1 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3 * debug.h, debug.c (scm_start_stack): New function. Implements
4 the guts of old scm_m_start_stack.
6 * debug.c (scm_m_start_stack): Use scm_start_stack.
8 * init.c (scm_start_stack, scm_restart_stack): Renamed to
9 start_stack and restart_stack. (These have static scope.)
11 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
13 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
14 readline functions to come in release 2.3. (Thanks to Chet
16 (handle_errors): Use the above functions.
18 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
20 * readline.c: Improvements for readline support: Handle errors
21 better; Implement before-read-hook.
23 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
25 * init.c (scm_boot_guile_1), readline.c: Test for
26 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
27 assure that we have version >= 2.1.)
29 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
31 * readline.c (scm_add_history): Bugfix: Do strdup before giving
32 away the string to add_history.
33 (completion_function): Do completion for readline. (Thanks to
35 (scm_filename_completion_function): New procedure: Filename
37 (current_input_getc): New function. Use this one instead of
38 standard getc from readline.
40 * throw.c, throw.h (scm_handle_by_throw): New function: This
41 handler throws errors to next handler on the dynwind chain.
43 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
45 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
48 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
50 * procprop.c (scm_i_procedure_arity): New function. Returns arity
52 (scm_procedure_properties): Modified to return arity together with
54 (scm_procedure_property): Added the read-only property `arity'.
55 (scm_set_procedure_property_x): It is an error to set the `arity'
58 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
59 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
61 * procprop.h (scm_sym_arity): New symbol.
63 * objects.c (scm_set_object_procedure_x): New procedure: Use this
64 to set the dispatch procedure of an operator or entity object.
66 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
67 Made procedure slots read-only.
69 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
70 scm_tcs_cons_gloc case in zero args switch; Fixed args
71 construction for operators in scm_tcs_cons_gloc case in two args
74 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
76 * fluids.c: Removed use of assert.h (in order to avoid
79 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
81 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
83 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
84 change makes the evaluator safer at the cost of evaluation speed.
85 It handles the case when the user has added a non-immediate
86 improper end of the application form, e.g., `(+ 0 . x)'.
87 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
88 minimize the extra cost as much as possible. The new code is
89 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
90 problem with structs planted directly in the code (e.g. by a
91 macro). This no longer causes segmentation fault. (Thanks to
94 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
95 arg `proc' in order to be able to throw errors; New argument
98 * Removed extra #include "debug.h"
100 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
102 * scmsigs.c: Declare usleep as returning void on some systems.
103 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
106 * coop.c (usleep): Return void on some systems.
108 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
110 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
112 * coop.c: Changed return type of usleep to int.
114 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
115 isn't found in the OS.
117 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
118 isn't enabled. (Thought that I had made this change ages ago...)
120 * iselect.c: Declare bzero if not defined by OS.
122 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
124 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
125 condition. (Thanks to John Tobey.)
127 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
128 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
131 * __scm.h: Start the long-term project of moving to POSIX threads.
132 Phase 1: Classification of all critical sections.
133 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
134 for A sections. (See comments in __scm.h for details.)
136 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
137 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
139 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
141 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
142 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
143 (libpath.h, versiondat.h): Replaced dependency on Makefile with
144 dependencies on $(srcdir)/Makefile.in
145 $(top_builddir)/config.status in order to avoid circularity.
147 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
148 from argc if argc was 0 initially.
150 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
151 in generation of libpath.h.
153 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
155 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
156 libguile from 2 to 3.
158 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
160 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
162 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
164 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
165 scm_set_port_column_x, scm_port_filename,
166 scm_set_port_filename_x): Removed optional arguments. Added
167 proper argument checking.
169 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
170 stack size in machine words.
172 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
173 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
174 to Ole Myren Röhne.)
176 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
178 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
179 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
181 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
184 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
185 procedure apply: Copy argument lists before pushing them unto the
186 environment so that the environment won't get mutated due to
187 manipulation of procedure arguments. This should perhaps be
188 regarded as a temporary solution until someone finds a more
189 efficient one. (Thanks to Maciej Stachowiak.)
191 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
193 * script.c (scm_compile_shell_switches): Use "guile" as default
194 zero arg if argc is NULL.
196 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
198 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
199 is zero. (Thanks to Dirk Herrmann.)
201 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
203 * ports.c (scm_add_to_port_table): First line is now line 0
204 (was 1). (Interface changed according to suggestion by Per
207 * backtrace.c (display_header): Add 1 to line and column numbers
208 when presenting them to the user.
210 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
211 from debug.c --> eval.c
213 * eval.h, eval.c (scm_eval_options_interface): New options
215 (SCM_EVAL_STACK): New option: Size of newly created stacks,
216 i.e. stacks for new threads.
218 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
220 * eval.c (unsafe_setjmp): Removed with #if 0.
222 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
225 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
226 to avoid compiler warnings.
228 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
230 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
232 * throw.c (handler_message): Print message on current error port
233 instead of default error port. (Thanks to Maciej Stachowiak.)
235 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
237 * ports.c (scm_add_to_port_table): allocate in units of
238 struct scm_port_table *, not struct scm_port_table.
239 * posix.c (scm_close_pipe): remove the port from the port table
241 Thanks to Rob Engle for both fixes.
243 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
245 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
246 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
248 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
250 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
252 * backtrace.c (display_error_body, display_backtrace_body),
253 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
254 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
255 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
256 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
259 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
260 don't receive the jmpbuf arg anylonger.
261 (scm_catch): Don't accept a #f tag.
262 (scm_throw): Check that key is a symbol.
263 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
265 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
267 * async.c (async_pending): Removed declaration.
269 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
271 * dynwind.c (scm_wind_chain): New debug function.
273 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
274 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
275 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
276 extra layer of functions around the body and handler of a thread.
277 This extra layer makes sure that the handler is called in the
278 dynamic context of the surround (= empty dynwind list), but under
279 the *dynamic root* of the body. We can not use the dynamic root
280 of the surround since that root belongs to another thread => stack
281 is not handled correctly. It may seem ugly to use this extra
282 layer, but the extra cost in terms of execution time is really
283 negligible compared to the total amount of time required to create
284 a thread, and it would reduce maintainability to duplicate the
285 crucial and complicated steps performed by cwdr.
287 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
288 (SCM_ALLOW_INTS): Added thread switching code before interrupts
289 get re-enabled. The important effect of this is that interrupts
290 are blocked during thread switching so that thread data structures
291 don't risk getting messed up by an unfortunate signal.
292 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
293 seems to do more aggressive optimization which actually move
294 instructions around in these macros in a fatal way. Therefore:
295 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
296 just superstitious...)
297 (SCM_TICK): Maybe do a context switch and take care of asyncs.
298 This macro should be used instead of SCM_ASYNC_TICK since the
299 latter doesn't do context switches any more.
301 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
302 instead of SCM_ASYNC_TICK.
304 * coop.c, iselect.c: Since thread switches are now performed with
305 interrupts masked, we can't use the old mechanism of delivering
306 signals immediately when they arrive. Signals must instead be
307 delivered when the asyncs run *after* the end of the critical
308 section in scm_internal_select. But this also means after context
309 switch so that the signal will be delivered to a different thread.
310 To avoid this, I have changed the protocol of
311 coop_wait_for_runnable_thread and friends so that they are allowed
312 to return the original thread. So, if a signal arrives during
313 scm_internal_select, we won't any longer be forced do a context
314 switch, but can remain in the same thread and deliver the signal
317 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
318 scm_asyncs_pending and made it global.
320 * iselect.c: Small fixes.
322 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
323 coop_condition_variable_init, coop_condition_variable_wait,
324 coop_condition_variable_signal): Changed return type from `void'
325 to `int'. This is to adhere closer to the pthreads interface.
326 This, in turn, is part of an attempt to provide C versions of the
327 mutex and condition variable primitives which can be part of a
328 frontend to COOP or pthreads.
330 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
331 coop_condition_variable_destroy): New functions.
333 * coop-threads.c (scm_wait_condition_variable): Use
334 coop_condition_variable_wait_mutex.
336 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
337 Definitions moved to coop-defs.h.
339 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
340 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
341 scm_cond_destroy): New C interface to mutecis and cond vars.
343 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
345 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
347 * iselect.c: Now several threads can wait on the same file
348 descriptor. The behaviour is compatible with OS select: All
349 threads waiting for the fd return with the same status.
351 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
353 * coop-threads.c, threads.h (scm_spawn_thread): New function.
354 Can spawn a thread from application C code.
356 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
358 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
359 gh_doubles2scm): New functions.
361 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
363 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
364 commented-out version of gh_eval_str()
366 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
368 * socket.c (scm_bind): free soka after use.
370 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
372 * stime.c (tzvar): new variable.
373 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
374 avoid memory leaks when allocating.
376 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
378 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
381 * gc.c, tags.h: Doc fixes.
383 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
385 * eval.c (macro-eval!): Removed. This function was a design bug.
386 It allowed memoized code to leak out to the scheme level. Most
387 things that you could do with `macro-eval!' can be done with
390 1997-12-20 Tim Pierce <twp@skepsis.com>
392 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
393 scm_fgets now depends on ftell(3) to know how many bytes were
396 1997-12-15 Tim Pierce <twp@skepsis.com>
398 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
399 dealing with strings.
401 1997-12-13 Tim Pierce <twp@skepsis.com>
403 Make %read-line more suitable for implementing read-line efficiently.
404 * ioext.c (scm_read_line): Strip the terminating newline from a
405 string, and return a cons of the string and its terminator.
407 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
408 of the string that is read is stored in this memory location.
409 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
410 * genio.c, genio.h (scm_do_read_line): Update caller.
411 * ports.h (scm_ptobfuns): Update typedef.
412 * fports.c (scm_fptob, scm_pipob): Update struct.
414 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
416 * filesys.c (set_element): Return file descriptor.
417 (fill_select_type): Return the highest file descriptor.
418 (scm_select): Tell select about the highest file descriptor. On
419 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
420 Therefore the extra overhead for calculating the maximum fd seems
421 to be more than compensated. Is this correct? In any case,
422 scm_internal_select will be much faster with this info.
423 (scm_select, fill_select_type, set_element): Don't accept any kind
424 of object in the file descriptor list or vector.
426 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
428 * iselect.c (finalize_fd_sets): Bugfix.
430 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
432 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
433 when using scm_internal_select (since we might switch to another
436 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
438 * simpos.c (scm_system): always define: use sysmissing if not
439 available. Check for HAVE_SYSTEM instead of _Windows (does
440 Windows lack system or does it have an unusable one?).
441 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
442 Let the argument be optional: if not supplied, call system(NULL).
444 * ports.c (scm_close_port): relax the type check from OPPORTP to
445 PORTP; closing a closed port is allowed.
447 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
449 * fports.c (scm_fgets): Return if the last char in a chunk is
450 newline. When fgets returns a string whose length is `size-1', it
451 is ambiguous whether a whole line was retrieved, so we must check
452 explicitly whether a line terminator is present.
454 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
456 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
457 before taking the CDR. (Thanks to Harald Meland.)
459 * filesys.c (scm_stat): Slightly optimized.
461 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
463 * ports.c (scm_close_port): Make sure the port is open before
466 * guile-snarf.in: Pass args through to gcc in a way that preserves
467 whitespace boundaries. (Thanks to Greg Badros.)
469 1997-12-02 Tim Pierce <twp@skepsis.com>
471 * stacks.c (scm_frame_procedure): Reverse the logic in the return
472 statement. (Thanks to Doug Evans for pointing this out.)
474 1997-12-01 Tim Pierce <twp@skepsis.com>
476 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
478 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
480 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
481 errno macro expansion of this field name. (errno is a C
482 preprocessor macro on some systems.)
484 1997-11-29 Tim Pierce <twp@skepsis.com>
486 * iselect.c: Doc fix.
488 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
490 * init.c (scm_start_stack): Removed initialization of
491 scm_the_last_stack_var.
493 * backtrace.h: Declare scm_the_last_stack_var.
495 * backtrace.c: Define scm_the_last_stack_var.
497 * root.c (mark_root): Don't mark the_last_stack_var.
499 * root.h (scm_root_state): Removed the_last_stack_var.
501 * throw.c: Added #include "fluids.h"
502 (ss_handler): `the-last-stack' is now a fluid.
504 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
505 --> the_last_stack_fluid.
507 * backtrace.c: Added #include "fluids.h"
508 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
509 (scm_backtrace): `the-last-stack' is now a fluid.
511 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
512 after scm_init_fluids.
514 1997-11-28 Tim Pierce <twp@skepsis.com>
516 * iselect.c: #ifdef USE_THREADS around thread-related includes.
518 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
519 DLSYM_ADDS_USCORE to decide whether to add an underscore.
521 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
523 * iselect.c (coop_next_runnable_thread,
524 coop_wait_for_runnable_thread): Disable interrupts so that no
525 async is executed before a potential error_revive.
526 (scm_internal_select): Disable interrupts during the parts of the
527 code which manipulate the sleep queue and the file descriptors.
529 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
531 * Makefile.am: Added iselect.c and iselect.h.
533 * coop.c (coop_qinit): Initialize fields used by
535 (coop_qget, coop_qget, coop_tmp_queue): Made global.
536 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
537 replacement in iselect.c.
538 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
539 coop_join): If GUILE_ISELECT enabled, use
540 coop_wait_for_runnable_thread instead of
541 coop_next_runnable_thread.
542 (usleep, sleep): New replacements for system functions if
543 GUILE_ISELECT is enabled.
545 * coop-threads.h: Declare coop_wait_for_runnable_thread.
547 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
549 * filesys.c: Added #include "iselect.h". Moved FD-macros to
550 iselect.h. Implement Scheme level `select' using
551 scm_internal_select. (See NEWS.)
553 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
555 * init.c: Call scm_init_iselect.
557 * iselect.h, iselect.c: New files. Implements
558 scm_internal_select. (See NEWS.)
560 1997-11-27 Tim Pierce <twp@skepsis.com>
562 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
563 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
564 and scm_must_free, since ultimately the string returned will be copied
565 by scm_makfrom0str anyway. Also, read any characters that may have
566 been pushed onto the port with scm_ungetc.
567 * ports.c (scm_generic_fgets): Same as for scm_fgets.
568 * ioext.c (scm_read_line): Free string after Guilifying it.
569 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.

573 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
575 * gh.h: Safely wrap prototypes for c++ usage.
577 1997-11-25 Mark Galassi <rosalia@cygnus.com>
579 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
580 gh_repl (argc, argv).
582 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
584 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
585 and to invoke scm_shell().
586 (gh_launch_pad): took out the loading of boot-9.scm from here,
587 since it is probably best to let the user control that. In fact,
588 gh_repl() now invokes scm_shell() which does that.
590 1997-11-23 Mark Galassi <rosalia@cygnus.com>
592 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
595 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
597 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
598 yesterday's underscore patch. (Thanks to Marius Vollmer for

614 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
615 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
617 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
619 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
620 configure.in was changed).
622 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
624 * Makefile.am (modinclude_HEADERS): Include readline.h here.

627 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
629 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
630 OPORT is an `open' port, not an output port.
632 * filesys.c (scm_close, set_element, get_element, scm_chown,
633 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use

639 scm_close_all_ports_except, scm_set_current_output_port,
640 scm_set_current_error_port): Likewise
641 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
642 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
644 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
645 * backtrace.c (display_backtrace_body): Likewise
646 * fports (scm_setvbuf): Likewise
647 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,

650 * unif.c (scm_uniform_array_write): Likewise
652 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
654 Minor problems with substring-related tag changes.
655 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
656 exactly what we want to leave in to detect substrings.
657 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
658 * tags.h: Fix diagrams and comments describing the S tag bit;
659 remove vestigial remarks about the D tag bit.
660 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
661 * strings.c: Formatting tweaks.
663 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
664 variable first; then SCHEME_LOAD_PATH, with a warning message.
665 (scm_parse_path): New function.
666 * script.c: Doc fixes.
668 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
670 Readline support, from Daniel Risacher.

682 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
684 * gh_data.c (gh_vector_set_x): changed name to make it consistent
685 with the ! -> _x mapping when going from Scheme to C.
687 1997-10-19 Mark Galassi <rosalia@cygnus.com>
697 (gh_assoc): added these gh_ functions implemented as macros.
699 * gh_predicates.c (gh_null_p):
700 (gh_string_equal_p): added these two missing predicates.
702 * gh_list.c (gh_append):
707 (gh_set_cdr_x): added these routines as I go through and try to
708 complete the picture R4RS functions that should be mirrored in the
711 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
713 * tags.h (scm_tc7_substring): Changed the comment and code to
714 conform with the changes below. Folks! We have suddenly two new
715 free tc7 codes!!! Jummy, jummy!
717 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
719 * Makefile.in: Rebuilt.

746 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
748 Don't include "mbstrings.h".
749 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
750 (SCM_SYMBOL_SLOTS): Define as 4.
751 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.

766 (scm_gen_putc, scm_gen_puts, scm_gen_write, scm_get_getc):
768 (scm_putc, scm_puts, scm_lfwrite): No longer static.
769 (scm_getc): No longer static; handle line and column changes.
770 (scm_ungetc): Renamed from scm_gen_ungetc.
771 (scm_do_read_line): Renamed from scm_gen_read_line.
772 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"

775 1997-10-12 Mark Galassi <rosalia@cygnus.com>
777 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
779 * gh_test_c.c (c_vector_test): some improvements on the vector
782 * gh.h (gh_vector): this used to exist but do the wrong thing.
783 Now it (almost) does the right thing, though it takes a list
784 instead of the individual arguments. I need to see how it could
786 (gh_list_to_vector): added this function as a macro. Corresponds
787 to Scheme's (list->vector ...).
788 (gh_vector_to_list): added this function as a macro. Corresponds
789 to Scheme's (vector->list ...).
791 * gh_data.c (gh_vector_ref): renamed from gh_vref to
792 gh_vector_ref, so that it resembles the Scheme routines more.
793 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
794 resembles the Scheme routines more.
795 (gh_make_vector): this used to be (stupidly) called gh_vector().
796 This is the right name, since it does the same thing as the Scheme
797 (make-vector ...) procedure.
799 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
801 * ports.h: #include "libguile/print.h"
803 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
804 Some indentation fixes.
806 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
807 longer a user field; New field: class_flags.
809 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
811 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
813 * gh_data.c (gh_bool2scm): new function which replaces
814 gh_int2scmb(), which is now tagged as obsolete.
816 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
818 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
819 macros should by convention not test for NIMPness.)
820 (SCM_COERCE_OPORT): Adjust indentation.
822 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
823 SCM_NIMP test before SCM_PRINT_STATE_P.
825 * struct.c, struct.h, gc.c: Renamed:
826 scm_struct_i_layout --> scm_vtable_index_layout
827 scm_struct_i_vcell --> scm_vtable_index_vcell

830 scm_struct_i_vtable_offset --> scm_vtable_offset_user
832 * struct.c (scm_print_struct): Use new printer slot; Default
833 printing: Also output hex code of vtable so that type identity
834 will be indicated as well.
835 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
836 Removed struct_printer_var; Removed struct-vtable-offset;
837 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
838 vtable-offset-user): New constants.
840 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
841 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
842 If this slot contains a procedure, use that to print structures of
843 the type represented by this vtable.
845 * print.c (scm_iprin1): Don't print arguments of macro
846 transformers. (They are always: exp env.); Bugfix: Unmemoize
847 transformer source with correct environment.
849 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
851 Streamlining of call-with-dynamic-root:
853 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
854 there is now only one catch.
855 (cwdr_outer_body): Removed.
856 (cwdr_handler): New function.
857 (scm_internal_cwdr): New function to perform the function of cwdr
858 but take args that are more useful to C code. Also, the handler
859 is now invoked *outside* of the new dynamic root, like the docs
860 say. We no longer have to catch absolutely all errors, the caller
861 is responsible for using a handler that does not throw, if he
863 (cwdr): Reimplemented in terms of scm_internal_cwdr.
864 * root.h (scm_internal_cwdr): New prototype.
866 Even more but risky streamlining:
868 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
869 allocation of the jumpbuf of a root continuation. The changes
870 below are controlled by it. They are now deactivated.
871 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
872 the JMPBUF of the scm_rootcont to NULL before returning.
874 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
875 when they are non-NULL.
876 (scm_gc_mark): Likewise, mark only when non-NULL.
878 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
879 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
881 * gc.c (scm_done_malloc): New function.
882 gc.h (scm_done_malloc): New prototype.
884 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
885 (struct scm_print_state) [revealed]: New field.

891 a certain value is acceptable as a port argument.
892 (scm_print_state_vtable): New variable.
893 (scm_free_print_state): Set `revealed' field to false.
894 (scm_iprin1): Call user supplied closure printer with
895 scm_printer_apply. Print in the traditional way when there isn't
896 one or when it returns #f.
897 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
898 Accept a port/print-state pair in addition to just a port.
899 (scm_prin1): Don't return the print_state to the pool when it has
901 (scm_printer_apply): Set `revealed' field of print_state to true.
902 (scm_init_print): Set scm_print_state_vtable.
903 (print_state_fluid, print_state_fluid_num): Removed.
905 * throw.h (scm_handle_by_proc_catching_all): New prototype
906 throw.c (scm_handle_by_proc_catching_all): New function
908 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
910 * Makefile.in: Regenerated with automake 1.2c.
912 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
914 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
915 was looping endlessly.
917 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
919 * strports.c (scm_eval_string): Don't close the port.
921 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
922 former returns a nice normal integer. (Thanks to Daniel
925 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
927 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
928 makefile variable as a build parameter called LIBS. The
929 build-guile program will use this, for the time being.
930 * Makefile.in: Regenerated.
932 Thanks to Shiro Kawai:
933 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
934 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
937 * Makefile.in: Regenerated with automake 1.2a.
939 * script.c (scm_compile_shell_switches): If we hit the -c or --
940 arguments, don't set the car of (command-line) to scm_usage_name,
941 the prettified name of the guile executable; give it the full
942 path, the way shells usually handle $0.
944 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
946 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
947 Scheme-level name `array-map' and renamed `serial-array-map' to
950 * backtrace.c: Introduced exception handlers which now enclose
951 `display-error' and `display-backtrace' so that error reporting
952 won't get into infinite loops if an error occurs during displaying
953 of the error. This can very easily happen with user supplied
954 print call-back routines.
956 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
958 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
959 the names `serial-array-map' and `array-map' should be removed.)
961 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
963 * init.c (scm_boot_guile_1): Added scm_init_objects ().
964 Added #include "objects.h"
966 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
967 Add #include "feature.h".
969 * Makefile.am (libguile_la_SOURCES): Added objects.c.
970 (modinclude_HEADERS): Added objects.h.
972 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
973 This test is needed at many places in the code and should be
974 abstracted. (Motivated by the need of this test in libguiletk.)
976 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
977 (scm_eval_string), load.c (scm_primitive_load,
978 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
979 Use SCM_EOF_OBJECT_P.
981 * eval.c (scm_init_eval): Add feature `delay'.
983 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
987 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
989 * list.h (SCM_LISTn): New macros. Make list creation in C code
990 prettier. The idea comes from STk.
992 * sequences.h, sequences.c, append.h, append.c: Removed. These
993 files implemented non-R4RS operations which would encourage
994 non-portable programming style and less easy-to-read code.
996 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
999 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1000 sequences.h, #include append.h.
1002 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1005 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1007 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1009 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1011 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1013 * eval.c: Added #include "objects.h"
1015 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1018 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1019 adjacent smob numbers.
1021 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1023 * procprop.h: Added declaration of scm_i_inner_name.
1025 * gsubr.c: New global symbol scm_i_inner_name.
1027 * debug.c (scm_procedure_name): Try procedure property
1028 `inner-name' if `name' fails.
1030 * print.c (scm_iprin1): Use scm_macro_name.
1032 * eval.c (scm_m_define): Give names to macros as well; Only the
1033 first top-level definition gives a procedure/macro a name.
1034 Otherwise confusing names can turn up in backtraces.
1035 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1036 `name'; Give names to macros as well.
1038 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1039 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1042 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1044 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
1046 (prinmacro): Removed. The code has been moved/merged into print.c
1047 in order to decrease code redundancy. We want macros to print in
1048 a way equivalent to procedures, and it would be silly to duplicate
1049 the required code. (We don't want to maintain two places.)
1050 (macrosmob): Print field is now a NULL pointer.
1052 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1053 scm_macro_transformer): New prototypes.
1054 (scm_tc16_macro): Declared.
1056 * * print.c (scm_iprin1): Added code for printing of macros. Macros
1057 are now printed in a way equivalent to procedures.
1059 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1061 * procs.h (scm_closure_p): Added declaration.
1063 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1065 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
1066 Shouldn't pass "heap" as the subr name.
1068 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1070 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
1071 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
1072 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1073 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1074 SCM_BOOL_T. Any non-false value is true.
1076 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1078 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1079 scm_gensym): Added prototypes.
1081 * symbols.c (scm_gensym): New function. This will speed up
1082 certain types of applications (such as macro systems) which
1083 generate lots of symbols.
1085 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1087 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
1089 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
1091 * unif.c (scm_shap2ra): tighten the checking of the array dimension
1092 specifier, since (2) or (2 . 3) would cause SEGV.
1093 (scm_transpose_array): more argument checking fixes.
1095 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1097 * Makefile.in: Regenerated.
1099 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1101 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
1103 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1105 * error.c, error.h (scm_error_callback): Removed (see NEWS).
1107 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
1109 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
1110 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
1113 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
1114 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1115 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
1116 scm_array_p, scm_array_rank, scm_array_dimensions,
1117 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
1118 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
1119 scm_array_prototype): Added case scm_tc7_wvect.
1121 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
1123 * errno.h: prototype for scm_strerror.
1124 * error.c (scm_strerror): new procedure.
1126 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1128 * list.c (scm_list_append_x): Allow non-pair as last argument.
1129 This is consistent with the R4RS append and is probably the
1130 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1132 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1134 * stime.h: prototype for scm_times.
1135 * stime.c (scm_times): new procedure.
1136 * ioext.c (scm_fseek): if the first argument is a file descriptor
1138 (scm_ftell): if the first argument is a file descriptor call lseek
1140 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
1141 * filesys.c (scm_chmod): if the first argument is a file descriptor,
1143 (scm_chown): if the first argument is a port or file descriptor,
1145 (scm_truncate_file): new procedure.

1152 third argument is now optional.
1154 * posix.c (scm_execl, scm_execlp): make the filename argument
1155 compulsory, since omitting it causes SEGV.
1156 (scm_sync): return unspecified instead of #f.
1157 (scm_execle): new procedure.
1158 (environ_list_to_c): new procedure.
1159 (scm_environ): use environ_list_to_c. disable interrupts.
1160 (scm_convert_exec_args): take pos and subr arguments and
1161 improve error checking.
1163 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1165 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1166 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1167 argument to SCM_ASSERT. Furthermore, the name of the function
1168 should be passed as first argument when signalling
1169 SCM_WNA. (Thanks to Thomas Morgan)
1171 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1172 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1173 dispatches on the number of actual args has a default case
1174 reporting an internal error. This is a vestige from a version
1175 that mallocated a SCM vector to hold the arguments. In the
1176 current version this check is too late: if it ever happens we will
1177 have already overstepped the bounds of the array.
1179 Also, the patch [...] adds a check for too many actual arguments."
1181 mdj: Removed check for "internal programming error".
1183 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1185 * gh_io.c (gh_write): New function.
1187 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
1188 throw.c (scm_internal_stack_catch): New sibling to the other catch
1189 functions. Code moved from gh_eval.c.
1190 throw.h: Added header.
1191 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
1192 scm_internal_stack_catch.

1196 * ioext.h: fix up prototypes.
1197 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
1198 Scheme name is now dup->fdes.
1199 (scm_dup_to_fdes): make the second argument optional and
1200 fold in the functionality of scm_primitive_dup.
1201 (scm_primitive_dup): deleted.
1203 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1205 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
1206 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
1207 ultrix are defined. Use setvbuf instead of setbuf.
1208 (scm_setvbuf): new procedure.
1209 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
1210 (scm_setfileno): moved from ioext.c.

1222 state as nested data while they are printed.
1223 (print_state_fluid, print_state_fluid_num): New variables.
1224 (scm_init_print): Initialize them.
1225 (scm_iprin): If print_state_fluid carries a print_state, use that
1226 instead of creating a new one.
1227 (scm_printer_apply, apply_stub, struct apply_data): New
1228 definitions to help with calling printer functions written in
1230 * print.h (scm_printer_apply): New prototype.

1243 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
1244 SCM_ASSERT: arg comes before pos.
1246 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1248 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
1249 to a list of length zero correctly.
1251 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

1267 * ioext.h: removed scm_duplicate_port prototype.
1269 * ioext.c (scm_primitive_dup2): return the new file descriptor
1270 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
1272 (scm_fdopen): bug fix: don't try to make port unbuffered until its
1273 stream has been set.
1274 (scm_duplicate_port): deleted, there's now an implementation in
1276 (scm_primitive_dup2): do nothing if newfd == oldfd.
1278 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>

1289 * ports.h: prototypes too.
1290 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
1292 * fports.h: prototype too.
1293 * fports.c (scm_evict_ports): moved from ioext.c.
1295 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>

1300 * filesys.h: scm_close prototype.
1301 * filesys.c (scm_close): new procedure, can close file descriptors
1302 and ports (scsh compatible).
1304 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an

1326 * dynl.c (free_dynl_obj): New function to free the dynamic object
1327 data. (dynl_smob): Use it.
1328 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
1329 the dynamic object data below the linking of the object to avoid
1330 memory leak when the linking code throws an error. Now the code
1331 leaks a whole dynamically linked library when must_malloc throws,
1332 but that should be much less likely.
1334 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
1336 Changes to compile under gnu-win32, from Marcus Daniels:

1374 think this is left over from the (eq? '() #f) days.
1376 * read.c (recsexpr): Give this a dummy definition if
1377 DEBUG_EXTENSIONS isn't #defined.
1379 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
1381 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

1392 alloca.lo will be included in @LIBLOBJS@. Something better than
1393 this should be possible.
1394 * Makefile.in: Regenerated.
1396 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>

1406 have to do this explicitly. Also, if regexp/basic is supplied, then
1407 turn off REG_EXTENDED.
1408 (scm_init_regex_posix): New regexp/basic symbol.
1409 (REG_BASIC): #define this if it is not already present.

1432 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
1434 (scm_init_regex_posix): Define constants for the REG_mumble flags;

1456 (cwdr_outer_body): New function, to establish the user's handler,
1457 and pass control to cwdr_inner_body.

1468 across this. Only works on GCC. Otherwise, we hope for the best.
1469 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
1470 the feeling that real thread systems will not need this...
1472 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
1474 Try to detect when people are using one version of libguile and a

1486 primitive definitions under their Scheme names.
1488 * Makefile.am (libguile_la_LDFLAGS): Update library version to
1489 1:2. Helps avoid confusion between installed and uninstalled libs.
1491 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
1494 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
1495 backslash from definition; this should be used like: GDB_INTERFACE;

1499 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
1500 new port unbuffered until its stream has been set.
1502 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
1504 * ports.h: new prototype.
1505 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
1507 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
1509 Make things compile neatly under Sun's C compiler.
1510 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
1511 * extchrs.c (xmbtowc): Make the second arg a normal char, not
1512 unsigned, because that's what the ANSI function takes.
1513 * extchrs.h (xmbtowc): Corresponding change to prototype.
1514 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
1516 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
1517 argument plain char *.
1518 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
1520 * tag.c (scm_tag): Remove unreachable statement.
1521 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
1522 top of the word, it should be unsigned.
1524 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
1525 is defined, to avoid warnings; it's only used in the
1526 conflict-checking code. Which might go away anyway.
1527 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
1528 conditionals; put the label definition in an #if too, to stifle
1531 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
1532 ChangeLog-threads in the distribution.
1533 * Makefile.in: Regenerated.
1535 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1537 * guile-snarf.in: Changed regexp to support CPPs that insert
1538 whitespace between lexical tokens (which munges the `%%%' snarf
1541 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1543 * load.c (scm_init_load_path): Append $(datadir)/guile to
1544 %load-path, so modules do not have to be installed in Guile's
1545 current version directory.
1547 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
1549 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
1550 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
1551 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
1552 call the sysdep functions with deferred ints.
1553 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
1554 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
1555 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
1558 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
1561 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
1563 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
1565 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
1567 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
1570 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
1572 * eval.c (scm_lookupcar1): New procedure to cope with a race
1573 condition during lookup (when using threads).
1574 (scm_lookupcar): Implement in terms of scm_lookupcar1.
1575 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
1578 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
1580 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
1581 supplied. (Change from Tim Pierce.)
1583 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
1585 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
1586 23:47:01 1997" changelog: Slots are now initialized with `#f' by
1587 default and not `()'. `#f' is the canonical non-value in Scheme,
1590 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1592 * struct.c (struct_printer): New variable that holds a handle on
1593 the Scheme variable *struct-printer*. This variable can be set by
1594 Scheme code to override the printing of structures.
1595 (scm_print_struct): If struct_printer is set, call it. If it is
1596 not set, or returns #f, print the structure in the old fashion.
1597 Include "eval.h" for scm_apply.
1599 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
1601 * struct.c (scm_struct_ref, scm_struct_set_x): Use
1602 scm_struct_i_n_words to get the number of fields, not
1603 -scm_struct_n_extra_words.
1605 On the route to fancier struct printing:
1606 * struct.c (scm_print_struct): New function to print a structure.
1607 Include "genio.h" to support it. This function doesn't do
1608 anything interesting right now, but I think it should be here
1610 * struct.h: Include "print.h" and add prototype for
1612 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
1613 print structures ourself.
1615 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
1617 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
1618 before applying the handler in case it doesn't return.
1620 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
1622 * scmsigs.h, async.h: updated.
1624 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
1627 * posix.c (scm_uname): interpret only negative values as an error.
1628 Solaris normally returns a positive value.
1630 * script.c (scm_compile_shell_switches): if we are not going into
1631 an interactive repl, set scm_mask_ints to zero so that asyncs can
1634 * simpos.c (scm_system): don't ignore/unignore signals around
1637 * posix.c (scm_open_pipe): don't ignore/unignore signals around
1640 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
1641 done in boot-9.scm instead.
1643 * scmsigs.c, async.c: Major rewriting of signal handling code.
1644 (scm_sigaction): new procedure.
1645 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
1647 (scm_raise): return unspecified, throw error on failure.
1649 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
1651 * regex-posix.c (scm_init_regex_posix): Register the "regex"
1652 feature, to help boot-9.scm decide whether to import the regex
1655 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
1657 * eval.c: Include scmconfig.h at the beginning of the file so that
1658 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
1661 * regex-posix.c: #include "_scm.h" before conditionally #including
1662 <regex.h>; the former defines HAVE_REGCOMP.
1664 * regex-posix.c: #include <regex.h> conditionally, so the file is
1665 CPP'able (for dependency scanning) even on systems that don't have
1668 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
1670 Add new R4RS-compliant syntax for keywords.
1671 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
1672 regardless of the setting of the `keywords' read option.
1673 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
1674 can be re-read no matter what the setting of the `keywords' read
1677 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
1679 Add support for POSIX regular expressions.
1681 * regex-posix.c, regex-posix.h: New files. (Some code
1682 is taken liberally from rx/rgx.c in the old Guile dist.)
1684 * init.c: Include regex-posix.h.
1685 (scm_boot_guile_1): Call scm_init_regex_posix.
1687 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
1688 Add regex-posix.[ch] sources.
1689 * Makefile.in: Regenerated.
1691 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
1692 to do this automatically? It didn't for me, bleh.)
1694 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
1696 * fports.c (print_pipe_port): New function.
1697 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
1698 latter doesn't even take the right arguments.
1700 * Makefile.am: Increment shared lib revision number. I think
1701 sometimes the uninstalled Guile finds the installed shared lib;
1702 Gord says doing this might help. As things turned out, I can't
1703 say whether it does.
1704 * Makefile.in: Regenerated.
1706 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
1707 passing it as the closure argument to scm_boot_guile. (Bill
1710 * ports.c (print_void_port, putc_void_port, puts_void_port,
1711 write_void_port, flush_void_port, getc_void_port, close_void_port,
1712 noop0): Use ANSI prototypes instead of K&R declarations, so the
1713 initialization of void_port_ptob gets aggressively type-checked.
1714 Fix arguments of print_void_port and write_void_port. (Bill

1748 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
1750 * script.c (scm_find_executable): Use prototype-style definition
1751 here; apparently it's not quite right to have const in a prototype
1752 and then use a K&R declaration. I wonder if stuff like this will
1753 go away if we compile with -Wrequire-prototypes, or whatever that
1754 is... (Bernard URBAN)
1756 * scmhob.h: New text from Bernard URBAN.
1758 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
1760 * script.c: Don't #define const on hpux. Configure takes care of
1761 this. (Thanks to Larry Schwimmer.)
1763 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
1764 decide whether to #include <unistd.h>, instead of listing a bunch
1765 of systems. Don't #include stdio twice. Removed dyked-out
1766 definition of scm_find_impl_file.
1768 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
1770 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
1771 library version info to 1:0.

1778 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
1779 throw.c: Update copyright years; these files have been worked on
1780 significantly in 1997, but only had copyright years for 1996.
1781 Also, change name of copyright holder on some from Mikael
1782 Djurfeldt to Free Software Foundation; he has signed papers
1783 assigning the changes to the FSF.
1785 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
1786 reason not to give the user the option.
1788 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
1789 Return #f on end-of-file when scanning table (i.e. when called
1790 with no arguments). Try to catch errors, when we can.
1791 * posix.c (scm_getgrgid, scm_getpwuid): Same.
1793 * script.h (scm_shell_usage, scm_compile_shell_switches): New
1794 external declarations. These are useful.
1796 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
1798 * posix.c: don't include <sys/select.h> or define macros for
1799 select, since they were not used in this file.
1801 * filesys.c (scm_select): make the fifth parameter microseconds,
1802 not milliseconds. let the fourth parameter be either a real value
1803 or an integer or #f. The first, second and third arguments can
1804 now be vectors: the type of the corresponding return set will be
1806 (set_element, get_element): new static procedures.
1808 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
1810 * strports.c (scm_eval_string): New function.
1811 (scm_eval_0str): Trivially re-implemented in terms of
1813 * strports.h (scm_eval_string): New extern decl.
1815 * net_db.c (h_errno): Add extern decl for this.
1817 * fports.c (local_pclose): New function.
1818 (scm_pipob): Use it in the initializer here.
1821 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
1822 Use a meaningful error message when signalling an error. For
1823 this, scm_gethost must check h_errno rather than errno.
1825 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
1827 * Makefile.in: Regenerated, using automake-1.1p.
1829 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
1831 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
1832 not SCM_UNSPECIFIED.
1834 * script.c (scm_compile_shell_switches): don't append (quit) if
1836 (scm_shell): call scm_exit_status and exit on the result of the
1839 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
1841 Ensure that shared substrings are handled properly when passed to
1842 a system call or other foreign function. Many thanks to Tim
1844 * symbols.h (SCM_COERCE_SUBSTR): new macro.
1845 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
1846 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
1847 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

1859 SCM_COERCE_SUBSTR to make sure shared substrings are
1862 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
1864 * error.c (scm_error): Add newline to error message.
1866 * init.c (scm_init_standard_ports): Doc fix.
1868 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1870 * dynl-shl.c: Completely replaced with new code from Bernard
1873 * script.c (scm_ice_9_already_loaded): New variable.
1874 (scm_compile_shell_switches): Use it.
1876 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1878 * filesys.c (scm_input_waiting_p): add missing third argument to
1881 * stime.c (scm_localtime): copy the result of localtime before
1882 calling gmtime in case they share a buffer.
1883 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
1886 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
1888 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
1890 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
1892 * Makefile.am (check-local): New target, which causes 'make check'
1893 to run gh_test_c and gh_test_repl, with some trivial input.
1894 * Makefile.in: Rgnrtd.
1896 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
1898 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
1901 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
1903 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
1904 sure how this was supposed to work.
1905 (scm_async_click): don't send SCM_TICK_SIGNAL.
1906 (scm_init_async): don't initialize %tick-thunk.
1908 * the following change doesn't affect the Scheme interface:
1909 gc-thunk is called at the end of garbage collection. however it's
1910 no longer implemented by pretending it's a signal.
1912 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
1913 system async corresponding to scm_gc_thunk.
1914 * async.h: declare scm_gc_async.
1915 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
1916 gc-thunk directly, instead of going through a signal handler.
1917 (scm_gc_async): new variable, points to the GC system-async.
1918 (scm_init_async): save the GC async as scm_gc_async instead
1919 of using system_signal_asyncs.
1920 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
1922 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>

1925 Don't screw up if we're interrupted.
1926 * Makefile.in: Regeneradet.
1928 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
1930 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
1932 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
1933 we're not using AM_INIT_GUILE_MODULE any more.
1934 * Makefile.in: Reneregated.
1936 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>

1946 Changes for reduced Guile distribution: one configure script,
1948 * configure.in, configure: Removed.
1949 * acconfig.h, acinclude.m4: Moved to parent directory, where the
1950 real configure script lives.
1951 * Makefile.in, scmconfig.h.in: Regenerated.

1958 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
1959 scm_must_malloc, not raw malloc.
1961 * script.c (scm_compile_shell_switches): Dyke out debugging output
1964 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1966 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
1968 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
1969 system has them. Hope this is safe. Previously
1970 sys/timeb.h was included if HAVE_FTIME was defined or if
1971 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
1972 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
1974 * ioext.c (scm_setfileno): add missing third argument to
1975 scm_misc_error call.
1977 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
1979 * eq.c (scm_equal_p): Correctly compare strings of different
1980 varieties. (Thanks to Tim Pierce.)
1982 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
1984 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
1985 #! block comment must occur on a line all by itself.
1987 Move most of the guts of shell command processing into libguile,
1988 so guile.c can be very small (and eventuallly auto-generated. (I
1989 mean, generated mechanically, not self-generated. Hmm.))
1990 * guile.c, script.c, script.h: New source files.
1991 * init.c (scm_boot_guile_1): Call scm_init_script.
1992 * libguile.h: #include "script.h".
1993 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
1994 targets, for new executable.
1995 (libguile_la_SOURCES): Mention script.c.
1996 (modinclude_HEADERS): Add script.h.
1997 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
1998 not dynamic linking is enabled. This is because we're generating
1999 executables now. Move CY_AC_WITH_THREADS call after those, so the
2000 values of cy_cv_threads_libs captures the libs chosen above.
2001 * Makefile.in, configure, aclocal.m4: Regenerated.
2003 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2004 We don't maintain this interface any more, and it just confuses
2007 * alloca.c: #include <scmconfig.h>, not <config.h>.
2008 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2009 it'll get included in disties.
2011 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2013 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2014 be distributed, because they confuse people.
2015 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2017 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2019 * configure.in: check for presence of gethostent (not present on
2020 OpenBSD by default).
2021 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2022 * configure, scmconfig.h.in: Regenerated.
2024 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2026 * backtrace.c (scm_backtrace): Split message string across
2027 newlines properly. GCC is more tolerant of this than other

2038 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2039 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2040 coop-threads.c.cygnus, coop-threads.h.cygnus.
2041 * configure.in: If we're using threads, include threads.o in
2043 * _scm.h, libguile.h: threads.h lives in this directory now.
2044 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2045 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2046 currently used, but brought along for information's sake.
2047 * ChangeLog-threads: log from old 'threads' directory.
2048 * Makefile.in, configure: Rebuilt.
2050 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2052 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2055 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2057 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2059 Merge GH interface library into libguile.
2060 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
2061 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2062 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2063 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2065 (EXTRA_libguile_la_SOURCES): ... here.
2066 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2067 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2068 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2069 New variables, describing how to build the gh test programs.
2070 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2071 build the test programs, and we probably should have been linking
2072 libguile.la against them all along, to support AIX shared libs.
2073 Add cflags for threads to CFLAGS; add libs for threads to new
2074 variable THREAD_LIBS, used in Makefile.am.
2075 * ChangeLog-gh: log from old `gh' subdirectory.
2076 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2078 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2080 * acconfig.h: Undo change of Apr 9; including the definition of
2081 PACKAGE in the guile headers conflicts with applications' own

2094 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2096 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2097 have S_IFSOCK. This is the case under Ultrix.
2099 * posix.c (scm_status_exit_val, scm_status_exit_val,
2100 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2101 Ultrix versions of WIFSTOPPED, etc., which assume that their
2102 arguments are lvalues (hmm).
2104 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2106 * eval.c: Doc fixes.
2108 * throw.c: Doc fixes; rearranged.
2110 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.

2114 * acconfig.h: Added entry for PACKAGE.
2115 * scmconfig.h.in: Regenerated.

2118 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2119 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
2121 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
2123 * Makefile.in: Rebuild.
2125 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2127 * stime.c (scm_mktime): take an optional zone argument.
2128 (scm_localtime): check putenv return value.
2129 (scm_strftime, scm_strptime): moved from posix.c. move #include
2131 stime.h, posix.h: update prototypes.
2132 (bdtime2c, setzone, restorezone): new static procedures.
2133 (scm_mktime, scm_strftime): use them.
2134 (scm_strftime): don't call mktime before strftime. Use
2135 filltime for return value.
2136 (filltime): convert NULL zname to #f.
2137 (scm_strptime): return a count of characters consumed, not
2138 the remaining string.

2145 Uncomment localtime and mktime.
2147 * configure.in: add AC_STRUCT_TIMEZONE.

2151 * stime.c (scm_init_stime): don't define ticks/sec.
2152 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2153 return value problem and is still portable.)
2155 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2157 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2158 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2159 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2160 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2161 cpp_err_symbols.c): Corresponding changes.
2162 * Makefile.in: Regenerated.
2164 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2166 * posix.c (scm_putenv): don't check HAVE_PUTENV.
2167 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
2168 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
2169 * putenv.c: new file, from sh-utils 1.12.
2171 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2172 since allocation isn't for Scheme objects.
2173 (scm_putenv): copy strings before placing in the environment.
2175 * stime.c (scm_current_time): throw an error if time returns -1,
2176 instead of returning #f.
2177 (scm_get_internal_real_time, scm_get_internal_real_time): use
2178 scm_long2num for return value instead of SCM_MAKINUM.
2180 * stime.h: prototypes updated.
2182 * stime.c (scm_time_in_msec): apparently unused, deleted.
2184 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2186 * configure.in: check for gettimeofday.
2188 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2189 which may be more usefully portable than a gettimeofday interface.
2191 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2193 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not

2204 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2206 * posix.c (scm_mknod): split the mode argument into type and perms
2207 arguments, like the extra fields returned by stat.
2209 * fports.c (scm_pipob): set the close, free and print procedures.
2210 (scm_close_pipe): new procedure.
2212 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2213 define them in boot-9.scm
2215 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2217 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
2218 wan't defined. Don't include fd.h.
2220 * Previously fd.h was regenerated whenever configure was run,
2221 forcing a couple of files to be recompiled.
2223 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
2224 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
2225 Check for _fileno as well as _file.
2227 * ioext.c: don't fd.h.
2228 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
2231 * Change the stratigy for getting information about errno
2232 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
2233 generating lists of symbols during the build process, which will
2234 not always work, include comprehensive lists in the distribution.
2235 To help keep the lists up to date, the "check_signals" and
2236 "check_errnos" make targets can be used.
2238 * configure.in: don't check for a command to extract errno codes.
2239 * Makefile.am: update file lists, remove errnos.list and errnos.c
2240 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
2241 check_errnos targets.
2242 (CLEANFILES): remove errnos.c and errnos.list, add
2243 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
2244 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
2245 * errnos.default: deleted.

2248 * cpp_err_symbols, cpp_sig_symbols: new files.
2249 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
2250 * error.c (scm_init_error): #include cpp_err_symbols instead of
2252 * posix.c (scm_init_posix): don't intern signal symbols. #include
2255 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
2257 * strop.c (scm_i_index): allow the lower bound to be equal to the
2258 length of the string, so a null string doesn't always give an error.
2260 * posix.h: new prototypes.
2261 * posix.c (scm_status_exit_val, scm_status_term_sig,
2262 scm_status_stop_sig): new functions, as in scsh. They break down
2263 process status values as returned by waitpid.
2265 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
2267 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
2268 configure doesn't know about it.
2270 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2272 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
2274 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
2275 which defines C variables with global linkage.
2277 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2279 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
2282 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
2284 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
2285 has time to check why this doesn't work well with continuations.
2287 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
2289 * Fix shell syntax error; some shells won't tolerate
2290 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
2292 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2294 * posix.c (scm_uname): throw an error if uname fails instead
2297 * error.h (scm_errno, scm_perror): obsolete prototypes removed.

2306 * acconfig.h: Removed PACKAGE.
2308 * scmconfig.h.in: Regenerated.
2310 * snarf.h: g++ says it's non-portable not to specify the first
2311 argument in a varargs declaration. I introduced the first
2312 argument by using preprocessor conditionals.
2314 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
2316 * ioext.c (scm_read_delimited_x): use RO string macros for delims.

2346 * error.h: prototype for scm_error_scm.
2348 * error.c (scm_error_scm): new procedure, reimplements scm-error
2349 in C and uses scm_error.
2351 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2353 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
2354 pointer to the Scheme variable read-hash-procedures and intern it
2355 in scm_init_read. Modify scm_read_hash_extend and
2356 scm_get_hash_procedure to use the pointer.

2360 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
2361 (SCM_KEYWORD_STYLE): defined.
2363 * read.c (scm_read_opts): add a keywords option. This isn't a
2364 boolean option, in case someone wants to add support for DSSSL
2366 Setup scm_keyword_prefix symbol.
2367 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
2369 I've left keyword support disabled by default, since it doesn't
2370 seem to break the module system and it gives R4RS standard behaviour.
2371 It can be reactivated with (read-set! keywords 'prefix).
2373 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2375 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS

2387 * read.c (scm_init_read): intitialise scm_read_hash_procedures
2388 (idea from Mikael: make it a pair so scm_permanent object only
2390 (scm_read_hash_extend): don't call scm_permanent_object.
2391 (ideas from Mikael): if chr is already in the list, replace its
2392 procedure instead of appending it again. If proc is #f, remove
2394 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
2396 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.

2425 * read.c (scm_read_token): if case_i, downcase ic before doing
2428 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2430 * configure.in: Added configuration option `guile-debug'.
2431 Configure with --enable-guile-debug if you want a bunch of extra
2432 functions used for debugging when developing Guile.
2434 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
2436 * procs.c (make-cclo): New undocumented debugging procedure: Make
2437 compiled closure with internal procedure PROC and length LENGTH.
2438 Only compiled if GUILE_DEBUG is defined.
2440 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
2442 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
2444 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
2446 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
2447 with 3 or more args internally to the evaluator.
2449 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2451 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
2452 with 3 or more args internally to the evaluator. This is mainly
2453 because we don't want to pass entry and exit points of the
2454 debug support twice, but it also seems to increase the speed of
2455 the evaluator for such calls (e. g. (+ 1 2 3)).
2457 * backtrace.c (scm_display_application): New procedure:
2458 display-application; Set fancy printing parameters individually
2459 for different types of display (backtrace, error, application).
2460 (These should of course be customizable!)
2462 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
2463 clear the CHECK-flags.
2465 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2467 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
2469 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2471 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
2472 from pairs with a GLOC in the car.
2474 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
2475 otherwise `symbol-hash' will behave badly.
2476 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
2477 we get segmentation fault!
2479 * symbols.c: Added #include "weaks.h". New functions:
2480 `builtin-bindings' and `builtin-weak-bindings'. (These will be
2481 moved to an extraneous library when we split libguile.)
2483 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2485 * filesys.c (scm_stat): stat now takes fport arguments too as
2486 documented in the manual.
2488 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2490 * debug.c (scm_single_step): Bugfix: Call continuation with
2491 scm_call_continuation instead of throwing to it.
2493 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
2495 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
2496 argument wasn't declared to be optional.
2498 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2500 * stime.c (scm_init_stime): Add feature "current-time".
2502 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
2504 * throw.h: prototype for scm_exit_status.
2505 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
2506 args to derive an exit status. Allows (quit) to work from a
2508 (scm_exit_status): new function.
2511 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2513 * eval.c (scm_deval): Removed some old code.
2514 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
2516 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
2519 * symbols.c (msymbolize): Bugfix: Must initialize property list to
2522 * procs.c: Introduce the existent C function scm_thunk_p at the
2523 Scheme level as well.
2525 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2527 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
2528 used from C to easily lookup the value of a symbol in the current
2531 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2533 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
2534 scm_init_unif in this file. This will also fix a previous problem
2537 * configure.in: Added AM_MAINTAINER_MODE
2539 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2541 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
2544 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
2546 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
2547 source files that are not always included in libguile but should
2548 have their dependencies calculated by automake. This variable is
2549 recognized by automake, no further magic is needed.
2550 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
2551 to deal exclusively with *.lo files, as it seems. The *.o files
2552 are built automatically when the corresponding *.lo file gets
2555 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
2557 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
2560 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
2562 * unif.c (scm_array_set_x): minor change to argument error checking.
2564 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
2566 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
2567 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
2568 They should only be included in the library at configure.in's
2570 (libguile_la_LDADD): Include the appropriate .lo files here.
2571 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
2572 so we know when to build them (and their .lo bretheren).
2573 * configure.in (LIBLOBJS): New substituted variable. We let
2574 configure decide which .o files to include in LIBOBJS, and then
2575 put the corresponding list of .lo files in LIBLOBJS. The latter
2576 is what we pass to libtool.
2577 * Makefile.in, configure: regenerated.
2579 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
2581 * symbols.c (scm_sysintern0): New function. Contains the core of
2582 old scm_sysintern but doesn't take a second value argument.
2583 (scm_sysintern): Now uses scm_sysintern0.
2584 (scm_sysintern_no_module_lookup): Renamed to
2585 scm_sysintern0_no_module_lookup and doesn't take a second value
2586 argument any longer.
2588 * symbols.h (scm_sysintern0: Added declaration.
2590 * options.c (scm_init_opts): Use scm_sysintern0 instead of
2591 scm_sysintern when interning option keys. Otherwise we risk
2592 destroying the values of already interned variables.
2594 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
2595 scheme-level boolean (use SCM_NFALSEP).
2597 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
2599 (scm_backtrace): New function. (C version of old function from
2600 boot-9.scm) Motivation: Make it possible to display backtraces
2601 without depending on boot-9.scm. (I'm uncertain if this
2602 motivation is good enough...)
2604 * root.h (scm_root_state): Add member the_last_stack_var.
2605 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
2607 * root.c (mark_root): Mark scm_the_last_stack_var.
2609 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
2612 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
2614 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
2615 1. mark_lazy_catch didn't mark the smob.
2616 2. Both functions above have standard variants:
2617 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
2618 free_lazy_catch --> scm_free0.
2620 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
2622 * throw.c (scm_internal_lazy_catch): New function.
2623 (scm_lazy_catch): Rewritten to use it.
2624 (scm_ithrow): Handle the new lazy catch representation.
2625 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
2626 that doesn't have a jmpbuf is a lazy catch clause.
2627 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
2628 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
2629 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
2631 (scm_init_throw): Register the new lazy-catch smob type.
2632 * throw.h (scm_internal_lazy_catch): decl for new function.
2634 * throw.c (scm_internal_catch): Doc fixes.
2636 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
2637 configure.in. Including this might cause problems if applications
2638 that link against libguile include their own copies of alloca, but
2639 if they're using autoconf, they should be adding libguile to LIBS
2640 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
2641 the copy in libguile, and things will be okay. (I think.)
2643 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2645 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
2647 strop.h: move prototypes too.
2649 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2651 * posix.c (scm_init_posix): don't intern EINTR since it's now done
2654 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
2655 etc. I deleted them from filesys.c long ago, but didn't
2656 notice they were here too (although ineffective since
2657 sys/stat.h wasn't included).
2659 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
2661 * eval.c: Don't define alloca in GCC case. gcc will automatically
2662 use __builtin_alloca if appropriate.
2664 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2666 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
2667 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
2668 that values of automatic variables are preserved. See comments
2669 for safe_setjmp for details.
2671 Change from Thomas Morgan:
2672 * variable.c: Include eq.h.
2673 (var_equal): New function.
2674 (variable_smob): Use var_equal as the discriminator for variables.
2676 * throw.c (s_throw): Remove extraneous declaration.
2678 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
2679 * eval.c: Add necessary CPP cruft to support that.
2680 * configure, Makefile.in, scmconfig.h.in: regenerated.
2682 Change from Thomas Morgan:
2683 * procprop.c (scm_procedure_properties): Convert the Scheme
2684 boolean returned by scm_procedure_p into a C boolean before using
2685 it as a condition for SCM_ASSERT.
2686 (scm_procedure_property): Likewise.
2688 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
2689 indications of Unixness.
2692 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2694 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
2696 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2698 * read.c (scm_lreadr): use scm_misc_error to improve one of the
2699 "unknown # object" error messages.
2701 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
2702 (scm_i_index) and declare it static. Add a 'direction' argument
2703 to indicate what way the search should go.
2704 (scm_i_index): throw out-of-range error instead of wrong-type-arg
2706 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
2707 strop.h: remove scm_i_index, scm_i_rindex prototypes.
2709 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2711 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
2713 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
2714 to avoid clash with various scsh forks.
2716 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
2718 The following two changes (ramap.c, throw.c) are motivated by the
2719 apparent unportability of forward declarations of static arrays of
2720 the form `static foo bar[];'.
2722 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
2723 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
2725 * throw.c (scm_throw): Moved above scm_ithrow.
2727 * options.h: Removed the extern declarations of scm_yes_sym and
2728 scm_no_sym since these are static.
2730 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2732 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
2734 * Makefile.am: remove AWK=@AWK@.
2735 Add a rule for generating errnos.list.
2736 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
2738 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
2739 don't extract errnos, just set a variable (avoids the
2740 need to recompile error.c just because configure is run.)
2742 * unif.h: update prototypes.
2743 * unif.c (scm_uniform_array_read,write): change the offset and
2744 length arguments to start and end, for consistency.
2746 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
2748 * ioext.h: update prototypes.
2749 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
2750 scm_read_line_x, it's a more general procedure using an
2751 interface from scsh. read-line and read-line! are now defined
2753 Note that the new read-line trims the terminator
2754 by default, previously it was appended to the returned string. An
2755 optional argument specifies how to process the terminator (scsh
2756 compatible). For the old behaviour: (read-line port 'concat).
2757 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
2758 returns a pair, but is converted to multiple values if the scsh
2761 socket.h: update prototypes.
2762 * socket.c (scm_recvfrom): for consistency with other procedures,
2763 take start and end as separate optional arguments.
2764 (scm_recv, scm_recvfrom): don't allow the second argument
2765 to be a size, only a buffer. Change the scheme names to
2766 recv! and recvfrom!. Don't return the buffer.
2768 * ioext.h, posix.h: move prototypes too.
2769 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
2770 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
2771 "read.h" and "unif.h".
2772 * ioext.c: include "chars.h"
2774 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
2776 * dynl.c: The dynamic linking and module registration functions
2777 are now defined even when dynamic linking is not available for the
2778 host system. Some of their functionality can be done without
2779 dynamic linking; when it's really needed, they throw errors.
2781 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
2783 * configure.in: Only define DYNAMIC_LINKING when one of the system
2784 dependent functions is detected.
2785 * dynl.c (scm_dynamic_func): New function to get the address of a
2786 function in a dynamic object.
2787 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
2788 produced by scm_dynamic_func as the thing to call.
2790 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
2792 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
2793 (scm_register_module_xxx, scm_registered_modules,
2794 scm_clear_registered_modules): New functions.
2796 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
2798 * symbols.c (scm_sysintern): Renamed to
2799 scm_sysintern_no_module_lookup.
2800 (scm_sysintern): New function to take the place of the old
2801 scm_sysintern. It uses the current toplevel lookup closure to give
2802 the symbol its value. This is a temporary hack to put packages
2803 like gtcltk into their own module.
2804 (scm_can_use_top_level_lookup_closure_var): New variable to tell
2805 us whether `scm_top_level_lookup_closure_var' has been initialized
2807 * eval.c (scm_init_eval): Set it.
2809 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
2811 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
2812 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
2814 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
2816 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
2817 scm_sys_dup): deleted: FD capability will be added to other
2819 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
2820 scm_fd_free, fd_smob, scm_intern_fd.
2821 (scm_open): renamed from scm_sys_open. Return a port instead of
2822 an FD object. Make the mode argument optional.
2823 (scm_sys_create): deleted, it's just a special case of open.
2824 (scm_init_filesys): move interning of constants O_CREAT etc.,
2825 here (were previously using SCM_CONST_LONG macro).
2826 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
2828 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
2829 include "fports.h" and <stdio.h>
2830 (scm_stat, scm_select): don't support FD objects.
2832 * error.h: adjust scm_syserror_msg prototype.
2833 * error.c (scm_syserror_msg): take an extra argument for errno.
2834 Using the global value didn't always work, since it could be
2835 reset by procedure calls in the message or args arguments.
2837 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
2838 I don't understand why the check was there (and what about the
2841 * strop.c (scm_string_copy): allow shared substrings to be copied.
2843 * unif.h: corresponding change to prototypes.
2844 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
2845 recognize two new optional arguments: offset and length. Allow
2846 the port argument to be an integer (file descriptor, for scsh).
2847 Include <unistd.h> for "read" prototype.
2849 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2851 * socket.c: don't include filesys.h.
2853 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
2855 * Makefile.am: add AWK=@AWK@ (?)
2857 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
2859 Add a rule to generate errnos.c from errnos.
2860 * error.c (scm_init_error): include errnos.c.
2861 * errnos_cnvt.awk: new file, converts the list of errno codes to
2863 * errnos_get.c: new file.
2864 * errnos.default: new file, contains errnos to try if they can't
2865 be extracted from errno.h.
2866 * configure.in: if using GCC, try and extract errno codes from
2870 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
2872 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
2873 * Makefile.am: Made libguile into a libtool library.
2874 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
2875 Set libtool_libs to indicate that libguile is a libtool library.
2876 See guile/ChangeLog for details.
2877 * .cvsignore: ignore "*.lo", the libtool library objects.
2879 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2881 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
2882 use htons in getservbyport argument.
2884 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2886 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
2887 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
2890 * objprop.c (scm_object_property): No need to take the CDR of the
2891 value returned by scm_object_properties, since Aug 20 change.
2893 * configure.in: When checking for struct linger, #include
2894 <sys/types.h> as well as <sys/socket.h>. I've never known
2895 <sys/types.h> to cause any portability problems, and Solaris's
2896 <sys/socket.h> needs it.
2897 * configure: Rebuilt.
2899 I think the Sun compiler has chosen a perverse way to interpret
2900 ANSI declarations combined with K&R definitions. We'll
2901 appease it a little bit. But when it invades France, we fight.
2902 * print.c (scm_iprlist): Change 'tlr' argument to an int.
2903 * print.h (scm_iprlist): Here too.
2904 * numbers.c (scm_divbigdig): Change definition to match
2905 declaration in numbers.h.
2906 * unif.c (scm_makflo): Change definition to match declaration in
2909 * init.c (scm_boot_guile): Don't return the value of
2910 scm_boot_guile_1. This function doesn't return a value;
2911 scm_boot_guile_1 doesn't return a value (or return at all).
2913 * eval.c (unmemocopy): Add a semicolon to appease the Sun
2916 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
2917 compile. I have a feeling this function is a bad idea anyway ---
2918 one should always test for features, not systems.
2920 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
2921 semicolons. Only pure luck kept this from being noticed earlier.
2923 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
2925 * socket.c (scm_recvfrom): Added missing semicolon.
2927 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2929 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
2930 the buffer and start and end positions for scsh networking
2933 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
2935 * configure.in: Revert previous change to this file; the problem
2936 is due to transient automake weirdness.
2937 * configure: Rebuilt.
2939 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
2940 PLUGIN/guile.libs. configure generates the latter from the former.
2941 * Makefile.in: Rebuilt.
2943 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
2944 need this if we install scripts, like guile-snarf.
2945 * configure: Rebuilt.
2947 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
2949 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
2951 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
2953 * socket.c (scm_addr_vector): fix faulty scm_listify.
2955 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
2957 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
2958 style block comment is no longer considered an error.
2960 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
2962 * PLUGIN/guile.libs.in: New file.
2963 * PLUGIN/guile.libs: Removed from repository.
2964 * configure.in: Create PLUGIN/guile.libs from
2965 PLUGIN/guile.libs.in. This is for including additonal libraries
2966 needed for dynamic linking.
2967 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
2968 instead of PLUGIN/guile.libs.
2970 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
2972 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
2974 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
2975 occurrences of the given element from the list, not just the
2976 first. This is how the Emacs Lisp functions behave, how the
2977 analogous Common Lisp functions behave, and (I believe) how the
2978 older Maclisp functions worked. I realize that this change may
2979 break code, but it seemed better to break it before the Guile
2982 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
2983 Their prototypes were already present in gc.h, but they weren't
2985 (scm_init_storage): Initialize scm_protects.
2986 * root.c (scm_protects): New element of scm_sys_protects.
2988 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
2990 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
2992 * libguile.h: Added #include "libguile/net_db.h".
2994 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
2995 30 change. That file is only meant for communication between the
2996 configuration process and load.c. If code linked against libguile
2997 wants to get at the paths mentioned in libpath.h, it can call
2998 functions declared in load.h.
3000 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3002 * libguile.h: Removed #include "libguile/fdsocket.h"
3004 * net_db.c: Added #include <sys/socket.h>.
3006 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3008 * filesys.c (scm_input_waiting_p): use select in preference to
3009 FIONREAD, since the latter doesn't detect EOF.
3010 Throw error if neither select nor FIONREAD available.
3012 * socket.c (scm_connect): take a port, not a fd object.
3013 (scm_fill_sockaddr): throw an error if fam is not recognised.
3014 (scm_bind): use scm_fill_sockaddr.
3015 (scm_listen): take a port, not a fd object.
3016 (scm_accept): take and return a port. return #f in the car if
3017 address can't be got
3018 (scm_sock_fd_to_port): new procedure.
3019 (scm_socket): use scm_sock_fd_to_port.
3020 (scm_addr_vector): throw error if unrecognised address type.
3021 take an extra argument with the calling procedure name.
3022 (scm_getsockname): take a port. return #f if address can't be got.
3023 (scm_getpeername): take a port. return #f if address can't be got.
3024 (scm_recvfrom): take a port. return #f for address component if can't
3026 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3027 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3029 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3031 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3032 use separate data pointers, to allow them to be designed
3033 independently and reused.
3034 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3035 Renamed from catch_body, catch_handler, and uncaught_throw; made
3037 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3039 (scm_catch): Use the above.
3040 (scm_throw): Don't bother printing a message for an uncaught
3041 throw; we establish a default handler in init.
3042 * throw.h (scm_internal_catch): Prototype updated.
3043 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3045 (struct scm_body_thunk_data): New structure, used as data
3046 argument to scm_body_thunk.
3047 * init.c (struct main_func_closure): New structure, packaging up
3048 the data to pass to the user's main function.
3049 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3050 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3051 scm_internal_catch to establish a catch-all handler, using
3052 scm_handle_by_message. This replaces the special-case code in
3054 (invoke_main_func): Body function for scm_internal_catch; invoke
3055 the user's main function, using the main_func_closure pointer to
3056 decide what to pass it.
3057 * root.c (struct cwdr_body_data): Remove handler_proc member.
3058 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3059 (cwdr_handler): Removed.
3061 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3063 * socket.h (SCM_P): update bind prototype.
3064 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3065 include "feature.h".
3066 (scm_socket): return a port, not a file descriptor object.
3067 include "fports.h" and <unistd.h>
3068 (scm_bind): take a port, not a file descriptor object.
3069 take an extra argument for address args.
3071 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3072 INADDR_NONE, INADDR_LOOPBACK.
3074 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3076 * init.c: include net_db.h and not fdsocket.h.
3077 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3079 * Makefile.am: corresponding changes.
3080 * socket.h: renamed from fdsocket.h, fix names.
3081 * net_db.h: renamed from socket.h, fix names.
3082 * socket.c: renamed from fdsocket.c.
3083 remove _sys from procedure names.
3084 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3085 add "socket" to features list.
3086 * net_db.c: renamed from socket.c.
3087 remove _sys from procedure names.
3088 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3089 add "net-db" to features list.
3090 include "net_db.h". don't include <sys/socket.h> or
3093 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3095 * tags.h (scm_tags): Removed comma at end of last enumerator.
3097 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3099 Don't use GCC extensions to allocate space for debugging frames.
3100 (Here he goes again! Why do we put up with this?!)
3101 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3102 an scm_debug_info structure, not an in-line array of them. Add
3103 'info' member, to say how many vect elements we've used, for eval
3105 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3106 a new variable debug_info_end to mark the end of vect, instead of
3107 the address of the 'info' pointer itself.
3108 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3109 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3110 (SCM_APPLY): Explicitly allocate space for debug.vect.
3111 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3112 * stacks.c: Adjusted for new debug frame structure.
3113 (RELOC_INFO, RELOC_FRAME): New macros.
3114 (stack_depth, read_frames): Use them, and new scm_debug_frame
3115 element 'info', instead of magically knowing that eval frames have
3116 an info pointer sitting after vect.
3117 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3119 (scm_init_stacks): Formatting tweaks.
3121 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3123 Give GCC more control flow information, so it can be sure that
3124 variables aren't used uninitialized.
3125 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3126 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3127 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3128 scm_misc_error): Tell GCC that these functions never return.
3129 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3130 out the field type, call abort if SCM_ASSERT returns, to placate
3132 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3133 scm_wta ever returns. We can't handle this case anyway, and this
3134 gives the optimizer more information.
3135 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3136 scm_wta ever returns.
3138 In some cases, the code is fine, but GCC isn't smart enough to
3139 figure that out; this usually happens when one variable is only
3140 initialized and used when a particular condition holds true, and
3141 we know that condition will never change within a given invocation
3142 of the function. In this case, we simply initialize the variables
3143 to placate the compiler, hopefully to a value which will cause a
3144 crash if it is ever actually used.
3145 * print.c (scm_iprin1): Initialize mw_pos.
3146 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3147 * throw.c (scm_ithrow): Initialize dynpair.
3148 * unif.c (scm_uniform_vector_ref): Initialize cra.
3149 * struct.c (init_struct): Initialize prot.
3150 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3152 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3153 if EXPR contains no expressions.
3155 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3157 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3158 cause an infinite loop (???). So much for the algebraic
3159 equivalency of variable-sized arrays and alloca...
3161 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3163 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3164 a SCM boolean, not a C boolean.
3166 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3168 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3169 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3170 rules for raising scm_mtrigger. Previously, unfortunate but not
3171 unlikely circumstances could result in almost constant invokation
3172 of the gc. Now, this situations should be less likely, but they
3173 are not prevented completely.
3175 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3177 * numbers.c (scm_fuck): Procedure removed; looks like old test
3179 * numbers.h: Prototype removed.
3181 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3183 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3184 array to a pointer, to match my Nov 21 change in eval.c.
3186 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3188 * libguile.h: Added #include "libguile/backtrace.h", #include
3189 "libguile/stacks.h".
3191 * strings.c (scm_string scm_make_string scm_string_ref
3192 scm_string_set_x scm_string_equal_p scm_string_append):
3193 Bugfix according to scm patch from Aubrey Jaffer:
3194 Corrected long-standing
3195 (not (eqv? (integer->char 128)
3196 (string-ref (make-string 1 (integer->char 128)) 0)))
3197 bug found by John Kozak <jk@noontide.demon.co.uk>.
3199 * strports.c, strports.h: Make scm_eval_0str return the value of
3200 the last expression evaluated (previously, it returned void).
3202 * strports.c, strports.h: New function: scm_read_0str. Does what
3205 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3207 * simpos.c (scm_getenv): return #f if string can't be found in the
3208 environment instead of throwing an exception, for compatibility
3209 with numerous other systems.
3211 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3213 * Makefile.am (.c.x): Use guile-snarf.
3214 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
3216 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
3218 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3220 * backtrace.c (scm_display_error_message): Made non-static, and
3221 renamed from display_error_message.
3222 * backtrace.h (scm_display_error_message): Added extern decl.
3223 * throw.c (uncaught_throw): Use it to display the error message.
3225 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
3227 * inet_aton.c: Use #if 0, not #ifdef 0.
3229 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
3231 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
3232 to convert the returned value.
3233 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
3234 the offset argument.
3236 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3238 Add new interface to catch/throw, usable from C as well as
3240 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
3241 (scm_internal_catch): New function, replaces...
3242 (scm_catch_apply): Deleted.
3243 * throw.c (scm_catch_apply): Deleted; replaced with a more general
3244 mechanism which is a bit more code, but can be used nicely from C
3245 and implement the Scheme semantics as well.
3246 (scm_internal_catch): This is the replacement; it's named after
3247 the analogous function in Emacs.
3248 (scm_catch): Reimplemented in terms of the above.
3249 (struct catch_body_data, catch_body, catch_handler): New
3250 functions, used by scm_catch.
3251 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
3252 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
3253 support for new cwdr.
3255 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
3258 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
3260 * acconfig.h: Added DYNAMIC_LINKING symbol.
3261 * configure.in: Add option and checks for dynamic linking.
3262 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
3263 dynl.h: New files for dynamic linking support.
3264 * Makefile.am (libguile_a_SOURCES):
3266 (modinclude_HEADERS): Added "dynl.h".
3267 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
3269 * init.c (scm_boot_guile_1): Call
3270 scm_init_dynamic_linking to initialize dynamic linking support.
3272 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
3274 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
3275 (as we Schemers say). It needs to be global, so that I can tweak
3276 it for the proper operation of unexec.
3277 (scm_boot_guile_1_live): New variable, see above.
3279 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
3281 * guile-snarf.sh: Removed.
3282 * PLUGIN/guile.libs: Added dependency for -lm.
3283 * acinclude.m4: Renamed from aclocal.m4.
3284 * PLUGIN/greet: Removed.
3285 * Makefile.am, aclocal.m4: New files.
3286 * configure.in: Updated for Automake.
3288 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
3290 * eval.c (scm_definedp): Use top_level_lookup_closure_var
3291 and not top_level_lookup_thunk_var.
3293 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
3295 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
3297 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
3299 * eval.c (scm_definedp): Incompatibly changed to be a builtin
3300 Scheme function, instead of syntax. Single argument is now a
3303 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3305 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
3306 scm_ra_divide): Properly terminate statements passed as arguments
3307 to IVDEP macros. (Thanks to Bernard Urban.)
3309 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
3310 with non-constant sizes. (Thanks to Bernard Urban.)
3312 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3314 It's an "eval closure", not an "eval thunk." A thunk is a
3315 function of no arguments.
3316 * root.h (struct scm_root_state): Renamed
3317 top_level_lookup_closure_var from top_level_lookup_thunk_var.
3318 (scm_top_level_lookup_closure_var): Renamed from
3319 scm_top_level_lookup_thunk_var.
3320 * root.c (mark_root): Uses changed.
3321 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
3322 * init.c (scm_start_stack): Uses changed.
3323 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
3324 Change scheme-visible name to *top-level-lookup-closure* from
3325 *top-level-lookup-thunk*.
3327 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
3329 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
3330 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
3332 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
3334 * gc.c (struct scm_heap_seg_data): Doc fixes.
3336 * gc.c (scm_gc_sweep): Empty all segments' freelists before
3337 sweeping. Then, prepend each segment's free cells to its
3338 freelist, rather than wiping out the old value. (Thanks to Marius
3341 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
3342 scm_check_freelist, scm_debug_newcell): New functions and
3343 variables, for debugging freelist problems.
3344 * pairs.h (SCM_NEWCELL): New debugging version added.
3345 * gc.h (scm_debug_newcell): Added extern declaration, used by
3346 debugging version of SCM_NEWCELL.
3348 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3350 On some systems <libc.h> conflicts with <unistd.h>, and should not
3351 be #included at all.
3352 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
3353 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
3354 * configure.in: Call it.
3355 * posix.c, filesys.c: Use its results to decide whether or not to
3357 * configure, scmconfig.h.in: Rebuilt with autoconf and
3360 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
3362 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
3363 pointer to the stdio stream before calling scm_setbuf0, so the
3364 latter will be able to retrieve it. I'm surprised this didn't
3365 segfault earlier. (Thanks to Christopher Lee.)
3367 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3369 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
3372 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3374 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
3375 number of stack narrowing specifier pairs. The first specifier in
3376 a pair controls inner border, the second the outer border. A
3377 number means cut that number of frames, a procedure object means
3378 cut until that object is found in operator position in a frame.
3380 * root.c (cwdr): Bugfix.
3382 * read.c: Recording of positions disabled by default.
3384 * procs.c (scm_closure_p): New function.
3386 * posix.c (scm_tmpnam): New function.
3388 * load.c: Added #include "throw.h".
3389 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
3392 * load.c, load.h (scm_read_and_eval_x): New function.
3394 * eval.c: Renamed debug option "deval" to "debug".
3396 (scm_eval_x): `eval!' is no longer accessible from the scheme
3397 level. Motivation: We can't allow operations which introduce
3398 glocs into the scheme level. Guile's type system can't handle
3399 these as data. Use `eval' or `read-and-eval!' as replacement.
3401 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
3402 SCM_CONSP since this is a macro!; Set vframe.prev to
3403 scm_last_debug_frame instead of 0. In this way we can look
3404 "above" the virtual start stack frame if we wish.
3405 (scm_debug_hang): New function: Useful for debugging Guile in
3406 certain tricky situations. Will probably be removed later...
3408 * debug.h: Changed semantics of debug option "backtrace". This
3409 option now only indicates whether we want automatic backtrace at
3412 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3414 * ports.c: #include "filesys.h"
3415 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
3417 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
3418 Motivation: This is system specific code which is related to file
3419 I/O. It also may use select. Added code by Gary Houston to
3420 detect presence of character in stdio buffers.
3422 * libguile.h: #include "libguile/libpath.h"
3424 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
3425 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
3426 SCM_SITE_DIR; Install libpath.h among the other include files.
3428 * load.c, load.h (scm_sys_package_data_dir): New function.
3430 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3432 * stacks.h: Bugfix: Don't use tail-array length field as stack
3433 length field! This screwed GC.
3435 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3437 * _scm.h: Added #ifndef around definition of macros min and max.
3439 * __scm.h: Added hooks for threads to plugin to in ints protection
3440 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
3441 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
3442 the main code in these macros duplicated and spread over multiple
3443 files. Renamed SCM_THREADS_SWITCHING_CODE ->
3444 SCM_THREAD_SWITCHING_CODE.
3446 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
3448 * snarf.h: New file.
3449 * guile-snarf.sh: New file.
3450 * Makefile.in (inner_h_files): Added snarf.h
3451 (ancillary, install, uninstall, distclean): Added actions for
3453 (.c.x): Use guile-snarf.
3454 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
3455 (gen_c_files): Note that these depend on guile-snarf.
3456 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
3457 now in "snarf.h". Added #include "snarf.h" to get them.
3458 * libguile.h: Added #include "snarf.h".
3459 (Patches applied and tweaked by Jim Blandy.)
3461 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
3463 * socket.c: Use K&R style declaration for 'close'; the GNU coding
3464 standards suggest against providing prototypes for system
3465 functions. Thanks to Greg Troxel.
3467 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3469 * strports.c (scm_eval_0str): New function.
3470 #include "read.h", to get prototype for scm_read.
3471 * Makefile.in (strports.o): Update dependencies.
3472 * strports.h: New prototype.
3474 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
3475 scheme name from "int?" to "integer?". It seems to do the job.
3476 * numbers.h: Rename prototype too.
3477 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
3480 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
3481 scm_num_eq_p): Rename these according to R4RS conventions: call
3482 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
3483 to making libguile R4RS compliant without ice-9...
3485 * load.c (scm_sys_search_load_path): Search for files under all
3486 extensions listed in the %load-extensions variable. If FILENAME
3487 is absolute, return it unchanged, without searching the load path.
3488 (scm_loc_load_extensions): New variable, pointing to
3489 %load-extensions' value cell.
3490 (scm_init_load): Initialize it, and the value it points to.
3491 (scm_primitive_load_path): Improve error reporting.
3493 * load.c (scm_loc_load_hook): New variable, pointing to value cell
3494 of new Scheme variable %load-hook.
3495 (scm_primitive_load): Apply %load-hook to filename.
3497 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
3499 * configure.in: add tests for figuring out whether buffered data
3500 is available in a FILE structure, which is needed by char-ready.
3502 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
3505 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
3506 exceptions using misc_error instead of syserror. It seems a bit
3507 odd to throw an exception if a string can't be found in the
3508 environment, but it's consistent with open-file, stat etc.
3509 (simpos.h): remove sys_ from getenv.
3511 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
3512 occurs, throw an error instead of returning errno. Return value
3514 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
3516 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
3518 * filesys.c (scm_stat2scm): derive file type and permissions from
3519 the stat mode and append them to the returned vector.
3520 There isn't much overhead in doing this and it avoids the need to
3521 work with S_IRUSR et al. in Scheme.
3522 Define symbols scm_sym_regular etc.
3523 (scm_init_filesys): don't intern S_IRUSR etc.
3525 * load.c: change s_try_load and s_try_load_path to s_primitive_load
3526 and s_primitive_load_path.
3528 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
3530 * error.h: don't declare error symbols. prototype for scm_misc_error.
3532 * stackchk.c (scm_stack_overflow_key): defined here instead of in
3535 * error.c: use SCM_SYMBOL to set up error keys.
3536 scm_misc_error: new procedure.
3538 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3540 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
3541 between `#!' and `!#' is ignored.
3542 (skip_scsh_block_comment): New function.
3544 * feature.c (scm_set_program_arguments): New argument, FIRST.
3545 * feature.h: Update prototype.
3546 * init.c (scm_boot_guile_1): Pass new argument to
3547 scm_set_program_arguments.
3549 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3551 * init.c (scm_start_stack): Don't initialize scm_progargs here.
3552 (scm_boot_guile): Call scm_set_program_arguments here, later than
3553 the old initialization.
3555 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
3556 initialization procedure.
3557 - Delete in, out, err arguments; there are other perfectly good
3558 ways to override these when desired.
3559 - Delete result argument; this function shouldn't ever return.
3560 - Rename init_func argument to main_func, for less confusion.
3561 - Delete boot_cmd argument; main_func is more general.
3562 -Add 'closure' argument, to help people pass data to main_func
3563 without resorting to global variables.
3564 - Abort if reentered; don't bother returning an error code.
3565 - Call scm_init_standard_ports to set up the default/current
3566 standard ports; no need to pass them to scm_start_stack.
3567 - Remove code to evaluate the boot_cmd, and start the repl; let
3568 the user do something like that in main_func if they want.
3569 - Remove code to package up a return value; main_func can do any
3571 - Call exit (0), instead of returning.
3572 (scm_start_stack): Don't initialize the I/O ports here; that's
3573 weird. Delete in, out, err arguments. Move guts to
3574 scm_init_standard_ports, scm_stdio_to_port.
3575 (scm_init_standard_ports): New function, to set up current and
3576 default standard ports.
3577 (scm_start_stack, scm_restart_stack): Make these static.
3578 * init.h (scm_boot_guile): Adjust declaration.
3579 (scm_start_stack, scm_restart_stack): Remove externally
3580 visible declarations for these.
3581 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
3583 * fports.c (scm_stdio_to_port): New function. Its guts used to be
3584 written out several times in scm_start_stack.
3585 * fports.h: New declaration for the above.
3587 * feature.c (scm_set_program_arguments): New function.
3588 * feature.h: New declaration for the above.
3590 * ports.c: Formatting tweak.
3592 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
3594 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
3595 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
3596 for obtaining the address of a car or cdr field. Motivation:
3597 &SCM_CXR make assumptions about the internal structure of the
3600 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
3601 Motivation: see SCM_CXRLOC.
3603 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
3604 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
3605 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
3606 Motivation: Safer use. Some other macros are defined in terms of
3607 these operations. If these are defined using the SCM_SETCXR
3608 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
3609 to inefficiency and an <e1> with side-effects could potentially
3610 break. Also, these particular operations are heavily utilized in
3611 the garbage collector. In unoptimized code there will be a
3614 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
3615 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
3616 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
3617 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
3618 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
3619 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
3620 vports.c: Cleaned up use of pairs: Don't make any special
3621 assumptions about the internal structure of selectors and
3622 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
3623 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
3624 (Among other things, this change makes it easier to build Guile
3625 with certain compilers which have problems with casted lvalues.)
3627 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3629 * stacks.c: Improve selection of relevant stack frames when making
3630 a stack object. Introduce one level of indirection in the stack
3631 object to make it possible to "narrow" to a certain region of the
3632 stack. This facilitates making use of more clever algorithms (not
3633 implemented) for selecting relevant frames and gives a cleaner
3634 design since selection of frames can be done independently of
3635 extraction of frames from the real stack.
3636 (scm_stack_id): Also take #t as argument which means look at
3639 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
3640 Turn n_tail into an integer directly representing current number
3641 of frames in stack. Add field tail.
3643 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
3645 * debug.c (scm_make_memoized): Made it available at scheme level.
3646 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
3647 SCM_NIMP before applying heavier predicates in argument checking.
3648 (scm_local_eval): Also take memoized object as argument.
3650 * backtrace.c (scm_display_error): Just a safety measure: Stacks
3651 aren't created with zero length, but should such a strange
3652 creature suddenly turn up...
3654 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
3656 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
3657 `del', for the sake of C++ compilers. (Patch applied by JimB.)
3659 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
3661 * variable.c (scm_make_variable): Make the name hint optional, as
3663 (anonymous_variable_sym): Renamed from variable_sym. All uses
3666 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
3667 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
3668 of scm_primitive_load_path was also changed to
3669 "primitive-load-path", from "%try-load-path". Callers changed.
3670 We'd like to respect the convention that a function named
3671 "try-mumble" should behave just like the function called "mumble",
3672 but return #f instead of signalling some error.
3673 * load.h: Rename prototypes.
3675 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3677 * print.c (make_print_state, grow_print_state), print.h: Modified
3678 the print state representation: Don't use a tail array for
3679 recording of circular references. Resizing of the print state
3680 structure invalidates the print state pointer. To avoid passing
3681 around an indirect print state reference to all printing
3682 functions, we instead let the print state reference a resizable
3685 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
3687 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
3688 Don't crash when passed an improper list terminated by a
3689 non-immediate value.
3691 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
3693 Allocate data for structures on an eight-byte boundary, as
3694 required by the tagging system.
3695 * struct.c (alloc_struct): New function.
3696 (scm_make_struct, scm_make_vtable_vtable): Call it.
3697 * struct.h (scm_struct_n_extra_words): Bump to 3.
3698 (scm_struct_i_ptr): New "field".
3699 * gc.c (scm_gc_sweep): When we need to free the data, use the
3700 information stored by alloc_struct to find the beginning of the
3701 block allocated to the structure, so we can free it.
3703 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3705 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
3708 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
3709 (scm_debug_info): New member: id.
3711 * stacks.c: Stacks are now represented as structs; Stacks have an
3712 id given to them by `start-stack'.
3713 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
3715 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
3716 Changed stack representation.
3718 * debug.c (scm_procedure_name): Try procedure property `name' for
3719 compiled closures aswell.
3721 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
3723 * eval.c: scm_i_name moved to gsubr.c
3724 (scm_m_define): Record names of all kinds of procedure
3725 objects. (Earlier, only closures were recorded.)
3727 * procprop.h: Added declaration of scm_i_name.
3729 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
3730 (scm_make_gsubr): Record names of compiled closures.
3732 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3734 * debug.c, debug.h: Removed obsolete code.
3736 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
3737 stacks.c: Renamed regs --> scm_contregs.
3739 * print.c (scm_free_print_state): Cleanup print state before
3740 returning it to pool. It is better to do it here than in
3741 scm_prin1 since scm_prin1 is called often.
3743 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
3744 s_set_source_property_x): Check that first argument is a pair or a
3747 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
3748 scm_i_line, scm_i_column and scm_i_breakpoint global.
3750 * init.c: Added #include "backtrace.h" and #include "stacks.h".
3751 (scm_boot_guile_1): Added calls to scm_init_backtrace and
3754 * debug.h: Added debug object smob declaration and macro
3757 * configure.in: Build with backtrace.o and stacks.o if debug
3760 * Makefile.in: Added entries for new files: backtrace.c,
3761 backtrace.h, stacks.c and stacks.h.
3763 * symbols.c (scm_sym2ovcell): Fixed documentation.
3765 * _scm.h (min, max): Added.
3767 * async.c: Moved `min' macro to _scm.h.
3769 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
3770 SCM_BACKTRACE_INDENT.
3772 * eval.c: Added new debug options `maxdepth' and `indent'.
3774 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
3776 * print.h: Added selector SCM_PRINT_STATE.
3778 * print.c: New functions: scm_make_print_state,
3779 scm_free_print_state.
3781 * print.h: Added declarations for scm_make_print_state,
3782 scm_free_print_state.
3784 * debug.c (scm_m_start_stack): New acro.
3786 * debug.h: Small cleanup.
3788 * init.c (scm_boot_guile_1): Moved scm_init_debug below
3791 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

3816 More prototype-related changes from Marius Vollmer:
3817 * gdb_interface.h: Wrapped header file in #ifdef/#endif
3818 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
3819 * ports.h (ptobfuns): Added prototypes. This means some casting in
3821 * fports.c: Added casts for initializations, since the functions
3822 are defined to take FILE * as their stream argument, not SCM.
3823 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
3824 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
3825 to `char *str_data' to conform to prototype.
3827 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
3829 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
3831 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
3833 * stime.c, stime.h: use SCM_P method.
3835 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
3837 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
3838 be given at least two arguments. Insist that lst's last element
3839 be a list, but don't make any requirements of its predecessors.
3841 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
3843 * eval.c (scm_nconc2last): Revert last change; there seems to be
3844 other stuff going on here.
3846 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
3848 * eval.c (scm_nconc2last): Make sure that each element of lst
3849 (which is a list of argument lists, except for the tail) is a
3850 proper list, i.e., finite and terminated by '().
3852 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
3854 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
3857 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
3858 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
3861 * vectors.c (scm_make_vector): Fill vectors with the undefined
3862 value, to help make Guile Scheme code more portable to other
3865 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
3866 * symbols.h, tags.h: Doc fixes.
3868 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
3870 * async.c (scm_take_signal): Doc fixes.
3872 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
3874 * numbers.c (scm_divbigint): When the remainder is zero, we don't
3875 want to subtract it from the modulus; we just want to leave it
3878 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
3880 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
3883 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
3885 * throw.c (scm_catch_apply): Finished implementation of
3888 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
3890 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
3892 (scm_init_filesys): set "i/o-extensions" feature.
3895 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
3897 * Makefile.in (root.o): Correct dependencies.
3899 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
3901 * Makefile.in: Added dependency entry for root.o.
3903 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
3904 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
3906 * init.c (scm_start_stack): Set initial root continuation number
3909 * procs.c: New function: scm_thunk_p.
3911 * procs.h: Added declarations of scm_thunk_p.
3913 * root.c: Renamed `call-with-new-root' -->
3914 `call-with-dynamic-root'.
3915 (cwdr): Removed allocation of new root state. This should be done
3916 separately by use of scm_make_root.
3917 (scm_apply_with_dynamic_root): New function: Does what it
3918 sounds like. Needed when spawning threads.
3920 * root.h: Added member last_debug_frame to root state.
3921 Added #include "libguile/debug.h"
3923 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
3924 arguments. The motivation is that code in root.c needs catch
3925 functionality, and we want to avoid code duplication.
3926 New functions: scm_catch, scm_lazy_catch. These are wrappers for
3927 scm_catch_apply. scm_lazy_catch is intended to introduce catch
3928 handlers that run without popping the stack into the dynwind
3931 * throw.h: Added prototypes for scm_catch_apply and
3934 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3936 * root.h (scm_root, scm_set_root): Decouple thread support details
3937 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
3938 SCM_SET_THREAD_LOCAL_DATA.
3940 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
3941 and tortoise scanning loop.
3943 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
3945 * Makefile.in: Rebuild dependencies.
3947 * libguile.h: #include "libguile/print.h" before "smob.h", since
3948 the latter uses the print_state structure.
3950 * throw.c (scm_ithrow): Use the correct variable when checking to
3951 see if a given element of scm_dynwinds is a valid catch.
3953 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
3954 structure, abort; don't just silently ignore the garbage.
3956 * _scm.h: #include "print.h" here, since it seems to be used just
3958 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
3959 strports.c, unif.h: Don't #include "print.h".
3961 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3963 * feature.h (scm_loc_features): Removed external declaration.
3964 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
3966 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3968 * feature.c (scm_init_feature): Added threads feature (needs to be
3969 initialized here, since features doesn't exist when
3970 scm_init_threads is called).
3972 * libguile.h: Added #include "libguile/../threads/threads.h".
3973 (This is a kludge to get thread support working. This should be
3976 * configure.in, acconfig.h: Added flags for thread support.
3978 * scmsigs.c: Define `signal' to be `pthread_signal' if using
3981 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
3982 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
3985 * _scm.h: Added conditional #include "threads.h"
3987 * __scm.h (SCM_ASYNC_TICK): Added call to macro
3988 SCM_THREADS_SWITCHING_CODE.
3990 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
3991 allocate the basic dynamic root object.
3992 (scm_boot_guile): Added call to scm_init_root.
3994 * root.c, root.h: Added root smob.
3995 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
3996 functions: Implements dynamic roots mostly according to spec in
3997 SCM manual. Main difference is that the second argument is a
3998 throw handler rather than an error "thunk".
4000 * root.h: Added declaration of scm_init_root.
4002 * root.c: Added #include "genio.h", #include "smob.h", #include
4003 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4005 (scm_init_root): Added #include "root.x".
4007 * throw.c: Added #include "stackchk.h"
4008 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4009 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4010 can be used in scm_call_with_new_root; Added reenabling of stack
4011 checking when catching a throw.
4013 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4015 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4017 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4018 element is not found, as per R4RS.
4020 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4022 * list.c: Doc fixes throughout.
4024 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4026 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4027 declare the char * to be const. Avoids a warning in rgx.c.
4029 * ports.h: spelling fix.
4031 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4034 * load.c (scm_sys_try_load_path): throw an error if file not found
4035 (like it says it in NEWS).
4037 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4039 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4040 PROPS slot to '(), not #f; it's an empty alist.
4042 * throw.h, throw.c: Use SCM_P instead of #if hair.
4044 Remove special support for uncaught throws; see throw.c for
4046 * throw.c (uncaught_throw): New function.
4047 (scm_ithrow): Call uncaught_throw if we don't find a throw
4048 target; don't mess with scm_bad_throw_vcell.
4049 (scm_bad_throw_vcell): Variable deleted.
4050 (scm_init_throw): Don't initialize it.
4052 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4055 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4057 * numbers.c (scm_istr2int): If the number is short (as most
4058 numbers are), just call scm_small_istr2int to deal with it.
4059 (scm_small_istr2int): New function, created by un-#ifdefing the
4060 non-bignum version of scm_istr2int and renaming it.
4062 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4064 * load.c (scm_sys_try_load): don't check whether value returned
4065 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4066 Change the Scheme name from %try-load to primitive-load.
4068 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4069 Can avoid passing a message, allowing it to be derived in the
4070 error handler (e.g., if we want to throw to the key both from
4073 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4075 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4076 references now have a new appearance which is more compact and
4077 also gives a clue about what the target of the reference is.
4078 By setting parameters in the print state, more fancy printing can
4079 be achieved. This is used by the (not yet commited) backtrace
4082 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4084 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4087 * print.c: Added #include "struct.h". Removed function
4090 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4091 scm_iprin1. Removed prototype for scm_prlist.
4093 * arbiters.c (prinarb),
4094 async.c (print_async),
4095 debug.c (prindebugobj, prinmemoized),
4096 eval.c (prinprom, prinmacro),
4097 filesys.c (scm_fd_print, scm_dir_print),
4099 mallocs.c (prinmalloc),
4100 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4101 smob.h (scm_smobfuns),
4102 srcprop.c (prinsrcprops),
4104 unif.c, unif.h (scm_raprin1, rapr1),
4105 variable.c (prin_var): Changed argument `int writing' to
4106 `scm_print_state *pstate'.
4108 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4109 that it will be called before scm_init_print.
4111 * print.c (scm_prin1): Print states are now allocated when calling
4112 scm_prin1 and then passed around to all printing functions as an
4113 argument. A cache `print_state_pool' enables reuse of print
4115 (scm_make_print_state): New function.
4116 (scm_iprin1): Adaption to print states.
4117 (scm_iprlist): An initial "hare and tortoise" scan brings down
4118 time complexity to O (depth * N). (Better time complexity will be
4119 achieved when the printing code is completely rewritten.)
4121 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4123 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4124 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4125 it gets done whether or not the cache variable has a value.
4127 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4129 Distinguish #f and ().
4130 * __scm.h: #undef SICP.
4131 * pairs.h (SCM_EOL): Delete this definition, equating it with
4133 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4134 the value it used to have. Doc fixes, too.
4136 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4138 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4139 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4140 Lord's implementation of structs, allowing for tail arrays as
4141 described in the manual. Also fixed some bugs. (Both the interface
4142 and the implementation should be improved.)
4144 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4146 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4147 People who whish to see the source can do `(print-enable 'source)'.
4148 Removed #ifdef DEBUG_EXTENSIONS.
4150 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4152 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4153 integer (assuming for now accepting an integer is a good thing).
4155 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4156 %S will be used instead for write'ing arguments.
4158 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4159 asserts. fix a few other asserts.
4160 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4161 scm_uniform_vector_ref, scm_array_set_x,
4162 scm_dimensions_to_unform_array): change args in
4163 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4164 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4165 scm_substring_fill_x): likewise.
4166 gsubr.c (scm_gsubr_apply): likewise.
4167 eval.c (SCM_APPLY): likewise.
4169 * eval.c (4 places): replace scm_everr with lgh_error or
4172 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4173 scm_memory_error): new procedures.
4174 scm_everr: deleted. can use scm_wta, dropping first two args.
4175 scm_error: convert NULL subr to SCM_BOOL_F.
4177 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4180 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4183 * error.c, error.h: new error keys: scm_arg_type_key,
4184 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4186 scm_wta: reimplement using lgh_error instead of scm_everr.
4188 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4190 * gdbint.c: scm_lread now has one more argument.
4192 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4193 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4194 loading source from non-file ports, which, e. g., happens when
4195 using the Emacs interface).
4197 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4200 * read.c: Added code for recording of positions of source code
4201 expressions; New functions: recsexpr, scm_lreadrecparen;
4202 _scm_make_srcprops --> scm_make_srcprops
4203 (scm_flush_ws): Removed updating of positions counters. This work
4204 is already done by scm_gen_getc
4206 * read.h: Added prototype for scm_lreadrecparen
4208 * print.c: Added #include "alist.h"
4210 * eval.c: Added #include "hash.h"
4212 * eq.c: Added #include "ramap.h"
4214 * options.c: Documentation fixes.
4216 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
4217 (scm_init_srcprop): Adjusted size of initial source-whash. Name
4218 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
4219 --> scm_make_srcprops
4221 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
4222 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
4223 function calls in the definition of the whash access macros.
4225 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
4227 * init.c (scm_boot_guile): Add level of indirection to
4228 scm_boot_guile_1() to ensure that stack base pointer is properly
4229 initialized. There was no guarantee that variable i was the
4230 highest/lowest variable on stack (i.e. the call frame of
4231 scm_boot_guile was not completely protected from gc).
4233 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
4235 * ports.h (scm_port_table): put back file_name, it will be used to
4236 support debugging. Undo related changes in fports.c, ioext.c,
4239 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4241 * ports.h (scm_port_table): remove file_name member for now, it seems
4243 * fports.c (scm_open_file): don't set file_name in PTAB.
4244 (prinfport): don't use file_name in PTAB.
4245 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
4246 * ports.c (scm_add_to_port_table): don't intialize file_name.
4247 (scm_port_file_name): remove for now.
4248 * gc.c (scm_gc_mark): don't mark PTAB file_name.
4250 * fports.h (scm_mkfile): prototype deleted.
4251 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
4253 * debug.c, unif.c: use scm_out_of_range instead of
4254 wta for range errors (ASSERT still needs work).
4256 * error.c, error.h (scm_out_of_range): new procedure.
4258 * error.c, error.h (scm_out_of_range_key): new key.
4260 * posix.c (scm_sync): #else was missing.
4262 * error.c, error.h: append _key to names scm_num_overflow and
4265 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
4266 of consing an empty list.
4267 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
4268 of macros, saves code and string space.
4269 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
4270 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
4271 lower case. Rename scm_syserror_m to scm_syserror_msg.
4272 error.h: prototypes for new procedures.
4274 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
4276 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
4278 * error.c, error.h: setup scm_num_overflow key.
4280 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
4281 Remove definition of SCM_OVSCM_FLOW.
4283 * fports.c (scm_open_file): use SCM_SYSERROR_M.
4285 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
4286 explicit message and args.
4288 * error.c, error.h, __scm.h: change system_error_sym to
4291 * error.c (system_error_sym): remove leading %% from the Scheme name
4294 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
4296 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4298 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
4299 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
4300 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
4301 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
4302 renamed. (These were introduced by unsupervised name
4305 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4307 * print.c: Added code for detection of circular references during
4308 printing. (init_ref_stack, grow_ref_stack): New functions. Added
4309 a hook for printing of closures (accessible via print options).
4310 This leads to a split of calls to scm_iprin1 into two classes:
4311 elementary print operations (e. g. the code which prints a smob)
4312 still use scm_iprin1 while top level calls (like scm_display) use
4313 scm_prin1. scm_prin1 begins by clearing the data structure used
4314 to record reference information.
4316 * print.h: Added declarations of scm_prin1 and scm_prlist.
4318 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
4320 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
4322 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
4324 * error.c (err_head): scm_iprin1 --> scm_prin1
4326 * debug.c: Adjusted header comment.
4330 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4332 * strerror.c: Doc fix.
4334 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4336 * gdbint.c (gdb_read): Now possible to run during GC.
4337 (unmark_port, remark_port): New functions.
4339 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
4341 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
4342 of allocating a new string object. Also, increase size by
4343 the factor 2 instead of 1.5.
4345 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
4347 * __scm.h (SCM_P): Corrected to run under traditional C.
4349 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
4352 * async.c: Calls to scm_sysintern corrected.
4354 * async.h (scm_async_clock): Redundant declaration removed.
4356 * continuations.c (scm_dynthrow): Redundant declaration removed.
4358 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
4359 Definition typos corrected.
4361 * debug.h: Missing declarations of functions in debug.c added
4364 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
4365 Missing declarations to functions in eval.c added.
4367 * filesys.c: Possibly uninitialized variable rv.
4369 * gc.h (scm_object_addr, scm_unhash_name): Missing
4370 declarations of functions defined in gc.c added.
4372 * genio.c: Possible typos str_data -> wstr_data. ???
4374 * genio.c: Possibly unintended shadowing of local variable
4375 `int c' (gotos out of scope of inner `c'). ???
4377 * init.c: Uninitialized `SCM last' may be used.
4379 * ioext.h: (scm_sys_isatty_p): Typo.
4381 * list.h (scm_list_head): Missing prototype for function in
4384 * numbers.c (scm_two_doubles): Changed from extern to static
4385 (is used only within numbers.c).
4387 * numbers.h: Repeated declarations removed.
4389 * ports.h (scm_close_all_ports_except): Declaration for the
4390 function defined in ports.c added.
4392 * posix.h: Missing declarations added.
4394 * procs.h (scm_make_subr_opt): Missing declaration added.
4396 * socket.h (scm_sys_gethost): Missing declaration added.
4398 * socket.h: Redundant declarations removed (they are in fdsocket.h).
4400 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
4401 Missing declarations added.
4403 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
4405 * struct.c: Uninitialized variable `SCM answer' may be used.
4407 * unif.c (l2ra): Declaration prototype.
4409 * unif.c (scm_array_equal_p): Dummy definition removed (it is
4410 defined in ramap.c).
4412 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
4413 Redundant declarations removed (they are in ramap.h).
4415 * variable.h (scm_make_udvariable,
4416 scm_make_undefined_variable): Declaration corrected to
4417 correspond variable.c.
4419 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
4420 Missing declarations added.
4422 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
4424 * Makefile.in (distclean): Don't forget to delete fd.h.
4426 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4428 * fd.h.in, tags.h: Trivial cleanups.
4430 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
4431 marksweep.h just declared functions from gc.c.
4432 * gc.h, libguile.h: Don't #include "marksweep.h".
4433 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4434 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
4435 dependencies updated.
4437 * libguile.h: Don't #include "files.h"; it's been deleted.
4439 * files.c (scm_sys_delete_file): Moved to filesys.c.
4440 File is now empty; deleted.
4442 * filesys.c: scm_sys_delete_file is now here. Remove
4443 #if's; they seem to rely on remnants of an old portability
4444 regimen. If the problems come up again, solve them properly,
4445 using autoconf. Specifically: Don't test M_SYSV, and #define
4446 remove to be unlink if it's #defined; don't use remove just
4447 because HAVE_STDC_HEADERS is #defined.
4448 * filesys.h: Add declarations for scm_sys_delete_file.
4449 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4450 files.o, files.h, files.c, and files.x.
4451 * init.c: Don't #include "files.h", and don't call scm_init_files.
4453 Use SCM_P instead of PROTO; the latter intrudes on the user's
4455 * params.h: Deleted; definition of SCM_P moved to...
4456 * __scm.h: ... here, where it replaces PROTO macro.
4457 * libguile.h, smob.h: Don't #include "params.h".
4458 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
4459 smob.h: Fix prototypes accordingly.
4460 * Makefile.in: Update dependencies.
4461 (inner_h_files): Remove params.h.
4463 * gc.c: #include "gc.h"; every module should include its header,
4464 to let the compiler cross-check the declarations against the
4467 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
4468 simpos.h: #include "libguile/__scm.h".
4470 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
4472 * init.c: Don't forget to #include smob.h and init.h.
4473 * Makefile.in: Dependencies updated.
4475 * smob.h: Use PROTO instead of #if __STDC__.
4477 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
4479 * __scm.h: Doc fixes.
4481 * __scm.h, libguile.h: Use "quotes" in the #includes, not
4482 <angles>; this allows `make depends' to work properly.
4484 * libguile.h: #include smob.h and pairs.h before the others; they
4485 define typedefs used by other headers.
4487 C files should #include only the header files they need, not
4488 libguile.h (which #includes all the header files); the pointless
4489 recompilation was wasting my time.
4490 * Makefile.in (all .o dependency lists): Regenerated.
4491 * libguile.h: Don't try to get a definition for size_t here...
4492 * __scm.h: Do it here.
4493 * _scm.h: Since this is the internal libguile header, put things
4494 here that all (or a majority) of the libguile files will want.
4495 Don't #include <libguile.h> here; that generates dependencies on
4496 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
4497 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
4498 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

4595 * weaks.c: Get "weaks.h".
4597 * stackchk.h: #include "libguile/debug.h",
4599 * print.h, read.h: #include "options.h", since everyone who uses
4600 either of these files will need that.
4602 * smob.h: #include "ports.h", "genio.h", and "print.h", since
4603 anyone who uses this file will need them to define the smob
4604 printing functions. Also, get markers.h, since people will need
4605 to #define the mark functions.
4607 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
4608 * ports.h: ... to here.
4610 * ports.h (scm_port_table_size): Explicitly give type as 'int';
4611 don't rely on archaic C default type rules.
4613 * fports.h: #include "libguile/ports.h", since you need that in
4614 order to parse this.
4616 * genio.h: #include "libguile/print.h", because you need that to
4617 parse this; don't bother #including "ports.h", since print.h gets
4620 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
4622 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
4623 this; it's now a reference to an element of *scm_root.
4625 * debug.h: Don't #include "options.h"; the compiler won't be able
4626 to find that once the headers are installed; instead, #include
4627 "libguile/options.h".
4628 * gc.h: Same, with marksweep.h.
4629 * mbstrings.h: Same, with symbols.h.
4630 * scmhob.h: Same, with _scm.h.
4631 * smob.h: Same, with params.h.
4633 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
4634 C files; there's no need for this, and it forces recompilations
4637 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
4639 * error.c (scm_error): declare scm_error_callback.
4641 * error.h: prototype for scm_error_callback.
4643 * __scm.h: define lgh_error.
4644 (SCM_SYSERROR): redefine using lgh_error.
4646 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
4648 * error.c (scm_error): new procedure.
4650 * error.h: prototype for scm_error.
4652 * Makefile.in (install): install scmconfig.h from the current
4653 directory, not $(srcdir).
4655 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
4657 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
4658 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
4659 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
4660 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,

4665 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
4666 vports.h, weaks.h: #include "libguile/__scm.h", not
4667 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
4668 dependencies are within libguile properly.
4670 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
4672 * Makefile.in (.c.x): Simplify; there's no need to run this rule
4673 when scmconfig.h doesn't exist.
4675 * load.c (scm_sys_try_load): Correct spelling.
4677 * feature.c (scm_loc_features): Make this static.
4679 * Makefile.in (libpath.h): Omit trailing slash from path. We
4680 shouldn't require it of users, so why put it here?
4682 Move code to initialize and search %load-path from ice-9 to C
4683 code, so we can use the load-path to find the ice-9 boot code;
4684 this makes it easier to run Guile without installing it. See
4685 corresponding changes in guile/Makefile.in.
4686 * feature.c: Move stuff concerned with the load path to load.c.
4687 (scm_compiled_library_path): Deleted.
4688 Don't #include libpath.h here.
4689 * feature.h: Don't mention scm_compiled_library_path.
4690 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
4691 <sys/stat.h>, and <unistd.h> (if present).
4692 (R_OK): #define if the system hasn't deigned to.
4693 (scm_loc_load_path): New variable.
4694 (scm_init_load_path, scm_sys_search_load_path,
4695 scm_sys_try_load_path): New functions.
4696 (scm_init_load): Initialize scm_loc_load_path to point to the
4697 value cell of the Scheme %load-path variable.
4698 * load.h: Add declarations for scm_sys_search_load_path,
4699 scm_sys_try_load_path.
4700 * init.c: Call scm_init_load_path.
4701 * Makefile.in (feature.o, load.o): Dependencies updated.
4703 * load.c, load.h: Rewrite using PROTO macro.
4705 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4707 * gc.c (scm_cellp): New function: C predicate to determine if an
4708 SCM value can be regarded as a pointer to a cell on the heap.
4710 * gc.h: Added declaration of scm_cellp.
4712 * gdb_interface.h: New file: The GDB interface header from the GDB
4715 * gdbint.c: New file: GDB interface.
4717 * gdbint.h: New file: GDB interface.
4719 * libguile.h: Added #include <libguile/gdbint.h>.
4721 * init.c (scm_boot_guile): Added scm_init_gdbint.
4723 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
4724 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
4725 found if object files and source are kept separate).
4727 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
4729 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
4731 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
4733 * configure.in: Don't substitute the values of TCL_SRC_DIR and
4734 TK_SRC_DIR; they're not relevant any more.
4736 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
4737 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
4739 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
4741 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
4742 search path, so we can find the <libguile/MUMBLE.h> headers.
4744 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
4746 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
4747 implicit in the .c.o rule.
4748 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
4751 Put the library path in a header file, instead of passing it on
4752 the command line in every compilation.
4753 * Makefile.in (libpath.h): New target.
4754 (feature.o): Depend on libpath.h.
4755 (clean): Delete libpath.h.
4756 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
4757 * feature.c: ... #include "libpath.h" here.
4758 * .cvsignore: Ignore libpath.h.
4760 Don't install the unwashed masses of Guile header files in the
4761 main #include path; put most of them in a subdirectory called
4762 'libguile'. This avoids naming conflicts between Guile header
4763 files and system header files (of which there were a few).
4764 * Makefile.in (pkgincludedir): Deleted.
4765 (innerincludedir): New variable; this and $(includedir) are enough.
4766 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
4767 (installed_h_files): Divide this up. Now this variable lists
4768 those header files which should go into $(includedir) (i.e. appear
4769 directly in the #include path), and ...
4770 (inner_h_files): ... this new variable says which files appear in
4771 a subdirectory, and are referred to as <libguile/mumble.h>.
4772 (h_files): List them both.
4773 (install): Create innerincludedir, not pkgincludedir. Put
4774 the installed_h_files and inner_h_files in their proper places.
4775 (uninstall): Corresponding changes.
4776 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
4777 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,

4784 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
4785 vports.h, weaks.h: Find __scm.h in its new location.
4786 * __scm.h: Find scmconfig.h and tags.h in their new locations
4787 (they're both "inner" files).
4789 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
4791 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
4793 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4795 * posix.c: Doc fixes.
4797 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
4799 * socket.c: Don't include a prototype for inet_aton; just use a
4800 K&R style declaration, to avoid warnings but minimize the chance
4801 of conflicts with the system.
4803 On NextStep, <utime.h> doesn't define struct utime, unless we
4804 #define _POSIX_SOURCE before #including it.
4805 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
4806 * acconfig.h: New comment text for above CPP symbol.
4807 * configure.in: Call it.
4808 * posix.c: #define _POSIX_SOURCE if it seems necessary.
4810 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
4812 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
4813 testing for __EMX__.
4815 * posix.c: #include <libc.h>, if it exists.
4817 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
4818 don't even know if the latter exists.
4820 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
4821 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
4822 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
4824 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
4826 (scm_init_posix): Use them when initializing the Scheme constants
4829 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4831 * Makefile.in (libdir, includedir, bindir): Use the
4832 autoconf-supplied values, instead of deriving them ourselves.
4833 (pkgincludedir, datadir, pkgdatadir): New variables.
4834 (install, uninstall): Put the header files in a special
4835 subdirectory, not in the main search path.
4837 * Makefile.in (ALL_CFLAGS): Provide the proper value for
4838 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
4840 * Makefile.in (IMPLPATH): Deleted; never used.
4842 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
4843 on the Tcl/Tk source any more.
4844 (INCLUDE_CFLAGS): Remove references to the above.
4846 * Makefile.in (version.o): Corrected dependencies.
4848 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
4850 * libguile.h: #include "version.h"
4852 * init.c (scm_boot_guile): Call scm_init_version.
4853 * gscm.c (gscm_run_scm): Call scm_init_version.
4855 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
4856 GUILE_VERSION): AC_DEFINE these.
4857 (acconfig.h): #undef the above symbols.
4859 * Makefile.in (libobjs): Add version.o.
4860 (installed_h_files): Add version.h.
4861 (c_files): Add version.c.
4862 (gen_c_files): Add version.x.
4863 (version.o): New rule.
4864 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
4865 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

4873 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
4874 weaks.o): Add version.h to dependency lists.
4875 (markers.o): Remove duplicate rule.
4877 * version.h: New file.
4879 * version.c: New file.
4881 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4883 * symbols.c (scm_strhash): scm_downcase is now a function, not an
4884 array; use it appropriately. Since GCC is quite happy to
4885 subscript functions, it never warned us about this; we should use
4886 -Wpointer-arith in the future. I guess we never tested
4889 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
4891 * socket.c: Doc and copyright fixes.
4893 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4895 * debug.c: Fixed and improved gdb support.
4897 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4899 * socket.c: Added declaration of inet_aton to avoid compiler
4900 warning. (Hope this solution is correct.)
4902 * stime.c: Added declaration of ftime. (This is missing in
4905 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
4907 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
4909 * Makefile.in (c_files): add strerror.c.
4911 * strerror.c: new file from Emacs' sysdep.c.
4912 maybe configure should also check for sys_errlist.
4914 * configure.in (AC_REPLACE_FUNCS): add strerror.
4916 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4918 * debug.c (scm_init_debug): Added initialization for
4919 scm_evaluator_traps.
4921 * debug.h, debug.c: Various name changes.
4922 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
4923 "debug-options-interface". See commentary in options.c.
4925 * options.h, options.c: Options now have documentation strings.
4926 Also added a long explanatory commentary.
4928 * eval.c, print.h, print.c, read.h, read.c: Modifications to
4931 * gscm.c, init.c, root.c, throw.c: Bug fixes:
4932 last_debug_info_frame is now updated in all cases.
4934 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
4937 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4939 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
4940 Added option STACK_CHECKING.
4942 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4944 * Makefile.in: Added {debug,options,srcprop}.{h,c}
4946 * __scm.h: Removed symbols for debugging support.
4948 * acconfig.h: Added symbols for debugging support.
4950 * configure.in: Added user option for debugging support.
4951 --enable-debug will include the debugging code into libguile.a.
4953 * continuations.c (scm_make_cont): Enlarged the #if 0 around
4954 scm_relocate_chunk_to_heap.
4956 * debug.c: New file: low-level debugging support. It also
4957 includes support for debugging with gdb. (The extensions to gdb
4958 are written by Per Bothner at Cygnus.)
4960 * debug.h: New file: low-level debugging support.
4962 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
4963 argument pairs. Extensive modifications to the debugging
4964 evaluator. Added "SECTION:" commentaries to clarify what happens
4965 when, during double compilation. Renamed EVALIMP --> EVALIM.
4966 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
4967 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
4968 the beginning of the file. New procedure: scm_unmemocopy.
4969 Added some global state variables needed by the debugging
4970 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
4971 check_entry, check_apply, check_exit, debug_options and
4972 evaluator_traps. New acro: undefine.
4974 * eval.h: Renamed EVAL --> XEVAL.
4976 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
4977 --> scm_make_weak_key_hash_table.
4979 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
4980 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
4982 * libguile.h: Conditionally include debug.h
4984 * objprop.c (scm_object_properties, scm_set_object_properties_x):
4985 scm_object_properties shouldn't return handle. `handle' now gets
4986 initialized in scm_set_object_properties_x. scm_object_properties
4987 doesn't any longer create an entry in scm_object_whash.
4989 * options.c: New file: handling of run time options.
4991 * options.h: New file: handling of run time options.
4993 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
4995 * print.c: New procedure: scm_print_options
4997 * print.h: Defines for print options.
4999 * read.c: New procedure: scm_read_options
5001 * read.h: Defines for reader options.
5003 * root.h: Added scm_source_whash among scm_sys_protects.
5005 * srcprop.c: New file: source properties.
5007 * srcprop.h: New file: source properties.
5009 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5010 (Bug found by A. Green.)
5012 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5014 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5016 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5018 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5020 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5021 and should be called by the final client.
5023 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5025 * gc.h: Use the PROTO macro when declaring functions.
5026 * gc.c: Use the PROTO macro when declaring static functions.
5027 Remove the CPP hair around function definitions.
5029 * gc.c (scm_init_storage): Initialize scm_asyncs.
5031 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5032 preprocessor symbol; "__scm.h" is where it might get #defined.
5033 * __scm.h: Similar: #include <scmconfig.h> before testing
5036 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5038 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5040 * init.c (scm_boot_guile): Add init_func argument; call
5041 (*init_func) instead of calling scm_appinit; it's ucky to
5042 hard-code names for the user's procedures.
5043 * init.h (scm_boot_guile): Adjust declaration.
5045 * __scm.h (PROTO): New macro, for declaring functions with
5048 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5049 eliminate all the __STDC__ conditionals.
5050 (scm_boot_guile): Add declaration.
5051 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5052 Remove __STDC__ conditionals around function definitions; the
5053 declarations in init.h will provide the same information, more
5056 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5057 complain about it in the error message; the error message is
5058 adequate without that note, and there's nothing the user can do
5061 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5063 * Makefile.in (ancillary): Drop def.sed.
5065 * posix.c (scm_init_posix): Use numeric values, rather than
5066 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5067 F_OK. The symbols aren't available on some systems, and I'm
5068 pretty sure their values are fixed by common widespread practice.
5069 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5071 More functions unavailable on some systems.
5072 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5073 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5075 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5076 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5077 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5078 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5079 stub that signals an error as the #else.
5081 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
5083 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
5085 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
5087 * unif.c: include ramap.h.
5089 * read.c (endif): case_insensative_p renamed case_insensitive_p.
5091 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
5093 * ports.c: include sys/ioctl.h.
5095 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
5097 * configure.in: check for sys/ioctl.h.
5099 * ports.c: include <malloc.h> not "malloc.h".
5101 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5103 * fports.c: remove ttyname and tmpnam declarations.
5105 * posix.c: fewer ttyname declarations.
5107 * fports.c: include <string.h> not "string.h".
5109 * init.c, ioext.c: include string.h and unistd.h.
5111 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5113 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
5114 genio.c, simpos.c, vports.c: include string.h.
5116 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
5118 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
5120 (scm_addr_buffer_size): change type from scm_sizet to int.
5121 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
5122 from scm_sizet to int.
5124 * error.c: include unistd.h.
5126 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
5129 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
5131 * __scm.hd, def.sed: deleted.
5133 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
5135 Changes for NeXT, suggested by Robert Brown.
5136 * configure.in: Call AC_TYPE_MODE_T.
5137 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
5138 NeXT. Put header file list in alphabetical order.
5139 * configure, scmconfig.h.in: Regenerated.
5140 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
5142 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
5145 * acconfig.h: New file, providing documentation for the CPP
5146 symbols defined in configure.in
5147 * acconfig-1.5.h: Removed; superceded by the above.
5149 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
5151 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
5153 * fports.c (scm_open_file): don't return #f, throw error.
5155 * ioext.c (fileno): renamed from %fileno.
5156 (soft-fileno): deleted.
5158 * ports.c (scm_port_revealed): don't need to check for -1 from
5160 (scm_set_port_revealed_x): return unspecified, not #f.
5162 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
5164 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
5166 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
5168 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
5170 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5172 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5173 This is necessary on Ultrix, and doesn't hurt portability.
5175 * Makefile.in (dist-dir): New target, implementing a new dist system.
5176 (installed_h_files): Put in alphabetical order.
5177 Remove duplicate entries for markers.h and unif.h.
5178 (c_files): Remove duplicate entries for markers.c.
5179 (ancillary): Renamed from anillery; all uses changed. Remove
5180 PLUGIN; it's a directory, and needs special treatment in dist-dir.
5181 Remove all the ../doc/* files; doc/Makefile.in handles that.
5183 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5185 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5186 every if must have an else, or else the whole command has a
5187 non-zero exit code whenever the if's condition is false.
5189 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
5191 * posix.c: include string.h.
5193 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
5195 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
5198 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
5199 Remove leading % from scheme names.
5200 Do not return error values, call SCM_SYSERROR or similar.
5202 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
5204 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
5206 * struct.c (scm_init_struct): new file.
5208 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
5210 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
5211 (scm_list_head): added list-head for rapidly chopping argument
5212 lists off of longer lists (and similar).
5214 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
5216 * objprop.c (scm_object_property): assq the cdr of the whash
5217 handle for obj, not the handle itself.
5219 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
5221 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
5222 weak hash tables last of all marking to avoid an obscure gc bug.
5223 WARNING: circular lists stored in a weak hash table will hose us.
5225 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
5227 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
5228 new functions similar to scm_substring_move_left_x and
5229 scm_substring_move_right_x.
5231 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
5233 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
5236 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
5238 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
5240 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
5242 * strports.c (scm_strprint_obj): convenience function. C for
5243 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
5245 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
5246 removed to a separate library
5248 * init.c (scm_boot_guile): copied from guile-tcl.c.
5249 Initialization specific to tcl interpreters removed.
5251 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
5253 * ports.c (scm_ports_prehistory): size malloced here doesn't
5254 matter so long as it is non-0 (got rid of "* 4").
5256 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
5258 * gscm.h: gscm_mkarray eliminated (presumably was not being used
5259 since its definition was bogus).
5261 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
5263 * mallocs.[ch]: back again (for rx at least).
5265 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
5267 * ports.c: removed functions relating to the mapping between ports
5268 and descriptors. (That stuff is unix-specific and should be collected
5269 in a separate library).
5271 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
5272 (Tom Mckay@avanticorp.com)
5274 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
5276 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
5277 handled correctly (SCM_FREEP was applied to them) -- test for
5278 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
5279 being overwritten with #f. (brown@grettir.bibliotech.com)
5281 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
5283 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
5284 for a specific symbol or for all symbols.
5286 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>

5446 initialization to fix a race condition.
5448 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
