1 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3 * filesys.c (dirname, basename): New procedures.
5 * init.c (scm_boot_guile_1): Removed condition around
8 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
9 new data type (guards) for representation of C level guards and
10 data on the wind chain.
11 (scm_internal_dynamic_wind): New function.
13 * dynwind.h: Declare scm_internal_dynamic_wind.
15 * root.h (scm_root_state): Added scm_cur_loadp.
17 * root.c (mark_root): Added comment about cur_loadp.
19 * load.c: #include "dynwind.h";
20 (scm_primitive_load): Use scm_inner_dynamic_wind to update
23 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
25 * ports.c (current-load-port): New procedure.
27 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
29 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
32 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
33 to Julian Satchell and Roland Kaufmann.)
35 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.

38 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
40 * debug.h, debug.c (scm_start_stack): New function. Implements
41 the guts of old scm_m_start_stack.
43 * debug.c (scm_m_start_stack): Use scm_start_stack.
45 * init.c (scm_start_stack, scm_restart_stack): Renamed to
46 start_stack and restart_stack. (These have static scope.)
48 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
50 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
51 readline functions to come in release 2.3. (Thanks to Chet
53 (handle_errors): Use the above functions.
55 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
57 * readline.c: Improvements for readline support: Handle errors
58 better; Implement before-read-hook.
60 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
62 * init.c (scm_boot_guile_1), readline.c: Test for
63 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
64 assure that we have version >= 2.1.)
66 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
68 * readline.c (scm_add_history): Bugfix: Do strdup before giving
69 away the string to add_history.
70 (completion_function): Do completion for readline. (Thanks to
72 (scm_filename_completion_function): New procedure: Filename
74 (current_input_getc): New function. Use this one instead of
75 standard getc from readline.
77 * throw.c, throw.h (scm_handle_by_throw): New function: This
78 handler throws errors to next handler on the dynwind chain.
80 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
82 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
85 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
87 * procprop.c (scm_i_procedure_arity): New function. Returns arity
89 (scm_procedure_properties): Modified to return arity together with
91 (scm_procedure_property): Added the read-only property `arity'.
92 (scm_set_procedure_property_x): It is an error to set the `arity'
95 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
96 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
98 * procprop.h (scm_sym_arity): New symbol.
100 * objects.c (scm_set_object_procedure_x): New procedure: Use this
101 to set the dispatch procedure of an operator or entity object.
103 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
104 Made procedure slots read-only.
106 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
107 scm_tcs_cons_gloc case in zero args switch; Fixed args
108 construction for operators in scm_tcs_cons_gloc case in two args
111 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
113 * fluids.c: Removed use of assert.h (in order to avoid
116 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
118 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
120 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
121 change makes the evaluator safer at the cost of evaluation speed.
122 It handles the case when the user has added a non-immediate
123 improper end of the application form, e.g., `(+ 0 . x)'.
124 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
125 minimize the extra cost as much as possible. The new code is
126 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
127 problem with structs planted directly in the code (e.g. by a
128 macro). This no longer causes segmentation fault. (Thanks to
131 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
132 arg `proc' in order to be able to throw errors; New argument
135 * Removed extra #include "debug.h"
137 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
139 * scmsigs.c: Declare usleep as returning void on some systems.
140 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
143 * coop.c (usleep): Return void on some systems.
145 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
147 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
149 * coop.c: Changed return type of usleep to int.
151 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
152 isn't found in the OS.
154 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
155 isn't enabled. (Thought that I had made this change ages ago...)
157 * iselect.c: Declare bzero if not defined by OS.
159 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
161 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
162 condition. (Thanks to John Tobey.)
164 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
165 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
168 * __scm.h: Start the long-term project of moving to POSIX threads.
169 Phase 1: Classification of all critical sections.
170 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
171 for A sections. (See comments in __scm.h for details.)
173 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
174 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
176 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
178 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
179 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
180 (libpath.h, versiondat.h): Replaced dependency on Makefile with
181 dependencies on $(srcdir)/Makefile.in
182 $(top_builddir)/config.status in order to avoid circularity.
184 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
185 from argc if argc was 0 initially.
187 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
188 in generation of libpath.h.
190 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
192 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
193 libguile from 2 to 3.
195 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
197 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
199 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
201 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
202 scm_set_port_column_x, scm_port_filename,
203 scm_set_port_filename_x): Removed optional arguments. Added
204 proper argument checking.
206 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
207 stack size in machine words.
209 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
210 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
211 to Ole Myren Röhne.)
213 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
215 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
216 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
218 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
221 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
222 procedure apply: Copy argument lists before pushing them unto the
223 environment so that the environment won't get mutated due to
224 manipulation of procedure arguments. This should perhaps be
225 regarded as a temporary solution until someone finds a more
226 efficient one. (Thanks to Maciej Stachowiak.)
228 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
230 * script.c (scm_compile_shell_switches): Use "guile" as default
231 zero arg if argc is NULL.
233 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
235 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
236 is zero. (Thanks to Dirk Herrmann.)
238 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
240 * ports.c (scm_add_to_port_table): First line is now line 0
241 (was 1). (Interface changed according to suggestion by Per
244 * backtrace.c (display_header): Add 1 to line and column numbers
245 when presenting them to the user.
247 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
248 from debug.c --> eval.c
250 * eval.h, eval.c (scm_eval_options_interface): New options
252 (SCM_EVAL_STACK): New option: Size of newly created stacks,
253 i.e. stacks for new threads.
255 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
257 * eval.c (unsafe_setjmp): Removed with #if 0.
259 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
262 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
263 to avoid compiler warnings.
265 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
267 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
269 * throw.c (handler_message): Print message on current error port
270 instead of default error port. (Thanks to Maciej Stachowiak.)
272 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
274 * ports.c (scm_add_to_port_table): allocate in units of
275 struct scm_port_table *, not struct scm_port_table.
276 * posix.c (scm_close_pipe): remove the port from the port table
278 Thanks to Rob Engle for both fixes.
280 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
282 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
283 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
285 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
287 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
289 * backtrace.c (display_error_body, display_backtrace_body),
290 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
291 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
292 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
293 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
296 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
297 don't receive the jmpbuf arg anylonger.
298 (scm_catch): Don't accept a #f tag.
299 (scm_throw): Check that key is a symbol.
300 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
302 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
304 * async.c (async_pending): Removed declaration.
306 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
308 * dynwind.c (scm_wind_chain): New debug function.
310 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
311 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
312 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
313 extra layer of functions around the body and handler of a thread.
314 This extra layer makes sure that the handler is called in the
315 dynamic context of the surround (= empty dynwind list), but under
316 the *dynamic root* of the body. We can not use the dynamic root
317 of the surround since that root belongs to another thread => stack
318 is not handled correctly. It may seem ugly to use this extra
319 layer, but the extra cost in terms of execution time is really
320 negligible compared to the total amount of time required to create
321 a thread, and it would reduce maintainability to duplicate the
322 crucial and complicated steps performed by cwdr.
324 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
325 (SCM_ALLOW_INTS): Added thread switching code before interrupts
326 get re-enabled. The important effect of this is that interrupts
327 are blocked during thread switching so that thread data structures
328 don't risk getting messed up by an unfortunate signal.
329 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
330 seems to do more aggressive optimization which actually move
331 instructions around in these macros in a fatal way. Therefore:
332 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
333 just superstitious...)
334 (SCM_TICK): Maybe do a context switch and take care of asyncs.
335 This macro should be used instead of SCM_ASYNC_TICK since the
336 latter doesn't do context switches any more.
338 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
339 instead of SCM_ASYNC_TICK.
341 * coop.c, iselect.c: Since thread switches are now performed with
342 interrupts masked, we can't use the old mechanism of delivering
343 signals immediately when they arrive. Signals must instead be
344 delivered when the asyncs run *after* the end of the critical
345 section in scm_internal_select. But this also means after context
346 switch so that the signal will be delivered to a different thread.
347 To avoid this, I have changed the protocol of
348 coop_wait_for_runnable_thread and friends so that they are allowed
349 to return the original thread. So, if a signal arrives during
350 scm_internal_select, we won't any longer be forced do a context
351 switch, but can remain in the same thread and deliver the signal
354 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
355 scm_asyncs_pending and made it global.
357 * iselect.c: Small fixes.
359 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
360 coop_condition_variable_init, coop_condition_variable_wait,
361 coop_condition_variable_signal): Changed return type from `void'
362 to `int'. This is to adhere closer to the pthreads interface.
363 This, in turn, is part of an attempt to provide C versions of the
364 mutex and condition variable primitives which can be part of a
365 frontend to COOP or pthreads.
367 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
368 coop_condition_variable_destroy): New functions.
370 * coop-threads.c (scm_wait_condition_variable): Use
371 coop_condition_variable_wait_mutex.
373 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
374 Definitions moved to coop-defs.h.
376 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
377 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
378 scm_cond_destroy): New C interface to mutecis and cond vars.
380 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
382 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
384 * iselect.c: Now several threads can wait on the same file
385 descriptor. The behaviour is compatible with OS select: All
386 threads waiting for the fd return with the same status.
388 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
390 * coop-threads.c, threads.h (scm_spawn_thread): New function.
391 Can spawn a thread from application C code.
393 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
395 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
396 gh_doubles2scm): New functions.
398 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
400 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
401 commented-out version of gh_eval_str()
403 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
405 * socket.c (scm_bind): free soka after use.
407 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
409 * stime.c (tzvar): new variable.
410 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
411 avoid memory leaks when allocating.
413 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
415 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
418 * gc.c, tags.h: Doc fixes.
420 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
422 * eval.c (macro-eval!): Removed. This function was a design bug.
423 It allowed memoized code to leak out to the scheme level. Most
424 things that you could do with `macro-eval!' can be done with
427 1997-12-20 Tim Pierce <twp@skepsis.com>
429 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
430 scm_fgets now depends on ftell(3) to know how many bytes were
433 1997-12-15 Tim Pierce <twp@skepsis.com>
435 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
436 dealing with strings.
438 1997-12-13 Tim Pierce <twp@skepsis.com>
440 Make %read-line more suitable for implementing read-line efficiently.
441 * ioext.c (scm_read_line): Strip the terminating newline from a
442 string, and return a cons of the string and its terminator.
444 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
445 of the string that is read is stored in this memory location.
446 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
447 * genio.c, genio.h (scm_do_read_line): Update caller.
448 * ports.h (scm_ptobfuns): Update typedef.
449 * fports.c (scm_fptob, scm_pipob): Update struct.
451 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
453 * filesys.c (set_element): Return file descriptor.
454 (fill_select_type): Return the highest file descriptor.
455 (scm_select): Tell select about the highest file descriptor. On
456 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
457 Therefore the extra overhead for calculating the maximum fd seems
458 to be more than compensated. Is this correct? In any case,
459 scm_internal_select will be much faster with this info.
460 (scm_select, fill_select_type, set_element): Don't accept any kind
461 of object in the file descriptor list or vector.
463 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
465 * iselect.c (finalize_fd_sets): Bugfix.
467 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
469 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
470 when using scm_internal_select (since we might switch to another
473 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
475 * simpos.c (scm_system): always define: use sysmissing if not
476 available. Check for HAVE_SYSTEM instead of _Windows (does
477 Windows lack system or does it have an unusable one?).
478 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
479 Let the argument be optional: if not supplied, call system(NULL).
481 * ports.c (scm_close_port): relax the type check from OPPORTP to
482 PORTP; closing a closed port is allowed.
484 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
486 * fports.c (scm_fgets): Return if the last char in a chunk is
487 newline. When fgets returns a string whose length is `size-1', it
488 is ambiguous whether a whole line was retrieved, so we must check
489 explicitly whether a line terminator is present.
491 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
493 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
494 before taking the CDR. (Thanks to Harald Meland.)
496 * filesys.c (scm_stat): Slightly optimized.
498 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
500 * ports.c (scm_close_port): Make sure the port is open before
503 * guile-snarf.in: Pass args through to gcc in a way that preserves
504 whitespace boundaries. (Thanks to Greg Badros.)
506 1997-12-02 Tim Pierce <twp@skepsis.com>
508 * stacks.c (scm_frame_procedure): Reverse the logic in the return
509 statement. (Thanks to Doug Evans for pointing this out.)
511 1997-12-01 Tim Pierce <twp@skepsis.com>
513 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
515 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
517 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
518 errno macro expansion of this field name. (errno is a C
519 preprocessor macro on some systems.)
521 1997-11-29 Tim Pierce <twp@skepsis.com>
523 * iselect.c: Doc fix.
525 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
527 * init.c (scm_start_stack): Removed initialization of
528 scm_the_last_stack_var.
530 * backtrace.h: Declare scm_the_last_stack_var.
532 * backtrace.c: Define scm_the_last_stack_var.
534 * root.c (mark_root): Don't mark the_last_stack_var.
536 * root.h (scm_root_state): Removed the_last_stack_var.
538 * throw.c: Added #include "fluids.h"
539 (ss_handler): `the-last-stack' is now a fluid.
541 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
542 --> the_last_stack_fluid.
544 * backtrace.c: Added #include "fluids.h"
545 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
546 (scm_backtrace): `the-last-stack' is now a fluid.
548 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
549 after scm_init_fluids.

555 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
556 DLSYM_ADDS_USCORE to decide whether to add an underscore.
558 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
560 * iselect.c (coop_next_runnable_thread,
561 coop_wait_for_runnable_thread): Disable interrupts so that no
562 async is executed before a potential error_revive.
563 (scm_internal_select): Disable interrupts during the parts of the
564 code which manipulate the sleep queue and the file descriptors.
566 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
568 * Makefile.am: Added iselect.c and iselect.h.
570 * coop.c (coop_qinit): Initialize fields used by
572 (coop_qget, coop_qget, coop_tmp_queue): Made global.
573 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
574 replacement in iselect.c.
575 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
576 coop_join): If GUILE_ISELECT enabled, use
577 coop_wait_for_runnable_thread instead of
578 coop_next_runnable_thread.
579 (usleep, sleep): New replacements for system functions if
580 GUILE_ISELECT is enabled.
582 * coop-threads.h: Declare coop_wait_for_runnable_thread.
584 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
586 * filesys.c: Added #include "iselect.h". Moved FD-macros to
587 iselect.h. Implement Scheme level `select' using
588 scm_internal_select. (See NEWS.)
590 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
592 * init.c: Call scm_init_iselect.
594 * iselect.h, iselect.c: New files. Implements
595 scm_internal_select. (See NEWS.)
597 1997-11-27 Tim Pierce <twp@skepsis.com>
599 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
600 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
601 and scm_must_free, since ultimately the string returned will be copied
602 by scm_makfrom0str anyway. Also, read any characters that may have
603 been pushed onto the port with scm_ungetc.
604 * ports.c (scm_generic_fgets): Same as for scm_fgets.
605 * ioext.c (scm_read_line): Free string after Guilifying it.

617 gh_repl (argc, argv).
619 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
621 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
622 and to invoke scm_shell().
623 (gh_launch_pad): took out the loading of boot-9.scm from here,
624 since it is probably best to let the user control that. In fact,
625 gh_repl() now invokes scm_shell() which does that.
627 1997-11-23 Mark Galassi <rosalia@cygnus.com>
629 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
632 1997-11-22 Tim Pierce <twp@twp.tezcat.com>

635 yesterday's underscore patch. (Thanks to Marius Vollmer for
638 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
640 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if

646 (gh_uniform_vector_ref): started implementing the uniform types in
649 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
651 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
652 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
654 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
656 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
657 configure.in was changed).
659 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
661 * Makefile.am (modinclude_HEADERS): Include readline.h here.

664 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
666 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
667 OPORT is an `open' port, not an output port.
669 * filesys.c (scm_close, set_element, get_element, scm_chown,
670 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
671 SCM_COERCE_OUTPORT to cope with the printstate/port magic.

676 scm_close_all_ports_except, scm_set_current_output_port,
677 scm_set_current_error_port): Likewise
678 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
679 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
681 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
682 * backtrace.c (display_backtrace_body): Likewise
683 * fports (scm_setvbuf): Likewise
684 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,

687 * unif.c (scm_uniform_array_write): Likewise
689 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
691 Minor problems with substring-related tag changes.
692 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
693 exactly what we want to leave in to detect substrings.
694 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
695 * tags.h: Fix diagrams and comments describing the S tag bit;
696 remove vestigial remarks about the D tag bit.
697 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
698 * strings.c: Formatting tweaks.
700 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
701 variable first; then SCHEME_LOAD_PATH, with a warning message.
702 (scm_parse_path): New function.
703 * script.c: Doc fixes.
705 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
707 Readline support, from Daniel Risacher.
708 * readline.c, readline.h: New files.
709 * init.c: #include "readline.h".
710 (scm_boot_guile_1): Call scm_init_readline, if we have it.
711 * Makefile.am (libguile_la_SOURCES): Include readline.c.
712 * Makefile.in: Regenerated.
713 * scmconfig.h.in: Regenerated, after change to ../configure.
715 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
717 * gh.h: gh_vector_set -> gh_vector_set_x
719 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
721 * gh_data.c (gh_vector_set_x): changed name to make it consistent
722 with the ! -> _x mapping when going from Scheme to C.
724 1997-10-19 Mark Galassi <rosalia@cygnus.com>
734 (gh_assoc): added these gh_ functions implemented as macros.
736 * gh_predicates.c (gh_null_p):
737 (gh_string_equal_p): added these two missing predicates.
739 * gh_list.c (gh_append):
744 (gh_set_cdr_x): added these routines as I go through and try to
745 complete the picture R4RS functions that should be mirrored in the
748 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
750 * tags.h (scm_tc7_substring): Changed the comment and code to
751 conform with the changes below. Folks! We have suddenly two new
752 free tc7 codes!!! Jummy, jummy!
754 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
756 * Makefile.in: Rebuilt.

783 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
785 Don't include "mbstrings.h".
786 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
787 (SCM_SYMBOL_SLOTS): Define as 4.
788 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.

803 (scm_gen_putc, scm_gen_puts, scm_gen_write, scm_get_getc):
805 (scm_putc, scm_puts, scm_lfwrite): No longer static.
806 (scm_getc): No longer static; handle line and column changes.
807 (scm_ungetc): Renamed from scm_gen_ungetc.
808 (scm_do_read_line): Renamed from scm_gen_read_line.

816 * gh_test_c.c (c_vector_test): some improvements on the vector
819 * gh.h (gh_vector): this used to exist but do the wrong thing.
820 Now it (almost) does the right thing, though it takes a list
821 instead of the individual arguments. I need to see how it could
823 (gh_list_to_vector): added this function as a macro. Corresponds
824 to Scheme's (list->vector ...).
825 (gh_vector_to_list): added this function as a macro. Corresponds
826 to Scheme's (vector->list ...).
828 * gh_data.c (gh_vector_ref): renamed from gh_vref to
829 gh_vector_ref, so that it resembles the Scheme routines more.
830 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
831 resembles the Scheme routines more.
832 (gh_make_vector): this used to be (stupidly) called gh_vector().
833 This is the right name, since it does the same thing as the Scheme
834 (make-vector ...) procedure.
836 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
838 * ports.h: #include "libguile/print.h"

841 Some indentation fixes.
843 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
844 longer a user field; New field: class_flags.

848 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
850 * gh_data.c (gh_bool2scm): new function which replaces
851 gh_int2scmb(), which is now tagged as obsolete.
853 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
855 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
856 macros should by convention not test for NIMPness.)
857 (SCM_COERCE_OPORT): Adjust indentation.
859 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
860 SCM_NIMP test before SCM_PRINT_STATE_P.
862 * struct.c, struct.h, gc.c: Renamed:
863 scm_struct_i_layout --> scm_vtable_index_layout
864 scm_struct_i_vcell --> scm_vtable_index_vcell

866 scm_struct_i_printer --> scm_vtable_index_printer
867 scm_struct_i_vtable_offset --> scm_vtable_offset_user
869 * struct.c (scm_print_struct): Use new printer slot; Default
870 printing: Also output hex code of vtable so that type identity
871 will be indicated as well.
872 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
873 Removed struct_printer_var; Removed struct-vtable-offset;
874 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
875 vtable-offset-user): New constants.
877 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
878 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
879 If this slot contains a procedure, use that to print structures of
880 the type represented by this vtable.
882 * print.c (scm_iprin1): Don't print arguments of macro
883 transformers. (They are always: exp env.); Bugfix: Unmemoize
884 transformer source with correct environment.
886 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
888 Streamlining of call-with-dynamic-root:
890 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
891 there is now only one catch.
892 (cwdr_outer_body): Removed.
893 (cwdr_handler): New function.
894 (scm_internal_cwdr): New function to perform the function of cwdr
895 but take args that are more useful to C code. Also, the handler
896 is now invoked *outside* of the new dynamic root, like the docs
897 say. We no longer have to catch absolutely all errors, the caller
898 is responsible for using a handler that does not throw, if he
900 (cwdr): Reimplemented in terms of scm_internal_cwdr.
901 * root.h (scm_internal_cwdr): New prototype.
903 Even more but risky streamlining:
905 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
906 allocation of the jumpbuf of a root continuation. The changes
907 below are controlled by it. They are now deactivated.
908 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
909 the JMPBUF of the scm_rootcont to NULL before returning.
911 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
912 when they are non-NULL.
913 (scm_gc_mark): Likewise, mark only when non-NULL.
915 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
916 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
918 * gc.c (scm_done_malloc): New function.
919 gc.h (scm_done_malloc): New prototype.
921 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
922 (struct scm_print_state) [revealed]: New field.

928 a certain value is acceptable as a port argument.
929 (scm_print_state_vtable): New variable.
930 (scm_free_print_state): Set `revealed' field to false.
931 (scm_iprin1): Call user supplied closure printer with
932 scm_printer_apply. Print in the traditional way when there isn't
933 one or when it returns #f.
934 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
935 Accept a port/print-state pair in addition to just a port.
936 (scm_prin1): Don't return the print_state to the pool when it has
938 (scm_printer_apply): Set `revealed' field of print_state to true.
939 (scm_init_print): Set scm_print_state_vtable.
940 (print_state_fluid, print_state_fluid_num): Removed.
942 * throw.h (scm_handle_by_proc_catching_all): New prototype
943 throw.c (scm_handle_by_proc_catching_all): New function
945 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
947 * Makefile.in: Regenerated with automake 1.2c.
949 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
951 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
952 was looping endlessly.
954 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
956 * strports.c (scm_eval_string): Don't close the port.
958 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
959 former returns a nice normal integer. (Thanks to Daniel
962 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
964 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
965 makefile variable as a build parameter called LIBS. The
966 build-guile program will use this, for the time being.
967 * Makefile.in: Regenerated.
969 Thanks to Shiro Kawai:
970 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
971 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
974 * Makefile.in: Regenerated with automake 1.2a.
976 * script.c (scm_compile_shell_switches): If we hit the -c or --
977 arguments, don't set the car of (command-line) to scm_usage_name,
978 the prettified name of the guile executable; give it the full
979 path, the way shells usually handle $0.
981 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
983 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
984 Scheme-level name `array-map' and renamed `serial-array-map' to
987 * backtrace.c: Introduced exception handlers which now enclose
988 `display-error' and `display-backtrace' so that error reporting
989 won't get into infinite loops if an error occurs during displaying
990 of the error. This can very easily happen with user supplied
991 print call-back routines.
993 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
995 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
996 the names `serial-array-map' and `array-map' should be removed.)
998 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1000 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1001 Added #include "objects.h"
1003 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1004 Add #include "feature.h".
1006 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1007 (modinclude_HEADERS): Added objects.h.
1009 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1010 This test is needed at many places in the code and should be
1011 abstracted. (Motivated by the need of this test in libguiletk.)
1013 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1014 (scm_eval_string), load.c (scm_primitive_load,
1015 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1016 Use SCM_EOF_OBJECT_P.
1018 * eval.c (scm_init_eval): Add feature `delay'.
1020 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1022 * scmhob.h: Removed.
1024 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1026 * list.h (SCM_LISTn): New macros. Make list creation in C code
1027 prettier. The idea comes from STk.
1029 * sequences.h, sequences.c, append.h, append.c: Removed. These
1030 files implemented non-R4RS operations which would encourage
1031 non-portable programming style and less easy-to-read code.
1033 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1036 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1037 sequences.h, #include append.h.
1039 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and

1044 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1046 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1048 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>

1055 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1056 adjacent smob numbers.
1058 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1060 * procprop.h: Added declaration of scm_i_inner_name.
1062 * gsubr.c: New global symbol scm_i_inner_name.
1064 * debug.c (scm_procedure_name): Try procedure property
1065 `inner-name' if `name' fails.
1067 * print.c (scm_iprin1): Use scm_macro_name.
1069 * eval.c (scm_m_define): Give names to macros as well; Only the
1070 first top-level definition gives a procedure/macro a name.
1071 Otherwise confusing names can turn up in backtraces.
1072 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1073 `name'; Give names to macros as well.
1075 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1076 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1079 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1081 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
1083 (prinmacro): Removed. The code has been moved/merged into print.c
1084 in order to decrease code redundancy. We want macros to print in
1085 a way equivalent to procedures, and it would be silly to duplicate
1086 the required code. (We don't want to maintain two places.)
1087 (macrosmob): Print field is now a NULL pointer.
1089 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1090 scm_macro_transformer): New prototypes.
1091 (scm_tc16_macro): Declared.
1093 * * print.c (scm_iprin1): Added code for printing of macros. Macros
1094 are now printed in a way equivalent to procedures.
1096 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1098 * procs.h (scm_closure_p): Added declaration.
1100 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1102 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
1103 Shouldn't pass "heap" as the subr name.
1105 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1107 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
1108 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
1109 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1110 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1111 SCM_BOOL_T. Any non-false value is true.
1113 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1115 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1116 scm_gensym): Added prototypes.
1118 * symbols.c (scm_gensym): New function. This will speed up
1119 certain types of applications (such as macro systems) which
1120 generate lots of symbols.
1122 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1124 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
1126 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
1128 * unif.c (scm_shap2ra): tighten the checking of the array dimension
1129 specifier, since (2) or (2 . 3) would cause SEGV.
1130 (scm_transpose_array): more argument checking fixes.
1132 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1134 * Makefile.in: Regenerated.
1136 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1138 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
1140 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1142 * error.c, error.h (scm_error_callback): Removed (see NEWS).
1144 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
1146 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
1147 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
1150 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
1151 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1152 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
1153 scm_array_p, scm_array_rank, scm_array_dimensions,
1154 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
1155 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
1156 scm_array_prototype): Added case scm_tc7_wvect.
1158 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
1160 * errno.h: prototype for scm_strerror.
1161 * error.c (scm_strerror): new procedure.
1163 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1165 * list.c (scm_list_append_x): Allow non-pair as last argument.
1166 This is consistent with the R4RS append and is probably the
1167 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1169 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1171 * stime.h: prototype for scm_times.
1172 * stime.c (scm_times): new procedure.
1173 * ioext.c (scm_fseek): if the first argument is a file descriptor
1175 (scm_ftell): if the first argument is a file descriptor call lseek
1177 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
1178 * filesys.c (scm_chmod): if the first argument is a file descriptor,
1180 (scm_chown): if the first argument is a port or file descriptor,
1182 (scm_truncate_file): new procedure.
1183 Add DEFER/ALLOW INTS to a few other procedures.
1184 (scm_fsync): new procedure.
1185 (scm_open_fdes): new procedure.
1186 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
1188 (scm_fcntl): the first argument can now be a file descriptor. The
1189 third argument is now optional.
1191 * posix.c (scm_execl, scm_execlp): make the filename argument
1192 compulsory, since omitting it causes SEGV.
1193 (scm_sync): return unspecified instead of #f.
1194 (scm_execle): new procedure.
1195 (environ_list_to_c): new procedure.
1196 (scm_environ): use environ_list_to_c. disable interrupts.
1197 (scm_convert_exec_args): take pos and subr arguments and
1198 improve error checking.
1200 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1202 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1203 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1204 argument to SCM_ASSERT. Furthermore, the name of the function
1205 should be passed as first argument when signalling
1206 SCM_WNA. (Thanks to Thomas Morgan)
1208 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1209 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1210 dispatches on the number of actual args has a default case
1211 reporting an internal error. This is a vestige from a version
1212 that mallocated a SCM vector to hold the arguments. In the
1213 current version this check is too late: if it ever happens we will
1214 have already overstepped the bounds of the array.
1216 Also, the patch [...] adds a check for too many actual arguments."
1218 mdj: Removed check for "internal programming error".
1220 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1222 * gh_io.c (gh_write): New function.
1224 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
1225 throw.c (scm_internal_stack_catch): New sibling to the other catch
1226 functions. Code moved from gh_eval.c.
1227 throw.h: Added header.
1228 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
1229 scm_internal_stack_catch.
1231 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1233 * ioext.h: fix up prototypes.
1234 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
1235 Scheme name is now dup->fdes.
1236 (scm_dup_to_fdes): make the second argument optional and
1237 fold in the functionality of scm_primitive_dup.
1238 (scm_primitive_dup): deleted.
1240 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1242 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
1243 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
1244 ultrix are defined. Use setvbuf instead of setbuf.
1245 (scm_setvbuf): new procedure.
1246 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
1247 (scm_setfileno): moved from ioext.c.
1248 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
1249 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.

1253 * fluids.c (scm_fluid_p): New function.
1254 * fluids.h (scm_fluid_p): New prototype.

1258 * print.c (scm_iprin1): Enter printed structures into the print
1259 state as nested data while they are printed.
1260 (print_state_fluid, print_state_fluid_num): New variables.
1261 (scm_init_print): Initialize them.
1262 (scm_iprin): If print_state_fluid carries a print_state, use that
1263 instead of creating a new one.
1264 (scm_printer_apply, apply_stub, struct apply_data): New
1265 definitions to help with calling printer functions written in
1267 * print.h (scm_printer_apply): New prototype.
1269 * struct.c (scm_print_struct): Use scm_printer_apply to call the
1270 user defined struct printer.

1280 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
1281 SCM_ASSERT: arg comes before pos.
1283 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1285 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
1286 to a list of length zero correctly.
1288 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1290 Supply an `fgets' method for port objects to do fast line i/o.

1304 * ioext.h: removed scm_duplicate_port prototype.
1306 * ioext.c (scm_primitive_dup2): return the new file descriptor
1307 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
1309 (scm_fdopen): bug fix: don't try to make port unbuffered until its
1310 stream has been set.
1311 (scm_duplicate_port): deleted, there's now an implementation in
1313 (scm_primitive_dup2): do nothing if newfd == oldfd.
1315 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
1317 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the

1321 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
1323 * fluids.c (next_fluid_num): don't do
1324 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
1326 * ports.h: prototypes too.
1327 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
1329 * fports.h: prototype too.
1330 * fports.c (scm_evict_ports): moved from ioext.c.
1332 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
1334 * ports.c (scm_close_port): return a boolean instead of unspecified.
1335 throw an error if an error other than EBADF occurs.
1337 * filesys.h: scm_close prototype.
1338 * filesys.c (scm_close): new procedure, can close file descriptors
1339 and ports (scsh compatible).
1341 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
1344 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
1346 * fluids.c, fluid.h: New files.
1347 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
1348 (modinclude_HEADERS): Added "fluids.h"

1357 (scm_make_root): Call scm_copy_fluids to make fluid bindings
1358 unique for the new root when it has a parent.
1360 * smob.h: Include "libguile/print.h" to make scm_print_state
1363 * dynl.c (free_dynl_obj): New function to free the dynamic object
1364 data. (dynl_smob): Use it.
1365 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
1366 the dynamic object data below the linking of the object to avoid
1367 memory leak when the linking code throws an error. Now the code
1368 leaks a whole dynamically linked library when must_malloc throws,
1369 but that should be much less likely.
1371 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
1373 Changes to compile under gnu-win32, from Marcus Daniels:
1374 * stime.c (tzset): If tzset isn't provided, make it a NOP.
1375 (scm_localtime): Change SCM_EOF to SCM_EOL.
1376 (scm_mktime): Likewise.
1377 * socket.c: Don't include sys/un.h unless autoconf tells
1378 us Unix domain sockets are available.

1380 (scm_addr_vector): Likewise.
1381 (scm_init_addr_buffer): Likewise.

1389 (scm_setpwent): For setpwent.
1390 (scm_setegid): For setegid.
1391 * net_db.c (scm_inet_netof): Don't include unless support

1407 scm_misc_error, not SCM_EOF.
1409 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of

1411 think this is left over from the (eq? '() #f) days.
1413 * read.c (recsexpr): Give this a dummy definition if
1414 DEBUG_EXTENSIONS isn't #defined.
1416 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
1418 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
1421 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>

1428 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
1429 alloca.lo will be included in @LIBLOBJS@. Something better than
1430 this should be possible.
1431 * Makefile.in: Regenerated.
1433 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1435 * simpos.h: prototype for scm_primitive_exit.
1436 * simpos.c (scm_primitive_exit): new procedure, terminates the
1437 process without unwinding the stack.
1439 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
1441 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
1442 argument and logior its components together, so the user doesn't
1443 have to do this explicitly. Also, if regexp/basic is supplied, then
1444 turn off REG_EXTENDED.
1445 (scm_init_regex_posix): New regexp/basic symbol.
1446 (REG_BASIC): #define this if it is not already present.
1448 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

1459 years in usage message.
1461 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
1462 * Makefile.in: Regenerated.
1464 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
1465 flag; I don't think we support it.
1466 (scm_make_regexp): Make sure the user doesn't pass the
1469 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
1471 (scm_init_regex_posix): Define constants for the REG_mumble flags;
1472 name them according to the SCSH convention: regexp/mumble.

1479 Makefile directory variables. Print a message, but don't print
1481 (versiondat.h): Print a message, but don't print all the commands.
1482 * load.c: #include "alist.h".
1483 (init_build_info): New function.
1484 (scm_init_load): Call it.
1485 * Makefile.in: Regenerated.
1487 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
1489 * root.c: Establish a reliable catch-all handler for the new root.
1490 After all the Scheme handler function might signal an error too,
1491 and we don't want to lose that.
1492 (cwdr_inner_body): Renamed from cwdr_body.
1493 (cwdr_outer_body): New function, to establish the user's handler,
1494 and pass control to cwdr_inner_body.
1495 (cwdr): Establish the reliable catch-all handler here, and pass
1496 control to cwdr_outer_body.
1497 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
1498 the user's handler through to cwdr_outer_body.

1505 across this. Only works on GCC. Otherwise, we hope for the best.
1506 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
1507 the feeling that real thread systems will not need this...
1509 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
1511 Try to detect when people are using one version of libguile and a
1512 different version of ice-9. People have been skewing things and
1513 sending in bug reports.
1514 * Makefile.am (versiondat.h): New file to generate.
1515 * version.c: #include "versiondat.h", to get version info.
1516 (scm_libguile_config_stamp): New function.
1517 * script.c: #include "version.h".
1518 (scm_compile_switches): Call scm_version to get version number.
1519 * scmconfig.h.in, Makefile.in: Regenerated.
1520 * Makefile.in: Regenerated.
1522 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
1523 primitive definitions under their Scheme names.
1525 * Makefile.am (libguile_la_LDFLAGS): Update library version to
1526 1:2. Helps avoid confusion between installed and uninstalled libs.
1528 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
1531 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
1532 backslash from definition; this should be used like: GDB_INTERFACE;
1534 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1536 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
1537 new port unbuffered until its stream has been set.
1539 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
1541 * ports.h: new prototype.
1542 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
1544 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
1546 Make things compile neatly under Sun's C compiler.
1547 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
1548 * extchrs.c (xmbtowc): Make the second arg a normal char, not
1549 unsigned, because that's what the ANSI function takes.
1550 * extchrs.h (xmbtowc): Corresponding change to prototype.
1551 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
1553 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
1554 argument plain char *.
1555 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
1557 * tag.c (scm_tag): Remove unreachable statement.
1558 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
1559 top of the word, it should be unsigned.
1561 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
1562 is defined, to avoid warnings; it's only used in the
1563 conflict-checking code. Which might go away anyway.
1564 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
1565 conditionals; put the label definition in an #if too, to stifle
1568 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
1569 ChangeLog-threads in the distribution.
1570 * Makefile.in: Regenerated.
1572 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1574 * guile-snarf.in: Changed regexp to support CPPs that insert
1575 whitespace between lexical tokens (which munges the `%%%' snarf
1578 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1580 * load.c (scm_init_load_path): Append $(datadir)/guile to
1581 %load-path, so modules do not have to be installed in Guile's
1582 current version directory.
1584 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
1586 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
1587 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
1588 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
1589 call the sysdep functions with deferred ints.
1590 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
1591 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
1592 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
1595 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
1598 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
1600 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
1602 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
1604 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
1607 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
1609 * eval.c (scm_lookupcar1): New procedure to cope with a race
1610 condition during lookup (when using threads).
1611 (scm_lookupcar): Implement in terms of scm_lookupcar1.
1612 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
1615 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
1617 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
1618 supplied. (Change from Tim Pierce.)
1620 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
1622 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
1623 23:47:01 1997" changelog: Slots are now initialized with `#f' by
1624 default and not `()'. `#f' is the canonical non-value in Scheme,
1627 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1629 * struct.c (struct_printer): New variable that holds a handle on
1630 the Scheme variable *struct-printer*. This variable can be set by
1631 Scheme code to override the printing of structures.
1632 (scm_print_struct): If struct_printer is set, call it. If it is
1633 not set, or returns #f, print the structure in the old fashion.
1634 Include "eval.h" for scm_apply.
1636 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
1638 * struct.c (scm_struct_ref, scm_struct_set_x): Use
1639 scm_struct_i_n_words to get the number of fields, not
1640 -scm_struct_n_extra_words.
1642 On the route to fancier struct printing:
1643 * struct.c (scm_print_struct): New function to print a structure.
1644 Include "genio.h" to support it. This function doesn't do
1645 anything interesting right now, but I think it should be here
1647 * struct.h: Include "print.h" and add prototype for
1649 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
1650 print structures ourself.
1652 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
1654 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
1655 before applying the handler in case it doesn't return.
1657 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
1659 * scmsigs.h, async.h: updated.
1661 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
1664 * posix.c (scm_uname): interpret only negative values as an error.
1665 Solaris normally returns a positive value.
1667 * script.c (scm_compile_shell_switches): if we are not going into
1668 an interactive repl, set scm_mask_ints to zero so that asyncs can
1671 * simpos.c (scm_system): don't ignore/unignore signals around
1674 * posix.c (scm_open_pipe): don't ignore/unignore signals around
1677 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
1678 done in boot-9.scm instead.
1680 * scmsigs.c, async.c: Major rewriting of signal handling code.
1681 (scm_sigaction): new procedure.
1682 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
1684 (scm_raise): return unspecified, throw error on failure.
1686 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
1688 * regex-posix.c (scm_init_regex_posix): Register the "regex"
1689 feature, to help boot-9.scm decide whether to import the regex
1692 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
1694 * eval.c: Include scmconfig.h at the beginning of the file so that
1695 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
1698 * regex-posix.c: #include "_scm.h" before conditionally #including
1699 <regex.h>; the former defines HAVE_REGCOMP.
1701 * regex-posix.c: #include <regex.h> conditionally, so the file is
1702 CPP'able (for dependency scanning) even on systems that don't have
1705 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
1707 Add new R4RS-compliant syntax for keywords.
1708 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
1709 regardless of the setting of the `keywords' read option.
1710 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
1711 can be re-read no matter what the setting of the `keywords' read
1714 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
1716 Add support for POSIX regular expressions.
1718 * regex-posix.c, regex-posix.h: New files. (Some code
1719 is taken liberally from rx/rgx.c in the old Guile dist.)
1721 * init.c: Include regex-posix.h.
1722 (scm_boot_guile_1): Call scm_init_regex_posix.
1724 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
1725 Add regex-posix.[ch] sources.
1726 * Makefile.in: Regenerated.
1728 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
1729 to do this automatically? It didn't for me, bleh.)
1731 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
1733 * fports.c (print_pipe_port): New function.
1734 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
1735 latter doesn't even take the right arguments.
1737 * Makefile.am: Increment shared lib revision number. I think
1738 sometimes the uninstalled Guile finds the installed shared lib;
1739 Gord says doing this might help. As things turned out, I can't
1740 say whether it does.
1741 * Makefile.in: Regenerated.
1743 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
1744 passing it as the closure argument to scm_boot_guile. (Bill
1747 * ports.c (print_void_port, putc_void_port, puts_void_port,
1748 write_void_port, flush_void_port, getc_void_port, close_void_port,
1749 noop0): Use ANSI prototypes instead of K&R declarations, so the
1750 initialization of void_port_ptob gets aggressively type-checked.
1751 Fix arguments of print_void_port and write_void_port. (Bill

1785 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
1787 * script.c (scm_find_executable): Use prototype-style definition
1788 here; apparently it's not quite right to have const in a prototype
1789 and then use a K&R declaration. I wonder if stuff like this will
1790 go away if we compile with -Wrequire-prototypes, or whatever that
1791 is... (Bernard URBAN)
1793 * scmhob.h: New text from Bernard URBAN.
1795 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
1797 * script.c: Don't #define const on hpux. Configure takes care of
1798 this. (Thanks to Larry Schwimmer.)
1800 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
1801 decide whether to #include <unistd.h>, instead of listing a bunch
1802 of systems. Don't #include stdio twice. Removed dyked-out
1803 definition of scm_find_impl_file.
1805 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
1807 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
1808 library version info to 1:0.

1816 throw.c: Update copyright years; these files have been worked on
1817 significantly in 1997, but only had copyright years for 1996.
1818 Also, change name of copyright holder on some from Mikael
1819 Djurfeldt to Free Software Foundation; he has signed papers
1820 assigning the changes to the FSF.
1822 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
1823 reason not to give the user the option.
1825 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
1826 Return #f on end-of-file when scanning table (i.e. when called
1827 with no arguments). Try to catch errors, when we can.
1828 * posix.c (scm_getgrgid, scm_getpwuid): Same.
1830 * script.h (scm_shell_usage, scm_compile_shell_switches): New
1831 external declarations. These are useful.
1833 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
1835 * posix.c: don't include <sys/select.h> or define macros for
1836 select, since they were not used in this file.
1838 * filesys.c (scm_select): make the fifth parameter microseconds,
1839 not milliseconds. let the fourth parameter be either a real value
1840 or an integer or #f. The first, second and third arguments can
1841 now be vectors: the type of the corresponding return set will be
1843 (set_element, get_element): new static procedures.
1845 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
1847 * strports.c (scm_eval_string): New function.
1848 (scm_eval_0str): Trivially re-implemented in terms of
1850 * strports.h (scm_eval_string): New extern decl.
1852 * net_db.c (h_errno): Add extern decl for this.
1854 * fports.c (local_pclose): New function.
1855 (scm_pipob): Use it in the initializer here.
1858 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
1859 Use a meaningful error message when signalling an error. For
1860 this, scm_gethost must check h_errno rather than errno.
1862 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
1864 * Makefile.in: Regenerated, using automake-1.1p.
1866 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
1868 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
1869 not SCM_UNSPECIFIED.
1871 * script.c (scm_compile_shell_switches): don't append (quit) if
1873 (scm_shell): call scm_exit_status and exit on the result of the
1876 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
1878 Ensure that shared substrings are handled properly when passed to
1879 a system call or other foreign function. Many thanks to Tim
1881 * symbols.h (SCM_COERCE_SUBSTR): new macro.
1882 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
1883 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
1884 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

1896 SCM_COERCE_SUBSTR to make sure shared substrings are
1899 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
1901 * error.c (scm_error): Add newline to error message.
1903 * init.c (scm_init_standard_ports): Doc fix.
1905 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1907 * dynl-shl.c: Completely replaced with new code from Bernard
1910 * script.c (scm_ice_9_already_loaded): New variable.
1911 (scm_compile_shell_switches): Use it.
1913 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1915 * filesys.c (scm_input_waiting_p): add missing third argument to
1918 * stime.c (scm_localtime): copy the result of localtime before
1919 calling gmtime in case they share a buffer.
1920 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
1923 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
1925 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
1927 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
1929 * Makefile.am (check-local): New target, which causes 'make check'
1930 to run gh_test_c and gh_test_repl, with some trivial input.
1931 * Makefile.in: Rgnrtd.
1933 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
1935 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
1938 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
1940 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
1941 sure how this was supposed to work.
1942 (scm_async_click): don't send SCM_TICK_SIGNAL.
1943 (scm_init_async): don't initialize %tick-thunk.
1945 * the following change doesn't affect the Scheme interface:
1946 gc-thunk is called at the end of garbage collection. however it's
1947 no longer implemented by pretending it's a signal.
1949 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
1950 system async corresponding to scm_gc_thunk.
1951 * async.h: declare scm_gc_async.
1952 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
1953 gc-thunk directly, instead of going through a signal handler.
1954 (scm_gc_async): new variable, points to the GC system-async.
1955 (scm_init_async): save the GC async as scm_gc_async instead
1956 of using system_signal_asyncs.
1957 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
1959 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
1961 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
1962 Don't screw up if we're interrupted.
1963 * Makefile.in: Regeneradet.
1965 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
1967 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
1969 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
1970 we're not using AM_INIT_GUILE_MODULE any more.
1971 * Makefile.in: Reneregated.
1973 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
1975 Functions for finding variable bindings, grace à Tim Pierce.
1976 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
1977 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
1979 Get 'make dist' to work again.
1980 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
1981 * Makefile.in: Regenerated, like a surry without a fringe on top.
1983 Changes for reduced Guile distribution: one configure script,
1985 * configure.in, configure: Removed.
1986 * acconfig.h, acinclude.m4: Moved to parent directory, where the
1987 real configure script lives.
1988 * Makefile.in, scmconfig.h.in: Regenerated.
1990 * init.c: #include "script.h", to get prototype for script.c's
1993 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
1995 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
1996 scm_must_malloc, not raw malloc.
1998 * script.c (scm_compile_shell_switches): Dyke out debugging output
2001 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2003 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2005 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2006 system has them. Hope this is safe. Previously
2007 sys/timeb.h was included if HAVE_FTIME was defined or if
2008 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2009 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2011 * ioext.c (scm_setfileno): add missing third argument to
2012 scm_misc_error call.
2014 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2016 * eq.c (scm_equal_p): Correctly compare strings of different
2017 varieties. (Thanks to Tim Pierce.)
2019 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2021 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2022 #! block comment must occur on a line all by itself.
2024 Move most of the guts of shell command processing into libguile,
2025 so guile.c can be very small (and eventuallly auto-generated. (I
2026 mean, generated mechanically, not self-generated. Hmm.))
2027 * guile.c, script.c, script.h: New source files.
2028 * init.c (scm_boot_guile_1): Call scm_init_script.
2029 * libguile.h: #include "script.h".
2030 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2031 targets, for new executable.
2032 (libguile_la_SOURCES): Mention script.c.
2033 (modinclude_HEADERS): Add script.h.
2034 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2035 not dynamic linking is enabled. This is because we're generating
2036 executables now. Move CY_AC_WITH_THREADS call after those, so the
2037 values of cy_cv_threads_libs captures the libs chosen above.
2038 * Makefile.in, configure, aclocal.m4: Regenerated.
2040 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2041 We don't maintain this interface any more, and it just confuses
2044 * alloca.c: #include <scmconfig.h>, not <config.h>.
2045 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2046 it'll get included in disties.
2048 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2050 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2051 be distributed, because they confuse people.
2052 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2054 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2056 * configure.in: check for presence of gethostent (not present on
2057 OpenBSD by default).
2058 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2059 * configure, scmconfig.h.in: Regenerated.
2061 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2063 * backtrace.c (scm_backtrace): Split message string across
2064 newlines properly. GCC is more tolerant of this than other

2073 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2075 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2076 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2077 coop-threads.c.cygnus, coop-threads.h.cygnus.
2078 * configure.in: If we're using threads, include threads.o in
2080 * _scm.h, libguile.h: threads.h lives in this directory now.
2081 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2082 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2083 currently used, but brought along for information's sake.
2084 * ChangeLog-threads: log from old 'threads' directory.
2085 * Makefile.in, configure: Rebuilt.
2087 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2089 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2092 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2094 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2096 Merge GH interface library into libguile.
2097 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
2098 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2099 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2100 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2102 (EXTRA_libguile_la_SOURCES): ... here.
2103 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2104 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2105 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2106 New variables, describing how to build the gh test programs.
2107 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2108 build the test programs, and we probably should have been linking
2109 libguile.la against them all along, to support AIX shared libs.
2110 Add cflags for threads to CFLAGS; add libs for threads to new
2111 variable THREAD_LIBS, used in Makefile.am.
2112 * ChangeLog-gh: log from old `gh' subdirectory.
2113 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2115 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2117 * acconfig.h: Undo change of Apr 9; including the definition of
2118 PACKAGE in the guile headers conflicts with applications' own
2120 * scmconfig.h.in: Regenerated.
2122 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

2131 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2133 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2134 have S_IFSOCK. This is the case under Ultrix.
2136 * posix.c (scm_status_exit_val, scm_status_exit_val,
2137 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2138 Ultrix versions of WIFSTOPPED, etc., which assume that their
2139 arguments are lvalues (hmm).
2141 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2143 * eval.c: Doc fixes.
2145 * throw.c: Doc fixes; rearranged.
2147 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
2149 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
2151 * acconfig.h: Added entry for PACKAGE.
2152 * scmconfig.h.in: Regenerated.
2154 Changes to work with automake-1.1n, which has better libtool support.
2155 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2156 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
2158 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
2160 * Makefile.in: Rebuild.
2162 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2164 * stime.c (scm_mktime): take an optional zone argument.
2165 (scm_localtime): check putenv return value.
2166 (scm_strftime, scm_strptime): moved from posix.c. move #include
2168 stime.h, posix.h: update prototypes.
2169 (bdtime2c, setzone, restorezone): new static procedures.
2170 (scm_mktime, scm_strftime): use them.
2171 (scm_strftime): don't call mktime before strftime. Use
2172 filltime for return value.
2173 (filltime): convert NULL zname to #f.
2174 (scm_strptime): return a count of characters consumed, not
2175 the remaining string.
2177 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2179 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
2180 (scm_mktime): likewise.
2182 Uncomment localtime and mktime.
2184 * configure.in: add AC_STRUCT_TIMEZONE.
2186 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2188 * stime.c (scm_init_stime): don't define ticks/sec.
2189 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2190 return value problem and is still portable.)
2192 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2194 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2195 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2196 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2197 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2198 cpp_err_symbols.c): Corresponding changes.
2199 * Makefile.in: Regenerated.
2201 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2203 * posix.c (scm_putenv): don't check HAVE_PUTENV.
2204 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
2205 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
2206 * putenv.c: new file, from sh-utils 1.12.
2208 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2209 since allocation isn't for Scheme objects.
2210 (scm_putenv): copy strings before placing in the environment.
2212 * stime.c (scm_current_time): throw an error if time returns -1,
2213 instead of returning #f.
2214 (scm_get_internal_real_time, scm_get_internal_real_time): use
2215 scm_long2num for return value instead of SCM_MAKINUM.
2217 * stime.h: prototypes updated.
2219 * stime.c (scm_time_in_msec): apparently unused, deleted.
2221 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2223 * configure.in: check for gettimeofday.
2225 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2226 which may be more usefully portable than a gettimeofday interface.
2228 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2230 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not

2234 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2236 * stime.c (filltime): recovered static procedure.
2237 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
2240 * posix.h: add prototype for scm_close_pipe, remove prototypes for
2241 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2243 * posix.c (scm_mknod): split the mode argument into type and perms
2244 arguments, like the extra fields returned by stat.
2246 * fports.c (scm_pipob): set the close, free and print procedures.
2247 (scm_close_pipe): new procedure.
2249 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2250 define them in boot-9.scm
2252 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2254 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
2255 wan't defined. Don't include fd.h.
2257 * Previously fd.h was regenerated whenever configure was run,
2258 forcing a couple of files to be recompiled.
2260 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
2261 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
2262 Check for _fileno as well as _file.
2264 * ioext.c: don't fd.h.
2265 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
2268 * Change the stratigy for getting information about errno
2269 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
2270 generating lists of symbols during the build process, which will
2271 not always work, include comprehensive lists in the distribution.
2272 To help keep the lists up to date, the "check_signals" and
2273 "check_errnos" make targets can be used.
2275 * configure.in: don't check for a command to extract errno codes.
2276 * Makefile.am: update file lists, remove errnos.list and errnos.c
2277 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
2278 check_errnos targets.
2279 (CLEANFILES): remove errnos.c and errnos.list, add
2280 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
2281 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
2282 * errnos.default: deleted.
2283 * cpp_signal.c: new file.
2284 * cpp_errno.c: renamed from errnos_get.c.
2285 * cpp_err_symbols, cpp_sig_symbols: new files.
2286 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
2287 * error.c (scm_init_error): #include cpp_err_symbols instead of
2289 * posix.c (scm_init_posix): don't intern signal symbols. #include
2292 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
2294 * strop.c (scm_i_index): allow the lower bound to be equal to the
2295 length of the string, so a null string doesn't always give an error.
2297 * posix.h: new prototypes.
2298 * posix.c (scm_status_exit_val, scm_status_term_sig,
2299 scm_status_stop_sig): new functions, as in scsh. They break down
2300 process status values as returned by waitpid.
2302 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
2304 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
2305 configure doesn't know about it.
2307 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2309 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
2311 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
2312 which defines C variables with global linkage.
2314 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2316 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
2319 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
2321 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
2322 has time to check why this doesn't work well with continuations.
2324 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
2326 * Fix shell syntax error; some shells won't tolerate
2327 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
2329 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2331 * posix.c (scm_uname): throw an error if uname fails instead
2334 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
2336 * error.c (err_head, scm_errno, scm_perror): obsolete procedures

2341 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2343 * acconfig.h: Removed PACKAGE.
2345 * scmconfig.h.in: Regenerated.
2347 * snarf.h: g++ says it's non-portable not to specify the first
2348 argument in a varargs declaration. I introduced the first
2349 argument by using preprocessor conditionals.
2351 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
2353 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
2354 (scm_freopen): use RO string macros for filename and modes.
2355 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
2357 * posix.c (scm_getgrgid): simplify conversion of name to C string.
2358 (scm_mknod): use RO string macros for path.
2360 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
2361 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
2363 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2364 use SCM_ROSTRINGP and SCM_ROCHARS.

2368 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
2371 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,

2373 support for byte vectors.
2375 * print.c (scm_iprin1): Limit number of vector elements printed
2376 according to pstate->length.
2378 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2380 * backtrace.c (scm_display_error_message): don't segv if message
2383 * error.h: prototype for scm_error_scm.
2385 * error.c (scm_error_scm): new procedure, reimplements scm-error
2386 in C and uses scm_error.
2388 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2390 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
2391 pointer to the Scheme variable read-hash-procedures and intern it
2392 in scm_init_read. Modify scm_read_hash_extend and
2393 scm_get_hash_procedure to use the pointer.
2395 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2397 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
2398 (SCM_KEYWORD_STYLE): defined.
2400 * read.c (scm_read_opts): add a keywords option. This isn't a
2401 boolean option, in case someone wants to add support for DSSSL
2403 Setup scm_keyword_prefix symbol.
2404 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
2406 I've left keyword support disabled by default, since it doesn't
2407 seem to break the module system and it gives R4RS standard behaviour.
2408 It can be reactivated with (read-set! keywords 'prefix).
2410 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2412 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
2413 before constructing arbiter.
2415 * eval.c (scm_m_define): Bugfix: Check that the object is a
2416 closure before setting the procedure property!
2418 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
2420 * ports.c: Removed `ungetc-char-ready?'.
2422 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
2424 * read.c (scm_init_read): intitialise scm_read_hash_procedures
2425 (idea from Mikael: make it a pair so scm_permanent object only
2427 (scm_read_hash_extend): don't call scm_permanent_object.
2428 (ideas from Mikael): if chr is already in the list, replace its
2429 procedure instead of appending it again. If proc is #f, remove
2431 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
2433 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
2435 * gdbint.c (gdb_read): update scm_lreadr usage.

2439 * load.c (scm_primitive_load, scm_read_and_eval_x,
2440 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
2442 * read.h: add prototype for scm_read_hash_extend. Change args for
2445 * read.c (scm_read_hash_procedures): new variable.
2446 (scm_read_hash_extend): new procedure.
2447 (scm_get_hash_procedure): new procedure.
2448 (scm_lreadr): use scm_get_hash_procedure instead of an argument
2449 for extended # processing.
2450 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
2451 scm_read_token): remove case_i, sharp arguments. Change callers.
2453 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
2455 * read.h (SCM_N_READ_OPTIONS): increase to 3.
2456 (SCM_CASE_INSENSITIVE_P): define.
2458 * read.c: add case-insensitive option to scm_read_opts.
2459 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
2460 to determine whether to convert symbol case.
2461 (default_case_i): definition removed.
2462 * read.c (scm_read_token): if case_i, downcase ic before doing
2465 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2467 * configure.in: Added configuration option `guile-debug'.
2468 Configure with --enable-guile-debug if you want a bunch of extra
2469 functions used for debugging when developing Guile.
2471 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
2473 * procs.c (make-cclo): New undocumented debugging procedure: Make
2474 compiled closure with internal procedure PROC and length LENGTH.
2475 Only compiled if GUILE_DEBUG is defined.
2477 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
2479 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
2481 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
2483 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
2484 with 3 or more args internally to the evaluator.
2486 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2488 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
2489 with 3 or more args internally to the evaluator. This is mainly
2490 because we don't want to pass entry and exit points of the
2491 debug support twice, but it also seems to increase the speed of
2492 the evaluator for such calls (e. g. (+ 1 2 3)).
2494 * backtrace.c (scm_display_application): New procedure:
2495 display-application; Set fancy printing parameters individually
2496 for different types of display (backtrace, error, application).
2497 (These should of course be customizable!)
2499 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
2500 clear the CHECK-flags.
2502 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2504 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
2506 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2508 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
2509 from pairs with a GLOC in the car.
2511 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
2512 otherwise `symbol-hash' will behave badly.
2513 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
2514 we get segmentation fault!
2516 * symbols.c: Added #include "weaks.h". New functions:
2517 `builtin-bindings' and `builtin-weak-bindings'. (These will be
2518 moved to an extraneous library when we split libguile.)
2520 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2522 * filesys.c (scm_stat): stat now takes fport arguments too as
2523 documented in the manual.
2525 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2527 * debug.c (scm_single_step): Bugfix: Call continuation with
2528 scm_call_continuation instead of throwing to it.
2530 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
2532 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
2533 argument wasn't declared to be optional.
2535 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2537 * stime.c (scm_init_stime): Add feature "current-time".
2539 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
2541 * throw.h: prototype for scm_exit_status.
2542 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
2543 args to derive an exit status. Allows (quit) to work from a
2545 (scm_exit_status): new function.
2548 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2550 * eval.c (scm_deval): Removed some old code.
2551 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
2553 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
2556 * symbols.c (msymbolize): Bugfix: Must initialize property list to
2559 * procs.c: Introduce the existent C function scm_thunk_p at the
2560 Scheme level as well.
2562 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2564 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
2565 used from C to easily lookup the value of a symbol in the current
2568 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2570 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
2571 scm_init_unif in this file. This will also fix a previous problem
2574 * configure.in: Added AM_MAINTAINER_MODE
2576 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2578 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
2581 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
2583 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
2584 source files that are not always included in libguile but should
2585 have their dependencies calculated by automake. This variable is
2586 recognized by automake, no further magic is needed.
2587 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
2588 to deal exclusively with *.lo files, as it seems. The *.o files
2589 are built automatically when the corresponding *.lo file gets
2592 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
2594 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
2597 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
2599 * unif.c (scm_array_set_x): minor change to argument error checking.
2601 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
2603 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
2604 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
2605 They should only be included in the library at configure.in's
2607 (libguile_la_LDADD): Include the appropriate .lo files here.
2608 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
2609 so we know when to build them (and their .lo bretheren).
2610 * configure.in (LIBLOBJS): New substituted variable. We let
2611 configure decide which .o files to include in LIBOBJS, and then
2612 put the corresponding list of .lo files in LIBLOBJS. The latter
2613 is what we pass to libtool.
2614 * Makefile.in, configure: regenerated.
2616 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
2618 * symbols.c (scm_sysintern0): New function. Contains the core of
2619 old scm_sysintern but doesn't take a second value argument.
2620 (scm_sysintern): Now uses scm_sysintern0.
2621 (scm_sysintern_no_module_lookup): Renamed to
2622 scm_sysintern0_no_module_lookup and doesn't take a second value
2623 argument any longer.
2625 * symbols.h (scm_sysintern0: Added declaration.
2627 * options.c (scm_init_opts): Use scm_sysintern0 instead of
2628 scm_sysintern when interning option keys. Otherwise we risk
2629 destroying the values of already interned variables.
2631 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
2632 scheme-level boolean (use SCM_NFALSEP).
2634 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
2636 (scm_backtrace): New function. (C version of old function from
2637 boot-9.scm) Motivation: Make it possible to display backtraces
2638 without depending on boot-9.scm. (I'm uncertain if this
2639 motivation is good enough...)
2641 * root.h (scm_root_state): Add member the_last_stack_var.
2642 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
2644 * root.c (mark_root): Mark scm_the_last_stack_var.
2646 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
2649 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
2651 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
2652 1. mark_lazy_catch didn't mark the smob.
2653 2. Both functions above have standard variants:
2654 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
2655 free_lazy_catch --> scm_free0.
2657 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
2659 * throw.c (scm_internal_lazy_catch): New function.
2660 (scm_lazy_catch): Rewritten to use it.
2661 (scm_ithrow): Handle the new lazy catch representation.
2662 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
2663 that doesn't have a jmpbuf is a lazy catch clause.
2664 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
2665 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
2666 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
2668 (scm_init_throw): Register the new lazy-catch smob type.
2669 * throw.h (scm_internal_lazy_catch): decl for new function.
2671 * throw.c (scm_internal_catch): Doc fixes.
2673 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
2674 configure.in. Including this might cause problems if applications
2675 that link against libguile include their own copies of alloca, but
2676 if they're using autoconf, they should be adding libguile to LIBS
2677 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
2678 the copy in libguile, and things will be okay. (I think.)
2680 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2682 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
2684 strop.h: move prototypes too.
2686 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2688 * posix.c (scm_init_posix): don't intern EINTR since it's now done
2691 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
2692 etc. I deleted them from filesys.c long ago, but didn't
2693 notice they were here too (although ineffective since
2694 sys/stat.h wasn't included).
2696 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
2698 * eval.c: Don't define alloca in GCC case. gcc will automatically
2699 use __builtin_alloca if appropriate.
2701 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2703 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
2704 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
2705 that values of automatic variables are preserved. See comments
2706 for safe_setjmp for details.
2708 Change from Thomas Morgan:
2709 * variable.c: Include eq.h.
2710 (var_equal): New function.
2711 (variable_smob): Use var_equal as the discriminator for variables.
2713 * throw.c (s_throw): Remove extraneous declaration.
2715 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
2716 * eval.c: Add necessary CPP cruft to support that.
2717 * configure, Makefile.in, scmconfig.h.in: regenerated.
2719 Change from Thomas Morgan:
2720 * procprop.c (scm_procedure_properties): Convert the Scheme
2721 boolean returned by scm_procedure_p into a C boolean before using
2722 it as a condition for SCM_ASSERT.
2723 (scm_procedure_property): Likewise.
2725 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
2726 indications of Unixness.
2729 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2731 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
2733 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2735 * read.c (scm_lreadr): use scm_misc_error to improve one of the
2736 "unknown # object" error messages.
2738 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
2739 (scm_i_index) and declare it static. Add a 'direction' argument
2740 to indicate what way the search should go.
2741 (scm_i_index): throw out-of-range error instead of wrong-type-arg
2743 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
2744 strop.h: remove scm_i_index, scm_i_rindex prototypes.
2746 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2748 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
2750 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
2751 to avoid clash with various scsh forks.
2753 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
2755 The following two changes (ramap.c, throw.c) are motivated by the
2756 apparent unportability of forward declarations of static arrays of
2757 the form `static foo bar[];'.
2759 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
2760 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
2762 * throw.c (scm_throw): Moved above scm_ithrow.
2764 * options.h: Removed the extern declarations of scm_yes_sym and
2765 scm_no_sym since these are static.
2767 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2769 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
2771 * Makefile.am: remove AWK=@AWK@.
2772 Add a rule for generating errnos.list.
2773 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
2775 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
2776 don't extract errnos, just set a variable (avoids the
2777 need to recompile error.c just because configure is run.)
2779 * unif.h: update prototypes.
2780 * unif.c (scm_uniform_array_read,write): change the offset and
2781 length arguments to start and end, for consistency.
2783 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
2785 * ioext.h: update prototypes.
2786 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
2787 scm_read_line_x, it's a more general procedure using an
2788 interface from scsh. read-line and read-line! are now defined
2790 Note that the new read-line trims the terminator
2791 by default, previously it was appended to the returned string. An
2792 optional argument specifies how to process the terminator (scsh
2793 compatible). For the old behaviour: (read-line port 'concat).
2794 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
2795 returns a pair, but is converted to multiple values if the scsh
2798 socket.h: update prototypes.
2799 * socket.c (scm_recvfrom): for consistency with other procedures,
2800 take start and end as separate optional arguments.
2801 (scm_recv, scm_recvfrom): don't allow the second argument
2802 to be a size, only a buffer. Change the scheme names to
2803 recv! and recvfrom!. Don't return the buffer.
2805 * ioext.h, posix.h: move prototypes too.
2806 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
2807 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
2808 "read.h" and "unif.h".
2809 * ioext.c: include "chars.h"
2811 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
2813 * dynl.c: The dynamic linking and module registration functions
2814 are now defined even when dynamic linking is not available for the
2815 host system. Some of their functionality can be done without
2816 dynamic linking; when it's really needed, they throw errors.
2818 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
2820 * configure.in: Only define DYNAMIC_LINKING when one of the system
2821 dependent functions is detected.
2822 * dynl.c (scm_dynamic_func): New function to get the address of a
2823 function in a dynamic object.
2824 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
2825 produced by scm_dynamic_func as the thing to call.
2827 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
2829 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
2830 (scm_register_module_xxx, scm_registered_modules,
2831 scm_clear_registered_modules): New functions.
2833 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
2835 * symbols.c (scm_sysintern): Renamed to
2836 scm_sysintern_no_module_lookup.
2837 (scm_sysintern): New function to take the place of the old
2838 scm_sysintern. It uses the current toplevel lookup closure to give
2839 the symbol its value. This is a temporary hack to put packages
2840 like gtcltk into their own module.
2841 (scm_can_use_top_level_lookup_closure_var): New variable to tell
2842 us whether `scm_top_level_lookup_closure_var' has been initialized
2844 * eval.c (scm_init_eval): Set it.
2846 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
2848 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
2849 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
2851 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
2853 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
2854 scm_sys_dup): deleted: FD capability will be added to other
2856 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
2857 scm_fd_free, fd_smob, scm_intern_fd.
2858 (scm_open): renamed from scm_sys_open. Return a port instead of
2859 an FD object. Make the mode argument optional.
2860 (scm_sys_create): deleted, it's just a special case of open.
2861 (scm_init_filesys): move interning of constants O_CREAT etc.,
2862 here (were previously using SCM_CONST_LONG macro).
2863 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
2865 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
2866 include "fports.h" and <stdio.h>
2867 (scm_stat, scm_select): don't support FD objects.
2869 * error.h: adjust scm_syserror_msg prototype.
2870 * error.c (scm_syserror_msg): take an extra argument for errno.
2871 Using the global value didn't always work, since it could be
2872 reset by procedure calls in the message or args arguments.
2874 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
2875 I don't understand why the check was there (and what about the
2878 * strop.c (scm_string_copy): allow shared substrings to be copied.
2880 * unif.h: corresponding change to prototypes.
2881 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
2882 recognize two new optional arguments: offset and length. Allow
2883 the port argument to be an integer (file descriptor, for scsh).
2884 Include <unistd.h> for "read" prototype.
2886 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2888 * socket.c: don't include filesys.h.
2890 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
2892 * Makefile.am: add AWK=@AWK@ (?)
2894 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
2896 Add a rule to generate errnos.c from errnos.
2897 * error.c (scm_init_error): include errnos.c.
2898 * errnos_cnvt.awk: new file, converts the list of errno codes to
2900 * errnos_get.c: new file.
2901 * errnos.default: new file, contains errnos to try if they can't
2902 be extracted from errno.h.
2903 * configure.in: if using GCC, try and extract errno codes from
2907 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
2909 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
2910 * Makefile.am: Made libguile into a libtool library.
2911 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
2912 Set libtool_libs to indicate that libguile is a libtool library.
2913 See guile/ChangeLog for details.
2914 * .cvsignore: ignore "*.lo", the libtool library objects.
2916 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2918 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
2919 use htons in getservbyport argument.
2921 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2923 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
2924 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
2927 * objprop.c (scm_object_property): No need to take the CDR of the
2928 value returned by scm_object_properties, since Aug 20 change.
2930 * configure.in: When checking for struct linger, #include
2931 <sys/types.h> as well as <sys/socket.h>. I've never known
2932 <sys/types.h> to cause any portability problems, and Solaris's
2933 <sys/socket.h> needs it.
2934 * configure: Rebuilt.
2936 I think the Sun compiler has chosen a perverse way to interpret
2937 ANSI declarations combined with K&R definitions. We'll
2938 appease it a little bit. But when it invades France, we fight.
2939 * print.c (scm_iprlist): Change 'tlr' argument to an int.
2940 * print.h (scm_iprlist): Here too.
2941 * numbers.c (scm_divbigdig): Change definition to match
2942 declaration in numbers.h.
2943 * unif.c (scm_makflo): Change definition to match declaration in
2946 * init.c (scm_boot_guile): Don't return the value of
2947 scm_boot_guile_1. This function doesn't return a value;
2948 scm_boot_guile_1 doesn't return a value (or return at all).
2950 * eval.c (unmemocopy): Add a semicolon to appease the Sun
2953 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
2954 compile. I have a feeling this function is a bad idea anyway ---
2955 one should always test for features, not systems.
2957 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
2958 semicolons. Only pure luck kept this from being noticed earlier.
2960 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
2962 * socket.c (scm_recvfrom): Added missing semicolon.
2964 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2966 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
2967 the buffer and start and end positions for scsh networking
2970 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
2972 * configure.in: Revert previous change to this file; the problem
2973 is due to transient automake weirdness.
2974 * configure: Rebuilt.
2976 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
2977 PLUGIN/guile.libs. configure generates the latter from the former.
2978 * Makefile.in: Rebuilt.
2980 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
2981 need this if we install scripts, like guile-snarf.
2982 * configure: Rebuilt.
2984 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
2986 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
2988 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
2990 * socket.c (scm_addr_vector): fix faulty scm_listify.
2992 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
2994 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
2995 style block comment is no longer considered an error.
2997 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
2999 * PLUGIN/guile.libs.in: New file.
3000 * PLUGIN/guile.libs: Removed from repository.
3001 * configure.in: Create PLUGIN/guile.libs from
3002 PLUGIN/guile.libs.in. This is for including additonal libraries
3003 needed for dynamic linking.
3004 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3005 instead of PLUGIN/guile.libs.
3007 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3009 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3011 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3012 occurrences of the given element from the list, not just the
3013 first. This is how the Emacs Lisp functions behave, how the
3014 analogous Common Lisp functions behave, and (I believe) how the
3015 older Maclisp functions worked. I realize that this change may
3016 break code, but it seemed better to break it before the Guile
3019 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3020 Their prototypes were already present in gc.h, but they weren't
3022 (scm_init_storage): Initialize scm_protects.
3023 * root.c (scm_protects): New element of scm_sys_protects.
3025 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3027 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3029 * libguile.h: Added #include "libguile/net_db.h".
3031 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3032 30 change. That file is only meant for communication between the
3033 configuration process and load.c. If code linked against libguile
3034 wants to get at the paths mentioned in libpath.h, it can call
3035 functions declared in load.h.
3037 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3039 * libguile.h: Removed #include "libguile/fdsocket.h"
3041 * net_db.c: Added #include <sys/socket.h>.
3043 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3045 * filesys.c (scm_input_waiting_p): use select in preference to
3046 FIONREAD, since the latter doesn't detect EOF.
3047 Throw error if neither select nor FIONREAD available.
3049 * socket.c (scm_connect): take a port, not a fd object.
3050 (scm_fill_sockaddr): throw an error if fam is not recognised.
3051 (scm_bind): use scm_fill_sockaddr.
3052 (scm_listen): take a port, not a fd object.
3053 (scm_accept): take and return a port. return #f in the car if
3054 address can't be got
3055 (scm_sock_fd_to_port): new procedure.
3056 (scm_socket): use scm_sock_fd_to_port.
3057 (scm_addr_vector): throw error if unrecognised address type.
3058 take an extra argument with the calling procedure name.
3059 (scm_getsockname): take a port. return #f if address can't be got.
3060 (scm_getpeername): take a port. return #f if address can't be got.
3061 (scm_recvfrom): take a port. return #f for address component if can't
3063 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3064 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3066 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3068 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3069 use separate data pointers, to allow them to be designed
3070 independently and reused.
3071 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3072 Renamed from catch_body, catch_handler, and uncaught_throw; made
3074 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3076 (scm_catch): Use the above.
3077 (scm_throw): Don't bother printing a message for an uncaught
3078 throw; we establish a default handler in init.
3079 * throw.h (scm_internal_catch): Prototype updated.
3080 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3082 (struct scm_body_thunk_data): New structure, used as data
3083 argument to scm_body_thunk.
3084 * init.c (struct main_func_closure): New structure, packaging up
3085 the data to pass to the user's main function.
3086 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3087 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3088 scm_internal_catch to establish a catch-all handler, using
3089 scm_handle_by_message. This replaces the special-case code in
3091 (invoke_main_func): Body function for scm_internal_catch; invoke
3092 the user's main function, using the main_func_closure pointer to
3093 decide what to pass it.
3094 * root.c (struct cwdr_body_data): Remove handler_proc member.
3095 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3096 (cwdr_handler): Removed.
3098 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3100 * socket.h (SCM_P): update bind prototype.
3101 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3102 include "feature.h".
3103 (scm_socket): return a port, not a file descriptor object.
3104 include "fports.h" and <unistd.h>
3105 (scm_bind): take a port, not a file descriptor object.
3106 take an extra argument for address args.
3108 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3109 INADDR_NONE, INADDR_LOOPBACK.
3111 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3113 * init.c: include net_db.h and not fdsocket.h.
3114 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3116 * Makefile.am: corresponding changes.
3117 * socket.h: renamed from fdsocket.h, fix names.
3118 * net_db.h: renamed from socket.h, fix names.
3119 * socket.c: renamed from fdsocket.c.
3120 remove _sys from procedure names.
3121 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3122 add "socket" to features list.
3123 * net_db.c: renamed from socket.c.
3124 remove _sys from procedure names.
3125 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3126 add "net-db" to features list.
3127 include "net_db.h". don't include <sys/socket.h> or
3130 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3132 * tags.h (scm_tags): Removed comma at end of last enumerator.
3134 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3136 Don't use GCC extensions to allocate space for debugging frames.
3137 (Here he goes again! Why do we put up with this?!)
3138 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3139 an scm_debug_info structure, not an in-line array of them. Add
3140 'info' member, to say how many vect elements we've used, for eval
3142 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3143 a new variable debug_info_end to mark the end of vect, instead of
3144 the address of the 'info' pointer itself.
3145 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3146 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3147 (SCM_APPLY): Explicitly allocate space for debug.vect.
3148 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3149 * stacks.c: Adjusted for new debug frame structure.
3150 (RELOC_INFO, RELOC_FRAME): New macros.
3151 (stack_depth, read_frames): Use them, and new scm_debug_frame
3152 element 'info', instead of magically knowing that eval frames have
3153 an info pointer sitting after vect.
3154 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3156 (scm_init_stacks): Formatting tweaks.
3158 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3160 Give GCC more control flow information, so it can be sure that
3161 variables aren't used uninitialized.
3162 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3163 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3164 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3165 scm_misc_error): Tell GCC that these functions never return.
3166 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3167 out the field type, call abort if SCM_ASSERT returns, to placate
3169 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3170 scm_wta ever returns. We can't handle this case anyway, and this
3171 gives the optimizer more information.
3172 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3173 scm_wta ever returns.
3175 In some cases, the code is fine, but GCC isn't smart enough to
3176 figure that out; this usually happens when one variable is only
3177 initialized and used when a particular condition holds true, and
3178 we know that condition will never change within a given invocation
3179 of the function. In this case, we simply initialize the variables
3180 to placate the compiler, hopefully to a value which will cause a
3181 crash if it is ever actually used.
3182 * print.c (scm_iprin1): Initialize mw_pos.
3183 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3184 * throw.c (scm_ithrow): Initialize dynpair.
3185 * unif.c (scm_uniform_vector_ref): Initialize cra.
3186 * struct.c (init_struct): Initialize prot.
3187 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3189 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3190 if EXPR contains no expressions.
3192 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3194 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3195 cause an infinite loop (???). So much for the algebraic
3196 equivalency of variable-sized arrays and alloca...
3198 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3200 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3201 a SCM boolean, not a C boolean.
3203 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3205 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3206 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3207 rules for raising scm_mtrigger. Previously, unfortunate but not
3208 unlikely circumstances could result in almost constant invokation
3209 of the gc. Now, this situations should be less likely, but they
3210 are not prevented completely.
3212 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3214 * numbers.c (scm_fuck): Procedure removed; looks like old test
3216 * numbers.h: Prototype removed.
3218 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3220 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3221 array to a pointer, to match my Nov 21 change in eval.c.
3223 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3225 * libguile.h: Added #include "libguile/backtrace.h", #include
3226 "libguile/stacks.h".
3228 * strings.c (scm_string scm_make_string scm_string_ref
3229 scm_string_set_x scm_string_equal_p scm_string_append):
3230 Bugfix according to scm patch from Aubrey Jaffer:
3231 Corrected long-standing
3232 (not (eqv? (integer->char 128)
3233 (string-ref (make-string 1 (integer->char 128)) 0)))
3234 bug found by John Kozak <jk@noontide.demon.co.uk>.
3236 * strports.c, strports.h: Make scm_eval_0str return the value of
3237 the last expression evaluated (previously, it returned void).
3239 * strports.c, strports.h: New function: scm_read_0str. Does what
3242 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3244 * simpos.c (scm_getenv): return #f if string can't be found in the
3245 environment instead of throwing an exception, for compatibility
3246 with numerous other systems.
3248 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3250 * Makefile.am (.c.x): Use guile-snarf.
3251 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
3253 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
3255 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3257 * backtrace.c (scm_display_error_message): Made non-static, and
3258 renamed from display_error_message.
3259 * backtrace.h (scm_display_error_message): Added extern decl.
3260 * throw.c (uncaught_throw): Use it to display the error message.
3262 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
3264 * inet_aton.c: Use #if 0, not #ifdef 0.
3266 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
3268 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
3269 to convert the returned value.
3270 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
3271 the offset argument.
3273 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3275 Add new interface to catch/throw, usable from C as well as
3277 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
3278 (scm_internal_catch): New function, replaces...
3279 (scm_catch_apply): Deleted.
3280 * throw.c (scm_catch_apply): Deleted; replaced with a more general
3281 mechanism which is a bit more code, but can be used nicely from C
3282 and implement the Scheme semantics as well.
3283 (scm_internal_catch): This is the replacement; it's named after
3284 the analogous function in Emacs.
3285 (scm_catch): Reimplemented in terms of the above.
3286 (struct catch_body_data, catch_body, catch_handler): New
3287 functions, used by scm_catch.
3288 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
3289 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
3290 support for new cwdr.
3292 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
3295 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
3297 * acconfig.h: Added DYNAMIC_LINKING symbol.
3298 * configure.in: Add option and checks for dynamic linking.
3299 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
3300 dynl.h: New files for dynamic linking support.
3301 * Makefile.am (libguile_a_SOURCES):
3303 (modinclude_HEADERS): Added "dynl.h".
3304 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
3306 * init.c (scm_boot_guile_1): Call
3307 scm_init_dynamic_linking to initialize dynamic linking support.
3309 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
3311 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
3312 (as we Schemers say). It needs to be global, so that I can tweak
3313 it for the proper operation of unexec.
3314 (scm_boot_guile_1_live): New variable, see above.
3316 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
3318 * guile-snarf.sh: Removed.
3319 * PLUGIN/guile.libs: Added dependency for -lm.
3320 * acinclude.m4: Renamed from aclocal.m4.
3321 * PLUGIN/greet: Removed.
3322 * Makefile.am, aclocal.m4: New files.
3323 * configure.in: Updated for Automake.
3325 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
3327 * eval.c (scm_definedp): Use top_level_lookup_closure_var
3328 and not top_level_lookup_thunk_var.
3330 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
3332 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
3334 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
3336 * eval.c (scm_definedp): Incompatibly changed to be a builtin
3337 Scheme function, instead of syntax. Single argument is now a
3340 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3342 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
3343 scm_ra_divide): Properly terminate statements passed as arguments
3344 to IVDEP macros. (Thanks to Bernard Urban.)
3346 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
3347 with non-constant sizes. (Thanks to Bernard Urban.)
3349 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3351 It's an "eval closure", not an "eval thunk." A thunk is a
3352 function of no arguments.
3353 * root.h (struct scm_root_state): Renamed
3354 top_level_lookup_closure_var from top_level_lookup_thunk_var.
3355 (scm_top_level_lookup_closure_var): Renamed from
3356 scm_top_level_lookup_thunk_var.
3357 * root.c (mark_root): Uses changed.
3358 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
3359 * init.c (scm_start_stack): Uses changed.
3360 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
3361 Change scheme-visible name to *top-level-lookup-closure* from
3362 *top-level-lookup-thunk*.
3364 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
3366 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
3367 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
3369 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
3371 * gc.c (struct scm_heap_seg_data): Doc fixes.
3373 * gc.c (scm_gc_sweep): Empty all segments' freelists before
3374 sweeping. Then, prepend each segment's free cells to its
3375 freelist, rather than wiping out the old value. (Thanks to Marius
3378 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
3379 scm_check_freelist, scm_debug_newcell): New functions and
3380 variables, for debugging freelist problems.
3381 * pairs.h (SCM_NEWCELL): New debugging version added.
3382 * gc.h (scm_debug_newcell): Added extern declaration, used by
3383 debugging version of SCM_NEWCELL.
3385 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3387 On some systems <libc.h> conflicts with <unistd.h>, and should not
3388 be #included at all.
3389 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
3390 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
3391 * configure.in: Call it.
3392 * posix.c, filesys.c: Use its results to decide whether or not to
3394 * configure, scmconfig.h.in: Rebuilt with autoconf and
3397 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
3399 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
3400 pointer to the stdio stream before calling scm_setbuf0, so the
3401 latter will be able to retrieve it. I'm surprised this didn't
3402 segfault earlier. (Thanks to Christopher Lee.)
3404 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3406 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
3409 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3411 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
3412 number of stack narrowing specifier pairs. The first specifier in
3413 a pair controls inner border, the second the outer border. A
3414 number means cut that number of frames, a procedure object means
3415 cut until that object is found in operator position in a frame.
3417 * root.c (cwdr): Bugfix.
3419 * read.c: Recording of positions disabled by default.
3421 * procs.c (scm_closure_p): New function.
3423 * posix.c (scm_tmpnam): New function.
3425 * load.c: Added #include "throw.h".
3426 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
3429 * load.c, load.h (scm_read_and_eval_x): New function.
3431 * eval.c: Renamed debug option "deval" to "debug".
3433 (scm_eval_x): `eval!' is no longer accessible from the scheme
3434 level. Motivation: We can't allow operations which introduce
3435 glocs into the scheme level. Guile's type system can't handle
3436 these as data. Use `eval' or `read-and-eval!' as replacement.
3438 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
3439 SCM_CONSP since this is a macro!; Set vframe.prev to
3440 scm_last_debug_frame instead of 0. In this way we can look
3441 "above" the virtual start stack frame if we wish.
3442 (scm_debug_hang): New function: Useful for debugging Guile in
3443 certain tricky situations. Will probably be removed later...
3445 * debug.h: Changed semantics of debug option "backtrace". This
3446 option now only indicates whether we want automatic backtrace at
3449 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3451 * ports.c: #include "filesys.h"
3452 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
3454 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
3455 Motivation: This is system specific code which is related to file
3456 I/O. It also may use select. Added code by Gary Houston to
3457 detect presence of character in stdio buffers.
3459 * libguile.h: #include "libguile/libpath.h"
3461 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
3462 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
3463 SCM_SITE_DIR; Install libpath.h among the other include files.
3465 * load.c, load.h (scm_sys_package_data_dir): New function.
3467 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3469 * stacks.h: Bugfix: Don't use tail-array length field as stack
3470 length field! This screwed GC.
3472 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3474 * _scm.h: Added #ifndef around definition of macros min and max.
3476 * __scm.h: Added hooks for threads to plugin to in ints protection
3477 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
3478 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
3479 the main code in these macros duplicated and spread over multiple
3480 files. Renamed SCM_THREADS_SWITCHING_CODE ->
3481 SCM_THREAD_SWITCHING_CODE.
3483 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
3485 * snarf.h: New file.
3486 * guile-snarf.sh: New file.
3487 * Makefile.in (inner_h_files): Added snarf.h
3488 (ancillary, install, uninstall, distclean): Added actions for
3490 (.c.x): Use guile-snarf.
3491 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
3492 (gen_c_files): Note that these depend on guile-snarf.
3493 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
3494 now in "snarf.h". Added #include "snarf.h" to get them.
3495 * libguile.h: Added #include "snarf.h".
3496 (Patches applied and tweaked by Jim Blandy.)
3498 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
3500 * socket.c: Use K&R style declaration for 'close'; the GNU coding
3501 standards suggest against providing prototypes for system
3502 functions. Thanks to Greg Troxel.
3504 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3506 * strports.c (scm_eval_0str): New function.
3507 #include "read.h", to get prototype for scm_read.
3508 * Makefile.in (strports.o): Update dependencies.
3509 * strports.h: New prototype.
3511 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
3512 scheme name from "int?" to "integer?". It seems to do the job.
3513 * numbers.h: Rename prototype too.
3514 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
3517 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
3518 scm_num_eq_p): Rename these according to R4RS conventions: call
3519 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
3520 to making libguile R4RS compliant without ice-9...
3522 * load.c (scm_sys_search_load_path): Search for files under all
3523 extensions listed in the %load-extensions variable. If FILENAME
3524 is absolute, return it unchanged, without searching the load path.
3525 (scm_loc_load_extensions): New variable, pointing to
3526 %load-extensions' value cell.
3527 (scm_init_load): Initialize it, and the value it points to.
3528 (scm_primitive_load_path): Improve error reporting.
3530 * load.c (scm_loc_load_hook): New variable, pointing to value cell
3531 of new Scheme variable %load-hook.
3532 (scm_primitive_load): Apply %load-hook to filename.
3534 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
3536 * configure.in: add tests for figuring out whether buffered data
3537 is available in a FILE structure, which is needed by char-ready.
3539 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
3542 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
3543 exceptions using misc_error instead of syserror. It seems a bit
3544 odd to throw an exception if a string can't be found in the
3545 environment, but it's consistent with open-file, stat etc.
3546 (simpos.h): remove sys_ from getenv.
3548 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
3549 occurs, throw an error instead of returning errno. Return value
3551 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
3553 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
3555 * filesys.c (scm_stat2scm): derive file type and permissions from
3556 the stat mode and append them to the returned vector.
3557 There isn't much overhead in doing this and it avoids the need to
3558 work with S_IRUSR et al. in Scheme.
3559 Define symbols scm_sym_regular etc.
3560 (scm_init_filesys): don't intern S_IRUSR etc.
3562 * load.c: change s_try_load and s_try_load_path to s_primitive_load
3563 and s_primitive_load_path.
3565 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
3567 * error.h: don't declare error symbols. prototype for scm_misc_error.
3569 * stackchk.c (scm_stack_overflow_key): defined here instead of in
3572 * error.c: use SCM_SYMBOL to set up error keys.
3573 scm_misc_error: new procedure.
3575 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3577 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
3578 between `#!' and `!#' is ignored.
3579 (skip_scsh_block_comment): New function.
3581 * feature.c (scm_set_program_arguments): New argument, FIRST.
3582 * feature.h: Update prototype.
3583 * init.c (scm_boot_guile_1): Pass new argument to
3584 scm_set_program_arguments.
3586 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3588 * init.c (scm_start_stack): Don't initialize scm_progargs here.
3589 (scm_boot_guile): Call scm_set_program_arguments here, later than
3590 the old initialization.
3592 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
3593 initialization procedure.
3594 - Delete in, out, err arguments; there are other perfectly good
3595 ways to override these when desired.
3596 - Delete result argument; this function shouldn't ever return.
3597 - Rename init_func argument to main_func, for less confusion.
3598 - Delete boot_cmd argument; main_func is more general.
3599 -Add 'closure' argument, to help people pass data to main_func
3600 without resorting to global variables.
3601 - Abort if reentered; don't bother returning an error code.
3602 - Call scm_init_standard_ports to set up the default/current
3603 standard ports; no need to pass them to scm_start_stack.
3604 - Remove code to evaluate the boot_cmd, and start the repl; let
3605 the user do something like that in main_func if they want.
3606 - Remove code to package up a return value; main_func can do any
3608 - Call exit (0), instead of returning.
3609 (scm_start_stack): Don't initialize the I/O ports here; that's
3610 weird. Delete in, out, err arguments. Move guts to
3611 scm_init_standard_ports, scm_stdio_to_port.
3612 (scm_init_standard_ports): New function, to set up current and
3613 default standard ports.
3614 (scm_start_stack, scm_restart_stack): Make these static.
3615 * init.h (scm_boot_guile): Adjust declaration.
3616 (scm_start_stack, scm_restart_stack): Remove externally
3617 visible declarations for these.
3618 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
3620 * fports.c (scm_stdio_to_port): New function. Its guts used to be
3621 written out several times in scm_start_stack.
3622 * fports.h: New declaration for the above.
3624 * feature.c (scm_set_program_arguments): New function.
3625 * feature.h: New declaration for the above.
3627 * ports.c: Formatting tweak.
3629 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
3631 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
3632 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
3633 for obtaining the address of a car or cdr field. Motivation:
3634 &SCM_CXR make assumptions about the internal structure of the
3637 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
3638 Motivation: see SCM_CXRLOC.
3640 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
3641 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
3642 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
3643 Motivation: Safer use. Some other macros are defined in terms of
3644 these operations. If these are defined using the SCM_SETCXR
3645 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
3646 to inefficiency and an <e1> with side-effects could potentially
3647 break. Also, these particular operations are heavily utilized in
3648 the garbage collector. In unoptimized code there will be a
3651 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
3652 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
3653 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
3654 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
3655 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
3656 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
3657 vports.c: Cleaned up use of pairs: Don't make any special
3658 assumptions about the internal structure of selectors and
3659 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
3660 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
3661 (Among other things, this change makes it easier to build Guile
3662 with certain compilers which have problems with casted lvalues.)
3664 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3666 * stacks.c: Improve selection of relevant stack frames when making
3667 a stack object. Introduce one level of indirection in the stack
3668 object to make it possible to "narrow" to a certain region of the
3669 stack. This facilitates making use of more clever algorithms (not
3670 implemented) for selecting relevant frames and gives a cleaner
3671 design since selection of frames can be done independently of
3672 extraction of frames from the real stack.
3673 (scm_stack_id): Also take #t as argument which means look at
3676 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
3677 Turn n_tail into an integer directly representing current number
3678 of frames in stack. Add field tail.
3680 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
3682 * debug.c (scm_make_memoized): Made it available at scheme level.
3683 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
3684 SCM_NIMP before applying heavier predicates in argument checking.
3685 (scm_local_eval): Also take memoized object as argument.
3687 * backtrace.c (scm_display_error): Just a safety measure: Stacks
3688 aren't created with zero length, but should such a strange
3689 creature suddenly turn up...
3691 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
3693 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
3694 `del', for the sake of C++ compilers. (Patch applied by JimB.)
3696 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
3698 * variable.c (scm_make_variable): Make the name hint optional, as
3700 (anonymous_variable_sym): Renamed from variable_sym. All uses
3703 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
3704 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
3705 of scm_primitive_load_path was also changed to
3706 "primitive-load-path", from "%try-load-path". Callers changed.
3707 We'd like to respect the convention that a function named
3708 "try-mumble" should behave just like the function called "mumble",
3709 but return #f instead of signalling some error.
3710 * load.h: Rename prototypes.
3712 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3714 * print.c (make_print_state, grow_print_state), print.h: Modified
3715 the print state representation: Don't use a tail array for
3716 recording of circular references. Resizing of the print state
3717 structure invalidates the print state pointer. To avoid passing
3718 around an indirect print state reference to all printing
3719 functions, we instead let the print state reference a resizable
3722 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
3724 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
3725 Don't crash when passed an improper list terminated by a
3726 non-immediate value.
3728 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
3730 Allocate data for structures on an eight-byte boundary, as
3731 required by the tagging system.
3732 * struct.c (alloc_struct): New function.
3733 (scm_make_struct, scm_make_vtable_vtable): Call it.
3734 * struct.h (scm_struct_n_extra_words): Bump to 3.
3735 (scm_struct_i_ptr): New "field".
3736 * gc.c (scm_gc_sweep): When we need to free the data, use the
3737 information stored by alloc_struct to find the beginning of the
3738 block allocated to the structure, so we can free it.
3740 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3742 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
3745 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
3746 (scm_debug_info): New member: id.
3748 * stacks.c: Stacks are now represented as structs; Stacks have an
3749 id given to them by `start-stack'.
3750 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
3752 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
3753 Changed stack representation.
3755 * debug.c (scm_procedure_name): Try procedure property `name' for
3756 compiled closures aswell.
3758 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
3760 * eval.c: scm_i_name moved to gsubr.c
3761 (scm_m_define): Record names of all kinds of procedure
3762 objects. (Earlier, only closures were recorded.)
3764 * procprop.h: Added declaration of scm_i_name.
3766 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
3767 (scm_make_gsubr): Record names of compiled closures.
3769 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3771 * debug.c, debug.h: Removed obsolete code.
3773 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
3774 stacks.c: Renamed regs --> scm_contregs.
3776 * print.c (scm_free_print_state): Cleanup print state before
3777 returning it to pool. It is better to do it here than in
3778 scm_prin1 since scm_prin1 is called often.
3780 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
3781 s_set_source_property_x): Check that first argument is a pair or a
3784 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
3785 scm_i_line, scm_i_column and scm_i_breakpoint global.
3787 * init.c: Added #include "backtrace.h" and #include "stacks.h".
3788 (scm_boot_guile_1): Added calls to scm_init_backtrace and
3791 * debug.h: Added debug object smob declaration and macro
3794 * configure.in: Build with backtrace.o and stacks.o if debug
3797 * Makefile.in: Added entries for new files: backtrace.c,
3798 backtrace.h, stacks.c and stacks.h.
3800 * symbols.c (scm_sym2ovcell): Fixed documentation.
3802 * _scm.h (min, max): Added.
3804 * async.c: Moved `min' macro to _scm.h.
3806 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
3807 SCM_BACKTRACE_INDENT.
3809 * eval.c: Added new debug options `maxdepth' and `indent'.
3811 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
3813 * print.h: Added selector SCM_PRINT_STATE.
3815 * print.c: New functions: scm_make_print_state,
3816 scm_free_print_state.
3818 * print.h: Added declarations for scm_make_print_state,
3819 scm_free_print_state.
3821 * debug.c (scm_m_start_stack): New acro.
3823 * debug.h: Small cleanup.
3825 * init.c (scm_boot_guile_1): Moved scm_init_debug below
3828 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

3849 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
3850 declare functions with prototypes. (Patch thanks to Marius
3853 More prototype-related changes from Marius Vollmer:
3854 * gdb_interface.h: Wrapped header file in #ifdef/#endif
3855 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
3856 * ports.h (ptobfuns): Added prototypes. This means some casting in
3858 * fports.c: Added casts for initializations, since the functions
3859 are defined to take FILE * as their stream argument, not SCM.
3860 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
3861 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
3862 to `char *str_data' to conform to prototype.
3864 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
3866 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
3868 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
3870 * stime.c, stime.h: use SCM_P method.
3872 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
3874 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
3875 be given at least two arguments. Insist that lst's last element
3876 be a list, but don't make any requirements of its predecessors.
3878 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
3880 * eval.c (scm_nconc2last): Revert last change; there seems to be
3881 other stuff going on here.
3883 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
3885 * eval.c (scm_nconc2last): Make sure that each element of lst
3886 (which is a list of argument lists, except for the tail) is a
3887 proper list, i.e., finite and terminated by '().
3889 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
3891 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
3894 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
3895 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
3898 * vectors.c (scm_make_vector): Fill vectors with the undefined
3899 value, to help make Guile Scheme code more portable to other
3902 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
3903 * symbols.h, tags.h: Doc fixes.
3905 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
3907 * async.c (scm_take_signal): Doc fixes.
3909 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
3911 * numbers.c (scm_divbigint): When the remainder is zero, we don't
3912 want to subtract it from the modulus; we just want to leave it
3915 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
3917 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
3920 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
3922 * throw.c (scm_catch_apply): Finished implementation of
3925 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
3927 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
3929 (scm_init_filesys): set "i/o-extensions" feature.
3932 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
3934 * Makefile.in (root.o): Correct dependencies.
3936 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
3938 * Makefile.in: Added dependency entry for root.o.
3940 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
3941 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
3943 * init.c (scm_start_stack): Set initial root continuation number
3946 * procs.c: New function: scm_thunk_p.
3948 * procs.h: Added declarations of scm_thunk_p.
3950 * root.c: Renamed `call-with-new-root' -->
3951 `call-with-dynamic-root'.
3952 (cwdr): Removed allocation of new root state. This should be done
3953 separately by use of scm_make_root.
3954 (scm_apply_with_dynamic_root): New function: Does what it
3955 sounds like. Needed when spawning threads.
3957 * root.h: Added member last_debug_frame to root state.
3958 Added #include "libguile/debug.h"
3960 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
3961 arguments. The motivation is that code in root.c needs catch
3962 functionality, and we want to avoid code duplication.
3963 New functions: scm_catch, scm_lazy_catch. These are wrappers for
3964 scm_catch_apply. scm_lazy_catch is intended to introduce catch
3965 handlers that run without popping the stack into the dynwind
3968 * throw.h: Added prototypes for scm_catch_apply and
3971 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3973 * root.h (scm_root, scm_set_root): Decouple thread support details
3974 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
3975 SCM_SET_THREAD_LOCAL_DATA.
3977 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
3978 and tortoise scanning loop.
3980 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
3982 * Makefile.in: Rebuild dependencies.
3984 * libguile.h: #include "libguile/print.h" before "smob.h", since
3985 the latter uses the print_state structure.
3987 * throw.c (scm_ithrow): Use the correct variable when checking to
3988 see if a given element of scm_dynwinds is a valid catch.
3990 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
3991 structure, abort; don't just silently ignore the garbage.
3993 * _scm.h: #include "print.h" here, since it seems to be used just
3995 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
3996 strports.c, unif.h: Don't #include "print.h".
3998 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4000 * feature.h (scm_loc_features): Removed external declaration.
4001 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4003 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4005 * feature.c (scm_init_feature): Added threads feature (needs to be
4006 initialized here, since features doesn't exist when
4007 scm_init_threads is called).
4009 * libguile.h: Added #include "libguile/../threads/threads.h".
4010 (This is a kludge to get thread support working. This should be
4013 * configure.in, acconfig.h: Added flags for thread support.
4015 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4018 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4019 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4022 * _scm.h: Added conditional #include "threads.h"
4024 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4025 SCM_THREADS_SWITCHING_CODE.
4027 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4028 allocate the basic dynamic root object.
4029 (scm_boot_guile): Added call to scm_init_root.
4031 * root.c, root.h: Added root smob.
4032 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4033 functions: Implements dynamic roots mostly according to spec in
4034 SCM manual. Main difference is that the second argument is a
4035 throw handler rather than an error "thunk".
4037 * root.h: Added declaration of scm_init_root.
4039 * root.c: Added #include "genio.h", #include "smob.h", #include
4040 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4042 (scm_init_root): Added #include "root.x".
4044 * throw.c: Added #include "stackchk.h"
4045 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4046 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4047 can be used in scm_call_with_new_root; Added reenabling of stack
4048 checking when catching a throw.
4050 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4052 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4054 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4055 element is not found, as per R4RS.
4057 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4059 * list.c: Doc fixes throughout.
4061 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4063 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4064 declare the char * to be const. Avoids a warning in rgx.c.
4066 * ports.h: spelling fix.
4068 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4071 * load.c (scm_sys_try_load_path): throw an error if file not found
4072 (like it says it in NEWS).
4074 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4076 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4077 PROPS slot to '(), not #f; it's an empty alist.
4079 * throw.h, throw.c: Use SCM_P instead of #if hair.
4081 Remove special support for uncaught throws; see throw.c for
4083 * throw.c (uncaught_throw): New function.
4084 (scm_ithrow): Call uncaught_throw if we don't find a throw
4085 target; don't mess with scm_bad_throw_vcell.
4086 (scm_bad_throw_vcell): Variable deleted.
4087 (scm_init_throw): Don't initialize it.
4089 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4092 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4094 * numbers.c (scm_istr2int): If the number is short (as most
4095 numbers are), just call scm_small_istr2int to deal with it.
4096 (scm_small_istr2int): New function, created by un-#ifdefing the
4097 non-bignum version of scm_istr2int and renaming it.
4099 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4101 * load.c (scm_sys_try_load): don't check whether value returned
4102 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4103 Change the Scheme name from %try-load to primitive-load.
4105 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4106 Can avoid passing a message, allowing it to be derived in the
4107 error handler (e.g., if we want to throw to the key both from
4110 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4112 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4113 references now have a new appearance which is more compact and
4114 also gives a clue about what the target of the reference is.
4115 By setting parameters in the print state, more fancy printing can
4116 be achieved. This is used by the (not yet commited) backtrace
4119 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4121 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4124 * print.c: Added #include "struct.h". Removed function
4127 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4128 scm_iprin1. Removed prototype for scm_prlist.
4130 * arbiters.c (prinarb),
4131 async.c (print_async),
4132 debug.c (prindebugobj, prinmemoized),
4133 eval.c (prinprom, prinmacro),
4134 filesys.c (scm_fd_print, scm_dir_print),
4136 mallocs.c (prinmalloc),
4137 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4138 smob.h (scm_smobfuns),
4139 srcprop.c (prinsrcprops),
4141 unif.c, unif.h (scm_raprin1, rapr1),
4142 variable.c (prin_var): Changed argument `int writing' to
4143 `scm_print_state *pstate'.
4145 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4146 that it will be called before scm_init_print.
4148 * print.c (scm_prin1): Print states are now allocated when calling
4149 scm_prin1 and then passed around to all printing functions as an
4150 argument. A cache `print_state_pool' enables reuse of print
4152 (scm_make_print_state): New function.
4153 (scm_iprin1): Adaption to print states.
4154 (scm_iprlist): An initial "hare and tortoise" scan brings down
4155 time complexity to O (depth * N). (Better time complexity will be
4156 achieved when the printing code is completely rewritten.)
4158 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4160 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4161 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4162 it gets done whether or not the cache variable has a value.
4164 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4166 Distinguish #f and ().
4167 * __scm.h: #undef SICP.
4168 * pairs.h (SCM_EOL): Delete this definition, equating it with
4170 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4171 the value it used to have. Doc fixes, too.
4173 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4175 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4176 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4177 Lord's implementation of structs, allowing for tail arrays as
4178 described in the manual. Also fixed some bugs. (Both the interface
4179 and the implementation should be improved.)
4181 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4183 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4184 People who whish to see the source can do `(print-enable 'source)'.
4185 Removed #ifdef DEBUG_EXTENSIONS.
4187 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4189 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4190 integer (assuming for now accepting an integer is a good thing).
4192 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4193 %S will be used instead for write'ing arguments.
4195 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4196 asserts. fix a few other asserts.
4197 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4198 scm_uniform_vector_ref, scm_array_set_x,
4199 scm_dimensions_to_unform_array): change args in
4200 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4201 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4202 scm_substring_fill_x): likewise.
4203 gsubr.c (scm_gsubr_apply): likewise.
4204 eval.c (SCM_APPLY): likewise.
4206 * eval.c (4 places): replace scm_everr with lgh_error or
4209 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4210 scm_memory_error): new procedures.
4211 scm_everr: deleted. can use scm_wta, dropping first two args.
4212 scm_error: convert NULL subr to SCM_BOOL_F.
4214 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4217 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4220 * error.c, error.h: new error keys: scm_arg_type_key,
4221 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4223 scm_wta: reimplement using lgh_error instead of scm_everr.
4225 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4227 * gdbint.c: scm_lread now has one more argument.
4229 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4230 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4231 loading source from non-file ports, which, e. g., happens when
4232 using the Emacs interface).
4234 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4237 * read.c: Added code for recording of positions of source code
4238 expressions; New functions: recsexpr, scm_lreadrecparen;
4239 _scm_make_srcprops --> scm_make_srcprops
4240 (scm_flush_ws): Removed updating of positions counters. This work
4241 is already done by scm_gen_getc
4243 * read.h: Added prototype for scm_lreadrecparen
4245 * print.c: Added #include "alist.h"
4247 * eval.c: Added #include "hash.h"
4249 * eq.c: Added #include "ramap.h"
4251 * options.c: Documentation fixes.
4253 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
4254 (scm_init_srcprop): Adjusted size of initial source-whash. Name
4255 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
4256 --> scm_make_srcprops
4258 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
4259 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
4260 function calls in the definition of the whash access macros.
4262 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
4264 * init.c (scm_boot_guile): Add level of indirection to
4265 scm_boot_guile_1() to ensure that stack base pointer is properly
4266 initialized. There was no guarantee that variable i was the
4267 highest/lowest variable on stack (i.e. the call frame of
4268 scm_boot_guile was not completely protected from gc).
4270 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
4272 * ports.h (scm_port_table): put back file_name, it will be used to
4273 support debugging. Undo related changes in fports.c, ioext.c,
4276 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4278 * ports.h (scm_port_table): remove file_name member for now, it seems
4280 * fports.c (scm_open_file): don't set file_name in PTAB.
4281 (prinfport): don't use file_name in PTAB.
4282 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
4283 * ports.c (scm_add_to_port_table): don't intialize file_name.
4284 (scm_port_file_name): remove for now.
4285 * gc.c (scm_gc_mark): don't mark PTAB file_name.
4287 * fports.h (scm_mkfile): prototype deleted.
4288 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
4290 * debug.c, unif.c: use scm_out_of_range instead of
4291 wta for range errors (ASSERT still needs work).
4293 * error.c, error.h (scm_out_of_range): new procedure.
4295 * error.c, error.h (scm_out_of_range_key): new key.
4297 * posix.c (scm_sync): #else was missing.
4299 * error.c, error.h: append _key to names scm_num_overflow and
4302 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
4303 of consing an empty list.
4304 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
4305 of macros, saves code and string space.
4306 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
4307 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
4308 lower case. Rename scm_syserror_m to scm_syserror_msg.
4309 error.h: prototypes for new procedures.
4311 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
4313 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
4315 * error.c, error.h: setup scm_num_overflow key.
4317 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
4318 Remove definition of SCM_OVSCM_FLOW.
4320 * fports.c (scm_open_file): use SCM_SYSERROR_M.
4322 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
4323 explicit message and args.
4325 * error.c, error.h, __scm.h: change system_error_sym to
4328 * error.c (system_error_sym): remove leading %% from the Scheme name
4331 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
4333 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4335 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
4336 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
4337 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
4338 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
4339 renamed. (These were introduced by unsupervised name
4342 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4344 * print.c: Added code for detection of circular references during
4345 printing. (init_ref_stack, grow_ref_stack): New functions. Added
4346 a hook for printing of closures (accessible via print options).
4347 This leads to a split of calls to scm_iprin1 into two classes:
4348 elementary print operations (e. g. the code which prints a smob)
4349 still use scm_iprin1 while top level calls (like scm_display) use
4350 scm_prin1. scm_prin1 begins by clearing the data structure used
4351 to record reference information.
4353 * print.h: Added declarations of scm_prin1 and scm_prlist.
4355 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
4357 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
4359 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
4361 * error.c (err_head): scm_iprin1 --> scm_prin1
4363 * debug.c: Adjusted header comment.
4367 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4369 * strerror.c: Doc fix.
4371 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4373 * gdbint.c (gdb_read): Now possible to run during GC.
4374 (unmark_port, remark_port): New functions.
4376 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
4378 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
4379 of allocating a new string object. Also, increase size by
4380 the factor 2 instead of 1.5.
4382 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
4384 * __scm.h (SCM_P): Corrected to run under traditional C.
4386 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
4389 * async.c: Calls to scm_sysintern corrected.
4391 * async.h (scm_async_clock): Redundant declaration removed.
4393 * continuations.c (scm_dynthrow): Redundant declaration removed.
4395 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
4396 Definition typos corrected.
4398 * debug.h: Missing declarations of functions in debug.c added
4401 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
4402 Missing declarations to functions in eval.c added.
4404 * filesys.c: Possibly uninitialized variable rv.
4406 * gc.h (scm_object_addr, scm_unhash_name): Missing
4407 declarations of functions defined in gc.c added.
4409 * genio.c: Possible typos str_data -> wstr_data. ???
4411 * genio.c: Possibly unintended shadowing of local variable
4412 `int c' (gotos out of scope of inner `c'). ???
4414 * init.c: Uninitialized `SCM last' may be used.
4416 * ioext.h: (scm_sys_isatty_p): Typo.
4418 * list.h (scm_list_head): Missing prototype for function in
4421 * numbers.c (scm_two_doubles): Changed from extern to static
4422 (is used only within numbers.c).
4424 * numbers.h: Repeated declarations removed.
4426 * ports.h (scm_close_all_ports_except): Declaration for the
4427 function defined in ports.c added.
4429 * posix.h: Missing declarations added.
4431 * procs.h (scm_make_subr_opt): Missing declaration added.
4433 * socket.h (scm_sys_gethost): Missing declaration added.
4435 * socket.h: Redundant declarations removed (they are in fdsocket.h).
4437 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
4438 Missing declarations added.
4440 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
4442 * struct.c: Uninitialized variable `SCM answer' may be used.
4444 * unif.c (l2ra): Declaration prototype.
4446 * unif.c (scm_array_equal_p): Dummy definition removed (it is
4447 defined in ramap.c).
4449 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
4450 Redundant declarations removed (they are in ramap.h).
4452 * variable.h (scm_make_udvariable,
4453 scm_make_undefined_variable): Declaration corrected to
4454 correspond variable.c.
4456 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
4457 Missing declarations added.
4459 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
4461 * Makefile.in (distclean): Don't forget to delete fd.h.
4463 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4465 * fd.h.in, tags.h: Trivial cleanups.
4467 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
4468 marksweep.h just declared functions from gc.c.
4469 * gc.h, libguile.h: Don't #include "marksweep.h".
4470 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4471 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
4472 dependencies updated.
4474 * libguile.h: Don't #include "files.h"; it's been deleted.
4476 * files.c (scm_sys_delete_file): Moved to filesys.c.
4477 File is now empty; deleted.
4479 * filesys.c: scm_sys_delete_file is now here. Remove
4480 #if's; they seem to rely on remnants of an old portability
4481 regimen. If the problems come up again, solve them properly,
4482 using autoconf. Specifically: Don't test M_SYSV, and #define
4483 remove to be unlink if it's #defined; don't use remove just
4484 because HAVE_STDC_HEADERS is #defined.
4485 * filesys.h: Add declarations for scm_sys_delete_file.
4486 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4487 files.o, files.h, files.c, and files.x.
4488 * init.c: Don't #include "files.h", and don't call scm_init_files.
4490 Use SCM_P instead of PROTO; the latter intrudes on the user's
4492 * params.h: Deleted; definition of SCM_P moved to...
4493 * __scm.h: ... here, where it replaces PROTO macro.
4494 * libguile.h, smob.h: Don't #include "params.h".
4495 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
4496 smob.h: Fix prototypes accordingly.
4497 * Makefile.in: Update dependencies.
4498 (inner_h_files): Remove params.h.
4500 * gc.c: #include "gc.h"; every module should include its header,
4501 to let the compiler cross-check the declarations against the
4504 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
4505 simpos.h: #include "libguile/__scm.h".
4507 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
4509 * init.c: Don't forget to #include smob.h and init.h.
4510 * Makefile.in: Dependencies updated.
4512 * smob.h: Use PROTO instead of #if __STDC__.
4514 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
4516 * __scm.h: Doc fixes.
4518 * __scm.h, libguile.h: Use "quotes" in the #includes, not
4519 <angles>; this allows `make depends' to work properly.
4521 * libguile.h: #include smob.h and pairs.h before the others; they
4522 define typedefs used by other headers.
4524 C files should #include only the header files they need, not
4525 libguile.h (which #includes all the header files); the pointless
4526 recompilation was wasting my time.
4527 * Makefile.in (all .o dependency lists): Regenerated.
4528 * libguile.h: Don't try to get a definition for size_t here...
4529 * __scm.h: Do it here.
4530 * _scm.h: Since this is the internal libguile header, put things
4531 here that all (or a majority) of the libguile files will want.
4532 Don't #include <libguile.h> here; that generates dependencies on
4533 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
4534 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
4535 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

4632 * weaks.c: Get "weaks.h".
4634 * stackchk.h: #include "libguile/debug.h",
4636 * print.h, read.h: #include "options.h", since everyone who uses
4637 either of these files will need that.
4639 * smob.h: #include "ports.h", "genio.h", and "print.h", since
4640 anyone who uses this file will need them to define the smob
4641 printing functions. Also, get markers.h, since people will need
4642 to #define the mark functions.
4644 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
4645 * ports.h: ... to here.
4647 * ports.h (scm_port_table_size): Explicitly give type as 'int';
4648 don't rely on archaic C default type rules.
4650 * fports.h: #include "libguile/ports.h", since you need that in
4651 order to parse this.
4653 * genio.h: #include "libguile/print.h", because you need that to
4654 parse this; don't bother #including "ports.h", since print.h gets
4657 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
4659 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
4660 this; it's now a reference to an element of *scm_root.
4662 * debug.h: Don't #include "options.h"; the compiler won't be able
4663 to find that once the headers are installed; instead, #include
4664 "libguile/options.h".
4665 * gc.h: Same, with marksweep.h.
4666 * mbstrings.h: Same, with symbols.h.
4667 * scmhob.h: Same, with _scm.h.
4668 * smob.h: Same, with params.h.
4670 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
4671 C files; there's no need for this, and it forces recompilations
4674 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
4676 * error.c (scm_error): declare scm_error_callback.
4678 * error.h: prototype for scm_error_callback.
4680 * __scm.h: define lgh_error.
4681 (SCM_SYSERROR): redefine using lgh_error.
4683 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
4685 * error.c (scm_error): new procedure.
4687 * error.h: prototype for scm_error.
4689 * Makefile.in (install): install scmconfig.h from the current
4690 directory, not $(srcdir).
4692 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
4694 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
4695 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
4696 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
4697 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,

4701 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
4702 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
4703 vports.h, weaks.h: #include "libguile/__scm.h", not
4704 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
4705 dependencies are within libguile properly.
4707 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
4709 * Makefile.in (.c.x): Simplify; there's no need to run this rule
4710 when scmconfig.h doesn't exist.
4712 * load.c (scm_sys_try_load): Correct spelling.
4714 * feature.c (scm_loc_features): Make this static.
4716 * Makefile.in (libpath.h): Omit trailing slash from path. We
4717 shouldn't require it of users, so why put it here?
4719 Move code to initialize and search %load-path from ice-9 to C
4720 code, so we can use the load-path to find the ice-9 boot code;
4721 this makes it easier to run Guile without installing it. See
4722 corresponding changes in guile/Makefile.in.
4723 * feature.c: Move stuff concerned with the load path to load.c.
4724 (scm_compiled_library_path): Deleted.
4725 Don't #include libpath.h here.
4726 * feature.h: Don't mention scm_compiled_library_path.
4727 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
4728 <sys/stat.h>, and <unistd.h> (if present).
4729 (R_OK): #define if the system hasn't deigned to.
4730 (scm_loc_load_path): New variable.
4731 (scm_init_load_path, scm_sys_search_load_path,
4732 scm_sys_try_load_path): New functions.
4733 (scm_init_load): Initialize scm_loc_load_path to point to the
4734 value cell of the Scheme %load-path variable.
4735 * load.h: Add declarations for scm_sys_search_load_path,
4736 scm_sys_try_load_path.
4737 * init.c: Call scm_init_load_path.
4738 * Makefile.in (feature.o, load.o): Dependencies updated.
4740 * load.c, load.h: Rewrite using PROTO macro.
4742 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4744 * gc.c (scm_cellp): New function: C predicate to determine if an
4745 SCM value can be regarded as a pointer to a cell on the heap.
4747 * gc.h: Added declaration of scm_cellp.
4749 * gdb_interface.h: New file: The GDB interface header from the GDB
4752 * gdbint.c: New file: GDB interface.
4754 * gdbint.h: New file: GDB interface.
4756 * libguile.h: Added #include <libguile/gdbint.h>.
4758 * init.c (scm_boot_guile): Added scm_init_gdbint.
4760 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
4761 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
4762 found if object files and source are kept separate).
4764 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
4766 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
4768 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
4770 * configure.in: Don't substitute the values of TCL_SRC_DIR and
4771 TK_SRC_DIR; they're not relevant any more.
4773 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
4774 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
4776 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
4778 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
4779 search path, so we can find the <libguile/MUMBLE.h> headers.
4781 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
4783 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
4784 implicit in the .c.o rule.
4785 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
4788 Put the library path in a header file, instead of passing it on
4789 the command line in every compilation.
4790 * Makefile.in (libpath.h): New target.
4791 (feature.o): Depend on libpath.h.
4792 (clean): Delete libpath.h.
4793 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
4794 * feature.c: ... #include "libpath.h" here.
4795 * .cvsignore: Ignore libpath.h.
4797 Don't install the unwashed masses of Guile header files in the
4798 main #include path; put most of them in a subdirectory called
4799 'libguile'. This avoids naming conflicts between Guile header
4800 files and system header files (of which there were a few).
4801 * Makefile.in (pkgincludedir): Deleted.
4802 (innerincludedir): New variable; this and $(includedir) are enough.
4803 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
4804 (installed_h_files): Divide this up. Now this variable lists
4805 those header files which should go into $(includedir) (i.e. appear
4806 directly in the #include path), and ...
4807 (inner_h_files): ... this new variable says which files appear in
4808 a subdirectory, and are referred to as <libguile/mumble.h>.
4809 (h_files): List them both.
4810 (install): Create innerincludedir, not pkgincludedir. Put
4811 the installed_h_files and inner_h_files in their proper places.
4812 (uninstall): Corresponding changes.
4813 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
4814 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
4815 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
4816 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
4817 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
4818 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
4819 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
4820 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
4821 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
4822 vports.h, weaks.h: Find __scm.h in its new location.
4823 * __scm.h: Find scmconfig.h and tags.h in their new locations
4824 (they're both "inner" files).
4826 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
4828 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
4830 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4832 * posix.c: Doc fixes.
4834 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
4836 * socket.c: Don't include a prototype for inet_aton; just use a
4837 K&R style declaration, to avoid warnings but minimize the chance
4838 of conflicts with the system.
4840 On NextStep, <utime.h> doesn't define struct utime, unless we
4841 #define _POSIX_SOURCE before #including it.
4842 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
4843 * acconfig.h: New comment text for above CPP symbol.
4844 * configure.in: Call it.
4845 * posix.c: #define _POSIX_SOURCE if it seems necessary.
4847 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
4849 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
4850 testing for __EMX__.
4852 * posix.c: #include <libc.h>, if it exists.
4854 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
4855 don't even know if the latter exists.
4857 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
4858 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
4859 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
4861 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
4863 (scm_init_posix): Use them when initializing the Scheme constants
4866 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4868 * Makefile.in (libdir, includedir, bindir): Use the
4869 autoconf-supplied values, instead of deriving them ourselves.
4870 (pkgincludedir, datadir, pkgdatadir): New variables.
4871 (install, uninstall): Put the header files in a special
4872 subdirectory, not in the main search path.
4874 * Makefile.in (ALL_CFLAGS): Provide the proper value for
4875 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
4877 * Makefile.in (IMPLPATH): Deleted; never used.
4879 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
4880 on the Tcl/Tk source any more.
4881 (INCLUDE_CFLAGS): Remove references to the above.
4883 * Makefile.in (version.o): Corrected dependencies.
4885 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
4887 * libguile.h: #include "version.h"
4889 * init.c (scm_boot_guile): Call scm_init_version.
4890 * gscm.c (gscm_run_scm): Call scm_init_version.
4892 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
4893 GUILE_VERSION): AC_DEFINE these.
4894 (acconfig.h): #undef the above symbols.
4896 * Makefile.in (libobjs): Add version.o.
4897 (installed_h_files): Add version.h.
4898 (c_files): Add version.c.
4899 (gen_c_files): Add version.x.
4900 (version.o): New rule.
4901 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
4902 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
4903 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
4904 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
4905 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
4906 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
4907 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
4908 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
4909 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
4910 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
4911 weaks.o): Add version.h to dependency lists.
4912 (markers.o): Remove duplicate rule.
4914 * version.h: New file.
4916 * version.c: New file.
4918 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4920 * symbols.c (scm_strhash): scm_downcase is now a function, not an
4921 array; use it appropriately. Since GCC is quite happy to
4922 subscript functions, it never warned us about this; we should use
4923 -Wpointer-arith in the future. I guess we never tested
4926 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
4928 * socket.c: Doc and copyright fixes.
4930 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4932 * debug.c: Fixed and improved gdb support.
4934 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4936 * socket.c: Added declaration of inet_aton to avoid compiler
4937 warning. (Hope this solution is correct.)
4939 * stime.c: Added declaration of ftime. (This is missing in
4942 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
4944 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
4946 * Makefile.in (c_files): add strerror.c.
4948 * strerror.c: new file from Emacs' sysdep.c.
4949 maybe configure should also check for sys_errlist.
4951 * configure.in (AC_REPLACE_FUNCS): add strerror.
4953 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4955 * debug.c (scm_init_debug): Added initialization for
4956 scm_evaluator_traps.
4958 * debug.h, debug.c: Various name changes.
4959 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
4960 "debug-options-interface". See commentary in options.c.
4962 * options.h, options.c: Options now have documentation strings.
4963 Also added a long explanatory commentary.
4965 * eval.c, print.h, print.c, read.h, read.c: Modifications to
4968 * gscm.c, init.c, root.c, throw.c: Bug fixes:
4969 last_debug_info_frame is now updated in all cases.
4971 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
4974 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4976 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
4977 Added option STACK_CHECKING.
4979 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4981 * Makefile.in: Added {debug,options,srcprop}.{h,c}
4983 * __scm.h: Removed symbols for debugging support.
4985 * acconfig.h: Added symbols for debugging support.
4987 * configure.in: Added user option for debugging support.
4988 --enable-debug will include the debugging code into libguile.a.
4990 * continuations.c (scm_make_cont): Enlarged the #if 0 around
4991 scm_relocate_chunk_to_heap.
4993 * debug.c: New file: low-level debugging support. It also
4994 includes support for debugging with gdb. (The extensions to gdb
4995 are written by Per Bothner at Cygnus.)
4997 * debug.h: New file: low-level debugging support.
4999 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5000 argument pairs. Extensive modifications to the debugging
5001 evaluator. Added "SECTION:" commentaries to clarify what happens
5002 when, during double compilation. Renamed EVALIMP --> EVALIM.
5003 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5004 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5005 the beginning of the file. New procedure: scm_unmemocopy.
5006 Added some global state variables needed by the debugging
5007 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5008 check_entry, check_apply, check_exit, debug_options and
5009 evaluator_traps. New acro: undefine.
5011 * eval.h: Renamed EVAL --> XEVAL.
5013 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5014 --> scm_make_weak_key_hash_table.
5016 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5017 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5019 * libguile.h: Conditionally include debug.h
5021 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5022 scm_object_properties shouldn't return handle. `handle' now gets
5023 initialized in scm_set_object_properties_x. scm_object_properties
5024 doesn't any longer create an entry in scm_object_whash.
5026 * options.c: New file: handling of run time options.
5028 * options.h: New file: handling of run time options.
5030 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5032 * print.c: New procedure: scm_print_options
5034 * print.h: Defines for print options.
5036 * read.c: New procedure: scm_read_options
5038 * read.h: Defines for reader options.
5040 * root.h: Added scm_source_whash among scm_sys_protects.
5042 * srcprop.c: New file: source properties.
5044 * srcprop.h: New file: source properties.
5046 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5047 (Bug found by A. Green.)
5049 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5051 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5053 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5055 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5057 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5058 and should be called by the final client.
5060 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5062 * gc.h: Use the PROTO macro when declaring functions.
5063 * gc.c: Use the PROTO macro when declaring static functions.
5064 Remove the CPP hair around function definitions.
5066 * gc.c (scm_init_storage): Initialize scm_asyncs.
5068 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5069 preprocessor symbol; "__scm.h" is where it might get #defined.
5070 * __scm.h: Similar: #include <scmconfig.h> before testing
5073 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5075 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5077 * init.c (scm_boot_guile): Add init_func argument; call
5078 (*init_func) instead of calling scm_appinit; it's ucky to
5079 hard-code names for the user's procedures.
5080 * init.h (scm_boot_guile): Adjust declaration.
5082 * __scm.h (PROTO): New macro, for declaring functions with
5085 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5086 eliminate all the __STDC__ conditionals.
5087 (scm_boot_guile): Add declaration.
5088 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5089 Remove __STDC__ conditionals around function definitions; the
5090 declarations in init.h will provide the same information, more
5093 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5094 complain about it in the error message; the error message is
5095 adequate without that note, and there's nothing the user can do
5098 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5100 * Makefile.in (ancillary): Drop def.sed.
5102 * posix.c (scm_init_posix): Use numeric values, rather than
5103 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5104 F_OK. The symbols aren't available on some systems, and I'm
5105 pretty sure their values are fixed by common widespread practice.
5106 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5108 More functions unavailable on some systems.
5109 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5110 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5112 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5113 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5114 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5115 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5116 stub that signals an error as the #else.
5118 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
5120 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
5122 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
5124 * unif.c: include ramap.h.
5126 * read.c (endif): case_insensative_p renamed case_insensitive_p.
5128 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
5130 * ports.c: include sys/ioctl.h.
5132 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
5134 * configure.in: check for sys/ioctl.h.
5136 * ports.c: include <malloc.h> not "malloc.h".
5138 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5140 * fports.c: remove ttyname and tmpnam declarations.
5142 * posix.c: fewer ttyname declarations.
5144 * fports.c: include <string.h> not "string.h".
5146 * init.c, ioext.c: include string.h and unistd.h.
5148 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5150 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
5151 genio.c, simpos.c, vports.c: include string.h.
5153 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
5155 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
5157 (scm_addr_buffer_size): change type from scm_sizet to int.
5158 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
5159 from scm_sizet to int.
5161 * error.c: include unistd.h.
5163 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
5166 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
5168 * __scm.hd, def.sed: deleted.
5170 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
5172 Changes for NeXT, suggested by Robert Brown.
5173 * configure.in: Call AC_TYPE_MODE_T.
5174 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
5175 NeXT. Put header file list in alphabetical order.
5176 * configure, scmconfig.h.in: Regenerated.
5177 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
5179 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
5182 * acconfig.h: New file, providing documentation for the CPP
5183 symbols defined in configure.in
5184 * acconfig-1.5.h: Removed; superceded by the above.
5186 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
5188 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
5190 * fports.c (scm_open_file): don't return #f, throw error.
5192 * ioext.c (fileno): renamed from %fileno.
5193 (soft-fileno): deleted.
5195 * ports.c (scm_port_revealed): don't need to check for -1 from
5197 (scm_set_port_revealed_x): return unspecified, not #f.
5199 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
5201 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
5203 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
5205 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
5207 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5209 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5210 This is necessary on Ultrix, and doesn't hurt portability.
5212 * Makefile.in (dist-dir): New target, implementing a new dist system.
5213 (installed_h_files): Put in alphabetical order.
5214 Remove duplicate entries for markers.h and unif.h.
5215 (c_files): Remove duplicate entries for markers.c.
5216 (ancillary): Renamed from anillery; all uses changed. Remove
5217 PLUGIN; it's a directory, and needs special treatment in dist-dir.
5218 Remove all the ../doc/* files; doc/Makefile.in handles that.
5220 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5222 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5223 every if must have an else, or else the whole command has a
5224 non-zero exit code whenever the if's condition is false.
5226 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
5228 * posix.c: include string.h.
5230 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
5232 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
5235 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
5236 Remove leading % from scheme names.
5237 Do not return error values, call SCM_SYSERROR or similar.
5239 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
5241 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
5243 * struct.c (scm_init_struct): new file.
5245 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
5247 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
5248 (scm_list_head): added list-head for rapidly chopping argument
5249 lists off of longer lists (and similar).
5251 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
5253 * objprop.c (scm_object_property): assq the cdr of the whash
5254 handle for obj, not the handle itself.
5256 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
5258 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
5259 weak hash tables last of all marking to avoid an obscure gc bug.
5260 WARNING: circular lists stored in a weak hash table will hose us.
5262 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
5264 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
5265 new functions similar to scm_substring_move_left_x and
5266 scm_substring_move_right_x.
5268 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
5270 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
5273 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
5275 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
5277 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
5279 * strports.c (scm_strprint_obj): convenience function. C for
5280 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
5282 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
5283 removed to a separate library
5285 * init.c (scm_boot_guile): copied from guile-tcl.c.
5286 Initialization specific to tcl interpreters removed.
5288 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
5290 * ports.c (scm_ports_prehistory): size malloced here doesn't
5291 matter so long as it is non-0 (got rid of "* 4").
5293 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
5295 * gscm.h: gscm_mkarray eliminated (presumably was not being used

5300 * mallocs.[ch]: back again (for rx at least).
5302 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
5304 * ports.c: removed functions relating to the mapping between ports
5305 and descriptors. (That stuff is unix-specific and should be collected

5313 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
5314 handled correctly (SCM_FREEP was applied to them) -- test for
5315 NIMP. Keys in weak hash tables were spuriously (though harmlessly)

5370 * ports.c (scm_add_to_port_table): Added fields
5371 to port table entries: file_name, line_num, col.

5483 initialization to fix a race condition.
5485 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

5509 set the multi_byte flag correctly in symbols. This is wrong.
5510 intern_obbary_soft and msymbolize should take an extra parameter.
5511 Also, weird multibyte symbols don't print correctly.
5512 The weird symbol syntax is also a bit bogus (emacs doesn't quite
