1 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3 * objects.c (scm_i_make_class_object): Renamed from
4 make_class_object; exported; error checking moved to
5 scm_make_class_object and scm_make_subclass_object.
6 (scm_make_class_object, scm_make_subclass_object): Use
7 scm_i_make_class_object.
8 (scm_make_subclass_object): Let the subclass have same metaclass
11 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
13 * debug.c (scm_debug_options): Bugfix: Set the value of
14 scm_stack_checking_enabled_p after setting debug options;
15 #include "stackchk.h". (Thanks to Richard Polton.)
17 1998-11-13 Radey Shouman <rshouman@metro2000.com>
19 * unif.c (scm_array_contents): removed unnecessary test for 0
22 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
24 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
25 Replaced by macro `collect' in boot-9.scm.
27 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
29 * eval.c (scm_copy_tree): Copy source properties if existent.
31 * debug.c (scm_start_stack): Copy source when evaluating. (If we
32 don't, we may end up passing memoized source to a transformer.)
34 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
36 * stack.c (get_applybody): Help function which lookups the first
37 body form of the apply closure.
38 (read_frames): Prevent the source of the first form of the apply
39 closure from being recorded. This would only be confusing.
41 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
42 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
44 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
46 * stacks.c (read_frame): Bugfix: Removed lingering `else'
48 (read_frames): Use SCM_MACROEXPP.
50 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
52 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
53 don't contain interesting information since all arguments are
54 present in the frame which applies the compiled closure anyway.);
55 Skip the transformer application frames.
57 * print.c (scm_iprin1): Print gsubrs as primitives.
59 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
61 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
63 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
64 that we can identify these in a backtrace. (This change doesn't
65 introduce any significant speed penalty.)
67 * eval.c: Added note about `serial-map' using scm_map.
69 * read.c, read.h (scm_read_options, scm_read_opts): Removed
70 readline options. They should reside in their own options array.
72 * readline.c, readline.h (scm_readline_options,
73 scm_readline_opts): Moved readline options here.
75 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
77 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
78 SCM_ROCHARS instead of SCM_CHARS.
80 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
81 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
83 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
85 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
86 This is quite important since the latter clears the
87 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
88 every single character read...
90 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
92 * print.c (scm_iprin1): Removed suspect looking (and indeed
93 malevolent) semicolon after test for user supplied closure print
94 procedure. (Thanks to Telford Tendys.)
96 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
97 (scm_memq, scm_memv, scm_member): Do argument checking *before*
98 starting to search the list. Removed call to sloppy_mem_check.
100 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
101 procedures: Same as scm_delq_x et al, but delete maximally one
104 * options.c (scm_options, scm_init_options): GC-protect option
105 values of type SCM. (Thanks to Telford Tendys.)
107 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
109 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
110 make sure that there always is a "real" scm_lookupcar.
112 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
114 * read.c, read.h (history-length, history-file): New read options.
115 (scm_read_options): Stifle history to history length.
117 * readline.c (scm_read_history, scm_write_history): New
120 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
122 * eval.h (scm_macro_eval_x): Removed declaration.
124 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
125 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
126 Renamed and made global.
128 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
129 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
131 * evalext.c, evalext.h: New files. Contain non-R5RS things
132 having to do with evaluation.
134 * evalext.c (scm_serial_map): New procedure: Version of `map'
135 which guarantees that the procedure is applied to the lists in
137 (scm_m_sequence_to_list): New syntax: Version of `begin' which
138 returns a list of the results of the body forms instead of the
139 result of the last body form.
140 (scm_definedp, scm_m_undefine): Moved from eval.c
142 * evalext.h (scm_m_sequence_to_list): Added declaration.
144 * macros.c, macros.h: New files.
145 (scm_procedure_to_syntax, scm_procedure_to_macro,
146 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
147 scm_macro_name, scm_macro_transformer): Moved from eval.c
148 (scm_make_synt): Moved from eval.c
150 * procs.c, procs.h (scm_procedure_documentation): Moved from
153 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
156 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
158 * debug.c, print.c: Added #include "macros.h".
160 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
162 This change adds the ability to use `unread-char' multiple times
163 without interspersed reads and adds the new procedure
164 `unread-string'. The change is optimized for the common case of
165 unreading a single character. This is also the reason behind the
166 choice to store characters in the port itself: in most cases no
167 extra malloc is required.
169 The amount of code in some macros in ports.h has been increased to
170 the extent that they would fit better as C functions, but, since
171 this code belongs to the port representation, such functions
172 should be placed in ports.c which would cause calls back and forth
173 between ports.c and genio.c. That is not good for performance.
174 Also, keeping them as macros allows the compiler to do some
175 optimizations which are needed to make the current interface
176 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
178 One benchmark (Guile startup time) indicates an increase of
179 loading speed of 1%. Another (reading (using `read') boot-9.scm
180 10 times) shows no change in performance.
182 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
183 made to find a beautiful solution.)
185 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
186 (SCM_TRY_CLRDY): New macro: Only clear the first unread
187 character. (SCM_CLRDY clears all.)
188 (SCM_N_READY_CHARS): New macro: Returns number of unread
189 characters in a port. Returns wrong answer if SCM_CRDYP is false.
190 (struct scm_port_table): New fields: `entry' contains port table
191 index, `cp' points to last unread char, `cbuf' is the buffer for
192 unread chars, `cbufend' points after end of the character buffer.
194 * ports.h, ports.c (scm_unread_string): New procedure.
195 (scm_grow_port_cbuf): New function.
197 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
199 (scm_generic_fgets), fports.c (local_fgets): Use a loop
200 to read unread characters. Use SCM_TRY_CLRDY instead of
203 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
205 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
207 * genio.c, genio.h (scm_ungets): New function.
209 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
212 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
214 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
215 declarations. (Thanks to Russ McManus.)
217 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
219 * numbers.c (num2long): As a software archeologist, I'm proud of
220 this finding! :) Preliminary dating suggests an almost 4 year old
221 remnant from the SCM ancestor. The sample has been removed from
222 the finding site and is now safely stored in the repository.
224 * numbers.h: Removed prototype for num2long.
226 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
228 * gh_data.c (gh_scm2doubles): Make it possible to pass result
230 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
231 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
232 * gh.h: Updated and added prototypes.
234 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
236 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
238 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
240 * guile-snarf.in: Never generate an empty file. (Thanks to
243 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
244 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
245 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
246 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
247 gh_new_procedure5_0): Specify argument types, to appease C++
248 compilers. (Thanks to Brad Bowman.)
250 Bug reports from Russ McManus:
251 * guile-snarf.in: If the CPP environment variable is set, use that
252 as the C preprocessor, instead of the preprocessor autoconf
254 * snarf.h (SCM_PROC): Cast the function pointer passed to
255 scm_make_gsubr, to satisfy C++.
257 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
258 Use the handler passed, instead of ignoring it and using
259 gh_standard_handler. (Thanks to Etienne Bernard.)
261 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
263 * ports.h: Put text after #endif in comment. (Thanks to Nicolas

286 * script.c (scm_compile_shell_switches): Define
287 use-emacs-interface in the root module, so the repl code can see
288 it. See today's change to top-repl in ice-9/boot-9.scm.
290 * filesys.c (set_element, get_element): Make sure that `element'
291 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
292 Boekemeier and Jorgen "forcer" Schaefer.)
294 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
296 * chars.c (scm_charnames): In ASCII character name table, make
297 newlines print as #\newline by default, not #\nl.
299 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
300 alphabetical order. Oh thrills. But it helps me know how far
301 along in the compilation I am.
302 * Makefile.in: Regenerated.
304 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
306 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
307 #bytes(...) to #y(...), and syntax for short vectors from
308 #short(...) to #h(...). This may seem nutty, but, like the other
309 uniform vectors, byte vectors and short vectors want to have the
310 same print and read syntax (and, more basic, want to have read
311 syntax!). Changing the read syntax to use multiple characters
312 after the hash sign breaks with the conventions used in R5RS and
313 the conventions used for the other uniform vectors. It also
314 introduces complexity in the current reader, both on the C and
315 Scheme levels. (The Right solution is probably to change the
316 syntax and prototypes for uniform vectors entirely.)
318 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
320 Don't use local_fgets on sockets; ftell doesn't work on sockets.
321 (Thanks to Jorgen "forcer" Schaefer.)
322 * ports.h (SCM_NOFTELL): New flag.
323 * fports.c (local_fgets): If it's set, use the generic fgets.
324 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
326 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
328 * script.c (scm_compile_shell_switches): Add handling of -q switch
329 (inhibit loading of user init file).
330 (scm_shell_usage): Add usage text for -q switch.
331 (scm_compile_shell_switches): Always load user init file first if
334 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
336 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
337 and is now broken under NetBSD. I can't fathom what it's trying
338 to do, so I've replaced it with something that I do understand,
339 which seems to work, and which isn't broken on NetBSD. "Progress?
340 You Decide." (Thanks to Perry Metzger.)
342 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
343 signed/unsigned comparison.
345 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
347 Warning fixes from Greg Harvey:
348 * unif.c (scm_array_set_x): initializer for pos
349 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
350 * struct.c (scm_struct_ref, scm_struct_set_x): Added
351 initializers for field_type, since EGCS so desparately wants to
353 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
354 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
355 when GUILE_DEBUG is defined.
356 * dynwind.h (scm_wind_chain): Same.
357 * ports.h (scm_pt_size, scm_pt_member): Same.
358 * print.h (scm_current_pstate): Same.
359 * procs.h (scm_make_cclo): Same.
361 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
363 Handle short and long long uniform arrays properly. (Thanks to
365 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
366 raeql_1): Add cases for scm_tc7_svect (short vectors) and
367 scm_tc7_llvect (long long vectors).
369 Change the way libguile and boot-9.scm are timestamped, to try to
370 get rid of these spurious mismatch warnings. Now both
371 libguile/versiondat.h and ice-9/version.scm are generated directly
372 by the configuration process, rather than having version.scm
373 generated directly, and libguile/versiondat.h generated by the
374 Makefile, which is generated by configure. It seems that
375 sometimes the Makefile would change, but versiondat.h depends on
376 Makefile.in, not Makefile, so it wouldn't get rebuilt.
377 * Makefile.am (versiondat.h): Target removed; this is generated
378 directly by the configure script now.
379 (BUILT_SOURCES): Remove versiondat.h.
380 * versiondat.h.in: New file, transformed by the configure script
382 * Makefile.in: Regenerated.
384 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
385 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
386 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
387 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
388 if we want to use them in a header file some day, we can. (Thanks
391 * stime.c (scm_get_internal_real_time): Do the arithmetic using
392 SCM numbers, so we won't have rollover problems; the range of a
393 signed long in milliseconds is about 25 days. (Thanks to Karl
396 Don't redefine sleep and usleep; fix this problem now.
397 * coop.c (sleep, usleep): Remove declarations; we don't use or
398 redefine these any more.
399 (scm_thread_usleep, scm_thread_sleep): New functions which do the
400 job of usleep and sleep in a thread-friendly way. We can use
401 these in the rest of Guile. Define versions for systems both with
403 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
404 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
405 we're just using it, not redefining it, we can use a K&R style
407 (sleep): Declare this, too, if the system hasn't.
408 (scm_sleep, scm_usleep): Use scm_thread_sleep and
409 scm_uthread_sleep if they're available; otherwise, just call the
411 * scmconfig.h.in: Regenerated.
413 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
415 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
417 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
419 * threads.c: Doc fix.
421 The argument type of usleep varies from system to system,
422 as does the return type. We really shouldn't be redefining usleep
423 at all, but I don't have time to clean that up before the 1.3.
424 release. It's on the schedule for afterwards. (Thanks to Julian
426 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
428 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
429 * scmconfig.h: Regenerated.
431 * simpos.c (scm_software_type): Procedure deleted. This isn't the
432 right way to handle system variation. Autoconf's approach is the
434 * simpos.h (scm_software_type): Declaration deleted.
436 * script.c (scm_find_executable): Don't test if unix is #defined
437 here; first, NetBSD doesn't #define it, and second, it's the wrong
438 way to go about these things. (Thanks to Perry Metzger.)
439 (dld_find_executable): Delete this MSDOS support code. This isn't
440 the way we want to support this; it needs to be rethunk at a
443 * genio.c (scm_do_read_line): Don't just politely check that the
444 line was either non-empty or EOF. Abort if it's empty and not
447 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
449 * scmconfig.h.in: Regenerated.
451 * libguile.h: Don't omit the dynamic linking functions. (Thanks
454 * genio.c (scm_do_read_line): Count lines correctly when the file
455 doesn't end in a newline.
457 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
459 * genio.c (scm_do_read_line): Maintain the line count correctly.
460 (Thanks to Harvey J. Stein and Greg Harvey.)
462 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
465 * numbers.c (big2str): Protect t from garbage collection until
466 we're done. (Thanks to Gary Houston.)
468 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
470 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
472 * Makefile.in: Regenerated.
474 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
475 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
478 Do magic to mix reads and writes on stdio FILE-based ports.
479 (Thanks to Christian Lynbech.)
480 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
482 (pre_read, pre_write): New functions.
483 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
484 local_fputs): Call them.
485 (local_fflush): Mark the port as ready for reading and writing.
486 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
487 flags on new port objects. This might not be accurate --- who
488 knows what state the FILE * is in when we get it --- but it won't
489 do extraneous calls to fflush or fseek, so it's no worse than the
490 behavior before this change.
491 * ports.h: Add comment.
493 Centralize the creation of port objects based on stdio FILE * in
494 fports.c; don't just throw them together anywhere.
495 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
496 what the rest of Guile wants. Don't set the revealed count;
497 that's only appropriate for stdin, stdout, stderr.
498 (scm_standard_stream_to_port): This function does set the revealed
500 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
501 not scm_stdio_to_port.
502 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
503 * fports.c (scm_open_file): Same.
504 * posix.c (scm_pipe): Same.
505 * socket.c (scm_sock_fd_to_port): Same.
506 * ioext.c (scm_fdopen): Same.
507 (scm_freopen): Moved from here to...
508 * fports.c (scm_freopen): ... here. This is really something that
509 munges the internals of an fport, so it should go here.
510 * fports.h (scm_stdio_to_port): Adjust prototype.
511 (scm_standard_stream_to_port, scm_freopen): New protoypes.
512 * ioext.h (scm_freopen): Prototype removed.
514 * filesys.c (set_element, get_element): This can work on both pipe
515 and file ports, so use SCM_FPORTP to typecheck, instead of testing
518 * scmconfig.h.in: Regenerated.
520 Change the definition of the functions in scm_ptobfuns so that
521 they get passed the port object, not the port's stream.
522 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
523 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
524 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
525 Pass the port itself to the scm_ptobs function.
526 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
527 scm_generic_fgets): Same.
528 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
529 getc_void_port, fgets_void_port, close_void_port): Just change the
530 argument names; these functions don't really do anything.
531 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
532 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
533 port as an argument, and use SCM_STREAM to get the stdio FILE *.
534 Also, use prototyped definitions, and get rid of the extra
536 (scm_fptob, scm_pipob): We don't need casts here any more.
537 * strports.c (prinstpt): Use prototype declarations.
538 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
539 and use SCM_STREAM to get the string info. Also, use prototyped
540 definitions, and get rid of the extra declarations.
541 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
544 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
545 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
547 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
548 scm_fgets, for consistency.
549 (scm_fptop, scm_pipob): References updated.
551 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
553 Include the source location in error messages for scripts.
554 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
555 stack is still there when we catch the error.
556 * throw.c (handler_message): If we are handling an error with a
557 message, then put together the proper arguments and call
558 scm_display_error, instead of scm_display_error_message. That
559 displays source location, if it can find it.
561 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
563 * gc.c (scm_unprotect_object): Change this so that calls to
564 scm_protect_object and scm_unprotect_object nest properly.
565 (scm_protect_object): Doc fixes.
567 * strings.c (scm_string_set_x): Require the argument to be a
568 writable string, not a substring or a symbol.
569 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
570 (Thanks to John Redford and Charbel Jacquin.)
572 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
574 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
576 * eval.c (safe_setjmp): Remove this misunderstanding.
577 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
580 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
582 * libguile.h: Mark these as C declarations, for compilation by C++
585 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
586 __cplusplus clause. I seriously doubt this ever worked the way
587 the author seems to have intended.
589 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
591 Utterly needless cleanups to hopelessly messy code.
592 * ports.c: Doc fixes.
593 (scm_fflush): Moved to ...
594 * genio.c (scm_fflush): ... here, amongst all the other port
595 method invocation functions.
596 * genio.h, ports.h: The prototype moves too.
598 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
600 * backtrace.c (display_error_body): The current frame does not
601 always have a parent frame; consider a function called directly
602 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
605 * alloca.c (alloca): Undo yesterday's changes, and simply call
606 malloc directly for storage, and abort if we don't get what we
607 want. The situation is much simpler --- just call malloc. Emacs
608 has bizarre/evil requirements (signal handlers might malloc unless
609 you set this global flag, so you have to set the flag around all
610 calls to malloc) which we are certainly not going to conform to,
611 so we can do the simple and obvious thing.
613 * coop.c (coop_condition_variable_wait): Make this function
614 static. It's only useful internally --- you should never just
615 wait on a condition variable.
616 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
618 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
620 * unif.c (scm_array_set_x): Accept any kind of number as an
621 element for a uniform vector of doubles. This is more consistent
622 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
624 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
625 works; I can't conveniently test it myself. (Thanks to Dvid
626 Tillman for the bug report.)
630 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
631 from here, not from scm_compile_shell_switches (which is a pretty
632 dumb place to do it).
633 (scm_load_startup_files): New function.
634 (scm_ice_9_already_loaded): Variable moved to here from script.c.
635 * script.c (scm_compile_shell_switches): Don't load the startup
637 (scm_ice_9_already_loaded): Variable moved.
638 * init.c (scm_load_startup_files): Prototype for new function.
639 * gh_init.c (gh_enter): Doc fix.
641 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
643 Some anti-warning changes from Greg Harvey.
644 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
645 warnings when it doesn't understand our NORETURN declarations in
647 * posix.c (scm_mknod): Similar.
649 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
651 * posix.c (scm_getpwuid): If we can't find an entry, return our
652 own message, instead of using scm_syserror --- the getpwMUMBLE
653 functions don't set `errno' to anything interesting.
655 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
657 Get rid of warnings from the cooperative threading system.
658 * threads.h (scm_single_thread_p, scm_yield,
659 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
660 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
661 scm_wait_condition_variable, scm_signal_condition_variable): Add
662 prototypes for these Scheme-visible functions.
663 * coop-defs.h (coop_next_runnable_thread,
664 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
665 Prototypes for these here, even though they're from iselect.c.
666 (coop_condition_variable_wait, coop_join): Add prototypes.
667 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
668 scm_threads_free_condvar): Make these smob functions static.
669 * coop-threads.h (coop_init): Give this a real prototype.
670 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
671 (coop_next_runnable_thread): No need to provide prototype; it's in
674 * scmconfig.h.in: .detarenegeR
676 * iselect.c, threads.c: Doc fixes.
678 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
680 * Makefile.in: Regenerated with a patched automake, to get
681 dependency generation right when using EGCS.
683 * inet_aton.c (inet_aton): Add prototype, to remove compiler
684 warning. (Thanks to Robert Pluim.)
686 * inet_aton.c (inet_aton): Reassure the compiler that the
687 arguments to the <ctype.h> macros are all unsigned characters, not
690 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
692 Getting rid of more warnings...
693 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
694 today's change to ../configure.in.
695 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
696 * scmconfig.h.in: Regenertaded.de.,.__
697 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
698 (scm_localtime, scm_mktime): Use a const char * to manipulate the
701 * readline.c: Doc fix.
702 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
703 * readline.h (scm_filename_completion_function): Add prototype.
704 (scm_init_readline): Make this into a prototype.
706 * readline.c (scm_filename_completion_function): Use SCM_PROC to
707 declare this, instead of calling scm_make_subr manually.
709 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
711 * readline.h (scm_init_readline): Add prototype for this.
712 (scm_init_readline): Make this a real prototype.
714 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
716 Warning fixes from Maciej Stachowiak:
717 * backtrace.h (scm_display_application, scm_backtrace): Add
719 * debug.c (scm_m_start_stack): Make this function static.
720 * fluids.h (scm_fluid_p): Add prototype.
721 * procprop.c (scm_i_procedure_arity): Make this function static.
722 * regex-posix.c (scm_regexp_error_msg): Make this function static.
723 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
724 * root.h (scm_dynamic_root): Add external prototype.
725 * scmsigs.h (scm_usleep): Add external prototype.
726 * script.h (scm_init_script): Use prototype, not K&R decl.
727 * stacks.h (scm_stack_id): Add external prototype.
728 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
730 1998-09-30 Mark Galassi <rosalia@cygnus.com>
732 * gh.h: took out the definitions of vset and vref, since they are
733 replaced by the proper vector routines that correspond to the R4RS
736 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
738 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
739 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
740 third argument, a C expression that should result in a SCM value,
741 which is used to initialize the variable. Reimplemented
742 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
745 * version.h (scm_libguile_config_stamp): Add prototype.
746 (From Maciej Stachowiak.)
748 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
750 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
751 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
753 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
755 * print.c (scm_iprin1): Rather than having one i, and using it in
756 several places, declare a fresh i local to each block where it is
757 used, and give it a signedness appropriate to its use in each case.
760 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
763 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
764 signed/unsigned clashes.
766 * posix.h (scm_tmpnam): Added prototype.
768 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
769 scm_make_subclass_object): Add external prototypes.
771 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
772 comparison is okay here.
774 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
776 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
777 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
779 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
782 * load.c (swap_port): Make this function static.
784 * load.c (scm_search_path): Make max_path_len and max_ext_len
785 unsigned, since they're compared against string sizes.
787 * load.c (init_build_info): Make i unsigned.
789 * ioext.h (scm_read_line): Add prototype.
791 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
792 scm_hash_fn_remove_x): Make hash bucket index local variable k
793 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
794 accurately as possible.
796 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
797 comparisons, and range checking to make sure those casts are
800 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
801 signed/unsigned comparisons.
803 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
804 avoid signed/unsigned comparisons.
805 * smob.h (scm_numsmob): Change extern declaration to match.
807 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
808 avoid signed/unsigned comparisons.
809 * ports.h (scm_numptob): Change extern declaration to match.
810 (scm_current_load_port, scm_set_port_line_x,
811 scm_set_port_column_x): New prototypes.
813 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
814 test code, and it causes warnings.
816 * gh.h (gh_int2scmb, gh_uniform_vector_length,
817 gh_uniform_vector_ref): Added prototypes.
819 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
820 debugging support unconditionally. That's backtrace.c, stack.c,
821 debug.c, and srcprop.c.
822 (EXTRA_libguile_la_SOURCES): Omit those from here.
823 * Makefile.in: Regenerated.
825 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
827 * options.c (scm_options): Bugfix: Allow empty list of options!
829 * debug.c, debug.h (scm_single_step): Removed.
830 (scm_with_traps): New procedure. This procedure could easily be
831 written in Scheme but needs to be highly optimized.
833 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
835 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
836 Check SCM_TRAPS_P before trapping.
838 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
840 Changes to avoid signed/unsigned comparison warnings.
841 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
842 (scm_gc_sweep): Make n and j local to the blocks they're used in,
843 so they can have appropriate types for each application. Make i
844 signed. Use initializers in some spots. I'll probably pay for
846 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
847 (scm_must_realloc): Make nm unsigned.
848 (init_heap_seg): Make new_seg_index and n_new_objects signed.
849 (scm_init_storage): Use prototype-style definition, and make the
851 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
852 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
854 * filesys.c (scm_readlink): Make local vars rv and size ints, to
855 avoid signed/unsigned comparison warnings, and because the return
856 value of readlink may be -1. Don't bother casting the third
857 argument to readlink.
859 * filesys.c (scm_dirname, scm_basename): Move these to their own
860 page, at the end of the file.
861 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
863 * eval.h (scm_eval_options_interface): Add external prototype for this.
864 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
866 * eval.c (scm_lookupcar1): Make this static.
868 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
869 Make these prototype declarations, not K&R-style.
871 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
872 unsigned comparison warning.
874 * appinit.c: File removed. It had a single function in it, empty,
875 whose reason for existence is explained in no documentation or
876 comment. I think it's there as a default for some Tcl-style
877 initialization, but Tcl abandoned that approach a while ago.
878 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
879 (BUILT_SOURCES): Remove appinit.x.
880 * Makefile.in: Regenerated.
882 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
884 * Makefile.in: Regenerated using the last public version of
885 automake, not the hacked Cygnus version.
887 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
889 Remove Totoro kludge.
890 * Makefile.in, scmconfig.h.in: Regenerated.
891 * init.c, readline.c: Don't check if TOTORO is #defined.
893 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
895 * Makefile.am: Adjust for new thread configuration system.
896 (INCLUDES): Include the value of THREAD_CPPFLAGS.
897 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
899 (THREAD_LIBS): Definition deleted; automake will generate such
900 things automatically.
901 * Makefile.in: Regenerated.
903 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
905 Simplify smob and port marking; set the mark bit in the generic
906 marking code, and make marker routines only responsible for
907 turning up outgoing pointers.
908 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
909 before calling the marking function. Don't call the marking
910 function if it's zero.
911 * markers.c (scm_mark0): Just return #f. This function isn't
912 necessary at all now, but it's harmless to call it. We'll leave
913 it in so other folks' code doesn't croak at link time.
914 (scm_markcdr): Don't call SCM_SETGC8MARK.
915 * async.c (mark_async): Don't call SCM_SETGC8MARK.
916 * dynl.c (mark_dynl_obj): Same.
917 * root.c (mark_root): Same.
918 * srcprop.c (marksrcprops): Same.
919 * unif.c (markra): Same.
920 * variable.c (scm_markvar): Same.
921 * ports.c (scm_markstream): Same.
922 (void_port_ptob): Specify zero for our marking function.
923 * debug.c (debugobjsmob): Same.
924 * dynwind.c (guardsmob): Same.
925 * filesys.c (dir_smob): Same.
926 * fluids.c (fluid_smob): Same.
927 * fports.c (scm_fptob, scm_pipob): Same.
928 * mallocs.c (mallocsmob): Same.
929 * regex-posix.c (regex_t_smob): Same.
930 * smob.c (freecell, flob, bigob): Same.
931 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
932 * throw.c (jbsmob, lazy_catch_funs): Same.
934 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
936 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
937 scm_copy_tree on code in order not to let memoized code to leak
938 out. Thus, scm_copy_tree needs to copy vectors as well since
939 quasiquote can introduce evaluated code also inside vector
942 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
944 * eval.c (scm_copy_tree): Removed ability to copy vectors.
946 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
947 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
950 * unif.c: Say that ivect and uvect are of type signed and unsigned
951 long instead of int in commentary so that it correctly describes
954 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
956 * stime.c: Removed declaration of strptime. (It should be
957 declared by the system headers. If it turns out that some systems
958 don't, we'll handle that then.) (Thanks to Greg Troxel.)
960 * stime.h: Renamed TIMEH --> STIMEH
962 * backtrace.c (scm_display_error, scm_display_backtrace): In order
963 to increase portability, don't use structure assignment.
964 (Thanks to Nicolas Neuss.)
966 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
968 (finalize_fd_sets): Added empty statement after last case label.
969 (Thanks to Nicolas Neuss.)
971 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
974 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
976 * init.c, readline.c: OK, I won't have these readline.x bug
977 reports anymore. We've had them since April. The current reason
978 is a completely unintelligible failure of totoro.red-bean.com to
979 do the test for rl_getc_function in libreadline correctly. This
980 kludge overrides the test if we're on totoro so that the snapshot
981 generation process can work.
983 * readline.c: Define a strdup replacement if not existent on system.
985 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
987 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
988 This change makes scm_make_vector R5RS compatible. We cannot keep
989 the third argument since people want to be able to deduce the form
990 of the C function call only by looking at R5RS. (At the same time
991 we have removed some unnecessary complexity!)
993 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
994 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
995 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
996 argument in call to scm_make_vector.
998 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1000 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
1001 This macro is useful in applications.
1003 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1005 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
1006 (scm_parse_path, scm_search_path): New Scheme level procedures.
1008 * load.h (scm_internal_parse_path, scm_parse_path,
1009 scm_search_path): Declared.
1011 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1013 * filesys.c (dirname, basename): New procedures.
1015 * init.c (scm_boot_guile_1): Removed condition around
1018 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
1019 new data type (guards) for representation of C level guards and
1020 data on the wind chain.
1021 (scm_internal_dynamic_wind): New function.
1023 * dynwind.h: Declare scm_internal_dynamic_wind.
1025 * root.h (scm_root_state): Added scm_cur_loadp.
1027 * root.c (mark_root): Added comment about cur_loadp.
1029 * load.c: #include "dynwind.h";

1033 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
1035 * ports.c (current-load-port): New procedure.
1037 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1039 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
1040 not a tty, return #f.
1042 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
1043 to Julian Satchell and Roland Kaufmann.)
1045 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
1046 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
1048 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1050 * debug.h, debug.c (scm_start_stack): New function. Implements
1051 the guts of old scm_m_start_stack.
1053 * debug.c (scm_m_start_stack): Use scm_start_stack.
1055 * init.c (scm_start_stack, scm_restart_stack): Renamed to
1056 start_stack and restart_stack. (These have static scope.)
1058 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1060 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
1061 readline functions to come in release 2.3. (Thanks to Chet
1063 (handle_errors): Use the above functions.
1065 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1067 * readline.c: Improvements for readline support: Handle errors
1068 better; Implement before-read-hook.
1070 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1072 * init.c (scm_boot_guile_1), readline.c: Test for
1073 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
1074 assure that we have version >= 2.1.)
1076 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
1078 * readline.c (scm_readline): Defer interrupts while we're calling
1081 * readline.c (scm_add_history): Bugfix: Do strdup before giving
1082 away the string to add_history.
1083 (completion_function): Do completion for readline. (Thanks to
1085 (scm_filename_completion_function): New procedure: Filename
1087 (current_input_getc): New function. Use this one instead of
1088 standard getc from readline.
1090 * throw.c, throw.h (scm_handle_by_throw): New function: This
1091 handler throws errors to next handler on the dynwind chain.
1093 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
1095 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
1098 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1100 * procprop.c (scm_i_procedure_arity): New function. Returns arity
1102 (scm_procedure_properties): Modified to return arity together with
1104 (scm_procedure_property): Added the read-only property `arity'.
1105 (scm_set_procedure_property_x): It is an error to set the `arity'
1108 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
1109 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
1111 * procprop.h (scm_sym_arity): New symbol.
1113 * objects.c (scm_set_object_procedure_x): New procedure: Use this
1114 to set the dispatch procedure of an operator or entity object.
1116 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
1117 Made procedure slots read-only.
1119 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
1120 scm_tcs_cons_gloc case in zero args switch; Fixed args
1121 construction for operators in scm_tcs_cons_gloc case in two args
1124 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1126 * fluids.c: Removed use of assert.h (in order to avoid
1129 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
1131 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
1133 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
1134 change makes the evaluator safer at the cost of evaluation speed.
1135 It handles the case when the user has added a non-immediate
1136 improper end of the application form, e.g., `(+ 0 . x)'.
1137 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
1138 minimize the extra cost as much as possible. The new code is
1139 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
1140 problem with structs planted directly in the code (e.g. by a
1141 macro). This no longer causes segmentation fault. (Thanks to
1144 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
1145 arg `proc' in order to be able to throw errors; New argument
1148 * Removed extra #include "debug.h"
1150 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
1152 * scmsigs.c: Declare usleep as returning void on some systems.
1153 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
1156 * coop.c (usleep): Return void on some systems.
1158 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1160 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
1162 * coop.c: Changed return type of usleep to int.
1164 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
1165 isn't found in the OS.
1167 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
1168 isn't enabled. (Thought that I had made this change ages ago...)
1170 * iselect.c: Declare bzero if not defined by OS.
1172 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1174 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
1175 condition. (Thanks to John Tobey.)
1177 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
1178 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
1181 * __scm.h: Start the long-term project of moving to POSIX threads.
1182 Phase 1: Classification of all critical sections.
1183 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
1184 for A sections. (See comments in __scm.h for details.)
1186 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
1187 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
1189 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1191 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
1192 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
1193 (libpath.h, versiondat.h): Replaced dependency on Makefile with
1194 dependencies on $(srcdir)/Makefile.in
1195 $(top_builddir)/config.status in order to avoid circularity.
1197 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
1198 from argc if argc was 0 initially.
1200 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
1201 in generation of libpath.h.
1203 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
1205 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
1206 libguile from 2 to 3.
1208 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
1210 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
1212 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
1214 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
1215 scm_set_port_column_x, scm_port_filename,
1216 scm_set_port_filename_x): Removed optional arguments. Added
1217 proper argument checking.
1219 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
1220 stack size in machine words.
1222 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
1223 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
1224 to Ole Myren Röhne.)
1226 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
1228 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
1229 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
1231 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
1234 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
1235 procedure apply: Copy argument lists before pushing them unto the
1236 environment so that the environment won't get mutated due to
1237 manipulation of procedure arguments. This should perhaps be
1238 regarded as a temporary solution until someone finds a more
1239 efficient one. (Thanks to Maciej Stachowiak.)
1241 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
1243 * script.c (scm_compile_shell_switches): Use "guile" as default
1244 zero arg if argc is NULL.
1246 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
1248 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
1249 is zero. (Thanks to Dirk Herrmann.)
1251 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
1253 * ports.c (scm_add_to_port_table): First line is now line 0
1254 (was 1). (Interface changed according to suggestion by Per
1257 * backtrace.c (display_header): Add 1 to line and column numbers
1258 when presenting them to the user.
1260 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
1261 from debug.c --> eval.c
1263 * eval.h, eval.c (scm_eval_options_interface): New options
1265 (SCM_EVAL_STACK): New option: Size of newly created stacks,
1266 i.e. stacks for new threads.
1268 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
1270 * eval.c (unsafe_setjmp): Removed with #if 0.
1272 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
1275 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
1276 to avoid compiler warnings.
1278 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
1280 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
1282 * throw.c (handler_message): Print message on current error port
1283 instead of default error port. (Thanks to Maciej Stachowiak.)
1285 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
1287 * ports.c (scm_add_to_port_table): allocate in units of
1288 struct scm_port_table *, not struct scm_port_table.
1289 * posix.c (scm_close_pipe): remove the port from the port table
1291 Thanks to Rob Engle for both fixes.
1293 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1295 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
1296 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
1298 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1300 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
1302 * backtrace.c (display_error_body, display_backtrace_body),
1303 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
1304 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
1305 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
1306 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
1309 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
1310 don't receive the jmpbuf arg anylonger.
1311 (scm_catch): Don't accept a #f tag.
1312 (scm_throw): Check that key is a symbol.
1313 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
1315 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
1317 * async.c (async_pending): Removed declaration.
1319 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1321 * dynwind.c (scm_wind_chain): New debug function.
1323 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
1324 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
1325 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
1326 extra layer of functions around the body and handler of a thread.
1327 This extra layer makes sure that the handler is called in the
1328 dynamic context of the surround (= empty dynwind list), but under
1329 the *dynamic root* of the body. We can not use the dynamic root
1330 of the surround since that root belongs to another thread => stack
1331 is not handled correctly. It may seem ugly to use this extra
1332 layer, but the extra cost in terms of execution time is really
1333 negligible compared to the total amount of time required to create
1334 a thread, and it would reduce maintainability to duplicate the
1335 crucial and complicated steps performed by cwdr.
1337 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
1338 (SCM_ALLOW_INTS): Added thread switching code before interrupts
1339 get re-enabled. The important effect of this is that interrupts
1340 are blocked during thread switching so that thread data structures
1341 don't risk getting messed up by an unfortunate signal.
1342 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
1343 seems to do more aggressive optimization which actually move
1344 instructions around in these macros in a fatal way. Therefore:
1345 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
1346 just superstitious...)
1347 (SCM_TICK): Maybe do a context switch and take care of asyncs.
1348 This macro should be used instead of SCM_ASYNC_TICK since the
1349 latter doesn't do context switches any more.
1351 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
1352 instead of SCM_ASYNC_TICK.
1354 * coop.c, iselect.c: Since thread switches are now performed with
1355 interrupts masked, we can't use the old mechanism of delivering
1356 signals immediately when they arrive. Signals must instead be
1357 delivered when the asyncs run *after* the end of the critical
1358 section in scm_internal_select. But this also means after context
1359 switch so that the signal will be delivered to a different thread.
1360 To avoid this, I have changed the protocol of
1361 coop_wait_for_runnable_thread and friends so that they are allowed
1362 to return the original thread. So, if a signal arrives during
1363 scm_internal_select, we won't any longer be forced do a context
1364 switch, but can remain in the same thread and deliver the signal
1367 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
1368 scm_asyncs_pending and made it global.
1370 * iselect.c: Small fixes.
1372 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
1373 coop_condition_variable_init, coop_condition_variable_wait,
1374 coop_condition_variable_signal): Changed return type from `void'
1375 to `int'. This is to adhere closer to the pthreads interface.
1376 This, in turn, is part of an attempt to provide C versions of the
1377 mutex and condition variable primitives which can be part of a
1378 frontend to COOP or pthreads.
1380 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
1381 coop_condition_variable_destroy): New functions.
1383 * coop-threads.c (scm_wait_condition_variable): Use
1384 coop_condition_variable_wait_mutex.
1386 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
1387 Definitions moved to coop-defs.h.
1389 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
1390 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
1391 scm_cond_destroy): New C interface to mutecis and cond vars.
1393 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1395 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
1397 * iselect.c: Now several threads can wait on the same file
1398 descriptor. The behaviour is compatible with OS select: All
1399 threads waiting for the fd return with the same status.
1401 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1403 * coop-threads.c, threads.h (scm_spawn_thread): New function.
1404 Can spawn a thread from application C code.
1406 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1408 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
1409 gh_doubles2scm): New functions.
1411 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
1413 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
1414 commented-out version of gh_eval_str()
1416 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
1418 * socket.c (scm_bind): free soka after use.
1420 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
1422 * stime.c (tzvar): new variable.
1423 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
1424 avoid memory leaks when allocating.
1426 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
1428 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
1431 * gc.c, tags.h: Doc fixes.
1433 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1435 * eval.c (macro-eval!): Removed. This function was a design bug.
1436 It allowed memoized code to leak out to the scheme level. Most
1437 things that you could do with `macro-eval!' can be done with
1440 1997-12-20 Tim Pierce <twp@skepsis.com>
1442 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
1443 scm_fgets now depends on ftell(3) to know how many bytes were
1446 1997-12-15 Tim Pierce <twp@skepsis.com>
1448 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
1449 dealing with strings.
1451 1997-12-13 Tim Pierce <twp@skepsis.com>
1453 Make %read-line more suitable for implementing read-line efficiently.
1454 * ioext.c (scm_read_line): Strip the terminating newline from a
1455 string, and return a cons of the string and its terminator.
1457 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
1458 of the string that is read is stored in this memory location.
1459 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
1460 * genio.c, genio.h (scm_do_read_line): Update caller.
1461 * ports.h (scm_ptobfuns): Update typedef.
1462 * fports.c (scm_fptob, scm_pipob): Update struct.
1464 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1466 * filesys.c (set_element): Return file descriptor.
1467 (fill_select_type): Return the highest file descriptor.
1468 (scm_select): Tell select about the highest file descriptor. On
1469 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
1470 Therefore the extra overhead for calculating the maximum fd seems
1471 to be more than compensated. Is this correct? In any case,
1472 scm_internal_select will be much faster with this info.
1473 (scm_select, fill_select_type, set_element): Don't accept any kind
1474 of object in the file descriptor list or vector.
1476 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1478 * iselect.c (finalize_fd_sets): Bugfix.
1480 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1482 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1483 when using scm_internal_select (since we might switch to another
1486 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1488 * simpos.c (scm_system): always define: use sysmissing if not
1489 available. Check for HAVE_SYSTEM instead of _Windows (does
1490 Windows lack system or does it have an unusable one?).
1491 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1492 Let the argument be optional: if not supplied, call system(NULL).
1494 * ports.c (scm_close_port): relax the type check from OPPORTP to
1495 PORTP; closing a closed port is allowed.
1497 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1499 * fports.c (scm_fgets): Return if the last char in a chunk is
1500 newline. When fgets returns a string whose length is `size-1', it
1501 is ambiguous whether a whole line was retrieved, so we must check
1502 explicitly whether a line terminator is present.
1504 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1506 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
1507 before taking the CDR. (Thanks to Harald Meland.)
1509 * filesys.c (scm_stat): Slightly optimized.
1511 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
1513 * ports.c (scm_close_port): Make sure the port is open before
1516 * guile-snarf.in: Pass args through to gcc in a way that preserves
1517 whitespace boundaries. (Thanks to Greg Badros.)
1519 1997-12-02 Tim Pierce <twp@skepsis.com>
1521 * stacks.c (scm_frame_procedure): Reverse the logic in the return
1522 statement. (Thanks to Doug Evans for pointing this out.)
1524 1997-12-01 Tim Pierce <twp@skepsis.com>
1526 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
1528 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
1530 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
1531 errno macro expansion of this field name. (errno is a C
1532 preprocessor macro on some systems.)
1534 1997-11-29 Tim Pierce <twp@skepsis.com>
1536 * iselect.c: Doc fix.

1549 * root.h (scm_root_state): Removed the_last_stack_var.
1551 * throw.c: Added #include "fluids.h"

1554 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
1555 --> the_last_stack_fluid.
1557 * backtrace.c: Added #include "fluids.h"
1558 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.

1584 scm_internal_select.
1585 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1586 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1587 replacement in iselect.c.
1588 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1589 coop_join): If GUILE_ISELECT enabled, use
1590 coop_wait_for_runnable_thread instead of
1591 coop_next_runnable_thread.
1592 (usleep, sleep): New replacements for system functions if
1593 GUILE_ISELECT is enabled.
1595 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1597 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1599 * filesys.c: Added #include "iselect.h". Moved FD-macros to

1601 scm_internal_select. (See NEWS.)
1603 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1605 * init.c: Call scm_init_iselect.

1610 1997-11-27 Tim Pierce <twp@skepsis.com>
1612 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1613 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1614 and scm_must_free, since ultimately the string returned will be copied
1615 by scm_makfrom0str anyway. Also, read any characters that may have
1616 been pushed onto the port with scm_ungetc.
1617 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1618 * ioext.c (scm_read_line): Free string after Guilifying it.

1630 gh_repl (argc, argv).
1632 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1634 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1635 and to invoke scm_shell().
1636 (gh_launch_pad): took out the loading of boot-9.scm from here,
1637 since it is probably best to let the user control that. In fact,
1638 gh_repl() now invokes scm_shell() which does that.
1640 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1642 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()

1664 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1665 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1667 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1669 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1670 configure.in was changed).
1672 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
1674 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1675 * Makefile.in: Regenerated.
1677 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1679 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1680 OPORT is an `open' port, not an output port.
1682 * filesys.c (scm_close, set_element, get_element, scm_chown,
1683 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use

1688 scm_set_port_filename_x, scm_port_mode,
1689 scm_close_all_ports_except, scm_set_current_output_port,
1690 scm_set_current_error_port): Likewise
1691 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1692 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
1694 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
1695 * backtrace.c (display_backtrace_body): Likewise
1696 * fports (scm_setvbuf): Likewise
1697 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,

1704 Minor problems with substring-related tag changes.
1705 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1706 exactly what we want to leave in to detect substrings.
1707 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1708 * tags.h: Fix diagrams and comments describing the S tag bit;
1709 remove vestigial remarks about the D tag bit.

1711 * strings.c: Formatting tweaks.
1713 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1714 variable first; then SCHEME_LOAD_PATH, with a warning message.
1715 (scm_parse_path): New function.
1716 * script.c: Doc fixes.
1718 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1720 Readline support, from Daniel Risacher.
1721 * readline.c, readline.h: New files.

1726 * scmconfig.h.in: Regenerated, after change to ../configure.
1728 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1730 * gh.h: gh_vector_set -> gh_vector_set_x
1732 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1734 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1735 with the ! -> _x mapping when going from Scheme to C.
1737 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1739 * gh.h (gh_reverse):
1747 (gh_assoc): added these gh_ functions implemented as macros.

1757 (gh_set_cdr_x): added these routines as I go through and try to
1758 complete the picture R4RS functions that should be mirrored in the
1761 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1763 * tags.h (scm_tc7_substring): Changed the comment and code to
1764 conform with the changes below. Folks! We have suddenly two new
1765 free tc7 codes!!! Jummy, jummy!

1825 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1827 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1829 * gh_test_c.c (c_vector_test): some improvements on the vector
1832 * gh.h (gh_vector): this used to exist but do the wrong thing.
1833 Now it (almost) does the right thing, though it takes a list
1834 instead of the individual arguments. I need to see how it could
1836 (gh_list_to_vector): added this function as a macro. Corresponds
1837 to Scheme's (list->vector ...).
1838 (gh_vector_to_list): added this function as a macro. Corresponds
1839 to Scheme's (vector->list ...).
1841 * gh_data.c (gh_vector_ref): renamed from gh_vref to

1843 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1844 resembles the Scheme routines more.
1845 (gh_make_vector): this used to be (stupidly) called gh_vector().
1846 This is the right name, since it does the same thing as the Scheme
1847 (make-vector ...) procedure.
1849 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1851 * ports.h: #include "libguile/print.h"

1866 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1868 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1869 macros should by convention not test for NIMPness.)
1870 (SCM_COERCE_OPORT): Adjust indentation.
1872 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1873 SCM_NIMP test before SCM_PRINT_STATE_P.

1880 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1882 * struct.c (scm_print_struct): Use new printer slot; Default
1883 printing: Also output hex code of vtable so that type identity
1884 will be indicated as well.
1885 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1886 Removed struct_printer_var; Removed struct-vtable-offset;
1887 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1888 vtable-offset-user): New constants.
1890 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.

1893 the type represented by this vtable.
1895 * print.c (scm_iprin1): Don't print arguments of macro
1896 transformers. (They are always: exp env.); Bugfix: Unmemoize
1897 transformer source with correct environment.

1905 (cwdr_outer_body): Removed.
1906 (cwdr_handler): New function.
1907 (scm_internal_cwdr): New function to perform the function of cwdr
1908 but take args that are more useful to C code. Also, the handler
1909 is now invoked *outside* of the new dynamic root, like the docs
1910 say. We no longer have to catch absolutely all errors, the caller
1911 is responsible for using a handler that does not throw, if he
1913 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1914 * root.h (scm_internal_cwdr): New prototype.
1916 Even more but risky streamlining:
1918 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1919 allocation of the jumpbuf of a root continuation. The changes
1920 below are controlled by it. They are now deactivated.
1921 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1922 the JMPBUF of the scm_rootcont to NULL before returning.
1924 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1925 when they are non-NULL.
1926 (scm_gc_mark): Likewise, mark only when non-NULL.
1928 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1929 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1931 * gc.c (scm_done_malloc): New function.
1932 gc.h (scm_done_malloc): New prototype.

1942 (scm_print_state_vtable): New variable.
1943 (scm_free_print_state): Set `revealed' field to false.
1944 (scm_iprin1): Call user supplied closure printer with
1945 scm_printer_apply. Print in the traditional way when there isn't
1946 one or when it returns #f.
1947 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1948 Accept a port/print-state pair in addition to just a port.
1949 (scm_prin1): Don't return the print_state to the pool when it has
1951 (scm_printer_apply): Set `revealed' field of print_state to true.
1952 (scm_init_print): Set scm_print_state_vtable.
1953 (print_state_fluid, print_state_fluid_num): Removed.
1955 * throw.h (scm_handle_by_proc_catching_all): New prototype
1956 throw.c (scm_handle_by_proc_catching_all): New function
1958 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1960 * Makefile.in: Regenerated with automake 1.2c.
1962 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1964 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1965 was looping endlessly.
1967 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1969 * strports.c (scm_eval_string): Don't close the port.
1971 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1972 former returns a nice normal integer. (Thanks to Daniel
1975 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1977 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1978 makefile variable as a build parameter called LIBS. The
1979 build-guile program will use this, for the time being.
1980 * Makefile.in: Regenerated.
1982 Thanks to Shiro Kawai:
1983 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1984 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1987 * Makefile.in: Regenerated with automake 1.2a.
1989 * script.c (scm_compile_shell_switches): If we hit the -c or --
1990 arguments, don't set the car of (command-line) to scm_usage_name,
1991 the prettified name of the guile executable; give it the full
1992 path, the way shells usually handle $0.
1994 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1996 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1997 Scheme-level name `array-map' and renamed `serial-array-map' to
1998 `serial-array-map!'.
2000 * backtrace.c: Introduced exception handlers which now enclose
2001 `display-error' and `display-backtrace' so that error reporting
2002 won't get into infinite loops if an error occurs during displaying
2003 of the error. This can very easily happen with user supplied
2004 print call-back routines.
2006 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2008 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
2009 the names `serial-array-map' and `array-map' should be removed.)
2011 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
2013 * init.c (scm_boot_guile_1): Added scm_init_objects ().
2014 Added #include "objects.h"
2016 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
2017 Add #include "feature.h".
2019 * Makefile.am (libguile_la_SOURCES): Added objects.c.
2020 (modinclude_HEADERS): Added objects.h.
2022 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
2023 This test is needed at many places in the code and should be
2024 abstracted. (Motivated by the need of this test in libguiletk.)
2026 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
2027 (scm_eval_string), load.c (scm_primitive_load,
2028 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
2029 Use SCM_EOF_OBJECT_P.
2031 * eval.c (scm_init_eval): Add feature `delay'.
2033 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2035 * scmhob.h: Removed.
2037 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2039 * list.h (SCM_LISTn): New macros. Make list creation in C code
2040 prettier. The idea comes from STk.
2042 * sequences.h, sequences.c, append.h, append.c: Removed. These
2043 files implemented non-R4RS operations which would encourage
2044 non-portable programming style and less easy-to-read code.
2046 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
2049 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
2050 sequences.h, #include append.h.
2052 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
2055 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
2057 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
2059 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
2061 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2063 * eval.c: Added #include "objects.h"
2065 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
2068 * smob.c (scm_smob_prehistory): Create two objectsmobs with
2069 adjacent smob numbers.
2071 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2073 * procprop.h: Added declaration of scm_i_inner_name.
2075 * gsubr.c: New global symbol scm_i_inner_name.
2077 * debug.c (scm_procedure_name): Try procedure property
2078 `inner-name' if `name' fails.
2080 * print.c (scm_iprin1): Use scm_macro_name.
2082 * eval.c (scm_m_define): Give names to macros as well; Only the
2083 first top-level definition gives a procedure/macro a name.
2084 Otherwise confusing names can turn up in backtraces.
2085 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
2086 `name'; Give names to macros as well.
2088 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
2089 (scm_macro_transformer): Use SCM_CLOSUREP instead of
2092 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2094 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
2096 (prinmacro): Removed. The code has been moved/merged into print.c
2097 in order to decrease code redundancy. We want macros to print in
2098 a way equivalent to procedures, and it would be silly to duplicate
2099 the required code. (We don't want to maintain two places.)
2100 (macrosmob): Print field is now a NULL pointer.
2102 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
2103 scm_macro_transformer): New prototypes.
2104 (scm_tc16_macro): Declared.
2106 * print.c (scm_iprin1): Added code for printing of macros. Macros
2107 are now printed in a way equivalent to procedures.
2109 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
2111 * procs.h (scm_closure_p): Added declaration.
2113 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2115 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
2116 Shouldn't pass "heap" as the subr name.
2118 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
2120 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
2121 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
2122 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
2123 gh_equal_p): Use SCM_NFALSEP, instead of testing against
2124 SCM_BOOL_T. Any non-false value is true.
2126 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2128 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
2129 scm_gensym): Added prototypes.
2131 * symbols.c (scm_gensym): New function. This will speed up
2132 certain types of applications (such as macro systems) which
2133 generate lots of symbols.
2135 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2137 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
2139 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
2141 * unif.c (scm_shap2ra): tighten the checking of the array dimension
2142 specifier, since (2) or (2 . 3) would cause SEGV.
2143 (scm_transpose_array): more argument checking fixes.
2145 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
2147 * Makefile.in: Regenerated.
2149 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
2151 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
2153 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2155 * error.c, error.h (scm_error_callback): Removed (see NEWS).
2157 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
2159 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
2160 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
2163 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
2164 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
2165 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
2166 scm_array_p, scm_array_rank, scm_array_dimensions,
2167 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
2168 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
2169 scm_array_prototype): Added case scm_tc7_wvect.
2171 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
2173 * errno.h: prototype for scm_strerror.
2174 * error.c (scm_strerror): new procedure.
2176 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2178 * list.c (scm_list_append_x): Allow non-pair as last argument.
2179 This is consistent with the R4RS append and is probably the
2180 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
2182 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2184 * stime.h: prototype for scm_times.
2185 * stime.c (scm_times): new procedure.
2186 * ioext.c (scm_fseek): if the first argument is a file descriptor
2188 (scm_ftell): if the first argument is a file descriptor call lseek
2190 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
2191 * filesys.c (scm_chmod): if the first argument is a file descriptor,
2193 (scm_chown): if the first argument is a port or file descriptor,
2195 (scm_truncate_file): new procedure.
2196 Add DEFER/ALLOW INTS to a few other procedures.
2197 (scm_fsync): new procedure.
2198 (scm_open_fdes): new procedure.
2199 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
2201 (scm_fcntl): the first argument can now be a file descriptor. The
2202 third argument is now optional.
2204 * posix.c (scm_execl, scm_execlp): make the filename argument
2205 compulsory, since omitting it causes SEGV.
2206 (scm_sync): return unspecified instead of #f.
2207 (scm_execle): new procedure.
2208 (environ_list_to_c): new procedure.
2209 (scm_environ): use environ_list_to_c. disable interrupts.
2210 (scm_convert_exec_args): take pos and subr arguments and
2211 improve error checking.
2213 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2215 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
2216 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
2217 argument to SCM_ASSERT. Furthermore, the name of the function
2218 should be passed as first argument when signalling
2219 SCM_WNA. (Thanks to Thomas Morgan)
2221 * gsubr.c (scm_gsubr_apply): From Radey Shouman
2222 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
2223 dispatches on the number of actual args has a default case
2224 reporting an internal error. This is a vestige from a version
2225 that mallocated a SCM vector to hold the arguments. In the
2226 current version this check is too late: if it ever happens we will
2227 have already overstepped the bounds of the array.
2229 Also, the patch [...] adds a check for too many actual arguments."
2231 mdj: Removed check for "internal programming error".
2233 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2235 * gh_io.c (gh_write): New function.
2237 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
2238 throw.c (scm_internal_stack_catch): New sibling to the other catch
2239 functions. Code moved from gh_eval.c.
2240 throw.h: Added header.
2241 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
2242 scm_internal_stack_catch.
2244 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2246 * ioext.h: fix up prototypes.
2247 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
2248 Scheme name is now dup->fdes.
2249 (scm_dup_to_fdes): make the second argument optional and
2250 fold in the functionality of scm_primitive_dup.
2251 (scm_primitive_dup): deleted.
2253 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
2255 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
2256 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
2257 ultrix are defined. Use setvbuf instead of setbuf.
2258 (scm_setvbuf): new procedure.
2259 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
2260 (scm_setfileno): moved from ioext.c.
2261 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
2262 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
2264 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2266 * fluids.c (scm_fluid_p): New function.
2267 * fluids.h (scm_fluid_p): New prototype.

2271 * print.c (scm_iprin1): Enter printed structures into the print
2272 state as nested data while they are printed.
2273 (print_state_fluid, print_state_fluid_num): New variables.
2274 (scm_init_print): Initialize them.
2275 (scm_iprin): If print_state_fluid carries a print_state, use that
2276 instead of creating a new one.
2277 (scm_printer_apply, apply_stub, struct apply_data): New
2278 definitions to help with calling printer functions written in
2280 * print.h (scm_printer_apply): New prototype.
2282 * struct.c (scm_print_struct): Use scm_printer_apply to call the
2283 user defined struct printer.
2285 * dynwind.c (scm_dowinds): Handle fluids on the wind list.

2293 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
2294 SCM_ASSERT: arg comes before pos.
2296 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2298 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
2299 to a list of length zero correctly.
2301 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2303 Supply an `fgets' method for port objects to do fast line i/o.

2317 * ioext.h: removed scm_duplicate_port prototype.
2319 * ioext.c (scm_primitive_dup2): return the new file descriptor
2320 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
2322 (scm_fdopen): bug fix: don't try to make port unbuffered until its
2323 stream has been set.
2324 (scm_duplicate_port): deleted, there's now an implementation in
2326 (scm_primitive_dup2): do nothing if newfd == oldfd.
2328 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
2330 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the

2334 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
2336 * fluids.c (next_fluid_num): don't do
2337 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
2339 * ports.h: prototypes too.
2340 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
2342 * fports.h: prototype too.
2343 * fports.c (scm_evict_ports): moved from ioext.c.
2345 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>

2352 and ports (scsh compatible).
2354 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
2357 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
2359 * fluids.c, fluid.h: New files.
2360 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
2361 (modinclude_HEADERS): Added "fluids.h"

2370 (scm_make_root): Call scm_copy_fluids to make fluid bindings
2371 unique for the new root when it has a parent.
2373 * smob.h: Include "libguile/print.h" to make scm_print_state
2376 * dynl.c (free_dynl_obj): New function to free the dynamic object
2377 data. (dynl_smob): Use it.
2378 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
2379 the dynamic object data below the linking of the object to avoid
2380 memory leak when the linking code throws an error. Now the code
2381 leaks a whole dynamically linked library when must_malloc throws,
2382 but that should be much less likely.
2384 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
2386 Changes to compile under gnu-win32, from Marcus Daniels:
2387 * stime.c (tzset): If tzset isn't provided, make it a NOP.
2388 (scm_localtime): Change SCM_EOF to SCM_EOL.
2389 (scm_mktime): Likewise.
2390 * socket.c: Don't include sys/un.h unless autoconf tells
2391 us Unix domain sockets are available.
2392 (scm_fill_sockaddr): Ignore Unix domain code.
2393 (scm_addr_vector): Likewise.
2394 (scm_init_addr_buffer): Likewise.

2401 was found during autoconf (in this case, getgroups).
2402 (scm_setpwent): For setpwent.
2403 (scm_setegid): For setegid.
2404 * net_db.c (scm_inet_netof): Don't include unless support
2405 function was found during autoconf (in this case, inet_netof).
2406 (scm_lnaof): For inet_lnaof.
2407 (scm_inet_makeaddr): For inet_makeaddr.

2419 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
2420 scm_misc_error, not SCM_EOF.
2422 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
2423 arguments for formatting the error message, not SCM_BOOL_F. I
2424 think this is left over from the (eq? '() #f) days.
2426 * read.c (recsexpr): Give this a dummy definition if
2427 DEBUG_EXTENSIONS isn't #defined.
2429 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
2431 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
2434 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>

2441 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
2442 alloca.lo will be included in @LIBLOBJS@. Something better than
2443 this should be possible.
2444 * Makefile.in: Regenerated.
2446 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2448 * simpos.h: prototype for scm_primitive_exit.
2449 * simpos.c (scm_primitive_exit): new procedure, terminates the
2450 process without unwinding the stack.
2452 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
2454 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
2455 argument and logior its components together, so the user doesn't
2456 have to do this explicitly. Also, if regexp/basic is supplied, then
2457 turn off REG_EXTENDED.
2458 (scm_init_regex_posix): New regexp/basic symbol.
2459 (REG_BASIC): #define this if it is not already present.
2461 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2463 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
2464 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
2465 (CLEANFILES): New target, clean versiondat.h, libpath.h.

2475 * Makefile.in: Regenerated.
2477 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
2478 flag; I don't think we support it.
2479 (scm_make_regexp): Make sure the user doesn't pass the
2482 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
2484 (scm_init_regex_posix): Define constants for the REG_mumble flags;
2485 name them according to the SCSH convention: regexp/mumble.
2487 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
2489 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
2491 * Makefile.am (libpath.h): Include the values of all the standard
2492 Makefile directory variables. Print a message, but don't print
2494 (versiondat.h): Print a message, but don't print all the commands.
2495 * load.c: #include "alist.h".
2496 (init_build_info): New function.
2497 (scm_init_load): Call it.
2498 * Makefile.in: Regenerated.
2500 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
2502 * root.c: Establish a reliable catch-all handler for the new root.
2503 After all the Scheme handler function might signal an error too,
2504 and we don't want to lose that.
2505 (cwdr_inner_body): Renamed from cwdr_body.
2506 (cwdr_outer_body): New function, to establish the user's handler,
2507 and pass control to cwdr_inner_body.
2508 (cwdr): Establish the reliable catch-all handler here, and pass
2509 control to cwdr_outer_body.
2510 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
2511 the user's handler through to cwdr_outer_body.
2512 * throw.c (scm_handle_by_message): Move guts into....
2513 (handler_message): New static function.
2514 (scm_handle_by_message_noexit): New function.
2515 * throw.h (scm_handle_by_message_noexit): New prototype.
2517 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
2518 across this. Only works on GCC. Otherwise, we hope for the best.
2519 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2520 the feeling that real thread systems will not need this...
2522 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2524 Try to detect when people are using one version of libguile and a
2525 different version of ice-9. People have been skewing things and
2526 sending in bug reports.
2527 * Makefile.am (versiondat.h): New file to generate.
2528 * version.c: #include "versiondat.h", to get version info.
2529 (scm_libguile_config_stamp): New function.
2530 * script.c: #include "version.h".
2531 (scm_compile_switches): Call scm_version to get version number.
2532 * scmconfig.h.in, Makefile.in: Regenerated.
2533 * Makefile.in: Regenerated.
2535 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
2536 primitive definitions under their Scheme names.
2538 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2539 1:2. Helps avoid confusion between installed and uninstalled libs.
2541 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2544 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2545 backslash from definition; this should be used like: GDB_INTERFACE;
2547 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2549 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
2550 new port unbuffered until its stream has been set.
2552 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2554 * ports.h: new prototype.
2555 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
2557 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
2559 Make things compile neatly under Sun's C compiler.
2560 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
2561 * extchrs.c (xmbtowc): Make the second arg a normal char, not
2562 unsigned, because that's what the ANSI function takes.
2563 * extchrs.h (xmbtowc): Corresponding change to prototype.
2564 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2566 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2567 argument plain char *.
2568 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2570 * tag.c (scm_tag): Remove unreachable statement.
2571 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2572 top of the word, it should be unsigned.
2574 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2575 is defined, to avoid warnings; it's only used in the
2576 conflict-checking code. Which might go away anyway.
2577 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2578 conditionals; put the label definition in an #if too, to stifle
2581 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2582 ChangeLog-threads in the distribution.
2583 * Makefile.in: Regenerated.
2585 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2587 * guile-snarf.in: Changed regexp to support CPPs that insert
2588 whitespace between lexical tokens (which munges the `%%%' snarf
2591 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2593 * load.c (scm_init_load_path): Append $(datadir)/guile to
2594 %load-path, so modules do not have to be installed in Guile's
2595 current version directory.
2597 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2599 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2600 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2601 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2602 call the sysdep functions with deferred ints.
2603 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2604 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2605 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2608 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2611 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2613 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2615 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2617 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2620 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2622 * eval.c (scm_lookupcar1): New procedure to cope with a race
2623 condition during lookup (when using threads).
2624 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2625 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2628 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2630 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2631 supplied. (Change from Tim Pierce.)
2633 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2635 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2636 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2637 default and not `()'. `#f' is the canonical non-value in Scheme,
2640 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2642 * struct.c (struct_printer): New variable that holds a handle on
2643 the Scheme variable *struct-printer*. This variable can be set by
2644 Scheme code to override the printing of structures.
2645 (scm_print_struct): If struct_printer is set, call it. If it is
2646 not set, or returns #f, print the structure in the old fashion.
2647 Include "eval.h" for scm_apply.
2649 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2651 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2652 scm_struct_i_n_words to get the number of fields, not
2653 -scm_struct_n_extra_words.
2655 On the route to fancier struct printing:
2656 * struct.c (scm_print_struct): New function to print a structure.
2657 Include "genio.h" to support it. This function doesn't do
2658 anything interesting right now, but I think it should be here
2660 * struct.h: Include "print.h" and add prototype for
2662 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2663 print structures ourself.
2665 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2667 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2668 before applying the handler in case it doesn't return.
2670 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2672 * scmsigs.h, async.h: updated.
2674 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2677 * posix.c (scm_uname): interpret only negative values as an error.
2678 Solaris normally returns a positive value.
2680 * script.c (scm_compile_shell_switches): if we are not going into
2681 an interactive repl, set scm_mask_ints to zero so that asyncs can
2684 * simpos.c (scm_system): don't ignore/unignore signals around
2687 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2690 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2691 done in boot-9.scm instead.
2693 * scmsigs.c, async.c: Major rewriting of signal handling code.
2694 (scm_sigaction): new procedure.
2695 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2697 (scm_raise): return unspecified, throw error on failure.
2699 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2701 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2702 feature, to help boot-9.scm decide whether to import the regex
2705 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2707 * eval.c: Include scmconfig.h at the beginning of the file so that
2708 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2711 * regex-posix.c: #include "_scm.h" before conditionally #including
2712 <regex.h>; the former defines HAVE_REGCOMP.
2714 * regex-posix.c: #include <regex.h> conditionally, so the file is
2715 CPP'able (for dependency scanning) even on systems that don't have
2718 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2720 Add new R4RS-compliant syntax for keywords.
2721 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2722 regardless of the setting of the `keywords' read option.
2723 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2724 can be re-read no matter what the setting of the `keywords' read
2727 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2729 Add support for POSIX regular expressions.
2731 * regex-posix.c, regex-posix.h: New files. (Some code
2732 is taken liberally from rx/rgx.c in the old Guile dist.)
2734 * init.c: Include regex-posix.h.
2735 (scm_boot_guile_1): Call scm_init_regex_posix.
2737 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2738 Add regex-posix.[ch] sources.
2739 * Makefile.in: Regenerated.
2741 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2742 to do this automatically? It didn't for me, bleh.)
2744 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2746 * fports.c (print_pipe_port): New function.
2747 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2748 latter doesn't even take the right arguments.
2750 * Makefile.am: Increment shared lib revision number. I think
2751 sometimes the uninstalled Guile finds the installed shared lib;
2752 Gord says doing this might help. As things turned out, I can't
2753 say whether it does.
2754 * Makefile.in: Regenerated.
2756 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2757 passing it as the closure argument to scm_boot_guile. (Bill
2760 * ports.c (print_void_port, putc_void_port, puts_void_port,
2761 write_void_port, flush_void_port, getc_void_port, close_void_port,
2762 noop0): Use ANSI prototypes instead of K&R declarations, so the
2763 initialization of void_port_ptob gets aggressively type-checked.
2764 Fix arguments of print_void_port and write_void_port. (Bill

2798 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2800 * script.c (scm_find_executable): Use prototype-style definition
2801 here; apparently it's not quite right to have const in a prototype
2802 and then use a K&R declaration. I wonder if stuff like this will
2803 go away if we compile with -Wrequire-prototypes, or whatever that
2804 is... (Bernard URBAN)
2806 * scmhob.h: New text from Bernard URBAN.
2808 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2810 * script.c: Don't #define const on hpux. Configure takes care of
2811 this. (Thanks to Larry Schwimmer.)
2813 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2814 decide whether to #include <unistd.h>, instead of listing a bunch
2815 of systems. Don't #include stdio twice. Removed dyked-out
2816 definition of scm_find_impl_file.
2818 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2820 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2821 library version info to 1:0.
2822 * Makefile.in: Regenerated.
2824 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

2828 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2829 throw.c: Update copyright years; these files have been worked on
2830 significantly in 1997, but only had copyright years for 1996.
2831 Also, change name of copyright holder on some from Mikael
2832 Djurfeldt to Free Software Foundation; he has signed papers
2833 assigning the changes to the FSF.
2835 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2836 reason not to give the user the option.
2838 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2839 Return #f on end-of-file when scanning table (i.e. when called
2840 with no arguments). Try to catch errors, when we can.
2841 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2843 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2844 external declarations. These are useful.
2846 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2848 * posix.c: don't include <sys/select.h> or define macros for
2849 select, since they were not used in this file.
2851 * filesys.c (scm_select): make the fifth parameter microseconds,
2852 not milliseconds. let the fourth parameter be either a real value
2853 or an integer or #f. The first, second and third arguments can
2854 now be vectors: the type of the corresponding return set will be
2856 (set_element, get_element): new static procedures.
2858 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2860 * strports.c (scm_eval_string): New function.
2861 (scm_eval_0str): Trivially re-implemented in terms of
2863 * strports.h (scm_eval_string): New extern decl.
2865 * net_db.c (h_errno): Add extern decl for this.
2867 * fports.c (local_pclose): New function.
2868 (scm_pipob): Use it in the initializer here.
2871 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2872 Use a meaningful error message when signalling an error. For
2873 this, scm_gethost must check h_errno rather than errno.
2875 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2877 * Makefile.in: Regenerated, using automake-1.1p.
2879 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2881 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2882 not SCM_UNSPECIFIED.
2884 * script.c (scm_compile_shell_switches): don't append (quit) if
2886 (scm_shell): call scm_exit_status and exit on the result of the
2889 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2891 Ensure that shared substrings are handled properly when passed to
2892 a system call or other foreign function. Many thanks to Tim
2894 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2895 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2896 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2897 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

2912 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2914 * error.c (scm_error): Add newline to error message.
2916 * init.c (scm_init_standard_ports): Doc fix.
2918 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2920 * dynl-shl.c: Completely replaced with new code from Bernard
2923 * script.c (scm_ice_9_already_loaded): New variable.
2924 (scm_compile_shell_switches): Use it.
2926 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2928 * filesys.c (scm_input_waiting_p): add missing third argument to
2931 * stime.c (scm_localtime): copy the result of localtime before
2932 calling gmtime in case they share a buffer.
2933 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2936 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2938 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2940 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2942 * Makefile.am (check-local): New target, which causes 'make check'
2943 to run gh_test_c and gh_test_repl, with some trivial input.
2944 * Makefile.in: Rgnrtd.
2946 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2948 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2951 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2953 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2954 sure how this was supposed to work.
2955 (scm_async_click): don't send SCM_TICK_SIGNAL.
2956 (scm_init_async): don't initialize %tick-thunk.
2958 * the following change doesn't affect the Scheme interface:
2959 gc-thunk is called at the end of garbage collection. however it's
2960 no longer implemented by pretending it's a signal.
2962 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2963 system async corresponding to scm_gc_thunk.
2964 * async.h: declare scm_gc_async.
2965 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2966 gc-thunk directly, instead of going through a signal handler.
2967 (scm_gc_async): new variable, points to the GC system-async.
2968 (scm_init_async): save the GC async as scm_gc_async instead
2969 of using system_signal_asyncs.
2970 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2972 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2974 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2975 Don't screw up if we're interrupted.
2976 * Makefile.in: Regeneradet.
2978 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2980 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2982 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2983 we're not using AM_INIT_GUILE_MODULE any more.
2984 * Makefile.in: Reneregated.
2986 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2988 Functions for finding variable bindings, grace à Tim Pierce.
2989 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2990 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2992 Get 'make dist' to work again.
2993 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2994 * Makefile.in: Regenerated, like a surry without a fringe on top.
2996 Changes for reduced Guile distribution: one configure script,
2998 * configure.in, configure: Removed.
2999 * acconfig.h, acinclude.m4: Moved to parent directory, where the
3000 real configure script lives.
3001 * Makefile.in, scmconfig.h.in: Regenerated.
3003 * init.c: #include "script.h", to get prototype for script.c's
3006 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
3008 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
3009 scm_must_malloc, not raw malloc.
3011 * script.c (scm_compile_shell_switches): Dyke out debugging output
3014 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3016 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
3018 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
3019 system has them. Hope this is safe. Previously
3020 sys/timeb.h was included if HAVE_FTIME was defined or if
3021 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
3022 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
3024 * ioext.c (scm_setfileno): add missing third argument to
3025 scm_misc_error call.
3027 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
3029 * eq.c (scm_equal_p): Correctly compare strings of different
3030 varieties. (Thanks to Tim Pierce.)
3032 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
3034 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
3035 #! block comment must occur on a line all by itself.
3037 Move most of the guts of shell command processing into libguile,
3038 so guile.c can be very small (and eventuallly auto-generated. (I
3039 mean, generated mechanically, not self-generated. Hmm.))
3040 * guile.c, script.c, script.h: New source files.
3041 * init.c (scm_boot_guile_1): Call scm_init_script.
3042 * libguile.h: #include "script.h".
3043 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
3044 targets, for new executable.
3045 (libguile_la_SOURCES): Mention script.c.
3046 (modinclude_HEADERS): Add script.h.
3047 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
3048 not dynamic linking is enabled. This is because we're generating
3049 executables now. Move CY_AC_WITH_THREADS call after those, so the
3050 values of cy_cv_threads_libs captures the libs chosen above.
3051 * Makefile.in, configure, aclocal.m4: Regenerated.
3053 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
3054 We don't maintain this interface any more, and it just confuses
3057 * alloca.c: #include <scmconfig.h>, not <config.h>.
3058 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
3059 it'll get included in disties.
3061 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
3063 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
3064 be distributed, because they confuse people.
3065 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
3067 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
3069 * configure.in: check for presence of gethostent (not present on
3070 OpenBSD by default).
3071 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
3072 * configure, scmconfig.h.in: Regenerated.
3074 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
3076 * backtrace.c (scm_backtrace): Split message string across
3077 newlines properly. GCC is more tolerant of this than other

3086 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
3088 (modinclude_HEADERS): Add threads.h, coop-defs.h.
3089 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
3090 coop-threads.c.cygnus, coop-threads.h.cygnus.
3091 * configure.in: If we're using threads, include threads.o in
3093 * _scm.h, libguile.h: threads.h lives in this directory now.
3094 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
3095 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
3096 currently used, but brought along for information's sake.
3097 * ChangeLog-threads: log from old 'threads' directory.
3098 * Makefile.in, configure: Rebuilt.
3100 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
3102 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
3105 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
3107 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
3109 Merge GH interface library into libguile.
3110 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
3111 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
3112 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
3113 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
3115 (EXTRA_libguile_la_SOURCES): ... here.
3116 (pkginclude_HEADERS): Add variable, to get gh.h installed.
3117 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
3118 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
3119 New variables, describing how to build the gh test programs.
3120 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
3121 build the test programs, and we probably should have been linking
3122 libguile.la against them all along, to support AIX shared libs.
3123 Add cflags for threads to CFLAGS; add libs for threads to new
3124 variable THREAD_LIBS, used in Makefile.am.
3125 * ChangeLog-gh: log from old `gh' subdirectory.
3126 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
3128 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
3130 * acconfig.h: Undo change of Apr 9; including the definition of
3131 PACKAGE in the guile headers conflicts with applications' own
3133 * scmconfig.h.in: Regenerated.
3135 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

3144 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
3146 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
3147 have S_IFSOCK. This is the case under Ultrix.
3149 * posix.c (scm_status_exit_val, scm_status_exit_val,
3150 scm_status_term_sig, scm_status_stop_sig): Modified to work with
3151 Ultrix versions of WIFSTOPPED, etc., which assume that their
3152 arguments are lvalues (hmm).
3154 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
3156 * eval.c: Doc fixes.
3158 * throw.c: Doc fixes; rearranged.
3160 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
3162 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
3164 * acconfig.h: Added entry for PACKAGE.
3165 * scmconfig.h.in: Regenerated.
3167 Changes to work with automake-1.1n, which has better libtool support.
3168 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
3169 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
3171 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
3173 * Makefile.in: Rebuild.
3175 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3177 * stime.c (scm_mktime): take an optional zone argument.
3178 (scm_localtime): check putenv return value.
3179 (scm_strftime, scm_strptime): moved from posix.c. move #include
3181 stime.h, posix.h: update prototypes.
3182 (bdtime2c, setzone, restorezone): new static procedures.
3183 (scm_mktime, scm_strftime): use them.
3184 (scm_strftime): don't call mktime before strftime. Use
3185 filltime for return value.
3186 (filltime): convert NULL zname to #f.
3187 (scm_strptime): return a count of characters consumed, not
3188 the remaining string.
3190 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3192 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
3193 (scm_mktime): likewise.
3195 Uncomment localtime and mktime.
3197 * configure.in: add AC_STRUCT_TIMEZONE.
3199 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3201 * stime.c (scm_init_stime): don't define ticks/sec.
3202 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
3203 return value problem and is still portable.)
3205 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3207 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
3208 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
3209 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
3210 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
3211 cpp_err_symbols.c): Corresponding changes.

3217 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
3218 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
3219 * putenv.c: new file, from sh-utils 1.12.
3221 * posix.c (scm_environ): use malloc in place of scm_must_malloc
3222 since allocation isn't for Scheme objects.
3223 (scm_putenv): copy strings before placing in the environment.
3225 * stime.c (scm_current_time): throw an error if time returns -1,
3226 instead of returning #f.
3227 (scm_get_internal_real_time, scm_get_internal_real_time): use
3228 scm_long2num for return value instead of SCM_MAKINUM.
3230 * stime.h: prototypes updated.
3232 * stime.c (scm_time_in_msec): apparently unused, deleted.
3234 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
3236 * configure.in: check for gettimeofday.
3238 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
3239 which may be more usefully portable than a gettimeofday interface.
3241 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
3243 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not

3249 * stime.c (filltime): recovered static procedure.
3250 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from

3254 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
3256 * posix.c (scm_mknod): split the mode argument into type and perms
3257 arguments, like the extra fields returned by stat.
3259 * fports.c (scm_pipob): set the close, free and print procedures.
3260 (scm_close_pipe): new procedure.
3262 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
3263 define them in boot-9.scm
3265 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3267 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
3268 wan't defined. Don't include fd.h.
3270 * Previously fd.h was regenerated whenever configure was run,
3271 forcing a couple of files to be recompiled.
3273 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
3274 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
3275 Check for _fileno as well as _file.
3277 * ioext.c: don't fd.h.
3278 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
3281 * Change the stratigy for getting information about errno
3282 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
3283 generating lists of symbols during the build process, which will
3284 not always work, include comprehensive lists in the distribution.
3285 To help keep the lists up to date, the "check_signals" and
3286 "check_errnos" make targets can be used.
3288 * configure.in: don't check for a command to extract errno codes.
3289 * Makefile.am: update file lists, remove errnos.list and errnos.c
3290 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
3291 check_errnos targets.
3292 (CLEANFILES): remove errnos.c and errnos.list, add
3293 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
3294 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
3295 * errnos.default: deleted.
3296 * cpp_signal.c: new file.
3297 * cpp_errno.c: renamed from errnos_get.c.
3298 * cpp_err_symbols, cpp_sig_symbols: new files.
3299 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
3300 * error.c (scm_init_error): #include cpp_err_symbols instead of
3302 * posix.c (scm_init_posix): don't intern signal symbols. #include
3305 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
3307 * strop.c (scm_i_index): allow the lower bound to be equal to the
3308 length of the string, so a null string doesn't always give an error.
3310 * posix.h: new prototypes.
3311 * posix.c (scm_status_exit_val, scm_status_term_sig,
3312 scm_status_stop_sig): new functions, as in scsh. They break down
3313 process status values as returned by waitpid.
3315 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
3317 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
3318 configure doesn't know about it.
3320 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3322 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
3324 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
3325 which defines C variables with global linkage.
3327 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3329 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
3332 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
3334 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
3335 has time to check why this doesn't work well with continuations.
3337 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
3339 * Fix shell syntax error; some shells won't tolerate
3340 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
3342 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3344 * posix.c (scm_uname): throw an error if uname fails instead
3347 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
3349 * error.c (err_head, scm_errno, scm_perror): obsolete procedures

3354 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3356 * acconfig.h: Removed PACKAGE.
3358 * scmconfig.h.in: Regenerated.
3360 * snarf.h: g++ says it's non-portable not to specify the first
3361 argument in a varargs declaration. I introduced the first
3362 argument by using preprocessor conditionals.
3364 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
3366 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
3367 (scm_freopen): use RO string macros for filename and modes.
3368 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.

3371 (scm_mknod): use RO string macros for path.
3373 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
3374 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
3376 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
3377 use SCM_ROSTRINGP and SCM_ROCHARS.

3381 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
3384 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,

3386 support for byte vectors.
3388 * print.c (scm_iprin1): Limit number of vector elements printed
3389 according to pstate->length.
3391 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>

3396 * error.h: prototype for scm_error_scm.
3398 * error.c (scm_error_scm): new procedure, reimplements scm-error
3399 in C and uses scm_error.
3401 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3403 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
3404 pointer to the Scheme variable read-hash-procedures and intern it
3405 in scm_init_read. Modify scm_read_hash_extend and
3406 scm_get_hash_procedure to use the pointer.
3408 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3410 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
3411 (SCM_KEYWORD_STYLE): defined.
3413 * read.c (scm_read_opts): add a keywords option. This isn't a
3414 boolean option, in case someone wants to add support for DSSSL
3416 Setup scm_keyword_prefix symbol.
3417 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
3419 I've left keyword support disabled by default, since it doesn't
3420 seem to break the module system and it gives R4RS standard behaviour.
3421 It can be reactivated with (read-set! keywords 'prefix).
3423 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3425 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
3426 before constructing arbiter.
3428 * eval.c (scm_m_define): Bugfix: Check that the object is a
3429 closure before setting the procedure property!
3431 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
3433 * ports.c: Removed `ungetc-char-ready?'.
3435 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
3437 * read.c (scm_init_read): intitialise scm_read_hash_procedures
3438 (idea from Mikael: make it a pair so scm_permanent object only
3440 (scm_read_hash_extend): don't call scm_permanent_object.
3441 (ideas from Mikael): if chr is already in the list, replace its
3442 procedure instead of appending it again. If proc is #f, remove
3444 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
3446 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
3448 * gdbint.c (gdb_read): update scm_lreadr usage.
3450 * load.h: update prototypes.
3452 * load.c (scm_primitive_load, scm_read_and_eval_x,
3453 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
3455 * read.h: add prototype for scm_read_hash_extend. Change args for
3458 * read.c (scm_read_hash_procedures): new variable.
3459 (scm_read_hash_extend): new procedure.
3460 (scm_get_hash_procedure): new procedure.
3461 (scm_lreadr): use scm_get_hash_procedure instead of an argument
3462 for extended # processing.
3463 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
3464 scm_read_token): remove case_i, sharp arguments. Change callers.
3466 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
3468 * read.h (SCM_N_READ_OPTIONS): increase to 3.
3469 (SCM_CASE_INSENSITIVE_P): define.
3471 * read.c: add case-insensitive option to scm_read_opts.
3472 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
3473 to determine whether to convert symbol case.
3474 (default_case_i): definition removed.
3475 * read.c (scm_read_token): if case_i, downcase ic before doing
3478 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3480 * configure.in: Added configuration option `guile-debug'.
3481 Configure with --enable-guile-debug if you want a bunch of extra
3482 functions used for debugging when developing Guile.
3484 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3486 * procs.c (make-cclo): New undocumented debugging procedure: Make
3487 compiled closure with internal procedure PROC and length LENGTH.
3488 Only compiled if GUILE_DEBUG is defined.
3490 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3492 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3494 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3496 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3497 with 3 or more args internally to the evaluator.
3499 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3501 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3502 with 3 or more args internally to the evaluator. This is mainly
3503 because we don't want to pass entry and exit points of the
3504 debug support twice, but it also seems to increase the speed of
3505 the evaluator for such calls (e. g. (+ 1 2 3)).
3507 * backtrace.c (scm_display_application): New procedure:
3508 display-application; Set fancy printing parameters individually
3509 for different types of display (backtrace, error, application).
3510 (These should of course be customizable!)
3512 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3513 clear the CHECK-flags.
3515 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3517 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3519 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3521 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3522 from pairs with a GLOC in the car.
3524 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3525 otherwise `symbol-hash' will behave badly.
3526 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3527 we get segmentation fault!
3529 * symbols.c: Added #include "weaks.h". New functions:
3530 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3531 moved to an extraneous library when we split libguile.)
3533 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3535 * filesys.c (scm_stat): stat now takes fport arguments too as
3536 documented in the manual.
3538 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3540 * debug.c (scm_single_step): Bugfix: Call continuation with
3541 scm_call_continuation instead of throwing to it.
3543 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3545 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3546 argument wasn't declared to be optional.
3548 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3550 * stime.c (scm_init_stime): Add feature "current-time".
3552 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3554 * throw.h: prototype for scm_exit_status.
3555 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3556 args to derive an exit status. Allows (quit) to work from a
3558 (scm_exit_status): new function.
3561 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3563 * eval.c (scm_deval): Removed some old code.
3564 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3566 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3569 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3572 * procs.c: Introduce the existent C function scm_thunk_p at the
3573 Scheme level as well.
3575 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3577 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3578 used from C to easily lookup the value of a symbol in the current
3581 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3583 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3584 scm_init_unif in this file. This will also fix a previous problem
3587 * configure.in: Added AM_MAINTAINER_MODE
3589 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3591 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3594 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3596 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3597 source files that are not always included in libguile but should
3598 have their dependencies calculated by automake. This variable is
3599 recognized by automake, no further magic is needed.
3600 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3601 to deal exclusively with *.lo files, as it seems. The *.o files
3602 are built automatically when the corresponding *.lo file gets
3605 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3607 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3610 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3612 * unif.c (scm_array_set_x): minor change to argument error checking.
3614 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3616 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3617 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3618 They should only be included in the library at configure.in's
3620 (libguile_la_LDADD): Include the appropriate .lo files here.
3621 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3622 so we know when to build them (and their .lo bretheren).
3623 * configure.in (LIBLOBJS): New substituted variable. We let
3624 configure decide which .o files to include in LIBOBJS, and then
3625 put the corresponding list of .lo files in LIBLOBJS. The latter
3626 is what we pass to libtool.
3627 * Makefile.in, configure: regenerated.
3629 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3631 * symbols.c (scm_sysintern0): New function. Contains the core of
3632 old scm_sysintern but doesn't take a second value argument.
3633 (scm_sysintern): Now uses scm_sysintern0.
3634 (scm_sysintern_no_module_lookup): Renamed to
3635 scm_sysintern0_no_module_lookup and doesn't take a second value
3636 argument any longer.
3638 * symbols.h (scm_sysintern0: Added declaration.
3640 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3641 scm_sysintern when interning option keys. Otherwise we risk
3642 destroying the values of already interned variables.
3644 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3645 scheme-level boolean (use SCM_NFALSEP).
3647 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3649 (scm_backtrace): New function. (C version of old function from
3650 boot-9.scm) Motivation: Make it possible to display backtraces
3651 without depending on boot-9.scm. (I'm uncertain if this
3652 motivation is good enough...)
3654 * root.h (scm_root_state): Add member the_last_stack_var.
3655 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3657 * root.c (mark_root): Mark scm_the_last_stack_var.
3659 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3662 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3664 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3665 1. mark_lazy_catch didn't mark the smob.
3666 2. Both functions above have standard variants:
3667 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3668 free_lazy_catch --> scm_free0.
3670 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3672 * throw.c (scm_internal_lazy_catch): New function.
3673 (scm_lazy_catch): Rewritten to use it.
3674 (scm_ithrow): Handle the new lazy catch representation.
3675 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3676 that doesn't have a jmpbuf is a lazy catch clause.
3677 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3678 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3679 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3681 (scm_init_throw): Register the new lazy-catch smob type.
3682 * throw.h (scm_internal_lazy_catch): decl for new function.
3684 * throw.c (scm_internal_catch): Doc fixes.
3686 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3687 configure.in. Including this might cause problems if applications
3688 that link against libguile include their own copies of alloca, but
3689 if they're using autoconf, they should be adding libguile to LIBS
3690 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3691 the copy in libguile, and things will be okay. (I think.)
3693 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3695 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3697 strop.h: move prototypes too.
3699 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3701 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3704 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3705 etc. I deleted them from filesys.c long ago, but didn't
3706 notice they were here too (although ineffective since
3707 sys/stat.h wasn't included).
3709 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3711 * eval.c: Don't define alloca in GCC case. gcc will automatically
3712 use __builtin_alloca if appropriate.
3714 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3716 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3717 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3718 that values of automatic variables are preserved. See comments
3719 for safe_setjmp for details.
3721 Change from Thomas Morgan:
3722 * variable.c: Include eq.h.
3723 (var_equal): New function.
3724 (variable_smob): Use var_equal as the discriminator for variables.
3726 * throw.c (s_throw): Remove extraneous declaration.
3728 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3729 * eval.c: Add necessary CPP cruft to support that.
3730 * configure, Makefile.in, scmconfig.h.in: regenerated.
3732 Change from Thomas Morgan:
3733 * procprop.c (scm_procedure_properties): Convert the Scheme
3734 boolean returned by scm_procedure_p into a C boolean before using
3735 it as a condition for SCM_ASSERT.
3736 (scm_procedure_property): Likewise.
3738 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3739 indications of Unixness.
3742 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3744 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3746 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3748 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3749 "unknown # object" error messages.
3751 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3752 (scm_i_index) and declare it static. Add a 'direction' argument
3753 to indicate what way the search should go.
3754 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3756 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3757 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3759 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3761 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3763 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3764 to avoid clash with various scsh forks.
3766 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3768 The following two changes (ramap.c, throw.c) are motivated by the
3769 apparent unportability of forward declarations of static arrays of
3770 the form `static foo bar[];'.
3772 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3773 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3775 * throw.c (scm_throw): Moved above scm_ithrow.
3777 * options.h: Removed the extern declarations of scm_yes_sym and
3778 scm_no_sym since these are static.
3780 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3782 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3784 * Makefile.am: remove AWK=@AWK@.
3785 Add a rule for generating errnos.list.
3786 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3788 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3789 don't extract errnos, just set a variable (avoids the
3790 need to recompile error.c just because configure is run.)
3792 * unif.h: update prototypes.
3793 * unif.c (scm_uniform_array_read,write): change the offset and
3794 length arguments to start and end, for consistency.
3796 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3798 * ioext.h: update prototypes.
3799 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3800 scm_read_line_x, it's a more general procedure using an
3801 interface from scsh. read-line and read-line! are now defined
3803 Note that the new read-line trims the terminator
3804 by default, previously it was appended to the returned string. An
3805 optional argument specifies how to process the terminator (scsh
3806 compatible). For the old behaviour: (read-line port 'concat).
3807 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3808 returns a pair, but is converted to multiple values if the scsh
3811 socket.h: update prototypes.
3812 * socket.c (scm_recvfrom): for consistency with other procedures,
3813 take start and end as separate optional arguments.
3814 (scm_recv, scm_recvfrom): don't allow the second argument
3815 to be a size, only a buffer. Change the scheme names to
3816 recv! and recvfrom!. Don't return the buffer.
3818 * ioext.h, posix.h: move prototypes too.
3819 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3820 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3821 "read.h" and "unif.h".
3822 * ioext.c: include "chars.h"
3824 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3826 * dynl.c: The dynamic linking and module registration functions
3827 are now defined even when dynamic linking is not available for the
3828 host system. Some of their functionality can be done without
3829 dynamic linking; when it's really needed, they throw errors.
3831 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3833 * configure.in: Only define DYNAMIC_LINKING when one of the system
3834 dependent functions is detected.
3835 * dynl.c (scm_dynamic_func): New function to get the address of a
3836 function in a dynamic object.
3837 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3838 produced by scm_dynamic_func as the thing to call.
3840 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3842 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3843 (scm_register_module_xxx, scm_registered_modules,
3844 scm_clear_registered_modules): New functions.
3846 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3848 * symbols.c (scm_sysintern): Renamed to
3849 scm_sysintern_no_module_lookup.
3850 (scm_sysintern): New function to take the place of the old
3851 scm_sysintern. It uses the current toplevel lookup closure to give
3852 the symbol its value. This is a temporary hack to put packages
3853 like gtcltk into their own module.
3854 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3855 us whether `scm_top_level_lookup_closure_var' has been initialized
3857 * eval.c (scm_init_eval): Set it.
3859 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3861 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3862 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3864 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3866 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3867 scm_sys_dup): deleted: FD capability will be added to other
3869 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3870 scm_fd_free, fd_smob, scm_intern_fd.
3871 (scm_open): renamed from scm_sys_open. Return a port instead of
3872 an FD object. Make the mode argument optional.
3873 (scm_sys_create): deleted, it's just a special case of open.
3874 (scm_init_filesys): move interning of constants O_CREAT etc.,
3875 here (were previously using SCM_CONST_LONG macro).
3876 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3878 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3879 include "fports.h" and <stdio.h>
3880 (scm_stat, scm_select): don't support FD objects.
3882 * error.h: adjust scm_syserror_msg prototype.
3883 * error.c (scm_syserror_msg): take an extra argument for errno.
3884 Using the global value didn't always work, since it could be
3885 reset by procedure calls in the message or args arguments.
3887 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3888 I don't understand why the check was there (and what about the
3891 * strop.c (scm_string_copy): allow shared substrings to be copied.
3893 * unif.h: corresponding change to prototypes.
3894 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3895 recognize two new optional arguments: offset and length. Allow
3896 the port argument to be an integer (file descriptor, for scsh).
3897 Include <unistd.h> for "read" prototype.
3899 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3901 * socket.c: don't include filesys.h.
3903 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3905 * Makefile.am: add AWK=@AWK@ (?)
3907 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3909 Add a rule to generate errnos.c from errnos.
3910 * error.c (scm_init_error): include errnos.c.
3911 * errnos_cnvt.awk: new file, converts the list of errno codes to
3913 * errnos_get.c: new file.
3914 * errnos.default: new file, contains errnos to try if they can't
3915 be extracted from errno.h.
3916 * configure.in: if using GCC, try and extract errno codes from
3920 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3922 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3923 * Makefile.am: Made libguile into a libtool library.
3924 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3925 Set libtool_libs to indicate that libguile is a libtool library.
3926 See guile/ChangeLog for details.
3927 * .cvsignore: ignore "*.lo", the libtool library objects.
3929 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3931 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3932 use htons in getservbyport argument.
3934 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3936 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3937 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3940 * objprop.c (scm_object_property): No need to take the CDR of the
3941 value returned by scm_object_properties, since Aug 20 change.
3943 * configure.in: When checking for struct linger, #include
3944 <sys/types.h> as well as <sys/socket.h>. I've never known
3945 <sys/types.h> to cause any portability problems, and Solaris's
3946 <sys/socket.h> needs it.
3947 * configure: Rebuilt.
3949 I think the Sun compiler has chosen a perverse way to interpret
3950 ANSI declarations combined with K&R definitions. We'll
3951 appease it a little bit. But when it invades France, we fight.
3952 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3953 * print.h (scm_iprlist): Here too.
3954 * numbers.c (scm_divbigdig): Change definition to match
3955 declaration in numbers.h.
3956 * unif.c (scm_makflo): Change definition to match declaration in
3959 * init.c (scm_boot_guile): Don't return the value of
3960 scm_boot_guile_1. This function doesn't return a value;
3961 scm_boot_guile_1 doesn't return a value (or return at all).
3963 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3966 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3967 compile. I have a feeling this function is a bad idea anyway ---
3968 one should always test for features, not systems.
3970 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3971 semicolons. Only pure luck kept this from being noticed earlier.
3973 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3975 * socket.c (scm_recvfrom): Added missing semicolon.
3977 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3979 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3980 the buffer and start and end positions for scsh networking
3983 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3985 * configure.in: Revert previous change to this file; the problem
3986 is due to transient automake weirdness.
3987 * configure: Rebuilt.
3989 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3990 PLUGIN/guile.libs. configure generates the latter from the former.
3991 * Makefile.in: Rebuilt.
3993 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3994 need this if we install scripts, like guile-snarf.
3995 * configure: Rebuilt.
3997 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3999 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
4001 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
4003 * socket.c (scm_addr_vector): fix faulty scm_listify.
4005 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
4007 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
4008 style block comment is no longer considered an error.
4010 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
4012 * PLUGIN/guile.libs.in: New file.
4013 * PLUGIN/guile.libs: Removed from repository.
4014 * configure.in: Create PLUGIN/guile.libs from
4015 PLUGIN/guile.libs.in. This is for including additonal libraries
4016 needed for dynamic linking.
4017 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
4018 instead of PLUGIN/guile.libs.
4020 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
4022 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
4024 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
4025 occurrences of the given element from the list, not just the
4026 first. This is how the Emacs Lisp functions behave, how the
4027 analogous Common Lisp functions behave, and (I believe) how the
4028 older Maclisp functions worked. I realize that this change may
4029 break code, but it seemed better to break it before the Guile
4032 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
4033 Their prototypes were already present in gc.h, but they weren't
4035 (scm_init_storage): Initialize scm_protects.
4036 * root.c (scm_protects): New element of scm_sys_protects.
4038 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
4040 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4042 * libguile.h: Added #include "libguile/net_db.h".
4044 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
4045 30 change. That file is only meant for communication between the
4046 configuration process and load.c. If code linked against libguile
4047 wants to get at the paths mentioned in libpath.h, it can call
4048 functions declared in load.h.
4050 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4052 * libguile.h: Removed #include "libguile/fdsocket.h"
4054 * net_db.c: Added #include <sys/socket.h>.
4056 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
4058 * filesys.c (scm_input_waiting_p): use select in preference to
4059 FIONREAD, since the latter doesn't detect EOF.
4060 Throw error if neither select nor FIONREAD available.
4062 * socket.c (scm_connect): take a port, not a fd object.
4063 (scm_fill_sockaddr): throw an error if fam is not recognised.
4064 (scm_bind): use scm_fill_sockaddr.
4065 (scm_listen): take a port, not a fd object.
4066 (scm_accept): take and return a port. return #f in the car if
4067 address can't be got
4068 (scm_sock_fd_to_port): new procedure.
4069 (scm_socket): use scm_sock_fd_to_port.
4070 (scm_addr_vector): throw error if unrecognised address type.
4071 take an extra argument with the calling procedure name.
4072 (scm_getsockname): take a port. return #f if address can't be got.
4073 (scm_getpeername): take a port. return #f if address can't be got.
4074 (scm_recvfrom): take a port. return #f for address component if can't
4076 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
4077 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
4079 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
4081 * throw.c (scm_internal_catch): Make body funcs and handler funcs
4082 use separate data pointers, to allow them to be designed
4083 independently and reused.
4084 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
4085 Renamed from catch_body, catch_handler, and uncaught_throw; made
4087 (struct scm_catch_body_data): Renamed from catch_body_data; moved
4089 (scm_catch): Use the above.
4090 (scm_throw): Don't bother printing a message for an uncaught
4091 throw; we establish a default handler in init.
4092 * throw.h (scm_internal_catch): Prototype updated.
4093 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
4095 (struct scm_body_thunk_data): New structure, used as data
4096 argument to scm_body_thunk.
4097 * init.c (struct main_func_closure): New structure, packaging up
4098 the data to pass to the user's main function.
4099 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
4100 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
4101 scm_internal_catch to establish a catch-all handler, using
4102 scm_handle_by_message. This replaces the special-case code in
4104 (invoke_main_func): Body function for scm_internal_catch; invoke
4105 the user's main function, using the main_func_closure pointer to
4106 decide what to pass it.
4107 * root.c (struct cwdr_body_data): Remove handler_proc member.
4108 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
4109 (cwdr_handler): Removed.
4111 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4113 * socket.h (SCM_P): update bind prototype.
4114 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
4115 include "feature.h".
4116 (scm_socket): return a port, not a file descriptor object.
4117 include "fports.h" and <unistd.h>
4118 (scm_bind): take a port, not a file descriptor object.
4119 take an extra argument for address args.
4121 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
4122 INADDR_NONE, INADDR_LOOPBACK.
4124 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4126 * init.c: include net_db.h and not fdsocket.h.
4127 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
4129 * Makefile.am: corresponding changes.
4130 * socket.h: renamed from fdsocket.h, fix names.
4131 * net_db.h: renamed from socket.h, fix names.
4132 * socket.c: renamed from fdsocket.c.
4133 remove _sys from procedure names.
4134 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
4135 add "socket" to features list.
4136 * net_db.c: renamed from socket.c.
4137 remove _sys from procedure names.
4138 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
4139 add "net-db" to features list.
4140 include "net_db.h". don't include <sys/socket.h> or
4143 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4145 * tags.h (scm_tags): Removed comma at end of last enumerator.
4147 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
4149 Don't use GCC extensions to allocate space for debugging frames.
4150 (Here he goes again! Why do we put up with this?!)
4151 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
4152 an scm_debug_info structure, not an in-line array of them. Add
4153 'info' member, to say how many vect elements we've used, for eval
4155 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
4156 a new variable debug_info_end to mark the end of vect, instead of
4157 the address of the 'info' pointer itself.
4158 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
4159 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
4160 (SCM_APPLY): Explicitly allocate space for debug.vect.
4161 * debug.c (scm_m_start_stack): Same, for vframe.vect.
4162 * stacks.c: Adjusted for new debug frame structure.
4163 (RELOC_INFO, RELOC_FRAME): New macros.
4164 (stack_depth, read_frames): Use them, and new scm_debug_frame
4165 element 'info', instead of magically knowing that eval frames have
4166 an info pointer sitting after vect.
4167 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
4169 (scm_init_stacks): Formatting tweaks.
4171 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
4173 Give GCC more control flow information, so it can be sure that
4174 variables aren't used uninitialized.
4175 * error.h (scm_error, scm_syserror, scm_syserror_msg,
4176 scm_sysmissing, scm_num_overflow, scm_out_of_range,
4177 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
4178 scm_misc_error): Tell GCC that these functions never return.
4179 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
4180 out the field type, call abort if SCM_ASSERT returns, to placate
4182 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
4183 scm_wta ever returns. We can't handle this case anyway, and this
4184 gives the optimizer more information.
4185 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
4186 scm_wta ever returns.
4188 In some cases, the code is fine, but GCC isn't smart enough to
4189 figure that out; this usually happens when one variable is only
4190 initialized and used when a particular condition holds true, and
4191 we know that condition will never change within a given invocation
4192 of the function. In this case, we simply initialize the variables
4193 to placate the compiler, hopefully to a value which will cause a
4194 crash if it is ever actually used.
4195 * print.c (scm_iprin1): Initialize mw_pos.
4196 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
4197 * throw.c (scm_ithrow): Initialize dynpair.
4198 * unif.c (scm_uniform_vector_ref): Initialize cra.
4199 * struct.c (init_struct): Initialize prot.
4200 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
4202 * strports.c (scm_eval_0str): Don't return uninitialized garbage
4203 if EXPR contains no expressions.
4205 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
4207 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
4208 cause an infinite loop (???). So much for the algebraic
4209 equivalency of variable-sized arrays and alloca...
4211 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
4213 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
4214 a SCM boolean, not a C boolean.
4216 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
4218 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
4219 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
4220 rules for raising scm_mtrigger. Previously, unfortunate but not
4221 unlikely circumstances could result in almost constant invokation
4222 of the gc. Now, this situations should be less likely, but they
4223 are not prevented completely.
4225 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
4227 * numbers.c (scm_fuck): Procedure removed; looks like old test
4229 * numbers.h: Prototype removed.
4231 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
4233 * debug.h (scm_debug_frame): Change `vect' member from an in-line
4234 array to a pointer, to match my Nov 21 change in eval.c.
4236 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4238 * libguile.h: Added #include "libguile/backtrace.h", #include
4239 "libguile/stacks.h".
4241 * strings.c (scm_string scm_make_string scm_string_ref
4242 scm_string_set_x scm_string_equal_p scm_string_append):
4243 Bugfix according to scm patch from Aubrey Jaffer:
4244 Corrected long-standing
4245 (not (eqv? (integer->char 128)
4246 (string-ref (make-string 1 (integer->char 128)) 0)))
4247 bug found by John Kozak <jk@noontide.demon.co.uk>.
4249 * strports.c, strports.h: Make scm_eval_0str return the value of
4250 the last expression evaluated (previously, it returned void).
4252 * strports.c, strports.h: New function: scm_read_0str. Does what
4255 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4257 * simpos.c (scm_getenv): return #f if string can't be found in the
4258 environment instead of throwing an exception, for compatibility
4259 with numerous other systems.
4261 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
4263 * Makefile.am (.c.x): Use guile-snarf.
4264 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
4266 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
4268 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4270 * backtrace.c (scm_display_error_message): Made non-static, and
4271 renamed from display_error_message.
4272 * backtrace.h (scm_display_error_message): Added extern decl.
4273 * throw.c (uncaught_throw): Use it to display the error message.
4275 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
4277 * inet_aton.c: Use #if 0, not #ifdef 0.
4279 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
4281 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
4282 to convert the returned value.
4283 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
4284 the offset argument.
4286 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4288 Add new interface to catch/throw, usable from C as well as
4290 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
4291 (scm_internal_catch): New function, replaces...
4292 (scm_catch_apply): Deleted.
4293 * throw.c (scm_catch_apply): Deleted; replaced with a more general
4294 mechanism which is a bit more code, but can be used nicely from C
4295 and implement the Scheme semantics as well.
4296 (scm_internal_catch): This is the replacement; it's named after
4297 the analogous function in Emacs.
4298 (scm_catch): Reimplemented in terms of the above.
4299 (struct catch_body_data, catch_body, catch_handler): New
4300 functions, used by scm_catch.
4301 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
4302 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
4303 support for new cwdr.
4305 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
4308 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
4310 * acconfig.h: Added DYNAMIC_LINKING symbol.
4311 * configure.in: Add option and checks for dynamic linking.
4312 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
4313 dynl.h: New files for dynamic linking support.
4314 * Makefile.am (libguile_a_SOURCES):
4316 (modinclude_HEADERS): Added "dynl.h".
4317 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
4319 * init.c (scm_boot_guile_1): Call
4320 scm_init_dynamic_linking to initialize dynamic linking support.
4322 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
4324 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
4325 (as we Schemers say). It needs to be global, so that I can tweak
4326 it for the proper operation of unexec.
4327 (scm_boot_guile_1_live): New variable, see above.
4329 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
4331 * guile-snarf.sh: Removed.
4332 * PLUGIN/guile.libs: Added dependency for -lm.
4333 * acinclude.m4: Renamed from aclocal.m4.
4334 * PLUGIN/greet: Removed.
4335 * Makefile.am, aclocal.m4: New files.
4336 * configure.in: Updated for Automake.
4338 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
4340 * eval.c (scm_definedp): Use top_level_lookup_closure_var
4341 and not top_level_lookup_thunk_var.
4343 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
4345 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
4347 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
4349 * eval.c (scm_definedp): Incompatibly changed to be a builtin
4350 Scheme function, instead of syntax. Single argument is now a
4353 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4355 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
4356 scm_ra_divide): Properly terminate statements passed as arguments
4357 to IVDEP macros. (Thanks to Bernard Urban.)
4359 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
4360 with non-constant sizes. (Thanks to Bernard Urban.)
4362 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4364 It's an "eval closure", not an "eval thunk." A thunk is a
4365 function of no arguments.
4366 * root.h (struct scm_root_state): Renamed
4367 top_level_lookup_closure_var from top_level_lookup_thunk_var.
4368 (scm_top_level_lookup_closure_var): Renamed from
4369 scm_top_level_lookup_thunk_var.
4370 * root.c (mark_root): Uses changed.
4371 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
4372 * init.c (scm_start_stack): Uses changed.
4373 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
4374 Change scheme-visible name to *top-level-lookup-closure* from
4375 *top-level-lookup-thunk*.
4377 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
4379 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
4380 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
4382 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
4384 * gc.c (struct scm_heap_seg_data): Doc fixes.
4386 * gc.c (scm_gc_sweep): Empty all segments' freelists before
4387 sweeping. Then, prepend each segment's free cells to its
4388 freelist, rather than wiping out the old value. (Thanks to Marius
4391 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
4392 scm_check_freelist, scm_debug_newcell): New functions and
4393 variables, for debugging freelist problems.
4394 * pairs.h (SCM_NEWCELL): New debugging version added.
4395 * gc.h (scm_debug_newcell): Added extern declaration, used by
4396 debugging version of SCM_NEWCELL.
4398 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4400 On some systems <libc.h> conflicts with <unistd.h>, and should not
4401 be #included at all.
4402 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
4403 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
4404 * configure.in: Call it.
4405 * posix.c, filesys.c: Use its results to decide whether or not to
4407 * configure, scmconfig.h.in: Rebuilt with autoconf and
4410 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4412 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
4413 pointer to the stdio stream before calling scm_setbuf0, so the
4414 latter will be able to retrieve it. I'm surprised this didn't
4415 segfault earlier. (Thanks to Christopher Lee.)
4417 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4419 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
4422 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4424 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
4425 number of stack narrowing specifier pairs. The first specifier in
4426 a pair controls inner border, the second the outer border. A
4427 number means cut that number of frames, a procedure object means
4428 cut until that object is found in operator position in a frame.
4430 * root.c (cwdr): Bugfix.
4432 * read.c: Recording of positions disabled by default.
4434 * procs.c (scm_closure_p): New function.
4436 * posix.c (scm_tmpnam): New function.
4438 * load.c: Added #include "throw.h".
4439 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
4442 * load.c, load.h (scm_read_and_eval_x): New function.
4444 * eval.c: Renamed debug option "deval" to "debug".
4446 (scm_eval_x): `eval!' is no longer accessible from the scheme
4447 level. Motivation: We can't allow operations which introduce
4448 glocs into the scheme level. Guile's type system can't handle
4449 these as data. Use `eval' or `read-and-eval!' as replacement.
4451 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
4452 SCM_CONSP since this is a macro!; Set vframe.prev to
4453 scm_last_debug_frame instead of 0. In this way we can look
4454 "above" the virtual start stack frame if we wish.
4455 (scm_debug_hang): New function: Useful for debugging Guile in
4456 certain tricky situations. Will probably be removed later...
4458 * debug.h: Changed semantics of debug option "backtrace". This
4459 option now only indicates whether we want automatic backtrace at
4462 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4464 * ports.c: #include "filesys.h"
4465 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
4467 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
4468 Motivation: This is system specific code which is related to file
4469 I/O. It also may use select. Added code by Gary Houston to
4470 detect presence of character in stdio buffers.
4472 * libguile.h: #include "libguile/libpath.h"
4474 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4475 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4476 SCM_SITE_DIR; Install libpath.h among the other include files.
4478 * load.c, load.h (scm_sys_package_data_dir): New function.
4480 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4482 * stacks.h: Bugfix: Don't use tail-array length field as stack
4483 length field! This screwed GC.
4485 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4487 * _scm.h: Added #ifndef around definition of macros min and max.
4489 * __scm.h: Added hooks for threads to plugin to in ints protection
4490 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4491 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4492 the main code in these macros duplicated and spread over multiple
4493 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4494 SCM_THREAD_SWITCHING_CODE.
4496 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4498 * snarf.h: New file.
4499 * guile-snarf.sh: New file.
4500 * Makefile.in (inner_h_files): Added snarf.h
4501 (ancillary, install, uninstall, distclean): Added actions for
4503 (.c.x): Use guile-snarf.
4504 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4505 (gen_c_files): Note that these depend on guile-snarf.
4506 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4507 now in "snarf.h". Added #include "snarf.h" to get them.
4508 * libguile.h: Added #include "snarf.h".
4509 (Patches applied and tweaked by Jim Blandy.)
4511 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4513 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4514 standards suggest against providing prototypes for system
4515 functions. Thanks to Greg Troxel.
4517 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4519 * strports.c (scm_eval_0str): New function.
4520 #include "read.h", to get prototype for scm_read.
4521 * Makefile.in (strports.o): Update dependencies.
4522 * strports.h: New prototype.
4524 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4525 scheme name from "int?" to "integer?". It seems to do the job.
4526 * numbers.h: Rename prototype too.
4527 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4530 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4531 scm_num_eq_p): Rename these according to R4RS conventions: call
4532 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4533 to making libguile R4RS compliant without ice-9...
4535 * load.c (scm_sys_search_load_path): Search for files under all
4536 extensions listed in the %load-extensions variable. If FILENAME
4537 is absolute, return it unchanged, without searching the load path.
4538 (scm_loc_load_extensions): New variable, pointing to
4539 %load-extensions' value cell.
4540 (scm_init_load): Initialize it, and the value it points to.
4541 (scm_primitive_load_path): Improve error reporting.
4543 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4544 of new Scheme variable %load-hook.
4545 (scm_primitive_load): Apply %load-hook to filename.
4547 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4549 * configure.in: add tests for figuring out whether buffered data
4550 is available in a FILE structure, which is needed by char-ready.
4552 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4555 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4556 exceptions using misc_error instead of syserror. It seems a bit
4557 odd to throw an exception if a string can't be found in the
4558 environment, but it's consistent with open-file, stat etc.
4559 (simpos.h): remove sys_ from getenv.
4561 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4562 occurs, throw an error instead of returning errno. Return value
4564 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4566 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4568 * filesys.c (scm_stat2scm): derive file type and permissions from
4569 the stat mode and append them to the returned vector.
4570 There isn't much overhead in doing this and it avoids the need to
4571 work with S_IRUSR et al. in Scheme.
4572 Define symbols scm_sym_regular etc.
4573 (scm_init_filesys): don't intern S_IRUSR etc.
4575 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4576 and s_primitive_load_path.
4578 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4580 * error.h: don't declare error symbols. prototype for scm_misc_error.
4582 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4585 * error.c: use SCM_SYMBOL to set up error keys.
4586 scm_misc_error: new procedure.
4588 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4590 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4591 between `#!' and `!#' is ignored.
4592 (skip_scsh_block_comment): New function.
4594 * feature.c (scm_set_program_arguments): New argument, FIRST.
4595 * feature.h: Update prototype.
4596 * init.c (scm_boot_guile_1): Pass new argument to
4597 scm_set_program_arguments.
4599 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4601 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4602 (scm_boot_guile): Call scm_set_program_arguments here, later than
4603 the old initialization.
4605 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4606 initialization procedure.
4607 - Delete in, out, err arguments; there are other perfectly good
4608 ways to override these when desired.
4609 - Delete result argument; this function shouldn't ever return.
4610 - Rename init_func argument to main_func, for less confusion.
4611 - Delete boot_cmd argument; main_func is more general.
4612 -Add 'closure' argument, to help people pass data to main_func
4613 without resorting to global variables.
4614 - Abort if reentered; don't bother returning an error code.
4615 - Call scm_init_standard_ports to set up the default/current
4616 standard ports; no need to pass them to scm_start_stack.
4617 - Remove code to evaluate the boot_cmd, and start the repl; let
4618 the user do something like that in main_func if they want.
4619 - Remove code to package up a return value; main_func can do any
4621 - Call exit (0), instead of returning.
4622 (scm_start_stack): Don't initialize the I/O ports here; that's
4623 weird. Delete in, out, err arguments. Move guts to
4624 scm_init_standard_ports, scm_stdio_to_port.
4625 (scm_init_standard_ports): New function, to set up current and
4626 default standard ports.
4627 (scm_start_stack, scm_restart_stack): Make these static.
4628 * init.h (scm_boot_guile): Adjust declaration.
4629 (scm_start_stack, scm_restart_stack): Remove externally
4630 visible declarations for these.
4631 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4633 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4634 written out several times in scm_start_stack.
4635 * fports.h: New declaration for the above.
4637 * feature.c (scm_set_program_arguments): New function.
4638 * feature.h: New declaration for the above.
4640 * ports.c: Formatting tweak.
4642 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4644 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4645 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4646 for obtaining the address of a car or cdr field. Motivation:
4647 &SCM_CXR make assumptions about the internal structure of the
4650 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4651 Motivation: see SCM_CXRLOC.
4653 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4654 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4655 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4656 Motivation: Safer use. Some other macros are defined in terms of
4657 these operations. If these are defined using the SCM_SETCXR
4658 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4659 to inefficiency and an <e1> with side-effects could potentially
4660 break. Also, these particular operations are heavily utilized in
4661 the garbage collector. In unoptimized code there will be a
4664 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4665 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4666 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4667 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4668 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4669 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4670 vports.c: Cleaned up use of pairs: Don't make any special
4671 assumptions about the internal structure of selectors and
4672 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4673 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4674 (Among other things, this change makes it easier to build Guile
4675 with certain compilers which have problems with casted lvalues.)
4677 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4679 * stacks.c: Improve selection of relevant stack frames when making
4680 a stack object. Introduce one level of indirection in the stack
4681 object to make it possible to "narrow" to a certain region of the
4682 stack. This facilitates making use of more clever algorithms (not
4683 implemented) for selecting relevant frames and gives a cleaner
4684 design since selection of frames can be done independently of
4685 extraction of frames from the real stack.
4686 (scm_stack_id): Also take #t as argument which means look at
4689 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4690 Turn n_tail into an integer directly representing current number
4691 of frames in stack. Add field tail.
4693 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4695 * debug.c (scm_make_memoized): Made it available at scheme level.
4696 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4697 SCM_NIMP before applying heavier predicates in argument checking.
4698 (scm_local_eval): Also take memoized object as argument.
4700 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4701 aren't created with zero length, but should such a strange
4702 creature suddenly turn up...
4704 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4706 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4707 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4709 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4711 * variable.c (scm_make_variable): Make the name hint optional, as
4713 (anonymous_variable_sym): Renamed from variable_sym. All uses
4716 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4717 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4718 of scm_primitive_load_path was also changed to
4719 "primitive-load-path", from "%try-load-path". Callers changed.
4720 We'd like to respect the convention that a function named
4721 "try-mumble" should behave just like the function called "mumble",
4722 but return #f instead of signalling some error.
4723 * load.h: Rename prototypes.
4725 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4727 * print.c (make_print_state, grow_print_state), print.h: Modified
4728 the print state representation: Don't use a tail array for
4729 recording of circular references. Resizing of the print state
4730 structure invalidates the print state pointer. To avoid passing
4731 around an indirect print state reference to all printing
4732 functions, we instead let the print state reference a resizable
4735 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4737 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4738 Don't crash when passed an improper list terminated by a
4739 non-immediate value.
4741 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4743 Allocate data for structures on an eight-byte boundary, as
4744 required by the tagging system.
4745 * struct.c (alloc_struct): New function.
4746 (scm_make_struct, scm_make_vtable_vtable): Call it.
4747 * struct.h (scm_struct_n_extra_words): Bump to 3.
4748 (scm_struct_i_ptr): New "field".
4749 * gc.c (scm_gc_sweep): When we need to free the data, use the
4750 information stored by alloc_struct to find the beginning of the
4751 block allocated to the structure, so we can free it.
4753 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4755 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4758 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4759 (scm_debug_info): New member: id.
4761 * stacks.c: Stacks are now represented as structs; Stacks have an
4762 id given to them by `start-stack'.
4763 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4765 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4766 Changed stack representation.
4768 * debug.c (scm_procedure_name): Try procedure property `name' for
4769 compiled closures aswell.
4771 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4773 * eval.c: scm_i_name moved to gsubr.c
4774 (scm_m_define): Record names of all kinds of procedure
4775 objects. (Earlier, only closures were recorded.)
4777 * procprop.h: Added declaration of scm_i_name.
4779 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4780 (scm_make_gsubr): Record names of compiled closures.
4782 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4784 * debug.c, debug.h: Removed obsolete code.
4786 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4787 stacks.c: Renamed regs --> scm_contregs.
4789 * print.c (scm_free_print_state): Cleanup print state before
4790 returning it to pool. It is better to do it here than in
4791 scm_prin1 since scm_prin1 is called often.
4793 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4794 s_set_source_property_x): Check that first argument is a pair or a
4797 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4798 scm_i_line, scm_i_column and scm_i_breakpoint global.
4800 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4801 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4804 * debug.h: Added debug object smob declaration and macro
4807 * configure.in: Build with backtrace.o and stacks.o if debug
4810 * Makefile.in: Added entries for new files: backtrace.c,
4811 backtrace.h, stacks.c and stacks.h.
4813 * symbols.c (scm_sym2ovcell): Fixed documentation.
4815 * _scm.h (min, max): Added.
4817 * async.c: Moved `min' macro to _scm.h.
4819 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4820 SCM_BACKTRACE_INDENT.
4822 * eval.c: Added new debug options `maxdepth' and `indent'.
4824 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4826 * print.h: Added selector SCM_PRINT_STATE.
4828 * print.c: New functions: scm_make_print_state,
4829 scm_free_print_state.
4831 * print.h: Added declarations for scm_make_print_state,
4832 scm_free_print_state.
4834 * debug.c (scm_m_start_stack): New acro.
4836 * debug.h: Small cleanup.
4838 * init.c (scm_boot_guile_1): Moved scm_init_debug below

4863 declare functions with prototypes. (Patch thanks to Marius
4866 More prototype-related changes from Marius Vollmer:
4867 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4868 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4869 * ports.h (ptobfuns): Added prototypes. This means some casting in
4871 * fports.c: Added casts for initializations, since the functions
4872 are defined to take FILE * as their stream argument, not SCM.
4873 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4874 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4875 to `char *str_data' to conform to prototype.
4877 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4879 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4881 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4883 * stime.c, stime.h: use SCM_P method.
4885 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4887 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4888 be given at least two arguments. Insist that lst's last element
4889 be a list, but don't make any requirements of its predecessors.
4891 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4893 * eval.c (scm_nconc2last): Revert last change; there seems to be
4894 other stuff going on here.
4896 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4898 * eval.c (scm_nconc2last): Make sure that each element of lst
4899 (which is a list of argument lists, except for the tail) is a
4900 proper list, i.e., finite and terminated by '().
4902 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4904 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4907 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4908 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4911 * vectors.c (scm_make_vector): Fill vectors with the undefined
4912 value, to help make Guile Scheme code more portable to other
4915 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4916 * symbols.h, tags.h: Doc fixes.
4918 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4920 * async.c (scm_take_signal): Doc fixes.
4922 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4924 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4925 want to subtract it from the modulus; we just want to leave it
4928 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4930 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4933 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4935 * throw.c (scm_catch_apply): Finished implementation of
4938 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4940 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4942 (scm_init_filesys): set "i/o-extensions" feature.
4945 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4947 * Makefile.in (root.o): Correct dependencies.
4949 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4951 * Makefile.in: Added dependency entry for root.o.
4953 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4954 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4956 * init.c (scm_start_stack): Set initial root continuation number
4959 * procs.c: New function: scm_thunk_p.
4961 * procs.h: Added declarations of scm_thunk_p.
4963 * root.c: Renamed `call-with-new-root' -->
4964 `call-with-dynamic-root'.
4965 (cwdr): Removed allocation of new root state. This should be done
4966 separately by use of scm_make_root.
4967 (scm_apply_with_dynamic_root): New function: Does what it
4968 sounds like. Needed when spawning threads.
4970 * root.h: Added member last_debug_frame to root state.
4971 Added #include "libguile/debug.h"
4973 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4974 arguments. The motivation is that code in root.c needs catch
4975 functionality, and we want to avoid code duplication.
4976 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4977 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4978 handlers that run without popping the stack into the dynwind
4981 * throw.h: Added prototypes for scm_catch_apply and
4984 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4986 * root.h (scm_root, scm_set_root): Decouple thread support details
4987 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4988 SCM_SET_THREAD_LOCAL_DATA.
4990 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4991 and tortoise scanning loop.
4993 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4995 * Makefile.in: Rebuild dependencies.
4997 * libguile.h: #include "libguile/print.h" before "smob.h", since
4998 the latter uses the print_state structure.
5000 * throw.c (scm_ithrow): Use the correct variable when checking to
5001 see if a given element of scm_dynwinds is a valid catch.
5003 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
5004 structure, abort; don't just silently ignore the garbage.
5006 * _scm.h: #include "print.h" here, since it seems to be used just
5008 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
5009 strports.c, unif.h: Don't #include "print.h".
5011 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5013 * feature.h (scm_loc_features): Removed external declaration.
5014 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
5016 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5018 * feature.c (scm_init_feature): Added threads feature (needs to be
5019 initialized here, since features doesn't exist when
5020 scm_init_threads is called).
5022 * libguile.h: Added #include "libguile/../threads/threads.h".
5023 (This is a kludge to get thread support working. This should be
5026 * configure.in, acconfig.h: Added flags for thread support.
5028 * scmsigs.c: Define `signal' to be `pthread_signal' if using
5031 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
5032 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
5035 * _scm.h: Added conditional #include "threads.h"
5037 * __scm.h (SCM_ASYNC_TICK): Added call to macro
5038 SCM_THREADS_SWITCHING_CODE.
5040 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
5041 allocate the basic dynamic root object.
5042 (scm_boot_guile): Added call to scm_init_root.
5044 * root.c, root.h: Added root smob.
5045 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
5046 functions: Implements dynamic roots mostly according to spec in
5047 SCM manual. Main difference is that the second argument is a
5048 throw handler rather than an error "thunk".
5050 * root.h: Added declaration of scm_init_root.
5052 * root.c: Added #include "genio.h", #include "smob.h", #include
5053 "pairs.h", #include "throw.h", #include "dynwind.h", #include
5055 (scm_init_root): Added #include "root.x".
5057 * throw.c: Added #include "stackchk.h"
5058 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
5059 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
5060 can be used in scm_call_with_new_root; Added reenabling of stack
5061 checking when catching a throw.
5063 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
5065 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
5067 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
5068 element is not found, as per R4RS.
5070 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
5072 * list.c: Doc fixes throughout.
5074 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
5076 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
5077 declare the char * to be const. Avoids a warning in rgx.c.
5079 * ports.h: spelling fix.
5081 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
5084 * load.c (scm_sys_try_load_path): throw an error if file not found
5085 (like it says it in NEWS).
5087 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
5089 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
5090 PROPS slot to '(), not #f; it's an empty alist.
5092 * throw.h, throw.c: Use SCM_P instead of #if hair.
5094 Remove special support for uncaught throws; see throw.c for
5096 * throw.c (uncaught_throw): New function.
5097 (scm_ithrow): Call uncaught_throw if we don't find a throw
5098 target; don't mess with scm_bad_throw_vcell.
5099 (scm_bad_throw_vcell): Variable deleted.
5100 (scm_init_throw): Don't initialize it.
5102 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
5105 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
5107 * numbers.c (scm_istr2int): If the number is short (as most
5108 numbers are), just call scm_small_istr2int to deal with it.
5109 (scm_small_istr2int): New function, created by un-#ifdefing the
5110 non-bignum version of scm_istr2int and renaming it.
5112 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
5114 * load.c (scm_sys_try_load): don't check whether value returned
5115 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
5116 Change the Scheme name from %try-load to primitive-load.
5118 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
5119 Can avoid passing a message, allowing it to be derived in the
5120 error handler (e.g., if we want to throw to the key both from
5123 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
5125 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
5126 references now have a new appearance which is more compact and
5127 also gives a clue about what the target of the reference is.
5128 By setting parameters in the print state, more fancy printing can
5129 be achieved. This is used by the (not yet commited) backtrace
5132 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
5134 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
5137 * print.c: Added #include "struct.h". Removed function
5140 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
5141 scm_iprin1. Removed prototype for scm_prlist.
5143 * arbiters.c (prinarb),
5144 async.c (print_async),
5145 debug.c (prindebugobj, prinmemoized),
5146 eval.c (prinprom, prinmacro),
5147 filesys.c (scm_fd_print, scm_dir_print),
5149 mallocs.c (prinmalloc),
5150 numbers.c, numbers.h (scm_floprint, scm_bigprint),
5151 smob.h (scm_smobfuns),
5152 srcprop.c (prinsrcprops),
5154 unif.c, unif.h (scm_raprin1, rapr1),
5155 variable.c (prin_var): Changed argument `int writing' to
5156 `scm_print_state *pstate'.
5158 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
5159 that it will be called before scm_init_print.
5161 * print.c (scm_prin1): Print states are now allocated when calling
5162 scm_prin1 and then passed around to all printing functions as an
5163 argument. A cache `print_state_pool' enables reuse of print
5165 (scm_make_print_state): New function.
5166 (scm_iprin1): Adaption to print states.
5167 (scm_iprlist): An initial "hare and tortoise" scan brings down
5168 time complexity to O (depth * N). (Better time complexity will be
5169 achieved when the printing code is completely rewritten.)
5171 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
5173 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
5174 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
5175 it gets done whether or not the cache variable has a value.
5177 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5179 Distinguish #f and ().
5180 * __scm.h: #undef SICP.
5181 * pairs.h (SCM_EOL): Delete this definition, equating it with
5183 * tags.h (SCM_EOL): Give it a new definition here; I think I found
5184 the value it used to have. Doc fixes, too.
5186 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
5188 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
5189 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
5190 Lord's implementation of structs, allowing for tail arrays as
5191 described in the manual. Also fixed some bugs. (Both the interface
5192 and the implementation should be improved.)
5194 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
5196 * print.c, print.h: Closures now print like #<procedure foo (x)>.
5197 People who whish to see the source can do `(print-enable 'source)'.
5198 Removed #ifdef DEBUG_EXTENSIONS.
5200 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5202 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
5203 integer (assuming for now accepting an integer is a good thing).
5205 * error.c, fports.c: replace use of %S in lgh_error args with %s.
5206 %S will be used instead for write'ing arguments.
5208 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
5209 asserts. fix a few other asserts.
5210 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
5211 scm_uniform_vector_ref, scm_array_set_x,
5212 scm_dimensions_to_unform_array): change args in
5213 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
5214 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
5215 scm_substring_fill_x): likewise.
5216 gsubr.c (scm_gsubr_apply): likewise.
5217 eval.c (SCM_APPLY): likewise.
5219 * eval.c (4 places): replace scm_everr with lgh_error or
5222 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
5223 scm_memory_error): new procedures.
5224 scm_everr: deleted. can use scm_wta, dropping first two args.
5225 scm_error: convert NULL subr to SCM_BOOL_F.
5227 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
5230 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
5233 * error.c, error.h: new error keys: scm_arg_type_key,
5234 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
5236 scm_wta: reimplement using lgh_error instead of scm_everr.
5238 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
5240 * gdbint.c: scm_lread now has one more argument.
5242 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
5243 scm_port_\1; Added mutator scm_set_port_filename_x (used when
5244 loading source from non-file ports, which, e. g., happens when
5245 using the Emacs interface).
5247 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
5250 * read.c: Added code for recording of positions of source code
5251 expressions; New functions: recsexpr, scm_lreadrecparen;
5252 _scm_make_srcprops --> scm_make_srcprops
5253 (scm_flush_ws): Removed updating of positions counters. This work
5254 is already done by scm_gen_getc
5256 * read.h: Added prototype for scm_lreadrecparen
5258 * print.c: Added #include "alist.h"
5260 * eval.c: Added #include "hash.h"
5262 * eq.c: Added #include "ramap.h"
5264 * options.c: Documentation fixes.
5266 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
5267 (scm_init_srcprop): Adjusted size of initial source-whash. Name
5268 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
5269 --> scm_make_srcprops
5271 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
5272 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
5273 function calls in the definition of the whash access macros.
5275 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
5277 * init.c (scm_boot_guile): Add level of indirection to
5278 scm_boot_guile_1() to ensure that stack base pointer is properly
5279 initialized. There was no guarantee that variable i was the
5280 highest/lowest variable on stack (i.e. the call frame of
5281 scm_boot_guile was not completely protected from gc).
5283 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
5285 * ports.h (scm_port_table): put back file_name, it will be used to
5286 support debugging. Undo related changes in fports.c, ioext.c,
5289 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5291 * ports.h (scm_port_table): remove file_name member for now, it seems
5293 * fports.c (scm_open_file): don't set file_name in PTAB.
5294 (prinfport): don't use file_name in PTAB.
5295 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
5296 * ports.c (scm_add_to_port_table): don't intialize file_name.
5297 (scm_port_file_name): remove for now.
5298 * gc.c (scm_gc_mark): don't mark PTAB file_name.
5300 * fports.h (scm_mkfile): prototype deleted.
5301 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
5303 * debug.c, unif.c: use scm_out_of_range instead of
5304 wta for range errors (ASSERT still needs work).
5306 * error.c, error.h (scm_out_of_range): new procedure.
5308 * error.c, error.h (scm_out_of_range_key): new key.
5310 * posix.c (scm_sync): #else was missing.
5312 * error.c, error.h: append _key to names scm_num_overflow and
5315 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
5316 of consing an empty list.
5317 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
5318 of macros, saves code and string space.
5319 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
5320 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
5321 lower case. Rename scm_syserror_m to scm_syserror_msg.
5322 error.h: prototypes for new procedures.
5324 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
5326 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
5328 * error.c, error.h: setup scm_num_overflow key.
5330 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
5331 Remove definition of SCM_OVSCM_FLOW.
5333 * fports.c (scm_open_file): use SCM_SYSERROR_M.
5335 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
5336 explicit message and args.
5338 * error.c, error.h, __scm.h: change system_error_sym to
5341 * error.c (system_error_sym): remove leading %% from the Scheme name
5344 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
5346 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5348 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
5349 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
5350 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
5351 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
5352 renamed. (These were introduced by unsupervised name
5355 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5357 * print.c: Added code for detection of circular references during
5358 printing. (init_ref_stack, grow_ref_stack): New functions. Added
5359 a hook for printing of closures (accessible via print options).
5360 This leads to a split of calls to scm_iprin1 into two classes:
5361 elementary print operations (e. g. the code which prints a smob)
5362 still use scm_iprin1 while top level calls (like scm_display) use
5363 scm_prin1. scm_prin1 begins by clearing the data structure used
5364 to record reference information.
5366 * print.h: Added declarations of scm_prin1 and scm_prlist.
5368 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
5370 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
5372 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
5374 * error.c (err_head): scm_iprin1 --> scm_prin1
5376 * debug.c: Adjusted header comment.
5380 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
5382 * strerror.c: Doc fix.
5384 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5386 * gdbint.c (gdb_read): Now possible to run during GC.
5387 (unmark_port, remark_port): New functions.
5389 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
5391 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
5392 of allocating a new string object. Also, increase size by
5393 the factor 2 instead of 1.5.
5395 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
5397 * __scm.h (SCM_P): Corrected to run under traditional C.
5399 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
5402 * async.c: Calls to scm_sysintern corrected.
5404 * async.h (scm_async_clock): Redundant declaration removed.
5406 * continuations.c (scm_dynthrow): Redundant declaration removed.
5408 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
5409 Definition typos corrected.
5411 * debug.h: Missing declarations of functions in debug.c added
5414 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
5415 Missing declarations to functions in eval.c added.
5417 * filesys.c: Possibly uninitialized variable rv.
5419 * gc.h (scm_object_addr, scm_unhash_name): Missing
5420 declarations of functions defined in gc.c added.
5422 * genio.c: Possible typos str_data -> wstr_data. ???
5424 * genio.c: Possibly unintended shadowing of local variable
5425 `int c' (gotos out of scope of inner `c'). ???
5427 * init.c: Uninitialized `SCM last' may be used.
5429 * ioext.h: (scm_sys_isatty_p): Typo.
5431 * list.h (scm_list_head): Missing prototype for function in
5434 * numbers.c (scm_two_doubles): Changed from extern to static
5435 (is used only within numbers.c).
5437 * numbers.h: Repeated declarations removed.
5439 * ports.h (scm_close_all_ports_except): Declaration for the
5440 function defined in ports.c added.
5442 * posix.h: Missing declarations added.
5444 * procs.h (scm_make_subr_opt): Missing declaration added.
5446 * socket.h (scm_sys_gethost): Missing declaration added.
5448 * socket.h: Redundant declarations removed (they are in fdsocket.h).
5450 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
5451 Missing declarations added.
5453 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
5455 * struct.c: Uninitialized variable `SCM answer' may be used.
5457 * unif.c (l2ra): Declaration prototype.
5459 * unif.c (scm_array_equal_p): Dummy definition removed (it is
5460 defined in ramap.c).
5462 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
5463 Redundant declarations removed (they are in ramap.h).
5465 * variable.h (scm_make_udvariable,
5466 scm_make_undefined_variable): Declaration corrected to
5467 correspond variable.c.
5469 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
5470 Missing declarations added.
5472 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5474 * Makefile.in (distclean): Don't forget to delete fd.h.
5476 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5478 * fd.h.in, tags.h: Trivial cleanups.
5480 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5481 marksweep.h just declared functions from gc.c.
5482 * gc.h, libguile.h: Don't #include "marksweep.h".
5483 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5484 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5485 dependencies updated.
5487 * libguile.h: Don't #include "files.h"; it's been deleted.
5489 * files.c (scm_sys_delete_file): Moved to filesys.c.
5490 File is now empty; deleted.
5492 * filesys.c: scm_sys_delete_file is now here. Remove
5493 #if's; they seem to rely on remnants of an old portability
5494 regimen. If the problems come up again, solve them properly,
5495 using autoconf. Specifically: Don't test M_SYSV, and #define
5496 remove to be unlink if it's #defined; don't use remove just
5497 because HAVE_STDC_HEADERS is #defined.
5498 * filesys.h: Add declarations for scm_sys_delete_file.
5499 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5500 files.o, files.h, files.c, and files.x.
5501 * init.c: Don't #include "files.h", and don't call scm_init_files.
5503 Use SCM_P instead of PROTO; the latter intrudes on the user's
5505 * params.h: Deleted; definition of SCM_P moved to...
5506 * __scm.h: ... here, where it replaces PROTO macro.
5507 * libguile.h, smob.h: Don't #include "params.h".
5508 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5509 smob.h: Fix prototypes accordingly.
5510 * Makefile.in: Update dependencies.
5511 (inner_h_files): Remove params.h.
5513 * gc.c: #include "gc.h"; every module should include its header,
5514 to let the compiler cross-check the declarations against the
5517 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5518 simpos.h: #include "libguile/__scm.h".
5520 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5522 * init.c: Don't forget to #include smob.h and init.h.
5523 * Makefile.in: Dependencies updated.
5525 * smob.h: Use PROTO instead of #if __STDC__.
5527 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5529 * __scm.h: Doc fixes.
5531 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5532 <angles>; this allows `make depends' to work properly.
5534 * libguile.h: #include smob.h and pairs.h before the others; they
5535 define typedefs used by other headers.
5537 C files should #include only the header files they need, not
5538 libguile.h (which #includes all the header files); the pointless
5539 recompilation was wasting my time.
5540 * Makefile.in (all .o dependency lists): Regenerated.
5541 * libguile.h: Don't try to get a definition for size_t here...
5542 * __scm.h: Do it here.
5543 * _scm.h: Since this is the internal libguile header, put things
5544 here that all (or a majority) of the libguile files will want.
5545 Don't #include <libguile.h> here; that generates dependencies on
5546 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5547 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5548 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5645 * weaks.c: Get "weaks.h".
5647 * stackchk.h: #include "libguile/debug.h",
5649 * print.h, read.h: #include "options.h", since everyone who uses
5650 either of these files will need that.
5652 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5653 anyone who uses this file will need them to define the smob
5654 printing functions. Also, get markers.h, since people will need
5655 to #define the mark functions.
5657 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5658 * ports.h: ... to here.
5660 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5661 don't rely on archaic C default type rules.
5663 * fports.h: #include "libguile/ports.h", since you need that in
5664 order to parse this.
5666 * genio.h: #include "libguile/print.h", because you need that to
5667 parse this; don't bother #including "ports.h", since print.h gets
5670 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5672 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5673 this; it's now a reference to an element of *scm_root.
5675 * debug.h: Don't #include "options.h"; the compiler won't be able
5676 to find that once the headers are installed; instead, #include
5677 "libguile/options.h".
5678 * gc.h: Same, with marksweep.h.
5679 * mbstrings.h: Same, with symbols.h.
5680 * scmhob.h: Same, with _scm.h.
5681 * smob.h: Same, with params.h.
5683 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5684 C files; there's no need for this, and it forces recompilations
5687 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5689 * error.c (scm_error): declare scm_error_callback.
5691 * error.h: prototype for scm_error_callback.
5693 * __scm.h: define lgh_error.
5694 (SCM_SYSERROR): redefine using lgh_error.
5696 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5698 * error.c (scm_error): new procedure.
5700 * error.h: prototype for scm_error.
5702 * Makefile.in (install): install scmconfig.h from the current
5703 directory, not $(srcdir).
5705 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5707 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5708 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5709 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

5715 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5716 vports.h, weaks.h: #include "libguile/__scm.h", not
5717 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5718 dependencies are within libguile properly.
5720 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5722 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5723 when scmconfig.h doesn't exist.
5725 * load.c (scm_sys_try_load): Correct spelling.
5727 * feature.c (scm_loc_features): Make this static.
5729 * Makefile.in (libpath.h): Omit trailing slash from path. We
5730 shouldn't require it of users, so why put it here?
5732 Move code to initialize and search %load-path from ice-9 to C
5733 code, so we can use the load-path to find the ice-9 boot code;
5734 this makes it easier to run Guile without installing it. See
5735 corresponding changes in guile/Makefile.in.
5736 * feature.c: Move stuff concerned with the load path to load.c.
5737 (scm_compiled_library_path): Deleted.
5738 Don't #include libpath.h here.
5739 * feature.h: Don't mention scm_compiled_library_path.
5740 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5741 <sys/stat.h>, and <unistd.h> (if present).
5742 (R_OK): #define if the system hasn't deigned to.
5743 (scm_loc_load_path): New variable.
5744 (scm_init_load_path, scm_sys_search_load_path,
5745 scm_sys_try_load_path): New functions.
5746 (scm_init_load): Initialize scm_loc_load_path to point to the
5747 value cell of the Scheme %load-path variable.
5748 * load.h: Add declarations for scm_sys_search_load_path,
5749 scm_sys_try_load_path.
5750 * init.c: Call scm_init_load_path.
5751 * Makefile.in (feature.o, load.o): Dependencies updated.
5753 * load.c, load.h: Rewrite using PROTO macro.
5755 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5757 * gc.c (scm_cellp): New function: C predicate to determine if an
5758 SCM value can be regarded as a pointer to a cell on the heap.
5760 * gc.h: Added declaration of scm_cellp.
5762 * gdb_interface.h: New file: The GDB interface header from the GDB
5765 * gdbint.c: New file: GDB interface.
5767 * gdbint.h: New file: GDB interface.
5769 * libguile.h: Added #include <libguile/gdbint.h>.
5771 * init.c (scm_boot_guile): Added scm_init_gdbint.
5773 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5774 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5775 found if object files and source are kept separate).
5777 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5779 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5781 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5783 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5784 TK_SRC_DIR; they're not relevant any more.
5786 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5787 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5789 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5791 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5792 search path, so we can find the <libguile/MUMBLE.h> headers.
5794 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5796 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5797 implicit in the .c.o rule.
5798 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5801 Put the library path in a header file, instead of passing it on
5802 the command line in every compilation.
5803 * Makefile.in (libpath.h): New target.
5804 (feature.o): Depend on libpath.h.
5805 (clean): Delete libpath.h.
5806 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5807 * feature.c: ... #include "libpath.h" here.
5808 * .cvsignore: Ignore libpath.h.
5810 Don't install the unwashed masses of Guile header files in the
5811 main #include path; put most of them in a subdirectory called
5812 'libguile'. This avoids naming conflicts between Guile header
5813 files and system header files (of which there were a few).
5814 * Makefile.in (pkgincludedir): Deleted.
5815 (innerincludedir): New variable; this and $(includedir) are enough.
5816 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5817 (installed_h_files): Divide this up. Now this variable lists
5818 those header files which should go into $(includedir) (i.e. appear
5819 directly in the #include path), and ...
5820 (inner_h_files): ... this new variable says which files appear in
5821 a subdirectory, and are referred to as <libguile/mumble.h>.
5822 (h_files): List them both.
5823 (install): Create innerincludedir, not pkgincludedir. Put
5824 the installed_h_files and inner_h_files in their proper places.
5825 (uninstall): Corresponding changes.
5826 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5827 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5828 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5829 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5830 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5831 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5832 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5833 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5834 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5835 vports.h, weaks.h: Find __scm.h in its new location.
5836 * __scm.h: Find scmconfig.h and tags.h in their new locations
5837 (they're both "inner" files).
5839 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5841 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5843 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5845 * posix.c: Doc fixes.
5847 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5849 * socket.c: Don't include a prototype for inet_aton; just use a
5850 K&R style declaration, to avoid warnings but minimize the chance
5851 of conflicts with the system.
5853 On NextStep, <utime.h> doesn't define struct utime, unless we
5854 #define _POSIX_SOURCE before #including it.
5855 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5856 * acconfig.h: New comment text for above CPP symbol.
5857 * configure.in: Call it.
5858 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5860 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5862 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5863 testing for __EMX__.
5865 * posix.c: #include <libc.h>, if it exists.
5867 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5868 don't even know if the latter exists.
5870 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5871 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5872 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5874 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5876 (scm_init_posix): Use them when initializing the Scheme constants
5879 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5881 * Makefile.in (libdir, includedir, bindir): Use the
5882 autoconf-supplied values, instead of deriving them ourselves.
5883 (pkgincludedir, datadir, pkgdatadir): New variables.
5884 (install, uninstall): Put the header files in a special
5885 subdirectory, not in the main search path.
5887 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5888 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5890 * Makefile.in (IMPLPATH): Deleted; never used.
5892 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5893 on the Tcl/Tk source any more.
5894 (INCLUDE_CFLAGS): Remove references to the above.
5896 * Makefile.in (version.o): Corrected dependencies.
5898 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5900 * libguile.h: #include "version.h"
5902 * init.c (scm_boot_guile): Call scm_init_version.
5903 * gscm.c (gscm_run_scm): Call scm_init_version.
5905 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5906 GUILE_VERSION): AC_DEFINE these.
5907 (acconfig.h): #undef the above symbols.
5909 * Makefile.in (libobjs): Add version.o.
5910 (installed_h_files): Add version.h.
5911 (c_files): Add version.c.
5912 (gen_c_files): Add version.x.
5913 (version.o): New rule.
5914 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5915 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
5916 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
5917 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
5918 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
5919 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
5920 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
5921 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
5922 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
5923 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5924 weaks.o): Add version.h to dependency lists.
5925 (markers.o): Remove duplicate rule.
5927 * version.h: New file.
5929 * version.c: New file.
5931 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5933 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5934 array; use it appropriately. Since GCC is quite happy to
5935 subscript functions, it never warned us about this; we should use
5936 -Wpointer-arith in the future. I guess we never tested
5939 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5941 * socket.c: Doc and copyright fixes.
5943 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5945 * debug.c: Fixed and improved gdb support.
5947 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5949 * socket.c: Added declaration of inet_aton to avoid compiler
5950 warning. (Hope this solution is correct.)
5952 * stime.c: Added declaration of ftime. (This is missing in
5955 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5957 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5959 * Makefile.in (c_files): add strerror.c.
5961 * strerror.c: new file from Emacs' sysdep.c.
5962 maybe configure should also check for sys_errlist.
5964 * configure.in (AC_REPLACE_FUNCS): add strerror.
5966 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5968 * debug.c (scm_init_debug): Added initialization for
5969 scm_evaluator_traps.
5971 * debug.h, debug.c: Various name changes.
5972 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5973 "debug-options-interface". See commentary in options.c.
5975 * options.h, options.c: Options now have documentation strings.
5976 Also added a long explanatory commentary.
5978 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5981 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5982 last_debug_info_frame is now updated in all cases.
5984 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5987 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5989 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5990 Added option STACK_CHECKING.
5992 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5994 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5996 * __scm.h: Removed symbols for debugging support.
5998 * acconfig.h: Added symbols for debugging support.
6000 * configure.in: Added user option for debugging support.
6001 --enable-debug will include the debugging code into libguile.a.
6003 * continuations.c (scm_make_cont): Enlarged the #if 0 around
6004 scm_relocate_chunk_to_heap.
6006 * debug.c: New file: low-level debugging support. It also
6007 includes support for debugging with gdb. (The extensions to gdb
6008 are written by Per Bothner at Cygnus.)
6010 * debug.h: New file: low-level debugging support.
6012 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
6013 argument pairs. Extensive modifications to the debugging
6014 evaluator. Added "SECTION:" commentaries to clarify what happens
6015 when, during double compilation. Renamed EVALIMP --> EVALIM.
6016 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
6017 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
6018 the beginning of the file. New procedure: scm_unmemocopy.
6019 Added some global state variables needed by the debugging
6020 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
6021 check_entry, check_apply, check_exit, debug_options and
6022 evaluator_traps. New acro: undefine.
6024 * eval.h: Renamed EVAL --> XEVAL.
6026 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
6027 --> scm_make_weak_key_hash_table.
6029 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
6030 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
6032 * libguile.h: Conditionally include debug.h
6034 * objprop.c (scm_object_properties, scm_set_object_properties_x):
6035 scm_object_properties shouldn't return handle. `handle' now gets
6036 initialized in scm_set_object_properties_x. scm_object_properties
6037 doesn't any longer create an entry in scm_object_whash.
6039 * options.c: New file: handling of run time options.
6041 * options.h: New file: handling of run time options.
6043 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
6045 * print.c: New procedure: scm_print_options
6047 * print.h: Defines for print options.
6049 * read.c: New procedure: scm_read_options
6051 * read.h: Defines for reader options.
6053 * root.h: Added scm_source_whash among scm_sys_protects.
6055 * srcprop.c: New file: source properties.
6057 * srcprop.h: New file: source properties.
6059 * throw.c (jbsmob): Jump buffers are now correctly allocated.
6060 (Bug found by A. Green.)
6062 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
6064 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
6066 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
6068 * libguile.h: #include "objprop.h"; I guess this was forgotten.
6070 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
6071 and should be called by the final client.
6073 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
6075 * gc.h: Use the PROTO macro when declaring functions.
6076 * gc.c: Use the PROTO macro when declaring static functions.
6077 Remove the CPP hair around function definitions.
6079 * gc.c (scm_init_storage): Initialize scm_asyncs.
6081 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
6082 preprocessor symbol; "__scm.h" is where it might get #defined.
6083 * __scm.h: Similar: #include <scmconfig.h> before testing
6086 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
6088 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
6090 * init.c (scm_boot_guile): Add init_func argument; call
6091 (*init_func) instead of calling scm_appinit; it's ucky to
6092 hard-code names for the user's procedures.
6093 * init.h (scm_boot_guile): Adjust declaration.
6095 * __scm.h (PROTO): New macro, for declaring functions with
6098 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
6099 eliminate all the __STDC__ conditionals.
6100 (scm_boot_guile): Add declaration.
6101 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
6102 Remove __STDC__ conditionals around function definitions; the
6103 declarations in init.h will provide the same information, more
6106 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
6107 complain about it in the error message; the error message is
6108 adequate without that note, and there's nothing the user can do
6111 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
6113 * Makefile.in (ancillary): Drop def.sed.
6115 * posix.c (scm_init_posix): Use numeric values, rather than
6116 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
6117 F_OK. The symbols aren't available on some systems, and I'm
6118 pretty sure their values are fixed by common widespread practice.
6119 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
6121 More functions unavailable on some systems.
6122 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
6123 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
6125 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
6126 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
6127 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
6128 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
6129 stub that signals an error as the #else.
6131 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
6133 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
6135 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
6137 * unif.c: include ramap.h.
6139 * read.c (endif): case_insensative_p renamed case_insensitive_p.
6141 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
6143 * ports.c: include sys/ioctl.h.
6145 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
6147 * configure.in: check for sys/ioctl.h.
6149 * ports.c: include <malloc.h> not "malloc.h".
6151 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6153 * fports.c: remove ttyname and tmpnam declarations.
6155 * posix.c: fewer ttyname declarations.
6157 * fports.c: include <string.h> not "string.h".
6159 * init.c, ioext.c: include string.h and unistd.h.
6161 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6163 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
6164 genio.c, simpos.c, vports.c: include string.h.
6166 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
6168 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
6170 (scm_addr_buffer_size): change type from scm_sizet to int.
6171 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
6172 from scm_sizet to int.
6174 * error.c: include unistd.h.
6176 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
6179 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
6181 * __scm.hd, def.sed: deleted.
6183 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
6185 Changes for NeXT, suggested by Robert Brown.
6186 * configure.in: Call AC_TYPE_MODE_T.
6187 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
6188 NeXT. Put header file list in alphabetical order.
6189 * configure, scmconfig.h.in: Regenerated.
6190 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
6192 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
6195 * acconfig.h: New file, providing documentation for the CPP
6196 symbols defined in configure.in
6197 * acconfig-1.5.h: Removed; superceded by the above.
6199 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
6201 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
6203 * fports.c (scm_open_file): don't return #f, throw error.
6205 * ioext.c (fileno): renamed from %fileno.
6206 (soft-fileno): deleted.
6208 * ports.c (scm_port_revealed): don't need to check for -1 from
6210 (scm_set_port_revealed_x): return unspecified, not #f.
6212 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
6214 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
6216 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
6218 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
6220 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
6222 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
6223 This is necessary on Ultrix, and doesn't hurt portability.
6225 * Makefile.in (dist-dir): New target, implementing a new dist system.
6226 (installed_h_files): Put in alphabetical order.
6227 Remove duplicate entries for markers.h and unif.h.
6228 (c_files): Remove duplicate entries for markers.c.
6229 (ancillary): Renamed from anillery; all uses changed. Remove
6230 PLUGIN; it's a directory, and needs special treatment in dist-dir.
6231 Remove all the ../doc/* files; doc/Makefile.in handles that.
6233 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
6235 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
6236 every if must have an else, or else the whole command has a
6237 non-zero exit code whenever the if's condition is false.
6239 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
6241 * posix.c: include string.h.
6243 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
6245 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
6248 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
6249 Remove leading % from scheme names.
6250 Do not return error values, call SCM_SYSERROR or similar.
6252 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.

6326 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
6327 handled correctly (SCM_FREEP was applied to them) -- test for

6496 initialization to fix a race condition.
6498 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

6525 The weird symbol syntax is also a bit bogus (emacs doesn't quite
