1 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
4 scm_copy_tree on code in order not to let memoized code to leak
5 out. Thus, scm_copy_tree needs to copy vectors as well since
6 quasiquote can introduce evaluated code also inside vector
9 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
11 * eval.c (scm_copy_tree): Removed ability to copy vectors.
13 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
14 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
17 * unif.c: Say that ivect and uvect are of type signed and unsigned
18 long instead of int in commentary so that it correctly describes
21 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
23 * stime.c: Removed declaration of strptime. (It should be
24 declared by the system headers. If it turns out that some systems
25 don't, we'll handle that then.) (Thanks to Greg Troxel.)
27 * stime.h: Renamed TIMEH --> STIMEH
29 * backtrace.c (scm_display_error, scm_display_backtrace): In order
30 to increase portability, don't use structure assignment.
31 (Thanks to Nicolas Neuss.)
33 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
35 (finalize_fd_sets): Added empty statement after last case label.
36 (Thanks to Nicolas Neuss.)
38 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
41 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
43 * init.c, readline.c: OK, I won't have these readline.x bug
44 reports anymore. We've had them since April. The current reason
45 is a completely unintelligible failure of totoro.red-bean.com to
46 do the test for rl_getc_function in libreadline correctly. This
47 kludge overrides the test if we're on totoro so that the snapshot
48 generation process can work.
50 * readline.c: Define a strdup replacement if not existent on system.
52 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
54 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
55 This change makes scm_make_vector R5RS compatible. We cannot keep
56 the third argument since people want to be able to deduce the form
57 of the C function call only by looking at R5RS. (At the same time
58 we have removed some unnecessary complexity!)
60 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
61 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
62 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
63 argument in call to scm_make_vector.
65 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
67 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
68 This macro is useful in applications.
70 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
72 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
73 (scm_parse_path, scm_search_path): New Scheme level procedures.
75 * load.h (scm_internal_parse_path, scm_parse_path,
76 scm_search_path): Declared.
78 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
80 * filesys.c (dirname, basename): New procedures.
82 * init.c (scm_boot_guile_1): Removed condition around
85 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
86 new data type (guards) for representation of C level guards and
87 data on the wind chain.
88 (scm_internal_dynamic_wind): New function.
90 * dynwind.h: Declare scm_internal_dynamic_wind.
92 * root.h (scm_root_state): Added scm_cur_loadp.
94 * root.c (mark_root): Added comment about cur_loadp.
96 * load.c: #include "dynwind.h";
97 (scm_primitive_load): Use scm_inner_dynamic_wind to update
100 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
102 * ports.c (current-load-port): New procedure.
104 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
106 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
107 not a tty, return #f.
109 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
110 to Julian Satchell and Roland Kaufmann.)
112 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
113 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
115 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
117 * debug.h, debug.c (scm_start_stack): New function. Implements
118 the guts of old scm_m_start_stack.
120 * debug.c (scm_m_start_stack): Use scm_start_stack.
122 * init.c (scm_start_stack, scm_restart_stack): Renamed to
123 start_stack and restart_stack. (These have static scope.)
125 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
127 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
128 readline functions to come in release 2.3. (Thanks to Chet
130 (handle_errors): Use the above functions.
132 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
134 * readline.c: Improvements for readline support: Handle errors
135 better; Implement before-read-hook.
137 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
139 * init.c (scm_boot_guile_1), readline.c: Test for
140 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
141 assure that we have version >= 2.1.)
143 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
145 * readline.c (scm_add_history): Bugfix: Do strdup before giving
146 away the string to add_history.
147 (completion_function): Do completion for readline. (Thanks to
149 (scm_filename_completion_function): New procedure: Filename
151 (current_input_getc): New function. Use this one instead of
152 standard getc from readline.
154 * throw.c, throw.h (scm_handle_by_throw): New function: This
155 handler throws errors to next handler on the dynwind chain.
157 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
159 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
162 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
164 * procprop.c (scm_i_procedure_arity): New function. Returns arity
166 (scm_procedure_properties): Modified to return arity together with
168 (scm_procedure_property): Added the read-only property `arity'.
169 (scm_set_procedure_property_x): It is an error to set the `arity'
172 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
173 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
175 * procprop.h (scm_sym_arity): New symbol.
177 * objects.c (scm_set_object_procedure_x): New procedure: Use this
178 to set the dispatch procedure of an operator or entity object.
180 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
181 Made procedure slots read-only.
183 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
184 scm_tcs_cons_gloc case in zero args switch; Fixed args
185 construction for operators in scm_tcs_cons_gloc case in two args
188 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
190 * fluids.c: Removed use of assert.h (in order to avoid
193 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
195 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
197 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
198 change makes the evaluator safer at the cost of evaluation speed.
199 It handles the case when the user has added a non-immediate
200 improper end of the application form, e.g., `(+ 0 . x)'.
201 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
202 minimize the extra cost as much as possible. The new code is
203 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
204 problem with structs planted directly in the code (e.g. by a
205 macro). This no longer causes segmentation fault. (Thanks to
208 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
209 arg `proc' in order to be able to throw errors; New argument
212 * Removed extra #include "debug.h"
214 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
216 * scmsigs.c: Declare usleep as returning void on some systems.
217 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
220 * coop.c (usleep): Return void on some systems.
222 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
224 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
226 * coop.c: Changed return type of usleep to int.
228 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
229 isn't found in the OS.
231 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
232 isn't enabled. (Thought that I had made this change ages ago...)
234 * iselect.c: Declare bzero if not defined by OS.
236 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
238 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
239 condition. (Thanks to John Tobey.)
241 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
242 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
245 * __scm.h: Start the long-term project of moving to POSIX threads.
246 Phase 1: Classification of all critical sections.
247 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
248 for A sections. (See comments in __scm.h for details.)
250 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
251 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
253 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
255 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
256 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
257 (libpath.h, versiondat.h): Replaced dependency on Makefile with
258 dependencies on $(srcdir)/Makefile.in
259 $(top_builddir)/config.status in order to avoid circularity.
261 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
262 from argc if argc was 0 initially.
264 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
265 in generation of libpath.h.
267 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
269 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
270 libguile from 2 to 3.
272 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
274 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
276 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
278 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
279 scm_set_port_column_x, scm_port_filename,
280 scm_set_port_filename_x): Removed optional arguments. Added
281 proper argument checking.
283 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
284 stack size in machine words.
286 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
287 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
288 to Ole Myren Röhne.)
290 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
292 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
293 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
295 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
298 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
299 procedure apply: Copy argument lists before pushing them unto the
300 environment so that the environment won't get mutated due to
301 manipulation of procedure arguments. This should perhaps be
302 regarded as a temporary solution until someone finds a more
303 efficient one. (Thanks to Maciej Stachowiak.)
305 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
307 * script.c (scm_compile_shell_switches): Use "guile" as default
308 zero arg if argc is NULL.
310 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
312 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
313 is zero. (Thanks to Dirk Herrmann.)
315 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
317 * ports.c (scm_add_to_port_table): First line is now line 0
318 (was 1). (Interface changed according to suggestion by Per
321 * backtrace.c (display_header): Add 1 to line and column numbers
322 when presenting them to the user.
324 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
325 from debug.c --> eval.c
327 * eval.h, eval.c (scm_eval_options_interface): New options
329 (SCM_EVAL_STACK): New option: Size of newly created stacks,
330 i.e. stacks for new threads.
332 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
334 * eval.c (unsafe_setjmp): Removed with #if 0.
336 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
339 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
340 to avoid compiler warnings.
342 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
344 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
346 * throw.c (handler_message): Print message on current error port
347 instead of default error port. (Thanks to Maciej Stachowiak.)
349 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
351 * ports.c (scm_add_to_port_table): allocate in units of
352 struct scm_port_table *, not struct scm_port_table.
353 * posix.c (scm_close_pipe): remove the port from the port table
355 Thanks to Rob Engle for both fixes.
357 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
359 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
360 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
362 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
364 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
366 * backtrace.c (display_error_body, display_backtrace_body),
367 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
368 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
369 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
370 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
373 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
374 don't receive the jmpbuf arg anylonger.
375 (scm_catch): Don't accept a #f tag.
376 (scm_throw): Check that key is a symbol.
377 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
379 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
381 * async.c (async_pending): Removed declaration.
383 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
385 * dynwind.c (scm_wind_chain): New debug function.
387 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
388 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
389 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
390 extra layer of functions around the body and handler of a thread.
391 This extra layer makes sure that the handler is called in the
392 dynamic context of the surround (= empty dynwind list), but under
393 the *dynamic root* of the body. We can not use the dynamic root
394 of the surround since that root belongs to another thread => stack
395 is not handled correctly. It may seem ugly to use this extra
396 layer, but the extra cost in terms of execution time is really
397 negligible compared to the total amount of time required to create
398 a thread, and it would reduce maintainability to duplicate the
399 crucial and complicated steps performed by cwdr.
401 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
402 (SCM_ALLOW_INTS): Added thread switching code before interrupts
403 get re-enabled. The important effect of this is that interrupts
404 are blocked during thread switching so that thread data structures
405 don't risk getting messed up by an unfortunate signal.
406 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
407 seems to do more aggressive optimization which actually move
408 instructions around in these macros in a fatal way. Therefore:
409 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
410 just superstitious...)
411 (SCM_TICK): Maybe do a context switch and take care of asyncs.
412 This macro should be used instead of SCM_ASYNC_TICK since the
413 latter doesn't do context switches any more.
415 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
416 instead of SCM_ASYNC_TICK.
418 * coop.c, iselect.c: Since thread switches are now performed with
419 interrupts masked, we can't use the old mechanism of delivering
420 signals immediately when they arrive. Signals must instead be
421 delivered when the asyncs run *after* the end of the critical
422 section in scm_internal_select. But this also means after context
423 switch so that the signal will be delivered to a different thread.
424 To avoid this, I have changed the protocol of
425 coop_wait_for_runnable_thread and friends so that they are allowed
426 to return the original thread. So, if a signal arrives during
427 scm_internal_select, we won't any longer be forced do a context
428 switch, but can remain in the same thread and deliver the signal
431 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
432 scm_asyncs_pending and made it global.
434 * iselect.c: Small fixes.
436 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
437 coop_condition_variable_init, coop_condition_variable_wait,
438 coop_condition_variable_signal): Changed return type from `void'
439 to `int'. This is to adhere closer to the pthreads interface.
440 This, in turn, is part of an attempt to provide C versions of the
441 mutex and condition variable primitives which can be part of a
442 frontend to COOP or pthreads.
444 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
445 coop_condition_variable_destroy): New functions.
447 * coop-threads.c (scm_wait_condition_variable): Use
448 coop_condition_variable_wait_mutex.
450 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
451 Definitions moved to coop-defs.h.
453 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
454 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
455 scm_cond_destroy): New C interface to mutecis and cond vars.
457 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
459 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
461 * iselect.c: Now several threads can wait on the same file
462 descriptor. The behaviour is compatible with OS select: All
463 threads waiting for the fd return with the same status.
465 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
467 * coop-threads.c, threads.h (scm_spawn_thread): New function.
468 Can spawn a thread from application C code.
470 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
472 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
473 gh_doubles2scm): New functions.
475 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
477 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
478 commented-out version of gh_eval_str()
480 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
482 * socket.c (scm_bind): free soka after use.
484 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
486 * stime.c (tzvar): new variable.
487 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
488 avoid memory leaks when allocating.
490 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
492 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
495 * gc.c, tags.h: Doc fixes.
497 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
499 * eval.c (macro-eval!): Removed. This function was a design bug.
500 It allowed memoized code to leak out to the scheme level. Most
501 things that you could do with `macro-eval!' can be done with
504 1997-12-20 Tim Pierce <twp@skepsis.com>
506 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
507 scm_fgets now depends on ftell(3) to know how many bytes were
510 1997-12-15 Tim Pierce <twp@skepsis.com>
512 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
513 dealing with strings.
515 1997-12-13 Tim Pierce <twp@skepsis.com>
517 Make %read-line more suitable for implementing read-line efficiently.
518 * ioext.c (scm_read_line): Strip the terminating newline from a
519 string, and return a cons of the string and its terminator.
521 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
522 of the string that is read is stored in this memory location.
523 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
524 * genio.c, genio.h (scm_do_read_line): Update caller.
525 * ports.h (scm_ptobfuns): Update typedef.
526 * fports.c (scm_fptob, scm_pipob): Update struct.
528 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
530 * filesys.c (set_element): Return file descriptor.
531 (fill_select_type): Return the highest file descriptor.
532 (scm_select): Tell select about the highest file descriptor. On
533 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
534 Therefore the extra overhead for calculating the maximum fd seems
535 to be more than compensated. Is this correct? In any case,
536 scm_internal_select will be much faster with this info.
537 (scm_select, fill_select_type, set_element): Don't accept any kind
538 of object in the file descriptor list or vector.
540 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
542 * iselect.c (finalize_fd_sets): Bugfix.
544 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
546 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
547 when using scm_internal_select (since we might switch to another
550 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
552 * simpos.c (scm_system): always define: use sysmissing if not
553 available. Check for HAVE_SYSTEM instead of _Windows (does
554 Windows lack system or does it have an unusable one?).
555 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
556 Let the argument be optional: if not supplied, call system(NULL).
558 * ports.c (scm_close_port): relax the type check from OPPORTP to
559 PORTP; closing a closed port is allowed.
561 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
563 * fports.c (scm_fgets): Return if the last char in a chunk is
564 newline. When fgets returns a string whose length is `size-1', it
565 is ambiguous whether a whole line was retrieved, so we must check
566 explicitly whether a line terminator is present.
568 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
570 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
571 before taking the CDR. (Thanks to Harald Meland.)
573 * filesys.c (scm_stat): Slightly optimized.
575 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
577 * ports.c (scm_close_port): Make sure the port is open before
580 * guile-snarf.in: Pass args through to gcc in a way that preserves

583 1997-12-02 Tim Pierce <twp@skepsis.com>
585 * stacks.c (scm_frame_procedure): Reverse the logic in the return
586 statement. (Thanks to Doug Evans for pointing this out.)
588 1997-12-01 Tim Pierce <twp@skepsis.com>
590 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
592 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
594 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
595 errno macro expansion of this field name. (errno is a C
596 preprocessor macro on some systems.)
598 1997-11-29 Tim Pierce <twp@skepsis.com>
600 * iselect.c: Doc fix.
602 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>

605 scm_the_last_stack_var.
607 * backtrace.h: Declare scm_the_last_stack_var.
609 * backtrace.c: Define scm_the_last_stack_var.

613 * root.h (scm_root_state): Removed the_last_stack_var.
615 * throw.c: Added #include "fluids.h"
616 (ss_handler): `the-last-stack' is now a fluid.
618 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
619 --> the_last_stack_fluid.
621 * backtrace.c: Added #include "fluids.h"
622 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
623 (scm_backtrace): `the-last-stack' is now a fluid.
625 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
626 after scm_init_fluids.
628 1997-11-28 Tim Pierce <twp@skepsis.com>
630 * iselect.c: #ifdef USE_THREADS around thread-related includes.
632 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
633 DLSYM_ADDS_USCORE to decide whether to add an underscore.
635 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
637 * iselect.c (coop_next_runnable_thread,
638 coop_wait_for_runnable_thread): Disable interrupts so that no
639 async is executed before a potential error_revive.
640 (scm_internal_select): Disable interrupts during the parts of the
641 code which manipulate the sleep queue and the file descriptors.
643 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
645 * Makefile.am: Added iselect.c and iselect.h.
647 * coop.c (coop_qinit): Initialize fields used by
649 (coop_qget, coop_qget, coop_tmp_queue): Made global.
650 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
651 replacement in iselect.c.
652 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
653 coop_join): If GUILE_ISELECT enabled, use
654 coop_wait_for_runnable_thread instead of
655 coop_next_runnable_thread.
656 (usleep, sleep): New replacements for system functions if
657 GUILE_ISELECT is enabled.
659 * coop-threads.h: Declare coop_wait_for_runnable_thread.
661 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
663 * filesys.c: Added #include "iselect.h". Moved FD-macros to
664 iselect.h. Implement Scheme level `select' using
665 scm_internal_select. (See NEWS.)
667 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
669 * init.c: Call scm_init_iselect.
671 * iselect.h, iselect.c: New files. Implements
672 scm_internal_select. (See NEWS.)
674 1997-11-27 Tim Pierce <twp@skepsis.com>
676 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
677 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
678 and scm_must_free, since ultimately the string returned will be copied
679 by scm_makfrom0str anyway. Also, read any characters that may have
680 been pushed onto the port with scm_ungetc.
681 * ports.c (scm_generic_fgets): Same as for scm_fgets.
682 * ioext.c (scm_read_line): Free string after Guilifying it.
683 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
685 1997-11-26 Anthony Green <green@hoser.cygnus.com>
687 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
689 * gh.h: Safely wrap prototypes for c++ usage.

694 gh_repl (argc, argv).
696 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
698 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
699 and to invoke scm_shell().
700 (gh_launch_pad): took out the loading of boot-9.scm from here,
701 since it is probably best to let the user control that. In fact,
702 gh_repl() now invokes scm_shell() which does that.
704 1997-11-23 Mark Galassi <rosalia@cygnus.com>
706 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
709 1997-11-22 Tim Pierce <twp@twp.tezcat.com>

728 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
729 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
731 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
733 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
734 configure.in was changed).
736 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
738 * Makefile.am (modinclude_HEADERS): Include readline.h here.

741 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
743 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
744 OPORT is an `open' port, not an output port.

752 scm_set_port_filename_x, scm_port_mode,
753 scm_close_all_ports_except, scm_set_current_output_port,
754 scm_set_current_error_port): Likewise
755 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
756 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
758 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
759 * backtrace.c (display_backtrace_body): Likewise
760 * fports (scm_setvbuf): Likewise
761 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,

766 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
768 Minor problems with substring-related tag changes.
769 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
770 exactly what we want to leave in to detect substrings.
771 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
772 * tags.h: Fix diagrams and comments describing the S tag bit;
773 remove vestigial remarks about the D tag bit.
774 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
775 * strings.c: Formatting tweaks.
777 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
778 variable first; then SCHEME_LOAD_PATH, with a warning message.
779 (scm_parse_path): New function.
780 * script.c: Doc fixes.
782 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>

796 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
798 * gh_data.c (gh_vector_set_x): changed name to make it consistent
799 with the ! -> _x mapping when going from Scheme to C.
801 1997-10-19 Mark Galassi <rosalia@cygnus.com>
811 (gh_assoc): added these gh_ functions implemented as macros.
813 * gh_predicates.c (gh_null_p):
814 (gh_string_equal_p): added these two missing predicates.
816 * gh_list.c (gh_append):
821 (gh_set_cdr_x): added these routines as I go through and try to
822 complete the picture R4RS functions that should be mirrored in the

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

893 * gh_test_c.c (c_vector_test): some improvements on the vector
896 * gh.h (gh_vector): this used to exist but do the wrong thing.
897 Now it (almost) does the right thing, though it takes a list
898 instead of the individual arguments. I need to see how it could
900 (gh_list_to_vector): added this function as a macro. Corresponds
901 to Scheme's (list->vector ...).
902 (gh_vector_to_list): added this function as a macro. Corresponds
903 to Scheme's (vector->list ...).
905 * gh_data.c (gh_vector_ref): renamed from gh_vref to
906 gh_vector_ref, so that it resembles the Scheme routines more.

908 resembles the Scheme routines more.
909 (gh_make_vector): this used to be (stupidly) called gh_vector().
910 This is the right name, since it does the same thing as the Scheme
911 (make-vector ...) procedure.

930 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
932 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
933 macros should by convention not test for NIMPness.)
934 (SCM_COERCE_OPORT): Adjust indentation.
936 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
937 SCM_NIMP test before SCM_PRINT_STATE_P.

948 will be indicated as well.
949 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
950 Removed struct_printer_var; Removed struct-vtable-offset;
951 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
952 vtable-offset-user): New constants.
954 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
955 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
956 If this slot contains a procedure, use that to print structures of
957 the type represented by this vtable.
959 * print.c (scm_iprin1): Don't print arguments of macro
960 transformers. (They are always: exp env.); Bugfix: Unmemoize
961 transformer source with correct environment.
963 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
965 Streamlining of call-with-dynamic-root:
967 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
968 there is now only one catch.
969 (cwdr_outer_body): Removed.
970 (cwdr_handler): New function.
971 (scm_internal_cwdr): New function to perform the function of cwdr
972 but take args that are more useful to C code. Also, the handler
973 is now invoked *outside* of the new dynamic root, like the docs
974 say. We no longer have to catch absolutely all errors, the caller
975 is responsible for using a handler that does not throw, if he
977 (cwdr): Reimplemented in terms of scm_internal_cwdr.
978 * root.h (scm_internal_cwdr): New prototype.
980 Even more but risky streamlining:
982 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
983 allocation of the jumpbuf of a root continuation. The changes
984 below are controlled by it. They are now deactivated.
985 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
986 the JMPBUF of the scm_rootcont to NULL before returning.
988 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
989 when they are non-NULL.
990 (scm_gc_mark): Likewise, mark only when non-NULL.
992 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
993 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
995 * gc.c (scm_done_malloc): New function.
996 gc.h (scm_done_malloc): New prototype.
998 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.

1007 (scm_free_print_state): Set `revealed' field to false.
1008 (scm_iprin1): Call user supplied closure printer with

1012 Accept a port/print-state pair in addition to just a port.
1013 (scm_prin1): Don't return the print_state to the pool when it has
1015 (scm_printer_apply): Set `revealed' field of print_state to true.
1016 (scm_init_print): Set scm_print_state_vtable.

1026 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1028 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1029 was looping endlessly.
1031 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1033 * strports.c (scm_eval_string): Don't close the port.
1035 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1036 former returns a nice normal integer. (Thanks to Daniel
1039 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1041 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1042 makefile variable as a build parameter called LIBS. The
1043 build-guile program will use this, for the time being.
1044 * Makefile.in: Regenerated.
1046 Thanks to Shiro Kawai:
1047 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1048 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1051 * Makefile.in: Regenerated with automake 1.2a.
1053 * script.c (scm_compile_shell_switches): If we hit the -c or --
1054 arguments, don't set the car of (command-line) to scm_usage_name,
1055 the prettified name of the guile executable; give it the full
1056 path, the way shells usually handle $0.
1058 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1060 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1061 Scheme-level name `array-map' and renamed `serial-array-map' to
1062 `serial-array-map!'.
1064 * backtrace.c: Introduced exception handlers which now enclose
1065 `display-error' and `display-backtrace' so that error reporting
1066 won't get into infinite loops if an error occurs during displaying
1067 of the error. This can very easily happen with user supplied
1068 print call-back routines.
1070 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1072 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1073 the names `serial-array-map' and `array-map' should be removed.)
1075 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1077 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1078 Added #include "objects.h"
1080 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1081 Add #include "feature.h".
1083 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1084 (modinclude_HEADERS): Added objects.h.
1086 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1087 This test is needed at many places in the code and should be
1088 abstracted. (Motivated by the need of this test in libguiletk.)
1090 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1091 (scm_eval_string), load.c (scm_primitive_load,
1092 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1093 Use SCM_EOF_OBJECT_P.
1095 * eval.c (scm_init_eval): Add feature `delay'.
1097 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1099 * scmhob.h: Removed.
1101 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1103 * list.h (SCM_LISTn): New macros. Make list creation in C code
1104 prettier. The idea comes from STk.
1106 * sequences.h, sequences.c, append.h, append.c: Removed. These
1107 files implemented non-R4RS operations which would encourage
1108 non-portable programming style and less easy-to-read code.
1110 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1113 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1114 sequences.h, #include append.h.
1116 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1119 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1121 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1123 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1125 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1127 * eval.c: Added #include "objects.h"
1129 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1132 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1133 adjacent smob numbers.
1135 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1137 * procprop.h: Added declaration of scm_i_inner_name.
1139 * gsubr.c: New global symbol scm_i_inner_name.
1141 * debug.c (scm_procedure_name): Try procedure property
1142 `inner-name' if `name' fails.
1144 * print.c (scm_iprin1): Use scm_macro_name.
1146 * eval.c (scm_m_define): Give names to macros as well; Only the
1147 first top-level definition gives a procedure/macro a name.
1148 Otherwise confusing names can turn up in backtraces.
1149 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1150 `name'; Give names to macros as well.
1152 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1153 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1156 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1158 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
1160 (prinmacro): Removed. The code has been moved/merged into print.c
1161 in order to decrease code redundancy. We want macros to print in
1162 a way equivalent to procedures, and it would be silly to duplicate
1163 the required code. (We don't want to maintain two places.)
1164 (macrosmob): Print field is now a NULL pointer.
1166 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1167 scm_macro_transformer): New prototypes.
1168 (scm_tc16_macro): Declared.
1170 * * print.c (scm_iprin1): Added code for printing of macros. Macros
1171 are now printed in a way equivalent to procedures.
1173 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1175 * procs.h (scm_closure_p): Added declaration.
1177 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1179 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
1180 Shouldn't pass "heap" as the subr name.
1182 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1184 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
1185 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
1186 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1187 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1188 SCM_BOOL_T. Any non-false value is true.
1190 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1192 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1193 scm_gensym): Added prototypes.
1195 * symbols.c (scm_gensym): New function. This will speed up
1196 certain types of applications (such as macro systems) which
1197 generate lots of symbols.
1199 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1201 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
1203 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
1205 * unif.c (scm_shap2ra): tighten the checking of the array dimension
1206 specifier, since (2) or (2 . 3) would cause SEGV.
1207 (scm_transpose_array): more argument checking fixes.
1209 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1211 * Makefile.in: Regenerated.
1213 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1215 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
1217 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1219 * error.c, error.h (scm_error_callback): Removed (see NEWS).
1221 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
1223 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
1224 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
1227 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
1228 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1229 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
1230 scm_array_p, scm_array_rank, scm_array_dimensions,
1231 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
1232 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
1233 scm_array_prototype): Added case scm_tc7_wvect.
1235 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
1237 * errno.h: prototype for scm_strerror.
1238 * error.c (scm_strerror): new procedure.
1240 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1242 * list.c (scm_list_append_x): Allow non-pair as last argument.
1243 This is consistent with the R4RS append and is probably the
1244 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1246 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1248 * stime.h: prototype for scm_times.
1249 * stime.c (scm_times): new procedure.
1250 * ioext.c (scm_fseek): if the first argument is a file descriptor
1252 (scm_ftell): if the first argument is a file descriptor call lseek
1254 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
1255 * filesys.c (scm_chmod): if the first argument is a file descriptor,
1257 (scm_chown): if the first argument is a port or file descriptor,
1259 (scm_truncate_file): new procedure.
1260 Add DEFER/ALLOW INTS to a few other procedures.
1261 (scm_fsync): new procedure.
1262 (scm_open_fdes): new procedure.
1263 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
1265 (scm_fcntl): the first argument can now be a file descriptor. The
1266 third argument is now optional.
1268 * posix.c (scm_execl, scm_execlp): make the filename argument
1269 compulsory, since omitting it causes SEGV.
1270 (scm_sync): return unspecified instead of #f.
1271 (scm_execle): new procedure.
1272 (environ_list_to_c): new procedure.
1273 (scm_environ): use environ_list_to_c. disable interrupts.
1274 (scm_convert_exec_args): take pos and subr arguments and
1275 improve error checking.
1277 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1279 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1280 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1281 argument to SCM_ASSERT. Furthermore, the name of the function
1282 should be passed as first argument when signalling
1283 SCM_WNA. (Thanks to Thomas Morgan)
1285 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1286 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1287 dispatches on the number of actual args has a default case
1288 reporting an internal error. This is a vestige from a version
1289 that mallocated a SCM vector to hold the arguments. In the
1290 current version this check is too late: if it ever happens we will
1291 have already overstepped the bounds of the array.
1293 Also, the patch [...] adds a check for too many actual arguments."
1295 mdj: Removed check for "internal programming error".
1297 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1299 * gh_io.c (gh_write): New function.
1301 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
1302 throw.c (scm_internal_stack_catch): New sibling to the other catch
1303 functions. Code moved from gh_eval.c.
1304 throw.h: Added header.
1305 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
1306 scm_internal_stack_catch.
1308 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1310 * ioext.h: fix up prototypes.
1311 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
1312 Scheme name is now dup->fdes.
1313 (scm_dup_to_fdes): make the second argument optional and
1314 fold in the functionality of scm_primitive_dup.
1315 (scm_primitive_dup): deleted.
1317 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1319 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
1320 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
1321 ultrix are defined. Use setvbuf instead of setbuf.
1322 (scm_setvbuf): new procedure.
1323 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
1324 (scm_setfileno): moved from ioext.c.
1325 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
1326 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
1328 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1330 * fluids.c (scm_fluid_p): New function.
1331 * fluids.h (scm_fluid_p): New prototype.

1335 * print.c (scm_iprin1): Enter printed structures into the print
1336 state as nested data while they are printed.
1337 (print_state_fluid, print_state_fluid_num): New variables.
1338 (scm_init_print): Initialize them.
1339 (scm_iprin): If print_state_fluid carries a print_state, use that
1340 instead of creating a new one.
1341 (scm_printer_apply, apply_stub, struct apply_data): New
1342 definitions to help with calling printer functions written in
1344 * print.h (scm_printer_apply): New prototype.
1346 * struct.c (scm_print_struct): Use scm_printer_apply to call the
1347 user defined struct printer.
1349 * dynwind.c (scm_dowinds): Handle fluids on the wind list.
1350 * fluids.h (scm_internal_with_fluids, scm_with_fluids,

1355 Fri Jul 25 12:05:46 1997 Marius Vollmer <mvo@zagadka.ping.de>
1357 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
1358 SCM_ASSERT: arg comes before pos.
1360 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1362 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
1363 to a list of length zero correctly.
1365 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1367 Supply an `fgets' method for port objects to do fast line i/o.
1368 * ioext.c (scm_read_line): New function.
1369 * genio.c (scm_gen_read_line): New function.
1370 * fports.c (scm_fgets): New function.
1371 (scm_fptob, scm_pipob): Add scm_fgets method.

1379 Mon Jul 21 04:03:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1381 * ioext.h: removed scm_duplicate_port prototype.
1383 * ioext.c (scm_primitive_dup2): return the new file descriptor
1384 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
1386 (scm_fdopen): bug fix: don't try to make port unbuffered until its
1387 stream has been set.
1388 (scm_duplicate_port): deleted, there's now an implementation in
1390 (scm_primitive_dup2): do nothing if newfd == oldfd.
1392 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
1394 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
1397 * ioext.h: new prototypes.
1398 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
1400 * fluids.c (next_fluid_num): don't do
1401 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
1403 * ports.h: prototypes too.
1404 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
1406 * fports.h: prototype too.
1407 * fports.c (scm_evict_ports): moved from ioext.c.
1409 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
1411 * ports.c (scm_close_port): return a boolean instead of unspecified.
1412 throw an error if an error other than EBADF occurs.
1414 * filesys.h: scm_close prototype.
1415 * filesys.c (scm_close): new procedure, can close file descriptors
1416 and ports (scsh compatible).
1418 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
1421 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
1423 * fluids.c, fluid.h: New files.
1424 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
1425 (modinclude_HEADERS): Added "fluids.h"
1427 * init.c: Include "fluids.h". (scm_boot_guile_1): Added call to
1428 scm_init_fluids to initialize the fluid machine.
1429 (scm_start_stack): Initialize the fluids of the first root with
1430 scm_make_initial_fluids.
1432 * root.h: Added "fluids" member to scm_root_state.
1433 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
1434 (scm_make_root): Call scm_copy_fluids to make fluid bindings
1435 unique for the new root when it has a parent.
1437 * smob.h: Include "libguile/print.h" to make scm_print_state
1440 * dynl.c (free_dynl_obj): New function to free the dynamic object
1441 data. (dynl_smob): Use it.
1442 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
1443 the dynamic object data below the linking of the object to avoid
1444 memory leak when the linking code throws an error. Now the code
1445 leaks a whole dynamically linked library when must_malloc throws,
1446 but that should be much less likely.
1448 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
1450 Changes to compile under gnu-win32, from Marcus Daniels:
1451 * stime.c (tzset): If tzset isn't provided, make it a NOP.
1452 (scm_localtime): Change SCM_EOF to SCM_EOL.
1453 (scm_mktime): Likewise.
1454 * socket.c: Don't include sys/un.h unless autoconf tells
1455 us Unix domain sockets are available.
1456 (scm_fill_sockaddr): Ignore Unix domain code.
1457 (scm_addr_vector): Likewise.
1458 (scm_init_addr_buffer): Likewise.
1459 (scm_socketpair): Don't include unless socketpair was

1462 * scmsigs.c (scm_pause): Don't include unless pause was found
1464 * posix.c (scm_getgroups): Don't include unless support function
1465 was found during autoconf (in this case, getgroups).
1466 (scm_setpwent): For setpwent.
1467 (scm_setegid): For setegid.
1468 * net_db.c (scm_inet_netof): Don't include unless support
1469 function was found during autoconf (in this case, inet_netof).
1470 (scm_lnaof): For inet_lnaof.
1471 (scm_inet_makeaddr): For inet_makeaddr.
1472 (scm_getnet): For getnetent, getnetbyname, getnetbyaddr.

1481 Thu Jul 10 00:22:24 1997 Jim Blandy <jimb@floss.red-bean.com>
1483 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
1484 scm_misc_error, not SCM_EOF.
1486 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
1487 arguments for formatting the error message, not SCM_BOOL_F. I
1488 think this is left over from the (eq? '() #f) days.
1490 * read.c (recsexpr): Give this a dummy definition if
1491 DEBUG_EXTENSIONS isn't #defined.
1493 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
1495 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
1498 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>

1503 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
1505 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
1506 alloca.lo will be included in @LIBLOBJS@. Something better than
1507 this should be possible.
1508 * Makefile.in: Regenerated.
1510 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1512 * simpos.h: prototype for scm_primitive_exit.
1513 * simpos.c (scm_primitive_exit): new procedure, terminates the
1514 process without unwinding the stack.
1516 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
1518 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
1519 argument and logior its components together, so the user doesn't
1520 have to do this explicitly. Also, if regexp/basic is supplied, then
1521 turn off REG_EXTENDED.
1522 (scm_init_regex_posix): New regexp/basic symbol.
1523 (REG_BASIC): #define this if it is not already present.
1525 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1527 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
1528 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
1529 (CLEANFILES): New target, clean versiondat.h, libpath.h.
1530 (DISTCLEANFILES): New target, clean *.x.
1531 * Makefile.in: Regenerated.

1535 * script.c (scm_compile_shell_switches): Add 1997 to copyright
1536 years in usage message.
1538 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
1539 * Makefile.in: Regenerated.
1541 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
1542 flag; I don't think we support it.
1543 (scm_make_regexp): Make sure the user doesn't pass the
1546 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
1548 (scm_init_regex_posix): Define constants for the REG_mumble flags;
1549 name them according to the SCSH convention: regexp/mumble.
1551 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
1553 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
1555 * Makefile.am (libpath.h): Include the values of all the standard
1556 Makefile directory variables. Print a message, but don't print
1558 (versiondat.h): Print a message, but don't print all the commands.
1559 * load.c: #include "alist.h".
1560 (init_build_info): New function.
1561 (scm_init_load): Call it.
1562 * Makefile.in: Regenerated.
1564 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
1566 * root.c: Establish a reliable catch-all handler for the new root.
1567 After all the Scheme handler function might signal an error too,
1568 and we don't want to lose that.
1569 (cwdr_inner_body): Renamed from cwdr_body.
1570 (cwdr_outer_body): New function, to establish the user's handler,
1571 and pass control to cwdr_inner_body.
1572 (cwdr): Establish the reliable catch-all handler here, and pass
1573 control to cwdr_outer_body.
1574 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
1575 the user's handler through to cwdr_outer_body.
1576 * throw.c (scm_handle_by_message): Move guts into....
1577 (handler_message): New static function.
1578 (scm_handle_by_message_noexit): New function.
1579 * throw.h (scm_handle_by_message_noexit): New prototype.
1581 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
1582 across this. Only works on GCC. Otherwise, we hope for the best.
1583 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
1584 the feeling that real thread systems will not need this...
1586 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
1588 Try to detect when people are using one version of libguile and a
1589 different version of ice-9. People have been skewing things and
1590 sending in bug reports.
1591 * Makefile.am (versiondat.h): New file to generate.
1592 * version.c: #include "versiondat.h", to get version info.
1593 (scm_libguile_config_stamp): New function.
1594 * script.c: #include "version.h".
1595 (scm_compile_switches): Call scm_version to get version number.
1596 * scmconfig.h.in, Makefile.in: Regenerated.
1597 * Makefile.in: Regenerated.
1599 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
1600 primitive definitions under their Scheme names.
1602 * Makefile.am (libguile_la_LDFLAGS): Update library version to
1603 1:2. Helps avoid confusion between installed and uninstalled libs.
1605 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
1608 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
1609 backslash from definition; this should be used like: GDB_INTERFACE;
1611 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1613 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
1614 new port unbuffered until its stream has been set.
1616 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
1618 * ports.h: new prototype.
1619 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
1621 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
1623 Make things compile neatly under Sun's C compiler.
1624 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
1625 * extchrs.c (xmbtowc): Make the second arg a normal char, not
1626 unsigned, because that's what the ANSI function takes.
1627 * extchrs.h (xmbtowc): Corresponding change to prototype.
1628 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
1630 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
1631 argument plain char *.
1632 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
1634 * tag.c (scm_tag): Remove unreachable statement.
1635 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
1636 top of the word, it should be unsigned.
1638 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
1639 is defined, to avoid warnings; it's only used in the
1640 conflict-checking code. Which might go away anyway.
1641 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
1642 conditionals; put the label definition in an #if too, to stifle
1645 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
1646 ChangeLog-threads in the distribution.
1647 * Makefile.in: Regenerated.
1649 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1651 * guile-snarf.in: Changed regexp to support CPPs that insert
1652 whitespace between lexical tokens (which munges the `%%%' snarf
1655 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1657 * load.c (scm_init_load_path): Append $(datadir)/guile to
1658 %load-path, so modules do not have to be installed in Guile's
1659 current version directory.
1661 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
1663 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
1664 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
1665 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
1666 call the sysdep functions with deferred ints.
1667 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
1668 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
1669 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
1672 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
1675 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
1677 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
1679 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
1681 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
1684 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
1686 * eval.c (scm_lookupcar1): New procedure to cope with a race
1687 condition during lookup (when using threads).
1688 (scm_lookupcar): Implement in terms of scm_lookupcar1.
1689 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
1692 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
1694 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
1695 supplied. (Change from Tim Pierce.)
1697 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
1699 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
1700 23:47:01 1997" changelog: Slots are now initialized with `#f' by
1701 default and not `()'. `#f' is the canonical non-value in Scheme,
1704 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1706 * struct.c (struct_printer): New variable that holds a handle on
1707 the Scheme variable *struct-printer*. This variable can be set by
1708 Scheme code to override the printing of structures.
1709 (scm_print_struct): If struct_printer is set, call it. If it is
1710 not set, or returns #f, print the structure in the old fashion.
1711 Include "eval.h" for scm_apply.
1713 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
1715 * struct.c (scm_struct_ref, scm_struct_set_x): Use
1716 scm_struct_i_n_words to get the number of fields, not
1717 -scm_struct_n_extra_words.
1719 On the route to fancier struct printing:
1720 * struct.c (scm_print_struct): New function to print a structure.
1721 Include "genio.h" to support it. This function doesn't do
1722 anything interesting right now, but I think it should be here
1724 * struct.h: Include "print.h" and add prototype for
1726 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
1727 print structures ourself.
1729 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
1731 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
1732 before applying the handler in case it doesn't return.
1734 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
1736 * scmsigs.h, async.h: updated.
1738 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
1741 * posix.c (scm_uname): interpret only negative values as an error.
1742 Solaris normally returns a positive value.
1744 * script.c (scm_compile_shell_switches): if we are not going into
1745 an interactive repl, set scm_mask_ints to zero so that asyncs can
1748 * simpos.c (scm_system): don't ignore/unignore signals around
1751 * posix.c (scm_open_pipe): don't ignore/unignore signals around
1754 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
1755 done in boot-9.scm instead.
1757 * scmsigs.c, async.c: Major rewriting of signal handling code.
1758 (scm_sigaction): new procedure.
1759 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
1761 (scm_raise): return unspecified, throw error on failure.
1763 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
1765 * regex-posix.c (scm_init_regex_posix): Register the "regex"
1766 feature, to help boot-9.scm decide whether to import the regex
1769 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
1771 * eval.c: Include scmconfig.h at the beginning of the file so that
1772 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
1775 * regex-posix.c: #include "_scm.h" before conditionally #including
1776 <regex.h>; the former defines HAVE_REGCOMP.
1778 * regex-posix.c: #include <regex.h> conditionally, so the file is
1779 CPP'able (for dependency scanning) even on systems that don't have
1782 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
1784 Add new R4RS-compliant syntax for keywords.
1785 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
1786 regardless of the setting of the `keywords' read option.
1787 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
1788 can be re-read no matter what the setting of the `keywords' read
1791 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
1793 Add support for POSIX regular expressions.
1795 * regex-posix.c, regex-posix.h: New files. (Some code
1796 is taken liberally from rx/rgx.c in the old Guile dist.)
1798 * init.c: Include regex-posix.h.
1799 (scm_boot_guile_1): Call scm_init_regex_posix.
1801 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
1802 Add regex-posix.[ch] sources.
1803 * Makefile.in: Regenerated.
1805 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
1806 to do this automatically? It didn't for me, bleh.)
1808 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
1810 * fports.c (print_pipe_port): New function.
1811 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
1812 latter doesn't even take the right arguments.
1814 * Makefile.am: Increment shared lib revision number. I think
1815 sometimes the uninstalled Guile finds the installed shared lib;
1816 Gord says doing this might help. As things turned out, I can't
1817 say whether it does.
1818 * Makefile.in: Regenerated.
1820 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
1821 passing it as the closure argument to scm_boot_guile. (Bill
1824 * ports.c (print_void_port, putc_void_port, puts_void_port,
1825 write_void_port, flush_void_port, getc_void_port, close_void_port,
1826 noop0): Use ANSI prototypes instead of K&R declarations, so the
1827 initialization of void_port_ptob gets aggressively type-checked.
1828 Fix arguments of print_void_port and write_void_port. (Bill

1862 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
1864 * script.c (scm_find_executable): Use prototype-style definition
1865 here; apparently it's not quite right to have const in a prototype
1866 and then use a K&R declaration. I wonder if stuff like this will
1867 go away if we compile with -Wrequire-prototypes, or whatever that
1868 is... (Bernard URBAN)
1870 * scmhob.h: New text from Bernard URBAN.
1872 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
1874 * script.c: Don't #define const on hpux. Configure takes care of
1875 this. (Thanks to Larry Schwimmer.)
1877 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
1878 decide whether to #include <unistd.h>, instead of listing a bunch
1879 of systems. Don't #include stdio twice. Removed dyked-out
1880 definition of scm_find_impl_file.
1882 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
1884 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
1885 library version info to 1:0.

1892 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
1893 throw.c: Update copyright years; these files have been worked on
1894 significantly in 1997, but only had copyright years for 1996.
1895 Also, change name of copyright holder on some from Mikael
1896 Djurfeldt to Free Software Foundation; he has signed papers
1897 assigning the changes to the FSF.
1899 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
1900 reason not to give the user the option.
1902 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
1903 Return #f on end-of-file when scanning table (i.e. when called
1904 with no arguments). Try to catch errors, when we can.
1905 * posix.c (scm_getgrgid, scm_getpwuid): Same.
1907 * script.h (scm_shell_usage, scm_compile_shell_switches): New
1908 external declarations. These are useful.
1910 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
1912 * posix.c: don't include <sys/select.h> or define macros for
1913 select, since they were not used in this file.
1915 * filesys.c (scm_select): make the fifth parameter microseconds,
1916 not milliseconds. let the fourth parameter be either a real value
1917 or an integer or #f. The first, second and third arguments can
1918 now be vectors: the type of the corresponding return set will be
1920 (set_element, get_element): new static procedures.
1922 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
1924 * strports.c (scm_eval_string): New function.
1925 (scm_eval_0str): Trivially re-implemented in terms of
1927 * strports.h (scm_eval_string): New extern decl.
1929 * net_db.c (h_errno): Add extern decl for this.
1931 * fports.c (local_pclose): New function.
1932 (scm_pipob): Use it in the initializer here.
1935 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
1936 Use a meaningful error message when signalling an error. For
1937 this, scm_gethost must check h_errno rather than errno.
1939 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
1941 * Makefile.in: Regenerated, using automake-1.1p.
1943 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
1945 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
1946 not SCM_UNSPECIFIED.
1948 * script.c (scm_compile_shell_switches): don't append (quit) if
1950 (scm_shell): call scm_exit_status and exit on the result of the
1953 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
1955 Ensure that shared substrings are handled properly when passed to
1956 a system call or other foreign function. Many thanks to Tim
1958 * symbols.h (SCM_COERCE_SUBSTR): new macro.
1959 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
1960 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
1961 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

1963 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
1964 (scm_display_error_message): use RO macros when strings may be RO.
1965 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
1966 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
1967 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
1968 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
1969 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
1970 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
1971 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,

1984 * dynl-shl.c: Completely replaced with new code from Bernard
1987 * script.c (scm_ice_9_already_loaded): New variable.
1988 (scm_compile_shell_switches): Use it.
1990 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1992 * filesys.c (scm_input_waiting_p): add missing third argument to
1995 * stime.c (scm_localtime): copy the result of localtime before
1996 calling gmtime in case they share a buffer.
1997 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2000 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2002 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2004 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2006 * Makefile.am (check-local): New target, which causes 'make check'
2007 to run gh_test_c and gh_test_repl, with some trivial input.
2008 * Makefile.in: Rgnrtd.
2010 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>

2015 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2017 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2018 sure how this was supposed to work.
2019 (scm_async_click): don't send SCM_TICK_SIGNAL.
2020 (scm_init_async): don't initialize %tick-thunk.
2022 * the following change doesn't affect the Scheme interface:
2023 gc-thunk is called at the end of garbage collection. however it's
2024 no longer implemented by pretending it's a signal.
2026 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2027 system async corresponding to scm_gc_thunk.
2028 * async.h: declare scm_gc_async.
2029 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2030 gc-thunk directly, instead of going through a signal handler.
2031 (scm_gc_async): new variable, points to the GC system-async.
2032 (scm_init_async): save the GC async as scm_gc_async instead
2033 of using system_signal_asyncs.

2036 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2038 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2039 Don't screw up if we're interrupted.
2040 * Makefile.in: Regeneradet.
2042 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2044 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2046 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2047 we're not using AM_INIT_GUILE_MODULE any more.
2048 * Makefile.in: Reneregated.
2050 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2052 Functions for finding variable bindings, grace à Tim Pierce.
2053 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2054 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2056 Get 'make dist' to work again.
2057 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2058 * Makefile.in: Regenerated, like a surry without a fringe on top.
2060 Changes for reduced Guile distribution: one configure script,
2062 * configure.in, configure: Removed.
2063 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2064 real configure script lives.
2065 * Makefile.in, scmconfig.h.in: Regenerated.
2067 * init.c: #include "script.h", to get prototype for script.c's
2070 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2072 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2073 scm_must_malloc, not raw malloc.
2075 * script.c (scm_compile_shell_switches): Dyke out debugging output
2078 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2080 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2082 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2083 system has them. Hope this is safe. Previously
2084 sys/timeb.h was included if HAVE_FTIME was defined or if
2085 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2086 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2088 * ioext.c (scm_setfileno): add missing third argument to
2089 scm_misc_error call.
2091 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2093 * eq.c (scm_equal_p): Correctly compare strings of different
2094 varieties. (Thanks to Tim Pierce.)
2096 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2098 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2099 #! block comment must occur on a line all by itself.
2101 Move most of the guts of shell command processing into libguile,
2102 so guile.c can be very small (and eventuallly auto-generated. (I
2103 mean, generated mechanically, not self-generated. Hmm.))
2104 * guile.c, script.c, script.h: New source files.
2105 * init.c (scm_boot_guile_1): Call scm_init_script.
2106 * libguile.h: #include "script.h".
2107 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2108 targets, for new executable.
2109 (libguile_la_SOURCES): Mention script.c.
2110 (modinclude_HEADERS): Add script.h.
2111 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2112 not dynamic linking is enabled. This is because we're generating
2113 executables now. Move CY_AC_WITH_THREADS call after those, so the
2114 values of cy_cv_threads_libs captures the libs chosen above.
2115 * Makefile.in, configure, aclocal.m4: Regenerated.
2117 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2118 We don't maintain this interface any more, and it just confuses
2121 * alloca.c: #include <scmconfig.h>, not <config.h>.
2122 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2123 it'll get included in disties.
2125 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2127 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2128 be distributed, because they confuse people.
2129 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2131 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2133 * configure.in: check for presence of gethostent (not present on
2134 OpenBSD by default).
2135 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2136 * configure, scmconfig.h.in: Regenerated.
2138 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2140 * backtrace.c (scm_backtrace): Split message string across
2141 newlines properly. GCC is more tolerant of this than other

2150 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2152 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2153 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2154 coop-threads.c.cygnus, coop-threads.h.cygnus.
2155 * configure.in: If we're using threads, include threads.o in
2157 * _scm.h, libguile.h: threads.h lives in this directory now.
2158 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2159 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2160 currently used, but brought along for information's sake.
2161 * ChangeLog-threads: log from old 'threads' directory.
2162 * Makefile.in, configure: Rebuilt.
2164 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2166 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2169 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2171 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2173 Merge GH interface library into libguile.

2175 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2176 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2177 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2179 (EXTRA_libguile_la_SOURCES): ... here.
2180 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2181 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2182 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2183 New variables, describing how to build the gh test programs.
2184 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2185 build the test programs, and we probably should have been linking
2186 libguile.la against them all along, to support AIX shared libs.
2187 Add cflags for threads to CFLAGS; add libs for threads to new
2188 variable THREAD_LIBS, used in Makefile.am.
2189 * ChangeLog-gh: log from old `gh' subdirectory.
2190 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2192 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2194 * acconfig.h: Undo change of Apr 9; including the definition of
2195 PACKAGE in the guile headers conflicts with applications' own
2197 * scmconfig.h.in: Regenerated.
2199 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

2206 when PROC is receiving no arguments.
2208 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2210 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2211 have S_IFSOCK. This is the case under Ultrix.
2213 * posix.c (scm_status_exit_val, scm_status_exit_val,
2214 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2215 Ultrix versions of WIFSTOPPED, etc., which assume that their
2216 arguments are lvalues (hmm).
2218 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2220 * eval.c: Doc fixes.
2222 * throw.c: Doc fixes; rearranged.
2224 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.

2228 * acconfig.h: Added entry for PACKAGE.
2229 * scmconfig.h.in: Regenerated.
2231 Changes to work with automake-1.1n, which has better libtool support.
2232 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2233 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
2235 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
2237 * Makefile.in: Rebuild.
2239 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2241 * stime.c (scm_mktime): take an optional zone argument.
2242 (scm_localtime): check putenv return value.
2243 (scm_strftime, scm_strptime): moved from posix.c. move #include
2245 stime.h, posix.h: update prototypes.
2246 (bdtime2c, setzone, restorezone): new static procedures.
2247 (scm_mktime, scm_strftime): use them.
2248 (scm_strftime): don't call mktime before strftime. Use
2249 filltime for return value.
2250 (filltime): convert NULL zname to #f.
2251 (scm_strptime): return a count of characters consumed, not
2252 the remaining string.
2254 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2256 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
2257 (scm_mktime): likewise.
2259 Uncomment localtime and mktime.
2261 * configure.in: add AC_STRUCT_TIMEZONE.
2263 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2265 * stime.c (scm_init_stime): don't define ticks/sec.
2266 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2267 return value problem and is still portable.)
2269 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2271 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2272 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2273 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2274 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2275 cpp_err_symbols.c): Corresponding changes.
2276 * Makefile.in: Regenerated.
2278 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2280 * posix.c (scm_putenv): don't check HAVE_PUTENV.
2281 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
2282 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
2283 * putenv.c: new file, from sh-utils 1.12.
2285 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2286 since allocation isn't for Scheme objects.
2287 (scm_putenv): copy strings before placing in the environment.
2289 * stime.c (scm_current_time): throw an error if time returns -1,
2290 instead of returning #f.
2291 (scm_get_internal_real_time, scm_get_internal_real_time): use
2292 scm_long2num for return value instead of SCM_MAKINUM.
2294 * stime.h: prototypes updated.
2296 * stime.c (scm_time_in_msec): apparently unused, deleted.
2298 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2300 * configure.in: check for gettimeofday.
2302 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2303 which may be more usefully portable than a gettimeofday interface.
2305 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2307 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not

2311 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2313 * stime.c (filltime): recovered static procedure.
2314 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
2317 * posix.h: add prototype for scm_close_pipe, remove prototypes for
2318 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2320 * posix.c (scm_mknod): split the mode argument into type and perms
2321 arguments, like the extra fields returned by stat.
2323 * fports.c (scm_pipob): set the close, free and print procedures.
2324 (scm_close_pipe): new procedure.
2326 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2327 define them in boot-9.scm
2329 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2331 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
2332 wan't defined. Don't include fd.h.
2334 * Previously fd.h was regenerated whenever configure was run,
2335 forcing a couple of files to be recompiled.
2337 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
2338 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
2339 Check for _fileno as well as _file.
2341 * ioext.c: don't fd.h.
2342 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
2345 * Change the stratigy for getting information about errno
2346 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
2347 generating lists of symbols during the build process, which will
2348 not always work, include comprehensive lists in the distribution.
2349 To help keep the lists up to date, the "check_signals" and
2350 "check_errnos" make targets can be used.
2352 * configure.in: don't check for a command to extract errno codes.
2353 * Makefile.am: update file lists, remove errnos.list and errnos.c
2354 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
2355 check_errnos targets.
2356 (CLEANFILES): remove errnos.c and errnos.list, add
2357 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
2358 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
2359 * errnos.default: deleted.
2360 * cpp_signal.c: new file.
2361 * cpp_errno.c: renamed from errnos_get.c.
2362 * cpp_err_symbols, cpp_sig_symbols: new files.
2363 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
2364 * error.c (scm_init_error): #include cpp_err_symbols instead of
2366 * posix.c (scm_init_posix): don't intern signal symbols. #include
2369 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
2371 * strop.c (scm_i_index): allow the lower bound to be equal to the
2372 length of the string, so a null string doesn't always give an error.
2374 * posix.h: new prototypes.
2375 * posix.c (scm_status_exit_val, scm_status_term_sig,
2376 scm_status_stop_sig): new functions, as in scsh. They break down
2377 process status values as returned by waitpid.
2379 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
2381 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
2382 configure doesn't know about it.
2384 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2386 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
2388 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
2389 which defines C variables with global linkage.
2391 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2393 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
2396 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
2398 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
2399 has time to check why this doesn't work well with continuations.
2401 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
2403 * Fix shell syntax error; some shells won't tolerate
2404 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
2406 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2408 * posix.c (scm_uname): throw an error if uname fails instead
2411 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
2413 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
2416 * async.c (scm_ints_disabled): definition moved from error.c.
2418 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2420 * acconfig.h: Removed PACKAGE.
2422 * scmconfig.h.in: Regenerated.
2424 * snarf.h: g++ says it's non-portable not to specify the first
2425 argument in a varargs declaration. I introduced the first
2426 argument by using preprocessor conditionals.
2428 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
2430 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
2431 (scm_freopen): use RO string macros for filename and modes.
2432 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
2434 * posix.c (scm_getgrgid): simplify conversion of name to C string.
2435 (scm_mknod): use RO string macros for path.
2437 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
2438 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
2440 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2441 use SCM_ROSTRINGP and SCM_ROCHARS.
2443 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2445 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
2448 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
2449 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
2450 support for byte vectors.
2452 * print.c (scm_iprin1): Limit number of vector elements printed
2453 according to pstate->length.
2455 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2457 * backtrace.c (scm_display_error_message): don't segv if message
2460 * error.h: prototype for scm_error_scm.
2462 * error.c (scm_error_scm): new procedure, reimplements scm-error
2463 in C and uses scm_error.
2465 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2467 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
2468 pointer to the Scheme variable read-hash-procedures and intern it
2469 in scm_init_read. Modify scm_read_hash_extend and
2470 scm_get_hash_procedure to use the pointer.
2472 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2474 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
2475 (SCM_KEYWORD_STYLE): defined.
2477 * read.c (scm_read_opts): add a keywords option. This isn't a
2478 boolean option, in case someone wants to add support for DSSSL
2480 Setup scm_keyword_prefix symbol.
2481 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
2483 I've left keyword support disabled by default, since it doesn't
2484 seem to break the module system and it gives R4RS standard behaviour.
2485 It can be reactivated with (read-set! keywords 'prefix).
2487 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2489 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
2490 before constructing arbiter.
2492 * eval.c (scm_m_define): Bugfix: Check that the object is a
2493 closure before setting the procedure property!
2495 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
2497 * ports.c: Removed `ungetc-char-ready?'.
2499 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
2501 * read.c (scm_init_read): intitialise scm_read_hash_procedures
2502 (idea from Mikael: make it a pair so scm_permanent object only
2504 (scm_read_hash_extend): don't call scm_permanent_object.
2505 (ideas from Mikael): if chr is already in the list, replace its
2506 procedure instead of appending it again. If proc is #f, remove
2508 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
2510 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
2512 * gdbint.c (gdb_read): update scm_lreadr usage.
2514 * load.h: update prototypes.
2516 * load.c (scm_primitive_load, scm_read_and_eval_x,
2517 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
2519 * read.h: add prototype for scm_read_hash_extend. Change args for
2522 * read.c (scm_read_hash_procedures): new variable.
2523 (scm_read_hash_extend): new procedure.
2524 (scm_get_hash_procedure): new procedure.
2525 (scm_lreadr): use scm_get_hash_procedure instead of an argument
2526 for extended # processing.
2527 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
2528 scm_read_token): remove case_i, sharp arguments. Change callers.
2530 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
2532 * read.h (SCM_N_READ_OPTIONS): increase to 3.
2533 (SCM_CASE_INSENSITIVE_P): define.
2535 * read.c: add case-insensitive option to scm_read_opts.
2536 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
2537 to determine whether to convert symbol case.
2538 (default_case_i): definition removed.
2539 * read.c (scm_read_token): if case_i, downcase ic before doing
2542 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2544 * configure.in: Added configuration option `guile-debug'.
2545 Configure with --enable-guile-debug if you want a bunch of extra
2546 functions used for debugging when developing Guile.
2548 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
2550 * procs.c (make-cclo): New undocumented debugging procedure: Make
2551 compiled closure with internal procedure PROC and length LENGTH.
2552 Only compiled if GUILE_DEBUG is defined.
2554 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
2556 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
2558 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
2560 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
2561 with 3 or more args internally to the evaluator.
2563 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2565 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
2566 with 3 or more args internally to the evaluator. This is mainly
2567 because we don't want to pass entry and exit points of the
2568 debug support twice, but it also seems to increase the speed of
2569 the evaluator for such calls (e. g. (+ 1 2 3)).
2571 * backtrace.c (scm_display_application): New procedure:
2572 display-application; Set fancy printing parameters individually
2573 for different types of display (backtrace, error, application).
2574 (These should of course be customizable!)
2576 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
2577 clear the CHECK-flags.
2579 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2581 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
2583 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2585 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
2586 from pairs with a GLOC in the car.
2588 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
2589 otherwise `symbol-hash' will behave badly.
2590 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
2591 we get segmentation fault!
2593 * symbols.c: Added #include "weaks.h". New functions:
2594 `builtin-bindings' and `builtin-weak-bindings'. (These will be
2595 moved to an extraneous library when we split libguile.)
2597 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2599 * filesys.c (scm_stat): stat now takes fport arguments too as
2600 documented in the manual.
2602 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2604 * debug.c (scm_single_step): Bugfix: Call continuation with
2605 scm_call_continuation instead of throwing to it.
2607 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
2609 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
2610 argument wasn't declared to be optional.
2612 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2614 * stime.c (scm_init_stime): Add feature "current-time".
2616 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
2618 * throw.h: prototype for scm_exit_status.
2619 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
2620 args to derive an exit status. Allows (quit) to work from a
2622 (scm_exit_status): new function.
2625 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2627 * eval.c (scm_deval): Removed some old code.
2628 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
2630 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
2633 * symbols.c (msymbolize): Bugfix: Must initialize property list to
2636 * procs.c: Introduce the existent C function scm_thunk_p at the
2637 Scheme level as well.
2639 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2641 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
2642 used from C to easily lookup the value of a symbol in the current
2645 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2647 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
2648 scm_init_unif in this file. This will also fix a previous problem
2651 * configure.in: Added AM_MAINTAINER_MODE
2653 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2655 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
2658 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
2660 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
2661 source files that are not always included in libguile but should
2662 have their dependencies calculated by automake. This variable is
2663 recognized by automake, no further magic is needed.
2664 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
2665 to deal exclusively with *.lo files, as it seems. The *.o files
2666 are built automatically when the corresponding *.lo file gets
2669 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
2671 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
2674 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
2676 * unif.c (scm_array_set_x): minor change to argument error checking.
2678 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
2680 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
2681 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
2682 They should only be included in the library at configure.in's
2684 (libguile_la_LDADD): Include the appropriate .lo files here.
2685 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
2686 so we know when to build them (and their .lo bretheren).
2687 * configure.in (LIBLOBJS): New substituted variable. We let
2688 configure decide which .o files to include in LIBOBJS, and then
2689 put the corresponding list of .lo files in LIBLOBJS. The latter
2690 is what we pass to libtool.
2691 * Makefile.in, configure: regenerated.
2693 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
2695 * symbols.c (scm_sysintern0): New function. Contains the core of
2696 old scm_sysintern but doesn't take a second value argument.
2697 (scm_sysintern): Now uses scm_sysintern0.
2698 (scm_sysintern_no_module_lookup): Renamed to
2699 scm_sysintern0_no_module_lookup and doesn't take a second value
2700 argument any longer.
2702 * symbols.h (scm_sysintern0: Added declaration.
2704 * options.c (scm_init_opts): Use scm_sysintern0 instead of
2705 scm_sysintern when interning option keys. Otherwise we risk
2706 destroying the values of already interned variables.
2708 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
2709 scheme-level boolean (use SCM_NFALSEP).
2711 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
2713 (scm_backtrace): New function. (C version of old function from
2714 boot-9.scm) Motivation: Make it possible to display backtraces
2715 without depending on boot-9.scm. (I'm uncertain if this
2716 motivation is good enough...)
2718 * root.h (scm_root_state): Add member the_last_stack_var.
2719 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
2721 * root.c (mark_root): Mark scm_the_last_stack_var.
2723 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
2726 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
2728 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
2729 1. mark_lazy_catch didn't mark the smob.
2730 2. Both functions above have standard variants:
2731 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
2732 free_lazy_catch --> scm_free0.
2734 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
2736 * throw.c (scm_internal_lazy_catch): New function.
2737 (scm_lazy_catch): Rewritten to use it.
2738 (scm_ithrow): Handle the new lazy catch representation.
2739 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
2740 that doesn't have a jmpbuf is a lazy catch clause.
2741 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
2742 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
2743 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
2745 (scm_init_throw): Register the new lazy-catch smob type.
2746 * throw.h (scm_internal_lazy_catch): decl for new function.
2748 * throw.c (scm_internal_catch): Doc fixes.
2750 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
2751 configure.in. Including this might cause problems if applications
2752 that link against libguile include their own copies of alloca, but
2753 if they're using autoconf, they should be adding libguile to LIBS
2754 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
2755 the copy in libguile, and things will be okay. (I think.)
2757 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2759 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
2761 strop.h: move prototypes too.
2763 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2765 * posix.c (scm_init_posix): don't intern EINTR since it's now done
2768 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
2769 etc. I deleted them from filesys.c long ago, but didn't
2770 notice they were here too (although ineffective since
2771 sys/stat.h wasn't included).
2773 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
2775 * eval.c: Don't define alloca in GCC case. gcc will automatically
2776 use __builtin_alloca if appropriate.
2778 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2780 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
2781 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
2782 that values of automatic variables are preserved. See comments
2783 for safe_setjmp for details.
2785 Change from Thomas Morgan:
2786 * variable.c: Include eq.h.
2787 (var_equal): New function.
2788 (variable_smob): Use var_equal as the discriminator for variables.
2790 * throw.c (s_throw): Remove extraneous declaration.
2792 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
2793 * eval.c: Add necessary CPP cruft to support that.
2794 * configure, Makefile.in, scmconfig.h.in: regenerated.
2796 Change from Thomas Morgan:
2797 * procprop.c (scm_procedure_properties): Convert the Scheme
2798 boolean returned by scm_procedure_p into a C boolean before using
2799 it as a condition for SCM_ASSERT.
2800 (scm_procedure_property): Likewise.
2802 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
2803 indications of Unixness.
2806 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2808 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
2810 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2812 * read.c (scm_lreadr): use scm_misc_error to improve one of the
2813 "unknown # object" error messages.
2815 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
2816 (scm_i_index) and declare it static. Add a 'direction' argument
2817 to indicate what way the search should go.
2818 (scm_i_index): throw out-of-range error instead of wrong-type-arg
2820 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
2821 strop.h: remove scm_i_index, scm_i_rindex prototypes.
2823 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2825 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
2827 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
2828 to avoid clash with various scsh forks.
2830 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
2832 The following two changes (ramap.c, throw.c) are motivated by the
2833 apparent unportability of forward declarations of static arrays of
2834 the form `static foo bar[];'.
2836 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
2837 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
2839 * throw.c (scm_throw): Moved above scm_ithrow.
2841 * options.h: Removed the extern declarations of scm_yes_sym and
2842 scm_no_sym since these are static.
2844 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2846 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
2848 * Makefile.am: remove AWK=@AWK@.
2849 Add a rule for generating errnos.list.
2850 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
2852 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
2853 don't extract errnos, just set a variable (avoids the
2854 need to recompile error.c just because configure is run.)
2856 * unif.h: update prototypes.
2857 * unif.c (scm_uniform_array_read,write): change the offset and
2858 length arguments to start and end, for consistency.
2860 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
2862 * ioext.h: update prototypes.
2863 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
2864 scm_read_line_x, it's a more general procedure using an
2865 interface from scsh. read-line and read-line! are now defined
2867 Note that the new read-line trims the terminator
2868 by default, previously it was appended to the returned string. An
2869 optional argument specifies how to process the terminator (scsh
2870 compatible). For the old behaviour: (read-line port 'concat).
2871 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
2872 returns a pair, but is converted to multiple values if the scsh
2875 socket.h: update prototypes.
2876 * socket.c (scm_recvfrom): for consistency with other procedures,
2877 take start and end as separate optional arguments.
2878 (scm_recv, scm_recvfrom): don't allow the second argument
2879 to be a size, only a buffer. Change the scheme names to
2880 recv! and recvfrom!. Don't return the buffer.
2882 * ioext.h, posix.h: move prototypes too.
2883 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
2884 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
2885 "read.h" and "unif.h".
2886 * ioext.c: include "chars.h"
2888 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
2890 * dynl.c: The dynamic linking and module registration functions
2891 are now defined even when dynamic linking is not available for the
2892 host system. Some of their functionality can be done without
2893 dynamic linking; when it's really needed, they throw errors.
2895 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
2897 * configure.in: Only define DYNAMIC_LINKING when one of the system
2898 dependent functions is detected.
2899 * dynl.c (scm_dynamic_func): New function to get the address of a
2900 function in a dynamic object.
2901 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
2902 produced by scm_dynamic_func as the thing to call.
2904 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
2906 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
2907 (scm_register_module_xxx, scm_registered_modules,
2908 scm_clear_registered_modules): New functions.
2910 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
2912 * symbols.c (scm_sysintern): Renamed to
2913 scm_sysintern_no_module_lookup.
2914 (scm_sysintern): New function to take the place of the old
2915 scm_sysintern. It uses the current toplevel lookup closure to give
2916 the symbol its value. This is a temporary hack to put packages
2917 like gtcltk into their own module.
2918 (scm_can_use_top_level_lookup_closure_var): New variable to tell
2919 us whether `scm_top_level_lookup_closure_var' has been initialized
2921 * eval.c (scm_init_eval): Set it.
2923 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
2925 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
2926 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
2928 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
2930 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
2931 scm_sys_dup): deleted: FD capability will be added to other
2933 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
2934 scm_fd_free, fd_smob, scm_intern_fd.
2935 (scm_open): renamed from scm_sys_open. Return a port instead of
2936 an FD object. Make the mode argument optional.
2937 (scm_sys_create): deleted, it's just a special case of open.
2938 (scm_init_filesys): move interning of constants O_CREAT etc.,
2939 here (were previously using SCM_CONST_LONG macro).
2940 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
2942 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
2943 include "fports.h" and <stdio.h>
2944 (scm_stat, scm_select): don't support FD objects.
2946 * error.h: adjust scm_syserror_msg prototype.
2947 * error.c (scm_syserror_msg): take an extra argument for errno.
2948 Using the global value didn't always work, since it could be
2949 reset by procedure calls in the message or args arguments.
2951 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
2952 I don't understand why the check was there (and what about the
2955 * strop.c (scm_string_copy): allow shared substrings to be copied.
2957 * unif.h: corresponding change to prototypes.
2958 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
2959 recognize two new optional arguments: offset and length. Allow
2960 the port argument to be an integer (file descriptor, for scsh).
2961 Include <unistd.h> for "read" prototype.
2963 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2965 * socket.c: don't include filesys.h.
2967 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
2969 * Makefile.am: add AWK=@AWK@ (?)
2971 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
2973 Add a rule to generate errnos.c from errnos.
2974 * error.c (scm_init_error): include errnos.c.
2975 * errnos_cnvt.awk: new file, converts the list of errno codes to
2977 * errnos_get.c: new file.
2978 * errnos.default: new file, contains errnos to try if they can't
2979 be extracted from errno.h.
2980 * configure.in: if using GCC, try and extract errno codes from
2984 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
2986 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
2987 * Makefile.am: Made libguile into a libtool library.
2988 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
2989 Set libtool_libs to indicate that libguile is a libtool library.
2990 See guile/ChangeLog for details.
2991 * .cvsignore: ignore "*.lo", the libtool library objects.
2993 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2995 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
2996 use htons in getservbyport argument.
2998 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3000 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3001 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3004 * objprop.c (scm_object_property): No need to take the CDR of the
3005 value returned by scm_object_properties, since Aug 20 change.
3007 * configure.in: When checking for struct linger, #include
3008 <sys/types.h> as well as <sys/socket.h>. I've never known
3009 <sys/types.h> to cause any portability problems, and Solaris's
3010 <sys/socket.h> needs it.
3011 * configure: Rebuilt.
3013 I think the Sun compiler has chosen a perverse way to interpret
3014 ANSI declarations combined with K&R definitions. We'll
3015 appease it a little bit. But when it invades France, we fight.
3016 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3017 * print.h (scm_iprlist): Here too.
3018 * numbers.c (scm_divbigdig): Change definition to match
3019 declaration in numbers.h.
3020 * unif.c (scm_makflo): Change definition to match declaration in
3023 * init.c (scm_boot_guile): Don't return the value of
3024 scm_boot_guile_1. This function doesn't return a value;
3025 scm_boot_guile_1 doesn't return a value (or return at all).
3027 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3030 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3031 compile. I have a feeling this function is a bad idea anyway ---
3032 one should always test for features, not systems.
3034 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3035 semicolons. Only pure luck kept this from being noticed earlier.
3037 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3039 * socket.c (scm_recvfrom): Added missing semicolon.
3041 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3043 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3044 the buffer and start and end positions for scsh networking
3047 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3049 * configure.in: Revert previous change to this file; the problem
3050 is due to transient automake weirdness.
3051 * configure: Rebuilt.
3053 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3054 PLUGIN/guile.libs. configure generates the latter from the former.
3055 * Makefile.in: Rebuilt.
3057 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3058 need this if we install scripts, like guile-snarf.
3059 * configure: Rebuilt.
3061 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3063 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3065 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3067 * socket.c (scm_addr_vector): fix faulty scm_listify.
3069 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3071 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3072 style block comment is no longer considered an error.
3074 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3076 * PLUGIN/guile.libs.in: New file.
3077 * PLUGIN/guile.libs: Removed from repository.
3078 * configure.in: Create PLUGIN/guile.libs from
3079 PLUGIN/guile.libs.in. This is for including additonal libraries
3080 needed for dynamic linking.
3081 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3082 instead of PLUGIN/guile.libs.
3084 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3086 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3088 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3089 occurrences of the given element from the list, not just the
3090 first. This is how the Emacs Lisp functions behave, how the
3091 analogous Common Lisp functions behave, and (I believe) how the
3092 older Maclisp functions worked. I realize that this change may
3093 break code, but it seemed better to break it before the Guile
3096 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3097 Their prototypes were already present in gc.h, but they weren't
3099 (scm_init_storage): Initialize scm_protects.
3100 * root.c (scm_protects): New element of scm_sys_protects.
3102 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3104 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3106 * libguile.h: Added #include "libguile/net_db.h".
3108 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3109 30 change. That file is only meant for communication between the
3110 configuration process and load.c. If code linked against libguile
3111 wants to get at the paths mentioned in libpath.h, it can call
3112 functions declared in load.h.
3114 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3116 * libguile.h: Removed #include "libguile/fdsocket.h"
3118 * net_db.c: Added #include <sys/socket.h>.
3120 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3122 * filesys.c (scm_input_waiting_p): use select in preference to
3123 FIONREAD, since the latter doesn't detect EOF.
3124 Throw error if neither select nor FIONREAD available.
3126 * socket.c (scm_connect): take a port, not a fd object.
3127 (scm_fill_sockaddr): throw an error if fam is not recognised.
3128 (scm_bind): use scm_fill_sockaddr.
3129 (scm_listen): take a port, not a fd object.
3130 (scm_accept): take and return a port. return #f in the car if
3131 address can't be got
3132 (scm_sock_fd_to_port): new procedure.
3133 (scm_socket): use scm_sock_fd_to_port.
3134 (scm_addr_vector): throw error if unrecognised address type.
3135 take an extra argument with the calling procedure name.
3136 (scm_getsockname): take a port. return #f if address can't be got.
3137 (scm_getpeername): take a port. return #f if address can't be got.
3138 (scm_recvfrom): take a port. return #f for address component if can't
3140 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3141 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3143 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3145 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3146 use separate data pointers, to allow them to be designed
3147 independently and reused.
3148 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3149 Renamed from catch_body, catch_handler, and uncaught_throw; made
3151 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3153 (scm_catch): Use the above.
3154 (scm_throw): Don't bother printing a message for an uncaught
3155 throw; we establish a default handler in init.
3156 * throw.h (scm_internal_catch): Prototype updated.
3157 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3159 (struct scm_body_thunk_data): New structure, used as data
3160 argument to scm_body_thunk.
3161 * init.c (struct main_func_closure): New structure, packaging up
3162 the data to pass to the user's main function.
3163 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3164 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3165 scm_internal_catch to establish a catch-all handler, using
3166 scm_handle_by_message. This replaces the special-case code in
3168 (invoke_main_func): Body function for scm_internal_catch; invoke
3169 the user's main function, using the main_func_closure pointer to
3170 decide what to pass it.
3171 * root.c (struct cwdr_body_data): Remove handler_proc member.
3172 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3173 (cwdr_handler): Removed.
3175 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3177 * socket.h (SCM_P): update bind prototype.
3178 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3179 include "feature.h".
3180 (scm_socket): return a port, not a file descriptor object.
3181 include "fports.h" and <unistd.h>
3182 (scm_bind): take a port, not a file descriptor object.
3183 take an extra argument for address args.
3185 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3186 INADDR_NONE, INADDR_LOOPBACK.
3188 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3190 * init.c: include net_db.h and not fdsocket.h.
3191 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3193 * Makefile.am: corresponding changes.
3194 * socket.h: renamed from fdsocket.h, fix names.
3195 * net_db.h: renamed from socket.h, fix names.
3196 * socket.c: renamed from fdsocket.c.
3197 remove _sys from procedure names.
3198 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3199 add "socket" to features list.
3200 * net_db.c: renamed from socket.c.
3201 remove _sys from procedure names.
3202 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3203 add "net-db" to features list.
3204 include "net_db.h". don't include <sys/socket.h> or
3207 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3209 * tags.h (scm_tags): Removed comma at end of last enumerator.
3211 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3213 Don't use GCC extensions to allocate space for debugging frames.
3214 (Here he goes again! Why do we put up with this?!)
3215 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3216 an scm_debug_info structure, not an in-line array of them. Add
3217 'info' member, to say how many vect elements we've used, for eval
3219 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3220 a new variable debug_info_end to mark the end of vect, instead of
3221 the address of the 'info' pointer itself.
3222 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3223 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3224 (SCM_APPLY): Explicitly allocate space for debug.vect.
3225 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3226 * stacks.c: Adjusted for new debug frame structure.
3227 (RELOC_INFO, RELOC_FRAME): New macros.
3228 (stack_depth, read_frames): Use them, and new scm_debug_frame
3229 element 'info', instead of magically knowing that eval frames have
3230 an info pointer sitting after vect.
3231 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3233 (scm_init_stacks): Formatting tweaks.
3235 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3237 Give GCC more control flow information, so it can be sure that
3238 variables aren't used uninitialized.
3239 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3240 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3241 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3242 scm_misc_error): Tell GCC that these functions never return.
3243 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3244 out the field type, call abort if SCM_ASSERT returns, to placate
3246 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3247 scm_wta ever returns. We can't handle this case anyway, and this
3248 gives the optimizer more information.
3249 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3250 scm_wta ever returns.
3252 In some cases, the code is fine, but GCC isn't smart enough to
3253 figure that out; this usually happens when one variable is only
3254 initialized and used when a particular condition holds true, and
3255 we know that condition will never change within a given invocation
3256 of the function. In this case, we simply initialize the variables
3257 to placate the compiler, hopefully to a value which will cause a
3258 crash if it is ever actually used.
3259 * print.c (scm_iprin1): Initialize mw_pos.
3260 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3261 * throw.c (scm_ithrow): Initialize dynpair.
3262 * unif.c (scm_uniform_vector_ref): Initialize cra.
3263 * struct.c (init_struct): Initialize prot.
3264 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3266 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3267 if EXPR contains no expressions.
3269 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3271 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3272 cause an infinite loop (???). So much for the algebraic
3273 equivalency of variable-sized arrays and alloca...
3275 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3277 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3278 a SCM boolean, not a C boolean.
3280 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3282 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3283 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3284 rules for raising scm_mtrigger. Previously, unfortunate but not
3285 unlikely circumstances could result in almost constant invokation
3286 of the gc. Now, this situations should be less likely, but they
3287 are not prevented completely.
3289 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3291 * numbers.c (scm_fuck): Procedure removed; looks like old test
3293 * numbers.h: Prototype removed.
3295 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3297 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3298 array to a pointer, to match my Nov 21 change in eval.c.
3300 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3302 * libguile.h: Added #include "libguile/backtrace.h", #include
3303 "libguile/stacks.h".
3305 * strings.c (scm_string scm_make_string scm_string_ref
3306 scm_string_set_x scm_string_equal_p scm_string_append):
3307 Bugfix according to scm patch from Aubrey Jaffer:
3308 Corrected long-standing
3309 (not (eqv? (integer->char 128)
3310 (string-ref (make-string 1 (integer->char 128)) 0)))
3311 bug found by John Kozak <jk@noontide.demon.co.uk>.
3313 * strports.c, strports.h: Make scm_eval_0str return the value of
3314 the last expression evaluated (previously, it returned void).
3316 * strports.c, strports.h: New function: scm_read_0str. Does what
3319 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3321 * simpos.c (scm_getenv): return #f if string can't be found in the
3322 environment instead of throwing an exception, for compatibility
3323 with numerous other systems.
3325 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3327 * Makefile.am (.c.x): Use guile-snarf.
3328 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
3330 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
3332 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3334 * backtrace.c (scm_display_error_message): Made non-static, and
3335 renamed from display_error_message.
3336 * backtrace.h (scm_display_error_message): Added extern decl.
3337 * throw.c (uncaught_throw): Use it to display the error message.
3339 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
3341 * inet_aton.c: Use #if 0, not #ifdef 0.
3343 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
3345 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
3346 to convert the returned value.
3347 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
3348 the offset argument.
3350 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3352 Add new interface to catch/throw, usable from C as well as
3354 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
3355 (scm_internal_catch): New function, replaces...
3356 (scm_catch_apply): Deleted.
3357 * throw.c (scm_catch_apply): Deleted; replaced with a more general
3358 mechanism which is a bit more code, but can be used nicely from C
3359 and implement the Scheme semantics as well.
3360 (scm_internal_catch): This is the replacement; it's named after
3361 the analogous function in Emacs.
3362 (scm_catch): Reimplemented in terms of the above.
3363 (struct catch_body_data, catch_body, catch_handler): New
3364 functions, used by scm_catch.
3365 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
3366 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
3367 support for new cwdr.
3369 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
3372 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
3374 * acconfig.h: Added DYNAMIC_LINKING symbol.
3375 * configure.in: Add option and checks for dynamic linking.
3376 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
3377 dynl.h: New files for dynamic linking support.
3378 * Makefile.am (libguile_a_SOURCES):
3380 (modinclude_HEADERS): Added "dynl.h".
3381 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
3383 * init.c (scm_boot_guile_1): Call
3384 scm_init_dynamic_linking to initialize dynamic linking support.
3386 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
3388 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
3389 (as we Schemers say). It needs to be global, so that I can tweak
3390 it for the proper operation of unexec.
3391 (scm_boot_guile_1_live): New variable, see above.
3393 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
3395 * guile-snarf.sh: Removed.
3396 * PLUGIN/guile.libs: Added dependency for -lm.
3397 * acinclude.m4: Renamed from aclocal.m4.
3398 * PLUGIN/greet: Removed.
3399 * Makefile.am, aclocal.m4: New files.
3400 * configure.in: Updated for Automake.
3402 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
3404 * eval.c (scm_definedp): Use top_level_lookup_closure_var
3405 and not top_level_lookup_thunk_var.
3407 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
3409 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
3411 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
3413 * eval.c (scm_definedp): Incompatibly changed to be a builtin
3414 Scheme function, instead of syntax. Single argument is now a
3417 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3419 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
3420 scm_ra_divide): Properly terminate statements passed as arguments
3421 to IVDEP macros. (Thanks to Bernard Urban.)
3423 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
3424 with non-constant sizes. (Thanks to Bernard Urban.)
3426 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3428 It's an "eval closure", not an "eval thunk." A thunk is a
3429 function of no arguments.
3430 * root.h (struct scm_root_state): Renamed
3431 top_level_lookup_closure_var from top_level_lookup_thunk_var.
3432 (scm_top_level_lookup_closure_var): Renamed from
3433 scm_top_level_lookup_thunk_var.
3434 * root.c (mark_root): Uses changed.
3435 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
3436 * init.c (scm_start_stack): Uses changed.
3437 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
3438 Change scheme-visible name to *top-level-lookup-closure* from
3439 *top-level-lookup-thunk*.
3441 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
3443 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
3444 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
3446 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
3448 * gc.c (struct scm_heap_seg_data): Doc fixes.
3450 * gc.c (scm_gc_sweep): Empty all segments' freelists before
3451 sweeping. Then, prepend each segment's free cells to its
3452 freelist, rather than wiping out the old value. (Thanks to Marius
3455 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
3456 scm_check_freelist, scm_debug_newcell): New functions and
3457 variables, for debugging freelist problems.
3458 * pairs.h (SCM_NEWCELL): New debugging version added.
3459 * gc.h (scm_debug_newcell): Added extern declaration, used by
3460 debugging version of SCM_NEWCELL.
3462 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3464 On some systems <libc.h> conflicts with <unistd.h>, and should not
3465 be #included at all.
3466 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
3467 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
3468 * configure.in: Call it.
3469 * posix.c, filesys.c: Use its results to decide whether or not to
3471 * configure, scmconfig.h.in: Rebuilt with autoconf and
3474 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
3476 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
3477 pointer to the stdio stream before calling scm_setbuf0, so the
3478 latter will be able to retrieve it. I'm surprised this didn't
3479 segfault earlier. (Thanks to Christopher Lee.)
3481 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3483 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
3486 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3488 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
3489 number of stack narrowing specifier pairs. The first specifier in
3490 a pair controls inner border, the second the outer border. A
3491 number means cut that number of frames, a procedure object means
3492 cut until that object is found in operator position in a frame.
3494 * root.c (cwdr): Bugfix.
3496 * read.c: Recording of positions disabled by default.
3498 * procs.c (scm_closure_p): New function.
3500 * posix.c (scm_tmpnam): New function.
3502 * load.c: Added #include "throw.h".
3503 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
3506 * load.c, load.h (scm_read_and_eval_x): New function.
3508 * eval.c: Renamed debug option "deval" to "debug".
3510 (scm_eval_x): `eval!' is no longer accessible from the scheme
3511 level. Motivation: We can't allow operations which introduce
3512 glocs into the scheme level. Guile's type system can't handle
3513 these as data. Use `eval' or `read-and-eval!' as replacement.
3515 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
3516 SCM_CONSP since this is a macro!; Set vframe.prev to
3517 scm_last_debug_frame instead of 0. In this way we can look
3518 "above" the virtual start stack frame if we wish.
3519 (scm_debug_hang): New function: Useful for debugging Guile in
3520 certain tricky situations. Will probably be removed later...
3522 * debug.h: Changed semantics of debug option "backtrace". This
3523 option now only indicates whether we want automatic backtrace at
3526 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3528 * ports.c: #include "filesys.h"
3529 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
3531 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
3532 Motivation: This is system specific code which is related to file
3533 I/O. It also may use select. Added code by Gary Houston to
3534 detect presence of character in stdio buffers.
3536 * libguile.h: #include "libguile/libpath.h"
3538 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
3539 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
3540 SCM_SITE_DIR; Install libpath.h among the other include files.
3542 * load.c, load.h (scm_sys_package_data_dir): New function.
3544 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3546 * stacks.h: Bugfix: Don't use tail-array length field as stack
3547 length field! This screwed GC.
3549 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3551 * _scm.h: Added #ifndef around definition of macros min and max.
3553 * __scm.h: Added hooks for threads to plugin to in ints protection
3554 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
3555 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
3556 the main code in these macros duplicated and spread over multiple
3557 files. Renamed SCM_THREADS_SWITCHING_CODE ->
3558 SCM_THREAD_SWITCHING_CODE.
3560 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
3562 * snarf.h: New file.
3563 * guile-snarf.sh: New file.
3564 * Makefile.in (inner_h_files): Added snarf.h
3565 (ancillary, install, uninstall, distclean): Added actions for
3567 (.c.x): Use guile-snarf.
3568 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
3569 (gen_c_files): Note that these depend on guile-snarf.
3570 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
3571 now in "snarf.h". Added #include "snarf.h" to get them.
3572 * libguile.h: Added #include "snarf.h".
3573 (Patches applied and tweaked by Jim Blandy.)
3575 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
3577 * socket.c: Use K&R style declaration for 'close'; the GNU coding
3578 standards suggest against providing prototypes for system
3579 functions. Thanks to Greg Troxel.
3581 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3583 * strports.c (scm_eval_0str): New function.
3584 #include "read.h", to get prototype for scm_read.
3585 * Makefile.in (strports.o): Update dependencies.
3586 * strports.h: New prototype.
3588 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
3589 scheme name from "int?" to "integer?". It seems to do the job.
3590 * numbers.h: Rename prototype too.
3591 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
3594 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
3595 scm_num_eq_p): Rename these according to R4RS conventions: call
3596 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
3597 to making libguile R4RS compliant without ice-9...
3599 * load.c (scm_sys_search_load_path): Search for files under all
3600 extensions listed in the %load-extensions variable. If FILENAME
3601 is absolute, return it unchanged, without searching the load path.
3602 (scm_loc_load_extensions): New variable, pointing to
3603 %load-extensions' value cell.
3604 (scm_init_load): Initialize it, and the value it points to.
3605 (scm_primitive_load_path): Improve error reporting.
3607 * load.c (scm_loc_load_hook): New variable, pointing to value cell
3608 of new Scheme variable %load-hook.
3609 (scm_primitive_load): Apply %load-hook to filename.
3611 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
3613 * configure.in: add tests for figuring out whether buffered data
3614 is available in a FILE structure, which is needed by char-ready.
3616 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
3619 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
3620 exceptions using misc_error instead of syserror. It seems a bit
3621 odd to throw an exception if a string can't be found in the
3622 environment, but it's consistent with open-file, stat etc.
3623 (simpos.h): remove sys_ from getenv.
3625 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
3626 occurs, throw an error instead of returning errno. Return value
3628 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
3630 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
3632 * filesys.c (scm_stat2scm): derive file type and permissions from
3633 the stat mode and append them to the returned vector.
3634 There isn't much overhead in doing this and it avoids the need to
3635 work with S_IRUSR et al. in Scheme.
3636 Define symbols scm_sym_regular etc.
3637 (scm_init_filesys): don't intern S_IRUSR etc.
3639 * load.c: change s_try_load and s_try_load_path to s_primitive_load
3640 and s_primitive_load_path.
3642 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
3644 * error.h: don't declare error symbols. prototype for scm_misc_error.
3646 * stackchk.c (scm_stack_overflow_key): defined here instead of in
3649 * error.c: use SCM_SYMBOL to set up error keys.
3650 scm_misc_error: new procedure.
3652 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3654 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
3655 between `#!' and `!#' is ignored.
3656 (skip_scsh_block_comment): New function.
3658 * feature.c (scm_set_program_arguments): New argument, FIRST.
3659 * feature.h: Update prototype.
3660 * init.c (scm_boot_guile_1): Pass new argument to
3661 scm_set_program_arguments.
3663 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3665 * init.c (scm_start_stack): Don't initialize scm_progargs here.
3666 (scm_boot_guile): Call scm_set_program_arguments here, later than
3667 the old initialization.
3669 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
3670 initialization procedure.
3671 - Delete in, out, err arguments; there are other perfectly good
3672 ways to override these when desired.
3673 - Delete result argument; this function shouldn't ever return.
3674 - Rename init_func argument to main_func, for less confusion.
3675 - Delete boot_cmd argument; main_func is more general.
3676 -Add 'closure' argument, to help people pass data to main_func
3677 without resorting to global variables.
3678 - Abort if reentered; don't bother returning an error code.
3679 - Call scm_init_standard_ports to set up the default/current
3680 standard ports; no need to pass them to scm_start_stack.
3681 - Remove code to evaluate the boot_cmd, and start the repl; let
3682 the user do something like that in main_func if they want.
3683 - Remove code to package up a return value; main_func can do any
3685 - Call exit (0), instead of returning.
3686 (scm_start_stack): Don't initialize the I/O ports here; that's
3687 weird. Delete in, out, err arguments. Move guts to
3688 scm_init_standard_ports, scm_stdio_to_port.
3689 (scm_init_standard_ports): New function, to set up current and
3690 default standard ports.
3691 (scm_start_stack, scm_restart_stack): Make these static.
3692 * init.h (scm_boot_guile): Adjust declaration.
3693 (scm_start_stack, scm_restart_stack): Remove externally
3694 visible declarations for these.
3695 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
3697 * fports.c (scm_stdio_to_port): New function. Its guts used to be
3698 written out several times in scm_start_stack.
3699 * fports.h: New declaration for the above.
3701 * feature.c (scm_set_program_arguments): New function.
3702 * feature.h: New declaration for the above.
3704 * ports.c: Formatting tweak.
3706 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
3708 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
3709 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
3710 for obtaining the address of a car or cdr field. Motivation:
3711 &SCM_CXR make assumptions about the internal structure of the
3714 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
3715 Motivation: see SCM_CXRLOC.
3717 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
3718 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
3719 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
3720 Motivation: Safer use. Some other macros are defined in terms of
3721 these operations. If these are defined using the SCM_SETCXR
3722 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
3723 to inefficiency and an <e1> with side-effects could potentially
3724 break. Also, these particular operations are heavily utilized in
3725 the garbage collector. In unoptimized code there will be a
3728 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
3729 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
3730 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
3731 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
3732 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
3733 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
3734 vports.c: Cleaned up use of pairs: Don't make any special
3735 assumptions about the internal structure of selectors and
3736 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
3737 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
3738 (Among other things, this change makes it easier to build Guile
3739 with certain compilers which have problems with casted lvalues.)
3741 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3743 * stacks.c: Improve selection of relevant stack frames when making
3744 a stack object. Introduce one level of indirection in the stack
3745 object to make it possible to "narrow" to a certain region of the
3746 stack. This facilitates making use of more clever algorithms (not
3747 implemented) for selecting relevant frames and gives a cleaner
3748 design since selection of frames can be done independently of
3749 extraction of frames from the real stack.
3750 (scm_stack_id): Also take #t as argument which means look at
3753 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
3754 Turn n_tail into an integer directly representing current number
3755 of frames in stack. Add field tail.
3757 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
3759 * debug.c (scm_make_memoized): Made it available at scheme level.
3760 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
3761 SCM_NIMP before applying heavier predicates in argument checking.
3762 (scm_local_eval): Also take memoized object as argument.
3764 * backtrace.c (scm_display_error): Just a safety measure: Stacks
3765 aren't created with zero length, but should such a strange
3766 creature suddenly turn up...
3768 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
3770 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
3771 `del', for the sake of C++ compilers. (Patch applied by JimB.)
3773 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
3775 * variable.c (scm_make_variable): Make the name hint optional, as
3777 (anonymous_variable_sym): Renamed from variable_sym. All uses
3780 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
3781 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
3782 of scm_primitive_load_path was also changed to
3783 "primitive-load-path", from "%try-load-path". Callers changed.
3784 We'd like to respect the convention that a function named
3785 "try-mumble" should behave just like the function called "mumble",
3786 but return #f instead of signalling some error.
3787 * load.h: Rename prototypes.
3789 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3791 * print.c (make_print_state, grow_print_state), print.h: Modified
3792 the print state representation: Don't use a tail array for
3793 recording of circular references. Resizing of the print state
3794 structure invalidates the print state pointer. To avoid passing
3795 around an indirect print state reference to all printing
3796 functions, we instead let the print state reference a resizable
3799 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
3801 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
3802 Don't crash when passed an improper list terminated by a
3803 non-immediate value.
3805 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
3807 Allocate data for structures on an eight-byte boundary, as
3808 required by the tagging system.
3809 * struct.c (alloc_struct): New function.
3810 (scm_make_struct, scm_make_vtable_vtable): Call it.
3811 * struct.h (scm_struct_n_extra_words): Bump to 3.
3812 (scm_struct_i_ptr): New "field".
3813 * gc.c (scm_gc_sweep): When we need to free the data, use the
3814 information stored by alloc_struct to find the beginning of the
3815 block allocated to the structure, so we can free it.
3817 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3819 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
3822 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
3823 (scm_debug_info): New member: id.
3825 * stacks.c: Stacks are now represented as structs; Stacks have an
3826 id given to them by `start-stack'.
3827 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
3829 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
3830 Changed stack representation.
3832 * debug.c (scm_procedure_name): Try procedure property `name' for
3833 compiled closures aswell.
3835 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
3837 * eval.c: scm_i_name moved to gsubr.c
3838 (scm_m_define): Record names of all kinds of procedure
3839 objects. (Earlier, only closures were recorded.)
3841 * procprop.h: Added declaration of scm_i_name.
3843 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
3844 (scm_make_gsubr): Record names of compiled closures.
3846 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3848 * debug.c, debug.h: Removed obsolete code.
3850 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
3851 stacks.c: Renamed regs --> scm_contregs.
3853 * print.c (scm_free_print_state): Cleanup print state before
3854 returning it to pool. It is better to do it here than in
3855 scm_prin1 since scm_prin1 is called often.
3857 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
3858 s_set_source_property_x): Check that first argument is a pair or a
3861 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
3862 scm_i_line, scm_i_column and scm_i_breakpoint global.
3864 * init.c: Added #include "backtrace.h" and #include "stacks.h".
3865 (scm_boot_guile_1): Added calls to scm_init_backtrace and
3868 * debug.h: Added debug object smob declaration and macro
3871 * configure.in: Build with backtrace.o and stacks.o if debug
3874 * Makefile.in: Added entries for new files: backtrace.c,
3875 backtrace.h, stacks.c and stacks.h.
3877 * symbols.c (scm_sym2ovcell): Fixed documentation.
3879 * _scm.h (min, max): Added.
3881 * async.c: Moved `min' macro to _scm.h.
3883 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
3884 SCM_BACKTRACE_INDENT.
3886 * eval.c: Added new debug options `maxdepth' and `indent'.
3888 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
3890 * print.h: Added selector SCM_PRINT_STATE.
3892 * print.c: New functions: scm_make_print_state,
3893 scm_free_print_state.
3895 * print.h: Added declarations for scm_make_print_state,
3896 scm_free_print_state.
3898 * debug.c (scm_m_start_stack): New acro.
3900 * debug.h: Small cleanup.
3902 * init.c (scm_boot_guile_1): Moved scm_init_debug below

3927 declare functions with prototypes. (Patch thanks to Marius
3930 More prototype-related changes from Marius Vollmer:
3931 * gdb_interface.h: Wrapped header file in #ifdef/#endif
3932 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
3933 * ports.h (ptobfuns): Added prototypes. This means some casting in
3935 * fports.c: Added casts for initializations, since the functions
3936 are defined to take FILE * as their stream argument, not SCM.
3937 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
3938 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
3939 to `char *str_data' to conform to prototype.
3941 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
3943 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
3945 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
3947 * stime.c, stime.h: use SCM_P method.
3949 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
3951 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
3952 be given at least two arguments. Insist that lst's last element
3953 be a list, but don't make any requirements of its predecessors.
3955 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
3957 * eval.c (scm_nconc2last): Revert last change; there seems to be
3958 other stuff going on here.
3960 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
3962 * eval.c (scm_nconc2last): Make sure that each element of lst
3963 (which is a list of argument lists, except for the tail) is a
3964 proper list, i.e., finite and terminated by '().
3966 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
3968 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
3971 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
3972 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
3975 * vectors.c (scm_make_vector): Fill vectors with the undefined
3976 value, to help make Guile Scheme code more portable to other
3979 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
3980 * symbols.h, tags.h: Doc fixes.
3982 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
3984 * async.c (scm_take_signal): Doc fixes.
3986 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
3988 * numbers.c (scm_divbigint): When the remainder is zero, we don't
3989 want to subtract it from the modulus; we just want to leave it
3992 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
3994 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
3997 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
3999 * throw.c (scm_catch_apply): Finished implementation of
4002 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4004 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4006 (scm_init_filesys): set "i/o-extensions" feature.
4009 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4011 * Makefile.in (root.o): Correct dependencies.
4013 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4015 * Makefile.in: Added dependency entry for root.o.
4017 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4018 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4020 * init.c (scm_start_stack): Set initial root continuation number
4023 * procs.c: New function: scm_thunk_p.
4025 * procs.h: Added declarations of scm_thunk_p.
4027 * root.c: Renamed `call-with-new-root' -->
4028 `call-with-dynamic-root'.
4029 (cwdr): Removed allocation of new root state. This should be done
4030 separately by use of scm_make_root.
4031 (scm_apply_with_dynamic_root): New function: Does what it
4032 sounds like. Needed when spawning threads.
4034 * root.h: Added member last_debug_frame to root state.
4035 Added #include "libguile/debug.h"
4037 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4038 arguments. The motivation is that code in root.c needs catch
4039 functionality, and we want to avoid code duplication.
4040 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4041 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4042 handlers that run without popping the stack into the dynwind
4045 * throw.h: Added prototypes for scm_catch_apply and
4048 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4050 * root.h (scm_root, scm_set_root): Decouple thread support details
4051 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4052 SCM_SET_THREAD_LOCAL_DATA.
4054 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4055 and tortoise scanning loop.
4057 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4059 * Makefile.in: Rebuild dependencies.
4061 * libguile.h: #include "libguile/print.h" before "smob.h", since
4062 the latter uses the print_state structure.
4064 * throw.c (scm_ithrow): Use the correct variable when checking to
4065 see if a given element of scm_dynwinds is a valid catch.
4067 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4068 structure, abort; don't just silently ignore the garbage.
4070 * _scm.h: #include "print.h" here, since it seems to be used just
4072 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4073 strports.c, unif.h: Don't #include "print.h".
4075 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4077 * feature.h (scm_loc_features): Removed external declaration.
4078 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4080 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4082 * feature.c (scm_init_feature): Added threads feature (needs to be
4083 initialized here, since features doesn't exist when
4084 scm_init_threads is called).
4086 * libguile.h: Added #include "libguile/../threads/threads.h".
4087 (This is a kludge to get thread support working. This should be
4090 * configure.in, acconfig.h: Added flags for thread support.
4092 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4095 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4096 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4099 * _scm.h: Added conditional #include "threads.h"
4101 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4102 SCM_THREADS_SWITCHING_CODE.
4104 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4105 allocate the basic dynamic root object.
4106 (scm_boot_guile): Added call to scm_init_root.
4108 * root.c, root.h: Added root smob.
4109 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4110 functions: Implements dynamic roots mostly according to spec in
4111 SCM manual. Main difference is that the second argument is a
4112 throw handler rather than an error "thunk".
4114 * root.h: Added declaration of scm_init_root.
4116 * root.c: Added #include "genio.h", #include "smob.h", #include
4117 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4119 (scm_init_root): Added #include "root.x".
4121 * throw.c: Added #include "stackchk.h"
4122 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4123 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4124 can be used in scm_call_with_new_root; Added reenabling of stack
4125 checking when catching a throw.
4127 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4129 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4131 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4132 element is not found, as per R4RS.
4134 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4136 * list.c: Doc fixes throughout.
4138 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4140 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4141 declare the char * to be const. Avoids a warning in rgx.c.
4143 * ports.h: spelling fix.
4145 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4148 * load.c (scm_sys_try_load_path): throw an error if file not found
4149 (like it says it in NEWS).
4151 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4153 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4154 PROPS slot to '(), not #f; it's an empty alist.
4156 * throw.h, throw.c: Use SCM_P instead of #if hair.
4158 Remove special support for uncaught throws; see throw.c for
4160 * throw.c (uncaught_throw): New function.
4161 (scm_ithrow): Call uncaught_throw if we don't find a throw
4162 target; don't mess with scm_bad_throw_vcell.
4163 (scm_bad_throw_vcell): Variable deleted.
4164 (scm_init_throw): Don't initialize it.
4166 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4169 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4171 * numbers.c (scm_istr2int): If the number is short (as most
4172 numbers are), just call scm_small_istr2int to deal with it.
4173 (scm_small_istr2int): New function, created by un-#ifdefing the
4174 non-bignum version of scm_istr2int and renaming it.
4176 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4178 * load.c (scm_sys_try_load): don't check whether value returned
4179 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4180 Change the Scheme name from %try-load to primitive-load.
4182 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4183 Can avoid passing a message, allowing it to be derived in the
4184 error handler (e.g., if we want to throw to the key both from
4187 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4189 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4190 references now have a new appearance which is more compact and
4191 also gives a clue about what the target of the reference is.
4192 By setting parameters in the print state, more fancy printing can
4193 be achieved. This is used by the (not yet commited) backtrace
4196 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4198 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4201 * print.c: Added #include "struct.h". Removed function
4204 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4205 scm_iprin1. Removed prototype for scm_prlist.
4207 * arbiters.c (prinarb),
4208 async.c (print_async),
4209 debug.c (prindebugobj, prinmemoized),
4210 eval.c (prinprom, prinmacro),
4211 filesys.c (scm_fd_print, scm_dir_print),
4213 mallocs.c (prinmalloc),
4214 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4215 smob.h (scm_smobfuns),
4216 srcprop.c (prinsrcprops),
4218 unif.c, unif.h (scm_raprin1, rapr1),
4219 variable.c (prin_var): Changed argument `int writing' to
4220 `scm_print_state *pstate'.
4222 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4223 that it will be called before scm_init_print.
4225 * print.c (scm_prin1): Print states are now allocated when calling
4226 scm_prin1 and then passed around to all printing functions as an
4227 argument. A cache `print_state_pool' enables reuse of print
4229 (scm_make_print_state): New function.
4230 (scm_iprin1): Adaption to print states.
4231 (scm_iprlist): An initial "hare and tortoise" scan brings down
4232 time complexity to O (depth * N). (Better time complexity will be
4233 achieved when the printing code is completely rewritten.)
4235 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4237 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4238 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4239 it gets done whether or not the cache variable has a value.
4241 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4243 Distinguish #f and ().
4244 * __scm.h: #undef SICP.
4245 * pairs.h (SCM_EOL): Delete this definition, equating it with
4247 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4248 the value it used to have. Doc fixes, too.
4250 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4252 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4253 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4254 Lord's implementation of structs, allowing for tail arrays as
4255 described in the manual. Also fixed some bugs. (Both the interface
4256 and the implementation should be improved.)
4258 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4260 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4261 People who whish to see the source can do `(print-enable 'source)'.
4262 Removed #ifdef DEBUG_EXTENSIONS.
4264 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4266 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4267 integer (assuming for now accepting an integer is a good thing).
4269 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4270 %S will be used instead for write'ing arguments.
4272 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4273 asserts. fix a few other asserts.
4274 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4275 scm_uniform_vector_ref, scm_array_set_x,
4276 scm_dimensions_to_unform_array): change args in
4277 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4278 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4279 scm_substring_fill_x): likewise.
4280 gsubr.c (scm_gsubr_apply): likewise.
4281 eval.c (SCM_APPLY): likewise.
4283 * eval.c (4 places): replace scm_everr with lgh_error or
4286 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4287 scm_memory_error): new procedures.
4288 scm_everr: deleted. can use scm_wta, dropping first two args.
4289 scm_error: convert NULL subr to SCM_BOOL_F.
4291 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4294 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4297 * error.c, error.h: new error keys: scm_arg_type_key,
4298 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4300 scm_wta: reimplement using lgh_error instead of scm_everr.
4302 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4304 * gdbint.c: scm_lread now has one more argument.
4306 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4307 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4308 loading source from non-file ports, which, e. g., happens when
4309 using the Emacs interface).
4311 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4314 * read.c: Added code for recording of positions of source code
4315 expressions; New functions: recsexpr, scm_lreadrecparen;
4316 _scm_make_srcprops --> scm_make_srcprops
4317 (scm_flush_ws): Removed updating of positions counters. This work
4318 is already done by scm_gen_getc
4320 * read.h: Added prototype for scm_lreadrecparen
4322 * print.c: Added #include "alist.h"
4324 * eval.c: Added #include "hash.h"
4326 * eq.c: Added #include "ramap.h"
4328 * options.c: Documentation fixes.
4330 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
4331 (scm_init_srcprop): Adjusted size of initial source-whash. Name
4332 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
4333 --> scm_make_srcprops
4335 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
4336 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
4337 function calls in the definition of the whash access macros.
4339 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
4341 * init.c (scm_boot_guile): Add level of indirection to
4342 scm_boot_guile_1() to ensure that stack base pointer is properly
4343 initialized. There was no guarantee that variable i was the
4344 highest/lowest variable on stack (i.e. the call frame of
4345 scm_boot_guile was not completely protected from gc).
4347 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
4349 * ports.h (scm_port_table): put back file_name, it will be used to
4350 support debugging. Undo related changes in fports.c, ioext.c,
4353 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4355 * ports.h (scm_port_table): remove file_name member for now, it seems
4357 * fports.c (scm_open_file): don't set file_name in PTAB.
4358 (prinfport): don't use file_name in PTAB.
4359 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
4360 * ports.c (scm_add_to_port_table): don't intialize file_name.
4361 (scm_port_file_name): remove for now.
4362 * gc.c (scm_gc_mark): don't mark PTAB file_name.
4364 * fports.h (scm_mkfile): prototype deleted.
4365 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
4367 * debug.c, unif.c: use scm_out_of_range instead of
4368 wta for range errors (ASSERT still needs work).
4370 * error.c, error.h (scm_out_of_range): new procedure.
4372 * error.c, error.h (scm_out_of_range_key): new key.
4374 * posix.c (scm_sync): #else was missing.
4376 * error.c, error.h: append _key to names scm_num_overflow and
4379 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
4380 of consing an empty list.
4381 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
4382 of macros, saves code and string space.
4383 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
4384 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
4385 lower case. Rename scm_syserror_m to scm_syserror_msg.
4386 error.h: prototypes for new procedures.
4388 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
4390 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
4392 * error.c, error.h: setup scm_num_overflow key.
4394 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
4395 Remove definition of SCM_OVSCM_FLOW.
4397 * fports.c (scm_open_file): use SCM_SYSERROR_M.
4399 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
4400 explicit message and args.
4402 * error.c, error.h, __scm.h: change system_error_sym to
4405 * error.c (system_error_sym): remove leading %% from the Scheme name
4408 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
4410 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4412 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
4413 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
4414 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
4415 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
4416 renamed. (These were introduced by unsupervised name
4419 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4421 * print.c: Added code for detection of circular references during
4422 printing. (init_ref_stack, grow_ref_stack): New functions. Added
4423 a hook for printing of closures (accessible via print options).
4424 This leads to a split of calls to scm_iprin1 into two classes:
4425 elementary print operations (e. g. the code which prints a smob)
4426 still use scm_iprin1 while top level calls (like scm_display) use
4427 scm_prin1. scm_prin1 begins by clearing the data structure used
4428 to record reference information.
4430 * print.h: Added declarations of scm_prin1 and scm_prlist.
4432 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
4434 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
4436 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
4438 * error.c (err_head): scm_iprin1 --> scm_prin1
4440 * debug.c: Adjusted header comment.
4444 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4446 * strerror.c: Doc fix.
4448 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4450 * gdbint.c (gdb_read): Now possible to run during GC.
4451 (unmark_port, remark_port): New functions.
4453 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
4455 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
4456 of allocating a new string object. Also, increase size by
4457 the factor 2 instead of 1.5.
4459 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
4461 * __scm.h (SCM_P): Corrected to run under traditional C.
4463 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
4466 * async.c: Calls to scm_sysintern corrected.
4468 * async.h (scm_async_clock): Redundant declaration removed.
4470 * continuations.c (scm_dynthrow): Redundant declaration removed.
4472 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
4473 Definition typos corrected.
4475 * debug.h: Missing declarations of functions in debug.c added
4478 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
4479 Missing declarations to functions in eval.c added.
4481 * filesys.c: Possibly uninitialized variable rv.
4483 * gc.h (scm_object_addr, scm_unhash_name): Missing
4484 declarations of functions defined in gc.c added.
4486 * genio.c: Possible typos str_data -> wstr_data. ???
4488 * genio.c: Possibly unintended shadowing of local variable
4489 `int c' (gotos out of scope of inner `c'). ???
4491 * init.c: Uninitialized `SCM last' may be used.
4493 * ioext.h: (scm_sys_isatty_p): Typo.
4495 * list.h (scm_list_head): Missing prototype for function in
4498 * numbers.c (scm_two_doubles): Changed from extern to static
4499 (is used only within numbers.c).
4501 * numbers.h: Repeated declarations removed.
4503 * ports.h (scm_close_all_ports_except): Declaration for the
4504 function defined in ports.c added.
4506 * posix.h: Missing declarations added.
4508 * procs.h (scm_make_subr_opt): Missing declaration added.
4510 * socket.h (scm_sys_gethost): Missing declaration added.
4512 * socket.h: Redundant declarations removed (they are in fdsocket.h).
4514 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
4515 Missing declarations added.
4517 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
4519 * struct.c: Uninitialized variable `SCM answer' may be used.
4521 * unif.c (l2ra): Declaration prototype.
4523 * unif.c (scm_array_equal_p): Dummy definition removed (it is
4524 defined in ramap.c).
4526 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
4527 Redundant declarations removed (they are in ramap.h).
4529 * variable.h (scm_make_udvariable,
4530 scm_make_undefined_variable): Declaration corrected to
4531 correspond variable.c.
4533 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
4534 Missing declarations added.
4536 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
4538 * Makefile.in (distclean): Don't forget to delete fd.h.
4540 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4542 * fd.h.in, tags.h: Trivial cleanups.
4544 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
4545 marksweep.h just declared functions from gc.c.
4546 * gc.h, libguile.h: Don't #include "marksweep.h".
4547 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4548 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
4549 dependencies updated.
4551 * libguile.h: Don't #include "files.h"; it's been deleted.
4553 * files.c (scm_sys_delete_file): Moved to filesys.c.
4554 File is now empty; deleted.
4556 * filesys.c: scm_sys_delete_file is now here. Remove
4557 #if's; they seem to rely on remnants of an old portability
4558 regimen. If the problems come up again, solve them properly,
4559 using autoconf. Specifically: Don't test M_SYSV, and #define
4560 remove to be unlink if it's #defined; don't use remove just
4561 because HAVE_STDC_HEADERS is #defined.
4562 * filesys.h: Add declarations for scm_sys_delete_file.
4563 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4564 files.o, files.h, files.c, and files.x.
4565 * init.c: Don't #include "files.h", and don't call scm_init_files.
4567 Use SCM_P instead of PROTO; the latter intrudes on the user's
4569 * params.h: Deleted; definition of SCM_P moved to...
4570 * __scm.h: ... here, where it replaces PROTO macro.
4571 * libguile.h, smob.h: Don't #include "params.h".
4572 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
4573 smob.h: Fix prototypes accordingly.
4574 * Makefile.in: Update dependencies.
4575 (inner_h_files): Remove params.h.
4577 * gc.c: #include "gc.h"; every module should include its header,
4578 to let the compiler cross-check the declarations against the
4581 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
4582 simpos.h: #include "libguile/__scm.h".
4584 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
4586 * init.c: Don't forget to #include smob.h and init.h.
4587 * Makefile.in: Dependencies updated.
4589 * smob.h: Use PROTO instead of #if __STDC__.
4591 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
4593 * __scm.h: Doc fixes.
4595 * __scm.h, libguile.h: Use "quotes" in the #includes, not
4596 <angles>; this allows `make depends' to work properly.
4598 * libguile.h: #include smob.h and pairs.h before the others; they
4599 define typedefs used by other headers.
4601 C files should #include only the header files they need, not
4602 libguile.h (which #includes all the header files); the pointless
4603 recompilation was wasting my time.
4604 * Makefile.in (all .o dependency lists): Regenerated.
4605 * libguile.h: Don't try to get a definition for size_t here...
4606 * __scm.h: Do it here.
4607 * _scm.h: Since this is the internal libguile header, put things
4608 here that all (or a majority) of the libguile files will want.
4609 Don't #include <libguile.h> here; that generates dependencies on
4610 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
4611 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
4612 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

4709 * weaks.c: Get "weaks.h".
4711 * stackchk.h: #include "libguile/debug.h",
4713 * print.h, read.h: #include "options.h", since everyone who uses
4714 either of these files will need that.
4716 * smob.h: #include "ports.h", "genio.h", and "print.h", since
4717 anyone who uses this file will need them to define the smob
4718 printing functions. Also, get markers.h, since people will need
4719 to #define the mark functions.
4721 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
4722 * ports.h: ... to here.
4724 * ports.h (scm_port_table_size): Explicitly give type as 'int';
4725 don't rely on archaic C default type rules.
4727 * fports.h: #include "libguile/ports.h", since you need that in
4728 order to parse this.
4730 * genio.h: #include "libguile/print.h", because you need that to
4731 parse this; don't bother #including "ports.h", since print.h gets
4734 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
4736 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
4737 this; it's now a reference to an element of *scm_root.
4739 * debug.h: Don't #include "options.h"; the compiler won't be able
4740 to find that once the headers are installed; instead, #include
4741 "libguile/options.h".
4742 * gc.h: Same, with marksweep.h.
4743 * mbstrings.h: Same, with symbols.h.
4744 * scmhob.h: Same, with _scm.h.
4745 * smob.h: Same, with params.h.
4747 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
4748 C files; there's no need for this, and it forces recompilations
4751 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
4753 * error.c (scm_error): declare scm_error_callback.
4755 * error.h: prototype for scm_error_callback.
4757 * __scm.h: define lgh_error.
4758 (SCM_SYSERROR): redefine using lgh_error.
4760 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
4762 * error.c (scm_error): new procedure.
4764 * error.h: prototype for scm_error.
4766 * Makefile.in (install): install scmconfig.h from the current
4767 directory, not $(srcdir).
4769 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
4771 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,

4782 dependencies are within libguile properly.
4784 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
4786 * Makefile.in (.c.x): Simplify; there's no need to run this rule
4787 when scmconfig.h doesn't exist.
4789 * load.c (scm_sys_try_load): Correct spelling.
4791 * feature.c (scm_loc_features): Make this static.
4793 * Makefile.in (libpath.h): Omit trailing slash from path. We
4794 shouldn't require it of users, so why put it here?
4796 Move code to initialize and search %load-path from ice-9 to C
4797 code, so we can use the load-path to find the ice-9 boot code;
4798 this makes it easier to run Guile without installing it. See
4799 corresponding changes in guile/Makefile.in.
4800 * feature.c: Move stuff concerned with the load path to load.c.
4801 (scm_compiled_library_path): Deleted.
4802 Don't #include libpath.h here.
4803 * feature.h: Don't mention scm_compiled_library_path.
4804 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
4805 <sys/stat.h>, and <unistd.h> (if present).
4806 (R_OK): #define if the system hasn't deigned to.
4807 (scm_loc_load_path): New variable.
4808 (scm_init_load_path, scm_sys_search_load_path,
4809 scm_sys_try_load_path): New functions.
4810 (scm_init_load): Initialize scm_loc_load_path to point to the
4811 value cell of the Scheme %load-path variable.
4812 * load.h: Add declarations for scm_sys_search_load_path,
4813 scm_sys_try_load_path.
4814 * init.c: Call scm_init_load_path.
4815 * Makefile.in (feature.o, load.o): Dependencies updated.
4817 * load.c, load.h: Rewrite using PROTO macro.
4819 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4821 * gc.c (scm_cellp): New function: C predicate to determine if an
4822 SCM value can be regarded as a pointer to a cell on the heap.
4824 * gc.h: Added declaration of scm_cellp.
4826 * gdb_interface.h: New file: The GDB interface header from the GDB
4829 * gdbint.c: New file: GDB interface.
4831 * gdbint.h: New file: GDB interface.
4833 * libguile.h: Added #include <libguile/gdbint.h>.
4835 * init.c (scm_boot_guile): Added scm_init_gdbint.
4837 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
4838 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
4839 found if object files and source are kept separate).
4841 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
4843 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
4845 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
4847 * configure.in: Don't substitute the values of TCL_SRC_DIR and
4848 TK_SRC_DIR; they're not relevant any more.
4850 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
4851 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
4853 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
4855 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
4856 search path, so we can find the <libguile/MUMBLE.h> headers.
4858 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
4860 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
4861 implicit in the .c.o rule.
4862 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
4865 Put the library path in a header file, instead of passing it on
4866 the command line in every compilation.
4867 * Makefile.in (libpath.h): New target.
4868 (feature.o): Depend on libpath.h.
4869 (clean): Delete libpath.h.
4870 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
4871 * feature.c: ... #include "libpath.h" here.
4872 * .cvsignore: Ignore libpath.h.
4874 Don't install the unwashed masses of Guile header files in the
4875 main #include path; put most of them in a subdirectory called
4876 'libguile'. This avoids naming conflicts between Guile header
4877 files and system header files (of which there were a few).
4878 * Makefile.in (pkgincludedir): Deleted.
4879 (innerincludedir): New variable; this and $(includedir) are enough.
4880 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
4881 (installed_h_files): Divide this up. Now this variable lists
4882 those header files which should go into $(includedir) (i.e. appear
4883 directly in the #include path), and ...
4884 (inner_h_files): ... this new variable says which files appear in
4885 a subdirectory, and are referred to as <libguile/mumble.h>.
4886 (h_files): List them both.
4887 (install): Create innerincludedir, not pkgincludedir. Put
4888 the installed_h_files and inner_h_files in their proper places.
4889 (uninstall): Corresponding changes.
4890 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
4891 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
4892 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
4893 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
4894 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
4895 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
4896 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
4897 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
4898 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
4899 vports.h, weaks.h: Find __scm.h in its new location.
4900 * __scm.h: Find scmconfig.h and tags.h in their new locations
4901 (they're both "inner" files).
4903 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
4905 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
4907 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4909 * posix.c: Doc fixes.
4911 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
4913 * socket.c: Don't include a prototype for inet_aton; just use a
4914 K&R style declaration, to avoid warnings but minimize the chance
4915 of conflicts with the system.
4917 On NextStep, <utime.h> doesn't define struct utime, unless we
4918 #define _POSIX_SOURCE before #including it.
4919 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
4920 * acconfig.h: New comment text for above CPP symbol.
4921 * configure.in: Call it.
4922 * posix.c: #define _POSIX_SOURCE if it seems necessary.
4924 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
4926 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
4927 testing for __EMX__.
4929 * posix.c: #include <libc.h>, if it exists.
4931 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
4932 don't even know if the latter exists.
4934 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
4935 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
4936 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
4938 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
4940 (scm_init_posix): Use them when initializing the Scheme constants
4943 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4945 * Makefile.in (libdir, includedir, bindir): Use the
4946 autoconf-supplied values, instead of deriving them ourselves.
4947 (pkgincludedir, datadir, pkgdatadir): New variables.
4948 (install, uninstall): Put the header files in a special
4949 subdirectory, not in the main search path.
4951 * Makefile.in (ALL_CFLAGS): Provide the proper value for
4952 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
4954 * Makefile.in (IMPLPATH): Deleted; never used.
4956 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
4957 on the Tcl/Tk source any more.
4958 (INCLUDE_CFLAGS): Remove references to the above.
4960 * Makefile.in (version.o): Corrected dependencies.
4962 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
4964 * libguile.h: #include "version.h"
4966 * init.c (scm_boot_guile): Call scm_init_version.
4967 * gscm.c (gscm_run_scm): Call scm_init_version.
4969 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
4970 GUILE_VERSION): AC_DEFINE these.
4971 (acconfig.h): #undef the above symbols.
4973 * Makefile.in (libobjs): Add version.o.
4974 (installed_h_files): Add version.h.
4975 (c_files): Add version.c.
4976 (gen_c_files): Add version.x.
4977 (version.o): New rule.
4978 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
4979 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
4980 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
4981 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
4982 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
4983 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
4984 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
4985 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
4986 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
4987 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
4988 weaks.o): Add version.h to dependency lists.
4989 (markers.o): Remove duplicate rule.
4991 * version.h: New file.
4993 * version.c: New file.
4995 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4997 * symbols.c (scm_strhash): scm_downcase is now a function, not an
4998 array; use it appropriately. Since GCC is quite happy to
4999 subscript functions, it never warned us about this; we should use
5000 -Wpointer-arith in the future. I guess we never tested
5003 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5005 * socket.c: Doc and copyright fixes.
5007 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5009 * debug.c: Fixed and improved gdb support.
5011 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5013 * socket.c: Added declaration of inet_aton to avoid compiler
5014 warning. (Hope this solution is correct.)
5016 * stime.c: Added declaration of ftime. (This is missing in
5019 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5021 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5023 * Makefile.in (c_files): add strerror.c.
5025 * strerror.c: new file from Emacs' sysdep.c.
5026 maybe configure should also check for sys_errlist.
5028 * configure.in (AC_REPLACE_FUNCS): add strerror.
5030 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5032 * debug.c (scm_init_debug): Added initialization for
5033 scm_evaluator_traps.
5035 * debug.h, debug.c: Various name changes.
5036 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5037 "debug-options-interface". See commentary in options.c.
5039 * options.h, options.c: Options now have documentation strings.
5040 Also added a long explanatory commentary.
5042 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5045 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5046 last_debug_info_frame is now updated in all cases.
5048 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5051 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5053 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5054 Added option STACK_CHECKING.
5056 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5058 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5060 * __scm.h: Removed symbols for debugging support.
5062 * acconfig.h: Added symbols for debugging support.
5064 * configure.in: Added user option for debugging support.
5065 --enable-debug will include the debugging code into libguile.a.
5067 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5068 scm_relocate_chunk_to_heap.
5070 * debug.c: New file: low-level debugging support. It also
5071 includes support for debugging with gdb. (The extensions to gdb
5072 are written by Per Bothner at Cygnus.)
5074 * debug.h: New file: low-level debugging support.
5076 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5077 argument pairs. Extensive modifications to the debugging
5078 evaluator. Added "SECTION:" commentaries to clarify what happens
5079 when, during double compilation. Renamed EVALIMP --> EVALIM.
5080 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5081 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5082 the beginning of the file. New procedure: scm_unmemocopy.
5083 Added some global state variables needed by the debugging
5084 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5085 check_entry, check_apply, check_exit, debug_options and
5086 evaluator_traps. New acro: undefine.
5088 * eval.h: Renamed EVAL --> XEVAL.
5090 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5091 --> scm_make_weak_key_hash_table.
5093 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5094 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5096 * libguile.h: Conditionally include debug.h
5098 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5099 scm_object_properties shouldn't return handle. `handle' now gets
5100 initialized in scm_set_object_properties_x. scm_object_properties
5101 doesn't any longer create an entry in scm_object_whash.
5103 * options.c: New file: handling of run time options.
5105 * options.h: New file: handling of run time options.
5107 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5109 * print.c: New procedure: scm_print_options
5111 * print.h: Defines for print options.
5113 * read.c: New procedure: scm_read_options
5115 * read.h: Defines for reader options.
5117 * root.h: Added scm_source_whash among scm_sys_protects.
5119 * srcprop.c: New file: source properties.
5121 * srcprop.h: New file: source properties.
5123 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5124 (Bug found by A. Green.)
5126 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5128 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5130 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5132 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5134 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5135 and should be called by the final client.
5137 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5139 * gc.h: Use the PROTO macro when declaring functions.
5140 * gc.c: Use the PROTO macro when declaring static functions.
5141 Remove the CPP hair around function definitions.
5143 * gc.c (scm_init_storage): Initialize scm_asyncs.
5145 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5146 preprocessor symbol; "__scm.h" is where it might get #defined.
5147 * __scm.h: Similar: #include <scmconfig.h> before testing
5150 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5152 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5154 * init.c (scm_boot_guile): Add init_func argument; call
5155 (*init_func) instead of calling scm_appinit; it's ucky to
5156 hard-code names for the user's procedures.
5157 * init.h (scm_boot_guile): Adjust declaration.
5159 * __scm.h (PROTO): New macro, for declaring functions with
5162 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5163 eliminate all the __STDC__ conditionals.
5164 (scm_boot_guile): Add declaration.
5165 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5166 Remove __STDC__ conditionals around function definitions; the
5167 declarations in init.h will provide the same information, more
5170 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5171 complain about it in the error message; the error message is
5172 adequate without that note, and there's nothing the user can do
5175 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5177 * Makefile.in (ancillary): Drop def.sed.
5179 * posix.c (scm_init_posix): Use numeric values, rather than
5180 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5181 F_OK. The symbols aren't available on some systems, and I'm
5182 pretty sure their values are fixed by common widespread practice.
5183 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5185 More functions unavailable on some systems.
5186 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5187 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5189 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5190 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5191 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5192 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5193 stub that signals an error as the #else.
5195 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
5197 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
5199 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
5201 * unif.c: include ramap.h.
5203 * read.c (endif): case_insensative_p renamed case_insensitive_p.
5205 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
5207 * ports.c: include sys/ioctl.h.
5209 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
5211 * configure.in: check for sys/ioctl.h.
5213 * ports.c: include <malloc.h> not "malloc.h".
5215 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5217 * fports.c: remove ttyname and tmpnam declarations.
5219 * posix.c: fewer ttyname declarations.
5221 * fports.c: include <string.h> not "string.h".
5223 * init.c, ioext.c: include string.h and unistd.h.
5225 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5227 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
5228 genio.c, simpos.c, vports.c: include string.h.
5230 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
5232 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
5234 (scm_addr_buffer_size): change type from scm_sizet to int.
5235 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
5236 from scm_sizet to int.
5238 * error.c: include unistd.h.
5240 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
5243 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
5245 * __scm.hd, def.sed: deleted.
5247 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
5249 Changes for NeXT, suggested by Robert Brown.
5250 * configure.in: Call AC_TYPE_MODE_T.
5251 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
5252 NeXT. Put header file list in alphabetical order.
5253 * configure, scmconfig.h.in: Regenerated.
5254 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
5256 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
5259 * acconfig.h: New file, providing documentation for the CPP
5260 symbols defined in configure.in
5261 * acconfig-1.5.h: Removed; superceded by the above.
5263 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
5265 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
5267 * fports.c (scm_open_file): don't return #f, throw error.
5269 * ioext.c (fileno): renamed from %fileno.
5270 (soft-fileno): deleted.
5272 * ports.c (scm_port_revealed): don't need to check for -1 from
5274 (scm_set_port_revealed_x): return unspecified, not #f.
5276 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
5278 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
5280 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
5282 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.

5286 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5287 This is necessary on Ultrix, and doesn't hurt portability.

5290 (installed_h_files): Put in alphabetical order.
5291 Remove duplicate entries for markers.h and unif.h.

5293 (ancillary): Renamed from anillery; all uses changed. Remove
5294 PLUGIN; it's a directory, and needs special treatment in dist-dir.
5295 Remove all the ../doc/* files; doc/Makefile.in handles that.
5297 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5299 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5300 every if must have an else, or else the whole command has a
5301 non-zero exit code whenever the if's condition is false.

5368 matter so long as it is non-0 (got rid of "* 4").
5370 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
5372 * gscm.h: gscm_mkarray eliminated (presumably was not being used
5373 since its definition was bogus).
5375 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
5377 * mallocs.[ch]: back again (for rx at least).
5379 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
5381 * ports.c: removed functions relating to the mapping between ports
5382 and descriptors. (That stuff is unix-specific and should be collected

5390 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
5391 handled correctly (SCM_FREEP was applied to them) -- test for

5560 initialization to fix a race condition.
5562 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

5586 set the multi_byte flag correctly in symbols. This is wrong.
5587 intern_obbary_soft and msymbolize should take an extra parameter.

5589 The weird symbol syntax is also a bit bogus (emacs doesn't quite
