5671 -Wpointer-arith in the future. I guess we never tested
5674 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5676 * socket.c: Doc and copyright fixes.
5678 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>

5682 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5684 * socket.c: Added declaration of inet_aton to avoid compiler
5685 warning. (Hope this solution is correct.)
5687 * stime.c: Added declaration of ftime. (This is missing in
5690 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5692 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5694 * Makefile.in (c_files): add strerror.c.
5696 * strerror.c: new file from Emacs' sysdep.c.
5697 maybe configure should also check for sys_errlist.
5699 * configure.in (AC_REPLACE_FUNCS): add strerror.
5701 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5703 * debug.c (scm_init_debug): Added initialization for
5704 scm_evaluator_traps.
5706 * debug.h, debug.c: Various name changes.
5707 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5708 "debug-options-interface". See commentary in options.c.
5710 * options.h, options.c: Options now have documentation strings.
5711 Also added a long explanatory commentary.
5713 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5716 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5717 last_debug_info_frame is now updated in all cases.
5719 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5722 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5724 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5725 Added option STACK_CHECKING.
5727 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5729 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5731 * __scm.h: Removed symbols for debugging support.
5733 * acconfig.h: Added symbols for debugging support.
5735 * configure.in: Added user option for debugging support.
5736 --enable-debug will include the debugging code into libguile.a.
5738 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5739 scm_relocate_chunk_to_heap.
5741 * debug.c: New file: low-level debugging support. It also
5742 includes support for debugging with gdb. (The extensions to gdb
5743 are written by Per Bothner at Cygnus.)
5745 * debug.h: New file: low-level debugging support.
5747 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5748 argument pairs. Extensive modifications to the debugging
5749 evaluator. Added "SECTION:" commentaries to clarify what happens
5750 when, during double compilation. Renamed EVALIMP --> EVALIM.
5751 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5752 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5753 the beginning of the file. New procedure: scm_unmemocopy.
5754 Added some global state variables needed by the debugging
5755 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5756 check_entry, check_apply, check_exit, debug_options and
5757 evaluator_traps. New acro: undefine.
5759 * eval.h: Renamed EVAL --> XEVAL.
5761 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5762 --> scm_make_weak_key_hash_table.
5764 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5765 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5767 * libguile.h: Conditionally include debug.h
5769 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5770 scm_object_properties shouldn't return handle. `handle' now gets
5771 initialized in scm_set_object_properties_x. scm_object_properties
5772 doesn't any longer create an entry in scm_object_whash.
5774 * options.c: New file: handling of run time options.
5776 * options.h: New file: handling of run time options.
5778 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5780 * print.c: New procedure: scm_print_options
5782 * print.h: Defines for print options.
5784 * read.c: New procedure: scm_read_options
5786 * read.h: Defines for reader options.
5788 * root.h: Added scm_source_whash among scm_sys_protects.
5790 * srcprop.c: New file: source properties.
5792 * srcprop.h: New file: source properties.
5794 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5795 (Bug found by A. Green.)
5797 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5799 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5801 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5803 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5805 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5806 and should be called by the final client.
5808 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5810 * gc.h: Use the PROTO macro when declaring functions.
5811 * gc.c: Use the PROTO macro when declaring static functions.
5812 Remove the CPP hair around function definitions.
5814 * gc.c (scm_init_storage): Initialize scm_asyncs.
5816 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5817 preprocessor symbol; "__scm.h" is where it might get #defined.
5818 * __scm.h: Similar: #include <scmconfig.h> before testing
5821 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5823 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5825 * init.c (scm_boot_guile): Add init_func argument; call
5826 (*init_func) instead of calling scm_appinit; it's ucky to
5827 hard-code names for the user's procedures.
5828 * init.h (scm_boot_guile): Adjust declaration.
5830 * __scm.h (PROTO): New macro, for declaring functions with
5833 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5834 eliminate all the __STDC__ conditionals.
5835 (scm_boot_guile): Add declaration.
5836 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5837 Remove __STDC__ conditionals around function definitions; the
5838 declarations in init.h will provide the same information, more
5841 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5842 complain about it in the error message; the error message is
5843 adequate without that note, and there's nothing the user can do
5846 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5848 * Makefile.in (ancillary): Drop def.sed.
5850 * posix.c (scm_init_posix): Use numeric values, rather than
5851 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5852 F_OK. The symbols aren't available on some systems, and I'm
5853 pretty sure their values are fixed by common widespread practice.
5854 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5856 More functions unavailable on some systems.
5857 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5858 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5860 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5861 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5862 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5863 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5864 stub that signals an error as the #else.
5866 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
5868 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
5870 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
5872 * unif.c: include ramap.h.
5874 * read.c (endif): case_insensative_p renamed case_insensitive_p.
5876 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
5878 * ports.c: include sys/ioctl.h.
5880 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
5882 * configure.in: check for sys/ioctl.h.
5884 * ports.c: include <malloc.h> not "malloc.h".
5886 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5888 * fports.c: remove ttyname and tmpnam declarations.
5890 * posix.c: fewer ttyname declarations.
5892 * fports.c: include <string.h> not "string.h".
5894 * init.c, ioext.c: include string.h and unistd.h.
5896 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5898 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
5899 genio.c, simpos.c, vports.c: include string.h.
5901 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
5903 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
5905 (scm_addr_buffer_size): change type from scm_sizet to int.
5906 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
5907 from scm_sizet to int.
5909 * error.c: include unistd.h.
5911 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
5914 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
5916 * __scm.hd, def.sed: deleted.
5918 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
5920 Changes for NeXT, suggested by Robert Brown.
5921 * configure.in: Call AC_TYPE_MODE_T.
5922 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
5923 NeXT. Put header file list in alphabetical order.
5924 * configure, scmconfig.h.in: Regenerated.
5925 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
5927 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
5930 * acconfig.h: New file, providing documentation for the CPP
5931 symbols defined in configure.in
5932 * acconfig-1.5.h: Removed; superceded by the above.
5934 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
5936 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
5938 * fports.c (scm_open_file): don't return #f, throw error.
5940 * ioext.c (fileno): renamed from %fileno.
5941 (soft-fileno): deleted.
5943 * ports.c (scm_port_revealed): don't need to check for -1 from
5945 (scm_set_port_revealed_x): return unspecified, not #f.
5947 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
5949 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
5951 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
5953 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
5955 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5957 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5958 This is necessary on Ultrix, and doesn't hurt portability.
5960 * Makefile.in (dist-dir): New target, implementing a new dist system.
5961 (installed_h_files): Put in alphabetical order.
5962 Remove duplicate entries for markers.h and unif.h.
5963 (c_files): Remove duplicate entries for markers.c.
5964 (ancillary): Renamed from anillery; all uses changed. Remove
5965 PLUGIN; it's a directory, and needs special treatment in dist-dir.
5966 Remove all the ../doc/* files; doc/Makefile.in handles that.
5968 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5970 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5971 every if must have an else, or else the whole command has a
5972 non-zero exit code whenever the if's condition is false.
5974 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
5976 * posix.c: include string.h.
5978 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
5980 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
5983 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
5984 Remove leading % from scheme names.
5985 Do not return error values, call SCM_SYSERROR or similar.
5987 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
5989 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
5991 * struct.c (scm_init_struct): new file.
5993 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
5995 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
5996 (scm_list_head): added list-head for rapidly chopping argument
5997 lists off of longer lists (and similar).
5999 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
6001 * objprop.c (scm_object_property): assq the cdr of the whash
6002 handle for obj, not the handle itself.
6004 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
6006 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
6007 weak hash tables last of all marking to avoid an obscure gc bug.
6008 WARNING: circular lists stored in a weak hash table will hose us.
6010 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
6012 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
6013 new functions similar to scm_substring_move_left_x and
6014 scm_substring_move_right_x.
6016 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
6018 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
6021 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
6023 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
6025 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
6027 * strports.c (scm_strprint_obj): convenience function. C for
6028 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
6030 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
6031 removed to a separate library
6033 * init.c (scm_boot_guile): copied from guile-tcl.c.
6034 Initialization specific to tcl interpreters removed.
6036 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
6038 * ports.c (scm_ports_prehistory): size malloced here doesn't
6039 matter so long as it is non-0 (got rid of "* 4").
6041 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
6043 * gscm.h: gscm_mkarray eliminated (presumably was not being used
6044 since its definition was bogus).
6046 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
6048 * mallocs.[ch]: back again (for rx at least).
6050 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
6052 * ports.c: removed functions relating to the mapping between ports
6053 and descriptors. (That stuff is unix-specific and should be collected
6054 in a separate library).
6056 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
6057 (Tom Mckay@avanticorp.com)
6059 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
6061 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
6062 handled correctly (SCM_FREEP was applied to them) -- test for
6063 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
6064 being overwritten with #f. (brown@grettir.bibliotech.com)
6066 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
6068 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
6069 for a specific symbol or for all symbols.
6071 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
6073 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
6074 keys and weak values confused).
6076 Thu Mar 14 22:20:20 1996 Tom Lord <lord@beehive>
6078 * list.c (scm_last_pair): map '()=>'()
6080 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>
6082 * pairs.c, hashtab.c, list.c, alist.c append.c, sequences.c:
6083 Generalized assoc and hash-table functions.
6084 Factored pairs.c into multiple files.
6086 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
6088 * gscm.c (gscm_run_scm): got rid of objprop.
6090 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
6092 * genio.c (scm_getc):
6093 NOTE: fgetc may not be interruptable.
6095 * procprop.c (scm_stand_in_scm_proc):
6096 NOTE: don't use a alist here.
6097 (scm_set_procedure_properties_x): fix type checking throughout this file.
6099 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
6101 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
6102 after freeing part of the port table.
6104 Thu Feb 29 16:21:17 1996 Tom Lord <lord@beehive>
6106 * strports.c (scm_mkstrport):
6107 * vports.c (scm_make_soft_port): allocate a port table entry
6108 (possibly triggering gc) before setting the tag of the corresponding
6111 * pairs.c (scm_delq_x): never throw an error.
6113 * vectors.c (scm_make_vector): made the default vector fill argument
6114 into '() (much more useful than the previous value, "#unspecified")
6116 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
6118 * ports.c (scm_add_to_port_table): Added fields
6119 to port table entries: file_name, line_num, col.
6120 Update these in open_file, gen_getc and gen_ungetc.
6121 Added procedures to access those fields.
6123 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
6125 * procs.c (scm_make_subr_opt): new entry point for making
6128 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
6130 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
6132 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
6134 * numbers.c (scm_exact_p): This function no longer
6135 implements "integer?".
6137 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
6139 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
6140 (scm_gc_stats): return an assoc of useful data. Replaces "room"
6141 and the stats reporting formerlly built into repl.
6143 * repl.[ch]: removed.
6144 GC statistics keeping moved to gc.c.
6145 Other statistics keeping can be done from Scheme.
6146 REPLS are now written in Scheme.
6148 Wed Feb 21 10:28:53 1996 Tom Lord <lord@beehive>
6150 * cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky
6151 conservatively marked objects).
6153 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
6155 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
6157 * feature.c (scm_compiled_library_path): moved here from repl.c.
6158 This file is for stuff relating specifically to Scheme libraries
6161 * eval.c (scm_m_define): don't give warning about redefinition, don't
6164 NOTE: this should throw a resumable exception with parameters --
6165 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
6167 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
6169 * error.c: scm_warn eliminated.
6171 * read.c (scm_lreadr): extra right paren gets an error, not a warning.

6174 lose exit_report, growth_mon.
6176 * gscm.c: got rid of verbosity functions.
6178 Tue Feb 20 00:19:10 1996 Tom Lord <lord@beehive>
6180 * throw.c (scm_ithrow): guard against the bad-throw hook changing
6181 between the call to procedurep and use.
6183 * error.c (scm_everr):
6185 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
6188 * strports.c: don't reveal the port's string to the caller
6189 because it changes size.
6191 (stputc stwrite): check/change the strings length with interrupts
6194 * objprop.c (scm_set_object_property_x &c): use the generic
6195 hashing functions and be threadsafe.
6197 * eval.c (scm_unmemocar): do this operation in a thread-safe way.
6198 (per suggestion jaffer@gnu.ai.mit.edu).
6200 * mbstrings.c (scm_multi_byte_string): guard against argument list
6203 * strings.c (scm_make_string): loop cleanup
6205 * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer
6208 * weaks.c (scm_weak_vector): guard against argument list
6211 * variable.c (scm_builtin_variable): check for/make a built-in
6214 * vectors.c (scm_vector): while filling the new array,
6215 guard against a list of fill elements that grows after
6216 the vector is allocated.
6218 * hashtab.c -- new file: general hash table
6219 functions. hash, hashq, hashv, hashx.
6221 * tags.h: made wvect an option bit of vector.
6223 Mon Feb 19 09:38:05 1996 Tom Lord <lord@beehive>
6225 * symbols.c: made the basic symbol table operations atomic.
6227 * root.c &c.: collected stack-specific global state.
6228 linum/colnum etc *should* be port-specific state.
6230 * struct.c (scm_init_struct): init the first struct type during
6231 initialization to fix a race condition.
6233 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
6234 object, not in a global.
6235 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
6237 * throw.c (_scm_throw): Pass throwval on the stack, not in a global
6238 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
6240 * *.[ch]: namespace cleanup. Changed all (nearly) exported CPP
6241 and C symbols to begin with SCM_ or scm_.
6243 Sun Feb 18 15:55:38 1996 Tom Lord <lord@beehive>
6245 * gsubr.c (scm_gsubr_apply): statically allocate the
6246 array of arguments (bothner@cygnus.com).
6248 Sat Feb 17 20:20:40 1996 Tom Lord <lord@beehive>
6250 * scmsigs.c: Simplified to use async rountines.
6252 * async.c: New support for interrupt handlers.
6254 Thu Feb 15 11:39:09 1996 Tom Lord <lord@beehive>
6256 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
6257 set the multi_byte flag correctly in symbols. This is wrong.
6258 intern_obbary_soft and msymbolize should take an extra parameter.
6259 Also, weird multibyte symbols don't print correctly.
6260 The weird symbol syntax is also a bit bogus (emacs doesn't quite
6263 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
6265 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means
6266 use the system symhash. == #t means create an uninterned symbol.
6268 Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>
6270 * strings.c (scm_make_shared_substring): build'em.
6271 It might better to keep a table of these and use one
6272 less cons-pair per shared-substring.
6274 Tue Feb 6 17:45:21 1996 Tom Lord <lord@beehive>
6276 * strings.c (scm_string_shared_substring): create shared
6277 substrings. (Doesn't handle mb strings yet).
6279 * mbstrings.c (scm_print_mb_string): handle RO strings.
