1 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
3 * init.c, readline.c: OK, I won't have these readline.x bug
4 reports anymore. We've had them since April. The current reason
5 is a completely unintelligible failure of totoro.red-bean.com to
6 do the test for rl_getc_function in libreadline correctly. This
7 kludge overrides the test if we're on totoro so that the snapshot
8 generation process can work.
10 * readline.c: Define a strdup replacement if not existent on system.
12 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
14 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
15 This change makes scm_make_vector R5RS compatible. We cannot keep
16 the third argument since people want to be able to deduce the form
17 of the C function call only by looking at R5RS. (At the same time
18 we have removed some unnecessary complexity!)
20 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
21 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
22 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
23 argument in call to scm_make_vector.
25 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
27 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
28 This macro is useful in applications.
30 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
32 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
33 (scm_parse_path, scm_search_path): New Scheme level procedures.
35 * load.h (scm_internal_parse_path, scm_parse_path,
36 scm_search_path): Declared.
38 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
40 * filesys.c (dirname, basename): New procedures.
42 * init.c (scm_boot_guile_1): Removed condition around
45 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
46 new data type (guards) for representation of C level guards and
47 data on the wind chain.
48 (scm_internal_dynamic_wind): New function.
50 * dynwind.h: Declare scm_internal_dynamic_wind.
52 * root.h (scm_root_state): Added scm_cur_loadp.
54 * root.c (mark_root): Added comment about cur_loadp.
56 * load.c: #include "dynwind.h";
57 (scm_primitive_load): Use scm_inner_dynamic_wind to update
60 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
62 * ports.c (current-load-port): New procedure.
64 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
66 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
69 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
70 to Julian Satchell and Roland Kaufmann.)
72 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
73 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
75 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
77 * debug.h, debug.c (scm_start_stack): New function. Implements
78 the guts of old scm_m_start_stack.
80 * debug.c (scm_m_start_stack): Use scm_start_stack.
82 * init.c (scm_start_stack, scm_restart_stack): Renamed to
83 start_stack and restart_stack. (These have static scope.)
85 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
87 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
88 readline functions to come in release 2.3. (Thanks to Chet
90 (handle_errors): Use the above functions.
92 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
94 * readline.c: Improvements for readline support: Handle errors
95 better; Implement before-read-hook.
97 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
99 * init.c (scm_boot_guile_1), readline.c: Test for
100 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
101 assure that we have version >= 2.1.)
103 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
105 * readline.c (scm_add_history): Bugfix: Do strdup before giving
106 away the string to add_history.
107 (completion_function): Do completion for readline. (Thanks to
109 (scm_filename_completion_function): New procedure: Filename
111 (current_input_getc): New function. Use this one instead of
112 standard getc from readline.
114 * throw.c, throw.h (scm_handle_by_throw): New function: This
115 handler throws errors to next handler on the dynwind chain.
117 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
119 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
122 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
124 * procprop.c (scm_i_procedure_arity): New function. Returns arity
126 (scm_procedure_properties): Modified to return arity together with
128 (scm_procedure_property): Added the read-only property `arity'.
129 (scm_set_procedure_property_x): It is an error to set the `arity'
132 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
133 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
135 * procprop.h (scm_sym_arity): New symbol.
137 * objects.c (scm_set_object_procedure_x): New procedure: Use this
138 to set the dispatch procedure of an operator or entity object.
140 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
141 Made procedure slots read-only.
143 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
144 scm_tcs_cons_gloc case in zero args switch; Fixed args
145 construction for operators in scm_tcs_cons_gloc case in two args
148 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
150 * fluids.c: Removed use of assert.h (in order to avoid
153 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
155 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
157 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
158 change makes the evaluator safer at the cost of evaluation speed.
159 It handles the case when the user has added a non-immediate
160 improper end of the application form, e.g., `(+ 0 . x)'.
161 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
162 minimize the extra cost as much as possible. The new code is
163 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
164 problem with structs planted directly in the code (e.g. by a
165 macro). This no longer causes segmentation fault. (Thanks to
168 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
169 arg `proc' in order to be able to throw errors; New argument
172 * Removed extra #include "debug.h"
174 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
176 * scmsigs.c: Declare usleep as returning void on some systems.
177 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
180 * coop.c (usleep): Return void on some systems.
182 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
184 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
186 * coop.c: Changed return type of usleep to int.
188 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
189 isn't found in the OS.
191 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
192 isn't enabled. (Thought that I had made this change ages ago...)
194 * iselect.c: Declare bzero if not defined by OS.
196 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
198 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
199 condition. (Thanks to John Tobey.)
201 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
202 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
205 * __scm.h: Start the long-term project of moving to POSIX threads.
206 Phase 1: Classification of all critical sections.
207 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
208 for A sections. (See comments in __scm.h for details.)
210 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
211 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
213 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
215 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
216 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
217 (libpath.h, versiondat.h): Replaced dependency on Makefile with
218 dependencies on $(srcdir)/Makefile.in
219 $(top_builddir)/config.status in order to avoid circularity.
221 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
222 from argc if argc was 0 initially.
224 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
225 in generation of libpath.h.
227 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
229 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
230 libguile from 2 to 3.
232 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
234 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
236 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
238 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
239 scm_set_port_column_x, scm_port_filename,
240 scm_set_port_filename_x): Removed optional arguments. Added
241 proper argument checking.
243 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
244 stack size in machine words.
246 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
247 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
248 to Ole Myren Röhne.)
250 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
252 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
253 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
255 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
258 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
259 procedure apply: Copy argument lists before pushing them unto the
260 environment so that the environment won't get mutated due to
261 manipulation of procedure arguments. This should perhaps be
262 regarded as a temporary solution until someone finds a more
263 efficient one. (Thanks to Maciej Stachowiak.)
265 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
267 * script.c (scm_compile_shell_switches): Use "guile" as default
268 zero arg if argc is NULL.
270 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
272 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
273 is zero. (Thanks to Dirk Herrmann.)
275 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
277 * ports.c (scm_add_to_port_table): First line is now line 0
278 (was 1). (Interface changed according to suggestion by Per
281 * backtrace.c (display_header): Add 1 to line and column numbers
282 when presenting them to the user.
284 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
285 from debug.c --> eval.c
287 * eval.h, eval.c (scm_eval_options_interface): New options
289 (SCM_EVAL_STACK): New option: Size of newly created stacks,
290 i.e. stacks for new threads.
292 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
294 * eval.c (unsafe_setjmp): Removed with #if 0.
296 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
299 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
300 to avoid compiler warnings.
302 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
304 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
306 * throw.c (handler_message): Print message on current error port
307 instead of default error port. (Thanks to Maciej Stachowiak.)
309 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
311 * ports.c (scm_add_to_port_table): allocate in units of
312 struct scm_port_table *, not struct scm_port_table.
313 * posix.c (scm_close_pipe): remove the port from the port table
315 Thanks to Rob Engle for both fixes.
317 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
319 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
320 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
322 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
324 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
326 * backtrace.c (display_error_body, display_backtrace_body),
327 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
328 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
329 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
330 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
333 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
334 don't receive the jmpbuf arg anylonger.
335 (scm_catch): Don't accept a #f tag.
336 (scm_throw): Check that key is a symbol.
337 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
339 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
341 * async.c (async_pending): Removed declaration.
343 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
345 * dynwind.c (scm_wind_chain): New debug function.
347 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
348 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
349 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
350 extra layer of functions around the body and handler of a thread.
351 This extra layer makes sure that the handler is called in the
352 dynamic context of the surround (= empty dynwind list), but under
353 the *dynamic root* of the body. We can not use the dynamic root
354 of the surround since that root belongs to another thread => stack
355 is not handled correctly. It may seem ugly to use this extra
356 layer, but the extra cost in terms of execution time is really
357 negligible compared to the total amount of time required to create
358 a thread, and it would reduce maintainability to duplicate the
359 crucial and complicated steps performed by cwdr.
361 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
362 (SCM_ALLOW_INTS): Added thread switching code before interrupts
363 get re-enabled. The important effect of this is that interrupts
364 are blocked during thread switching so that thread data structures
365 don't risk getting messed up by an unfortunate signal.
366 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
367 seems to do more aggressive optimization which actually move
368 instructions around in these macros in a fatal way. Therefore:
369 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
370 just superstitious...)
371 (SCM_TICK): Maybe do a context switch and take care of asyncs.
372 This macro should be used instead of SCM_ASYNC_TICK since the
373 latter doesn't do context switches any more.
375 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
376 instead of SCM_ASYNC_TICK.
378 * coop.c, iselect.c: Since thread switches are now performed with
379 interrupts masked, we can't use the old mechanism of delivering
380 signals immediately when they arrive. Signals must instead be
381 delivered when the asyncs run *after* the end of the critical
382 section in scm_internal_select. But this also means after context
383 switch so that the signal will be delivered to a different thread.
384 To avoid this, I have changed the protocol of
385 coop_wait_for_runnable_thread and friends so that they are allowed
386 to return the original thread. So, if a signal arrives during
387 scm_internal_select, we won't any longer be forced do a context
388 switch, but can remain in the same thread and deliver the signal
391 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
392 scm_asyncs_pending and made it global.
394 * iselect.c: Small fixes.
396 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
397 coop_condition_variable_init, coop_condition_variable_wait,
398 coop_condition_variable_signal): Changed return type from `void'
399 to `int'. This is to adhere closer to the pthreads interface.
400 This, in turn, is part of an attempt to provide C versions of the
401 mutex and condition variable primitives which can be part of a
402 frontend to COOP or pthreads.
404 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
405 coop_condition_variable_destroy): New functions.
407 * coop-threads.c (scm_wait_condition_variable): Use
408 coop_condition_variable_wait_mutex.
410 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
411 Definitions moved to coop-defs.h.
413 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
414 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
415 scm_cond_destroy): New C interface to mutecis and cond vars.
417 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
419 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
421 * iselect.c: Now several threads can wait on the same file
422 descriptor. The behaviour is compatible with OS select: All
423 threads waiting for the fd return with the same status.
425 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
427 * coop-threads.c, threads.h (scm_spawn_thread): New function.
428 Can spawn a thread from application C code.
430 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
432 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
433 gh_doubles2scm): New functions.
435 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
437 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
438 commented-out version of gh_eval_str()
440 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
442 * socket.c (scm_bind): free soka after use.
444 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
446 * stime.c (tzvar): new variable.
447 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
448 avoid memory leaks when allocating.
450 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
452 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
455 * gc.c, tags.h: Doc fixes.
457 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
459 * eval.c (macro-eval!): Removed. This function was a design bug.
460 It allowed memoized code to leak out to the scheme level. Most
461 things that you could do with `macro-eval!' can be done with
464 1997-12-20 Tim Pierce <twp@skepsis.com>
466 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
467 scm_fgets now depends on ftell(3) to know how many bytes were
470 1997-12-15 Tim Pierce <twp@skepsis.com>
472 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
473 dealing with strings.
475 1997-12-13 Tim Pierce <twp@skepsis.com>
477 Make %read-line more suitable for implementing read-line efficiently.
478 * ioext.c (scm_read_line): Strip the terminating newline from a
479 string, and return a cons of the string and its terminator.
481 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
482 of the string that is read is stored in this memory location.
483 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
484 * genio.c, genio.h (scm_do_read_line): Update caller.
485 * ports.h (scm_ptobfuns): Update typedef.
486 * fports.c (scm_fptob, scm_pipob): Update struct.
488 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
490 * filesys.c (set_element): Return file descriptor.
491 (fill_select_type): Return the highest file descriptor.
492 (scm_select): Tell select about the highest file descriptor. On
493 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
494 Therefore the extra overhead for calculating the maximum fd seems
495 to be more than compensated. Is this correct? In any case,
496 scm_internal_select will be much faster with this info.
497 (scm_select, fill_select_type, set_element): Don't accept any kind
498 of object in the file descriptor list or vector.
500 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
502 * iselect.c (finalize_fd_sets): Bugfix.
504 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
506 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
507 when using scm_internal_select (since we might switch to another
510 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
512 * simpos.c (scm_system): always define: use sysmissing if not
513 available. Check for HAVE_SYSTEM instead of _Windows (does
514 Windows lack system or does it have an unusable one?).
515 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
516 Let the argument be optional: if not supplied, call system(NULL).
518 * ports.c (scm_close_port): relax the type check from OPPORTP to
519 PORTP; closing a closed port is allowed.
521 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
523 * fports.c (scm_fgets): Return if the last char in a chunk is
524 newline. When fgets returns a string whose length is `size-1', it
525 is ambiguous whether a whole line was retrieved, so we must check
526 explicitly whether a line terminator is present.
528 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
530 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
531 before taking the CDR. (Thanks to Harald Meland.)
533 * filesys.c (scm_stat): Slightly optimized.
535 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
537 * ports.c (scm_close_port): Make sure the port is open before
540 * guile-snarf.in: Pass args through to gcc in a way that preserves

554 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
555 errno macro expansion of this field name. (errno is a C
556 preprocessor macro on some systems.)
558 1997-11-29 Tim Pierce <twp@skepsis.com>
560 * iselect.c: Doc fix.
562 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>

597 * iselect.c (coop_next_runnable_thread,
598 coop_wait_for_runnable_thread): Disable interrupts so that no
599 async is executed before a potential error_revive.
600 (scm_internal_select): Disable interrupts during the parts of the

611 replacement in iselect.c.
612 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
613 coop_join): If GUILE_ISELECT enabled, use
614 coop_wait_for_runnable_thread instead of
615 coop_next_runnable_thread.
616 (usleep, sleep): New replacements for system functions if
617 GUILE_ISELECT is enabled.
619 * coop-threads.h: Declare coop_wait_for_runnable_thread.
621 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
623 * filesys.c: Added #include "iselect.h". Moved FD-macros to

625 scm_internal_select. (See NEWS.)
627 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
629 * init.c: Call scm_init_iselect.

634 1997-11-27 Tim Pierce <twp@skepsis.com>
636 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
637 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
638 and scm_must_free, since ultimately the string returned will be copied
639 by scm_makfrom0str anyway. Also, read any characters that may have
640 been pushed onto the port with scm_ungetc.
641 * ports.c (scm_generic_fgets): Same as for scm_fgets.
642 * ioext.c (scm_read_line): Free string after Guilifying it.

654 gh_repl (argc, argv).
656 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
658 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
659 and to invoke scm_shell().
660 (gh_launch_pad): took out the loading of boot-9.scm from here,
661 since it is probably best to let the user control that. In fact,
662 gh_repl() now invokes scm_shell() which does that.
664 1997-11-23 Mark Galassi <rosalia@cygnus.com>
666 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
669 1997-11-22 Tim Pierce <twp@twp.tezcat.com>

691 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
693 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
694 configure.in was changed).
696 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
698 * Makefile.am (modinclude_HEADERS): Include readline.h here.

714 scm_set_current_error_port): Likewise
715 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
716 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):

730 exactly what we want to leave in to detect substrings.
731 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
732 * tags.h: Fix diagrams and comments describing the S tag bit;
733 remove vestigial remarks about the D tag bit.
734 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
735 * strings.c: Formatting tweaks.
737 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
738 variable first; then SCHEME_LOAD_PATH, with a warning message.
739 (scm_parse_path): New function.
740 * script.c: Doc fixes.
742 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>

756 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
758 * gh_data.c (gh_vector_set_x): changed name to make it consistent
759 with the ! -> _x mapping when going from Scheme to C.
761 1997-10-19 Mark Galassi <rosalia@cygnus.com>
771 (gh_assoc): added these gh_ functions implemented as macros.
773 * gh_predicates.c (gh_null_p):
774 (gh_string_equal_p): added these two missing predicates.
776 * gh_list.c (gh_append):

787 * tags.h (scm_tc7_substring): Changed the comment and code to
788 conform with the changes below. Folks! We have suddenly two new
789 free tc7 codes!!! Jummy, jummy!
791 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>

853 * gh_test_c.c (c_vector_test): some improvements on the vector
856 * gh.h (gh_vector): this used to exist but do the wrong thing.
857 Now it (almost) does the right thing, though it takes a list
858 instead of the individual arguments. I need to see how it could
860 (gh_list_to_vector): added this function as a macro. Corresponds
861 to Scheme's (list->vector ...).
862 (gh_vector_to_list): added this function as a macro. Corresponds
863 to Scheme's (vector->list ...).
865 * gh_data.c (gh_vector_ref): renamed from gh_vref to
866 gh_vector_ref, so that it resembles the Scheme routines more.

868 resembles the Scheme routines more.
869 (gh_make_vector): this used to be (stupidly) called gh_vector().
870 This is the right name, since it does the same thing as the Scheme
871 (make-vector ...) procedure.
873 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
875 * ports.h: #include "libguile/print.h"

890 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
892 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
893 macros should by convention not test for NIMPness.)
894 (SCM_COERCE_OPORT): Adjust indentation.
896 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
897 SCM_NIMP test before SCM_PRINT_STATE_P.

907 printing: Also output hex code of vtable so that type identity
908 will be indicated as well.
909 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
910 Removed struct_printer_var; Removed struct-vtable-offset;
911 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
912 vtable-offset-user): New constants.
914 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.

917 the type represented by this vtable.
919 * print.c (scm_iprin1): Don't print arguments of macro
920 transformers. (They are always: exp env.); Bugfix: Unmemoize
921 transformer source with correct environment.
923 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
925 Streamlining of call-with-dynamic-root:

930 (cwdr_handler): New function.
931 (scm_internal_cwdr): New function to perform the function of cwdr
932 but take args that are more useful to C code. Also, the handler
933 is now invoked *outside* of the new dynamic root, like the docs
934 say. We no longer have to catch absolutely all errors, the caller
935 is responsible for using a handler that does not throw, if he
937 (cwdr): Reimplemented in terms of scm_internal_cwdr.
938 * root.h (scm_internal_cwdr): New prototype.
940 Even more but risky streamlining:
942 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
943 allocation of the jumpbuf of a root continuation. The changes
944 below are controlled by it. They are now deactivated.
945 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
946 the JMPBUF of the scm_rootcont to NULL before returning.
948 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
949 when they are non-NULL.

953 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
955 * gc.c (scm_done_malloc): New function.
956 gc.h (scm_done_malloc): New prototype.
958 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
959 (struct scm_print_state) [revealed]: New field.

966 (scm_print_state_vtable): New variable.
967 (scm_free_print_state): Set `revealed' field to false.
968 (scm_iprin1): Call user supplied closure printer with
969 scm_printer_apply. Print in the traditional way when there isn't

971 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
972 Accept a port/print-state pair in addition to just a port.
973 (scm_prin1): Don't return the print_state to the pool when it has
975 (scm_printer_apply): Set `revealed' field of print_state to true.
976 (scm_init_print): Set scm_print_state_vtable.
977 (print_state_fluid, print_state_fluid_num): Removed.

984 * Makefile.in: Regenerated with automake 1.2c.
986 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
988 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
989 was looping endlessly.
991 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
993 * strports.c (scm_eval_string): Don't close the port.
995 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
996 former returns a nice normal integer. (Thanks to Daniel
999 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1001 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1002 makefile variable as a build parameter called LIBS. The
1003 build-guile program will use this, for the time being.
1004 * Makefile.in: Regenerated.
1006 Thanks to Shiro Kawai:
1007 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1008 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1011 * Makefile.in: Regenerated with automake 1.2a.
1013 * script.c (scm_compile_shell_switches): If we hit the -c or --
1014 arguments, don't set the car of (command-line) to scm_usage_name,
1015 the prettified name of the guile executable; give it the full
1016 path, the way shells usually handle $0.
1018 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1020 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1021 Scheme-level name `array-map' and renamed `serial-array-map' to
1022 `serial-array-map!'.
1024 * backtrace.c: Introduced exception handlers which now enclose
1025 `display-error' and `display-backtrace' so that error reporting
1026 won't get into infinite loops if an error occurs during displaying
1027 of the error. This can very easily happen with user supplied
1028 print call-back routines.
1030 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1032 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1033 the names `serial-array-map' and `array-map' should be removed.)
1035 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1037 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1038 Added #include "objects.h"
1040 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1041 Add #include "feature.h".
1043 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1044 (modinclude_HEADERS): Added objects.h.
1046 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1047 This test is needed at many places in the code and should be
1048 abstracted. (Motivated by the need of this test in libguiletk.)
1050 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1051 (scm_eval_string), load.c (scm_primitive_load,
1052 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1053 Use SCM_EOF_OBJECT_P.
1055 * eval.c (scm_init_eval): Add feature `delay'.
1057 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1059 * scmhob.h: Removed.
1061 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1063 * list.h (SCM_LISTn): New macros. Make list creation in C code
1064 prettier. The idea comes from STk.
1066 * sequences.h, sequences.c, append.h, append.c: Removed. These
1067 files implemented non-R4RS operations which would encourage
1068 non-portable programming style and less easy-to-read code.
1070 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1073 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1074 sequences.h, #include append.h.
1076 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1079 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1081 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1083 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1085 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1087 * eval.c: Added #include "objects.h"
1089 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1092 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1093 adjacent smob numbers.
1095 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1097 * procprop.h: Added declaration of scm_i_inner_name.
1099 * gsubr.c: New global symbol scm_i_inner_name.
1101 * debug.c (scm_procedure_name): Try procedure property
1102 `inner-name' if `name' fails.
1104 * print.c (scm_iprin1): Use scm_macro_name.
1106 * eval.c (scm_m_define): Give names to macros as well; Only the
1107 first top-level definition gives a procedure/macro a name.
1108 Otherwise confusing names can turn up in backtraces.
1109 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1110 `name'; Give names to macros as well.
1112 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1113 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1116 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1118 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
1120 (prinmacro): Removed. The code has been moved/merged into print.c
1121 in order to decrease code redundancy. We want macros to print in
1122 a way equivalent to procedures, and it would be silly to duplicate
1123 the required code. (We don't want to maintain two places.)
1124 (macrosmob): Print field is now a NULL pointer.
1126 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1127 scm_macro_transformer): New prototypes.
1128 (scm_tc16_macro): Declared.
1130 * * print.c (scm_iprin1): Added code for printing of macros. Macros
1131 are now printed in a way equivalent to procedures.
1133 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1135 * procs.h (scm_closure_p): Added declaration.
1137 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1139 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
1140 Shouldn't pass "heap" as the subr name.
1142 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1144 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
1145 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
1146 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1147 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1148 SCM_BOOL_T. Any non-false value is true.
1150 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1152 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1153 scm_gensym): Added prototypes.
1155 * symbols.c (scm_gensym): New function. This will speed up
1156 certain types of applications (such as macro systems) which
1157 generate lots of symbols.
1159 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1161 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
1163 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
1165 * unif.c (scm_shap2ra): tighten the checking of the array dimension
1166 specifier, since (2) or (2 . 3) would cause SEGV.
1167 (scm_transpose_array): more argument checking fixes.
1169 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1171 * Makefile.in: Regenerated.
1173 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1175 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
1177 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1179 * error.c, error.h (scm_error_callback): Removed (see NEWS).
1181 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
1183 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
1184 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
1187 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
1188 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1189 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
1190 scm_array_p, scm_array_rank, scm_array_dimensions,
1191 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
1192 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
1193 scm_array_prototype): Added case scm_tc7_wvect.
1195 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
1197 * errno.h: prototype for scm_strerror.
1198 * error.c (scm_strerror): new procedure.
1200 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1202 * list.c (scm_list_append_x): Allow non-pair as last argument.
1203 This is consistent with the R4RS append and is probably the
1204 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1206 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1208 * stime.h: prototype for scm_times.
1209 * stime.c (scm_times): new procedure.
1210 * ioext.c (scm_fseek): if the first argument is a file descriptor
1212 (scm_ftell): if the first argument is a file descriptor call lseek
1214 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
1215 * filesys.c (scm_chmod): if the first argument is a file descriptor,
1217 (scm_chown): if the first argument is a port or file descriptor,
1219 (scm_truncate_file): new procedure.
1220 Add DEFER/ALLOW INTS to a few other procedures.
1221 (scm_fsync): new procedure.
1222 (scm_open_fdes): new procedure.
1223 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
1225 (scm_fcntl): the first argument can now be a file descriptor. The
1226 third argument is now optional.
1228 * posix.c (scm_execl, scm_execlp): make the filename argument
1229 compulsory, since omitting it causes SEGV.
1230 (scm_sync): return unspecified instead of #f.
1231 (scm_execle): new procedure.
1232 (environ_list_to_c): new procedure.
1233 (scm_environ): use environ_list_to_c. disable interrupts.
1234 (scm_convert_exec_args): take pos and subr arguments and
1235 improve error checking.
1237 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1239 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1240 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1241 argument to SCM_ASSERT. Furthermore, the name of the function
1242 should be passed as first argument when signalling
1243 SCM_WNA. (Thanks to Thomas Morgan)
1245 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1246 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1247 dispatches on the number of actual args has a default case
1248 reporting an internal error. This is a vestige from a version
1249 that mallocated a SCM vector to hold the arguments. In the
1250 current version this check is too late: if it ever happens we will
1251 have already overstepped the bounds of the array.
1253 Also, the patch [...] adds a check for too many actual arguments."
1255 mdj: Removed check for "internal programming error".
1257 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1259 * gh_io.c (gh_write): New function.
1261 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
1262 throw.c (scm_internal_stack_catch): New sibling to the other catch
1263 functions. Code moved from gh_eval.c.
1264 throw.h: Added header.
1265 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
1266 scm_internal_stack_catch.
1268 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1270 * ioext.h: fix up prototypes.
1271 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
1272 Scheme name is now dup->fdes.
1273 (scm_dup_to_fdes): make the second argument optional and
1274 fold in the functionality of scm_primitive_dup.
1275 (scm_primitive_dup): deleted.
1277 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1279 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
1280 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
1281 ultrix are defined. Use setvbuf instead of setbuf.
1282 (scm_setvbuf): new procedure.
1283 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
1284 (scm_setfileno): moved from ioext.c.
1285 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
1286 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
1288 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1290 * fluids.c (scm_fluid_p): New function.
1291 * fluids.h (scm_fluid_p): New prototype.

1295 * print.c (scm_iprin1): Enter printed structures into the print
1296 state as nested data while they are printed.
1297 (print_state_fluid, print_state_fluid_num): New variables.
1298 (scm_init_print): Initialize them.
1299 (scm_iprin): If print_state_fluid carries a print_state, use that
1300 instead of creating a new one.
1301 (scm_printer_apply, apply_stub, struct apply_data): New
1302 definitions to help with calling printer functions written in
1304 * print.h (scm_printer_apply): New prototype.
1306 * struct.c (scm_print_struct): Use scm_printer_apply to call the
1307 user defined struct printer.
1309 * dynwind.c (scm_dowinds): Handle fluids on the wind list.

1317 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
1318 SCM_ASSERT: arg comes before pos.
1320 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1322 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
1323 to a list of length zero correctly.
1325 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1327 Supply an `fgets' method for port objects to do fast line i/o.

1341 * ioext.h: removed scm_duplicate_port prototype.
1343 * ioext.c (scm_primitive_dup2): return the new file descriptor
1344 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
1346 (scm_fdopen): bug fix: don't try to make port unbuffered until its
1347 stream has been set.
1348 (scm_duplicate_port): deleted, there's now an implementation in
1350 (scm_primitive_dup2): do nothing if newfd == oldfd.
1352 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
1354 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the

1358 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
1360 * fluids.c (next_fluid_num): don't do
1361 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
1363 * ports.h: prototypes too.
1364 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
1366 * fports.h: prototype too.
1367 * fports.c (scm_evict_ports): moved from ioext.c.
1369 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>

1376 and ports (scsh compatible).
1378 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
1381 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
1383 * fluids.c, fluid.h: New files.
1384 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
1385 (modinclude_HEADERS): Added "fluids.h"

1394 (scm_make_root): Call scm_copy_fluids to make fluid bindings
1395 unique for the new root when it has a parent.
1397 * smob.h: Include "libguile/print.h" to make scm_print_state
1400 * dynl.c (free_dynl_obj): New function to free the dynamic object
1401 data. (dynl_smob): Use it.
1402 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
1403 the dynamic object data below the linking of the object to avoid
1404 memory leak when the linking code throws an error. Now the code
1405 leaks a whole dynamically linked library when must_malloc throws,
1406 but that should be much less likely.
1408 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
1410 Changes to compile under gnu-win32, from Marcus Daniels:
1411 * stime.c (tzset): If tzset isn't provided, make it a NOP.
1412 (scm_localtime): Change SCM_EOF to SCM_EOL.
1413 (scm_mktime): Likewise.
1414 * socket.c: Don't include sys/un.h unless autoconf tells
1415 us Unix domain sockets are available.
1416 (scm_fill_sockaddr): Ignore Unix domain code.
1417 (scm_addr_vector): Likewise.
1418 (scm_init_addr_buffer): Likewise.

1422 * scmsigs.c (scm_pause): Don't include unless pause was found
1424 * posix.c (scm_getgroups): Don't include unless support function
1425 was found during autoconf (in this case, getgroups).
1426 (scm_setpwent): For setpwent.
1427 (scm_setegid): For setegid.
1428 * net_db.c (scm_inet_netof): Don't include unless support
1429 function was found during autoconf (in this case, inet_netof).
1430 (scm_lnaof): For inet_lnaof.
1431 (scm_inet_makeaddr): For inet_makeaddr.

1443 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
1444 scm_misc_error, not SCM_EOF.
1446 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
1447 arguments for formatting the error message, not SCM_BOOL_F. I
1448 think this is left over from the (eq? '() #f) days.
1450 * read.c (recsexpr): Give this a dummy definition if
1451 DEBUG_EXTENSIONS isn't #defined.
1453 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
1455 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
1458 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>

1465 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
1466 alloca.lo will be included in @LIBLOBJS@. Something better than
1467 this should be possible.
1468 * Makefile.in: Regenerated.
1470 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1472 * simpos.h: prototype for scm_primitive_exit.
1473 * simpos.c (scm_primitive_exit): new procedure, terminates the
1474 process without unwinding the stack.
1476 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
1478 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
1479 argument and logior its components together, so the user doesn't
1480 have to do this explicitly. Also, if regexp/basic is supplied, then
1481 turn off REG_EXTENDED.
1482 (scm_init_regex_posix): New regexp/basic symbol.
1483 (REG_BASIC): #define this if it is not already present.
1485 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1487 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.

1495 * script.c (scm_compile_shell_switches): Add 1997 to copyright
1496 years in usage message.
1498 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
1499 * Makefile.in: Regenerated.
1501 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
1502 flag; I don't think we support it.
1503 (scm_make_regexp): Make sure the user doesn't pass the
1506 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
1508 (scm_init_regex_posix): Define constants for the REG_mumble flags;
1509 name them according to the SCSH convention: regexp/mumble.
1511 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
1513 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
1515 * Makefile.am (libpath.h): Include the values of all the standard
1516 Makefile directory variables. Print a message, but don't print
1518 (versiondat.h): Print a message, but don't print all the commands.
1519 * load.c: #include "alist.h".
1520 (init_build_info): New function.
1521 (scm_init_load): Call it.
1522 * Makefile.in: Regenerated.
1524 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
1526 * root.c: Establish a reliable catch-all handler for the new root.
1527 After all the Scheme handler function might signal an error too,
1528 and we don't want to lose that.
1529 (cwdr_inner_body): Renamed from cwdr_body.
1530 (cwdr_outer_body): New function, to establish the user's handler,
1531 and pass control to cwdr_inner_body.
1532 (cwdr): Establish the reliable catch-all handler here, and pass
1533 control to cwdr_outer_body.
1534 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
1535 the user's handler through to cwdr_outer_body.
1536 * throw.c (scm_handle_by_message): Move guts into....
1537 (handler_message): New static function.
1538 (scm_handle_by_message_noexit): New function.
1539 * throw.h (scm_handle_by_message_noexit): New prototype.
1541 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
1542 across this. Only works on GCC. Otherwise, we hope for the best.
1543 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
1544 the feeling that real thread systems will not need this...
1546 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
1548 Try to detect when people are using one version of libguile and a
1549 different version of ice-9. People have been skewing things and
1550 sending in bug reports.
1551 * Makefile.am (versiondat.h): New file to generate.
1552 * version.c: #include "versiondat.h", to get version info.
1553 (scm_libguile_config_stamp): New function.
1554 * script.c: #include "version.h".
1555 (scm_compile_switches): Call scm_version to get version number.
1556 * scmconfig.h.in, Makefile.in: Regenerated.
1557 * Makefile.in: Regenerated.
1559 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
1560 primitive definitions under their Scheme names.
1562 * Makefile.am (libguile_la_LDFLAGS): Update library version to
1563 1:2. Helps avoid confusion between installed and uninstalled libs.
1565 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
1568 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
1569 backslash from definition; this should be used like: GDB_INTERFACE;
1571 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1573 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
1574 new port unbuffered until its stream has been set.
1576 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
1578 * ports.h: new prototype.
1579 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
1581 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
1583 Make things compile neatly under Sun's C compiler.
1584 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
1585 * extchrs.c (xmbtowc): Make the second arg a normal char, not
1586 unsigned, because that's what the ANSI function takes.
1587 * extchrs.h (xmbtowc): Corresponding change to prototype.
1588 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
1590 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
1591 argument plain char *.
1592 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
1594 * tag.c (scm_tag): Remove unreachable statement.
1595 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
1596 top of the word, it should be unsigned.
1598 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
1599 is defined, to avoid warnings; it's only used in the
1600 conflict-checking code. Which might go away anyway.
1601 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
1602 conditionals; put the label definition in an #if too, to stifle
1605 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
1606 ChangeLog-threads in the distribution.
1607 * Makefile.in: Regenerated.
1609 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1611 * guile-snarf.in: Changed regexp to support CPPs that insert
1612 whitespace between lexical tokens (which munges the `%%%' snarf
1615 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1617 * load.c (scm_init_load_path): Append $(datadir)/guile to
1618 %load-path, so modules do not have to be installed in Guile's
1619 current version directory.
1621 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
1623 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
1624 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
1625 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
1626 call the sysdep functions with deferred ints.
1627 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
1628 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
1629 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
1632 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
1635 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
1637 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
1639 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
1641 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
1644 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
1646 * eval.c (scm_lookupcar1): New procedure to cope with a race
1647 condition during lookup (when using threads).
1648 (scm_lookupcar): Implement in terms of scm_lookupcar1.
1649 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
1652 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
1654 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
1655 supplied. (Change from Tim Pierce.)
1657 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
1659 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
1660 23:47:01 1997" changelog: Slots are now initialized with `#f' by
1661 default and not `()'. `#f' is the canonical non-value in Scheme,
1664 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1666 * struct.c (struct_printer): New variable that holds a handle on
1667 the Scheme variable *struct-printer*. This variable can be set by
1668 Scheme code to override the printing of structures.
1669 (scm_print_struct): If struct_printer is set, call it. If it is
1670 not set, or returns #f, print the structure in the old fashion.
1671 Include "eval.h" for scm_apply.
1673 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
1675 * struct.c (scm_struct_ref, scm_struct_set_x): Use
1676 scm_struct_i_n_words to get the number of fields, not
1677 -scm_struct_n_extra_words.
1679 On the route to fancier struct printing:
1680 * struct.c (scm_print_struct): New function to print a structure.
1681 Include "genio.h" to support it. This function doesn't do
1682 anything interesting right now, but I think it should be here
1684 * struct.h: Include "print.h" and add prototype for
1686 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
1687 print structures ourself.
1689 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
1691 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
1692 before applying the handler in case it doesn't return.
1694 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
1696 * scmsigs.h, async.h: updated.
1698 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
1701 * posix.c (scm_uname): interpret only negative values as an error.
1702 Solaris normally returns a positive value.
1704 * script.c (scm_compile_shell_switches): if we are not going into
1705 an interactive repl, set scm_mask_ints to zero so that asyncs can
1708 * simpos.c (scm_system): don't ignore/unignore signals around
1711 * posix.c (scm_open_pipe): don't ignore/unignore signals around
1714 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
1715 done in boot-9.scm instead.
1717 * scmsigs.c, async.c: Major rewriting of signal handling code.
1718 (scm_sigaction): new procedure.
1719 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
1721 (scm_raise): return unspecified, throw error on failure.
1723 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
1725 * regex-posix.c (scm_init_regex_posix): Register the "regex"
1726 feature, to help boot-9.scm decide whether to import the regex
1729 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
1731 * eval.c: Include scmconfig.h at the beginning of the file so that
1732 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
1735 * regex-posix.c: #include "_scm.h" before conditionally #including
1736 <regex.h>; the former defines HAVE_REGCOMP.
1738 * regex-posix.c: #include <regex.h> conditionally, so the file is
1739 CPP'able (for dependency scanning) even on systems that don't have
1742 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
1744 Add new R4RS-compliant syntax for keywords.
1745 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
1746 regardless of the setting of the `keywords' read option.
1747 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
1748 can be re-read no matter what the setting of the `keywords' read
1751 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
1753 Add support for POSIX regular expressions.
1755 * regex-posix.c, regex-posix.h: New files. (Some code
1756 is taken liberally from rx/rgx.c in the old Guile dist.)
1758 * init.c: Include regex-posix.h.
1759 (scm_boot_guile_1): Call scm_init_regex_posix.
1761 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
1762 Add regex-posix.[ch] sources.
1763 * Makefile.in: Regenerated.
1765 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
1766 to do this automatically? It didn't for me, bleh.)
1768 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
1770 * fports.c (print_pipe_port): New function.
1771 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
1772 latter doesn't even take the right arguments.
1774 * Makefile.am: Increment shared lib revision number. I think
1775 sometimes the uninstalled Guile finds the installed shared lib;
1776 Gord says doing this might help. As things turned out, I can't
1777 say whether it does.
1778 * Makefile.in: Regenerated.
1780 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
1781 passing it as the closure argument to scm_boot_guile. (Bill
1784 * ports.c (print_void_port, putc_void_port, puts_void_port,
1785 write_void_port, flush_void_port, getc_void_port, close_void_port,
1786 noop0): Use ANSI prototypes instead of K&R declarations, so the
1787 initialization of void_port_ptob gets aggressively type-checked.
1788 Fix arguments of print_void_port and write_void_port. (Bill

1822 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
1824 * script.c (scm_find_executable): Use prototype-style definition
1825 here; apparently it's not quite right to have const in a prototype
1826 and then use a K&R declaration. I wonder if stuff like this will
1827 go away if we compile with -Wrequire-prototypes, or whatever that
1828 is... (Bernard URBAN)
1830 * scmhob.h: New text from Bernard URBAN.
1832 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
1834 * script.c: Don't #define const on hpux. Configure takes care of
1835 this. (Thanks to Larry Schwimmer.)
1837 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
1838 decide whether to #include <unistd.h>, instead of listing a bunch
1839 of systems. Don't #include stdio twice. Removed dyked-out
1840 definition of scm_find_impl_file.
1842 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
1844 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
1845 library version info to 1:0.
1846 * Makefile.in: Regenerated.
1848 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

1852 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
1853 throw.c: Update copyright years; these files have been worked on
1854 significantly in 1997, but only had copyright years for 1996.
1855 Also, change name of copyright holder on some from Mikael
1856 Djurfeldt to Free Software Foundation; he has signed papers
1857 assigning the changes to the FSF.
1859 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
1860 reason not to give the user the option.
1862 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
1863 Return #f on end-of-file when scanning table (i.e. when called
1864 with no arguments). Try to catch errors, when we can.
1865 * posix.c (scm_getgrgid, scm_getpwuid): Same.
1867 * script.h (scm_shell_usage, scm_compile_shell_switches): New
1868 external declarations. These are useful.
1870 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
1872 * posix.c: don't include <sys/select.h> or define macros for
1873 select, since they were not used in this file.
1875 * filesys.c (scm_select): make the fifth parameter microseconds,
1876 not milliseconds. let the fourth parameter be either a real value
1877 or an integer or #f. The first, second and third arguments can
1878 now be vectors: the type of the corresponding return set will be
1880 (set_element, get_element): new static procedures.
1882 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
1884 * strports.c (scm_eval_string): New function.
1885 (scm_eval_0str): Trivially re-implemented in terms of
1887 * strports.h (scm_eval_string): New extern decl.
1889 * net_db.c (h_errno): Add extern decl for this.
1891 * fports.c (local_pclose): New function.
1892 (scm_pipob): Use it in the initializer here.
1895 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
1896 Use a meaningful error message when signalling an error. For
1897 this, scm_gethost must check h_errno rather than errno.
1899 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
1901 * Makefile.in: Regenerated, using automake-1.1p.
1903 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
1905 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
1906 not SCM_UNSPECIFIED.
1908 * script.c (scm_compile_shell_switches): don't append (quit) if
1910 (scm_shell): call scm_exit_status and exit on the result of the
1913 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
1915 Ensure that shared substrings are handled properly when passed to
1916 a system call or other foreign function. Many thanks to Tim
1918 * symbols.h (SCM_COERCE_SUBSTR): new macro.
1919 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
1920 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
1921 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

1936 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
1938 * error.c (scm_error): Add newline to error message.
1940 * init.c (scm_init_standard_ports): Doc fix.
1942 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1944 * dynl-shl.c: Completely replaced with new code from Bernard
1947 * script.c (scm_ice_9_already_loaded): New variable.
1948 (scm_compile_shell_switches): Use it.
1950 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1952 * filesys.c (scm_input_waiting_p): add missing third argument to
1955 * stime.c (scm_localtime): copy the result of localtime before
1956 calling gmtime in case they share a buffer.
1957 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE

1964 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
1966 * Makefile.am (check-local): New target, which causes 'make check'
1967 to run gh_test_c and gh_test_repl, with some trivial input.
1968 * Makefile.in: Rgnrtd.
1970 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>

1975 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
1977 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
1978 sure how this was supposed to work.
1979 (scm_async_click): don't send SCM_TICK_SIGNAL.
1980 (scm_init_async): don't initialize %tick-thunk.
1982 * the following change doesn't affect the Scheme interface:
1983 gc-thunk is called at the end of garbage collection. however it's
1984 no longer implemented by pretending it's a signal.
1986 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
1987 system async corresponding to scm_gc_thunk.
1988 * async.h: declare scm_gc_async.
1989 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
1990 gc-thunk directly, instead of going through a signal handler.
1991 (scm_gc_async): new variable, points to the GC system-async.
1992 (scm_init_async): save the GC async as scm_gc_async instead
1993 of using system_signal_asyncs.
1994 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
1996 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
1998 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
1999 Don't screw up if we're interrupted.
2000 * Makefile.in: Regeneradet.
2002 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2004 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2006 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2007 we're not using AM_INIT_GUILE_MODULE any more.
2008 * Makefile.in: Reneregated.

2013 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2014 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2016 Get 'make dist' to work again.
2017 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2018 * Makefile.in: Regenerated, like a surry without a fringe on top.
2020 Changes for reduced Guile distribution: one configure script,
2022 * configure.in, configure: Removed.
2023 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2024 real configure script lives.
2025 * Makefile.in, scmconfig.h.in: Regenerated.
2027 * init.c: #include "script.h", to get prototype for script.c's
2030 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2032 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2033 scm_must_malloc, not raw malloc.
2035 * script.c (scm_compile_shell_switches): Dyke out debugging output
2038 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2040 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2042 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2043 system has them. Hope this is safe. Previously
2044 sys/timeb.h was included if HAVE_FTIME was defined or if
2045 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2046 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2048 * ioext.c (scm_setfileno): add missing third argument to
2049 scm_misc_error call.
2051 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2053 * eq.c (scm_equal_p): Correctly compare strings of different
2054 varieties. (Thanks to Tim Pierce.)
2056 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2058 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2059 #! block comment must occur on a line all by itself.
2061 Move most of the guts of shell command processing into libguile,
2062 so guile.c can be very small (and eventuallly auto-generated. (I
2063 mean, generated mechanically, not self-generated. Hmm.))
2064 * guile.c, script.c, script.h: New source files.
2065 * init.c (scm_boot_guile_1): Call scm_init_script.
2066 * libguile.h: #include "script.h".
2067 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2068 targets, for new executable.
2069 (libguile_la_SOURCES): Mention script.c.
2070 (modinclude_HEADERS): Add script.h.
2071 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2072 not dynamic linking is enabled. This is because we're generating
2073 executables now. Move CY_AC_WITH_THREADS call after those, so the
2074 values of cy_cv_threads_libs captures the libs chosen above.
2075 * Makefile.in, configure, aclocal.m4: Regenerated.
2077 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2078 We don't maintain this interface any more, and it just confuses
2081 * alloca.c: #include <scmconfig.h>, not <config.h>.
2082 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2083 it'll get included in disties.
2085 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2087 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2088 be distributed, because they confuse people.
2089 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2091 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2093 * configure.in: check for presence of gethostent (not present on
2094 OpenBSD by default).
2095 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2096 * configure, scmconfig.h.in: Regenerated.
2098 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2100 * backtrace.c (scm_backtrace): Split message string across
2101 newlines properly. GCC is more tolerant of this than other

2110 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2112 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2113 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2114 coop-threads.c.cygnus, coop-threads.h.cygnus.
2115 * configure.in: If we're using threads, include threads.o in
2117 * _scm.h, libguile.h: threads.h lives in this directory now.
2118 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2119 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2120 currently used, but brought along for information's sake.
2121 * ChangeLog-threads: log from old 'threads' directory.
2122 * Makefile.in, configure: Rebuilt.
2124 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2126 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2129 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2131 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2133 Merge GH interface library into libguile.

2135 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2136 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2137 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2139 (EXTRA_libguile_la_SOURCES): ... here.
2140 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2141 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2142 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2143 New variables, describing how to build the gh test programs.
2144 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2145 build the test programs, and we probably should have been linking
2146 libguile.la against them all along, to support AIX shared libs.
2147 Add cflags for threads to CFLAGS; add libs for threads to new
2148 variable THREAD_LIBS, used in Makefile.am.
2149 * ChangeLog-gh: log from old `gh' subdirectory.
2150 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2152 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2154 * acconfig.h: Undo change of Apr 9; including the definition of
2155 PACKAGE in the guile headers conflicts with applications' own
2157 * scmconfig.h.in: Regenerated.

2168 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2170 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2171 have S_IFSOCK. This is the case under Ultrix.
2173 * posix.c (scm_status_exit_val, scm_status_exit_val,
2174 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2175 Ultrix versions of WIFSTOPPED, etc., which assume that their
2176 arguments are lvalues (hmm).
2178 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2180 * eval.c: Doc fixes.
2182 * throw.c: Doc fixes; rearranged.
2184 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.

2188 * acconfig.h: Added entry for PACKAGE.
2189 * scmconfig.h.in: Regenerated.

2192 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2193 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
2195 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
2197 * Makefile.in: Rebuild.
2199 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2201 * stime.c (scm_mktime): take an optional zone argument.
2202 (scm_localtime): check putenv return value.
2203 (scm_strftime, scm_strptime): moved from posix.c. move #include
2205 stime.h, posix.h: update prototypes.
2206 (bdtime2c, setzone, restorezone): new static procedures.
2207 (scm_mktime, scm_strftime): use them.
2208 (scm_strftime): don't call mktime before strftime. Use
2209 filltime for return value.
2210 (filltime): convert NULL zname to #f.
2211 (scm_strptime): return a count of characters consumed, not
2212 the remaining string.
2214 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2216 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
2217 (scm_mktime): likewise.
2219 Uncomment localtime and mktime.
2221 * configure.in: add AC_STRUCT_TIMEZONE.
2223 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2225 * stime.c (scm_init_stime): don't define ticks/sec.
2226 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2227 return value problem and is still portable.)
2229 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2231 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2232 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2233 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2234 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2235 cpp_err_symbols.c): Corresponding changes.
2236 * Makefile.in: Regenerated.
2238 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2240 * posix.c (scm_putenv): don't check HAVE_PUTENV.
2241 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
2242 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
2243 * putenv.c: new file, from sh-utils 1.12.
2245 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2246 since allocation isn't for Scheme objects.
2247 (scm_putenv): copy strings before placing in the environment.
2249 * stime.c (scm_current_time): throw an error if time returns -1,
2250 instead of returning #f.
2251 (scm_get_internal_real_time, scm_get_internal_real_time): use
2252 scm_long2num for return value instead of SCM_MAKINUM.
2254 * stime.h: prototypes updated.
2256 * stime.c (scm_time_in_msec): apparently unused, deleted.
2258 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2260 * configure.in: check for gettimeofday.
2262 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2263 which may be more usefully portable than a gettimeofday interface.
2265 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2267 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not

2278 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2280 * posix.c (scm_mknod): split the mode argument into type and perms
2281 arguments, like the extra fields returned by stat.
2283 * fports.c (scm_pipob): set the close, free and print procedures.
2284 (scm_close_pipe): new procedure.
2286 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2287 define them in boot-9.scm
2289 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2291 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
2292 wan't defined. Don't include fd.h.
2294 * Previously fd.h was regenerated whenever configure was run,
2295 forcing a couple of files to be recompiled.
2297 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
2298 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
2299 Check for _fileno as well as _file.
2301 * ioext.c: don't fd.h.
2302 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
2305 * Change the stratigy for getting information about errno
2306 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
2307 generating lists of symbols during the build process, which will
2308 not always work, include comprehensive lists in the distribution.
2309 To help keep the lists up to date, the "check_signals" and
2310 "check_errnos" make targets can be used.
2312 * configure.in: don't check for a command to extract errno codes.
2313 * Makefile.am: update file lists, remove errnos.list and errnos.c
2314 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
2315 check_errnos targets.
2316 (CLEANFILES): remove errnos.c and errnos.list, add
2317 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
2318 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
2319 * errnos.default: deleted.
2320 * cpp_signal.c: new file.
2321 * cpp_errno.c: renamed from errnos_get.c.
2322 * cpp_err_symbols, cpp_sig_symbols: new files.
2323 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
2324 * error.c (scm_init_error): #include cpp_err_symbols instead of
2326 * posix.c (scm_init_posix): don't intern signal symbols. #include
2329 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
2331 * strop.c (scm_i_index): allow the lower bound to be equal to the
2332 length of the string, so a null string doesn't always give an error.
2334 * posix.h: new prototypes.
2335 * posix.c (scm_status_exit_val, scm_status_term_sig,
2336 scm_status_stop_sig): new functions, as in scsh. They break down
2337 process status values as returned by waitpid.
2339 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
2341 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
2342 configure doesn't know about it.
2344 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2346 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
2348 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
2349 which defines C variables with global linkage.
2351 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2353 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
2356 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
2358 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
2359 has time to check why this doesn't work well with continuations.
2361 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
2363 * Fix shell syntax error; some shells won't tolerate
2364 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
2366 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2368 * posix.c (scm_uname): throw an error if uname fails instead
2371 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
2373 * error.c (err_head, scm_errno, scm_perror): obsolete procedures

2380 * acconfig.h: Removed PACKAGE.
2382 * scmconfig.h.in: Regenerated.
2384 * snarf.h: g++ says it's non-portable not to specify the first
2385 argument in a varargs declaration. I introduced the first
2386 argument by using preprocessor conditionals.
2388 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
2390 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
2391 (scm_freopen): use RO string macros for filename and modes.

2395 (scm_mknod): use RO string macros for path.
2397 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
2398 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
2400 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2401 use SCM_ROSTRINGP and SCM_ROCHARS.

2405 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
2408 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,

2410 support for byte vectors.
2412 * print.c (scm_iprin1): Limit number of vector elements printed
2413 according to pstate->length.
2415 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>

2420 * error.h: prototype for scm_error_scm.
2422 * error.c (scm_error_scm): new procedure, reimplements scm-error
2423 in C and uses scm_error.
2425 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2427 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
2428 pointer to the Scheme variable read-hash-procedures and intern it
2429 in scm_init_read. Modify scm_read_hash_extend and
2430 scm_get_hash_procedure to use the pointer.
2432 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2434 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
2435 (SCM_KEYWORD_STYLE): defined.
2437 * read.c (scm_read_opts): add a keywords option. This isn't a
2438 boolean option, in case someone wants to add support for DSSSL
2440 Setup scm_keyword_prefix symbol.
2441 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
2443 I've left keyword support disabled by default, since it doesn't
2444 seem to break the module system and it gives R4RS standard behaviour.
2445 It can be reactivated with (read-set! keywords 'prefix).
2447 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2449 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
2450 before constructing arbiter.
2452 * eval.c (scm_m_define): Bugfix: Check that the object is a
2453 closure before setting the procedure property!
2455 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
2457 * ports.c: Removed `ungetc-char-ready?'.
2459 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
2461 * read.c (scm_init_read): intitialise scm_read_hash_procedures
2462 (idea from Mikael: make it a pair so scm_permanent object only
2464 (scm_read_hash_extend): don't call scm_permanent_object.
2465 (ideas from Mikael): if chr is already in the list, replace its
2466 procedure instead of appending it again. If proc is #f, remove
2468 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
2470 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
2472 * gdbint.c (gdb_read): update scm_lreadr usage.
2474 * load.h: update prototypes.
2476 * load.c (scm_primitive_load, scm_read_and_eval_x,
2477 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
2479 * read.h: add prototype for scm_read_hash_extend. Change args for
2482 * read.c (scm_read_hash_procedures): new variable.
2483 (scm_read_hash_extend): new procedure.
2484 (scm_get_hash_procedure): new procedure.
2485 (scm_lreadr): use scm_get_hash_procedure instead of an argument
2486 for extended # processing.
2487 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
2488 scm_read_token): remove case_i, sharp arguments. Change callers.
2490 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
2492 * read.h (SCM_N_READ_OPTIONS): increase to 3.
2493 (SCM_CASE_INSENSITIVE_P): define.
2495 * read.c: add case-insensitive option to scm_read_opts.
2496 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
2497 to determine whether to convert symbol case.
2498 (default_case_i): definition removed.
2499 * read.c (scm_read_token): if case_i, downcase ic before doing
2502 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2504 * configure.in: Added configuration option `guile-debug'.
2505 Configure with --enable-guile-debug if you want a bunch of extra
2506 functions used for debugging when developing Guile.
2508 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
2510 * procs.c (make-cclo): New undocumented debugging procedure: Make
2511 compiled closure with internal procedure PROC and length LENGTH.
2512 Only compiled if GUILE_DEBUG is defined.
2514 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
2516 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
2518 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
2520 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
2521 with 3 or more args internally to the evaluator.
2523 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2525 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
2526 with 3 or more args internally to the evaluator. This is mainly
2527 because we don't want to pass entry and exit points of the
2528 debug support twice, but it also seems to increase the speed of
2529 the evaluator for such calls (e. g. (+ 1 2 3)).
2531 * backtrace.c (scm_display_application): New procedure:
2532 display-application; Set fancy printing parameters individually
2533 for different types of display (backtrace, error, application).
2534 (These should of course be customizable!)
2536 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
2537 clear the CHECK-flags.
2539 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2541 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
2543 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2545 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
2546 from pairs with a GLOC in the car.
2548 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
2549 otherwise `symbol-hash' will behave badly.
2550 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
2551 we get segmentation fault!
2553 * symbols.c: Added #include "weaks.h". New functions:
2554 `builtin-bindings' and `builtin-weak-bindings'. (These will be
2555 moved to an extraneous library when we split libguile.)
2557 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2559 * filesys.c (scm_stat): stat now takes fport arguments too as
2560 documented in the manual.
2562 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2564 * debug.c (scm_single_step): Bugfix: Call continuation with
2565 scm_call_continuation instead of throwing to it.
2567 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
2569 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
2570 argument wasn't declared to be optional.
2572 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2574 * stime.c (scm_init_stime): Add feature "current-time".
2576 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
2578 * throw.h: prototype for scm_exit_status.
2579 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
2580 args to derive an exit status. Allows (quit) to work from a
2582 (scm_exit_status): new function.
2585 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2587 * eval.c (scm_deval): Removed some old code.
2588 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
2590 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
2593 * symbols.c (msymbolize): Bugfix: Must initialize property list to
2596 * procs.c: Introduce the existent C function scm_thunk_p at the
2597 Scheme level as well.
2599 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2601 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
2602 used from C to easily lookup the value of a symbol in the current
2605 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2607 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
2608 scm_init_unif in this file. This will also fix a previous problem
2611 * configure.in: Added AM_MAINTAINER_MODE
2613 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2615 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
2618 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
2620 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
2621 source files that are not always included in libguile but should
2622 have their dependencies calculated by automake. This variable is
2623 recognized by automake, no further magic is needed.
2624 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
2625 to deal exclusively with *.lo files, as it seems. The *.o files
2626 are built automatically when the corresponding *.lo file gets
2629 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
2631 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
2634 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
2636 * unif.c (scm_array_set_x): minor change to argument error checking.
2638 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
2640 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
2641 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
2642 They should only be included in the library at configure.in's
2644 (libguile_la_LDADD): Include the appropriate .lo files here.
2645 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
2646 so we know when to build them (and their .lo bretheren).
2647 * configure.in (LIBLOBJS): New substituted variable. We let
2648 configure decide which .o files to include in LIBOBJS, and then
2649 put the corresponding list of .lo files in LIBLOBJS. The latter
2650 is what we pass to libtool.
2651 * Makefile.in, configure: regenerated.
2653 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
2655 * symbols.c (scm_sysintern0): New function. Contains the core of
2656 old scm_sysintern but doesn't take a second value argument.
2657 (scm_sysintern): Now uses scm_sysintern0.
2658 (scm_sysintern_no_module_lookup): Renamed to
2659 scm_sysintern0_no_module_lookup and doesn't take a second value
2660 argument any longer.
2662 * symbols.h (scm_sysintern0: Added declaration.
2664 * options.c (scm_init_opts): Use scm_sysintern0 instead of
2665 scm_sysintern when interning option keys. Otherwise we risk
2666 destroying the values of already interned variables.
2668 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
2669 scheme-level boolean (use SCM_NFALSEP).
2671 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
2673 (scm_backtrace): New function. (C version of old function from
2674 boot-9.scm) Motivation: Make it possible to display backtraces
2675 without depending on boot-9.scm. (I'm uncertain if this
2676 motivation is good enough...)
2678 * root.h (scm_root_state): Add member the_last_stack_var.
2679 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
2681 * root.c (mark_root): Mark scm_the_last_stack_var.
2683 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
2686 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
2688 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
2689 1. mark_lazy_catch didn't mark the smob.
2690 2. Both functions above have standard variants:
2691 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
2692 free_lazy_catch --> scm_free0.
2694 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
2696 * throw.c (scm_internal_lazy_catch): New function.
2697 (scm_lazy_catch): Rewritten to use it.
2698 (scm_ithrow): Handle the new lazy catch representation.
2699 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
2700 that doesn't have a jmpbuf is a lazy catch clause.
2701 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
2702 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
2703 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
2705 (scm_init_throw): Register the new lazy-catch smob type.
2706 * throw.h (scm_internal_lazy_catch): decl for new function.
2708 * throw.c (scm_internal_catch): Doc fixes.
2710 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
2711 configure.in. Including this might cause problems if applications
2712 that link against libguile include their own copies of alloca, but
2713 if they're using autoconf, they should be adding libguile to LIBS
2714 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
2715 the copy in libguile, and things will be okay. (I think.)
2717 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2719 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
2721 strop.h: move prototypes too.
2723 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2725 * posix.c (scm_init_posix): don't intern EINTR since it's now done
2728 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
2729 etc. I deleted them from filesys.c long ago, but didn't
2730 notice they were here too (although ineffective since
2731 sys/stat.h wasn't included).
2733 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
2735 * eval.c: Don't define alloca in GCC case. gcc will automatically
2736 use __builtin_alloca if appropriate.
2738 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2740 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
2741 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
2742 that values of automatic variables are preserved. See comments
2743 for safe_setjmp for details.
2745 Change from Thomas Morgan:
2746 * variable.c: Include eq.h.
2747 (var_equal): New function.
2748 (variable_smob): Use var_equal as the discriminator for variables.
2750 * throw.c (s_throw): Remove extraneous declaration.
2752 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
2753 * eval.c: Add necessary CPP cruft to support that.
2754 * configure, Makefile.in, scmconfig.h.in: regenerated.
2756 Change from Thomas Morgan:
2757 * procprop.c (scm_procedure_properties): Convert the Scheme
2758 boolean returned by scm_procedure_p into a C boolean before using
2759 it as a condition for SCM_ASSERT.
2760 (scm_procedure_property): Likewise.
2762 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
2763 indications of Unixness.
2766 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2768 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
2770 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2772 * read.c (scm_lreadr): use scm_misc_error to improve one of the
2773 "unknown # object" error messages.
2775 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
2776 (scm_i_index) and declare it static. Add a 'direction' argument
2777 to indicate what way the search should go.
2778 (scm_i_index): throw out-of-range error instead of wrong-type-arg
2780 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
2781 strop.h: remove scm_i_index, scm_i_rindex prototypes.
2783 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2785 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
2787 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
2788 to avoid clash with various scsh forks.
2790 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
2792 The following two changes (ramap.c, throw.c) are motivated by the
2793 apparent unportability of forward declarations of static arrays of
2794 the form `static foo bar[];'.
2796 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
2797 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
2799 * throw.c (scm_throw): Moved above scm_ithrow.
2801 * options.h: Removed the extern declarations of scm_yes_sym and
2802 scm_no_sym since these are static.
2804 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2806 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
2808 * Makefile.am: remove AWK=@AWK@.
2809 Add a rule for generating errnos.list.
2810 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
2812 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
2813 don't extract errnos, just set a variable (avoids the
2814 need to recompile error.c just because configure is run.)
2816 * unif.h: update prototypes.
2817 * unif.c (scm_uniform_array_read,write): change the offset and
2818 length arguments to start and end, for consistency.
2820 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
2822 * ioext.h: update prototypes.
2823 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
2824 scm_read_line_x, it's a more general procedure using an
2825 interface from scsh. read-line and read-line! are now defined
2827 Note that the new read-line trims the terminator
2828 by default, previously it was appended to the returned string. An
2829 optional argument specifies how to process the terminator (scsh
2830 compatible). For the old behaviour: (read-line port 'concat).
2831 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
2832 returns a pair, but is converted to multiple values if the scsh
2835 socket.h: update prototypes.
2836 * socket.c (scm_recvfrom): for consistency with other procedures,
2837 take start and end as separate optional arguments.
2838 (scm_recv, scm_recvfrom): don't allow the second argument
2839 to be a size, only a buffer. Change the scheme names to
2840 recv! and recvfrom!. Don't return the buffer.
2842 * ioext.h, posix.h: move prototypes too.
2843 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
2844 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
2845 "read.h" and "unif.h".
2846 * ioext.c: include "chars.h"
2848 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
2850 * dynl.c: The dynamic linking and module registration functions
2851 are now defined even when dynamic linking is not available for the
2852 host system. Some of their functionality can be done without
2853 dynamic linking; when it's really needed, they throw errors.
2855 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
2857 * configure.in: Only define DYNAMIC_LINKING when one of the system
2858 dependent functions is detected.
2859 * dynl.c (scm_dynamic_func): New function to get the address of a
2860 function in a dynamic object.
2861 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
2862 produced by scm_dynamic_func as the thing to call.
2864 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
2866 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
2867 (scm_register_module_xxx, scm_registered_modules,
2868 scm_clear_registered_modules): New functions.
2870 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
2872 * symbols.c (scm_sysintern): Renamed to
2873 scm_sysintern_no_module_lookup.
2874 (scm_sysintern): New function to take the place of the old
2875 scm_sysintern. It uses the current toplevel lookup closure to give
2876 the symbol its value. This is a temporary hack to put packages
2877 like gtcltk into their own module.
2878 (scm_can_use_top_level_lookup_closure_var): New variable to tell
2879 us whether `scm_top_level_lookup_closure_var' has been initialized
2881 * eval.c (scm_init_eval): Set it.
2883 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
2885 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
2886 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
2888 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
2890 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
2891 scm_sys_dup): deleted: FD capability will be added to other
2893 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
2894 scm_fd_free, fd_smob, scm_intern_fd.
2895 (scm_open): renamed from scm_sys_open. Return a port instead of
2896 an FD object. Make the mode argument optional.
2897 (scm_sys_create): deleted, it's just a special case of open.
2898 (scm_init_filesys): move interning of constants O_CREAT etc.,
2899 here (were previously using SCM_CONST_LONG macro).
2900 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
2902 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
2903 include "fports.h" and <stdio.h>
2904 (scm_stat, scm_select): don't support FD objects.
2906 * error.h: adjust scm_syserror_msg prototype.
2907 * error.c (scm_syserror_msg): take an extra argument for errno.
2908 Using the global value didn't always work, since it could be
2909 reset by procedure calls in the message or args arguments.
2911 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
2912 I don't understand why the check was there (and what about the
2915 * strop.c (scm_string_copy): allow shared substrings to be copied.
2917 * unif.h: corresponding change to prototypes.
2918 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
2919 recognize two new optional arguments: offset and length. Allow
2920 the port argument to be an integer (file descriptor, for scsh).
2921 Include <unistd.h> for "read" prototype.
2923 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2925 * socket.c: don't include filesys.h.
2927 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
2929 * Makefile.am: add AWK=@AWK@ (?)
2931 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
2933 Add a rule to generate errnos.c from errnos.
2934 * error.c (scm_init_error): include errnos.c.
2935 * errnos_cnvt.awk: new file, converts the list of errno codes to
2937 * errnos_get.c: new file.
2938 * errnos.default: new file, contains errnos to try if they can't
2939 be extracted from errno.h.
2940 * configure.in: if using GCC, try and extract errno codes from
2944 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
2946 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
2947 * Makefile.am: Made libguile into a libtool library.
2948 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
2949 Set libtool_libs to indicate that libguile is a libtool library.
2950 See guile/ChangeLog for details.
2951 * .cvsignore: ignore "*.lo", the libtool library objects.
2953 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2955 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
2956 use htons in getservbyport argument.
2958 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2960 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
2961 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
2964 * objprop.c (scm_object_property): No need to take the CDR of the
2965 value returned by scm_object_properties, since Aug 20 change.
2967 * configure.in: When checking for struct linger, #include
2968 <sys/types.h> as well as <sys/socket.h>. I've never known
2969 <sys/types.h> to cause any portability problems, and Solaris's
2970 <sys/socket.h> needs it.
2971 * configure: Rebuilt.
2973 I think the Sun compiler has chosen a perverse way to interpret
2974 ANSI declarations combined with K&R definitions. We'll
2975 appease it a little bit. But when it invades France, we fight.
2976 * print.c (scm_iprlist): Change 'tlr' argument to an int.
2977 * print.h (scm_iprlist): Here too.
2978 * numbers.c (scm_divbigdig): Change definition to match
2979 declaration in numbers.h.
2980 * unif.c (scm_makflo): Change definition to match declaration in
2983 * init.c (scm_boot_guile): Don't return the value of
2984 scm_boot_guile_1. This function doesn't return a value;
2985 scm_boot_guile_1 doesn't return a value (or return at all).
2987 * eval.c (unmemocopy): Add a semicolon to appease the Sun
2990 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
2991 compile. I have a feeling this function is a bad idea anyway ---
2992 one should always test for features, not systems.
2994 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
2995 semicolons. Only pure luck kept this from being noticed earlier.
2997 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
2999 * socket.c (scm_recvfrom): Added missing semicolon.
3001 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3003 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3004 the buffer and start and end positions for scsh networking
3007 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3009 * configure.in: Revert previous change to this file; the problem
3010 is due to transient automake weirdness.
3011 * configure: Rebuilt.
3013 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3014 PLUGIN/guile.libs. configure generates the latter from the former.
3015 * Makefile.in: Rebuilt.
3017 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3018 need this if we install scripts, like guile-snarf.
3019 * configure: Rebuilt.
3021 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3023 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3025 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3027 * socket.c (scm_addr_vector): fix faulty scm_listify.
3029 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3031 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3032 style block comment is no longer considered an error.
3034 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3036 * PLUGIN/guile.libs.in: New file.
3037 * PLUGIN/guile.libs: Removed from repository.
3038 * configure.in: Create PLUGIN/guile.libs from
3039 PLUGIN/guile.libs.in. This is for including additonal libraries
3040 needed for dynamic linking.
3041 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3042 instead of PLUGIN/guile.libs.
3044 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3046 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3048 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3049 occurrences of the given element from the list, not just the
3050 first. This is how the Emacs Lisp functions behave, how the
3051 analogous Common Lisp functions behave, and (I believe) how the
3052 older Maclisp functions worked. I realize that this change may
3053 break code, but it seemed better to break it before the Guile
3056 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3057 Their prototypes were already present in gc.h, but they weren't
3059 (scm_init_storage): Initialize scm_protects.
3060 * root.c (scm_protects): New element of scm_sys_protects.
3062 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3064 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3066 * libguile.h: Added #include "libguile/net_db.h".
3068 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3069 30 change. That file is only meant for communication between the
3070 configuration process and load.c. If code linked against libguile
3071 wants to get at the paths mentioned in libpath.h, it can call
3072 functions declared in load.h.
3074 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3076 * libguile.h: Removed #include "libguile/fdsocket.h"
3078 * net_db.c: Added #include <sys/socket.h>.
3080 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3082 * filesys.c (scm_input_waiting_p): use select in preference to
3083 FIONREAD, since the latter doesn't detect EOF.
3084 Throw error if neither select nor FIONREAD available.
3086 * socket.c (scm_connect): take a port, not a fd object.
3087 (scm_fill_sockaddr): throw an error if fam is not recognised.
3088 (scm_bind): use scm_fill_sockaddr.
3089 (scm_listen): take a port, not a fd object.
3090 (scm_accept): take and return a port. return #f in the car if
3091 address can't be got
3092 (scm_sock_fd_to_port): new procedure.
3093 (scm_socket): use scm_sock_fd_to_port.
3094 (scm_addr_vector): throw error if unrecognised address type.
3095 take an extra argument with the calling procedure name.
3096 (scm_getsockname): take a port. return #f if address can't be got.
3097 (scm_getpeername): take a port. return #f if address can't be got.
3098 (scm_recvfrom): take a port. return #f for address component if can't
3100 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3101 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3103 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3105 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3106 use separate data pointers, to allow them to be designed
3107 independently and reused.
3108 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3109 Renamed from catch_body, catch_handler, and uncaught_throw; made
3111 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3113 (scm_catch): Use the above.
3114 (scm_throw): Don't bother printing a message for an uncaught
3115 throw; we establish a default handler in init.
3116 * throw.h (scm_internal_catch): Prototype updated.
3117 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3119 (struct scm_body_thunk_data): New structure, used as data
3120 argument to scm_body_thunk.
3121 * init.c (struct main_func_closure): New structure, packaging up
3122 the data to pass to the user's main function.
3123 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3124 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3125 scm_internal_catch to establish a catch-all handler, using
3126 scm_handle_by_message. This replaces the special-case code in
3128 (invoke_main_func): Body function for scm_internal_catch; invoke
3129 the user's main function, using the main_func_closure pointer to
3130 decide what to pass it.
3131 * root.c (struct cwdr_body_data): Remove handler_proc member.
3132 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3133 (cwdr_handler): Removed.
3135 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3137 * socket.h (SCM_P): update bind prototype.
3138 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3139 include "feature.h".
3140 (scm_socket): return a port, not a file descriptor object.
3141 include "fports.h" and <unistd.h>
3142 (scm_bind): take a port, not a file descriptor object.
3143 take an extra argument for address args.
3145 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3146 INADDR_NONE, INADDR_LOOPBACK.
3148 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3150 * init.c: include net_db.h and not fdsocket.h.
3151 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3153 * Makefile.am: corresponding changes.
3154 * socket.h: renamed from fdsocket.h, fix names.
3155 * net_db.h: renamed from socket.h, fix names.
3156 * socket.c: renamed from fdsocket.c.
3157 remove _sys from procedure names.
3158 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3159 add "socket" to features list.
3160 * net_db.c: renamed from socket.c.
3161 remove _sys from procedure names.
3162 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3163 add "net-db" to features list.
3164 include "net_db.h". don't include <sys/socket.h> or
3167 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3169 * tags.h (scm_tags): Removed comma at end of last enumerator.
3171 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3173 Don't use GCC extensions to allocate space for debugging frames.
3174 (Here he goes again! Why do we put up with this?!)
3175 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3176 an scm_debug_info structure, not an in-line array of them. Add
3177 'info' member, to say how many vect elements we've used, for eval
3179 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3180 a new variable debug_info_end to mark the end of vect, instead of
3181 the address of the 'info' pointer itself.
3182 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3183 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3184 (SCM_APPLY): Explicitly allocate space for debug.vect.
3185 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3186 * stacks.c: Adjusted for new debug frame structure.
3187 (RELOC_INFO, RELOC_FRAME): New macros.
3188 (stack_depth, read_frames): Use them, and new scm_debug_frame
3189 element 'info', instead of magically knowing that eval frames have
3190 an info pointer sitting after vect.
3191 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3193 (scm_init_stacks): Formatting tweaks.
3195 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3197 Give GCC more control flow information, so it can be sure that
3198 variables aren't used uninitialized.
3199 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3200 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3201 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3202 scm_misc_error): Tell GCC that these functions never return.
3203 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3204 out the field type, call abort if SCM_ASSERT returns, to placate
3206 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3207 scm_wta ever returns. We can't handle this case anyway, and this
3208 gives the optimizer more information.
3209 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3210 scm_wta ever returns.
3212 In some cases, the code is fine, but GCC isn't smart enough to
3213 figure that out; this usually happens when one variable is only
3214 initialized and used when a particular condition holds true, and
3215 we know that condition will never change within a given invocation
3216 of the function. In this case, we simply initialize the variables
3217 to placate the compiler, hopefully to a value which will cause a
3218 crash if it is ever actually used.
3219 * print.c (scm_iprin1): Initialize mw_pos.
3220 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3221 * throw.c (scm_ithrow): Initialize dynpair.
3222 * unif.c (scm_uniform_vector_ref): Initialize cra.
3223 * struct.c (init_struct): Initialize prot.
3224 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3226 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3227 if EXPR contains no expressions.
3229 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3231 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3232 cause an infinite loop (???). So much for the algebraic
3233 equivalency of variable-sized arrays and alloca...
3235 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3237 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3238 a SCM boolean, not a C boolean.
3240 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3242 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3243 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3244 rules for raising scm_mtrigger. Previously, unfortunate but not
3245 unlikely circumstances could result in almost constant invokation
3246 of the gc. Now, this situations should be less likely, but they
3247 are not prevented completely.
3249 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3251 * numbers.c (scm_fuck): Procedure removed; looks like old test
3253 * numbers.h: Prototype removed.
3255 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3257 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3258 array to a pointer, to match my Nov 21 change in eval.c.
3260 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3262 * libguile.h: Added #include "libguile/backtrace.h", #include
3263 "libguile/stacks.h".
3265 * strings.c (scm_string scm_make_string scm_string_ref
3266 scm_string_set_x scm_string_equal_p scm_string_append):
3267 Bugfix according to scm patch from Aubrey Jaffer:
3268 Corrected long-standing
3269 (not (eqv? (integer->char 128)
3270 (string-ref (make-string 1 (integer->char 128)) 0)))
3271 bug found by John Kozak <jk@noontide.demon.co.uk>.
3273 * strports.c, strports.h: Make scm_eval_0str return the value of
3274 the last expression evaluated (previously, it returned void).
3276 * strports.c, strports.h: New function: scm_read_0str. Does what
3279 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3281 * simpos.c (scm_getenv): return #f if string can't be found in the
3282 environment instead of throwing an exception, for compatibility
3283 with numerous other systems.
3285 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3287 * Makefile.am (.c.x): Use guile-snarf.
3288 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
3290 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
3292 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3294 * backtrace.c (scm_display_error_message): Made non-static, and
3295 renamed from display_error_message.
3296 * backtrace.h (scm_display_error_message): Added extern decl.
3297 * throw.c (uncaught_throw): Use it to display the error message.
3299 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
3301 * inet_aton.c: Use #if 0, not #ifdef 0.
3303 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
3305 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
3306 to convert the returned value.
3307 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
3308 the offset argument.
3310 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3312 Add new interface to catch/throw, usable from C as well as
3314 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
3315 (scm_internal_catch): New function, replaces...
3316 (scm_catch_apply): Deleted.
3317 * throw.c (scm_catch_apply): Deleted; replaced with a more general
3318 mechanism which is a bit more code, but can be used nicely from C
3319 and implement the Scheme semantics as well.
3320 (scm_internal_catch): This is the replacement; it's named after
3321 the analogous function in Emacs.
3322 (scm_catch): Reimplemented in terms of the above.
3323 (struct catch_body_data, catch_body, catch_handler): New
3324 functions, used by scm_catch.
3325 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
3326 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
3327 support for new cwdr.
3329 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
3332 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
3334 * acconfig.h: Added DYNAMIC_LINKING symbol.
3335 * configure.in: Add option and checks for dynamic linking.
3336 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
3337 dynl.h: New files for dynamic linking support.
3338 * Makefile.am (libguile_a_SOURCES):
3340 (modinclude_HEADERS): Added "dynl.h".
3341 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
3343 * init.c (scm_boot_guile_1): Call
3344 scm_init_dynamic_linking to initialize dynamic linking support.
3346 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
3348 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
3349 (as we Schemers say). It needs to be global, so that I can tweak
3350 it for the proper operation of unexec.
3351 (scm_boot_guile_1_live): New variable, see above.
3353 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
3355 * guile-snarf.sh: Removed.
3356 * PLUGIN/guile.libs: Added dependency for -lm.
3357 * acinclude.m4: Renamed from aclocal.m4.
3358 * PLUGIN/greet: Removed.
3359 * Makefile.am, aclocal.m4: New files.
3360 * configure.in: Updated for Automake.
3362 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
3364 * eval.c (scm_definedp): Use top_level_lookup_closure_var
3365 and not top_level_lookup_thunk_var.
3367 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
3369 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
3371 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
3373 * eval.c (scm_definedp): Incompatibly changed to be a builtin
3374 Scheme function, instead of syntax. Single argument is now a
3377 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3379 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
3380 scm_ra_divide): Properly terminate statements passed as arguments
3381 to IVDEP macros. (Thanks to Bernard Urban.)
3383 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
3384 with non-constant sizes. (Thanks to Bernard Urban.)
3386 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3388 It's an "eval closure", not an "eval thunk." A thunk is a
3389 function of no arguments.
3390 * root.h (struct scm_root_state): Renamed
3391 top_level_lookup_closure_var from top_level_lookup_thunk_var.
3392 (scm_top_level_lookup_closure_var): Renamed from
3393 scm_top_level_lookup_thunk_var.
3394 * root.c (mark_root): Uses changed.
3395 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
3396 * init.c (scm_start_stack): Uses changed.
3397 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
3398 Change scheme-visible name to *top-level-lookup-closure* from
3399 *top-level-lookup-thunk*.
3401 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
3403 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
3404 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
3406 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
3408 * gc.c (struct scm_heap_seg_data): Doc fixes.
3410 * gc.c (scm_gc_sweep): Empty all segments' freelists before
3411 sweeping. Then, prepend each segment's free cells to its
3412 freelist, rather than wiping out the old value. (Thanks to Marius
3415 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
3416 scm_check_freelist, scm_debug_newcell): New functions and
3417 variables, for debugging freelist problems.
3418 * pairs.h (SCM_NEWCELL): New debugging version added.
3419 * gc.h (scm_debug_newcell): Added extern declaration, used by
3420 debugging version of SCM_NEWCELL.
3422 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3424 On some systems <libc.h> conflicts with <unistd.h>, and should not
3425 be #included at all.
3426 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
3427 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
3428 * configure.in: Call it.
3429 * posix.c, filesys.c: Use its results to decide whether or not to
3431 * configure, scmconfig.h.in: Rebuilt with autoconf and
3434 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
3436 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
3437 pointer to the stdio stream before calling scm_setbuf0, so the
3438 latter will be able to retrieve it. I'm surprised this didn't
3439 segfault earlier. (Thanks to Christopher Lee.)
3441 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3443 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
3446 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3448 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
3449 number of stack narrowing specifier pairs. The first specifier in
3450 a pair controls inner border, the second the outer border. A
3451 number means cut that number of frames, a procedure object means
3452 cut until that object is found in operator position in a frame.
3454 * root.c (cwdr): Bugfix.
3456 * read.c: Recording of positions disabled by default.
3458 * procs.c (scm_closure_p): New function.
3460 * posix.c (scm_tmpnam): New function.
3462 * load.c: Added #include "throw.h".
3463 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
3466 * load.c, load.h (scm_read_and_eval_x): New function.
3468 * eval.c: Renamed debug option "deval" to "debug".
3470 (scm_eval_x): `eval!' is no longer accessible from the scheme
3471 level. Motivation: We can't allow operations which introduce
3472 glocs into the scheme level. Guile's type system can't handle
3473 these as data. Use `eval' or `read-and-eval!' as replacement.
3475 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
3476 SCM_CONSP since this is a macro!; Set vframe.prev to
3477 scm_last_debug_frame instead of 0. In this way we can look
3478 "above" the virtual start stack frame if we wish.
3479 (scm_debug_hang): New function: Useful for debugging Guile in
3480 certain tricky situations. Will probably be removed later...
3482 * debug.h: Changed semantics of debug option "backtrace". This
3483 option now only indicates whether we want automatic backtrace at
3486 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3488 * ports.c: #include "filesys.h"
3489 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
3491 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
3492 Motivation: This is system specific code which is related to file
3493 I/O. It also may use select. Added code by Gary Houston to
3494 detect presence of character in stdio buffers.
3496 * libguile.h: #include "libguile/libpath.h"
3498 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
3499 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
3500 SCM_SITE_DIR; Install libpath.h among the other include files.
3502 * load.c, load.h (scm_sys_package_data_dir): New function.
3504 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3506 * stacks.h: Bugfix: Don't use tail-array length field as stack
3507 length field! This screwed GC.
3509 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3511 * _scm.h: Added #ifndef around definition of macros min and max.
3513 * __scm.h: Added hooks for threads to plugin to in ints protection
3514 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
3515 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
3516 the main code in these macros duplicated and spread over multiple
3517 files. Renamed SCM_THREADS_SWITCHING_CODE ->
3518 SCM_THREAD_SWITCHING_CODE.
3520 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
3522 * snarf.h: New file.
3523 * guile-snarf.sh: New file.
3524 * Makefile.in (inner_h_files): Added snarf.h
3525 (ancillary, install, uninstall, distclean): Added actions for
3527 (.c.x): Use guile-snarf.
3528 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
3529 (gen_c_files): Note that these depend on guile-snarf.
3530 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
3531 now in "snarf.h". Added #include "snarf.h" to get them.
3532 * libguile.h: Added #include "snarf.h".
3533 (Patches applied and tweaked by Jim Blandy.)
3535 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
3537 * socket.c: Use K&R style declaration for 'close'; the GNU coding
3538 standards suggest against providing prototypes for system
3539 functions. Thanks to Greg Troxel.
3541 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3543 * strports.c (scm_eval_0str): New function.
3544 #include "read.h", to get prototype for scm_read.
3545 * Makefile.in (strports.o): Update dependencies.
3546 * strports.h: New prototype.
3548 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
3549 scheme name from "int?" to "integer?". It seems to do the job.
3550 * numbers.h: Rename prototype too.
3551 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
3554 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
3555 scm_num_eq_p): Rename these according to R4RS conventions: call
3556 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
3557 to making libguile R4RS compliant without ice-9...
3559 * load.c (scm_sys_search_load_path): Search for files under all
3560 extensions listed in the %load-extensions variable. If FILENAME
3561 is absolute, return it unchanged, without searching the load path.
3562 (scm_loc_load_extensions): New variable, pointing to
3563 %load-extensions' value cell.
3564 (scm_init_load): Initialize it, and the value it points to.
3565 (scm_primitive_load_path): Improve error reporting.
3567 * load.c (scm_loc_load_hook): New variable, pointing to value cell
3568 of new Scheme variable %load-hook.
3569 (scm_primitive_load): Apply %load-hook to filename.
3571 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
3573 * configure.in: add tests for figuring out whether buffered data
3574 is available in a FILE structure, which is needed by char-ready.
3576 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
3579 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
3580 exceptions using misc_error instead of syserror. It seems a bit
3581 odd to throw an exception if a string can't be found in the
3582 environment, but it's consistent with open-file, stat etc.
3583 (simpos.h): remove sys_ from getenv.
3585 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
3586 occurs, throw an error instead of returning errno. Return value
3588 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
3590 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
3592 * filesys.c (scm_stat2scm): derive file type and permissions from
3593 the stat mode and append them to the returned vector.
3594 There isn't much overhead in doing this and it avoids the need to
3595 work with S_IRUSR et al. in Scheme.
3596 Define symbols scm_sym_regular etc.
3597 (scm_init_filesys): don't intern S_IRUSR etc.
3599 * load.c: change s_try_load and s_try_load_path to s_primitive_load
3600 and s_primitive_load_path.
3602 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
3604 * error.h: don't declare error symbols. prototype for scm_misc_error.
3606 * stackchk.c (scm_stack_overflow_key): defined here instead of in
3609 * error.c: use SCM_SYMBOL to set up error keys.
3610 scm_misc_error: new procedure.
3612 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3614 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
3615 between `#!' and `!#' is ignored.
3616 (skip_scsh_block_comment): New function.
3618 * feature.c (scm_set_program_arguments): New argument, FIRST.
3619 * feature.h: Update prototype.
3620 * init.c (scm_boot_guile_1): Pass new argument to
3621 scm_set_program_arguments.
3623 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3625 * init.c (scm_start_stack): Don't initialize scm_progargs here.
3626 (scm_boot_guile): Call scm_set_program_arguments here, later than
3627 the old initialization.
3629 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
3630 initialization procedure.
3631 - Delete in, out, err arguments; there are other perfectly good
3632 ways to override these when desired.
3633 - Delete result argument; this function shouldn't ever return.
3634 - Rename init_func argument to main_func, for less confusion.
3635 - Delete boot_cmd argument; main_func is more general.
3636 -Add 'closure' argument, to help people pass data to main_func
3637 without resorting to global variables.
3638 - Abort if reentered; don't bother returning an error code.
3639 - Call scm_init_standard_ports to set up the default/current
3640 standard ports; no need to pass them to scm_start_stack.
3641 - Remove code to evaluate the boot_cmd, and start the repl; let
3642 the user do something like that in main_func if they want.
3643 - Remove code to package up a return value; main_func can do any
3645 - Call exit (0), instead of returning.
3646 (scm_start_stack): Don't initialize the I/O ports here; that's
3647 weird. Delete in, out, err arguments. Move guts to
3648 scm_init_standard_ports, scm_stdio_to_port.
3649 (scm_init_standard_ports): New function, to set up current and
3650 default standard ports.
3651 (scm_start_stack, scm_restart_stack): Make these static.
3652 * init.h (scm_boot_guile): Adjust declaration.
3653 (scm_start_stack, scm_restart_stack): Remove externally
3654 visible declarations for these.
3655 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
3657 * fports.c (scm_stdio_to_port): New function. Its guts used to be
3658 written out several times in scm_start_stack.
3659 * fports.h: New declaration for the above.
3661 * feature.c (scm_set_program_arguments): New function.
3662 * feature.h: New declaration for the above.
3664 * ports.c: Formatting tweak.
3666 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
3668 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
3669 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
3670 for obtaining the address of a car or cdr field. Motivation:
3671 &SCM_CXR make assumptions about the internal structure of the
3674 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
3675 Motivation: see SCM_CXRLOC.
3677 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
3678 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
3679 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
3680 Motivation: Safer use. Some other macros are defined in terms of
3681 these operations. If these are defined using the SCM_SETCXR
3682 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
3683 to inefficiency and an <e1> with side-effects could potentially
3684 break. Also, these particular operations are heavily utilized in
3685 the garbage collector. In unoptimized code there will be a
3688 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
3689 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
3690 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
3691 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
3692 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
3693 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
3694 vports.c: Cleaned up use of pairs: Don't make any special
3695 assumptions about the internal structure of selectors and
3696 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
3697 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
3698 (Among other things, this change makes it easier to build Guile
3699 with certain compilers which have problems with casted lvalues.)
3701 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3703 * stacks.c: Improve selection of relevant stack frames when making
3704 a stack object. Introduce one level of indirection in the stack
3705 object to make it possible to "narrow" to a certain region of the
3706 stack. This facilitates making use of more clever algorithms (not
3707 implemented) for selecting relevant frames and gives a cleaner
3708 design since selection of frames can be done independently of
3709 extraction of frames from the real stack.
3710 (scm_stack_id): Also take #t as argument which means look at
3713 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
3714 Turn n_tail into an integer directly representing current number
3715 of frames in stack. Add field tail.
3717 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
3719 * debug.c (scm_make_memoized): Made it available at scheme level.
3720 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
3721 SCM_NIMP before applying heavier predicates in argument checking.
3722 (scm_local_eval): Also take memoized object as argument.
3724 * backtrace.c (scm_display_error): Just a safety measure: Stacks
3725 aren't created with zero length, but should such a strange
3726 creature suddenly turn up...
3728 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
3730 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
3731 `del', for the sake of C++ compilers. (Patch applied by JimB.)
3733 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
3735 * variable.c (scm_make_variable): Make the name hint optional, as
3737 (anonymous_variable_sym): Renamed from variable_sym. All uses
3740 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
3741 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
3742 of scm_primitive_load_path was also changed to
3743 "primitive-load-path", from "%try-load-path". Callers changed.
3744 We'd like to respect the convention that a function named
3745 "try-mumble" should behave just like the function called "mumble",
3746 but return #f instead of signalling some error.
3747 * load.h: Rename prototypes.
3749 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3751 * print.c (make_print_state, grow_print_state), print.h: Modified
3752 the print state representation: Don't use a tail array for
3753 recording of circular references. Resizing of the print state
3754 structure invalidates the print state pointer. To avoid passing
3755 around an indirect print state reference to all printing
3756 functions, we instead let the print state reference a resizable
3759 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
3761 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
3762 Don't crash when passed an improper list terminated by a
3763 non-immediate value.
3765 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
3767 Allocate data for structures on an eight-byte boundary, as
3768 required by the tagging system.
3769 * struct.c (alloc_struct): New function.
3770 (scm_make_struct, scm_make_vtable_vtable): Call it.
3771 * struct.h (scm_struct_n_extra_words): Bump to 3.
3772 (scm_struct_i_ptr): New "field".
3773 * gc.c (scm_gc_sweep): When we need to free the data, use the
3774 information stored by alloc_struct to find the beginning of the
3775 block allocated to the structure, so we can free it.
3777 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3779 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
3782 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
3783 (scm_debug_info): New member: id.
3785 * stacks.c: Stacks are now represented as structs; Stacks have an
3786 id given to them by `start-stack'.
3787 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
3789 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
3790 Changed stack representation.
3792 * debug.c (scm_procedure_name): Try procedure property `name' for
3793 compiled closures aswell.
3795 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
3797 * eval.c: scm_i_name moved to gsubr.c
3798 (scm_m_define): Record names of all kinds of procedure
3799 objects. (Earlier, only closures were recorded.)
3801 * procprop.h: Added declaration of scm_i_name.
3803 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
3804 (scm_make_gsubr): Record names of compiled closures.
3806 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3808 * debug.c, debug.h: Removed obsolete code.
3810 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
3811 stacks.c: Renamed regs --> scm_contregs.
3813 * print.c (scm_free_print_state): Cleanup print state before
3814 returning it to pool. It is better to do it here than in
3815 scm_prin1 since scm_prin1 is called often.
3817 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
3818 s_set_source_property_x): Check that first argument is a pair or a
3821 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
3822 scm_i_line, scm_i_column and scm_i_breakpoint global.
3824 * init.c: Added #include "backtrace.h" and #include "stacks.h".
3825 (scm_boot_guile_1): Added calls to scm_init_backtrace and
3828 * debug.h: Added debug object smob declaration and macro
3831 * configure.in: Build with backtrace.o and stacks.o if debug
3834 * Makefile.in: Added entries for new files: backtrace.c,
3835 backtrace.h, stacks.c and stacks.h.
3837 * symbols.c (scm_sym2ovcell): Fixed documentation.
3839 * _scm.h (min, max): Added.
3841 * async.c: Moved `min' macro to _scm.h.
3843 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
3844 SCM_BACKTRACE_INDENT.
3846 * eval.c: Added new debug options `maxdepth' and `indent'.
3848 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
3850 * print.h: Added selector SCM_PRINT_STATE.
3852 * print.c: New functions: scm_make_print_state,
3853 scm_free_print_state.
3855 * print.h: Added declarations for scm_make_print_state,
3856 scm_free_print_state.
3858 * debug.c (scm_m_start_stack): New acro.
3860 * debug.h: Small cleanup.
3862 * init.c (scm_boot_guile_1): Moved scm_init_debug below

3890 More prototype-related changes from Marius Vollmer:
3891 * gdb_interface.h: Wrapped header file in #ifdef/#endif
3892 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
3893 * ports.h (ptobfuns): Added prototypes. This means some casting in
3895 * fports.c: Added casts for initializations, since the functions
3896 are defined to take FILE * as their stream argument, not SCM.
3897 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
3898 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
3899 to `char *str_data' to conform to prototype.
3901 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
3903 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
3905 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
3907 * stime.c, stime.h: use SCM_P method.
3909 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
3911 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
3912 be given at least two arguments. Insist that lst's last element
3913 be a list, but don't make any requirements of its predecessors.
3915 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
3917 * eval.c (scm_nconc2last): Revert last change; there seems to be
3918 other stuff going on here.
3920 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
3922 * eval.c (scm_nconc2last): Make sure that each element of lst
3923 (which is a list of argument lists, except for the tail) is a
3924 proper list, i.e., finite and terminated by '().
3926 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
3928 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
3931 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
3932 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
3935 * vectors.c (scm_make_vector): Fill vectors with the undefined
3936 value, to help make Guile Scheme code more portable to other
3939 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
3940 * symbols.h, tags.h: Doc fixes.
3942 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
3944 * async.c (scm_take_signal): Doc fixes.
3946 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
3948 * numbers.c (scm_divbigint): When the remainder is zero, we don't
3949 want to subtract it from the modulus; we just want to leave it
3952 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
3954 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
3957 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
3959 * throw.c (scm_catch_apply): Finished implementation of
3962 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
3964 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
3966 (scm_init_filesys): set "i/o-extensions" feature.
3969 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
3971 * Makefile.in (root.o): Correct dependencies.
3973 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
3975 * Makefile.in: Added dependency entry for root.o.
3977 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
3978 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
3980 * init.c (scm_start_stack): Set initial root continuation number
3983 * procs.c: New function: scm_thunk_p.
3985 * procs.h: Added declarations of scm_thunk_p.
3987 * root.c: Renamed `call-with-new-root' -->
3988 `call-with-dynamic-root'.
3989 (cwdr): Removed allocation of new root state. This should be done
3990 separately by use of scm_make_root.
3991 (scm_apply_with_dynamic_root): New function: Does what it
3992 sounds like. Needed when spawning threads.
3994 * root.h: Added member last_debug_frame to root state.
3995 Added #include "libguile/debug.h"
3997 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
3998 arguments. The motivation is that code in root.c needs catch
3999 functionality, and we want to avoid code duplication.
4000 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4001 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4002 handlers that run without popping the stack into the dynwind
4005 * throw.h: Added prototypes for scm_catch_apply and
4008 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4010 * root.h (scm_root, scm_set_root): Decouple thread support details
4011 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4012 SCM_SET_THREAD_LOCAL_DATA.
4014 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4015 and tortoise scanning loop.
4017 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4019 * Makefile.in: Rebuild dependencies.
4021 * libguile.h: #include "libguile/print.h" before "smob.h", since
4022 the latter uses the print_state structure.
4024 * throw.c (scm_ithrow): Use the correct variable when checking to
4025 see if a given element of scm_dynwinds is a valid catch.
4027 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4028 structure, abort; don't just silently ignore the garbage.
4030 * _scm.h: #include "print.h" here, since it seems to be used just
4032 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4033 strports.c, unif.h: Don't #include "print.h".
4035 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4037 * feature.h (scm_loc_features): Removed external declaration.
4038 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4040 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4042 * feature.c (scm_init_feature): Added threads feature (needs to be
4043 initialized here, since features doesn't exist when
4044 scm_init_threads is called).
4046 * libguile.h: Added #include "libguile/../threads/threads.h".
4047 (This is a kludge to get thread support working. This should be
4050 * configure.in, acconfig.h: Added flags for thread support.
4052 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4055 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4056 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4059 * _scm.h: Added conditional #include "threads.h"
4061 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4062 SCM_THREADS_SWITCHING_CODE.
4064 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4065 allocate the basic dynamic root object.
4066 (scm_boot_guile): Added call to scm_init_root.
4068 * root.c, root.h: Added root smob.
4069 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4070 functions: Implements dynamic roots mostly according to spec in
4071 SCM manual. Main difference is that the second argument is a
4072 throw handler rather than an error "thunk".
4074 * root.h: Added declaration of scm_init_root.
4076 * root.c: Added #include "genio.h", #include "smob.h", #include
4077 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4079 (scm_init_root): Added #include "root.x".
4081 * throw.c: Added #include "stackchk.h"
4082 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4083 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4084 can be used in scm_call_with_new_root; Added reenabling of stack
4085 checking when catching a throw.
4087 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4089 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4091 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4092 element is not found, as per R4RS.
4094 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4096 * list.c: Doc fixes throughout.
4098 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4100 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4101 declare the char * to be const. Avoids a warning in rgx.c.
4103 * ports.h: spelling fix.
4105 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4108 * load.c (scm_sys_try_load_path): throw an error if file not found
4109 (like it says it in NEWS).
4111 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4113 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4114 PROPS slot to '(), not #f; it's an empty alist.
4116 * throw.h, throw.c: Use SCM_P instead of #if hair.
4118 Remove special support for uncaught throws; see throw.c for
4120 * throw.c (uncaught_throw): New function.
4121 (scm_ithrow): Call uncaught_throw if we don't find a throw
4122 target; don't mess with scm_bad_throw_vcell.
4123 (scm_bad_throw_vcell): Variable deleted.
4124 (scm_init_throw): Don't initialize it.
4126 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4129 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4131 * numbers.c (scm_istr2int): If the number is short (as most
4132 numbers are), just call scm_small_istr2int to deal with it.
4133 (scm_small_istr2int): New function, created by un-#ifdefing the
4134 non-bignum version of scm_istr2int and renaming it.
4136 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4138 * load.c (scm_sys_try_load): don't check whether value returned
4139 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4140 Change the Scheme name from %try-load to primitive-load.
4142 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4143 Can avoid passing a message, allowing it to be derived in the
4144 error handler (e.g., if we want to throw to the key both from
4147 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4149 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4150 references now have a new appearance which is more compact and
4151 also gives a clue about what the target of the reference is.
4152 By setting parameters in the print state, more fancy printing can
4153 be achieved. This is used by the (not yet commited) backtrace
4156 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4158 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4161 * print.c: Added #include "struct.h". Removed function
4164 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4165 scm_iprin1. Removed prototype for scm_prlist.
4167 * arbiters.c (prinarb),
4168 async.c (print_async),
4169 debug.c (prindebugobj, prinmemoized),
4170 eval.c (prinprom, prinmacro),
4171 filesys.c (scm_fd_print, scm_dir_print),
4173 mallocs.c (prinmalloc),
4174 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4175 smob.h (scm_smobfuns),
4176 srcprop.c (prinsrcprops),
4178 unif.c, unif.h (scm_raprin1, rapr1),
4179 variable.c (prin_var): Changed argument `int writing' to
4180 `scm_print_state *pstate'.
4182 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4183 that it will be called before scm_init_print.
4185 * print.c (scm_prin1): Print states are now allocated when calling
4186 scm_prin1 and then passed around to all printing functions as an
4187 argument. A cache `print_state_pool' enables reuse of print
4189 (scm_make_print_state): New function.
4190 (scm_iprin1): Adaption to print states.
4191 (scm_iprlist): An initial "hare and tortoise" scan brings down
4192 time complexity to O (depth * N). (Better time complexity will be
4193 achieved when the printing code is completely rewritten.)
4195 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4197 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4198 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4199 it gets done whether or not the cache variable has a value.
4201 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4203 Distinguish #f and ().
4204 * __scm.h: #undef SICP.
4205 * pairs.h (SCM_EOL): Delete this definition, equating it with
4207 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4208 the value it used to have. Doc fixes, too.
4210 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4212 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4213 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4214 Lord's implementation of structs, allowing for tail arrays as
4215 described in the manual. Also fixed some bugs. (Both the interface
4216 and the implementation should be improved.)
4218 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4220 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4221 People who whish to see the source can do `(print-enable 'source)'.
4222 Removed #ifdef DEBUG_EXTENSIONS.
4224 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4226 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4227 integer (assuming for now accepting an integer is a good thing).
4229 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4230 %S will be used instead for write'ing arguments.
4232 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4233 asserts. fix a few other asserts.
4234 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4235 scm_uniform_vector_ref, scm_array_set_x,
4236 scm_dimensions_to_unform_array): change args in
4237 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4238 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4239 scm_substring_fill_x): likewise.
4240 gsubr.c (scm_gsubr_apply): likewise.
4241 eval.c (SCM_APPLY): likewise.
4243 * eval.c (4 places): replace scm_everr with lgh_error or
4246 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4247 scm_memory_error): new procedures.
4248 scm_everr: deleted. can use scm_wta, dropping first two args.
4249 scm_error: convert NULL subr to SCM_BOOL_F.
4251 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4254 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4257 * error.c, error.h: new error keys: scm_arg_type_key,
4258 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4260 scm_wta: reimplement using lgh_error instead of scm_everr.
4262 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4264 * gdbint.c: scm_lread now has one more argument.
4266 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4267 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4268 loading source from non-file ports, which, e. g., happens when
4269 using the Emacs interface).
4271 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4274 * read.c: Added code for recording of positions of source code
4275 expressions; New functions: recsexpr, scm_lreadrecparen;
4276 _scm_make_srcprops --> scm_make_srcprops
4277 (scm_flush_ws): Removed updating of positions counters. This work
4278 is already done by scm_gen_getc
4280 * read.h: Added prototype for scm_lreadrecparen
4282 * print.c: Added #include "alist.h"
4284 * eval.c: Added #include "hash.h"
4286 * eq.c: Added #include "ramap.h"
4288 * options.c: Documentation fixes.
4290 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
4291 (scm_init_srcprop): Adjusted size of initial source-whash. Name
4292 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
4293 --> scm_make_srcprops
4295 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
4296 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
4297 function calls in the definition of the whash access macros.
4299 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
4301 * init.c (scm_boot_guile): Add level of indirection to
4302 scm_boot_guile_1() to ensure that stack base pointer is properly
4303 initialized. There was no guarantee that variable i was the
4304 highest/lowest variable on stack (i.e. the call frame of
4305 scm_boot_guile was not completely protected from gc).
4307 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
4309 * ports.h (scm_port_table): put back file_name, it will be used to
4310 support debugging. Undo related changes in fports.c, ioext.c,
4313 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4315 * ports.h (scm_port_table): remove file_name member for now, it seems
4317 * fports.c (scm_open_file): don't set file_name in PTAB.
4318 (prinfport): don't use file_name in PTAB.
4319 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
4320 * ports.c (scm_add_to_port_table): don't intialize file_name.
4321 (scm_port_file_name): remove for now.
4322 * gc.c (scm_gc_mark): don't mark PTAB file_name.
4324 * fports.h (scm_mkfile): prototype deleted.
4325 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
4327 * debug.c, unif.c: use scm_out_of_range instead of
4328 wta for range errors (ASSERT still needs work).
4330 * error.c, error.h (scm_out_of_range): new procedure.
4332 * error.c, error.h (scm_out_of_range_key): new key.
4334 * posix.c (scm_sync): #else was missing.
4336 * error.c, error.h: append _key to names scm_num_overflow and
4339 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
4340 of consing an empty list.
4341 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
4342 of macros, saves code and string space.
4343 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
4344 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
4345 lower case. Rename scm_syserror_m to scm_syserror_msg.
4346 error.h: prototypes for new procedures.
4348 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
4350 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
4352 * error.c, error.h: setup scm_num_overflow key.
4354 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
4355 Remove definition of SCM_OVSCM_FLOW.
4357 * fports.c (scm_open_file): use SCM_SYSERROR_M.
4359 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
4360 explicit message and args.
4362 * error.c, error.h, __scm.h: change system_error_sym to
4365 * error.c (system_error_sym): remove leading %% from the Scheme name
4368 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
4370 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4372 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
4373 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
4374 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
4375 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
4376 renamed. (These were introduced by unsupervised name
4379 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4381 * print.c: Added code for detection of circular references during
4382 printing. (init_ref_stack, grow_ref_stack): New functions. Added
4383 a hook for printing of closures (accessible via print options).
4384 This leads to a split of calls to scm_iprin1 into two classes:
4385 elementary print operations (e. g. the code which prints a smob)
4386 still use scm_iprin1 while top level calls (like scm_display) use
4387 scm_prin1. scm_prin1 begins by clearing the data structure used
4388 to record reference information.
4390 * print.h: Added declarations of scm_prin1 and scm_prlist.
4392 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
4394 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
4396 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
4398 * error.c (err_head): scm_iprin1 --> scm_prin1
4400 * debug.c: Adjusted header comment.
4404 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4406 * strerror.c: Doc fix.
4408 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4410 * gdbint.c (gdb_read): Now possible to run during GC.
4411 (unmark_port, remark_port): New functions.
4413 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
4415 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
4416 of allocating a new string object. Also, increase size by
4417 the factor 2 instead of 1.5.
4419 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
4421 * __scm.h (SCM_P): Corrected to run under traditional C.
4423 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
4426 * async.c: Calls to scm_sysintern corrected.
4428 * async.h (scm_async_clock): Redundant declaration removed.
4430 * continuations.c (scm_dynthrow): Redundant declaration removed.
4432 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
4433 Definition typos corrected.
4435 * debug.h: Missing declarations of functions in debug.c added
4438 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
4439 Missing declarations to functions in eval.c added.
4441 * filesys.c: Possibly uninitialized variable rv.
4443 * gc.h (scm_object_addr, scm_unhash_name): Missing
4444 declarations of functions defined in gc.c added.
4446 * genio.c: Possible typos str_data -> wstr_data. ???
4448 * genio.c: Possibly unintended shadowing of local variable
4449 `int c' (gotos out of scope of inner `c'). ???
4451 * init.c: Uninitialized `SCM last' may be used.
4453 * ioext.h: (scm_sys_isatty_p): Typo.
4455 * list.h (scm_list_head): Missing prototype for function in
4458 * numbers.c (scm_two_doubles): Changed from extern to static
4459 (is used only within numbers.c).
4461 * numbers.h: Repeated declarations removed.
4463 * ports.h (scm_close_all_ports_except): Declaration for the
4464 function defined in ports.c added.
4466 * posix.h: Missing declarations added.
4468 * procs.h (scm_make_subr_opt): Missing declaration added.
4470 * socket.h (scm_sys_gethost): Missing declaration added.
4472 * socket.h: Redundant declarations removed (they are in fdsocket.h).
4474 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
4475 Missing declarations added.
4477 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
4479 * struct.c: Uninitialized variable `SCM answer' may be used.
4481 * unif.c (l2ra): Declaration prototype.
4483 * unif.c (scm_array_equal_p): Dummy definition removed (it is
4484 defined in ramap.c).
4486 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
4487 Redundant declarations removed (they are in ramap.h).
4489 * variable.h (scm_make_udvariable,
4490 scm_make_undefined_variable): Declaration corrected to
4491 correspond variable.c.
4493 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
4494 Missing declarations added.
4496 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
4498 * Makefile.in (distclean): Don't forget to delete fd.h.
4500 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4502 * fd.h.in, tags.h: Trivial cleanups.
4504 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
4505 marksweep.h just declared functions from gc.c.
4506 * gc.h, libguile.h: Don't #include "marksweep.h".
4507 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4508 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
4509 dependencies updated.
4511 * libguile.h: Don't #include "files.h"; it's been deleted.
4513 * files.c (scm_sys_delete_file): Moved to filesys.c.
4514 File is now empty; deleted.
4516 * filesys.c: scm_sys_delete_file is now here. Remove
4517 #if's; they seem to rely on remnants of an old portability
4518 regimen. If the problems come up again, solve them properly,
4519 using autoconf. Specifically: Don't test M_SYSV, and #define
4520 remove to be unlink if it's #defined; don't use remove just
4521 because HAVE_STDC_HEADERS is #defined.
4522 * filesys.h: Add declarations for scm_sys_delete_file.
4523 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4524 files.o, files.h, files.c, and files.x.
4525 * init.c: Don't #include "files.h", and don't call scm_init_files.
4527 Use SCM_P instead of PROTO; the latter intrudes on the user's
4529 * params.h: Deleted; definition of SCM_P moved to...
4530 * __scm.h: ... here, where it replaces PROTO macro.
4531 * libguile.h, smob.h: Don't #include "params.h".
4532 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
4533 smob.h: Fix prototypes accordingly.
4534 * Makefile.in: Update dependencies.
4535 (inner_h_files): Remove params.h.
4537 * gc.c: #include "gc.h"; every module should include its header,
4538 to let the compiler cross-check the declarations against the
4541 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
4542 simpos.h: #include "libguile/__scm.h".
4544 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
4546 * init.c: Don't forget to #include smob.h and init.h.
4547 * Makefile.in: Dependencies updated.
4549 * smob.h: Use PROTO instead of #if __STDC__.
4551 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
4553 * __scm.h: Doc fixes.
4555 * __scm.h, libguile.h: Use "quotes" in the #includes, not
4556 <angles>; this allows `make depends' to work properly.
4558 * libguile.h: #include smob.h and pairs.h before the others; they
4559 define typedefs used by other headers.
4561 C files should #include only the header files they need, not
4562 libguile.h (which #includes all the header files); the pointless
4563 recompilation was wasting my time.
4564 * Makefile.in (all .o dependency lists): Regenerated.
4565 * libguile.h: Don't try to get a definition for size_t here...
4566 * __scm.h: Do it here.
4567 * _scm.h: Since this is the internal libguile header, put things
4568 here that all (or a majority) of the libguile files will want.
4569 Don't #include <libguile.h> here; that generates dependencies on
4570 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
4571 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
4572 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

4669 * weaks.c: Get "weaks.h".
4671 * stackchk.h: #include "libguile/debug.h",
4673 * print.h, read.h: #include "options.h", since everyone who uses
4674 either of these files will need that.
4676 * smob.h: #include "ports.h", "genio.h", and "print.h", since
4677 anyone who uses this file will need them to define the smob
4678 printing functions. Also, get markers.h, since people will need
4679 to #define the mark functions.
4681 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
4682 * ports.h: ... to here.
4684 * ports.h (scm_port_table_size): Explicitly give type as 'int';
4685 don't rely on archaic C default type rules.
4687 * fports.h: #include "libguile/ports.h", since you need that in
4688 order to parse this.
4690 * genio.h: #include "libguile/print.h", because you need that to
4691 parse this; don't bother #including "ports.h", since print.h gets
4694 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
4696 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
4697 this; it's now a reference to an element of *scm_root.
4699 * debug.h: Don't #include "options.h"; the compiler won't be able
4700 to find that once the headers are installed; instead, #include
4701 "libguile/options.h".
4702 * gc.h: Same, with marksweep.h.
4703 * mbstrings.h: Same, with symbols.h.
4704 * scmhob.h: Same, with _scm.h.
4705 * smob.h: Same, with params.h.
4707 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
4708 C files; there's no need for this, and it forces recompilations
4711 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
4713 * error.c (scm_error): declare scm_error_callback.
4715 * error.h: prototype for scm_error_callback.
4717 * __scm.h: define lgh_error.
4718 (SCM_SYSERROR): redefine using lgh_error.
4720 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
4722 * error.c (scm_error): new procedure.
4724 * error.h: prototype for scm_error.
4726 * Makefile.in (install): install scmconfig.h from the current
4727 directory, not $(srcdir).
4729 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
4731 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
4732 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
4733 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

4739 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
4740 vports.h, weaks.h: #include "libguile/__scm.h", not
4741 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
4742 dependencies are within libguile properly.
4744 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
4746 * Makefile.in (.c.x): Simplify; there's no need to run this rule
4747 when scmconfig.h doesn't exist.
4749 * load.c (scm_sys_try_load): Correct spelling.
4751 * feature.c (scm_loc_features): Make this static.
4753 * Makefile.in (libpath.h): Omit trailing slash from path. We
4754 shouldn't require it of users, so why put it here?
4756 Move code to initialize and search %load-path from ice-9 to C
4757 code, so we can use the load-path to find the ice-9 boot code;
4758 this makes it easier to run Guile without installing it. See
4759 corresponding changes in guile/Makefile.in.
4760 * feature.c: Move stuff concerned with the load path to load.c.
4761 (scm_compiled_library_path): Deleted.
4762 Don't #include libpath.h here.
4763 * feature.h: Don't mention scm_compiled_library_path.
4764 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
4765 <sys/stat.h>, and <unistd.h> (if present).
4766 (R_OK): #define if the system hasn't deigned to.
4767 (scm_loc_load_path): New variable.
4768 (scm_init_load_path, scm_sys_search_load_path,
4769 scm_sys_try_load_path): New functions.
4770 (scm_init_load): Initialize scm_loc_load_path to point to the
4771 value cell of the Scheme %load-path variable.
4772 * load.h: Add declarations for scm_sys_search_load_path,
4773 scm_sys_try_load_path.
4774 * init.c: Call scm_init_load_path.
4775 * Makefile.in (feature.o, load.o): Dependencies updated.
4777 * load.c, load.h: Rewrite using PROTO macro.
4779 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4781 * gc.c (scm_cellp): New function: C predicate to determine if an
4782 SCM value can be regarded as a pointer to a cell on the heap.
4784 * gc.h: Added declaration of scm_cellp.
4786 * gdb_interface.h: New file: The GDB interface header from the GDB
4789 * gdbint.c: New file: GDB interface.
4791 * gdbint.h: New file: GDB interface.
4793 * libguile.h: Added #include <libguile/gdbint.h>.
4795 * init.c (scm_boot_guile): Added scm_init_gdbint.
4797 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
4798 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
4799 found if object files and source are kept separate).
4801 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
4803 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
4805 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
4807 * configure.in: Don't substitute the values of TCL_SRC_DIR and
4808 TK_SRC_DIR; they're not relevant any more.
4810 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
4811 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
4813 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
4815 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
4816 search path, so we can find the <libguile/MUMBLE.h> headers.
4818 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
4820 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
4821 implicit in the .c.o rule.
4822 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
4825 Put the library path in a header file, instead of passing it on
4826 the command line in every compilation.
4827 * Makefile.in (libpath.h): New target.
4828 (feature.o): Depend on libpath.h.
4829 (clean): Delete libpath.h.
4830 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
4831 * feature.c: ... #include "libpath.h" here.
4832 * .cvsignore: Ignore libpath.h.
4834 Don't install the unwashed masses of Guile header files in the
4835 main #include path; put most of them in a subdirectory called
4836 'libguile'. This avoids naming conflicts between Guile header
4837 files and system header files (of which there were a few).
4838 * Makefile.in (pkgincludedir): Deleted.
4839 (innerincludedir): New variable; this and $(includedir) are enough.
4840 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
4841 (installed_h_files): Divide this up. Now this variable lists
4842 those header files which should go into $(includedir) (i.e. appear
4843 directly in the #include path), and ...
4844 (inner_h_files): ... this new variable says which files appear in
4845 a subdirectory, and are referred to as <libguile/mumble.h>.
4846 (h_files): List them both.
4847 (install): Create innerincludedir, not pkgincludedir. Put
4848 the installed_h_files and inner_h_files in their proper places.
4849 (uninstall): Corresponding changes.
4850 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
4851 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
4852 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
4853 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
4854 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
4855 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
4856 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
4857 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
4858 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
4859 vports.h, weaks.h: Find __scm.h in its new location.
4860 * __scm.h: Find scmconfig.h and tags.h in their new locations
4861 (they're both "inner" files).
4863 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
4865 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
4867 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4869 * posix.c: Doc fixes.
4871 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
4873 * socket.c: Don't include a prototype for inet_aton; just use a
4874 K&R style declaration, to avoid warnings but minimize the chance
4875 of conflicts with the system.
4877 On NextStep, <utime.h> doesn't define struct utime, unless we
4878 #define _POSIX_SOURCE before #including it.
4879 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
4880 * acconfig.h: New comment text for above CPP symbol.
4881 * configure.in: Call it.
4882 * posix.c: #define _POSIX_SOURCE if it seems necessary.
4884 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
4886 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
4887 testing for __EMX__.
4889 * posix.c: #include <libc.h>, if it exists.
4891 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
4892 don't even know if the latter exists.
4894 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
4895 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
4896 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
4898 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
4900 (scm_init_posix): Use them when initializing the Scheme constants
4903 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4905 * Makefile.in (libdir, includedir, bindir): Use the
4906 autoconf-supplied values, instead of deriving them ourselves.
4907 (pkgincludedir, datadir, pkgdatadir): New variables.
4908 (install, uninstall): Put the header files in a special
4909 subdirectory, not in the main search path.
4911 * Makefile.in (ALL_CFLAGS): Provide the proper value for
4912 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
4914 * Makefile.in (IMPLPATH): Deleted; never used.
4916 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
4917 on the Tcl/Tk source any more.
4918 (INCLUDE_CFLAGS): Remove references to the above.
4920 * Makefile.in (version.o): Corrected dependencies.
4922 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
4924 * libguile.h: #include "version.h"
4926 * init.c (scm_boot_guile): Call scm_init_version.
4927 * gscm.c (gscm_run_scm): Call scm_init_version.
4929 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
4930 GUILE_VERSION): AC_DEFINE these.
4931 (acconfig.h): #undef the above symbols.
4933 * Makefile.in (libobjs): Add version.o.
4934 (installed_h_files): Add version.h.
4935 (c_files): Add version.c.
4936 (gen_c_files): Add version.x.
4937 (version.o): New rule.
4938 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
4939 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
4940 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
4941 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
4942 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
4943 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
4944 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
4945 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
4946 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
4947 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
4948 weaks.o): Add version.h to dependency lists.
4949 (markers.o): Remove duplicate rule.
4951 * version.h: New file.
4953 * version.c: New file.
4955 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4957 * symbols.c (scm_strhash): scm_downcase is now a function, not an
4958 array; use it appropriately. Since GCC is quite happy to
4959 subscript functions, it never warned us about this; we should use
4960 -Wpointer-arith in the future. I guess we never tested
4963 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
4965 * socket.c: Doc and copyright fixes.
4967 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4969 * debug.c: Fixed and improved gdb support.
4971 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4973 * socket.c: Added declaration of inet_aton to avoid compiler
4974 warning. (Hope this solution is correct.)
4976 * stime.c: Added declaration of ftime. (This is missing in
4979 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
4981 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
4983 * Makefile.in (c_files): add strerror.c.
4985 * strerror.c: new file from Emacs' sysdep.c.
4986 maybe configure should also check for sys_errlist.
4988 * configure.in (AC_REPLACE_FUNCS): add strerror.
4990 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4992 * debug.c (scm_init_debug): Added initialization for
4993 scm_evaluator_traps.
4995 * debug.h, debug.c: Various name changes.
4996 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
4997 "debug-options-interface". See commentary in options.c.
4999 * options.h, options.c: Options now have documentation strings.
5000 Also added a long explanatory commentary.
5002 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5005 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5006 last_debug_info_frame is now updated in all cases.
5008 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5011 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5013 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5014 Added option STACK_CHECKING.
5016 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5018 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5020 * __scm.h: Removed symbols for debugging support.
5022 * acconfig.h: Added symbols for debugging support.
5024 * configure.in: Added user option for debugging support.
5025 --enable-debug will include the debugging code into libguile.a.
5027 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5028 scm_relocate_chunk_to_heap.
5030 * debug.c: New file: low-level debugging support. It also
5031 includes support for debugging with gdb. (The extensions to gdb
5032 are written by Per Bothner at Cygnus.)
5034 * debug.h: New file: low-level debugging support.
5036 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5037 argument pairs. Extensive modifications to the debugging
5038 evaluator. Added "SECTION:" commentaries to clarify what happens
5039 when, during double compilation. Renamed EVALIMP --> EVALIM.
5040 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5041 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5042 the beginning of the file. New procedure: scm_unmemocopy.
5043 Added some global state variables needed by the debugging
5044 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5045 check_entry, check_apply, check_exit, debug_options and
5046 evaluator_traps. New acro: undefine.
5048 * eval.h: Renamed EVAL --> XEVAL.
5050 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5051 --> scm_make_weak_key_hash_table.
5053 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5054 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5056 * libguile.h: Conditionally include debug.h
5058 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5059 scm_object_properties shouldn't return handle. `handle' now gets
5060 initialized in scm_set_object_properties_x. scm_object_properties
5061 doesn't any longer create an entry in scm_object_whash.
5063 * options.c: New file: handling of run time options.
5065 * options.h: New file: handling of run time options.
5067 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5069 * print.c: New procedure: scm_print_options
5071 * print.h: Defines for print options.
5073 * read.c: New procedure: scm_read_options
5075 * read.h: Defines for reader options.
5077 * root.h: Added scm_source_whash among scm_sys_protects.
5079 * srcprop.c: New file: source properties.
5081 * srcprop.h: New file: source properties.
5083 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5084 (Bug found by A. Green.)
5086 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5088 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5090 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5092 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5094 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5095 and should be called by the final client.
5097 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5099 * gc.h: Use the PROTO macro when declaring functions.
5100 * gc.c: Use the PROTO macro when declaring static functions.
5101 Remove the CPP hair around function definitions.
5103 * gc.c (scm_init_storage): Initialize scm_asyncs.
5105 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5106 preprocessor symbol; "__scm.h" is where it might get #defined.
5107 * __scm.h: Similar: #include <scmconfig.h> before testing
5110 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5112 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5114 * init.c (scm_boot_guile): Add init_func argument; call
5115 (*init_func) instead of calling scm_appinit; it's ucky to
5116 hard-code names for the user's procedures.
5117 * init.h (scm_boot_guile): Adjust declaration.
5119 * __scm.h (PROTO): New macro, for declaring functions with
5122 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5123 eliminate all the __STDC__ conditionals.
5124 (scm_boot_guile): Add declaration.
5125 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5126 Remove __STDC__ conditionals around function definitions; the
5127 declarations in init.h will provide the same information, more
5130 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5131 complain about it in the error message; the error message is
5132 adequate without that note, and there's nothing the user can do
5135 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5137 * Makefile.in (ancillary): Drop def.sed.
5139 * posix.c (scm_init_posix): Use numeric values, rather than
5140 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5141 F_OK. The symbols aren't available on some systems, and I'm
5142 pretty sure their values are fixed by common widespread practice.
5143 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5145 More functions unavailable on some systems.
5146 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5147 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5149 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5150 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5151 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5152 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5153 stub that signals an error as the #else.
5155 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
5157 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
5159 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
5161 * unif.c: include ramap.h.
5163 * read.c (endif): case_insensative_p renamed case_insensitive_p.
5165 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
5167 * ports.c: include sys/ioctl.h.
5169 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
5171 * configure.in: check for sys/ioctl.h.
5173 * ports.c: include <malloc.h> not "malloc.h".
5175 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5177 * fports.c: remove ttyname and tmpnam declarations.
5179 * posix.c: fewer ttyname declarations.
5181 * fports.c: include <string.h> not "string.h".
5183 * init.c, ioext.c: include string.h and unistd.h.
5185 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5187 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
5188 genio.c, simpos.c, vports.c: include string.h.
5190 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
5192 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
5194 (scm_addr_buffer_size): change type from scm_sizet to int.
5195 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
5196 from scm_sizet to int.
5198 * error.c: include unistd.h.
5200 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
5203 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
5205 * __scm.hd, def.sed: deleted.
5207 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
5209 Changes for NeXT, suggested by Robert Brown.
5210 * configure.in: Call AC_TYPE_MODE_T.
5211 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
5212 NeXT. Put header file list in alphabetical order.
5213 * configure, scmconfig.h.in: Regenerated.
5214 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
5216 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
5219 * acconfig.h: New file, providing documentation for the CPP
5220 symbols defined in configure.in
5221 * acconfig-1.5.h: Removed; superceded by the above.
5223 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
5225 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
5227 * fports.c (scm_open_file): don't return #f, throw error.
5229 * ioext.c (fileno): renamed from %fileno.
5230 (soft-fileno): deleted.
5232 * ports.c (scm_port_revealed): don't need to check for -1 from
5234 (scm_set_port_revealed_x): return unspecified, not #f.
5236 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
5238 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
5240 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
5242 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
5244 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5246 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5247 This is necessary on Ultrix, and doesn't hurt portability.
5249 * Makefile.in (dist-dir): New target, implementing a new dist system.
5250 (installed_h_files): Put in alphabetical order.
5251 Remove duplicate entries for markers.h and unif.h.
5252 (c_files): Remove duplicate entries for markers.c.
5253 (ancillary): Renamed from anillery; all uses changed. Remove
5254 PLUGIN; it's a directory, and needs special treatment in dist-dir.
5255 Remove all the ../doc/* files; doc/Makefile.in handles that.
5257 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5259 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5260 every if must have an else, or else the whole command has a
5261 non-zero exit code whenever the if's condition is false.
5263 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
5265 * posix.c: include string.h.
5267 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
5269 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
5272 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
5273 Remove leading % from scheme names.
5274 Do not return error values, call SCM_SYSERROR or similar.
5276 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
5278 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
5280 * struct.c (scm_init_struct): new file.
5282 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
5284 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.

5520 initialization to fix a race condition.
5522 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

5549 The weird symbol syntax is also a bit bogus (emacs doesn't quite
