1 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3 * read.c, read.h (history-length, history-file): New read options.
4 (scm_read_options): Stifle history to history length.
6 * readline.c (read-history, write-history): New procedures.
8 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
10 * eval.h (scm_macro_eval_x): Removed declaration.
12 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
13 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
14 Renamed and made global.
16 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
17 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
19 * evalext.c, evalext.h: New files. Contain non-R5RS things
20 having to do with evaluation.
22 * evalext.c (serial-map): New procedure: Version of `map' which
23 guarantees that the procedure is applied to the lists in serial
25 (sequence->list): New syntax: Version of `begin' which returns a
26 list of the results of the body forms instead of the result of the
28 (scm_definedp, scm_m_undefine): Moved from eval.c
30 * evalext.h (scm_m_sequence_to_list): Added declaration.
32 * macros.c, macros.h: New files.
33 (procedure->syntax, procedure->macro, procedure->memoizing-macro,
34 macro?, macro-type, macro-name, macro-transformer): Moved from
36 (scm_make_synt): Moved from eval.c
38 * procs.c, procs.h (procedure-documentation): Moved from eval.c.
40 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
43 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
45 * debug.c, print.c: Added #include "macros.h".
47 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
49 This change adds the ability to use `unread-char' multiple times
50 without interspersed reads and adds the new procedure
51 `unread-string'. The change is optimized for the common case of
52 unreading a single character. This is also the reason behind the
53 choice to store characters in the port itself: in most cases no
54 extra malloc is required.
56 The amount of code in some macros in ports.h has been increased to
57 the extent that they would fit better as C functions, but, since
58 this code belongs to the port representation, such functions
59 should be placed in ports.c which would cause calls back and forth
60 between ports.c and genio.c. That is not good for performance.
61 Also, keeping them as macros allows the compiler to do some
62 optimizations which are needed to make the current interface
63 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
65 One benchmark (Guile startup time) indicates an increase of
66 loading speed of 1%. Another (reading (using `read') boot-9.scm
67 10 times) shows no change in performance.
69 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
70 made to find a beautiful solution.)
72 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
73 (SCM_TRY_CLRDY): New macro: Only clear the first unread
74 character. (SCM_CLRDY clears all.)
75 (SCM_N_READY_CHARS): New macro: Returns number of unread
76 characters in a port. Returns wrong answer if SCM_CRDYP is false.
77 (struct scm_port_table): New fields: `entry' contains port table
78 index, `cp' points to last unread char, `cbuf' is the buffer for
79 unread chars, `cbufend' points after end of the character buffer.
81 * ports.h, ports.c (scm_unread_string): New procedure.
82 (scm_grow_port_cbuf): New function.
84 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
86 (scm_generic_fgets), fports.c (local_fgets): Use a loop
87 to read unread characters. Use SCM_TRY_CLRDY instead of
90 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
92 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
94 * genio.c, genio.h (scm_ungets): New function.
96 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
99 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
101 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
102 declarations. (Thanks to Russ McManus.)
104 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
106 * numbers.c (num2long): As a software archeologist, I'm proud of
107 this finding! :) Preliminary dating suggests an almost 4 year old
108 remnant from the SCM ancestor. The sample has been removed from
109 the finding site and is now safely stored in the repository.
111 * numbers.h: Removed prototype for num2long.
113 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
115 * gh_data.c (gh_scm2doubles): Make it possible to pass result
117 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
118 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
119 * gh.h: Updated and added prototypes.
121 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
123 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
125 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
127 * guile-snarf.in: Never generate an empty file. (Thanks to
130 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
131 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
132 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
133 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
134 gh_new_procedure5_0): Specify argument types, to appease C++
135 compilers. (Thanks to Brad Bowman.)
137 Bug reports from Russ McManus:
138 * guile-snarf.in: If the CPP environment variable is set, use that
139 as the C preprocessor, instead of the preprocessor autoconf
141 * snarf.h (SCM_PROC): Cast the function pointer passed to
142 scm_make_gsubr, to satisfy C++.
144 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
145 Use the handler passed, instead of ignoring it and using
146 gh_standard_handler. (Thanks to Etienne Bernard.)
148 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
150 * ports.h: Put text after #endif in comment. (Thanks to Nicolas

173 * script.c (scm_compile_shell_switches): Define
174 use-emacs-interface in the root module, so the repl code can see
175 it. See today's change to top-repl in ice-9/boot-9.scm.
177 * filesys.c (set_element, get_element): Make sure that `element'
178 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
179 Boekemeier and Jorgen "forcer" Schaefer.)
181 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
183 * chars.c (scm_charnames): In ASCII character name table, make
184 newlines print as #\newline by default, not #\nl.
186 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
187 alphabetical order. Oh thrills. But it helps me know how far
188 along in the compilation I am.
189 * Makefile.in: Regenerated.
191 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
193 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
194 #bytes(...) to #y(...), and syntax for short vectors from
195 #short(...) to #h(...). This may seem nutty, but, like the other
196 uniform vectors, byte vectors and short vectors want to have the
197 same print and read syntax (and, more basic, want to have read
198 syntax!). Changing the read syntax to use multiple characters
199 after the hash sign breaks with the conventions used in R5RS and
200 the conventions used for the other uniform vectors. It also
201 introduces complexity in the current reader, both on the C and
202 Scheme levels. (The Right solution is probably to change the
203 syntax and prototypes for uniform vectors entirely.)
205 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
207 Don't use local_fgets on sockets; ftell doesn't work on sockets.
208 (Thanks to Jorgen "forcer" Schaefer.)
209 * ports.h (SCM_NOFTELL): New flag.
210 * fports.c (local_fgets): If it's set, use the generic fgets.
211 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
213 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
215 * script.c (scm_compile_shell_switches): Add handling of -q switch
216 (inhibit loading of user init file).
217 (scm_shell_usage): Add usage text for -q switch.
218 (scm_compile_shell_switches): Always load user init file first if
221 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
223 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
224 and is now broken under NetBSD. I can't fathom what it's trying
225 to do, so I've replaced it with something that I do understand,
226 which seems to work, and which isn't broken on NetBSD. "Progress?
227 You Decide." (Thanks to Perry Metzger.)
229 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
230 signed/unsigned comparison.
232 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
234 Warning fixes from Greg Harvey:
235 * unif.c (scm_array_set_x): initializer for pos
236 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
237 * struct.c (scm_struct_ref, scm_struct_set_x): Added
238 initializers for field_type, since EGCS so desparately wants to
240 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
241 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
242 when GUILE_DEBUG is defined.
243 * dynwind.h (scm_wind_chain): Same.
244 * ports.h (scm_pt_size, scm_pt_member): Same.
245 * print.h (scm_current_pstate): Same.
246 * procs.h (scm_make_cclo): Same.
248 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
250 Handle short and long long uniform arrays properly. (Thanks to
252 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
253 raeql_1): Add cases for scm_tc7_svect (short vectors) and
254 scm_tc7_llvect (long long vectors).
256 Change the way libguile and boot-9.scm are timestamped, to try to
257 get rid of these spurious mismatch warnings. Now both
258 libguile/versiondat.h and ice-9/version.scm are generated directly
259 by the configuration process, rather than having version.scm
260 generated directly, and libguile/versiondat.h generated by the
261 Makefile, which is generated by configure. It seems that
262 sometimes the Makefile would change, but versiondat.h depends on
263 Makefile.in, not Makefile, so it wouldn't get rebuilt.
264 * Makefile.am (versiondat.h): Target removed; this is generated
265 directly by the configure script now.
266 (BUILT_SOURCES): Remove versiondat.h.
267 * versiondat.h.in: New file, transformed by the configure script
269 * Makefile.in: Regenerated.
271 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
272 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
273 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
274 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
275 if we want to use them in a header file some day, we can. (Thanks
278 * stime.c (scm_get_internal_real_time): Do the arithmetic using
279 SCM numbers, so we won't have rollover problems; the range of a
280 signed long in milliseconds is about 25 days. (Thanks to Karl
283 Don't redefine sleep and usleep; fix this problem now.
284 * coop.c (sleep, usleep): Remove declarations; we don't use or
285 redefine these any more.
286 (scm_thread_usleep, scm_thread_sleep): New functions which do the
287 job of usleep and sleep in a thread-friendly way. We can use
288 these in the rest of Guile. Define versions for systems both with
290 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
291 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
292 we're just using it, not redefining it, we can use a K&R style
294 (sleep): Declare this, too, if the system hasn't.
295 (scm_sleep, scm_usleep): Use scm_thread_sleep and
296 scm_uthread_sleep if they're available; otherwise, just call the
298 * scmconfig.h.in: Regenerated.
300 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
302 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
304 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
306 * threads.c: Doc fix.
308 The argument type of usleep varies from system to system,
309 as does the return type. We really shouldn't be redefining usleep
310 at all, but I don't have time to clean that up before the 1.3.
311 release. It's on the schedule for afterwards. (Thanks to Julian
313 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
315 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
316 * scmconfig.h: Regenerated.
318 * simpos.c (scm_software_type): Procedure deleted. This isn't the
319 right way to handle system variation. Autoconf's approach is the
321 * simpos.h (scm_software_type): Declaration deleted.
323 * script.c (scm_find_executable): Don't test if unix is #defined
324 here; first, NetBSD doesn't #define it, and second, it's the wrong
325 way to go about these things. (Thanks to Perry Metzger.)
326 (dld_find_executable): Delete this MSDOS support code. This isn't
327 the way we want to support this; it needs to be rethunk at a
330 * genio.c (scm_do_read_line): Don't just politely check that the
331 line was either non-empty or EOF. Abort if it's empty and not
334 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
336 * scmconfig.h.in: Regenerated.
338 * libguile.h: Don't omit the dynamic linking functions. (Thanks
341 * genio.c (scm_do_read_line): Count lines correctly when the file
342 doesn't end in a newline.
344 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
346 * genio.c (scm_do_read_line): Maintain the line count correctly.
347 (Thanks to Harvey J. Stein and Greg Harvey.)
349 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
352 * numbers.c (big2str): Protect t from garbage collection until
353 we're done. (Thanks to Gary Houston.)
355 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
357 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
359 * Makefile.in: Regenerated.
361 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
362 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
365 Do magic to mix reads and writes on stdio FILE-based ports.
366 (Thanks to Christian Lynbech.)
367 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
369 (pre_read, pre_write): New functions.
370 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
371 local_fputs): Call them.
372 (local_fflush): Mark the port as ready for reading and writing.
373 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
374 flags on new port objects. This might not be accurate --- who
375 knows what state the FILE * is in when we get it --- but it won't
376 do extraneous calls to fflush or fseek, so it's no worse than the
377 behavior before this change.
378 * ports.h: Add comment.
380 Centralize the creation of port objects based on stdio FILE * in
381 fports.c; don't just throw them together anywhere.
382 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
383 what the rest of Guile wants. Don't set the revealed count;
384 that's only appropriate for stdin, stdout, stderr.
385 (scm_standard_stream_to_port): This function does set the revealed
387 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
388 not scm_stdio_to_port.
389 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
390 * fports.c (scm_open_file): Same.
391 * posix.c (scm_pipe): Same.
392 * socket.c (scm_sock_fd_to_port): Same.
393 * ioext.c (scm_fdopen): Same.
394 (scm_freopen): Moved from here to...
395 * fports.c (scm_freopen): ... here. This is really something that
396 munges the internals of an fport, so it should go here.
397 * fports.h (scm_stdio_to_port): Adjust prototype.
398 (scm_standard_stream_to_port, scm_freopen): New protoypes.
399 * ioext.h (scm_freopen): Prototype removed.
401 * filesys.c (set_element, get_element): This can work on both pipe
402 and file ports, so use SCM_FPORTP to typecheck, instead of testing
405 * scmconfig.h.in: Regenerated.
407 Change the definition of the functions in scm_ptobfuns so that
408 they get passed the port object, not the port's stream.
409 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
410 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
411 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
412 Pass the port itself to the scm_ptobs function.
413 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
414 scm_generic_fgets): Same.
415 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
416 getc_void_port, fgets_void_port, close_void_port): Just change the
417 argument names; these functions don't really do anything.
418 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
419 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
420 port as an argument, and use SCM_STREAM to get the stdio FILE *.
421 Also, use prototyped definitions, and get rid of the extra
423 (scm_fptob, scm_pipob): We don't need casts here any more.
424 * strports.c (prinstpt): Use prototype declarations.
425 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
426 and use SCM_STREAM to get the string info. Also, use prototyped
427 definitions, and get rid of the extra declarations.
428 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
431 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
432 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
434 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
435 scm_fgets, for consistency.
436 (scm_fptop, scm_pipob): References updated.
438 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
440 Include the source location in error messages for scripts.
441 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
442 stack is still there when we catch the error.
443 * throw.c (handler_message): If we are handling an error with a
444 message, then put together the proper arguments and call
445 scm_display_error, instead of scm_display_error_message. That
446 displays source location, if it can find it.
448 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
450 * gc.c (scm_unprotect_object): Change this so that calls to
451 scm_protect_object and scm_unprotect_object nest properly.
452 (scm_protect_object): Doc fixes.
454 * strings.c (scm_string_set_x): Require the argument to be a
455 writable string, not a substring or a symbol.
456 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
457 (Thanks to John Redford and Charbel Jacquin.)
459 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
461 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
463 * eval.c (safe_setjmp): Remove this misunderstanding.
464 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
467 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
469 * libguile.h: Mark these as C declarations, for compilation by C++
472 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
473 __cplusplus clause. I seriously doubt this ever worked the way
474 the author seems to have intended.
476 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
478 Utterly needless cleanups to hopelessly messy code.
479 * ports.c: Doc fixes.
480 (scm_fflush): Moved to ...
481 * genio.c (scm_fflush): ... here, amongst all the other port
482 method invocation functions.
483 * genio.h, ports.h: The prototype moves too.
485 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
487 * backtrace.c (display_error_body): The current frame does not
488 always have a parent frame; consider a function called directly
489 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
492 * alloca.c (alloca): Undo yesterday's changes, and simply call
493 malloc directly for storage, and abort if we don't get what we
494 want. The situation is much simpler --- just call malloc. Emacs
495 has bizarre/evil requirements (signal handlers might malloc unless
496 you set this global flag, so you have to set the flag around all
497 calls to malloc) which we are certainly not going to conform to,
498 so we can do the simple and obvious thing.
500 * coop.c (coop_condition_variable_wait): Make this function
501 static. It's only useful internally --- you should never just
502 wait on a condition variable.
503 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
505 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
507 * unif.c (scm_array_set_x): Accept any kind of number as an
508 element for a uniform vector of doubles. This is more consistent
509 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
511 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
512 works; I can't conveniently test it myself. (Thanks to Dvid
513 Tillman for the bug report.)
517 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
518 from here, not from scm_compile_shell_switches (which is a pretty
519 dumb place to do it).
520 (scm_load_startup_files): New function.
521 (scm_ice_9_already_loaded): Variable moved to here from script.c.
522 * script.c (scm_compile_shell_switches): Don't load the startup
524 (scm_ice_9_already_loaded): Variable moved.
525 * init.c (scm_load_startup_files): Prototype for new function.
526 * gh_init.c (gh_enter): Doc fix.
528 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
530 Some anti-warning changes from Greg Harvey.
531 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
532 warnings when it doesn't understand our NORETURN declarations in
534 * posix.c (scm_mknod): Similar.
536 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
538 * posix.c (scm_getpwuid): If we can't find an entry, return our
539 own message, instead of using scm_syserror --- the getpwMUMBLE
540 functions don't set `errno' to anything interesting.
542 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
544 Get rid of warnings from the cooperative threading system.
545 * threads.h (scm_single_thread_p, scm_yield,
546 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
547 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
548 scm_wait_condition_variable, scm_signal_condition_variable): Add
549 prototypes for these Scheme-visible functions.
550 * coop-defs.h (coop_next_runnable_thread,
551 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
552 Prototypes for these here, even though they're from iselect.c.
553 (coop_condition_variable_wait, coop_join): Add prototypes.
554 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
555 scm_threads_free_condvar): Make these smob functions static.
556 * coop-threads.h (coop_init): Give this a real prototype.
557 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
558 (coop_next_runnable_thread): No need to provide prototype; it's in
561 * scmconfig.h.in: .detarenegeR
563 * iselect.c, threads.c: Doc fixes.
565 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
567 * Makefile.in: Regenerated with a patched automake, to get
568 dependency generation right when using EGCS.
570 * inet_aton.c (inet_aton): Add prototype, to remove compiler
571 warning. (Thanks to Robert Pluim.)
573 * inet_aton.c (inet_aton): Reassure the compiler that the
574 arguments to the <ctype.h> macros are all unsigned characters, not
577 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
579 Getting rid of more warnings...
580 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
581 today's change to ../configure.in.
582 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
583 * scmconfig.h.in: Regenertaded.de.,.__
584 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
585 (scm_localtime, scm_mktime): Use a const char * to manipulate the
588 * readline.c: Doc fix.
589 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
590 * readline.h (scm_filename_completion_function): Add prototype.
591 (scm_init_readline): Make this into a prototype.
593 * readline.c (scm_filename_completion_function): Use SCM_PROC to
594 declare this, instead of calling scm_make_subr manually.
596 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
598 * readline.h (scm_init_readline): Add prototype for this.
599 (scm_init_readline): Make this a real prototype.
601 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
603 Warning fixes from Maciej Stachowiak:
604 * backtrace.h (scm_display_application, scm_backtrace): Add
606 * debug.c (scm_m_start_stack): Make this function static.
607 * fluids.h (scm_fluid_p): Add prototype.
608 * procprop.c (scm_i_procedure_arity): Make this function static.
609 * regex-posix.c (scm_regexp_error_msg): Make this function static.
610 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
611 * root.h (scm_dynamic_root): Add external prototype.
612 * scmsigs.h (scm_usleep): Add external prototype.
613 * script.h (scm_init_script): Use prototype, not K&R decl.
614 * stacks.h (scm_stack_id): Add external prototype.
615 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
617 1998-09-30 Mark Galassi <rosalia@cygnus.com>
619 * gh.h: took out the definitions of vset and vref, since they are
620 replaced by the proper vector routines that correspond to the R4RS
623 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
625 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
626 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
627 third argument, a C expression that should result in a SCM value,
628 which is used to initialize the variable. Reimplemented
629 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
632 * version.h (scm_libguile_config_stamp): Add prototype.
633 (From Maciej Stachowiak.)
635 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
637 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
638 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
640 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
642 * print.c (scm_iprin1): Rather than having one i, and using it in
643 several places, declare a fresh i local to each block where it is
644 used, and give it a signedness appropriate to its use in each case.
647 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
650 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
651 signed/unsigned clashes.
653 * posix.h (scm_tmpnam): Added prototype.
655 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
656 scm_make_subclass_object): Add external prototypes.
658 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
659 comparison is okay here.
661 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
663 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
664 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
666 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
669 * load.c (swap_port): Make this function static.
671 * load.c (scm_search_path): Make max_path_len and max_ext_len
672 unsigned, since they're compared against string sizes.
674 * load.c (init_build_info): Make i unsigned.
676 * ioext.h (scm_read_line): Add prototype.
678 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
679 scm_hash_fn_remove_x): Make hash bucket index local variable k
680 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
681 accurately as possible.
683 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
684 comparisons, and range checking to make sure those casts are
687 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
688 signed/unsigned comparisons.
690 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
691 avoid signed/unsigned comparisons.
692 * smob.h (scm_numsmob): Change extern declaration to match.
694 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
695 avoid signed/unsigned comparisons.
696 * ports.h (scm_numptob): Change extern declaration to match.
697 (scm_current_load_port, scm_set_port_line_x,
698 scm_set_port_column_x): New prototypes.
700 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
701 test code, and it causes warnings.
703 * gh.h (gh_int2scmb, gh_uniform_vector_length,
704 gh_uniform_vector_ref): Added prototypes.
706 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
707 debugging support unconditionally. That's backtrace.c, stack.c,
708 debug.c, and srcprop.c.
709 (EXTRA_libguile_la_SOURCES): Omit those from here.
710 * Makefile.in: Regenerated.
712 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
714 * options.c (scm_options): Bugfix: Allow empty list of options!
716 * debug.c, debug.h (scm_single_step): Removed.
717 (scm_with_traps): New procedure. This procedure could easily be
718 written in Scheme but needs to be highly optimized.
720 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
722 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
723 Check SCM_TRAPS_P before trapping.
725 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
727 Changes to avoid signed/unsigned comparison warnings.
728 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
729 (scm_gc_sweep): Make n and j local to the blocks they're used in,
730 so they can have appropriate types for each application. Make i
731 signed. Use initializers in some spots. I'll probably pay for
733 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
734 (scm_must_realloc): Make nm unsigned.
735 (init_heap_seg): Make new_seg_index and n_new_objects signed.
736 (scm_init_storage): Use prototype-style definition, and make the
738 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
739 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
741 * filesys.c (scm_readlink): Make local vars rv and size ints, to
742 avoid signed/unsigned comparison warnings, and because the return
743 value of readlink may be -1. Don't bother casting the third
744 argument to readlink.
746 * filesys.c (scm_dirname, scm_basename): Move these to their own
747 page, at the end of the file.
748 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
750 * eval.h (scm_eval_options_interface): Add external prototype for this.
751 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
753 * eval.c (scm_lookupcar1): Make this static.
755 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
756 Make these prototype declarations, not K&R-style.
758 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
759 unsigned comparison warning.
761 * appinit.c: File removed. It had a single function in it, empty,
762 whose reason for existence is explained in no documentation or
763 comment. I think it's there as a default for some Tcl-style
764 initialization, but Tcl abandoned that approach a while ago.
765 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
766 (BUILT_SOURCES): Remove appinit.x.
767 * Makefile.in: Regenerated.
769 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
771 * Makefile.in: Regenerated using the last public version of
772 automake, not the hacked Cygnus version.
774 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
776 Remove Totoro kludge.
777 * Makefile.in, scmconfig.h.in: Regenerated.
778 * init.c, readline.c: Don't check if TOTORO is #defined.
780 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
782 * Makefile.am: Adjust for new thread configuration system.
783 (INCLUDES): Include the value of THREAD_CPPFLAGS.
784 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
786 (THREAD_LIBS): Definition deleted; automake will generate such
787 things automatically.
788 * Makefile.in: Regenerated.
790 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
792 Simplify smob and port marking; set the mark bit in the generic
793 marking code, and make marker routines only responsible for
794 turning up outgoing pointers.
795 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
796 before calling the marking function. Don't call the marking
797 function if it's zero.
798 * markers.c (scm_mark0): Just return #f. This function isn't
799 necessary at all now, but it's harmless to call it. We'll leave
800 it in so other folks' code doesn't croak at link time.
801 (scm_markcdr): Don't call SCM_SETGC8MARK.
802 * async.c (mark_async): Don't call SCM_SETGC8MARK.
803 * dynl.c (mark_dynl_obj): Same.
804 * root.c (mark_root): Same.
805 * srcprop.c (marksrcprops): Same.
806 * unif.c (markra): Same.
807 * variable.c (scm_markvar): Same.
808 * ports.c (scm_markstream): Same.
809 (void_port_ptob): Specify zero for our marking function.
810 * debug.c (debugobjsmob): Same.
811 * dynwind.c (guardsmob): Same.
812 * filesys.c (dir_smob): Same.
813 * fluids.c (fluid_smob): Same.
814 * fports.c (scm_fptob, scm_pipob): Same.
815 * mallocs.c (mallocsmob): Same.
816 * regex-posix.c (regex_t_smob): Same.
817 * smob.c (freecell, flob, bigob): Same.
818 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
819 * throw.c (jbsmob, lazy_catch_funs): Same.
821 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
823 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
824 scm_copy_tree on code in order not to let memoized code to leak
825 out. Thus, scm_copy_tree needs to copy vectors as well since
826 quasiquote can introduce evaluated code also inside vector
829 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
831 * eval.c (scm_copy_tree): Removed ability to copy vectors.
833 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
834 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
837 * unif.c: Say that ivect and uvect are of type signed and unsigned
838 long instead of int in commentary so that it correctly describes
841 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
843 * stime.c: Removed declaration of strptime. (It should be
844 declared by the system headers. If it turns out that some systems
845 don't, we'll handle that then.) (Thanks to Greg Troxel.)
847 * stime.h: Renamed TIMEH --> STIMEH
849 * backtrace.c (scm_display_error, scm_display_backtrace): In order
850 to increase portability, don't use structure assignment.
851 (Thanks to Nicolas Neuss.)
853 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
855 (finalize_fd_sets): Added empty statement after last case label.
856 (Thanks to Nicolas Neuss.)
858 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
861 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
863 * init.c, readline.c: OK, I won't have these readline.x bug
864 reports anymore. We've had them since April. The current reason
865 is a completely unintelligible failure of totoro.red-bean.com to
866 do the test for rl_getc_function in libreadline correctly. This
867 kludge overrides the test if we're on totoro so that the snapshot
868 generation process can work.
870 * readline.c: Define a strdup replacement if not existent on system.
872 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
874 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
875 This change makes scm_make_vector R5RS compatible. We cannot keep
876 the third argument since people want to be able to deduce the form
877 of the C function call only by looking at R5RS. (At the same time
878 we have removed some unnecessary complexity!)
880 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
881 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
882 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
883 argument in call to scm_make_vector.
885 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
887 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
888 This macro is useful in applications.
890 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
892 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
893 (scm_parse_path, scm_search_path): New Scheme level procedures.
895 * load.h (scm_internal_parse_path, scm_parse_path,
896 scm_search_path): Declared.
898 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
900 * filesys.c (dirname, basename): New procedures.
902 * init.c (scm_boot_guile_1): Removed condition around
905 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
906 new data type (guards) for representation of C level guards and
907 data on the wind chain.
908 (scm_internal_dynamic_wind): New function.
910 * dynwind.h: Declare scm_internal_dynamic_wind.
912 * root.h (scm_root_state): Added scm_cur_loadp.
914 * root.c (mark_root): Added comment about cur_loadp.
916 * load.c: #include "dynwind.h";
917 (scm_primitive_load): Use scm_inner_dynamic_wind to update
920 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
922 * ports.c (current-load-port): New procedure.
924 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
926 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
927 not a tty, return #f.
929 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
930 to Julian Satchell and Roland Kaufmann.)
932 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
933 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
935 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
937 * debug.h, debug.c (scm_start_stack): New function. Implements
938 the guts of old scm_m_start_stack.
940 * debug.c (scm_m_start_stack): Use scm_start_stack.
942 * init.c (scm_start_stack, scm_restart_stack): Renamed to
943 start_stack and restart_stack. (These have static scope.)
945 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
947 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
948 readline functions to come in release 2.3. (Thanks to Chet
950 (handle_errors): Use the above functions.
952 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
954 * readline.c: Improvements for readline support: Handle errors
955 better; Implement before-read-hook.
957 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
959 * init.c (scm_boot_guile_1), readline.c: Test for
960 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
961 assure that we have version >= 2.1.)
963 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
965 * readline.c (scm_readline): Defer interrupts while we're calling
968 * readline.c (scm_add_history): Bugfix: Do strdup before giving
969 away the string to add_history.
970 (completion_function): Do completion for readline. (Thanks to
972 (scm_filename_completion_function): New procedure: Filename
974 (current_input_getc): New function. Use this one instead of
975 standard getc from readline.
977 * throw.c, throw.h (scm_handle_by_throw): New function: This
978 handler throws errors to next handler on the dynwind chain.
980 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
982 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
985 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
987 * procprop.c (scm_i_procedure_arity): New function. Returns arity
989 (scm_procedure_properties): Modified to return arity together with
991 (scm_procedure_property): Added the read-only property `arity'.
992 (scm_set_procedure_property_x): It is an error to set the `arity'
995 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
996 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
998 * procprop.h (scm_sym_arity): New symbol.
1000 * objects.c (scm_set_object_procedure_x): New procedure: Use this
1001 to set the dispatch procedure of an operator or entity object.
1003 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
1004 Made procedure slots read-only.
1006 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
1007 scm_tcs_cons_gloc case in zero args switch; Fixed args
1008 construction for operators in scm_tcs_cons_gloc case in two args
1011 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1013 * fluids.c: Removed use of assert.h (in order to avoid
1016 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
1018 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
1020 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
1021 change makes the evaluator safer at the cost of evaluation speed.
1022 It handles the case when the user has added a non-immediate
1023 improper end of the application form, e.g., `(+ 0 . x)'.
1024 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
1025 minimize the extra cost as much as possible. The new code is
1026 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
1027 problem with structs planted directly in the code (e.g. by a
1028 macro). This no longer causes segmentation fault. (Thanks to
1031 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
1032 arg `proc' in order to be able to throw errors; New argument
1035 * Removed extra #include "debug.h"
1037 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
1039 * scmsigs.c: Declare usleep as returning void on some systems.
1040 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
1043 * coop.c (usleep): Return void on some systems.
1045 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1047 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
1049 * coop.c: Changed return type of usleep to int.
1051 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
1052 isn't found in the OS.
1054 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
1055 isn't enabled. (Thought that I had made this change ages ago...)
1057 * iselect.c: Declare bzero if not defined by OS.
1059 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1061 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
1062 condition. (Thanks to John Tobey.)
1064 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
1065 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
1068 * __scm.h: Start the long-term project of moving to POSIX threads.
1069 Phase 1: Classification of all critical sections.
1070 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
1071 for A sections. (See comments in __scm.h for details.)
1073 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
1074 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
1076 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1078 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
1079 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
1080 (libpath.h, versiondat.h): Replaced dependency on Makefile with
1081 dependencies on $(srcdir)/Makefile.in
1082 $(top_builddir)/config.status in order to avoid circularity.
1084 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
1085 from argc if argc was 0 initially.
1087 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
1088 in generation of libpath.h.
1090 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
1092 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
1093 libguile from 2 to 3.
1095 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
1097 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
1099 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
1101 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
1102 scm_set_port_column_x, scm_port_filename,
1103 scm_set_port_filename_x): Removed optional arguments. Added
1104 proper argument checking.
1106 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
1107 stack size in machine words.
1109 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
1110 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
1111 to Ole Myren Röhne.)
1113 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
1115 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
1116 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
1118 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
1121 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
1122 procedure apply: Copy argument lists before pushing them unto the
1123 environment so that the environment won't get mutated due to
1124 manipulation of procedure arguments. This should perhaps be
1125 regarded as a temporary solution until someone finds a more
1126 efficient one. (Thanks to Maciej Stachowiak.)
1128 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
1130 * script.c (scm_compile_shell_switches): Use "guile" as default
1131 zero arg if argc is NULL.
1133 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
1135 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
1136 is zero. (Thanks to Dirk Herrmann.)
1138 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
1140 * ports.c (scm_add_to_port_table): First line is now line 0
1141 (was 1). (Interface changed according to suggestion by Per
1144 * backtrace.c (display_header): Add 1 to line and column numbers
1145 when presenting them to the user.
1147 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
1148 from debug.c --> eval.c
1150 * eval.h, eval.c (scm_eval_options_interface): New options
1152 (SCM_EVAL_STACK): New option: Size of newly created stacks,
1153 i.e. stacks for new threads.
1155 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
1157 * eval.c (unsafe_setjmp): Removed with #if 0.
1159 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
1162 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
1163 to avoid compiler warnings.
1165 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
1167 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
1169 * throw.c (handler_message): Print message on current error port
1170 instead of default error port. (Thanks to Maciej Stachowiak.)
1172 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
1174 * ports.c (scm_add_to_port_table): allocate in units of
1175 struct scm_port_table *, not struct scm_port_table.
1176 * posix.c (scm_close_pipe): remove the port from the port table
1178 Thanks to Rob Engle for both fixes.
1180 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1182 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
1183 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
1185 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1187 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
1189 * backtrace.c (display_error_body, display_backtrace_body),
1190 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
1191 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
1192 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
1193 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
1196 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
1197 don't receive the jmpbuf arg anylonger.
1198 (scm_catch): Don't accept a #f tag.
1199 (scm_throw): Check that key is a symbol.
1200 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
1202 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
1204 * async.c (async_pending): Removed declaration.
1206 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1208 * dynwind.c (scm_wind_chain): New debug function.
1210 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
1211 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
1212 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
1213 extra layer of functions around the body and handler of a thread.
1214 This extra layer makes sure that the handler is called in the
1215 dynamic context of the surround (= empty dynwind list), but under
1216 the *dynamic root* of the body. We can not use the dynamic root
1217 of the surround since that root belongs to another thread => stack
1218 is not handled correctly. It may seem ugly to use this extra
1219 layer, but the extra cost in terms of execution time is really
1220 negligible compared to the total amount of time required to create
1221 a thread, and it would reduce maintainability to duplicate the
1222 crucial and complicated steps performed by cwdr.
1224 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
1225 (SCM_ALLOW_INTS): Added thread switching code before interrupts
1226 get re-enabled. The important effect of this is that interrupts
1227 are blocked during thread switching so that thread data structures
1228 don't risk getting messed up by an unfortunate signal.
1229 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
1230 seems to do more aggressive optimization which actually move
1231 instructions around in these macros in a fatal way. Therefore:
1232 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
1233 just superstitious...)
1234 (SCM_TICK): Maybe do a context switch and take care of asyncs.
1235 This macro should be used instead of SCM_ASYNC_TICK since the
1236 latter doesn't do context switches any more.
1238 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
1239 instead of SCM_ASYNC_TICK.
1241 * coop.c, iselect.c: Since thread switches are now performed with
1242 interrupts masked, we can't use the old mechanism of delivering
1243 signals immediately when they arrive. Signals must instead be
1244 delivered when the asyncs run *after* the end of the critical
1245 section in scm_internal_select. But this also means after context
1246 switch so that the signal will be delivered to a different thread.
1247 To avoid this, I have changed the protocol of
1248 coop_wait_for_runnable_thread and friends so that they are allowed
1249 to return the original thread. So, if a signal arrives during
1250 scm_internal_select, we won't any longer be forced do a context
1251 switch, but can remain in the same thread and deliver the signal
1254 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
1255 scm_asyncs_pending and made it global.
1257 * iselect.c: Small fixes.
1259 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
1260 coop_condition_variable_init, coop_condition_variable_wait,
1261 coop_condition_variable_signal): Changed return type from `void'
1262 to `int'. This is to adhere closer to the pthreads interface.
1263 This, in turn, is part of an attempt to provide C versions of the
1264 mutex and condition variable primitives which can be part of a
1265 frontend to COOP or pthreads.
1267 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
1268 coop_condition_variable_destroy): New functions.
1270 * coop-threads.c (scm_wait_condition_variable): Use
1271 coop_condition_variable_wait_mutex.
1273 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
1274 Definitions moved to coop-defs.h.
1276 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
1277 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
1278 scm_cond_destroy): New C interface to mutecis and cond vars.
1280 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1282 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
1284 * iselect.c: Now several threads can wait on the same file
1285 descriptor. The behaviour is compatible with OS select: All
1286 threads waiting for the fd return with the same status.
1288 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1290 * coop-threads.c, threads.h (scm_spawn_thread): New function.
1291 Can spawn a thread from application C code.
1293 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1295 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
1296 gh_doubles2scm): New functions.
1298 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
1300 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
1301 commented-out version of gh_eval_str()
1303 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
1305 * socket.c (scm_bind): free soka after use.
1307 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
1309 * stime.c (tzvar): new variable.
1310 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
1311 avoid memory leaks when allocating.
1313 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
1315 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
1318 * gc.c, tags.h: Doc fixes.
1320 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1322 * eval.c (macro-eval!): Removed. This function was a design bug.
1323 It allowed memoized code to leak out to the scheme level. Most
1324 things that you could do with `macro-eval!' can be done with
1327 1997-12-20 Tim Pierce <twp@skepsis.com>
1329 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
1330 scm_fgets now depends on ftell(3) to know how many bytes were
1333 1997-12-15 Tim Pierce <twp@skepsis.com>
1335 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
1336 dealing with strings.
1338 1997-12-13 Tim Pierce <twp@skepsis.com>
1340 Make %read-line more suitable for implementing read-line efficiently.
1341 * ioext.c (scm_read_line): Strip the terminating newline from a
1342 string, and return a cons of the string and its terminator.
1344 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
1345 of the string that is read is stored in this memory location.
1346 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
1347 * genio.c, genio.h (scm_do_read_line): Update caller.
1348 * ports.h (scm_ptobfuns): Update typedef.
1349 * fports.c (scm_fptob, scm_pipob): Update struct.
1351 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1353 * filesys.c (set_element): Return file descriptor.
1354 (fill_select_type): Return the highest file descriptor.
1355 (scm_select): Tell select about the highest file descriptor. On
1356 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
1357 Therefore the extra overhead for calculating the maximum fd seems
1358 to be more than compensated. Is this correct? In any case,
1359 scm_internal_select will be much faster with this info.
1360 (scm_select, fill_select_type, set_element): Don't accept any kind
1361 of object in the file descriptor list or vector.
1363 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1365 * iselect.c (finalize_fd_sets): Bugfix.
1367 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1369 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1370 when using scm_internal_select (since we might switch to another
1373 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1375 * simpos.c (scm_system): always define: use sysmissing if not
1376 available. Check for HAVE_SYSTEM instead of _Windows (does
1377 Windows lack system or does it have an unusable one?).
1378 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1379 Let the argument be optional: if not supplied, call system(NULL).
1381 * ports.c (scm_close_port): relax the type check from OPPORTP to
1382 PORTP; closing a closed port is allowed.
1384 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1386 * fports.c (scm_fgets): Return if the last char in a chunk is
1387 newline. When fgets returns a string whose length is `size-1', it
1388 is ambiguous whether a whole line was retrieved, so we must check
1389 explicitly whether a line terminator is present.
1391 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1393 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
1394 before taking the CDR. (Thanks to Harald Meland.)
1396 * filesys.c (scm_stat): Slightly optimized.
1398 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
1400 * ports.c (scm_close_port): Make sure the port is open before
1403 * guile-snarf.in: Pass args through to gcc in a way that preserves
1404 whitespace boundaries. (Thanks to Greg Badros.)
1406 1997-12-02 Tim Pierce <twp@skepsis.com>
1408 * stacks.c (scm_frame_procedure): Reverse the logic in the return
1409 statement. (Thanks to Doug Evans for pointing this out.)
1411 1997-12-01 Tim Pierce <twp@skepsis.com>
1413 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
1415 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
1417 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
1418 errno macro expansion of this field name. (errno is a C
1419 preprocessor macro on some systems.)
1421 1997-11-29 Tim Pierce <twp@skepsis.com>
1423 * iselect.c: Doc fix.
1425 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
1427 * init.c (scm_start_stack): Removed initialization of
1428 scm_the_last_stack_var.
1430 * backtrace.h: Declare scm_the_last_stack_var.
1432 * backtrace.c: Define scm_the_last_stack_var.
1434 * root.c (mark_root): Don't mark the_last_stack_var.
1436 * root.h (scm_root_state): Removed the_last_stack_var.
1438 * throw.c: Added #include "fluids.h"
1439 (ss_handler): `the-last-stack' is now a fluid.
1441 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
1442 --> the_last_stack_fluid.
1444 * backtrace.c: Added #include "fluids.h"
1445 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
1446 (scm_backtrace): `the-last-stack' is now a fluid.
1448 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
1449 after scm_init_fluids.
1451 1997-11-28 Tim Pierce <twp@skepsis.com>
1453 * iselect.c: #ifdef USE_THREADS around thread-related includes.
1455 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
1456 DLSYM_ADDS_USCORE to decide whether to add an underscore.
1458 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1460 * iselect.c (coop_next_runnable_thread,
1461 coop_wait_for_runnable_thread): Disable interrupts so that no
1462 async is executed before a potential error_revive.
1463 (scm_internal_select): Disable interrupts during the parts of the
1464 code which manipulate the sleep queue and the file descriptors.
1466 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1468 * Makefile.am: Added iselect.c and iselect.h.
1470 * coop.c (coop_qinit): Initialize fields used by
1471 scm_internal_select.
1472 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1473 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1474 replacement in iselect.c.
1475 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1476 coop_join): If GUILE_ISELECT enabled, use
1477 coop_wait_for_runnable_thread instead of
1478 coop_next_runnable_thread.
1479 (usleep, sleep): New replacements for system functions if
1480 GUILE_ISELECT is enabled.
1482 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1484 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1486 * filesys.c: Added #include "iselect.h". Moved FD-macros to
1487 iselect.h. Implement Scheme level `select' using
1488 scm_internal_select. (See NEWS.)
1490 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1492 * init.c: Call scm_init_iselect.
1494 * iselect.h, iselect.c: New files. Implements
1495 scm_internal_select. (See NEWS.)
1497 1997-11-27 Tim Pierce <twp@skepsis.com>
1499 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1500 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1501 and scm_must_free, since ultimately the string returned will be copied
1502 by scm_makfrom0str anyway. Also, read any characters that may have
1503 been pushed onto the port with scm_ungetc.
1504 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1505 * ioext.c (scm_read_line): Free string after Guilifying it.
1506 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
1508 1997-11-26 Anthony Green <green@hoser.cygnus.com>
1510 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
1512 * gh.h: Safely wrap prototypes for c++ usage.
1514 1997-11-25 Mark Galassi <rosalia@cygnus.com>
1516 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
1517 gh_repl (argc, argv).
1519 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1521 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1522 and to invoke scm_shell().
1523 (gh_launch_pad): took out the loading of boot-9.scm from here,
1524 since it is probably best to let the user control that. In fact,
1525 gh_repl() now invokes scm_shell() which does that.
1527 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1529 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()

1535 yesterday's underscore patch. (Thanks to Marius Vollmer for
1538 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
1540 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if

1551 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1552 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1554 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1556 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when

1561 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1562 * Makefile.in: Regenerated.
1564 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1566 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1567 OPORT is an `open' port, not an output port.
1569 * filesys.c (scm_close, set_element, get_element, scm_chown,
1570 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use

1576 scm_close_all_ports_except, scm_set_current_output_port,
1577 scm_set_current_error_port): Likewise
1578 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1579 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):

1587 * unif.c (scm_uniform_array_write): Likewise
1589 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
1591 Minor problems with substring-related tag changes.
1592 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1593 exactly what we want to leave in to detect substrings.
1594 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1595 * tags.h: Fix diagrams and comments describing the S tag bit;
1596 remove vestigial remarks about the D tag bit.
1597 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
1598 * strings.c: Formatting tweaks.
1600 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1601 variable first; then SCHEME_LOAD_PATH, with a warning message.
1602 (scm_parse_path): New function.
1603 * script.c: Doc fixes.
1605 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1607 Readline support, from Daniel Risacher.
1608 * readline.c, readline.h: New files.
1609 * init.c: #include "readline.h".
1610 (scm_boot_guile_1): Call scm_init_readline, if we have it.
1611 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1612 * Makefile.in: Regenerated.
1613 * scmconfig.h.in: Regenerated, after change to ../configure.
1615 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1617 * gh.h: gh_vector_set -> gh_vector_set_x
1619 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1621 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1622 with the ! -> _x mapping when going from Scheme to C.
1624 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1626 * gh.h (gh_reverse):
1634 (gh_assoc): added these gh_ functions implemented as macros.
1636 * gh_predicates.c (gh_null_p):
1637 (gh_string_equal_p): added these two missing predicates.
1639 * gh_list.c (gh_append):
1644 (gh_set_cdr_x): added these routines as I go through and try to
1645 complete the picture R4RS functions that should be mirrored in the
1648 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1650 * tags.h (scm_tc7_substring): Changed the comment and code to
1651 conform with the changes below. Folks! We have suddenly two new
1652 free tc7 codes!!! Jummy, jummy!
1654 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
1656 * Makefile.in: Rebuilt.
1657 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,

1677 (scm_tc7_mb_string): Removed.
1678 (scm_tc7_mb_substring): Removed.

1681 Don't include "mbstrings.h".
1682 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
1683 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
1685 Don't include "mbstrings.h".
1686 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
1687 (SCM_SYMBOL_SLOTS): Define as 4.

1709 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
1710 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
1712 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1714 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1716 * gh_test_c.c (c_vector_test): some improvements on the vector
1719 * gh.h (gh_vector): this used to exist but do the wrong thing.
1720 Now it (almost) does the right thing, though it takes a list
1721 instead of the individual arguments. I need to see how it could
1723 (gh_list_to_vector): added this function as a macro. Corresponds
1724 to Scheme's (list->vector ...).
1725 (gh_vector_to_list): added this function as a macro. Corresponds
1726 to Scheme's (vector->list ...).
1728 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1729 gh_vector_ref, so that it resembles the Scheme routines more.
1730 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1731 resembles the Scheme routines more.
1732 (gh_make_vector): this used to be (stupidly) called gh_vector().
1733 This is the right name, since it does the same thing as the Scheme
1734 (make-vector ...) procedure.
1736 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1738 * ports.h: #include "libguile/print.h"
1740 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
1741 Some indentation fixes.
1743 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
1744 longer a user field; New field: class_flags.
1746 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
1748 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
1750 * gh_data.c (gh_bool2scm): new function which replaces
1751 gh_int2scmb(), which is now tagged as obsolete.
1753 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1755 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1756 macros should by convention not test for NIMPness.)
1757 (SCM_COERCE_OPORT): Adjust indentation.
1759 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1760 SCM_NIMP test before SCM_PRINT_STATE_P.
1762 * struct.c, struct.h, gc.c: Renamed:
1763 scm_struct_i_layout --> scm_vtable_index_layout
1764 scm_struct_i_vcell --> scm_vtable_index_vcell
1765 scm_struct_i_vtable --> scm_vtable_index_vtable
1766 scm_struct_i_printer --> scm_vtable_index_printer
1767 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1769 * struct.c (scm_print_struct): Use new printer slot; Default
1770 printing: Also output hex code of vtable so that type identity
1771 will be indicated as well.
1772 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1773 Removed struct_printer_var; Removed struct-vtable-offset;
1774 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1775 vtable-offset-user): New constants.
1777 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
1778 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
1779 If this slot contains a procedure, use that to print structures of
1780 the type represented by this vtable.
1782 * print.c (scm_iprin1): Don't print arguments of macro
1783 transformers. (They are always: exp env.); Bugfix: Unmemoize
1784 transformer source with correct environment.
1786 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1788 Streamlining of call-with-dynamic-root:
1790 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
1791 there is now only one catch.
1792 (cwdr_outer_body): Removed.
1793 (cwdr_handler): New function.
1794 (scm_internal_cwdr): New function to perform the function of cwdr
1795 but take args that are more useful to C code. Also, the handler
1796 is now invoked *outside* of the new dynamic root, like the docs
1797 say. We no longer have to catch absolutely all errors, the caller
1798 is responsible for using a handler that does not throw, if he
1800 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1801 * root.h (scm_internal_cwdr): New prototype.
1803 Even more but risky streamlining:
1805 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1806 allocation of the jumpbuf of a root continuation. The changes
1807 below are controlled by it. They are now deactivated.
1808 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1809 the JMPBUF of the scm_rootcont to NULL before returning.
1811 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1812 when they are non-NULL.
1813 (scm_gc_mark): Likewise, mark only when non-NULL.
1815 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1816 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1818 * gc.c (scm_done_malloc): New function.
1819 gc.h (scm_done_malloc): New prototype.
1821 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
1822 (struct scm_print_state) [revealed]: New field.
1823 (scm_print_state_vtable): Make visible to the outside world for
1824 type checking purposes.
1825 (scm_valid_oport_value_p): New prototype.
1827 * print.c (scm_valid_oport_value_p): New function to check whether
1828 a certain value is acceptable as a port argument.
1829 (scm_print_state_vtable): New variable.
1830 (scm_free_print_state): Set `revealed' field to false.
1831 (scm_iprin1): Call user supplied closure printer with
1832 scm_printer_apply. Print in the traditional way when there isn't
1833 one or when it returns #f.
1834 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1835 Accept a port/print-state pair in addition to just a port.
1836 (scm_prin1): Don't return the print_state to the pool when it has
1838 (scm_printer_apply): Set `revealed' field of print_state to true.
1839 (scm_init_print): Set scm_print_state_vtable.
1840 (print_state_fluid, print_state_fluid_num): Removed.
1842 * throw.h (scm_handle_by_proc_catching_all): New prototype
1843 throw.c (scm_handle_by_proc_catching_all): New function
1845 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1847 * Makefile.in: Regenerated with automake 1.2c.
1849 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1851 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1852 was looping endlessly.
1854 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1856 * strports.c (scm_eval_string): Don't close the port.
1858 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1859 former returns a nice normal integer. (Thanks to Daniel
1862 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1864 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1865 makefile variable as a build parameter called LIBS. The
1866 build-guile program will use this, for the time being.
1867 * Makefile.in: Regenerated.
1869 Thanks to Shiro Kawai:
1870 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1871 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1874 * Makefile.in: Regenerated with automake 1.2a.
1876 * script.c (scm_compile_shell_switches): If we hit the -c or --
1877 arguments, don't set the car of (command-line) to scm_usage_name,
1878 the prettified name of the guile executable; give it the full
1879 path, the way shells usually handle $0.
1881 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1883 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1884 Scheme-level name `array-map' and renamed `serial-array-map' to
1885 `serial-array-map!'.
1887 * backtrace.c: Introduced exception handlers which now enclose
1888 `display-error' and `display-backtrace' so that error reporting
1889 won't get into infinite loops if an error occurs during displaying
1890 of the error. This can very easily happen with user supplied
1891 print call-back routines.
1893 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1895 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1896 the names `serial-array-map' and `array-map' should be removed.)
1898 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1900 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1901 Added #include "objects.h"
1903 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1904 Add #include "feature.h".
1906 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1907 (modinclude_HEADERS): Added objects.h.
1909 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1910 This test is needed at many places in the code and should be
1911 abstracted. (Motivated by the need of this test in libguiletk.)
1913 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1914 (scm_eval_string), load.c (scm_primitive_load,
1915 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1916 Use SCM_EOF_OBJECT_P.
1918 * eval.c (scm_init_eval): Add feature `delay'.
1920 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1922 * scmhob.h: Removed.
1924 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1926 * list.h (SCM_LISTn): New macros. Make list creation in C code
1927 prettier. The idea comes from STk.
1929 * sequences.h, sequences.c, append.h, append.c: Removed. These
1930 files implemented non-R4RS operations which would encourage
1931 non-portable programming style and less easy-to-read code.
1933 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1936 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1937 sequences.h, #include append.h.
1939 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1942 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1944 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1946 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1948 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1950 * eval.c: Added #include "objects.h"
1952 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1955 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1956 adjacent smob numbers.
1958 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1960 * procprop.h: Added declaration of scm_i_inner_name.
1962 * gsubr.c: New global symbol scm_i_inner_name.
1964 * debug.c (scm_procedure_name): Try procedure property
1965 `inner-name' if `name' fails.
1967 * print.c (scm_iprin1): Use scm_macro_name.
1969 * eval.c (scm_m_define): Give names to macros as well; Only the
1970 first top-level definition gives a procedure/macro a name.
1971 Otherwise confusing names can turn up in backtraces.
1972 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1973 `name'; Give names to macros as well.
1975 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1976 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1979 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1981 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
1983 (prinmacro): Removed. The code has been moved/merged into print.c
1984 in order to decrease code redundancy. We want macros to print in
1985 a way equivalent to procedures, and it would be silly to duplicate
1986 the required code. (We don't want to maintain two places.)
1987 (macrosmob): Print field is now a NULL pointer.
1989 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1990 scm_macro_transformer): New prototypes.
1991 (scm_tc16_macro): Declared.
1993 * print.c (scm_iprin1): Added code for printing of macros. Macros
1994 are now printed in a way equivalent to procedures.
1996 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1998 * procs.h (scm_closure_p): Added declaration.
2000 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2002 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
2003 Shouldn't pass "heap" as the subr name.
2005 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
2007 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
2008 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
2009 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
2010 gh_equal_p): Use SCM_NFALSEP, instead of testing against
2011 SCM_BOOL_T. Any non-false value is true.
2013 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2015 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
2016 scm_gensym): Added prototypes.

2029 specifier, since (2) or (2 . 3) would cause SEGV.
2030 (scm_transpose_array): more argument checking fixes.
2032 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
2034 * Makefile.in: Regenerated.
2036 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
2038 * Makefile.in: Regenerated, so it uses "tar", not "gtar".

2042 * error.c, error.h (scm_error_callback): Removed (see NEWS).
2044 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
2046 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or

2050 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
2051 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
2052 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,

2058 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
2060 * errno.h: prototype for scm_strerror.
2061 * error.c (scm_strerror): new procedure.
2063 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2065 * list.c (scm_list_append_x): Allow non-pair as last argument.
2066 This is consistent with the R4RS append and is probably the
2067 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
2069 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2071 * stime.h: prototype for scm_times.

2089 third argument is now optional.
2091 * posix.c (scm_execl, scm_execlp): make the filename argument
2092 compulsory, since omitting it causes SEGV.
2093 (scm_sync): return unspecified instead of #f.
2094 (scm_execle): new procedure.
2095 (environ_list_to_c): new procedure.
2096 (scm_environ): use environ_list_to_c. disable interrupts.
2097 (scm_convert_exec_args): take pos and subr arguments and
2098 improve error checking.
2100 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2102 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
2103 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
2104 argument to SCM_ASSERT. Furthermore, the name of the function
2105 should be passed as first argument when signalling
2106 SCM_WNA. (Thanks to Thomas Morgan)
2108 * gsubr.c (scm_gsubr_apply): From Radey Shouman
2109 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
2110 dispatches on the number of actual args has a default case
2111 reporting an internal error. This is a vestige from a version
2112 that mallocated a SCM vector to hold the arguments. In the
2113 current version this check is too late: if it ever happens we will
2114 have already overstepped the bounds of the array.
2116 Also, the patch [...] adds a check for too many actual arguments."
2118 mdj: Removed check for "internal programming error".
2120 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2122 * gh_io.c (gh_write): New function.
2124 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:

2137 fold in the functionality of scm_primitive_dup.
2138 (scm_primitive_dup): deleted.
2140 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
2142 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
2143 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
2144 ultrix are defined. Use setvbuf instead of setbuf.
2145 (scm_setvbuf): new procedure.
2146 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
2147 (scm_setfileno): moved from ioext.c.

2161 (scm_init_print): Initialize them.
2162 (scm_iprin): If print_state_fluid carries a print_state, use that
2163 instead of creating a new one.

2165 definitions to help with calling printer functions written in
2167 * print.h (scm_printer_apply): New prototype.

2180 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
2181 SCM_ASSERT: arg comes before pos.
2183 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2185 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied

2210 stream has been set.
2211 (scm_duplicate_port): deleted, there's now an implementation in

2264 data. (dynl_smob): Use it.
2265 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
2266 the dynamic object data below the linking of the object to avoid
2267 memory leak when the linking code throws an error. Now the code
2268 leaks a whole dynamically linked library when must_malloc throws,
2269 but that should be much less likely.
2271 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
2273 Changes to compile under gnu-win32, from Marcus Daniels:

2311 think this is left over from the (eq? '() #f) days.
2313 * read.c (recsexpr): Give this a dummy definition if
2314 DEBUG_EXTENSIONS isn't #defined.
2316 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
2318 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

2333 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2335 * simpos.h: prototype for scm_primitive_exit.

2344 turn off REG_EXTENDED.
2345 (scm_init_regex_posix): New regexp/basic symbol.
2346 (REG_BASIC): #define this if it is not already present.

2393 (cwdr_outer_body): New function, to establish the user's handler,
2394 and pass control to cwdr_inner_body.

2406 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2407 the feeling that real thread systems will not need this...
2409 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2411 Try to detect when people are using one version of libguile and a

2423 primitive definitions under their Scheme names.
2425 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2426 1:2. Helps avoid confusion between installed and uninstalled libs.
2428 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2431 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2432 backslash from definition; this should be used like: GDB_INTERFACE;

2439 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2441 * ports.h: new prototype.

2451 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2453 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2454 argument plain char *.
2455 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2457 * tag.c (scm_tag): Remove unreachable statement.
2458 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2459 top of the word, it should be unsigned.
2461 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2462 is defined, to avoid warnings; it's only used in the
2463 conflict-checking code. Which might go away anyway.
2464 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2465 conditionals; put the label definition in an #if too, to stifle
2468 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2469 ChangeLog-threads in the distribution.
2470 * Makefile.in: Regenerated.
2472 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2474 * guile-snarf.in: Changed regexp to support CPPs that insert
2475 whitespace between lexical tokens (which munges the `%%%' snarf
2478 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2480 * load.c (scm_init_load_path): Append $(datadir)/guile to
2481 %load-path, so modules do not have to be installed in Guile's
2482 current version directory.
2484 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2486 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2487 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2488 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2489 call the sysdep functions with deferred ints.
2490 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2491 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2492 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2495 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2498 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2500 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2502 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2504 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2507 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2509 * eval.c (scm_lookupcar1): New procedure to cope with a race
2510 condition during lookup (when using threads).
2511 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2512 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2515 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2517 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2518 supplied. (Change from Tim Pierce.)
2520 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2522 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2523 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2524 default and not `()'. `#f' is the canonical non-value in Scheme,
2527 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2529 * struct.c (struct_printer): New variable that holds a handle on
2530 the Scheme variable *struct-printer*. This variable can be set by
2531 Scheme code to override the printing of structures.
2532 (scm_print_struct): If struct_printer is set, call it. If it is
2533 not set, or returns #f, print the structure in the old fashion.
2534 Include "eval.h" for scm_apply.
2536 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2538 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2539 scm_struct_i_n_words to get the number of fields, not
2540 -scm_struct_n_extra_words.
2542 On the route to fancier struct printing:
2543 * struct.c (scm_print_struct): New function to print a structure.
2544 Include "genio.h" to support it. This function doesn't do
2545 anything interesting right now, but I think it should be here
2547 * struct.h: Include "print.h" and add prototype for
2549 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2550 print structures ourself.
2552 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2554 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2555 before applying the handler in case it doesn't return.
2557 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2559 * scmsigs.h, async.h: updated.
2561 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2564 * posix.c (scm_uname): interpret only negative values as an error.
2565 Solaris normally returns a positive value.
2567 * script.c (scm_compile_shell_switches): if we are not going into
2568 an interactive repl, set scm_mask_ints to zero so that asyncs can
2571 * simpos.c (scm_system): don't ignore/unignore signals around
2574 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2577 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2578 done in boot-9.scm instead.
2580 * scmsigs.c, async.c: Major rewriting of signal handling code.
2581 (scm_sigaction): new procedure.
2582 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2584 (scm_raise): return unspecified, throw error on failure.
2586 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2588 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2589 feature, to help boot-9.scm decide whether to import the regex
2592 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2594 * eval.c: Include scmconfig.h at the beginning of the file so that
2595 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2598 * regex-posix.c: #include "_scm.h" before conditionally #including
2599 <regex.h>; the former defines HAVE_REGCOMP.
2601 * regex-posix.c: #include <regex.h> conditionally, so the file is
2602 CPP'able (for dependency scanning) even on systems that don't have
2605 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2607 Add new R4RS-compliant syntax for keywords.
2608 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2609 regardless of the setting of the `keywords' read option.
2610 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2611 can be re-read no matter what the setting of the `keywords' read
2614 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2616 Add support for POSIX regular expressions.
2618 * regex-posix.c, regex-posix.h: New files. (Some code
2619 is taken liberally from rx/rgx.c in the old Guile dist.)
2621 * init.c: Include regex-posix.h.
2622 (scm_boot_guile_1): Call scm_init_regex_posix.
2624 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2625 Add regex-posix.[ch] sources.
2626 * Makefile.in: Regenerated.
2628 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2629 to do this automatically? It didn't for me, bleh.)
2631 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2633 * fports.c (print_pipe_port): New function.
2634 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2635 latter doesn't even take the right arguments.
2637 * Makefile.am: Increment shared lib revision number. I think
2638 sometimes the uninstalled Guile finds the installed shared lib;
2639 Gord says doing this might help. As things turned out, I can't
2640 say whether it does.
2641 * Makefile.in: Regenerated.
2643 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2644 passing it as the closure argument to scm_boot_guile. (Bill
2647 * ports.c (print_void_port, putc_void_port, puts_void_port,
2648 write_void_port, flush_void_port, getc_void_port, close_void_port,
2649 noop0): Use ANSI prototypes instead of K&R declarations, so the
2650 initialization of void_port_ptob gets aggressively type-checked.
2651 Fix arguments of print_void_port and write_void_port. (Bill

2685 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2687 * script.c (scm_find_executable): Use prototype-style definition
2688 here; apparently it's not quite right to have const in a prototype
2689 and then use a K&R declaration. I wonder if stuff like this will
2690 go away if we compile with -Wrequire-prototypes, or whatever that
2691 is... (Bernard URBAN)
2693 * scmhob.h: New text from Bernard URBAN.
2695 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2697 * script.c: Don't #define const on hpux. Configure takes care of
2698 this. (Thanks to Larry Schwimmer.)
2700 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2701 decide whether to #include <unistd.h>, instead of listing a bunch
2702 of systems. Don't #include stdio twice. Removed dyked-out
2703 definition of scm_find_impl_file.
2705 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2707 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2708 library version info to 1:0.
2709 * Makefile.in: Regenerated.
2711 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

2715 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2716 throw.c: Update copyright years; these files have been worked on
2717 significantly in 1997, but only had copyright years for 1996.
2718 Also, change name of copyright holder on some from Mikael
2719 Djurfeldt to Free Software Foundation; he has signed papers
2720 assigning the changes to the FSF.
2722 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2723 reason not to give the user the option.
2725 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2726 Return #f on end-of-file when scanning table (i.e. when called
2727 with no arguments). Try to catch errors, when we can.
2728 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2730 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2731 external declarations. These are useful.
2733 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2735 * posix.c: don't include <sys/select.h> or define macros for
2736 select, since they were not used in this file.
2738 * filesys.c (scm_select): make the fifth parameter microseconds,
2739 not milliseconds. let the fourth parameter be either a real value
2740 or an integer or #f. The first, second and third arguments can
2741 now be vectors: the type of the corresponding return set will be
2743 (set_element, get_element): new static procedures.
2745 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2747 * strports.c (scm_eval_string): New function.
2748 (scm_eval_0str): Trivially re-implemented in terms of
2750 * strports.h (scm_eval_string): New extern decl.
2752 * net_db.c (h_errno): Add extern decl for this.
2754 * fports.c (local_pclose): New function.
2755 (scm_pipob): Use it in the initializer here.
2758 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2759 Use a meaningful error message when signalling an error. For
2760 this, scm_gethost must check h_errno rather than errno.
2762 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2764 * Makefile.in: Regenerated, using automake-1.1p.
2766 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2768 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2769 not SCM_UNSPECIFIED.
2771 * script.c (scm_compile_shell_switches): don't append (quit) if
2773 (scm_shell): call scm_exit_status and exit on the result of the
2776 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2778 Ensure that shared substrings are handled properly when passed to
2779 a system call or other foreign function. Many thanks to Tim
2781 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2782 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2783 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2784 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

2786 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
2787 (scm_display_error_message): use RO macros when strings may be RO.
2788 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
2789 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
2790 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

2795 scm_strftime), vports.c (scm_make_soft_port): use
2796 SCM_COERCE_SUBSTR to make sure shared substrings are
2799 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2801 * error.c (scm_error): Add newline to error message.
2803 * init.c (scm_init_standard_ports): Doc fix.
2805 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2807 * dynl-shl.c: Completely replaced with new code from Bernard
2810 * script.c (scm_ice_9_already_loaded): New variable.
2811 (scm_compile_shell_switches): Use it.
2813 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2815 * filesys.c (scm_input_waiting_p): add missing third argument to
2818 * stime.c (scm_localtime): copy the result of localtime before
2819 calling gmtime in case they share a buffer.
2820 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2823 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2825 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2827 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2829 * Makefile.am (check-local): New target, which causes 'make check'
2830 to run gh_test_c and gh_test_repl, with some trivial input.
2831 * Makefile.in: Rgnrtd.
2833 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2835 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2838 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2840 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2841 sure how this was supposed to work.
2842 (scm_async_click): don't send SCM_TICK_SIGNAL.
2843 (scm_init_async): don't initialize %tick-thunk.
2845 * the following change doesn't affect the Scheme interface:
2846 gc-thunk is called at the end of garbage collection. however it's
2847 no longer implemented by pretending it's a signal.
2849 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2850 system async corresponding to scm_gc_thunk.
2851 * async.h: declare scm_gc_async.
2852 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2853 gc-thunk directly, instead of going through a signal handler.
2854 (scm_gc_async): new variable, points to the GC system-async.
2855 (scm_init_async): save the GC async as scm_gc_async instead
2856 of using system_signal_asyncs.
2857 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2859 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2861 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2862 Don't screw up if we're interrupted.
2863 * Makefile.in: Regeneradet.
2865 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2867 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2869 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2870 we're not using AM_INIT_GUILE_MODULE any more.
2871 * Makefile.in: Reneregated.
2873 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2875 Functions for finding variable bindings, grace à Tim Pierce.
2876 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2877 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2879 Get 'make dist' to work again.
2880 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2881 * Makefile.in: Regenerated, like a surry without a fringe on top.
2883 Changes for reduced Guile distribution: one configure script,
2885 * configure.in, configure: Removed.
2886 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2887 real configure script lives.
2888 * Makefile.in, scmconfig.h.in: Regenerated.
2890 * init.c: #include "script.h", to get prototype for script.c's
2893 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2895 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2896 scm_must_malloc, not raw malloc.
2898 * script.c (scm_compile_shell_switches): Dyke out debugging output
2901 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2903 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2905 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2906 system has them. Hope this is safe. Previously
2907 sys/timeb.h was included if HAVE_FTIME was defined or if
2908 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2909 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2911 * ioext.c (scm_setfileno): add missing third argument to
2912 scm_misc_error call.
2914 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2916 * eq.c (scm_equal_p): Correctly compare strings of different
2917 varieties. (Thanks to Tim Pierce.)
2919 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2921 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2922 #! block comment must occur on a line all by itself.
2924 Move most of the guts of shell command processing into libguile,
2925 so guile.c can be very small (and eventuallly auto-generated. (I
2926 mean, generated mechanically, not self-generated. Hmm.))
2927 * guile.c, script.c, script.h: New source files.
2928 * init.c (scm_boot_guile_1): Call scm_init_script.
2929 * libguile.h: #include "script.h".
2930 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2931 targets, for new executable.
2932 (libguile_la_SOURCES): Mention script.c.
2933 (modinclude_HEADERS): Add script.h.
2934 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2935 not dynamic linking is enabled. This is because we're generating
2936 executables now. Move CY_AC_WITH_THREADS call after those, so the
2937 values of cy_cv_threads_libs captures the libs chosen above.
2938 * Makefile.in, configure, aclocal.m4: Regenerated.
2940 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2941 We don't maintain this interface any more, and it just confuses
2944 * alloca.c: #include <scmconfig.h>, not <config.h>.
2945 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2946 it'll get included in disties.
2948 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2950 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2951 be distributed, because they confuse people.
2952 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2954 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>

2957 OpenBSD by default).
2958 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2959 * configure, scmconfig.h.in: Regenerated.
2961 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2963 * backtrace.c (scm_backtrace): Split message string across
2964 newlines properly. GCC is more tolerant of this than other
2967 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
2969 Merge threads directory into libguile.
2970 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
2971 threads.h: New source files.
2972 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
2973 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2975 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2976 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2977 coop-threads.c.cygnus, coop-threads.h.cygnus.
2978 * configure.in: If we're using threads, include threads.o in
2980 * _scm.h, libguile.h: threads.h lives in this directory now.
2981 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2982 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2983 currently used, but brought along for information's sake.
2984 * ChangeLog-threads: log from old 'threads' directory.
2985 * Makefile.in, configure: Rebuilt.
2987 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2989 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2992 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2994 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2996 Merge GH interface library into libguile.
2997 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
2998 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2999 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
3000 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
3002 (EXTRA_libguile_la_SOURCES): ... here.
3003 (pkginclude_HEADERS): Add variable, to get gh.h installed.
3004 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
3005 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
3006 New variables, describing how to build the gh test programs.
3007 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
3008 build the test programs, and we probably should have been linking
3009 libguile.la against them all along, to support AIX shared libs.
3010 Add cflags for threads to CFLAGS; add libs for threads to new
3011 variable THREAD_LIBS, used in Makefile.am.
3012 * ChangeLog-gh: log from old `gh' subdirectory.
3013 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
3015 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
3017 * acconfig.h: Undo change of Apr 9; including the definition of
3018 PACKAGE in the guile headers conflicts with applications' own
3020 * scmconfig.h.in: Regenerated.
3022 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

3029 when PROC is receiving no arguments.
3031 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
3033 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
3034 have S_IFSOCK. This is the case under Ultrix.
3036 * posix.c (scm_status_exit_val, scm_status_exit_val,
3037 scm_status_term_sig, scm_status_stop_sig): Modified to work with
3038 Ultrix versions of WIFSTOPPED, etc., which assume that their
3039 arguments are lvalues (hmm).
3041 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
3043 * eval.c: Doc fixes.
3045 * throw.c: Doc fixes; rearranged.
3047 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
3049 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
3051 * acconfig.h: Added entry for PACKAGE.
3052 * scmconfig.h.in: Regenerated.
3054 Changes to work with automake-1.1n, which has better libtool support.
3055 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
3056 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
3058 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
3060 * Makefile.in: Rebuild.
3062 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3064 * stime.c (scm_mktime): take an optional zone argument.
3065 (scm_localtime): check putenv return value.
3066 (scm_strftime, scm_strptime): moved from posix.c. move #include
3068 stime.h, posix.h: update prototypes.
3069 (bdtime2c, setzone, restorezone): new static procedures.
3070 (scm_mktime, scm_strftime): use them.
3071 (scm_strftime): don't call mktime before strftime. Use
3072 filltime for return value.
3073 (filltime): convert NULL zname to #f.
3074 (scm_strptime): return a count of characters consumed, not
3075 the remaining string.
3077 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3079 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
3080 (scm_mktime): likewise.
3082 Uncomment localtime and mktime.
3084 * configure.in: add AC_STRUCT_TIMEZONE.
3086 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3088 * stime.c (scm_init_stime): don't define ticks/sec.
3089 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
3090 return value problem and is still portable.)
3092 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3094 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
3095 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
3096 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
3097 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
3098 cpp_err_symbols.c): Corresponding changes.
3099 * Makefile.in: Regenerated.
3101 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3103 * posix.c (scm_putenv): don't check HAVE_PUTENV.
3104 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
3105 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
3106 * putenv.c: new file, from sh-utils 1.12.
3108 * posix.c (scm_environ): use malloc in place of scm_must_malloc
3109 since allocation isn't for Scheme objects.
3110 (scm_putenv): copy strings before placing in the environment.
3112 * stime.c (scm_current_time): throw an error if time returns -1,
3113 instead of returning #f.
3114 (scm_get_internal_real_time, scm_get_internal_real_time): use
3115 scm_long2num for return value instead of SCM_MAKINUM.
3117 * stime.h: prototypes updated.
3119 * stime.c (scm_time_in_msec): apparently unused, deleted.
3121 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
3123 * configure.in: check for gettimeofday.
3125 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
3126 which may be more usefully portable than a gettimeofday interface.
3128 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
3130 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
3132 * Makefile.in: Regenerated.
3134 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3136 * stime.c (filltime): recovered static procedure.
3137 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
3140 * posix.h: add prototype for scm_close_pipe, remove prototypes for
3141 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
3143 * posix.c (scm_mknod): split the mode argument into type and perms
3144 arguments, like the extra fields returned by stat.
3146 * fports.c (scm_pipob): set the close, free and print procedures.
3147 (scm_close_pipe): new procedure.
3149 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
3150 define them in boot-9.scm
3152 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3154 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
3155 wan't defined. Don't include fd.h.
3157 * Previously fd.h was regenerated whenever configure was run,
3158 forcing a couple of files to be recompiled.
3160 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
3161 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
3162 Check for _fileno as well as _file.
3164 * ioext.c: don't fd.h.
3165 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
3168 * Change the stratigy for getting information about errno
3169 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
3170 generating lists of symbols during the build process, which will
3171 not always work, include comprehensive lists in the distribution.
3172 To help keep the lists up to date, the "check_signals" and
3173 "check_errnos" make targets can be used.
3175 * configure.in: don't check for a command to extract errno codes.
3176 * Makefile.am: update file lists, remove errnos.list and errnos.c
3177 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
3178 check_errnos targets.
3179 (CLEANFILES): remove errnos.c and errnos.list, add
3180 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
3181 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
3182 * errnos.default: deleted.
3183 * cpp_signal.c: new file.
3184 * cpp_errno.c: renamed from errnos_get.c.
3185 * cpp_err_symbols, cpp_sig_symbols: new files.
3186 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
3187 * error.c (scm_init_error): #include cpp_err_symbols instead of
3189 * posix.c (scm_init_posix): don't intern signal symbols. #include
3192 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
3194 * strop.c (scm_i_index): allow the lower bound to be equal to the
3195 length of the string, so a null string doesn't always give an error.
3197 * posix.h: new prototypes.
3198 * posix.c (scm_status_exit_val, scm_status_term_sig,
3199 scm_status_stop_sig): new functions, as in scsh. They break down
3200 process status values as returned by waitpid.
3202 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
3204 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
3205 configure doesn't know about it.
3207 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3209 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
3211 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
3212 which defines C variables with global linkage.
3214 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3216 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
3219 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
3221 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
3222 has time to check why this doesn't work well with continuations.
3224 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
3226 * Fix shell syntax error; some shells won't tolerate
3227 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
3229 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3231 * posix.c (scm_uname): throw an error if uname fails instead
3234 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
3236 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
3239 * async.c (scm_ints_disabled): definition moved from error.c.
3241 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3243 * acconfig.h: Removed PACKAGE.
3245 * scmconfig.h.in: Regenerated.
3247 * snarf.h: g++ says it's non-portable not to specify the first
3248 argument in a varargs declaration. I introduced the first
3249 argument by using preprocessor conditionals.
3251 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
3253 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
3254 (scm_freopen): use RO string macros for filename and modes.
3255 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
3257 * posix.c (scm_getgrgid): simplify conversion of name to C string.
3258 (scm_mknod): use RO string macros for path.
3260 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
3261 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
3263 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
3264 use SCM_ROSTRINGP and SCM_ROCHARS.
3266 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3268 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
3271 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
3272 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
3273 support for byte vectors.
3275 * print.c (scm_iprin1): Limit number of vector elements printed
3276 according to pstate->length.
3278 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3280 * backtrace.c (scm_display_error_message): don't segv if message
3283 * error.h: prototype for scm_error_scm.
3285 * error.c (scm_error_scm): new procedure, reimplements scm-error
3286 in C and uses scm_error.
3288 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3290 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
3291 pointer to the Scheme variable read-hash-procedures and intern it
3292 in scm_init_read. Modify scm_read_hash_extend and
3293 scm_get_hash_procedure to use the pointer.
3295 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3297 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
3298 (SCM_KEYWORD_STYLE): defined.
3300 * read.c (scm_read_opts): add a keywords option. This isn't a
3301 boolean option, in case someone wants to add support for DSSSL
3303 Setup scm_keyword_prefix symbol.
3304 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
3306 I've left keyword support disabled by default, since it doesn't
3307 seem to break the module system and it gives R4RS standard behaviour.
3308 It can be reactivated with (read-set! keywords 'prefix).
3310 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3312 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
3313 before constructing arbiter.
3315 * eval.c (scm_m_define): Bugfix: Check that the object is a
3316 closure before setting the procedure property!
3318 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
3320 * ports.c: Removed `ungetc-char-ready?'.
3322 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
3324 * read.c (scm_init_read): intitialise scm_read_hash_procedures
3325 (idea from Mikael: make it a pair so scm_permanent object only
3327 (scm_read_hash_extend): don't call scm_permanent_object.
3328 (ideas from Mikael): if chr is already in the list, replace its
3329 procedure instead of appending it again. If proc is #f, remove
3331 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
3333 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
3335 * gdbint.c (gdb_read): update scm_lreadr usage.
3337 * load.h: update prototypes.
3339 * load.c (scm_primitive_load, scm_read_and_eval_x,
3340 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
3342 * read.h: add prototype for scm_read_hash_extend. Change args for
3345 * read.c (scm_read_hash_procedures): new variable.
3346 (scm_read_hash_extend): new procedure.
3347 (scm_get_hash_procedure): new procedure.
3348 (scm_lreadr): use scm_get_hash_procedure instead of an argument
3349 for extended # processing.
3350 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
3351 scm_read_token): remove case_i, sharp arguments. Change callers.
3353 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
3355 * read.h (SCM_N_READ_OPTIONS): increase to 3.
3356 (SCM_CASE_INSENSITIVE_P): define.
3358 * read.c: add case-insensitive option to scm_read_opts.
3359 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
3360 to determine whether to convert symbol case.
3361 (default_case_i): definition removed.
3362 * read.c (scm_read_token): if case_i, downcase ic before doing
3365 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3367 * configure.in: Added configuration option `guile-debug'.
3368 Configure with --enable-guile-debug if you want a bunch of extra
3369 functions used for debugging when developing Guile.
3371 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3373 * procs.c (make-cclo): New undocumented debugging procedure: Make
3374 compiled closure with internal procedure PROC and length LENGTH.
3375 Only compiled if GUILE_DEBUG is defined.
3377 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3379 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3381 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3383 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3384 with 3 or more args internally to the evaluator.
3386 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3388 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3389 with 3 or more args internally to the evaluator. This is mainly
3390 because we don't want to pass entry and exit points of the
3391 debug support twice, but it also seems to increase the speed of
3392 the evaluator for such calls (e. g. (+ 1 2 3)).
3394 * backtrace.c (scm_display_application): New procedure:
3395 display-application; Set fancy printing parameters individually
3396 for different types of display (backtrace, error, application).
3397 (These should of course be customizable!)
3399 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3400 clear the CHECK-flags.
3402 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3404 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3406 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3408 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3409 from pairs with a GLOC in the car.
3411 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3412 otherwise `symbol-hash' will behave badly.
3413 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3414 we get segmentation fault!
3416 * symbols.c: Added #include "weaks.h". New functions:
3417 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3418 moved to an extraneous library when we split libguile.)
3420 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3422 * filesys.c (scm_stat): stat now takes fport arguments too as
3423 documented in the manual.
3425 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3427 * debug.c (scm_single_step): Bugfix: Call continuation with
3428 scm_call_continuation instead of throwing to it.
3430 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3432 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3433 argument wasn't declared to be optional.
3435 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3437 * stime.c (scm_init_stime): Add feature "current-time".
3439 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3441 * throw.h: prototype for scm_exit_status.
3442 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3443 args to derive an exit status. Allows (quit) to work from a
3445 (scm_exit_status): new function.
3448 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3450 * eval.c (scm_deval): Removed some old code.
3451 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3453 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3456 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3459 * procs.c: Introduce the existent C function scm_thunk_p at the
3460 Scheme level as well.
3462 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3464 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3465 used from C to easily lookup the value of a symbol in the current
3468 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3470 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3471 scm_init_unif in this file. This will also fix a previous problem
3474 * configure.in: Added AM_MAINTAINER_MODE
3476 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3478 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3481 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3483 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3484 source files that are not always included in libguile but should
3485 have their dependencies calculated by automake. This variable is
3486 recognized by automake, no further magic is needed.
3487 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3488 to deal exclusively with *.lo files, as it seems. The *.o files
3489 are built automatically when the corresponding *.lo file gets
3492 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3494 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3497 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3499 * unif.c (scm_array_set_x): minor change to argument error checking.
3501 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3503 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3504 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3505 They should only be included in the library at configure.in's
3507 (libguile_la_LDADD): Include the appropriate .lo files here.
3508 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3509 so we know when to build them (and their .lo bretheren).
3510 * configure.in (LIBLOBJS): New substituted variable. We let
3511 configure decide which .o files to include in LIBOBJS, and then
3512 put the corresponding list of .lo files in LIBLOBJS. The latter
3513 is what we pass to libtool.
3514 * Makefile.in, configure: regenerated.
3516 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3518 * symbols.c (scm_sysintern0): New function. Contains the core of
3519 old scm_sysintern but doesn't take a second value argument.
3520 (scm_sysintern): Now uses scm_sysintern0.
3521 (scm_sysintern_no_module_lookup): Renamed to
3522 scm_sysintern0_no_module_lookup and doesn't take a second value
3523 argument any longer.
3525 * symbols.h (scm_sysintern0: Added declaration.
3527 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3528 scm_sysintern when interning option keys. Otherwise we risk
3529 destroying the values of already interned variables.
3531 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3532 scheme-level boolean (use SCM_NFALSEP).
3534 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3536 (scm_backtrace): New function. (C version of old function from
3537 boot-9.scm) Motivation: Make it possible to display backtraces
3538 without depending on boot-9.scm. (I'm uncertain if this
3539 motivation is good enough...)
3541 * root.h (scm_root_state): Add member the_last_stack_var.
3542 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3544 * root.c (mark_root): Mark scm_the_last_stack_var.
3546 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3549 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3551 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3552 1. mark_lazy_catch didn't mark the smob.
3553 2. Both functions above have standard variants:
3554 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3555 free_lazy_catch --> scm_free0.
3557 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3559 * throw.c (scm_internal_lazy_catch): New function.
3560 (scm_lazy_catch): Rewritten to use it.
3561 (scm_ithrow): Handle the new lazy catch representation.
3562 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3563 that doesn't have a jmpbuf is a lazy catch clause.
3564 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3565 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3566 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3568 (scm_init_throw): Register the new lazy-catch smob type.
3569 * throw.h (scm_internal_lazy_catch): decl for new function.
3571 * throw.c (scm_internal_catch): Doc fixes.
3573 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3574 configure.in. Including this might cause problems if applications
3575 that link against libguile include their own copies of alloca, but
3576 if they're using autoconf, they should be adding libguile to LIBS
3577 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3578 the copy in libguile, and things will be okay. (I think.)
3580 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3582 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3584 strop.h: move prototypes too.
3586 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3588 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3591 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3592 etc. I deleted them from filesys.c long ago, but didn't
3593 notice they were here too (although ineffective since
3594 sys/stat.h wasn't included).
3596 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3598 * eval.c: Don't define alloca in GCC case. gcc will automatically
3599 use __builtin_alloca if appropriate.
3601 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3603 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3604 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3605 that values of automatic variables are preserved. See comments
3606 for safe_setjmp for details.
3608 Change from Thomas Morgan:
3609 * variable.c: Include eq.h.
3610 (var_equal): New function.
3611 (variable_smob): Use var_equal as the discriminator for variables.
3613 * throw.c (s_throw): Remove extraneous declaration.
3615 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3616 * eval.c: Add necessary CPP cruft to support that.
3617 * configure, Makefile.in, scmconfig.h.in: regenerated.
3619 Change from Thomas Morgan:
3620 * procprop.c (scm_procedure_properties): Convert the Scheme
3621 boolean returned by scm_procedure_p into a C boolean before using
3622 it as a condition for SCM_ASSERT.
3623 (scm_procedure_property): Likewise.
3625 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3626 indications of Unixness.
3629 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3631 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3633 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3635 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3636 "unknown # object" error messages.
3638 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3639 (scm_i_index) and declare it static. Add a 'direction' argument
3640 to indicate what way the search should go.
3641 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3643 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3644 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3646 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3648 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3650 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3651 to avoid clash with various scsh forks.
3653 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3655 The following two changes (ramap.c, throw.c) are motivated by the
3656 apparent unportability of forward declarations of static arrays of
3657 the form `static foo bar[];'.
3659 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3660 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3662 * throw.c (scm_throw): Moved above scm_ithrow.
3664 * options.h: Removed the extern declarations of scm_yes_sym and
3665 scm_no_sym since these are static.
3667 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3669 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3671 * Makefile.am: remove AWK=@AWK@.
3672 Add a rule for generating errnos.list.
3673 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3675 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3676 don't extract errnos, just set a variable (avoids the
3677 need to recompile error.c just because configure is run.)
3679 * unif.h: update prototypes.
3680 * unif.c (scm_uniform_array_read,write): change the offset and
3681 length arguments to start and end, for consistency.
3683 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3685 * ioext.h: update prototypes.
3686 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3687 scm_read_line_x, it's a more general procedure using an
3688 interface from scsh. read-line and read-line! are now defined
3690 Note that the new read-line trims the terminator
3691 by default, previously it was appended to the returned string. An
3692 optional argument specifies how to process the terminator (scsh
3693 compatible). For the old behaviour: (read-line port 'concat).
3694 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3695 returns a pair, but is converted to multiple values if the scsh
3698 socket.h: update prototypes.
3699 * socket.c (scm_recvfrom): for consistency with other procedures,
3700 take start and end as separate optional arguments.
3701 (scm_recv, scm_recvfrom): don't allow the second argument
3702 to be a size, only a buffer. Change the scheme names to
3703 recv! and recvfrom!. Don't return the buffer.
3705 * ioext.h, posix.h: move prototypes too.
3706 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3707 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3708 "read.h" and "unif.h".
3709 * ioext.c: include "chars.h"
3711 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3713 * dynl.c: The dynamic linking and module registration functions
3714 are now defined even when dynamic linking is not available for the
3715 host system. Some of their functionality can be done without
3716 dynamic linking; when it's really needed, they throw errors.
3718 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3720 * configure.in: Only define DYNAMIC_LINKING when one of the system
3721 dependent functions is detected.
3722 * dynl.c (scm_dynamic_func): New function to get the address of a
3723 function in a dynamic object.
3724 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3725 produced by scm_dynamic_func as the thing to call.
3727 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3729 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3730 (scm_register_module_xxx, scm_registered_modules,
3731 scm_clear_registered_modules): New functions.
3733 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3735 * symbols.c (scm_sysintern): Renamed to
3736 scm_sysintern_no_module_lookup.
3737 (scm_sysintern): New function to take the place of the old
3738 scm_sysintern. It uses the current toplevel lookup closure to give
3739 the symbol its value. This is a temporary hack to put packages
3740 like gtcltk into their own module.
3741 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3742 us whether `scm_top_level_lookup_closure_var' has been initialized
3744 * eval.c (scm_init_eval): Set it.
3746 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3748 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3749 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3751 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3753 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3754 scm_sys_dup): deleted: FD capability will be added to other
3756 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3757 scm_fd_free, fd_smob, scm_intern_fd.
3758 (scm_open): renamed from scm_sys_open. Return a port instead of
3759 an FD object. Make the mode argument optional.
3760 (scm_sys_create): deleted, it's just a special case of open.
3761 (scm_init_filesys): move interning of constants O_CREAT etc.,
3762 here (were previously using SCM_CONST_LONG macro).
3763 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3765 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3766 include "fports.h" and <stdio.h>
3767 (scm_stat, scm_select): don't support FD objects.
3769 * error.h: adjust scm_syserror_msg prototype.
3770 * error.c (scm_syserror_msg): take an extra argument for errno.
3771 Using the global value didn't always work, since it could be
3772 reset by procedure calls in the message or args arguments.
3774 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3775 I don't understand why the check was there (and what about the
3778 * strop.c (scm_string_copy): allow shared substrings to be copied.
3780 * unif.h: corresponding change to prototypes.
3781 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3782 recognize two new optional arguments: offset and length. Allow
3783 the port argument to be an integer (file descriptor, for scsh).
3784 Include <unistd.h> for "read" prototype.
3786 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3788 * socket.c: don't include filesys.h.
3790 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3792 * Makefile.am: add AWK=@AWK@ (?)
3794 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3796 Add a rule to generate errnos.c from errnos.
3797 * error.c (scm_init_error): include errnos.c.
3798 * errnos_cnvt.awk: new file, converts the list of errno codes to
3800 * errnos_get.c: new file.
3801 * errnos.default: new file, contains errnos to try if they can't
3802 be extracted from errno.h.
3803 * configure.in: if using GCC, try and extract errno codes from
3807 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3809 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3810 * Makefile.am: Made libguile into a libtool library.
3811 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3812 Set libtool_libs to indicate that libguile is a libtool library.
3813 See guile/ChangeLog for details.
3814 * .cvsignore: ignore "*.lo", the libtool library objects.
3816 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3818 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3819 use htons in getservbyport argument.
3821 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3823 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3824 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3827 * objprop.c (scm_object_property): No need to take the CDR of the
3828 value returned by scm_object_properties, since Aug 20 change.
3830 * configure.in: When checking for struct linger, #include
3831 <sys/types.h> as well as <sys/socket.h>. I've never known
3832 <sys/types.h> to cause any portability problems, and Solaris's
3833 <sys/socket.h> needs it.
3834 * configure: Rebuilt.
3836 I think the Sun compiler has chosen a perverse way to interpret
3837 ANSI declarations combined with K&R definitions. We'll
3838 appease it a little bit. But when it invades France, we fight.
3839 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3840 * print.h (scm_iprlist): Here too.
3841 * numbers.c (scm_divbigdig): Change definition to match
3842 declaration in numbers.h.
3843 * unif.c (scm_makflo): Change definition to match declaration in
3846 * init.c (scm_boot_guile): Don't return the value of
3847 scm_boot_guile_1. This function doesn't return a value;
3848 scm_boot_guile_1 doesn't return a value (or return at all).
3850 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3853 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3854 compile. I have a feeling this function is a bad idea anyway ---
3855 one should always test for features, not systems.
3857 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3858 semicolons. Only pure luck kept this from being noticed earlier.
3860 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3862 * socket.c (scm_recvfrom): Added missing semicolon.
3864 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3866 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3867 the buffer and start and end positions for scsh networking
3870 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3872 * configure.in: Revert previous change to this file; the problem
3873 is due to transient automake weirdness.
3874 * configure: Rebuilt.
3876 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3877 PLUGIN/guile.libs. configure generates the latter from the former.
3878 * Makefile.in: Rebuilt.
3880 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3881 need this if we install scripts, like guile-snarf.
3882 * configure: Rebuilt.
3884 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3886 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3888 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3890 * socket.c (scm_addr_vector): fix faulty scm_listify.
3892 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3894 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3895 style block comment is no longer considered an error.
3897 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3899 * PLUGIN/guile.libs.in: New file.
3900 * PLUGIN/guile.libs: Removed from repository.
3901 * configure.in: Create PLUGIN/guile.libs from
3902 PLUGIN/guile.libs.in. This is for including additonal libraries
3903 needed for dynamic linking.
3904 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3905 instead of PLUGIN/guile.libs.
3907 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3909 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3911 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3912 occurrences of the given element from the list, not just the
3913 first. This is how the Emacs Lisp functions behave, how the
3914 analogous Common Lisp functions behave, and (I believe) how the
3915 older Maclisp functions worked. I realize that this change may
3916 break code, but it seemed better to break it before the Guile
3919 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3920 Their prototypes were already present in gc.h, but they weren't
3922 (scm_init_storage): Initialize scm_protects.
3923 * root.c (scm_protects): New element of scm_sys_protects.
3925 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3927 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3929 * libguile.h: Added #include "libguile/net_db.h".
3931 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3932 30 change. That file is only meant for communication between the
3933 configuration process and load.c. If code linked against libguile
3934 wants to get at the paths mentioned in libpath.h, it can call
3935 functions declared in load.h.
3937 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3939 * libguile.h: Removed #include "libguile/fdsocket.h"
3941 * net_db.c: Added #include <sys/socket.h>.
3943 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3945 * filesys.c (scm_input_waiting_p): use select in preference to
3946 FIONREAD, since the latter doesn't detect EOF.
3947 Throw error if neither select nor FIONREAD available.
3949 * socket.c (scm_connect): take a port, not a fd object.
3950 (scm_fill_sockaddr): throw an error if fam is not recognised.
3951 (scm_bind): use scm_fill_sockaddr.
3952 (scm_listen): take a port, not a fd object.
3953 (scm_accept): take and return a port. return #f in the car if
3954 address can't be got
3955 (scm_sock_fd_to_port): new procedure.
3956 (scm_socket): use scm_sock_fd_to_port.
3957 (scm_addr_vector): throw error if unrecognised address type.
3958 take an extra argument with the calling procedure name.
3959 (scm_getsockname): take a port. return #f if address can't be got.
3960 (scm_getpeername): take a port. return #f if address can't be got.
3961 (scm_recvfrom): take a port. return #f for address component if can't
3963 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3964 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3966 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3968 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3969 use separate data pointers, to allow them to be designed
3970 independently and reused.
3971 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3972 Renamed from catch_body, catch_handler, and uncaught_throw; made
3974 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3976 (scm_catch): Use the above.
3977 (scm_throw): Don't bother printing a message for an uncaught
3978 throw; we establish a default handler in init.
3979 * throw.h (scm_internal_catch): Prototype updated.
3980 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3982 (struct scm_body_thunk_data): New structure, used as data
3983 argument to scm_body_thunk.
3984 * init.c (struct main_func_closure): New structure, packaging up
3985 the data to pass to the user's main function.
3986 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3987 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3988 scm_internal_catch to establish a catch-all handler, using
3989 scm_handle_by_message. This replaces the special-case code in
3991 (invoke_main_func): Body function for scm_internal_catch; invoke
3992 the user's main function, using the main_func_closure pointer to
3993 decide what to pass it.
3994 * root.c (struct cwdr_body_data): Remove handler_proc member.
3995 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3996 (cwdr_handler): Removed.
3998 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4000 * socket.h (SCM_P): update bind prototype.
4001 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
4002 include "feature.h".
4003 (scm_socket): return a port, not a file descriptor object.
4004 include "fports.h" and <unistd.h>
4005 (scm_bind): take a port, not a file descriptor object.
4006 take an extra argument for address args.
4008 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
4009 INADDR_NONE, INADDR_LOOPBACK.
4011 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4013 * init.c: include net_db.h and not fdsocket.h.
4014 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
4016 * Makefile.am: corresponding changes.
4017 * socket.h: renamed from fdsocket.h, fix names.
4018 * net_db.h: renamed from socket.h, fix names.
4019 * socket.c: renamed from fdsocket.c.
4020 remove _sys from procedure names.
4021 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
4022 add "socket" to features list.
4023 * net_db.c: renamed from socket.c.
4024 remove _sys from procedure names.
4025 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
4026 add "net-db" to features list.
4027 include "net_db.h". don't include <sys/socket.h> or
4030 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4032 * tags.h (scm_tags): Removed comma at end of last enumerator.
4034 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
4036 Don't use GCC extensions to allocate space for debugging frames.
4037 (Here he goes again! Why do we put up with this?!)
4038 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
4039 an scm_debug_info structure, not an in-line array of them. Add
4040 'info' member, to say how many vect elements we've used, for eval
4042 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
4043 a new variable debug_info_end to mark the end of vect, instead of
4044 the address of the 'info' pointer itself.
4045 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
4046 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
4047 (SCM_APPLY): Explicitly allocate space for debug.vect.
4048 * debug.c (scm_m_start_stack): Same, for vframe.vect.
4049 * stacks.c: Adjusted for new debug frame structure.
4050 (RELOC_INFO, RELOC_FRAME): New macros.
4051 (stack_depth, read_frames): Use them, and new scm_debug_frame
4052 element 'info', instead of magically knowing that eval frames have
4053 an info pointer sitting after vect.
4054 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
4056 (scm_init_stacks): Formatting tweaks.
4058 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
4060 Give GCC more control flow information, so it can be sure that
4061 variables aren't used uninitialized.
4062 * error.h (scm_error, scm_syserror, scm_syserror_msg,
4063 scm_sysmissing, scm_num_overflow, scm_out_of_range,
4064 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
4065 scm_misc_error): Tell GCC that these functions never return.
4066 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
4067 out the field type, call abort if SCM_ASSERT returns, to placate
4069 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
4070 scm_wta ever returns. We can't handle this case anyway, and this
4071 gives the optimizer more information.
4072 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
4073 scm_wta ever returns.
4075 In some cases, the code is fine, but GCC isn't smart enough to
4076 figure that out; this usually happens when one variable is only
4077 initialized and used when a particular condition holds true, and
4078 we know that condition will never change within a given invocation
4079 of the function. In this case, we simply initialize the variables
4080 to placate the compiler, hopefully to a value which will cause a
4081 crash if it is ever actually used.
4082 * print.c (scm_iprin1): Initialize mw_pos.
4083 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
4084 * throw.c (scm_ithrow): Initialize dynpair.
4085 * unif.c (scm_uniform_vector_ref): Initialize cra.
4086 * struct.c (init_struct): Initialize prot.
4087 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
4089 * strports.c (scm_eval_0str): Don't return uninitialized garbage
4090 if EXPR contains no expressions.
4092 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
4094 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
4095 cause an infinite loop (???). So much for the algebraic
4096 equivalency of variable-sized arrays and alloca...
4098 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
4100 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
4101 a SCM boolean, not a C boolean.
4103 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
4105 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
4106 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
4107 rules for raising scm_mtrigger. Previously, unfortunate but not
4108 unlikely circumstances could result in almost constant invokation
4109 of the gc. Now, this situations should be less likely, but they
4110 are not prevented completely.
4112 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
4114 * numbers.c (scm_fuck): Procedure removed; looks like old test
4116 * numbers.h: Prototype removed.
4118 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
4120 * debug.h (scm_debug_frame): Change `vect' member from an in-line
4121 array to a pointer, to match my Nov 21 change in eval.c.
4123 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4125 * libguile.h: Added #include "libguile/backtrace.h", #include
4126 "libguile/stacks.h".
4128 * strings.c (scm_string scm_make_string scm_string_ref
4129 scm_string_set_x scm_string_equal_p scm_string_append):
4130 Bugfix according to scm patch from Aubrey Jaffer:
4131 Corrected long-standing
4132 (not (eqv? (integer->char 128)
4133 (string-ref (make-string 1 (integer->char 128)) 0)))
4134 bug found by John Kozak <jk@noontide.demon.co.uk>.
4136 * strports.c, strports.h: Make scm_eval_0str return the value of
4137 the last expression evaluated (previously, it returned void).
4139 * strports.c, strports.h: New function: scm_read_0str. Does what
4142 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4144 * simpos.c (scm_getenv): return #f if string can't be found in the
4145 environment instead of throwing an exception, for compatibility
4146 with numerous other systems.
4148 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
4150 * Makefile.am (.c.x): Use guile-snarf.
4151 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
4153 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
4155 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4157 * backtrace.c (scm_display_error_message): Made non-static, and
4158 renamed from display_error_message.
4159 * backtrace.h (scm_display_error_message): Added extern decl.
4160 * throw.c (uncaught_throw): Use it to display the error message.
4162 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
4164 * inet_aton.c: Use #if 0, not #ifdef 0.
4166 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
4168 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
4169 to convert the returned value.
4170 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
4171 the offset argument.
4173 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4175 Add new interface to catch/throw, usable from C as well as
4177 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
4178 (scm_internal_catch): New function, replaces...
4179 (scm_catch_apply): Deleted.
4180 * throw.c (scm_catch_apply): Deleted; replaced with a more general
4181 mechanism which is a bit more code, but can be used nicely from C
4182 and implement the Scheme semantics as well.
4183 (scm_internal_catch): This is the replacement; it's named after
4184 the analogous function in Emacs.
4185 (scm_catch): Reimplemented in terms of the above.
4186 (struct catch_body_data, catch_body, catch_handler): New
4187 functions, used by scm_catch.
4188 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
4189 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
4190 support for new cwdr.
4192 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
4195 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
4197 * acconfig.h: Added DYNAMIC_LINKING symbol.
4198 * configure.in: Add option and checks for dynamic linking.
4199 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
4200 dynl.h: New files for dynamic linking support.
4201 * Makefile.am (libguile_a_SOURCES):
4203 (modinclude_HEADERS): Added "dynl.h".
4204 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
4206 * init.c (scm_boot_guile_1): Call
4207 scm_init_dynamic_linking to initialize dynamic linking support.
4209 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
4211 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
4212 (as we Schemers say). It needs to be global, so that I can tweak
4213 it for the proper operation of unexec.
4214 (scm_boot_guile_1_live): New variable, see above.
4216 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
4218 * guile-snarf.sh: Removed.
4219 * PLUGIN/guile.libs: Added dependency for -lm.
4220 * acinclude.m4: Renamed from aclocal.m4.
4221 * PLUGIN/greet: Removed.
4222 * Makefile.am, aclocal.m4: New files.
4223 * configure.in: Updated for Automake.
4225 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
4227 * eval.c (scm_definedp): Use top_level_lookup_closure_var
4228 and not top_level_lookup_thunk_var.
4230 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
4232 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
4234 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
4236 * eval.c (scm_definedp): Incompatibly changed to be a builtin
4237 Scheme function, instead of syntax. Single argument is now a
4240 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4242 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
4243 scm_ra_divide): Properly terminate statements passed as arguments
4244 to IVDEP macros. (Thanks to Bernard Urban.)
4246 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
4247 with non-constant sizes. (Thanks to Bernard Urban.)
4249 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4251 It's an "eval closure", not an "eval thunk." A thunk is a
4252 function of no arguments.
4253 * root.h (struct scm_root_state): Renamed
4254 top_level_lookup_closure_var from top_level_lookup_thunk_var.
4255 (scm_top_level_lookup_closure_var): Renamed from
4256 scm_top_level_lookup_thunk_var.
4257 * root.c (mark_root): Uses changed.
4258 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
4259 * init.c (scm_start_stack): Uses changed.
4260 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
4261 Change scheme-visible name to *top-level-lookup-closure* from
4262 *top-level-lookup-thunk*.
4264 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
4266 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
4267 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
4269 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
4271 * gc.c (struct scm_heap_seg_data): Doc fixes.
4273 * gc.c (scm_gc_sweep): Empty all segments' freelists before
4274 sweeping. Then, prepend each segment's free cells to its
4275 freelist, rather than wiping out the old value. (Thanks to Marius
4278 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
4279 scm_check_freelist, scm_debug_newcell): New functions and
4280 variables, for debugging freelist problems.
4281 * pairs.h (SCM_NEWCELL): New debugging version added.
4282 * gc.h (scm_debug_newcell): Added extern declaration, used by
4283 debugging version of SCM_NEWCELL.
4285 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4287 On some systems <libc.h> conflicts with <unistd.h>, and should not
4288 be #included at all.
4289 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
4290 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
4291 * configure.in: Call it.
4292 * posix.c, filesys.c: Use its results to decide whether or not to
4294 * configure, scmconfig.h.in: Rebuilt with autoconf and
4297 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4299 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
4300 pointer to the stdio stream before calling scm_setbuf0, so the
4301 latter will be able to retrieve it. I'm surprised this didn't
4302 segfault earlier. (Thanks to Christopher Lee.)
4304 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4306 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
4309 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4311 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
4312 number of stack narrowing specifier pairs. The first specifier in
4313 a pair controls inner border, the second the outer border. A
4314 number means cut that number of frames, a procedure object means
4315 cut until that object is found in operator position in a frame.
4317 * root.c (cwdr): Bugfix.
4319 * read.c: Recording of positions disabled by default.
4321 * procs.c (scm_closure_p): New function.
4323 * posix.c (scm_tmpnam): New function.
4325 * load.c: Added #include "throw.h".
4326 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
4329 * load.c, load.h (scm_read_and_eval_x): New function.
4331 * eval.c: Renamed debug option "deval" to "debug".
4333 (scm_eval_x): `eval!' is no longer accessible from the scheme
4334 level. Motivation: We can't allow operations which introduce
4335 glocs into the scheme level. Guile's type system can't handle
4336 these as data. Use `eval' or `read-and-eval!' as replacement.
4338 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
4339 SCM_CONSP since this is a macro!; Set vframe.prev to
4340 scm_last_debug_frame instead of 0. In this way we can look
4341 "above" the virtual start stack frame if we wish.
4342 (scm_debug_hang): New function: Useful for debugging Guile in
4343 certain tricky situations. Will probably be removed later...
4345 * debug.h: Changed semantics of debug option "backtrace". This
4346 option now only indicates whether we want automatic backtrace at
4349 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4351 * ports.c: #include "filesys.h"
4352 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
4354 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
4355 Motivation: This is system specific code which is related to file
4356 I/O. It also may use select. Added code by Gary Houston to
4357 detect presence of character in stdio buffers.
4359 * libguile.h: #include "libguile/libpath.h"
4361 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4362 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4363 SCM_SITE_DIR; Install libpath.h among the other include files.
4365 * load.c, load.h (scm_sys_package_data_dir): New function.
4367 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4369 * stacks.h: Bugfix: Don't use tail-array length field as stack
4370 length field! This screwed GC.
4372 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4374 * _scm.h: Added #ifndef around definition of macros min and max.
4376 * __scm.h: Added hooks for threads to plugin to in ints protection
4377 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4378 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4379 the main code in these macros duplicated and spread over multiple
4380 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4381 SCM_THREAD_SWITCHING_CODE.
4383 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4385 * snarf.h: New file.
4386 * guile-snarf.sh: New file.
4387 * Makefile.in (inner_h_files): Added snarf.h
4388 (ancillary, install, uninstall, distclean): Added actions for
4390 (.c.x): Use guile-snarf.
4391 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4392 (gen_c_files): Note that these depend on guile-snarf.
4393 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4394 now in "snarf.h". Added #include "snarf.h" to get them.
4395 * libguile.h: Added #include "snarf.h".
4396 (Patches applied and tweaked by Jim Blandy.)
4398 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4400 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4401 standards suggest against providing prototypes for system
4402 functions. Thanks to Greg Troxel.
4404 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4406 * strports.c (scm_eval_0str): New function.
4407 #include "read.h", to get prototype for scm_read.
4408 * Makefile.in (strports.o): Update dependencies.
4409 * strports.h: New prototype.
4411 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4412 scheme name from "int?" to "integer?". It seems to do the job.
4413 * numbers.h: Rename prototype too.
4414 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4417 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4418 scm_num_eq_p): Rename these according to R4RS conventions: call
4419 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4420 to making libguile R4RS compliant without ice-9...
4422 * load.c (scm_sys_search_load_path): Search for files under all
4423 extensions listed in the %load-extensions variable. If FILENAME
4424 is absolute, return it unchanged, without searching the load path.
4425 (scm_loc_load_extensions): New variable, pointing to
4426 %load-extensions' value cell.
4427 (scm_init_load): Initialize it, and the value it points to.
4428 (scm_primitive_load_path): Improve error reporting.
4430 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4431 of new Scheme variable %load-hook.
4432 (scm_primitive_load): Apply %load-hook to filename.
4434 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4436 * configure.in: add tests for figuring out whether buffered data
4437 is available in a FILE structure, which is needed by char-ready.
4439 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4442 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4443 exceptions using misc_error instead of syserror. It seems a bit
4444 odd to throw an exception if a string can't be found in the
4445 environment, but it's consistent with open-file, stat etc.
4446 (simpos.h): remove sys_ from getenv.
4448 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4449 occurs, throw an error instead of returning errno. Return value
4451 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4453 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4455 * filesys.c (scm_stat2scm): derive file type and permissions from
4456 the stat mode and append them to the returned vector.
4457 There isn't much overhead in doing this and it avoids the need to
4458 work with S_IRUSR et al. in Scheme.
4459 Define symbols scm_sym_regular etc.
4460 (scm_init_filesys): don't intern S_IRUSR etc.
4462 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4463 and s_primitive_load_path.
4465 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4467 * error.h: don't declare error symbols. prototype for scm_misc_error.
4469 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4472 * error.c: use SCM_SYMBOL to set up error keys.
4473 scm_misc_error: new procedure.
4475 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4477 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4478 between `#!' and `!#' is ignored.
4479 (skip_scsh_block_comment): New function.
4481 * feature.c (scm_set_program_arguments): New argument, FIRST.
4482 * feature.h: Update prototype.
4483 * init.c (scm_boot_guile_1): Pass new argument to
4484 scm_set_program_arguments.
4486 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4488 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4489 (scm_boot_guile): Call scm_set_program_arguments here, later than
4490 the old initialization.
4492 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4493 initialization procedure.
4494 - Delete in, out, err arguments; there are other perfectly good
4495 ways to override these when desired.
4496 - Delete result argument; this function shouldn't ever return.
4497 - Rename init_func argument to main_func, for less confusion.
4498 - Delete boot_cmd argument; main_func is more general.
4499 -Add 'closure' argument, to help people pass data to main_func
4500 without resorting to global variables.
4501 - Abort if reentered; don't bother returning an error code.
4502 - Call scm_init_standard_ports to set up the default/current
4503 standard ports; no need to pass them to scm_start_stack.
4504 - Remove code to evaluate the boot_cmd, and start the repl; let
4505 the user do something like that in main_func if they want.
4506 - Remove code to package up a return value; main_func can do any
4508 - Call exit (0), instead of returning.
4509 (scm_start_stack): Don't initialize the I/O ports here; that's
4510 weird. Delete in, out, err arguments. Move guts to
4511 scm_init_standard_ports, scm_stdio_to_port.
4512 (scm_init_standard_ports): New function, to set up current and
4513 default standard ports.
4514 (scm_start_stack, scm_restart_stack): Make these static.
4515 * init.h (scm_boot_guile): Adjust declaration.
4516 (scm_start_stack, scm_restart_stack): Remove externally
4517 visible declarations for these.
4518 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4520 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4521 written out several times in scm_start_stack.
4522 * fports.h: New declaration for the above.
4524 * feature.c (scm_set_program_arguments): New function.
4525 * feature.h: New declaration for the above.
4527 * ports.c: Formatting tweak.
4529 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4531 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4532 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4533 for obtaining the address of a car or cdr field. Motivation:
4534 &SCM_CXR make assumptions about the internal structure of the
4537 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4538 Motivation: see SCM_CXRLOC.
4540 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4541 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4542 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4543 Motivation: Safer use. Some other macros are defined in terms of
4544 these operations. If these are defined using the SCM_SETCXR
4545 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4546 to inefficiency and an <e1> with side-effects could potentially
4547 break. Also, these particular operations are heavily utilized in
4548 the garbage collector. In unoptimized code there will be a
4551 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4552 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4553 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4554 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4555 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4556 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4557 vports.c: Cleaned up use of pairs: Don't make any special
4558 assumptions about the internal structure of selectors and
4559 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4560 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4561 (Among other things, this change makes it easier to build Guile
4562 with certain compilers which have problems with casted lvalues.)
4564 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4566 * stacks.c: Improve selection of relevant stack frames when making
4567 a stack object. Introduce one level of indirection in the stack
4568 object to make it possible to "narrow" to a certain region of the
4569 stack. This facilitates making use of more clever algorithms (not
4570 implemented) for selecting relevant frames and gives a cleaner
4571 design since selection of frames can be done independently of
4572 extraction of frames from the real stack.
4573 (scm_stack_id): Also take #t as argument which means look at
4576 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4577 Turn n_tail into an integer directly representing current number
4578 of frames in stack. Add field tail.
4580 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4582 * debug.c (scm_make_memoized): Made it available at scheme level.
4583 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4584 SCM_NIMP before applying heavier predicates in argument checking.
4585 (scm_local_eval): Also take memoized object as argument.
4587 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4588 aren't created with zero length, but should such a strange
4589 creature suddenly turn up...
4591 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4593 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4594 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4596 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4598 * variable.c (scm_make_variable): Make the name hint optional, as
4600 (anonymous_variable_sym): Renamed from variable_sym. All uses
4603 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4604 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4605 of scm_primitive_load_path was also changed to
4606 "primitive-load-path", from "%try-load-path". Callers changed.
4607 We'd like to respect the convention that a function named
4608 "try-mumble" should behave just like the function called "mumble",
4609 but return #f instead of signalling some error.
4610 * load.h: Rename prototypes.
4612 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4614 * print.c (make_print_state, grow_print_state), print.h: Modified
4615 the print state representation: Don't use a tail array for
4616 recording of circular references. Resizing of the print state
4617 structure invalidates the print state pointer. To avoid passing
4618 around an indirect print state reference to all printing
4619 functions, we instead let the print state reference a resizable
4622 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4624 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4625 Don't crash when passed an improper list terminated by a
4626 non-immediate value.
4628 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4630 Allocate data for structures on an eight-byte boundary, as
4631 required by the tagging system.
4632 * struct.c (alloc_struct): New function.
4633 (scm_make_struct, scm_make_vtable_vtable): Call it.
4634 * struct.h (scm_struct_n_extra_words): Bump to 3.
4635 (scm_struct_i_ptr): New "field".
4636 * gc.c (scm_gc_sweep): When we need to free the data, use the
4637 information stored by alloc_struct to find the beginning of the
4638 block allocated to the structure, so we can free it.
4640 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4642 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4645 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4646 (scm_debug_info): New member: id.
4648 * stacks.c: Stacks are now represented as structs; Stacks have an
4649 id given to them by `start-stack'.
4650 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4652 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4653 Changed stack representation.
4655 * debug.c (scm_procedure_name): Try procedure property `name' for
4656 compiled closures aswell.
4658 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4660 * eval.c: scm_i_name moved to gsubr.c
4661 (scm_m_define): Record names of all kinds of procedure
4662 objects. (Earlier, only closures were recorded.)
4664 * procprop.h: Added declaration of scm_i_name.
4666 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4667 (scm_make_gsubr): Record names of compiled closures.
4669 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4671 * debug.c, debug.h: Removed obsolete code.
4673 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4674 stacks.c: Renamed regs --> scm_contregs.
4676 * print.c (scm_free_print_state): Cleanup print state before
4677 returning it to pool. It is better to do it here than in
4678 scm_prin1 since scm_prin1 is called often.
4680 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4681 s_set_source_property_x): Check that first argument is a pair or a
4684 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4685 scm_i_line, scm_i_column and scm_i_breakpoint global.
4687 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4688 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4691 * debug.h: Added debug object smob declaration and macro
4694 * configure.in: Build with backtrace.o and stacks.o if debug
4697 * Makefile.in: Added entries for new files: backtrace.c,
4698 backtrace.h, stacks.c and stacks.h.
4700 * symbols.c (scm_sym2ovcell): Fixed documentation.
4702 * _scm.h (min, max): Added.
4704 * async.c: Moved `min' macro to _scm.h.
4706 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4707 SCM_BACKTRACE_INDENT.
4709 * eval.c: Added new debug options `maxdepth' and `indent'.
4711 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4713 * print.h: Added selector SCM_PRINT_STATE.
4715 * print.c: New functions: scm_make_print_state,
4716 scm_free_print_state.
4718 * print.h: Added declarations for scm_make_print_state,
4719 scm_free_print_state.
4721 * debug.c (scm_m_start_stack): New acro.
4723 * debug.h: Small cleanup.
4725 * init.c (scm_boot_guile_1): Moved scm_init_debug below
4728 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

4753 More prototype-related changes from Marius Vollmer:
4754 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4755 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4756 * ports.h (ptobfuns): Added prototypes. This means some casting in
4758 * fports.c: Added casts for initializations, since the functions
4759 are defined to take FILE * as their stream argument, not SCM.
4760 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4761 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4762 to `char *str_data' to conform to prototype.
4764 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4766 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4768 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4770 * stime.c, stime.h: use SCM_P method.
4772 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4774 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4775 be given at least two arguments. Insist that lst's last element
4776 be a list, but don't make any requirements of its predecessors.
4778 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4780 * eval.c (scm_nconc2last): Revert last change; there seems to be
4781 other stuff going on here.
4783 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4785 * eval.c (scm_nconc2last): Make sure that each element of lst
4786 (which is a list of argument lists, except for the tail) is a
4787 proper list, i.e., finite and terminated by '().
4789 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4791 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4794 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4795 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4798 * vectors.c (scm_make_vector): Fill vectors with the undefined
4799 value, to help make Guile Scheme code more portable to other
4802 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4803 * symbols.h, tags.h: Doc fixes.
4805 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4807 * async.c (scm_take_signal): Doc fixes.
4809 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4811 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4812 want to subtract it from the modulus; we just want to leave it
4815 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4817 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4820 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4822 * throw.c (scm_catch_apply): Finished implementation of
4825 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4827 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4829 (scm_init_filesys): set "i/o-extensions" feature.
4832 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4834 * Makefile.in (root.o): Correct dependencies.
4836 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4838 * Makefile.in: Added dependency entry for root.o.
4840 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4841 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4843 * init.c (scm_start_stack): Set initial root continuation number
4846 * procs.c: New function: scm_thunk_p.
4848 * procs.h: Added declarations of scm_thunk_p.
4850 * root.c: Renamed `call-with-new-root' -->
4851 `call-with-dynamic-root'.
4852 (cwdr): Removed allocation of new root state. This should be done
4853 separately by use of scm_make_root.
4854 (scm_apply_with_dynamic_root): New function: Does what it
4855 sounds like. Needed when spawning threads.
4857 * root.h: Added member last_debug_frame to root state.
4858 Added #include "libguile/debug.h"
4860 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4861 arguments. The motivation is that code in root.c needs catch
4862 functionality, and we want to avoid code duplication.
4863 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4864 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4865 handlers that run without popping the stack into the dynwind
4868 * throw.h: Added prototypes for scm_catch_apply and
4871 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4873 * root.h (scm_root, scm_set_root): Decouple thread support details
4874 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4875 SCM_SET_THREAD_LOCAL_DATA.
4877 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4878 and tortoise scanning loop.
4880 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4882 * Makefile.in: Rebuild dependencies.
4884 * libguile.h: #include "libguile/print.h" before "smob.h", since
4885 the latter uses the print_state structure.
4887 * throw.c (scm_ithrow): Use the correct variable when checking to
4888 see if a given element of scm_dynwinds is a valid catch.
4890 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4891 structure, abort; don't just silently ignore the garbage.
4893 * _scm.h: #include "print.h" here, since it seems to be used just
4895 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4896 strports.c, unif.h: Don't #include "print.h".
4898 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4900 * feature.h (scm_loc_features): Removed external declaration.
4901 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4903 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4905 * feature.c (scm_init_feature): Added threads feature (needs to be
4906 initialized here, since features doesn't exist when
4907 scm_init_threads is called).
4909 * libguile.h: Added #include "libguile/../threads/threads.h".
4910 (This is a kludge to get thread support working. This should be
4913 * configure.in, acconfig.h: Added flags for thread support.
4915 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4918 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4919 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4922 * _scm.h: Added conditional #include "threads.h"
4924 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4925 SCM_THREADS_SWITCHING_CODE.
4927 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4928 allocate the basic dynamic root object.
4929 (scm_boot_guile): Added call to scm_init_root.
4931 * root.c, root.h: Added root smob.
4932 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4933 functions: Implements dynamic roots mostly according to spec in
4934 SCM manual. Main difference is that the second argument is a
4935 throw handler rather than an error "thunk".
4937 * root.h: Added declaration of scm_init_root.
4939 * root.c: Added #include "genio.h", #include "smob.h", #include
4940 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4942 (scm_init_root): Added #include "root.x".
4944 * throw.c: Added #include "stackchk.h"
4945 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4946 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4947 can be used in scm_call_with_new_root; Added reenabling of stack
4948 checking when catching a throw.
4950 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4952 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4954 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4955 element is not found, as per R4RS.
4957 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4959 * list.c: Doc fixes throughout.
4961 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4963 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4964 declare the char * to be const. Avoids a warning in rgx.c.
4966 * ports.h: spelling fix.
4968 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4971 * load.c (scm_sys_try_load_path): throw an error if file not found
4972 (like it says it in NEWS).
4974 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4976 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4977 PROPS slot to '(), not #f; it's an empty alist.
4979 * throw.h, throw.c: Use SCM_P instead of #if hair.
4981 Remove special support for uncaught throws; see throw.c for
4983 * throw.c (uncaught_throw): New function.
4984 (scm_ithrow): Call uncaught_throw if we don't find a throw
4985 target; don't mess with scm_bad_throw_vcell.
4986 (scm_bad_throw_vcell): Variable deleted.
4987 (scm_init_throw): Don't initialize it.
4989 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4992 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4994 * numbers.c (scm_istr2int): If the number is short (as most
4995 numbers are), just call scm_small_istr2int to deal with it.
4996 (scm_small_istr2int): New function, created by un-#ifdefing the
4997 non-bignum version of scm_istr2int and renaming it.
4999 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
5001 * load.c (scm_sys_try_load): don't check whether value returned
5002 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
5003 Change the Scheme name from %try-load to primitive-load.
5005 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
5006 Can avoid passing a message, allowing it to be derived in the
5007 error handler (e.g., if we want to throw to the key both from
5010 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
5012 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
5013 references now have a new appearance which is more compact and
5014 also gives a clue about what the target of the reference is.
5015 By setting parameters in the print state, more fancy printing can
5016 be achieved. This is used by the (not yet commited) backtrace
5019 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
5021 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
5024 * print.c: Added #include "struct.h". Removed function
5027 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
5028 scm_iprin1. Removed prototype for scm_prlist.
5030 * arbiters.c (prinarb),
5031 async.c (print_async),
5032 debug.c (prindebugobj, prinmemoized),
5033 eval.c (prinprom, prinmacro),
5034 filesys.c (scm_fd_print, scm_dir_print),
5036 mallocs.c (prinmalloc),
5037 numbers.c, numbers.h (scm_floprint, scm_bigprint),
5038 smob.h (scm_smobfuns),
5039 srcprop.c (prinsrcprops),
5041 unif.c, unif.h (scm_raprin1, rapr1),
5042 variable.c (prin_var): Changed argument `int writing' to
5043 `scm_print_state *pstate'.
5045 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
5046 that it will be called before scm_init_print.
5048 * print.c (scm_prin1): Print states are now allocated when calling
5049 scm_prin1 and then passed around to all printing functions as an
5050 argument. A cache `print_state_pool' enables reuse of print
5052 (scm_make_print_state): New function.
5053 (scm_iprin1): Adaption to print states.
5054 (scm_iprlist): An initial "hare and tortoise" scan brings down
5055 time complexity to O (depth * N). (Better time complexity will be
5056 achieved when the printing code is completely rewritten.)
5058 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
5060 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
5061 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
5062 it gets done whether or not the cache variable has a value.
5064 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5066 Distinguish #f and ().
5067 * __scm.h: #undef SICP.
5068 * pairs.h (SCM_EOL): Delete this definition, equating it with
5070 * tags.h (SCM_EOL): Give it a new definition here; I think I found
5071 the value it used to have. Doc fixes, too.
5073 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
5075 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
5076 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
5077 Lord's implementation of structs, allowing for tail arrays as
5078 described in the manual. Also fixed some bugs. (Both the interface
5079 and the implementation should be improved.)
5081 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
5083 * print.c, print.h: Closures now print like #<procedure foo (x)>.
5084 People who whish to see the source can do `(print-enable 'source)'.
5085 Removed #ifdef DEBUG_EXTENSIONS.
5087 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5089 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
5090 integer (assuming for now accepting an integer is a good thing).
5092 * error.c, fports.c: replace use of %S in lgh_error args with %s.
5093 %S will be used instead for write'ing arguments.
5095 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
5096 asserts. fix a few other asserts.
5097 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
5098 scm_uniform_vector_ref, scm_array_set_x,
5099 scm_dimensions_to_unform_array): change args in
5100 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
5101 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
5102 scm_substring_fill_x): likewise.
5103 gsubr.c (scm_gsubr_apply): likewise.
5104 eval.c (SCM_APPLY): likewise.
5106 * eval.c (4 places): replace scm_everr with lgh_error or
5109 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
5110 scm_memory_error): new procedures.
5111 scm_everr: deleted. can use scm_wta, dropping first two args.
5112 scm_error: convert NULL subr to SCM_BOOL_F.
5114 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
5117 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
5120 * error.c, error.h: new error keys: scm_arg_type_key,
5121 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
5123 scm_wta: reimplement using lgh_error instead of scm_everr.
5125 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
5127 * gdbint.c: scm_lread now has one more argument.
5129 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
5130 scm_port_\1; Added mutator scm_set_port_filename_x (used when
5131 loading source from non-file ports, which, e. g., happens when
5132 using the Emacs interface).
5134 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
5137 * read.c: Added code for recording of positions of source code
5138 expressions; New functions: recsexpr, scm_lreadrecparen;
5139 _scm_make_srcprops --> scm_make_srcprops
5140 (scm_flush_ws): Removed updating of positions counters. This work
5141 is already done by scm_gen_getc
5143 * read.h: Added prototype for scm_lreadrecparen
5145 * print.c: Added #include "alist.h"
5147 * eval.c: Added #include "hash.h"
5149 * eq.c: Added #include "ramap.h"
5151 * options.c: Documentation fixes.
5153 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
5154 (scm_init_srcprop): Adjusted size of initial source-whash. Name
5155 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
5156 --> scm_make_srcprops
5158 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
5159 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
5160 function calls in the definition of the whash access macros.
5162 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
5164 * init.c (scm_boot_guile): Add level of indirection to
5165 scm_boot_guile_1() to ensure that stack base pointer is properly
5166 initialized. There was no guarantee that variable i was the
5167 highest/lowest variable on stack (i.e. the call frame of
5168 scm_boot_guile was not completely protected from gc).
5170 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
5172 * ports.h (scm_port_table): put back file_name, it will be used to
5173 support debugging. Undo related changes in fports.c, ioext.c,
5176 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5178 * ports.h (scm_port_table): remove file_name member for now, it seems
5180 * fports.c (scm_open_file): don't set file_name in PTAB.
5181 (prinfport): don't use file_name in PTAB.
5182 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
5183 * ports.c (scm_add_to_port_table): don't intialize file_name.
5184 (scm_port_file_name): remove for now.
5185 * gc.c (scm_gc_mark): don't mark PTAB file_name.
5187 * fports.h (scm_mkfile): prototype deleted.
5188 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
5190 * debug.c, unif.c: use scm_out_of_range instead of
5191 wta for range errors (ASSERT still needs work).
5193 * error.c, error.h (scm_out_of_range): new procedure.
5195 * error.c, error.h (scm_out_of_range_key): new key.
5197 * posix.c (scm_sync): #else was missing.
5199 * error.c, error.h: append _key to names scm_num_overflow and
5202 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
5203 of consing an empty list.
5204 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
5205 of macros, saves code and string space.
5206 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
5207 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
5208 lower case. Rename scm_syserror_m to scm_syserror_msg.
5209 error.h: prototypes for new procedures.
5211 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
5213 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
5215 * error.c, error.h: setup scm_num_overflow key.
5217 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
5218 Remove definition of SCM_OVSCM_FLOW.
5220 * fports.c (scm_open_file): use SCM_SYSERROR_M.
5222 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
5223 explicit message and args.
5225 * error.c, error.h, __scm.h: change system_error_sym to
5228 * error.c (system_error_sym): remove leading %% from the Scheme name
5231 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
5233 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5235 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
5236 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
5237 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
5238 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
5239 renamed. (These were introduced by unsupervised name
5242 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5244 * print.c: Added code for detection of circular references during
5245 printing. (init_ref_stack, grow_ref_stack): New functions. Added
5246 a hook for printing of closures (accessible via print options).
5247 This leads to a split of calls to scm_iprin1 into two classes:
5248 elementary print operations (e. g. the code which prints a smob)
5249 still use scm_iprin1 while top level calls (like scm_display) use
5250 scm_prin1. scm_prin1 begins by clearing the data structure used
5251 to record reference information.
5253 * print.h: Added declarations of scm_prin1 and scm_prlist.
5255 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
5257 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
5259 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
5261 * error.c (err_head): scm_iprin1 --> scm_prin1
5263 * debug.c: Adjusted header comment.
5267 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
5269 * strerror.c: Doc fix.
5271 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5273 * gdbint.c (gdb_read): Now possible to run during GC.
5274 (unmark_port, remark_port): New functions.
5276 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
5278 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
5279 of allocating a new string object. Also, increase size by
5280 the factor 2 instead of 1.5.
5282 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
5284 * __scm.h (SCM_P): Corrected to run under traditional C.
5286 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
5289 * async.c: Calls to scm_sysintern corrected.
5291 * async.h (scm_async_clock): Redundant declaration removed.
5293 * continuations.c (scm_dynthrow): Redundant declaration removed.
5295 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
5296 Definition typos corrected.
5298 * debug.h: Missing declarations of functions in debug.c added
5301 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
5302 Missing declarations to functions in eval.c added.
5304 * filesys.c: Possibly uninitialized variable rv.
5306 * gc.h (scm_object_addr, scm_unhash_name): Missing
5307 declarations of functions defined in gc.c added.
5309 * genio.c: Possible typos str_data -> wstr_data. ???
5311 * genio.c: Possibly unintended shadowing of local variable
5312 `int c' (gotos out of scope of inner `c'). ???
5314 * init.c: Uninitialized `SCM last' may be used.
5316 * ioext.h: (scm_sys_isatty_p): Typo.
5318 * list.h (scm_list_head): Missing prototype for function in
5321 * numbers.c (scm_two_doubles): Changed from extern to static
5322 (is used only within numbers.c).
5324 * numbers.h: Repeated declarations removed.
5326 * ports.h (scm_close_all_ports_except): Declaration for the
5327 function defined in ports.c added.
5329 * posix.h: Missing declarations added.
5331 * procs.h (scm_make_subr_opt): Missing declaration added.
5333 * socket.h (scm_sys_gethost): Missing declaration added.
5335 * socket.h: Redundant declarations removed (they are in fdsocket.h).
5337 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
5338 Missing declarations added.
5340 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
5342 * struct.c: Uninitialized variable `SCM answer' may be used.
5344 * unif.c (l2ra): Declaration prototype.
5346 * unif.c (scm_array_equal_p): Dummy definition removed (it is
5347 defined in ramap.c).
5349 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
5350 Redundant declarations removed (they are in ramap.h).
5352 * variable.h (scm_make_udvariable,
5353 scm_make_undefined_variable): Declaration corrected to
5354 correspond variable.c.
5356 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
5357 Missing declarations added.
5359 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5361 * Makefile.in (distclean): Don't forget to delete fd.h.
5363 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5365 * fd.h.in, tags.h: Trivial cleanups.
5367 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5368 marksweep.h just declared functions from gc.c.
5369 * gc.h, libguile.h: Don't #include "marksweep.h".
5370 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5371 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5372 dependencies updated.
5374 * libguile.h: Don't #include "files.h"; it's been deleted.
5376 * files.c (scm_sys_delete_file): Moved to filesys.c.
5377 File is now empty; deleted.
5379 * filesys.c: scm_sys_delete_file is now here. Remove
5380 #if's; they seem to rely on remnants of an old portability
5381 regimen. If the problems come up again, solve them properly,
5382 using autoconf. Specifically: Don't test M_SYSV, and #define
5383 remove to be unlink if it's #defined; don't use remove just
5384 because HAVE_STDC_HEADERS is #defined.
5385 * filesys.h: Add declarations for scm_sys_delete_file.
5386 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5387 files.o, files.h, files.c, and files.x.
5388 * init.c: Don't #include "files.h", and don't call scm_init_files.
5390 Use SCM_P instead of PROTO; the latter intrudes on the user's
5392 * params.h: Deleted; definition of SCM_P moved to...
5393 * __scm.h: ... here, where it replaces PROTO macro.
5394 * libguile.h, smob.h: Don't #include "params.h".
5395 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5396 smob.h: Fix prototypes accordingly.
5397 * Makefile.in: Update dependencies.
5398 (inner_h_files): Remove params.h.
5400 * gc.c: #include "gc.h"; every module should include its header,
5401 to let the compiler cross-check the declarations against the
5404 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5405 simpos.h: #include "libguile/__scm.h".
5407 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5409 * init.c: Don't forget to #include smob.h and init.h.
5410 * Makefile.in: Dependencies updated.
5412 * smob.h: Use PROTO instead of #if __STDC__.
5414 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5416 * __scm.h: Doc fixes.
5418 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5419 <angles>; this allows `make depends' to work properly.
5421 * libguile.h: #include smob.h and pairs.h before the others; they
5422 define typedefs used by other headers.
5424 C files should #include only the header files they need, not
5425 libguile.h (which #includes all the header files); the pointless
5426 recompilation was wasting my time.
5427 * Makefile.in (all .o dependency lists): Regenerated.
5428 * libguile.h: Don't try to get a definition for size_t here...
5429 * __scm.h: Do it here.
5430 * _scm.h: Since this is the internal libguile header, put things
5431 here that all (or a majority) of the libguile files will want.
5432 Don't #include <libguile.h> here; that generates dependencies on
5433 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5434 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5435 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5471 "unif.h", "throw.h", "tag.h", "symbols.h", "struct.h",

5531 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
5532 * weaks.c: Get "weaks.h".
5534 * stackchk.h: #include "libguile/debug.h",
5536 * print.h, read.h: #include "options.h", since everyone who uses
5537 either of these files will need that.
5539 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5540 anyone who uses this file will need them to define the smob
5541 printing functions. Also, get markers.h, since people will need
5542 to #define the mark functions.
5544 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5545 * ports.h: ... to here.
5547 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5548 don't rely on archaic C default type rules.
5550 * fports.h: #include "libguile/ports.h", since you need that in
5551 order to parse this.
5553 * genio.h: #include "libguile/print.h", because you need that to
5554 parse this; don't bother #including "ports.h", since print.h gets
5557 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5559 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5560 this; it's now a reference to an element of *scm_root.
5562 * debug.h: Don't #include "options.h"; the compiler won't be able
5563 to find that once the headers are installed; instead, #include
5564 "libguile/options.h".
5565 * gc.h: Same, with marksweep.h.
5566 * mbstrings.h: Same, with symbols.h.
5567 * scmhob.h: Same, with _scm.h.
5568 * smob.h: Same, with params.h.
5570 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5571 C files; there's no need for this, and it forces recompilations
5574 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5576 * error.c (scm_error): declare scm_error_callback.
5578 * error.h: prototype for scm_error_callback.
5580 * __scm.h: define lgh_error.
5581 (SCM_SYSERROR): redefine using lgh_error.
5583 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5585 * error.c (scm_error): new procedure.
5587 * error.h: prototype for scm_error.
5589 * Makefile.in (install): install scmconfig.h from the current
5590 directory, not $(srcdir).
5592 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5594 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5595 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5596 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
5597 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
5598 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,

5601 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5602 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5603 vports.h, weaks.h: #include "libguile/__scm.h", not
5604 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5605 dependencies are within libguile properly.
5607 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5609 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5610 when scmconfig.h doesn't exist.
5612 * load.c (scm_sys_try_load): Correct spelling.
5614 * feature.c (scm_loc_features): Make this static.
5616 * Makefile.in (libpath.h): Omit trailing slash from path. We
5617 shouldn't require it of users, so why put it here?
5619 Move code to initialize and search %load-path from ice-9 to C
5620 code, so we can use the load-path to find the ice-9 boot code;
5621 this makes it easier to run Guile without installing it. See
5622 corresponding changes in guile/Makefile.in.
5623 * feature.c: Move stuff concerned with the load path to load.c.
5624 (scm_compiled_library_path): Deleted.
5625 Don't #include libpath.h here.
5626 * feature.h: Don't mention scm_compiled_library_path.
5627 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5628 <sys/stat.h>, and <unistd.h> (if present).
5629 (R_OK): #define if the system hasn't deigned to.
5630 (scm_loc_load_path): New variable.
5631 (scm_init_load_path, scm_sys_search_load_path,
5632 scm_sys_try_load_path): New functions.
5633 (scm_init_load): Initialize scm_loc_load_path to point to the
5634 value cell of the Scheme %load-path variable.
5635 * load.h: Add declarations for scm_sys_search_load_path,
5636 scm_sys_try_load_path.
5637 * init.c: Call scm_init_load_path.
5638 * Makefile.in (feature.o, load.o): Dependencies updated.
5640 * load.c, load.h: Rewrite using PROTO macro.
5642 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5644 * gc.c (scm_cellp): New function: C predicate to determine if an
5645 SCM value can be regarded as a pointer to a cell on the heap.
5647 * gc.h: Added declaration of scm_cellp.
5649 * gdb_interface.h: New file: The GDB interface header from the GDB
5652 * gdbint.c: New file: GDB interface.
5654 * gdbint.h: New file: GDB interface.
5656 * libguile.h: Added #include <libguile/gdbint.h>.
5658 * init.c (scm_boot_guile): Added scm_init_gdbint.
5660 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5661 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5662 found if object files and source are kept separate).
5664 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5666 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5668 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5670 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5671 TK_SRC_DIR; they're not relevant any more.
5673 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5674 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5676 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5678 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5679 search path, so we can find the <libguile/MUMBLE.h> headers.
5681 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5683 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5684 implicit in the .c.o rule.
5685 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5688 Put the library path in a header file, instead of passing it on
5689 the command line in every compilation.
5690 * Makefile.in (libpath.h): New target.
5691 (feature.o): Depend on libpath.h.
5692 (clean): Delete libpath.h.
5693 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5694 * feature.c: ... #include "libpath.h" here.
5695 * .cvsignore: Ignore libpath.h.
5697 Don't install the unwashed masses of Guile header files in the
5698 main #include path; put most of them in a subdirectory called
5699 'libguile'. This avoids naming conflicts between Guile header
5700 files and system header files (of which there were a few).
5701 * Makefile.in (pkgincludedir): Deleted.
5702 (innerincludedir): New variable; this and $(includedir) are enough.
5703 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5704 (installed_h_files): Divide this up. Now this variable lists
5705 those header files which should go into $(includedir) (i.e. appear
5706 directly in the #include path), and ...
5707 (inner_h_files): ... this new variable says which files appear in
5708 a subdirectory, and are referred to as <libguile/mumble.h>.
5709 (h_files): List them both.
5710 (install): Create innerincludedir, not pkgincludedir. Put
5711 the installed_h_files and inner_h_files in their proper places.
5712 (uninstall): Corresponding changes.
5713 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5714 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5715 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5716 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5717 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5718 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5719 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5720 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5721 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5722 vports.h, weaks.h: Find __scm.h in its new location.
5723 * __scm.h: Find scmconfig.h and tags.h in their new locations
5724 (they're both "inner" files).
5726 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5728 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5730 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5732 * posix.c: Doc fixes.
5734 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5736 * socket.c: Don't include a prototype for inet_aton; just use a
5737 K&R style declaration, to avoid warnings but minimize the chance
5738 of conflicts with the system.
5740 On NextStep, <utime.h> doesn't define struct utime, unless we
5741 #define _POSIX_SOURCE before #including it.
5742 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5743 * acconfig.h: New comment text for above CPP symbol.
5744 * configure.in: Call it.
5745 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5747 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5749 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5750 testing for __EMX__.
5752 * posix.c: #include <libc.h>, if it exists.
5754 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5755 don't even know if the latter exists.
5757 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5758 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5759 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5761 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5763 (scm_init_posix): Use them when initializing the Scheme constants
5766 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5768 * Makefile.in (libdir, includedir, bindir): Use the
5769 autoconf-supplied values, instead of deriving them ourselves.
5770 (pkgincludedir, datadir, pkgdatadir): New variables.
5771 (install, uninstall): Put the header files in a special
5772 subdirectory, not in the main search path.
5774 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5775 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5777 * Makefile.in (IMPLPATH): Deleted; never used.
5779 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5780 on the Tcl/Tk source any more.
5781 (INCLUDE_CFLAGS): Remove references to the above.
5783 * Makefile.in (version.o): Corrected dependencies.
5785 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5787 * libguile.h: #include "version.h"
5789 * init.c (scm_boot_guile): Call scm_init_version.
5790 * gscm.c (gscm_run_scm): Call scm_init_version.
5792 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5793 GUILE_VERSION): AC_DEFINE these.
5794 (acconfig.h): #undef the above symbols.
5796 * Makefile.in (libobjs): Add version.o.
5797 (installed_h_files): Add version.h.
5798 (c_files): Add version.c.
5799 (gen_c_files): Add version.x.
5800 (version.o): New rule.
5801 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5802 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
5803 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
5804 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
5805 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
5806 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
5807 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
5808 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
5809 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
5810 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5811 weaks.o): Add version.h to dependency lists.
5812 (markers.o): Remove duplicate rule.
5814 * version.h: New file.
5816 * version.c: New file.
5818 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5820 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5821 array; use it appropriately. Since GCC is quite happy to
5822 subscript functions, it never warned us about this; we should use
5823 -Wpointer-arith in the future. I guess we never tested
5826 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5828 * socket.c: Doc and copyright fixes.
5830 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5832 * debug.c: Fixed and improved gdb support.
5834 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5836 * socket.c: Added declaration of inet_aton to avoid compiler
5837 warning. (Hope this solution is correct.)
5839 * stime.c: Added declaration of ftime. (This is missing in
5842 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5844 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5846 * Makefile.in (c_files): add strerror.c.
5848 * strerror.c: new file from Emacs' sysdep.c.
5849 maybe configure should also check for sys_errlist.
5851 * configure.in (AC_REPLACE_FUNCS): add strerror.
5853 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5855 * debug.c (scm_init_debug): Added initialization for
5856 scm_evaluator_traps.
5858 * debug.h, debug.c: Various name changes.
5859 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5860 "debug-options-interface". See commentary in options.c.
5862 * options.h, options.c: Options now have documentation strings.
5863 Also added a long explanatory commentary.
5865 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5868 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5869 last_debug_info_frame is now updated in all cases.
5871 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5874 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5876 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5877 Added option STACK_CHECKING.
5879 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5881 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5883 * __scm.h: Removed symbols for debugging support.
5885 * acconfig.h: Added symbols for debugging support.
5887 * configure.in: Added user option for debugging support.
5888 --enable-debug will include the debugging code into libguile.a.
5890 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5891 scm_relocate_chunk_to_heap.
5893 * debug.c: New file: low-level debugging support. It also
5894 includes support for debugging with gdb. (The extensions to gdb
5895 are written by Per Bothner at Cygnus.)
5897 * debug.h: New file: low-level debugging support.
5899 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5900 argument pairs. Extensive modifications to the debugging
5901 evaluator. Added "SECTION:" commentaries to clarify what happens
5902 when, during double compilation. Renamed EVALIMP --> EVALIM.
5903 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5904 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5905 the beginning of the file. New procedure: scm_unmemocopy.
5906 Added some global state variables needed by the debugging
5907 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5908 check_entry, check_apply, check_exit, debug_options and
5909 evaluator_traps. New acro: undefine.
5911 * eval.h: Renamed EVAL --> XEVAL.
5913 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5914 --> scm_make_weak_key_hash_table.
5916 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5917 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5919 * libguile.h: Conditionally include debug.h
5921 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5922 scm_object_properties shouldn't return handle. `handle' now gets
5923 initialized in scm_set_object_properties_x. scm_object_properties
5924 doesn't any longer create an entry in scm_object_whash.
5926 * options.c: New file: handling of run time options.
5928 * options.h: New file: handling of run time options.
5930 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5932 * print.c: New procedure: scm_print_options
5934 * print.h: Defines for print options.
5936 * read.c: New procedure: scm_read_options
5938 * read.h: Defines for reader options.
5940 * root.h: Added scm_source_whash among scm_sys_protects.
5942 * srcprop.c: New file: source properties.
5944 * srcprop.h: New file: source properties.
5946 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5947 (Bug found by A. Green.)
5949 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5951 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5953 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5955 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5957 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5958 and should be called by the final client.
5960 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5962 * gc.h: Use the PROTO macro when declaring functions.
5963 * gc.c: Use the PROTO macro when declaring static functions.
5964 Remove the CPP hair around function definitions.
5966 * gc.c (scm_init_storage): Initialize scm_asyncs.
5968 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5969 preprocessor symbol; "__scm.h" is where it might get #defined.
5970 * __scm.h: Similar: #include <scmconfig.h> before testing
5973 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5975 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5977 * init.c (scm_boot_guile): Add init_func argument; call
5978 (*init_func) instead of calling scm_appinit; it's ucky to
5979 hard-code names for the user's procedures.
5980 * init.h (scm_boot_guile): Adjust declaration.
5982 * __scm.h (PROTO): New macro, for declaring functions with
5985 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5986 eliminate all the __STDC__ conditionals.
5987 (scm_boot_guile): Add declaration.
5988 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5989 Remove __STDC__ conditionals around function definitions; the
5990 declarations in init.h will provide the same information, more
5993 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5994 complain about it in the error message; the error message is
5995 adequate without that note, and there's nothing the user can do
5998 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
6000 * Makefile.in (ancillary): Drop def.sed.
6002 * posix.c (scm_init_posix): Use numeric values, rather than
6003 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
6004 F_OK. The symbols aren't available on some systems, and I'm
6005 pretty sure their values are fixed by common widespread practice.
6006 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
6008 More functions unavailable on some systems.
6009 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
6010 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
6012 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
6013 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
6014 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
6015 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
6016 stub that signals an error as the #else.
6018 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
6020 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
6022 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
6024 * unif.c: include ramap.h.
6026 * read.c (endif): case_insensative_p renamed case_insensitive_p.
6028 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
6030 * ports.c: include sys/ioctl.h.
6032 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
6034 * configure.in: check for sys/ioctl.h.
6036 * ports.c: include <malloc.h> not "malloc.h".
6038 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6040 * fports.c: remove ttyname and tmpnam declarations.
6042 * posix.c: fewer ttyname declarations.
6044 * fports.c: include <string.h> not "string.h".
6046 * init.c, ioext.c: include string.h and unistd.h.
6048 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6050 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
6051 genio.c, simpos.c, vports.c: include string.h.
6053 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
6055 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
6057 (scm_addr_buffer_size): change type from scm_sizet to int.
6058 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
6059 from scm_sizet to int.
6061 * error.c: include unistd.h.
6063 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
6066 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
6068 * __scm.hd, def.sed: deleted.
6070 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
6072 Changes for NeXT, suggested by Robert Brown.
6073 * configure.in: Call AC_TYPE_MODE_T.
6074 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
6075 NeXT. Put header file list in alphabetical order.
6076 * configure, scmconfig.h.in: Regenerated.
6077 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
6079 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
6082 * acconfig.h: New file, providing documentation for the CPP
6083 symbols defined in configure.in
6084 * acconfig-1.5.h: Removed; superceded by the above.
6086 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
6088 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
6090 * fports.c (scm_open_file): don't return #f, throw error.
6092 * ioext.c (fileno): renamed from %fileno.
6093 (soft-fileno): deleted.
6095 * ports.c (scm_port_revealed): don't need to check for -1 from
6097 (scm_set_port_revealed_x): return unspecified, not #f.
6099 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
6101 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
6103 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
6105 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
6107 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
6109 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
6110 This is necessary on Ultrix, and doesn't hurt portability.
6112 * Makefile.in (dist-dir): New target, implementing a new dist system.
6113 (installed_h_files): Put in alphabetical order.
6114 Remove duplicate entries for markers.h and unif.h.
6115 (c_files): Remove duplicate entries for markers.c.
6116 (ancillary): Renamed from anillery; all uses changed. Remove
6117 PLUGIN; it's a directory, and needs special treatment in dist-dir.
6118 Remove all the ../doc/* files; doc/Makefile.in handles that.
6120 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
6122 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
6123 every if must have an else, or else the whole command has a
6124 non-zero exit code whenever the if's condition is false.
6126 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
6128 * posix.c: include string.h.
6130 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
6132 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
6135 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
6136 Remove leading % from scheme names.
6137 Do not return error values, call SCM_SYSERROR or similar.
6139 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
6141 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
6143 * struct.c (scm_init_struct): new file.
6145 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
6147 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
6148 (scm_list_head): added list-head for rapidly chopping argument
6149 lists off of longer lists (and similar).
6151 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
6153 * objprop.c (scm_object_property): assq the cdr of the whash
6154 handle for obj, not the handle itself.
6156 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
6158 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
6159 weak hash tables last of all marking to avoid an obscure gc bug.
6160 WARNING: circular lists stored in a weak hash table will hose us.
6162 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
6164 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
6165 new functions similar to scm_substring_move_left_x and
6166 scm_substring_move_right_x.
6168 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
6170 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
6173 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
6175 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
6177 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
6179 * strports.c (scm_strprint_obj): convenience function. C for
6180 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
6182 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
6183 removed to a separate library
6185 * init.c (scm_boot_guile): copied from guile-tcl.c.
6186 Initialization specific to tcl interpreters removed.
6188 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
6190 * ports.c (scm_ports_prehistory): size malloced here doesn't
6191 matter so long as it is non-0 (got rid of "* 4").
6193 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
6195 * gscm.h: gscm_mkarray eliminated (presumably was not being used
6196 since its definition was bogus).
6198 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
6200 * mallocs.[ch]: back again (for rx at least).
6202 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
6204 * ports.c: removed functions relating to the mapping between ports
6205 and descriptors. (That stuff is unix-specific and should be collected
6206 in a separate library).
6208 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
6209 (Tom Mckay@avanticorp.com)
6211 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
6213 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
6214 handled correctly (SCM_FREEP was applied to them) -- test for
6215 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
6216 being overwritten with #f. (brown@grettir.bibliotech.com)
6218 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
6220 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
6221 for a specific symbol or for all symbols.
6223 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
6225 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
6226 keys and weak values confused).
6228 Thu Mar 14 22:20:20 1996 Tom Lord <lord@beehive>
6230 * list.c (scm_last_pair): map '()=>'()
6232 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>
6234 * pairs.c, hashtab.c, list.c, alist.c append.c, sequences.c:
6235 Generalized assoc and hash-table functions.
6236 Factored pairs.c into multiple files.
6238 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
6240 * gscm.c (gscm_run_scm): got rid of objprop.
6242 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
6244 * genio.c (scm_getc):
6245 NOTE: fgetc may not be interruptable.
6247 * procprop.c (scm_stand_in_scm_proc):
6248 NOTE: don't use a alist here.
6249 (scm_set_procedure_properties_x): fix type checking throughout this file.
6251 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
6253 * ports.c (scm_remove_from_port_table): adjust scm_mallocated

6383 initialization to fix a race condition.
6385 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
