1 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3 * backtrace.c (get_applybody): Help function which lookups the
4 first body form of the apply closure.
5 (display_error_body): Prevent the source of the first form of the
6 apply closure from being printed in error messages.
8 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
9 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
11 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
13 * stacks.c (read_frame): Bugfix: Removed lingering `else'
15 (read_frames): Use SCM_MACROEXPP.
17 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
19 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
20 don't contain interesting information since all arguments are
21 present in the frame which applies the compiled closure anyway.);
22 Skip the transformer application frames.
24 * print.c (scm_iprin1): Print gsubrs as primitives.
26 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
28 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
30 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
31 that we can identify these in a backtrace. (This change doesn't
32 introduce any significant speed penalty.)
34 * eval.c: Added note about `serial-map' using scm_map.
36 * read.c, read.h (scm_read_options, scm_read_opts): Removed
37 readline options. They should reside in their own options array.
39 * readline.c, readline.h (scm_readline_options,
40 scm_readline_opts): Moved readline options here.
42 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
44 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
45 SCM_ROCHARS instead of SCM_CHARS.
47 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
48 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
50 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
52 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
53 This is quite important since the latter clears the
54 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
55 every single character read...
57 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
59 * print.c (scm_iprin1): Removed suspect looking (and indeed
60 malevolent) semicolon after test for user supplied closure print
61 procedure. (Thanks to Telford Tendys.)
63 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
64 (scm_memq, scm_memv, scm_member): Do argument checking *before*
65 starting to search the list. Removed call to sloppy_mem_check.
67 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
68 procedures: Same as scm_delq_x et al, but delete maximally one
71 * options.c (scm_options, scm_init_options): GC-protect option
72 values of type SCM. (Thanks to Telford Tendys.)
74 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
76 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
77 make sure that there always is a "real" scm_lookupcar.
79 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
81 * read.c, read.h (history-length, history-file): New read options.
82 (scm_read_options): Stifle history to history length.
84 * readline.c (scm_read_history, scm_write_history): New
87 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
89 * eval.h (scm_macro_eval_x): Removed declaration.
91 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
92 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
93 Renamed and made global.
95 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
96 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
98 * evalext.c, evalext.h: New files. Contain non-R5RS things
99 having to do with evaluation.
101 * evalext.c (scm_serial_map): New procedure: Version of `map'
102 which guarantees that the procedure is applied to the lists in
104 (scm_m_sequence_to_list): New syntax: Version of `begin' which
105 returns a list of the results of the body forms instead of the
106 result of the last body form.
107 (scm_definedp, scm_m_undefine): Moved from eval.c
109 * evalext.h (scm_m_sequence_to_list): Added declaration.
111 * macros.c, macros.h: New files.
112 (scm_procedure_to_syntax, scm_procedure_to_macro,
113 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
114 scm_macro_name, scm_macro_transformer): Moved from eval.c
115 (scm_make_synt): Moved from eval.c
117 * procs.c, procs.h (scm_procedure_documentation): Moved from
120 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
123 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
125 * debug.c, print.c: Added #include "macros.h".
127 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
129 This change adds the ability to use `unread-char' multiple times
130 without interspersed reads and adds the new procedure
131 `unread-string'. The change is optimized for the common case of
132 unreading a single character. This is also the reason behind the
133 choice to store characters in the port itself: in most cases no
134 extra malloc is required.
136 The amount of code in some macros in ports.h has been increased to
137 the extent that they would fit better as C functions, but, since
138 this code belongs to the port representation, such functions
139 should be placed in ports.c which would cause calls back and forth
140 between ports.c and genio.c. That is not good for performance.
141 Also, keeping them as macros allows the compiler to do some
142 optimizations which are needed to make the current interface
143 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
145 One benchmark (Guile startup time) indicates an increase of
146 loading speed of 1%. Another (reading (using `read') boot-9.scm
147 10 times) shows no change in performance.
149 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
150 made to find a beautiful solution.)
152 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
153 (SCM_TRY_CLRDY): New macro: Only clear the first unread
154 character. (SCM_CLRDY clears all.)
155 (SCM_N_READY_CHARS): New macro: Returns number of unread
156 characters in a port. Returns wrong answer if SCM_CRDYP is false.
157 (struct scm_port_table): New fields: `entry' contains port table
158 index, `cp' points to last unread char, `cbuf' is the buffer for
159 unread chars, `cbufend' points after end of the character buffer.
161 * ports.h, ports.c (scm_unread_string): New procedure.
162 (scm_grow_port_cbuf): New function.
164 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
166 (scm_generic_fgets), fports.c (local_fgets): Use a loop
167 to read unread characters. Use SCM_TRY_CLRDY instead of
170 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
172 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
174 * genio.c, genio.h (scm_ungets): New function.
176 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
179 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
181 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
182 declarations. (Thanks to Russ McManus.)
184 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
186 * numbers.c (num2long): As a software archeologist, I'm proud of
187 this finding! :) Preliminary dating suggests an almost 4 year old
188 remnant from the SCM ancestor. The sample has been removed from
189 the finding site and is now safely stored in the repository.
191 * numbers.h: Removed prototype for num2long.
193 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
195 * gh_data.c (gh_scm2doubles): Make it possible to pass result
197 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
198 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
199 * gh.h: Updated and added prototypes.
201 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
203 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
205 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
207 * guile-snarf.in: Never generate an empty file. (Thanks to
210 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
211 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
212 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
213 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
214 gh_new_procedure5_0): Specify argument types, to appease C++
215 compilers. (Thanks to Brad Bowman.)
217 Bug reports from Russ McManus:
218 * guile-snarf.in: If the CPP environment variable is set, use that
219 as the C preprocessor, instead of the preprocessor autoconf
221 * snarf.h (SCM_PROC): Cast the function pointer passed to
222 scm_make_gsubr, to satisfy C++.
224 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
225 Use the handler passed, instead of ignoring it and using
226 gh_standard_handler. (Thanks to Etienne Bernard.)
228 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
230 * ports.h: Put text after #endif in comment. (Thanks to Nicolas

253 * script.c (scm_compile_shell_switches): Define
254 use-emacs-interface in the root module, so the repl code can see
255 it. See today's change to top-repl in ice-9/boot-9.scm.
257 * filesys.c (set_element, get_element): Make sure that `element'
258 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
259 Boekemeier and Jorgen "forcer" Schaefer.)
261 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
263 * chars.c (scm_charnames): In ASCII character name table, make
264 newlines print as #\newline by default, not #\nl.
266 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
267 alphabetical order. Oh thrills. But it helps me know how far
268 along in the compilation I am.
269 * Makefile.in: Regenerated.
271 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
273 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
274 #bytes(...) to #y(...), and syntax for short vectors from
275 #short(...) to #h(...). This may seem nutty, but, like the other
276 uniform vectors, byte vectors and short vectors want to have the
277 same print and read syntax (and, more basic, want to have read
278 syntax!). Changing the read syntax to use multiple characters
279 after the hash sign breaks with the conventions used in R5RS and
280 the conventions used for the other uniform vectors. It also
281 introduces complexity in the current reader, both on the C and
282 Scheme levels. (The Right solution is probably to change the
283 syntax and prototypes for uniform vectors entirely.)
285 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
287 Don't use local_fgets on sockets; ftell doesn't work on sockets.
288 (Thanks to Jorgen "forcer" Schaefer.)
289 * ports.h (SCM_NOFTELL): New flag.
290 * fports.c (local_fgets): If it's set, use the generic fgets.
291 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
293 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
295 * script.c (scm_compile_shell_switches): Add handling of -q switch
296 (inhibit loading of user init file).
297 (scm_shell_usage): Add usage text for -q switch.
298 (scm_compile_shell_switches): Always load user init file first if
301 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
303 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
304 and is now broken under NetBSD. I can't fathom what it's trying
305 to do, so I've replaced it with something that I do understand,
306 which seems to work, and which isn't broken on NetBSD. "Progress?
307 You Decide." (Thanks to Perry Metzger.)
309 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
310 signed/unsigned comparison.
312 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
314 Warning fixes from Greg Harvey:
315 * unif.c (scm_array_set_x): initializer for pos
316 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
317 * struct.c (scm_struct_ref, scm_struct_set_x): Added
318 initializers for field_type, since EGCS so desparately wants to
320 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
321 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
322 when GUILE_DEBUG is defined.
323 * dynwind.h (scm_wind_chain): Same.
324 * ports.h (scm_pt_size, scm_pt_member): Same.
325 * print.h (scm_current_pstate): Same.
326 * procs.h (scm_make_cclo): Same.
328 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
330 Handle short and long long uniform arrays properly. (Thanks to
332 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
333 raeql_1): Add cases for scm_tc7_svect (short vectors) and
334 scm_tc7_llvect (long long vectors).
336 Change the way libguile and boot-9.scm are timestamped, to try to
337 get rid of these spurious mismatch warnings. Now both
338 libguile/versiondat.h and ice-9/version.scm are generated directly
339 by the configuration process, rather than having version.scm
340 generated directly, and libguile/versiondat.h generated by the
341 Makefile, which is generated by configure. It seems that
342 sometimes the Makefile would change, but versiondat.h depends on
343 Makefile.in, not Makefile, so it wouldn't get rebuilt.
344 * Makefile.am (versiondat.h): Target removed; this is generated
345 directly by the configure script now.
346 (BUILT_SOURCES): Remove versiondat.h.
347 * versiondat.h.in: New file, transformed by the configure script
349 * Makefile.in: Regenerated.
351 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
352 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
353 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
354 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
355 if we want to use them in a header file some day, we can. (Thanks
358 * stime.c (scm_get_internal_real_time): Do the arithmetic using
359 SCM numbers, so we won't have rollover problems; the range of a
360 signed long in milliseconds is about 25 days. (Thanks to Karl
363 Don't redefine sleep and usleep; fix this problem now.
364 * coop.c (sleep, usleep): Remove declarations; we don't use or
365 redefine these any more.
366 (scm_thread_usleep, scm_thread_sleep): New functions which do the
367 job of usleep and sleep in a thread-friendly way. We can use
368 these in the rest of Guile. Define versions for systems both with
370 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
371 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
372 we're just using it, not redefining it, we can use a K&R style
374 (sleep): Declare this, too, if the system hasn't.
375 (scm_sleep, scm_usleep): Use scm_thread_sleep and
376 scm_uthread_sleep if they're available; otherwise, just call the
378 * scmconfig.h.in: Regenerated.
380 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
382 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
384 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
386 * threads.c: Doc fix.
388 The argument type of usleep varies from system to system,
389 as does the return type. We really shouldn't be redefining usleep
390 at all, but I don't have time to clean that up before the 1.3.
391 release. It's on the schedule for afterwards. (Thanks to Julian
393 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
395 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
396 * scmconfig.h: Regenerated.
398 * simpos.c (scm_software_type): Procedure deleted. This isn't the
399 right way to handle system variation. Autoconf's approach is the
401 * simpos.h (scm_software_type): Declaration deleted.
403 * script.c (scm_find_executable): Don't test if unix is #defined
404 here; first, NetBSD doesn't #define it, and second, it's the wrong
405 way to go about these things. (Thanks to Perry Metzger.)
406 (dld_find_executable): Delete this MSDOS support code. This isn't
407 the way we want to support this; it needs to be rethunk at a
410 * genio.c (scm_do_read_line): Don't just politely check that the
411 line was either non-empty or EOF. Abort if it's empty and not
414 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
416 * scmconfig.h.in: Regenerated.
418 * libguile.h: Don't omit the dynamic linking functions. (Thanks
421 * genio.c (scm_do_read_line): Count lines correctly when the file
422 doesn't end in a newline.
424 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
426 * genio.c (scm_do_read_line): Maintain the line count correctly.
427 (Thanks to Harvey J. Stein and Greg Harvey.)
429 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
432 * numbers.c (big2str): Protect t from garbage collection until
433 we're done. (Thanks to Gary Houston.)
435 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
437 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
439 * Makefile.in: Regenerated.
441 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
442 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
445 Do magic to mix reads and writes on stdio FILE-based ports.
446 (Thanks to Christian Lynbech.)
447 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
449 (pre_read, pre_write): New functions.
450 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
451 local_fputs): Call them.
452 (local_fflush): Mark the port as ready for reading and writing.
453 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
454 flags on new port objects. This might not be accurate --- who
455 knows what state the FILE * is in when we get it --- but it won't
456 do extraneous calls to fflush or fseek, so it's no worse than the
457 behavior before this change.
458 * ports.h: Add comment.
460 Centralize the creation of port objects based on stdio FILE * in
461 fports.c; don't just throw them together anywhere.
462 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
463 what the rest of Guile wants. Don't set the revealed count;
464 that's only appropriate for stdin, stdout, stderr.
465 (scm_standard_stream_to_port): This function does set the revealed
467 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
468 not scm_stdio_to_port.
469 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
470 * fports.c (scm_open_file): Same.
471 * posix.c (scm_pipe): Same.
472 * socket.c (scm_sock_fd_to_port): Same.
473 * ioext.c (scm_fdopen): Same.
474 (scm_freopen): Moved from here to...
475 * fports.c (scm_freopen): ... here. This is really something that
476 munges the internals of an fport, so it should go here.
477 * fports.h (scm_stdio_to_port): Adjust prototype.
478 (scm_standard_stream_to_port, scm_freopen): New protoypes.
479 * ioext.h (scm_freopen): Prototype removed.
481 * filesys.c (set_element, get_element): This can work on both pipe
482 and file ports, so use SCM_FPORTP to typecheck, instead of testing
485 * scmconfig.h.in: Regenerated.
487 Change the definition of the functions in scm_ptobfuns so that
488 they get passed the port object, not the port's stream.
489 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
490 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
491 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
492 Pass the port itself to the scm_ptobs function.
493 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
494 scm_generic_fgets): Same.
495 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
496 getc_void_port, fgets_void_port, close_void_port): Just change the
497 argument names; these functions don't really do anything.
498 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
499 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
500 port as an argument, and use SCM_STREAM to get the stdio FILE *.
501 Also, use prototyped definitions, and get rid of the extra
503 (scm_fptob, scm_pipob): We don't need casts here any more.
504 * strports.c (prinstpt): Use prototype declarations.
505 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
506 and use SCM_STREAM to get the string info. Also, use prototyped
507 definitions, and get rid of the extra declarations.
508 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
511 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
512 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
514 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
515 scm_fgets, for consistency.
516 (scm_fptop, scm_pipob): References updated.
518 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
520 Include the source location in error messages for scripts.
521 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
522 stack is still there when we catch the error.
523 * throw.c (handler_message): If we are handling an error with a
524 message, then put together the proper arguments and call
525 scm_display_error, instead of scm_display_error_message. That
526 displays source location, if it can find it.
528 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
530 * gc.c (scm_unprotect_object): Change this so that calls to
531 scm_protect_object and scm_unprotect_object nest properly.
532 (scm_protect_object): Doc fixes.
534 * strings.c (scm_string_set_x): Require the argument to be a
535 writable string, not a substring or a symbol.
536 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
537 (Thanks to John Redford and Charbel Jacquin.)
539 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
541 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
543 * eval.c (safe_setjmp): Remove this misunderstanding.
544 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
547 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
549 * libguile.h: Mark these as C declarations, for compilation by C++
552 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
553 __cplusplus clause. I seriously doubt this ever worked the way
554 the author seems to have intended.
556 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
558 Utterly needless cleanups to hopelessly messy code.
559 * ports.c: Doc fixes.
560 (scm_fflush): Moved to ...
561 * genio.c (scm_fflush): ... here, amongst all the other port
562 method invocation functions.
563 * genio.h, ports.h: The prototype moves too.
565 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
567 * backtrace.c (display_error_body): The current frame does not
568 always have a parent frame; consider a function called directly
569 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
572 * alloca.c (alloca): Undo yesterday's changes, and simply call
573 malloc directly for storage, and abort if we don't get what we
574 want. The situation is much simpler --- just call malloc. Emacs
575 has bizarre/evil requirements (signal handlers might malloc unless
576 you set this global flag, so you have to set the flag around all
577 calls to malloc) which we are certainly not going to conform to,
578 so we can do the simple and obvious thing.
580 * coop.c (coop_condition_variable_wait): Make this function
581 static. It's only useful internally --- you should never just
582 wait on a condition variable.
583 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
585 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
587 * unif.c (scm_array_set_x): Accept any kind of number as an
588 element for a uniform vector of doubles. This is more consistent
589 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
591 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
592 works; I can't conveniently test it myself. (Thanks to Dvid
593 Tillman for the bug report.)
597 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
598 from here, not from scm_compile_shell_switches (which is a pretty
599 dumb place to do it).
600 (scm_load_startup_files): New function.
601 (scm_ice_9_already_loaded): Variable moved to here from script.c.
602 * script.c (scm_compile_shell_switches): Don't load the startup
604 (scm_ice_9_already_loaded): Variable moved.
605 * init.c (scm_load_startup_files): Prototype for new function.
606 * gh_init.c (gh_enter): Doc fix.
608 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
610 Some anti-warning changes from Greg Harvey.
611 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
612 warnings when it doesn't understand our NORETURN declarations in
614 * posix.c (scm_mknod): Similar.
616 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
618 * posix.c (scm_getpwuid): If we can't find an entry, return our
619 own message, instead of using scm_syserror --- the getpwMUMBLE
620 functions don't set `errno' to anything interesting.
622 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
624 Get rid of warnings from the cooperative threading system.
625 * threads.h (scm_single_thread_p, scm_yield,
626 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
627 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
628 scm_wait_condition_variable, scm_signal_condition_variable): Add
629 prototypes for these Scheme-visible functions.
630 * coop-defs.h (coop_next_runnable_thread,
631 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
632 Prototypes for these here, even though they're from iselect.c.
633 (coop_condition_variable_wait, coop_join): Add prototypes.
634 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
635 scm_threads_free_condvar): Make these smob functions static.
636 * coop-threads.h (coop_init): Give this a real prototype.
637 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
638 (coop_next_runnable_thread): No need to provide prototype; it's in
641 * scmconfig.h.in: .detarenegeR
643 * iselect.c, threads.c: Doc fixes.
645 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
647 * Makefile.in: Regenerated with a patched automake, to get
648 dependency generation right when using EGCS.
650 * inet_aton.c (inet_aton): Add prototype, to remove compiler
651 warning. (Thanks to Robert Pluim.)
653 * inet_aton.c (inet_aton): Reassure the compiler that the
654 arguments to the <ctype.h> macros are all unsigned characters, not
657 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
659 Getting rid of more warnings...
660 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
661 today's change to ../configure.in.
662 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
663 * scmconfig.h.in: Regenertaded.de.,.__
664 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
665 (scm_localtime, scm_mktime): Use a const char * to manipulate the
668 * readline.c: Doc fix.
669 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
670 * readline.h (scm_filename_completion_function): Add prototype.
671 (scm_init_readline): Make this into a prototype.
673 * readline.c (scm_filename_completion_function): Use SCM_PROC to
674 declare this, instead of calling scm_make_subr manually.
676 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
678 * readline.h (scm_init_readline): Add prototype for this.
679 (scm_init_readline): Make this a real prototype.
681 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
683 Warning fixes from Maciej Stachowiak:
684 * backtrace.h (scm_display_application, scm_backtrace): Add
686 * debug.c (scm_m_start_stack): Make this function static.
687 * fluids.h (scm_fluid_p): Add prototype.
688 * procprop.c (scm_i_procedure_arity): Make this function static.
689 * regex-posix.c (scm_regexp_error_msg): Make this function static.
690 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
691 * root.h (scm_dynamic_root): Add external prototype.
692 * scmsigs.h (scm_usleep): Add external prototype.
693 * script.h (scm_init_script): Use prototype, not K&R decl.
694 * stacks.h (scm_stack_id): Add external prototype.
695 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
697 1998-09-30 Mark Galassi <rosalia@cygnus.com>
699 * gh.h: took out the definitions of vset and vref, since they are
700 replaced by the proper vector routines that correspond to the R4RS
703 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
705 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
706 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
707 third argument, a C expression that should result in a SCM value,
708 which is used to initialize the variable. Reimplemented
709 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
712 * version.h (scm_libguile_config_stamp): Add prototype.
713 (From Maciej Stachowiak.)
715 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
717 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
718 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
720 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
722 * print.c (scm_iprin1): Rather than having one i, and using it in
723 several places, declare a fresh i local to each block where it is
724 used, and give it a signedness appropriate to its use in each case.
727 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
730 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
731 signed/unsigned clashes.
733 * posix.h (scm_tmpnam): Added prototype.
735 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
736 scm_make_subclass_object): Add external prototypes.
738 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
739 comparison is okay here.
741 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
743 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
744 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
746 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
749 * load.c (swap_port): Make this function static.
751 * load.c (scm_search_path): Make max_path_len and max_ext_len
752 unsigned, since they're compared against string sizes.
754 * load.c (init_build_info): Make i unsigned.
756 * ioext.h (scm_read_line): Add prototype.
758 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
759 scm_hash_fn_remove_x): Make hash bucket index local variable k
760 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
761 accurately as possible.
763 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
764 comparisons, and range checking to make sure those casts are
767 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
768 signed/unsigned comparisons.
770 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
771 avoid signed/unsigned comparisons.
772 * smob.h (scm_numsmob): Change extern declaration to match.
774 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
775 avoid signed/unsigned comparisons.
776 * ports.h (scm_numptob): Change extern declaration to match.
777 (scm_current_load_port, scm_set_port_line_x,
778 scm_set_port_column_x): New prototypes.
780 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
781 test code, and it causes warnings.
783 * gh.h (gh_int2scmb, gh_uniform_vector_length,
784 gh_uniform_vector_ref): Added prototypes.
786 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
787 debugging support unconditionally. That's backtrace.c, stack.c,
788 debug.c, and srcprop.c.
789 (EXTRA_libguile_la_SOURCES): Omit those from here.
790 * Makefile.in: Regenerated.
792 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
794 * options.c (scm_options): Bugfix: Allow empty list of options!
796 * debug.c, debug.h (scm_single_step): Removed.
797 (scm_with_traps): New procedure. This procedure could easily be
798 written in Scheme but needs to be highly optimized.
800 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
802 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
803 Check SCM_TRAPS_P before trapping.
805 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
807 Changes to avoid signed/unsigned comparison warnings.
808 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
809 (scm_gc_sweep): Make n and j local to the blocks they're used in,
810 so they can have appropriate types for each application. Make i
811 signed. Use initializers in some spots. I'll probably pay for
813 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
814 (scm_must_realloc): Make nm unsigned.
815 (init_heap_seg): Make new_seg_index and n_new_objects signed.
816 (scm_init_storage): Use prototype-style definition, and make the
818 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
819 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
821 * filesys.c (scm_readlink): Make local vars rv and size ints, to
822 avoid signed/unsigned comparison warnings, and because the return
823 value of readlink may be -1. Don't bother casting the third
824 argument to readlink.
826 * filesys.c (scm_dirname, scm_basename): Move these to their own
827 page, at the end of the file.
828 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
830 * eval.h (scm_eval_options_interface): Add external prototype for this.
831 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
833 * eval.c (scm_lookupcar1): Make this static.
835 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
836 Make these prototype declarations, not K&R-style.
838 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
839 unsigned comparison warning.
841 * appinit.c: File removed. It had a single function in it, empty,
842 whose reason for existence is explained in no documentation or
843 comment. I think it's there as a default for some Tcl-style
844 initialization, but Tcl abandoned that approach a while ago.
845 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
846 (BUILT_SOURCES): Remove appinit.x.
847 * Makefile.in: Regenerated.
849 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
851 * Makefile.in: Regenerated using the last public version of
852 automake, not the hacked Cygnus version.
854 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
856 Remove Totoro kludge.
857 * Makefile.in, scmconfig.h.in: Regenerated.
858 * init.c, readline.c: Don't check if TOTORO is #defined.
860 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
862 * Makefile.am: Adjust for new thread configuration system.
863 (INCLUDES): Include the value of THREAD_CPPFLAGS.
864 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
866 (THREAD_LIBS): Definition deleted; automake will generate such
867 things automatically.
868 * Makefile.in: Regenerated.
870 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
872 Simplify smob and port marking; set the mark bit in the generic
873 marking code, and make marker routines only responsible for
874 turning up outgoing pointers.
875 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
876 before calling the marking function. Don't call the marking
877 function if it's zero.
878 * markers.c (scm_mark0): Just return #f. This function isn't
879 necessary at all now, but it's harmless to call it. We'll leave
880 it in so other folks' code doesn't croak at link time.
881 (scm_markcdr): Don't call SCM_SETGC8MARK.
882 * async.c (mark_async): Don't call SCM_SETGC8MARK.
883 * dynl.c (mark_dynl_obj): Same.
884 * root.c (mark_root): Same.
885 * srcprop.c (marksrcprops): Same.
886 * unif.c (markra): Same.
887 * variable.c (scm_markvar): Same.
888 * ports.c (scm_markstream): Same.
889 (void_port_ptob): Specify zero for our marking function.
890 * debug.c (debugobjsmob): Same.
891 * dynwind.c (guardsmob): Same.
892 * filesys.c (dir_smob): Same.
893 * fluids.c (fluid_smob): Same.
894 * fports.c (scm_fptob, scm_pipob): Same.
895 * mallocs.c (mallocsmob): Same.
896 * regex-posix.c (regex_t_smob): Same.
897 * smob.c (freecell, flob, bigob): Same.
898 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
899 * throw.c (jbsmob, lazy_catch_funs): Same.
901 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
903 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
904 scm_copy_tree on code in order not to let memoized code to leak
905 out. Thus, scm_copy_tree needs to copy vectors as well since
906 quasiquote can introduce evaluated code also inside vector
909 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
911 * eval.c (scm_copy_tree): Removed ability to copy vectors.
913 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
914 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
917 * unif.c: Say that ivect and uvect are of type signed and unsigned
918 long instead of int in commentary so that it correctly describes
921 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
923 * stime.c: Removed declaration of strptime. (It should be
924 declared by the system headers. If it turns out that some systems
925 don't, we'll handle that then.) (Thanks to Greg Troxel.)
927 * stime.h: Renamed TIMEH --> STIMEH
929 * backtrace.c (scm_display_error, scm_display_backtrace): In order
930 to increase portability, don't use structure assignment.
931 (Thanks to Nicolas Neuss.)
933 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
935 (finalize_fd_sets): Added empty statement after last case label.
936 (Thanks to Nicolas Neuss.)
938 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
941 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
943 * init.c, readline.c: OK, I won't have these readline.x bug
944 reports anymore. We've had them since April. The current reason
945 is a completely unintelligible failure of totoro.red-bean.com to
946 do the test for rl_getc_function in libreadline correctly. This
947 kludge overrides the test if we're on totoro so that the snapshot
948 generation process can work.
950 * readline.c: Define a strdup replacement if not existent on system.
952 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
954 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
955 This change makes scm_make_vector R5RS compatible. We cannot keep
956 the third argument since people want to be able to deduce the form
957 of the C function call only by looking at R5RS. (At the same time
958 we have removed some unnecessary complexity!)
960 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
961 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
962 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
963 argument in call to scm_make_vector.
965 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
967 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
968 This macro is useful in applications.
970 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
972 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
973 (scm_parse_path, scm_search_path): New Scheme level procedures.
975 * load.h (scm_internal_parse_path, scm_parse_path,
976 scm_search_path): Declared.
978 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
980 * filesys.c (dirname, basename): New procedures.
982 * init.c (scm_boot_guile_1): Removed condition around
985 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
986 new data type (guards) for representation of C level guards and
987 data on the wind chain.
988 (scm_internal_dynamic_wind): New function.
990 * dynwind.h: Declare scm_internal_dynamic_wind.
992 * root.h (scm_root_state): Added scm_cur_loadp.
994 * root.c (mark_root): Added comment about cur_loadp.
996 * load.c: #include "dynwind.h";
997 (scm_primitive_load): Use scm_inner_dynamic_wind to update
1000 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
1002 * ports.c (current-load-port): New procedure.
1004 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1006 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
1007 not a tty, return #f.
1009 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
1010 to Julian Satchell and Roland Kaufmann.)
1012 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
1013 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
1015 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1017 * debug.h, debug.c (scm_start_stack): New function. Implements
1018 the guts of old scm_m_start_stack.
1020 * debug.c (scm_m_start_stack): Use scm_start_stack.
1022 * init.c (scm_start_stack, scm_restart_stack): Renamed to
1023 start_stack and restart_stack. (These have static scope.)
1025 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1027 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
1028 readline functions to come in release 2.3. (Thanks to Chet
1030 (handle_errors): Use the above functions.
1032 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1034 * readline.c: Improvements for readline support: Handle errors
1035 better; Implement before-read-hook.
1037 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1039 * init.c (scm_boot_guile_1), readline.c: Test for
1040 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
1041 assure that we have version >= 2.1.)
1043 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
1045 * readline.c (scm_readline): Defer interrupts while we're calling
1048 * readline.c (scm_add_history): Bugfix: Do strdup before giving
1049 away the string to add_history.
1050 (completion_function): Do completion for readline. (Thanks to
1052 (scm_filename_completion_function): New procedure: Filename
1054 (current_input_getc): New function. Use this one instead of
1055 standard getc from readline.
1057 * throw.c, throw.h (scm_handle_by_throw): New function: This
1058 handler throws errors to next handler on the dynwind chain.
1060 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
1062 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
1065 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1067 * procprop.c (scm_i_procedure_arity): New function. Returns arity
1069 (scm_procedure_properties): Modified to return arity together with
1071 (scm_procedure_property): Added the read-only property `arity'.
1072 (scm_set_procedure_property_x): It is an error to set the `arity'
1075 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
1076 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
1078 * procprop.h (scm_sym_arity): New symbol.
1080 * objects.c (scm_set_object_procedure_x): New procedure: Use this
1081 to set the dispatch procedure of an operator or entity object.
1083 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
1084 Made procedure slots read-only.
1086 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
1087 scm_tcs_cons_gloc case in zero args switch; Fixed args
1088 construction for operators in scm_tcs_cons_gloc case in two args
1091 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1093 * fluids.c: Removed use of assert.h (in order to avoid
1096 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
1098 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
1100 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
1101 change makes the evaluator safer at the cost of evaluation speed.
1102 It handles the case when the user has added a non-immediate
1103 improper end of the application form, e.g., `(+ 0 . x)'.
1104 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
1105 minimize the extra cost as much as possible. The new code is
1106 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
1107 problem with structs planted directly in the code (e.g. by a
1108 macro). This no longer causes segmentation fault. (Thanks to
1111 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
1112 arg `proc' in order to be able to throw errors; New argument
1115 * Removed extra #include "debug.h"
1117 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
1119 * scmsigs.c: Declare usleep as returning void on some systems.
1120 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
1123 * coop.c (usleep): Return void on some systems.
1125 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1127 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
1129 * coop.c: Changed return type of usleep to int.
1131 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
1132 isn't found in the OS.
1134 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
1135 isn't enabled. (Thought that I had made this change ages ago...)
1137 * iselect.c: Declare bzero if not defined by OS.
1139 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1141 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
1142 condition. (Thanks to John Tobey.)
1144 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
1145 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
1148 * __scm.h: Start the long-term project of moving to POSIX threads.
1149 Phase 1: Classification of all critical sections.
1150 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
1151 for A sections. (See comments in __scm.h for details.)
1153 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
1154 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
1156 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1158 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
1159 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
1160 (libpath.h, versiondat.h): Replaced dependency on Makefile with
1161 dependencies on $(srcdir)/Makefile.in
1162 $(top_builddir)/config.status in order to avoid circularity.
1164 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
1165 from argc if argc was 0 initially.
1167 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
1168 in generation of libpath.h.
1170 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
1172 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
1173 libguile from 2 to 3.
1175 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
1177 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
1179 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
1181 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
1182 scm_set_port_column_x, scm_port_filename,
1183 scm_set_port_filename_x): Removed optional arguments. Added
1184 proper argument checking.
1186 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
1187 stack size in machine words.
1189 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
1190 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
1191 to Ole Myren Röhne.)
1193 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
1195 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
1196 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
1198 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
1201 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
1202 procedure apply: Copy argument lists before pushing them unto the
1203 environment so that the environment won't get mutated due to
1204 manipulation of procedure arguments. This should perhaps be
1205 regarded as a temporary solution until someone finds a more
1206 efficient one. (Thanks to Maciej Stachowiak.)
1208 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
1210 * script.c (scm_compile_shell_switches): Use "guile" as default
1211 zero arg if argc is NULL.
1213 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
1215 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
1216 is zero. (Thanks to Dirk Herrmann.)
1218 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
1220 * ports.c (scm_add_to_port_table): First line is now line 0
1221 (was 1). (Interface changed according to suggestion by Per
1224 * backtrace.c (display_header): Add 1 to line and column numbers
1225 when presenting them to the user.
1227 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
1228 from debug.c --> eval.c
1230 * eval.h, eval.c (scm_eval_options_interface): New options
1232 (SCM_EVAL_STACK): New option: Size of newly created stacks,
1233 i.e. stacks for new threads.
1235 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
1237 * eval.c (unsafe_setjmp): Removed with #if 0.
1239 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
1242 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
1243 to avoid compiler warnings.
1245 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
1247 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
1249 * throw.c (handler_message): Print message on current error port
1250 instead of default error port. (Thanks to Maciej Stachowiak.)
1252 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
1254 * ports.c (scm_add_to_port_table): allocate in units of
1255 struct scm_port_table *, not struct scm_port_table.
1256 * posix.c (scm_close_pipe): remove the port from the port table
1258 Thanks to Rob Engle for both fixes.
1260 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1262 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
1263 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
1265 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1267 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
1269 * backtrace.c (display_error_body, display_backtrace_body),
1270 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
1271 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
1272 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
1273 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
1276 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
1277 don't receive the jmpbuf arg anylonger.
1278 (scm_catch): Don't accept a #f tag.
1279 (scm_throw): Check that key is a symbol.
1280 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
1282 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
1284 * async.c (async_pending): Removed declaration.
1286 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1288 * dynwind.c (scm_wind_chain): New debug function.
1290 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
1291 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
1292 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
1293 extra layer of functions around the body and handler of a thread.
1294 This extra layer makes sure that the handler is called in the
1295 dynamic context of the surround (= empty dynwind list), but under
1296 the *dynamic root* of the body. We can not use the dynamic root
1297 of the surround since that root belongs to another thread => stack
1298 is not handled correctly. It may seem ugly to use this extra
1299 layer, but the extra cost in terms of execution time is really
1300 negligible compared to the total amount of time required to create
1301 a thread, and it would reduce maintainability to duplicate the
1302 crucial and complicated steps performed by cwdr.
1304 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
1305 (SCM_ALLOW_INTS): Added thread switching code before interrupts
1306 get re-enabled. The important effect of this is that interrupts
1307 are blocked during thread switching so that thread data structures
1308 don't risk getting messed up by an unfortunate signal.
1309 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
1310 seems to do more aggressive optimization which actually move
1311 instructions around in these macros in a fatal way. Therefore:
1312 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
1313 just superstitious...)
1314 (SCM_TICK): Maybe do a context switch and take care of asyncs.
1315 This macro should be used instead of SCM_ASYNC_TICK since the
1316 latter doesn't do context switches any more.
1318 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
1319 instead of SCM_ASYNC_TICK.
1321 * coop.c, iselect.c: Since thread switches are now performed with
1322 interrupts masked, we can't use the old mechanism of delivering
1323 signals immediately when they arrive. Signals must instead be
1324 delivered when the asyncs run *after* the end of the critical
1325 section in scm_internal_select. But this also means after context
1326 switch so that the signal will be delivered to a different thread.
1327 To avoid this, I have changed the protocol of
1328 coop_wait_for_runnable_thread and friends so that they are allowed
1329 to return the original thread. So, if a signal arrives during
1330 scm_internal_select, we won't any longer be forced do a context
1331 switch, but can remain in the same thread and deliver the signal
1334 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
1335 scm_asyncs_pending and made it global.
1337 * iselect.c: Small fixes.
1339 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
1340 coop_condition_variable_init, coop_condition_variable_wait,
1341 coop_condition_variable_signal): Changed return type from `void'
1342 to `int'. This is to adhere closer to the pthreads interface.
1343 This, in turn, is part of an attempt to provide C versions of the
1344 mutex and condition variable primitives which can be part of a
1345 frontend to COOP or pthreads.
1347 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
1348 coop_condition_variable_destroy): New functions.
1350 * coop-threads.c (scm_wait_condition_variable): Use
1351 coop_condition_variable_wait_mutex.
1353 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
1354 Definitions moved to coop-defs.h.
1356 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
1357 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
1358 scm_cond_destroy): New C interface to mutecis and cond vars.
1360 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1362 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
1364 * iselect.c: Now several threads can wait on the same file
1365 descriptor. The behaviour is compatible with OS select: All
1366 threads waiting for the fd return with the same status.
1368 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1370 * coop-threads.c, threads.h (scm_spawn_thread): New function.
1371 Can spawn a thread from application C code.
1373 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1375 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
1376 gh_doubles2scm): New functions.
1378 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
1380 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
1381 commented-out version of gh_eval_str()
1383 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
1385 * socket.c (scm_bind): free soka after use.
1387 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
1389 * stime.c (tzvar): new variable.
1390 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
1391 avoid memory leaks when allocating.
1393 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
1395 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
1398 * gc.c, tags.h: Doc fixes.
1400 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1402 * eval.c (macro-eval!): Removed. This function was a design bug.
1403 It allowed memoized code to leak out to the scheme level. Most
1404 things that you could do with `macro-eval!' can be done with
1407 1997-12-20 Tim Pierce <twp@skepsis.com>
1409 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
1410 scm_fgets now depends on ftell(3) to know how many bytes were
1413 1997-12-15 Tim Pierce <twp@skepsis.com>
1415 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
1416 dealing with strings.
1418 1997-12-13 Tim Pierce <twp@skepsis.com>
1420 Make %read-line more suitable for implementing read-line efficiently.
1421 * ioext.c (scm_read_line): Strip the terminating newline from a
1422 string, and return a cons of the string and its terminator.
1424 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
1425 of the string that is read is stored in this memory location.
1426 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
1427 * genio.c, genio.h (scm_do_read_line): Update caller.
1428 * ports.h (scm_ptobfuns): Update typedef.
1429 * fports.c (scm_fptob, scm_pipob): Update struct.
1431 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1433 * filesys.c (set_element): Return file descriptor.
1434 (fill_select_type): Return the highest file descriptor.
1435 (scm_select): Tell select about the highest file descriptor. On
1436 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
1437 Therefore the extra overhead for calculating the maximum fd seems
1438 to be more than compensated. Is this correct? In any case,
1439 scm_internal_select will be much faster with this info.
1440 (scm_select, fill_select_type, set_element): Don't accept any kind
1441 of object in the file descriptor list or vector.
1443 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1445 * iselect.c (finalize_fd_sets): Bugfix.
1447 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1449 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1450 when using scm_internal_select (since we might switch to another
1453 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1455 * simpos.c (scm_system): always define: use sysmissing if not
1456 available. Check for HAVE_SYSTEM instead of _Windows (does
1457 Windows lack system or does it have an unusable one?).
1458 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1459 Let the argument be optional: if not supplied, call system(NULL).
1461 * ports.c (scm_close_port): relax the type check from OPPORTP to
1462 PORTP; closing a closed port is allowed.
1464 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1466 * fports.c (scm_fgets): Return if the last char in a chunk is
1467 newline. When fgets returns a string whose length is `size-1', it
1468 is ambiguous whether a whole line was retrieved, so we must check
1469 explicitly whether a line terminator is present.
1471 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1473 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
1474 before taking the CDR. (Thanks to Harald Meland.)
1476 * filesys.c (scm_stat): Slightly optimized.
1478 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
1480 * ports.c (scm_close_port): Make sure the port is open before
1483 * guile-snarf.in: Pass args through to gcc in a way that preserves
1484 whitespace boundaries. (Thanks to Greg Badros.)
1486 1997-12-02 Tim Pierce <twp@skepsis.com>
1488 * stacks.c (scm_frame_procedure): Reverse the logic in the return
1489 statement. (Thanks to Doug Evans for pointing this out.)
1491 1997-12-01 Tim Pierce <twp@skepsis.com>
1493 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
1495 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
1497 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
1498 errno macro expansion of this field name. (errno is a C
1499 preprocessor macro on some systems.)
1501 1997-11-29 Tim Pierce <twp@skepsis.com>
1503 * iselect.c: Doc fix.
1505 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
1507 * init.c (scm_start_stack): Removed initialization of
1508 scm_the_last_stack_var.
1510 * backtrace.h: Declare scm_the_last_stack_var.
1512 * backtrace.c: Define scm_the_last_stack_var.
1514 * root.c (mark_root): Don't mark the_last_stack_var.
1516 * root.h (scm_root_state): Removed the_last_stack_var.
1518 * throw.c: Added #include "fluids.h"
1519 (ss_handler): `the-last-stack' is now a fluid.
1521 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
1522 --> the_last_stack_fluid.
1524 * backtrace.c: Added #include "fluids.h"
1525 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
1526 (scm_backtrace): `the-last-stack' is now a fluid.
1528 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
1529 after scm_init_fluids.
1531 1997-11-28 Tim Pierce <twp@skepsis.com>
1533 * iselect.c: #ifdef USE_THREADS around thread-related includes.

1536 DLSYM_ADDS_USCORE to decide whether to add an underscore.
1538 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1540 * iselect.c (coop_next_runnable_thread,
1541 coop_wait_for_runnable_thread): Disable interrupts so that no
1542 async is executed before a potential error_revive.
1543 (scm_internal_select): Disable interrupts during the parts of the
1544 code which manipulate the sleep queue and the file descriptors.
1546 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1548 * Makefile.am: Added iselect.c and iselect.h.
1550 * coop.c (coop_qinit): Initialize fields used by
1551 scm_internal_select.
1552 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1553 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1554 replacement in iselect.c.
1555 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1556 coop_join): If GUILE_ISELECT enabled, use
1557 coop_wait_for_runnable_thread instead of
1558 coop_next_runnable_thread.
1559 (usleep, sleep): New replacements for system functions if
1560 GUILE_ISELECT is enabled.
1562 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1564 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1566 * filesys.c: Added #include "iselect.h". Moved FD-macros to
1567 iselect.h. Implement Scheme level `select' using
1568 scm_internal_select. (See NEWS.)
1570 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1572 * init.c: Call scm_init_iselect.
1574 * iselect.h, iselect.c: New files. Implements

1577 1997-11-27 Tim Pierce <twp@skepsis.com>
1579 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1580 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1581 and scm_must_free, since ultimately the string returned will be copied
1582 by scm_makfrom0str anyway. Also, read any characters that may have
1583 been pushed onto the port with scm_ungetc.
1584 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1585 * ioext.c (scm_read_line): Free string after Guilifying it.

1597 gh_repl (argc, argv).
1599 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1601 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1602 and to invoke scm_shell().
1603 (gh_launch_pad): took out the loading of boot-9.scm from here,
1604 since it is probably best to let the user control that. In fact,
1605 gh_repl() now invokes scm_shell() which does that.
1607 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1609 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()

1626 (gh_uniform_vector_ref): started implementing the uniform types in
1629 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
1631 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1632 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1634 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1636 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1637 configure.in was changed).
1639 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
1641 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1642 * Makefile.in: Regenerated.
1644 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1646 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1647 OPORT is an `open' port, not an output port.
1649 * filesys.c (scm_close, set_element, get_element, scm_chown,
1650 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use

1655 scm_set_port_filename_x, scm_port_mode,
1656 scm_close_all_ports_except, scm_set_current_output_port,
1657 scm_set_current_error_port): Likewise
1658 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1659 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
1661 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
1662 * backtrace.c (display_backtrace_body): Likewise
1663 * fports (scm_setvbuf): Likewise
1664 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,

1671 Minor problems with substring-related tag changes.
1672 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1673 exactly what we want to leave in to detect substrings.
1674 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1675 * tags.h: Fix diagrams and comments describing the S tag bit;
1676 remove vestigial remarks about the D tag bit.

1678 * strings.c: Formatting tweaks.
1680 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1681 variable first; then SCHEME_LOAD_PATH, with a warning message.
1682 (scm_parse_path): New function.
1683 * script.c: Doc fixes.
1685 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1687 Readline support, from Daniel Risacher.
1688 * readline.c, readline.h: New files.
1689 * init.c: #include "readline.h".
1690 (scm_boot_guile_1): Call scm_init_readline, if we have it.
1691 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1692 * Makefile.in: Regenerated.
1693 * scmconfig.h.in: Regenerated, after change to ../configure.
1695 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1697 * gh.h: gh_vector_set -> gh_vector_set_x
1699 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1701 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1702 with the ! -> _x mapping when going from Scheme to C.
1704 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1706 * gh.h (gh_reverse):
1714 (gh_assoc): added these gh_ functions implemented as macros.
1716 * gh_predicates.c (gh_null_p):
1717 (gh_string_equal_p): added these two missing predicates.
1719 * gh_list.c (gh_append):
1724 (gh_set_cdr_x): added these routines as I go through and try to
1725 complete the picture R4RS functions that should be mirrored in the
1728 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1730 * tags.h (scm_tc7_substring): Changed the comment and code to
1731 conform with the changes below. Folks! We have suddenly two new
1732 free tc7 codes!!! Jummy, jummy!
1734 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
1736 * Makefile.in: Rebuilt.

1762 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
1763 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
1765 Don't include "mbstrings.h".
1766 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
1767 (SCM_SYMBOL_SLOTS): Define as 4.

1770 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
1771 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
1772 struct.c, threads.c, throw.c, unif.c, variable.c: Use new

1792 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1794 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1796 * gh_test_c.c (c_vector_test): some improvements on the vector
1799 * gh.h (gh_vector): this used to exist but do the wrong thing.
1800 Now it (almost) does the right thing, though it takes a list
1801 instead of the individual arguments. I need to see how it could
1803 (gh_list_to_vector): added this function as a macro. Corresponds
1804 to Scheme's (list->vector ...).
1805 (gh_vector_to_list): added this function as a macro. Corresponds
1806 to Scheme's (vector->list ...).
1808 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1809 gh_vector_ref, so that it resembles the Scheme routines more.
1810 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1811 resembles the Scheme routines more.
1812 (gh_make_vector): this used to be (stupidly) called gh_vector().
1813 This is the right name, since it does the same thing as the Scheme
1814 (make-vector ...) procedure.
1816 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1818 * ports.h: #include "libguile/print.h"

1821 Some indentation fixes.
1823 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
1824 longer a user field; New field: class_flags.

1831 gh_int2scmb(), which is now tagged as obsolete.
1833 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1835 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1836 macros should by convention not test for NIMPness.)
1837 (SCM_COERCE_OPORT): Adjust indentation.
1839 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1840 SCM_NIMP test before SCM_PRINT_STATE_P.
1842 * struct.c, struct.h, gc.c: Renamed:
1843 scm_struct_i_layout --> scm_vtable_index_layout

1847 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1849 * struct.c (scm_print_struct): Use new printer slot; Default
1850 printing: Also output hex code of vtable so that type identity
1851 will be indicated as well.
1852 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1853 Removed struct_printer_var; Removed struct-vtable-offset;
1854 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1855 vtable-offset-user): New constants.
1857 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.

1860 the type represented by this vtable.
1862 * print.c (scm_iprin1): Don't print arguments of macro
1863 transformers. (They are always: exp env.); Bugfix: Unmemoize
1864 transformer source with correct environment.
1866 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1868 Streamlining of call-with-dynamic-root:

1872 (cwdr_outer_body): Removed.
1873 (cwdr_handler): New function.
1874 (scm_internal_cwdr): New function to perform the function of cwdr
1875 but take args that are more useful to C code. Also, the handler
1876 is now invoked *outside* of the new dynamic root, like the docs
1877 say. We no longer have to catch absolutely all errors, the caller
1878 is responsible for using a handler that does not throw, if he
1880 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1881 * root.h (scm_internal_cwdr): New prototype.
1883 Even more but risky streamlining:
1885 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1886 allocation of the jumpbuf of a root continuation. The changes
1887 below are controlled by it. They are now deactivated.
1888 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1889 the JMPBUF of the scm_rootcont to NULL before returning.
1891 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1892 when they are non-NULL.
1893 (scm_gc_mark): Likewise, mark only when non-NULL.
1895 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1896 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1898 * gc.c (scm_done_malloc): New function.
1899 gc.h (scm_done_malloc): New prototype.
1901 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.

1908 a certain value is acceptable as a port argument.
1909 (scm_print_state_vtable): New variable.
1910 (scm_free_print_state): Set `revealed' field to false.
1911 (scm_iprin1): Call user supplied closure printer with
1912 scm_printer_apply. Print in the traditional way when there isn't
1913 one or when it returns #f.
1914 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1915 Accept a port/print-state pair in addition to just a port.
1916 (scm_prin1): Don't return the print_state to the pool when it has
1918 (scm_printer_apply): Set `revealed' field of print_state to true.
1919 (scm_init_print): Set scm_print_state_vtable.
1920 (print_state_fluid, print_state_fluid_num): Removed.
1922 * throw.h (scm_handle_by_proc_catching_all): New prototype
1923 throw.c (scm_handle_by_proc_catching_all): New function
1925 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1927 * Makefile.in: Regenerated with automake 1.2c.
1929 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1931 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1932 was looping endlessly.
1934 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1936 * strports.c (scm_eval_string): Don't close the port.
1938 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1939 former returns a nice normal integer. (Thanks to Daniel
1942 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1944 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1945 makefile variable as a build parameter called LIBS. The
1946 build-guile program will use this, for the time being.
1947 * Makefile.in: Regenerated.
1949 Thanks to Shiro Kawai:
1950 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1951 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1954 * Makefile.in: Regenerated with automake 1.2a.
1956 * script.c (scm_compile_shell_switches): If we hit the -c or --
1957 arguments, don't set the car of (command-line) to scm_usage_name,
1958 the prettified name of the guile executable; give it the full
1959 path, the way shells usually handle $0.
1961 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1963 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1964 Scheme-level name `array-map' and renamed `serial-array-map' to
1965 `serial-array-map!'.
1967 * backtrace.c: Introduced exception handlers which now enclose
1968 `display-error' and `display-backtrace' so that error reporting
1969 won't get into infinite loops if an error occurs during displaying
1970 of the error. This can very easily happen with user supplied
1971 print call-back routines.
1973 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1975 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1976 the names `serial-array-map' and `array-map' should be removed.)
1978 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1980 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1981 Added #include "objects.h"
1983 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1984 Add #include "feature.h".
1986 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1987 (modinclude_HEADERS): Added objects.h.
1989 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1990 This test is needed at many places in the code and should be
1991 abstracted. (Motivated by the need of this test in libguiletk.)
1993 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1994 (scm_eval_string), load.c (scm_primitive_load,
1995 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1996 Use SCM_EOF_OBJECT_P.
1998 * eval.c (scm_init_eval): Add feature `delay'.
2000 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2002 * scmhob.h: Removed.
2004 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2006 * list.h (SCM_LISTn): New macros. Make list creation in C code
2007 prettier. The idea comes from STk.
2009 * sequences.h, sequences.c, append.h, append.c: Removed. These
2010 files implemented non-R4RS operations which would encourage
2011 non-portable programming style and less easy-to-read code.
2013 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
2016 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
2017 sequences.h, #include append.h.
2019 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
2022 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
2024 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
2026 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
2028 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2030 * eval.c: Added #include "objects.h"
2032 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
2035 * smob.c (scm_smob_prehistory): Create two objectsmobs with
2036 adjacent smob numbers.
2038 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2040 * procprop.h: Added declaration of scm_i_inner_name.
2042 * gsubr.c: New global symbol scm_i_inner_name.
2044 * debug.c (scm_procedure_name): Try procedure property
2045 `inner-name' if `name' fails.
2047 * print.c (scm_iprin1): Use scm_macro_name.
2049 * eval.c (scm_m_define): Give names to macros as well; Only the
2050 first top-level definition gives a procedure/macro a name.
2051 Otherwise confusing names can turn up in backtraces.
2052 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
2053 `name'; Give names to macros as well.
2055 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
2056 (scm_macro_transformer): Use SCM_CLOSUREP instead of
2059 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2061 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
2063 (prinmacro): Removed. The code has been moved/merged into print.c
2064 in order to decrease code redundancy. We want macros to print in
2065 a way equivalent to procedures, and it would be silly to duplicate
2066 the required code. (We don't want to maintain two places.)
2067 (macrosmob): Print field is now a NULL pointer.
2069 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
2070 scm_macro_transformer): New prototypes.
2071 (scm_tc16_macro): Declared.
2073 * print.c (scm_iprin1): Added code for printing of macros. Macros
2074 are now printed in a way equivalent to procedures.
2076 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
2078 * procs.h (scm_closure_p): Added declaration.
2080 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2082 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
2083 Shouldn't pass "heap" as the subr name.
2085 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
2087 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
2088 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
2089 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
2090 gh_equal_p): Use SCM_NFALSEP, instead of testing against
2091 SCM_BOOL_T. Any non-false value is true.
2093 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2095 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
2096 scm_gensym): Added prototypes.
2098 * symbols.c (scm_gensym): New function. This will speed up
2099 certain types of applications (such as macro systems) which
2100 generate lots of symbols.
2102 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2104 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
2106 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
2108 * unif.c (scm_shap2ra): tighten the checking of the array dimension
2109 specifier, since (2) or (2 . 3) would cause SEGV.
2110 (scm_transpose_array): more argument checking fixes.
2112 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
2114 * Makefile.in: Regenerated.
2116 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
2118 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
2120 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2122 * error.c, error.h (scm_error_callback): Removed (see NEWS).
2124 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
2126 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
2127 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
2130 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
2131 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
2132 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
2133 scm_array_p, scm_array_rank, scm_array_dimensions,
2134 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
2135 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
2136 scm_array_prototype): Added case scm_tc7_wvect.
2138 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
2140 * errno.h: prototype for scm_strerror.
2141 * error.c (scm_strerror): new procedure.
2143 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2145 * list.c (scm_list_append_x): Allow non-pair as last argument.
2146 This is consistent with the R4RS append and is probably the
2147 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
2149 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2151 * stime.h: prototype for scm_times.
2152 * stime.c (scm_times): new procedure.
2153 * ioext.c (scm_fseek): if the first argument is a file descriptor
2155 (scm_ftell): if the first argument is a file descriptor call lseek
2157 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
2158 * filesys.c (scm_chmod): if the first argument is a file descriptor,
2160 (scm_chown): if the first argument is a port or file descriptor,
2162 (scm_truncate_file): new procedure.
2163 Add DEFER/ALLOW INTS to a few other procedures.
2164 (scm_fsync): new procedure.
2165 (scm_open_fdes): new procedure.
2166 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
2168 (scm_fcntl): the first argument can now be a file descriptor. The
2169 third argument is now optional.
2171 * posix.c (scm_execl, scm_execlp): make the filename argument
2172 compulsory, since omitting it causes SEGV.
2173 (scm_sync): return unspecified instead of #f.
2174 (scm_execle): new procedure.
2175 (environ_list_to_c): new procedure.
2176 (scm_environ): use environ_list_to_c. disable interrupts.
2177 (scm_convert_exec_args): take pos and subr arguments and
2178 improve error checking.
2180 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2182 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
2183 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
2184 argument to SCM_ASSERT. Furthermore, the name of the function
2185 should be passed as first argument when signalling
2186 SCM_WNA. (Thanks to Thomas Morgan)
2188 * gsubr.c (scm_gsubr_apply): From Radey Shouman
2189 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
2190 dispatches on the number of actual args has a default case
2191 reporting an internal error. This is a vestige from a version
2192 that mallocated a SCM vector to hold the arguments. In the
2193 current version this check is too late: if it ever happens we will
2194 have already overstepped the bounds of the array.
2196 Also, the patch [...] adds a check for too many actual arguments."
2198 mdj: Removed check for "internal programming error".
2200 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2202 * gh_io.c (gh_write): New function.
2204 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
2205 throw.c (scm_internal_stack_catch): New sibling to the other catch
2206 functions. Code moved from gh_eval.c.
2207 throw.h: Added header.
2208 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
2209 scm_internal_stack_catch.
2211 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2213 * ioext.h: fix up prototypes.
2214 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
2215 Scheme name is now dup->fdes.
2216 (scm_dup_to_fdes): make the second argument optional and
2217 fold in the functionality of scm_primitive_dup.
2218 (scm_primitive_dup): deleted.
2220 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
2222 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
2223 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
2224 ultrix are defined. Use setvbuf instead of setbuf.
2225 (scm_setvbuf): new procedure.
2226 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
2227 (scm_setfileno): moved from ioext.c.
2228 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
2229 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.

2233 * fluids.c (scm_fluid_p): New function.
2234 * fluids.h (scm_fluid_p): New prototype.

2239 state as nested data while they are printed.
2240 (print_state_fluid, print_state_fluid_num): New variables.
2241 (scm_init_print): Initialize them.
2242 (scm_iprin): If print_state_fluid carries a print_state, use that
2243 instead of creating a new one.
2244 (scm_printer_apply, apply_stub, struct apply_data): New
2245 definitions to help with calling printer functions written in
2247 * print.h (scm_printer_apply): New prototype.
2249 * struct.c (scm_print_struct): Use scm_printer_apply to call the
2250 user defined struct printer.

2260 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
2261 SCM_ASSERT: arg comes before pos.
2263 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2265 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
2266 to a list of length zero correctly.
2268 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2270 Supply an `fgets' method for port objects to do fast line i/o.

2284 * ioext.h: removed scm_duplicate_port prototype.
2286 * ioext.c (scm_primitive_dup2): return the new file descriptor
2287 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
2289 (scm_fdopen): bug fix: don't try to make port unbuffered until its
2290 stream has been set.
2291 (scm_duplicate_port): deleted, there's now an implementation in
2293 (scm_primitive_dup2): do nothing if newfd == oldfd.
2295 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
2297 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the

2301 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
2303 * fluids.c (next_fluid_num): don't do
2304 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
2306 * ports.h: prototypes too.
2307 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
2309 * fports.h: prototype too.
2310 * fports.c (scm_evict_ports): moved from ioext.c.
2312 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>

2319 and ports (scsh compatible).
2321 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
2324 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
2326 * fluids.c, fluid.h: New files.
2327 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
2328 (modinclude_HEADERS): Added "fluids.h"

2337 (scm_make_root): Call scm_copy_fluids to make fluid bindings
2338 unique for the new root when it has a parent.
2340 * smob.h: Include "libguile/print.h" to make scm_print_state
2343 * dynl.c (free_dynl_obj): New function to free the dynamic object
2344 data. (dynl_smob): Use it.
2345 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
2346 the dynamic object data below the linking of the object to avoid
2347 memory leak when the linking code throws an error. Now the code
2348 leaks a whole dynamically linked library when must_malloc throws,
2349 but that should be much less likely.
2351 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
2353 Changes to compile under gnu-win32, from Marcus Daniels:
2354 * stime.c (tzset): If tzset isn't provided, make it a NOP.
2355 (scm_localtime): Change SCM_EOF to SCM_EOL.
2356 (scm_mktime): Likewise.
2357 * socket.c: Don't include sys/un.h unless autoconf tells
2358 us Unix domain sockets are available.
2359 (scm_fill_sockaddr): Ignore Unix domain code.
2360 (scm_addr_vector): Likewise.
2361 (scm_init_addr_buffer): Likewise.

2368 was found during autoconf (in this case, getgroups).
2369 (scm_setpwent): For setpwent.
2370 (scm_setegid): For setegid.
2371 * net_db.c (scm_inet_netof): Don't include unless support

2386 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
2387 scm_misc_error, not SCM_EOF.
2389 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
2390 arguments for formatting the error message, not SCM_BOOL_F. I
2391 think this is left over from the (eq? '() #f) days.
2393 * read.c (recsexpr): Give this a dummy definition if
2394 DEBUG_EXTENSIONS isn't #defined.
2396 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
2398 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

2408 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
2409 alloca.lo will be included in @LIBLOBJS@. Something better than
2410 this should be possible.
2411 * Makefile.in: Regenerated.
2413 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2415 * simpos.h: prototype for scm_primitive_exit.
2416 * simpos.c (scm_primitive_exit): new procedure, terminates the
2417 process without unwinding the stack.
2419 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
2421 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
2422 argument and logior its components together, so the user doesn't
2423 have to do this explicitly. Also, if regexp/basic is supplied, then
2424 turn off REG_EXTENDED.
2425 (scm_init_regex_posix): New regexp/basic symbol.
2426 (REG_BASIC): #define this if it is not already present.
2428 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2430 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
2431 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
2432 (CLEANFILES): New target, clean versiondat.h, libpath.h.

2439 years in usage message.
2441 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
2442 * Makefile.in: Regenerated.
2444 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
2445 flag; I don't think we support it.
2446 (scm_make_regexp): Make sure the user doesn't pass the
2449 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
2451 (scm_init_regex_posix): Define constants for the REG_mumble flags;
2452 name them according to the SCSH convention: regexp/mumble.
2454 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
2456 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>

2459 Makefile directory variables. Print a message, but don't print
2461 (versiondat.h): Print a message, but don't print all the commands.
2462 * load.c: #include "alist.h".
2463 (init_build_info): New function.
2464 (scm_init_load): Call it.
2465 * Makefile.in: Regenerated.
2467 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
2469 * root.c: Establish a reliable catch-all handler for the new root.
2470 After all the Scheme handler function might signal an error too,
2471 and we don't want to lose that.
2472 (cwdr_inner_body): Renamed from cwdr_body.
2473 (cwdr_outer_body): New function, to establish the user's handler,
2474 and pass control to cwdr_inner_body.
2475 (cwdr): Establish the reliable catch-all handler here, and pass
2476 control to cwdr_outer_body.
2477 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
2478 the user's handler through to cwdr_outer_body.
2479 * throw.c (scm_handle_by_message): Move guts into....
2480 (handler_message): New static function.
2481 (scm_handle_by_message_noexit): New function.
2482 * throw.h (scm_handle_by_message_noexit): New prototype.
2484 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
2485 across this. Only works on GCC. Otherwise, we hope for the best.
2486 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2487 the feeling that real thread systems will not need this...
2489 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2491 Try to detect when people are using one version of libguile and a
2492 different version of ice-9. People have been skewing things and
2493 sending in bug reports.
2494 * Makefile.am (versiondat.h): New file to generate.
2495 * version.c: #include "versiondat.h", to get version info.
2496 (scm_libguile_config_stamp): New function.
2497 * script.c: #include "version.h".
2498 (scm_compile_switches): Call scm_version to get version number.
2499 * scmconfig.h.in, Makefile.in: Regenerated.
2500 * Makefile.in: Regenerated.
2502 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
2503 primitive definitions under their Scheme names.
2505 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2506 1:2. Helps avoid confusion between installed and uninstalled libs.
2508 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2511 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2512 backslash from definition; this should be used like: GDB_INTERFACE;
2514 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2516 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
2517 new port unbuffered until its stream has been set.
2519 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2521 * ports.h: new prototype.
2522 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
2524 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
2526 Make things compile neatly under Sun's C compiler.
2527 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
2528 * extchrs.c (xmbtowc): Make the second arg a normal char, not
2529 unsigned, because that's what the ANSI function takes.
2530 * extchrs.h (xmbtowc): Corresponding change to prototype.
2531 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2533 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2534 argument plain char *.
2535 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2537 * tag.c (scm_tag): Remove unreachable statement.
2538 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2539 top of the word, it should be unsigned.
2541 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2542 is defined, to avoid warnings; it's only used in the
2543 conflict-checking code. Which might go away anyway.
2544 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2545 conditionals; put the label definition in an #if too, to stifle
2548 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2549 ChangeLog-threads in the distribution.
2550 * Makefile.in: Regenerated.
2552 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2554 * guile-snarf.in: Changed regexp to support CPPs that insert
2555 whitespace between lexical tokens (which munges the `%%%' snarf
2558 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2560 * load.c (scm_init_load_path): Append $(datadir)/guile to
2561 %load-path, so modules do not have to be installed in Guile's
2562 current version directory.
2564 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2566 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2567 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2568 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2569 call the sysdep functions with deferred ints.
2570 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2571 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2572 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2575 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2578 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2580 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2582 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2584 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2587 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2589 * eval.c (scm_lookupcar1): New procedure to cope with a race
2590 condition during lookup (when using threads).
2591 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2592 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2595 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2597 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2598 supplied. (Change from Tim Pierce.)
2600 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2602 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2603 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2604 default and not `()'. `#f' is the canonical non-value in Scheme,
2607 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2609 * struct.c (struct_printer): New variable that holds a handle on
2610 the Scheme variable *struct-printer*. This variable can be set by
2611 Scheme code to override the printing of structures.
2612 (scm_print_struct): If struct_printer is set, call it. If it is
2613 not set, or returns #f, print the structure in the old fashion.
2614 Include "eval.h" for scm_apply.
2616 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2618 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2619 scm_struct_i_n_words to get the number of fields, not
2620 -scm_struct_n_extra_words.
2622 On the route to fancier struct printing:
2623 * struct.c (scm_print_struct): New function to print a structure.
2624 Include "genio.h" to support it. This function doesn't do
2625 anything interesting right now, but I think it should be here
2627 * struct.h: Include "print.h" and add prototype for
2629 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2630 print structures ourself.
2632 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2634 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2635 before applying the handler in case it doesn't return.
2637 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2639 * scmsigs.h, async.h: updated.
2641 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2644 * posix.c (scm_uname): interpret only negative values as an error.
2645 Solaris normally returns a positive value.
2647 * script.c (scm_compile_shell_switches): if we are not going into
2648 an interactive repl, set scm_mask_ints to zero so that asyncs can
2651 * simpos.c (scm_system): don't ignore/unignore signals around
2654 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2657 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2658 done in boot-9.scm instead.
2660 * scmsigs.c, async.c: Major rewriting of signal handling code.
2661 (scm_sigaction): new procedure.
2662 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2664 (scm_raise): return unspecified, throw error on failure.
2666 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2668 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2669 feature, to help boot-9.scm decide whether to import the regex
2672 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2674 * eval.c: Include scmconfig.h at the beginning of the file so that
2675 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2678 * regex-posix.c: #include "_scm.h" before conditionally #including
2679 <regex.h>; the former defines HAVE_REGCOMP.
2681 * regex-posix.c: #include <regex.h> conditionally, so the file is
2682 CPP'able (for dependency scanning) even on systems that don't have
2685 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2687 Add new R4RS-compliant syntax for keywords.
2688 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2689 regardless of the setting of the `keywords' read option.
2690 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2691 can be re-read no matter what the setting of the `keywords' read
2694 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2696 Add support for POSIX regular expressions.
2698 * regex-posix.c, regex-posix.h: New files. (Some code
2699 is taken liberally from rx/rgx.c in the old Guile dist.)
2701 * init.c: Include regex-posix.h.
2702 (scm_boot_guile_1): Call scm_init_regex_posix.
2704 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2705 Add regex-posix.[ch] sources.
2706 * Makefile.in: Regenerated.
2708 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2709 to do this automatically? It didn't for me, bleh.)
2711 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2713 * fports.c (print_pipe_port): New function.
2714 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2715 latter doesn't even take the right arguments.
2717 * Makefile.am: Increment shared lib revision number. I think
2718 sometimes the uninstalled Guile finds the installed shared lib;
2719 Gord says doing this might help. As things turned out, I can't
2720 say whether it does.
2721 * Makefile.in: Regenerated.
2723 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2724 passing it as the closure argument to scm_boot_guile. (Bill
2727 * ports.c (print_void_port, putc_void_port, puts_void_port,
2728 write_void_port, flush_void_port, getc_void_port, close_void_port,
2729 noop0): Use ANSI prototypes instead of K&R declarations, so the
2730 initialization of void_port_ptob gets aggressively type-checked.
2731 Fix arguments of print_void_port and write_void_port. (Bill

2765 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2767 * script.c (scm_find_executable): Use prototype-style definition
2768 here; apparently it's not quite right to have const in a prototype
2769 and then use a K&R declaration. I wonder if stuff like this will
2770 go away if we compile with -Wrequire-prototypes, or whatever that
2771 is... (Bernard URBAN)
2773 * scmhob.h: New text from Bernard URBAN.
2775 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2777 * script.c: Don't #define const on hpux. Configure takes care of
2778 this. (Thanks to Larry Schwimmer.)
2780 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2781 decide whether to #include <unistd.h>, instead of listing a bunch
2782 of systems. Don't #include stdio twice. Removed dyked-out
2783 definition of scm_find_impl_file.
2785 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2787 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2788 library version info to 1:0.
2789 * Makefile.in: Regenerated.
2791 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

2795 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2796 throw.c: Update copyright years; these files have been worked on
2797 significantly in 1997, but only had copyright years for 1996.
2798 Also, change name of copyright holder on some from Mikael
2799 Djurfeldt to Free Software Foundation; he has signed papers
2800 assigning the changes to the FSF.
2802 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2803 reason not to give the user the option.
2805 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2806 Return #f on end-of-file when scanning table (i.e. when called
2807 with no arguments). Try to catch errors, when we can.
2808 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2810 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2811 external declarations. These are useful.
2813 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2815 * posix.c: don't include <sys/select.h> or define macros for
2816 select, since they were not used in this file.
2818 * filesys.c (scm_select): make the fifth parameter microseconds,
2819 not milliseconds. let the fourth parameter be either a real value
2820 or an integer or #f. The first, second and third arguments can
2821 now be vectors: the type of the corresponding return set will be
2823 (set_element, get_element): new static procedures.
2825 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2827 * strports.c (scm_eval_string): New function.
2828 (scm_eval_0str): Trivially re-implemented in terms of
2830 * strports.h (scm_eval_string): New extern decl.
2832 * net_db.c (h_errno): Add extern decl for this.
2834 * fports.c (local_pclose): New function.
2835 (scm_pipob): Use it in the initializer here.
2838 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2839 Use a meaningful error message when signalling an error. For
2840 this, scm_gethost must check h_errno rather than errno.
2842 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2844 * Makefile.in: Regenerated, using automake-1.1p.
2846 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2848 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2849 not SCM_UNSPECIFIED.
2851 * script.c (scm_compile_shell_switches): don't append (quit) if
2853 (scm_shell): call scm_exit_status and exit on the result of the
2856 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2858 Ensure that shared substrings are handled properly when passed to
2859 a system call or other foreign function. Many thanks to Tim
2861 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2862 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2863 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2864 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

2876 SCM_COERCE_SUBSTR to make sure shared substrings are
2879 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2881 * error.c (scm_error): Add newline to error message.
2883 * init.c (scm_init_standard_ports): Doc fix.
2885 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2887 * dynl-shl.c: Completely replaced with new code from Bernard
2890 * script.c (scm_ice_9_already_loaded): New variable.
2891 (scm_compile_shell_switches): Use it.
2893 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2895 * filesys.c (scm_input_waiting_p): add missing third argument to

2899 calling gmtime in case they share a buffer.
2900 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2903 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2905 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2907 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2909 * Makefile.am (check-local): New target, which causes 'make check'
2910 to run gh_test_c and gh_test_repl, with some trivial input.
2911 * Makefile.in: Rgnrtd.
2913 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2915 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2918 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2920 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2921 sure how this was supposed to work.
2922 (scm_async_click): don't send SCM_TICK_SIGNAL.
2923 (scm_init_async): don't initialize %tick-thunk.
2925 * the following change doesn't affect the Scheme interface:
2926 gc-thunk is called at the end of garbage collection. however it's
2927 no longer implemented by pretending it's a signal.
2929 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2930 system async corresponding to scm_gc_thunk.
2931 * async.h: declare scm_gc_async.
2932 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2933 gc-thunk directly, instead of going through a signal handler.
2934 (scm_gc_async): new variable, points to the GC system-async.
2935 (scm_init_async): save the GC async as scm_gc_async instead
2936 of using system_signal_asyncs.
2937 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2939 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2941 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2942 Don't screw up if we're interrupted.
2943 * Makefile.in: Regeneradet.
2945 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2947 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2949 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2950 we're not using AM_INIT_GUILE_MODULE any more.
2951 * Makefile.in: Reneregated.
2953 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2955 Functions for finding variable bindings, grace à Tim Pierce.
2956 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2957 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2959 Get 'make dist' to work again.
2960 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2961 * Makefile.in: Regenerated, like a surry without a fringe on top.
2963 Changes for reduced Guile distribution: one configure script,
2965 * configure.in, configure: Removed.
2966 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2967 real configure script lives.
2968 * Makefile.in, scmconfig.h.in: Regenerated.
2970 * init.c: #include "script.h", to get prototype for script.c's
2973 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2975 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2976 scm_must_malloc, not raw malloc.
2978 * script.c (scm_compile_shell_switches): Dyke out debugging output
2981 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2983 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2985 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2986 system has them. Hope this is safe. Previously
2987 sys/timeb.h was included if HAVE_FTIME was defined or if
2988 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2989 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2991 * ioext.c (scm_setfileno): add missing third argument to
2992 scm_misc_error call.
2994 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2996 * eq.c (scm_equal_p): Correctly compare strings of different
2997 varieties. (Thanks to Tim Pierce.)
2999 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
3001 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
3002 #! block comment must occur on a line all by itself.
3004 Move most of the guts of shell command processing into libguile,
3005 so guile.c can be very small (and eventuallly auto-generated. (I
3006 mean, generated mechanically, not self-generated. Hmm.))
3007 * guile.c, script.c, script.h: New source files.
3008 * init.c (scm_boot_guile_1): Call scm_init_script.
3009 * libguile.h: #include "script.h".
3010 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
3011 targets, for new executable.
3012 (libguile_la_SOURCES): Mention script.c.
3013 (modinclude_HEADERS): Add script.h.
3014 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
3015 not dynamic linking is enabled. This is because we're generating
3016 executables now. Move CY_AC_WITH_THREADS call after those, so the
3017 values of cy_cv_threads_libs captures the libs chosen above.
3018 * Makefile.in, configure, aclocal.m4: Regenerated.
3020 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
3021 We don't maintain this interface any more, and it just confuses
3024 * alloca.c: #include <scmconfig.h>, not <config.h>.
3025 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
3026 it'll get included in disties.
3028 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
3030 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
3031 be distributed, because they confuse people.
3032 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
3034 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
3036 * configure.in: check for presence of gethostent (not present on
3037 OpenBSD by default).
3038 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
3039 * configure, scmconfig.h.in: Regenerated.
3041 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
3043 * backtrace.c (scm_backtrace): Split message string across
3044 newlines properly. GCC is more tolerant of this than other
3047 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
3049 Merge threads directory into libguile.
3050 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
3051 threads.h: New source files.
3052 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
3053 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
3055 (modinclude_HEADERS): Add threads.h, coop-defs.h.
3056 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
3057 coop-threads.c.cygnus, coop-threads.h.cygnus.
3058 * configure.in: If we're using threads, include threads.o in
3060 * _scm.h, libguile.h: threads.h lives in this directory now.
3061 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
3062 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
3063 currently used, but brought along for information's sake.
3064 * ChangeLog-threads: log from old 'threads' directory.
3065 * Makefile.in, configure: Rebuilt.
3067 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
3069 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
3072 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
3074 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
3076 Merge GH interface library into libguile.
3077 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
3078 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
3079 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
3080 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
3082 (EXTRA_libguile_la_SOURCES): ... here.
3083 (pkginclude_HEADERS): Add variable, to get gh.h installed.
3084 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
3085 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
3086 New variables, describing how to build the gh test programs.
3087 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
3088 build the test programs, and we probably should have been linking
3089 libguile.la against them all along, to support AIX shared libs.
3090 Add cflags for threads to CFLAGS; add libs for threads to new
3091 variable THREAD_LIBS, used in Makefile.am.
3092 * ChangeLog-gh: log from old `gh' subdirectory.
3093 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
3095 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
3097 * acconfig.h: Undo change of Apr 9; including the definition of
3098 PACKAGE in the guile headers conflicts with applications' own
3100 * scmconfig.h.in: Regenerated.
3102 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

3109 when PROC is receiving no arguments.
3111 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
3113 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
3114 have S_IFSOCK. This is the case under Ultrix.
3116 * posix.c (scm_status_exit_val, scm_status_exit_val,
3117 scm_status_term_sig, scm_status_stop_sig): Modified to work with
3118 Ultrix versions of WIFSTOPPED, etc., which assume that their
3119 arguments are lvalues (hmm).
3121 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
3123 * eval.c: Doc fixes.
3125 * throw.c: Doc fixes; rearranged.
3127 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
3129 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
3131 * acconfig.h: Added entry for PACKAGE.
3132 * scmconfig.h.in: Regenerated.
3134 Changes to work with automake-1.1n, which has better libtool support.
3135 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
3136 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
3138 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
3140 * Makefile.in: Rebuild.
3142 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3144 * stime.c (scm_mktime): take an optional zone argument.
3145 (scm_localtime): check putenv return value.
3146 (scm_strftime, scm_strptime): moved from posix.c. move #include
3148 stime.h, posix.h: update prototypes.
3149 (bdtime2c, setzone, restorezone): new static procedures.
3150 (scm_mktime, scm_strftime): use them.
3151 (scm_strftime): don't call mktime before strftime. Use
3152 filltime for return value.
3153 (filltime): convert NULL zname to #f.
3154 (scm_strptime): return a count of characters consumed, not
3155 the remaining string.
3157 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3159 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
3160 (scm_mktime): likewise.
3162 Uncomment localtime and mktime.
3164 * configure.in: add AC_STRUCT_TIMEZONE.
3166 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3168 * stime.c (scm_init_stime): don't define ticks/sec.
3169 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
3170 return value problem and is still portable.)
3172 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3174 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
3175 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
3176 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
3177 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
3178 cpp_err_symbols.c): Corresponding changes.
3179 * Makefile.in: Regenerated.
3181 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3183 * posix.c (scm_putenv): don't check HAVE_PUTENV.
3184 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
3185 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
3186 * putenv.c: new file, from sh-utils 1.12.
3188 * posix.c (scm_environ): use malloc in place of scm_must_malloc
3189 since allocation isn't for Scheme objects.
3190 (scm_putenv): copy strings before placing in the environment.
3192 * stime.c (scm_current_time): throw an error if time returns -1,
3193 instead of returning #f.
3194 (scm_get_internal_real_time, scm_get_internal_real_time): use
3195 scm_long2num for return value instead of SCM_MAKINUM.
3197 * stime.h: prototypes updated.
3199 * stime.c (scm_time_in_msec): apparently unused, deleted.
3201 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
3203 * configure.in: check for gettimeofday.
3205 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
3206 which may be more usefully portable than a gettimeofday interface.
3208 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
3210 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
3212 * Makefile.in: Regenerated.
3214 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3216 * stime.c (filltime): recovered static procedure.
3217 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
3220 * posix.h: add prototype for scm_close_pipe, remove prototypes for
3221 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
3223 * posix.c (scm_mknod): split the mode argument into type and perms
3224 arguments, like the extra fields returned by stat.
3226 * fports.c (scm_pipob): set the close, free and print procedures.
3227 (scm_close_pipe): new procedure.
3229 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
3230 define them in boot-9.scm
3232 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3234 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
3235 wan't defined. Don't include fd.h.
3237 * Previously fd.h was regenerated whenever configure was run,
3238 forcing a couple of files to be recompiled.
3240 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
3241 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
3242 Check for _fileno as well as _file.
3244 * ioext.c: don't fd.h.
3245 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
3248 * Change the stratigy for getting information about errno
3249 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
3250 generating lists of symbols during the build process, which will
3251 not always work, include comprehensive lists in the distribution.
3252 To help keep the lists up to date, the "check_signals" and
3253 "check_errnos" make targets can be used.
3255 * configure.in: don't check for a command to extract errno codes.
3256 * Makefile.am: update file lists, remove errnos.list and errnos.c
3257 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
3258 check_errnos targets.
3259 (CLEANFILES): remove errnos.c and errnos.list, add
3260 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
3261 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
3262 * errnos.default: deleted.
3263 * cpp_signal.c: new file.
3264 * cpp_errno.c: renamed from errnos_get.c.
3265 * cpp_err_symbols, cpp_sig_symbols: new files.
3266 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
3267 * error.c (scm_init_error): #include cpp_err_symbols instead of
3269 * posix.c (scm_init_posix): don't intern signal symbols. #include
3272 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
3274 * strop.c (scm_i_index): allow the lower bound to be equal to the
3275 length of the string, so a null string doesn't always give an error.
3277 * posix.h: new prototypes.
3278 * posix.c (scm_status_exit_val, scm_status_term_sig,
3279 scm_status_stop_sig): new functions, as in scsh. They break down
3280 process status values as returned by waitpid.
3282 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
3284 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
3285 configure doesn't know about it.
3287 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3289 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
3291 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
3292 which defines C variables with global linkage.
3294 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3296 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
3299 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
3301 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
3302 has time to check why this doesn't work well with continuations.
3304 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
3306 * Fix shell syntax error; some shells won't tolerate
3307 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
3309 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3311 * posix.c (scm_uname): throw an error if uname fails instead
3314 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
3316 * error.c (err_head, scm_errno, scm_perror): obsolete procedures

3323 * acconfig.h: Removed PACKAGE.
3325 * scmconfig.h.in: Regenerated.
3327 * snarf.h: g++ says it's non-portable not to specify the first
3328 argument in a varargs declaration. I introduced the first
3329 argument by using preprocessor conditionals.
3331 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
3333 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
3334 (scm_freopen): use RO string macros for filename and modes.
3335 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
3337 * posix.c (scm_getgrgid): simplify conversion of name to C string.
3338 (scm_mknod): use RO string macros for path.
3340 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
3341 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
3343 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
3344 use SCM_ROSTRINGP and SCM_ROCHARS.
3346 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3348 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
3351 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
3352 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
3353 support for byte vectors.
3355 * print.c (scm_iprin1): Limit number of vector elements printed
3356 according to pstate->length.
3358 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3360 * backtrace.c (scm_display_error_message): don't segv if message
3363 * error.h: prototype for scm_error_scm.
3365 * error.c (scm_error_scm): new procedure, reimplements scm-error
3366 in C and uses scm_error.
3368 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3370 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
3371 pointer to the Scheme variable read-hash-procedures and intern it
3372 in scm_init_read. Modify scm_read_hash_extend and
3373 scm_get_hash_procedure to use the pointer.
3375 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3377 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
3378 (SCM_KEYWORD_STYLE): defined.
3380 * read.c (scm_read_opts): add a keywords option. This isn't a
3381 boolean option, in case someone wants to add support for DSSSL
3383 Setup scm_keyword_prefix symbol.
3384 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
3386 I've left keyword support disabled by default, since it doesn't
3387 seem to break the module system and it gives R4RS standard behaviour.
3388 It can be reactivated with (read-set! keywords 'prefix).
3390 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3392 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
3393 before constructing arbiter.
3395 * eval.c (scm_m_define): Bugfix: Check that the object is a
3396 closure before setting the procedure property!
3398 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
3400 * ports.c: Removed `ungetc-char-ready?'.
3402 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
3404 * read.c (scm_init_read): intitialise scm_read_hash_procedures
3405 (idea from Mikael: make it a pair so scm_permanent object only
3407 (scm_read_hash_extend): don't call scm_permanent_object.
3408 (ideas from Mikael): if chr is already in the list, replace its
3409 procedure instead of appending it again. If proc is #f, remove
3411 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
3413 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
3415 * gdbint.c (gdb_read): update scm_lreadr usage.
3417 * load.h: update prototypes.
3419 * load.c (scm_primitive_load, scm_read_and_eval_x,
3420 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
3422 * read.h: add prototype for scm_read_hash_extend. Change args for
3425 * read.c (scm_read_hash_procedures): new variable.
3426 (scm_read_hash_extend): new procedure.
3427 (scm_get_hash_procedure): new procedure.
3428 (scm_lreadr): use scm_get_hash_procedure instead of an argument
3429 for extended # processing.
3430 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
3431 scm_read_token): remove case_i, sharp arguments. Change callers.
3433 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
3435 * read.h (SCM_N_READ_OPTIONS): increase to 3.
3436 (SCM_CASE_INSENSITIVE_P): define.
3438 * read.c: add case-insensitive option to scm_read_opts.
3439 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
3440 to determine whether to convert symbol case.
3441 (default_case_i): definition removed.
3442 * read.c (scm_read_token): if case_i, downcase ic before doing
3445 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3447 * configure.in: Added configuration option `guile-debug'.
3448 Configure with --enable-guile-debug if you want a bunch of extra
3449 functions used for debugging when developing Guile.
3451 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3453 * procs.c (make-cclo): New undocumented debugging procedure: Make
3454 compiled closure with internal procedure PROC and length LENGTH.
3455 Only compiled if GUILE_DEBUG is defined.
3457 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3459 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3461 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3463 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3464 with 3 or more args internally to the evaluator.
3466 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3468 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3469 with 3 or more args internally to the evaluator. This is mainly
3470 because we don't want to pass entry and exit points of the
3471 debug support twice, but it also seems to increase the speed of
3472 the evaluator for such calls (e. g. (+ 1 2 3)).
3474 * backtrace.c (scm_display_application): New procedure:
3475 display-application; Set fancy printing parameters individually
3476 for different types of display (backtrace, error, application).
3477 (These should of course be customizable!)
3479 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3480 clear the CHECK-flags.
3482 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3484 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3486 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3488 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3489 from pairs with a GLOC in the car.
3491 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3492 otherwise `symbol-hash' will behave badly.
3493 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3494 we get segmentation fault!
3496 * symbols.c: Added #include "weaks.h". New functions:
3497 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3498 moved to an extraneous library when we split libguile.)
3500 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3502 * filesys.c (scm_stat): stat now takes fport arguments too as
3503 documented in the manual.
3505 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3507 * debug.c (scm_single_step): Bugfix: Call continuation with
3508 scm_call_continuation instead of throwing to it.
3510 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3512 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3513 argument wasn't declared to be optional.
3515 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3517 * stime.c (scm_init_stime): Add feature "current-time".
3519 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3521 * throw.h: prototype for scm_exit_status.
3522 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3523 args to derive an exit status. Allows (quit) to work from a
3525 (scm_exit_status): new function.
3528 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3530 * eval.c (scm_deval): Removed some old code.
3531 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3533 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3536 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3539 * procs.c: Introduce the existent C function scm_thunk_p at the
3540 Scheme level as well.
3542 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3544 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3545 used from C to easily lookup the value of a symbol in the current
3548 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3550 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3551 scm_init_unif in this file. This will also fix a previous problem
3554 * configure.in: Added AM_MAINTAINER_MODE
3556 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3558 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3561 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3563 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3564 source files that are not always included in libguile but should
3565 have their dependencies calculated by automake. This variable is
3566 recognized by automake, no further magic is needed.
3567 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3568 to deal exclusively with *.lo files, as it seems. The *.o files
3569 are built automatically when the corresponding *.lo file gets
3572 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3574 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3577 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3579 * unif.c (scm_array_set_x): minor change to argument error checking.
3581 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3583 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3584 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3585 They should only be included in the library at configure.in's
3587 (libguile_la_LDADD): Include the appropriate .lo files here.
3588 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3589 so we know when to build them (and their .lo bretheren).
3590 * configure.in (LIBLOBJS): New substituted variable. We let
3591 configure decide which .o files to include in LIBOBJS, and then
3592 put the corresponding list of .lo files in LIBLOBJS. The latter
3593 is what we pass to libtool.
3594 * Makefile.in, configure: regenerated.
3596 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3598 * symbols.c (scm_sysintern0): New function. Contains the core of
3599 old scm_sysintern but doesn't take a second value argument.
3600 (scm_sysintern): Now uses scm_sysintern0.
3601 (scm_sysintern_no_module_lookup): Renamed to
3602 scm_sysintern0_no_module_lookup and doesn't take a second value
3603 argument any longer.
3605 * symbols.h (scm_sysintern0: Added declaration.
3607 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3608 scm_sysintern when interning option keys. Otherwise we risk
3609 destroying the values of already interned variables.
3611 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3612 scheme-level boolean (use SCM_NFALSEP).
3614 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3616 (scm_backtrace): New function. (C version of old function from
3617 boot-9.scm) Motivation: Make it possible to display backtraces
3618 without depending on boot-9.scm. (I'm uncertain if this
3619 motivation is good enough...)
3621 * root.h (scm_root_state): Add member the_last_stack_var.
3622 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3624 * root.c (mark_root): Mark scm_the_last_stack_var.
3626 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3629 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3631 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3632 1. mark_lazy_catch didn't mark the smob.
3633 2. Both functions above have standard variants:
3634 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3635 free_lazy_catch --> scm_free0.
3637 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3639 * throw.c (scm_internal_lazy_catch): New function.
3640 (scm_lazy_catch): Rewritten to use it.
3641 (scm_ithrow): Handle the new lazy catch representation.
3642 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3643 that doesn't have a jmpbuf is a lazy catch clause.
3644 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3645 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3646 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3648 (scm_init_throw): Register the new lazy-catch smob type.
3649 * throw.h (scm_internal_lazy_catch): decl for new function.
3651 * throw.c (scm_internal_catch): Doc fixes.
3653 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3654 configure.in. Including this might cause problems if applications
3655 that link against libguile include their own copies of alloca, but
3656 if they're using autoconf, they should be adding libguile to LIBS
3657 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3658 the copy in libguile, and things will be okay. (I think.)
3660 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3662 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3664 strop.h: move prototypes too.
3666 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3668 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3671 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3672 etc. I deleted them from filesys.c long ago, but didn't
3673 notice they were here too (although ineffective since
3674 sys/stat.h wasn't included).
3676 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3678 * eval.c: Don't define alloca in GCC case. gcc will automatically
3679 use __builtin_alloca if appropriate.
3681 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3683 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3684 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3685 that values of automatic variables are preserved. See comments
3686 for safe_setjmp for details.
3688 Change from Thomas Morgan:
3689 * variable.c: Include eq.h.
3690 (var_equal): New function.
3691 (variable_smob): Use var_equal as the discriminator for variables.
3693 * throw.c (s_throw): Remove extraneous declaration.
3695 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3696 * eval.c: Add necessary CPP cruft to support that.
3697 * configure, Makefile.in, scmconfig.h.in: regenerated.
3699 Change from Thomas Morgan:
3700 * procprop.c (scm_procedure_properties): Convert the Scheme
3701 boolean returned by scm_procedure_p into a C boolean before using
3702 it as a condition for SCM_ASSERT.
3703 (scm_procedure_property): Likewise.
3705 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3706 indications of Unixness.
3709 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3711 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3713 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3715 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3716 "unknown # object" error messages.
3718 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3719 (scm_i_index) and declare it static. Add a 'direction' argument
3720 to indicate what way the search should go.
3721 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3723 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3724 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3726 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3728 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3730 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3731 to avoid clash with various scsh forks.
3733 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3735 The following two changes (ramap.c, throw.c) are motivated by the
3736 apparent unportability of forward declarations of static arrays of
3737 the form `static foo bar[];'.
3739 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3740 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3742 * throw.c (scm_throw): Moved above scm_ithrow.
3744 * options.h: Removed the extern declarations of scm_yes_sym and
3745 scm_no_sym since these are static.
3747 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3749 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3751 * Makefile.am: remove AWK=@AWK@.
3752 Add a rule for generating errnos.list.
3753 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3755 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3756 don't extract errnos, just set a variable (avoids the
3757 need to recompile error.c just because configure is run.)
3759 * unif.h: update prototypes.
3760 * unif.c (scm_uniform_array_read,write): change the offset and
3761 length arguments to start and end, for consistency.
3763 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3765 * ioext.h: update prototypes.
3766 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3767 scm_read_line_x, it's a more general procedure using an
3768 interface from scsh. read-line and read-line! are now defined
3770 Note that the new read-line trims the terminator
3771 by default, previously it was appended to the returned string. An
3772 optional argument specifies how to process the terminator (scsh
3773 compatible). For the old behaviour: (read-line port 'concat).
3774 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3775 returns a pair, but is converted to multiple values if the scsh
3778 socket.h: update prototypes.
3779 * socket.c (scm_recvfrom): for consistency with other procedures,
3780 take start and end as separate optional arguments.
3781 (scm_recv, scm_recvfrom): don't allow the second argument
3782 to be a size, only a buffer. Change the scheme names to
3783 recv! and recvfrom!. Don't return the buffer.
3785 * ioext.h, posix.h: move prototypes too.
3786 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3787 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3788 "read.h" and "unif.h".
3789 * ioext.c: include "chars.h"
3791 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3793 * dynl.c: The dynamic linking and module registration functions
3794 are now defined even when dynamic linking is not available for the
3795 host system. Some of their functionality can be done without
3796 dynamic linking; when it's really needed, they throw errors.
3798 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3800 * configure.in: Only define DYNAMIC_LINKING when one of the system
3801 dependent functions is detected.
3802 * dynl.c (scm_dynamic_func): New function to get the address of a
3803 function in a dynamic object.
3804 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3805 produced by scm_dynamic_func as the thing to call.
3807 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3809 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3810 (scm_register_module_xxx, scm_registered_modules,
3811 scm_clear_registered_modules): New functions.
3813 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3815 * symbols.c (scm_sysintern): Renamed to
3816 scm_sysintern_no_module_lookup.
3817 (scm_sysintern): New function to take the place of the old
3818 scm_sysintern. It uses the current toplevel lookup closure to give
3819 the symbol its value. This is a temporary hack to put packages
3820 like gtcltk into their own module.
3821 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3822 us whether `scm_top_level_lookup_closure_var' has been initialized
3824 * eval.c (scm_init_eval): Set it.
3826 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3828 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3829 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3831 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3833 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3834 scm_sys_dup): deleted: FD capability will be added to other
3836 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3837 scm_fd_free, fd_smob, scm_intern_fd.
3838 (scm_open): renamed from scm_sys_open. Return a port instead of
3839 an FD object. Make the mode argument optional.
3840 (scm_sys_create): deleted, it's just a special case of open.
3841 (scm_init_filesys): move interning of constants O_CREAT etc.,
3842 here (were previously using SCM_CONST_LONG macro).
3843 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3845 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3846 include "fports.h" and <stdio.h>
3847 (scm_stat, scm_select): don't support FD objects.
3849 * error.h: adjust scm_syserror_msg prototype.
3850 * error.c (scm_syserror_msg): take an extra argument for errno.
3851 Using the global value didn't always work, since it could be
3852 reset by procedure calls in the message or args arguments.
3854 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3855 I don't understand why the check was there (and what about the
3858 * strop.c (scm_string_copy): allow shared substrings to be copied.
3860 * unif.h: corresponding change to prototypes.
3861 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3862 recognize two new optional arguments: offset and length. Allow
3863 the port argument to be an integer (file descriptor, for scsh).
3864 Include <unistd.h> for "read" prototype.
3866 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3868 * socket.c: don't include filesys.h.
3870 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3872 * Makefile.am: add AWK=@AWK@ (?)
3874 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3876 Add a rule to generate errnos.c from errnos.
3877 * error.c (scm_init_error): include errnos.c.
3878 * errnos_cnvt.awk: new file, converts the list of errno codes to
3880 * errnos_get.c: new file.
3881 * errnos.default: new file, contains errnos to try if they can't
3882 be extracted from errno.h.
3883 * configure.in: if using GCC, try and extract errno codes from
3887 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3889 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3890 * Makefile.am: Made libguile into a libtool library.
3891 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3892 Set libtool_libs to indicate that libguile is a libtool library.
3893 See guile/ChangeLog for details.
3894 * .cvsignore: ignore "*.lo", the libtool library objects.
3896 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3898 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3899 use htons in getservbyport argument.
3901 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3903 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3904 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3907 * objprop.c (scm_object_property): No need to take the CDR of the
3908 value returned by scm_object_properties, since Aug 20 change.
3910 * configure.in: When checking for struct linger, #include
3911 <sys/types.h> as well as <sys/socket.h>. I've never known
3912 <sys/types.h> to cause any portability problems, and Solaris's
3913 <sys/socket.h> needs it.
3914 * configure: Rebuilt.
3916 I think the Sun compiler has chosen a perverse way to interpret
3917 ANSI declarations combined with K&R definitions. We'll
3918 appease it a little bit. But when it invades France, we fight.
3919 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3920 * print.h (scm_iprlist): Here too.
3921 * numbers.c (scm_divbigdig): Change definition to match
3922 declaration in numbers.h.
3923 * unif.c (scm_makflo): Change definition to match declaration in
3926 * init.c (scm_boot_guile): Don't return the value of
3927 scm_boot_guile_1. This function doesn't return a value;
3928 scm_boot_guile_1 doesn't return a value (or return at all).
3930 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3933 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3934 compile. I have a feeling this function is a bad idea anyway ---
3935 one should always test for features, not systems.
3937 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3938 semicolons. Only pure luck kept this from being noticed earlier.
3940 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3942 * socket.c (scm_recvfrom): Added missing semicolon.
3944 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3946 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3947 the buffer and start and end positions for scsh networking
3950 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3952 * configure.in: Revert previous change to this file; the problem
3953 is due to transient automake weirdness.
3954 * configure: Rebuilt.
3956 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3957 PLUGIN/guile.libs. configure generates the latter from the former.
3958 * Makefile.in: Rebuilt.
3960 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3961 need this if we install scripts, like guile-snarf.
3962 * configure: Rebuilt.
3964 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3966 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3968 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3970 * socket.c (scm_addr_vector): fix faulty scm_listify.
3972 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3974 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3975 style block comment is no longer considered an error.
3977 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3979 * PLUGIN/guile.libs.in: New file.
3980 * PLUGIN/guile.libs: Removed from repository.
3981 * configure.in: Create PLUGIN/guile.libs from
3982 PLUGIN/guile.libs.in. This is for including additonal libraries
3983 needed for dynamic linking.
3984 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3985 instead of PLUGIN/guile.libs.
3987 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3989 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3991 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3992 occurrences of the given element from the list, not just the
3993 first. This is how the Emacs Lisp functions behave, how the
3994 analogous Common Lisp functions behave, and (I believe) how the
3995 older Maclisp functions worked. I realize that this change may
3996 break code, but it seemed better to break it before the Guile
3999 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
4000 Their prototypes were already present in gc.h, but they weren't
4002 (scm_init_storage): Initialize scm_protects.
4003 * root.c (scm_protects): New element of scm_sys_protects.
4005 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
4007 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4009 * libguile.h: Added #include "libguile/net_db.h".
4011 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
4012 30 change. That file is only meant for communication between the
4013 configuration process and load.c. If code linked against libguile
4014 wants to get at the paths mentioned in libpath.h, it can call
4015 functions declared in load.h.
4017 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4019 * libguile.h: Removed #include "libguile/fdsocket.h"
4021 * net_db.c: Added #include <sys/socket.h>.
4023 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
4025 * filesys.c (scm_input_waiting_p): use select in preference to
4026 FIONREAD, since the latter doesn't detect EOF.
4027 Throw error if neither select nor FIONREAD available.
4029 * socket.c (scm_connect): take a port, not a fd object.
4030 (scm_fill_sockaddr): throw an error if fam is not recognised.
4031 (scm_bind): use scm_fill_sockaddr.
4032 (scm_listen): take a port, not a fd object.
4033 (scm_accept): take and return a port. return #f in the car if
4034 address can't be got
4035 (scm_sock_fd_to_port): new procedure.
4036 (scm_socket): use scm_sock_fd_to_port.
4037 (scm_addr_vector): throw error if unrecognised address type.
4038 take an extra argument with the calling procedure name.
4039 (scm_getsockname): take a port. return #f if address can't be got.
4040 (scm_getpeername): take a port. return #f if address can't be got.
4041 (scm_recvfrom): take a port. return #f for address component if can't
4043 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
4044 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
4046 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
4048 * throw.c (scm_internal_catch): Make body funcs and handler funcs
4049 use separate data pointers, to allow them to be designed
4050 independently and reused.
4051 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
4052 Renamed from catch_body, catch_handler, and uncaught_throw; made
4054 (struct scm_catch_body_data): Renamed from catch_body_data; moved
4056 (scm_catch): Use the above.
4057 (scm_throw): Don't bother printing a message for an uncaught
4058 throw; we establish a default handler in init.
4059 * throw.h (scm_internal_catch): Prototype updated.
4060 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
4062 (struct scm_body_thunk_data): New structure, used as data
4063 argument to scm_body_thunk.
4064 * init.c (struct main_func_closure): New structure, packaging up
4065 the data to pass to the user's main function.
4066 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
4067 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
4068 scm_internal_catch to establish a catch-all handler, using
4069 scm_handle_by_message. This replaces the special-case code in
4071 (invoke_main_func): Body function for scm_internal_catch; invoke
4072 the user's main function, using the main_func_closure pointer to
4073 decide what to pass it.
4074 * root.c (struct cwdr_body_data): Remove handler_proc member.
4075 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
4076 (cwdr_handler): Removed.
4078 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4080 * socket.h (SCM_P): update bind prototype.
4081 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
4082 include "feature.h".
4083 (scm_socket): return a port, not a file descriptor object.
4084 include "fports.h" and <unistd.h>
4085 (scm_bind): take a port, not a file descriptor object.
4086 take an extra argument for address args.
4088 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
4089 INADDR_NONE, INADDR_LOOPBACK.
4091 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4093 * init.c: include net_db.h and not fdsocket.h.
4094 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
4096 * Makefile.am: corresponding changes.
4097 * socket.h: renamed from fdsocket.h, fix names.
4098 * net_db.h: renamed from socket.h, fix names.
4099 * socket.c: renamed from fdsocket.c.
4100 remove _sys from procedure names.
4101 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
4102 add "socket" to features list.
4103 * net_db.c: renamed from socket.c.
4104 remove _sys from procedure names.
4105 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
4106 add "net-db" to features list.
4107 include "net_db.h". don't include <sys/socket.h> or
4110 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4112 * tags.h (scm_tags): Removed comma at end of last enumerator.
4114 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
4116 Don't use GCC extensions to allocate space for debugging frames.
4117 (Here he goes again! Why do we put up with this?!)
4118 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
4119 an scm_debug_info structure, not an in-line array of them. Add
4120 'info' member, to say how many vect elements we've used, for eval
4122 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
4123 a new variable debug_info_end to mark the end of vect, instead of
4124 the address of the 'info' pointer itself.
4125 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
4126 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
4127 (SCM_APPLY): Explicitly allocate space for debug.vect.
4128 * debug.c (scm_m_start_stack): Same, for vframe.vect.
4129 * stacks.c: Adjusted for new debug frame structure.
4130 (RELOC_INFO, RELOC_FRAME): New macros.
4131 (stack_depth, read_frames): Use them, and new scm_debug_frame
4132 element 'info', instead of magically knowing that eval frames have
4133 an info pointer sitting after vect.
4134 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
4136 (scm_init_stacks): Formatting tweaks.
4138 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
4140 Give GCC more control flow information, so it can be sure that
4141 variables aren't used uninitialized.
4142 * error.h (scm_error, scm_syserror, scm_syserror_msg,
4143 scm_sysmissing, scm_num_overflow, scm_out_of_range,
4144 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
4145 scm_misc_error): Tell GCC that these functions never return.
4146 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
4147 out the field type, call abort if SCM_ASSERT returns, to placate
4149 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
4150 scm_wta ever returns. We can't handle this case anyway, and this
4151 gives the optimizer more information.
4152 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
4153 scm_wta ever returns.
4155 In some cases, the code is fine, but GCC isn't smart enough to
4156 figure that out; this usually happens when one variable is only
4157 initialized and used when a particular condition holds true, and
4158 we know that condition will never change within a given invocation
4159 of the function. In this case, we simply initialize the variables
4160 to placate the compiler, hopefully to a value which will cause a
4161 crash if it is ever actually used.
4162 * print.c (scm_iprin1): Initialize mw_pos.
4163 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
4164 * throw.c (scm_ithrow): Initialize dynpair.
4165 * unif.c (scm_uniform_vector_ref): Initialize cra.
4166 * struct.c (init_struct): Initialize prot.
4167 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
4169 * strports.c (scm_eval_0str): Don't return uninitialized garbage
4170 if EXPR contains no expressions.
4172 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
4174 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
4175 cause an infinite loop (???). So much for the algebraic
4176 equivalency of variable-sized arrays and alloca...
4178 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
4180 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
4181 a SCM boolean, not a C boolean.
4183 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
4185 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
4186 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
4187 rules for raising scm_mtrigger. Previously, unfortunate but not
4188 unlikely circumstances could result in almost constant invokation
4189 of the gc. Now, this situations should be less likely, but they
4190 are not prevented completely.
4192 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
4194 * numbers.c (scm_fuck): Procedure removed; looks like old test
4196 * numbers.h: Prototype removed.
4198 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
4200 * debug.h (scm_debug_frame): Change `vect' member from an in-line
4201 array to a pointer, to match my Nov 21 change in eval.c.
4203 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4205 * libguile.h: Added #include "libguile/backtrace.h", #include
4206 "libguile/stacks.h".
4208 * strings.c (scm_string scm_make_string scm_string_ref
4209 scm_string_set_x scm_string_equal_p scm_string_append):
4210 Bugfix according to scm patch from Aubrey Jaffer:
4211 Corrected long-standing
4212 (not (eqv? (integer->char 128)
4213 (string-ref (make-string 1 (integer->char 128)) 0)))
4214 bug found by John Kozak <jk@noontide.demon.co.uk>.
4216 * strports.c, strports.h: Make scm_eval_0str return the value of
4217 the last expression evaluated (previously, it returned void).
4219 * strports.c, strports.h: New function: scm_read_0str. Does what
4222 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4224 * simpos.c (scm_getenv): return #f if string can't be found in the
4225 environment instead of throwing an exception, for compatibility
4226 with numerous other systems.
4228 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
4230 * Makefile.am (.c.x): Use guile-snarf.
4231 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
4233 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
4235 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4237 * backtrace.c (scm_display_error_message): Made non-static, and
4238 renamed from display_error_message.
4239 * backtrace.h (scm_display_error_message): Added extern decl.
4240 * throw.c (uncaught_throw): Use it to display the error message.
4242 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
4244 * inet_aton.c: Use #if 0, not #ifdef 0.
4246 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
4248 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
4249 to convert the returned value.
4250 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
4251 the offset argument.
4253 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4255 Add new interface to catch/throw, usable from C as well as
4257 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
4258 (scm_internal_catch): New function, replaces...
4259 (scm_catch_apply): Deleted.
4260 * throw.c (scm_catch_apply): Deleted; replaced with a more general
4261 mechanism which is a bit more code, but can be used nicely from C
4262 and implement the Scheme semantics as well.
4263 (scm_internal_catch): This is the replacement; it's named after
4264 the analogous function in Emacs.
4265 (scm_catch): Reimplemented in terms of the above.
4266 (struct catch_body_data, catch_body, catch_handler): New
4267 functions, used by scm_catch.
4268 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
4269 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
4270 support for new cwdr.
4272 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
4275 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
4277 * acconfig.h: Added DYNAMIC_LINKING symbol.
4278 * configure.in: Add option and checks for dynamic linking.
4279 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
4280 dynl.h: New files for dynamic linking support.
4281 * Makefile.am (libguile_a_SOURCES):
4283 (modinclude_HEADERS): Added "dynl.h".
4284 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
4286 * init.c (scm_boot_guile_1): Call
4287 scm_init_dynamic_linking to initialize dynamic linking support.
4289 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
4291 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
4292 (as we Schemers say). It needs to be global, so that I can tweak
4293 it for the proper operation of unexec.
4294 (scm_boot_guile_1_live): New variable, see above.
4296 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
4298 * guile-snarf.sh: Removed.
4299 * PLUGIN/guile.libs: Added dependency for -lm.
4300 * acinclude.m4: Renamed from aclocal.m4.
4301 * PLUGIN/greet: Removed.
4302 * Makefile.am, aclocal.m4: New files.
4303 * configure.in: Updated for Automake.
4305 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
4307 * eval.c (scm_definedp): Use top_level_lookup_closure_var
4308 and not top_level_lookup_thunk_var.
4310 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
4312 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
4314 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
4316 * eval.c (scm_definedp): Incompatibly changed to be a builtin
4317 Scheme function, instead of syntax. Single argument is now a
4320 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4322 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
4323 scm_ra_divide): Properly terminate statements passed as arguments
4324 to IVDEP macros. (Thanks to Bernard Urban.)
4326 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
4327 with non-constant sizes. (Thanks to Bernard Urban.)
4329 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4331 It's an "eval closure", not an "eval thunk." A thunk is a
4332 function of no arguments.
4333 * root.h (struct scm_root_state): Renamed
4334 top_level_lookup_closure_var from top_level_lookup_thunk_var.
4335 (scm_top_level_lookup_closure_var): Renamed from
4336 scm_top_level_lookup_thunk_var.
4337 * root.c (mark_root): Uses changed.
4338 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
4339 * init.c (scm_start_stack): Uses changed.
4340 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
4341 Change scheme-visible name to *top-level-lookup-closure* from
4342 *top-level-lookup-thunk*.
4344 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
4346 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
4347 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
4349 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
4351 * gc.c (struct scm_heap_seg_data): Doc fixes.
4353 * gc.c (scm_gc_sweep): Empty all segments' freelists before
4354 sweeping. Then, prepend each segment's free cells to its
4355 freelist, rather than wiping out the old value. (Thanks to Marius
4358 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
4359 scm_check_freelist, scm_debug_newcell): New functions and
4360 variables, for debugging freelist problems.
4361 * pairs.h (SCM_NEWCELL): New debugging version added.
4362 * gc.h (scm_debug_newcell): Added extern declaration, used by
4363 debugging version of SCM_NEWCELL.
4365 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4367 On some systems <libc.h> conflicts with <unistd.h>, and should not
4368 be #included at all.
4369 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
4370 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
4371 * configure.in: Call it.
4372 * posix.c, filesys.c: Use its results to decide whether or not to
4374 * configure, scmconfig.h.in: Rebuilt with autoconf and
4377 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4379 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
4380 pointer to the stdio stream before calling scm_setbuf0, so the
4381 latter will be able to retrieve it. I'm surprised this didn't
4382 segfault earlier. (Thanks to Christopher Lee.)
4384 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4386 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
4389 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4391 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
4392 number of stack narrowing specifier pairs. The first specifier in
4393 a pair controls inner border, the second the outer border. A
4394 number means cut that number of frames, a procedure object means
4395 cut until that object is found in operator position in a frame.
4397 * root.c (cwdr): Bugfix.
4399 * read.c: Recording of positions disabled by default.
4401 * procs.c (scm_closure_p): New function.
4403 * posix.c (scm_tmpnam): New function.
4405 * load.c: Added #include "throw.h".
4406 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
4409 * load.c, load.h (scm_read_and_eval_x): New function.
4411 * eval.c: Renamed debug option "deval" to "debug".
4413 (scm_eval_x): `eval!' is no longer accessible from the scheme
4414 level. Motivation: We can't allow operations which introduce
4415 glocs into the scheme level. Guile's type system can't handle
4416 these as data. Use `eval' or `read-and-eval!' as replacement.
4418 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
4419 SCM_CONSP since this is a macro!; Set vframe.prev to
4420 scm_last_debug_frame instead of 0. In this way we can look
4421 "above" the virtual start stack frame if we wish.
4422 (scm_debug_hang): New function: Useful for debugging Guile in
4423 certain tricky situations. Will probably be removed later...
4425 * debug.h: Changed semantics of debug option "backtrace". This
4426 option now only indicates whether we want automatic backtrace at
4429 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4431 * ports.c: #include "filesys.h"
4432 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
4434 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
4435 Motivation: This is system specific code which is related to file
4436 I/O. It also may use select. Added code by Gary Houston to
4437 detect presence of character in stdio buffers.
4439 * libguile.h: #include "libguile/libpath.h"
4441 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4442 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4443 SCM_SITE_DIR; Install libpath.h among the other include files.
4445 * load.c, load.h (scm_sys_package_data_dir): New function.
4447 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4449 * stacks.h: Bugfix: Don't use tail-array length field as stack
4450 length field! This screwed GC.
4452 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4454 * _scm.h: Added #ifndef around definition of macros min and max.
4456 * __scm.h: Added hooks for threads to plugin to in ints protection
4457 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4458 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4459 the main code in these macros duplicated and spread over multiple
4460 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4461 SCM_THREAD_SWITCHING_CODE.
4463 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4465 * snarf.h: New file.
4466 * guile-snarf.sh: New file.
4467 * Makefile.in (inner_h_files): Added snarf.h
4468 (ancillary, install, uninstall, distclean): Added actions for
4470 (.c.x): Use guile-snarf.
4471 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4472 (gen_c_files): Note that these depend on guile-snarf.
4473 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4474 now in "snarf.h". Added #include "snarf.h" to get them.
4475 * libguile.h: Added #include "snarf.h".
4476 (Patches applied and tweaked by Jim Blandy.)
4478 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4480 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4481 standards suggest against providing prototypes for system
4482 functions. Thanks to Greg Troxel.
4484 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4486 * strports.c (scm_eval_0str): New function.
4487 #include "read.h", to get prototype for scm_read.
4488 * Makefile.in (strports.o): Update dependencies.
4489 * strports.h: New prototype.
4491 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4492 scheme name from "int?" to "integer?". It seems to do the job.
4493 * numbers.h: Rename prototype too.
4494 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4497 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4498 scm_num_eq_p): Rename these according to R4RS conventions: call
4499 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4500 to making libguile R4RS compliant without ice-9...
4502 * load.c (scm_sys_search_load_path): Search for files under all
4503 extensions listed in the %load-extensions variable. If FILENAME
4504 is absolute, return it unchanged, without searching the load path.
4505 (scm_loc_load_extensions): New variable, pointing to
4506 %load-extensions' value cell.
4507 (scm_init_load): Initialize it, and the value it points to.
4508 (scm_primitive_load_path): Improve error reporting.
4510 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4511 of new Scheme variable %load-hook.
4512 (scm_primitive_load): Apply %load-hook to filename.
4514 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4516 * configure.in: add tests for figuring out whether buffered data
4517 is available in a FILE structure, which is needed by char-ready.
4519 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4522 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4523 exceptions using misc_error instead of syserror. It seems a bit
4524 odd to throw an exception if a string can't be found in the
4525 environment, but it's consistent with open-file, stat etc.
4526 (simpos.h): remove sys_ from getenv.
4528 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4529 occurs, throw an error instead of returning errno. Return value
4531 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4533 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4535 * filesys.c (scm_stat2scm): derive file type and permissions from
4536 the stat mode and append them to the returned vector.
4537 There isn't much overhead in doing this and it avoids the need to
4538 work with S_IRUSR et al. in Scheme.
4539 Define symbols scm_sym_regular etc.
4540 (scm_init_filesys): don't intern S_IRUSR etc.
4542 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4543 and s_primitive_load_path.
4545 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4547 * error.h: don't declare error symbols. prototype for scm_misc_error.
4549 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4552 * error.c: use SCM_SYMBOL to set up error keys.
4553 scm_misc_error: new procedure.
4555 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4557 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4558 between `#!' and `!#' is ignored.
4559 (skip_scsh_block_comment): New function.
4561 * feature.c (scm_set_program_arguments): New argument, FIRST.
4562 * feature.h: Update prototype.
4563 * init.c (scm_boot_guile_1): Pass new argument to
4564 scm_set_program_arguments.
4566 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4568 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4569 (scm_boot_guile): Call scm_set_program_arguments here, later than
4570 the old initialization.
4572 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4573 initialization procedure.
4574 - Delete in, out, err arguments; there are other perfectly good
4575 ways to override these when desired.
4576 - Delete result argument; this function shouldn't ever return.
4577 - Rename init_func argument to main_func, for less confusion.
4578 - Delete boot_cmd argument; main_func is more general.
4579 -Add 'closure' argument, to help people pass data to main_func
4580 without resorting to global variables.
4581 - Abort if reentered; don't bother returning an error code.
4582 - Call scm_init_standard_ports to set up the default/current
4583 standard ports; no need to pass them to scm_start_stack.
4584 - Remove code to evaluate the boot_cmd, and start the repl; let
4585 the user do something like that in main_func if they want.
4586 - Remove code to package up a return value; main_func can do any
4588 - Call exit (0), instead of returning.
4589 (scm_start_stack): Don't initialize the I/O ports here; that's
4590 weird. Delete in, out, err arguments. Move guts to
4591 scm_init_standard_ports, scm_stdio_to_port.
4592 (scm_init_standard_ports): New function, to set up current and
4593 default standard ports.
4594 (scm_start_stack, scm_restart_stack): Make these static.
4595 * init.h (scm_boot_guile): Adjust declaration.
4596 (scm_start_stack, scm_restart_stack): Remove externally
4597 visible declarations for these.
4598 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4600 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4601 written out several times in scm_start_stack.
4602 * fports.h: New declaration for the above.
4604 * feature.c (scm_set_program_arguments): New function.
4605 * feature.h: New declaration for the above.
4607 * ports.c: Formatting tweak.
4609 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4611 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4612 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4613 for obtaining the address of a car or cdr field. Motivation:
4614 &SCM_CXR make assumptions about the internal structure of the
4617 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4618 Motivation: see SCM_CXRLOC.
4620 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4621 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4622 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4623 Motivation: Safer use. Some other macros are defined in terms of
4624 these operations. If these are defined using the SCM_SETCXR
4625 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4626 to inefficiency and an <e1> with side-effects could potentially
4627 break. Also, these particular operations are heavily utilized in
4628 the garbage collector. In unoptimized code there will be a
4631 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4632 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4633 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4634 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4635 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4636 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4637 vports.c: Cleaned up use of pairs: Don't make any special
4638 assumptions about the internal structure of selectors and
4639 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4640 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4641 (Among other things, this change makes it easier to build Guile
4642 with certain compilers which have problems with casted lvalues.)
4644 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4646 * stacks.c: Improve selection of relevant stack frames when making
4647 a stack object. Introduce one level of indirection in the stack
4648 object to make it possible to "narrow" to a certain region of the
4649 stack. This facilitates making use of more clever algorithms (not
4650 implemented) for selecting relevant frames and gives a cleaner
4651 design since selection of frames can be done independently of
4652 extraction of frames from the real stack.
4653 (scm_stack_id): Also take #t as argument which means look at
4656 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4657 Turn n_tail into an integer directly representing current number
4658 of frames in stack. Add field tail.
4660 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4662 * debug.c (scm_make_memoized): Made it available at scheme level.
4663 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4664 SCM_NIMP before applying heavier predicates in argument checking.
4665 (scm_local_eval): Also take memoized object as argument.
4667 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4668 aren't created with zero length, but should such a strange
4669 creature suddenly turn up...
4671 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4673 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4674 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4676 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4678 * variable.c (scm_make_variable): Make the name hint optional, as
4680 (anonymous_variable_sym): Renamed from variable_sym. All uses
4683 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4684 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4685 of scm_primitive_load_path was also changed to
4686 "primitive-load-path", from "%try-load-path". Callers changed.
4687 We'd like to respect the convention that a function named
4688 "try-mumble" should behave just like the function called "mumble",
4689 but return #f instead of signalling some error.
4690 * load.h: Rename prototypes.
4692 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4694 * print.c (make_print_state, grow_print_state), print.h: Modified
4695 the print state representation: Don't use a tail array for
4696 recording of circular references. Resizing of the print state
4697 structure invalidates the print state pointer. To avoid passing
4698 around an indirect print state reference to all printing
4699 functions, we instead let the print state reference a resizable
4702 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4704 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4705 Don't crash when passed an improper list terminated by a
4706 non-immediate value.
4708 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4710 Allocate data for structures on an eight-byte boundary, as
4711 required by the tagging system.
4712 * struct.c (alloc_struct): New function.
4713 (scm_make_struct, scm_make_vtable_vtable): Call it.
4714 * struct.h (scm_struct_n_extra_words): Bump to 3.
4715 (scm_struct_i_ptr): New "field".
4716 * gc.c (scm_gc_sweep): When we need to free the data, use the
4717 information stored by alloc_struct to find the beginning of the
4718 block allocated to the structure, so we can free it.
4720 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4722 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4725 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4726 (scm_debug_info): New member: id.
4728 * stacks.c: Stacks are now represented as structs; Stacks have an
4729 id given to them by `start-stack'.
4730 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4732 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4733 Changed stack representation.
4735 * debug.c (scm_procedure_name): Try procedure property `name' for
4736 compiled closures aswell.
4738 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4740 * eval.c: scm_i_name moved to gsubr.c
4741 (scm_m_define): Record names of all kinds of procedure
4742 objects. (Earlier, only closures were recorded.)
4744 * procprop.h: Added declaration of scm_i_name.
4746 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4747 (scm_make_gsubr): Record names of compiled closures.
4749 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4751 * debug.c, debug.h: Removed obsolete code.
4753 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4754 stacks.c: Renamed regs --> scm_contregs.
4756 * print.c (scm_free_print_state): Cleanup print state before
4757 returning it to pool. It is better to do it here than in
4758 scm_prin1 since scm_prin1 is called often.
4760 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4761 s_set_source_property_x): Check that first argument is a pair or a
4764 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4765 scm_i_line, scm_i_column and scm_i_breakpoint global.
4767 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4768 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4771 * debug.h: Added debug object smob declaration and macro
4774 * configure.in: Build with backtrace.o and stacks.o if debug
4777 * Makefile.in: Added entries for new files: backtrace.c,
4778 backtrace.h, stacks.c and stacks.h.
4780 * symbols.c (scm_sym2ovcell): Fixed documentation.
4782 * _scm.h (min, max): Added.
4784 * async.c: Moved `min' macro to _scm.h.
4786 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4787 SCM_BACKTRACE_INDENT.
4789 * eval.c: Added new debug options `maxdepth' and `indent'.
4791 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4793 * print.h: Added selector SCM_PRINT_STATE.
4795 * print.c: New functions: scm_make_print_state,
4796 scm_free_print_state.
4798 * print.h: Added declarations for scm_make_print_state,
4799 scm_free_print_state.
4801 * debug.c (scm_m_start_stack): New acro.
4803 * debug.h: Small cleanup.
4805 * init.c (scm_boot_guile_1): Moved scm_init_debug below
4808 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4810 * __scm.h, alist.c, alist.h, append.c, append.h, appinit.c,

4833 More prototype-related changes from Marius Vollmer:
4834 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4835 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4836 * ports.h (ptobfuns): Added prototypes. This means some casting in
4838 * fports.c: Added casts for initializations, since the functions
4839 are defined to take FILE * as their stream argument, not SCM.
4840 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4841 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4842 to `char *str_data' to conform to prototype.
4844 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4846 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4848 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4850 * stime.c, stime.h: use SCM_P method.
4852 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4854 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4855 be given at least two arguments. Insist that lst's last element
4856 be a list, but don't make any requirements of its predecessors.
4858 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4860 * eval.c (scm_nconc2last): Revert last change; there seems to be
4861 other stuff going on here.
4863 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4865 * eval.c (scm_nconc2last): Make sure that each element of lst
4866 (which is a list of argument lists, except for the tail) is a
4867 proper list, i.e., finite and terminated by '().
4869 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4871 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4874 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4875 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4878 * vectors.c (scm_make_vector): Fill vectors with the undefined
4879 value, to help make Guile Scheme code more portable to other
4882 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4883 * symbols.h, tags.h: Doc fixes.
4885 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4887 * async.c (scm_take_signal): Doc fixes.
4889 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4891 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4892 want to subtract it from the modulus; we just want to leave it
4895 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4897 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4900 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4902 * throw.c (scm_catch_apply): Finished implementation of
4905 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4907 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4909 (scm_init_filesys): set "i/o-extensions" feature.
4912 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4914 * Makefile.in (root.o): Correct dependencies.
4916 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4918 * Makefile.in: Added dependency entry for root.o.
4920 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4921 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4923 * init.c (scm_start_stack): Set initial root continuation number
4926 * procs.c: New function: scm_thunk_p.
4928 * procs.h: Added declarations of scm_thunk_p.
4930 * root.c: Renamed `call-with-new-root' -->
4931 `call-with-dynamic-root'.
4932 (cwdr): Removed allocation of new root state. This should be done
4933 separately by use of scm_make_root.
4934 (scm_apply_with_dynamic_root): New function: Does what it
4935 sounds like. Needed when spawning threads.
4937 * root.h: Added member last_debug_frame to root state.
4938 Added #include "libguile/debug.h"
4940 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4941 arguments. The motivation is that code in root.c needs catch
4942 functionality, and we want to avoid code duplication.
4943 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4944 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4945 handlers that run without popping the stack into the dynwind
4948 * throw.h: Added prototypes for scm_catch_apply and
4951 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4953 * root.h (scm_root, scm_set_root): Decouple thread support details
4954 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4955 SCM_SET_THREAD_LOCAL_DATA.
4957 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4958 and tortoise scanning loop.
4960 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4962 * Makefile.in: Rebuild dependencies.
4964 * libguile.h: #include "libguile/print.h" before "smob.h", since
4965 the latter uses the print_state structure.
4967 * throw.c (scm_ithrow): Use the correct variable when checking to
4968 see if a given element of scm_dynwinds is a valid catch.
4970 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4971 structure, abort; don't just silently ignore the garbage.
4973 * _scm.h: #include "print.h" here, since it seems to be used just
4975 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4976 strports.c, unif.h: Don't #include "print.h".
4978 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4980 * feature.h (scm_loc_features): Removed external declaration.
4981 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4983 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4985 * feature.c (scm_init_feature): Added threads feature (needs to be
4986 initialized here, since features doesn't exist when
4987 scm_init_threads is called).
4989 * libguile.h: Added #include "libguile/../threads/threads.h".
4990 (This is a kludge to get thread support working. This should be
4993 * configure.in, acconfig.h: Added flags for thread support.
4995 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4998 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4999 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
5002 * _scm.h: Added conditional #include "threads.h"
5004 * __scm.h (SCM_ASYNC_TICK): Added call to macro
5005 SCM_THREADS_SWITCHING_CODE.
5007 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
5008 allocate the basic dynamic root object.
5009 (scm_boot_guile): Added call to scm_init_root.
5011 * root.c, root.h: Added root smob.
5012 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
5013 functions: Implements dynamic roots mostly according to spec in
5014 SCM manual. Main difference is that the second argument is a
5015 throw handler rather than an error "thunk".
5017 * root.h: Added declaration of scm_init_root.
5019 * root.c: Added #include "genio.h", #include "smob.h", #include
5020 "pairs.h", #include "throw.h", #include "dynwind.h", #include
5022 (scm_init_root): Added #include "root.x".
5024 * throw.c: Added #include "stackchk.h"
5025 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
5026 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
5027 can be used in scm_call_with_new_root; Added reenabling of stack
5028 checking when catching a throw.
5030 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
5032 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
5034 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
5035 element is not found, as per R4RS.
5037 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
5039 * list.c: Doc fixes throughout.
5041 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
5043 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
5044 declare the char * to be const. Avoids a warning in rgx.c.
5046 * ports.h: spelling fix.
5048 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
5051 * load.c (scm_sys_try_load_path): throw an error if file not found
5052 (like it says it in NEWS).
5054 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
5056 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
5057 PROPS slot to '(), not #f; it's an empty alist.
5059 * throw.h, throw.c: Use SCM_P instead of #if hair.
5061 Remove special support for uncaught throws; see throw.c for
5063 * throw.c (uncaught_throw): New function.
5064 (scm_ithrow): Call uncaught_throw if we don't find a throw
5065 target; don't mess with scm_bad_throw_vcell.
5066 (scm_bad_throw_vcell): Variable deleted.
5067 (scm_init_throw): Don't initialize it.
5069 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
5072 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
5074 * numbers.c (scm_istr2int): If the number is short (as most
5075 numbers are), just call scm_small_istr2int to deal with it.
5076 (scm_small_istr2int): New function, created by un-#ifdefing the
5077 non-bignum version of scm_istr2int and renaming it.
5079 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
5081 * load.c (scm_sys_try_load): don't check whether value returned
5082 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
5083 Change the Scheme name from %try-load to primitive-load.
5085 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
5086 Can avoid passing a message, allowing it to be derived in the
5087 error handler (e.g., if we want to throw to the key both from
5090 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
5092 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
5093 references now have a new appearance which is more compact and
5094 also gives a clue about what the target of the reference is.
5095 By setting parameters in the print state, more fancy printing can
5096 be achieved. This is used by the (not yet commited) backtrace
5099 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
5101 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
5104 * print.c: Added #include "struct.h". Removed function
5107 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
5108 scm_iprin1. Removed prototype for scm_prlist.
5110 * arbiters.c (prinarb),
5111 async.c (print_async),
5112 debug.c (prindebugobj, prinmemoized),
5113 eval.c (prinprom, prinmacro),
5114 filesys.c (scm_fd_print, scm_dir_print),
5116 mallocs.c (prinmalloc),
5117 numbers.c, numbers.h (scm_floprint, scm_bigprint),
5118 smob.h (scm_smobfuns),
5119 srcprop.c (prinsrcprops),
5121 unif.c, unif.h (scm_raprin1, rapr1),
5122 variable.c (prin_var): Changed argument `int writing' to
5123 `scm_print_state *pstate'.
5125 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
5126 that it will be called before scm_init_print.
5128 * print.c (scm_prin1): Print states are now allocated when calling
5129 scm_prin1 and then passed around to all printing functions as an
5130 argument. A cache `print_state_pool' enables reuse of print
5132 (scm_make_print_state): New function.
5133 (scm_iprin1): Adaption to print states.
5134 (scm_iprlist): An initial "hare and tortoise" scan brings down
5135 time complexity to O (depth * N). (Better time complexity will be
5136 achieved when the printing code is completely rewritten.)
5138 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
5140 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
5141 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
5142 it gets done whether or not the cache variable has a value.
5144 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5146 Distinguish #f and ().
5147 * __scm.h: #undef SICP.
5148 * pairs.h (SCM_EOL): Delete this definition, equating it with
5150 * tags.h (SCM_EOL): Give it a new definition here; I think I found
5151 the value it used to have. Doc fixes, too.
5153 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
5155 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
5156 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
5157 Lord's implementation of structs, allowing for tail arrays as
5158 described in the manual. Also fixed some bugs. (Both the interface
5159 and the implementation should be improved.)
5161 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
5163 * print.c, print.h: Closures now print like #<procedure foo (x)>.
5164 People who whish to see the source can do `(print-enable 'source)'.
5165 Removed #ifdef DEBUG_EXTENSIONS.
5167 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5169 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
5170 integer (assuming for now accepting an integer is a good thing).
5172 * error.c, fports.c: replace use of %S in lgh_error args with %s.
5173 %S will be used instead for write'ing arguments.
5175 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
5176 asserts. fix a few other asserts.
5177 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
5178 scm_uniform_vector_ref, scm_array_set_x,
5179 scm_dimensions_to_unform_array): change args in
5180 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
5181 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
5182 scm_substring_fill_x): likewise.
5183 gsubr.c (scm_gsubr_apply): likewise.
5184 eval.c (SCM_APPLY): likewise.
5186 * eval.c (4 places): replace scm_everr with lgh_error or
5189 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
5190 scm_memory_error): new procedures.
5191 scm_everr: deleted. can use scm_wta, dropping first two args.
5192 scm_error: convert NULL subr to SCM_BOOL_F.
5194 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
5197 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
5200 * error.c, error.h: new error keys: scm_arg_type_key,
5201 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
5203 scm_wta: reimplement using lgh_error instead of scm_everr.
5205 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
5207 * gdbint.c: scm_lread now has one more argument.
5209 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
5210 scm_port_\1; Added mutator scm_set_port_filename_x (used when
5211 loading source from non-file ports, which, e. g., happens when
5212 using the Emacs interface).
5214 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
5217 * read.c: Added code for recording of positions of source code
5218 expressions; New functions: recsexpr, scm_lreadrecparen;
5219 _scm_make_srcprops --> scm_make_srcprops
5220 (scm_flush_ws): Removed updating of positions counters. This work
5221 is already done by scm_gen_getc
5223 * read.h: Added prototype for scm_lreadrecparen
5225 * print.c: Added #include "alist.h"
5227 * eval.c: Added #include "hash.h"
5229 * eq.c: Added #include "ramap.h"
5231 * options.c: Documentation fixes.
5233 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
5234 (scm_init_srcprop): Adjusted size of initial source-whash. Name
5235 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
5236 --> scm_make_srcprops
5238 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
5239 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
5240 function calls in the definition of the whash access macros.
5242 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
5244 * init.c (scm_boot_guile): Add level of indirection to
5245 scm_boot_guile_1() to ensure that stack base pointer is properly
5246 initialized. There was no guarantee that variable i was the
5247 highest/lowest variable on stack (i.e. the call frame of
5248 scm_boot_guile was not completely protected from gc).
5250 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
5252 * ports.h (scm_port_table): put back file_name, it will be used to
5253 support debugging. Undo related changes in fports.c, ioext.c,
5256 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5258 * ports.h (scm_port_table): remove file_name member for now, it seems
5260 * fports.c (scm_open_file): don't set file_name in PTAB.
5261 (prinfport): don't use file_name in PTAB.
5262 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
5263 * ports.c (scm_add_to_port_table): don't intialize file_name.
5264 (scm_port_file_name): remove for now.
5265 * gc.c (scm_gc_mark): don't mark PTAB file_name.
5267 * fports.h (scm_mkfile): prototype deleted.
5268 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
5270 * debug.c, unif.c: use scm_out_of_range instead of
5271 wta for range errors (ASSERT still needs work).
5273 * error.c, error.h (scm_out_of_range): new procedure.
5275 * error.c, error.h (scm_out_of_range_key): new key.
5277 * posix.c (scm_sync): #else was missing.
5279 * error.c, error.h: append _key to names scm_num_overflow and
5282 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
5283 of consing an empty list.
5284 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
5285 of macros, saves code and string space.
5286 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
5287 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
5288 lower case. Rename scm_syserror_m to scm_syserror_msg.
5289 error.h: prototypes for new procedures.
5291 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
5293 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
5295 * error.c, error.h: setup scm_num_overflow key.
5297 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
5298 Remove definition of SCM_OVSCM_FLOW.
5300 * fports.c (scm_open_file): use SCM_SYSERROR_M.
5302 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
5303 explicit message and args.
5305 * error.c, error.h, __scm.h: change system_error_sym to
5308 * error.c (system_error_sym): remove leading %% from the Scheme name
5311 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
5313 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5315 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
5316 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
5317 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
5318 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
5319 renamed. (These were introduced by unsupervised name
5322 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5324 * print.c: Added code for detection of circular references during
5325 printing. (init_ref_stack, grow_ref_stack): New functions. Added
5326 a hook for printing of closures (accessible via print options).
5327 This leads to a split of calls to scm_iprin1 into two classes:
5328 elementary print operations (e. g. the code which prints a smob)
5329 still use scm_iprin1 while top level calls (like scm_display) use
5330 scm_prin1. scm_prin1 begins by clearing the data structure used
5331 to record reference information.
5333 * print.h: Added declarations of scm_prin1 and scm_prlist.
5335 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
5337 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
5339 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
5341 * error.c (err_head): scm_iprin1 --> scm_prin1
5343 * debug.c: Adjusted header comment.
5347 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
5349 * strerror.c: Doc fix.
5351 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5353 * gdbint.c (gdb_read): Now possible to run during GC.
5354 (unmark_port, remark_port): New functions.
5356 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
5358 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
5359 of allocating a new string object. Also, increase size by
5360 the factor 2 instead of 1.5.
5362 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
5364 * __scm.h (SCM_P): Corrected to run under traditional C.
5366 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
5369 * async.c: Calls to scm_sysintern corrected.
5371 * async.h (scm_async_clock): Redundant declaration removed.
5373 * continuations.c (scm_dynthrow): Redundant declaration removed.
5375 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
5376 Definition typos corrected.
5378 * debug.h: Missing declarations of functions in debug.c added
5381 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
5382 Missing declarations to functions in eval.c added.
5384 * filesys.c: Possibly uninitialized variable rv.
5386 * gc.h (scm_object_addr, scm_unhash_name): Missing
5387 declarations of functions defined in gc.c added.
5389 * genio.c: Possible typos str_data -> wstr_data. ???
5391 * genio.c: Possibly unintended shadowing of local variable
5392 `int c' (gotos out of scope of inner `c'). ???
5394 * init.c: Uninitialized `SCM last' may be used.
5396 * ioext.h: (scm_sys_isatty_p): Typo.
5398 * list.h (scm_list_head): Missing prototype for function in
5401 * numbers.c (scm_two_doubles): Changed from extern to static
5402 (is used only within numbers.c).
5404 * numbers.h: Repeated declarations removed.
5406 * ports.h (scm_close_all_ports_except): Declaration for the
5407 function defined in ports.c added.
5409 * posix.h: Missing declarations added.
5411 * procs.h (scm_make_subr_opt): Missing declaration added.
5413 * socket.h (scm_sys_gethost): Missing declaration added.
5415 * socket.h: Redundant declarations removed (they are in fdsocket.h).
5417 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
5418 Missing declarations added.
5420 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
5422 * struct.c: Uninitialized variable `SCM answer' may be used.
5424 * unif.c (l2ra): Declaration prototype.
5426 * unif.c (scm_array_equal_p): Dummy definition removed (it is
5427 defined in ramap.c).
5429 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
5430 Redundant declarations removed (they are in ramap.h).
5432 * variable.h (scm_make_udvariable,
5433 scm_make_undefined_variable): Declaration corrected to
5434 correspond variable.c.
5436 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
5437 Missing declarations added.
5439 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5441 * Makefile.in (distclean): Don't forget to delete fd.h.
5443 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5445 * fd.h.in, tags.h: Trivial cleanups.
5447 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5448 marksweep.h just declared functions from gc.c.
5449 * gc.h, libguile.h: Don't #include "marksweep.h".
5450 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5451 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5452 dependencies updated.
5454 * libguile.h: Don't #include "files.h"; it's been deleted.
5456 * files.c (scm_sys_delete_file): Moved to filesys.c.
5457 File is now empty; deleted.
5459 * filesys.c: scm_sys_delete_file is now here. Remove
5460 #if's; they seem to rely on remnants of an old portability
5461 regimen. If the problems come up again, solve them properly,
5462 using autoconf. Specifically: Don't test M_SYSV, and #define
5463 remove to be unlink if it's #defined; don't use remove just
5464 because HAVE_STDC_HEADERS is #defined.
5465 * filesys.h: Add declarations for scm_sys_delete_file.
5466 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5467 files.o, files.h, files.c, and files.x.
5468 * init.c: Don't #include "files.h", and don't call scm_init_files.
5470 Use SCM_P instead of PROTO; the latter intrudes on the user's
5472 * params.h: Deleted; definition of SCM_P moved to...
5473 * __scm.h: ... here, where it replaces PROTO macro.
5474 * libguile.h, smob.h: Don't #include "params.h".
5475 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5476 smob.h: Fix prototypes accordingly.
5477 * Makefile.in: Update dependencies.
5478 (inner_h_files): Remove params.h.
5480 * gc.c: #include "gc.h"; every module should include its header,
5481 to let the compiler cross-check the declarations against the
5484 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5485 simpos.h: #include "libguile/__scm.h".
5487 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5489 * init.c: Don't forget to #include smob.h and init.h.
5490 * Makefile.in: Dependencies updated.
5492 * smob.h: Use PROTO instead of #if __STDC__.
5494 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5496 * __scm.h: Doc fixes.
5498 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5499 <angles>; this allows `make depends' to work properly.
5501 * libguile.h: #include smob.h and pairs.h before the others; they
5502 define typedefs used by other headers.
5504 C files should #include only the header files they need, not
5505 libguile.h (which #includes all the header files); the pointless
5506 recompilation was wasting my time.
5507 * Makefile.in (all .o dependency lists): Regenerated.
5508 * libguile.h: Don't try to get a definition for size_t here...
5509 * __scm.h: Do it here.
5510 * _scm.h: Since this is the internal libguile header, put things
5511 here that all (or a majority) of the libguile files will want.
5512 Don't #include <libguile.h> here; that generates dependencies on
5513 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5514 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5515 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5612 * weaks.c: Get "weaks.h".
5614 * stackchk.h: #include "libguile/debug.h",
5616 * print.h, read.h: #include "options.h", since everyone who uses
5617 either of these files will need that.
5619 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5620 anyone who uses this file will need them to define the smob
5621 printing functions. Also, get markers.h, since people will need
5622 to #define the mark functions.
5624 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5625 * ports.h: ... to here.
5627 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5628 don't rely on archaic C default type rules.
5630 * fports.h: #include "libguile/ports.h", since you need that in
5631 order to parse this.
5633 * genio.h: #include "libguile/print.h", because you need that to
5634 parse this; don't bother #including "ports.h", since print.h gets
5637 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5639 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5640 this; it's now a reference to an element of *scm_root.
5642 * debug.h: Don't #include "options.h"; the compiler won't be able
5643 to find that once the headers are installed; instead, #include
5644 "libguile/options.h".
5645 * gc.h: Same, with marksweep.h.
5646 * mbstrings.h: Same, with symbols.h.
5647 * scmhob.h: Same, with _scm.h.
5648 * smob.h: Same, with params.h.
5650 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5651 C files; there's no need for this, and it forces recompilations
5654 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5656 * error.c (scm_error): declare scm_error_callback.
5658 * error.h: prototype for scm_error_callback.
5660 * __scm.h: define lgh_error.
5661 (SCM_SYSERROR): redefine using lgh_error.
5663 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5665 * error.c (scm_error): new procedure.
5667 * error.h: prototype for scm_error.
5669 * Makefile.in (install): install scmconfig.h from the current
5670 directory, not $(srcdir).
5672 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5674 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5675 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5676 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

5682 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5683 vports.h, weaks.h: #include "libguile/__scm.h", not
5684 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5685 dependencies are within libguile properly.
5687 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5689 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5690 when scmconfig.h doesn't exist.
5692 * load.c (scm_sys_try_load): Correct spelling.
5694 * feature.c (scm_loc_features): Make this static.
5696 * Makefile.in (libpath.h): Omit trailing slash from path. We
5697 shouldn't require it of users, so why put it here?
5699 Move code to initialize and search %load-path from ice-9 to C
5700 code, so we can use the load-path to find the ice-9 boot code;
5701 this makes it easier to run Guile without installing it. See
5702 corresponding changes in guile/Makefile.in.
5703 * feature.c: Move stuff concerned with the load path to load.c.
5704 (scm_compiled_library_path): Deleted.
5705 Don't #include libpath.h here.
5706 * feature.h: Don't mention scm_compiled_library_path.
5707 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5708 <sys/stat.h>, and <unistd.h> (if present).
5709 (R_OK): #define if the system hasn't deigned to.
5710 (scm_loc_load_path): New variable.
5711 (scm_init_load_path, scm_sys_search_load_path,
5712 scm_sys_try_load_path): New functions.
5713 (scm_init_load): Initialize scm_loc_load_path to point to the
5714 value cell of the Scheme %load-path variable.
5715 * load.h: Add declarations for scm_sys_search_load_path,
5716 scm_sys_try_load_path.
5717 * init.c: Call scm_init_load_path.
5718 * Makefile.in (feature.o, load.o): Dependencies updated.
5720 * load.c, load.h: Rewrite using PROTO macro.
5722 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5724 * gc.c (scm_cellp): New function: C predicate to determine if an
5725 SCM value can be regarded as a pointer to a cell on the heap.
5727 * gc.h: Added declaration of scm_cellp.
5729 * gdb_interface.h: New file: The GDB interface header from the GDB
5732 * gdbint.c: New file: GDB interface.
5734 * gdbint.h: New file: GDB interface.
5736 * libguile.h: Added #include <libguile/gdbint.h>.
5738 * init.c (scm_boot_guile): Added scm_init_gdbint.
5740 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5741 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5742 found if object files and source are kept separate).
5744 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5746 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5748 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5750 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5751 TK_SRC_DIR; they're not relevant any more.
5753 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5754 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5756 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5758 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5759 search path, so we can find the <libguile/MUMBLE.h> headers.
5761 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5763 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5764 implicit in the .c.o rule.
5765 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5768 Put the library path in a header file, instead of passing it on
5769 the command line in every compilation.
5770 * Makefile.in (libpath.h): New target.
5771 (feature.o): Depend on libpath.h.
5772 (clean): Delete libpath.h.
5773 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5774 * feature.c: ... #include "libpath.h" here.
5775 * .cvsignore: Ignore libpath.h.
5777 Don't install the unwashed masses of Guile header files in the
5778 main #include path; put most of them in a subdirectory called
5779 'libguile'. This avoids naming conflicts between Guile header
5780 files and system header files (of which there were a few).
5781 * Makefile.in (pkgincludedir): Deleted.
5782 (innerincludedir): New variable; this and $(includedir) are enough.
5783 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5784 (installed_h_files): Divide this up. Now this variable lists
5785 those header files which should go into $(includedir) (i.e. appear
5786 directly in the #include path), and ...
5787 (inner_h_files): ... this new variable says which files appear in
5788 a subdirectory, and are referred to as <libguile/mumble.h>.
5789 (h_files): List them both.
5790 (install): Create innerincludedir, not pkgincludedir. Put
5791 the installed_h_files and inner_h_files in their proper places.
5792 (uninstall): Corresponding changes.
5793 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5794 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5795 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5796 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5797 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5798 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5799 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5800 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5801 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5802 vports.h, weaks.h: Find __scm.h in its new location.
5803 * __scm.h: Find scmconfig.h and tags.h in their new locations
5804 (they're both "inner" files).
5806 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5808 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5810 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5812 * posix.c: Doc fixes.
5814 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5816 * socket.c: Don't include a prototype for inet_aton; just use a
5817 K&R style declaration, to avoid warnings but minimize the chance
5818 of conflicts with the system.
5820 On NextStep, <utime.h> doesn't define struct utime, unless we
5821 #define _POSIX_SOURCE before #including it.
5822 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5823 * acconfig.h: New comment text for above CPP symbol.
5824 * configure.in: Call it.
5825 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5827 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5829 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5830 testing for __EMX__.
5832 * posix.c: #include <libc.h>, if it exists.
5834 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5835 don't even know if the latter exists.
5837 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5838 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5839 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5841 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5843 (scm_init_posix): Use them when initializing the Scheme constants
5846 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5848 * Makefile.in (libdir, includedir, bindir): Use the
5849 autoconf-supplied values, instead of deriving them ourselves.
5850 (pkgincludedir, datadir, pkgdatadir): New variables.
5851 (install, uninstall): Put the header files in a special
5852 subdirectory, not in the main search path.
5854 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5855 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5857 * Makefile.in (IMPLPATH): Deleted; never used.
5859 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5860 on the Tcl/Tk source any more.
5861 (INCLUDE_CFLAGS): Remove references to the above.
5863 * Makefile.in (version.o): Corrected dependencies.
5865 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5867 * libguile.h: #include "version.h"
5869 * init.c (scm_boot_guile): Call scm_init_version.
5870 * gscm.c (gscm_run_scm): Call scm_init_version.
5872 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5873 GUILE_VERSION): AC_DEFINE these.
5874 (acconfig.h): #undef the above symbols.
5876 * Makefile.in (libobjs): Add version.o.
5877 (installed_h_files): Add version.h.
5878 (c_files): Add version.c.
5879 (gen_c_files): Add version.x.
5880 (version.o): New rule.
5881 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5882 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
5883 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
5884 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
5885 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
5886 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
5887 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
5888 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
5889 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
5890 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5891 weaks.o): Add version.h to dependency lists.
5892 (markers.o): Remove duplicate rule.
5894 * version.h: New file.
5896 * version.c: New file.
5898 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5900 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5901 array; use it appropriately. Since GCC is quite happy to
5902 subscript functions, it never warned us about this; we should use
5903 -Wpointer-arith in the future. I guess we never tested
5906 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5908 * socket.c: Doc and copyright fixes.
5910 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5912 * debug.c: Fixed and improved gdb support.
5914 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5916 * socket.c: Added declaration of inet_aton to avoid compiler
5917 warning. (Hope this solution is correct.)
5919 * stime.c: Added declaration of ftime. (This is missing in
5922 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5924 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5926 * Makefile.in (c_files): add strerror.c.
5928 * strerror.c: new file from Emacs' sysdep.c.
5929 maybe configure should also check for sys_errlist.
5931 * configure.in (AC_REPLACE_FUNCS): add strerror.
5933 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5935 * debug.c (scm_init_debug): Added initialization for
5936 scm_evaluator_traps.
5938 * debug.h, debug.c: Various name changes.
5939 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5940 "debug-options-interface". See commentary in options.c.
5942 * options.h, options.c: Options now have documentation strings.
5943 Also added a long explanatory commentary.
5945 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5948 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5949 last_debug_info_frame is now updated in all cases.
5951 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5954 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5956 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5957 Added option STACK_CHECKING.
5959 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5961 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5963 * __scm.h: Removed symbols for debugging support.
5965 * acconfig.h: Added symbols for debugging support.
5967 * configure.in: Added user option for debugging support.
5968 --enable-debug will include the debugging code into libguile.a.
5970 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5971 scm_relocate_chunk_to_heap.
5973 * debug.c: New file: low-level debugging support. It also
5974 includes support for debugging with gdb. (The extensions to gdb
5975 are written by Per Bothner at Cygnus.)
5977 * debug.h: New file: low-level debugging support.
5979 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5980 argument pairs. Extensive modifications to the debugging
5981 evaluator. Added "SECTION:" commentaries to clarify what happens
5982 when, during double compilation. Renamed EVALIMP --> EVALIM.
5983 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5984 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5985 the beginning of the file. New procedure: scm_unmemocopy.
5986 Added some global state variables needed by the debugging
5987 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5988 check_entry, check_apply, check_exit, debug_options and
5989 evaluator_traps. New acro: undefine.
5991 * eval.h: Renamed EVAL --> XEVAL.
5993 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5994 --> scm_make_weak_key_hash_table.
5996 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5997 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5999 * libguile.h: Conditionally include debug.h
6001 * objprop.c (scm_object_properties, scm_set_object_properties_x):
6002 scm_object_properties shouldn't return handle. `handle' now gets
6003 initialized in scm_set_object_properties_x. scm_object_properties
6004 doesn't any longer create an entry in scm_object_whash.
6006 * options.c: New file: handling of run time options.
6008 * options.h: New file: handling of run time options.
6010 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
6012 * print.c: New procedure: scm_print_options
6014 * print.h: Defines for print options.
6016 * read.c: New procedure: scm_read_options
6018 * read.h: Defines for reader options.
6020 * root.h: Added scm_source_whash among scm_sys_protects.
6022 * srcprop.c: New file: source properties.
6024 * srcprop.h: New file: source properties.
6026 * throw.c (jbsmob): Jump buffers are now correctly allocated.
6027 (Bug found by A. Green.)
6029 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
6031 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
6033 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
6035 * libguile.h: #include "objprop.h"; I guess this was forgotten.
6037 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
6038 and should be called by the final client.
6040 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
6042 * gc.h: Use the PROTO macro when declaring functions.
6043 * gc.c: Use the PROTO macro when declaring static functions.
6044 Remove the CPP hair around function definitions.
6046 * gc.c (scm_init_storage): Initialize scm_asyncs.
6048 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
6049 preprocessor symbol; "__scm.h" is where it might get #defined.
6050 * __scm.h: Similar: #include <scmconfig.h> before testing
6053 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
6055 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
6057 * init.c (scm_boot_guile): Add init_func argument; call
6058 (*init_func) instead of calling scm_appinit; it's ucky to
6059 hard-code names for the user's procedures.
6060 * init.h (scm_boot_guile): Adjust declaration.
6062 * __scm.h (PROTO): New macro, for declaring functions with
6065 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
6066 eliminate all the __STDC__ conditionals.
6067 (scm_boot_guile): Add declaration.
6068 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
6069 Remove __STDC__ conditionals around function definitions; the
6070 declarations in init.h will provide the same information, more
6073 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
6074 complain about it in the error message; the error message is
6075 adequate without that note, and there's nothing the user can do
6078 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
6080 * Makefile.in (ancillary): Drop def.sed.
6082 * posix.c (scm_init_posix): Use numeric values, rather than
6083 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
6084 F_OK. The symbols aren't available on some systems, and I'm
6085 pretty sure their values are fixed by common widespread practice.
6086 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
6088 More functions unavailable on some systems.
6089 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
6090 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
6092 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
6093 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
6094 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
6095 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
6096 stub that signals an error as the #else.
6098 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
6100 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
6102 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
6104 * unif.c: include ramap.h.
6106 * read.c (endif): case_insensative_p renamed case_insensitive_p.
6108 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
6110 * ports.c: include sys/ioctl.h.
6112 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
6114 * configure.in: check for sys/ioctl.h.
6116 * ports.c: include <malloc.h> not "malloc.h".
6118 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6120 * fports.c: remove ttyname and tmpnam declarations.
6122 * posix.c: fewer ttyname declarations.
6124 * fports.c: include <string.h> not "string.h".
6126 * init.c, ioext.c: include string.h and unistd.h.
6128 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6130 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
6131 genio.c, simpos.c, vports.c: include string.h.
6133 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
6135 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
6137 (scm_addr_buffer_size): change type from scm_sizet to int.
6138 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
6139 from scm_sizet to int.
6141 * error.c: include unistd.h.
6143 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
6146 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
6148 * __scm.hd, def.sed: deleted.
6150 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
6152 Changes for NeXT, suggested by Robert Brown.
6153 * configure.in: Call AC_TYPE_MODE_T.
6154 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
6155 NeXT. Put header file list in alphabetical order.
6156 * configure, scmconfig.h.in: Regenerated.
6157 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
6159 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
6162 * acconfig.h: New file, providing documentation for the CPP
6163 symbols defined in configure.in
6164 * acconfig-1.5.h: Removed; superceded by the above.
6166 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
6168 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
6170 * fports.c (scm_open_file): don't return #f, throw error.
6172 * ioext.c (fileno): renamed from %fileno.
6173 (soft-fileno): deleted.
6175 * ports.c (scm_port_revealed): don't need to check for -1 from
6177 (scm_set_port_revealed_x): return unspecified, not #f.
6179 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
6181 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
6183 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
6185 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
6187 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
6189 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
6190 This is necessary on Ultrix, and doesn't hurt portability.
6192 * Makefile.in (dist-dir): New target, implementing a new dist system.
6193 (installed_h_files): Put in alphabetical order.
6194 Remove duplicate entries for markers.h and unif.h.
6195 (c_files): Remove duplicate entries for markers.c.
6196 (ancillary): Renamed from anillery; all uses changed. Remove
6197 PLUGIN; it's a directory, and needs special treatment in dist-dir.
6198 Remove all the ../doc/* files; doc/Makefile.in handles that.
6200 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
6202 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
6203 every if must have an else, or else the whole command has a
6204 non-zero exit code whenever the if's condition is false.
6206 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
6208 * posix.c: include string.h.
6210 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
6212 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
6215 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
6216 Remove leading % from scheme names.
6217 Do not return error values, call SCM_SYSERROR or similar.
6219 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
6221 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
6223 * struct.c (scm_init_struct): new file.
6225 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
6227 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
6228 (scm_list_head): added list-head for rapidly chopping argument
6229 lists off of longer lists (and similar).
6231 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
6233 * objprop.c (scm_object_property): assq the cdr of the whash
6234 handle for obj, not the handle itself.
6236 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
6238 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
6239 weak hash tables last of all marking to avoid an obscure gc bug.
6240 WARNING: circular lists stored in a weak hash table will hose us.

6463 initialization to fix a race condition.
6465 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

6492 The weird symbol syntax is also a bit bogus (emacs doesn't quite
