1 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
4 don't contain interesting information since all arguments are
5 present in the frame which applies the compiled closure anyway.);
6 Skip the transformer application frames.
8 * print.c (scm_iprin1): Print gsubrs as primitives.
10 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
12 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
14 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
15 that we can identify these in a backtrace. (This change doesn't
16 introduce any significant speed penalty.)
18 * eval.c: Added note about `serial-map' using scm_map.
20 * read.c, read.h (scm_read_options, scm_read_opts): Removed
21 readline options. They should reside in their own options array.
23 * readline.c, readline.h (scm_readline_options,
24 scm_readline_opts): Moved readline options here.
26 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
28 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
29 SCM_ROCHARS instead of SCM_CHARS.
31 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
32 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
34 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
36 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
37 This is quite important since the latter clears the
38 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
39 every single character read...
41 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
43 * print.c (scm_iprin1): Removed suspect looking (and indeed
44 malevolent) semicolon after test for user supplied closure print
45 procedure. (Thanks to Telford Tendys.)
47 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
48 (scm_memq, scm_memv, scm_member): Do argument checking *before*
49 starting to search the list. Removed call to sloppy_mem_check.
51 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
52 procedures: Same as scm_delq_x et al, but delete maximally one
55 * options.c (scm_options, scm_init_options): GC-protect option
56 values of type SCM. (Thanks to Telford Tendys.)
58 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
60 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
61 make sure that there always is a "real" scm_lookupcar.
63 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
65 * read.c, read.h (history-length, history-file): New read options.
66 (scm_read_options): Stifle history to history length.
68 * readline.c (scm_read_history, scm_write_history): New
71 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
73 * eval.h (scm_macro_eval_x): Removed declaration.
75 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
76 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
77 Renamed and made global.
79 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
80 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
82 * evalext.c, evalext.h: New files. Contain non-R5RS things
83 having to do with evaluation.
85 * evalext.c (scm_serial_map): New procedure: Version of `map'
86 which guarantees that the procedure is applied to the lists in
88 (scm_m_sequence_to_list): New syntax: Version of `begin' which
89 returns a list of the results of the body forms instead of the
90 result of the last body form.
91 (scm_definedp, scm_m_undefine): Moved from eval.c
93 * evalext.h (scm_m_sequence_to_list): Added declaration.
95 * macros.c, macros.h: New files.
96 (scm_procedure_to_syntax, scm_procedure_to_macro,
97 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
98 scm_macro_name, scm_macro_transformer): Moved from eval.c
99 (scm_make_synt): Moved from eval.c
101 * procs.c, procs.h (scm_procedure_documentation): Moved from
104 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
107 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
109 * debug.c, print.c: Added #include "macros.h".
111 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
113 This change adds the ability to use `unread-char' multiple times
114 without interspersed reads and adds the new procedure
115 `unread-string'. The change is optimized for the common case of
116 unreading a single character. This is also the reason behind the
117 choice to store characters in the port itself: in most cases no
118 extra malloc is required.
120 The amount of code in some macros in ports.h has been increased to
121 the extent that they would fit better as C functions, but, since
122 this code belongs to the port representation, such functions
123 should be placed in ports.c which would cause calls back and forth
124 between ports.c and genio.c. That is not good for performance.
125 Also, keeping them as macros allows the compiler to do some
126 optimizations which are needed to make the current interface
127 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
129 One benchmark (Guile startup time) indicates an increase of
130 loading speed of 1%. Another (reading (using `read') boot-9.scm
131 10 times) shows no change in performance.
133 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
134 made to find a beautiful solution.)
136 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
137 (SCM_TRY_CLRDY): New macro: Only clear the first unread
138 character. (SCM_CLRDY clears all.)
139 (SCM_N_READY_CHARS): New macro: Returns number of unread
140 characters in a port. Returns wrong answer if SCM_CRDYP is false.
141 (struct scm_port_table): New fields: `entry' contains port table
142 index, `cp' points to last unread char, `cbuf' is the buffer for
143 unread chars, `cbufend' points after end of the character buffer.
145 * ports.h, ports.c (scm_unread_string): New procedure.
146 (scm_grow_port_cbuf): New function.
148 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
150 (scm_generic_fgets), fports.c (local_fgets): Use a loop
151 to read unread characters. Use SCM_TRY_CLRDY instead of
154 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
156 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
158 * genio.c, genio.h (scm_ungets): New function.
160 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
163 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
165 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
166 declarations. (Thanks to Russ McManus.)
168 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
170 * numbers.c (num2long): As a software archeologist, I'm proud of
171 this finding! :) Preliminary dating suggests an almost 4 year old
172 remnant from the SCM ancestor. The sample has been removed from
173 the finding site and is now safely stored in the repository.
175 * numbers.h: Removed prototype for num2long.
177 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
179 * gh_data.c (gh_scm2doubles): Make it possible to pass result
181 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
182 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
183 * gh.h: Updated and added prototypes.
185 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
187 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
189 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
191 * guile-snarf.in: Never generate an empty file. (Thanks to
194 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
195 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
196 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
197 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
198 gh_new_procedure5_0): Specify argument types, to appease C++
199 compilers. (Thanks to Brad Bowman.)
201 Bug reports from Russ McManus:
202 * guile-snarf.in: If the CPP environment variable is set, use that
203 as the C preprocessor, instead of the preprocessor autoconf
205 * snarf.h (SCM_PROC): Cast the function pointer passed to
206 scm_make_gsubr, to satisfy C++.
208 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
209 Use the handler passed, instead of ignoring it and using
210 gh_standard_handler. (Thanks to Etienne Bernard.)
212 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
214 * ports.h: Put text after #endif in comment. (Thanks to Nicolas

237 * script.c (scm_compile_shell_switches): Define
238 use-emacs-interface in the root module, so the repl code can see
239 it. See today's change to top-repl in ice-9/boot-9.scm.
241 * filesys.c (set_element, get_element): Make sure that `element'
242 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
243 Boekemeier and Jorgen "forcer" Schaefer.)
245 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
247 * chars.c (scm_charnames): In ASCII character name table, make
248 newlines print as #\newline by default, not #\nl.
250 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
251 alphabetical order. Oh thrills. But it helps me know how far
252 along in the compilation I am.
253 * Makefile.in: Regenerated.
255 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
257 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
258 #bytes(...) to #y(...), and syntax for short vectors from
259 #short(...) to #h(...). This may seem nutty, but, like the other
260 uniform vectors, byte vectors and short vectors want to have the
261 same print and read syntax (and, more basic, want to have read
262 syntax!). Changing the read syntax to use multiple characters
263 after the hash sign breaks with the conventions used in R5RS and
264 the conventions used for the other uniform vectors. It also
265 introduces complexity in the current reader, both on the C and
266 Scheme levels. (The Right solution is probably to change the
267 syntax and prototypes for uniform vectors entirely.)
269 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
271 Don't use local_fgets on sockets; ftell doesn't work on sockets.
272 (Thanks to Jorgen "forcer" Schaefer.)
273 * ports.h (SCM_NOFTELL): New flag.
274 * fports.c (local_fgets): If it's set, use the generic fgets.
275 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
277 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
279 * script.c (scm_compile_shell_switches): Add handling of -q switch
280 (inhibit loading of user init file).
281 (scm_shell_usage): Add usage text for -q switch.
282 (scm_compile_shell_switches): Always load user init file first if
285 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
287 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
288 and is now broken under NetBSD. I can't fathom what it's trying
289 to do, so I've replaced it with something that I do understand,
290 which seems to work, and which isn't broken on NetBSD. "Progress?
291 You Decide." (Thanks to Perry Metzger.)
293 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
294 signed/unsigned comparison.
296 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
298 Warning fixes from Greg Harvey:
299 * unif.c (scm_array_set_x): initializer for pos
300 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
301 * struct.c (scm_struct_ref, scm_struct_set_x): Added
302 initializers for field_type, since EGCS so desparately wants to
304 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
305 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
306 when GUILE_DEBUG is defined.
307 * dynwind.h (scm_wind_chain): Same.
308 * ports.h (scm_pt_size, scm_pt_member): Same.
309 * print.h (scm_current_pstate): Same.
310 * procs.h (scm_make_cclo): Same.
312 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
314 Handle short and long long uniform arrays properly. (Thanks to
316 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
317 raeql_1): Add cases for scm_tc7_svect (short vectors) and
318 scm_tc7_llvect (long long vectors).
320 Change the way libguile and boot-9.scm are timestamped, to try to
321 get rid of these spurious mismatch warnings. Now both
322 libguile/versiondat.h and ice-9/version.scm are generated directly
323 by the configuration process, rather than having version.scm
324 generated directly, and libguile/versiondat.h generated by the
325 Makefile, which is generated by configure. It seems that
326 sometimes the Makefile would change, but versiondat.h depends on
327 Makefile.in, not Makefile, so it wouldn't get rebuilt.
328 * Makefile.am (versiondat.h): Target removed; this is generated
329 directly by the configure script now.
330 (BUILT_SOURCES): Remove versiondat.h.
331 * versiondat.h.in: New file, transformed by the configure script
333 * Makefile.in: Regenerated.
335 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
336 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
337 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
338 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
339 if we want to use them in a header file some day, we can. (Thanks
342 * stime.c (scm_get_internal_real_time): Do the arithmetic using
343 SCM numbers, so we won't have rollover problems; the range of a
344 signed long in milliseconds is about 25 days. (Thanks to Karl
347 Don't redefine sleep and usleep; fix this problem now.
348 * coop.c (sleep, usleep): Remove declarations; we don't use or
349 redefine these any more.
350 (scm_thread_usleep, scm_thread_sleep): New functions which do the
351 job of usleep and sleep in a thread-friendly way. We can use
352 these in the rest of Guile. Define versions for systems both with
354 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
355 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
356 we're just using it, not redefining it, we can use a K&R style
358 (sleep): Declare this, too, if the system hasn't.
359 (scm_sleep, scm_usleep): Use scm_thread_sleep and
360 scm_uthread_sleep if they're available; otherwise, just call the
362 * scmconfig.h.in: Regenerated.
364 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
366 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
368 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
370 * threads.c: Doc fix.
372 The argument type of usleep varies from system to system,
373 as does the return type. We really shouldn't be redefining usleep
374 at all, but I don't have time to clean that up before the 1.3.
375 release. It's on the schedule for afterwards. (Thanks to Julian
377 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
379 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
380 * scmconfig.h: Regenerated.
382 * simpos.c (scm_software_type): Procedure deleted. This isn't the
383 right way to handle system variation. Autoconf's approach is the
385 * simpos.h (scm_software_type): Declaration deleted.
387 * script.c (scm_find_executable): Don't test if unix is #defined
388 here; first, NetBSD doesn't #define it, and second, it's the wrong
389 way to go about these things. (Thanks to Perry Metzger.)
390 (dld_find_executable): Delete this MSDOS support code. This isn't
391 the way we want to support this; it needs to be rethunk at a
394 * genio.c (scm_do_read_line): Don't just politely check that the
395 line was either non-empty or EOF. Abort if it's empty and not
398 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
400 * scmconfig.h.in: Regenerated.
402 * libguile.h: Don't omit the dynamic linking functions. (Thanks
405 * genio.c (scm_do_read_line): Count lines correctly when the file
406 doesn't end in a newline.
408 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
410 * genio.c (scm_do_read_line): Maintain the line count correctly.
411 (Thanks to Harvey J. Stein and Greg Harvey.)
413 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
416 * numbers.c (big2str): Protect t from garbage collection until
417 we're done. (Thanks to Gary Houston.)
419 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
421 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
423 * Makefile.in: Regenerated.
425 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
426 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
429 Do magic to mix reads and writes on stdio FILE-based ports.
430 (Thanks to Christian Lynbech.)
431 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
433 (pre_read, pre_write): New functions.
434 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
435 local_fputs): Call them.
436 (local_fflush): Mark the port as ready for reading and writing.
437 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
438 flags on new port objects. This might not be accurate --- who
439 knows what state the FILE * is in when we get it --- but it won't
440 do extraneous calls to fflush or fseek, so it's no worse than the
441 behavior before this change.
442 * ports.h: Add comment.
444 Centralize the creation of port objects based on stdio FILE * in
445 fports.c; don't just throw them together anywhere.
446 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
447 what the rest of Guile wants. Don't set the revealed count;
448 that's only appropriate for stdin, stdout, stderr.
449 (scm_standard_stream_to_port): This function does set the revealed
451 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
452 not scm_stdio_to_port.
453 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
454 * fports.c (scm_open_file): Same.
455 * posix.c (scm_pipe): Same.
456 * socket.c (scm_sock_fd_to_port): Same.
457 * ioext.c (scm_fdopen): Same.
458 (scm_freopen): Moved from here to...
459 * fports.c (scm_freopen): ... here. This is really something that
460 munges the internals of an fport, so it should go here.
461 * fports.h (scm_stdio_to_port): Adjust prototype.
462 (scm_standard_stream_to_port, scm_freopen): New protoypes.
463 * ioext.h (scm_freopen): Prototype removed.
465 * filesys.c (set_element, get_element): This can work on both pipe
466 and file ports, so use SCM_FPORTP to typecheck, instead of testing
469 * scmconfig.h.in: Regenerated.
471 Change the definition of the functions in scm_ptobfuns so that
472 they get passed the port object, not the port's stream.
473 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
474 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
475 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
476 Pass the port itself to the scm_ptobs function.
477 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
478 scm_generic_fgets): Same.
479 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
480 getc_void_port, fgets_void_port, close_void_port): Just change the
481 argument names; these functions don't really do anything.
482 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
483 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
484 port as an argument, and use SCM_STREAM to get the stdio FILE *.
485 Also, use prototyped definitions, and get rid of the extra
487 (scm_fptob, scm_pipob): We don't need casts here any more.
488 * strports.c (prinstpt): Use prototype declarations.
489 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
490 and use SCM_STREAM to get the string info. Also, use prototyped
491 definitions, and get rid of the extra declarations.
492 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
495 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
496 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
498 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
499 scm_fgets, for consistency.
500 (scm_fptop, scm_pipob): References updated.
502 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
504 Include the source location in error messages for scripts.
505 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
506 stack is still there when we catch the error.
507 * throw.c (handler_message): If we are handling an error with a
508 message, then put together the proper arguments and call
509 scm_display_error, instead of scm_display_error_message. That
510 displays source location, if it can find it.
512 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
514 * gc.c (scm_unprotect_object): Change this so that calls to
515 scm_protect_object and scm_unprotect_object nest properly.
516 (scm_protect_object): Doc fixes.
518 * strings.c (scm_string_set_x): Require the argument to be a
519 writable string, not a substring or a symbol.
520 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
521 (Thanks to John Redford and Charbel Jacquin.)
523 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
525 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
527 * eval.c (safe_setjmp): Remove this misunderstanding.
528 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
531 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
533 * libguile.h: Mark these as C declarations, for compilation by C++
536 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
537 __cplusplus clause. I seriously doubt this ever worked the way
538 the author seems to have intended.
540 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
542 Utterly needless cleanups to hopelessly messy code.
543 * ports.c: Doc fixes.
544 (scm_fflush): Moved to ...
545 * genio.c (scm_fflush): ... here, amongst all the other port
546 method invocation functions.
547 * genio.h, ports.h: The prototype moves too.
549 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
551 * backtrace.c (display_error_body): The current frame does not
552 always have a parent frame; consider a function called directly
553 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
556 * alloca.c (alloca): Undo yesterday's changes, and simply call
557 malloc directly for storage, and abort if we don't get what we
558 want. The situation is much simpler --- just call malloc. Emacs
559 has bizarre/evil requirements (signal handlers might malloc unless
560 you set this global flag, so you have to set the flag around all
561 calls to malloc) which we are certainly not going to conform to,
562 so we can do the simple and obvious thing.
564 * coop.c (coop_condition_variable_wait): Make this function
565 static. It's only useful internally --- you should never just
566 wait on a condition variable.
567 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
569 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
571 * unif.c (scm_array_set_x): Accept any kind of number as an
572 element for a uniform vector of doubles. This is more consistent
573 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
575 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
576 works; I can't conveniently test it myself. (Thanks to Dvid
577 Tillman for the bug report.)
581 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
582 from here, not from scm_compile_shell_switches (which is a pretty
583 dumb place to do it).
584 (scm_load_startup_files): New function.
585 (scm_ice_9_already_loaded): Variable moved to here from script.c.
586 * script.c (scm_compile_shell_switches): Don't load the startup
588 (scm_ice_9_already_loaded): Variable moved.
589 * init.c (scm_load_startup_files): Prototype for new function.
590 * gh_init.c (gh_enter): Doc fix.
592 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
594 Some anti-warning changes from Greg Harvey.
595 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
596 warnings when it doesn't understand our NORETURN declarations in
598 * posix.c (scm_mknod): Similar.
600 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
602 * posix.c (scm_getpwuid): If we can't find an entry, return our
603 own message, instead of using scm_syserror --- the getpwMUMBLE
604 functions don't set `errno' to anything interesting.
606 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
608 Get rid of warnings from the cooperative threading system.
609 * threads.h (scm_single_thread_p, scm_yield,
610 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
611 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
612 scm_wait_condition_variable, scm_signal_condition_variable): Add
613 prototypes for these Scheme-visible functions.
614 * coop-defs.h (coop_next_runnable_thread,
615 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
616 Prototypes for these here, even though they're from iselect.c.
617 (coop_condition_variable_wait, coop_join): Add prototypes.
618 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
619 scm_threads_free_condvar): Make these smob functions static.
620 * coop-threads.h (coop_init): Give this a real prototype.
621 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
622 (coop_next_runnable_thread): No need to provide prototype; it's in
625 * scmconfig.h.in: .detarenegeR
627 * iselect.c, threads.c: Doc fixes.
629 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
631 * Makefile.in: Regenerated with a patched automake, to get
632 dependency generation right when using EGCS.
634 * inet_aton.c (inet_aton): Add prototype, to remove compiler
635 warning. (Thanks to Robert Pluim.)
637 * inet_aton.c (inet_aton): Reassure the compiler that the
638 arguments to the <ctype.h> macros are all unsigned characters, not
641 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
643 Getting rid of more warnings...
644 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
645 today's change to ../configure.in.
646 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
647 * scmconfig.h.in: Regenertaded.de.,.__
648 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
649 (scm_localtime, scm_mktime): Use a const char * to manipulate the
652 * readline.c: Doc fix.
653 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
654 * readline.h (scm_filename_completion_function): Add prototype.
655 (scm_init_readline): Make this into a prototype.
657 * readline.c (scm_filename_completion_function): Use SCM_PROC to
658 declare this, instead of calling scm_make_subr manually.
660 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
662 * readline.h (scm_init_readline): Add prototype for this.
663 (scm_init_readline): Make this a real prototype.
665 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
667 Warning fixes from Maciej Stachowiak:
668 * backtrace.h (scm_display_application, scm_backtrace): Add
670 * debug.c (scm_m_start_stack): Make this function static.
671 * fluids.h (scm_fluid_p): Add prototype.
672 * procprop.c (scm_i_procedure_arity): Make this function static.
673 * regex-posix.c (scm_regexp_error_msg): Make this function static.
674 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
675 * root.h (scm_dynamic_root): Add external prototype.
676 * scmsigs.h (scm_usleep): Add external prototype.
677 * script.h (scm_init_script): Use prototype, not K&R decl.
678 * stacks.h (scm_stack_id): Add external prototype.
679 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
681 1998-09-30 Mark Galassi <rosalia@cygnus.com>
683 * gh.h: took out the definitions of vset and vref, since they are
684 replaced by the proper vector routines that correspond to the R4RS
687 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
689 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
690 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
691 third argument, a C expression that should result in a SCM value,
692 which is used to initialize the variable. Reimplemented
693 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
696 * version.h (scm_libguile_config_stamp): Add prototype.
697 (From Maciej Stachowiak.)
699 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
701 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
702 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
704 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
706 * print.c (scm_iprin1): Rather than having one i, and using it in
707 several places, declare a fresh i local to each block where it is
708 used, and give it a signedness appropriate to its use in each case.
711 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
714 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
715 signed/unsigned clashes.
717 * posix.h (scm_tmpnam): Added prototype.
719 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
720 scm_make_subclass_object): Add external prototypes.
722 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
723 comparison is okay here.
725 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
727 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
728 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
730 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
733 * load.c (swap_port): Make this function static.
735 * load.c (scm_search_path): Make max_path_len and max_ext_len
736 unsigned, since they're compared against string sizes.
738 * load.c (init_build_info): Make i unsigned.
740 * ioext.h (scm_read_line): Add prototype.
742 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
743 scm_hash_fn_remove_x): Make hash bucket index local variable k
744 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
745 accurately as possible.
747 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
748 comparisons, and range checking to make sure those casts are
751 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
752 signed/unsigned comparisons.
754 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
755 avoid signed/unsigned comparisons.
756 * smob.h (scm_numsmob): Change extern declaration to match.
758 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
759 avoid signed/unsigned comparisons.
760 * ports.h (scm_numptob): Change extern declaration to match.
761 (scm_current_load_port, scm_set_port_line_x,
762 scm_set_port_column_x): New prototypes.
764 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
765 test code, and it causes warnings.
767 * gh.h (gh_int2scmb, gh_uniform_vector_length,
768 gh_uniform_vector_ref): Added prototypes.
770 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
771 debugging support unconditionally. That's backtrace.c, stack.c,
772 debug.c, and srcprop.c.
773 (EXTRA_libguile_la_SOURCES): Omit those from here.
774 * Makefile.in: Regenerated.
776 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
778 * options.c (scm_options): Bugfix: Allow empty list of options!
780 * debug.c, debug.h (scm_single_step): Removed.
781 (scm_with_traps): New procedure. This procedure could easily be
782 written in Scheme but needs to be highly optimized.
784 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
786 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
787 Check SCM_TRAPS_P before trapping.
789 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
791 Changes to avoid signed/unsigned comparison warnings.
792 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
793 (scm_gc_sweep): Make n and j local to the blocks they're used in,
794 so they can have appropriate types for each application. Make i
795 signed. Use initializers in some spots. I'll probably pay for
797 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
798 (scm_must_realloc): Make nm unsigned.
799 (init_heap_seg): Make new_seg_index and n_new_objects signed.
800 (scm_init_storage): Use prototype-style definition, and make the
802 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
803 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
805 * filesys.c (scm_readlink): Make local vars rv and size ints, to
806 avoid signed/unsigned comparison warnings, and because the return
807 value of readlink may be -1. Don't bother casting the third
808 argument to readlink.
810 * filesys.c (scm_dirname, scm_basename): Move these to their own
811 page, at the end of the file.
812 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
814 * eval.h (scm_eval_options_interface): Add external prototype for this.
815 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
817 * eval.c (scm_lookupcar1): Make this static.
819 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
820 Make these prototype declarations, not K&R-style.
822 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
823 unsigned comparison warning.
825 * appinit.c: File removed. It had a single function in it, empty,
826 whose reason for existence is explained in no documentation or
827 comment. I think it's there as a default for some Tcl-style
828 initialization, but Tcl abandoned that approach a while ago.
829 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
830 (BUILT_SOURCES): Remove appinit.x.
831 * Makefile.in: Regenerated.
833 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
835 * Makefile.in: Regenerated using the last public version of
836 automake, not the hacked Cygnus version.
838 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
840 Remove Totoro kludge.
841 * Makefile.in, scmconfig.h.in: Regenerated.
842 * init.c, readline.c: Don't check if TOTORO is #defined.
844 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
846 * Makefile.am: Adjust for new thread configuration system.
847 (INCLUDES): Include the value of THREAD_CPPFLAGS.
848 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
850 (THREAD_LIBS): Definition deleted; automake will generate such
851 things automatically.
852 * Makefile.in: Regenerated.
854 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
856 Simplify smob and port marking; set the mark bit in the generic
857 marking code, and make marker routines only responsible for
858 turning up outgoing pointers.
859 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
860 before calling the marking function. Don't call the marking
861 function if it's zero.
862 * markers.c (scm_mark0): Just return #f. This function isn't
863 necessary at all now, but it's harmless to call it. We'll leave
864 it in so other folks' code doesn't croak at link time.
865 (scm_markcdr): Don't call SCM_SETGC8MARK.
866 * async.c (mark_async): Don't call SCM_SETGC8MARK.
867 * dynl.c (mark_dynl_obj): Same.
868 * root.c (mark_root): Same.
869 * srcprop.c (marksrcprops): Same.
870 * unif.c (markra): Same.
871 * variable.c (scm_markvar): Same.
872 * ports.c (scm_markstream): Same.
873 (void_port_ptob): Specify zero for our marking function.
874 * debug.c (debugobjsmob): Same.
875 * dynwind.c (guardsmob): Same.
876 * filesys.c (dir_smob): Same.
877 * fluids.c (fluid_smob): Same.
878 * fports.c (scm_fptob, scm_pipob): Same.
879 * mallocs.c (mallocsmob): Same.
880 * regex-posix.c (regex_t_smob): Same.
881 * smob.c (freecell, flob, bigob): Same.
882 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
883 * throw.c (jbsmob, lazy_catch_funs): Same.
885 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
887 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
888 scm_copy_tree on code in order not to let memoized code to leak
889 out. Thus, scm_copy_tree needs to copy vectors as well since
890 quasiquote can introduce evaluated code also inside vector
893 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
895 * eval.c (scm_copy_tree): Removed ability to copy vectors.
897 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
898 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
901 * unif.c: Say that ivect and uvect are of type signed and unsigned
902 long instead of int in commentary so that it correctly describes
905 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
907 * stime.c: Removed declaration of strptime. (It should be
908 declared by the system headers. If it turns out that some systems
909 don't, we'll handle that then.) (Thanks to Greg Troxel.)
911 * stime.h: Renamed TIMEH --> STIMEH
913 * backtrace.c (scm_display_error, scm_display_backtrace): In order
914 to increase portability, don't use structure assignment.
915 (Thanks to Nicolas Neuss.)
917 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
919 (finalize_fd_sets): Added empty statement after last case label.
920 (Thanks to Nicolas Neuss.)
922 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
925 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
927 * init.c, readline.c: OK, I won't have these readline.x bug
928 reports anymore. We've had them since April. The current reason
929 is a completely unintelligible failure of totoro.red-bean.com to
930 do the test for rl_getc_function in libreadline correctly. This
931 kludge overrides the test if we're on totoro so that the snapshot
932 generation process can work.
934 * readline.c: Define a strdup replacement if not existent on system.
936 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
938 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
939 This change makes scm_make_vector R5RS compatible. We cannot keep
940 the third argument since people want to be able to deduce the form
941 of the C function call only by looking at R5RS. (At the same time
942 we have removed some unnecessary complexity!)
944 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
945 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
946 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
947 argument in call to scm_make_vector.
949 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
951 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
952 This macro is useful in applications.
954 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
956 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
957 (scm_parse_path, scm_search_path): New Scheme level procedures.
959 * load.h (scm_internal_parse_path, scm_parse_path,
960 scm_search_path): Declared.
962 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
964 * filesys.c (dirname, basename): New procedures.
966 * init.c (scm_boot_guile_1): Removed condition around
969 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
970 new data type (guards) for representation of C level guards and
971 data on the wind chain.
972 (scm_internal_dynamic_wind): New function.
974 * dynwind.h: Declare scm_internal_dynamic_wind.
976 * root.h (scm_root_state): Added scm_cur_loadp.
978 * root.c (mark_root): Added comment about cur_loadp.
980 * load.c: #include "dynwind.h";
981 (scm_primitive_load): Use scm_inner_dynamic_wind to update
984 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
986 * ports.c (current-load-port): New procedure.
988 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
990 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
991 not a tty, return #f.
993 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
994 to Julian Satchell and Roland Kaufmann.)
996 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
997 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
999 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1001 * debug.h, debug.c (scm_start_stack): New function. Implements
1002 the guts of old scm_m_start_stack.
1004 * debug.c (scm_m_start_stack): Use scm_start_stack.
1006 * init.c (scm_start_stack, scm_restart_stack): Renamed to
1007 start_stack and restart_stack. (These have static scope.)
1009 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1011 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
1012 readline functions to come in release 2.3. (Thanks to Chet
1014 (handle_errors): Use the above functions.
1016 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1018 * readline.c: Improvements for readline support: Handle errors
1019 better; Implement before-read-hook.
1021 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1023 * init.c (scm_boot_guile_1), readline.c: Test for
1024 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
1025 assure that we have version >= 2.1.)
1027 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
1029 * readline.c (scm_readline): Defer interrupts while we're calling
1032 * readline.c (scm_add_history): Bugfix: Do strdup before giving
1033 away the string to add_history.
1034 (completion_function): Do completion for readline. (Thanks to
1036 (scm_filename_completion_function): New procedure: Filename
1038 (current_input_getc): New function. Use this one instead of
1039 standard getc from readline.
1041 * throw.c, throw.h (scm_handle_by_throw): New function: This
1042 handler throws errors to next handler on the dynwind chain.
1044 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
1046 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
1049 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1051 * procprop.c (scm_i_procedure_arity): New function. Returns arity
1053 (scm_procedure_properties): Modified to return arity together with
1055 (scm_procedure_property): Added the read-only property `arity'.
1056 (scm_set_procedure_property_x): It is an error to set the `arity'
1059 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
1060 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
1062 * procprop.h (scm_sym_arity): New symbol.
1064 * objects.c (scm_set_object_procedure_x): New procedure: Use this
1065 to set the dispatch procedure of an operator or entity object.
1067 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
1068 Made procedure slots read-only.
1070 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
1071 scm_tcs_cons_gloc case in zero args switch; Fixed args
1072 construction for operators in scm_tcs_cons_gloc case in two args
1075 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1077 * fluids.c: Removed use of assert.h (in order to avoid
1080 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
1082 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
1084 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
1085 change makes the evaluator safer at the cost of evaluation speed.
1086 It handles the case when the user has added a non-immediate
1087 improper end of the application form, e.g., `(+ 0 . x)'.
1088 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
1089 minimize the extra cost as much as possible. The new code is
1090 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
1091 problem with structs planted directly in the code (e.g. by a
1092 macro). This no longer causes segmentation fault. (Thanks to
1095 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
1096 arg `proc' in order to be able to throw errors; New argument
1099 * Removed extra #include "debug.h"
1101 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
1103 * scmsigs.c: Declare usleep as returning void on some systems.
1104 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
1107 * coop.c (usleep): Return void on some systems.
1109 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1111 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
1113 * coop.c: Changed return type of usleep to int.
1115 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
1116 isn't found in the OS.
1118 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
1119 isn't enabled. (Thought that I had made this change ages ago...)
1121 * iselect.c: Declare bzero if not defined by OS.
1123 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1125 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
1126 condition. (Thanks to John Tobey.)
1128 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
1129 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
1132 * __scm.h: Start the long-term project of moving to POSIX threads.
1133 Phase 1: Classification of all critical sections.
1134 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
1135 for A sections. (See comments in __scm.h for details.)
1137 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
1138 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
1140 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1142 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
1143 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
1144 (libpath.h, versiondat.h): Replaced dependency on Makefile with
1145 dependencies on $(srcdir)/Makefile.in
1146 $(top_builddir)/config.status in order to avoid circularity.
1148 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
1149 from argc if argc was 0 initially.
1151 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
1152 in generation of libpath.h.
1154 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
1156 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
1157 libguile from 2 to 3.
1159 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
1161 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
1163 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
1165 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
1166 scm_set_port_column_x, scm_port_filename,
1167 scm_set_port_filename_x): Removed optional arguments. Added
1168 proper argument checking.
1170 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
1171 stack size in machine words.
1173 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
1174 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
1175 to Ole Myren Röhne.)
1177 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
1179 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
1180 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
1182 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
1185 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
1186 procedure apply: Copy argument lists before pushing them unto the
1187 environment so that the environment won't get mutated due to
1188 manipulation of procedure arguments. This should perhaps be
1189 regarded as a temporary solution until someone finds a more
1190 efficient one. (Thanks to Maciej Stachowiak.)
1192 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
1194 * script.c (scm_compile_shell_switches): Use "guile" as default
1195 zero arg if argc is NULL.
1197 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
1199 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
1200 is zero. (Thanks to Dirk Herrmann.)
1202 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
1204 * ports.c (scm_add_to_port_table): First line is now line 0
1205 (was 1). (Interface changed according to suggestion by Per
1208 * backtrace.c (display_header): Add 1 to line and column numbers
1209 when presenting them to the user.
1211 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
1212 from debug.c --> eval.c
1214 * eval.h, eval.c (scm_eval_options_interface): New options
1216 (SCM_EVAL_STACK): New option: Size of newly created stacks,
1217 i.e. stacks for new threads.
1219 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
1221 * eval.c (unsafe_setjmp): Removed with #if 0.
1223 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
1226 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
1227 to avoid compiler warnings.
1229 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
1231 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
1233 * throw.c (handler_message): Print message on current error port
1234 instead of default error port. (Thanks to Maciej Stachowiak.)
1236 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
1238 * ports.c (scm_add_to_port_table): allocate in units of
1239 struct scm_port_table *, not struct scm_port_table.
1240 * posix.c (scm_close_pipe): remove the port from the port table
1242 Thanks to Rob Engle for both fixes.
1244 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1246 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
1247 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
1249 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1251 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
1253 * backtrace.c (display_error_body, display_backtrace_body),
1254 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
1255 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
1256 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
1257 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
1260 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
1261 don't receive the jmpbuf arg anylonger.
1262 (scm_catch): Don't accept a #f tag.
1263 (scm_throw): Check that key is a symbol.
1264 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
1266 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
1268 * async.c (async_pending): Removed declaration.
1270 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1272 * dynwind.c (scm_wind_chain): New debug function.
1274 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
1275 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
1276 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
1277 extra layer of functions around the body and handler of a thread.
1278 This extra layer makes sure that the handler is called in the
1279 dynamic context of the surround (= empty dynwind list), but under
1280 the *dynamic root* of the body. We can not use the dynamic root
1281 of the surround since that root belongs to another thread => stack
1282 is not handled correctly. It may seem ugly to use this extra
1283 layer, but the extra cost in terms of execution time is really
1284 negligible compared to the total amount of time required to create
1285 a thread, and it would reduce maintainability to duplicate the
1286 crucial and complicated steps performed by cwdr.
1288 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
1289 (SCM_ALLOW_INTS): Added thread switching code before interrupts
1290 get re-enabled. The important effect of this is that interrupts
1291 are blocked during thread switching so that thread data structures
1292 don't risk getting messed up by an unfortunate signal.
1293 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
1294 seems to do more aggressive optimization which actually move
1295 instructions around in these macros in a fatal way. Therefore:
1296 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
1297 just superstitious...)
1298 (SCM_TICK): Maybe do a context switch and take care of asyncs.
1299 This macro should be used instead of SCM_ASYNC_TICK since the
1300 latter doesn't do context switches any more.
1302 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
1303 instead of SCM_ASYNC_TICK.
1305 * coop.c, iselect.c: Since thread switches are now performed with
1306 interrupts masked, we can't use the old mechanism of delivering
1307 signals immediately when they arrive. Signals must instead be
1308 delivered when the asyncs run *after* the end of the critical
1309 section in scm_internal_select. But this also means after context
1310 switch so that the signal will be delivered to a different thread.
1311 To avoid this, I have changed the protocol of
1312 coop_wait_for_runnable_thread and friends so that they are allowed
1313 to return the original thread. So, if a signal arrives during
1314 scm_internal_select, we won't any longer be forced do a context
1315 switch, but can remain in the same thread and deliver the signal
1318 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
1319 scm_asyncs_pending and made it global.
1321 * iselect.c: Small fixes.
1323 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
1324 coop_condition_variable_init, coop_condition_variable_wait,
1325 coop_condition_variable_signal): Changed return type from `void'
1326 to `int'. This is to adhere closer to the pthreads interface.
1327 This, in turn, is part of an attempt to provide C versions of the
1328 mutex and condition variable primitives which can be part of a
1329 frontend to COOP or pthreads.
1331 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
1332 coop_condition_variable_destroy): New functions.
1334 * coop-threads.c (scm_wait_condition_variable): Use
1335 coop_condition_variable_wait_mutex.
1337 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
1338 Definitions moved to coop-defs.h.
1340 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
1341 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
1342 scm_cond_destroy): New C interface to mutecis and cond vars.
1344 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1346 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
1348 * iselect.c: Now several threads can wait on the same file
1349 descriptor. The behaviour is compatible with OS select: All
1350 threads waiting for the fd return with the same status.
1352 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1354 * coop-threads.c, threads.h (scm_spawn_thread): New function.
1355 Can spawn a thread from application C code.
1357 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1359 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
1360 gh_doubles2scm): New functions.
1362 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
1364 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
1365 commented-out version of gh_eval_str()
1367 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
1369 * socket.c (scm_bind): free soka after use.
1371 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
1373 * stime.c (tzvar): new variable.
1374 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
1375 avoid memory leaks when allocating.
1377 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
1379 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
1382 * gc.c, tags.h: Doc fixes.
1384 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1386 * eval.c (macro-eval!): Removed. This function was a design bug.
1387 It allowed memoized code to leak out to the scheme level. Most
1388 things that you could do with `macro-eval!' can be done with
1391 1997-12-20 Tim Pierce <twp@skepsis.com>
1393 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
1394 scm_fgets now depends on ftell(3) to know how many bytes were
1397 1997-12-15 Tim Pierce <twp@skepsis.com>
1399 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
1400 dealing with strings.
1402 1997-12-13 Tim Pierce <twp@skepsis.com>
1404 Make %read-line more suitable for implementing read-line efficiently.
1405 * ioext.c (scm_read_line): Strip the terminating newline from a
1406 string, and return a cons of the string and its terminator.
1408 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
1409 of the string that is read is stored in this memory location.
1410 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
1411 * genio.c, genio.h (scm_do_read_line): Update caller.
1412 * ports.h (scm_ptobfuns): Update typedef.
1413 * fports.c (scm_fptob, scm_pipob): Update struct.
1415 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1417 * filesys.c (set_element): Return file descriptor.
1418 (fill_select_type): Return the highest file descriptor.
1419 (scm_select): Tell select about the highest file descriptor. On
1420 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
1421 Therefore the extra overhead for calculating the maximum fd seems
1422 to be more than compensated. Is this correct? In any case,
1423 scm_internal_select will be much faster with this info.
1424 (scm_select, fill_select_type, set_element): Don't accept any kind
1425 of object in the file descriptor list or vector.
1427 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1429 * iselect.c (finalize_fd_sets): Bugfix.
1431 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1433 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
1434 when using scm_internal_select (since we might switch to another
1437 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1439 * simpos.c (scm_system): always define: use sysmissing if not
1440 available. Check for HAVE_SYSTEM instead of _Windows (does
1441 Windows lack system or does it have an unusable one?).
1442 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
1443 Let the argument be optional: if not supplied, call system(NULL).
1445 * ports.c (scm_close_port): relax the type check from OPPORTP to
1446 PORTP; closing a closed port is allowed.
1448 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
1450 * fports.c (scm_fgets): Return if the last char in a chunk is
1451 newline. When fgets returns a string whose length is `size-1', it
1452 is ambiguous whether a whole line was retrieved, so we must check
1453 explicitly whether a line terminator is present.
1455 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1457 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
1458 before taking the CDR. (Thanks to Harald Meland.)
1460 * filesys.c (scm_stat): Slightly optimized.
1462 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
1464 * ports.c (scm_close_port): Make sure the port is open before
1467 * guile-snarf.in: Pass args through to gcc in a way that preserves
1468 whitespace boundaries. (Thanks to Greg Badros.)
1470 1997-12-02 Tim Pierce <twp@skepsis.com>
1472 * stacks.c (scm_frame_procedure): Reverse the logic in the return
1473 statement. (Thanks to Doug Evans for pointing this out.)
1475 1997-12-01 Tim Pierce <twp@skepsis.com>
1477 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
1479 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
1481 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
1482 errno macro expansion of this field name. (errno is a C
1483 preprocessor macro on some systems.)
1485 1997-11-29 Tim Pierce <twp@skepsis.com>
1487 * iselect.c: Doc fix.
1489 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
1491 * init.c (scm_start_stack): Removed initialization of
1492 scm_the_last_stack_var.
1494 * backtrace.h: Declare scm_the_last_stack_var.
1496 * backtrace.c: Define scm_the_last_stack_var.
1498 * root.c (mark_root): Don't mark the_last_stack_var.
1500 * root.h (scm_root_state): Removed the_last_stack_var.
1502 * throw.c: Added #include "fluids.h"
1503 (ss_handler): `the-last-stack' is now a fluid.
1505 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
1506 --> the_last_stack_fluid.
1508 * backtrace.c: Added #include "fluids.h"
1509 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
1510 (scm_backtrace): `the-last-stack' is now a fluid.
1512 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
1513 after scm_init_fluids.
1515 1997-11-28 Tim Pierce <twp@skepsis.com>
1517 * iselect.c: #ifdef USE_THREADS around thread-related includes.
1519 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
1520 DLSYM_ADDS_USCORE to decide whether to add an underscore.
1522 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1524 * iselect.c (coop_next_runnable_thread,
1525 coop_wait_for_runnable_thread): Disable interrupts so that no
1526 async is executed before a potential error_revive.
1527 (scm_internal_select): Disable interrupts during the parts of the
1528 code which manipulate the sleep queue and the file descriptors.
1530 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1532 * Makefile.am: Added iselect.c and iselect.h.
1534 * coop.c (coop_qinit): Initialize fields used by
1535 scm_internal_select.
1536 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1537 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1538 replacement in iselect.c.
1539 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1540 coop_join): If GUILE_ISELECT enabled, use
1541 coop_wait_for_runnable_thread instead of
1542 coop_next_runnable_thread.
1543 (usleep, sleep): New replacements for system functions if
1544 GUILE_ISELECT is enabled.
1546 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1548 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1550 * filesys.c: Added #include "iselect.h". Moved FD-macros to
1551 iselect.h. Implement Scheme level `select' using
1552 scm_internal_select. (See NEWS.)
1554 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1556 * init.c: Call scm_init_iselect.
1558 * iselect.h, iselect.c: New files. Implements
1559 scm_internal_select. (See NEWS.)
1561 1997-11-27 Tim Pierce <twp@skepsis.com>
1563 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1564 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1565 and scm_must_free, since ultimately the string returned will be copied
1566 by scm_makfrom0str anyway. Also, read any characters that may have
1567 been pushed onto the port with scm_ungetc.
1568 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1569 * ioext.c (scm_read_line): Free string after Guilifying it.
1570 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.

1578 1997-11-25 Mark Galassi <rosalia@cygnus.com>
1580 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
1581 gh_repl (argc, argv).
1583 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1585 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1586 and to invoke scm_shell().
1587 (gh_launch_pad): took out the loading of boot-9.scm from here,
1588 since it is probably best to let the user control that. In fact,
1589 gh_repl() now invokes scm_shell() which does that.
1591 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1593 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
1596 1997-11-22 Tim Pierce <twp@twp.tezcat.com>

1610 (gh_uniform_vector_ref): started implementing the uniform types in
1613 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
1615 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1616 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1618 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1620 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1621 configure.in was changed).
1623 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
1625 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1626 * Makefile.in: Regenerated.
1628 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1630 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1631 OPORT is an `open' port, not an output port.
1633 * filesys.c (scm_close, set_element, get_element, scm_chown,
1634 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
1635 SCM_COERCE_OUTPORT to cope with the printstate/port magic.

1638 scm_port_column, scm_set_port_column_x, scm_port_filename,
1639 scm_set_port_filename_x, scm_port_mode,
1640 scm_close_all_ports_except, scm_set_current_output_port,
1641 scm_set_current_error_port): Likewise
1642 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1643 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
1645 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
1646 * backtrace.c (display_backtrace_body): Likewise
1647 * fports (scm_setvbuf): Likewise
1648 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
1649 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,

1651 * unif.c (scm_uniform_array_write): Likewise
1653 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
1655 Minor problems with substring-related tag changes.
1656 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1657 exactly what we want to leave in to detect substrings.
1658 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1659 * tags.h: Fix diagrams and comments describing the S tag bit;
1660 remove vestigial remarks about the D tag bit.
1661 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
1662 * strings.c: Formatting tweaks.
1664 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1665 variable first; then SCHEME_LOAD_PATH, with a warning message.
1666 (scm_parse_path): New function.
1667 * script.c: Doc fixes.
1669 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1671 Readline support, from Daniel Risacher.
1672 * readline.c, readline.h: New files.
1673 * init.c: #include "readline.h".
1674 (scm_boot_guile_1): Call scm_init_readline, if we have it.
1675 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1676 * Makefile.in: Regenerated.
1677 * scmconfig.h.in: Regenerated, after change to ../configure.
1679 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1681 * gh.h: gh_vector_set -> gh_vector_set_x
1683 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1685 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1686 with the ! -> _x mapping when going from Scheme to C.
1688 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1690 * gh.h (gh_reverse):
1698 (gh_assoc): added these gh_ functions implemented as macros.
1700 * gh_predicates.c (gh_null_p):
1701 (gh_string_equal_p): added these two missing predicates.
1703 * gh_list.c (gh_append):
1708 (gh_set_cdr_x): added these routines as I go through and try to
1709 complete the picture R4RS functions that should be mirrored in the
1712 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1714 * tags.h (scm_tc7_substring): Changed the comment and code to
1715 conform with the changes below. Folks! We have suddenly two new
1716 free tc7 codes!!! Jummy, jummy!
1718 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
1720 * Makefile.in: Rebuilt.

1741 (scm_tc7_mb_string): Removed.
1742 (scm_tc7_mb_substring): Removed.

1745 Don't include "mbstrings.h".
1746 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
1747 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
1749 Don't include "mbstrings.h".
1750 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
1751 (SCM_SYMBOL_SLOTS): Define as 4.

1753 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
1754 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
1755 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
1756 struct.c, threads.c, throw.c, unif.c, variable.c: Use new

1773 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
1774 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
1776 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1778 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1780 * gh_test_c.c (c_vector_test): some improvements on the vector
1783 * gh.h (gh_vector): this used to exist but do the wrong thing.
1784 Now it (almost) does the right thing, though it takes a list
1785 instead of the individual arguments. I need to see how it could
1787 (gh_list_to_vector): added this function as a macro. Corresponds
1788 to Scheme's (list->vector ...).
1789 (gh_vector_to_list): added this function as a macro. Corresponds
1790 to Scheme's (vector->list ...).
1792 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1793 gh_vector_ref, so that it resembles the Scheme routines more.
1794 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1795 resembles the Scheme routines more.
1796 (gh_make_vector): this used to be (stupidly) called gh_vector().
1797 This is the right name, since it does the same thing as the Scheme
1798 (make-vector ...) procedure.
1800 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1802 * ports.h: #include "libguile/print.h"
1804 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
1805 Some indentation fixes.
1807 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
1808 longer a user field; New field: class_flags.
1810 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
1812 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
1814 * gh_data.c (gh_bool2scm): new function which replaces
1815 gh_int2scmb(), which is now tagged as obsolete.
1817 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1819 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1820 macros should by convention not test for NIMPness.)
1821 (SCM_COERCE_OPORT): Adjust indentation.
1823 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1824 SCM_NIMP test before SCM_PRINT_STATE_P.
1826 * struct.c, struct.h, gc.c: Renamed:
1827 scm_struct_i_layout --> scm_vtable_index_layout
1828 scm_struct_i_vcell --> scm_vtable_index_vcell
1829 scm_struct_i_vtable --> scm_vtable_index_vtable
1830 scm_struct_i_printer --> scm_vtable_index_printer
1831 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1833 * struct.c (scm_print_struct): Use new printer slot; Default
1834 printing: Also output hex code of vtable so that type identity
1835 will be indicated as well.
1836 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1837 Removed struct_printer_var; Removed struct-vtable-offset;
1838 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1839 vtable-offset-user): New constants.
1841 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
1842 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
1843 If this slot contains a procedure, use that to print structures of
1844 the type represented by this vtable.
1846 * print.c (scm_iprin1): Don't print arguments of macro
1847 transformers. (They are always: exp env.); Bugfix: Unmemoize
1848 transformer source with correct environment.
1850 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1852 Streamlining of call-with-dynamic-root:
1854 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
1855 there is now only one catch.
1856 (cwdr_outer_body): Removed.
1857 (cwdr_handler): New function.
1858 (scm_internal_cwdr): New function to perform the function of cwdr
1859 but take args that are more useful to C code. Also, the handler
1860 is now invoked *outside* of the new dynamic root, like the docs
1861 say. We no longer have to catch absolutely all errors, the caller
1862 is responsible for using a handler that does not throw, if he
1864 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1865 * root.h (scm_internal_cwdr): New prototype.
1867 Even more but risky streamlining:
1869 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1870 allocation of the jumpbuf of a root continuation. The changes
1871 below are controlled by it. They are now deactivated.
1872 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1873 the JMPBUF of the scm_rootcont to NULL before returning.
1875 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1876 when they are non-NULL.
1877 (scm_gc_mark): Likewise, mark only when non-NULL.
1879 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1880 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1882 * gc.c (scm_done_malloc): New function.
1883 gc.h (scm_done_malloc): New prototype.
1885 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.

1892 a certain value is acceptable as a port argument.
1893 (scm_print_state_vtable): New variable.
1894 (scm_free_print_state): Set `revealed' field to false.
1895 (scm_iprin1): Call user supplied closure printer with
1896 scm_printer_apply. Print in the traditional way when there isn't
1897 one or when it returns #f.
1898 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1899 Accept a port/print-state pair in addition to just a port.
1900 (scm_prin1): Don't return the print_state to the pool when it has
1902 (scm_printer_apply): Set `revealed' field of print_state to true.
1903 (scm_init_print): Set scm_print_state_vtable.
1904 (print_state_fluid, print_state_fluid_num): Removed.
1906 * throw.h (scm_handle_by_proc_catching_all): New prototype
1907 throw.c (scm_handle_by_proc_catching_all): New function
1909 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1911 * Makefile.in: Regenerated with automake 1.2c.
1913 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1915 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1916 was looping endlessly.
1918 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1920 * strports.c (scm_eval_string): Don't close the port.
1922 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1923 former returns a nice normal integer. (Thanks to Daniel
1926 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1928 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1929 makefile variable as a build parameter called LIBS. The
1930 build-guile program will use this, for the time being.
1931 * Makefile.in: Regenerated.
1933 Thanks to Shiro Kawai:
1934 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1935 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1938 * Makefile.in: Regenerated with automake 1.2a.
1940 * script.c (scm_compile_shell_switches): If we hit the -c or --
1941 arguments, don't set the car of (command-line) to scm_usage_name,
1942 the prettified name of the guile executable; give it the full
1943 path, the way shells usually handle $0.
1945 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1947 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1948 Scheme-level name `array-map' and renamed `serial-array-map' to
1949 `serial-array-map!'.
1951 * backtrace.c: Introduced exception handlers which now enclose
1952 `display-error' and `display-backtrace' so that error reporting
1953 won't get into infinite loops if an error occurs during displaying
1954 of the error. This can very easily happen with user supplied
1955 print call-back routines.
1957 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1959 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1960 the names `serial-array-map' and `array-map' should be removed.)
1962 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1964 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1965 Added #include "objects.h"
1967 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1968 Add #include "feature.h".
1970 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1971 (modinclude_HEADERS): Added objects.h.
1973 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1974 This test is needed at many places in the code and should be
1975 abstracted. (Motivated by the need of this test in libguiletk.)
1977 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1978 (scm_eval_string), load.c (scm_primitive_load,
1979 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1980 Use SCM_EOF_OBJECT_P.
1982 * eval.c (scm_init_eval): Add feature `delay'.
1984 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1986 * scmhob.h: Removed.
1988 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1990 * list.h (SCM_LISTn): New macros. Make list creation in C code
1991 prettier. The idea comes from STk.
1993 * sequences.h, sequences.c, append.h, append.c: Removed. These
1994 files implemented non-R4RS operations which would encourage
1995 non-portable programming style and less easy-to-read code.
1997 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
2000 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
2001 sequences.h, #include append.h.
2003 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
2006 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
2008 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
2010 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
2012 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>

2016 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
2019 * smob.c (scm_smob_prehistory): Create two objectsmobs with
2020 adjacent smob numbers.
2022 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2024 * procprop.h: Added declaration of scm_i_inner_name.
2026 * gsubr.c: New global symbol scm_i_inner_name.
2028 * debug.c (scm_procedure_name): Try procedure property
2029 `inner-name' if `name' fails.
2031 * print.c (scm_iprin1): Use scm_macro_name.
2033 * eval.c (scm_m_define): Give names to macros as well; Only the
2034 first top-level definition gives a procedure/macro a name.
2035 Otherwise confusing names can turn up in backtraces.
2036 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
2037 `name'; Give names to macros as well.
2039 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
2040 (scm_macro_transformer): Use SCM_CLOSUREP instead of
2043 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2045 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
2047 (prinmacro): Removed. The code has been moved/merged into print.c
2048 in order to decrease code redundancy. We want macros to print in
2049 a way equivalent to procedures, and it would be silly to duplicate
2050 the required code. (We don't want to maintain two places.)
2051 (macrosmob): Print field is now a NULL pointer.
2053 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
2054 scm_macro_transformer): New prototypes.
2055 (scm_tc16_macro): Declared.
2057 * print.c (scm_iprin1): Added code for printing of macros. Macros
2058 are now printed in a way equivalent to procedures.
2060 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
2062 * procs.h (scm_closure_p): Added declaration.
2064 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2066 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
2067 Shouldn't pass "heap" as the subr name.
2069 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
2071 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
2072 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
2073 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
2074 gh_equal_p): Use SCM_NFALSEP, instead of testing against
2075 SCM_BOOL_T. Any non-false value is true.
2077 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2079 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
2080 scm_gensym): Added prototypes.
2082 * symbols.c (scm_gensym): New function. This will speed up
2083 certain types of applications (such as macro systems) which
2084 generate lots of symbols.
2086 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2088 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
2090 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
2092 * unif.c (scm_shap2ra): tighten the checking of the array dimension
2093 specifier, since (2) or (2 . 3) would cause SEGV.
2094 (scm_transpose_array): more argument checking fixes.
2096 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
2098 * Makefile.in: Regenerated.
2100 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
2102 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
2104 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2106 * error.c, error.h (scm_error_callback): Removed (see NEWS).
2108 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
2110 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
2111 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
2114 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
2115 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
2116 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
2117 scm_array_p, scm_array_rank, scm_array_dimensions,
2118 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
2119 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
2120 scm_array_prototype): Added case scm_tc7_wvect.
2122 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
2124 * errno.h: prototype for scm_strerror.
2125 * error.c (scm_strerror): new procedure.
2127 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2129 * list.c (scm_list_append_x): Allow non-pair as last argument.
2130 This is consistent with the R4RS append and is probably the
2131 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
2133 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2135 * stime.h: prototype for scm_times.
2136 * stime.c (scm_times): new procedure.
2137 * ioext.c (scm_fseek): if the first argument is a file descriptor
2139 (scm_ftell): if the first argument is a file descriptor call lseek
2141 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
2142 * filesys.c (scm_chmod): if the first argument is a file descriptor,
2144 (scm_chown): if the first argument is a port or file descriptor,
2146 (scm_truncate_file): new procedure.
2147 Add DEFER/ALLOW INTS to a few other procedures.
2148 (scm_fsync): new procedure.
2149 (scm_open_fdes): new procedure.
2150 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
2152 (scm_fcntl): the first argument can now be a file descriptor. The
2153 third argument is now optional.
2155 * posix.c (scm_execl, scm_execlp): make the filename argument
2156 compulsory, since omitting it causes SEGV.
2157 (scm_sync): return unspecified instead of #f.
2158 (scm_execle): new procedure.
2159 (environ_list_to_c): new procedure.
2160 (scm_environ): use environ_list_to_c. disable interrupts.
2161 (scm_convert_exec_args): take pos and subr arguments and
2162 improve error checking.
2164 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2166 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
2167 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
2168 argument to SCM_ASSERT. Furthermore, the name of the function
2169 should be passed as first argument when signalling
2170 SCM_WNA. (Thanks to Thomas Morgan)
2172 * gsubr.c (scm_gsubr_apply): From Radey Shouman
2173 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
2174 dispatches on the number of actual args has a default case
2175 reporting an internal error. This is a vestige from a version
2176 that mallocated a SCM vector to hold the arguments. In the
2177 current version this check is too late: if it ever happens we will
2178 have already overstepped the bounds of the array.
2180 Also, the patch [...] adds a check for too many actual arguments."
2182 mdj: Removed check for "internal programming error".
2184 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2186 * gh_io.c (gh_write): New function.
2188 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
2189 throw.c (scm_internal_stack_catch): New sibling to the other catch
2190 functions. Code moved from gh_eval.c.
2191 throw.h: Added header.
2192 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
2193 scm_internal_stack_catch.
2195 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2197 * ioext.h: fix up prototypes.
2198 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
2199 Scheme name is now dup->fdes.
2200 (scm_dup_to_fdes): make the second argument optional and
2201 fold in the functionality of scm_primitive_dup.
2202 (scm_primitive_dup): deleted.
2204 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
2206 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
2207 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
2208 ultrix are defined. Use setvbuf instead of setbuf.
2209 (scm_setvbuf): new procedure.
2210 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
2211 (scm_setfileno): moved from ioext.c.
2212 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
2213 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.

2223 state as nested data while they are printed.
2224 (print_state_fluid, print_state_fluid_num): New variables.
2225 (scm_init_print): Initialize them.
2226 (scm_iprin): If print_state_fluid carries a print_state, use that
2227 instead of creating a new one.
2228 (scm_printer_apply, apply_stub, struct apply_data): New
2229 definitions to help with calling printer functions written in
2231 * print.h (scm_printer_apply): New prototype.
2233 * struct.c (scm_print_struct): Use scm_printer_apply to call the

2244 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
2245 SCM_ASSERT: arg comes before pos.
2247 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2249 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
2250 to a list of length zero correctly.
2252 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2254 Supply an `fgets' method for port objects to do fast line i/o.

2268 * ioext.h: removed scm_duplicate_port prototype.
2270 * ioext.c (scm_primitive_dup2): return the new file descriptor
2271 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
2273 (scm_fdopen): bug fix: don't try to make port unbuffered until its
2274 stream has been set.
2275 (scm_duplicate_port): deleted, there's now an implementation in
2277 (scm_primitive_dup2): do nothing if newfd == oldfd.
2279 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
2281 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the

2287 * fluids.c (next_fluid_num): don't do
2288 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
2290 * ports.h: prototypes too.
2291 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
2293 * fports.h: prototype too.
2294 * fports.c (scm_evict_ports): moved from ioext.c.
2296 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>

2301 * filesys.h: scm_close prototype.
2302 * filesys.c (scm_close): new procedure, can close file descriptors
2303 and ports (scsh compatible).
2305 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an

2321 (scm_make_root): Call scm_copy_fluids to make fluid bindings
2322 unique for the new root when it has a parent.
2324 * smob.h: Include "libguile/print.h" to make scm_print_state
2327 * dynl.c (free_dynl_obj): New function to free the dynamic object
2328 data. (dynl_smob): Use it.
2329 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
2330 the dynamic object data below the linking of the object to avoid
2331 memory leak when the linking code throws an error. Now the code
2332 leaks a whole dynamically linked library when must_malloc throws,
2333 but that should be much less likely.
2335 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
2337 Changes to compile under gnu-win32, from Marcus Daniels:
2338 * stime.c (tzset): If tzset isn't provided, make it a NOP.
2339 (scm_localtime): Change SCM_EOF to SCM_EOL.
2340 (scm_mktime): Likewise.
2341 * socket.c: Don't include sys/un.h unless autoconf tells
2342 us Unix domain sockets are available.

2344 (scm_addr_vector): Likewise.
2345 (scm_init_addr_buffer): Likewise.

2353 (scm_setpwent): For setpwent.
2354 (scm_setegid): For setegid.
2355 * net_db.c (scm_inet_netof): Don't include unless support

2371 scm_misc_error, not SCM_EOF.
2373 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of

2375 think this is left over from the (eq? '() #f) days.
2377 * read.c (recsexpr): Give this a dummy definition if
2378 DEBUG_EXTENSIONS isn't #defined.
2380 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
2382 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

2392 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
2393 alloca.lo will be included in @LIBLOBJS@. Something better than
2394 this should be possible.
2395 * Makefile.in: Regenerated.
2397 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
2399 * simpos.h: prototype for scm_primitive_exit.
2400 * simpos.c (scm_primitive_exit): new procedure, terminates the
2401 process without unwinding the stack.
2403 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
2405 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
2406 argument and logior its components together, so the user doesn't
2407 have to do this explicitly. Also, if regexp/basic is supplied, then
2408 turn off REG_EXTENDED.
2409 (scm_init_regex_posix): New regexp/basic symbol.
2410 (REG_BASIC): #define this if it is not already present.
2412 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

2426 * Makefile.in: Regenerated.
2428 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
2429 flag; I don't think we support it.
2430 (scm_make_regexp): Make sure the user doesn't pass the
2433 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
2435 (scm_init_regex_posix): Define constants for the REG_mumble flags;

2445 (versiondat.h): Print a message, but don't print all the commands.
2446 * load.c: #include "alist.h".
2447 (init_build_info): New function.
2448 (scm_init_load): Call it.

2451 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
2453 * root.c: Establish a reliable catch-all handler for the new root.
2454 After all the Scheme handler function might signal an error too,
2455 and we don't want to lose that.
2456 (cwdr_inner_body): Renamed from cwdr_body.
2457 (cwdr_outer_body): New function, to establish the user's handler,
2458 and pass control to cwdr_inner_body.
2459 (cwdr): Establish the reliable catch-all handler here, and pass
2460 control to cwdr_outer_body.
2461 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
2462 the user's handler through to cwdr_outer_body.

2468 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
2469 across this. Only works on GCC. Otherwise, we hope for the best.
2470 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
2471 the feeling that real thread systems will not need this...
2473 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
2475 Try to detect when people are using one version of libguile and a
2476 different version of ice-9. People have been skewing things and
2477 sending in bug reports.
2478 * Makefile.am (versiondat.h): New file to generate.
2479 * version.c: #include "versiondat.h", to get version info.
2480 (scm_libguile_config_stamp): New function.
2481 * script.c: #include "version.h".
2482 (scm_compile_switches): Call scm_version to get version number.
2483 * scmconfig.h.in, Makefile.in: Regenerated.
2484 * Makefile.in: Regenerated.
2486 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
2487 primitive definitions under their Scheme names.
2489 * Makefile.am (libguile_la_LDFLAGS): Update library version to
2490 1:2. Helps avoid confusion between installed and uninstalled libs.
2492 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
2495 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
2496 backslash from definition; this should be used like: GDB_INTERFACE;
2498 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2500 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
2501 new port unbuffered until its stream has been set.
2503 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2505 * ports.h: new prototype.
2506 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
2508 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
2510 Make things compile neatly under Sun's C compiler.
2511 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
2512 * extchrs.c (xmbtowc): Make the second arg a normal char, not
2513 unsigned, because that's what the ANSI function takes.
2514 * extchrs.h (xmbtowc): Corresponding change to prototype.
2515 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2517 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2518 argument plain char *.
2519 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2521 * tag.c (scm_tag): Remove unreachable statement.
2522 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2523 top of the word, it should be unsigned.
2525 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2526 is defined, to avoid warnings; it's only used in the
2527 conflict-checking code. Which might go away anyway.
2528 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2529 conditionals; put the label definition in an #if too, to stifle
2532 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2533 ChangeLog-threads in the distribution.
2534 * Makefile.in: Regenerated.
2536 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2538 * guile-snarf.in: Changed regexp to support CPPs that insert
2539 whitespace between lexical tokens (which munges the `%%%' snarf
2542 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2544 * load.c (scm_init_load_path): Append $(datadir)/guile to
2545 %load-path, so modules do not have to be installed in Guile's
2546 current version directory.
2548 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2550 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2551 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2552 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2553 call the sysdep functions with deferred ints.
2554 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2555 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2556 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2559 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2562 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2564 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2566 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2568 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2571 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2573 * eval.c (scm_lookupcar1): New procedure to cope with a race
2574 condition during lookup (when using threads).
2575 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2576 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2579 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2581 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2582 supplied. (Change from Tim Pierce.)
2584 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2586 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2587 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2588 default and not `()'. `#f' is the canonical non-value in Scheme,
2591 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2593 * struct.c (struct_printer): New variable that holds a handle on
2594 the Scheme variable *struct-printer*. This variable can be set by
2595 Scheme code to override the printing of structures.
2596 (scm_print_struct): If struct_printer is set, call it. If it is
2597 not set, or returns #f, print the structure in the old fashion.
2598 Include "eval.h" for scm_apply.
2600 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2602 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2603 scm_struct_i_n_words to get the number of fields, not
2604 -scm_struct_n_extra_words.
2606 On the route to fancier struct printing:
2607 * struct.c (scm_print_struct): New function to print a structure.
2608 Include "genio.h" to support it. This function doesn't do
2609 anything interesting right now, but I think it should be here
2611 * struct.h: Include "print.h" and add prototype for
2613 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2614 print structures ourself.
2616 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2618 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2619 before applying the handler in case it doesn't return.
2621 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2623 * scmsigs.h, async.h: updated.
2625 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2628 * posix.c (scm_uname): interpret only negative values as an error.
2629 Solaris normally returns a positive value.
2631 * script.c (scm_compile_shell_switches): if we are not going into
2632 an interactive repl, set scm_mask_ints to zero so that asyncs can
2635 * simpos.c (scm_system): don't ignore/unignore signals around
2638 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2641 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2642 done in boot-9.scm instead.
2644 * scmsigs.c, async.c: Major rewriting of signal handling code.
2645 (scm_sigaction): new procedure.
2646 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2648 (scm_raise): return unspecified, throw error on failure.
2650 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2652 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2653 feature, to help boot-9.scm decide whether to import the regex
2656 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2658 * eval.c: Include scmconfig.h at the beginning of the file so that
2659 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2662 * regex-posix.c: #include "_scm.h" before conditionally #including
2663 <regex.h>; the former defines HAVE_REGCOMP.
2665 * regex-posix.c: #include <regex.h> conditionally, so the file is
2666 CPP'able (for dependency scanning) even on systems that don't have
2669 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2671 Add new R4RS-compliant syntax for keywords.
2672 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2673 regardless of the setting of the `keywords' read option.
2674 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2675 can be re-read no matter what the setting of the `keywords' read
2678 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2680 Add support for POSIX regular expressions.
2682 * regex-posix.c, regex-posix.h: New files. (Some code
2683 is taken liberally from rx/rgx.c in the old Guile dist.)
2685 * init.c: Include regex-posix.h.
2686 (scm_boot_guile_1): Call scm_init_regex_posix.
2688 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2689 Add regex-posix.[ch] sources.
2690 * Makefile.in: Regenerated.
2692 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2693 to do this automatically? It didn't for me, bleh.)
2695 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2697 * fports.c (print_pipe_port): New function.
2698 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2699 latter doesn't even take the right arguments.
2701 * Makefile.am: Increment shared lib revision number. I think
2702 sometimes the uninstalled Guile finds the installed shared lib;
2703 Gord says doing this might help. As things turned out, I can't
2704 say whether it does.
2705 * Makefile.in: Regenerated.
2707 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2708 passing it as the closure argument to scm_boot_guile. (Bill
2711 * ports.c (print_void_port, putc_void_port, puts_void_port,
2712 write_void_port, flush_void_port, getc_void_port, close_void_port,
2713 noop0): Use ANSI prototypes instead of K&R declarations, so the
2714 initialization of void_port_ptob gets aggressively type-checked.
2715 Fix arguments of print_void_port and write_void_port. (Bill

2749 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2751 * script.c (scm_find_executable): Use prototype-style definition
2752 here; apparently it's not quite right to have const in a prototype
2753 and then use a K&R declaration. I wonder if stuff like this will
2754 go away if we compile with -Wrequire-prototypes, or whatever that
2755 is... (Bernard URBAN)
2757 * scmhob.h: New text from Bernard URBAN.
2759 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2761 * script.c: Don't #define const on hpux. Configure takes care of
2762 this. (Thanks to Larry Schwimmer.)
2764 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2765 decide whether to #include <unistd.h>, instead of listing a bunch
2766 of systems. Don't #include stdio twice. Removed dyked-out
2767 definition of scm_find_impl_file.
2769 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2771 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2772 library version info to 1:0.
2773 * Makefile.in: Regenerated.

2779 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2780 throw.c: Update copyright years; these files have been worked on
2781 significantly in 1997, but only had copyright years for 1996.
2782 Also, change name of copyright holder on some from Mikael
2783 Djurfeldt to Free Software Foundation; he has signed papers
2784 assigning the changes to the FSF.
2786 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2787 reason not to give the user the option.
2789 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2790 Return #f on end-of-file when scanning table (i.e. when called
2791 with no arguments). Try to catch errors, when we can.
2792 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2794 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2795 external declarations. These are useful.
2797 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2799 * posix.c: don't include <sys/select.h> or define macros for
2800 select, since they were not used in this file.
2802 * filesys.c (scm_select): make the fifth parameter microseconds,
2803 not milliseconds. let the fourth parameter be either a real value
2804 or an integer or #f. The first, second and third arguments can
2805 now be vectors: the type of the corresponding return set will be
2807 (set_element, get_element): new static procedures.
2809 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2811 * strports.c (scm_eval_string): New function.
2812 (scm_eval_0str): Trivially re-implemented in terms of
2814 * strports.h (scm_eval_string): New extern decl.
2816 * net_db.c (h_errno): Add extern decl for this.
2818 * fports.c (local_pclose): New function.
2819 (scm_pipob): Use it in the initializer here.
2822 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2823 Use a meaningful error message when signalling an error. For
2824 this, scm_gethost must check h_errno rather than errno.
2826 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2828 * Makefile.in: Regenerated, using automake-1.1p.
2830 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2832 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2833 not SCM_UNSPECIFIED.
2835 * script.c (scm_compile_shell_switches): don't append (quit) if
2837 (scm_shell): call scm_exit_status and exit on the result of the
2840 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2842 Ensure that shared substrings are handled properly when passed to
2843 a system call or other foreign function. Many thanks to Tim
2845 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2846 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2847 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2848 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

2860 SCM_COERCE_SUBSTR to make sure shared substrings are
2863 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2865 * error.c (scm_error): Add newline to error message.
2867 * init.c (scm_init_standard_ports): Doc fix.
2869 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2871 * dynl-shl.c: Completely replaced with new code from Bernard
2874 * script.c (scm_ice_9_already_loaded): New variable.
2875 (scm_compile_shell_switches): Use it.
2877 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2879 * filesys.c (scm_input_waiting_p): add missing third argument to
2882 * stime.c (scm_localtime): copy the result of localtime before
2883 calling gmtime in case they share a buffer.
2884 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2887 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2889 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2891 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2893 * Makefile.am (check-local): New target, which causes 'make check'
2894 to run gh_test_c and gh_test_repl, with some trivial input.
2895 * Makefile.in: Rgnrtd.
2897 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2899 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2902 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2904 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2905 sure how this was supposed to work.
2906 (scm_async_click): don't send SCM_TICK_SIGNAL.
2907 (scm_init_async): don't initialize %tick-thunk.
2909 * the following change doesn't affect the Scheme interface:
2910 gc-thunk is called at the end of garbage collection. however it's
2911 no longer implemented by pretending it's a signal.
2913 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2914 system async corresponding to scm_gc_thunk.
2915 * async.h: declare scm_gc_async.
2916 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2917 gc-thunk directly, instead of going through a signal handler.
2918 (scm_gc_async): new variable, points to the GC system-async.
2919 (scm_init_async): save the GC async as scm_gc_async instead
2920 of using system_signal_asyncs.
2921 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2923 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2925 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2926 Don't screw up if we're interrupted.
2927 * Makefile.in: Regeneradet.
2929 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2931 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2933 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2934 we're not using AM_INIT_GUILE_MODULE any more.
2935 * Makefile.in: Reneregated.
2937 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2939 Functions for finding variable bindings, grace à Tim Pierce.
2940 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2941 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2943 Get 'make dist' to work again.
2944 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2945 * Makefile.in: Regenerated, like a surry without a fringe on top.
2947 Changes for reduced Guile distribution: one configure script,
2949 * configure.in, configure: Removed.
2950 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2951 real configure script lives.
2952 * Makefile.in, scmconfig.h.in: Regenerated.
2954 * init.c: #include "script.h", to get prototype for script.c's
2957 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2959 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2960 scm_must_malloc, not raw malloc.
2962 * script.c (scm_compile_shell_switches): Dyke out debugging output
2965 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2967 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2969 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2970 system has them. Hope this is safe. Previously
2971 sys/timeb.h was included if HAVE_FTIME was defined or if
2972 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2973 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2975 * ioext.c (scm_setfileno): add missing third argument to
2976 scm_misc_error call.
2978 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2980 * eq.c (scm_equal_p): Correctly compare strings of different
2981 varieties. (Thanks to Tim Pierce.)
2983 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2985 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2986 #! block comment must occur on a line all by itself.
2988 Move most of the guts of shell command processing into libguile,
2989 so guile.c can be very small (and eventuallly auto-generated. (I
2990 mean, generated mechanically, not self-generated. Hmm.))
2991 * guile.c, script.c, script.h: New source files.
2992 * init.c (scm_boot_guile_1): Call scm_init_script.
2993 * libguile.h: #include "script.h".
2994 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2995 targets, for new executable.
2996 (libguile_la_SOURCES): Mention script.c.
2997 (modinclude_HEADERS): Add script.h.
2998 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2999 not dynamic linking is enabled. This is because we're generating
3000 executables now. Move CY_AC_WITH_THREADS call after those, so the
3001 values of cy_cv_threads_libs captures the libs chosen above.
3002 * Makefile.in, configure, aclocal.m4: Regenerated.
3004 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
3005 We don't maintain this interface any more, and it just confuses
3008 * alloca.c: #include <scmconfig.h>, not <config.h>.
3009 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
3010 it'll get included in disties.
3012 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
3014 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
3015 be distributed, because they confuse people.
3016 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
3018 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
3020 * configure.in: check for presence of gethostent (not present on
3021 OpenBSD by default).
3022 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
3023 * configure, scmconfig.h.in: Regenerated.
3025 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
3027 * backtrace.c (scm_backtrace): Split message string across
3028 newlines properly. GCC is more tolerant of this than other
3031 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
3033 Merge threads directory into libguile.
3034 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
3035 threads.h: New source files.

3037 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
3039 (modinclude_HEADERS): Add threads.h, coop-defs.h.
3040 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
3041 coop-threads.c.cygnus, coop-threads.h.cygnus.
3042 * configure.in: If we're using threads, include threads.o in
3044 * _scm.h, libguile.h: threads.h lives in this directory now.
3045 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
3046 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
3047 currently used, but brought along for information's sake.
3048 * ChangeLog-threads: log from old 'threads' directory.
3049 * Makefile.in, configure: Rebuilt.
3051 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
3053 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
3056 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
3058 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
3060 Merge GH interface library into libguile.
3061 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
3062 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
3063 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
3064 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
3066 (EXTRA_libguile_la_SOURCES): ... here.
3067 (pkginclude_HEADERS): Add variable, to get gh.h installed.
3068 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
3069 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
3070 New variables, describing how to build the gh test programs.
3071 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
3072 build the test programs, and we probably should have been linking
3073 libguile.la against them all along, to support AIX shared libs.
3074 Add cflags for threads to CFLAGS; add libs for threads to new
3075 variable THREAD_LIBS, used in Makefile.am.
3076 * ChangeLog-gh: log from old `gh' subdirectory.
3077 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
3079 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
3081 * acconfig.h: Undo change of Apr 9; including the definition of
3082 PACKAGE in the guile headers conflicts with applications' own
3084 * scmconfig.h.in: Regenerated.
3086 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

3093 when PROC is receiving no arguments.
3095 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
3097 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
3098 have S_IFSOCK. This is the case under Ultrix.
3100 * posix.c (scm_status_exit_val, scm_status_exit_val,
3101 scm_status_term_sig, scm_status_stop_sig): Modified to work with
3102 Ultrix versions of WIFSTOPPED, etc., which assume that their
3103 arguments are lvalues (hmm).
3105 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
3107 * eval.c: Doc fixes.
3109 * throw.c: Doc fixes; rearranged.
3111 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
3113 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
3115 * acconfig.h: Added entry for PACKAGE.
3116 * scmconfig.h.in: Regenerated.
3118 Changes to work with automake-1.1n, which has better libtool support.
3119 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
3120 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
3122 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
3124 * Makefile.in: Rebuild.
3126 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3128 * stime.c (scm_mktime): take an optional zone argument.
3129 (scm_localtime): check putenv return value.
3130 (scm_strftime, scm_strptime): moved from posix.c. move #include
3132 stime.h, posix.h: update prototypes.
3133 (bdtime2c, setzone, restorezone): new static procedures.
3134 (scm_mktime, scm_strftime): use them.
3135 (scm_strftime): don't call mktime before strftime. Use
3136 filltime for return value.
3137 (filltime): convert NULL zname to #f.
3138 (scm_strptime): return a count of characters consumed, not
3139 the remaining string.
3141 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3143 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
3144 (scm_mktime): likewise.
3146 Uncomment localtime and mktime.
3148 * configure.in: add AC_STRUCT_TIMEZONE.
3150 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3152 * stime.c (scm_init_stime): don't define ticks/sec.
3153 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
3154 return value problem and is still portable.)
3156 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3158 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
3159 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
3160 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
3161 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
3162 cpp_err_symbols.c): Corresponding changes.
3163 * Makefile.in: Regenerated.
3165 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3167 * posix.c (scm_putenv): don't check HAVE_PUTENV.
3168 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
3169 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
3170 * putenv.c: new file, from sh-utils 1.12.
3172 * posix.c (scm_environ): use malloc in place of scm_must_malloc
3173 since allocation isn't for Scheme objects.
3174 (scm_putenv): copy strings before placing in the environment.
3176 * stime.c (scm_current_time): throw an error if time returns -1,
3177 instead of returning #f.
3178 (scm_get_internal_real_time, scm_get_internal_real_time): use
3179 scm_long2num for return value instead of SCM_MAKINUM.
3181 * stime.h: prototypes updated.
3183 * stime.c (scm_time_in_msec): apparently unused, deleted.
3185 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
3187 * configure.in: check for gettimeofday.
3189 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
3190 which may be more usefully portable than a gettimeofday interface.
3192 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
3194 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
3196 * Makefile.in: Regenerated.
3198 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3200 * stime.c (filltime): recovered static procedure.
3201 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
3204 * posix.h: add prototype for scm_close_pipe, remove prototypes for
3205 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
3207 * posix.c (scm_mknod): split the mode argument into type and perms
3208 arguments, like the extra fields returned by stat.
3210 * fports.c (scm_pipob): set the close, free and print procedures.
3211 (scm_close_pipe): new procedure.
3213 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
3214 define them in boot-9.scm
3216 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3218 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
3219 wan't defined. Don't include fd.h.
3221 * Previously fd.h was regenerated whenever configure was run,
3222 forcing a couple of files to be recompiled.
3224 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
3225 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
3226 Check for _fileno as well as _file.
3228 * ioext.c: don't fd.h.
3229 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
3232 * Change the stratigy for getting information about errno
3233 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
3234 generating lists of symbols during the build process, which will
3235 not always work, include comprehensive lists in the distribution.
3236 To help keep the lists up to date, the "check_signals" and
3237 "check_errnos" make targets can be used.
3239 * configure.in: don't check for a command to extract errno codes.
3240 * Makefile.am: update file lists, remove errnos.list and errnos.c
3241 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
3242 check_errnos targets.
3243 (CLEANFILES): remove errnos.c and errnos.list, add
3244 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
3245 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
3246 * errnos.default: deleted.
3247 * cpp_signal.c: new file.
3248 * cpp_errno.c: renamed from errnos_get.c.
3249 * cpp_err_symbols, cpp_sig_symbols: new files.
3250 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
3251 * error.c (scm_init_error): #include cpp_err_symbols instead of
3253 * posix.c (scm_init_posix): don't intern signal symbols. #include
3256 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
3258 * strop.c (scm_i_index): allow the lower bound to be equal to the
3259 length of the string, so a null string doesn't always give an error.
3261 * posix.h: new prototypes.
3262 * posix.c (scm_status_exit_val, scm_status_term_sig,
3263 scm_status_stop_sig): new functions, as in scsh. They break down
3264 process status values as returned by waitpid.
3266 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
3268 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
3269 configure doesn't know about it.
3271 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3273 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
3275 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
3276 which defines C variables with global linkage.
3278 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3280 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
3283 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
3285 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
3286 has time to check why this doesn't work well with continuations.
3288 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
3290 * Fix shell syntax error; some shells won't tolerate
3291 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
3293 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3295 * posix.c (scm_uname): throw an error if uname fails instead
3298 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
3300 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
3303 * async.c (scm_ints_disabled): definition moved from error.c.
3305 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3307 * acconfig.h: Removed PACKAGE.
3309 * scmconfig.h.in: Regenerated.
3311 * snarf.h: g++ says it's non-portable not to specify the first
3312 argument in a varargs declaration. I introduced the first
3313 argument by using preprocessor conditionals.
3315 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
3317 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
3318 (scm_freopen): use RO string macros for filename and modes.
3319 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
3321 * posix.c (scm_getgrgid): simplify conversion of name to C string.
3322 (scm_mknod): use RO string macros for path.
3324 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
3325 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
3327 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
3328 use SCM_ROSTRINGP and SCM_ROCHARS.

3332 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
3335 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,

3337 support for byte vectors.
3339 * print.c (scm_iprin1): Limit number of vector elements printed
3340 according to pstate->length.
3342 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3344 * backtrace.c (scm_display_error_message): don't segv if message
3347 * error.h: prototype for scm_error_scm.
3349 * error.c (scm_error_scm): new procedure, reimplements scm-error
3350 in C and uses scm_error.
3352 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3354 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
3355 pointer to the Scheme variable read-hash-procedures and intern it
3356 in scm_init_read. Modify scm_read_hash_extend and
3357 scm_get_hash_procedure to use the pointer.
3359 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3361 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
3362 (SCM_KEYWORD_STYLE): defined.
3364 * read.c (scm_read_opts): add a keywords option. This isn't a
3365 boolean option, in case someone wants to add support for DSSSL
3367 Setup scm_keyword_prefix symbol.
3368 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
3370 I've left keyword support disabled by default, since it doesn't
3371 seem to break the module system and it gives R4RS standard behaviour.
3372 It can be reactivated with (read-set! keywords 'prefix).
3374 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3376 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
3377 before constructing arbiter.
3379 * eval.c (scm_m_define): Bugfix: Check that the object is a
3380 closure before setting the procedure property!
3382 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
3384 * ports.c: Removed `ungetc-char-ready?'.
3386 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
3388 * read.c (scm_init_read): intitialise scm_read_hash_procedures
3389 (idea from Mikael: make it a pair so scm_permanent object only
3391 (scm_read_hash_extend): don't call scm_permanent_object.
3392 (ideas from Mikael): if chr is already in the list, replace its
3393 procedure instead of appending it again. If proc is #f, remove
3395 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
3397 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
3399 * gdbint.c (gdb_read): update scm_lreadr usage.

3403 * load.c (scm_primitive_load, scm_read_and_eval_x,
3404 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
3406 * read.h: add prototype for scm_read_hash_extend. Change args for
3409 * read.c (scm_read_hash_procedures): new variable.
3410 (scm_read_hash_extend): new procedure.
3411 (scm_get_hash_procedure): new procedure.
3412 (scm_lreadr): use scm_get_hash_procedure instead of an argument
3413 for extended # processing.
3414 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
3415 scm_read_token): remove case_i, sharp arguments. Change callers.
3417 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
3419 * read.h (SCM_N_READ_OPTIONS): increase to 3.
3420 (SCM_CASE_INSENSITIVE_P): define.
3422 * read.c: add case-insensitive option to scm_read_opts.
3423 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
3424 to determine whether to convert symbol case.
3425 (default_case_i): definition removed.
3426 * read.c (scm_read_token): if case_i, downcase ic before doing
3429 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3431 * configure.in: Added configuration option `guile-debug'.
3432 Configure with --enable-guile-debug if you want a bunch of extra
3433 functions used for debugging when developing Guile.
3435 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
3437 * procs.c (make-cclo): New undocumented debugging procedure: Make
3438 compiled closure with internal procedure PROC and length LENGTH.
3439 Only compiled if GUILE_DEBUG is defined.
3441 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
3443 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
3445 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
3447 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
3448 with 3 or more args internally to the evaluator.
3450 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3452 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
3453 with 3 or more args internally to the evaluator. This is mainly
3454 because we don't want to pass entry and exit points of the
3455 debug support twice, but it also seems to increase the speed of
3456 the evaluator for such calls (e. g. (+ 1 2 3)).
3458 * backtrace.c (scm_display_application): New procedure:
3459 display-application; Set fancy printing parameters individually
3460 for different types of display (backtrace, error, application).
3461 (These should of course be customizable!)
3463 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
3464 clear the CHECK-flags.
3466 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3468 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
3470 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3472 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
3473 from pairs with a GLOC in the car.
3475 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
3476 otherwise `symbol-hash' will behave badly.
3477 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
3478 we get segmentation fault!
3480 * symbols.c: Added #include "weaks.h". New functions:
3481 `builtin-bindings' and `builtin-weak-bindings'. (These will be
3482 moved to an extraneous library when we split libguile.)
3484 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3486 * filesys.c (scm_stat): stat now takes fport arguments too as
3487 documented in the manual.
3489 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3491 * debug.c (scm_single_step): Bugfix: Call continuation with
3492 scm_call_continuation instead of throwing to it.
3494 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3496 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
3497 argument wasn't declared to be optional.
3499 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3501 * stime.c (scm_init_stime): Add feature "current-time".
3503 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3505 * throw.h: prototype for scm_exit_status.
3506 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3507 args to derive an exit status. Allows (quit) to work from a
3509 (scm_exit_status): new function.
3512 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3514 * eval.c (scm_deval): Removed some old code.
3515 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3517 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3520 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3523 * procs.c: Introduce the existent C function scm_thunk_p at the
3524 Scheme level as well.
3526 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3528 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3529 used from C to easily lookup the value of a symbol in the current
3532 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3534 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3535 scm_init_unif in this file. This will also fix a previous problem
3538 * configure.in: Added AM_MAINTAINER_MODE
3540 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3542 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3545 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3547 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3548 source files that are not always included in libguile but should
3549 have their dependencies calculated by automake. This variable is
3550 recognized by automake, no further magic is needed.
3551 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3552 to deal exclusively with *.lo files, as it seems. The *.o files
3553 are built automatically when the corresponding *.lo file gets
3556 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3558 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3561 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3563 * unif.c (scm_array_set_x): minor change to argument error checking.
3565 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3567 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3568 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3569 They should only be included in the library at configure.in's
3571 (libguile_la_LDADD): Include the appropriate .lo files here.
3572 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3573 so we know when to build them (and their .lo bretheren).
3574 * configure.in (LIBLOBJS): New substituted variable. We let
3575 configure decide which .o files to include in LIBOBJS, and then
3576 put the corresponding list of .lo files in LIBLOBJS. The latter
3577 is what we pass to libtool.
3578 * Makefile.in, configure: regenerated.
3580 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3582 * symbols.c (scm_sysintern0): New function. Contains the core of
3583 old scm_sysintern but doesn't take a second value argument.
3584 (scm_sysintern): Now uses scm_sysintern0.
3585 (scm_sysintern_no_module_lookup): Renamed to
3586 scm_sysintern0_no_module_lookup and doesn't take a second value
3587 argument any longer.
3589 * symbols.h (scm_sysintern0: Added declaration.
3591 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3592 scm_sysintern when interning option keys. Otherwise we risk
3593 destroying the values of already interned variables.
3595 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3596 scheme-level boolean (use SCM_NFALSEP).
3598 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3600 (scm_backtrace): New function. (C version of old function from
3601 boot-9.scm) Motivation: Make it possible to display backtraces
3602 without depending on boot-9.scm. (I'm uncertain if this
3603 motivation is good enough...)
3605 * root.h (scm_root_state): Add member the_last_stack_var.
3606 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3608 * root.c (mark_root): Mark scm_the_last_stack_var.
3610 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3613 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3615 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3616 1. mark_lazy_catch didn't mark the smob.
3617 2. Both functions above have standard variants:
3618 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3619 free_lazy_catch --> scm_free0.
3621 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3623 * throw.c (scm_internal_lazy_catch): New function.
3624 (scm_lazy_catch): Rewritten to use it.
3625 (scm_ithrow): Handle the new lazy catch representation.
3626 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3627 that doesn't have a jmpbuf is a lazy catch clause.
3628 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3629 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3630 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3632 (scm_init_throw): Register the new lazy-catch smob type.
3633 * throw.h (scm_internal_lazy_catch): decl for new function.
3635 * throw.c (scm_internal_catch): Doc fixes.
3637 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3638 configure.in. Including this might cause problems if applications
3639 that link against libguile include their own copies of alloca, but
3640 if they're using autoconf, they should be adding libguile to LIBS
3641 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3642 the copy in libguile, and things will be okay. (I think.)
3644 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3646 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3648 strop.h: move prototypes too.
3650 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3652 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3655 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3656 etc. I deleted them from filesys.c long ago, but didn't
3657 notice they were here too (although ineffective since
3658 sys/stat.h wasn't included).
3660 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3662 * eval.c: Don't define alloca in GCC case. gcc will automatically
3663 use __builtin_alloca if appropriate.
3665 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3667 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3668 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3669 that values of automatic variables are preserved. See comments
3670 for safe_setjmp for details.
3672 Change from Thomas Morgan:
3673 * variable.c: Include eq.h.
3674 (var_equal): New function.
3675 (variable_smob): Use var_equal as the discriminator for variables.
3677 * throw.c (s_throw): Remove extraneous declaration.
3679 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3680 * eval.c: Add necessary CPP cruft to support that.
3681 * configure, Makefile.in, scmconfig.h.in: regenerated.
3683 Change from Thomas Morgan:
3684 * procprop.c (scm_procedure_properties): Convert the Scheme
3685 boolean returned by scm_procedure_p into a C boolean before using
3686 it as a condition for SCM_ASSERT.
3687 (scm_procedure_property): Likewise.
3689 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3690 indications of Unixness.
3693 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3695 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3697 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3699 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3700 "unknown # object" error messages.
3702 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3703 (scm_i_index) and declare it static. Add a 'direction' argument
3704 to indicate what way the search should go.
3705 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3707 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3708 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3710 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3712 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3714 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3715 to avoid clash with various scsh forks.
3717 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3719 The following two changes (ramap.c, throw.c) are motivated by the
3720 apparent unportability of forward declarations of static arrays of
3721 the form `static foo bar[];'.
3723 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3724 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3726 * throw.c (scm_throw): Moved above scm_ithrow.
3728 * options.h: Removed the extern declarations of scm_yes_sym and
3729 scm_no_sym since these are static.
3731 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3733 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3735 * Makefile.am: remove AWK=@AWK@.
3736 Add a rule for generating errnos.list.
3737 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3739 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3740 don't extract errnos, just set a variable (avoids the
3741 need to recompile error.c just because configure is run.)
3743 * unif.h: update prototypes.
3744 * unif.c (scm_uniform_array_read,write): change the offset and
3745 length arguments to start and end, for consistency.
3747 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3749 * ioext.h: update prototypes.
3750 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3751 scm_read_line_x, it's a more general procedure using an
3752 interface from scsh. read-line and read-line! are now defined
3754 Note that the new read-line trims the terminator
3755 by default, previously it was appended to the returned string. An
3756 optional argument specifies how to process the terminator (scsh
3757 compatible). For the old behaviour: (read-line port 'concat).
3758 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3759 returns a pair, but is converted to multiple values if the scsh
3762 socket.h: update prototypes.
3763 * socket.c (scm_recvfrom): for consistency with other procedures,
3764 take start and end as separate optional arguments.
3765 (scm_recv, scm_recvfrom): don't allow the second argument
3766 to be a size, only a buffer. Change the scheme names to
3767 recv! and recvfrom!. Don't return the buffer.
3769 * ioext.h, posix.h: move prototypes too.
3770 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3771 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3772 "read.h" and "unif.h".
3773 * ioext.c: include "chars.h"
3775 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3777 * dynl.c: The dynamic linking and module registration functions
3778 are now defined even when dynamic linking is not available for the
3779 host system. Some of their functionality can be done without
3780 dynamic linking; when it's really needed, they throw errors.
3782 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3784 * configure.in: Only define DYNAMIC_LINKING when one of the system
3785 dependent functions is detected.
3786 * dynl.c (scm_dynamic_func): New function to get the address of a
3787 function in a dynamic object.
3788 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3789 produced by scm_dynamic_func as the thing to call.
3791 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3793 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3794 (scm_register_module_xxx, scm_registered_modules,
3795 scm_clear_registered_modules): New functions.
3797 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3799 * symbols.c (scm_sysintern): Renamed to
3800 scm_sysintern_no_module_lookup.
3801 (scm_sysintern): New function to take the place of the old
3802 scm_sysintern. It uses the current toplevel lookup closure to give
3803 the symbol its value. This is a temporary hack to put packages
3804 like gtcltk into their own module.
3805 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3806 us whether `scm_top_level_lookup_closure_var' has been initialized
3808 * eval.c (scm_init_eval): Set it.
3810 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3812 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3813 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3815 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3817 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3818 scm_sys_dup): deleted: FD capability will be added to other
3820 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3821 scm_fd_free, fd_smob, scm_intern_fd.
3822 (scm_open): renamed from scm_sys_open. Return a port instead of
3823 an FD object. Make the mode argument optional.
3824 (scm_sys_create): deleted, it's just a special case of open.
3825 (scm_init_filesys): move interning of constants O_CREAT etc.,
3826 here (were previously using SCM_CONST_LONG macro).
3827 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3829 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3830 include "fports.h" and <stdio.h>
3831 (scm_stat, scm_select): don't support FD objects.
3833 * error.h: adjust scm_syserror_msg prototype.
3834 * error.c (scm_syserror_msg): take an extra argument for errno.
3835 Using the global value didn't always work, since it could be
3836 reset by procedure calls in the message or args arguments.
3838 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3839 I don't understand why the check was there (and what about the
3842 * strop.c (scm_string_copy): allow shared substrings to be copied.
3844 * unif.h: corresponding change to prototypes.
3845 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3846 recognize two new optional arguments: offset and length. Allow
3847 the port argument to be an integer (file descriptor, for scsh).
3848 Include <unistd.h> for "read" prototype.
3850 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3852 * socket.c: don't include filesys.h.
3854 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3856 * Makefile.am: add AWK=@AWK@ (?)
3858 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3860 Add a rule to generate errnos.c from errnos.
3861 * error.c (scm_init_error): include errnos.c.
3862 * errnos_cnvt.awk: new file, converts the list of errno codes to
3864 * errnos_get.c: new file.
3865 * errnos.default: new file, contains errnos to try if they can't
3866 be extracted from errno.h.
3867 * configure.in: if using GCC, try and extract errno codes from
3871 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3873 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3874 * Makefile.am: Made libguile into a libtool library.
3875 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3876 Set libtool_libs to indicate that libguile is a libtool library.
3877 See guile/ChangeLog for details.
3878 * .cvsignore: ignore "*.lo", the libtool library objects.
3880 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3882 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3883 use htons in getservbyport argument.
3885 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3887 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3888 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3891 * objprop.c (scm_object_property): No need to take the CDR of the
3892 value returned by scm_object_properties, since Aug 20 change.
3894 * configure.in: When checking for struct linger, #include
3895 <sys/types.h> as well as <sys/socket.h>. I've never known
3896 <sys/types.h> to cause any portability problems, and Solaris's
3897 <sys/socket.h> needs it.
3898 * configure: Rebuilt.
3900 I think the Sun compiler has chosen a perverse way to interpret
3901 ANSI declarations combined with K&R definitions. We'll
3902 appease it a little bit. But when it invades France, we fight.
3903 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3904 * print.h (scm_iprlist): Here too.
3905 * numbers.c (scm_divbigdig): Change definition to match
3906 declaration in numbers.h.
3907 * unif.c (scm_makflo): Change definition to match declaration in
3910 * init.c (scm_boot_guile): Don't return the value of
3911 scm_boot_guile_1. This function doesn't return a value;
3912 scm_boot_guile_1 doesn't return a value (or return at all).
3914 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3917 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3918 compile. I have a feeling this function is a bad idea anyway ---
3919 one should always test for features, not systems.
3921 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3922 semicolons. Only pure luck kept this from being noticed earlier.
3924 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3926 * socket.c (scm_recvfrom): Added missing semicolon.
3928 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3930 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3931 the buffer and start and end positions for scsh networking
3934 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3936 * configure.in: Revert previous change to this file; the problem
3937 is due to transient automake weirdness.
3938 * configure: Rebuilt.
3940 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3941 PLUGIN/guile.libs. configure generates the latter from the former.
3942 * Makefile.in: Rebuilt.
3944 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3945 need this if we install scripts, like guile-snarf.
3946 * configure: Rebuilt.
3948 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3950 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3952 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3954 * socket.c (scm_addr_vector): fix faulty scm_listify.
3956 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3958 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3959 style block comment is no longer considered an error.
3961 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3963 * PLUGIN/guile.libs.in: New file.
3964 * PLUGIN/guile.libs: Removed from repository.
3965 * configure.in: Create PLUGIN/guile.libs from
3966 PLUGIN/guile.libs.in. This is for including additonal libraries
3967 needed for dynamic linking.
3968 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3969 instead of PLUGIN/guile.libs.
3971 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3973 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3975 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3976 occurrences of the given element from the list, not just the
3977 first. This is how the Emacs Lisp functions behave, how the
3978 analogous Common Lisp functions behave, and (I believe) how the
3979 older Maclisp functions worked. I realize that this change may
3980 break code, but it seemed better to break it before the Guile
3983 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3984 Their prototypes were already present in gc.h, but they weren't
3986 (scm_init_storage): Initialize scm_protects.
3987 * root.c (scm_protects): New element of scm_sys_protects.
3989 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3991 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3993 * libguile.h: Added #include "libguile/net_db.h".
3995 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3996 30 change. That file is only meant for communication between the
3997 configuration process and load.c. If code linked against libguile
3998 wants to get at the paths mentioned in libpath.h, it can call
3999 functions declared in load.h.
4001 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4003 * libguile.h: Removed #include "libguile/fdsocket.h"
4005 * net_db.c: Added #include <sys/socket.h>.
4007 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
4009 * filesys.c (scm_input_waiting_p): use select in preference to
4010 FIONREAD, since the latter doesn't detect EOF.
4011 Throw error if neither select nor FIONREAD available.
4013 * socket.c (scm_connect): take a port, not a fd object.
4014 (scm_fill_sockaddr): throw an error if fam is not recognised.
4015 (scm_bind): use scm_fill_sockaddr.
4016 (scm_listen): take a port, not a fd object.
4017 (scm_accept): take and return a port. return #f in the car if
4018 address can't be got
4019 (scm_sock_fd_to_port): new procedure.
4020 (scm_socket): use scm_sock_fd_to_port.
4021 (scm_addr_vector): throw error if unrecognised address type.
4022 take an extra argument with the calling procedure name.
4023 (scm_getsockname): take a port. return #f if address can't be got.
4024 (scm_getpeername): take a port. return #f if address can't be got.
4025 (scm_recvfrom): take a port. return #f for address component if can't
4027 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
4028 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
4030 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
4032 * throw.c (scm_internal_catch): Make body funcs and handler funcs
4033 use separate data pointers, to allow them to be designed
4034 independently and reused.
4035 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
4036 Renamed from catch_body, catch_handler, and uncaught_throw; made
4038 (struct scm_catch_body_data): Renamed from catch_body_data; moved
4040 (scm_catch): Use the above.
4041 (scm_throw): Don't bother printing a message for an uncaught
4042 throw; we establish a default handler in init.
4043 * throw.h (scm_internal_catch): Prototype updated.
4044 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
4046 (struct scm_body_thunk_data): New structure, used as data
4047 argument to scm_body_thunk.
4048 * init.c (struct main_func_closure): New structure, packaging up
4049 the data to pass to the user's main function.
4050 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
4051 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
4052 scm_internal_catch to establish a catch-all handler, using
4053 scm_handle_by_message. This replaces the special-case code in
4055 (invoke_main_func): Body function for scm_internal_catch; invoke
4056 the user's main function, using the main_func_closure pointer to
4057 decide what to pass it.
4058 * root.c (struct cwdr_body_data): Remove handler_proc member.
4059 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
4060 (cwdr_handler): Removed.
4062 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4064 * socket.h (SCM_P): update bind prototype.
4065 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
4066 include "feature.h".
4067 (scm_socket): return a port, not a file descriptor object.
4068 include "fports.h" and <unistd.h>
4069 (scm_bind): take a port, not a file descriptor object.
4070 take an extra argument for address args.
4072 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
4073 INADDR_NONE, INADDR_LOOPBACK.
4075 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
4077 * init.c: include net_db.h and not fdsocket.h.
4078 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
4080 * Makefile.am: corresponding changes.
4081 * socket.h: renamed from fdsocket.h, fix names.
4082 * net_db.h: renamed from socket.h, fix names.
4083 * socket.c: renamed from fdsocket.c.
4084 remove _sys from procedure names.
4085 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
4086 add "socket" to features list.
4087 * net_db.c: renamed from socket.c.
4088 remove _sys from procedure names.
4089 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
4090 add "net-db" to features list.
4091 include "net_db.h". don't include <sys/socket.h> or
4094 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4096 * tags.h (scm_tags): Removed comma at end of last enumerator.
4098 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
4100 Don't use GCC extensions to allocate space for debugging frames.
4101 (Here he goes again! Why do we put up with this?!)
4102 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
4103 an scm_debug_info structure, not an in-line array of them. Add
4104 'info' member, to say how many vect elements we've used, for eval
4106 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
4107 a new variable debug_info_end to mark the end of vect, instead of
4108 the address of the 'info' pointer itself.
4109 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
4110 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
4111 (SCM_APPLY): Explicitly allocate space for debug.vect.
4112 * debug.c (scm_m_start_stack): Same, for vframe.vect.
4113 * stacks.c: Adjusted for new debug frame structure.
4114 (RELOC_INFO, RELOC_FRAME): New macros.
4115 (stack_depth, read_frames): Use them, and new scm_debug_frame
4116 element 'info', instead of magically knowing that eval frames have
4117 an info pointer sitting after vect.
4118 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
4120 (scm_init_stacks): Formatting tweaks.
4122 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
4124 Give GCC more control flow information, so it can be sure that
4125 variables aren't used uninitialized.
4126 * error.h (scm_error, scm_syserror, scm_syserror_msg,
4127 scm_sysmissing, scm_num_overflow, scm_out_of_range,
4128 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
4129 scm_misc_error): Tell GCC that these functions never return.
4130 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
4131 out the field type, call abort if SCM_ASSERT returns, to placate
4133 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
4134 scm_wta ever returns. We can't handle this case anyway, and this
4135 gives the optimizer more information.
4136 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
4137 scm_wta ever returns.
4139 In some cases, the code is fine, but GCC isn't smart enough to
4140 figure that out; this usually happens when one variable is only
4141 initialized and used when a particular condition holds true, and
4142 we know that condition will never change within a given invocation
4143 of the function. In this case, we simply initialize the variables
4144 to placate the compiler, hopefully to a value which will cause a
4145 crash if it is ever actually used.
4146 * print.c (scm_iprin1): Initialize mw_pos.
4147 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
4148 * throw.c (scm_ithrow): Initialize dynpair.
4149 * unif.c (scm_uniform_vector_ref): Initialize cra.
4150 * struct.c (init_struct): Initialize prot.
4151 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
4153 * strports.c (scm_eval_0str): Don't return uninitialized garbage
4154 if EXPR contains no expressions.
4156 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
4158 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
4159 cause an infinite loop (???). So much for the algebraic
4160 equivalency of variable-sized arrays and alloca...
4162 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
4164 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
4165 a SCM boolean, not a C boolean.
4167 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
4169 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
4170 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
4171 rules for raising scm_mtrigger. Previously, unfortunate but not
4172 unlikely circumstances could result in almost constant invokation
4173 of the gc. Now, this situations should be less likely, but they
4174 are not prevented completely.
4176 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
4178 * numbers.c (scm_fuck): Procedure removed; looks like old test
4180 * numbers.h: Prototype removed.
4182 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
4184 * debug.h (scm_debug_frame): Change `vect' member from an in-line
4185 array to a pointer, to match my Nov 21 change in eval.c.
4187 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4189 * libguile.h: Added #include "libguile/backtrace.h", #include
4190 "libguile/stacks.h".
4192 * strings.c (scm_string scm_make_string scm_string_ref
4193 scm_string_set_x scm_string_equal_p scm_string_append):
4194 Bugfix according to scm patch from Aubrey Jaffer:
4195 Corrected long-standing
4196 (not (eqv? (integer->char 128)
4197 (string-ref (make-string 1 (integer->char 128)) 0)))
4198 bug found by John Kozak <jk@noontide.demon.co.uk>.
4200 * strports.c, strports.h: Make scm_eval_0str return the value of
4201 the last expression evaluated (previously, it returned void).
4203 * strports.c, strports.h: New function: scm_read_0str. Does what
4206 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4208 * simpos.c (scm_getenv): return #f if string can't be found in the
4209 environment instead of throwing an exception, for compatibility
4210 with numerous other systems.
4212 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
4214 * Makefile.am (.c.x): Use guile-snarf.
4215 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
4217 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
4219 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4221 * backtrace.c (scm_display_error_message): Made non-static, and
4222 renamed from display_error_message.
4223 * backtrace.h (scm_display_error_message): Added extern decl.
4224 * throw.c (uncaught_throw): Use it to display the error message.
4226 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
4228 * inet_aton.c: Use #if 0, not #ifdef 0.
4230 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
4232 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
4233 to convert the returned value.
4234 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
4235 the offset argument.
4237 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
4239 Add new interface to catch/throw, usable from C as well as
4241 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
4242 (scm_internal_catch): New function, replaces...
4243 (scm_catch_apply): Deleted.
4244 * throw.c (scm_catch_apply): Deleted; replaced with a more general
4245 mechanism which is a bit more code, but can be used nicely from C
4246 and implement the Scheme semantics as well.
4247 (scm_internal_catch): This is the replacement; it's named after
4248 the analogous function in Emacs.
4249 (scm_catch): Reimplemented in terms of the above.
4250 (struct catch_body_data, catch_body, catch_handler): New
4251 functions, used by scm_catch.
4252 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
4253 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
4254 support for new cwdr.
4256 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
4259 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
4261 * acconfig.h: Added DYNAMIC_LINKING symbol.
4262 * configure.in: Add option and checks for dynamic linking.
4263 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
4264 dynl.h: New files for dynamic linking support.
4265 * Makefile.am (libguile_a_SOURCES):
4267 (modinclude_HEADERS): Added "dynl.h".
4268 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
4270 * init.c (scm_boot_guile_1): Call
4271 scm_init_dynamic_linking to initialize dynamic linking support.
4273 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
4275 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
4276 (as we Schemers say). It needs to be global, so that I can tweak
4277 it for the proper operation of unexec.
4278 (scm_boot_guile_1_live): New variable, see above.
4280 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
4282 * guile-snarf.sh: Removed.
4283 * PLUGIN/guile.libs: Added dependency for -lm.
4284 * acinclude.m4: Renamed from aclocal.m4.
4285 * PLUGIN/greet: Removed.
4286 * Makefile.am, aclocal.m4: New files.
4287 * configure.in: Updated for Automake.
4289 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
4291 * eval.c (scm_definedp): Use top_level_lookup_closure_var
4292 and not top_level_lookup_thunk_var.
4294 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
4296 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
4298 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
4300 * eval.c (scm_definedp): Incompatibly changed to be a builtin
4301 Scheme function, instead of syntax. Single argument is now a
4304 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4306 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
4307 scm_ra_divide): Properly terminate statements passed as arguments
4308 to IVDEP macros. (Thanks to Bernard Urban.)
4310 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
4311 with non-constant sizes. (Thanks to Bernard Urban.)
4313 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4315 It's an "eval closure", not an "eval thunk." A thunk is a
4316 function of no arguments.
4317 * root.h (struct scm_root_state): Renamed
4318 top_level_lookup_closure_var from top_level_lookup_thunk_var.
4319 (scm_top_level_lookup_closure_var): Renamed from
4320 scm_top_level_lookup_thunk_var.
4321 * root.c (mark_root): Uses changed.
4322 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
4323 * init.c (scm_start_stack): Uses changed.
4324 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
4325 Change scheme-visible name to *top-level-lookup-closure* from
4326 *top-level-lookup-thunk*.
4328 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
4330 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
4331 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
4333 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
4335 * gc.c (struct scm_heap_seg_data): Doc fixes.
4337 * gc.c (scm_gc_sweep): Empty all segments' freelists before
4338 sweeping. Then, prepend each segment's free cells to its
4339 freelist, rather than wiping out the old value. (Thanks to Marius
4342 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
4343 scm_check_freelist, scm_debug_newcell): New functions and
4344 variables, for debugging freelist problems.
4345 * pairs.h (SCM_NEWCELL): New debugging version added.
4346 * gc.h (scm_debug_newcell): Added extern declaration, used by
4347 debugging version of SCM_NEWCELL.
4349 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4351 On some systems <libc.h> conflicts with <unistd.h>, and should not
4352 be #included at all.
4353 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
4354 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
4355 * configure.in: Call it.
4356 * posix.c, filesys.c: Use its results to decide whether or not to
4358 * configure, scmconfig.h.in: Rebuilt with autoconf and
4361 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4363 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
4364 pointer to the stdio stream before calling scm_setbuf0, so the
4365 latter will be able to retrieve it. I'm surprised this didn't
4366 segfault earlier. (Thanks to Christopher Lee.)
4368 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4370 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
4373 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4375 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
4376 number of stack narrowing specifier pairs. The first specifier in
4377 a pair controls inner border, the second the outer border. A
4378 number means cut that number of frames, a procedure object means
4379 cut until that object is found in operator position in a frame.
4381 * root.c (cwdr): Bugfix.
4383 * read.c: Recording of positions disabled by default.
4385 * procs.c (scm_closure_p): New function.
4387 * posix.c (scm_tmpnam): New function.
4389 * load.c: Added #include "throw.h".
4390 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
4393 * load.c, load.h (scm_read_and_eval_x): New function.
4395 * eval.c: Renamed debug option "deval" to "debug".
4397 (scm_eval_x): `eval!' is no longer accessible from the scheme
4398 level. Motivation: We can't allow operations which introduce
4399 glocs into the scheme level. Guile's type system can't handle
4400 these as data. Use `eval' or `read-and-eval!' as replacement.
4402 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
4403 SCM_CONSP since this is a macro!; Set vframe.prev to
4404 scm_last_debug_frame instead of 0. In this way we can look
4405 "above" the virtual start stack frame if we wish.
4406 (scm_debug_hang): New function: Useful for debugging Guile in
4407 certain tricky situations. Will probably be removed later...
4409 * debug.h: Changed semantics of debug option "backtrace". This
4410 option now only indicates whether we want automatic backtrace at
4413 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4415 * ports.c: #include "filesys.h"
4416 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
4418 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
4419 Motivation: This is system specific code which is related to file
4420 I/O. It also may use select. Added code by Gary Houston to
4421 detect presence of character in stdio buffers.
4423 * libguile.h: #include "libguile/libpath.h"
4425 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
4426 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
4427 SCM_SITE_DIR; Install libpath.h among the other include files.
4429 * load.c, load.h (scm_sys_package_data_dir): New function.
4431 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4433 * stacks.h: Bugfix: Don't use tail-array length field as stack
4434 length field! This screwed GC.
4436 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4438 * _scm.h: Added #ifndef around definition of macros min and max.
4440 * __scm.h: Added hooks for threads to plugin to in ints protection
4441 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
4442 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
4443 the main code in these macros duplicated and spread over multiple
4444 files. Renamed SCM_THREADS_SWITCHING_CODE ->
4445 SCM_THREAD_SWITCHING_CODE.
4447 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
4449 * snarf.h: New file.
4450 * guile-snarf.sh: New file.
4451 * Makefile.in (inner_h_files): Added snarf.h
4452 (ancillary, install, uninstall, distclean): Added actions for
4454 (.c.x): Use guile-snarf.
4455 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
4456 (gen_c_files): Note that these depend on guile-snarf.
4457 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
4458 now in "snarf.h". Added #include "snarf.h" to get them.
4459 * libguile.h: Added #include "snarf.h".
4460 (Patches applied and tweaked by Jim Blandy.)
4462 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4464 * socket.c: Use K&R style declaration for 'close'; the GNU coding
4465 standards suggest against providing prototypes for system
4466 functions. Thanks to Greg Troxel.
4468 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
4470 * strports.c (scm_eval_0str): New function.
4471 #include "read.h", to get prototype for scm_read.
4472 * Makefile.in (strports.o): Update dependencies.
4473 * strports.h: New prototype.
4475 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
4476 scheme name from "int?" to "integer?". It seems to do the job.
4477 * numbers.h: Rename prototype too.
4478 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
4481 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
4482 scm_num_eq_p): Rename these according to R4RS conventions: call
4483 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
4484 to making libguile R4RS compliant without ice-9...
4486 * load.c (scm_sys_search_load_path): Search for files under all
4487 extensions listed in the %load-extensions variable. If FILENAME
4488 is absolute, return it unchanged, without searching the load path.
4489 (scm_loc_load_extensions): New variable, pointing to
4490 %load-extensions' value cell.
4491 (scm_init_load): Initialize it, and the value it points to.
4492 (scm_primitive_load_path): Improve error reporting.
4494 * load.c (scm_loc_load_hook): New variable, pointing to value cell
4495 of new Scheme variable %load-hook.
4496 (scm_primitive_load): Apply %load-hook to filename.
4498 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
4500 * configure.in: add tests for figuring out whether buffered data
4501 is available in a FILE structure, which is needed by char-ready.
4503 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4506 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4507 exceptions using misc_error instead of syserror. It seems a bit
4508 odd to throw an exception if a string can't be found in the
4509 environment, but it's consistent with open-file, stat etc.
4510 (simpos.h): remove sys_ from getenv.
4512 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4513 occurs, throw an error instead of returning errno. Return value
4515 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4517 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4519 * filesys.c (scm_stat2scm): derive file type and permissions from
4520 the stat mode and append them to the returned vector.
4521 There isn't much overhead in doing this and it avoids the need to
4522 work with S_IRUSR et al. in Scheme.
4523 Define symbols scm_sym_regular etc.
4524 (scm_init_filesys): don't intern S_IRUSR etc.
4526 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4527 and s_primitive_load_path.
4529 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4531 * error.h: don't declare error symbols. prototype for scm_misc_error.
4533 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4536 * error.c: use SCM_SYMBOL to set up error keys.
4537 scm_misc_error: new procedure.
4539 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4541 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4542 between `#!' and `!#' is ignored.
4543 (skip_scsh_block_comment): New function.
4545 * feature.c (scm_set_program_arguments): New argument, FIRST.
4546 * feature.h: Update prototype.
4547 * init.c (scm_boot_guile_1): Pass new argument to
4548 scm_set_program_arguments.
4550 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4552 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4553 (scm_boot_guile): Call scm_set_program_arguments here, later than
4554 the old initialization.
4556 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4557 initialization procedure.
4558 - Delete in, out, err arguments; there are other perfectly good
4559 ways to override these when desired.
4560 - Delete result argument; this function shouldn't ever return.
4561 - Rename init_func argument to main_func, for less confusion.
4562 - Delete boot_cmd argument; main_func is more general.
4563 -Add 'closure' argument, to help people pass data to main_func
4564 without resorting to global variables.
4565 - Abort if reentered; don't bother returning an error code.
4566 - Call scm_init_standard_ports to set up the default/current
4567 standard ports; no need to pass them to scm_start_stack.
4568 - Remove code to evaluate the boot_cmd, and start the repl; let
4569 the user do something like that in main_func if they want.
4570 - Remove code to package up a return value; main_func can do any
4572 - Call exit (0), instead of returning.
4573 (scm_start_stack): Don't initialize the I/O ports here; that's
4574 weird. Delete in, out, err arguments. Move guts to
4575 scm_init_standard_ports, scm_stdio_to_port.
4576 (scm_init_standard_ports): New function, to set up current and
4577 default standard ports.
4578 (scm_start_stack, scm_restart_stack): Make these static.
4579 * init.h (scm_boot_guile): Adjust declaration.
4580 (scm_start_stack, scm_restart_stack): Remove externally
4581 visible declarations for these.
4582 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4584 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4585 written out several times in scm_start_stack.
4586 * fports.h: New declaration for the above.
4588 * feature.c (scm_set_program_arguments): New function.
4589 * feature.h: New declaration for the above.
4591 * ports.c: Formatting tweak.
4593 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4595 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4596 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4597 for obtaining the address of a car or cdr field. Motivation:
4598 &SCM_CXR make assumptions about the internal structure of the
4601 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4602 Motivation: see SCM_CXRLOC.
4604 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4605 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4606 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4607 Motivation: Safer use. Some other macros are defined in terms of
4608 these operations. If these are defined using the SCM_SETCXR
4609 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4610 to inefficiency and an <e1> with side-effects could potentially
4611 break. Also, these particular operations are heavily utilized in
4612 the garbage collector. In unoptimized code there will be a
4615 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4616 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4617 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4618 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4619 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4620 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4621 vports.c: Cleaned up use of pairs: Don't make any special
4622 assumptions about the internal structure of selectors and
4623 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4624 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4625 (Among other things, this change makes it easier to build Guile
4626 with certain compilers which have problems with casted lvalues.)
4628 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4630 * stacks.c: Improve selection of relevant stack frames when making
4631 a stack object. Introduce one level of indirection in the stack
4632 object to make it possible to "narrow" to a certain region of the
4633 stack. This facilitates making use of more clever algorithms (not
4634 implemented) for selecting relevant frames and gives a cleaner
4635 design since selection of frames can be done independently of
4636 extraction of frames from the real stack.
4637 (scm_stack_id): Also take #t as argument which means look at
4640 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4641 Turn n_tail into an integer directly representing current number
4642 of frames in stack. Add field tail.
4644 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4646 * debug.c (scm_make_memoized): Made it available at scheme level.
4647 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4648 SCM_NIMP before applying heavier predicates in argument checking.
4649 (scm_local_eval): Also take memoized object as argument.
4651 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4652 aren't created with zero length, but should such a strange
4653 creature suddenly turn up...
4655 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4657 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4658 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4660 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4662 * variable.c (scm_make_variable): Make the name hint optional, as
4664 (anonymous_variable_sym): Renamed from variable_sym. All uses
4667 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4668 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4669 of scm_primitive_load_path was also changed to
4670 "primitive-load-path", from "%try-load-path". Callers changed.
4671 We'd like to respect the convention that a function named
4672 "try-mumble" should behave just like the function called "mumble",
4673 but return #f instead of signalling some error.
4674 * load.h: Rename prototypes.
4676 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4678 * print.c (make_print_state, grow_print_state), print.h: Modified
4679 the print state representation: Don't use a tail array for
4680 recording of circular references. Resizing of the print state
4681 structure invalidates the print state pointer. To avoid passing
4682 around an indirect print state reference to all printing
4683 functions, we instead let the print state reference a resizable
4686 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4688 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4689 Don't crash when passed an improper list terminated by a
4690 non-immediate value.
4692 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4694 Allocate data for structures on an eight-byte boundary, as
4695 required by the tagging system.
4696 * struct.c (alloc_struct): New function.
4697 (scm_make_struct, scm_make_vtable_vtable): Call it.
4698 * struct.h (scm_struct_n_extra_words): Bump to 3.
4699 (scm_struct_i_ptr): New "field".
4700 * gc.c (scm_gc_sweep): When we need to free the data, use the
4701 information stored by alloc_struct to find the beginning of the
4702 block allocated to the structure, so we can free it.
4704 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4706 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4709 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4710 (scm_debug_info): New member: id.
4712 * stacks.c: Stacks are now represented as structs; Stacks have an
4713 id given to them by `start-stack'.
4714 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4716 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4717 Changed stack representation.
4719 * debug.c (scm_procedure_name): Try procedure property `name' for
4720 compiled closures aswell.
4722 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4724 * eval.c: scm_i_name moved to gsubr.c
4725 (scm_m_define): Record names of all kinds of procedure
4726 objects. (Earlier, only closures were recorded.)
4728 * procprop.h: Added declaration of scm_i_name.
4730 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4731 (scm_make_gsubr): Record names of compiled closures.
4733 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4735 * debug.c, debug.h: Removed obsolete code.
4737 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4738 stacks.c: Renamed regs --> scm_contregs.
4740 * print.c (scm_free_print_state): Cleanup print state before
4741 returning it to pool. It is better to do it here than in
4742 scm_prin1 since scm_prin1 is called often.
4744 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4745 s_set_source_property_x): Check that first argument is a pair or a
4748 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4749 scm_i_line, scm_i_column and scm_i_breakpoint global.
4751 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4752 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4755 * debug.h: Added debug object smob declaration and macro
4758 * configure.in: Build with backtrace.o and stacks.o if debug
4761 * Makefile.in: Added entries for new files: backtrace.c,
4762 backtrace.h, stacks.c and stacks.h.
4764 * symbols.c (scm_sym2ovcell): Fixed documentation.
4766 * _scm.h (min, max): Added.
4768 * async.c: Moved `min' macro to _scm.h.
4770 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4771 SCM_BACKTRACE_INDENT.
4773 * eval.c: Added new debug options `maxdepth' and `indent'.
4775 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4777 * print.h: Added selector SCM_PRINT_STATE.
4779 * print.c: New functions: scm_make_print_state,
4780 scm_free_print_state.
4782 * print.h: Added declarations for scm_make_print_state,
4783 scm_free_print_state.
4785 * debug.c (scm_m_start_stack): New acro.
4787 * debug.h: Small cleanup.
4789 * init.c (scm_boot_guile_1): Moved scm_init_debug below
4792 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

4813 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
4814 declare functions with prototypes. (Patch thanks to Marius
4817 More prototype-related changes from Marius Vollmer:
4818 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4819 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4820 * ports.h (ptobfuns): Added prototypes. This means some casting in
4822 * fports.c: Added casts for initializations, since the functions
4823 are defined to take FILE * as their stream argument, not SCM.
4824 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4825 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4826 to `char *str_data' to conform to prototype.
4828 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4830 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4832 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4834 * stime.c, stime.h: use SCM_P method.
4836 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4838 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4839 be given at least two arguments. Insist that lst's last element
4840 be a list, but don't make any requirements of its predecessors.
4842 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4844 * eval.c (scm_nconc2last): Revert last change; there seems to be
4845 other stuff going on here.
4847 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4849 * eval.c (scm_nconc2last): Make sure that each element of lst
4850 (which is a list of argument lists, except for the tail) is a
4851 proper list, i.e., finite and terminated by '().
4853 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4855 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4858 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4859 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4862 * vectors.c (scm_make_vector): Fill vectors with the undefined
4863 value, to help make Guile Scheme code more portable to other
4866 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4867 * symbols.h, tags.h: Doc fixes.
4869 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4871 * async.c (scm_take_signal): Doc fixes.
4873 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4875 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4876 want to subtract it from the modulus; we just want to leave it
4879 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4881 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4884 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4886 * throw.c (scm_catch_apply): Finished implementation of
4889 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4891 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4893 (scm_init_filesys): set "i/o-extensions" feature.
4896 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4898 * Makefile.in (root.o): Correct dependencies.
4900 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4902 * Makefile.in: Added dependency entry for root.o.
4904 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4905 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4907 * init.c (scm_start_stack): Set initial root continuation number
4910 * procs.c: New function: scm_thunk_p.
4912 * procs.h: Added declarations of scm_thunk_p.
4914 * root.c: Renamed `call-with-new-root' -->
4915 `call-with-dynamic-root'.
4916 (cwdr): Removed allocation of new root state. This should be done
4917 separately by use of scm_make_root.
4918 (scm_apply_with_dynamic_root): New function: Does what it
4919 sounds like. Needed when spawning threads.
4921 * root.h: Added member last_debug_frame to root state.
4922 Added #include "libguile/debug.h"
4924 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4925 arguments. The motivation is that code in root.c needs catch
4926 functionality, and we want to avoid code duplication.
4927 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4928 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4929 handlers that run without popping the stack into the dynwind
4932 * throw.h: Added prototypes for scm_catch_apply and
4935 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4937 * root.h (scm_root, scm_set_root): Decouple thread support details
4938 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4939 SCM_SET_THREAD_LOCAL_DATA.
4941 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4942 and tortoise scanning loop.
4944 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4946 * Makefile.in: Rebuild dependencies.
4948 * libguile.h: #include "libguile/print.h" before "smob.h", since
4949 the latter uses the print_state structure.
4951 * throw.c (scm_ithrow): Use the correct variable when checking to
4952 see if a given element of scm_dynwinds is a valid catch.
4954 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4955 structure, abort; don't just silently ignore the garbage.
4957 * _scm.h: #include "print.h" here, since it seems to be used just
4959 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4960 strports.c, unif.h: Don't #include "print.h".
4962 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4964 * feature.h (scm_loc_features): Removed external declaration.
4965 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4967 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4969 * feature.c (scm_init_feature): Added threads feature (needs to be
4970 initialized here, since features doesn't exist when
4971 scm_init_threads is called).
4973 * libguile.h: Added #include "libguile/../threads/threads.h".
4974 (This is a kludge to get thread support working. This should be
4977 * configure.in, acconfig.h: Added flags for thread support.
4979 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4982 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4983 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4986 * _scm.h: Added conditional #include "threads.h"
4988 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4989 SCM_THREADS_SWITCHING_CODE.
4991 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4992 allocate the basic dynamic root object.
4993 (scm_boot_guile): Added call to scm_init_root.
4995 * root.c, root.h: Added root smob.
4996 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4997 functions: Implements dynamic roots mostly according to spec in
4998 SCM manual. Main difference is that the second argument is a
4999 throw handler rather than an error "thunk".
5001 * root.h: Added declaration of scm_init_root.
5003 * root.c: Added #include "genio.h", #include "smob.h", #include
5004 "pairs.h", #include "throw.h", #include "dynwind.h", #include
5006 (scm_init_root): Added #include "root.x".
5008 * throw.c: Added #include "stackchk.h"
5009 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
5010 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
5011 can be used in scm_call_with_new_root; Added reenabling of stack
5012 checking when catching a throw.
5014 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
5016 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
5018 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
5019 element is not found, as per R4RS.
5021 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
5023 * list.c: Doc fixes throughout.
5025 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
5027 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
5028 declare the char * to be const. Avoids a warning in rgx.c.
5030 * ports.h: spelling fix.
5032 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
5035 * load.c (scm_sys_try_load_path): throw an error if file not found
5036 (like it says it in NEWS).
5038 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
5040 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
5041 PROPS slot to '(), not #f; it's an empty alist.
5043 * throw.h, throw.c: Use SCM_P instead of #if hair.
5045 Remove special support for uncaught throws; see throw.c for
5047 * throw.c (uncaught_throw): New function.
5048 (scm_ithrow): Call uncaught_throw if we don't find a throw
5049 target; don't mess with scm_bad_throw_vcell.
5050 (scm_bad_throw_vcell): Variable deleted.
5051 (scm_init_throw): Don't initialize it.
5053 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
5056 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
5058 * numbers.c (scm_istr2int): If the number is short (as most
5059 numbers are), just call scm_small_istr2int to deal with it.
5060 (scm_small_istr2int): New function, created by un-#ifdefing the
5061 non-bignum version of scm_istr2int and renaming it.
5063 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
5065 * load.c (scm_sys_try_load): don't check whether value returned
5066 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
5067 Change the Scheme name from %try-load to primitive-load.
5069 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
5070 Can avoid passing a message, allowing it to be derived in the
5071 error handler (e.g., if we want to throw to the key both from
5074 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
5076 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
5077 references now have a new appearance which is more compact and
5078 also gives a clue about what the target of the reference is.
5079 By setting parameters in the print state, more fancy printing can
5080 be achieved. This is used by the (not yet commited) backtrace
5083 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
5085 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
5088 * print.c: Added #include "struct.h". Removed function
5091 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
5092 scm_iprin1. Removed prototype for scm_prlist.
5094 * arbiters.c (prinarb),
5095 async.c (print_async),
5096 debug.c (prindebugobj, prinmemoized),
5097 eval.c (prinprom, prinmacro),
5098 filesys.c (scm_fd_print, scm_dir_print),
5100 mallocs.c (prinmalloc),
5101 numbers.c, numbers.h (scm_floprint, scm_bigprint),
5102 smob.h (scm_smobfuns),
5103 srcprop.c (prinsrcprops),
5105 unif.c, unif.h (scm_raprin1, rapr1),
5106 variable.c (prin_var): Changed argument `int writing' to
5107 `scm_print_state *pstate'.
5109 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
5110 that it will be called before scm_init_print.
5112 * print.c (scm_prin1): Print states are now allocated when calling
5113 scm_prin1 and then passed around to all printing functions as an
5114 argument. A cache `print_state_pool' enables reuse of print
5116 (scm_make_print_state): New function.
5117 (scm_iprin1): Adaption to print states.
5118 (scm_iprlist): An initial "hare and tortoise" scan brings down
5119 time complexity to O (depth * N). (Better time complexity will be
5120 achieved when the printing code is completely rewritten.)
5122 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
5124 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
5125 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
5126 it gets done whether or not the cache variable has a value.
5128 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5130 Distinguish #f and ().
5131 * __scm.h: #undef SICP.
5132 * pairs.h (SCM_EOL): Delete this definition, equating it with
5134 * tags.h (SCM_EOL): Give it a new definition here; I think I found
5135 the value it used to have. Doc fixes, too.
5137 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
5139 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
5140 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
5141 Lord's implementation of structs, allowing for tail arrays as
5142 described in the manual. Also fixed some bugs. (Both the interface
5143 and the implementation should be improved.)
5145 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
5147 * print.c, print.h: Closures now print like #<procedure foo (x)>.
5148 People who whish to see the source can do `(print-enable 'source)'.
5149 Removed #ifdef DEBUG_EXTENSIONS.
5151 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5153 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
5154 integer (assuming for now accepting an integer is a good thing).
5156 * error.c, fports.c: replace use of %S in lgh_error args with %s.
5157 %S will be used instead for write'ing arguments.
5159 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
5160 asserts. fix a few other asserts.
5161 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
5162 scm_uniform_vector_ref, scm_array_set_x,
5163 scm_dimensions_to_unform_array): change args in
5164 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
5165 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
5166 scm_substring_fill_x): likewise.
5167 gsubr.c (scm_gsubr_apply): likewise.
5168 eval.c (SCM_APPLY): likewise.
5170 * eval.c (4 places): replace scm_everr with lgh_error or
5173 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
5174 scm_memory_error): new procedures.
5175 scm_everr: deleted. can use scm_wta, dropping first two args.
5176 scm_error: convert NULL subr to SCM_BOOL_F.
5178 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
5181 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
5184 * error.c, error.h: new error keys: scm_arg_type_key,
5185 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
5187 scm_wta: reimplement using lgh_error instead of scm_everr.
5189 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
5191 * gdbint.c: scm_lread now has one more argument.
5193 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
5194 scm_port_\1; Added mutator scm_set_port_filename_x (used when
5195 loading source from non-file ports, which, e. g., happens when
5196 using the Emacs interface).
5198 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
5201 * read.c: Added code for recording of positions of source code
5202 expressions; New functions: recsexpr, scm_lreadrecparen;
5203 _scm_make_srcprops --> scm_make_srcprops
5204 (scm_flush_ws): Removed updating of positions counters. This work
5205 is already done by scm_gen_getc
5207 * read.h: Added prototype for scm_lreadrecparen
5209 * print.c: Added #include "alist.h"
5211 * eval.c: Added #include "hash.h"
5213 * eq.c: Added #include "ramap.h"
5215 * options.c: Documentation fixes.
5217 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
5218 (scm_init_srcprop): Adjusted size of initial source-whash. Name
5219 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
5220 --> scm_make_srcprops
5222 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
5223 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
5224 function calls in the definition of the whash access macros.
5226 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
5228 * init.c (scm_boot_guile): Add level of indirection to
5229 scm_boot_guile_1() to ensure that stack base pointer is properly
5230 initialized. There was no guarantee that variable i was the
5231 highest/lowest variable on stack (i.e. the call frame of
5232 scm_boot_guile was not completely protected from gc).
5234 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
5236 * ports.h (scm_port_table): put back file_name, it will be used to
5237 support debugging. Undo related changes in fports.c, ioext.c,
5240 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
5242 * ports.h (scm_port_table): remove file_name member for now, it seems
5244 * fports.c (scm_open_file): don't set file_name in PTAB.
5245 (prinfport): don't use file_name in PTAB.
5246 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
5247 * ports.c (scm_add_to_port_table): don't intialize file_name.
5248 (scm_port_file_name): remove for now.
5249 * gc.c (scm_gc_mark): don't mark PTAB file_name.
5251 * fports.h (scm_mkfile): prototype deleted.
5252 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
5254 * debug.c, unif.c: use scm_out_of_range instead of
5255 wta for range errors (ASSERT still needs work).
5257 * error.c, error.h (scm_out_of_range): new procedure.
5259 * error.c, error.h (scm_out_of_range_key): new key.
5261 * posix.c (scm_sync): #else was missing.
5263 * error.c, error.h: append _key to names scm_num_overflow and
5266 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
5267 of consing an empty list.
5268 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
5269 of macros, saves code and string space.
5270 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
5271 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
5272 lower case. Rename scm_syserror_m to scm_syserror_msg.
5273 error.h: prototypes for new procedures.
5275 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
5277 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
5279 * error.c, error.h: setup scm_num_overflow key.
5281 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
5282 Remove definition of SCM_OVSCM_FLOW.
5284 * fports.c (scm_open_file): use SCM_SYSERROR_M.
5286 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
5287 explicit message and args.
5289 * error.c, error.h, __scm.h: change system_error_sym to
5292 * error.c (system_error_sym): remove leading %% from the Scheme name
5295 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
5297 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5299 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
5300 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
5301 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
5302 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
5303 renamed. (These were introduced by unsupervised name
5306 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5308 * print.c: Added code for detection of circular references during
5309 printing. (init_ref_stack, grow_ref_stack): New functions. Added
5310 a hook for printing of closures (accessible via print options).
5311 This leads to a split of calls to scm_iprin1 into two classes:
5312 elementary print operations (e. g. the code which prints a smob)
5313 still use scm_iprin1 while top level calls (like scm_display) use
5314 scm_prin1. scm_prin1 begins by clearing the data structure used
5315 to record reference information.
5317 * print.h: Added declarations of scm_prin1 and scm_prlist.
5319 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
5321 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
5323 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
5325 * error.c (err_head): scm_iprin1 --> scm_prin1
5327 * debug.c: Adjusted header comment.
5331 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
5333 * strerror.c: Doc fix.
5335 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5337 * gdbint.c (gdb_read): Now possible to run during GC.
5338 (unmark_port, remark_port): New functions.
5340 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
5342 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
5343 of allocating a new string object. Also, increase size by
5344 the factor 2 instead of 1.5.
5346 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
5348 * __scm.h (SCM_P): Corrected to run under traditional C.
5350 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
5353 * async.c: Calls to scm_sysintern corrected.
5355 * async.h (scm_async_clock): Redundant declaration removed.
5357 * continuations.c (scm_dynthrow): Redundant declaration removed.
5359 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
5360 Definition typos corrected.
5362 * debug.h: Missing declarations of functions in debug.c added
5365 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
5366 Missing declarations to functions in eval.c added.
5368 * filesys.c: Possibly uninitialized variable rv.
5370 * gc.h (scm_object_addr, scm_unhash_name): Missing
5371 declarations of functions defined in gc.c added.
5373 * genio.c: Possible typos str_data -> wstr_data. ???
5375 * genio.c: Possibly unintended shadowing of local variable
5376 `int c' (gotos out of scope of inner `c'). ???
5378 * init.c: Uninitialized `SCM last' may be used.
5380 * ioext.h: (scm_sys_isatty_p): Typo.
5382 * list.h (scm_list_head): Missing prototype for function in
5385 * numbers.c (scm_two_doubles): Changed from extern to static
5386 (is used only within numbers.c).
5388 * numbers.h: Repeated declarations removed.
5390 * ports.h (scm_close_all_ports_except): Declaration for the
5391 function defined in ports.c added.
5393 * posix.h: Missing declarations added.
5395 * procs.h (scm_make_subr_opt): Missing declaration added.
5397 * socket.h (scm_sys_gethost): Missing declaration added.
5399 * socket.h: Redundant declarations removed (they are in fdsocket.h).
5401 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
5402 Missing declarations added.
5404 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
5406 * struct.c: Uninitialized variable `SCM answer' may be used.
5408 * unif.c (l2ra): Declaration prototype.
5410 * unif.c (scm_array_equal_p): Dummy definition removed (it is
5411 defined in ramap.c).
5413 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
5414 Redundant declarations removed (they are in ramap.h).
5416 * variable.h (scm_make_udvariable,
5417 scm_make_undefined_variable): Declaration corrected to
5418 correspond variable.c.
5420 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
5421 Missing declarations added.
5423 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
5425 * Makefile.in (distclean): Don't forget to delete fd.h.
5427 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
5429 * fd.h.in, tags.h: Trivial cleanups.
5431 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
5432 marksweep.h just declared functions from gc.c.
5433 * gc.h, libguile.h: Don't #include "marksweep.h".
5434 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5435 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
5436 dependencies updated.
5438 * libguile.h: Don't #include "files.h"; it's been deleted.
5440 * files.c (scm_sys_delete_file): Moved to filesys.c.
5441 File is now empty; deleted.
5443 * filesys.c: scm_sys_delete_file is now here. Remove
5444 #if's; they seem to rely on remnants of an old portability
5445 regimen. If the problems come up again, solve them properly,
5446 using autoconf. Specifically: Don't test M_SYSV, and #define
5447 remove to be unlink if it's #defined; don't use remove just
5448 because HAVE_STDC_HEADERS is #defined.
5449 * filesys.h: Add declarations for scm_sys_delete_file.
5450 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
5451 files.o, files.h, files.c, and files.x.
5452 * init.c: Don't #include "files.h", and don't call scm_init_files.
5454 Use SCM_P instead of PROTO; the latter intrudes on the user's
5456 * params.h: Deleted; definition of SCM_P moved to...
5457 * __scm.h: ... here, where it replaces PROTO macro.
5458 * libguile.h, smob.h: Don't #include "params.h".
5459 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
5460 smob.h: Fix prototypes accordingly.
5461 * Makefile.in: Update dependencies.
5462 (inner_h_files): Remove params.h.
5464 * gc.c: #include "gc.h"; every module should include its header,
5465 to let the compiler cross-check the declarations against the
5468 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
5469 simpos.h: #include "libguile/__scm.h".
5471 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
5473 * init.c: Don't forget to #include smob.h and init.h.
5474 * Makefile.in: Dependencies updated.
5476 * smob.h: Use PROTO instead of #if __STDC__.
5478 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
5480 * __scm.h: Doc fixes.
5482 * __scm.h, libguile.h: Use "quotes" in the #includes, not
5483 <angles>; this allows `make depends' to work properly.
5485 * libguile.h: #include smob.h and pairs.h before the others; they
5486 define typedefs used by other headers.
5488 C files should #include only the header files they need, not
5489 libguile.h (which #includes all the header files); the pointless
5490 recompilation was wasting my time.
5491 * Makefile.in (all .o dependency lists): Regenerated.
5492 * libguile.h: Don't try to get a definition for size_t here...
5493 * __scm.h: Do it here.
5494 * _scm.h: Since this is the internal libguile header, put things
5495 here that all (or a majority) of the libguile files will want.
5496 Don't #include <libguile.h> here; that generates dependencies on
5497 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
5498 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
5499 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5596 * weaks.c: Get "weaks.h".
5598 * stackchk.h: #include "libguile/debug.h",
5600 * print.h, read.h: #include "options.h", since everyone who uses
5601 either of these files will need that.
5603 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5604 anyone who uses this file will need them to define the smob
5605 printing functions. Also, get markers.h, since people will need
5606 to #define the mark functions.
5608 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5609 * ports.h: ... to here.
5611 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5612 don't rely on archaic C default type rules.
5614 * fports.h: #include "libguile/ports.h", since you need that in
5615 order to parse this.
5617 * genio.h: #include "libguile/print.h", because you need that to
5618 parse this; don't bother #including "ports.h", since print.h gets
5621 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5623 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5624 this; it's now a reference to an element of *scm_root.
5626 * debug.h: Don't #include "options.h"; the compiler won't be able
5627 to find that once the headers are installed; instead, #include
5628 "libguile/options.h".
5629 * gc.h: Same, with marksweep.h.
5630 * mbstrings.h: Same, with symbols.h.
5631 * scmhob.h: Same, with _scm.h.
5632 * smob.h: Same, with params.h.
5634 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5635 C files; there's no need for this, and it forces recompilations
5638 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5640 * error.c (scm_error): declare scm_error_callback.
5642 * error.h: prototype for scm_error_callback.
5644 * __scm.h: define lgh_error.
5645 (SCM_SYSERROR): redefine using lgh_error.
5647 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5649 * error.c (scm_error): new procedure.
5651 * error.h: prototype for scm_error.
5653 * Makefile.in (install): install scmconfig.h from the current
5654 directory, not $(srcdir).
5656 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5658 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5659 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5660 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
5661 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,

5665 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5666 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5667 vports.h, weaks.h: #include "libguile/__scm.h", not
5668 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5669 dependencies are within libguile properly.
5671 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5673 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5674 when scmconfig.h doesn't exist.
5676 * load.c (scm_sys_try_load): Correct spelling.
5678 * feature.c (scm_loc_features): Make this static.
5680 * Makefile.in (libpath.h): Omit trailing slash from path. We
5681 shouldn't require it of users, so why put it here?
5683 Move code to initialize and search %load-path from ice-9 to C
5684 code, so we can use the load-path to find the ice-9 boot code;
5685 this makes it easier to run Guile without installing it. See
5686 corresponding changes in guile/Makefile.in.
5687 * feature.c: Move stuff concerned with the load path to load.c.
5688 (scm_compiled_library_path): Deleted.
5689 Don't #include libpath.h here.
5690 * feature.h: Don't mention scm_compiled_library_path.
5691 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5692 <sys/stat.h>, and <unistd.h> (if present).
5693 (R_OK): #define if the system hasn't deigned to.
5694 (scm_loc_load_path): New variable.
5695 (scm_init_load_path, scm_sys_search_load_path,
5696 scm_sys_try_load_path): New functions.
5697 (scm_init_load): Initialize scm_loc_load_path to point to the
5698 value cell of the Scheme %load-path variable.
5699 * load.h: Add declarations for scm_sys_search_load_path,
5700 scm_sys_try_load_path.
5701 * init.c: Call scm_init_load_path.
5702 * Makefile.in (feature.o, load.o): Dependencies updated.
5704 * load.c, load.h: Rewrite using PROTO macro.
5706 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5708 * gc.c (scm_cellp): New function: C predicate to determine if an
5709 SCM value can be regarded as a pointer to a cell on the heap.
5711 * gc.h: Added declaration of scm_cellp.
5713 * gdb_interface.h: New file: The GDB interface header from the GDB
5716 * gdbint.c: New file: GDB interface.
5718 * gdbint.h: New file: GDB interface.
5720 * libguile.h: Added #include <libguile/gdbint.h>.
5722 * init.c (scm_boot_guile): Added scm_init_gdbint.
5724 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5725 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5726 found if object files and source are kept separate).
5728 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5730 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5732 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5734 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5735 TK_SRC_DIR; they're not relevant any more.
5737 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5738 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5740 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5742 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5743 search path, so we can find the <libguile/MUMBLE.h> headers.
5745 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5747 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5748 implicit in the .c.o rule.
5749 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5752 Put the library path in a header file, instead of passing it on
5753 the command line in every compilation.
5754 * Makefile.in (libpath.h): New target.
5755 (feature.o): Depend on libpath.h.
5756 (clean): Delete libpath.h.
5757 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5758 * feature.c: ... #include "libpath.h" here.
5759 * .cvsignore: Ignore libpath.h.
5761 Don't install the unwashed masses of Guile header files in the
5762 main #include path; put most of them in a subdirectory called
5763 'libguile'. This avoids naming conflicts between Guile header
5764 files and system header files (of which there were a few).
5765 * Makefile.in (pkgincludedir): Deleted.
5766 (innerincludedir): New variable; this and $(includedir) are enough.
5767 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5768 (installed_h_files): Divide this up. Now this variable lists
5769 those header files which should go into $(includedir) (i.e. appear
5770 directly in the #include path), and ...
5771 (inner_h_files): ... this new variable says which files appear in
5772 a subdirectory, and are referred to as <libguile/mumble.h>.
5773 (h_files): List them both.
5774 (install): Create innerincludedir, not pkgincludedir. Put
5775 the installed_h_files and inner_h_files in their proper places.
5776 (uninstall): Corresponding changes.
5777 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5778 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5779 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5780 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5781 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5782 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5783 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5784 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5785 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5786 vports.h, weaks.h: Find __scm.h in its new location.
5787 * __scm.h: Find scmconfig.h and tags.h in their new locations
5788 (they're both "inner" files).
5790 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5792 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5794 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5796 * posix.c: Doc fixes.
5798 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5800 * socket.c: Don't include a prototype for inet_aton; just use a
5801 K&R style declaration, to avoid warnings but minimize the chance
5802 of conflicts with the system.
5804 On NextStep, <utime.h> doesn't define struct utime, unless we
5805 #define _POSIX_SOURCE before #including it.
5806 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5807 * acconfig.h: New comment text for above CPP symbol.
5808 * configure.in: Call it.
5809 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5811 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5813 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5814 testing for __EMX__.
5816 * posix.c: #include <libc.h>, if it exists.
5818 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5819 don't even know if the latter exists.
5821 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5822 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5823 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5825 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5827 (scm_init_posix): Use them when initializing the Scheme constants
5830 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5832 * Makefile.in (libdir, includedir, bindir): Use the
5833 autoconf-supplied values, instead of deriving them ourselves.
5834 (pkgincludedir, datadir, pkgdatadir): New variables.
5835 (install, uninstall): Put the header files in a special
5836 subdirectory, not in the main search path.
5838 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5839 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5841 * Makefile.in (IMPLPATH): Deleted; never used.
5843 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5844 on the Tcl/Tk source any more.
5845 (INCLUDE_CFLAGS): Remove references to the above.
5847 * Makefile.in (version.o): Corrected dependencies.
5849 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5851 * libguile.h: #include "version.h"
5853 * init.c (scm_boot_guile): Call scm_init_version.
5854 * gscm.c (gscm_run_scm): Call scm_init_version.
5856 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5857 GUILE_VERSION): AC_DEFINE these.
5858 (acconfig.h): #undef the above symbols.
5860 * Makefile.in (libobjs): Add version.o.
5861 (installed_h_files): Add version.h.
5862 (c_files): Add version.c.
5863 (gen_c_files): Add version.x.
5864 (version.o): New rule.
5865 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5866 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
5867 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
5868 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
5869 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
5870 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
5871 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
5872 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
5873 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
5874 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5875 weaks.o): Add version.h to dependency lists.
5876 (markers.o): Remove duplicate rule.
5878 * version.h: New file.
5880 * version.c: New file.
5882 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5884 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5885 array; use it appropriately. Since GCC is quite happy to
5886 subscript functions, it never warned us about this; we should use
5887 -Wpointer-arith in the future. I guess we never tested
5890 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5892 * socket.c: Doc and copyright fixes.
5894 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5896 * debug.c: Fixed and improved gdb support.
5898 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5900 * socket.c: Added declaration of inet_aton to avoid compiler
5901 warning. (Hope this solution is correct.)
5903 * stime.c: Added declaration of ftime. (This is missing in
5906 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5908 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5910 * Makefile.in (c_files): add strerror.c.
5912 * strerror.c: new file from Emacs' sysdep.c.
5913 maybe configure should also check for sys_errlist.
5915 * configure.in (AC_REPLACE_FUNCS): add strerror.
5917 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5919 * debug.c (scm_init_debug): Added initialization for
5920 scm_evaluator_traps.
5922 * debug.h, debug.c: Various name changes.
5923 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5924 "debug-options-interface". See commentary in options.c.
5926 * options.h, options.c: Options now have documentation strings.
5927 Also added a long explanatory commentary.
5929 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5932 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5933 last_debug_info_frame is now updated in all cases.
5935 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5938 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5940 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5941 Added option STACK_CHECKING.
5943 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5945 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5947 * __scm.h: Removed symbols for debugging support.
5949 * acconfig.h: Added symbols for debugging support.
5951 * configure.in: Added user option for debugging support.
5952 --enable-debug will include the debugging code into libguile.a.
5954 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5955 scm_relocate_chunk_to_heap.
5957 * debug.c: New file: low-level debugging support. It also
5958 includes support for debugging with gdb. (The extensions to gdb
5959 are written by Per Bothner at Cygnus.)
5961 * debug.h: New file: low-level debugging support.
5963 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5964 argument pairs. Extensive modifications to the debugging
5965 evaluator. Added "SECTION:" commentaries to clarify what happens
5966 when, during double compilation. Renamed EVALIMP --> EVALIM.
5967 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5968 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5969 the beginning of the file. New procedure: scm_unmemocopy.
5970 Added some global state variables needed by the debugging
5971 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5972 check_entry, check_apply, check_exit, debug_options and
5973 evaluator_traps. New acro: undefine.
5975 * eval.h: Renamed EVAL --> XEVAL.
5977 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5978 --> scm_make_weak_key_hash_table.
5980 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5981 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5983 * libguile.h: Conditionally include debug.h
5985 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5986 scm_object_properties shouldn't return handle. `handle' now gets
5987 initialized in scm_set_object_properties_x. scm_object_properties
5988 doesn't any longer create an entry in scm_object_whash.
5990 * options.c: New file: handling of run time options.
5992 * options.h: New file: handling of run time options.
5994 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5996 * print.c: New procedure: scm_print_options
5998 * print.h: Defines for print options.
6000 * read.c: New procedure: scm_read_options
6002 * read.h: Defines for reader options.
6004 * root.h: Added scm_source_whash among scm_sys_protects.
6006 * srcprop.c: New file: source properties.
6008 * srcprop.h: New file: source properties.
6010 * throw.c (jbsmob): Jump buffers are now correctly allocated.
6011 (Bug found by A. Green.)
6013 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
6015 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
6017 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
6019 * libguile.h: #include "objprop.h"; I guess this was forgotten.
6021 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
6022 and should be called by the final client.
6024 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
6026 * gc.h: Use the PROTO macro when declaring functions.
6027 * gc.c: Use the PROTO macro when declaring static functions.
6028 Remove the CPP hair around function definitions.
6030 * gc.c (scm_init_storage): Initialize scm_asyncs.
6032 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
6033 preprocessor symbol; "__scm.h" is where it might get #defined.
6034 * __scm.h: Similar: #include <scmconfig.h> before testing
6037 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
6039 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
6041 * init.c (scm_boot_guile): Add init_func argument; call
6042 (*init_func) instead of calling scm_appinit; it's ucky to
6043 hard-code names for the user's procedures.
6044 * init.h (scm_boot_guile): Adjust declaration.
6046 * __scm.h (PROTO): New macro, for declaring functions with
6049 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
6050 eliminate all the __STDC__ conditionals.
6051 (scm_boot_guile): Add declaration.
6052 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
6053 Remove __STDC__ conditionals around function definitions; the
6054 declarations in init.h will provide the same information, more
6057 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
6058 complain about it in the error message; the error message is
6059 adequate without that note, and there's nothing the user can do
6062 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
6064 * Makefile.in (ancillary): Drop def.sed.
6066 * posix.c (scm_init_posix): Use numeric values, rather than
6067 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
6068 F_OK. The symbols aren't available on some systems, and I'm
6069 pretty sure their values are fixed by common widespread practice.
6070 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
6072 More functions unavailable on some systems.
6073 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
6074 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
6076 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
6077 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
6078 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
6079 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
6080 stub that signals an error as the #else.
6082 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
6084 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
6086 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
6088 * unif.c: include ramap.h.
6090 * read.c (endif): case_insensative_p renamed case_insensitive_p.
6092 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
6094 * ports.c: include sys/ioctl.h.
6096 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
6098 * configure.in: check for sys/ioctl.h.
6100 * ports.c: include <malloc.h> not "malloc.h".
6102 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6104 * fports.c: remove ttyname and tmpnam declarations.
6106 * posix.c: fewer ttyname declarations.
6108 * fports.c: include <string.h> not "string.h".
6110 * init.c, ioext.c: include string.h and unistd.h.
6112 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
6114 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
6115 genio.c, simpos.c, vports.c: include string.h.
6117 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
6119 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
6121 (scm_addr_buffer_size): change type from scm_sizet to int.
6122 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
6123 from scm_sizet to int.
6125 * error.c: include unistd.h.
6127 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
6130 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
6132 * __scm.hd, def.sed: deleted.
6134 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
6136 Changes for NeXT, suggested by Robert Brown.
6137 * configure.in: Call AC_TYPE_MODE_T.
6138 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
6139 NeXT. Put header file list in alphabetical order.
6140 * configure, scmconfig.h.in: Regenerated.
6141 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
6143 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
6146 * acconfig.h: New file, providing documentation for the CPP
6147 symbols defined in configure.in
6148 * acconfig-1.5.h: Removed; superceded by the above.
6150 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
6152 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
6154 * fports.c (scm_open_file): don't return #f, throw error.
6156 * ioext.c (fileno): renamed from %fileno.
6157 (soft-fileno): deleted.
6159 * ports.c (scm_port_revealed): don't need to check for -1 from
6161 (scm_set_port_revealed_x): return unspecified, not #f.
6163 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
6165 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
6167 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
6169 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
6171 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
6173 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
6174 This is necessary on Ultrix, and doesn't hurt portability.
6176 * Makefile.in (dist-dir): New target, implementing a new dist system.
6177 (installed_h_files): Put in alphabetical order.
6178 Remove duplicate entries for markers.h and unif.h.
6179 (c_files): Remove duplicate entries for markers.c.
6180 (ancillary): Renamed from anillery; all uses changed. Remove
6181 PLUGIN; it's a directory, and needs special treatment in dist-dir.
6182 Remove all the ../doc/* files; doc/Makefile.in handles that.
6184 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
6186 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
6187 every if must have an else, or else the whole command has a
6188 non-zero exit code whenever the if's condition is false.
6190 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
6192 * posix.c: include string.h.
6194 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
6196 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
6199 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
6200 Remove leading % from scheme names.
6201 Do not return error values, call SCM_SYSERROR or similar.
6203 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
6205 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
6207 * struct.c (scm_init_struct): new file.
6209 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
6211 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
6212 (scm_list_head): added list-head for rapidly chopping argument
6213 lists off of longer lists (and similar).
6215 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
6217 * objprop.c (scm_object_property): assq the cdr of the whash
6218 handle for obj, not the handle itself.
6220 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
6222 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
6223 weak hash tables last of all marking to avoid an obscure gc bug.
6224 WARNING: circular lists stored in a weak hash table will hose us.
6226 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
6228 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
6229 new functions similar to scm_substring_move_left_x and
6230 scm_substring_move_right_x.
6232 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
6234 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
6237 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
6239 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
6241 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
6243 * strports.c (scm_strprint_obj): convenience function. C for
6244 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
6246 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
6247 removed to a separate library
6249 * init.c (scm_boot_guile): copied from guile-tcl.c.
6250 Initialization specific to tcl interpreters removed.
6252 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
6254 * ports.c (scm_ports_prehistory): size malloced here doesn't
6255 matter so long as it is non-0 (got rid of "* 4").
6257 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
6259 * gscm.h: gscm_mkarray eliminated (presumably was not being used

6264 * mallocs.[ch]: back again (for rx at least).
6266 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
6268 * ports.c: removed functions relating to the mapping between ports
6269 and descriptors. (That stuff is unix-specific and should be collected

6277 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
6278 handled correctly (SCM_FREEP was applied to them) -- test for
6279 NIMP. Keys in weak hash tables were spuriously (though harmlessly)

6324 (possibly triggering gc) before setting the tag of the corresponding
6327 * pairs.c (scm_delq_x): never throw an error.
6329 * vectors.c (scm_make_vector): made the default vector fill argument

6334 * ports.c (scm_add_to_port_table): Added fields
6335 to port table entries: file_name, line_num, col.

6447 initialization to fix a race condition.
6449 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

6473 set the multi_byte flag correctly in symbols. This is wrong.
6474 intern_obbary_soft and msymbolize should take an extra parameter.
6475 Also, weird multibyte symbols don't print correctly.
6476 The weird symbol syntax is also a bit bogus (emacs doesn't quite
