1 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
3 * Makefile.in: Regenerated using the last public version of
4 automake, not the hacked Cygnus version.
6 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
9 * Makefile.in, scmconfig.h.in: Regenerated.
10 * init.c, readline.c: Don't check if TOTORO is #defined.
12 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
14 * Makefile.am: Adjust for new thread configuration system.
15 (INCLUDES): Include the value of THREAD_CPPFLAGS.
16 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
18 (THREAD_LIBS): Definition deleted; automake will generate such
20 * Makefile.in: Regenerated.
22 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
24 Simplify smob and port marking; set the mark bit in the generic
25 marking code, and make marker routines only responsible for
26 turning up outgoing pointers.
27 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
28 before calling the marking function. Don't call the marking
29 function if it's zero.
30 * markers.c (scm_mark0): Just return #f. This function isn't
31 necessary at all now, but it's harmless to call it. We'll leave
32 it in so other folks' code doesn't croak at link time.
33 (scm_markcdr): Don't call SCM_SETGC8MARK.
34 * async.c (mark_async): Don't call SCM_SETGC8MARK.
35 * dynl.c (mark_dynl_obj): Same.
36 * root.c (mark_root): Same.
37 * srcprop.c (marksrcprops): Same.
38 * unif.c (markra): Same.
39 * variable.c (scm_markvar): Same.
40 * ports.c (scm_markstream): Same.
41 (void_port_ptob): Specify zero for our marking function.
42 * debug.c (debugobjsmob): Same.
43 * dynwind.c (guardsmob): Same.
44 * filesys.c (dir_smob): Same.
45 * fluids.c (fluid_smob): Same.
46 * fports.c (scm_fptob, scm_pipob): Same.
47 * mallocs.c (mallocsmob): Same.
48 * regex-posix.c (regex_t_smob): Same.
49 * smob.c (freecell, flob, bigob): Same.
50 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
51 * throw.c (jbsmob, lazy_catch_funs): Same.
53 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
55 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
56 scm_copy_tree on code in order not to let memoized code to leak
57 out. Thus, scm_copy_tree needs to copy vectors as well since
58 quasiquote can introduce evaluated code also inside vector
61 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
63 * eval.c (scm_copy_tree): Removed ability to copy vectors.
65 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
66 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
69 * unif.c: Say that ivect and uvect are of type signed and unsigned
70 long instead of int in commentary so that it correctly describes
73 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
75 * stime.c: Removed declaration of strptime. (It should be
76 declared by the system headers. If it turns out that some systems
77 don't, we'll handle that then.) (Thanks to Greg Troxel.)
79 * stime.h: Renamed TIMEH --> STIMEH
81 * backtrace.c (scm_display_error, scm_display_backtrace): In order
82 to increase portability, don't use structure assignment.
83 (Thanks to Nicolas Neuss.)
85 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
87 (finalize_fd_sets): Added empty statement after last case label.
88 (Thanks to Nicolas Neuss.)
90 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
93 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
95 * init.c, readline.c: OK, I won't have these readline.x bug
96 reports anymore. We've had them since April. The current reason
97 is a completely unintelligible failure of totoro.red-bean.com to
98 do the test for rl_getc_function in libreadline correctly. This
99 kludge overrides the test if we're on totoro so that the snapshot
100 generation process can work.
102 * readline.c: Define a strdup replacement if not existent on system.
104 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
106 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
107 This change makes scm_make_vector R5RS compatible. We cannot keep
108 the third argument since people want to be able to deduce the form
109 of the C function call only by looking at R5RS. (At the same time
110 we have removed some unnecessary complexity!)
112 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
113 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
114 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
115 argument in call to scm_make_vector.
117 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
119 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
120 This macro is useful in applications.
122 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
124 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
125 (scm_parse_path, scm_search_path): New Scheme level procedures.
127 * load.h (scm_internal_parse_path, scm_parse_path,
128 scm_search_path): Declared.
130 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
132 * filesys.c (dirname, basename): New procedures.
134 * init.c (scm_boot_guile_1): Removed condition around
137 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
138 new data type (guards) for representation of C level guards and
139 data on the wind chain.
140 (scm_internal_dynamic_wind): New function.
142 * dynwind.h: Declare scm_internal_dynamic_wind.
144 * root.h (scm_root_state): Added scm_cur_loadp.
146 * root.c (mark_root): Added comment about cur_loadp.
148 * load.c: #include "dynwind.h";
149 (scm_primitive_load): Use scm_inner_dynamic_wind to update
152 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
154 * ports.c (current-load-port): New procedure.
156 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
158 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
159 not a tty, return #f.
161 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
162 to Julian Satchell and Roland Kaufmann.)
164 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
165 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
167 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
169 * debug.h, debug.c (scm_start_stack): New function. Implements
170 the guts of old scm_m_start_stack.
172 * debug.c (scm_m_start_stack): Use scm_start_stack.
174 * init.c (scm_start_stack, scm_restart_stack): Renamed to
175 start_stack and restart_stack. (These have static scope.)
177 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
179 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
180 readline functions to come in release 2.3. (Thanks to Chet
182 (handle_errors): Use the above functions.
184 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
186 * readline.c: Improvements for readline support: Handle errors
187 better; Implement before-read-hook.
189 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
191 * init.c (scm_boot_guile_1), readline.c: Test for
192 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
193 assure that we have version >= 2.1.)
195 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
197 * readline.c (scm_add_history): Bugfix: Do strdup before giving
198 away the string to add_history.
199 (completion_function): Do completion for readline. (Thanks to
201 (scm_filename_completion_function): New procedure: Filename
203 (current_input_getc): New function. Use this one instead of
204 standard getc from readline.
206 * throw.c, throw.h (scm_handle_by_throw): New function: This
207 handler throws errors to next handler on the dynwind chain.
209 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
211 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
214 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
216 * procprop.c (scm_i_procedure_arity): New function. Returns arity
218 (scm_procedure_properties): Modified to return arity together with
220 (scm_procedure_property): Added the read-only property `arity'.
221 (scm_set_procedure_property_x): It is an error to set the `arity'
224 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
225 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
227 * procprop.h (scm_sym_arity): New symbol.
229 * objects.c (scm_set_object_procedure_x): New procedure: Use this
230 to set the dispatch procedure of an operator or entity object.
232 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
233 Made procedure slots read-only.
235 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
236 scm_tcs_cons_gloc case in zero args switch; Fixed args
237 construction for operators in scm_tcs_cons_gloc case in two args
240 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
242 * fluids.c: Removed use of assert.h (in order to avoid
245 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
247 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
249 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
250 change makes the evaluator safer at the cost of evaluation speed.
251 It handles the case when the user has added a non-immediate
252 improper end of the application form, e.g., `(+ 0 . x)'.
253 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
254 minimize the extra cost as much as possible. The new code is
255 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
256 problem with structs planted directly in the code (e.g. by a
257 macro). This no longer causes segmentation fault. (Thanks to
260 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
261 arg `proc' in order to be able to throw errors; New argument
264 * Removed extra #include "debug.h"
266 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
268 * scmsigs.c: Declare usleep as returning void on some systems.
269 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
272 * coop.c (usleep): Return void on some systems.
274 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
276 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
278 * coop.c: Changed return type of usleep to int.
280 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
281 isn't found in the OS.
283 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
284 isn't enabled. (Thought that I had made this change ages ago...)
286 * iselect.c: Declare bzero if not defined by OS.
288 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
290 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
291 condition. (Thanks to John Tobey.)
293 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
294 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
297 * __scm.h: Start the long-term project of moving to POSIX threads.
298 Phase 1: Classification of all critical sections.
299 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
300 for A sections. (See comments in __scm.h for details.)
302 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
303 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
305 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
307 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
308 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
309 (libpath.h, versiondat.h): Replaced dependency on Makefile with
310 dependencies on $(srcdir)/Makefile.in
311 $(top_builddir)/config.status in order to avoid circularity.
313 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
314 from argc if argc was 0 initially.
316 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
317 in generation of libpath.h.
319 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
321 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
322 libguile from 2 to 3.
324 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
326 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
328 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
330 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
331 scm_set_port_column_x, scm_port_filename,
332 scm_set_port_filename_x): Removed optional arguments. Added
333 proper argument checking.
335 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
336 stack size in machine words.
338 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
339 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
340 to Ole Myren Röhne.)
342 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
344 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
345 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
347 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
350 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
351 procedure apply: Copy argument lists before pushing them unto the
352 environment so that the environment won't get mutated due to
353 manipulation of procedure arguments. This should perhaps be
354 regarded as a temporary solution until someone finds a more
355 efficient one. (Thanks to Maciej Stachowiak.)
357 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
359 * script.c (scm_compile_shell_switches): Use "guile" as default
360 zero arg if argc is NULL.
362 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
364 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
365 is zero. (Thanks to Dirk Herrmann.)
367 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
369 * ports.c (scm_add_to_port_table): First line is now line 0
370 (was 1). (Interface changed according to suggestion by Per
373 * backtrace.c (display_header): Add 1 to line and column numbers
374 when presenting them to the user.
376 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
377 from debug.c --> eval.c
379 * eval.h, eval.c (scm_eval_options_interface): New options
381 (SCM_EVAL_STACK): New option: Size of newly created stacks,
382 i.e. stacks for new threads.
384 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
386 * eval.c (unsafe_setjmp): Removed with #if 0.
388 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
391 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
392 to avoid compiler warnings.
394 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
396 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
398 * throw.c (handler_message): Print message on current error port
399 instead of default error port. (Thanks to Maciej Stachowiak.)
401 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
403 * ports.c (scm_add_to_port_table): allocate in units of
404 struct scm_port_table *, not struct scm_port_table.
405 * posix.c (scm_close_pipe): remove the port from the port table
407 Thanks to Rob Engle for both fixes.
409 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
411 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
412 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
414 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
416 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
418 * backtrace.c (display_error_body, display_backtrace_body),
419 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
420 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
421 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
422 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
425 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
426 don't receive the jmpbuf arg anylonger.
427 (scm_catch): Don't accept a #f tag.
428 (scm_throw): Check that key is a symbol.
429 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
431 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
433 * async.c (async_pending): Removed declaration.
435 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
437 * dynwind.c (scm_wind_chain): New debug function.
439 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
440 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
441 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
442 extra layer of functions around the body and handler of a thread.
443 This extra layer makes sure that the handler is called in the
444 dynamic context of the surround (= empty dynwind list), but under
445 the *dynamic root* of the body. We can not use the dynamic root
446 of the surround since that root belongs to another thread => stack
447 is not handled correctly. It may seem ugly to use this extra
448 layer, but the extra cost in terms of execution time is really
449 negligible compared to the total amount of time required to create
450 a thread, and it would reduce maintainability to duplicate the
451 crucial and complicated steps performed by cwdr.
453 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
454 (SCM_ALLOW_INTS): Added thread switching code before interrupts
455 get re-enabled. The important effect of this is that interrupts
456 are blocked during thread switching so that thread data structures
457 don't risk getting messed up by an unfortunate signal.
458 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
459 seems to do more aggressive optimization which actually move
460 instructions around in these macros in a fatal way. Therefore:
461 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
462 just superstitious...)
463 (SCM_TICK): Maybe do a context switch and take care of asyncs.
464 This macro should be used instead of SCM_ASYNC_TICK since the
465 latter doesn't do context switches any more.
467 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
468 instead of SCM_ASYNC_TICK.
470 * coop.c, iselect.c: Since thread switches are now performed with
471 interrupts masked, we can't use the old mechanism of delivering
472 signals immediately when they arrive. Signals must instead be
473 delivered when the asyncs run *after* the end of the critical
474 section in scm_internal_select. But this also means after context
475 switch so that the signal will be delivered to a different thread.
476 To avoid this, I have changed the protocol of
477 coop_wait_for_runnable_thread and friends so that they are allowed
478 to return the original thread. So, if a signal arrives during
479 scm_internal_select, we won't any longer be forced do a context
480 switch, but can remain in the same thread and deliver the signal
483 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
484 scm_asyncs_pending and made it global.
486 * iselect.c: Small fixes.
488 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
489 coop_condition_variable_init, coop_condition_variable_wait,
490 coop_condition_variable_signal): Changed return type from `void'
491 to `int'. This is to adhere closer to the pthreads interface.
492 This, in turn, is part of an attempt to provide C versions of the
493 mutex and condition variable primitives which can be part of a
494 frontend to COOP or pthreads.
496 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
497 coop_condition_variable_destroy): New functions.
499 * coop-threads.c (scm_wait_condition_variable): Use
500 coop_condition_variable_wait_mutex.
502 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
503 Definitions moved to coop-defs.h.
505 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
506 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
507 scm_cond_destroy): New C interface to mutecis and cond vars.
509 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
511 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
513 * iselect.c: Now several threads can wait on the same file
514 descriptor. The behaviour is compatible with OS select: All
515 threads waiting for the fd return with the same status.
517 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
519 * coop-threads.c, threads.h (scm_spawn_thread): New function.
520 Can spawn a thread from application C code.
522 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
524 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
525 gh_doubles2scm): New functions.
527 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
529 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
530 commented-out version of gh_eval_str()
532 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
534 * socket.c (scm_bind): free soka after use.
536 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
538 * stime.c (tzvar): new variable.
539 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
540 avoid memory leaks when allocating.
542 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
544 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
547 * gc.c, tags.h: Doc fixes.
549 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
551 * eval.c (macro-eval!): Removed. This function was a design bug.
552 It allowed memoized code to leak out to the scheme level. Most
553 things that you could do with `macro-eval!' can be done with
556 1997-12-20 Tim Pierce <twp@skepsis.com>
558 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
559 scm_fgets now depends on ftell(3) to know how many bytes were
562 1997-12-15 Tim Pierce <twp@skepsis.com>
564 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
565 dealing with strings.
567 1997-12-13 Tim Pierce <twp@skepsis.com>
569 Make %read-line more suitable for implementing read-line efficiently.
570 * ioext.c (scm_read_line): Strip the terminating newline from a
571 string, and return a cons of the string and its terminator.
573 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
574 of the string that is read is stored in this memory location.
575 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
576 * genio.c, genio.h (scm_do_read_line): Update caller.
577 * ports.h (scm_ptobfuns): Update typedef.
578 * fports.c (scm_fptob, scm_pipob): Update struct.
580 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
582 * filesys.c (set_element): Return file descriptor.
583 (fill_select_type): Return the highest file descriptor.
584 (scm_select): Tell select about the highest file descriptor. On
585 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
586 Therefore the extra overhead for calculating the maximum fd seems
587 to be more than compensated. Is this correct? In any case,
588 scm_internal_select will be much faster with this info.
589 (scm_select, fill_select_type, set_element): Don't accept any kind
590 of object in the file descriptor list or vector.
592 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
594 * iselect.c (finalize_fd_sets): Bugfix.
596 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
598 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
599 when using scm_internal_select (since we might switch to another
602 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
604 * simpos.c (scm_system): always define: use sysmissing if not
605 available. Check for HAVE_SYSTEM instead of _Windows (does
606 Windows lack system or does it have an unusable one?).
607 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
608 Let the argument be optional: if not supplied, call system(NULL).
610 * ports.c (scm_close_port): relax the type check from OPPORTP to
611 PORTP; closing a closed port is allowed.
613 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
615 * fports.c (scm_fgets): Return if the last char in a chunk is
616 newline. When fgets returns a string whose length is `size-1', it
617 is ambiguous whether a whole line was retrieved, so we must check
618 explicitly whether a line terminator is present.
620 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
622 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
623 before taking the CDR. (Thanks to Harald Meland.)
625 * filesys.c (scm_stat): Slightly optimized.
627 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
629 * ports.c (scm_close_port): Make sure the port is open before
632 * guile-snarf.in: Pass args through to gcc in a way that preserves
633 whitespace boundaries. (Thanks to Greg Badros.)
635 1997-12-02 Tim Pierce <twp@skepsis.com>
637 * stacks.c (scm_frame_procedure): Reverse the logic in the return
638 statement. (Thanks to Doug Evans for pointing this out.)
640 1997-12-01 Tim Pierce <twp@skepsis.com>
642 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
644 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
646 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
647 errno macro expansion of this field name. (errno is a C
648 preprocessor macro on some systems.)
650 1997-11-29 Tim Pierce <twp@skepsis.com>
652 * iselect.c: Doc fix.
654 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
656 * init.c (scm_start_stack): Removed initialization of
657 scm_the_last_stack_var.
659 * backtrace.h: Declare scm_the_last_stack_var.
661 * backtrace.c: Define scm_the_last_stack_var.
663 * root.c (mark_root): Don't mark the_last_stack_var.
665 * root.h (scm_root_state): Removed the_last_stack_var.
667 * throw.c: Added #include "fluids.h"
668 (ss_handler): `the-last-stack' is now a fluid.
670 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
671 --> the_last_stack_fluid.
673 * backtrace.c: Added #include "fluids.h"
674 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
675 (scm_backtrace): `the-last-stack' is now a fluid.
677 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
678 after scm_init_fluids.
680 1997-11-28 Tim Pierce <twp@skepsis.com>
682 * iselect.c: #ifdef USE_THREADS around thread-related includes.
684 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
685 DLSYM_ADDS_USCORE to decide whether to add an underscore.
687 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
689 * iselect.c (coop_next_runnable_thread,
690 coop_wait_for_runnable_thread): Disable interrupts so that no
691 async is executed before a potential error_revive.
692 (scm_internal_select): Disable interrupts during the parts of the
693 code which manipulate the sleep queue and the file descriptors.
695 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
697 * Makefile.am: Added iselect.c and iselect.h.
699 * coop.c (coop_qinit): Initialize fields used by
701 (coop_qget, coop_qget, coop_tmp_queue): Made global.
702 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
703 replacement in iselect.c.
704 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
705 coop_join): If GUILE_ISELECT enabled, use
706 coop_wait_for_runnable_thread instead of
707 coop_next_runnable_thread.
708 (usleep, sleep): New replacements for system functions if
709 GUILE_ISELECT is enabled.
711 * coop-threads.h: Declare coop_wait_for_runnable_thread.
713 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
715 * filesys.c: Added #include "iselect.h". Moved FD-macros to
716 iselect.h. Implement Scheme level `select' using
717 scm_internal_select. (See NEWS.)
719 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
721 * init.c: Call scm_init_iselect.
723 * iselect.h, iselect.c: New files. Implements
724 scm_internal_select. (See NEWS.)
726 1997-11-27 Tim Pierce <twp@skepsis.com>
728 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
729 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
730 and scm_must_free, since ultimately the string returned will be copied
731 by scm_makfrom0str anyway. Also, read any characters that may have
732 been pushed onto the port with scm_ungetc.
733 * ports.c (scm_generic_fgets): Same as for scm_fgets.
734 * ioext.c (scm_read_line): Free string after Guilifying it.
735 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
737 1997-11-26 Anthony Green <green@hoser.cygnus.com>
739 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
741 * gh.h: Safely wrap prototypes for c++ usage.
743 1997-11-25 Mark Galassi <rosalia@cygnus.com>
745 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
746 gh_repl (argc, argv).
748 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
750 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
751 and to invoke scm_shell().
752 (gh_launch_pad): took out the loading of boot-9.scm from here,
753 since it is probably best to let the user control that. In fact,
754 gh_repl() now invokes scm_shell() which does that.
756 1997-11-23 Mark Galassi <rosalia@cygnus.com>
758 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
761 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
763 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
764 yesterday's underscore patch. (Thanks to Marius Vollmer for
767 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
769 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
770 DLSYM_ADDS_USCORE is not defined.
772 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
774 * gh_data.c (gh_uniform_vector_length):
775 (gh_uniform_vector_ref): started implementing the uniform types in
778 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
780 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
781 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
783 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
785 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
786 configure.in was changed).
788 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
790 * Makefile.am (modinclude_HEADERS): Include readline.h here.
791 * Makefile.in: Regenerated.
793 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
795 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
796 OPORT is an `open' port, not an output port.
798 * filesys.c (scm_close, set_element, get_element, scm_chown,
799 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
800 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
801 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
802 scm_close_port, scm_port_line, scm_set_port_line_x,
803 scm_port_column, scm_set_port_column_x, scm_port_filename,
804 scm_set_port_filename_x, scm_port_mode,
805 scm_close_all_ports_except, scm_set_current_output_port,
806 scm_set_current_error_port): Likewise
807 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
808 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
810 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
811 * backtrace.c (display_backtrace_body): Likewise
812 * fports (scm_setvbuf): Likewise
813 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
814 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
815 scm_getpeername, scm_send, scm_sendto): Likewise
816 * unif.c (scm_uniform_array_write): Likewise
818 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
820 Minor problems with substring-related tag changes.
821 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
822 exactly what we want to leave in to detect substrings.
823 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
824 * tags.h: Fix diagrams and comments describing the S tag bit;
825 remove vestigial remarks about the D tag bit.
826 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
827 * strings.c: Formatting tweaks.
829 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
830 variable first; then SCHEME_LOAD_PATH, with a warning message.
831 (scm_parse_path): New function.
832 * script.c: Doc fixes.
834 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
836 Readline support, from Daniel Risacher.
837 * readline.c, readline.h: New files.
838 * init.c: #include "readline.h".
839 (scm_boot_guile_1): Call scm_init_readline, if we have it.
840 * Makefile.am (libguile_la_SOURCES): Include readline.c.
841 * Makefile.in: Regenerated.
842 * scmconfig.h.in: Regenerated, after change to ../configure.
844 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
846 * gh.h: gh_vector_set -> gh_vector_set_x
848 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
850 * gh_data.c (gh_vector_set_x): changed name to make it consistent
851 with the ! -> _x mapping when going from Scheme to C.
853 1997-10-19 Mark Galassi <rosalia@cygnus.com>
863 (gh_assoc): added these gh_ functions implemented as macros.
865 * gh_predicates.c (gh_null_p):
866 (gh_string_equal_p): added these two missing predicates.
868 * gh_list.c (gh_append):
873 (gh_set_cdr_x): added these routines as I go through and try to
874 complete the picture R4RS functions that should be mirrored in the
877 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
879 * tags.h (scm_tc7_substring): Changed the comment and code to
880 conform with the changes below. Folks! We have suddenly two new
881 free tc7 codes!!! Jummy, jummy!
883 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
885 * Makefile.in: Rebuilt.
886 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
888 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
889 * unif.c (scm_vector_set_length_x): Don't handle multibyte
891 * tag.c (scm_utag_mb_string, scm_utag_mb_substring): Removed.
892 (scm_tag): Don't handle multibyte strings.

898 * hash.c (scm_hasher): Don't handle mbstrings.
899 * gscm.c (gscm_run_scm): Don't init mbstrings module.
900 * gc.c (scm_gc_mark): Don't handle mbstrings.
901 (scm_gc_sweep): Likewise.
902 * eval.c (SCM_CEVAL): Don't handle mbstrings.
903 * eq.c (scm_equal_p): Use SCM_TYP7S, not SCM_TYP7SD.
904 * tags.h (SCM_TYP7SD): Removed.
905 (SCM_TYP7D): Removed.
906 (scm_tc7_mb_string): Removed.
907 (scm_tc7_mb_substring): Removed.
908 * print.c (scm_iprin1): Handle char printing directly. Don't
910 Don't include "mbstrings.h".
911 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
912 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
914 Don't include "mbstrings.h".
915 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
916 (SCM_SYMBOL_SLOTS): Define as 4.
917 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
918 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,

920 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
921 struct.c, threads.c, throw.c, unif.c, variable.c: Use new
922 ("gen"-less) I/O function names.
923 * ports.c (scm_add_to_port_table): Don't set port's
925 * ports.h (scm_port_representation_type): Removed.
926 (scm_string_representation_type): Removed.
927 (struct scm_port_table ): Removed representation field.
928 (SCM_PORT_REPRESENTATION): Removed.
929 (SCM_SET_PORT_REPRESENTATION): Removed.

937 (scm_do_read_line): Renamed from scm_gen_read_line.
938 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
939 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
941 1997-10-12 Mark Galassi <rosalia@cygnus.com>
943 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
945 * gh_test_c.c (c_vector_test): some improvements on the vector
948 * gh.h (gh_vector): this used to exist but do the wrong thing.
949 Now it (almost) does the right thing, though it takes a list
950 instead of the individual arguments. I need to see how it could
952 (gh_list_to_vector): added this function as a macro. Corresponds
953 to Scheme's (list->vector ...).
954 (gh_vector_to_list): added this function as a macro. Corresponds
955 to Scheme's (vector->list ...).
957 * gh_data.c (gh_vector_ref): renamed from gh_vref to
958 gh_vector_ref, so that it resembles the Scheme routines more.
959 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
960 resembles the Scheme routines more.
961 (gh_make_vector): this used to be (stupidly) called gh_vector().
962 This is the right name, since it does the same thing as the Scheme
963 (make-vector ...) procedure.
965 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
967 * ports.h: #include "libguile/print.h"

970 Some indentation fixes.
972 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
973 longer a user field; New field: class_flags.
975 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
977 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
979 * gh_data.c (gh_bool2scm): new function which replaces
980 gh_int2scmb(), which is now tagged as obsolete.
982 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
984 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
985 macros should by convention not test for NIMPness.)
986 (SCM_COERCE_OPORT): Adjust indentation.
988 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
989 SCM_NIMP test before SCM_PRINT_STATE_P.
991 * struct.c, struct.h, gc.c: Renamed:
992 scm_struct_i_layout --> scm_vtable_index_layout
993 scm_struct_i_vcell --> scm_vtable_index_vcell
994 scm_struct_i_vtable --> scm_vtable_index_vtable
995 scm_struct_i_printer --> scm_vtable_index_printer
996 scm_struct_i_vtable_offset --> scm_vtable_offset_user
998 * struct.c (scm_print_struct): Use new printer slot; Default
999 printing: Also output hex code of vtable so that type identity
1000 will be indicated as well.
1001 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1002 Removed struct_printer_var; Removed struct-vtable-offset;
1003 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1004 vtable-offset-user): New constants.
1006 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
1007 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
1008 If this slot contains a procedure, use that to print structures of
1009 the type represented by this vtable.
1011 * print.c (scm_iprin1): Don't print arguments of macro
1012 transformers. (They are always: exp env.); Bugfix: Unmemoize
1013 transformer source with correct environment.
1015 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1017 Streamlining of call-with-dynamic-root:
1019 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
1020 there is now only one catch.
1021 (cwdr_outer_body): Removed.
1022 (cwdr_handler): New function.
1023 (scm_internal_cwdr): New function to perform the function of cwdr
1024 but take args that are more useful to C code. Also, the handler
1025 is now invoked *outside* of the new dynamic root, like the docs
1026 say. We no longer have to catch absolutely all errors, the caller
1027 is responsible for using a handler that does not throw, if he
1029 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1030 * root.h (scm_internal_cwdr): New prototype.
1032 Even more but risky streamlining:
1034 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1035 allocation of the jumpbuf of a root continuation. The changes
1036 below are controlled by it. They are now deactivated.
1037 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1038 the JMPBUF of the scm_rootcont to NULL before returning.
1040 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1041 when they are non-NULL.
1042 (scm_gc_mark): Likewise, mark only when non-NULL.
1044 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1045 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1047 * gc.c (scm_done_malloc): New function.
1048 gc.h (scm_done_malloc): New prototype.
1050 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
1051 (struct scm_print_state) [revealed]: New field.
1052 (scm_print_state_vtable): Make visible to the outside world for
1053 type checking purposes.
1054 (scm_valid_oport_value_p): New prototype.
1056 * print.c (scm_valid_oport_value_p): New function to check whether
1057 a certain value is acceptable as a port argument.
1058 (scm_print_state_vtable): New variable.
1059 (scm_free_print_state): Set `revealed' field to false.
1060 (scm_iprin1): Call user supplied closure printer with
1061 scm_printer_apply. Print in the traditional way when there isn't
1062 one or when it returns #f.
1063 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1064 Accept a port/print-state pair in addition to just a port.
1065 (scm_prin1): Don't return the print_state to the pool when it has
1067 (scm_printer_apply): Set `revealed' field of print_state to true.
1068 (scm_init_print): Set scm_print_state_vtable.
1069 (print_state_fluid, print_state_fluid_num): Removed.
1071 * throw.h (scm_handle_by_proc_catching_all): New prototype
1072 throw.c (scm_handle_by_proc_catching_all): New function
1074 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1076 * Makefile.in: Regenerated with automake 1.2c.
1078 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1080 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1081 was looping endlessly.
1083 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1085 * strports.c (scm_eval_string): Don't close the port.
1087 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1088 former returns a nice normal integer. (Thanks to Daniel
1091 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1093 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1094 makefile variable as a build parameter called LIBS. The
1095 build-guile program will use this, for the time being.
1096 * Makefile.in: Regenerated.
1098 Thanks to Shiro Kawai:
1099 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1100 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1103 * Makefile.in: Regenerated with automake 1.2a.
1105 * script.c (scm_compile_shell_switches): If we hit the -c or --
1106 arguments, don't set the car of (command-line) to scm_usage_name,
1107 the prettified name of the guile executable; give it the full
1108 path, the way shells usually handle $0.
1110 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1112 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1113 Scheme-level name `array-map' and renamed `serial-array-map' to
1114 `serial-array-map!'.
1116 * backtrace.c: Introduced exception handlers which now enclose
1117 `display-error' and `display-backtrace' so that error reporting
1118 won't get into infinite loops if an error occurs during displaying
1119 of the error. This can very easily happen with user supplied
1120 print call-back routines.
1122 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1124 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1125 the names `serial-array-map' and `array-map' should be removed.)
1127 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1129 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1130 Added #include "objects.h"
1132 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1133 Add #include "feature.h".
1135 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1136 (modinclude_HEADERS): Added objects.h.
1138 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1139 This test is needed at many places in the code and should be
1140 abstracted. (Motivated by the need of this test in libguiletk.)
1142 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1143 (scm_eval_string), load.c (scm_primitive_load,
1144 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1145 Use SCM_EOF_OBJECT_P.
1147 * eval.c (scm_init_eval): Add feature `delay'.
1149 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1151 * scmhob.h: Removed.
1153 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1155 * list.h (SCM_LISTn): New macros. Make list creation in C code
1156 prettier. The idea comes from STk.
1158 * sequences.h, sequences.c, append.h, append.c: Removed. These
1159 files implemented non-R4RS operations which would encourage
1160 non-portable programming style and less easy-to-read code.
1162 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1165 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1166 sequences.h, #include append.h.
1168 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1171 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1173 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1175 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1177 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1179 * eval.c: Added #include "objects.h"
1181 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1184 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1185 adjacent smob numbers.
1187 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1189 * procprop.h: Added declaration of scm_i_inner_name.
1191 * gsubr.c: New global symbol scm_i_inner_name.
1193 * debug.c (scm_procedure_name): Try procedure property
1194 `inner-name' if `name' fails.
1196 * print.c (scm_iprin1): Use scm_macro_name.
1198 * eval.c (scm_m_define): Give names to macros as well; Only the
1199 first top-level definition gives a procedure/macro a name.
1200 Otherwise confusing names can turn up in backtraces.
1201 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1202 `name'; Give names to macros as well.
1204 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1205 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1208 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1210 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
1212 (prinmacro): Removed. The code has been moved/merged into print.c
1213 in order to decrease code redundancy. We want macros to print in
1214 a way equivalent to procedures, and it would be silly to duplicate
1215 the required code. (We don't want to maintain two places.)
1216 (macrosmob): Print field is now a NULL pointer.
1218 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1219 scm_macro_transformer): New prototypes.
1220 (scm_tc16_macro): Declared.
1222 * * print.c (scm_iprin1): Added code for printing of macros. Macros
1223 are now printed in a way equivalent to procedures.
1225 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1227 * procs.h (scm_closure_p): Added declaration.
1229 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1231 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
1232 Shouldn't pass "heap" as the subr name.
1234 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1236 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
1237 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
1238 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1239 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1240 SCM_BOOL_T. Any non-false value is true.
1242 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1244 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1245 scm_gensym): Added prototypes.
1247 * symbols.c (scm_gensym): New function. This will speed up
1248 certain types of applications (such as macro systems) which
1249 generate lots of symbols.
1251 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1253 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
1255 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
1257 * unif.c (scm_shap2ra): tighten the checking of the array dimension
1258 specifier, since (2) or (2 . 3) would cause SEGV.
1259 (scm_transpose_array): more argument checking fixes.
1261 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1263 * Makefile.in: Regenerated.
1265 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1267 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
1269 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1271 * error.c, error.h (scm_error_callback): Removed (see NEWS).
1273 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
1275 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
1276 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
1279 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
1280 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1281 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
1282 scm_array_p, scm_array_rank, scm_array_dimensions,
1283 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
1284 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
1285 scm_array_prototype): Added case scm_tc7_wvect.
1287 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
1289 * errno.h: prototype for scm_strerror.
1290 * error.c (scm_strerror): new procedure.
1292 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1294 * list.c (scm_list_append_x): Allow non-pair as last argument.
1295 This is consistent with the R4RS append and is probably the
1296 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1298 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1300 * stime.h: prototype for scm_times.
1301 * stime.c (scm_times): new procedure.
1302 * ioext.c (scm_fseek): if the first argument is a file descriptor
1304 (scm_ftell): if the first argument is a file descriptor call lseek
1306 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
1307 * filesys.c (scm_chmod): if the first argument is a file descriptor,
1309 (scm_chown): if the first argument is a port or file descriptor,
1311 (scm_truncate_file): new procedure.
1312 Add DEFER/ALLOW INTS to a few other procedures.
1313 (scm_fsync): new procedure.
1314 (scm_open_fdes): new procedure.
1315 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
1317 (scm_fcntl): the first argument can now be a file descriptor. The
1318 third argument is now optional.
1320 * posix.c (scm_execl, scm_execlp): make the filename argument
1321 compulsory, since omitting it causes SEGV.
1322 (scm_sync): return unspecified instead of #f.
1323 (scm_execle): new procedure.
1324 (environ_list_to_c): new procedure.
1325 (scm_environ): use environ_list_to_c. disable interrupts.
1326 (scm_convert_exec_args): take pos and subr arguments and
1327 improve error checking.
1329 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1331 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1332 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1333 argument to SCM_ASSERT. Furthermore, the name of the function
1334 should be passed as first argument when signalling
1335 SCM_WNA. (Thanks to Thomas Morgan)
1337 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1338 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1339 dispatches on the number of actual args has a default case
1340 reporting an internal error. This is a vestige from a version
1341 that mallocated a SCM vector to hold the arguments. In the
1342 current version this check is too late: if it ever happens we will
1343 have already overstepped the bounds of the array.
1345 Also, the patch [...] adds a check for too many actual arguments."
1347 mdj: Removed check for "internal programming error".
1349 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1351 * gh_io.c (gh_write): New function.
1353 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
1354 throw.c (scm_internal_stack_catch): New sibling to the other catch
1355 functions. Code moved from gh_eval.c.
1356 throw.h: Added header.
1357 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
1358 scm_internal_stack_catch.
1360 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1362 * ioext.h: fix up prototypes.
1363 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
1364 Scheme name is now dup->fdes.
1365 (scm_dup_to_fdes): make the second argument optional and
1366 fold in the functionality of scm_primitive_dup.
1367 (scm_primitive_dup): deleted.
1369 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1371 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
1372 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
1373 ultrix are defined. Use setvbuf instead of setbuf.
1374 (scm_setvbuf): new procedure.
1375 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
1376 (scm_setfileno): moved from ioext.c.
1377 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
1378 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
1380 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1382 * fluids.c (scm_fluid_p): New function.
1383 * fluids.h (scm_fluid_p): New prototype.

1387 * print.c (scm_iprin1): Enter printed structures into the print
1388 state as nested data while they are printed.
1389 (print_state_fluid, print_state_fluid_num): New variables.
1390 (scm_init_print): Initialize them.
1391 (scm_iprin): If print_state_fluid carries a print_state, use that
1392 instead of creating a new one.
1393 (scm_printer_apply, apply_stub, struct apply_data): New
1394 definitions to help with calling printer functions written in
1396 * print.h (scm_printer_apply): New prototype.

1409 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
1410 SCM_ASSERT: arg comes before pos.
1412 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1414 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
1415 to a list of length zero correctly.
1417 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1419 Supply an `fgets' method for port objects to do fast line i/o.

1433 * ioext.h: removed scm_duplicate_port prototype.
1435 * ioext.c (scm_primitive_dup2): return the new file descriptor
1436 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
1438 (scm_fdopen): bug fix: don't try to make port unbuffered until its
1439 stream has been set.
1440 (scm_duplicate_port): deleted, there's now an implementation in
1442 (scm_primitive_dup2): do nothing if newfd == oldfd.
1444 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
1446 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
1449 * ioext.h: new prototypes.
1450 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
1452 * fluids.c (next_fluid_num): don't do
1453 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
1455 * ports.h: prototypes too.
1456 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
1458 * fports.h: prototype too.
1459 * fports.c (scm_evict_ports): moved from ioext.c.
1461 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>

1468 and ports (scsh compatible).
1470 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
1473 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
1475 * fluids.c, fluid.h: New files.
1476 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
1477 (modinclude_HEADERS): Added "fluids.h"
1479 * init.c: Include "fluids.h". (scm_boot_guile_1): Added call to

1485 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
1486 (scm_make_root): Call scm_copy_fluids to make fluid bindings
1487 unique for the new root when it has a parent.
1489 * smob.h: Include "libguile/print.h" to make scm_print_state
1492 * dynl.c (free_dynl_obj): New function to free the dynamic object
1493 data. (dynl_smob): Use it.
1494 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
1495 the dynamic object data below the linking of the object to avoid
1496 memory leak when the linking code throws an error. Now the code
1497 leaks a whole dynamically linked library when must_malloc throws,
1498 but that should be much less likely.
1500 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
1502 Changes to compile under gnu-win32, from Marcus Daniels:
1503 * stime.c (tzset): If tzset isn't provided, make it a NOP.
1504 (scm_localtime): Change SCM_EOF to SCM_EOL.
1505 (scm_mktime): Likewise.
1506 * socket.c: Don't include sys/un.h unless autoconf tells
1507 us Unix domain sockets are available.
1508 (scm_fill_sockaddr): Ignore Unix domain code.
1509 (scm_addr_vector): Likewise.
1510 (scm_init_addr_buffer): Likewise.

1516 * posix.c (scm_getgroups): Don't include unless support function
1517 was found during autoconf (in this case, getgroups).
1518 (scm_setpwent): For setpwent.
1519 (scm_setegid): For setegid.
1520 * net_db.c (scm_inet_netof): Don't include unless support
1521 function was found during autoconf (in this case, inet_netof).
1522 (scm_lnaof): For inet_lnaof.
1523 (scm_inet_makeaddr): For inet_makeaddr.
1524 (scm_getnet): For getnetent, getnetbyname, getnetbyaddr.

1535 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
1536 scm_misc_error, not SCM_EOF.
1538 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
1539 arguments for formatting the error message, not SCM_BOOL_F. I
1540 think this is left over from the (eq? '() #f) days.
1542 * read.c (recsexpr): Give this a dummy definition if
1543 DEBUG_EXTENSIONS isn't #defined.
1545 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>

1550 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>
1552 * root.c (cwdr_outer_body): Bugfix: Pass `c' instead of `&c' to
1555 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
1557 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
1558 alloca.lo will be included in @LIBLOBJS@. Something better than
1559 this should be possible.
1560 * Makefile.in: Regenerated.
1562 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1564 * simpos.h: prototype for scm_primitive_exit.
1565 * simpos.c (scm_primitive_exit): new procedure, terminates the
1566 process without unwinding the stack.
1568 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
1570 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
1571 argument and logior its components together, so the user doesn't
1572 have to do this explicitly. Also, if regexp/basic is supplied, then
1573 turn off REG_EXTENDED.
1574 (scm_init_regex_posix): New regexp/basic symbol.
1575 (REG_BASIC): #define this if it is not already present.
1577 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1579 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
1580 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
1581 (CLEANFILES): New target, clean versiondat.h, libpath.h.
1582 (DISTCLEANFILES): New target, clean *.x.
1583 * Makefile.in: Regenerated.
1585 Tue Jun 24 00:29:07 1997 Jim Blandy <jimb@floss.red-bean.com>
1587 * script.c (scm_compile_shell_switches): Add 1997 to copyright
1588 years in usage message.
1590 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
1591 * Makefile.in: Regenerated.
1593 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
1594 flag; I don't think we support it.
1595 (scm_make_regexp): Make sure the user doesn't pass the
1598 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
1600 (scm_init_regex_posix): Define constants for the REG_mumble flags;
1601 name them according to the SCSH convention: regexp/mumble.
1603 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
1605 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
1607 * Makefile.am (libpath.h): Include the values of all the standard
1608 Makefile directory variables. Print a message, but don't print
1610 (versiondat.h): Print a message, but don't print all the commands.
1611 * load.c: #include "alist.h".
1612 (init_build_info): New function.
1613 (scm_init_load): Call it.
1614 * Makefile.in: Regenerated.
1616 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
1618 * root.c: Establish a reliable catch-all handler for the new root.
1619 After all the Scheme handler function might signal an error too,
1620 and we don't want to lose that.
1621 (cwdr_inner_body): Renamed from cwdr_body.
1622 (cwdr_outer_body): New function, to establish the user's handler,
1623 and pass control to cwdr_inner_body.
1624 (cwdr): Establish the reliable catch-all handler here, and pass
1625 control to cwdr_outer_body.
1626 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
1627 the user's handler through to cwdr_outer_body.
1628 * throw.c (scm_handle_by_message): Move guts into....
1629 (handler_message): New static function.
1630 (scm_handle_by_message_noexit): New function.
1631 * throw.h (scm_handle_by_message_noexit): New prototype.
1633 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
1634 across this. Only works on GCC. Otherwise, we hope for the best.
1635 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
1636 the feeling that real thread systems will not need this...
1638 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
1640 Try to detect when people are using one version of libguile and a
1641 different version of ice-9. People have been skewing things and
1642 sending in bug reports.
1643 * Makefile.am (versiondat.h): New file to generate.
1644 * version.c: #include "versiondat.h", to get version info.
1645 (scm_libguile_config_stamp): New function.
1646 * script.c: #include "version.h".
1647 (scm_compile_switches): Call scm_version to get version number.
1648 * scmconfig.h.in, Makefile.in: Regenerated.
1649 * Makefile.in: Regenerated.
1651 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
1652 primitive definitions under their Scheme names.
1654 * Makefile.am (libguile_la_LDFLAGS): Update library version to
1655 1:2. Helps avoid confusion between installed and uninstalled libs.
1657 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
1660 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
1661 backslash from definition; this should be used like: GDB_INTERFACE;
1663 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1665 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
1666 new port unbuffered until its stream has been set.
1668 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
1670 * ports.h: new prototype.
1671 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
1673 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
1675 Make things compile neatly under Sun's C compiler.
1676 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
1677 * extchrs.c (xmbtowc): Make the second arg a normal char, not
1678 unsigned, because that's what the ANSI function takes.
1679 * extchrs.h (xmbtowc): Corresponding change to prototype.
1680 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
1682 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
1683 argument plain char *.
1684 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
1686 * tag.c (scm_tag): Remove unreachable statement.
1687 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
1688 top of the word, it should be unsigned.
1690 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
1691 is defined, to avoid warnings; it's only used in the
1692 conflict-checking code. Which might go away anyway.
1693 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
1694 conditionals; put the label definition in an #if too, to stifle
1697 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
1698 ChangeLog-threads in the distribution.
1699 * Makefile.in: Regenerated.
1701 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1703 * guile-snarf.in: Changed regexp to support CPPs that insert
1704 whitespace between lexical tokens (which munges the `%%%' snarf
1707 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1709 * load.c (scm_init_load_path): Append $(datadir)/guile to
1710 %load-path, so modules do not have to be installed in Guile's
1711 current version directory.
1713 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
1715 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
1716 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
1717 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
1718 call the sysdep functions with deferred ints.
1719 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
1720 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
1721 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
1724 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
1727 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
1729 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
1731 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
1733 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
1736 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
1738 * eval.c (scm_lookupcar1): New procedure to cope with a race
1739 condition during lookup (when using threads).
1740 (scm_lookupcar): Implement in terms of scm_lookupcar1.
1741 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
1744 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
1746 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
1747 supplied. (Change from Tim Pierce.)
1749 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
1751 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
1752 23:47:01 1997" changelog: Slots are now initialized with `#f' by
1753 default and not `()'. `#f' is the canonical non-value in Scheme,
1756 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1758 * struct.c (struct_printer): New variable that holds a handle on
1759 the Scheme variable *struct-printer*. This variable can be set by
1760 Scheme code to override the printing of structures.
1761 (scm_print_struct): If struct_printer is set, call it. If it is
1762 not set, or returns #f, print the structure in the old fashion.
1763 Include "eval.h" for scm_apply.
1765 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
1767 * struct.c (scm_struct_ref, scm_struct_set_x): Use
1768 scm_struct_i_n_words to get the number of fields, not
1769 -scm_struct_n_extra_words.
1771 On the route to fancier struct printing:
1772 * struct.c (scm_print_struct): New function to print a structure.
1773 Include "genio.h" to support it. This function doesn't do
1774 anything interesting right now, but I think it should be here
1776 * struct.h: Include "print.h" and add prototype for
1778 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
1779 print structures ourself.
1781 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
1783 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
1784 before applying the handler in case it doesn't return.
1786 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
1788 * scmsigs.h, async.h: updated.
1790 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
1793 * posix.c (scm_uname): interpret only negative values as an error.
1794 Solaris normally returns a positive value.
1796 * script.c (scm_compile_shell_switches): if we are not going into
1797 an interactive repl, set scm_mask_ints to zero so that asyncs can
1800 * simpos.c (scm_system): don't ignore/unignore signals around
1803 * posix.c (scm_open_pipe): don't ignore/unignore signals around
1806 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
1807 done in boot-9.scm instead.
1809 * scmsigs.c, async.c: Major rewriting of signal handling code.
1810 (scm_sigaction): new procedure.
1811 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
1813 (scm_raise): return unspecified, throw error on failure.
1815 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
1817 * regex-posix.c (scm_init_regex_posix): Register the "regex"
1818 feature, to help boot-9.scm decide whether to import the regex
1821 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
1823 * eval.c: Include scmconfig.h at the beginning of the file so that
1824 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
1827 * regex-posix.c: #include "_scm.h" before conditionally #including
1828 <regex.h>; the former defines HAVE_REGCOMP.
1830 * regex-posix.c: #include <regex.h> conditionally, so the file is
1831 CPP'able (for dependency scanning) even on systems that don't have
1834 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
1836 Add new R4RS-compliant syntax for keywords.
1837 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
1838 regardless of the setting of the `keywords' read option.
1839 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
1840 can be re-read no matter what the setting of the `keywords' read
1843 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
1845 Add support for POSIX regular expressions.
1847 * regex-posix.c, regex-posix.h: New files. (Some code
1848 is taken liberally from rx/rgx.c in the old Guile dist.)
1850 * init.c: Include regex-posix.h.
1851 (scm_boot_guile_1): Call scm_init_regex_posix.
1853 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
1854 Add regex-posix.[ch] sources.
1855 * Makefile.in: Regenerated.
1857 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
1858 to do this automatically? It didn't for me, bleh.)
1860 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
1862 * fports.c (print_pipe_port): New function.
1863 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
1864 latter doesn't even take the right arguments.
1866 * Makefile.am: Increment shared lib revision number. I think
1867 sometimes the uninstalled Guile finds the installed shared lib;
1868 Gord says doing this might help. As things turned out, I can't
1869 say whether it does.
1870 * Makefile.in: Regenerated.
1872 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
1873 passing it as the closure argument to scm_boot_guile. (Bill
1876 * ports.c (print_void_port, putc_void_port, puts_void_port,
1877 write_void_port, flush_void_port, getc_void_port, close_void_port,
1878 noop0): Use ANSI prototypes instead of K&R declarations, so the
1879 initialization of void_port_ptob gets aggressively type-checked.
1880 Fix arguments of print_void_port and write_void_port. (Bill

1914 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
1916 * script.c (scm_find_executable): Use prototype-style definition
1917 here; apparently it's not quite right to have const in a prototype
1918 and then use a K&R declaration. I wonder if stuff like this will
1919 go away if we compile with -Wrequire-prototypes, or whatever that
1920 is... (Bernard URBAN)
1922 * scmhob.h: New text from Bernard URBAN.
1924 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
1926 * script.c: Don't #define const on hpux. Configure takes care of
1927 this. (Thanks to Larry Schwimmer.)
1929 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
1930 decide whether to #include <unistd.h>, instead of listing a bunch
1931 of systems. Don't #include stdio twice. Removed dyked-out
1932 definition of scm_find_impl_file.
1934 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
1936 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
1937 library version info to 1:0.
1938 * Makefile.in: Regenerated.
1940 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

1944 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
1945 throw.c: Update copyright years; these files have been worked on
1946 significantly in 1997, but only had copyright years for 1996.
1947 Also, change name of copyright holder on some from Mikael
1948 Djurfeldt to Free Software Foundation; he has signed papers
1949 assigning the changes to the FSF.
1951 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
1952 reason not to give the user the option.
1954 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
1955 Return #f on end-of-file when scanning table (i.e. when called
1956 with no arguments). Try to catch errors, when we can.
1957 * posix.c (scm_getgrgid, scm_getpwuid): Same.
1959 * script.h (scm_shell_usage, scm_compile_shell_switches): New
1960 external declarations. These are useful.
1962 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
1964 * posix.c: don't include <sys/select.h> or define macros for
1965 select, since they were not used in this file.
1967 * filesys.c (scm_select): make the fifth parameter microseconds,
1968 not milliseconds. let the fourth parameter be either a real value
1969 or an integer or #f. The first, second and third arguments can
1970 now be vectors: the type of the corresponding return set will be
1972 (set_element, get_element): new static procedures.
1974 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
1976 * strports.c (scm_eval_string): New function.

1983 * fports.c (local_pclose): New function.
1984 (scm_pipob): Use it in the initializer here.
1987 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
1988 Use a meaningful error message when signalling an error. For
1989 this, scm_gethost must check h_errno rather than errno.
1991 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
1993 * Makefile.in: Regenerated, using automake-1.1p.
1995 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
1997 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
1998 not SCM_UNSPECIFIED.
2000 * script.c (scm_compile_shell_switches): don't append (quit) if
2002 (scm_shell): call scm_exit_status and exit on the result of the
2005 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2007 Ensure that shared substrings are handled properly when passed to
2008 a system call or other foreign function. Many thanks to Tim
2010 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2011 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2012 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2013 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
2014 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
2015 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
2016 (scm_display_error_message): use RO macros when strings may be RO.
2017 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
2018 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
2019 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
2020 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
2021 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
2022 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
2023 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
2024 scm_strftime), vports.c (scm_make_soft_port): use
2025 SCM_COERCE_SUBSTR to make sure shared substrings are

2030 * error.c (scm_error): Add newline to error message.
2032 * init.c (scm_init_standard_ports): Doc fix.
2034 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2036 * dynl-shl.c: Completely replaced with new code from Bernard
2039 * script.c (scm_ice_9_already_loaded): New variable.
2040 (scm_compile_shell_switches): Use it.
2042 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2044 * filesys.c (scm_input_waiting_p): add missing third argument to
2047 * stime.c (scm_localtime): copy the result of localtime before
2048 calling gmtime in case they share a buffer.
2049 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2052 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2054 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2056 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2058 * Makefile.am (check-local): New target, which causes 'make check'
2059 to run gh_test_c and gh_test_repl, with some trivial input.
2060 * Makefile.in: Rgnrtd.
2062 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2064 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2067 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2069 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2070 sure how this was supposed to work.
2071 (scm_async_click): don't send SCM_TICK_SIGNAL.
2072 (scm_init_async): don't initialize %tick-thunk.
2074 * the following change doesn't affect the Scheme interface:
2075 gc-thunk is called at the end of garbage collection. however it's
2076 no longer implemented by pretending it's a signal.
2078 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2079 system async corresponding to scm_gc_thunk.
2080 * async.h: declare scm_gc_async.
2081 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2082 gc-thunk directly, instead of going through a signal handler.
2083 (scm_gc_async): new variable, points to the GC system-async.
2084 (scm_init_async): save the GC async as scm_gc_async instead
2085 of using system_signal_asyncs.
2086 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2088 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2090 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2091 Don't screw up if we're interrupted.
2092 * Makefile.in: Regeneradet.
2094 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2096 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2098 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2099 we're not using AM_INIT_GUILE_MODULE any more.
2100 * Makefile.in: Reneregated.
2102 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2104 Functions for finding variable bindings, grace à Tim Pierce.
2105 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2106 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2108 Get 'make dist' to work again.
2109 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2110 * Makefile.in: Regenerated, like a surry without a fringe on top.
2112 Changes for reduced Guile distribution: one configure script,
2114 * configure.in, configure: Removed.
2115 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2116 real configure script lives.
2117 * Makefile.in, scmconfig.h.in: Regenerated.
2119 * init.c: #include "script.h", to get prototype for script.c's
2122 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2124 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2125 scm_must_malloc, not raw malloc.
2127 * script.c (scm_compile_shell_switches): Dyke out debugging output
2130 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2132 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2134 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2135 system has them. Hope this is safe. Previously
2136 sys/timeb.h was included if HAVE_FTIME was defined or if
2137 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2138 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2140 * ioext.c (scm_setfileno): add missing third argument to
2141 scm_misc_error call.
2143 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2145 * eq.c (scm_equal_p): Correctly compare strings of different
2146 varieties. (Thanks to Tim Pierce.)
2148 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2150 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2151 #! block comment must occur on a line all by itself.
2153 Move most of the guts of shell command processing into libguile,
2154 so guile.c can be very small (and eventuallly auto-generated. (I
2155 mean, generated mechanically, not self-generated. Hmm.))
2156 * guile.c, script.c, script.h: New source files.
2157 * init.c (scm_boot_guile_1): Call scm_init_script.
2158 * libguile.h: #include "script.h".
2159 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2160 targets, for new executable.
2161 (libguile_la_SOURCES): Mention script.c.
2162 (modinclude_HEADERS): Add script.h.
2163 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2164 not dynamic linking is enabled. This is because we're generating
2165 executables now. Move CY_AC_WITH_THREADS call after those, so the
2166 values of cy_cv_threads_libs captures the libs chosen above.
2167 * Makefile.in, configure, aclocal.m4: Regenerated.
2169 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2170 We don't maintain this interface any more, and it just confuses
2173 * alloca.c: #include <scmconfig.h>, not <config.h>.
2174 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2175 it'll get included in disties.
2177 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2179 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2180 be distributed, because they confuse people.
2181 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2183 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2185 * configure.in: check for presence of gethostent (not present on
2186 OpenBSD by default).
2187 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2188 * configure, scmconfig.h.in: Regenerated.
2190 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2192 * backtrace.c (scm_backtrace): Split message string across
2193 newlines properly. GCC is more tolerant of this than other
2196 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
2198 Merge threads directory into libguile.
2199 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
2200 threads.h: New source files.
2201 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
2202 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2204 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2205 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2206 coop-threads.c.cygnus, coop-threads.h.cygnus.
2207 * configure.in: If we're using threads, include threads.o in
2209 * _scm.h, libguile.h: threads.h lives in this directory now.
2210 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2211 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2212 currently used, but brought along for information's sake.
2213 * ChangeLog-threads: log from old 'threads' directory.
2214 * Makefile.in, configure: Rebuilt.
2216 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2218 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2221 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2223 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2225 Merge GH interface library into libguile.
2226 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
2227 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2228 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2229 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2231 (EXTRA_libguile_la_SOURCES): ... here.
2232 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2233 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2234 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2235 New variables, describing how to build the gh test programs.
2236 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2237 build the test programs, and we probably should have been linking
2238 libguile.la against them all along, to support AIX shared libs.
2239 Add cflags for threads to CFLAGS; add libs for threads to new
2240 variable THREAD_LIBS, used in Makefile.am.
2241 * ChangeLog-gh: log from old `gh' subdirectory.
2242 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2244 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2246 * acconfig.h: Undo change of Apr 9; including the definition of
2247 PACKAGE in the guile headers conflicts with applications' own
2249 * scmconfig.h.in: Regenerated.
2251 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

2255 * filesys.h: Added prototype.
2257 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
2258 when PROC is receiving no arguments.
2260 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2262 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2263 have S_IFSOCK. This is the case under Ultrix.
2265 * posix.c (scm_status_exit_val, scm_status_exit_val,
2266 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2267 Ultrix versions of WIFSTOPPED, etc., which assume that their
2268 arguments are lvalues (hmm).
2270 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2272 * eval.c: Doc fixes.
2274 * throw.c: Doc fixes; rearranged.
2276 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
2278 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
2280 * acconfig.h: Added entry for PACKAGE.
2281 * scmconfig.h.in: Regenerated.
2283 Changes to work with automake-1.1n, which has better libtool support.
2284 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2285 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
2287 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
2289 * Makefile.in: Rebuild.
2291 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2293 * stime.c (scm_mktime): take an optional zone argument.
2294 (scm_localtime): check putenv return value.
2295 (scm_strftime, scm_strptime): moved from posix.c. move #include
2297 stime.h, posix.h: update prototypes.
2298 (bdtime2c, setzone, restorezone): new static procedures.
2299 (scm_mktime, scm_strftime): use them.
2300 (scm_strftime): don't call mktime before strftime. Use
2301 filltime for return value.
2302 (filltime): convert NULL zname to #f.
2303 (scm_strptime): return a count of characters consumed, not
2304 the remaining string.
2306 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2308 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
2309 (scm_mktime): likewise.
2311 Uncomment localtime and mktime.
2313 * configure.in: add AC_STRUCT_TIMEZONE.
2315 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2317 * stime.c (scm_init_stime): don't define ticks/sec.
2318 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2319 return value problem and is still portable.)
2321 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2323 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2324 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2325 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2326 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2327 cpp_err_symbols.c): Corresponding changes.
2328 * Makefile.in: Regenerated.
2330 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2332 * posix.c (scm_putenv): don't check HAVE_PUTENV.
2333 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
2334 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
2335 * putenv.c: new file, from sh-utils 1.12.
2337 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2338 since allocation isn't for Scheme objects.
2339 (scm_putenv): copy strings before placing in the environment.
2341 * stime.c (scm_current_time): throw an error if time returns -1,
2342 instead of returning #f.
2343 (scm_get_internal_real_time, scm_get_internal_real_time): use
2344 scm_long2num for return value instead of SCM_MAKINUM.
2346 * stime.h: prototypes updated.
2348 * stime.c (scm_time_in_msec): apparently unused, deleted.
2350 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2352 * configure.in: check for gettimeofday.
2354 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2355 which may be more usefully portable than a gettimeofday interface.
2357 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2359 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
2361 * Makefile.in: Regenerated.
2363 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2365 * stime.c (filltime): recovered static procedure.
2366 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
2369 * posix.h: add prototype for scm_close_pipe, remove prototypes for
2370 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2372 * posix.c (scm_mknod): split the mode argument into type and perms
2373 arguments, like the extra fields returned by stat.
2375 * fports.c (scm_pipob): set the close, free and print procedures.
2376 (scm_close_pipe): new procedure.
2378 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2379 define them in boot-9.scm
2381 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2383 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
2384 wan't defined. Don't include fd.h.
2386 * Previously fd.h was regenerated whenever configure was run,
2387 forcing a couple of files to be recompiled.
2389 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
2390 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
2391 Check for _fileno as well as _file.
2393 * ioext.c: don't fd.h.
2394 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
2397 * Change the stratigy for getting information about errno
2398 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
2399 generating lists of symbols during the build process, which will
2400 not always work, include comprehensive lists in the distribution.
2401 To help keep the lists up to date, the "check_signals" and
2402 "check_errnos" make targets can be used.
2404 * configure.in: don't check for a command to extract errno codes.
2405 * Makefile.am: update file lists, remove errnos.list and errnos.c
2406 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
2407 check_errnos targets.
2408 (CLEANFILES): remove errnos.c and errnos.list, add
2409 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
2410 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
2411 * errnos.default: deleted.
2412 * cpp_signal.c: new file.
2413 * cpp_errno.c: renamed from errnos_get.c.
2414 * cpp_err_symbols, cpp_sig_symbols: new files.
2415 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
2416 * error.c (scm_init_error): #include cpp_err_symbols instead of
2418 * posix.c (scm_init_posix): don't intern signal symbols. #include
2421 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
2423 * strop.c (scm_i_index): allow the lower bound to be equal to the
2424 length of the string, so a null string doesn't always give an error.
2426 * posix.h: new prototypes.
2427 * posix.c (scm_status_exit_val, scm_status_term_sig,
2428 scm_status_stop_sig): new functions, as in scsh. They break down
2429 process status values as returned by waitpid.
2431 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
2433 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
2434 configure doesn't know about it.
2436 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2438 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
2440 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
2441 which defines C variables with global linkage.
2443 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2445 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
2448 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
2450 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
2451 has time to check why this doesn't work well with continuations.
2453 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
2455 * Fix shell syntax error; some shells won't tolerate
2456 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
2458 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2460 * posix.c (scm_uname): throw an error if uname fails instead
2463 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
2465 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
2468 * async.c (scm_ints_disabled): definition moved from error.c.
2470 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2472 * acconfig.h: Removed PACKAGE.
2474 * scmconfig.h.in: Regenerated.
2476 * snarf.h: g++ says it's non-portable not to specify the first
2477 argument in a varargs declaration. I introduced the first
2478 argument by using preprocessor conditionals.
2480 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
2482 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
2483 (scm_freopen): use RO string macros for filename and modes.
2484 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
2486 * posix.c (scm_getgrgid): simplify conversion of name to C string.
2487 (scm_mknod): use RO string macros for path.
2489 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
2490 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
2492 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2493 use SCM_ROSTRINGP and SCM_ROCHARS.
2495 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2497 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
2500 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
2501 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
2502 support for byte vectors.
2504 * print.c (scm_iprin1): Limit number of vector elements printed
2505 according to pstate->length.
2507 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2509 * backtrace.c (scm_display_error_message): don't segv if message
2512 * error.h: prototype for scm_error_scm.
2514 * error.c (scm_error_scm): new procedure, reimplements scm-error
2515 in C and uses scm_error.
2517 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2519 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
2520 pointer to the Scheme variable read-hash-procedures and intern it
2521 in scm_init_read. Modify scm_read_hash_extend and
2522 scm_get_hash_procedure to use the pointer.
2524 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2526 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
2527 (SCM_KEYWORD_STYLE): defined.
2529 * read.c (scm_read_opts): add a keywords option. This isn't a
2530 boolean option, in case someone wants to add support for DSSSL
2532 Setup scm_keyword_prefix symbol.
2533 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
2535 I've left keyword support disabled by default, since it doesn't
2536 seem to break the module system and it gives R4RS standard behaviour.
2537 It can be reactivated with (read-set! keywords 'prefix).
2539 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2541 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
2542 before constructing arbiter.
2544 * eval.c (scm_m_define): Bugfix: Check that the object is a
2545 closure before setting the procedure property!
2547 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
2549 * ports.c: Removed `ungetc-char-ready?'.
2551 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
2553 * read.c (scm_init_read): intitialise scm_read_hash_procedures
2554 (idea from Mikael: make it a pair so scm_permanent object only
2556 (scm_read_hash_extend): don't call scm_permanent_object.
2557 (ideas from Mikael): if chr is already in the list, replace its
2558 procedure instead of appending it again. If proc is #f, remove
2560 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
2562 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
2564 * gdbint.c (gdb_read): update scm_lreadr usage.
2566 * load.h: update prototypes.
2568 * load.c (scm_primitive_load, scm_read_and_eval_x,
2569 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
2571 * read.h: add prototype for scm_read_hash_extend. Change args for
2574 * read.c (scm_read_hash_procedures): new variable.
2575 (scm_read_hash_extend): new procedure.
2576 (scm_get_hash_procedure): new procedure.
2577 (scm_lreadr): use scm_get_hash_procedure instead of an argument
2578 for extended # processing.
2579 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
2580 scm_read_token): remove case_i, sharp arguments. Change callers.
2582 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
2584 * read.h (SCM_N_READ_OPTIONS): increase to 3.
2585 (SCM_CASE_INSENSITIVE_P): define.
2587 * read.c: add case-insensitive option to scm_read_opts.
2588 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
2589 to determine whether to convert symbol case.
2590 (default_case_i): definition removed.
2591 * read.c (scm_read_token): if case_i, downcase ic before doing
2594 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2596 * configure.in: Added configuration option `guile-debug'.
2597 Configure with --enable-guile-debug if you want a bunch of extra
2598 functions used for debugging when developing Guile.
2600 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
2602 * procs.c (make-cclo): New undocumented debugging procedure: Make
2603 compiled closure with internal procedure PROC and length LENGTH.
2604 Only compiled if GUILE_DEBUG is defined.
2606 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
2608 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
2610 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
2612 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
2613 with 3 or more args internally to the evaluator.
2615 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2617 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
2618 with 3 or more args internally to the evaluator. This is mainly
2619 because we don't want to pass entry and exit points of the
2620 debug support twice, but it also seems to increase the speed of
2621 the evaluator for such calls (e. g. (+ 1 2 3)).
2623 * backtrace.c (scm_display_application): New procedure:
2624 display-application; Set fancy printing parameters individually
2625 for different types of display (backtrace, error, application).
2626 (These should of course be customizable!)
2628 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
2629 clear the CHECK-flags.
2631 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2633 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
2635 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2637 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
2638 from pairs with a GLOC in the car.
2640 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
2641 otherwise `symbol-hash' will behave badly.
2642 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
2643 we get segmentation fault!
2645 * symbols.c: Added #include "weaks.h". New functions:
2646 `builtin-bindings' and `builtin-weak-bindings'. (These will be
2647 moved to an extraneous library when we split libguile.)
2649 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2651 * filesys.c (scm_stat): stat now takes fport arguments too as
2652 documented in the manual.
2654 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2656 * debug.c (scm_single_step): Bugfix: Call continuation with
2657 scm_call_continuation instead of throwing to it.
2659 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
2661 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
2662 argument wasn't declared to be optional.
2664 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2666 * stime.c (scm_init_stime): Add feature "current-time".
2668 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
2670 * throw.h: prototype for scm_exit_status.
2671 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
2672 args to derive an exit status. Allows (quit) to work from a
2674 (scm_exit_status): new function.
2677 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2679 * eval.c (scm_deval): Removed some old code.
2680 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
2682 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
2685 * symbols.c (msymbolize): Bugfix: Must initialize property list to
2688 * procs.c: Introduce the existent C function scm_thunk_p at the
2689 Scheme level as well.
2691 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2693 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
2694 used from C to easily lookup the value of a symbol in the current
2697 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2699 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
2700 scm_init_unif in this file. This will also fix a previous problem
2703 * configure.in: Added AM_MAINTAINER_MODE
2705 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2707 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
2710 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
2712 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
2713 source files that are not always included in libguile but should
2714 have their dependencies calculated by automake. This variable is
2715 recognized by automake, no further magic is needed.
2716 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
2717 to deal exclusively with *.lo files, as it seems. The *.o files
2718 are built automatically when the corresponding *.lo file gets
2721 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
2723 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
2726 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
2728 * unif.c (scm_array_set_x): minor change to argument error checking.
2730 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
2732 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
2733 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
2734 They should only be included in the library at configure.in's
2736 (libguile_la_LDADD): Include the appropriate .lo files here.
2737 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
2738 so we know when to build them (and their .lo bretheren).
2739 * configure.in (LIBLOBJS): New substituted variable. We let
2740 configure decide which .o files to include in LIBOBJS, and then
2741 put the corresponding list of .lo files in LIBLOBJS. The latter
2742 is what we pass to libtool.
2743 * Makefile.in, configure: regenerated.
2745 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
2747 * symbols.c (scm_sysintern0): New function. Contains the core of
2748 old scm_sysintern but doesn't take a second value argument.
2749 (scm_sysintern): Now uses scm_sysintern0.
2750 (scm_sysintern_no_module_lookup): Renamed to
2751 scm_sysintern0_no_module_lookup and doesn't take a second value
2752 argument any longer.
2754 * symbols.h (scm_sysintern0: Added declaration.
2756 * options.c (scm_init_opts): Use scm_sysintern0 instead of
2757 scm_sysintern when interning option keys. Otherwise we risk
2758 destroying the values of already interned variables.
2760 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
2761 scheme-level boolean (use SCM_NFALSEP).
2763 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
2765 (scm_backtrace): New function. (C version of old function from
2766 boot-9.scm) Motivation: Make it possible to display backtraces
2767 without depending on boot-9.scm. (I'm uncertain if this
2768 motivation is good enough...)
2770 * root.h (scm_root_state): Add member the_last_stack_var.
2771 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
2773 * root.c (mark_root): Mark scm_the_last_stack_var.
2775 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
2778 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
2780 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
2781 1. mark_lazy_catch didn't mark the smob.
2782 2. Both functions above have standard variants:
2783 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
2784 free_lazy_catch --> scm_free0.
2786 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
2788 * throw.c (scm_internal_lazy_catch): New function.
2789 (scm_lazy_catch): Rewritten to use it.
2790 (scm_ithrow): Handle the new lazy catch representation.
2791 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
2792 that doesn't have a jmpbuf is a lazy catch clause.
2793 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
2794 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
2795 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
2797 (scm_init_throw): Register the new lazy-catch smob type.
2798 * throw.h (scm_internal_lazy_catch): decl for new function.
2800 * throw.c (scm_internal_catch): Doc fixes.
2802 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
2803 configure.in. Including this might cause problems if applications
2804 that link against libguile include their own copies of alloca, but
2805 if they're using autoconf, they should be adding libguile to LIBS
2806 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
2807 the copy in libguile, and things will be okay. (I think.)
2809 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2811 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
2813 strop.h: move prototypes too.
2815 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2817 * posix.c (scm_init_posix): don't intern EINTR since it's now done
2820 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
2821 etc. I deleted them from filesys.c long ago, but didn't
2822 notice they were here too (although ineffective since
2823 sys/stat.h wasn't included).
2825 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
2827 * eval.c: Don't define alloca in GCC case. gcc will automatically
2828 use __builtin_alloca if appropriate.
2830 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2832 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
2833 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
2834 that values of automatic variables are preserved. See comments
2835 for safe_setjmp for details.
2837 Change from Thomas Morgan:
2838 * variable.c: Include eq.h.
2839 (var_equal): New function.
2840 (variable_smob): Use var_equal as the discriminator for variables.
2842 * throw.c (s_throw): Remove extraneous declaration.
2844 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
2845 * eval.c: Add necessary CPP cruft to support that.
2846 * configure, Makefile.in, scmconfig.h.in: regenerated.
2848 Change from Thomas Morgan:
2849 * procprop.c (scm_procedure_properties): Convert the Scheme
2850 boolean returned by scm_procedure_p into a C boolean before using
2851 it as a condition for SCM_ASSERT.
2852 (scm_procedure_property): Likewise.
2854 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
2855 indications of Unixness.
2858 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2860 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
2862 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2864 * read.c (scm_lreadr): use scm_misc_error to improve one of the
2865 "unknown # object" error messages.
2867 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
2868 (scm_i_index) and declare it static. Add a 'direction' argument
2869 to indicate what way the search should go.
2870 (scm_i_index): throw out-of-range error instead of wrong-type-arg
2872 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
2873 strop.h: remove scm_i_index, scm_i_rindex prototypes.
2875 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2877 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
2879 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
2880 to avoid clash with various scsh forks.
2882 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
2884 The following two changes (ramap.c, throw.c) are motivated by the
2885 apparent unportability of forward declarations of static arrays of
2886 the form `static foo bar[];'.
2888 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
2889 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
2891 * throw.c (scm_throw): Moved above scm_ithrow.
2893 * options.h: Removed the extern declarations of scm_yes_sym and
2894 scm_no_sym since these are static.
2896 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2898 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
2900 * Makefile.am: remove AWK=@AWK@.
2901 Add a rule for generating errnos.list.
2902 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
2904 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
2905 don't extract errnos, just set a variable (avoids the
2906 need to recompile error.c just because configure is run.)
2908 * unif.h: update prototypes.
2909 * unif.c (scm_uniform_array_read,write): change the offset and
2910 length arguments to start and end, for consistency.
2912 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
2914 * ioext.h: update prototypes.
2915 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
2916 scm_read_line_x, it's a more general procedure using an
2917 interface from scsh. read-line and read-line! are now defined
2919 Note that the new read-line trims the terminator
2920 by default, previously it was appended to the returned string. An
2921 optional argument specifies how to process the terminator (scsh
2922 compatible). For the old behaviour: (read-line port 'concat).
2923 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
2924 returns a pair, but is converted to multiple values if the scsh
2927 socket.h: update prototypes.
2928 * socket.c (scm_recvfrom): for consistency with other procedures,
2929 take start and end as separate optional arguments.
2930 (scm_recv, scm_recvfrom): don't allow the second argument
2931 to be a size, only a buffer. Change the scheme names to
2932 recv! and recvfrom!. Don't return the buffer.
2934 * ioext.h, posix.h: move prototypes too.
2935 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
2936 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
2937 "read.h" and "unif.h".
2938 * ioext.c: include "chars.h"
2940 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
2942 * dynl.c: The dynamic linking and module registration functions
2943 are now defined even when dynamic linking is not available for the
2944 host system. Some of their functionality can be done without
2945 dynamic linking; when it's really needed, they throw errors.
2947 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
2949 * configure.in: Only define DYNAMIC_LINKING when one of the system
2950 dependent functions is detected.
2951 * dynl.c (scm_dynamic_func): New function to get the address of a
2952 function in a dynamic object.
2953 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
2954 produced by scm_dynamic_func as the thing to call.
2956 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
2958 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
2959 (scm_register_module_xxx, scm_registered_modules,
2960 scm_clear_registered_modules): New functions.
2962 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
2964 * symbols.c (scm_sysintern): Renamed to
2965 scm_sysintern_no_module_lookup.
2966 (scm_sysintern): New function to take the place of the old
2967 scm_sysintern. It uses the current toplevel lookup closure to give
2968 the symbol its value. This is a temporary hack to put packages
2969 like gtcltk into their own module.
2970 (scm_can_use_top_level_lookup_closure_var): New variable to tell
2971 us whether `scm_top_level_lookup_closure_var' has been initialized
2973 * eval.c (scm_init_eval): Set it.
2975 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
2977 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
2978 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
2980 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
2982 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
2983 scm_sys_dup): deleted: FD capability will be added to other
2985 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
2986 scm_fd_free, fd_smob, scm_intern_fd.
2987 (scm_open): renamed from scm_sys_open. Return a port instead of
2988 an FD object. Make the mode argument optional.
2989 (scm_sys_create): deleted, it's just a special case of open.
2990 (scm_init_filesys): move interning of constants O_CREAT etc.,
2991 here (were previously using SCM_CONST_LONG macro).
2992 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
2994 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
2995 include "fports.h" and <stdio.h>
2996 (scm_stat, scm_select): don't support FD objects.
2998 * error.h: adjust scm_syserror_msg prototype.
2999 * error.c (scm_syserror_msg): take an extra argument for errno.
3000 Using the global value didn't always work, since it could be
3001 reset by procedure calls in the message or args arguments.
3003 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3004 I don't understand why the check was there (and what about the
3007 * strop.c (scm_string_copy): allow shared substrings to be copied.
3009 * unif.h: corresponding change to prototypes.
3010 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3011 recognize two new optional arguments: offset and length. Allow
3012 the port argument to be an integer (file descriptor, for scsh).
3013 Include <unistd.h> for "read" prototype.
3015 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3017 * socket.c: don't include filesys.h.
3019 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3021 * Makefile.am: add AWK=@AWK@ (?)
3023 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3025 Add a rule to generate errnos.c from errnos.
3026 * error.c (scm_init_error): include errnos.c.
3027 * errnos_cnvt.awk: new file, converts the list of errno codes to
3029 * errnos_get.c: new file.
3030 * errnos.default: new file, contains errnos to try if they can't
3031 be extracted from errno.h.
3032 * configure.in: if using GCC, try and extract errno codes from
3036 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3038 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3039 * Makefile.am: Made libguile into a libtool library.
3040 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3041 Set libtool_libs to indicate that libguile is a libtool library.
3042 See guile/ChangeLog for details.
3043 * .cvsignore: ignore "*.lo", the libtool library objects.
3045 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3047 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3048 use htons in getservbyport argument.
3050 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3052 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3053 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3056 * objprop.c (scm_object_property): No need to take the CDR of the
3057 value returned by scm_object_properties, since Aug 20 change.
3059 * configure.in: When checking for struct linger, #include
3060 <sys/types.h> as well as <sys/socket.h>. I've never known
3061 <sys/types.h> to cause any portability problems, and Solaris's
3062 <sys/socket.h> needs it.
3063 * configure: Rebuilt.
3065 I think the Sun compiler has chosen a perverse way to interpret
3066 ANSI declarations combined with K&R definitions. We'll
3067 appease it a little bit. But when it invades France, we fight.
3068 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3069 * print.h (scm_iprlist): Here too.
3070 * numbers.c (scm_divbigdig): Change definition to match
3071 declaration in numbers.h.
3072 * unif.c (scm_makflo): Change definition to match declaration in
3075 * init.c (scm_boot_guile): Don't return the value of
3076 scm_boot_guile_1. This function doesn't return a value;
3077 scm_boot_guile_1 doesn't return a value (or return at all).
3079 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3082 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3083 compile. I have a feeling this function is a bad idea anyway ---
3084 one should always test for features, not systems.
3086 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3087 semicolons. Only pure luck kept this from being noticed earlier.
3089 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3091 * socket.c (scm_recvfrom): Added missing semicolon.
3093 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3095 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3096 the buffer and start and end positions for scsh networking
3099 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3101 * configure.in: Revert previous change to this file; the problem
3102 is due to transient automake weirdness.
3103 * configure: Rebuilt.
3105 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3106 PLUGIN/guile.libs. configure generates the latter from the former.
3107 * Makefile.in: Rebuilt.
3109 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3110 need this if we install scripts, like guile-snarf.
3111 * configure: Rebuilt.
3113 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3115 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3117 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3119 * socket.c (scm_addr_vector): fix faulty scm_listify.
3121 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3123 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3124 style block comment is no longer considered an error.
3126 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3128 * PLUGIN/guile.libs.in: New file.
3129 * PLUGIN/guile.libs: Removed from repository.
3130 * configure.in: Create PLUGIN/guile.libs from
3131 PLUGIN/guile.libs.in. This is for including additonal libraries
3132 needed for dynamic linking.
3133 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3134 instead of PLUGIN/guile.libs.
3136 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3138 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3140 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3141 occurrences of the given element from the list, not just the
3142 first. This is how the Emacs Lisp functions behave, how the
3143 analogous Common Lisp functions behave, and (I believe) how the
3144 older Maclisp functions worked. I realize that this change may
3145 break code, but it seemed better to break it before the Guile
3148 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3149 Their prototypes were already present in gc.h, but they weren't
3151 (scm_init_storage): Initialize scm_protects.
3152 * root.c (scm_protects): New element of scm_sys_protects.
3154 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3156 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3158 * libguile.h: Added #include "libguile/net_db.h".
3160 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3161 30 change. That file is only meant for communication between the
3162 configuration process and load.c. If code linked against libguile
3163 wants to get at the paths mentioned in libpath.h, it can call
3164 functions declared in load.h.
3166 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3168 * libguile.h: Removed #include "libguile/fdsocket.h"
3170 * net_db.c: Added #include <sys/socket.h>.
3172 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3174 * filesys.c (scm_input_waiting_p): use select in preference to
3175 FIONREAD, since the latter doesn't detect EOF.
3176 Throw error if neither select nor FIONREAD available.
3178 * socket.c (scm_connect): take a port, not a fd object.
3179 (scm_fill_sockaddr): throw an error if fam is not recognised.
3180 (scm_bind): use scm_fill_sockaddr.
3181 (scm_listen): take a port, not a fd object.
3182 (scm_accept): take and return a port. return #f in the car if
3183 address can't be got
3184 (scm_sock_fd_to_port): new procedure.
3185 (scm_socket): use scm_sock_fd_to_port.
3186 (scm_addr_vector): throw error if unrecognised address type.
3187 take an extra argument with the calling procedure name.
3188 (scm_getsockname): take a port. return #f if address can't be got.
3189 (scm_getpeername): take a port. return #f if address can't be got.
3190 (scm_recvfrom): take a port. return #f for address component if can't
3192 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3193 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3195 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3197 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3198 use separate data pointers, to allow them to be designed
3199 independently and reused.
3200 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3201 Renamed from catch_body, catch_handler, and uncaught_throw; made
3203 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3205 (scm_catch): Use the above.
3206 (scm_throw): Don't bother printing a message for an uncaught
3207 throw; we establish a default handler in init.
3208 * throw.h (scm_internal_catch): Prototype updated.
3209 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3211 (struct scm_body_thunk_data): New structure, used as data
3212 argument to scm_body_thunk.
3213 * init.c (struct main_func_closure): New structure, packaging up
3214 the data to pass to the user's main function.
3215 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3216 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3217 scm_internal_catch to establish a catch-all handler, using
3218 scm_handle_by_message. This replaces the special-case code in
3220 (invoke_main_func): Body function for scm_internal_catch; invoke
3221 the user's main function, using the main_func_closure pointer to
3222 decide what to pass it.
3223 * root.c (struct cwdr_body_data): Remove handler_proc member.
3224 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3225 (cwdr_handler): Removed.
3227 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3229 * socket.h (SCM_P): update bind prototype.
3230 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3231 include "feature.h".
3232 (scm_socket): return a port, not a file descriptor object.
3233 include "fports.h" and <unistd.h>
3234 (scm_bind): take a port, not a file descriptor object.
3235 take an extra argument for address args.
3237 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3238 INADDR_NONE, INADDR_LOOPBACK.
3240 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3242 * init.c: include net_db.h and not fdsocket.h.
3243 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3245 * Makefile.am: corresponding changes.
3246 * socket.h: renamed from fdsocket.h, fix names.
3247 * net_db.h: renamed from socket.h, fix names.
3248 * socket.c: renamed from fdsocket.c.
3249 remove _sys from procedure names.
3250 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3251 add "socket" to features list.
3252 * net_db.c: renamed from socket.c.
3253 remove _sys from procedure names.
3254 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3255 add "net-db" to features list.
3256 include "net_db.h". don't include <sys/socket.h> or
3259 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3261 * tags.h (scm_tags): Removed comma at end of last enumerator.
3263 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3265 Don't use GCC extensions to allocate space for debugging frames.
3266 (Here he goes again! Why do we put up with this?!)
3267 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3268 an scm_debug_info structure, not an in-line array of them. Add
3269 'info' member, to say how many vect elements we've used, for eval
3271 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3272 a new variable debug_info_end to mark the end of vect, instead of
3273 the address of the 'info' pointer itself.
3274 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3275 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3276 (SCM_APPLY): Explicitly allocate space for debug.vect.
3277 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3278 * stacks.c: Adjusted for new debug frame structure.
3279 (RELOC_INFO, RELOC_FRAME): New macros.
3280 (stack_depth, read_frames): Use them, and new scm_debug_frame
3281 element 'info', instead of magically knowing that eval frames have
3282 an info pointer sitting after vect.
3283 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3285 (scm_init_stacks): Formatting tweaks.
3287 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3289 Give GCC more control flow information, so it can be sure that
3290 variables aren't used uninitialized.
3291 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3292 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3293 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3294 scm_misc_error): Tell GCC that these functions never return.
3295 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3296 out the field type, call abort if SCM_ASSERT returns, to placate
3298 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3299 scm_wta ever returns. We can't handle this case anyway, and this
3300 gives the optimizer more information.
3301 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3302 scm_wta ever returns.
3304 In some cases, the code is fine, but GCC isn't smart enough to
3305 figure that out; this usually happens when one variable is only
3306 initialized and used when a particular condition holds true, and
3307 we know that condition will never change within a given invocation
3308 of the function. In this case, we simply initialize the variables
3309 to placate the compiler, hopefully to a value which will cause a
3310 crash if it is ever actually used.
3311 * print.c (scm_iprin1): Initialize mw_pos.
3312 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3313 * throw.c (scm_ithrow): Initialize dynpair.
3314 * unif.c (scm_uniform_vector_ref): Initialize cra.
3315 * struct.c (init_struct): Initialize prot.
3316 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3318 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3319 if EXPR contains no expressions.
3321 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3323 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3324 cause an infinite loop (???). So much for the algebraic
3325 equivalency of variable-sized arrays and alloca...
3327 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3329 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3330 a SCM boolean, not a C boolean.
3332 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3334 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3335 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3336 rules for raising scm_mtrigger. Previously, unfortunate but not
3337 unlikely circumstances could result in almost constant invokation
3338 of the gc. Now, this situations should be less likely, but they
3339 are not prevented completely.
3341 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3343 * numbers.c (scm_fuck): Procedure removed; looks like old test
3345 * numbers.h: Prototype removed.
3347 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3349 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3350 array to a pointer, to match my Nov 21 change in eval.c.
3352 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3354 * libguile.h: Added #include "libguile/backtrace.h", #include
3355 "libguile/stacks.h".
3357 * strings.c (scm_string scm_make_string scm_string_ref
3358 scm_string_set_x scm_string_equal_p scm_string_append):
3359 Bugfix according to scm patch from Aubrey Jaffer:
3360 Corrected long-standing
3361 (not (eqv? (integer->char 128)
3362 (string-ref (make-string 1 (integer->char 128)) 0)))
3363 bug found by John Kozak <jk@noontide.demon.co.uk>.
3365 * strports.c, strports.h: Make scm_eval_0str return the value of
3366 the last expression evaluated (previously, it returned void).
3368 * strports.c, strports.h: New function: scm_read_0str. Does what
3371 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3373 * simpos.c (scm_getenv): return #f if string can't be found in the
3374 environment instead of throwing an exception, for compatibility
3375 with numerous other systems.
3377 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3379 * Makefile.am (.c.x): Use guile-snarf.
3380 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
3382 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
3384 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3386 * backtrace.c (scm_display_error_message): Made non-static, and
3387 renamed from display_error_message.
3388 * backtrace.h (scm_display_error_message): Added extern decl.
3389 * throw.c (uncaught_throw): Use it to display the error message.
3391 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
3393 * inet_aton.c: Use #if 0, not #ifdef 0.
3395 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
3397 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
3398 to convert the returned value.
3399 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
3400 the offset argument.
3402 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3404 Add new interface to catch/throw, usable from C as well as
3406 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
3407 (scm_internal_catch): New function, replaces...
3408 (scm_catch_apply): Deleted.
3409 * throw.c (scm_catch_apply): Deleted; replaced with a more general
3410 mechanism which is a bit more code, but can be used nicely from C
3411 and implement the Scheme semantics as well.
3412 (scm_internal_catch): This is the replacement; it's named after
3413 the analogous function in Emacs.
3414 (scm_catch): Reimplemented in terms of the above.
3415 (struct catch_body_data, catch_body, catch_handler): New
3416 functions, used by scm_catch.
3417 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
3418 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
3419 support for new cwdr.
3421 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
3424 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
3426 * acconfig.h: Added DYNAMIC_LINKING symbol.
3427 * configure.in: Add option and checks for dynamic linking.
3428 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
3429 dynl.h: New files for dynamic linking support.
3430 * Makefile.am (libguile_a_SOURCES):
3432 (modinclude_HEADERS): Added "dynl.h".
3433 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
3435 * init.c (scm_boot_guile_1): Call
3436 scm_init_dynamic_linking to initialize dynamic linking support.
3438 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
3440 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
3441 (as we Schemers say). It needs to be global, so that I can tweak
3442 it for the proper operation of unexec.
3443 (scm_boot_guile_1_live): New variable, see above.
3445 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
3447 * guile-snarf.sh: Removed.
3448 * PLUGIN/guile.libs: Added dependency for -lm.
3449 * acinclude.m4: Renamed from aclocal.m4.
3450 * PLUGIN/greet: Removed.
3451 * Makefile.am, aclocal.m4: New files.
3452 * configure.in: Updated for Automake.
3454 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
3456 * eval.c (scm_definedp): Use top_level_lookup_closure_var
3457 and not top_level_lookup_thunk_var.
3459 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
3461 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
3463 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
3465 * eval.c (scm_definedp): Incompatibly changed to be a builtin
3466 Scheme function, instead of syntax. Single argument is now a
3469 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3471 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
3472 scm_ra_divide): Properly terminate statements passed as arguments
3473 to IVDEP macros. (Thanks to Bernard Urban.)
3475 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
3476 with non-constant sizes. (Thanks to Bernard Urban.)
3478 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3480 It's an "eval closure", not an "eval thunk." A thunk is a
3481 function of no arguments.
3482 * root.h (struct scm_root_state): Renamed
3483 top_level_lookup_closure_var from top_level_lookup_thunk_var.
3484 (scm_top_level_lookup_closure_var): Renamed from
3485 scm_top_level_lookup_thunk_var.
3486 * root.c (mark_root): Uses changed.
3487 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
3488 * init.c (scm_start_stack): Uses changed.
3489 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
3490 Change scheme-visible name to *top-level-lookup-closure* from
3491 *top-level-lookup-thunk*.
3493 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
3495 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
3496 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
3498 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
3500 * gc.c (struct scm_heap_seg_data): Doc fixes.
3502 * gc.c (scm_gc_sweep): Empty all segments' freelists before
3503 sweeping. Then, prepend each segment's free cells to its
3504 freelist, rather than wiping out the old value. (Thanks to Marius
3507 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
3508 scm_check_freelist, scm_debug_newcell): New functions and
3509 variables, for debugging freelist problems.
3510 * pairs.h (SCM_NEWCELL): New debugging version added.
3511 * gc.h (scm_debug_newcell): Added extern declaration, used by
3512 debugging version of SCM_NEWCELL.
3514 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3516 On some systems <libc.h> conflicts with <unistd.h>, and should not
3517 be #included at all.
3518 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
3519 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
3520 * configure.in: Call it.
3521 * posix.c, filesys.c: Use its results to decide whether or not to
3523 * configure, scmconfig.h.in: Rebuilt with autoconf and
3526 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
3528 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
3529 pointer to the stdio stream before calling scm_setbuf0, so the
3530 latter will be able to retrieve it. I'm surprised this didn't
3531 segfault earlier. (Thanks to Christopher Lee.)
3533 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3535 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
3538 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3540 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
3541 number of stack narrowing specifier pairs. The first specifier in
3542 a pair controls inner border, the second the outer border. A
3543 number means cut that number of frames, a procedure object means
3544 cut until that object is found in operator position in a frame.
3546 * root.c (cwdr): Bugfix.
3548 * read.c: Recording of positions disabled by default.
3550 * procs.c (scm_closure_p): New function.
3552 * posix.c (scm_tmpnam): New function.
3554 * load.c: Added #include "throw.h".
3555 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
3558 * load.c, load.h (scm_read_and_eval_x): New function.
3560 * eval.c: Renamed debug option "deval" to "debug".
3562 (scm_eval_x): `eval!' is no longer accessible from the scheme
3563 level. Motivation: We can't allow operations which introduce
3564 glocs into the scheme level. Guile's type system can't handle
3565 these as data. Use `eval' or `read-and-eval!' as replacement.
3567 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
3568 SCM_CONSP since this is a macro!; Set vframe.prev to
3569 scm_last_debug_frame instead of 0. In this way we can look
3570 "above" the virtual start stack frame if we wish.
3571 (scm_debug_hang): New function: Useful for debugging Guile in
3572 certain tricky situations. Will probably be removed later...
3574 * debug.h: Changed semantics of debug option "backtrace". This
3575 option now only indicates whether we want automatic backtrace at
3578 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3580 * ports.c: #include "filesys.h"
3581 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
3583 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
3584 Motivation: This is system specific code which is related to file
3585 I/O. It also may use select. Added code by Gary Houston to
3586 detect presence of character in stdio buffers.
3588 * libguile.h: #include "libguile/libpath.h"
3590 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
3591 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
3592 SCM_SITE_DIR; Install libpath.h among the other include files.
3594 * load.c, load.h (scm_sys_package_data_dir): New function.
3596 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3598 * stacks.h: Bugfix: Don't use tail-array length field as stack
3599 length field! This screwed GC.
3601 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3603 * _scm.h: Added #ifndef around definition of macros min and max.
3605 * __scm.h: Added hooks for threads to plugin to in ints protection
3606 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
3607 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
3608 the main code in these macros duplicated and spread over multiple
3609 files. Renamed SCM_THREADS_SWITCHING_CODE ->
3610 SCM_THREAD_SWITCHING_CODE.
3612 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
3614 * snarf.h: New file.
3615 * guile-snarf.sh: New file.
3616 * Makefile.in (inner_h_files): Added snarf.h
3617 (ancillary, install, uninstall, distclean): Added actions for
3619 (.c.x): Use guile-snarf.
3620 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
3621 (gen_c_files): Note that these depend on guile-snarf.
3622 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
3623 now in "snarf.h". Added #include "snarf.h" to get them.
3624 * libguile.h: Added #include "snarf.h".
3625 (Patches applied and tweaked by Jim Blandy.)
3627 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
3629 * socket.c: Use K&R style declaration for 'close'; the GNU coding
3630 standards suggest against providing prototypes for system
3631 functions. Thanks to Greg Troxel.
3633 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3635 * strports.c (scm_eval_0str): New function.
3636 #include "read.h", to get prototype for scm_read.
3637 * Makefile.in (strports.o): Update dependencies.
3638 * strports.h: New prototype.
3640 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
3641 scheme name from "int?" to "integer?". It seems to do the job.
3642 * numbers.h: Rename prototype too.
3643 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
3646 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
3647 scm_num_eq_p): Rename these according to R4RS conventions: call
3648 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
3649 to making libguile R4RS compliant without ice-9...
3651 * load.c (scm_sys_search_load_path): Search for files under all
3652 extensions listed in the %load-extensions variable. If FILENAME
3653 is absolute, return it unchanged, without searching the load path.
3654 (scm_loc_load_extensions): New variable, pointing to
3655 %load-extensions' value cell.
3656 (scm_init_load): Initialize it, and the value it points to.
3657 (scm_primitive_load_path): Improve error reporting.
3659 * load.c (scm_loc_load_hook): New variable, pointing to value cell
3660 of new Scheme variable %load-hook.
3661 (scm_primitive_load): Apply %load-hook to filename.
3663 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
3665 * configure.in: add tests for figuring out whether buffered data
3666 is available in a FILE structure, which is needed by char-ready.
3668 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
3671 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
3672 exceptions using misc_error instead of syserror. It seems a bit
3673 odd to throw an exception if a string can't be found in the
3674 environment, but it's consistent with open-file, stat etc.
3675 (simpos.h): remove sys_ from getenv.
3677 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
3678 occurs, throw an error instead of returning errno. Return value
3680 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
3682 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
3684 * filesys.c (scm_stat2scm): derive file type and permissions from
3685 the stat mode and append them to the returned vector.
3686 There isn't much overhead in doing this and it avoids the need to
3687 work with S_IRUSR et al. in Scheme.
3688 Define symbols scm_sym_regular etc.
3689 (scm_init_filesys): don't intern S_IRUSR etc.
3691 * load.c: change s_try_load and s_try_load_path to s_primitive_load
3692 and s_primitive_load_path.
3694 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
3696 * error.h: don't declare error symbols. prototype for scm_misc_error.
3698 * stackchk.c (scm_stack_overflow_key): defined here instead of in
3701 * error.c: use SCM_SYMBOL to set up error keys.
3702 scm_misc_error: new procedure.
3704 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3706 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
3707 between `#!' and `!#' is ignored.
3708 (skip_scsh_block_comment): New function.
3710 * feature.c (scm_set_program_arguments): New argument, FIRST.
3711 * feature.h: Update prototype.
3712 * init.c (scm_boot_guile_1): Pass new argument to
3713 scm_set_program_arguments.
3715 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3717 * init.c (scm_start_stack): Don't initialize scm_progargs here.
3718 (scm_boot_guile): Call scm_set_program_arguments here, later than
3719 the old initialization.
3721 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
3722 initialization procedure.
3723 - Delete in, out, err arguments; there are other perfectly good
3724 ways to override these when desired.
3725 - Delete result argument; this function shouldn't ever return.
3726 - Rename init_func argument to main_func, for less confusion.
3727 - Delete boot_cmd argument; main_func is more general.
3728 -Add 'closure' argument, to help people pass data to main_func
3729 without resorting to global variables.
3730 - Abort if reentered; don't bother returning an error code.
3731 - Call scm_init_standard_ports to set up the default/current
3732 standard ports; no need to pass them to scm_start_stack.
3733 - Remove code to evaluate the boot_cmd, and start the repl; let
3734 the user do something like that in main_func if they want.
3735 - Remove code to package up a return value; main_func can do any
3737 - Call exit (0), instead of returning.
3738 (scm_start_stack): Don't initialize the I/O ports here; that's
3739 weird. Delete in, out, err arguments. Move guts to
3740 scm_init_standard_ports, scm_stdio_to_port.
3741 (scm_init_standard_ports): New function, to set up current and
3742 default standard ports.
3743 (scm_start_stack, scm_restart_stack): Make these static.
3744 * init.h (scm_boot_guile): Adjust declaration.
3745 (scm_start_stack, scm_restart_stack): Remove externally
3746 visible declarations for these.
3747 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
3749 * fports.c (scm_stdio_to_port): New function. Its guts used to be
3750 written out several times in scm_start_stack.
3751 * fports.h: New declaration for the above.
3753 * feature.c (scm_set_program_arguments): New function.
3754 * feature.h: New declaration for the above.
3756 * ports.c: Formatting tweak.
3758 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
3760 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
3761 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
3762 for obtaining the address of a car or cdr field. Motivation:
3763 &SCM_CXR make assumptions about the internal structure of the
3766 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
3767 Motivation: see SCM_CXRLOC.
3769 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
3770 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
3771 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
3772 Motivation: Safer use. Some other macros are defined in terms of
3773 these operations. If these are defined using the SCM_SETCXR
3774 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
3775 to inefficiency and an <e1> with side-effects could potentially
3776 break. Also, these particular operations are heavily utilized in
3777 the garbage collector. In unoptimized code there will be a
3780 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
3781 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
3782 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
3783 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
3784 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
3785 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
3786 vports.c: Cleaned up use of pairs: Don't make any special
3787 assumptions about the internal structure of selectors and
3788 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
3789 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
3790 (Among other things, this change makes it easier to build Guile
3791 with certain compilers which have problems with casted lvalues.)
3793 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3795 * stacks.c: Improve selection of relevant stack frames when making
3796 a stack object. Introduce one level of indirection in the stack
3797 object to make it possible to "narrow" to a certain region of the
3798 stack. This facilitates making use of more clever algorithms (not
3799 implemented) for selecting relevant frames and gives a cleaner
3800 design since selection of frames can be done independently of
3801 extraction of frames from the real stack.
3802 (scm_stack_id): Also take #t as argument which means look at
3805 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
3806 Turn n_tail into an integer directly representing current number
3807 of frames in stack. Add field tail.
3809 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
3811 * debug.c (scm_make_memoized): Made it available at scheme level.
3812 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
3813 SCM_NIMP before applying heavier predicates in argument checking.
3814 (scm_local_eval): Also take memoized object as argument.
3816 * backtrace.c (scm_display_error): Just a safety measure: Stacks
3817 aren't created with zero length, but should such a strange
3818 creature suddenly turn up...
3820 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
3822 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
3823 `del', for the sake of C++ compilers. (Patch applied by JimB.)
3825 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
3827 * variable.c (scm_make_variable): Make the name hint optional, as
3829 (anonymous_variable_sym): Renamed from variable_sym. All uses
3832 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
3833 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
3834 of scm_primitive_load_path was also changed to
3835 "primitive-load-path", from "%try-load-path". Callers changed.
3836 We'd like to respect the convention that a function named
3837 "try-mumble" should behave just like the function called "mumble",
3838 but return #f instead of signalling some error.
3839 * load.h: Rename prototypes.
3841 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3843 * print.c (make_print_state, grow_print_state), print.h: Modified
3844 the print state representation: Don't use a tail array for
3845 recording of circular references. Resizing of the print state
3846 structure invalidates the print state pointer. To avoid passing
3847 around an indirect print state reference to all printing
3848 functions, we instead let the print state reference a resizable
3851 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
3853 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
3854 Don't crash when passed an improper list terminated by a
3855 non-immediate value.

3859 Allocate data for structures on an eight-byte boundary, as
3860 required by the tagging system.
3861 * struct.c (alloc_struct): New function.
3862 (scm_make_struct, scm_make_vtable_vtable): Call it.
3863 * struct.h (scm_struct_n_extra_words): Bump to 3.
3864 (scm_struct_i_ptr): New "field".
3865 * gc.c (scm_gc_sweep): When we need to free the data, use the
3866 information stored by alloc_struct to find the beginning of the
3867 block allocated to the structure, so we can free it.
3869 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3871 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
3874 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
3875 (scm_debug_info): New member: id.
3877 * stacks.c: Stacks are now represented as structs; Stacks have an
3878 id given to them by `start-stack'.
3879 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
3881 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
3882 Changed stack representation.
3884 * debug.c (scm_procedure_name): Try procedure property `name' for
3885 compiled closures aswell.

3893 * procprop.h: Added declaration of scm_i_name.
3895 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
3896 (scm_make_gsubr): Record names of compiled closures.
3898 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>

3902 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
3903 stacks.c: Renamed regs --> scm_contregs.
3905 * print.c (scm_free_print_state): Cleanup print state before
3906 returning it to pool. It is better to do it here than in
3907 scm_prin1 since scm_prin1 is called often.
3909 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
3910 s_set_source_property_x): Check that first argument is a pair or a
3913 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
3914 scm_i_line, scm_i_column and scm_i_breakpoint global.
3916 * init.c: Added #include "backtrace.h" and #include "stacks.h".

3929 * symbols.c (scm_sym2ovcell): Fixed documentation.
3931 * _scm.h (min, max): Added.
3933 * async.c: Moved `min' macro to _scm.h.
3935 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
3936 SCM_BACKTRACE_INDENT.

3948 scm_free_print_state.
3950 * debug.c (scm_m_start_stack): New acro.
3952 * debug.h: Small cleanup.

3977 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
3978 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
3979 declare functions with prototypes. (Patch thanks to Marius
3982 More prototype-related changes from Marius Vollmer:
3983 * gdb_interface.h: Wrapped header file in #ifdef/#endif
3984 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
3985 * ports.h (ptobfuns): Added prototypes. This means some casting in
3987 * fports.c: Added casts for initializations, since the functions
3988 are defined to take FILE * as their stream argument, not SCM.
3989 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
3990 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
3991 to `char *str_data' to conform to prototype.
3993 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
3995 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
3997 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
3999 * stime.c, stime.h: use SCM_P method.
4001 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4003 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4004 be given at least two arguments. Insist that lst's last element
4005 be a list, but don't make any requirements of its predecessors.
4007 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4009 * eval.c (scm_nconc2last): Revert last change; there seems to be
4010 other stuff going on here.
4012 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4014 * eval.c (scm_nconc2last): Make sure that each element of lst
4015 (which is a list of argument lists, except for the tail) is a
4016 proper list, i.e., finite and terminated by '().
4018 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4020 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4023 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4024 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4027 * vectors.c (scm_make_vector): Fill vectors with the undefined
4028 value, to help make Guile Scheme code more portable to other
4031 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4032 * symbols.h, tags.h: Doc fixes.
4034 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4036 * async.c (scm_take_signal): Doc fixes.
4038 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4040 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4041 want to subtract it from the modulus; we just want to leave it
4044 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4046 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4049 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4051 * throw.c (scm_catch_apply): Finished implementation of
4054 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4056 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn

4061 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4063 * Makefile.in (root.o): Correct dependencies.
4065 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4067 * Makefile.in: Added dependency entry for root.o.
4069 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4070 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4072 * init.c (scm_start_stack): Set initial root continuation number
4075 * procs.c: New function: scm_thunk_p.
4077 * procs.h: Added declarations of scm_thunk_p.
4079 * root.c: Renamed `call-with-new-root' -->
4080 `call-with-dynamic-root'.
4081 (cwdr): Removed allocation of new root state. This should be done
4082 separately by use of scm_make_root.
4083 (scm_apply_with_dynamic_root): New function: Does what it
4084 sounds like. Needed when spawning threads.
4086 * root.h: Added member last_debug_frame to root state.
4087 Added #include "libguile/debug.h"
4089 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4090 arguments. The motivation is that code in root.c needs catch
4091 functionality, and we want to avoid code duplication.
4092 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4093 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4094 handlers that run without popping the stack into the dynwind
4097 * throw.h: Added prototypes for scm_catch_apply and
4100 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4102 * root.h (scm_root, scm_set_root): Decouple thread support details
4103 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4104 SCM_SET_THREAD_LOCAL_DATA.
4106 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4107 and tortoise scanning loop.
4109 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4111 * Makefile.in: Rebuild dependencies.
4113 * libguile.h: #include "libguile/print.h" before "smob.h", since
4114 the latter uses the print_state structure.
4116 * throw.c (scm_ithrow): Use the correct variable when checking to
4117 see if a given element of scm_dynwinds is a valid catch.
4119 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4120 structure, abort; don't just silently ignore the garbage.
4122 * _scm.h: #include "print.h" here, since it seems to be used just
4124 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4125 strports.c, unif.h: Don't #include "print.h".
4127 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4129 * feature.h (scm_loc_features): Removed external declaration.
4130 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4132 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4134 * feature.c (scm_init_feature): Added threads feature (needs to be
4135 initialized here, since features doesn't exist when
4136 scm_init_threads is called).
4138 * libguile.h: Added #include "libguile/../threads/threads.h".
4139 (This is a kludge to get thread support working. This should be
4142 * configure.in, acconfig.h: Added flags for thread support.
4144 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4147 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4148 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4151 * _scm.h: Added conditional #include "threads.h"
4153 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4154 SCM_THREADS_SWITCHING_CODE.
4156 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4157 allocate the basic dynamic root object.
4158 (scm_boot_guile): Added call to scm_init_root.
4160 * root.c, root.h: Added root smob.
4161 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4162 functions: Implements dynamic roots mostly according to spec in
4163 SCM manual. Main difference is that the second argument is a
4164 throw handler rather than an error "thunk".
4166 * root.h: Added declaration of scm_init_root.
4168 * root.c: Added #include "genio.h", #include "smob.h", #include
4169 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4171 (scm_init_root): Added #include "root.x".
4173 * throw.c: Added #include "stackchk.h"
4174 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4175 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4176 can be used in scm_call_with_new_root; Added reenabling of stack
4177 checking when catching a throw.
4179 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4181 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4183 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4184 element is not found, as per R4RS.
4186 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4188 * list.c: Doc fixes throughout.
4190 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4192 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4193 declare the char * to be const. Avoids a warning in rgx.c.
4195 * ports.h: spelling fix.
4197 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4200 * load.c (scm_sys_try_load_path): throw an error if file not found
4201 (like it says it in NEWS).
4203 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4205 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4206 PROPS slot to '(), not #f; it's an empty alist.
4208 * throw.h, throw.c: Use SCM_P instead of #if hair.
4210 Remove special support for uncaught throws; see throw.c for
4212 * throw.c (uncaught_throw): New function.
4213 (scm_ithrow): Call uncaught_throw if we don't find a throw
4214 target; don't mess with scm_bad_throw_vcell.
4215 (scm_bad_throw_vcell): Variable deleted.
4216 (scm_init_throw): Don't initialize it.
4218 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4221 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4223 * numbers.c (scm_istr2int): If the number is short (as most
4224 numbers are), just call scm_small_istr2int to deal with it.
4225 (scm_small_istr2int): New function, created by un-#ifdefing the
4226 non-bignum version of scm_istr2int and renaming it.
4228 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4230 * load.c (scm_sys_try_load): don't check whether value returned
4231 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4232 Change the Scheme name from %try-load to primitive-load.
4234 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4235 Can avoid passing a message, allowing it to be derived in the
4236 error handler (e.g., if we want to throw to the key both from
4239 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4241 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4242 references now have a new appearance which is more compact and
4243 also gives a clue about what the target of the reference is.
4244 By setting parameters in the print state, more fancy printing can
4245 be achieved. This is used by the (not yet commited) backtrace
4248 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4250 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4253 * print.c: Added #include "struct.h". Removed function
4256 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4257 scm_iprin1. Removed prototype for scm_prlist.
4259 * arbiters.c (prinarb),
4260 async.c (print_async),
4261 debug.c (prindebugobj, prinmemoized),
4262 eval.c (prinprom, prinmacro),
4263 filesys.c (scm_fd_print, scm_dir_print),
4265 mallocs.c (prinmalloc),
4266 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4267 smob.h (scm_smobfuns),
4268 srcprop.c (prinsrcprops),
4270 unif.c, unif.h (scm_raprin1, rapr1),
4271 variable.c (prin_var): Changed argument `int writing' to
4272 `scm_print_state *pstate'.
4274 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4275 that it will be called before scm_init_print.
4277 * print.c (scm_prin1): Print states are now allocated when calling
4278 scm_prin1 and then passed around to all printing functions as an
4279 argument. A cache `print_state_pool' enables reuse of print
4281 (scm_make_print_state): New function.
4282 (scm_iprin1): Adaption to print states.
4283 (scm_iprlist): An initial "hare and tortoise" scan brings down
4284 time complexity to O (depth * N). (Better time complexity will be
4285 achieved when the printing code is completely rewritten.)
4287 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4289 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4290 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4291 it gets done whether or not the cache variable has a value.
4293 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4295 Distinguish #f and ().
4296 * __scm.h: #undef SICP.
4297 * pairs.h (SCM_EOL): Delete this definition, equating it with
4299 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4300 the value it used to have. Doc fixes, too.
4302 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4304 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4305 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4306 Lord's implementation of structs, allowing for tail arrays as
4307 described in the manual. Also fixed some bugs. (Both the interface
4308 and the implementation should be improved.)
4310 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4312 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4313 People who whish to see the source can do `(print-enable 'source)'.
4314 Removed #ifdef DEBUG_EXTENSIONS.
4316 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4318 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4319 integer (assuming for now accepting an integer is a good thing).
4321 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4322 %S will be used instead for write'ing arguments.
4324 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4325 asserts. fix a few other asserts.
4326 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4327 scm_uniform_vector_ref, scm_array_set_x,
4328 scm_dimensions_to_unform_array): change args in
4329 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4330 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4331 scm_substring_fill_x): likewise.
4332 gsubr.c (scm_gsubr_apply): likewise.
4333 eval.c (SCM_APPLY): likewise.
4335 * eval.c (4 places): replace scm_everr with lgh_error or
4338 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4339 scm_memory_error): new procedures.
4340 scm_everr: deleted. can use scm_wta, dropping first two args.
4341 scm_error: convert NULL subr to SCM_BOOL_F.
4343 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4346 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4349 * error.c, error.h: new error keys: scm_arg_type_key,
4350 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4352 scm_wta: reimplement using lgh_error instead of scm_everr.
4354 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4356 * gdbint.c: scm_lread now has one more argument.
4358 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4359 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4360 loading source from non-file ports, which, e. g., happens when
4361 using the Emacs interface).
4363 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4366 * read.c: Added code for recording of positions of source code
4367 expressions; New functions: recsexpr, scm_lreadrecparen;
4368 _scm_make_srcprops --> scm_make_srcprops
4369 (scm_flush_ws): Removed updating of positions counters. This work
4370 is already done by scm_gen_getc
4372 * read.h: Added prototype for scm_lreadrecparen
4374 * print.c: Added #include "alist.h"
4376 * eval.c: Added #include "hash.h"
4378 * eq.c: Added #include "ramap.h"
4380 * options.c: Documentation fixes.
4382 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
4383 (scm_init_srcprop): Adjusted size of initial source-whash. Name
4384 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
4385 --> scm_make_srcprops
4387 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
4388 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
4389 function calls in the definition of the whash access macros.
4391 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
4393 * init.c (scm_boot_guile): Add level of indirection to
4394 scm_boot_guile_1() to ensure that stack base pointer is properly
4395 initialized. There was no guarantee that variable i was the
4396 highest/lowest variable on stack (i.e. the call frame of
4397 scm_boot_guile was not completely protected from gc).
4399 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
4401 * ports.h (scm_port_table): put back file_name, it will be used to
4402 support debugging. Undo related changes in fports.c, ioext.c,
4405 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4407 * ports.h (scm_port_table): remove file_name member for now, it seems
4409 * fports.c (scm_open_file): don't set file_name in PTAB.
4410 (prinfport): don't use file_name in PTAB.
4411 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
4412 * ports.c (scm_add_to_port_table): don't intialize file_name.
4413 (scm_port_file_name): remove for now.
4414 * gc.c (scm_gc_mark): don't mark PTAB file_name.
4416 * fports.h (scm_mkfile): prototype deleted.
4417 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
4419 * debug.c, unif.c: use scm_out_of_range instead of
4420 wta for range errors (ASSERT still needs work).
4422 * error.c, error.h (scm_out_of_range): new procedure.
4424 * error.c, error.h (scm_out_of_range_key): new key.
4426 * posix.c (scm_sync): #else was missing.
4428 * error.c, error.h: append _key to names scm_num_overflow and
4431 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
4432 of consing an empty list.
4433 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
4434 of macros, saves code and string space.
4435 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
4436 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
4437 lower case. Rename scm_syserror_m to scm_syserror_msg.
4438 error.h: prototypes for new procedures.
4440 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
4442 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
4444 * error.c, error.h: setup scm_num_overflow key.
4446 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
4447 Remove definition of SCM_OVSCM_FLOW.
4449 * fports.c (scm_open_file): use SCM_SYSERROR_M.
4451 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
4452 explicit message and args.
4454 * error.c, error.h, __scm.h: change system_error_sym to
4457 * error.c (system_error_sym): remove leading %% from the Scheme name
4460 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
4462 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4464 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
4465 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
4466 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
4467 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
4468 renamed. (These were introduced by unsupervised name
4471 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4473 * print.c: Added code for detection of circular references during
4474 printing. (init_ref_stack, grow_ref_stack): New functions. Added
4475 a hook for printing of closures (accessible via print options).
4476 This leads to a split of calls to scm_iprin1 into two classes:
4477 elementary print operations (e. g. the code which prints a smob)
4478 still use scm_iprin1 while top level calls (like scm_display) use
4479 scm_prin1. scm_prin1 begins by clearing the data structure used
4480 to record reference information.
4482 * print.h: Added declarations of scm_prin1 and scm_prlist.
4484 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
4486 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
4488 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
4490 * error.c (err_head): scm_iprin1 --> scm_prin1
4492 * debug.c: Adjusted header comment.
4496 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4498 * strerror.c: Doc fix.
4500 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4502 * gdbint.c (gdb_read): Now possible to run during GC.
4503 (unmark_port, remark_port): New functions.
4505 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
4507 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
4508 of allocating a new string object. Also, increase size by
4509 the factor 2 instead of 1.5.
4511 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
4513 * __scm.h (SCM_P): Corrected to run under traditional C.
4515 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
4518 * async.c: Calls to scm_sysintern corrected.
4520 * async.h (scm_async_clock): Redundant declaration removed.
4522 * continuations.c (scm_dynthrow): Redundant declaration removed.
4524 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
4525 Definition typos corrected.
4527 * debug.h: Missing declarations of functions in debug.c added
4530 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
4531 Missing declarations to functions in eval.c added.
4533 * filesys.c: Possibly uninitialized variable rv.
4535 * gc.h (scm_object_addr, scm_unhash_name): Missing
4536 declarations of functions defined in gc.c added.
4538 * genio.c: Possible typos str_data -> wstr_data. ???
4540 * genio.c: Possibly unintended shadowing of local variable
4541 `int c' (gotos out of scope of inner `c'). ???
4543 * init.c: Uninitialized `SCM last' may be used.
4545 * ioext.h: (scm_sys_isatty_p): Typo.
4547 * list.h (scm_list_head): Missing prototype for function in
4550 * numbers.c (scm_two_doubles): Changed from extern to static
4551 (is used only within numbers.c).
4553 * numbers.h: Repeated declarations removed.
4555 * ports.h (scm_close_all_ports_except): Declaration for the
4556 function defined in ports.c added.
4558 * posix.h: Missing declarations added.
4560 * procs.h (scm_make_subr_opt): Missing declaration added.
4562 * socket.h (scm_sys_gethost): Missing declaration added.
4564 * socket.h: Redundant declarations removed (they are in fdsocket.h).
4566 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
4567 Missing declarations added.
4569 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
4571 * struct.c: Uninitialized variable `SCM answer' may be used.
4573 * unif.c (l2ra): Declaration prototype.
4575 * unif.c (scm_array_equal_p): Dummy definition removed (it is
4576 defined in ramap.c).
4578 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
4579 Redundant declarations removed (they are in ramap.h).
4581 * variable.h (scm_make_udvariable,
4582 scm_make_undefined_variable): Declaration corrected to
4583 correspond variable.c.
4585 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
4586 Missing declarations added.
4588 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
4590 * Makefile.in (distclean): Don't forget to delete fd.h.
4592 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4594 * fd.h.in, tags.h: Trivial cleanups.
4596 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
4597 marksweep.h just declared functions from gc.c.
4598 * gc.h, libguile.h: Don't #include "marksweep.h".
4599 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4600 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
4601 dependencies updated.
4603 * libguile.h: Don't #include "files.h"; it's been deleted.
4605 * files.c (scm_sys_delete_file): Moved to filesys.c.
4606 File is now empty; deleted.
4608 * filesys.c: scm_sys_delete_file is now here. Remove
4609 #if's; they seem to rely on remnants of an old portability
4610 regimen. If the problems come up again, solve them properly,
4611 using autoconf. Specifically: Don't test M_SYSV, and #define
4612 remove to be unlink if it's #defined; don't use remove just
4613 because HAVE_STDC_HEADERS is #defined.
4614 * filesys.h: Add declarations for scm_sys_delete_file.
4615 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4616 files.o, files.h, files.c, and files.x.
4617 * init.c: Don't #include "files.h", and don't call scm_init_files.
4619 Use SCM_P instead of PROTO; the latter intrudes on the user's
4621 * params.h: Deleted; definition of SCM_P moved to...
4622 * __scm.h: ... here, where it replaces PROTO macro.
4623 * libguile.h, smob.h: Don't #include "params.h".
4624 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
4625 smob.h: Fix prototypes accordingly.
4626 * Makefile.in: Update dependencies.
4627 (inner_h_files): Remove params.h.
4629 * gc.c: #include "gc.h"; every module should include its header,
4630 to let the compiler cross-check the declarations against the
4633 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
4634 simpos.h: #include "libguile/__scm.h".
4636 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
4638 * init.c: Don't forget to #include smob.h and init.h.
4639 * Makefile.in: Dependencies updated.
4641 * smob.h: Use PROTO instead of #if __STDC__.
4643 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
4645 * __scm.h: Doc fixes.
4647 * __scm.h, libguile.h: Use "quotes" in the #includes, not
4648 <angles>; this allows `make depends' to work properly.
4650 * libguile.h: #include smob.h and pairs.h before the others; they
4651 define typedefs used by other headers.
4653 C files should #include only the header files they need, not
4654 libguile.h (which #includes all the header files); the pointless
4655 recompilation was wasting my time.
4656 * Makefile.in (all .o dependency lists): Regenerated.
4657 * libguile.h: Don't try to get a definition for size_t here...
4658 * __scm.h: Do it here.
4659 * _scm.h: Since this is the internal libguile header, put things
4660 here that all (or a majority) of the libguile files will want.
4661 Don't #include <libguile.h> here; that generates dependencies on
4662 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
4663 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
4664 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

4761 * weaks.c: Get "weaks.h".
4763 * stackchk.h: #include "libguile/debug.h",
4765 * print.h, read.h: #include "options.h", since everyone who uses
4766 either of these files will need that.
4768 * smob.h: #include "ports.h", "genio.h", and "print.h", since
4769 anyone who uses this file will need them to define the smob
4770 printing functions. Also, get markers.h, since people will need
4771 to #define the mark functions.
4773 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
4774 * ports.h: ... to here.
4776 * ports.h (scm_port_table_size): Explicitly give type as 'int';
4777 don't rely on archaic C default type rules.
4779 * fports.h: #include "libguile/ports.h", since you need that in
4780 order to parse this.
4782 * genio.h: #include "libguile/print.h", because you need that to
4783 parse this; don't bother #including "ports.h", since print.h gets
4786 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
4788 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
4789 this; it's now a reference to an element of *scm_root.
4791 * debug.h: Don't #include "options.h"; the compiler won't be able
4792 to find that once the headers are installed; instead, #include
4793 "libguile/options.h".
4794 * gc.h: Same, with marksweep.h.
4795 * mbstrings.h: Same, with symbols.h.
4796 * scmhob.h: Same, with _scm.h.
4797 * smob.h: Same, with params.h.
4799 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
4800 C files; there's no need for this, and it forces recompilations
4803 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
4805 * error.c (scm_error): declare scm_error_callback.
4807 * error.h: prototype for scm_error_callback.
4809 * __scm.h: define lgh_error.
4810 (SCM_SYSERROR): redefine using lgh_error.
4812 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
4814 * error.c (scm_error): new procedure.
4816 * error.h: prototype for scm_error.
4818 * Makefile.in (install): install scmconfig.h from the current
4819 directory, not $(srcdir).
4821 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
4823 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
4824 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
4825 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
4826 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
4827 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
4828 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
4829 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
4830 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
4831 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
4832 vports.h, weaks.h: #include "libguile/__scm.h", not
4833 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
4834 dependencies are within libguile properly.
4836 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
4838 * Makefile.in (.c.x): Simplify; there's no need to run this rule
4839 when scmconfig.h doesn't exist.
4841 * load.c (scm_sys_try_load): Correct spelling.
4843 * feature.c (scm_loc_features): Make this static.
4845 * Makefile.in (libpath.h): Omit trailing slash from path. We
4846 shouldn't require it of users, so why put it here?
4848 Move code to initialize and search %load-path from ice-9 to C
4849 code, so we can use the load-path to find the ice-9 boot code;
4850 this makes it easier to run Guile without installing it. See
4851 corresponding changes in guile/Makefile.in.
4852 * feature.c: Move stuff concerned with the load path to load.c.
4853 (scm_compiled_library_path): Deleted.
4854 Don't #include libpath.h here.
4855 * feature.h: Don't mention scm_compiled_library_path.
4856 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
4857 <sys/stat.h>, and <unistd.h> (if present).
4858 (R_OK): #define if the system hasn't deigned to.
4859 (scm_loc_load_path): New variable.
4860 (scm_init_load_path, scm_sys_search_load_path,
4861 scm_sys_try_load_path): New functions.
4862 (scm_init_load): Initialize scm_loc_load_path to point to the
4863 value cell of the Scheme %load-path variable.
4864 * load.h: Add declarations for scm_sys_search_load_path,
4865 scm_sys_try_load_path.
4866 * init.c: Call scm_init_load_path.
4867 * Makefile.in (feature.o, load.o): Dependencies updated.
4869 * load.c, load.h: Rewrite using PROTO macro.
4871 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4873 * gc.c (scm_cellp): New function: C predicate to determine if an
4874 SCM value can be regarded as a pointer to a cell on the heap.
4876 * gc.h: Added declaration of scm_cellp.
4878 * gdb_interface.h: New file: The GDB interface header from the GDB
4881 * gdbint.c: New file: GDB interface.
4883 * gdbint.h: New file: GDB interface.
4885 * libguile.h: Added #include <libguile/gdbint.h>.
4887 * init.c (scm_boot_guile): Added scm_init_gdbint.
4889 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
4890 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
4891 found if object files and source are kept separate).
4893 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
4895 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
4897 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
4899 * configure.in: Don't substitute the values of TCL_SRC_DIR and
4900 TK_SRC_DIR; they're not relevant any more.
4902 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
4903 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
4905 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
4907 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
4908 search path, so we can find the <libguile/MUMBLE.h> headers.
4910 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
4912 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
4913 implicit in the .c.o rule.
4914 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
4917 Put the library path in a header file, instead of passing it on
4918 the command line in every compilation.
4919 * Makefile.in (libpath.h): New target.
4920 (feature.o): Depend on libpath.h.
4921 (clean): Delete libpath.h.
4922 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
4923 * feature.c: ... #include "libpath.h" here.
4924 * .cvsignore: Ignore libpath.h.
4926 Don't install the unwashed masses of Guile header files in the
4927 main #include path; put most of them in a subdirectory called
4928 'libguile'. This avoids naming conflicts between Guile header
4929 files and system header files (of which there were a few).
4930 * Makefile.in (pkgincludedir): Deleted.
4931 (innerincludedir): New variable; this and $(includedir) are enough.
4932 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
4933 (installed_h_files): Divide this up. Now this variable lists
4934 those header files which should go into $(includedir) (i.e. appear
4935 directly in the #include path), and ...
4936 (inner_h_files): ... this new variable says which files appear in
4937 a subdirectory, and are referred to as <libguile/mumble.h>.
4938 (h_files): List them both.
4939 (install): Create innerincludedir, not pkgincludedir. Put
4940 the installed_h_files and inner_h_files in their proper places.
4941 (uninstall): Corresponding changes.
4942 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
4943 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
4944 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
4945 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
4946 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
4947 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
4948 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
4949 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
4950 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
4951 vports.h, weaks.h: Find __scm.h in its new location.
4952 * __scm.h: Find scmconfig.h and tags.h in their new locations
4953 (they're both "inner" files).
4955 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
4957 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
4959 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4961 * posix.c: Doc fixes.
4963 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
4965 * socket.c: Don't include a prototype for inet_aton; just use a
4966 K&R style declaration, to avoid warnings but minimize the chance
4967 of conflicts with the system.
4969 On NextStep, <utime.h> doesn't define struct utime, unless we
4970 #define _POSIX_SOURCE before #including it.
4971 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
4972 * acconfig.h: New comment text for above CPP symbol.
4973 * configure.in: Call it.
4974 * posix.c: #define _POSIX_SOURCE if it seems necessary.
4976 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
4978 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
4979 testing for __EMX__.
4981 * posix.c: #include <libc.h>, if it exists.
4983 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
4984 don't even know if the latter exists.
4986 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
4987 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
4988 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
4990 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
4992 (scm_init_posix): Use them when initializing the Scheme constants
4995 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4997 * Makefile.in (libdir, includedir, bindir): Use the
4998 autoconf-supplied values, instead of deriving them ourselves.
4999 (pkgincludedir, datadir, pkgdatadir): New variables.
5000 (install, uninstall): Put the header files in a special
5001 subdirectory, not in the main search path.
5003 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5004 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5006 * Makefile.in (IMPLPATH): Deleted; never used.
5008 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5009 on the Tcl/Tk source any more.
5010 (INCLUDE_CFLAGS): Remove references to the above.
5012 * Makefile.in (version.o): Corrected dependencies.
5014 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5016 * libguile.h: #include "version.h"
5018 * init.c (scm_boot_guile): Call scm_init_version.
5019 * gscm.c (gscm_run_scm): Call scm_init_version.
5021 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5022 GUILE_VERSION): AC_DEFINE these.
5023 (acconfig.h): #undef the above symbols.
5025 * Makefile.in (libobjs): Add version.o.
5026 (installed_h_files): Add version.h.
5027 (c_files): Add version.c.
5028 (gen_c_files): Add version.x.
5029 (version.o): New rule.
5030 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5031 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
5032 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
5033 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
5034 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
5035 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
5036 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
5037 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
5038 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
5039 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5040 weaks.o): Add version.h to dependency lists.
5041 (markers.o): Remove duplicate rule.
5043 * version.h: New file.
5045 * version.c: New file.
5047 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5049 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5050 array; use it appropriately. Since GCC is quite happy to
5051 subscript functions, it never warned us about this; we should use
5052 -Wpointer-arith in the future. I guess we never tested
5055 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5057 * socket.c: Doc and copyright fixes.
5059 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5061 * debug.c: Fixed and improved gdb support.
5063 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5065 * socket.c: Added declaration of inet_aton to avoid compiler
5066 warning. (Hope this solution is correct.)
5068 * stime.c: Added declaration of ftime. (This is missing in
5071 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5073 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5075 * Makefile.in (c_files): add strerror.c.
5077 * strerror.c: new file from Emacs' sysdep.c.
5078 maybe configure should also check for sys_errlist.
5080 * configure.in (AC_REPLACE_FUNCS): add strerror.
5082 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5084 * debug.c (scm_init_debug): Added initialization for
5085 scm_evaluator_traps.
5087 * debug.h, debug.c: Various name changes.
5088 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5089 "debug-options-interface". See commentary in options.c.
5091 * options.h, options.c: Options now have documentation strings.
5092 Also added a long explanatory commentary.
5094 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5097 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5098 last_debug_info_frame is now updated in all cases.
5100 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5103 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5105 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5106 Added option STACK_CHECKING.
5108 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5110 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5112 * __scm.h: Removed symbols for debugging support.
5114 * acconfig.h: Added symbols for debugging support.
5116 * configure.in: Added user option for debugging support.
5117 --enable-debug will include the debugging code into libguile.a.
5119 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5120 scm_relocate_chunk_to_heap.
5122 * debug.c: New file: low-level debugging support. It also
5123 includes support for debugging with gdb. (The extensions to gdb
5124 are written by Per Bothner at Cygnus.)
5126 * debug.h: New file: low-level debugging support.
5128 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5129 argument pairs. Extensive modifications to the debugging
5130 evaluator. Added "SECTION:" commentaries to clarify what happens
5131 when, during double compilation. Renamed EVALIMP --> EVALIM.
5132 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5133 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5134 the beginning of the file. New procedure: scm_unmemocopy.
5135 Added some global state variables needed by the debugging
5136 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5137 check_entry, check_apply, check_exit, debug_options and
5138 evaluator_traps. New acro: undefine.
5140 * eval.h: Renamed EVAL --> XEVAL.
5142 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5143 --> scm_make_weak_key_hash_table.
5145 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5146 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5148 * libguile.h: Conditionally include debug.h
5150 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5151 scm_object_properties shouldn't return handle. `handle' now gets
5152 initialized in scm_set_object_properties_x. scm_object_properties
5153 doesn't any longer create an entry in scm_object_whash.
5155 * options.c: New file: handling of run time options.
5157 * options.h: New file: handling of run time options.
5159 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5161 * print.c: New procedure: scm_print_options
5163 * print.h: Defines for print options.
5165 * read.c: New procedure: scm_read_options
5167 * read.h: Defines for reader options.
5169 * root.h: Added scm_source_whash among scm_sys_protects.
5171 * srcprop.c: New file: source properties.
5173 * srcprop.h: New file: source properties.
5175 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5176 (Bug found by A. Green.)
5178 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5180 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5182 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5184 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5186 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5187 and should be called by the final client.
5189 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5191 * gc.h: Use the PROTO macro when declaring functions.
5192 * gc.c: Use the PROTO macro when declaring static functions.
5193 Remove the CPP hair around function definitions.
5195 * gc.c (scm_init_storage): Initialize scm_asyncs.
5197 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5198 preprocessor symbol; "__scm.h" is where it might get #defined.
5199 * __scm.h: Similar: #include <scmconfig.h> before testing
5202 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5204 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5206 * init.c (scm_boot_guile): Add init_func argument; call
5207 (*init_func) instead of calling scm_appinit; it's ucky to
5208 hard-code names for the user's procedures.
5209 * init.h (scm_boot_guile): Adjust declaration.
5211 * __scm.h (PROTO): New macro, for declaring functions with
5214 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5215 eliminate all the __STDC__ conditionals.
5216 (scm_boot_guile): Add declaration.
5217 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5218 Remove __STDC__ conditionals around function definitions; the
5219 declarations in init.h will provide the same information, more
5222 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5223 complain about it in the error message; the error message is
5224 adequate without that note, and there's nothing the user can do
5227 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5229 * Makefile.in (ancillary): Drop def.sed.
5231 * posix.c (scm_init_posix): Use numeric values, rather than
5232 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5233 F_OK. The symbols aren't available on some systems, and I'm
5234 pretty sure their values are fixed by common widespread practice.
5235 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5237 More functions unavailable on some systems.
5238 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5239 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5241 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5242 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5243 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5244 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5245 stub that signals an error as the #else.
5247 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
5249 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
5251 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
5253 * unif.c: include ramap.h.
5255 * read.c (endif): case_insensative_p renamed case_insensitive_p.
5257 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
5259 * ports.c: include sys/ioctl.h.
5261 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
5263 * configure.in: check for sys/ioctl.h.
5265 * ports.c: include <malloc.h> not "malloc.h".
5267 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5269 * fports.c: remove ttyname and tmpnam declarations.
5271 * posix.c: fewer ttyname declarations.
5273 * fports.c: include <string.h> not "string.h".
5275 * init.c, ioext.c: include string.h and unistd.h.
5277 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.

5299 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
5301 Changes for NeXT, suggested by Robert Brown.
5302 * configure.in: Call AC_TYPE_MODE_T.
5303 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
5304 NeXT. Put header file list in alphabetical order.
5305 * configure, scmconfig.h.in: Regenerated.
5306 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
5308 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
5311 * acconfig.h: New file, providing documentation for the CPP
5312 symbols defined in configure.in
5313 * acconfig-1.5.h: Removed; superceded by the above.
5315 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
5317 * ioext.c (scm_sys_fdopen): fix the port-table assignment.

5321 * ioext.c (fileno): renamed from %fileno.
5322 (soft-fileno): deleted.
5324 * ports.c (scm_port_revealed): don't need to check for -1 from
5326 (scm_set_port_revealed_x): return unspecified, not #f.
5328 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.

5334 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
5336 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5338 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5339 This is necessary on Ultrix, and doesn't hurt portability.
5341 * Makefile.in (dist-dir): New target, implementing a new dist system.
5342 (installed_h_files): Put in alphabetical order.
5343 Remove duplicate entries for markers.h and unif.h.

5345 (ancillary): Renamed from anillery; all uses changed. Remove
5346 PLUGIN; it's a directory, and needs special treatment in dist-dir.

5349 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5351 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5352 every if must have an else, or else the whole command has a
5353 non-zero exit code whenever the if's condition is false.
5355 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>

5420 matter so long as it is non-0 (got rid of "* 4").
5422 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
5424 * gscm.h: gscm_mkarray eliminated (presumably was not being used
5425 since its definition was bogus).
5427 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
5429 * mallocs.[ch]: back again (for rx at least).
5431 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
5433 * ports.c: removed functions relating to the mapping between ports
5434 and descriptors. (That stuff is unix-specific and should be collected
5435 in a separate library).

5442 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
5443 handled correctly (SCM_FREEP was applied to them) -- test for
5444 NIMP. Keys in weak hash tables were spuriously (though harmlessly)

5499 * ports.c (scm_add_to_port_table): Added fields
5500 to port table entries: file_name, line_num, col.

5612 initialization to fix a race condition.
5614 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

5638 set the multi_byte flag correctly in symbols. This is wrong.
5639 intern_obbary_soft and msymbolize should take an extra parameter.
5640 Also, weird multibyte symbols don't print correctly.
5641 The weird symbol syntax is also a bit bogus (emacs doesn't quite
