1 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
6 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
8 * objects.c (scm_i_make_class_object): Renamed from
9 make_class_object; exported; error checking moved to
10 scm_make_class_object and scm_make_subclass_object.
11 (scm_make_class_object, scm_make_subclass_object): Use
12 scm_i_make_class_object.
13 (scm_make_subclass_object): Let the subclass have same metaclass
16 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
18 * debug.c (scm_debug_options): Bugfix: Set the value of
19 scm_stack_checking_enabled_p after setting debug options;
20 #include "stackchk.h". (Thanks to Richard Polton.)
22 1998-11-13 Radey Shouman <rshouman@metro2000.com>
24 * unif.c (scm_array_contents): removed unnecessary test for 0
27 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
29 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
30 Replaced by macro `collect' in boot-9.scm.
32 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
34 * eval.c (scm_copy_tree): Copy source properties if existent.
36 * debug.c (scm_start_stack): Copy source when evaluating. (If we
37 don't, we may end up passing memoized source to a transformer.)
39 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
41 * stack.c (get_applybody): Help function which lookups the first
42 body form of the apply closure.
43 (read_frames): Prevent the source of the first form of the apply
44 closure from being recorded. This would only be confusing.
46 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
47 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
49 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
51 * stacks.c (read_frame): Bugfix: Removed lingering `else'
53 (read_frames): Use SCM_MACROEXPP.
55 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
57 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
58 don't contain interesting information since all arguments are
59 present in the frame which applies the compiled closure anyway.);
60 Skip the transformer application frames.
62 * print.c (scm_iprin1): Print gsubrs as primitives.
64 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
66 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
68 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
69 that we can identify these in a backtrace. (This change doesn't
70 introduce any significant speed penalty.)
72 * eval.c: Added note about `serial-map' using scm_map.
74 * read.c, read.h (scm_read_options, scm_read_opts): Removed
75 readline options. They should reside in their own options array.
77 * readline.c, readline.h (scm_readline_options,
78 scm_readline_opts): Moved readline options here.
80 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
82 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
83 SCM_ROCHARS instead of SCM_CHARS.
85 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
86 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
88 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
90 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
91 This is quite important since the latter clears the
92 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
93 every single character read...
95 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
97 * print.c (scm_iprin1): Removed suspect looking (and indeed
98 malevolent) semicolon after test for user supplied closure print
99 procedure. (Thanks to Telford Tendys.)
101 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
102 (scm_memq, scm_memv, scm_member): Do argument checking *before*
103 starting to search the list. Removed call to sloppy_mem_check.
105 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
106 procedures: Same as scm_delq_x et al, but delete maximally one
109 * options.c (scm_options, scm_init_options): GC-protect option
110 values of type SCM. (Thanks to Telford Tendys.)
112 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
114 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
115 make sure that there always is a "real" scm_lookupcar.
117 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
119 * read.c, read.h (history-length, history-file): New read options.
120 (scm_read_options): Stifle history to history length.
122 * readline.c (scm_read_history, scm_write_history): New
125 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
127 * eval.h (scm_macro_eval_x): Removed declaration.
129 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
130 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
131 Renamed and made global.
133 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
134 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
136 * evalext.c, evalext.h: New files. Contain non-R5RS things
137 having to do with evaluation.
139 * evalext.c (scm_serial_map): New procedure: Version of `map'
140 which guarantees that the procedure is applied to the lists in
142 (scm_m_sequence_to_list): New syntax: Version of `begin' which
143 returns a list of the results of the body forms instead of the
144 result of the last body form.
145 (scm_definedp, scm_m_undefine): Moved from eval.c
147 * evalext.h (scm_m_sequence_to_list): Added declaration.
149 * macros.c, macros.h: New files.
150 (scm_procedure_to_syntax, scm_procedure_to_macro,
151 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
152 scm_macro_name, scm_macro_transformer): Moved from eval.c
153 (scm_make_synt): Moved from eval.c
155 * procs.c, procs.h (scm_procedure_documentation): Moved from
158 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
161 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
163 * debug.c, print.c: Added #include "macros.h".
165 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
167 This change adds the ability to use `unread-char' multiple times
168 without interspersed reads and adds the new procedure
169 `unread-string'. The change is optimized for the common case of
170 unreading a single character. This is also the reason behind the
171 choice to store characters in the port itself: in most cases no
172 extra malloc is required.
174 The amount of code in some macros in ports.h has been increased to
175 the extent that they would fit better as C functions, but, since
176 this code belongs to the port representation, such functions
177 should be placed in ports.c which would cause calls back and forth
178 between ports.c and genio.c. That is not good for performance.
179 Also, keeping them as macros allows the compiler to do some
180 optimizations which are needed to make the current interface
181 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
183 One benchmark (Guile startup time) indicates an increase of
184 loading speed of 1%. Another (reading (using `read') boot-9.scm
185 10 times) shows no change in performance.
187 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
188 made to find a beautiful solution.)
190 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
191 (SCM_TRY_CLRDY): New macro: Only clear the first unread
192 character. (SCM_CLRDY clears all.)
193 (SCM_N_READY_CHARS): New macro: Returns number of unread
194 characters in a port. Returns wrong answer if SCM_CRDYP is false.
195 (struct scm_port_table): New fields: `entry' contains port table
196 index, `cp' points to last unread char, `cbuf' is the buffer for
197 unread chars, `cbufend' points after end of the character buffer.
199 * ports.h, ports.c (scm_unread_string): New procedure.
200 (scm_grow_port_cbuf): New function.
202 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
204 (scm_generic_fgets), fports.c (local_fgets): Use a loop
205 to read unread characters. Use SCM_TRY_CLRDY instead of
208 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
210 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
212 * genio.c, genio.h (scm_ungets): New function.
214 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
217 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
219 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
220 declarations. (Thanks to Russ McManus.)
222 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
224 * numbers.c (num2long): As a software archeologist, I'm proud of
225 this finding! :) Preliminary dating suggests an almost 4 year old
226 remnant from the SCM ancestor. The sample has been removed from
227 the finding site and is now safely stored in the repository.
229 * numbers.h: Removed prototype for num2long.
231 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
233 * gh_data.c (gh_scm2doubles): Make it possible to pass result
235 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
236 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
237 * gh.h: Updated and added prototypes.
239 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
241 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
243 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
245 * guile-snarf.in: Never generate an empty file. (Thanks to
248 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
249 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
250 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
251 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
252 gh_new_procedure5_0): Specify argument types, to appease C++
253 compilers. (Thanks to Brad Bowman.)
255 Bug reports from Russ McManus:
256 * guile-snarf.in: If the CPP environment variable is set, use that
257 as the C preprocessor, instead of the preprocessor autoconf
259 * snarf.h (SCM_PROC): Cast the function pointer passed to
260 scm_make_gsubr, to satisfy C++.
262 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
263 Use the handler passed, instead of ignoring it and using
264 gh_standard_handler. (Thanks to Etienne Bernard.)
266 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
268 * ports.h: Put text after #endif in comment. (Thanks to Nicolas

291 * script.c (scm_compile_shell_switches): Define
292 use-emacs-interface in the root module, so the repl code can see
293 it. See today's change to top-repl in ice-9/boot-9.scm.
295 * filesys.c (set_element, get_element): Make sure that `element'
296 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
297 Boekemeier and Jorgen "forcer" Schaefer.)
299 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
301 * chars.c (scm_charnames): In ASCII character name table, make
302 newlines print as #\newline by default, not #\nl.
304 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
305 alphabetical order. Oh thrills. But it helps me know how far
306 along in the compilation I am.
307 * Makefile.in: Regenerated.
309 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
311 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
312 #bytes(...) to #y(...), and syntax for short vectors from
313 #short(...) to #h(...). This may seem nutty, but, like the other
314 uniform vectors, byte vectors and short vectors want to have the
315 same print and read syntax (and, more basic, want to have read
316 syntax!). Changing the read syntax to use multiple characters
317 after the hash sign breaks with the conventions used in R5RS and
318 the conventions used for the other uniform vectors. It also
319 introduces complexity in the current reader, both on the C and
320 Scheme levels. (The Right solution is probably to change the
321 syntax and prototypes for uniform vectors entirely.)
323 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
325 Don't use local_fgets on sockets; ftell doesn't work on sockets.
326 (Thanks to Jorgen "forcer" Schaefer.)
327 * ports.h (SCM_NOFTELL): New flag.
328 * fports.c (local_fgets): If it's set, use the generic fgets.
329 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
331 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
333 * script.c (scm_compile_shell_switches): Add handling of -q switch
334 (inhibit loading of user init file).
335 (scm_shell_usage): Add usage text for -q switch.
336 (scm_compile_shell_switches): Always load user init file first if
339 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
341 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
342 and is now broken under NetBSD. I can't fathom what it's trying
343 to do, so I've replaced it with something that I do understand,
344 which seems to work, and which isn't broken on NetBSD. "Progress?
345 You Decide." (Thanks to Perry Metzger.)
347 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
348 signed/unsigned comparison.
350 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
352 Warning fixes from Greg Harvey:
353 * unif.c (scm_array_set_x): initializer for pos
354 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
355 * struct.c (scm_struct_ref, scm_struct_set_x): Added
356 initializers for field_type, since EGCS so desparately wants to
358 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
359 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
360 when GUILE_DEBUG is defined.
361 * dynwind.h (scm_wind_chain): Same.
362 * ports.h (scm_pt_size, scm_pt_member): Same.
363 * print.h (scm_current_pstate): Same.
364 * procs.h (scm_make_cclo): Same.
366 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
368 Handle short and long long uniform arrays properly. (Thanks to
370 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
371 raeql_1): Add cases for scm_tc7_svect (short vectors) and
372 scm_tc7_llvect (long long vectors).
374 Change the way libguile and boot-9.scm are timestamped, to try to
375 get rid of these spurious mismatch warnings. Now both
376 libguile/versiondat.h and ice-9/version.scm are generated directly
377 by the configuration process, rather than having version.scm
378 generated directly, and libguile/versiondat.h generated by the
379 Makefile, which is generated by configure. It seems that
380 sometimes the Makefile would change, but versiondat.h depends on
381 Makefile.in, not Makefile, so it wouldn't get rebuilt.
382 * Makefile.am (versiondat.h): Target removed; this is generated
383 directly by the configure script now.
384 (BUILT_SOURCES): Remove versiondat.h.
385 * versiondat.h.in: New file, transformed by the configure script
387 * Makefile.in: Regenerated.
389 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
390 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
391 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
392 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
393 if we want to use them in a header file some day, we can. (Thanks
396 * stime.c (scm_get_internal_real_time): Do the arithmetic using
397 SCM numbers, so we won't have rollover problems; the range of a
398 signed long in milliseconds is about 25 days. (Thanks to Karl
401 Don't redefine sleep and usleep; fix this problem now.
402 * coop.c (sleep, usleep): Remove declarations; we don't use or
403 redefine these any more.
404 (scm_thread_usleep, scm_thread_sleep): New functions which do the
405 job of usleep and sleep in a thread-friendly way. We can use
406 these in the rest of Guile. Define versions for systems both with
408 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
409 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
410 we're just using it, not redefining it, we can use a K&R style
412 (sleep): Declare this, too, if the system hasn't.
413 (scm_sleep, scm_usleep): Use scm_thread_sleep and
414 scm_uthread_sleep if they're available; otherwise, just call the
416 * scmconfig.h.in: Regenerated.
418 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
420 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
422 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
424 * threads.c: Doc fix.
426 The argument type of usleep varies from system to system,
427 as does the return type. We really shouldn't be redefining usleep
428 at all, but I don't have time to clean that up before the 1.3.
429 release. It's on the schedule for afterwards. (Thanks to Julian
431 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
433 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
434 * scmconfig.h: Regenerated.
436 * simpos.c (scm_software_type): Procedure deleted. This isn't the
437 right way to handle system variation. Autoconf's approach is the
439 * simpos.h (scm_software_type): Declaration deleted.
441 * script.c (scm_find_executable): Don't test if unix is #defined
442 here; first, NetBSD doesn't #define it, and second, it's the wrong
443 way to go about these things. (Thanks to Perry Metzger.)
444 (dld_find_executable): Delete this MSDOS support code. This isn't
445 the way we want to support this; it needs to be rethunk at a
448 * genio.c (scm_do_read_line): Don't just politely check that the
449 line was either non-empty or EOF. Abort if it's empty and not
452 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
454 * scmconfig.h.in: Regenerated.
456 * libguile.h: Don't omit the dynamic linking functions. (Thanks
459 * genio.c (scm_do_read_line): Count lines correctly when the file
460 doesn't end in a newline.
462 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
464 * genio.c (scm_do_read_line): Maintain the line count correctly.
465 (Thanks to Harvey J. Stein and Greg Harvey.)
467 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
470 * numbers.c (big2str): Protect t from garbage collection until
471 we're done. (Thanks to Gary Houston.)
473 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
475 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
477 * Makefile.in: Regenerated.
479 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
480 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
483 Do magic to mix reads and writes on stdio FILE-based ports.
484 (Thanks to Christian Lynbech.)
485 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
487 (pre_read, pre_write): New functions.
488 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
489 local_fputs): Call them.
490 (local_fflush): Mark the port as ready for reading and writing.
491 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
492 flags on new port objects. This might not be accurate --- who
493 knows what state the FILE * is in when we get it --- but it won't
494 do extraneous calls to fflush or fseek, so it's no worse than the
495 behavior before this change.
496 * ports.h: Add comment.
498 Centralize the creation of port objects based on stdio FILE * in
499 fports.c; don't just throw them together anywhere.
500 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
501 what the rest of Guile wants. Don't set the revealed count;
502 that's only appropriate for stdin, stdout, stderr.
503 (scm_standard_stream_to_port): This function does set the revealed
505 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
506 not scm_stdio_to_port.
507 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
508 * fports.c (scm_open_file): Same.
509 * posix.c (scm_pipe): Same.
510 * socket.c (scm_sock_fd_to_port): Same.
511 * ioext.c (scm_fdopen): Same.
512 (scm_freopen): Moved from here to...
513 * fports.c (scm_freopen): ... here. This is really something that
514 munges the internals of an fport, so it should go here.
515 * fports.h (scm_stdio_to_port): Adjust prototype.
516 (scm_standard_stream_to_port, scm_freopen): New protoypes.
517 * ioext.h (scm_freopen): Prototype removed.
519 * filesys.c (set_element, get_element): This can work on both pipe
520 and file ports, so use SCM_FPORTP to typecheck, instead of testing
523 * scmconfig.h.in: Regenerated.
525 Change the definition of the functions in scm_ptobfuns so that
526 they get passed the port object, not the port's stream.
527 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
528 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
529 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
530 Pass the port itself to the scm_ptobs function.
531 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
532 scm_generic_fgets): Same.
533 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
534 getc_void_port, fgets_void_port, close_void_port): Just change the
535 argument names; these functions don't really do anything.
536 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
537 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
538 port as an argument, and use SCM_STREAM to get the stdio FILE *.
539 Also, use prototyped definitions, and get rid of the extra
541 (scm_fptob, scm_pipob): We don't need casts here any more.
542 * strports.c (prinstpt): Use prototype declarations.
543 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
544 and use SCM_STREAM to get the string info. Also, use prototyped
545 definitions, and get rid of the extra declarations.
546 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
549 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
550 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
552 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
553 scm_fgets, for consistency.
554 (scm_fptop, scm_pipob): References updated.
556 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
558 Include the source location in error messages for scripts.
559 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
560 stack is still there when we catch the error.
561 * throw.c (handler_message): If we are handling an error with a
562 message, then put together the proper arguments and call
563 scm_display_error, instead of scm_display_error_message. That
564 displays source location, if it can find it.
566 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
568 * gc.c (scm_unprotect_object): Change this so that calls to
569 scm_protect_object and scm_unprotect_object nest properly.
570 (scm_protect_object): Doc fixes.
572 * strings.c (scm_string_set_x): Require the argument to be a
573 writable string, not a substring or a symbol.
574 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
575 (Thanks to John Redford and Charbel Jacquin.)
577 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
579 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
581 * eval.c (safe_setjmp): Remove this misunderstanding.
582 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
585 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
587 * libguile.h: Mark these as C declarations, for compilation by C++
590 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
591 __cplusplus clause. I seriously doubt this ever worked the way
592 the author seems to have intended.
594 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
596 Utterly needless cleanups to hopelessly messy code.
597 * ports.c: Doc fixes.
598 (scm_fflush): Moved to ...
599 * genio.c (scm_fflush): ... here, amongst all the other port
600 method invocation functions.
601 * genio.h, ports.h: The prototype moves too.
603 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
605 * backtrace.c (display_error_body): The current frame does not
606 always have a parent frame; consider a function called directly
607 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
610 * alloca.c (alloca): Undo yesterday's changes, and simply call
611 malloc directly for storage, and abort if we don't get what we
612 want. The situation is much simpler --- just call malloc. Emacs
613 has bizarre/evil requirements (signal handlers might malloc unless
614 you set this global flag, so you have to set the flag around all
615 calls to malloc) which we are certainly not going to conform to,
616 so we can do the simple and obvious thing.
618 * coop.c (coop_condition_variable_wait): Make this function
619 static. It's only useful internally --- you should never just
620 wait on a condition variable.
621 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
623 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
625 * unif.c (scm_array_set_x): Accept any kind of number as an
626 element for a uniform vector of doubles. This is more consistent
627 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
629 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
630 works; I can't conveniently test it myself. (Thanks to Dvid
631 Tillman for the bug report.)
635 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
636 from here, not from scm_compile_shell_switches (which is a pretty
637 dumb place to do it).
638 (scm_load_startup_files): New function.
639 (scm_ice_9_already_loaded): Variable moved to here from script.c.
640 * script.c (scm_compile_shell_switches): Don't load the startup
642 (scm_ice_9_already_loaded): Variable moved.
643 * init.c (scm_load_startup_files): Prototype for new function.
644 * gh_init.c (gh_enter): Doc fix.
646 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
648 Some anti-warning changes from Greg Harvey.
649 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
650 warnings when it doesn't understand our NORETURN declarations in
652 * posix.c (scm_mknod): Similar.
654 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
656 * posix.c (scm_getpwuid): If we can't find an entry, return our
657 own message, instead of using scm_syserror --- the getpwMUMBLE
658 functions don't set `errno' to anything interesting.
660 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
662 Get rid of warnings from the cooperative threading system.
663 * threads.h (scm_single_thread_p, scm_yield,
664 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
665 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
666 scm_wait_condition_variable, scm_signal_condition_variable): Add
667 prototypes for these Scheme-visible functions.
668 * coop-defs.h (coop_next_runnable_thread,
669 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
670 Prototypes for these here, even though they're from iselect.c.
671 (coop_condition_variable_wait, coop_join): Add prototypes.
672 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
673 scm_threads_free_condvar): Make these smob functions static.
674 * coop-threads.h (coop_init): Give this a real prototype.
675 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
676 (coop_next_runnable_thread): No need to provide prototype; it's in
679 * scmconfig.h.in: .detarenegeR
681 * iselect.c, threads.c: Doc fixes.
683 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
685 * Makefile.in: Regenerated with a patched automake, to get
686 dependency generation right when using EGCS.
688 * inet_aton.c (inet_aton): Add prototype, to remove compiler
689 warning. (Thanks to Robert Pluim.)
691 * inet_aton.c (inet_aton): Reassure the compiler that the
692 arguments to the <ctype.h> macros are all unsigned characters, not
695 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
697 Getting rid of more warnings...
698 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
699 today's change to ../configure.in.
700 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
701 * scmconfig.h.in: Regenertaded.de.,.__
702 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
703 (scm_localtime, scm_mktime): Use a const char * to manipulate the
706 * readline.c: Doc fix.
707 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
708 * readline.h (scm_filename_completion_function): Add prototype.
709 (scm_init_readline): Make this into a prototype.
711 * readline.c (scm_filename_completion_function): Use SCM_PROC to
712 declare this, instead of calling scm_make_subr manually.
714 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
716 * readline.h (scm_init_readline): Add prototype for this.
717 (scm_init_readline): Make this a real prototype.
719 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
721 Warning fixes from Maciej Stachowiak:
722 * backtrace.h (scm_display_application, scm_backtrace): Add
724 * debug.c (scm_m_start_stack): Make this function static.
725 * fluids.h (scm_fluid_p): Add prototype.
726 * procprop.c (scm_i_procedure_arity): Make this function static.
727 * regex-posix.c (scm_regexp_error_msg): Make this function static.
728 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
729 * root.h (scm_dynamic_root): Add external prototype.
730 * scmsigs.h (scm_usleep): Add external prototype.
731 * script.h (scm_init_script): Use prototype, not K&R decl.
732 * stacks.h (scm_stack_id): Add external prototype.
733 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
735 1998-09-30 Mark Galassi <rosalia@cygnus.com>
737 * gh.h: took out the definitions of vset and vref, since they are
738 replaced by the proper vector routines that correspond to the R4RS
741 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
743 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
744 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
745 third argument, a C expression that should result in a SCM value,
746 which is used to initialize the variable. Reimplemented
747 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
750 * version.h (scm_libguile_config_stamp): Add prototype.
751 (From Maciej Stachowiak.)
753 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
755 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
756 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
758 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
760 * print.c (scm_iprin1): Rather than having one i, and using it in
761 several places, declare a fresh i local to each block where it is
762 used, and give it a signedness appropriate to its use in each case.
765 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
768 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
769 signed/unsigned clashes.
771 * posix.h (scm_tmpnam): Added prototype.
773 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
774 scm_make_subclass_object): Add external prototypes.
776 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
777 comparison is okay here.
779 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
781 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
782 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
784 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
787 * load.c (swap_port): Make this function static.
789 * load.c (scm_search_path): Make max_path_len and max_ext_len
790 unsigned, since they're compared against string sizes.
792 * load.c (init_build_info): Make i unsigned.
794 * ioext.h (scm_read_line): Add prototype.
796 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
797 scm_hash_fn_remove_x): Make hash bucket index local variable k
798 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
799 accurately as possible.
801 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
802 comparisons, and range checking to make sure those casts are
805 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
806 signed/unsigned comparisons.
808 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
809 avoid signed/unsigned comparisons.
810 * smob.h (scm_numsmob): Change extern declaration to match.
812 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
813 avoid signed/unsigned comparisons.
814 * ports.h (scm_numptob): Change extern declaration to match.
815 (scm_current_load_port, scm_set_port_line_x,
816 scm_set_port_column_x): New prototypes.
818 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
819 test code, and it causes warnings.
821 * gh.h (gh_int2scmb, gh_uniform_vector_length,
822 gh_uniform_vector_ref): Added prototypes.
824 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
825 debugging support unconditionally. That's backtrace.c, stack.c,
826 debug.c, and srcprop.c.
827 (EXTRA_libguile_la_SOURCES): Omit those from here.
828 * Makefile.in: Regenerated.
830 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
832 * options.c (scm_options): Bugfix: Allow empty list of options!
834 * debug.c, debug.h (scm_single_step): Removed.
835 (scm_with_traps): New procedure. This procedure could easily be
836 written in Scheme but needs to be highly optimized.
838 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
840 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
841 Check SCM_TRAPS_P before trapping.
843 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
845 Changes to avoid signed/unsigned comparison warnings.
846 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
847 (scm_gc_sweep): Make n and j local to the blocks they're used in,
848 so they can have appropriate types for each application. Make i
849 signed. Use initializers in some spots. I'll probably pay for
851 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
852 (scm_must_realloc): Make nm unsigned.
853 (init_heap_seg): Make new_seg_index and n_new_objects signed.
854 (scm_init_storage): Use prototype-style definition, and make the
856 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
857 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
859 * filesys.c (scm_readlink): Make local vars rv and size ints, to
860 avoid signed/unsigned comparison warnings, and because the return
861 value of readlink may be -1. Don't bother casting the third
862 argument to readlink.
864 * filesys.c (scm_dirname, scm_basename): Move these to their own
865 page, at the end of the file.
866 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
868 * eval.h (scm_eval_options_interface): Add external prototype for this.
869 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
871 * eval.c (scm_lookupcar1): Make this static.
873 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
874 Make these prototype declarations, not K&R-style.
876 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
877 unsigned comparison warning.
879 * appinit.c: File removed. It had a single function in it, empty,
880 whose reason for existence is explained in no documentation or
881 comment. I think it's there as a default for some Tcl-style
882 initialization, but Tcl abandoned that approach a while ago.
883 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
884 (BUILT_SOURCES): Remove appinit.x.
885 * Makefile.in: Regenerated.
887 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
889 * Makefile.in: Regenerated using the last public version of
890 automake, not the hacked Cygnus version.
892 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
894 Remove Totoro kludge.
895 * Makefile.in, scmconfig.h.in: Regenerated.
896 * init.c, readline.c: Don't check if TOTORO is #defined.
898 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
900 * Makefile.am: Adjust for new thread configuration system.
901 (INCLUDES): Include the value of THREAD_CPPFLAGS.
902 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
904 (THREAD_LIBS): Definition deleted; automake will generate such
905 things automatically.
906 * Makefile.in: Regenerated.
908 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
910 Simplify smob and port marking; set the mark bit in the generic
911 marking code, and make marker routines only responsible for
912 turning up outgoing pointers.
913 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
914 before calling the marking function. Don't call the marking
915 function if it's zero.
916 * markers.c (scm_mark0): Just return #f. This function isn't
917 necessary at all now, but it's harmless to call it. We'll leave
918 it in so other folks' code doesn't croak at link time.
919 (scm_markcdr): Don't call SCM_SETGC8MARK.
920 * async.c (mark_async): Don't call SCM_SETGC8MARK.
921 * dynl.c (mark_dynl_obj): Same.
922 * root.c (mark_root): Same.
923 * srcprop.c (marksrcprops): Same.
924 * unif.c (markra): Same.
925 * variable.c (scm_markvar): Same.
926 * ports.c (scm_markstream): Same.
927 (void_port_ptob): Specify zero for our marking function.
928 * debug.c (debugobjsmob): Same.
929 * dynwind.c (guardsmob): Same.
930 * filesys.c (dir_smob): Same.
931 * fluids.c (fluid_smob): Same.
932 * fports.c (scm_fptob, scm_pipob): Same.
933 * mallocs.c (mallocsmob): Same.
934 * regex-posix.c (regex_t_smob): Same.
935 * smob.c (freecell, flob, bigob): Same.
936 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
937 * throw.c (jbsmob, lazy_catch_funs): Same.
939 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
941 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
942 scm_copy_tree on code in order not to let memoized code to leak
943 out. Thus, scm_copy_tree needs to copy vectors as well since
944 quasiquote can introduce evaluated code also inside vector
947 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
949 * eval.c (scm_copy_tree): Removed ability to copy vectors.
951 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
952 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
955 * unif.c: Say that ivect and uvect are of type signed and unsigned
956 long instead of int in commentary so that it correctly describes
959 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
961 * stime.c: Removed declaration of strptime. (It should be
962 declared by the system headers. If it turns out that some systems
963 don't, we'll handle that then.) (Thanks to Greg Troxel.)
965 * stime.h: Renamed TIMEH --> STIMEH
967 * backtrace.c (scm_display_error, scm_display_backtrace): In order
968 to increase portability, don't use structure assignment.
969 (Thanks to Nicolas Neuss.)
971 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
973 (finalize_fd_sets): Added empty statement after last case label.
974 (Thanks to Nicolas Neuss.)
976 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
979 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
981 * init.c, readline.c: OK, I won't have these readline.x bug
982 reports anymore. We've had them since April. The current reason
983 is a completely unintelligible failure of totoro.red-bean.com to
984 do the test for rl_getc_function in libreadline correctly. This
985 kludge overrides the test if we're on totoro so that the snapshot
986 generation process can work.
988 * readline.c: Define a strdup replacement if not existent on system.
990 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
992 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
993 This change makes scm_make_vector R5RS compatible. We cannot keep
994 the third argument since people want to be able to deduce the form
995 of the C function call only by looking at R5RS. (At the same time
996 we have removed some unnecessary complexity!)
998 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
999 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
1000 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
1001 argument in call to scm_make_vector.
1003 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1005 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
1006 This macro is useful in applications.
1008 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1018 * filesys.c (dirname, basename): New procedures.
1020 * init.c (scm_boot_guile_1): Removed condition around
1023 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a

1042 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1044 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
1045 not a tty, return #f.
1047 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
1048 to Julian Satchell and Roland Kaufmann.)
1050 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.

1055 * debug.h, debug.c (scm_start_stack): New function. Implements
1056 the guts of old scm_m_start_stack.
1058 * debug.c (scm_m_start_stack): Use scm_start_stack.
1060 * init.c (scm_start_stack, scm_restart_stack): Renamed to
1061 start_stack and restart_stack. (These have static scope.)
1063 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1065 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
1066 readline functions to come in release 2.3. (Thanks to Chet
1068 (handle_errors): Use the above functions.
1070 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1072 * readline.c: Improvements for readline support: Handle errors
1073 better; Implement before-read-hook.
1075 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1077 * init.c (scm_boot_guile_1), readline.c: Test for
1078 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
1079 assure that we have version >= 2.1.)
1081 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
1083 * readline.c (scm_readline): Defer interrupts while we're calling
1086 * readline.c (scm_add_history): Bugfix: Do strdup before giving
1087 away the string to add_history.
1088 (completion_function): Do completion for readline. (Thanks to
1090 (scm_filename_completion_function): New procedure: Filename
1092 (current_input_getc): New function. Use this one instead of
1093 standard getc from readline.
1095 * throw.c, throw.h (scm_handle_by_throw): New function: This
1096 handler throws errors to next handler on the dynwind chain.
1098 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
1100 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
1103 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1105 * procprop.c (scm_i_procedure_arity): New function. Returns arity
1107 (scm_procedure_properties): Modified to return arity together with
1109 (scm_procedure_property): Added the read-only property `arity'.
1110 (scm_set_procedure_property_x): It is an error to set the `arity'
1113 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
1114 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
1116 * procprop.h (scm_sym_arity): New symbol.
1118 * objects.c (scm_set_object_procedure_x): New procedure: Use this
1119 to set the dispatch procedure of an operator or entity object.
1121 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
1122 Made procedure slots read-only.
1124 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
1125 scm_tcs_cons_gloc case in zero args switch; Fixed args
1126 construction for operators in scm_tcs_cons_gloc case in two args
1129 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1131 * fluids.c: Removed use of assert.h (in order to avoid
1134 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
1136 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
1138 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
1139 change makes the evaluator safer at the cost of evaluation speed.
1140 It handles the case when the user has added a non-immediate
1141 improper end of the application form, e.g., `(+ 0 . x)'.
1142 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
1143 minimize the extra cost as much as possible. The new code is
1144 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
1145 problem with structs planted directly in the code (e.g. by a
1146 macro). This no longer causes segmentation fault. (Thanks to
1149 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
1150 arg `proc' in order to be able to throw errors; New argument
1153 * Removed extra #include "debug.h"
1155 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
1157 * scmsigs.c: Declare usleep as returning void on some systems.
1158 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
1161 * coop.c (usleep): Return void on some systems.
1163 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1165 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
1167 * coop.c: Changed return type of usleep to int.
1169 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
1170 isn't found in the OS.
1172 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
1173 isn't enabled. (Thought that I had made this change ages ago...)
1175 * iselect.c: Declare bzero if not defined by OS.
1177 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1179 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
1180 condition. (Thanks to John Tobey.)
1182 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
1183 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
1186 * __scm.h: Start the long-term project of moving to POSIX threads.
1187 Phase 1: Classification of all critical sections.
1188 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
1189 for A sections. (See comments in __scm.h for details.)
1191 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
1192 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
1194 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1196 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
1197 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
1198 (libpath.h, versiondat.h): Replaced dependency on Makefile with
1199 dependencies on $(srcdir)/Makefile.in
1200 $(top_builddir)/config.status in order to avoid circularity.
1202 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
1203 from argc if argc was 0 initially.
1205 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
1206 in generation of libpath.h.
1208 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
1210 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
1211 libguile from 2 to 3.
1213 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
1215 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
1217 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
1219 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
1220 scm_set_port_column_x, scm_port_filename,
1221 scm_set_port_filename_x): Removed optional arguments. Added
1222 proper argument checking.
1224 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
1225 stack size in machine words.
1227 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
1228 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
1229 to Ole Myren Röhne.)
1231 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
1233 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
1234 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
1236 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
1239 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
1240 procedure apply: Copy argument lists before pushing them unto the
1241 environment so that the environment won't get mutated due to
1242 manipulation of procedure arguments. This should perhaps be
1243 regarded as a temporary solution until someone finds a more
1244 efficient one. (Thanks to Maciej Stachowiak.)
1246 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
1248 * script.c (scm_compile_shell_switches): Use "guile" as default
1249 zero arg if argc is NULL.
1251 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
1253 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
1254 is zero. (Thanks to Dirk Herrmann.)
1256 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
1258 * ports.c (scm_add_to_port_table): First line is now line 0
1259 (was 1). (Interface changed according to suggestion by Per
1262 * backtrace.c (display_header): Add 1 to line and column numbers
1263 when presenting them to the user.
1265 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
1266 from debug.c --> eval.c
1268 * eval.h, eval.c (scm_eval_options_interface): New options
1270 (SCM_EVAL_STACK): New option: Size of newly created stacks,
1271 i.e. stacks for new threads.
1273 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
1275 * eval.c (unsafe_setjmp): Removed with #if 0.
1277 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
1280 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
1281 to avoid compiler warnings.
1283 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
1285 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
1287 * throw.c (handler_message): Print message on current error port
1288 instead of default error port. (Thanks to Maciej Stachowiak.)
1290 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
1292 * ports.c (scm_add_to_port_table): allocate in units of
1293 struct scm_port_table *, not struct scm_port_table.
1294 * posix.c (scm_close_pipe): remove the port from the port table
1296 Thanks to Rob Engle for both fixes.
1298 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1300 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
1301 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
1303 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1305 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
1307 * backtrace.c (display_error_body, display_backtrace_body),
1308 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
1309 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
1310 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
1311 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
1314 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
1315 don't receive the jmpbuf arg anylonger.
1316 (scm_catch): Don't accept a #f tag.
1317 (scm_throw): Check that key is a symbol.
1318 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
1320 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
1322 * async.c (async_pending): Removed declaration.
1324 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1326 * dynwind.c (scm_wind_chain): New debug function.
1328 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
1329 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
1330 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
1331 extra layer of functions around the body and handler of a thread.
1332 This extra layer makes sure that the handler is called in the
1333 dynamic context of the surround (= empty dynwind list), but under
1334 the *dynamic root* of the body. We can not use the dynamic root
1335 of the surround since that root belongs to another thread => stack
1336 is not handled correctly. It may seem ugly to use this extra
1337 layer, but the extra cost in terms of execution time is really
1338 negligible compared to the total amount of time required to create
1339 a thread, and it would reduce maintainability to duplicate the
1340 crucial and complicated steps performed by cwdr.
1342 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
1343 (SCM_ALLOW_INTS): Added thread switching code before interrupts
1344 get re-enabled. The important effect of this is that interrupts
1345 are blocked during thread switching so that thread data structures
1346 don't risk getting messed up by an unfortunate signal.
1347 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
1348 seems to do more aggressive optimization which actually move
1349 instructions around in these macros in a fatal way. Therefore:
1350 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
1351 just superstitious...)
1352 (SCM_TICK): Maybe do a context switch and take care of asyncs.
1353 This macro should be used instead of SCM_ASYNC_TICK since the
1354 latter doesn't do context switches any more.
1356 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
1357 instead of SCM_ASYNC_TICK.
1359 * coop.c, iselect.c: Since thread switches are now performed with
1360 interrupts masked, we can't use the old mechanism of delivering
1361 signals immediately when they arrive. Signals must instead be
1362 delivered when the asyncs run *after* the end of the critical
1363 section in scm_internal_select. But this also means after context
1364 switch so that the signal will be delivered to a different thread.
1365 To avoid this, I have changed the protocol of
1366 coop_wait_for_runnable_thread and friends so that they are allowed
1367 to return the original thread. So, if a signal arrives during
1368 scm_internal_select, we won't any longer be forced do a context
1369 switch, but can remain in the same thread and deliver the signal
1372 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
1373 scm_asyncs_pending and made it global.
1375 * iselect.c: Small fixes.
1377 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
1378 coop_condition_variable_init, coop_condition_variable_wait,
1379 coop_condition_variable_signal): Changed return type from `void'
1380 to `int'. This is to adhere closer to the pthreads interface.
1381 This, in turn, is part of an attempt to provide C versions of the
1382 mutex and condition variable primitives which can be part of a
1383 frontend to COOP or pthreads.
1385 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
1386 coop_condition_variable_destroy): New functions.
1388 * coop-threads.c (scm_wait_condition_variable): Use
1389 coop_condition_variable_wait_mutex.
1391 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
1392 Definitions moved to coop-defs.h.
1394 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
1395 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
1396 scm_cond_destroy): New C interface to mutecis and cond vars.
1398 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1400 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
1402 * iselect.c: Now several threads can wait on the same file
1403 descriptor. The behaviour is compatible with OS select: All
1404 threads waiting for the fd return with the same status.
1406 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1408 * coop-threads.c, threads.h (scm_spawn_thread): New function.
1409 Can spawn a thread from application C code.
1411 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1413 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
1414 gh_doubles2scm): New functions.
1416 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
1418 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
1419 commented-out version of gh_eval_str()
1421 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
1423 * socket.c (scm_bind): free soka after use.
1425 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
1427 * stime.c (tzvar): new variable.
1428 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
1429 avoid memory leaks when allocating.
1431 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
1433 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
1436 * gc.c, tags.h: Doc fixes.
1438 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1440 * eval.c (macro-eval!): Removed. This function was a design bug.
1441 It allowed memoized code to leak out to the scheme level. Most
1442 things that you could do with `macro-eval!' can be done with
1445 1997-12-20 Tim Pierce <twp@skepsis.com>
1447 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
1448 scm_fgets now depends on ftell(3) to know how many bytes were
1451 1997-12-15 Tim Pierce <twp@skepsis.com>
1453 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
1454 dealing with strings.
1456 1997-12-13 Tim Pierce <twp@skepsis.com>
1458 Make %read-line more suitable for implementing read-line efficiently.
1459 * ioext.c (scm_read_line): Strip the terminating newline from a
1460 string, and return a cons of the string and its terminator.
1462 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
1463 of the string that is read is stored in this memory location.
1464 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
1465 * genio.c, genio.h (scm_do_read_line): Update caller.
1466 * ports.h (scm_ptobfuns): Update typedef.
1467 * fports.c (scm_fptob, scm_pipob): Update struct.
1469 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1471 * filesys.c (set_element): Return file descriptor.
1472 (fill_select_type): Return the highest file descriptor.
1473 (scm_select): Tell select about the highest file descriptor. On
1474 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
1475 Therefore the extra overhead for calculating the maximum fd seems
1476 to be more than compensated. Is this correct? In any case,
1477 scm_internal_select will be much faster with this info.
1478 (scm_select, fill_select_type, set_element): Don't accept any kind
1479 of object in the file descriptor list or vector.
1481 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1483 * iselect.c (finalize_fd_sets): Bugfix.
1485 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1487 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1488 when using scm_internal_select (since we might switch to another
1491 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1493 * simpos.c (scm_system): always define: use sysmissing if not
1494 available. Check for HAVE_SYSTEM instead of _Windows (does
1495 Windows lack system or does it have an unusable one?).
1496 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1497 Let the argument be optional: if not supplied, call system(NULL).
1499 * ports.c (scm_close_port): relax the type check from OPPORTP to
1500 PORTP; closing a closed port is allowed.
1502 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1504 * fports.c (scm_fgets): Return if the last char in a chunk is
1505 newline. When fgets returns a string whose length is `size-1', it
1506 is ambiguous whether a whole line was retrieved, so we must check
1507 explicitly whether a line terminator is present.
1509 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1511 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
1512 before taking the CDR. (Thanks to Harald Meland.)
1514 * filesys.c (scm_stat): Slightly optimized.
1516 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
1518 * ports.c (scm_close_port): Make sure the port is open before
1521 * guile-snarf.in: Pass args through to gcc in a way that preserves
1522 whitespace boundaries. (Thanks to Greg Badros.)
1524 1997-12-02 Tim Pierce <twp@skepsis.com>

1560 --> the_last_stack_fluid.
1562 * backtrace.c: Added #include "fluids.h"

1591 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1592 replacement in iselect.c.
1593 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1594 coop_join): If GUILE_ISELECT enabled, use
1595 coop_wait_for_runnable_thread instead of
1596 coop_next_runnable_thread.
1597 (usleep, sleep): New replacements for system functions if
1598 GUILE_ISELECT is enabled.
1600 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1602 * coop-defs.h (coop_t): Added fields used by scm_internal_select.

1617 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1618 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1619 and scm_must_free, since ultimately the string returned will be copied
1620 by scm_makfrom0str anyway. Also, read any characters that may have
1621 been pushed onto the port with scm_ungetc.
1622 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1623 * ioext.c (scm_read_line): Free string after Guilifying it.

1637 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1639 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1640 and to invoke scm_shell().
1641 (gh_launch_pad): took out the loading of boot-9.scm from here,
1642 since it is probably best to let the user control that. In fact,
1643 gh_repl() now invokes scm_shell() which does that.
1645 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1647 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()

1672 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1674 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when

1682 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1684 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1685 OPORT is an `open' port, not an output port.

1694 scm_close_all_ports_except, scm_set_current_output_port,
1695 scm_set_current_error_port): Likewise
1696 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1697 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):

1711 exactly what we want to leave in to detect substrings.
1712 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1713 * tags.h: Fix diagrams and comments describing the S tag bit;
1714 remove vestigial remarks about the D tag bit.

1716 * strings.c: Formatting tweaks.
1718 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1719 variable first; then SCHEME_LOAD_PATH, with a warning message.

1737 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1739 * gh_data.c (gh_vector_set_x): changed name to make it consistent

1763 complete the picture R4RS functions that should be mirrored in the
1766 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1768 * tags.h (scm_tc7_substring): Changed the comment and code to
1769 conform with the changes below. Folks! We have suddenly two new
1770 free tc7 codes!!! Jummy, jummy!

1834 * gh_test_c.c (c_vector_test): some improvements on the vector
1837 * gh.h (gh_vector): this used to exist but do the wrong thing.
1838 Now it (almost) does the right thing, though it takes a list
1839 instead of the individual arguments. I need to see how it could
1841 (gh_list_to_vector): added this function as a macro. Corresponds
1842 to Scheme's (list->vector ...).

1850 (gh_make_vector): this used to be (stupidly) called gh_vector().
1851 This is the right name, since it does the same thing as the Scheme

1901 transformers. (They are always: exp env.); Bugfix: Unmemoize
1902 transformer source with correct environment.

1912 (scm_internal_cwdr): New function to perform the function of cwdr
1913 but take args that are more useful to C code. Also, the handler
1914 is now invoked *outside* of the new dynamic root, like the docs
1915 say. We no longer have to catch absolutely all errors, the caller
1916 is responsible for using a handler that does not throw, if he
1918 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1919 * root.h (scm_internal_cwdr): New prototype.
1921 Even more but risky streamlining:
1923 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1924 allocation of the jumpbuf of a root continuation. The changes
1925 below are controlled by it. They are now deactivated.
1926 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1927 the JMPBUF of the scm_rootcont to NULL before returning.
1929 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1930 when they are non-NULL.

1953 Accept a port/print-state pair in addition to just a port.
1954 (scm_prin1): Don't return the print_state to the pool when it has
1956 (scm_printer_apply): Set `revealed' field of print_state to true.
1957 (scm_init_print): Set scm_print_state_vtable.

1967 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1969 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1970 was looping endlessly.
1972 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1974 * strports.c (scm_eval_string): Don't close the port.
1976 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1977 former returns a nice normal integer. (Thanks to Daniel
1980 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1982 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1983 makefile variable as a build parameter called LIBS. The
1984 build-guile program will use this, for the time being.
1985 * Makefile.in: Regenerated.
1987 Thanks to Shiro Kawai:
1988 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1989 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1992 * Makefile.in: Regenerated with automake 1.2a.
1994 * script.c (scm_compile_shell_switches): If we hit the -c or --
1995 arguments, don't set the car of (command-line) to scm_usage_name,
1996 the prettified name of the guile executable; give it the full
1997 path, the way shells usually handle $0.
1999 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2001 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
2002 Scheme-level name `array-map' and renamed `serial-array-map' to
2003 `serial-array-map!'.
2005 * backtrace.c: Introduced exception handlers which now enclose
2006 `display-error' and `display-backtrace' so that error reporting
2007 won't get into infinite loops if an error occurs during displaying
2008 of the error. This can very easily happen with user supplied
2009 print call-back routines.
2011 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2013 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
2014 the names `serial-array-map' and `array-map' should be removed.)
2016 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
2018 * init.c (scm_boot_guile_1): Added scm_init_objects ().
2019 Added #include "objects.h"
2021 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
2022 Add #include "feature.h".
2024 * Makefile.am (libguile_la_SOURCES): Added objects.c.
2025 (modinclude_HEADERS): Added objects.h.
2027 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
2028 This test is needed at many places in the code and should be
2029 abstracted. (Motivated by the need of this test in libguiletk.)
2031 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
2032 (scm_eval_string), load.c (scm_primitive_load,
2033 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
2034 Use SCM_EOF_OBJECT_P.
2036 * eval.c (scm_init_eval): Add feature `delay'.
2038 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2040 * scmhob.h: Removed.
2042 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2044 * list.h (SCM_LISTn): New macros. Make list creation in C code
2045 prettier. The idea comes from STk.
2047 * sequences.h, sequences.c, append.h, append.c: Removed. These
2048 files implemented non-R4RS operations which would encourage
2049 non-portable programming style and less easy-to-read code.
2051 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
2054 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
2055 sequences.h, #include append.h.
2057 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
2060 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
2062 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
2064 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
2066 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2068 * eval.c: Added #include "objects.h"
2070 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
2073 * smob.c (scm_smob_prehistory): Create two objectsmobs with
2074 adjacent smob numbers.
2076 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2078 * procprop.h: Added declaration of scm_i_inner_name.
2080 * gsubr.c: New global symbol scm_i_inner_name.
2082 * debug.c (scm_procedure_name): Try procedure property
2083 `inner-name' if `name' fails.
2085 * print.c (scm_iprin1): Use scm_macro_name.
2087 * eval.c (scm_m_define): Give names to macros as well; Only the
2088 first top-level definition gives a procedure/macro a name.
2089 Otherwise confusing names can turn up in backtraces.
2090 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
2091 `name'; Give names to macros as well.
2093 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
2094 (scm_macro_transformer): Use SCM_CLOSUREP instead of
2097 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2099 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
2101 (prinmacro): Removed. The code has been moved/merged into print.c
2102 in order to decrease code redundancy. We want macros to print in
2103 a way equivalent to procedures, and it would be silly to duplicate
2104 the required code. (We don't want to maintain two places.)
2105 (macrosmob): Print field is now a NULL pointer.
2107 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
2108 scm_macro_transformer): New prototypes.
2109 (scm_tc16_macro): Declared.
2111 * print.c (scm_iprin1): Added code for printing of macros. Macros
2112 are now printed in a way equivalent to procedures.
2114 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
2116 * procs.h (scm_closure_p): Added declaration.
2118 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2120 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
2121 Shouldn't pass "heap" as the subr name.
2123 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
2125 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
2126 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
2127 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
2128 gh_equal_p): Use SCM_NFALSEP, instead of testing against
2129 SCM_BOOL_T. Any non-false value is true.
2131 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2133 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
2134 scm_gensym): Added prototypes.
2136 * symbols.c (scm_gensym): New function. This will speed up
2137 certain types of applications (such as macro systems) which
2138 generate lots of symbols.
2140 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2142 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
2144 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
2146 * unif.c (scm_shap2ra): tighten the checking of the array dimension
2147 specifier, since (2) or (2 . 3) would cause SEGV.
2148 (scm_transpose_array): more argument checking fixes.
2150 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
2152 * Makefile.in: Regenerated.
2154 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
2156 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
2158 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2160 * error.c, error.h (scm_error_callback): Removed (see NEWS).
2162 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
2164 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
2165 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
2168 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
2169 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
2170 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
2171 scm_array_p, scm_array_rank, scm_array_dimensions,
2172 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
2173 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
2174 scm_array_prototype): Added case scm_tc7_wvect.
2176 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
2178 * errno.h: prototype for scm_strerror.
2179 * error.c (scm_strerror): new procedure.
2181 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2183 * list.c (scm_list_append_x): Allow non-pair as last argument.
2184 This is consistent with the R4RS append and is probably the
2185 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
2187 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2189 * stime.h: prototype for scm_times.
2190 * stime.c (scm_times): new procedure.
2191 * ioext.c (scm_fseek): if the first argument is a file descriptor
2193 (scm_ftell): if the first argument is a file descriptor call lseek
2195 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
2196 * filesys.c (scm_chmod): if the first argument is a file descriptor,
2198 (scm_chown): if the first argument is a port or file descriptor,
2200 (scm_truncate_file): new procedure.
2201 Add DEFER/ALLOW INTS to a few other procedures.
2202 (scm_fsync): new procedure.
2203 (scm_open_fdes): new procedure.
2204 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
2206 (scm_fcntl): the first argument can now be a file descriptor. The
2207 third argument is now optional.
2209 * posix.c (scm_execl, scm_execlp): make the filename argument
2210 compulsory, since omitting it causes SEGV.
2211 (scm_sync): return unspecified instead of #f.
2212 (scm_execle): new procedure.
2213 (environ_list_to_c): new procedure.
2214 (scm_environ): use environ_list_to_c. disable interrupts.
2215 (scm_convert_exec_args): take pos and subr arguments and
2216 improve error checking.
2218 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2220 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
2221 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
2222 argument to SCM_ASSERT. Furthermore, the name of the function
2223 should be passed as first argument when signalling
2224 SCM_WNA. (Thanks to Thomas Morgan)
2226 * gsubr.c (scm_gsubr_apply): From Radey Shouman
2227 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
2228 dispatches on the number of actual args has a default case
2229 reporting an internal error. This is a vestige from a version
2230 that mallocated a SCM vector to hold the arguments. In the
2231 current version this check is too late: if it ever happens we will
2232 have already overstepped the bounds of the array.
2234 Also, the patch [...] adds a check for too many actual arguments."
2236 mdj: Removed check for "internal programming error".
2238 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2240 * gh_io.c (gh_write): New function.
2242 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
2243 throw.c (scm_internal_stack_catch): New sibling to the other catch
2244 functions. Code moved from gh_eval.c.
2245 throw.h: Added header.
2246 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
2247 scm_internal_stack_catch.
2249 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2251 * ioext.h: fix up prototypes.
2252 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
2253 Scheme name is now dup->fdes.
2254 (scm_dup_to_fdes): make the second argument optional and
2255 fold in the functionality of scm_primitive_dup.
2256 (scm_primitive_dup): deleted.
2258 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
2260 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
2261 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
2262 ultrix are defined. Use setvbuf instead of setbuf.
2263 (scm_setvbuf): new procedure.
2264 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
2265 (scm_setfileno): moved from ioext.c.
2266 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
2267 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
2269 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2271 * fluids.c (scm_fluid_p): New function.
2272 * fluids.h (scm_fluid_p): New prototype.

2276 * print.c (scm_iprin1): Enter printed structures into the print
2277 state as nested data while they are printed.
2278 (print_state_fluid, print_state_fluid_num): New variables.
2279 (scm_init_print): Initialize them.
2280 (scm_iprin): If print_state_fluid carries a print_state, use that
2281 instead of creating a new one.
2282 (scm_printer_apply, apply_stub, struct apply_data): New
2283 definitions to help with calling printer functions written in
2285 * print.h (scm_printer_apply): New prototype.
2287 * struct.c (scm_print_struct): Use scm_printer_apply to call the
2288 user defined struct printer.
2290 * dynwind.c (scm_dowinds): Handle fluids on the wind list.
2291 * fluids.h (scm_internal_with_fluids, scm_with_fluids,

2298 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
2299 SCM_ASSERT: arg comes before pos.
2301 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2303 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
2304 to a list of length zero correctly.
2306 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2308 Supply an `fgets' method for port objects to do fast line i/o.

2310 * genio.c (scm_gen_read_line): New function.
2311 * fports.c (scm_fgets): New function.
2312 (scm_fptob, scm_pipob): Add scm_fgets method.

2320 Mon Jul 21 04:03:42 1997 Gary Houston <ghouston@actrix.gen.nz>
2322 * ioext.h: removed scm_duplicate_port prototype.
2324 * ioext.c (scm_primitive_dup2): return the new file descriptor
2325 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
2327 (scm_fdopen): bug fix: don't try to make port unbuffered until its
2328 stream has been set.
2329 (scm_duplicate_port): deleted, there's now an implementation in
2331 (scm_primitive_dup2): do nothing if newfd == oldfd.
2333 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
2335 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
2338 * ioext.h: new prototypes.
2339 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
2341 * fluids.c (next_fluid_num): don't do
2342 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
2344 * ports.h: prototypes too.
2345 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
2347 * fports.h: prototype too.
2348 * fports.c (scm_evict_ports): moved from ioext.c.
2350 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2352 * ports.c (scm_close_port): return a boolean instead of unspecified.

2357 and ports (scsh compatible).
2359 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
2362 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
2364 * fluids.c, fluid.h: New files.
2365 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
2366 (modinclude_HEADERS): Added "fluids.h"

2374 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
2375 (scm_make_root): Call scm_copy_fluids to make fluid bindings
2376 unique for the new root when it has a parent.
2378 * smob.h: Include "libguile/print.h" to make scm_print_state
2381 * dynl.c (free_dynl_obj): New function to free the dynamic object
2382 data. (dynl_smob): Use it.
2383 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
2384 the dynamic object data below the linking of the object to avoid
2385 memory leak when the linking code throws an error. Now the code
2386 leaks a whole dynamically linked library when must_malloc throws,
2387 but that should be much less likely.
2389 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
2391 Changes to compile under gnu-win32, from Marcus Daniels:
2392 * stime.c (tzset): If tzset isn't provided, make it a NOP.
2393 (scm_localtime): Change SCM_EOF to SCM_EOL.
2394 (scm_mktime): Likewise.
2395 * socket.c: Don't include sys/un.h unless autoconf tells
2396 us Unix domain sockets are available.
2397 (scm_fill_sockaddr): Ignore Unix domain code.
2398 (scm_addr_vector): Likewise.
2399 (scm_init_addr_buffer): Likewise.
2400 (scm_socketpair): Don't include unless socketpair was

2403 * scmsigs.c (scm_pause): Don't include unless pause was found
2405 * posix.c (scm_getgroups): Don't include unless support function
2406 was found during autoconf (in this case, getgroups).
2407 (scm_setpwent): For setpwent.
2408 (scm_setegid): For setegid.
2409 * net_db.c (scm_inet_netof): Don't include unless support
2410 function was found during autoconf (in this case, inet_netof).
2411 (scm_lnaof): For inet_lnaof.
2412 (scm_inet_makeaddr): For inet_makeaddr.

2424 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
2425 scm_misc_error, not SCM_EOF.
2427 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
2428 arguments for formatting the error message, not SCM_BOOL_F. I
2429 think this is left over from the (eq? '() #f) days.
2431 * read.c (recsexpr): Give this a dummy definition if
2432 DEBUG_EXTENSIONS isn't #defined.
2434 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
2436 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
2439 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>

2446 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
2447 alloca.lo will be included in @LIBLOBJS@. Something better than
2448 this should be possible.
2449 * Makefile.in: Regenerated.
2451 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2453 * simpos.h: prototype for scm_primitive_exit.
2454 * simpos.c (scm_primitive_exit): new procedure, terminates the
2455 process without unwinding the stack.
2457 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
2459 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
2460 argument and logior its components together, so the user doesn't
2461 have to do this explicitly. Also, if regexp/basic is supplied, then
2462 turn off REG_EXTENDED.
2463 (scm_init_regex_posix): New regexp/basic symbol.
2464 (REG_BASIC): #define this if it is not already present.
2466 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2468 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
2469 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
2470 (CLEANFILES): New target, clean versiondat.h, libpath.h.
2471 (DISTCLEANFILES): New target, clean *.x.
2472 * Makefile.in: Regenerated.

2477 years in usage message.
2479 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
2480 * Makefile.in: Regenerated.
2482 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
2483 flag; I don't think we support it.
2484 (scm_make_regexp): Make sure the user doesn't pass the
2487 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
2489 (scm_init_regex_posix): Define constants for the REG_mumble flags;
2490 name them according to the SCSH convention: regexp/mumble.
2492 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
2494 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
2496 * Makefile.am (libpath.h): Include the values of all the standard
2497 Makefile directory variables. Print a message, but don't print
2499 (versiondat.h): Print a message, but don't print all the commands.
2500 * load.c: #include "alist.h".
2501 (init_build_info): New function.
2502 (scm_init_load): Call it.
2503 * Makefile.in: Regenerated.
2505 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
2507 * root.c: Establish a reliable catch-all handler for the new root.
2508 After all the Scheme handler function might signal an error too,
2509 and we don't want to lose that.
2510 (cwdr_inner_body): Renamed from cwdr_body.
2511 (cwdr_outer_body): New function, to establish the user's handler,
2512 and pass control to cwdr_inner_body.
2513 (cwdr): Establish the reliable catch-all handler here, and pass
2514 control to cwdr_outer_body.
2515 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
2516 the user's handler through to cwdr_outer_body.
2517 * throw.c (scm_handle_by_message): Move guts into....
2518 (handler_message): New static function.
2519 (scm_handle_by_message_noexit): New function.
2520 * throw.h (scm_handle_by_message_noexit): New prototype.
2522 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
2523 across this. Only works on GCC. Otherwise, we hope for the best.
2524 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2525 the feeling that real thread systems will not need this...
2527 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2529 Try to detect when people are using one version of libguile and a
2530 different version of ice-9. People have been skewing things and
2531 sending in bug reports.
2532 * Makefile.am (versiondat.h): New file to generate.
2533 * version.c: #include "versiondat.h", to get version info.
2534 (scm_libguile_config_stamp): New function.
2535 * script.c: #include "version.h".
2536 (scm_compile_switches): Call scm_version to get version number.
2537 * scmconfig.h.in, Makefile.in: Regenerated.
2538 * Makefile.in: Regenerated.
2540 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
2541 primitive definitions under their Scheme names.
2543 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2544 1:2. Helps avoid confusion between installed and uninstalled libs.
2546 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2549 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2550 backslash from definition; this should be used like: GDB_INTERFACE;
2552 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2554 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
2555 new port unbuffered until its stream has been set.
2557 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2559 * ports.h: new prototype.
2560 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
2562 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
2564 Make things compile neatly under Sun's C compiler.
2565 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
2566 * extchrs.c (xmbtowc): Make the second arg a normal char, not
2567 unsigned, because that's what the ANSI function takes.
2568 * extchrs.h (xmbtowc): Corresponding change to prototype.
2569 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2571 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2572 argument plain char *.
2573 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2575 * tag.c (scm_tag): Remove unreachable statement.
2576 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2577 top of the word, it should be unsigned.
2579 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2580 is defined, to avoid warnings; it's only used in the
2581 conflict-checking code. Which might go away anyway.
2582 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2583 conditionals; put the label definition in an #if too, to stifle
2586 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2587 ChangeLog-threads in the distribution.
2588 * Makefile.in: Regenerated.
2590 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2592 * guile-snarf.in: Changed regexp to support CPPs that insert
2593 whitespace between lexical tokens (which munges the `%%%' snarf
2596 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2598 * load.c (scm_init_load_path): Append $(datadir)/guile to
2599 %load-path, so modules do not have to be installed in Guile's
2600 current version directory.
2602 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2604 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2605 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2606 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2607 call the sysdep functions with deferred ints.
2608 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2609 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2610 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2613 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2616 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2618 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2620 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2622 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2625 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2627 * eval.c (scm_lookupcar1): New procedure to cope with a race
2628 condition during lookup (when using threads).
2629 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2630 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2633 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2635 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2636 supplied. (Change from Tim Pierce.)
2638 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2640 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2641 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2642 default and not `()'. `#f' is the canonical non-value in Scheme,
2645 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2647 * struct.c (struct_printer): New variable that holds a handle on
2648 the Scheme variable *struct-printer*. This variable can be set by
2649 Scheme code to override the printing of structures.
2650 (scm_print_struct): If struct_printer is set, call it. If it is
2651 not set, or returns #f, print the structure in the old fashion.
2652 Include "eval.h" for scm_apply.
2654 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2656 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2657 scm_struct_i_n_words to get the number of fields, not
2658 -scm_struct_n_extra_words.
2660 On the route to fancier struct printing:
2661 * struct.c (scm_print_struct): New function to print a structure.
2662 Include "genio.h" to support it. This function doesn't do
2663 anything interesting right now, but I think it should be here
2665 * struct.h: Include "print.h" and add prototype for
2667 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2668 print structures ourself.
2670 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2672 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2673 before applying the handler in case it doesn't return.
2675 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2677 * scmsigs.h, async.h: updated.
2679 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2682 * posix.c (scm_uname): interpret only negative values as an error.
2683 Solaris normally returns a positive value.
2685 * script.c (scm_compile_shell_switches): if we are not going into
2686 an interactive repl, set scm_mask_ints to zero so that asyncs can
2689 * simpos.c (scm_system): don't ignore/unignore signals around
2692 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2695 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2696 done in boot-9.scm instead.
2698 * scmsigs.c, async.c: Major rewriting of signal handling code.
2699 (scm_sigaction): new procedure.
2700 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2702 (scm_raise): return unspecified, throw error on failure.
2704 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2706 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2707 feature, to help boot-9.scm decide whether to import the regex
2710 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2712 * eval.c: Include scmconfig.h at the beginning of the file so that
2713 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2716 * regex-posix.c: #include "_scm.h" before conditionally #including
2717 <regex.h>; the former defines HAVE_REGCOMP.
2719 * regex-posix.c: #include <regex.h> conditionally, so the file is
2720 CPP'able (for dependency scanning) even on systems that don't have
2723 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2725 Add new R4RS-compliant syntax for keywords.
2726 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2727 regardless of the setting of the `keywords' read option.
2728 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2729 can be re-read no matter what the setting of the `keywords' read
2732 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2734 Add support for POSIX regular expressions.
2736 * regex-posix.c, regex-posix.h: New files. (Some code
2737 is taken liberally from rx/rgx.c in the old Guile dist.)
2739 * init.c: Include regex-posix.h.
2740 (scm_boot_guile_1): Call scm_init_regex_posix.
2742 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2743 Add regex-posix.[ch] sources.
2744 * Makefile.in: Regenerated.
2746 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2747 to do this automatically? It didn't for me, bleh.)
2749 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2751 * fports.c (print_pipe_port): New function.
2752 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2753 latter doesn't even take the right arguments.
2755 * Makefile.am: Increment shared lib revision number. I think
2756 sometimes the uninstalled Guile finds the installed shared lib;
2757 Gord says doing this might help. As things turned out, I can't
2758 say whether it does.
2759 * Makefile.in: Regenerated.
2761 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2762 passing it as the closure argument to scm_boot_guile. (Bill
2765 * ports.c (print_void_port, putc_void_port, puts_void_port,
2766 write_void_port, flush_void_port, getc_void_port, close_void_port,
2767 noop0): Use ANSI prototypes instead of K&R declarations, so the
2768 initialization of void_port_ptob gets aggressively type-checked.
2769 Fix arguments of print_void_port and write_void_port. (Bill

2803 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2805 * script.c (scm_find_executable): Use prototype-style definition
2806 here; apparently it's not quite right to have const in a prototype
2807 and then use a K&R declaration. I wonder if stuff like this will
2808 go away if we compile with -Wrequire-prototypes, or whatever that
2809 is... (Bernard URBAN)
2811 * scmhob.h: New text from Bernard URBAN.
2813 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2815 * script.c: Don't #define const on hpux. Configure takes care of
2816 this. (Thanks to Larry Schwimmer.)
2818 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2819 decide whether to #include <unistd.h>, instead of listing a bunch
2820 of systems. Don't #include stdio twice. Removed dyked-out
2821 definition of scm_find_impl_file.
2823 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2825 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2826 library version info to 1:0.
2827 * Makefile.in: Regenerated.
2829 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

2833 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2834 throw.c: Update copyright years; these files have been worked on
2835 significantly in 1997, but only had copyright years for 1996.
2836 Also, change name of copyright holder on some from Mikael
2837 Djurfeldt to Free Software Foundation; he has signed papers
2838 assigning the changes to the FSF.
2840 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2841 reason not to give the user the option.
2843 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2844 Return #f on end-of-file when scanning table (i.e. when called
2845 with no arguments). Try to catch errors, when we can.
2846 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2848 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2849 external declarations. These are useful.
2851 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2853 * posix.c: don't include <sys/select.h> or define macros for
2854 select, since they were not used in this file.
2856 * filesys.c (scm_select): make the fifth parameter microseconds,
2857 not milliseconds. let the fourth parameter be either a real value
2858 or an integer or #f. The first, second and third arguments can
2859 now be vectors: the type of the corresponding return set will be
2861 (set_element, get_element): new static procedures.
2863 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2865 * strports.c (scm_eval_string): New function.
2866 (scm_eval_0str): Trivially re-implemented in terms of
2868 * strports.h (scm_eval_string): New extern decl.
2870 * net_db.c (h_errno): Add extern decl for this.
2872 * fports.c (local_pclose): New function.
2873 (scm_pipob): Use it in the initializer here.
2876 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2877 Use a meaningful error message when signalling an error. For
2878 this, scm_gethost must check h_errno rather than errno.
2880 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2882 * Makefile.in: Regenerated, using automake-1.1p.
2884 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2886 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2887 not SCM_UNSPECIFIED.
2889 * script.c (scm_compile_shell_switches): don't append (quit) if
2891 (scm_shell): call scm_exit_status and exit on the result of the
2894 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2896 Ensure that shared substrings are handled properly when passed to
2897 a system call or other foreign function. Many thanks to Tim
2899 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2900 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2901 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2902 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

2917 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2919 * error.c (scm_error): Add newline to error message.

2928 * script.c (scm_ice_9_already_loaded): New variable.
2929 (scm_compile_shell_switches): Use it.
2931 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2933 * filesys.c (scm_input_waiting_p): add missing third argument to
2936 * stime.c (scm_localtime): copy the result of localtime before
2937 calling gmtime in case they share a buffer.
2938 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2941 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2943 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2945 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2947 * Makefile.am (check-local): New target, which causes 'make check'
2948 to run gh_test_c and gh_test_repl, with some trivial input.
2949 * Makefile.in: Rgnrtd.
2951 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2953 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2956 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2958 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2959 sure how this was supposed to work.
2960 (scm_async_click): don't send SCM_TICK_SIGNAL.
2961 (scm_init_async): don't initialize %tick-thunk.
2963 * the following change doesn't affect the Scheme interface:
2964 gc-thunk is called at the end of garbage collection. however it's
2965 no longer implemented by pretending it's a signal.
2967 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2968 system async corresponding to scm_gc_thunk.
2969 * async.h: declare scm_gc_async.
2970 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2971 gc-thunk directly, instead of going through a signal handler.
2972 (scm_gc_async): new variable, points to the GC system-async.
2973 (scm_init_async): save the GC async as scm_gc_async instead
2974 of using system_signal_asyncs.
2975 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2977 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2979 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2980 Don't screw up if we're interrupted.
2981 * Makefile.in: Regeneradet.
2983 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2985 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2987 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2988 we're not using AM_INIT_GUILE_MODULE any more.
2989 * Makefile.in: Reneregated.
2991 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2993 Functions for finding variable bindings, grace à Tim Pierce.
2994 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2995 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2997 Get 'make dist' to work again.
2998 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2999 * Makefile.in: Regenerated, like a surry without a fringe on top.
3001 Changes for reduced Guile distribution: one configure script,
3003 * configure.in, configure: Removed.
3004 * acconfig.h, acinclude.m4: Moved to parent directory, where the
3005 real configure script lives.
3006 * Makefile.in, scmconfig.h.in: Regenerated.
3008 * init.c: #include "script.h", to get prototype for script.c's
3011 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
3013 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
3014 scm_must_malloc, not raw malloc.
3016 * script.c (scm_compile_shell_switches): Dyke out debugging output
3019 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3021 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
3023 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
3024 system has them. Hope this is safe. Previously
3025 sys/timeb.h was included if HAVE_FTIME was defined or if
3026 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
3027 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
3029 * ioext.c (scm_setfileno): add missing third argument to
3030 scm_misc_error call.
3032 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
3034 * eq.c (scm_equal_p): Correctly compare strings of different
3035 varieties. (Thanks to Tim Pierce.)
3037 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
3039 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
3040 #! block comment must occur on a line all by itself.
3042 Move most of the guts of shell command processing into libguile,
3043 so guile.c can be very small (and eventuallly auto-generated. (I
3044 mean, generated mechanically, not self-generated. Hmm.))
3045 * guile.c, script.c, script.h: New source files.
3046 * init.c (scm_boot_guile_1): Call scm_init_script.
3047 * libguile.h: #include "script.h".
3048 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
3049 targets, for new executable.
3050 (libguile_la_SOURCES): Mention script.c.
3051 (modinclude_HEADERS): Add script.h.
3052 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
3053 not dynamic linking is enabled. This is because we're generating
3054 executables now. Move CY_AC_WITH_THREADS call after those, so the
3055 values of cy_cv_threads_libs captures the libs chosen above.
3056 * Makefile.in, configure, aclocal.m4: Regenerated.
3058 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
3059 We don't maintain this interface any more, and it just confuses
3062 * alloca.c: #include <scmconfig.h>, not <config.h>.
3063 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
3064 it'll get included in disties.
3066 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
3068 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
3069 be distributed, because they confuse people.
3070 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
3072 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
3074 * configure.in: check for presence of gethostent (not present on
3075 OpenBSD by default).
3076 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
3077 * configure, scmconfig.h.in: Regenerated.
3079 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
3081 * backtrace.c (scm_backtrace): Split message string across
3082 newlines properly. GCC is more tolerant of this than other

3087 Merge threads directory into libguile.
3088 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
3089 threads.h: New source files.

3091 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
3093 (modinclude_HEADERS): Add threads.h, coop-defs.h.
3094 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
3095 coop-threads.c.cygnus, coop-threads.h.cygnus.
3096 * configure.in: If we're using threads, include threads.o in
3098 * _scm.h, libguile.h: threads.h lives in this directory now.
3099 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
3100 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
3101 currently used, but brought along for information's sake.
3102 * ChangeLog-threads: log from old 'threads' directory.
3103 * Makefile.in, configure: Rebuilt.
3105 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
3107 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
3110 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
3112 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
3114 Merge GH interface library into libguile.

3116 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
3117 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
3118 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
3120 (EXTRA_libguile_la_SOURCES): ... here.
3121 (pkginclude_HEADERS): Add variable, to get gh.h installed.
3122 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
3123 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
3124 New variables, describing how to build the gh test programs.
3125 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
3126 build the test programs, and we probably should have been linking
3127 libguile.la against them all along, to support AIX shared libs.
3128 Add cflags for threads to CFLAGS; add libs for threads to new
3129 variable THREAD_LIBS, used in Makefile.am.
3130 * ChangeLog-gh: log from old `gh' subdirectory.
3131 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
3133 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
3135 * acconfig.h: Undo change of Apr 9; including the definition of
3136 PACKAGE in the guile headers conflicts with applications' own
3138 * scmconfig.h.in: Regenerated.
3140 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

3147 when PROC is receiving no arguments.
3149 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
3151 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
3152 have S_IFSOCK. This is the case under Ultrix.
3154 * posix.c (scm_status_exit_val, scm_status_exit_val,
3155 scm_status_term_sig, scm_status_stop_sig): Modified to work with
3156 Ultrix versions of WIFSTOPPED, etc., which assume that their
3157 arguments are lvalues (hmm).
3159 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
3161 * eval.c: Doc fixes.
3163 * throw.c: Doc fixes; rearranged.
3165 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.

3169 * acconfig.h: Added entry for PACKAGE.
3170 * scmconfig.h.in: Regenerated.
3172 Changes to work with automake-1.1n, which has better libtool support.
3173 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
3174 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
3176 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
3178 * Makefile.in: Rebuild.
3180 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3182 * stime.c (scm_mktime): take an optional zone argument.
3183 (scm_localtime): check putenv return value.
3184 (scm_strftime, scm_strptime): moved from posix.c. move #include
3186 stime.h, posix.h: update prototypes.
3187 (bdtime2c, setzone, restorezone): new static procedures.
3188 (scm_mktime, scm_strftime): use them.
3189 (scm_strftime): don't call mktime before strftime. Use
3190 filltime for return value.
3191 (filltime): convert NULL zname to #f.
3192 (scm_strptime): return a count of characters consumed, not
3193 the remaining string.
3195 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3197 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
3198 (scm_mktime): likewise.
3200 Uncomment localtime and mktime.
3202 * configure.in: add AC_STRUCT_TIMEZONE.
3204 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3206 * stime.c (scm_init_stime): don't define ticks/sec.
3207 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
3208 return value problem and is still portable.)
3210 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3212 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
3213 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
3214 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
3215 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
3216 cpp_err_symbols.c): Corresponding changes.
3217 * Makefile.in: Regenerated.

3221 * posix.c (scm_putenv): don't check HAVE_PUTENV.
3222 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.

3224 * putenv.c: new file, from sh-utils 1.12.
3226 * posix.c (scm_environ): use malloc in place of scm_must_malloc
3227 since allocation isn't for Scheme objects.
3228 (scm_putenv): copy strings before placing in the environment.
3230 * stime.c (scm_current_time): throw an error if time returns -1,
3231 instead of returning #f.
3232 (scm_get_internal_real_time, scm_get_internal_real_time): use
3233 scm_long2num for return value instead of SCM_MAKINUM.
3235 * stime.h: prototypes updated.
3237 * stime.c (scm_time_in_msec): apparently unused, deleted.
3239 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
3241 * configure.in: check for gettimeofday.
3243 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
3244 which may be more usefully portable than a gettimeofday interface.
3246 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
3248 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not

3254 * stime.c (filltime): recovered static procedure.
3255 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from

3259 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
3261 * posix.c (scm_mknod): split the mode argument into type and perms
3262 arguments, like the extra fields returned by stat.
3264 * fports.c (scm_pipob): set the close, free and print procedures.
3265 (scm_close_pipe): new procedure.
3267 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
3268 define them in boot-9.scm
3270 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3272 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
3273 wan't defined. Don't include fd.h.
3275 * Previously fd.h was regenerated whenever configure was run,
3276 forcing a couple of files to be recompiled.
3278 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
3279 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
3280 Check for _fileno as well as _file.
3282 * ioext.c: don't fd.h.
3283 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
3286 * Change the stratigy for getting information about errno
3287 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
3288 generating lists of symbols during the build process, which will
3289 not always work, include comprehensive lists in the distribution.
3290 To help keep the lists up to date, the "check_signals" and
3291 "check_errnos" make targets can be used.
3293 * configure.in: don't check for a command to extract errno codes.
3294 * Makefile.am: update file lists, remove errnos.list and errnos.c
3295 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
3296 check_errnos targets.
3297 (CLEANFILES): remove errnos.c and errnos.list, add
3298 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
3299 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
3300 * errnos.default: deleted.
3301 * cpp_signal.c: new file.
3302 * cpp_errno.c: renamed from errnos_get.c.
3303 * cpp_err_symbols, cpp_sig_symbols: new files.
3304 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
3305 * error.c (scm_init_error): #include cpp_err_symbols instead of
3307 * posix.c (scm_init_posix): don't intern signal symbols. #include
3310 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
3312 * strop.c (scm_i_index): allow the lower bound to be equal to the
3313 length of the string, so a null string doesn't always give an error.
3315 * posix.h: new prototypes.
3316 * posix.c (scm_status_exit_val, scm_status_term_sig,
3317 scm_status_stop_sig): new functions, as in scsh. They break down
3318 process status values as returned by waitpid.
3320 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
3322 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
3323 configure doesn't know about it.
3325 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3327 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
3329 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
3330 which defines C variables with global linkage.
3332 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3334 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
3337 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
3339 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
3340 has time to check why this doesn't work well with continuations.
3342 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
3344 * Fix shell syntax error; some shells won't tolerate
3345 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
3347 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3349 * posix.c (scm_uname): throw an error if uname fails instead
3352 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
3354 * error.c (err_head, scm_errno, scm_perror): obsolete procedures

3361 * acconfig.h: Removed PACKAGE.
3363 * scmconfig.h.in: Regenerated.
3365 * snarf.h: g++ says it's non-portable not to specify the first
3366 argument in a varargs declaration. I introduced the first
3367 argument by using preprocessor conditionals.
3369 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
3371 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
3372 (scm_freopen): use RO string macros for filename and modes.
3373 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.

3376 (scm_mknod): use RO string macros for path.
3378 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
3379 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
3381 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
3382 use SCM_ROSTRINGP and SCM_ROCHARS.

3386 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
3389 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
3390 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
3391 support for byte vectors.
3393 * print.c (scm_iprin1): Limit number of vector elements printed
3394 according to pstate->length.
3396 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>

3401 * error.h: prototype for scm_error_scm.
3403 * error.c (scm_error_scm): new procedure, reimplements scm-error
3404 in C and uses scm_error.
3406 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3408 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
3409 pointer to the Scheme variable read-hash-procedures and intern it
3410 in scm_init_read. Modify scm_read_hash_extend and
3411 scm_get_hash_procedure to use the pointer.
3413 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3415 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
3416 (SCM_KEYWORD_STYLE): defined.
3418 * read.c (scm_read_opts): add a keywords option. This isn't a
3419 boolean option, in case someone wants to add support for DSSSL
3421 Setup scm_keyword_prefix symbol.
3422 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
3424 I've left keyword support disabled by default, since it doesn't
3425 seem to break the module system and it gives R4RS standard behaviour.
3426 It can be reactivated with (read-set! keywords 'prefix).
3428 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3430 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
3431 before constructing arbiter.
3433 * eval.c (scm_m_define): Bugfix: Check that the object is a
3434 closure before setting the procedure property!
3436 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
3438 * ports.c: Removed `ungetc-char-ready?'.
3440 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
3442 * read.c (scm_init_read): intitialise scm_read_hash_procedures
3443 (idea from Mikael: make it a pair so scm_permanent object only
3445 (scm_read_hash_extend): don't call scm_permanent_object.
3446 (ideas from Mikael): if chr is already in the list, replace its
3447 procedure instead of appending it again. If proc is #f, remove
3449 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
3451 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
3453 * gdbint.c (gdb_read): update scm_lreadr usage.
3455 * load.h: update prototypes.
3457 * load.c (scm_primitive_load, scm_read_and_eval_x,
3458 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
3460 * read.h: add prototype for scm_read_hash_extend. Change args for
3463 * read.c (scm_read_hash_procedures): new variable.
3464 (scm_read_hash_extend): new procedure.
3465 (scm_get_hash_procedure): new procedure.
3466 (scm_lreadr): use scm_get_hash_procedure instead of an argument
3467 for extended # processing.
3468 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
3469 scm_read_token): remove case_i, sharp arguments. Change callers.
3471 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
3473 * read.h (SCM_N_READ_OPTIONS): increase to 3.
3474 (SCM_CASE_INSENSITIVE_P): define.
3476 * read.c: add case-insensitive option to scm_read_opts.
3477 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
3478 to determine whether to convert symbol case.
3479 (default_case_i): definition removed.
3480 * read.c (scm_read_token): if case_i, downcase ic before doing
3483 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3485 * configure.in: Added configuration option `guile-debug'.
3486 Configure with --enable-guile-debug if you want a bunch of extra
3487 functions used for debugging when developing Guile.
3489 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3491 * procs.c (make-cclo): New undocumented debugging procedure: Make
3492 compiled closure with internal procedure PROC and length LENGTH.
3493 Only compiled if GUILE_DEBUG is defined.
3495 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3497 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3499 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3501 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3502 with 3 or more args internally to the evaluator.
3504 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3506 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3507 with 3 or more args internally to the evaluator. This is mainly
3508 because we don't want to pass entry and exit points of the
3509 debug support twice, but it also seems to increase the speed of
3510 the evaluator for such calls (e. g. (+ 1 2 3)).
3512 * backtrace.c (scm_display_application): New procedure:
3513 display-application; Set fancy printing parameters individually
3514 for different types of display (backtrace, error, application).
3515 (These should of course be customizable!)
3517 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3518 clear the CHECK-flags.
3520 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3522 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3524 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3526 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3527 from pairs with a GLOC in the car.
3529 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3530 otherwise `symbol-hash' will behave badly.
3531 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3532 we get segmentation fault!
3534 * symbols.c: Added #include "weaks.h". New functions:
3535 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3536 moved to an extraneous library when we split libguile.)
3538 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3540 * filesys.c (scm_stat): stat now takes fport arguments too as
3541 documented in the manual.
3543 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3545 * debug.c (scm_single_step): Bugfix: Call continuation with
3546 scm_call_continuation instead of throwing to it.
3548 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3550 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3551 argument wasn't declared to be optional.
3553 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3555 * stime.c (scm_init_stime): Add feature "current-time".
3557 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3559 * throw.h: prototype for scm_exit_status.
3560 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3561 args to derive an exit status. Allows (quit) to work from a
3563 (scm_exit_status): new function.
3566 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3568 * eval.c (scm_deval): Removed some old code.
3569 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3571 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3574 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3577 * procs.c: Introduce the existent C function scm_thunk_p at the
3578 Scheme level as well.
3580 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3582 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3583 used from C to easily lookup the value of a symbol in the current
3586 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3588 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3589 scm_init_unif in this file. This will also fix a previous problem
3592 * configure.in: Added AM_MAINTAINER_MODE
3594 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3596 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3599 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3601 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3602 source files that are not always included in libguile but should
3603 have their dependencies calculated by automake. This variable is
3604 recognized by automake, no further magic is needed.
3605 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3606 to deal exclusively with *.lo files, as it seems. The *.o files
3607 are built automatically when the corresponding *.lo file gets
3610 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3612 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3615 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3617 * unif.c (scm_array_set_x): minor change to argument error checking.
3619 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3621 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3622 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3623 They should only be included in the library at configure.in's
3625 (libguile_la_LDADD): Include the appropriate .lo files here.
3626 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3627 so we know when to build them (and their .lo bretheren).
3628 * configure.in (LIBLOBJS): New substituted variable. We let
3629 configure decide which .o files to include in LIBOBJS, and then
3630 put the corresponding list of .lo files in LIBLOBJS. The latter
3631 is what we pass to libtool.
3632 * Makefile.in, configure: regenerated.
3634 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3636 * symbols.c (scm_sysintern0): New function. Contains the core of
3637 old scm_sysintern but doesn't take a second value argument.
3638 (scm_sysintern): Now uses scm_sysintern0.
3639 (scm_sysintern_no_module_lookup): Renamed to
3640 scm_sysintern0_no_module_lookup and doesn't take a second value
3641 argument any longer.
3643 * symbols.h (scm_sysintern0: Added declaration.
3645 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3646 scm_sysintern when interning option keys. Otherwise we risk
3647 destroying the values of already interned variables.
3649 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3650 scheme-level boolean (use SCM_NFALSEP).
3652 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3654 (scm_backtrace): New function. (C version of old function from
3655 boot-9.scm) Motivation: Make it possible to display backtraces
3656 without depending on boot-9.scm. (I'm uncertain if this
3657 motivation is good enough...)
3659 * root.h (scm_root_state): Add member the_last_stack_var.
3660 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3662 * root.c (mark_root): Mark scm_the_last_stack_var.
3664 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3667 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3669 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3670 1. mark_lazy_catch didn't mark the smob.
3671 2. Both functions above have standard variants:
3672 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3673 free_lazy_catch --> scm_free0.
3675 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3677 * throw.c (scm_internal_lazy_catch): New function.
3678 (scm_lazy_catch): Rewritten to use it.
3679 (scm_ithrow): Handle the new lazy catch representation.
3680 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3681 that doesn't have a jmpbuf is a lazy catch clause.
3682 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3683 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3684 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3686 (scm_init_throw): Register the new lazy-catch smob type.
3687 * throw.h (scm_internal_lazy_catch): decl for new function.
3689 * throw.c (scm_internal_catch): Doc fixes.
3691 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3692 configure.in. Including this might cause problems if applications
3693 that link against libguile include their own copies of alloca, but
3694 if they're using autoconf, they should be adding libguile to LIBS
3695 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3696 the copy in libguile, and things will be okay. (I think.)
3698 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3700 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3702 strop.h: move prototypes too.
3704 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3706 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3709 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3710 etc. I deleted them from filesys.c long ago, but didn't
3711 notice they were here too (although ineffective since
3712 sys/stat.h wasn't included).
3714 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3716 * eval.c: Don't define alloca in GCC case. gcc will automatically
3717 use __builtin_alloca if appropriate.
3719 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3721 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3722 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3723 that values of automatic variables are preserved. See comments
3724 for safe_setjmp for details.
3726 Change from Thomas Morgan:
3727 * variable.c: Include eq.h.
3728 (var_equal): New function.
3729 (variable_smob): Use var_equal as the discriminator for variables.
3731 * throw.c (s_throw): Remove extraneous declaration.
3733 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3734 * eval.c: Add necessary CPP cruft to support that.
3735 * configure, Makefile.in, scmconfig.h.in: regenerated.
3737 Change from Thomas Morgan:
3738 * procprop.c (scm_procedure_properties): Convert the Scheme
3739 boolean returned by scm_procedure_p into a C boolean before using
3740 it as a condition for SCM_ASSERT.
3741 (scm_procedure_property): Likewise.
3743 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3744 indications of Unixness.
3747 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3749 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3751 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3753 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3754 "unknown # object" error messages.
3756 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3757 (scm_i_index) and declare it static. Add a 'direction' argument
3758 to indicate what way the search should go.
3759 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3761 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3762 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3764 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3766 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3768 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3769 to avoid clash with various scsh forks.
3771 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3773 The following two changes (ramap.c, throw.c) are motivated by the
3774 apparent unportability of forward declarations of static arrays of
3775 the form `static foo bar[];'.
3777 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3778 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3780 * throw.c (scm_throw): Moved above scm_ithrow.
3782 * options.h: Removed the extern declarations of scm_yes_sym and
3783 scm_no_sym since these are static.
3785 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3787 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3789 * Makefile.am: remove AWK=@AWK@.
3790 Add a rule for generating errnos.list.
3791 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3793 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3794 don't extract errnos, just set a variable (avoids the
3795 need to recompile error.c just because configure is run.)
3797 * unif.h: update prototypes.
3798 * unif.c (scm_uniform_array_read,write): change the offset and
3799 length arguments to start and end, for consistency.
3801 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3803 * ioext.h: update prototypes.
3804 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3805 scm_read_line_x, it's a more general procedure using an
3806 interface from scsh. read-line and read-line! are now defined
3808 Note that the new read-line trims the terminator
3809 by default, previously it was appended to the returned string. An
3810 optional argument specifies how to process the terminator (scsh
3811 compatible). For the old behaviour: (read-line port 'concat).
3812 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3813 returns a pair, but is converted to multiple values if the scsh
3816 socket.h: update prototypes.
3817 * socket.c (scm_recvfrom): for consistency with other procedures,
3818 take start and end as separate optional arguments.
3819 (scm_recv, scm_recvfrom): don't allow the second argument
3820 to be a size, only a buffer. Change the scheme names to
3821 recv! and recvfrom!. Don't return the buffer.
3823 * ioext.h, posix.h: move prototypes too.
3824 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3825 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3826 "read.h" and "unif.h".
3827 * ioext.c: include "chars.h"
3829 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3831 * dynl.c: The dynamic linking and module registration functions
3832 are now defined even when dynamic linking is not available for the
3833 host system. Some of their functionality can be done without
3834 dynamic linking; when it's really needed, they throw errors.
3836 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3838 * configure.in: Only define DYNAMIC_LINKING when one of the system
3839 dependent functions is detected.
3840 * dynl.c (scm_dynamic_func): New function to get the address of a
3841 function in a dynamic object.
3842 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3843 produced by scm_dynamic_func as the thing to call.
3845 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3847 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3848 (scm_register_module_xxx, scm_registered_modules,
3849 scm_clear_registered_modules): New functions.
3851 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3853 * symbols.c (scm_sysintern): Renamed to
3854 scm_sysintern_no_module_lookup.
3855 (scm_sysintern): New function to take the place of the old
3856 scm_sysintern. It uses the current toplevel lookup closure to give
3857 the symbol its value. This is a temporary hack to put packages
3858 like gtcltk into their own module.
3859 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3860 us whether `scm_top_level_lookup_closure_var' has been initialized
3862 * eval.c (scm_init_eval): Set it.
3864 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3866 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3867 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3869 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3871 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3872 scm_sys_dup): deleted: FD capability will be added to other
3874 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3875 scm_fd_free, fd_smob, scm_intern_fd.
3876 (scm_open): renamed from scm_sys_open. Return a port instead of
3877 an FD object. Make the mode argument optional.
3878 (scm_sys_create): deleted, it's just a special case of open.
3879 (scm_init_filesys): move interning of constants O_CREAT etc.,
3880 here (were previously using SCM_CONST_LONG macro).
3881 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3883 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3884 include "fports.h" and <stdio.h>
3885 (scm_stat, scm_select): don't support FD objects.
3887 * error.h: adjust scm_syserror_msg prototype.
3888 * error.c (scm_syserror_msg): take an extra argument for errno.
3889 Using the global value didn't always work, since it could be
3890 reset by procedure calls in the message or args arguments.
3892 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3893 I don't understand why the check was there (and what about the
3896 * strop.c (scm_string_copy): allow shared substrings to be copied.
3898 * unif.h: corresponding change to prototypes.
3899 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3900 recognize two new optional arguments: offset and length. Allow
3901 the port argument to be an integer (file descriptor, for scsh).
3902 Include <unistd.h> for "read" prototype.
3904 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3906 * socket.c: don't include filesys.h.
3908 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3910 * Makefile.am: add AWK=@AWK@ (?)
3912 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3914 Add a rule to generate errnos.c from errnos.
3915 * error.c (scm_init_error): include errnos.c.
3916 * errnos_cnvt.awk: new file, converts the list of errno codes to
3918 * errnos_get.c: new file.
3919 * errnos.default: new file, contains errnos to try if they can't
3920 be extracted from errno.h.
3921 * configure.in: if using GCC, try and extract errno codes from
3925 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3927 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3928 * Makefile.am: Made libguile into a libtool library.
3929 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3930 Set libtool_libs to indicate that libguile is a libtool library.
3931 See guile/ChangeLog for details.
3932 * .cvsignore: ignore "*.lo", the libtool library objects.
3934 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3936 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3937 use htons in getservbyport argument.
3939 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3941 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3942 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3945 * objprop.c (scm_object_property): No need to take the CDR of the
3946 value returned by scm_object_properties, since Aug 20 change.
3948 * configure.in: When checking for struct linger, #include
3949 <sys/types.h> as well as <sys/socket.h>. I've never known
3950 <sys/types.h> to cause any portability problems, and Solaris's
3951 <sys/socket.h> needs it.
3952 * configure: Rebuilt.
3954 I think the Sun compiler has chosen a perverse way to interpret
3955 ANSI declarations combined with K&R definitions. We'll
3956 appease it a little bit. But when it invades France, we fight.
3957 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3958 * print.h (scm_iprlist): Here too.
3959 * numbers.c (scm_divbigdig): Change definition to match
3960 declaration in numbers.h.
3961 * unif.c (scm_makflo): Change definition to match declaration in
3964 * init.c (scm_boot_guile): Don't return the value of
3965 scm_boot_guile_1. This function doesn't return a value;
3966 scm_boot_guile_1 doesn't return a value (or return at all).
3968 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3971 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3972 compile. I have a feeling this function is a bad idea anyway ---
3973 one should always test for features, not systems.
3975 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3976 semicolons. Only pure luck kept this from being noticed earlier.
3978 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3980 * socket.c (scm_recvfrom): Added missing semicolon.
3982 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3984 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3985 the buffer and start and end positions for scsh networking
3988 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3990 * configure.in: Revert previous change to this file; the problem
3991 is due to transient automake weirdness.
3992 * configure: Rebuilt.
3994 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3995 PLUGIN/guile.libs. configure generates the latter from the former.
3996 * Makefile.in: Rebuilt.
3998 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3999 need this if we install scripts, like guile-snarf.
4000 * configure: Rebuilt.
4002 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
4004 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
4006 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
4008 * socket.c (scm_addr_vector): fix faulty scm_listify.
4010 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
4012 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
4013 style block comment is no longer considered an error.
4015 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
4017 * PLUGIN/guile.libs.in: New file.
4018 * PLUGIN/guile.libs: Removed from repository.
4019 * configure.in: Create PLUGIN/guile.libs from
4020 PLUGIN/guile.libs.in. This is for including additonal libraries
4021 needed for dynamic linking.
4022 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
4023 instead of PLUGIN/guile.libs.
4025 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
4027 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
4029 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
4030 occurrences of the given element from the list, not just the
4031 first. This is how the Emacs Lisp functions behave, how the
4032 analogous Common Lisp functions behave, and (I believe) how the
4033 older Maclisp functions worked. I realize that this change may
4034 break code, but it seemed better to break it before the Guile
4037 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
4038 Their prototypes were already present in gc.h, but they weren't
4040 (scm_init_storage): Initialize scm_protects.
4041 * root.c (scm_protects): New element of scm_sys_protects.
4043 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
4045 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4047 * libguile.h: Added #include "libguile/net_db.h".
4049 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
4050 30 change. That file is only meant for communication between the
4051 configuration process and load.c. If code linked against libguile
4052 wants to get at the paths mentioned in libpath.h, it can call
4053 functions declared in load.h.
4055 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4057 * libguile.h: Removed #include "libguile/fdsocket.h"
4059 * net_db.c: Added #include <sys/socket.h>.
4061 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
4063 * filesys.c (scm_input_waiting_p): use select in preference to
4064 FIONREAD, since the latter doesn't detect EOF.
4065 Throw error if neither select nor FIONREAD available.
4067 * socket.c (scm_connect): take a port, not a fd object.
4068 (scm_fill_sockaddr): throw an error if fam is not recognised.
4069 (scm_bind): use scm_fill_sockaddr.
4070 (scm_listen): take a port, not a fd object.
4071 (scm_accept): take and return a port. return #f in the car if
4072 address can't be got
4073 (scm_sock_fd_to_port): new procedure.
4074 (scm_socket): use scm_sock_fd_to_port.
4075 (scm_addr_vector): throw error if unrecognised address type.
4076 take an extra argument with the calling procedure name.
4077 (scm_getsockname): take a port. return #f if address can't be got.
4078 (scm_getpeername): take a port. return #f if address can't be got.
4079 (scm_recvfrom): take a port. return #f for address component if can't
4081 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
4082 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
4084 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
4086 * throw.c (scm_internal_catch): Make body funcs and handler funcs
4087 use separate data pointers, to allow them to be designed
4088 independently and reused.
4089 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
4090 Renamed from catch_body, catch_handler, and uncaught_throw; made
4092 (struct scm_catch_body_data): Renamed from catch_body_data; moved
4094 (scm_catch): Use the above.
4095 (scm_throw): Don't bother printing a message for an uncaught
4096 throw; we establish a default handler in init.
4097 * throw.h (scm_internal_catch): Prototype updated.
4098 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
4100 (struct scm_body_thunk_data): New structure, used as data
4101 argument to scm_body_thunk.
4102 * init.c (struct main_func_closure): New structure, packaging up
4103 the data to pass to the user's main function.
4104 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
4105 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
4106 scm_internal_catch to establish a catch-all handler, using
4107 scm_handle_by_message. This replaces the special-case code in
4109 (invoke_main_func): Body function for scm_internal_catch; invoke
4110 the user's main function, using the main_func_closure pointer to
4111 decide what to pass it.
4112 * root.c (struct cwdr_body_data): Remove handler_proc member.
4113 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
4114 (cwdr_handler): Removed.
4116 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4118 * socket.h (SCM_P): update bind prototype.
4119 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
4120 include "feature.h".
4121 (scm_socket): return a port, not a file descriptor object.
4122 include "fports.h" and <unistd.h>
4123 (scm_bind): take a port, not a file descriptor object.
4124 take an extra argument for address args.
4126 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
4127 INADDR_NONE, INADDR_LOOPBACK.
4129 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4131 * init.c: include net_db.h and not fdsocket.h.
4132 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
4134 * Makefile.am: corresponding changes.
4135 * socket.h: renamed from fdsocket.h, fix names.
4136 * net_db.h: renamed from socket.h, fix names.
4137 * socket.c: renamed from fdsocket.c.
4138 remove _sys from procedure names.
4139 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
4140 add "socket" to features list.
4141 * net_db.c: renamed from socket.c.
4142 remove _sys from procedure names.
4143 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
4144 add "net-db" to features list.
4145 include "net_db.h". don't include <sys/socket.h> or
4148 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4150 * tags.h (scm_tags): Removed comma at end of last enumerator.
4152 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
4154 Don't use GCC extensions to allocate space for debugging frames.
4155 (Here he goes again! Why do we put up with this?!)
4156 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
4157 an scm_debug_info structure, not an in-line array of them. Add
4158 'info' member, to say how many vect elements we've used, for eval
4160 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
4161 a new variable debug_info_end to mark the end of vect, instead of
4162 the address of the 'info' pointer itself.
4163 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
4164 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
4165 (SCM_APPLY): Explicitly allocate space for debug.vect.
4166 * debug.c (scm_m_start_stack): Same, for vframe.vect.
4167 * stacks.c: Adjusted for new debug frame structure.
4168 (RELOC_INFO, RELOC_FRAME): New macros.
4169 (stack_depth, read_frames): Use them, and new scm_debug_frame
4170 element 'info', instead of magically knowing that eval frames have
4171 an info pointer sitting after vect.
4172 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
4174 (scm_init_stacks): Formatting tweaks.
4176 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
4178 Give GCC more control flow information, so it can be sure that
4179 variables aren't used uninitialized.
4180 * error.h (scm_error, scm_syserror, scm_syserror_msg,
4181 scm_sysmissing, scm_num_overflow, scm_out_of_range,
4182 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
4183 scm_misc_error): Tell GCC that these functions never return.
4184 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
4185 out the field type, call abort if SCM_ASSERT returns, to placate
4187 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
4188 scm_wta ever returns. We can't handle this case anyway, and this
4189 gives the optimizer more information.
4190 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
4191 scm_wta ever returns.
4193 In some cases, the code is fine, but GCC isn't smart enough to
4194 figure that out; this usually happens when one variable is only
4195 initialized and used when a particular condition holds true, and
4196 we know that condition will never change within a given invocation
4197 of the function. In this case, we simply initialize the variables
4198 to placate the compiler, hopefully to a value which will cause a
4199 crash if it is ever actually used.
4200 * print.c (scm_iprin1): Initialize mw_pos.
4201 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
4202 * throw.c (scm_ithrow): Initialize dynpair.
4203 * unif.c (scm_uniform_vector_ref): Initialize cra.
4204 * struct.c (init_struct): Initialize prot.
4205 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
4207 * strports.c (scm_eval_0str): Don't return uninitialized garbage
4208 if EXPR contains no expressions.
4210 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
4212 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
4213 cause an infinite loop (???). So much for the algebraic
4214 equivalency of variable-sized arrays and alloca...
4216 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
4218 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
4219 a SCM boolean, not a C boolean.
4221 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
4223 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
4224 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
4225 rules for raising scm_mtrigger. Previously, unfortunate but not
4226 unlikely circumstances could result in almost constant invokation
4227 of the gc. Now, this situations should be less likely, but they
4228 are not prevented completely.
4230 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
4232 * numbers.c (scm_fuck): Procedure removed; looks like old test
4234 * numbers.h: Prototype removed.
4236 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
4238 * debug.h (scm_debug_frame): Change `vect' member from an in-line
4239 array to a pointer, to match my Nov 21 change in eval.c.
4241 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4243 * libguile.h: Added #include "libguile/backtrace.h", #include
4244 "libguile/stacks.h".
4246 * strings.c (scm_string scm_make_string scm_string_ref
4247 scm_string_set_x scm_string_equal_p scm_string_append):
4248 Bugfix according to scm patch from Aubrey Jaffer:
4249 Corrected long-standing
4250 (not (eqv? (integer->char 128)
4251 (string-ref (make-string 1 (integer->char 128)) 0)))
4252 bug found by John Kozak <jk@noontide.demon.co.uk>.
4254 * strports.c, strports.h: Make scm_eval_0str return the value of
4255 the last expression evaluated (previously, it returned void).
4257 * strports.c, strports.h: New function: scm_read_0str. Does what
4260 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4262 * simpos.c (scm_getenv): return #f if string can't be found in the
4263 environment instead of throwing an exception, for compatibility
4264 with numerous other systems.
4266 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
4268 * Makefile.am (.c.x): Use guile-snarf.
4269 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
4271 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
4273 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4275 * backtrace.c (scm_display_error_message): Made non-static, and
4276 renamed from display_error_message.
4277 * backtrace.h (scm_display_error_message): Added extern decl.
4278 * throw.c (uncaught_throw): Use it to display the error message.
4280 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
4282 * inet_aton.c: Use #if 0, not #ifdef 0.
4284 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
4286 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
4287 to convert the returned value.
4288 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
4289 the offset argument.
4291 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4293 Add new interface to catch/throw, usable from C as well as
4295 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
4296 (scm_internal_catch): New function, replaces...
4297 (scm_catch_apply): Deleted.
4298 * throw.c (scm_catch_apply): Deleted; replaced with a more general
4299 mechanism which is a bit more code, but can be used nicely from C
4300 and implement the Scheme semantics as well.
4301 (scm_internal_catch): This is the replacement; it's named after
4302 the analogous function in Emacs.
4303 (scm_catch): Reimplemented in terms of the above.
4304 (struct catch_body_data, catch_body, catch_handler): New
4305 functions, used by scm_catch.
4306 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
4307 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
4308 support for new cwdr.
4310 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
4313 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
4315 * acconfig.h: Added DYNAMIC_LINKING symbol.
4316 * configure.in: Add option and checks for dynamic linking.
4317 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
4318 dynl.h: New files for dynamic linking support.
4319 * Makefile.am (libguile_a_SOURCES):
4321 (modinclude_HEADERS): Added "dynl.h".
4322 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
4324 * init.c (scm_boot_guile_1): Call
4325 scm_init_dynamic_linking to initialize dynamic linking support.
4327 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
4329 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
4330 (as we Schemers say). It needs to be global, so that I can tweak
4331 it for the proper operation of unexec.
4332 (scm_boot_guile_1_live): New variable, see above.
4334 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
4336 * guile-snarf.sh: Removed.
4337 * PLUGIN/guile.libs: Added dependency for -lm.
4338 * acinclude.m4: Renamed from aclocal.m4.
4339 * PLUGIN/greet: Removed.
4340 * Makefile.am, aclocal.m4: New files.
4341 * configure.in: Updated for Automake.
4343 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
4345 * eval.c (scm_definedp): Use top_level_lookup_closure_var
4346 and not top_level_lookup_thunk_var.
4348 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
4350 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
4352 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
4354 * eval.c (scm_definedp): Incompatibly changed to be a builtin
4355 Scheme function, instead of syntax. Single argument is now a
4358 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4360 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
4361 scm_ra_divide): Properly terminate statements passed as arguments
4362 to IVDEP macros. (Thanks to Bernard Urban.)
4364 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
4365 with non-constant sizes. (Thanks to Bernard Urban.)
4367 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4369 It's an "eval closure", not an "eval thunk." A thunk is a
4370 function of no arguments.
4371 * root.h (struct scm_root_state): Renamed
4372 top_level_lookup_closure_var from top_level_lookup_thunk_var.
4373 (scm_top_level_lookup_closure_var): Renamed from
4374 scm_top_level_lookup_thunk_var.
4375 * root.c (mark_root): Uses changed.
4376 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
4377 * init.c (scm_start_stack): Uses changed.
4378 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
4379 Change scheme-visible name to *top-level-lookup-closure* from
4380 *top-level-lookup-thunk*.
4382 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
4384 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
4385 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
4387 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
4389 * gc.c (struct scm_heap_seg_data): Doc fixes.
4391 * gc.c (scm_gc_sweep): Empty all segments' freelists before
4392 sweeping. Then, prepend each segment's free cells to its
4393 freelist, rather than wiping out the old value. (Thanks to Marius
4396 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
4397 scm_check_freelist, scm_debug_newcell): New functions and
4398 variables, for debugging freelist problems.
4399 * pairs.h (SCM_NEWCELL): New debugging version added.
4400 * gc.h (scm_debug_newcell): Added extern declaration, used by
4401 debugging version of SCM_NEWCELL.
4403 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4405 On some systems <libc.h> conflicts with <unistd.h>, and should not
4406 be #included at all.
4407 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
4408 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
4409 * configure.in: Call it.
4410 * posix.c, filesys.c: Use its results to decide whether or not to
4412 * configure, scmconfig.h.in: Rebuilt with autoconf and
4415 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4417 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
4418 pointer to the stdio stream before calling scm_setbuf0, so the
4419 latter will be able to retrieve it. I'm surprised this didn't
4420 segfault earlier. (Thanks to Christopher Lee.)
4422 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4424 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
4427 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4429 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
4430 number of stack narrowing specifier pairs. The first specifier in
4431 a pair controls inner border, the second the outer border. A
4432 number means cut that number of frames, a procedure object means
4433 cut until that object is found in operator position in a frame.
4435 * root.c (cwdr): Bugfix.
4437 * read.c: Recording of positions disabled by default.
4439 * procs.c (scm_closure_p): New function.
4441 * posix.c (scm_tmpnam): New function.
4443 * load.c: Added #include "throw.h".
4444 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
4447 * load.c, load.h (scm_read_and_eval_x): New function.
4449 * eval.c: Renamed debug option "deval" to "debug".
4451 (scm_eval_x): `eval!' is no longer accessible from the scheme
4452 level. Motivation: We can't allow operations which introduce
4453 glocs into the scheme level. Guile's type system can't handle
4454 these as data. Use `eval' or `read-and-eval!' as replacement.
4456 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
4457 SCM_CONSP since this is a macro!; Set vframe.prev to
4458 scm_last_debug_frame instead of 0. In this way we can look
4459 "above" the virtual start stack frame if we wish.
4460 (scm_debug_hang): New function: Useful for debugging Guile in
4461 certain tricky situations. Will probably be removed later...
4463 * debug.h: Changed semantics of debug option "backtrace". This
4464 option now only indicates whether we want automatic backtrace at
4467 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4469 * ports.c: #include "filesys.h"
4470 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
4472 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
4473 Motivation: This is system specific code which is related to file
4474 I/O. It also may use select. Added code by Gary Houston to
4475 detect presence of character in stdio buffers.
4477 * libguile.h: #include "libguile/libpath.h"
4479 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4480 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4481 SCM_SITE_DIR; Install libpath.h among the other include files.
4483 * load.c, load.h (scm_sys_package_data_dir): New function.
4485 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4487 * stacks.h: Bugfix: Don't use tail-array length field as stack
4488 length field! This screwed GC.
4490 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4492 * _scm.h: Added #ifndef around definition of macros min and max.
4494 * __scm.h: Added hooks for threads to plugin to in ints protection
4495 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4496 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4497 the main code in these macros duplicated and spread over multiple
4498 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4499 SCM_THREAD_SWITCHING_CODE.
4501 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4503 * snarf.h: New file.
4504 * guile-snarf.sh: New file.
4505 * Makefile.in (inner_h_files): Added snarf.h
4506 (ancillary, install, uninstall, distclean): Added actions for
4508 (.c.x): Use guile-snarf.
4509 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4510 (gen_c_files): Note that these depend on guile-snarf.
4511 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4512 now in "snarf.h". Added #include "snarf.h" to get them.
4513 * libguile.h: Added #include "snarf.h".
4514 (Patches applied and tweaked by Jim Blandy.)
4516 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4518 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4519 standards suggest against providing prototypes for system
4520 functions. Thanks to Greg Troxel.
4522 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4524 * strports.c (scm_eval_0str): New function.
4525 #include "read.h", to get prototype for scm_read.
4526 * Makefile.in (strports.o): Update dependencies.
4527 * strports.h: New prototype.
4529 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4530 scheme name from "int?" to "integer?". It seems to do the job.
4531 * numbers.h: Rename prototype too.
4532 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4535 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4536 scm_num_eq_p): Rename these according to R4RS conventions: call
4537 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4538 to making libguile R4RS compliant without ice-9...
4540 * load.c (scm_sys_search_load_path): Search for files under all
4541 extensions listed in the %load-extensions variable. If FILENAME
4542 is absolute, return it unchanged, without searching the load path.
4543 (scm_loc_load_extensions): New variable, pointing to
4544 %load-extensions' value cell.
4545 (scm_init_load): Initialize it, and the value it points to.
4546 (scm_primitive_load_path): Improve error reporting.
4548 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4549 of new Scheme variable %load-hook.
4550 (scm_primitive_load): Apply %load-hook to filename.
4552 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4554 * configure.in: add tests for figuring out whether buffered data
4555 is available in a FILE structure, which is needed by char-ready.
4557 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4560 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4561 exceptions using misc_error instead of syserror. It seems a bit
4562 odd to throw an exception if a string can't be found in the
4563 environment, but it's consistent with open-file, stat etc.
4564 (simpos.h): remove sys_ from getenv.
4566 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4567 occurs, throw an error instead of returning errno. Return value
4569 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4571 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4573 * filesys.c (scm_stat2scm): derive file type and permissions from
4574 the stat mode and append them to the returned vector.
4575 There isn't much overhead in doing this and it avoids the need to
4576 work with S_IRUSR et al. in Scheme.
4577 Define symbols scm_sym_regular etc.
4578 (scm_init_filesys): don't intern S_IRUSR etc.
4580 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4581 and s_primitive_load_path.
4583 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4585 * error.h: don't declare error symbols. prototype for scm_misc_error.
4587 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4590 * error.c: use SCM_SYMBOL to set up error keys.
4591 scm_misc_error: new procedure.
4593 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4595 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4596 between `#!' and `!#' is ignored.
4597 (skip_scsh_block_comment): New function.
4599 * feature.c (scm_set_program_arguments): New argument, FIRST.
4600 * feature.h: Update prototype.
4601 * init.c (scm_boot_guile_1): Pass new argument to
4602 scm_set_program_arguments.
4604 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4606 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4607 (scm_boot_guile): Call scm_set_program_arguments here, later than
4608 the old initialization.
4610 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4611 initialization procedure.
4612 - Delete in, out, err arguments; there are other perfectly good
4613 ways to override these when desired.
4614 - Delete result argument; this function shouldn't ever return.
4615 - Rename init_func argument to main_func, for less confusion.
4616 - Delete boot_cmd argument; main_func is more general.
4617 -Add 'closure' argument, to help people pass data to main_func
4618 without resorting to global variables.
4619 - Abort if reentered; don't bother returning an error code.
4620 - Call scm_init_standard_ports to set up the default/current
4621 standard ports; no need to pass them to scm_start_stack.
4622 - Remove code to evaluate the boot_cmd, and start the repl; let
4623 the user do something like that in main_func if they want.
4624 - Remove code to package up a return value; main_func can do any
4626 - Call exit (0), instead of returning.
4627 (scm_start_stack): Don't initialize the I/O ports here; that's
4628 weird. Delete in, out, err arguments. Move guts to
4629 scm_init_standard_ports, scm_stdio_to_port.
4630 (scm_init_standard_ports): New function, to set up current and
4631 default standard ports.
4632 (scm_start_stack, scm_restart_stack): Make these static.
4633 * init.h (scm_boot_guile): Adjust declaration.
4634 (scm_start_stack, scm_restart_stack): Remove externally
4635 visible declarations for these.
4636 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4638 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4639 written out several times in scm_start_stack.
4640 * fports.h: New declaration for the above.
4642 * feature.c (scm_set_program_arguments): New function.
4643 * feature.h: New declaration for the above.
4645 * ports.c: Formatting tweak.
4647 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4649 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4650 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4651 for obtaining the address of a car or cdr field. Motivation:
4652 &SCM_CXR make assumptions about the internal structure of the
4655 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4656 Motivation: see SCM_CXRLOC.
4658 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4659 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4660 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4661 Motivation: Safer use. Some other macros are defined in terms of
4662 these operations. If these are defined using the SCM_SETCXR
4663 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4664 to inefficiency and an <e1> with side-effects could potentially
4665 break. Also, these particular operations are heavily utilized in
4666 the garbage collector. In unoptimized code there will be a
4669 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4670 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4671 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4672 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4673 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4674 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4675 vports.c: Cleaned up use of pairs: Don't make any special
4676 assumptions about the internal structure of selectors and
4677 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4678 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4679 (Among other things, this change makes it easier to build Guile
4680 with certain compilers which have problems with casted lvalues.)
4682 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4684 * stacks.c: Improve selection of relevant stack frames when making
4685 a stack object. Introduce one level of indirection in the stack
4686 object to make it possible to "narrow" to a certain region of the
4687 stack. This facilitates making use of more clever algorithms (not
4688 implemented) for selecting relevant frames and gives a cleaner
4689 design since selection of frames can be done independently of
4690 extraction of frames from the real stack.
4691 (scm_stack_id): Also take #t as argument which means look at
4694 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4695 Turn n_tail into an integer directly representing current number
4696 of frames in stack. Add field tail.
4698 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4700 * debug.c (scm_make_memoized): Made it available at scheme level.
4701 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4702 SCM_NIMP before applying heavier predicates in argument checking.
4703 (scm_local_eval): Also take memoized object as argument.
4705 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4706 aren't created with zero length, but should such a strange
4707 creature suddenly turn up...
4709 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4711 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4712 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4714 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4716 * variable.c (scm_make_variable): Make the name hint optional, as
4718 (anonymous_variable_sym): Renamed from variable_sym. All uses
4721 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4722 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4723 of scm_primitive_load_path was also changed to
4724 "primitive-load-path", from "%try-load-path". Callers changed.
4725 We'd like to respect the convention that a function named
4726 "try-mumble" should behave just like the function called "mumble",
4727 but return #f instead of signalling some error.
4728 * load.h: Rename prototypes.
4730 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4732 * print.c (make_print_state, grow_print_state), print.h: Modified
4733 the print state representation: Don't use a tail array for
4734 recording of circular references. Resizing of the print state
4735 structure invalidates the print state pointer. To avoid passing
4736 around an indirect print state reference to all printing
4737 functions, we instead let the print state reference a resizable
4740 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4742 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4743 Don't crash when passed an improper list terminated by a
4744 non-immediate value.
4746 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4748 Allocate data for structures on an eight-byte boundary, as
4749 required by the tagging system.
4750 * struct.c (alloc_struct): New function.
4751 (scm_make_struct, scm_make_vtable_vtable): Call it.
4752 * struct.h (scm_struct_n_extra_words): Bump to 3.
4753 (scm_struct_i_ptr): New "field".
4754 * gc.c (scm_gc_sweep): When we need to free the data, use the
4755 information stored by alloc_struct to find the beginning of the
4756 block allocated to the structure, so we can free it.
4758 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4760 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4763 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4764 (scm_debug_info): New member: id.
4766 * stacks.c: Stacks are now represented as structs; Stacks have an
4767 id given to them by `start-stack'.
4768 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4770 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4771 Changed stack representation.
4773 * debug.c (scm_procedure_name): Try procedure property `name' for
4774 compiled closures aswell.
4776 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4778 * eval.c: scm_i_name moved to gsubr.c
4779 (scm_m_define): Record names of all kinds of procedure
4780 objects. (Earlier, only closures were recorded.)
4782 * procprop.h: Added declaration of scm_i_name.
4784 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4785 (scm_make_gsubr): Record names of compiled closures.
4787 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4789 * debug.c, debug.h: Removed obsolete code.
4791 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4792 stacks.c: Renamed regs --> scm_contregs.
4794 * print.c (scm_free_print_state): Cleanup print state before
4795 returning it to pool. It is better to do it here than in
4796 scm_prin1 since scm_prin1 is called often.
4798 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4799 s_set_source_property_x): Check that first argument is a pair or a
4802 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4803 scm_i_line, scm_i_column and scm_i_breakpoint global.
4805 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4806 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4809 * debug.h: Added debug object smob declaration and macro
4812 * configure.in: Build with backtrace.o and stacks.o if debug
4815 * Makefile.in: Added entries for new files: backtrace.c,
4816 backtrace.h, stacks.c and stacks.h.
4818 * symbols.c (scm_sym2ovcell): Fixed documentation.
4820 * _scm.h (min, max): Added.
4822 * async.c: Moved `min' macro to _scm.h.
4824 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4825 SCM_BACKTRACE_INDENT.
4827 * eval.c: Added new debug options `maxdepth' and `indent'.
4829 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4831 * print.h: Added selector SCM_PRINT_STATE.
4833 * print.c: New functions: scm_make_print_state,
4834 scm_free_print_state.
4836 * print.h: Added declarations for scm_make_print_state,
4837 scm_free_print_state.
4839 * debug.c (scm_m_start_stack): New acro.
4841 * debug.h: Small cleanup.
4843 * init.c (scm_boot_guile_1): Moved scm_init_debug below

4871 More prototype-related changes from Marius Vollmer:
4872 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4873 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4874 * ports.h (ptobfuns): Added prototypes. This means some casting in
4876 * fports.c: Added casts for initializations, since the functions
4877 are defined to take FILE * as their stream argument, not SCM.
4878 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4879 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4880 to `char *str_data' to conform to prototype.
4882 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4884 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4886 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4888 * stime.c, stime.h: use SCM_P method.
4890 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4892 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4893 be given at least two arguments. Insist that lst's last element
4894 be a list, but don't make any requirements of its predecessors.
4896 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4898 * eval.c (scm_nconc2last): Revert last change; there seems to be
4899 other stuff going on here.
4901 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4903 * eval.c (scm_nconc2last): Make sure that each element of lst
4904 (which is a list of argument lists, except for the tail) is a
4905 proper list, i.e., finite and terminated by '().
4907 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4909 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4912 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4913 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4916 * vectors.c (scm_make_vector): Fill vectors with the undefined
4917 value, to help make Guile Scheme code more portable to other
4920 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4921 * symbols.h, tags.h: Doc fixes.
4923 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4925 * async.c (scm_take_signal): Doc fixes.
4927 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4929 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4930 want to subtract it from the modulus; we just want to leave it
4933 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4935 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4938 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4940 * throw.c (scm_catch_apply): Finished implementation of
4943 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4945 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4947 (scm_init_filesys): set "i/o-extensions" feature.
4950 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4952 * Makefile.in (root.o): Correct dependencies.
4954 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4956 * Makefile.in: Added dependency entry for root.o.
4958 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4959 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4961 * init.c (scm_start_stack): Set initial root continuation number
4964 * procs.c: New function: scm_thunk_p.
4966 * procs.h: Added declarations of scm_thunk_p.
4968 * root.c: Renamed `call-with-new-root' -->
4969 `call-with-dynamic-root'.
4970 (cwdr): Removed allocation of new root state. This should be done
4971 separately by use of scm_make_root.
4972 (scm_apply_with_dynamic_root): New function: Does what it
4973 sounds like. Needed when spawning threads.
4975 * root.h: Added member last_debug_frame to root state.
4976 Added #include "libguile/debug.h"
4978 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4979 arguments. The motivation is that code in root.c needs catch
4980 functionality, and we want to avoid code duplication.
4981 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4982 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4983 handlers that run without popping the stack into the dynwind
4986 * throw.h: Added prototypes for scm_catch_apply and
4989 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4991 * root.h (scm_root, scm_set_root): Decouple thread support details
4992 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4993 SCM_SET_THREAD_LOCAL_DATA.
4995 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4996 and tortoise scanning loop.
4998 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
5000 * Makefile.in: Rebuild dependencies.
5002 * libguile.h: #include "libguile/print.h" before "smob.h", since
5003 the latter uses the print_state structure.
5005 * throw.c (scm_ithrow): Use the correct variable when checking to
5006 see if a given element of scm_dynwinds is a valid catch.
5008 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
5009 structure, abort; don't just silently ignore the garbage.
5011 * _scm.h: #include "print.h" here, since it seems to be used just
5013 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
5014 strports.c, unif.h: Don't #include "print.h".
5016 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5018 * feature.h (scm_loc_features): Removed external declaration.
5019 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
5021 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5023 * feature.c (scm_init_feature): Added threads feature (needs to be
5024 initialized here, since features doesn't exist when
5025 scm_init_threads is called).
5027 * libguile.h: Added #include "libguile/../threads/threads.h".
5028 (This is a kludge to get thread support working. This should be
5031 * configure.in, acconfig.h: Added flags for thread support.
5033 * scmsigs.c: Define `signal' to be `pthread_signal' if using
5036 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
5037 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
5040 * _scm.h: Added conditional #include "threads.h"
5042 * __scm.h (SCM_ASYNC_TICK): Added call to macro
5043 SCM_THREADS_SWITCHING_CODE.
5045 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
5046 allocate the basic dynamic root object.
5047 (scm_boot_guile): Added call to scm_init_root.
5049 * root.c, root.h: Added root smob.
5050 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
5051 functions: Implements dynamic roots mostly according to spec in
5052 SCM manual. Main difference is that the second argument is a
5053 throw handler rather than an error "thunk".
5055 * root.h: Added declaration of scm_init_root.
5057 * root.c: Added #include "genio.h", #include "smob.h", #include
5058 "pairs.h", #include "throw.h", #include "dynwind.h", #include
5060 (scm_init_root): Added #include "root.x".
5062 * throw.c: Added #include "stackchk.h"
5063 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
5064 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
5065 can be used in scm_call_with_new_root; Added reenabling of stack
5066 checking when catching a throw.
5068 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
5070 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
5072 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
5073 element is not found, as per R4RS.
5075 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
5077 * list.c: Doc fixes throughout.
5079 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
5081 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
5082 declare the char * to be const. Avoids a warning in rgx.c.
5084 * ports.h: spelling fix.
5086 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
5089 * load.c (scm_sys_try_load_path): throw an error if file not found
5090 (like it says it in NEWS).
5092 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
5094 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
5095 PROPS slot to '(), not #f; it's an empty alist.
5097 * throw.h, throw.c: Use SCM_P instead of #if hair.
5099 Remove special support for uncaught throws; see throw.c for
5101 * throw.c (uncaught_throw): New function.
5102 (scm_ithrow): Call uncaught_throw if we don't find a throw
5103 target; don't mess with scm_bad_throw_vcell.
5104 (scm_bad_throw_vcell): Variable deleted.
5105 (scm_init_throw): Don't initialize it.
5107 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
5110 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
5112 * numbers.c (scm_istr2int): If the number is short (as most
5113 numbers are), just call scm_small_istr2int to deal with it.
5114 (scm_small_istr2int): New function, created by un-#ifdefing the
5115 non-bignum version of scm_istr2int and renaming it.
5117 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
5119 * load.c (scm_sys_try_load): don't check whether value returned
5120 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
5121 Change the Scheme name from %try-load to primitive-load.
5123 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
5124 Can avoid passing a message, allowing it to be derived in the
5125 error handler (e.g., if we want to throw to the key both from
5128 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
5130 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
5131 references now have a new appearance which is more compact and
5132 also gives a clue about what the target of the reference is.
5133 By setting parameters in the print state, more fancy printing can
5134 be achieved. This is used by the (not yet commited) backtrace
5137 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
5139 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
5142 * print.c: Added #include "struct.h". Removed function
5145 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
5146 scm_iprin1. Removed prototype for scm_prlist.
5148 * arbiters.c (prinarb),
5149 async.c (print_async),
5150 debug.c (prindebugobj, prinmemoized),
5151 eval.c (prinprom, prinmacro),
5152 filesys.c (scm_fd_print, scm_dir_print),
5154 mallocs.c (prinmalloc),
5155 numbers.c, numbers.h (scm_floprint, scm_bigprint),
5156 smob.h (scm_smobfuns),
5157 srcprop.c (prinsrcprops),
5159 unif.c, unif.h (scm_raprin1, rapr1),
5160 variable.c (prin_var): Changed argument `int writing' to
5161 `scm_print_state *pstate'.
5163 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
5164 that it will be called before scm_init_print.
5166 * print.c (scm_prin1): Print states are now allocated when calling
5167 scm_prin1 and then passed around to all printing functions as an
5168 argument. A cache `print_state_pool' enables reuse of print
5170 (scm_make_print_state): New function.
5171 (scm_iprin1): Adaption to print states.
5172 (scm_iprlist): An initial "hare and tortoise" scan brings down
5173 time complexity to O (depth * N). (Better time complexity will be
5174 achieved when the printing code is completely rewritten.)
5176 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
5178 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
5179 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
5180 it gets done whether or not the cache variable has a value.
5182 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5184 Distinguish #f and ().
5185 * __scm.h: #undef SICP.
5186 * pairs.h (SCM_EOL): Delete this definition, equating it with
5188 * tags.h (SCM_EOL): Give it a new definition here; I think I found
5189 the value it used to have. Doc fixes, too.
5191 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
5193 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
5194 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
5195 Lord's implementation of structs, allowing for tail arrays as
5196 described in the manual. Also fixed some bugs. (Both the interface
5197 and the implementation should be improved.)
5199 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
5201 * print.c, print.h: Closures now print like #<procedure foo (x)>.
5202 People who whish to see the source can do `(print-enable 'source)'.
5203 Removed #ifdef DEBUG_EXTENSIONS.
5205 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5207 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
5208 integer (assuming for now accepting an integer is a good thing).
5210 * error.c, fports.c: replace use of %S in lgh_error args with %s.
5211 %S will be used instead for write'ing arguments.
5213 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
5214 asserts. fix a few other asserts.
5215 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
5216 scm_uniform_vector_ref, scm_array_set_x,
5217 scm_dimensions_to_unform_array): change args in
5218 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
5219 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
5220 scm_substring_fill_x): likewise.
5221 gsubr.c (scm_gsubr_apply): likewise.
5222 eval.c (SCM_APPLY): likewise.
5224 * eval.c (4 places): replace scm_everr with lgh_error or
5227 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
5228 scm_memory_error): new procedures.
5229 scm_everr: deleted. can use scm_wta, dropping first two args.
5230 scm_error: convert NULL subr to SCM_BOOL_F.
5232 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
5235 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
5238 * error.c, error.h: new error keys: scm_arg_type_key,
5239 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
5241 scm_wta: reimplement using lgh_error instead of scm_everr.
5243 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
5245 * gdbint.c: scm_lread now has one more argument.
5247 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
5248 scm_port_\1; Added mutator scm_set_port_filename_x (used when
5249 loading source from non-file ports, which, e. g., happens when
5250 using the Emacs interface).
5252 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
5255 * read.c: Added code for recording of positions of source code
5256 expressions; New functions: recsexpr, scm_lreadrecparen;
5257 _scm_make_srcprops --> scm_make_srcprops
5258 (scm_flush_ws): Removed updating of positions counters. This work
5259 is already done by scm_gen_getc
5261 * read.h: Added prototype for scm_lreadrecparen
5263 * print.c: Added #include "alist.h"
5265 * eval.c: Added #include "hash.h"
5267 * eq.c: Added #include "ramap.h"
5269 * options.c: Documentation fixes.
5271 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
5272 (scm_init_srcprop): Adjusted size of initial source-whash. Name
5273 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
5274 --> scm_make_srcprops
5276 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
5277 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
5278 function calls in the definition of the whash access macros.
5280 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
5282 * init.c (scm_boot_guile): Add level of indirection to
5283 scm_boot_guile_1() to ensure that stack base pointer is properly
5284 initialized. There was no guarantee that variable i was the
5285 highest/lowest variable on stack (i.e. the call frame of
5286 scm_boot_guile was not completely protected from gc).
5288 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
5290 * ports.h (scm_port_table): put back file_name, it will be used to
5291 support debugging. Undo related changes in fports.c, ioext.c,
5294 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5296 * ports.h (scm_port_table): remove file_name member for now, it seems
5298 * fports.c (scm_open_file): don't set file_name in PTAB.
5299 (prinfport): don't use file_name in PTAB.
5300 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
5301 * ports.c (scm_add_to_port_table): don't intialize file_name.
5302 (scm_port_file_name): remove for now.
5303 * gc.c (scm_gc_mark): don't mark PTAB file_name.
5305 * fports.h (scm_mkfile): prototype deleted.
5306 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
5308 * debug.c, unif.c: use scm_out_of_range instead of
5309 wta for range errors (ASSERT still needs work).
5311 * error.c, error.h (scm_out_of_range): new procedure.
5313 * error.c, error.h (scm_out_of_range_key): new key.
5315 * posix.c (scm_sync): #else was missing.
5317 * error.c, error.h: append _key to names scm_num_overflow and
5320 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
5321 of consing an empty list.
5322 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
5323 of macros, saves code and string space.
5324 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
5325 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
5326 lower case. Rename scm_syserror_m to scm_syserror_msg.
5327 error.h: prototypes for new procedures.
5329 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
5331 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
5333 * error.c, error.h: setup scm_num_overflow key.
5335 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
5336 Remove definition of SCM_OVSCM_FLOW.
5338 * fports.c (scm_open_file): use SCM_SYSERROR_M.
5340 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
5341 explicit message and args.
5343 * error.c, error.h, __scm.h: change system_error_sym to
5346 * error.c (system_error_sym): remove leading %% from the Scheme name
5349 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
5351 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5353 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
5354 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
5355 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
5356 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
5357 renamed. (These were introduced by unsupervised name
5360 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5362 * print.c: Added code for detection of circular references during
5363 printing. (init_ref_stack, grow_ref_stack): New functions. Added
5364 a hook for printing of closures (accessible via print options).
5365 This leads to a split of calls to scm_iprin1 into two classes:
5366 elementary print operations (e. g. the code which prints a smob)
5367 still use scm_iprin1 while top level calls (like scm_display) use
5368 scm_prin1. scm_prin1 begins by clearing the data structure used
5369 to record reference information.
5371 * print.h: Added declarations of scm_prin1 and scm_prlist.
5373 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
5375 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
5377 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
5379 * error.c (err_head): scm_iprin1 --> scm_prin1
5381 * debug.c: Adjusted header comment.
5385 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
5387 * strerror.c: Doc fix.
5389 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5391 * gdbint.c (gdb_read): Now possible to run during GC.
5392 (unmark_port, remark_port): New functions.
5394 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
5396 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
5397 of allocating a new string object. Also, increase size by
5398 the factor 2 instead of 1.5.
5400 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
5402 * __scm.h (SCM_P): Corrected to run under traditional C.
5404 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
5407 * async.c: Calls to scm_sysintern corrected.
5409 * async.h (scm_async_clock): Redundant declaration removed.
5411 * continuations.c (scm_dynthrow): Redundant declaration removed.
5413 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
5414 Definition typos corrected.
5416 * debug.h: Missing declarations of functions in debug.c added
5419 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
5420 Missing declarations to functions in eval.c added.
5422 * filesys.c: Possibly uninitialized variable rv.
5424 * gc.h (scm_object_addr, scm_unhash_name): Missing
5425 declarations of functions defined in gc.c added.
5427 * genio.c: Possible typos str_data -> wstr_data. ???
5429 * genio.c: Possibly unintended shadowing of local variable
5430 `int c' (gotos out of scope of inner `c'). ???
5432 * init.c: Uninitialized `SCM last' may be used.
5434 * ioext.h: (scm_sys_isatty_p): Typo.
5436 * list.h (scm_list_head): Missing prototype for function in
5439 * numbers.c (scm_two_doubles): Changed from extern to static
5440 (is used only within numbers.c).
5442 * numbers.h: Repeated declarations removed.
5444 * ports.h (scm_close_all_ports_except): Declaration for the
5445 function defined in ports.c added.
5447 * posix.h: Missing declarations added.
5449 * procs.h (scm_make_subr_opt): Missing declaration added.
5451 * socket.h (scm_sys_gethost): Missing declaration added.
5453 * socket.h: Redundant declarations removed (they are in fdsocket.h).
5455 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
5456 Missing declarations added.
5458 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
5460 * struct.c: Uninitialized variable `SCM answer' may be used.
5462 * unif.c (l2ra): Declaration prototype.
5464 * unif.c (scm_array_equal_p): Dummy definition removed (it is
5465 defined in ramap.c).
5467 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
5468 Redundant declarations removed (they are in ramap.h).
5470 * variable.h (scm_make_udvariable,
5471 scm_make_undefined_variable): Declaration corrected to
5472 correspond variable.c.
5474 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
5475 Missing declarations added.
5477 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5479 * Makefile.in (distclean): Don't forget to delete fd.h.
5481 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5483 * fd.h.in, tags.h: Trivial cleanups.
5485 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5486 marksweep.h just declared functions from gc.c.
5487 * gc.h, libguile.h: Don't #include "marksweep.h".
5488 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5489 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5490 dependencies updated.
5492 * libguile.h: Don't #include "files.h"; it's been deleted.
5494 * files.c (scm_sys_delete_file): Moved to filesys.c.
5495 File is now empty; deleted.
5497 * filesys.c: scm_sys_delete_file is now here. Remove
5498 #if's; they seem to rely on remnants of an old portability
5499 regimen. If the problems come up again, solve them properly,
5500 using autoconf. Specifically: Don't test M_SYSV, and #define
5501 remove to be unlink if it's #defined; don't use remove just
5502 because HAVE_STDC_HEADERS is #defined.
5503 * filesys.h: Add declarations for scm_sys_delete_file.
5504 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5505 files.o, files.h, files.c, and files.x.
5506 * init.c: Don't #include "files.h", and don't call scm_init_files.
5508 Use SCM_P instead of PROTO; the latter intrudes on the user's
5510 * params.h: Deleted; definition of SCM_P moved to...
5511 * __scm.h: ... here, where it replaces PROTO macro.
5512 * libguile.h, smob.h: Don't #include "params.h".
5513 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5514 smob.h: Fix prototypes accordingly.
5515 * Makefile.in: Update dependencies.
5516 (inner_h_files): Remove params.h.
5518 * gc.c: #include "gc.h"; every module should include its header,
5519 to let the compiler cross-check the declarations against the
5522 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5523 simpos.h: #include "libguile/__scm.h".
5525 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5527 * init.c: Don't forget to #include smob.h and init.h.
5528 * Makefile.in: Dependencies updated.
5530 * smob.h: Use PROTO instead of #if __STDC__.
5532 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5534 * __scm.h: Doc fixes.
5536 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5537 <angles>; this allows `make depends' to work properly.
5539 * libguile.h: #include smob.h and pairs.h before the others; they
5540 define typedefs used by other headers.
5542 C files should #include only the header files they need, not
5543 libguile.h (which #includes all the header files); the pointless
5544 recompilation was wasting my time.
5545 * Makefile.in (all .o dependency lists): Regenerated.
5546 * libguile.h: Don't try to get a definition for size_t here...
5547 * __scm.h: Do it here.
5548 * _scm.h: Since this is the internal libguile header, put things
5549 here that all (or a majority) of the libguile files will want.
5550 Don't #include <libguile.h> here; that generates dependencies on
5551 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5552 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5553 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5650 * weaks.c: Get "weaks.h".
5652 * stackchk.h: #include "libguile/debug.h",
5654 * print.h, read.h: #include "options.h", since everyone who uses
5655 either of these files will need that.
5657 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5658 anyone who uses this file will need them to define the smob
5659 printing functions. Also, get markers.h, since people will need
5660 to #define the mark functions.
5662 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5663 * ports.h: ... to here.
5665 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5666 don't rely on archaic C default type rules.
5668 * fports.h: #include "libguile/ports.h", since you need that in
5669 order to parse this.
5671 * genio.h: #include "libguile/print.h", because you need that to
5672 parse this; don't bother #including "ports.h", since print.h gets
5675 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5677 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5678 this; it's now a reference to an element of *scm_root.
5680 * debug.h: Don't #include "options.h"; the compiler won't be able
5681 to find that once the headers are installed; instead, #include
5682 "libguile/options.h".
5683 * gc.h: Same, with marksweep.h.
5684 * mbstrings.h: Same, with symbols.h.
5685 * scmhob.h: Same, with _scm.h.
5686 * smob.h: Same, with params.h.
5688 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5689 C files; there's no need for this, and it forces recompilations
5692 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5694 * error.c (scm_error): declare scm_error_callback.
5696 * error.h: prototype for scm_error_callback.
5698 * __scm.h: define lgh_error.
5699 (SCM_SYSERROR): redefine using lgh_error.
5701 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5703 * error.c (scm_error): new procedure.
5705 * error.h: prototype for scm_error.
5707 * Makefile.in (install): install scmconfig.h from the current
5708 directory, not $(srcdir).
5710 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5712 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5713 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5714 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

5720 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5721 vports.h, weaks.h: #include "libguile/__scm.h", not
5722 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5723 dependencies are within libguile properly.
5725 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5727 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5728 when scmconfig.h doesn't exist.
5730 * load.c (scm_sys_try_load): Correct spelling.
5732 * feature.c (scm_loc_features): Make this static.
5734 * Makefile.in (libpath.h): Omit trailing slash from path. We
5735 shouldn't require it of users, so why put it here?
5737 Move code to initialize and search %load-path from ice-9 to C
5738 code, so we can use the load-path to find the ice-9 boot code;
5739 this makes it easier to run Guile without installing it. See
5740 corresponding changes in guile/Makefile.in.
5741 * feature.c: Move stuff concerned with the load path to load.c.
5742 (scm_compiled_library_path): Deleted.
5743 Don't #include libpath.h here.
5744 * feature.h: Don't mention scm_compiled_library_path.
5745 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5746 <sys/stat.h>, and <unistd.h> (if present).
5747 (R_OK): #define if the system hasn't deigned to.
5748 (scm_loc_load_path): New variable.
5749 (scm_init_load_path, scm_sys_search_load_path,
5750 scm_sys_try_load_path): New functions.
5751 (scm_init_load): Initialize scm_loc_load_path to point to the
5752 value cell of the Scheme %load-path variable.
5753 * load.h: Add declarations for scm_sys_search_load_path,
5754 scm_sys_try_load_path.
5755 * init.c: Call scm_init_load_path.
5756 * Makefile.in (feature.o, load.o): Dependencies updated.
5758 * load.c, load.h: Rewrite using PROTO macro.
5760 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5762 * gc.c (scm_cellp): New function: C predicate to determine if an
5763 SCM value can be regarded as a pointer to a cell on the heap.
5765 * gc.h: Added declaration of scm_cellp.
5767 * gdb_interface.h: New file: The GDB interface header from the GDB
5770 * gdbint.c: New file: GDB interface.
5772 * gdbint.h: New file: GDB interface.
5774 * libguile.h: Added #include <libguile/gdbint.h>.
5776 * init.c (scm_boot_guile): Added scm_init_gdbint.
5778 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5779 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5780 found if object files and source are kept separate).
5782 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5784 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5786 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5788 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5789 TK_SRC_DIR; they're not relevant any more.
5791 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5792 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5794 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5796 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5797 search path, so we can find the <libguile/MUMBLE.h> headers.
5799 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5801 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5802 implicit in the .c.o rule.
5803 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5806 Put the library path in a header file, instead of passing it on
5807 the command line in every compilation.
5808 * Makefile.in (libpath.h): New target.
5809 (feature.o): Depend on libpath.h.
5810 (clean): Delete libpath.h.
5811 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5812 * feature.c: ... #include "libpath.h" here.
5813 * .cvsignore: Ignore libpath.h.
5815 Don't install the unwashed masses of Guile header files in the
5816 main #include path; put most of them in a subdirectory called
5817 'libguile'. This avoids naming conflicts between Guile header
5818 files and system header files (of which there were a few).
5819 * Makefile.in (pkgincludedir): Deleted.
5820 (innerincludedir): New variable; this and $(includedir) are enough.
5821 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5822 (installed_h_files): Divide this up. Now this variable lists
5823 those header files which should go into $(includedir) (i.e. appear
5824 directly in the #include path), and ...
5825 (inner_h_files): ... this new variable says which files appear in
5826 a subdirectory, and are referred to as <libguile/mumble.h>.
5827 (h_files): List them both.
5828 (install): Create innerincludedir, not pkgincludedir. Put
5829 the installed_h_files and inner_h_files in their proper places.
5830 (uninstall): Corresponding changes.
5831 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5832 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5833 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5834 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5835 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5836 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5837 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5838 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5839 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5840 vports.h, weaks.h: Find __scm.h in its new location.
5841 * __scm.h: Find scmconfig.h and tags.h in their new locations
5842 (they're both "inner" files).
5844 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5846 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5848 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5850 * posix.c: Doc fixes.
5852 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5854 * socket.c: Don't include a prototype for inet_aton; just use a
5855 K&R style declaration, to avoid warnings but minimize the chance
5856 of conflicts with the system.
5858 On NextStep, <utime.h> doesn't define struct utime, unless we
5859 #define _POSIX_SOURCE before #including it.
5860 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5861 * acconfig.h: New comment text for above CPP symbol.
5862 * configure.in: Call it.
5863 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5865 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5867 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5868 testing for __EMX__.
5870 * posix.c: #include <libc.h>, if it exists.
5872 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5873 don't even know if the latter exists.
5875 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5876 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5877 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5879 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5881 (scm_init_posix): Use them when initializing the Scheme constants
5884 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5886 * Makefile.in (libdir, includedir, bindir): Use the
5887 autoconf-supplied values, instead of deriving them ourselves.
5888 (pkgincludedir, datadir, pkgdatadir): New variables.
5889 (install, uninstall): Put the header files in a special
5890 subdirectory, not in the main search path.
5892 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5893 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5895 * Makefile.in (IMPLPATH): Deleted; never used.
5897 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5898 on the Tcl/Tk source any more.
5899 (INCLUDE_CFLAGS): Remove references to the above.
5901 * Makefile.in (version.o): Corrected dependencies.
5903 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5905 * libguile.h: #include "version.h"
5907 * init.c (scm_boot_guile): Call scm_init_version.
5908 * gscm.c (gscm_run_scm): Call scm_init_version.
5910 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5911 GUILE_VERSION): AC_DEFINE these.
5912 (acconfig.h): #undef the above symbols.
5914 * Makefile.in (libobjs): Add version.o.
5915 (installed_h_files): Add version.h.
5916 (c_files): Add version.c.
5917 (gen_c_files): Add version.x.
5918 (version.o): New rule.
5919 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5920 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
5921 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
5922 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
5923 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
5924 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
5925 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
5926 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
5927 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
5928 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5929 weaks.o): Add version.h to dependency lists.
5930 (markers.o): Remove duplicate rule.
5932 * version.h: New file.
5934 * version.c: New file.
5936 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5938 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5939 array; use it appropriately. Since GCC is quite happy to
5940 subscript functions, it never warned us about this; we should use
5941 -Wpointer-arith in the future. I guess we never tested
5944 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5946 * socket.c: Doc and copyright fixes.
5948 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5950 * debug.c: Fixed and improved gdb support.
5952 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5954 * socket.c: Added declaration of inet_aton to avoid compiler
5955 warning. (Hope this solution is correct.)
5957 * stime.c: Added declaration of ftime. (This is missing in
5960 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5962 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5964 * Makefile.in (c_files): add strerror.c.
5966 * strerror.c: new file from Emacs' sysdep.c.
5967 maybe configure should also check for sys_errlist.
5969 * configure.in (AC_REPLACE_FUNCS): add strerror.
5971 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5973 * debug.c (scm_init_debug): Added initialization for
5974 scm_evaluator_traps.
5976 * debug.h, debug.c: Various name changes.
5977 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5978 "debug-options-interface". See commentary in options.c.
5980 * options.h, options.c: Options now have documentation strings.
5981 Also added a long explanatory commentary.
5983 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5986 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5987 last_debug_info_frame is now updated in all cases.
5989 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5992 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5994 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5995 Added option STACK_CHECKING.
5997 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5999 * Makefile.in: Added {debug,options,srcprop}.{h,c}
6001 * __scm.h: Removed symbols for debugging support.
6003 * acconfig.h: Added symbols for debugging support.
6005 * configure.in: Added user option for debugging support.
6006 --enable-debug will include the debugging code into libguile.a.
6008 * continuations.c (scm_make_cont): Enlarged the #if 0 around
6009 scm_relocate_chunk_to_heap.
6011 * debug.c: New file: low-level debugging support. It also
6012 includes support for debugging with gdb. (The extensions to gdb
6013 are written by Per Bothner at Cygnus.)
6015 * debug.h: New file: low-level debugging support.
6017 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
6018 argument pairs. Extensive modifications to the debugging
6019 evaluator. Added "SECTION:" commentaries to clarify what happens
6020 when, during double compilation. Renamed EVALIMP --> EVALIM.
6021 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
6022 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
6023 the beginning of the file. New procedure: scm_unmemocopy.
6024 Added some global state variables needed by the debugging
6025 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
6026 check_entry, check_apply, check_exit, debug_options and
6027 evaluator_traps. New acro: undefine.
6029 * eval.h: Renamed EVAL --> XEVAL.
6031 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
6032 --> scm_make_weak_key_hash_table.
6034 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
6035 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
6037 * libguile.h: Conditionally include debug.h
6039 * objprop.c (scm_object_properties, scm_set_object_properties_x):
6040 scm_object_properties shouldn't return handle. `handle' now gets
6041 initialized in scm_set_object_properties_x. scm_object_properties
6042 doesn't any longer create an entry in scm_object_whash.
6044 * options.c: New file: handling of run time options.
6046 * options.h: New file: handling of run time options.
6048 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
6050 * print.c: New procedure: scm_print_options
6052 * print.h: Defines for print options.
6054 * read.c: New procedure: scm_read_options
6056 * read.h: Defines for reader options.
6058 * root.h: Added scm_source_whash among scm_sys_protects.
6060 * srcprop.c: New file: source properties.
6062 * srcprop.h: New file: source properties.
6064 * throw.c (jbsmob): Jump buffers are now correctly allocated.
6065 (Bug found by A. Green.)
6067 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
6069 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
6071 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
6073 * libguile.h: #include "objprop.h"; I guess this was forgotten.
6075 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
6076 and should be called by the final client.
6078 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
6080 * gc.h: Use the PROTO macro when declaring functions.
6081 * gc.c: Use the PROTO macro when declaring static functions.
6082 Remove the CPP hair around function definitions.
6084 * gc.c (scm_init_storage): Initialize scm_asyncs.
6086 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
6087 preprocessor symbol; "__scm.h" is where it might get #defined.
6088 * __scm.h: Similar: #include <scmconfig.h> before testing
6091 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
6093 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
6095 * init.c (scm_boot_guile): Add init_func argument; call
6096 (*init_func) instead of calling scm_appinit; it's ucky to
6097 hard-code names for the user's procedures.
6098 * init.h (scm_boot_guile): Adjust declaration.
6100 * __scm.h (PROTO): New macro, for declaring functions with
6103 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
6104 eliminate all the __STDC__ conditionals.
6105 (scm_boot_guile): Add declaration.
6106 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
6107 Remove __STDC__ conditionals around function definitions; the
6108 declarations in init.h will provide the same information, more
6111 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
6112 complain about it in the error message; the error message is
6113 adequate without that note, and there's nothing the user can do
6116 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
6118 * Makefile.in (ancillary): Drop def.sed.
6120 * posix.c (scm_init_posix): Use numeric values, rather than
6121 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
6122 F_OK. The symbols aren't available on some systems, and I'm
6123 pretty sure their values are fixed by common widespread practice.
6124 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
6126 More functions unavailable on some systems.
6127 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
6128 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
6130 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
6131 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
6132 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
6133 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
6134 stub that signals an error as the #else.
6136 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
6138 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
6140 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
6142 * unif.c: include ramap.h.
6144 * read.c (endif): case_insensative_p renamed case_insensitive_p.
6146 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
6148 * ports.c: include sys/ioctl.h.
6150 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
6152 * configure.in: check for sys/ioctl.h.
6154 * ports.c: include <malloc.h> not "malloc.h".
6156 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6158 * fports.c: remove ttyname and tmpnam declarations.
6160 * posix.c: fewer ttyname declarations.
6162 * fports.c: include <string.h> not "string.h".
6164 * init.c, ioext.c: include string.h and unistd.h.
6166 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6168 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
6169 genio.c, simpos.c, vports.c: include string.h.
6171 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
6173 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
6175 (scm_addr_buffer_size): change type from scm_sizet to int.
6176 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
6177 from scm_sizet to int.
6179 * error.c: include unistd.h.
6181 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
6184 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
6186 * __scm.hd, def.sed: deleted.
6188 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
6190 Changes for NeXT, suggested by Robert Brown.
6191 * configure.in: Call AC_TYPE_MODE_T.
6192 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
6193 NeXT. Put header file list in alphabetical order.
6194 * configure, scmconfig.h.in: Regenerated.
6195 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
6197 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
6200 * acconfig.h: New file, providing documentation for the CPP
6201 symbols defined in configure.in
6202 * acconfig-1.5.h: Removed; superceded by the above.
6204 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
6206 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
6208 * fports.c (scm_open_file): don't return #f, throw error.
6210 * ioext.c (fileno): renamed from %fileno.
6211 (soft-fileno): deleted.
6213 * ports.c (scm_port_revealed): don't need to check for -1 from
6215 (scm_set_port_revealed_x): return unspecified, not #f.
6217 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
6219 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
6221 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
6223 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
6225 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
6227 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
6228 This is necessary on Ultrix, and doesn't hurt portability.
6230 * Makefile.in (dist-dir): New target, implementing a new dist system.
6231 (installed_h_files): Put in alphabetical order.
6232 Remove duplicate entries for markers.h and unif.h.
6233 (c_files): Remove duplicate entries for markers.c.
6234 (ancillary): Renamed from anillery; all uses changed. Remove
6235 PLUGIN; it's a directory, and needs special treatment in dist-dir.
6236 Remove all the ../doc/* files; doc/Makefile.in handles that.
6238 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
6240 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
6241 every if must have an else, or else the whole command has a
6242 non-zero exit code whenever the if's condition is false.
6244 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
6246 * posix.c: include string.h.
6248 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
6250 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
6253 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:

6501 initialization to fix a race condition.
6503 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
