1 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
4 declarations. (Thanks to Russ McManus.)
6 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
8 * numbers.c (num2long): As a software archeologist, I'm proud of
9 this finding! :) Preliminary dating suggests an almost 4 year old
10 remnant from the SCM ancestor. The sample has been removed from
11 the finding site and is now safely stored in the repository.
13 * numbers.h: Removed prototype for num2long.
15 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
17 * gh_data.c (gh_scm2doubles): Make it possible to pass result
19 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
20 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
21 * gh.h: Updated and added prototypes.
23 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
25 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
27 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
29 * guile-snarf.in: Never generate an empty file. (Thanks to
32 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
33 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
34 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
35 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
36 gh_new_procedure5_0): Specify argument types, to appease C++
37 compilers. (Thanks to Brad Bowman.)
39 Bug reports from Russ McManus:
40 * guile-snarf.in: If the CPP environment variable is set, use that
41 as the C preprocessor, instead of the preprocessor autoconf
43 * snarf.h (SCM_PROC): Cast the function pointer passed to
44 scm_make_gsubr, to satisfy C++.
46 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
47 Use the handler passed, instead of ignoring it and using
48 gh_standard_handler. (Thanks to Etienne Bernard.)
50 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
52 * ports.h: Put text after #endif in comment. (Thanks to Nicolas

72 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
75 * script.c (scm_compile_shell_switches): Define
76 use-emacs-interface in the root module, so the repl code can see
77 it. See today's change to top-repl in ice-9/boot-9.scm.
79 * filesys.c (set_element, get_element): Make sure that `element'
80 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
81 Boekemeier and Jorgen "forcer" Schaefer.)
83 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
85 * chars.c (scm_charnames): In ASCII character name table, make
86 newlines print as #\newline by default, not #\nl.
88 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
89 alphabetical order. Oh thrills. But it helps me know how far
90 along in the compilation I am.
91 * Makefile.in: Regenerated.
93 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
95 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
96 #bytes(...) to #y(...), and syntax for short vectors from
97 #short(...) to #h(...). This may seem nutty, but, like the other
98 uniform vectors, byte vectors and short vectors want to have the
99 same print and read syntax (and, more basic, want to have read
100 syntax!). Changing the read syntax to use multiple characters
101 after the hash sign breaks with the conventions used in R5RS and
102 the conventions used for the other uniform vectors. It also
103 introduces complexity in the current reader, both on the C and
104 Scheme levels. (The Right solution is probably to change the
105 syntax and prototypes for uniform vectors entirely.)
107 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
109 Don't use local_fgets on sockets; ftell doesn't work on sockets.
110 (Thanks to Jorgen "forcer" Schaefer.)
111 * ports.h (SCM_NOFTELL): New flag.
112 * fports.c (local_fgets): If it's set, use the generic fgets.
113 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
115 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
117 * script.c (scm_compile_shell_switches): Add handling of -q switch
118 (inhibit loading of user init file).
119 (scm_shell_usage): Add usage text for -q switch.
120 (scm_compile_shell_switches): Always load user init file first if
123 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
125 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
126 and is now broken under NetBSD. I can't fathom what it's trying
127 to do, so I've replaced it with something that I do understand,
128 which seems to work, and which isn't broken on NetBSD. "Progress?
129 You Decide." (Thanks to Perry Metzger.)
131 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
132 signed/unsigned comparison.
134 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
136 Warning fixes from Greg Harvey:
137 * unif.c (scm_array_set_x): initializer for pos
138 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
139 * struct.c (scm_struct_ref, scm_struct_set_x): Added
140 initializers for field_type, since EGCS so desparately wants to
142 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
143 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
144 when GUILE_DEBUG is defined.
145 * dynwind.h (scm_wind_chain): Same.
146 * ports.h (scm_pt_size, scm_pt_member): Same.
147 * print.h (scm_current_pstate): Same.
148 * procs.h (scm_make_cclo): Same.
150 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
152 Handle short and long long uniform arrays properly. (Thanks to
154 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
155 raeql_1): Add cases for scm_tc7_svect (short vectors) and
156 scm_tc7_llvect (long long vectors).
158 Change the way libguile and boot-9.scm are timestamped, to try to
159 get rid of these spurious mismatch warnings. Now both
160 libguile/versiondat.h and ice-9/version.scm are generated directly
161 by the configuration process, rather than having version.scm
162 generated directly, and libguile/versiondat.h generated by the
163 Makefile, which is generated by configure. It seems that
164 sometimes the Makefile would change, but versiondat.h depends on
165 Makefile.in, not Makefile, so it wouldn't get rebuilt.
166 * Makefile.am (versiondat.h): Target removed; this is generated
167 directly by the configure script now.
168 (BUILT_SOURCES): Remove versiondat.h.
169 * versiondat.h.in: New file, transformed by the configure script
171 * Makefile.in: Regenerated.
173 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
174 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
175 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
176 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
177 if we want to use them in a header file some day, we can. (Thanks
180 * stime.c (scm_get_internal_real_time): Do the arithmetic using
181 SCM numbers, so we won't have rollover problems; the range of a
182 signed long in milliseconds is about 25 days. (Thanks to Karl
185 Don't redefine sleep and usleep; fix this problem now.
186 * coop.c (sleep, usleep): Remove declarations; we don't use or
187 redefine these any more.
188 (scm_thread_usleep, scm_thread_sleep): New functions which do the
189 job of usleep and sleep in a thread-friendly way. We can use
190 these in the rest of Guile. Define versions for systems both with
192 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
193 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
194 we're just using it, not redefining it, we can use a K&R style
196 (sleep): Declare this, too, if the system hasn't.
197 (scm_sleep, scm_usleep): Use scm_thread_sleep and
198 scm_uthread_sleep if they're available; otherwise, just call the
200 * scmconfig.h.in: Regenerated.
202 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
204 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
206 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
208 * threads.c: Doc fix.
210 The argument type of usleep varies from system to system,
211 as does the return type. We really shouldn't be redefining usleep
212 at all, but I don't have time to clean that up before the 1.3.
213 release. It's on the schedule for afterwards. (Thanks to Julian
215 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
217 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
218 * scmconfig.h: Regenerated.
220 * simpos.c (scm_software_type): Procedure deleted. This isn't the
221 right way to handle system variation. Autoconf's approach is the
223 * simpos.h (scm_software_type): Declaration deleted.
225 * script.c (scm_find_executable): Don't test if unix is #defined
226 here; first, NetBSD doesn't #define it, and second, it's the wrong
227 way to go about these things. (Thanks to Perry Metzger.)
228 (dld_find_executable): Delete this MSDOS support code. This isn't
229 the way we want to support this; it needs to be rethunk at a
232 * genio.c (scm_do_read_line): Don't just politely check that the
233 line was either non-empty or EOF. Abort if it's empty and not
236 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
238 * scmconfig.h.in: Regenerated.
240 * libguile.h: Don't omit the dynamic linking functions. (Thanks
243 * genio.c (scm_do_read_line): Count lines correctly when the file
244 doesn't end in a newline.
246 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
248 * genio.c (scm_do_read_line): Maintain the line count correctly.
249 (Thanks to Harvey J. Stein and Greg Harvey.)
251 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
254 * numbers.c (big2str): Protect t from garbage collection until
255 we're done. (Thanks to Gary Houston.)
257 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
259 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
261 * Makefile.in: Regenerated.
263 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
264 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
267 Do magic to mix reads and writes on stdio FILE-based ports.
268 (Thanks to Christian Lynbech.)
269 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
271 (pre_read, pre_write): New functions.
272 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
273 local_fputs): Call them.
274 (local_fflush): Mark the port as ready for reading and writing.
275 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
276 flags on new port objects. This might not be accurate --- who
277 knows what state the FILE * is in when we get it --- but it won't
278 do extraneous calls to fflush or fseek, so it's no worse than the
279 behavior before this change.
280 * ports.h: Add comment.
282 Centralize the creation of port objects based on stdio FILE * in
283 fports.c; don't just throw them together anywhere.
284 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
285 what the rest of Guile wants. Don't set the revealed count;
286 that's only appropriate for stdin, stdout, stderr.
287 (scm_standard_stream_to_port): This function does set the revealed
289 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
290 not scm_stdio_to_port.
291 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
292 * fports.c (scm_open_file): Same.
293 * posix.c (scm_pipe): Same.
294 * socket.c (scm_sock_fd_to_port): Same.
295 * ioext.c (scm_fdopen): Same.
296 (scm_freopen): Moved from here to...
297 * fports.c (scm_freopen): ... here. This is really something that
298 munges the internals of an fport, so it should go here.
299 * fports.h (scm_stdio_to_port): Adjust prototype.
300 (scm_standard_stream_to_port, scm_freopen): New protoypes.
301 * ioext.h (scm_freopen): Prototype removed.
303 * filesys.c (set_element, get_element): This can work on both pipe
304 and file ports, so use SCM_FPORTP to typecheck, instead of testing
307 * scmconfig.h.in: Regenerated.
309 Change the definition of the functions in scm_ptobfuns so that
310 they get passed the port object, not the port's stream.
311 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
312 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
313 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
314 Pass the port itself to the scm_ptobs function.
315 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
316 scm_generic_fgets): Same.
317 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
318 getc_void_port, fgets_void_port, close_void_port): Just change the
319 argument names; these functions don't really do anything.
320 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
321 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
322 port as an argument, and use SCM_STREAM to get the stdio FILE *.
323 Also, use prototyped definitions, and get rid of the extra
325 (scm_fptob, scm_pipob): We don't need casts here any more.
326 * strports.c (prinstpt): Use prototype declarations.
327 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
328 and use SCM_STREAM to get the string info. Also, use prototyped
329 definitions, and get rid of the extra declarations.
330 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
333 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
334 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
336 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
337 scm_fgets, for consistency.
338 (scm_fptop, scm_pipob): References updated.
340 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
342 Include the source location in error messages for scripts.
343 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
344 stack is still there when we catch the error.
345 * throw.c (handler_message): If we are handling an error with a
346 message, then put together the proper arguments and call
347 scm_display_error, instead of scm_display_error_message. That
348 displays source location, if it can find it.
350 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
352 * gc.c (scm_unprotect_object): Change this so that calls to
353 scm_protect_object and scm_unprotect_object nest properly.
354 (scm_protect_object): Doc fixes.
356 * strings.c (scm_string_set_x): Require the argument to be a
357 writable string, not a substring or a symbol.
358 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
359 (Thanks to John Redford and Charbel Jacquin.)
361 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
363 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
365 * eval.c (safe_setjmp): Remove this misunderstanding.
366 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
369 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
371 * libguile.h: Mark these as C declarations, for compilation by C++
374 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
375 __cplusplus clause. I seriously doubt this ever worked the way
376 the author seems to have intended.
378 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
380 Utterly needless cleanups to hopelessly messy code.
381 * ports.c: Doc fixes.
382 (scm_fflush): Moved to ...
383 * genio.c (scm_fflush): ... here, amongst all the other port
384 method invocation functions.
385 * genio.h, ports.h: The prototype moves too.
387 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
389 * backtrace.c (display_error_body): The current frame does not
390 always have a parent frame; consider a function called directly
391 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
394 * alloca.c (alloca): Undo yesterday's changes, and simply call
395 malloc directly for storage, and abort if we don't get what we
396 want. The situation is much simpler --- just call malloc. Emacs
397 has bizarre/evil requirements (signal handlers might malloc unless
398 you set this global flag, so you have to set the flag around all
399 calls to malloc) which we are certainly not going to conform to,
400 so we can do the simple and obvious thing.
402 * coop.c (coop_condition_variable_wait): Make this function
403 static. It's only useful internally --- you should never just
404 wait on a condition variable.
405 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
407 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
409 * unif.c (scm_array_set_x): Accept any kind of number as an
410 element for a uniform vector of doubles. This is more consistent
411 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
413 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
414 works; I can't conveniently test it myself. (Thanks to Dvid
415 Tillman for the bug report.)
419 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
420 from here, not from scm_compile_shell_switches (which is a pretty
421 dumb place to do it).
422 (scm_load_startup_files): New function.
423 (scm_ice_9_already_loaded): Variable moved to here from script.c.
424 * script.c (scm_compile_shell_switches): Don't load the startup
426 (scm_ice_9_already_loaded): Variable moved.
427 * init.c (scm_load_startup_files): Prototype for new function.
428 * gh_init.c (gh_enter): Doc fix.
430 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
432 Some anti-warning changes from Greg Harvey.
433 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
434 warnings when it doesn't understand our NORETURN declarations in
436 * posix.c (scm_mknod): Similar.
438 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
440 * posix.c (scm_getpwuid): If we can't find an entry, return our
441 own message, instead of using scm_syserror --- the getpwMUMBLE
442 functions don't set `errno' to anything interesting.
444 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
446 Get rid of warnings from the cooperative threading system.
447 * threads.h (scm_single_thread_p, scm_yield,
448 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
449 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
450 scm_wait_condition_variable, scm_signal_condition_variable): Add
451 prototypes for these Scheme-visible functions.
452 * coop-defs.h (coop_next_runnable_thread,
453 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
454 Prototypes for these here, even though they're from iselect.c.
455 (coop_condition_variable_wait, coop_join): Add prototypes.
456 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
457 scm_threads_free_condvar): Make these smob functions static.
458 * coop-threads.h (coop_init): Give this a real prototype.
459 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
460 (coop_next_runnable_thread): No need to provide prototype; it's in
463 * scmconfig.h.in: .detarenegeR
465 * iselect.c, threads.c: Doc fixes.
467 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
469 * Makefile.in: Regenerated with a patched automake, to get
470 dependency generation right when using EGCS.
472 * inet_aton.c (inet_aton): Add prototype, to remove compiler
473 warning. (Thanks to Robert Pluim.)
475 * inet_aton.c (inet_aton): Reassure the compiler that the
476 arguments to the <ctype.h> macros are all unsigned characters, not
479 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
481 Getting rid of more warnings...
482 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
483 today's change to ../configure.in.
484 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
485 * scmconfig.h.in: Regenertaded.de.,.__
486 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
487 (scm_localtime, scm_mktime): Use a const char * to manipulate the
490 * readline.c: Doc fix.
491 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
492 * readline.h (scm_filename_completion_function): Add prototype.
493 (scm_init_readline): Make this into a prototype.
495 * readline.c (scm_filename_completion_function): Use SCM_PROC to
496 declare this, instead of calling scm_make_subr manually.
498 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
500 * readline.h (scm_init_readline): Add prototype for this.
501 (scm_init_readline): Make this a real prototype.
503 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
505 Warning fixes from Maciej Stachowiak:
506 * backtrace.h (scm_display_application, scm_backtrace): Add
508 * debug.c (scm_m_start_stack): Make this function static.
509 * fluids.h (scm_fluid_p): Add prototype.
510 * procprop.c (scm_i_procedure_arity): Make this function static.
511 * regex-posix.c (scm_regexp_error_msg): Make this function static.

513 * root.h (scm_dynamic_root): Add external prototype.
514 * scmsigs.h (scm_usleep): Add external prototype.
515 * script.h (scm_init_script): Use prototype, not K&R decl.
516 * stacks.h (scm_stack_id): Add external prototype.
517 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
519 1998-09-30 Mark Galassi <rosalia@cygnus.com>
521 * gh.h: took out the definitions of vset and vref, since they are
522 replaced by the proper vector routines that correspond to the R4RS
525 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
527 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
528 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
529 third argument, a C expression that should result in a SCM value,
530 which is used to initialize the variable. Reimplemented
531 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
534 * version.h (scm_libguile_config_stamp): Add prototype.
535 (From Maciej Stachowiak.)
537 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
539 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
540 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
542 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
544 * print.c (scm_iprin1): Rather than having one i, and using it in
545 several places, declare a fresh i local to each block where it is
546 used, and give it a signedness appropriate to its use in each case.
549 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
552 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
553 signed/unsigned clashes.
555 * posix.h (scm_tmpnam): Added prototype.
557 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
558 scm_make_subclass_object): Add external prototypes.
560 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
561 comparison is okay here.
563 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
565 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
566 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
568 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
571 * load.c (swap_port): Make this function static.
573 * load.c (scm_search_path): Make max_path_len and max_ext_len
574 unsigned, since they're compared against string sizes.
576 * load.c (init_build_info): Make i unsigned.
578 * ioext.h (scm_read_line): Add prototype.
580 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
581 scm_hash_fn_remove_x): Make hash bucket index local variable k
582 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
583 accurately as possible.
585 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
586 comparisons, and range checking to make sure those casts are
589 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
590 signed/unsigned comparisons.
592 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
593 avoid signed/unsigned comparisons.
594 * smob.h (scm_numsmob): Change extern declaration to match.
596 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
597 avoid signed/unsigned comparisons.
598 * ports.h (scm_numptob): Change extern declaration to match.
599 (scm_current_load_port, scm_set_port_line_x,
600 scm_set_port_column_x): New prototypes.
602 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
603 test code, and it causes warnings.
605 * gh.h (gh_int2scmb, gh_uniform_vector_length,
606 gh_uniform_vector_ref): Added prototypes.
608 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
609 debugging support unconditionally. That's backtrace.c, stack.c,
610 debug.c, and srcprop.c.
611 (EXTRA_libguile_la_SOURCES): Omit those from here.
612 * Makefile.in: Regenerated.
614 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
616 * options.c (scm_options): Bugfix: Allow empty list of options!
618 * debug.c, debug.h (scm_single_step): Removed.
619 (scm_with_traps): New procedure. This procedure could easily be
620 written in Scheme but needs to be highly optimized.
622 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
624 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
625 Check SCM_TRAPS_P before trapping.
627 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
629 Changes to avoid signed/unsigned comparison warnings.
630 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
631 (scm_gc_sweep): Make n and j local to the blocks they're used in,
632 so they can have appropriate types for each application. Make i
633 signed. Use initializers in some spots. I'll probably pay for
635 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
636 (scm_must_realloc): Make nm unsigned.
637 (init_heap_seg): Make new_seg_index and n_new_objects signed.
638 (scm_init_storage): Use prototype-style definition, and make the
640 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
641 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
643 * filesys.c (scm_readlink): Make local vars rv and size ints, to
644 avoid signed/unsigned comparison warnings, and because the return
645 value of readlink may be -1. Don't bother casting the third
646 argument to readlink.
648 * filesys.c (scm_dirname, scm_basename): Move these to their own
649 page, at the end of the file.
650 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
652 * eval.h (scm_eval_options_interface): Add external prototype for this.
653 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
655 * eval.c (scm_lookupcar1): Make this static.
657 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
658 Make these prototype declarations, not K&R-style.
660 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
661 unsigned comparison warning.
663 * appinit.c: File removed. It had a single function in it, empty,
664 whose reason for existence is explained in no documentation or
665 comment. I think it's there as a default for some Tcl-style
666 initialization, but Tcl abandoned that approach a while ago.
667 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
668 (BUILT_SOURCES): Remove appinit.x.
669 * Makefile.in: Regenerated.
671 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
673 * Makefile.in: Regenerated using the last public version of
674 automake, not the hacked Cygnus version.
676 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
678 Remove Totoro kludge.
679 * Makefile.in, scmconfig.h.in: Regenerated.
680 * init.c, readline.c: Don't check if TOTORO is #defined.
682 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
684 * Makefile.am: Adjust for new thread configuration system.
685 (INCLUDES): Include the value of THREAD_CPPFLAGS.
686 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
688 (THREAD_LIBS): Definition deleted; automake will generate such
689 things automatically.
690 * Makefile.in: Regenerated.
692 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
694 Simplify smob and port marking; set the mark bit in the generic
695 marking code, and make marker routines only responsible for
696 turning up outgoing pointers.
697 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
698 before calling the marking function. Don't call the marking
699 function if it's zero.
700 * markers.c (scm_mark0): Just return #f. This function isn't
701 necessary at all now, but it's harmless to call it. We'll leave
702 it in so other folks' code doesn't croak at link time.
703 (scm_markcdr): Don't call SCM_SETGC8MARK.
704 * async.c (mark_async): Don't call SCM_SETGC8MARK.
705 * dynl.c (mark_dynl_obj): Same.
706 * root.c (mark_root): Same.
707 * srcprop.c (marksrcprops): Same.
708 * unif.c (markra): Same.
709 * variable.c (scm_markvar): Same.
710 * ports.c (scm_markstream): Same.
711 (void_port_ptob): Specify zero for our marking function.
712 * debug.c (debugobjsmob): Same.
713 * dynwind.c (guardsmob): Same.
714 * filesys.c (dir_smob): Same.
715 * fluids.c (fluid_smob): Same.
716 * fports.c (scm_fptob, scm_pipob): Same.
717 * mallocs.c (mallocsmob): Same.
718 * regex-posix.c (regex_t_smob): Same.
719 * smob.c (freecell, flob, bigob): Same.
720 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
721 * throw.c (jbsmob, lazy_catch_funs): Same.
723 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
725 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
726 scm_copy_tree on code in order not to let memoized code to leak
727 out. Thus, scm_copy_tree needs to copy vectors as well since
728 quasiquote can introduce evaluated code also inside vector
731 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
733 * eval.c (scm_copy_tree): Removed ability to copy vectors.
735 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
736 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
739 * unif.c: Say that ivect and uvect are of type signed and unsigned
740 long instead of int in commentary so that it correctly describes
743 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
745 * stime.c: Removed declaration of strptime. (It should be
746 declared by the system headers. If it turns out that some systems
747 don't, we'll handle that then.) (Thanks to Greg Troxel.)
749 * stime.h: Renamed TIMEH --> STIMEH
751 * backtrace.c (scm_display_error, scm_display_backtrace): In order
752 to increase portability, don't use structure assignment.
753 (Thanks to Nicolas Neuss.)
755 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
757 (finalize_fd_sets): Added empty statement after last case label.
758 (Thanks to Nicolas Neuss.)
760 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
763 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
765 * init.c, readline.c: OK, I won't have these readline.x bug
766 reports anymore. We've had them since April. The current reason
767 is a completely unintelligible failure of totoro.red-bean.com to
768 do the test for rl_getc_function in libreadline correctly. This
769 kludge overrides the test if we're on totoro so that the snapshot
770 generation process can work.
772 * readline.c: Define a strdup replacement if not existent on system.
774 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
776 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
777 This change makes scm_make_vector R5RS compatible. We cannot keep
778 the third argument since people want to be able to deduce the form
779 of the C function call only by looking at R5RS. (At the same time
780 we have removed some unnecessary complexity!)
782 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
783 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
784 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
785 argument in call to scm_make_vector.
787 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
789 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
790 This macro is useful in applications.
792 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
794 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
795 (scm_parse_path, scm_search_path): New Scheme level procedures.
797 * load.h (scm_internal_parse_path, scm_parse_path,
798 scm_search_path): Declared.
800 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
802 * filesys.c (dirname, basename): New procedures.
804 * init.c (scm_boot_guile_1): Removed condition around
807 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
808 new data type (guards) for representation of C level guards and
809 data on the wind chain.
810 (scm_internal_dynamic_wind): New function.
812 * dynwind.h: Declare scm_internal_dynamic_wind.
814 * root.h (scm_root_state): Added scm_cur_loadp.
816 * root.c (mark_root): Added comment about cur_loadp.
818 * load.c: #include "dynwind.h";
819 (scm_primitive_load): Use scm_inner_dynamic_wind to update
822 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
824 * ports.c (current-load-port): New procedure.
826 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
828 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
829 not a tty, return #f.
831 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
832 to Julian Satchell and Roland Kaufmann.)
834 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
835 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
837 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
839 * debug.h, debug.c (scm_start_stack): New function. Implements
840 the guts of old scm_m_start_stack.
842 * debug.c (scm_m_start_stack): Use scm_start_stack.
844 * init.c (scm_start_stack, scm_restart_stack): Renamed to
845 start_stack and restart_stack. (These have static scope.)
847 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
849 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
850 readline functions to come in release 2.3. (Thanks to Chet
852 (handle_errors): Use the above functions.
854 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
856 * readline.c: Improvements for readline support: Handle errors
857 better; Implement before-read-hook.
859 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
861 * init.c (scm_boot_guile_1), readline.c: Test for
862 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
863 assure that we have version >= 2.1.)
865 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
867 * readline.c (scm_readline): Defer interrupts while we're calling
870 * readline.c (scm_add_history): Bugfix: Do strdup before giving
871 away the string to add_history.
872 (completion_function): Do completion for readline. (Thanks to
874 (scm_filename_completion_function): New procedure: Filename
876 (current_input_getc): New function. Use this one instead of
877 standard getc from readline.
879 * throw.c, throw.h (scm_handle_by_throw): New function: This
880 handler throws errors to next handler on the dynwind chain.
882 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
884 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
887 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
889 * procprop.c (scm_i_procedure_arity): New function. Returns arity
891 (scm_procedure_properties): Modified to return arity together with
893 (scm_procedure_property): Added the read-only property `arity'.
894 (scm_set_procedure_property_x): It is an error to set the `arity'
897 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
898 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
900 * procprop.h (scm_sym_arity): New symbol.
902 * objects.c (scm_set_object_procedure_x): New procedure: Use this
903 to set the dispatch procedure of an operator or entity object.
905 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
906 Made procedure slots read-only.
908 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
909 scm_tcs_cons_gloc case in zero args switch; Fixed args
910 construction for operators in scm_tcs_cons_gloc case in two args
913 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
915 * fluids.c: Removed use of assert.h (in order to avoid
918 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
920 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
922 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
923 change makes the evaluator safer at the cost of evaluation speed.
924 It handles the case when the user has added a non-immediate
925 improper end of the application form, e.g., `(+ 0 . x)'.
926 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
927 minimize the extra cost as much as possible. The new code is
928 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
929 problem with structs planted directly in the code (e.g. by a
930 macro). This no longer causes segmentation fault. (Thanks to
933 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
934 arg `proc' in order to be able to throw errors; New argument
937 * Removed extra #include "debug.h"
939 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
941 * scmsigs.c: Declare usleep as returning void on some systems.
942 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
945 * coop.c (usleep): Return void on some systems.
947 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
949 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
951 * coop.c: Changed return type of usleep to int.
953 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
954 isn't found in the OS.
956 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
957 isn't enabled. (Thought that I had made this change ages ago...)
959 * iselect.c: Declare bzero if not defined by OS.
961 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
963 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
964 condition. (Thanks to John Tobey.)
966 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
967 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
970 * __scm.h: Start the long-term project of moving to POSIX threads.
971 Phase 1: Classification of all critical sections.
972 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
973 for A sections. (See comments in __scm.h for details.)
975 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
976 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
978 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
980 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
981 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
982 (libpath.h, versiondat.h): Replaced dependency on Makefile with
983 dependencies on $(srcdir)/Makefile.in
984 $(top_builddir)/config.status in order to avoid circularity.
986 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
987 from argc if argc was 0 initially.
989 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
990 in generation of libpath.h.
992 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
994 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
995 libguile from 2 to 3.
997 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
999 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
1001 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
1003 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
1004 scm_set_port_column_x, scm_port_filename,
1005 scm_set_port_filename_x): Removed optional arguments. Added
1006 proper argument checking.
1008 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
1009 stack size in machine words.
1011 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
1012 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
1013 to Ole Myren Röhne.)
1015 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
1017 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
1018 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
1020 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
1023 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
1024 procedure apply: Copy argument lists before pushing them unto the
1025 environment so that the environment won't get mutated due to
1026 manipulation of procedure arguments. This should perhaps be
1027 regarded as a temporary solution until someone finds a more
1028 efficient one. (Thanks to Maciej Stachowiak.)
1030 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
1032 * script.c (scm_compile_shell_switches): Use "guile" as default
1033 zero arg if argc is NULL.
1035 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
1037 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
1038 is zero. (Thanks to Dirk Herrmann.)
1040 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
1042 * ports.c (scm_add_to_port_table): First line is now line 0
1043 (was 1). (Interface changed according to suggestion by Per
1046 * backtrace.c (display_header): Add 1 to line and column numbers
1047 when presenting them to the user.
1049 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
1050 from debug.c --> eval.c
1052 * eval.h, eval.c (scm_eval_options_interface): New options
1054 (SCM_EVAL_STACK): New option: Size of newly created stacks,
1055 i.e. stacks for new threads.
1057 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
1059 * eval.c (unsafe_setjmp): Removed with #if 0.
1061 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
1064 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
1065 to avoid compiler warnings.
1067 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
1069 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
1071 * throw.c (handler_message): Print message on current error port
1072 instead of default error port. (Thanks to Maciej Stachowiak.)
1074 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
1076 * ports.c (scm_add_to_port_table): allocate in units of
1077 struct scm_port_table *, not struct scm_port_table.
1078 * posix.c (scm_close_pipe): remove the port from the port table
1080 Thanks to Rob Engle for both fixes.
1082 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1084 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
1085 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
1087 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1089 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
1091 * backtrace.c (display_error_body, display_backtrace_body),
1092 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
1093 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
1094 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
1095 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
1098 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
1099 don't receive the jmpbuf arg anylonger.
1100 (scm_catch): Don't accept a #f tag.
1101 (scm_throw): Check that key is a symbol.
1102 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
1104 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
1106 * async.c (async_pending): Removed declaration.
1108 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1110 * dynwind.c (scm_wind_chain): New debug function.
1112 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
1113 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
1114 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
1115 extra layer of functions around the body and handler of a thread.
1116 This extra layer makes sure that the handler is called in the
1117 dynamic context of the surround (= empty dynwind list), but under
1118 the *dynamic root* of the body. We can not use the dynamic root
1119 of the surround since that root belongs to another thread => stack
1120 is not handled correctly. It may seem ugly to use this extra
1121 layer, but the extra cost in terms of execution time is really
1122 negligible compared to the total amount of time required to create
1123 a thread, and it would reduce maintainability to duplicate the
1124 crucial and complicated steps performed by cwdr.
1126 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
1127 (SCM_ALLOW_INTS): Added thread switching code before interrupts
1128 get re-enabled. The important effect of this is that interrupts
1129 are blocked during thread switching so that thread data structures
1130 don't risk getting messed up by an unfortunate signal.
1131 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
1132 seems to do more aggressive optimization which actually move
1133 instructions around in these macros in a fatal way. Therefore:
1134 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
1135 just superstitious...)
1136 (SCM_TICK): Maybe do a context switch and take care of asyncs.
1137 This macro should be used instead of SCM_ASYNC_TICK since the
1138 latter doesn't do context switches any more.
1140 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
1141 instead of SCM_ASYNC_TICK.
1143 * coop.c, iselect.c: Since thread switches are now performed with
1144 interrupts masked, we can't use the old mechanism of delivering
1145 signals immediately when they arrive. Signals must instead be
1146 delivered when the asyncs run *after* the end of the critical
1147 section in scm_internal_select. But this also means after context
1148 switch so that the signal will be delivered to a different thread.
1149 To avoid this, I have changed the protocol of
1150 coop_wait_for_runnable_thread and friends so that they are allowed
1151 to return the original thread. So, if a signal arrives during
1152 scm_internal_select, we won't any longer be forced do a context
1153 switch, but can remain in the same thread and deliver the signal
1156 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
1157 scm_asyncs_pending and made it global.
1159 * iselect.c: Small fixes.
1161 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
1162 coop_condition_variable_init, coop_condition_variable_wait,
1163 coop_condition_variable_signal): Changed return type from `void'
1164 to `int'. This is to adhere closer to the pthreads interface.
1165 This, in turn, is part of an attempt to provide C versions of the
1166 mutex and condition variable primitives which can be part of a
1167 frontend to COOP or pthreads.
1169 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
1170 coop_condition_variable_destroy): New functions.
1172 * coop-threads.c (scm_wait_condition_variable): Use
1173 coop_condition_variable_wait_mutex.
1175 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
1176 Definitions moved to coop-defs.h.
1178 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
1179 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
1180 scm_cond_destroy): New C interface to mutecis and cond vars.
1182 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1184 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
1186 * iselect.c: Now several threads can wait on the same file
1187 descriptor. The behaviour is compatible with OS select: All
1188 threads waiting for the fd return with the same status.
1190 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1192 * coop-threads.c, threads.h (scm_spawn_thread): New function.
1193 Can spawn a thread from application C code.
1195 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1197 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
1198 gh_doubles2scm): New functions.
1200 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
1202 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
1203 commented-out version of gh_eval_str()
1205 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
1207 * socket.c (scm_bind): free soka after use.
1209 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
1211 * stime.c (tzvar): new variable.
1212 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
1213 avoid memory leaks when allocating.
1215 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
1217 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
1220 * gc.c, tags.h: Doc fixes.
1222 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1224 * eval.c (macro-eval!): Removed. This function was a design bug.
1225 It allowed memoized code to leak out to the scheme level. Most
1226 things that you could do with `macro-eval!' can be done with
1229 1997-12-20 Tim Pierce <twp@skepsis.com>
1231 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
1232 scm_fgets now depends on ftell(3) to know how many bytes were
1235 1997-12-15 Tim Pierce <twp@skepsis.com>
1237 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
1238 dealing with strings.
1240 1997-12-13 Tim Pierce <twp@skepsis.com>
1242 Make %read-line more suitable for implementing read-line efficiently.
1243 * ioext.c (scm_read_line): Strip the terminating newline from a
1244 string, and return a cons of the string and its terminator.
1246 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
1247 of the string that is read is stored in this memory location.
1248 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
1249 * genio.c, genio.h (scm_do_read_line): Update caller.
1250 * ports.h (scm_ptobfuns): Update typedef.
1251 * fports.c (scm_fptob, scm_pipob): Update struct.
1253 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1255 * filesys.c (set_element): Return file descriptor.
1256 (fill_select_type): Return the highest file descriptor.
1257 (scm_select): Tell select about the highest file descriptor. On
1258 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
1259 Therefore the extra overhead for calculating the maximum fd seems
1260 to be more than compensated. Is this correct? In any case,
1261 scm_internal_select will be much faster with this info.
1262 (scm_select, fill_select_type, set_element): Don't accept any kind
1263 of object in the file descriptor list or vector.
1265 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1267 * iselect.c (finalize_fd_sets): Bugfix.
1269 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1271 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1272 when using scm_internal_select (since we might switch to another
1275 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1277 * simpos.c (scm_system): always define: use sysmissing if not
1278 available. Check for HAVE_SYSTEM instead of _Windows (does
1279 Windows lack system or does it have an unusable one?).
1280 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1281 Let the argument be optional: if not supplied, call system(NULL).
1283 * ports.c (scm_close_port): relax the type check from OPPORTP to
1284 PORTP; closing a closed port is allowed.
1286 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1288 * fports.c (scm_fgets): Return if the last char in a chunk is
1289 newline. When fgets returns a string whose length is `size-1', it
1290 is ambiguous whether a whole line was retrieved, so we must check
1291 explicitly whether a line terminator is present.
1293 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1295 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
1296 before taking the CDR. (Thanks to Harald Meland.)
1298 * filesys.c (scm_stat): Slightly optimized.
1300 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
1302 * ports.c (scm_close_port): Make sure the port is open before
1305 * guile-snarf.in: Pass args through to gcc in a way that preserves
1306 whitespace boundaries. (Thanks to Greg Badros.)
1308 1997-12-02 Tim Pierce <twp@skepsis.com>
1310 * stacks.c (scm_frame_procedure): Reverse the logic in the return
1311 statement. (Thanks to Doug Evans for pointing this out.)
1313 1997-12-01 Tim Pierce <twp@skepsis.com>
1315 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
1317 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
1319 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
1320 errno macro expansion of this field name. (errno is a C
1321 preprocessor macro on some systems.)
1323 1997-11-29 Tim Pierce <twp@skepsis.com>
1325 * iselect.c: Doc fix.
1327 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
1329 * init.c (scm_start_stack): Removed initialization of
1330 scm_the_last_stack_var.
1332 * backtrace.h: Declare scm_the_last_stack_var.
1334 * backtrace.c: Define scm_the_last_stack_var.
1336 * root.c (mark_root): Don't mark the_last_stack_var.
1338 * root.h (scm_root_state): Removed the_last_stack_var.
1340 * throw.c: Added #include "fluids.h"
1341 (ss_handler): `the-last-stack' is now a fluid.
1343 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
1344 --> the_last_stack_fluid.
1346 * backtrace.c: Added #include "fluids.h"
1347 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
1348 (scm_backtrace): `the-last-stack' is now a fluid.
1350 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
1351 after scm_init_fluids.
1353 1997-11-28 Tim Pierce <twp@skepsis.com>
1355 * iselect.c: #ifdef USE_THREADS around thread-related includes.
1357 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
1358 DLSYM_ADDS_USCORE to decide whether to add an underscore.
1360 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1362 * iselect.c (coop_next_runnable_thread,
1363 coop_wait_for_runnable_thread): Disable interrupts so that no
1364 async is executed before a potential error_revive.
1365 (scm_internal_select): Disable interrupts during the parts of the
1366 code which manipulate the sleep queue and the file descriptors.
1368 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1370 * Makefile.am: Added iselect.c and iselect.h.
1372 * coop.c (coop_qinit): Initialize fields used by
1373 scm_internal_select.
1374 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1375 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1376 replacement in iselect.c.
1377 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1378 coop_join): If GUILE_ISELECT enabled, use
1379 coop_wait_for_runnable_thread instead of
1380 coop_next_runnable_thread.
1381 (usleep, sleep): New replacements for system functions if
1382 GUILE_ISELECT is enabled.
1384 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1386 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1388 * filesys.c: Added #include "iselect.h". Moved FD-macros to
1389 iselect.h. Implement Scheme level `select' using
1390 scm_internal_select. (See NEWS.)
1392 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1394 * init.c: Call scm_init_iselect.
1396 * iselect.h, iselect.c: New files. Implements
1397 scm_internal_select. (See NEWS.)
1399 1997-11-27 Tim Pierce <twp@skepsis.com>
1401 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1402 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1403 and scm_must_free, since ultimately the string returned will be copied
1404 by scm_makfrom0str anyway. Also, read any characters that may have
1405 been pushed onto the port with scm_ungetc.
1406 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1407 * ioext.c (scm_read_line): Free string after Guilifying it.
1408 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
1410 1997-11-26 Anthony Green <green@hoser.cygnus.com>
1412 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
1414 * gh.h: Safely wrap prototypes for c++ usage.
1416 1997-11-25 Mark Galassi <rosalia@cygnus.com>
1418 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
1419 gh_repl (argc, argv).
1421 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1423 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1424 and to invoke scm_shell().
1425 (gh_launch_pad): took out the loading of boot-9.scm from here,
1426 since it is probably best to let the user control that. In fact,
1427 gh_repl() now invokes scm_shell() which does that.
1429 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1431 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
1434 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
1436 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
1437 yesterday's underscore patch. (Thanks to Marius Vollmer for
1440 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
1442 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
1443 DLSYM_ADDS_USCORE is not defined.
1445 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
1447 * gh_data.c (gh_uniform_vector_length):
1448 (gh_uniform_vector_ref): started implementing the uniform types in
1451 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
1453 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1454 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1456 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1458 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1459 configure.in was changed).
1461 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
1463 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1464 * Makefile.in: Regenerated.
1466 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1468 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1469 OPORT is an `open' port, not an output port.
1471 * filesys.c (scm_close, set_element, get_element, scm_chown,
1472 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
1473 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
1474 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
1475 scm_close_port, scm_port_line, scm_set_port_line_x,
1476 scm_port_column, scm_set_port_column_x, scm_port_filename,
1477 scm_set_port_filename_x, scm_port_mode,
1478 scm_close_all_ports_except, scm_set_current_output_port,
1479 scm_set_current_error_port): Likewise
1480 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1481 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
1483 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
1484 * backtrace.c (display_backtrace_body): Likewise
1485 * fports (scm_setvbuf): Likewise
1486 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
1487 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
1488 scm_getpeername, scm_send, scm_sendto): Likewise
1489 * unif.c (scm_uniform_array_write): Likewise
1491 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
1493 Minor problems with substring-related tag changes.
1494 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1495 exactly what we want to leave in to detect substrings.
1496 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1497 * tags.h: Fix diagrams and comments describing the S tag bit;
1498 remove vestigial remarks about the D tag bit.
1499 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
1500 * strings.c: Formatting tweaks.
1502 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1503 variable first; then SCHEME_LOAD_PATH, with a warning message.
1504 (scm_parse_path): New function.
1505 * script.c: Doc fixes.
1507 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1509 Readline support, from Daniel Risacher.
1510 * readline.c, readline.h: New files.
1511 * init.c: #include "readline.h".
1512 (scm_boot_guile_1): Call scm_init_readline, if we have it.
1513 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1514 * Makefile.in: Regenerated.
1515 * scmconfig.h.in: Regenerated, after change to ../configure.
1517 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1519 * gh.h: gh_vector_set -> gh_vector_set_x
1521 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1523 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1524 with the ! -> _x mapping when going from Scheme to C.
1526 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1528 * gh.h (gh_reverse):
1536 (gh_assoc): added these gh_ functions implemented as macros.
1538 * gh_predicates.c (gh_null_p):
1539 (gh_string_equal_p): added these two missing predicates.
1541 * gh_list.c (gh_append):
1546 (gh_set_cdr_x): added these routines as I go through and try to
1547 complete the picture R4RS functions that should be mirrored in the
1550 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1552 * tags.h (scm_tc7_substring): Changed the comment and code to
1553 conform with the changes below. Folks! We have suddenly two new
1554 free tc7 codes!!! Jummy, jummy!
1556 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
1558 * Makefile.in: Rebuilt.
1559 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
1561 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
1562 * unif.c (scm_vector_set_length_x): Don't handle multibyte

1573 * gc.c (scm_gc_mark): Don't handle mbstrings.
1574 (scm_gc_sweep): Likewise.
1575 * eval.c (SCM_CEVAL): Don't handle mbstrings.

1578 (SCM_TYP7D): Removed.
1579 (scm_tc7_mb_string): Removed.
1580 (scm_tc7_mb_substring): Removed.

1583 Don't include "mbstrings.h".
1584 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
1585 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
1587 Don't include "mbstrings.h".
1588 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
1589 (SCM_SYMBOL_SLOTS): Define as 4.
1590 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
1591 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
1592 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
1593 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
1594 struct.c, threads.c, throw.c, unif.c, variable.c: Use new

1611 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
1612 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
1614 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1616 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1618 * gh_test_c.c (c_vector_test): some improvements on the vector
1621 * gh.h (gh_vector): this used to exist but do the wrong thing.
1622 Now it (almost) does the right thing, though it takes a list
1623 instead of the individual arguments. I need to see how it could
1625 (gh_list_to_vector): added this function as a macro. Corresponds
1626 to Scheme's (list->vector ...).
1627 (gh_vector_to_list): added this function as a macro. Corresponds
1628 to Scheme's (vector->list ...).
1630 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1631 gh_vector_ref, so that it resembles the Scheme routines more.
1632 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1633 resembles the Scheme routines more.
1634 (gh_make_vector): this used to be (stupidly) called gh_vector().
1635 This is the right name, since it does the same thing as the Scheme
1636 (make-vector ...) procedure.
1638 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1640 * ports.h: #include "libguile/print.h"
1642 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
1643 Some indentation fixes.
1645 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
1646 longer a user field; New field: class_flags.
1648 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
1650 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
1652 * gh_data.c (gh_bool2scm): new function which replaces
1653 gh_int2scmb(), which is now tagged as obsolete.
1655 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1657 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1658 macros should by convention not test for NIMPness.)
1659 (SCM_COERCE_OPORT): Adjust indentation.
1661 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1662 SCM_NIMP test before SCM_PRINT_STATE_P.
1664 * struct.c, struct.h, gc.c: Renamed:
1665 scm_struct_i_layout --> scm_vtable_index_layout
1666 scm_struct_i_vcell --> scm_vtable_index_vcell
1667 scm_struct_i_vtable --> scm_vtable_index_vtable
1668 scm_struct_i_printer --> scm_vtable_index_printer
1669 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1671 * struct.c (scm_print_struct): Use new printer slot; Default
1672 printing: Also output hex code of vtable so that type identity
1673 will be indicated as well.
1674 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1675 Removed struct_printer_var; Removed struct-vtable-offset;
1676 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1677 vtable-offset-user): New constants.
1679 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
1680 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
1681 If this slot contains a procedure, use that to print structures of
1682 the type represented by this vtable.
1684 * print.c (scm_iprin1): Don't print arguments of macro
1685 transformers. (They are always: exp env.); Bugfix: Unmemoize
1686 transformer source with correct environment.
1688 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1690 Streamlining of call-with-dynamic-root:
1692 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
1693 there is now only one catch.
1694 (cwdr_outer_body): Removed.
1695 (cwdr_handler): New function.
1696 (scm_internal_cwdr): New function to perform the function of cwdr
1697 but take args that are more useful to C code. Also, the handler
1698 is now invoked *outside* of the new dynamic root, like the docs
1699 say. We no longer have to catch absolutely all errors, the caller
1700 is responsible for using a handler that does not throw, if he
1702 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1703 * root.h (scm_internal_cwdr): New prototype.
1705 Even more but risky streamlining:
1707 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1708 allocation of the jumpbuf of a root continuation. The changes
1709 below are controlled by it. They are now deactivated.
1710 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1711 the JMPBUF of the scm_rootcont to NULL before returning.
1713 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1714 when they are non-NULL.
1715 (scm_gc_mark): Likewise, mark only when non-NULL.
1717 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1718 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1720 * gc.c (scm_done_malloc): New function.
1721 gc.h (scm_done_malloc): New prototype.
1723 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
1724 (struct scm_print_state) [revealed]: New field.
1725 (scm_print_state_vtable): Make visible to the outside world for
1726 type checking purposes.
1727 (scm_valid_oport_value_p): New prototype.
1729 * print.c (scm_valid_oport_value_p): New function to check whether
1730 a certain value is acceptable as a port argument.
1731 (scm_print_state_vtable): New variable.
1732 (scm_free_print_state): Set `revealed' field to false.
1733 (scm_iprin1): Call user supplied closure printer with
1734 scm_printer_apply. Print in the traditional way when there isn't
1735 one or when it returns #f.
1736 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1737 Accept a port/print-state pair in addition to just a port.
1738 (scm_prin1): Don't return the print_state to the pool when it has
1740 (scm_printer_apply): Set `revealed' field of print_state to true.
1741 (scm_init_print): Set scm_print_state_vtable.
1742 (print_state_fluid, print_state_fluid_num): Removed.
1744 * throw.h (scm_handle_by_proc_catching_all): New prototype
1745 throw.c (scm_handle_by_proc_catching_all): New function
1747 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1749 * Makefile.in: Regenerated with automake 1.2c.
1751 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1753 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1754 was looping endlessly.
1756 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1758 * strports.c (scm_eval_string): Don't close the port.
1760 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1761 former returns a nice normal integer. (Thanks to Daniel
1764 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1766 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1767 makefile variable as a build parameter called LIBS. The
1768 build-guile program will use this, for the time being.
1769 * Makefile.in: Regenerated.
1771 Thanks to Shiro Kawai:
1772 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1773 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1776 * Makefile.in: Regenerated with automake 1.2a.
1778 * script.c (scm_compile_shell_switches): If we hit the -c or --
1779 arguments, don't set the car of (command-line) to scm_usage_name,
1780 the prettified name of the guile executable; give it the full
1781 path, the way shells usually handle $0.
1783 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1785 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1786 Scheme-level name `array-map' and renamed `serial-array-map' to
1787 `serial-array-map!'.
1789 * backtrace.c: Introduced exception handlers which now enclose
1790 `display-error' and `display-backtrace' so that error reporting
1791 won't get into infinite loops if an error occurs during displaying
1792 of the error. This can very easily happen with user supplied
1793 print call-back routines.
1795 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1797 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1798 the names `serial-array-map' and `array-map' should be removed.)
1800 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1802 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1803 Added #include "objects.h"
1805 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1806 Add #include "feature.h".
1808 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1809 (modinclude_HEADERS): Added objects.h.
1811 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1812 This test is needed at many places in the code and should be
1813 abstracted. (Motivated by the need of this test in libguiletk.)
1815 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1816 (scm_eval_string), load.c (scm_primitive_load,
1817 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1818 Use SCM_EOF_OBJECT_P.
1820 * eval.c (scm_init_eval): Add feature `delay'.
1822 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1824 * scmhob.h: Removed.
1826 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1828 * list.h (SCM_LISTn): New macros. Make list creation in C code
1829 prettier. The idea comes from STk.
1831 * sequences.h, sequences.c, append.h, append.c: Removed. These
1832 files implemented non-R4RS operations which would encourage
1833 non-portable programming style and less easy-to-read code.
1835 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1838 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1839 sequences.h, #include append.h.
1841 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1844 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1846 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1848 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1850 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1852 * eval.c: Added #include "objects.h"
1854 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1857 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1858 adjacent smob numbers.
1860 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1862 * procprop.h: Added declaration of scm_i_inner_name.
1864 * gsubr.c: New global symbol scm_i_inner_name.
1866 * debug.c (scm_procedure_name): Try procedure property
1867 `inner-name' if `name' fails.
1869 * print.c (scm_iprin1): Use scm_macro_name.
1871 * eval.c (scm_m_define): Give names to macros as well; Only the
1872 first top-level definition gives a procedure/macro a name.
1873 Otherwise confusing names can turn up in backtraces.
1874 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1875 `name'; Give names to macros as well.
1877 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1878 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1881 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1883 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
1885 (prinmacro): Removed. The code has been moved/merged into print.c
1886 in order to decrease code redundancy. We want macros to print in
1887 a way equivalent to procedures, and it would be silly to duplicate
1888 the required code. (We don't want to maintain two places.)
1889 (macrosmob): Print field is now a NULL pointer.
1891 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1892 scm_macro_transformer): New prototypes.
1893 (scm_tc16_macro): Declared.
1895 * print.c (scm_iprin1): Added code for printing of macros. Macros
1896 are now printed in a way equivalent to procedures.
1898 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1900 * procs.h (scm_closure_p): Added declaration.
1902 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1904 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
1905 Shouldn't pass "heap" as the subr name.
1907 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1909 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
1910 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
1911 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1912 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1913 SCM_BOOL_T. Any non-false value is true.
1915 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1917 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1918 scm_gensym): Added prototypes.
1920 * symbols.c (scm_gensym): New function. This will speed up
1921 certain types of applications (such as macro systems) which
1922 generate lots of symbols.
1924 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1926 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
1928 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
1930 * unif.c (scm_shap2ra): tighten the checking of the array dimension
1931 specifier, since (2) or (2 . 3) would cause SEGV.
1932 (scm_transpose_array): more argument checking fixes.
1934 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1936 * Makefile.in: Regenerated.
1938 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1940 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
1942 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1944 * error.c, error.h (scm_error_callback): Removed (see NEWS).
1946 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
1948 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
1949 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
1952 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
1953 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1954 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
1955 scm_array_p, scm_array_rank, scm_array_dimensions,
1956 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
1957 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
1958 scm_array_prototype): Added case scm_tc7_wvect.
1960 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
1962 * errno.h: prototype for scm_strerror.
1963 * error.c (scm_strerror): new procedure.
1965 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1967 * list.c (scm_list_append_x): Allow non-pair as last argument.
1968 This is consistent with the R4RS append and is probably the
1969 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1971 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1973 * stime.h: prototype for scm_times.
1974 * stime.c (scm_times): new procedure.
1975 * ioext.c (scm_fseek): if the first argument is a file descriptor
1977 (scm_ftell): if the first argument is a file descriptor call lseek
1979 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
1980 * filesys.c (scm_chmod): if the first argument is a file descriptor,
1982 (scm_chown): if the first argument is a port or file descriptor,
1984 (scm_truncate_file): new procedure.
1985 Add DEFER/ALLOW INTS to a few other procedures.
1986 (scm_fsync): new procedure.
1987 (scm_open_fdes): new procedure.
1988 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
1990 (scm_fcntl): the first argument can now be a file descriptor. The
1991 third argument is now optional.
1993 * posix.c (scm_execl, scm_execlp): make the filename argument
1994 compulsory, since omitting it causes SEGV.
1995 (scm_sync): return unspecified instead of #f.
1996 (scm_execle): new procedure.
1997 (environ_list_to_c): new procedure.
1998 (scm_environ): use environ_list_to_c. disable interrupts.

2005 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
2006 argument to SCM_ASSERT. Furthermore, the name of the function
2007 should be passed as first argument when signalling
2008 SCM_WNA. (Thanks to Thomas Morgan)
2010 * gsubr.c (scm_gsubr_apply): From Radey Shouman
2011 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
2012 dispatches on the number of actual args has a default case
2013 reporting an internal error. This is a vestige from a version
2014 that mallocated a SCM vector to hold the arguments. In the
2015 current version this check is too late: if it ever happens we will
2016 have already overstepped the bounds of the array.
2018 Also, the patch [...] adds a check for too many actual arguments."
2020 mdj: Removed check for "internal programming error".
2022 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2024 * gh_io.c (gh_write): New function.

2039 fold in the functionality of scm_primitive_dup.
2040 (scm_primitive_dup): deleted.

2087 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied

2169 memory leak when the linking code throws an error. Now the code
2170 leaks a whole dynamically linked library when must_malloc throws,
2171 but that should be much less likely.
2173 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
2175 Changes to compile under gnu-win32, from Marcus Daniels:

2213 think this is left over from the (eq? '() #f) days.
2215 * read.c (recsexpr): Give this a dummy definition if
2216 DEBUG_EXTENSIONS isn't #defined.
2218 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>

2235 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2237 * simpos.h: prototype for scm_primitive_exit.

2245 have to do this explicitly. Also, if regexp/basic is supplied, then
2246 turn off REG_EXTENDED.
2247 (scm_init_regex_posix): New regexp/basic symbol.
2248 (REG_BASIC): #define this if it is not already present.

2291 * root.c: Establish a reliable catch-all handler for the new root.
2292 After all the Scheme handler function might signal an error too,

2295 (cwdr_outer_body): New function, to establish the user's handler,
2296 and pass control to cwdr_inner_body.

2308 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2309 the feeling that real thread systems will not need this...
2311 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2313 Try to detect when people are using one version of libguile and a

2325 primitive definitions under their Scheme names.
2327 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2328 1:2. Helps avoid confusion between installed and uninstalled libs.
2330 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2333 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2334 backslash from definition; this should be used like: GDB_INTERFACE;
2336 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2338 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
2339 new port unbuffered until its stream has been set.
2341 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2343 * ports.h: new prototype.

2353 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2355 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA

2359 * tag.c (scm_tag): Remove unreachable statement.
2360 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2361 top of the word, it should be unsigned.
2363 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2364 is defined, to avoid warnings; it's only used in the
2365 conflict-checking code. Which might go away anyway.
2366 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2367 conditionals; put the label definition in an #if too, to stifle
2370 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2371 ChangeLog-threads in the distribution.
2372 * Makefile.in: Regenerated.

2382 * load.c (scm_init_load_path): Append $(datadir)/guile to
2383 %load-path, so modules do not have to be installed in Guile's
2384 current version directory.
2386 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2388 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2389 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2390 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2391 call the sysdep functions with deferred ints.

2413 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2414 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2417 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2419 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2420 supplied. (Change from Tim Pierce.)
2422 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2424 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2425 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2426 default and not `()'. `#f' is the canonical non-value in Scheme,
2429 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2431 * struct.c (struct_printer): New variable that holds a handle on
2432 the Scheme variable *struct-printer*. This variable can be set by
2433 Scheme code to override the printing of structures.
2434 (scm_print_struct): If struct_printer is set, call it. If it is
2435 not set, or returns #f, print the structure in the old fashion.
2436 Include "eval.h" for scm_apply.
2438 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2440 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2441 scm_struct_i_n_words to get the number of fields, not
2442 -scm_struct_n_extra_words.
2444 On the route to fancier struct printing:
2445 * struct.c (scm_print_struct): New function to print a structure.
2446 Include "genio.h" to support it. This function doesn't do
2447 anything interesting right now, but I think it should be here
2449 * struct.h: Include "print.h" and add prototype for
2451 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2452 print structures ourself.
2454 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2456 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2457 before applying the handler in case it doesn't return.
2459 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2461 * scmsigs.h, async.h: updated.
2463 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2466 * posix.c (scm_uname): interpret only negative values as an error.
2467 Solaris normally returns a positive value.
2469 * script.c (scm_compile_shell_switches): if we are not going into
2470 an interactive repl, set scm_mask_ints to zero so that asyncs can
2473 * simpos.c (scm_system): don't ignore/unignore signals around
2476 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2479 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2480 done in boot-9.scm instead.
2482 * scmsigs.c, async.c: Major rewriting of signal handling code.
2483 (scm_sigaction): new procedure.
2484 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2486 (scm_raise): return unspecified, throw error on failure.
2488 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2490 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2491 feature, to help boot-9.scm decide whether to import the regex
2494 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2496 * eval.c: Include scmconfig.h at the beginning of the file so that
2497 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2500 * regex-posix.c: #include "_scm.h" before conditionally #including
2501 <regex.h>; the former defines HAVE_REGCOMP.
2503 * regex-posix.c: #include <regex.h> conditionally, so the file is
2504 CPP'able (for dependency scanning) even on systems that don't have
2507 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2509 Add new R4RS-compliant syntax for keywords.
2510 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2511 regardless of the setting of the `keywords' read option.
2512 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2513 can be re-read no matter what the setting of the `keywords' read
2516 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2518 Add support for POSIX regular expressions.
2520 * regex-posix.c, regex-posix.h: New files. (Some code
2521 is taken liberally from rx/rgx.c in the old Guile dist.)
2523 * init.c: Include regex-posix.h.
2524 (scm_boot_guile_1): Call scm_init_regex_posix.
2526 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2527 Add regex-posix.[ch] sources.
2528 * Makefile.in: Regenerated.
2530 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2531 to do this automatically? It didn't for me, bleh.)
2533 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2535 * fports.c (print_pipe_port): New function.
2536 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2537 latter doesn't even take the right arguments.
2539 * Makefile.am: Increment shared lib revision number. I think
2540 sometimes the uninstalled Guile finds the installed shared lib;
2541 Gord says doing this might help. As things turned out, I can't
2542 say whether it does.
2543 * Makefile.in: Regenerated.
2545 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2546 passing it as the closure argument to scm_boot_guile. (Bill
2549 * ports.c (print_void_port, putc_void_port, puts_void_port,
2550 write_void_port, flush_void_port, getc_void_port, close_void_port,
2551 noop0): Use ANSI prototypes instead of K&R declarations, so the
2552 initialization of void_port_ptob gets aggressively type-checked.
2553 Fix arguments of print_void_port and write_void_port. (Bill

2587 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2589 * script.c (scm_find_executable): Use prototype-style definition
2590 here; apparently it's not quite right to have const in a prototype
2591 and then use a K&R declaration. I wonder if stuff like this will
2592 go away if we compile with -Wrequire-prototypes, or whatever that
2593 is... (Bernard URBAN)
2595 * scmhob.h: New text from Bernard URBAN.
2597 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2599 * script.c: Don't #define const on hpux. Configure takes care of
2600 this. (Thanks to Larry Schwimmer.)
2602 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2603 decide whether to #include <unistd.h>, instead of listing a bunch
2604 of systems. Don't #include stdio twice. Removed dyked-out
2605 definition of scm_find_impl_file.
2607 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2609 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2610 library version info to 1:0.
2611 * Makefile.in: Regenerated.
2613 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

2617 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2618 throw.c: Update copyright years; these files have been worked on
2619 significantly in 1997, but only had copyright years for 1996.
2620 Also, change name of copyright holder on some from Mikael
2621 Djurfeldt to Free Software Foundation; he has signed papers
2622 assigning the changes to the FSF.
2624 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2625 reason not to give the user the option.
2627 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2628 Return #f on end-of-file when scanning table (i.e. when called
2629 with no arguments). Try to catch errors, when we can.
2630 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2632 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2633 external declarations. These are useful.
2635 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2637 * posix.c: don't include <sys/select.h> or define macros for
2638 select, since they were not used in this file.
2640 * filesys.c (scm_select): make the fifth parameter microseconds,
2641 not milliseconds. let the fourth parameter be either a real value
2642 or an integer or #f. The first, second and third arguments can
2643 now be vectors: the type of the corresponding return set will be
2645 (set_element, get_element): new static procedures.
2647 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2649 * strports.c (scm_eval_string): New function.
2650 (scm_eval_0str): Trivially re-implemented in terms of
2652 * strports.h (scm_eval_string): New extern decl.
2654 * net_db.c (h_errno): Add extern decl for this.
2656 * fports.c (local_pclose): New function.
2657 (scm_pipob): Use it in the initializer here.
2660 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2661 Use a meaningful error message when signalling an error. For
2662 this, scm_gethost must check h_errno rather than errno.
2664 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2666 * Makefile.in: Regenerated, using automake-1.1p.
2668 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2670 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2671 not SCM_UNSPECIFIED.
2673 * script.c (scm_compile_shell_switches): don't append (quit) if
2675 (scm_shell): call scm_exit_status and exit on the result of the
2678 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2680 Ensure that shared substrings are handled properly when passed to
2681 a system call or other foreign function. Many thanks to Tim
2683 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2684 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2685 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2686 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
2687 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
2688 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
2689 (scm_display_error_message): use RO macros when strings may be RO.
2690 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
2691 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
2692 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

2696 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
2697 scm_strftime), vports.c (scm_make_soft_port): use
2698 SCM_COERCE_SUBSTR to make sure shared substrings are
2701 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2703 * error.c (scm_error): Add newline to error message.
2705 * init.c (scm_init_standard_ports): Doc fix.
2707 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2709 * dynl-shl.c: Completely replaced with new code from Bernard
2712 * script.c (scm_ice_9_already_loaded): New variable.
2713 (scm_compile_shell_switches): Use it.
2715 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2717 * filesys.c (scm_input_waiting_p): add missing third argument to
2720 * stime.c (scm_localtime): copy the result of localtime before
2721 calling gmtime in case they share a buffer.
2722 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2725 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2727 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2729 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2731 * Makefile.am (check-local): New target, which causes 'make check'
2732 to run gh_test_c and gh_test_repl, with some trivial input.
2733 * Makefile.in: Rgnrtd.
2735 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2737 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2740 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2742 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2743 sure how this was supposed to work.
2744 (scm_async_click): don't send SCM_TICK_SIGNAL.
2745 (scm_init_async): don't initialize %tick-thunk.
2747 * the following change doesn't affect the Scheme interface:
2748 gc-thunk is called at the end of garbage collection. however it's
2749 no longer implemented by pretending it's a signal.
2751 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2752 system async corresponding to scm_gc_thunk.
2753 * async.h: declare scm_gc_async.
2754 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2755 gc-thunk directly, instead of going through a signal handler.
2756 (scm_gc_async): new variable, points to the GC system-async.
2757 (scm_init_async): save the GC async as scm_gc_async instead
2758 of using system_signal_asyncs.
2759 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2761 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2763 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2764 Don't screw up if we're interrupted.
2765 * Makefile.in: Regeneradet.
2767 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2769 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2771 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2772 we're not using AM_INIT_GUILE_MODULE any more.
2773 * Makefile.in: Reneregated.
2775 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2777 Functions for finding variable bindings, grace à Tim Pierce.
2778 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2779 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2781 Get 'make dist' to work again.
2782 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2783 * Makefile.in: Regenerated, like a surry without a fringe on top.
2785 Changes for reduced Guile distribution: one configure script,
2787 * configure.in, configure: Removed.
2788 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2789 real configure script lives.
2790 * Makefile.in, scmconfig.h.in: Regenerated.
2792 * init.c: #include "script.h", to get prototype for script.c's
2795 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2797 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2798 scm_must_malloc, not raw malloc.
2800 * script.c (scm_compile_shell_switches): Dyke out debugging output
2803 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2805 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2807 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2808 system has them. Hope this is safe. Previously
2809 sys/timeb.h was included if HAVE_FTIME was defined or if
2810 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2811 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2813 * ioext.c (scm_setfileno): add missing third argument to
2814 scm_misc_error call.
2816 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2818 * eq.c (scm_equal_p): Correctly compare strings of different
2819 varieties. (Thanks to Tim Pierce.)
2821 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2823 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2824 #! block comment must occur on a line all by itself.
2826 Move most of the guts of shell command processing into libguile,
2827 so guile.c can be very small (and eventuallly auto-generated. (I
2828 mean, generated mechanically, not self-generated. Hmm.))
2829 * guile.c, script.c, script.h: New source files.
2830 * init.c (scm_boot_guile_1): Call scm_init_script.
2831 * libguile.h: #include "script.h".
2832 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2833 targets, for new executable.
2834 (libguile_la_SOURCES): Mention script.c.
2835 (modinclude_HEADERS): Add script.h.
2836 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2837 not dynamic linking is enabled. This is because we're generating
2838 executables now. Move CY_AC_WITH_THREADS call after those, so the
2839 values of cy_cv_threads_libs captures the libs chosen above.
2840 * Makefile.in, configure, aclocal.m4: Regenerated.
2842 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2843 We don't maintain this interface any more, and it just confuses
2846 * alloca.c: #include <scmconfig.h>, not <config.h>.
2847 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2848 it'll get included in disties.
2850 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2852 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2853 be distributed, because they confuse people.
2854 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2856 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2858 * configure.in: check for presence of gethostent (not present on
2859 OpenBSD by default).
2860 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2861 * configure, scmconfig.h.in: Regenerated.
2863 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2865 * backtrace.c (scm_backtrace): Split message string across
2866 newlines properly. GCC is more tolerant of this than other
2869 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
2871 Merge threads directory into libguile.
2872 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
2873 threads.h: New source files.
2874 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
2875 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2877 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2878 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2879 coop-threads.c.cygnus, coop-threads.h.cygnus.
2880 * configure.in: If we're using threads, include threads.o in
2882 * _scm.h, libguile.h: threads.h lives in this directory now.
2883 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2884 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2885 currently used, but brought along for information's sake.
2886 * ChangeLog-threads: log from old 'threads' directory.
2887 * Makefile.in, configure: Rebuilt.
2889 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2891 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2894 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2896 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2898 Merge GH interface library into libguile.
2899 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
2900 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2901 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2902 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2904 (EXTRA_libguile_la_SOURCES): ... here.
2905 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2906 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2907 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2908 New variables, describing how to build the gh test programs.
2909 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2910 build the test programs, and we probably should have been linking
2911 libguile.la against them all along, to support AIX shared libs.
2912 Add cflags for threads to CFLAGS; add libs for threads to new
2913 variable THREAD_LIBS, used in Makefile.am.
2914 * ChangeLog-gh: log from old `gh' subdirectory.
2915 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2917 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2919 * acconfig.h: Undo change of Apr 9; including the definition of
2920 PACKAGE in the guile headers conflicts with applications' own
2922 * scmconfig.h.in: Regenerated.
2924 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

2927 (scm_init_filesys): New symbols for use with fcntl.
2928 * filesys.h: Added prototype.
2930 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
2931 when PROC is receiving no arguments.
2933 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2935 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2936 have S_IFSOCK. This is the case under Ultrix.
2938 * posix.c (scm_status_exit_val, scm_status_exit_val,
2939 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2940 Ultrix versions of WIFSTOPPED, etc., which assume that their
2941 arguments are lvalues (hmm).
2943 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2945 * eval.c: Doc fixes.
2947 * throw.c: Doc fixes; rearranged.
2949 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
2951 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
2953 * acconfig.h: Added entry for PACKAGE.
2954 * scmconfig.h.in: Regenerated.
2956 Changes to work with automake-1.1n, which has better libtool support.
2957 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2958 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
2960 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
2962 * Makefile.in: Rebuild.
2964 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2966 * stime.c (scm_mktime): take an optional zone argument.
2967 (scm_localtime): check putenv return value.
2968 (scm_strftime, scm_strptime): moved from posix.c. move #include
2970 stime.h, posix.h: update prototypes.
2971 (bdtime2c, setzone, restorezone): new static procedures.
2972 (scm_mktime, scm_strftime): use them.
2973 (scm_strftime): don't call mktime before strftime. Use
2974 filltime for return value.
2975 (filltime): convert NULL zname to #f.
2976 (scm_strptime): return a count of characters consumed, not
2977 the remaining string.
2979 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2981 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.

2984 Uncomment localtime and mktime.
2986 * configure.in: add AC_STRUCT_TIMEZONE.
2988 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2990 * stime.c (scm_init_stime): don't define ticks/sec.
2991 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2992 return value problem and is still portable.)
2994 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2996 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2997 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2998 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2999 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
3000 cpp_err_symbols.c): Corresponding changes.
3001 * Makefile.in: Regenerated.
3003 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3005 * posix.c (scm_putenv): don't check HAVE_PUTENV.
3006 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
3007 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
3008 * putenv.c: new file, from sh-utils 1.12.
3010 * posix.c (scm_environ): use malloc in place of scm_must_malloc
3011 since allocation isn't for Scheme objects.
3012 (scm_putenv): copy strings before placing in the environment.
3014 * stime.c (scm_current_time): throw an error if time returns -1,
3015 instead of returning #f.
3016 (scm_get_internal_real_time, scm_get_internal_real_time): use
3017 scm_long2num for return value instead of SCM_MAKINUM.
3019 * stime.h: prototypes updated.
3021 * stime.c (scm_time_in_msec): apparently unused, deleted.
3023 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
3025 * configure.in: check for gettimeofday.
3027 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
3028 which may be more usefully portable than a gettimeofday interface.
3030 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
3032 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
3034 * Makefile.in: Regenerated.
3036 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3038 * stime.c (filltime): recovered static procedure.
3039 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
3042 * posix.h: add prototype for scm_close_pipe, remove prototypes for
3043 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
3045 * posix.c (scm_mknod): split the mode argument into type and perms
3046 arguments, like the extra fields returned by stat.
3048 * fports.c (scm_pipob): set the close, free and print procedures.
3049 (scm_close_pipe): new procedure.
3051 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
3052 define them in boot-9.scm
3054 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3056 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
3057 wan't defined. Don't include fd.h.
3059 * Previously fd.h was regenerated whenever configure was run,
3060 forcing a couple of files to be recompiled.
3062 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
3063 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
3064 Check for _fileno as well as _file.
3066 * ioext.c: don't fd.h.
3067 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
3070 * Change the stratigy for getting information about errno
3071 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
3072 generating lists of symbols during the build process, which will
3073 not always work, include comprehensive lists in the distribution.
3074 To help keep the lists up to date, the "check_signals" and
3075 "check_errnos" make targets can be used.
3077 * configure.in: don't check for a command to extract errno codes.
3078 * Makefile.am: update file lists, remove errnos.list and errnos.c
3079 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
3080 check_errnos targets.
3081 (CLEANFILES): remove errnos.c and errnos.list, add
3082 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
3083 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
3084 * errnos.default: deleted.
3085 * cpp_signal.c: new file.
3086 * cpp_errno.c: renamed from errnos_get.c.
3087 * cpp_err_symbols, cpp_sig_symbols: new files.
3088 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
3089 * error.c (scm_init_error): #include cpp_err_symbols instead of
3091 * posix.c (scm_init_posix): don't intern signal symbols. #include
3094 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
3096 * strop.c (scm_i_index): allow the lower bound to be equal to the
3097 length of the string, so a null string doesn't always give an error.
3099 * posix.h: new prototypes.
3100 * posix.c (scm_status_exit_val, scm_status_term_sig,
3101 scm_status_stop_sig): new functions, as in scsh. They break down
3102 process status values as returned by waitpid.
3104 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
3106 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
3107 configure doesn't know about it.
3109 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3111 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
3113 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
3114 which defines C variables with global linkage.
3116 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3118 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
3121 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
3123 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
3124 has time to check why this doesn't work well with continuations.
3126 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
3128 * Fix shell syntax error; some shells won't tolerate
3129 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
3131 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3133 * posix.c (scm_uname): throw an error if uname fails instead
3136 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
3138 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
3141 * async.c (scm_ints_disabled): definition moved from error.c.
3143 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3145 * acconfig.h: Removed PACKAGE.
3147 * scmconfig.h.in: Regenerated.
3149 * snarf.h: g++ says it's non-portable not to specify the first
3150 argument in a varargs declaration. I introduced the first
3151 argument by using preprocessor conditionals.
3153 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
3155 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
3156 (scm_freopen): use RO string macros for filename and modes.
3157 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
3159 * posix.c (scm_getgrgid): simplify conversion of name to C string.
3160 (scm_mknod): use RO string macros for path.
3162 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
3163 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
3165 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
3166 use SCM_ROSTRINGP and SCM_ROCHARS.
3168 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3170 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
3173 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
3174 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
3175 support for byte vectors.
3177 * print.c (scm_iprin1): Limit number of vector elements printed
3178 according to pstate->length.
3180 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3182 * backtrace.c (scm_display_error_message): don't segv if message
3185 * error.h: prototype for scm_error_scm.
3187 * error.c (scm_error_scm): new procedure, reimplements scm-error
3188 in C and uses scm_error.
3190 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3192 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
3193 pointer to the Scheme variable read-hash-procedures and intern it
3194 in scm_init_read. Modify scm_read_hash_extend and
3195 scm_get_hash_procedure to use the pointer.
3197 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3199 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
3200 (SCM_KEYWORD_STYLE): defined.
3202 * read.c (scm_read_opts): add a keywords option. This isn't a
3203 boolean option, in case someone wants to add support for DSSSL
3205 Setup scm_keyword_prefix symbol.
3206 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
3208 I've left keyword support disabled by default, since it doesn't
3209 seem to break the module system and it gives R4RS standard behaviour.
3210 It can be reactivated with (read-set! keywords 'prefix).
3212 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3214 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
3215 before constructing arbiter.
3217 * eval.c (scm_m_define): Bugfix: Check that the object is a
3218 closure before setting the procedure property!
3220 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
3222 * ports.c: Removed `ungetc-char-ready?'.
3224 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
3226 * read.c (scm_init_read): intitialise scm_read_hash_procedures
3227 (idea from Mikael: make it a pair so scm_permanent object only
3229 (scm_read_hash_extend): don't call scm_permanent_object.
3230 (ideas from Mikael): if chr is already in the list, replace its
3231 procedure instead of appending it again. If proc is #f, remove
3233 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
3235 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
3237 * gdbint.c (gdb_read): update scm_lreadr usage.
3239 * load.h: update prototypes.
3241 * load.c (scm_primitive_load, scm_read_and_eval_x,
3242 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
3244 * read.h: add prototype for scm_read_hash_extend. Change args for
3247 * read.c (scm_read_hash_procedures): new variable.
3248 (scm_read_hash_extend): new procedure.
3249 (scm_get_hash_procedure): new procedure.
3250 (scm_lreadr): use scm_get_hash_procedure instead of an argument
3251 for extended # processing.
3252 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
3253 scm_read_token): remove case_i, sharp arguments. Change callers.
3255 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
3257 * read.h (SCM_N_READ_OPTIONS): increase to 3.
3258 (SCM_CASE_INSENSITIVE_P): define.
3260 * read.c: add case-insensitive option to scm_read_opts.
3261 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
3262 to determine whether to convert symbol case.
3263 (default_case_i): definition removed.
3264 * read.c (scm_read_token): if case_i, downcase ic before doing
3267 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3269 * configure.in: Added configuration option `guile-debug'.
3270 Configure with --enable-guile-debug if you want a bunch of extra
3271 functions used for debugging when developing Guile.
3273 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3275 * procs.c (make-cclo): New undocumented debugging procedure: Make
3276 compiled closure with internal procedure PROC and length LENGTH.
3277 Only compiled if GUILE_DEBUG is defined.
3279 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3281 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3283 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3285 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3286 with 3 or more args internally to the evaluator.
3288 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3290 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3291 with 3 or more args internally to the evaluator. This is mainly
3292 because we don't want to pass entry and exit points of the
3293 debug support twice, but it also seems to increase the speed of
3294 the evaluator for such calls (e. g. (+ 1 2 3)).
3296 * backtrace.c (scm_display_application): New procedure:
3297 display-application; Set fancy printing parameters individually
3298 for different types of display (backtrace, error, application).
3299 (These should of course be customizable!)
3301 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3302 clear the CHECK-flags.
3304 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3306 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3308 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3310 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3311 from pairs with a GLOC in the car.
3313 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3314 otherwise `symbol-hash' will behave badly.
3315 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3316 we get segmentation fault!
3318 * symbols.c: Added #include "weaks.h". New functions:
3319 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3320 moved to an extraneous library when we split libguile.)
3322 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3324 * filesys.c (scm_stat): stat now takes fport arguments too as
3325 documented in the manual.
3327 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3329 * debug.c (scm_single_step): Bugfix: Call continuation with
3330 scm_call_continuation instead of throwing to it.
3332 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3334 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3335 argument wasn't declared to be optional.
3337 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3339 * stime.c (scm_init_stime): Add feature "current-time".
3341 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3343 * throw.h: prototype for scm_exit_status.
3344 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3345 args to derive an exit status. Allows (quit) to work from a
3347 (scm_exit_status): new function.
3350 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3352 * eval.c (scm_deval): Removed some old code.
3353 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3355 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3358 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3361 * procs.c: Introduce the existent C function scm_thunk_p at the
3362 Scheme level as well.
3364 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3366 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3367 used from C to easily lookup the value of a symbol in the current
3370 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3372 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3373 scm_init_unif in this file. This will also fix a previous problem
3376 * configure.in: Added AM_MAINTAINER_MODE
3378 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3380 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3383 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3385 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3386 source files that are not always included in libguile but should
3387 have their dependencies calculated by automake. This variable is
3388 recognized by automake, no further magic is needed.
3389 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3390 to deal exclusively with *.lo files, as it seems. The *.o files
3391 are built automatically when the corresponding *.lo file gets
3394 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3396 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3399 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3401 * unif.c (scm_array_set_x): minor change to argument error checking.
3403 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3405 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3406 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3407 They should only be included in the library at configure.in's
3409 (libguile_la_LDADD): Include the appropriate .lo files here.
3410 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3411 so we know when to build them (and their .lo bretheren).
3412 * configure.in (LIBLOBJS): New substituted variable. We let
3413 configure decide which .o files to include in LIBOBJS, and then
3414 put the corresponding list of .lo files in LIBLOBJS. The latter
3415 is what we pass to libtool.
3416 * Makefile.in, configure: regenerated.
3418 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3420 * symbols.c (scm_sysintern0): New function. Contains the core of
3421 old scm_sysintern but doesn't take a second value argument.
3422 (scm_sysintern): Now uses scm_sysintern0.
3423 (scm_sysintern_no_module_lookup): Renamed to
3424 scm_sysintern0_no_module_lookup and doesn't take a second value
3425 argument any longer.
3427 * symbols.h (scm_sysintern0: Added declaration.
3429 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3430 scm_sysintern when interning option keys. Otherwise we risk
3431 destroying the values of already interned variables.
3433 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3434 scheme-level boolean (use SCM_NFALSEP).
3436 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3438 (scm_backtrace): New function. (C version of old function from
3439 boot-9.scm) Motivation: Make it possible to display backtraces
3440 without depending on boot-9.scm. (I'm uncertain if this
3441 motivation is good enough...)
3443 * root.h (scm_root_state): Add member the_last_stack_var.
3444 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3446 * root.c (mark_root): Mark scm_the_last_stack_var.
3448 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3451 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3453 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3454 1. mark_lazy_catch didn't mark the smob.
3455 2. Both functions above have standard variants:
3456 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3457 free_lazy_catch --> scm_free0.
3459 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3461 * throw.c (scm_internal_lazy_catch): New function.
3462 (scm_lazy_catch): Rewritten to use it.
3463 (scm_ithrow): Handle the new lazy catch representation.
3464 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3465 that doesn't have a jmpbuf is a lazy catch clause.
3466 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3467 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3468 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3470 (scm_init_throw): Register the new lazy-catch smob type.
3471 * throw.h (scm_internal_lazy_catch): decl for new function.
3473 * throw.c (scm_internal_catch): Doc fixes.
3475 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3476 configure.in. Including this might cause problems if applications
3477 that link against libguile include their own copies of alloca, but
3478 if they're using autoconf, they should be adding libguile to LIBS
3479 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3480 the copy in libguile, and things will be okay. (I think.)
3482 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3484 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3486 strop.h: move prototypes too.
3488 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3490 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3493 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3494 etc. I deleted them from filesys.c long ago, but didn't
3495 notice they were here too (although ineffective since
3496 sys/stat.h wasn't included).
3498 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3500 * eval.c: Don't define alloca in GCC case. gcc will automatically
3501 use __builtin_alloca if appropriate.
3503 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3505 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3506 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3507 that values of automatic variables are preserved. See comments
3508 for safe_setjmp for details.
3510 Change from Thomas Morgan:
3511 * variable.c: Include eq.h.
3512 (var_equal): New function.
3513 (variable_smob): Use var_equal as the discriminator for variables.
3515 * throw.c (s_throw): Remove extraneous declaration.
3517 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3518 * eval.c: Add necessary CPP cruft to support that.
3519 * configure, Makefile.in, scmconfig.h.in: regenerated.
3521 Change from Thomas Morgan:
3522 * procprop.c (scm_procedure_properties): Convert the Scheme
3523 boolean returned by scm_procedure_p into a C boolean before using
3524 it as a condition for SCM_ASSERT.
3525 (scm_procedure_property): Likewise.
3527 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3528 indications of Unixness.
3531 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3533 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3535 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3537 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3538 "unknown # object" error messages.
3540 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3541 (scm_i_index) and declare it static. Add a 'direction' argument
3542 to indicate what way the search should go.
3543 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3545 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3546 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3548 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3550 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3552 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3553 to avoid clash with various scsh forks.
3555 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3557 The following two changes (ramap.c, throw.c) are motivated by the
3558 apparent unportability of forward declarations of static arrays of
3559 the form `static foo bar[];'.
3561 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3562 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3564 * throw.c (scm_throw): Moved above scm_ithrow.
3566 * options.h: Removed the extern declarations of scm_yes_sym and
3567 scm_no_sym since these are static.
3569 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3571 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3573 * Makefile.am: remove AWK=@AWK@.
3574 Add a rule for generating errnos.list.
3575 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3577 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3578 don't extract errnos, just set a variable (avoids the
3579 need to recompile error.c just because configure is run.)
3581 * unif.h: update prototypes.
3582 * unif.c (scm_uniform_array_read,write): change the offset and
3583 length arguments to start and end, for consistency.
3585 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3587 * ioext.h: update prototypes.
3588 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3589 scm_read_line_x, it's a more general procedure using an
3590 interface from scsh. read-line and read-line! are now defined
3592 Note that the new read-line trims the terminator
3593 by default, previously it was appended to the returned string. An
3594 optional argument specifies how to process the terminator (scsh
3595 compatible). For the old behaviour: (read-line port 'concat).
3596 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3597 returns a pair, but is converted to multiple values if the scsh
3600 socket.h: update prototypes.
3601 * socket.c (scm_recvfrom): for consistency with other procedures,
3602 take start and end as separate optional arguments.
3603 (scm_recv, scm_recvfrom): don't allow the second argument
3604 to be a size, only a buffer. Change the scheme names to
3605 recv! and recvfrom!. Don't return the buffer.
3607 * ioext.h, posix.h: move prototypes too.
3608 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3609 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3610 "read.h" and "unif.h".
3611 * ioext.c: include "chars.h"
3613 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3615 * dynl.c: The dynamic linking and module registration functions
3616 are now defined even when dynamic linking is not available for the
3617 host system. Some of their functionality can be done without
3618 dynamic linking; when it's really needed, they throw errors.
3620 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3622 * configure.in: Only define DYNAMIC_LINKING when one of the system
3623 dependent functions is detected.
3624 * dynl.c (scm_dynamic_func): New function to get the address of a
3625 function in a dynamic object.
3626 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3627 produced by scm_dynamic_func as the thing to call.
3629 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3631 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3632 (scm_register_module_xxx, scm_registered_modules,
3633 scm_clear_registered_modules): New functions.
3635 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3637 * symbols.c (scm_sysintern): Renamed to
3638 scm_sysintern_no_module_lookup.
3639 (scm_sysintern): New function to take the place of the old
3640 scm_sysintern. It uses the current toplevel lookup closure to give
3641 the symbol its value. This is a temporary hack to put packages
3642 like gtcltk into their own module.
3643 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3644 us whether `scm_top_level_lookup_closure_var' has been initialized
3646 * eval.c (scm_init_eval): Set it.
3648 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3650 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3651 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3653 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3655 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3656 scm_sys_dup): deleted: FD capability will be added to other
3658 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3659 scm_fd_free, fd_smob, scm_intern_fd.
3660 (scm_open): renamed from scm_sys_open. Return a port instead of
3661 an FD object. Make the mode argument optional.
3662 (scm_sys_create): deleted, it's just a special case of open.
3663 (scm_init_filesys): move interning of constants O_CREAT etc.,
3664 here (were previously using SCM_CONST_LONG macro).
3665 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3667 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3668 include "fports.h" and <stdio.h>
3669 (scm_stat, scm_select): don't support FD objects.
3671 * error.h: adjust scm_syserror_msg prototype.
3672 * error.c (scm_syserror_msg): take an extra argument for errno.
3673 Using the global value didn't always work, since it could be
3674 reset by procedure calls in the message or args arguments.
3676 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3677 I don't understand why the check was there (and what about the
3680 * strop.c (scm_string_copy): allow shared substrings to be copied.
3682 * unif.h: corresponding change to prototypes.
3683 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3684 recognize two new optional arguments: offset and length. Allow
3685 the port argument to be an integer (file descriptor, for scsh).
3686 Include <unistd.h> for "read" prototype.
3688 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3690 * socket.c: don't include filesys.h.
3692 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3694 * Makefile.am: add AWK=@AWK@ (?)
3696 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3698 Add a rule to generate errnos.c from errnos.
3699 * error.c (scm_init_error): include errnos.c.
3700 * errnos_cnvt.awk: new file, converts the list of errno codes to
3702 * errnos_get.c: new file.
3703 * errnos.default: new file, contains errnos to try if they can't
3704 be extracted from errno.h.
3705 * configure.in: if using GCC, try and extract errno codes from
3709 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3711 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3712 * Makefile.am: Made libguile into a libtool library.
3713 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3714 Set libtool_libs to indicate that libguile is a libtool library.
3715 See guile/ChangeLog for details.
3716 * .cvsignore: ignore "*.lo", the libtool library objects.
3718 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3720 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3721 use htons in getservbyport argument.
3723 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3725 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3726 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3729 * objprop.c (scm_object_property): No need to take the CDR of the
3730 value returned by scm_object_properties, since Aug 20 change.
3732 * configure.in: When checking for struct linger, #include
3733 <sys/types.h> as well as <sys/socket.h>. I've never known
3734 <sys/types.h> to cause any portability problems, and Solaris's
3735 <sys/socket.h> needs it.
3736 * configure: Rebuilt.
3738 I think the Sun compiler has chosen a perverse way to interpret
3739 ANSI declarations combined with K&R definitions. We'll
3740 appease it a little bit. But when it invades France, we fight.
3741 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3742 * print.h (scm_iprlist): Here too.
3743 * numbers.c (scm_divbigdig): Change definition to match
3744 declaration in numbers.h.
3745 * unif.c (scm_makflo): Change definition to match declaration in
3748 * init.c (scm_boot_guile): Don't return the value of
3749 scm_boot_guile_1. This function doesn't return a value;
3750 scm_boot_guile_1 doesn't return a value (or return at all).
3752 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3755 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3756 compile. I have a feeling this function is a bad idea anyway ---
3757 one should always test for features, not systems.
3759 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3760 semicolons. Only pure luck kept this from being noticed earlier.
3762 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3764 * socket.c (scm_recvfrom): Added missing semicolon.
3766 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3768 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3769 the buffer and start and end positions for scsh networking
3772 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3774 * configure.in: Revert previous change to this file; the problem
3775 is due to transient automake weirdness.
3776 * configure: Rebuilt.
3778 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3779 PLUGIN/guile.libs. configure generates the latter from the former.
3780 * Makefile.in: Rebuilt.
3782 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3783 need this if we install scripts, like guile-snarf.
3784 * configure: Rebuilt.
3786 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3788 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3790 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3792 * socket.c (scm_addr_vector): fix faulty scm_listify.
3794 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3796 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3797 style block comment is no longer considered an error.
3799 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3801 * PLUGIN/guile.libs.in: New file.
3802 * PLUGIN/guile.libs: Removed from repository.
3803 * configure.in: Create PLUGIN/guile.libs from
3804 PLUGIN/guile.libs.in. This is for including additonal libraries
3805 needed for dynamic linking.
3806 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3807 instead of PLUGIN/guile.libs.
3809 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3811 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3813 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3814 occurrences of the given element from the list, not just the
3815 first. This is how the Emacs Lisp functions behave, how the
3816 analogous Common Lisp functions behave, and (I believe) how the
3817 older Maclisp functions worked. I realize that this change may
3818 break code, but it seemed better to break it before the Guile
3821 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3822 Their prototypes were already present in gc.h, but they weren't
3824 (scm_init_storage): Initialize scm_protects.
3825 * root.c (scm_protects): New element of scm_sys_protects.
3827 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3829 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3831 * libguile.h: Added #include "libguile/net_db.h".
3833 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3834 30 change. That file is only meant for communication between the
3835 configuration process and load.c. If code linked against libguile
3836 wants to get at the paths mentioned in libpath.h, it can call
3837 functions declared in load.h.
3839 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3841 * libguile.h: Removed #include "libguile/fdsocket.h"
3843 * net_db.c: Added #include <sys/socket.h>.
3845 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3847 * filesys.c (scm_input_waiting_p): use select in preference to
3848 FIONREAD, since the latter doesn't detect EOF.
3849 Throw error if neither select nor FIONREAD available.
3851 * socket.c (scm_connect): take a port, not a fd object.
3852 (scm_fill_sockaddr): throw an error if fam is not recognised.
3853 (scm_bind): use scm_fill_sockaddr.
3854 (scm_listen): take a port, not a fd object.
3855 (scm_accept): take and return a port. return #f in the car if
3856 address can't be got
3857 (scm_sock_fd_to_port): new procedure.
3858 (scm_socket): use scm_sock_fd_to_port.
3859 (scm_addr_vector): throw error if unrecognised address type.
3860 take an extra argument with the calling procedure name.
3861 (scm_getsockname): take a port. return #f if address can't be got.
3862 (scm_getpeername): take a port. return #f if address can't be got.
3863 (scm_recvfrom): take a port. return #f for address component if can't
3865 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3866 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3868 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3870 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3871 use separate data pointers, to allow them to be designed
3872 independently and reused.
3873 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3874 Renamed from catch_body, catch_handler, and uncaught_throw; made
3876 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3878 (scm_catch): Use the above.
3879 (scm_throw): Don't bother printing a message for an uncaught
3880 throw; we establish a default handler in init.
3881 * throw.h (scm_internal_catch): Prototype updated.
3882 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3884 (struct scm_body_thunk_data): New structure, used as data
3885 argument to scm_body_thunk.
3886 * init.c (struct main_func_closure): New structure, packaging up
3887 the data to pass to the user's main function.
3888 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3889 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3890 scm_internal_catch to establish a catch-all handler, using
3891 scm_handle_by_message. This replaces the special-case code in
3893 (invoke_main_func): Body function for scm_internal_catch; invoke
3894 the user's main function, using the main_func_closure pointer to
3895 decide what to pass it.
3896 * root.c (struct cwdr_body_data): Remove handler_proc member.
3897 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3898 (cwdr_handler): Removed.
3900 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3902 * socket.h (SCM_P): update bind prototype.
3903 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3904 include "feature.h".
3905 (scm_socket): return a port, not a file descriptor object.
3906 include "fports.h" and <unistd.h>
3907 (scm_bind): take a port, not a file descriptor object.
3908 take an extra argument for address args.
3910 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3911 INADDR_NONE, INADDR_LOOPBACK.
3913 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3915 * init.c: include net_db.h and not fdsocket.h.
3916 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3918 * Makefile.am: corresponding changes.
3919 * socket.h: renamed from fdsocket.h, fix names.
3920 * net_db.h: renamed from socket.h, fix names.
3921 * socket.c: renamed from fdsocket.c.
3922 remove _sys from procedure names.
3923 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3924 add "socket" to features list.
3925 * net_db.c: renamed from socket.c.
3926 remove _sys from procedure names.
3927 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3928 add "net-db" to features list.
3929 include "net_db.h". don't include <sys/socket.h> or
3932 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3934 * tags.h (scm_tags): Removed comma at end of last enumerator.
3936 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3938 Don't use GCC extensions to allocate space for debugging frames.
3939 (Here he goes again! Why do we put up with this?!)
3940 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3941 an scm_debug_info structure, not an in-line array of them. Add
3942 'info' member, to say how many vect elements we've used, for eval
3944 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3945 a new variable debug_info_end to mark the end of vect, instead of
3946 the address of the 'info' pointer itself.
3947 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3948 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3949 (SCM_APPLY): Explicitly allocate space for debug.vect.
3950 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3951 * stacks.c: Adjusted for new debug frame structure.
3952 (RELOC_INFO, RELOC_FRAME): New macros.
3953 (stack_depth, read_frames): Use them, and new scm_debug_frame
3954 element 'info', instead of magically knowing that eval frames have
3955 an info pointer sitting after vect.
3956 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3958 (scm_init_stacks): Formatting tweaks.
3960 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3962 Give GCC more control flow information, so it can be sure that
3963 variables aren't used uninitialized.
3964 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3965 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3966 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3967 scm_misc_error): Tell GCC that these functions never return.
3968 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3969 out the field type, call abort if SCM_ASSERT returns, to placate
3971 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3972 scm_wta ever returns. We can't handle this case anyway, and this
3973 gives the optimizer more information.
3974 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3975 scm_wta ever returns.
3977 In some cases, the code is fine, but GCC isn't smart enough to
3978 figure that out; this usually happens when one variable is only
3979 initialized and used when a particular condition holds true, and
3980 we know that condition will never change within a given invocation
3981 of the function. In this case, we simply initialize the variables
3982 to placate the compiler, hopefully to a value which will cause a
3983 crash if it is ever actually used.
3984 * print.c (scm_iprin1): Initialize mw_pos.
3985 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3986 * throw.c (scm_ithrow): Initialize dynpair.
3987 * unif.c (scm_uniform_vector_ref): Initialize cra.
3988 * struct.c (init_struct): Initialize prot.
3989 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3991 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3992 if EXPR contains no expressions.
3994 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3996 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3997 cause an infinite loop (???). So much for the algebraic
3998 equivalency of variable-sized arrays and alloca...
4000 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
4002 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
4003 a SCM boolean, not a C boolean.
4005 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
4007 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
4008 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
4009 rules for raising scm_mtrigger. Previously, unfortunate but not
4010 unlikely circumstances could result in almost constant invokation
4011 of the gc. Now, this situations should be less likely, but they
4012 are not prevented completely.
4014 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
4016 * numbers.c (scm_fuck): Procedure removed; looks like old test
4018 * numbers.h: Prototype removed.
4020 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
4022 * debug.h (scm_debug_frame): Change `vect' member from an in-line
4023 array to a pointer, to match my Nov 21 change in eval.c.
4025 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4027 * libguile.h: Added #include "libguile/backtrace.h", #include
4028 "libguile/stacks.h".
4030 * strings.c (scm_string scm_make_string scm_string_ref
4031 scm_string_set_x scm_string_equal_p scm_string_append):
4032 Bugfix according to scm patch from Aubrey Jaffer:
4033 Corrected long-standing
4034 (not (eqv? (integer->char 128)
4035 (string-ref (make-string 1 (integer->char 128)) 0)))
4036 bug found by John Kozak <jk@noontide.demon.co.uk>.
4038 * strports.c, strports.h: Make scm_eval_0str return the value of
4039 the last expression evaluated (previously, it returned void).
4041 * strports.c, strports.h: New function: scm_read_0str. Does what
4044 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4046 * simpos.c (scm_getenv): return #f if string can't be found in the
4047 environment instead of throwing an exception, for compatibility
4048 with numerous other systems.
4050 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
4052 * Makefile.am (.c.x): Use guile-snarf.
4053 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
4055 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
4057 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4059 * backtrace.c (scm_display_error_message): Made non-static, and
4060 renamed from display_error_message.
4061 * backtrace.h (scm_display_error_message): Added extern decl.
4062 * throw.c (uncaught_throw): Use it to display the error message.
4064 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
4066 * inet_aton.c: Use #if 0, not #ifdef 0.
4068 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
4070 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
4071 to convert the returned value.
4072 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
4073 the offset argument.
4075 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4077 Add new interface to catch/throw, usable from C as well as
4079 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
4080 (scm_internal_catch): New function, replaces...
4081 (scm_catch_apply): Deleted.
4082 * throw.c (scm_catch_apply): Deleted; replaced with a more general
4083 mechanism which is a bit more code, but can be used nicely from C
4084 and implement the Scheme semantics as well.
4085 (scm_internal_catch): This is the replacement; it's named after
4086 the analogous function in Emacs.
4087 (scm_catch): Reimplemented in terms of the above.
4088 (struct catch_body_data, catch_body, catch_handler): New
4089 functions, used by scm_catch.
4090 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
4091 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
4092 support for new cwdr.
4094 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
4097 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
4099 * acconfig.h: Added DYNAMIC_LINKING symbol.
4100 * configure.in: Add option and checks for dynamic linking.
4101 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
4102 dynl.h: New files for dynamic linking support.
4103 * Makefile.am (libguile_a_SOURCES):
4105 (modinclude_HEADERS): Added "dynl.h".
4106 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
4108 * init.c (scm_boot_guile_1): Call
4109 scm_init_dynamic_linking to initialize dynamic linking support.
4111 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
4113 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
4114 (as we Schemers say). It needs to be global, so that I can tweak
4115 it for the proper operation of unexec.
4116 (scm_boot_guile_1_live): New variable, see above.
4118 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
4120 * guile-snarf.sh: Removed.
4121 * PLUGIN/guile.libs: Added dependency for -lm.
4122 * acinclude.m4: Renamed from aclocal.m4.
4123 * PLUGIN/greet: Removed.
4124 * Makefile.am, aclocal.m4: New files.
4125 * configure.in: Updated for Automake.
4127 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
4129 * eval.c (scm_definedp): Use top_level_lookup_closure_var
4130 and not top_level_lookup_thunk_var.
4132 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
4134 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
4136 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
4138 * eval.c (scm_definedp): Incompatibly changed to be a builtin
4139 Scheme function, instead of syntax. Single argument is now a
4142 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4144 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
4145 scm_ra_divide): Properly terminate statements passed as arguments
4146 to IVDEP macros. (Thanks to Bernard Urban.)
4148 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
4149 with non-constant sizes. (Thanks to Bernard Urban.)
4151 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4153 It's an "eval closure", not an "eval thunk." A thunk is a
4154 function of no arguments.
4155 * root.h (struct scm_root_state): Renamed
4156 top_level_lookup_closure_var from top_level_lookup_thunk_var.
4157 (scm_top_level_lookup_closure_var): Renamed from
4158 scm_top_level_lookup_thunk_var.
4159 * root.c (mark_root): Uses changed.
4160 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
4161 * init.c (scm_start_stack): Uses changed.
4162 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
4163 Change scheme-visible name to *top-level-lookup-closure* from
4164 *top-level-lookup-thunk*.
4166 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
4168 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
4169 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
4171 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
4173 * gc.c (struct scm_heap_seg_data): Doc fixes.
4175 * gc.c (scm_gc_sweep): Empty all segments' freelists before
4176 sweeping. Then, prepend each segment's free cells to its
4177 freelist, rather than wiping out the old value. (Thanks to Marius
4180 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
4181 scm_check_freelist, scm_debug_newcell): New functions and
4182 variables, for debugging freelist problems.
4183 * pairs.h (SCM_NEWCELL): New debugging version added.
4184 * gc.h (scm_debug_newcell): Added extern declaration, used by
4185 debugging version of SCM_NEWCELL.
4187 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4189 On some systems <libc.h> conflicts with <unistd.h>, and should not
4190 be #included at all.
4191 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
4192 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
4193 * configure.in: Call it.
4194 * posix.c, filesys.c: Use its results to decide whether or not to
4196 * configure, scmconfig.h.in: Rebuilt with autoconf and
4199 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4201 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
4202 pointer to the stdio stream before calling scm_setbuf0, so the
4203 latter will be able to retrieve it. I'm surprised this didn't
4204 segfault earlier. (Thanks to Christopher Lee.)
4206 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4208 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
4211 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4213 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
4214 number of stack narrowing specifier pairs. The first specifier in
4215 a pair controls inner border, the second the outer border. A
4216 number means cut that number of frames, a procedure object means
4217 cut until that object is found in operator position in a frame.
4219 * root.c (cwdr): Bugfix.
4221 * read.c: Recording of positions disabled by default.
4223 * procs.c (scm_closure_p): New function.
4225 * posix.c (scm_tmpnam): New function.
4227 * load.c: Added #include "throw.h".
4228 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
4231 * load.c, load.h (scm_read_and_eval_x): New function.
4233 * eval.c: Renamed debug option "deval" to "debug".
4235 (scm_eval_x): `eval!' is no longer accessible from the scheme
4236 level. Motivation: We can't allow operations which introduce
4237 glocs into the scheme level. Guile's type system can't handle
4238 these as data. Use `eval' or `read-and-eval!' as replacement.
4240 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
4241 SCM_CONSP since this is a macro!; Set vframe.prev to
4242 scm_last_debug_frame instead of 0. In this way we can look
4243 "above" the virtual start stack frame if we wish.
4244 (scm_debug_hang): New function: Useful for debugging Guile in
4245 certain tricky situations. Will probably be removed later...
4247 * debug.h: Changed semantics of debug option "backtrace". This
4248 option now only indicates whether we want automatic backtrace at
4251 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4253 * ports.c: #include "filesys.h"
4254 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
4256 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
4257 Motivation: This is system specific code which is related to file
4258 I/O. It also may use select. Added code by Gary Houston to
4259 detect presence of character in stdio buffers.
4261 * libguile.h: #include "libguile/libpath.h"
4263 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4264 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4265 SCM_SITE_DIR; Install libpath.h among the other include files.
4267 * load.c, load.h (scm_sys_package_data_dir): New function.
4269 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4271 * stacks.h: Bugfix: Don't use tail-array length field as stack
4272 length field! This screwed GC.
4274 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4276 * _scm.h: Added #ifndef around definition of macros min and max.
4278 * __scm.h: Added hooks for threads to plugin to in ints protection
4279 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4280 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4281 the main code in these macros duplicated and spread over multiple
4282 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4283 SCM_THREAD_SWITCHING_CODE.
4285 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4287 * snarf.h: New file.
4288 * guile-snarf.sh: New file.
4289 * Makefile.in (inner_h_files): Added snarf.h
4290 (ancillary, install, uninstall, distclean): Added actions for
4292 (.c.x): Use guile-snarf.
4293 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4294 (gen_c_files): Note that these depend on guile-snarf.
4295 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4296 now in "snarf.h". Added #include "snarf.h" to get them.
4297 * libguile.h: Added #include "snarf.h".
4298 (Patches applied and tweaked by Jim Blandy.)
4300 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4302 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4303 standards suggest against providing prototypes for system
4304 functions. Thanks to Greg Troxel.
4306 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4308 * strports.c (scm_eval_0str): New function.
4309 #include "read.h", to get prototype for scm_read.
4310 * Makefile.in (strports.o): Update dependencies.
4311 * strports.h: New prototype.
4313 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4314 scheme name from "int?" to "integer?". It seems to do the job.
4315 * numbers.h: Rename prototype too.
4316 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4319 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4320 scm_num_eq_p): Rename these according to R4RS conventions: call
4321 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4322 to making libguile R4RS compliant without ice-9...
4324 * load.c (scm_sys_search_load_path): Search for files under all
4325 extensions listed in the %load-extensions variable. If FILENAME
4326 is absolute, return it unchanged, without searching the load path.
4327 (scm_loc_load_extensions): New variable, pointing to
4328 %load-extensions' value cell.
4329 (scm_init_load): Initialize it, and the value it points to.
4330 (scm_primitive_load_path): Improve error reporting.
4332 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4333 of new Scheme variable %load-hook.
4334 (scm_primitive_load): Apply %load-hook to filename.
4336 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4338 * configure.in: add tests for figuring out whether buffered data
4339 is available in a FILE structure, which is needed by char-ready.
4341 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4344 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4345 exceptions using misc_error instead of syserror. It seems a bit
4346 odd to throw an exception if a string can't be found in the
4347 environment, but it's consistent with open-file, stat etc.
4348 (simpos.h): remove sys_ from getenv.
4350 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4351 occurs, throw an error instead of returning errno. Return value
4353 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4355 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4357 * filesys.c (scm_stat2scm): derive file type and permissions from
4358 the stat mode and append them to the returned vector.
4359 There isn't much overhead in doing this and it avoids the need to
4360 work with S_IRUSR et al. in Scheme.
4361 Define symbols scm_sym_regular etc.
4362 (scm_init_filesys): don't intern S_IRUSR etc.
4364 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4365 and s_primitive_load_path.
4367 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4369 * error.h: don't declare error symbols. prototype for scm_misc_error.
4371 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4374 * error.c: use SCM_SYMBOL to set up error keys.
4375 scm_misc_error: new procedure.
4377 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4379 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4380 between `#!' and `!#' is ignored.
4381 (skip_scsh_block_comment): New function.
4383 * feature.c (scm_set_program_arguments): New argument, FIRST.
4384 * feature.h: Update prototype.
4385 * init.c (scm_boot_guile_1): Pass new argument to
4386 scm_set_program_arguments.
4388 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4390 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4391 (scm_boot_guile): Call scm_set_program_arguments here, later than
4392 the old initialization.
4394 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4395 initialization procedure.
4396 - Delete in, out, err arguments; there are other perfectly good
4397 ways to override these when desired.
4398 - Delete result argument; this function shouldn't ever return.
4399 - Rename init_func argument to main_func, for less confusion.
4400 - Delete boot_cmd argument; main_func is more general.
4401 -Add 'closure' argument, to help people pass data to main_func
4402 without resorting to global variables.
4403 - Abort if reentered; don't bother returning an error code.
4404 - Call scm_init_standard_ports to set up the default/current
4405 standard ports; no need to pass them to scm_start_stack.
4406 - Remove code to evaluate the boot_cmd, and start the repl; let
4407 the user do something like that in main_func if they want.
4408 - Remove code to package up a return value; main_func can do any
4410 - Call exit (0), instead of returning.
4411 (scm_start_stack): Don't initialize the I/O ports here; that's
4412 weird. Delete in, out, err arguments. Move guts to
4413 scm_init_standard_ports, scm_stdio_to_port.
4414 (scm_init_standard_ports): New function, to set up current and
4415 default standard ports.
4416 (scm_start_stack, scm_restart_stack): Make these static.
4417 * init.h (scm_boot_guile): Adjust declaration.
4418 (scm_start_stack, scm_restart_stack): Remove externally
4419 visible declarations for these.
4420 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4422 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4423 written out several times in scm_start_stack.
4424 * fports.h: New declaration for the above.
4426 * feature.c (scm_set_program_arguments): New function.
4427 * feature.h: New declaration for the above.
4429 * ports.c: Formatting tweak.
4431 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4433 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4434 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4435 for obtaining the address of a car or cdr field. Motivation:
4436 &SCM_CXR make assumptions about the internal structure of the
4439 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4440 Motivation: see SCM_CXRLOC.
4442 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4443 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4444 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4445 Motivation: Safer use. Some other macros are defined in terms of
4446 these operations. If these are defined using the SCM_SETCXR
4447 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4448 to inefficiency and an <e1> with side-effects could potentially
4449 break. Also, these particular operations are heavily utilized in
4450 the garbage collector. In unoptimized code there will be a
4453 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4454 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4455 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4456 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4457 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4458 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4459 vports.c: Cleaned up use of pairs: Don't make any special
4460 assumptions about the internal structure of selectors and
4461 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4462 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4463 (Among other things, this change makes it easier to build Guile
4464 with certain compilers which have problems with casted lvalues.)
4466 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4468 * stacks.c: Improve selection of relevant stack frames when making
4469 a stack object. Introduce one level of indirection in the stack
4470 object to make it possible to "narrow" to a certain region of the
4471 stack. This facilitates making use of more clever algorithms (not
4472 implemented) for selecting relevant frames and gives a cleaner
4473 design since selection of frames can be done independently of
4474 extraction of frames from the real stack.
4475 (scm_stack_id): Also take #t as argument which means look at
4478 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4479 Turn n_tail into an integer directly representing current number
4480 of frames in stack. Add field tail.
4482 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4484 * debug.c (scm_make_memoized): Made it available at scheme level.
4485 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4486 SCM_NIMP before applying heavier predicates in argument checking.
4487 (scm_local_eval): Also take memoized object as argument.
4489 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4490 aren't created with zero length, but should such a strange
4491 creature suddenly turn up...
4493 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4495 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4496 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4498 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4500 * variable.c (scm_make_variable): Make the name hint optional, as
4502 (anonymous_variable_sym): Renamed from variable_sym. All uses
4505 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4506 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4507 of scm_primitive_load_path was also changed to
4508 "primitive-load-path", from "%try-load-path". Callers changed.
4509 We'd like to respect the convention that a function named
4510 "try-mumble" should behave just like the function called "mumble",
4511 but return #f instead of signalling some error.
4512 * load.h: Rename prototypes.
4514 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4516 * print.c (make_print_state, grow_print_state), print.h: Modified
4517 the print state representation: Don't use a tail array for
4518 recording of circular references. Resizing of the print state
4519 structure invalidates the print state pointer. To avoid passing
4520 around an indirect print state reference to all printing
4521 functions, we instead let the print state reference a resizable
4524 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4526 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4527 Don't crash when passed an improper list terminated by a
4528 non-immediate value.
4530 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4532 Allocate data for structures on an eight-byte boundary, as
4533 required by the tagging system.
4534 * struct.c (alloc_struct): New function.
4535 (scm_make_struct, scm_make_vtable_vtable): Call it.
4536 * struct.h (scm_struct_n_extra_words): Bump to 3.
4537 (scm_struct_i_ptr): New "field".
4538 * gc.c (scm_gc_sweep): When we need to free the data, use the
4539 information stored by alloc_struct to find the beginning of the
4540 block allocated to the structure, so we can free it.
4542 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4544 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4547 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4548 (scm_debug_info): New member: id.
4550 * stacks.c: Stacks are now represented as structs; Stacks have an
4551 id given to them by `start-stack'.
4552 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4554 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4555 Changed stack representation.
4557 * debug.c (scm_procedure_name): Try procedure property `name' for
4558 compiled closures aswell.
4560 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4562 * eval.c: scm_i_name moved to gsubr.c
4563 (scm_m_define): Record names of all kinds of procedure
4564 objects. (Earlier, only closures were recorded.)
4566 * procprop.h: Added declaration of scm_i_name.
4568 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4569 (scm_make_gsubr): Record names of compiled closures.
4571 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4573 * debug.c, debug.h: Removed obsolete code.
4575 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4576 stacks.c: Renamed regs --> scm_contregs.
4578 * print.c (scm_free_print_state): Cleanup print state before
4579 returning it to pool. It is better to do it here than in
4580 scm_prin1 since scm_prin1 is called often.
4582 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4583 s_set_source_property_x): Check that first argument is a pair or a
4586 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4587 scm_i_line, scm_i_column and scm_i_breakpoint global.
4589 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4590 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4593 * debug.h: Added debug object smob declaration and macro
4596 * configure.in: Build with backtrace.o and stacks.o if debug
4599 * Makefile.in: Added entries for new files: backtrace.c,
4600 backtrace.h, stacks.c and stacks.h.
4602 * symbols.c (scm_sym2ovcell): Fixed documentation.
4604 * _scm.h (min, max): Added.
4606 * async.c: Moved `min' macro to _scm.h.
4608 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4609 SCM_BACKTRACE_INDENT.
4611 * eval.c: Added new debug options `maxdepth' and `indent'.
4613 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4615 * print.h: Added selector SCM_PRINT_STATE.
4617 * print.c: New functions: scm_make_print_state,
4618 scm_free_print_state.
4620 * print.h: Added declarations for scm_make_print_state,
4621 scm_free_print_state.
4623 * debug.c (scm_m_start_stack): New acro.
4625 * debug.h: Small cleanup.
4627 * init.c (scm_boot_guile_1): Moved scm_init_debug below
4630 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

4650 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
4651 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
4652 declare functions with prototypes. (Patch thanks to Marius
4655 More prototype-related changes from Marius Vollmer:
4656 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4657 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4658 * ports.h (ptobfuns): Added prototypes. This means some casting in
4660 * fports.c: Added casts for initializations, since the functions
4661 are defined to take FILE * as their stream argument, not SCM.
4662 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4663 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4664 to `char *str_data' to conform to prototype.
4666 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4668 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4670 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4672 * stime.c, stime.h: use SCM_P method.
4674 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4676 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4677 be given at least two arguments. Insist that lst's last element
4678 be a list, but don't make any requirements of its predecessors.
4680 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4682 * eval.c (scm_nconc2last): Revert last change; there seems to be
4683 other stuff going on here.
4685 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4687 * eval.c (scm_nconc2last): Make sure that each element of lst
4688 (which is a list of argument lists, except for the tail) is a
4689 proper list, i.e., finite and terminated by '().
4691 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4693 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4696 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4697 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4700 * vectors.c (scm_make_vector): Fill vectors with the undefined
4701 value, to help make Guile Scheme code more portable to other
4704 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4705 * symbols.h, tags.h: Doc fixes.
4707 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4709 * async.c (scm_take_signal): Doc fixes.
4711 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4713 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4714 want to subtract it from the modulus; we just want to leave it
4717 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4719 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4722 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4724 * throw.c (scm_catch_apply): Finished implementation of
4727 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4729 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4731 (scm_init_filesys): set "i/o-extensions" feature.
4734 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4736 * Makefile.in (root.o): Correct dependencies.
4738 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4740 * Makefile.in: Added dependency entry for root.o.
4742 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4743 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4745 * init.c (scm_start_stack): Set initial root continuation number
4748 * procs.c: New function: scm_thunk_p.
4750 * procs.h: Added declarations of scm_thunk_p.
4752 * root.c: Renamed `call-with-new-root' -->
4753 `call-with-dynamic-root'.
4754 (cwdr): Removed allocation of new root state. This should be done
4755 separately by use of scm_make_root.
4756 (scm_apply_with_dynamic_root): New function: Does what it
4757 sounds like. Needed when spawning threads.
4759 * root.h: Added member last_debug_frame to root state.
4760 Added #include "libguile/debug.h"
4762 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4763 arguments. The motivation is that code in root.c needs catch
4764 functionality, and we want to avoid code duplication.
4765 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4766 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4767 handlers that run without popping the stack into the dynwind
4770 * throw.h: Added prototypes for scm_catch_apply and
4773 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4775 * root.h (scm_root, scm_set_root): Decouple thread support details
4776 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4777 SCM_SET_THREAD_LOCAL_DATA.
4779 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4780 and tortoise scanning loop.
4782 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4784 * Makefile.in: Rebuild dependencies.
4786 * libguile.h: #include "libguile/print.h" before "smob.h", since
4787 the latter uses the print_state structure.
4789 * throw.c (scm_ithrow): Use the correct variable when checking to
4790 see if a given element of scm_dynwinds is a valid catch.
4792 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4793 structure, abort; don't just silently ignore the garbage.
4795 * _scm.h: #include "print.h" here, since it seems to be used just
4797 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4798 strports.c, unif.h: Don't #include "print.h".
4800 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4802 * feature.h (scm_loc_features): Removed external declaration.
4803 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4805 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4807 * feature.c (scm_init_feature): Added threads feature (needs to be
4808 initialized here, since features doesn't exist when
4809 scm_init_threads is called).
4811 * libguile.h: Added #include "libguile/../threads/threads.h".
4812 (This is a kludge to get thread support working. This should be
4815 * configure.in, acconfig.h: Added flags for thread support.
4817 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4820 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4821 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4824 * _scm.h: Added conditional #include "threads.h"
4826 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4827 SCM_THREADS_SWITCHING_CODE.
4829 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4830 allocate the basic dynamic root object.
4831 (scm_boot_guile): Added call to scm_init_root.
4833 * root.c, root.h: Added root smob.
4834 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4835 functions: Implements dynamic roots mostly according to spec in
4836 SCM manual. Main difference is that the second argument is a
4837 throw handler rather than an error "thunk".
4839 * root.h: Added declaration of scm_init_root.
4841 * root.c: Added #include "genio.h", #include "smob.h", #include
4842 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4844 (scm_init_root): Added #include "root.x".
4846 * throw.c: Added #include "stackchk.h"
4847 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4848 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4849 can be used in scm_call_with_new_root; Added reenabling of stack
4850 checking when catching a throw.
4852 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4854 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4856 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4857 element is not found, as per R4RS.
4859 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4861 * list.c: Doc fixes throughout.
4863 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4865 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4866 declare the char * to be const. Avoids a warning in rgx.c.
4868 * ports.h: spelling fix.
4870 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4873 * load.c (scm_sys_try_load_path): throw an error if file not found
4874 (like it says it in NEWS).
4876 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4878 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4879 PROPS slot to '(), not #f; it's an empty alist.
4881 * throw.h, throw.c: Use SCM_P instead of #if hair.
4883 Remove special support for uncaught throws; see throw.c for
4885 * throw.c (uncaught_throw): New function.
4886 (scm_ithrow): Call uncaught_throw if we don't find a throw
4887 target; don't mess with scm_bad_throw_vcell.
4888 (scm_bad_throw_vcell): Variable deleted.
4889 (scm_init_throw): Don't initialize it.
4891 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4894 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4896 * numbers.c (scm_istr2int): If the number is short (as most
4897 numbers are), just call scm_small_istr2int to deal with it.
4898 (scm_small_istr2int): New function, created by un-#ifdefing the
4899 non-bignum version of scm_istr2int and renaming it.
4901 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4903 * load.c (scm_sys_try_load): don't check whether value returned
4904 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4905 Change the Scheme name from %try-load to primitive-load.
4907 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4908 Can avoid passing a message, allowing it to be derived in the
4909 error handler (e.g., if we want to throw to the key both from
4912 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4914 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4915 references now have a new appearance which is more compact and
4916 also gives a clue about what the target of the reference is.
4917 By setting parameters in the print state, more fancy printing can
4918 be achieved. This is used by the (not yet commited) backtrace
4921 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4923 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4926 * print.c: Added #include "struct.h". Removed function
4929 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4930 scm_iprin1. Removed prototype for scm_prlist.
4932 * arbiters.c (prinarb),
4933 async.c (print_async),
4934 debug.c (prindebugobj, prinmemoized),
4935 eval.c (prinprom, prinmacro),
4936 filesys.c (scm_fd_print, scm_dir_print),
4938 mallocs.c (prinmalloc),
4939 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4940 smob.h (scm_smobfuns),
4941 srcprop.c (prinsrcprops),
4943 unif.c, unif.h (scm_raprin1, rapr1),
4944 variable.c (prin_var): Changed argument `int writing' to
4945 `scm_print_state *pstate'.
4947 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4948 that it will be called before scm_init_print.
4950 * print.c (scm_prin1): Print states are now allocated when calling
4951 scm_prin1 and then passed around to all printing functions as an
4952 argument. A cache `print_state_pool' enables reuse of print
4954 (scm_make_print_state): New function.
4955 (scm_iprin1): Adaption to print states.
4956 (scm_iprlist): An initial "hare and tortoise" scan brings down
4957 time complexity to O (depth * N). (Better time complexity will be
4958 achieved when the printing code is completely rewritten.)
4960 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4962 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4963 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4964 it gets done whether or not the cache variable has a value.
4966 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4968 Distinguish #f and ().
4969 * __scm.h: #undef SICP.
4970 * pairs.h (SCM_EOL): Delete this definition, equating it with
4972 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4973 the value it used to have. Doc fixes, too.
4975 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4977 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4978 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4979 Lord's implementation of structs, allowing for tail arrays as
4980 described in the manual. Also fixed some bugs. (Both the interface
4981 and the implementation should be improved.)
4983 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4985 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4986 People who whish to see the source can do `(print-enable 'source)'.
4987 Removed #ifdef DEBUG_EXTENSIONS.
4989 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4991 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4992 integer (assuming for now accepting an integer is a good thing).
4994 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4995 %S will be used instead for write'ing arguments.
4997 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4998 asserts. fix a few other asserts.
4999 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
5000 scm_uniform_vector_ref, scm_array_set_x,
5001 scm_dimensions_to_unform_array): change args in
5002 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
5003 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
5004 scm_substring_fill_x): likewise.
5005 gsubr.c (scm_gsubr_apply): likewise.
5006 eval.c (SCM_APPLY): likewise.
5008 * eval.c (4 places): replace scm_everr with lgh_error or
5011 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
5012 scm_memory_error): new procedures.
5013 scm_everr: deleted. can use scm_wta, dropping first two args.
5014 scm_error: convert NULL subr to SCM_BOOL_F.
5016 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
5019 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
5022 * error.c, error.h: new error keys: scm_arg_type_key,
5023 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
5025 scm_wta: reimplement using lgh_error instead of scm_everr.
5027 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
5029 * gdbint.c: scm_lread now has one more argument.
5031 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
5032 scm_port_\1; Added mutator scm_set_port_filename_x (used when
5033 loading source from non-file ports, which, e. g., happens when
5034 using the Emacs interface).
5036 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
5039 * read.c: Added code for recording of positions of source code
5040 expressions; New functions: recsexpr, scm_lreadrecparen;
5041 _scm_make_srcprops --> scm_make_srcprops
5042 (scm_flush_ws): Removed updating of positions counters. This work
5043 is already done by scm_gen_getc
5045 * read.h: Added prototype for scm_lreadrecparen
5047 * print.c: Added #include "alist.h"
5049 * eval.c: Added #include "hash.h"
5051 * eq.c: Added #include "ramap.h"
5053 * options.c: Documentation fixes.
5055 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
5056 (scm_init_srcprop): Adjusted size of initial source-whash. Name
5057 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
5058 --> scm_make_srcprops
5060 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
5061 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
5062 function calls in the definition of the whash access macros.
5064 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
5066 * init.c (scm_boot_guile): Add level of indirection to
5067 scm_boot_guile_1() to ensure that stack base pointer is properly
5068 initialized. There was no guarantee that variable i was the
5069 highest/lowest variable on stack (i.e. the call frame of
5070 scm_boot_guile was not completely protected from gc).
5072 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
5074 * ports.h (scm_port_table): put back file_name, it will be used to
5075 support debugging. Undo related changes in fports.c, ioext.c,
5078 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5080 * ports.h (scm_port_table): remove file_name member for now, it seems
5082 * fports.c (scm_open_file): don't set file_name in PTAB.
5083 (prinfport): don't use file_name in PTAB.
5084 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
5085 * ports.c (scm_add_to_port_table): don't intialize file_name.
5086 (scm_port_file_name): remove for now.
5087 * gc.c (scm_gc_mark): don't mark PTAB file_name.
5089 * fports.h (scm_mkfile): prototype deleted.
5090 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
5092 * debug.c, unif.c: use scm_out_of_range instead of
5093 wta for range errors (ASSERT still needs work).
5095 * error.c, error.h (scm_out_of_range): new procedure.
5097 * error.c, error.h (scm_out_of_range_key): new key.
5099 * posix.c (scm_sync): #else was missing.
5101 * error.c, error.h: append _key to names scm_num_overflow and
5104 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
5105 of consing an empty list.
5106 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
5107 of macros, saves code and string space.
5108 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
5109 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
5110 lower case. Rename scm_syserror_m to scm_syserror_msg.
5111 error.h: prototypes for new procedures.
5113 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
5115 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
5117 * error.c, error.h: setup scm_num_overflow key.
5119 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
5120 Remove definition of SCM_OVSCM_FLOW.
5122 * fports.c (scm_open_file): use SCM_SYSERROR_M.
5124 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
5125 explicit message and args.
5127 * error.c, error.h, __scm.h: change system_error_sym to
5130 * error.c (system_error_sym): remove leading %% from the Scheme name
5133 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
5135 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5137 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
5138 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
5139 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
5140 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
5141 renamed. (These were introduced by unsupervised name
5144 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5146 * print.c: Added code for detection of circular references during
5147 printing. (init_ref_stack, grow_ref_stack): New functions. Added
5148 a hook for printing of closures (accessible via print options).
5149 This leads to a split of calls to scm_iprin1 into two classes:
5150 elementary print operations (e. g. the code which prints a smob)
5151 still use scm_iprin1 while top level calls (like scm_display) use
5152 scm_prin1. scm_prin1 begins by clearing the data structure used
5153 to record reference information.
5155 * print.h: Added declarations of scm_prin1 and scm_prlist.
5157 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
5159 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
5161 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
5163 * error.c (err_head): scm_iprin1 --> scm_prin1
5165 * debug.c: Adjusted header comment.
5169 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
5171 * strerror.c: Doc fix.
5173 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5175 * gdbint.c (gdb_read): Now possible to run during GC.
5176 (unmark_port, remark_port): New functions.
5178 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
5180 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
5181 of allocating a new string object. Also, increase size by
5182 the factor 2 instead of 1.5.
5184 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
5186 * __scm.h (SCM_P): Corrected to run under traditional C.
5188 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
5191 * async.c: Calls to scm_sysintern corrected.
5193 * async.h (scm_async_clock): Redundant declaration removed.
5195 * continuations.c (scm_dynthrow): Redundant declaration removed.
5197 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
5198 Definition typos corrected.
5200 * debug.h: Missing declarations of functions in debug.c added
5203 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
5204 Missing declarations to functions in eval.c added.
5206 * filesys.c: Possibly uninitialized variable rv.
5208 * gc.h (scm_object_addr, scm_unhash_name): Missing
5209 declarations of functions defined in gc.c added.
5211 * genio.c: Possible typos str_data -> wstr_data. ???
5213 * genio.c: Possibly unintended shadowing of local variable
5214 `int c' (gotos out of scope of inner `c'). ???
5216 * init.c: Uninitialized `SCM last' may be used.
5218 * ioext.h: (scm_sys_isatty_p): Typo.
5220 * list.h (scm_list_head): Missing prototype for function in
5223 * numbers.c (scm_two_doubles): Changed from extern to static
5224 (is used only within numbers.c).
5226 * numbers.h: Repeated declarations removed.
5228 * ports.h (scm_close_all_ports_except): Declaration for the
5229 function defined in ports.c added.
5231 * posix.h: Missing declarations added.
5233 * procs.h (scm_make_subr_opt): Missing declaration added.
5235 * socket.h (scm_sys_gethost): Missing declaration added.
5237 * socket.h: Redundant declarations removed (they are in fdsocket.h).
5239 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
5240 Missing declarations added.
5242 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
5244 * struct.c: Uninitialized variable `SCM answer' may be used.
5246 * unif.c (l2ra): Declaration prototype.
5248 * unif.c (scm_array_equal_p): Dummy definition removed (it is
5249 defined in ramap.c).
5251 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
5252 Redundant declarations removed (they are in ramap.h).
5254 * variable.h (scm_make_udvariable,
5255 scm_make_undefined_variable): Declaration corrected to
5256 correspond variable.c.
5258 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
5259 Missing declarations added.
5261 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5263 * Makefile.in (distclean): Don't forget to delete fd.h.
5265 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5267 * fd.h.in, tags.h: Trivial cleanups.
5269 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5270 marksweep.h just declared functions from gc.c.
5271 * gc.h, libguile.h: Don't #include "marksweep.h".
5272 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5273 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5274 dependencies updated.
5276 * libguile.h: Don't #include "files.h"; it's been deleted.
5278 * files.c (scm_sys_delete_file): Moved to filesys.c.
5279 File is now empty; deleted.
5281 * filesys.c: scm_sys_delete_file is now here. Remove
5282 #if's; they seem to rely on remnants of an old portability
5283 regimen. If the problems come up again, solve them properly,
5284 using autoconf. Specifically: Don't test M_SYSV, and #define
5285 remove to be unlink if it's #defined; don't use remove just
5286 because HAVE_STDC_HEADERS is #defined.
5287 * filesys.h: Add declarations for scm_sys_delete_file.
5288 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5289 files.o, files.h, files.c, and files.x.
5290 * init.c: Don't #include "files.h", and don't call scm_init_files.
5292 Use SCM_P instead of PROTO; the latter intrudes on the user's
5294 * params.h: Deleted; definition of SCM_P moved to...
5295 * __scm.h: ... here, where it replaces PROTO macro.
5296 * libguile.h, smob.h: Don't #include "params.h".
5297 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5298 smob.h: Fix prototypes accordingly.
5299 * Makefile.in: Update dependencies.
5300 (inner_h_files): Remove params.h.
5302 * gc.c: #include "gc.h"; every module should include its header,
5303 to let the compiler cross-check the declarations against the
5306 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5307 simpos.h: #include "libguile/__scm.h".
5309 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5311 * init.c: Don't forget to #include smob.h and init.h.
5312 * Makefile.in: Dependencies updated.
5314 * smob.h: Use PROTO instead of #if __STDC__.
5316 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5318 * __scm.h: Doc fixes.
5320 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5321 <angles>; this allows `make depends' to work properly.
5323 * libguile.h: #include smob.h and pairs.h before the others; they
5324 define typedefs used by other headers.
5326 C files should #include only the header files they need, not
5327 libguile.h (which #includes all the header files); the pointless
5328 recompilation was wasting my time.
5329 * Makefile.in (all .o dependency lists): Regenerated.
5330 * libguile.h: Don't try to get a definition for size_t here...
5331 * __scm.h: Do it here.
5332 * _scm.h: Since this is the internal libguile header, put things
5333 here that all (or a majority) of the libguile files will want.
5334 Don't #include <libguile.h> here; that generates dependencies on
5335 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5336 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5337 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5434 * weaks.c: Get "weaks.h".
5436 * stackchk.h: #include "libguile/debug.h",
5438 * print.h, read.h: #include "options.h", since everyone who uses
5439 either of these files will need that.
5441 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5442 anyone who uses this file will need them to define the smob
5443 printing functions. Also, get markers.h, since people will need
5444 to #define the mark functions.
5446 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5447 * ports.h: ... to here.
5449 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5450 don't rely on archaic C default type rules.
5452 * fports.h: #include "libguile/ports.h", since you need that in
5453 order to parse this.
5455 * genio.h: #include "libguile/print.h", because you need that to
5456 parse this; don't bother #including "ports.h", since print.h gets
5459 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5461 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5462 this; it's now a reference to an element of *scm_root.
5464 * debug.h: Don't #include "options.h"; the compiler won't be able
5465 to find that once the headers are installed; instead, #include
5466 "libguile/options.h".
5467 * gc.h: Same, with marksweep.h.
5468 * mbstrings.h: Same, with symbols.h.
5469 * scmhob.h: Same, with _scm.h.
5470 * smob.h: Same, with params.h.
5472 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5473 C files; there's no need for this, and it forces recompilations
5476 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5478 * error.c (scm_error): declare scm_error_callback.
5480 * error.h: prototype for scm_error_callback.
5482 * __scm.h: define lgh_error.
5483 (SCM_SYSERROR): redefine using lgh_error.
5485 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5487 * error.c (scm_error): new procedure.
5489 * error.h: prototype for scm_error.
5491 * Makefile.in (install): install scmconfig.h from the current
5492 directory, not $(srcdir).
5494 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5496 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5497 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5498 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
5499 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
5500 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
5501 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5502 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5503 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5504 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5505 vports.h, weaks.h: #include "libguile/__scm.h", not
5506 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5507 dependencies are within libguile properly.
5509 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5511 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5512 when scmconfig.h doesn't exist.
5514 * load.c (scm_sys_try_load): Correct spelling.
5516 * feature.c (scm_loc_features): Make this static.
5518 * Makefile.in (libpath.h): Omit trailing slash from path. We
5519 shouldn't require it of users, so why put it here?
5521 Move code to initialize and search %load-path from ice-9 to C
5522 code, so we can use the load-path to find the ice-9 boot code;
5523 this makes it easier to run Guile without installing it. See
5524 corresponding changes in guile/Makefile.in.
5525 * feature.c: Move stuff concerned with the load path to load.c.
5526 (scm_compiled_library_path): Deleted.
5527 Don't #include libpath.h here.
5528 * feature.h: Don't mention scm_compiled_library_path.
5529 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5530 <sys/stat.h>, and <unistd.h> (if present).
5531 (R_OK): #define if the system hasn't deigned to.
5532 (scm_loc_load_path): New variable.
5533 (scm_init_load_path, scm_sys_search_load_path,
5534 scm_sys_try_load_path): New functions.
5535 (scm_init_load): Initialize scm_loc_load_path to point to the
5536 value cell of the Scheme %load-path variable.
5537 * load.h: Add declarations for scm_sys_search_load_path,
5538 scm_sys_try_load_path.
5539 * init.c: Call scm_init_load_path.
5540 * Makefile.in (feature.o, load.o): Dependencies updated.
5542 * load.c, load.h: Rewrite using PROTO macro.
5544 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5546 * gc.c (scm_cellp): New function: C predicate to determine if an
5547 SCM value can be regarded as a pointer to a cell on the heap.
5549 * gc.h: Added declaration of scm_cellp.
5551 * gdb_interface.h: New file: The GDB interface header from the GDB
5554 * gdbint.c: New file: GDB interface.
5556 * gdbint.h: New file: GDB interface.
5558 * libguile.h: Added #include <libguile/gdbint.h>.
5560 * init.c (scm_boot_guile): Added scm_init_gdbint.
5562 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5563 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5564 found if object files and source are kept separate).
5566 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5568 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5570 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5572 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5573 TK_SRC_DIR; they're not relevant any more.
5575 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5576 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5578 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5580 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5581 search path, so we can find the <libguile/MUMBLE.h> headers.
5583 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5585 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5586 implicit in the .c.o rule.
5587 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5590 Put the library path in a header file, instead of passing it on
5591 the command line in every compilation.
5592 * Makefile.in (libpath.h): New target.
5593 (feature.o): Depend on libpath.h.
5594 (clean): Delete libpath.h.
5595 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5596 * feature.c: ... #include "libpath.h" here.
5597 * .cvsignore: Ignore libpath.h.
5599 Don't install the unwashed masses of Guile header files in the
5600 main #include path; put most of them in a subdirectory called
5601 'libguile'. This avoids naming conflicts between Guile header
5602 files and system header files (of which there were a few).
5603 * Makefile.in (pkgincludedir): Deleted.
5604 (innerincludedir): New variable; this and $(includedir) are enough.
5605 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5606 (installed_h_files): Divide this up. Now this variable lists
5607 those header files which should go into $(includedir) (i.e. appear
5608 directly in the #include path), and ...
5609 (inner_h_files): ... this new variable says which files appear in
5610 a subdirectory, and are referred to as <libguile/mumble.h>.
5611 (h_files): List them both.
5612 (install): Create innerincludedir, not pkgincludedir. Put
5613 the installed_h_files and inner_h_files in their proper places.
5614 (uninstall): Corresponding changes.
5615 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5616 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5617 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5618 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5619 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5620 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5621 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5622 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5623 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5624 vports.h, weaks.h: Find __scm.h in its new location.
5625 * __scm.h: Find scmconfig.h and tags.h in their new locations
5626 (they're both "inner" files).
5628 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5630 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5632 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5634 * posix.c: Doc fixes.
5636 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5638 * socket.c: Don't include a prototype for inet_aton; just use a
5639 K&R style declaration, to avoid warnings but minimize the chance
5640 of conflicts with the system.
5642 On NextStep, <utime.h> doesn't define struct utime, unless we
5643 #define _POSIX_SOURCE before #including it.
5644 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5645 * acconfig.h: New comment text for above CPP symbol.
5646 * configure.in: Call it.
5647 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5649 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5651 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5652 testing for __EMX__.
5654 * posix.c: #include <libc.h>, if it exists.
5656 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5657 don't even know if the latter exists.
5659 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5660 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5661 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5663 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5665 (scm_init_posix): Use them when initializing the Scheme constants
5668 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5670 * Makefile.in (libdir, includedir, bindir): Use the
5671 autoconf-supplied values, instead of deriving them ourselves.
5672 (pkgincludedir, datadir, pkgdatadir): New variables.
5673 (install, uninstall): Put the header files in a special
5674 subdirectory, not in the main search path.
5676 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5677 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5679 * Makefile.in (IMPLPATH): Deleted; never used.
5681 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5682 on the Tcl/Tk source any more.
5683 (INCLUDE_CFLAGS): Remove references to the above.
5685 * Makefile.in (version.o): Corrected dependencies.
5687 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5689 * libguile.h: #include "version.h"
5691 * init.c (scm_boot_guile): Call scm_init_version.
5692 * gscm.c (gscm_run_scm): Call scm_init_version.
5694 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5695 GUILE_VERSION): AC_DEFINE these.
5696 (acconfig.h): #undef the above symbols.
5698 * Makefile.in (libobjs): Add version.o.
5699 (installed_h_files): Add version.h.
5700 (c_files): Add version.c.
5701 (gen_c_files): Add version.x.
5702 (version.o): New rule.
5703 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5704 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

5712 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5713 weaks.o): Add version.h to dependency lists.
5714 (markers.o): Remove duplicate rule.
5716 * version.h: New file.
5718 * version.c: New file.
5720 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5722 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5723 array; use it appropriately. Since GCC is quite happy to
5724 subscript functions, it never warned us about this; we should use
5725 -Wpointer-arith in the future. I guess we never tested
5728 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5730 * socket.c: Doc and copyright fixes.
5732 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5734 * debug.c: Fixed and improved gdb support.
5736 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5738 * socket.c: Added declaration of inet_aton to avoid compiler
5739 warning. (Hope this solution is correct.)
5741 * stime.c: Added declaration of ftime. (This is missing in
5744 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5746 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5748 * Makefile.in (c_files): add strerror.c.
5750 * strerror.c: new file from Emacs' sysdep.c.
5751 maybe configure should also check for sys_errlist.
5753 * configure.in (AC_REPLACE_FUNCS): add strerror.
5755 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5757 * debug.c (scm_init_debug): Added initialization for
5758 scm_evaluator_traps.
5760 * debug.h, debug.c: Various name changes.
5761 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5762 "debug-options-interface". See commentary in options.c.
5764 * options.h, options.c: Options now have documentation strings.
5765 Also added a long explanatory commentary.
5767 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5770 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5771 last_debug_info_frame is now updated in all cases.
5773 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5776 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5778 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5779 Added option STACK_CHECKING.
5781 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5783 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5785 * __scm.h: Removed symbols for debugging support.
5787 * acconfig.h: Added symbols for debugging support.
5789 * configure.in: Added user option for debugging support.
5790 --enable-debug will include the debugging code into libguile.a.
5792 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5793 scm_relocate_chunk_to_heap.
5795 * debug.c: New file: low-level debugging support. It also
5796 includes support for debugging with gdb. (The extensions to gdb
5797 are written by Per Bothner at Cygnus.)
5799 * debug.h: New file: low-level debugging support.
5801 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5802 argument pairs. Extensive modifications to the debugging
5803 evaluator. Added "SECTION:" commentaries to clarify what happens
5804 when, during double compilation. Renamed EVALIMP --> EVALIM.
5805 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5806 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5807 the beginning of the file. New procedure: scm_unmemocopy.
5808 Added some global state variables needed by the debugging
5809 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5810 check_entry, check_apply, check_exit, debug_options and
5811 evaluator_traps. New acro: undefine.
5813 * eval.h: Renamed EVAL --> XEVAL.
5815 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5816 --> scm_make_weak_key_hash_table.
5818 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5819 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5821 * libguile.h: Conditionally include debug.h
5823 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5824 scm_object_properties shouldn't return handle. `handle' now gets
5825 initialized in scm_set_object_properties_x. scm_object_properties
5826 doesn't any longer create an entry in scm_object_whash.
5828 * options.c: New file: handling of run time options.
5830 * options.h: New file: handling of run time options.
5832 * posix.c (scm_getpgrp): Cast pointer to getpgrp.

5853 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5855 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5857 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5859 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5860 and should be called by the final client.
5862 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5864 * gc.h: Use the PROTO macro when declaring functions.
5865 * gc.c: Use the PROTO macro when declaring static functions.
5866 Remove the CPP hair around function definitions.
5868 * gc.c (scm_init_storage): Initialize scm_asyncs.
5870 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5871 preprocessor symbol; "__scm.h" is where it might get #defined.
5872 * __scm.h: Similar: #include <scmconfig.h> before testing
5875 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5877 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5879 * init.c (scm_boot_guile): Add init_func argument; call
5880 (*init_func) instead of calling scm_appinit; it's ucky to
5881 hard-code names for the user's procedures.
5882 * init.h (scm_boot_guile): Adjust declaration.
5884 * __scm.h (PROTO): New macro, for declaring functions with
5887 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5888 eliminate all the __STDC__ conditionals.
5889 (scm_boot_guile): Add declaration.
5890 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5891 Remove __STDC__ conditionals around function definitions; the
5892 declarations in init.h will provide the same information, more
5895 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5896 complain about it in the error message; the error message is
5897 adequate without that note, and there's nothing the user can do
5900 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5902 * Makefile.in (ancillary): Drop def.sed.
5904 * posix.c (scm_init_posix): Use numeric values, rather than
5905 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5906 F_OK. The symbols aren't available on some systems, and I'm
5907 pretty sure their values are fixed by common widespread practice.
5908 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5910 More functions unavailable on some systems.
5911 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5912 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5914 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5915 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5916 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5917 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5918 stub that signals an error as the #else.
5920 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
5922 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
5924 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
5926 * unif.c: include ramap.h.
5928 * read.c (endif): case_insensative_p renamed case_insensitive_p.
5930 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
5932 * ports.c: include sys/ioctl.h.
5934 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
5936 * configure.in: check for sys/ioctl.h.
5938 * ports.c: include <malloc.h> not "malloc.h".
5940 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5942 * fports.c: remove ttyname and tmpnam declarations.
5944 * posix.c: fewer ttyname declarations.
5946 * fports.c: include <string.h> not "string.h".
5948 * init.c, ioext.c: include string.h and unistd.h.
5950 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5952 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
5953 genio.c, simpos.c, vports.c: include string.h.
5955 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
5957 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
5959 (scm_addr_buffer_size): change type from scm_sizet to int.
5960 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
5961 from scm_sizet to int.
5963 * error.c: include unistd.h.
5965 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
5968 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
5970 * __scm.hd, def.sed: deleted.
5972 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
5974 Changes for NeXT, suggested by Robert Brown.
5975 * configure.in: Call AC_TYPE_MODE_T.
5976 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
5977 NeXT. Put header file list in alphabetical order.
5978 * configure, scmconfig.h.in: Regenerated.
5979 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
5981 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
5984 * acconfig.h: New file, providing documentation for the CPP
5985 symbols defined in configure.in
5986 * acconfig-1.5.h: Removed; superceded by the above.
5988 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
5990 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
5992 * fports.c (scm_open_file): don't return #f, throw error.
5994 * ioext.c (fileno): renamed from %fileno.
5995 (soft-fileno): deleted.
5997 * ports.c (scm_port_revealed): don't need to check for -1 from
5999 (scm_set_port_revealed_x): return unspecified, not #f.
6001 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
6003 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
6005 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
6007 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
6009 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
6011 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
6012 This is necessary on Ultrix, and doesn't hurt portability.
6014 * Makefile.in (dist-dir): New target, implementing a new dist system.
6015 (installed_h_files): Put in alphabetical order.
6016 Remove duplicate entries for markers.h and unif.h.
6017 (c_files): Remove duplicate entries for markers.c.
6018 (ancillary): Renamed from anillery; all uses changed. Remove
6019 PLUGIN; it's a directory, and needs special treatment in dist-dir.
6020 Remove all the ../doc/* files; doc/Makefile.in handles that.
6022 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
6024 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
6025 every if must have an else, or else the whole command has a
6026 non-zero exit code whenever the if's condition is false.
6028 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
6030 * posix.c: include string.h.
6032 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
6034 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
6037 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
6038 Remove leading % from scheme names.
6039 Do not return error values, call SCM_SYSERROR or similar.
6041 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
6043 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
6045 * struct.c (scm_init_struct): new file.
6047 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
6049 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
6050 (scm_list_head): added list-head for rapidly chopping argument
6051 lists off of longer lists (and similar).

6055 * objprop.c (scm_object_property): assq the cdr of the whash
6056 handle for obj, not the handle itself.
6058 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
6060 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
6061 weak hash tables last of all marking to avoid an obscure gc bug.
6062 WARNING: circular lists stored in a weak hash table will hose us.
6064 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
6066 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
6067 new functions similar to scm_substring_move_left_x and
6068 scm_substring_move_right_x.
6070 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
6072 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
6075 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
6077 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
6079 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
6081 * strports.c (scm_strprint_obj): convenience function. C for
6082 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
6084 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
6085 removed to a separate library
6087 * init.c (scm_boot_guile): copied from guile-tcl.c.
6088 Initialization specific to tcl interpreters removed.
6090 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
6092 * ports.c (scm_ports_prehistory): size malloced here doesn't
6093 matter so long as it is non-0 (got rid of "* 4").
6095 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
6097 * gscm.h: gscm_mkarray eliminated (presumably was not being used
6098 since its definition was bogus).
6100 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
6102 * mallocs.[ch]: back again (for rx at least).
6104 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
6106 * ports.c: removed functions relating to the mapping between ports
6107 and descriptors. (That stuff is unix-specific and should be collected
6108 in a separate library).
6110 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
6111 (Tom Mckay@avanticorp.com)
6113 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
6115 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
6116 handled correctly (SCM_FREEP was applied to them) -- test for
6117 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
6118 being overwritten with #f. (brown@grettir.bibliotech.com)

6138 Factored pairs.c into multiple files.
6140 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
6142 * gscm.c (gscm_run_scm): got rid of objprop.
6144 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
6146 * genio.c (scm_getc):
6147 NOTE: fgetc may not be interruptable.
6149 * procprop.c (scm_stand_in_scm_proc):
6150 NOTE: don't use a alist here.
6151 (scm_set_procedure_properties_x): fix type checking throughout this file.
6153 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
6155 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
6156 after freeing part of the port table.

6161 * vports.c (scm_make_soft_port): allocate a port table entry
6162 (possibly triggering gc) before setting the tag of the corresponding
6165 * pairs.c (scm_delq_x): never throw an error.
6167 * vectors.c (scm_make_vector): made the default vector fill argument
6168 into '() (much more useful than the previous value, "#unspecified")
6170 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
6172 * ports.c (scm_add_to_port_table): Added fields
6173 to port table entries: file_name, line_num, col.
6174 Update these in open_file, gen_getc and gen_ungetc.
6175 Added procedures to access those fields.
6177 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
6179 * procs.c (scm_make_subr_opt): new entry point for making
6182 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
6184 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
6186 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
6188 * numbers.c (scm_exact_p): This function no longer
6189 implements "integer?".
6191 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
6193 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
6194 (scm_gc_stats): return an assoc of useful data. Replaces "room"
6195 and the stats reporting formerlly built into repl.
6197 * repl.[ch]: removed.
6198 GC statistics keeping moved to gc.c.
6199 Other statistics keeping can be done from Scheme.
6200 REPLS are now written in Scheme.
6202 Wed Feb 21 10:28:53 1996 Tom Lord <lord@beehive>
6204 * cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky
6205 conservatively marked objects).
6207 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
6209 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
6211 * feature.c (scm_compiled_library_path): moved here from repl.c.
6212 This file is for stuff relating specifically to Scheme libraries
6215 * eval.c (scm_m_define): don't give warning about redefinition, don't
6218 NOTE: this should throw a resumable exception with parameters --
6219 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
6221 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
6223 * error.c: scm_warn eliminated.

6235 between the call to procedurep and use.
6237 * error.c (scm_everr):
6239 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
6242 * strports.c: don't reveal the port's string to the caller
6243 because it changes size.
6245 (stputc stwrite): check/change the strings length with interrupts
6248 * objprop.c (scm_set_object_property_x &c): use the generic
6249 hashing functions and be threadsafe.

6252 (per suggestion jaffer@gnu.ai.mit.edu).
6254 * mbstrings.c (scm_multi_byte_string): guard against argument list
6257 * strings.c (scm_make_string): loop cleanup
6259 * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer

6285 initialization to fix a race condition.
6287 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

6310 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
6311 set the multi_byte flag correctly in symbols. This is wrong.
6312 intern_obbary_soft and msymbolize should take an extra parameter.
6313 Also, weird multibyte symbols don't print correctly.
6314 The weird symbol syntax is also a bit bogus (emacs doesn't quite
