1 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
4 Replaced by macro `collect' in boot-9.scm.
6 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
8 * eval.c (scm_copy_tree): Copy source properties if existent.
10 * debug.c (scm_start_stack): Copy source when evaluating. (If we
11 don't, we may end up passing memoized source to a transformer.)
13 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
15 * stack.c (get_applybody): Help function which lookups the first
16 body form of the apply closure.
17 (read_frames): Prevent the source of the first form of the apply
18 closure from being recorded. This would only be confusing.
20 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
21 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
23 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
25 * stacks.c (read_frame): Bugfix: Removed lingering `else'
27 (read_frames): Use SCM_MACROEXPP.
29 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
31 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
32 don't contain interesting information since all arguments are
33 present in the frame which applies the compiled closure anyway.);
34 Skip the transformer application frames.
36 * print.c (scm_iprin1): Print gsubrs as primitives.
38 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
40 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
42 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
43 that we can identify these in a backtrace. (This change doesn't
44 introduce any significant speed penalty.)
46 * eval.c: Added note about `serial-map' using scm_map.
48 * read.c, read.h (scm_read_options, scm_read_opts): Removed
49 readline options. They should reside in their own options array.
51 * readline.c, readline.h (scm_readline_options,
52 scm_readline_opts): Moved readline options here.
54 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
56 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
57 SCM_ROCHARS instead of SCM_CHARS.
59 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
60 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
62 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
64 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
65 This is quite important since the latter clears the
66 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
67 every single character read...
69 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
71 * print.c (scm_iprin1): Removed suspect looking (and indeed
72 malevolent) semicolon after test for user supplied closure print
73 procedure. (Thanks to Telford Tendys.)
75 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
76 (scm_memq, scm_memv, scm_member): Do argument checking *before*
77 starting to search the list. Removed call to sloppy_mem_check.
79 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
80 procedures: Same as scm_delq_x et al, but delete maximally one
83 * options.c (scm_options, scm_init_options): GC-protect option
84 values of type SCM. (Thanks to Telford Tendys.)
86 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
88 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
89 make sure that there always is a "real" scm_lookupcar.
91 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
93 * read.c, read.h (history-length, history-file): New read options.
94 (scm_read_options): Stifle history to history length.
96 * readline.c (scm_read_history, scm_write_history): New
99 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
101 * eval.h (scm_macro_eval_x): Removed declaration.
103 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
104 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
105 Renamed and made global.
107 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
108 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
110 * evalext.c, evalext.h: New files. Contain non-R5RS things
111 having to do with evaluation.
113 * evalext.c (scm_serial_map): New procedure: Version of `map'
114 which guarantees that the procedure is applied to the lists in
116 (scm_m_sequence_to_list): New syntax: Version of `begin' which
117 returns a list of the results of the body forms instead of the
118 result of the last body form.
119 (scm_definedp, scm_m_undefine): Moved from eval.c
121 * evalext.h (scm_m_sequence_to_list): Added declaration.
123 * macros.c, macros.h: New files.
124 (scm_procedure_to_syntax, scm_procedure_to_macro,
125 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
126 scm_macro_name, scm_macro_transformer): Moved from eval.c
127 (scm_make_synt): Moved from eval.c
129 * procs.c, procs.h (scm_procedure_documentation): Moved from
132 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
135 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
137 * debug.c, print.c: Added #include "macros.h".
139 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
141 This change adds the ability to use `unread-char' multiple times
142 without interspersed reads and adds the new procedure
143 `unread-string'. The change is optimized for the common case of
144 unreading a single character. This is also the reason behind the
145 choice to store characters in the port itself: in most cases no
146 extra malloc is required.
148 The amount of code in some macros in ports.h has been increased to
149 the extent that they would fit better as C functions, but, since
150 this code belongs to the port representation, such functions
151 should be placed in ports.c which would cause calls back and forth
152 between ports.c and genio.c. That is not good for performance.
153 Also, keeping them as macros allows the compiler to do some
154 optimizations which are needed to make the current interface
155 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
157 One benchmark (Guile startup time) indicates an increase of
158 loading speed of 1%. Another (reading (using `read') boot-9.scm
159 10 times) shows no change in performance.
161 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
162 made to find a beautiful solution.)
164 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
165 (SCM_TRY_CLRDY): New macro: Only clear the first unread
166 character. (SCM_CLRDY clears all.)
167 (SCM_N_READY_CHARS): New macro: Returns number of unread
168 characters in a port. Returns wrong answer if SCM_CRDYP is false.
169 (struct scm_port_table): New fields: `entry' contains port table
170 index, `cp' points to last unread char, `cbuf' is the buffer for
171 unread chars, `cbufend' points after end of the character buffer.
173 * ports.h, ports.c (scm_unread_string): New procedure.
174 (scm_grow_port_cbuf): New function.
176 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
178 (scm_generic_fgets), fports.c (local_fgets): Use a loop
179 to read unread characters. Use SCM_TRY_CLRDY instead of
182 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
184 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
186 * genio.c, genio.h (scm_ungets): New function.
188 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
191 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
193 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
194 declarations. (Thanks to Russ McManus.)
196 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
198 * numbers.c (num2long): As a software archeologist, I'm proud of
199 this finding! :) Preliminary dating suggests an almost 4 year old
200 remnant from the SCM ancestor. The sample has been removed from
201 the finding site and is now safely stored in the repository.
203 * numbers.h: Removed prototype for num2long.
205 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
207 * gh_data.c (gh_scm2doubles): Make it possible to pass result
209 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
210 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
211 * gh.h: Updated and added prototypes.
213 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
215 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
217 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
219 * guile-snarf.in: Never generate an empty file. (Thanks to
222 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
223 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
224 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
225 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
226 gh_new_procedure5_0): Specify argument types, to appease C++
227 compilers. (Thanks to Brad Bowman.)
229 Bug reports from Russ McManus:
230 * guile-snarf.in: If the CPP environment variable is set, use that
231 as the C preprocessor, instead of the preprocessor autoconf
233 * snarf.h (SCM_PROC): Cast the function pointer passed to
234 scm_make_gsubr, to satisfy C++.
236 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
237 Use the handler passed, instead of ignoring it and using
238 gh_standard_handler. (Thanks to Etienne Bernard.)
240 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
242 * ports.h: Put text after #endif in comment. (Thanks to Nicolas

265 * script.c (scm_compile_shell_switches): Define
266 use-emacs-interface in the root module, so the repl code can see
267 it. See today's change to top-repl in ice-9/boot-9.scm.
269 * filesys.c (set_element, get_element): Make sure that `element'
270 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
271 Boekemeier and Jorgen "forcer" Schaefer.)
273 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
275 * chars.c (scm_charnames): In ASCII character name table, make
276 newlines print as #\newline by default, not #\nl.
278 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
279 alphabetical order. Oh thrills. But it helps me know how far
280 along in the compilation I am.
281 * Makefile.in: Regenerated.
283 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
285 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
286 #bytes(...) to #y(...), and syntax for short vectors from
287 #short(...) to #h(...). This may seem nutty, but, like the other
288 uniform vectors, byte vectors and short vectors want to have the
289 same print and read syntax (and, more basic, want to have read
290 syntax!). Changing the read syntax to use multiple characters
291 after the hash sign breaks with the conventions used in R5RS and
292 the conventions used for the other uniform vectors. It also
293 introduces complexity in the current reader, both on the C and
294 Scheme levels. (The Right solution is probably to change the
295 syntax and prototypes for uniform vectors entirely.)
297 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
299 Don't use local_fgets on sockets; ftell doesn't work on sockets.
300 (Thanks to Jorgen "forcer" Schaefer.)
301 * ports.h (SCM_NOFTELL): New flag.
302 * fports.c (local_fgets): If it's set, use the generic fgets.
303 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
305 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
307 * script.c (scm_compile_shell_switches): Add handling of -q switch
308 (inhibit loading of user init file).
309 (scm_shell_usage): Add usage text for -q switch.
310 (scm_compile_shell_switches): Always load user init file first if
313 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
315 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
316 and is now broken under NetBSD. I can't fathom what it's trying
317 to do, so I've replaced it with something that I do understand,
318 which seems to work, and which isn't broken on NetBSD. "Progress?
319 You Decide." (Thanks to Perry Metzger.)
321 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
322 signed/unsigned comparison.
324 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
326 Warning fixes from Greg Harvey:
327 * unif.c (scm_array_set_x): initializer for pos
328 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
329 * struct.c (scm_struct_ref, scm_struct_set_x): Added
330 initializers for field_type, since EGCS so desparately wants to
332 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
333 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
334 when GUILE_DEBUG is defined.
335 * dynwind.h (scm_wind_chain): Same.
336 * ports.h (scm_pt_size, scm_pt_member): Same.
337 * print.h (scm_current_pstate): Same.
338 * procs.h (scm_make_cclo): Same.
340 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
342 Handle short and long long uniform arrays properly. (Thanks to
344 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
345 raeql_1): Add cases for scm_tc7_svect (short vectors) and
346 scm_tc7_llvect (long long vectors).
348 Change the way libguile and boot-9.scm are timestamped, to try to
349 get rid of these spurious mismatch warnings. Now both
350 libguile/versiondat.h and ice-9/version.scm are generated directly
351 by the configuration process, rather than having version.scm
352 generated directly, and libguile/versiondat.h generated by the
353 Makefile, which is generated by configure. It seems that
354 sometimes the Makefile would change, but versiondat.h depends on
355 Makefile.in, not Makefile, so it wouldn't get rebuilt.
356 * Makefile.am (versiondat.h): Target removed; this is generated
357 directly by the configure script now.
358 (BUILT_SOURCES): Remove versiondat.h.
359 * versiondat.h.in: New file, transformed by the configure script
361 * Makefile.in: Regenerated.
363 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
364 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
365 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
366 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
367 if we want to use them in a header file some day, we can. (Thanks
370 * stime.c (scm_get_internal_real_time): Do the arithmetic using
371 SCM numbers, so we won't have rollover problems; the range of a
372 signed long in milliseconds is about 25 days. (Thanks to Karl
375 Don't redefine sleep and usleep; fix this problem now.
376 * coop.c (sleep, usleep): Remove declarations; we don't use or
377 redefine these any more.
378 (scm_thread_usleep, scm_thread_sleep): New functions which do the
379 job of usleep and sleep in a thread-friendly way. We can use
380 these in the rest of Guile. Define versions for systems both with
382 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
383 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
384 we're just using it, not redefining it, we can use a K&R style
386 (sleep): Declare this, too, if the system hasn't.
387 (scm_sleep, scm_usleep): Use scm_thread_sleep and
388 scm_uthread_sleep if they're available; otherwise, just call the
390 * scmconfig.h.in: Regenerated.
392 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
394 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
396 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
398 * threads.c: Doc fix.
400 The argument type of usleep varies from system to system,
401 as does the return type. We really shouldn't be redefining usleep
402 at all, but I don't have time to clean that up before the 1.3.
403 release. It's on the schedule for afterwards. (Thanks to Julian
405 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
407 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
408 * scmconfig.h: Regenerated.
410 * simpos.c (scm_software_type): Procedure deleted. This isn't the
411 right way to handle system variation. Autoconf's approach is the
413 * simpos.h (scm_software_type): Declaration deleted.
415 * script.c (scm_find_executable): Don't test if unix is #defined
416 here; first, NetBSD doesn't #define it, and second, it's the wrong
417 way to go about these things. (Thanks to Perry Metzger.)
418 (dld_find_executable): Delete this MSDOS support code. This isn't
419 the way we want to support this; it needs to be rethunk at a
422 * genio.c (scm_do_read_line): Don't just politely check that the
423 line was either non-empty or EOF. Abort if it's empty and not
426 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
428 * scmconfig.h.in: Regenerated.
430 * libguile.h: Don't omit the dynamic linking functions. (Thanks
433 * genio.c (scm_do_read_line): Count lines correctly when the file
434 doesn't end in a newline.
436 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
438 * genio.c (scm_do_read_line): Maintain the line count correctly.
439 (Thanks to Harvey J. Stein and Greg Harvey.)
441 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
444 * numbers.c (big2str): Protect t from garbage collection until
445 we're done. (Thanks to Gary Houston.)
447 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
449 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
451 * Makefile.in: Regenerated.
453 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
454 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
457 Do magic to mix reads and writes on stdio FILE-based ports.
458 (Thanks to Christian Lynbech.)
459 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
461 (pre_read, pre_write): New functions.
462 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
463 local_fputs): Call them.
464 (local_fflush): Mark the port as ready for reading and writing.
465 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
466 flags on new port objects. This might not be accurate --- who
467 knows what state the FILE * is in when we get it --- but it won't
468 do extraneous calls to fflush or fseek, so it's no worse than the
469 behavior before this change.
470 * ports.h: Add comment.
472 Centralize the creation of port objects based on stdio FILE * in
473 fports.c; don't just throw them together anywhere.
474 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
475 what the rest of Guile wants. Don't set the revealed count;
476 that's only appropriate for stdin, stdout, stderr.
477 (scm_standard_stream_to_port): This function does set the revealed
479 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
480 not scm_stdio_to_port.
481 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
482 * fports.c (scm_open_file): Same.
483 * posix.c (scm_pipe): Same.
484 * socket.c (scm_sock_fd_to_port): Same.
485 * ioext.c (scm_fdopen): Same.
486 (scm_freopen): Moved from here to...
487 * fports.c (scm_freopen): ... here. This is really something that
488 munges the internals of an fport, so it should go here.
489 * fports.h (scm_stdio_to_port): Adjust prototype.
490 (scm_standard_stream_to_port, scm_freopen): New protoypes.
491 * ioext.h (scm_freopen): Prototype removed.
493 * filesys.c (set_element, get_element): This can work on both pipe
494 and file ports, so use SCM_FPORTP to typecheck, instead of testing
497 * scmconfig.h.in: Regenerated.
499 Change the definition of the functions in scm_ptobfuns so that
500 they get passed the port object, not the port's stream.
501 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
502 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
503 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
504 Pass the port itself to the scm_ptobs function.
505 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
506 scm_generic_fgets): Same.
507 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
508 getc_void_port, fgets_void_port, close_void_port): Just change the
509 argument names; these functions don't really do anything.
510 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
511 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
512 port as an argument, and use SCM_STREAM to get the stdio FILE *.
513 Also, use prototyped definitions, and get rid of the extra
515 (scm_fptob, scm_pipob): We don't need casts here any more.
516 * strports.c (prinstpt): Use prototype declarations.
517 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
518 and use SCM_STREAM to get the string info. Also, use prototyped
519 definitions, and get rid of the extra declarations.
520 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
523 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
524 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
526 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
527 scm_fgets, for consistency.
528 (scm_fptop, scm_pipob): References updated.
530 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
532 Include the source location in error messages for scripts.
533 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
534 stack is still there when we catch the error.
535 * throw.c (handler_message): If we are handling an error with a
536 message, then put together the proper arguments and call
537 scm_display_error, instead of scm_display_error_message. That
538 displays source location, if it can find it.
540 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
542 * gc.c (scm_unprotect_object): Change this so that calls to
543 scm_protect_object and scm_unprotect_object nest properly.
544 (scm_protect_object): Doc fixes.
546 * strings.c (scm_string_set_x): Require the argument to be a
547 writable string, not a substring or a symbol.
548 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
549 (Thanks to John Redford and Charbel Jacquin.)
551 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
553 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
555 * eval.c (safe_setjmp): Remove this misunderstanding.
556 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
559 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
561 * libguile.h: Mark these as C declarations, for compilation by C++
564 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
565 __cplusplus clause. I seriously doubt this ever worked the way
566 the author seems to have intended.
568 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
570 Utterly needless cleanups to hopelessly messy code.
571 * ports.c: Doc fixes.
572 (scm_fflush): Moved to ...
573 * genio.c (scm_fflush): ... here, amongst all the other port
574 method invocation functions.
575 * genio.h, ports.h: The prototype moves too.
577 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
579 * backtrace.c (display_error_body): The current frame does not
580 always have a parent frame; consider a function called directly
581 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
584 * alloca.c (alloca): Undo yesterday's changes, and simply call
585 malloc directly for storage, and abort if we don't get what we
586 want. The situation is much simpler --- just call malloc. Emacs
587 has bizarre/evil requirements (signal handlers might malloc unless
588 you set this global flag, so you have to set the flag around all
589 calls to malloc) which we are certainly not going to conform to,
590 so we can do the simple and obvious thing.
592 * coop.c (coop_condition_variable_wait): Make this function
593 static. It's only useful internally --- you should never just
594 wait on a condition variable.
595 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
597 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
599 * unif.c (scm_array_set_x): Accept any kind of number as an
600 element for a uniform vector of doubles. This is more consistent
601 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
603 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
604 works; I can't conveniently test it myself. (Thanks to Dvid
605 Tillman for the bug report.)
609 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
610 from here, not from scm_compile_shell_switches (which is a pretty
611 dumb place to do it).
612 (scm_load_startup_files): New function.
613 (scm_ice_9_already_loaded): Variable moved to here from script.c.
614 * script.c (scm_compile_shell_switches): Don't load the startup
616 (scm_ice_9_already_loaded): Variable moved.
617 * init.c (scm_load_startup_files): Prototype for new function.
618 * gh_init.c (gh_enter): Doc fix.
620 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
622 Some anti-warning changes from Greg Harvey.
623 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
624 warnings when it doesn't understand our NORETURN declarations in
626 * posix.c (scm_mknod): Similar.
628 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
630 * posix.c (scm_getpwuid): If we can't find an entry, return our
631 own message, instead of using scm_syserror --- the getpwMUMBLE
632 functions don't set `errno' to anything interesting.
634 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
636 Get rid of warnings from the cooperative threading system.
637 * threads.h (scm_single_thread_p, scm_yield,
638 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
639 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
640 scm_wait_condition_variable, scm_signal_condition_variable): Add
641 prototypes for these Scheme-visible functions.
642 * coop-defs.h (coop_next_runnable_thread,
643 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
644 Prototypes for these here, even though they're from iselect.c.
645 (coop_condition_variable_wait, coop_join): Add prototypes.
646 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
647 scm_threads_free_condvar): Make these smob functions static.
648 * coop-threads.h (coop_init): Give this a real prototype.
649 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
650 (coop_next_runnable_thread): No need to provide prototype; it's in
653 * scmconfig.h.in: .detarenegeR
655 * iselect.c, threads.c: Doc fixes.
657 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
659 * Makefile.in: Regenerated with a patched automake, to get
660 dependency generation right when using EGCS.
662 * inet_aton.c (inet_aton): Add prototype, to remove compiler
663 warning. (Thanks to Robert Pluim.)
665 * inet_aton.c (inet_aton): Reassure the compiler that the
666 arguments to the <ctype.h> macros are all unsigned characters, not
669 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
671 Getting rid of more warnings...
672 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
673 today's change to ../configure.in.
674 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
675 * scmconfig.h.in: Regenertaded.de.,.__
676 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
677 (scm_localtime, scm_mktime): Use a const char * to manipulate the
680 * readline.c: Doc fix.
681 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
682 * readline.h (scm_filename_completion_function): Add prototype.
683 (scm_init_readline): Make this into a prototype.
685 * readline.c (scm_filename_completion_function): Use SCM_PROC to
686 declare this, instead of calling scm_make_subr manually.
688 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
690 * readline.h (scm_init_readline): Add prototype for this.
691 (scm_init_readline): Make this a real prototype.
693 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
695 Warning fixes from Maciej Stachowiak:
696 * backtrace.h (scm_display_application, scm_backtrace): Add
698 * debug.c (scm_m_start_stack): Make this function static.
699 * fluids.h (scm_fluid_p): Add prototype.
700 * procprop.c (scm_i_procedure_arity): Make this function static.
701 * regex-posix.c (scm_regexp_error_msg): Make this function static.
702 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
703 * root.h (scm_dynamic_root): Add external prototype.
704 * scmsigs.h (scm_usleep): Add external prototype.
705 * script.h (scm_init_script): Use prototype, not K&R decl.
706 * stacks.h (scm_stack_id): Add external prototype.
707 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
709 1998-09-30 Mark Galassi <rosalia@cygnus.com>
711 * gh.h: took out the definitions of vset and vref, since they are
712 replaced by the proper vector routines that correspond to the R4RS
715 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
717 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
718 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
719 third argument, a C expression that should result in a SCM value,
720 which is used to initialize the variable. Reimplemented
721 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
724 * version.h (scm_libguile_config_stamp): Add prototype.
725 (From Maciej Stachowiak.)
727 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
729 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
730 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
732 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
734 * print.c (scm_iprin1): Rather than having one i, and using it in
735 several places, declare a fresh i local to each block where it is
736 used, and give it a signedness appropriate to its use in each case.
739 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
742 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
743 signed/unsigned clashes.
745 * posix.h (scm_tmpnam): Added prototype.
747 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
748 scm_make_subclass_object): Add external prototypes.
750 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
751 comparison is okay here.
753 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
755 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
756 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
758 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
761 * load.c (swap_port): Make this function static.
763 * load.c (scm_search_path): Make max_path_len and max_ext_len
764 unsigned, since they're compared against string sizes.
766 * load.c (init_build_info): Make i unsigned.
768 * ioext.h (scm_read_line): Add prototype.
770 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
771 scm_hash_fn_remove_x): Make hash bucket index local variable k
772 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
773 accurately as possible.
775 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
776 comparisons, and range checking to make sure those casts are
779 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
780 signed/unsigned comparisons.
782 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
783 avoid signed/unsigned comparisons.
784 * smob.h (scm_numsmob): Change extern declaration to match.
786 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
787 avoid signed/unsigned comparisons.
788 * ports.h (scm_numptob): Change extern declaration to match.
789 (scm_current_load_port, scm_set_port_line_x,
790 scm_set_port_column_x): New prototypes.
792 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
793 test code, and it causes warnings.
795 * gh.h (gh_int2scmb, gh_uniform_vector_length,
796 gh_uniform_vector_ref): Added prototypes.
798 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
799 debugging support unconditionally. That's backtrace.c, stack.c,
800 debug.c, and srcprop.c.
801 (EXTRA_libguile_la_SOURCES): Omit those from here.
802 * Makefile.in: Regenerated.
804 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
806 * options.c (scm_options): Bugfix: Allow empty list of options!
808 * debug.c, debug.h (scm_single_step): Removed.
809 (scm_with_traps): New procedure. This procedure could easily be
810 written in Scheme but needs to be highly optimized.
812 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
814 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
815 Check SCM_TRAPS_P before trapping.
817 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
819 Changes to avoid signed/unsigned comparison warnings.
820 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
821 (scm_gc_sweep): Make n and j local to the blocks they're used in,
822 so they can have appropriate types for each application. Make i
823 signed. Use initializers in some spots. I'll probably pay for
825 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
826 (scm_must_realloc): Make nm unsigned.
827 (init_heap_seg): Make new_seg_index and n_new_objects signed.
828 (scm_init_storage): Use prototype-style definition, and make the
830 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
831 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
833 * filesys.c (scm_readlink): Make local vars rv and size ints, to
834 avoid signed/unsigned comparison warnings, and because the return
835 value of readlink may be -1. Don't bother casting the third
836 argument to readlink.
838 * filesys.c (scm_dirname, scm_basename): Move these to their own
839 page, at the end of the file.
840 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
842 * eval.h (scm_eval_options_interface): Add external prototype for this.
843 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
845 * eval.c (scm_lookupcar1): Make this static.
847 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
848 Make these prototype declarations, not K&R-style.
850 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
851 unsigned comparison warning.
853 * appinit.c: File removed. It had a single function in it, empty,
854 whose reason for existence is explained in no documentation or
855 comment. I think it's there as a default for some Tcl-style
856 initialization, but Tcl abandoned that approach a while ago.
857 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
858 (BUILT_SOURCES): Remove appinit.x.
859 * Makefile.in: Regenerated.
861 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
863 * Makefile.in: Regenerated using the last public version of
864 automake, not the hacked Cygnus version.
866 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
868 Remove Totoro kludge.
869 * Makefile.in, scmconfig.h.in: Regenerated.
870 * init.c, readline.c: Don't check if TOTORO is #defined.
872 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
874 * Makefile.am: Adjust for new thread configuration system.
875 (INCLUDES): Include the value of THREAD_CPPFLAGS.
876 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
878 (THREAD_LIBS): Definition deleted; automake will generate such
879 things automatically.
880 * Makefile.in: Regenerated.
882 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
884 Simplify smob and port marking; set the mark bit in the generic
885 marking code, and make marker routines only responsible for
886 turning up outgoing pointers.
887 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
888 before calling the marking function. Don't call the marking
889 function if it's zero.
890 * markers.c (scm_mark0): Just return #f. This function isn't
891 necessary at all now, but it's harmless to call it. We'll leave
892 it in so other folks' code doesn't croak at link time.
893 (scm_markcdr): Don't call SCM_SETGC8MARK.
894 * async.c (mark_async): Don't call SCM_SETGC8MARK.
895 * dynl.c (mark_dynl_obj): Same.
896 * root.c (mark_root): Same.
897 * srcprop.c (marksrcprops): Same.
898 * unif.c (markra): Same.
899 * variable.c (scm_markvar): Same.
900 * ports.c (scm_markstream): Same.
901 (void_port_ptob): Specify zero for our marking function.
902 * debug.c (debugobjsmob): Same.
903 * dynwind.c (guardsmob): Same.
904 * filesys.c (dir_smob): Same.
905 * fluids.c (fluid_smob): Same.
906 * fports.c (scm_fptob, scm_pipob): Same.
907 * mallocs.c (mallocsmob): Same.
908 * regex-posix.c (regex_t_smob): Same.
909 * smob.c (freecell, flob, bigob): Same.
910 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
911 * throw.c (jbsmob, lazy_catch_funs): Same.
913 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
915 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
916 scm_copy_tree on code in order not to let memoized code to leak
917 out. Thus, scm_copy_tree needs to copy vectors as well since
918 quasiquote can introduce evaluated code also inside vector
921 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
923 * eval.c (scm_copy_tree): Removed ability to copy vectors.
925 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
926 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
929 * unif.c: Say that ivect and uvect are of type signed and unsigned
930 long instead of int in commentary so that it correctly describes
933 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
935 * stime.c: Removed declaration of strptime. (It should be
936 declared by the system headers. If it turns out that some systems
937 don't, we'll handle that then.) (Thanks to Greg Troxel.)
939 * stime.h: Renamed TIMEH --> STIMEH
941 * backtrace.c (scm_display_error, scm_display_backtrace): In order
942 to increase portability, don't use structure assignment.
943 (Thanks to Nicolas Neuss.)
945 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
947 (finalize_fd_sets): Added empty statement after last case label.
948 (Thanks to Nicolas Neuss.)
950 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
953 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
955 * init.c, readline.c: OK, I won't have these readline.x bug
956 reports anymore. We've had them since April. The current reason
957 is a completely unintelligible failure of totoro.red-bean.com to
958 do the test for rl_getc_function in libreadline correctly. This
959 kludge overrides the test if we're on totoro so that the snapshot
960 generation process can work.
962 * readline.c: Define a strdup replacement if not existent on system.
964 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
966 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
967 This change makes scm_make_vector R5RS compatible. We cannot keep
968 the third argument since people want to be able to deduce the form
969 of the C function call only by looking at R5RS. (At the same time
970 we have removed some unnecessary complexity!)
972 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
973 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
974 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
975 argument in call to scm_make_vector.
977 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
979 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
980 This macro is useful in applications.
982 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
984 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
985 (scm_parse_path, scm_search_path): New Scheme level procedures.
987 * load.h (scm_internal_parse_path, scm_parse_path,
988 scm_search_path): Declared.
990 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
992 * filesys.c (dirname, basename): New procedures.
994 * init.c (scm_boot_guile_1): Removed condition around
997 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
998 new data type (guards) for representation of C level guards and
999 data on the wind chain.
1000 (scm_internal_dynamic_wind): New function.
1002 * dynwind.h: Declare scm_internal_dynamic_wind.
1004 * root.h (scm_root_state): Added scm_cur_loadp.
1006 * root.c (mark_root): Added comment about cur_loadp.
1008 * load.c: #include "dynwind.h";
1009 (scm_primitive_load): Use scm_inner_dynamic_wind to update
1012 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
1014 * ports.c (current-load-port): New procedure.
1016 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1018 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
1019 not a tty, return #f.
1021 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
1022 to Julian Satchell and Roland Kaufmann.)
1024 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
1025 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
1027 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1029 * debug.h, debug.c (scm_start_stack): New function. Implements
1030 the guts of old scm_m_start_stack.
1032 * debug.c (scm_m_start_stack): Use scm_start_stack.
1034 * init.c (scm_start_stack, scm_restart_stack): Renamed to
1035 start_stack and restart_stack. (These have static scope.)
1037 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1039 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
1040 readline functions to come in release 2.3. (Thanks to Chet
1042 (handle_errors): Use the above functions.
1044 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1046 * readline.c: Improvements for readline support: Handle errors
1047 better; Implement before-read-hook.
1049 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1051 * init.c (scm_boot_guile_1), readline.c: Test for
1052 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
1053 assure that we have version >= 2.1.)
1055 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
1057 * readline.c (scm_readline): Defer interrupts while we're calling
1060 * readline.c (scm_add_history): Bugfix: Do strdup before giving
1061 away the string to add_history.
1062 (completion_function): Do completion for readline. (Thanks to
1064 (scm_filename_completion_function): New procedure: Filename
1066 (current_input_getc): New function. Use this one instead of
1067 standard getc from readline.
1069 * throw.c, throw.h (scm_handle_by_throw): New function: This
1070 handler throws errors to next handler on the dynwind chain.
1072 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
1074 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
1077 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1079 * procprop.c (scm_i_procedure_arity): New function. Returns arity
1081 (scm_procedure_properties): Modified to return arity together with
1083 (scm_procedure_property): Added the read-only property `arity'.
1084 (scm_set_procedure_property_x): It is an error to set the `arity'
1087 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
1088 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
1090 * procprop.h (scm_sym_arity): New symbol.
1092 * objects.c (scm_set_object_procedure_x): New procedure: Use this
1093 to set the dispatch procedure of an operator or entity object.
1095 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
1096 Made procedure slots read-only.
1098 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
1099 scm_tcs_cons_gloc case in zero args switch; Fixed args
1100 construction for operators in scm_tcs_cons_gloc case in two args
1103 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1105 * fluids.c: Removed use of assert.h (in order to avoid
1108 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
1110 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
1112 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
1113 change makes the evaluator safer at the cost of evaluation speed.
1114 It handles the case when the user has added a non-immediate
1115 improper end of the application form, e.g., `(+ 0 . x)'.
1116 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
1117 minimize the extra cost as much as possible. The new code is
1118 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
1119 problem with structs planted directly in the code (e.g. by a
1120 macro). This no longer causes segmentation fault. (Thanks to
1123 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
1124 arg `proc' in order to be able to throw errors; New argument
1127 * Removed extra #include "debug.h"
1129 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
1131 * scmsigs.c: Declare usleep as returning void on some systems.
1132 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
1135 * coop.c (usleep): Return void on some systems.
1137 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1139 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
1141 * coop.c: Changed return type of usleep to int.
1143 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
1144 isn't found in the OS.
1146 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
1147 isn't enabled. (Thought that I had made this change ages ago...)
1149 * iselect.c: Declare bzero if not defined by OS.
1151 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1153 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
1154 condition. (Thanks to John Tobey.)
1156 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
1157 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
1160 * __scm.h: Start the long-term project of moving to POSIX threads.
1161 Phase 1: Classification of all critical sections.
1162 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
1163 for A sections. (See comments in __scm.h for details.)
1165 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
1166 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
1168 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1170 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
1171 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
1172 (libpath.h, versiondat.h): Replaced dependency on Makefile with
1173 dependencies on $(srcdir)/Makefile.in
1174 $(top_builddir)/config.status in order to avoid circularity.
1176 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
1177 from argc if argc was 0 initially.
1179 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
1180 in generation of libpath.h.
1182 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
1184 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
1185 libguile from 2 to 3.
1187 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
1189 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
1191 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
1193 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
1194 scm_set_port_column_x, scm_port_filename,
1195 scm_set_port_filename_x): Removed optional arguments. Added
1196 proper argument checking.
1198 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
1199 stack size in machine words.
1201 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
1202 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
1203 to Ole Myren Röhne.)
1205 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
1207 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
1208 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
1210 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
1213 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
1214 procedure apply: Copy argument lists before pushing them unto the
1215 environment so that the environment won't get mutated due to
1216 manipulation of procedure arguments. This should perhaps be
1217 regarded as a temporary solution until someone finds a more
1218 efficient one. (Thanks to Maciej Stachowiak.)
1220 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
1222 * script.c (scm_compile_shell_switches): Use "guile" as default
1223 zero arg if argc is NULL.
1225 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
1227 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
1228 is zero. (Thanks to Dirk Herrmann.)
1230 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
1232 * ports.c (scm_add_to_port_table): First line is now line 0
1233 (was 1). (Interface changed according to suggestion by Per
1236 * backtrace.c (display_header): Add 1 to line and column numbers
1237 when presenting them to the user.
1239 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
1240 from debug.c --> eval.c
1242 * eval.h, eval.c (scm_eval_options_interface): New options
1244 (SCM_EVAL_STACK): New option: Size of newly created stacks,
1245 i.e. stacks for new threads.
1247 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
1249 * eval.c (unsafe_setjmp): Removed with #if 0.
1251 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
1254 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
1255 to avoid compiler warnings.
1257 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
1259 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
1261 * throw.c (handler_message): Print message on current error port
1262 instead of default error port. (Thanks to Maciej Stachowiak.)
1264 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
1266 * ports.c (scm_add_to_port_table): allocate in units of
1267 struct scm_port_table *, not struct scm_port_table.
1268 * posix.c (scm_close_pipe): remove the port from the port table
1270 Thanks to Rob Engle for both fixes.
1272 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1274 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
1275 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
1277 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1279 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
1281 * backtrace.c (display_error_body, display_backtrace_body),
1282 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
1283 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
1284 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
1285 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
1288 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
1289 don't receive the jmpbuf arg anylonger.
1290 (scm_catch): Don't accept a #f tag.
1291 (scm_throw): Check that key is a symbol.
1292 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
1294 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
1296 * async.c (async_pending): Removed declaration.
1298 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1300 * dynwind.c (scm_wind_chain): New debug function.
1302 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
1303 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
1304 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
1305 extra layer of functions around the body and handler of a thread.
1306 This extra layer makes sure that the handler is called in the
1307 dynamic context of the surround (= empty dynwind list), but under
1308 the *dynamic root* of the body. We can not use the dynamic root
1309 of the surround since that root belongs to another thread => stack
1310 is not handled correctly. It may seem ugly to use this extra
1311 layer, but the extra cost in terms of execution time is really
1312 negligible compared to the total amount of time required to create
1313 a thread, and it would reduce maintainability to duplicate the
1314 crucial and complicated steps performed by cwdr.
1316 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
1317 (SCM_ALLOW_INTS): Added thread switching code before interrupts
1318 get re-enabled. The important effect of this is that interrupts
1319 are blocked during thread switching so that thread data structures
1320 don't risk getting messed up by an unfortunate signal.
1321 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
1322 seems to do more aggressive optimization which actually move
1323 instructions around in these macros in a fatal way. Therefore:
1324 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
1325 just superstitious...)
1326 (SCM_TICK): Maybe do a context switch and take care of asyncs.
1327 This macro should be used instead of SCM_ASYNC_TICK since the
1328 latter doesn't do context switches any more.
1330 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
1331 instead of SCM_ASYNC_TICK.
1333 * coop.c, iselect.c: Since thread switches are now performed with
1334 interrupts masked, we can't use the old mechanism of delivering
1335 signals immediately when they arrive. Signals must instead be
1336 delivered when the asyncs run *after* the end of the critical
1337 section in scm_internal_select. But this also means after context
1338 switch so that the signal will be delivered to a different thread.
1339 To avoid this, I have changed the protocol of
1340 coop_wait_for_runnable_thread and friends so that they are allowed
1341 to return the original thread. So, if a signal arrives during
1342 scm_internal_select, we won't any longer be forced do a context
1343 switch, but can remain in the same thread and deliver the signal
1346 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
1347 scm_asyncs_pending and made it global.
1349 * iselect.c: Small fixes.
1351 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
1352 coop_condition_variable_init, coop_condition_variable_wait,
1353 coop_condition_variable_signal): Changed return type from `void'
1354 to `int'. This is to adhere closer to the pthreads interface.
1355 This, in turn, is part of an attempt to provide C versions of the
1356 mutex and condition variable primitives which can be part of a
1357 frontend to COOP or pthreads.
1359 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
1360 coop_condition_variable_destroy): New functions.
1362 * coop-threads.c (scm_wait_condition_variable): Use
1363 coop_condition_variable_wait_mutex.
1365 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
1366 Definitions moved to coop-defs.h.
1368 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
1369 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
1370 scm_cond_destroy): New C interface to mutecis and cond vars.
1372 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1374 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
1376 * iselect.c: Now several threads can wait on the same file
1377 descriptor. The behaviour is compatible with OS select: All
1378 threads waiting for the fd return with the same status.
1380 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1382 * coop-threads.c, threads.h (scm_spawn_thread): New function.
1383 Can spawn a thread from application C code.
1385 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1387 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
1388 gh_doubles2scm): New functions.
1390 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
1392 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
1393 commented-out version of gh_eval_str()
1395 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
1397 * socket.c (scm_bind): free soka after use.
1399 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
1401 * stime.c (tzvar): new variable.
1402 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
1403 avoid memory leaks when allocating.
1405 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
1407 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
1410 * gc.c, tags.h: Doc fixes.
1412 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1414 * eval.c (macro-eval!): Removed. This function was a design bug.
1415 It allowed memoized code to leak out to the scheme level. Most
1416 things that you could do with `macro-eval!' can be done with
1419 1997-12-20 Tim Pierce <twp@skepsis.com>
1421 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
1422 scm_fgets now depends on ftell(3) to know how many bytes were
1425 1997-12-15 Tim Pierce <twp@skepsis.com>
1427 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
1428 dealing with strings.
1430 1997-12-13 Tim Pierce <twp@skepsis.com>
1432 Make %read-line more suitable for implementing read-line efficiently.
1433 * ioext.c (scm_read_line): Strip the terminating newline from a
1434 string, and return a cons of the string and its terminator.
1436 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
1437 of the string that is read is stored in this memory location.
1438 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
1439 * genio.c, genio.h (scm_do_read_line): Update caller.
1440 * ports.h (scm_ptobfuns): Update typedef.
1441 * fports.c (scm_fptob, scm_pipob): Update struct.
1443 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1445 * filesys.c (set_element): Return file descriptor.
1446 (fill_select_type): Return the highest file descriptor.
1447 (scm_select): Tell select about the highest file descriptor. On
1448 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
1449 Therefore the extra overhead for calculating the maximum fd seems
1450 to be more than compensated. Is this correct? In any case,
1451 scm_internal_select will be much faster with this info.
1452 (scm_select, fill_select_type, set_element): Don't accept any kind
1453 of object in the file descriptor list or vector.
1455 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1457 * iselect.c (finalize_fd_sets): Bugfix.
1459 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1461 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1462 when using scm_internal_select (since we might switch to another
1465 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1467 * simpos.c (scm_system): always define: use sysmissing if not
1468 available. Check for HAVE_SYSTEM instead of _Windows (does
1469 Windows lack system or does it have an unusable one?).
1470 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1471 Let the argument be optional: if not supplied, call system(NULL).
1473 * ports.c (scm_close_port): relax the type check from OPPORTP to
1474 PORTP; closing a closed port is allowed.
1476 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1478 * fports.c (scm_fgets): Return if the last char in a chunk is
1479 newline. When fgets returns a string whose length is `size-1', it
1480 is ambiguous whether a whole line was retrieved, so we must check
1481 explicitly whether a line terminator is present.
1483 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1485 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
1486 before taking the CDR. (Thanks to Harald Meland.)
1488 * filesys.c (scm_stat): Slightly optimized.
1490 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
1492 * ports.c (scm_close_port): Make sure the port is open before
1495 * guile-snarf.in: Pass args through to gcc in a way that preserves
1496 whitespace boundaries. (Thanks to Greg Badros.)
1498 1997-12-02 Tim Pierce <twp@skepsis.com>
1500 * stacks.c (scm_frame_procedure): Reverse the logic in the return
1501 statement. (Thanks to Doug Evans for pointing this out.)
1503 1997-12-01 Tim Pierce <twp@skepsis.com>
1505 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
1507 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
1509 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
1510 errno macro expansion of this field name. (errno is a C
1511 preprocessor macro on some systems.)
1513 1997-11-29 Tim Pierce <twp@skepsis.com>
1515 * iselect.c: Doc fix.
1517 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
1519 * init.c (scm_start_stack): Removed initialization of
1520 scm_the_last_stack_var.
1522 * backtrace.h: Declare scm_the_last_stack_var.
1524 * backtrace.c: Define scm_the_last_stack_var.
1526 * root.c (mark_root): Don't mark the_last_stack_var.
1528 * root.h (scm_root_state): Removed the_last_stack_var.
1530 * throw.c: Added #include "fluids.h"
1531 (ss_handler): `the-last-stack' is now a fluid.

1534 --> the_last_stack_fluid.
1536 * backtrace.c: Added #include "fluids.h"

1540 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
1541 after scm_init_fluids.
1543 1997-11-28 Tim Pierce <twp@skepsis.com>

1550 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1552 * iselect.c (coop_next_runnable_thread,
1553 coop_wait_for_runnable_thread): Disable interrupts so that no
1554 async is executed before a potential error_revive.
1555 (scm_internal_select): Disable interrupts during the parts of the
1556 code which manipulate the sleep queue and the file descriptors.
1558 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1560 * Makefile.am: Added iselect.c and iselect.h.
1562 * coop.c (coop_qinit): Initialize fields used by
1563 scm_internal_select.
1564 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1565 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1566 replacement in iselect.c.
1567 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1568 coop_join): If GUILE_ISELECT enabled, use
1569 coop_wait_for_runnable_thread instead of
1570 coop_next_runnable_thread.
1571 (usleep, sleep): New replacements for system functions if
1572 GUILE_ISELECT is enabled.
1574 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1576 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1578 * filesys.c: Added #include "iselect.h". Moved FD-macros to
1579 iselect.h. Implement Scheme level `select' using
1580 scm_internal_select. (See NEWS.)
1582 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1584 * init.c: Call scm_init_iselect.

1589 1997-11-27 Tim Pierce <twp@skepsis.com>
1591 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1592 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1593 and scm_must_free, since ultimately the string returned will be copied
1594 by scm_makfrom0str anyway. Also, read any characters that may have
1595 been pushed onto the port with scm_ungetc.
1596 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1597 * ioext.c (scm_read_line): Free string after Guilifying it.

1609 gh_repl (argc, argv).
1611 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1613 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1614 and to invoke scm_shell().
1615 (gh_launch_pad): took out the loading of boot-9.scm from here,
1616 since it is probably best to let the user control that. In fact,
1617 gh_repl() now invokes scm_shell() which does that.
1619 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1621 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()

1643 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1644 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1646 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1648 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1649 configure.in was changed).
1651 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
1653 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1654 * Makefile.in: Regenerated.
1656 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1658 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1659 OPORT is an `open' port, not an output port.
1661 * filesys.c (scm_close, set_element, get_element, scm_chown,
1662 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
1663 SCM_COERCE_OUTPORT to cope with the printstate/port magic.

1667 scm_set_port_filename_x, scm_port_mode,
1668 scm_close_all_ports_except, scm_set_current_output_port,
1669 scm_set_current_error_port): Likewise
1670 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1671 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
1673 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
1674 * backtrace.c (display_backtrace_body): Likewise
1675 * fports (scm_setvbuf): Likewise
1676 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,

1683 Minor problems with substring-related tag changes.
1684 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1685 exactly what we want to leave in to detect substrings.
1686 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1687 * tags.h: Fix diagrams and comments describing the S tag bit;
1688 remove vestigial remarks about the D tag bit.

1690 * strings.c: Formatting tweaks.
1692 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1693 variable first; then SCHEME_LOAD_PATH, with a warning message.
1694 (scm_parse_path): New function.
1695 * script.c: Doc fixes.
1697 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1699 Readline support, from Daniel Risacher.
1700 * readline.c, readline.h: New files.
1701 * init.c: #include "readline.h".
1702 (scm_boot_guile_1): Call scm_init_readline, if we have it.
1703 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1704 * Makefile.in: Regenerated.
1705 * scmconfig.h.in: Regenerated, after change to ../configure.
1707 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1709 * gh.h: gh_vector_set -> gh_vector_set_x
1711 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1713 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1714 with the ! -> _x mapping when going from Scheme to C.
1716 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1718 * gh.h (gh_reverse):
1726 (gh_assoc): added these gh_ functions implemented as macros.

1729 (gh_string_equal_p): added these two missing predicates.
1731 * gh_list.c (gh_append):
1736 (gh_set_cdr_x): added these routines as I go through and try to
1737 complete the picture R4RS functions that should be mirrored in the
1740 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1742 * tags.h (scm_tc7_substring): Changed the comment and code to
1743 conform with the changes below. Folks! We have suddenly two new
1744 free tc7 codes!!! Jummy, jummy!
1746 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
1748 * Makefile.in: Rebuilt.

1775 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
1777 Don't include "mbstrings.h".
1778 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
1779 (SCM_SYMBOL_SLOTS): Define as 4.

1782 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
1783 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
1784 struct.c, threads.c, throw.c, unif.c, variable.c: Use new

1804 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1806 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1808 * gh_test_c.c (c_vector_test): some improvements on the vector
1811 * gh.h (gh_vector): this used to exist but do the wrong thing.
1812 Now it (almost) does the right thing, though it takes a list
1813 instead of the individual arguments. I need to see how it could
1815 (gh_list_to_vector): added this function as a macro. Corresponds
1816 to Scheme's (list->vector ...).
1817 (gh_vector_to_list): added this function as a macro. Corresponds
1818 to Scheme's (vector->list ...).
1820 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1821 gh_vector_ref, so that it resembles the Scheme routines more.
1822 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1823 resembles the Scheme routines more.
1824 (gh_make_vector): this used to be (stupidly) called gh_vector().
1825 This is the right name, since it does the same thing as the Scheme
1826 (make-vector ...) procedure.
1828 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1830 * ports.h: #include "libguile/print.h"

1843 gh_int2scmb(), which is now tagged as obsolete.
1845 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1847 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1848 macros should by convention not test for NIMPness.)
1849 (SCM_COERCE_OPORT): Adjust indentation.
1851 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1852 SCM_NIMP test before SCM_PRINT_STATE_P.
1854 * struct.c, struct.h, gc.c: Renamed:
1855 scm_struct_i_layout --> scm_vtable_index_layout

1859 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1861 * struct.c (scm_print_struct): Use new printer slot; Default
1862 printing: Also output hex code of vtable so that type identity
1863 will be indicated as well.
1864 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1865 Removed struct_printer_var; Removed struct-vtable-offset;
1866 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1867 vtable-offset-user): New constants.
1869 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.

1872 the type represented by this vtable.
1874 * print.c (scm_iprin1): Don't print arguments of macro
1875 transformers. (They are always: exp env.); Bugfix: Unmemoize
1876 transformer source with correct environment.
1878 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1880 Streamlining of call-with-dynamic-root:

1883 there is now only one catch.
1884 (cwdr_outer_body): Removed.
1885 (cwdr_handler): New function.
1886 (scm_internal_cwdr): New function to perform the function of cwdr
1887 but take args that are more useful to C code. Also, the handler
1888 is now invoked *outside* of the new dynamic root, like the docs
1889 say. We no longer have to catch absolutely all errors, the caller
1890 is responsible for using a handler that does not throw, if he
1892 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1893 * root.h (scm_internal_cwdr): New prototype.
1895 Even more but risky streamlining:
1897 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1898 allocation of the jumpbuf of a root continuation. The changes
1899 below are controlled by it. They are now deactivated.
1900 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1901 the JMPBUF of the scm_rootcont to NULL before returning.
1903 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1904 when they are non-NULL.
1905 (scm_gc_mark): Likewise, mark only when non-NULL.
1907 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1908 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1910 * gc.c (scm_done_malloc): New function.
1911 gc.h (scm_done_malloc): New prototype.
1913 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.

1920 a certain value is acceptable as a port argument.
1921 (scm_print_state_vtable): New variable.
1922 (scm_free_print_state): Set `revealed' field to false.
1923 (scm_iprin1): Call user supplied closure printer with
1924 scm_printer_apply. Print in the traditional way when there isn't
1925 one or when it returns #f.
1926 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1927 Accept a port/print-state pair in addition to just a port.
1928 (scm_prin1): Don't return the print_state to the pool when it has
1930 (scm_printer_apply): Set `revealed' field of print_state to true.
1931 (scm_init_print): Set scm_print_state_vtable.
1932 (print_state_fluid, print_state_fluid_num): Removed.
1934 * throw.h (scm_handle_by_proc_catching_all): New prototype
1935 throw.c (scm_handle_by_proc_catching_all): New function
1937 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1939 * Makefile.in: Regenerated with automake 1.2c.
1941 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1943 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1944 was looping endlessly.
1946 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1948 * strports.c (scm_eval_string): Don't close the port.
1950 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1951 former returns a nice normal integer. (Thanks to Daniel
1954 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1956 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1957 makefile variable as a build parameter called LIBS. The
1958 build-guile program will use this, for the time being.
1959 * Makefile.in: Regenerated.
1961 Thanks to Shiro Kawai:
1962 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1963 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1966 * Makefile.in: Regenerated with automake 1.2a.
1968 * script.c (scm_compile_shell_switches): If we hit the -c or --
1969 arguments, don't set the car of (command-line) to scm_usage_name,
1970 the prettified name of the guile executable; give it the full
1971 path, the way shells usually handle $0.
1973 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1975 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1976 Scheme-level name `array-map' and renamed `serial-array-map' to
1977 `serial-array-map!'.
1979 * backtrace.c: Introduced exception handlers which now enclose
1980 `display-error' and `display-backtrace' so that error reporting
1981 won't get into infinite loops if an error occurs during displaying
1982 of the error. This can very easily happen with user supplied
1983 print call-back routines.
1985 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1987 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1988 the names `serial-array-map' and `array-map' should be removed.)
1990 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1992 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1993 Added #include "objects.h"
1995 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1996 Add #include "feature.h".
1998 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1999 (modinclude_HEADERS): Added objects.h.
2001 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
2002 This test is needed at many places in the code and should be
2003 abstracted. (Motivated by the need of this test in libguiletk.)
2005 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
2006 (scm_eval_string), load.c (scm_primitive_load,
2007 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
2008 Use SCM_EOF_OBJECT_P.
2010 * eval.c (scm_init_eval): Add feature `delay'.
2012 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2014 * scmhob.h: Removed.
2016 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2018 * list.h (SCM_LISTn): New macros. Make list creation in C code
2019 prettier. The idea comes from STk.
2021 * sequences.h, sequences.c, append.h, append.c: Removed. These
2022 files implemented non-R4RS operations which would encourage
2023 non-portable programming style and less easy-to-read code.
2025 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
2028 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
2029 sequences.h, #include append.h.
2031 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
2034 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
2036 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
2038 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
2040 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2042 * eval.c: Added #include "objects.h"
2044 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
2047 * smob.c (scm_smob_prehistory): Create two objectsmobs with
2048 adjacent smob numbers.
2050 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2052 * procprop.h: Added declaration of scm_i_inner_name.
2054 * gsubr.c: New global symbol scm_i_inner_name.
2056 * debug.c (scm_procedure_name): Try procedure property
2057 `inner-name' if `name' fails.
2059 * print.c (scm_iprin1): Use scm_macro_name.
2061 * eval.c (scm_m_define): Give names to macros as well; Only the
2062 first top-level definition gives a procedure/macro a name.
2063 Otherwise confusing names can turn up in backtraces.
2064 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
2065 `name'; Give names to macros as well.
2067 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
2068 (scm_macro_transformer): Use SCM_CLOSUREP instead of
2071 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2073 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
2075 (prinmacro): Removed. The code has been moved/merged into print.c
2076 in order to decrease code redundancy. We want macros to print in
2077 a way equivalent to procedures, and it would be silly to duplicate
2078 the required code. (We don't want to maintain two places.)
2079 (macrosmob): Print field is now a NULL pointer.
2081 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
2082 scm_macro_transformer): New prototypes.
2083 (scm_tc16_macro): Declared.
2085 * print.c (scm_iprin1): Added code for printing of macros. Macros
2086 are now printed in a way equivalent to procedures.
2088 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
2090 * procs.h (scm_closure_p): Added declaration.
2092 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2094 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
2095 Shouldn't pass "heap" as the subr name.
2097 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
2099 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
2100 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
2101 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
2102 gh_equal_p): Use SCM_NFALSEP, instead of testing against
2103 SCM_BOOL_T. Any non-false value is true.
2105 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2107 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
2108 scm_gensym): Added prototypes.
2110 * symbols.c (scm_gensym): New function. This will speed up
2111 certain types of applications (such as macro systems) which
2112 generate lots of symbols.
2114 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2116 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
2118 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
2120 * unif.c (scm_shap2ra): tighten the checking of the array dimension
2121 specifier, since (2) or (2 . 3) would cause SEGV.
2122 (scm_transpose_array): more argument checking fixes.
2124 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
2126 * Makefile.in: Regenerated.
2128 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
2130 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
2132 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2134 * error.c, error.h (scm_error_callback): Removed (see NEWS).
2136 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
2138 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
2139 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
2142 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
2143 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
2144 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
2145 scm_array_p, scm_array_rank, scm_array_dimensions,
2146 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
2147 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
2148 scm_array_prototype): Added case scm_tc7_wvect.
2150 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
2152 * errno.h: prototype for scm_strerror.
2153 * error.c (scm_strerror): new procedure.
2155 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2157 * list.c (scm_list_append_x): Allow non-pair as last argument.
2158 This is consistent with the R4RS append and is probably the
2159 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
2161 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2163 * stime.h: prototype for scm_times.
2164 * stime.c (scm_times): new procedure.
2165 * ioext.c (scm_fseek): if the first argument is a file descriptor
2167 (scm_ftell): if the first argument is a file descriptor call lseek
2169 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
2170 * filesys.c (scm_chmod): if the first argument is a file descriptor,
2172 (scm_chown): if the first argument is a port or file descriptor,
2174 (scm_truncate_file): new procedure.
2175 Add DEFER/ALLOW INTS to a few other procedures.
2176 (scm_fsync): new procedure.
2177 (scm_open_fdes): new procedure.
2178 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
2180 (scm_fcntl): the first argument can now be a file descriptor. The
2181 third argument is now optional.
2183 * posix.c (scm_execl, scm_execlp): make the filename argument
2184 compulsory, since omitting it causes SEGV.
2185 (scm_sync): return unspecified instead of #f.
2186 (scm_execle): new procedure.
2187 (environ_list_to_c): new procedure.
2188 (scm_environ): use environ_list_to_c. disable interrupts.
2189 (scm_convert_exec_args): take pos and subr arguments and
2190 improve error checking.
2192 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2194 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
2195 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
2196 argument to SCM_ASSERT. Furthermore, the name of the function
2197 should be passed as first argument when signalling
2198 SCM_WNA. (Thanks to Thomas Morgan)
2200 * gsubr.c (scm_gsubr_apply): From Radey Shouman
2201 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
2202 dispatches on the number of actual args has a default case
2203 reporting an internal error. This is a vestige from a version
2204 that mallocated a SCM vector to hold the arguments. In the
2205 current version this check is too late: if it ever happens we will
2206 have already overstepped the bounds of the array.
2208 Also, the patch [...] adds a check for too many actual arguments."
2210 mdj: Removed check for "internal programming error".
2212 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2214 * gh_io.c (gh_write): New function.
2216 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
2217 throw.c (scm_internal_stack_catch): New sibling to the other catch
2218 functions. Code moved from gh_eval.c.
2219 throw.h: Added header.
2220 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
2221 scm_internal_stack_catch.
2223 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2225 * ioext.h: fix up prototypes.
2226 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
2227 Scheme name is now dup->fdes.
2228 (scm_dup_to_fdes): make the second argument optional and
2229 fold in the functionality of scm_primitive_dup.
2230 (scm_primitive_dup): deleted.
2232 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
2234 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
2235 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
2236 ultrix are defined. Use setvbuf instead of setbuf.
2237 (scm_setvbuf): new procedure.
2238 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
2239 (scm_setfileno): moved from ioext.c.
2240 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
2241 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.

2251 state as nested data while they are printed.
2252 (print_state_fluid, print_state_fluid_num): New variables.
2253 (scm_init_print): Initialize them.
2254 (scm_iprin): If print_state_fluid carries a print_state, use that
2255 instead of creating a new one.
2256 (scm_printer_apply, apply_stub, struct apply_data): New
2257 definitions to help with calling printer functions written in
2259 * print.h (scm_printer_apply): New prototype.
2261 * struct.c (scm_print_struct): Use scm_printer_apply to call the
2262 user defined struct printer.

2272 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
2273 SCM_ASSERT: arg comes before pos.
2275 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2277 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
2278 to a list of length zero correctly.
2280 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2282 Supply an `fgets' method for port objects to do fast line i/o.

2296 * ioext.h: removed scm_duplicate_port prototype.
2298 * ioext.c (scm_primitive_dup2): return the new file descriptor
2299 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
2301 (scm_fdopen): bug fix: don't try to make port unbuffered until its
2302 stream has been set.
2303 (scm_duplicate_port): deleted, there's now an implementation in
2305 (scm_primitive_dup2): do nothing if newfd == oldfd.
2307 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
2309 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the

2313 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
2315 * fluids.c (next_fluid_num): don't do
2316 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
2318 * ports.h: prototypes too.
2319 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
2321 * fports.h: prototype too.
2322 * fports.c (scm_evict_ports): moved from ioext.c.
2324 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>

2349 (scm_make_root): Call scm_copy_fluids to make fluid bindings
2350 unique for the new root when it has a parent.
2352 * smob.h: Include "libguile/print.h" to make scm_print_state

2356 data. (dynl_smob): Use it.
2357 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
2358 the dynamic object data below the linking of the object to avoid
2359 memory leak when the linking code throws an error. Now the code
2360 leaks a whole dynamically linked library when must_malloc throws,
2361 but that should be much less likely.
2363 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
2365 Changes to compile under gnu-win32, from Marcus Daniels:
2366 * stime.c (tzset): If tzset isn't provided, make it a NOP.
2367 (scm_localtime): Change SCM_EOF to SCM_EOL.
2368 (scm_mktime): Likewise.
2369 * socket.c: Don't include sys/un.h unless autoconf tells
2370 us Unix domain sockets are available.

2372 (scm_addr_vector): Likewise.
2373 (scm_init_addr_buffer): Likewise.

2381 (scm_setpwent): For setpwent.
2382 (scm_setegid): For setegid.
2383 * net_db.c (scm_inet_netof): Don't include unless support

2399 scm_misc_error, not SCM_EOF.
2401 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
2402 arguments for formatting the error message, not SCM_BOOL_F. I
2403 think this is left over from the (eq? '() #f) days.
2405 * read.c (recsexpr): Give this a dummy definition if
2406 DEBUG_EXTENSIONS isn't #defined.
2408 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
2410 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

2420 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
2421 alloca.lo will be included in @LIBLOBJS@. Something better than
2422 this should be possible.
2423 * Makefile.in: Regenerated.
2425 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2427 * simpos.h: prototype for scm_primitive_exit.
2428 * simpos.c (scm_primitive_exit): new procedure, terminates the
2429 process without unwinding the stack.
2431 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
2433 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
2434 argument and logior its components together, so the user doesn't
2435 have to do this explicitly. Also, if regexp/basic is supplied, then
2436 turn off REG_EXTENDED.
2437 (scm_init_regex_posix): New regexp/basic symbol.
2438 (REG_BASIC): #define this if it is not already present.
2440 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

2454 * Makefile.in: Regenerated.
2456 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
2457 flag; I don't think we support it.
2458 (scm_make_regexp): Make sure the user doesn't pass the
2461 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
2463 (scm_init_regex_posix): Define constants for the REG_mumble flags;
2464 name them according to the SCSH convention: regexp/mumble.

2471 Makefile directory variables. Print a message, but don't print
2473 (versiondat.h): Print a message, but don't print all the commands.
2474 * load.c: #include "alist.h".
2475 (init_build_info): New function.
2476 (scm_init_load): Call it.
2477 * Makefile.in: Regenerated.
2479 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
2481 * root.c: Establish a reliable catch-all handler for the new root.
2482 After all the Scheme handler function might signal an error too,
2483 and we don't want to lose that.
2484 (cwdr_inner_body): Renamed from cwdr_body.
2485 (cwdr_outer_body): New function, to establish the user's handler,
2486 and pass control to cwdr_inner_body.
2487 (cwdr): Establish the reliable catch-all handler here, and pass
2488 control to cwdr_outer_body.
2489 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
2490 the user's handler through to cwdr_outer_body.
2491 * throw.c (scm_handle_by_message): Move guts into....
2492 (handler_message): New static function.
2493 (scm_handle_by_message_noexit): New function.
2494 * throw.h (scm_handle_by_message_noexit): New prototype.
2496 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
2497 across this. Only works on GCC. Otherwise, we hope for the best.
2498 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2499 the feeling that real thread systems will not need this...
2501 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2503 Try to detect when people are using one version of libguile and a
2504 different version of ice-9. People have been skewing things and
2505 sending in bug reports.
2506 * Makefile.am (versiondat.h): New file to generate.
2507 * version.c: #include "versiondat.h", to get version info.
2508 (scm_libguile_config_stamp): New function.
2509 * script.c: #include "version.h".
2510 (scm_compile_switches): Call scm_version to get version number.
2511 * scmconfig.h.in, Makefile.in: Regenerated.
2512 * Makefile.in: Regenerated.
2514 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
2515 primitive definitions under their Scheme names.
2517 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2518 1:2. Helps avoid confusion between installed and uninstalled libs.
2520 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2523 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2524 backslash from definition; this should be used like: GDB_INTERFACE;
2526 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2528 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
2529 new port unbuffered until its stream has been set.
2531 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2533 * ports.h: new prototype.
2534 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
2536 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
2538 Make things compile neatly under Sun's C compiler.
2539 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
2540 * extchrs.c (xmbtowc): Make the second arg a normal char, not
2541 unsigned, because that's what the ANSI function takes.
2542 * extchrs.h (xmbtowc): Corresponding change to prototype.
2543 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2545 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2546 argument plain char *.
2547 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2549 * tag.c (scm_tag): Remove unreachable statement.
2550 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2551 top of the word, it should be unsigned.
2553 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2554 is defined, to avoid warnings; it's only used in the
2555 conflict-checking code. Which might go away anyway.
2556 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2557 conditionals; put the label definition in an #if too, to stifle
2560 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2561 ChangeLog-threads in the distribution.
2562 * Makefile.in: Regenerated.
2564 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2566 * guile-snarf.in: Changed regexp to support CPPs that insert
2567 whitespace between lexical tokens (which munges the `%%%' snarf
2570 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2572 * load.c (scm_init_load_path): Append $(datadir)/guile to
2573 %load-path, so modules do not have to be installed in Guile's
2574 current version directory.
2576 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2578 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2579 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2580 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2581 call the sysdep functions with deferred ints.
2582 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2583 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2584 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2587 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2590 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2592 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2594 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2596 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2599 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2601 * eval.c (scm_lookupcar1): New procedure to cope with a race
2602 condition during lookup (when using threads).
2603 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2604 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2607 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2609 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2610 supplied. (Change from Tim Pierce.)
2612 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2614 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2615 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2616 default and not `()'. `#f' is the canonical non-value in Scheme,
2619 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2621 * struct.c (struct_printer): New variable that holds a handle on
2622 the Scheme variable *struct-printer*. This variable can be set by
2623 Scheme code to override the printing of structures.
2624 (scm_print_struct): If struct_printer is set, call it. If it is
2625 not set, or returns #f, print the structure in the old fashion.
2626 Include "eval.h" for scm_apply.
2628 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2630 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2631 scm_struct_i_n_words to get the number of fields, not
2632 -scm_struct_n_extra_words.
2634 On the route to fancier struct printing:
2635 * struct.c (scm_print_struct): New function to print a structure.
2636 Include "genio.h" to support it. This function doesn't do
2637 anything interesting right now, but I think it should be here
2639 * struct.h: Include "print.h" and add prototype for
2641 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2642 print structures ourself.
2644 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2646 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2647 before applying the handler in case it doesn't return.
2649 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2651 * scmsigs.h, async.h: updated.
2653 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2656 * posix.c (scm_uname): interpret only negative values as an error.
2657 Solaris normally returns a positive value.
2659 * script.c (scm_compile_shell_switches): if we are not going into
2660 an interactive repl, set scm_mask_ints to zero so that asyncs can
2663 * simpos.c (scm_system): don't ignore/unignore signals around
2666 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2669 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2670 done in boot-9.scm instead.
2672 * scmsigs.c, async.c: Major rewriting of signal handling code.
2673 (scm_sigaction): new procedure.
2674 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2676 (scm_raise): return unspecified, throw error on failure.
2678 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2680 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2681 feature, to help boot-9.scm decide whether to import the regex
2684 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2686 * eval.c: Include scmconfig.h at the beginning of the file so that
2687 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2690 * regex-posix.c: #include "_scm.h" before conditionally #including
2691 <regex.h>; the former defines HAVE_REGCOMP.
2693 * regex-posix.c: #include <regex.h> conditionally, so the file is
2694 CPP'able (for dependency scanning) even on systems that don't have
2697 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2699 Add new R4RS-compliant syntax for keywords.
2700 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2701 regardless of the setting of the `keywords' read option.
2702 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2703 can be re-read no matter what the setting of the `keywords' read
2706 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2708 Add support for POSIX regular expressions.
2710 * regex-posix.c, regex-posix.h: New files. (Some code
2711 is taken liberally from rx/rgx.c in the old Guile dist.)
2713 * init.c: Include regex-posix.h.
2714 (scm_boot_guile_1): Call scm_init_regex_posix.
2716 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2717 Add regex-posix.[ch] sources.
2718 * Makefile.in: Regenerated.
2720 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2721 to do this automatically? It didn't for me, bleh.)
2723 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2725 * fports.c (print_pipe_port): New function.
2726 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2727 latter doesn't even take the right arguments.
2729 * Makefile.am: Increment shared lib revision number. I think
2730 sometimes the uninstalled Guile finds the installed shared lib;
2731 Gord says doing this might help. As things turned out, I can't
2732 say whether it does.
2733 * Makefile.in: Regenerated.
2735 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2736 passing it as the closure argument to scm_boot_guile. (Bill
2739 * ports.c (print_void_port, putc_void_port, puts_void_port,
2740 write_void_port, flush_void_port, getc_void_port, close_void_port,
2741 noop0): Use ANSI prototypes instead of K&R declarations, so the
2742 initialization of void_port_ptob gets aggressively type-checked.
2743 Fix arguments of print_void_port and write_void_port. (Bill

2777 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2779 * script.c (scm_find_executable): Use prototype-style definition
2780 here; apparently it's not quite right to have const in a prototype
2781 and then use a K&R declaration. I wonder if stuff like this will
2782 go away if we compile with -Wrequire-prototypes, or whatever that
2783 is... (Bernard URBAN)
2785 * scmhob.h: New text from Bernard URBAN.
2787 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2789 * script.c: Don't #define const on hpux. Configure takes care of
2790 this. (Thanks to Larry Schwimmer.)
2792 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2793 decide whether to #include <unistd.h>, instead of listing a bunch
2794 of systems. Don't #include stdio twice. Removed dyked-out
2795 definition of scm_find_impl_file.
2797 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2799 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2800 library version info to 1:0.
2801 * Makefile.in: Regenerated.
2803 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

2807 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2808 throw.c: Update copyright years; these files have been worked on
2809 significantly in 1997, but only had copyright years for 1996.
2810 Also, change name of copyright holder on some from Mikael
2811 Djurfeldt to Free Software Foundation; he has signed papers
2812 assigning the changes to the FSF.
2814 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2815 reason not to give the user the option.
2817 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2818 Return #f on end-of-file when scanning table (i.e. when called
2819 with no arguments). Try to catch errors, when we can.
2820 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2822 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2823 external declarations. These are useful.
2825 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2827 * posix.c: don't include <sys/select.h> or define macros for
2828 select, since they were not used in this file.
2830 * filesys.c (scm_select): make the fifth parameter microseconds,
2831 not milliseconds. let the fourth parameter be either a real value
2832 or an integer or #f. The first, second and third arguments can
2833 now be vectors: the type of the corresponding return set will be
2835 (set_element, get_element): new static procedures.
2837 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2839 * strports.c (scm_eval_string): New function.
2840 (scm_eval_0str): Trivially re-implemented in terms of
2842 * strports.h (scm_eval_string): New extern decl.
2844 * net_db.c (h_errno): Add extern decl for this.
2846 * fports.c (local_pclose): New function.
2847 (scm_pipob): Use it in the initializer here.
2850 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2851 Use a meaningful error message when signalling an error. For
2852 this, scm_gethost must check h_errno rather than errno.
2854 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2856 * Makefile.in: Regenerated, using automake-1.1p.
2858 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2860 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2861 not SCM_UNSPECIFIED.
2863 * script.c (scm_compile_shell_switches): don't append (quit) if
2865 (scm_shell): call scm_exit_status and exit on the result of the
2868 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2870 Ensure that shared substrings are handled properly when passed to
2871 a system call or other foreign function. Many thanks to Tim
2873 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2874 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2875 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2876 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

2888 SCM_COERCE_SUBSTR to make sure shared substrings are
2891 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2893 * error.c (scm_error): Add newline to error message.
2895 * init.c (scm_init_standard_ports): Doc fix.
2897 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2899 * dynl-shl.c: Completely replaced with new code from Bernard
2902 * script.c (scm_ice_9_already_loaded): New variable.
2903 (scm_compile_shell_switches): Use it.
2905 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2907 * filesys.c (scm_input_waiting_p): add missing third argument to

2911 calling gmtime in case they share a buffer.
2912 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2915 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2917 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2919 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2921 * Makefile.am (check-local): New target, which causes 'make check'
2922 to run gh_test_c and gh_test_repl, with some trivial input.
2923 * Makefile.in: Rgnrtd.
2925 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2927 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2930 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2932 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2933 sure how this was supposed to work.
2934 (scm_async_click): don't send SCM_TICK_SIGNAL.
2935 (scm_init_async): don't initialize %tick-thunk.
2937 * the following change doesn't affect the Scheme interface:
2938 gc-thunk is called at the end of garbage collection. however it's
2939 no longer implemented by pretending it's a signal.
2941 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2942 system async corresponding to scm_gc_thunk.
2943 * async.h: declare scm_gc_async.
2944 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2945 gc-thunk directly, instead of going through a signal handler.
2946 (scm_gc_async): new variable, points to the GC system-async.
2947 (scm_init_async): save the GC async as scm_gc_async instead
2948 of using system_signal_asyncs.
2949 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2951 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2953 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2954 Don't screw up if we're interrupted.
2955 * Makefile.in: Regeneradet.
2957 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2959 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2961 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2962 we're not using AM_INIT_GUILE_MODULE any more.
2963 * Makefile.in: Reneregated.
2965 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2967 Functions for finding variable bindings, grace à Tim Pierce.
2968 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2969 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2971 Get 'make dist' to work again.
2972 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2973 * Makefile.in: Regenerated, like a surry without a fringe on top.
2975 Changes for reduced Guile distribution: one configure script,
2977 * configure.in, configure: Removed.
2978 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2979 real configure script lives.
2980 * Makefile.in, scmconfig.h.in: Regenerated.
2982 * init.c: #include "script.h", to get prototype for script.c's
2985 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2987 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2988 scm_must_malloc, not raw malloc.
2990 * script.c (scm_compile_shell_switches): Dyke out debugging output
2993 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2995 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2997 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2998 system has them. Hope this is safe. Previously
2999 sys/timeb.h was included if HAVE_FTIME was defined or if
3000 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
3001 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
3003 * ioext.c (scm_setfileno): add missing third argument to
3004 scm_misc_error call.
3006 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
3008 * eq.c (scm_equal_p): Correctly compare strings of different
3009 varieties. (Thanks to Tim Pierce.)
3011 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
3013 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
3014 #! block comment must occur on a line all by itself.
3016 Move most of the guts of shell command processing into libguile,
3017 so guile.c can be very small (and eventuallly auto-generated. (I
3018 mean, generated mechanically, not self-generated. Hmm.))
3019 * guile.c, script.c, script.h: New source files.
3020 * init.c (scm_boot_guile_1): Call scm_init_script.
3021 * libguile.h: #include "script.h".
3022 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
3023 targets, for new executable.
3024 (libguile_la_SOURCES): Mention script.c.
3025 (modinclude_HEADERS): Add script.h.
3026 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
3027 not dynamic linking is enabled. This is because we're generating
3028 executables now. Move CY_AC_WITH_THREADS call after those, so the
3029 values of cy_cv_threads_libs captures the libs chosen above.
3030 * Makefile.in, configure, aclocal.m4: Regenerated.
3032 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
3033 We don't maintain this interface any more, and it just confuses
3036 * alloca.c: #include <scmconfig.h>, not <config.h>.
3037 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
3038 it'll get included in disties.
3040 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
3042 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
3043 be distributed, because they confuse people.
3044 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
3046 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
3048 * configure.in: check for presence of gethostent (not present on
3049 OpenBSD by default).
3050 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
3051 * configure, scmconfig.h.in: Regenerated.
3053 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
3055 * backtrace.c (scm_backtrace): Split message string across
3056 newlines properly. GCC is more tolerant of this than other
3059 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
3061 Merge threads directory into libguile.
3062 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
3063 threads.h: New source files.

3065 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
3067 (modinclude_HEADERS): Add threads.h, coop-defs.h.
3068 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
3069 coop-threads.c.cygnus, coop-threads.h.cygnus.
3070 * configure.in: If we're using threads, include threads.o in
3072 * _scm.h, libguile.h: threads.h lives in this directory now.
3073 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
3074 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
3075 currently used, but brought along for information's sake.
3076 * ChangeLog-threads: log from old 'threads' directory.
3077 * Makefile.in, configure: Rebuilt.
3079 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
3081 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
3084 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
3086 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
3088 Merge GH interface library into libguile.
3089 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
3090 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
3091 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
3092 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
3094 (EXTRA_libguile_la_SOURCES): ... here.
3095 (pkginclude_HEADERS): Add variable, to get gh.h installed.
3096 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
3097 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
3098 New variables, describing how to build the gh test programs.
3099 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
3100 build the test programs, and we probably should have been linking
3101 libguile.la against them all along, to support AIX shared libs.
3102 Add cflags for threads to CFLAGS; add libs for threads to new
3103 variable THREAD_LIBS, used in Makefile.am.
3104 * ChangeLog-gh: log from old `gh' subdirectory.
3105 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
3107 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
3109 * acconfig.h: Undo change of Apr 9; including the definition of
3110 PACKAGE in the guile headers conflicts with applications' own
3112 * scmconfig.h.in: Regenerated.
3114 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

3121 when PROC is receiving no arguments.
3123 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
3125 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
3126 have S_IFSOCK. This is the case under Ultrix.
3128 * posix.c (scm_status_exit_val, scm_status_exit_val,
3129 scm_status_term_sig, scm_status_stop_sig): Modified to work with
3130 Ultrix versions of WIFSTOPPED, etc., which assume that their
3131 arguments are lvalues (hmm).
3133 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
3135 * eval.c: Doc fixes.
3137 * throw.c: Doc fixes; rearranged.
3139 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
3141 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
3143 * acconfig.h: Added entry for PACKAGE.
3144 * scmconfig.h.in: Regenerated.
3146 Changes to work with automake-1.1n, which has better libtool support.
3147 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
3148 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
3150 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
3152 * Makefile.in: Rebuild.
3154 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3156 * stime.c (scm_mktime): take an optional zone argument.
3157 (scm_localtime): check putenv return value.
3158 (scm_strftime, scm_strptime): moved from posix.c. move #include
3160 stime.h, posix.h: update prototypes.
3161 (bdtime2c, setzone, restorezone): new static procedures.
3162 (scm_mktime, scm_strftime): use them.
3163 (scm_strftime): don't call mktime before strftime. Use
3164 filltime for return value.
3165 (filltime): convert NULL zname to #f.
3166 (scm_strptime): return a count of characters consumed, not
3167 the remaining string.
3169 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3171 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
3172 (scm_mktime): likewise.
3174 Uncomment localtime and mktime.
3176 * configure.in: add AC_STRUCT_TIMEZONE.
3178 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3180 * stime.c (scm_init_stime): don't define ticks/sec.
3181 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
3182 return value problem and is still portable.)
3184 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3186 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
3187 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
3188 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
3189 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
3190 cpp_err_symbols.c): Corresponding changes.
3191 * Makefile.in: Regenerated.
3193 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3195 * posix.c (scm_putenv): don't check HAVE_PUTENV.
3196 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
3197 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
3198 * putenv.c: new file, from sh-utils 1.12.
3200 * posix.c (scm_environ): use malloc in place of scm_must_malloc
3201 since allocation isn't for Scheme objects.
3202 (scm_putenv): copy strings before placing in the environment.
3204 * stime.c (scm_current_time): throw an error if time returns -1,
3205 instead of returning #f.
3206 (scm_get_internal_real_time, scm_get_internal_real_time): use
3207 scm_long2num for return value instead of SCM_MAKINUM.
3209 * stime.h: prototypes updated.
3211 * stime.c (scm_time_in_msec): apparently unused, deleted.
3213 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
3215 * configure.in: check for gettimeofday.
3217 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
3218 which may be more usefully portable than a gettimeofday interface.
3220 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
3222 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
3224 * Makefile.in: Regenerated.
3226 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3228 * stime.c (filltime): recovered static procedure.
3229 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
3232 * posix.h: add prototype for scm_close_pipe, remove prototypes for
3233 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
3235 * posix.c (scm_mknod): split the mode argument into type and perms
3236 arguments, like the extra fields returned by stat.
3238 * fports.c (scm_pipob): set the close, free and print procedures.
3239 (scm_close_pipe): new procedure.
3241 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
3242 define them in boot-9.scm
3244 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3246 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
3247 wan't defined. Don't include fd.h.
3249 * Previously fd.h was regenerated whenever configure was run,
3250 forcing a couple of files to be recompiled.
3252 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
3253 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
3254 Check for _fileno as well as _file.
3256 * ioext.c: don't fd.h.
3257 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
3260 * Change the stratigy for getting information about errno
3261 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
3262 generating lists of symbols during the build process, which will
3263 not always work, include comprehensive lists in the distribution.
3264 To help keep the lists up to date, the "check_signals" and
3265 "check_errnos" make targets can be used.
3267 * configure.in: don't check for a command to extract errno codes.
3268 * Makefile.am: update file lists, remove errnos.list and errnos.c
3269 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
3270 check_errnos targets.
3271 (CLEANFILES): remove errnos.c and errnos.list, add
3272 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
3273 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
3274 * errnos.default: deleted.
3275 * cpp_signal.c: new file.
3276 * cpp_errno.c: renamed from errnos_get.c.
3277 * cpp_err_symbols, cpp_sig_symbols: new files.
3278 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
3279 * error.c (scm_init_error): #include cpp_err_symbols instead of
3281 * posix.c (scm_init_posix): don't intern signal symbols. #include
3284 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
3286 * strop.c (scm_i_index): allow the lower bound to be equal to the
3287 length of the string, so a null string doesn't always give an error.
3289 * posix.h: new prototypes.
3290 * posix.c (scm_status_exit_val, scm_status_term_sig,
3291 scm_status_stop_sig): new functions, as in scsh. They break down
3292 process status values as returned by waitpid.
3294 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
3296 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
3297 configure doesn't know about it.
3299 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3301 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
3303 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
3304 which defines C variables with global linkage.
3306 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3308 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
3311 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
3313 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
3314 has time to check why this doesn't work well with continuations.
3316 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
3318 * Fix shell syntax error; some shells won't tolerate
3319 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
3321 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3323 * posix.c (scm_uname): throw an error if uname fails instead
3326 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
3328 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
3331 * async.c (scm_ints_disabled): definition moved from error.c.
3333 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3335 * acconfig.h: Removed PACKAGE.
3337 * scmconfig.h.in: Regenerated.
3339 * snarf.h: g++ says it's non-portable not to specify the first
3340 argument in a varargs declaration. I introduced the first
3341 argument by using preprocessor conditionals.
3343 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
3345 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
3346 (scm_freopen): use RO string macros for filename and modes.
3347 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
3349 * posix.c (scm_getgrgid): simplify conversion of name to C string.
3350 (scm_mknod): use RO string macros for path.
3352 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
3353 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
3355 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
3356 use SCM_ROSTRINGP and SCM_ROCHARS.
3358 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3360 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
3363 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
3364 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
3365 support for byte vectors.
3367 * print.c (scm_iprin1): Limit number of vector elements printed
3368 according to pstate->length.
3370 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3372 * backtrace.c (scm_display_error_message): don't segv if message
3375 * error.h: prototype for scm_error_scm.
3377 * error.c (scm_error_scm): new procedure, reimplements scm-error
3378 in C and uses scm_error.
3380 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3382 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
3383 pointer to the Scheme variable read-hash-procedures and intern it
3384 in scm_init_read. Modify scm_read_hash_extend and
3385 scm_get_hash_procedure to use the pointer.
3387 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3389 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
3390 (SCM_KEYWORD_STYLE): defined.
3392 * read.c (scm_read_opts): add a keywords option. This isn't a
3393 boolean option, in case someone wants to add support for DSSSL
3395 Setup scm_keyword_prefix symbol.
3396 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
3398 I've left keyword support disabled by default, since it doesn't
3399 seem to break the module system and it gives R4RS standard behaviour.
3400 It can be reactivated with (read-set! keywords 'prefix).
3402 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3404 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
3405 before constructing arbiter.
3407 * eval.c (scm_m_define): Bugfix: Check that the object is a
3408 closure before setting the procedure property!
3410 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
3412 * ports.c: Removed `ungetc-char-ready?'.
3414 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
3416 * read.c (scm_init_read): intitialise scm_read_hash_procedures
3417 (idea from Mikael: make it a pair so scm_permanent object only
3419 (scm_read_hash_extend): don't call scm_permanent_object.
3420 (ideas from Mikael): if chr is already in the list, replace its
3421 procedure instead of appending it again. If proc is #f, remove
3423 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
3425 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
3427 * gdbint.c (gdb_read): update scm_lreadr usage.
3429 * load.h: update prototypes.
3431 * load.c (scm_primitive_load, scm_read_and_eval_x,
3432 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
3434 * read.h: add prototype for scm_read_hash_extend. Change args for
3437 * read.c (scm_read_hash_procedures): new variable.
3438 (scm_read_hash_extend): new procedure.
3439 (scm_get_hash_procedure): new procedure.
3440 (scm_lreadr): use scm_get_hash_procedure instead of an argument
3441 for extended # processing.
3442 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
3443 scm_read_token): remove case_i, sharp arguments. Change callers.
3445 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
3447 * read.h (SCM_N_READ_OPTIONS): increase to 3.
3448 (SCM_CASE_INSENSITIVE_P): define.
3450 * read.c: add case-insensitive option to scm_read_opts.
3451 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
3452 to determine whether to convert symbol case.
3453 (default_case_i): definition removed.
3454 * read.c (scm_read_token): if case_i, downcase ic before doing
3457 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3459 * configure.in: Added configuration option `guile-debug'.
3460 Configure with --enable-guile-debug if you want a bunch of extra
3461 functions used for debugging when developing Guile.
3463 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3465 * procs.c (make-cclo): New undocumented debugging procedure: Make
3466 compiled closure with internal procedure PROC and length LENGTH.
3467 Only compiled if GUILE_DEBUG is defined.
3469 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3471 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3473 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3475 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3476 with 3 or more args internally to the evaluator.
3478 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3480 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3481 with 3 or more args internally to the evaluator. This is mainly
3482 because we don't want to pass entry and exit points of the
3483 debug support twice, but it also seems to increase the speed of
3484 the evaluator for such calls (e. g. (+ 1 2 3)).
3486 * backtrace.c (scm_display_application): New procedure:
3487 display-application; Set fancy printing parameters individually
3488 for different types of display (backtrace, error, application).
3489 (These should of course be customizable!)
3491 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3492 clear the CHECK-flags.
3494 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3496 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3498 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3500 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3501 from pairs with a GLOC in the car.
3503 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3504 otherwise `symbol-hash' will behave badly.
3505 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3506 we get segmentation fault!
3508 * symbols.c: Added #include "weaks.h". New functions:
3509 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3510 moved to an extraneous library when we split libguile.)
3512 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3514 * filesys.c (scm_stat): stat now takes fport arguments too as
3515 documented in the manual.
3517 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3519 * debug.c (scm_single_step): Bugfix: Call continuation with
3520 scm_call_continuation instead of throwing to it.
3522 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3524 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3525 argument wasn't declared to be optional.
3527 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3529 * stime.c (scm_init_stime): Add feature "current-time".
3531 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3533 * throw.h: prototype for scm_exit_status.
3534 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3535 args to derive an exit status. Allows (quit) to work from a
3537 (scm_exit_status): new function.
3540 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3542 * eval.c (scm_deval): Removed some old code.
3543 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3545 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3548 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3551 * procs.c: Introduce the existent C function scm_thunk_p at the
3552 Scheme level as well.
3554 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3556 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3557 used from C to easily lookup the value of a symbol in the current
3560 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3562 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3563 scm_init_unif in this file. This will also fix a previous problem
3566 * configure.in: Added AM_MAINTAINER_MODE
3568 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3570 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3573 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3575 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3576 source files that are not always included in libguile but should
3577 have their dependencies calculated by automake. This variable is
3578 recognized by automake, no further magic is needed.
3579 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3580 to deal exclusively with *.lo files, as it seems. The *.o files
3581 are built automatically when the corresponding *.lo file gets
3584 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3586 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3589 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3591 * unif.c (scm_array_set_x): minor change to argument error checking.
3593 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3595 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3596 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3597 They should only be included in the library at configure.in's
3599 (libguile_la_LDADD): Include the appropriate .lo files here.
3600 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3601 so we know when to build them (and their .lo bretheren).
3602 * configure.in (LIBLOBJS): New substituted variable. We let
3603 configure decide which .o files to include in LIBOBJS, and then
3604 put the corresponding list of .lo files in LIBLOBJS. The latter
3605 is what we pass to libtool.
3606 * Makefile.in, configure: regenerated.
3608 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3610 * symbols.c (scm_sysintern0): New function. Contains the core of
3611 old scm_sysintern but doesn't take a second value argument.
3612 (scm_sysintern): Now uses scm_sysintern0.
3613 (scm_sysintern_no_module_lookup): Renamed to
3614 scm_sysintern0_no_module_lookup and doesn't take a second value
3615 argument any longer.
3617 * symbols.h (scm_sysintern0: Added declaration.
3619 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3620 scm_sysintern when interning option keys. Otherwise we risk
3621 destroying the values of already interned variables.
3623 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3624 scheme-level boolean (use SCM_NFALSEP).
3626 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3628 (scm_backtrace): New function. (C version of old function from
3629 boot-9.scm) Motivation: Make it possible to display backtraces
3630 without depending on boot-9.scm. (I'm uncertain if this
3631 motivation is good enough...)
3633 * root.h (scm_root_state): Add member the_last_stack_var.
3634 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3636 * root.c (mark_root): Mark scm_the_last_stack_var.
3638 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3641 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3643 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3644 1. mark_lazy_catch didn't mark the smob.
3645 2. Both functions above have standard variants:
3646 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3647 free_lazy_catch --> scm_free0.
3649 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3651 * throw.c (scm_internal_lazy_catch): New function.
3652 (scm_lazy_catch): Rewritten to use it.
3653 (scm_ithrow): Handle the new lazy catch representation.
3654 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3655 that doesn't have a jmpbuf is a lazy catch clause.
3656 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3657 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3658 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3660 (scm_init_throw): Register the new lazy-catch smob type.
3661 * throw.h (scm_internal_lazy_catch): decl for new function.
3663 * throw.c (scm_internal_catch): Doc fixes.
3665 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3666 configure.in. Including this might cause problems if applications
3667 that link against libguile include their own copies of alloca, but
3668 if they're using autoconf, they should be adding libguile to LIBS
3669 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3670 the copy in libguile, and things will be okay. (I think.)
3672 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3674 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3676 strop.h: move prototypes too.
3678 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3680 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3683 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3684 etc. I deleted them from filesys.c long ago, but didn't
3685 notice they were here too (although ineffective since
3686 sys/stat.h wasn't included).
3688 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3690 * eval.c: Don't define alloca in GCC case. gcc will automatically
3691 use __builtin_alloca if appropriate.
3693 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3695 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3696 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3697 that values of automatic variables are preserved. See comments
3698 for safe_setjmp for details.
3700 Change from Thomas Morgan:
3701 * variable.c: Include eq.h.
3702 (var_equal): New function.
3703 (variable_smob): Use var_equal as the discriminator for variables.
3705 * throw.c (s_throw): Remove extraneous declaration.
3707 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3708 * eval.c: Add necessary CPP cruft to support that.
3709 * configure, Makefile.in, scmconfig.h.in: regenerated.
3711 Change from Thomas Morgan:
3712 * procprop.c (scm_procedure_properties): Convert the Scheme
3713 boolean returned by scm_procedure_p into a C boolean before using
3714 it as a condition for SCM_ASSERT.
3715 (scm_procedure_property): Likewise.
3717 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3718 indications of Unixness.
3721 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3723 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3725 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3727 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3728 "unknown # object" error messages.
3730 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3731 (scm_i_index) and declare it static. Add a 'direction' argument
3732 to indicate what way the search should go.
3733 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3735 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3736 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3738 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3740 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3742 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3743 to avoid clash with various scsh forks.
3745 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3747 The following two changes (ramap.c, throw.c) are motivated by the
3748 apparent unportability of forward declarations of static arrays of
3749 the form `static foo bar[];'.
3751 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3752 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3754 * throw.c (scm_throw): Moved above scm_ithrow.
3756 * options.h: Removed the extern declarations of scm_yes_sym and
3757 scm_no_sym since these are static.
3759 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3761 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3763 * Makefile.am: remove AWK=@AWK@.
3764 Add a rule for generating errnos.list.
3765 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3767 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3768 don't extract errnos, just set a variable (avoids the
3769 need to recompile error.c just because configure is run.)
3771 * unif.h: update prototypes.
3772 * unif.c (scm_uniform_array_read,write): change the offset and
3773 length arguments to start and end, for consistency.
3775 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3777 * ioext.h: update prototypes.
3778 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3779 scm_read_line_x, it's a more general procedure using an
3780 interface from scsh. read-line and read-line! are now defined
3782 Note that the new read-line trims the terminator
3783 by default, previously it was appended to the returned string. An
3784 optional argument specifies how to process the terminator (scsh
3785 compatible). For the old behaviour: (read-line port 'concat).
3786 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3787 returns a pair, but is converted to multiple values if the scsh
3790 socket.h: update prototypes.
3791 * socket.c (scm_recvfrom): for consistency with other procedures,
3792 take start and end as separate optional arguments.
3793 (scm_recv, scm_recvfrom): don't allow the second argument
3794 to be a size, only a buffer. Change the scheme names to
3795 recv! and recvfrom!. Don't return the buffer.
3797 * ioext.h, posix.h: move prototypes too.
3798 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3799 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3800 "read.h" and "unif.h".
3801 * ioext.c: include "chars.h"
3803 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3805 * dynl.c: The dynamic linking and module registration functions
3806 are now defined even when dynamic linking is not available for the
3807 host system. Some of their functionality can be done without
3808 dynamic linking; when it's really needed, they throw errors.
3810 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3812 * configure.in: Only define DYNAMIC_LINKING when one of the system
3813 dependent functions is detected.
3814 * dynl.c (scm_dynamic_func): New function to get the address of a
3815 function in a dynamic object.
3816 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3817 produced by scm_dynamic_func as the thing to call.
3819 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3821 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3822 (scm_register_module_xxx, scm_registered_modules,
3823 scm_clear_registered_modules): New functions.
3825 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3827 * symbols.c (scm_sysintern): Renamed to
3828 scm_sysintern_no_module_lookup.
3829 (scm_sysintern): New function to take the place of the old
3830 scm_sysintern. It uses the current toplevel lookup closure to give
3831 the symbol its value. This is a temporary hack to put packages
3832 like gtcltk into their own module.
3833 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3834 us whether `scm_top_level_lookup_closure_var' has been initialized
3836 * eval.c (scm_init_eval): Set it.
3838 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3840 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3841 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3843 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3845 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3846 scm_sys_dup): deleted: FD capability will be added to other
3848 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3849 scm_fd_free, fd_smob, scm_intern_fd.
3850 (scm_open): renamed from scm_sys_open. Return a port instead of
3851 an FD object. Make the mode argument optional.
3852 (scm_sys_create): deleted, it's just a special case of open.
3853 (scm_init_filesys): move interning of constants O_CREAT etc.,
3854 here (were previously using SCM_CONST_LONG macro).
3855 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3857 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3858 include "fports.h" and <stdio.h>
3859 (scm_stat, scm_select): don't support FD objects.
3861 * error.h: adjust scm_syserror_msg prototype.
3862 * error.c (scm_syserror_msg): take an extra argument for errno.
3863 Using the global value didn't always work, since it could be
3864 reset by procedure calls in the message or args arguments.
3866 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3867 I don't understand why the check was there (and what about the
3870 * strop.c (scm_string_copy): allow shared substrings to be copied.
3872 * unif.h: corresponding change to prototypes.
3873 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3874 recognize two new optional arguments: offset and length. Allow
3875 the port argument to be an integer (file descriptor, for scsh).
3876 Include <unistd.h> for "read" prototype.
3878 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3880 * socket.c: don't include filesys.h.
3882 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3884 * Makefile.am: add AWK=@AWK@ (?)
3886 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3888 Add a rule to generate errnos.c from errnos.
3889 * error.c (scm_init_error): include errnos.c.
3890 * errnos_cnvt.awk: new file, converts the list of errno codes to
3892 * errnos_get.c: new file.
3893 * errnos.default: new file, contains errnos to try if they can't
3894 be extracted from errno.h.
3895 * configure.in: if using GCC, try and extract errno codes from
3899 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3901 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3902 * Makefile.am: Made libguile into a libtool library.
3903 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3904 Set libtool_libs to indicate that libguile is a libtool library.
3905 See guile/ChangeLog for details.
3906 * .cvsignore: ignore "*.lo", the libtool library objects.
3908 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3910 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3911 use htons in getservbyport argument.
3913 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3915 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3916 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3919 * objprop.c (scm_object_property): No need to take the CDR of the
3920 value returned by scm_object_properties, since Aug 20 change.
3922 * configure.in: When checking for struct linger, #include
3923 <sys/types.h> as well as <sys/socket.h>. I've never known
3924 <sys/types.h> to cause any portability problems, and Solaris's
3925 <sys/socket.h> needs it.
3926 * configure: Rebuilt.
3928 I think the Sun compiler has chosen a perverse way to interpret
3929 ANSI declarations combined with K&R definitions. We'll
3930 appease it a little bit. But when it invades France, we fight.
3931 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3932 * print.h (scm_iprlist): Here too.
3933 * numbers.c (scm_divbigdig): Change definition to match
3934 declaration in numbers.h.
3935 * unif.c (scm_makflo): Change definition to match declaration in
3938 * init.c (scm_boot_guile): Don't return the value of
3939 scm_boot_guile_1. This function doesn't return a value;
3940 scm_boot_guile_1 doesn't return a value (or return at all).
3942 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3945 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3946 compile. I have a feeling this function is a bad idea anyway ---
3947 one should always test for features, not systems.
3949 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3950 semicolons. Only pure luck kept this from being noticed earlier.
3952 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3954 * socket.c (scm_recvfrom): Added missing semicolon.
3956 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3958 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3959 the buffer and start and end positions for scsh networking
3962 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3964 * configure.in: Revert previous change to this file; the problem
3965 is due to transient automake weirdness.
3966 * configure: Rebuilt.
3968 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3969 PLUGIN/guile.libs. configure generates the latter from the former.
3970 * Makefile.in: Rebuilt.
3972 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3973 need this if we install scripts, like guile-snarf.
3974 * configure: Rebuilt.
3976 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3978 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3980 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3982 * socket.c (scm_addr_vector): fix faulty scm_listify.
3984 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3986 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3987 style block comment is no longer considered an error.
3989 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3991 * PLUGIN/guile.libs.in: New file.
3992 * PLUGIN/guile.libs: Removed from repository.
3993 * configure.in: Create PLUGIN/guile.libs from
3994 PLUGIN/guile.libs.in. This is for including additonal libraries
3995 needed for dynamic linking.
3996 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3997 instead of PLUGIN/guile.libs.
3999 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
4001 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
4003 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
4004 occurrences of the given element from the list, not just the
4005 first. This is how the Emacs Lisp functions behave, how the
4006 analogous Common Lisp functions behave, and (I believe) how the
4007 older Maclisp functions worked. I realize that this change may
4008 break code, but it seemed better to break it before the Guile
4011 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
4012 Their prototypes were already present in gc.h, but they weren't
4014 (scm_init_storage): Initialize scm_protects.
4015 * root.c (scm_protects): New element of scm_sys_protects.
4017 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
4019 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4021 * libguile.h: Added #include "libguile/net_db.h".
4023 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
4024 30 change. That file is only meant for communication between the
4025 configuration process and load.c. If code linked against libguile
4026 wants to get at the paths mentioned in libpath.h, it can call
4027 functions declared in load.h.
4029 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4031 * libguile.h: Removed #include "libguile/fdsocket.h"
4033 * net_db.c: Added #include <sys/socket.h>.
4035 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
4037 * filesys.c (scm_input_waiting_p): use select in preference to
4038 FIONREAD, since the latter doesn't detect EOF.
4039 Throw error if neither select nor FIONREAD available.
4041 * socket.c (scm_connect): take a port, not a fd object.
4042 (scm_fill_sockaddr): throw an error if fam is not recognised.
4043 (scm_bind): use scm_fill_sockaddr.
4044 (scm_listen): take a port, not a fd object.
4045 (scm_accept): take and return a port. return #f in the car if
4046 address can't be got
4047 (scm_sock_fd_to_port): new procedure.
4048 (scm_socket): use scm_sock_fd_to_port.
4049 (scm_addr_vector): throw error if unrecognised address type.
4050 take an extra argument with the calling procedure name.
4051 (scm_getsockname): take a port. return #f if address can't be got.
4052 (scm_getpeername): take a port. return #f if address can't be got.
4053 (scm_recvfrom): take a port. return #f for address component if can't
4055 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
4056 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
4058 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
4060 * throw.c (scm_internal_catch): Make body funcs and handler funcs
4061 use separate data pointers, to allow them to be designed
4062 independently and reused.
4063 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
4064 Renamed from catch_body, catch_handler, and uncaught_throw; made
4066 (struct scm_catch_body_data): Renamed from catch_body_data; moved
4068 (scm_catch): Use the above.
4069 (scm_throw): Don't bother printing a message for an uncaught
4070 throw; we establish a default handler in init.
4071 * throw.h (scm_internal_catch): Prototype updated.
4072 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
4074 (struct scm_body_thunk_data): New structure, used as data
4075 argument to scm_body_thunk.
4076 * init.c (struct main_func_closure): New structure, packaging up
4077 the data to pass to the user's main function.
4078 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
4079 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
4080 scm_internal_catch to establish a catch-all handler, using
4081 scm_handle_by_message. This replaces the special-case code in
4083 (invoke_main_func): Body function for scm_internal_catch; invoke
4084 the user's main function, using the main_func_closure pointer to
4085 decide what to pass it.
4086 * root.c (struct cwdr_body_data): Remove handler_proc member.
4087 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
4088 (cwdr_handler): Removed.
4090 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4092 * socket.h (SCM_P): update bind prototype.
4093 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
4094 include "feature.h".
4095 (scm_socket): return a port, not a file descriptor object.
4096 include "fports.h" and <unistd.h>
4097 (scm_bind): take a port, not a file descriptor object.
4098 take an extra argument for address args.
4100 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
4101 INADDR_NONE, INADDR_LOOPBACK.
4103 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4105 * init.c: include net_db.h and not fdsocket.h.
4106 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
4108 * Makefile.am: corresponding changes.
4109 * socket.h: renamed from fdsocket.h, fix names.
4110 * net_db.h: renamed from socket.h, fix names.
4111 * socket.c: renamed from fdsocket.c.
4112 remove _sys from procedure names.
4113 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
4114 add "socket" to features list.
4115 * net_db.c: renamed from socket.c.
4116 remove _sys from procedure names.
4117 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
4118 add "net-db" to features list.
4119 include "net_db.h". don't include <sys/socket.h> or
4122 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4124 * tags.h (scm_tags): Removed comma at end of last enumerator.
4126 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
4128 Don't use GCC extensions to allocate space for debugging frames.
4129 (Here he goes again! Why do we put up with this?!)
4130 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
4131 an scm_debug_info structure, not an in-line array of them. Add
4132 'info' member, to say how many vect elements we've used, for eval
4134 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
4135 a new variable debug_info_end to mark the end of vect, instead of
4136 the address of the 'info' pointer itself.
4137 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
4138 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
4139 (SCM_APPLY): Explicitly allocate space for debug.vect.
4140 * debug.c (scm_m_start_stack): Same, for vframe.vect.
4141 * stacks.c: Adjusted for new debug frame structure.
4142 (RELOC_INFO, RELOC_FRAME): New macros.
4143 (stack_depth, read_frames): Use them, and new scm_debug_frame
4144 element 'info', instead of magically knowing that eval frames have
4145 an info pointer sitting after vect.
4146 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
4148 (scm_init_stacks): Formatting tweaks.
4150 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
4152 Give GCC more control flow information, so it can be sure that
4153 variables aren't used uninitialized.
4154 * error.h (scm_error, scm_syserror, scm_syserror_msg,
4155 scm_sysmissing, scm_num_overflow, scm_out_of_range,
4156 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
4157 scm_misc_error): Tell GCC that these functions never return.
4158 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
4159 out the field type, call abort if SCM_ASSERT returns, to placate
4161 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
4162 scm_wta ever returns. We can't handle this case anyway, and this
4163 gives the optimizer more information.
4164 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
4165 scm_wta ever returns.
4167 In some cases, the code is fine, but GCC isn't smart enough to
4168 figure that out; this usually happens when one variable is only
4169 initialized and used when a particular condition holds true, and
4170 we know that condition will never change within a given invocation
4171 of the function. In this case, we simply initialize the variables
4172 to placate the compiler, hopefully to a value which will cause a
4173 crash if it is ever actually used.
4174 * print.c (scm_iprin1): Initialize mw_pos.
4175 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
4176 * throw.c (scm_ithrow): Initialize dynpair.
4177 * unif.c (scm_uniform_vector_ref): Initialize cra.
4178 * struct.c (init_struct): Initialize prot.
4179 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
4181 * strports.c (scm_eval_0str): Don't return uninitialized garbage
4182 if EXPR contains no expressions.
4184 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
4186 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
4187 cause an infinite loop (???). So much for the algebraic
4188 equivalency of variable-sized arrays and alloca...
4190 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
4192 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
4193 a SCM boolean, not a C boolean.
4195 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
4197 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
4198 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
4199 rules for raising scm_mtrigger. Previously, unfortunate but not
4200 unlikely circumstances could result in almost constant invokation
4201 of the gc. Now, this situations should be less likely, but they
4202 are not prevented completely.
4204 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
4206 * numbers.c (scm_fuck): Procedure removed; looks like old test
4208 * numbers.h: Prototype removed.
4210 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
4212 * debug.h (scm_debug_frame): Change `vect' member from an in-line
4213 array to a pointer, to match my Nov 21 change in eval.c.
4215 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4217 * libguile.h: Added #include "libguile/backtrace.h", #include
4218 "libguile/stacks.h".
4220 * strings.c (scm_string scm_make_string scm_string_ref
4221 scm_string_set_x scm_string_equal_p scm_string_append):
4222 Bugfix according to scm patch from Aubrey Jaffer:
4223 Corrected long-standing
4224 (not (eqv? (integer->char 128)
4225 (string-ref (make-string 1 (integer->char 128)) 0)))
4226 bug found by John Kozak <jk@noontide.demon.co.uk>.
4228 * strports.c, strports.h: Make scm_eval_0str return the value of
4229 the last expression evaluated (previously, it returned void).
4231 * strports.c, strports.h: New function: scm_read_0str. Does what
4234 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4236 * simpos.c (scm_getenv): return #f if string can't be found in the
4237 environment instead of throwing an exception, for compatibility
4238 with numerous other systems.
4240 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
4242 * Makefile.am (.c.x): Use guile-snarf.
4243 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
4245 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
4247 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4249 * backtrace.c (scm_display_error_message): Made non-static, and
4250 renamed from display_error_message.
4251 * backtrace.h (scm_display_error_message): Added extern decl.
4252 * throw.c (uncaught_throw): Use it to display the error message.
4254 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
4256 * inet_aton.c: Use #if 0, not #ifdef 0.
4258 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
4260 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
4261 to convert the returned value.
4262 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
4263 the offset argument.
4265 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4267 Add new interface to catch/throw, usable from C as well as
4269 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
4270 (scm_internal_catch): New function, replaces...
4271 (scm_catch_apply): Deleted.
4272 * throw.c (scm_catch_apply): Deleted; replaced with a more general
4273 mechanism which is a bit more code, but can be used nicely from C
4274 and implement the Scheme semantics as well.
4275 (scm_internal_catch): This is the replacement; it's named after
4276 the analogous function in Emacs.
4277 (scm_catch): Reimplemented in terms of the above.
4278 (struct catch_body_data, catch_body, catch_handler): New
4279 functions, used by scm_catch.
4280 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
4281 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
4282 support for new cwdr.
4284 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
4287 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
4289 * acconfig.h: Added DYNAMIC_LINKING symbol.
4290 * configure.in: Add option and checks for dynamic linking.
4291 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
4292 dynl.h: New files for dynamic linking support.
4293 * Makefile.am (libguile_a_SOURCES):
4295 (modinclude_HEADERS): Added "dynl.h".
4296 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
4298 * init.c (scm_boot_guile_1): Call
4299 scm_init_dynamic_linking to initialize dynamic linking support.
4301 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
4303 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
4304 (as we Schemers say). It needs to be global, so that I can tweak
4305 it for the proper operation of unexec.
4306 (scm_boot_guile_1_live): New variable, see above.
4308 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
4310 * guile-snarf.sh: Removed.
4311 * PLUGIN/guile.libs: Added dependency for -lm.
4312 * acinclude.m4: Renamed from aclocal.m4.
4313 * PLUGIN/greet: Removed.
4314 * Makefile.am, aclocal.m4: New files.
4315 * configure.in: Updated for Automake.
4317 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
4319 * eval.c (scm_definedp): Use top_level_lookup_closure_var
4320 and not top_level_lookup_thunk_var.
4322 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
4324 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
4326 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
4328 * eval.c (scm_definedp): Incompatibly changed to be a builtin
4329 Scheme function, instead of syntax. Single argument is now a
4332 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4334 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
4335 scm_ra_divide): Properly terminate statements passed as arguments
4336 to IVDEP macros. (Thanks to Bernard Urban.)
4338 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
4339 with non-constant sizes. (Thanks to Bernard Urban.)
4341 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4343 It's an "eval closure", not an "eval thunk." A thunk is a
4344 function of no arguments.
4345 * root.h (struct scm_root_state): Renamed
4346 top_level_lookup_closure_var from top_level_lookup_thunk_var.
4347 (scm_top_level_lookup_closure_var): Renamed from
4348 scm_top_level_lookup_thunk_var.
4349 * root.c (mark_root): Uses changed.
4350 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
4351 * init.c (scm_start_stack): Uses changed.
4352 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
4353 Change scheme-visible name to *top-level-lookup-closure* from
4354 *top-level-lookup-thunk*.
4356 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
4358 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
4359 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
4361 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
4363 * gc.c (struct scm_heap_seg_data): Doc fixes.
4365 * gc.c (scm_gc_sweep): Empty all segments' freelists before
4366 sweeping. Then, prepend each segment's free cells to its
4367 freelist, rather than wiping out the old value. (Thanks to Marius
4370 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
4371 scm_check_freelist, scm_debug_newcell): New functions and
4372 variables, for debugging freelist problems.
4373 * pairs.h (SCM_NEWCELL): New debugging version added.
4374 * gc.h (scm_debug_newcell): Added extern declaration, used by
4375 debugging version of SCM_NEWCELL.
4377 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4379 On some systems <libc.h> conflicts with <unistd.h>, and should not
4380 be #included at all.
4381 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
4382 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
4383 * configure.in: Call it.
4384 * posix.c, filesys.c: Use its results to decide whether or not to
4386 * configure, scmconfig.h.in: Rebuilt with autoconf and
4389 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4391 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
4392 pointer to the stdio stream before calling scm_setbuf0, so the
4393 latter will be able to retrieve it. I'm surprised this didn't
4394 segfault earlier. (Thanks to Christopher Lee.)
4396 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4398 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
4401 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4403 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
4404 number of stack narrowing specifier pairs. The first specifier in
4405 a pair controls inner border, the second the outer border. A
4406 number means cut that number of frames, a procedure object means
4407 cut until that object is found in operator position in a frame.
4409 * root.c (cwdr): Bugfix.
4411 * read.c: Recording of positions disabled by default.
4413 * procs.c (scm_closure_p): New function.
4415 * posix.c (scm_tmpnam): New function.
4417 * load.c: Added #include "throw.h".
4418 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
4421 * load.c, load.h (scm_read_and_eval_x): New function.
4423 * eval.c: Renamed debug option "deval" to "debug".
4425 (scm_eval_x): `eval!' is no longer accessible from the scheme
4426 level. Motivation: We can't allow operations which introduce
4427 glocs into the scheme level. Guile's type system can't handle
4428 these as data. Use `eval' or `read-and-eval!' as replacement.
4430 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
4431 SCM_CONSP since this is a macro!; Set vframe.prev to
4432 scm_last_debug_frame instead of 0. In this way we can look
4433 "above" the virtual start stack frame if we wish.
4434 (scm_debug_hang): New function: Useful for debugging Guile in
4435 certain tricky situations. Will probably be removed later...
4437 * debug.h: Changed semantics of debug option "backtrace". This
4438 option now only indicates whether we want automatic backtrace at
4441 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4443 * ports.c: #include "filesys.h"
4444 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
4446 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
4447 Motivation: This is system specific code which is related to file
4448 I/O. It also may use select. Added code by Gary Houston to
4449 detect presence of character in stdio buffers.
4451 * libguile.h: #include "libguile/libpath.h"
4453 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4454 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4455 SCM_SITE_DIR; Install libpath.h among the other include files.
4457 * load.c, load.h (scm_sys_package_data_dir): New function.
4459 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4461 * stacks.h: Bugfix: Don't use tail-array length field as stack
4462 length field! This screwed GC.
4464 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4466 * _scm.h: Added #ifndef around definition of macros min and max.
4468 * __scm.h: Added hooks for threads to plugin to in ints protection
4469 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4470 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4471 the main code in these macros duplicated and spread over multiple
4472 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4473 SCM_THREAD_SWITCHING_CODE.
4475 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4477 * snarf.h: New file.
4478 * guile-snarf.sh: New file.
4479 * Makefile.in (inner_h_files): Added snarf.h
4480 (ancillary, install, uninstall, distclean): Added actions for
4482 (.c.x): Use guile-snarf.
4483 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4484 (gen_c_files): Note that these depend on guile-snarf.
4485 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4486 now in "snarf.h". Added #include "snarf.h" to get them.
4487 * libguile.h: Added #include "snarf.h".
4488 (Patches applied and tweaked by Jim Blandy.)
4490 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4492 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4493 standards suggest against providing prototypes for system
4494 functions. Thanks to Greg Troxel.
4496 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4498 * strports.c (scm_eval_0str): New function.
4499 #include "read.h", to get prototype for scm_read.
4500 * Makefile.in (strports.o): Update dependencies.
4501 * strports.h: New prototype.
4503 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4504 scheme name from "int?" to "integer?". It seems to do the job.
4505 * numbers.h: Rename prototype too.
4506 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4509 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4510 scm_num_eq_p): Rename these according to R4RS conventions: call
4511 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4512 to making libguile R4RS compliant without ice-9...
4514 * load.c (scm_sys_search_load_path): Search for files under all
4515 extensions listed in the %load-extensions variable. If FILENAME
4516 is absolute, return it unchanged, without searching the load path.
4517 (scm_loc_load_extensions): New variable, pointing to
4518 %load-extensions' value cell.
4519 (scm_init_load): Initialize it, and the value it points to.
4520 (scm_primitive_load_path): Improve error reporting.
4522 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4523 of new Scheme variable %load-hook.
4524 (scm_primitive_load): Apply %load-hook to filename.
4526 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4528 * configure.in: add tests for figuring out whether buffered data
4529 is available in a FILE structure, which is needed by char-ready.
4531 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4534 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4535 exceptions using misc_error instead of syserror. It seems a bit
4536 odd to throw an exception if a string can't be found in the
4537 environment, but it's consistent with open-file, stat etc.
4538 (simpos.h): remove sys_ from getenv.
4540 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4541 occurs, throw an error instead of returning errno. Return value
4543 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4545 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4547 * filesys.c (scm_stat2scm): derive file type and permissions from
4548 the stat mode and append them to the returned vector.
4549 There isn't much overhead in doing this and it avoids the need to
4550 work with S_IRUSR et al. in Scheme.
4551 Define symbols scm_sym_regular etc.
4552 (scm_init_filesys): don't intern S_IRUSR etc.
4554 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4555 and s_primitive_load_path.
4557 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4559 * error.h: don't declare error symbols. prototype for scm_misc_error.
4561 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4564 * error.c: use SCM_SYMBOL to set up error keys.
4565 scm_misc_error: new procedure.
4567 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4569 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4570 between `#!' and `!#' is ignored.
4571 (skip_scsh_block_comment): New function.
4573 * feature.c (scm_set_program_arguments): New argument, FIRST.
4574 * feature.h: Update prototype.
4575 * init.c (scm_boot_guile_1): Pass new argument to
4576 scm_set_program_arguments.
4578 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4580 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4581 (scm_boot_guile): Call scm_set_program_arguments here, later than
4582 the old initialization.
4584 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4585 initialization procedure.
4586 - Delete in, out, err arguments; there are other perfectly good
4587 ways to override these when desired.
4588 - Delete result argument; this function shouldn't ever return.
4589 - Rename init_func argument to main_func, for less confusion.
4590 - Delete boot_cmd argument; main_func is more general.
4591 -Add 'closure' argument, to help people pass data to main_func
4592 without resorting to global variables.
4593 - Abort if reentered; don't bother returning an error code.
4594 - Call scm_init_standard_ports to set up the default/current
4595 standard ports; no need to pass them to scm_start_stack.
4596 - Remove code to evaluate the boot_cmd, and start the repl; let
4597 the user do something like that in main_func if they want.
4598 - Remove code to package up a return value; main_func can do any
4600 - Call exit (0), instead of returning.
4601 (scm_start_stack): Don't initialize the I/O ports here; that's
4602 weird. Delete in, out, err arguments. Move guts to
4603 scm_init_standard_ports, scm_stdio_to_port.
4604 (scm_init_standard_ports): New function, to set up current and
4605 default standard ports.
4606 (scm_start_stack, scm_restart_stack): Make these static.
4607 * init.h (scm_boot_guile): Adjust declaration.
4608 (scm_start_stack, scm_restart_stack): Remove externally
4609 visible declarations for these.
4610 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4612 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4613 written out several times in scm_start_stack.
4614 * fports.h: New declaration for the above.
4616 * feature.c (scm_set_program_arguments): New function.
4617 * feature.h: New declaration for the above.
4619 * ports.c: Formatting tweak.
4621 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4623 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4624 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4625 for obtaining the address of a car or cdr field. Motivation:
4626 &SCM_CXR make assumptions about the internal structure of the
4629 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4630 Motivation: see SCM_CXRLOC.
4632 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4633 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4634 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4635 Motivation: Safer use. Some other macros are defined in terms of
4636 these operations. If these are defined using the SCM_SETCXR
4637 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4638 to inefficiency and an <e1> with side-effects could potentially
4639 break. Also, these particular operations are heavily utilized in
4640 the garbage collector. In unoptimized code there will be a
4643 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4644 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4645 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4646 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4647 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4648 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4649 vports.c: Cleaned up use of pairs: Don't make any special
4650 assumptions about the internal structure of selectors and
4651 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4652 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4653 (Among other things, this change makes it easier to build Guile
4654 with certain compilers which have problems with casted lvalues.)
4656 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4658 * stacks.c: Improve selection of relevant stack frames when making
4659 a stack object. Introduce one level of indirection in the stack
4660 object to make it possible to "narrow" to a certain region of the
4661 stack. This facilitates making use of more clever algorithms (not
4662 implemented) for selecting relevant frames and gives a cleaner
4663 design since selection of frames can be done independently of
4664 extraction of frames from the real stack.
4665 (scm_stack_id): Also take #t as argument which means look at
4668 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4669 Turn n_tail into an integer directly representing current number
4670 of frames in stack. Add field tail.
4672 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4674 * debug.c (scm_make_memoized): Made it available at scheme level.
4675 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4676 SCM_NIMP before applying heavier predicates in argument checking.
4677 (scm_local_eval): Also take memoized object as argument.
4679 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4680 aren't created with zero length, but should such a strange
4681 creature suddenly turn up...
4683 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4685 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4686 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4688 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4690 * variable.c (scm_make_variable): Make the name hint optional, as
4692 (anonymous_variable_sym): Renamed from variable_sym. All uses
4695 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4696 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4697 of scm_primitive_load_path was also changed to
4698 "primitive-load-path", from "%try-load-path". Callers changed.
4699 We'd like to respect the convention that a function named
4700 "try-mumble" should behave just like the function called "mumble",
4701 but return #f instead of signalling some error.
4702 * load.h: Rename prototypes.
4704 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4706 * print.c (make_print_state, grow_print_state), print.h: Modified
4707 the print state representation: Don't use a tail array for
4708 recording of circular references. Resizing of the print state
4709 structure invalidates the print state pointer. To avoid passing
4710 around an indirect print state reference to all printing
4711 functions, we instead let the print state reference a resizable
4714 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4716 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4717 Don't crash when passed an improper list terminated by a
4718 non-immediate value.
4720 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4722 Allocate data for structures on an eight-byte boundary, as
4723 required by the tagging system.
4724 * struct.c (alloc_struct): New function.
4725 (scm_make_struct, scm_make_vtable_vtable): Call it.
4726 * struct.h (scm_struct_n_extra_words): Bump to 3.
4727 (scm_struct_i_ptr): New "field".
4728 * gc.c (scm_gc_sweep): When we need to free the data, use the
4729 information stored by alloc_struct to find the beginning of the
4730 block allocated to the structure, so we can free it.
4732 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4734 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4737 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4738 (scm_debug_info): New member: id.
4740 * stacks.c: Stacks are now represented as structs; Stacks have an
4741 id given to them by `start-stack'.
4742 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4744 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4745 Changed stack representation.
4747 * debug.c (scm_procedure_name): Try procedure property `name' for
4748 compiled closures aswell.
4750 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4752 * eval.c: scm_i_name moved to gsubr.c
4753 (scm_m_define): Record names of all kinds of procedure
4754 objects. (Earlier, only closures were recorded.)
4756 * procprop.h: Added declaration of scm_i_name.
4758 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4759 (scm_make_gsubr): Record names of compiled closures.
4761 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4763 * debug.c, debug.h: Removed obsolete code.
4765 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4766 stacks.c: Renamed regs --> scm_contregs.
4768 * print.c (scm_free_print_state): Cleanup print state before
4769 returning it to pool. It is better to do it here than in
4770 scm_prin1 since scm_prin1 is called often.
4772 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4773 s_set_source_property_x): Check that first argument is a pair or a
4776 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4777 scm_i_line, scm_i_column and scm_i_breakpoint global.
4779 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4780 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4783 * debug.h: Added debug object smob declaration and macro
4786 * configure.in: Build with backtrace.o and stacks.o if debug
4789 * Makefile.in: Added entries for new files: backtrace.c,
4790 backtrace.h, stacks.c and stacks.h.
4792 * symbols.c (scm_sym2ovcell): Fixed documentation.
4794 * _scm.h (min, max): Added.
4796 * async.c: Moved `min' macro to _scm.h.
4798 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4799 SCM_BACKTRACE_INDENT.
4801 * eval.c: Added new debug options `maxdepth' and `indent'.
4803 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4805 * print.h: Added selector SCM_PRINT_STATE.
4807 * print.c: New functions: scm_make_print_state,
4808 scm_free_print_state.
4810 * print.h: Added declarations for scm_make_print_state,
4811 scm_free_print_state.
4813 * debug.c (scm_m_start_stack): New acro.
4815 * debug.h: Small cleanup.
4817 * init.c (scm_boot_guile_1): Moved scm_init_debug below
4820 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4822 * __scm.h, alist.c, alist.h, append.c, append.h, appinit.c,
4823 arbiters.c, arbiters.h, async.c, async.h, boolean.c, boolean.h,

4845 More prototype-related changes from Marius Vollmer:
4846 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4847 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4848 * ports.h (ptobfuns): Added prototypes. This means some casting in
4850 * fports.c: Added casts for initializations, since the functions
4851 are defined to take FILE * as their stream argument, not SCM.
4852 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4853 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4854 to `char *str_data' to conform to prototype.
4856 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4858 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4860 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4862 * stime.c, stime.h: use SCM_P method.
4864 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4866 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4867 be given at least two arguments. Insist that lst's last element
4868 be a list, but don't make any requirements of its predecessors.
4870 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4872 * eval.c (scm_nconc2last): Revert last change; there seems to be
4873 other stuff going on here.
4875 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4877 * eval.c (scm_nconc2last): Make sure that each element of lst
4878 (which is a list of argument lists, except for the tail) is a
4879 proper list, i.e., finite and terminated by '().
4881 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4883 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4886 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4887 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4890 * vectors.c (scm_make_vector): Fill vectors with the undefined
4891 value, to help make Guile Scheme code more portable to other
4894 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4895 * symbols.h, tags.h: Doc fixes.
4897 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4899 * async.c (scm_take_signal): Doc fixes.
4901 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4903 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4904 want to subtract it from the modulus; we just want to leave it
4907 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4909 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4912 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4914 * throw.c (scm_catch_apply): Finished implementation of
4917 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4919 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4921 (scm_init_filesys): set "i/o-extensions" feature.
4924 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4926 * Makefile.in (root.o): Correct dependencies.
4928 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4930 * Makefile.in: Added dependency entry for root.o.
4932 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4933 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4935 * init.c (scm_start_stack): Set initial root continuation number
4938 * procs.c: New function: scm_thunk_p.
4940 * procs.h: Added declarations of scm_thunk_p.
4942 * root.c: Renamed `call-with-new-root' -->
4943 `call-with-dynamic-root'.
4944 (cwdr): Removed allocation of new root state. This should be done
4945 separately by use of scm_make_root.
4946 (scm_apply_with_dynamic_root): New function: Does what it
4947 sounds like. Needed when spawning threads.
4949 * root.h: Added member last_debug_frame to root state.
4950 Added #include "libguile/debug.h"
4952 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4953 arguments. The motivation is that code in root.c needs catch
4954 functionality, and we want to avoid code duplication.
4955 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4956 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4957 handlers that run without popping the stack into the dynwind
4960 * throw.h: Added prototypes for scm_catch_apply and
4963 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4965 * root.h (scm_root, scm_set_root): Decouple thread support details
4966 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4967 SCM_SET_THREAD_LOCAL_DATA.
4969 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4970 and tortoise scanning loop.
4972 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4974 * Makefile.in: Rebuild dependencies.
4976 * libguile.h: #include "libguile/print.h" before "smob.h", since
4977 the latter uses the print_state structure.
4979 * throw.c (scm_ithrow): Use the correct variable when checking to
4980 see if a given element of scm_dynwinds is a valid catch.
4982 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4983 structure, abort; don't just silently ignore the garbage.
4985 * _scm.h: #include "print.h" here, since it seems to be used just
4987 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4988 strports.c, unif.h: Don't #include "print.h".
4990 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4992 * feature.h (scm_loc_features): Removed external declaration.
4993 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4995 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4997 * feature.c (scm_init_feature): Added threads feature (needs to be
4998 initialized here, since features doesn't exist when
4999 scm_init_threads is called).
5001 * libguile.h: Added #include "libguile/../threads/threads.h".
5002 (This is a kludge to get thread support working. This should be
5005 * configure.in, acconfig.h: Added flags for thread support.
5007 * scmsigs.c: Define `signal' to be `pthread_signal' if using
5010 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
5011 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
5014 * _scm.h: Added conditional #include "threads.h"
5016 * __scm.h (SCM_ASYNC_TICK): Added call to macro
5017 SCM_THREADS_SWITCHING_CODE.
5019 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
5020 allocate the basic dynamic root object.
5021 (scm_boot_guile): Added call to scm_init_root.
5023 * root.c, root.h: Added root smob.
5024 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
5025 functions: Implements dynamic roots mostly according to spec in
5026 SCM manual. Main difference is that the second argument is a
5027 throw handler rather than an error "thunk".
5029 * root.h: Added declaration of scm_init_root.
5031 * root.c: Added #include "genio.h", #include "smob.h", #include
5032 "pairs.h", #include "throw.h", #include "dynwind.h", #include
5034 (scm_init_root): Added #include "root.x".
5036 * throw.c: Added #include "stackchk.h"
5037 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
5038 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
5039 can be used in scm_call_with_new_root; Added reenabling of stack
5040 checking when catching a throw.
5042 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
5044 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
5046 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
5047 element is not found, as per R4RS.
5049 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
5051 * list.c: Doc fixes throughout.
5053 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
5055 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
5056 declare the char * to be const. Avoids a warning in rgx.c.
5058 * ports.h: spelling fix.
5060 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
5063 * load.c (scm_sys_try_load_path): throw an error if file not found
5064 (like it says it in NEWS).
5066 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
5068 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
5069 PROPS slot to '(), not #f; it's an empty alist.
5071 * throw.h, throw.c: Use SCM_P instead of #if hair.
5073 Remove special support for uncaught throws; see throw.c for
5075 * throw.c (uncaught_throw): New function.
5076 (scm_ithrow): Call uncaught_throw if we don't find a throw
5077 target; don't mess with scm_bad_throw_vcell.
5078 (scm_bad_throw_vcell): Variable deleted.
5079 (scm_init_throw): Don't initialize it.
5081 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
5084 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
5086 * numbers.c (scm_istr2int): If the number is short (as most
5087 numbers are), just call scm_small_istr2int to deal with it.
5088 (scm_small_istr2int): New function, created by un-#ifdefing the
5089 non-bignum version of scm_istr2int and renaming it.
5091 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
5093 * load.c (scm_sys_try_load): don't check whether value returned
5094 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
5095 Change the Scheme name from %try-load to primitive-load.
5097 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
5098 Can avoid passing a message, allowing it to be derived in the
5099 error handler (e.g., if we want to throw to the key both from
5102 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
5104 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
5105 references now have a new appearance which is more compact and
5106 also gives a clue about what the target of the reference is.
5107 By setting parameters in the print state, more fancy printing can
5108 be achieved. This is used by the (not yet commited) backtrace
5111 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
5113 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
5116 * print.c: Added #include "struct.h". Removed function
5119 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
5120 scm_iprin1. Removed prototype for scm_prlist.
5122 * arbiters.c (prinarb),
5123 async.c (print_async),
5124 debug.c (prindebugobj, prinmemoized),
5125 eval.c (prinprom, prinmacro),
5126 filesys.c (scm_fd_print, scm_dir_print),
5128 mallocs.c (prinmalloc),
5129 numbers.c, numbers.h (scm_floprint, scm_bigprint),
5130 smob.h (scm_smobfuns),
5131 srcprop.c (prinsrcprops),
5133 unif.c, unif.h (scm_raprin1, rapr1),
5134 variable.c (prin_var): Changed argument `int writing' to
5135 `scm_print_state *pstate'.
5137 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
5138 that it will be called before scm_init_print.
5140 * print.c (scm_prin1): Print states are now allocated when calling
5141 scm_prin1 and then passed around to all printing functions as an
5142 argument. A cache `print_state_pool' enables reuse of print
5144 (scm_make_print_state): New function.
5145 (scm_iprin1): Adaption to print states.
5146 (scm_iprlist): An initial "hare and tortoise" scan brings down
5147 time complexity to O (depth * N). (Better time complexity will be
5148 achieved when the printing code is completely rewritten.)
5150 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
5152 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
5153 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
5154 it gets done whether or not the cache variable has a value.
5156 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5158 Distinguish #f and ().
5159 * __scm.h: #undef SICP.
5160 * pairs.h (SCM_EOL): Delete this definition, equating it with
5162 * tags.h (SCM_EOL): Give it a new definition here; I think I found
5163 the value it used to have. Doc fixes, too.
5165 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
5167 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
5168 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
5169 Lord's implementation of structs, allowing for tail arrays as
5170 described in the manual. Also fixed some bugs. (Both the interface
5171 and the implementation should be improved.)
5173 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
5175 * print.c, print.h: Closures now print like #<procedure foo (x)>.
5176 People who whish to see the source can do `(print-enable 'source)'.
5177 Removed #ifdef DEBUG_EXTENSIONS.
5179 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5181 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
5182 integer (assuming for now accepting an integer is a good thing).
5184 * error.c, fports.c: replace use of %S in lgh_error args with %s.
5185 %S will be used instead for write'ing arguments.
5187 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
5188 asserts. fix a few other asserts.
5189 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
5190 scm_uniform_vector_ref, scm_array_set_x,
5191 scm_dimensions_to_unform_array): change args in
5192 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
5193 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
5194 scm_substring_fill_x): likewise.
5195 gsubr.c (scm_gsubr_apply): likewise.
5196 eval.c (SCM_APPLY): likewise.
5198 * eval.c (4 places): replace scm_everr with lgh_error or
5201 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
5202 scm_memory_error): new procedures.
5203 scm_everr: deleted. can use scm_wta, dropping first two args.
5204 scm_error: convert NULL subr to SCM_BOOL_F.
5206 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
5209 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
5212 * error.c, error.h: new error keys: scm_arg_type_key,
5213 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
5215 scm_wta: reimplement using lgh_error instead of scm_everr.
5217 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
5219 * gdbint.c: scm_lread now has one more argument.
5221 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
5222 scm_port_\1; Added mutator scm_set_port_filename_x (used when
5223 loading source from non-file ports, which, e. g., happens when
5224 using the Emacs interface).
5226 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
5229 * read.c: Added code for recording of positions of source code
5230 expressions; New functions: recsexpr, scm_lreadrecparen;
5231 _scm_make_srcprops --> scm_make_srcprops
5232 (scm_flush_ws): Removed updating of positions counters. This work
5233 is already done by scm_gen_getc
5235 * read.h: Added prototype for scm_lreadrecparen
5237 * print.c: Added #include "alist.h"
5239 * eval.c: Added #include "hash.h"
5241 * eq.c: Added #include "ramap.h"
5243 * options.c: Documentation fixes.
5245 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
5246 (scm_init_srcprop): Adjusted size of initial source-whash. Name
5247 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
5248 --> scm_make_srcprops
5250 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
5251 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
5252 function calls in the definition of the whash access macros.
5254 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
5256 * init.c (scm_boot_guile): Add level of indirection to
5257 scm_boot_guile_1() to ensure that stack base pointer is properly
5258 initialized. There was no guarantee that variable i was the
5259 highest/lowest variable on stack (i.e. the call frame of
5260 scm_boot_guile was not completely protected from gc).
5262 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
5264 * ports.h (scm_port_table): put back file_name, it will be used to
5265 support debugging. Undo related changes in fports.c, ioext.c,
5268 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5270 * ports.h (scm_port_table): remove file_name member for now, it seems
5272 * fports.c (scm_open_file): don't set file_name in PTAB.
5273 (prinfport): don't use file_name in PTAB.
5274 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
5275 * ports.c (scm_add_to_port_table): don't intialize file_name.
5276 (scm_port_file_name): remove for now.
5277 * gc.c (scm_gc_mark): don't mark PTAB file_name.
5279 * fports.h (scm_mkfile): prototype deleted.
5280 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
5282 * debug.c, unif.c: use scm_out_of_range instead of
5283 wta for range errors (ASSERT still needs work).
5285 * error.c, error.h (scm_out_of_range): new procedure.
5287 * error.c, error.h (scm_out_of_range_key): new key.
5289 * posix.c (scm_sync): #else was missing.
5291 * error.c, error.h: append _key to names scm_num_overflow and
5294 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
5295 of consing an empty list.
5296 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
5297 of macros, saves code and string space.
5298 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
5299 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
5300 lower case. Rename scm_syserror_m to scm_syserror_msg.
5301 error.h: prototypes for new procedures.
5303 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
5305 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
5307 * error.c, error.h: setup scm_num_overflow key.
5309 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
5310 Remove definition of SCM_OVSCM_FLOW.
5312 * fports.c (scm_open_file): use SCM_SYSERROR_M.
5314 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
5315 explicit message and args.
5317 * error.c, error.h, __scm.h: change system_error_sym to
5320 * error.c (system_error_sym): remove leading %% from the Scheme name
5323 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
5325 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5327 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
5328 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
5329 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
5330 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
5331 renamed. (These were introduced by unsupervised name
5334 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5336 * print.c: Added code for detection of circular references during
5337 printing. (init_ref_stack, grow_ref_stack): New functions. Added
5338 a hook for printing of closures (accessible via print options).
5339 This leads to a split of calls to scm_iprin1 into two classes:
5340 elementary print operations (e. g. the code which prints a smob)
5341 still use scm_iprin1 while top level calls (like scm_display) use
5342 scm_prin1. scm_prin1 begins by clearing the data structure used
5343 to record reference information.
5345 * print.h: Added declarations of scm_prin1 and scm_prlist.
5347 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
5349 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
5351 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
5353 * error.c (err_head): scm_iprin1 --> scm_prin1
5355 * debug.c: Adjusted header comment.
5359 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
5361 * strerror.c: Doc fix.
5363 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5365 * gdbint.c (gdb_read): Now possible to run during GC.
5366 (unmark_port, remark_port): New functions.
5368 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
5370 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
5371 of allocating a new string object. Also, increase size by
5372 the factor 2 instead of 1.5.
5374 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
5376 * __scm.h (SCM_P): Corrected to run under traditional C.
5378 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
5381 * async.c: Calls to scm_sysintern corrected.
5383 * async.h (scm_async_clock): Redundant declaration removed.
5385 * continuations.c (scm_dynthrow): Redundant declaration removed.
5387 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
5388 Definition typos corrected.
5390 * debug.h: Missing declarations of functions in debug.c added
5393 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
5394 Missing declarations to functions in eval.c added.
5396 * filesys.c: Possibly uninitialized variable rv.
5398 * gc.h (scm_object_addr, scm_unhash_name): Missing
5399 declarations of functions defined in gc.c added.
5401 * genio.c: Possible typos str_data -> wstr_data. ???
5403 * genio.c: Possibly unintended shadowing of local variable
5404 `int c' (gotos out of scope of inner `c'). ???
5406 * init.c: Uninitialized `SCM last' may be used.
5408 * ioext.h: (scm_sys_isatty_p): Typo.
5410 * list.h (scm_list_head): Missing prototype for function in
5413 * numbers.c (scm_two_doubles): Changed from extern to static
5414 (is used only within numbers.c).
5416 * numbers.h: Repeated declarations removed.
5418 * ports.h (scm_close_all_ports_except): Declaration for the
5419 function defined in ports.c added.
5421 * posix.h: Missing declarations added.
5423 * procs.h (scm_make_subr_opt): Missing declaration added.
5425 * socket.h (scm_sys_gethost): Missing declaration added.
5427 * socket.h: Redundant declarations removed (they are in fdsocket.h).
5429 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
5430 Missing declarations added.
5432 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
5434 * struct.c: Uninitialized variable `SCM answer' may be used.
5436 * unif.c (l2ra): Declaration prototype.
5438 * unif.c (scm_array_equal_p): Dummy definition removed (it is
5439 defined in ramap.c).
5441 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
5442 Redundant declarations removed (they are in ramap.h).
5444 * variable.h (scm_make_udvariable,
5445 scm_make_undefined_variable): Declaration corrected to
5446 correspond variable.c.
5448 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
5449 Missing declarations added.
5451 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5453 * Makefile.in (distclean): Don't forget to delete fd.h.
5455 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5457 * fd.h.in, tags.h: Trivial cleanups.
5459 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5460 marksweep.h just declared functions from gc.c.
5461 * gc.h, libguile.h: Don't #include "marksweep.h".
5462 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5463 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5464 dependencies updated.
5466 * libguile.h: Don't #include "files.h"; it's been deleted.
5468 * files.c (scm_sys_delete_file): Moved to filesys.c.
5469 File is now empty; deleted.
5471 * filesys.c: scm_sys_delete_file is now here. Remove
5472 #if's; they seem to rely on remnants of an old portability
5473 regimen. If the problems come up again, solve them properly,
5474 using autoconf. Specifically: Don't test M_SYSV, and #define
5475 remove to be unlink if it's #defined; don't use remove just
5476 because HAVE_STDC_HEADERS is #defined.
5477 * filesys.h: Add declarations for scm_sys_delete_file.
5478 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5479 files.o, files.h, files.c, and files.x.
5480 * init.c: Don't #include "files.h", and don't call scm_init_files.
5482 Use SCM_P instead of PROTO; the latter intrudes on the user's
5484 * params.h: Deleted; definition of SCM_P moved to...
5485 * __scm.h: ... here, where it replaces PROTO macro.
5486 * libguile.h, smob.h: Don't #include "params.h".
5487 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5488 smob.h: Fix prototypes accordingly.
5489 * Makefile.in: Update dependencies.
5490 (inner_h_files): Remove params.h.
5492 * gc.c: #include "gc.h"; every module should include its header,
5493 to let the compiler cross-check the declarations against the
5496 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5497 simpos.h: #include "libguile/__scm.h".
5499 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5501 * init.c: Don't forget to #include smob.h and init.h.
5502 * Makefile.in: Dependencies updated.
5504 * smob.h: Use PROTO instead of #if __STDC__.
5506 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5508 * __scm.h: Doc fixes.
5510 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5511 <angles>; this allows `make depends' to work properly.
5513 * libguile.h: #include smob.h and pairs.h before the others; they
5514 define typedefs used by other headers.
5516 C files should #include only the header files they need, not
5517 libguile.h (which #includes all the header files); the pointless
5518 recompilation was wasting my time.
5519 * Makefile.in (all .o dependency lists): Regenerated.
5520 * libguile.h: Don't try to get a definition for size_t here...
5521 * __scm.h: Do it here.
5522 * _scm.h: Since this is the internal libguile header, put things
5523 here that all (or a majority) of the libguile files will want.
5524 Don't #include <libguile.h> here; that generates dependencies on
5525 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5526 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5527 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5624 * weaks.c: Get "weaks.h".
5626 * stackchk.h: #include "libguile/debug.h",
5628 * print.h, read.h: #include "options.h", since everyone who uses
5629 either of these files will need that.
5631 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5632 anyone who uses this file will need them to define the smob
5633 printing functions. Also, get markers.h, since people will need
5634 to #define the mark functions.
5636 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5637 * ports.h: ... to here.
5639 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5640 don't rely on archaic C default type rules.
5642 * fports.h: #include "libguile/ports.h", since you need that in
5643 order to parse this.
5645 * genio.h: #include "libguile/print.h", because you need that to
5646 parse this; don't bother #including "ports.h", since print.h gets
5649 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5651 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5652 this; it's now a reference to an element of *scm_root.
5654 * debug.h: Don't #include "options.h"; the compiler won't be able
5655 to find that once the headers are installed; instead, #include
5656 "libguile/options.h".
5657 * gc.h: Same, with marksweep.h.
5658 * mbstrings.h: Same, with symbols.h.
5659 * scmhob.h: Same, with _scm.h.
5660 * smob.h: Same, with params.h.
5662 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5663 C files; there's no need for this, and it forces recompilations
5666 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5668 * error.c (scm_error): declare scm_error_callback.
5670 * error.h: prototype for scm_error_callback.
5672 * __scm.h: define lgh_error.
5673 (SCM_SYSERROR): redefine using lgh_error.
5675 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5677 * error.c (scm_error): new procedure.
5679 * error.h: prototype for scm_error.
5681 * Makefile.in (install): install scmconfig.h from the current
5682 directory, not $(srcdir).
5684 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5686 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5687 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5688 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

5694 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5695 vports.h, weaks.h: #include "libguile/__scm.h", not
5696 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5697 dependencies are within libguile properly.
5699 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5701 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5702 when scmconfig.h doesn't exist.
5704 * load.c (scm_sys_try_load): Correct spelling.
5706 * feature.c (scm_loc_features): Make this static.
5708 * Makefile.in (libpath.h): Omit trailing slash from path. We
5709 shouldn't require it of users, so why put it here?
5711 Move code to initialize and search %load-path from ice-9 to C
5712 code, so we can use the load-path to find the ice-9 boot code;
5713 this makes it easier to run Guile without installing it. See
5714 corresponding changes in guile/Makefile.in.
5715 * feature.c: Move stuff concerned with the load path to load.c.
5716 (scm_compiled_library_path): Deleted.
5717 Don't #include libpath.h here.
5718 * feature.h: Don't mention scm_compiled_library_path.
5719 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5720 <sys/stat.h>, and <unistd.h> (if present).
5721 (R_OK): #define if the system hasn't deigned to.
5722 (scm_loc_load_path): New variable.
5723 (scm_init_load_path, scm_sys_search_load_path,
5724 scm_sys_try_load_path): New functions.
5725 (scm_init_load): Initialize scm_loc_load_path to point to the
5726 value cell of the Scheme %load-path variable.
5727 * load.h: Add declarations for scm_sys_search_load_path,
5728 scm_sys_try_load_path.
5729 * init.c: Call scm_init_load_path.
5730 * Makefile.in (feature.o, load.o): Dependencies updated.
5732 * load.c, load.h: Rewrite using PROTO macro.
5734 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5736 * gc.c (scm_cellp): New function: C predicate to determine if an
5737 SCM value can be regarded as a pointer to a cell on the heap.
5739 * gc.h: Added declaration of scm_cellp.
5741 * gdb_interface.h: New file: The GDB interface header from the GDB
5744 * gdbint.c: New file: GDB interface.
5746 * gdbint.h: New file: GDB interface.
5748 * libguile.h: Added #include <libguile/gdbint.h>.
5750 * init.c (scm_boot_guile): Added scm_init_gdbint.
5752 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5753 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5754 found if object files and source are kept separate).
5756 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5758 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5760 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5762 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5763 TK_SRC_DIR; they're not relevant any more.
5765 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5766 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5768 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5770 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5771 search path, so we can find the <libguile/MUMBLE.h> headers.
5773 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5775 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5776 implicit in the .c.o rule.
5777 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5780 Put the library path in a header file, instead of passing it on
5781 the command line in every compilation.
5782 * Makefile.in (libpath.h): New target.
5783 (feature.o): Depend on libpath.h.
5784 (clean): Delete libpath.h.
5785 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5786 * feature.c: ... #include "libpath.h" here.
5787 * .cvsignore: Ignore libpath.h.
5789 Don't install the unwashed masses of Guile header files in the
5790 main #include path; put most of them in a subdirectory called
5791 'libguile'. This avoids naming conflicts between Guile header
5792 files and system header files (of which there were a few).
5793 * Makefile.in (pkgincludedir): Deleted.
5794 (innerincludedir): New variable; this and $(includedir) are enough.
5795 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5796 (installed_h_files): Divide this up. Now this variable lists
5797 those header files which should go into $(includedir) (i.e. appear
5798 directly in the #include path), and ...
5799 (inner_h_files): ... this new variable says which files appear in
5800 a subdirectory, and are referred to as <libguile/mumble.h>.
5801 (h_files): List them both.
5802 (install): Create innerincludedir, not pkgincludedir. Put
5803 the installed_h_files and inner_h_files in their proper places.
5804 (uninstall): Corresponding changes.
5805 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5806 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5807 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5808 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5809 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5810 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5811 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5812 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5813 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5814 vports.h, weaks.h: Find __scm.h in its new location.
5815 * __scm.h: Find scmconfig.h and tags.h in their new locations
5816 (they're both "inner" files).
5818 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5820 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5822 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5824 * posix.c: Doc fixes.
5826 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5828 * socket.c: Don't include a prototype for inet_aton; just use a
5829 K&R style declaration, to avoid warnings but minimize the chance
5830 of conflicts with the system.
5832 On NextStep, <utime.h> doesn't define struct utime, unless we
5833 #define _POSIX_SOURCE before #including it.
5834 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5835 * acconfig.h: New comment text for above CPP symbol.
5836 * configure.in: Call it.
5837 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5839 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5841 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5842 testing for __EMX__.
5844 * posix.c: #include <libc.h>, if it exists.
5846 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5847 don't even know if the latter exists.
5849 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5850 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5851 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5853 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5855 (scm_init_posix): Use them when initializing the Scheme constants
5858 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5860 * Makefile.in (libdir, includedir, bindir): Use the
5861 autoconf-supplied values, instead of deriving them ourselves.
5862 (pkgincludedir, datadir, pkgdatadir): New variables.
5863 (install, uninstall): Put the header files in a special
5864 subdirectory, not in the main search path.
5866 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5867 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5869 * Makefile.in (IMPLPATH): Deleted; never used.
5871 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5872 on the Tcl/Tk source any more.
5873 (INCLUDE_CFLAGS): Remove references to the above.
5875 * Makefile.in (version.o): Corrected dependencies.
5877 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5879 * libguile.h: #include "version.h"
5881 * init.c (scm_boot_guile): Call scm_init_version.
5882 * gscm.c (gscm_run_scm): Call scm_init_version.
5884 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5885 GUILE_VERSION): AC_DEFINE these.
5886 (acconfig.h): #undef the above symbols.
5888 * Makefile.in (libobjs): Add version.o.
5889 (installed_h_files): Add version.h.
5890 (c_files): Add version.c.
5891 (gen_c_files): Add version.x.
5892 (version.o): New rule.
5893 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5894 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
5895 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
5896 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
5897 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
5898 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
5899 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
5900 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
5901 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
5902 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5903 weaks.o): Add version.h to dependency lists.
5904 (markers.o): Remove duplicate rule.
5906 * version.h: New file.
5908 * version.c: New file.
5910 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5912 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5913 array; use it appropriately. Since GCC is quite happy to
5914 subscript functions, it never warned us about this; we should use
5915 -Wpointer-arith in the future. I guess we never tested
5918 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5920 * socket.c: Doc and copyright fixes.
5922 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5924 * debug.c: Fixed and improved gdb support.
5926 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5928 * socket.c: Added declaration of inet_aton to avoid compiler
5929 warning. (Hope this solution is correct.)
5931 * stime.c: Added declaration of ftime. (This is missing in
5934 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5936 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5938 * Makefile.in (c_files): add strerror.c.
5940 * strerror.c: new file from Emacs' sysdep.c.
5941 maybe configure should also check for sys_errlist.
5943 * configure.in (AC_REPLACE_FUNCS): add strerror.
5945 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5947 * debug.c (scm_init_debug): Added initialization for
5948 scm_evaluator_traps.
5950 * debug.h, debug.c: Various name changes.
5951 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5952 "debug-options-interface". See commentary in options.c.
5954 * options.h, options.c: Options now have documentation strings.
5955 Also added a long explanatory commentary.
5957 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5960 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5961 last_debug_info_frame is now updated in all cases.
5963 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5966 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5968 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5969 Added option STACK_CHECKING.
5971 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5973 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5975 * __scm.h: Removed symbols for debugging support.
5977 * acconfig.h: Added symbols for debugging support.
5979 * configure.in: Added user option for debugging support.
5980 --enable-debug will include the debugging code into libguile.a.
5982 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5983 scm_relocate_chunk_to_heap.
5985 * debug.c: New file: low-level debugging support. It also
5986 includes support for debugging with gdb. (The extensions to gdb
5987 are written by Per Bothner at Cygnus.)
5989 * debug.h: New file: low-level debugging support.
5991 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5992 argument pairs. Extensive modifications to the debugging
5993 evaluator. Added "SECTION:" commentaries to clarify what happens
5994 when, during double compilation. Renamed EVALIMP --> EVALIM.
5995 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5996 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5997 the beginning of the file. New procedure: scm_unmemocopy.
5998 Added some global state variables needed by the debugging
5999 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
6000 check_entry, check_apply, check_exit, debug_options and
6001 evaluator_traps. New acro: undefine.
6003 * eval.h: Renamed EVAL --> XEVAL.
6005 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
6006 --> scm_make_weak_key_hash_table.
6008 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
6009 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
6011 * libguile.h: Conditionally include debug.h
6013 * objprop.c (scm_object_properties, scm_set_object_properties_x):
6014 scm_object_properties shouldn't return handle. `handle' now gets
6015 initialized in scm_set_object_properties_x. scm_object_properties
6016 doesn't any longer create an entry in scm_object_whash.
6018 * options.c: New file: handling of run time options.
6020 * options.h: New file: handling of run time options.
6022 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
6024 * print.c: New procedure: scm_print_options
6026 * print.h: Defines for print options.
6028 * read.c: New procedure: scm_read_options
6030 * read.h: Defines for reader options.
6032 * root.h: Added scm_source_whash among scm_sys_protects.
6034 * srcprop.c: New file: source properties.
6036 * srcprop.h: New file: source properties.
6038 * throw.c (jbsmob): Jump buffers are now correctly allocated.
6039 (Bug found by A. Green.)
6041 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
6043 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
6045 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
6047 * libguile.h: #include "objprop.h"; I guess this was forgotten.
6049 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
6050 and should be called by the final client.
6052 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
6054 * gc.h: Use the PROTO macro when declaring functions.
6055 * gc.c: Use the PROTO macro when declaring static functions.
6056 Remove the CPP hair around function definitions.
6058 * gc.c (scm_init_storage): Initialize scm_asyncs.
6060 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
6061 preprocessor symbol; "__scm.h" is where it might get #defined.
6062 * __scm.h: Similar: #include <scmconfig.h> before testing
6065 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
6067 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
6069 * init.c (scm_boot_guile): Add init_func argument; call
6070 (*init_func) instead of calling scm_appinit; it's ucky to
6071 hard-code names for the user's procedures.
6072 * init.h (scm_boot_guile): Adjust declaration.
6074 * __scm.h (PROTO): New macro, for declaring functions with
6077 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
6078 eliminate all the __STDC__ conditionals.
6079 (scm_boot_guile): Add declaration.
6080 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
6081 Remove __STDC__ conditionals around function definitions; the
6082 declarations in init.h will provide the same information, more
6085 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
6086 complain about it in the error message; the error message is
6087 adequate without that note, and there's nothing the user can do
6090 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
6092 * Makefile.in (ancillary): Drop def.sed.
6094 * posix.c (scm_init_posix): Use numeric values, rather than
6095 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
6096 F_OK. The symbols aren't available on some systems, and I'm
6097 pretty sure their values are fixed by common widespread practice.
6098 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
6100 More functions unavailable on some systems.
6101 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
6102 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
6104 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
6105 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
6106 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
6107 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
6108 stub that signals an error as the #else.
6110 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
6112 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
6114 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
6116 * unif.c: include ramap.h.
6118 * read.c (endif): case_insensative_p renamed case_insensitive_p.
6120 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
6122 * ports.c: include sys/ioctl.h.
6124 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
6126 * configure.in: check for sys/ioctl.h.
6128 * ports.c: include <malloc.h> not "malloc.h".
6130 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6132 * fports.c: remove ttyname and tmpnam declarations.
6134 * posix.c: fewer ttyname declarations.
6136 * fports.c: include <string.h> not "string.h".
6138 * init.c, ioext.c: include string.h and unistd.h.
6140 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6142 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
6143 genio.c, simpos.c, vports.c: include string.h.
6145 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
6147 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
6149 (scm_addr_buffer_size): change type from scm_sizet to int.
6150 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
6151 from scm_sizet to int.
6153 * error.c: include unistd.h.
6155 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
6158 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
6160 * __scm.hd, def.sed: deleted.
6162 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
6164 Changes for NeXT, suggested by Robert Brown.
6165 * configure.in: Call AC_TYPE_MODE_T.
6166 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
6167 NeXT. Put header file list in alphabetical order.
6168 * configure, scmconfig.h.in: Regenerated.
6169 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
6171 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
6174 * acconfig.h: New file, providing documentation for the CPP
6175 symbols defined in configure.in
6176 * acconfig-1.5.h: Removed; superceded by the above.
6178 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
6180 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
6182 * fports.c (scm_open_file): don't return #f, throw error.
6184 * ioext.c (fileno): renamed from %fileno.
6185 (soft-fileno): deleted.
6187 * ports.c (scm_port_revealed): don't need to check for -1 from
6189 (scm_set_port_revealed_x): return unspecified, not #f.
6191 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
6193 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
6195 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
6197 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
6199 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
6201 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
6202 This is necessary on Ultrix, and doesn't hurt portability.
6204 * Makefile.in (dist-dir): New target, implementing a new dist system.
6205 (installed_h_files): Put in alphabetical order.
6206 Remove duplicate entries for markers.h and unif.h.
6207 (c_files): Remove duplicate entries for markers.c.
6208 (ancillary): Renamed from anillery; all uses changed. Remove
6209 PLUGIN; it's a directory, and needs special treatment in dist-dir.
6210 Remove all the ../doc/* files; doc/Makefile.in handles that.
6212 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
6214 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
6215 every if must have an else, or else the whole command has a
6216 non-zero exit code whenever the if's condition is false.
6218 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
6220 * posix.c: include string.h.
6222 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
6224 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
6227 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
6228 Remove leading % from scheme names.
6229 Do not return error values, call SCM_SYSERROR or similar.
6231 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
6233 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
6235 * struct.c (scm_init_struct): new file.
6237 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
6239 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
6240 (scm_list_head): added list-head for rapidly chopping argument
6241 lists off of longer lists (and similar).
6243 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
6245 * objprop.c (scm_object_property): assq the cdr of the whash
6246 handle for obj, not the handle itself.
6248 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
6250 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of

6294 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
6296 * ports.c: removed functions relating to the mapping between ports

6305 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
6306 handled correctly (SCM_FREEP was applied to them) -- test for
6307 NIMP. Keys in weak hash tables were spuriously (though harmlessly)

6362 * ports.c (scm_add_to_port_table): Added fields
6363 to port table entries: file_name, line_num, col.

6475 initialization to fix a race condition.
6477 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

6501 set the multi_byte flag correctly in symbols. This is wrong.
6502 intern_obbary_soft and msymbolize should take an extra parameter.
6503 Also, weird multibyte symbols don't print correctly.
6504 The weird symbol syntax is also a bit bogus (emacs doesn't quite
