1 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3 * eval.c (scm_copy_tree): Copy source properties if existent.
5 * debug.c (scm_start_stack): Copy source when evaluating. (If we
6 don't, we may end up passing memoized source to a transformer.)
8 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
10 * stack.c (get_applybody): Help function which lookups the first
11 body form of the apply closure.
12 (read_frames): Prevent the source of the first form of the apply
13 closure from being recorded. This would only be confusing.
15 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
16 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
18 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
20 * stacks.c (read_frame): Bugfix: Removed lingering `else'
22 (read_frames): Use SCM_MACROEXPP.
24 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
26 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
27 don't contain interesting information since all arguments are
28 present in the frame which applies the compiled closure anyway.);
29 Skip the transformer application frames.
31 * print.c (scm_iprin1): Print gsubrs as primitives.
33 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
35 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
37 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
38 that we can identify these in a backtrace. (This change doesn't
39 introduce any significant speed penalty.)
41 * eval.c: Added note about `serial-map' using scm_map.
43 * read.c, read.h (scm_read_options, scm_read_opts): Removed
44 readline options. They should reside in their own options array.
46 * readline.c, readline.h (scm_readline_options,
47 scm_readline_opts): Moved readline options here.
49 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
51 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
52 SCM_ROCHARS instead of SCM_CHARS.
54 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
55 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
57 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
59 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
60 This is quite important since the latter clears the
61 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
62 every single character read...
64 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
66 * print.c (scm_iprin1): Removed suspect looking (and indeed
67 malevolent) semicolon after test for user supplied closure print
68 procedure. (Thanks to Telford Tendys.)
70 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
71 (scm_memq, scm_memv, scm_member): Do argument checking *before*
72 starting to search the list. Removed call to sloppy_mem_check.
74 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
75 procedures: Same as scm_delq_x et al, but delete maximally one
78 * options.c (scm_options, scm_init_options): GC-protect option
79 values of type SCM. (Thanks to Telford Tendys.)
81 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
83 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
84 make sure that there always is a "real" scm_lookupcar.
86 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
88 * read.c, read.h (history-length, history-file): New read options.
89 (scm_read_options): Stifle history to history length.
91 * readline.c (scm_read_history, scm_write_history): New
94 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
96 * eval.h (scm_macro_eval_x): Removed declaration.
98 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
99 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
100 Renamed and made global.
102 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
103 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
105 * evalext.c, evalext.h: New files. Contain non-R5RS things
106 having to do with evaluation.
108 * evalext.c (scm_serial_map): New procedure: Version of `map'
109 which guarantees that the procedure is applied to the lists in
111 (scm_m_sequence_to_list): New syntax: Version of `begin' which
112 returns a list of the results of the body forms instead of the
113 result of the last body form.
114 (scm_definedp, scm_m_undefine): Moved from eval.c
116 * evalext.h (scm_m_sequence_to_list): Added declaration.
118 * macros.c, macros.h: New files.
119 (scm_procedure_to_syntax, scm_procedure_to_macro,
120 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
121 scm_macro_name, scm_macro_transformer): Moved from eval.c
122 (scm_make_synt): Moved from eval.c
124 * procs.c, procs.h (scm_procedure_documentation): Moved from
127 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
130 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
132 * debug.c, print.c: Added #include "macros.h".
134 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
136 This change adds the ability to use `unread-char' multiple times
137 without interspersed reads and adds the new procedure
138 `unread-string'. The change is optimized for the common case of
139 unreading a single character. This is also the reason behind the
140 choice to store characters in the port itself: in most cases no
141 extra malloc is required.
143 The amount of code in some macros in ports.h has been increased to
144 the extent that they would fit better as C functions, but, since
145 this code belongs to the port representation, such functions
146 should be placed in ports.c which would cause calls back and forth
147 between ports.c and genio.c. That is not good for performance.
148 Also, keeping them as macros allows the compiler to do some
149 optimizations which are needed to make the current interface
150 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
152 One benchmark (Guile startup time) indicates an increase of
153 loading speed of 1%. Another (reading (using `read') boot-9.scm
154 10 times) shows no change in performance.
156 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
157 made to find a beautiful solution.)
159 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
160 (SCM_TRY_CLRDY): New macro: Only clear the first unread
161 character. (SCM_CLRDY clears all.)
162 (SCM_N_READY_CHARS): New macro: Returns number of unread
163 characters in a port. Returns wrong answer if SCM_CRDYP is false.
164 (struct scm_port_table): New fields: `entry' contains port table
165 index, `cp' points to last unread char, `cbuf' is the buffer for
166 unread chars, `cbufend' points after end of the character buffer.
168 * ports.h, ports.c (scm_unread_string): New procedure.
169 (scm_grow_port_cbuf): New function.
171 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
173 (scm_generic_fgets), fports.c (local_fgets): Use a loop
174 to read unread characters. Use SCM_TRY_CLRDY instead of
177 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
179 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
181 * genio.c, genio.h (scm_ungets): New function.
183 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
186 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
188 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
189 declarations. (Thanks to Russ McManus.)
191 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
193 * numbers.c (num2long): As a software archeologist, I'm proud of
194 this finding! :) Preliminary dating suggests an almost 4 year old
195 remnant from the SCM ancestor. The sample has been removed from
196 the finding site and is now safely stored in the repository.
198 * numbers.h: Removed prototype for num2long.
200 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
202 * gh_data.c (gh_scm2doubles): Make it possible to pass result
204 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
205 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
206 * gh.h: Updated and added prototypes.
208 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
210 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
212 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
214 * guile-snarf.in: Never generate an empty file. (Thanks to
217 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
218 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
219 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
220 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
221 gh_new_procedure5_0): Specify argument types, to appease C++
222 compilers. (Thanks to Brad Bowman.)
224 Bug reports from Russ McManus:
225 * guile-snarf.in: If the CPP environment variable is set, use that
226 as the C preprocessor, instead of the preprocessor autoconf
228 * snarf.h (SCM_PROC): Cast the function pointer passed to
229 scm_make_gsubr, to satisfy C++.
231 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
232 Use the handler passed, instead of ignoring it and using
233 gh_standard_handler. (Thanks to Etienne Bernard.)
235 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
237 * ports.h: Put text after #endif in comment. (Thanks to Nicolas

260 * script.c (scm_compile_shell_switches): Define
261 use-emacs-interface in the root module, so the repl code can see
262 it. See today's change to top-repl in ice-9/boot-9.scm.
264 * filesys.c (set_element, get_element): Make sure that `element'
265 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
266 Boekemeier and Jorgen "forcer" Schaefer.)
268 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
270 * chars.c (scm_charnames): In ASCII character name table, make
271 newlines print as #\newline by default, not #\nl.
273 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
274 alphabetical order. Oh thrills. But it helps me know how far
275 along in the compilation I am.
276 * Makefile.in: Regenerated.
278 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
280 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
281 #bytes(...) to #y(...), and syntax for short vectors from
282 #short(...) to #h(...). This may seem nutty, but, like the other
283 uniform vectors, byte vectors and short vectors want to have the
284 same print and read syntax (and, more basic, want to have read
285 syntax!). Changing the read syntax to use multiple characters
286 after the hash sign breaks with the conventions used in R5RS and
287 the conventions used for the other uniform vectors. It also
288 introduces complexity in the current reader, both on the C and
289 Scheme levels. (The Right solution is probably to change the
290 syntax and prototypes for uniform vectors entirely.)
292 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
294 Don't use local_fgets on sockets; ftell doesn't work on sockets.
295 (Thanks to Jorgen "forcer" Schaefer.)
296 * ports.h (SCM_NOFTELL): New flag.
297 * fports.c (local_fgets): If it's set, use the generic fgets.
298 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
300 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
302 * script.c (scm_compile_shell_switches): Add handling of -q switch
303 (inhibit loading of user init file).
304 (scm_shell_usage): Add usage text for -q switch.
305 (scm_compile_shell_switches): Always load user init file first if
308 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
310 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
311 and is now broken under NetBSD. I can't fathom what it's trying
312 to do, so I've replaced it with something that I do understand,
313 which seems to work, and which isn't broken on NetBSD. "Progress?
314 You Decide." (Thanks to Perry Metzger.)
316 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
317 signed/unsigned comparison.
319 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
321 Warning fixes from Greg Harvey:
322 * unif.c (scm_array_set_x): initializer for pos
323 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
324 * struct.c (scm_struct_ref, scm_struct_set_x): Added
325 initializers for field_type, since EGCS so desparately wants to
327 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
328 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
329 when GUILE_DEBUG is defined.
330 * dynwind.h (scm_wind_chain): Same.
331 * ports.h (scm_pt_size, scm_pt_member): Same.
332 * print.h (scm_current_pstate): Same.
333 * procs.h (scm_make_cclo): Same.
335 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
337 Handle short and long long uniform arrays properly. (Thanks to
339 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
340 raeql_1): Add cases for scm_tc7_svect (short vectors) and
341 scm_tc7_llvect (long long vectors).
343 Change the way libguile and boot-9.scm are timestamped, to try to
344 get rid of these spurious mismatch warnings. Now both
345 libguile/versiondat.h and ice-9/version.scm are generated directly
346 by the configuration process, rather than having version.scm
347 generated directly, and libguile/versiondat.h generated by the
348 Makefile, which is generated by configure. It seems that
349 sometimes the Makefile would change, but versiondat.h depends on
350 Makefile.in, not Makefile, so it wouldn't get rebuilt.
351 * Makefile.am (versiondat.h): Target removed; this is generated
352 directly by the configure script now.
353 (BUILT_SOURCES): Remove versiondat.h.
354 * versiondat.h.in: New file, transformed by the configure script
356 * Makefile.in: Regenerated.
358 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
359 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
360 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
361 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
362 if we want to use them in a header file some day, we can. (Thanks
365 * stime.c (scm_get_internal_real_time): Do the arithmetic using
366 SCM numbers, so we won't have rollover problems; the range of a
367 signed long in milliseconds is about 25 days. (Thanks to Karl
370 Don't redefine sleep and usleep; fix this problem now.
371 * coop.c (sleep, usleep): Remove declarations; we don't use or
372 redefine these any more.
373 (scm_thread_usleep, scm_thread_sleep): New functions which do the
374 job of usleep and sleep in a thread-friendly way. We can use
375 these in the rest of Guile. Define versions for systems both with
377 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
378 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
379 we're just using it, not redefining it, we can use a K&R style
381 (sleep): Declare this, too, if the system hasn't.
382 (scm_sleep, scm_usleep): Use scm_thread_sleep and
383 scm_uthread_sleep if they're available; otherwise, just call the
385 * scmconfig.h.in: Regenerated.
387 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
389 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
391 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
393 * threads.c: Doc fix.
395 The argument type of usleep varies from system to system,
396 as does the return type. We really shouldn't be redefining usleep
397 at all, but I don't have time to clean that up before the 1.3.
398 release. It's on the schedule for afterwards. (Thanks to Julian
400 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
402 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
403 * scmconfig.h: Regenerated.
405 * simpos.c (scm_software_type): Procedure deleted. This isn't the
406 right way to handle system variation. Autoconf's approach is the
408 * simpos.h (scm_software_type): Declaration deleted.
410 * script.c (scm_find_executable): Don't test if unix is #defined
411 here; first, NetBSD doesn't #define it, and second, it's the wrong
412 way to go about these things. (Thanks to Perry Metzger.)
413 (dld_find_executable): Delete this MSDOS support code. This isn't
414 the way we want to support this; it needs to be rethunk at a
417 * genio.c (scm_do_read_line): Don't just politely check that the
418 line was either non-empty or EOF. Abort if it's empty and not
421 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
423 * scmconfig.h.in: Regenerated.
425 * libguile.h: Don't omit the dynamic linking functions. (Thanks
428 * genio.c (scm_do_read_line): Count lines correctly when the file
429 doesn't end in a newline.
431 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
433 * genio.c (scm_do_read_line): Maintain the line count correctly.
434 (Thanks to Harvey J. Stein and Greg Harvey.)
436 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
439 * numbers.c (big2str): Protect t from garbage collection until
440 we're done. (Thanks to Gary Houston.)
442 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
444 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
446 * Makefile.in: Regenerated.
448 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
449 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
452 Do magic to mix reads and writes on stdio FILE-based ports.
453 (Thanks to Christian Lynbech.)
454 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
456 (pre_read, pre_write): New functions.
457 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
458 local_fputs): Call them.
459 (local_fflush): Mark the port as ready for reading and writing.
460 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
461 flags on new port objects. This might not be accurate --- who
462 knows what state the FILE * is in when we get it --- but it won't
463 do extraneous calls to fflush or fseek, so it's no worse than the
464 behavior before this change.
465 * ports.h: Add comment.
467 Centralize the creation of port objects based on stdio FILE * in
468 fports.c; don't just throw them together anywhere.
469 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
470 what the rest of Guile wants. Don't set the revealed count;
471 that's only appropriate for stdin, stdout, stderr.
472 (scm_standard_stream_to_port): This function does set the revealed
474 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
475 not scm_stdio_to_port.
476 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
477 * fports.c (scm_open_file): Same.
478 * posix.c (scm_pipe): Same.
479 * socket.c (scm_sock_fd_to_port): Same.
480 * ioext.c (scm_fdopen): Same.
481 (scm_freopen): Moved from here to...
482 * fports.c (scm_freopen): ... here. This is really something that
483 munges the internals of an fport, so it should go here.
484 * fports.h (scm_stdio_to_port): Adjust prototype.
485 (scm_standard_stream_to_port, scm_freopen): New protoypes.
486 * ioext.h (scm_freopen): Prototype removed.
488 * filesys.c (set_element, get_element): This can work on both pipe
489 and file ports, so use SCM_FPORTP to typecheck, instead of testing
492 * scmconfig.h.in: Regenerated.
494 Change the definition of the functions in scm_ptobfuns so that
495 they get passed the port object, not the port's stream.
496 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
497 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
498 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
499 Pass the port itself to the scm_ptobs function.
500 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
501 scm_generic_fgets): Same.
502 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
503 getc_void_port, fgets_void_port, close_void_port): Just change the
504 argument names; these functions don't really do anything.
505 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
506 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
507 port as an argument, and use SCM_STREAM to get the stdio FILE *.
508 Also, use prototyped definitions, and get rid of the extra
510 (scm_fptob, scm_pipob): We don't need casts here any more.
511 * strports.c (prinstpt): Use prototype declarations.
512 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
513 and use SCM_STREAM to get the string info. Also, use prototyped
514 definitions, and get rid of the extra declarations.
515 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
518 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
519 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
521 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
522 scm_fgets, for consistency.
523 (scm_fptop, scm_pipob): References updated.
525 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
527 Include the source location in error messages for scripts.
528 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
529 stack is still there when we catch the error.
530 * throw.c (handler_message): If we are handling an error with a
531 message, then put together the proper arguments and call
532 scm_display_error, instead of scm_display_error_message. That
533 displays source location, if it can find it.
535 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
537 * gc.c (scm_unprotect_object): Change this so that calls to
538 scm_protect_object and scm_unprotect_object nest properly.
539 (scm_protect_object): Doc fixes.
541 * strings.c (scm_string_set_x): Require the argument to be a
542 writable string, not a substring or a symbol.
543 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
544 (Thanks to John Redford and Charbel Jacquin.)
546 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
548 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
550 * eval.c (safe_setjmp): Remove this misunderstanding.
551 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
554 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
556 * libguile.h: Mark these as C declarations, for compilation by C++
559 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
560 __cplusplus clause. I seriously doubt this ever worked the way
561 the author seems to have intended.
563 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
565 Utterly needless cleanups to hopelessly messy code.
566 * ports.c: Doc fixes.
567 (scm_fflush): Moved to ...
568 * genio.c (scm_fflush): ... here, amongst all the other port
569 method invocation functions.
570 * genio.h, ports.h: The prototype moves too.
572 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
574 * backtrace.c (display_error_body): The current frame does not
575 always have a parent frame; consider a function called directly
576 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
579 * alloca.c (alloca): Undo yesterday's changes, and simply call
580 malloc directly for storage, and abort if we don't get what we
581 want. The situation is much simpler --- just call malloc. Emacs
582 has bizarre/evil requirements (signal handlers might malloc unless
583 you set this global flag, so you have to set the flag around all
584 calls to malloc) which we are certainly not going to conform to,
585 so we can do the simple and obvious thing.
587 * coop.c (coop_condition_variable_wait): Make this function
588 static. It's only useful internally --- you should never just
589 wait on a condition variable.
590 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
592 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
594 * unif.c (scm_array_set_x): Accept any kind of number as an
595 element for a uniform vector of doubles. This is more consistent
596 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
598 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
599 works; I can't conveniently test it myself. (Thanks to Dvid
600 Tillman for the bug report.)
604 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
605 from here, not from scm_compile_shell_switches (which is a pretty
606 dumb place to do it).
607 (scm_load_startup_files): New function.
608 (scm_ice_9_already_loaded): Variable moved to here from script.c.
609 * script.c (scm_compile_shell_switches): Don't load the startup
611 (scm_ice_9_already_loaded): Variable moved.
612 * init.c (scm_load_startup_files): Prototype for new function.
613 * gh_init.c (gh_enter): Doc fix.
615 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
617 Some anti-warning changes from Greg Harvey.
618 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
619 warnings when it doesn't understand our NORETURN declarations in
621 * posix.c (scm_mknod): Similar.
623 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
625 * posix.c (scm_getpwuid): If we can't find an entry, return our
626 own message, instead of using scm_syserror --- the getpwMUMBLE
627 functions don't set `errno' to anything interesting.
629 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
631 Get rid of warnings from the cooperative threading system.
632 * threads.h (scm_single_thread_p, scm_yield,
633 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
634 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
635 scm_wait_condition_variable, scm_signal_condition_variable): Add
636 prototypes for these Scheme-visible functions.
637 * coop-defs.h (coop_next_runnable_thread,
638 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
639 Prototypes for these here, even though they're from iselect.c.
640 (coop_condition_variable_wait, coop_join): Add prototypes.
641 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
642 scm_threads_free_condvar): Make these smob functions static.
643 * coop-threads.h (coop_init): Give this a real prototype.
644 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
645 (coop_next_runnable_thread): No need to provide prototype; it's in
648 * scmconfig.h.in: .detarenegeR
650 * iselect.c, threads.c: Doc fixes.
652 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
654 * Makefile.in: Regenerated with a patched automake, to get
655 dependency generation right when using EGCS.
657 * inet_aton.c (inet_aton): Add prototype, to remove compiler
658 warning. (Thanks to Robert Pluim.)
660 * inet_aton.c (inet_aton): Reassure the compiler that the
661 arguments to the <ctype.h> macros are all unsigned characters, not
664 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
666 Getting rid of more warnings...
667 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
668 today's change to ../configure.in.
669 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
670 * scmconfig.h.in: Regenertaded.de.,.__
671 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
672 (scm_localtime, scm_mktime): Use a const char * to manipulate the
675 * readline.c: Doc fix.
676 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
677 * readline.h (scm_filename_completion_function): Add prototype.
678 (scm_init_readline): Make this into a prototype.
680 * readline.c (scm_filename_completion_function): Use SCM_PROC to
681 declare this, instead of calling scm_make_subr manually.
683 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
685 * readline.h (scm_init_readline): Add prototype for this.
686 (scm_init_readline): Make this a real prototype.
688 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
690 Warning fixes from Maciej Stachowiak:
691 * backtrace.h (scm_display_application, scm_backtrace): Add
693 * debug.c (scm_m_start_stack): Make this function static.
694 * fluids.h (scm_fluid_p): Add prototype.
695 * procprop.c (scm_i_procedure_arity): Make this function static.
696 * regex-posix.c (scm_regexp_error_msg): Make this function static.
697 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
698 * root.h (scm_dynamic_root): Add external prototype.
699 * scmsigs.h (scm_usleep): Add external prototype.
700 * script.h (scm_init_script): Use prototype, not K&R decl.
701 * stacks.h (scm_stack_id): Add external prototype.
702 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
704 1998-09-30 Mark Galassi <rosalia@cygnus.com>
706 * gh.h: took out the definitions of vset and vref, since they are
707 replaced by the proper vector routines that correspond to the R4RS
710 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
712 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
713 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
714 third argument, a C expression that should result in a SCM value,
715 which is used to initialize the variable. Reimplemented
716 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
719 * version.h (scm_libguile_config_stamp): Add prototype.
720 (From Maciej Stachowiak.)
722 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
724 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
725 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
727 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
729 * print.c (scm_iprin1): Rather than having one i, and using it in
730 several places, declare a fresh i local to each block where it is
731 used, and give it a signedness appropriate to its use in each case.
734 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
737 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
738 signed/unsigned clashes.
740 * posix.h (scm_tmpnam): Added prototype.
742 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
743 scm_make_subclass_object): Add external prototypes.
745 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
746 comparison is okay here.
748 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
750 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
751 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
753 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
756 * load.c (swap_port): Make this function static.
758 * load.c (scm_search_path): Make max_path_len and max_ext_len
759 unsigned, since they're compared against string sizes.
761 * load.c (init_build_info): Make i unsigned.
763 * ioext.h (scm_read_line): Add prototype.
765 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
766 scm_hash_fn_remove_x): Make hash bucket index local variable k
767 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
768 accurately as possible.
770 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
771 comparisons, and range checking to make sure those casts are
774 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
775 signed/unsigned comparisons.
777 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
778 avoid signed/unsigned comparisons.
779 * smob.h (scm_numsmob): Change extern declaration to match.
781 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
782 avoid signed/unsigned comparisons.
783 * ports.h (scm_numptob): Change extern declaration to match.
784 (scm_current_load_port, scm_set_port_line_x,
785 scm_set_port_column_x): New prototypes.
787 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
788 test code, and it causes warnings.
790 * gh.h (gh_int2scmb, gh_uniform_vector_length,
791 gh_uniform_vector_ref): Added prototypes.
793 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
794 debugging support unconditionally. That's backtrace.c, stack.c,
795 debug.c, and srcprop.c.
796 (EXTRA_libguile_la_SOURCES): Omit those from here.
797 * Makefile.in: Regenerated.
799 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
801 * options.c (scm_options): Bugfix: Allow empty list of options!
803 * debug.c, debug.h (scm_single_step): Removed.
804 (scm_with_traps): New procedure. This procedure could easily be
805 written in Scheme but needs to be highly optimized.
807 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
809 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
810 Check SCM_TRAPS_P before trapping.
812 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
814 Changes to avoid signed/unsigned comparison warnings.
815 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
816 (scm_gc_sweep): Make n and j local to the blocks they're used in,
817 so they can have appropriate types for each application. Make i
818 signed. Use initializers in some spots. I'll probably pay for
820 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
821 (scm_must_realloc): Make nm unsigned.
822 (init_heap_seg): Make new_seg_index and n_new_objects signed.
823 (scm_init_storage): Use prototype-style definition, and make the
825 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
826 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
828 * filesys.c (scm_readlink): Make local vars rv and size ints, to
829 avoid signed/unsigned comparison warnings, and because the return
830 value of readlink may be -1. Don't bother casting the third
831 argument to readlink.
833 * filesys.c (scm_dirname, scm_basename): Move these to their own
834 page, at the end of the file.
835 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
837 * eval.h (scm_eval_options_interface): Add external prototype for this.
838 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
840 * eval.c (scm_lookupcar1): Make this static.
842 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
843 Make these prototype declarations, not K&R-style.
845 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
846 unsigned comparison warning.
848 * appinit.c: File removed. It had a single function in it, empty,
849 whose reason for existence is explained in no documentation or
850 comment. I think it's there as a default for some Tcl-style
851 initialization, but Tcl abandoned that approach a while ago.
852 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
853 (BUILT_SOURCES): Remove appinit.x.
854 * Makefile.in: Regenerated.
856 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
858 * Makefile.in: Regenerated using the last public version of
859 automake, not the hacked Cygnus version.
861 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
863 Remove Totoro kludge.
864 * Makefile.in, scmconfig.h.in: Regenerated.
865 * init.c, readline.c: Don't check if TOTORO is #defined.
867 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
869 * Makefile.am: Adjust for new thread configuration system.
870 (INCLUDES): Include the value of THREAD_CPPFLAGS.
871 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
873 (THREAD_LIBS): Definition deleted; automake will generate such
874 things automatically.
875 * Makefile.in: Regenerated.
877 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
879 Simplify smob and port marking; set the mark bit in the generic
880 marking code, and make marker routines only responsible for
881 turning up outgoing pointers.
882 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
883 before calling the marking function. Don't call the marking
884 function if it's zero.
885 * markers.c (scm_mark0): Just return #f. This function isn't
886 necessary at all now, but it's harmless to call it. We'll leave
887 it in so other folks' code doesn't croak at link time.
888 (scm_markcdr): Don't call SCM_SETGC8MARK.
889 * async.c (mark_async): Don't call SCM_SETGC8MARK.
890 * dynl.c (mark_dynl_obj): Same.
891 * root.c (mark_root): Same.
892 * srcprop.c (marksrcprops): Same.
893 * unif.c (markra): Same.
894 * variable.c (scm_markvar): Same.
895 * ports.c (scm_markstream): Same.
896 (void_port_ptob): Specify zero for our marking function.
897 * debug.c (debugobjsmob): Same.
898 * dynwind.c (guardsmob): Same.
899 * filesys.c (dir_smob): Same.
900 * fluids.c (fluid_smob): Same.
901 * fports.c (scm_fptob, scm_pipob): Same.
902 * mallocs.c (mallocsmob): Same.
903 * regex-posix.c (regex_t_smob): Same.
904 * smob.c (freecell, flob, bigob): Same.
905 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
906 * throw.c (jbsmob, lazy_catch_funs): Same.
908 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
910 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
911 scm_copy_tree on code in order not to let memoized code to leak
912 out. Thus, scm_copy_tree needs to copy vectors as well since
913 quasiquote can introduce evaluated code also inside vector
916 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
918 * eval.c (scm_copy_tree): Removed ability to copy vectors.
920 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
921 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
924 * unif.c: Say that ivect and uvect are of type signed and unsigned
925 long instead of int in commentary so that it correctly describes
928 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
930 * stime.c: Removed declaration of strptime. (It should be
931 declared by the system headers. If it turns out that some systems
932 don't, we'll handle that then.) (Thanks to Greg Troxel.)
934 * stime.h: Renamed TIMEH --> STIMEH
936 * backtrace.c (scm_display_error, scm_display_backtrace): In order
937 to increase portability, don't use structure assignment.
938 (Thanks to Nicolas Neuss.)
940 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
942 (finalize_fd_sets): Added empty statement after last case label.
943 (Thanks to Nicolas Neuss.)
945 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
948 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
950 * init.c, readline.c: OK, I won't have these readline.x bug
951 reports anymore. We've had them since April. The current reason
952 is a completely unintelligible failure of totoro.red-bean.com to
953 do the test for rl_getc_function in libreadline correctly. This
954 kludge overrides the test if we're on totoro so that the snapshot
955 generation process can work.
957 * readline.c: Define a strdup replacement if not existent on system.
959 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
961 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
962 This change makes scm_make_vector R5RS compatible. We cannot keep
963 the third argument since people want to be able to deduce the form
964 of the C function call only by looking at R5RS. (At the same time
965 we have removed some unnecessary complexity!)
967 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
968 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
969 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
970 argument in call to scm_make_vector.
972 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
974 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
975 This macro is useful in applications.
977 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
979 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
980 (scm_parse_path, scm_search_path): New Scheme level procedures.
982 * load.h (scm_internal_parse_path, scm_parse_path,
983 scm_search_path): Declared.
985 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
987 * filesys.c (dirname, basename): New procedures.
989 * init.c (scm_boot_guile_1): Removed condition around
992 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
993 new data type (guards) for representation of C level guards and
994 data on the wind chain.
995 (scm_internal_dynamic_wind): New function.
997 * dynwind.h: Declare scm_internal_dynamic_wind.
999 * root.h (scm_root_state): Added scm_cur_loadp.
1001 * root.c (mark_root): Added comment about cur_loadp.
1003 * load.c: #include "dynwind.h";
1004 (scm_primitive_load): Use scm_inner_dynamic_wind to update
1007 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
1009 * ports.c (current-load-port): New procedure.
1011 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1013 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
1014 not a tty, return #f.
1016 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
1017 to Julian Satchell and Roland Kaufmann.)
1019 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
1020 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
1022 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1024 * debug.h, debug.c (scm_start_stack): New function. Implements
1025 the guts of old scm_m_start_stack.
1027 * debug.c (scm_m_start_stack): Use scm_start_stack.
1029 * init.c (scm_start_stack, scm_restart_stack): Renamed to
1030 start_stack and restart_stack. (These have static scope.)
1032 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1034 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
1035 readline functions to come in release 2.3. (Thanks to Chet
1037 (handle_errors): Use the above functions.
1039 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1041 * readline.c: Improvements for readline support: Handle errors
1042 better; Implement before-read-hook.
1044 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1046 * init.c (scm_boot_guile_1), readline.c: Test for
1047 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
1048 assure that we have version >= 2.1.)
1050 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
1052 * readline.c (scm_readline): Defer interrupts while we're calling
1055 * readline.c (scm_add_history): Bugfix: Do strdup before giving
1056 away the string to add_history.
1057 (completion_function): Do completion for readline. (Thanks to
1059 (scm_filename_completion_function): New procedure: Filename
1061 (current_input_getc): New function. Use this one instead of
1062 standard getc from readline.
1064 * throw.c, throw.h (scm_handle_by_throw): New function: This
1065 handler throws errors to next handler on the dynwind chain.
1067 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
1069 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
1072 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1074 * procprop.c (scm_i_procedure_arity): New function. Returns arity
1076 (scm_procedure_properties): Modified to return arity together with
1078 (scm_procedure_property): Added the read-only property `arity'.
1079 (scm_set_procedure_property_x): It is an error to set the `arity'
1082 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
1083 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
1085 * procprop.h (scm_sym_arity): New symbol.
1087 * objects.c (scm_set_object_procedure_x): New procedure: Use this
1088 to set the dispatch procedure of an operator or entity object.
1090 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
1091 Made procedure slots read-only.
1093 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
1094 scm_tcs_cons_gloc case in zero args switch; Fixed args
1095 construction for operators in scm_tcs_cons_gloc case in two args
1098 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1100 * fluids.c: Removed use of assert.h (in order to avoid
1103 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
1105 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
1107 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
1108 change makes the evaluator safer at the cost of evaluation speed.
1109 It handles the case when the user has added a non-immediate
1110 improper end of the application form, e.g., `(+ 0 . x)'.
1111 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
1112 minimize the extra cost as much as possible. The new code is
1113 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
1114 problem with structs planted directly in the code (e.g. by a
1115 macro). This no longer causes segmentation fault. (Thanks to
1118 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
1119 arg `proc' in order to be able to throw errors; New argument
1122 * Removed extra #include "debug.h"
1124 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
1126 * scmsigs.c: Declare usleep as returning void on some systems.
1127 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
1130 * coop.c (usleep): Return void on some systems.
1132 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1134 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
1136 * coop.c: Changed return type of usleep to int.
1138 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
1139 isn't found in the OS.
1141 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
1142 isn't enabled. (Thought that I had made this change ages ago...)
1144 * iselect.c: Declare bzero if not defined by OS.
1146 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1148 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
1149 condition. (Thanks to John Tobey.)
1151 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
1152 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
1155 * __scm.h: Start the long-term project of moving to POSIX threads.
1156 Phase 1: Classification of all critical sections.
1157 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
1158 for A sections. (See comments in __scm.h for details.)
1160 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
1161 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
1163 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1165 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
1166 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
1167 (libpath.h, versiondat.h): Replaced dependency on Makefile with
1168 dependencies on $(srcdir)/Makefile.in
1169 $(top_builddir)/config.status in order to avoid circularity.
1171 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
1172 from argc if argc was 0 initially.
1174 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
1175 in generation of libpath.h.
1177 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
1179 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
1180 libguile from 2 to 3.
1182 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
1184 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
1186 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
1188 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
1189 scm_set_port_column_x, scm_port_filename,
1190 scm_set_port_filename_x): Removed optional arguments. Added
1191 proper argument checking.
1193 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
1194 stack size in machine words.
1196 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
1197 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
1198 to Ole Myren Röhne.)
1200 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
1202 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
1203 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
1205 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
1208 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
1209 procedure apply: Copy argument lists before pushing them unto the
1210 environment so that the environment won't get mutated due to
1211 manipulation of procedure arguments. This should perhaps be
1212 regarded as a temporary solution until someone finds a more
1213 efficient one. (Thanks to Maciej Stachowiak.)
1215 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
1217 * script.c (scm_compile_shell_switches): Use "guile" as default
1218 zero arg if argc is NULL.
1220 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
1222 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
1223 is zero. (Thanks to Dirk Herrmann.)
1225 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
1227 * ports.c (scm_add_to_port_table): First line is now line 0
1228 (was 1). (Interface changed according to suggestion by Per
1231 * backtrace.c (display_header): Add 1 to line and column numbers
1232 when presenting them to the user.
1234 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
1235 from debug.c --> eval.c
1237 * eval.h, eval.c (scm_eval_options_interface): New options
1239 (SCM_EVAL_STACK): New option: Size of newly created stacks,
1240 i.e. stacks for new threads.
1242 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
1244 * eval.c (unsafe_setjmp): Removed with #if 0.
1246 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
1249 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
1250 to avoid compiler warnings.
1252 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
1254 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
1256 * throw.c (handler_message): Print message on current error port
1257 instead of default error port. (Thanks to Maciej Stachowiak.)
1259 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
1261 * ports.c (scm_add_to_port_table): allocate in units of
1262 struct scm_port_table *, not struct scm_port_table.
1263 * posix.c (scm_close_pipe): remove the port from the port table
1265 Thanks to Rob Engle for both fixes.
1267 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1269 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
1270 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
1272 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1274 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
1276 * backtrace.c (display_error_body, display_backtrace_body),
1277 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
1278 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
1279 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
1280 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
1283 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
1284 don't receive the jmpbuf arg anylonger.
1285 (scm_catch): Don't accept a #f tag.
1286 (scm_throw): Check that key is a symbol.
1287 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
1289 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
1291 * async.c (async_pending): Removed declaration.
1293 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1295 * dynwind.c (scm_wind_chain): New debug function.
1297 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
1298 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
1299 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
1300 extra layer of functions around the body and handler of a thread.
1301 This extra layer makes sure that the handler is called in the
1302 dynamic context of the surround (= empty dynwind list), but under
1303 the *dynamic root* of the body. We can not use the dynamic root
1304 of the surround since that root belongs to another thread => stack
1305 is not handled correctly. It may seem ugly to use this extra
1306 layer, but the extra cost in terms of execution time is really
1307 negligible compared to the total amount of time required to create
1308 a thread, and it would reduce maintainability to duplicate the
1309 crucial and complicated steps performed by cwdr.
1311 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
1312 (SCM_ALLOW_INTS): Added thread switching code before interrupts
1313 get re-enabled. The important effect of this is that interrupts
1314 are blocked during thread switching so that thread data structures
1315 don't risk getting messed up by an unfortunate signal.
1316 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
1317 seems to do more aggressive optimization which actually move
1318 instructions around in these macros in a fatal way. Therefore:
1319 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
1320 just superstitious...)
1321 (SCM_TICK): Maybe do a context switch and take care of asyncs.
1322 This macro should be used instead of SCM_ASYNC_TICK since the
1323 latter doesn't do context switches any more.
1325 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
1326 instead of SCM_ASYNC_TICK.
1328 * coop.c, iselect.c: Since thread switches are now performed with
1329 interrupts masked, we can't use the old mechanism of delivering
1330 signals immediately when they arrive. Signals must instead be
1331 delivered when the asyncs run *after* the end of the critical
1332 section in scm_internal_select. But this also means after context
1333 switch so that the signal will be delivered to a different thread.
1334 To avoid this, I have changed the protocol of
1335 coop_wait_for_runnable_thread and friends so that they are allowed
1336 to return the original thread. So, if a signal arrives during
1337 scm_internal_select, we won't any longer be forced do a context
1338 switch, but can remain in the same thread and deliver the signal
1341 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
1342 scm_asyncs_pending and made it global.
1344 * iselect.c: Small fixes.
1346 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
1347 coop_condition_variable_init, coop_condition_variable_wait,
1348 coop_condition_variable_signal): Changed return type from `void'
1349 to `int'. This is to adhere closer to the pthreads interface.
1350 This, in turn, is part of an attempt to provide C versions of the
1351 mutex and condition variable primitives which can be part of a
1352 frontend to COOP or pthreads.
1354 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
1355 coop_condition_variable_destroy): New functions.
1357 * coop-threads.c (scm_wait_condition_variable): Use
1358 coop_condition_variable_wait_mutex.
1360 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
1361 Definitions moved to coop-defs.h.
1363 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
1364 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
1365 scm_cond_destroy): New C interface to mutecis and cond vars.
1367 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1369 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
1371 * iselect.c: Now several threads can wait on the same file
1372 descriptor. The behaviour is compatible with OS select: All
1373 threads waiting for the fd return with the same status.
1375 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1377 * coop-threads.c, threads.h (scm_spawn_thread): New function.
1378 Can spawn a thread from application C code.
1380 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1382 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
1383 gh_doubles2scm): New functions.
1385 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
1387 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
1388 commented-out version of gh_eval_str()
1390 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
1392 * socket.c (scm_bind): free soka after use.
1394 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
1396 * stime.c (tzvar): new variable.
1397 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
1398 avoid memory leaks when allocating.
1400 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
1402 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
1405 * gc.c, tags.h: Doc fixes.
1407 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1409 * eval.c (macro-eval!): Removed. This function was a design bug.
1410 It allowed memoized code to leak out to the scheme level. Most
1411 things that you could do with `macro-eval!' can be done with
1414 1997-12-20 Tim Pierce <twp@skepsis.com>
1416 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
1417 scm_fgets now depends on ftell(3) to know how many bytes were
1420 1997-12-15 Tim Pierce <twp@skepsis.com>
1422 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
1423 dealing with strings.
1425 1997-12-13 Tim Pierce <twp@skepsis.com>
1427 Make %read-line more suitable for implementing read-line efficiently.
1428 * ioext.c (scm_read_line): Strip the terminating newline from a
1429 string, and return a cons of the string and its terminator.
1431 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
1432 of the string that is read is stored in this memory location.
1433 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
1434 * genio.c, genio.h (scm_do_read_line): Update caller.
1435 * ports.h (scm_ptobfuns): Update typedef.
1436 * fports.c (scm_fptob, scm_pipob): Update struct.
1438 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1440 * filesys.c (set_element): Return file descriptor.
1441 (fill_select_type): Return the highest file descriptor.
1442 (scm_select): Tell select about the highest file descriptor. On
1443 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
1444 Therefore the extra overhead for calculating the maximum fd seems
1445 to be more than compensated. Is this correct? In any case,
1446 scm_internal_select will be much faster with this info.
1447 (scm_select, fill_select_type, set_element): Don't accept any kind
1448 of object in the file descriptor list or vector.
1450 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1452 * iselect.c (finalize_fd_sets): Bugfix.
1454 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1456 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1457 when using scm_internal_select (since we might switch to another
1460 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1462 * simpos.c (scm_system): always define: use sysmissing if not
1463 available. Check for HAVE_SYSTEM instead of _Windows (does
1464 Windows lack system or does it have an unusable one?).
1465 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1466 Let the argument be optional: if not supplied, call system(NULL).
1468 * ports.c (scm_close_port): relax the type check from OPPORTP to
1469 PORTP; closing a closed port is allowed.
1471 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1473 * fports.c (scm_fgets): Return if the last char in a chunk is
1474 newline. When fgets returns a string whose length is `size-1', it
1475 is ambiguous whether a whole line was retrieved, so we must check
1476 explicitly whether a line terminator is present.
1478 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1480 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
1481 before taking the CDR. (Thanks to Harald Meland.)
1483 * filesys.c (scm_stat): Slightly optimized.
1485 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
1487 * ports.c (scm_close_port): Make sure the port is open before
1490 * guile-snarf.in: Pass args through to gcc in a way that preserves
1491 whitespace boundaries. (Thanks to Greg Badros.)
1493 1997-12-02 Tim Pierce <twp@skepsis.com>
1495 * stacks.c (scm_frame_procedure): Reverse the logic in the return
1496 statement. (Thanks to Doug Evans for pointing this out.)
1498 1997-12-01 Tim Pierce <twp@skepsis.com>
1500 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
1502 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
1504 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
1505 errno macro expansion of this field name. (errno is a C
1506 preprocessor macro on some systems.)
1508 1997-11-29 Tim Pierce <twp@skepsis.com>
1510 * iselect.c: Doc fix.
1512 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
1514 * init.c (scm_start_stack): Removed initialization of
1515 scm_the_last_stack_var.
1517 * backtrace.h: Declare scm_the_last_stack_var.
1519 * backtrace.c: Define scm_the_last_stack_var.
1521 * root.c (mark_root): Don't mark the_last_stack_var.
1523 * root.h (scm_root_state): Removed the_last_stack_var.
1525 * throw.c: Added #include "fluids.h"
1526 (ss_handler): `the-last-stack' is now a fluid.
1528 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
1529 --> the_last_stack_fluid.
1531 * backtrace.c: Added #include "fluids.h"
1532 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
1533 (scm_backtrace): `the-last-stack' is now a fluid.
1535 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
1536 after scm_init_fluids.
1538 1997-11-28 Tim Pierce <twp@skepsis.com>
1540 * iselect.c: #ifdef USE_THREADS around thread-related includes.

1545 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1547 * iselect.c (coop_next_runnable_thread,
1548 coop_wait_for_runnable_thread): Disable interrupts so that no
1549 async is executed before a potential error_revive.
1550 (scm_internal_select): Disable interrupts during the parts of the
1551 code which manipulate the sleep queue and the file descriptors.
1553 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1555 * Makefile.am: Added iselect.c and iselect.h.
1557 * coop.c (coop_qinit): Initialize fields used by
1558 scm_internal_select.
1559 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1560 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1561 replacement in iselect.c.
1562 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1563 coop_join): If GUILE_ISELECT enabled, use
1564 coop_wait_for_runnable_thread instead of
1565 coop_next_runnable_thread.
1566 (usleep, sleep): New replacements for system functions if
1567 GUILE_ISELECT is enabled.
1569 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1571 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1573 * filesys.c: Added #include "iselect.h". Moved FD-macros to
1574 iselect.h. Implement Scheme level `select' using
1575 scm_internal_select. (See NEWS.)
1577 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1579 * init.c: Call scm_init_iselect.
1581 * iselect.h, iselect.c: New files. Implements

1584 1997-11-27 Tim Pierce <twp@skepsis.com>
1586 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1587 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1588 and scm_must_free, since ultimately the string returned will be copied
1589 by scm_makfrom0str anyway. Also, read any characters that may have
1590 been pushed onto the port with scm_ungetc.
1591 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1592 * ioext.c (scm_read_line): Free string after Guilifying it.

1604 gh_repl (argc, argv).
1606 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1608 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1609 and to invoke scm_shell().
1610 (gh_launch_pad): took out the loading of boot-9.scm from here,
1611 since it is probably best to let the user control that. In fact,
1612 gh_repl() now invokes scm_shell() which does that.
1614 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1616 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
1619 1997-11-22 Tim Pierce <twp@twp.tezcat.com>

1633 (gh_uniform_vector_ref): started implementing the uniform types in
1636 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
1638 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1639 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1641 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1643 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1644 configure.in was changed).
1646 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
1648 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1649 * Makefile.in: Regenerated.
1651 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1653 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1654 OPORT is an `open' port, not an output port.
1656 * filesys.c (scm_close, set_element, get_element, scm_chown,
1657 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
1658 SCM_COERCE_OUTPORT to cope with the printstate/port magic.

1661 scm_port_column, scm_set_port_column_x, scm_port_filename,
1662 scm_set_port_filename_x, scm_port_mode,
1663 scm_close_all_ports_except, scm_set_current_output_port,
1664 scm_set_current_error_port): Likewise
1665 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1666 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
1668 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
1669 * backtrace.c (display_backtrace_body): Likewise
1670 * fports (scm_setvbuf): Likewise
1671 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,

1678 Minor problems with substring-related tag changes.
1679 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1680 exactly what we want to leave in to detect substrings.
1681 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1682 * tags.h: Fix diagrams and comments describing the S tag bit;
1683 remove vestigial remarks about the D tag bit.
1684 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
1685 * strings.c: Formatting tweaks.
1687 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1688 variable first; then SCHEME_LOAD_PATH, with a warning message.
1689 (scm_parse_path): New function.
1690 * script.c: Doc fixes.
1692 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1694 Readline support, from Daniel Risacher.
1695 * readline.c, readline.h: New files.
1696 * init.c: #include "readline.h".
1697 (scm_boot_guile_1): Call scm_init_readline, if we have it.
1698 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1699 * Makefile.in: Regenerated.
1700 * scmconfig.h.in: Regenerated, after change to ../configure.
1702 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1704 * gh.h: gh_vector_set -> gh_vector_set_x
1706 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1708 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1709 with the ! -> _x mapping when going from Scheme to C.
1711 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1713 * gh.h (gh_reverse):
1721 (gh_assoc): added these gh_ functions implemented as macros.
1723 * gh_predicates.c (gh_null_p):
1724 (gh_string_equal_p): added these two missing predicates.
1726 * gh_list.c (gh_append):
1731 (gh_set_cdr_x): added these routines as I go through and try to
1732 complete the picture R4RS functions that should be mirrored in the
1735 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1737 * tags.h (scm_tc7_substring): Changed the comment and code to
1738 conform with the changes below. Folks! We have suddenly two new
1739 free tc7 codes!!! Jummy, jummy!
1741 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
1743 * Makefile.in: Rebuilt.

1768 Don't include "mbstrings.h".
1769 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
1770 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
1772 Don't include "mbstrings.h".
1773 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
1774 (SCM_SYMBOL_SLOTS): Define as 4.

1776 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
1777 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
1778 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
1779 struct.c, threads.c, throw.c, unif.c, variable.c: Use new

1799 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1801 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1803 * gh_test_c.c (c_vector_test): some improvements on the vector
1806 * gh.h (gh_vector): this used to exist but do the wrong thing.
1807 Now it (almost) does the right thing, though it takes a list
1808 instead of the individual arguments. I need to see how it could
1810 (gh_list_to_vector): added this function as a macro. Corresponds
1811 to Scheme's (list->vector ...).
1812 (gh_vector_to_list): added this function as a macro. Corresponds
1813 to Scheme's (vector->list ...).
1815 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1816 gh_vector_ref, so that it resembles the Scheme routines more.
1817 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1818 resembles the Scheme routines more.
1819 (gh_make_vector): this used to be (stupidly) called gh_vector().
1820 This is the right name, since it does the same thing as the Scheme
1821 (make-vector ...) procedure.
1823 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1825 * ports.h: #include "libguile/print.h"

1828 Some indentation fixes.
1830 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
1831 longer a user field; New field: class_flags.

1838 gh_int2scmb(), which is now tagged as obsolete.
1840 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1842 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1843 macros should by convention not test for NIMPness.)
1844 (SCM_COERCE_OPORT): Adjust indentation.
1846 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1847 SCM_NIMP test before SCM_PRINT_STATE_P.
1849 * struct.c, struct.h, gc.c: Renamed:
1850 scm_struct_i_layout --> scm_vtable_index_layout

1854 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1856 * struct.c (scm_print_struct): Use new printer slot; Default
1857 printing: Also output hex code of vtable so that type identity
1858 will be indicated as well.
1859 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1860 Removed struct_printer_var; Removed struct-vtable-offset;
1861 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1862 vtable-offset-user): New constants.
1864 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.

1867 the type represented by this vtable.
1869 * print.c (scm_iprin1): Don't print arguments of macro
1870 transformers. (They are always: exp env.); Bugfix: Unmemoize
1871 transformer source with correct environment.
1873 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1875 Streamlining of call-with-dynamic-root:

1878 there is now only one catch.
1879 (cwdr_outer_body): Removed.
1880 (cwdr_handler): New function.
1881 (scm_internal_cwdr): New function to perform the function of cwdr
1882 but take args that are more useful to C code. Also, the handler
1883 is now invoked *outside* of the new dynamic root, like the docs
1884 say. We no longer have to catch absolutely all errors, the caller
1885 is responsible for using a handler that does not throw, if he
1887 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1888 * root.h (scm_internal_cwdr): New prototype.
1890 Even more but risky streamlining:
1892 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1893 allocation of the jumpbuf of a root continuation. The changes
1894 below are controlled by it. They are now deactivated.
1895 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1896 the JMPBUF of the scm_rootcont to NULL before returning.
1898 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1899 when they are non-NULL.
1900 (scm_gc_mark): Likewise, mark only when non-NULL.
1902 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1903 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1905 * gc.c (scm_done_malloc): New function.
1906 gc.h (scm_done_malloc): New prototype.
1908 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.

1915 a certain value is acceptable as a port argument.
1916 (scm_print_state_vtable): New variable.
1917 (scm_free_print_state): Set `revealed' field to false.
1918 (scm_iprin1): Call user supplied closure printer with
1919 scm_printer_apply. Print in the traditional way when there isn't
1920 one or when it returns #f.
1921 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1922 Accept a port/print-state pair in addition to just a port.
1923 (scm_prin1): Don't return the print_state to the pool when it has
1925 (scm_printer_apply): Set `revealed' field of print_state to true.
1926 (scm_init_print): Set scm_print_state_vtable.
1927 (print_state_fluid, print_state_fluid_num): Removed.
1929 * throw.h (scm_handle_by_proc_catching_all): New prototype
1930 throw.c (scm_handle_by_proc_catching_all): New function
1932 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1934 * Makefile.in: Regenerated with automake 1.2c.
1936 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1938 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1939 was looping endlessly.
1941 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1943 * strports.c (scm_eval_string): Don't close the port.
1945 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1946 former returns a nice normal integer. (Thanks to Daniel
1949 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1951 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1952 makefile variable as a build parameter called LIBS. The
1953 build-guile program will use this, for the time being.
1954 * Makefile.in: Regenerated.
1956 Thanks to Shiro Kawai:
1957 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1958 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1961 * Makefile.in: Regenerated with automake 1.2a.
1963 * script.c (scm_compile_shell_switches): If we hit the -c or --
1964 arguments, don't set the car of (command-line) to scm_usage_name,
1965 the prettified name of the guile executable; give it the full
1966 path, the way shells usually handle $0.
1968 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1970 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1971 Scheme-level name `array-map' and renamed `serial-array-map' to
1972 `serial-array-map!'.
1974 * backtrace.c: Introduced exception handlers which now enclose
1975 `display-error' and `display-backtrace' so that error reporting
1976 won't get into infinite loops if an error occurs during displaying
1977 of the error. This can very easily happen with user supplied
1978 print call-back routines.
1980 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1982 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1983 the names `serial-array-map' and `array-map' should be removed.)
1985 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1987 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1988 Added #include "objects.h"
1990 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1991 Add #include "feature.h".
1993 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1994 (modinclude_HEADERS): Added objects.h.
1996 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1997 This test is needed at many places in the code and should be
1998 abstracted. (Motivated by the need of this test in libguiletk.)
2000 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
2001 (scm_eval_string), load.c (scm_primitive_load,
2002 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
2003 Use SCM_EOF_OBJECT_P.
2005 * eval.c (scm_init_eval): Add feature `delay'.
2007 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2009 * scmhob.h: Removed.
2011 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2013 * list.h (SCM_LISTn): New macros. Make list creation in C code
2014 prettier. The idea comes from STk.
2016 * sequences.h, sequences.c, append.h, append.c: Removed. These
2017 files implemented non-R4RS operations which would encourage
2018 non-portable programming style and less easy-to-read code.
2020 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
2023 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
2024 sequences.h, #include append.h.
2026 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
2029 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
2031 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
2033 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
2035 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2037 * eval.c: Added #include "objects.h"
2039 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
2042 * smob.c (scm_smob_prehistory): Create two objectsmobs with
2043 adjacent smob numbers.
2045 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2047 * procprop.h: Added declaration of scm_i_inner_name.
2049 * gsubr.c: New global symbol scm_i_inner_name.
2051 * debug.c (scm_procedure_name): Try procedure property
2052 `inner-name' if `name' fails.
2054 * print.c (scm_iprin1): Use scm_macro_name.
2056 * eval.c (scm_m_define): Give names to macros as well; Only the
2057 first top-level definition gives a procedure/macro a name.
2058 Otherwise confusing names can turn up in backtraces.
2059 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
2060 `name'; Give names to macros as well.
2062 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
2063 (scm_macro_transformer): Use SCM_CLOSUREP instead of
2066 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2068 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
2070 (prinmacro): Removed. The code has been moved/merged into print.c
2071 in order to decrease code redundancy. We want macros to print in
2072 a way equivalent to procedures, and it would be silly to duplicate
2073 the required code. (We don't want to maintain two places.)
2074 (macrosmob): Print field is now a NULL pointer.
2076 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
2077 scm_macro_transformer): New prototypes.
2078 (scm_tc16_macro): Declared.
2080 * print.c (scm_iprin1): Added code for printing of macros. Macros
2081 are now printed in a way equivalent to procedures.
2083 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
2085 * procs.h (scm_closure_p): Added declaration.
2087 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2089 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
2090 Shouldn't pass "heap" as the subr name.
2092 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
2094 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
2095 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
2096 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
2097 gh_equal_p): Use SCM_NFALSEP, instead of testing against
2098 SCM_BOOL_T. Any non-false value is true.
2100 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2102 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
2103 scm_gensym): Added prototypes.
2105 * symbols.c (scm_gensym): New function. This will speed up
2106 certain types of applications (such as macro systems) which
2107 generate lots of symbols.
2109 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2111 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
2113 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
2115 * unif.c (scm_shap2ra): tighten the checking of the array dimension
2116 specifier, since (2) or (2 . 3) would cause SEGV.
2117 (scm_transpose_array): more argument checking fixes.
2119 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
2121 * Makefile.in: Regenerated.
2123 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
2125 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
2127 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2129 * error.c, error.h (scm_error_callback): Removed (see NEWS).
2131 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
2133 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
2134 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
2137 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
2138 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
2139 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
2140 scm_array_p, scm_array_rank, scm_array_dimensions,
2141 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
2142 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
2143 scm_array_prototype): Added case scm_tc7_wvect.
2145 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
2147 * errno.h: prototype for scm_strerror.
2148 * error.c (scm_strerror): new procedure.
2150 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2152 * list.c (scm_list_append_x): Allow non-pair as last argument.
2153 This is consistent with the R4RS append and is probably the
2154 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
2156 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2158 * stime.h: prototype for scm_times.
2159 * stime.c (scm_times): new procedure.
2160 * ioext.c (scm_fseek): if the first argument is a file descriptor
2162 (scm_ftell): if the first argument is a file descriptor call lseek
2164 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
2165 * filesys.c (scm_chmod): if the first argument is a file descriptor,
2167 (scm_chown): if the first argument is a port or file descriptor,
2169 (scm_truncate_file): new procedure.
2170 Add DEFER/ALLOW INTS to a few other procedures.
2171 (scm_fsync): new procedure.
2172 (scm_open_fdes): new procedure.
2173 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
2175 (scm_fcntl): the first argument can now be a file descriptor. The
2176 third argument is now optional.
2178 * posix.c (scm_execl, scm_execlp): make the filename argument
2179 compulsory, since omitting it causes SEGV.
2180 (scm_sync): return unspecified instead of #f.
2181 (scm_execle): new procedure.
2182 (environ_list_to_c): new procedure.
2183 (scm_environ): use environ_list_to_c. disable interrupts.
2184 (scm_convert_exec_args): take pos and subr arguments and
2185 improve error checking.
2187 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2189 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
2190 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
2191 argument to SCM_ASSERT. Furthermore, the name of the function
2192 should be passed as first argument when signalling
2193 SCM_WNA. (Thanks to Thomas Morgan)
2195 * gsubr.c (scm_gsubr_apply): From Radey Shouman
2196 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
2197 dispatches on the number of actual args has a default case
2198 reporting an internal error. This is a vestige from a version
2199 that mallocated a SCM vector to hold the arguments. In the
2200 current version this check is too late: if it ever happens we will
2201 have already overstepped the bounds of the array.
2203 Also, the patch [...] adds a check for too many actual arguments."
2205 mdj: Removed check for "internal programming error".
2207 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2209 * gh_io.c (gh_write): New function.
2211 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
2212 throw.c (scm_internal_stack_catch): New sibling to the other catch
2213 functions. Code moved from gh_eval.c.
2214 throw.h: Added header.
2215 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
2216 scm_internal_stack_catch.
2218 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2220 * ioext.h: fix up prototypes.
2221 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
2222 Scheme name is now dup->fdes.
2223 (scm_dup_to_fdes): make the second argument optional and
2224 fold in the functionality of scm_primitive_dup.
2225 (scm_primitive_dup): deleted.
2227 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
2229 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
2230 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
2231 ultrix are defined. Use setvbuf instead of setbuf.
2232 (scm_setvbuf): new procedure.
2233 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
2234 (scm_setfileno): moved from ioext.c.
2235 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
2236 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.

2246 state as nested data while they are printed.
2247 (print_state_fluid, print_state_fluid_num): New variables.
2248 (scm_init_print): Initialize them.
2249 (scm_iprin): If print_state_fluid carries a print_state, use that
2250 instead of creating a new one.
2251 (scm_printer_apply, apply_stub, struct apply_data): New
2252 definitions to help with calling printer functions written in
2254 * print.h (scm_printer_apply): New prototype.
2256 * struct.c (scm_print_struct): Use scm_printer_apply to call the
2257 user defined struct printer.

2267 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
2268 SCM_ASSERT: arg comes before pos.
2270 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2272 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
2273 to a list of length zero correctly.
2275 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2277 Supply an `fgets' method for port objects to do fast line i/o.

2291 * ioext.h: removed scm_duplicate_port prototype.
2293 * ioext.c (scm_primitive_dup2): return the new file descriptor
2294 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
2296 (scm_fdopen): bug fix: don't try to make port unbuffered until its
2297 stream has been set.
2298 (scm_duplicate_port): deleted, there's now an implementation in
2300 (scm_primitive_dup2): do nothing if newfd == oldfd.
2302 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
2304 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the

2308 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
2310 * fluids.c (next_fluid_num): don't do
2311 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
2313 * ports.h: prototypes too.
2314 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
2316 * fports.h: prototype too.
2317 * fports.c (scm_evict_ports): moved from ioext.c.
2319 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>

2344 (scm_make_root): Call scm_copy_fluids to make fluid bindings
2345 unique for the new root when it has a parent.
2347 * smob.h: Include "libguile/print.h" to make scm_print_state

2351 data. (dynl_smob): Use it.
2352 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
2353 the dynamic object data below the linking of the object to avoid
2354 memory leak when the linking code throws an error. Now the code
2355 leaks a whole dynamically linked library when must_malloc throws,
2356 but that should be much less likely.
2358 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
2360 Changes to compile under gnu-win32, from Marcus Daniels:
2361 * stime.c (tzset): If tzset isn't provided, make it a NOP.
2362 (scm_localtime): Change SCM_EOF to SCM_EOL.
2363 (scm_mktime): Likewise.
2364 * socket.c: Don't include sys/un.h unless autoconf tells
2365 us Unix domain sockets are available.
2366 (scm_fill_sockaddr): Ignore Unix domain code.
2367 (scm_addr_vector): Likewise.
2368 (scm_init_addr_buffer): Likewise.

2376 (scm_setpwent): For setpwent.
2377 (scm_setegid): For setegid.
2378 * net_db.c (scm_inet_netof): Don't include unless support

2393 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
2394 scm_misc_error, not SCM_EOF.
2396 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
2397 arguments for formatting the error message, not SCM_BOOL_F. I
2398 think this is left over from the (eq? '() #f) days.
2400 * read.c (recsexpr): Give this a dummy definition if
2401 DEBUG_EXTENSIONS isn't #defined.
2403 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
2405 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

2415 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
2416 alloca.lo will be included in @LIBLOBJS@. Something better than
2417 this should be possible.
2418 * Makefile.in: Regenerated.
2420 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2422 * simpos.h: prototype for scm_primitive_exit.
2423 * simpos.c (scm_primitive_exit): new procedure, terminates the
2424 process without unwinding the stack.
2426 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
2428 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
2429 argument and logior its components together, so the user doesn't
2430 have to do this explicitly. Also, if regexp/basic is supplied, then
2431 turn off REG_EXTENDED.
2432 (scm_init_regex_posix): New regexp/basic symbol.
2433 (REG_BASIC): #define this if it is not already present.
2435 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

2449 * Makefile.in: Regenerated.
2451 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
2452 flag; I don't think we support it.
2453 (scm_make_regexp): Make sure the user doesn't pass the
2456 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
2458 (scm_init_regex_posix): Define constants for the REG_mumble flags;
2459 name them according to the SCSH convention: regexp/mumble.

2466 Makefile directory variables. Print a message, but don't print
2468 (versiondat.h): Print a message, but don't print all the commands.
2469 * load.c: #include "alist.h".
2470 (init_build_info): New function.
2471 (scm_init_load): Call it.
2472 * Makefile.in: Regenerated.
2474 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
2476 * root.c: Establish a reliable catch-all handler for the new root.
2477 After all the Scheme handler function might signal an error too,
2478 and we don't want to lose that.
2479 (cwdr_inner_body): Renamed from cwdr_body.
2480 (cwdr_outer_body): New function, to establish the user's handler,
2481 and pass control to cwdr_inner_body.
2482 (cwdr): Establish the reliable catch-all handler here, and pass
2483 control to cwdr_outer_body.
2484 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
2485 the user's handler through to cwdr_outer_body.
2486 * throw.c (scm_handle_by_message): Move guts into....
2487 (handler_message): New static function.
2488 (scm_handle_by_message_noexit): New function.
2489 * throw.h (scm_handle_by_message_noexit): New prototype.
2491 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
2492 across this. Only works on GCC. Otherwise, we hope for the best.
2493 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2494 the feeling that real thread systems will not need this...
2496 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2498 Try to detect when people are using one version of libguile and a
2499 different version of ice-9. People have been skewing things and
2500 sending in bug reports.
2501 * Makefile.am (versiondat.h): New file to generate.
2502 * version.c: #include "versiondat.h", to get version info.
2503 (scm_libguile_config_stamp): New function.
2504 * script.c: #include "version.h".
2505 (scm_compile_switches): Call scm_version to get version number.
2506 * scmconfig.h.in, Makefile.in: Regenerated.
2507 * Makefile.in: Regenerated.
2509 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
2510 primitive definitions under their Scheme names.
2512 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2513 1:2. Helps avoid confusion between installed and uninstalled libs.
2515 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2518 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2519 backslash from definition; this should be used like: GDB_INTERFACE;
2521 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2523 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
2524 new port unbuffered until its stream has been set.
2526 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2528 * ports.h: new prototype.
2529 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
2531 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
2533 Make things compile neatly under Sun's C compiler.
2534 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
2535 * extchrs.c (xmbtowc): Make the second arg a normal char, not
2536 unsigned, because that's what the ANSI function takes.
2537 * extchrs.h (xmbtowc): Corresponding change to prototype.
2538 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2540 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2541 argument plain char *.
2542 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2544 * tag.c (scm_tag): Remove unreachable statement.
2545 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2546 top of the word, it should be unsigned.
2548 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2549 is defined, to avoid warnings; it's only used in the
2550 conflict-checking code. Which might go away anyway.
2551 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2552 conditionals; put the label definition in an #if too, to stifle
2555 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2556 ChangeLog-threads in the distribution.
2557 * Makefile.in: Regenerated.
2559 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2561 * guile-snarf.in: Changed regexp to support CPPs that insert
2562 whitespace between lexical tokens (which munges the `%%%' snarf
2565 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2567 * load.c (scm_init_load_path): Append $(datadir)/guile to
2568 %load-path, so modules do not have to be installed in Guile's
2569 current version directory.
2571 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2573 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2574 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2575 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2576 call the sysdep functions with deferred ints.
2577 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2578 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2579 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2582 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2585 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2587 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2589 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2591 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2594 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2596 * eval.c (scm_lookupcar1): New procedure to cope with a race
2597 condition during lookup (when using threads).
2598 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2599 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2602 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2604 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2605 supplied. (Change from Tim Pierce.)
2607 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2609 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2610 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2611 default and not `()'. `#f' is the canonical non-value in Scheme,
2614 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2616 * struct.c (struct_printer): New variable that holds a handle on
2617 the Scheme variable *struct-printer*. This variable can be set by
2618 Scheme code to override the printing of structures.
2619 (scm_print_struct): If struct_printer is set, call it. If it is
2620 not set, or returns #f, print the structure in the old fashion.
2621 Include "eval.h" for scm_apply.
2623 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2625 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2626 scm_struct_i_n_words to get the number of fields, not
2627 -scm_struct_n_extra_words.
2629 On the route to fancier struct printing:
2630 * struct.c (scm_print_struct): New function to print a structure.
2631 Include "genio.h" to support it. This function doesn't do
2632 anything interesting right now, but I think it should be here
2634 * struct.h: Include "print.h" and add prototype for
2636 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2637 print structures ourself.
2639 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2641 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2642 before applying the handler in case it doesn't return.
2644 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2646 * scmsigs.h, async.h: updated.
2648 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2651 * posix.c (scm_uname): interpret only negative values as an error.
2652 Solaris normally returns a positive value.
2654 * script.c (scm_compile_shell_switches): if we are not going into
2655 an interactive repl, set scm_mask_ints to zero so that asyncs can
2658 * simpos.c (scm_system): don't ignore/unignore signals around
2661 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2664 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2665 done in boot-9.scm instead.
2667 * scmsigs.c, async.c: Major rewriting of signal handling code.
2668 (scm_sigaction): new procedure.
2669 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2671 (scm_raise): return unspecified, throw error on failure.
2673 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2675 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2676 feature, to help boot-9.scm decide whether to import the regex
2679 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2681 * eval.c: Include scmconfig.h at the beginning of the file so that
2682 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2685 * regex-posix.c: #include "_scm.h" before conditionally #including
2686 <regex.h>; the former defines HAVE_REGCOMP.
2688 * regex-posix.c: #include <regex.h> conditionally, so the file is
2689 CPP'able (for dependency scanning) even on systems that don't have
2692 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2694 Add new R4RS-compliant syntax for keywords.
2695 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2696 regardless of the setting of the `keywords' read option.
2697 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2698 can be re-read no matter what the setting of the `keywords' read
2701 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2703 Add support for POSIX regular expressions.
2705 * regex-posix.c, regex-posix.h: New files. (Some code
2706 is taken liberally from rx/rgx.c in the old Guile dist.)
2708 * init.c: Include regex-posix.h.
2709 (scm_boot_guile_1): Call scm_init_regex_posix.
2711 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2712 Add regex-posix.[ch] sources.
2713 * Makefile.in: Regenerated.
2715 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2716 to do this automatically? It didn't for me, bleh.)
2718 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2720 * fports.c (print_pipe_port): New function.
2721 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2722 latter doesn't even take the right arguments.
2724 * Makefile.am: Increment shared lib revision number. I think
2725 sometimes the uninstalled Guile finds the installed shared lib;
2726 Gord says doing this might help. As things turned out, I can't
2727 say whether it does.
2728 * Makefile.in: Regenerated.
2730 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2731 passing it as the closure argument to scm_boot_guile. (Bill
2734 * ports.c (print_void_port, putc_void_port, puts_void_port,
2735 write_void_port, flush_void_port, getc_void_port, close_void_port,
2736 noop0): Use ANSI prototypes instead of K&R declarations, so the
2737 initialization of void_port_ptob gets aggressively type-checked.
2738 Fix arguments of print_void_port and write_void_port. (Bill

2772 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2774 * script.c (scm_find_executable): Use prototype-style definition
2775 here; apparently it's not quite right to have const in a prototype
2776 and then use a K&R declaration. I wonder if stuff like this will
2777 go away if we compile with -Wrequire-prototypes, or whatever that
2778 is... (Bernard URBAN)
2780 * scmhob.h: New text from Bernard URBAN.
2782 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2784 * script.c: Don't #define const on hpux. Configure takes care of
2785 this. (Thanks to Larry Schwimmer.)
2787 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2788 decide whether to #include <unistd.h>, instead of listing a bunch
2789 of systems. Don't #include stdio twice. Removed dyked-out
2790 definition of scm_find_impl_file.
2792 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2794 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2795 library version info to 1:0.
2796 * Makefile.in: Regenerated.
2798 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

2802 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2803 throw.c: Update copyright years; these files have been worked on
2804 significantly in 1997, but only had copyright years for 1996.
2805 Also, change name of copyright holder on some from Mikael
2806 Djurfeldt to Free Software Foundation; he has signed papers
2807 assigning the changes to the FSF.
2809 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2810 reason not to give the user the option.
2812 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2813 Return #f on end-of-file when scanning table (i.e. when called
2814 with no arguments). Try to catch errors, when we can.
2815 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2817 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2818 external declarations. These are useful.
2820 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2822 * posix.c: don't include <sys/select.h> or define macros for
2823 select, since they were not used in this file.
2825 * filesys.c (scm_select): make the fifth parameter microseconds,
2826 not milliseconds. let the fourth parameter be either a real value
2827 or an integer or #f. The first, second and third arguments can
2828 now be vectors: the type of the corresponding return set will be
2830 (set_element, get_element): new static procedures.
2832 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2834 * strports.c (scm_eval_string): New function.
2835 (scm_eval_0str): Trivially re-implemented in terms of
2837 * strports.h (scm_eval_string): New extern decl.
2839 * net_db.c (h_errno): Add extern decl for this.
2841 * fports.c (local_pclose): New function.
2842 (scm_pipob): Use it in the initializer here.
2845 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2846 Use a meaningful error message when signalling an error. For
2847 this, scm_gethost must check h_errno rather than errno.
2849 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2851 * Makefile.in: Regenerated, using automake-1.1p.
2853 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2855 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2856 not SCM_UNSPECIFIED.
2858 * script.c (scm_compile_shell_switches): don't append (quit) if
2860 (scm_shell): call scm_exit_status and exit on the result of the
2863 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2865 Ensure that shared substrings are handled properly when passed to
2866 a system call or other foreign function. Many thanks to Tim
2868 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2869 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2870 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2871 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

2883 SCM_COERCE_SUBSTR to make sure shared substrings are
2886 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2888 * error.c (scm_error): Add newline to error message.
2890 * init.c (scm_init_standard_ports): Doc fix.
2892 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2894 * dynl-shl.c: Completely replaced with new code from Bernard
2897 * script.c (scm_ice_9_already_loaded): New variable.
2898 (scm_compile_shell_switches): Use it.
2900 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2902 * filesys.c (scm_input_waiting_p): add missing third argument to
2905 * stime.c (scm_localtime): copy the result of localtime before
2906 calling gmtime in case they share a buffer.
2907 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2910 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2912 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2914 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2916 * Makefile.am (check-local): New target, which causes 'make check'
2917 to run gh_test_c and gh_test_repl, with some trivial input.
2918 * Makefile.in: Rgnrtd.
2920 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2922 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2925 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2927 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2928 sure how this was supposed to work.
2929 (scm_async_click): don't send SCM_TICK_SIGNAL.
2930 (scm_init_async): don't initialize %tick-thunk.
2932 * the following change doesn't affect the Scheme interface:
2933 gc-thunk is called at the end of garbage collection. however it's
2934 no longer implemented by pretending it's a signal.
2936 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2937 system async corresponding to scm_gc_thunk.
2938 * async.h: declare scm_gc_async.
2939 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2940 gc-thunk directly, instead of going through a signal handler.
2941 (scm_gc_async): new variable, points to the GC system-async.
2942 (scm_init_async): save the GC async as scm_gc_async instead
2943 of using system_signal_asyncs.
2944 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2946 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2948 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2949 Don't screw up if we're interrupted.
2950 * Makefile.in: Regeneradet.
2952 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2954 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2956 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2957 we're not using AM_INIT_GUILE_MODULE any more.
2958 * Makefile.in: Reneregated.
2960 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2962 Functions for finding variable bindings, grace à Tim Pierce.
2963 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2964 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2966 Get 'make dist' to work again.
2967 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2968 * Makefile.in: Regenerated, like a surry without a fringe on top.
2970 Changes for reduced Guile distribution: one configure script,
2972 * configure.in, configure: Removed.
2973 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2974 real configure script lives.
2975 * Makefile.in, scmconfig.h.in: Regenerated.
2977 * init.c: #include "script.h", to get prototype for script.c's
2980 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2982 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2983 scm_must_malloc, not raw malloc.
2985 * script.c (scm_compile_shell_switches): Dyke out debugging output
2988 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2990 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2992 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2993 system has them. Hope this is safe. Previously
2994 sys/timeb.h was included if HAVE_FTIME was defined or if
2995 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2996 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2998 * ioext.c (scm_setfileno): add missing third argument to
2999 scm_misc_error call.
3001 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
3003 * eq.c (scm_equal_p): Correctly compare strings of different
3004 varieties. (Thanks to Tim Pierce.)
3006 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
3008 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
3009 #! block comment must occur on a line all by itself.
3011 Move most of the guts of shell command processing into libguile,
3012 so guile.c can be very small (and eventuallly auto-generated. (I
3013 mean, generated mechanically, not self-generated. Hmm.))
3014 * guile.c, script.c, script.h: New source files.
3015 * init.c (scm_boot_guile_1): Call scm_init_script.
3016 * libguile.h: #include "script.h".
3017 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
3018 targets, for new executable.
3019 (libguile_la_SOURCES): Mention script.c.
3020 (modinclude_HEADERS): Add script.h.
3021 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
3022 not dynamic linking is enabled. This is because we're generating
3023 executables now. Move CY_AC_WITH_THREADS call after those, so the
3024 values of cy_cv_threads_libs captures the libs chosen above.
3025 * Makefile.in, configure, aclocal.m4: Regenerated.
3027 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
3028 We don't maintain this interface any more, and it just confuses
3031 * alloca.c: #include <scmconfig.h>, not <config.h>.
3032 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
3033 it'll get included in disties.
3035 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
3037 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
3038 be distributed, because they confuse people.
3039 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
3041 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
3043 * configure.in: check for presence of gethostent (not present on
3044 OpenBSD by default).
3045 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
3046 * configure, scmconfig.h.in: Regenerated.
3048 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
3050 * backtrace.c (scm_backtrace): Split message string across
3051 newlines properly. GCC is more tolerant of this than other

3056 Merge threads directory into libguile.
3057 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
3058 threads.h: New source files.

3060 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
3062 (modinclude_HEADERS): Add threads.h, coop-defs.h.
3063 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
3064 coop-threads.c.cygnus, coop-threads.h.cygnus.
3065 * configure.in: If we're using threads, include threads.o in
3067 * _scm.h, libguile.h: threads.h lives in this directory now.
3068 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
3069 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
3070 currently used, but brought along for information's sake.
3071 * ChangeLog-threads: log from old 'threads' directory.
3072 * Makefile.in, configure: Rebuilt.
3074 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
3076 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
3079 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
3081 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
3083 Merge GH interface library into libguile.
3084 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
3085 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
3086 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
3087 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
3089 (EXTRA_libguile_la_SOURCES): ... here.
3090 (pkginclude_HEADERS): Add variable, to get gh.h installed.
3091 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
3092 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
3093 New variables, describing how to build the gh test programs.
3094 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
3095 build the test programs, and we probably should have been linking
3096 libguile.la against them all along, to support AIX shared libs.
3097 Add cflags for threads to CFLAGS; add libs for threads to new
3098 variable THREAD_LIBS, used in Makefile.am.
3099 * ChangeLog-gh: log from old `gh' subdirectory.
3100 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
3102 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
3104 * acconfig.h: Undo change of Apr 9; including the definition of
3105 PACKAGE in the guile headers conflicts with applications' own
3107 * scmconfig.h.in: Regenerated.
3109 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

3116 when PROC is receiving no arguments.
3118 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
3120 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
3121 have S_IFSOCK. This is the case under Ultrix.
3123 * posix.c (scm_status_exit_val, scm_status_exit_val,
3124 scm_status_term_sig, scm_status_stop_sig): Modified to work with
3125 Ultrix versions of WIFSTOPPED, etc., which assume that their
3126 arguments are lvalues (hmm).
3128 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
3130 * eval.c: Doc fixes.
3132 * throw.c: Doc fixes; rearranged.
3134 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
3136 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
3138 * acconfig.h: Added entry for PACKAGE.
3139 * scmconfig.h.in: Regenerated.
3141 Changes to work with automake-1.1n, which has better libtool support.
3142 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
3143 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
3145 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
3147 * Makefile.in: Rebuild.
3149 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3151 * stime.c (scm_mktime): take an optional zone argument.
3152 (scm_localtime): check putenv return value.
3153 (scm_strftime, scm_strptime): moved from posix.c. move #include
3155 stime.h, posix.h: update prototypes.
3156 (bdtime2c, setzone, restorezone): new static procedures.
3157 (scm_mktime, scm_strftime): use them.
3158 (scm_strftime): don't call mktime before strftime. Use
3159 filltime for return value.
3160 (filltime): convert NULL zname to #f.
3161 (scm_strptime): return a count of characters consumed, not
3162 the remaining string.
3164 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3166 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
3167 (scm_mktime): likewise.
3169 Uncomment localtime and mktime.
3171 * configure.in: add AC_STRUCT_TIMEZONE.
3173 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3175 * stime.c (scm_init_stime): don't define ticks/sec.
3176 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
3177 return value problem and is still portable.)
3179 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3181 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
3182 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
3183 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
3184 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
3185 cpp_err_symbols.c): Corresponding changes.
3186 * Makefile.in: Regenerated.
3188 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3190 * posix.c (scm_putenv): don't check HAVE_PUTENV.
3191 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
3192 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
3193 * putenv.c: new file, from sh-utils 1.12.
3195 * posix.c (scm_environ): use malloc in place of scm_must_malloc
3196 since allocation isn't for Scheme objects.
3197 (scm_putenv): copy strings before placing in the environment.
3199 * stime.c (scm_current_time): throw an error if time returns -1,
3200 instead of returning #f.
3201 (scm_get_internal_real_time, scm_get_internal_real_time): use
3202 scm_long2num for return value instead of SCM_MAKINUM.
3204 * stime.h: prototypes updated.
3206 * stime.c (scm_time_in_msec): apparently unused, deleted.
3208 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
3210 * configure.in: check for gettimeofday.
3212 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
3213 which may be more usefully portable than a gettimeofday interface.
3215 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
3217 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
3219 * Makefile.in: Regenerated.
3221 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3223 * stime.c (filltime): recovered static procedure.
3224 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
3227 * posix.h: add prototype for scm_close_pipe, remove prototypes for
3228 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
3230 * posix.c (scm_mknod): split the mode argument into type and perms
3231 arguments, like the extra fields returned by stat.
3233 * fports.c (scm_pipob): set the close, free and print procedures.
3234 (scm_close_pipe): new procedure.
3236 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
3237 define them in boot-9.scm
3239 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3241 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
3242 wan't defined. Don't include fd.h.
3244 * Previously fd.h was regenerated whenever configure was run,
3245 forcing a couple of files to be recompiled.
3247 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
3248 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
3249 Check for _fileno as well as _file.
3251 * ioext.c: don't fd.h.
3252 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
3255 * Change the stratigy for getting information about errno
3256 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
3257 generating lists of symbols during the build process, which will
3258 not always work, include comprehensive lists in the distribution.
3259 To help keep the lists up to date, the "check_signals" and
3260 "check_errnos" make targets can be used.
3262 * configure.in: don't check for a command to extract errno codes.
3263 * Makefile.am: update file lists, remove errnos.list and errnos.c
3264 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
3265 check_errnos targets.
3266 (CLEANFILES): remove errnos.c and errnos.list, add
3267 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
3268 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
3269 * errnos.default: deleted.
3270 * cpp_signal.c: new file.
3271 * cpp_errno.c: renamed from errnos_get.c.
3272 * cpp_err_symbols, cpp_sig_symbols: new files.
3273 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
3274 * error.c (scm_init_error): #include cpp_err_symbols instead of
3276 * posix.c (scm_init_posix): don't intern signal symbols. #include
3279 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
3281 * strop.c (scm_i_index): allow the lower bound to be equal to the
3282 length of the string, so a null string doesn't always give an error.
3284 * posix.h: new prototypes.
3285 * posix.c (scm_status_exit_val, scm_status_term_sig,
3286 scm_status_stop_sig): new functions, as in scsh. They break down
3287 process status values as returned by waitpid.
3289 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
3291 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
3292 configure doesn't know about it.
3294 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3296 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
3298 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
3299 which defines C variables with global linkage.
3301 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3303 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
3306 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
3308 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
3309 has time to check why this doesn't work well with continuations.
3311 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
3313 * Fix shell syntax error; some shells won't tolerate
3314 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
3316 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3318 * posix.c (scm_uname): throw an error if uname fails instead
3321 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
3323 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
3326 * async.c (scm_ints_disabled): definition moved from error.c.
3328 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3330 * acconfig.h: Removed PACKAGE.
3332 * scmconfig.h.in: Regenerated.
3334 * snarf.h: g++ says it's non-portable not to specify the first
3335 argument in a varargs declaration. I introduced the first
3336 argument by using preprocessor conditionals.
3338 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
3340 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
3341 (scm_freopen): use RO string macros for filename and modes.
3342 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
3344 * posix.c (scm_getgrgid): simplify conversion of name to C string.
3345 (scm_mknod): use RO string macros for path.
3347 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
3348 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
3350 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
3351 use SCM_ROSTRINGP and SCM_ROCHARS.
3353 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3355 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
3358 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
3359 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
3360 support for byte vectors.
3362 * print.c (scm_iprin1): Limit number of vector elements printed
3363 according to pstate->length.
3365 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3367 * backtrace.c (scm_display_error_message): don't segv if message
3370 * error.h: prototype for scm_error_scm.
3372 * error.c (scm_error_scm): new procedure, reimplements scm-error
3373 in C and uses scm_error.
3375 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3377 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
3378 pointer to the Scheme variable read-hash-procedures and intern it
3379 in scm_init_read. Modify scm_read_hash_extend and
3380 scm_get_hash_procedure to use the pointer.
3382 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3384 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
3385 (SCM_KEYWORD_STYLE): defined.
3387 * read.c (scm_read_opts): add a keywords option. This isn't a
3388 boolean option, in case someone wants to add support for DSSSL
3390 Setup scm_keyword_prefix symbol.
3391 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
3393 I've left keyword support disabled by default, since it doesn't
3394 seem to break the module system and it gives R4RS standard behaviour.
3395 It can be reactivated with (read-set! keywords 'prefix).
3397 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3399 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
3400 before constructing arbiter.
3402 * eval.c (scm_m_define): Bugfix: Check that the object is a
3403 closure before setting the procedure property!
3405 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
3407 * ports.c: Removed `ungetc-char-ready?'.
3409 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
3411 * read.c (scm_init_read): intitialise scm_read_hash_procedures
3412 (idea from Mikael: make it a pair so scm_permanent object only
3414 (scm_read_hash_extend): don't call scm_permanent_object.
3415 (ideas from Mikael): if chr is already in the list, replace its
3416 procedure instead of appending it again. If proc is #f, remove
3418 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
3420 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
3422 * gdbint.c (gdb_read): update scm_lreadr usage.
3424 * load.h: update prototypes.
3426 * load.c (scm_primitive_load, scm_read_and_eval_x,
3427 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
3429 * read.h: add prototype for scm_read_hash_extend. Change args for
3432 * read.c (scm_read_hash_procedures): new variable.
3433 (scm_read_hash_extend): new procedure.
3434 (scm_get_hash_procedure): new procedure.
3435 (scm_lreadr): use scm_get_hash_procedure instead of an argument
3436 for extended # processing.
3437 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
3438 scm_read_token): remove case_i, sharp arguments. Change callers.
3440 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
3442 * read.h (SCM_N_READ_OPTIONS): increase to 3.
3443 (SCM_CASE_INSENSITIVE_P): define.
3445 * read.c: add case-insensitive option to scm_read_opts.
3446 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
3447 to determine whether to convert symbol case.
3448 (default_case_i): definition removed.
3449 * read.c (scm_read_token): if case_i, downcase ic before doing
3452 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3454 * configure.in: Added configuration option `guile-debug'.
3455 Configure with --enable-guile-debug if you want a bunch of extra
3456 functions used for debugging when developing Guile.
3458 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3460 * procs.c (make-cclo): New undocumented debugging procedure: Make
3461 compiled closure with internal procedure PROC and length LENGTH.
3462 Only compiled if GUILE_DEBUG is defined.
3464 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3466 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3468 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3470 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3471 with 3 or more args internally to the evaluator.
3473 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3475 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3476 with 3 or more args internally to the evaluator. This is mainly
3477 because we don't want to pass entry and exit points of the
3478 debug support twice, but it also seems to increase the speed of
3479 the evaluator for such calls (e. g. (+ 1 2 3)).
3481 * backtrace.c (scm_display_application): New procedure:
3482 display-application; Set fancy printing parameters individually
3483 for different types of display (backtrace, error, application).
3484 (These should of course be customizable!)
3486 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3487 clear the CHECK-flags.
3489 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3491 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3493 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3495 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3496 from pairs with a GLOC in the car.
3498 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3499 otherwise `symbol-hash' will behave badly.
3500 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3501 we get segmentation fault!
3503 * symbols.c: Added #include "weaks.h". New functions:
3504 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3505 moved to an extraneous library when we split libguile.)
3507 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3509 * filesys.c (scm_stat): stat now takes fport arguments too as
3510 documented in the manual.
3512 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3514 * debug.c (scm_single_step): Bugfix: Call continuation with
3515 scm_call_continuation instead of throwing to it.
3517 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3519 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3520 argument wasn't declared to be optional.
3522 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3524 * stime.c (scm_init_stime): Add feature "current-time".
3526 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3528 * throw.h: prototype for scm_exit_status.
3529 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3530 args to derive an exit status. Allows (quit) to work from a
3532 (scm_exit_status): new function.
3535 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3537 * eval.c (scm_deval): Removed some old code.
3538 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3540 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3543 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3546 * procs.c: Introduce the existent C function scm_thunk_p at the
3547 Scheme level as well.
3549 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3551 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3552 used from C to easily lookup the value of a symbol in the current
3555 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3557 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3558 scm_init_unif in this file. This will also fix a previous problem
3561 * configure.in: Added AM_MAINTAINER_MODE
3563 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3565 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3568 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3570 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3571 source files that are not always included in libguile but should
3572 have their dependencies calculated by automake. This variable is
3573 recognized by automake, no further magic is needed.
3574 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3575 to deal exclusively with *.lo files, as it seems. The *.o files
3576 are built automatically when the corresponding *.lo file gets
3579 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3581 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3584 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3586 * unif.c (scm_array_set_x): minor change to argument error checking.
3588 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3590 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3591 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3592 They should only be included in the library at configure.in's
3594 (libguile_la_LDADD): Include the appropriate .lo files here.
3595 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3596 so we know when to build them (and their .lo bretheren).
3597 * configure.in (LIBLOBJS): New substituted variable. We let
3598 configure decide which .o files to include in LIBOBJS, and then
3599 put the corresponding list of .lo files in LIBLOBJS. The latter
3600 is what we pass to libtool.
3601 * Makefile.in, configure: regenerated.
3603 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3605 * symbols.c (scm_sysintern0): New function. Contains the core of
3606 old scm_sysintern but doesn't take a second value argument.
3607 (scm_sysintern): Now uses scm_sysintern0.
3608 (scm_sysintern_no_module_lookup): Renamed to
3609 scm_sysintern0_no_module_lookup and doesn't take a second value
3610 argument any longer.
3612 * symbols.h (scm_sysintern0: Added declaration.
3614 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3615 scm_sysintern when interning option keys. Otherwise we risk
3616 destroying the values of already interned variables.
3618 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3619 scheme-level boolean (use SCM_NFALSEP).
3621 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3623 (scm_backtrace): New function. (C version of old function from
3624 boot-9.scm) Motivation: Make it possible to display backtraces
3625 without depending on boot-9.scm. (I'm uncertain if this
3626 motivation is good enough...)
3628 * root.h (scm_root_state): Add member the_last_stack_var.
3629 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3631 * root.c (mark_root): Mark scm_the_last_stack_var.
3633 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3636 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3638 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3639 1. mark_lazy_catch didn't mark the smob.
3640 2. Both functions above have standard variants:
3641 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3642 free_lazy_catch --> scm_free0.
3644 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3646 * throw.c (scm_internal_lazy_catch): New function.
3647 (scm_lazy_catch): Rewritten to use it.
3648 (scm_ithrow): Handle the new lazy catch representation.
3649 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3650 that doesn't have a jmpbuf is a lazy catch clause.
3651 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3652 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3653 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3655 (scm_init_throw): Register the new lazy-catch smob type.
3656 * throw.h (scm_internal_lazy_catch): decl for new function.
3658 * throw.c (scm_internal_catch): Doc fixes.
3660 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3661 configure.in. Including this might cause problems if applications
3662 that link against libguile include their own copies of alloca, but
3663 if they're using autoconf, they should be adding libguile to LIBS
3664 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3665 the copy in libguile, and things will be okay. (I think.)
3667 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3669 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3671 strop.h: move prototypes too.
3673 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3675 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3678 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3679 etc. I deleted them from filesys.c long ago, but didn't
3680 notice they were here too (although ineffective since
3681 sys/stat.h wasn't included).
3683 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3685 * eval.c: Don't define alloca in GCC case. gcc will automatically
3686 use __builtin_alloca if appropriate.
3688 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3690 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3691 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3692 that values of automatic variables are preserved. See comments
3693 for safe_setjmp for details.
3695 Change from Thomas Morgan:
3696 * variable.c: Include eq.h.
3697 (var_equal): New function.
3698 (variable_smob): Use var_equal as the discriminator for variables.
3700 * throw.c (s_throw): Remove extraneous declaration.
3702 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3703 * eval.c: Add necessary CPP cruft to support that.
3704 * configure, Makefile.in, scmconfig.h.in: regenerated.
3706 Change from Thomas Morgan:
3707 * procprop.c (scm_procedure_properties): Convert the Scheme
3708 boolean returned by scm_procedure_p into a C boolean before using
3709 it as a condition for SCM_ASSERT.
3710 (scm_procedure_property): Likewise.
3712 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3713 indications of Unixness.
3716 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3718 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3720 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3722 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3723 "unknown # object" error messages.
3725 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3726 (scm_i_index) and declare it static. Add a 'direction' argument
3727 to indicate what way the search should go.
3728 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3730 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3731 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3733 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3735 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3737 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3738 to avoid clash with various scsh forks.
3740 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3742 The following two changes (ramap.c, throw.c) are motivated by the
3743 apparent unportability of forward declarations of static arrays of
3744 the form `static foo bar[];'.
3746 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3747 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3749 * throw.c (scm_throw): Moved above scm_ithrow.
3751 * options.h: Removed the extern declarations of scm_yes_sym and
3752 scm_no_sym since these are static.
3754 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3756 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3758 * Makefile.am: remove AWK=@AWK@.
3759 Add a rule for generating errnos.list.
3760 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3762 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3763 don't extract errnos, just set a variable (avoids the
3764 need to recompile error.c just because configure is run.)
3766 * unif.h: update prototypes.
3767 * unif.c (scm_uniform_array_read,write): change the offset and
3768 length arguments to start and end, for consistency.
3770 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3772 * ioext.h: update prototypes.
3773 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3774 scm_read_line_x, it's a more general procedure using an
3775 interface from scsh. read-line and read-line! are now defined
3777 Note that the new read-line trims the terminator
3778 by default, previously it was appended to the returned string. An
3779 optional argument specifies how to process the terminator (scsh
3780 compatible). For the old behaviour: (read-line port 'concat).
3781 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3782 returns a pair, but is converted to multiple values if the scsh
3785 socket.h: update prototypes.
3786 * socket.c (scm_recvfrom): for consistency with other procedures,
3787 take start and end as separate optional arguments.
3788 (scm_recv, scm_recvfrom): don't allow the second argument
3789 to be a size, only a buffer. Change the scheme names to
3790 recv! and recvfrom!. Don't return the buffer.
3792 * ioext.h, posix.h: move prototypes too.
3793 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3794 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3795 "read.h" and "unif.h".
3796 * ioext.c: include "chars.h"
3798 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3800 * dynl.c: The dynamic linking and module registration functions
3801 are now defined even when dynamic linking is not available for the
3802 host system. Some of their functionality can be done without
3803 dynamic linking; when it's really needed, they throw errors.
3805 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3807 * configure.in: Only define DYNAMIC_LINKING when one of the system
3808 dependent functions is detected.
3809 * dynl.c (scm_dynamic_func): New function to get the address of a
3810 function in a dynamic object.
3811 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3812 produced by scm_dynamic_func as the thing to call.
3814 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3816 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3817 (scm_register_module_xxx, scm_registered_modules,
3818 scm_clear_registered_modules): New functions.
3820 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3822 * symbols.c (scm_sysintern): Renamed to
3823 scm_sysintern_no_module_lookup.
3824 (scm_sysintern): New function to take the place of the old
3825 scm_sysintern. It uses the current toplevel lookup closure to give
3826 the symbol its value. This is a temporary hack to put packages
3827 like gtcltk into their own module.
3828 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3829 us whether `scm_top_level_lookup_closure_var' has been initialized
3831 * eval.c (scm_init_eval): Set it.
3833 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3835 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3836 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3838 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3840 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3841 scm_sys_dup): deleted: FD capability will be added to other
3843 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3844 scm_fd_free, fd_smob, scm_intern_fd.
3845 (scm_open): renamed from scm_sys_open. Return a port instead of
3846 an FD object. Make the mode argument optional.
3847 (scm_sys_create): deleted, it's just a special case of open.
3848 (scm_init_filesys): move interning of constants O_CREAT etc.,
3849 here (were previously using SCM_CONST_LONG macro).
3850 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3852 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3853 include "fports.h" and <stdio.h>
3854 (scm_stat, scm_select): don't support FD objects.
3856 * error.h: adjust scm_syserror_msg prototype.
3857 * error.c (scm_syserror_msg): take an extra argument for errno.
3858 Using the global value didn't always work, since it could be
3859 reset by procedure calls in the message or args arguments.
3861 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3862 I don't understand why the check was there (and what about the
3865 * strop.c (scm_string_copy): allow shared substrings to be copied.
3867 * unif.h: corresponding change to prototypes.
3868 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3869 recognize two new optional arguments: offset and length. Allow
3870 the port argument to be an integer (file descriptor, for scsh).
3871 Include <unistd.h> for "read" prototype.
3873 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3875 * socket.c: don't include filesys.h.
3877 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3879 * Makefile.am: add AWK=@AWK@ (?)
3881 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3883 Add a rule to generate errnos.c from errnos.
3884 * error.c (scm_init_error): include errnos.c.
3885 * errnos_cnvt.awk: new file, converts the list of errno codes to
3887 * errnos_get.c: new file.
3888 * errnos.default: new file, contains errnos to try if they can't
3889 be extracted from errno.h.
3890 * configure.in: if using GCC, try and extract errno codes from
3894 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3896 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3897 * Makefile.am: Made libguile into a libtool library.
3898 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3899 Set libtool_libs to indicate that libguile is a libtool library.
3900 See guile/ChangeLog for details.
3901 * .cvsignore: ignore "*.lo", the libtool library objects.
3903 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3905 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3906 use htons in getservbyport argument.
3908 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3910 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3911 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3914 * objprop.c (scm_object_property): No need to take the CDR of the
3915 value returned by scm_object_properties, since Aug 20 change.
3917 * configure.in: When checking for struct linger, #include
3918 <sys/types.h> as well as <sys/socket.h>. I've never known
3919 <sys/types.h> to cause any portability problems, and Solaris's
3920 <sys/socket.h> needs it.
3921 * configure: Rebuilt.
3923 I think the Sun compiler has chosen a perverse way to interpret
3924 ANSI declarations combined with K&R definitions. We'll
3925 appease it a little bit. But when it invades France, we fight.
3926 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3927 * print.h (scm_iprlist): Here too.
3928 * numbers.c (scm_divbigdig): Change definition to match
3929 declaration in numbers.h.
3930 * unif.c (scm_makflo): Change definition to match declaration in
3933 * init.c (scm_boot_guile): Don't return the value of
3934 scm_boot_guile_1. This function doesn't return a value;
3935 scm_boot_guile_1 doesn't return a value (or return at all).
3937 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3940 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3941 compile. I have a feeling this function is a bad idea anyway ---
3942 one should always test for features, not systems.
3944 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3945 semicolons. Only pure luck kept this from being noticed earlier.
3947 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3949 * socket.c (scm_recvfrom): Added missing semicolon.
3951 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3953 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3954 the buffer and start and end positions for scsh networking
3957 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3959 * configure.in: Revert previous change to this file; the problem
3960 is due to transient automake weirdness.
3961 * configure: Rebuilt.
3963 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3964 PLUGIN/guile.libs. configure generates the latter from the former.
3965 * Makefile.in: Rebuilt.
3967 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3968 need this if we install scripts, like guile-snarf.
3969 * configure: Rebuilt.
3971 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3973 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3975 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3977 * socket.c (scm_addr_vector): fix faulty scm_listify.
3979 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3981 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3982 style block comment is no longer considered an error.
3984 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3986 * PLUGIN/guile.libs.in: New file.
3987 * PLUGIN/guile.libs: Removed from repository.
3988 * configure.in: Create PLUGIN/guile.libs from
3989 PLUGIN/guile.libs.in. This is for including additonal libraries
3990 needed for dynamic linking.
3991 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3992 instead of PLUGIN/guile.libs.
3994 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3996 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3998 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3999 occurrences of the given element from the list, not just the
4000 first. This is how the Emacs Lisp functions behave, how the
4001 analogous Common Lisp functions behave, and (I believe) how the
4002 older Maclisp functions worked. I realize that this change may
4003 break code, but it seemed better to break it before the Guile
4006 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
4007 Their prototypes were already present in gc.h, but they weren't
4009 (scm_init_storage): Initialize scm_protects.
4010 * root.c (scm_protects): New element of scm_sys_protects.
4012 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
4014 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4016 * libguile.h: Added #include "libguile/net_db.h".
4018 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
4019 30 change. That file is only meant for communication between the
4020 configuration process and load.c. If code linked against libguile
4021 wants to get at the paths mentioned in libpath.h, it can call
4022 functions declared in load.h.
4024 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4026 * libguile.h: Removed #include "libguile/fdsocket.h"
4028 * net_db.c: Added #include <sys/socket.h>.
4030 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
4032 * filesys.c (scm_input_waiting_p): use select in preference to
4033 FIONREAD, since the latter doesn't detect EOF.
4034 Throw error if neither select nor FIONREAD available.
4036 * socket.c (scm_connect): take a port, not a fd object.
4037 (scm_fill_sockaddr): throw an error if fam is not recognised.
4038 (scm_bind): use scm_fill_sockaddr.
4039 (scm_listen): take a port, not a fd object.
4040 (scm_accept): take and return a port. return #f in the car if
4041 address can't be got
4042 (scm_sock_fd_to_port): new procedure.
4043 (scm_socket): use scm_sock_fd_to_port.
4044 (scm_addr_vector): throw error if unrecognised address type.
4045 take an extra argument with the calling procedure name.
4046 (scm_getsockname): take a port. return #f if address can't be got.
4047 (scm_getpeername): take a port. return #f if address can't be got.
4048 (scm_recvfrom): take a port. return #f for address component if can't
4050 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
4051 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
4053 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
4055 * throw.c (scm_internal_catch): Make body funcs and handler funcs
4056 use separate data pointers, to allow them to be designed
4057 independently and reused.
4058 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
4059 Renamed from catch_body, catch_handler, and uncaught_throw; made
4061 (struct scm_catch_body_data): Renamed from catch_body_data; moved
4063 (scm_catch): Use the above.
4064 (scm_throw): Don't bother printing a message for an uncaught
4065 throw; we establish a default handler in init.
4066 * throw.h (scm_internal_catch): Prototype updated.
4067 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
4069 (struct scm_body_thunk_data): New structure, used as data
4070 argument to scm_body_thunk.
4071 * init.c (struct main_func_closure): New structure, packaging up
4072 the data to pass to the user's main function.
4073 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
4074 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
4075 scm_internal_catch to establish a catch-all handler, using
4076 scm_handle_by_message. This replaces the special-case code in
4078 (invoke_main_func): Body function for scm_internal_catch; invoke
4079 the user's main function, using the main_func_closure pointer to
4080 decide what to pass it.
4081 * root.c (struct cwdr_body_data): Remove handler_proc member.
4082 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
4083 (cwdr_handler): Removed.
4085 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4087 * socket.h (SCM_P): update bind prototype.
4088 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
4089 include "feature.h".
4090 (scm_socket): return a port, not a file descriptor object.
4091 include "fports.h" and <unistd.h>
4092 (scm_bind): take a port, not a file descriptor object.
4093 take an extra argument for address args.
4095 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
4096 INADDR_NONE, INADDR_LOOPBACK.
4098 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4100 * init.c: include net_db.h and not fdsocket.h.
4101 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
4103 * Makefile.am: corresponding changes.
4104 * socket.h: renamed from fdsocket.h, fix names.
4105 * net_db.h: renamed from socket.h, fix names.
4106 * socket.c: renamed from fdsocket.c.
4107 remove _sys from procedure names.
4108 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
4109 add "socket" to features list.
4110 * net_db.c: renamed from socket.c.
4111 remove _sys from procedure names.
4112 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
4113 add "net-db" to features list.
4114 include "net_db.h". don't include <sys/socket.h> or
4117 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4119 * tags.h (scm_tags): Removed comma at end of last enumerator.
4121 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
4123 Don't use GCC extensions to allocate space for debugging frames.
4124 (Here he goes again! Why do we put up with this?!)
4125 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
4126 an scm_debug_info structure, not an in-line array of them. Add
4127 'info' member, to say how many vect elements we've used, for eval
4129 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
4130 a new variable debug_info_end to mark the end of vect, instead of
4131 the address of the 'info' pointer itself.
4132 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
4133 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
4134 (SCM_APPLY): Explicitly allocate space for debug.vect.
4135 * debug.c (scm_m_start_stack): Same, for vframe.vect.
4136 * stacks.c: Adjusted for new debug frame structure.
4137 (RELOC_INFO, RELOC_FRAME): New macros.
4138 (stack_depth, read_frames): Use them, and new scm_debug_frame
4139 element 'info', instead of magically knowing that eval frames have
4140 an info pointer sitting after vect.
4141 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
4143 (scm_init_stacks): Formatting tweaks.
4145 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
4147 Give GCC more control flow information, so it can be sure that
4148 variables aren't used uninitialized.
4149 * error.h (scm_error, scm_syserror, scm_syserror_msg,
4150 scm_sysmissing, scm_num_overflow, scm_out_of_range,
4151 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
4152 scm_misc_error): Tell GCC that these functions never return.
4153 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
4154 out the field type, call abort if SCM_ASSERT returns, to placate
4156 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
4157 scm_wta ever returns. We can't handle this case anyway, and this
4158 gives the optimizer more information.
4159 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
4160 scm_wta ever returns.
4162 In some cases, the code is fine, but GCC isn't smart enough to
4163 figure that out; this usually happens when one variable is only
4164 initialized and used when a particular condition holds true, and
4165 we know that condition will never change within a given invocation
4166 of the function. In this case, we simply initialize the variables
4167 to placate the compiler, hopefully to a value which will cause a
4168 crash if it is ever actually used.
4169 * print.c (scm_iprin1): Initialize mw_pos.
4170 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
4171 * throw.c (scm_ithrow): Initialize dynpair.
4172 * unif.c (scm_uniform_vector_ref): Initialize cra.
4173 * struct.c (init_struct): Initialize prot.
4174 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
4176 * strports.c (scm_eval_0str): Don't return uninitialized garbage
4177 if EXPR contains no expressions.
4179 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
4181 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
4182 cause an infinite loop (???). So much for the algebraic
4183 equivalency of variable-sized arrays and alloca...
4185 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
4187 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
4188 a SCM boolean, not a C boolean.
4190 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
4192 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
4193 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
4194 rules for raising scm_mtrigger. Previously, unfortunate but not
4195 unlikely circumstances could result in almost constant invokation
4196 of the gc. Now, this situations should be less likely, but they
4197 are not prevented completely.
4199 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
4201 * numbers.c (scm_fuck): Procedure removed; looks like old test
4203 * numbers.h: Prototype removed.
4205 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
4207 * debug.h (scm_debug_frame): Change `vect' member from an in-line
4208 array to a pointer, to match my Nov 21 change in eval.c.
4210 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4212 * libguile.h: Added #include "libguile/backtrace.h", #include
4213 "libguile/stacks.h".
4215 * strings.c (scm_string scm_make_string scm_string_ref
4216 scm_string_set_x scm_string_equal_p scm_string_append):
4217 Bugfix according to scm patch from Aubrey Jaffer:
4218 Corrected long-standing
4219 (not (eqv? (integer->char 128)
4220 (string-ref (make-string 1 (integer->char 128)) 0)))
4221 bug found by John Kozak <jk@noontide.demon.co.uk>.
4223 * strports.c, strports.h: Make scm_eval_0str return the value of
4224 the last expression evaluated (previously, it returned void).
4226 * strports.c, strports.h: New function: scm_read_0str. Does what
4229 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4231 * simpos.c (scm_getenv): return #f if string can't be found in the
4232 environment instead of throwing an exception, for compatibility
4233 with numerous other systems.
4235 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
4237 * Makefile.am (.c.x): Use guile-snarf.
4238 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
4240 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
4242 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4244 * backtrace.c (scm_display_error_message): Made non-static, and
4245 renamed from display_error_message.
4246 * backtrace.h (scm_display_error_message): Added extern decl.
4247 * throw.c (uncaught_throw): Use it to display the error message.
4249 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
4251 * inet_aton.c: Use #if 0, not #ifdef 0.
4253 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
4255 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
4256 to convert the returned value.
4257 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
4258 the offset argument.
4260 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4262 Add new interface to catch/throw, usable from C as well as
4264 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
4265 (scm_internal_catch): New function, replaces...
4266 (scm_catch_apply): Deleted.
4267 * throw.c (scm_catch_apply): Deleted; replaced with a more general
4268 mechanism which is a bit more code, but can be used nicely from C
4269 and implement the Scheme semantics as well.
4270 (scm_internal_catch): This is the replacement; it's named after
4271 the analogous function in Emacs.
4272 (scm_catch): Reimplemented in terms of the above.
4273 (struct catch_body_data, catch_body, catch_handler): New
4274 functions, used by scm_catch.
4275 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
4276 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
4277 support for new cwdr.
4279 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
4282 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
4284 * acconfig.h: Added DYNAMIC_LINKING symbol.
4285 * configure.in: Add option and checks for dynamic linking.
4286 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
4287 dynl.h: New files for dynamic linking support.
4288 * Makefile.am (libguile_a_SOURCES):
4290 (modinclude_HEADERS): Added "dynl.h".
4291 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
4293 * init.c (scm_boot_guile_1): Call
4294 scm_init_dynamic_linking to initialize dynamic linking support.
4296 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
4298 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
4299 (as we Schemers say). It needs to be global, so that I can tweak
4300 it for the proper operation of unexec.
4301 (scm_boot_guile_1_live): New variable, see above.
4303 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
4305 * guile-snarf.sh: Removed.
4306 * PLUGIN/guile.libs: Added dependency for -lm.
4307 * acinclude.m4: Renamed from aclocal.m4.
4308 * PLUGIN/greet: Removed.
4309 * Makefile.am, aclocal.m4: New files.
4310 * configure.in: Updated for Automake.
4312 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
4314 * eval.c (scm_definedp): Use top_level_lookup_closure_var
4315 and not top_level_lookup_thunk_var.
4317 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
4319 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
4321 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
4323 * eval.c (scm_definedp): Incompatibly changed to be a builtin
4324 Scheme function, instead of syntax. Single argument is now a
4327 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4329 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
4330 scm_ra_divide): Properly terminate statements passed as arguments
4331 to IVDEP macros. (Thanks to Bernard Urban.)
4333 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
4334 with non-constant sizes. (Thanks to Bernard Urban.)
4336 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4338 It's an "eval closure", not an "eval thunk." A thunk is a
4339 function of no arguments.
4340 * root.h (struct scm_root_state): Renamed
4341 top_level_lookup_closure_var from top_level_lookup_thunk_var.
4342 (scm_top_level_lookup_closure_var): Renamed from
4343 scm_top_level_lookup_thunk_var.
4344 * root.c (mark_root): Uses changed.
4345 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
4346 * init.c (scm_start_stack): Uses changed.
4347 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
4348 Change scheme-visible name to *top-level-lookup-closure* from
4349 *top-level-lookup-thunk*.
4351 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
4353 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
4354 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
4356 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
4358 * gc.c (struct scm_heap_seg_data): Doc fixes.
4360 * gc.c (scm_gc_sweep): Empty all segments' freelists before
4361 sweeping. Then, prepend each segment's free cells to its
4362 freelist, rather than wiping out the old value. (Thanks to Marius
4365 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
4366 scm_check_freelist, scm_debug_newcell): New functions and
4367 variables, for debugging freelist problems.
4368 * pairs.h (SCM_NEWCELL): New debugging version added.
4369 * gc.h (scm_debug_newcell): Added extern declaration, used by
4370 debugging version of SCM_NEWCELL.
4372 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4374 On some systems <libc.h> conflicts with <unistd.h>, and should not
4375 be #included at all.
4376 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
4377 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
4378 * configure.in: Call it.
4379 * posix.c, filesys.c: Use its results to decide whether or not to
4381 * configure, scmconfig.h.in: Rebuilt with autoconf and
4384 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4386 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
4387 pointer to the stdio stream before calling scm_setbuf0, so the
4388 latter will be able to retrieve it. I'm surprised this didn't
4389 segfault earlier. (Thanks to Christopher Lee.)
4391 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4393 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
4396 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4398 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
4399 number of stack narrowing specifier pairs. The first specifier in
4400 a pair controls inner border, the second the outer border. A
4401 number means cut that number of frames, a procedure object means
4402 cut until that object is found in operator position in a frame.
4404 * root.c (cwdr): Bugfix.
4406 * read.c: Recording of positions disabled by default.
4408 * procs.c (scm_closure_p): New function.
4410 * posix.c (scm_tmpnam): New function.
4412 * load.c: Added #include "throw.h".
4413 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
4416 * load.c, load.h (scm_read_and_eval_x): New function.
4418 * eval.c: Renamed debug option "deval" to "debug".
4420 (scm_eval_x): `eval!' is no longer accessible from the scheme
4421 level. Motivation: We can't allow operations which introduce
4422 glocs into the scheme level. Guile's type system can't handle
4423 these as data. Use `eval' or `read-and-eval!' as replacement.
4425 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
4426 SCM_CONSP since this is a macro!; Set vframe.prev to
4427 scm_last_debug_frame instead of 0. In this way we can look
4428 "above" the virtual start stack frame if we wish.
4429 (scm_debug_hang): New function: Useful for debugging Guile in
4430 certain tricky situations. Will probably be removed later...
4432 * debug.h: Changed semantics of debug option "backtrace". This
4433 option now only indicates whether we want automatic backtrace at
4436 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4438 * ports.c: #include "filesys.h"
4439 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
4441 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
4442 Motivation: This is system specific code which is related to file
4443 I/O. It also may use select. Added code by Gary Houston to
4444 detect presence of character in stdio buffers.
4446 * libguile.h: #include "libguile/libpath.h"
4448 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4449 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4450 SCM_SITE_DIR; Install libpath.h among the other include files.
4452 * load.c, load.h (scm_sys_package_data_dir): New function.
4454 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4456 * stacks.h: Bugfix: Don't use tail-array length field as stack
4457 length field! This screwed GC.
4459 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4461 * _scm.h: Added #ifndef around definition of macros min and max.
4463 * __scm.h: Added hooks for threads to plugin to in ints protection
4464 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4465 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4466 the main code in these macros duplicated and spread over multiple
4467 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4468 SCM_THREAD_SWITCHING_CODE.
4470 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4472 * snarf.h: New file.
4473 * guile-snarf.sh: New file.
4474 * Makefile.in (inner_h_files): Added snarf.h
4475 (ancillary, install, uninstall, distclean): Added actions for
4477 (.c.x): Use guile-snarf.
4478 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4479 (gen_c_files): Note that these depend on guile-snarf.
4480 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4481 now in "snarf.h". Added #include "snarf.h" to get them.
4482 * libguile.h: Added #include "snarf.h".
4483 (Patches applied and tweaked by Jim Blandy.)
4485 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4487 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4488 standards suggest against providing prototypes for system
4489 functions. Thanks to Greg Troxel.
4491 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4493 * strports.c (scm_eval_0str): New function.
4494 #include "read.h", to get prototype for scm_read.
4495 * Makefile.in (strports.o): Update dependencies.
4496 * strports.h: New prototype.
4498 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4499 scheme name from "int?" to "integer?". It seems to do the job.
4500 * numbers.h: Rename prototype too.
4501 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4504 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4505 scm_num_eq_p): Rename these according to R4RS conventions: call
4506 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4507 to making libguile R4RS compliant without ice-9...
4509 * load.c (scm_sys_search_load_path): Search for files under all
4510 extensions listed in the %load-extensions variable. If FILENAME
4511 is absolute, return it unchanged, without searching the load path.
4512 (scm_loc_load_extensions): New variable, pointing to
4513 %load-extensions' value cell.
4514 (scm_init_load): Initialize it, and the value it points to.
4515 (scm_primitive_load_path): Improve error reporting.
4517 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4518 of new Scheme variable %load-hook.
4519 (scm_primitive_load): Apply %load-hook to filename.
4521 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4523 * configure.in: add tests for figuring out whether buffered data
4524 is available in a FILE structure, which is needed by char-ready.
4526 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4529 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4530 exceptions using misc_error instead of syserror. It seems a bit
4531 odd to throw an exception if a string can't be found in the
4532 environment, but it's consistent with open-file, stat etc.
4533 (simpos.h): remove sys_ from getenv.
4535 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4536 occurs, throw an error instead of returning errno. Return value
4538 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4540 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4542 * filesys.c (scm_stat2scm): derive file type and permissions from
4543 the stat mode and append them to the returned vector.
4544 There isn't much overhead in doing this and it avoids the need to
4545 work with S_IRUSR et al. in Scheme.
4546 Define symbols scm_sym_regular etc.
4547 (scm_init_filesys): don't intern S_IRUSR etc.
4549 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4550 and s_primitive_load_path.
4552 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4554 * error.h: don't declare error symbols. prototype for scm_misc_error.
4556 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4559 * error.c: use SCM_SYMBOL to set up error keys.
4560 scm_misc_error: new procedure.
4562 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4564 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4565 between `#!' and `!#' is ignored.
4566 (skip_scsh_block_comment): New function.
4568 * feature.c (scm_set_program_arguments): New argument, FIRST.
4569 * feature.h: Update prototype.
4570 * init.c (scm_boot_guile_1): Pass new argument to
4571 scm_set_program_arguments.
4573 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4575 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4576 (scm_boot_guile): Call scm_set_program_arguments here, later than
4577 the old initialization.
4579 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4580 initialization procedure.
4581 - Delete in, out, err arguments; there are other perfectly good
4582 ways to override these when desired.
4583 - Delete result argument; this function shouldn't ever return.
4584 - Rename init_func argument to main_func, for less confusion.
4585 - Delete boot_cmd argument; main_func is more general.
4586 -Add 'closure' argument, to help people pass data to main_func
4587 without resorting to global variables.
4588 - Abort if reentered; don't bother returning an error code.
4589 - Call scm_init_standard_ports to set up the default/current
4590 standard ports; no need to pass them to scm_start_stack.
4591 - Remove code to evaluate the boot_cmd, and start the repl; let
4592 the user do something like that in main_func if they want.
4593 - Remove code to package up a return value; main_func can do any
4595 - Call exit (0), instead of returning.
4596 (scm_start_stack): Don't initialize the I/O ports here; that's
4597 weird. Delete in, out, err arguments. Move guts to
4598 scm_init_standard_ports, scm_stdio_to_port.
4599 (scm_init_standard_ports): New function, to set up current and
4600 default standard ports.
4601 (scm_start_stack, scm_restart_stack): Make these static.
4602 * init.h (scm_boot_guile): Adjust declaration.
4603 (scm_start_stack, scm_restart_stack): Remove externally
4604 visible declarations for these.
4605 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4607 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4608 written out several times in scm_start_stack.
4609 * fports.h: New declaration for the above.
4611 * feature.c (scm_set_program_arguments): New function.
4612 * feature.h: New declaration for the above.
4614 * ports.c: Formatting tweak.
4616 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4618 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4619 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4620 for obtaining the address of a car or cdr field. Motivation:
4621 &SCM_CXR make assumptions about the internal structure of the
4624 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4625 Motivation: see SCM_CXRLOC.
4627 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4628 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4629 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4630 Motivation: Safer use. Some other macros are defined in terms of
4631 these operations. If these are defined using the SCM_SETCXR
4632 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4633 to inefficiency and an <e1> with side-effects could potentially
4634 break. Also, these particular operations are heavily utilized in
4635 the garbage collector. In unoptimized code there will be a
4638 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4639 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4640 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4641 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4642 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4643 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4644 vports.c: Cleaned up use of pairs: Don't make any special
4645 assumptions about the internal structure of selectors and
4646 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4647 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4648 (Among other things, this change makes it easier to build Guile
4649 with certain compilers which have problems with casted lvalues.)
4651 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4653 * stacks.c: Improve selection of relevant stack frames when making
4654 a stack object. Introduce one level of indirection in the stack
4655 object to make it possible to "narrow" to a certain region of the
4656 stack. This facilitates making use of more clever algorithms (not
4657 implemented) for selecting relevant frames and gives a cleaner
4658 design since selection of frames can be done independently of
4659 extraction of frames from the real stack.
4660 (scm_stack_id): Also take #t as argument which means look at
4663 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4664 Turn n_tail into an integer directly representing current number
4665 of frames in stack. Add field tail.
4667 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4669 * debug.c (scm_make_memoized): Made it available at scheme level.
4670 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4671 SCM_NIMP before applying heavier predicates in argument checking.
4672 (scm_local_eval): Also take memoized object as argument.
4674 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4675 aren't created with zero length, but should such a strange
4676 creature suddenly turn up...
4678 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4680 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4681 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4683 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4685 * variable.c (scm_make_variable): Make the name hint optional, as
4687 (anonymous_variable_sym): Renamed from variable_sym. All uses
4690 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4691 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4692 of scm_primitive_load_path was also changed to
4693 "primitive-load-path", from "%try-load-path". Callers changed.
4694 We'd like to respect the convention that a function named
4695 "try-mumble" should behave just like the function called "mumble",
4696 but return #f instead of signalling some error.
4697 * load.h: Rename prototypes.
4699 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4701 * print.c (make_print_state, grow_print_state), print.h: Modified
4702 the print state representation: Don't use a tail array for
4703 recording of circular references. Resizing of the print state
4704 structure invalidates the print state pointer. To avoid passing
4705 around an indirect print state reference to all printing
4706 functions, we instead let the print state reference a resizable
4709 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4711 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4712 Don't crash when passed an improper list terminated by a
4713 non-immediate value.
4715 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4717 Allocate data for structures on an eight-byte boundary, as
4718 required by the tagging system.
4719 * struct.c (alloc_struct): New function.
4720 (scm_make_struct, scm_make_vtable_vtable): Call it.
4721 * struct.h (scm_struct_n_extra_words): Bump to 3.
4722 (scm_struct_i_ptr): New "field".
4723 * gc.c (scm_gc_sweep): When we need to free the data, use the
4724 information stored by alloc_struct to find the beginning of the
4725 block allocated to the structure, so we can free it.
4727 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4729 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4732 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4733 (scm_debug_info): New member: id.
4735 * stacks.c: Stacks are now represented as structs; Stacks have an
4736 id given to them by `start-stack'.
4737 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4739 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4740 Changed stack representation.
4742 * debug.c (scm_procedure_name): Try procedure property `name' for
4743 compiled closures aswell.
4745 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4747 * eval.c: scm_i_name moved to gsubr.c
4748 (scm_m_define): Record names of all kinds of procedure
4749 objects. (Earlier, only closures were recorded.)
4751 * procprop.h: Added declaration of scm_i_name.
4753 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4754 (scm_make_gsubr): Record names of compiled closures.
4756 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4758 * debug.c, debug.h: Removed obsolete code.
4760 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4761 stacks.c: Renamed regs --> scm_contregs.
4763 * print.c (scm_free_print_state): Cleanup print state before
4764 returning it to pool. It is better to do it here than in
4765 scm_prin1 since scm_prin1 is called often.
4767 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4768 s_set_source_property_x): Check that first argument is a pair or a
4771 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4772 scm_i_line, scm_i_column and scm_i_breakpoint global.
4774 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4775 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4778 * debug.h: Added debug object smob declaration and macro
4781 * configure.in: Build with backtrace.o and stacks.o if debug
4784 * Makefile.in: Added entries for new files: backtrace.c,
4785 backtrace.h, stacks.c and stacks.h.
4787 * symbols.c (scm_sym2ovcell): Fixed documentation.
4789 * _scm.h (min, max): Added.
4791 * async.c: Moved `min' macro to _scm.h.
4793 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4794 SCM_BACKTRACE_INDENT.
4796 * eval.c: Added new debug options `maxdepth' and `indent'.
4798 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4800 * print.h: Added selector SCM_PRINT_STATE.
4802 * print.c: New functions: scm_make_print_state,
4803 scm_free_print_state.
4805 * print.h: Added declarations for scm_make_print_state,
4806 scm_free_print_state.
4808 * debug.c (scm_m_start_stack): New acro.
4810 * debug.h: Small cleanup.
4812 * init.c (scm_boot_guile_1): Moved scm_init_debug below
4815 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4817 * __scm.h, alist.c, alist.h, append.c, append.h, appinit.c,
4818 arbiters.c, arbiters.h, async.c, async.h, boolean.c, boolean.h,
4819 chars.c, chars.h, continuations.c, continuations.h, debug.c,

4840 More prototype-related changes from Marius Vollmer:
4841 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4842 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4843 * ports.h (ptobfuns): Added prototypes. This means some casting in
4845 * fports.c: Added casts for initializations, since the functions
4846 are defined to take FILE * as their stream argument, not SCM.
4847 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4848 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4849 to `char *str_data' to conform to prototype.
4851 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4853 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4855 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4857 * stime.c, stime.h: use SCM_P method.
4859 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4861 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4862 be given at least two arguments. Insist that lst's last element
4863 be a list, but don't make any requirements of its predecessors.
4865 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4867 * eval.c (scm_nconc2last): Revert last change; there seems to be
4868 other stuff going on here.
4870 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4872 * eval.c (scm_nconc2last): Make sure that each element of lst
4873 (which is a list of argument lists, except for the tail) is a
4874 proper list, i.e., finite and terminated by '().
4876 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4878 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4881 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4882 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4885 * vectors.c (scm_make_vector): Fill vectors with the undefined
4886 value, to help make Guile Scheme code more portable to other
4889 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4890 * symbols.h, tags.h: Doc fixes.
4892 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4894 * async.c (scm_take_signal): Doc fixes.
4896 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4898 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4899 want to subtract it from the modulus; we just want to leave it
4902 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4904 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4907 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4909 * throw.c (scm_catch_apply): Finished implementation of
4912 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4914 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4916 (scm_init_filesys): set "i/o-extensions" feature.
4919 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4921 * Makefile.in (root.o): Correct dependencies.
4923 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4925 * Makefile.in: Added dependency entry for root.o.
4927 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4928 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4930 * init.c (scm_start_stack): Set initial root continuation number
4933 * procs.c: New function: scm_thunk_p.
4935 * procs.h: Added declarations of scm_thunk_p.
4937 * root.c: Renamed `call-with-new-root' -->
4938 `call-with-dynamic-root'.
4939 (cwdr): Removed allocation of new root state. This should be done
4940 separately by use of scm_make_root.
4941 (scm_apply_with_dynamic_root): New function: Does what it
4942 sounds like. Needed when spawning threads.
4944 * root.h: Added member last_debug_frame to root state.
4945 Added #include "libguile/debug.h"
4947 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4948 arguments. The motivation is that code in root.c needs catch
4949 functionality, and we want to avoid code duplication.
4950 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4951 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4952 handlers that run without popping the stack into the dynwind
4955 * throw.h: Added prototypes for scm_catch_apply and
4958 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4960 * root.h (scm_root, scm_set_root): Decouple thread support details
4961 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4962 SCM_SET_THREAD_LOCAL_DATA.
4964 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4965 and tortoise scanning loop.
4967 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4969 * Makefile.in: Rebuild dependencies.
4971 * libguile.h: #include "libguile/print.h" before "smob.h", since
4972 the latter uses the print_state structure.
4974 * throw.c (scm_ithrow): Use the correct variable when checking to
4975 see if a given element of scm_dynwinds is a valid catch.
4977 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4978 structure, abort; don't just silently ignore the garbage.
4980 * _scm.h: #include "print.h" here, since it seems to be used just
4982 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4983 strports.c, unif.h: Don't #include "print.h".
4985 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4987 * feature.h (scm_loc_features): Removed external declaration.
4988 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4990 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4992 * feature.c (scm_init_feature): Added threads feature (needs to be
4993 initialized here, since features doesn't exist when
4994 scm_init_threads is called).
4996 * libguile.h: Added #include "libguile/../threads/threads.h".
4997 (This is a kludge to get thread support working. This should be
5000 * configure.in, acconfig.h: Added flags for thread support.
5002 * scmsigs.c: Define `signal' to be `pthread_signal' if using
5005 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
5006 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
5009 * _scm.h: Added conditional #include "threads.h"
5011 * __scm.h (SCM_ASYNC_TICK): Added call to macro
5012 SCM_THREADS_SWITCHING_CODE.
5014 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
5015 allocate the basic dynamic root object.
5016 (scm_boot_guile): Added call to scm_init_root.
5018 * root.c, root.h: Added root smob.
5019 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
5020 functions: Implements dynamic roots mostly according to spec in
5021 SCM manual. Main difference is that the second argument is a
5022 throw handler rather than an error "thunk".
5024 * root.h: Added declaration of scm_init_root.
5026 * root.c: Added #include "genio.h", #include "smob.h", #include
5027 "pairs.h", #include "throw.h", #include "dynwind.h", #include
5029 (scm_init_root): Added #include "root.x".
5031 * throw.c: Added #include "stackchk.h"
5032 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
5033 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
5034 can be used in scm_call_with_new_root; Added reenabling of stack
5035 checking when catching a throw.
5037 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
5039 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
5041 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
5042 element is not found, as per R4RS.
5044 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
5046 * list.c: Doc fixes throughout.
5048 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
5050 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
5051 declare the char * to be const. Avoids a warning in rgx.c.
5053 * ports.h: spelling fix.
5055 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
5058 * load.c (scm_sys_try_load_path): throw an error if file not found
5059 (like it says it in NEWS).
5061 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
5063 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
5064 PROPS slot to '(), not #f; it's an empty alist.
5066 * throw.h, throw.c: Use SCM_P instead of #if hair.
5068 Remove special support for uncaught throws; see throw.c for
5070 * throw.c (uncaught_throw): New function.
5071 (scm_ithrow): Call uncaught_throw if we don't find a throw
5072 target; don't mess with scm_bad_throw_vcell.
5073 (scm_bad_throw_vcell): Variable deleted.
5074 (scm_init_throw): Don't initialize it.
5076 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
5079 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
5081 * numbers.c (scm_istr2int): If the number is short (as most
5082 numbers are), just call scm_small_istr2int to deal with it.
5083 (scm_small_istr2int): New function, created by un-#ifdefing the
5084 non-bignum version of scm_istr2int and renaming it.
5086 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
5088 * load.c (scm_sys_try_load): don't check whether value returned
5089 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
5090 Change the Scheme name from %try-load to primitive-load.
5092 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
5093 Can avoid passing a message, allowing it to be derived in the
5094 error handler (e.g., if we want to throw to the key both from
5097 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
5099 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
5100 references now have a new appearance which is more compact and
5101 also gives a clue about what the target of the reference is.
5102 By setting parameters in the print state, more fancy printing can
5103 be achieved. This is used by the (not yet commited) backtrace
5106 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
5108 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
5111 * print.c: Added #include "struct.h". Removed function
5114 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
5115 scm_iprin1. Removed prototype for scm_prlist.
5117 * arbiters.c (prinarb),
5118 async.c (print_async),
5119 debug.c (prindebugobj, prinmemoized),
5120 eval.c (prinprom, prinmacro),
5121 filesys.c (scm_fd_print, scm_dir_print),
5123 mallocs.c (prinmalloc),
5124 numbers.c, numbers.h (scm_floprint, scm_bigprint),
5125 smob.h (scm_smobfuns),
5126 srcprop.c (prinsrcprops),
5128 unif.c, unif.h (scm_raprin1, rapr1),
5129 variable.c (prin_var): Changed argument `int writing' to
5130 `scm_print_state *pstate'.
5132 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
5133 that it will be called before scm_init_print.
5135 * print.c (scm_prin1): Print states are now allocated when calling
5136 scm_prin1 and then passed around to all printing functions as an
5137 argument. A cache `print_state_pool' enables reuse of print
5139 (scm_make_print_state): New function.
5140 (scm_iprin1): Adaption to print states.
5141 (scm_iprlist): An initial "hare and tortoise" scan brings down
5142 time complexity to O (depth * N). (Better time complexity will be
5143 achieved when the printing code is completely rewritten.)
5145 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
5147 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
5148 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
5149 it gets done whether or not the cache variable has a value.
5151 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5153 Distinguish #f and ().
5154 * __scm.h: #undef SICP.
5155 * pairs.h (SCM_EOL): Delete this definition, equating it with
5157 * tags.h (SCM_EOL): Give it a new definition here; I think I found
5158 the value it used to have. Doc fixes, too.
5160 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
5162 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
5163 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
5164 Lord's implementation of structs, allowing for tail arrays as
5165 described in the manual. Also fixed some bugs. (Both the interface
5166 and the implementation should be improved.)
5168 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
5170 * print.c, print.h: Closures now print like #<procedure foo (x)>.
5171 People who whish to see the source can do `(print-enable 'source)'.
5172 Removed #ifdef DEBUG_EXTENSIONS.
5174 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5176 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
5177 integer (assuming for now accepting an integer is a good thing).
5179 * error.c, fports.c: replace use of %S in lgh_error args with %s.
5180 %S will be used instead for write'ing arguments.
5182 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
5183 asserts. fix a few other asserts.
5184 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
5185 scm_uniform_vector_ref, scm_array_set_x,
5186 scm_dimensions_to_unform_array): change args in
5187 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
5188 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
5189 scm_substring_fill_x): likewise.
5190 gsubr.c (scm_gsubr_apply): likewise.
5191 eval.c (SCM_APPLY): likewise.
5193 * eval.c (4 places): replace scm_everr with lgh_error or
5196 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
5197 scm_memory_error): new procedures.
5198 scm_everr: deleted. can use scm_wta, dropping first two args.
5199 scm_error: convert NULL subr to SCM_BOOL_F.
5201 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
5204 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
5207 * error.c, error.h: new error keys: scm_arg_type_key,
5208 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
5210 scm_wta: reimplement using lgh_error instead of scm_everr.
5212 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
5214 * gdbint.c: scm_lread now has one more argument.
5216 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
5217 scm_port_\1; Added mutator scm_set_port_filename_x (used when
5218 loading source from non-file ports, which, e. g., happens when
5219 using the Emacs interface).
5221 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
5224 * read.c: Added code for recording of positions of source code
5225 expressions; New functions: recsexpr, scm_lreadrecparen;
5226 _scm_make_srcprops --> scm_make_srcprops
5227 (scm_flush_ws): Removed updating of positions counters. This work
5228 is already done by scm_gen_getc
5230 * read.h: Added prototype for scm_lreadrecparen
5232 * print.c: Added #include "alist.h"
5234 * eval.c: Added #include "hash.h"
5236 * eq.c: Added #include "ramap.h"
5238 * options.c: Documentation fixes.
5240 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
5241 (scm_init_srcprop): Adjusted size of initial source-whash. Name
5242 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
5243 --> scm_make_srcprops
5245 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
5246 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
5247 function calls in the definition of the whash access macros.
5249 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
5251 * init.c (scm_boot_guile): Add level of indirection to
5252 scm_boot_guile_1() to ensure that stack base pointer is properly
5253 initialized. There was no guarantee that variable i was the
5254 highest/lowest variable on stack (i.e. the call frame of
5255 scm_boot_guile was not completely protected from gc).
5257 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
5259 * ports.h (scm_port_table): put back file_name, it will be used to
5260 support debugging. Undo related changes in fports.c, ioext.c,
5263 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5265 * ports.h (scm_port_table): remove file_name member for now, it seems
5267 * fports.c (scm_open_file): don't set file_name in PTAB.
5268 (prinfport): don't use file_name in PTAB.
5269 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
5270 * ports.c (scm_add_to_port_table): don't intialize file_name.
5271 (scm_port_file_name): remove for now.
5272 * gc.c (scm_gc_mark): don't mark PTAB file_name.
5274 * fports.h (scm_mkfile): prototype deleted.
5275 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
5277 * debug.c, unif.c: use scm_out_of_range instead of
5278 wta for range errors (ASSERT still needs work).
5280 * error.c, error.h (scm_out_of_range): new procedure.
5282 * error.c, error.h (scm_out_of_range_key): new key.
5284 * posix.c (scm_sync): #else was missing.
5286 * error.c, error.h: append _key to names scm_num_overflow and
5289 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
5290 of consing an empty list.
5291 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
5292 of macros, saves code and string space.
5293 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
5294 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
5295 lower case. Rename scm_syserror_m to scm_syserror_msg.
5296 error.h: prototypes for new procedures.
5298 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
5300 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
5302 * error.c, error.h: setup scm_num_overflow key.
5304 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
5305 Remove definition of SCM_OVSCM_FLOW.
5307 * fports.c (scm_open_file): use SCM_SYSERROR_M.
5309 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
5310 explicit message and args.
5312 * error.c, error.h, __scm.h: change system_error_sym to
5315 * error.c (system_error_sym): remove leading %% from the Scheme name
5318 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
5320 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5322 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
5323 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
5324 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
5325 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
5326 renamed. (These were introduced by unsupervised name
5329 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5331 * print.c: Added code for detection of circular references during
5332 printing. (init_ref_stack, grow_ref_stack): New functions. Added
5333 a hook for printing of closures (accessible via print options).
5334 This leads to a split of calls to scm_iprin1 into two classes:
5335 elementary print operations (e. g. the code which prints a smob)
5336 still use scm_iprin1 while top level calls (like scm_display) use
5337 scm_prin1. scm_prin1 begins by clearing the data structure used
5338 to record reference information.
5340 * print.h: Added declarations of scm_prin1 and scm_prlist.
5342 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
5344 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
5346 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
5348 * error.c (err_head): scm_iprin1 --> scm_prin1
5350 * debug.c: Adjusted header comment.
5354 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
5356 * strerror.c: Doc fix.
5358 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5360 * gdbint.c (gdb_read): Now possible to run during GC.
5361 (unmark_port, remark_port): New functions.
5363 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
5365 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
5366 of allocating a new string object. Also, increase size by
5367 the factor 2 instead of 1.5.
5369 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
5371 * __scm.h (SCM_P): Corrected to run under traditional C.
5373 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
5376 * async.c: Calls to scm_sysintern corrected.
5378 * async.h (scm_async_clock): Redundant declaration removed.
5380 * continuations.c (scm_dynthrow): Redundant declaration removed.
5382 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
5383 Definition typos corrected.
5385 * debug.h: Missing declarations of functions in debug.c added
5388 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
5389 Missing declarations to functions in eval.c added.
5391 * filesys.c: Possibly uninitialized variable rv.
5393 * gc.h (scm_object_addr, scm_unhash_name): Missing
5394 declarations of functions defined in gc.c added.
5396 * genio.c: Possible typos str_data -> wstr_data. ???
5398 * genio.c: Possibly unintended shadowing of local variable
5399 `int c' (gotos out of scope of inner `c'). ???
5401 * init.c: Uninitialized `SCM last' may be used.
5403 * ioext.h: (scm_sys_isatty_p): Typo.
5405 * list.h (scm_list_head): Missing prototype for function in
5408 * numbers.c (scm_two_doubles): Changed from extern to static
5409 (is used only within numbers.c).
5411 * numbers.h: Repeated declarations removed.
5413 * ports.h (scm_close_all_ports_except): Declaration for the
5414 function defined in ports.c added.
5416 * posix.h: Missing declarations added.
5418 * procs.h (scm_make_subr_opt): Missing declaration added.
5420 * socket.h (scm_sys_gethost): Missing declaration added.
5422 * socket.h: Redundant declarations removed (they are in fdsocket.h).
5424 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
5425 Missing declarations added.
5427 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
5429 * struct.c: Uninitialized variable `SCM answer' may be used.
5431 * unif.c (l2ra): Declaration prototype.
5433 * unif.c (scm_array_equal_p): Dummy definition removed (it is
5434 defined in ramap.c).
5436 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
5437 Redundant declarations removed (they are in ramap.h).
5439 * variable.h (scm_make_udvariable,
5440 scm_make_undefined_variable): Declaration corrected to
5441 correspond variable.c.
5443 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
5444 Missing declarations added.
5446 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5448 * Makefile.in (distclean): Don't forget to delete fd.h.
5450 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5452 * fd.h.in, tags.h: Trivial cleanups.
5454 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5455 marksweep.h just declared functions from gc.c.
5456 * gc.h, libguile.h: Don't #include "marksweep.h".
5457 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5458 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5459 dependencies updated.
5461 * libguile.h: Don't #include "files.h"; it's been deleted.
5463 * files.c (scm_sys_delete_file): Moved to filesys.c.
5464 File is now empty; deleted.
5466 * filesys.c: scm_sys_delete_file is now here. Remove
5467 #if's; they seem to rely on remnants of an old portability
5468 regimen. If the problems come up again, solve them properly,
5469 using autoconf. Specifically: Don't test M_SYSV, and #define
5470 remove to be unlink if it's #defined; don't use remove just
5471 because HAVE_STDC_HEADERS is #defined.
5472 * filesys.h: Add declarations for scm_sys_delete_file.
5473 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5474 files.o, files.h, files.c, and files.x.
5475 * init.c: Don't #include "files.h", and don't call scm_init_files.
5477 Use SCM_P instead of PROTO; the latter intrudes on the user's
5479 * params.h: Deleted; definition of SCM_P moved to...
5480 * __scm.h: ... here, where it replaces PROTO macro.
5481 * libguile.h, smob.h: Don't #include "params.h".
5482 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5483 smob.h: Fix prototypes accordingly.
5484 * Makefile.in: Update dependencies.
5485 (inner_h_files): Remove params.h.
5487 * gc.c: #include "gc.h"; every module should include its header,
5488 to let the compiler cross-check the declarations against the
5491 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5492 simpos.h: #include "libguile/__scm.h".
5494 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5496 * init.c: Don't forget to #include smob.h and init.h.
5497 * Makefile.in: Dependencies updated.
5499 * smob.h: Use PROTO instead of #if __STDC__.
5501 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5503 * __scm.h: Doc fixes.
5505 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5506 <angles>; this allows `make depends' to work properly.
5508 * libguile.h: #include smob.h and pairs.h before the others; they
5509 define typedefs used by other headers.
5511 C files should #include only the header files they need, not
5512 libguile.h (which #includes all the header files); the pointless
5513 recompilation was wasting my time.
5514 * Makefile.in (all .o dependency lists): Regenerated.
5515 * libguile.h: Don't try to get a definition for size_t here...
5516 * __scm.h: Do it here.
5517 * _scm.h: Since this is the internal libguile header, put things
5518 here that all (or a majority) of the libguile files will want.
5519 Don't #include <libguile.h> here; that generates dependencies on
5520 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5521 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5522 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5619 * weaks.c: Get "weaks.h".
5621 * stackchk.h: #include "libguile/debug.h",
5623 * print.h, read.h: #include "options.h", since everyone who uses
5624 either of these files will need that.
5626 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5627 anyone who uses this file will need them to define the smob
5628 printing functions. Also, get markers.h, since people will need
5629 to #define the mark functions.
5631 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5632 * ports.h: ... to here.
5634 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5635 don't rely on archaic C default type rules.
5637 * fports.h: #include "libguile/ports.h", since you need that in
5638 order to parse this.
5640 * genio.h: #include "libguile/print.h", because you need that to
5641 parse this; don't bother #including "ports.h", since print.h gets
5644 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5646 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5647 this; it's now a reference to an element of *scm_root.
5649 * debug.h: Don't #include "options.h"; the compiler won't be able
5650 to find that once the headers are installed; instead, #include
5651 "libguile/options.h".
5652 * gc.h: Same, with marksweep.h.
5653 * mbstrings.h: Same, with symbols.h.
5654 * scmhob.h: Same, with _scm.h.
5655 * smob.h: Same, with params.h.
5657 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5658 C files; there's no need for this, and it forces recompilations
5661 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5663 * error.c (scm_error): declare scm_error_callback.
5665 * error.h: prototype for scm_error_callback.
5667 * __scm.h: define lgh_error.
5668 (SCM_SYSERROR): redefine using lgh_error.
5670 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5672 * error.c (scm_error): new procedure.
5674 * error.h: prototype for scm_error.
5676 * Makefile.in (install): install scmconfig.h from the current
5677 directory, not $(srcdir).
5679 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5681 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5682 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5683 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

5689 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5690 vports.h, weaks.h: #include "libguile/__scm.h", not
5691 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5692 dependencies are within libguile properly.
5694 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5696 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5697 when scmconfig.h doesn't exist.
5699 * load.c (scm_sys_try_load): Correct spelling.
5701 * feature.c (scm_loc_features): Make this static.
5703 * Makefile.in (libpath.h): Omit trailing slash from path. We
5704 shouldn't require it of users, so why put it here?
5706 Move code to initialize and search %load-path from ice-9 to C
5707 code, so we can use the load-path to find the ice-9 boot code;
5708 this makes it easier to run Guile without installing it. See
5709 corresponding changes in guile/Makefile.in.
5710 * feature.c: Move stuff concerned with the load path to load.c.
5711 (scm_compiled_library_path): Deleted.
5712 Don't #include libpath.h here.
5713 * feature.h: Don't mention scm_compiled_library_path.
5714 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5715 <sys/stat.h>, and <unistd.h> (if present).
5716 (R_OK): #define if the system hasn't deigned to.
5717 (scm_loc_load_path): New variable.
5718 (scm_init_load_path, scm_sys_search_load_path,
5719 scm_sys_try_load_path): New functions.
5720 (scm_init_load): Initialize scm_loc_load_path to point to the
5721 value cell of the Scheme %load-path variable.
5722 * load.h: Add declarations for scm_sys_search_load_path,
5723 scm_sys_try_load_path.
5724 * init.c: Call scm_init_load_path.
5725 * Makefile.in (feature.o, load.o): Dependencies updated.
5727 * load.c, load.h: Rewrite using PROTO macro.
5729 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5731 * gc.c (scm_cellp): New function: C predicate to determine if an
5732 SCM value can be regarded as a pointer to a cell on the heap.
5734 * gc.h: Added declaration of scm_cellp.
5736 * gdb_interface.h: New file: The GDB interface header from the GDB
5739 * gdbint.c: New file: GDB interface.
5741 * gdbint.h: New file: GDB interface.
5743 * libguile.h: Added #include <libguile/gdbint.h>.
5745 * init.c (scm_boot_guile): Added scm_init_gdbint.
5747 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5748 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5749 found if object files and source are kept separate).
5751 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5753 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5755 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5757 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5758 TK_SRC_DIR; they're not relevant any more.
5760 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5761 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5763 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5765 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5766 search path, so we can find the <libguile/MUMBLE.h> headers.
5768 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5770 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5771 implicit in the .c.o rule.
5772 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5775 Put the library path in a header file, instead of passing it on
5776 the command line in every compilation.
5777 * Makefile.in (libpath.h): New target.
5778 (feature.o): Depend on libpath.h.
5779 (clean): Delete libpath.h.
5780 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5781 * feature.c: ... #include "libpath.h" here.
5782 * .cvsignore: Ignore libpath.h.
5784 Don't install the unwashed masses of Guile header files in the
5785 main #include path; put most of them in a subdirectory called
5786 'libguile'. This avoids naming conflicts between Guile header
5787 files and system header files (of which there were a few).
5788 * Makefile.in (pkgincludedir): Deleted.
5789 (innerincludedir): New variable; this and $(includedir) are enough.
5790 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5791 (installed_h_files): Divide this up. Now this variable lists
5792 those header files which should go into $(includedir) (i.e. appear
5793 directly in the #include path), and ...
5794 (inner_h_files): ... this new variable says which files appear in
5795 a subdirectory, and are referred to as <libguile/mumble.h>.
5796 (h_files): List them both.
5797 (install): Create innerincludedir, not pkgincludedir. Put
5798 the installed_h_files and inner_h_files in their proper places.
5799 (uninstall): Corresponding changes.
5800 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5801 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5802 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5803 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5804 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5805 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5806 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5807 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5808 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5809 vports.h, weaks.h: Find __scm.h in its new location.
5810 * __scm.h: Find scmconfig.h and tags.h in their new locations
5811 (they're both "inner" files).
5813 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5815 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5817 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5819 * posix.c: Doc fixes.
5821 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5823 * socket.c: Don't include a prototype for inet_aton; just use a
5824 K&R style declaration, to avoid warnings but minimize the chance
5825 of conflicts with the system.
5827 On NextStep, <utime.h> doesn't define struct utime, unless we
5828 #define _POSIX_SOURCE before #including it.
5829 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5830 * acconfig.h: New comment text for above CPP symbol.
5831 * configure.in: Call it.
5832 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5834 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5836 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5837 testing for __EMX__.
5839 * posix.c: #include <libc.h>, if it exists.
5841 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5842 don't even know if the latter exists.
5844 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5845 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5846 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5848 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5850 (scm_init_posix): Use them when initializing the Scheme constants
5853 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5855 * Makefile.in (libdir, includedir, bindir): Use the
5856 autoconf-supplied values, instead of deriving them ourselves.
5857 (pkgincludedir, datadir, pkgdatadir): New variables.
5858 (install, uninstall): Put the header files in a special
5859 subdirectory, not in the main search path.
5861 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5862 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5864 * Makefile.in (IMPLPATH): Deleted; never used.
5866 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5867 on the Tcl/Tk source any more.
5868 (INCLUDE_CFLAGS): Remove references to the above.
5870 * Makefile.in (version.o): Corrected dependencies.
5872 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5874 * libguile.h: #include "version.h"
5876 * init.c (scm_boot_guile): Call scm_init_version.
5877 * gscm.c (gscm_run_scm): Call scm_init_version.
5879 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5880 GUILE_VERSION): AC_DEFINE these.
5881 (acconfig.h): #undef the above symbols.
5883 * Makefile.in (libobjs): Add version.o.
5884 (installed_h_files): Add version.h.
5885 (c_files): Add version.c.
5886 (gen_c_files): Add version.x.
5887 (version.o): New rule.
5888 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5889 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
5890 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
5891 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
5892 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
5893 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
5894 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
5895 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
5896 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
5897 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5898 weaks.o): Add version.h to dependency lists.
5899 (markers.o): Remove duplicate rule.
5901 * version.h: New file.
5903 * version.c: New file.
5905 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5907 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5908 array; use it appropriately. Since GCC is quite happy to
5909 subscript functions, it never warned us about this; we should use
5910 -Wpointer-arith in the future. I guess we never tested
5913 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5915 * socket.c: Doc and copyright fixes.
5917 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5919 * debug.c: Fixed and improved gdb support.
5921 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5923 * socket.c: Added declaration of inet_aton to avoid compiler
5924 warning. (Hope this solution is correct.)
5926 * stime.c: Added declaration of ftime. (This is missing in
5929 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5931 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5933 * Makefile.in (c_files): add strerror.c.
5935 * strerror.c: new file from Emacs' sysdep.c.
5936 maybe configure should also check for sys_errlist.
5938 * configure.in (AC_REPLACE_FUNCS): add strerror.
5940 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5942 * debug.c (scm_init_debug): Added initialization for
5943 scm_evaluator_traps.
5945 * debug.h, debug.c: Various name changes.
5946 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5947 "debug-options-interface". See commentary in options.c.
5949 * options.h, options.c: Options now have documentation strings.
5950 Also added a long explanatory commentary.
5952 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5955 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5956 last_debug_info_frame is now updated in all cases.
5958 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5961 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5963 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5964 Added option STACK_CHECKING.
5966 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5968 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5970 * __scm.h: Removed symbols for debugging support.
5972 * acconfig.h: Added symbols for debugging support.
5974 * configure.in: Added user option for debugging support.
5975 --enable-debug will include the debugging code into libguile.a.
5977 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5978 scm_relocate_chunk_to_heap.
5980 * debug.c: New file: low-level debugging support. It also
5981 includes support for debugging with gdb. (The extensions to gdb
5982 are written by Per Bothner at Cygnus.)
5984 * debug.h: New file: low-level debugging support.
5986 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5987 argument pairs. Extensive modifications to the debugging
5988 evaluator. Added "SECTION:" commentaries to clarify what happens
5989 when, during double compilation. Renamed EVALIMP --> EVALIM.
5990 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5991 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5992 the beginning of the file. New procedure: scm_unmemocopy.
5993 Added some global state variables needed by the debugging
5994 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5995 check_entry, check_apply, check_exit, debug_options and
5996 evaluator_traps. New acro: undefine.
5998 * eval.h: Renamed EVAL --> XEVAL.
6000 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
6001 --> scm_make_weak_key_hash_table.
6003 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
6004 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
6006 * libguile.h: Conditionally include debug.h
6008 * objprop.c (scm_object_properties, scm_set_object_properties_x):
6009 scm_object_properties shouldn't return handle. `handle' now gets
6010 initialized in scm_set_object_properties_x. scm_object_properties
6011 doesn't any longer create an entry in scm_object_whash.
6013 * options.c: New file: handling of run time options.
6015 * options.h: New file: handling of run time options.
6017 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
6019 * print.c: New procedure: scm_print_options
6021 * print.h: Defines for print options.
6023 * read.c: New procedure: scm_read_options
6025 * read.h: Defines for reader options.
6027 * root.h: Added scm_source_whash among scm_sys_protects.
6029 * srcprop.c: New file: source properties.
6031 * srcprop.h: New file: source properties.
6033 * throw.c (jbsmob): Jump buffers are now correctly allocated.
6034 (Bug found by A. Green.)
6036 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
6038 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
6040 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
6042 * libguile.h: #include "objprop.h"; I guess this was forgotten.
6044 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
6045 and should be called by the final client.
6047 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
6049 * gc.h: Use the PROTO macro when declaring functions.
6050 * gc.c: Use the PROTO macro when declaring static functions.
6051 Remove the CPP hair around function definitions.
6053 * gc.c (scm_init_storage): Initialize scm_asyncs.
6055 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
6056 preprocessor symbol; "__scm.h" is where it might get #defined.
6057 * __scm.h: Similar: #include <scmconfig.h> before testing
6060 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
6062 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
6064 * init.c (scm_boot_guile): Add init_func argument; call
6065 (*init_func) instead of calling scm_appinit; it's ucky to
6066 hard-code names for the user's procedures.
6067 * init.h (scm_boot_guile): Adjust declaration.
6069 * __scm.h (PROTO): New macro, for declaring functions with
6072 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
6073 eliminate all the __STDC__ conditionals.
6074 (scm_boot_guile): Add declaration.
6075 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
6076 Remove __STDC__ conditionals around function definitions; the
6077 declarations in init.h will provide the same information, more
6080 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
6081 complain about it in the error message; the error message is
6082 adequate without that note, and there's nothing the user can do
6085 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
6087 * Makefile.in (ancillary): Drop def.sed.
6089 * posix.c (scm_init_posix): Use numeric values, rather than
6090 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
6091 F_OK. The symbols aren't available on some systems, and I'm
6092 pretty sure their values are fixed by common widespread practice.
6093 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
6095 More functions unavailable on some systems.
6096 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
6097 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
6099 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
6100 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
6101 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
6102 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
6103 stub that signals an error as the #else.
6105 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
6107 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
6109 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
6111 * unif.c: include ramap.h.
6113 * read.c (endif): case_insensative_p renamed case_insensitive_p.
6115 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
6117 * ports.c: include sys/ioctl.h.
6119 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
6121 * configure.in: check for sys/ioctl.h.
6123 * ports.c: include <malloc.h> not "malloc.h".
6125 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6127 * fports.c: remove ttyname and tmpnam declarations.
6129 * posix.c: fewer ttyname declarations.
6131 * fports.c: include <string.h> not "string.h".
6133 * init.c, ioext.c: include string.h and unistd.h.
6135 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6137 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
6138 genio.c, simpos.c, vports.c: include string.h.
6140 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
6142 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
6144 (scm_addr_buffer_size): change type from scm_sizet to int.
6145 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
6146 from scm_sizet to int.
6148 * error.c: include unistd.h.
6150 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
6153 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
6155 * __scm.hd, def.sed: deleted.
6157 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
6159 Changes for NeXT, suggested by Robert Brown.
6160 * configure.in: Call AC_TYPE_MODE_T.
6161 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
6162 NeXT. Put header file list in alphabetical order.
6163 * configure, scmconfig.h.in: Regenerated.
6164 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
6166 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
6169 * acconfig.h: New file, providing documentation for the CPP
6170 symbols defined in configure.in
6171 * acconfig-1.5.h: Removed; superceded by the above.
6173 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
6175 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
6177 * fports.c (scm_open_file): don't return #f, throw error.
6179 * ioext.c (fileno): renamed from %fileno.
6180 (soft-fileno): deleted.
6182 * ports.c (scm_port_revealed): don't need to check for -1 from
6184 (scm_set_port_revealed_x): return unspecified, not #f.
6186 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
6188 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
6190 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
6192 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
6194 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
6196 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
6197 This is necessary on Ultrix, and doesn't hurt portability.
6199 * Makefile.in (dist-dir): New target, implementing a new dist system.
6200 (installed_h_files): Put in alphabetical order.
6201 Remove duplicate entries for markers.h and unif.h.
6202 (c_files): Remove duplicate entries for markers.c.
6203 (ancillary): Renamed from anillery; all uses changed. Remove
6204 PLUGIN; it's a directory, and needs special treatment in dist-dir.
6205 Remove all the ../doc/* files; doc/Makefile.in handles that.
6207 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
6209 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
6210 every if must have an else, or else the whole command has a
6211 non-zero exit code whenever the if's condition is false.
6213 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
6215 * posix.c: include string.h.
6217 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
6219 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
6222 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
6223 Remove leading % from scheme names.
6224 Do not return error values, call SCM_SYSERROR or similar.
6226 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
6228 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
6230 * struct.c (scm_init_struct): new file.
6232 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
6234 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
6235 (scm_list_head): added list-head for rapidly chopping argument
6236 lists off of longer lists (and similar).
6238 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
6240 * objprop.c (scm_object_property): assq the cdr of the whash
6241 handle for obj, not the handle itself.
6243 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
6245 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
6246 weak hash tables last of all marking to avoid an obscure gc bug.

6300 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
6301 handled correctly (SCM_FREEP was applied to them) -- test for

6470 initialization to fix a race condition.
6472 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

6496 set the multi_byte flag correctly in symbols. This is wrong.
6497 intern_obbary_soft and msymbolize should take an extra parameter.
6498 Also, weird multibyte symbols don't print correctly.
6499 The weird symbol syntax is also a bit bogus (emacs doesn't quite
