1 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3 * stime.c: Removed declaration of strptime. (It should be
4 declared by the system headers. If it turns out that some systems
5 don't, we'll handle that then.) (Thanks to Greg Troxel.)
7 * stime.h: Renamed TIMEH --> STIMEH
9 * backtrace.c (scm_display_error, scm_display_backtrace): In order
10 to increase portability, don't use structure assignment.
11 (Thanks to Nicolas Neuss.)
13 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
15 (finalize_fd_sets): Added empty statement after last case label.
16 (Thanks to Nicolas Neuss.)
18 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
21 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
23 * init.c, readline.c: OK, I won't have these readline.x bug
24 reports anymore. We've had them since April. The current reason
25 is a completely unintelligible failure of totoro.red-bean.com to
26 do the test for rl_getc_function in libreadline correctly. This
27 kludge overrides the test if we're on totoro so that the snapshot
28 generation process can work.
30 * readline.c: Define a strdup replacement if not existent on system.
32 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
34 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
35 This change makes scm_make_vector R5RS compatible. We cannot keep
36 the third argument since people want to be able to deduce the form
37 of the C function call only by looking at R5RS. (At the same time
38 we have removed some unnecessary complexity!)
40 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
41 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
42 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
43 argument in call to scm_make_vector.
45 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
47 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
48 This macro is useful in applications.
50 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
52 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
53 (scm_parse_path, scm_search_path): New Scheme level procedures.
55 * load.h (scm_internal_parse_path, scm_parse_path,
56 scm_search_path): Declared.
58 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
60 * filesys.c (dirname, basename): New procedures.
62 * init.c (scm_boot_guile_1): Removed condition around
65 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
66 new data type (guards) for representation of C level guards and
67 data on the wind chain.
68 (scm_internal_dynamic_wind): New function.
70 * dynwind.h: Declare scm_internal_dynamic_wind.
72 * root.h (scm_root_state): Added scm_cur_loadp.
74 * root.c (mark_root): Added comment about cur_loadp.
76 * load.c: #include "dynwind.h";
77 (scm_primitive_load): Use scm_inner_dynamic_wind to update
80 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
82 * ports.c (current-load-port): New procedure.
84 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
86 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
89 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
90 to Julian Satchell and Roland Kaufmann.)
92 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
93 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
95 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
97 * debug.h, debug.c (scm_start_stack): New function. Implements
98 the guts of old scm_m_start_stack.
100 * debug.c (scm_m_start_stack): Use scm_start_stack.
102 * init.c (scm_start_stack, scm_restart_stack): Renamed to
103 start_stack and restart_stack. (These have static scope.)
105 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
107 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
108 readline functions to come in release 2.3. (Thanks to Chet
110 (handle_errors): Use the above functions.
112 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
114 * readline.c: Improvements for readline support: Handle errors
115 better; Implement before-read-hook.
117 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
119 * init.c (scm_boot_guile_1), readline.c: Test for
120 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
121 assure that we have version >= 2.1.)
123 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
125 * readline.c (scm_add_history): Bugfix: Do strdup before giving
126 away the string to add_history.
127 (completion_function): Do completion for readline. (Thanks to
129 (scm_filename_completion_function): New procedure: Filename
131 (current_input_getc): New function. Use this one instead of
132 standard getc from readline.
134 * throw.c, throw.h (scm_handle_by_throw): New function: This
135 handler throws errors to next handler on the dynwind chain.
137 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
139 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
142 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
144 * procprop.c (scm_i_procedure_arity): New function. Returns arity
146 (scm_procedure_properties): Modified to return arity together with
148 (scm_procedure_property): Added the read-only property `arity'.
149 (scm_set_procedure_property_x): It is an error to set the `arity'
152 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
153 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
155 * procprop.h (scm_sym_arity): New symbol.
157 * objects.c (scm_set_object_procedure_x): New procedure: Use this
158 to set the dispatch procedure of an operator or entity object.
160 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
161 Made procedure slots read-only.
163 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
164 scm_tcs_cons_gloc case in zero args switch; Fixed args
165 construction for operators in scm_tcs_cons_gloc case in two args
168 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
170 * fluids.c: Removed use of assert.h (in order to avoid
173 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
175 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
177 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
178 change makes the evaluator safer at the cost of evaluation speed.
179 It handles the case when the user has added a non-immediate
180 improper end of the application form, e.g., `(+ 0 . x)'.
181 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
182 minimize the extra cost as much as possible. The new code is
183 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
184 problem with structs planted directly in the code (e.g. by a
185 macro). This no longer causes segmentation fault. (Thanks to
188 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
189 arg `proc' in order to be able to throw errors; New argument
192 * Removed extra #include "debug.h"
194 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
196 * scmsigs.c: Declare usleep as returning void on some systems.
197 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
200 * coop.c (usleep): Return void on some systems.
202 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
204 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
206 * coop.c: Changed return type of usleep to int.
208 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
209 isn't found in the OS.
211 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
212 isn't enabled. (Thought that I had made this change ages ago...)
214 * iselect.c: Declare bzero if not defined by OS.
216 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
218 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
219 condition. (Thanks to John Tobey.)
221 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
222 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
225 * __scm.h: Start the long-term project of moving to POSIX threads.
226 Phase 1: Classification of all critical sections.
227 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
228 for A sections. (See comments in __scm.h for details.)
230 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
231 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
233 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
235 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
236 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
237 (libpath.h, versiondat.h): Replaced dependency on Makefile with
238 dependencies on $(srcdir)/Makefile.in
239 $(top_builddir)/config.status in order to avoid circularity.
241 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
242 from argc if argc was 0 initially.
244 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
245 in generation of libpath.h.
247 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
249 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
250 libguile from 2 to 3.
252 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
254 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
256 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
258 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
259 scm_set_port_column_x, scm_port_filename,
260 scm_set_port_filename_x): Removed optional arguments. Added
261 proper argument checking.
263 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
264 stack size in machine words.
266 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
267 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
268 to Ole Myren Röhne.)
270 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
272 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
273 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
275 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
278 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
279 procedure apply: Copy argument lists before pushing them unto the
280 environment so that the environment won't get mutated due to
281 manipulation of procedure arguments. This should perhaps be
282 regarded as a temporary solution until someone finds a more
283 efficient one. (Thanks to Maciej Stachowiak.)
285 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
287 * script.c (scm_compile_shell_switches): Use "guile" as default
288 zero arg if argc is NULL.
290 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
292 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
293 is zero. (Thanks to Dirk Herrmann.)
295 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
297 * ports.c (scm_add_to_port_table): First line is now line 0
298 (was 1). (Interface changed according to suggestion by Per
301 * backtrace.c (display_header): Add 1 to line and column numbers
302 when presenting them to the user.
304 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
305 from debug.c --> eval.c
307 * eval.h, eval.c (scm_eval_options_interface): New options
309 (SCM_EVAL_STACK): New option: Size of newly created stacks,
310 i.e. stacks for new threads.
312 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
314 * eval.c (unsafe_setjmp): Removed with #if 0.
316 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
319 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
320 to avoid compiler warnings.
322 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
324 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
326 * throw.c (handler_message): Print message on current error port
327 instead of default error port. (Thanks to Maciej Stachowiak.)
329 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
331 * ports.c (scm_add_to_port_table): allocate in units of
332 struct scm_port_table *, not struct scm_port_table.
333 * posix.c (scm_close_pipe): remove the port from the port table
335 Thanks to Rob Engle for both fixes.
337 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
339 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
340 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
342 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
344 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
346 * backtrace.c (display_error_body, display_backtrace_body),
347 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
348 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
349 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
350 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
353 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
354 don't receive the jmpbuf arg anylonger.
355 (scm_catch): Don't accept a #f tag.
356 (scm_throw): Check that key is a symbol.
357 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
359 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
361 * async.c (async_pending): Removed declaration.
363 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
365 * dynwind.c (scm_wind_chain): New debug function.
367 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
368 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
369 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
370 extra layer of functions around the body and handler of a thread.
371 This extra layer makes sure that the handler is called in the
372 dynamic context of the surround (= empty dynwind list), but under
373 the *dynamic root* of the body. We can not use the dynamic root
374 of the surround since that root belongs to another thread => stack
375 is not handled correctly. It may seem ugly to use this extra
376 layer, but the extra cost in terms of execution time is really
377 negligible compared to the total amount of time required to create
378 a thread, and it would reduce maintainability to duplicate the
379 crucial and complicated steps performed by cwdr.
381 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
382 (SCM_ALLOW_INTS): Added thread switching code before interrupts
383 get re-enabled. The important effect of this is that interrupts
384 are blocked during thread switching so that thread data structures
385 don't risk getting messed up by an unfortunate signal.
386 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
387 seems to do more aggressive optimization which actually move
388 instructions around in these macros in a fatal way. Therefore:
389 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
390 just superstitious...)
391 (SCM_TICK): Maybe do a context switch and take care of asyncs.
392 This macro should be used instead of SCM_ASYNC_TICK since the
393 latter doesn't do context switches any more.
395 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
396 instead of SCM_ASYNC_TICK.
398 * coop.c, iselect.c: Since thread switches are now performed with
399 interrupts masked, we can't use the old mechanism of delivering
400 signals immediately when they arrive. Signals must instead be
401 delivered when the asyncs run *after* the end of the critical
402 section in scm_internal_select. But this also means after context
403 switch so that the signal will be delivered to a different thread.
404 To avoid this, I have changed the protocol of
405 coop_wait_for_runnable_thread and friends so that they are allowed
406 to return the original thread. So, if a signal arrives during
407 scm_internal_select, we won't any longer be forced do a context
408 switch, but can remain in the same thread and deliver the signal
411 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
412 scm_asyncs_pending and made it global.
414 * iselect.c: Small fixes.
416 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
417 coop_condition_variable_init, coop_condition_variable_wait,
418 coop_condition_variable_signal): Changed return type from `void'
419 to `int'. This is to adhere closer to the pthreads interface.
420 This, in turn, is part of an attempt to provide C versions of the
421 mutex and condition variable primitives which can be part of a
422 frontend to COOP or pthreads.
424 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
425 coop_condition_variable_destroy): New functions.
427 * coop-threads.c (scm_wait_condition_variable): Use
428 coop_condition_variable_wait_mutex.
430 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
431 Definitions moved to coop-defs.h.
433 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
434 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
435 scm_cond_destroy): New C interface to mutecis and cond vars.
437 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
439 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
441 * iselect.c: Now several threads can wait on the same file
442 descriptor. The behaviour is compatible with OS select: All
443 threads waiting for the fd return with the same status.
445 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
447 * coop-threads.c, threads.h (scm_spawn_thread): New function.
448 Can spawn a thread from application C code.
450 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
452 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
453 gh_doubles2scm): New functions.
455 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
457 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
458 commented-out version of gh_eval_str()
460 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
462 * socket.c (scm_bind): free soka after use.
464 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
466 * stime.c (tzvar): new variable.
467 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
468 avoid memory leaks when allocating.
470 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
472 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
475 * gc.c, tags.h: Doc fixes.
477 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
479 * eval.c (macro-eval!): Removed. This function was a design bug.
480 It allowed memoized code to leak out to the scheme level. Most
481 things that you could do with `macro-eval!' can be done with
484 1997-12-20 Tim Pierce <twp@skepsis.com>
486 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
487 scm_fgets now depends on ftell(3) to know how many bytes were
490 1997-12-15 Tim Pierce <twp@skepsis.com>
492 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
493 dealing with strings.
495 1997-12-13 Tim Pierce <twp@skepsis.com>
497 Make %read-line more suitable for implementing read-line efficiently.
498 * ioext.c (scm_read_line): Strip the terminating newline from a
499 string, and return a cons of the string and its terminator.
501 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
502 of the string that is read is stored in this memory location.
503 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
504 * genio.c, genio.h (scm_do_read_line): Update caller.
505 * ports.h (scm_ptobfuns): Update typedef.
506 * fports.c (scm_fptob, scm_pipob): Update struct.
508 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
510 * filesys.c (set_element): Return file descriptor.
511 (fill_select_type): Return the highest file descriptor.
512 (scm_select): Tell select about the highest file descriptor. On
513 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
514 Therefore the extra overhead for calculating the maximum fd seems
515 to be more than compensated. Is this correct? In any case,
516 scm_internal_select will be much faster with this info.
517 (scm_select, fill_select_type, set_element): Don't accept any kind
518 of object in the file descriptor list or vector.
520 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
522 * iselect.c (finalize_fd_sets): Bugfix.
524 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
526 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
527 when using scm_internal_select (since we might switch to another
530 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
532 * simpos.c (scm_system): always define: use sysmissing if not
533 available. Check for HAVE_SYSTEM instead of _Windows (does
534 Windows lack system or does it have an unusable one?).
535 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
536 Let the argument be optional: if not supplied, call system(NULL).
538 * ports.c (scm_close_port): relax the type check from OPPORTP to
539 PORTP; closing a closed port is allowed.
541 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
543 * fports.c (scm_fgets): Return if the last char in a chunk is
544 newline. When fgets returns a string whose length is `size-1', it
545 is ambiguous whether a whole line was retrieved, so we must check
546 explicitly whether a line terminator is present.
548 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
550 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair

572 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
574 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
575 errno macro expansion of this field name. (errno is a C

605 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
606 after scm_init_fluids.
608 1997-11-28 Tim Pierce <twp@skepsis.com>
610 * iselect.c: #ifdef USE_THREADS around thread-related includes.
612 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
613 DLSYM_ADDS_USCORE to decide whether to add an underscore.

617 * iselect.c (coop_next_runnable_thread,
618 coop_wait_for_runnable_thread): Disable interrupts so that no
619 async is executed before a potential error_revive.

631 replacement in iselect.c.
632 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
633 coop_join): If GUILE_ISELECT enabled, use
634 coop_wait_for_runnable_thread instead of
635 coop_next_runnable_thread.
636 (usleep, sleep): New replacements for system functions if
637 GUILE_ISELECT is enabled.
639 * coop-threads.h: Declare coop_wait_for_runnable_thread.
641 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
643 * filesys.c: Added #include "iselect.h". Moved FD-macros to
644 iselect.h. Implement Scheme level `select' using
645 scm_internal_select. (See NEWS.)
647 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
649 * init.c: Call scm_init_iselect.

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

674 gh_repl (argc, argv).
676 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
678 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
679 and to invoke scm_shell().
680 (gh_launch_pad): took out the loading of boot-9.scm from here,
681 since it is probably best to let the user control that. In fact,
682 gh_repl() now invokes scm_shell() which does that.
684 1997-11-23 Mark Galassi <rosalia@cygnus.com>
686 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()

711 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
713 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
714 configure.in was changed).

733 scm_close_all_ports_except, scm_set_current_output_port,
734 scm_set_current_error_port): Likewise
735 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
736 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):

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

755 * strings.c: Formatting tweaks.
757 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
758 variable first; then SCHEME_LOAD_PATH, with a warning message.
759 (scm_parse_path): New function.
760 * script.c: Doc fixes.

791 (gh_assoc): added these gh_ functions implemented as macros.
793 * gh_predicates.c (gh_null_p):

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

873 * gh_test_c.c (c_vector_test): some improvements on the vector
876 * gh.h (gh_vector): this used to exist but do the wrong thing.
877 Now it (almost) does the right thing, though it takes a list
878 instead of the individual arguments. I need to see how it could
880 (gh_list_to_vector): added this function as a macro. Corresponds
881 to Scheme's (list->vector ...).
882 (gh_vector_to_list): added this function as a macro. Corresponds
883 to Scheme's (vector->list ...).
885 * gh_data.c (gh_vector_ref): renamed from gh_vref to

937 the type represented by this vtable.
939 * print.c (scm_iprin1): Don't print arguments of macro
940 transformers. (They are always: exp env.); Bugfix: Unmemoize
941 transformer source with correct environment.
943 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
945 Streamlining of call-with-dynamic-root:

952 but take args that are more useful to C code. Also, the handler
953 is now invoked *outside* of the new dynamic root, like the docs

955 is responsible for using a handler that does not throw, if he
957 (cwdr): Reimplemented in terms of scm_internal_cwdr.
958 * root.h (scm_internal_cwdr): New prototype.
960 Even more but risky streamlining:
962 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
963 allocation of the jumpbuf of a root continuation. The changes
964 below are controlled by it. They are now deactivated.
965 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
966 the JMPBUF of the scm_rootcont to NULL before returning.
968 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
969 when they are non-NULL.

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

1006 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1008 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1009 was looping endlessly.
1011 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1013 * strports.c (scm_eval_string): Don't close the port.
1015 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1016 former returns a nice normal integer. (Thanks to Daniel

1021 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1022 makefile variable as a build parameter called LIBS. The
1023 build-guile program will use this, for the time being.
1024 * Makefile.in: Regenerated.
1026 Thanks to Shiro Kawai:
1027 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1028 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1031 * Makefile.in: Regenerated with automake 1.2a.
1033 * script.c (scm_compile_shell_switches): If we hit the -c or --
1034 arguments, don't set the car of (command-line) to scm_usage_name,
1035 the prettified name of the guile executable; give it the full
1036 path, the way shells usually handle $0.
1038 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1040 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1041 Scheme-level name `array-map' and renamed `serial-array-map' to
1042 `serial-array-map!'.
1044 * backtrace.c: Introduced exception handlers which now enclose
1045 `display-error' and `display-backtrace' so that error reporting
1046 won't get into infinite loops if an error occurs during displaying
1047 of the error. This can very easily happen with user supplied
1048 print call-back routines.
1050 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1052 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1053 the names `serial-array-map' and `array-map' should be removed.)
1055 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1057 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1058 Added #include "objects.h"
1060 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1061 Add #include "feature.h".
1063 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1064 (modinclude_HEADERS): Added objects.h.
1066 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1067 This test is needed at many places in the code and should be
1068 abstracted. (Motivated by the need of this test in libguiletk.)
1070 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1071 (scm_eval_string), load.c (scm_primitive_load,
1072 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1073 Use SCM_EOF_OBJECT_P.
1075 * eval.c (scm_init_eval): Add feature `delay'.
1077 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1079 * scmhob.h: Removed.
1081 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1083 * list.h (SCM_LISTn): New macros. Make list creation in C code
1084 prettier. The idea comes from STk.
1086 * sequences.h, sequences.c, append.h, append.c: Removed. These
1087 files implemented non-R4RS operations which would encourage
1088 non-portable programming style and less easy-to-read code.
1090 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1093 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1094 sequences.h, #include append.h.
1096 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1099 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1101 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1103 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1105 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1107 * eval.c: Added #include "objects.h"
1109 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1112 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1113 adjacent smob numbers.
1115 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1117 * procprop.h: Added declaration of scm_i_inner_name.
1119 * gsubr.c: New global symbol scm_i_inner_name.
1121 * debug.c (scm_procedure_name): Try procedure property
1122 `inner-name' if `name' fails.
1124 * print.c (scm_iprin1): Use scm_macro_name.
1126 * eval.c (scm_m_define): Give names to macros as well; Only the
1127 first top-level definition gives a procedure/macro a name.
1128 Otherwise confusing names can turn up in backtraces.
1129 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1130 `name'; Give names to macros as well.
1132 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1133 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1136 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1138 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
1140 (prinmacro): Removed. The code has been moved/merged into print.c
1141 in order to decrease code redundancy. We want macros to print in
1142 a way equivalent to procedures, and it would be silly to duplicate
1143 the required code. (We don't want to maintain two places.)
1144 (macrosmob): Print field is now a NULL pointer.
1146 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1147 scm_macro_transformer): New prototypes.
1148 (scm_tc16_macro): Declared.
1150 * * print.c (scm_iprin1): Added code for printing of macros. Macros
1151 are now printed in a way equivalent to procedures.
1153 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1155 * procs.h (scm_closure_p): Added declaration.
1157 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1159 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
1160 Shouldn't pass "heap" as the subr name.
1162 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1164 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
1165 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
1166 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1167 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1168 SCM_BOOL_T. Any non-false value is true.
1170 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1172 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1173 scm_gensym): Added prototypes.
1175 * symbols.c (scm_gensym): New function. This will speed up
1176 certain types of applications (such as macro systems) which
1177 generate lots of symbols.
1179 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1181 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
1183 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
1185 * unif.c (scm_shap2ra): tighten the checking of the array dimension
1186 specifier, since (2) or (2 . 3) would cause SEGV.
1187 (scm_transpose_array): more argument checking fixes.
1189 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1191 * Makefile.in: Regenerated.
1193 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1195 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
1197 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1199 * error.c, error.h (scm_error_callback): Removed (see NEWS).
1201 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
1203 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
1204 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
1207 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
1208 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1209 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
1210 scm_array_p, scm_array_rank, scm_array_dimensions,
1211 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
1212 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
1213 scm_array_prototype): Added case scm_tc7_wvect.
1215 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
1217 * errno.h: prototype for scm_strerror.
1218 * error.c (scm_strerror): new procedure.
1220 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1222 * list.c (scm_list_append_x): Allow non-pair as last argument.
1223 This is consistent with the R4RS append and is probably the
1224 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1226 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1228 * stime.h: prototype for scm_times.
1229 * stime.c (scm_times): new procedure.
1230 * ioext.c (scm_fseek): if the first argument is a file descriptor
1232 (scm_ftell): if the first argument is a file descriptor call lseek
1234 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
1235 * filesys.c (scm_chmod): if the first argument is a file descriptor,
1237 (scm_chown): if the first argument is a port or file descriptor,
1239 (scm_truncate_file): new procedure.
1240 Add DEFER/ALLOW INTS to a few other procedures.
1241 (scm_fsync): new procedure.
1242 (scm_open_fdes): new procedure.
1243 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
1245 (scm_fcntl): the first argument can now be a file descriptor. The
1246 third argument is now optional.
1248 * posix.c (scm_execl, scm_execlp): make the filename argument
1249 compulsory, since omitting it causes SEGV.
1250 (scm_sync): return unspecified instead of #f.
1251 (scm_execle): new procedure.
1252 (environ_list_to_c): new procedure.
1253 (scm_environ): use environ_list_to_c. disable interrupts.
1254 (scm_convert_exec_args): take pos and subr arguments and
1255 improve error checking.
1257 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1259 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1260 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1261 argument to SCM_ASSERT. Furthermore, the name of the function
1262 should be passed as first argument when signalling
1263 SCM_WNA. (Thanks to Thomas Morgan)
1265 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1266 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1267 dispatches on the number of actual args has a default case
1268 reporting an internal error. This is a vestige from a version
1269 that mallocated a SCM vector to hold the arguments. In the
1270 current version this check is too late: if it ever happens we will
1271 have already overstepped the bounds of the array.
1273 Also, the patch [...] adds a check for too many actual arguments."
1275 mdj: Removed check for "internal programming error".
1277 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1279 * gh_io.c (gh_write): New function.
1281 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
1282 throw.c (scm_internal_stack_catch): New sibling to the other catch
1283 functions. Code moved from gh_eval.c.
1284 throw.h: Added header.
1285 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
1286 scm_internal_stack_catch.
1288 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1290 * ioext.h: fix up prototypes.
1291 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
1292 Scheme name is now dup->fdes.
1293 (scm_dup_to_fdes): make the second argument optional and
1294 fold in the functionality of scm_primitive_dup.
1295 (scm_primitive_dup): deleted.
1297 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1299 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
1300 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
1301 ultrix are defined. Use setvbuf instead of setbuf.
1302 (scm_setvbuf): new procedure.
1303 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
1304 (scm_setfileno): moved from ioext.c.
1305 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
1306 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
1308 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1310 * fluids.c (scm_fluid_p): New function.
1311 * fluids.h (scm_fluid_p): New prototype.

1315 * print.c (scm_iprin1): Enter printed structures into the print
1316 state as nested data while they are printed.
1317 (print_state_fluid, print_state_fluid_num): New variables.
1318 (scm_init_print): Initialize them.
1319 (scm_iprin): If print_state_fluid carries a print_state, use that
1320 instead of creating a new one.
1321 (scm_printer_apply, apply_stub, struct apply_data): New
1322 definitions to help with calling printer functions written in
1324 * print.h (scm_printer_apply): New prototype.
1326 * struct.c (scm_print_struct): Use scm_printer_apply to call the
1327 user defined struct printer.
1329 * dynwind.c (scm_dowinds): Handle fluids on the wind list.
1330 * fluids.h (scm_internal_with_fluids, scm_with_fluids,

1335 Fri Jul 25 12:05:46 1997 Marius Vollmer <mvo@zagadka.ping.de>
1337 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
1338 SCM_ASSERT: arg comes before pos.
1340 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1342 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
1343 to a list of length zero correctly.
1345 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1347 Supply an `fgets' method for port objects to do fast line i/o.
1348 * ioext.c (scm_read_line): New function.
1349 * genio.c (scm_gen_read_line): New function.
1350 * fports.c (scm_fgets): New function.
1351 (scm_fptob, scm_pipob): Add scm_fgets method.

1361 * ioext.h: removed scm_duplicate_port prototype.
1363 * ioext.c (scm_primitive_dup2): return the new file descriptor
1364 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
1366 (scm_fdopen): bug fix: don't try to make port unbuffered until its
1367 stream has been set.
1368 (scm_duplicate_port): deleted, there's now an implementation in
1370 (scm_primitive_dup2): do nothing if newfd == oldfd.
1372 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
1374 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
1377 * ioext.h: new prototypes.
1378 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
1380 * fluids.c (next_fluid_num): don't do
1381 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
1383 * ports.h: prototypes too.
1384 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
1386 * fports.h: prototype too.
1387 * fports.c (scm_evict_ports): moved from ioext.c.
1389 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
1391 * ports.c (scm_close_port): return a boolean instead of unspecified.
1392 throw an error if an error other than EBADF occurs.
1394 * filesys.h: scm_close prototype.

1396 and ports (scsh compatible).
1398 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
1401 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
1403 * fluids.c, fluid.h: New files.
1404 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
1405 (modinclude_HEADERS): Added "fluids.h"

1414 (scm_make_root): Call scm_copy_fluids to make fluid bindings
1415 unique for the new root when it has a parent.
1417 * smob.h: Include "libguile/print.h" to make scm_print_state
1420 * dynl.c (free_dynl_obj): New function to free the dynamic object
1421 data. (dynl_smob): Use it.
1422 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
1423 the dynamic object data below the linking of the object to avoid
1424 memory leak when the linking code throws an error. Now the code
1425 leaks a whole dynamically linked library when must_malloc throws,
1426 but that should be much less likely.
1428 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
1430 Changes to compile under gnu-win32, from Marcus Daniels:
1431 * stime.c (tzset): If tzset isn't provided, make it a NOP.
1432 (scm_localtime): Change SCM_EOF to SCM_EOL.
1433 (scm_mktime): Likewise.
1434 * socket.c: Don't include sys/un.h unless autoconf tells
1435 us Unix domain sockets are available.
1436 (scm_fill_sockaddr): Ignore Unix domain code.
1437 (scm_addr_vector): Likewise.
1438 (scm_init_addr_buffer): Likewise.
1439 (scm_socketpair): Don't include unless socketpair was

1442 * scmsigs.c (scm_pause): Don't include unless pause was found
1444 * posix.c (scm_getgroups): Don't include unless support function
1445 was found during autoconf (in this case, getgroups).
1446 (scm_setpwent): For setpwent.
1447 (scm_setegid): For setegid.
1448 * net_db.c (scm_inet_netof): Don't include unless support
1449 function was found during autoconf (in this case, inet_netof).
1450 (scm_lnaof): For inet_lnaof.
1451 (scm_inet_makeaddr): For inet_makeaddr.

1463 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
1464 scm_misc_error, not SCM_EOF.
1466 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
1467 arguments for formatting the error message, not SCM_BOOL_F. I
1468 think this is left over from the (eq? '() #f) days.
1470 * read.c (recsexpr): Give this a dummy definition if
1471 DEBUG_EXTENSIONS isn't #defined.
1473 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
1475 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
1478 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>

1485 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
1486 alloca.lo will be included in @LIBLOBJS@. Something better than
1487 this should be possible.
1488 * Makefile.in: Regenerated.
1490 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1492 * simpos.h: prototype for scm_primitive_exit.
1493 * simpos.c (scm_primitive_exit): new procedure, terminates the
1494 process without unwinding the stack.
1496 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
1498 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
1499 argument and logior its components together, so the user doesn't
1500 have to do this explicitly. Also, if regexp/basic is supplied, then
1501 turn off REG_EXTENDED.
1502 (scm_init_regex_posix): New regexp/basic symbol.
1503 (REG_BASIC): #define this if it is not already present.
1505 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1507 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
1508 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
1509 (CLEANFILES): New target, clean versiondat.h, libpath.h.
1510 (DISTCLEANFILES): New target, clean *.x.
1511 * Makefile.in: Regenerated.

1515 * script.c (scm_compile_shell_switches): Add 1997 to copyright
1516 years in usage message.
1518 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
1519 * Makefile.in: Regenerated.
1521 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
1522 flag; I don't think we support it.
1523 (scm_make_regexp): Make sure the user doesn't pass the
1526 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
1528 (scm_init_regex_posix): Define constants for the REG_mumble flags;
1529 name them according to the SCSH convention: regexp/mumble.
1531 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
1533 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
1535 * Makefile.am (libpath.h): Include the values of all the standard
1536 Makefile directory variables. Print a message, but don't print
1538 (versiondat.h): Print a message, but don't print all the commands.
1539 * load.c: #include "alist.h".
1540 (init_build_info): New function.
1541 (scm_init_load): Call it.
1542 * Makefile.in: Regenerated.
1544 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
1546 * root.c: Establish a reliable catch-all handler for the new root.
1547 After all the Scheme handler function might signal an error too,
1548 and we don't want to lose that.
1549 (cwdr_inner_body): Renamed from cwdr_body.
1550 (cwdr_outer_body): New function, to establish the user's handler,
1551 and pass control to cwdr_inner_body.
1552 (cwdr): Establish the reliable catch-all handler here, and pass
1553 control to cwdr_outer_body.
1554 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
1555 the user's handler through to cwdr_outer_body.
1556 * throw.c (scm_handle_by_message): Move guts into....
1557 (handler_message): New static function.
1558 (scm_handle_by_message_noexit): New function.
1559 * throw.h (scm_handle_by_message_noexit): New prototype.
1561 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
1562 across this. Only works on GCC. Otherwise, we hope for the best.
1563 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
1564 the feeling that real thread systems will not need this...
1566 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
1568 Try to detect when people are using one version of libguile and a
1569 different version of ice-9. People have been skewing things and
1570 sending in bug reports.
1571 * Makefile.am (versiondat.h): New file to generate.
1572 * version.c: #include "versiondat.h", to get version info.
1573 (scm_libguile_config_stamp): New function.
1574 * script.c: #include "version.h".
1575 (scm_compile_switches): Call scm_version to get version number.
1576 * scmconfig.h.in, Makefile.in: Regenerated.
1577 * Makefile.in: Regenerated.
1579 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
1580 primitive definitions under their Scheme names.
1582 * Makefile.am (libguile_la_LDFLAGS): Update library version to
1583 1:2. Helps avoid confusion between installed and uninstalled libs.
1585 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
1588 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
1589 backslash from definition; this should be used like: GDB_INTERFACE;
1591 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1593 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
1594 new port unbuffered until its stream has been set.
1596 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
1598 * ports.h: new prototype.
1599 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
1601 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
1603 Make things compile neatly under Sun's C compiler.
1604 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
1605 * extchrs.c (xmbtowc): Make the second arg a normal char, not
1606 unsigned, because that's what the ANSI function takes.
1607 * extchrs.h (xmbtowc): Corresponding change to prototype.
1608 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
1610 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
1611 argument plain char *.
1612 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
1614 * tag.c (scm_tag): Remove unreachable statement.
1615 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
1616 top of the word, it should be unsigned.
1618 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
1619 is defined, to avoid warnings; it's only used in the
1620 conflict-checking code. Which might go away anyway.
1621 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
1622 conditionals; put the label definition in an #if too, to stifle
1625 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
1626 ChangeLog-threads in the distribution.
1627 * Makefile.in: Regenerated.
1629 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1631 * guile-snarf.in: Changed regexp to support CPPs that insert
1632 whitespace between lexical tokens (which munges the `%%%' snarf
1635 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1637 * load.c (scm_init_load_path): Append $(datadir)/guile to
1638 %load-path, so modules do not have to be installed in Guile's
1639 current version directory.
1641 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
1643 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
1644 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
1645 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
1646 call the sysdep functions with deferred ints.
1647 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
1648 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
1649 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
1652 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
1655 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
1657 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
1659 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
1661 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
1664 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
1666 * eval.c (scm_lookupcar1): New procedure to cope with a race
1667 condition during lookup (when using threads).
1668 (scm_lookupcar): Implement in terms of scm_lookupcar1.
1669 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
1672 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
1674 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
1675 supplied. (Change from Tim Pierce.)
1677 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
1679 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
1680 23:47:01 1997" changelog: Slots are now initialized with `#f' by
1681 default and not `()'. `#f' is the canonical non-value in Scheme,
1684 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1686 * struct.c (struct_printer): New variable that holds a handle on
1687 the Scheme variable *struct-printer*. This variable can be set by
1688 Scheme code to override the printing of structures.
1689 (scm_print_struct): If struct_printer is set, call it. If it is
1690 not set, or returns #f, print the structure in the old fashion.
1691 Include "eval.h" for scm_apply.
1693 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
1695 * struct.c (scm_struct_ref, scm_struct_set_x): Use
1696 scm_struct_i_n_words to get the number of fields, not
1697 -scm_struct_n_extra_words.
1699 On the route to fancier struct printing:
1700 * struct.c (scm_print_struct): New function to print a structure.
1701 Include "genio.h" to support it. This function doesn't do
1702 anything interesting right now, but I think it should be here
1704 * struct.h: Include "print.h" and add prototype for
1706 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
1707 print structures ourself.
1709 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
1711 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
1712 before applying the handler in case it doesn't return.
1714 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
1716 * scmsigs.h, async.h: updated.
1718 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
1721 * posix.c (scm_uname): interpret only negative values as an error.
1722 Solaris normally returns a positive value.
1724 * script.c (scm_compile_shell_switches): if we are not going into
1725 an interactive repl, set scm_mask_ints to zero so that asyncs can
1728 * simpos.c (scm_system): don't ignore/unignore signals around
1731 * posix.c (scm_open_pipe): don't ignore/unignore signals around
1734 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
1735 done in boot-9.scm instead.
1737 * scmsigs.c, async.c: Major rewriting of signal handling code.
1738 (scm_sigaction): new procedure.
1739 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
1741 (scm_raise): return unspecified, throw error on failure.
1743 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
1745 * regex-posix.c (scm_init_regex_posix): Register the "regex"
1746 feature, to help boot-9.scm decide whether to import the regex
1749 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
1751 * eval.c: Include scmconfig.h at the beginning of the file so that
1752 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
1755 * regex-posix.c: #include "_scm.h" before conditionally #including
1756 <regex.h>; the former defines HAVE_REGCOMP.
1758 * regex-posix.c: #include <regex.h> conditionally, so the file is
1759 CPP'able (for dependency scanning) even on systems that don't have
1762 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
1764 Add new R4RS-compliant syntax for keywords.
1765 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
1766 regardless of the setting of the `keywords' read option.
1767 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
1768 can be re-read no matter what the setting of the `keywords' read
1771 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
1773 Add support for POSIX regular expressions.
1775 * regex-posix.c, regex-posix.h: New files. (Some code
1776 is taken liberally from rx/rgx.c in the old Guile dist.)
1778 * init.c: Include regex-posix.h.
1779 (scm_boot_guile_1): Call scm_init_regex_posix.
1781 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
1782 Add regex-posix.[ch] sources.
1783 * Makefile.in: Regenerated.
1785 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
1786 to do this automatically? It didn't for me, bleh.)
1788 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
1790 * fports.c (print_pipe_port): New function.
1791 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
1792 latter doesn't even take the right arguments.
1794 * Makefile.am: Increment shared lib revision number. I think
1795 sometimes the uninstalled Guile finds the installed shared lib;
1796 Gord says doing this might help. As things turned out, I can't
1797 say whether it does.
1798 * Makefile.in: Regenerated.
1800 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
1801 passing it as the closure argument to scm_boot_guile. (Bill
1804 * ports.c (print_void_port, putc_void_port, puts_void_port,
1805 write_void_port, flush_void_port, getc_void_port, close_void_port,
1806 noop0): Use ANSI prototypes instead of K&R declarations, so the
1807 initialization of void_port_ptob gets aggressively type-checked.
1808 Fix arguments of print_void_port and write_void_port. (Bill

1842 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
1844 * script.c (scm_find_executable): Use prototype-style definition
1845 here; apparently it's not quite right to have const in a prototype
1846 and then use a K&R declaration. I wonder if stuff like this will
1847 go away if we compile with -Wrequire-prototypes, or whatever that
1848 is... (Bernard URBAN)
1850 * scmhob.h: New text from Bernard URBAN.
1852 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
1854 * script.c: Don't #define const on hpux. Configure takes care of
1855 this. (Thanks to Larry Schwimmer.)
1857 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
1858 decide whether to #include <unistd.h>, instead of listing a bunch
1859 of systems. Don't #include stdio twice. Removed dyked-out
1860 definition of scm_find_impl_file.
1862 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
1864 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
1865 library version info to 1:0.
1866 * Makefile.in: Regenerated.
1868 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

1872 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
1873 throw.c: Update copyright years; these files have been worked on
1874 significantly in 1997, but only had copyright years for 1996.
1875 Also, change name of copyright holder on some from Mikael
1876 Djurfeldt to Free Software Foundation; he has signed papers
1877 assigning the changes to the FSF.
1879 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
1880 reason not to give the user the option.
1882 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
1883 Return #f on end-of-file when scanning table (i.e. when called
1884 with no arguments). Try to catch errors, when we can.
1885 * posix.c (scm_getgrgid, scm_getpwuid): Same.
1887 * script.h (scm_shell_usage, scm_compile_shell_switches): New
1888 external declarations. These are useful.
1890 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
1892 * posix.c: don't include <sys/select.h> or define macros for
1893 select, since they were not used in this file.
1895 * filesys.c (scm_select): make the fifth parameter microseconds,
1896 not milliseconds. let the fourth parameter be either a real value
1897 or an integer or #f. The first, second and third arguments can
1898 now be vectors: the type of the corresponding return set will be
1900 (set_element, get_element): new static procedures.
1902 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
1904 * strports.c (scm_eval_string): New function.
1905 (scm_eval_0str): Trivially re-implemented in terms of
1907 * strports.h (scm_eval_string): New extern decl.
1909 * net_db.c (h_errno): Add extern decl for this.
1911 * fports.c (local_pclose): New function.
1912 (scm_pipob): Use it in the initializer here.
1915 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
1916 Use a meaningful error message when signalling an error. For
1917 this, scm_gethost must check h_errno rather than errno.
1919 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
1921 * Makefile.in: Regenerated, using automake-1.1p.
1923 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
1925 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
1926 not SCM_UNSPECIFIED.
1928 * script.c (scm_compile_shell_switches): don't append (quit) if
1930 (scm_shell): call scm_exit_status and exit on the result of the
1933 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
1935 Ensure that shared substrings are handled properly when passed to
1936 a system call or other foreign function. Many thanks to Tim
1938 * symbols.h (SCM_COERCE_SUBSTR): new macro.
1939 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
1940 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
1941 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

1968 (scm_compile_shell_switches): Use it.
1970 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1972 * filesys.c (scm_input_waiting_p): add missing third argument to
1975 * stime.c (scm_localtime): copy the result of localtime before
1976 calling gmtime in case they share a buffer.
1977 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
1980 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
1982 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
1984 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
1986 * Makefile.am (check-local): New target, which causes 'make check'
1987 to run gh_test_c and gh_test_repl, with some trivial input.
1988 * Makefile.in: Rgnrtd.
1990 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>

1995 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
1997 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
1998 sure how this was supposed to work.
1999 (scm_async_click): don't send SCM_TICK_SIGNAL.
2000 (scm_init_async): don't initialize %tick-thunk.
2002 * the following change doesn't affect the Scheme interface:
2003 gc-thunk is called at the end of garbage collection. however it's
2004 no longer implemented by pretending it's a signal.
2006 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2007 system async corresponding to scm_gc_thunk.
2008 * async.h: declare scm_gc_async.
2009 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2010 gc-thunk directly, instead of going through a signal handler.
2011 (scm_gc_async): new variable, points to the GC system-async.
2012 (scm_init_async): save the GC async as scm_gc_async instead
2013 of using system_signal_asyncs.

2016 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2018 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2019 Don't screw up if we're interrupted.
2020 * Makefile.in: Regeneradet.
2022 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2024 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2026 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2027 we're not using AM_INIT_GUILE_MODULE any more.
2028 * Makefile.in: Reneregated.
2030 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2032 Functions for finding variable bindings, grace à Tim Pierce.
2033 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2034 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2036 Get 'make dist' to work again.
2037 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2038 * Makefile.in: Regenerated, like a surry without a fringe on top.
2040 Changes for reduced Guile distribution: one configure script,
2042 * configure.in, configure: Removed.
2043 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2044 real configure script lives.
2045 * Makefile.in, scmconfig.h.in: Regenerated.
2047 * init.c: #include "script.h", to get prototype for script.c's
2050 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2052 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2053 scm_must_malloc, not raw malloc.
2055 * script.c (scm_compile_shell_switches): Dyke out debugging output
2058 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2060 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2062 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2063 system has them. Hope this is safe. Previously
2064 sys/timeb.h was included if HAVE_FTIME was defined or if
2065 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2066 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2068 * ioext.c (scm_setfileno): add missing third argument to
2069 scm_misc_error call.
2071 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2073 * eq.c (scm_equal_p): Correctly compare strings of different
2074 varieties. (Thanks to Tim Pierce.)
2076 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2078 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2079 #! block comment must occur on a line all by itself.
2081 Move most of the guts of shell command processing into libguile,
2082 so guile.c can be very small (and eventuallly auto-generated. (I
2083 mean, generated mechanically, not self-generated. Hmm.))
2084 * guile.c, script.c, script.h: New source files.
2085 * init.c (scm_boot_guile_1): Call scm_init_script.
2086 * libguile.h: #include "script.h".
2087 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2088 targets, for new executable.
2089 (libguile_la_SOURCES): Mention script.c.
2090 (modinclude_HEADERS): Add script.h.
2091 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2092 not dynamic linking is enabled. This is because we're generating
2093 executables now. Move CY_AC_WITH_THREADS call after those, so the
2094 values of cy_cv_threads_libs captures the libs chosen above.
2095 * Makefile.in, configure, aclocal.m4: Regenerated.
2097 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2098 We don't maintain this interface any more, and it just confuses
2101 * alloca.c: #include <scmconfig.h>, not <config.h>.
2102 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2103 it'll get included in disties.
2105 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2107 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2108 be distributed, because they confuse people.
2109 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2111 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2113 * configure.in: check for presence of gethostent (not present on
2114 OpenBSD by default).
2115 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2116 * configure, scmconfig.h.in: Regenerated.
2118 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2120 * backtrace.c (scm_backtrace): Split message string across
2121 newlines properly. GCC is more tolerant of this than other

2130 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2132 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2133 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2134 coop-threads.c.cygnus, coop-threads.h.cygnus.
2135 * configure.in: If we're using threads, include threads.o in
2137 * _scm.h, libguile.h: threads.h lives in this directory now.
2138 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2139 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2140 currently used, but brought along for information's sake.
2141 * ChangeLog-threads: log from old 'threads' directory.
2142 * Makefile.in, configure: Rebuilt.
2144 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2146 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2149 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2151 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2153 Merge GH interface library into libguile.

2155 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2156 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2157 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2159 (EXTRA_libguile_la_SOURCES): ... here.
2160 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2161 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2162 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2163 New variables, describing how to build the gh test programs.
2164 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2165 build the test programs, and we probably should have been linking
2166 libguile.la against them all along, to support AIX shared libs.
2167 Add cflags for threads to CFLAGS; add libs for threads to new
2168 variable THREAD_LIBS, used in Makefile.am.
2169 * ChangeLog-gh: log from old `gh' subdirectory.
2170 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2172 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2174 * acconfig.h: Undo change of Apr 9; including the definition of
2175 PACKAGE in the guile headers conflicts with applications' own
2177 * scmconfig.h.in: Regenerated.
2179 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

2188 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2190 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2191 have S_IFSOCK. This is the case under Ultrix.
2193 * posix.c (scm_status_exit_val, scm_status_exit_val,
2194 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2195 Ultrix versions of WIFSTOPPED, etc., which assume that their
2196 arguments are lvalues (hmm).
2198 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2200 * eval.c: Doc fixes.
2202 * throw.c: Doc fixes; rearranged.
2204 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.

2208 * acconfig.h: Added entry for PACKAGE.
2209 * scmconfig.h.in: Regenerated.
2211 Changes to work with automake-1.1n, which has better libtool support.
2212 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2213 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
2215 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
2217 * Makefile.in: Rebuild.
2219 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2221 * stime.c (scm_mktime): take an optional zone argument.
2222 (scm_localtime): check putenv return value.
2223 (scm_strftime, scm_strptime): moved from posix.c. move #include
2225 stime.h, posix.h: update prototypes.
2226 (bdtime2c, setzone, restorezone): new static procedures.
2227 (scm_mktime, scm_strftime): use them.
2228 (scm_strftime): don't call mktime before strftime. Use
2229 filltime for return value.
2230 (filltime): convert NULL zname to #f.
2231 (scm_strptime): return a count of characters consumed, not
2232 the remaining string.
2234 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2236 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
2237 (scm_mktime): likewise.
2239 Uncomment localtime and mktime.
2241 * configure.in: add AC_STRUCT_TIMEZONE.
2243 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2245 * stime.c (scm_init_stime): don't define ticks/sec.
2246 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2247 return value problem and is still portable.)
2249 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2251 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2252 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2253 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2254 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2255 cpp_err_symbols.c): Corresponding changes.
2256 * Makefile.in: Regenerated.

2261 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
2262 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
2263 * putenv.c: new file, from sh-utils 1.12.
2265 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2266 since allocation isn't for Scheme objects.
2267 (scm_putenv): copy strings before placing in the environment.
2269 * stime.c (scm_current_time): throw an error if time returns -1,
2270 instead of returning #f.

2274 * stime.h: prototypes updated.
2276 * stime.c (scm_time_in_msec): apparently unused, deleted.
2278 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2280 * configure.in: check for gettimeofday.
2282 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2283 which may be more usefully portable than a gettimeofday interface.
2285 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2287 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not

2298 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2300 * posix.c (scm_mknod): split the mode argument into type and perms
2301 arguments, like the extra fields returned by stat.
2303 * fports.c (scm_pipob): set the close, free and print procedures.
2304 (scm_close_pipe): new procedure.
2306 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2307 define them in boot-9.scm
2309 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2311 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
2312 wan't defined. Don't include fd.h.
2314 * Previously fd.h was regenerated whenever configure was run,
2315 forcing a couple of files to be recompiled.
2317 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
2318 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
2319 Check for _fileno as well as _file.
2321 * ioext.c: don't fd.h.
2322 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
2325 * Change the stratigy for getting information about errno
2326 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
2327 generating lists of symbols during the build process, which will
2328 not always work, include comprehensive lists in the distribution.
2329 To help keep the lists up to date, the "check_signals" and
2330 "check_errnos" make targets can be used.
2332 * configure.in: don't check for a command to extract errno codes.
2333 * Makefile.am: update file lists, remove errnos.list and errnos.c
2334 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
2335 check_errnos targets.
2336 (CLEANFILES): remove errnos.c and errnos.list, add
2337 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
2338 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
2339 * errnos.default: deleted.
2340 * cpp_signal.c: new file.
2341 * cpp_errno.c: renamed from errnos_get.c.
2342 * cpp_err_symbols, cpp_sig_symbols: new files.
2343 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
2344 * error.c (scm_init_error): #include cpp_err_symbols instead of
2346 * posix.c (scm_init_posix): don't intern signal symbols. #include
2349 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
2351 * strop.c (scm_i_index): allow the lower bound to be equal to the
2352 length of the string, so a null string doesn't always give an error.
2354 * posix.h: new prototypes.
2355 * posix.c (scm_status_exit_val, scm_status_term_sig,
2356 scm_status_stop_sig): new functions, as in scsh. They break down
2357 process status values as returned by waitpid.
2359 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
2361 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
2362 configure doesn't know about it.
2364 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2366 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
2368 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
2369 which defines C variables with global linkage.
2371 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2373 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
2376 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
2378 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
2379 has time to check why this doesn't work well with continuations.
2381 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
2383 * Fix shell syntax error; some shells won't tolerate
2384 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
2386 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2388 * posix.c (scm_uname): throw an error if uname fails instead
2391 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
2393 * error.c (err_head, scm_errno, scm_perror): obsolete procedures

2398 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2400 * acconfig.h: Removed PACKAGE.
2402 * scmconfig.h.in: Regenerated.
2404 * snarf.h: g++ says it's non-portable not to specify the first
2405 argument in a varargs declaration. I introduced the first
2406 argument by using preprocessor conditionals.
2408 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
2410 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
2411 (scm_freopen): use RO string macros for filename and modes.
2412 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.

2415 (scm_mknod): use RO string macros for path.
2417 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
2418 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
2420 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2421 use SCM_ROSTRINGP and SCM_ROCHARS.

2425 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
2428 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,

2430 support for byte vectors.
2432 * print.c (scm_iprin1): Limit number of vector elements printed
2433 according to pstate->length.
2435 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2437 * backtrace.c (scm_display_error_message): don't segv if message
2440 * error.h: prototype for scm_error_scm.
2442 * error.c (scm_error_scm): new procedure, reimplements scm-error
2443 in C and uses scm_error.
2445 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2447 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
2448 pointer to the Scheme variable read-hash-procedures and intern it
2449 in scm_init_read. Modify scm_read_hash_extend and
2450 scm_get_hash_procedure to use the pointer.
2452 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2454 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
2455 (SCM_KEYWORD_STYLE): defined.
2457 * read.c (scm_read_opts): add a keywords option. This isn't a
2458 boolean option, in case someone wants to add support for DSSSL
2460 Setup scm_keyword_prefix symbol.
2461 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
2463 I've left keyword support disabled by default, since it doesn't
2464 seem to break the module system and it gives R4RS standard behaviour.
2465 It can be reactivated with (read-set! keywords 'prefix).
2467 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2469 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
2470 before constructing arbiter.
2472 * eval.c (scm_m_define): Bugfix: Check that the object is a
2473 closure before setting the procedure property!
2475 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
2477 * ports.c: Removed `ungetc-char-ready?'.
2479 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
2481 * read.c (scm_init_read): intitialise scm_read_hash_procedures
2482 (idea from Mikael: make it a pair so scm_permanent object only
2484 (scm_read_hash_extend): don't call scm_permanent_object.
2485 (ideas from Mikael): if chr is already in the list, replace its
2486 procedure instead of appending it again. If proc is #f, remove
2488 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
2490 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
2492 * gdbint.c (gdb_read): update scm_lreadr usage.
2494 * load.h: update prototypes.
2496 * load.c (scm_primitive_load, scm_read_and_eval_x,
2497 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
2499 * read.h: add prototype for scm_read_hash_extend. Change args for
2502 * read.c (scm_read_hash_procedures): new variable.
2503 (scm_read_hash_extend): new procedure.
2504 (scm_get_hash_procedure): new procedure.
2505 (scm_lreadr): use scm_get_hash_procedure instead of an argument
2506 for extended # processing.
2507 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
2508 scm_read_token): remove case_i, sharp arguments. Change callers.
2510 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
2512 * read.h (SCM_N_READ_OPTIONS): increase to 3.
2513 (SCM_CASE_INSENSITIVE_P): define.
2515 * read.c: add case-insensitive option to scm_read_opts.
2516 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
2517 to determine whether to convert symbol case.
2518 (default_case_i): definition removed.
2519 * read.c (scm_read_token): if case_i, downcase ic before doing
2522 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2524 * configure.in: Added configuration option `guile-debug'.
2525 Configure with --enable-guile-debug if you want a bunch of extra
2526 functions used for debugging when developing Guile.
2528 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
2530 * procs.c (make-cclo): New undocumented debugging procedure: Make
2531 compiled closure with internal procedure PROC and length LENGTH.
2532 Only compiled if GUILE_DEBUG is defined.
2534 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
2536 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
2538 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
2540 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
2541 with 3 or more args internally to the evaluator.
2543 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2545 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
2546 with 3 or more args internally to the evaluator. This is mainly
2547 because we don't want to pass entry and exit points of the
2548 debug support twice, but it also seems to increase the speed of
2549 the evaluator for such calls (e. g. (+ 1 2 3)).
2551 * backtrace.c (scm_display_application): New procedure:
2552 display-application; Set fancy printing parameters individually
2553 for different types of display (backtrace, error, application).
2554 (These should of course be customizable!)
2556 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
2557 clear the CHECK-flags.
2559 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2561 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
2563 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2565 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
2566 from pairs with a GLOC in the car.
2568 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
2569 otherwise `symbol-hash' will behave badly.
2570 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
2571 we get segmentation fault!
2573 * symbols.c: Added #include "weaks.h". New functions:
2574 `builtin-bindings' and `builtin-weak-bindings'. (These will be
2575 moved to an extraneous library when we split libguile.)
2577 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2579 * filesys.c (scm_stat): stat now takes fport arguments too as
2580 documented in the manual.
2582 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2584 * debug.c (scm_single_step): Bugfix: Call continuation with
2585 scm_call_continuation instead of throwing to it.
2587 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
2589 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
2590 argument wasn't declared to be optional.
2592 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2594 * stime.c (scm_init_stime): Add feature "current-time".
2596 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
2598 * throw.h: prototype for scm_exit_status.
2599 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
2600 args to derive an exit status. Allows (quit) to work from a
2602 (scm_exit_status): new function.
2605 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2607 * eval.c (scm_deval): Removed some old code.
2608 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
2610 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
2613 * symbols.c (msymbolize): Bugfix: Must initialize property list to
2616 * procs.c: Introduce the existent C function scm_thunk_p at the
2617 Scheme level as well.
2619 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2621 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
2622 used from C to easily lookup the value of a symbol in the current
2625 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2627 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
2628 scm_init_unif in this file. This will also fix a previous problem
2631 * configure.in: Added AM_MAINTAINER_MODE
2633 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2635 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
2638 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
2640 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
2641 source files that are not always included in libguile but should
2642 have their dependencies calculated by automake. This variable is
2643 recognized by automake, no further magic is needed.
2644 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
2645 to deal exclusively with *.lo files, as it seems. The *.o files
2646 are built automatically when the corresponding *.lo file gets
2649 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
2651 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
2654 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
2656 * unif.c (scm_array_set_x): minor change to argument error checking.
2658 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
2660 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
2661 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
2662 They should only be included in the library at configure.in's
2664 (libguile_la_LDADD): Include the appropriate .lo files here.
2665 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
2666 so we know when to build them (and their .lo bretheren).
2667 * configure.in (LIBLOBJS): New substituted variable. We let
2668 configure decide which .o files to include in LIBOBJS, and then
2669 put the corresponding list of .lo files in LIBLOBJS. The latter
2670 is what we pass to libtool.
2671 * Makefile.in, configure: regenerated.
2673 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
2675 * symbols.c (scm_sysintern0): New function. Contains the core of
2676 old scm_sysintern but doesn't take a second value argument.
2677 (scm_sysintern): Now uses scm_sysintern0.
2678 (scm_sysintern_no_module_lookup): Renamed to
2679 scm_sysintern0_no_module_lookup and doesn't take a second value
2680 argument any longer.
2682 * symbols.h (scm_sysintern0: Added declaration.
2684 * options.c (scm_init_opts): Use scm_sysintern0 instead of
2685 scm_sysintern when interning option keys. Otherwise we risk
2686 destroying the values of already interned variables.
2688 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
2689 scheme-level boolean (use SCM_NFALSEP).
2691 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
2693 (scm_backtrace): New function. (C version of old function from
2694 boot-9.scm) Motivation: Make it possible to display backtraces
2695 without depending on boot-9.scm. (I'm uncertain if this
2696 motivation is good enough...)
2698 * root.h (scm_root_state): Add member the_last_stack_var.
2699 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
2701 * root.c (mark_root): Mark scm_the_last_stack_var.
2703 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
2706 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
2708 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
2709 1. mark_lazy_catch didn't mark the smob.
2710 2. Both functions above have standard variants:
2711 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
2712 free_lazy_catch --> scm_free0.
2714 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
2716 * throw.c (scm_internal_lazy_catch): New function.
2717 (scm_lazy_catch): Rewritten to use it.
2718 (scm_ithrow): Handle the new lazy catch representation.
2719 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
2720 that doesn't have a jmpbuf is a lazy catch clause.
2721 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
2722 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
2723 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
2725 (scm_init_throw): Register the new lazy-catch smob type.
2726 * throw.h (scm_internal_lazy_catch): decl for new function.
2728 * throw.c (scm_internal_catch): Doc fixes.
2730 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
2731 configure.in. Including this might cause problems if applications
2732 that link against libguile include their own copies of alloca, but
2733 if they're using autoconf, they should be adding libguile to LIBS
2734 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
2735 the copy in libguile, and things will be okay. (I think.)
2737 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2739 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
2741 strop.h: move prototypes too.
2743 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2745 * posix.c (scm_init_posix): don't intern EINTR since it's now done
2748 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
2749 etc. I deleted them from filesys.c long ago, but didn't
2750 notice they were here too (although ineffective since
2751 sys/stat.h wasn't included).
2753 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
2755 * eval.c: Don't define alloca in GCC case. gcc will automatically
2756 use __builtin_alloca if appropriate.
2758 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2760 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
2761 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
2762 that values of automatic variables are preserved. See comments
2763 for safe_setjmp for details.
2765 Change from Thomas Morgan:
2766 * variable.c: Include eq.h.
2767 (var_equal): New function.
2768 (variable_smob): Use var_equal as the discriminator for variables.
2770 * throw.c (s_throw): Remove extraneous declaration.
2772 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
2773 * eval.c: Add necessary CPP cruft to support that.
2774 * configure, Makefile.in, scmconfig.h.in: regenerated.
2776 Change from Thomas Morgan:
2777 * procprop.c (scm_procedure_properties): Convert the Scheme
2778 boolean returned by scm_procedure_p into a C boolean before using
2779 it as a condition for SCM_ASSERT.
2780 (scm_procedure_property): Likewise.
2782 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
2783 indications of Unixness.
2786 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2788 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
2790 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2792 * read.c (scm_lreadr): use scm_misc_error to improve one of the
2793 "unknown # object" error messages.
2795 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
2796 (scm_i_index) and declare it static. Add a 'direction' argument
2797 to indicate what way the search should go.
2798 (scm_i_index): throw out-of-range error instead of wrong-type-arg
2800 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
2801 strop.h: remove scm_i_index, scm_i_rindex prototypes.
2803 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2805 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
2807 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
2808 to avoid clash with various scsh forks.
2810 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
2812 The following two changes (ramap.c, throw.c) are motivated by the
2813 apparent unportability of forward declarations of static arrays of
2814 the form `static foo bar[];'.
2816 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
2817 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
2819 * throw.c (scm_throw): Moved above scm_ithrow.
2821 * options.h: Removed the extern declarations of scm_yes_sym and
2822 scm_no_sym since these are static.
2824 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2826 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
2828 * Makefile.am: remove AWK=@AWK@.
2829 Add a rule for generating errnos.list.
2830 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
2832 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
2833 don't extract errnos, just set a variable (avoids the
2834 need to recompile error.c just because configure is run.)
2836 * unif.h: update prototypes.
2837 * unif.c (scm_uniform_array_read,write): change the offset and
2838 length arguments to start and end, for consistency.
2840 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
2842 * ioext.h: update prototypes.
2843 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
2844 scm_read_line_x, it's a more general procedure using an
2845 interface from scsh. read-line and read-line! are now defined
2847 Note that the new read-line trims the terminator
2848 by default, previously it was appended to the returned string. An
2849 optional argument specifies how to process the terminator (scsh
2850 compatible). For the old behaviour: (read-line port 'concat).
2851 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
2852 returns a pair, but is converted to multiple values if the scsh
2855 socket.h: update prototypes.
2856 * socket.c (scm_recvfrom): for consistency with other procedures,
2857 take start and end as separate optional arguments.
2858 (scm_recv, scm_recvfrom): don't allow the second argument
2859 to be a size, only a buffer. Change the scheme names to
2860 recv! and recvfrom!. Don't return the buffer.
2862 * ioext.h, posix.h: move prototypes too.
2863 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
2864 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
2865 "read.h" and "unif.h".
2866 * ioext.c: include "chars.h"
2868 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
2870 * dynl.c: The dynamic linking and module registration functions
2871 are now defined even when dynamic linking is not available for the
2872 host system. Some of their functionality can be done without
2873 dynamic linking; when it's really needed, they throw errors.
2875 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
2877 * configure.in: Only define DYNAMIC_LINKING when one of the system
2878 dependent functions is detected.
2879 * dynl.c (scm_dynamic_func): New function to get the address of a
2880 function in a dynamic object.
2881 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
2882 produced by scm_dynamic_func as the thing to call.
2884 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
2886 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
2887 (scm_register_module_xxx, scm_registered_modules,
2888 scm_clear_registered_modules): New functions.
2890 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
2892 * symbols.c (scm_sysintern): Renamed to
2893 scm_sysintern_no_module_lookup.
2894 (scm_sysintern): New function to take the place of the old
2895 scm_sysintern. It uses the current toplevel lookup closure to give
2896 the symbol its value. This is a temporary hack to put packages
2897 like gtcltk into their own module.
2898 (scm_can_use_top_level_lookup_closure_var): New variable to tell
2899 us whether `scm_top_level_lookup_closure_var' has been initialized
2901 * eval.c (scm_init_eval): Set it.
2903 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
2905 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
2906 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
2908 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
2910 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
2911 scm_sys_dup): deleted: FD capability will be added to other
2913 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
2914 scm_fd_free, fd_smob, scm_intern_fd.
2915 (scm_open): renamed from scm_sys_open. Return a port instead of
2916 an FD object. Make the mode argument optional.
2917 (scm_sys_create): deleted, it's just a special case of open.
2918 (scm_init_filesys): move interning of constants O_CREAT etc.,
2919 here (were previously using SCM_CONST_LONG macro).
2920 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
2922 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
2923 include "fports.h" and <stdio.h>
2924 (scm_stat, scm_select): don't support FD objects.
2926 * error.h: adjust scm_syserror_msg prototype.
2927 * error.c (scm_syserror_msg): take an extra argument for errno.
2928 Using the global value didn't always work, since it could be
2929 reset by procedure calls in the message or args arguments.
2931 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
2932 I don't understand why the check was there (and what about the
2935 * strop.c (scm_string_copy): allow shared substrings to be copied.
2937 * unif.h: corresponding change to prototypes.
2938 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
2939 recognize two new optional arguments: offset and length. Allow
2940 the port argument to be an integer (file descriptor, for scsh).
2941 Include <unistd.h> for "read" prototype.
2943 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2945 * socket.c: don't include filesys.h.
2947 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
2949 * Makefile.am: add AWK=@AWK@ (?)
2951 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
2953 Add a rule to generate errnos.c from errnos.
2954 * error.c (scm_init_error): include errnos.c.
2955 * errnos_cnvt.awk: new file, converts the list of errno codes to
2957 * errnos_get.c: new file.
2958 * errnos.default: new file, contains errnos to try if they can't
2959 be extracted from errno.h.
2960 * configure.in: if using GCC, try and extract errno codes from
2964 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
2966 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
2967 * Makefile.am: Made libguile into a libtool library.
2968 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
2969 Set libtool_libs to indicate that libguile is a libtool library.
2970 See guile/ChangeLog for details.
2971 * .cvsignore: ignore "*.lo", the libtool library objects.
2973 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2975 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
2976 use htons in getservbyport argument.
2978 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2980 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
2981 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
2984 * objprop.c (scm_object_property): No need to take the CDR of the
2985 value returned by scm_object_properties, since Aug 20 change.
2987 * configure.in: When checking for struct linger, #include
2988 <sys/types.h> as well as <sys/socket.h>. I've never known
2989 <sys/types.h> to cause any portability problems, and Solaris's
2990 <sys/socket.h> needs it.
2991 * configure: Rebuilt.
2993 I think the Sun compiler has chosen a perverse way to interpret
2994 ANSI declarations combined with K&R definitions. We'll
2995 appease it a little bit. But when it invades France, we fight.
2996 * print.c (scm_iprlist): Change 'tlr' argument to an int.
2997 * print.h (scm_iprlist): Here too.
2998 * numbers.c (scm_divbigdig): Change definition to match
2999 declaration in numbers.h.
3000 * unif.c (scm_makflo): Change definition to match declaration in
3003 * init.c (scm_boot_guile): Don't return the value of
3004 scm_boot_guile_1. This function doesn't return a value;
3005 scm_boot_guile_1 doesn't return a value (or return at all).
3007 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3010 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3011 compile. I have a feeling this function is a bad idea anyway ---
3012 one should always test for features, not systems.
3014 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3015 semicolons. Only pure luck kept this from being noticed earlier.
3017 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3019 * socket.c (scm_recvfrom): Added missing semicolon.
3021 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3023 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3024 the buffer and start and end positions for scsh networking
3027 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3029 * configure.in: Revert previous change to this file; the problem
3030 is due to transient automake weirdness.
3031 * configure: Rebuilt.
3033 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3034 PLUGIN/guile.libs. configure generates the latter from the former.
3035 * Makefile.in: Rebuilt.
3037 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3038 need this if we install scripts, like guile-snarf.
3039 * configure: Rebuilt.
3041 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3043 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3045 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3047 * socket.c (scm_addr_vector): fix faulty scm_listify.
3049 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3051 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3052 style block comment is no longer considered an error.
3054 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3056 * PLUGIN/guile.libs.in: New file.
3057 * PLUGIN/guile.libs: Removed from repository.
3058 * configure.in: Create PLUGIN/guile.libs from
3059 PLUGIN/guile.libs.in. This is for including additonal libraries
3060 needed for dynamic linking.
3061 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3062 instead of PLUGIN/guile.libs.
3064 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3066 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3068 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3069 occurrences of the given element from the list, not just the
3070 first. This is how the Emacs Lisp functions behave, how the
3071 analogous Common Lisp functions behave, and (I believe) how the
3072 older Maclisp functions worked. I realize that this change may
3073 break code, but it seemed better to break it before the Guile
3076 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3077 Their prototypes were already present in gc.h, but they weren't
3079 (scm_init_storage): Initialize scm_protects.
3080 * root.c (scm_protects): New element of scm_sys_protects.
3082 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3084 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3086 * libguile.h: Added #include "libguile/net_db.h".
3088 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3089 30 change. That file is only meant for communication between the
3090 configuration process and load.c. If code linked against libguile
3091 wants to get at the paths mentioned in libpath.h, it can call
3092 functions declared in load.h.
3094 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3096 * libguile.h: Removed #include "libguile/fdsocket.h"
3098 * net_db.c: Added #include <sys/socket.h>.
3100 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3102 * filesys.c (scm_input_waiting_p): use select in preference to
3103 FIONREAD, since the latter doesn't detect EOF.
3104 Throw error if neither select nor FIONREAD available.
3106 * socket.c (scm_connect): take a port, not a fd object.
3107 (scm_fill_sockaddr): throw an error if fam is not recognised.
3108 (scm_bind): use scm_fill_sockaddr.
3109 (scm_listen): take a port, not a fd object.
3110 (scm_accept): take and return a port. return #f in the car if
3111 address can't be got
3112 (scm_sock_fd_to_port): new procedure.
3113 (scm_socket): use scm_sock_fd_to_port.
3114 (scm_addr_vector): throw error if unrecognised address type.
3115 take an extra argument with the calling procedure name.
3116 (scm_getsockname): take a port. return #f if address can't be got.
3117 (scm_getpeername): take a port. return #f if address can't be got.
3118 (scm_recvfrom): take a port. return #f for address component if can't
3120 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3121 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3123 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3125 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3126 use separate data pointers, to allow them to be designed
3127 independently and reused.
3128 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3129 Renamed from catch_body, catch_handler, and uncaught_throw; made
3131 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3133 (scm_catch): Use the above.
3134 (scm_throw): Don't bother printing a message for an uncaught
3135 throw; we establish a default handler in init.
3136 * throw.h (scm_internal_catch): Prototype updated.
3137 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3139 (struct scm_body_thunk_data): New structure, used as data
3140 argument to scm_body_thunk.
3141 * init.c (struct main_func_closure): New structure, packaging up
3142 the data to pass to the user's main function.
3143 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3144 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3145 scm_internal_catch to establish a catch-all handler, using
3146 scm_handle_by_message. This replaces the special-case code in
3148 (invoke_main_func): Body function for scm_internal_catch; invoke
3149 the user's main function, using the main_func_closure pointer to
3150 decide what to pass it.
3151 * root.c (struct cwdr_body_data): Remove handler_proc member.
3152 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3153 (cwdr_handler): Removed.
3155 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3157 * socket.h (SCM_P): update bind prototype.
3158 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3159 include "feature.h".
3160 (scm_socket): return a port, not a file descriptor object.
3161 include "fports.h" and <unistd.h>
3162 (scm_bind): take a port, not a file descriptor object.
3163 take an extra argument for address args.
3165 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3166 INADDR_NONE, INADDR_LOOPBACK.
3168 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3170 * init.c: include net_db.h and not fdsocket.h.
3171 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3173 * Makefile.am: corresponding changes.
3174 * socket.h: renamed from fdsocket.h, fix names.
3175 * net_db.h: renamed from socket.h, fix names.
3176 * socket.c: renamed from fdsocket.c.
3177 remove _sys from procedure names.
3178 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3179 add "socket" to features list.
3180 * net_db.c: renamed from socket.c.
3181 remove _sys from procedure names.
3182 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3183 add "net-db" to features list.
3184 include "net_db.h". don't include <sys/socket.h> or
3187 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3189 * tags.h (scm_tags): Removed comma at end of last enumerator.
3191 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3193 Don't use GCC extensions to allocate space for debugging frames.
3194 (Here he goes again! Why do we put up with this?!)
3195 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3196 an scm_debug_info structure, not an in-line array of them. Add
3197 'info' member, to say how many vect elements we've used, for eval
3199 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3200 a new variable debug_info_end to mark the end of vect, instead of
3201 the address of the 'info' pointer itself.
3202 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3203 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3204 (SCM_APPLY): Explicitly allocate space for debug.vect.
3205 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3206 * stacks.c: Adjusted for new debug frame structure.
3207 (RELOC_INFO, RELOC_FRAME): New macros.
3208 (stack_depth, read_frames): Use them, and new scm_debug_frame
3209 element 'info', instead of magically knowing that eval frames have
3210 an info pointer sitting after vect.
3211 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3213 (scm_init_stacks): Formatting tweaks.
3215 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3217 Give GCC more control flow information, so it can be sure that
3218 variables aren't used uninitialized.
3219 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3220 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3221 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3222 scm_misc_error): Tell GCC that these functions never return.
3223 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3224 out the field type, call abort if SCM_ASSERT returns, to placate
3226 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3227 scm_wta ever returns. We can't handle this case anyway, and this
3228 gives the optimizer more information.
3229 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3230 scm_wta ever returns.
3232 In some cases, the code is fine, but GCC isn't smart enough to
3233 figure that out; this usually happens when one variable is only
3234 initialized and used when a particular condition holds true, and
3235 we know that condition will never change within a given invocation
3236 of the function. In this case, we simply initialize the variables
3237 to placate the compiler, hopefully to a value which will cause a
3238 crash if it is ever actually used.
3239 * print.c (scm_iprin1): Initialize mw_pos.
3240 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3241 * throw.c (scm_ithrow): Initialize dynpair.
3242 * unif.c (scm_uniform_vector_ref): Initialize cra.
3243 * struct.c (init_struct): Initialize prot.
3244 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3246 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3247 if EXPR contains no expressions.
3249 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3251 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3252 cause an infinite loop (???). So much for the algebraic
3253 equivalency of variable-sized arrays and alloca...
3255 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3257 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3258 a SCM boolean, not a C boolean.
3260 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3262 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3263 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3264 rules for raising scm_mtrigger. Previously, unfortunate but not
3265 unlikely circumstances could result in almost constant invokation
3266 of the gc. Now, this situations should be less likely, but they
3267 are not prevented completely.
3269 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3271 * numbers.c (scm_fuck): Procedure removed; looks like old test
3273 * numbers.h: Prototype removed.
3275 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3277 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3278 array to a pointer, to match my Nov 21 change in eval.c.
3280 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3282 * libguile.h: Added #include "libguile/backtrace.h", #include
3283 "libguile/stacks.h".
3285 * strings.c (scm_string scm_make_string scm_string_ref
3286 scm_string_set_x scm_string_equal_p scm_string_append):
3287 Bugfix according to scm patch from Aubrey Jaffer:
3288 Corrected long-standing
3289 (not (eqv? (integer->char 128)
3290 (string-ref (make-string 1 (integer->char 128)) 0)))
3291 bug found by John Kozak <jk@noontide.demon.co.uk>.
3293 * strports.c, strports.h: Make scm_eval_0str return the value of
3294 the last expression evaluated (previously, it returned void).
3296 * strports.c, strports.h: New function: scm_read_0str. Does what
3299 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3301 * simpos.c (scm_getenv): return #f if string can't be found in the
3302 environment instead of throwing an exception, for compatibility
3303 with numerous other systems.
3305 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3307 * Makefile.am (.c.x): Use guile-snarf.
3308 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
3310 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
3312 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3314 * backtrace.c (scm_display_error_message): Made non-static, and
3315 renamed from display_error_message.
3316 * backtrace.h (scm_display_error_message): Added extern decl.
3317 * throw.c (uncaught_throw): Use it to display the error message.
3319 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
3321 * inet_aton.c: Use #if 0, not #ifdef 0.
3323 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
3325 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
3326 to convert the returned value.
3327 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
3328 the offset argument.
3330 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3332 Add new interface to catch/throw, usable from C as well as
3334 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
3335 (scm_internal_catch): New function, replaces...
3336 (scm_catch_apply): Deleted.
3337 * throw.c (scm_catch_apply): Deleted; replaced with a more general
3338 mechanism which is a bit more code, but can be used nicely from C
3339 and implement the Scheme semantics as well.
3340 (scm_internal_catch): This is the replacement; it's named after
3341 the analogous function in Emacs.
3342 (scm_catch): Reimplemented in terms of the above.
3343 (struct catch_body_data, catch_body, catch_handler): New
3344 functions, used by scm_catch.
3345 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
3346 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
3347 support for new cwdr.
3349 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
3352 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
3354 * acconfig.h: Added DYNAMIC_LINKING symbol.
3355 * configure.in: Add option and checks for dynamic linking.
3356 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
3357 dynl.h: New files for dynamic linking support.
3358 * Makefile.am (libguile_a_SOURCES):
3360 (modinclude_HEADERS): Added "dynl.h".
3361 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
3363 * init.c (scm_boot_guile_1): Call
3364 scm_init_dynamic_linking to initialize dynamic linking support.
3366 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
3368 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
3369 (as we Schemers say). It needs to be global, so that I can tweak
3370 it for the proper operation of unexec.
3371 (scm_boot_guile_1_live): New variable, see above.
3373 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
3375 * guile-snarf.sh: Removed.
3376 * PLUGIN/guile.libs: Added dependency for -lm.
3377 * acinclude.m4: Renamed from aclocal.m4.
3378 * PLUGIN/greet: Removed.
3379 * Makefile.am, aclocal.m4: New files.
3380 * configure.in: Updated for Automake.
3382 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
3384 * eval.c (scm_definedp): Use top_level_lookup_closure_var
3385 and not top_level_lookup_thunk_var.
3387 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
3389 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
3391 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
3393 * eval.c (scm_definedp): Incompatibly changed to be a builtin
3394 Scheme function, instead of syntax. Single argument is now a
3397 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3399 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
3400 scm_ra_divide): Properly terminate statements passed as arguments
3401 to IVDEP macros. (Thanks to Bernard Urban.)
3403 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
3404 with non-constant sizes. (Thanks to Bernard Urban.)
3406 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3408 It's an "eval closure", not an "eval thunk." A thunk is a
3409 function of no arguments.
3410 * root.h (struct scm_root_state): Renamed
3411 top_level_lookup_closure_var from top_level_lookup_thunk_var.
3412 (scm_top_level_lookup_closure_var): Renamed from
3413 scm_top_level_lookup_thunk_var.
3414 * root.c (mark_root): Uses changed.
3415 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
3416 * init.c (scm_start_stack): Uses changed.
3417 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
3418 Change scheme-visible name to *top-level-lookup-closure* from
3419 *top-level-lookup-thunk*.
3421 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
3423 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
3424 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
3426 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
3428 * gc.c (struct scm_heap_seg_data): Doc fixes.
3430 * gc.c (scm_gc_sweep): Empty all segments' freelists before
3431 sweeping. Then, prepend each segment's free cells to its
3432 freelist, rather than wiping out the old value. (Thanks to Marius
3435 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
3436 scm_check_freelist, scm_debug_newcell): New functions and
3437 variables, for debugging freelist problems.
3438 * pairs.h (SCM_NEWCELL): New debugging version added.
3439 * gc.h (scm_debug_newcell): Added extern declaration, used by
3440 debugging version of SCM_NEWCELL.
3442 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3444 On some systems <libc.h> conflicts with <unistd.h>, and should not
3445 be #included at all.
3446 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
3447 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
3448 * configure.in: Call it.
3449 * posix.c, filesys.c: Use its results to decide whether or not to
3451 * configure, scmconfig.h.in: Rebuilt with autoconf and
3454 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
3456 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
3457 pointer to the stdio stream before calling scm_setbuf0, so the
3458 latter will be able to retrieve it. I'm surprised this didn't
3459 segfault earlier. (Thanks to Christopher Lee.)
3461 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3463 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
3466 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3468 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
3469 number of stack narrowing specifier pairs. The first specifier in
3470 a pair controls inner border, the second the outer border. A
3471 number means cut that number of frames, a procedure object means
3472 cut until that object is found in operator position in a frame.
3474 * root.c (cwdr): Bugfix.
3476 * read.c: Recording of positions disabled by default.
3478 * procs.c (scm_closure_p): New function.
3480 * posix.c (scm_tmpnam): New function.
3482 * load.c: Added #include "throw.h".
3483 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
3486 * load.c, load.h (scm_read_and_eval_x): New function.
3488 * eval.c: Renamed debug option "deval" to "debug".
3490 (scm_eval_x): `eval!' is no longer accessible from the scheme
3491 level. Motivation: We can't allow operations which introduce
3492 glocs into the scheme level. Guile's type system can't handle
3493 these as data. Use `eval' or `read-and-eval!' as replacement.
3495 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
3496 SCM_CONSP since this is a macro!; Set vframe.prev to
3497 scm_last_debug_frame instead of 0. In this way we can look
3498 "above" the virtual start stack frame if we wish.
3499 (scm_debug_hang): New function: Useful for debugging Guile in
3500 certain tricky situations. Will probably be removed later...
3502 * debug.h: Changed semantics of debug option "backtrace". This
3503 option now only indicates whether we want automatic backtrace at
3506 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3508 * ports.c: #include "filesys.h"
3509 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
3511 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
3512 Motivation: This is system specific code which is related to file
3513 I/O. It also may use select. Added code by Gary Houston to
3514 detect presence of character in stdio buffers.
3516 * libguile.h: #include "libguile/libpath.h"
3518 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
3519 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
3520 SCM_SITE_DIR; Install libpath.h among the other include files.
3522 * load.c, load.h (scm_sys_package_data_dir): New function.
3524 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3526 * stacks.h: Bugfix: Don't use tail-array length field as stack
3527 length field! This screwed GC.
3529 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3531 * _scm.h: Added #ifndef around definition of macros min and max.
3533 * __scm.h: Added hooks for threads to plugin to in ints protection
3534 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
3535 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
3536 the main code in these macros duplicated and spread over multiple
3537 files. Renamed SCM_THREADS_SWITCHING_CODE ->
3538 SCM_THREAD_SWITCHING_CODE.
3540 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
3542 * snarf.h: New file.
3543 * guile-snarf.sh: New file.
3544 * Makefile.in (inner_h_files): Added snarf.h
3545 (ancillary, install, uninstall, distclean): Added actions for
3547 (.c.x): Use guile-snarf.
3548 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
3549 (gen_c_files): Note that these depend on guile-snarf.
3550 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
3551 now in "snarf.h". Added #include "snarf.h" to get them.
3552 * libguile.h: Added #include "snarf.h".
3553 (Patches applied and tweaked by Jim Blandy.)
3555 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
3557 * socket.c: Use K&R style declaration for 'close'; the GNU coding
3558 standards suggest against providing prototypes for system
3559 functions. Thanks to Greg Troxel.
3561 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3563 * strports.c (scm_eval_0str): New function.
3564 #include "read.h", to get prototype for scm_read.
3565 * Makefile.in (strports.o): Update dependencies.
3566 * strports.h: New prototype.
3568 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
3569 scheme name from "int?" to "integer?". It seems to do the job.
3570 * numbers.h: Rename prototype too.
3571 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
3574 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
3575 scm_num_eq_p): Rename these according to R4RS conventions: call
3576 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
3577 to making libguile R4RS compliant without ice-9...
3579 * load.c (scm_sys_search_load_path): Search for files under all
3580 extensions listed in the %load-extensions variable. If FILENAME
3581 is absolute, return it unchanged, without searching the load path.
3582 (scm_loc_load_extensions): New variable, pointing to
3583 %load-extensions' value cell.
3584 (scm_init_load): Initialize it, and the value it points to.
3585 (scm_primitive_load_path): Improve error reporting.
3587 * load.c (scm_loc_load_hook): New variable, pointing to value cell
3588 of new Scheme variable %load-hook.
3589 (scm_primitive_load): Apply %load-hook to filename.
3591 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
3593 * configure.in: add tests for figuring out whether buffered data
3594 is available in a FILE structure, which is needed by char-ready.
3596 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
3599 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
3600 exceptions using misc_error instead of syserror. It seems a bit
3601 odd to throw an exception if a string can't be found in the
3602 environment, but it's consistent with open-file, stat etc.
3603 (simpos.h): remove sys_ from getenv.
3605 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
3606 occurs, throw an error instead of returning errno. Return value
3608 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
3610 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
3612 * filesys.c (scm_stat2scm): derive file type and permissions from
3613 the stat mode and append them to the returned vector.
3614 There isn't much overhead in doing this and it avoids the need to
3615 work with S_IRUSR et al. in Scheme.
3616 Define symbols scm_sym_regular etc.
3617 (scm_init_filesys): don't intern S_IRUSR etc.
3619 * load.c: change s_try_load and s_try_load_path to s_primitive_load
3620 and s_primitive_load_path.
3622 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
3624 * error.h: don't declare error symbols. prototype for scm_misc_error.
3626 * stackchk.c (scm_stack_overflow_key): defined here instead of in
3629 * error.c: use SCM_SYMBOL to set up error keys.
3630 scm_misc_error: new procedure.
3632 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3634 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
3635 between `#!' and `!#' is ignored.
3636 (skip_scsh_block_comment): New function.
3638 * feature.c (scm_set_program_arguments): New argument, FIRST.
3639 * feature.h: Update prototype.
3640 * init.c (scm_boot_guile_1): Pass new argument to
3641 scm_set_program_arguments.
3643 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3645 * init.c (scm_start_stack): Don't initialize scm_progargs here.
3646 (scm_boot_guile): Call scm_set_program_arguments here, later than
3647 the old initialization.
3649 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
3650 initialization procedure.
3651 - Delete in, out, err arguments; there are other perfectly good
3652 ways to override these when desired.
3653 - Delete result argument; this function shouldn't ever return.
3654 - Rename init_func argument to main_func, for less confusion.
3655 - Delete boot_cmd argument; main_func is more general.
3656 -Add 'closure' argument, to help people pass data to main_func
3657 without resorting to global variables.
3658 - Abort if reentered; don't bother returning an error code.
3659 - Call scm_init_standard_ports to set up the default/current
3660 standard ports; no need to pass them to scm_start_stack.
3661 - Remove code to evaluate the boot_cmd, and start the repl; let
3662 the user do something like that in main_func if they want.
3663 - Remove code to package up a return value; main_func can do any
3665 - Call exit (0), instead of returning.
3666 (scm_start_stack): Don't initialize the I/O ports here; that's
3667 weird. Delete in, out, err arguments. Move guts to
3668 scm_init_standard_ports, scm_stdio_to_port.
3669 (scm_init_standard_ports): New function, to set up current and
3670 default standard ports.
3671 (scm_start_stack, scm_restart_stack): Make these static.
3672 * init.h (scm_boot_guile): Adjust declaration.
3673 (scm_start_stack, scm_restart_stack): Remove externally
3674 visible declarations for these.
3675 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
3677 * fports.c (scm_stdio_to_port): New function. Its guts used to be
3678 written out several times in scm_start_stack.
3679 * fports.h: New declaration for the above.
3681 * feature.c (scm_set_program_arguments): New function.
3682 * feature.h: New declaration for the above.
3684 * ports.c: Formatting tweak.
3686 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
3688 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
3689 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
3690 for obtaining the address of a car or cdr field. Motivation:
3691 &SCM_CXR make assumptions about the internal structure of the
3694 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
3695 Motivation: see SCM_CXRLOC.
3697 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
3698 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
3699 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
3700 Motivation: Safer use. Some other macros are defined in terms of
3701 these operations. If these are defined using the SCM_SETCXR
3702 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
3703 to inefficiency and an <e1> with side-effects could potentially
3704 break. Also, these particular operations are heavily utilized in
3705 the garbage collector. In unoptimized code there will be a
3708 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
3709 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
3710 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
3711 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
3712 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
3713 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
3714 vports.c: Cleaned up use of pairs: Don't make any special
3715 assumptions about the internal structure of selectors and
3716 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
3717 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
3718 (Among other things, this change makes it easier to build Guile
3719 with certain compilers which have problems with casted lvalues.)
3721 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3723 * stacks.c: Improve selection of relevant stack frames when making
3724 a stack object. Introduce one level of indirection in the stack
3725 object to make it possible to "narrow" to a certain region of the
3726 stack. This facilitates making use of more clever algorithms (not
3727 implemented) for selecting relevant frames and gives a cleaner
3728 design since selection of frames can be done independently of
3729 extraction of frames from the real stack.
3730 (scm_stack_id): Also take #t as argument which means look at
3733 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
3734 Turn n_tail into an integer directly representing current number
3735 of frames in stack. Add field tail.
3737 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
3739 * debug.c (scm_make_memoized): Made it available at scheme level.
3740 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
3741 SCM_NIMP before applying heavier predicates in argument checking.
3742 (scm_local_eval): Also take memoized object as argument.
3744 * backtrace.c (scm_display_error): Just a safety measure: Stacks
3745 aren't created with zero length, but should such a strange
3746 creature suddenly turn up...
3748 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
3750 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
3751 `del', for the sake of C++ compilers. (Patch applied by JimB.)
3753 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
3755 * variable.c (scm_make_variable): Make the name hint optional, as
3757 (anonymous_variable_sym): Renamed from variable_sym. All uses
3760 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
3761 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
3762 of scm_primitive_load_path was also changed to
3763 "primitive-load-path", from "%try-load-path". Callers changed.
3764 We'd like to respect the convention that a function named
3765 "try-mumble" should behave just like the function called "mumble",
3766 but return #f instead of signalling some error.
3767 * load.h: Rename prototypes.
3769 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3771 * print.c (make_print_state, grow_print_state), print.h: Modified
3772 the print state representation: Don't use a tail array for
3773 recording of circular references. Resizing of the print state
3774 structure invalidates the print state pointer. To avoid passing
3775 around an indirect print state reference to all printing
3776 functions, we instead let the print state reference a resizable
3779 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
3781 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
3782 Don't crash when passed an improper list terminated by a
3783 non-immediate value.
3785 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
3787 Allocate data for structures on an eight-byte boundary, as
3788 required by the tagging system.
3789 * struct.c (alloc_struct): New function.
3790 (scm_make_struct, scm_make_vtable_vtable): Call it.
3791 * struct.h (scm_struct_n_extra_words): Bump to 3.
3792 (scm_struct_i_ptr): New "field".
3793 * gc.c (scm_gc_sweep): When we need to free the data, use the
3794 information stored by alloc_struct to find the beginning of the
3795 block allocated to the structure, so we can free it.
3797 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3799 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
3802 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
3803 (scm_debug_info): New member: id.
3805 * stacks.c: Stacks are now represented as structs; Stacks have an
3806 id given to them by `start-stack'.
3807 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
3809 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
3810 Changed stack representation.
3812 * debug.c (scm_procedure_name): Try procedure property `name' for
3813 compiled closures aswell.
3815 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
3817 * eval.c: scm_i_name moved to gsubr.c
3818 (scm_m_define): Record names of all kinds of procedure
3819 objects. (Earlier, only closures were recorded.)
3821 * procprop.h: Added declaration of scm_i_name.
3823 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
3824 (scm_make_gsubr): Record names of compiled closures.
3826 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3828 * debug.c, debug.h: Removed obsolete code.
3830 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
3831 stacks.c: Renamed regs --> scm_contregs.
3833 * print.c (scm_free_print_state): Cleanup print state before
3834 returning it to pool. It is better to do it here than in
3835 scm_prin1 since scm_prin1 is called often.
3837 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
3838 s_set_source_property_x): Check that first argument is a pair or a
3841 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
3842 scm_i_line, scm_i_column and scm_i_breakpoint global.
3844 * init.c: Added #include "backtrace.h" and #include "stacks.h".
3845 (scm_boot_guile_1): Added calls to scm_init_backtrace and
3848 * debug.h: Added debug object smob declaration and macro
3851 * configure.in: Build with backtrace.o and stacks.o if debug
3854 * Makefile.in: Added entries for new files: backtrace.c,
3855 backtrace.h, stacks.c and stacks.h.
3857 * symbols.c (scm_sym2ovcell): Fixed documentation.
3859 * _scm.h (min, max): Added.
3861 * async.c: Moved `min' macro to _scm.h.
3863 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
3864 SCM_BACKTRACE_INDENT.
3866 * eval.c: Added new debug options `maxdepth' and `indent'.
3868 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
3870 * print.h: Added selector SCM_PRINT_STATE.
3872 * print.c: New functions: scm_make_print_state,
3873 scm_free_print_state.
3875 * print.h: Added declarations for scm_make_print_state,
3876 scm_free_print_state.
3878 * debug.c (scm_m_start_stack): New acro.
3880 * debug.h: Small cleanup.
3882 * init.c (scm_boot_guile_1): Moved scm_init_debug below

3910 More prototype-related changes from Marius Vollmer:
3911 * gdb_interface.h: Wrapped header file in #ifdef/#endif
3912 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
3913 * ports.h (ptobfuns): Added prototypes. This means some casting in
3915 * fports.c: Added casts for initializations, since the functions
3916 are defined to take FILE * as their stream argument, not SCM.
3917 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
3918 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
3919 to `char *str_data' to conform to prototype.
3921 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
3923 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
3925 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
3927 * stime.c, stime.h: use SCM_P method.
3929 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
3931 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
3932 be given at least two arguments. Insist that lst's last element
3933 be a list, but don't make any requirements of its predecessors.
3935 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
3937 * eval.c (scm_nconc2last): Revert last change; there seems to be
3938 other stuff going on here.
3940 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
3942 * eval.c (scm_nconc2last): Make sure that each element of lst
3943 (which is a list of argument lists, except for the tail) is a
3944 proper list, i.e., finite and terminated by '().
3946 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
3948 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
3951 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
3952 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
3955 * vectors.c (scm_make_vector): Fill vectors with the undefined
3956 value, to help make Guile Scheme code more portable to other
3959 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
3960 * symbols.h, tags.h: Doc fixes.
3962 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
3964 * async.c (scm_take_signal): Doc fixes.
3966 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
3968 * numbers.c (scm_divbigint): When the remainder is zero, we don't
3969 want to subtract it from the modulus; we just want to leave it
3972 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
3974 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
3977 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
3979 * throw.c (scm_catch_apply): Finished implementation of
3982 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
3984 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
3986 (scm_init_filesys): set "i/o-extensions" feature.
3989 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
3991 * Makefile.in (root.o): Correct dependencies.
3993 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
3995 * Makefile.in: Added dependency entry for root.o.
3997 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
3998 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4000 * init.c (scm_start_stack): Set initial root continuation number
4003 * procs.c: New function: scm_thunk_p.
4005 * procs.h: Added declarations of scm_thunk_p.
4007 * root.c: Renamed `call-with-new-root' -->
4008 `call-with-dynamic-root'.
4009 (cwdr): Removed allocation of new root state. This should be done
4010 separately by use of scm_make_root.
4011 (scm_apply_with_dynamic_root): New function: Does what it
4012 sounds like. Needed when spawning threads.
4014 * root.h: Added member last_debug_frame to root state.
4015 Added #include "libguile/debug.h"
4017 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4018 arguments. The motivation is that code in root.c needs catch
4019 functionality, and we want to avoid code duplication.
4020 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4021 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4022 handlers that run without popping the stack into the dynwind
4025 * throw.h: Added prototypes for scm_catch_apply and
4028 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4030 * root.h (scm_root, scm_set_root): Decouple thread support details
4031 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4032 SCM_SET_THREAD_LOCAL_DATA.
4034 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4035 and tortoise scanning loop.
4037 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4039 * Makefile.in: Rebuild dependencies.
4041 * libguile.h: #include "libguile/print.h" before "smob.h", since
4042 the latter uses the print_state structure.
4044 * throw.c (scm_ithrow): Use the correct variable when checking to
4045 see if a given element of scm_dynwinds is a valid catch.
4047 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4048 structure, abort; don't just silently ignore the garbage.
4050 * _scm.h: #include "print.h" here, since it seems to be used just
4052 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4053 strports.c, unif.h: Don't #include "print.h".
4055 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4057 * feature.h (scm_loc_features): Removed external declaration.
4058 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4060 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4062 * feature.c (scm_init_feature): Added threads feature (needs to be
4063 initialized here, since features doesn't exist when
4064 scm_init_threads is called).
4066 * libguile.h: Added #include "libguile/../threads/threads.h".
4067 (This is a kludge to get thread support working. This should be
4070 * configure.in, acconfig.h: Added flags for thread support.
4072 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4075 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4076 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4079 * _scm.h: Added conditional #include "threads.h"
4081 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4082 SCM_THREADS_SWITCHING_CODE.
4084 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4085 allocate the basic dynamic root object.
4086 (scm_boot_guile): Added call to scm_init_root.
4088 * root.c, root.h: Added root smob.
4089 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4090 functions: Implements dynamic roots mostly according to spec in
4091 SCM manual. Main difference is that the second argument is a
4092 throw handler rather than an error "thunk".
4094 * root.h: Added declaration of scm_init_root.
4096 * root.c: Added #include "genio.h", #include "smob.h", #include
4097 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4099 (scm_init_root): Added #include "root.x".
4101 * throw.c: Added #include "stackchk.h"
4102 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4103 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4104 can be used in scm_call_with_new_root; Added reenabling of stack
4105 checking when catching a throw.
4107 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4109 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4111 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4112 element is not found, as per R4RS.
4114 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4116 * list.c: Doc fixes throughout.
4118 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4120 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4121 declare the char * to be const. Avoids a warning in rgx.c.
4123 * ports.h: spelling fix.
4125 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4128 * load.c (scm_sys_try_load_path): throw an error if file not found
4129 (like it says it in NEWS).
4131 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4133 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4134 PROPS slot to '(), not #f; it's an empty alist.
4136 * throw.h, throw.c: Use SCM_P instead of #if hair.
4138 Remove special support for uncaught throws; see throw.c for
4140 * throw.c (uncaught_throw): New function.
4141 (scm_ithrow): Call uncaught_throw if we don't find a throw
4142 target; don't mess with scm_bad_throw_vcell.
4143 (scm_bad_throw_vcell): Variable deleted.
4144 (scm_init_throw): Don't initialize it.
4146 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4149 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4151 * numbers.c (scm_istr2int): If the number is short (as most
4152 numbers are), just call scm_small_istr2int to deal with it.
4153 (scm_small_istr2int): New function, created by un-#ifdefing the
4154 non-bignum version of scm_istr2int and renaming it.
4156 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4158 * load.c (scm_sys_try_load): don't check whether value returned
4159 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4160 Change the Scheme name from %try-load to primitive-load.
4162 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4163 Can avoid passing a message, allowing it to be derived in the
4164 error handler (e.g., if we want to throw to the key both from
4167 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4169 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4170 references now have a new appearance which is more compact and
4171 also gives a clue about what the target of the reference is.
4172 By setting parameters in the print state, more fancy printing can
4173 be achieved. This is used by the (not yet commited) backtrace
4176 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4178 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4181 * print.c: Added #include "struct.h". Removed function
4184 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4185 scm_iprin1. Removed prototype for scm_prlist.
4187 * arbiters.c (prinarb),
4188 async.c (print_async),
4189 debug.c (prindebugobj, prinmemoized),
4190 eval.c (prinprom, prinmacro),
4191 filesys.c (scm_fd_print, scm_dir_print),
4193 mallocs.c (prinmalloc),
4194 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4195 smob.h (scm_smobfuns),
4196 srcprop.c (prinsrcprops),
4198 unif.c, unif.h (scm_raprin1, rapr1),
4199 variable.c (prin_var): Changed argument `int writing' to
4200 `scm_print_state *pstate'.
4202 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4203 that it will be called before scm_init_print.
4205 * print.c (scm_prin1): Print states are now allocated when calling
4206 scm_prin1 and then passed around to all printing functions as an
4207 argument. A cache `print_state_pool' enables reuse of print
4209 (scm_make_print_state): New function.
4210 (scm_iprin1): Adaption to print states.
4211 (scm_iprlist): An initial "hare and tortoise" scan brings down
4212 time complexity to O (depth * N). (Better time complexity will be
4213 achieved when the printing code is completely rewritten.)
4215 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4217 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4218 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4219 it gets done whether or not the cache variable has a value.
4221 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4223 Distinguish #f and ().
4224 * __scm.h: #undef SICP.
4225 * pairs.h (SCM_EOL): Delete this definition, equating it with
4227 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4228 the value it used to have. Doc fixes, too.
4230 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4232 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4233 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4234 Lord's implementation of structs, allowing for tail arrays as
4235 described in the manual. Also fixed some bugs. (Both the interface
4236 and the implementation should be improved.)
4238 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4240 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4241 People who whish to see the source can do `(print-enable 'source)'.
4242 Removed #ifdef DEBUG_EXTENSIONS.
4244 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4246 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4247 integer (assuming for now accepting an integer is a good thing).
4249 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4250 %S will be used instead for write'ing arguments.
4252 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4253 asserts. fix a few other asserts.
4254 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4255 scm_uniform_vector_ref, scm_array_set_x,
4256 scm_dimensions_to_unform_array): change args in
4257 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4258 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4259 scm_substring_fill_x): likewise.
4260 gsubr.c (scm_gsubr_apply): likewise.
4261 eval.c (SCM_APPLY): likewise.
4263 * eval.c (4 places): replace scm_everr with lgh_error or
4266 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4267 scm_memory_error): new procedures.
4268 scm_everr: deleted. can use scm_wta, dropping first two args.
4269 scm_error: convert NULL subr to SCM_BOOL_F.
4271 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4274 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4277 * error.c, error.h: new error keys: scm_arg_type_key,
4278 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4280 scm_wta: reimplement using lgh_error instead of scm_everr.
4282 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4284 * gdbint.c: scm_lread now has one more argument.
4286 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4287 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4288 loading source from non-file ports, which, e. g., happens when
4289 using the Emacs interface).
4291 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4294 * read.c: Added code for recording of positions of source code
4295 expressions; New functions: recsexpr, scm_lreadrecparen;
4296 _scm_make_srcprops --> scm_make_srcprops
4297 (scm_flush_ws): Removed updating of positions counters. This work
4298 is already done by scm_gen_getc
4300 * read.h: Added prototype for scm_lreadrecparen
4302 * print.c: Added #include "alist.h"
4304 * eval.c: Added #include "hash.h"
4306 * eq.c: Added #include "ramap.h"
4308 * options.c: Documentation fixes.
4310 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
4311 (scm_init_srcprop): Adjusted size of initial source-whash. Name
4312 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
4313 --> scm_make_srcprops
4315 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
4316 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
4317 function calls in the definition of the whash access macros.
4319 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
4321 * init.c (scm_boot_guile): Add level of indirection to
4322 scm_boot_guile_1() to ensure that stack base pointer is properly
4323 initialized. There was no guarantee that variable i was the
4324 highest/lowest variable on stack (i.e. the call frame of
4325 scm_boot_guile was not completely protected from gc).
4327 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
4329 * ports.h (scm_port_table): put back file_name, it will be used to
4330 support debugging. Undo related changes in fports.c, ioext.c,
4333 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4335 * ports.h (scm_port_table): remove file_name member for now, it seems
4337 * fports.c (scm_open_file): don't set file_name in PTAB.
4338 (prinfport): don't use file_name in PTAB.
4339 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
4340 * ports.c (scm_add_to_port_table): don't intialize file_name.
4341 (scm_port_file_name): remove for now.
4342 * gc.c (scm_gc_mark): don't mark PTAB file_name.
4344 * fports.h (scm_mkfile): prototype deleted.
4345 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
4347 * debug.c, unif.c: use scm_out_of_range instead of
4348 wta for range errors (ASSERT still needs work).
4350 * error.c, error.h (scm_out_of_range): new procedure.
4352 * error.c, error.h (scm_out_of_range_key): new key.
4354 * posix.c (scm_sync): #else was missing.
4356 * error.c, error.h: append _key to names scm_num_overflow and
4359 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
4360 of consing an empty list.
4361 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
4362 of macros, saves code and string space.
4363 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
4364 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
4365 lower case. Rename scm_syserror_m to scm_syserror_msg.
4366 error.h: prototypes for new procedures.
4368 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
4370 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
4372 * error.c, error.h: setup scm_num_overflow key.
4374 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
4375 Remove definition of SCM_OVSCM_FLOW.
4377 * fports.c (scm_open_file): use SCM_SYSERROR_M.
4379 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
4380 explicit message and args.
4382 * error.c, error.h, __scm.h: change system_error_sym to
4385 * error.c (system_error_sym): remove leading %% from the Scheme name
4388 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
4390 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4392 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
4393 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
4394 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
4395 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
4396 renamed. (These were introduced by unsupervised name
4399 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4401 * print.c: Added code for detection of circular references during
4402 printing. (init_ref_stack, grow_ref_stack): New functions. Added
4403 a hook for printing of closures (accessible via print options).
4404 This leads to a split of calls to scm_iprin1 into two classes:
4405 elementary print operations (e. g. the code which prints a smob)
4406 still use scm_iprin1 while top level calls (like scm_display) use
4407 scm_prin1. scm_prin1 begins by clearing the data structure used
4408 to record reference information.
4410 * print.h: Added declarations of scm_prin1 and scm_prlist.
4412 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
4414 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
4416 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
4418 * error.c (err_head): scm_iprin1 --> scm_prin1
4420 * debug.c: Adjusted header comment.
4424 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4426 * strerror.c: Doc fix.
4428 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4430 * gdbint.c (gdb_read): Now possible to run during GC.
4431 (unmark_port, remark_port): New functions.
4433 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
4435 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
4436 of allocating a new string object. Also, increase size by
4437 the factor 2 instead of 1.5.
4439 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
4441 * __scm.h (SCM_P): Corrected to run under traditional C.
4443 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
4446 * async.c: Calls to scm_sysintern corrected.
4448 * async.h (scm_async_clock): Redundant declaration removed.
4450 * continuations.c (scm_dynthrow): Redundant declaration removed.
4452 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
4453 Definition typos corrected.
4455 * debug.h: Missing declarations of functions in debug.c added
4458 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
4459 Missing declarations to functions in eval.c added.
4461 * filesys.c: Possibly uninitialized variable rv.
4463 * gc.h (scm_object_addr, scm_unhash_name): Missing
4464 declarations of functions defined in gc.c added.
4466 * genio.c: Possible typos str_data -> wstr_data. ???
4468 * genio.c: Possibly unintended shadowing of local variable
4469 `int c' (gotos out of scope of inner `c'). ???
4471 * init.c: Uninitialized `SCM last' may be used.
4473 * ioext.h: (scm_sys_isatty_p): Typo.
4475 * list.h (scm_list_head): Missing prototype for function in
4478 * numbers.c (scm_two_doubles): Changed from extern to static
4479 (is used only within numbers.c).
4481 * numbers.h: Repeated declarations removed.
4483 * ports.h (scm_close_all_ports_except): Declaration for the
4484 function defined in ports.c added.
4486 * posix.h: Missing declarations added.
4488 * procs.h (scm_make_subr_opt): Missing declaration added.
4490 * socket.h (scm_sys_gethost): Missing declaration added.
4492 * socket.h: Redundant declarations removed (they are in fdsocket.h).
4494 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
4495 Missing declarations added.
4497 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
4499 * struct.c: Uninitialized variable `SCM answer' may be used.
4501 * unif.c (l2ra): Declaration prototype.
4503 * unif.c (scm_array_equal_p): Dummy definition removed (it is
4504 defined in ramap.c).
4506 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
4507 Redundant declarations removed (they are in ramap.h).
4509 * variable.h (scm_make_udvariable,
4510 scm_make_undefined_variable): Declaration corrected to
4511 correspond variable.c.
4513 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
4514 Missing declarations added.
4516 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
4518 * Makefile.in (distclean): Don't forget to delete fd.h.
4520 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4522 * fd.h.in, tags.h: Trivial cleanups.
4524 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
4525 marksweep.h just declared functions from gc.c.
4526 * gc.h, libguile.h: Don't #include "marksweep.h".
4527 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4528 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
4529 dependencies updated.
4531 * libguile.h: Don't #include "files.h"; it's been deleted.
4533 * files.c (scm_sys_delete_file): Moved to filesys.c.
4534 File is now empty; deleted.
4536 * filesys.c: scm_sys_delete_file is now here. Remove
4537 #if's; they seem to rely on remnants of an old portability
4538 regimen. If the problems come up again, solve them properly,
4539 using autoconf. Specifically: Don't test M_SYSV, and #define
4540 remove to be unlink if it's #defined; don't use remove just
4541 because HAVE_STDC_HEADERS is #defined.
4542 * filesys.h: Add declarations for scm_sys_delete_file.
4543 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4544 files.o, files.h, files.c, and files.x.
4545 * init.c: Don't #include "files.h", and don't call scm_init_files.
4547 Use SCM_P instead of PROTO; the latter intrudes on the user's
4549 * params.h: Deleted; definition of SCM_P moved to...
4550 * __scm.h: ... here, where it replaces PROTO macro.
4551 * libguile.h, smob.h: Don't #include "params.h".
4552 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
4553 smob.h: Fix prototypes accordingly.
4554 * Makefile.in: Update dependencies.
4555 (inner_h_files): Remove params.h.
4557 * gc.c: #include "gc.h"; every module should include its header,
4558 to let the compiler cross-check the declarations against the
4561 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
4562 simpos.h: #include "libguile/__scm.h".
4564 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
4566 * init.c: Don't forget to #include smob.h and init.h.
4567 * Makefile.in: Dependencies updated.
4569 * smob.h: Use PROTO instead of #if __STDC__.
4571 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
4573 * __scm.h: Doc fixes.
4575 * __scm.h, libguile.h: Use "quotes" in the #includes, not
4576 <angles>; this allows `make depends' to work properly.
4578 * libguile.h: #include smob.h and pairs.h before the others; they
4579 define typedefs used by other headers.
4581 C files should #include only the header files they need, not
4582 libguile.h (which #includes all the header files); the pointless
4583 recompilation was wasting my time.
4584 * Makefile.in (all .o dependency lists): Regenerated.
4585 * libguile.h: Don't try to get a definition for size_t here...
4586 * __scm.h: Do it here.
4587 * _scm.h: Since this is the internal libguile header, put things
4588 here that all (or a majority) of the libguile files will want.
4589 Don't #include <libguile.h> here; that generates dependencies on
4590 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
4591 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
4592 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

4689 * weaks.c: Get "weaks.h".
4691 * stackchk.h: #include "libguile/debug.h",
4693 * print.h, read.h: #include "options.h", since everyone who uses
4694 either of these files will need that.
4696 * smob.h: #include "ports.h", "genio.h", and "print.h", since
4697 anyone who uses this file will need them to define the smob
4698 printing functions. Also, get markers.h, since people will need
4699 to #define the mark functions.
4701 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
4702 * ports.h: ... to here.
4704 * ports.h (scm_port_table_size): Explicitly give type as 'int';
4705 don't rely on archaic C default type rules.
4707 * fports.h: #include "libguile/ports.h", since you need that in
4708 order to parse this.
4710 * genio.h: #include "libguile/print.h", because you need that to
4711 parse this; don't bother #including "ports.h", since print.h gets
4714 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
4716 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
4717 this; it's now a reference to an element of *scm_root.
4719 * debug.h: Don't #include "options.h"; the compiler won't be able
4720 to find that once the headers are installed; instead, #include
4721 "libguile/options.h".
4722 * gc.h: Same, with marksweep.h.
4723 * mbstrings.h: Same, with symbols.h.
4724 * scmhob.h: Same, with _scm.h.
4725 * smob.h: Same, with params.h.
4727 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
4728 C files; there's no need for this, and it forces recompilations
4731 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
4733 * error.c (scm_error): declare scm_error_callback.
4735 * error.h: prototype for scm_error_callback.
4737 * __scm.h: define lgh_error.
4738 (SCM_SYSERROR): redefine using lgh_error.
4740 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
4742 * error.c (scm_error): new procedure.
4744 * error.h: prototype for scm_error.
4746 * Makefile.in (install): install scmconfig.h from the current
4747 directory, not $(srcdir).
4749 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
4751 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,

4762 dependencies are within libguile properly.
4764 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
4766 * Makefile.in (.c.x): Simplify; there's no need to run this rule
4767 when scmconfig.h doesn't exist.
4769 * load.c (scm_sys_try_load): Correct spelling.
4771 * feature.c (scm_loc_features): Make this static.
4773 * Makefile.in (libpath.h): Omit trailing slash from path. We
4774 shouldn't require it of users, so why put it here?
4776 Move code to initialize and search %load-path from ice-9 to C
4777 code, so we can use the load-path to find the ice-9 boot code;
4778 this makes it easier to run Guile without installing it. See
4779 corresponding changes in guile/Makefile.in.
4780 * feature.c: Move stuff concerned with the load path to load.c.
4781 (scm_compiled_library_path): Deleted.
4782 Don't #include libpath.h here.
4783 * feature.h: Don't mention scm_compiled_library_path.
4784 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
4785 <sys/stat.h>, and <unistd.h> (if present).
4786 (R_OK): #define if the system hasn't deigned to.
4787 (scm_loc_load_path): New variable.
4788 (scm_init_load_path, scm_sys_search_load_path,
4789 scm_sys_try_load_path): New functions.
4790 (scm_init_load): Initialize scm_loc_load_path to point to the
4791 value cell of the Scheme %load-path variable.
4792 * load.h: Add declarations for scm_sys_search_load_path,
4793 scm_sys_try_load_path.
4794 * init.c: Call scm_init_load_path.
4795 * Makefile.in (feature.o, load.o): Dependencies updated.
4797 * load.c, load.h: Rewrite using PROTO macro.
4799 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4801 * gc.c (scm_cellp): New function: C predicate to determine if an
4802 SCM value can be regarded as a pointer to a cell on the heap.
4804 * gc.h: Added declaration of scm_cellp.
4806 * gdb_interface.h: New file: The GDB interface header from the GDB
4809 * gdbint.c: New file: GDB interface.
4811 * gdbint.h: New file: GDB interface.
4813 * libguile.h: Added #include <libguile/gdbint.h>.
4815 * init.c (scm_boot_guile): Added scm_init_gdbint.
4817 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
4818 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
4819 found if object files and source are kept separate).
4821 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
4823 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
4825 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
4827 * configure.in: Don't substitute the values of TCL_SRC_DIR and
4828 TK_SRC_DIR; they're not relevant any more.
4830 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
4831 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
4833 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
4835 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
4836 search path, so we can find the <libguile/MUMBLE.h> headers.
4838 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
4840 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
4841 implicit in the .c.o rule.
4842 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
4845 Put the library path in a header file, instead of passing it on
4846 the command line in every compilation.
4847 * Makefile.in (libpath.h): New target.
4848 (feature.o): Depend on libpath.h.
4849 (clean): Delete libpath.h.
4850 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
4851 * feature.c: ... #include "libpath.h" here.
4852 * .cvsignore: Ignore libpath.h.
4854 Don't install the unwashed masses of Guile header files in the
4855 main #include path; put most of them in a subdirectory called
4856 'libguile'. This avoids naming conflicts between Guile header
4857 files and system header files (of which there were a few).
4858 * Makefile.in (pkgincludedir): Deleted.
4859 (innerincludedir): New variable; this and $(includedir) are enough.
4860 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
4861 (installed_h_files): Divide this up. Now this variable lists
4862 those header files which should go into $(includedir) (i.e. appear
4863 directly in the #include path), and ...
4864 (inner_h_files): ... this new variable says which files appear in
4865 a subdirectory, and are referred to as <libguile/mumble.h>.
4866 (h_files): List them both.
4867 (install): Create innerincludedir, not pkgincludedir. Put
4868 the installed_h_files and inner_h_files in their proper places.
4869 (uninstall): Corresponding changes.
4870 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
4871 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
4872 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
4873 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
4874 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
4875 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
4876 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
4877 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
4878 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
4879 vports.h, weaks.h: Find __scm.h in its new location.
4880 * __scm.h: Find scmconfig.h and tags.h in their new locations
4881 (they're both "inner" files).
4883 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
4885 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
4887 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4889 * posix.c: Doc fixes.
4891 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
4893 * socket.c: Don't include a prototype for inet_aton; just use a
4894 K&R style declaration, to avoid warnings but minimize the chance
4895 of conflicts with the system.
4897 On NextStep, <utime.h> doesn't define struct utime, unless we
4898 #define _POSIX_SOURCE before #including it.
4899 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
4900 * acconfig.h: New comment text for above CPP symbol.
4901 * configure.in: Call it.
4902 * posix.c: #define _POSIX_SOURCE if it seems necessary.
4904 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
4906 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
4907 testing for __EMX__.
4909 * posix.c: #include <libc.h>, if it exists.
4911 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
4912 don't even know if the latter exists.
4914 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
4915 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
4916 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
4918 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
4920 (scm_init_posix): Use them when initializing the Scheme constants
4923 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4925 * Makefile.in (libdir, includedir, bindir): Use the
4926 autoconf-supplied values, instead of deriving them ourselves.
4927 (pkgincludedir, datadir, pkgdatadir): New variables.
4928 (install, uninstall): Put the header files in a special
4929 subdirectory, not in the main search path.
4931 * Makefile.in (ALL_CFLAGS): Provide the proper value for
4932 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
4934 * Makefile.in (IMPLPATH): Deleted; never used.
4936 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
4937 on the Tcl/Tk source any more.
4938 (INCLUDE_CFLAGS): Remove references to the above.
4940 * Makefile.in (version.o): Corrected dependencies.
4942 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
4944 * libguile.h: #include "version.h"
4946 * init.c (scm_boot_guile): Call scm_init_version.
4947 * gscm.c (gscm_run_scm): Call scm_init_version.
4949 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
4950 GUILE_VERSION): AC_DEFINE these.
4951 (acconfig.h): #undef the above symbols.
4953 * Makefile.in (libobjs): Add version.o.
4954 (installed_h_files): Add version.h.
4955 (c_files): Add version.c.
4956 (gen_c_files): Add version.x.
4957 (version.o): New rule.
4958 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
4959 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
4960 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
4961 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
4962 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
4963 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
4964 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
4965 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
4966 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
4967 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
4968 weaks.o): Add version.h to dependency lists.
4969 (markers.o): Remove duplicate rule.
4971 * version.h: New file.
4973 * version.c: New file.
4975 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4977 * symbols.c (scm_strhash): scm_downcase is now a function, not an
4978 array; use it appropriately. Since GCC is quite happy to
4979 subscript functions, it never warned us about this; we should use
4980 -Wpointer-arith in the future. I guess we never tested
4983 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
4985 * socket.c: Doc and copyright fixes.
4987 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4989 * debug.c: Fixed and improved gdb support.
4991 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4993 * socket.c: Added declaration of inet_aton to avoid compiler
4994 warning. (Hope this solution is correct.)
4996 * stime.c: Added declaration of ftime. (This is missing in
4999 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5001 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5003 * Makefile.in (c_files): add strerror.c.
5005 * strerror.c: new file from Emacs' sysdep.c.
5006 maybe configure should also check for sys_errlist.
5008 * configure.in (AC_REPLACE_FUNCS): add strerror.
5010 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5012 * debug.c (scm_init_debug): Added initialization for
5013 scm_evaluator_traps.
5015 * debug.h, debug.c: Various name changes.
5016 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5017 "debug-options-interface". See commentary in options.c.
5019 * options.h, options.c: Options now have documentation strings.
5020 Also added a long explanatory commentary.
5022 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5025 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5026 last_debug_info_frame is now updated in all cases.
5028 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5031 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5033 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5034 Added option STACK_CHECKING.
5036 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5038 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5040 * __scm.h: Removed symbols for debugging support.
5042 * acconfig.h: Added symbols for debugging support.
5044 * configure.in: Added user option for debugging support.
5045 --enable-debug will include the debugging code into libguile.a.
5047 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5048 scm_relocate_chunk_to_heap.
5050 * debug.c: New file: low-level debugging support. It also
5051 includes support for debugging with gdb. (The extensions to gdb
5052 are written by Per Bothner at Cygnus.)
5054 * debug.h: New file: low-level debugging support.
5056 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5057 argument pairs. Extensive modifications to the debugging
5058 evaluator. Added "SECTION:" commentaries to clarify what happens
5059 when, during double compilation. Renamed EVALIMP --> EVALIM.
5060 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5061 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5062 the beginning of the file. New procedure: scm_unmemocopy.
5063 Added some global state variables needed by the debugging
5064 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5065 check_entry, check_apply, check_exit, debug_options and
5066 evaluator_traps. New acro: undefine.
5068 * eval.h: Renamed EVAL --> XEVAL.
5070 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5071 --> scm_make_weak_key_hash_table.
5073 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5074 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5076 * libguile.h: Conditionally include debug.h
5078 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5079 scm_object_properties shouldn't return handle. `handle' now gets
5080 initialized in scm_set_object_properties_x. scm_object_properties
5081 doesn't any longer create an entry in scm_object_whash.
5083 * options.c: New file: handling of run time options.
5085 * options.h: New file: handling of run time options.
5087 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5089 * print.c: New procedure: scm_print_options
5091 * print.h: Defines for print options.
5093 * read.c: New procedure: scm_read_options
5095 * read.h: Defines for reader options.
5097 * root.h: Added scm_source_whash among scm_sys_protects.
5099 * srcprop.c: New file: source properties.
5101 * srcprop.h: New file: source properties.
5103 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5104 (Bug found by A. Green.)
5106 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5108 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5110 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5112 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5114 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5115 and should be called by the final client.
5117 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5119 * gc.h: Use the PROTO macro when declaring functions.
5120 * gc.c: Use the PROTO macro when declaring static functions.
5121 Remove the CPP hair around function definitions.
5123 * gc.c (scm_init_storage): Initialize scm_asyncs.
5125 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5126 preprocessor symbol; "__scm.h" is where it might get #defined.
5127 * __scm.h: Similar: #include <scmconfig.h> before testing
5130 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5132 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5134 * init.c (scm_boot_guile): Add init_func argument; call
5135 (*init_func) instead of calling scm_appinit; it's ucky to
5136 hard-code names for the user's procedures.
5137 * init.h (scm_boot_guile): Adjust declaration.
5139 * __scm.h (PROTO): New macro, for declaring functions with
5142 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5143 eliminate all the __STDC__ conditionals.
5144 (scm_boot_guile): Add declaration.
5145 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5146 Remove __STDC__ conditionals around function definitions; the
5147 declarations in init.h will provide the same information, more
5150 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5151 complain about it in the error message; the error message is
5152 adequate without that note, and there's nothing the user can do
5155 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5157 * Makefile.in (ancillary): Drop def.sed.
5159 * posix.c (scm_init_posix): Use numeric values, rather than
5160 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5161 F_OK. The symbols aren't available on some systems, and I'm
5162 pretty sure their values are fixed by common widespread practice.
5163 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5165 More functions unavailable on some systems.
5166 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5167 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5169 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5170 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5171 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5172 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5173 stub that signals an error as the #else.
5175 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
5177 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
5179 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
5181 * unif.c: include ramap.h.
5183 * read.c (endif): case_insensative_p renamed case_insensitive_p.
5185 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
5187 * ports.c: include sys/ioctl.h.
5189 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
5191 * configure.in: check for sys/ioctl.h.
5193 * ports.c: include <malloc.h> not "malloc.h".
5195 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5197 * fports.c: remove ttyname and tmpnam declarations.
5199 * posix.c: fewer ttyname declarations.
5201 * fports.c: include <string.h> not "string.h".
5203 * init.c, ioext.c: include string.h and unistd.h.
5205 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5207 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
5208 genio.c, simpos.c, vports.c: include string.h.
5210 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
5212 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
5214 (scm_addr_buffer_size): change type from scm_sizet to int.
5215 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
5216 from scm_sizet to int.
5218 * error.c: include unistd.h.
5220 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
5223 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
5225 * __scm.hd, def.sed: deleted.
5227 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
5229 Changes for NeXT, suggested by Robert Brown.
5230 * configure.in: Call AC_TYPE_MODE_T.
5231 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
5232 NeXT. Put header file list in alphabetical order.
5233 * configure, scmconfig.h.in: Regenerated.
5234 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
5236 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
5239 * acconfig.h: New file, providing documentation for the CPP
5240 symbols defined in configure.in
5241 * acconfig-1.5.h: Removed; superceded by the above.
5243 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
5245 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
5247 * fports.c (scm_open_file): don't return #f, throw error.
5249 * ioext.c (fileno): renamed from %fileno.
5250 (soft-fileno): deleted.
5252 * ports.c (scm_port_revealed): don't need to check for -1 from
5254 (scm_set_port_revealed_x): return unspecified, not #f.
5256 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
5258 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
5260 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
5262 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
5264 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5266 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5267 This is necessary on Ultrix, and doesn't hurt portability.
5269 * Makefile.in (dist-dir): New target, implementing a new dist system.
5270 (installed_h_files): Put in alphabetical order.
5271 Remove duplicate entries for markers.h and unif.h.
5272 (c_files): Remove duplicate entries for markers.c.
5273 (ancillary): Renamed from anillery; all uses changed. Remove
5274 PLUGIN; it's a directory, and needs special treatment in dist-dir.
5275 Remove all the ../doc/* files; doc/Makefile.in handles that.
5277 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5279 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5280 every if must have an else, or else the whole command has a
5281 non-zero exit code whenever the if's condition is false.
5283 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>

5540 initialization to fix a race condition.
5542 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
