1 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>
3 * script.c (scm_compile_shell_switches): Define
4 use-emacs-interface in the root module, so the repl code can see
5 it. See today's change to top-repl in ice-9/boot-9.scm.
7 * filesys.c (set_element, get_element): Make sure that `element'
8 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
9 Boekemeier and Jorgen "forcer" Schaefer.)
11 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
13 * chars.c (scm_charnames): In ASCII character name table, make
14 newlines print as #\newline by default, not #\nl.
16 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
17 alphabetical order. Oh thrills. But it helps me know how far
18 along in the compilation I am.
19 * Makefile.in: Regenerated.
21 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
23 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
24 #bytes(...) to #y(...), and syntax for short vectors from
25 #short(...) to #h(...). This may seem nutty, but, like the other
26 uniform vectors, byte vectors and short vectors want to have the
27 same print and read syntax (and, more basic, want to have read
28 syntax!). Changing the read syntax to use multiple characters
29 after the hash sign breaks with the conventions used in R5RS and
30 the conventions used for the other uniform vectors. It also
31 introduces complexity in the current reader, both on the C and
32 Scheme levels. (The Right solution is probably to change the
33 syntax and prototypes for uniform vectors entirely.)
35 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
37 Don't use local_fgets on sockets; ftell doesn't work on sockets.
38 (Thanks to Jorgen "forcer" Schaefer.)
39 * ports.h (SCM_NOFTELL): New flag.
40 * fports.c (local_fgets): If it's set, use the generic fgets.
41 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
43 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
45 * script.c (scm_compile_shell_switches): Add handling of -q switch
46 (inhibit loading of user init file).
47 (scm_shell_usage): Add usage text for -q switch.
48 (scm_compile_shell_switches): Always load user init file first if
51 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
53 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
54 and is now broken under NetBSD. I can't fathom what it's trying
55 to do, so I've replaced it with something that I do understand,
56 which seems to work, and which isn't broken on NetBSD. "Progress?
57 You Decide." (Thanks to Perry Metzger.)
59 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
60 signed/unsigned comparison.
62 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
64 Warning fixes from Greg Harvey:
65 * unif.c (scm_array_set_x): initializer for pos
66 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
67 * struct.c (scm_struct_ref, scm_struct_set_x): Added
68 initializers for field_type, since EGCS so desparately wants to
70 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
71 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
72 when GUILE_DEBUG is defined.
73 * dynwind.h (scm_wind_chain): Same.
74 * ports.h (scm_pt_size, scm_pt_member): Same.
75 * print.h (scm_current_pstate): Same.
76 * procs.h (scm_make_cclo): Same.
78 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
80 Handle short and long long uniform arrays properly. (Thanks to
82 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
83 raeql_1): Add cases for scm_tc7_svect (short vectors) and
84 scm_tc7_llvect (long long vectors).
86 Change the way libguile and boot-9.scm are timestamped, to try to
87 get rid of these spurious mismatch warnings. Now both
88 libguile/versiondat.h and ice-9/version.scm are generated directly
89 by the configuration process, rather than having version.scm
90 generated directly, and libguile/versiondat.h generated by the
91 Makefile, which is generated by configure. It seems that
92 sometimes the Makefile would change, but versiondat.h depends on
93 Makefile.in, not Makefile, so it wouldn't get rebuilt.
94 * Makefile.am (versiondat.h): Target removed; this is generated
95 directly by the configure script now.
96 (BUILT_SOURCES): Remove versiondat.h.
97 * versiondat.h.in: New file, transformed by the configure script
99 * Makefile.in: Regenerated.
101 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
102 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
103 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
104 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
105 if we want to use them in a header file some day, we can. (Thanks
108 * stime.c (scm_get_internal_real_time): Do the arithmetic using
109 SCM numbers, so we won't have rollover problems; the range of a
110 signed long in milliseconds is about 25 days. (Thanks to Karl
113 Don't redefine sleep and usleep; fix this problem now.
114 * coop.c (sleep, usleep): Remove declarations; we don't use or
115 redefine these any more.
116 (scm_thread_usleep, scm_thread_sleep): New functions which do the
117 job of usleep and sleep in a thread-friendly way. We can use
118 these in the rest of Guile. Define versions for systems both with
120 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
121 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
122 we're just using it, not redefining it, we can use a K&R style
124 (sleep): Declare this, too, if the system hasn't.
125 (scm_sleep, scm_usleep): Use scm_thread_sleep and
126 scm_uthread_sleep if they're available; otherwise, just call the
128 * scmconfig.h.in: Regenerated.
130 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
132 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
134 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
136 * threads.c: Doc fix.
138 The argument type of usleep varies from system to system,
139 as does the return type. We really shouldn't be redefining usleep
140 at all, but I don't have time to clean that up before the 1.3.
141 release. It's on the schedule for afterwards. (Thanks to Julian
143 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
145 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
146 * scmconfig.h: Regenerated.
148 * simpos.c (scm_software_type): Procedure deleted. This isn't the
149 right way to handle system variation. Autoconf's approach is the
151 * simpos.h (scm_software_type): Declaration deleted.
153 * script.c (scm_find_executable): Don't test if unix is #defined
154 here; first, NetBSD doesn't #define it, and second, it's the wrong
155 way to go about these things. (Thanks to Perry Metzger.)
156 (dld_find_executable): Delete this MSDOS support code. This isn't
157 the way we want to support this; it needs to be rethunk at a
160 * genio.c (scm_do_read_line): Don't just politely check that the
161 line was either non-empty or EOF. Abort if it's empty and not
164 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
166 * scmconfig.h.in: Regenerated.
168 * libguile.h: Don't omit the dynamic linking functions. (Thanks
171 * genio.c (scm_do_read_line): Count lines correctly when the file
172 doesn't end in a newline.
174 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
176 * genio.c (scm_do_read_line): Maintain the line count correctly.
177 (Thanks to Harvey J. Stein and Greg Harvey.)
179 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
182 * numbers.c (big2str): Protect t from garbage collection until
183 we're done. (Thanks to Gary Houston.)
185 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
187 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
189 * Makefile.in: Regenerated.
191 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
192 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
195 Do magic to mix reads and writes on stdio FILE-based ports.
196 (Thanks to Christian Lynbech.)
197 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
199 (pre_read, pre_write): New functions.
200 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
201 local_fputs): Call them.
202 (local_fflush): Mark the port as ready for reading and writing.
203 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
204 flags on new port objects. This might not be accurate --- who
205 knows what state the FILE * is in when we get it --- but it won't
206 do extraneous calls to fflush or fseek, so it's no worse than the
207 behavior before this change.
208 * ports.h: Add comment.
210 Centralize the creation of port objects based on stdio FILE * in
211 fports.c; don't just throw them together anywhere.
212 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
213 what the rest of Guile wants. Don't set the revealed count;
214 that's only appropriate for stdin, stdout, stderr.
215 (scm_standard_stream_to_port): This function does set the revealed
217 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
218 not scm_stdio_to_port.
219 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
220 * fports.c (scm_open_file): Same.
221 * posix.c (scm_pipe): Same.
222 * socket.c (scm_sock_fd_to_port): Same.
223 * ioext.c (scm_fdopen): Same.
224 (scm_freopen): Moved from here to...
225 * fports.c (scm_freopen): ... here. This is really something that
226 munges the internals of an fport, so it should go here.
227 * fports.h (scm_stdio_to_port): Adjust prototype.
228 (scm_standard_stream_to_port, scm_freopen): New protoypes.
229 * ioext.h (scm_freopen): Prototype removed.
231 * filesys.c (set_element, get_element): This can work on both pipe
232 and file ports, so use SCM_FPORTP to typecheck, instead of testing
235 * scmconfig.h.in: Regenerated.
237 Change the definition of the functions in scm_ptobfuns so that
238 they get passed the port object, not the port's stream.
239 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
240 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
241 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
242 Pass the port itself to the scm_ptobs function.
243 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
244 scm_generic_fgets): Same.
245 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
246 getc_void_port, fgets_void_port, close_void_port): Just change the
247 argument names; these functions don't really do anything.
248 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
249 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
250 port as an argument, and use SCM_STREAM to get the stdio FILE *.
251 Also, use prototyped definitions, and get rid of the extra
253 (scm_fptob, scm_pipob): We don't need casts here any more.
254 * strports.c (prinstpt): Use prototype declarations.
255 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
256 and use SCM_STREAM to get the string info. Also, use prototyped
257 definitions, and get rid of the extra declarations.
258 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
261 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
262 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
264 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
265 scm_fgets, for consistency.
266 (scm_fptop, scm_pipob): References updated.
268 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
270 Include the source location in error messages for scripts.
271 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
272 stack is still there when we catch the error.
273 * throw.c (handler_message): If we are handling an error with a
274 message, then put together the proper arguments and call
275 scm_display_error, instead of scm_display_error_message. That
276 displays source location, if it can find it.
278 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
280 * gc.c (scm_unprotect_object): Change this so that calls to
281 scm_protect_object and scm_unprotect_object nest properly.
282 (scm_protect_object): Doc fixes.
284 * strings.c (scm_string_set_x): Require the argument to be a
285 writable string, not a substring or a symbol.
286 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
287 (Thanks to John Redford and Charbel Jacquin.)
289 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
291 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
293 * eval.c (safe_setjmp): Remove this misunderstanding.
294 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
297 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
299 * libguile.h: Mark these as C declarations, for compilation by C++
302 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
303 __cplusplus clause. I seriously doubt this ever worked the way
304 the author seems to have intended.
306 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
308 Utterly needless cleanups to hopelessly messy code.
309 * ports.c: Doc fixes.
310 (scm_fflush): Moved to ...
311 * genio.c (scm_fflush): ... here, amongst all the other port
312 method invocation functions.
313 * genio.h, ports.h: The prototype moves too.
315 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
317 * backtrace.c (display_error_body): The current frame does not
318 always have a parent frame; consider a function called directly
319 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
322 * alloca.c (alloca): Undo yesterday's changes, and simply call
323 malloc directly for storage, and abort if we don't get what we
324 want. The situation is much simpler --- just call malloc. Emacs
325 has bizarre/evil requirements (signal handlers might malloc unless
326 you set this global flag, so you have to set the flag around all
327 calls to malloc) which we are certainly not going to conform to,
328 so we can do the simple and obvious thing.
330 * coop.c (coop_condition_variable_wait): Make this function
331 static. It's only useful internally --- you should never just
332 wait on a condition variable.
333 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
335 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
337 * unif.c (scm_array_set_x): Accept any kind of number as an
338 element for a uniform vector of doubles. This is more consistent
339 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
341 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
342 works; I can't conveniently test it myself. (Thanks to Dvid
343 Tillman for the bug report.)
347 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
348 from here, not from scm_compile_shell_switches (which is a pretty
349 dumb place to do it).
350 (scm_load_startup_files): New function.
351 (scm_ice_9_already_loaded): Variable moved to here from script.c.
352 * script.c (scm_compile_shell_switches): Don't load the startup
354 (scm_ice_9_already_loaded): Variable moved.
355 * init.c (scm_load_startup_files): Prototype for new function.
356 * gh_init.c (gh_enter): Doc fix.
358 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
360 Some anti-warning changes from Greg Harvey.
361 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
362 warnings when it doesn't understand our NORETURN declarations in
364 * posix.c (scm_mknod): Similar.
366 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
368 * posix.c (scm_getpwuid): If we can't find an entry, return our
369 own message, instead of using scm_syserror --- the getpwMUMBLE
370 functions don't set `errno' to anything interesting.
372 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
374 Get rid of warnings from the cooperative threading system.
375 * threads.h (scm_single_thread_p, scm_yield,
376 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
377 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
378 scm_wait_condition_variable, scm_signal_condition_variable): Add
379 prototypes for these Scheme-visible functions.
380 * coop-defs.h (coop_next_runnable_thread,
381 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
382 Prototypes for these here, even though they're from iselect.c.
383 (coop_condition_variable_wait, coop_join): Add prototypes.
384 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
385 scm_threads_free_condvar): Make these smob functions static.
386 * coop-threads.h (coop_init): Give this a real prototype.
387 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
388 (coop_next_runnable_thread): No need to provide prototype; it's in
391 * scmconfig.h.in: .detarenegeR
393 * iselect.c, threads.c: Doc fixes.
395 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
397 * Makefile.in: Regenerated with a patched automake, to get
398 dependency generation right when using EGCS.
400 * inet_aton.c (inet_aton): Add prototype, to remove compiler
401 warning. (Thanks to Robert Pluim.)
403 * inet_aton.c (inet_aton): Reassure the compiler that the
404 arguments to the <ctype.h> macros are all unsigned characters, not
407 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
409 Getting rid of more warnings...
410 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
411 today's change to ../configure.in.
412 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
413 * scmconfig.h.in: Regenertaded.de.,.__
414 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
415 (scm_localtime, scm_mktime): Use a const char * to manipulate the
418 * readline.c: Doc fix.
419 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
420 * readline.h (scm_filename_completion_function): Add prototype.
421 (scm_init_readline): Make this into a prototype.
423 * readline.c (scm_filename_completion_function): Use SCM_PROC to
424 declare this, instead of calling scm_make_subr manually.
426 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
428 * readline.h (scm_init_readline): Add prototype for this.
429 (scm_init_readline): Make this a real prototype.
431 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
433 Warning fixes from Maciej Stachowiak:
434 * backtrace.h (scm_display_application, scm_backtrace): Add
436 * debug.c (scm_m_start_stack): Make this function static.
437 * fluids.h (scm_fluid_p): Add prototype.
438 * procprop.c (scm_i_procedure_arity): Make this function static.
439 * regex-posix.c (scm_regexp_error_msg): Make this function static.
440 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
441 * root.h (scm_dynamic_root): Add external prototype.
442 * scmsigs.h (scm_usleep): Add external prototype.
443 * script.h (scm_init_script): Use prototype, not K&R decl.
444 * stacks.h (scm_stack_id): Add external prototype.
445 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
447 1998-09-30 Mark Galassi <rosalia@cygnus.com>
449 * gh.h: took out the definitions of vset and vref, since they are
450 replaced by the proper vector routines that correspond to the R4RS
453 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
455 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
456 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
457 third argument, a C expression that should result in a SCM value,
458 which is used to initialize the variable. Reimplemented
459 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
462 * version.h (scm_libguile_config_stamp): Add prototype.
463 (From Maciej Stachowiak.)
465 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
467 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
468 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
470 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
472 * print.c (scm_iprin1): Rather than having one i, and using it in
473 several places, declare a fresh i local to each block where it is
474 used, and give it a signedness appropriate to its use in each case.
477 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
480 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
481 signed/unsigned clashes.
483 * posix.h (scm_tmpnam): Added prototype.
485 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
486 scm_make_subclass_object): Add external prototypes.
488 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
489 comparison is okay here.
491 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
493 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
494 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
496 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
499 * load.c (swap_port): Make this function static.
501 * load.c (scm_search_path): Make max_path_len and max_ext_len
502 unsigned, since they're compared against string sizes.
504 * load.c (init_build_info): Make i unsigned.
506 * ioext.h (scm_read_line): Add prototype.
508 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
509 scm_hash_fn_remove_x): Make hash bucket index local variable k
510 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
511 accurately as possible.
513 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
514 comparisons, and range checking to make sure those casts are
517 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
518 signed/unsigned comparisons.
520 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
521 avoid signed/unsigned comparisons.
522 * smob.h (scm_numsmob): Change extern declaration to match.
524 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
525 avoid signed/unsigned comparisons.
526 * ports.h (scm_numptob): Change extern declaration to match.
527 (scm_current_load_port, scm_set_port_line_x,
528 scm_set_port_column_x): New prototypes.
530 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
531 test code, and it causes warnings.
533 * gh.h (gh_int2scmb, gh_uniform_vector_length,
534 gh_uniform_vector_ref): Added prototypes.
536 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
537 debugging support unconditionally. That's backtrace.c, stack.c,
538 debug.c, and srcprop.c.
539 (EXTRA_libguile_la_SOURCES): Omit those from here.
540 * Makefile.in: Regenerated.
542 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
544 * options.c (scm_options): Bugfix: Allow empty list of options!
546 * debug.c, debug.h (scm_single_step): Removed.
547 (scm_with_traps): New procedure. This procedure could easily be
548 written in Scheme but needs to be highly optimized.
550 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
552 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
553 Check SCM_TRAPS_P before trapping.
555 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
557 Changes to avoid signed/unsigned comparison warnings.
558 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
559 (scm_gc_sweep): Make n and j local to the blocks they're used in,
560 so they can have appropriate types for each application. Make i
561 signed. Use initializers in some spots. I'll probably pay for
563 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
564 (scm_must_realloc): Make nm unsigned.
565 (init_heap_seg): Make new_seg_index and n_new_objects signed.
566 (scm_init_storage): Use prototype-style definition, and make the
568 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
569 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
571 * filesys.c (scm_readlink): Make local vars rv and size ints, to
572 avoid signed/unsigned comparison warnings, and because the return
573 value of readlink may be -1. Don't bother casting the third
574 argument to readlink.
576 * filesys.c (scm_dirname, scm_basename): Move these to their own
577 page, at the end of the file.
578 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
580 * eval.h (scm_eval_options_interface): Add external prototype for this.
581 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
583 * eval.c (scm_lookupcar1): Make this static.
585 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
586 Make these prototype declarations, not K&R-style.
588 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
589 unsigned comparison warning.
591 * appinit.c: File removed. It had a single function in it, empty,
592 whose reason for existence is explained in no documentation or
593 comment. I think it's there as a default for some Tcl-style
594 initialization, but Tcl abandoned that approach a while ago.
595 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
596 (BUILT_SOURCES): Remove appinit.x.
597 * Makefile.in: Regenerated.
599 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
601 * Makefile.in: Regenerated using the last public version of
602 automake, not the hacked Cygnus version.
604 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
606 Remove Totoro kludge.
607 * Makefile.in, scmconfig.h.in: Regenerated.
608 * init.c, readline.c: Don't check if TOTORO is #defined.
610 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
612 * Makefile.am: Adjust for new thread configuration system.
613 (INCLUDES): Include the value of THREAD_CPPFLAGS.
614 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
616 (THREAD_LIBS): Definition deleted; automake will generate such
617 things automatically.
618 * Makefile.in: Regenerated.
620 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
622 Simplify smob and port marking; set the mark bit in the generic
623 marking code, and make marker routines only responsible for
624 turning up outgoing pointers.
625 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
626 before calling the marking function. Don't call the marking
627 function if it's zero.
628 * markers.c (scm_mark0): Just return #f. This function isn't
629 necessary at all now, but it's harmless to call it. We'll leave
630 it in so other folks' code doesn't croak at link time.
631 (scm_markcdr): Don't call SCM_SETGC8MARK.
632 * async.c (mark_async): Don't call SCM_SETGC8MARK.
633 * dynl.c (mark_dynl_obj): Same.
634 * root.c (mark_root): Same.
635 * srcprop.c (marksrcprops): Same.
636 * unif.c (markra): Same.
637 * variable.c (scm_markvar): Same.
638 * ports.c (scm_markstream): Same.
639 (void_port_ptob): Specify zero for our marking function.
640 * debug.c (debugobjsmob): Same.
641 * dynwind.c (guardsmob): Same.
642 * filesys.c (dir_smob): Same.
643 * fluids.c (fluid_smob): Same.
644 * fports.c (scm_fptob, scm_pipob): Same.
645 * mallocs.c (mallocsmob): Same.
646 * regex-posix.c (regex_t_smob): Same.
647 * smob.c (freecell, flob, bigob): Same.
648 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
649 * throw.c (jbsmob, lazy_catch_funs): Same.
651 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
653 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
654 scm_copy_tree on code in order not to let memoized code to leak
655 out. Thus, scm_copy_tree needs to copy vectors as well since
656 quasiquote can introduce evaluated code also inside vector
659 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
661 * eval.c (scm_copy_tree): Removed ability to copy vectors.
663 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
664 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
667 * unif.c: Say that ivect and uvect are of type signed and unsigned
668 long instead of int in commentary so that it correctly describes
671 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
673 * stime.c: Removed declaration of strptime. (It should be
674 declared by the system headers. If it turns out that some systems
675 don't, we'll handle that then.) (Thanks to Greg Troxel.)
677 * stime.h: Renamed TIMEH --> STIMEH
679 * backtrace.c (scm_display_error, scm_display_backtrace): In order
680 to increase portability, don't use structure assignment.
681 (Thanks to Nicolas Neuss.)
683 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
685 (finalize_fd_sets): Added empty statement after last case label.
686 (Thanks to Nicolas Neuss.)
688 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
691 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
693 * init.c, readline.c: OK, I won't have these readline.x bug
694 reports anymore. We've had them since April. The current reason
695 is a completely unintelligible failure of totoro.red-bean.com to
696 do the test for rl_getc_function in libreadline correctly. This
697 kludge overrides the test if we're on totoro so that the snapshot
698 generation process can work.
700 * readline.c: Define a strdup replacement if not existent on system.
702 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
704 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
705 This change makes scm_make_vector R5RS compatible. We cannot keep
706 the third argument since people want to be able to deduce the form
707 of the C function call only by looking at R5RS. (At the same time
708 we have removed some unnecessary complexity!)
710 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
711 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
712 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
713 argument in call to scm_make_vector.
715 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
717 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
718 This macro is useful in applications.
720 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
722 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
723 (scm_parse_path, scm_search_path): New Scheme level procedures.
725 * load.h (scm_internal_parse_path, scm_parse_path,
726 scm_search_path): Declared.
728 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
730 * filesys.c (dirname, basename): New procedures.
732 * init.c (scm_boot_guile_1): Removed condition around
735 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
736 new data type (guards) for representation of C level guards and
737 data on the wind chain.
738 (scm_internal_dynamic_wind): New function.
740 * dynwind.h: Declare scm_internal_dynamic_wind.
742 * root.h (scm_root_state): Added scm_cur_loadp.
744 * root.c (mark_root): Added comment about cur_loadp.
746 * load.c: #include "dynwind.h";
747 (scm_primitive_load): Use scm_inner_dynamic_wind to update
750 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
752 * ports.c (current-load-port): New procedure.
754 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
756 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
757 not a tty, return #f.
759 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
760 to Julian Satchell and Roland Kaufmann.)
762 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
763 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
765 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
767 * debug.h, debug.c (scm_start_stack): New function. Implements
768 the guts of old scm_m_start_stack.
770 * debug.c (scm_m_start_stack): Use scm_start_stack.
772 * init.c (scm_start_stack, scm_restart_stack): Renamed to
773 start_stack and restart_stack. (These have static scope.)
775 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
777 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
778 readline functions to come in release 2.3. (Thanks to Chet
780 (handle_errors): Use the above functions.
782 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
784 * readline.c: Improvements for readline support: Handle errors
785 better; Implement before-read-hook.
787 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
789 * init.c (scm_boot_guile_1), readline.c: Test for
790 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
791 assure that we have version >= 2.1.)
793 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
795 * readline.c (scm_readline): Defer interrupts while we're calling
798 * readline.c (scm_add_history): Bugfix: Do strdup before giving
799 away the string to add_history.
800 (completion_function): Do completion for readline. (Thanks to
802 (scm_filename_completion_function): New procedure: Filename
804 (current_input_getc): New function. Use this one instead of
805 standard getc from readline.
807 * throw.c, throw.h (scm_handle_by_throw): New function: This
808 handler throws errors to next handler on the dynwind chain.
810 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
812 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
815 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
817 * procprop.c (scm_i_procedure_arity): New function. Returns arity
819 (scm_procedure_properties): Modified to return arity together with
821 (scm_procedure_property): Added the read-only property `arity'.
822 (scm_set_procedure_property_x): It is an error to set the `arity'
825 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
826 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
828 * procprop.h (scm_sym_arity): New symbol.
830 * objects.c (scm_set_object_procedure_x): New procedure: Use this
831 to set the dispatch procedure of an operator or entity object.
833 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
834 Made procedure slots read-only.
836 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
837 scm_tcs_cons_gloc case in zero args switch; Fixed args
838 construction for operators in scm_tcs_cons_gloc case in two args
841 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
843 * fluids.c: Removed use of assert.h (in order to avoid
846 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
848 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
850 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
851 change makes the evaluator safer at the cost of evaluation speed.
852 It handles the case when the user has added a non-immediate
853 improper end of the application form, e.g., `(+ 0 . x)'.
854 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
855 minimize the extra cost as much as possible. The new code is
856 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
857 problem with structs planted directly in the code (e.g. by a
858 macro). This no longer causes segmentation fault. (Thanks to
861 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
862 arg `proc' in order to be able to throw errors; New argument
865 * Removed extra #include "debug.h"
867 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
869 * scmsigs.c: Declare usleep as returning void on some systems.
870 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
873 * coop.c (usleep): Return void on some systems.
875 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
877 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
879 * coop.c: Changed return type of usleep to int.
881 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
882 isn't found in the OS.
884 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
885 isn't enabled. (Thought that I had made this change ages ago...)
887 * iselect.c: Declare bzero if not defined by OS.
889 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
891 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
892 condition. (Thanks to John Tobey.)
894 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
895 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
898 * __scm.h: Start the long-term project of moving to POSIX threads.
899 Phase 1: Classification of all critical sections.
900 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
901 for A sections. (See comments in __scm.h for details.)
903 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
904 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
906 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
908 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
909 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
910 (libpath.h, versiondat.h): Replaced dependency on Makefile with
911 dependencies on $(srcdir)/Makefile.in
912 $(top_builddir)/config.status in order to avoid circularity.
914 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
915 from argc if argc was 0 initially.
917 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
918 in generation of libpath.h.
920 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
922 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
923 libguile from 2 to 3.
925 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
927 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
929 1998-04-13 Mikael Djurfeldt <mdj@kenneth>

937 stack size in machine words.
939 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
940 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
941 to Ole Myren Röhne.)
943 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
945 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
946 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
948 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
951 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
952 procedure apply: Copy argument lists before pushing them unto the
953 environment so that the environment won't get mutated due to
954 manipulation of procedure arguments. This should perhaps be
955 regarded as a temporary solution until someone finds a more
956 efficient one. (Thanks to Maciej Stachowiak.)
958 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
960 * script.c (scm_compile_shell_switches): Use "guile" as default
961 zero arg if argc is NULL.
963 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
965 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
966 is zero. (Thanks to Dirk Herrmann.)
968 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
970 * ports.c (scm_add_to_port_table): First line is now line 0
971 (was 1). (Interface changed according to suggestion by Per
974 * backtrace.c (display_header): Add 1 to line and column numbers
975 when presenting them to the user.
977 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
978 from debug.c --> eval.c
980 * eval.h, eval.c (scm_eval_options_interface): New options
982 (SCM_EVAL_STACK): New option: Size of newly created stacks,
983 i.e. stacks for new threads.
985 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
987 * eval.c (unsafe_setjmp): Removed with #if 0.
989 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
992 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
993 to avoid compiler warnings.
995 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
997 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
999 * throw.c (handler_message): Print message on current error port
1000 instead of default error port. (Thanks to Maciej Stachowiak.)
1002 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
1004 * ports.c (scm_add_to_port_table): allocate in units of
1005 struct scm_port_table *, not struct scm_port_table.
1006 * posix.c (scm_close_pipe): remove the port from the port table
1008 Thanks to Rob Engle for both fixes.
1010 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1012 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
1013 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.

1017 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
1019 * backtrace.c (display_error_body, display_backtrace_body),
1020 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
1021 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
1022 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
1023 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
1026 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
1027 don't receive the jmpbuf arg anylonger.
1028 (scm_catch): Don't accept a #f tag.
1029 (scm_throw): Check that key is a symbol.
1030 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
1032 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>

1041 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
1042 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
1043 extra layer of functions around the body and handler of a thread.
1044 This extra layer makes sure that the handler is called in the
1045 dynamic context of the surround (= empty dynwind list), but under
1046 the *dynamic root* of the body. We can not use the dynamic root
1047 of the surround since that root belongs to another thread => stack
1048 is not handled correctly. It may seem ugly to use this extra
1049 layer, but the extra cost in terms of execution time is really
1050 negligible compared to the total amount of time required to create
1051 a thread, and it would reduce maintainability to duplicate the
1052 crucial and complicated steps performed by cwdr.
1054 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
1055 (SCM_ALLOW_INTS): Added thread switching code before interrupts
1056 get re-enabled. The important effect of this is that interrupts
1057 are blocked during thread switching so that thread data structures
1058 don't risk getting messed up by an unfortunate signal.
1059 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
1060 seems to do more aggressive optimization which actually move
1061 instructions around in these macros in a fatal way. Therefore:
1062 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
1063 just superstitious...)
1064 (SCM_TICK): Maybe do a context switch and take care of asyncs.
1065 This macro should be used instead of SCM_ASYNC_TICK since the
1066 latter doesn't do context switches any more.
1068 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
1069 instead of SCM_ASYNC_TICK.
1071 * coop.c, iselect.c: Since thread switches are now performed with
1072 interrupts masked, we can't use the old mechanism of delivering
1073 signals immediately when they arrive. Signals must instead be
1074 delivered when the asyncs run *after* the end of the critical
1075 section in scm_internal_select. But this also means after context
1076 switch so that the signal will be delivered to a different thread.
1077 To avoid this, I have changed the protocol of
1078 coop_wait_for_runnable_thread and friends so that they are allowed
1079 to return the original thread. So, if a signal arrives during
1080 scm_internal_select, we won't any longer be forced do a context
1081 switch, but can remain in the same thread and deliver the signal
1084 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
1085 scm_asyncs_pending and made it global.
1087 * iselect.c: Small fixes.
1089 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
1090 coop_condition_variable_init, coop_condition_variable_wait,
1091 coop_condition_variable_signal): Changed return type from `void'
1092 to `int'. This is to adhere closer to the pthreads interface.
1093 This, in turn, is part of an attempt to provide C versions of the
1094 mutex and condition variable primitives which can be part of a
1095 frontend to COOP or pthreads.
1097 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
1098 coop_condition_variable_destroy): New functions.
1100 * coop-threads.c (scm_wait_condition_variable): Use
1101 coop_condition_variable_wait_mutex.
1103 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
1104 Definitions moved to coop-defs.h.
1106 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
1107 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
1108 scm_cond_destroy): New C interface to mutecis and cond vars.
1110 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1112 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
1114 * iselect.c: Now several threads can wait on the same file
1115 descriptor. The behaviour is compatible with OS select: All
1116 threads waiting for the fd return with the same status.
1118 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1120 * coop-threads.c, threads.h (scm_spawn_thread): New function.
1121 Can spawn a thread from application C code.
1123 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1125 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
1126 gh_doubles2scm): New functions.
1128 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
1130 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
1131 commented-out version of gh_eval_str()
1133 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
1135 * socket.c (scm_bind): free soka after use.
1137 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
1139 * stime.c (tzvar): new variable.
1140 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
1141 avoid memory leaks when allocating.
1143 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
1145 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
1148 * gc.c, tags.h: Doc fixes.
1150 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1152 * eval.c (macro-eval!): Removed. This function was a design bug.
1153 It allowed memoized code to leak out to the scheme level. Most
1154 things that you could do with `macro-eval!' can be done with
1157 1997-12-20 Tim Pierce <twp@skepsis.com>
1159 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
1160 scm_fgets now depends on ftell(3) to know how many bytes were
1163 1997-12-15 Tim Pierce <twp@skepsis.com>
1165 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
1166 dealing with strings.
1168 1997-12-13 Tim Pierce <twp@skepsis.com>
1170 Make %read-line more suitable for implementing read-line efficiently.
1171 * ioext.c (scm_read_line): Strip the terminating newline from a
1172 string, and return a cons of the string and its terminator.
1174 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
1175 of the string that is read is stored in this memory location.
1176 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
1177 * genio.c, genio.h (scm_do_read_line): Update caller.
1178 * ports.h (scm_ptobfuns): Update typedef.
1179 * fports.c (scm_fptob, scm_pipob): Update struct.
1181 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1183 * filesys.c (set_element): Return file descriptor.
1184 (fill_select_type): Return the highest file descriptor.
1185 (scm_select): Tell select about the highest file descriptor. On
1186 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
1187 Therefore the extra overhead for calculating the maximum fd seems
1188 to be more than compensated. Is this correct? In any case,
1189 scm_internal_select will be much faster with this info.
1190 (scm_select, fill_select_type, set_element): Don't accept any kind
1191 of object in the file descriptor list or vector.
1193 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1195 * iselect.c (finalize_fd_sets): Bugfix.
1197 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1199 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1200 when using scm_internal_select (since we might switch to another
1203 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1205 * simpos.c (scm_system): always define: use sysmissing if not
1206 available. Check for HAVE_SYSTEM instead of _Windows (does
1207 Windows lack system or does it have an unusable one?).
1208 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1209 Let the argument be optional: if not supplied, call system(NULL).
1211 * ports.c (scm_close_port): relax the type check from OPPORTP to
1212 PORTP; closing a closed port is allowed.
1214 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1216 * fports.c (scm_fgets): Return if the last char in a chunk is
1217 newline. When fgets returns a string whose length is `size-1', it
1218 is ambiguous whether a whole line was retrieved, so we must check
1219 explicitly whether a line terminator is present.
1221 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1223 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
1224 before taking the CDR. (Thanks to Harald Meland.)
1226 * filesys.c (scm_stat): Slightly optimized.
1228 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
1230 * ports.c (scm_close_port): Make sure the port is open before
1233 * guile-snarf.in: Pass args through to gcc in a way that preserves
1234 whitespace boundaries. (Thanks to Greg Badros.)
1236 1997-12-02 Tim Pierce <twp@skepsis.com>
1238 * stacks.c (scm_frame_procedure): Reverse the logic in the return
1239 statement. (Thanks to Doug Evans for pointing this out.)
1241 1997-12-01 Tim Pierce <twp@skepsis.com>
1243 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
1245 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
1247 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
1248 errno macro expansion of this field name. (errno is a C
1249 preprocessor macro on some systems.)
1251 1997-11-29 Tim Pierce <twp@skepsis.com>
1253 * iselect.c: Doc fix.
1255 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
1257 * init.c (scm_start_stack): Removed initialization of
1258 scm_the_last_stack_var.
1260 * backtrace.h: Declare scm_the_last_stack_var.
1262 * backtrace.c: Define scm_the_last_stack_var.
1264 * root.c (mark_root): Don't mark the_last_stack_var.
1266 * root.h (scm_root_state): Removed the_last_stack_var.
1268 * throw.c: Added #include "fluids.h"
1269 (ss_handler): `the-last-stack' is now a fluid.
1271 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
1272 --> the_last_stack_fluid.
1274 * backtrace.c: Added #include "fluids.h"
1275 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
1276 (scm_backtrace): `the-last-stack' is now a fluid.
1278 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
1279 after scm_init_fluids.
1281 1997-11-28 Tim Pierce <twp@skepsis.com>
1283 * iselect.c: #ifdef USE_THREADS around thread-related includes.
1285 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
1286 DLSYM_ADDS_USCORE to decide whether to add an underscore.
1288 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1290 * iselect.c (coop_next_runnable_thread,
1291 coop_wait_for_runnable_thread): Disable interrupts so that no
1292 async is executed before a potential error_revive.
1293 (scm_internal_select): Disable interrupts during the parts of the
1294 code which manipulate the sleep queue and the file descriptors.
1296 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1298 * Makefile.am: Added iselect.c and iselect.h.
1300 * coop.c (coop_qinit): Initialize fields used by
1301 scm_internal_select.
1302 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1303 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1304 replacement in iselect.c.
1305 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1306 coop_join): If GUILE_ISELECT enabled, use
1307 coop_wait_for_runnable_thread instead of
1308 coop_next_runnable_thread.
1309 (usleep, sleep): New replacements for system functions if
1310 GUILE_ISELECT is enabled.
1312 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1314 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1316 * filesys.c: Added #include "iselect.h". Moved FD-macros to
1317 iselect.h. Implement Scheme level `select' using
1318 scm_internal_select. (See NEWS.)
1320 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1322 * init.c: Call scm_init_iselect.
1324 * iselect.h, iselect.c: New files. Implements
1325 scm_internal_select. (See NEWS.)
1327 1997-11-27 Tim Pierce <twp@skepsis.com>
1329 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1330 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1331 and scm_must_free, since ultimately the string returned will be copied
1332 by scm_makfrom0str anyway. Also, read any characters that may have
1333 been pushed onto the port with scm_ungetc.
1334 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1335 * ioext.c (scm_read_line): Free string after Guilifying it.
1336 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
1338 1997-11-26 Anthony Green <green@hoser.cygnus.com>
1340 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
1342 * gh.h: Safely wrap prototypes for c++ usage.
1344 1997-11-25 Mark Galassi <rosalia@cygnus.com>
1346 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
1347 gh_repl (argc, argv).
1349 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1351 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1352 and to invoke scm_shell().
1353 (gh_launch_pad): took out the loading of boot-9.scm from here,
1354 since it is probably best to let the user control that. In fact,
1355 gh_repl() now invokes scm_shell() which does that.
1357 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1359 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
1362 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
1364 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
1365 yesterday's underscore patch. (Thanks to Marius Vollmer for
1368 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
1370 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
1371 DLSYM_ADDS_USCORE is not defined.
1373 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
1375 * gh_data.c (gh_uniform_vector_length):
1376 (gh_uniform_vector_ref): started implementing the uniform types in
1379 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
1381 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1382 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1384 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1386 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1387 configure.in was changed).
1389 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
1391 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1392 * Makefile.in: Regenerated.
1394 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1396 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1397 OPORT is an `open' port, not an output port.
1399 * filesys.c (scm_close, set_element, get_element, scm_chown,
1400 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
1401 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
1402 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
1403 scm_close_port, scm_port_line, scm_set_port_line_x,
1404 scm_port_column, scm_set_port_column_x, scm_port_filename,
1405 scm_set_port_filename_x, scm_port_mode,
1406 scm_close_all_ports_except, scm_set_current_output_port,
1407 scm_set_current_error_port): Likewise
1408 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1409 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
1411 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
1412 * backtrace.c (display_backtrace_body): Likewise
1413 * fports (scm_setvbuf): Likewise
1414 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
1415 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
1416 scm_getpeername, scm_send, scm_sendto): Likewise
1417 * unif.c (scm_uniform_array_write): Likewise
1419 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
1421 Minor problems with substring-related tag changes.
1422 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1423 exactly what we want to leave in to detect substrings.
1424 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1425 * tags.h: Fix diagrams and comments describing the S tag bit;
1426 remove vestigial remarks about the D tag bit.
1427 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
1428 * strings.c: Formatting tweaks.
1430 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1431 variable first; then SCHEME_LOAD_PATH, with a warning message.
1432 (scm_parse_path): New function.
1433 * script.c: Doc fixes.
1435 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1437 Readline support, from Daniel Risacher.
1438 * readline.c, readline.h: New files.
1439 * init.c: #include "readline.h".
1440 (scm_boot_guile_1): Call scm_init_readline, if we have it.
1441 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1442 * Makefile.in: Regenerated.
1443 * scmconfig.h.in: Regenerated, after change to ../configure.
1445 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1447 * gh.h: gh_vector_set -> gh_vector_set_x
1449 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1451 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1452 with the ! -> _x mapping when going from Scheme to C.
1454 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1456 * gh.h (gh_reverse):
1464 (gh_assoc): added these gh_ functions implemented as macros.
1466 * gh_predicates.c (gh_null_p):
1467 (gh_string_equal_p): added these two missing predicates.
1469 * gh_list.c (gh_append):
1474 (gh_set_cdr_x): added these routines as I go through and try to
1475 complete the picture R4RS functions that should be mirrored in the
1478 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1480 * tags.h (scm_tc7_substring): Changed the comment and code to
1481 conform with the changes below. Folks! We have suddenly two new
1482 free tc7 codes!!! Jummy, jummy!
1484 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
1486 * Makefile.in: Rebuilt.
1487 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
1489 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
1490 * unif.c (scm_vector_set_length_x): Don't handle multibyte
1492 * tag.c (scm_utag_mb_string, scm_utag_mb_substring): Removed.
1493 (scm_tag): Don't handle multibyte strings.
1494 * read.c: Don't include mbstrings.h.

1504 * eq.c (scm_equal_p): Use SCM_TYP7S, not SCM_TYP7SD.
1505 * tags.h (SCM_TYP7SD): Removed.
1506 (SCM_TYP7D): Removed.
1507 (scm_tc7_mb_string): Removed.
1508 (scm_tc7_mb_substring): Removed.
1509 * print.c (scm_iprin1): Handle char printing directly. Don't
1511 Don't include "mbstrings.h".
1512 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
1513 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
1515 Don't include "mbstrings.h".
1516 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
1517 (SCM_SYMBOL_SLOTS): Define as 4.
1518 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
1519 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,

1533 (scm_gen_putc, scm_gen_puts, scm_gen_write, scm_get_getc):
1535 (scm_putc, scm_puts, scm_lfwrite): No longer static.
1536 (scm_getc): No longer static; handle line and column changes.
1537 (scm_ungetc): Renamed from scm_gen_ungetc.
1538 (scm_do_read_line): Renamed from scm_gen_read_line.
1539 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
1540 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
1542 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1544 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1546 * gh_test_c.c (c_vector_test): some improvements on the vector
1549 * gh.h (gh_vector): this used to exist but do the wrong thing.
1550 Now it (almost) does the right thing, though it takes a list
1551 instead of the individual arguments. I need to see how it could
1553 (gh_list_to_vector): added this function as a macro. Corresponds
1554 to Scheme's (list->vector ...).
1555 (gh_vector_to_list): added this function as a macro. Corresponds
1556 to Scheme's (vector->list ...).
1558 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1559 gh_vector_ref, so that it resembles the Scheme routines more.
1560 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1561 resembles the Scheme routines more.
1562 (gh_make_vector): this used to be (stupidly) called gh_vector().
1563 This is the right name, since it does the same thing as the Scheme
1564 (make-vector ...) procedure.
1566 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1568 * ports.h: #include "libguile/print.h"
1570 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
1571 Some indentation fixes.
1573 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
1574 longer a user field; New field: class_flags.
1576 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
1578 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
1580 * gh_data.c (gh_bool2scm): new function which replaces
1581 gh_int2scmb(), which is now tagged as obsolete.
1583 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1585 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1586 macros should by convention not test for NIMPness.)
1587 (SCM_COERCE_OPORT): Adjust indentation.
1589 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1590 SCM_NIMP test before SCM_PRINT_STATE_P.
1592 * struct.c, struct.h, gc.c: Renamed:
1593 scm_struct_i_layout --> scm_vtable_index_layout
1594 scm_struct_i_vcell --> scm_vtable_index_vcell
1595 scm_struct_i_vtable --> scm_vtable_index_vtable
1596 scm_struct_i_printer --> scm_vtable_index_printer
1597 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1599 * struct.c (scm_print_struct): Use new printer slot; Default
1600 printing: Also output hex code of vtable so that type identity
1601 will be indicated as well.
1602 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1603 Removed struct_printer_var; Removed struct-vtable-offset;
1604 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1605 vtable-offset-user): New constants.
1607 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
1608 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
1609 If this slot contains a procedure, use that to print structures of
1610 the type represented by this vtable.
1612 * print.c (scm_iprin1): Don't print arguments of macro
1613 transformers. (They are always: exp env.); Bugfix: Unmemoize
1614 transformer source with correct environment.
1616 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1618 Streamlining of call-with-dynamic-root:
1620 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
1621 there is now only one catch.
1622 (cwdr_outer_body): Removed.
1623 (cwdr_handler): New function.
1624 (scm_internal_cwdr): New function to perform the function of cwdr
1625 but take args that are more useful to C code. Also, the handler
1626 is now invoked *outside* of the new dynamic root, like the docs
1627 say. We no longer have to catch absolutely all errors, the caller
1628 is responsible for using a handler that does not throw, if he
1630 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1631 * root.h (scm_internal_cwdr): New prototype.
1633 Even more but risky streamlining:
1635 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1636 allocation of the jumpbuf of a root continuation. The changes
1637 below are controlled by it. They are now deactivated.
1638 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1639 the JMPBUF of the scm_rootcont to NULL before returning.
1641 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1642 when they are non-NULL.
1643 (scm_gc_mark): Likewise, mark only when non-NULL.
1645 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1646 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1648 * gc.c (scm_done_malloc): New function.
1649 gc.h (scm_done_malloc): New prototype.
1651 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
1652 (struct scm_print_state) [revealed]: New field.
1653 (scm_print_state_vtable): Make visible to the outside world for
1654 type checking purposes.
1655 (scm_valid_oport_value_p): New prototype.
1657 * print.c (scm_valid_oport_value_p): New function to check whether
1658 a certain value is acceptable as a port argument.
1659 (scm_print_state_vtable): New variable.
1660 (scm_free_print_state): Set `revealed' field to false.
1661 (scm_iprin1): Call user supplied closure printer with
1662 scm_printer_apply. Print in the traditional way when there isn't
1663 one or when it returns #f.
1664 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1665 Accept a port/print-state pair in addition to just a port.
1666 (scm_prin1): Don't return the print_state to the pool when it has
1668 (scm_printer_apply): Set `revealed' field of print_state to true.
1669 (scm_init_print): Set scm_print_state_vtable.
1670 (print_state_fluid, print_state_fluid_num): Removed.
1672 * throw.h (scm_handle_by_proc_catching_all): New prototype
1673 throw.c (scm_handle_by_proc_catching_all): New function
1675 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1677 * Makefile.in: Regenerated with automake 1.2c.
1679 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1681 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1682 was looping endlessly.
1684 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1686 * strports.c (scm_eval_string): Don't close the port.
1688 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1689 former returns a nice normal integer. (Thanks to Daniel
1692 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1694 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1695 makefile variable as a build parameter called LIBS. The
1696 build-guile program will use this, for the time being.
1697 * Makefile.in: Regenerated.
1699 Thanks to Shiro Kawai:
1700 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1701 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1704 * Makefile.in: Regenerated with automake 1.2a.
1706 * script.c (scm_compile_shell_switches): If we hit the -c or --
1707 arguments, don't set the car of (command-line) to scm_usage_name,
1708 the prettified name of the guile executable; give it the full
1709 path, the way shells usually handle $0.
1711 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1713 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1714 Scheme-level name `array-map' and renamed `serial-array-map' to
1715 `serial-array-map!'.
1717 * backtrace.c: Introduced exception handlers which now enclose
1718 `display-error' and `display-backtrace' so that error reporting
1719 won't get into infinite loops if an error occurs during displaying
1720 of the error. This can very easily happen with user supplied
1721 print call-back routines.
1723 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1725 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1726 the names `serial-array-map' and `array-map' should be removed.)
1728 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1730 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1731 Added #include "objects.h"
1733 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1734 Add #include "feature.h".
1736 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1737 (modinclude_HEADERS): Added objects.h.
1739 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1740 This test is needed at many places in the code and should be
1741 abstracted. (Motivated by the need of this test in libguiletk.)
1743 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1744 (scm_eval_string), load.c (scm_primitive_load,
1745 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1746 Use SCM_EOF_OBJECT_P.
1748 * eval.c (scm_init_eval): Add feature `delay'.
1750 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1752 * scmhob.h: Removed.
1754 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1756 * list.h (SCM_LISTn): New macros. Make list creation in C code
1757 prettier. The idea comes from STk.
1759 * sequences.h, sequences.c, append.h, append.c: Removed. These
1760 files implemented non-R4RS operations which would encourage
1761 non-portable programming style and less easy-to-read code.
1763 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1766 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1767 sequences.h, #include append.h.
1769 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1772 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1774 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1776 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1778 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1780 * eval.c: Added #include "objects.h"
1782 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1785 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1786 adjacent smob numbers.
1788 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1790 * procprop.h: Added declaration of scm_i_inner_name.
1792 * gsubr.c: New global symbol scm_i_inner_name.
1794 * debug.c (scm_procedure_name): Try procedure property
1795 `inner-name' if `name' fails.
1797 * print.c (scm_iprin1): Use scm_macro_name.
1799 * eval.c (scm_m_define): Give names to macros as well; Only the
1800 first top-level definition gives a procedure/macro a name.
1801 Otherwise confusing names can turn up in backtraces.
1802 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1803 `name'; Give names to macros as well.
1805 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1806 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1809 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1811 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
1813 (prinmacro): Removed. The code has been moved/merged into print.c
1814 in order to decrease code redundancy. We want macros to print in
1815 a way equivalent to procedures, and it would be silly to duplicate
1816 the required code. (We don't want to maintain two places.)
1817 (macrosmob): Print field is now a NULL pointer.
1819 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1820 scm_macro_transformer): New prototypes.
1821 (scm_tc16_macro): Declared.
1823 * * print.c (scm_iprin1): Added code for printing of macros. Macros
1824 are now printed in a way equivalent to procedures.
1826 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1828 * procs.h (scm_closure_p): Added declaration.
1830 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1832 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
1833 Shouldn't pass "heap" as the subr name.
1835 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1837 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
1838 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
1839 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1840 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1841 SCM_BOOL_T. Any non-false value is true.
1843 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1845 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1846 scm_gensym): Added prototypes.
1848 * symbols.c (scm_gensym): New function. This will speed up
1849 certain types of applications (such as macro systems) which
1850 generate lots of symbols.
1852 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1854 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
1856 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
1858 * unif.c (scm_shap2ra): tighten the checking of the array dimension
1859 specifier, since (2) or (2 . 3) would cause SEGV.
1860 (scm_transpose_array): more argument checking fixes.
1862 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1864 * Makefile.in: Regenerated.
1866 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1868 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
1870 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1872 * error.c, error.h (scm_error_callback): Removed (see NEWS).
1874 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
1876 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
1877 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
1880 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
1881 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1882 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
1883 scm_array_p, scm_array_rank, scm_array_dimensions,
1884 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
1885 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
1886 scm_array_prototype): Added case scm_tc7_wvect.
1888 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
1890 * errno.h: prototype for scm_strerror.
1891 * error.c (scm_strerror): new procedure.
1893 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1895 * list.c (scm_list_append_x): Allow non-pair as last argument.
1896 This is consistent with the R4RS append and is probably the
1897 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1899 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1901 * stime.h: prototype for scm_times.
1902 * stime.c (scm_times): new procedure.
1903 * ioext.c (scm_fseek): if the first argument is a file descriptor
1905 (scm_ftell): if the first argument is a file descriptor call lseek
1907 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
1908 * filesys.c (scm_chmod): if the first argument is a file descriptor,
1910 (scm_chown): if the first argument is a port or file descriptor,
1912 (scm_truncate_file): new procedure.
1913 Add DEFER/ALLOW INTS to a few other procedures.
1914 (scm_fsync): new procedure.
1915 (scm_open_fdes): new procedure.
1916 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
1918 (scm_fcntl): the first argument can now be a file descriptor. The
1919 third argument is now optional.
1921 * posix.c (scm_execl, scm_execlp): make the filename argument
1922 compulsory, since omitting it causes SEGV.
1923 (scm_sync): return unspecified instead of #f.
1924 (scm_execle): new procedure.
1925 (environ_list_to_c): new procedure.
1926 (scm_environ): use environ_list_to_c. disable interrupts.
1927 (scm_convert_exec_args): take pos and subr arguments and
1928 improve error checking.
1930 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1932 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1933 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1934 argument to SCM_ASSERT. Furthermore, the name of the function
1935 should be passed as first argument when signalling
1936 SCM_WNA. (Thanks to Thomas Morgan)
1938 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1939 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1940 dispatches on the number of actual args has a default case
1941 reporting an internal error. This is a vestige from a version
1942 that mallocated a SCM vector to hold the arguments. In the
1943 current version this check is too late: if it ever happens we will
1944 have already overstepped the bounds of the array.
1946 Also, the patch [...] adds a check for too many actual arguments."
1948 mdj: Removed check for "internal programming error".
1950 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1952 * gh_io.c (gh_write): New function.
1954 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
1955 throw.c (scm_internal_stack_catch): New sibling to the other catch
1956 functions. Code moved from gh_eval.c.
1957 throw.h: Added header.
1958 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
1959 scm_internal_stack_catch.
1961 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1963 * ioext.h: fix up prototypes.
1964 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
1965 Scheme name is now dup->fdes.
1966 (scm_dup_to_fdes): make the second argument optional and
1967 fold in the functionality of scm_primitive_dup.
1968 (scm_primitive_dup): deleted.
1970 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1972 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
1973 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
1974 ultrix are defined. Use setvbuf instead of setbuf.
1975 (scm_setvbuf): new procedure.
1976 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
1977 (scm_setfileno): moved from ioext.c.
1978 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
1979 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
1981 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1983 * fluids.c (scm_fluid_p): New function.
1984 * fluids.h (scm_fluid_p): New prototype.
1986 Sat Jul 26 21:33:37 1997 Marius Vollmer <mvo@zagadka.ping.de>
1988 * print.c (scm_iprin1): Enter printed structures into the print
1989 state as nested data while they are printed.
1990 (print_state_fluid, print_state_fluid_num): New variables.
1991 (scm_init_print): Initialize them.
1992 (scm_iprin): If print_state_fluid carries a print_state, use that
1993 instead of creating a new one.
1994 (scm_printer_apply, apply_stub, struct apply_data): New
1995 definitions to help with calling printer functions written in
1997 * print.h (scm_printer_apply): New prototype.
1999 * struct.c (scm_print_struct): Use scm_printer_apply to call the
2000 user defined struct printer.

2010 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
2011 SCM_ASSERT: arg comes before pos.
2013 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2015 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
2016 to a list of length zero correctly.

2034 * ioext.h: removed scm_duplicate_port prototype.
2036 * ioext.c (scm_primitive_dup2): return the new file descriptor
2037 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
2039 (scm_fdopen): bug fix: don't try to make port unbuffered until its
2040 stream has been set.
2041 (scm_duplicate_port): deleted, there's now an implementation in
2043 (scm_primitive_dup2): do nothing if newfd == oldfd.
2045 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
2047 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the

2056 * ports.h: prototypes too.
2057 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
2059 * fports.h: prototype too.
2060 * fports.c (scm_evict_ports): moved from ioext.c.
2062 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2064 * ports.c (scm_close_port): return a boolean instead of unspecified.
2065 throw an error if an error other than EBADF occurs.
2067 * filesys.h: scm_close prototype.
2068 * filesys.c (scm_close): new procedure, can close file descriptors
2069 and ports (scsh compatible).
2071 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
2074 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
2076 * fluids.c, fluid.h: New files.
2077 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".

2088 unique for the new root when it has a parent.
2090 * smob.h: Include "libguile/print.h" to make scm_print_state
2093 * dynl.c (free_dynl_obj): New function to free the dynamic object
2094 data. (dynl_smob): Use it.
2095 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
2096 the dynamic object data below the linking of the object to avoid
2097 memory leak when the linking code throws an error. Now the code
2098 leaks a whole dynamically linked library when must_malloc throws,
2099 but that should be much less likely.
2101 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
2103 Changes to compile under gnu-win32, from Marcus Daniels:
2104 * stime.c (tzset): If tzset isn't provided, make it a NOP.
2105 (scm_localtime): Change SCM_EOF to SCM_EOL.
2106 (scm_mktime): Likewise.
2107 * socket.c: Don't include sys/un.h unless autoconf tells
2108 us Unix domain sockets are available.
2109 (scm_fill_sockaddr): Ignore Unix domain code.
2110 (scm_addr_vector): Likewise.
2111 (scm_init_addr_buffer): Likewise.

2114 * simpos.c (SYSTNAME): Treat cygwin like Unix.
2115 * scmsigs.c (scm_pause): Don't include unless pause was found
2117 * posix.c (scm_getgroups): Don't include unless support function
2118 was found during autoconf (in this case, getgroups).
2119 (scm_setpwent): For setpwent.
2120 (scm_setegid): For setegid.
2121 * net_db.c (scm_inet_netof): Don't include unless support
2122 function was found during autoconf (in this case, inet_netof).
2123 (scm_lnaof): For inet_lnaof.

2137 scm_misc_error, not SCM_EOF.
2139 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
2140 arguments for formatting the error message, not SCM_BOOL_F. I
2141 think this is left over from the (eq? '() #f) days.
2143 * read.c (recsexpr): Give this a dummy definition if
2144 DEBUG_EXTENSIONS isn't #defined.
2146 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
2148 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

2158 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
2159 alloca.lo will be included in @LIBLOBJS@. Something better than
2160 this should be possible.
2161 * Makefile.in: Regenerated.
2163 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2165 * simpos.h: prototype for scm_primitive_exit.
2166 * simpos.c (scm_primitive_exit): new procedure, terminates the
2167 process without unwinding the stack.
2169 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
2171 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
2172 argument and logior its components together, so the user doesn't
2173 have to do this explicitly. Also, if regexp/basic is supplied, then
2174 turn off REG_EXTENDED.
2175 (scm_init_regex_posix): New regexp/basic symbol.
2176 (REG_BASIC): #define this if it is not already present.
2178 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

2192 * Makefile.in: Regenerated.
2194 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
2195 flag; I don't think we support it.
2196 (scm_make_regexp): Make sure the user doesn't pass the
2199 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
2201 (scm_init_regex_posix): Define constants for the REG_mumble flags;
2202 name them according to the SCSH convention: regexp/mumble.
2204 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.

2209 Makefile directory variables. Print a message, but don't print
2211 (versiondat.h): Print a message, but don't print all the commands.
2212 * load.c: #include "alist.h".
2213 (init_build_info): New function.
2214 (scm_init_load): Call it.
2215 * Makefile.in: Regenerated.
2217 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
2219 * root.c: Establish a reliable catch-all handler for the new root.
2220 After all the Scheme handler function might signal an error too,
2221 and we don't want to lose that.
2222 (cwdr_inner_body): Renamed from cwdr_body.
2223 (cwdr_outer_body): New function, to establish the user's handler,
2224 and pass control to cwdr_inner_body.
2225 (cwdr): Establish the reliable catch-all handler here, and pass
2226 control to cwdr_outer_body.
2227 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
2228 the user's handler through to cwdr_outer_body.
2229 * throw.c (scm_handle_by_message): Move guts into....
2230 (handler_message): New static function.
2231 (scm_handle_by_message_noexit): New function.
2232 * throw.h (scm_handle_by_message_noexit): New prototype.
2234 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
2235 across this. Only works on GCC. Otherwise, we hope for the best.
2236 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2237 the feeling that real thread systems will not need this...
2239 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2241 Try to detect when people are using one version of libguile and a
2242 different version of ice-9. People have been skewing things and
2243 sending in bug reports.
2244 * Makefile.am (versiondat.h): New file to generate.
2245 * version.c: #include "versiondat.h", to get version info.

2249 * scmconfig.h.in, Makefile.in: Regenerated.
2250 * Makefile.in: Regenerated.
2252 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
2253 primitive definitions under their Scheme names.
2255 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2256 1:2. Helps avoid confusion between installed and uninstalled libs.
2258 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2261 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2262 backslash from definition; this should be used like: GDB_INTERFACE;
2264 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2266 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
2267 new port unbuffered until its stream has been set.
2269 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2271 * ports.h: new prototype.
2272 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
2274 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
2276 Make things compile neatly under Sun's C compiler.
2277 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
2278 * extchrs.c (xmbtowc): Make the second arg a normal char, not
2279 unsigned, because that's what the ANSI function takes.
2280 * extchrs.h (xmbtowc): Corresponding change to prototype.
2281 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2283 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2284 argument plain char *.
2285 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2287 * tag.c (scm_tag): Remove unreachable statement.
2288 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2289 top of the word, it should be unsigned.
2291 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2292 is defined, to avoid warnings; it's only used in the
2293 conflict-checking code. Which might go away anyway.
2294 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2295 conditionals; put the label definition in an #if too, to stifle
2298 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2299 ChangeLog-threads in the distribution.
2300 * Makefile.in: Regenerated.
2302 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2304 * guile-snarf.in: Changed regexp to support CPPs that insert
2305 whitespace between lexical tokens (which munges the `%%%' snarf
2308 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2310 * load.c (scm_init_load_path): Append $(datadir)/guile to
2311 %load-path, so modules do not have to be installed in Guile's
2312 current version directory.
2314 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2316 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2317 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2318 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2319 call the sysdep functions with deferred ints.
2320 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2321 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2322 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2325 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2328 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2330 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2332 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2334 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2337 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2339 * eval.c (scm_lookupcar1): New procedure to cope with a race
2340 condition during lookup (when using threads).
2341 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2342 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2345 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2347 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2348 supplied. (Change from Tim Pierce.)
2350 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2352 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2353 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2354 default and not `()'. `#f' is the canonical non-value in Scheme,
2357 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2359 * struct.c (struct_printer): New variable that holds a handle on
2360 the Scheme variable *struct-printer*. This variable can be set by
2361 Scheme code to override the printing of structures.
2362 (scm_print_struct): If struct_printer is set, call it. If it is
2363 not set, or returns #f, print the structure in the old fashion.
2364 Include "eval.h" for scm_apply.
2366 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2368 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2369 scm_struct_i_n_words to get the number of fields, not
2370 -scm_struct_n_extra_words.
2372 On the route to fancier struct printing:
2373 * struct.c (scm_print_struct): New function to print a structure.
2374 Include "genio.h" to support it. This function doesn't do
2375 anything interesting right now, but I think it should be here
2377 * struct.h: Include "print.h" and add prototype for
2379 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2380 print structures ourself.
2382 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2384 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2385 before applying the handler in case it doesn't return.
2387 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2389 * scmsigs.h, async.h: updated.
2391 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2394 * posix.c (scm_uname): interpret only negative values as an error.
2395 Solaris normally returns a positive value.
2397 * script.c (scm_compile_shell_switches): if we are not going into
2398 an interactive repl, set scm_mask_ints to zero so that asyncs can
2401 * simpos.c (scm_system): don't ignore/unignore signals around
2404 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2407 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2408 done in boot-9.scm instead.
2410 * scmsigs.c, async.c: Major rewriting of signal handling code.
2411 (scm_sigaction): new procedure.
2412 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2414 (scm_raise): return unspecified, throw error on failure.
2416 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2418 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2419 feature, to help boot-9.scm decide whether to import the regex
2422 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2424 * eval.c: Include scmconfig.h at the beginning of the file so that
2425 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2428 * regex-posix.c: #include "_scm.h" before conditionally #including
2429 <regex.h>; the former defines HAVE_REGCOMP.
2431 * regex-posix.c: #include <regex.h> conditionally, so the file is
2432 CPP'able (for dependency scanning) even on systems that don't have
2435 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2437 Add new R4RS-compliant syntax for keywords.
2438 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2439 regardless of the setting of the `keywords' read option.
2440 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2441 can be re-read no matter what the setting of the `keywords' read
2444 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2446 Add support for POSIX regular expressions.
2448 * regex-posix.c, regex-posix.h: New files. (Some code
2449 is taken liberally from rx/rgx.c in the old Guile dist.)
2451 * init.c: Include regex-posix.h.
2452 (scm_boot_guile_1): Call scm_init_regex_posix.
2454 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2455 Add regex-posix.[ch] sources.
2456 * Makefile.in: Regenerated.
2458 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2459 to do this automatically? It didn't for me, bleh.)
2461 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2463 * fports.c (print_pipe_port): New function.
2464 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2465 latter doesn't even take the right arguments.
2467 * Makefile.am: Increment shared lib revision number. I think
2468 sometimes the uninstalled Guile finds the installed shared lib;
2469 Gord says doing this might help. As things turned out, I can't
2470 say whether it does.
2471 * Makefile.in: Regenerated.
2473 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2474 passing it as the closure argument to scm_boot_guile. (Bill
2477 * ports.c (print_void_port, putc_void_port, puts_void_port,
2478 write_void_port, flush_void_port, getc_void_port, close_void_port,
2479 noop0): Use ANSI prototypes instead of K&R declarations, so the
2480 initialization of void_port_ptob gets aggressively type-checked.
2481 Fix arguments of print_void_port and write_void_port. (Bill

2517 * script.c (scm_find_executable): Use prototype-style definition
2518 here; apparently it's not quite right to have const in a prototype
2519 and then use a K&R declaration. I wonder if stuff like this will
2520 go away if we compile with -Wrequire-prototypes, or whatever that
2521 is... (Bernard URBAN)
2523 * scmhob.h: New text from Bernard URBAN.
2525 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2527 * script.c: Don't #define const on hpux. Configure takes care of
2528 this. (Thanks to Larry Schwimmer.)
2530 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2531 decide whether to #include <unistd.h>, instead of listing a bunch
2532 of systems. Don't #include stdio twice. Removed dyked-out
2533 definition of scm_find_impl_file.
2535 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2537 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2538 library version info to 1:0.
2539 * Makefile.in: Regenerated.

2547 significantly in 1997, but only had copyright years for 1996.
2548 Also, change name of copyright holder on some from Mikael
2549 Djurfeldt to Free Software Foundation; he has signed papers
2550 assigning the changes to the FSF.
2552 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2553 reason not to give the user the option.
2555 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2556 Return #f on end-of-file when scanning table (i.e. when called
2557 with no arguments). Try to catch errors, when we can.
2558 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2560 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2561 external declarations. These are useful.
2563 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2565 * posix.c: don't include <sys/select.h> or define macros for
2566 select, since they were not used in this file.
2568 * filesys.c (scm_select): make the fifth parameter microseconds,
2569 not milliseconds. let the fourth parameter be either a real value
2570 or an integer or #f. The first, second and third arguments can
2571 now be vectors: the type of the corresponding return set will be
2573 (set_element, get_element): new static procedures.
2575 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2577 * strports.c (scm_eval_string): New function.
2578 (scm_eval_0str): Trivially re-implemented in terms of
2580 * strports.h (scm_eval_string): New extern decl.
2582 * net_db.c (h_errno): Add extern decl for this.
2584 * fports.c (local_pclose): New function.
2585 (scm_pipob): Use it in the initializer here.
2588 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2589 Use a meaningful error message when signalling an error. For
2590 this, scm_gethost must check h_errno rather than errno.
2592 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2594 * Makefile.in: Regenerated, using automake-1.1p.
2596 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2598 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2599 not SCM_UNSPECIFIED.
2601 * script.c (scm_compile_shell_switches): don't append (quit) if
2603 (scm_shell): call scm_exit_status and exit on the result of the
2606 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2608 Ensure that shared substrings are handled properly when passed to
2609 a system call or other foreign function. Many thanks to Tim
2611 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2612 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2613 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2614 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

2616 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
2617 (scm_display_error_message): use RO macros when strings may be RO.
2618 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
2619 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
2620 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

2624 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
2625 scm_strftime), vports.c (scm_make_soft_port): use
2626 SCM_COERCE_SUBSTR to make sure shared substrings are
2629 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2631 * error.c (scm_error): Add newline to error message.
2633 * init.c (scm_init_standard_ports): Doc fix.
2635 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2637 * dynl-shl.c: Completely replaced with new code from Bernard
2640 * script.c (scm_ice_9_already_loaded): New variable.
2641 (scm_compile_shell_switches): Use it.
2643 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2645 * filesys.c (scm_input_waiting_p): add missing third argument to
2648 * stime.c (scm_localtime): copy the result of localtime before
2649 calling gmtime in case they share a buffer.
2650 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2653 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2655 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2657 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2659 * Makefile.am (check-local): New target, which causes 'make check'
2660 to run gh_test_c and gh_test_repl, with some trivial input.
2661 * Makefile.in: Rgnrtd.
2663 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2665 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2668 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2670 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2671 sure how this was supposed to work.
2672 (scm_async_click): don't send SCM_TICK_SIGNAL.
2673 (scm_init_async): don't initialize %tick-thunk.
2675 * the following change doesn't affect the Scheme interface:
2676 gc-thunk is called at the end of garbage collection. however it's
2677 no longer implemented by pretending it's a signal.
2679 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2680 system async corresponding to scm_gc_thunk.
2681 * async.h: declare scm_gc_async.
2682 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2683 gc-thunk directly, instead of going through a signal handler.
2684 (scm_gc_async): new variable, points to the GC system-async.
2685 (scm_init_async): save the GC async as scm_gc_async instead
2686 of using system_signal_asyncs.
2687 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2689 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2691 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2692 Don't screw up if we're interrupted.
2693 * Makefile.in: Regeneradet.
2695 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2697 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2699 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2700 we're not using AM_INIT_GUILE_MODULE any more.
2701 * Makefile.in: Reneregated.
2703 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2705 Functions for finding variable bindings, grace à Tim Pierce.
2706 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2707 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2709 Get 'make dist' to work again.
2710 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2711 * Makefile.in: Regenerated, like a surry without a fringe on top.
2713 Changes for reduced Guile distribution: one configure script,
2715 * configure.in, configure: Removed.
2716 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2717 real configure script lives.
2718 * Makefile.in, scmconfig.h.in: Regenerated.
2720 * init.c: #include "script.h", to get prototype for script.c's
2723 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2725 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2726 scm_must_malloc, not raw malloc.
2728 * script.c (scm_compile_shell_switches): Dyke out debugging output
2731 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2733 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2735 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2736 system has them. Hope this is safe. Previously
2737 sys/timeb.h was included if HAVE_FTIME was defined or if
2738 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2739 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2741 * ioext.c (scm_setfileno): add missing third argument to
2742 scm_misc_error call.
2744 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2746 * eq.c (scm_equal_p): Correctly compare strings of different
2747 varieties. (Thanks to Tim Pierce.)
2749 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2751 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2752 #! block comment must occur on a line all by itself.
2754 Move most of the guts of shell command processing into libguile,
2755 so guile.c can be very small (and eventuallly auto-generated. (I
2756 mean, generated mechanically, not self-generated. Hmm.))
2757 * guile.c, script.c, script.h: New source files.
2758 * init.c (scm_boot_guile_1): Call scm_init_script.
2759 * libguile.h: #include "script.h".
2760 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2761 targets, for new executable.
2762 (libguile_la_SOURCES): Mention script.c.
2763 (modinclude_HEADERS): Add script.h.
2764 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2765 not dynamic linking is enabled. This is because we're generating
2766 executables now. Move CY_AC_WITH_THREADS call after those, so the
2767 values of cy_cv_threads_libs captures the libs chosen above.
2768 * Makefile.in, configure, aclocal.m4: Regenerated.
2770 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2771 We don't maintain this interface any more, and it just confuses
2774 * alloca.c: #include <scmconfig.h>, not <config.h>.
2775 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2776 it'll get included in disties.
2778 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2780 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2781 be distributed, because they confuse people.
2782 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2784 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2786 * configure.in: check for presence of gethostent (not present on
2787 OpenBSD by default).
2788 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2789 * configure, scmconfig.h.in: Regenerated.
2791 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2793 * backtrace.c (scm_backtrace): Split message string across
2794 newlines properly. GCC is more tolerant of this than other
2797 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
2799 Merge threads directory into libguile.
2800 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
2801 threads.h: New source files.
2802 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
2803 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2805 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2806 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2807 coop-threads.c.cygnus, coop-threads.h.cygnus.
2808 * configure.in: If we're using threads, include threads.o in
2810 * _scm.h, libguile.h: threads.h lives in this directory now.
2811 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2812 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2813 currently used, but brought along for information's sake.
2814 * ChangeLog-threads: log from old 'threads' directory.
2815 * Makefile.in, configure: Rebuilt.
2817 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2819 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2822 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2824 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2826 Merge GH interface library into libguile.
2827 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
2828 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2829 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2830 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2832 (EXTRA_libguile_la_SOURCES): ... here.
2833 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2834 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2835 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2836 New variables, describing how to build the gh test programs.
2837 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2838 build the test programs, and we probably should have been linking
2839 libguile.la against them all along, to support AIX shared libs.
2840 Add cflags for threads to CFLAGS; add libs for threads to new
2841 variable THREAD_LIBS, used in Makefile.am.
2842 * ChangeLog-gh: log from old `gh' subdirectory.
2843 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2845 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2847 * acconfig.h: Undo change of Apr 9; including the definition of
2848 PACKAGE in the guile headers conflicts with applications' own
2850 * scmconfig.h.in: Regenerated.
2852 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
2854 * filesys.c (scm_fcntl): New function from Roland McGrath.

2856 * filesys.h: Added prototype.
2858 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
2859 when PROC is receiving no arguments.
2861 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2863 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2864 have S_IFSOCK. This is the case under Ultrix.
2866 * posix.c (scm_status_exit_val, scm_status_exit_val,
2867 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2868 Ultrix versions of WIFSTOPPED, etc., which assume that their
2869 arguments are lvalues (hmm).
2871 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2873 * eval.c: Doc fixes.
2875 * throw.c: Doc fixes; rearranged.
2877 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
2879 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
2881 * acconfig.h: Added entry for PACKAGE.
2882 * scmconfig.h.in: Regenerated.
2884 Changes to work with automake-1.1n, which has better libtool support.
2885 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2886 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
2888 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
2890 * Makefile.in: Rebuild.
2892 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2894 * stime.c (scm_mktime): take an optional zone argument.
2895 (scm_localtime): check putenv return value.
2896 (scm_strftime, scm_strptime): moved from posix.c. move #include
2898 stime.h, posix.h: update prototypes.
2899 (bdtime2c, setzone, restorezone): new static procedures.
2900 (scm_mktime, scm_strftime): use them.
2901 (scm_strftime): don't call mktime before strftime. Use
2902 filltime for return value.
2903 (filltime): convert NULL zname to #f.
2904 (scm_strptime): return a count of characters consumed, not
2905 the remaining string.
2907 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2909 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
2910 (scm_mktime): likewise.
2912 Uncomment localtime and mktime.
2914 * configure.in: add AC_STRUCT_TIMEZONE.
2916 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2918 * stime.c (scm_init_stime): don't define ticks/sec.
2919 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2920 return value problem and is still portable.)
2922 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2924 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2925 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2926 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2927 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2928 cpp_err_symbols.c): Corresponding changes.
2929 * Makefile.in: Regenerated.
2931 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2933 * posix.c (scm_putenv): don't check HAVE_PUTENV.
2934 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
2935 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
2936 * putenv.c: new file, from sh-utils 1.12.
2938 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2939 since allocation isn't for Scheme objects.
2940 (scm_putenv): copy strings before placing in the environment.
2942 * stime.c (scm_current_time): throw an error if time returns -1,
2943 instead of returning #f.
2944 (scm_get_internal_real_time, scm_get_internal_real_time): use
2945 scm_long2num for return value instead of SCM_MAKINUM.
2947 * stime.h: prototypes updated.
2949 * stime.c (scm_time_in_msec): apparently unused, deleted.
2951 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2953 * configure.in: check for gettimeofday.
2955 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2956 which may be more usefully portable than a gettimeofday interface.
2958 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2960 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
2962 * Makefile.in: Regenerated.
2964 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2966 * stime.c (filltime): recovered static procedure.
2967 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
2970 * posix.h: add prototype for scm_close_pipe, remove prototypes for
2971 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2973 * posix.c (scm_mknod): split the mode argument into type and perms
2974 arguments, like the extra fields returned by stat.
2976 * fports.c (scm_pipob): set the close, free and print procedures.
2977 (scm_close_pipe): new procedure.
2979 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2980 define them in boot-9.scm
2982 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2984 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
2985 wan't defined. Don't include fd.h.
2987 * Previously fd.h was regenerated whenever configure was run,
2988 forcing a couple of files to be recompiled.
2990 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
2991 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
2992 Check for _fileno as well as _file.
2994 * ioext.c: don't fd.h.
2995 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
2998 * Change the stratigy for getting information about errno
2999 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
3000 generating lists of symbols during the build process, which will
3001 not always work, include comprehensive lists in the distribution.
3002 To help keep the lists up to date, the "check_signals" and
3003 "check_errnos" make targets can be used.
3005 * configure.in: don't check for a command to extract errno codes.
3006 * Makefile.am: update file lists, remove errnos.list and errnos.c
3007 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
3008 check_errnos targets.
3009 (CLEANFILES): remove errnos.c and errnos.list, add
3010 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
3011 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
3012 * errnos.default: deleted.
3013 * cpp_signal.c: new file.
3014 * cpp_errno.c: renamed from errnos_get.c.
3015 * cpp_err_symbols, cpp_sig_symbols: new files.
3016 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
3017 * error.c (scm_init_error): #include cpp_err_symbols instead of
3019 * posix.c (scm_init_posix): don't intern signal symbols. #include
3022 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
3024 * strop.c (scm_i_index): allow the lower bound to be equal to the
3025 length of the string, so a null string doesn't always give an error.
3027 * posix.h: new prototypes.
3028 * posix.c (scm_status_exit_val, scm_status_term_sig,
3029 scm_status_stop_sig): new functions, as in scsh. They break down
3030 process status values as returned by waitpid.
3032 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
3034 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
3035 configure doesn't know about it.
3037 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3039 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
3041 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
3042 which defines C variables with global linkage.
3044 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3046 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
3049 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
3051 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
3052 has time to check why this doesn't work well with continuations.
3054 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
3056 * Fix shell syntax error; some shells won't tolerate
3057 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
3059 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3061 * posix.c (scm_uname): throw an error if uname fails instead
3064 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
3066 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
3069 * async.c (scm_ints_disabled): definition moved from error.c.
3071 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3073 * acconfig.h: Removed PACKAGE.
3075 * scmconfig.h.in: Regenerated.
3077 * snarf.h: g++ says it's non-portable not to specify the first
3078 argument in a varargs declaration. I introduced the first
3079 argument by using preprocessor conditionals.
3081 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
3083 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
3084 (scm_freopen): use RO string macros for filename and modes.
3085 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
3087 * posix.c (scm_getgrgid): simplify conversion of name to C string.
3088 (scm_mknod): use RO string macros for path.
3090 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
3091 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
3093 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
3094 use SCM_ROSTRINGP and SCM_ROCHARS.
3096 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3098 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
3101 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
3102 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
3103 support for byte vectors.
3105 * print.c (scm_iprin1): Limit number of vector elements printed
3106 according to pstate->length.
3108 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3110 * backtrace.c (scm_display_error_message): don't segv if message
3113 * error.h: prototype for scm_error_scm.
3115 * error.c (scm_error_scm): new procedure, reimplements scm-error
3116 in C and uses scm_error.
3118 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3120 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
3121 pointer to the Scheme variable read-hash-procedures and intern it
3122 in scm_init_read. Modify scm_read_hash_extend and
3123 scm_get_hash_procedure to use the pointer.
3125 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3127 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
3128 (SCM_KEYWORD_STYLE): defined.
3130 * read.c (scm_read_opts): add a keywords option. This isn't a
3131 boolean option, in case someone wants to add support for DSSSL
3133 Setup scm_keyword_prefix symbol.
3134 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
3136 I've left keyword support disabled by default, since it doesn't
3137 seem to break the module system and it gives R4RS standard behaviour.
3138 It can be reactivated with (read-set! keywords 'prefix).
3140 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3142 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
3143 before constructing arbiter.
3145 * eval.c (scm_m_define): Bugfix: Check that the object is a
3146 closure before setting the procedure property!
3148 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
3150 * ports.c: Removed `ungetc-char-ready?'.
3152 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
3154 * read.c (scm_init_read): intitialise scm_read_hash_procedures
3155 (idea from Mikael: make it a pair so scm_permanent object only
3157 (scm_read_hash_extend): don't call scm_permanent_object.
3158 (ideas from Mikael): if chr is already in the list, replace its
3159 procedure instead of appending it again. If proc is #f, remove
3161 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
3163 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
3165 * gdbint.c (gdb_read): update scm_lreadr usage.
3167 * load.h: update prototypes.
3169 * load.c (scm_primitive_load, scm_read_and_eval_x,
3170 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
3172 * read.h: add prototype for scm_read_hash_extend. Change args for
3175 * read.c (scm_read_hash_procedures): new variable.
3176 (scm_read_hash_extend): new procedure.
3177 (scm_get_hash_procedure): new procedure.
3178 (scm_lreadr): use scm_get_hash_procedure instead of an argument
3179 for extended # processing.
3180 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
3181 scm_read_token): remove case_i, sharp arguments. Change callers.
3183 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
3185 * read.h (SCM_N_READ_OPTIONS): increase to 3.
3186 (SCM_CASE_INSENSITIVE_P): define.
3188 * read.c: add case-insensitive option to scm_read_opts.
3189 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
3190 to determine whether to convert symbol case.
3191 (default_case_i): definition removed.
3192 * read.c (scm_read_token): if case_i, downcase ic before doing
3195 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3197 * configure.in: Added configuration option `guile-debug'.
3198 Configure with --enable-guile-debug if you want a bunch of extra
3199 functions used for debugging when developing Guile.
3201 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3203 * procs.c (make-cclo): New undocumented debugging procedure: Make
3204 compiled closure with internal procedure PROC and length LENGTH.
3205 Only compiled if GUILE_DEBUG is defined.
3207 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3209 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3211 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3213 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3214 with 3 or more args internally to the evaluator.
3216 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3218 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3219 with 3 or more args internally to the evaluator. This is mainly
3220 because we don't want to pass entry and exit points of the
3221 debug support twice, but it also seems to increase the speed of
3222 the evaluator for such calls (e. g. (+ 1 2 3)).
3224 * backtrace.c (scm_display_application): New procedure:
3225 display-application; Set fancy printing parameters individually
3226 for different types of display (backtrace, error, application).
3227 (These should of course be customizable!)
3229 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3230 clear the CHECK-flags.
3232 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3234 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3236 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3238 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3239 from pairs with a GLOC in the car.
3241 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3242 otherwise `symbol-hash' will behave badly.
3243 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3244 we get segmentation fault!
3246 * symbols.c: Added #include "weaks.h". New functions:
3247 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3248 moved to an extraneous library when we split libguile.)
3250 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3252 * filesys.c (scm_stat): stat now takes fport arguments too as
3253 documented in the manual.
3255 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3257 * debug.c (scm_single_step): Bugfix: Call continuation with
3258 scm_call_continuation instead of throwing to it.
3260 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3262 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3263 argument wasn't declared to be optional.
3265 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3267 * stime.c (scm_init_stime): Add feature "current-time".
3269 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3271 * throw.h: prototype for scm_exit_status.
3272 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3273 args to derive an exit status. Allows (quit) to work from a
3275 (scm_exit_status): new function.
3278 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3280 * eval.c (scm_deval): Removed some old code.
3281 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3283 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3286 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3289 * procs.c: Introduce the existent C function scm_thunk_p at the
3290 Scheme level as well.
3292 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3294 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3295 used from C to easily lookup the value of a symbol in the current
3298 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3300 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3301 scm_init_unif in this file. This will also fix a previous problem
3304 * configure.in: Added AM_MAINTAINER_MODE
3306 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3308 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3311 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3313 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3314 source files that are not always included in libguile but should
3315 have their dependencies calculated by automake. This variable is
3316 recognized by automake, no further magic is needed.
3317 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3318 to deal exclusively with *.lo files, as it seems. The *.o files
3319 are built automatically when the corresponding *.lo file gets
3322 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3324 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3327 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3329 * unif.c (scm_array_set_x): minor change to argument error checking.
3331 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3333 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3334 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3335 They should only be included in the library at configure.in's
3337 (libguile_la_LDADD): Include the appropriate .lo files here.
3338 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3339 so we know when to build them (and their .lo bretheren).
3340 * configure.in (LIBLOBJS): New substituted variable. We let
3341 configure decide which .o files to include in LIBOBJS, and then
3342 put the corresponding list of .lo files in LIBLOBJS. The latter
3343 is what we pass to libtool.
3344 * Makefile.in, configure: regenerated.
3346 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3348 * symbols.c (scm_sysintern0): New function. Contains the core of
3349 old scm_sysintern but doesn't take a second value argument.
3350 (scm_sysintern): Now uses scm_sysintern0.
3351 (scm_sysintern_no_module_lookup): Renamed to
3352 scm_sysintern0_no_module_lookup and doesn't take a second value
3353 argument any longer.
3355 * symbols.h (scm_sysintern0: Added declaration.
3357 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3358 scm_sysintern when interning option keys. Otherwise we risk
3359 destroying the values of already interned variables.
3361 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3362 scheme-level boolean (use SCM_NFALSEP).
3364 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3366 (scm_backtrace): New function. (C version of old function from
3367 boot-9.scm) Motivation: Make it possible to display backtraces
3368 without depending on boot-9.scm. (I'm uncertain if this
3369 motivation is good enough...)
3371 * root.h (scm_root_state): Add member the_last_stack_var.
3372 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3374 * root.c (mark_root): Mark scm_the_last_stack_var.
3376 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3379 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3381 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3382 1. mark_lazy_catch didn't mark the smob.
3383 2. Both functions above have standard variants:
3384 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3385 free_lazy_catch --> scm_free0.
3387 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3389 * throw.c (scm_internal_lazy_catch): New function.
3390 (scm_lazy_catch): Rewritten to use it.
3391 (scm_ithrow): Handle the new lazy catch representation.
3392 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3393 that doesn't have a jmpbuf is a lazy catch clause.
3394 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3395 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3396 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3398 (scm_init_throw): Register the new lazy-catch smob type.
3399 * throw.h (scm_internal_lazy_catch): decl for new function.
3401 * throw.c (scm_internal_catch): Doc fixes.
3403 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3404 configure.in. Including this might cause problems if applications
3405 that link against libguile include their own copies of alloca, but
3406 if they're using autoconf, they should be adding libguile to LIBS
3407 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3408 the copy in libguile, and things will be okay. (I think.)
3410 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3412 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3414 strop.h: move prototypes too.
3416 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3418 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3421 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3422 etc. I deleted them from filesys.c long ago, but didn't
3423 notice they were here too (although ineffective since
3424 sys/stat.h wasn't included).
3426 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3428 * eval.c: Don't define alloca in GCC case. gcc will automatically
3429 use __builtin_alloca if appropriate.
3431 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3433 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3434 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3435 that values of automatic variables are preserved. See comments
3436 for safe_setjmp for details.
3438 Change from Thomas Morgan:
3439 * variable.c: Include eq.h.
3440 (var_equal): New function.
3441 (variable_smob): Use var_equal as the discriminator for variables.
3443 * throw.c (s_throw): Remove extraneous declaration.
3445 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3446 * eval.c: Add necessary CPP cruft to support that.
3447 * configure, Makefile.in, scmconfig.h.in: regenerated.
3449 Change from Thomas Morgan:
3450 * procprop.c (scm_procedure_properties): Convert the Scheme
3451 boolean returned by scm_procedure_p into a C boolean before using
3452 it as a condition for SCM_ASSERT.
3453 (scm_procedure_property): Likewise.
3455 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3456 indications of Unixness.
3459 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3461 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3463 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3465 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3466 "unknown # object" error messages.
3468 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3469 (scm_i_index) and declare it static. Add a 'direction' argument
3470 to indicate what way the search should go.
3471 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3473 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3474 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3476 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3478 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3480 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3481 to avoid clash with various scsh forks.
3483 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3485 The following two changes (ramap.c, throw.c) are motivated by the
3486 apparent unportability of forward declarations of static arrays of
3487 the form `static foo bar[];'.
3489 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3490 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3492 * throw.c (scm_throw): Moved above scm_ithrow.
3494 * options.h: Removed the extern declarations of scm_yes_sym and
3495 scm_no_sym since these are static.
3497 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3499 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3501 * Makefile.am: remove AWK=@AWK@.
3502 Add a rule for generating errnos.list.
3503 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3505 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3506 don't extract errnos, just set a variable (avoids the
3507 need to recompile error.c just because configure is run.)
3509 * unif.h: update prototypes.
3510 * unif.c (scm_uniform_array_read,write): change the offset and
3511 length arguments to start and end, for consistency.
3513 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3515 * ioext.h: update prototypes.
3516 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3517 scm_read_line_x, it's a more general procedure using an
3518 interface from scsh. read-line and read-line! are now defined
3520 Note that the new read-line trims the terminator
3521 by default, previously it was appended to the returned string. An
3522 optional argument specifies how to process the terminator (scsh
3523 compatible). For the old behaviour: (read-line port 'concat).
3524 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3525 returns a pair, but is converted to multiple values if the scsh
3528 socket.h: update prototypes.
3529 * socket.c (scm_recvfrom): for consistency with other procedures,
3530 take start and end as separate optional arguments.
3531 (scm_recv, scm_recvfrom): don't allow the second argument
3532 to be a size, only a buffer. Change the scheme names to
3533 recv! and recvfrom!. Don't return the buffer.
3535 * ioext.h, posix.h: move prototypes too.
3536 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3537 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3538 "read.h" and "unif.h".
3539 * ioext.c: include "chars.h"
3541 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3543 * dynl.c: The dynamic linking and module registration functions
3544 are now defined even when dynamic linking is not available for the
3545 host system. Some of their functionality can be done without
3546 dynamic linking; when it's really needed, they throw errors.
3548 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3550 * configure.in: Only define DYNAMIC_LINKING when one of the system
3551 dependent functions is detected.
3552 * dynl.c (scm_dynamic_func): New function to get the address of a
3553 function in a dynamic object.
3554 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3555 produced by scm_dynamic_func as the thing to call.
3557 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3559 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3560 (scm_register_module_xxx, scm_registered_modules,
3561 scm_clear_registered_modules): New functions.
3563 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3565 * symbols.c (scm_sysintern): Renamed to
3566 scm_sysintern_no_module_lookup.
3567 (scm_sysintern): New function to take the place of the old
3568 scm_sysintern. It uses the current toplevel lookup closure to give
3569 the symbol its value. This is a temporary hack to put packages
3570 like gtcltk into their own module.
3571 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3572 us whether `scm_top_level_lookup_closure_var' has been initialized
3574 * eval.c (scm_init_eval): Set it.
3576 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3578 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3579 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3581 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3583 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3584 scm_sys_dup): deleted: FD capability will be added to other
3586 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3587 scm_fd_free, fd_smob, scm_intern_fd.
3588 (scm_open): renamed from scm_sys_open. Return a port instead of
3589 an FD object. Make the mode argument optional.
3590 (scm_sys_create): deleted, it's just a special case of open.
3591 (scm_init_filesys): move interning of constants O_CREAT etc.,
3592 here (were previously using SCM_CONST_LONG macro).
3593 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3595 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3596 include "fports.h" and <stdio.h>
3597 (scm_stat, scm_select): don't support FD objects.
3599 * error.h: adjust scm_syserror_msg prototype.
3600 * error.c (scm_syserror_msg): take an extra argument for errno.
3601 Using the global value didn't always work, since it could be
3602 reset by procedure calls in the message or args arguments.
3604 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3605 I don't understand why the check was there (and what about the
3608 * strop.c (scm_string_copy): allow shared substrings to be copied.
3610 * unif.h: corresponding change to prototypes.
3611 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3612 recognize two new optional arguments: offset and length. Allow
3613 the port argument to be an integer (file descriptor, for scsh).
3614 Include <unistd.h> for "read" prototype.
3616 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3618 * socket.c: don't include filesys.h.
3620 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3622 * Makefile.am: add AWK=@AWK@ (?)
3624 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3626 Add a rule to generate errnos.c from errnos.
3627 * error.c (scm_init_error): include errnos.c.
3628 * errnos_cnvt.awk: new file, converts the list of errno codes to
3630 * errnos_get.c: new file.
3631 * errnos.default: new file, contains errnos to try if they can't
3632 be extracted from errno.h.
3633 * configure.in: if using GCC, try and extract errno codes from
3637 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3639 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3640 * Makefile.am: Made libguile into a libtool library.
3641 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3642 Set libtool_libs to indicate that libguile is a libtool library.
3643 See guile/ChangeLog for details.
3644 * .cvsignore: ignore "*.lo", the libtool library objects.
3646 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3648 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3649 use htons in getservbyport argument.
3651 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3653 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3654 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3657 * objprop.c (scm_object_property): No need to take the CDR of the
3658 value returned by scm_object_properties, since Aug 20 change.
3660 * configure.in: When checking for struct linger, #include
3661 <sys/types.h> as well as <sys/socket.h>. I've never known
3662 <sys/types.h> to cause any portability problems, and Solaris's
3663 <sys/socket.h> needs it.
3664 * configure: Rebuilt.
3666 I think the Sun compiler has chosen a perverse way to interpret
3667 ANSI declarations combined with K&R definitions. We'll
3668 appease it a little bit. But when it invades France, we fight.
3669 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3670 * print.h (scm_iprlist): Here too.
3671 * numbers.c (scm_divbigdig): Change definition to match
3672 declaration in numbers.h.
3673 * unif.c (scm_makflo): Change definition to match declaration in
3676 * init.c (scm_boot_guile): Don't return the value of
3677 scm_boot_guile_1. This function doesn't return a value;
3678 scm_boot_guile_1 doesn't return a value (or return at all).
3680 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3683 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3684 compile. I have a feeling this function is a bad idea anyway ---
3685 one should always test for features, not systems.
3687 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3688 semicolons. Only pure luck kept this from being noticed earlier.
3690 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3692 * socket.c (scm_recvfrom): Added missing semicolon.
3694 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3696 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3697 the buffer and start and end positions for scsh networking
3700 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3702 * configure.in: Revert previous change to this file; the problem
3703 is due to transient automake weirdness.
3704 * configure: Rebuilt.
3706 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3707 PLUGIN/guile.libs. configure generates the latter from the former.
3708 * Makefile.in: Rebuilt.
3710 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3711 need this if we install scripts, like guile-snarf.
3712 * configure: Rebuilt.
3714 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3716 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3718 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3720 * socket.c (scm_addr_vector): fix faulty scm_listify.
3722 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3724 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3725 style block comment is no longer considered an error.
3727 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3729 * PLUGIN/guile.libs.in: New file.
3730 * PLUGIN/guile.libs: Removed from repository.
3731 * configure.in: Create PLUGIN/guile.libs from
3732 PLUGIN/guile.libs.in. This is for including additonal libraries
3733 needed for dynamic linking.
3734 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3735 instead of PLUGIN/guile.libs.
3737 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3739 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3741 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3742 occurrences of the given element from the list, not just the
3743 first. This is how the Emacs Lisp functions behave, how the
3744 analogous Common Lisp functions behave, and (I believe) how the
3745 older Maclisp functions worked. I realize that this change may
3746 break code, but it seemed better to break it before the Guile
3749 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3750 Their prototypes were already present in gc.h, but they weren't
3752 (scm_init_storage): Initialize scm_protects.
3753 * root.c (scm_protects): New element of scm_sys_protects.
3755 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3757 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3759 * libguile.h: Added #include "libguile/net_db.h".
3761 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3762 30 change. That file is only meant for communication between the
3763 configuration process and load.c. If code linked against libguile
3764 wants to get at the paths mentioned in libpath.h, it can call
3765 functions declared in load.h.
3767 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3769 * libguile.h: Removed #include "libguile/fdsocket.h"
3771 * net_db.c: Added #include <sys/socket.h>.
3773 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3775 * filesys.c (scm_input_waiting_p): use select in preference to
3776 FIONREAD, since the latter doesn't detect EOF.
3777 Throw error if neither select nor FIONREAD available.
3779 * socket.c (scm_connect): take a port, not a fd object.
3780 (scm_fill_sockaddr): throw an error if fam is not recognised.
3781 (scm_bind): use scm_fill_sockaddr.
3782 (scm_listen): take a port, not a fd object.
3783 (scm_accept): take and return a port. return #f in the car if
3784 address can't be got
3785 (scm_sock_fd_to_port): new procedure.
3786 (scm_socket): use scm_sock_fd_to_port.
3787 (scm_addr_vector): throw error if unrecognised address type.
3788 take an extra argument with the calling procedure name.
3789 (scm_getsockname): take a port. return #f if address can't be got.
3790 (scm_getpeername): take a port. return #f if address can't be got.
3791 (scm_recvfrom): take a port. return #f for address component if can't
3793 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3794 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3796 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3798 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3799 use separate data pointers, to allow them to be designed
3800 independently and reused.
3801 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3802 Renamed from catch_body, catch_handler, and uncaught_throw; made
3804 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3806 (scm_catch): Use the above.
3807 (scm_throw): Don't bother printing a message for an uncaught
3808 throw; we establish a default handler in init.
3809 * throw.h (scm_internal_catch): Prototype updated.
3810 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3812 (struct scm_body_thunk_data): New structure, used as data
3813 argument to scm_body_thunk.
3814 * init.c (struct main_func_closure): New structure, packaging up
3815 the data to pass to the user's main function.
3816 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3817 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3818 scm_internal_catch to establish a catch-all handler, using
3819 scm_handle_by_message. This replaces the special-case code in
3821 (invoke_main_func): Body function for scm_internal_catch; invoke
3822 the user's main function, using the main_func_closure pointer to
3823 decide what to pass it.
3824 * root.c (struct cwdr_body_data): Remove handler_proc member.
3825 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3826 (cwdr_handler): Removed.
3828 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3830 * socket.h (SCM_P): update bind prototype.
3831 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3832 include "feature.h".
3833 (scm_socket): return a port, not a file descriptor object.
3834 include "fports.h" and <unistd.h>
3835 (scm_bind): take a port, not a file descriptor object.
3836 take an extra argument for address args.
3838 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3839 INADDR_NONE, INADDR_LOOPBACK.
3841 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3843 * init.c: include net_db.h and not fdsocket.h.
3844 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3846 * Makefile.am: corresponding changes.
3847 * socket.h: renamed from fdsocket.h, fix names.
3848 * net_db.h: renamed from socket.h, fix names.
3849 * socket.c: renamed from fdsocket.c.
3850 remove _sys from procedure names.
3851 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3852 add "socket" to features list.
3853 * net_db.c: renamed from socket.c.
3854 remove _sys from procedure names.
3855 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3856 add "net-db" to features list.
3857 include "net_db.h". don't include <sys/socket.h> or
3860 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3862 * tags.h (scm_tags): Removed comma at end of last enumerator.
3864 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3866 Don't use GCC extensions to allocate space for debugging frames.
3867 (Here he goes again! Why do we put up with this?!)
3868 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3869 an scm_debug_info structure, not an in-line array of them. Add
3870 'info' member, to say how many vect elements we've used, for eval
3872 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3873 a new variable debug_info_end to mark the end of vect, instead of
3874 the address of the 'info' pointer itself.
3875 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3876 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3877 (SCM_APPLY): Explicitly allocate space for debug.vect.
3878 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3879 * stacks.c: Adjusted for new debug frame structure.
3880 (RELOC_INFO, RELOC_FRAME): New macros.
3881 (stack_depth, read_frames): Use them, and new scm_debug_frame
3882 element 'info', instead of magically knowing that eval frames have
3883 an info pointer sitting after vect.
3884 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3886 (scm_init_stacks): Formatting tweaks.
3888 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3890 Give GCC more control flow information, so it can be sure that
3891 variables aren't used uninitialized.
3892 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3893 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3894 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3895 scm_misc_error): Tell GCC that these functions never return.
3896 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3897 out the field type, call abort if SCM_ASSERT returns, to placate
3899 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3900 scm_wta ever returns. We can't handle this case anyway, and this
3901 gives the optimizer more information.
3902 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3903 scm_wta ever returns.
3905 In some cases, the code is fine, but GCC isn't smart enough to
3906 figure that out; this usually happens when one variable is only
3907 initialized and used when a particular condition holds true, and
3908 we know that condition will never change within a given invocation
3909 of the function. In this case, we simply initialize the variables
3910 to placate the compiler, hopefully to a value which will cause a
3911 crash if it is ever actually used.
3912 * print.c (scm_iprin1): Initialize mw_pos.
3913 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3914 * throw.c (scm_ithrow): Initialize dynpair.
3915 * unif.c (scm_uniform_vector_ref): Initialize cra.
3916 * struct.c (init_struct): Initialize prot.
3917 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3919 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3920 if EXPR contains no expressions.
3922 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3924 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3925 cause an infinite loop (???). So much for the algebraic
3926 equivalency of variable-sized arrays and alloca...
3928 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3930 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3931 a SCM boolean, not a C boolean.
3933 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3935 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3936 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3937 rules for raising scm_mtrigger. Previously, unfortunate but not
3938 unlikely circumstances could result in almost constant invokation
3939 of the gc. Now, this situations should be less likely, but they
3940 are not prevented completely.
3942 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3944 * numbers.c (scm_fuck): Procedure removed; looks like old test
3946 * numbers.h: Prototype removed.
3948 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3950 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3951 array to a pointer, to match my Nov 21 change in eval.c.
3953 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3955 * libguile.h: Added #include "libguile/backtrace.h", #include
3956 "libguile/stacks.h".
3958 * strings.c (scm_string scm_make_string scm_string_ref
3959 scm_string_set_x scm_string_equal_p scm_string_append):
3960 Bugfix according to scm patch from Aubrey Jaffer:
3961 Corrected long-standing
3962 (not (eqv? (integer->char 128)
3963 (string-ref (make-string 1 (integer->char 128)) 0)))
3964 bug found by John Kozak <jk@noontide.demon.co.uk>.
3966 * strports.c, strports.h: Make scm_eval_0str return the value of
3967 the last expression evaluated (previously, it returned void).
3969 * strports.c, strports.h: New function: scm_read_0str. Does what
3972 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3974 * simpos.c (scm_getenv): return #f if string can't be found in the
3975 environment instead of throwing an exception, for compatibility
3976 with numerous other systems.
3978 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3980 * Makefile.am (.c.x): Use guile-snarf.
3981 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
3983 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
3985 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3987 * backtrace.c (scm_display_error_message): Made non-static, and
3988 renamed from display_error_message.
3989 * backtrace.h (scm_display_error_message): Added extern decl.
3990 * throw.c (uncaught_throw): Use it to display the error message.
3992 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
3994 * inet_aton.c: Use #if 0, not #ifdef 0.
3996 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
3998 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
3999 to convert the returned value.
4000 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
4001 the offset argument.
4003 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4005 Add new interface to catch/throw, usable from C as well as
4007 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
4008 (scm_internal_catch): New function, replaces...
4009 (scm_catch_apply): Deleted.
4010 * throw.c (scm_catch_apply): Deleted; replaced with a more general
4011 mechanism which is a bit more code, but can be used nicely from C
4012 and implement the Scheme semantics as well.
4013 (scm_internal_catch): This is the replacement; it's named after
4014 the analogous function in Emacs.
4015 (scm_catch): Reimplemented in terms of the above.
4016 (struct catch_body_data, catch_body, catch_handler): New
4017 functions, used by scm_catch.
4018 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
4019 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
4020 support for new cwdr.
4022 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
4025 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
4027 * acconfig.h: Added DYNAMIC_LINKING symbol.
4028 * configure.in: Add option and checks for dynamic linking.
4029 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
4030 dynl.h: New files for dynamic linking support.
4031 * Makefile.am (libguile_a_SOURCES):
4033 (modinclude_HEADERS): Added "dynl.h".
4034 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
4036 * init.c (scm_boot_guile_1): Call
4037 scm_init_dynamic_linking to initialize dynamic linking support.
4039 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
4041 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
4042 (as we Schemers say). It needs to be global, so that I can tweak
4043 it for the proper operation of unexec.
4044 (scm_boot_guile_1_live): New variable, see above.
4046 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
4048 * guile-snarf.sh: Removed.
4049 * PLUGIN/guile.libs: Added dependency for -lm.
4050 * acinclude.m4: Renamed from aclocal.m4.
4051 * PLUGIN/greet: Removed.
4052 * Makefile.am, aclocal.m4: New files.
4053 * configure.in: Updated for Automake.
4055 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
4057 * eval.c (scm_definedp): Use top_level_lookup_closure_var
4058 and not top_level_lookup_thunk_var.
4060 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
4062 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
4064 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
4066 * eval.c (scm_definedp): Incompatibly changed to be a builtin
4067 Scheme function, instead of syntax. Single argument is now a
4070 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4072 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
4073 scm_ra_divide): Properly terminate statements passed as arguments
4074 to IVDEP macros. (Thanks to Bernard Urban.)
4076 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
4077 with non-constant sizes. (Thanks to Bernard Urban.)
4079 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4081 It's an "eval closure", not an "eval thunk." A thunk is a
4082 function of no arguments.
4083 * root.h (struct scm_root_state): Renamed
4084 top_level_lookup_closure_var from top_level_lookup_thunk_var.
4085 (scm_top_level_lookup_closure_var): Renamed from
4086 scm_top_level_lookup_thunk_var.
4087 * root.c (mark_root): Uses changed.
4088 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
4089 * init.c (scm_start_stack): Uses changed.
4090 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
4091 Change scheme-visible name to *top-level-lookup-closure* from
4092 *top-level-lookup-thunk*.
4094 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
4096 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
4097 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
4099 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
4101 * gc.c (struct scm_heap_seg_data): Doc fixes.
4103 * gc.c (scm_gc_sweep): Empty all segments' freelists before
4104 sweeping. Then, prepend each segment's free cells to its
4105 freelist, rather than wiping out the old value. (Thanks to Marius
4108 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
4109 scm_check_freelist, scm_debug_newcell): New functions and
4110 variables, for debugging freelist problems.
4111 * pairs.h (SCM_NEWCELL): New debugging version added.
4112 * gc.h (scm_debug_newcell): Added extern declaration, used by
4113 debugging version of SCM_NEWCELL.
4115 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4117 On some systems <libc.h> conflicts with <unistd.h>, and should not
4118 be #included at all.
4119 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
4120 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
4121 * configure.in: Call it.
4122 * posix.c, filesys.c: Use its results to decide whether or not to
4124 * configure, scmconfig.h.in: Rebuilt with autoconf and
4127 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4129 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
4130 pointer to the stdio stream before calling scm_setbuf0, so the
4131 latter will be able to retrieve it. I'm surprised this didn't
4132 segfault earlier. (Thanks to Christopher Lee.)
4134 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4136 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
4139 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4141 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
4142 number of stack narrowing specifier pairs. The first specifier in
4143 a pair controls inner border, the second the outer border. A
4144 number means cut that number of frames, a procedure object means
4145 cut until that object is found in operator position in a frame.
4147 * root.c (cwdr): Bugfix.
4149 * read.c: Recording of positions disabled by default.
4151 * procs.c (scm_closure_p): New function.
4153 * posix.c (scm_tmpnam): New function.
4155 * load.c: Added #include "throw.h".
4156 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
4159 * load.c, load.h (scm_read_and_eval_x): New function.
4161 * eval.c: Renamed debug option "deval" to "debug".
4163 (scm_eval_x): `eval!' is no longer accessible from the scheme
4164 level. Motivation: We can't allow operations which introduce
4165 glocs into the scheme level. Guile's type system can't handle
4166 these as data. Use `eval' or `read-and-eval!' as replacement.
4168 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
4169 SCM_CONSP since this is a macro!; Set vframe.prev to
4170 scm_last_debug_frame instead of 0. In this way we can look
4171 "above" the virtual start stack frame if we wish.
4172 (scm_debug_hang): New function: Useful for debugging Guile in
4173 certain tricky situations. Will probably be removed later...
4175 * debug.h: Changed semantics of debug option "backtrace". This
4176 option now only indicates whether we want automatic backtrace at
4179 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4181 * ports.c: #include "filesys.h"
4182 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
4184 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
4185 Motivation: This is system specific code which is related to file
4186 I/O. It also may use select. Added code by Gary Houston to
4187 detect presence of character in stdio buffers.
4189 * libguile.h: #include "libguile/libpath.h"
4191 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4192 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4193 SCM_SITE_DIR; Install libpath.h among the other include files.
4195 * load.c, load.h (scm_sys_package_data_dir): New function.
4197 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4199 * stacks.h: Bugfix: Don't use tail-array length field as stack
4200 length field! This screwed GC.
4202 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4204 * _scm.h: Added #ifndef around definition of macros min and max.
4206 * __scm.h: Added hooks for threads to plugin to in ints protection
4207 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4208 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4209 the main code in these macros duplicated and spread over multiple
4210 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4211 SCM_THREAD_SWITCHING_CODE.
4213 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4215 * snarf.h: New file.
4216 * guile-snarf.sh: New file.
4217 * Makefile.in (inner_h_files): Added snarf.h
4218 (ancillary, install, uninstall, distclean): Added actions for
4220 (.c.x): Use guile-snarf.
4221 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4222 (gen_c_files): Note that these depend on guile-snarf.
4223 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4224 now in "snarf.h". Added #include "snarf.h" to get them.
4225 * libguile.h: Added #include "snarf.h".
4226 (Patches applied and tweaked by Jim Blandy.)
4228 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4230 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4231 standards suggest against providing prototypes for system
4232 functions. Thanks to Greg Troxel.
4234 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4236 * strports.c (scm_eval_0str): New function.
4237 #include "read.h", to get prototype for scm_read.
4238 * Makefile.in (strports.o): Update dependencies.
4239 * strports.h: New prototype.
4241 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4242 scheme name from "int?" to "integer?". It seems to do the job.
4243 * numbers.h: Rename prototype too.
4244 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4247 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4248 scm_num_eq_p): Rename these according to R4RS conventions: call
4249 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4250 to making libguile R4RS compliant without ice-9...
4252 * load.c (scm_sys_search_load_path): Search for files under all
4253 extensions listed in the %load-extensions variable. If FILENAME
4254 is absolute, return it unchanged, without searching the load path.
4255 (scm_loc_load_extensions): New variable, pointing to
4256 %load-extensions' value cell.
4257 (scm_init_load): Initialize it, and the value it points to.
4258 (scm_primitive_load_path): Improve error reporting.
4260 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4261 of new Scheme variable %load-hook.
4262 (scm_primitive_load): Apply %load-hook to filename.
4264 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4266 * configure.in: add tests for figuring out whether buffered data
4267 is available in a FILE structure, which is needed by char-ready.
4269 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4272 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4273 exceptions using misc_error instead of syserror. It seems a bit
4274 odd to throw an exception if a string can't be found in the
4275 environment, but it's consistent with open-file, stat etc.
4276 (simpos.h): remove sys_ from getenv.
4278 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4279 occurs, throw an error instead of returning errno. Return value
4281 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4283 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4285 * filesys.c (scm_stat2scm): derive file type and permissions from
4286 the stat mode and append them to the returned vector.
4287 There isn't much overhead in doing this and it avoids the need to
4288 work with S_IRUSR et al. in Scheme.
4289 Define symbols scm_sym_regular etc.
4290 (scm_init_filesys): don't intern S_IRUSR etc.
4292 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4293 and s_primitive_load_path.
4295 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4297 * error.h: don't declare error symbols. prototype for scm_misc_error.
4299 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4302 * error.c: use SCM_SYMBOL to set up error keys.
4303 scm_misc_error: new procedure.
4305 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4307 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4308 between `#!' and `!#' is ignored.
4309 (skip_scsh_block_comment): New function.
4311 * feature.c (scm_set_program_arguments): New argument, FIRST.
4312 * feature.h: Update prototype.
4313 * init.c (scm_boot_guile_1): Pass new argument to
4314 scm_set_program_arguments.
4316 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4318 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4319 (scm_boot_guile): Call scm_set_program_arguments here, later than
4320 the old initialization.
4322 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4323 initialization procedure.
4324 - Delete in, out, err arguments; there are other perfectly good
4325 ways to override these when desired.
4326 - Delete result argument; this function shouldn't ever return.
4327 - Rename init_func argument to main_func, for less confusion.
4328 - Delete boot_cmd argument; main_func is more general.
4329 -Add 'closure' argument, to help people pass data to main_func
4330 without resorting to global variables.
4331 - Abort if reentered; don't bother returning an error code.
4332 - Call scm_init_standard_ports to set up the default/current
4333 standard ports; no need to pass them to scm_start_stack.
4334 - Remove code to evaluate the boot_cmd, and start the repl; let
4335 the user do something like that in main_func if they want.
4336 - Remove code to package up a return value; main_func can do any
4338 - Call exit (0), instead of returning.
4339 (scm_start_stack): Don't initialize the I/O ports here; that's
4340 weird. Delete in, out, err arguments. Move guts to
4341 scm_init_standard_ports, scm_stdio_to_port.
4342 (scm_init_standard_ports): New function, to set up current and
4343 default standard ports.
4344 (scm_start_stack, scm_restart_stack): Make these static.
4345 * init.h (scm_boot_guile): Adjust declaration.
4346 (scm_start_stack, scm_restart_stack): Remove externally
4347 visible declarations for these.
4348 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4350 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4351 written out several times in scm_start_stack.
4352 * fports.h: New declaration for the above.
4354 * feature.c (scm_set_program_arguments): New function.
4355 * feature.h: New declaration for the above.
4357 * ports.c: Formatting tweak.
4359 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4361 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4362 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4363 for obtaining the address of a car or cdr field. Motivation:
4364 &SCM_CXR make assumptions about the internal structure of the
4367 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4368 Motivation: see SCM_CXRLOC.
4370 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4371 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4372 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4373 Motivation: Safer use. Some other macros are defined in terms of
4374 these operations. If these are defined using the SCM_SETCXR
4375 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4376 to inefficiency and an <e1> with side-effects could potentially
4377 break. Also, these particular operations are heavily utilized in
4378 the garbage collector. In unoptimized code there will be a
4381 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4382 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4383 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4384 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4385 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4386 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4387 vports.c: Cleaned up use of pairs: Don't make any special
4388 assumptions about the internal structure of selectors and
4389 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4390 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4391 (Among other things, this change makes it easier to build Guile
4392 with certain compilers which have problems with casted lvalues.)
4394 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4396 * stacks.c: Improve selection of relevant stack frames when making
4397 a stack object. Introduce one level of indirection in the stack
4398 object to make it possible to "narrow" to a certain region of the
4399 stack. This facilitates making use of more clever algorithms (not
4400 implemented) for selecting relevant frames and gives a cleaner
4401 design since selection of frames can be done independently of
4402 extraction of frames from the real stack.
4403 (scm_stack_id): Also take #t as argument which means look at
4406 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4407 Turn n_tail into an integer directly representing current number
4408 of frames in stack. Add field tail.
4410 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4412 * debug.c (scm_make_memoized): Made it available at scheme level.
4413 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4414 SCM_NIMP before applying heavier predicates in argument checking.
4415 (scm_local_eval): Also take memoized object as argument.
4417 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4418 aren't created with zero length, but should such a strange
4419 creature suddenly turn up...
4421 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4423 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4424 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4426 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4428 * variable.c (scm_make_variable): Make the name hint optional, as
4430 (anonymous_variable_sym): Renamed from variable_sym. All uses
4433 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4434 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4435 of scm_primitive_load_path was also changed to
4436 "primitive-load-path", from "%try-load-path". Callers changed.
4437 We'd like to respect the convention that a function named
4438 "try-mumble" should behave just like the function called "mumble",
4439 but return #f instead of signalling some error.
4440 * load.h: Rename prototypes.
4442 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4444 * print.c (make_print_state, grow_print_state), print.h: Modified
4445 the print state representation: Don't use a tail array for
4446 recording of circular references. Resizing of the print state
4447 structure invalidates the print state pointer. To avoid passing
4448 around an indirect print state reference to all printing
4449 functions, we instead let the print state reference a resizable
4452 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4454 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4455 Don't crash when passed an improper list terminated by a
4456 non-immediate value.
4458 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4460 Allocate data for structures on an eight-byte boundary, as
4461 required by the tagging system.
4462 * struct.c (alloc_struct): New function.
4463 (scm_make_struct, scm_make_vtable_vtable): Call it.
4464 * struct.h (scm_struct_n_extra_words): Bump to 3.
4465 (scm_struct_i_ptr): New "field".
4466 * gc.c (scm_gc_sweep): When we need to free the data, use the
4467 information stored by alloc_struct to find the beginning of the
4468 block allocated to the structure, so we can free it.
4470 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4472 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4475 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4476 (scm_debug_info): New member: id.
4478 * stacks.c: Stacks are now represented as structs; Stacks have an
4479 id given to them by `start-stack'.
4480 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4482 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4483 Changed stack representation.
4485 * debug.c (scm_procedure_name): Try procedure property `name' for
4486 compiled closures aswell.
4488 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4490 * eval.c: scm_i_name moved to gsubr.c
4491 (scm_m_define): Record names of all kinds of procedure
4492 objects. (Earlier, only closures were recorded.)
4494 * procprop.h: Added declaration of scm_i_name.
4496 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4497 (scm_make_gsubr): Record names of compiled closures.
4499 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4501 * debug.c, debug.h: Removed obsolete code.
4503 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4504 stacks.c: Renamed regs --> scm_contregs.
4506 * print.c (scm_free_print_state): Cleanup print state before
4507 returning it to pool. It is better to do it here than in
4508 scm_prin1 since scm_prin1 is called often.
4510 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4511 s_set_source_property_x): Check that first argument is a pair or a
4514 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4515 scm_i_line, scm_i_column and scm_i_breakpoint global.
4517 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4518 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4521 * debug.h: Added debug object smob declaration and macro
4524 * configure.in: Build with backtrace.o and stacks.o if debug
4527 * Makefile.in: Added entries for new files: backtrace.c,
4528 backtrace.h, stacks.c and stacks.h.
4530 * symbols.c (scm_sym2ovcell): Fixed documentation.
4532 * _scm.h (min, max): Added.
4534 * async.c: Moved `min' macro to _scm.h.
4536 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4537 SCM_BACKTRACE_INDENT.
4539 * eval.c: Added new debug options `maxdepth' and `indent'.
4541 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4543 * print.h: Added selector SCM_PRINT_STATE.
4545 * print.c: New functions: scm_make_print_state,
4546 scm_free_print_state.
4548 * print.h: Added declarations for scm_make_print_state,
4549 scm_free_print_state.
4551 * debug.c (scm_m_start_stack): New acro.
4553 * debug.h: Small cleanup.
4555 * init.c (scm_boot_guile_1): Moved scm_init_debug below

4578 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
4579 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
4580 declare functions with prototypes. (Patch thanks to Marius
4583 More prototype-related changes from Marius Vollmer:
4584 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4585 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4586 * ports.h (ptobfuns): Added prototypes. This means some casting in
4588 * fports.c: Added casts for initializations, since the functions
4589 are defined to take FILE * as their stream argument, not SCM.
4590 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4591 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4592 to `char *str_data' to conform to prototype.
4594 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4596 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4598 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4600 * stime.c, stime.h: use SCM_P method.
4602 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4604 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4605 be given at least two arguments. Insist that lst's last element
4606 be a list, but don't make any requirements of its predecessors.
4608 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4610 * eval.c (scm_nconc2last): Revert last change; there seems to be
4611 other stuff going on here.
4613 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4615 * eval.c (scm_nconc2last): Make sure that each element of lst
4616 (which is a list of argument lists, except for the tail) is a
4617 proper list, i.e., finite and terminated by '().
4619 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4621 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4624 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4625 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4628 * vectors.c (scm_make_vector): Fill vectors with the undefined
4629 value, to help make Guile Scheme code more portable to other
4632 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4633 * symbols.h, tags.h: Doc fixes.
4635 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4637 * async.c (scm_take_signal): Doc fixes.
4639 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4641 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4642 want to subtract it from the modulus; we just want to leave it
4645 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4647 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4650 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4652 * throw.c (scm_catch_apply): Finished implementation of
4655 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4657 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4659 (scm_init_filesys): set "i/o-extensions" feature.
4662 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4664 * Makefile.in (root.o): Correct dependencies.
4666 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4668 * Makefile.in: Added dependency entry for root.o.
4670 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4671 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4673 * init.c (scm_start_stack): Set initial root continuation number
4676 * procs.c: New function: scm_thunk_p.
4678 * procs.h: Added declarations of scm_thunk_p.
4680 * root.c: Renamed `call-with-new-root' -->
4681 `call-with-dynamic-root'.
4682 (cwdr): Removed allocation of new root state. This should be done
4683 separately by use of scm_make_root.
4684 (scm_apply_with_dynamic_root): New function: Does what it
4685 sounds like. Needed when spawning threads.
4687 * root.h: Added member last_debug_frame to root state.
4688 Added #include "libguile/debug.h"
4690 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4691 arguments. The motivation is that code in root.c needs catch
4692 functionality, and we want to avoid code duplication.
4693 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4694 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4695 handlers that run without popping the stack into the dynwind
4698 * throw.h: Added prototypes for scm_catch_apply and
4701 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4703 * root.h (scm_root, scm_set_root): Decouple thread support details
4704 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4705 SCM_SET_THREAD_LOCAL_DATA.
4707 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4708 and tortoise scanning loop.
4710 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4712 * Makefile.in: Rebuild dependencies.
4714 * libguile.h: #include "libguile/print.h" before "smob.h", since
4715 the latter uses the print_state structure.
4717 * throw.c (scm_ithrow): Use the correct variable when checking to
4718 see if a given element of scm_dynwinds is a valid catch.
4720 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4721 structure, abort; don't just silently ignore the garbage.
4723 * _scm.h: #include "print.h" here, since it seems to be used just
4725 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4726 strports.c, unif.h: Don't #include "print.h".
4728 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4730 * feature.h (scm_loc_features): Removed external declaration.
4731 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4733 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4735 * feature.c (scm_init_feature): Added threads feature (needs to be
4736 initialized here, since features doesn't exist when
4737 scm_init_threads is called).
4739 * libguile.h: Added #include "libguile/../threads/threads.h".
4740 (This is a kludge to get thread support working. This should be
4743 * configure.in, acconfig.h: Added flags for thread support.
4745 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4748 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4749 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4752 * _scm.h: Added conditional #include "threads.h"
4754 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4755 SCM_THREADS_SWITCHING_CODE.
4757 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4758 allocate the basic dynamic root object.
4759 (scm_boot_guile): Added call to scm_init_root.
4761 * root.c, root.h: Added root smob.
4762 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4763 functions: Implements dynamic roots mostly according to spec in
4764 SCM manual. Main difference is that the second argument is a
4765 throw handler rather than an error "thunk".
4767 * root.h: Added declaration of scm_init_root.
4769 * root.c: Added #include "genio.h", #include "smob.h", #include
4770 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4772 (scm_init_root): Added #include "root.x".
4774 * throw.c: Added #include "stackchk.h"
4775 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4776 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4777 can be used in scm_call_with_new_root; Added reenabling of stack
4778 checking when catching a throw.
4780 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4782 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4784 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4785 element is not found, as per R4RS.
4787 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4789 * list.c: Doc fixes throughout.
4791 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4793 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4794 declare the char * to be const. Avoids a warning in rgx.c.
4796 * ports.h: spelling fix.
4798 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4801 * load.c (scm_sys_try_load_path): throw an error if file not found
4802 (like it says it in NEWS).
4804 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4806 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4807 PROPS slot to '(), not #f; it's an empty alist.
4809 * throw.h, throw.c: Use SCM_P instead of #if hair.
4811 Remove special support for uncaught throws; see throw.c for
4813 * throw.c (uncaught_throw): New function.
4814 (scm_ithrow): Call uncaught_throw if we don't find a throw
4815 target; don't mess with scm_bad_throw_vcell.
4816 (scm_bad_throw_vcell): Variable deleted.
4817 (scm_init_throw): Don't initialize it.
4819 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4822 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4824 * numbers.c (scm_istr2int): If the number is short (as most
4825 numbers are), just call scm_small_istr2int to deal with it.
4826 (scm_small_istr2int): New function, created by un-#ifdefing the
4827 non-bignum version of scm_istr2int and renaming it.
4829 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4831 * load.c (scm_sys_try_load): don't check whether value returned
4832 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4833 Change the Scheme name from %try-load to primitive-load.
4835 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4836 Can avoid passing a message, allowing it to be derived in the
4837 error handler (e.g., if we want to throw to the key both from
4840 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4842 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4843 references now have a new appearance which is more compact and
4844 also gives a clue about what the target of the reference is.
4845 By setting parameters in the print state, more fancy printing can
4846 be achieved. This is used by the (not yet commited) backtrace
4849 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4851 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4854 * print.c: Added #include "struct.h". Removed function
4857 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4858 scm_iprin1. Removed prototype for scm_prlist.
4860 * arbiters.c (prinarb),
4861 async.c (print_async),
4862 debug.c (prindebugobj, prinmemoized),
4863 eval.c (prinprom, prinmacro),
4864 filesys.c (scm_fd_print, scm_dir_print),
4866 mallocs.c (prinmalloc),
4867 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4868 smob.h (scm_smobfuns),
4869 srcprop.c (prinsrcprops),
4871 unif.c, unif.h (scm_raprin1, rapr1),
4872 variable.c (prin_var): Changed argument `int writing' to
4873 `scm_print_state *pstate'.
4875 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4876 that it will be called before scm_init_print.
4878 * print.c (scm_prin1): Print states are now allocated when calling
4879 scm_prin1 and then passed around to all printing functions as an
4880 argument. A cache `print_state_pool' enables reuse of print
4882 (scm_make_print_state): New function.
4883 (scm_iprin1): Adaption to print states.
4884 (scm_iprlist): An initial "hare and tortoise" scan brings down
4885 time complexity to O (depth * N). (Better time complexity will be
4886 achieved when the printing code is completely rewritten.)
4888 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4890 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4891 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4892 it gets done whether or not the cache variable has a value.
4894 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4896 Distinguish #f and ().
4897 * __scm.h: #undef SICP.
4898 * pairs.h (SCM_EOL): Delete this definition, equating it with
4900 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4901 the value it used to have. Doc fixes, too.
4903 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4905 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4906 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4907 Lord's implementation of structs, allowing for tail arrays as
4908 described in the manual. Also fixed some bugs. (Both the interface
4909 and the implementation should be improved.)
4911 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4913 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4914 People who whish to see the source can do `(print-enable 'source)'.
4915 Removed #ifdef DEBUG_EXTENSIONS.
4917 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4919 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4920 integer (assuming for now accepting an integer is a good thing).
4922 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4923 %S will be used instead for write'ing arguments.
4925 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4926 asserts. fix a few other asserts.
4927 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4928 scm_uniform_vector_ref, scm_array_set_x,
4929 scm_dimensions_to_unform_array): change args in
4930 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4931 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4932 scm_substring_fill_x): likewise.
4933 gsubr.c (scm_gsubr_apply): likewise.
4934 eval.c (SCM_APPLY): likewise.
4936 * eval.c (4 places): replace scm_everr with lgh_error or
4939 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4940 scm_memory_error): new procedures.
4941 scm_everr: deleted. can use scm_wta, dropping first two args.
4942 scm_error: convert NULL subr to SCM_BOOL_F.
4944 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4947 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4950 * error.c, error.h: new error keys: scm_arg_type_key,
4951 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4953 scm_wta: reimplement using lgh_error instead of scm_everr.
4955 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4957 * gdbint.c: scm_lread now has one more argument.
4959 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4960 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4961 loading source from non-file ports, which, e. g., happens when
4962 using the Emacs interface).
4964 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4967 * read.c: Added code for recording of positions of source code
4968 expressions; New functions: recsexpr, scm_lreadrecparen;
4969 _scm_make_srcprops --> scm_make_srcprops
4970 (scm_flush_ws): Removed updating of positions counters. This work
4971 is already done by scm_gen_getc
4973 * read.h: Added prototype for scm_lreadrecparen
4975 * print.c: Added #include "alist.h"
4977 * eval.c: Added #include "hash.h"
4979 * eq.c: Added #include "ramap.h"
4981 * options.c: Documentation fixes.
4983 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
4984 (scm_init_srcprop): Adjusted size of initial source-whash. Name
4985 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
4986 --> scm_make_srcprops
4988 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
4989 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
4990 function calls in the definition of the whash access macros.
4992 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
4994 * init.c (scm_boot_guile): Add level of indirection to
4995 scm_boot_guile_1() to ensure that stack base pointer is properly
4996 initialized. There was no guarantee that variable i was the
4997 highest/lowest variable on stack (i.e. the call frame of
4998 scm_boot_guile was not completely protected from gc).
5000 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
5002 * ports.h (scm_port_table): put back file_name, it will be used to
5003 support debugging. Undo related changes in fports.c, ioext.c,
5006 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5008 * ports.h (scm_port_table): remove file_name member for now, it seems
5010 * fports.c (scm_open_file): don't set file_name in PTAB.
5011 (prinfport): don't use file_name in PTAB.
5012 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
5013 * ports.c (scm_add_to_port_table): don't intialize file_name.
5014 (scm_port_file_name): remove for now.
5015 * gc.c (scm_gc_mark): don't mark PTAB file_name.
5017 * fports.h (scm_mkfile): prototype deleted.
5018 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
5020 * debug.c, unif.c: use scm_out_of_range instead of
5021 wta for range errors (ASSERT still needs work).
5023 * error.c, error.h (scm_out_of_range): new procedure.
5025 * error.c, error.h (scm_out_of_range_key): new key.
5027 * posix.c (scm_sync): #else was missing.
5029 * error.c, error.h: append _key to names scm_num_overflow and
5032 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
5033 of consing an empty list.
5034 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
5035 of macros, saves code and string space.
5036 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
5037 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
5038 lower case. Rename scm_syserror_m to scm_syserror_msg.
5039 error.h: prototypes for new procedures.
5041 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
5043 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
5045 * error.c, error.h: setup scm_num_overflow key.
5047 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
5048 Remove definition of SCM_OVSCM_FLOW.
5050 * fports.c (scm_open_file): use SCM_SYSERROR_M.
5052 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
5053 explicit message and args.
5055 * error.c, error.h, __scm.h: change system_error_sym to
5058 * error.c (system_error_sym): remove leading %% from the Scheme name
5061 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
5063 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5065 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
5066 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
5067 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
5068 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
5069 renamed. (These were introduced by unsupervised name
5072 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5074 * print.c: Added code for detection of circular references during
5075 printing. (init_ref_stack, grow_ref_stack): New functions. Added
5076 a hook for printing of closures (accessible via print options).
5077 This leads to a split of calls to scm_iprin1 into two classes:
5078 elementary print operations (e. g. the code which prints a smob)
5079 still use scm_iprin1 while top level calls (like scm_display) use
5080 scm_prin1. scm_prin1 begins by clearing the data structure used
5081 to record reference information.
5083 * print.h: Added declarations of scm_prin1 and scm_prlist.
5085 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
5087 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
5089 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
5091 * error.c (err_head): scm_iprin1 --> scm_prin1
5093 * debug.c: Adjusted header comment.
5097 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
5099 * strerror.c: Doc fix.
5101 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5103 * gdbint.c (gdb_read): Now possible to run during GC.
5104 (unmark_port, remark_port): New functions.
5106 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
5108 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
5109 of allocating a new string object. Also, increase size by
5110 the factor 2 instead of 1.5.
5112 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
5114 * __scm.h (SCM_P): Corrected to run under traditional C.
5116 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
5119 * async.c: Calls to scm_sysintern corrected.
5121 * async.h (scm_async_clock): Redundant declaration removed.
5123 * continuations.c (scm_dynthrow): Redundant declaration removed.
5125 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
5126 Definition typos corrected.
5128 * debug.h: Missing declarations of functions in debug.c added
5131 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
5132 Missing declarations to functions in eval.c added.
5134 * filesys.c: Possibly uninitialized variable rv.
5136 * gc.h (scm_object_addr, scm_unhash_name): Missing
5137 declarations of functions defined in gc.c added.
5139 * genio.c: Possible typos str_data -> wstr_data. ???
5141 * genio.c: Possibly unintended shadowing of local variable
5142 `int c' (gotos out of scope of inner `c'). ???
5144 * init.c: Uninitialized `SCM last' may be used.
5146 * ioext.h: (scm_sys_isatty_p): Typo.
5148 * list.h (scm_list_head): Missing prototype for function in
5151 * numbers.c (scm_two_doubles): Changed from extern to static
5152 (is used only within numbers.c).
5154 * numbers.h: Repeated declarations removed.
5156 * ports.h (scm_close_all_ports_except): Declaration for the
5157 function defined in ports.c added.
5159 * posix.h: Missing declarations added.
5161 * procs.h (scm_make_subr_opt): Missing declaration added.
5163 * socket.h (scm_sys_gethost): Missing declaration added.
5165 * socket.h: Redundant declarations removed (they are in fdsocket.h).
5167 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
5168 Missing declarations added.
5170 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
5172 * struct.c: Uninitialized variable `SCM answer' may be used.
5174 * unif.c (l2ra): Declaration prototype.
5176 * unif.c (scm_array_equal_p): Dummy definition removed (it is
5177 defined in ramap.c).
5179 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
5180 Redundant declarations removed (they are in ramap.h).
5182 * variable.h (scm_make_udvariable,
5183 scm_make_undefined_variable): Declaration corrected to
5184 correspond variable.c.
5186 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
5187 Missing declarations added.
5189 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5191 * Makefile.in (distclean): Don't forget to delete fd.h.
5193 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5195 * fd.h.in, tags.h: Trivial cleanups.
5197 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5198 marksweep.h just declared functions from gc.c.
5199 * gc.h, libguile.h: Don't #include "marksweep.h".
5200 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5201 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5202 dependencies updated.
5204 * libguile.h: Don't #include "files.h"; it's been deleted.
5206 * files.c (scm_sys_delete_file): Moved to filesys.c.
5207 File is now empty; deleted.
5209 * filesys.c: scm_sys_delete_file is now here. Remove
5210 #if's; they seem to rely on remnants of an old portability
5211 regimen. If the problems come up again, solve them properly,
5212 using autoconf. Specifically: Don't test M_SYSV, and #define
5213 remove to be unlink if it's #defined; don't use remove just
5214 because HAVE_STDC_HEADERS is #defined.
5215 * filesys.h: Add declarations for scm_sys_delete_file.
5216 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5217 files.o, files.h, files.c, and files.x.
5218 * init.c: Don't #include "files.h", and don't call scm_init_files.
5220 Use SCM_P instead of PROTO; the latter intrudes on the user's
5222 * params.h: Deleted; definition of SCM_P moved to...
5223 * __scm.h: ... here, where it replaces PROTO macro.
5224 * libguile.h, smob.h: Don't #include "params.h".
5225 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5226 smob.h: Fix prototypes accordingly.
5227 * Makefile.in: Update dependencies.
5228 (inner_h_files): Remove params.h.
5230 * gc.c: #include "gc.h"; every module should include its header,
5231 to let the compiler cross-check the declarations against the
5234 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5235 simpos.h: #include "libguile/__scm.h".
5237 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5239 * init.c: Don't forget to #include smob.h and init.h.
5240 * Makefile.in: Dependencies updated.
5242 * smob.h: Use PROTO instead of #if __STDC__.
5244 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5246 * __scm.h: Doc fixes.
5248 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5249 <angles>; this allows `make depends' to work properly.
5251 * libguile.h: #include smob.h and pairs.h before the others; they
5252 define typedefs used by other headers.
5254 C files should #include only the header files they need, not
5255 libguile.h (which #includes all the header files); the pointless
5256 recompilation was wasting my time.
5257 * Makefile.in (all .o dependency lists): Regenerated.
5258 * libguile.h: Don't try to get a definition for size_t here...
5259 * __scm.h: Do it here.
5260 * _scm.h: Since this is the internal libguile header, put things
5261 here that all (or a majority) of the libguile files will want.
5262 Don't #include <libguile.h> here; that generates dependencies on
5263 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5264 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5265 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and
5267 * alist.c: Get "eq.h", "list.h", "alist.h".

5281 * error.c: Get "error.h", "throw.h", "genio.h", "pairs.h".

5366 * print.h, read.h: #include "options.h", since everyone who uses
5367 either of these files will need that.
5369 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5370 anyone who uses this file will need them to define the smob
5371 printing functions. Also, get markers.h, since people will need
5372 to #define the mark functions.
5374 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5375 * ports.h: ... to here.
5377 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5378 don't rely on archaic C default type rules.
5380 * fports.h: #include "libguile/ports.h", since you need that in
5381 order to parse this.
5383 * genio.h: #include "libguile/print.h", because you need that to
5384 parse this; don't bother #including "ports.h", since print.h gets
5387 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5389 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5390 this; it's now a reference to an element of *scm_root.
5392 * debug.h: Don't #include "options.h"; the compiler won't be able
5393 to find that once the headers are installed; instead, #include
5394 "libguile/options.h".
5395 * gc.h: Same, with marksweep.h.

5397 * scmhob.h: Same, with _scm.h.
5398 * smob.h: Same, with params.h.
5400 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5401 C files; there's no need for this, and it forces recompilations
5404 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5406 * error.c (scm_error): declare scm_error_callback.
5408 * error.h: prototype for scm_error_callback.
5410 * __scm.h: define lgh_error.
5411 (SCM_SYSERROR): redefine using lgh_error.
5413 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5415 * error.c (scm_error): new procedure.
5417 * error.h: prototype for scm_error.
5419 * Makefile.in (install): install scmconfig.h from the current
5420 directory, not $(srcdir).
5422 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5424 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5425 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5426 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

5432 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5433 vports.h, weaks.h: #include "libguile/__scm.h", not
5434 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5435 dependencies are within libguile properly.
5437 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5439 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5440 when scmconfig.h doesn't exist.
5442 * load.c (scm_sys_try_load): Correct spelling.
5444 * feature.c (scm_loc_features): Make this static.
5446 * Makefile.in (libpath.h): Omit trailing slash from path. We
5447 shouldn't require it of users, so why put it here?
5449 Move code to initialize and search %load-path from ice-9 to C
5450 code, so we can use the load-path to find the ice-9 boot code;
5451 this makes it easier to run Guile without installing it. See
5452 corresponding changes in guile/Makefile.in.
5453 * feature.c: Move stuff concerned with the load path to load.c.
5454 (scm_compiled_library_path): Deleted.
5455 Don't #include libpath.h here.
5456 * feature.h: Don't mention scm_compiled_library_path.
5457 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5458 <sys/stat.h>, and <unistd.h> (if present).
5459 (R_OK): #define if the system hasn't deigned to.
5460 (scm_loc_load_path): New variable.
5461 (scm_init_load_path, scm_sys_search_load_path,
5462 scm_sys_try_load_path): New functions.
5463 (scm_init_load): Initialize scm_loc_load_path to point to the
5464 value cell of the Scheme %load-path variable.
5465 * load.h: Add declarations for scm_sys_search_load_path,
5466 scm_sys_try_load_path.
5467 * init.c: Call scm_init_load_path.
5468 * Makefile.in (feature.o, load.o): Dependencies updated.
5470 * load.c, load.h: Rewrite using PROTO macro.
5472 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5474 * gc.c (scm_cellp): New function: C predicate to determine if an
5475 SCM value can be regarded as a pointer to a cell on the heap.
5477 * gc.h: Added declaration of scm_cellp.
5479 * gdb_interface.h: New file: The GDB interface header from the GDB
5482 * gdbint.c: New file: GDB interface.
5484 * gdbint.h: New file: GDB interface.
5486 * libguile.h: Added #include <libguile/gdbint.h>.
5488 * init.c (scm_boot_guile): Added scm_init_gdbint.
5490 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5491 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5492 found if object files and source are kept separate).
5494 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5496 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5498 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5500 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5501 TK_SRC_DIR; they're not relevant any more.
5503 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5504 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5506 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5508 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5509 search path, so we can find the <libguile/MUMBLE.h> headers.
5511 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5513 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5514 implicit in the .c.o rule.
5515 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5518 Put the library path in a header file, instead of passing it on
5519 the command line in every compilation.
5520 * Makefile.in (libpath.h): New target.
5521 (feature.o): Depend on libpath.h.
5522 (clean): Delete libpath.h.
5523 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5524 * feature.c: ... #include "libpath.h" here.
5525 * .cvsignore: Ignore libpath.h.
5527 Don't install the unwashed masses of Guile header files in the
5528 main #include path; put most of them in a subdirectory called
5529 'libguile'. This avoids naming conflicts between Guile header
5530 files and system header files (of which there were a few).
5531 * Makefile.in (pkgincludedir): Deleted.
5532 (innerincludedir): New variable; this and $(includedir) are enough.
5533 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5534 (installed_h_files): Divide this up. Now this variable lists
5535 those header files which should go into $(includedir) (i.e. appear
5536 directly in the #include path), and ...
5537 (inner_h_files): ... this new variable says which files appear in
5538 a subdirectory, and are referred to as <libguile/mumble.h>.
5539 (h_files): List them both.
5540 (install): Create innerincludedir, not pkgincludedir. Put
5541 the installed_h_files and inner_h_files in their proper places.
5542 (uninstall): Corresponding changes.
5543 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5544 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5545 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5546 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5547 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5548 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5549 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5550 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5551 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5552 vports.h, weaks.h: Find __scm.h in its new location.
5553 * __scm.h: Find scmconfig.h and tags.h in their new locations
5554 (they're both "inner" files).
5556 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5558 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5560 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5562 * posix.c: Doc fixes.
5564 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5566 * socket.c: Don't include a prototype for inet_aton; just use a
5567 K&R style declaration, to avoid warnings but minimize the chance
5568 of conflicts with the system.
5570 On NextStep, <utime.h> doesn't define struct utime, unless we
5571 #define _POSIX_SOURCE before #including it.
5572 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5573 * acconfig.h: New comment text for above CPP symbol.
5574 * configure.in: Call it.
5575 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5577 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5579 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5580 testing for __EMX__.
5582 * posix.c: #include <libc.h>, if it exists.
5584 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5585 don't even know if the latter exists.
5587 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5588 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5589 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5591 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5593 (scm_init_posix): Use them when initializing the Scheme constants
5596 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5598 * Makefile.in (libdir, includedir, bindir): Use the
5599 autoconf-supplied values, instead of deriving them ourselves.
5600 (pkgincludedir, datadir, pkgdatadir): New variables.
5601 (install, uninstall): Put the header files in a special
5602 subdirectory, not in the main search path.
5604 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5605 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5607 * Makefile.in (IMPLPATH): Deleted; never used.
5609 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5610 on the Tcl/Tk source any more.
5611 (INCLUDE_CFLAGS): Remove references to the above.
5613 * Makefile.in (version.o): Corrected dependencies.
5615 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5617 * libguile.h: #include "version.h"
5619 * init.c (scm_boot_guile): Call scm_init_version.
5620 * gscm.c (gscm_run_scm): Call scm_init_version.
5622 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5623 GUILE_VERSION): AC_DEFINE these.
5624 (acconfig.h): #undef the above symbols.
5626 * Makefile.in (libobjs): Add version.o.
5627 (installed_h_files): Add version.h.
5628 (c_files): Add version.c.
5629 (gen_c_files): Add version.x.
5630 (version.o): New rule.
5631 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5632 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

5641 weaks.o): Add version.h to dependency lists.
5642 (markers.o): Remove duplicate rule.
5644 * version.h: New file.
5646 * version.c: New file.
5648 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5650 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5651 array; use it appropriately. Since GCC is quite happy to
5652 subscript functions, it never warned us about this; we should use
5653 -Wpointer-arith in the future. I guess we never tested
5656 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5658 * socket.c: Doc and copyright fixes.
5660 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5662 * debug.c: Fixed and improved gdb support.
5664 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5666 * socket.c: Added declaration of inet_aton to avoid compiler
5667 warning. (Hope this solution is correct.)
5669 * stime.c: Added declaration of ftime. (This is missing in
5672 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5674 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5676 * Makefile.in (c_files): add strerror.c.
5678 * strerror.c: new file from Emacs' sysdep.c.
5679 maybe configure should also check for sys_errlist.
5681 * configure.in (AC_REPLACE_FUNCS): add strerror.
5683 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5685 * debug.c (scm_init_debug): Added initialization for
5686 scm_evaluator_traps.
5688 * debug.h, debug.c: Various name changes.
5689 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5690 "debug-options-interface". See commentary in options.c.
5692 * options.h, options.c: Options now have documentation strings.
5693 Also added a long explanatory commentary.
5695 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5698 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5699 last_debug_info_frame is now updated in all cases.
5701 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5704 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5706 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5707 Added option STACK_CHECKING.
5709 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5711 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5713 * __scm.h: Removed symbols for debugging support.
5715 * acconfig.h: Added symbols for debugging support.
5717 * configure.in: Added user option for debugging support.
5718 --enable-debug will include the debugging code into libguile.a.
5720 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5721 scm_relocate_chunk_to_heap.
5723 * debug.c: New file: low-level debugging support. It also
5724 includes support for debugging with gdb. (The extensions to gdb
5725 are written by Per Bothner at Cygnus.)
5727 * debug.h: New file: low-level debugging support.
5729 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5730 argument pairs. Extensive modifications to the debugging
5731 evaluator. Added "SECTION:" commentaries to clarify what happens
5732 when, during double compilation. Renamed EVALIMP --> EVALIM.
5733 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5734 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5735 the beginning of the file. New procedure: scm_unmemocopy.
5736 Added some global state variables needed by the debugging
5737 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5738 check_entry, check_apply, check_exit, debug_options and
5739 evaluator_traps. New acro: undefine.
5741 * eval.h: Renamed EVAL --> XEVAL.
5743 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5744 --> scm_make_weak_key_hash_table.
5746 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5747 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5749 * libguile.h: Conditionally include debug.h
5751 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5752 scm_object_properties shouldn't return handle. `handle' now gets
5753 initialized in scm_set_object_properties_x. scm_object_properties
5754 doesn't any longer create an entry in scm_object_whash.
5756 * options.c: New file: handling of run time options.
5758 * options.h: New file: handling of run time options.
5760 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5762 * print.c: New procedure: scm_print_options
5764 * print.h: Defines for print options.
5766 * read.c: New procedure: scm_read_options
5768 * read.h: Defines for reader options.
5770 * root.h: Added scm_source_whash among scm_sys_protects.
5772 * srcprop.c: New file: source properties.
5774 * srcprop.h: New file: source properties.
5776 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5777 (Bug found by A. Green.)
5779 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5781 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5783 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5785 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5787 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5788 and should be called by the final client.
5790 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5792 * gc.h: Use the PROTO macro when declaring functions.
5793 * gc.c: Use the PROTO macro when declaring static functions.
5794 Remove the CPP hair around function definitions.
5796 * gc.c (scm_init_storage): Initialize scm_asyncs.
5798 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5799 preprocessor symbol; "__scm.h" is where it might get #defined.
5800 * __scm.h: Similar: #include <scmconfig.h> before testing
5803 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5805 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5807 * init.c (scm_boot_guile): Add init_func argument; call
5808 (*init_func) instead of calling scm_appinit; it's ucky to
5809 hard-code names for the user's procedures.
5810 * init.h (scm_boot_guile): Adjust declaration.
5812 * __scm.h (PROTO): New macro, for declaring functions with
5815 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5816 eliminate all the __STDC__ conditionals.
5817 (scm_boot_guile): Add declaration.
5818 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5819 Remove __STDC__ conditionals around function definitions; the
5820 declarations in init.h will provide the same information, more
5823 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5824 complain about it in the error message; the error message is
5825 adequate without that note, and there's nothing the user can do
5828 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5830 * Makefile.in (ancillary): Drop def.sed.
5832 * posix.c (scm_init_posix): Use numeric values, rather than
5833 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5834 F_OK. The symbols aren't available on some systems, and I'm
5835 pretty sure their values are fixed by common widespread practice.
5836 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5838 More functions unavailable on some systems.
5839 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5840 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5842 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5843 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5844 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5845 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5846 stub that signals an error as the #else.
5848 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
5850 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
5852 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
5854 * unif.c: include ramap.h.
5856 * read.c (endif): case_insensative_p renamed case_insensitive_p.

5860 * ports.c: include sys/ioctl.h.
5862 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
5864 * configure.in: check for sys/ioctl.h.
5866 * ports.c: include <malloc.h> not "malloc.h".
5868 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5870 * fports.c: remove ttyname and tmpnam declarations.
5872 * posix.c: fewer ttyname declarations.
5874 * fports.c: include <string.h> not "string.h".
5876 * init.c, ioext.c: include string.h and unistd.h.
5878 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5880 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
5881 genio.c, simpos.c, vports.c: include string.h.
5883 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
5885 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
5887 (scm_addr_buffer_size): change type from scm_sizet to int.
5888 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
5889 from scm_sizet to int.
5891 * error.c: include unistd.h.
5893 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
5896 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
5898 * __scm.hd, def.sed: deleted.
5900 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
5902 Changes for NeXT, suggested by Robert Brown.
5903 * configure.in: Call AC_TYPE_MODE_T.
5904 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
5905 NeXT. Put header file list in alphabetical order.
5906 * configure, scmconfig.h.in: Regenerated.
5907 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
5909 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
5912 * acconfig.h: New file, providing documentation for the CPP
5913 symbols defined in configure.in
5914 * acconfig-1.5.h: Removed; superceded by the above.
5916 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
5918 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
5920 * fports.c (scm_open_file): don't return #f, throw error.
5922 * ioext.c (fileno): renamed from %fileno.
5923 (soft-fileno): deleted.
5925 * ports.c (scm_port_revealed): don't need to check for -1 from
5927 (scm_set_port_revealed_x): return unspecified, not #f.
5929 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
5931 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
5933 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
5935 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
5937 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5939 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5940 This is necessary on Ultrix, and doesn't hurt portability.
5942 * Makefile.in (dist-dir): New target, implementing a new dist system.
5943 (installed_h_files): Put in alphabetical order.
5944 Remove duplicate entries for markers.h and unif.h.
5945 (c_files): Remove duplicate entries for markers.c.
5946 (ancillary): Renamed from anillery; all uses changed. Remove
5947 PLUGIN; it's a directory, and needs special treatment in dist-dir.
5948 Remove all the ../doc/* files; doc/Makefile.in handles that.
5950 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5952 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5953 every if must have an else, or else the whole command has a
5954 non-zero exit code whenever the if's condition is false.
5956 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
5958 * posix.c: include string.h.
5960 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
5962 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
5965 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
5966 Remove leading % from scheme names.
5967 Do not return error values, call SCM_SYSERROR or similar.
5969 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
5971 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
5973 * struct.c (scm_init_struct): new file.
5975 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
5977 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
5978 (scm_list_head): added list-head for rapidly chopping argument
5979 lists off of longer lists (and similar).
5981 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
5983 * objprop.c (scm_object_property): assq the cdr of the whash
5984 handle for obj, not the handle itself.
5986 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
5988 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
5989 weak hash tables last of all marking to avoid an obscure gc bug.
5990 WARNING: circular lists stored in a weak hash table will hose us.
5992 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
5994 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
5995 new functions similar to scm_substring_move_left_x and
5996 scm_substring_move_right_x.
5998 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
6000 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
6003 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
6005 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
6007 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
6009 * strports.c (scm_strprint_obj): convenience function. C for
6010 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
6012 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
6013 removed to a separate library
6015 * init.c (scm_boot_guile): copied from guile-tcl.c.
6016 Initialization specific to tcl interpreters removed.
6018 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
6020 * ports.c (scm_ports_prehistory): size malloced here doesn't
6021 matter so long as it is non-0 (got rid of "* 4").
6023 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
6025 * gscm.h: gscm_mkarray eliminated (presumably was not being used
6026 since its definition was bogus).
6028 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
6030 * mallocs.[ch]: back again (for rx at least).
6032 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
6034 * ports.c: removed functions relating to the mapping between ports
6035 and descriptors. (That stuff is unix-specific and should be collected
6036 in a separate library).
6038 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
6039 (Tom Mckay@avanticorp.com)
6041 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
6043 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
6044 handled correctly (SCM_FREEP was applied to them) -- test for
6045 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
6046 being overwritten with #f. (brown@grettir.bibliotech.com)
6048 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
6050 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs

6053 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
6055 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak

6060 * list.c (scm_last_pair): map '()=>'()
6062 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>

6065 Generalized assoc and hash-table functions.
6066 Factored pairs.c into multiple files.
6068 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
6070 * gscm.c (gscm_run_scm): got rid of objprop.
6072 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
6074 * genio.c (scm_getc):
6075 NOTE: fgetc may not be interruptable.
6077 * procprop.c (scm_stand_in_scm_proc):
6078 NOTE: don't use a alist here.
6079 (scm_set_procedure_properties_x): fix type checking throughout this file.
6081 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
6083 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
6084 after freeing part of the port table.

6088 * strports.c (scm_mkstrport):
6089 * vports.c (scm_make_soft_port): allocate a port table entry
6090 (possibly triggering gc) before setting the tag of the corresponding
6093 * pairs.c (scm_delq_x): never throw an error.
6095 * vectors.c (scm_make_vector): made the default vector fill argument
6096 into '() (much more useful than the previous value, "#unspecified")
6098 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
6100 * ports.c (scm_add_to_port_table): Added fields
6101 to port table entries: file_name, line_num, col.
6102 Update these in open_file, gen_getc and gen_ungetc.
6103 Added procedures to access those fields.
6105 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
6107 * procs.c (scm_make_subr_opt): new entry point for making
6110 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
6112 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
6114 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
6116 * numbers.c (scm_exact_p): This function no longer
6117 implements "integer?".

6121 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
6122 (scm_gc_stats): return an assoc of useful data. Replaces "room"
6123 and the stats reporting formerlly built into repl.

6126 GC statistics keeping moved to gc.c.
6127 Other statistics keeping can be done from Scheme.
6128 REPLS are now written in Scheme.

6135 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
6137 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
6139 * feature.c (scm_compiled_library_path): moved here from repl.c.
6140 This file is for stuff relating specifically to Scheme libraries
6143 * eval.c (scm_m_define): don't give warning about redefinition, don't
6146 NOTE: this should throw a resumable exception with parameters --
6147 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
6149 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
6151 * error.c: scm_warn eliminated.

6163 between the call to procedurep and use.
6165 * error.c (scm_everr):
6167 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
6170 * strports.c: don't reveal the port's string to the caller
6171 because it changes size.
6173 (stputc stwrite): check/change the strings length with interrupts
6176 * objprop.c (scm_set_object_property_x &c): use the generic
6177 hashing functions and be threadsafe.
6179 * eval.c (scm_unmemocar): do this operation in a thread-safe way.
6180 (per suggestion jaffer@gnu.ai.mit.edu).
6182 * mbstrings.c (scm_multi_byte_string): guard against argument list
6185 * strings.c (scm_make_string): loop cleanup
6187 * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer
6190 * weaks.c (scm_weak_vector): guard against argument list
6193 * variable.c (scm_builtin_variable): check for/make a built-in
6196 * vectors.c (scm_vector): while filling the new array,
6197 guard against a list of fill elements that grows after
6198 the vector is allocated.
6200 * hashtab.c -- new file: general hash table
6201 functions. hash, hashq, hashv, hashx.
6203 * tags.h: made wvect an option bit of vector.

6207 * symbols.c: made the basic symbol table operations atomic.
6209 * root.c &c.: collected stack-specific global state.
6210 linum/colnum etc *should* be port-specific state.
6212 * struct.c (scm_init_struct): init the first struct type during
6213 initialization to fix a race condition.
6215 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
6216 object, not in a global.
6217 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
6219 * throw.c (_scm_throw): Pass throwval on the stack, not in a global
6220 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
6222 * *.[ch]: namespace cleanup. Changed all (nearly) exported CPP
6223 and C symbols to begin with SCM_ or scm_.

6234 * async.c: New support for interrupt handlers.
6236 Thu Feb 15 11:39:09 1996 Tom Lord <lord@beehive>
6238 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
6239 set the multi_byte flag correctly in symbols. This is wrong.
6240 intern_obbary_soft and msymbolize should take an extra parameter.
6241 Also, weird multibyte symbols don't print correctly.
6242 The weird symbol syntax is also a bit bogus (emacs doesn't quite
6245 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
6247 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means
6248 use the system symhash. == #t means create an uninterned symbol.
6250 Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>
6252 * strings.c (scm_make_shared_substring): build'em.
6253 It might better to keep a table of these and use one
6254 less cons-pair per shared-substring.
6256 Tue Feb 6 17:45:21 1996 Tom Lord <lord@beehive>
6258 * strings.c (scm_string_shared_substring): create shared

6301 * strop.c (scm_i_rindex, scm_i_index): Don't use the BSD functions
6302 index/rindex. Do handle embedded \000 characters.
6304 Sun Jan 28 13:16:18 1996 Tom Lord <lord@beehive>
